Abstract

Abstract A safety closure for preventing access to containers such as drug bottles and the like by children and other irresponsible persons. The closure includes two major parts. One part is a sleeve which is axially secured to the container neck and has an outer threaded surface. The sleeve is free to rotate on the neck. The other part is a cap which may be threaded to the sleeve, but is secured from removal from the container so long as it is threaded on the sleeve. Preliminary rotation of the sleeve is necessary to free the cap for removal in the normal manner.
