An improved container and closure combination is described. The container has a variety of protrusions from its neck. The closure consists of a cap cover, a tear strip, a double-hinge, and an anchor band. The improvements of the closure include providing for a flexible valve seal, an easier removal apparatus for the tear strip, a self-aligning cap and a double lock bead system.

Hinged closure and container

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.

Tamper resistant & tamper evident closures

Tamper resistant and tamper evident closures

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 described 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.

Safety closures resistant to tampering comprising a 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. The locking member includes a first engaging means which engages a second engaging means 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, or a peel pin, a tamper resistant 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 resists tampering. A tamper resistant safety closure comprising a 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.

An improved safety closure for containers is disclosed; the closure comprises a snap-on cap held in place on a container by a rotary safety ring which must be aligned with the cap in one angular position and pushed downwardly away from the cap before one can remove the cap from the container. The closure is improved by providing an outwardly directed bead on the safety ring which makes it easier to grip and push down (and up) the safety ring. An annular protrusion, added to the underside of the cap, and a circumferential knob, added to the neck of the container, improve the seal of the container. Also, a safety ring and cap assembly which has no lateral opening between the safety ring and the cap is disclosed. This invention describes various ways to incorporate on the closure means for counting the number of uses or doses of the container's contents. Finally, two specific embodiments of the closure, a closure for a powder container and a pipette dropper safety closure, are described with some of the improvements.
