HISTORY OF THE INVENTION
[001] Absorbent articles such as sanitary napkins, daily intimate pads and incontinence diapers are designed to absorb and retain fluids excreted by the human body. It is desirable that said absorbent articles conform to the wearer's body during use. An absorbent article with a body conformable structure can increase the effectiveness of the absorbent article by reducing the possibility of fluids, such as menses or urine, from leaking beyond the perimeter of the absorbent article. In addition, an absorbent article with a body-adaptive structure may also be more comfortable to wear compared to similar absorbent articles that do not have a body-adaptive structure.
[002] Keeping an absorbent article, such as an incontinence diaper, in the proper position relative to the wearer's body is difficult due to external forces exerted on the absorbent article under dynamic conditions. These external forces can be the result of the fixation of the absorbent product to the wearer's clothing or can be the result of bodily movement, in particular, movement of the thighs. During use, these forces can cause the absorbent article to pull away from the body or move out of the desired position.
[003] There has been an attempt by the above absorbent articles to introduce body-adaptive elements close to the body side of the absorbent article. While these attempts have met with some success, there remains a need for an elevated body adaptable structure that aligns with the female anatomy to rapidly capture fluids, maintain a dry surface, effectively distribute fluids throughout the product, and adapt. to the contours of the body during its use. SUMMARY OF THE INVENTION
[004] In one aspect, the present invention provides an absorbent article having a body side liner, a rear lamina and an absorbent body positioned between the body side liner and the rear lamina, wherein the absorbent body defines a length of the absorbent body. The absorbent article also includes a body-adaptive structure positioned in a relationship directly facing the body-side liner. The body-adaptive structure defines a body-adaptive structure length that is at least 50% of the length of the absorbent body. The body-adaptive structure is aligned with a longitudinal centerline of the absorbent article. The body-adaptive structure defines a front portion having a median anterior portion width, a posterior portion having a median posterior portion width, and a central portion positioned between the anterior portion and the posterior portion and having a median central portion width. The median width of the anterior portion is greater than the median width of the central portion and the median width of the central portion is greater than the median width of the posterior portion. The anterior portion includes a shaft, the central portion includes a channel, and the posterior portion includes a narrowing. The well transitions into the channel through a first convex transition and a concave transition. The channel transitions into the nip via a second convex transition.
[005] In some configurations of this aspect, the body-adaptive structure defines a longitudinal centerline and a lateral centerline, wherein the body-adaptive structure is symmetrical with respect to the longitudinal centerline and asymmetrical with respect to the lateral centerline.
[006] In some configurations of this aspect, the lateral centerline divides the body-adaptive structure into an anterior portion having an anterior portion area and a posterior portion having an posterior portion area, where the anterior portion area is greater than the area of the posterior portion.
[007] In some configurations of this aspect, the body-adaptive structure is positioned between the body-side liner and the absorbent body, wherein also the body-side liner is joined to the absorbent body at one or more shaping joints located at the around a perimeter of the structure adaptable to the body. In some configurations, the body-side liner is joined to the absorbent body in a plurality of shaping joints near the perimeter of the body-adaptive structure at the rear portion.
[008] In some configurations of this aspect, the absorbent article further includes a complementary body-adaptive structure positioned between the body-side liner and the body-adaptive structure. The structure adaptable to the complementary body defines a shape and defines an area. The body-adaptive structure defines a shape and defines an area. The shape of the frame adaptable to the complementary body is substantially similar to the shape of the frame adaptable to the body. In some configurations, the area of the adaptive frame to the complementary body is smaller than the area of the adaptable frame to the body.
[009] In some configurations of this aspect, the body-adaptive structure is a distinct element positioned between the body-side liner and the absorbent body, and is devoid of cellulose fibers or superabsorbent material. In some configurations, the body-adaptive structure is made of a carding and press-setting batt of polypropylene fibers having a basis weight of at least 100 gsm.
