Abstract

A disposable diaper having a waist pocket cuff is disclosed. The pocket cuff has an open edge having an apex. The open edge extends between ends joined to the distal edges of barrier cuffs. The open edge is elastically biased to form the open edge apex along the longitudinal centerline of the disposable diaper.

Claims

1. A disposable absorbent article having a front waist region, a rear waist region longitudinally spaced from the front waist region, a crotch region disposed between the front and rear waist regions, longitudinal edges, end edges, a longitudinal centerline and a lateral centerline, the disposable absorbent article comprising:

a liquid pervious topsheet;

a liquid impervious backsheet joined to the topsheet;

an absorbent core positioned between the topsheet and the backsheet, the absorbent core having side edges and front and rear waist edges;

a side flap extending laterally outward from each side edge of the absorbent core;

a fastening means for securing the disposable absorbent article on the wearer;

a barrier cuff disposed adjacent each longitudinal edge of the disposable absorbent article, each barrier cuff extending longitudinally from a first barrier cuff end in the front waist region to a second barrier cuff end in the rear waist region, and each barrier cuff having a proximal edge and a distal edge, each proximal edge joined to a side flap, each barrier cuff being inflected to have the distal edge extending laterally inward of the proximal edge at the first barrier cuff end and the distal edge extending laterally outward of the proximal edge at the second barrier cuff end;

spacing means operatively associated with each barrier cuff for spacing a portion of each barrier cuff distal edge apart from the topsheet; and

a pocket cuff positioned intermediate the barrier cuffs and operatively associated with the fastening means, the pocket cuff having an open edge extending intermediate the inflected barrier cuffs.

2. The disposable absorbent article of claim 1 wherein the open edge end extends intermediate laterally spaced apart open edge ends, and wherein each open edge end is joined to a barrier cuff at a juncture positioned intermediate the first and second barrier cuff ends.

3. The disposable absorbent article of claim 2 wherein the open edge has an apex positioned intermediate the open edge ends, the apex disposed longitudinally rearward of a line passing through the open edge ends.

4. The disposable absorbent article of claim 3 wherein the apex is positioned substantially on the longitudinal centerline of the disposable absorbent article.

5. The disposable absorbent article of claim 3 wherein the apex is positioned substantially equidistant from the open edge ends.

6. The disposable absorbent article recited in claim 1 wherein the pocket cuff is elastically extensible intermediate the pocket cuff open edge ends.

7. The disposable absorbent article recited in claim 6 wherein the pocket cuff open edge is elastically extensible intermediate the apex and each of the pocket cuff open edge ends.

8. The disposable absorbent article recited in claim 7 wherein the pocket cuff open edge comprises an elastic member extending intermediate the open edge ends.

9. The disposable absorbent article recited in claim 3 wherein a portion of the pocket cuff is joined to an underlying portion of the disposable absorbent article to elastically extend the open edge of the pocket cuff and to position the apex longitudinally rearward of the open edge ends.

10. The disposable absorbent article recited in claim 3 wherein a distal edge of a barrier cuff extends longitudinally rearward and laterally outward from each juncture.

11. The disposable absorbent article recited in claim 10 wherein said fastening means comprises a pair of fastening members, and wherein the distal edge of a barrier cuff extends intermediate a juncture and a fastening member.

12. The disposable absorbent article recited in claim 3 comprising an elastic member for biasing each pocket cuff open edge end longitudinally rearward and laterally outward.

13. The disposable absorbent article recited in claim 12 further comprising an elastic member for biasing each pocket cuff open edge end longitudinally rearward and laterally inward.

14. The disposable absorbent article recited in claim 13 further comprising an elastic member for biasing the pocket cuff open edge apex longitudinally rearward.
