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 paperthat 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.
  • an aerosol-forming article e.g. a smoking substitute article such as an HNB consumable comprising a liquid-containing capsule that can be ruptured mechanically by a heater element.
  • the present invention provides an aerosol-forming article (e.g. a smoking substitute article such as an HNB consumable) comprising an aerosol-forming substrate wherein the article further comprises a liquid pod enclosed within the aerosol-forming substrate and adapted to be ruptured mechanically upon coupling with a heating element.
  • an aerosol-forming article e.g. a smoking substitute article such as an HNB consumable
  • the article further comprises a liquid pod enclosed within the aerosol-forming substrate and adapted to be ruptured mechanically upon coupling with a heating element.
  • the liquid within the liquid pod can be released without user intervention e.g. without the user having to locate and crush the liquid pod.
  • the liquid can be released simply upon coupling of the consumable with the heating element.
  • the liquid can wick into the surrounding aerosol-forming substrate so that the liquid can modify the vapour released from the substrate and thus tailor/enhance the user experience.
  • 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 liquid pod may be embedded within the aerosol-forming substrate or may be housed within a cavity in the aerosol-forming substrate.
  • the liquid pod may have an outer shell which may be solid/rigid.
  • the outer shell may be crushable, breakable or penetrable by the heating element.
  • the liquid pod may be substantially spherical. Liquid pods typically known as“crush balls” can be used.
  • the liquid pod may carry a liquid vapour modifier.
  • the vapour modifier may comprise one or more humectant or and/or a flavourant.
  • Suitable humectants include polyhydric alcohols (e.g. propylene glycol (PG), triethylene glycol, 1 ,2-butane diol and vegetable glycerine (VG)) and their esters (e.g. glycerol mono-, di- or tri-acetate). Inclusion of a humectant in the liquid pod within the cavity allows the generation of an increased amount of visible vapour potentially at lower temperatures.
  • the flavourant may include menthol, liquorice, chocolate, fruit flavour (including e.g. citrus, cherry etc.), vanilla, spice (e.g. ginger, cinnamon) and tobacco flavour.
  • the liquid pod will be spaced from the upstream end of the aerosol-forming substrate by a distance that is less than the penetration depth of the heating element within the aerosol-forming substrate. This may mean that the liquid pod is closer to the upstream axial end of the aerosol-forming substrate than the downstream end.
  • the penetration depth may be around 12mm and so the liquid pod may be spaced from the upstream end ofthe aerosol-forming substrate by a distance of less than 12mm e.g. by a distance of 10mm or less e.g. 9 or 8 mm or less e.g. by a distance of 7 or 6mm or less. It may be spaced from the upstream axial end of the aerosol-forming substrate by an amount of 1 or 2mm or more e.g. by an amount of 3 or 4 or 5mm or more. For example, it may be spaced form the axial upstream end by an amount between 1 and 12mm e.g. between 2 and 10 mm, such as between 3 and 8 mm, for example between 4 and 7 mm or between 5 and 6 mm.
  • 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 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.
