Abstract
The insulated beverage container is a container, such as a coffee cup, providing thermal insulation for the user's hand. The container includes a vertically extending annular wall and a base, forming a beverage-receiving cup. A plurality of tubes are secured to an outer surface of the annular wall. Each tube is hollow and defines an air passage therein, and is further elongated along the vertical direction, having upper and lower air flow apertures formed therethrough. In use, heat generated by the beverage heats the air contained within the tubes. As the air rises within the tubes, ambient air at a lower temperature is drawn through the lower air flow apertures and the heated air is expelled through the upper air flow apertures, maintaining a flow of cooled air from the environment through the tubes.
