La invención objeto de esta memoria descriptiva funciona al estar la cápsula contenedora del liquido criogénico u otros a una temperatura muy por debajo de cero, por ejemplo: el nitrógeno licúa a -196 °C y el argón a - 185,9 °C, introduciéndose dicha cápsula dentro del dispositivo refigerador y regulándose a través del aislante y de los refrigerantes y los conductos de unión con la embocadura la temperatura que emite hacia el exterior, enfriando el recipiente ajustándose a las necesidades del refrigerador, según éste sea un vaso, nevera, cubitera, etc. de forma que consigue enfriar, refrigerar o congelar cualquier alimento o bebida. The invention object of this specification works to be the capsule containing the cryogenic liquid or others at a temperature well below zero, for example: nitrogen liquefies at -196 ° C and the argon at -185.9 ° C, said capsule being introduced inside the refueling device and regulating through the insulator and the refrigerants and the connecting conduits with the embouchure the temperature that it emits towards the outside, cooling the container adjusting to the needs of the refrigerator, depending on whether it is a glass, refrigerator, ice bucket, etc. so that it gets to cool, refrigerate or freeze any food or drink.
Además de estos elementos previamente descritos, es necesario un aparato cuya utilidad es la de "recargar" el frió de los productos, ya sea a través de válvulas o directamente pulverizando sobre la cápsula contenedora del líquido criogénico u otros. Este aparato estaría formado por una botella de gas o líquido criogénico u otros, con una "pistola de presión". Se introduce el producto dentro de aparato, y éste desmonta el producto y pulveriza sobre la cápsula criogénica u otros, o introduce e! líquido o gas a través de una válvula. Una vez "recargado" el producto, el aparato vuelve a cerrar la carcasa y ya vuelve a estar listo para ser utilizado.  In addition to these elements previously described, an apparatus is needed whose utility is to "recharge" the cold of the products, either through valves or directly by spraying on the capsule containing the cryogenic liquid or others. This apparatus would be formed by a bottle of gas or cryogenic liquid or others, with a "pressure gun". The product is introduced into the apparatus, and the latter disassembles the product and sprays on the cryogenic or other capsule, or introduces e! liquid or gas through a valve. Once the product is "recharged", the device closes the casing again and is ready to be used again.
Poco a poco, el recipiente va perdiendo sus propiedades refrigerantes y necesita ser "recargado" para recuperar sus funciones de refrigeración. Para esto, la carcasa de la invención se desmonta a través de una rosca, quedando expuesto el contenedor criogénico, para así pulverizar o inyectar más líquido sobre o dentro de la cápsula para que vuelva a recuperar sus funciones. Este aparato sirve para recargar cualquier producto que conlleve esta invención. Ventajosamente esta novedosa invención aporta al estado de la técnica un producto que enfría o mantiene fríos, refrigerados o congelados bebidas o alimentos sin necesidad de una fuente de alimentación externa como por ejemplo la electricidad, ni de hielo o nieve como las antiguas neveras y conservando, en todo momento, sus propiedades y cualidades refrigerantes. Little by little, the container loses its cooling properties and needs to be "recharged" to recover its cooling functions. For this, the housing of the invention is disassembled through a thread, the cryogenic container being exposed, so as to spray or inject more liquid on or into the capsule so that it returns to recover its functions. This apparatus serves to recharge any product that this invention entails. Advantageously this novel invention contributes to the state of the art a product that cools or keeps cold, refrigerated or frozen drinks or food without the need of an external power supply such as electricity, ice or snow like old refrigerators and conserving, at all times, its properties and cooling qualities.

