DETAILED DESCRIPTION


FIG. 1 illustrates a schematic view of an aerosol provision (AP) system 100. The AP system 100 is for generating an aerosol for inhalation by a user. The AP system 100 as illustrated in this example may be designed to simulate a cigarette and therefore as a non-limiting example may have a substantially cylindrical shape and be approximately the same size as a cigarette. In other embodiments, AP system 1 may have a different shape, such as a substantially planar shape, a substantially cuboid shape, a substantially spherical shape, a trapezoidal shape, or other shape.


The AP system 100 has a consumable 110 and an aerosol generator 120. The consumable 110 has a plurality of aerosol generating material portions. The aerosol generator 120 is operable to generate an aerosolised payload by providing a predetermined heating profile to at least one of the plurality of aerosol generating material portions. In an example, the predetermined heating profile may be pre-programmed in a controller of the AP system 100. In an example, the predetermined heating profile is selected based on a coded portion of the consumable 110. In an example, the AP system may be provided with a controller wherein the controller already comprises a predetermined heating profile pre-programmed within it. Alternatively, in an example a user may select the predetermined heating profile prior to use, such that the predetermined heating profile may be pre-programmed in a controller of the AP system 100 prior to use. A user selecting the predetermined heating profile prior to use may comprise the user selecting one or more heating profile parameters, such that the predetermined heating profile is created according to the selected one or more heating profile parameters. The user may select or create a different predetermined heating profile prior to each use. In an example, the controller of the AP system 100 comprises a memory and a processor, wherein the heating profile pre-programmed in the controller comprises the heating profile being stored on the memory. In an example, the memory comprises a local memory, or a remote memory wherein the controller is comprises communication means to access the remote memory.


The consumable 110 may be loaded into the AP system 100 prior to use. Alternatively, the consumable 110 may be provided as an integral part of the AP system 100 and the AP system 100 may be discarded after the consumable 110 is depleted.



FIG. 2 illustrates a schematic view of an AP system 100. The AP system 100 has a consumable 100 and an aerosol generator 120. The AP system 100 also has an outlet 102 through which an aerosol may pass.


The aerosol generator 120 as shown in the example of FIG. 2 includes a controller 122 in which a predetermined heating profile may be pre-programmed. This heating profile may be used in heating the consumable 110 when the AP system 100 is initially activated or in response to a particular type of consumable 110. The controller 122 is connected to a heater 124. The heater 124 may be an electrical resistive heater, an inductive heater, a chemical heater or any related elements of those heater systems. The heater 124 provides energy to the consumable 110 to generate an aerosol from the consumable. The heater 124 may heat any or select portions contained within the aerosol generating material portions. The controller 122 may send signals to the heater 124 to control the heating profile provided to the consumable 110 by the heater 124.


The heater 124 may comprise one or more electrically resistive heaters, including for example one or more nichrome resistive heater(s) and/or one or more ceramic heater(s). The one or more heaters may comprise one or more induction heaters which includes one or more susceptors which may form a chamber into which a consumable 110 comprising aerosol generating material portions is inserted or otherwise located in use. Alternatively, the one or more susceptors may be positioned near or adjacent a consumable 110 comprising aerosol generating material portions located in use Alternatively or in addition, one or more susceptors may be provided in one or more of the aerosol generating material portions. In one example, one or more susceptors may be provided elsewhere in the consumable, such as adjacent one or more of the aerosol generating material portions. Other heating arrangements may also be used.



FIG. 3 illustrates a schematic view of an AP system 100. The AP system 100 has a consumable 110 and an aerosol generator 120. The AP system 100 has an outlet 102.


The consumable 110, in the example shown in FIG. 3, comprises an aerosol generating material portion 112. The consumable 110 may have a plurality of aerosol generating material portions 112. The aerosol generating material portion or portions (where relevant) 112 may be any of tobacco, a nicotine containing material, menthol, an acid containing gel (for controlling protonation), glycerol etc. Other materials may be of different flavors. In an example, nicotine within the aerosol generating material 112 is heated to provide nicotine to the aerosol and glycerol within the aerosol generating material 112 is heated accordingly to provide a desired cloud volume. Varying the heating provided to acid within the aerosol generating material 112 alters the level of protonation of the nicotine (in the event that nicotine is also heated).


