ABSTRACT:
A child-resistant closure for a container having a threaded cylindrical neck. The container neck is provided with a plurality of outwardly extending ratchet-teeth on its exterior surface below the thread. The cap portion of the closure has a central opening in its top surface that receives the base of the article to be attached to the container neck, e.g. a trigger pump. A collar member is received on the lower end of the closure member and is axially movable thereon. The collar member is provided with a plurality of ratchet-teeth adapted to engage the ratchet-teeth on the neck of the container when the collar is in its lower or down position. The cap has spaced apart splines on its skirt which define recesses that receive inwardly directed lugs provided at the top of the collar. The engagement of the lugs and splines permit the collar to move axially on the cap but prevents separate radial movement between the collar and cap.
