Abstract: An instant cooling can, comprising an inner container received inside an outer container for containing beverage or foods. An instant cooling media is received inside a vacuum space between the outer container and the inner container. A ball is fastened in the neck portion of the can to seal the vacuum space. The ball is removed from its position permitting outside air to flow into the vacuum space to cause the instant cooling media to generate cooling gas for mixing with the beverage or foods contained inside the inner container so as to instantly drop the temperature of the beverage or foods.

Abstract: This invention relates to a bottom ejection type instant cooling easy-opener which can be instantly cooled down while producing a colorful gas and a whistling sound effect, wherein the easy-opener is having a circular convex (concave) seat made on the inner bottom and fixedly connected with one layer of adhesive material, a cylindrical cooler, a resilient sealing element and a metal plate; a metal injection needle having a rubber adapter connected at one end for further connection with a straw, and a whistle means set at the bottom of the circular convex (concave) seat, and wherein said metal injection needle is used to pierce through said resilient sealing element to let the instant cooling agent of the cylindrical cooler be exhausted to instantly cool down the easy-opener and to concomitantly produce a colorful gas and a whistling sound.
