Abstract
A cooling system inside a beverage can bottom which is activated by pressing a bubble or combination or bubbles formed in the top of the can. The bubbles are internally connected to pin rods interconnected to one or more capsules located in the bottom of the can. The capsules contain a gas, usually in a liquid form such as liquid nitrogen or air. Pressure on a bubble causes the pin rod to activate a capsule or capsules thereby releasing gas into a closed loop plate system positioned within the can. The gas is of a type which causes the plate system to cool, thereby cooling the beverage in contact with the plate system.
