  • Patent number: 6152905
    Abstract: The present invention provides an absorbent device insertable into the interlabial space of a female wearer. The absorbent device comprises a main absorbent portion comprising an upper portion and a lower portion. The upper portion has a top surface facing toward the vestibule floor of the wearer during insertion into the interlabial space. The upper portion leads the lower portion during insertion of the absorbent device; i.e., the lower portion is spatially opposed to the upper portion, and upon insertion of the absorbent device into a wearer's interlabial space, the lower portion faces away from the vestibule floor of the wearer. Additionally, a fluid acquisition/transfer complex is positioned about and extends at least from the upper portion of the main absorbent portion. The fluid acquisition/transfer complex is configured to be in intimate contact with the folds and creases of the interlabial space of the female wearer.

  • Patent number: 5324278
    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.
