HISTORY OF THE INVENTION
[001] Although disposable absorbent garments offer a convenient way to control bedwetting, many enuretic families are not satisfied with these products as they are viewed as diaper-like items by the user who wishes to wear a conventional underwear. As such, many improvements have been made to disposable absorbent clothing to make it more similar to underwear. For example, gender-specific graphic signs have been added and softer non-woven materials have been used. However, many potential users are still looking for a product that looks and feels more similar to conventional underwear but is still able to help control urinary incontinence. Therefore, there still remains a need for pants that are similar to underwear but that still help to contain emitted urine. SUMMARY OF THE INVENTION
[002] In one aspect, the present invention provides a discrete absorbent insert. The absorbent insert includes a first sheet, a second sheet in frontal relationship with the first sheet, and an absorbent core positioned between the first sheet and the second sheet. The absorbent core defines a core perimeter and the first sheet and second sheet extend beyond the core perimeter and are joined to form a perimeter seal. The absorbent insert has a dry thickness of at least 4mm, a minimum width of less than 120mm, a maximum width of at least 170mm, an absorbent capacity of at least 600g, and a length of 375mm to 475mm. The discrete absorbent insert is substantially devoid of fluid impermeable materials.
[003] In some applications of this aspect, the discrete absorbent insert includes a first input material positioned between the first sheet and the absorbent core. In some applications, the absorbent insert includes a second input material positioned between the absorbent core and the second sheet.
[004] In some applications of this aspect, the absorbent core defines a longitudinal direction, a first end section, a second end section, and a center section. The center section is positioned between the first end section and the second end section. The first end section, the second end section, and the center section define equal lengths in the longitudinal direction. The first end section defines a maximum width of at least 120 mm, the center section defines a maximum width of less than 100 mm, and the second end section defines a maximum width of at least 120 mm.
[005] In some applications of this aspect, the absorbent insert has an input rate for a first urine output through the first sheet of less than 30 seconds and an input rate for a first urine output through the second sheet of less than 30 seconds .
[006] In some applications of this aspect, the discrete absorbent insert is folded and packaged individually in a package. In some applications, the discrete absorbent insert is folded a first time so that a first portion of the first sheet is in frontal relationship with a second portion of the first sheet and is folded a second time so that a third portion of the first sheet is in a front relationship with a first portion of the second sheet.
[007] In some applications of this aspect, the first sheet is joined to the second sheet with the perimeter seal with adhesive and the perimeter seal has a width of at least 20 mm. In some applications, the first sheet is joined to the second sheet in the perimeter seal with an ultrasonic bond and the perimeter seal is at least 10 mm wide.
[008] In another aspect, the present invention provides a discrete absorbent insert containing a first sheet, a second sheet in front relationship with the first sheet, and an absorbent core positioned between the first sheet and the second sheet. The absorbent core defines a core perimeter and the first sheet and second sheet extend beyond the core perimeter and are joined to form a perimeter seal. The absorbent insert also includes an entry layer positioned between the first sheet and the absorbent core. The first sheet and second sheet are fluid permeable, strands of yarn joined after extrusion composed of synthetic polymer filaments. The absorbent insert includes an absorbent capacity of at least 600 g and the discrete absorbent insert is devoid of a fluid impervious layer.
[009] In some applications of this aspect, the absorbent core is at least 40% superabsorbent. In some applications, the absorbent core has at least 15 grams of "fluff" cellulose and at least 15 grams of superabsorbent. In some applications, the input layer has a basis weight of at least 85 gsm.
[010] In some applications of this aspect, the discrete absorbent insert is folded a first time so that a first portion of the first sheet is in front relationship with a second portion of the first sheet and is folded a second time so that a third portion of the first sheet is in front relationship with a first portion of the second sheet.
[011] In some applications of this aspect, the discrete absorbent insert is devoid of fasteners and is devoid of containment tabs.
[012] In some applications of this aspect, the absorbent core defines a length of the absorbent core as measured in the longitudinal direction, a first end section, a second end section, and a center section. The center section is positioned between the first end section and the second end section. The first end section, the second end section, and the center section define equal lengths in the longitudinal direction and together define the overall length of the absorbent core, and wherein the first end section defines a maximum width of at least 135 mm, the center section defines a maximum width of less than 90 mm, and the second end section defines a maximum width of at least 135 mm.
[013] In another aspect, the present invention provides a discrete absorbent insert containing a first sheet, a second sheet in front relationship with the first sheet, and an absorbent core positioned between the first sheet and the second sheet. The absorbent core defines a core perimeter and the first sheet and second sheet extend beyond the core perimeter and are joined to form a perimeter seal. The absorbent core is at least 40% superabsorbent and an entry layer positioned between the first sheet and the absorbent core. The input layer has a basis weight of at least 100 gsm. The first sheet and second sheet are fluid permeable, strands of yarn joined after extrusion composed of synthetic polymer filaments. The discrete absorbent insert is devoid of a fluid impervious layer. The absorbent core also defines a longitudinal direction, a first end section, a second end section and a center section. The center section is positioned between the first end section and the second end section. The first end section defines a maximum width of at least 135 mm, the center section defines a maximum width of less than 90 mm, and the second end section defines a maximum width of at least 135 mm.
[014] In some applications of this aspect, the discrete absorbent insert is folded a first time so that a first portion of the first sheet is in front relationship with a second portion of the first sheet and is folded a second time so that a third portion of the first sheet is in front relationship with a first portion of the second sheet. The discreet double-folded absorbent insert is individually positioned within a package.
[015] In some applications of this aspect, the absorbent core has at least 17 grams of "fluff" cellulose and at least 17 grams of superabsorbent.
[016] In some applications of this aspect, the absorbent core defines a length of the absorbent core as measured in the longitudinal direction. The first end section defines a first end section length that is 25 to 30% of the length of the absorbent core. The second end section defines a second end section length that is 25 to 30% of the length of the absorbent core. The center section defines a center section length that is 40 to 50% of the length of the absorbent core. The first end section and the second end section have a variable width at different points along the longitudinal direction, and the center section has a consistent width at different points along the longitudinal direction.

[049] The containment pants of the present invention provide a durable outer structure and an inner pocket to contain a disposable absorbent insert. In some applications, the containment pants are provided in a permanently closed condition. As used herein, the term "permanently closed" refers to a pants that are provided in a condition that is adapted to be just put on or taken off like a conventional underwear and differs from pants that have resealable fasteners and diapers that are provided in an open condition and which include fasteners to secure tissues around the user's body. Suitable restraint pants are also described in the US patent application. xx/xxx, xxx, entitled "Containment Pant", filed July 12, 2012, and with procedural registration number 64816460US01, the entirety of which is incorporated herein by reference.
[050] An example containment pants of the present invention is representatively illustrated in Figures 1-3. Specifically, Figure 1 shows a side perspective view of a containment pants 10 containing a frame 12 and a strap 14 secured within the frame 12. Frame 12 defines a waist opening 16 and a pair of leg openings 18. Structure 12 also defines a front waist region 20, a rear waist region 22, and a genital region 28. The genital region 28 lies between the front waist region 20 and the rear waist region 22. The containment pants 10 of Figure 1 is shown in Figures 2 and 3 with frame 12 partially cut away to better illustrate the internal elements. Figure 2 representatively illustrates a side perspective view with the frame 12 partially cut away to better illustrate the positioning and construction of the strip 14 on the back of the containment pants 10. Figure 3 representatively illustrates a side view in perspective with the frame 12 partially cut away to better illustrate the construction and positioning of the strip 14 on the front of the containment pants 10. The containment pants 10 define a longitudinal direction 48 and a transverse direction 50 as illustrated in Figure 1. The longitudinal direction 48 extends. extends from the front waist region 20 through the genital region 28 and into the rear waist region 22. The transverse direction 50 is perpendicular to the longitudinal direction 48. The frame 12 includes an outer layer 36 and may further include a waist elastic , leg elastic, or both. Referring again to Figure 1, structure 12 is illustrated with a waist elastic 38 secured to outer layer 36 and encircling waist opening 16 and leg elastics 40 secured to outer layer 36 and encircling each of the leg openings 18 .
[051] Another example of the containment pants of the present invention is representatively illustrated in Figures 6-8. Specifically, Figure 6 shows a side perspective view of a containment pants 11 containing a frame 12 and a strap 14 secured within the frame 12. The frame 12 defines a waist opening 16 and a pair of leg openings 18. Structure 12 also defines a front waist region 20, a rear waist region 22, and a genital region 28. The genital region 28 is located between the front waist region 20 and the rear waist region 22. The containment pants 11 of Figure 6 is shown in Figures 7 and 8 with frame 12 partially cut away to better illustrate the internal elements. Figure 7 representatively illustrates a side perspective view with the frame 12 partially cut away to better illustrate the positioning and construction of the strip 14 on the back of the containment pants 11. Figure 8 representatively illustrates a side view in perspective with the frame 12 partially cut away to better illustrate the construction and positioning of the strip 14 on the front of the containment pants 11. The containment pants 11 also define a longitudinal direction 48 and a transverse direction 50 as illustrated in Figure 6. Frame 12 includes a outer layer 37 and may further include a waist band 38 or leg bands 40, or both. Referring again to the Figure In Figure 6, structure 12 is illustrated with a waist elastic 38 secured to the outer layer 37 and surrounding the waist opening 16 and leg elastics 40 secured to the outer layer 37 and surrounding each of the leg openings. 18.
[052] In many applications, the outer layer can be manufactured from a single piece of material or from several pieces of material. In some applications, the outer layer can be made from two or more pieces of material. For example, Figure 4 is a top view of the component parts of the outer layer 36 of Figures 1-3. The component parts include a front member 21 and a rear member 23. In another example, Figure 9 is a top view of the component parts of the outer layer 37 of Figures 6-8. The component parts include a front component 24 and a rear component 31.
[053] In many applications, the component parts of the outer layer can be joined in any suitable way. For example, front member 21 may be joined to back member 23 in a genital seam 29 as shown in Figure 5. Figure 5 is a top view of the component parts of outer layer 36 partially joined. In another example, front member 24 may be joined to back member 31 in a genital seam 29 as shown in Figure 10. Figure 10 is a top view of the component parts of outer layer 37 partially joined. In addition, one or both side edges of the back component can be joined to one or both side edges of the front member at one or more side seams to define a three-dimensional part. Specifically, referring to Figure 5, the side edges 25 of the back member 23 can be joined to the side edges 27 of the front member 21 at the side seams 26 to define the leg openings 18 and waist opening 16 of the containment pants 10 as illustrated in Figure 1. Similarly, the side edges 25 of the back member 31 of Figure 10 can be joined to the side edges 27 of the front member 24 at the side seams 26 to define the leg openings 18 and waist opening 16 of the containment pants 11 as illustrated. in Figure 6.
[054] In various applications, side seams and/or seams in the genital area can be formed using any suitable means such as ultrasonic bonding, thermal bonding, adhesive bonding, pressure bonding, sewing, similar and their combinations . In some applications, the side seams and/or the seam in the genital area can be formed by sewing the component parts of the outer layer using yarn and any suitable stitch pattern or combination of patterns. In some applications, side seams and/or seams in the genital area can be formed using a strip seam.
[055] In some applications, the present invention provides a first outer layer containing a first general shape and a second outer layer containing a second general shape that is different from the first general shape. In some applications, the first shape of the outer layer can be adapted to the anatomy of a male user. In some applications, the second shape of the outer layer can be adapted to the anatomy of a female user. Customizing the first outer layer and/or the second outer layer is believed to be beneficial to allow for gender differences in anatomy, body shape and underwear style preferences. For example, the outer layer 36 illustrated in Figure 1 is shaped and styled suitable for men. In comparison, the outer layer 37 illustrated in Figure 6 is shaped and styled suitable for women. In some applications, the front members 21 may include protrusions 98 to partially define the leg openings as shown in Figures 4 and 5. In addition, the rear member 23 may also include protrusions 98 to partially define the leg openings as shown in Figures 4 and 5. Figures 4 and 5. In many applications, the front component may have an area that is similar in size to the area of the rear component as illustrated in Figures 9 and 10. In other applications, the front component may have an area that is significantly less than the area of the rear component, as illustrated in Figures 4 and 5.
[056] In various applications, the elastic waistband can surround at least 50, 60, 70, 80 or 90% of the respective waist opening. In some applications, the waist elastic 38 may encircle 100% of the waist opening 16 as representatively illustrated in Figures 1 and 6. In various applications, the leg elastic may encircle at least 50, 60, 70, 80 or 90% of one or both leg openings. In some applications, the leg elastic 40 may surround 100% of both leg openings 18 representatively illustrated in Figures 1 and 6.
[057] In various applications, the waist band and/or the leg band may be in full frontal relationship with the outer layer (not shown). In some applications, the waist elastic and/or leg elastic may be partially or completely wrapped within the outer layer (not shown). In other applications, the waist elastic and/or the leg elastic may be supported relative to the outer layer. As used herein, the term "backed" refers to a waist elastic and/or leg elastic having less than 100% front relationship to the outer layer and extending beyond an outer edge of the outer layer. For example, again with reference to Figures 2 and 7, the waist elastics 38 are supported as they extend beyond the outer edge 46 of the respective outer layers 36 and 37. Likewise, the leg elastics 40 are also supported as they extend beyond the outer edge 46 of respective outer layers 36 and 37.
[058] In various applications, the waist elastic and/or leg elastic can be joined with the outer layer using any suitable means such as ultrasound joining, thermal joining, adhesive joining, pressure joining, sewing and the like and their combinations. In some applications, the elastic waistband and/or the elasticized legband can be sewn to the outer layer using yarn and any suitable stitch pattern or combination of patterns. For example, Figures 1-3 and Figures 6-8 representatively illustrate the waist elastic 38 joined to the respective outer layers 36 and 37 in a stitched seam of the waist elastic 39 and the leg elastics 40 joined to the respective outer layers 36 and 37 at the stitched seams of leg elastic 41. In some applications, the waist elastic and/or leg elastic can be sewn to the outer layer using a cover stitch.
