Abstract
A blow molded plastic container for carbonated beverages includes an upper mouth-forming portion, a cylindrical sidewall portion and a lower base-forming portion, all of the portions being generally symmetrically situated about a central longitudinal axis. The lower base-forming portion includes a central portion contiguously surrounding the central longitudinal axis and a plurality of circumferentially-spaced, downwardly convex rib segments, each rib segment extending upwardly from the central portion following a hyperbolic profile and expanding circumferentially outwardly to merge with the sidewall. The lower base-forming portion additionally has a plurality of intervening and circumferentially-spaced, convex, hollow foot-forming portions extending downwardly from the circumferentially-spaced, rib segments. Each of the foot-forming portions has a bottom clearance-forming portion adjacent the central portion and a lower outer portion defined by the rotation of a heel radius greater than 0.8 cm about a central point of each foot situated on a contact radius. The rotation of the heel radius is along a mirrored hyperbolic profile having a coefficient of curvature of between about 0.65 and 0.80 so that the bottom of the foot exhibits essentially no incidence of creases and folds common in prior art containers.
