Description

Conteneur dans lequel on peut libérer à un instant choisi des friαories ou des calories Container in which friαories or calories can be released at a selected time
La présente invention se rapporte aux conteneurs destinés à 5 emmagasiner des produits et, tout particulièrement, des denrées alimentaires tout en les maintenant à une température requise, soit froide, soit chaude.The present invention relates to containers intended for storing products and, in particular, foodstuffs while maintaining them at a required temperature, either cold or hot.
On connaît déjà par le US-A- 4 205 531 un conteneur comprenant un caisson à paroi thermiquement isolante et muni d'une porte et des moyens pour faire en sorte que la température à l'intérieur du caisson soit différente de I O celle à l'extérieur.US-A-4,205,531 already discloses a container comprising a box with a thermally insulating wall and provided with a door and means for ensuring that the temperature inside the box is different from IO that at l 'outside.
L'inconvénient de ces conteneurs est que l'entrée en action des moyens pour faire en sorte que la température à l'intérieur du caisson soit différente de celle à l'extérieur ne peut pas être retardée. Pour disposer d'un conteneur dont le contenu puisse être refroidi ou chauffé à un instant choisi 15 par l'utilisateur sans que, pendant la durée d'attente, des frigories ou des calories fournies par lesdits moyens ne soient consommées, on peut utiliser un réservoir de gaz communiquant par un conduit muni d'une vanne avec un récipient de réactif solide, le gaz et le réactif solide étant tels qu'ils réagissent suivant une réaction réversible exothermique dans un sens et endothermique o dans l'autre sens, l'un du réservoir et du récipient étant à l'intérieur du caisson et l'autre étant à l'extérieur comme décrit aux US-A-4 848 994,.4 944 159, 2 167 264 et 2 496 459 et au EP-A 521 148.The disadvantage of these containers is that the entry into action of the means to ensure that the temperature inside the box is different from that outside can not be delayed. To have a container whose contents can be cooled or heated at a time chosen by the user without, during the waiting time, frigories or calories supplied by said means being consumed, one can use a gas tank communicating through a pipe fitted with a valve with a solid reagent container, the gas and the solid reagent being such that they react in a reversible reaction exothermic in one direction and endothermic o in the other direction, the one of the tank and the container being inside the box and the other being outside as described in US-A-4,848,994, .4,944,159, 2,167,264 and 2,496,459 and in EP-A 521,148.
Lorsque l'utilisateur du conteneur veut le refroidir ou lorsqu'il veut en maintenir la température à une température plus froide que celle qui règne à 5 l'extérieur, il lui suffit d'ouvrir la vanne. Le gaz qui est notamment de l'ammoniac ou ses dérivés comme des alcoylamines en C1 à C8, notamment la monométhylamine, la diméthylamine, mais qui peut être également de l'eau, du CO2, du SO2, du SO3 ou de l'H2, réagit sur le réactif solide adsorbant qui peut être un sel tel qu'un halogénure, un pseudohalogénure, un carbone, un sulfate, un nitrate, un oxyde ou un nitrure métallique et qui, de préférence, est dans une matrice en graphite naturel expansé. L'endothermicité de la réaction donne le refroidissement souhaité. Comme métaux des sels constituants les réactifs solides, on peut utiliser notamment des sels de métaux alcalinoterreux, des sels de zinc, de manganèse, de fer et de nickel. On peut citer notamment comme sel MnCI2, SrCI2, SrBr2 pour maintenir la température à 3°C et NiCI2, MgCI2, MgBr2 et NiBr2 pour maintenir la température à -20°C. Le réservoir peut contenir aussi un second réactif solide moins avide du gaz que le premier réactif solide contenu dans le récipient.When the user of the container wants to cool it or when he wants to keep the temperature at a temperature colder than that which prevails outside, he need only open the valve. The gas which is in particular ammonia or its derivatives such as C 1 to C 8 alkylamines, in particular monomethylamine, dimethylamine, but which can also be water, CO 2 , SO 2 , SO 3 or H 2 , reacts on the solid adsorbent reagent which can be a salt such as a halide , a pseudohalide, a carbon, a sulphate, a nitrate, an oxide or a metal nitride and which, preferably, is in a matrix in expanded natural graphite. The endothermicity of the reaction gives the desired cooling. As the metals of the constituent salts of the solid reactants, it is possible in particular to use alkaline earth metal salts, zinc, manganese, iron and nickel salts. Mention may in particular be made, as salt MnCI 2 , SrCI 2 , SrBr 2 to maintain the temperature at 3 ° C. and NiCI 2 , MgCI 2 , MgBr 2 and NiBr 2 to maintain the temperature at -20 ° C. The reservoir may also contain a second solid reagent less greedy for gas than the first solid reagent contained in the container.