The nicotine material within the aerosol generating material 112 may contain any of a nicotine free base, nicotine benzoate, nicotine malate, nicotine pyruvate, and nicotine succinate.


The consumable 110 as shown in the example of FIG. 3 also has a coded portion 114. The coded portion 114 contains a code that may indicate to the aerosol generator 120 an appropriate heating profile for use with the consumable 110. The coded portion 114 may be a bar code, QR code, an identifiable color code, or the like. In an example, the consumable 110 comprises a one or more susceptors comprising the coded portion 114. The code may be encoded in a response of the one or more susceptors to one or more induction heaters. For example, the one or more induction heaters may comprise one or more magnetic field generators for generating a varying magnetic field, such that the response of the one or more susceptors is a response arising from an interaction between the one or more susceptors and the varying magnetic field. The coded portion 114 may be read by a sensor or reader or the like which sends a signal to the aerosol generator 120.


The AP system 100 of FIG. 3 has a sensor or reader 126 for detecting the coded portion 114 of the consumable 110 and sending a signal to the controller 122. The sensor 126 may be part of the aerosol generator 120. The sensor 126 of FIG. 3 is shown connected to the controller 122 of the aerosol generator 120. In an example, the sensor 126 detects the coded portion 114 of the consumable and sends a signal to the controller 122. The controller 122 then signals to the heater 124 to generate a heating profile suitable to the aerosol generating material portion 112. The heater 124 then heats the aerosol generating material portion or portions 112 in the consumable to produce an aerosol which flows through the outlet 102 and is suitable for inhalation by a user.


The sensor may be a bar code reader, a QR code reader, an IR detector, an RFID detector, an optical sensor or the like. The sensor in the AP system 100 may recognise when the consumable 110 is placed within and removed from the system 100. The AP system 100 may be prevented from operation when the system 100 has no consumable within the system 100 as a safety precaution. This will also prevent the system 100 from being used with non-authentic consumables 110 as the sensor will not signal to the controller to allow the AP system 100 to operate as the sensor will not recognise the consumable 110 without an authentic coded portion 114. This advantageous protects the system 100 from misuse with non-authentic consumables 110 which may extend the lifetime of the system 100.



FIG. 4 illustrates a schematic view of an AP system 100. The consumable 110 shown in the example of FIG. 4 has two portions of aerosol generating material 112A, 112B and the consumable 110 has two coded portions 114A, 114B. One coded portion 114A corresponds to one of the aerosol generating material portions 112A, and the other coded portion 114B corresponds to the other aerosol generating material portion 112B.


One of the portions of aerosol generating material may be a first aerosol generating material and the other portion may be a second aerosol generating material wherein the two aerosol generating materials are different. In an example, one aerosol generating material may be a nicotine containing compound such as tobacco and the other aerosol generating material may be menthol or the like.


In an example, there may be a number of coded portions 114A, 114B equivalent to the number of portions 112A, 112B of aerosol generating material in the consumable 110. Each coded portion 114A, 114B may be detected prior to heating of the aerosol generating material in the consumable 110. In another example, there may be fewer coded portions 114A, 114B than portions 112A, 112B of aerosol generating material in the consumable. Certain coded portions 114A, 114B may be the same, in that a subset of coded portions may the same where each refers to a portion of aerosol generating material that requires the same heating profile. A different subset of coded portions 114A, 114B may relate to portions of aerosol generating material that require a different heating profile to provide an aerosol.


Different coded portions 114A, 114B may signal to the heater 124 to provide different heating profiles to the aerosol generating material. Certain different coded portions 114A, 114B may however lead to the same heating profiles being provided, if for example a predetermined heating profile is suitable for heating both a flavorant portion and a menthol portion of aerosol generating material.


