Patent Description:
Electronic aerosol provision systems such as electronic cigarettes (e-cigarettes) generally contain aerosolisable material, such as a reservoir of fluid or liquid containing a formulation, typically but not necessarily including nicotine, or a solid material such a tobacco-based product, from which a vapour/aerosol is generated for inhalation by a user, for example through heat vaporisation. Thus, an aerosol provision system will typically comprise a vaporiser, e.g. a heating element, arranged to vaporise a portion of aerosolisable material to generate a vapour.

Once a vapour has been generated, the vapour may be passed through flavouring material to add flavour to the vapour, after which the (flavoured) vapour may be then delivered to a user via a mouthpiece from the aerosol provision system.

A potential drawback of existing aerosol provision systems is that the aerosolisable material and the flavouring material may be provided in differing amounts as part of different consumables. That being the case, there is the potential for one of the aerosolisable material or the flavouring material to run out or become depleted whilst the other material is still in plentiful supply. A further potential drawback of existing aerosol provision systems is that they may not be the most compact, and/or environmentally friendly.

It is common for aerosol provision systems to comprise a modular assembly, often having two main functional parts, namely a control unit and disposable / replaceable consumable part.

Various approaches are described herein which seek to help address or mitigate some of the issues discussed above.

<CIT> discloses an aerosol provision (AP) system (<NUM>) comprising a consumable (<NUM>) comprising a plurality of aerosol generating material portions and an aerosol generator (<NUM>) operable to generate an aerosolised payload by providing a predetermined heating profile to at least one of the plurality of aerosol generating material portions.

The present invention provides a consumable part for use in an aerosol provision system and an aerosol provision system comprising the consumable part as claimed.

It will be appreciated that features and aspects of the invention described above in relation to the various aspects of the invention are equally applicable to, and may be combined with, embodiments of the invention according to other aspects of the invention as appropriate, and not just in the specific combinations described herein.

The present disclosure relates to non-combustible aerosol provision systems, which may also be referred to as aerosol provision systems, such as e-cigarettes. According to the present disclosure, a "non-combustible" aerosol provision system is one where a constituent aerosolisable material of the aerosol provision system (or component thereof) is not combusted or burned in order to facilitate delivery to a user. Aerosolisable material, which also may be referred to herein as aerosol generating material or aerosol precursor material, is material that is capable of generating aerosol, for example when heated, irradiated or energized in any other way.

Throughout the following description the term "e-cigarette" or "electronic cigarette" may sometimes be used, but it will be appreciated this term may be used interchangeably with aerosol provision system / device and electronic aerosol provision system / device. An electronic cigarette may also known as a vaping device or electronic nicotine delivery system (END), although it is noted that the presence of nicotine in the aerosolisable material is not a requirement.

In some embodiments, the non-combustible aerosol provision system is a hybrid system to generate aerosol using a combination of aerosolisable materials, one or a plurality of which may be heated. In some embodiments, the hybrid system comprises a liquid or gel aerosolisable material and a solid aerosolisable material. The solid aerosolisable material may comprise, for example, tobacco or a non-tobacco product.

Typically, the non-combustible aerosol provision system may comprise a consumable part and a device which is configured to releasably engage with the consumable part.

The aerosol provision system may be provided with a means for powering a vaporiser therein, and there may be provided an aerosolisable material transport element for receiving the aerosolisable material that is to be vaporised. The aerosol provision system may also be provided with a reservoir for containing aerosolisable material, and in some embodiments a further reservoir for containing flavouring material for flavouring a generated vapour from the aerosol provision system.

In some embodiments, the vaporiser may be a heater/heating element capable of interacting with the aerosolisable material so as to release one or more volatiles from the aerosolisable material to form a vapour/aerosol. In some embodiments, the vaporiser is capable of generating an aerosol from the aerosolisable material without heating. For example, the vaporiser may be capable of generating a vapour/aerosol from the aerosolisable material without applying heat thereto, for example via one or more of vibrational, mechanical, pressurisation or electrostatic means.

In some embodiments, the substance to be delivered may be an aerosolisable material which may comprise an active constituent, a carrier constituent 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 aerosolisable 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, theine, a vitamin such as B6 or B12 or C, melatonin, a cannabinoid, or a constituent, derivative, or combinations thereof. 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, or mixtures thereof.

In some embodiments, the active constituent is an olfactory active constituent and may be selected from a "flavour" and/or "flavourant" 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 flavours, flavourants, flavouring material, cooling agents, heating agents, and/or sweetening agents. They may include naturally occurring flavour 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), flavour 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), flavour 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, oil, liquid, or powder.

