Abstract

This invention provides an absorbent article configured for controlled deformation when worn by a user. The absorbent article includes a cover positionable adjacent the user, a barrier layer coupled to the cover and an absorbent layer interposed between the cover and the barrier layer. The absorbent layer of the present invention further defines at least two elongated gaps extending in a longitudinal direction, the gaps being laterally spaced on opposed sides of a centerline of the absorbent article, where each of the gaps defines a deformation zone to facilitate controlled deformation.

Claims

1. An absorbent article configured for controlled deformation when worn by a user, said absorbent article comprising:

a cover positionable adjacent the user;

a barrier layer coupled to said cover; and

an absorbent layer interposed between said cover and said barrier layer, said absorbent layer having at least two elongated gaps extending in a longitudinal direction and laterally spaced on opposed sides of a centerline of said absorbent layer, each of said gaps defining a deformation zone to facilitate said controlled deformation.

2. The absorbent article of claim 1, further comprising a fluid distribution layer interposed between said cover and said barrier layer.

3. The absorbent article of claim 1, said absorbent layer defining at least a first gap transverse to said longitudinal direction.

4. The absorbent article of claim 3, wherein said first gap is disposed in a front or a rear portion of said absorbent article and adjacent a crotch portion of said absorbent article.

5. The absorbent article of claim 4, further comprising a second gap disposed transverse to said longitudinal direction, wherein said second gap is disposed in a front or a rear portion opposite said first gap and adjacent said crotch portion of the absorbent article.

6. The absorbent article of claim 1, said absorbent layer comprising at least three elongated portions together defining said elongated gaps.

7. The absorbent article of claim 6, wherein said elongated gaps are channels.

8. The absorbent article of claim 1, said absorbent layer having only two elongated gaps extending in said longitudinal direction, each of said gaps defining a deformation zone to facilitate said controlled deformation.

9. The absorbent article of claim 8, said elongated gaps being spaced the same distance from said centerline of said absorbent layer.

10. The absorbent article of claim 1, at least one of said elongated gaps extending along a full length of said absorbent layer.

11. The absorbent article of claim 10, each of said elongated gaps extending along the full length of said absorbent layer.

12. The absorbent article of claim 10, said at least one elongated gap having open ends.

13. The absorbent article of claim 1, at least one of said elongated gaps extending less than a full length of said absorbent layer.

14. The absorbent article of claim 13, each of said elongated gaps extending less than the full length of said absorbent layer.

15. The absorbent article of claim 13, said at least one elongated gap having closed ends.

16. A method of donning an absorbent article on a user comprising the steps of:

deforming the absorbent article along at least two elongated gaps extending in a longitudinal direction of an absorbent layer, thereby producing a body-conforming configuration; and

fastening front and back portions of the absorbent article about a waist of the user.

17. The method of claim 16, said deforming step further comprising deforming the absorbent article along at least one gap in the absorbent layer transverse to the longitudinal direction of the absorbent layer.

18. The method of claim 17, said deforming step further comprising deforming the absorbent article along at least two gaps in the absorbent layer transverse to the longitudinal direction of the absorbent layer.

19. A method of making an absorbent article configured for controlled deformation when worn by a user, said method comprising the steps of:

defining at least two elongated gaps extending in a longitudinal direction of an absorbent layer and laterally spaced on opposed sides of a centerline of the absorbent layer, thereby forming deformation zones to facilitate the controlled deformation; and

interposing the absorbent layer between a cover and a barrier layer.

20. The method of claim 19, further comprising the step of interposing a fluid distribution layer between the cover and the barrier layer.

21. The method of claim 19, said defining step further comprising defining at least a first gap transverse to the longitudinal direction of the absorbent layer.

22. The method of claim 21, said defining step further comprising disposing the first gap in a front or a rear portion of the absorbent article and adjacent a crotch portion of the absorbent article.

23. The method of claim 22, said defining step further comprising disposing a second gap transverse to the longitudinal direction in a front or a rear portion opposite the first gap and adjacent the crotch portion of the absorbent article.

24. The method of claim 19, said defining step comprising defining only two elongated gaps extending in the longitudinal direction, each of the gaps forming a deformation zone to facilitate the controlled deformation.

25. The method of claim 24, said defining step comprising spacing the elongated gaps the same distance from the centerline of the absorbent layer.

26. The method of claim 19, said defining step comprising extending at least one of the elongated gaps along a full length of the absorbent layer.

27. The method of claim 26, said defining step comprising extending each of the elongated gaps along the full length of the absorbent layer.

28. The method of claim 19, said defining step comprising extending at least one of the elongated gaps less than a full length of the absorbent layer.

29. The method of claim 28, said defining step comprising extending each of the elongated gaps less than the full length of the absorbent layer.
