Abstract

The device according to the invention makes it possible to heat the edible content of a metal container without relying on a means of heating external to the metal container, in particular a tin of food preserve. It consists of sulphuric acid 1 insulated from quicklime 2 in an enclosure made of elastic plastic under air pressure 3 which additionally contains a heavy ball 4 in order that, when the receptacle 5 is shaken, the weight of the ball drives the plastic enclosure against one of the points 6 situated on the walls and the bottom of the receptacle 5 and under the bottom of the wall 7 in order to burst the plastic enclosure which will release the sulphuric acid 1 to come into contact with the quicklime 2. Owing to its ultrainstantaneous fusion, considerable heat will be released, which will make it possible to heat the edible content situated in the receptacle 9.

Description

La presente invention conserne "le procede auto-chauffant d'un recipient metallique par fusion ultra-instantanee" qui permet ainsi d'en rechauffer son contenu en un temps tres courts
Dans descsystemes connus de se genre, il y a la chaux vive qui en contact avec l'acide acétique (vinaigre blanc a' dix degres) degage de la chaleur afin de rechauffer le contenu du recipient.e procede encore plus performant que Liteau + chaux vive ne debute qu'à partir dectrentes segondes, la chaleur ma- xima3e est atteinte en deux minutes par fusion de la chaux,ce- tte chaleur persiste pendant dix minutes pour enfin regresser;;
lz recipient auto-chauffant par fusion ultra-instantanee selon l'invention permet la disparition d'un temps de reactio- n (trentes segondes) à partir du moment ou la chaux vive est en contact avec le liquide propose ici, pour atteindre une chaleur baucoup alus importante en une dure e de temps tres redite et dont son temps de vie (chaleur) sera plus long, tout ceci , par Apport au procede precedant.The present invention relates to "the self-heating process of a metal container by ultra-instantaneous fusion" which thus makes it possible to reheat its content in a very short time.
In known systems of this kind, there is quicklime which in contact with acetic acid (white vinegar at ten degrees) releases heat in order to warm the contents of the container. This process is even more efficient than Liteau + lime quick begins only from several seconds, the maximum heat is reached in two minutes by melting lime, this heat persists for ten minutes to finally regress;
lz self-heating container by ultra-instantaneous fusion according to the invention allows the disappearance of a reaction time (thirty seconds) from the moment when quicklime is in contact with the liquid proposed here, to reach a heat a lot of alus important in a very short time and whose life time (heat) will be longer, all this, by contribution to the previous process.

four obtenir un tel resultat de fusion ultra-instantanee il suffit de mettre en contact aves de la chaux vive de l'acl- de sulfurique, à partir de ce moment là, la reaction est ultra -instantanee, il n'y a aucune duree de temps de reaction pour que la chaleur naisse, la chaux vive est instantanement portee en fusion, la chaleur maximale se fait entre cinq et dix segondes, elle dure baucoup plus de dix minutes et en degre la chaleur est tres importante
Le dispositif selon l'invention permet donc d'isoler l'acide sulfurique (1)de la chaux vive (2) dans une enceinte en plastque elastique sous pression (3) qui elle contient en plus de l'acide sulfurique une bille lourde (4) afin que lorsque l'on secouera le recipient (5) la bille lourde par son poid entrainera l'enceinte en plastique elastique sous pression contre une des pointes (6) situee sur les parois et le iond du recipient (5) arin d'eclater l'enceinte en plastique qui liberera l'acide sulfurique (1) pour rentrer en contact.... furnace to obtain such a result of ultra-instantaneous fusion it is enough to put in contact with quicklime sulfuric acid, from this moment there, the reaction is ultra-instantaneous, there is no duration reaction time for heat to build up, quicklime is instantly melted, maximum heat is between five and ten seconds, it lasts a lot more than ten minutes and the heat is very high
The device according to the invention therefore makes it possible to isolate sulfuric acid (1) from quicklime (2) in an enclosure made of elastic pressure plastic (3) which, in addition to sulfuric acid, contains a heavy ball ( 4) so that when the container (5) is shaken the heavy ball by its weight will cause the elastic plastic enclosure under pressure against one of the points (6) located on the walls and the ion of the container (5) arin d explode the plastic enclosure which will release sulfuric acid (1) to come into contact ....

avec la chaux vive (2) situee à la base du recipient (5) celui-ci permet la double paroi (7) et (8) pour que la chaleur puisse se propager en haut du recipient afin d'une efficacite plus grande de l'utilisation optimale de la chaleur, qui elle est ghargee de échauffer le contenu consommable situe en (9). with quicklime (2) located at the base of the container (5) it allows the double wall (7) and (8) so that the heat can propagate at the top of the container in order to increase the efficiency of the optimal use of heat, which is responsible for heating the consumable content located in (9).

bA partie chauffante est totalement isolee de la partie chauffee (9) il y a juste transmission de chaleur d'un point à un autre et egalement isolation de la partie chauffante et de l'environement exterieur immediat du recipient, c'est à dire qu'un individu qui aura dans ces romains le recipient ne sera pas en contact avec le procede auto-chauffant du recipient il sentira seulement la chaleur donc aucun risque quelconque. bA heating part is completely isolated from the heated part (9) there is just transmission of heat from one point to another and also insulation of the heating part and the immediate external environment of the container, i.e. 'an individual who will have in these Romans the container will not be in contact with the self-heating process of the container he will feel only the heat therefore no risk whatsoever.

Le procede auto-chauffant d'un recipient metallique par fusion ultra-instantanee peut recevoir une application industrielle en raison de son interet pratique, dans le but de la fabrication de boite de conserve alimentaire auto-chauffante par fusion ultra-instantanee de la chaux vive, dans le soucis en plus du -gain de temps certain, d'offrir un service supplementaire aux consoininateur divers. The self-heating process of a metal container by ultra-instantaneous fusion can receive an industrial application because of its practical interest, for the purpose of manufacturing a self-heating food can by ultra-instantaneous fusion of quicklime. , in order to save time, to offer an additional service to various consoininator.

Claims

1) self-heating device of a metal container characterized in that it comprises sulfuric acid (1) with a heavy ball (4) all located in an elastic plastic enclosure under air pressure (v) , quicklime (2) located at the base of the container (5) which when shaken will allow the ball by its weight to enter the plastic enclosure towards one of the points (6) so as to burst this enclosure (3) which will thus release the sulfuric ACI6 so that it can come into contact with quicklime which it will start to merge to give off heat
