Abstract

A blow molded container formed of a polyester resin for use in hot fill applications. The container includes upright side walls, an integral base and a preselected outwardly thermoelastically deformable portion. Upon being filled with a liquid at an elevated temperature, the deformable portion of the container deforms outwardly to partially increase the volumetric size of the container. The remaining portions of the container generally shrink in response to being hot filled.
