Abstract
A base including an inwardly and upwardly projecting flexible surface within a continuous seating ring supports a generally cylindrical wall extending upward from the base. A plurality of annular inwardly projecting, and vertically flexible rings interrupting the cylindrical wall. At least one of rings projects inwardly more than some others of the rings to achieve an improved sidewall crush resistance A shoulder portion, includes a plurality of vertical ribs separating a plurality of vacuum responsive panels. The vertical flexibility of the bottle sidewall reduces the amount of flexing required in the shoulder panels and base to accommodate the same vacuum development, and enhances the total amount of post capping vacuum development that can be accommodated by the bottle as a whole.
