Abstract
The invention relates to a method for manufacturing a self-refrigerating drinks package, characterised in that it includes a step consisting in assembling refrigeration means inside the package, said refrigeration means being composed of a cavity containing a refrigerating liquid able to evaporate under the effect of a negative pressure, means of connecting said cavity to external pumping means by adsorption being provided in the package, partial pressure of the non-adsorbable gases in the internal cavity being maintained below 3 millibar.
Claims15
A method for manufacturing a self-refrigerating drinks package, comprising a step of assembling a refrigeration means inside a package, the refrigeration means comprising a cavity containing a refrigerating liquid able to evaporate under the effect of a negative pressure and providing in the package a connector that connects the cavity to a pump external to the package, wherein the assembly step is performed with the cavity containing the refrigerating liquid in a frozen state.
A method for manufacturing a self-refrigerating package, comprising a step of assembling a refrigeration means within a package, the refrigeration means comprising an evaporator chamber provided with connection means and containing a refrigerating liquid able to evaporate under the effect of a vacuum sustained by pumping means through the connecting means, wherein the assembly step closes the evaporator chamber inside the package with the refrigerating liquid in a frozen state.
