Definitions

  • the present invention relates generally to smoking substitute apparatuses, and smoking substitute kits which are in some way configured to deliver a flavourant to a user without the need for flavoured e-liquid, for example using printed flavourants, flavoured or scented ink, and a kit including a smoking substitute apparatus and a flavourant applicator.
  • 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.
  • 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.
  • the inhaled aerosol typically bears nicotine and/or a flavourant 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.
  • vaping in which a vaporisable liquid, typically referred to (and referred to herein) as “e-liquid”, is heated by a heating device (referred to herein as an electronic cigarette or “e-cigarette” device) to produce an aerosol vapour which is inhaled by a user.
  • e-liquid typically includes a base liquid as well as nicotine and/or a flavourant.
  • the resulting vapour therefore also typically contains nicotine and/or a flavourant.
  • the base liquid may include propylene glycol and/or vegetable glycerine.
  • a typical e-cigarette device includes a mouthpiece, a power source (typically a battery), a tank for containing e-liquid, as well as a heating device.
  • a power source typically a battery
  • a tank for containing e-liquid as well as a heating device.
  • electrical energy is supplied from the power source to the heating device, which heats the e-liquid to produce an aerosol (or "vapour") which is inhaled by a user through the mouthpiece.
  • E-cigarettes can be configured in a variety of ways.
  • there are "closed system" vaping smoking substitute systems which typically have a sealed tank and heating element. The tank is pre-filled with e-liquid and is not intended to be refilled by an end user.
  • One subset of closed system vaping smoking substitute systems include a main body which includes the power source, wherein the main body is configured to be physically and electrically coupled to a consumable including the tank and the heating element. In this way, when the tank of a consumable has been emptied, that consumable is disposed of. The main body can be reused by connecting it to a new, replacement, consumable.
  • Another subset of closed system vaping smoking substitute systems are completely disposable, and intended for one-use only.
  • vaping smoking substitute systems which typically have a tank that is configured to be refilled by a user. In this way the entire device can be used multiple times.
  • An example vaping smoking substitute system is the mybluTM e-cigarette.
  • the mybluTM e-cigarette is a closed system which includes a main body and a consumable.
  • the main body and consumable are physically and electrically coupled together by pushing the consumable into the main body.
  • the main body includes a rechargeable battery.
  • the consumable includes a mouthpiece, a sealed tank which contains e-liquid, as well as a heater, which for this device is a heating filament coiled around a portion of a wick.
  • the wick is partially immersed in the e-liquid, and conveys e-liquid from the tank to the heating filament.
  • the device is activated when a microprocessor on board the main body detects a user inhaling through the mouthpiece. When the device is activated, electrical energy is supplied from the power source to the heating device, which heats e-liquid from the tank to produce a vapour which is inhaled by a user through the mouthpiece.
  • a smoking substitute device it is desirable to deliver nicotine into the user's lungs, where it can be absorbed into the bloodstream.
  • e-liquid is heated by a heating device to produce an aerosol vapour which is inhaled by a user.
  • Many e-cigarettes also deliver flavour to the user to enhance the experience.
  • flavour compounds are contained in the e-liquid that is heated.
  • toxicology restrictions are placed on the amount of flavour that can be contained in the e-liquid, and this can result in some e-liquid flavours delivering a weak and underwhelming taste sensation to consumers in the pursuit of safety.
  • providing a flavourant as part of the e-liquid such that the flavourant is vaporised with the e-liquid, may be disadvantageous.
  • HT Heated Tobacco
  • HNB heat not burn
  • the tobacco may be leaf tobacco or reconstituted tobacco.
  • the intention is that the tobacco is heated but not burned, i.e. the tobacco does not undergo combustion.
  • the heating, as opposed to burning, of the tobacco material is believed to cause fewer, or smaller quantities, of the more harmful compounds ordinarily produced during smoking. Consequently, the HT approach may reduce the odour and/or health risks that can arise through the burning, combustion and pyrolytic degradation of tobacco.
  • a typical HT 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 components 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 the location of vaporization to an outlet of the consumable (e.g. a mouthpiece), the vapour cools and condenses to form an aerosol for inhalation by the user.
  • the aerosol may contain nicotine and/or flavour compounds.
