The device consists of thermal module 1 and two snap-on covers 2 and 3, cover 2 with a latch 4 is installed in the lower part of the thermal module, cover 3 is installed in the upper part of the container body and is a removable, locking mechanism, which is an internal lock 5 installed in the upper, the inside of the thermal module 1, the outer lock 6 mounted on the outside of the thermal module 1 from the outside of the safety ring 7.

The inner lock 5 consists of a welded ring 8 with a hole 9 for the valve, which is welded onto an aluminum-plastic cup 10 with the liquid product for heating in it, an inlet element made in the form of an inlet valve 11 for air supply, a safety ring 7 with a lock 12 for the push-button rubber button 20 to exclude the possibility of its displacement to the side and latch 13 on the welded ring.

The external lock 6 consists of a series of teeth 14, one row of which is directed in one direction, the other row of teeth is directed in the opposite direction.

In the inner part of the inlet valve 11, a vertical hole 15 and a horizontal inlet 16 for supplying air to a container 17 (tank) installed in the lower part of the inlet valve are made, in its upper part there is a groove 18 with an annular latch 19 for fixing the rubber pressure valve on the inlet valve buttons 20, and for fixing the intake valve 11 in the lowered position, a retaining ring 21 is installed.

On the underside of the removable and snap-on lid 3 of the container, a groove 22 is made in which a latch 23 is mounted for fixing the removable snap-on lid 3 on the container.

Three safety valves 24 are installed on the thermal module 1 on its snap-on cover 2, which are made in the form of grooves concave into the inside of the thermal module 1 along its circumference, in the grooves of the safety valves 24 in the upper part of the thermal module and in the lower part of its snap-on cover 2, are made in the vertical the direction through holes of the same shape 25 for the release of warm air and steam, coaxial to these holes on the side of the lid of the thermal module 1 and on the side of the housing 26, have one common through opening article 27 for the exit of warm air from the container, at the bottom of thermal module 1 there is an additional hole 28 with a sealed plug 29 for filling the reagent.

To remove the removable, snap-on lid 3 from the container there is a ring 30.

The assembly of the container is as follows.

A safety ring 7 is installed on the aluminum-plastic cup 10 with the welded ring 8 and closed with a latch 13 and a latch 12. The tank (tank) 17 is filled with liquid reagent and an inlet valve 11 is installed through its lower part, then through the lower part of the aluminum-plastic cup 10 set the filled tank 17, attach it to the top of the glass.

The inlet valve 11 is passed through an opening 9 in the welded ring 8, a push-button rubber button 20 is fixed on top of the valve, fixed with an annular latch 19 to prevent spontaneous lowering of the inlet valve downward, while the inner part of the push-button rubber 20 fits tightly around the annular latch 19, which fixes this rubber button in a predetermined position, and the inlet valve 11 is fixed in the lowered position by the retaining ring 21.

Then, the aluminum-plastic cup 10 together with the tank 17 is lowered into the thermal module 1 until it stops and snap it in the set position by means of the locking mechanism, fixing the glass 10 in the desired position, while both rows of teeth 14 of the locking mechanism are engaged with each other, located inside thermocasing 26, firmly and firmly hold the container body in assembled form.

Then, through an additional hole 28 at the bottom of the thermal module 1, the dry reagent is poured into the thermal module and hermetically close this hole with a stopper 29, while the lower part of the thermal module 1 is closed with a snap-on lid 2 with the sorbent filter inside it.

The seasoned thermal module 1 is inserted into a hermetically sealed, without gaps, thermocasing 26 so that the through hole on the lid of the thermomodule coincides with the hole in the lower part of the thermowell and forms one through hole 27.

The lid 3 is lowered onto the container and closed tightly onto the assembly thus assembled together with the thermo-housing 26 by means of ring 30, and when the lid is lowered onto the container, a latch 23 is used, and when the lid is removed from the container, the ring 30 is used.

The container works as follows.

When you press the rubber pushbutton 20 to the stop, the retaining ring 21 passes through the hole 9 in the welded ring 8 and, having straightened in its lower part, hermetically closes the hole, eliminating the return of the inlet valve 11 to its original position. Through the inner hollow part of the inlet valve, air is supplied to the container 17 through a horizontal inlet 16 in the upper part of the valve. When the push-button rubber button 20 is pressed, the valve opening is inside the container, while the liquid reagent starts to flow uniformly from the container 17 through the outer part of the open intake valve 11, and air enters the inner hollow part of the intake valve, and the resulting vapor gradually pushes the liquid reagent out of the container , while the vapor under pressure exits through the safety valves 24 through its grooves, enters the lower part of the thermal module 1 under the snap-on lid 2, in which there is a filter sorbent. The liquid reagent is rapidly mixed with the sorbent filter and they are heated, and the two reagents are heated very quickly, within 1-3 minutes, after which time the temperature is still maintained for up to 10 minutes.

After pressing the rubber push button 20, the lock ring 19 of the inlet valve 11 is actuated and, through its horizontal inlet 16, the container 17 with the liquid reagent drops down, while the inlet valve leaves the seat and an open space for the exit of the liquid reagent forms around the bottom of the tank . The air remaining in the thermal module rises through the vertical hole 15 in the inlet valve 11 and exits through the horizontal inlet 16, thereby dispensing the liquid reagent in the container into the thermal module 1 with the dry reagent in it. After the start of the exothermic reaction, excessive pressure, which could affect the change in the rate of liquid reagent, exits through the through hole 25 through the grooves of the safety valves 24 and enters the lower part of the cover 2 of the thermal module, where the filter sorbent is located. Since the through holes 25 and the common through hole 27 between the thermal module and the thermal jacket on the thermal module cover and on the thermal jacket are located in the same vertical direction and aligned with each other, air and steam first pass through the hole 25 into the thermal module cover 2, and then through the hole 27 sorbent air leaves the container body to the outside. Thus, a quick heating of the food product occurs in the container by mixing two chemical reagents: liquid and solid, located on the outside of the aluminum-plastic cup 10 in thermal module 1.

The finished product is convenient to use, since it does not require additional transfusion or transfer to another container, and the container can be used either with the finished food product or with a semi-finished product, such as tea, coffee, etc.

The presence of a locking mechanism in the container with opposite rows of teeth ensures their strong adhesion to each other during the assembly process, which gives strength and integrity to the container structure during heating and storage of the food product.

The proposed container design is unique in its simplicity in assembly and ease of operation, and without the use of various diaphragms (as in analogues), it is possible to control the mixing of chemical and physical reagents by making horizontal and vertical inlet and through holes in the inlet valve safety and coaxially with them the common through hole on the cover of the thermal module and on the thermal casing.

The presence of a thermal casing, in addition to thermal insulation, ensures the safety of the container during the heating of the food product and its safety, in addition, it provides an original design that is attractive and convenient for the consumer.

Thus, in comparison with the known analogues described above, the proposed container has a simple and safe design, easy to assemble and operate, it will easily find its consumer, since the process of heating a liquid product occurs quickly, efficiently and at the time of use retains the required product temperature .

In this connection, we can conclude that the invention is new, industrially applicable to obtain a useful technical result and patentable.
