Abstract

The invention relates to an isothermal container which is noteworthy in that it comprises at least one compartment at least partly delimited by walls 1 made from a heat insulating material which is permeable to gases, the said walls being provided with a plurality of housings 2 intended to receive blocks of solid gas 3 whose shapes match those of the said housings. The invention is particularly well suited for ensuring that a packaged product is kept within a defined temperature range.

Description

Conteneur isotherme
L'invention concerne un conteneur isotherme.Isothermal container
The invention relates to an insulated container.

I1 existe de nombreux conteneurs ou récipients plus ou moins isolants contre les variations extérieures de température. There are many more or less insulating containers or receptacles against external temperature variations.

Pour cela il suffit, par exemple, de concevoir le conteneur avec une matière en elle-même isolante, ou de créer une paroi munie d'un espace dans lequel on effectue un vide le plus poussé possible.For this it suffices, for example, to design the container with a material in itself insulating, or to create a wall provided with a space in which a vacuum is made as high as possible.

Toutefois, si la plupart de ces moyens connus permettent de retarder un transfert de calories d'un côté à l'autre de la paroi, ils ne permettent pas de maintenir à l'intérieur une plage de température idéale pour une utilisation précise. However, if most of these known means make it possible to delay a transfer of calories from one side to the other of the wall, they do not make it possible to maintain inside an ideal temperature range for precise use.

En effet, il est souvent utile d'assurer le maintien d'un produit conditionné dans une plage définie-de température et pendant un laps de temps également défini, quelles que soient les conditions de température à l'extérieur. Certains produits peuvent en effet se dégrader au cours d'un transport ou d'un stockage temporaire si sa température vient à dépasser et/ou au contraire descendre en dessous d'un certain seuil de température. C'est par exemple le cars de certains produits pharmaceutiques. Indeed, it is often useful to ensure that a packaged product is maintained within a defined temperature range and for an equally defined period of time, whatever the temperature conditions outside. Certain products can indeed deteriorate during transport or temporary storage if its temperature comes to exceed and / or on the contrary fall below a certain temperature threshold. It is for example the coaches of certain pharmaceutical products.

L'inventeur a cherché et a trouvé un moyen susceptible de répondre à cette préoccupation. The inventor has searched and found a way to address this concern.

Parmi certains conteneurs connus, il a été imaginé de prévoir des cavités pour y verser un liquide chaud ou dans d'autres cas, un fluide réfrigérant. Among some known containers, it has been imagined to provide cavities for pouring a hot liquid or in other cases, a refrigerant.

Toutefois dans ces récipients connus, on cherche à dégager par conduction des calories ou des frigories pour réchauffer ou refroidir l'intérieur, sans parvenir à stabiliser une plage de températures. However, in these known containers, it is sought to release by conduction calories or frigories to heat or cool the interior, without managing to stabilize a temperature range.

L'inventeur a imaginé un conteneur isotherme dont les performances sont tout à fait surprenantes. The inventor has imagined an insulated container whose performance is quite surprising.

Le conteneur selon l'invention est remarquable en ce qu'il comporte au moins un compartiment délimité au moins en partie par des parois formées dans un matériau thermiquement isolant, mais permeable aux gaz, lesdites parois étant pourvues d'une pluralité de logements destinés à recevoir des blocs de gaz solidifié de formes conjuguées à celles desdits logements. Ainsi, le résultat d'isothermie est obtenu par sublimation des blocs au travers des parois, laquelle est fonction des températures et des pressions existantes à l'intérieur et à l'extérieur du compartiment. The container according to the invention is remarkable in that it comprises at least one compartment delimited at least in part by walls formed in a thermally insulating material, but permeable to gases, said walls being provided with a plurality of housings intended for receive solidified gas blocks of shapes conjugated to those of said housings. Thus, the isothermal result is obtained by sublimation of the blocks through the walls, which is a function of the temperatures and pressures existing inside and outside the compartment.

