Abstract
An improved overcap for an aerosol container comprising a top portion interconnected with an annular skirt via a sidewall to form a closed cap which is opened at one end thereof. The skirt contains a release mechanism which has a tab and a leg which, when the tab is biased in a first direction, functions as a fulcrum prying a portion of the overcap adjacent the release mechanism away from a mounting cup of an aerosol container thereby releasing the overcap from the mounting cup. An inwardly facing surface of the skirt contains a rib for engaging an outwardly facing surface of a mounting cup curl while the release mechanism contains a rib for engaging an inwardly facing surface of the mounting cup curl for maintaining the overcap in engagement with the mounting cup. The release mechanism is provided with a pair of frangible members which interconnect with the release mechanism with the overcap to indicate, when broken or fractured, tampering of an aerosol container incorporating the improved overcap.
