Abstract: A system for externally cooling a beverage holder holding a specific amount of beverage comprises a cooling housing having an inner wall and an outer wall. The inner wall is made of thermal conductive material for contacting at least a part of the beverage holder. The cooling housing defines an inner compartment including at least two separate, substantially non-toxic reactants, causing when reacting with one a other a non-reversible, entropy-increasing reaction producing substantially non-toxic products in a stoichiometric number. The at least two separate substantially non-toxic reactants are initially included in the inner compartment separated from one another and causing, when reacting with one another in the non-reversible, entropy-increasing reaction, a heat reduction of the beverage within the beverage holder.

Abstract: The present invention relates to a container for storing a beverage, the container having a container body and a closure and defining an inner chamber, the inner chamber defining an inner volume and including a specific volume of the beverage. The container further includes a cooling device having a housing defining a housing volume. The cooling device includes at least two separate, substantially non-toxic reactants causing an entropy-increasing reaction producing substantially non-toxic products in a stoichiometric number. The at least two separate substantially non-toxic reactants initially being included in the cooling device are separated from one another and causing an entropy-increasing reaction and a heat reduction of the beverage of at least 50 Joules/ml beverage. The cooling device further includes an actuator for initiating the reaction between the at least two separate, substantially non-toxic reactants.
