Abstract: A portable cooler for carrying and chilling a standard beverage container having a threaded cap. The container cap is removed, and the container is threaded into the cooler. The beverage container is inverted when the cooler is upright. The container neck threads into a socket which is in liquid communication with a faucet external to the cooler. A shroud engages the base of the cooler, sealing a chilled chamber defined between the beverage container and the shroud, and retaining the beverage container therein. In an alternative embodiment, the container can be oriented in an upright position, and used in that position. An optional cap cooperates with the shroud or the beverage container. The cap is removable to expose the container, or may be provided with spill and vent holes through which beverage is dispensed. A handle is also optionally provided, so that the cooler can be handled in a manner likened unto a mug or pitcher.

Abstract: A portable cooler for carrying and chilling a standard beverage container having a threaded cap. The container cap is removed, and the container is threaded into the cooler. The beverage container is inverted when the cooler is upright. The container neck threads into a socket which is in liquid communication with a faucet external to the cooler. A cooler cap threads to the body of the cooler, sealing a chilled chamber defined in the cooler, and retaining the beverage container therein. In an alternative embodiment, this cap cooperates with the beverage container, so that the container can be inserted upright, and used in that position. A handle is also optionally provided, so that the cooler can be handled in the manner of a pitcher. A refrigeration plant, which may be a miniature compression cycle type or a Peltier effect type, is housed inside the cooler. An electrical plug enables connection to a suitable electrical power source.