[010] In another aspect, the present invention provides an absorbent article having a body side liner, a backsheet and an absorbent body positioned between the body side liner and the backsheet, wherein the absorbent body defines a length of the absorbent body. The absorbent article further includes a body-adaptive structure positioned in a directly facing relationship to the body-side liner. The body-adaptive structure is a non-woven fabric that is substantially devoid of cellulose fibers and superabsorbent material. The body-adaptive structure defines a body-adaptive structure length that is at least 50% of the length of the absorbent body. The body-adaptive structure is aligned with a longitudinal centerline of the absorbent article. The body-adaptive structure defines a front portion having a median anterior portion width, a posterior portion having a median posterior portion width, and a central portion positioned between the anterior portion and the posterior portion and having a median central portion width. The median width of the anterior portion is greater than the median width of the central portion and the median width of the central portion is greater than the median width of the posterior portion. The anterior portion includes a shaft, the central portion includes a channel, and the posterior portion includes a narrowing. The well transitions into the channel via a first convex transition and a concave transition, where the channel also transitions into the narrowing via a second convex transition.
[011] In some configurations of this aspect, the body-adaptive structure is a non-woven fabric of batt by carding and pressure setting made from polypropylene fibers. In some configurations, the body-adaptive frame has a basis weight of at least 200 gsm.
[012] In some configurations, the absorbent article defines a thickness and the body-adaptive structure defines a thickness that is at least 25% of the thickness of the absorbent article.
[013] In some configurations, the absorbent body includes a body-side absorbent layer and a retaining layer positioned between the body-side absorbent layer and the backsheet. The body-side absorbent layer is made of material made by pneumatic compaction and the retaining layer comprises 70 to 90% superabsorbent material.
[014] In some configurations, the body-adaptive structure defines a longitudinal centerline and a lateral centerline, where the body-adaptive structure is symmetrical about the longitudinal centerline and asymmetrical about the lateral centerline. The lateral centerline divides the body-adaptive structure into an anterior portion having an anterior portion area and a posterior portion having a posterior portion area, where the anterior portion area is greater than the posterior portion area.
[015] In some configurations of this aspect, the absorbent article further includes a complementary body-adaptive structure positioned between the body-side liner and the body-adaptive structure. The structure adaptable to the complementary body defines a shape and defines an area. The body-adaptive structure defines a shape and defines an area. The shape of the structure adaptable to the complementary body is substantially the same as the shape of the structure adaptable to the body and the area of the structure adaptable to the complementary body is smaller than the area of the structure adaptable to the body.
[016] In another aspect, the present invention provides a range of absorbent articles. The range includes a first absorbent article and a second absorbent article. The first absorbent article includes a first body side liner, the first back lamina, a first absorbent body positioned between the first body side liner and the first back lamina, wherein the first absorbent body defines a length of the first absorbent body. . The first absorbent article also includes a first body-adaptive structure positioned in direct relationship to the first body side facing. The first body-adaptive structure is aligned with a longitudinal centerline of the first absorbent article. The first body-adaptive structure has a length of the first body-adaptive structure that is at least 50% of the length of the first absorbent body. The body-adaptive first structure defines an area of the body-adaptive first structure, a shape of the body-adaptive first structure, a front portion having a median anterior portion width, a posterior portion having a median posterior portion width, and a central portion positioned between the anterior portion and the posterior portion also having a median width of the central portion. The median width of the anterior portion is greater than the median width of the central portion and the median width of the central portion is greater than the median width of the posterior portion.
[017] The second absorbent article includes a second body side liner, a second back sheet, a second absorbent body positioned between the second body side liner and the second back sheet, wherein the second absorbent body defines a length of the second absorbent body. The second absorbent article also includes a second body-adaptive structure positioned in direct relationship to the second body side skin that is aligned with a longitudinal centerline of the second absorbent article. The second body-adaptive structure has a length of the second body-adaptive structure that is at least 50% of the length of the second absorbent body. The second body-adaptive structure defines an area of the second body-adaptive structure, a shape of the second body-adaptive structure, a front portion having a median anterior portion width, a posterior portion having a median posterior portion width, and a central portion positioned between the anterior portion and the posterior portion, also having a median width of the central portion. The median width of the anterior portion is greater than the median width of the central portion and the median width of the central portion is greater than the median width of the posterior portion.
[018] In the range of articles, the length of the first absorbent body is at least 10% greater than the length of the second absorbent body and the shape of the first body-adaptive structure is substantially equal to the shape of the second body-adaptive structure.
