Abstract

A cylindrical plastic container with a lid (2) and handle (5) contains a vessel (16) for carrying food and keeping it hot. The vessel is located within a water chamber which has two parts (14,15) made from copper and soldered together. The lower part (14) contains water and the upper part acts as a steam cylinder. An electrical element (20) supplied from electricity mains heats the water and steam rises to the steam cylinder and enters the food vessel (16). Condensed water re -enters the lower chamber (14) for recirculation via a valve (19). The water chamber is heavily insulated by asbestos plated polystyrene (10,11) and glass wool (12). Cutlery is carried in the handle (5).

Description

pour réchauffer la nourriture et la maintenir chaude quelques heures jusqu'au repas. I1 permet un assez long transport de la nourriture, épices et couverts rangés séparément.The present invention relates to a container

to reheat food and keep it warm for a few hours until mealtime. It allows a fairly long transport of food, spices and cutlery stored separately.

 The device is traditionally carried out by any container which maintains the temperature for a very short time.

This device according to the invention therefore makes it possible to eat the meal carried away, or hot picnics. It comprises according to the first characteristic
- a plastic cylindrical pot onto which a plastic cover is also screwed. These two are hermetically closed using a rubber seal. On the sides of the pot is fixed a handle in the form of a small hollow cylinder with a lid which is used to store the cutlery. The cylindrical pot is lined inside with polystyrene on which spreads an asbestos sheet lined with a layer of glass wool. This keeps the hot temperature inside the device. These materials surround an electric water balloon, the upper part of which has a steam cylinder in the form of a bowl which contains the food container hermetically closed by a lid by means of a seal, situated in the lid. The lower part has a water tank supplied by a closed orifice with a plug on the left. On the right is a resistance accompanied by a thermostat, these two making it possible to heat the water in the tank.

 Between the bowl and the tank is formed a small valve hole which is used to make the water flow from the bowl into the tank and prevents the water from rising from the latter through the hole.

The accompanying drawings illustrate the invention
FIG. 1 shows the device of the invention and the elements of the external part.

 FIG. 2 shows in section a variant of this device.

 Figure I shows a cylindrical pot (1) of rigid plastic which is closed by a cover (2) using a seal (3). In the cover (2) is formed a small hollow cylinder closed by another cover (4). On the right side of the cylindrical pot (1) is fixed a handle (5) in the form of a hollow cylinder inside. This handle is also closed by a cover (6) and a seal (7). At the bottom of the device on the right is an electrical outlet (8) connected to a bulb (9), a sort of thermostat indicator light. On the left side a plug (10) closes the opening of the balloon.

The drawing Il of the device presents in section
-the cylindrical pot (1) which is lined inside a layer of polystyrene (11) on which spreads an asbestos sheet (12) lined with a layer of glass wool (13). The whole enveloping a balloon (14) of water which is formed of two parts
-The upper part has a hollow steam cylinder (15), the shape of a bowl on which a food container (16) is placed, which is closed by a small hollow cylinder (17) and a seal (18) located in the cover ( 2).

 Between the bowl and the flask in the middle is a small valve hole (19).

 - The lower part has on the left a hole in the balloon which is closed by a plug (10). To the right is a resistor (20) connected to a thermostat (21) which heats the water in the tank.

Claims (6)

 1) Electric device for heating food, characterized in that it comprises a cylindrical container (1) consisting of a rigid plastic pot with a cover (2) with very rigid plastic screw and a tight seal (3).  2) Device according to claim jÇ characterized in that the container (1) has on the side a handle (5) in the form of a hollow cylinder for storing the cutlery, closed by a cover (6) and a seal (7) of rubber .  3) Device according to claim 2, characterized in that the cylinder (1) is lined inside, with a layer of polystyrene (11) 2 mm thick on which spreads a layer of asbestos ( 12) which is also lined with a 2 mm layer of glass wool (13).  4) Device according to claim 5 characterized in that the two parts of the balloon (14) and (15) are made of copper, welded to one another.  5) Device according to claim 4 characterized in that the container (16) is produced inside a thickness of 1 mm of very smooth aluminum and outside is fixed a layer of thickness 1 mm d granulated aluminum.  6) Device according to one of the preceding claims characterized in that the balloon (14) is supplied with water through an orifice closed by the plug (10). This water is heated by an electrical connection (8) using a resistor (20) up to 90 "c thanks to an integrated thermostat (21) which regulates the temperature. The hot water turns into steam which passes through the steam cylinder (15) which directs it through the small holes in the cylinder in the bowl. These water vapors circumnavigate the container (16) which in turn by its granular character recovers the heat of the vapors to reheat food. Vapors condense and flow to the bottom of the bowl. Water, the result of condensed vapors, passes through the valve hole (19), flows into the balloon (14) and circulates in a closed circuit.
