ABSTRACT:
A sealing closure for containers, more particularly cans and the like, in which a liquid is stored under pressure and is removed therefrom under pressure. The sealing closure of the invention comprises an axially bored plug-like closing body having a conically tapered outer surface, a flange which is adapted to bear against the container top, and an annular peripheral recess disposed between the flange and the said conically tapered outer surface. A sealing formation is arranged in the bore and comprises two spaced-apart annular projections. An ejectable sealing cap is provided which fits into the lower opening of the bore, as well as a removable closure cap for closing the upper opening of the bore.
