ABSTRACT:
The invention contemplates a method of making a child-resistant safety cap, locking ring and container-neck combination, wherein the container may be formed of multiple metal parts, wherein the locking ring is assembled to the neck, and wherein the cap has a threaded engagement to the neck, with releasable ratcheting one-way engagement between the cap and the ring, in approach to the closed relation of the parts. The particular feature of the invention resides in the manner in which a resilient plastic locking ring is assembled to the neck part of the container in axially located and angularly keyed relation to the neck part.