The sensor 126 may detect that the consumable 110 has two coded portions 114A, 114B and signal to the controller that a heating profile suitable for that particular consumable is to be used during the smoking session involving this consumable 110.


The AP system 100 of the present disclosure may have a power source and activation mechanism etc., however these are not displayed in the Figures. The power source may be any suitable power source but may include a battery or the like. Activation mechanism may be any suitable activation mechanism such as a button which is pressed by a user prior to, or during, use to initiate the aerosol generator 120 or a puff detector which detects when the user is inhaling and therefore initiates the aerosol generator 120.


The default predetermined heating profile delivered by the AP system 100 may be a standard heating profile in the sense that it delivers a manufacturer-defined “standard” user experience from an associated consumable 110. This “standard” user experience may be based on the median user experience desired from such an AP system 100. Use of a default predetermined heating profile removes the requirement on the user to specify their preferences on a device with which the user may not have a great level of familiarity. In this way, the default heating profile enables a user to “plug and play” and begin using the device comfortably as soon as they have the device.


As the user grows in familiarity with the device, the user may wish to personalise, i.e. amend, the default setting and there may be an input section on the device for enabling a user to personalise the heating profile based on the composition of the aerosol desired by the user. This may be via a user interface on the device such as a touch screen or the like on the AP system 100, or may be via a wired or wireless communication to the device. The AP system 100 may be operated via e.g. BlueTooth® or a LAN or via a smartphone or other such device.


The personalisation may be for the heating profile delivered to the aerosol generating material 112 during one puff or may be over a series of puffs. In an example, the user may opt for the heating profile for the first puff to remain as the default predetermined heating profile but opt to edit the heating profile for subsequent puffs. A smoking session typically includes 12 or more puffs and therefore the heating profile for each puff may be the same or different and each heating profile may be personalized by the user.


The default predetermined heating profile may vary depending on the code (in examples provided by the coded portion 114) detected on the consumable 110. In this way, the user is provided with a suggestion (curated by the manufacturer) for an initial heating profile based on the manufacturer's testing relating to the specific consumable 110 being used in the smoking session. This saves the user manually changing the heating profile each time the user changes the consumable 110 in the AP system 100. In an example, two users may use the same AP system 100. When the first user inserts their consumable 110 in the AP system 100, the aerosol generator 120 prepares and delivers a predetermined heating profile suitable to that consumable 110. The first user may then remove their consumable 110 and the second user may insert their consumable 110. The aerosol generator 120 recognises the change in consumable 110, prepares and delivers a different predetermined heating profile suitable to that new consumable 110. The users therefore are provided with suitable smoking experiences for their consumables. Furthermore, the AP system 100 therefore delivers a suitable heating power during each smoking session. The result is that the AP system 100 efficiently provides aerosol to a user over a large number of consumables 110.


This AP system 100 therefore reduces the likelihood of the delivery of an unsuitable heating profile being delivered to any particular consumable 110. This, in turn, reduces the likelihood of undesired events such as hot puff, dry out, burnt flavors or the lack of production of aerosol (due to a heating profile with not enough heating energy being provided). In this way, the AP system 100 protects important components such as the heater 124 from overheating and therefore increases the lifetime of the AP system 100.


Any factor of the heating profile may be controlled by the controller 122. This includes the heating power, temperature set point, heating time, heating curve, delays between heating and, in the event that multiple heaters are present in the AP system 100, the activation of particular heaters within the AP system 100.


In an example, the consumable contains aerosol generating material in a solid form. The consumable 110 may be in the form of cartridges which are removably insertable into the AP system 100. The AP system 100 described in this example therefore also facilitates changing consumable 110 due to the clean insertion and removing of consumables 110. There is no decantation required when the user wishes to change aerosol generating materials in 112 the AP system 100. Furthermore, the use of cartridges containing different coded portions 114 alongside the present AP system 100 enables multiple users to easily and quickly use the AP system 100 by swapping cartridges in the AP system 100 and having the AP system 100 apply a suitable heating profile to the aerosol generating material 112 of the new cartridge immediately. Use of cartridges in the present AP system 100 removes the need for a user to access the inner of the system 100. Instead, the user may simply insert and remove the cartridge to enable a change of/replenishment in the aerosol generating material 112.


