ABSTRACT:
A safety closure for a container which makes difficult, if not impossible, access to the container contents by a child. A continuous helical thread on a container neck in which thread are formed a plurality of teeth each of which defines an abutment surface transverse to the thread. A cap interiorly threaded for engagement on the neck thread, the cap having adjacent the lower extremity thereof a pawl that engages the abutment on one of the teeth thereby preventing rotation and removal of the cap. The pawl is secured to the cap for resilient movement relative thereto and has a fingernail groove to enable adults to move the pawl out of engagement with the tooth abutments on the container neck.
