Abstract
Abstract A double-walled drinking vessel having a heat maintenance chamber between an inner wall and outer, transparent, wall of the vessel. A fluid is placed between the walls, and this fluid is either heated or cooled, depending upon the beverage that is to be employed in the vessel. An annular base in the form of a skirt is placed around and below the bottom of the vessel, and it has a plurality of spaced orifices which provides for air circulation underneath the vessel, this preventing condensation from occurring on a tabletop or other supporting surface. The state of the temperature maintenance chamber is viewable through the transparent outer wall.
