Abstract
Abstract An enclosure containing the starting constituents of a system (9) for anaerobic fermentation of sugars by yeasts, which is to produce the carbon dioxide gas forming the said propellent product, has been arranged in a packaging container (1a) equipped with a dispensing valve (7). The enclosure consists either of a hermetically closed gastight flexible pouch (8) or of a small rigid storage container normally closed by a valve calibrated to open only when the pressure which is established in the said storage container exceeds by a given value that prevailing in the internal space of the packaging container. <IMAGE>

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
140 words
A method for packing under pressure a liquid or pasty fluid intended to be distributed from a packing container (1a, 101a, 201a) provided with a distribution valve (7, 107, 207), with said fluid to be distributed (1b, 101b, 201b) being placed under pressure by means of a propulsive gas, in accordance with which method the propulsive gas is carbon gas obtained by anaerobic fermentation of a system (9, 109, 209) for fermentation of sugars using yeasts, with the components of said fermentation system (9, 109, 209) being selected qualitatively and quantitatively such that the carbon gas produced creates, inside the packing container (1a, 101a, 201a), a pressure capable of ensuring the distribution of the fluid (1b, 101b, 201b) by said valve (7, 107, 207), wherein the fermentation system is contained in a chamber (8, 108, 208) provided inside the container.
Claim 2
Independent Claim
140 words
A method for packing under pressure a liquid or pasty fluid intended to be distributed from a packing container (1a, 101a, 201a) provided with a distribution valve (7, 107, 207), with said fluid to be distributed (1b, 101b, 201b) being placed under pressure by means of a propulsive gas, in accordance with which method the propulsive gas is carbon gas obtained by anaerobic fermentation of a system (9, 109, 209) for fermentation of sugars using yeasts, with the components of said fermentation system (9, 109, 209) being selected qualitatively and quantitatively such that the carbon gas produced creates, inside the packing container (1a, 101a, 201a), a pressure capable of ensuring the distribution of the fluid (1b, 101b, 201b) by said valve (7, 107, 207), wherein the fermentation system is contained in a chamber (8, 108, 208) provided inside the container.
Claim 3
Dependent Claim
29 words
The method in accordance with claim 1, wherein simple sugars, such as glucose, and complex sugars, such as saccharose, in an aqueous medium can be used as the sugars.
Claim 4
Dependent Claim
16 words
The method in accordance with claim 1, wherein yeasts belonging to the Saccharomyces genus are used.
Claim 5
Dependent Claim
38 words
The method in accordance with claim 1, wherein at least one doping agent, selected in particular from among the vitamins, such as biotine and thiamine is added to the starting components of the fermentation system (9, 109, 209).
Claim 6
Dependent Claim
68 words
The method in accordance with claim 1, wherein, as the chamber in which the starting components of the fermentation system (9) are placed, a flexible pocket (8) is used, which is gas-tight and which is then hermetically closed, with said flexible pocket (8) being such that, once totally inflated, it is capable of occupying a volume at least equal to the internal volume of the packing container (1a).
Claim 7
Dependent Claim
106 words
The method in accordance with claim 1, enabling the distribution of liquid substances, wherein, as the chamber in which the starting components of the fermentation system (109) are placed, a small rigid reservoir (108) is used, which is normally closed by a valve (110), which is calibrated to open only when the pressure which is established in said reservoir (108) exceeds by a given amount that reigning in the interior space of the packing container (101a), with said reservoir (108) being ballasted so that the liquid phase of the fermentation system (109) is always beneath said valve (110), whatever the pressure of the packing container (101a).
Claim 8
Dependent Claim
42 words
The method in accordance with claim 6, wherein, as the chamber in which the starting components of the fermentation system (209) are placed, a small rigid reservoir (208) is used, which in turn is contained in a hermetically closed, flexible envelope (212).
