ABSTRACT:
The present invention provides an apparatus for stretch blow molding a preform into a hollow container having a heat-resistant property, including a heatable blow mold for forming the preform located therein into a hollow container by a biaxial stretching and blow molding process, and a heat setting mold for heat setting the hollow container. The apparatus includes a stretching rod for longitudinally stretching the preform when the stretching rod is forwardly moved in engagement with the inner bottom of the preform. The stretching rod has a cooling medium introducing tube centrally located therein with an outlet port adapted to introduce cooling medium into the interior of the hollow container. The cooling medium introducing tube is surrounded by thermal insulation.
