It relates to a beverage can having a self-cooling function and a method for producing the same.

In general, the cans used as beverage containers are made of two pieces or three pieces using aluminum or steel, and in the case of two pieces, the lower side and the body are made of one part and the upper side is made of another part. In the case of three pieces, the upper surface, the lower surface, and the body part are combined as the respective parts.

On the other hand, in order to drink the beverage stored in the can cold, you need to use a refrigerator, ice box (ice box), vending machine (vending machine), but the invention of the cooling can can be used regardless of the place and time, such as in the outdoors or in the car It's a cool way to drink.

The present invention is designed to eliminate the problems that have been inconvenient so far, and a container containing a refrigerant to cool the beverage inside the can is installed separately so that the refrigerant starts to operate (eject) and the refrigerant vaporizes.