[059] Within frame 12 is strip 14, which includes a fluid impermeable base sheet 30 and at least one containment tab 32 joined to base sheet 30 to create a fluid impermeable pouch 34. The impermeable pouch The fluid 34 is adapted to house a removable absorbent insert and contain fluid until it can be taken into the absorbent insert. The fluid impermeable pouch 34 is collapsible and is designed to conform and seal against the wearer's body.
[060] In some applications, strip 14 may further include a first transition, a second transition, or both. The first transition and second transition are believed to be beneficial in that they allow the fluid impermeable pouch to be joined within the structure without significantly reducing the extension and retraction properties of the outer layer and/or the elastic waistband. In addition, the first transition and second transition are believed to be beneficial as they allow movement of the fluid impermeable bag from front to back within the structure. This freedom of movement is believed to allow the fluid impervious bag to adjust after putting on the restraint pants and during use.
[061] Referring again to Figures 2 and 7, the strip 14 is illustrated with a second transition 42 joined to the rear waist region 22 of the containment pants. Similarly, in Figures 3 and 8, strap 14 is illustrated with a first transition 44 joined to the front waist region 20 of the containment pants. Alternatively, in any of the applications described herein, the second transition may be joined to the front waist region and the first transition may be joined to the rear waist region. In many applications, the first transition, the second transition, or both, can be one or more discrete pieces of material joined between the pocket and the frame. In other applications, the first transition, the second transition, or both, may be an integral part of the pocket or may be an integral part of the outer layer or any suitable portion of the structure.
[062] For example, Figure 3 illustrates the first transition 44 as an integral part of the outer layer components and Figure 2 illustrates the second transition 42 as a discrete piece of material. In this application, the first transition 44 is constructed from multiple portions of the outer layer 36. As can be seen in Figures 4 and 5, the first transition 44 is constructed from a first portion 44A, a second portion 44B and a third portion 44C. The first portion 44A and the second portion 44B are integral parts of the outer layer back component 23 while the third portion 44C is integral with the outer layer front component 21. When the outer layer is constructed, the first portion 44A and the second portion 44B are joined to the third portion 44C as illustrated by the arrows in Figure 5. The fully constructed first transition 44 is then folded along the fold lines 33 of Figure 5 to define the first transition 44 as illustrated in Figure 3.
[063] In another example, Figure 8 also illustrates the first transition 44 as an integral part of the outer layer components and Figure 7 illustrates the second transition 42 as a discrete piece of material. In this application, the first transition 44 is constructed from a single portion of the outer layer 37. As seen in the Figures In Figures 9 and 10, the first transition 44 is constructed from a portion of the front component 24 of the outer layer. . When the outer layer is constructed, first transition 44 is then folded along fold line 33 of Figure 10 to define first transition 44 as illustrated in Figure 8.
[064] In many applications, a strap and a fluid impermeable bag can be constructed in any suitable way. For example, an exemplary fluid impermeable strap and pouch may include a containment tab, a base sheet, a first transition and a second transition. Referring now to Figure 11, a top view of the component parts of an example pouch and strip are representatively illustrated. A fully constructed pouch 68 fabricated from the component parts of Figure 11 is representatively illustrated in Figure 12. A fully constructed strip fabricated from the component parts of Figure 11 is representatively illustrated in Figure 13. A cross-sectional view of the strip 52 of Figure 13 taken from the above. along the AA line is representatively illustrated in Figure 14.
[065] Now referring to Figure 11, the component parts include a containment tab 54, a base sheet 56, a first transition 58, and a second transition 60. The containment tab 54 defines a proximal portion 62 and a portion distal 64. The proximal portion 62 of the containment tab 54 is joined to the base sheet 56 to create a containment tab seal 66 and define a fluid impermeable pouch 68 as illustrated in Figure 12. In some applications, the containment tabs they can further include one or more rubber bands. For example, as illustrated in Figure 14, the distal portion 64 of the containment tab 54 further includes a containment tab elastic 70.
[066] In various applications, the fluid impermeable bag 68 of Figure 12 can be incorporated into any suitable strap and/or structure using integrated transitions, discrete transitions or combinations thereof. In various applications, the fluid impermeable pouch 68 of Figure 12 may be incorporated into any suitable strap and/or structure using only one transition joined to the front waist region, only one transition joined to the back waist region, or neither. In Figure 13 The fluid impermeable pouch 68 of Figure 12 is joined to first transition 58 and second transition 60 to define strip 52. Referring now to Figures 11-13, first transition 58 defines a first edge 82 and a second edge 84. Similarly, second transition 60 defines a first edge 90 and a second edge 92. Base sheet 56 defines a first edge 86 and second edge 88. First edge 86 of base sheet 56 is joined to second edge 84 of first transition 58 to define a first seam 72. Similarly, second edge 88 of base sheet 56 is joined to first edge 90 of second transition 60 to define a second seam 74.
[067] In various applications, the strip 52 of Figure 13 can be joined to any suitable structure to form a containment pants. In various applications, the strap 52 can be joined to a frame such that the first transition is located in the front waist region or the rear waist region of the frame and the second transition is located in the opposite region of the frame. For example, now referring to Figures 15 and 16, an example containment pants 53 containing a frame 51 and the strap 52 of Figure 13 is representatively illustrated. Figure 15 is a side perspective view of the containment pants 53 with the frame 51 partially cut away to illustrate the attachment of the strap 52 to the rear waist region 22. Specifically, the second transition 60 is joined to the rear waist region 22 of the framework 51 at a rear seam of strap 43. Figure 16 is a side perspective view of the containment pants 53 with frame 51 partially cut away to illustrate the attachment of strap 52 to the front waist region 20. Specifically, first transition 58 is joined to the front waist region 20 of frame 51 at a front seam of strap 45.
[068] In some applications, a strip and a fluid impermeable pouch may be constructed with a first containment tab, a second containment tab, a base sheet, a first transition and a second transition. For example, referring now to Figure 17, a top view of the component parts of another example pouch and strap are representatively illustrated. A fully constructed pouch 118 fabricated from some of the component parts of Figure 17 is representatively illustrated in Figure 18. A fully constructed strip 102 fabricated from the component parts of Figure 17 is representatively illustrated in Figure 19. A cross-sectional view of the strip 102 of Figure 19 taken along line BB is representatively illustrated in Figure 20.
[069] The component parts include a first lateral containment tab 104, a second lateral containment tab 105, a base sheet 106, a first transition 108 and a second transition 110. The first lateral containment tab 104 and the second lateral containment tab lateral containment 105 each defines a proximal portion 112 and a distal portion 114. The first transition 108 defines a first edge 132 and a second edge 134. Similarly, the second transition 110 defines a first edge 140 and a second edge 142. The base sheet 106 defines a first edge 136 and a second edge 138. The first edge 136 of the base sheet 106 is folded along a first fold line 144 to define a first end containment tab 148 as illustrated in Figure 18. Similarly, the second edge 138 of the base sheet 106 is folded along a second fold line 146 to define a second end containment tab 150 as illustrated in Figure 18. The portion of the base sheet 106 proximate the first fold line 144 is joined to the second edge 134 of the first transition 108 to define a first seam 122 as illustrated in Figure 19. Similarly, the portion of the base sheet 106 proximate the second fold line 146 is joined to the first edge 140 of the second transition 110 to define a second seam 124 as illustrated in Figure 19.
[070] In many applications, the side restraint tabs can be curved cut or straight cut. For example, the first lateral containment tab 104 and the second lateral containment tab 105 of Figure 17 are illustrated as having a curved cut. Similarly, the first lateral containment tab 330 and the second lateral containment tab 332 of Figure 28 also illustrate a curved section. In contrast, containment tab 54 of Figure 11 is an example of a straight-cut tab. While not intended to be bound by theory, it is believed that the curved-cut containment tabs facilitate a closer alignment to the wearer's natural body curvature. Therefore, it is believed that a more comfortable and better fit can be obtained.
[071] The proximal portions 112 of each of the side containment tabs 104 and 105 are joined to the base sheet 106 and/or the first end containment tab 148 and/or the second end containment tab 150 to form seals of containment tab 116 and partially define a fluid impermeable pouch 118 as illustrated in Figure 18. In various applications, one or both of the end tabs may be positioned between one or both of the containment tabs and the base sheet. In other applications, one or both of the confinement tabs may be positioned between one or both of the end apertures and the base sheet. For example, in some applications, both end tabs can be positioned between both the containment tabs and the base sheet as shown in Figure 18. In other applications (not shown), both containment tabs can be positioned between them. the end flaps and the base sheet.
[072] In various applications, the end flap may also include an end flap seal 117. The end flap seal 117 may join the first side containment tab 104 and/or the second side containment tab 105 to the first end containment tab 148 and/or the second end containment tab 150 and/or the base sheet 106 to define the fluid impermeable pouch 118 together with the containment tab seals 116. In various applications, the region of overlap 119 between the side containment tabs 104 and 105 and the end containment tabs 148 and 150 can be joined by any suitable manner to define a completely fluid impermeable pouch 118. For example, in some applications, the tabs of lateral containment 104 and 105 can be joined to end containment tabs 148 and 150 at the overlapping regions 119 by adhesive bonding, stitching, ultrasonic bonding, thermal bonding, pressure bonding and the like and combinations thereof. For example, the distal portions 114 of the first side containment tab 104 and the second side containment tab 105 may be completely joined to the end containment tabs 148 and 150 at the overlapping regions 119 to ensure that the pouch 118 is completely impermeable to fluids.
[073] In various applications, any or all of the side containment tabs and/or the end containment tabs may further include one or more elastics. For example, the distal portions 114 of the lateral containment tabs 104 and 105 may further include the elastic of the containment tab 120 as illustrated in Figure 20.
[074] In some applications, the first end containment tab and/or the second end containment tab may further include an insert enclosure that limits the depth to which the absorbent insert can be inserted. For example, the second end containment tab 150 of Figure 18 is illustrated with an insert boundary 147. In this application, the insert boundary 147 is illustrated as an ultrasonic joint between the second end containment tab 150 and the base sheet 106. In various applications, the insert boundaries can be any suitable length or width and can be positioned to any suitable depth within the first end containment pocket and/or the second end containment pocket. In some applications, the insert boundary may extend from one containment tab seal to the other containment tab seal (not shown). In other applications, the insert enclosure 147 may terminate before one or both of the containment tab 116 seals and thereby allow liquid within the second end containment pocket 150 to flow around the insert enclosure 147 and into the interior. of a reservoir 145. In effect, this configuration provides greater volume to contain emitted urine while still providing a conveniently sized pocket for retaining the absorbent insert.
[075] In various applications, the fluid impermeable bag 118 of Figure 18 can be incorporated into any suitable strip and/or structure using integrated transitions, discrete transitions or combinations thereof. In various applications, the fluid impermeable pouch 118 of Figure 18 may be incorporated into any suitable strap and/or structure using only one transition joined to the front waist region, only one transition joined to the back waist region, or neither. In the illustrated application, the fluid impermeable pouch 118 of Figure 18 is joined to the first transition 108 and the second transition 110 to define the strip 102 of Figure 19.
[076] In various applications, the strip 102 of Figure 19 can be joined to any suitable structure to form a containment pants. In various applications, the strip 102 can be joined to a frame such that the first transition is located in the front waist region or the rear waist region of the frame and the second transition is located in the opposite region of the frame. For example, now referring to the Figures In Figures 21 and 22, an example of containment pants 103 containing a frame 101 and strap 102 is representatively illustrated. Figure 21 is a side perspective view of the containment pants 103 with the frame 101 partially cut away to illustrate the attachment of the strap 102 to the rear waist region 22. Specifically, the second transition 110 is joined to the rear waist region 22 of the frame 101 at a rear strap seam 43. Figure 22 is a side perspective view of the containment pants 103 with the frame 101 partially cut away to illustrate the attachment of the strap 102 to the front waist region 20. Specifically, the first transition 108 is joined to the front waist region 20 of frame 101 at a seam of front strap 45.
[077] In another application, a strip and a fluid impermeable bag can be constructed with a base sheet, a first transition, and a second transition. For example, referring now to the Figure In Figure 23, a top view of the component parts of another example of the pouch and the strip are representatively illustrated. A fully constructed pouch 206 fabricated from some of the component parts of Figure 23 is representatively illustrated in Figure 24. A fully constructed strip 152 fabricated from the component parts of Figure 23 is representatively illustrated in Figure 25. The component parts include a base sheet 154, a first transition 156; and a second transition 158. The base sheet 154 includes a first arm 160, a second arm 162, a third arm 164, and a fourth arm 166. The base sheet 154 defines an absorbent facing surface 168 and a surface facing the structure 170.
[078] Referring now to Figures 23 and 24, the first arm 160 and the second arm 162 are bent toward the absorbent facing surface 168 of the base sheet 154 in the direction indicated by arrows 172. A distal portion 174 of the first arm 160 is joined to a distal portion 176 of second arm 162 to define a first connecting splice 178. Similarly, third arm 164 and fourth arm 166 are bent toward the absorbent facing surface 168 of the sheet. base 154 in the direction indicated by arrows 180. A distal portion 182 of the third arm 164 is joined to a distal portion 184 of the fourth arm 166 to define a second connecting splice 186. An inner portion 188 of the first arm 160 is joined to a first portion 190 of base sheet 154 to define a portion of a first containment seam 194. Similarly, an inner portion 192 of second arm 162 is joined to first portion 190 of base sheet 154 to define the remainder of the first. the containment splice 194. An inner portion 196 of the third arm 164 is joined to a second portion 198 of the base sheet 154 to define a portion of a second containment splice 200. Similarly, an inner portion 202 of the fourth arm 166 is joined to the second portion 198 of the base sheet 154 to define the remainder of the second containment seam 200.
[079] By folding the first arm 160 and the second arm 162 in the direction indicated by arrows 172, the side edges204 of the base sheet 154 tend to fold in the direction of the surface facing back to the absorber 168 of the base sheet 154. Similarly, by bending the third arm 164 and fourth arm 166 in the direction indicated by arrows 180, the side edges 204 of the base sheet 154 tend to bend in the same manner to define the containment tab 205. base 154 is concave to define a fluid impermeable pouch 206 containing containment tab 205 as illustrated in Figure 24.
