Abstract

The present invention is a device releasably attachable to a beverage-containing can or bottle that is operable to selectively heat or cool a beverage dispensed from the container and through the device for consumption by an individual. The device includes an outer sleeve securable to the beverage container and an inner cartridge containing reactants utilized to generate an endothermic or exothermic reaction within the cartridge. The reaction created by the reactants heats or cools beverages dispensed from the container as the beverage flows through conduits disposed in thermal contact with the reactants that extend from a beverage inlet adjacent a lower end of the cartridge to a dispensing outlet adjacent an upper end of the cartridge. The device is removable from the container for use with additional containers, or for disposal and replacement of the cartridge within the sleeve after each use.
