ABSTRACT:
A lockable closure cap has a displaceable catch projection. A centrally located lock cylinder is supported in a cylindrical socket located within the cap. The cylindrical socket has an eccentric collar on which a locking ring carrying the catch projection is supported, and the cylindrical socket is rotatable with the lock cylinder to displace the locking ring via its eccentric collar. A sealing ring is supported on the upper edge of the outer socket for providing a liquid-tight seal while allowing automatic pressure compensation.
