Abstract
A double walled container is provided for insulating a beverage. An outer insulating shell or container is secured to the inner container that holds the beverage. A gap exists between the outer container and inner container and the air in the gap acts as an insulating barrier. The inner container is preferably a standard aluminum container. The outer container is preferably made from aluminum or a plastic polymer. The outer container may have annular or longitudinal grooves that assist in securing the outer container to the inner container, and the grooves may also provide an enhanced gripping surface as well as a visually pleasing aesthetic design. The outer container may include a base, or the base may be eliminated in favor of a sleeve configuration for the outer container.
