Definitions

  • the present disclosure relates to a consumable for use in a smoking substitute system and particularly, 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.
  • CN 108185517 A discloses a cigarette for heating a non-combustible tobacco.
  • the cigarette comprises a reversal counter-sunk filter stick, a first hollow filter stick, a second hollow filter stick and a tobacco stick, wherein the reversal counter-sunk filter stick comprises a filter section and a hollow section.
  • CN 107772530 A discloses a composite cigarette filter unit which has a hollow-bore portion where the inside surface of the bore is coated with flavour-containing particles.
  • WO 2015/181949 A1 discloses a smoking article having a filter attached thereto, which enables a tobacco flavour imparted by tobacco shreds and a taste sense stimulant component to be experienced separately.
  • the smoking article has a filter attached thereto comprises a tobacco rod which contains tobacco shreds, a filter which is connected to one end side of the tobacco rod, and a taste sense stimulating material which is arranged in the filter.
  • US 2015/027454 A1 discloses an electronic smoking article that includes a liquid aerosol formulation, a heater operable to at least partially volatilize the liquid aerosol formulation and form an aerosol, and a tubular filter segment downstream of the heater.
  • the tubular filter segment is operable to selectively filter aerosol particles and vapours from the aerosol.
  • US 7578298 B2 discloses a flavour capsule for enhanced flavour delivery in cigarettes.
  • the capsule is provided at a filter section of the cigarette.
  • the capsule is subjected to an external force, such as squeezing, by a smoker prior to or during smoking of the cigarette in order to release at least a portion of the additive material from the one or more capsules and expose the additive material to mainstream smoke passing through the filter.
  • US 2014/305448 A1 discloses an aerosol-generating article.
  • the article includes an aerosol-forming substrate, a support element located immediately downstream of the aerosol-forming substrate, an aerosol-cooling element located downstream of the support element, and an outer wrapper circumscribing the aerosol-forming substrate, the support element and the aerosol-cooling element.
