Abstract: A child-resistant screw-on closure is provided with the closure having a closure state indicating pattern and formed as a three-element closure. The outer cap is arranged for rotation relative to the centrally located middle cap and cooperates in a torquing manner with the middle cap so that, as the closure is rotated to close the container, an indication of full sealing is viewable through a window of the outer cap only when such sealing is complete. Similarly, during rotative unsealing or opening of the container, the outer cap is the first to move relative to the remainder of the closure so that the indication of complete sealing of the container is no longer viewable through the window just as soon as rotative opening of the container has begun. Thus, the closure provides the user with a readily apparent indication as to whether the container closure is in its fully closed or container-sealing condition.

An extending neck portion of the container and a peripheral wall of the lock ring positioned over it, both have an offset axis displaced about the same distance from a central axis of the mating threads on the closure and the container. These offset axes are positioned in alignment to permit closure removal when an alignment bar portion of lock ring is in contact with a shoulder of the annular slot in the neck portion of the container. Serrations on the outside serrated surface of the lock ring and the inside serrated surface of the closure, are concentric with the threads on the closure and the container when the offset axes are in alignment.
