Abstract
A device for controlling the temperature of a bottle, jar or the like is disclosed, characterized in that the desired temperature of the bottle may be selected and maintained by mechanically adjusting the heat transfer surface area of the device. The device includes inner and outer containers arranged in concentrically spaced relation, each of the containers having a vertically arranged tubular wall portion open at its upper end. The inner container is formed from a heat conducting material, and a first fluid medium having a given initial temperature is arranged in the space between the inner and outer containers. The bottle is arranged within the inner container as is a heat energy transfer control device which controls the transfer of heat energy between the bottle and the first fluid medium through the inner container, thereby to control the temperature of the bottle.
