    摘要： A polymeric container including an upper portion defining an opening to an interior volume of the container. A base is movable to accommodate vacuum forces generated within the container, thereby decreasing the volume of the container. A substantially cylindrical sidewall extends between the upper portion and the base. A rigid, central pushup portion of the base is at an axial center of the base. A central longitudinal axis of the container extends through a center of the central pushup portion. A flexible diaphragm of the base extends outward from the central pushup portion.

    摘要： 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.
