A liquid cooler comprising an elongate cylindrical container for holding a liquid to be cooled, and a buoyant cylindrical stainless steel cartridge containing a refrigerant, that is located in the container. The container is open-topped and is closeable via a dome-shaped moulded polyethylene lid having a spout. The container has a surrounding wall comprising an inner wall section of stainless steel having a relatively high thermal conductivity and an outer wall section. The outer wall section comprises a number of layers of material having relatively high thermal insulation properties. The cartridge has an air pocket trapped therein to provide buoyancy therefor which causes the cartridge to rise, in use, within the container. As such, the container and the cartridge define a space between them along which relative flow of liquid occurs when the cartridge rises within the container, thereby enhancing cooling of the liquid.

[ What is claimed is:] [1.] A liquid cooler comprising:a container comprising at least one surrounding wall of a materialhaving relatively high thermal insulation characteristics, the surrounding wall defining an internal compartment for holding a liquid to be cooled and having an opening through which the liquid can be introduced into and removed from the internal compartment; anda buoyant cartridge comprising at least one surrounding wall defining an internal compartment for holding a relatively cool substance, the surrounding wall of the cartridge being of a material having a relatively high thermal conductivity and having dimensions and a configuration that permits it to be slidably accommodated in the container, whereby liquid to be cooled moves from a position above the cartridge to a position below the cartridge as the cartridge slidably rises in a buoyant manner.
