PLASTIC BOTTLE WITH SUPERIOR TOP LOAD STRENGTH

摘要

A plastic bottle has a champagne base that includes a planar standing ring located between a lower margin of a convex heel of the base and a lowermost portion of a central concavity within the standing ring. By making the insid e vertical radius of the convex heel lower margin and central concavity lowermost portion sufficiently small, the bottle is shown to exhibit increased top loa d strength without any increase in plastic. The bottle also has a larger standing ring diameter leading to a more stable bottle.
