Abstract
Abstract A portable cooler which may be carried in back-pack style is adapted to store and automatically dispense a number of cans of beverage. The cooler is comprised of a box-like chamber having self-supporting thermally insulative material on its exterior surfaces. One or more removable coolant-confining containers are positioned within the chamber, each container having a serpentine contour of horizontally elongated recesses adapted to hold beverage cans and permit their vertical descent to a door positioned adjacent the bottom of the chamber. The chamber is held within a snug-fitting fabric carrying jacket having a zippered lid and closure for the door, and carrying straps.
