In a method for filling bottles or similar containers with a liquid under back pressure, at least a first flushing and a second flushing of the interior of the respective bottle are conducted in chronological sequence during a pre-treatment phase which precedes the actual priming of the respective container, by the timed introduction of a specified quantity of inert gas, with a subsequent evacuation of the interior of the bottle. The introduction of the specified quantity of inert gas takes place in a timed manner during each flushing, and is performed independently of the capacity at which the bottling system is currently being operated.

A method for filling containers with a filling machine, the filling machine being operable at a plurality of speeds of containers per unit time and having a supply tank for containing a supply of a substance with which the containers are to be filled, at least one filling head for engaging the containers, at least one supply passage between the supply tank and the interior of a container engaged by the filling head, a return gas collection duct, a return gas passage between the return gas collection duct and the interior of a container engaged by the filling head, and control means for actuating at least some operations of the filling machine according to determined timed sequences, said method comprising the steps of: feeding the containers into the filling machine; engaging each of the containers with the filling head such that the interiors of each of the containers are in fluid communication with the supply passage and the return gas passage; flushing each of the containers, said flushing step comprising the steps of: preparing each of the containers by at least partially evacuating the interior of each of the containers of gas contained therein; and introducing a specified quantity of a substantially inert gas into the interior of each of the containers during a first determined constant time period; preparing each of the containers for priming by again at least partially evacuating the interior of each of the containers of gas contained therein;. priming each of the containers by introducing an inert priming gas into the interior of each of the containers; injecting the substance with which the containers are to be filled into the interior of each of the containers; closing each of the containers; wherein said step of flushing additionally comprises a second flushing, said second flushing comprising the further steps of: preparing each of the containers by yet again at least partially evacuating the interior of each of the containers of gas contained therein; introducing a second specified quantity of said substantially inert gas into the interior of each of the containers during a second determined constant time period; wherein both of said first determined constant time period and said second determined constant time period are independent of the speed of containers per unit time at which the filling machine is being operated; wherein said steps of at least partially evacuating the interior of each of the containers, again at least partially evacuating the interior of each of the containers, and yet again at least partially evacuating the interior of each of the containers of gas contained therein are carried out such that a relative atmospheric pressure within the container of between about 0.5 bar and about 0.95 bar is achieved, following each of said evacuation steps; said supply tank additionally containing a supply of said priming gas, and said method additionally comprising the further steps of: maintaining said supply of said priming gas contained in said supply tank at a first overpressure (P1); and maintaining said return gas collecting duct at a second overpressure (P2); said first overpressure (P1) being substantially greater than said second overpressure (P2).
