PURPOSE:To make the connection of a bottle main body and a handle strong and stable on the technical subject of that the wall thickness of the engagement and connection part of the bottle main body subjected to stretch molding using the engagement and connection part of the handle as an insert material is made sufficient and moldability is enhanced. CONSTITUTION:By performing the blaxial stretch and blow molding of a bottle main body in such a state that both engagement and connection parts of handle 10 being insert materials are positioned at a center angle of about 90 deg. with respect to the stretching center axis of the bottle main body, the local stretch molding of the engagement and connection parts of the bottle main body is achieved at the beginning of the stretching deformation of a preform 1' and the engagement and connection parts of the bottle main body are molded in relatively large wall thickness with good moldability to strongly and stably connect the bottle main body and the handle. |
