PURPOSE: To improve collection of liquid drops at the exit of a conduit that often causes problems when distributing a constant quantity of liquid, particularly liquefied gas, through a distributing path.

CONSTITUTION: So that a constant quantity of liquid, particularly liquefied inert gas within a distributing conduit 5, is let out by intermittent opening of an electromagnetic valve 7 to flow into a downstream portion 6 of the distributing conduit at the immediate downstream of the valve 7, and a gas conduit 8 equipped with an electromagnetic valve 9 may release and/or evaporate liquid drops in the downstream portion 6 of the distributing conduit, gas flow is introduced into the downstream portion of the distributing conduit immediately after the valve 7 is closed. This is particularly utilized for inactivating or pressurizing food containers with an inert gas.
