Definitions

  • the present invention relates to an aerosol delivery component and system, and particularly, although not exclusively, to an aerosol delivery component/system configured to selectively deliver either a single aerosol or a combined first and second aerosol.
  • an aerosol delivery device is a smoking-substitute system, which is an electronic system that permits the user to simulate the act of smoking by producing an aerosol or vapour that is drawn into the lungs through the mouth and then exhaled.
  • the inhaled aerosol or vapour typically bears nicotine and/or other flavourings without the odour and health risks associated with traditional smoking and tobacco products.
  • the user experiences a similar satisfaction and physical sensation to those experienced from a traditional smoking or tobacco product, and exhales an aerosol or vapour of similar appearance to the smoke exhaled when using such traditional smoking or tobacco products.
  • a smoking substitute system is the so-called “vaping” approach, in which a vaporisable liquid, typically referred to (and referred to herein) as “e-liquid", is heated by a heating element to produce an aerosol/vapour which is inhaled by a user.
  • the e-liquid typically includes a base liquid as well as nicotine and/or flavourings.
  • the resulting vapour therefore also typically contains nicotine and/or flavourings.
  • the base liquid may include propylene glycol and/or vegetable glycerine.
  • a typical vaping smoking substitute system includes a mouthpiece, a power source (typically a battery), a tank for containing e-liquid, as well as a heating element.
  • a power source typically a battery
  • a tank for containing e-liquid as well as a heating element.
  • electrical energy is supplied from the power source to the heating element, which heats the e-liquid to produce an aerosol (or "vapour") which is inhaled by a user through the mouthpiece.
  • Vaping smoking substitute systems 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 device which includes the power source, wherein the device is configured to be physically and electrically coupled to a consumable including the tank and the heating element.
  • the consumable may also be referred to as a cartomizer. In this way, when the tank of a consumable has been emptied, the consumable is disposed of. The device 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 system can be used multiple times.
  • An example vaping smoking substitute system is the myblu ® system.
  • the myblu ® system is a closed system which includes a device and a consumable.
  • the device and consumable are physically and electrically coupled together by pushing the consumable into the device.
  • the device includes a rechargeable battery.
  • the consumable includes a mouthpiece, a sealed tank which contains e-liquid, as well as a heating element, which for this system 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 device detects a user inhaling through the mouthpiece. When the system is activated, electrical energy is supplied from the power source to the heating element, which heats e-liquid from the tank to produce a vapour which is inhaled by a user through the mouthpiece.
  • a smoking substitute system 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 element 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. Heating of the flavour compounds may be undesirable as the flavour compounds are inhaled into the user's lungs.
  • Toxicology restrictions are placed on the amount of flavour that can be contained in the e-liquid. This can result in some e-liquid flavours delivering a weak and underwhelming taste sensation to consumers in the pursuit of safety.

  • the consumable component 303 includes an upstream component inlet opening 306 and a downstream aperture 307 of the mouthpiece portion 309. In other examples, a plurality of inlets openings are included. Between, and fluidly connecting, the component inlet opening 306 and the aperture 307 there is a first flow path 401 (partly shown in Figure 5A ) comprising (in a downstream flow direction) a vaporising chamber 325 of the cartomizer portion 301, a vapour outlet channel 323 (also within the cartomizer portion 301), a downstream flow passage 321 of the flavour pod portion 302 and an aerosol generating portion 322 of the flavour pod portion 302.

  • the flavour pod portion 302 of the consumable component 303 includes a liquid transfer element 315.
  • This liquid transfer element 315 acts as a passive aerosol generator (i.e. an aerosol generator which does not use heat to form the aerosol), and is formed of a porous material.
  • the liquid transfer element 315 comprises a conveying portion 317 and an aerosol generating portion 322, which is located in the first flow path 401.
  • the aerosol generating portion 322 is a porous nib.
  • a storage chamber 316 (defined by a tank 318) for storing a first aerosol precursor (i.e. a liquid comprising a flavourant) is fluidly connected to the liquid transfer element 315.

  • the aerosol generating portion 322 is located at a downstream end (top of Figure 3A ) of the liquid transfer element 315, whilst the conveying portion 317 forms the remainder of the liquid transfer element 315.
  • the conveying portion 317 is elongate and substantially cylindrical.
  • the aerosol generating portion 322 is bulb/bullet-shaped, and comprises a portion which is wider (has a greater radius) than the conveying portion 317.
  • the aerosol generating portion 322 tapers to a tip at a downstream end of the liquid transfer element 315.

