Definitions

  • a device comprising a power supply and an electrical heater connected to the power supply;
  • an aerosol-forming substrate is a material or mixture of materials capable of releasing volatile compounds that can form an aerosol.
  • the provision of the aerosol-forming substrate in the form of a gel may be advantageous for storage and transport, or during use.
  • the risk of leakage from the device may be reduced.
  • Replenishing of the device with aerosol forming substrate when depleted or exhausted may also be improved, for example by reducing the risk of leakage or spillage.
  • the cartridge can be easily disposed of and replaced when the gel has been consumed.
  • Suitable aerosol-formers are well known in the art and include, but are not limited to: polyhydric alcohols, such as triethylene glycol, 1 ,3-butanediol and glycerine; esters of polyhydric alcohols, such as glycerol mono-, di- or triacetate; and aliphatic esters of mono-, di- or polycarboxylic acids, such as dimethyl dodecanedioate and dimethyl tetradecanedioate.
  • Preferred aerosol formers are polyhydric alcohols or mixtures thereof, such as triethylene glycol, 1 ,3-butanediol and, most preferred, glycerine or polyethylene glycol..
  • Flavour compounds may be contained in the second chamber in a gel.
  • flavour compound may be provided in another form.
  • the second chamber may contain a solid tobacco material that releases flavour compounds when heated.
  • the second chamber may contain, for example, one or more of: powder, granules, pellets, shreds, spaghettis, strips or sheets containing one or more of: herb leaf, tobacco leaf, fragments of tobacco ribs, reconstituted tobacco, homogenised tobacco, extruded tobacco and expanded tobacco.
  • the solid tobacco material in the second chamber may be in loose form.
  • the tobacco may be contained in a gel or liquid.
  • the second chamber may contain additional tobacco or non-tobacco volatile flavour compounds, to be released upon heating.
  • the device may comprise a device housing having a cavity for receiving the cartridge.
  • the cavity of the device may be substantially cylindrical.
  • the cavity has a diameter substantially equal to or slightly greater than the diameter of the cartridge.
  • the device may comprise a device body holding the power supply and the heater.
  • the aerosol-generating device may further comprise a mouthpiece separate to the device body.
  • the mouthpiece may be configured for engagement with the device body.
  • the device body may be configured to receive the cartridge in a cavity of the device body.
  • the cartridge may have any suitable shape.
  • the cartridge may have a length of, for example, between about 5 mm and about 30 mm. In certain embodiments the cartridge may have a length of about 12 mm.
  • the housing of the cartridge may be formed from one or more thermally conductive materials.
  • the interior of the cartridge may be coated or treated to comprise one or more thermally conductive materials.
  • Use of one or more thermally conductive materials to form the cartridge or coat the interior of the cartridge can advantageously increase heat transfer from the heater to the gel.
  • Suitable thermally conductive materials include, but are not limited to, metals such as, for example, aluminium, chromium, copper, gold, iron, nickel and silver, alloys, such as brass and steel and ceramics, or combinations thereof.
  • at least one wall of the housing has a thermal conductivity greater than 10 Watts per metre per Kelvin at room temperature.
  • the housing comprises a least one wall formed from aluminium.
  • Cartridges for use in aerosol-generating systems according to the present invention may be formed by any suitable method. Suitable methods include, but are not limited to, deep drawing, injection moulding, blistering, blow forming and extrusion.
  • the substrate container may be sealed by one or more removable barriers.
  • the substrate container may be sealed by one or more peel-off seals.
  • the one or more removable barriers may be formed from any suitable material.
  • the one or more removable barriers may be formed from a foil or film, for example comprising a metal.
  • the electrical heater may surround the substrate cartridge.
  • the electrical heater may comprise one or more electrically resistive tracks on a flexible substrate.
  • the electrical heater comprises one or more electrically resistive tracks on a rigid substrate material.
  • the electrical heater projects into the cavity of the device.
  • Figure 4 is a schematic illustration of an aerosol-generating system in accordance with a further embodiment of the invention.
