A method and apparatus for filling a bottle with an oxygen sensitive liquid such as beer in which the bottle is pre-evacuated, pressurized with pure CO2, over-filled with liquid at constant pressure and then brought back to the proper fill level by injecting pure CO2 and forcing the excess back into the gas pressurized liquid storage tank while the bottle is still coupled to the filling head. After uncoupling, the bottle is transported to under a closure cap applying device at which there are nozzles that project CO2 under the device and over and around ...
A method of filling containers such as bottles with liquid so the liquid has minimum exposure to air, comprising the steps of: storing the liquid in a tank under a space for containing gas at above atmospheric pressure, coupling a bottle to be filled and containing air to a filler head, evacuating said bottle so it contains minimal residual air, filling said bottle with pure CO2 gas at a pressure at least as high as the gas pressure in said tank, and discontinuing said filling, conducting said liquid under the influence of gravity from said tank to said ...
