an opening defined by a finish portion; and
a base at an end of the container opposite to the opening having a maximum diameter, the base including a deep base ring between a standing surface and a truncated cone at a center of the base, the deep base ring including a hinge from which extends an outer sidewall and an inner sidewall, the inner sidewall forms part of the truncated cone, the truncated cone is mechanically movable a displacement distance from an as-blown position to a displaced position subsequent to hot-filling and capping of the container to reduce an internal volume of the container, in the as-blown position the inner sidewall is opposite to the outer sidewall and both the inner sidewall and the truncated cone are below the hinge, in the displaced position both the inner sidewall and the truncated cone are above the hinge and is closer to the opening than in the as-blown position;
wherein:
the container is made of a polymeric material having an average material thickness of 0.011″ or less; and
a ratio of a maximum diameter of the truncated cone to the displacement distance is less than 2:1.
