Patent attributes
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.
