Definitions
- the present invention relates to mats, desirably disposable non-slip mats such as disposable toilet or potty training mats that have a removable portion and a holding mechanism configured to increase the resistance of the article to movement.
- Protective toilet or potty mats are often useful in situations where a person, particularly a child, is being toilet trained, or in a circumstance where maintaining a sanitary environment is of particular importance, such as in a hospital or in an elder care environment. It is generally desirable in such situations to protect the area surrounding the toilet or potty chair from bodily exudates, such as urine, which may be present. As such, a mat that isolates the immediate area around the toilet or potty chair is desired. Moreover, in a situation where such an article is used in connection with a child being trained, it is desired that such an article encourages and reinforces toilet and potty use.
- mats or pads have not always been fully responsive to the desire to create a positive and supportive training environment. That is, existing mats or pads may not remind a child as to where they may suitably orient themselves with respect to the potty or toilet. In addition, existing options may not provide a positive or even fun environment in which to train.
- the present invention concerns a disposable mat defining a longitudinal direction, a lateral direction and at least one edge.
- the disposable mat includes a first face, a second face opposite the first face, and at least one line of weakness.
- the at least one line of weakness is configured to allow the separation of a removable portion from the disposable mat.
- the mat also includes a holding mechanism configured to increase the resistance of the mat to movement when the first face of the mat is placed upon a planar surface.
- the present invention concerns a disposable mat defining a longitudinal direction, a lateral direction, a pair of side edges that are parallel to the longitudinal direction and a pair of end edges that are parallel to the lateral direction.
- the disposable mat includes an operatively liquid impermeable first face, an absorbent second face opposite said first face, and at least one line of weakness.
- the at least one line of weakness is configured to allow the removal of a portion of the disposable mat.
- the mat also includes a holding mechanism that is configured to increase the resistance of the mat to movement when the first face of the mat is placed upon a planar surface, and a pair of first reference marks located on the second face.

- the potty location mark 58 may be a silhouette of a potty chair, or may be a potty chair shaped flower, baseball, sun, or other suitable object. It should be noted that the potty location mark 58 may be located within the removable portion 36 , intersect the at least one line of weakness 29 , or may otherwise be located within the perimeter 40 of the mat 20 .
- the potty mat 20 may include a pair of first reference marks 50 located between a pair of opposing lines of weakness, 30 and 31 , as representatively illustrated in FIG. 8 .
- the user or caregiver may select whether the potty mat 20 should be configured to be used while standing and toileting or sitting while toileting. Accordingly, such an embodiment would allow the selection of a gender specific orientation with only a single pair of reference marks 50 .
- the user or caregiver may use the first line of weakness 30 to separate the removable portion 36 that the first reference marks 50 are pointing at.
- the first reference marks 50 would indicate where the feet of the user should be placed when standing while toileting.
- the user or caregiver may use the second line of weakness 31 to separate the removable portion 36 that the first reference marks 50 are pointing away from. In such an arrangement, the first reference marks 50 would indicate where the feet of the user should be placed when sitting while toileting.
- the mat 20 may also include a pair of second reference marks 52 on the second face 22 . Similar to the first reference marks 50 , the second reference marks 52 may also be configured to indicate where the feet of the user should be placed when the user is toileting. However, the second reference marks 52 may be used to indicate where the feet of the user should be placed when using the toilet or the potty chair differently than when the user is using the potty chair according to the first reference marks 50 . That is, the first reference marks 50 may be provided to indicate where the feet of the user should be placed when using the toilet or potty chair while standing. Accordingly, in such an arrangement, the second reference marks 52 may be provided to indicate where the feet of the user should be placed when using the toilet or potty chair while sitting.
- the first and second reference marks 50 and 52 may both be associated with the same line of weakness 30 or potty location mark 58 .
- the first and second reference marks 50 and 52 may be associated with different lines of weakness 30 or potty location marks 58 or combinations thereof.
- the pair of first reference marks 50 may be associated with a first line of weakness 30 and indicate one orientation for a user's feet (in this instance standing), while the pair of second reference marks 52 may be associated with a second line of weakness 31 and indicate a different orientation for a user's feet (in this instance sitting).
- a potty mat 20 including both first and second reference marks 50 and 52 may optionally have gender specific configurations.
- first and second reference marks 50 and 52 may each be located on the removable portions 36 that are provided by the first and second lines of weakness 30 and 31 .
- the user or the caregiver may optionally configure the mat 20 for use while sitting or while standing by removing the desired removable portion 36 , and consequently, the reference marks 50 or 52 that may no longer be required is also removed.
- the removable portion 36 may be separated from the mat 20 at the first line of weakness 30 .
- the second reference marks 52 are also removed.
- the removable portion 36 may be separated from the mat 20 at the second line of weakness 31 .
- the first reference marks 50 are also removed.
- the above mat 20 configuration may be helpful in a situation where the toileting process is desired to be as simple as possible, such as when toilet training small children.
- the individual objects that make up the pair of reference marks 50 or 52 may each be located a substantially equal distance from the at least one line of weakness 29 or the potty location mark 58 . Therefore, if a pair of reference marks 50 or 52 is provided by a pair of feet, each foot may be located a substantially equal distance from the at least one line of weakness or the potty location mark 58 . As used herein in connection with the reference marks 50 and 52 , a “substantially equal distance” means the distances are within 5 cm of each other.
- the other foot should be between 5 cm and 15 cm away so the pair of reference marks 50 or 52 is located a substantially equal distance from the at least one line of weakness 29 or the potty location mark 58 .
- the pair of first reference marks 50 each may be located a first substantially equal distance from the at least one line of weakness 29 or the potty location mark 58 .
- the distance between the at least one line of weakness 29 or the potty location mark 58 and the pair of first reference marks 50 may be a first substantially equal distance 84 of between 5 cm and 22 cm.
- the distance between the at least one line of weakness 29 or the potty location mark 58 and the pair of second reference marks 52 may be a second substantially equal distance 86 of between 12 cm and 30 cm. This distance may be measured by measuring the shortest linear distance between the reference marks and the line of weakness or potty location mark, as shown in FIGS. 3, 4 and 5 .
- the reference marks 50 and 52 of the present invention may be depicted by graphics located on the second surface 24 of the mat 20 .
- the graphics may be any suitable figure, object or symbol.
- the nature of the graphic should be such that the user associates the graphic with where they should stand.
