Abstract

A disposable absorbent article may include a chassis that includes a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet; and a leg gasketing system and a waist gasketing element. The leg gasketing system may include an inner cuff and an outer cuff; the inner cuff may include an inner cuff folded edge and an inner cuff material edge and the outer cuff may include an outer cuff folded edge and an outer cuff material edge such that the web of material is folded laterally inward to form the outer cuff folded edge and folded laterally outward to form the inner cuff folded edge. The leg gasketing system may also include a leg gasketing system pocket with an opening on an inboard longitudinal edge of the pocket.

First claim

What is claimed is:

1 . A disposable absorbent article for wearing about the lower torso of a wearer, the disposable absorbent article comprising: a first waist region, a second waist region, a crotch region disposed between the first and second waist regions; a first waist edge and a second waist edge; and a first longitudinal edge and a second longitudinal edge; wherein the disposable absorbent article comprises a chassis comprising:
1.) a topsheet; 2.) a backsheet; and 3.) an absorbent core disposed between the topsheet and the backsheet; wherein the disposable absorbent article further comprises a leg gasketing system and at least one waist gasketing element; wherein the leg gasketing system comprises a web of material forming an inner cuff and an outer cuff; wherein the inner cuff comprises an inner cuff folded edge and an inner cuff material edge and the outer cuff comprises an outer cuff folded edge and an outer cuff material edge, such that the web of material is folded laterally inward to form the outer cuff folded edge and folded laterally outward to form the inner cuff folded edge; wherein at least a portion of the web of material between the outer cuff folded edge and the outer cuff material edge is attached to the chassis in the first waist region, the second waist region and the crotch region; and at least a portion of the web of material between the inner cuff folded edge and the outer cuff folded edge is attached to the web of material between the outer cuff folded edge and the outer cuff material edge in the crotch region and the first waist region; and the web of material between the inner cuff folded edge and the outer cuff folded edge is unattached to the web of material between the outer cuff folded edge and the outer cuff material edge in at least a portion of the second waist region, forming a leg gasketing system pocket with an opening on an inboard longitudinal edge of the leg gasketing system pocket; wherein the at least one waist gasketing element has an inboard lateral edge, an outboard lateral edge, and two longitudinal edges; the at least one waist gasketing element comprising at least one elastic material; wherein the at least one waist gasketing element is attached to: 1) the chassis of the disposable absorbent article and 2) the leg gasketing system, such that at least a portion of the outboard lateral edge of the waist gasketing element is attached to the chassis and at least a portion of the outboard lateral edge of the waist gasketing element is attached to the web of material forming the leg gasketing system; and wherein the inboard lateral edge of the waist gasketing element is unattached to the chassis of the disposable absorbent article.

2 . The disposable absorbent article of claim 1 , wherein the at least one elastic material of the waist gasketing element is an elastic strand.

3 . The disposable absorbent article of claim 2 , wherein the waist gasketing element comprises at least four elastic strands.

4 . The disposable absorbent article of claim 1 , wherein the at least one elastic material of the waist gasketing element is an elastic film or an elastomeric nonwoven.

5 . The disposable absorbent article of claim 1 , wherein the outboard lateral edge of the waist gasketing element is coterminous with the second waist edge of the disposable absorbent article.

6 . The disposable absorbent article of claim 1 , wherein at least a portion of the inboard lateral edge of the waist gasketing element is attached to the leg gasketing system.

7 . The disposable absorbent article of claim 1 , wherein at least a portion of each of the two longitudinal edges of the waist gasketing element are attached to the leg gasketing system.

8 . The disposable absorbent article of claim 1 , wherein an entire length of each of the two longitudinal edges of the waist gasketing element are attached to the leg gasketing system.

9 . The disposable absorbent article of claim 1 , wherein the waist gasketing element is attached to leg gasketing system over substantially an entire area that the leg gasketing system overlaps with the waist gasketing element.

10 . The disposable absorbent article of claim 1 , wherein the at least one elastic material of the waist gasketing element is only partially extended when the respective waist region is fully extended.

11 . The disposable absorbent article of claim 1 , wherein the opening of the leg gasketing system pocket measures between about 5 mm and about 100 mm in the longitudinal direction.

12 . The disposable absorbent article of claim 1 , wherein the leg gasketing system pocket has an overall longitudinal length of between about 5 mm and about 200 mm in the longitudinal direction.

13 . The disposable absorbent article of claim 1 , wherein the opening of the leg gasketing system pocket is between about 1% and about 75% of the overall longitudinal length of the leg gasketing system pocket.

14 . The disposable absorbent article of claim 1 , wherein the leg gasketing system pocket is free of elastic members.

15 . The disposable absorbent article of claim 1 , wherein the leg gasketing system pocket contains one or more snap back elastic members.

16 . The disposable absorbent article of claim 1 , wherein at least a portion of the web of material between the outer cuff folded edge and the outer cuff material edge is attached to the topsheet and/or backsheet in the first waist region, the second waist region and the crotch region.

17 . The disposable absorbent article of claim 1 , wherein in the chassis comprises an opacity strengthening patch, and wherein at least a portion of the web of material between the outer cuff folded edge and the outer cuff material edge is attached to the opacity strengthening patch in the first waist region, the second waist region and the crotch region.

18 . The disposable absorbent article of claim 1 , wherein the inner cuff has an opacity of from about 15% to about 50% hunter opacity and the outer cuff has an opacity of from about 45% to about 75% hunter opacity.

19 . The disposable absorbent article of claim 1 , wherein the inner cuff has an air permeability of less than about 50 m 3 /m 2 /min and the outer cuff has an air permeability of greater than about 5 m 3 /m 2 /min.

20 . The disposable absorbent article of claim 1 , wherein the inner cuff has a WVTR of less than about 5500 g/m 2 /24 hrs and the outer cuff has a WVTR of greater than about 4250 g/m 2 /24 hrs.

21 . The disposable absorbent article of claim 1 , wherein the leg gasketing system extends from the first waist edge to the second waist edge.
