Lightweight polymeric container finish
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 ring is between the finish threads and the tamper lip. The gripper ring is configured to cooperate with a gripper for grasping the finish.
1. A method for maneuvering and supporting a container and a preform from which the container is blow molded before, during, and after blow molding, the method comprising:
supporting the preform and the container on a surface by positioning on the surface a tamper lip of a finish of the preform and the container; and
grasping the finish with a gripper through cooperation between the gripper and an undersurface of a gripper ring of the finish,
wherein:
the gripper ring is between threads of the finish and the tamper lip of the finish;
the gripper ring is between an upper portion of the outer surface of the finish and a lower portion of the outer surface of the finish;
the upper portion of the outer surface and the lower portion of the outer surface of the finish are equidistant from a radial center of the finish;
the gripper ring is configured as a flange with an outermost portion of the gripper ring being farther from the radial center of the finish than each of the upper portion and the lower portion of the outer surface of the finish; and
a first distance between the gripper ring and the tamper lip is less than a second distance between the gripper ring and threads of the finish.
