PLASTIC BOTTLE WITH CHAMPAGNE BASE

摘要

A molded plastic bottle (10) has a base (24) having an outside surface rotationally symmetric about a longitudinal axis of the bottle including a convex heel (26) and a central concavity (28) separated by a standing ring (30) supporting the bottle on an underlying surface (S). The convex heel has an upper margin (32) integrally formed with the sidewall (22) of the bottle and a lower margin (34) defining an outer portion (36) of the standing ring (30). The central concavity (28) includes a first surface (40) having a lowe r most portion (42) defining an inner portion (44) of the standing ring (30). The standing ring inner portion (44) and outer portion (36) intersect in an abrupt edge with the inner portion (44) of the standing ring generally being inclined with respect to the plane (S) at an angle of between about 30~ and 50~.
