A collapse resistant polyester container is provided for hot fill applications employing product fill temperatures up to about 190.degree. F. (87.8.degree. C.) or more. The container has at least one region which is thermoelastically deformable inwardly after the container is hot filled and sealed to offset the pressure forces which tend to collapse the container as the contents cool and create an internal vacuum. The thermoelastic region is preferably formed in a two step molding process in which the region is formed and heat set at a first position and then reformed outwardly to a second position and cooled in that position.
