  • Cap
    Patent number: 10259624
    Abstract: An annular protruding portion (17) is provided around an inner plug (13) at a radial interval on an annular horizontal wall portion (20) of a cap body 4. Between an annular flange portion (43a) of the inner plug (13) and the annular protruding portion (17), an annular accumulating groove portion (33) is provided. Particularly in the case of a liquid content, the liquid content may be scattered from within a cylindrical guide portion (42) when a lid member (5) is placed after use. The liquid content, however, is blocked by the annular protruding portion (17) and prevented from flowing further outward, while interfering with a top surface portion (51) and a cylindrical scattering suppression portion (55) of the lid member (5). Thus, downward flow of the liquid content along the outer wall surface of the annular horizontal wall portion (20) of a main cap member (11) can be suppressed.

  • Patent number: 10232598
    Abstract: A skinned panel for stably molding a thin skin material and a molding method thereof. An extruding device is configured to extrude a pair of multilayered resin sheets, each of which has a lamination structure of an inner layer made of a foamed resin and an outer layer made of a non-foamed resin that is changed into a skin material of a sandwich panel as a skinned panel. The pair of the resin sheets is abutted to the circumferential part of the pair of the split molds for producing sealed spaces. The sealed spaces are sucked for pressing the pair of the resin sheets onto cavities of the pair of the split molds. Accordingly, the pair of the resin sheets is formed in a shape substantially identical to the outline of the sandwich panel.