- the graphic can be a pair of foot prints, animal paws or hooves, or the soles of shoes or boots or other footware, and the like or combinations thereof.
- the graphics for a pair of reference marks 50 or 52 may be two different objects.
- the graphics for a pair of reference marks 50 or 52 may be substantially similar (i.e. a left and right foot or a left and right shoe), or identical. As representatively illustrated in FIGS.
- the mat includes a pair of first reference marks 50 provided by a set of first graphics 54 .
- the set of first graphics 54 are a pair of feet or other foot ware, thus making the set of first graphics 54 providing the first reference marks 50 substantially similar.
- the mat includes a pair of second reference marks 52 provided by a set of second graphics 56 .
- the set of second graphics 56 are a pair of feet, thus making the second graphics providing the second reference marks 52 substantially similar.
- the set of first graphics and set of second graphics 54 and 56 for the first and second reference marks 50 and 52 may be substantially similar (i.e. a pair of left and right feet or shoes, but they may be pointing in different directions) or identical.
- the set of first graphics and set of second graphics 54 and 56 for the first and second reference marks 50 and 52 may be different to further distinguish them from each other.
- the first and second graphics 54 and 56 may be different in order to make the first and second graphics 54 and 56 gender specific. Such an arrangement may be particularly useful to assist with toilet training children.
- the reference mark 50 or 52 that indicates where the user should place their feet when standing may be provided by graphics 54 or 56 that are generally of interest to young boys.
- the reference mark 50 or 52 that indicates where the user should place their feet when sitting may be provided by graphics 54 or 56 that are generally of interest to young girls. This arrangement may be used regardless of whether the first and second reference marks 50 and 52 are associated with the same line of weakness 30 or potty location mark 58 or not.
- the mat 20 may also include at least one decorative graphic 60 located on the second face 24 of the mat 20 .
- the decorative graphics 60 may be any suitable figure, object, or symbol.
- the decorative graphics include planets, rockets, and other objects directed to “space.”
- the decorative graphics 60 include fish, boats, and other nautical objects.
- the decorative graphics 60 may be related or unrelated. In particular aspects, and as described above, the decorative graphics 60 may collectively have a unifying decorative graphic theme (i.e. “space” and “nautical”).
- the themes may enhance the aesthetic qualities of the mat, including largely ornamental graphics, or if using the mat 20 in connection with toilet training a child, the graphics can be attractive to a child, gender specific, or relate to a character or story popular with children.
- the graphics 60 in one area of the mat 20 may be of one theme, while the graphics 60 in another area of the mat 20 may be of a different theme.
- the graphics 60 on one portion of the mat 20 are directed to a nature theme while the graphics 60 on another portion of the mat 20 are directed to a sporting theme.
- This arrangement may be useful where there is a first and second line of weakness 30 and 31 or a line of weakness 30 and a potty location mark 58 .
- one theme may be associated with one line of weakness 30 and the other theme may be associated with the other line of weakness 31 or a potty location mark 58 .
- the decorative graphic theme may be established by a plurality of graphics 60 as described above, or a single graphic.
- the decorative graphic theme may be established with one large graphic that makes the mat 20 appear to look like a baseball or a large flower.
- the set of first graphics and the set of second graphics 54 and 56 that provide the reference marks 50 and 52 may advantageously be related to the unifying theme of the decorative graphics 60 . Therefore, in such situations where the decorative graphics 60 have a unifying theme as described above, the first and second graphics 54 and 56 may also be part of the theme.

Abstract
A disposable mat defining a longitudinal direction, a lateral direction, and at least one edge. The disposable mat may include at least one line of weakness that is configured to allow the separation of a removable portion from the disposable mat. The mat may be configured to be used as a toilet or potty mat. Further, the mat may be configured to assist with toilet training.
Description
- The present invention relates to mats, desirably disposable non-slip mats such as disposable toilet or potty training mats that have a removable portion and a holding mechanism configured to increase the resistance of the article to movement.
- Protective toilet or potty mats are often useful in situations where a person, particularly a child, is being toilet trained, or in a circumstance where maintaining a sanitary environment is of particular importance, such as in a hospital or in an elder care environment. It is generally desirable in such situations to protect the area surrounding the toilet or potty chair from bodily exudates, such as urine, which may be present. As such, a mat that isolates the immediate area around the toilet or potty chair is desired. Moreover, in a situation where such an article is used in connection with a child being trained, it is desired that such an article encourages and reinforces toilet and potty use.
- Attempts have been made to provide mats to address at least some of these needs. In certain circumstances, reusable mats or pads have been employed by caregivers to provide a clean and sanitary toileting environment. Nonetheless, this has not always been entirely satisfactory since reusable pads may allow liquid runoff, which in turn could lead to conditions that require frequent cleaning of the mat and the toileting area.
- Moreover, existing options, when placed on a tile, linoleum or other smooth surface, may not always provide a stable and sure toileting location. Further, due typically to manufacturing considerations, the shape of available mats or pads are such that they may not easily be placed about the majority of the base of a toilet, but instead may be placed down adjacent the front portion of the toilet only.
- Further, in training situations, available mats or pads have not always been fully responsive to the desire to create a positive and supportive training environment. That is, existing mats or pads may not remind a child as to where they may suitably orient themselves with respect to the potty or toilet. In addition, existing options may not provide a positive or even fun environment in which to train.
- Accordingly, despite attempts made to provide appropriate toilet or potty mats, there remains a need for disposable mats that are suited for use in a toileting environment. That is, there remains a need for disposable mats that provide a secure, non-slip area, and are capable of fitting closely about the base of a toilet. Further, there remains a need in certain instances to provide these features while reinforcing the training process.
- In response to the problems and difficulties discussed above, a new distinctive disposable mat has been discovered. In one aspect the present invention concerns a disposable mat defining a longitudinal direction, a lateral direction and at least one edge. The disposable mat includes a first face, a second face opposite the first face, and at least one line of weakness. The at least one line of weakness is configured to allow the separation of a removable portion from the disposable mat. The mat also includes a holding mechanism configured to increase the resistance of the mat to movement when the first face of the mat is placed upon a planar surface.
