Abstract
A blow molded plastic bottle has a reinforced plastic bottom with a concave central portion and a bottom rim portion. A solid depending rib, formed at the pinch off seam, extends across the concave portion, and depending hollow ribs, formed in the concave portion at ninety degress to the solid rib, extend radially to the bottom rim portion. The hollow rims effectively reduce the depth of the bottom rim intermediate the seam junctions to reduce bulging of the concave base thereby preventing instability.
