Description

ENVELOPPE REFRIGERANTE
La présente invention a pour objet une enveloppe réfrigérante destinée à conserver des produits à une température déterminée pendant un temps très long.
REFRIGERANT ENVELOPE
The subject of the present invention is a cooling jacket intended to store products at a determined temperature for a very long time.

Il existe dans le commerce des pochettes ou briquettes comprenant une solution d'un gel eutectique, ces pochettes étant disposées dans un compartiment congélateur pendant un temps suffisant pour que la solution de gélifiant soit gelée.There are commercially available pouches or briquettes comprising a solution of a eutectic gel, these pouches being placed in a freezer compartment for a time sufficient for the gelling solution to be frozen.

Le pochette emmagasine ainsi des calories négatives ou frigories, qui peuvent être restituées au contact des substances à refroidir. Mais une telle pochette, à la sortie du congélateur, est rigide et totalement indéformable, de sorte qu'il est difficile d'obtenir un contact intime avec des substances ou des surfaces à refroidir. Les échanges thermiques entre les objets et la pochette présentent un très mauvais rendement
On connaît par ailleurs des nappes frigorifiques, constituées de deux feuilles de matière plastique soudées entre elles à certains endroits, de façon à délimiter une pluralité de sachets indépendants que l'on peut remplir d'une solution de gel. Comme dans le cas précédent, la nappe est disposée avant usage dans un congélateur, ce qui provoque, au bout d'un certain temps, la solidification de la solution.
The pouch thus stores negative calories or frigories, which can be restored on contact with the substances to be cooled. But such a pouch, at the outlet of the freezer, is rigid and completely undeformable, so that it is difficult to obtain intimate contact with substances or surfaces to be cooled. The heat exchanges between the objects and the pouch have a very poor efficiency
Refrigerated sheets are also known, consisting of two sheets of plastic material welded together in certain places, so as to delimit a plurality of independent sachets which can be filled with a gel solution. As in the previous case, the sheet is placed before use in a freezer, which causes, after a certain time, the solidification of the solution.

Grâce aux espaces prévus entre les compartiments, la nappe conserve des possibilités de pliage et de dépliage. Elle peut ainsi réfrigérer ou conserver, à une température assez basse, des objets de forme complexe. Toutefois bien que, grâce aux charnières, les objets de forme complexe puissent être refroidis, les échanges thermiques ne se font que dans de mauvaises conditions et, d'autre part, la capacité de chacun des compartiments est limitée, de sorte que la conservation au froid n'est que d'une durée limitée. Thanks to the spaces provided between the compartments, the tablecloth retains possibilities of folding and unfolding. It can thus refrigerate or store, at a fairly low temperature, objects of complex shape. However, although thanks to the hinges, objects of complex shape can be cooled, the heat exchanges take place only under poor conditions and, on the other hand, the capacity of each of the compartments is limited, so that the conservation at cold is only a limited time.

La présente invention a pour objet de remédier à cet inconvénient et de permettre, par exemple, de conserver des vaccins à une température comprise entre +2 et +60C pendant une durée de 15 à 16 heures dans des emballages de petits formats, par exemple de 20 x 20 cm.The object of the present invention is to remedy this drawback and to allow, for example, to store vaccines at a temperature between +2 and + 60C for a period of 15 to 16 hours in small format packages, for example of 20 x 20 cm.

Selon la présente invention, l'enveloppe réfrigérante, constituée de deux feuilles en matière plastique soudées entre elles, est caractérisée en ce qu'elle comprend deux compartiments d'épaisseur relativement grande, dans lesquels est incluse une solution de gel, les deux compartiments étant réunis par une charnière souple.According to the present invention, the cooling jacket, consisting of two plastic sheets welded together, is characterized in that it comprises two compartments of relatively large thickness, in which is included a gel solution, the two compartments being joined by a flexible hinge.

Les compartiments peuvent être rabattus l'un sur l'autre, à la manière d'une couverture de livre, pour enserrer l'objet à conserver au froid. Par ailleurs, la souplesse des poches permet leur écrasement sur l'objet, ce qui assure un bon contact thermique.The compartments can be folded over each other, like a book cover, to enclose the object to be kept cold. Furthermore, the flexibility of the pockets allows them to be crushed on the object, which ensures good thermal contact.