- In another aspect, the present invention concerns a disposable mat defining a longitudinal direction, a lateral direction, a pair of side edges that are parallel to the longitudinal direction and a pair of end edges that are parallel to the lateral direction. The disposable mat includes an operatively liquid impermeable first face, an absorbent second face opposite said first face, and at least one line of weakness. The at least one line of weakness is configured to allow the removal of a portion of the disposable mat. The mat also includes a holding mechanism that is configured to increase the resistance of the mat to movement when the first face of the mat is placed upon a planar surface, and a pair of first reference marks located on the second face. The pair of first reference marks is configured to indicate where the feet of the user should be placed when the user is toileting.
- In yet another aspect, the present invention concerns a disposable mat defining a longitudinal direction, a lateral direction, and at least one edge. The disposable mat includes a first face and a second face opposite the first face and at least one decorative graphic located on the second face. The at least one decorative graphic has a decorative graphic theme and the decorative graphic theme is related to the theme of article graphics of a disposable absorbent article.
- Accordingly, the present invention provides a mat that is suitable for use as a toilet or potty mat. In particular, the present invention provides a mat that may assist in toilet training people, especially children.
- It is understood that both the foregoing general description and the following detailed description are exemplary and are intended to provide further explanation of the invention claimed. The accompanying drawings, which are incorporated in and constitute part of this specification, are included to illustrate and provide a further understanding of the mats of the present invention. Together with the description, the drawings serve to explain the various aspects of the invention.
- The present invention will be more fully understood and further advantages will become apparent when reference is made to the following detailed description of the invention and the accompanying drawings wherein like numerals represent like elements. The drawings are merely representative and are not intended to limit the scope of the appended claims.

For example, the present invention is directed to solving the potential problem of providing adequate protection for a substantial portion of the toileting area. Moreover, the present invention is directed to solving the problem of potential slippage of the mat that may result from a slick backing, by providing a secure, non-slip toileting environment. In particular aspects, the present invention may also be directed to solving the possible problems related to the clean up associated with some non-disposable potty mats. In yet other aspects, the present invention may also be directed to solving problems associated with the process of toilet training children.
- As such, the present invention is directed to a disposable article, for example a disposable toilet or potty mat, that is particularly suited for use when toilet training a child or when providing care for the elderly or others that may have incontinence problems. The mat may be configured to resist movement when in place and to have a removable portion such that it may fit closely about the base of a toilet. In addition, the mat of the present invention may be configured to assist in the toilet training process; for example, the mat of the present invention may include reference marks that provide assist the user in orienting themselves when toileting.
- The disposable mats of the present invention will be described in terms of a disposable potty mat, adapted to be used when training children. In particular, the disposable mats will be described in terms of a potty mat that includes a first face, a second face opposite the first face, and at least one line of weakness. Typically, disposable articles are intended for limited use and are not intended to be laundered or otherwise cleaned for reuse. It is understood that the articles of the present invention are equally adaptable for other types of mats such as bed pads, changing pads, surgical drapes, adult incontinent products, feminine care products, items for medical kits, items for first aid kits, personal hygiene products, other personal care or health care garments, and the like. One such changing pad is described in U.S. application Ser. No. 10/370,683 to Rippl et al., the disclosure of which is incorporated herein by reference in a manner that is consistent (not in conflict) herewith.

FIGS. 1, 3 , 4, 5, 7, and 8 representatively illustrate apotty mat 20 of the present invention.FIGS. 2 and 6 representatively illustrate a section view of thepotty mat 20 ofFIGS. 1 and 5 , respectively, along section line A-A. As illustrated inFIGS. 1, 3 , 4, 5, 7 and 8 thepotty mat 20 of the present invention defineslateral direction 26, and alongitudinal direction 28 perpendicular to thelateral direction 26. In addition, thepotty mat 20 defines at least one edge 35, for instance, a pair of end edges 32 that are parallel to thelateral direction 26, and a pair of side edges 34 that are parallel to thelongitudinal direction 28. As representatively illustrated inFIGS. 2 and 6 , the potty mat also includes afirst face 22 and asecond face 24 opposite thefirst face 22. Thepotty mat 20 also includes at least one line of weakness 29 and at least oneremovable portion 36. - In general, the
second face 24 is that part of thepotty mat 20 that would face the user and that the user would orient themselves upon during use, and thefirst face 22 is that part of thepotty mat 20 that is facing the surface upon which thepotty mat 20 is placed during use. As such, the first and second faces 22 and 24 may be provided by one uniform material, or they may be provided by a plurality of layers, coatings, other materials and applications, and the like or combinations thereof that may be used to provide thepotty mat 20 of the present invention. - As representatively illustrated in
FIGS. 1 and 2 , thepotty mat 20 of the present invention may suitably be provided by a single layer of material. Alternatively, thepotty mat 20 of the present invention may be provided by multiple layers of material, as representatively illustrated inFIGS. 5 and 6 . For example thepotty mat 20 may include afirst layer 72 and asecond layer 74 that is substantially coextensive with thefirst layer 72. In such a configuration, thefirst face 22 would be provided at least in part by thefirst layer 72, and likewise, thesecond face 24 would be provided at least in part by thesecond layer 74. - Alternatively, as representatively illustrated in
FIGS. 5 and 6 , thesecond layer 74 may be smaller than thefirst layer 72 in thelateral direction 26, thelongitudinal direction 28, or both. In such a configuration, thefirst face 22 would be provided at least in part by thefirst layer 72, and thesecond face 24 would be provided at least in part by both thesecond layer 74 and thefirst layer 72. Alternatively, thesecond layer 74 may also be configured to be larger than thefirst layer 72 in thelateral direction 26, thelongitudinal direction 28, or both. In such a configuration, thefirst face 22 would be provided at least in part by both thefirst layer 72 and thesecond layer 74, and thesecond face 24 would be provided at least in part by thesecond layer 74. - The
potty mat 20 of the present invention may be various suitable shapes as are well known in the art. For example, prior to the separation of theremovable portion 36, thepotty mat 20 may be rectangular, round, elliptical, trapezoidal, and the like. Suitably, thepotty mat 20 may have a generally rectangular or square shape for ease of manufacturability. - The surface area of the