  • the liquid transfer element 315 and the conduit 324 are located in a substantially central position within the storage chamber 316 and are substantially parallel to a central longitudinal axis of the consumable component 303.
  • the porous nature of the liquid transfer element 315 means that the first (flavoured) aerosol precursor in the storage chamber 316 is drawn into the liquid transfer element 315. As the flavoured aerosol precursor in the liquid transfer element 315 is depleted in use, further flavoured aerosol precursor is drawn from the storage chamber 316 into the liquid transfer element 315 via a wicking action.
  • the storage chamber 316 is fluidly isolated from the liquid transfer element 315.
  • the isolation is achieved via a plug 320 (preferably formed from silicone) located at one end of a conduit 324 surrounding the liquid transfer element 315.
  • the plug may be replaced by any one of: a duck bill valve; a split valve or diaphragm; or a sheet of foil.
  • the storage chamber 316 further includes an air bleed channel 332, which in the deactivated state is sealed by a sealing element in the form of a pierceable membrane (preferably made from foil).
  • Activation (or piercing) member 330 which projects inwardly from the mouthpiece 309, and may take the form of a blade, pierces the pierceable membrane and opens the air bleed channel 332 when the consumable component 303 is moved to the activated state (as is discussed in more detail below).
  • the aerosol generating portion 322 is located within the first flow path 401.
  • the aerosol generating portion 322 constricts or narrows the first flow path 401.
  • This constricted or narrowed portion of the first flow path 401 defines an aerosolisation chamber 319 of the consumable component 303.
  • the aerosolisation chamber 319 which is adjacent the aerosol generating portion 322, is the narrowest portion of the first flow path 401.
  • the constriction of the first flow path 401 at the aerosolisation chamber 319 results in increased air velocity and a corresponding reduction in air pressure of the air flowing therethrough and thus may be referred to as a Venturi aperture.
  • the aerosolisation chamber 319 is generally toroidal in shape (extending circumferentially about the aerosol generating portion 322), but this toroidal shape may include one or more interruptions where supports extend inwardly to contact the aerosol generating portion 322 and to support the aerosol generating portion 322 within the aerosolisation chamber 319.
  • the cartomizer portion 301 of the consumable component 303 includes a reservoir 305 (defined by a container) for storing a second (e-liquid) aerosol precursor (which may contain nicotine).
  • a wick 311 extends into the reservoir so as to be in contact with (i.e. partially submerged in) the e-liquid aerosol precursor.
  • the wick 311 is formed from a porous wicking material (e.g. a polymer) that draws the e-liquid aerosol precursor from the reservoir 305 into a central region of the wick 311 that is located in the vaporising chamber 325.
  • a heater 314 is configured to heat the central region of the wick 311.
  • the heater 314 includes a resistive heating filament that is coiled around the central region of the wick 311.
  • the wick 311 and the heater 314 generally define a vaporiser, and together with the reservoir 305 act as an active aerosol generator.
  • the vaporiser (i.e. wick 311 and heater 314) and aerosol generating portion 322 are both at least partially located within the airflow passage, with the aerosol generating portion 322 being downstream of the vaporiser.
  • the consumable component 303 may be supplied with electrical power for activation of the heater 314, the consumable component 303 includes a pair of consumable electrical contacts 313.
  • the consumable electrical contacts 313 are configured for electrical connection to a corresponding pair of electrical supply contacts in the device (not shown).
  • the consumable electrical contacts 313 are electrically connected to the electrical supply contacts (not shown) when the consumable component 303 is engaged with the device.
  • the device includes an electrical power source, for example a battery.
  • Figure 3B shows the consumable component 303 of Figure 3A in an activated state.
  • mouthpiece portion 309 is moved along the central longitudinal axis 350 in an upstream direction towards cartomizer portion 301.
  • the mouthpiece portion 309 is fixed by a collar 308 to the conveying portion 317 of the liquid transfer element 315 and therefore liquid transfer element 315 moves with the mouthpiece portion 309.
  • the mouthpiece portion 309 and liquid transfer element 315 are moved relative to the tank 316.
  • activation/piercing member 330 contacts and pierces a sealing element in the form of a pierceable membrane extending across the air bleed channel 332 thereby fluidly connecting the vapour flow passage 321 the storage chamber 316. This allows air from the vapour flow passage 321 to enter the storage chamber 316 as aerosol precursor is removed from the storage chamber 316 by the liquid transfer element 315.
  • liquid transfer element 315 pushes on, and moves, plug 320 out of the conduit 324 which then allows liquid transfer element 315 to come into contact with the flavoured aerosol precursor stored in the storage chamber 316.
  • the plug 320 may then be unconstrained within the storage chamber, or may be pushed by liquid transfer element 315 into a holding location.
  • a user draws (or “sucks”, “pulls”, or “puffs") on the mouthpiece portion 309 of the consumable component 303, which causes a drop in air pressure at the aperture 307 thereby generating airflow through the inlet opening 306, along the first flow path 401 and into the user's mouth.
  • the heater 314 When the heater 314 is activated by passing an electric current through the heating filament in response to the user drawing on the mouthpiece portion 309 (the drawing of air may be detected by a pressure transducer), the e-liquid located in the wick 311 adjacent to the heating filament is heated and vaporised to form a vapour in the vaporising chamber 325.
  • the vapour condenses to form the e-liquid aerosol within the vapour outlet channel 323.
  • the e-liquid aerosol is entrained in an airflow along the vapour flow passage 321 and along the first flow path to the aperture 307 for inhalation by the user when the user draws on the mouthpiece portion 309.
  • the device supplies electrical current to the consumable electrical contacts 313. This causes an electric current flow through the heating filament of the heater 314 and the heating filament heats up. As described, the heating of the heating filament causes vaporisation of the e-liquid in the wick 311 to form the e-liquid aerosol.
  • the flavoured aerosol is sized to inhibit pulmonary penetration.
  • the flavoured aerosol is formed of particles with a mass median aerodynamic diameter that is greater than 70 microns.
  • the flavoured aerosol is sized for transmission within at least one of a mammalian oral cavity and a mammalian nasal cavity.
  • the flavoured aerosol is formed by particles having a maximum mass median aerodynamic diameter that is less than 100 microns. Such a range of mass median aerodynamic diameter will produce aerosols which are sufficiently small to be entrained in an airflow caused by a user drawing air through the device and to enter and extend through the oral and or nasal cavity to activate the taste and/or olfactory receptors.
  • the e-liquid aerosol generated is sized for pulmonary penetration (i.e. to deliver an active ingredient such as nicotine to the user's lungs).
  • the e-liquid aerosol is formed of particles having a mass median aerodynamic diameter of less than 1 micron. Such sized aerosols tend to penetrate into a human user's pulmonary system, with smaller aerosols generally penetrating the lungs more easily.
  • the e-liquid aerosol may also be referred to as a vapour.
  • the size of aerosol formed without heating (in the passive aerosolisation portion) is typically smaller than that formed by condensation of a vapour (formed within the active aerosolisation portion).
  • Figures 4-6 show a first example of a component 303' in accordance with the present invention. Except where otherwise described, the component 303' is that same as that discussed in relation to Figures 3A and 3B .

