Abstract

La présente invention concerne une couche jetable qui comprend un corps principal en forme de feuille, portée de telle manière qu'un membre d'allongement élastique entoure complètement la périphérie de chaque cuisse du corps humain et que les deux extrémités du membre d'allongement élastique sont fixées. La couche jetable permet ainsi d'éviter les fuites latérales. Ladite couche jetable comprend un corps principal en forme de feuille (12) qui est composé d'une partie postérieure (12a), d'une partie antérieure (12b), et d'une partie centrale de raccordement (12c) les reliant, avec un côté interne (12d) et un côté externe. La partie centrale de raccordement (12c) présente un premier membre d'extension élastique librement extensible (40) à proximité de chaque bord (13). Une partie du côté interne (12d) est reliée à une partie du côté externe de telle sorte qu'une extrémité du premier membre d'extension élastique (40) est reliée à l'autre ou rapprochée de l'autre. Ces parties ainsi reliées ou rapprochées l'une de l'autre sont fixées de manière amovible avec un moyen de fixation (50) pour le raccordement.
