Abstract

The present invention relates to a can-heating device solely for all liquid products. The self-heating method of the can (5) comprises a first part (B), containing a glass enclosure (3) in which the reactive liquid (1) is located, whose glass enclosure (3) is located inside the base of the bottom of the lid (10) of the can heater (5) and locked by its ends to the base of the wall (11) of the can (5), which will allow the user casually to strike the wall (12) of the can (5) in order to shatter the glass enclosure (3) instantly, which releases the reactive liquid (1) in order to come back into contact with the second reactive, pure lime in grains (2), located above the glass enclosure (3) and thus to start the exothermic reaction by ultra-instantaneous fusion, and the intense heat released is transmitted through the wall (4) to the liquid product contained in the can (6), thus ensuring that it boils in a few seconds provided that it is solely a liquid product. The type of packaging of the can (6), made of aluminium or metal, thus makes it possible to provide a can (6) whose contents of a liquid product (such as liquid coffee, cacoa-flavoured milk or coffee-flavoured milk, but anything is possible such as tea, liquid soup etc...) are greater in comparison with 25 cl or 33 cl or 50 cl cans. The can (6) is provided with a lid (14) with a pull tab (9) thus allowing the user to open or remove the pull tab (9), located on the lid (14).

Description

 The present invention relates to a device for a tin can heater only for all liquid products.

 There are currently many self-heating canned food cans, but these are not very reliable.

 Generally the problem of airtight packaging remains for some self-heating cans, at the same time as the intense heat given off in vapor during the exothermic reaction inside some self-heating cans, which characterizes that this steam s '' escapes due to one or more openings which allow emission of excess vapor emission, and on the other hand the excessive calorie loss, which characterizes that a quantity of vapor escapes and can be a nuisance for the user in relation to the release of excess vapor emission from the orifices.

 The invention proposed here avoids it is inconvenient, as long as the packaging of the canned can heater, contains the reagents is hermetically sealed, and thus allows to boil the liquid product located in the canned can, without see a steam emission release gene, due to the fact that the can heater is rigorously and hermetically sealed.

The can heater of the can according to the invention is composed of a can (6), and of its can (5), being separated by a wall (4) which constitutes the inner bottom (7) of the tin can
(6), and the other face of the wall (4) thus ensuring the acting bottom (8) of the box (5), where there is a glass enclosure (3) containing a reactive liquid (1), and a second solid reagent (2) located above the glass enclosure (3), and characterized by the fact that the can (6) the wall which constitutes the bottom (4) and the can
(5) its effect in a single molding or other operation of the part (6), (4) and (5), thus ensuring the hermetically sealed separation of the liquid product located in the can (6), and of the process self-heating located in the box (5).

 The self-heating process located in the box (5) is composed of a first part (B), containing a glass enclosure (3), where the reactive liquid (l), which may be water, is located there. or sparkling water or mineralized water, or hydrogen peroxide, or citric acid, or ten degree white vinegar, of which the glass enclosure (3) is located inside from the base of the bottom of the cover (10) of the box (5), the glass enclosure (3) of cylindrical or other shape is blocked by these ends at the wall (li) of the box (5), which will allow the user to give a simple hit - fortuitously to the wall (12) of the box (5), in order to instantly burst the glass enclosure (3), which releases the reactive liquid (1), in order to come into contact with the second solid reagent (2), which can be lime oxide, or calcium hydrate, or calcium oxide, or potassium hydroxide, or pure lime in grains, o u fatty lime, and thus trigger the exothermic reaction by ultra-instantaneous fusion, and the intense heat released in vapor is transmitted through the wall (4) to the liquid product located in the can (6), thus ensuring its boiling if it is only a liquid product.

The packaging of the box (5), relative to the wall (4), and the cover (10), may have the particular application of resisting excess vapor emission, during the exothermic reaction of the reactants (1) and (2), since a quantity of two volumes of pure lime in grains (2), and that a quantity of 15 ml of reactive liquid contains only water (1), or three volumes of pure lime in grains (2), for 20 ml of water (1), is enough to bring to boiling the liquid product located in the can (6), than to can of canned album ~ Inium, or metallic, and without deterioration occurring in the box
(5), and thus allow to have a self-heating tin can, without seeing a steam emission release gene due to the exothermic reaction of the reactants (1) and (2), and therefore that the packaging of the box (5 i relative to the cover (10), and to the wall
(4), may have the particular application of resisting the excess of vapor emission of the reactants (1) and (2), and because of the quantity of the reactants proposed here is sufficient to produce a release of heat sufficient, but not excessive for the packaging of the box (5), of the cover (10) in relation to the fixing by crimping of the cover (10) in relation to the box (5), and of the wall (4), and brought to a boil in a few seconds the liquid product located in the can (6) due to the wall (4).

 The first part * the box (3), is provided with a cover (10) + without tongue, and located at the base of the box (5), in view of rigorously and hermetically isolating the glass enclosure (3 ) containing the reagent liquid (I), and the second reagent (2), due to the wall (4), and due to the fixing of the cover (10) relative to the box (5), by crimping the cover (10).

 The second part of the can (Â), is provided with a cover (14) with tongue (9), located at the base of the can C 6), the cover (14) of which is fixed to report of the can (6), by crimping the cover (14), thus ensuring the hermetically sealed preservation of the liquid product, and thus allowing the user to open or to decapsulate the tab (9) which is located on the cover t 14) *

Claims (3)

CLAIM  1) The self-heating process of the box (5), is composed of a first part (B), containing a glass enclosure (3), where the reactive liquid (1) is introduced, which can be of water, or carbonated water, or mineralized water, or hydrogen peroxide, or citric acid, or white vinegar at ten degrees, before coming into contact with the reactive densfléme (2) , which may be lime oxide, or calcium hydrate, or calcium oxide, or potassium hydroxide, or pure grain lime, or fatty lime.  2) The self-heating process of the box (5) according to claim I), including a glass enclosure (3), is located inside the base of the bottom of the cover (10) of the box (5) , is blocked by its extremiter at the base of the wall (11) of the box (5).  3) The self-heating process of the box (5), according to claim 1) and 2), characterized by the fact that will allow; the user to give a simple fortuitous blow to the wall t 12) of the box (5), in order to burst the glass enclosure (3) instantly, which releases the reactive liquid (I), in order to come into contact with the second reagent t 2), located above the glass enclosure (3), and thus trigger the exothermic reaction by ultra-instantaneous fusion, and the intense heat released is transmitted through the wall (4), to the product liquid located in the can (6).
