Layer Coated Or Treated To Decrease Absorbency Patents (Class 604/381)
  • Patent number: 7312372
    Abstract: Disclosed is an elongated absorbent article including a liquid absorbent layer. In a region where the liquid absorbent layer is present, compressed grooves are disposed to extend symmetrically about a longitudinal centerline, defining a central region therebetween and side regions laterally outside the central region and adjacent the compressed grooves. The central region includes front, intermediate and rear central regions. The intermediate central region has a widened portion in which the separation distance is larger than in regions positioned forward and rearward thereof. Stiffness of the side regions is lower in portions laterally outside the intermediate central region than in portions laterally outside the front and rear central regions.

  • Patent number: 6897351
    Abstract: In a disposable diaper in which an absorbent body is provided between a water-repellent outer sheet and a hydrophilic skin-side sheet made of a nonwoven fabric, raisable strips made of a nonwoven fabric are provided at the opposite sides of the skin-side sheet, elastic threads for raisable gathers are provided in inner edge portions of the raisable strips and the outer edge portions of the raisable strips are adhered to the skin-side sheet, an ooze preventing portion for preventing an ooze of urine and other bodily waste is formed at opposite end portions of the skin-side sheet. Therefore, even if urine and other bodily waste permeate into the skin-side sheet, they do not ooze out from the end portion of the skin-side sheet.

  • Patent number: 6670523
    Abstract: Disclosed is a tampon that is impregnated with a means which is water-repellent as well as infection inhibitory. Said tampon is thus particularly useful for swimming and bathing. Washing-out of the infection inhibitory component is prevented by using an impregnation means combined of a half-solid or solid support with an infection inhibitory means based on plant oils which act accordingly. The inventive tampon is thus useful for long-term application in water.

    Abstract: A disposable absorbent article, e.g., a diaper, having a top sheet, a back sheet, a core and a fluid acquisition system. The fluid acquisition system is formed by wrapping a layer of a non-woven material about the core, so that the marginal edge portions of the layer overlap each other over the upper surface of the core. The overlapping marginal edge portions are hydrophillic to form a dual layer fluid acquisition system. The remainder of the layer of non-woven material is hydrophobic. An additional layer can be located adjacent the overlapping portions to form a three layer acquisition system.

    Abstract: An absorbent swimwear garment having a fluid draining mechanism included in the layers of the garment. The swimwear garment includes a body side liner, an outer cover, and an absorbent assembly between the body side liner and the outer cover. Between the absorbent assembly and the outer cover is a layer of water-dispersible material, such as a film or a nonwoven web, coated on a surface facing the absorbent assembly with a barrier coating. During initial product use, the absorbent swimwear garment is able to contain urine and bowel movements, similar to ordinary diapers and training pants. When the swimwear garment is submersed in swim water, such as pool or lake water, the water-dispersible material becomes soluble and allows swim water, but not bowel movements, to drain out through the outer cover of the garment.

    Abstract: The present invention provides a material for distributing liquid and a method for making such a material. The material includes a substrate permeable to a liquid and a chemical treatment applied to at least a portion of the substrate. The substrate further includes a leakage prevention means of at least one area of an increased concentration of the chemical treatment such that the chemical treatment is non-uniform along a planar dimension of the substrate and creates an area of preferential flow through the substrate. The chemical treatment useful for application to the substrate preferably induces wetting of the substrate by a liquid. The material for distributing liquid has best utility as a component of an absorbent article, e.g. a liner of a diaper. In a preferred embodiment, the substrate is attached to an absorbent layer such that the absorbent layer receives and retains the liquid when the liquid flows from a first planar dimension to a second planar dimension.

  • Publication number: 20010000795
    Abstract: The present invention provides a material for distributing liquid and a method for making such a material. The material includes a substrate permeable to a liquid and a chemical treatment applied to at least a portion of the substrate. The substrate further includes a leakage prevention means of at least one area of an increased concentration of the chemical treatment such that the chemical treatment is non-uniform along a planar dimension of the substrate and creates an area of preferential flow through the substrate. The chemical treatment useful for application to the substrate preferably induces wetting of the substrate by a liquid. The material for distributing liquid has best utility as a component of an absorbent article, e.g. a liner of a diaper. In a preferred embodiment, the substrate is attached to an absorbent layer such that the absorbent layer receives and retains the liquid when the liquid flows from a first planar dimension to a second planar dimension.

  • Patent number: 6133501
    Abstract: An absorbent article includes an outer cover, a bodyside liner and an absorbent core. A fecal retaining structure defines a perimeter having an aperture therein. The fecal retaining structure includes channels extending outwardly from the aperture. The fecal retaining structure preferably includes a cavity about the perimeter thereof and in communication with the channels. The cavity preferably communicates with the channels and provides additional volume for storage of fecal material. The fecal retaining structure preferably is formed by two layers of resiliently compressible material having different rigidity and compression resistance. One of the layers is smaller than the other layer such that space to form the cavity is present inside the fecal retaining structure. In a preferred embodiment the fecal retaining structure has a bicycle-seat shape with the narrow front portion extending into the front portion of the absorbent article.

  • Patent number: 6025535
    Abstract: The present invention provides a fluid previous fibrous, preferably nonwoven, web having a first surface and a second surface. The web comprises a hydrophilic nonwoven web comprising a plurality of individual, preferably whitened, brightened, and/or opacified, fibers associated with one another. The web includes a plurality of surface energy gradients defined by the boundaries of discontinuous, spaced regions of the web which are located on the first surface which exhibit a different surface energy than an adjacent portion of the web. The regions comprise depositions of a preferably whitened, brightened, and/or opacified low surface energy material randomly distributed over the first surface. In a preferred embodiment, the nonwoven web is formed of shaped fibers of substantially non-circular cross-section, preferably a trilobial or delta cross-section, which include whitening, brightening, and opacifying agents within the fiber material.

  • Patent number: 5990377
    Abstract: A dual-zoned, three-dimensional, resilient absorbent web is disclosed which is suitable as body-side liner for absorbent articles such as feminine pads, diapers and the like. When used as a liner in absorbent articles, the dual-zoned web combines the advantages of apertured films and soft, nonwoven cover layers in one structure while still being inherently hydrophilic. The liner comprises a web of wet-resilient, hydrophilic basesheet having a three-dimensional topography comprising elevated regions onto which hydrophobic matter is deposited or printed and a plurality of spaced apart depressed regions. In a preferred embodiment, the hydrophobic matter applied to the elevated regions of the basesheet comprises hydrophobic fibers in a contiguous nonwoven web which has been apertured or provided with slits or other openings, such that the apertures or openings overlay a portion of the depressed regions.
