History

The original inventor of the cooler is unknown, with versions becoming available in various parts of the world throughout the 1950s.

The portable ice chest was patented in the USA by Richard C. Laramy of Joliet, Illinois. On February 24, 1951, Laramy filed an application with the United States Patent Office for a portable ice chest (Serial No. 212,573).[2] The patent (#2,663,157) was issued December 22, 1953.

In 1952, the portable Esky Auto Box was released in Australia by the Sydney refrigeration company Malley’s. Made from steel and finished in baked enamel and chrome, with cork sheeting for insulation, the Esky became the first mass-produced cooler on the market. The brand found huge success and by 1960, 500,000 Australian households owned one (in a country of approximately 3 million households at the time).

The Coleman Company popularized the cooler within the USA with its initial offering of a galvanized cooler in 1954. Three years later, Coleman developed a process to make a plastic liner for coolers and jugs.
