Abstract
PURPOSE:To prevent generation of an air rich area or creases in a film, by a method wherein a hot air spouting device spouting hot air toward the film from a part of the inside of a molding tool against which the film abuts first is provided on the part. CONSTITUTION:A parison 10 is extruded through an extruding machine 12, a film 18 is arranged between the parison 10 and a molding tool 14 and blow molding is begun by blowing gas through a blow pin 16. The parison 10 comes into contact with the film 18 and the parison is kept expanding gradually. A hot air spouting device 20 is provided on the central part of the inside of the molding tool and hot air is spouted into a cavity. The hot air abuts first against a film part which is to come into contact with the inside of the molding tool, hot fusion between the film of the part and parison is accelerated through heat of the hot air, and abutting of the film part against the inside of the molding tool is delayed through the hot air. Spouting of the hot air is suspended, then gas within a mold cavity is sucked through a corner part by a gas suction device 22 and the parison 10 and film 18 abut finally against the inside of the molding tool accurately and completely.
