Zusammenfassung: | PURPOSE: A bottle cap of a beverage container is provided to prevent a leakage of contents and the deformation of the container caused by fermentation gas. CONSTITUTION: An operational film (12) formed into a recessed groove on the top surface of a bottle cap (11) seals an opening by being in contact with the top of an opening of a container. A pushing protrusion (13) is formed on the bottom surface of the upper part of the battle cap in a circumferential direction and adheres to the top of the opening of the container. The operational film is formed into a circular shape identical to the pushing protrusion. A prevention protrusion is fitted into the top of the opening of the body and prevents a leakage of contents. A volume reducing hole is protruding on the top of the bottle cap to be pushed. A pushing plate of a disc-shaped structure is pushed by a user. An elastic deformation film supports the pushing plate to be pushed by connecting the top of the bottle cap and the pushing plate. |
