ABSTRACT:
A breakaway tamper evident cover for a container such as a spray can is provided with a cap portion and a locking ring portion, the two portions being connected by a frangible tear line. The frangible tear line is ruptured by striking a sharp axial blow to the top of the cap, driving the cap downward into the closure of the container and away from the locking ring. The rim of the cap is provided with an outwardly extending flange which snaps under the interior portion of the container's closure bead to secure the cap to the container while the locking ring remains in place.
