ABSTRACT:
A safety closure system includes a cap removably mounted on the neck of a container and prevented from undesired opening by means of a locking ring mounted on the container neck and which locking ring has means such as tooth engaged with complementary locking means such as notches on the cap. The cap and locking ring also contain positioning means to orient the ring with respect to the cap so as to assure proper engagement of the ring locking means with the cap locking means. During assembly the ring is loosely mounted on the neck and mounting of the cap mounts the ring in place.
