PROBLEM TO BE SOLVED: To provide fitting for beverage container capable of completely preventing the entry of foreign matter, unclean water, etc., thereby reducing maintenance, and capable of preventing a gas valve from popping out even in the event that the pressure of the inside of the beverage container becomes abnormally high. SOLUTION: The fitting includes a mouthpiece 93 for the beverage container, a valve seat 95 disposed on the internal circumferential side of the mouthpiece, a mounting part 94 disposed integrally with the mouthpiece, a tubular down-tube 5 the upper end of which is supported in the mounting part, the gas valve 3 fitted in the upper end of the down-tube and used for supplying pressure gas into the container, and a beverage valve 4 disposed in the upper end of the down-tube and used to discharge the beverage out of the container. The gas valve in an inclined position is capable of passing through the central hole of the valve seat. The gas valve in a horizontal position cannot pass through the central hole of the valve seat. The shape of the valve seat is a combination of parts of the internal surfaces of cones that have a common central line. The first apex angle of the internal face of the upper cone is greater than the second apex angle of the internal face of the lower cone. COPYRIGHT: (C)2008,JPO&INPIT