[080] In various applications, the fluid impermeable bag 206 of Figure 24 can be incorporated into any suitable strip and/or structure using integrated transitions, discrete transitions or combinations thereof. In various applications, the fluid impermeable pouch 206 of Figure 24 may be incorporated into any suitable strap and/or structure using only one transition joined to the front waist region, only one transition joined to the back waist region, or neither. In the illustrated application, the fluid impermeable pouch 206 is joined to the first transition 156 and the second transition 158 to define the strip 152 as illustrated in Figure 25. In this application, the first transition 156 defines a first edge 210 and a second edge 212 and the second transition 158 defines a first edge 214 and a second edge 216. The first portion 190 of the base sheet 154 is joined to the second edge 212 of the first transition 156 to define a first seam 218. Similarly, the second portion 198 of the base sheet 154 is joined to first edge 214 of second transition 158 to define a second seam 220. In some applications, fluid impermeable pouch 206 may define a distal edge and may include one or more elastics. For example, as illustrated in Figure 24, distal edge 208 of pouch 206 further includes an elastic of pouch 209.
[081] In various applications, the strip 152 of Figure 25 can be joined to any suitable structure to form a containment pants. In various applications, strap 152 can be joined to a frame such that the first transition is located in the front waist region or the rear waist region of the frame and the second transition is located in the opposite region of the frame. For example, now referring to the Figures In Figures 26 and 27, an example containment pants 153 containing a frame 151 and strap 152 are representatively illustrated. Figure 26 is a side perspective view of the containment pants 153 with the frame 151 partially cut away to illustrate the attachment of the strap 152 to the rear waist region 22. Specifically, the second transition 158 is joined to the rear waist region 22 of the structure. 151 at a rear seam of strap 43. Figure 27 is a side perspective view of containment pants 153 with frame 151 partially cut away to illustrate attachment of strap 152 to the front region of waist 20. Specifically, first transition 156 is joined to the front waist region 20 of frame 151 at a front seam of strap 45.
[082] In another application, a fluid impermeable pouch may be constructed with a first containment tab, a second containment tab, a third containment tab, a fourth containment tab, and a base sheet. For example, referring now to the Figure In Figure 28, a top view of the component parts of another example of the pouch is representatively illustrated. A fully constructed pouch 346 fabricated from the component parts of Figure 28 is representatively illustrated in Figure 29.
[083] The component parts include a first side containment tab 330, a second side containment tab 332, a first end containment tab 334, a second end containment tab 336, and a base sheet 338. containment 330, 332, 334, and 336 each define a proximal portion 340 and a distal portion 342.
[084] Proximal portions 340 of each of containment tabs 330, 332, 334, and 336 are joined to base sheet 338 to form containment tab seals 344 and define a fluid impermeable pouch 346 as illustrated in Figure 29 In many applications, one or both of the end flaps can be positioned between one or both of the containment flaps and the base sheet. In other applications, one or both of the confinement tabs may be positioned between one or both of the end apertures and the base sheet. For example, in some applications, both end tabs can be positioned between both the containment tabs and the base sheet as shown in Figure 29. In other applications (not shown), both containment tabs can be positioned between them. the end flaps and the base sheet.
[085] In various applications, the overlap region 349 between the side containment tabs 330 and 332 and the end containment tabs 334 and 336 can be joined in any suitable manner to at least partially define the completely fluid impermeable pouch 346. For example, in some applications, side containment tabs 330 and 332 can be joined to end containment tabs 334 and 336 at overlap regions 349 by adhesive bonding, sewing, ultrasonic bonding, thermal bonding, bonding by pressure and the like and combinations thereof. For example, the distal portions 342 of the first lateral containment tab 330 and the second lateral containment tab 332 may be completely joined to the end containment tabs 334 and 336 at the overlap regions 349 to ensure that the pouch 346 is completely impermeable to fluids. In other applications, the distal portions of the first end containment tab and the second end containment tab may be completely joined to the side containment tabs in the overlap region to ensure that the pouch is completely impervious to fluid (not shown).
[086] In various applications, one or more of the containment tabs may further include one or more elastics. For example, the distal portions 342 of the containment tabs 330, 332, 334, and 336 may further include the elastic of the containment tab 345. In various applications, the fluid impermeable pouch 346 of Figure 29 can be incorporated into any suitable strap. and/or structure using integrated transitions, discrete transitions or combinations thereof. In various applications, the fluid impermeable pouch 346 of Figure 29 may be incorporated into any suitable strap and/or structure using only one transition joined to the front waist region, only one transition joined to the back waist region, or neither.
[087] Referring now to Figures In Figures 30 and 31, the fluid impermeable pouch 346 of Figure 29 is joined to a first transition 350 and a second transition 352 to define a strap 348 suspended within an example of containment pants. 354. In many applications, bag 346 can be joined within any suitable structure to form a containment pant. In various applications, pouch 346 can be joined to a frame through a first transition that is located in the front waist region or the rear waist region of the frame and through a second transition that is located in the opposite region of the frame. Figure 30 is a side perspective view of the containment pants 354 with the frame 353 partially cut away to illustrate the attachment of the pouch 346 to the rear waist region 22 through the second transition 352. The second transition 352 is joined to the rear waist region. 22 of frame 353 at a rear seam of strap 43. Figure 31 is a side perspective view of containment pants 354 with frame 353 partially cut away to illustrate the attachment of pouch 346 to the front waist region 20 through first transition 350. In the illustrated application, first transition 350 is a discrete piece of material joined to the front waist region 20 of structure 353 while second transition 352 is a discrete piece of material joined to the rear waist region 22 of structure 353.
[088] In general, any of the containment tabs described herein may include one or more containment tab elastics. The containment tab elastics can be joined to the containment tabs in any suitable configuration using any suitable fastening means. For example, in some applications, the containment tab elastics can be joined with the containment tabs using a mechanical coating, adhesive bonding, thermal bonding, ultrasonic bonding, pressure bonding, sewing or similar process, or combinations thereof. .
[089] In some applications, the elastic of the containment tab may be coated, at least partially, within a channel formed by bending a portion of the containment tab. For example, Figure 14 representatively illustrates a cross-sectional view of the strip 52 of Figure 13 taken along line A-A. In this application, the proximal portion 62 of the containment tab 54 is joined to the base sheet 56 to form the containment tab 66 seals. The distal portion 64 of the containment tab 54 is folded over and joined to itself to form a channel 71. The containment tab elastic 70 is coated within the channel 71 and may be partially secured to the containment tab 54. In other applications, the containment tab elastic may be disposed within the channel but is not secured to the containment tab. containment.
[090] In some applications, the containment tab elastic can be folded over the distal edge of the containment tab. For example, Figure 20 representatively illustrates a cross-sectional view of the strip 102 of Figure 19 taken along line B-B. In this application the proximal portion 112 of the containment tabs 104 and 105 are joined to the base sheet 106 to form containment seals 116. The elastic of the containment tab 120 is folded over the distal edge 121 of the first lateral containment tab 104 and the second side containment tab 105. The elastics of containment tab 120 may be joined to the side containment tabs 104 and 105 by any suitable method, such as by stitching.
[091] In various applications, the attachment of the elastic tab of the containment tab to the containment tab can be adjusted to vary the tension in the containment tab. For example, in some applications, the containment tab elastic can be applied at a uniform tension and selected portions can be softened to provide a containment tab elastic having a variable tension along the length of the containment tab. In some applications, the containment tab elastic may be applied at varying tension to provide a containment tab elastic with variable tension along the length of the containment tab.
[092] In many applications, containment tabs can be integrated into the base sheet. For example, the containment tab 205 illustrated in Figure 24 is integrated with the base sheet 154. In other applications, the containment tabs may be discrete pieces of material that are joined to the base sheet using any suitable method to define at least partially the bag. For example, the containment tab 54 illustrated in Figure 12 is discrete from and joined to the base sheet 56 in the containment tab seal 66. In some applications, one or more containment tabs may be integrated with the base sheet and a or more of the containment tabs may be discrete parts. For example, Figure 18 illustrates the first end containment tab 148 and the second end containment tab 150 being integrated with the base sheet 106 while the first side containment tab 104 and second side containment tab 105 are discrete from and joined to base sheet 106 in containment flap seals 116.
[093] In many applications, the discrete containment tabs can be joined to the base sheet in any suitable way. For example, the containment tabs can be sewn to the base sheet, heat joined, adhesively joined, ultrasound joined, splicing tape, or the like, or combinations thereof. In applications where the pouch is fluid impermeable, the discrete containment tabs are joined to the base sheet to provide a fluid impermeable seal. The fluid-tight seal is believed to prevent leakage from the pouch until the absorbent insert is able to receive the fluids.
[094] In some applications, the fluid-tight seal is created, at least in part, using ultrasonic bonding. Ultrasonic bonding fuses the base sheet material to the containment flap material. Ultrasonic bonding can use any suitable bonding pattern to adjust the seal bond strength. For example, the ultrasound splice pattern can be one or more lines of "broken" splices. For example, in some applications, the splice pattern may include three offset broken splice lines as illustrated in Figure 13. In other applications, the ultrasound splice pattern may include one or more continuous "wave" splice patterns . For example, in some applications, the splice pattern may include a single continuous "wave" splice pattern as illustrated in Figure 18. In other applications, the ultrasound splice pattern may include one or more rows of splices in "spots". For example, in some applications, the splice pattern may include two rows of offset stitch splices as illustrated in Figure 24. Ultrasonic splicing can be performed using an ultrasonic tip and anvil pattern. In some applications, ultrasonic seams can be created through the use of a sonic sewing machine. A suitable machine is offered by "Sonobond" with model number LM920. In many applications, the Sonobond Sonic Sewing Machine can have an output setting of 7.5, an anvil speed of 2, and a tip speed of 2.
[095] It is believed that the use of ultrasonic bonding is beneficial in some applications compared to sewing because no holes are created in the containment flap and therefore the integrity of the bag is preserved. Similarly, it is believed that the use of ultrasonic bonding is beneficial in some applications compared to splicing tape as the containment tabs and/or base sheet may melt at the tape application temperature. of typical splicing. In some applications, the base sheet is made of laminated polyurethane and polyester and the retaining flaps are made of laminated polyurethane and polyester. In these applications, the base sheet and containment tab can be constructed with ultrasonic bonding to create a strong seal without burning through the base sheet or containment tab.
[096] The flap seals collectively define a flap seal perimeter. The portion of the base sheet circumscribed by the perimeter of the flap seal constitutes the base surface of the pouch. For example, with reference now to Figure In Figure 29, containment tabs 330, 332, 334, and 336 are joined to base sheet 338 at tab seals 344 and define a perimeter of tab seal 356. The location on the sheet of base 338 when the perimeter of the tab seal 356 will be formed is shown with a dashed line in Figure 28 for purposes of illustration. In general, the portion of the base sheet 338 circumscribed by the perimeter of the flap seal 356 constitutes the base surface of the pouch 358. The base surface of the pouch 358 defines a base surface length of the pouch 360, a surface width of pouch base 362 and a pouch base surface area 364.
[097] In any of the applications disclosed herein, one or more of the containment tabs may further include an absorbent insert enclosure. The absorbent insert enclosure can be any suitable physical barrier that limits the depth of the absorbent insert within one or more of the containment tabs. In various applications the boundary of the absorbent insert can be a mechanical union between the containment flap and the base sheet. The mechanical bond may be an ultrasound bond, a thermal bond, a sewn bond, a pressure bond, an adhesive bond, or the like, or combinations thereof. For example, referring now to the Figure In Figure 29, the second end containment tab 336 is illustrated with an absorbent insert enclosure 351. In this application, the absorbent insert enclosure 351 is illustrated as an ultrasound abutting joint. the depth of insertion of the absorbent insert into the second end containment tab 336. In another example, the second end containment tab 150 of Figure 18 is illustrated with an insert enclosure 147 which is an ultrasonic joint between the second end containment tab 150 and the base sheet 106.
[098] In applications containing one or more absorbent insert enclosures, the length of the base surface of the pouch and the base surface area of the pouch are defined in part by the seal of the containment flap and in part by the enclosure of the absorbent insert. For example, referring again to Figure 28, the location on the base sheet 338 where the absorbent insert boundary 351 will be formed is shown with a dashed line for purposes of illustration. In applications with the absorbent insert boundary 351, the base surface of the pouch 358 defines a base surface length of the pouch 361 and a base surface area of the pouch 365. In these applications, the length of the base surface of the pouch 361 is defined by end portion 355 of containment flap seal 344 and absorbent insert boundary 351. Similarly, the base surface area of pouch 365 is defined by absorbent insert boundary 351 and side portions 357 of the absorbent insert seal. containment tab 344 to the points where the absorbent insert boundary 351, if extended, crosses the containment tab seal 344.
[099] In applications that include one or more absorbent insert enclosures, the base surface of the pouch may also define a reservoir portion that extends between the absorbent insert enclosure and the containment tab seal under a containment tab. For example, again with reference to Figures In Figure 28 and 29, the base surface of the pouch 358 defines a reservoir portion 359 extending from the absorbent insert enclosure 351 to the end portion 363 of the containment flap seal 344 In another example, now referring to Figure 18, the pouch 118 includes a reservoir portion 145 extending from the absorbent insert enclosure 147 to the end flap seal 117. As discussed above, the insert enclosures may be any suitable length or width and can be positioned to any suitable depth within the first end containment pocket and/or the second end containment pocket. In some applications, the absorbent insert enclosures may terminate before one or both of the containment flap seals and therefore allow fluid to flow into the containment pocket around the absorbent insert enclosure and into the reservoir portion. In various applications, the reservoir portion can have a length of about 50 to 70 mm or about 60 mm.
