Claim:
A plastic container comprising: an upper portion including a finish defining an opening into the container; a lower portion including a base defining a standing surface; a sidewall extending between the upper portion and the lower portion, the sidewall defining a longitudinal axis; at least one substantially transversely-oriented pressure panel located in the lower portion, the pressure panel being movable between an outwardly-inclined position and an inwardly-inclined position to compensate for a change of pressure inside the container; a dimple ( 248 ) centrally located within the pressure panel; and a plurality of radially spaced tapered ribs ( 250 ), each of said plurality of tapered ribs tapering between a narrowest part and a widest part of each said rib, the narrowest part being radially outward of said widest part, the widest part being arranged adjacent the dimple, wherein the standing surface defines a standing plane, and the entire pressure panel is located between the standing plane and the upper portion of the container when the pressure panel is in the outwardly-inclined position, and wherein each of the tapered ribs is generally trapezoidal in plan view with the widest and narrowest parts defining bases of the trapezoid in the plan view.
