ABSTRACT:
A more efficient cooling of a blow molded thermoplastic article can be achieved by directing sprays of cooling medium against those specific zones of the wall of the article which require a more rapid cooling while avoiding directing the sprays at areas requiring a less rapid cooling. This cooling procedure is achieved using a spray head having a plurality of individual spray nozzles which direct sprays specifically against the areas requiring more rapid cooling.