The aerosol generating material 112 may be arranged exclusively on a carrier support. The carrier support may be a surface on one side of which the aerosol generating material 112 is arranged and on the other side of which the coded portion 114 is arranged. The carrier support may be a film or sheet or the like. In the example described above the carrier support has two sides, however there is no requirement for the carrier support to be restricted to such a shape, for example the carrier support may be substantially cylindrical shape, triangular shape, square tube shape or the like. The carrier support in any of these examples may be hollow or solid. In the example wherein the carrier support has a plurality of sides, the aerosol generating material 112 may be constrained to only one side or to all but one side of the carrier support. In an alternate example, the aerosol generating material 112 may be arranged on all sides of the carrier support. The carrier support may be heat conducting so as to carry heat from the heater 124 to the aerosol generating material 112 located on the carrier support. The carrier support may be formed from cardboard or paper or the like.


The AP system 100 may have a heater 124 which comprises a plurality of heating elements. In this example, each of the heating elements may correspond to a particular aerosol generating material within the aerosol generating material 112. For example, if the consumable 110 contains nicotine, glycerol and an acid, each of these may have a particular heating element to provide heat to that particular aerosol generating material 112. This enables further personalisation of the aerosol produced by the AP system 100.


The AP system 100 may have a power chamber (not shown) comprising a power source for supplying power to the heater 124. The heater 124 in the described example may be an electrically resistive heater. However, in other examples, the heater 124 may be a chemically activated heater which may or may not operate via exothermic reactions or the like. The heater 124 may be part of an inductive heating system, wherein the heater 124 is the source of energy for inductive heating, such as a coil of copper wire, and the carrier support may be or may contain a susceptor or the like. The susceptor may for example be a sheet of aluminium foil or the like. In an example, the heating elements are not all the same type of heating element. In an example, at least one heating element of the heater 124 is an electrically resistive heater, another heating element is a chemically activated heater and optionally another heating element is an inductive heater.


In an example, the plurality of aerosol generating materials (nicotine, glycerol, acid) in the aerosol generating material 110 and the plurality of heating elements in the heater 124 may be different in number. For example, one heating element may heat two aerosol generating materials if it is desired for these to always be heated together. Conversely, two heating elements may be used for respective aerosol generating materials in one instance, but may be used in concert to heat a larger quantity of aerosol generating material (for example for a major component of the aerosol, or one that is consumed more frequently) in another instance.


In use, the heating elements of the heater 124 may be activated at the same time or may be operated with a delay between operation. This may be used to enable particular notes of an aerosol to be more or less prevalent in the overall aerosol or smoking session. In an example, a particular heating element may heat a particular material, e.g. tobacco, at a first time to produce a tobacco aerosol for inhalation. This may be shortly followed by a different heating element heating a different material, e.g. menthol at a second time to follow the tobacco aerosol with a menthol aerosol with which the user desires to conclude the smoking session.


Complex combinations of profiles may be utilised to produce a highly specific combination of blends and release time so that the aerosol is highly personalizable.


In an example, a first heating element heats a first material within the aerosol generating material 112 for a first amount of time and a second heating element heats a second material within the aerosol generating material 112 for a second amount of time, wherein the first amount of time and the second amount of time are different. This enables greater personalisation of aerosol. This also enables production of aerosol with different notes during the smoking session. In an example, a nicotine aerosol generating material may be heated for e.g. 2 seconds to produce an aerosol and a flavor containing aerosol generating material may be heated for e.g. 5 to 7 seconds. These two times for these two different aerosol generating materials different due to the energy required to sufficiently heat the flavor containing aerosol generating material.


In an example, a first heating element heats a first material within the aerosol generating material 112 at a first power level and a second heating element heats a second material within the aerosol generating material 112 at a second power level, wherein the first power level and the second power level are different power levels. This further enables greater personalisation of a produced aerosol. As the aerosol released will be related to the power at which the heater 124 operates, flavors can be released at different times in the session which, as above, leads to a level of control over the production of different notes within the smoking session.


