A round beverage container with a chill sleeve is provided having a molded plastic wall in the shape of a cup, a mug, or a pitcher. A sleeve containing a chill medium is in the shape of a truncated conical cylinder, and is positioned in the container to be lodged therein at a selected mounting location and secured by snap-action sealing and retaining rings. A bottom disk, also containing the chill medium, snaps into the container's bottom edge to form the bottom of the container. This bottom disk is sealed to the inside wall of the container by snap-action sealing and retaining rings. Sonic welding can be employed as an alternative to sealing and securing rings. A quantity of water-based chill medium is metered into the hollow cavities when the sleeve and the bottom disk are charged, taking into consideration the expansion of the chill medium (water) upon a change of phase. The wall of the container is tapered and the side walls of the sleeve and of the bottom disk are each tapered to match the taper of the container wall. A bottom face (wall) for each of the insertable chill sleeve and the bottom disk is first separate from the remainder and then snapped into place to seal the respective chill sleeve and bottom disk after they are filled. The bottom face of the chill sleeve is toroidal-shaped.
