Abstract
A method of forming a blown bottle with a handle as a one-piece-molded product, wherein a thermoplastic parison and a handle are held in correct positional relationship by respective holders and are simultaneously moved in a blow mold to be subjected to blow molding. The parison is blow molded by injecting a pressurized fluid into it. Blow molding results in connection of the parison with the handle.