In some embodiments, the flavouring material (flavour) may comprise menthol, spearmint and/or peppermint. In some embodiments, the flavour comprises flavour components of cucumber, blueberry, citrus fruits and/or redberry. In some embodiments, the flavour comprises eugenol. In some embodiments, the flavour comprises flavour components extracted from tobacco. In some embodiments, the flavour may comprise a sensate, which is intended to achieve a somatosensorial sensation which are usually chemically induced and perceived by the stimulation of the fifth cranial nerve (trigeminal nerve), in addition to or in place of aroma or taste nerves, and these may include agents providing heating, cooling, tingling, numbing effect. A suitable heat effect agent may be, but is not limited to, vanillyl ethyl ether and a suitable cooling agent may be, but not limited to eucalyptol, WS-<NUM>.

The carrier constituent may comprise one or more constituents capable of forming an aerosol. In some embodiments, the carrier constituent may comprise one or more of glycerine, glycerol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, <NUM>,<NUM>-butylene glycol, erythritol, meso-Erythritol, ethyl vanillate, ethyl laurate, a diethyl suberate, triethyl citrate, triacetin, a diacetin mixture, benzyl benzoate, benzyl phenyl acetate, tributyrin, lauryl acetate, lauric acid, myristic acid, and propylene carbonate.

The one or more other functional constituents may comprise one or more of pH regulators, colouring agents, preservatives, binders, fillers, stabilizers, and/or antioxidants.

As noted above, aerosol provision systems (e-cigarettes) often comprise a modular assembly including both a reusable part (device) and a replaceable consumable (cartridge) part. Devices conforming to this type of two-part modular configuration may generally be referred to as two-part devices. It is also common for electronic cigarettes to have a generally elongate shape. For the sake of providing a concrete example, certain embodiments of the disclosure described herein comprise this kind of generally elongate two-part device employing consumable parts. However, it will be appreciated the underlying principles described herein may equally be adopted for other electronic cigarette configurations, for example modular devices comprising more than two parts, as devices conforming to other overall shapes, for example based on so-called box-mod high performance devices that typically have a more boxy shape.

From the forgoing therefore, and with reference to <FIG>, there is shown a consumable part <NUM>, for use in an aerosol provision system, in accordance with certain embodiments of the disclosure. Terms concerning the relative location of various aspects of the consumable part <NUM> (e.g. terms such as upper, lower, above, below, top, bottom etc.) are used herein with reference to the orientation of the consumable part <NUM> as shown in <FIG> (unless the context indicates otherwise). However, it will be appreciated this is purely for ease of explanation and is not intended to indicate there is any required orientation for the consumable part <NUM> in use.

With the above in mind, <FIG> illustrates the consumable part <NUM>, which comprises a first reservoir <NUM> for containing aerosolisable material; and a second reservoir <NUM> for containing flavouring material. Notionally, the first reservoir <NUM> may be at least partly separated from the second reservoir.

In accordance with some embodiments, the consumable part <NUM> may comprise an aerosolisable material transport element <NUM> for receiving the aerosolisable material from the first reservoir <NUM>, wherein the aerosolisable material transport element <NUM> is configured to deliver vaporised aerosolisable material, using the aerosolisable material deriving from the first reservoir <NUM>, into the second reservoir <NUM>. With reference to the embodiment shown in <FIG>, the aerosolisable material transport element <NUM> may comprise any material that can effectively draw aerosolisable material from the first reservoir therein, for vaporising in the aerosolisable material transport element <NUM> as will be described. In that respect for instance, and in accordance with some embodiments, the aerosolisable material transport element <NUM> may comprise a wick, such as in some particular embodiments a mesh; a cotton wick and/or a wick made of another fibrous material(s), i.e. a fibrous wick.

In accordance with some embodiments, such as those shown in <FIG>, the aerosolisable material transport element <NUM> may at least partly separate the first reservoir <NUM> from the second reservoir <NUM>. In such arrangements therefore, both the first reservoir <NUM> (for containing the aerosolisable material), and the second reservoir <NUM> (for containing the flavouring material) are located in the same consumable part <NUM>, which helps to keep the consumable part <NUM> (and any aerosol provision system in which it is used) more compact. Through appropriate sizing of the first and second reservoirs <NUM>;<NUM> as well, placing both the first and second reservoir <NUM>;<NUM> in the same consumable part <NUM> can assist with better ensuring that the aerosolisable material and the flavouring material run out at the same time.