[100] The base surface of the pocket 358 also defines a first end section 366, a second end section 367, and a center section 368 in the longitudinal direction 48. The center section 368 extends between the first end section 366 and the second end section 367. The first end section 366 defines the first end section width 369 and a first end section length 370. The second end section 367 defines a second end section width 371 and a second end seal length 372. Center section 368 defines a center section width 373 and center section length 374. The first end section length 370 plus the second end section length 372 plus the center section length 374 is equal to the length of the base surface of the bag. The widths of the various sections are measured in the transverse direction 50 and the lengths of the various sections are measured in the longitudinal direction 48. The dimensions of the base surface of the pouch are measured in a pouch mounted by tracking around the inner edge of the perimeter of the flap seal. with a pen, cutting the retaining flaps and the elastic of the bag, and placing the bag on a level floor. If no flap seal is present, the base surface of the pouch is defined relative to the distal edge of the containment flap. Specifically, in these applications, the base surface of the bag is defined by the 30 mm position of the distal edge of the containment flap.
[101] In an application adapted for children weighing 60 to 120 pounds, who can be characterized as large or extra large, the length of the base surface of the bag can be 380 to 500 mm, or 410 to 470 mm or about 440 mm. In an application adapted for children weighing between 38 and 65 pounds, who can be characterized as small and/or medium, the length of the base surface of the bag can be 350 to 450 mm, 375 to 425 mm, or about 400 mm . In some of these applications, the base surface of the pouch may also include a reservoir having a length of 50 to 70 mm, or about 60 mm.
[102] In various applications, the first length of the end section may equal the length of the center section which may be equal to the second length of the end section. In other applications, the first end section length may be the same as the second end section length and the center section length may be different. For example, the first length of the end section can be about 35% of the length of the base surface of the pouch, the second length of the end section can be about 35% of the length of the base surface of the pouch, and the length of the center section can be about 30% of the length of the base surface of the bag. In another example, the first length of the end section can be about 30% of the length of the base surface of the pouch, the second length of the end section can be about 30% of the length of the base surface of the pouch, and the length of the center section can be about 40% of the length of the base surface of the pouch.
[103] In many applications, the base surface of the bag can have a width that varies at different points along the longitudinal direction. For example, as illustrated in Figure In Figure 28, the base surface of the pocket 358 has a variable width at different points along the longitudinal direction. In this application, the first end section 366 and the second end section 368 have a maximum width that is greater than the maximum width of the center section 367. For example, the first end section and the second end section can have a width maximum of about 145 to 195 mm, about 160 to 180 mm or about 171 mm. In these applications, the center section can have a maximum width of about 60 to 100, about 70 to 90 mm, or about 82 mm.
[104] In various applications, the first end section, second end section, and/or center section may have a variable width at different points along the longitudinal direction or may have a consistent width at different points along the length. longitudinal direction. In some applications, the first end section and second end section may have variable width at different points along the longitudinal direction and the center section may have a consistent width at different points along the longitudinal direction as illustrated in Figure 28. In some applications, the first end section and the second end section may have a width ranging from 171 mm maximum to 82 mm minimum. In these applications, the center section can have a consistent width of about 82 mm.
[105] In some applications, the base surface of the pouch defines a first reference width 376 measuring in 1/8 of the length of the base surface of the pouch, a second reference width 377 measuring in / the length of the base surface of the pouch. pouch and a third reference width 378 measured in 7/8 of the length of the base surface of the pouch. In some applications, the first reference width 376 may be equal to the third reference width 378 and the second reference width 377 may be smaller than the first and third reference widths 376 and 378. In some applications, the second reference width 377 may be less than 50%, 60%, 70%, or 80% of the first reference width 376 and/or the third reference width 378. In some applications, the second reference width 377 may be about 48% of the first reference width 376 and third reference width 378.
[106] In many applications, the base surface area of the bag can be any suitable value. For example, in child-friendly applications weighing 60 to 120 pounds, the base surface area of the bag can be around 55,000 mm2. In applications adapted for children weighing between 38 and 65 pounds, the base surface area of the bag can be approximately 47700 mm2.
[107] In many applications, the base surface of the pouch can define any suitable shape. For example, the base surface of the pouch may be symmetrical about the transverse centerline or it may be asymmetrical about the transverse centerline. In many applications, the base surface of the bag can be shaped like a "dog bone", "hourglass" shape, "T" shape, rectangular shape or similar.
[108] In various applications, the pouches of the present invention can be joined to one or more transitions in any suitable manner. For example, pouches can be joined to transitions by stitching, ultrasonic joining, thermal joining, adhesive joining, splicing tape, and the like, and combinations thereof. In some applications, transitions can be joined to the bags by stitching, using any suitable stitch or combination of stitches. For example, in some applications, transitions can be secured to bags using a single needle stitch followed by an upper stitch.
[109] In some applications, bags can be constructed so that extra material is available to secure the transitions without violating the integrity of the fluid-impermeable bag. For example, in some applications, the containment tab may be joined to the base sheet in the containment tab seal. The containment tab seal may be positioned so that a portion of the containment tab material and/or base sheet material is available to be secured to the first or second transition while maintaining the integrity of the fluid impermeable pouch.
[110] In some applications, the strap is minimally attached to the frame to maximize fit and natural movement of the frame. In some applications, the strip is attached to the structure through the first transition and/or the second transition. In various applications, the first transition may be joined to the front waist region at the front seam of the strap and the second transition may be joined to the rear waist region at the rear seam of the strap. In other applications, the first transition may be joined to the rear waist region at the back seam of the strap and the second transition may be joined to the front waist region at the front seam of the strap. The first transition and/or the second transition may be joined to any suitable portion of the front waist region and/or the back waist region. For example, the first transition and/or the second transition may be joined at the elastic waistband seam at the front waist region and/or at the rear waist region. Additionally or alternatively, the first transition and/or the second transition may be joined to the outer layer at the front waist region and/or at the second rear waist region. In some applications, the first transition and/or the second transition may be integrated into the framework. In these applications, the full transition is linked to the exchange using any suitable method, including those described herein. In some applications, the first transition and/or second transition may be integrated with the outer layer of the structure. For example, Figures Figure 8 and 10 representatively illustrate a transition that is integrated into the outer layer of the structure. In these applications, the integral transition is part of the outer layer material and is a distinct projection from the outer layer material.
[111] In some of the applications, the strap can be attached to the frame in the front waist region, the back waist region, and the genital region. The strip can be attached to the frame in the genital region by any suitable means. For example, the strip can be sewn, ultrasound joined, thermal joined, adhesive joined, pressure joined, and the like, and combinations thereof. In some applications, the strap can be attached to the frame in the genital region via one or more tabs. The flaps can be discrete pieces of material that are joined to the strap pocket and also to the frame using any suitable means. For example, in some applications, the flaps can be discrete pieces of material that are ultrasonically joined to the strap pocket and sewn with thread to the frame. In many applications, the flaps can be attached to the frames using any suitable stitching or combinations thereof. For example, in some applications, flaps can be joined to the frame using zigzag stitches.
[112] Referring now to the Figures In Figures 26 and 27, the strip 152 is joined to the genital region 28 of the frame 151 by discrete tabs 100 (only one is visible). Specifically, tabs 100 are joined to strip 152 through a first tab splice 149. Similarly, tabs 100 are joined to frame 151 through a second tab splice 199. ultrasound to preserve fluid-tight bag 206. Flap second splice 199 is a sewn-thread joint.
[113] In some applications, the tabs may be an integral part of the strap. For example, the tabs can be an integral part of one or more of the containment tabs. In these applications, the strip can be joined to the frame by joining the tabs to the frame using any suitable means. For example, in Figures 11-16, containment tab 54 includes securing tabs 67 that extend from proximal portion 62 of containment tab 54. As shown in Figures 15 and 16, strap 52 is joined to genital region 28 of frame 51 by fastening tabs 67 (only one is visible) and tab splices 199 (only one is visible).
[114] In another example, the tab may be an integral part of the base material. In these applications, the strip can be joined to the frame by joining the tabs to the frame using any suitable means. In other applications, the tabs can be an integral part of the base material and the containment tabs. For example, in the Figures In Figures 17-22, the side restraint tabs 104 and 105 both include an integral securing tab 94. Similarly, the base sheet 106 includes a pair of integral securing tabs 96. The strip 102 can be attached to a frame using, in part, attachment tabs 94 and/or 96. For example, Figures 21 and 22 representatively illustrate strip 102 attached to frame 101 in the genital region 28 using attachment tabs 94 and 96 .
[115] In some applications, the straps of the present invention define a perimeter and are joined to the frame around the perimeter. For example, referring again to the Figure In Figure 19, strip 102 defines a perimeter 115 that includes portions of the first transition 108, the second transition 110, and the pocket 118. In various applications, the strips of the present invention can be joined to structures in around any suitable percentage of the perimeter. For example, in some applications, the strip can be joined to the frame in less than 30%, less than 25%, less than 20% and less than 15% of the perimeter. In some applications, the strap can be attached to the structure about 22% of the perimeter. In some applications, the attachment tabs have a length in the longitudinal direction that is less than 75 mm, less than 50 mm, or less than 25 mm.
[116] The outer layer can be fabricated from any suitable material or a combination of materials. In various applications, the outer layers of the present invention can be manufactured from cotton, cotton blends, nylon, nylon blends, polyester, polyester blends, rayon, rayon blends, spandex and the like and combinations thereof. In some applications, the outer layers can be a mixture of nylon and spandex. For example, the outer layers can be 80% nylon and 20% spandex material. In some applications, the outer layer may be a cotton fabric blended with spandex. For example, the outer layer can be a cotton fabric containing 12% to 25%, 15% to 22% or about 20% spandex. Thus, in some applications, the outer layer may be 80% cotton and 20% spandex. In other applications, the outer layer may be a polyester fabric blended with spandex. In these applications, the polyester fabric can be 8% to 16%, 10% to 15% or about 14% spandex. Thus, in some applications, the outer layer may be 86% polyester and 14% spandex.
[117] In some applications, the outer layer is capable of extending in the transverse direction to at least 250% (ie, a 4-inch piece of relaxed material that is stretched to 8 inches is 100% and if stretched to 14 inches is 25%. Furthermore, in some applications, the outer layer is adapted to have sufficient tractive force in the transverse direction to hold the pants firmly against the body both on initial placement and after the urine is emitted. In some applications, the outer layer is adapted to have sufficient tractive force in the transverse direction in the extension range from about 100% to about 250%.
[118] The tensile strength of various materials can be determined using the Strip Tensile Test described below. This test measures load in grams and elongation in %. In this test, two tongs, each with two jaws with each jaw having one face in contact with the sample, hold the material in the same plane, usually vertical, 3 inches apart, and move apart at a specified rate of extension. Values for this test are obtained using a suitable specimen width, a specimen length of 7 inches, a wedge face size of 1 inch high by 3 inches wide, and a constant extension rate of 300 mm/minute. The "Sintech 2" tester, offered by Sintech Corporation, 1001 Sheldon Dr., Cary, N.C. 27513, is suitable for use with this test. The Instron Model(TM), offered by Instron Corporation, 2500 Washington St, Canton, Massachusetts 02021, or a Thwing-Albert INTELLECT II model, offered by Thwing-Albert Instrument Co., 10960 Dutton Rd., Philadelphia, Pa. 19154, can also be used for this test.
[119] The sample outer layer materials were tested using this test method. To measure the transverse direction profile, samples were cut at 3 inches in the longitudinal direction and 7 inches in the transverse direction. To measure the longitudinal direction profile, samples were cut at 3 inches in the transverse direction and 7 inches in the longitudinal direction.
[120] In some applications, the outer layer material has a tensile force (per 3 inches wide) in the transverse direction of about 750 grams force at 100% elongation to about 27,000 grams force at 250 elongation %. In many applications, the outer layer material has a tensile strength (per 3 inches wide) of less than about 1500 grams at 80% elongation in the transverse direction.

In some applications, the outer layer material has a load to the elongation profile in the transverse direction within the range between Profile 1 and Profile 2, within the range between Profile 1 and Profile 3, and within the range between Profile Profile 2 and Profile 3 as summarized in Table 1. In some applications, the outer layer material has a load for the elongation profile in the transverse direction in the Profile 2 values as summarized in Table 1. Table 1: Outer Layer Load (force in grams per 3 inches wide) and Elongation - Transverse Direction


[121] In some applications, the outer layer material is capable of extending in the longitudinal direction up to at least 150%. In some applications, the outer layer is adapted to have sufficient tractive force in the longitudinal direction to hold the pants firmly against the body both on initial placement and after urine emission. In some applications, the outer layer is adapted to have sufficient tensile strength in the longitudinal direction in the extension range from about 80% to about 150%.

In some applications, the waist elastic and/or leg elastic can be made from nylon, spandex, polyester, cotton, rayon, and the like, and combinations thereof. In some applications, the waist band and/or leg band may be a blend of nylon, spandex and polyester. For example, in some applications, the elastic waistband and/or the leg elastic may be 46% nylon, 28% spandex and 26% polyester. In various applications, any suitable yarn can be used to secure the waist elastic to the outer layer material. For example, in some applications, the yarn used to attach the waist band and/or leg elastic to the outer layer may be a polyester yarn.
[123] In some applications, the elastic waistband is capable of extending in the transverse direction to at least 200%. In some applications, the elastic waistband is adapted to have sufficient tractive force in the transverse direction to hold the pants firmly against the body both on initial placement and after urine emission.

In some applications, the leg elastic has a load for the elongation profile between Profile 1 and Profile 2, between Profile 1 and Profile 3, and between Profile 2 and Profile 3 as summarized in Table 4. In some applications, the leg elastic has a load for the elongation profile at the Profile 2 values as summarized in Table 4.

[125] Transition materials can be fabricated from any suitable material or combination of these materials. In various applications, the transition materials of the present invention can be manufactured from cotton, cotton blends, nylon, nylon blends, polyester, polyester blends, rayon, rayon blends, spandex and the like and combinations thereof. In some applications, transition materials can be a mixture of nylon and spandex. For example, transition materials can be 80% nylon and 20% spandex material. In some applications, the transition materials can be a cotton fabric blended with spandex. For example, transition materials can be cotton fabric with 12% to 25%, 15% to 22% or approximately 20% spandex. Thus, in some applications, transition materials can be 80% cotton and 20% spandex. In other applications, the transition materials can be a polyester fabric blended with spandex. In these applications, the polyester fabric can be 8% to 16%, 10% to 15% or about 14% spandex. Thus, in some applications, transition materials can be 86% polyester and 14% spandex.
