Abstract

An absorbent article comprises first and second substrates and one or more elastic elements disposed at least partially intermediate the substrates. The second substrate is attached to the first substrate and/or to portions of the elastic elements. The absorbent article comprises an adhesive having a first and second pattern of elements disposed on first substrate, and first and second texture zones. The first texture zone comprises a first portion of the substrates, a first portion of the elastic elements, and the first pattern of elements of the adhesive and forms a background pattern in the first portion of the substrates. The second texture zone comprises a second portion of the substrates, a second portion of the one or more elastic elements, and the second pattern of elements of the adhesive and forms a macro pattern in the second portion of the substrates.

First claim

What is claimed is:

1. An absorbent article comprising:
a chassis comprising:
a topsheet;
a backsheet; and
a core disposed at least partially intermediate the topsheet and the backsheet; and

a belt portion extending from the chassis, the belt portion comprising:
a first substrate;
a second substrate;
one or more elastic elements disposed at least partially intermediate the first substrate and the second substrate, wherein portions of the elastic elements are joined to the first substrate, and wherein the second substrate is joined to the first substrate or to portions of the elastic elements;
a continuous texture grid comprising a first plurality of rugosities formed in the first substrate, wherein the first plurality of the rugosities have a first frequency range, and wherein the first plurality of rugosities have a minimum amplitude of 1 mm; and
a plurality of discrete texture areas each comprising a second plurality of rugosities formed in the first substrate, wherein the second plurality of the rugosities have a second, different frequency range, wherein a first frequency in the first frequency range is at least two times different than a second frequency in the second, different frequency range, and wherein the second plurality of the rugosities have a minimum amplitude of 1 mm;
wherein the plurality of discrete texture areas are positioned within the continuous texture grid.

2. The absorbent article of claim 1 , wherein the first substrate comprises a first nonwoven substrate, wherein the second substrate comprises a second nonwoven substrate, and wherein the elastic elements comprise elastic strands.

3. The absorbent article of claim 1 , wherein the belt portion comprises:
a first adhesive pattern of elements on the first substrate and adhesively engaging a first portion of the one or more elastic elements; and
a second adhesive pattern of elements on the second substrate and adhesively engaging a second portion of the one or more elastic elements.

4. The absorbent article of claim 3 , wherein the first adhesive pattern of elements is the same as the second adhesive pattern of elements.

5. The absorbent article of claim 4 , wherein a first pattern of densified regions in the first substrate is different than a second pattern of densified regions in the second substrate.

6. The absorbent article of claim 4 , wherein one of the substrates has a first pattern of densified regions and a second pattern of densified regions formed therein, and wherein the first pattern of densified regions is different than the second pattern of densified regions.

7. The absorbent article of claim 3 , wherein the first adhesive pattern of elements is different than the second adhesive pattern of elements.

8. The absorbent article of claim 7 , wherein a first pattern of densified regions in the first substrate is substantially the same as a second pattern of densified regions in the second substrate.

9. The absorbent article of claim 7 , wherein a first pattern of densified regions in the first substrate is different than a second pattern of densified regions in the second substrate.

10. The absorbent article of claim 7 , wherein one of the substrates has a first pattern of densified regions and a second pattern of densified regions, and wherein the first pattern of densified regions is different than the second pattern of densified regions.

11. The absorbent article of claim 3 , wherein the first adhesive pattern of elements comprises elements having a first size or shape, and wherein the second adhesive pattern of elements comprises elements having a second, different size or shape.

12. The absorbent article of claim 1 , wherein the continuous texture grid extends in a first direction and in a second, different direction, and wherein the plurality of discrete texture areas each form substantially the same polygonal shape.

13. The absorbent article of claim 1 , wherein an amplitude range of the first plurality of the rugosities of the continuous texture grid is different than an amplitude range of the second plurality of the rugosities of the plurality of discrete texture areas.

14. The absorbent article of claim 1 , wherein the belt portion is a front belt portion, comprising a rear belt portion extending from the chassis, and wherein the rear belt portion is longitudinally opposed to the front belt portion, the rear belt portion comprising:
a first substrate;
a second substrate;
one or more elastic elements disposed intermediate the first substrate and the second substrate, wherein portions of the elastic elements are joined to the first substrate, and wherein the second substrate is joined to the first substrate or to portions of the elastic elements;
a continuous texture grid comprising a third plurality of rugosities formed in the first substrate, wherein the third plurality of the rugosities have a first frequency range; and
a plurality of discrete texture areas each comprising a fourth plurality of rugosities formed in the first substrate, wherein the fourth plurality of the rugosities have a second, different frequency range.

15. The absorbent article of claim 14 , wherein portions of the front belt portion are permanently or releasably joined to portions of the rear belt portion to form a pant having a waist opening and two leg openings.

16. The absorbent article of claim 14 , wherein portions of the rear belt portion are configured to be joined to portions of the front belt portion using fasteners to form an absorbent article having a waist opening and two leg openings.

17. The absorbent article of claim 1 , wherein the belt portion comprises an adhesive forming a continuous pattern, wherein the continuous pattern extends in a first direction and in a second, different direction, and wherein lines of the continuous pattern of the adhesive extending in the first direction intersect with lines of the continuous pattern of the adhesive extending in the second, different direction.

18. The absorbent article of claim 17 , wherein the plurality of discrete texture areas are free of the continuous pattern of the adhesive.

19. The absorbent article of claim 1 , wherein at least some of the plurality of discrete texture areas form a diamond-like shape.

20. The absorbent article of claim 1 , wherein the second substrate within at least a portion of the first and second plurality of rugosities is nested with the first substrate.

21. The absorbent article of claim 1 , wherein the plurality of discrete texture areas are dispersed throughout the entire continuous texture grid.

22. An absorbent article comprising:
a core;
a first substrate;
a second substrate;
one or more elastic elements disposed at least partially intermediate the first substrate and the second substrate, wherein the second substrate is attached to any of the first substrate and portions of one or more of the elastic elements;
