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.
  • an aerosol-forming article e.g. a smoking substitute article such as an HNB consumable having a hollow bore filter at its axial downstream end.
  • an aerosol-forming article e.g. a smoking substitute article such as an HNB consumable
  • an aerosol-forming substrate wherein the article further comprises a terminal filter element at the axial downstream of end of the article, the terminal filter element being a hollow bore filter element; and one or more of an upstream filter element, an upstream aerosolcooling element and an upstream spacer element.
  • the terminal filter element allows delivery of an aerosol (through the hollow bore) to the user’s mouth that remains rich in volatile compound and visible vapour.
  • the terminal hollow bore filter also reduces the resistance to draw (RTD) which provides a more comfortable smoking experience for the user.
  • RTD resistance to draw
  • the terminal hollow bore filter acts as an airflow restrictor which contributes to a vapour mixing effect by increasing the local airflow speed within the bore.
  • the upstream filter element i.e. upstream from the terminal filter element but downstream from the aerosol-forming substrate
  • the upstream cooling element acts to cool the vapour prior to user inhalation thus increasing comfort for the user.
  • the spacer element acts to cool and mix the vapour generated from the aerosol-forming substrate.
  • 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 article/consumable being the mouth end or outlet where the aerosol exits the article/consumable for inhalation by the user.
  • the upstream end of the article/consumable is the opposing end to the downstream end.
  • the internal diameter of the bore in the terminal filter element may be between 1 and 3 mm.
  • the internal dimeter of the bore may be substantially about 1 mm or 2mm or 3mm.
  • the upstream filter element may also be a hollow bore filter element which will further increase the volatile compound concentration in the aerosol, further reduce the resistance to draw and further increase vapour mixing.
  • the internal diameter of the bore in the upstream filter element may be greater than the internal diameter of the bore in the terminal filter element.
  • the internal dimeter of the bore may be substantially about 2mm or 3mm or 4mm i.e. between 2 and 4 mm.
  • the internal bore diameter of the upstream filter element is around 3mm and the internal diameter of the terminal filter element is around 2mm.
  • the upstream and/or terminal filter element may be comprised of cellulose acetate or polypropylene tow.
  • the upstream and/or terminal filter element may be comprised of activated charcoal.
  • the upstream and/or terminal filter element may be comprised of paper.
  • the density of the material forming the terminal filter element is increased e.g. is greater than the density of the material forming the upstream filter element in order to force the air flow through the bore in the terminal filter element.
  • the terminal bore filter may be formed of substantially solid/non-porous material.
  • the or each filter element may be circumscribed with a plug wrap e.g. a paper plug wrap.
  • the upstream filter element and terminal filter element may be axially spaced for example, the upstream filter element and the terminal filter element may be spaced by the cooling element and/or the spacer element.
  • the aerosol-cooling element is adapted to cool the aerosol generated from the aerosol-forming substrate (by heat exchange) before being inhaled by the user.
  • the aerosol-cooling element may be axially adjacent the terminal filter element.
  • the aerosol-cooling element may be axially adjacent the upstream filter element.
  • the aerosol-cooling element may be formed of a plastics material selected from the group consisting of polylactic acid (PLA), polyvinyl chloride (PVC), polyethylene (PE) and polyethylene terephthalate (PET).
  • the aerosol-cooling element may be formed of a crimped/gathered sheet of material to form a structure having a high surface area with a plurality of longitudinal channels to maximise heat exchange and cooling of the aerosol.
  • the spacer element that defines a space or cavity or chamber, for example, a space or cavity between the two filters.
  • the spacer acts to allow both cooling and mixing of the aerosol.
  • the spacer element may be axially adjacent the terminal filter element.
  • the spacer element may be axially adjacent the upstream filter element.
  • the spacer element may be a tubular element e.g. a cardboard tube.
  • the spacer element may have an external diameter of between 5 and 10mm e.g. between 6 and 9mm or 6 and 8mm e.g. around 7 mm. It may have an axial length of between 10 and 15mm e.g. between 12 and 14 mm or 13 and 14mm e.g. around 14mm.
