Abstract

A disposable absorbent article, such as a disposable diaper, having barrier leg cuffs. The barrier leg cuffs have a distal edge which is spaced from the proximal edge so as to provide a barrier against leakage. The barrier leg cuff has a portion affixed to the diaper so that the spacing between the barrier leg cuffs is increased in selected portions to reduce irritation of the genetalia and to provide a larger area to receive bodily discharges.

Claims

1. A unitary disposable absorbent article comprising:

a liquid permeable topsheet;

a liquid impermeable backsheet affixed to said topsheet;

an absorbent means for absorbing liquids, said absorbent means being encased between said topsheet and said backsheet;

a first end, a second end opposed to said first end, a first longitudinal side and a second longitudinal side;

a barrier leg cuff corresponding to each of said first and second longitudinal sides, each said barrier leg cuff having a proximal edge affixed to the absorbent article, a distal edge spaced from said proximal edge, and an attachment zone disposed between said proximal edge and said distal edge, said attachment zone being affixed to the absorbent article in an area between said the portion of said barrier cuffs that is between said attachment zone and said proximal edges and said longitudinal side corresponding to said attachment zone so as to increase the lateral spacing between said distal edges along a portion of the length of the absorbent article; and

a spacing means operatively associated with each said barrier leg cuff in an elastically contractible condition for spacing said distal edge away from said proximal edge

2. The disposable absorbent article of claim 1 wherein said attachment zone is positioned along the length of said barrier cuff from about 150 mm to about 380 mm from said first end.

3. The disposable absorbent article of claim 2 wherein said attachment zone is positioned along the length of said barrier leg cuff from about 200 mm to about 340 mm from said first end.

4. The disposable absorbent article of claim 2 wherein said attachment zone is positioned along the length of said barrier leg cuff from about 250 mm to about 380 mm from said first end.

5. The disposable absorbent article of claim 2 wherein said attachment zone is positioned along the length of said barrier leg cuff from about 150 mm to about 300 mm from said first end.

6. The disposable absorbent article of claim 1 wherein the width of each said barrier leg cuff is from about 5 mm to about 90 mm.

7. The disposable absorbent article of claim 6 wherein the width of each of said barrier cuffs is from about 20 mm to about 60 mm.

8. The disposable absorbent article of claim 1 wherein said spacing means is a spacing elastic member.

9. The disposable absorbent article of claim 1 wherein said attachment zone is affixed to an area of said barrier leg cuff between said (attachment zone) and said proximal edge.

10. The disposable absorbent article of claim 1 further comprising an elastically contractible gasketing cuff along each of said first and second longitudinal sides, each said elastically contractible gasketing cuff comprising a longitudinal marginal portion and an elastic member operatively associated in an elastically contractible condition with said longitudinal marginal portion.

11. The disposable absorbent article of claim 10 wherein each said elastically contractible gasketing cuff comprises an elastic member operatively associated with a longitudinal marginal portion.

12. The disposable absorbent article of claim 1 wherein said attachment zone is affixed to the absorbent article in an area between said proximal edge and said corresponding longitudinal side.

13. The disposable absorbent article of claim 1 wherein said proximal edge is disposed between said absorbent means and said longitudinal side.

14. The disposable absorbent article of claim 1 wherein said barrier leg cuff is liquid impermeable.

15. The disposable absorbent article of claim 1 wherein said barrier leg cuff is integral with said topsheet.

16. The disposable absorbent article of claim 1 wherein said barrier leg cuff is unitary with said topsheet.

17. A unitary disposable diaper comprising:

a liquid permeable topsheet;

a liquid impermeable backsheet affixed to said topsheet;

an absorbent means for absorbing liquids, said absorbent means being encased between said topsheet and said backsheet;

a first end, a second end opposed to said first end, a first longitudinal side and a second longitudinal side;

a barrier leg cuff corresponding to each of said first and second longitudinal sides, each said barrier leg cuff having a proximal edge affixed to the absorbent article, a distal edge spaced from said proximal edge, and an attachment zone disposed between said proximal edge and said distal edge, said attachment zone being affixed to the diaper in an area between said the portion of said barrier cuffs that is between said attachment zone and said proximal edges and said longitudinal side corresponding to said attachment zone so as to increase the lateral spacing between said distal edges along a portion of the length of the diaper, said attachment zone being positioned along the length of said barrier leg cuff from about 150 mm to about 380 mm from said first end, and the width of each of said barrier leg cuffs being from about 5 mm to about 90 mm; and

a spacing elastic member operatively associated in an elastically contractible condition with each said barrier cuff for spacing said distal edge away from said proximal edge.

18. The disposable diaper of claim 17 additionally comprising an adhesive means for reducing the possibility of inversion of said distal edges of said barrier leg cuffs during application and use, said adhesive means being disposed in both said first end and said second end of the diaper.

19. The disposable diaper of claim 18 wherein said barrier leg cuff is integral with said topsheet.

20. The disposable diaper of claim 19 wherein said attachment zone is affixed to an area of said barrier leg cuff between said attachment zone and said proximal edge.

21. The disposable diaper of claim 19 wherein said attachment zone is affixed to the diaper in an area between said proximal edge and said corresponding longitudinal side.

22. The disposable diaper of claim 21 additionally comprising an elastically contractible gasketing cuff along each of said first and second longitudinal sides, each said elastically contractible gasketing cuff comprising a longitudinal marginal portion and an elastic member operatively associated in an elastically contractible condition with said longitudinal marginal portion, said attachment zone being affixed to the diaper in an area between said proximal edge and said elastic member of said gasketing cuff.

23. The disposable diaper of claim 22 wherein said barrier leg cuff is liquid impermeable.