  • the cartridge housing is formed of aluminium, which is a good thermal conductor.
  • the heater is never in contact with the gel or any generated vapour or aerosol. It is held in the blind slot 34 and so is isolated from the generated aerosol. This ensures that there is no build-up of condensates on the heater, which might lead to the generation of undesirable compounds in operation.
  • Figure 3b shows the cartridge inserted into the device, with the heater 22 received in the slot 34 between the chambers.
  • a mouthpiece portion 14 is then connected to the device body portion 12.
  • Figure 3b illustrates the direction of insertion of the mouthpiece portion.
  • the mouthpiece portion is provided with piercing elements 52 which act to pierce the frangible sealing element and provide an escape passage 54 for vapour generated in the first and second chambers.
  • a sealing element is provided to seal the first and second chambers in the same manner as described with reference to Figure 1 .
  • a cartridge piercing arrangement similar to that shown in Figure 3 may be used to open the cartridge using the mouthpiece portion 1 14, with suitable adaptations made for the different airflow path.
  • a simple peelable seal may be used and a vapour permeable membrane provided across the open end of the first and second chambers 230, 232.
  • the system is configured to operate in a continuous heating mode as in the embodiment of Figure 1 .
  • the device supplies an AC signal to the induction coil in order to generate an alternating magnetic field in the cavity. This induces current flow in the susceptor resulting in a heating of the susceptor. If a ferromagnetic material is used as the susceptor, hysteresis losses may also contribute to the heating.
  • the induction coil may be described as an induction heater in this context.
  • a temperature sensor may be provided within the cavity and a feedback control loop used.
  • the mouthpiece tube is formed from cardboard and has a diameter of 6.6mm and a length of 45 mm.
  • Lining tubes 340 are formed from polyetheretherketone (PEEK) and are provided to prevent the cardboard mouthpiece tube from absorbing moisture from within the mouthpiece tube.
  • the lining tubes can be made very thin, in this embodiment having a thickness of 0.3mm.
  • a restrictor 350 is provided to restrict the airflow to ensure mixing of air with vapour from the cartridge and ensure the generation of an aerosol within the space following the restrictor, in lining tube 360.
  • the cartridge shown in Figures 5a and 5b may be heated by heater of the type shown in Figure 1 or of the type shown in Figures 4 or 7a (described below).
  • the system is configured to operate in a continuous heating mode as in Figure 1 . This means that the heater heats the cartridge throughout an operating session rather than in response to sensed user puffs.
  • the user turns the system on using a simple switch (not shown) and the heater heats the cartridge.
  • the gels in the first and second chambers become liquid upon heating and vapour containing nicotine and glycerin is generated at temperatures between 180°C to 250°C.
  • the aerosol-generating device 400 further comprises a mouthpiece 412 attachable to a proximal end of the aerosol-generating device housing 402 by a push fitting or screw fitting.
  • the mouthpiece comprises a piercing portion 414, air inlets 418 and an air outlet 416.
  • Figure 7b shows a cross-sectional view of the aerosol-generating device 400 with a container 500 received in the cavity 408 of the housing.
  • a user inserts the container 500 into the cavity 108 of the aerosol-generating device 400, and then attaches the mouthpiece 412 to the housing 402.
  • the piercing portion 414 pierces the sealing foil 514 of the container, and forms an airflow pathway 415 from the air inlets 418, through the container to the air outlet.
  • the user presses a button (not shown) to activate the device.
  • the heater is supplied with power by the control electronics 406 from the power supply 404. The heater then directly heats the external wall of the cartridge.
  • the embodiments described have each been described as configured to operate a continuous heating scheme, in which the heater is activated for a predetermined time period during which a user may take several puffs.
  • the systems described may be configured to operate in different ways. For example, power may be provided to the heater or induction coil for only the duration of each user puff, based on signals from an airflow sensor within the system. Alternatively, or in addition, power to the heater or induction coil may be switched on and off in response to user actuation of a button or switch.