In that regard as well, it has been found that flavouring material from the second reservoir <NUM> may deplete at a quicker rate than the rate of depletion of any aerosolisable material in the first reservoir <NUM>. That being the case, and in accordance with some embodiments, the first reservoir <NUM> may be sized to contain, and/or may comprise, a first predetermined amount of aerosolisable material, and the second reservoir <NUM> may be sized to contain, and/or may comprise, a second predetermined amount of flavouring material, such that during the operation of the consumable part, the first predetermined amount of aerosolisable material and the second predetermined amount of flavouring material may be configured to be depleted at the same time. In that regard therefore, and in accordance with some embodiments, the second reservoir <NUM> may comprise a larger volumetric capacity than the volumetric capacity of the first reservoir <NUM>. As to an approximate size for the first and second reservoir <NUM>;<NUM>, in accordance with some embodiments, the first reservoir and/or second reservoir <NUM>;<NUM> may comprise a volumetric capacity which is no more than <NUM>, no more than <NUM>, and/or no more than <NUM>. Such capacities are particularly suited in more portable/handheld embodiments where the consumable part is intended to be used in portable/handheld aerosol provision system.

From the foregoing therefore, described is a consumable part <NUM> for use in an aerosol provision system which conveniently contains both the first reservoir <NUM> and the second reservoir <NUM> in the same consumable part.

As will be described, during the operation of the consumable part <NUM>, aerosolisable material from the first reservoir <NUM> is ultimately configured to be turned into a vapour by some sort of vaporiser. In accordance with some embodiments, the vaporiser may be (permanently) located in the consumable part <NUM>, such as in some particular embodiments located next to, or near, any aerosolisable material transport element <NUM> located in the consumable part <NUM>. In other embodiments however, the vaporiser <NUM> may form part of a device <NUM> to which the consumable part <NUM> is releasably engageable with (e.g. as will be described, and as is shown, with reference to the embodiments shown in <FIG> and/or <FIG>). That being the case, and in accordance with some embodiments, the consumable part <NUM> may be provided with a first access port <NUM> for allowing access to the first reservoir <NUM> (as illustrated in the embodiment of <FIG>). The exact type/structure of the first access port <NUM> may appreciably vary depending on the intended application of the consumable part <NUM>. For instance, in accordance with some embodiments, the first access port <NUM> may comprise a valve (such as in some particular embodiments thereof a duckbill valve, a one-way valve, and/or a ball valve) for better allowing fluid to only pass into, but not out from, the first reservoir <NUM>. In some embodiments, the first access port <NUM> may comprise a pierceable membrane (which might comprise a film, and/or possibly made of any combination of paper/cardboard/plastic/metal). In this way, when the piereceable membrane is pierced, the first access port <NUM> may be irreversibly opened, such that the first access port is single-use.

Turning to the second reservoir <NUM>, and in accordance with some embodiments, the consumable part may comprise a second access port <NUM> for allowing access to the second reservoir <NUM>. As with any present first access port <NUM>, the exact type/structure of the second access port <NUM> may vary depending on the intended application of the consumable part <NUM>. For instance, in accordance with some embodiments, the second access port <NUM> may comprise a valve (such as in some particular embodiments thereof a duckbill valve, a one-way valve, and/or a ball valve) for better allowing fluid (such as flavoured vapour) to only pass out-from, but not into from, the second reservoir <NUM>. In some embodiments, the second access port <NUM> may comprise a pierceable membrane. In this way, when the piereceable membrane is pierced, the second access port <NUM> may be irreversibly opened, such that the second access port <NUM> is single-use.

In terms of the geometry for the consumable part <NUM>, it will be appreciated that this may be varied depending on the application of the consumable part <NUM>. In accordance with some embodiments however, which may assist with providing a generally compact arrangement for the consumable part, and which may be better shaped to be more easily handled, the consumable part may comprise a first end <NUM>, and a second end <NUM> opposite the first end <NUM>, wherein the first reservoir <NUM> is located closer to the first end <NUM> than the second end <NUM>, and wherein the second reservoir <NUM> is located closer to the second end <NUM> than the first end <NUM>. Equally/alternatively, in accordance with some embodiments (such as those shown in <FIG> and <FIG>), the consumable part may define a cylindrical and/or elongate shape.

In accordance with some embodiments, such as those shown in <FIG>, where the consumable part comprises the first end <NUM> and the second end <NUM>, in some particular embodiments thereof, any first access port <NUM> may be conveniently located at the first end <NUM>. Equally/alternatively, the second access port <NUM> may be located at the second end <NUM>. In this way, the first and second access ports <NUM>;<NUM> may be suitably disposed away from each other, to help reduce any interference therebetween. For the sake of completeness however, it will be appreciated that any provided first access port need not expressly be located at a first end <NUM>, nor must any second access port <NUM> necessarily be located at a second end <NUM> of the consumable part. In that respect, in accordance with some embodiments, any provided first access port <NUM> might equally be located as part of a housing <NUM> of the consumable part, which houses the first reservoir <NUM> and the second reservoir <NUM>, and might be in fluid communication with first reservoir <NUM>. Equally, where such a housing <NUM> is employed, any provided second access port <NUM> may in accordance with some embodiments be located as part of the housing <NUM> and in fluid communication with the second reservoir <NUM>. From the foregoing therefore, it will be appreciated that depending on how any first access port <NUM> and second access port <NUM> are arranged (e.g. about the first end <NUM>, the second end <NUM>, and the housing <NUM>), in accordance with some embodiments, the first access port may be parallel with the second access port (as shown in the embodiments of <FIG>) or may be inclined at an angle to, or be perpendicular to, the second access port <NUM>.

