Title: Filler

Abstract: In a filler, a preliminary substitution in which a carbonate gas within a storage tank is substituted into a vessel interior takes place by opening a first gas discharge valve and a first gas valve, followed by a proper substitution in which a genuine carbonate gas in a chamber is substituted into the vessel interior by opening a second gas valve and the first gas discharge valve while closing the first gas valve, and subsequently followed by a pressurization in which the vessel interior is pressurized to the same pressure as in the storage tank by opening the second gas valve while closing the first gas discharge valve. Subsequently, a liquid valve is opened as the second gas valve is closed and the first gas valve is opened to fill the vessel with a liquid while discharging the genuine carbonate gas in the vessel into the storage tank. In this manner, a filling operation can take place while a carbonate gas of a higher concentration than the conventional practice is substituted into the vessel interior.
