The invention concerns a method for packaging liquid products in thin-walled packages providing said packages with good mechanical strength which consists in introducing in the liquid, using an injector (22), an inert gas such as nitrogen, and/or carbon dioxide, in gaseous phase, wherewith the liquid is saturated or supersaturated, storing the resulting product in a reservoir (14), at a constant level above which is generated a blanket of said gas at constant excess pressure, using regulating means. The product is transferred at will by tapping means (4), to packages which are partly filled with product whereof, after the package is sealed, the surface is topped with a blanket of said excess pressure gas. The invention is useful for packaging liquids in particular food liquids.
Pour conditionner des liquides dans des emballages à paroi mince en conférant à ces emballages une bonne résistance mécanique, on introduit dans le liquide, au moyen d'un injecteur (22), un gaz inerte tel que l'azote, ou/et du gaz carbonique, à l'état gazeux, dont on sature ou on sursature le liquide; le produit obtenu est emmagasiné dans un réservoir (14), à un niveau constant au- dessus duquel est créé un ciel dudit gaz à une surpression constante, grâce à des moyens (3) de régulation. A la demande, ce produit est transféré, par des moyens de soutirage (4), à des emballages que l'on emplit partiellement de produit dont, après scellement de l'emballage, la surface est surmontée d'un ciel dudit gaz en surpression. Utilisation: conditionnement des liquides notamment alimentaires.
