Abstract
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.
