Definitions

  • the present disclosure relates to an aerosol-generating device for use with an aerosolgenerating article.
  • the present invention relates to an aerosol-generating device having a recess comprising one or more air inlets and one or more aerosol outlets.
  • the present disclosure also relates to an aerosol-generating system comprising the aerosol-generating device and an aerosol-generating article.
  • Aerosol-generating articles in which an aerosol-generating substrate, such as a tobacco containing substrate, is heated rather than combusted are known in the art. In heated aerosolgenerating articles, the aerosol is generated by heating the aerosol-generating substrate.
  • aerosol-generating system is an electrically operated smoking system.
  • Known handheld electrically operated smoking systems typically comprise an aerosol-generating device comprising a rechargeable battery, control electronics and an electric heater for heating an aerosol-generating article designed specifically for use with the aerosol-generating device.
  • the aerosol-generating article comprises an aerosol-forming substrate, such as a tobacco rod or a tobacco plug, and the heater contained within the aerosol-generating device is inserted into or located around the aerosol-forming substrate when the aerosol-generating article is inserted into the aerosol-generating device.
  • a heating element may be provided in an aerosol-generating device for generating an inhalable vapor.
  • Such a device may heat the aerosol-generating substrate contained in the aerosol-generating article without burning the aerosol-generating substrate. In doing so, the aerosol-generating substrate may generate an aerosol which may be delivered to a user.
  • Such aerosol-generating articles may take the form of a conventional cigarette. Where this is the case, the aerosol-generating substrate may be wrapped in cigarette paper. This approach may be appropriate where the aerosol-generating substrate comprises strands or spaghettis of material, for example strands of cast leaf tobacco or strands of shredded tobacco.
  • aerosol-generating articles may be prone to leakage of the aerosol-generating substrates during storage, handling and use thereof. Leakage of the aerosol-generating substrates may be exacerbated by high environmental temperatures and humidities. Loss of aerosol-generating substrates through leakage may disadvantageously reduce the lifespan of the aerosol-generating article comprising the aerosol-generating substrate. Leakage of aerosol-generating substrates may negatively impact the overall performance of the aerosol-generating article. For example, leakage of aerosolgenerating substrates may negatively impact the consistency of the inhalable aerosol generated by an aerosol-generating system comprising the aerosol-generating article.
  • an aerosol-generating article comprising a container may be provided.
  • Such an aerosol-generating article may be able to retain different forms of aerosol-generating substrate, such as granulated or powdered aerosol-generating substrate.
  • Such an aerosol-generating article comprising a container may be readily handled and manipulated by a consumer when it is being used in combination with a suitable aerosol-generating device.
  • aerosol-generating devices of the prior art may not be suitable for heating aerosol-generating articles comprising a container.
  • inserting a heating element into an aerosol-generating article comprising a container may disadvantageously cause the aerosolgenerating substrate to leak out of the container.
  • existing heaters configured to externally heat aerosol-generating articles may not provide efficient heating sufficient to generate a consistent aerosol from an aerosol-generating article comprising a container.
  • parts of the aerosolgenerating substrate of an aerosol-generating article may receive less airflow than other parts of the aerosol-generating substrate when used with an aerosol-generating device.
  • an aerosol-generating device may be configured such that an airflow pathway through the aerosolgenerating device does not contact parts of an aerosol-generating substrate of an aerosolgenerating article. This may be a particular issue when the aerosol-generating article comprises a container because the aerosol-generating substrate may be distributed throughout the container.
  • release of active ingredients into an aerosol such as one or both of nicotine and flavours, from some parts of an aerosol-generating substrate of an aerosol-generating article may be reduced when used with an aerosol-generating device. Consequently, poor aerosol generation and delivery may occur during a user experience when the parts of an aerosolgenerating substrate of an aerosol-generating article which have the most contact with the airflow pathway through the aerosol-generating device are depleted. Depletion of parts of an aerosolgenerating substrate of an aerosol-generating article which have the most contact with the airflow pathway through the aerosol-generating device may be rapid. Therefore, in particular, at the end of the user experience poor aerosol generation and delivery to the user may occur.
