2. Description of the Related Art Draft beer sold in taverns, etc. is generally filled in tanks (beer barrels made of aluminum etc.) and shipped to each store at the time of factory shipment. A drink dispenser is needed to pour into. This drink supply device includes the tank, a hose having a connection plug detachably attached to the tank, and a dispenser connected to the other end of the hose for injecting and stopping a tank or the like. (Generally referred to as a "dispenser" or "raw server" with a cooling device).

In addition to the above-mentioned draft beer hose, a gas hose connected to a cylinder filled with high pressure carbon dioxide gas is connected to the plug. When the plug is connected to the tank, carbon dioxide automatically enters the tank. The gas is pumped,
Draft beer in the tank is always pushed out to the dispenser.

[0004]

Even if the inside of the tank is emptied, while the hose or the like is filled with draft beer, the state in which draft beer is vigorously discharged by the pressure of carbon dioxide gas continues if the dispenser is opened. However, once the carbon dioxide gas reaches the dispenser, the foamed beer scatters all over the spout, as if a small explosion had occurred at the outlet of the dispenser.
In addition, along with this, even the draft beer in the jug, which had been dispensed under the dispenser, spatters all over and wets the worker's clothes, and the draft beer in the jug is wasted (there is too much foam). There is a drawback that the commercial value is lost).

Further, since the foamed draft beer remains in the hoses and plugs, when the tank is replaced with a new one, it is necessary to wash away the foam by flushing it with subsequent draft beer. About 500 cc of draft beer was wasted. The present invention has been made in view of the above circumstances, and not only prevents the drink filled in the tank from being wasted, but also makes it possible to speed up the replacement of the drink. The purpose is to provide a device.