potty mat 20 is bounded by theperimeter 40 of the potty mat. Theperimeter 40 may be provided by any layer, face, or material that may be attached or otherwise part of themat 20, or combinations thereof. Therefore, for the generally rectangular configuration illustrated inFIGS. 1, 3 , and 5, theperimeter 40 of thepotty mat 20 is established by end and side edges 32 and 34. Likewise, for the generally round configuration illustrated inFIG. 4 , theperimeter 40 of thepotty mat 20 is established by the at least one edge 35. - In particular embodiments of the present invention, the
potty mat 20 may desirably, although not necessarily, include a holding mechanism 68 that is configured to increase the resistance of the potty mat to movement when thefirst face 22 of thepotty mat 20 is placed upon a planar surface, such as the floor surrounding the potty chair or toilet. Such a holding mechanism 68 can reduce the amount of bunching and shifting in thepotty mat 20 during use. In addition, a holding mechanism 68 can help thepotty mat 20 provide a safe and secure surface upon which the user can rely when toileting. This can be especially beneficial when using thepotty mat 20 in connection with training a child, or using thepotty mat 20 to assist with elder care. - The holding mechanism 68 may be provided by any method known in the art. For example, the
potty mat 20 may include at least one weight 70 to help keep it in place once it is placed upon a planar surface. In particular, and as representatively illustrated inFIGS. 5 and 6 , thepotty mat 20 of the present invention may include four weights 70 that are generally located in the corners of themat 20. Thepotty mat 20 may include as many or as few weights 70 as necessary to achieve the desired results. Moreover, the weights 70 may be distributed anywhere within theperimeter 40 of thepotty mat 20. The weights 70 may be provided by any suitable material such as stainless steel, synthetic or natural rubbers, plastics, and the like or combinations thereof as are well known in the art. - Alternatively, the
potty mat 20 may include a holding mechanism that provides a particular static coefficient of friction when thefirst face 22 of themat 20 is placed upon a planar surface. For example, at least a portion of thefirst face 22 of the present invention may suitably be arranged to present a frictional surface and thus provide the holding mechanism 68 for thepotty mat 20. As such, in one aspect, at least a portion of thefirst face 22 of thepotty mat 20 provides a static coefficient of friction of at least 0.5 as defined by the coefficient of friction test defined herein to provide the holding mechanism 68 of the present invention. Alternatively, at least a portion of thefirst face 22 of thepotty mat 20 has a static coefficient of friction of at least −0.7 as defined by the coefficient of friction test defined herein to provide the holding mechanism 68 of the present invention. In another alternative, at least a portion of thefirst face 22 of thepotty mat 20 has a static coefficient of friction of at least 1.5 as defined by the coefficient of friction test defined herein to provide the holding mechanism 68 of the present invention. - Further, in an arrangement as described above, it may be desired that the holding
mechanism 60 maintain a static coefficient of friction below a particular level in order to allow the user or caregiver to more easily adjust thepotty mat 20. Specifically, it may be desirable that at least a portion of thefirst face 22 of thepotty mat 20 providing theholding mechanism 60 have a static coefficient of friction of between 0.5 and 2.0 as defined by the coefficient of friction test defined herein to provide the holding mechanism of the present invention. More desirably, at least a portion of thefirst face 22 of thepotty mat 20 has a static coefficient of friction of between 0.7 and 1.5 as defined by the coefficient of friction test defined herein to provide the holding mechanism 68 of the present invention. - Any suitable material, coating, adhesive, or other additive, or combinations thereof may be used to imbue at least a portion of the
first face 22 with the desired coefficient of friction to provide the holding mechanism 68 of the present invention. For example, in one aspect, the holding mechanism 68 may be provided by an adhesive included on thefirst face 22 that allows themat 20 to be applied and then removed and re-applied repeatedly as necessary during use. Alternatively, the holding mechanism 68 may be provided by a film material that also provides thefirst face 22 of themat 20. One such film is available from Pliant Corporation and is described in greater detail below. - In the various aspects of the present invention, the
potty mat 20 also includes at least one line of weakness 29. For example, as representatively illustrated inFIGS. 1, 3 , 4, 5, 7 and 8 the potty mat includes a first line of weakness 30. The first line of weakness 30 may intersect with at least oneedge 32, 34, or 35 of the potty mat in order to create aremovable portion 36. As such, thepotty mat 20 is configured to allow the separation of theremovable portion 36 from themat 20. Accordingly, the user or caregiver may optionally separate theremovable portion 36 from thepotty mat 20 at the first line of weakness 30 so that themat 20 may be placed about the base of a toilet or potty chair to provide greater protection, particularly on the sides of the toilet or potty chair. - Referring to
FIGS. 1, 3 , 4, 7 and 8, the at least one line of weakness 29 may be substantially continuous and intersects at least oneedge 32, 34, 35 of themat 20 in at least two points. Alternatively, the at least one line of weakness 29 may be relatively discontinuous. In another alternative (not shown) the at least one line of weakness 29 may intersect one edge of themat 32 or 34 at one point and intersect a different edge of themat 32 or 34 at another point. - The at least one line of weakness 29 may be suitably located in the
potty mat 20 in order to allow the separation of theremovable portion 36 from themat 20. For instance, the at least one line of weakness 29 may be located in thefirst face 22, thesecond face 24, or, as representatively illustrated inFIG. 2 , the at least one line of weakness may pass through theentire mat 20 and accordingly be located in both the first andsecond face mat 20 includesdiscrete layers mat 20 may be relatively easy for the user or caregiver to tear, while another layer of themat 20 may be difficult to tear. In such a configuration, the at least one line of weakness 29 may not necessarily be located in the easily tearable layer, but may advantageously be located in the layer that is relatively difficult to tear. - Further the at least one line of weakness 29 may be suitably apparent to the user or the caregiver to facilitate the separation of the
removable portion 36. In certain aspects, the at least one line ofweakness 36 may be adequately apparent as a result of the nature of how the at least one line ofweakness 36 is provided. Alternatively, the at least one line of weakness may be accentuated with bright colors, highlighting, markings, or text. - In one aspect, and as illustrated in
