<p><P>PROBLEM TO BE SOLVED: To provide a forming method for a bottle wherein a poor product is not generated even when the positioning for the bottle is shifted in the cutting process of an external layer, and an engaging flange molding process. <P>SOLUTION: This is a processing method for the mouth cylindrical section of a lamination stripping bottle as the molding method for the fastening piece. The lamination stripping bottle of which the diameter is expanded upward from the mouth cylindrical section of the bottle, and has a protruding section which conically extends is blow-molded. Then, the protruding section is cut at a fixed height, and the external layer is cut and removed at a position on the top surface of the mouth cylindrical section from the cut protruding section. Then, the remaining internal layer is bent outward, and is bonded with the top surface of the mouth cylindrical section and the peripheral surface to form the fastening piece. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
