Absorbent article with high stiffness
First Claim
1. Absorbent article which article has a generally elongated shape with a longitudinal direction and a transverse direction and exhibits two side edges, two end edges, two end portions and a crotch portion located between the end portions, which article furthermore exhibits a liquid-pervious cover layer, intended to be facing the user when worn, and a liquid-impervious cover layer, intended to be facing away from the user when worn, wherein the article at least within the crotch portion comprises a stiffening element of a material with a very high intrinsic stiffness so as to maintain substantial shape permanence of the article while worn by a user, whereby within at least a 5 mm extension of the crotch portion in the longitudinal direction, the article has an extension in the transverse direction which is between 15 mm and 40 mm while the article is worn by a user.

Abstract
The invention relates to an absorbent article such as a sanitary napkin, an incontinence guard, or a panty-liner, which article has a generally elongated shape with a longitudinal direction and a transverse direction and exhibits two side edges (9, 10), two end portions (6, 7), and a crotch portion (8) located between the end portions (6, 7), which article further exhibits a liquid-pervious cover layer (2), intended to be facing the user during use, and a liquid-impervious cover layer (3), intended to be facing away from the user during use. The article comprises at least within the crotch portion (8) a stiffening element (15) of a material with a very high intrinsic stiffness, whereby the article in the crotch portion (8) has an extension in the transverse direction which during use of the article is between 40 mm and 15 mm and preferably is between 20 mm and 35 mm.
