CONSTITUTION: A method for bonding a handle to a PET bottle is as follows. A handle is installed in a jig inside a blow mold. A free form for forming a PET bottle is installed on a stretching bar and is located inside of the blow mold (S12). High-pressure air is supplied to the inside of the free form, and the free form is stretched (S13). When the free form is stretched to a PET bottle joint of the handle and the outer surface of a wing-shaped support, the bonded portion of the PET bottle joint is cooled (S14).
