Aerosol spray patent

In 1939, the first U.S. patent for dispensing liquids under pressure from a disposable container was issued to Julius Seth Kahn of New York City (No. 2,170,531). The patent was titled "Apparatus For Mixing a Liquid With a Gas," but was the predecessor of the aerosol spray can. In this case, the patent more particularly specified a use for whipping cream "by discharging the cream and gas mixture through a constricted orifice." The cream could be contained in a common soda-pop glass bottle. Gas could be introduced at controlled pressure. An inexpensive valve discharged the whipped cream. Its use was extended to applications such as dispensing paints, pharmaceuticals and insecticides.
