Abstract

A container including an opening defined by a finish portion. A base is at an end of the container opposite to the opening. The base includes a deep base ring between a standing surface and a truncated cone at a center of the base. 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 displaced position, the truncated cone is closer to the opening than in the as-blown position.
