Absorbent article
First Claim
1. A disposable absorbent article comprising:
- a liquid pervious topsheet;
a liquid impervious backsheet joined with said topsheet; and
an absorbent element disposed between said topsheet and said backsheet;
wherein said backsheet comprises a flexure-resistant deformation element, said deformation element having a flexure means for inducing bending of said deformation element in a preconceived way into a preconceived convex upward geometric configuration when the absorbent article is subjected to lateral compressive forces.

Abstract
The present invention is directed to a disposable absorbent article, and particularly a sanitary napkin, having a flexure-resistant deformation element, the sanitary napkin having a body surface which has a convex upward configuration when the sanitary napkin is worn. Primarily without relying on lateral compressive forces of the wearer'"'"'s labia, the sanitary napkin of the present invention relies on the lateral compressive forces of the wearer'"'"'s thighs in order to form or maintain a convex upward configuration when the sanitary napkin is worn. In a preferred embodiment, the deformation element has a means for inducing the body surface of the sanitary napkin to have a convex upward configuration when the sanitary napkin is worn. In an alternatively preferred embodiment, the sanitary napkin has a central region having a "W" shaped cross-section wherein the body surface of the sanitary napkin having the convex upward configuration is located in the central region, generally symmetrically between the longitudinal side edges of the sanitary napkin. In another alternatively preferred embodiment, the sanitary napkin has a cup-shaped front region and a back region having a convex upward configured body surface. The deformation element may be a moldable substance such as a foam, it may be reformable and/or it may be resilient.
