A container defining a longitudinal axis and a transverse direction that is transverse with respect to the longitudinal axis. The container includes a finish and a sidewall portion extending from the finish. A plurality of ribs are defined by the sidewall. A base portion extends from the sidewall portion and encloses the sidewall portion to form a volume therein for retaining a commodity. The base portion has a contact surface for supporting the container. A plurality of straps extend radially along the base portion away from the longitudinal axis in the transverse direction, each one of the straps defines a strap surface that is closer to the finish than the contact surface. The plurality of ribs and the base portion are configured to place the container in a state of hydraulic charge-up when top load is applied to the container after the container is filled.

Lightweight container base

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.
