Abstract
An apparatus and a method are provided for a container cap comprising a plurality of tamper evidence bridges configured to provide evidence that the container cap has been removed from a container by other than a manufacturer of the container. The tamper evidence bridges comprise a small tab of material that extends from a bottom-most edge of the container cap to a neck ring of the container. The tamper evidence bridges are configured to break, or snap, when the container cap is rotated relative to the neck ring. Broken tamper evidence bridges provide readily visible evidence to an end-user of the container that the container cap has been removed by other than the manufacturer of the container. The high visibility of the tamper evidence bridges serves to discourage vendors from attempting to refill and resale of the used containers.
