Abstract: A container including an opening defined by a finish portion, and a base at an end of the container opposite to the opening. The base includes a standing ring extending inward from a heal to a center pushup portion. The center pushup portion includes an pushup ring surrounding an inversion portion. In an as-blown position the inversion portion extends outward and beyond the pushup ring such that the inversion portion is further from the opening than the pushup ring. In a final position the inversion portion is inverted relative to the as-blown position such that the inversion portion extends inward so as to be closer to the opening than the pushup ring. The inversion portion is mechanically moved from the as-blown position to the filled position with an inversion device after the container has been filled to reduce vacuum or increase pressure within the container.
