CA 2093350

A disposable absorbent article, such as a sanitary napkin, is disclosed that has components which may separate in the Z-direction with relation to other components of the article when the absorbent article is worn. The sanitary napkin of the present invention comprises a liquid pervious topsheet, a liquid impervious backsheet, an absorbent core positioned between the topsheet and the backsheet, and a liquid pervious spacing structure for moving the topsheet away from the core. The spacing structure is generally positioned between the topsheet and the core. The spacing structure has a longitudinal centerline, and opposed lateral sides which may move inwardly toward the longitudinal centerline when the spacing is compressed from the sides. This results in at least a portion of the spacing structure moving the topsheet apart from the absorbent core. In an alternative embodiment, the sanitary napkin of the present invention also has an absorbent core which separates from the backsheet of the sanitary napkin.

Article absorbant jetable, par exemple une serviette hygiénique, comportant des éléments pouvant se séparer dans la direction Z par rapport aux autres composants de l'article, lorsque ledit article absorbant est porté. La serviette hygiénique faisant l'objet de la présence invention comporte une couche supérieure perméable, une couche inférieure imperméable, une couche centrale absorbante placée entre les couches supérieure et inférieure, et une structure d'espacement perméable séparant la couche supérieure de la couche centrale. La structure d'espacement est essentiellement placée entre la couche supérieure et la couche centrale. Ladite structure est dotée d'une ligne centrale longitudinale et de côtés qui peuvent se déplacer vers l'intérieur en direction de la ligne centrale longitudinale lorsque l'espacement est réduit à partir des côtés. Cela a pour effet qu'au moins une partie de la structure d'espacement éloigne la couche supérieure de la couche absorbante. Dans une autre application, la serviette hygiénique faisant l'objet de la présente invention est également munie d'une couche centrale absorbante qui est séparée de la couche inférieure.
