1. A polymeric container comprising;
a base;
a body extending from the base; and
a finish defining 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;
finish threads of the finish that are configured to cooperate with closure threads of a closure to secure the closure to the finish;
a tamper lip of the finish below the finish threads, the tamper lip configured to cooperate with a tamper band of the closure, during blow molding of the polymeric container from a preform the preform is supported by the tamper lip;
a recess below the tamper lip that retains the tamper band below the tamper lip when the closure is removed from cooperation with the finish; and
a gripper retainer of the finish between the finish threads and the tamper lip, the gripper retainer configured to cooperate with a gripper for grasping the finish, the gripper retainer includes a groove defined between an upper flange and a lower flange;
wherein:
the upper flange includes a first upper surface facing the finish threads, a first lower surface that is opposite to the first upper surface, and a first outer surface including a first outermost portion of the upper flange;
the lower flange includes a second upper surface facing the first lower surface and a second outer surface including a second outermost portion of the lower flange, the second outer surface is immediately adjacent to a rounded upper surface of the tamper lip;
both the upper flange and the lower flange extend outward such that the first outermost portion of the upper flange and the second outermost portion of the lower flange are each further from a radial center of the finish than the groove and are each closer to the radial center of the finish than outermost edges of the finish threads;
the first outermost portion of the upper flange and the second outermost portion of the lower flange are each further from the radial center of the finish than an outermost surface of the finish at an area of the finish between the finish threads and the upper flange; and
the groove is recessed inward towards the radial center of the finish such that the groove is an inner-most outer surface of the finish.
