Abstract

A disposable absorbent article is provided having an absorbent core located in a chassis and including absorbent particulate polymer material defining at least one cavity. The absorbent core may be substantially cellulose free or comprise a combination of particulate absorbent polymer material and wood pulp. Methods for making such an absorbent core and corresponding disposable absorbent article are also disclosed.

Claims (52)

1. An absorbent article, comprising:

a front waist region;

a back waist region;

a crotch region positioned between the front waist region and the back waist region;

a topsheet;

a backsheet;

an absorbent core disposed between the topsheet and the backsheet, the absorbent core comprising absorbent particulate polymer material and wood pulp; and

wherein a cavity is defined in the absorbent core;

wherein absorbent particulate polymer material is present in the cavity;

wherein the cavity comprises a first channel extending in a first direction;

wherein the cavity comprises a second channel extending in a second, different direction;

wherein the first direction is transverse to the second direction, and

wherein a portion of the first channel overlaps a portion of the second channel;

wherein the cavity is discrete and is defined in and bounded by absorbent zones; and

wherein the absorbent particulate polymer material in the cavity has a lower basis weight than other absorbent particulate polymer material in the absorbent core and not in the cavity.

2. The absorbent article of claim 1 , wherein a first portion of the first channel is formed in the same area in the cavity as a first portion of the second channel in the cavity.

3. The absorbent article of claim 1 , wherein a first portion of the first channel overlaps a first portion of the second channel.

4. The absorbent article of claim 3 , wherein a second portion of the first channel is free from overlap with a second portion of the second channel.

5. The absorbent article of claim 4 , wherein the first channel has a positive slope with respect to a central longitudinal axis of the absorbent article.

6. The absorbent article of claim 5 , wherein the second channel has a negative slope with respect to the central longitudinal axis of the absorbent article.

7. The absorbent article of claim 1 , wherein the first channel has substantially the same length as the second channel.

8. The absorbent article of claim 7 , wherein at least a portion of the first channel has substantially the same width as at least a portion of the second channel.

9. The absorbent article of claim 1 , wherein a first width of the front waist region, taken in a direction parallel to a central lateral axis of the absorbent article, is wider than a second width of the crotch region, taken in a direction parallel to the central lateral axis of the absorbent article.

10. The absorbent article of claim 1 , comprising front ear panels in the front waist region.

11. The absorbent article of claim 1 , comprising rear ear panels in the rear waist region and comprising a landing zone in the front waist region.

12. The absorbent article of claim 1 , comprising an elastic waist feature in the rear waist region.

13. The absorbent article of claim 1 , comprising elasticized leg cuffs.

14. The absorbent article of claim 1 , comprising a core wrap surrounding the absorbent particulate polymer material and wood pulp, wherein the core wrap comprises a first nonwoven layer and a second nonwoven layer.

15. The absorbent article of claim 1 , wherein the absorbent article is a taped diaper.

16. The absorbent article of claim 1 , wherein the basis weight of the absorbent particulate polymer material in the absorbent core varies in regions about the cavity.

17. An absorbent article, comprising:

a front waist region;

a back waist region;

a crotch region positioned between the front waist region and the back waist region;

a topsheet;

a backsheet;

an absorbent core disposed between the topsheet and the backsheet, the absorbent core comprising absorbent particulate polymer material and wood pulp; and

wherein a cavity is defined in the absorbent core;

wherein at least a portion of the absorbent particulate polymer material in the absorbent core is in the cavity;

wherein the portion of the absorbent particulate polymer material in the cavity has a lower basis weight than other absorbent particulate polymer material in the absorbent core and not in the cavity;

wherein the cavity comprises a first channel extending in a first direction;

wherein the cavity comprises a second channel extending in a second, different direction; and

wherein the cavity is discrete and is defined in and bounded by absorbent zones.

18. The absorbent article of claim 17 , wherein the first channel has substantially the same length as the second channel, and wherein at least a portion of the first channel has substantially the same width as at least a portion of the second channel.

19. The absorbent article of claim 17 , wherein a first width of the front waist region, taken in a direction parallel to a central lateral axis of the absorbent article, is wider than a second width of the crotch region, taken in a direction parallel to the central lateral axis of the absorbent article.

20. The absorbent article of claim 17 , comprising:

front ear panels in the front waist region;

rear ear panels in the rear waist region;

a landing zone in the front waist region;

an elastic waist feature in the rear waist region; and

elasticized leg cuffs;

wherein the absorbent article is a taped diaper.
