Definitions

  • the present disclosure relates to a consumable for use in a smoking substitute system and particularly, although not exclusively, to a heat-not-burn (HNB) consumable.
  • HNB heat-not-burn
  • the smoking of tobacco is generally considered to expose a smoker to potentially harmful substances. It is generally thought that a significant amount of the potentially harmful substances are generated through the heat caused by the burning and/or combustion of the tobacco and the constituents of the burnt tobacco in the tobacco smoke itself.
  • Conventional combustible smoking articles such as cigarettes, typically comprise a cylindrical rod of tobacco comprising shreds of tobacco which is surrounded by a wrapper, and usually also a cylindrical filter axially aligned in an abutting relationship with the wrapped tobacco rod.
  • the filter typically comprises a filtration material which is circumscribed by a plug wrap.
  • the wrapped tobacco rod and the filter are joined together by a wrapped band of tipping paper that circumscribes the entire length of the filter and an adjacent portion of the wrapped tobacco rod.
  • a conventional cigarette of this type is used by lighting the end opposite to the filter, and burning the tobacco rod. The smoker receives mainstream smoke into their mouth by drawing on the mouth end or filter end of the cigarette.
  • Such smoking substitute systems can form part of nicotine replacement therapies aimed at people who wish to stop smoking and overcome a dependence on nicotine.
  • Smoking substitute systems include electronic systems that permit a user to simulate the act of smoking by producing an aerosol (also referred to as a“vapour”) that is drawn into the lungs through the mouth (inhaled) and then exhaled.
  • aerosol also referred to as a“vapour”
  • the inhaled aerosol typically bears nicotine and/or flavourings without, or with fewer of, the odour and health risks associated with traditional smoking.
  • smoking substitute systems are intended to provide a substitute for the rituals of smoking, whilst providing the user with a similar experience and satisfaction to those experienced with traditional smoking and with combustible tobacco products.
  • Some smoking substitute systems use smoking substitute articles that are designed to resemble a traditional cigarette and are cylindrical in form with a mouthpiece at one end.
  • HNB heat not burn
  • a typical HNB smoking substitute system may include a device and a consumable.
  • the consumable may include the tobacco material.
  • the device and consumable may be configured to be physically coupled together.
  • heat may be imparted to the tobacco material by a heating element of the device, wherein airflow through the tobacco material causes moisture in the tobacco material to be released as vapour.
  • a vapour may also be formed from a carrier in the tobacco material (this carrier may for example include propylene glycol and/or vegetable glycerine) and additionally volatile compounds released from the tobacco. The released vapour may be entrained in the airflow drawn through the tobacco.
  • the vapour passes through the consumable (entrained in the airflow) from an inlet to a mouthpiece (outlet), the vapour cools and condenses to form an aerosol for inhalation by the user.
  • the aerosol will normally contain the volatile compounds.
  • HNB smoking substitute systems heating as opposed to burning the tobacco material is believed to cause fewer, or smaller quantities, of the more harmful compounds ordinarily produced during smoking. Consequently, the HNB approach may reduce the odour and/or health risks that can arise through the burning, combustion and pyrolytic degradation of tobacco.
  • the aerosol passing from the mouthpiece may not be in a desirable state.
  • the present disclosure relates to an aerosol-forming article e.g. a smoking substitute article such as an HNB consumable.
  • the aerosol-forming article of the invention provides a means for the user to tailor their experience thereby facilitating increased enjoyment of the product.
  • a heat not burn (HNB) consumable comprising an aerosolforming substrate, and a terminal filter element, wherein the axial length of the terminal filter element is adjustable.
  • the user is able to tailor their experience of the consumable to meet their own requirements.
  • a user may decide to retain the entire axial length of the terminal filter element thereby providing the highest level of filtration and a less harsh experience.
  • they may decide to adjust the axial length of the filter element to vary the intensity. For example, they may reduce the axial length of the terminal filter element to reduce the level of filtration and increase the intensity of their experience.
  • the invention removes the need for complex and expensive HNB devices which provide different levels of heating to vary the intensity of the user experience.
  • the present invention provides a consumable with an integrated variability in intensity, such that the user experience can be tailored regardless of capabilities of the device which is used to heat the consumable.
  • variable intensity provided by the present invention offers particular advantages when applied to a HNB consumable.
  • a traditional cigarette provides a relatively constant level/intensity of smoke throughout its use, until the rod of smokable material has been entirely combusted and the intensity drops to zero.
  • the intensity of the aerosol generated by a HNB consumable tends to decline more gradually through its use, as the quantity of volatile substances (e.g. nicotine, humectant and/or flavou rant) within the aerosol-forming substrate decreases.
  • the present invention offers a means for the user to compensate for this decline in intensity during use of the HNB consumable.
  • the user may adjust the axial length of the filter element to increase the intensity again, thereby extending the operable lifetime of the HNB consumable, which in turn leads to cost savings and lower levels of waste.
  • the aerosol-forming substrate is capable of being heated to release at least one volatile compound that can form an aerosol.
  • the aerosol-forming substrate may be located at the upstream end of the consumable.
  • the terms“upstream” and“downstream” are intended to refer to the flow direction of the vapour/aerosol i.e. with the downstream end of the consumable being the mouth end or outlet where the aerosol exits the consumable for inhalation by the user.
  • the upstream end of the consumable is the opposing end to the downstream end.
  • the aerosol-forming substrate comprises at least one volatile compound that is intended to be vaporised/aerosolised and that may provide the user with a recreational and/or medicinal effect when inhaled.
