Patent

CA 2379646

A self-cooling can (10) which is suitable for cooling 300m1 of beverage by 30 °F in a maximum of 3 minutes comprises an internal evaporator (30) and an absorber unit (20) which is fixed typi-cally to the base of the can. Cooling is initiated by providing a vapour path from the evaporator (30) to a desiccant region of the absorber unit (20). Heat is removed from the vapour and/or any heat due to the reac-tion with the desiccant (24) by heat sink material (26) around the desic-cant region (22).

L'invention porte sur une canette (10) à refroidissement intégré qui est appropriée pour refroidir 300 ml de boisson à 30 DEG F en 3 minutes maximum. Cette canette comprend un évaporateur (30) interne et une unité (20) d'absorption qui est fixée généralement à sa base. Le refroidissement se déclenche par génération de vapeur de l'évaporateur (30) dans une région déshydratante de l'unité (20) d'absorption. La chaleur est éliminée de la vapeur et/ou toute chaleur due à la réaction avec l'agent déshydratante (24) au moyen d'un matériau (26) thermoconducteur entourant la région (22) déshydratante.
