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 material edge such that the web of material is folded outward to form the inner cuff folded edge. When tested by the Blowout Method Test as described herein, the disposable absorbent article has a Blowout Percent Leakage of less than about 9.0%.

Claims (26)

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:

a topsheet;

a backsheet; and

an absorbent core disposed between the topsheet and the backsheet;

wherein the disposable absorbent article comprises a leg gasketing system and a 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 wherein the outer cuff comprises an outer cuff material edge, such that the web of material is folded laterally outward to form the inner cuff folded edge;

wherein at least a portion of the web of material between the outer cuff material edge and the inner cuff folded 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 inner cuff material edge is attached to the topsheet in the first waist region;

wherein the waist gasketing element has an inboard lateral edge, an outboard lateral edge, and two longitudinal edges, wherein at least a portion of the waist gasketing element proximate to the outboard lateral edge is attached to the chassis, wherein at least a portion of the waist gasketing element proximate to the outboard lateral edge is attached to a portion of the leg gasketing system, wherein at least a portion of the waist gasketing element overlaps a portion of the leg gasketing system, wherein a portion of the inboard lateral edge of the waist gasketing element is unattached to the chassis thereby forming a waist gasketing element pocket, and wherein the waist gasketing element comprising at least one elastic member; and

wherein when tested by a Blowout Method Test as described herein, the disposable absorbent article has a Blowout Percent Leakage of less than 9.0%.

2. The disposable absorbent article of claim 1 , wherein the Blowout Percent Leakage is less than 7.0%.

3. The disposable absorbent article of claim 1 , wherein the Blowout Percent Leakage is less than 5.0%.

4. The disposable absorbent article of claim 1 , wherein an overall longitudinal length of the waist gasketing element pocket is between about 5 mm and about 100 mm.

5. The disposable absorbent article of claim 1 , wherein an overall lateral width of the waist gasketing element is between about 60 mm and about 200 mm.

6. The disposable absorbent article of claim 1 , wherein the waist gasketing element comprises at least two elastic members.

7. The disposable absorbent article of claim 1 , wherein the waist gasketing element comprises at least four elastic members.

8. The disposable absorbent article of claim 1 , wherein the inboard lateral edge of the waist gasketing element is a folded edge.

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

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

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

12. The disposable absorbent article of claim 1 , wherein the at least one of the leg gasketing system and the at least one waist gasketing element comprises an N-fiber material.

13. The disposable absorbent article of claim 1 , wherein the waist gasketing element pocket comprises a hydrophobic coating.

14. The disposable absorbent article of claim 1 , having an Efficiency Factor is less than 40.0.

15. The disposable absorbent article of claim 1 , having an Efficiency Factor is between about 0.1 and about 25.0.

16. The disposable absorbent article of claim 1 , wherein at least a portion of the waist gasketing element disposed between the inboard lateral edge and the outboard lateral edge is attached to the topsheet and/or the backsheet.

17. The disposable absorbent article of claim 1 , wherein at least a portion of the web of material between the inner cuff folded edge and the inner cuff material edge is attached to the topsheet in the second waist region.
