  • a fluid intended for distribution in the above-mentioned form is pressurized, by introducing, preferably into the outer envelope of the packaging container open at one of its ends, before the introduction of the fluid to be dispensed, a flexible, gas-tight, hermetically sealed pocket, inside which is disposed a cartridge also closed and filled with a propellant in the liquid state, the free end of the container, the closed container thus formed comprising a valve allowing at least the distribution of the conditioned fluid, and causing, after having filled the container with the fluid to be dispensed, the opening of the cartridge and at least partially the passage to the gas state of the propellant which spreads throughout the free internal volume of the bag, under a pressure capable of ensuring the distribution of the fluid surrounding the bag from the valve whose is provided with the container.
  • one causes opening the cartridge by heating the container filled with the fluid to be dispensed surrounding the bag to a temperature sufficient to allow, under the effect of the increase in the internal pressure of the propellant, said opening of the cartridge.
  • the opening of the cartridge could be obtained as a result of its dissolution, after a period of time which can be determined in advance, in a solvent initially placed in the flexible bag.
  • the Applicant Company sought to further simplify this process by avoiding either the heating phase of the aforementioned first embodiment, or the use of a solvent, that is to say an additional constituent and a step additional method, in the case of the second embodiment mentioned above.

  • polystyrene is used as the constituent material of the degradable wall zone of the cartridge, the propellant being at least one of the chlorofluorinated hydrocarbons known under the name of "Freons", for example dichlorodifluoromethane (F12), being it is understood that the propellant must not cause cracking by immediate constraint of the cartridge, as in particular trichlorofluoromethane (F11) would do.
  • an agent capable of accelerating the phenomenon of stress cracking is introduced into the cartridge.
  • this agent can be chosen from lower C2-C6 alcohols, for example ethyl alcohol and isopropyl alcohol.
  • the flexible bag is slid inside the container and it is applied against the internal face of the side wall of said container, so that the fluid to be dispensed occupies all the free central part of said container.
