Abstract
A container includes a finish, a shoulder portion, a body, and a base portion. The finish defines an opening. The shoulder portion extends from the finish. The body extends from the shoulder portion and defines a chamber. The base portion extends at an end of the body opposite to the shoulder portion and is moveable from an as-blown position to an expanded position and from the expanded position to a retracted position. The base portion includes a standing ring, a pivot area, and a central area. The pivot area is disposed between the standing ring and the central area. The pivot area is configured to flex and move the central area along the longitudinal axis when the base portion moves from the as-blown position to the expanded position, and from the expanded position to a retracted position.
