  • Patent number: 9592316
    Abstract: A disposable wearing article adapted to prevent indicators from being transferred to a liquid-absorbent structure and to make the indicators develop the color reaction quickly in response to a discharge of body exudates. A disposable diaper has a topsheet, a backsheet and a liquid-absorbent structure interposed between these top- and backsheets. A surface of a first backsheet facing the liquid-absorbent structure is formed with indicators. The indicators contain a hot-melt polymer, an indicator agent adapted to develop a color reaction and a plasticizing oil. The liquid-absorbent structure has a liquid-absorbent core, a liquid-diffusive wrapping sheet adapted to wrap the core. A hydrophilic bottom sheet is interposed between a bottom surface of the core and a bottom surface region of the wrapping sheet. A dimension in the transverse direction of the bottom sheet is larger than a dimension of a region in which the indicators are formed and smaller than a dimension in the transverse direction of the core.

  • Patent number: 9180058
    Abstract: A disposable wearing article improved so that leakage of body waste can be prevented, a change in color which might develop in an unused state of the wearing article can be inhibited and actually discharged body exudates can immediately cause an indicator to develop a change of color. A disposable diaper includes a topsheet, a backsheet and a liquid-absorbent structure interposed between these top- and backsheets. The backsheet includes first and second backsheets and the first backsheet is formed on its side facing the liquid-absorbent structure with an indicator adapted to develop a color reaction when the indicator comes in contact with at least one of moisture and body exudates. A plurality of such indicators is arranged to extend in a longitudinal direction and to be spaced apart from each other in a transverse direction. The liquid-absorbent structure includes a liquid-absorbent core and a wrapping sheet adapted to wrap the core.

  • Patent number: 8535468
    Abstract: A method and an apparatus are provided for making a disposable bodily fluid handling composite pad having thickness-reduced regions on longitudinally opposite ends. The disposable bodily fluid absorbing composite pad includes a bodily fluid absorbing first pad and a bodily fluid absorbing second pad seperably attached to the first pad. A continuous web having continuous bodily fluid absorbing layer and bodily fluid impervious layer permanently attached together is fed to pass through paired compression rolls to obtain a worked web formed in regions which will become ends of the first pad with thickness-reduced regions. A bodily fluid absorbing web is seperably attached to the worked web to obtain a first composite web. A bodily fluid impervious web, pressure-sensitive adhesive and a separator are placed on the bodily fluid absorbing web of the first composite web to obtain a second composite web from which the composite pad is cut out.

  • Patent number: 8460261
    Abstract: An absorbent article in which a plurality of absorbent components is layered, and the absorbent component on top is peeled off after use. The article is configured to inhibit twisting or wrinkling during use. In the absorbent article, the upper absorbent component is layered on the skin-facing surface of the bottom absorbent component and peelably bonded by the temporal adhesive member. The bottom absorbent component has higher flexural rigidity than the upper absorbent component, and the compression recovery rate of the bottom absorbent component is also set so as to be higher than that of the upper absorbent component. It is thereby possible to prevent the bottom absorbent component from twisting and wrinkling when the upper absorbent component is placed against the discharge area, and after the upper absorbent component is peeled off, the volume of the bottom absorbent component is restored, and comfort during contact thereof with the discharge area is improved.

  • Patent number: 7550646
    Abstract: Disclosed is an absorbent article including: a liquid-permeable topsheet on its skin surface; a backsheet on its garment surface; and an absorbent layer therebetween. First compressed portions and second compressed portions, in which the absorbent layer is compressed together with at least the topsheet, extend longitudinally of the absorbent article. The first compressed portions are disposed symmetrically about a longitudinal centerline of the absorbent article to define a central absorbent portion having the absorbent layer therebetween. The second compressed portions are disposed symmetrically about the longitudinal centerline and spaced outwardly apart from the first compressed portions. When the central absorbent portion is laterally compressed by an external force, resilient portions each defined between each adjacent pair of first and second compressed portions are permitted to exert a resilience against compression on the central absorbent portion.

  • Patent number: 7504552
    Abstract: Disclosed is an absorbent article including compressed grooves (11) and a rear flexible portion (16). The compressed grooves (11) where a liquid absorbent layer (4) is compressed and recessed from the side of a skin surface toward a garment surface are provided to extend in a longitudinal direction of the article so as to approach each other the nearest on a lateral reference line (Ox-Ox) of the article. The rear flexible portion (16) where the liquid absorbent layer (4) is recessed from the side of the garment surface toward the skin surface is provided to extend toward a rear end edge (1d) from a starting point (16a) that is located closer to the rear end edge (1d) than the lateral reference line (Ox-Ox). At least a portion of the rear flexible portion (16) is located between the compressed grooves (11).

  • Patent number: 7122713
    Abstract: Disclosed is an absorbent article including: a liquid-permeable topsheet on a skin surface; and a backsheet on a garment surface. First flexible hinges and second flexible hinges are formed to extend longitudinally of the absorbent article. The first flexible hinges are disposed symmetrically about a longitudinal centerline of the absorbent article to define a central absorbent portion having an absorbent layer therebetween. The second flexible hinges are disposed symmetrically about the longitudinal centerline and spaced outwardly apart from the first flexible hinges to define support portions between adjacent first and second flexible hinges and side portions outside the second flexible hinges. The first flexible hinges facilitate bending of the support portions from the central absorbent portion, and the second flexible hinges facilitate bending of the side portions from the support portions.

  • Patent number: 7034199
    Abstract: There is disclosed an absorbent article including: a liquid-permeable top sheet; a back sheet; and an absorbent core sandwiched between the top sheet and back sheet. The back sheet is formed of a resin film containing an inorganic filler in a resin base material. The back sheet includes: a stretched moisture-permeable region; and a high optical transmittance region having a lower degree of orientation than that of the moisture-permeable region and/or left unstretched.
