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.
