PURPOSE:To apply printing to a body part by a method wherein thermoplastic resin whose bending modulus of elasticity is within a predetermined range is subjected to blow molding to form a blow bag whose body part cross section is flat and the flat surface of the body part of the blow bag is supported by a press jig to bring the opposed walls of the body part to a mutual close contact state. CONSTITUTION:The pressing surface of a press jig 6 is formed so as to have a flat surface smaller than the projection surface of the body part 1 of a container and narrower than a body part but larger than a printing part. A blow bag whose body part has a flat cross-sectional shape formed by the blow molding of polyethylene, polypropylene, polyvinyl chloride or a thermoplastic elastomer having the bending modulus of elasticity of 500-10000kg/cm<2> is allowed to correspond so that the body part is opposed to the pressing jig 6 and a hanging jig 3 is fixed to a hanging jig fixing part 10 and a mouth part 2 is fixed to a mouth part fixing part 11. When the pressing jig 6 is pushed in this state, the air in the container is discharged from the mouth part fixing part 11 and the body part 1 of the container becomes such a state that the opposed walls thereof come into close contact with each other. Then, a transfer roll 7 is pressed to the surface of the body part 1 under rotation to apply printing to the body part 1. |
