Abstract
Abstract The present invention relates to a disposable absorbent article (1) such as a diaper or an incontinence protector intended during use to seal like a pant around the user's abdomen and comprising an absorption body (4) applied between a liquid impermeable outer layer (2) facing away from the user and a liquid permeable inner layer (3) facing the user, these two layers being interconnected at least along the long sides of the article. The inventive article is primarily distinguished in that a strip (13,14) of a liquid impermeable material, extending in the transverse direction of the article, is disposed at least at one end portion of the article, this strip having a portion (16,17) positioned between the absorption body (4) and the liquid permeable inner layer (3) and a portion (18,19) folded over the end edge (10,15) of the absorption body while being secured to the liquid impermeable outer layer (2), the article thereby obtaining a liquid-tight reinforced edge portion (22,23).
