Definitions

  • the present invention relates to an aerosol-generating article having an integrated heating element.
  • the present invention also relates to an electrically heated aerosol-generating system comprising an aerosol-generating article having an integrated heating element, and to methods of manufacturing tobacco plugs and aerosol-generating articles each having an integrated heating element.
  • One type of aerosol-generating system is an electrically operated smoking system.
  • Known handheld electrically operated smoking systems typically comprise an aerosol-generating device comprising a battery, control electronics and an electric heater for heating a smoking article designed specifically for use with the aerosol-generating device.
  • the smoking article comprises a plug of an aerosol-forming substrate, such as a tobacco plug, and the heater contained within the aerosol-generating device is inserted into the aerosol-forming substrate when the smoking article is inserted into the aerosol-generating device.
  • the electric heater may become contaminated with material from the aerosol-forming substrate during use and cleaning the electric heater inside the device can be difficult. In some cases, it may be necessary to dispose of the entire device if the heater cannot be adequately cleaned. Sometimes removal of the smoking article from the device is also difficult, which may result in the need for a dedicated extraction tool to facilitate removal of the smoking article from the device without damaging the heater.

  • the resistive heating element comprises an upstream portion protruding from an upstream end of the tobacco plug, wherein the upstream portion of the resistive heating element comprises at least two heater electrical contacts for receiving a supply of electrical energy from at least two device electrical contacts when the aerosol-generating article comprising the resistive heating element is inserted into an aerosol-generating device.
  • aerosol-generating article refers to an article comprising a tobacco plug that, when heated, releases volatile compounds that can form an aerosol.
  • aerosol-generating device refers to a device that interacts with an aerosol-generating article to generate an aerosol.
