A simple disposable absorbent article including a chassis and an absorbent assembly. The chassis includes a water-impermeable sheet 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 absorbent assembly is smaller in width and in length than the chassis. The side edges and end edges of the absorbent assembly may be disposed proximally relative to the respective side edges and end edges of the chassis. The absorbent assembly includes an absorbent core that may contain superabsorbent particles, which may be contained inside pockets. The chassis may be extensible. The absorbent assembly may be in a cruciform pattern to the chassis to allow portions of the chassis to extend laterally.
1. A disposable absorbent article, comprising: a. a water-permeable covering sheet;b. a water-impermeable center sheet comprising a first side edge, an opposing second side edge, a first side that faces toward the water-permeable covering sheet, and a second side that faces away from the water-perme
1. A disposable absorbent article, comprising: a. a water-permeable covering sheet;b. a water-impermeable center sheet comprising a first side edge, an opposing second side edge, a first side that faces toward the water-permeable covering sheet, and a second side that faces away from the water-permeable covering sheet;c. an absorbent core disposed between a water-permeable covering sheet and a water-impermeable center sheet;d. 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;e. wherein 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;f. wherein the first layer and the second layer enclose an elastic strand;g. wherein the first layer is attached to the second layer;h. wherein the first layer proximal edge of the first side flap is disposed laterally inward from the first side edge of the water-impermeable center sheet and is adjacent to the second side of the water-impermeable center sheet, but is disposed laterally outward from the second layer proximal edge of the first flap that is also adjacent to the second side of the water-impermeable center sheet; andi. wherein the first layer proximal edge of the second side flap is disposed laterally inward from the second side edge of the water-impermeable center sheet and is adjacent to the second side of the water-impermeable center sheet, but is disposed laterally outward from the second layer proximal edge of the second flap that is also adjacent to the second side of the water-impermeable center sheet. 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 water-impermeable center sheet comprises a polyolefin 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 is asymmetric about a lateral axis of the article. 16. 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. 17. The disposable absorbent article of claim 16, wherein the separation sheet is a nonwoven material. 18. The disposable absorbent article of claim 16, wherein the absorbent core further comprises a lower covering sheet.
