Tapping armature for a transport and storage container for liquids

A tapping armature for liquid transport and storage containers, which are equipped with a plastic inner container having a closable filling port and a drain port for connection of the tapping armature, a closable filling port and a drain port for connection of the tapping armature, an outer casing made from metal mesh or sheet metal, and a pallet-like base made from metal or a plastic material that is at least partially electrically conductive for supporting the inner container, said tapping armature comprising:

• an armature housing made from plastic;
• a connecting flange constructed as a threaded flange made from an electrically conductive plastic material, to which the armature housing is screwed with the filling port, and with which the armature housing is welded to the drain port of inner container;
• and
• a flexible electrical grounding lead constructed integrally with the connecting flange by injection molding, one end of which grounding lead is connected to the flange ring of the connecting flange via a bridge, and the other end of which has a fixing lug for attaching to the base or outer casing of the transport and storage container, wherein the cable section between the bridge and the fixing lug is connected to the flange ring of the connecting flange by a tear-off film in such manner that after the connecting flange with tapping armature has been welded to drain port of inner container, the cable section of grounding cable between bridge and fixing lug on base or outer casing of transport and storage container may be detached from flange ring of connecting flange.