FIGS. 1, 3 , 4, 7 and 8 the at least one line of weakness 29 may be shaped such that upon separating theremovable portion 36, themat 20 includes a pair of laterally spacedextensions 38. Thus, theextensions 38 may be placed along either side of the base of a toilet or about a potty chair in order to provide suitable side coverage in use. In a particular aspect, it may be desirable that the laterally spaced extensions be separated by at least 22 cm in said lateral direction. As such, upon separation of theremovable portion 36, themat 20 of the present invention may easily be fitted about the base of a toilet or potty chair, yet still fit closely enough that adequate protection is provided and the need for additional clean-up is reduced. - Alternatively, the user or caregiver may choose not to separate the
removable portion 36 from thepotty mat 20. In such a situation, a potty chair may be placed in a suitable location on thesecond surface 24 of themat 20. As will be described in greater detail below, thepotty mat 20 may include a potty location mark 58 (representatively illustrated inFIG. 4 ) suggesting a suitable location for a potty chair to be located. Such an arrangement may also be desirable in situations where a toilet is wall-mounted. - The at least one line of weakness 29 of the present invention may be generally linear or curvilinear. As such, the at least one line of weakness 29 may create a
removable portion 36 of various shapes and sizes to accommodate the base of a toilet or potty chair. In the illustrated embodiments, the lines of weakness 30 and 31 are generally curvilinear to createremovable portions 36 that are generally circular or semi-circular in shape. Alternatively, theremovable portions 36 may be elliptical, semi-elliptical, rectilinear, and the like. - In another aspect, as representatively illustrated in
FIG. 5 , the at least one line of weakness may be configured to intersect with itself to create aremovable portion 36. Specifically, the at least one line of weakness 29 may be shaped such that upon separating theremovable portion 36 from themat 20, themat 20 includes an opening within itsperimeter 40. In such an arrangement, themat 20 may optionally provide protection all the way around the potty or toilet. In addition, the line of weakness 30 may be continued from the edge of theremovable portion 36 to anedge 32, 34 or 35 of themat 20 in order to provide a slit (not shown) to ease the use of themat 20 in connection with a toilet. - The opening provided by the
removable portion 36 may be of various shapes and sizes. For example, the opening may be rectangular, circular, elliptical, triangular, and other shapes as are known to those skilled in the art, and combinations thereof. Similarly, the opening may be of differing sizes to accommodate the base of a toilet or a potty chair. Desirably, at least a portion of the opening is at least 9 inches wide to allow the user or caregiver to readily place themat 20 in the toileting area while still providing adequate protection directly around the toilet or potty chair. - In particular aspects, the
potty mat 20 may include multiple lines of weakness. For instance, as representatively illustrated inFIGS. 1 and 4 , thepotty mat 20 may include a first line of weakness 30 and a second line of weakness 31. Optionally, the first line of weakness 30 and the second line of weakness 31 may be located in opposing areas of themat 20. That is, as representatively illustrated inFIGS. 1 and 4 , the first line of weakness 30 may intersect one end edge 32 and the second line of weakness 31 may intersect the opposing end edge 32. Likewise, as representatively illustrated inFIG. 4 , each line of weakness 30 and 31 intersects the at least one edge 35, but in opposing areas of thesecond face 24. Thus, the user or the caregiver has the option of separating one or both of theremovable portions 36. As will be described in greater detail below, such an arrangement may be desirable when the user or caregiver is selecting between various gender specific options that may be provided by thepotty mat 20. - Suitable techniques to provide the line of weakness to allow manual separation of the
removable portion 36 are well known in the art. For example, the line of weakness may be provided by perforations in themat 20, a line of continuous or intermittent ultrasonic bonds, an area of lower basis weight in the material, and the like or combinations thereof. - The various aspects of the
potty mat 20 of the present invention may also include a variety of reference marks 50, 52 on thesecond face 24 of themat 20 that are configured to indicate where the feet of the user should be placed when the user is toileting. Reference marks 50, 52 associated with the present invention may be configured to indicate where the user should place their feet in a number of different ways. For example, and as will be discussed in greater detail below, the reference marks of the present invention may indicate their purpose by their location, the nature of the graphic providing the mark, or combinations thereof. Alternatively, thepotty mat 20 may also include text and other information to direct the user when toileting. - Thus, as representatively illustrated in
FIGS. 3, 4 , 5, 7 and 8 themat 20 may include a pair of first reference marks 50 on thesecond face 24. In addition, and as mentioned above, the potty 20 may also include apotty location mark 58 on thesecond face 24 of themat 20 that is configured to indicate where a potty chair may be suitably placed should the user or caregiver choose to use themat 20 in connection with a potty chair. For example, as representatively illustrated inFIG. 4 , thepotty mat 20 may include apotty location mark 58 as well as at least one line of weakness 29. Thepotty location mark 58 may be any suitable symbol, graphic, text, or combination thereof that may indicate to the user or caregiver where the potty chair should be placed. For example, thepotty location mark 58 may be a silhouette of a potty chair, or may be a potty chair shaped flower, baseball, sun, or other suitable object. It should be noted that thepotty location mark 58 may be located within theremovable portion 36, intersect the at least one line of weakness 29, or may otherwise be located within theperimeter 40 of themat 20. - In a particular aspect, the
potty mat 20 may include a pair of first reference marks 50 located between a pair of opposing lines of weakness, 30 and 31, as representatively illustrated inFIG. 8 . In such an arrangement, the user or caregiver may select whether thepotty mat 20 should be configured to be used while standing and toileting or sitting while toileting. Accordingly, such an embodiment would allow the selection of a gender specific orientation with only a single pair of reference marks 50. For example, the user or caregiver may use the first line of weakness 30 to separate theremovable portion 36 that the first reference marks 50 are pointing at. In such an arrangement, the first reference marks 50 would indicate where the feet of the user should be placed when standing while toileting. Alternatively, the user or caregiver may use the second line of weakness 31 to separate theremovable portion 36 that the first reference marks 50 are pointing away from. In such an arrangement, the first reference marks 50 would indicate where the feet of the user should be placed when sitting while toileting. - In addition, the
mat 20 may also include a pair of second reference marks 52 on thesecond face 22. Similar to the first reference marks 50, the second reference marks 52 may also be configured to indicate where the feet of the user should be placed when the user is toileting. However, the second reference marks 52 may be used to indicate where the feet of the user should be placed when using the toilet or the potty chair differently than when the user is using the potty chair according to the first reference marks 50. That is, the first reference marks 50 may be provided to indicate where the feet of the user should be placed when using the toilet or potty chair while standing. Accordingly, in such an arrangement, the second reference marks 52 may be provided to indicate where the feet of the user should be placed when using the toilet or potty chair while sitting. - The first and second reference marks 50 and 52 may both be associated with the same line of weakness 30 or
