ES2283200A1 - Auto-warm packing device for packing of food, has lime and water are mixed together to produce heat and are able to utilize other chemical product, which is chloride of calcium and water - Google Patents

Abstract

The device has two joined pieces, in which primary piece accumulated the container of food and secondary is hermetically closed with a cover where they accumulated the lime and the water. The device is manufactured by plastic, which constitutes a closed system, in which two products exists either chemical product or other. The lime and the water are mixed together to produce heat and are able to utilize other chemical product, which is chloride of calcium and water.

Description

Device for self-heating containers of food.

Technical sector

We understand that the technical sector to which belongs this patent would be halfway between the mechanic and the chemical, since it is necessary to turn both parts of the device to so that the two products (water and quicklime) can be mixed and produce heat Therefore heat is produced through a chemical reaction, which has to be caused mechanically.

State of the art

Currently, within the devices intended for heating meals is not known to exist prior to device that you want to patent, none that do without need to previously remove the food from the container and without using An external source of heat. All ways to proceed to heating meals need an external heat source, either fire or any other that also needs to be connected to a power supply (microwave, ovens electric or gas ...) so that it can be used wherever there are no such energy sources (electricity, gas ...) either exist but cannot be used, or in case of not being able to light a fire or not be advisable (for example in the field or mountain in order to avoid forest fires).

Technical problem raised

On certain occasions the need arises for be able to heat food containers prepared for consumption, either in places where you cannot access heat sources or sources that can be accessed are not recommended (for example light a fire in the field) or the circumstances do not make it possible to use existing sources (in case of disasters that affect a large number of people who are that provide food that cannot be heated at the sources of usual heat, for example).

In this way, the device that is about patenting is capable of self-heating food containers, so that the use of fire or other source is not necessary for this of heat apart from the device itself, which is very advantageous when avoid, for example, the risk of fire if used in the countryside).

Technical advantage provided by the invention

The device is essentially a system closed in which there are two different chemicals and separated from each other, quicklime and water, which, alluding produce heat (CaO + H 2 O = Ca (OH) 2 + heat), although they could be used other products, such as calcium chloride and water, etc ... Parts material can be plastic or other suitable material to the use to which it is intended.

Description of the drawings

1.- First piece, intended to house the container of food

2.- Second piece, intended to accommodate tightly lime and water by a lid

3.- Machihembrado between the first and second pieces that allows a stable union of the same
more

4.- Part of the second piece that contains the Water

5.- Part of the second piece that contains the lime

6.- Machihembrado between the first and first pieces second that allows a stable union of the same

7.- Cover for sealing the piece second, which contains the liquids

8.- Accommodation located in the second piece intended to stack several units vertically.

Embodiment of the invention

The system is manufactured so that it consists of two pieces:

The first serves to house the food container (1) and, in turn, has two cones (2).

The second serves to accommodate the lime (5) and the water (4), which is tightly closed with a lid (7).

As for the operation, once assembled the pieces, according to the figure in this regard, rotate a piece on the Another in any way. In this way, the cones (2) of the first piece will break the container where the water is (4), which then mix with lime (5) and be produced in this way the heat needed to heat the container.

For a better use of heat, the First piece is hollow in the central part.

To stack several units vertically, in the second piece there is a housing (8) of the same diameter as the upper part of the container to be heated.

In order to maintain a stable union between two pieces, a tongue and groove is made between them (3) and (6).

Claims (1)

1. Device that allows food containers to be self-heated, without using any other external source of heat since it is capable of producing this heat by itself, and which is characterized in that it is made of plastic and consists of two pieces joined by a tongue and groove (3) to maintain a stable bond between them. The first piece (1) serves to house the food container and has two cones (2) and the second one is tightly closed by means of a lid (7), which serves to accommodate the water (4) in separate compartments and lime (5) (which will later be mixed to produce heat). The first piece is hollow in the central part for a better use of heat.
