A plastic bottle for holding liquids such as carbonated beverages under pressure. The bottle, a one-piece, self-standing biaxially-oriented plastic container, is generally cylindrical in body configuration with a spherical bottom from which several lobes or feet extend for supporting the bottle upright on a surface. The feet are also spherical in configuration and extend downwardly from the container bottom adjacent to the sidewall of the cylindrical body to support the bottle in a more stable upright position. The center of the bottom of the bottle may be depressed inwardly into the bottle to increase the clearance between the bottom and a surface on which the bottle stands. The configuration of the bottle serves to impart adequate strength and good resistance to eversion. The bottle can be made with a minimal amount of plastic for given performance characteristics, and at speeds that are economical, even for relatively small bottles.

A self-standing, biaxially-oriented, plastic bottle having a body with a generally vertical wall of substantially circular cross-section, said bottle having a bottom depending from said wall, said bottom being formed integrally with said body and having a principal spherical surface, said bottom having at least three depending feet positioned around the periphery of said bottom on which feet the bottle stands vertically on a horizontal surface, the lower portion of said feet being of substantially spherical configuration, said feet having a wall portion above said spherical portion with the outer periphery of said wall portion taken from the center of the bottle being in substantial vertical alignment with the wall of said body, said principal spherical surface of said bottom extending between adjacent said feet and inwardly of said feet toward the center of said bottle.