[019] In some embodiments of this aspect, the first absorbent body includes a peripheral edge of the first absorbent body that defines a shape of the first absorbent body and the second absorbent body includes a peripheral edge of the second absorbent body that defines a shape of the second absorbent body which is different from the shape of the first absorbent body.
[020] In some embodiments of this aspect, the range further includes a third absorbent article. The third absorbent article includes a third body side facing, a third rear lamina, a third absorbent body positioned between the third body side facing and the third rear lamina. The third absorbent body includes an opening and defines a length of the third absorbent body. The opening defines an opening area, an opening shape, an anterior portion having a median anterior portion width, a posterior portion having a median posterior portion width, and a central portion positioned between the anterior portion and the posterior portion, also having a median width of the central portion. The median width of the anterior portion is greater than the median width of the central portion and the median width of the central portion is greater than the median width of the posterior portion. The opening includes a peripheral edge that defines a shape of the opening that is substantially the same as the shape of the first body-adaptive structure and the shape of the second body-adaptive structure.
[021] In some embodiments of this aspect, the third absorbent body defines a length of the third absorbent body and the opening defines an opening length that is at least 50% of the length of the third absorbent body. BRIEF DESCRIPTION OF THE DRAWINGS

[029] The disposable absorbent articles of the present invention include an adaptable body structure that aligns with the female anatomy that is believed to improve fit, comfort, dryness and performance against leaks. The body-adaptive structure has a geometry that aligns an anterior portion of the body-adaptive structure with the urethra, a central portion of the body-adaptive structure with the genital lips and pelvic floor, and a posterior portion of the body-adaptive structure with the cleft gluteal. The body-adaptive structure is adapted to temporarily accept and carry urine outputs and to minimize leakage. During use, the body-adaptive structure quickly becomes saturated and thus delivers urine over a wide area of the surface of the absorbent article. It is believed that the relatively narrow width of the body-adaptive structure minimizes the compressive forces generated by the movement of the upper thighs, which could reduce the void volume. The saturated body-adaptive structure is then desorbed into the absorbent body, which results in a relatively dry surface close to the body.
[030] Figs. 1-4 representatively illustrate a first configuration of a disposable absorbent article 10 of the present invention. Fig. 1 is a top perspective projection of the absorbent article 10. Fig. 2 is a top perspective projection of the absorbent article 10 of Fig. 1 in which portions have been cut away to illustrate the underlying structure. Fig. 3 is an enlarged projection of the absorbent article 10 of Fig. 1. Fig. 4 is a top plane projection of the absorbent article 10 of Fig. 1 where portions have been cut away to reveal the underlying structure. The absorbent article 10 includes a liquid-permeable upper lamina (also called a body-side liner) 20, a substantially liquid-impervious back lamina 22, and an absorbent body 24 positioned between the back lamina 22 and the upper lamina 20. The article absorbent 10 further includes a body-adaptive structure 32 in a facing relationship to the upper lamina 20. In some configurations, the upper lamina may be located between the body-adaptive structure and the rear lamina (not shown). In other configurations, body adaptable structure 32 may be located between upper lamina 20 and absorbent body 24, as illustrated. In some embodiments, the absorbent articles of the present invention may further include containment tabs, garment attachment adhesive, a peel-off strip, or combinations thereof. For example, the absorbent article 10 illustrated in Figs. 14 includes containment tabs 40 which, in turn, include containment elastics 42 and a containment tab carrier mat 44. Likewise, the absorbent article 10 of Figs. 1-4 is shown with an optional garment attachment adhesive 46 applied to the rear blade 22 and covered with a detachable strip 48.
[031] In various configurations, the absorbent body 24 can be formed by a single layer of material or can be formed by two or more layers of material. For example, the absorbent body 24 can be formed of two layers of material as illustrated in Fig. 3. Specifically, the absorbent body 24 can include a retaining layer 26 and a body-side absorbent layer 28. The retaining layer 26 can be positioned toward the back lamina 22 and the body side absorbent layer 28 can be overlaid on the retaining layer 26 and positioned toward the top lamina 20, as illustrated. In other embodiments, the relative orientation of the retaining layer and the body-side absorbent layer may be reversed (not shown). Regardless of whether it is a single layer or multiple layers, the absorbent body defines an absorbent body length, an absorbent body width, and an absorbent body perimeter. The perimeter of the absorbent body further defines an area of the absorbent body. In configurations where the absorbent body includes two or more layers, the length of the absorbent body, the width of the absorbent body, the perimeter of the absorbent body and the area of the absorbent body are defined by the widest range, in the plane defined by the longitudinal direction and the direction. side of any of the layers.
