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.
  • an aerosol-forming article e.g. a smoking substitute article such as an HNB consumable comprising a phase change material.
  • an aerosol-forming article e.g. a smoking substitute article such as an HNB consumable
  • cooling element comprising a phase change material
  • the phase change material may be capable of storing and releasing energy during phase changes.
  • the phase change material may be a solid-liquid phase change material, whereby when the phase change material is heated, it melts from a solid to a liquid and stores the thermal energy. Heat may be transferred from vapour (passing through the cooling element) to the phase change material of the cooling element. This transfer of heat may result in cooling of the vapour, which may facilitate condensation of the vapour so as to form an aerosol.
  • the phase change material remains at a generally consistent temperature, which may allow a large amount of heat to be transferred (due to a temperature differential between the vapour and the phase change material) from the vapour to the phase change material.
  • a cooling element comprising phase change material may, in some cases, provide increased cooling of vapour passing through it.
  • the phase change material may be an organic phase change material.
  • the phase change material may, for example, be paraffin (CnH2n+2) based e.g. paraffin with 14 to 34 carbons e.g. 20 carbons (icosane/eicosane).
  • the phase change material may have a melting point of between 20°C and 40°C or e.g. between 25°C and 35°C, or between 25°C and 31 °C.
  • the phase change material may have a melting point at a temperature that is close to room temperature, such that heat from vapour (that may be hotter than room temperature) passing across the cooling element is transferred to the phase change material (which stores the heat as latent heat during the phase change).
  • the cooling element may comprise a plurality of phase change beads.
  • the phase change beads may comprise the phase change material.
  • each phase change bead may comprise a shell enclosing a core formed of the phase change material.
  • the shell may be formed of glass or plastics material.

  • the distribution of the phase change material/beads in the body may be a substantially even distribution, or the phase change material/beads may be localised to particular regions of the body. For example, there may be a concentration of phase change material/beads in regions of the body that are hotter during use of the aerosol-forming article.
  • the cylindrical body may have an axial bore extending therethrough and the phase change material/beads maybe localised proximal the bore.
  • the cylindrical body may comprise a matrix of fibrous, granular, sheet or solid plastics material.
  • the plastics material may comprise one or more of viscose, cellulose, polyester, polyacrylonitrile, polylactic acid, polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET).
  • PVC polyvinyl chloride
  • PE polyethylene
  • PP polypropylene
  • PET polyethylene terephthalate
  • the fibrous plastics material may be selected from viscose, cellulose, polyester, acrylic or polylactic acid fibres.
  • the fibres of the fibrous material may be randomly oriented within the cylindrical body.
  • the fibres of the fibrous material may be oriented in the same direction (e.g. the longitudinal direction) within the cylindrical body.
  • the fibrous material may be in the form of a fibrous sheet.
  • the sheet may be folded (or e.g. crimped, rolled, etc.) so as to form the substantially cylindrical body.
  • the sheet may define a plurality of channels extending through the cooling element.
  • the sheet may be sprayed or coated with the phase change material prior to folding/crimping or rolling so that the phase change material is dispersed within the resulting cylindrical body.
