METHOD OF PRODUCING A POLYESTER RESIN CONTAINER AND DEVICE FOR PERFORMING SAME

摘要

The invention relates to a method of producing a polyester resin container, such as a PET bottle, from a preform (10). The inventive method comprises a step whereby the aforementioned preform (10) is heated to a temperature above a glass-transition temperature and a drawing step which is performed in a cavity (101). According to the invention, during the drawing step, an incompressible fluid and not a gaseous fluid is injected through the opening in said preform (10').