The power level may be related to the power at which the specific heating element is operated, the rate of heat delivery or the temperature that the heater 124 reaches during the heating phase.


In an example, the default heating profile may heat for 10 seconds to a temperature of 140 degrees and then ramp to a pre-set operating temperature, T1-T4, which could be 160, 170, 180, 190 or 200 degrees Celsius respectively. This operating temperature is then held for a fixed period of time, determine by that which is being heated, and then return to its initial hold temperature until the next puff.


In an example, the aerosol generating material 112 may be in the form of at least one of a gel and a solid. A gel or a solid, unlike a liquid, would not require a reservoir to be contained within and as such reduces the cost of the device overall, by removing the requirement for an additional component. In general, the lack of requirement of the reservoir reduces the complexity of the AP system 100 presented herein. Furthermore, the construction of the cartridge may be less complex when the material is in a gel or solid form.


In some embodiments, the aerosol generating material comprises one or more polyhydric alcohols, such as propylene glycol, triethylene glycol, 1,3-butanediol and glycerin; esters of polyhydric alcohols, such as glycerol mono-, di- or triacetate; and/or aliphatic esters of mono-, di- or polycarboxylic acids, such as dimethyl dodecanedioate and dimethyl tetradecanedioate.

Aerosolizable material, which also may be referred to herein as aerosol generating material, is material that is capable of generating aerosol, for example when heated, irradiated or energized in any other way. Aerosolizable material may, for example, be in the form of a solid, liquid or gel which may or may not contain nicotine and/or flavorants. In some embodiments, the aerosolizable material may comprise an “amorphous solid”, which may alternatively be referred to as a “monolithic solid” (i.e. non-fibrous). In some embodiments, the amorphous solid may be a dried gel. The amorphous solid is a solid material that may retain some fluid, such as liquid, within it. In some embodiments, the aerosolizable material may for example comprise from about 50 wt %, 60 wt % or 70 wt % of amorphous solid, to about 90 wt %, 95 wt % or 100 wt % of amorphous solid.


In examples, the amorphous solid may comprise a setting agent. The setting agent may comprise or consist of calcium acetate, calcium formate, calcium carbonate, calcium hydrogencarbonate, calcium chloride, calcium lactate, or a combination thereof. In some examples, the setting agent comprises or consists of calcium formate and/or calcium lactate. In particular examples, the setting agent comprises or consists of calcium formate. It has been 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 amorphous solid may comprise a colorant. The addition of a colorant may alter the visual appearance of the amorphous solid. The presence of colorant in the amorphous solid may enhance the visual appearance of the amorphous solid and the aerosol-generating material. By adding a colorant to the amorphous solid, the amorphous solid may be color-matched to other components of the aerosol-generating material or to other components of an article comprising the amorphous solid.


A variety of colorants may be used depending on the desired color of the amorphous solid. The color of amorphous solid may be, for example, white, green, red, purple, blue, brown or black. Other colors are also envisaged. Natural or synthetic ants, such as natural or synthetic dyes, food-grade colorants and pharmaceutical-grade colorants may be used. In certain embodiments, the ant is caramel, which may confer the amorphous solid with a brown appearance. In such embodiments, the color of the amorphous solid may be similar to the color of other components (such as tobacco material) in an aerosol-generating material comprising the amorphous solid. In some embodiments, the addition of a colorant to the amorphous solid renders it visually indistinguishable from other components in the aerosol-generating material.


The colorant may be incorporated during the formation of the amorphous solid (e.g. when forming a slurry comprising the materials that form the amorphous solid) or it may be applied to the amorphous solid after its formation (e.g. by spraying it onto the amorphous solid).


The aerosolizable material may comprise one or more active constituents, one or more carrier constituents and optionally one or more other functional constituents.