potty location mark 58. Alternatively, the first and second reference marks 50 and 52 may be associated with different lines of weakness 30 or potty location marks 58 or combinations thereof. For example, as representatively illustrated inFIG. 4 , the pair of first reference marks 50 may be associated with a first line of weakness 30 and indicate one orientation for a user's feet (in this instance standing), while the pair of second reference marks 52 may be associated with a second line of weakness 31 and indicate a different orientation for a user's feet (in this instance sitting). As such, and as will be described in greater detail below, apotty mat 20 including both first and second reference marks 50 and 52 may optionally have gender specific configurations. - In another alternative, the first and second reference marks 50 and 52 may each be located on the
removable portions 36 that are provided by the first and second lines of weakness 30 and 31. Thus, the user or the caregiver may optionally configure themat 20 for use while sitting or while standing by removing the desiredremovable portion 36, and consequently, the reference marks 50 or 52 that may no longer be required is also removed. For instance, as representatively illustrated inFIG. 7 , if it is desired to configure themat 20 to be used for standing while toileting, theremovable portion 36 may be separated from themat 20 at the first line of weakness 30. As such, the second reference marks 52 are also removed. Likewise, if it is desired to configure themat 20 to be used for sitting while toileting, theremovable portion 36 may be separated from themat 20 at the second line of weakness 31. As such, the first reference marks 50 are also removed. Theabove mat 20 configuration may be helpful in a situation where the toileting process is desired to be as simple as possible, such as when toilet training small children. - The individual objects that make up the pair of reference marks 50 or 52 may each be located a substantially equal distance from the at least one line of weakness 29 or the
potty location mark 58. Therefore, if a pair of reference marks 50 or 52 is provided by a pair of feet, each foot may be located a substantially equal distance from the at least one line of weakness or thepotty location mark 58. As used herein in connection with the reference marks 50 and 52, a “substantially equal distance” means the distances are within 5 cm of each other. Thus, in the above example, if one foot in a pair of reference marks were 10 cm away, the other foot should be between 5 cm and 15 cm away so the pair of reference marks 50 or 52 is located a substantially equal distance from the at least one line of weakness 29 or thepotty location mark 58. - For example, the pair of first reference marks 50 each may be located a first substantially equal distance from the at least one line of weakness 29 or the
potty location mark 58. In a particular aspect the distance between the at least one line of weakness 29 or thepotty location mark 58 and the pair of first reference marks 50 may be a first substantiallyequal distance 84 of between 5 cm and 22 cm. In another aspect, the distance between the at least one line of weakness 29 or thepotty location mark 58 and the pair of second reference marks 52 may be a second substantiallyequal distance 86 of between 12 cm and 30 cm. This distance may be measured by measuring the shortest linear distance between the reference marks and the line of weakness or potty location mark, as shown inFIGS. 3, 4 and 5. - The reference marks 50 and 52 of the present invention may be depicted by graphics located on the
second surface 24 of themat 20. The graphics may be any suitable figure, object or symbol. For greatest effectiveness, the nature of the graphic should be such that the user associates the graphic with where they should stand. For example, the graphic can be a pair of foot prints, animal paws or hooves, or the soles of shoes or boots or other footware, and the like or combinations thereof. In addition, the graphics for a pair of reference marks 50 or 52 may be two different objects. Alternatively, the graphics for a pair of reference marks 50 or 52 may be substantially similar (i.e. a left and right foot or a left and right shoe), or identical. As representatively illustrated inFIGS. 3, 4 and 5, the mat includes a pair of first reference marks 50 provided by a set of first graphics 54. In the illustrated embodiments, the set of first graphics 54 are a pair of feet or other foot ware, thus making the set of first graphics 54 providing the first reference marks 50 substantially similar. Likewise, as representatively illustrated inFIGS. 4 and 7 , the mat includes a pair of second reference marks 52 provided by a set ofsecond graphics 56. In the illustrated embodiment, the set ofsecond graphics 56 are a pair of feet, thus making the second graphics providing the second reference marks 52 substantially similar. - In a particular aspect, the set of first graphics and set of
second graphics 54 and 56 for the first and second reference marks 50 and 52 may be substantially similar (i.e. a pair of left and right feet or shoes, but they may be pointing in different directions) or identical. Alternatively, the set of first graphics and set ofsecond graphics 54 and 56 for the first and second reference marks 50 and 52 may be different to further distinguish them from each other. For instance, the first andsecond graphics 54 and 56 may be different in order to make the first andsecond graphics 54 and 56 gender specific. Such an arrangement may be particularly useful to assist with toilet training children. In particular, thereference mark 50 or 52 that indicates where the user should place their feet when standing may be provided bygraphics 54 or 56 that are generally of interest to young boys. Accordingly, thereference mark 50 or 52 that indicates where the user should place their feet when sitting may be provided bygraphics 54 or 56 that are generally of interest to young girls. This arrangement may be used regardless of whether the first and second reference marks 50 and 52 are associated with the same line of weakness 30 orpotty location mark 58 or not. - The
mat 20 may also include at least one decorative graphic 60 located on thesecond face 24 of themat 20. As with the set of first graphics and the set ofsecond graphics 54 and 56, thedecorative graphics 60 may be any suitable figure, object, or symbol. For instance, as representatively illustrated inFIG. 3 , the decorative graphics include planets, rockets, and other objects directed to “space.” Similarly, as representatively illustrated inFIG. 5 , thedecorative graphics 60 include fish, boats, and other nautical objects. Thedecorative graphics 60 may be related or unrelated. In particular aspects, and as described above, thedecorative graphics 60 may collectively have a unifying decorative graphic theme (i.e. “space” and “nautical”). The themes may enhance the aesthetic qualities of the mat, including largely ornamental graphics, or if using themat 20 in connection with toilet training a child, the graphics can be attractive to a child, gender specific, or relate to a character or story popular with children. In a particular aspect, thegraphics 60 in one area of themat 20 may be of one theme, while thegraphics 60 in another area of themat 20 may be of a different theme. For instance, as representatively illustrated inFIG. 4 , thegraphics 60 on one portion of themat 20 are directed to a nature theme while thegraphics 60 on another portion of themat 20 are directed to a sporting theme. This arrangement may be useful where there is a first and second line of weakness 30 and 31 or a line of weakness 30 and apotty location mark 58. As such, one theme may be associated with one line of weakness 30 and the other theme may be associated with the other line of weakness 31 or apotty location mark 58. - It may also be noted that the decorative graphic theme may be established by a plurality of
