ABSTRACT:
A plastic container comprises a lower base-forming portion that includes a plurality of circumferentially-spaced, generally spherically-shaped segments and a plurality of intervening, circumferentially-spaced, totally convex, hollow foot-forming portions that extend radially from the central bottom portion and downwardly from the spherically-shaped segments to form a clearance for the central bottom portion. The clearance-forming portion of each foot-forming bottom portion includes a compound curved offset formed with opposing radii of curvature of a substantial fraction of an inch, the compound curved offset curving downwardly and outwardly about a center of curvature below the bottom-forming portion before curving about a center of curvature above the bottom-forming portion. Each bottom clearance-forming portion further includes a spherical surface curving downwardly and outwardly from the central bottom portion and member into the compound curved offset and a lowermost substantially planar portion extending downwardly and outwardly from the compound curved offset for formation of one of the supporting feel.
