Abstract

A disposable absorbent article having barrier cuffs is disclosed herein. The disposable absorbent article has improved pad curl characteristics which can facilitate application of the disposable absorbent article.

First claim

What is claimed is:

1. A disposable absorbent article having a longitudinal axis and a lateral axis perpendicular to the longitudinal axis, the disposable absorbent article further comprising:
a chassis having first and second longitudinal side edges extending generally parallel to the longitudinal axis, a pair of end edges joining the first and second longitudinal side edges on opposite ends of the chassis, the chassis further comprising a topsheet; a backsheet; and an absorbent core disposed between the topsheet and the backsheet;
a fastening adhesive disposed on a garment-facing surface of the chassis;
a first cuff extending along the first longitudinal side edge; and
a second cuff extending along the second longitudinal side edge, wherein the article has a flexibility factor of less than 220 and an average pad curl of less than 3.0 mm.

2. The disposable absorbent article of claim 1 , wherein the average pad curl is less than 2 mm.

3. The disposable absorbent article of claim 1 , wherein an average cross directional peak load is less than 160 grams force.

4. The disposable absorbent article of claim 3 , wherein an average cross directional peak load is between about 30 to about 160 grams force.

5. The disposable absorbent article of claim 1 , wherein the first cuff and the second cuff comprise a portion of the topsheet and the backsheet.

6. The disposable absorbent article of claim 1 , wherein the first cuff comprises a first cover and the second cuff comprises a second cover, wherein first cover and second cover are discrete from the chassis of the absorbent article.

7. The disposable absorbent article of claim 6 , wherein the first cover and the second cover are attached to the topsheet.

8. The disposable absorbent article of claim 1 , wherein the flexibility factor is less than 212.

9. The disposable absorbent article of claim 1 , wherein the flexibility factor is between 50 and 220.

10. The disposable absorbent article of claim 1 , wherein the average pad curl is less than 2.0 mm.

11. The disposable absorbent article of claim 1 , wherein the average pad curl is between 0.5 mm and 2.5 mm.

12. The disposable absorbent article of claim 1 , wherein the average pad curl is between 1.0 mm and 2.0 mm.

13. The disposable absorbent article of claim 1 , wherein the average pad curl is between 0.5 mm and 3.0 mm.

14. A disposable absorbent article having a longitudinal axis and a lateral axis perpendicular to the longitudinal axis, the disposable absorbent article further comprising:
a chassis having first and second longitudinal side edges extending generally parallel to the longitudinal axis, a pair of end edges joining the first and second longitudinal side edges on opposite ends of the chassis, the chassis further comprising a topsheet; a backsheet; and an absorbent core disposed between the topsheet and the backsheet;
a fastening adhesive disposed on a garment-facing surface of the chassis;
a first cuff extending along the first longitudinal side edge; and
a second cuff extending along the second longitudinal side edge, wherein the article has a flexibility factor of less than 190 and an average pad curl of less than 4.0 mm.

15. The disposable absorbent article of claim 14 , wherein the average pad curl is less than 3.0 mm.

16. The disposable absorbent article of claim 14 , wherein the average pad curl is between 0.5 mm and 4.0 mm.

17. The disposable absorbent article of claim 14 , wherein the average pad curl is between 1.0 mm and 3.0 mm.

18. The disposable absorbent article of claim 14 , wherein the flexibility factor is less than 180.

19. The disposable absorbent article of claim 14 , wherein the flexibility factor is between 50 and 190.

20. The disposable absorbent article of claim 14 , wherein the first cuff and the second cuff comprise a portion of the topsheet and the backsheet.

21. The disposable absorbent article of claim 14 , wherein the first cuff comprises a first cover and the second cuff comprises a second cover, wherein first cover and second cover are discrete from the chassis of the absorbent article.

22. The disposable absorbent article of claim 21 , wherein the first cover and the second cover are attached to the topsheet.

23. A disposable absorbent article having a longitudinal axis and a lateral axis perpendicular to the longitudinal axis, the disposable absorbent article further comprising:
a chassis having first and second longitudinal side edges extending generally parallel to the longitudinal axis, a pair of end edges joining the first and second longitudinal side edges on opposite ends of the chassis, the chassis further comprising a topsheet; a backsheet; and an absorbent core disposed between the topsheet and the backsheet;
a fastening adhesive disposed on a garment-facing surface of the chassis;
a first cuff extending along the first longitudinal side edge; and
a second cuff extending along the second longitudinal side edge, wherein the article has an average pad curl (APC) that satisfies the following equation:
APC≤(−0.0338FF+8.7879)

wherein APC is in mm and FF is a flexibility factor of the article.

24. The disposable absorbent article of claim 23 , wherein the first cuff and the second cuff comprise a portion of the topsheet and the backsheet.

25. The disposable absorbent article of claim 23 , wherein the first cuff comprises a first cover and the second cuff comprises a second cover, wherein first cover and second cover are discrete from the chassis of the absorbent article.

26. The disposable absorbent article of claim 25 , wherein the first cover and the second cover are attached to the topsheet.

27. The disposable absorbent article of claim 23 , wherein the average pad curl is less than 9.0 mm.

28. The disposable absorbent article of claim 27 , wherein the average pad curl is between 0.5 mm and 9.0 mm.

29. The disposable absorbent article of claim 23 , wherein the average pad curl is less than 7.0 mm.

30. The disposable absorbent article of claim 29 , wherein the average pad curl is between 0.5 mm and 7.0 mm.

31. The disposable absorbent article of claim 23 , wherein the average pad curl is between 0.5 mm and 3.0 mm.

32. The disposable absorbent article of claim 23 , wherein the flexibility factor is less than 260.

33. The disposable absorbent article of claim 23 , wherein the flexibility factor is less than 240.
