The aerosol spray canister invented by USDA researchers, Lyle Goodhue and William Sullivan.. The concepts of aerosol probably go as far back as 1790. [1] The first aerosol spray can patent was granted in Oslo in 1927 to Erik Rotheim, a Norwegian chemical engineer, [1] [2] and a United States patent was granted for the invention in 1931. [3]
In the late 1960s, spray bottles with trigger-style actuators appeared and quickly became popular, as this design was less fatiguing to use. The original pump-style bottle remained more popular for applications like non-aerosol deodorants, where size was a factor and repeated pumps were not required.
Spray nozzles can have one or more outlets; a multiple outlet nozzle is known as a compound nozzle. Multiple outlets on nozzles are present on spray balls, which have been used in the brewing industry for many years for cleaning casks and kegs.

A diagram showing the operation of a tapered element oscillating microbalance instrument. The TEOM uses a hollow glass tube as a microbalance. Incoming particles are deposited on a filter at the tip of the tube, and the added mass causes a change in its oscillation frequency which is detected electronically.

In 1926, Norwegian engineer Erik Rotheim applied for the first patent for an aerosol can that could hold products and dispense them with the use of propellants. By 1931, Rotheim was recognized for his invention and considered a pioneer in this field. [4] In the 1940s, the paint industry took another step forward with the invention of the ...
