BOTTLE PLUG
Document Type and Number:
Japanese Patent JP2016049999
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To facilitate compliance to the Recycling Law by making the weight of a plug body lighter than that of a crown head body and facilitate unplugging, in a bottle plug consisting of the plug body made of a resin and the crown head body formed of a metal plate.SOLUTION: A plug body 1 is reduced in weight by forming a hollow step part 9 in a flange part 4. The hollow step part 9 is provided with reinforcement ribs 12, 13. By forming end faces of the reinforcement ribs 12, 13 as inclined planes 15 and reducing the volumes of the reinforcement ribs 12, 13, more reinforcement ribs 12, 13 can be formed, and thereby the rigidity of the flange part 4 is improved. A plug part 3 comprises a narrowed part 6 having a curved cross-sectional shape. By setting the curvature radius of the narrowed part 6 to an approximately half of a radius of a cylindrical part 5 or larger, unplugging is facilitated.SELECTED DRAWING: Figure 2
