Document Type and Number:
WIPO Patent Application WO/2011/142092
Kind Code:
A1
Abstract:
Disclosed are a metal cap and bottle with a cap, which prevent a liner from falling out when the bottle is opened and enable smooth bottle opening and liner insertion. The metal cap (1) comprises a top plate section (2) disposed in the upper section, and a cylindrical section (3) that substantially hangs from the rim of the top plate section and seals an opening of a bottle after the liner (9) has been inserted onto the inner surface of the top plate section in a non-adhered state. The cylindrical section has: a vent hole (8) in the vicinity of the top plate section, that forms a slit-shaped opening in the peripheral direction and releases internal pressure when the bottle is opened; and a top protruding section (8a) and a bottom protruding section (8b) that are formed by bending the upper opening end and the lower opening end of the vent hole (8) inward in the radial direction of the cylindrical section. The end of the top protruding section is positioned further inwards in the radial direction than the outer rim of the liner when the liner is inserted and is also in the same position in the radial direction as the end of the bottom protruding section or positioned further outwards in the radial direction than said end.
