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]
The disposable spray can was largely undeveloped until Lyle Goodhue devised a practical version and filed for a patent in 1941 [9] while working for the U.S. Department of Agriculture (USDA). Goodhue's earliest aerosol propellant idea came to mind when he worked in 1929–1930 as a research chemist on lacquer formulations at the DuPont Chemical ...
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. [2] Spray nozzles range from those for heavy duty industrial uses to light duty spray cans or spray ...
Depending on the sprayer, the nozzle may or may not be adjustable, so as to select between squirting a stream, aerosolizing a mist, or dispensing a spray. In a spray bottle, the dispensing is powered by the user's efforts, as opposed to the spray can, in which the user simply actuates a valve and product is dispensed under pressure.
A key component in Silly String is its aerosol spray can and the propellant that ejects the product mixture from the can. The product originally used chlorofluorocarbon propellant Freon 12 mixed with Freon 11, both part of a group of compounds that damage the ozone layer. In 1978, the United States banned the use of CFCs like Freon 11 and 12 in ...
Aerosol spray can. A spray is a dynamic collection of drops dispersed in a gas. [1] The process of forming a spray is known as atomization. A spray nozzle is the device used to generate a spray. The two main uses of sprays are to distribute material over a cross-section and to generate liquid surface area.
