  • Publication number: 20030199842
    Abstract: The present invention relates to an absorbent article for managing bodily fluids, comprising a high coefficient of friction (“COF”) backsheet and at least one tape tab extending therefrom. The tape tab comprises a minimum amount of pressure sensitive adhesive sufficient to maintain the position of the article when a user's undergarments are away from her body. When the undergarments are near her body, the high COF backsheet acts as the predominant means for maintaining the position of the article due to normal forces exerted by the user's body and undergarments. When the user wants to remove the article from her undergarments, the tape tab provides additional advantages. The user may grasp the tape tab itself for removing the article as an alternative to grasping a portion of the soiled article. In addition the soiled article may be folded or rolled up, and then held in that configuration with the tape tab, for convenient and discreet disposal.

  • Patent number: 6632210
    Abstract: A sanitary napkin has a strip that extends rearwardly to reside in the intergluteal crevice. The pad fits snugly against the body without penetrating. Because the strip provides improved body contact, similar protection is achieved with a smaller pad, thus providing a discretion benefit to the wearer.

  • Patent number: 6530910
    Abstract: The present invention is directed to a flushable release liner/wiper combination. The flushable release liner/wiper combination is formed by applying a release coating onto a first surface of a water-sensitive film and an absorbent fibrous material onto an opposite surface of the water-sensitive film. The flushable release liner/wiper combination maintains its integrity and strength when in use, but loses its integrity and strength when placed in contact with water. The flushable release liner/wiper combination quickly breaks up and disperses in a flushing toilet or sink due to the force of the flowing water on the liner/wiper combination. Moreover, the present invention is directed to methods of making the flushable release liner/wiper combination and water-dispersible products, including flushable products, which contain the flushable release liner/wiper combination.

  • Patent number: 6254582
    Abstract: A supply of absorbent panty liner pads formed by a contiguous longitudinal array of pad segments forming a strip. The strip has locally weakened zones to facilitate tearing off segments from the strip without the use of a cutting tool. Each pad segment is shorter than a standard panty liner pad so that approximately three segments are required to form a standard length pad. By tearing off two, three, four, or five segments in one piece, the user can create a panty liner having a short, standard, long or extra long length to suit her needs on any given day. The strip is wrapped upon itself into a roll so that pressure sensitive positioning adhesive strips are placed into contact with release surfaces formed on the strip, thereby protecting the adhesive prior to use without the need for release paper.
