Abstract
A child resistant safety closure including a body portion defining a chamber, a hollow neck extending from said body portion and having an outside surface, and a container screw thread formed on said outside surface of said neck and extending circumferentially around an axis. A ring encircles said neck of said container and has an outer ring surface and an inner ring surface. A cap having an inner cap surface and a cap screw thread formed on said cap inner surface engages said container screw thread when said cap is twisted onto said container. A pair of interface surfaces located between said inner ring surface and said outside surface of said neck, and between said inner cap surface and said outer ring surface supports a safety mechanism that includes a lug and a recess, which slides over said lug, and two sets of ratchets, which engage each other more closely as said recess slides over said lug, but which slide over each other when said recess is prohibited from rotating.
