ABSTRACT Safety closures resistant to (and evidencing) tampering comprising a snap cap or screw cap, a rotary safety ring, and a locking member, usually located below the rotary safety ring, said closure requiring that the locking member 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 (i.e. "opened"). The locking member (e.g., either a second ring or a tear strip) includes a first engaging means (e.g., inwardly directed teeth) which engages a second engaging means (e.g., outwardly directed teeth) located on the neck of the container to which the safety closure is attached. The locking member, prevented from rotation by the engagement of the first and second engaging means, is attached to the rotary safety ring by a connection, which should be broken whenever the closure has been tampered with. The connection may be a fragile tear pin, designed to break when a sufficient rotary force is applied to the rotary safety ring, or a peel pin, being resistant to breaking when said safety ring is rotated relative to said locking member but allowing said locking member to be peeled from said safety ring. A tamper resistant and tamper evident safety closure comprising a snap cap, capable of being removed only when a thumb tab extends past an annular ridge, that engages (via, e.g. a peg or a breakable arm) a snap off ring that is prevented from rotating by engaging the annular ridge; the breakable arm or peg evidences (and resists) the tampering. A tamper evident and tamper resistant safety closure comprising a snap cap (or a screw cap) and a rotary safety ring and a cylindrical sheath, being peelably attached to the safety ring and preventing the safety ring from being lowered as long as the sheath is between the safety ring and a circumferential shoulder.