graphics 60 as described above, or a single graphic. For example, in a circumstance where thepotty mat 20 is round, the decorative graphic theme may be established with one large graphic that makes themat 20 appear to look like a baseball or a large flower. - In certain aspects, the set of first graphics and the set of
second graphics 54 and 56 that provide the reference marks 50 and 52 may advantageously be related to the unifying theme of thedecorative graphics 60. Therefore, in such situations where thedecorative graphics 60 have a unifying theme as described above, the first andsecond graphics 54 and 56 may also be part of the theme. For example, as representatively illustrated inFIG. 3 , the theme of thedecorative graphics 60 is space related, and the first graphic 54 is a pair of space boot prints. Similarly, as representatively illustrated inFIG. 5 , the theme of thedecorative graphics 60 is nautical, and the first graphic 54 is a pair of flippers. Alternatively, it may be desirable to distinguish thegraphics 54 and 56 that provide the reference marks 50 and 52 from the unifying theme of thedecorative graphics 60 in order to make the marks more visible to the user. In another aspect, thepotty location mark 58 may also be related to the theme of thedecorative graphics 60, or alternatively, may be different than the theme of thedecorative graphics 60 in order to distinguish the suggested location of the potty chair for the user or caregiver. - In other aspects, the theme of the
decorative graphics 60 of themat 20 may advantageously match at least one of the graphical themes that may be present on a disposable absorbent article. Such absorbent articles are well known in the art and include children's training pants, diapers, adult incontinence articles, and the like. For example,FIG. 7 representatively illustrates a disposableabsorbent article 80, specifically a child's training pant, havingarticle graphics 82. Thearticle graphics 82 generally have a “space” theme. Accordingly, it may be advantageous, particularly when training, to have the wearer of the article associate the article with thepotty mat 20. As such, the theme of thedecorative graphics 60 may be related to the theme of thearticle graphics 82. For example, as mentioned above,FIG. 3 representatively illustrates amat 20 havinggraphics 60 that matches the theme of thearticle graphics 82 on the article illustrated inFIG. 7 . One example of an absorbent article having graphics is described in U.S. Pat. No. 6,297,424 to Olson et al., the disclosure of which is hereby incorporated by reference in a manner that is consistent (i.e. not in conflict) herewith. - The
graphics graphics - Numerous materials may be used to provide the
potty mat 20 having some or all of the characteristics described above. Thepotty mat 20 may be provided by various natural or synthetic woven or nonwoven materials, film layers, and other materials or combinations thereof. For example, one suitable material for thepotty mat 20 of the present invention is a nonwoven laminate material composed of pre-formed 33.9 grams per square meter (gsm) wettable spunbond and a 15.24 micron catalloy film layer sandwiching a 50.84 gsm wettable meltblown layer. This material is available as CONTROL* Plus Absorbent Fenestration Reinforcement Fabric from Kimberly Clark Corporation, a company having offices in Neenah, Wis. Such a laminate material may be used alone or with coatings or adhesives to provide asingle layer mat 20 as representatively illustrated inFIGS. 1 and 2 . - Alternatively, as mentioned above, the
potty mat 20 may be provided by multiple layers of discrete material. For example, as representatively illustrated inFIGS. 5 and 6 , thepotty mat 20 may include afirst layer 72 disposed toward thefirst face 22 of the potty mat and asecond layer 74 located adjacent thefirst layer 72. Thus, in certain aspects, thefirst layer 72 may be arranged to provide at least a portion of thefirst face 22 of thepotty mat 20, and thesecond layer 74 may be arranged to provide at least a portion of thesecond face 24 of thepotty mat 20. - In a multiple layer configuration, the
layers second layer 74 may be joined directly to thefirst layer 72 by an adhesive. Such adhesives may be applied by spraying, slot coating, or other methods, and combinations thereof. In one aspect, thelayers second layer 74 may be joined directly to the film layer by ultrasonic bonding, pressure bonding, heat welds, stitching, mechanical attachment, or other methods known in the art, and combinations thereof. - The
first face 22 may either be liquid permeable or liquid impermeable. In certain aspects, it may be advantageous for thefirst face 22 to be operatively liquid impermeable. As such, thefirst face 22 may be provided at least in part by thin plastic film or other flexible liquid-impermeable material. Further, thefirst face 22 may optionally be composed of a micro-porous “breathable” material which permits vapors to escape from thefirst face 22 while still preventing liquid exudates from passing through. - In a particular aspect, the first face of the
potty mat 20 may be provided by afirst layer 72 that is a liquid impermeable polyethylene film having a thickness of 15.24 microns and a basis weight of about 45 gsm. The polyethylene film may further include a blend of resins to provide the potty mat with the desired coefficient of friction. Suitable resins include, but are not limited to, vinyl acetates, methyl acrylates, and polyolefin plastomers. One such film may be obtained from Pliant Corporation having an office in Chippewa Falls, Wis. under the designation of film XC2-22-1645.3. Alternatively, the first face may be provided by a substantially liquid permeable material that is treated to be substantially liquid impermeable. Such treatments are well known in the art, and include, but are not limited to SCOTCH-GARD PROTECTOR treatment. - The
second face 24 of thepotty mat 20 may be more or less absorbent than thefirst face 22. Alternatively, thesecond face 24 may have absorbent properties that are substantially similar to thefirst face 22. In certain aspects, it may be advantageous for at least a portion of thesecond face 24 to be relatively more absorbent than thefirst face 22. For example, thefirst face 22 may be absorbent at least adjacent to the at least one line of weakness 29. Alternatively, the entiresecond face 24 may be absorbent. - As such, the
second face 24 may be provided at least in part by an absorbentsecond layer 74. The absorbentsecond layer 74 may be formed from any suitable absorbent material such as natural or synthetic fibers, cellulose, foams, superabsorbent particles, and combinations thereof. In a particular embodiment, the absorbent structure can be a unitary or single-ply fibrous web having a laminate-like structure. This structure may consist of a soft, absorbent central core region of relatively low fiber concentration sandwiched between two strong, abrasion resistant surface regions of high fiber concentration. The surface regions may include bonding material to provide strength to the web. Desirably, this bonding material may be elastomeric. The relatively low fiber concentration within the central core region provides space to increase the absorbency of the web. Within the central core region and extending entirely through the web are networks of fibers that generally connect the two surface regions together without the use of bonding material. The bonding material in at least one surface region may be disposed of in a fine, spaced-apart pattern, and the bonded portions in that surface region may be finely creped to soften them. Such an absorbent structure is described as a double recreped fibrous web (DRC) and is further disclosed in U.S. Pat. No. 5,674,590 issued Oct. 7, 1997 to Anderson et al., the disclosure of which is hereby incorporated by reference. In a particular aspect, the absorbent layer may be a DRC having a basis weight of between 80 gsm and 90 gsm, and more particularly about 86 gsm. - Advantageously, in the arrangements where the
