Definitions

  • the present disclosure relates to an aerosol generating article for use with an aerosol generating device.
  • the present invention relates to an aerosol generating article for use with an aerosol generating device, the aerosol generating article comprises an odour inhibition substrate.
  • Aerosol generating articles in which an aerosol-forming substrate, such as a tobacco containing substrate, is heated rather than combusted are known in the art.
  • an aerosol is generated by the transfer of heat from a heat source to a physically separate aerosol-forming substrate or material, which may be located in contact with, within, around, or downstream of the heat source.
  • volatile compounds are released from the aerosol-forming substrate by heat transfer from the heat source and are entrained in air drawn through the aerosol generating article. As the released compounds cool, they condense or nucleate to form an aerosol.
  • Some aerosol generating articles of the prior art comprise a combustible heat source upstream of an aerosol-forming substrate.
  • the aerosol-forming substrate may comprise tobacco.
  • heat from the combustible heat source heats the aerosol-forming substrate to volatilise compounds which cool and condense or nucleate to form an aerosol.
  • the aerosol-forming substrate may be heated by a separate aerosol generating device.
  • aerosol-generating devices for use with aerosol generating articles. Such devices include, for example, electrically heated aerosol generating devices in which an aerosol is generated by the transfer of heat from one or more electrical heater elements of the aerosol-generating device to the aerosol-forming substrate of a heated aerosol generating article.
  • the process of heating the aerosol-forming substrate may also lead to the generation of unpleasant odours which is undesirable.
  • This problem may be particularly pronounced when the aerosol-forming substrate comprises tobacco.
  • the aerosol generated by the aerosol generating device remains in the air and the surrounding environment after the user has finished using the aerosol generating device. This is known as “off-odour”.
  • improper use or maintenance of the aerosol generating device can lead to a distinct unpleasant odour. This may occur when, for example, an electric heater element of an aerosol generating device is not properly cleaned. This is known as “malodour”.
  • both off- odour and malodour may be experienced by both the user of the aerosol generating article and by others in close proximity to the aerosol generating article. Accordingly, it would be desirable to provide an aerosol generating article in which the unpleasant odours, such as off-odour and malodour, caused by the heating of the aerosol forming substrate are reduced or prevented.
  • the present disclosure relates to an aerosol generating article.
  • the aerosol generating article comprises an aerosol-forming substrate.

More importantly the user, and others in close proximity to the aerosol generating article, are unable to identify the off-odour and malodour caused by the heating of the aerosol-forming substrate.
  • any unpleasant odours caused by the heating of the aerosol forming substrate are not perceived.
  • the term “aerosol generating article” is used herein to denote an article wherein an aerosol-forming substrate is heated to produce and deliver inhalable aerosol to a consumer.
