A blow-molded container has a central axis, a neck and a cylindrical sidewall connected with the neck, generally centered about the central axis and having an end. A generally hemispherical base wall encloses the end of the sidewall. A plurality of legs extend from and are circumferentially spaced about the base wall. Each leg has a radially outermost portion offset inwardly from the sidewall and toward the central axis. An upper portion of each leg connects the leg with the base wall and has a radially outermost edge offset toward the central axis with respect to the sidewall. Preferably, each leg includes a leg sidewall having a generally cylindrical portion, a first, open end integrally formed with the base wall and a second end. An end wall encloses the second end of the leg sidewall and has a generally flat section providing a foot surface configured to support the container on a surface. Preferably, the leg sidewall has a closed perimeter extending proximal the open end. A continuous blend zone portion extends about the closed perimeter of the leg sidewall and integrally connects the leg with the base wall, the blend zone portion being generally curved and having a center of curvature located externally of the container. Further, each leg is preferably defined in a cross section generally perpendicular to the central axis that has a shape that is generally either circular or ovular.
