The concept of an aerosol originated as early as 1790, when self-pressurized carbonated beverages were introduced in France. In 1837, a man called Perpigna invented a soda siphon incorporating a valve. In 1899, inventors Helbling and Pertsch patented aerosols pressurized using methyl and ethyl chloride as propellants.
On November 23, 1927, Norwegian engineer Erik Rotheim (also spelled Eric Rotheim) patented the first aerosol can and valve that could hold and dispense products and propellant systems. This was the forerunner of the modern aerosol can and valve (in 1998, the Norwegian post office issued a stamp celebrating the Norwegian invention of the spraycan).
During World War II, the U.S. government funded research into a portable way for service men to spray malaria-carrying bugs. Department of Agriculture researchers, Lyle Goodhue and William Sullivan, developed a small aerosol can pressurized by a liquefied gas (a fluorocarbon) in 1943. It was their design that made products like hair spray possible, along with the work of another inventor.
In 1953, Robert Abplanal invented a crimp-on valve "for dispensing gases under pressure." This put the manufacture of aerosol spray can products into high gear. Abplanal had created the first clog-free valve for spray cans. Abplanal also invented the "Aquasol" or pump spray, which uses water-soluble hydrocarbons as the propellant source. He realized that the fluorocarbons in the older aerosol cans damaged the ozone layer.
Spray paint was invented by Edward Seymour in 1949 (the first colour was aluminum). Edward Seymour's wife Bonnie suggested the use of an aerosol can filled with paint. Edward Seymour founded Seymour of Sycamore, Inc. of Chicago, USA, to manufacture his spray paints. |
