Claim 16:
17. A method for mechanically moving a truncated cone at a center of a base of a thermoplastic container from an as-blown position to a displaced position subsequent to hot-filling and capping the container to reduce an internal volume of the container, in the displaced position the truncated cone is closer to an opening of the container than in the as-blown position, the base including a deep base ring between a standing surface and the truncated cone, the method comprising:
moving a support collar of a displacement device into cooperation with the deep base ring after the thermoplastic container has been blow molded, filled, and capped;
moving a plunger of the displacement device from a retracted position at which a head of the plunger is seated within the receptacle to an extended position at which the head extends out from within the receptacle to allow the head to contact the truncated cone and move the truncated cone from the as-blown position to the displaced position to reduce an internal volume of the container, the head is at an end of a shaft extending through a base of the support collar; and
removing the support collar from cooperation with the deep base ring.
