Abstract
The reinforcement of a blow molded base of the type including a generally hemispherical configuration interrupted at circumferentially spaced intervals by protruding legs. Prior cracking problems at the intersection of the foot-radii of such legs with the generally hemispherical portion are solved by an internal reinforcement of the base in that area. The reinforcement may be either localized with the points of reinforcement being circumferentially spaced and in alignment with the legs, or may be in the form of a continuous band. The reinforcement is effected by providing a preform from which a container employing such base is blow molded and wherein the preform is provided either with internal ribs or an internal band of reinforcement and the resultant containers are blow molded in the same mold as previously utilized.
