ABSTRACT:
The invention relates to a pilfer-proof cap, for example for a beer container, which comprises two shell portions (4,6) connected by a hinge (8) incorporating a tear-strip, and capable of being secured around the valve of the container by a non-releasable fastening means (14,16). When authorized opening of the container is required, the tab (12) of the tear-strip is pulled away from the cap and releases the valve for use.
