CA 2205898

Absorbent articles, such as disposable diapers, having two waist regions and a crotch region are provided. The absorbent articles comprise a liquid pervious topsheet, a liquid impervious backsheet, an absorbent core disposed between the topsheet and the backsheet, and a pair of longitudinally extending barrier cuffs. The barrier cuffs are formed from a lateral extension of the topsheet and the backsheet in at least the crotch region of the absorbent article using material that is normally discarded when the crotch area is formed. A cuff area is defined by pairs of laterally opposed cuts in the lateral extension of the topsheet and the backsheet. The cuff area is then folded and joined to the topsheet or other underlying structure to form the barrier cuff and an optional gasketing cuff.

L'invention concerne des articles absorbants, tels que des couches jetables, possédant deux zones de taille et une zone d'entrejambe. Ces articles absorbants comprennent une couche supérieure perméable aux liquides, une couche inférieure imperméable aux liquides, une couche centrale absorbante située entre la couche supérieure et la couche inférieure et une paire de bandes anti-fuite s'étendant dans le sens de la longueur. Celles-ci sont constituées à partir d'un prolongement latéral de la couche supérieure et de la couche inférieure au moins dans la zone de l'entrejambe de l'article absorbant au moyen d'un matériau qui est normalement jeté lorsque ladite zone est formée. Une zone périphérique est définie par des paires d'entailles opposées latéralement dans le prolongement latéral de la couche supérieure et de la couche inférieure. Cette zone est ensuite repliée et réunie à la couche supérieure ou à une autre structure sous-jacente, afin de constituer la zone anti-fuite, ainsi qu'une zone d'étanchéité éventuelle.
