  • it is also known in particular ( DE 100 64 954 A1 ) in sealing position on the filling element arranged bottles in a the actual filling phase preceding rinsing phase to remove air entrained in the bottle interior with a purge gas in the form of a CO 2 gas, the purge gas centric here, ie in a vertical Baselementachse in the interior of the bottle initiate and dissipate out of the bottle interior via a controlled gas path.
  • the object of the invention is to provide a method which, in particular in containers in the form of cans allows effective flushing of the container or can interior. To solve this problem, a method according to claim 1 is formed. A filling machine is the subject of claim. 9
  • a peculiarity of the invention is that when flushing the respective container, the introduction of the purge gas exclusively via a throttle of the second gas path (22) with reduced flow cross-section and the discharge of the purge gas from the respective container via the first gas path (26) with a much larger Flow cross-section, so that the purge gas flows despite a high throughput of the respective container with reduced purge gas pressure, ie this case in the container only a reduced pressure (compared to the ambient pressure) of about 0 bar to 3.0 bar, for example from about 0 bar to 2, 0 bar (overpressure) preferably from about 0.5 bar to 1 bar prevails.
  • the second gas path 22 has its full, not reduced by the throttle flow cross-section, whereby a rapid biasing and filling of the container is achieved.
  • Containers in the context of the invention are in particular cans, including those which are commonly used for drinks, but also can-like containers in which the cross section of the container opening is only slightly smaller than the cross section of the container interior.
  • the same method is also advantageous for the inert gas flushing of bottles.
  • pressure filling is generally to be understood as meaning a filling process in which the container to be filled rests in sealing position against the filling element and, as a rule, before the actual filling phase, ie before the liquid valve is opened via at least one controlled element in the filling element trained gas path with a pressurized gas clamping gas (inert gas or CO 2 gas) is biased, which is then increasingly displaced during filling of the inflowing the container contents as return gas from the container interior, also via at least one controlled, in the filling element trained gas way.
  • This pretensioning phase is preceded by further treatment phases, in particular flushing of the container interior with an inert gas, for example with CO 2 gas or nitrogen, and likewise via the gas path formed in the filling element.
  • the in the Fig. 1 Generally designated 1 filling machine is used for pressure filling of containers 2 in the form of cans with a liquid product, such as beer or soft drinks.
