<p><P>PROBLEM TO BE SOLVED: To provide a connector for liquid supply from a tank, which is not obstructive because it has no projecting parts when not in use, and which maintains a hermetic plugged state when not in use. <P>SOLUTION: A plug setting hole 55 for liquid supply and a plug setting hole 56 for gas/liquid delivery are provided in a drum cap that is screwed onto the neck of a liquid tank. Within the plug setting hole 55 for liquid supply, a liquid plug 57 having a siphon tube 59 extending to the bottom of the tank is installed so that its top face does not project from the top face of the drum cap. WIthin the plug setting hole 56 for gas/liquid delivery a gas/liquid combination plug 70 is installed so that the top face does not project from the top face of the drum cap. Caps 62 and 75 are removably fitted on the liquid plug and gas/liquid combination plug, respectively, so as to tightly close the upper openings of the respective plugs. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
