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:

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;
a plurality of elastic strands disposed at least partially intermediate the first substrate and the second substrate, wherein portions of the elastic strands are joined to the first substrate, wherein the second substrate is joined to the first substrate or to portions of the elastic strands, and wherein the elastic strands have an elastic strand spacing in the range of about 0.5 mm to about 3 mm, according to the Rugosity Length, Rugosity Frequency, Rugosity Amplitude, Elastic Element Spacing, and Texture Ratio Method described herein;
a background pattern comprising a first plurality of rugosities formed in the first substrate, wherein the first plurality of the rugosities have a first frequency range and a first amplitude range, and wherein the first plurality of rugosities have a minimum amplitude of 0.25 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, higher frequency range and a second, smaller amplitude range, and wherein the second plurality of the rugosities have a minimum amplitude of 0.25 mm;
wherein the plurality of discrete texture areas are positioned only within the background pattern;
wherein a portion of the first substrate is nested with a portion of the second substrate in the first plurality of rugosities or in the second plurality of rugosities.

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

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 strands; and
a second adhesive pattern of elements on the second substrate and adhesively engaging a second portion of the one or more elastic strands.

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 3 , wherein the elements of the first adhesive pattern have a first size, wherein the elements of the second adhesive pattern have a second size, and wherein the first size is the same as the second size.

6. The absorbent article of claim 3 , wherein the elements of the first adhesive pattern have a first shape, wherein the elements of the second adhesive pattern have a second shape, and wherein the first shape is the same as the second shape.

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

8. The absorbent article of claim 1 , wherein a first pattern of densified regions in the first substrate is different than a second pattern of densified regions in the second substrate.

9. The absorbent article of claim 1 , 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.

10. The absorbent article of claim 1 , wherein the background pattern 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.

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

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

13. An absorbent article comprising:
a longitudinal axis;
a core;
a first substrate;
a second substrate;
one or more elastic strands disposed at least partially intermediate the first substrate and the second substrate, wherein the second substrate is attached to the first substrate and/or portions of one or more of the elastic strands, and wherein the elastic strands have an elastic strands spacing in the range of about 0.5 mm to about 3 mm, according to the Rugosity Length, Rugosity Frequency, Rugosity Amplitude, Elastic Element Spacing, and Texture Ratio Method described herein;
a pattern of discrete adhesive elements disposed on the first substrate;
a plurality of discrete texture areas each comprising a first portion of the substrates, a first portion of the one or more elastic strands, and one or more of the discrete adhesive elements, wherein at least some of the discrete texture areas comprise a first plurality of rugosities, and wherein the substrates are nested within the first plurality of rugosities;
a background pattern comprising a second portion of the substrates, a second portion of the one or more elastic strands, wherein the second portion of the substrates and the second portion of the one or more elastic strands within the background pattern are free of the pattern of discrete adhesive elements, and wherein the background pattern comprises a second plurality of rugosities; and
wherein the plurality of discrete texture areas are positioned only within the background pattern.

14. The absorbent article of claim 13 , wherein the background pattern is free of the discrete adhesive elements and comprises portions that are angled relative to the longitudinal axis.

15. The absorbent article of claim 13 , wherein the first plurality of rugosities have a first frequency range and a first amplitude range in the first portion of the substrates, wherein the second plurality of rugosities have a second frequency range and a second amplitude range in the second portion of the substrates, wherein the first frequency range is different than the second frequency range, and wherein the first amplitude range is different than the second amplitude range.

16. The absorbent article of claim 13 , wherein the one or more elastic strands are intermittently bonded to at least one of the substrates.

17. The absorbent article of claim 13 , wherein the background pattern forms a repeating diamond pattern in which the discrete texture areas are positioned.
