Abstract

A disposable absorbent article includes a chassis and an absorbent assembly and is adapted to be configured as a loincloth diaper for use in combination with a support element that is worn around the waist of the wearer. The chassis has fastening elements for use in forming laterally extending tunnels adjacent to the waist edges through which the support element extends. The chassis includes a water-impermeable backsheet that may be folded laterally inward at both of its side edges to form opposing side flaps. Each side flap is attached to the interior surface of the chassis adjacent to its end edges. Each side flap has a longitudinally extending elastic gathering member attached adjacent to its proximal edge. The chassis may include an extensible formed web material. The absorbent assembly may be attached in a cruciform pattern to the chassis to allow unattached portions of the chassis to extend laterally.

Claims

1. A disposable loincloth diaper comprising:

an absorbent assembly comprising an absorbent core; and

a chassis having a longitudinal axis, a lateral axis, a front waist region having a front waist edge, a back waist region having a back waist edge, a crotch region between the waist regions, laterally opposing side edges extending between the front waist edge and the back waist edge, an exterior surface, and an interior surface to which the absorbent assembly is attached,

the chassis comprising a water-impermeable backsheet and laterally opposing side flaps attached to the interior surface adjacent to their longitudinally distal ends, each of the side flaps having a longitudinally extending elastic gathering member attached adjacent to its proximal edge,

the chassis further comprising fastening elements disposed on the exterior surface adjacent to the waist edges, the fastening elements being adapted to maintain each of the waist edges in a folded-over configuration forming a laterally extending tunnel such that a portion of the exterior surface is disposed inside the tunnel, the tunnel being adapted to have a support element worn around a waist of a wearer extending through it and used to support the waist regions adjacent to the waist of the wearer and thereby position the absorbent assembly to receive and contain urinary and fecal waste excreted by the wearer.

2. The disposable loincloth diaper of claim 1 further comprising the support element.

3. The disposable loincloth diaper of claim 2 pre-assembled with the support element extending through the tunnel.

4. The disposable loincloth diaper of claim 2 wherein the support element includes an elastic material.

5. The disposable loincloth diaper of claim 2 wherein the support element has the form of a closed loop.

6. The disposable loincloth diaper of claim 1 wherein at least one of the fastening elements is laterally continuous.

7. The disposable loincloth diaper of claim 1 wherein at least one of the fastening elements is laterally discretely segmented.

8. The disposable loincloth diaper of claim 1 wherein at least one of the fastening elements is openable and refastenable.

9. The disposable loincloth diaper of claim 1 wherein at least one of the fastening elements includes an adhesive material.

10. The disposable loincloth diaper of claim 1 wherein at least one of the fastening elements includes a cohesive material.

11. The disposable loincloth diaper of claim 1 wherein at least one of the fastening elements includes a mechanical fastener.

12. The disposable loincloth diaper of claim 1 wherein the absorbent assembly is attached to the chassis in a cruciform attachment pattern.

13. The disposable loincloth diaper of claim 12 wherein at least a portion of the chassis lying outside the cruciform pattern is laterally extensible.

14. The disposable loincloth diaper of claim 1 wherein the backsheet is a laminate of a film and a nonwoven material disposed exteriorly of the film.

15. The disposable loincloth diaper of claim 14 wherein at least one of the fastening elements includes hooks adapted to engage with the nonwoven material of the backsheet.

16. A disposable loincloth diaper comprising:

an absorbent assembly comprising an absorbent core; and

a chassis having a longitudinal axis, a lateral axis, a front waist region having a front waist edge, a back waist region having a back waist edge, a crotch region between the waist regions, laterally opposing side edges extending between the front waist edge and the back waist edge, an exterior surface, and an interior surface to which the absorbent assembly is attached,

the chassis comprising a water-impermeable backsheet and laterally opposing side flaps attached to the interior surface adjacent to their longitudinally distal ends, each of the side flaps having a longitudinally extending elastic gathering member attached adjacent to its proximal edge,

the chassis further comprising fastening elements disposed on the interior surface adjacent to the waist edges, the fastening elements being adapted to maintain each of the waist edges in a folded-over configuration forming a laterally extending tunnel such that a portion of the interior surface is disposed inside the tunnel, the tunnel being adapted to have a support element worn around a waist of a wearer extending through it and used to support the waist regions adjacent to the waist of the wearer and thereby position the absorbent assembly to receive and contain urinary and fecal waste excreted by the wearer.

17. The disposable loincloth diaper of claim 16 wherein the chassis further comprises an inner liner formed of a nonwoven material and at least one of the fastening elements includes hooks adapted to engage with the nonwoven material of the inner liner.

18. A disposable loincloth diaper comprising:

an absorbent assembly comprising an absorbent core; and

a chassis having a longitudinal axis, a lateral axis, a front waist region having a front waist edge, a back waist region having a back waist edge, a crotch region between the waist regions, laterally opposing side edges extending between the front waist edge and the back waist edge, an exterior surface, and an interior surface to which the absorbent assembly is attached,

the chassis comprising a water-impermeable backsheet and laterally opposing side flaps attached to the interior surface adjacent to their longitudinally distal ends, each of the side flaps having a longitudinally extending elastic gathering member attached adjacent to its proximal edge,

the chassis further comprising fastening elements disposed adjacent to the waist edges, the fastening elements being adapted to maintain each of the waist edges in a folded-over configuration forming a laterally extending tunnel adapted to have a support element worn around a waist of a wearer extending through it and used to support the waist regions adjacent to the waist of the wearer and thereby position the absorbent assembly to receive and contain urinary and fecal waste excreted by the wearer.

19. The disposable loincloth diaper of claim 18 wherein the fastening elements are disposed on the exterior surface adjacent to the waist edge in one of the waist regions and on the interior surface adjacent to the waist edge in the opposing waist region, such that a portion of the exterior surface is disposed inside the tunnel in the one of the waist regions and a portion of the interior surface is disposed inside the tunnel in the opposing waist region.

20. The disposable loincloth diaper of claim 18 wherein at least one of the fastening elements is laterally discretely segmented.
