ABSTRACT:
A safety cap for sealing a container is disclosed. The cap is adapted to a container having a sidewall and annular upper shoulder extending to a neck portion that is threaded. In the vicinity of the neck portion is a cam member having a lug recess in the vicinity of the eccentric portion of the cam.
The cap comprises an inner cup member with an integral continuous sidewall for sealing the container. On the inner cup member's interior surface, threads are formed to mate with the threads on the container. The sidewall has at least one downwardly projecting lug adapted to contact the recess on the cam member when the cap is in its sealing position. Alternatively, the inner cup member can include an inner cup with threads and a middle cup with lugs.
Connected to the inner cup member or molded in one piece is an over cup that has a diameter equal to the span of an adult's hand. This cup is located so that when a force is exerted against it, it transversely deforms and translates the force to the inner cup member. The inner cup member in turn transversely deforms to disengage the projecting lugs from the lug recess on the cam member.
