  • Publication number: 20020082572
    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.

  • Patent number: 6410821
    Abstract: The present invention provides an absorbent article having a first waist region, an opposed second waist region, a crotch region disposed between the first waist region and the second waist region. The absorbent article preferably comprises a liquid impervious backsheet material, an absorbent core and a directionally preferential waste passage member. The waste passage member has a body facing surface and an opposed garment facing surface, at least a portion of the body facing surface of the waste passage member including a soluble material capable of dissolving when contacted by bodily exudates so as to permit the bodily exudates to pass through the waste passage member in a direction generally away from the wearer's skin. At least a portion of the garment facing surface of the waste passage member includes a barrier material which resists penetration by the bodily exudates in a direction opposite from the first direction.

  • Patent number: 6063067
    Abstract: A disposable diaper has a pair of first surface fastener members supported by a rear flap of a diaper body and a second surface fastener member supported by a front flap of the diaper body. The first and second surface fastener members have first and second engaging elements; the first and/or second engaging elements are made of water-soluble resin. After approximately 1/3 to 2/5 of the diaper body on the side of the rear flap is folded inwardly, the diaper body is wound into a roll toward the front flap, and then the water-soluble resin of the first and/or second engaging elements is dissolved with water. Then the first surface fastener members are pressed against the second surface fastener member to fasten the diaper body in roll as waste.

  • Patent number: 5985396
    Abstract: The present invention is directed to a flushable water-sensitive film, which maintains its integrity and strength when in use, but disperses when place in contact with water, such as in a conventional sink or toilet. Moreover, the present invention is directed to a flushable release liner, which performs like conventional release papers, but adds the convenience of disposal by flushing in a sink or toilet. The present invention is also directed to products, which contain a flushable water-sensitive film or release liner.

  • Patent number: 5981012
    Abstract: The present invention is directed to a flushable release liner. The flushable release liner is formed by applying a release coating onto at least one surface of a water-sensitive film. The flushable release liner maintains its integrity and strength when in use, but disperses when placed in contact with water, such as in a conventional sink or toilet. Moreover, the present invention is directed to water-dispersible products, including flushable products, which contain the flushable release liner.

  • Patent number: 5968025
    Abstract: An absorbent article containing a liquid pervious topsheet coated with a lotion composition is disclosed. The lotion composition comprises a plastic or fluid emollient such as mineral oil or petrolatum, an immobilizing agent such as a fatty alcohol or paraffin wax to immobilize the emollient on the surface of the topsheet, and optionally a hydrophilic surfactant to improve wettability of the coated topsheet. Because the emollient is substantially immobilized on the surface of the topsheet, less lotion is required to impart the desired therapeutic or protective lotion coating benefits.

  • Patent number: 5885264
    Abstract: A disposable training pant 1 includes a liquid-permeable topsheet, a liquid-impermeable backsheet and an absorbent core disposed therebetween. The liquid-permeable tophseet includes an upper layer sheet and a lower layer sheet. The upper layer sheet is formed with a wetness telling area and the lower layer sheet intermittently bonded to the absorbent core 13 and containing fibrous material adapted to shrink by 10% or more longitudinally of the training pant as it is wetted and intermittently bonded to the absorbent core and thereby intensify a feeling of wetness given to the infant.

  • Patent number: 5830201
    Abstract: A flushable diaper for use on the body of an infant or adult. An envelope has inner and outer walls which are secured together at their outer periphery to form an inner cavity. The outer wall is comprised of a hydrophobic outer layer together with a hydrophilic inner layer. The inner wall is comprised of a hydrophobic outer layer together with a hydrophilic inner layer. The inner and outer walls are separated by an interior cavity which contains one or more containers. The container is comprised of either a single layer or a laminated wall which forms a chamber that encloses a charge of water. The laminated wall is comprised a hydrophobic inner laminate and a hydrophilic outer laminate. When manually ruptured, the containers release water into the double walled envelope, which causes disintegration of the hydrophilic inner layers of the double walls, along with the hydrophobic outer layers.

  • Patent number: 5700553
    Abstract: The present invention is directed toward a multilayer film which includes a first surface layer and a second surface layer. The first surface layer is composed of materials which disintegrate when subjected to conditions present in conventional sewage systems. The second surface layer is formed from a material which is essentially inert to water, urine and other bodily fluids. Typically, the second surface layer is an extremely thin coating which provides a waterproofing effect. The multilayer film may be utilized as an outer cover in a wide variety of products such as, for example, disposable diapers and feminine care products such as sanitary napkins.

  • Patent number: 5700476
    Abstract: The invention provides wound dressing and/or implant materials comprising a matrix structure of sponge, at least one substructure and at least one pharmacologically active agent, wherein both the matrix structure and the substructure are formed from bioabsorbable biopolymer materials. The substructure may, for example, comprise biopolymer films, flakes, fibres or microspheres embedded in the matrix structure of sponge. The pharmacologically active agent may comprise antiseptics, antibiotics, analgesics. One or more such active agents may be incorporated separately into the matrix and/or the substructure so as to achieve controlled or phasic release of the active agents into the wound.

  • Patent number: 5700477
    Abstract: Heteromorphic sponges are described which have matrix structures with oriented substructures added to facilitate cellular invasion. A sponge may be used as a wound implant by cutting it to the shape of a wound bed and placing therein. The matrix structure provides conduits which assist invasion of the sponge by cells which degrade the sponge and lay down new tissue to replace it. The incorporation of active agents in the matrix and/or substructures enhances wound healing.