[032] Now, with respect to Fig. 5, a projection of the upper plane of the structure adaptable to the body 32 of Figs. 1-4 is representatively illustrated. The body-adaptive structure 32 defines a peripheral edge 33 and defines an area 34. In various configurations, the body-adaptive structure 32 may be symmetrical with respect to a longitudinal centerline 50. In some configurations, the body-adaptive structure 32 may be symmetrical about a lateral centerline 52. For example, as illustrated in Fig. 5, the body adaptable structure 32 is symmetrical about the longitudinal centerline 50 and asymmetrical about the lateral centerline 52.
[033] Lateral centerline 52 divides the body adaptable structure into an anterior half 64 and a posterior half 66. The anterior half 64 defines an area of the anterior half 65 and the posterior half 66 defines an area of the posterior half 67. As per used herein, the term "anterior" refers to that portion of the structure, layer or article that is adapted to be oriented towards the front of the user during normal use. Similarly, as used herein, the term "rear" refers to that portion of the structure, layer or article that is adapted to be oriented towards the rear of the wearer during normal use. In many configurations, the front half area 65 is larger than the back half area 67.
[034] The body adaptable structures 32 of the present invention also define an anterior portion 56, a posterior portion 60 and a central portion 58 positioned between the anterior portion 56 and the posterior portion 60. The anterior portion 56 is defined as the third anterior of the body-adaptive structure, the central portion 58 is defined as the middle third of the body-adaptive structure and the posterior portion 60 is defined as the posterior third of the body-adaptive structure, all measured in relation to the longitudinal centerline 50 .
[035] The absorbent articles of the present invention may include side edges of any suitable shape. For example, the side edges can be straight or can have arcuate shapes such as concave curves, convex curves or combinations between them. Again with reference to Figs. 1 and 4, the absorbent article 10 is illustrated with side edges 53 that are concave. The combination of the two side edges 53 in this configuration combine to create a curved shape. Similarly, the absorbent body of the present invention may include side edges of any suitable shape. For example, the side edges of the absorbent body can be straight or can have arcuate shapes such as concave curves, convex curves or combinations between them. Similarly, one or more of the layers of the absorbent body can include side edges that are straight, concave, convex, or overlapping therebetween. For example, now referring to Fig. 4, both the body side absorbent layer 28 and the retaining layer 26 are illustrated with side edges 54 that are concave. The concave side edges 54 define a minimum width 61.
[036] In some configurations, the minimum width of the body-side absorbent layer is, as a rule, aligned with the lateral centerline of the body-adaptive structure (not shown). In some configurations, the minimum width 61 of the body-side absorbent layer 28 is aligned between the lateral centerline of the body-adaptive structure 32 and the front portion 56 of the body-adaptive structure 32, as illustrated in Fig. 4.
[037] As illustrated, the front portion 56 of the frame adaptable to the body 32 includes a portion of the well 110, whose shape is, as a rule, rectangular and has a relatively large lateral dimension. During use, the well portion 110 is adapted to be positioned adjacent the user's urethra. It is believed that this positioning, together with this shaping of the well portion 110 minimizes the bending of the absorbent article in this region, thus preserving the void volume of the well portion 110 for receiving bodily fluids.
[038] Similarly, the central portion 58 of the body adaptable structure 32 includes a channel portion 112, whose shape is, as a rule, rectangular and has a longitudinal dimension that is greater than the lateral dimension. During use, the channel portion 112 is adapted to be positioned close to the genital lips. It is believed that this positioning, together with this shaping of the channel portion 112, allows compression of the absorbent article 10 by the wearer's legs while still allowing fluid to move freely between the front portion 56 and the rear portion 60.
[039] The rear portion 60 of the body adaptable frame 32 includes a taper portion 114 which, as a rule, has an acute triangle shape, the smallest of the three angles being located at the rear end of the shape. In various configurations, the nip portion 114 may terminate in a relatively sharp corner (not shown) or may terminate in a more rounded corner as illustrated in Fig. 5. During use, the nip portion 114 is adapted so as to be positioned close to the gluteal cleft. It is believed that this positioning, together with this shaping of the narrowing portion 114 promotes a longitudinal peak in the rear portion of the absorbent article that lines up with the gluteal cleft.
