This disclosure relates to a minor change in the bottom configuration of a blow molded container and bottle formed of a plastic material which compensates for shrinkage in the bottom structure due to improper cooling whereby the improper cooling may be advantageously utilized to provide for a marked decrease in the blow molding cycle time.
A blow molded plastic material bottle bottom structure comprising a generally hemispherical outwardly convex bottom wall interrupted by a plurality of downwardly projecting wall portions defining hollow legs terminating in lower feet; said bottom wall having a lower polar portion of a smoothly continuous configuration and upwardly offset from and directly joined to said hemispherical configuration.