  • the present application relates to smoking substitute apparatuses, which are configured in some way to receive a flavourant, so that the user is able to experience flavour at the same time as inhaling the flavourless e-liquid, or vapour from the heated tobacco consumable.
  • This application also relates to kits of parts including components allowing a user to apply a flavourant of choice to the outside surface of their smoking substitute apparatus, in order to achieve the same effect.
  • a first aspect of the invention accordingly, provides a smoking substitute apparatus having a flavourant-receiving portion which is configured to receive a flavourant from a flavourant applicator.
  • flavourant-receiving portion should be understood to mean a part of the smoking substitute apparatus which is adapted in some way to receive flavourant from the applicator. It will be appreciated by the skilled person that the specific features of the flavourant-receiving portion will differ depending on the type of flavourant-receiving portion. However, in preferred embodiments, the flavourant-receiving portion is located at a mouthpiece of the smoking substitute apparatus.
  • flavourant-receiving portion is located on a top surface of the smoking substitute apparatus.
  • the flavourant-receiving portion may be configured to receive a liquid flavourant, such as a scented and/or flavoured ink.
  • the flavourant-receiving portion may include a porous material which is configured to absorb a liquid flavourant.
  • the porous material may include one or more of a porous polymer, activated carbon, and wood.
  • the porous material may include a woven fabric or a non-woven fabric. Use of a porous material in this manner improves the capacity of the flavourant-receiving portion, since the liquid flavourant may be absorbed into it, rather than merely resting on the surface of the smoking substitute apparatus.
  • the liquid flavourant may be in the form of a semi-solid, a gel, a suspension, or a solid-liquid colloid.
  • the flavourant-receiving portion may be configured to receive a first flavourant layer and a second flavourant layer, wherein the second flavourant layer is located above the first flavourant layer.
  • the first flavourant layer is less viscous than the second flavourant layer.
  • the first flavourant layer may be a liquid
  • the second flavourant layer may be in the form of a semi-solid, a gel, a suspension, or a solid-liquid colloid.
  • the more viscous second flavourant layer is able to contain the less viscous first flavourant layer until the user inhales on the smoking substitute apparatus, releasing the first flavourant layer.
  • the first flavourant layer may be a different flavour from the second flavourant layer.
  • the flavourant-receiving portion may be configured to cause the liquid flavourant applied thereto to spread out.
  • the flavourant-receiving portion may be configured to promote wetting of the surface of the smoking substitute apparatus, in order to ensure coverage over a larger area of the smoking substitute apparatus. In this way, the flavourant is better able to stick of the surface of the smoking substitute apparatus, rather than settling in a large drop.
  • this spreading out effect may be achieved by the flavourant-receiving portion including a plurality of microchannels or a textured surface, e.g. sandpaper.
  • Spreading out of flavourant also increases the surface area, for improved volatilization.
  • the flavourant-receiving portion may include linear grooves, striations or a coarse membrane.
  • the flavourant-receiving portion may include a recess which is configured to receive a droplet of flavourant.
  • the recess is configured to retain the droplet therein against gravity, i.e. the recess is shaped in a manner which prevents the droplet from falling out. This may be achieved by providing a recess which is configured to retain the droplet by means of the surface tension of the liquid flavourant.
  • a portion of an inner surface of the recess may be porous or absorbent.
  • the recess is preferably cylindrical or substantially cylindrical. Alternatively, the recess may be in the form of a groove or elongate slot.
  • smoking substitute apparatus may include a plurality of flavourant-receiving portions, for example a plurality of recesses, each configured to retain a droplet of flavourant.
  • the plurality of recesses may be arranged substantially equidistantly, for example in a polka dot patter.
  • the smoking substitute apparatus may include a first flavourant-receiving portion on a first surface of the smoking substitute apparatus, and a second flavourant-receiving portion on a second surface of the smoking substitute apparatus, wherein the first surface may be opposite to the second surface.
  • the recess may have a volume between 0 and 2 ml, more preferably between 0.1 and 1 ml, and more preferably between 0.2 and 0.5 ml.
  • a second aspect of the present invention provides a smoking substitute kit, including a smoking substitute apparatus of the third aspect of the invention, and a flavourant applicator for applying a flavourant-containing element to the flavourant-receiving portion of the smoking substitute apparatus.