Tant que l'utilisateur n'a pas ouvert la vanne, il n'y a pas de réaction et la quantité potentielle de frigories ou de calories reste conservée. Mais il arrive que l'utilisateur oublie d'ouvrir ou de fermer la vanne et le conteneur ne fonctionne plus comme il le faudrait.As long as the user has not opened the valve, there is no reaction and the potential quantity of frigories or calories remains preserved. However, sometimes the user forgets to open or close the valve and the container no longer works as it should.
L'invention pallie cet inconvénient par un conteneur ne nécessitant de manoeuvrer la vanne et qui est donc plus sûr de fonctionnement.The invention overcomes this drawback by a container which does not require the valve to be operated and which is therefore safer to operate.
Suivant l'invention, la vanne est commandée par un dispositif actionné par le déplacement de la porte, étant entendu que par porte on entend également dans le présent mémoire un couvercle. Tant que la porte est, par exemple ouverte, les moyens destinés à faire sorte que la température à l'intérieur du caisson soit différente de celle à l'extérieur ne sont pas mis en fonctionnement et ce n'est que lorsque l'on ferme la porte, après avoir garni le conteneur de denrées alimentaires ou autres, que lesdits moyens entrent en action. De préférence, l'agencement est tel que la vanne ne peut s'ouvrir que lorsque la porte est fermée.According to the invention, the valve is controlled by a device actuated by the movement of the door, it being understood that by door is also understood in this specification a cover. As long as the door is, for example open, the means intended to ensure that the temperature inside the box is different from that outside is not put into operation and it is only when we close the door, after filling the container with foodstuffs or the like, that said means come into action. Preferably, the arrangement is such that the valve can only open when the door is closed.
On peut également prévoir une sonde de température disposée à l'intérieur du caisson et des moyens pour modifier l'état de la vanne lorsque la sonde repère une température donnée à l'avance. Les moyens, destinés à faire en sorte que la température à l'intérieur du caisson soit différente de celle à l'extérieur, n'entrent alors en action que lorsque la sonde de température a détecté une température inférieure à un seuil donné ou supérieure à un seuil donné. Pour régénérer le réactif adsorbant contenu dans le récipient, celui-ci est muni d'un dispositif de chauffage.It is also possible to provide a temperature probe placed inside the box and means for modifying the state of the valve when the probe locates a temperature given in advance. The means, intended to ensure that the temperature inside the box is different from that outside, then only come into action when the temperature sensor has detected a temperature below a given threshold or above a given threshold. To regenerate the adsorbent reagent contained in the container, it is provided with a heating device.
Suivant un mode de réalisation, le caisson est subdivisé en deux compartiments par une cloison thermiquement isolante, le réservoir étant placé dans l'un des compartiments et le récipient dans l'autre. On peut ainsi obtenir la production de frigories dans l'un des compartiments et de calories dans l'autre. Lorsqu'il y a deux compartiments, on considère, dans le présent mémoire, que l'un d'entre eux est au moins fonctionnellement en dehors du caisson, puisqu'il ne peut pas recevoir les mêmes produits que ceux qui sont emmagasinés dans l'autre compartiment, en raison des températures différentes qui vont régner dans les deux compartiments. Les deux compartiments peuvent notamment être l'un au-dessus de l'autre, le réservoir étant placé dans le compartiment supérieur puisque la chaleur a tendance à se propager vers le haut, alors que les frigories ont tendance à se propager vers le bas. Il vaut mieux placer la vanne dans le compartiment froid où se trouve le réservoir pour éviter qu'elle ne tombe en panne sous l'effet de la chaleur. De préférence, on met des réactifs solides de nature différente ayant une différence d'avidité pour le gaz. On peut utiliser les couples de sels NiCI2,According to one embodiment, the box is subdivided into two compartments by a thermally insulating partition, the tank being placed in one of the compartments and the container in the other. We can thus obtain the production of frigories in one of the compartments and calories in the other. When there are two compartments, it is considered, in the present specification, that one of them is at least functionally outside the box, since it cannot receive the same products as those which are stored in the 'other compartment, due to the different temperatures that will prevail in the two compartments. The two compartments can in particular be one above the other, the tank being placed in the upper compartment since the heat tends to propagate upwards, while the frigories tend to propagate downwards. It is better to place the valve in the cold compartment where the tank is located to prevent it from breaking down under the effect of heat. Preferably, solid reagents of different nature having a difference in avidity for the gas are used. We can use the NiCI 2 salt pairs,
MgCI2, MgBr2, NiBr2 pour un compartiment froid à 3°C et un compartiment à réchauffer à 65°C et NiCI2, NiBr2 pour un compartiment froid à -20°C et un compartiment à réchauffer à 65°C.MgCl 2, MgBr 2, NiBr 2 for a cold compartment at 3 ° C and a compartment to warm to 65 ° C and NICI 2, NiBr 2 in a cold chamber at -20 ° C and one compartment to warm to 65 ° C.
