<P>PROBLEM TO BE SOLVED: To solve a problem wherein a structure of a metal mold is complicated as it is necessary to divide the metal mold as a cylindrical filler portion is positioned on a side face of parison, and is closed when the parison is expanded, and it is necessary to complete the filler portion by boring the closed portion, which is troublesome. <P>SOLUTION: In this method of manufacturing the pressure container formed by blow molding, comprising a metallic insert component 2 on its end portion for joining a piping member for supplying and discharging contents, and storing the contents, the cylindrical parison 7 drooping from a die core 6 is received between metal molds 8a, 8b in an opened state, the metal molds 8a, 8b are closed in a state that the insert component 2 having a thermoplastic adhesive resin 5 on an outer periphery of a cylindrical portion 2a is placed in at least a lower end portion of the parison 7, then a diameter of the parison 7 of a part having the insert component 2 is reduced, the parison is adhered to the cylindrical portion 2a through the thermoplastic adhesive resin 5, and then the air is blown into the parison 7 to implement the blow molding. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
