PURPOSE:To obtain a skin integrated foamed resin article enhanced in the degree of completion by forming a bag body from a flexible thin-walled skin material having a lip structure provided thereto and opening an injection port in such a state that the bag body is received in a mold to inject a foamed resin into the mold from the injection port and clamping the mold to mold the foamed resin. CONSTITUTION:A funnel 13 is inserted in the closed injection port 5 of a bag body 2 and, by inserting the funnel 13, a lip structure 8 is opened by the elastic bending of respective mouth members 7 to bring the injection port 5 to an open state. The inserted funnel 13 is used to inject a foamed resin 15 such as urethane foam into the bag body 2 received in the mold from the injection head 14 of an injection machine. When the funnel 13 is pulled out after the injection of the foamed resin 15 is completed, the injection port 5 of the bag body 2 is automatically closed by the elastic return of the lip structure 8 so as to prevent the leakage of the foamed resin and a rise in internal pressure accompanied by the foaming of the injected foamed resin 15 is added and the injection port 5 of the bag body 2 is not opened to complete molding. Therefore, a molded product incapable of confirming the injection port 5 from appearance is obtained. |
