Description

Dispositif de chauffage intégré, en particulier pour barquettes alimentaires.Integrated heating device, in particular for food trays.
La présente invention concerne un dispositif de chauffage intégré, en particulier pour barquettes alimentaires, dans lequel le chauffage est assuré par une réaction exothermique.The present invention relates to an integrated heating device, in particular for food trays, in which the heating is provided by an exothermic reaction.
Certaines réactions sont accompagnées par un dégagement de chaleur important, accompagné dans certains cas par une émission de vapeur à haute température.Certain reactions are accompanied by a significant release of heat, accompanied in certain cases by an emission of steam at high temperature.
On a déjà proposé d'utiliser ce dégagement de chaleur pour chauffer différents produits, et en particulier des aliments.It has already been proposed to use this release of heat to heat various products, and in particular food.
La réalisation d'un dispositif techniquement et économiquement utilisable pose cependant des problèmes délicats, qui n'ont pu être résolus jusqu'à présent de manière pleinement satisfaisante.The production of a technically and economically usable device, however, poses delicate problems which have so far been unable to be fully satisfactorily resolved.
En particulier, le dispositif de chauffage prêt à l'emploi et contenant des réactifs appropriés doit pouvoir être stocké et manipulé sans que les réactifs se dégradent et sans que la réaction puisse se déclencher inopportunément, l'utilisation du dispositif doit être aussi simple que possible et son fonctionnement doit s'effectuer dans des conditions de sécurité absolue pour les usagers.In particular, the ready-to-use heating device containing suitable reagents must be capable of being stored and handled without the reagents degrading and without the reaction being able to start inopportune, the use of the device must be as simple as possible. and its operation must be carried out under conditions of absolute safety for users.
Le dispositif ne devant en principe servir qu'une seule fois, sa réalisation doit être aussi simple et peu coûteuse que possible.The device should in principle be used only once, its production must be as simple and inexpensive as possible.
La présente invention concerne un dispositif de chauffage intégré réunissant ces caractéristiques.The present invention relates to an integrated heating device combining these characteristics.
Le dispositif conforme à l'invention comprend essentiellement deux éléments superposés emboîtables par glissement l'un à l'intérieur de l'autre. Une charge d'un premier réactif est enfermée dans un compartiment étanche à la partie inférieure de l'élément supérieur. Une charge d'un second réactif est enfermée de manière étanche à la partie inférieure de l'élément inférieur. Les compartiments ou poches contenant les réactifs sont séparés par un organe adapté pour percer ou déchirer la paroi desdits compartiments ou poches lorsque l'usager enfonce l ' élément supérieur dans l'élément inférieur de sorte que le réactif contenu dans le compartiment supérieur puisse s'écouler dans le compartiment inférieur contenant l'autre réactif, déclenchant ainsi la réaction exothermique et le chauffage.The device according to the invention essentially comprises two superimposed elements which can be fitted together by sliding one inside the other. A charge of a first reagent is enclosed in a sealed compartment at the lower part of the upper element. A charge of a second reagent is sealed in the lower part of the lower element. The compartments or pockets containing the reagents are separated by a member suitable for piercing or tearing the wall of said compartments or pockets when the user pushes the upper element into the lower element so that the reagent contained in the upper compartment can flow into the lower compartment containing the other reagent, thereby triggering the exothermic reaction and heating.
Le chauffage est assuré sans que l'usager coure le moindre risque d'être brûlé, le dispositif restant parfaitement étanche pendant toute l'opération. Les caractéristiques et les avantages du dispositif selon l'invention apparaîtront plus complètement à la lecture de la description suivante de deux modes de réalisation particuliers de l'invention, donnés à titre d'exemples non limitatifs en se référant aux dessins annexés qui représentent : Figure 1, Vue générale d'un premier mode de réalisation de l'invention.Heating is ensured without the user running the slightest risk of being burned, the device remaining perfectly sealed during the entire operation. The characteristics and advantages of the device according to the invention will appear more fully on reading the following description of two particular embodiments of the invention, given by way of nonlimiting examples with reference to the appended drawings which represent: Figure 1, General view of a first embodiment of the invention.

Le dispositif représenté sur les figures 1 à 4 est de forme générale quadrangulaire et comporte deux éléments supérieur 10 et inférieur 12 reliés par une bande de sécurité détachable 14. L'élément supérieur 10 comporte un compartiment supérieur 16 adapté pour recevoir une barquette alimentaire 18 et fermé par un couvercle 20, et un compartiment inférieur 22 dans lequel est disposée une enveloppe 28 contenant enfermée hermétiquement une charge du premier réactif. Sur l'élément inférieur 12 vient s'emboîter la partie inférieure de l'élément supérieur pour venir buter contre les projections extérieures 30 de la paroi latérale 54. A l'intérieur de l'élément inférieur 12, une barquette étanche 34 contenant une charge du second réactif enfermée par un couvercle 35 est suspendue par les ailes 36 reposant sur les projections intérieures 32 de l'élément inférieur 12.The device shown in FIGS. 1 to 4 is of generally quadrangular shape and comprises two upper 10 and lower 12 elements connected by a detachable safety strip 14. The upper element 10 comprises an upper compartment 16 adapted to receive a food container 18 and closed by a cover 20, and a lower compartment 22 in which is disposed an envelope 28 containing hermetically sealed a charge of the first reagent. On the lower element 12 fits the lower part of the upper element to abut against the external projections 30 of the side wall 54. Inside the lower element 12, a sealed tray 34 containing a load of the second reagent enclosed by a cover 35 is suspended by the wings 36 resting on the internal projections 32 of the lower element 12.
