The aerosol can was invented and patented in 1926 by Erik Rotheim. He invented 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. The patent was sold to a US company for 100,000 Norwegian kroners, but it wasn't until 1941 that it was first put to good use by Americans Lyle Goodhue and William Sullivan. They turned it into an instrument for the US military to fight the malaria mosquito in the Pacific during World War II. Aerosol spray products have three major parts; the can, the valve and the actuator or button. The can is most commonly lacquered tin plate and may be made of 2 or 3 pieces of metal crimped together. Aluminum cans are also common and are generally used for more expensive products. The valve is crimped to the rig of the can, the design of this component is important in determining the spray rate. The actuator is depressed by the user to open the valve; the shape and size of the nozzle in the actuator controls the spread of the aerosol spray.
