  • Patent number: 6730258
    Abstract: A window for automobiles or the like, including a frame member which is composed of a thermoplastic synthetic resin material and formed integrally with a window plate. The frame member includes a substantially U-shaped cross-sectional portion formed of lip and web sections which are spaced from and opposed to each other on outer and rear surfaces of the window plate, respectively, and connected with each other by a bridge section having a continuous hollow inner space therein. The frame member is formed by injecting into a mold cavity a relatively small amount, as compared with the volume of the mold cavity, of molten thermoplastic synthetic resin material, and by injecting compressed gas into the resin material to urge the resin material against inner surfaces of the mold defining the cavity.

  • Patent number: 6624340
    Abstract: Disclosed in an absorbent article including a main body and leakage preventing walls. The leakage preventing walls extend longitudinally and lie opposite one another transversely. Each wall is formed of a nonwoven fabric having corrugations, the crests and valleys of which alternate with each other in the longitudinal direction. The nonwoven fabric is provided with an elastic member extending in the longitudinal direction for exhibiting longitudinal shrinking force. The elastic member is adhered to the valleys of the corrugations of the nonwoven fabric with an adhesive. The adhesive is applied to the surface of the elastic member in a band or linear shape continuous in the axial direction of the elastic member and appears regularly or at random at an interval on an arbitrary line which is set on the surface of the elastic member to extend parallel to the axial direction.

  • Patent number: 6508796
    Abstract: There is disclosed an absorbent article including: a main body; and leakage preventing side walls extending in the longitudinal direction of the main body and lying opposite one another in the widthwise direction of the main body. Each leakage preventing side wall has a raised portion which is joined at a root end onto a liquid-receiving side surface of the main body and raised therefrom to have a free end positioned apart from the liquid-receiving side surface. Each leakage preventing side wall is provided with a first elastically shrinking member for applying an elastic shrinking force along a shrinking action line approaching the free end from the root end as it extends from the two longitudinal end positions of the raised portion of the leakage preventing side wall toward the longitudinally midway position of the leakage preventing side wall.

  • Publication number: 20030014032
    Abstract: A napkin package is difficult to form permanent folding, twisting or corrugation in a leakage preventing wall as folded and wrapped by a packaging sheet, to ensure raising of the leakage preventing wall from a surface of a sanitary napkin after opening the package for achieving satisfactory side leakage preventing effect. A sanitary napkin has longitudinally extending leakage preventing walls on both sides of a liquid absorbing portion. A reinforcement sheet is provided on a surface side of a folded sanitary napkin with covering a portion of the folding line, the reinforcement sheet is bent at a position corresponding to the folding line without forming crease, and portions of the leakage preventing walls located corresponding to the portion across which the folding line extends, are urged onto an outer surface of the bent portion of the reinforcement sheet by the elastic tension force.

  • Publication number: 20020190428
    Abstract: A gas-permeable plug is adapted to be inserted in an insertion hole formed through a part of a casing in an inward-outward direction. The gas-permeable plug has a plug body and a permeable sheet including therein countless minute permeable pores. The plug body is injection molded from a material having rubber-like elasticity and the permeable sheet is integrally bonded to a sheet bonding portion by an anchor operation such that when the plug body is injection molded, at the sheet bonding portion, a part of a heat-melted liquid resin enters the minute permeable pores and/or the permeable gaps in irregular directions by the injection molding pressure and is solidified.