Dentro de dicho material aislante se encuentra una cápsula contenedora de uno de los siguientes líquidos o gases criogénicos: nitrógeno líquido, argón líquido u oxígeno líquido, dióxido de carbono sólido, nieve carbónica, propano, helio líquido u otros gases, líquidos o sólidos, dependiendo del tiempo y de la utilidad que se le dé al dispositivo, pudiendo ser la de transportar alimentos en cadena de frío o la de mantenerlos fríos durante más tiempo. El material de dicho dispositivo puede ser aluminio, acero inoxidable, cobre o una aleación de metales con buenas propiedades termo conductoras y el revestimiento aislante de la cápsula contenedora de líquido criogénico puede ser poliestireno expandido o alguna otra espuma aislante de similares características, o también caucho o aire. En una realización diferente el aislante utilizado se sustituye por una cámara de gas o de líquido. The food-cooling device object of the present invention is constituted from a device that cools or keeps refrigerated or frozen foods inside it, being able to have the shape of bottle, cylinder, ice bucket, bucket or refrigerator, being in any case coated with an outer casing and in the middle an insulating material as a sandwich. Inside said insulating material is a capsule containing one of the following cryogenic liquids or gases: liquid nitrogen, liquid argon or liquid oxygen, solid carbon dioxide, dry ice, propane, liquid helium or other gases, liquids or solids, depending of the time and of the utility that is given to the device, being able to be the one to transport foods in chain of cold or to keep them cold during more time. The material of said The device can be aluminum, stainless steel, copper or an alloy of metals with good thermal conductive properties and the insulating coating of the cryogenic liquid containing capsule can be expanded polystyrene or some other insulating foam of similar characteristics, or also rubber or air. In a different embodiment the insulator used is replaced by a gas or liquid chamber.
El dispositivo presenta una embocadura que en el caso de tener forma de botella es un gollete que se tapona con un tapón, en caso de tener forma de vaso una abertura superior que se cierra con una tapa aislante y en el caso de nevera bien una abertura superior que se cierra con tapa o una puerta aislantes.  The device has a mouthpiece which, in the case of having the shape of a bottle, is a neck that is plugged with a stopper, in the case of a vessel shape, an upper opening that is closed with an insulating cover and in the case of a refrigerator or an opening top that closes with lid or insulated door.
De la cápsula sale al exterior una válvula para recargar el líquido o gas criogénico.  From the capsule, a valve goes out to recharge the liquid or cryogenic gas.
Además de estos elementos previamente descritos, es necesario un aparato cuya utilidad es la de "recargar" el frió de los productos, ya sea a través de válvulas o directamente pulverizando sobre la cápsula contenedora del líquido criogénico u otros. Este aparato estaría formado por una botella de gas o líquido criogénico u otros, con una "pistola de presión". Se introduce el producto dentro de aparato, y éste desmonta el producto y pulveriza sobre la cápsula criogénica u otros, o introduce el líquido o gas a través de una válvula. Una vez "recargado" el producto, el aparato vuelve a cerrar la carcasa y ya vuelve a estar listo para ser utilizado. Poco a poco, el recipiente va perdiendo sus propiedades refrigerantes y necesita ser "recargado" para recuperar sus funciones de refrigeración. Para esto, ia carcasa de la invención se desmonta a través de una rosca, quedando expuesto el contenedor criogénico, para así pulverizar o inyectar más líquido sobre o dentro de la cápsula para que vuelva a recuperar sus funciones. Este aparato sirve para recargar cualquier producto que conlleve esta invención. In addition to these elements previously described, an apparatus is needed whose utility is to "recharge" the cold of the products, either through valves or directly by spraying on the capsule containing the cryogenic liquid or others. This apparatus would be formed by a bottle of gas or cryogenic liquid or others, with a "pressure gun". The product is introduced into the apparatus, and the latter dismantles the product and sprays on the cryogenic or other capsule, or introduces the liquid or gas through a valve. Once the product is "recharged", the device closes the casing again and is ready to be used again. Little by little, the container loses its cooling properties and needs to be "recharged" to recover its cooling functions. For this, the housing of the invention is disassembled through a thread, the cryogenic container being exposed, so as to spray or inject more liquid on or into the capsule so that it returns to recover its functions. This apparatus serves to recharge any product that this invention entails.
La invención objeto de esta memoria descriptiva funciona al estar la cápsula contenedora de! líquido criogénico a una temperatura muy por debajo de cero, por ejemplo: el nitrógeno licúa a -196 °C y el argón a - 185,9 °C, introduciéndose dicha cápsula dentro det dispositivo refigerador y regulándose a través del aislante la temperatura que emite hacia el exterior, enfriando el recipiente ajustándose a las necesidades del refrigerador, según éste sea un vaso, nevera o cubitera, de forma que consigue enfriar, refrigerar o congelar cualquier alimento o bebida.  The invention object of this specification works to be the capsule containing! cryogenic liquid at a temperature well below zero, for example: nitrogen liquefies at -196 ° C and argon at -185.9 ° C, said capsule being introduced into the refracting device and regulating through the insulator the temperature that emits towards the outside, cooling the container adjusting to the needs of the refrigerator, depending on whether it is a glass, refrigerator or ice bucket, so that it gets to cool, refrigerate or freeze any food or drink.
