Abstract: A thermally insulated cooler for keeping canned drinks cold has a tubular shape. Cans are stacked in the tube one atop the other, and the inner diameter of the tube fits closely around the circumference of the cans. The length of the cooler can be sized to accommodate various numbers of cans. The cooler is of double wall construction, and the space between the walls is either a vacuum or a thermally insulating material. A coil spring in the bottom of the tube biases the cans through the upper end of the tube. A retaining ring mounted to the open end of the tube has an opening with radially inwardly projecting tabs that grip a can as the spring feeds it through the opening. The tabs hold the can partially protruding from the tube until a user affirmatively removes the can from the tube.
