Abstract
Abstract A tamper evidencing covering for containers, comprising a hollow container cover and a frangible ring shaped to fit about the cover. The cover includes an external annular retention recess for accommodating the frangible ring, and an annular internal locking bead for affixing the cover to a container. The bead may be segmented, or one or more vertical slots may be provided in the retention recess to relieve the gripping strength of the cover when on a container.
