A container cap assembly provides a tamper-evident component for detecting cap integrity on a container includes one or more elongate bridges connecting a tamper-evident ring to a cap. The cap assembly also provides radially-extending links on the cap and the tamper-evident ring to help protect the integrity of the bridges as the cap assembly is applied to a container.

A package closure system has a frangible radiofrequency identification label which is protected from the external environment by a cover and the frangible label is damaged preventing its normal operation when the package cover is removed. More specifically, a package closure system has a cover, a metallic induction seal attached to the package nozzle and a frangible radiofrequency identification label in which the frangible radiofrequency identification label is attached directly or indirectly to one of its parts on the inner portion of the cover and on another part on the outer portion of the metallic seal.

A container closure and methods are disclosed for providing visible evidence of removal of the closure from a container after installation by a manufacturer. The closure includes tamper evidence bridges comprising small tabs of material that extend from a bottom-most edge of the closure to a tamper evidence ledge of the container. The bridges break when the closure is rotated relative to the tamper evidence ledge, thereby providing readily visible evidence that the closure has been removed after installation by the manufacturer. In some embodiments, a tamper evidence closure engages with threads of a finish of the container. Cam locks around the perimeter of the tamper evidence closure are permanently flared by cams on the finish during loosening of the closure. Outward flaring of the cam locks provides a visual indication that the tamper evidence closure has been loosened after installation by a manufacturer.

In consumer-market containers for beverages or other contents under pressure, the cap provides a gas-tight seal by way of two mechanisms that work interdependently. The first is a pressure grip configured to grip the outside wall of the container. The second is twist threads, or some other second attachment structure, that urges the inside of the cap (or, typically, a cap liner disposed thereon) against the rim of the container. Release of pressurized gases when the container is first opened can be by way of release vents in the cap, or via the bottom of the cap through the twist thread area. In the latter case, particular configurations of the pressure grip are relied on to establish the gas escape path.
