<p>A closure system for a non-refillable container. In the system, an internally threaded cap (14) is carried in threaded cooperation on the neck (12) of the container (10). Removal of the cap (14) from a capped container (10) is prevented through a combination of locking lugs (30, 32) and camming ramps (35, 36) having end stops (40, 42). Locking lugs (30, 32) can be either on the cap (14) or on the container neck (12) with corresponding camming ramps located, respectively, on either the container neck or the cap. The locking lugs (30, 32) radially flex over the camming ramps (35, 36) as the cap (14) is screwed onto the neck (12) and radially snap back when out of camming relation with the camming ramp. Removal of the cap (14) is prevented by contact of the locking lugs (30, 32) with the end stops (40, 42) of the camming ramps when the cap (14) is attempted to be removed. </p> |
