ABSTRACT:
A self-standing bottle structure particularly suited for pressurized beverage bottles. The bottom end comprises a modified hemispherical portion, a convex central base portion, and an intermediate portion interconnecting the modified hemispherical portion and the convex central base portion. A plurality of convex elongated ribs in the intermediate portion which project inwardly to the base center portion and outwardly to the hemispherical portion form a plurality of legs in the intermediate portion, the legs being of smoothly arcuate concave shape and terminating in rounded portions of the hemispherical portion to form feet which lie in a plane normal to the central axis of the bottle structure and adapted to arrest tensile and bending stresses when subjected to internal fluid pressure and heat to provide a novel creep resistant structure.
