Abstract: A device that attaches to a bottle's neck has a base that secures to the bottle's neck and has two passages that traverse the base. The first passage leads to an enclosure located above the base that holds cooling material and optionally has a conduit that improves the heat exchange between a dispensing liquid and the cooling material retained in the enclosure. The exit passage of the enclosure has in at least one embodiment a valve. The second passage through the base forms a vent line that is located entirely below the enclosure and allows air to flow into the bottle as bottle's contents are dispensed through the first passage.

Abstract: A device to cool a liquid during the pouring procedure is provided. The device comprises an enclosure having a top portion and a bottom portion. Generally mounted to the bottom portion is a base for mounting the device to the neck of a bottle. Optionally mounted to the top portion is a spout which generally comprises a valve adapted to control the temperature of the poured liquid by controlling the flow thereof. The bottom portion and the top portion respectively comprise a first and a second openings between which extends a preferably metallic coil conduit. Within the enclosure, the conduit is surrounded by a low freezing cooling material. The device further comprises a vent passage extending in the base portion. Upon pouring the liquid from a bottle, the liquid circulates through the conduit which is in close contact with the cold cooling material, effectively cooling the liquid.
