Definitions

  • colourants may be used depending on the desired colour of the amorphous solid.
  • the colour of amorphous solid may be, for example, white, green, red, purple, blue, brown or black. Other colours are also envisaged.
  • Natural or synthetic colourants such as natural or synthetic dyes, food-grade colourants and pharmaceutical-grade colourants may be used.
  • the colourant is caramel, which may confer the amorphous solid with a brown appearance.
  • the colour of the amorphous solid may be similar to the colour of other components (such as tobacco material) in an aerosol-generating composition comprising the amorphous solid.
  • the addition of a colourant to the amorphous solid renders it visually indistinguishable from other components in the aerosol-generating composition.
  • the aerosol-generating article may additionally comprise ventilation apertures. These may be provided in the sidewall of the article. In some cases, the ventilation apertures may be provided in the filter and/or cooling element. These apertures may allow cool air to be drawn into the article during use, which can mix with the heated volatilised components thereby cooling the aerosol.
  • the ventilation enhances the generation of visible heated volatilised components from the article when it is heated in use. The heated volatilised components are made visible by the process of cooling the heated volatilised components such that supersaturation of the heated volatilised components occurs.
  • FIG. 1 and 2 there are shown a partially cut-away section view and a perspective view of an example of an aerosol-generating article 101.
  • the article 101 is adapted for use with a device having a power source and a heater.
  • the article 101 of this embodiment is particularly suitable for use with the device 51 shown in Figures 5 to 7, described below.
  • the article 101 may be removably inserted into the device shown in Figure 5 at an insertion point 20 of the device 51.
  • the ventilation holes can be made using any suitable technique, for example, one or more of the following techniques: laser technology, mechanical perforation of the cooling segment 307 or pre-perforation of the cooling segment 307 before it is formed into the article 301.
  • the ventilation holes 317 are positioned so as to provide effective cooling to the article 301.
  • the heater arrangement 23 is supported by a stainless steel support tube and comprises a polyimide heating element.
  • the heater arrangement 23 is dimensioned so that substantially the whole of the body of aerosol generating material 103, 303 of the article 101, 301 is inserted into the heater arrangement 23 when the article 101, 301 is inserted into the device 51.
  • the article 101, 301 is removably inserted into an insertion point 20 of the device 51, as shown in Figures 5 to 7.
  • the body of aerosol generating material 103, 303 which is located towards the distal end 115, 315 of the article 101, 301, is entirely received within the heater arrangement 23 of the device 51.
  • the proximal end 113, 313 of the article 101, 301 extends from the device 51 and acts as a mouthpiece assembly for a user.
  • the heater arrangement 23 will heat the article 101, 301 to volatilise at least one component of the aerosol generating material from the body of aerosol generating material 103, 303.
  • the primary flow path for the heated volatilised components from the body of aerosol generating material 103, 303 is axially through the article 101, 301, through the chamber inside the cooling segment 107, 307, through the filter segment 109, 309, through the mouth end segment 111, 313 to the user.
  • the temperature of the heated volatilised components that are generated from the body of aerosol generating material is between 60°C and 250°C, which may be above the acceptable inhalation temperature for a user.
  • the slurry is applied to a support.
  • the layer may be formed on a support.
  • the slurry comprises gelling agent, aerosol-former material and active substance.
  • the slurry may comprise these components in any of the proportions given herein in relation to the composition of the amorphous solid.
  • the slurry may comprise (on a dry weight basis): gelling agent and, optionally, filler, wherein the amount of gelling agent and filler taken together is about 10 to 60wt% of the slurry; aerosol-former material in an amount of about 40 to 80wt% of the slurry; and - optionally, active substance in an amount of up to about 20wt% of the slurry.
  • the setting the gel (c) may comprise supplying a setting agent to the slurry.
  • the slurry may comprise sodium, potassium or ammonium alginate as a gel- precursor, and a setting agent comprising a calcium source (such as calcium chloride), may be added to the slurry to form a calcium alginate gel.
  • the setting agent comprises or consists of calcium acetate, calcium formate, calcium carbonate, calcium hydrogencarbonate, calcium chloride, calcium lactate, or a combination thereof.
  • the setting agent comprises or consists of calcium formate and/or calcium lactate.
  • the setting agent comprises or consists of calcium formate.
  • the inventors have identified that, typically, employing calcium formate as a setting agent results in an amorphous solid having a greater tensile strength and greater resistance to elongation.
  • the total amount of the setting agent, such as a calcium source may be 0.5-5wt% (calculated on a dry weight basis).
  • the discussion herein relating to the solid composition is explicitly disclosed in combination with the slurry aspect of the invention.
  • the method comprises heating the aerosol-generating composition to a temperature of less than or equal to 350 °C.
  • the method typically comprises heating the aerosol-generating composition to a temperature of from about 220 °C to about 280 °C.
  • the method comprises heating at least a portion of the aerosol-generating composition to a temperature of from about 220 °C to about 280 °C over a session of use.
