METHOD OF FILLING LIQUID

PURPOSE: To maximize the substitution rate of a counter gas by blowing the counter gas into a container, intercepting the container from the outside, sucking the gas in the container to make it vacuum, conducting second-time counter gas blowing, and then filling the container with a liquid. CONSTITUTION: A bottle table 61 lifts a bottle 51, contacts the bottle mouth to a centering bell 50, contacts the centering bell 50 to a packing 62, and inserts a vent tube 58 into the bottle 51. Opening a valve 54 flows a counter gas from the upper part of a tank 52 into the bottle 51. The valve 54 is closed after at least 70% replacement with gas. A button of a pre-ever valve 6 is pushed down by a cam a, and the interior of the bottle 51 is connected to a vacuum ring 53, whereby the inside of the bottle 51 becomes substantially vacuum. Opening the valve 54 again flows the counter gas into the bottle 51 to replace with the counter gas by about 99%. At this time, a liquid valve 56 is opened to start filling. Closing the vent tube 58 closes the liquid valve 56 to terminate filling.