second face 24 is configured to be absorbent, it suitably provides a certain level of absorbent capacity to thepotty mat 20. In one aspect, thesecond face 24 may provide an absorbent capacity of at least 0.05 grams/cm2 as determined by the absorbent capacity test set forth herein. In another aspect, thesecond face 24 may provide an absorbent capacity of at least 0.07 grams/cm2 as determined by the absorbent capacity test set forth herein. Alternatively, thesecond face 24 may provide an absorbent capacity of between 0.05 grams/cm2 and 1.2 grams/cm2. - The different aspects of the present invention advantageously provide a
potty mat 20 that has at least one line of weakness that is configured to allow the separation of a removable portion from the potty mat. As such, the potty mat may be effectively tailored for use with a toilet or for use with a potty chair. The present invention may also advantageously include reference marks that are configured to indicate where the feet of the user should be placed when the user is toileting. Thus, thepotty mat 20 may be used to assist in the toilet training process, as well as providing a more sanitary toileting environment. Moreover, the training benefit may be enhanced by the optional use of at least one decorative graphic having a decorative graphic theme. Various other graphics that may be present on the potty mat or on absorbent articles worn by the user may relate to the decorative graphic theme thereby providing a positive and even fun toilet training environment. Thus, the present invention provides a potty mat that may be readily placed about the base of a toilet and provides a clean, secure, and positive toileting environment to the user. - Suitable techniques for demonstrating the improved qualities of the present invention are set forth below in the “Testing” section of the present disclosure.
- Test Methods
- For the tests described below, the following example was used:
- A mat including the following:
- A 15.24 micron film layer having a basis weight of about 45 gsm available from Pliant Corporation (Chippewa Falls, Wis.) under the designation of film XC2-22-1645.3. An 86 (gsm) DRC absorbent layer available from Kimberly-Clark Corporation (Neenah, Wis.).
- The film layer and the absorbent layer were joined using Airflex 426 binder applied at a basis weight of about 1.6 gsm. The adhesive is available from Air Products and Chemicals, Inc., a company having an office in Allentown, Pa.
- Coefficient of Friction (COF)
- This test is used to measure the static COF of the
first face 22 of the mat. The procedure determines the initial (static) friction of a material when beginning to slide over another material. A sled, which has the test specimen attached, is pulled over a platen (table) which has a representative surface material (the metal surface of the instrument) or a representative surface material attached. The test specimen and material on the platen are in surface-to-surface contact with each other. The COF is defined as the measure of the relative difficulty when the surface of one material starts to slide over an adjoining surface of either itself or of another material. The static COF represents the maximum COF values obtained during the first inch (2.54 cm) of specimen travel distance at a testing rate of 15.25 cm/min. - The following apparatus and material are required: Coefficient of Friction tester TMI Model 32-90 and Testing-Sled B with foam 200±5.0 grams both obtained from Testing Machines, Inc., Islanda, N.Y.
- The test specimens are prepared as follows: Care must be taken in handling the specimens. The test surface must be kept free of all dust, lint, fingerprints, or any foreign matter that might change the surface characteristic of the specimen. Identify and mark the machine direction on the test side of the specimen. Cut the sled specimen from the specimen 120±1 mm in the machine direction longitudinal direction and 67±1 mm in the lateral direction.
- The specimens are tested as follows: Conduct the testing in an atmosphere of 230±2° C. and 50±2% relative humidity. Condition all specimens a minimum of 24 hours prior to testing. Calibrate the COF tester according the manufacturer's directions. Set the travel distance to 15 cm and set the travel speed to 15.25 cm/min. Set the COF tester display to read grams and zero the display. The specimen with the
outer surface 24 exposed is mounted to the test sled using clamps on the sled. The longer dimension is engaged in the clamps which are at either end of the sled. Ensure the surfaces of the test specimen and test bed materials are not contaminated during mounting. The sled is positioned very lightly and gently on the surface of the platen to prevent any unnatural bond from developing between the specimen and the surface of the platen. Start the test by pressing the TEST key on the COF tester. - The results are calculated and displayed by the COF tester. The COF tester records the “STATIC” value for the highest instantaneous coefficient of friction value obtained to begin the movement between the surfaces within the first inch of pull. The COF tester also records the “KINETIC” value obtained from the average of the values obtained during the 60 seconds of the test (15 cm travel distance). The calculation for “STATIC” coefficient of friction is obtained by the tester using the following equation: μs=As/B, where μs=the static coefficient of friction value, As=the maximum initial gram value obtained within the first inch of movement, and B=sled weight of about 200 grams. Three specimens of each sample should be tested and the results should be averaged.
- Absorbent Capacity
- As used herein, “absorbent capacity” is the grams of distilled water per unit area retained by the mat. Absorbent capacity is determined by conditioning the test samples in a standard laboratory atmosphere of 23±1° C. and 50±2% RH for at least 24 hours prior to testing the sample. All testing is conducted under the standard laboratory conditions. Cut a 10.1 cm by 10.1 cm sample from the specimen. Weigh the specimen to the nearest 0.01 gram and place in a bath of distilled water. Allow the specimen to soak for 3 minutes (±5 seconds) ensuring an excess amount of water is present in the bath to completely saturate the specimen. After 3 minutes, remove the specimen and hang it from a clamp (such as a office binder clip, a suitable example is a 1.9 cm wide by 0.95 cm capacity binder clip; part no. BTM00251 available from BT Office Products, Milwaukee Wis.) in a diamond shape so that one corner is lower than the rest of the specimen. Allow the specimen to drain for 3 minutes (±5 seconds). After 3 minutes, remove the specimen from the clamp and weigh to the nearest 0.01 gram. Calculate the absorbent capacity (grams per 10.1 cm by 10.1 cm sample) by subtracting the dry specimen weight from the saturated specimen weight. Three specimens of each sample should be tested, and the results should be averaged.
