PROBLEM TO BE SOLVED: To provide a stop-cock having a plastic-made stop-cock housing provided with an electrically grounding element for the container for transfer and for storage of a liquid.;SOLUTION: The stop-cock 13 accompanying the inflow port 20 of the stop-cock housing 18 is screwed into a connecting flange 21. The connecting flange 21 is designed as a threaded flange and formed of a non-conductivity plastic material and welded to the discharge port 12 of an inside container 2. The connecting flange 21 of the stop-cock housing 18 is connected to the base stand of an outside shell of the container for transfer and for storage via a grounding lead formed from a conductive plastic material. The connecting flange 21 and the grounding lead are manufactured by two steps of manufacturing processes by an injection molding machine using a 2K technology. The connecting flange and a grounding cable are made through injection molding as a single member of electro-conductive plastics, and the grounding cable is connected to the flange ring of the connecting flange with a separation film in the embodiment of other stop-cocks.;COPYRIGHT: (C)2011,JPO&INPIT
