ABSTRACT:
Safety closures resistant to (and evidencing) tampering comprising a snap cap or screw cap, a rotary safety ring, and a tear tab attached to the neck of the container, said closure requiring that the tear tab be removed before the safety ring can be lowered; the safety ring must be aligned with the cap in one angular position and pushed downwardly away from the cap before the cap can be removed from the container. These safety closures may include a tear pin, attached to the cap and to the ring, which must be broken before the cap can be removed from the container; the tear pin may be in addition to, or an alternative for, the tear tab. The tear pin and tear tab are made to be removable. This invention describes a tamper resistant and tamper evident closure comprising a cap having a depending annular flange with a slot therein, and an outwardly directed wing protruding through said slot; the cap cannot be removed without causing the cap to shear off the outwardly directed wing, which is made to be removable. This invention describes a tamper resistant and tamper evident closure comprising a screw cap having an engaging surface located next to a projecting member attached to the neck of the container so that the engaging surface will always shear off the projecting member, which is made to be removable, when the screw cap is first removed from the container.
