Description

COOLING RESERVE.

  The present invention relates to a cooling reserve or cooling tube intended in particular, but not exclusively, for the cooling of liquids and in particular of drinks inside a container. Such cold stores are known which consist of a hollow parallelepipedic envelope, generally of plastic material inside which water or a liquid is introduced, the assembly then being placed in the "freezer" compartment of a refrigerator or freezer. After freezing the liquid, the assembly is removed from the refrigerator and can be used to lower the temperature of a portable cooler in order to keep the food introduced into it at a temperature allowing their conservation for a certain time, in general

a few hours.

  But we cool the product packaging and not the product itself. Furthermore, it is not desirable for the plastic envelope to come into direct contact with the

food.

  For drinks, it is generally used to refresh them by putting ice cubes in the glasses. But by melting the ice turns into water and

may spoil the drink.

  A first object of the invention is to overcome these drawbacks by allowing a drink to be refreshed without altering it. According to the invention, the refreshment reserve for beverage is characterized in that it is constituted by a tubular container made of hermetically sealed glass and

  containing a liquid which can be frozen.

  This reserve is thus reusable and presents all

guarantees with regard to hygiene.

  According to another characteristic of the invention, the reserve has at its upper part a seal

to close a bottle.

  Other characteristics and advantages of the invention

  will appear during the following description of a

  particular embodiment, given only by way of nonlimiting example, with reference to the drawings which represent: - Figure 1, one according to the invention inside a bottle;

  - Figure 2, an alternative embodiment.

  In the figures, the same references designate the same elements. In FIG. 1, it can be seen that the cooler consists of a tube 1, advantageously made of borosilicate glass which can withstand thermal shocks greater than 100 (practically from -35 to + 70 ° C.). The resistance to physical shock is around 360 bars which avoids any risk of accidental breakage. This tube ends at its upper part with a plug or hollow bulb 2, blown, which is intended to constitute a decompression chamber. Above the bulb 2 is formed a substantially cylindrical socket 3 allowing the cooler to be manipulated without touching the body 1. The tube 1 is, before it is closed, filled with demineralized water, which makes it possible to keep the transparency of the whole, when the water is thawed. But any other liquid with suitable characteristics, for example of

  colors, can, of course, be used.

  The volume of water increases, as known per se by 10% when it is thawed and the excess of the volume of liquid by

  in relation to the solid volume is introduced into the bulb 2.

  The tube was introduced into a Bordeaux type B bottle but it can be placed in any other container such as decanters, buckets, jugs, etc. According to another characteristic of the invention and, as shown in Figure 2, the tube 1 is advantageously provided at its upper part with a ring 4 for closing the container in which the tube is introduced. This container can thus be closed in a sealed manner after withdrawal of a quantity of liquid equal to the volume.

  outside of the tube which facilitates transport.

  The cooler according to the invention can be decorated by conventional means, the engravings or inscriptions being preferably made on the bulb 2 which is the part

remaining apparent.

  It goes without saying that many variations can be made, in particular by substitution of technical means

  equivalent, without departing from the scope of the invention.
