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 having a topsheet, a backsheet and an absorbent core. The article also includes a waist feature having a portion extending longitudinally outboard of the chassis in the waist region. The backsheet includes a barrier layer having a maximum length, L BS . The absorbent core has absorbent material and a maximum length, L CW . 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 , and L AB is about 90% or greater of L BS . The first absorbent area lateral edge is disposed a longitudinal distance, D1, from the first barrier lateral edge, and D1 is about 5% or less of L BS .

Claims (43)

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 at least one of the first waist region and the second waist region, wherein the waist feature comprises a free portion extending longitudinally outboard of the chassis and transversely outboard of the chassis in at least one of the first waist region and the second waist region such that the free portion does not overlap the chassis;

wherein the backsheet comprises an outer cover and a barrier layer,

wherein the barrier layer has a maximum length, L BS , extending between a first barrier lateral edge and a second barrier lateral edge,

wherein 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 ,

wherein the absorbent core comprises a pair of permanent channels substantially free of the absorbent material, and

wherein the outer cover forms an outer wrap configured to wrap the first waist region, the crotch region, and the second waist region.

2. The absorbent article of claim 1 , comprising elastic members disposed on the outer wrap.

3. The absorbent article of claim 1 , wherein the chassis comprises a first barrier leg cuff extending at least partially between a first lateral chassis edge and a second lateral chassis edge, on opposite sides of the longitudinal centerline and being at least present in the crotch region.

4. The absorbent article of claim 3 , wherein the chassis comprises a second of barrier leg cuff extending at least partially between the first lateral chassis edge and the second lateral chassis edge, and wherein the first barrier leg cuff and the second barrier leg cuff extend on opposite sides of the longitudinal centerline.

5. The absorbent article of claim 4 , wherein each of the first and second barrier leg cuffs comprise proximal edges directly joined to the backsheet.

6. The absorbent article of claim 1 , wherein the waist feature comprises a nonwoven web of fibers, wherein the fibers are at least one of spunbond, spunlaid, meltblown, spunmelt, solvent-spun, electrospun, carded, film fibrillated, melt-film, fibrillated, air-laid, dry-laid and wet-laid staple fibers.

7. The absorbent article of claim 6 , wherein the fibers comprise bi-component fibers.

8. The absorbent article of claim 1 , comprising a refastenable side seams.

9. The absorbent article of claim 1 , comprising an absorbent material deposition area comprising the absorbent material, wherein 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 .

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

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

12. The absorbent article of claim 1 , comprising a fastening system.

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

14. 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.

15. An absorbent article comprising:

17. The absorbent article of claim 15 , 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.

18. 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 at least one of the first waist region and the second waist region, wherein the waist feature comprising a free portion extending longitudinally outboard of the chassis in at least one of the first waist region and the 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;

wherein the absorbent core comprises absorbent material enclosed in a core wrap, the core wrap having a maximum length, L CW ,
