PROBLEM TO BE SOLVED: To provide a manufacturing method for a container having no wrinkles at the bonded section between a body section and a molded section by integrally combining the molded section to the film cylindrical intermediate body section without using an adhesive. SOLUTION: A mandrel 26 on which a cylindrical body section 21 is placed is fitted in a die 27 having spaces which respectively correspond to an upper molding section 23 and a lower molding section 24. A lower molding section molding space 24a which is surrounded by the proximal end section of the cylindrical body section being placed on the mandrel and the die is partitioned. A spacer 28 is fitted on the die from the upper side of the die, and an upper molding section molding space 23a which is surrounded by the distal end section of the cylindrical body section, the die and the spacer is partitioned. The upper molding section 23a and the lower molding section 24a are communicated by a runner 29, and a molten resin material is poured into the upper molding section and the lower molding section. The upper molding section having a mouth section 22 on the external surface of the end section of the intermediate body section and the lower molding section having an opening section are integrally combined, and the opening section of the lower molding section is closed by a bottom lid 25.
