Abstract

An absorbent article includes a first waist region, a second waist region, and a crotch region disposed between the first and second waist regions; and a chassis comprising a topsheet, a backsheet and an absorbent core. The article also includes a waist feature joined to the chassis a waist region and having a portion extending longitudinally outboard of the chassis in said waist region. The backsheet has a barrier layer having a maximum length, L BS . The absorbent core has absorbent material and a maximum length, L CW , and wherein L CW is substantially the same as L BS . The absorbent material is disposed in an absorbent material deposition area. The absorbent material deposition area has a maximum length, L AB , wherein L AB is about 90% or greater of L BS . The first absorbent area lateral edge is disposed a longitudinal distance, D 1 , from the first barrier lateral edge, wherein D 1 is 5% or less of L BS .

Claims (38)

1. An absorbent article comprising:

a first waist region, a second waist region, and a crotch region disposed between the first and second waist regions; a longitudinal centerline and a lateral centerline;

a chassis comprising a topsheet, a backsheet and an absorbent core disposed between the topsheet and the backsheet; and

a waist feature joined to the chassis in the first and/or second waist region and having a free portion extending longitudinally outboard of the chassis in said first and/or second waist region such that the free portion does not overlap the chassis;

wherein:

the backsheet comprises a barrier layer having a maximum length, L BS , extending between a first barrier lateral edge and a second barrier lateral edge;

the absorbent core comprises absorbent material enclosed in a core wrap, the core wrap having a maximum length, L CW , and wherein L CW is substantially the same as L BS ;

the absorbent material is disposed in an absorbent material deposition area, the absorbent material deposition area having a maximum length, L AB , extending between a first absorbent area lateral edge and a second absorbent area lateral edge, wherein L AB is about 90% or greater of L BS ;

the first absorbent area lateral edge is disposed a longitudinal distance, D 1 , from the first barrier lateral edge, wherein D 1 is 5% or less of L BS ;

wherein the barrier layer is breathable and wherein the waist feature is breathable and comprises a greater breathability than the barrier layer.

2. The absorbent article of claim 1 wherein the second absorbent area lateral edge is disposed a longitudinal distance D 2 from the second barrier lateral edge, wherein D 2 is 5% or less of L BS .

3. The absorbent article of claim 1 wherein the free portion of waist feature extends longitudinally outboard of the chassis by a minimum distance E, and where E is about 15 mm or greater.

4. The absorbent article of claim 1 further comprising a total absorbent capacity at least about 200 g according to the CRC test method herein.

5. The absorbent article of claim 1 wherein the waist feature comprises a pocket formed from a portion of the waist element that is at least partially unattached from the chassis.

6. The absorbent article of claim 1 wherein portions of the waist feature at least partially wrap about the absorbent core.

7. The absorbent article of claim 1 further comprising a fastening system.

8. The absorbent article of claim 1 wherein the absorbent article comprises a pant.

9. The absorbent article of claim 1 comprising a maximum length, L, and wherein the maximum length of the barrier layer, L BS , is less than about 75% of L.

10. The absorbent article of claim 1 comprising a maximum length, L, and wherein L is about 600 mm or less.

11. The absorbent article of claim 1 wherein the waist feature comprises a length, L W , of at least about 25 mm.

12. An absorbent article comprising:

a first waist region, a second waist region, and a crotch region disposed between the first and second waist regions; a longitudinal centerline and a lateral centerline;

a chassis comprising a topsheet, a backsheet and an absorbent core disposed between the topsheet and the backsheet; and

a waist feature joined to the chassis in the first and/or second waist region and having a free portion extending longitudinally outboard of the chassis in said first and/or second waist region such that the free portion does not overlap the chassis;

wherein:

the backsheet comprises a barrier layer having a maximum length, L BS , extending between a first barrier lateral edge and a second barrier lateral edge;

the absorbent core comprises absorbent material enclosed in a core wrap, the core wrap having a maximum length, L CW , and wherein L CW is substantially the same as L BS ;

the absorbent material is disposed in an absorbent material deposition area, the absorbent material deposition area having a maximum length, L AB , extending between a first absorbent area lateral edge and a second absorbent area lateral edge, wherein L AB is about 90% or greater of L BS ;

the first absorbent area lateral edge is disposed a longitudinal distance, D 1 , from the first barrier lateral edge, wherein D 1 is 5% or less of L BS ; and

wherein portions of the waist feature at least partially wrap about the absorbent core.

13. The absorbent article of claim 12 wherein the second absorbent area lateral edge is disposed a longitudinal distance D 2 from the second barrier lateral edge, wherein D 2 is 5% or less of L BS .

14. The absorbent article of claim 12 wherein the free portion of waist feature extends longitudinally outboard of the chassis by a minimum distance E, and where E is about 15 mm or greater.

15. The absorbent article of claim 12 further comprising a total absorbent capacity at least about 200 g according to the CRC test method herein.

16. The absorbent article of claim 12 wherein the waist feature comprises a pocket formed from a portion of the waist element that is at least partially unattached from the chassis.

17. The absorbent article of claim 12 further comprising a fastening system.

18. The absorbent article of claim 12 wherein the absorbent article comprises a pant.

19. The absorbent article of claim 12 comprising a maximum length, L, and wherein the maximum length of the barrier layer, L BS , is less than about 75% of L.

20. The absorbent article of claim 12 comprising a maximum length, L, and wherein L is about 600 mm or less.
