METAL PILFER-PROOF CAP

摘要

A metal pilfer-proof cap (1) formed so that a pilfer-proof band (15) remains in ring shape at the mouth part of a container, wherein the upper side of a shear plane at horizontal slits (16) is offset in the inner radial direction of the cap to form a bridge (17) on the upper side of the shear plane, and the inner diameter of the upper end part of the pilfer-proof band (15) is increased larger than the maximum outer diameter of the annular swelled part (22) of the container mouth part for locking the pilfer-proof band (15) thereto, whereby the residue of the bridge (17) can be prevented from remaining on the pilfer-proof band (15) separated from the cap (1) and a large clearance allowing the unsealing of the container to be identified at a glance can be formed between the cap (1) and the pilfer-proof band (15) when the container is re-sealed by the cap (1).
