Abstract: A snap-on tamper resistant lid having a dual locking system to retain the lid on the container. The lid has a top and a depending skirt. A plurality of beads extend inwardly from the skirt and serve as a primary locking device to retain the lid on a container. A plurality of secondary locking ribs are hinged to the skirt below the level of the beads. The secondary locking ribs have a distal end or edge biased toward the container. Upon initial installation the locking ribs are positioned below the container lip. To remove the lid one must remove the tear strip and the locking ribs. The beads still serve to secure the lid to the container.

Abstract: A tamper resistant container and closure assembly is disclosed. The assembly has an annular protective band which shields the lid from unauthorized access prior to removal of the protective band. The protective band is designed such that it resists manual removal and must be mechanically removed by a can opener or other type of cutting tool. Removal of the protective band allows removal of the lid from the container.
