When a chemical change occurs, a new substance is always produced, so that energy corresponding to the energy difference of the substance before and after the reaction is released or absorbed. An exothermic reaction is a reaction in which reactants release heat to the surroundings while reacting, and an endothermic reaction is a reaction that absorbs ambient heat. When the temperature change is measured during the chemical reaction, if the reactant shows a temperature higher than the initial temperature, it is called an exothermic reaction. If the reactant shows a low temperature, it is called an endothermic reaction.

In the present invention, a cooling material such as malic acid (molecular formula: C4H6O5) and calcium carbonate (potassium bicarbonate, molecular formula: KHCO3), which is harmless to the human body and performs an endothermic reaction when used as a cooler, And a cooler capable of cooling the beverage by reacting water with a catalyst.

In addition, the chemical that performs an exothermic reaction when used as a warmer is harmless to human body.

Aluminum, or calcium oxide, etc., are mainly used to heat a beverage by reacting water with a catalyst.

In order to heat or cool such a self-cooling can or a PET beverage, there is no large increase in the container size or weight of the internal circulation type cooling device, the material of the container must be harmless to the human body, It should be eco-friendly product. In particular, the cost of beverages should not be an excessive cost burden.

Such an internal type heater or cooler needs a technology capable of realizing harmless to the human body, selecting an environmentally friendly cooling material, fast heat transfer material with beverage, structure capable of mass production, and cost competitive structure.

Therefore, in the present invention, among the food and beverage additive compounds, a cooling substance which reacts with water in the form of a powdery organic acid compound and a carbonate compound as a catalyst and which performs an endothermic reaction as a discharge of carbon dioxide gas is selected and a cooling reaction is caused by a simple structure and simple operation In order to achieve a rapid cooling effect, a self-cooler capable of prompting rapid heat transfer to the inner surface of the beverage is realized.

When the reaction heat of the endothermic reaction material is applied to the cooling can, the product after the reaction is formed with water and carbon dioxide. Such a product is harmless to the human body because it is not toxic, and is a good cooling method without affecting the environment. However, when the beverage is cooled by using the endothermic reaction, the internal pressure is rapidly increased due to the gas and bubbles generated after the reaction, which makes it difficult to control the pressure. In order to commercialize the cooling can structure that can solve these problems, it must be safe, simple, and mass-produced at a low cost so that consumers can enjoy soft drinks without hesitation.

Therefore, the present invention can obtain an efficient cooling effect by controlling the foam and the internal pressure by using a simpler structure than the conventional one.

A heating device heats the container using the heat of the reaction in the exothermic reaction. Since the structure is as described above and carbide is used, the gas generated during the reaction is an environmentally friendly gas free from harm to the human body.

The carbon dioxide gas generated in the cartridge inside the container can be used to embellish the temperature of the beverage or heat the beverage to the upper gap of the holder.

The heat is exchanged with the beverage inside the container, its own heat, and all the surfaces that come into contact with the outer surface of the cooler. The effect of increasing or decreasing the temperature of the beverage as the endothermic or exothermic reaction progresses over 1 to 25 minutes .

In addition, the structure of the internal circulation type self-heating and cooler can effectively control the rapid internal pressure increase due to the reaction products generated during the semi-thermal reaction or the endothermic reaction when the beverage is heated or cooled using the exothermic reaction or the endothermic reaction, It is a device that has the structural advantage to obtain the effect.

The structure of the present invention is a form in which a cartridge 2 for causing a heat or an endothermic reaction is mounted inside a general beverage container 1. A cartridge 1 formed of two cartridges serving as a self heater or a cooler is provided with a first cartridge 20 for storing a compound 6 causing an exothermic reaction or an endothermic reaction and a second cartridge 20 for storing water 4 The upper portion of the second cartridge 30 is formed of a separate thin foil shielding film and the upper portion of the first cartridge abutting the upper portion of the second cartridge 30 is provided with sharp projections 7 When the protrusion 7 of the first cartridge 20 abuts against the upper portion of the second cartridge 30 and breaks, the water 4 stored in the second cartridge 30 and the first cartridge 20 ) Is contacted with the compound (6) to generate a heat or an endothermic reaction,

The beverage inside the container, its own heat, the heat exchange with the beverage in all the surfaces that come into contact with the outer surface of the cooler, and the effect of heating or endothermic reaction for 1 to 25 minutes is enough to raise or lower the temperature of the beverage. . In addition, the structure of the internal circulation type self-heating cooler uses a heat or an endothermic reaction to heat the beverage, and when the coolant is cooled, a rapid internal pressure increase due to a reaction product generated during a heat reaction or an endothermic reaction, And has the structural advantage of being able to obtain efficient heat or cooling effect by effectively discharging it.
