  • Patent number: 5129238
    Abstract: A drinking container having a cylindrical side wall attached along threads at an external top portion to a screw on cap member sealed to the side wall to prevent leakage of fluid from the container. The cap member is integral with a freezable insert containing an aqueous solution with a downwardly descending freezable insert containing an aqueous solution with a freezing point below the freezing point of water. The freezable insert can have its contents frozen and then returned to a position within the cylindrical side wall of the container to cool a liquid placed within the container. Alternatively, the freezable insert is separate from the cap and is screwed into a central bore of the cap after being frozen.