  • the flavourant applicator is configured to apply a liquid flavourant to the flavourant-receiving portion of the smoking substitute apparatus, to form the flavourant-containing element.
  • the liquid flavourant may be colourless, but in other embodiments, the liquid flavourant may include a flavoured or scented ink.
  • the flavourant-containing element formed by the application of the liquid flavourant may be configured to indicate visually how much flavourant is remaining in the flavourant-containing element. In this way, a user of the smoking substitute apparatus is able to identify when the flavourant has run out, and needs, e.g. to be replaced.
  • the flavourant-containing element may be configured to fade over time, wherein the extent to which the flavourant-containing element has faded provides the visual indication of the amount of flavourant is remaining in the flavourant-containing element.
  • the flavourant applicator may be in the form of a felt-tip pen (such as a "dry wipe” marker, or a permanent marker), a rollerball pen, a gel pen, or a ball point pen.

  • the dropper or pipette is preferably configured to dispense droplets having a volume between 0 and 2 ml, more preferably between 0.1 and 1 ml, and more preferably between 0.2 and 0.5 ml.
  • the flavourant applicator may include flavourant which is encapsulated in a plurality of microcapsules.
  • the flavourant may be encapsulated in an encapsulation material comprising one or more of: ethyl cellulose, polyvinyl alcohol, and sodium alginate.
  • the microcapsules are preferably configured to rupture, disintegrate or break down under the application of pressure.
  • the microcapsules may be configured to burst when they are pressed against the flavourant-receiving portion of the smoking substitute apparatus, thus releasing the flavourant onto the flavourant-receiving portion.
  • the application of friction may be used to deliver the flavourant to the flavourant-receiving portion, specifically the microcapsules may be configured to rupture, disintegrate, or break down when the flavour applicator is rubbed against the flavourant-receiving portion of the smoking substitute apparatus thereby releasing the flavourant onto the flavourant-receiving portion of the smoking substitute apparatus.
  • the flavourant applicator may include a flavourant layer and a protective layer covering the flavourant layer, and the protective layer may be configured to rupture, disintegrate or break down when the flavourant applicator is pressed or rubbed against the flavourant-receiving portion of the smoking substitute apparatus, thereby releasing the flavourant onto the flavourant-receiving portion of the smoking substitute apparatus.

  • the main body 102 may also comprise a controller that controls the supply of power from the power source to the main body electrical contacts (and thus to the filament 111). That, is the controller may be configured to control a voltage applied across the main body electrical contacts, and thus the voltage applied across the filament 111. In this way, the filament 111 may only be heated under certain conditions (e.g. during a puff and/or only when the system is in an active state).
  • the main body 102 may include a puff sensor (not shown) that is configured to detect a puff (i.e. inhalation).
  • the puff sensor may be operatively connected to the controller so as to be able to provide a signal, to the controller, which is indicative of a puff state (i.e. puffing or not puffing).
  • the puff sensor may, for example, be in the form of a pressure sensor or an acoustic sensor.
  • the main body 102 and consumable 103 may comprise a further interface which may, for example, be in the form of an RFID reader, a barcode or QR code reader.
  • This interface may be able to identify a characteristic (e.g. a type) of a consumable 103 engaged with the main body 102.
  • the consumable 103 may include any one or more of an RFID chip, a barcode or QR code, or memory within which is an identifier and which can be interrogated via the interface.
  • FIGS 2A and 2B illustrate a smoking substitute system the form of a heated tobacco (HT) system 201.
  • the system 201 comprises an HT device 202 and an aerosol-forming article in the form of a HT consumable 203.
  • the consumable 203 is configured to engage the device 202 by way of an interference fit.
  • Figure 2A shows the device 202 and the consumable 203 in an engaged state
  • Figure 2B shows the device 202 and the consumable 203 in a disengaged state.
  • the consumable 203 generally resembles a cigarette.
  • the consumable 202 has a generally cylindrical form with a diameter of approximately 7 mm and an axial length of approximately 70 mm.
  • the consumable 203 comprises an outer wrapping layer 213 defining a passage 206 extending between openings at opposing ends of the consumable 203.
