  • Patent number: 8293969
    Abstract: An absorbent product has a top sheet, an absorbent core and a back sheet. The absorbent core includes 40% by weight or more of high absorbent resin powder and it is possible to slim down the absorbent core while keeping a sufficient amount of absorption to thereby achieve slimming down of the absorbent product. A top sheet lower part contacting the high absorbent resin powder in the absorbent core includes hydrophilic fibers having water retention characteristics, and moisture is temporarily retained in the top sheet lower part before reaching the absorbent core and rapidly disperses in a range facing the absorbent core of the top sheet lower part. As a result, it is possible to reliably absorb the moisture of excrement in the absorbent core and to simplify a structure of the absorbent product.

  • Publication number: 20120253307
    Abstract: A pant-type disposable wearing article includes at least one waist region of front and rear waist regions, which includes an inner sheet lying on the skin-facing side and an outer sheet lying on the non-skin-facing side. The inner sheet has a contractile force higher than that of the outer sheet at least in the transverse direction X. Opposite lateral sections of the inner sheet and opposite lateral sections of the outer sheet are permanently bonded together and extend outward in the transverse direction X from arrays of side seam spots to form front flaps and rear flaps defining protruding rims. The front flaps and the rear flaps are curled inwardly. This article is improved so that opposite side edges do not irritate a wearer's skin even if the wearer's skin comes in contact with these side edges and, in addition, good appearance from a lateral view is assured.

  • Publication number: 20120253306
    Abstract: The present invention aims to provide a disposable wearing article improved so that front and rear waist regions may assure desired fitness without adversely affecting an absorption capacity of a bodily fluid-absorbent core assembly. At least one of front and rear waist regions includes an inner sheet lying on a skin-facing side and having stretch properties and an outer sheet lying on a non-skin-facing side and having a low elastic contractile force. In a section of this one waist region occupied by a liquid-absorbent core assembly including a bodily fluid-absorbent core, the inner sheet is partially cut to define a perforated region. Adhesive used to bond the liquid-absorbent core assembly to the inner sheet and adhesive used to bond the inner sheet to the outer sheet are put in contact with and joined to each other through openings developed by partially cutting the inner sheet.

    Abstract: An improved sanitary pad for use in a thong-style pair of underwear to absorb and retain anticipated menstrual flow volume and at the anticipated flow rate contains a double layer of absorbent material in a waisted, water impervious flexible channel. The waisting of the channel is sized to accommodate the narrow lateral width of the thong saddle. The upright substantially flat or otherwise smooth sides of the channel guide flow entering a capture zone of the pad saddle away from the capture zone to longitudinally outer reservoir zones formed in the front and rear of the pad. In one embodiment flexible guides, which may be longitudinal rails of a flexible water-impervious substance or material, run longitudinally or substantially parallel to the sides of the channel, spaced inwardly therefrom, to assist in guiding or urging flow in and below the capture zone longitudinally towards the reservoir zones.

  • Publication number: 20110270204
    Abstract: A water-absorbent sheet composition containing a structure in which an absorbent layer containing a water-absorbent resin and an adhesive is sandwiched with two or more sheets of hydrophilic nonwoven fabrics, wherein the water-absorbent sheet composition has a structure in which the absorbent layer is separated in divided parts of a primary absorbent layer and a secondary absorbent layer with a water-permeable substrate having a water permeability index of from 20 to 90, and wherein the water-absorbent resin is contained in the absorbent layer in an amount of from 100 to 1000 g/m2. The water-absorbent sheet composition of the present invention exhibits some excellent effects that the water-absorbent sheet composition is capable of accomplishing thinning and avoidance of gel blocking phenomenon and liquid leakage, while obtaining basic properties as a water-absorbent sheet composition at a high level, even for a water-absorbent sheet composition containing a very small amount of pulps.

  • Publication number: 20110218509
    Abstract: A bandage for improved wound care is disclosed. The bandage comprises a non-adherent, deformable inner layer, a leak-proof outer layer that is substantially coextensive with the inner layer, and an absorbent middle layer contacting both the inner and outer layers. An adhesive strip and adhesive tabs along the bandage's side attach and adjust the fit of the bandage to securely hold the absorbent layer in contact with the wound, without any adhesive touching the skin, thereby eliminating pain and discomfort upon removal or replacement. The bandage allows substantial freedom of motion without slipping. The adhesive strip and tabs secure the bandage in place without any adhesive touching the skin, thereby providing convenience and causing no pain or discomfort upon removal or replacement of the bandage. The bandage may use a non-stick netting material layer to improve patient comfort, and elastic cuffs to improve fit and leakage.

  • Publication number: 20110174317
    Abstract: Disclosed herein are articles and processes for making elastic composite structures which can be used as or converted into a component of disposable hygiene products or articles of apparel. At least one relatively inelastic substrate, for example a nonwoven substrate, is adhesively bonded with a hot melt adhesive to a certain selected type of elongated polyurethane material in the form of a film or one or more fibers or filaments. The elongated polyurethane material is then allowed to relax which provides an elastic composite structure which is gathered or puckered.

  • Patent number: 7977531
    Abstract: The present invention relates to absorbent articles that include absorbent compositions which exhibit swelling, deswelling, and reswelling behavior. More specifically, absorbent compositions of this invention swell and absorb fluids after exposure to aqueous fluids, deswell and release fluids from the swollen absorbent compositions, and can also reswell and absorb fluids. The swelling-deswelling-reswelling behavior allows enhanced liquid distribution in absorbent composites and absorbent articles.
