Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the cooling or heating of beverages in cans, and its purpose is to store beverages in cans at room temperature and individually add a chemical reaction material for heating or a chemical for cooling. Using a reaction material, each can is cooled or heated each time it is consumed.

To explain the drawings that are an example of the present invention, on the one hand [
A partition wall (3) made of a metal plate with good heat conductivity is provided in the middle of a cylindrical can (2) with a lid J (+), and a beverage is placed in the beverage filling chamber (4) for the purpose of heat radiation or heat absorption. fixing a metal plate (5) of the heated heat medium to the partition wall (3);
This is a beverage can in which a packaged chemical thermal reaction material (7) is placed in one container (6) and the container is sealed with a removable cover J (8).

In the present invention, the chemical eutectic as described above is packaged in a tear-resistant outer bag together with other chemicals and stored in one container (6) as a chemical-thermal reaction material (7).

There are two types of chemical-thermal-reactive materials (7): those that generate heat when mixed with chemicals, and those that absorb heat.For example, chemical-thermal-reactive materials that absorb heat are used when cooling drinks. Remove the "cover" (8) and remove the internal chemical thermal reaction material (
Take out the container (7), tear the easily tearable inner packaging from the top of the outer bag, mix the chemicals, and it will start to cool, then put the chemical thermal reaction material (7) into the container (6) again and close the cover.
Cover with (8). The chemical reaction material (7) is the partition wall (3)
A temperature difference is created between the beverage (4) and the partition wall (3), and the heat of the beverage (4) is transferred to the partition wall (3) by the heat transfer metal plate (5).
) and the beverage is cooled.

The present invention is characterized in that each can is equipped with a chemical thermal reaction material that can heat or cool each can, so it is convenient to carry the beverage at room temperature and cool down the Drink MS+ when you want to drink it. Furthermore, the current situation in retail stores is to use large refrigerators for constant cooling, but the present invention allows storage at room temperature, which eliminates wasted energy costs and increases the amount of storage, resulting in industrial effects. can be given.
