An absorbent article having two side edges (9, 10) and two end edges (11, 12), and comprising a liquid-permeable cover layer (2), a liquid-impermeable cover layer (3), and an absorption body (4) enclosed between the two cover layers (2, 3). The article further comprises a barrier layer (15) arranged outside the liquid-permeable cover layer (2). At least one elastic member (22, 23) is arranged with prestressing in direct contact with the absorption body (4) and extends in an arched curve across the absorption body (4) between the side edges (9, 10). The barrier layer (15) partly covers the liquid-permeable cover layer and is anchored in the liquid-permeable cover layer (2) only within areas of the barrier layer (15) which are situated along the edges (9-12) of the article. At least one elastic member (21) is arranged in direct connection with the barrier layer (15), as a result of which the elastic member (21) cooperates with the elastic member (22, 23) arranged in contact with the absorption body (4) so as to form a constantly basin-shaped space (26) between the barrier layer (15) and the liquid-permeable cover layer (2).

L'invention concerne un article absorbant possédant deux bords latéraux (9,10) et deux bords terminaux (11, 12) et comprenant une couche de revêtement perméable au liquide (2), une couche de revêtement imperméable au liquide (3), et un corps d'absorption (4) enfermé entre ces deux couches de revêtement (2, 3). Cet article comprend également une couche barrière (15) placée à l'extérieur de la couche de revêtement perméable au liquide (2). Au moins un élément élastique (22, 23) en précontrainte est en contact direct avec le corps d'absorption (4) entre les bords latéraux (9, 10). La couche barrière (15) recouvre partiellement la couche de revêtement perméable au liquide dans laquelle elle est ancrée seulement au niveau de parties de la couche barrière (15) situées le long des bords (9 à 12) de l'article. Au moins un élément élastique (21) est placé en liaison directe avec la couche barrière (15). Ainsi, l'élément élastique (21) coopère avec l'élément élastique (22, 23) en contact avec le corps d'absorption (4) de façon à former un espace (26) ayant constamment une forme de bassin entre la couche barrière (15) et la couche de revêtement perméable au liquide (2).