Le fond 44 de l'élément supérieur 10 comporte quatre paires de fentes 46 coopérant par double encliquetage avec quatre paires de dents verticales 50, symétriques deux à deux et prévues sur la partie supérieure de la paroi latérale 54 de l'élément inférieur 12 Chacune des dents verticales50 possèdent un cliquet supérieur (52a) et un cliquet inférieur (52b) correspondant respectivement à la position de repos ou de transport et à la position de chauffage. L'organe d'ouverture des compartiments de réactifs est constitué par un croisillon 38 muni de lames 40 et garni de pointes 42 dirigées respectivement vers le bas et vers le haut. Ce croisillon est placé sous l'enveloppe 28 du premier réactif et au-dessus du couvercle 35 de la barquette 34. Aussi longtemps que la bande de sécurité détachable est maintenue en place, le dispositif peut être stocké et manipulé en toute sécurité, sans aucune possibilité de détérioration des réactifs, ni de déclenchement intempestif de la réaction, des réactifs étant maintenus séparés à l'intérieur de compartiments étanches. Après arrachement de la bande de sécurité 14, les éléments supérieur 10 et inférieur 12 sont maintenus solidaires. Les éléments 10 et 12 ne peuvent ainsi en aucun cas être séparés accidentellement ou à la suite d'une fausse manoeuvre.The bottom 44 of the upper element 10 comprises four pairs of slots 46 cooperating by double snap-fastening with four pairs of vertical teeth 50, symmetrical in pairs and provided on the upper part of the side wall 54 of the lower element 12 Each of the vertical teeth 50 have an upper pawl (52a) and a lower pawl (52b) corresponding respectively to the rest or transport position and to the heating position. The opening member of the reagent compartments is constituted by a spider 38 provided with blades 40 and furnished with spikes 42 directed respectively downwards and upwards. This spider is placed under the envelope 28 of the first reagent and above the cover 35 of the tray 34. As long as the detachable safety strip is held in place, the device can be stored and handled safely, without any possibility of deterioration of the reagents, or untimely triggering of the reaction, the reagents being kept separate inside sealed compartments. After tearing off the security strip 14, the upper 10 and lower 12 elements are held together. The elements 10 and 12 can in no case be separated accidentally or following a false maneuver.
La barquette alimentaire 18 contenant le plat à chauffer est disposée à l'intérieur du compartiment 16.The food tray 18 containing the dish to be heated is placed inside the compartment 16.
La barquette est munie d'ailes 64 fixées de manière étanche sur l'épaulement 66 de l'élément supérieur de sorte que la barquette soit suspendue à l'intérieur du compartiment 16. Le compartiment 16 est refermé par le couvercle amovible 20. Le consommateur arrache tout d'abord la bande de sécurité 14 et enfonce l'élément supérieur 10 sur l'élément inférieur 12. Dans ce mouvement, le croisillon est pris entre l'enveloppe 28 et le couvercle 35 de la barquette 34 et les pointes 42 déchirent l'enveloppe 28 alors que les lames 40 déchirent le couvercle 35 de la barquette 34. Le réactif contenu dans l'enveloppe 28 s'écoule alors dans la barquette 34 contenant le second réactif ce qui a pour effet de déclencher la réaction exothermique entre ces réactifs. La chaleur dégagée par la réaction est distribuée dans le compartiment 16 par des moyens de diffusion constitués d'ouvertures 48 ménagées sur tout ou partie du fond 44 de l'élément supérieur 10 pour venir chauffer la barquette 18. Une fois la réaction terminée, le consommateur retire le couvercle 20 et le plat chaud est prêt à être consommé.The tray is provided with wings 64 tightly fixed on the shoulder 66 of the upper element so that the tray is suspended inside the compartment 16. The compartment 16 is closed by the removable cover 20. The consumer first tears off the safety strip 14 and pushes the upper element 10 onto the lower element 12. In this movement, the spider is caught between the casing 28 and the cover 35 of the tray 34 and the tips 42 tear the envelope 28 while the blades 40 tear the lid 35 of the tray 34. The reagent contained in the envelope 28 then flows into the tray 34 containing the second reagent which has the effect of triggering the exothermic reaction between these reagents. The heat released by the reaction is distributed in the compartment 16 by diffusion means consisting of openings 48 formed on all or part of the bottom 44 of the upper element 10 to heat the tray 18. Once the reaction is complete, the consumer removes the cover 20 and the hot dish is ready to be eaten.
