Abstract

A disposable absorbent article with a water-permeable covering sheet, a water-impermeable center sheet, and an absorbent core disposed therebetween is disclosed herein. The absorbent article includes a pair of side flaps comprising a first side flap and an opposing second side flap; each of the first and second side flaps being made from a distinct layer of material that is not an extension of the water-permeable covering sheet or the water-impermeable center sheet. The distinct layer of material is doubled over to form a first layer comprising a first layer proximal edge, and a second layer comprising a second layer proximal edge, wherein the first layer and the second layer enclose an elastic strand, and wherein the first layer is attached to the second layer.

First claim

What is claimed is:

1. A disposable absorbent article, comprising:
a wearer-facing surface;
an opposing garment-facing surface;
an absorbent core disposed between the wearer-facing surface and the garment-facing surface;
a first side edge and an opposing second side edge;
a first side flap and an opposing second side flap, each of the first and second side flaps forming at least a portion of the wearer-facing surface, each of the first and second side flaps each comprising a first layer and a second layer, the first layer comprising a first layer proximal edge and the second layer comprising a second layer proximal edge;
wherein the first layer and the second layer enclose an elastic strand;
wherein the first layer is attached to the second layer;
wherein the first layer proximal edge of the first side flap is disposed laterally inward from the first side edge of the absorbent article and is attached to the garment-facing surface of the absorbent article, wherein second layer proximal edge of the first side flap is attached to the first layer of the first side flap and is disposed laterally inward from the first side edge of the absorbent article and is attached to the garment-facing surface of the absorbent article, and wherein the first layer proximal edge of the first side flap extends more laterally inboard than the second layer proximal edge of the first side flap; and
wherein the first layer proximal edge of the second side flap is disposed laterally inward from the second side edge of the absorbent article and is attached to the garment-facing surface of the absorbent article, and wherein the second layer proximal edge of the second flap is attached to the first layer of the second side flap and is disposed laterally inward from the second side edge of the absorbent article and is attached to the garment-facing surface of the absorbent article, and wherein the first layer proximal edge of the second side flap extends more laterally inboard than the second layer proximal edge of the second side flap.

2. The disposable absorbent article of claim 1 , wherein the absorbent core is asymmetric about a lateral axis of the article.

3. The disposable absorbent article of claim 1 , wherein the absorbent core comprises an acquisition component overlying a storage component.

4. The disposable absorbent article of claim 1 , wherein the absorbent core comprises wood pulp and superabsorbent polymer.

5. The disposable absorbent article of claim 1 , wherein the side flaps are water vapor permeable.

6. The disposable absorbent article of claim 1 , wherein the side flaps comprise a nonwoven.

7. The disposable absorbent article of claim 1 , wherein the side flaps comprise a spunbond meltblown nonwoven.

8. The disposable absorbent article of claim 1 , wherein the article has a chassis that is hourglass-shaped.

9. The disposable absorbent article of claim 1 , wherein the garment-facing surface comprises a film.

10. The disposable absorbent article of claim 1 , wherein the article is an incontinence article.

11. The disposable absorbent article of claim 10 , wherein the incontinence article is a diaper.

12. The disposable absorbent article of claim 1 , wherein each of the pair of side flaps comprise a side flap proximal edge and an elastic strand disposed adjacent to the side flap proximal edge.

13. The disposable absorbent article of claim 12 , wherein the elastic strand does not extend a full length of the first side flap or the second side flap.

14. The disposable absorbent article of claim 12 , wherein the first layer and the second layer are attached to one another at an attachment zone, and wherein the elastic strand is disposed nearer to the side flap proximal edge than the attachment zone.

15. The disposable absorbent article of claim 1 , wherein the absorbent core further comprises an acquisition component, a storage component, and a separation sheet disposed between the acquisition component and the storage component.

16. The disposable absorbent article of claim 15 , wherein the separation sheet is a nonwoven material.

17. The disposable absorbent article of claim 15 , wherein the absorbent core further comprises a lower covering sheet.

18. The disposable absorbent article of claim 1 , wherein the side flaps comprise a discrete material.

19. The disposable absorbent article of claim 1 , wherein the first side flap and the second side flap comprise a crease in a crotch region of the disposable absorbent article.
