  • aerosol generating devices for inhaling flavors without burning materials are known.
  • electronic cigarettes are known as such aerosol generating devices.
  • Electronic cigarettes atomize an aerosol-forming material that contains a flavor such as nicotine and supply the generated aerosol to the user's mouth, or atomize an aerosol-forming material that does not contain a flavor such as nicotine and supply the generated aerosol to the user's mouth by passing it through a flavor source (e.g., a tobacco source).
  • a flavor source e.g., a tobacco source
  • Some electronic cigarettes include a tank or reservoir that contains a liquid for generating an aerosol, and a heater that atomizes the liquid.
  • Some such electronic cigarettes are known to have an atomizer assembly in which a coil-shaped heater is wrapped around a wick that is fluidly connected to the tank (see, for example, Patent Document 1).
  • Tanks or reservoirs that contain liquids are generally made from synthetic resins such as plastics, from the standpoint of cost and moldability.
  • fossil fuels are often used as the raw material for such tanks or reservoirs.
  • disposing of such tanks or reservoirs after use can be costly.
