Abstract
An ice chest or portable cooler is disclosed which includes a unique construction which enables the cooler to maintain the contents therein at or below a desired temperature for an extended period of time. The top, walls, and bottom of the cooler utilize a shell which includes an inner and outer layer of a plastic and a relatively thick layer of an insulation material between the layers of plastic. The construction adds strength and rigidity to the cooler, while not increasing the weight as a result of the relatively light insulation material.
