Abstract
A hermetical stopper used for liquid receptacles made of aluminum including minicasks of beer. Unlike the case in conventional receptacles in which the discharge ports usually have been hermetically sealed with aluminum as the same material for the main body, the hermetical stopper according to this invention is made independently of the main body so as to be able to put into and pull from out the discharge port at will, so that it is possible to be used repeatedly keeping the hermetically sealed state even after the primary use because of the discharge port being not necessary to be cut off purposely from the main body at the time of broaching the receptacle. In this way, this hermetical stopper according to the invention is very commendable also from the point of view of the effective use of resources.
