Definitions

  • Figure 8 shows an exploded diagram of an example consumable.
  • cellulosic gelling agents include, but are not limited to, hydroxymethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, carboxymethylcellulose (CMC), hydroxypropyl methylcellulose (HPMC), methyl cellulose, ethyl cellulose, cellulose acetate (CA), cellulose acetate butyrate (CAB), and cellulose acetate propionate (CAP).
  • the gelling agent comprises (or is) alginate and/or pectin, and may be combined with a setting or crosslinking agent (such as a calcium source) during formation of the aerosol-generating material.
  • a setting or crosslinking agent such as a calcium source
  • the aerosolgenerating material may comprise a calcium-crosslinked alginate and/or a calcium- crosslinked pectin.
  • the tobacco extract may contain nicotine at a concentration such that the aerosol-generating material comprises about 1 wt% 1.5 wt%, 2 wt% or 2.5wt% to about 6 wt%, 5 wt%, 4.5 wt% or 4 wt% (calculated on a dry weight basis) of nicotine. In some cases, there may be no nicotine in the aerosol-generating material other than that which results from any tobacco extract.
  • the aerosol-generating material may comprise less than about 65 wt% of a filler, such as from about 1 wt% to 60 wt%, or 5 wt% to 50 wt%, or 5 wt% to 30 wt%, or 10 wt% to 20 wt%.
  • the aerosol-generating material is too thick, then heating efficiency may be compromised. This adversely affects the power consumption in use. Conversely, if the aerosol-generating material is too thin, it may be difficult to manufacture and handle; a very thin material is harder to cast and may be fragile, compromising aerosol formation in use.
  • the non-combustible aerosol provision system or device may comprise a heater configured to heat but not burn the aerosol-generating substrate.
  • the heater may be, in some cases, a thin film, electrically resistive heater. In other cases, the heater may comprise an induction heater or the like. In yet further cases, the heater may be a combustible heat source or a chemical heat source which undergoes an exothermic reaction to produce heat in use.
  • the heater may heat but not burn the aerosolisable material(s) to between 120°C and 350°C in use. In some cases, the heater may heat but not burn the aerosolisable material(s) to between 140°C and 250°C in use. In some cases in use, substantially all of the aerosol-generating material is less than about 4 mm, 3 mm, 2 mm or 1 mm from the heater. In some cases, the solid is disposed between about 0.017 mm and 2.0 mm from the heater, suitably between about 0.1 mm and 1.0 mm. These minimum distances may, in some cases, reflect the thickness of a carrier that supports the aerosol-generating material. In some cases, a surface of the aerosol-generating material may directly abut the heater.
  • the non-combustible aerosol provision system may additionally comprise a cooling element and/or a filter.
  • the cooling element if present, may act or function to cool gaseous or aerosol components. In some cases, it may act to cool gaseous components such that they condense to form an aerosol. It may also act to space the very hot parts of the apparatus from the user.
  • the filter if present, may comprise any suitable filter known in the art such as a cellulose acetate plug.
  • the cooling segment 107 provides a physical displacement between the aerosol-generating composition 103 and the filter segment 109.
  • the physical displacement provided by the cooling segment 107 will provide a thermal gradient across the length of the cooling segment 107.
  • the cooling segment 107 is configured to provide a temperature differential of at least 40 degrees Celsius between a heated volatilised component entering a first end of the cooling segment 107 and a heated volatilised component exiting a second end of the cooling segment 107.
  • the cooling segment 107 is configured to provide a temperature differential of at least 60 degrees Celsius between a heated volatilised component entering a first end of the cooling segment 107 and a heated volatilised component exiting a second end of the cooling segment 107.
  • the presence of the filter segment 109 provides an insulating effect by providing further cooling to the heated volatilised components that exit the cooling segment 107. This further cooling effect reduces the contact temperature of the user’s lips on the surface of the filter segment 109.
  • the rows of ventilation holes 317 are located at least 11mm from the proximal end 313 of the article, suitably between 17mm and 20mm from the proximal end 313 of the article 301.
  • the location of the ventilation holes 317 is positioned such that user does not block the ventilation holes 317 when the article 301 is in use.
  • the slurry may comprise from about 50 wt%, 60 wt%, 70 wt%, 80 wt% or 90 wt% of solvent (WWB).
  • the aerosol-generating material or slurry of Embodiment 10 comprising about 20-40 wt% gelling agent.