Chaque logement présente un volume intérieur légèrement plus grand que le volume du morceau de gaz solidifié à introduire dans ledit logement. Each housing has an interior volume slightly larger than the volume of the piece of solidified gas to be introduced into said housing.

Selon un mode de réalisation, les logements présentent une forme cylindrique et sont ménagés entre et parallèlement aux faces des parois dans lesquelles ils sont formés, lesdits logements étant de préférence disposés selon une ligne brisée entre les faces desdites parois. According to one embodiment, the housings have a cylindrical shape and are formed between and parallel to the faces of the walls in which they are formed, said housings preferably being arranged in a broken line between the faces of said walls.

Il a été trouvé que la plage stabilisée de températures et la durée de conservation sont éventuellement fonction du rapport entre le volume des blocs de gaz solidifié et le volume des parois. de même qu'elles sont fonction de la position des logements dans lesdites parois, de telle sorte que l'on peut jouer sur plusieurs paramètres selon les utilisations envisagées. It has been found that the stabilized temperature range and the shelf life are possibly a function of the ratio between the volume of the solidified gas blocks and the volume of the walls. as they are a function of the position of the housings in said walls, so that one can play on several parameters according to the intended uses.

Chaque logement doit bien sûr être obturé après l'introduction du bloc de gaz solidifié. Il est apparu avantageux que lesdits logements soient obturés par un couvercle prévu aussi pour clore le compartiment. De préférence, le couvercle est également pourvu de logements destinés à recevoir des morceaux de gaz solidifié. Dans ce cas, les logements du couvercle sont par exemple obturés par un rebord aménagé sur les tranches des parois qui reçoivent ledit couvercle. Each housing must of course be closed after the introduction of the solidified gas block. It appeared advantageous that said housings are closed by a cover also provided to close the compartment. Preferably, the cover is also provided with housings intended to receive pieces of solidified gas. In this case, the housings of the cover are for example closed by a flange arranged on the edges of the walls which receive said cover.

Selon une réalisation possible, l'inventeur a également prévu des éléments modulaires destinés à être appliqués sur au moins certaines des parois du compartiment, chaque élément étant formé de la même matière que lesdites parois et ayant des logements équivalents à ces dernières pour recevoir aussi des blocs de gaz solidifié. According to a possible embodiment, the inventor has also provided modular elements intended to be applied to at least some of the walls of the compartment, each element being formed of the same material as said walls and having housings equivalent to the latter to also receive solidified gas blocks.

L'invention sera bien cdmprise à la lecture de la description qui va suivre et qui se réfère aux dessins annexés dans lesquels:
- la figure 1 montre en perspective un conteneur selon
l'invention,
la figure 2 montre un couvercle destiné à venir clore le
conteneur de la figure 1,
la figure .3 montre en partie mais plus dans le détail un
mode de réalisation selon l'invention,
- la figure 4 montre un élément modulaire de contre paroi.The invention will be clearly understood on reading the description which follows and which refers to the appended drawings in which:
- Figure 1 shows in perspective a container according
the invention,
Figure 2 shows a cover intended to close the
container of figure 1,
Figure .3 shows in part but more in detail a
embodiment according to the invention,
- Figure 4 shows a modular element against the wall.

Sur les figures 1 et 3, on peut voir un conteneur sous forme ici d'un parallélépipède rectangle muni de quatre parois latérales, telles que 1 et d'un fond non visible sur les dessins. In Figures 1 and 3, we can see a container here in the form of a rectangular parallelepiped provided with four side walls, such as 1 and a bottom not visible in the drawings.

Tous ces éléments sont formés dans un matériau thermiquement isolant et légèrement poreux ou du moins perméable aux gaz tel que par exemple du polyuréthane.All these elements are formed in a thermally insulating and slightly porous material or at least permeable to gases such as for example polyurethane.

Dans chacune des parois latérales 1, sont ménagés des logements tels que 2, ici de forme cylindrique. In each of the side walls 1, housings such as 2 are formed, here of cylindrical shape.

