PURPOSE:To provide a method of producing a synthetic resin container with a grip excellent in thermal resistance, by which method even a grip portion can be thermally fixed to the container in a reliable manner. CONSTITUTION:A preform made of synthetic resin is put into a blow mold to perform biaxial orientation blow molding, whereby a neck portion, a body portion and a closed bottom portion are formed. At a part of the body portion, a recessed part 16 is formed, whose deepmost part has a diameter approximately identical to or somewhat larger than that of the neck portion and which is provided with protruding part 20 for engaging with a grip. In this method of producing the synthetic resin container 10 with the grip, the grip 11 whose gripping part 22 and mounting part 23 are unitarily molded by injection molding of a synthetic resin, is fixed to the recessed part 16. The mounting part of the grip 11 is formed as a ring having a shape similar to the protruding part 20, and the gripping part 22 is mounted to the recessed part 16 while at least leaving a spacing from upper and lower faces of the recessed part 16 of the main body of the container 10. Thereafter, it is thermally fixed to them. |
