ABSTRACT:
A coupling including a plug attached to a sealed container and having an opening, and a socket having a cutter section for breaking a thin film for sealing the opening when the plug is connected to the socket. The plug has an engagement groove formed in an outer periphery of a plug cylinder, and the socket includes a socket outer cylinder having a lock engageable with the engaging groove, and a socket inner cylinder which is engaged with a smaller-diameter portion of the outer cylinder and is axially movable within the socket outer cylinder. Stoppers are provided within an annular space defined between the socket inner cylinder and the socket outer cylinder. The stopper restricts forward movement of the socket inner cylinder in the state in which the socket is separated from the plug, and the stopper fixes the lock in the state in which the socket is connected to the plug.