  • the mouthpiece nozzle 403 further includes a nozzle conduit 415 which extends upstream from the first outlet aperture 404 and into the mouthpiece portion 309'.
  • the conduit nozzle 415 defines the downstream portion of the first flow path 401 and also defines the aerosolisation chamber 319.
  • the nozzle conduit 415 is rotatably secured within the mouthpiece portion 309'.
  • the consumable component 303' (i.e. the mouthpiece portion 309') further includes two second channels 416a, 416b which define the downstream portions of two second flow paths 402 (which can be seen in Figure 6A ) and extend to second channel openings 400a, 400b in the downstream axial end face of the mouthpiece portion 309'.
  • the second flow paths 402 comprise (in a downstream flow direction) a vaporising chamber 325 of the cartomizer portion 301, a vapour outlet channel 323 (also within the cartomizer portion 301) and a flow passage of the flavour pod portion 302 and downstream portions within the second channels 416a, 416b.
  • the second flow paths 402 bypass the aerosol generating portion 332 of the flavour pod portion 302.
  • the second channel openings 400a, 400b are laterally off-set from and diametrically opposed either side of the nozzle conduit 415.
  • the mouthpiece nozzle 403 in the first position where the second outlet apertures 405a, 405b of the mouthpiece nozzle 403 are not in alignment with the second channel openings 400a, 400b of the mouthpiece portion 309. As such, the downstream end face of the mouthpiece nozzle 403 blocks the second channel openings 400a, 400b, and therefore blocks the second flow path 402.
  • the second (e-liquid) aerosol is forced to flow along the first flow path 401, picking up first (flavoured) aerosol as it passes through the aerosolisation chamber 319.
  • the user can inhale both e-liquid and flavoured aerosol through the first outlet aperture 404 of the mouthpiece nozzle 403.
  • Figures 6A and 6B show the first example with the mouthpiece nozzle in the second position.