[040] The transition between the well portion and the channel portion is marked by a distinctive but smooth change in curvature. In some configurations, the longitudinal edges 119 of the well portions 110 include sections 121 which, as a rule, are parallel to the longitudinal centerline 50. Similarly, in some configurations, the longitudinal edges 119 of the channel portions 112 include sections 123 which, as a rule, are parallel to the longitudinal centerline 50. In these and other configurations, well portions 110 transition into channel portions 112 by both a first convex transition 117 and a concave transition 116 along both longitudinal edges 119. The first convex transition 117 can define any suitable angle 167. In some configurations, angle 167 can be between 110 to 160 degrees, 120 to 150 degrees, or approximately 135 degrees. Similarly, concave transition 116 can define any suitable angle 166. In some configurations, angle 166 can be between 30 to 60 degrees, 40 to 50 degrees, or approximately 45 degrees. These transitions and these angles are believed to create localized strain regions that act as stress concentrators. During use, absorbent articles tend to create smooth folds close to the stress concentrators, thus facilitating the adaptation of the article to the body in that position.
[041] The transition between the channel portion and the narrowing portion is also indicated by a distinctive change in curvature. For example, portions of channel 112 transition into narrowing portions 114 at a second convex transition 118 along both longitudinal edges 119. Second convex transition 118 may define any suitable angle 168. In some configurations, the angle 168 can be between 5 to 30 degrees, 10 to 20 degrees, or approximately 10 degrees. These transitions are also believed to create localized strain regions that act as stress concentrators. During use, the concave transitions 116 and the convex transitions 118 are believed to promote a smooth and controlled folding of the absorbent article at the location of the stress concentrators. This controlled folding further allows the absorbent article to conform to the wearer's body and allows the shaft portion, channel portion and necking portion to be properly aligned with the wearer's body.
[042] In some embodiments, the absorbent article 10 may have a perimeter 95 in any suitable shape as discussed above. For example, in some configurations, perimeter 95 may include a concave recess 102 in the back section of absorbent article 10, as illustrated in Figs. 2 and 4. In some configurations, the concave recess 102 may be substantially aligned with the longitudinal centerline of the body conformable structure 32 to promote a longitudinal peak in the back portion of the absorbent article 10 during use.
[043] Referring to Fig. 5, the body-adaptive structure 32 has a length of the first body-adaptive structure 70. Similarly, the body-side absorbent layer 28 has a body-side absorbent length 72, as illustrated in Fig. 4. In a first embodiment, the length of the body-side absorbent 72 may be between 160 to 190 mm, 170 to 180 mm, or approximately 175 mm. In these configurations, the length of the body adaptable structure 70 can be between 110 to 135 mm, 115 to 125 mm or approximately 120 mm. In a second configuration, the length of the body side absorbent 72 can be between 235 to 265 mm, 245 to 255 mm or approximately 250 mm. In these configurations, the length of the body adaptable structure 70 can be between 165 to 190 mm, 175 to 185 mm or approximately 180 mm. In a third configuration, the length of the body side absorbent 72 can be between 275 to 305 mm, 280 to 300 mm or approximately 290 mm. In these configurations, the length of the body adaptable structure 70 can be between 190 to 215 mm, 200 to 210 mm or approximately 205 mm. In a fourth configuration, the length of the body-side absorbent 72 can be between 325 to 355 mm, 335 to 345 mm, or approximately 340 mm. In these configurations, the length of the body adaptable structure 70 can be between 225 to 250 mm, 235 to 245 mm or approximately 240 mm. In various configurations, the length of the body-adaptive structure 70 can be at least 50%, at least 60%, or at least 70% of the length of the body-side absorbent 72. In some configurations, the length of the body-adaptive structure 70 can be 65 to 75% of the length of the body side absorbent 72.
