  "country": "US",
  "title": "How the First Aerosol Spray Can Works",
  "original_title": "Dispensing apparatus",
  "summary": "A 1941 invention by Lyle Goodhue and William Sullivan that created the modern aerosol spray can by using a liquefied gas to propel liquid contents.",
  "what_it_does": "The patent describes a pressurized container that uses a liquefied gas propellant to force a liquid product out through a nozzle. When the valve is opened, the difference in pressure between the inside of the can and the outside causes the liquid and propellant mixture to rush out. As the propellant evaporates, it breaks the liquid into a fine mist or aerosol. This mechanism allowed for the portable, self-contained spraying of insecticides, which was the original intended use during World War II.",
  "what_it_does_not_cover": [
    "Does not cover non-pressurized pump-action spray bottles.",
    "Does not cover systems that use mechanical air pumps instead of liquefied gas propellants.",
    "Does not cover the chemical composition of the liquid being sprayed."
