1. A container comprising:
an opening defined by a finish portion; and
a base at an end of the container opposite to the opening, 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 an displaced position subsequent to 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 closer to the opening than in the as-blown position,
wherein:
in the as-blown position the inner sidewall and the outer sidewall are arranged at an acute angle;
in the displaced position the inner sidewall and the outer sidewall are arranged at an obtuse angle that is 3.3-11.5 times greater than the acute angle at which the inner sidewall and the outer sidewall are arranged in the as-blown position;
in the displaced position the outer sidewall of the deep base ring is angled 91°-130° from the standing surface, and the standing surface extends perpendicular to a longitudinal axis of the container;
in the as-blown position the inner sidewall and the outer sidewall are angled relative to each other at a 16°-43° angle; and
in the displaced position the inner sidewall and the outer sidewall are arranged relative to each other at a 143°-184° angle.
