Definitions

  • Certain tobacco industry products produce an aerosol during use, which is inhaled by a user.
  • tobacco heating devices heat an aerosol generating substrate such as tobacco to form an aerosol by heating, but not burning, the substrate.
  • Such tobacco industry products commonly include mouthpieces through which the aerosol passes to reach the user’s mouth.
  • the mouthpiece 2 in the present example, includes a hollow tubular element 4, and a body of material 6 upstream of the hollow tubular element 4, in this example adjacent to and in an abutting relationship with the hollow tubular element 4.
  • the breakable capsule 11 has a core-shell structure. That is, the encapsulating material or barrier material creates a shell around a core that comprises the aerosol modifying agent.
  • the shell structure hinders migration of the aerosol modifying agent during storage of the article 1 but allows controlled release of the aerosol modifying agent, also referred to as an aerosol modifier, during use.
  • Salts of alginic acid include ammonium alginate, triethanolamine alginate, and group I or II metal ion alginates like sodium, potassium, calcium and magnesium alginate.
  • Esterified alginates include propylene glycol alginate and glyceryl alginate.
  • the barrier material is sodium alginate and/ or calcium alginate.
  • Suitable cellulosic materials include methyl cellulose, ethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, carboxymethyl cellulose, cellulose acetate and cellulose ethers.
  • the gelling agent may comprise one or more modified starches.
  • the gelling agent may comprise carrageenans.
  • the filamentary tow forming the hollow tubular element 4 preferably has a total denier of less than 45,000, more preferably less than 42,000. This total denier has been found to allow the formation of a tubular element 4 which is not too dense.
  • the total denier is at least 20,000, more preferably at least 25,000.
  • the filamentary tow forming the hollow tubular element 4 has a total denier between 25,000 and 45,000, more preferably between 35,000 and 45,000.
  • the cross-sectional shape of the filaments of tow are ⁇ ’ shaped, although in other embodiments other shapes such as‘X’ shaped filaments can be used.
  • the total denier of the tow forming the body of material 6 is preferably at most 30,000, more preferably at most 28,000 and still more preferably at most 25,000. These values of total denier provide a tow which takes up a reduced proportion of the cross sectional area of the mouthpiece 2 which results in a lower pressure drop across the mouthpiece 2 than tows having higher total denier values.
  • the tow preferably has a total denier of at least 8,000 and more preferably at least 10,000.
  • the denier per filament is between 5 and 12 while the total denier is between 10,000 and 25,000. More preferably, the denier per filament is between 6 and 10 while the total denier is between 11,000 and 22,000.
  • the cross-sectional shape of the filaments of tow are ⁇ shaped, although in other embodiments other shapes such as‘X’ shaped filaments can be used, with the same d.p.f. and total denier values as provided herein.
  • the use of a coil enables the non-combustible aerosol provision device to reach operational temperature more quickly than a non-coil aerosol provision device.
  • the non-combustible aerosol provision device including a coil as described above can reach an operational temperature such that a first puff can be provided in less than 30 seconds from initiation of a device heating program, more preferably in less than 25 seconds.
  • the device can reach an operational temperature in about 20 seconds from the initiation of a device heating program.
  • At least 10 pg of nicotine is aerosolised from the aerosol generating material; the weight ratio in the generated aerosol, of aerosol forming material to nicotine is at least about 2.5:1, suitably at least 8.5:1;
  • the non-combustible aerosol provision device is arranged to heat the aerosol forming material 3 of the article 1, to a maximum temperature of at least about 200°C, or at least about 220°C, or at least about 240°C, more preferably at least about 270°C, at least once during the heating process followed by the non-combustible aerosol provision device.
