ABSTRACT:
A closure system for a non-refillable container is provided. In the system, an internally threaded cap is carried in threaded cooperation on the neck of the container. Removal of the cap from a capped container is prevented through a combination of locking lugs and camming ramps having end stops. Locking lugs can be either on the cap or on the container neck with corresponding camming ramps located, respectively, on either the container neck or the cap. The locking lugs radially flex over the camming ramps as the cap is screwed onto the neck and radially snap back when out of camming relation with the camming ramp. Removal of the cap is prevented by contact of the locking lugs with the end stops of the camming ramps when the cap is attempted to be removed.