[126] In some applications, the first transition is made of a first material and the second transition is made of the same first material. In other applications, the first transition is made from a first material and the second transition is made from a second material that is different from the first material. In many applications, the first transition and/or the second transition may be elastically extensible in one or more directions. For example, in some applications, both the first transition and the second transition are elastically extensible in the longitudinal direction and in the transverse direction.
[127] In some applications, transition materials are capable of extending in the transverse direction up to at least 250%. Additionally, in some applications, transition materials are adapted to have sufficient tractive force in the transverse direction to hold the strip firmly against the body, both on initial placement as well as after urine emission. In some applications, transition materials are adapted to have sufficient tractive force in the transverse direction in the range of about 100% to about 250%. The load to elongation profile of transition materials can be determined using the Strip Tensile Test described herein using a 3 inch by 7 inch sample.
[128] In some applications, transition materials have a tractive force in the transverse direction of about 750 grams force per 3 inches wide at 100% elongation to about 27,500 grams force per 3 inches wide at elongation 250%.

[129] In some applications, transition materials are capable of extending in the longitudinal direction up to at least 150%. In some applications, transition materials are adapted to have sufficient tensile strength in the longitudinal direction to hold the strip firmly against the body both at initial placement and after urine emission. In some applications, transition materials are adapted to have sufficient tensile strength in the longitudinal direction in the range of about 80% to about 150%. Thus, in some applications, transition materials have a tensile strength in the longitudinal direction of about 850 grams force per 3 inches wide at 80% elongation to about 21,250 grams force per 3 inches wide at elongation of 150%. In many applications, transition materials have an 80% elongation load in the longitudinal direction of less than about 2,100 grams of force per 3 inches wide. In some applications, transition materials have a 150% elongation load in the longitudinal direction of about 2,000 to about 21,250 grams of force per 3 inches wide. In some applications, transition materials have a load to the elongation profile in the longitudinal direction between Profile 1 and Profile 2, between Profile 1 and Profile 3, and between Profile 2 and Profile 3 as summarized in Table 6 In some applications, transition materials have a load for the elongation profile in the longitudinal direction at Profile 2 values, as summarized in Table 6. Table 6: Transition Material Load (force in grams per 3 inches wide) and Stretching - Longitudinal Direction

[130] In some applications, the first transition defines a first transition width as measured in the transverse direction and a first transition length measured in the longitudinal direction. Similarly, the second transition defines a second transition width as measured in the transverse direction and a second transition length as measured in the longitudinal direction. For example, referring again to the Figure In Figure 17, the first transition 108 defines a first transition width 109 and a first transition length 107. Similarly, the second transition 110 defines a second transition width 111 and a second length 113. In various applications, the first transition width may be the same as the second transition width. In other applications, the first transition width may be smaller than the second transition width. In other applications, the first transition width may be greater than the second transition width. In some applications, the first transition width can be from 100 to 125 mm and the second transition width can be from 170 to 200 mm. In some applications, the first transition width may be about 114 mm and the second transition width may be about 185 mm.
[131] In various applications, the strips of the present invention may include only a first transition or only a second transition. In various applications, the strips of the present invention can include a first transition and a second transition. The first transition or second transition may be positioned in the front waist region or the rear waist region in any of the applications described herein.
[132] In some applications, the base sheet can be fabricated from any suitable material or combination of these materials. In some applications, the base sheet can be made from polyester, polyurethane, polypropylene, polyethylene or the like, or combinations thereof. In some applications, the base sheet may be a polyester fabric laminated with polyurethane. In some applications, the base sheet may be 55% polyester and 45% by weight polyurethane. In some applications, the base sheet may be a polyester fabric laminated with a layer of polyurethane. In many applications, the polyurethane layer can be of any suitable thickness. For example, the polyurethane layer can have a thickness of 1 mm. In many applications, the polyester fabric can be laminated with a layer of polyurethane using any suitable means of joining. For example, the polyurethane layer and the polyester fabric can be laminated together using adhesive bonding, thermal bonding, mechanical bonding and the like and combinations thereof. In some applications, the base sheet may be a polyester fabric adhesively laminated to a 1 mm thick polyurethane layer.
[133] In many applications, the base sheet can be elastically stretchable in one or more directions. For example, in some applications, the base sheet may be elastically extensible in the longitudinal direction and/or in the transverse direction. In other applications, the base sheet may be non-extendable in one or more directions.
[134] In many applications, the base sheet can be of any suitable shape. In some applications the base sheet may be rectangular or non-rectangular. For example, as illustrated in the Figure In Figure 11, the base sheet 56 may have a curvilinear shape where the base sheet defines a first portion 76, a second portion 78, and a third portion 80. In the illustrated embodiment, the first portion 76 has curvilinear side edges and a maximum width that is greater than the maximum width of the second portion 78. Additionally, the third portion 80 has curvilinear side edges and a maximum width that is greater than the maximum width of the second portion 78. The second portion 78 has relatively straight and parallel side edges.
[135] In another example, illustrated in Figure 17, the base sheet 106 may have a curvilinear shape where the base sheet defines a first portion 126, a second portion 128, and a third portion 130. In the illustrated application, the first portion 126 it has curvilinear side edges and a maximum width greater than the maximum width of the second portion 128. Additionally, the third portion 130 has curved side edges and a maximum width that is greater than the maximum width of the second portion 128. The second portion 128 has edges relatively straight and parallel sides except flap 96 which is a distinct projection from base sheet 106.
[136] In another example, illustrated in Figure In Figure 23, the base sheet 154 may have a curvilinear shape where the base sheet defines a first portion 190, a second portion 191, and a third portion 198. In the illustrated application, the first portion 190 has curvilinear side edges and a maximum width that is greater than the maximum width of the second portion 191. Additionally, the third portion 198 has curvilinear side edges and a maximum width that is greater than the maximum width of the second portion 191. The second portion portion 191 has relatively straight and parallel side edges.
[137] In another example, illustrated in Figure In Figure 28, the base sheet 338 may have a curvilinear shape where the base sheet defines a first portion 366, a second portion 367, and a third portion 368. In the illustrated application, the first portion portion 366 has curvilinear side edges and a maximum width that is greater than the maximum width of second portion 367. Additionally, third portion 368 has curvilinear side edges and a maximum width that is greater than the maximum width of second portion 367. portion 367 has relatively straight and parallel side edges.
[138] In some applications, the containment flap material can be made of any suitable material or a combination of these materials. In some applications, the containment flap material can be made of polyester, polyurethane, polypropylene, polyethylene or the like, or combinations thereof. In some applications, the containment flap material may be a polyester fabric laminated with polyurethane. In some applications, the containment flap material may be 55% polyester and 45% polyurethane by weight. In some applications, the material of the containment flap may be a polyester fabric laminated with a layer of polyurethane. In many applications, the polyurethane layer can be of any suitable thickness. For example, the polyurethane layer can have a thickness of 1 mm. In many applications, the polyester fabric can be laminated with a layer of polyurethane using any suitable means of joining. For example, the polyurethane layer and the polyester fabric can be laminated together using adhesive bonding, thermal bonding, mechanical bonding and the like and combinations thereof. In some applications, the material of the containment flap may be a polyester fabric adhesively laminated to a layer of polyurethane having a thickness of 1 mm.
[139] In many applications, the containment tab material can be elastically stretchable in one or more directions. For example, in some applications, the material of the containment flap may be elastically extensible in the longitudinal direction and/or in the transverse direction. In other applications, the containment tab material may be non-extendable in one or more directions.
[140] The elastic of the flap can be formed from any suitable elastic material. As is well known to those skilled in the art, suitable elastic materials include natural rubber, synthetic rubber, or thermoplastic elastomeric polymers, sheets, filaments or tapes. The tab elastic can be stretched and adhered to the containment tab, adhered to a gathered containment tab, or adhered to a containment tab and then stretched or shrunk so that elastic tensile forces are transmitted to the containment tab. In some applications, the elastic on the flap may be made of nylon, spandex, polyester, cotton, rayon and the like, and combinations thereof. In some applications, the elastic on the flap may be a mixture of nylon and spandex. For example, in some applications, the elastic on the flap may be 91% nylon and 9% spandex.
[141] In some applications, the flap elastic may be a low-tension bending elastic. This type of flap elastic is believed to reduce the amount of accumulation and potential points of irritation in the containment flaps. Additionally, this type of flap elastic has a flatter profile and is believed to be more comfortable and provide more surface contact with the wearer's skin for a better seal against the body.
[142] In some applications, the tab elastic can be joined to the containment tab to define a tension of the finished tab. In many applications, the tension of the finished tab can be generally uniform along the entire length of the containment tab. In other applications, the tension of the finished tab may be variable along the length of the containment tab. For example, in some applications, the tension of the finished flap may be higher near the genital region of the restraining pant and may be lower near the front waist region and/or the rear waist region.
[143] Again referring to Figure 28, the first lateral containment tab 330 and the second lateral containment tab 332 define a distal edge 343 and a distal edge length 347. In various applications, the containment tab elastic 345 ( not shown in Figure 28) can be applied at varying tension along the length 347 of tabs 330 and 332. In some applications, the elastic of containment tab 345 can be applied to define a first zone of tension 380, a second zone of tension. tension 381 and a third tension zone 382. In various applications, the elastic tension in the second tension zone 381 can be greater than the elastic tension in the first tension zone 380 and can be greater than the elastic tension in the third tension zone 382. In some applications, the elastic tension in the first tension zone 380 may be the same as the elastic tension in the third tension zone 382.
[144] For example, in one application, the relaxed length of the containment tab 347 may be 390 mm and the elastic of the containment tab 345 may have a relaxed length of 260 mm. The elastic of tab 345 can be applied relaxed (that is, with no elongation) along the first 38 mm of the distal edge 343 to define the first zone of tension 380. The elastic 345 can be applied at an elongation of 89% along the next 276 mm from the distal edge 343 to define the second tension zone 381. In other words, 146 mm of relaxed elastic 345 is stretched to 276 mm and then applied to the distal edge 343 in the second tension zone 381. Finally, the elastic 345 can be applied relaxed along the final 76 mm of distal edge 343 to define the third tension zone 382.
[145] In another application, the relaxed length of the containment tab 347 may be 414 mm and the elastic of the containment tab 345 may have a relaxed length of 273 mm. The elastic of tab 345 can be applied relaxed (that is, with no elongation) along the first 38 mm of the distal edge 343 to define the first tension zone 380. The elastic 345 can be applied at an elongation of 85% along the next 300mm from distal edge 343 to define second tension zone 381. In other words, 162mm of relaxed elastic 345 is stretched to 300mm and then applied to distal edge 343 in second tension zone 381. Finally, elastic 345 can be applied relaxed along the final 76 mm of the distal edge 343 to define the third tension zone 382.
[146] In various applications, containment tab elastic 345 can be applied to the second tension zone 381 with 0 to 200% elongation, 50 to 150% elongation, or about 70 to 90% elongation. In various applications, the elastic of containment tab 345 can be applied to the first tension zone 380 and/or the third tension zone 382 with elongation from 0 to 150%.
[147] In many applications, at least one of the containment pant materials is treated to be more fluid impermeable. For example, in any of the applications described herein, at least one outer layer, waistband, leg elastic, transitions, base sheet, containment flaps, containment flap elastic, and yarn are treated to be more impervious to fluids. In many applications, treatment can include coating the materials in any suitable way using a water resistant treatment that is durable. In some applications, water resistant treatment that is durable may include a polymer coating. In some applications, the base sheet and/or containment flaps may include a fabric laminated with polyurethane where the fabric side of the base sheet is treated with a water resistant treatment that is durable. In some applications, the base sheet and containment flaps can be constructed of a polyester fabric treated with a water resistant treatment that is durable and laminated with a polyurethane sheet. In some applications, the yarn used to join the containment tab elastic to the containment tabs can be treated with a water resistant treatment that is durable.
[148] In some applications, the containment pants of the present invention can be tailored to fit a wide range of sizes. In some applications, an example restraint pants can be adapted for children weighing between 38 and 65 pounds. In some applications, a sample restraint pants can be adapted to fit children weighing between 60 and 120 pounds. To facilitate this wide weight range and maintain a proper fit, the restraint pants of the present invention can be adapted at the waist, hips, and/or legs to extend to about 100% while still providing sufficient tractive force to keep the trousers firmly against the body when putting on, during use and after emission of urine.
[149] To measure the strength-elongation profile of restraint pants, the following apparatus and procedures are used. Apparatus 388 is illustrated in Figures 32-34 and includes a constant rate of extension of the tensile strength tester 390. The tensile strength tester 390 includes a load cell 391, an upper jaw 394, a lower jaw 396, a upper device 398 and lower device 400. A test pant 392 is placed over the upper jaw 394 and the lower jaw 396 in various configurations. The 392 test pants are extended in the 399 direction and the load is measured at various lengths and/or circumferences.
[150] In a first configuration, test pants 392 are positioned on top jaw 394 and bottom jaw 396 as generally illustrated in Figure 32. In this configuration, test pants 392 are positioned to measure the "waist tension of the full pants ". For this test, the upper jaw 394 and the lower jaw 396 have a circumference of 62 mm, a length of 70 mm and are made of a rigid polymeric material having a smooth surface. In this configuration, the upper jaw 394 and the lower jaw 396 are inserted through the waist opening 393 of the test pants 392 only to the extent necessary to encompass the waist elastic 386.
[151] In a second configuration, test pants 392 are positioned on top jaw 394 and bottom jaw 396 as illustrated in Figure 33. In this configuration, test pants 392 are positioned to measure "complete pants hip tension" . For this test, the upper jaw 394 and the lower jaw 396 have a circumference of 78.5 mm, a length of 130 mm, and are made of a rigid polymeric material having a smooth surface. In this configuration, the upper jaw 394 and the lower jaw 396 are inserted through the waist opening 393 of the test pants 392 and extend from the leg openings 395. The portions of the test pants 392 in contact with the upper jaws and lower 394 and 396 are centered on the respective jaw.
