Abstract
A molded plastic bottle has a base having an outside surface rotationally symmetric about a longitudinal axis of the bottle including a convex heel and a central concavity separated by a standing ring supporting the bottle on an underlying surface. The convex heel has an upper margin integrally formed with the sidewall of the bottle and a lower margin defining an outer portion of the standing ring. The central concavity includes a first surface having a lower most portion defining an inner portion of the standing ring. The standing ring inner portion and outer portion intersect in an abrupt edge with the inner portion of the standing ring generally being inclined with respect to the plane at an angle of between about 30° and 50°.