  • the passage comprises an upstream end (and opening) 207 at the end of the consumable 203 that engages with the device 202, and a downstream end (and opening) 208 at an opposing end of the consumable 203 that projects from the device 202 (when engaged) and defines a mouth end 209 of the system 201.
  • a user can inhale (i.e. take a puff) via the mouth end 209 so as to draw air through the passage 206, and so as to form an airstream in a direction from the upstream end 207 to the downstream end 208 of the passage 206.
  • the consumable 203 comprises an aerosol former in the form of an aerosol-forming substrate 204 that is disposed at the upstream end 207 of the passage 206.
  • the consumable 203 further comprises an upstream filter 214 adjacent the aerosol-forming substrate 204, a terminal filter 215 at the downstream end 208, and a spacer 216 interposed between the terminal 215 and upstream 214 filters.
  • the aerosol forming substrate 204 comprises tobacco material that may, for example, include any suitable parts of the tobacco plant (e.g. leaves, stems, roots, bark, seeds and flowers).
  • the aerosol forming substrate 204 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.
  • the aerosol-forming substrate 204 may further comprise one or more additives.
  • such additives may be in the form of humectants (e.g. propylene glycol and/or vegetable glycerine), flavourants, fillers, aqueous/non-aqueous solvents and/or binders.
  • the device comprises a heating element 211 that projects into the aerosol-forming substrate 204 when the consumable 203 is engaged with the device 202.
  • This heating element 211 is electrically connected to a power supply (not shown) of the device 202 and, when activated, heats the aerosol-forming substrate 204 such that vapour is released from the aerosol-forming substrate 204.
  • a user inhales via the mouth end 209, air is drawn through the heated aerosol-forming substrate 204 and the vapour becomes entrained in the resultant airflow.
  • the vapour flows from the aerosol-forming substrate 204 to the downstream end 208 of the passage 206 (through the filters 214, 215 and the spacer 216), it condenses into an aerosol and the aerosol is inhaled by the user.
  • the consumable 203 when engaged, the consumable 203 is received in a cavity 217 formed in a housing 218 of the device 202. Whilst not shown in the figures, the housing 218 accommodates (in addition to the abovementioned power supply) a controller for controlling power supply to the heating element 211. Control of the heating element 211 may be performed in response to a user input (e.g. via a button 219 disposed on the housing 218) and/or a signal received from a puff sensor (configured to indicate a puff state).
  • FIG. 3 shows an end of an e-cigarette system 301, which may be as shown in Figs. 1A to 1C .
  • E-cigarette system 301 includes a recess 305 which is located on the top surface 307 of the mouthpiece end 309 of the portion of the consumable 311 which is visible when the consumable is engaged with the main body 313.
  • the recess 305 which is shaped as a shallow cylinder, and is configured to retain liquid flavourant which is stored therein against gravity, e.g. by exploiting the surface tension of the liquid flavourant (not shown).
  • the geometry of the recess 305 may be such that it is small enough so as only to hold enough liquid flavourant for a limited amount of vaping, e.g. 3 three-second inhalations, before the liquid flavourant is completely volatilized.
  • a user is able to switch flavourants at leisure, because each individual portion supplied to the recess 305 does not last long before fully evaporating.
  • Fig. 4 shows an example of a smoking substitute kit 450 according to the fourth aspect of the invention.
  • the smoking substitute kit 450 includes a consumable 452 having a flavourant-receiving portion 454 at its upper end, and a flavourant applicator in the form of pen 456.
  • a user is able to apply liquid flavourant in the form of flavoured or scented ink by using the pen 456.
  • the flavourant-receiving portion 454 is adapted so that the ink from the pen 456 is able to stick to the surface of the consumable 452.
  • Fig. 5 shows another example of a smoking substitute kit 500 according to the fourth aspect of the invention.
  • the smoking substitute kit 500 includes smoking substitute apparatus 502 and flavourant applicator 504.
  • the flavourant applicator 504 in Fig. 5 is spherical and includes liquid flavourant which is encapsulated in microcapsules which are configured to rupture and deposit the flavourant onto the surface of the smoking substitute apparatus 502 when the flavourant applicator 504 is rubbed or scratched, or under the application of heat. This works using the same mechanism as "scratch and sniff".
