ABSTRACT:
This invention provides a new and simple tamper-resistant, safety closure for a container having threaded neck. It requires the user to align the two arrows, then give it an upward lift while turning in the counter-clockwise direction to unscrew it from the container.
Features of the invention useful in accomplishing the above objects include an outer cap and an inner cap. The interior surface of the outer cap has a plurality of identical protrusions, called the type A protrusions, and one type B protrusion. The exterior surface of the inner cap has a plurality of identical grooves, called the type A grooves, and one type B groove. If the type B protrusion is lifted into the type B groove, then the two caps inter-lock and turning the outer cap in the counter-clockwise direction would also turn the inner cap in the same direction, resulting in the unscrewing of the closure from the container. On the other hand, if the type B protrusion is lifted into one of the type A grooves, then the outer cap will rotate without unscrewing the inner cap from the container.
