Abstract

A polymeric container including a base, a body, a finish, finish threads, and a tamper lip. The body extends from the base. The finish defines an opening through which a product can pass into, and out of, an internal volume of the container defined at least in part by the body. The finish threads are at an outer surface of the finish, and are configured to cooperate with closure threads of a closure to secure the closure to the finish. The tamper lip extends from the outer surface of the finish, and is configured to replace the support flange during handling, and to cooperate with a tamper band of the closure. A recess is below the tamper lip. The recess retains the tamper band therein when the closure is removed from cooperation with the finish.
