Abstract

A disposable absorbent article may include a topsheet, a backsheet, an absorbent core disposed between the topsheet and the backsheet, and a leg gasketing system. 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 material edge.

Claims

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, the disposable absorbent article comprising;

1.) a topsheet;

2.) a backsheet;

3.) an absorbent core disposed between the topsheet and the backsheet; and

4.) a leg gasketing system, wherein the leg gasketing system comprises an inner cuff and an outer cuff;

wherein the inner cuff comprises an inner cuff folded edge and an inner cuff material edge;

wherein 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 material edge, wherein the leg gasketing system extends from the first waist edge to the second waist edge and is joined to the topsheet and/or backsheet between the inner cuff folded edge and the outer cuff folded edge in the crotch region.

2. The disposable absorbent article of claim 1, wherein the leg gasketing system does not comprise a polymeric film.

3. The disposable absorbent article of claim 1, wherein the leg gasketing system comprises an N-fiber material.

4. The disposable absorbent article of claim 1, wherein the inner leg cuff has a hydrostatic head of greater than about 2 mbar and the outer leg cuff has a hydrostatic head of less than about 200 mbar.

5. The disposable absorbent article of claim 1, wherein the inner leg cuff has a Low Surface Tension Fluid Strikethrough Time of greater than about 15 seconds and less than about 200 seconds and the outer leg cuff has a Low Surface Tension Fluid Strikethrough Time of greater than about 20 seconds and less than about 200 seconds.

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

7. The disposable absorbent article of claim 1, wherein the inner leg cuff has an air permeability of less than about 50 m³/m²/min and the outer leg cuff has an air permeability of greater than about 5 m³/m²/min.

8. The disposable absorbent article of claim 1, wherein the inner leg cuff has a WVTR of less than about 5500 g/m²/24 hrs and the outer leg cuff has a WVTR of greater than about 4250 g/m²/24 hrs.

9. The disposable absorbent article of claim 1, wherein the leg gasketing system comprises at least two elastic members on the inner barrier leg cuff.

10. The disposable absorbent article of claim 1, wherein the leg gasketing system comprises at least three elastic members on the outer leg cuff.

11. The disposable absorbent article of claim 1, wherein the leg gasketing system is comprised of one web of material.

12. The disposable absorbent article of claim 1, wherein the outer cuff material edge is disposed laterally inboard the inner cuff material edge.

13. The disposable absorbent article of claim 1, wherein elastic members are located between the inner cuff material edge and the outer cuff folded edge.

14. The disposable absorbent article of claim 1, wherein elastic members are located between the inner cuff folded edge and outer cuff material edge.

15. The disposable absorbent article of claim 1, wherein the outer cuff folded edge is located laterally outboard of the chassis edge in the crotch region.

16. The disposable absorbent article of claim 1, wherein the leg gasketing system is spaced laterally inward of the outermost longitudinal edge by at least about 10 mm.

17. 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, the disposable absorbent article comprising;

1.) a topsheet;

2.) a backsheet;

3.) an absorbent core disposed between the topsheet and the backsheet; and

4.) a leg gasketing system, wherein the leg gasketing system comprises an inner cuff and an outer cuff;

wherein the inner cuff comprises an inner cuff folded edge and an inner cuff material edge;

wherein 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, folded laterally outward to form the inner barrier leg cuff and back fold edge, and folded laterally inward to form the inner cuff folded edge,

wherein the leg gasketing system extends from the first waist edge to the second waist edge and is joined to the topsheet and/or backsheet in the crotch region.

18. The disposable absorbent article of claim 17, wherein the topsheet is not attached to the leg gasketing system.

19. The disposable absorbent article of claim 17, wherein the backsheet is attached to the leg gasketing system between the outer cuff material edge and the topsheet.

20. The disposable absorbent article 17, wherein the inner barrier leg cuff is two layers.
