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.

- the tipping layer 7 i.e. circumscribing the plug wrap joining the filter portions 5a, 5b.
- FIG. 2 shows a second embodiment of a consumable T which is the same as that shown in Figure 1 except that the downstream filter portion 5b of the terminal filter element 5 comprises a crushable capsule
- the capsule 8 (crush-ball) having a shell wall containing a liquid menthol or cherry or vanilla flavourant.
- the capsule 8 is spherical and has a diameter of 3.5 mm. It is positioned within the axial centre of the downstream filter portion 5b of the terminal filter element 5.
- Figure 3 shows a third embodiment of a consumable 1” which is the same as the first embodiment except that the upstream filter portion 5a is a solid filter element and the downstream filter portion 5b is a hollow bore filter element (i.e. the arrangement is reversed from the previously described embodiments). Furthermore, the wrapping layer 3 does not completely circumscribe the cardboard tube spacer 6 such that there is an annular gap 9 between the tipping layer 7 and the cardboard tube spacer 6 downstream of the end of the wrapping layer 3.
- Figure 4 shows the first embodiment inserted into an HNB device 1 1 comprising a rod-shaped heating element 20.
- the heating element 20 projects into a cavity 12 within the main body 13 of the device.
- the consumable 1 is inserted into the cavity 12 of the main body 13 of the device 1 1 such that the heating rod 20 penetrates the aerosol-forming substrate 2.
- Heating of the reconstituted tobacco in the aerosolforming substrate 2 is effected by powering the heating element (e.g. with a rechargeable battery (not shown)).
- the heating element e.g. with a rechargeable battery (not shown)
- moisture and volatile compound e.g. nicotine
- the humectant are released as a vapour and entrained within an airflow generated by inhalation by the user at the terminal filter element 5.
- the vapour cools within the upstream filter element 4 and the cardboard tube spacer 6, it condenses to form an aerosol containing the volatile compounds for inhalation by the user.
