In a method for filling bottles or other containrs under the influence of counterpressure by means of a filling unit, pressurized gas is led into the bottle after terminating the inflow of liquid, with the pressurized gas valve and liquid valve being closed and with a bypass of the gas return tube, and the liquid that thereby remains above the lower open tip of the gas return tube is expelled into a space having a lower pressure than exists in the bottle.

A method of filling containers such as bottles with a liquid, comprising the steps of: providing a tank containing a quantity of the liquid and having a pressurized gas above the liquid, coupling a bottle to a filling device mounted to the tank and pressurizing the bottle with gas derived from the tank through a gas supply and return tube which has a tip in the bottle at a level corresponding to the level at which the bottle should be filled, opening a liquid control valve to begin the flow of liquid to the bottle from the tank concurrently with the gas pressure in said bottle becoming equal to the pressure in said tank for the liquid to displace the gas in the bottle back into the tank through said gas supply and return tube until the major flow of liquid into the bottle is stopped by the liquid level rising in the bottle to the level of the tip of said tube but with an excess of liquid above the level of said tip, blocking said gas supply and return tube against flow of liquid in either direction between the bottle and tank, and opening a conduit which connects to said tank and is independent of the gas supply and return tube to correct the fill level by feeding gas through said conduit at the pressure in the tank to the interior of the bottle while bypassing said gas supply and return tube, and simultaneously connecting the interior of the bottle to a region having lower pressure than the pressure in the tank so the gas fed into said bottle from said tank through said conduit expels the excess liquid in said bottle to said region and then closing said conduit and disconnecting said bottle from said region.
