- a “non-combustible” aerosol provision system is one where a constituent aerosol-generating material of the aerosol provision system (or component thereof) is not combusted or burned in order to facilitate delivery of at least one substance to a user.
- the delivery system is a non-combustible aerosol provision system, such as a powered non-combustible aerosol provision system.
- the non-combustible aerosol provision system is an electronic cigarette, also known as a vaping device or electronic nicotine delivery system (END), although it is noted that the presence of nicotine in the aerosolgenerating material is not a requirement.
- the non-combustible aerosol provision system is an aerosolgenerating material heating system, also known as a heat-not-burn system. An example of such a system is a tobacco heating system.
- the non-combustible aerosol provision system is a hybrid system to generate aerosol using a combination of aerosol-generating materials, one or a plurality of which may be heated.
- Each of the aerosol-generating materials may be, for example, in the form of a solid, liquid or gel and may or may not contain nicotine.
- the hybrid system comprises a liquid or gel aerosol-generating material and a solid aerosol-generating material.
- the solid aerosol-generating material may comprise, for example, tobacco or a non-tobacco product.
- the non-combustible aerosol provision system may comprise a non- combustible aerosol provision device and a consumable for use with the non- combustible aerosol provision device.
- the disclosure relates to consumables comprising aerosolgenerating material and configured to be used with non-combustible aerosol provision devices. These consumables are sometimes referred to as articles throughout the disclosure.
- the non-combustible aerosol provision system such as a non-combustible aerosol provision device thereof, may comprise a power source and a controller.
- the power source may, for example, be an electric power source or an exothermic power source.
- the exothermic power source comprises a carbon substrate which may be energised so as to distribute power in the form of heat to an aerosol-generating material or to a heat transfer material in proximity to the exothermic power source.
- the non-combustible aerosol provision system may comprise an area for receiving the consumable, an aerosol generator, an aerosol generation area, a housing, a mouthpiece, a filter and/or an aerosol-modifying agent.
- the consumable for use with the non-combustible aerosol provision device may comprise aerosol-generating material, an aerosol-generating material storage area, an aerosol-generating material transfer component, an aerosol generator, an aerosol generation area, a housing, a wrapper, a filter, a mouthpiece, and/or an aerosol-modifying agent.
- a method of manufacture of a consumable for use with a non-combustible aerosol-provision device in which each consumable comprises a portion of a media to which is applied an aerosol generating material, in which the method comprises the following steps
- the media and aerosol generating material is separated into portions of a desired dimension.
- the characteristics, for example stiffness, of the media are such that portions of the media and aerosol generating material are suitable for use in an aerosol generating device without any further processing of the media and aerosol generating material. This has an advantage of minimising processing steps in the manufacture of the consumable.
- the characteristics of the media are such that portions of the media and aerosol generating material are not suitable for use in an aerosol generating device without further processing of the media and aerosol generating material.
- the media is a material that is one or both of thinner and less robust than is required for use as a consumable in an aerosol generating device.
- the media and aerosol generating material may be easier to handle, configure for storage, and I or occupy less space in storage than would be the case if the media had characteristics that rendered the media and aerosol generating material suitable for use as a consumable.
- the media and aerosol generating material are combined with a support.
- the method includes a further step of (f) at least one portion of the media and aerosol generating material is associated with a support.
- the support may be of a material suitable to form a substrate.
- the support may, for example, be or comprise paper, card, paperboard, cardboard, reconstituted material, a plastics material, a ceramic material, a composite material, glass, a metal, or a metal alloy.
- the support comprises a plastics material which can withstand the temperatures typically encountered in a non-combustible aerosol provision device.
- the support comprises polyether ether ketone (PEEK).
- PEEK polyether ether ketone
- the media provided in step (a) is a longitudinally extending material
- step (b) is performed before step (c)
- the storage configuration of step (c) is forming the media and aerosol generating material into a roll or a concertina.
- step (b) comprises applying the aerosol generating material to the media as two or more discrete portions of aerosol generating material.
- at least two of the discrete portions of aerosol generating material are formed from aerosol generating material with compositions different to each other. This has the advantage that a user of the consumable manufactured according to the present disclosure may have different experiences when different discrete portions of aerosol generating material on the consumable are aerosolised. This may make the use of the consumable more enjoyable and I or more interesting than use of a consumable that has aerosol generating material of only one composition.
- step (b) is performed two or more times. This may have the effect of producing thicker aerosol generating material on the media than a single application of aerosol generating material. An increased thickness may result in a greater amount of aerosol being generated by the aerosol generating material and I or provision of aerosol for a longer period of time than if only one application of aerosol generating material had occurred.
- the method further comprises a step of
- step (g) laying a protection sheet over the media and aerosol generating material, in which step (g) is performed after step (b) and before step (c).
- the protection sheet comprises one or more apertures which extend through the protection sheet.
- the number of apertures is the same as the number of discrete portions of aerosol generating material, and the configuration and location of the apertures coincides with at least part of each discrete portion of aerosol generating material once the protection sheet has been laid over the media and aerosol generating material.
- step (a) comprises selecting or creating a media that has first and second opposing surfaces, in which the first surface and the aerosol generating material adhere to each other with a first adhesive strength, the second surface and the aerosol generating material adhere to each other with a second adhesive strength, the first adhesive strength is greater than the second adhesive strength, and in step (b) the aerosol generating material is applied to the first surface of the media.
- the second adhesive strength is lower than the force required to pull the aerosol generating material into two portions.

