Abstract

A polymeric container including a base, a body, a finish, finish threads, and a tamper lip. 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 below the tamper lip when the closure is removed from cooperation with the finish. A gripper groove between the finish threads, the gripper groove configured to cooperate with a gripper for grasping the finish.