Les logements 2 sont parallèles entre eux dans le sens de la hauteur et sont avantageusement disposés, comme le montre la figure 3, plus ou moins éloignés de la face interne la de la paroi 1 et de préférence alternativement selon au moins deux distances d et D (figure 3). The housings 2 are mutually parallel in the direction of the height and are advantageously arranged, as shown in FIG. 3, more or less distant from the internal face la of the wall 1 and preferably alternately according to at least two distances d and D (figure 3).

Chaque logement 2 dont l'un d'entre eux est plus particulièrement montré en ligne interrompue sur la figure 3 est destiné à recevoir un morceau de gaz solidifié 3 dont le volume est légèrement inférieur au volume intérieur du logement 2 destiné à le. recevoir comme le montre la figure 3. Each housing 2, one of which is more particularly shown in broken lines in FIG. 3, is intended to receive a piece of solidified gas 3 whose volume is slightly less than the interior volume of the housing 2 intended for it. receive as shown in Figure 3.

Chaque bloc de gaz est par exemple de la glace carbonique sous forme de plaquettes ou ici de bâtonnets. Each block of gas is for example dry ice in the form of wafers or here sticks.

Chaque paroi 1 du conteneur est pourvue d'un rebord 5 (figures 1 et 3) destiné à recevoir par emboitement un couvercle 6 du type de celui de la figure 2. Each wall 1 of the container is provided with a rim 5 (FIGS. 1 and 3) intended to receive by interlocking a cover 6 of the type of that of FIG. 2.

Le couvercle 6 (figure 2) est également pourvu d'un rebord 7 destiné à venir recouvrir le rebord 5 et présente une forme adaptée pour obturer, en position de fermeture, les logements 2 du conteneur. The cover 6 (FIG. 2) is also provided with a rim 7 intended to come to cover the rim 5 and has a shape suitable for closing, in the closed position, the housings 2 of the container.

Comme le montre encore la figure 2, le couvercle 6 est aussi muni de logements tels que 8 destinés à recevoir des blocs de gaz solidifié, tandis qu'ils sont obturés lorsque le couvercle est mis en place, par le rebord 5 du conteneur. Les matériaux utilisés pour le couvercle 6 et pour les blocs à y insérer peuvent bien sûr être du même type que ceux utilisés pour le conteneur lui-même. As again shown in FIG. 2, the cover 6 is also provided with housings such as 8 intended to receive blocks of solidified gas, while they are closed when the cover is put in place, by the rim 5 of the container. The materials used for the cover 6 and for the blocks to be inserted therein can of course be of the same type as those used for the container itself.

La figure 4 montre un élément modulaire 9 muni aussi de logements 10 pour recevoir des blocs de gaz solidifié. FIG. 4 shows a modular element 9 also provided with housings 10 for receiving blocks of solidified gas.

Chaque élément modulaire 9 est destiné à venir dans l'espace libre du conteneur et de préférence contre la face interne de l'une de ses parois munie ou non de logements tels que 2. Each modular element 9 is intended to come into the free space of the container and preferably against the internal face of one of its walls, whether or not provided with housings such as 2.

En effet, l'épaisseur des parois 1, le positionnement des logements 2, le volume des blocs 3 sont divers paramètres importants selon les utilisations, de telle sorte que les éléments 9 permettent de jouer sur certains au moins de ces paramètres et d'adapter un conteneur pour une utilisation particulière. In fact, the thickness of the walls 1, the positioning of the housings 2, the volume of the blocks 3 are various important parameters depending on the uses, so that the elements 9 make it possible to play on at least some of these parameters and to adapt a container for a particular use.

L'utilisation est simple, mais les performances sont apparues tout à fait exceptionnelles et sans aucune mesure avec l'utilisation classique de morceaux de gaz solidifié disposés directement à l'intérieur d'un conteneur avec les produits euxmêmes.  The use is simple, but the performance appeared to be quite exceptional and without any measure with the conventional use of pieces of solidified gas placed directly inside a container with the products themselves.
