Abstract

PURPOSE:To produce a tube which is provided with a seal by means of a hinge at the inside of an exhaust port, by a method wherein a punching male die in an injection-molding mold for tube-molding punches out a continuous film and is inserted into a cavity with the formation of the seal for injection-molding the subject product monolithically thereat. CONSTITUTION:A continuous film 9 put between mold plates 1 and 2 is punched with a punching male die 11 lowered. So obtained seal is inserted into a cavity together with the punching male die 11, and plastic resins are injection-molded in a space provided between the cavity and a core 5. A part of a lower end of the punching male die 11 is notched to form a notched portion 14, and thus, a hinge 17 made of resins is formed at siad notched portion. A seal, which can open and close freely, is attached by means of the hinge 17. This causes the tube to be excellent in virginity and also to be prevented from reverse flow of air, whereby a contained matter is prevented from oxidation change in property.
