Patent

CA 2380931

A self-cooling can (10) comprising an evaporator unit (30) within the can (10) and an absorber unit (20) provided outside the container body (10). A beverage within the can (10) is cooled by means of vapour which passes from the evaporator (30) to the absorber (20) when these are connected so as to provide a vapour path between the two. The path for water vapour, for example, to pass from the evaporator (30) to the absorber (20) is formed by rupturing a panel (40) between evaporator (30) and the absorber (20) when the can (10) and part or all of the absorber (20) are rotated relative to each other.

L'invention porte sur une canette auto-rafraichissante (10) comportant un évaporateur (30) placé dans la canette (10) et un absorbeur (20) placé à l'extérieur du corps (10) du récipient. La boisson contenue dans le récipient (10) est refroidie par la vapeur passant de l'évaporateur (30) à l'absorbeur (20) quand ils sont couplés pour former un passage les reliant. Un tel passage, allant par exemple de l'évaporateur (30) à l'absorbeur (20), se crée par la rupture d'un opercule (40) les séparant lorsqu'on fait tourner l'un par rapport à l'autre la canette (10) et tout ou partie de l'absorbeur (20).
