Abstract
In a packing container (1a) provided with a distribution valve (7), a chamber is provided enclosing the starting components of a system (9) for the anaerobic fermentation of sugars using yeasts, which produce the carbon gas forming said propulsive product. The chamber is composed either of a flexible, gas-tight, hermetically closed pocket (8) or of a small rigid reservoir, which is normally closed by a valve calibrated to open only when the pressure which is established in said reservoir exceeds by a given value the pressure reigning in the interior space of the packing container.
