Definitions

  • the present disclosure relates to a consumable for a smoking substitute device.
  • a heat not burn consumable In particular, but not exclusively, to a heat not burn consumable. It also relates to a heat not burn system comprising a consumable and a heating element, and a device for housing the system.
  • 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.
  • a first existing implementation of the HNB approach is the IQOSTM device from Philip Morris Ltd.
  • the IQOSTM device uses a consumable, including reconstituted tobacco contained within a metallic foil and paper wrapper.
  • the consumable is a cylindrical, rod-shaped consumable designed to resemble a traditional cigarette which is inserted into a heater device.
  • the heater device has a thermally conductive heating blade 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 GloTM from British American Tobacco.
  • GloTM also uses a rod-shaped consumable similar in appearance to a traditional cigarette.
  • the consumable includes reconstituted tobacco in a paper wrapping which is heated in a 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 traditional cigarette).
  • the tobacco may contain high levels of aerosol formers (carrier), such as vegetable glycerine ("VG”) or propylene glycol ("PG").
  • VG vegetable glycerine
  • PG propylene glycol
  • Both devices also fail to conceal the residues which remain in the consumable after heating, these residues being both aesthetically unpleasing and also presenting a contamination risk to the user during removal of the consumable from the device.
  • the aerosol formers may leach from the consumable to stain and/or dampen the paper wrapping which is aesthetically unappealing and which can lead to transfer of the aerosol formers to contaminate the user.
  • an aerosol-forming article e.g. a smoking substitute article such as an HNB consumable comprising an aerosol-forming substrate having upper and lower surfaces spaced by longitudinally-extending transverse surfaces wherein at least one of the surfaces is a curved or rounded surface or comprises a curved or rounded surface portion and wherein the substrate has a non-circular transverse cross section.

  • HNB heat not burn
  • a planar heating element aligned with the width direction.
  • heating of the substrate can be effected using a heating element at a lower temperature (e.g. around 250 °C) which reduces the chances of burning of the substrate.
  • the curved surface(s) (portion(s)) reduces the number of (or eliminates) right-angled corners associated with a planar substrate having a rectangular transverse cross section. Such corners present areas of substrate that are remote from the heating element and thus prone to incomplete heating.
  • 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.

In this manner, heating of the substrate can be effected using a heating element at a lower temperature (e.g. around 250 °C) which reduces the chances of burning of the plant product.
