Definitions

  • the present invention relates to a mouthpiece for a smoking substitute apparatus, and to a flavourant dispenser for applying flavourant to the mouthpiece.
  • 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 prefilled 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.
  • 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 vapourisation 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.
  • 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.
  • the present invention relates to a mouthpiece for a smoking substitute apparatus that is arranged to absorb a flavourant applied thereto.
  • flavourant absorbed by the mouthpiece may produce a flavour for the user.
  • flavour may be delivered to the user via flavourant on the mouthpiece, rather than through a flavourant contained in an aerosol-former (e.g. e-liquid or tobacco material) of the of the smoking substitute apparatus.
  • an aerosol-former e.g. e-liquid or tobacco material
  • a flavourant may be applied to the mouthpiece when the user wishes to experience flavour.
  • the user may also apply an amount of flavourant to the mouthpiece according to their taste, e.g. depending on whether they want to experience a strong flavour or not.
  • Flavourants having different flavours may be applied to the mouthpiece, so that the user may experience different flavours, without having to otherwise modify the smoking substitute apparatus. This may improve a versatility of the smoking substitute apparatus.
  • a mouthpiece for a smoking substitute apparatus comprising an outlet for conveying an aerosol generated by the smoking substitute apparatus to a user, wherein the mouthpiece is configured to absorb a flavourant applied to a surface of the mouthpiece.
  • the mouthpiece may include a material or structure thereon for absorbing flavourant applied to the surface of the mouthpiece.
  • flavourant applied to the mouthpiece may be absorbed by the mouthpiece, so that flavourant may be delivered to a user when they put the mouthpiece in their mouth.
  • the outlet may serve to convey an aerosol from the smoking substitute apparatus to the user, when the mouthpiece is assembled with the smoking substitute apparatus.
  • the outlet may be arranged such that, when the mouthpiece is assembled with the smoking substitute apparatus, the outlet is in fluid communication with an aerosol-conveying passage in the smoking substitute apparatus.
  • the mouthpiece may be a part or component of the smoking substitute apparatus, e.g. it may be an integral part of the smoking substitute apparatus.
  • the mouthpiece may be removably mountable on the smoking substitute apparatus or a component thereof.
  • the mouthpiece may include a textured surface for absorbing the flavourant applied to the surface of the mouthpiece. This may enable the mouthpiece to efficiently absorb flavourant applied thereto.
  • the textured surface may for example be an area of the mouthpiece having an increased roughness compared to the rest of the mouthpiece. A surface having a high roughness may facilitate retaining flavourant on the mouthpiece.
  • the textured surface may be produced by a applying an abrasive (e.g. a D grade sand paper) to a surface of the mouthpiece to increase the roughness of the surface of the mouthpiece.
  • a roughness of the surface of the mouthpiece may be increased by applying spark erosion and/or electrical discharge machining (EDM) techniques to the surface of the mouthpiece.
  • EDM electrical discharge machining
  • the mouthpiece may also include features thereon which are arranged to retain flavourant, e.g. indents in the surface of the mouthpiece, and/or embossed features.
  • Such features may be integrally formed with the mouthpiece, e.g. they may be moulded as part of the mouthpiece where the mouthpiece is a moulded piece of plastic.
  • a surface of the mouthpiece includes a plurality of channels formed therein for receiving the flavourant applied to the surface of the mouthpiece.
  • the channels may, for example, be formed as grooves in the surface of the mouthpiece.
  • the channels may be arranged to retain a liquid flavourant via capillary action of the liquid flavourant in the channels.
  • the plurality of channels may be arranged to distribute a liquid flavourant applied to the mouthpiece across a surface of the mouthpiece. For example, a liquid flavourant applied to the mouthpiece may be drawn into the channels and wick along the channels through capillary action, so that is distributed over a surface of the mouthpiece. This may enable the flavourant to be distributed over an area of the mouthpiece, which may enhance flavour delivery to the user, e.g. as flavourant may be delivered to the user over a wider area.
  • the mouthpiece may include an absorbent material for absorbing the flavourant applied to the surface of the mouthpiece.
  • the absorbent material may be a porous material.
  • flavourant applied to the mouthpiece may be absorbed by the absorbent material on the mouthpiece. This may enable the mouthpiece to absorb a larger amount of flavourant, so that the mouthpiece may deliver flavourant to the user for a longer period of time.
  • Use of an absorbent material on the mouthpiece may be particularly beneficial where the flavourant is a liquid flavourant. However, it may also be useful with a flavourant in the form of a powder, a particles of the flavourant powder may enter pores in the absorbent material.
  • the absorbent material may be a cloth material, or a sponge-like material.
  • the absorbent material may be a porous plastic. This may facilitate cleaning of the mouthpiece. This may also facilitate making of the mouthpiece, as the porous plastic may be formed into a mouthpiece using a moulding technique. As an example, porous plastics manufactured by Porex corporation may be used.

  • the mouthpiece may be removably mounted on the smoking substitute apparatus.
  • the mouthpiece may be integrally formed as part of the smoking substitute apparatus.
  • the smoking substitute apparatus may be in the form of a consumable.

  • the smoking substitute apparatus may be a non-consumable apparatus (e.g. that is in the form of an open smoking substitute system).
  • an aerosol former e.g. e-liquid
  • the smoking substitute apparatus may be replenished by re-filling e.g. a reservoir of the smoking substitute apparatus with the aerosol former (rather than replacing a consumable component of the apparatus).
  • the smoking substitute apparatus may alternatively form part of a main body for engagement with the smoking substitute apparatus (i.e. when the smoking substitute apparatus is in the form of a consumable).
  • the main body and the consumable may be configured to be physically coupled together.
  • the consumable may be at least partially received in a recess of the main body, such that there is an interference fit between the main body and the consumable.