Ainsi, grâce à l'épaisseur des poches, la capacité volumétrique des compartiments est relativement grande, ce qui permet l'introduction de masse importante de gel, de sorte que la réserve de froid ainsi constituée permette d'atteindre les durées de conservation désirées.Thus, thanks to the thickness of the pockets, the volumetric capacity of the compartments is relatively large, which allows the introduction of a large mass of gel, so that the cold reserve thus formed makes it possible to reach the desired storage times.

D'autres caractéristiques et avantages de l'invention apparaitront au cours de la description qui va suivre d'un mode particulier de réalisation, donné uniquement à titre d'exemple non limitatif, en regard des dessins qui représentent - la figure 1, une vue d'une enveloppe selon l'invention, en
perspective, avant utilisation - la figure 2, une vue de la même enveloppe au cours de
l'utilisation.
Other characteristics and advantages of the invention will appear during the description which follows of a particular embodiment, given solely by way of nonlimiting example, with reference to the drawings which represent - FIG. 1, a view an envelope according to the invention, in
perspective, before use - Figure 2, a view of the same envelope during
use.

On voit sur les figures que l'enveloppe se compose de deux compartiments 1 et 2 réunis par une charnière 3. I1 importe que les grandes surfaces de l'objet O (rigure 2) soient en contact intime avec les compartiments, afin que les échanges thermiques se produisent dans les conditions optimales.We see in the figures that the envelope consists of two compartments 1 and 2 joined by a hinge 3. It is important that the large surfaces of the object O (rigure 2) are in intimate contact with the compartments, so that exchanges thermal events occur under optimal conditions.

Par exemple, les compartiments 1 et 2 peuvent avoir une largeur de 105 à 110 mm et être séparés par une charnière, en forme de bande, de 50 mm. Une telle enveloppe est destinée à entourer l'objet dont la largeur est de 100 mm par exemple.For example, compartments 1 and 2 may have a width of 105 to 110 mm and be separated by a hinge, in the form of a strip, of 50 mm. Such an envelope is intended to surround the object whose width is 100 mm for example.

L'épaisseur des compartiments peut être, par exemple, de 20 mm.The thickness of the compartments can be, for example, 20 mm.

Ainsi, les surfaces inférieure et supérieure de l'objet 0 sont en contact intime avec la paroi interne 4 des compartiments 1 et 2. L'épaisseur de ces compartiments remplis peut varier entre 150 et 200 mm par exemple. De préférence, la face 5 extérieure de l'enveloppe est blanche ou métallisée, de manière à éviter les pertes par convexion. Il est possible de prévoir une face intérieure 4 de l'enveloppe plus fine, plus conductrice ou plus souple que la face extérieure 5.Thus, the lower and upper surfaces of the object 0 are in intimate contact with the internal wall 4 of the compartments 1 and 2. The thickness of these filled compartments can vary between 150 and 200 mm for example. Preferably, the outer face 5 of the envelope is white or metallized, so as to avoid losses by convection. It is possible to provide an inner face 4 of the envelope that is thinner, more conductive or more flexible than the outer face 5.

L'enveloppe proprement dite peut être réalisée en matière plastique se soudant convenablement et ne durcissant pas excessivement au froid, le polyéthylène ou le P.V.C par exemple. Les gels pouvant être utilisés sont nombreux et connus, et notamment des composés de cellulose qui sont inclus dans une solution dans la proportion de 0,5 à 5%, de manière à obtenir une prise en masse suffisante après passage dans le congélateur. Il est bien entendu possible de prévoir des moyens de fixation (non représentés) entre les deux compartiments, et éventuellement, un rebord obturant le -côté resté libre.The envelope itself can be made of plastic material which is welded properly and does not harden excessively in the cold, polyethylene or P.V.C for example. The gels which can be used are numerous and known, and in particular cellulose compounds which are included in a solution in the proportion of 0.5 to 5%, so as to obtain a sufficient solidification after passage through the freezer. It is of course possible to provide fixing means (not shown) between the two compartments, and possibly, a flange closing off the side which remains free.

I1 va de soi que de nombreuses variantes peuvent être introduites, notamment par substitution de moyens techniquement équivalents sans pour mutant sortir du cadre de l'invention.  It goes without saying that many variants can be introduced, in particular by substitution of technically equivalent means without, for a mutant, going beyond the scope of the invention.
