ABSTRACT:
An improved tear-up closing device for a container intended for containing a pressurized liquid (e.g., beer), and intended to form a seal over the opening of the container. The novel closing device comprises two parts, viz., (1) an outer part consisting essentially of a tubular body functioning as a gas-tight closure of the opening of the container, and (2) an inner part which defines a pouring opening of the container, this latter consisting essentially of a sealing body. Said outer and inner parts are joined together along a thin, relatively easily breakable wall.
