Abstract (en)
[origin: WO2009053615A2] The subject of the invention is a method of pressurizing a thin-walled container designed to contain a flat liquid, characterized in that it consists in the following series of steps: making a thin-walled container in which residual stresses are set up; filling this container with said flat liquid at a cold temperature; sealing the container after filling it; and heating the wall of the container without raising the temperature of the liquid, to reach the temperature of relaxation of said stresses in such a way that the interior of said container is pressurized. The invention also covers the container produced in this way.
