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 comprising two different aerosol-forming materials.
- the present invention provides an aerosol-forming article e.g. a smoking substitute article such as an HNB consumable comprising an aerosol-forming substrate wherein the aerosol-forming substrate comprises at least one discrete region of a first aerosol-forming material within a matrix of a second aerosol-forming material.
- a smoking substitute article such as an HNB consumable
- the aerosol-forming substrate comprises at least one discrete region of a first aerosol-forming material within a matrix of a second aerosol-forming material.
- the user experience can be tailored and thereby enhanced.
- the two different aerosol-forming materials can be selected such that during the smoking of a single article/consumable the user is exposed to a mix of two vapours/aerosols having different properties e.g. different flavours and/or different strengths of volatile compounds.
- references to “discrete region(s)” of the first aerosol-forming material means that the concentration/dispersion of the first aerosol-forming material within the second aerosol-forming material is not uniform. This is in contrast to substrates formed from homogenised blends of two different types of aerosol-forming materials. Instead of being homogenised, the first aerosol-forming material is concentrated into one or more discrete regions within the second aerosol-forming material matrix.
- the plurality of discrete regions of first aerosol-forming material may be evenly spaced within the matrix of the second aerosol-forming material. At least some and possibly all of the plurality of discrete regions of first aerosol-forming material may be entirely embedded within i.e. entirely surrounded by the matrix of the second aerosol-forming material.
- 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 article/consumable.
- 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.
- each of the first and second aerosol-forming materials comprises at least one volatile compound that is intended to be vaporised/aerosolised and that may provide the user with a recreational and/or medicinal effect when inhaled.
- Suitable chemical and/or physiologically active volatile compounds include the group consisting of: nicotine, cocaine, caffeine, opiates and opoids, cathine and cathinone, kavalactones, mysticin, beta-carboline alkaloids, salvinorin A together with any combinations, functional equivalents to, and/or synthetic alternatives of the foregoing.
- the first and/or second aerosol-forming material may comprise plant material.
- the plant material may comprise least one plant material selected from the list including Amaranthus dubius, Arctostaphylos uva- ursi (Bearberry), Argemone mexicana, Arnica, Artemisia vulgaris, Yellow Tees, Galea zacatechichi, Canavalia maritima (Baybean), Cecropia mexicana (Guamura), Oestrum noctumum, Cynoglossum virginianum (wild comfrey), Cytisus scoparius, Damiana, Entada rheedii, Eschscholzia califomica (California Poppy), Fittonia albivenis, Hippobroma longi flora, Humulus japonica (Japanese Hops), Humulus lupulus (Hops), Lactuca virosa (Lettuce Opium), Laggera

- Each pellet/chip/granule may form one of the plurality of discrete regions within the matrix of the first aerosol-forming material.
- each pellet/chip/granule is of macroscopic size.
- Extruded tobacco can produced by forming a liquid mixture of powered tobacco and a binding agent such as a gum (e.g. xanthan, guar, arabic and/or locust bean gum). The liquid mixture is heated and then extruded through a die. The extrudate is dried and then may be subsequently cut into pellets, chips or granules.
