Absorbent article capable of self-shaping in use

摘要

A disposable absorbent article which is substantially flat prior to use for wearing adjacent a body discharge area having a longitudinal centreline and a lateral centreline orthogonal thereto and defining longitudinal and lateral directions respectively. The disposable absorbent article comprises a liquid pervious topsheet, a backsheet joined to said topsheet and an absorbent core intermediate the backsheet and the topsheet. The absorbent core comprises an expanding layer for expanding the article into a tridimensional structure while being worn by a user. The expanding layer is activated by body fluids and has a constant thickness in the dry state prior to use. The expanding layer is capable, upon full activation by body fluids, of expanding into a predetermined profile of non-constant thickness.