[152] In a third configuration, test pants 392 are positioned on top jaw 394 and bottom jaw 396 as illustrated in Figure 34. In this configuration, test pants 392 are positioned to measure "whole pant leg tension" . For this test, the upper jaw 394 and the lower jaw 396 have a circumference of 62 mm, a length of 70 mm and are made of a rigid polymeric material having a smooth surface. In this configuration, the upper jaw 394 and the lower jaw 396 are inserted through the leg opening 395 of the test pants 392 to a depth of 1 inch.
[153] In each of these configurations, the upper jaw 394 and the lower jaw 396 are free to rotate about the axis 397. Prior to testing, the test pants 392 are hung from the upper jaw 394 to account for the force of the test pants and therefore "zeroing" the load cell. The sensor length is selected for the waist opening or leg opening being tested to provide a tension of less than 50 grams before starting the test. The upper clamp 394 and the lower clamp 396 are separated until a tension load of 50 grams is reached and the sensor length is recorded and the elongation percentage is set to zero. The upper clamp 394 and the lower clamp 396 are separated at a head speed of 508 mm/minute and stresses at various sensor lengths are recorded and the elongation percentage is calculated. The circumference of the test pants 392 is calculated as twice the length of the sensor plus / the circumference of the upper jaw 394 plus / the circumference of the upper jaw 396.
[154] The 390 Tensile Strength Tester can be any constant rate tensile strength tester such as the MTS Model Synergie 200 Test Bed Tester that is offered by MTS(R) Systems Corporation of Research Triangle Park, NC, United States of America. The tensile strength tester includes suitable load cells selected so that most peak load values fall within the manufacturer's recommended ranges for the full scale load cell value.
[155] The test procedure is performed under ASTM standard laboratory conditions: atmosphere of 23 +-2 [degrees] C. (73.4+-3.6 [degrees] F.) and 50 +-5% relative humidity. Test pants are measured after balancing under laboratory conditions.
[156] Full pant waist tension, full pant hip tension, full pant leg tension were measured for several different test pants using the test method described above. The results of these tests are summarized below in Tables 7, 8, and 9. The pants included Code A, which is an exemplary pants of the present invention adapted for females in the 38 to 65 pound weight range. Code B is an example pants of the present invention adapted for males in the 38 to 65 pound weight range. Code C is an example pants of the present invention adapted for females in the 60 to 120 pound weight range. Code D is an example pants of the present invention adapted for males in the 60 to 120 pound weight range.
[157] Tables 7, 8, and 9 summarize force in grams (rounded to the nearest gram) over various circles as measured in millimeters. Percent elongation is calculated as the difference between the circumference at a given strain and the circumference at the 50 gram force divided by the circumference at the 50 gram force. Each value represents the average of the 3 pants measurements. This data is graphically represented in Figures 40-45. Table 7: All Pants - Waist Tension

[158] The various containment pants of the present invention are adapted to receive and support a discrete absorbent insert. As used herein, the term "discrete absorbent insert" refers to a self-contained absorbent structure that is adapted for insertion and removal of a pant without tearing, tearing or otherwise damaging the self-contained absorbent structure or pant. In some applications, the absorbent insert has a relatively high capacity adapted for children with urinary incontinence and/or for overnight use. In various applications, the pants of the present invention are devoid of an integrated absorbent core. As used herein, the term "integrated absorbent core" refers to a mass of fibers, particles, foam or the like, or combinations thereof that contain an absorbent capacity of at least 5 g/g and are contained within a pant and are not. adapted for removal of pants without tearing, tearing or otherwise without damage to the pants and/or the absorbent core.
[159] Referring now to the Figures In Figures 35 and 36, a first example absorbent insert 230 is representatively illustrated. Figure 35 is a top view of absorbent insert 230 with portions cut away to better illustrate the underlying structure. Figure 36 is an expanded sectional view of the absorbent insert of Figure 35 taken along line C-C. The absorbent insert 230 defines a longitudinal direction 48, a relatively shorter transverse direction 50, and a thickness direction 49. The transverse direction extends generally perpendicular to the longitudinal direction, and the thickness or "z" direction extends generally perpendicular. both in the longitudinal and in the transverse direction.
[160] The absorbent insert 230 includes a first sheet 232 and a second sheet 234 in front relationship with the first sheet 232. The absorbent insert 230 also includes an absorbent core 236 positioned between the first sheet 232 and the second sheet 234. Figure 37 is a top view of the absorbent core 236 removed from the absorbent insert 230 of Figure 35 to better illustrate the detail. The absorbent core 236 defines a core perimeter 238, and the first sheet 232 and the second sheet 234 extend beyond the perimeter of the core 238, and are joined to form a perimeter seal 240. The outer extent of the first sheet 232 and /or the second sheet 234 defines the perimeter of the absorbent insert 239. The perimeter of the absorbent insert 239 in turn defines an area of the absorbent insert 269.
[161] Absorbent insert 230 defines an absorbent insert width 266 and an absorbent insert length 268. Absorbent insert 230 defines a first end section 270, a second end section 272, and a center section 274 in the longitudinal direction. The center section 274 extends between the first end section 270 and the second end section 272. The first end section 270 defines a first end section width 276 and a first end section length 278. end section 272 defines a second end section width 280 and a second end section length 282. Center section 274 defines a center section width 284 and a center section length 286. The first end section length 278 plus the second length of the end section 282 plus the length of the center section 286 equals the length of the absorbent insert 268. Several sections are measured in the transverse direction 50 and the lengths of the various sections are measured in the longitudinal direction 48.
[162] In an application adapted for use by a child weighing 60 to 120 pounds, the length of the absorbent insert can be 425 to 475 mm, or 430 to 450 mm or about 440 mm. In an application adapted for use by a child weighing 38 to 65 pounds, the length of the absorbent insert can be 375 to 425 mm, 390 to 410 mm, or about 400 mm. In various applications, the first length of the end section may be equal to the length of the center section which may be equal to the second length of the end section. In other applications, the first end section length may be the same as the second end section length and the center section length may be different. For example, the first end section length may be about 35% of the absorbent insert length, the second end section length may be about 35% of the absorbent insert length, and the center section length may be about 30% of the length of the absorbent insert. In another example, the first end section length may be about 30% of the absorbent insert length, the second end section length may be about 30% of the absorbent insert length, and the center section length it can be about 40% of the length of the absorbent insert.
[163] In many applications, the absorbent insert may have a width that varies at different points along the longitudinal direction. For example, as illustrated in Figure In Figure 35, the absorbent insert 230 has a variable width at different points along the longitudinal direction. In this application, the first end section 270 and the second end section 272 have a maximum width that is greater than the maximum width of the center section 274. For example, in some applications, the first end section and the second end section they can have a maximum width of about 160 to 210 mm, 170 to 200 mm, 180 to 190 mm or about 186 mm. In these applications, the center section can have a maximum width of about 90 to 130 mm, about 100 to 120 mm or about 114 mm.
[164] In various applications, the first end section, second end section, and/or center section may have a variable width at different points along the longitudinal direction or may have a consistent width at different points along the length. longitudinal direction. In some applications, the first end section and second end section may have variable width at different points along the longitudinal direction and the center section may have a consistent width at different points along the longitudinal direction as illustrated in Figure 35. In some applications, the first end section and the second end section may have a width ranging from 186 mm maximum to 114 mm minimum. In these applications, the center section can have a consistent width of about 114 mm.
[165] In some applications, the absorbent insert defines a first reference width 316 measured in 1/8 of the length of the absorbent insert 268, a second reference width 317 measured in/of the length of the absorbent insert 268, and a third reference width 318 measured 7/8 of the length of the absorbent insert 268. In some applications, the first reference width 316 may be equal to the third reference width 318 and the second reference width 317 may be less than the first and third reference widths 316 and 318. In some applications, the second reference width 317 may be less than 50%, 60%, 70%, or 80% of the first reference width 316 and/or the third reference width 318. In some applications, the second reference width reference width 317 may be about 60% of the first reference width 316 and the third reference width 318.
[166] The absorbent insert 230 also defines an area of the absorbent insert 269. In various applications, the absorbent insert area can be any suitable value. For example, in applications adapted for use by a child weighing 60 to 120 pounds, the absorbent insert area can be around 65,000 mm2. In applications adapted for use by a child weighing 38 to 65 pounds, the absorbent insert area can be approximately 57,600 mm2.
[167] In many applications, the absorbent insert can define any suitable shape. For example, the absorbent insert can have a shape symmetrical about the transverse centerline as shown in Figure 35 or it can have an asymmetrical shape about the transverse centerline as shown in Figure 38. In various applications, the absorbent inserts can have a rectangle shape, dog bone shape, hourglass shape, T-shaped or similar.
[168] Referring again to Figure In Figure 37, absorbent core 236 defines an absorbent core width 288 and an absorbent core length 289. The absorbent core 236 also defines a first end section 290, a second end section 292 , and a center section 294 in the longitudinal direction 48. The center section 294 extends between the first end section 290 and the second end section 292. The first end section 290 defines a first end section width 296 and a first end section length 298. Second end section 292 defines a second end section width 300 and a second end section length 302. Center section 294 defines a center section width 304 and a center section length 306. The first end section length 298 plus the second end section length 302 plus the center section length 306 is equal to the compress. into the absorbent core 289. The widths of the various sections are measured in the transverse direction 50 and the lengths of the various sections are measured in the longitudinal direction 48.
[169] In an application adapted for use by a child weighing 60 to 120 pounds, the length of the absorbent core can be 350 to 450 mm, 375 to 425 mm, 390 to 410 mm or about 400 mm. In an application adapted for use by a child weighing 38 to 65 pounds, the length of the absorbent core can be 340 to 380 mm, 350 to 370 mm, or about 360 mm. In various applications, the first length of the end section may be equal to the length of the center section which may be equal to the second length of the end section. In other applications, the first end section length may be the same as the second end section length and the center section length may be different. For example, the first length of the end section may be about 25% of the length of the absorbent core, the second length of the end section may be about 25% of the length of the absorbent core, and the length of the center section may be about 50% of the length of the absorbent core. In another example, the first length of the end section can be about 30% of the length of the absorbent core, the second length of the end section can be about 30% of the length of the absorbent core, and the length of the center section it can be about 40% of the length of the absorbent core.
[170] In many applications, the absorbent core may have a width that varies at different points along the longitudinal direction. For example, as illustrated in Figure In Figure 37, the absorbent core 236 has a variable width at different points along the longitudinal direction. In this application, the first end section 290 and the second end section 292 have a maximum width that is greater than the maximum width of the center section 294. For example, in various applications, the first end section and the second end section they can have a maximum width of about 120 to 165 mm, 135 to 150 mm or about 145 mm. In some applications, the maximum width is at least 120 mm, at least 130 mm, at least 140 mm, or at least 145 mm. In these applications, the center section can have a maximum width of about 55 to 95 mm, 65 to 85 mm or about 75 mm. In some applications, the center section may have a maximum width of less than 110, less than 100, less than 95, less than 90, less than 85, less than 80, or less than 75 mm.
[171] In various applications, the first end section, second end section, and/or center section may have a variable width at different points along the longitudinal direction or may have a consistent width at different points along the length. longitudinal direction. In some applications, the first end section and second end section may have variable width at different points along the longitudinal direction and the center section may have a consistent width at different points along the longitudinal direction as illustrated in Figure 37. In some applications, the first end section and the second end section may have a width ranging from 145 mm maximum to 75 mm minimum. In these applications, the center section can have a consistent width of about 75 mm.
[172] In some applications, the absorbent core defines a first reference width 320 measured in 1/8 the length of the absorbent core 289, a second reference width 321 measured in/the length of the absorbent core 289, and a third width of reference 322 measured 7/8 of the length of absorbent core 289. In some applications, first reference width 320 may be equal to third reference width 322 and second reference width 321 may be less than first and third reference widths. reference 320 and 322. In some applications, the second reference width 321 may be less than 40%, 50%, 60%, 70%, or 80% of the first reference width 320 and/or the third reference width 322. In some applications, the second reference width 321 may be about 50% of the first reference width 320 and the third reference width 322.
[173] The absorbent core also defines an area of the absorbent core. In various applications, the area of the absorbent core can be any suitable value. For example, in an application adapted for use by a child weighing 60 to 120 pounds, the absorbent core area can be about 42,000 mm2. In an application adapted for use by a child weighing 38 to 65 pounds, the absorbent core area can be about 36,300 mm2.
[174] In many applications, the absorbent core can define any suitable shape. For example, the absorbent core may be symmetrical about the transverse centerline as illustrated in Figure 37 or it may be asymmetrical about the transverse centerline as illustrated in Figure 38. In various applications, the absorbent cores may have a rectangle shape, dog bone shape, hourglass shape, T-shaped or similar.
[175] In many applications, the perimeter seal can be of any suitable width and can be formed by any suitable method. Again referring to Figures 35-36, the width of the perimeter seal 241 is representatively illustrated. In some applications, the perimeter seal width may be at least 5, at least 10, at least 15, or at least 20 mm. The perimeter seal may include adhesive bonding, thermal bonding, ultrasonic bonding, pressure bonding and the like and combinations thereof. In some applications, the first sheet may be joined to the second sheet at the perimeter seal by adhesive bonding and the width of the perimeter seal may be at least 20 mm. In other applications, the first sheet may be joined to the second sheet at the perimeter seal by ultrasonic bonding and the width of the perimeter seal may be at least 10 mm.
[176] In some applications, the absorbent insert is substantially devoid of fluid impervious materials. In some applications, the absorbent insert does not include a fluid impermeable barrier layer. In comparison, many absorbent articles include a fluid impermeable backsheet or baffle that is provided to prevent liquid from contacting the wearer's clothing or a delay layer that is provided to retard or deflect fluid. In the present invention, the absorbent insert is positioned within the fluid impermeable pouch and therefore does not require a fluid impermeable layer as part of the absorbent insert. Additionally, this design is believed to be beneficial in some applications over conventional inserts because fluid can be absorbed by the absorbent insert along the entire strip, including the body-facing surface, garment-facing surface, and sides . Furthermore, the omission of a fluid impermeable layer eliminates the risk of fluid being trapped between the fluid impermeable pouch and the absorbent insert which can cause leakage during use or leakage upon removal of the absorbent insert from the pouch.
