Abstract: A device for forming ice around an exterior surface of a container has an upper piece. The upper piece is an elongated tubular member having a hollow interior section and an open bottom and top end. A gasket assembly is coupled to an upper interior section of the upper piece. The gasket assembly creates a seal around a neck of the container to prevent water from rising above the neck of the container. A lower piece is provided and has an open top end and an opening formed in the bottom surface thereof. The open bottom end of the upper piece will mate with the open top end of the lower piece to form a watertight seal. A raised floor is formed in a bottom interior section of the lower piece. The raised floor allows water to collect and freeze underneath the bottom of the container. A cap is provided to close the opening in the bottom surface of the lower piece.
