  • Patent number: 6478763
    Abstract: An individual package in combination with a hygienic device has a body comprising walls which surround and contain the device within the body; a rupturable seal line running along the axis of at least one side of the body, and an opening member situated on the seal line and extending outward from the body. The hygienic device is positioned within the package. The hygienic device is readily retrievable from the package such that a user neither touches nor contaminates the absorbent portion of the hygienic device with any part of her hand prior to the use and in using the hygienic device. Tampons, interlabial devices, swabs, and bandages are thereby afforded means for sterile usage and subsequent hygienic disposal.

  • Patent number: 6458110
    Abstract: An absorbent article having an expandable component. The expandable component comprises a compressed, resilient element disposed within an air impermeable envelope. The compressed element provides the absorbent article with a thin, low bulk profile prior to use of the disposable absorbent article, thereby reducing shipping and storage space. The user may open the impervious envelope, thereby permitting entry of air into the envelope and expansion of the compressed element. In one embodiment the expandable component is a spacer for maintaining fecal void space in a disposable diaper. Alternatively, the expandable component can provide displacement of the topsheet relative to the backsheet along the longitudinal centerline of a sanitary napkin.

The body-conforming component, in one embodiment, is in the form of a resilient insert which has multiple arcuate portions in use. The insert has a central arcuate portion that provides the sanitary napkin with a convex upward shape in use and a pair of lateral arcuate portions that form barriers to the flow of liquid exudates. The multiple arcuate portions can either be pre-formed into the insert, or the insert can be provided in the form of a relatively flat piece that is provided with areas of different stiffness that form arcuate portions during use.

  • Patent number: 5520674
    Abstract: An absorbent article having an expandable component. The expandable component comprises a compressed, resilient element disposed within an air impermeable envelope. The compressed element provides the absorbent article with a thin, low bulk profile prior to use of the disposable absorbent article, thereby reducing shipping and storage space. At the point of use of the absorbent article, the air impervious envelope is opened, thereby permitting entry of air into the envelope and expansion of the compressed element. In one embodiment the expandable component is a spacer for maintaining fecal void space in a disposable diaper. Alternatively, the expandable component can provide displacement of the topsheet relative to the backsheet along the longitudinal centerline of a sanitary napkin.

  • 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.
