  • Publication number: 20110162989
    Abstract: The present invention is directed to a method of forming a laminate absorbent structure, and a resulting package containing a single continuous running web of the laminate material. Notably, formation of the material is effected by blending a curtain of adhesive fibers with a curtain of particulate material, and depositing the mixture on a moving substrate, preferably provided in the form of a tissue layer. A second substrate, also preferably comprising a tissue layer, is applied on top of the deposited mixture, and pressure applied to form the laminated structure. Notably, attendant to packaging of the laminated material, adjacent layers of the material tend to nest into one another, to form a sandwich in which the density of the material in the package is more than 1.5 times the density of the material after its removal from the package.

  • Patent number: 6743965
    Abstract: An apertured film cover for an absorbent article is disclosed. The cover has an additive combination comprising a diol and a surfactant applied thereto. The additive combination provides surprisingly improved fluid transfer across the cover. It can also provide a benefit by reducing frictional forces during the manufacture of a tampon.

  • Patent number: 6316019
    Abstract: The present invention relates to a low temperature process for adding pharmaceutically active compounds to substrates. The substrates are preferably those used in the manufacture of disposable absorbent articles, or are the articles themselves. The pharmaceutically active compound is selected from the group consisting of: monoesters of a polyhydric aliphatic alcohol and a fatty acid containing from eight to eighteen carbon atoms and wherein said monoester has at least one hydroxyl group associated with its aliphatic alcohol residue; diesters of a polyhydric aliphatic alcohol and a fatty acid containing from eight to eighteen carbon atoms and wherein said diester has at least one hydroxyl group associated with its aliphatic alcohol residue; and mixtures of said monoesters and diesters.

  • Patent number: 5824352
    Abstract: An apparatus for producing an apertured plastic film having a tricot-like texture. The apparatus includes a film forming member comprising a rotatable hollow drum having a pattern of apertures and a topographical outer surface formed by a cluster of peaks and valleys surrounding each aperture. A plastic film is placed on the apices of the peaks and fluid streams are projected against the film while the drum is rotated. The fluid forces the film against the topographical outer surface of the drum causing the film to become apertured and to have a tricot-like texture corresponding to the pattern of apertures and peaks and valleys.

  • Patent number: 5681301
    Abstract: A disposable absorbent article comprises an absorbent panel and a backing web secured to the panel. A preferred form of the web comprises an apertured film. The web may also include other components on the apertured film, including adhesive. The apertured film is preferably produced from a solid precursor film. The precursor film comprises a copolymer of ethylene and a comonomer polymerized using a single-site metallocene-type polymerization catalyst. The apertured film is formed from the precursor film so that the apertured film has localized deformations and apertures therein. The apertured film exhibits breathability, strength, and flexibility with an elasticity accommodating stretch or elongation and at least partial recovery.