Les figures 7 et 8 représentent un autre mode de réalisation de l'invention dans lequel l'introduction de l'élément supérieur dans l'élément inférieur est réalisée par vissage d'un élément sur l'autre. Le dispositif de section générale circulaire, comprend deux cuvettes superposées 110 et 112 reliées par une bande de sécurité détachable 114.Figures 7 and 8 show another embodiment of the invention in which the introduction of the upper element into the lower element is carried out by screwing one element on the other. The device of circular general section comprises two superimposed bowls 110 and 112 connected by a detachable security strip 114.
La cuvette 110 comporte un compartiment supérieur 116 adapté pour recevoir une barquette, en particulier, une assiette ou un gobelet 118 et un compartiment inférieur 122 dans lequel est enfermée hermétiquement une charge d'un premier réactif. La cuvette 112 comporte un compartiment supérieur 128 dans lequel peut venir se visser la partie inférieure de la cuvette 110 jusqu'à venir buter sur la projection 130 séparant le compartiment supérieur 128 du compartiment inférieur 132 à l'intérieur duquel une barquette 134 refermée par un couvercle 135 et contenant enfermée hermétiquement une charge d'un second réactif est suspendue par les ailes 136 reposant sur les projections 130 de l'élément inférieur 112. L'organe d'ouverture des compartiments de réactifs est constitué par un croisillon 138 muni de lames garnies de pointes et dirigées vers le haut 140 et vers le bas 142 et disposé à l'intérieur du compartiment supérieur de la cuvette inférieure. La paroi 144 comporte à sa partie inférieure un pas de vis externe 150.The bowl 110 comprises an upper compartment 116 adapted to receive a tray, in particular, a plate or a cup 118 and a lower compartment 122 in which a charge of a first reagent is sealed. The bowl 112 has an upper compartment 128 into which the lower part of the bowl 110 can be screwed until it abuts on the projection 130 separating the upper compartment 128 from the lower compartment 132 inside which a tray 134 closed by a cover 135 and container hermetically sealed, a load of a second reagent is suspended by the wings 136 resting on the projections 130 of the lower element 112. The opening member of the reagent compartments is constituted by a spider 138 provided with blades furnished with points and directed upwards 140 and downwards 142 and arranged inside the upper compartment of the lower cuvette. The wall 144 has at its lower part an external screw pitch 150.
Une cuvette, assiette ou gobelet 118 contenant le plat ou la boisson à réchauffer est disposé à l'intérieur du compartiment 116 ; cette cuvette est munie d'ailes 164 qui viennent reposer sur l'êpaulement 166 de la cuvette supérieure 110 et sont fixées de manière étanche à celui-ci.A bowl, plate or cup 118 containing the dish or the drink to be heated is placed inside the compartment 116; this bowl is provided with wings 164 which come to rest on the shoulder 166 of the upper bowl 110 and are fixed in leaktight manner thereto.
La cuvette 118 est refermée par un couvercle amovible 120.The bowl 118 is closed by a removable cover 120.
Un pas de vis interne 152 coopérant avec le pas de vis 150 de la cuvette supérieure est prévue a la partie supérieure de la paroi 154 de la cuvette inférieure 112.An internal screw pitch 152 cooperating with the screw pitch 150 of the upper bowl is provided at the upper part of the wall 154 of the lower bowl 112.
Une feuille en matériau isolant 160 est disposée dans le fond de la cuvette 112 pour isoler le fond 162 de la chaleur dégagée dans l'appareil. Pour provoquer l'ouverture des compartiments contenant les réactifs et déclencher la réaction, l'utilisateur, après avoir arraché la bande de sécurité 114, visse l'élément supérieur 110 dans l'élément inférieur 112 ce qui provoque l'introduction de la partie inférieure de la cuvette supérieure dans la partie supérieure de la cuvette inférieure jusqu'à venir buter sur la projection 130, et l'ouverture des compartiments 122 et de la barquette 134 par les lames du croisillon 138.A sheet of insulating material 160 is placed in the bottom of the bowl 112 to isolate the bottom 162 from the heat given off in the device. To cause the opening of the compartments containing the reagents and to trigger the reaction, the user, after having torn off the security strip 114, screws the upper element 110 into the lower element 112 which causes the introduction of the lower part of the upper bowl in the upper part of the lower bowl until it comes up against the projection 130, and the opening of the compartments 122 and of the tray 134 by the blades of the spider 138.
Bien entendu, diverses modifications peuvent être apportées par l'homme de l'art aux dispositifs qui viennent d'être décrits à titre d'exemples non limitatifs, sans sortir du cadre de l'invention. Of course, various modifications can be made by those skilled in the art to the devices which have just been described by way of nonlimiting examples, without departing from the scope of the invention.