Aux dessins annexés, donnés uniquement à titre d'exemple : la figure 1 est une vue en coupe suivant un plan vertical d'un conteneur suivant l'invention, la figure 2 est une vue en coupe suivant la ligne ll-ll de la figure 1 , la figure 3 est une vue semblable à la figure 1 d'une variante, et la figure 4 est une vue semblable à la figure 1 d'une autre variante.In the accompanying drawings, given only by way of example: FIG. 1 is a sectional view along a vertical plane of a container according to the invention, FIG. 2 is a sectional view along the line ll-ll of the figure 1, Figure 3 is a view similar to Figure 1 of a variant, and Figure 4 is a view similar to Figure 1 of another variant.
Le conteneur représenté aux figures 1 et 2 comporte un caisson 1 en inox ou en poiyéthylène avec injection de polyuréthanne à l'intérieur, de manière à le rendre bien isolante de la chaleur. Ce conteneur est de forme parallélépipédique et comporte un fond 2 et un sommet 3. D'un côté, on peut accéder à l'intérieur du conteneur par une porte 4, la position ouverte de la porte étant représentée en trait mixte à la figure 2. Près du sommet 3 est fixé, à l'intérieur du conteneur 1 , un réservoir 5 d'ammoniac qui communique par un conduit 6 muni d'une vanne 7 avec un récipient 8 fixé entre les roues 9 du conteneur sous le fond 2. Le récipient de réactif solide contient du chlorure de calcium dans une matrice en graphite naturel expansé. On trouvera des exemples de préparation de produits de ce genre au brevet européen n° 129 473, au brevet européen n° 477 343, au brevet américain n° 5 283 219 et au brevet français n° 95 03614. Il est prévu dans le récipient 8 une résistance électrique 10 de chauffage pouvant être reliée au secteur par un conducteur 11. Comme le montre mieux la figure 2, la vanne 7 comporte un poussoir actionné par le déplacement de la porte 4. Lorsque la porte 4 est ouverte, elle vient pousser un poussoir 13 qui ouvre la vanne 7. Dès que la porte 4 revient en la position fermée, le poussoir 13 est repoussé par un ressort et la vanne reprend son état antérieur.The container shown in Figures 1 and 2 has a box 1 made of stainless steel or polyethylene with injection of polyurethane inside, so as to make it well insulating from heat. This container is of rectangular shape and has a bottom 2 and a top 3. On one side, one can access the interior of the container by a door 4, the open position of the door being shown in phantom in Figure 2 Near the top 3 is fixed, inside the container 1, an ammonia tank 5 which communicates by a conduit 6 provided with a valve 7 with a container 8 fixed between the wheels 9 of the container under the bottom 2. The solid reagent container contains calcium chloride in an expanded natural graphite matrix. Examples of the preparation of products of this kind can be found in European patent n ° 129,473, European patent n ° 477,343, American patent n ° 5,283,219 and French patent n ° 95,03614. It is provided in the container 8 an electrical heating resistor 10 which can be connected to the sector by a conductor 11. As best shown in FIG. 2, the valve 7 comprises a push-button actuated by the movement of the door 4. When the door 4 is open, it comes to push a pusher 13 which opens the valve 7. As soon as the door 4 returns to the closed position, the pusher 13 is pushed back by a spring and the valve returns to its previous state.
A la figure 3, où l'on a utilisé les mêmes numéros de références qu'à la figure 1 pour désigner les mêmes éléments, il est prévu une sonde 14 de température montée à l'intérieur du conteneur qui, lorsque la température s'abaisse en-dessous d'un seuil donné, envoie par un conducteur 15 un signal correspondant à un thermostat 16, lequel en étant alimenté par une batterie 17 envoie par des conducteurs 18 l'ordre à l'électrovanne 7 de s'ouvrir.In FIG. 3, where the same reference numbers have been used as in FIG. 1 to designate the same elements, there is provided a temperature probe 14 mounted inside the container which, when the temperature lowers below a given threshold, sends by a conductor 15 a signal corresponding to a thermostat 16, which by being supplied by a battery 17 sends by conductors 18 the order to the solenoid valve 7 to open.
A la figure 4, le caisson 1 a deux portes 4 et est subdivisé par une cloison 19 horizontale thermiquement isolante en un compartiment 20 supérieur chaud et en un compartiment 21 inférieur froid. Le réservoir 5 ainsi que la vanne 7 sont placés dans le compartiment 21 inférieur froid, tandis que le récipient 8 est placé dans le compartiment 20 supérieur chaud. In FIG. 4, the box 1 has two doors 4 and is subdivided by a thermally insulating horizontal partition 19 into a warm upper compartment 20 and into a cold lower compartment 21. The reservoir 5 and the valve 7 are placed in the cold lower compartment 21, while the container 8 is placed in the hot upper compartment 20.