[177] In some applications, the absorbent insert may further include one or more input layers. For example, the absorbent insert 230 of Figures 35 and 36 is illustrated with a first input material 242 positioned between the first sheet 232 and the absorbent core 236. In some applications, the absorbent insert may additionally or alternatively include a second input material. . For example, the absorbent insert 244 of Figures 38 and 39 is illustrated with a first input material 242 and a second input material 246.
[178] Referring now to the Figures In Figures 38 and 39, a second example absorbent insert 244 is representatively illustrated. Figure 38 is a top view of absorbent insert 244 with portions cut away to better illustrate the underlying structure. Figure 39 is an expanded sectional view of the absorbent insert of Figure 38 taken along line D-D. The absorbent insert 244 includes a first sheet 232 and a second sheet 234 in frontal relationship with the first sheet 232. The absorbent insert 244 also includes an absorbent core 248 positioned between the first sheet 232 and the second sheet 234. The absorbent core 248 defines a core perimeter 238 and the first sheet and second sheet extend beyond the core perimeter 238 and are joined to form a perimeter seal 240.
[179] The first input material 242 is positioned between the absorbent core 248 and the first sheet 232 and the second input material 246 is positioned between the absorbent core 248 and the second sheet 234.
[180] In many applications, the first input material and/or the second input material can be any suitable length, width, or shape. For example, referring again to Figure In Figure 35, the first input material 242 defines an input material width 324 and a input material length 325. In various applications, the input material width may be from 50 to 70mm or about 62mm. In these applications, the width of the input material can be at least 70%, 80% or 90% of the second reference width 317 of the absorbent core. In some applications, the width of the input material may be about 84% of the second reference width 317 of the absorbent core.
[181] In some applications, the length of the lead-in material may be about 325 to 375 mm, 340 to 360 mm, or about 355 mm. In these applications, the length of the input material can be at least 70%, 80% or 90% of the length of the absorbent core. In some applications, the length of the input material can be about 88% of the length of the absorbent core.
[182] In many applications, the input materials can be rectangular as illustrated in Figure 35 or it can be any other suitable shape. For example, in various applications, input materials can be shaped similarly to the absorbent insert and/or the absorbent core.
[183] In various applications, any of the absorbent inserts of the present invention can include absorbent cores containing absorbent material and one or more overlay sheets. For example, in some applications, absorbent cores may include a single overlay sheet folded around the longitudinal side edges of the absorbent material and overlapping itself to form a fully coated absorbent core. In other applications, the absorbent core may include two overlay sheets. In these applications, one of the overlay sheets may be positioned primarily on a first front surface of the absorbent material. The other overlay sheet may be positioned primarily on the second front surface of the absorbent material. In these applications, the coating sheet on the second front surface may extend to the longitudinal side edges of the absorbent material, it may produce a coating around the longitudinal side edges of the absorbent material, or it may extend to the first front surface of the absorbent material. pad. Similarly, the cover sheet on the first front surface may extend to the longitudinal side edges of the absorbent material, it may produce a coating around the longitudinal side edges of the absorbent material, or it may extend to the second front surface of the absorbent material. pad. The coating sheets can overlap or can overlap each other.
[184] Again with reference to Figure In Figure 36, the absorbent core 236 is representatively illustrated with a first liner sheet 252 positioned on a first front surface 256 of the absorbent material 253. The first liner sheet 252 extends between the edges The absorbent core 236 also includes a second cover sheet 254 positioned on a second front surface 258 of the absorbent material 253. The second cover sheet 254 extends between the longitudinal side edges 260 of the absorbent material 253.
[185] Again with reference to Figure In Figure 39, the absorbent core 248 is representatively illustrated with an overlay sheet 262 positioned on a first front surface 256 of the absorbent material 253. The overlay sheet 262 extends around the side edges 260 of the absorbent material 253 and is also positioned on a second front surface 258 of the absorbent material 253. The cover sheet 262 may at least partially overlap itself at the overlap 264.
[186] In many applications, the first sheet and the second sheet can be made of the same material or they can be of different materials. In some applications, the first sheet and the second sheet may have the same basis weight, or they may be of different weights. The first sheet and/or the second sheet may be fluid permeable and may be made of substantially hydrophobic fibrous material. For example, the first sheet and/or the second sheet can be a strand of yarn joined after extrusion composed of synthetic polymer filaments. In some applications, the first sheet and/or the second sheet may be a blown cast web or a combed bonded web composed of synthetic polymer filaments. Suitable synthetic polymers include, for example, polyethylene, polypropylene, polyester and the like and combinations thereof. In some applications, both the first sheet and the second sheet are polypropylene nonwoven webs joined after extrusion having an individual basis weight of about 15 gsm. In some applications, the first sheet and/or the second sheet can be treated with surfactants to adjust the degree of hydrophobicity and wettability. In some applications, the first sheet and/or the second sheet may be embossed, punched, cut, or otherwise machined.
[187] The absorbent core typically includes an absorbent material composed of air-laid cellulosic fibers, commonly referred to as "fluff" cellulose. Other natural fibers, such as cotton, can also be used to form the absorbent core. The absorbent core can have a density ranging from about 0.18-0.30 grams/cc. This range of density allows the absorbent core to be flexible enough to conform readily to the wearer's body while still retaining sufficient rigidity for insertion into the pouch. In some applications, the absorbent core can have a density of about 0.24 grams/cc. The absorbent core may alternatively or additionally include a co-formed material composed of a mixture of cellulosic fibers and synthetic polymer fibers. For example, the co-formed material can be composed of an air-deposited mixture of cellulosic fibers and fused and blown polyolefin fibers such as polyethylene and/or polypropylene fibers. Furthermore, the absorbent core can have a dry thickness of about 3 to 5 mm, or about 4 mm, as measured under a containment pressure of 0.068 psi (0.47 kPa).
[188] The absorbent core may also include an effective amount of a high-absorbent inorganic or organic material (eg, superabsorbent) to improve the absorbency of the absorbent body. For example, the absorbent core may contain 5 to 95% by weight of the high absorbent material and preferably includes about 30 to 70, 40 to 60, or about 50% by weight of the high absorbent material to provide more performance. efficient. In some applications, the absorbent core can include equal amounts of "fluff" and superabsorbent cellulose. For example, in some applications, the absorbent core can include at least 14, at least 15, at least 16, at least 17, at least 18, or at least 19 grams of superabsorbent. In some applications, the absorbent core can include at least 14, at least 15, at least 16, at least 17, at least 18, or at least 19 grams of "fluff" cellulose. In some applications, the absorbent core can include about 19 grams of superabsorbent and about 19 grams of "fluff" cellulose. In other applications, the absorbent core can include about 17 grams of superabsorbent and about 17 grams of "fluff" cellulose.
[189] Suitable high absorbency inorganic materials include, for example, absorbent clays and silica gels. High absorbency organic materials can include natural materials such as agar, pectin, guar gum and peat moss, as well as synthetic materials such as synthetic hydrogel polymers. Such hydrogel polymers include, for example, carboxymethylcellulose, alkali metal salts of polyacrylic acids, polyacrylamides, polyvinyl ethers, hydroxypropyl cellulose, polyvinyl morpholinone, vinyl sulfonic acid polymers and copolymers, polyacrylates, polyacrylamides, polyvinyl pyridine and the like. Other suitable polymers include hydrolyzed acrylonitrile starch, hydrolyzed acrylic acid starch, and isobutylene maleic anhydride copolymers and mixtures thereof. Hydrogel polymers are preferably lightly cross-linked to impart the desired levels of water insolubility to the material.
[190] In some applications, the backing sheet may be a woven or non-woven material and may be composed of any suitable material. For example, the overlay sheet can be composed of polypropylene, cellulosic fabric and the like and combinations thereof. In some applications, the overlay sheet may be a non-woven material made of polypropylene bonded together after extrusion and may have a basis weight of about 10 gsm.
[191] The input layer or layers help to decelerate and spread swells or jets of fluid that can be quickly introduced into the absorbent insert. Desirably, the entry layer can quickly accept and temporarily hold fluid before releasing fluid into the absorbent core of the absorbent insert. In some applications, the entry layer may be an air-bonded combed weft composed of 39% hollow polypropylene fibers (6 denier) and 60% bicomponent (6 denier) fibers (bicomponent sheath: polypropylene core). In many applications, the inlet layer can have any suitable basis weight. For example, the input layer can have a basis weight of at least 30, at least 50, at least 75, at least 100, or at least 125 grams per square meter (gsm). In some applications, the input layer may have a basis weight of approximately 128 gsm. Other examples of suitable input layers are described in U.S. Patent No. 5,486,166; No. 5,490,846; and No. 5,820,973. The entire disclosures of these patents are hereby incorporated by reference to the extent that they are consistent (i.e., not in conflict) with this document.
[192] In some applications, the absorbent insert may have a first input layer and a second input layer. In some applications, the first input layer may be the same material as the second input layer, or it may be a different material. In some applications, the first input layer may have the same basis weight as the second input layer, or it may be a different basis weight.
[193] In some applications, the absorbent inserts of the present invention can be characterized, at least in part, by specific absorbent properties. For example, in some applications, the absorbent inserts can have a total absorbent capacity of at least 600 grams, at least 650 grams, at least 700 grams, or at least 750 grams of 0.9% saline solution. In some applications, the absorbent inserts can have an absorbent capacity of about 740 grams or about 827 grams. The total absorbent capacity of the absorbent inserts can be determined using the Retention Capacity Test Method. This test method measures the amount of fluid held by an absorbent insert under external pressure. An initial weight of the absorbent insert is measured and then the absorbent insert is submerged in a 0.9% saline solution for 20 minutes. After the saturation time, 0.5 psi of pressure is applied to the entire absorbent insert for 5 minutes and excess saline is drained off. After the pressing time, the weight of the saturated absorbent insert is measured. Total absorbent capacity is calculated as the saturated weight minus the initial weight.
[194] In some applications, absorbent inserts may have a first inlet rate measured across a first main surface and may have a second inlet rate measured through a second main surface that is located opposite the first main surface. In some applications, the first main surface may be adapted for positioning towards the wearer's body and the second main surface may be adapted for positioning towards the fluid impermeable pouch (i.e., towards the wearer's garment). In some applications, the first entry rate and/or the second entry rate may be determined by the cradle entry test method. This test measures the time required for an absorbent insert to absorb a specific volume of 0.9% saline solution (urine emission). The absorbent insert is positioned within a test cradle with the first main surface (body facing surface) up and the second main surface (garment facing surface) down towards the crib to determine the first input rate . The absorbent insert is positioned within a test cradle with the second main surface (garment-facing surface) up and the first main surface (body-facing surface) down towards the cradle to determine the second input rate . The urine emission site is located in relation to the transverse centerline of the pants. For products designed for users weighing 38 to 65 pounds, the urine emission location is 150 mm in front of the transverse centerline for boys and is 90 mm in front of the transverse centerline for girls and the urine emission volume is 120 ml for both. For products designed for users weighing 60 to 120 pounds, the location of the urine output is 170 mm in front of the transverse centerline for boys and 80 mm in front of the transverse centerline for girls and the volume of urine emission is 220 ml for both. The saline solution flow rate is 15 ml/second and the saline solution has a temperature of 98.6 degrees F. The respective absorbent inserts receive a first-time urine emission at the aforementioned locations, volumes and flow rates. The time required for the absorbent insert to completely absorb the first urine output is recorded. After 15 minutes, the respective absorbent inserts receive a urine emission a second time at the aforementioned locations, volumes and flows. The time required for the absorbent insert to completely absorb the second urine output is recorded.
[195] In some applications, the first entry rate may be less than 30 seconds for the first urine output and less than 100 seconds for the second urine output. In some applications, the second entry rate may be less than 30 seconds for the first urine output and less than 100 seconds for the second urine output. In some applications, the ratio of the first entry rate to the second entry rate for the first urine output may be at least 1:3, at least 1:2, at least 1:1.5, or about 1: 1.
[196] In some applications, absorbent inserts can be characterized by total absorbent capacity as a proportion of the width of the genital region. In some applications, products designed for users weighing 60 to 120 pounds may have an absorbent capacity of around 827 grams and a width in the genital region of around 74 mm. In other applications, products designed for users weighing 38 to 65 pounds may have an absorbent capacity of about 740 grams and a genital area width of about 74 mm. Therefore, in some applications, the ratio of the total absorbent capacity to the width in the genital area may be at least 9g/mm, at least 10g/mm, or at least 11g/mm.
[197] The absorbent inserts of the present invention may be provided in any suitable form. For example, absorbent inserts can be folded, stacked, wrapped, compressed, or the like and combinations thereof. In some applications, the absorbent inserts can be packaged individually in a package. In some applications, the absorbent inserts can be folded one or more times before being placed in a package. In some applications, the absorbent inserts can be folded twice before being placed in the package.
[198] In some applications, the absorbent inserts of the present invention include a first sheet, a second sheet, an entry layer, and an absorbent core. In these applications, the absorbent core can be positioned between the first sheet and the second sheet. Furthermore, the entry layer can be positioned between the first sheet and the absorbent core. In this configuration, the first sheet is designated as the body side and the second sheet is designated as the garment side of the absorbent insert.
[199] In various applications, the absorbent insert can be folded a first time so that a first body side portion is in front relationship with a second body side portion. In these applications, the absorbent insert can be folded a second time so that a third body side portion is in frontal relationship with a first garment side portion. In other applications, the absorbent insert may be folded a first time so that a first garment side portion is in frontal relationship with a second garment side portion. In these applications, the absorbent insert can be folded a second time so that a third garment side portion is in frontal relationship with a first body side portion.
[200] In some applications, the first ply can be positioned so that the absorbent insert is effectively folded into equal halves. In some applications, the first ply and second ply can be positioned so that the absorbent insert is effectively folded into approximately equal thirds.
