Abstract
An improved base configuration for a plastic container used in hot-fill applications. The base is concentric with the side walls of the container and an outer ring of the base is connected to a central dome portion which extends upwardly into the body cavity of the container and terminates in a central disk region, which is also generally concentric with the side walls of the container. Radiating in a substantially spiral fashion, from the central disk downward along the dome to the outer ring, are a number of reinforcement ribs and slides which increases the amount of material in the base which is sufficiently oriented and able to resist the deformation induced by unrelaxed retractive stresses during filling of the container with a liquid of elevated temperature.
