Cooler buddy

Abstract

A cooler buddy has a generally rectangular, prismatic form. The invention floats and orients upright upon double walled construction. The invention has a rectangular lid upon an outer tub of hollow rectangular shape. The lid has a recess and a perimeter depending lip. At each corner, the lid has a thin tab for its removal from the outer tub. The outer tub has a base and a perimeter flange spaced above it. Inwardly, the invention has an inner pan of rectangular form but of less depth than the outer tub. The inner pan has its base and its perimeter flange. The two flanges join by welding leaving a space between the outer tub and the inner pan. The outer tub and the space cooperate to displace enough water to float the invention when loaded. The outer tub and the inner pan are transparent.