[201] In many applications, folded absorbent inserts can be individually wrapped in any suitable packaging material. Conventionally, the package is composed of one or more layers of a thin sheet or film of thermoplastic material, such as polyethylene, which is folded around the absorbent article and then sealed by using heat and/or pressure, ultrasound or a adhesive to form a package or bag. In various applications, packaging can include films made from poly(vinyl alcohol), polyvinyl acetate, ethylene vinyl alcohol, polyurethane, ethylene methyl acrylate, and ethylene methyl acrylic acid to make them breathable. In some applications, the packaging material may also be a laminate of different materials, such as a film/non-woven laminate. The pack may have a sealed side or edge that is designed to be opened by breaking or tearing the material on or adjacent to the seal in order to later remove the absorbent insert. With some package designs, a flap is provided that folds over the bag opening and can be attached to the front of the bag with adhesive applied between the bag and the flap, or with a piece of tape. The sides of the flap can be sealed with the sides of the pouch and can be separated before removing the absorbent article.
[202] The containment pants and absorbent inserts of the present invention are adapted to work together as a containment system. In various applications, the containment system includes one or more containment pants such as those described herein and one or more absorbent inserts such as those described herein. Suitable containment systems are also described in United States patent application xx/xxx, xxx entitled "Containment System", filed July 12, 2012, and containing procedural registration number 64816460US03, the entirety of which is incorporated herein by reference.
[203] In use and prior to placement, the absorbent inserts are positioned within the pouch that is suspended within the containment pants. After the absorbent insert is positioned, the containment system is pulled into place like a conventional underwear. The containment pants are adapted to hold the absorbent insert in position to accept one or more user urine emissions. The absorbent insert is adapted to quickly allow the entry and absorption of urine. The bag is impervious to fluid and is adapted to hold any urine that cannot be immediately absorbed by the absorbent insert. In some applications, the absorbent insert is permeable to fluid on the garment facing surface and/or on the side edges as well as the side surface of the body. Therefore, any urine retained by the fluid impermeable bag can be drawn into the absorbent insert through the body facing surface and/or the side edges. The used absorbent insert can be removed from the fluid impermeable pouch and the containment pant can be washed prior to reuse with a new absorbent insert.
[204] In a variety of applications, the absorbent inserts of the present invention may be secured to the containment trouser pockets by any suitable means. For example, the absorbent inserts can be attached to the pouches by means of button fasteners, a snap button, Velcro, pressure sensitive adhesive, and the like and combinations thereof. In some applications, the absorbent inserts may be additionally or alternatively held in place by the structure of the fluid impermeable pouch containment flaps. For example, the containment tabs can include end pockets that help secure a portion of the absorbent insert within the pockets. In some applications, the containment tabs may include a tab elastic that provides pulling forces that help secure the absorbent insert within the pouch. In some applications, the absorbent inserts are held in place only by the structure of the containment flaps and/or end pockets. In some applications, the absorbent inserts are held in place only by the structure of the containment tabs and the containment tab elastic and are devoid of fasteners. In some applications, the absorbent inserts are devoid of containment tabs. In these applications, fluid containment is provided by the bag's containment flaps.
[205] In various applications, the containment system may include a containment pants, containing a pouch with a base surface area of the pouch, a length, width, and/or shape adapted to accommodate a specific absorbent insert containing an insert. complementary absorbent and/or an area, length, width and/or shape of an absorbent core. This complementary area, length, width and/or shape is believed to improve placement of the absorbent insert in the body, to help contain the absorbent insert within the pouch and provide a smooth fit and discreet appearance.
[206] In some applications, a containment pants may have a bag with a bag base surface containing a length of the bag base surface. Similarly, the absorbent insert may have an absorbent insert length and/or an absorbent core length that is less than or equal to the length of the base surface of the pouch. In some applications, the length of the absorbent insert and/or a length of the absorbent core can be at least 70%, at least 80%, at least 90%, or at least 95% of the length of the base surface of the pouch. In one application, the length of the absorbent core can be 91% of the length of the base surface of the pouch. In these applications, the length of the absorbent insert and/or a length of the absorbent core can be 100% or less of the length of the base surface of the pouch. Containing an absorbent insert length and/or an absorbent core length for a pouch base surface length in these bands is believed to keep the absorbent insert secure within the pouch without excessive deformation or movement which can negatively affect performance and/ or comfort. An absorbent insert shorter than this range is more likely to cause movement or breakage of the bag seal which is likely to result in leakage. An absorbent insert longer than this range is likely to result in kinking and accumulation within the bag and can result in a poor user experience due to discomfort and/or loss of discretion.
[207] In some applications, a containment pants may have a bag with a bag base surface containing a maximum bag base surface width and a minimum bag base surface width where the maximum width is the minimum width are different. Similarly, the absorbent insert may have a maximum width of the absorbent insert and/or the absorbent core and a minimum width of the absorbent insert and/or the absorbent core where the maximum width and the minimum width are different. In some applications, the maximum width of the absorbent insert and/or absorbent core is at least 80%, at least 90% or at least 95% of the maximum width of the base surface of the pouch. In one application, the maximum width of the absorbent core is at least 85% of the maximum width of the base surface of the pouch. In these applications, the maximum width of the absorbent insert and/or the absorbent core can be 100% or less of the maximum width of the base surface of the pouch. In some applications, the minimum absorbent insert width and/or the minimum absorbent core width is at least 80%, at least 90%, or at least 95% of the minimum width of the base surface of the pouch. In one application, the minimum width of the absorbent core can be 91% of the minimum width of the base surface of the pouch. In these applications, the minimum width of the absorbent insert and/or the absorbent core can be 100% or less of the minimum width of the base surface of the pouch.
[208] In some applications, a containment pants may have a pouch with a pouch base surface having a maximum pouch base surface width at a front and/or a rear portion and a minimum pouch base surface width. bag in a central portion where the maximum width and minimum width are different. Similarly, the absorbent insert and/or absorbent core may have an absorbent insert and/or maximum absorbent core width in a front portion and/or a rear portion and a minimum absorbent insert and/or absorbent core width in a central portion. where the maximum width and minimum width are different. In some applications, the minimum width of the base surface of the pouch may be less than 80%, less than 70%, less than 60%, or about 62% of the maximum width of the base surface of the pouch. Similarly, the minimum width of the absorbent insert and/or the absorbent core can be less than 80%, less than 70%, less than 60%, or about 62% of the maximum width of the absorbent insert and/or the absorbent core .

Similarly, the absorbent insert may have an absorbent insert area and/or an absorbent core area that is less than or equal to the base surface area of the pouch. In some applications, the absorbent insert area and/or the absorbent core area can be at least 80%, at least 90%, or at least 95% of the base surface area of the pouch. In some applications, the area of the absorbent core is 76% of the base surface area of the pouch. In these applications, the absorbent insert area and/or absorbent core area can be 100% or less of the base surface area of the pouch. For example, in one application, the area of the absorbent core can be about 42,218 mm2 which represents 76% of the pocket surface area of about 55,270 mm2. In another application, the area of the absorbent core can be about 36,296 mm2 which represents 76% of the base surface area of the pouch of about 47,778 mm2.
[211] In some applications, a containment pants may have a pouch with a base surface of the pouch containing a shape of the base surface of the pouch and the absorbent insert and/or absorbent core may have a shape of the absorbent insert and/or a shape of the absorbent core that is substantially the same as the shape of the base surface of the pouch. In one application, the base surface of the pouch may have a curved perimeter in the form of a bow tie and the absorbent insert and/or absorbent core may have a curved perimeter in the form of a bow tie of similar length and/or width. For example, the base surface of the pouch can be a bow-tie shape as illustrated in Figure 28 and the absorbent core can be a bow-tie shape as shown in Figure 37. In another application, the base surface of the bag may have a torch-shaped curvilinear perimeter and the absorbent insert and/or the absorbent core may have a torch-shaped curvilinear perimeter of similar length and/or width.

[212] In some applications, the containment system of the present invention provides a first containment pants, a second containment pants, and an absorbent insert. In these applications, the first containment pants have a first configuration and the second containment pants have a second configuration different from the first configuration. For example, in some applications, the first containment pants may have a structure designed for men's use as illustrated in Figure 1 while the second containment pants may have a structure designed for women's use as illustrated in Figure 6. The differences between the the first containment pants and the second containment pants may include the frame shape, the frame design, the strip construction, the bag construction, the bag location and the like and combinations thereof. For example, in the first containment pants, the bag can be located farther forward from the containment pants for better alignment with the male anatomy. In contrast, in the second containment pants, the bag may be more centrally located for better alignment with the female anatomy.
[213] In one application, the present invention provides a method for providing a containment system that includes providing a first permanently closed containment pants such as those disclosed herein and a second permanently closed containment pants such as those disclosed herein. The first containment pants include a first fluid impermeable pouch defining a first pouch construction and a first pouch base surface. The first base surface of the pouch containing a first end section, a second end section and a center section extending between the first end section and the second end section. The first end section of the first containment pants defines a maximum width of at least 135 mm, at least 145 mm, at least 155 mm, or at least 165 mm, the center section of the first containment pants defines a minimum width of minus 110 mm, less than 100 mm, or less than 95 mm, and the second end section of the first containment pants defines a maximum width of at least 135 mm, at least 145 mm, at least 155 mm, or at least 165 mm. Similarly, the second containment pants include a second fluid-impermeable pouch that defines a second pouch construction and a second pouch base surface. At the second base surface of the pouch containing a first end section, a second end section and a center section extending between the first end section and the second end section. The first end section of the second containment pants defines a maximum width of at least 135 mm, at least 145 mm, at least 155 mm, or at least 165 mm, the center section of the second containment pants defines a minimum width of minus 110 mm, less than 100 mm, or less than 95 mm, and the second end section of the second containment pants defines a maximum width of at least 135 mm, at least 145 mm, at least 155 mm, or at least 165 mm . In some applications, the first base surface of the pouch defines a first base surface length and the second base surface of the pouch defines a second base surface length that is 95% to 105% of the first base surface length. Thus, the first base surface of the pouch is of equal or similar dimensions at the same or similar positions as occurs in the second base surface of the pouch. However, while the first bag construction can be any suitable construction, including those disclosed in this document, and the second bag construction can be any suitable construction, including those disclosed in this document, the first bag construction may be different from the second bag construction. handbag. For example, in some applications the first pouch construction may be as illustrated in Figures 28-31 and the second pouch construction may be as illustrated in Figures 17-22.
[214] In some applications, the first permanently closed containment pants include a first containment strap containing a first transition that is joined between the first fluid impermeable pouch and the front waist region. The first transition defines a length in the longitudinal direction. The first permanently closed containment pants include a second transition joined between the first fluid impermeable pouch and the back waist region. The second transition defines a length in the longitudinal direction. In these applications, the second permanently closed containment pants include a second containment strip containing a first transition that is joined between the second fluid impermeable pouch and the front waist region. The first transition defines a length in the longitudinal direction. The second permanently closed containment pants include a second transition that is joined between the second fluid impermeable pouch and the back waist region. In some applications, the length of the first transition of the first strip is greater than the length of the first transition of the second strip. In some applications, the length of the second transition of the first strip is less than the length of the second transition of the second strip.
[215] However, despite the differences between the containment pants between the first containment pants and the second containment pants, both can be constructed with pouches containing pouch base surfaces of similar length, width, and/or shape. Therefore, a single absorbent insert can be provided for use with both the first containment pants and the second containment pants. For example, in some applications, the present invention provides a method for providing a containment system. The method includes providing a first permanently closed containment pants like those described herein and providing a second permanently closed containment pants like those described herein. The method also includes providing a discrete absorbent insert that is sized and shaped to work in conjunction with both the first containment pants and the second containment pants. In some applications, the first containment pants may include a first pocket and the second containment pants may include a second pocket having a similar size and shape as the first pocket. However, despite the similarities, the first containment pants and the second containment pants may have different frame constructions, bag construction, strap construction, bag positioning, or other differences or combinations thereof.
[216] In some applications, the containment system of the present invention includes one or more absorbent inserts having a designated body side and a designated garment side. In other words, in some applications, absorbent inserts are designed to be oriented with a specific side facing the user to maximize the performance of the absorbent insert. For example, in some applications, the absorbent insert may have a single entry layer located on one side of the absorbent core. In these applications, it is desirable for the user to orient the absorbent insert within the pouch so that the entry layer faces the user. In the present orientation, the absorbent insert is positioned to rapidly receive fluid through the entry layer and retain the liquid in the absorbent core.
[217] To help users correctly orient the absorbent insert in the pouch, several references may be provided. In some applications, the absorbent insert may include a color in one or more of the components. In some applications, the absorbent insert may include an entry layer that has a color that is distinguishable from the other components of the absorbent insert. For example, in some applications, the input layer might have a blue color and the surrounding components might have a white color. In these applications, the user can be instructed to identify the blue input layer and position it facing the body. In this way, the user has a simple visual reference to quickly, repeatedly and properly orient the absorbent insert within the pouch.
[218] In some applications, absorbent inserts may be supplied folded into individual packages. In these applications, the absorbent inserts can be bent to define a bending direction. Absorbent inserts can be folded twice, thrice or similar times. In these applications, the absorbent inserts can be bent so that the resulting curvature is directed to the side of the absorbent insert that is desirably oriented towards the user. For example, the absorbent insert can have a single entry layer located on one side of the absorbent core. The absorbent insert can be folded so that the absorbent insert is concave towards the side with the input layer. In use, this concave formation fits naturally into the concave formation of the pouches within the containment pants. As such, the user is given referrals to position the absorbent insert within the pouch with the entry layer oriented towards the user's body.
[219] Although the invention has been described in detail with regard to its specific configurations, those skilled in the art will understand that, after having obtained an understanding of the above, they will immediately be able to devise changes, variations and equivalents of said configurations. Therefore, the scope of the present invention should be evaluated in accordance with the appended claims and their equivalents. In addition, all combinations and/or sub-combinations of the disclosed configurations, ranges, examples and alternatives are also included.