[044] The body-adaptive frame 32 has a body-adaptive frame width. The width of the body-adaptive structure may be variable along the longitudinal centerline 50. For example, the body-adaptive structure 32 defines a median front portion width 74, a median center portion width 76, and a median rear portion width 78. As used herein, the term "median width" of a given portion is the numerical value that separates the upper half of the widths within a given portion from the lower half of the widths within the same portion. The median width can be determined by measuring the width of a given portion at 1 mm intervals along the longitudinal centerline, arranging the measured values in ascending order and then selecting the middle value. If an even number of measurements has been obtained, then the median width is the average between the two measurements that lie in the middle. In some configurations, the median width of the front portion 74 is greater than the median width of the central portion 76, which is greater than the median width of the posterior portion 78. In some configurations, the median width of the front portion 74 may be between 40 to 60mm, 45 to 55mm or approximately 52mm. In some configurations, the median width of the central portion 76 may be between 10 to 40 mm, 20 to 30 mm, or approximately 27 mm. In some configurations, the median width of the posterior portion 78 may be between 7 to 30 mm, 10 to 20 mm, or approximately 15 mm.
[045] The body side absorbent layer 28 also defines a minimum width 61. In the first configuration, the minimum width 61 can be between 40 to 65 mm, 45 to 60 mm or approximately 55 mm. In the second configuration, in the third configuration, and in the fourth configuration, the minimum width 61 can be between 50 to 75 mm, 55 to 65 mm or approximately 60 mm. In some configurations, the median width of the central portion 76 of the body-adaptive structure 32 is 25 to 50% of the minimum width 61 of the body-side absorbent layer 28. In some configurations, the median width of the central portion 76 of the body-adaptive structure body 32 is 40 to 45% of the minimum width 61 of the body side absorbent layer 28.
[046] The body-adaptive structure 32 defines a peripheral edge of the body-adaptive structure 33 which, in turn, defines an area of the body-adaptive structure 34. Similarly, the body-side absorbent layer 28 defines a perimeter outer 96 and outer perimeter 96 define an area of the body side absorbent 97. In the first embodiment, the area of the body side absorbent 97 can be between 90 to 110 cm2, 95 to 105 cm2 or approximately 100 cm2. In these configurations, the area of the body adaptable structure 34 can be between 30 to 40 cm2, 32 to 36 cm2 or approximately 34 cm2. In the second embodiment, the body side area of the absorbent 97 can be between 180 to 210 cm 2 , 190 to 200 cm 2 or approximately 195 cm 2 . In these configurations, the body adaptable structure 34 can be between 30 to 45 cm2, 35 to 40 cm2 or approximately 39 cm2. In the third configuration, the body side area of the absorbent 97 can be between 220 to 260 cm 2 , 230 to 250 cm 2 or approximately 240 cm 2 . In these configurations, the body adaptable structure 34 can be between 40 to 55 cm2, 45 to 50 cm2 or approximately 48 cm2. In the fourth configuration, the body side area of the absorbent 97 can be between 300 to 345 cm 2 , 310 to 335 cm 2 or approximately 325 cm 2 . In these configurations, the [area of] structure adaptable to the body 34 can be between 55 to 75 cm2, 60 to 70 cm2 or approximately 65 cm2. In various configurations, the area of the body-adaptive structure 34 may be at least 15%, at least 20%, or at least 30% of the area of the body-side absorbent 97. In some configurations, the body-adaptive structure 34 may be approximately 20% of the body side area of the absorbent 97.
[047] In some embodiments, the absorbent article of the present invention may also include a structure adaptable to the complementary body. For example, now referring to Fig. 6, an absorbent article 80 is illustrated. The absorbent article 80 includes a liquid-permeable upper lamina (also called a body-side liner) 20, a substantially liquid-impervious back lamina 22, and an absorbent body 24 positioned between the back lamina 22 and the upper lamina 20. In configuration illustrated, absorbent body 24 includes an absorbent pad 26 and a body-side absorbent layer 28. In other embodiments, absorbent body 24 may include a single layer or more than two layers, as discussed herein (not illustrated). The absorbent article 80 is also illustrated with containment tabs 40, containment elastics 42, containment tab carrier mat 44, garment attachment adhesive 46 and a detachable strip 48, all optional.
[048] The absorbent article 80 of Fig. 6 includes a body-adaptive structure 32 and a body-adaptive structure 82. Together, the body-adaptive structure 32 and the body-adaptive structure 82 define a body-adaptive structure 82. compound 88.
