Abstract

A disposable absorbent article comprising a chassis having a longitudinal centerline and an outwardly-facing surface and an inwardly-facing surface, the chassis adapted to extend from a back waist area of a wearer to a front waist area of a wearer with the inwardly-facing surface overlying the crotch area of the wearer, the chassis including a first front waist region, a second back waist region and a crotch region; and a fastening system comprising at least one first fastening element and a landing member engagable with the at least one first fastening element on opposing waist regions wherein the landing member has a top edge and a bottom edge wherein at least the top edge is nonlinear and provided with a multitude of upstanding features.

Claims

1. A disposable absorbent article comprising:

(a) a chassis having a longitudinal centerline and an outwardly-facing surface and an inwardly-facing surface, the chassis adapted to extend from a back waist area of a wearer to a front waist area of a wearer with the inwardly-facing surface overlying the crotch area of the wearer, the chassis including a first back waist region, a second front waist region and a crotch region; and

(b) a fastening system comprising at least one first fastening element and a landing member engagable with the at least one first fastening element on opposing waist regions wherein the landing member has a top edge and a bottom edge wherein at least the top edge is nonlinear and provided with a multitude of features.

2. The disposable absorbent article of claim 1 wherein the landing member is on the second front waist region.

3. The disposable absorbent article of claim 2 wherein the landing member is centered on the longitudinal centerline.

4. The disposable absorbent article of claim 3 wherein the landing member features are generally symmetrically arranged on either side of the centerline.

5. The disposable absorbent article of claim 2 wherein the features are a series of peaks and valleys.

6. The disposable absorbent article of claim 2 wherein the landing member has a continuous backing.

7. The disposable absorbent article of claim 2 wherein the landing member has a tensile strength of at least 0.5 kg/2.54 cm.

8. The disposable absorbent article of claim 6 wherein the landing member has a tensile strength of at least 1.0 kg/2.54 cm.

9. The disposable absorbent article of claim 6 wherein the features are spaced at a distance of at least 2 mm.

10. The disposable absorbent article of claim 2 wherein the features are spaced at a distance of from 5 to 100 mm.

11. The disposable absorbent article of claim 9 wherein the features have a height of at least 2 mm.

12. The disposable absorbent article of claim 10 wherein the features have a height of at least 3 mm.

13. The disposable absorbent article of claim 11 wherein the ratio of the height of the features to the width between the peaks is from 0.02 to 10.

14. The disposable absorbent article of claim 12 wherein the ratio of the height of the features to the width between the peaks if from 0.03 to 5.0.

15. The disposable absorbent article of claim 13 wherein the features have radii of curvature of greater than 2 mm.

16. The disposable absorbent article of claim 14 wherein the features have radii of curvature of greater than 3 mm.

17. The disposable absorbent article of claim 2 wherein the landing member bottom edge has features.

18. The disposable absorbent article of claim 2 wherein the width of the landing member is generally greater than or equal to the width of the fastening element.

19. The disposable absorbent article of claim 2 wherein the landing member has a Gurley Stiffness of from 6 to 500.

20. The disposable absorbent article of claim 6 wherein the landing member has a Gurley Stiffness of from 10 to 500.

21. The disposable absorbent article of claim 20 wherein the landing member has a compression stiffness of less than 700 grams.

22. The disposable absorbent article of claim 2 wherein the height of the features is from 5 to 50 percent of the maximum landing member width.

23. The disposable absorbent article of claim 6 wherein the height of the features is from 10 to 40 percent of the maximum landing member width.

24. The disposable absorbent article of claim 22 wherein the height of the features is greater than 2 mm.

25. The disposable absorbent article of claim 23 wherein the height of the features is greater than 3 mm.

26. The disposable absorbent article of claim 24 wherein the features reduce the compression resistance of at least a portion of the landing member top edge by at least 15 percent.

27. The disposable absorbent article of claim 24 wherein the features reduce the compression resistance of at least a portion of the landing member top edge by at least 30 percent.

28. The disposable absorbent article of claim 24 wherein the features reduce the compression resistance of at least a portion of the landing member top edge by at least 50 percent.

29. The disposable absorbent article of claim 2 wherein the features are irregular in size and shape.

30. The disposable absorbent article of claim 4 wherein the features are irregular.

31. The disposable absorbent article claim 30 wherein the features size and shape are symmetrical on either side of the centerline.
