ABSTRACT:
Quantities of liquid are distributed via a conduit (5) connected to a source (4) of the liquid, by periodically opening and closing a closure member (7) disposed in the conduit, and injecting, during a predetermined period, immediately after the 5 closing of the closure member (7), a quantity of gas into the conduit portion (6)immediately downstream of the closure member. The duration of the cycle between two successive openings of the closure member (7)is less than 0.1 second. The liquid is an inert liquefied gas, e.g. nitrogen or argon. The injected gas is the same as the liquefied gas and comes from a same cryogenic receptacle (1). The invention is useful for rendering inert or pressurizing containers of food products.
