Definitions

  • the present invention relates to a packaging of drink to cool its contents.
  • the invention is particularly applicable to cooling of drinks contained in a package Closed type can or bottle.
  • the object of the present invention is to enable the consumption of a drink at the ideal temperature in any place and any time.
  • the first method was put implemented in the French patent application FR-A-2 762 076 which proposes to carry out the refreshing of a canned drink by means of a gas expansion compressed.
  • a gas cartridge to relax is placed in a metal radiator itself placed at inside the bobbin.
  • the gas cartridge occupies approximately the half the volume of the beverage to cool, which is imposed by the amount of gas required for cooling of the drink.
  • the price of comes back from a compressed gas cartridge is high, this which leads to an excessive increase in the price of can.
  • connection device 109 is however complex to manufacture, especially if it is necessary to guarantee a good empty (moving parts by rotation and translation with rubber seal). Such a device is not cheap.
  • US Pat. No. 4,736,599 proposes to make an exchanger 16 (evaporator) content totally inside the container 10 to cool (explicitly described as a can), but insists on the reversible nature of the setting in communication of the exchanger 16 with the adsorbent contained in a tank 22 located under the bobbin 10.
  • This device has at least four valves: two to make the empty 19 then fill 20 the exchanger 16, one to make the vacuum in the reservoir 22 of the adsorbent and one for control the triggering of cooling.
  • structuring ensures the rigidity of rooms 16 and 22 under vacuum and a tube 26 can connect the different elements.
  • This complex construction does not allow certainly not to reach a cost price compatible with a disposable packaging like a can and the reversible nature of the setting in communication contributes to this complexity.
  • This module 11 consists of several rooms, one first 12 which contains the liquid to be evaporated 18 (from water) and a second chamber 14, internal to the first 12, containing desiccants 25 and "traps to 24. Triggering means make it possible to put in contact the water 18 and desiccants 25 which act as a pump for water vapor.
  • This adsorption reaction which cools the first room 12, however causes a significant clearance of heat in the second chamber 14, which can be trapped by particular materials 24 (by phase change or by endothermic reaction).
  • the US Pat. No. 5,048,301 proposes as such to add a thermal insulation (DEWAR type) by a room at vacuum 13 surrounding the chamber 14 containing the adsorbent 25.

  • the cavity 2, containing the liquid L to evaporate under vacuum, is sealed to the package 10, by cold crimping of two cones in one another, collage or any other technical.
  • the internal cavity 2 contains only the coolant L and the vapors of said liquid L, that is to say that the liquid L has previously been degassed before to be introduced into the cavity 2.
  • This degassing can be assured, in particular, by boiling atmospheric pressure followed by boiling by pressure reduction up to a few millibars.
  • the partial pressure in the internal cavity 2 gases other than steam coolant L, before connecting cavity 2 external pumping means is less than or equal to at 3mb. This feature helps ensure good evaporation rate avoiding to limit the reaction evaporation with non-adsorbable gases that would be contained in the cavity 2.
  • cavity 2 is important at look at the cooling rate that one wants to obtain because it conditions the effectiveness of the heat exchange between cavity 2 and the drink cool.
  • the geometry of the cavity 2 favors a large trading area with the drink to cool down for a small volume occupied in 10.
  • the ratio of the volume on the surface of the the cavity 2 is then between 5 and 7 times that of the packaging 10 of the drink.
  • the cavity 2 is of tubular structure, mainly consisting of tubes 3 which form ribs held between they by plates 31.
  • the ribs 3 have a shape 3/4 of a cylinder and lead to a common pipe 4. They contain the coolant L to evaporate.
  • the internal cavity 2 can advantageously present a form of circular arc that follows the shape of the bobbin 10. It is attached to the sides of the bobbin 10 by fixing means 6 composed of claws welded or glued for example.

This arrangement avoids the flow of the coolant L by the connecting means 5 and thus allows to ensure the evaporation reaction which that is the position in which the bobbin 10 is held when connected to the pumping means external (50).
  • connection means 5 which make it possible connect the tube 4 of the internal cavity 2 to the means of external pumping are illustrated in detail on the Figures 5a and 5b.