- the folds at the lines of perforations 158 alternate between folding the first surfaces 136 of the panels 146 either side of the folding line of perforations 158 towards each other and folding those first surfaces away from each other.
- the media 130 is being folded, and in Figure 14, the media 130 is fully folded.
- a further embodiment of the method of production of a consumable according to the present disclosure includes providing a first media and portions of aerosol generating material 232, and a second media and portions of aerosol generating material 332.
- Each of those media and portions of aerosol generating material are produced as described in one of the embodiments described in connection with Figures 2 to 14.
- the difference between the portions of aerosol generating materials 232, 332 is that the composition of aerosol generating materials 232, 332 is different in that aerosol generated from aerosol generating material 232 has a first flavour, and aerosol generated from aerosol generating material 332 has a second flavour.
- first and second media are separated into foil portions 246, 346.
- the foil portions 246 of the first media are identified by a corner 248 being removed from each foil portion 246.
- the foil portions 346 of the second media are identified by a notch 348 being removed from an edge of each foil portion 346.
- a consumable 124 is produced by attaching one foil portion 246 from the first media and one foil portion 346 from the second media to a support 150. The attachment is made using an adhesive.
- the resultant consumable 124 includes six portions of aerosol generating material 232 which have a first flavour and six portions of aerosol generating material 332 which have a second flavour.
- the media 430 is a laminate which includes a first layer 460 and a second layer 462.
- the first layer 460 is a metal foil or metal film, in the illustrated example of Figure 17 an aluminium foil or film.
- the layer 460 can be thinner than the foil 34 or 134 discussed in the above discussed embodiments because layer 460 is not required to have the structural characteristics, in particular strength and resilience to damage, that foils 34 and 134 are required to have.
- the second layer 462 is a structural layer and is required to provide the media 430 with the strength and resilience to damage that it needs to allow it to be handled and stored in a storage configuration.
- the second layer 462 may be of a material suitable to form a substrate.
- the second layer 462 may, for example, be or comprise paper, card, paperboard, cardboard, reconstituted material, a plastics material, a ceramic material, a composite material, or glass.
- the media 430 may be used in the same fashion as media 30 or 130 described above.
- the portions of aerosol generating material 32, 232, 332 are in an embodiment of the present disclosure applied to the media 30, 130 in the form of a slurry. Once applied to the media the slurry needs to be dried or allowed to dry before the media can be configured into a storage configuration. Although the media could simply be allowed to dry over the course of time, such an approach renders the production of the media and portions of aerosol generating material 32, 232, 332 inefficient.
- a drying system comprises a bed 70 which is adapted to support a media and portions of aerosol generating material 32, 232, 234 (which is collectively designated as media and material 72) as it travels across the surface of the bed 70 in a direction 74.
- the portions of aerosol generating material 32, 232, 332 are located on the face of the media not in contact with the bed 70.
- a heat source 76 Spaced above the bed 70 is a heat source 76.
- the heat source 76 is spaced from the bed 70 by a distance sufficient to allow the media and material 72 to pass between the bed 70 and heat source 76 without contact between the media and material 72 and the heat source.
- a temperature sensor 78 measures the temperature of the media and material as it passes out from between the bed 70 and heat source 76. The temperature sensor 78 controls the heat source 76 to prevent the media and material 72 from exceeding a predetermined temperature.
- the heat source 76 is a dielectric heat source.
- dielectric heat source is a source of microwave radiation with a frequency of around 915 MHz or 2.45 GHz.
- the heat source is a radio frequency heating source.
- the electromagnetic waves for the dielectric heat source 76 cause heating of the slurry and promote evaporation of the solvent from the slurry as the media and material 72 passes between the heat source 76 and the bed 70.
- the heat source 76 is a source of thermal radiation.
- source is an infrared heater.
- the thermal radiation from the heat source 76 causes heating of the slurry and promotes evaporation of the solvent from the slurry as the media and material 72 passes between the heat source 76 and the bed 70.
- a second drying system comprises a bed 170 which is adapted to support a media and portions of aerosol generating material 32, 232, 234 (which is collectively designated as media and material 72) as it travels across the surface of the bed 170 in a direction 74.
- the portions of aerosol generating material 32, 232, 332 are located on the face of the media not in contact with the bed 170.
- the bed 70 comprises a heated material in the form of a resistively heated hot plate 176.
- the media and material 72 passes over the hot plate 176 and is heated thereby. This heating causes heating of the slurry and promotes evaporation of the solvent from the slurry.
- a temperature sensor 78 measures the temperature of the media and material 72 as it passes off the hot plate 176. The temperature sensor 78 controls the hot plate 176 to prevent the media and material 72 from exceeding a predetermined temperature.
- a third drying system comprises a bed 270 which is adapted to support a media and portions of aerosol generating material 32, 232, 234 (which is collectively designated as media and material 72) as it travels across the surface of the bed 270 in a direction 74.
- the portions of aerosol generating material 32, 232, 332 are located on the face of the media not in contact with the bed 270.
- the bed 270 comprises a susceptor 280. Close to the bed 270 is a magnetic field generator 276 which generates an alternating magnetic field. The alternating magnetic field causes the susceptor 280 to have an increased temperature relative to the surrounding temperature. The media and material 72 passes over the susceptor 280 and is heated thereby. This heating causes heating of the slurry and promotes evaporation of the solvent from the slurry.
- a temperature sensor 78 measures the temperature of the media and material 72 as it passes off the susceptor 280. The temperature sensor 78 controls the magnetic field generator 276 to prevent the media and material 72 from exceeding a predetermined temperature.
