Definitions

  • the present invention relates to a heat not burn consumable for a smoking substitute device.
  • a heat not burn consumable comprising tobacco.
  • 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.
  • Such substitute devices can form part of nicotine replacement therapies aimed at people who wish to stop smoking and overcome a dependence on nicotine.
  • Substitute devices may comprise electronic systems that permit a user to simulate the act of smoking by producing an aerosol that is drawn into the lungs through the mouth (inhaled) and then exhaled.
  • the inhaled aerosol typically bears nicotine and/or flavourings without, or with fewer of, the odour and health risks associated with traditional smoking.
  • substitute devices and 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 tobacco products.
  • a substitute approach corresponds to the manner in which the substitute system operates for a user.
  • HNB heat not burn
  • an HNB system includes a heating device and consumable.
  • the consumable includes the tobacco material.
  • the consumable is configured for engagement with the heating device.
  • heat is imparted to the tobacco material from a heat source of the heating device.
  • Air flow through the tobacco material causes moisture in the tobacco material to be released as vapour.
  • a first vapour may thus be formed from a carrier in the tobacco material, for example polyglycol (PG) or vegetable glycerine (VG).
  • PG polyglycol
  • VG vegetable glycerine
  • volatile compounds may also be released from the tobacco as a second vapour.
  • the vapour(s) released from the tobacco are entrained in the airflow drawn through the tobacco.
  • HNB 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.
  • a first existing implementation of the HNB approach is the IQOS TM device from Philip Morris Ltd.
  • the IQOS TM device uses a consumable element, including reconstituted tobacco located in a wrapper.
  • the consumable includes a holder incorporating a mouthpiece.
  • the consumable may be inserted into a heater device.
  • the thermal heater device has a thermally conductive heating knife which penetrates the reconstituted tobacco of the consumable, when the consumable is inserted into the heating device. Activation of the heating device heats the heating element, which, in turn, heats the tobacco in the consumable.
  • the heating of the tobacco causes it to release nicotine vapour and flavours which may be drawn through the mouthpiece by the user through inhalation.
  • a second existing implementation of the HNB approach is the device known as "Glo" TM from British American Tobacco p.l.c .. Glo TM comprises a relatively thin consumable.
  • the consumable includes leaf tobacco which is heated in a heating device. When the consumable is placed in the heating device, the tobacco is surrounded by a heating element. Activation of the heating device heats the heating element, which, in turn, heats the tobacco in the consumable. The heating of the tobacco causes it to release nicotine vapour and flavours which may be drawn through the consumable by the user through inhalation.
  • the tobacco when heated by the heating device, is configured to produce vapour when heated rather than when burned (as in a smoking apparatus, e.g. a cigarette).
  • the tobacco may contain high levels of aerosol formers (carrier), such as vegetable glycerine ("VG”) or propylene glycol ("PG").
  • the present invention provides a heat not burn consumable comprising: a tubular vapour generating member defining a channel therethrough, wherein at least an active portion of the vapour generating member is configured to be heated by a heater to produce vapour, wherein: the tubular vapour generating member has an inlet to the channel at a first end of the consumable, the first end of the consumable being for cooperation with a heating device.
  • Such a heat not burn consumable may be combined with any one or more features from the following disclosure.
  • a heat not burn consumable according to claim 1.
  • the heat not burn consumable comprises a tubular vapour generating member defining a channel therethrough, wherein at least an active portion of the vapour generating member is configured to produce vapour when heated by a heater, wherein the active portion comprises an active substrate formed from a rolled sheet and including an aerosol former and an active substance; the vapour generating member has an overall length which is greater than 50% of a total length of the consumable; and the active substrate of the active portion includes between 0.0002 milligrams and 0.02 milligrams of active substance per milligram of said active substrate.
  • a total mass of an active substrate comprised in the active portion is greater than 100mg and less than 1000mg.
  • the consumable has a total longitudinal length less than or equal to 100 mm and/or greater than or equal to 50 mm.
  • the vapour generating member includes an active substance, and wherein the active substance includes nicotine.
  • the invention includes the combination of the aspects and preferred features described except where such a combination is clearly impermissible or expressly avoided.
  • the present invention is directed to an HNB consumable.
  • the HNB consumable forms a constituent element of an HNB system.
  • An HNB consumable according to the present invention is configured for use with a heating device.
  • an HNB consumable and a heating device form an HNB system.
  • the HNB consumable may be configured for engagement with the heating device.

  • the consumable 1 forms an elongate airflow passage 2 which extends from a first end 3 to a second end 4 of the consumable 1.
  • the first end 3 of the consumable 1 may be configured for interaction with a heating device.
  • the second end 4 of the consumable 1 may be configured to form a mouthpiece.
  • the user may directly engage the second end 4 with their mouth, or a mouthpiece component may be attached to the second end, and then, in turn, the user may engage the mouthpiece component.
  • a mouthpiece component does not form part of the present invention.
  • the first end 3 of the consumable 1 may be considered to represent a so-called "upstream” end of the consumable 1
  • the second end 4 of the consumable 1 may be considered to represent a so-called “downstream” end of the consumable 1, in a flow-series sense with respect to the direction of airflow through the consumable 1 along the airflow passage 2 during use.
  • the consumable has inlet 5 at the first end 3 and an outlet 6 at the second, opposite end 4.
  • the user draws on the second end 4, which causes airflow into the consumable 1 at the inlet 5, through the consumable 1 along the airflow passage 2, to the outlet 6.
  • VGM vapour generating member 7
  • the VGM 7 defines a channel therethrough. The channel through the VGM 7 forms a portion of the airflow passage 2 through the consumable 1.

  • the supporting tube 8 defines a channel therethrough.
  • the channel through the supporting tube 8 forms a portion of the airflow passage 2 through the consumable 1.

  • the mixing zone is located between the VGM 7 and the outlet 6.
  • the vapours from the VGM 7 mix with each other, either from the VGM 7, or from other sources.
  • the supporting tube 7 may include perforations through its sidewall. The perforations may allow an airflow into the mixing zone through the perforations.
  • the supporting tube 8 may also form a cooling zone in the channel therethrough. In the cooling zone, the vapours from the VGM 7 cool, which may result is condensation from vapour to an aerosol for user inhalation.
  • the channel formed through the VGM 7 may be generally contiguous with the channel through the supporting tube 8.
  • the internal transverse cross sectional shape of the supporting tube 8 may be of the same size and shape as the internal transverse cross-sectional shape of the VGM 7.
