  • Patent number: 6840927
    Abstract: An improved absorbent catamenial tampon having increased leakage protection and ability to readily absorb fluid while not aggressively adhering to tissue. This is accomplished with a tampon comprising a compressed absorbent member comprising an absorbent material. The compressed absorbent member of the tampon has an inner region and an exterior surface. The fluid wicking overwrap substantially covers the exterior surface of the compressed absorbent member, substantially permeates the inner region of the compressed absorbent member and extends beyond the withdrawal end to form a skirt portion. A method of making a tampon of the present invention is also disclosed.
    Type: Grant

  • Patent number: H1670
    Abstract: An absorbent article having improved strikethrough, rewet characteristics, and feel is disclosed. The absorbent article has a topsheet comprising a nonwoven material and apertured thermoplastic film. The apertured thermoplastic film is treated with a surfactant preferably by incorporating the surfactant into the resin used to make the thermoplastic film. The combination of the nonwoven material and the surfactant-treated apertured thermoplastic film permit liquids to rapidly penetrate the topsheet while preventing liquid in the absorbent core of the article from flowing back through the topsheet. The nonwoven material provides the topsheet with improved, less plastic-like feel.