The active constituent may comprise one or more physiologically and/or olfactory active constituents which are included in the aerosolizable material in order to achieve a physiological and/or olfactory response in the user. The active constituent may for example be selected from nutraceuticals, nootropics, and psychoactives. The active constituent may be naturally occurring or synthetically obtained. The active constituent may comprise for example nicotine, caffeine, taurine, or any other suitable constituent. The active constituent may comprise a constituent, derivative or extract of tobacco or of another botanical. In some embodiments, the active constituent is a physiologically active constituent and may be selected from nicotine, nicotine salts (e.g. nicotine ditartrate/nicotine bitartrate), nicotine-free tobacco substitutes, other alkaloids such as caffeine.


In some embodiments, the active constituent is an olfactory active constituent and may be selected from a “flavor” and/or “flavorant” which, where local regulations permit, may be used to create a desired taste, aroma or other somatosensorial sensation in a product for adult consumers. In some instances such constituents may be referred to as flavors, flavorants, cooling agents, heating agents, or sweetening agents. They may include naturally occurring flavor materials, botanicals, extracts of botanicals, synthetically obtained materials, or combinations thereof (e.g., tobacco, cannabis, licorice (liquorice), hydrangea, eugenol, Japanese white bark magnolia leaf, chamomile, fenugreek, clove, maple, matcha, menthol, Japanese mint, aniseed (anise), cinnamon, turmeric, Indian spices, Asian spices, herb, wintergreen, cherry, berry, red berry, cranberry, peach, apple, orange, mango, clementine, lemon, lime, tropical fruit, papaya, rhubarb, grape, durian, dragon fruit, cucumber, blueberry, mulberry, citrus fruits, Drambuie, bourbon, scotch, whiskey, gin, tequila, rum, spearmint, peppermint, lavender, aloe vera, cardamom, celery, cascarilla, nutmeg, sandalwood, bergamot, geranium, khat, naswar, betel, shisha, pine, honey essence, rose oil, vanilla, lemon oil, orange oil, orange blossom, cherry blossom, cassia, caraway, cognac, jasmine, ylang-ylang, sage, fennel, wasabi, piment, ginger, coriander, coffee, hemp, a mint oil from any species of the genus Mentha, eucalyptus, star anise, cocoa, lemongrass, rooibos, flax, Ginkgo biloba, hazel, hibiscus, laurel, mate, orange skin, rose, tea such as green tea or black tea, thyme, juniper, elderflower, basil, bay leaves, cumin, oregano, paprika, rosemary, saffron, lemon peel, mint, beefsteak plant, curcuma, cilantro, myrtle, cassis, valerian, pimento, mace, damien, marjoram, olive, lemon balm, lemon basil, chive, carvi, verbena, tarragon, limonene, thymol, camphene), flavor enhancers, bitterness receptor site blockers, sensorial receptor site activators or stimulators, sugars and/or sugar substitutes (e.g., sucralose, acesulfame potassium, aspartame, saccharine, cyclamates, lactose, sucrose, glucose, fructose, sorbitol, or mannitol), and other additives such as charcoal, chlorophyll, minerals, botanicals, or breath freshening agents. They may be imitation, synthetic or natural ingredients or blends thereof. They may be in any suitable form, for example, liquid such as an oil, solid such as a powder, or gasone or more of extracts (e.g., licorice, hydrangea, Japanese white bark magnolia leaf, chamomile, fenugreek, clove, menthol, Japanese mint, aniseed, cinnamon, herb, wintergreen, cherry, berry, peach, apple, Drambuie, bourbon, scotch, whiskey, spearmint, peppermint, lavender, cardamom, celery, cascarilla, nutmeg, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, cassia, caraway, cognac, jasmine, ylang-ylang, sage, fennel, piment, ginger, anise, coriander, coffee, or a mint oil from any species of the genus Mentha), flavor enhancers, bitterness receptor site blockers, sensorial receptor site activators or stimulators, sugars and/or sugar substitutes (e.g., sucralose, acesulfame potassium, aspartame, saccharine, cyclamates, lactose, sucrose, glucose, fructose, sorbitol, or mannitol), and other additives such as charcoal, chlorophyll, minerals, botanicals, or breath freshening agents.