As described above, in accordance with some embodiments, the consumable part may comprise a housing <NUM> in which the first reservoir <NUM> and the second reservoir <NUM> are located. Where such a housing is provided <NUM>, the first end <NUM> and the second <NUM> may be located at either end of the housing <NUM>. The aerosolisable material transport element <NUM>, where present, may be attached to the housing <NUM>, such as in some particular embodiments by a fastening means and/or by an adhesive. In some embodiments, to help reduce the overall number of components in the consumable part <NUM>, the aerosolisable material transport element <NUM> may be moulded as part of the housing so as to reduce the overall number of components in the consumable part <NUM>.

With respect to the materials used in the consumable part, it is envisaged that the material may vary depending on the application of the consumable part. In some embodiments, the first end <NUM>; the second end <NUM>; the first access port <NUM>; the second access port <NUM>; and/or the housing <NUM> may be made of any combination of paper, cardboard, plastic and/or silicone. Where a plastic or silicone is used, this may make the consumable part more rigid and weather resistant. Though in accordance with some, more environmentally friendly, embodiments, conveniently one or more of the above components from the consumable part may be made of paper and/or cardboard.

In that respect therefore, and in a particular embodiment, there may be provided a consumable part <NUM> for use in an aerosol provision system, wherein the consumable part <NUM> comprises: the first reservoir <NUM> for containing aerosolisable material; the second reservoir <NUM> for containing flavouring material; wherein the first reservoir <NUM> and the second reservoir <NUM> are located within a housing <NUM> of the consumable part <NUM>, wherein the housing <NUM> is made of paper or cardboard.

Particularly in embodiments where at least a portion <NUM> of the consumable part is made of paper and/or cardboard, such as the embodiment shown in <FIG>, in accordance with some embodiments thereof, to further improve the integrity of the consumable part <NUM> from moisture damage, the first reservoir <NUM> and/or the second reservoir <NUM> may comprise a fluid resistant coating/layer <NUM>. In some particular embodiments thereof, such a fluid resistant coating or fluid resistant layer <NUM> may be provided on an interior surface <NUM> of the housing <NUM>, an interior surface <NUM> of the first end <NUM> (or the first reservoir <NUM>), and/or an interior surface <NUM> of the second end <NUM> (or the second reservoir <NUM>).

Alternatively/additionally in accordance with some embodiments, the first reservoir <NUM> may comprise at least one interior resilient bag <NUM>, which is configured to accommodate the aerosolisable material whilst it is in the first reservoir <NUM>, and which is open at (and thus in fluid communication with) the aerosolisable material transport element <NUM>. Such an embodiment comprising the at least one interior resilient bag <NUM> is shown in the embodiment of <FIG>. In such embodiments, any provided housing <NUM> may better shield the resilient bag <NUM> from accidental knocks and/or perforations. Tying in with the above, where at least resilient bag <NUM> is provided, the bag(s) may define a recess <NUM> which is configured to accommodate a vaporiser <NUM> when the consumable part <NUM> is in use, as will be better explained with reference to the embodiments shown in <FIG> and <FIG>. Thus in accordance with these embodiments, when the consumable part <NUM> is in use, the resilient bag <NUM> may be configured to act as a separating member <NUM> for better ensuring that the vaporiser <NUM> vaporises aerosolisable material located in the aerosolisable material transport element <NUM> rather than aerosolisable material from the first reservoir <NUM>. For the sake of completeness, it will be appreciated that other forms of separating member <NUM> may be employed, other than the use of a resilient bag(s) <NUM> for inhibiting the vaporiser <NUM> from vaporising aerosolisable material located in the first reservoir <NUM>. In that respect for instance, the separating member <NUM> in accordance with some embodiments may comprise a partitioning wall between the recess <NUM> and the first reservoir <NUM>.

From the foregoing therefore, there has been described various embodiments of consumable part <NUM> which are intended to provide aerosolisable material from the first reservoir <NUM> therefrom, to the second reservoir <NUM> in which is provided a vapour that is then configured to be flavoured using the flavouring material in the second reservoir <NUM>, for delivering the flavoured vapour to a user for inhalation.

With the above in mind, and turning to <FIG>, the embodiments of consumable part <NUM> described herein have applications for use with a device <NUM> from an aerosol provision system, as will now be described. In that respect therefore, described herein is also an aerosol provision system comprising the consumable part <NUM> as described in any of the above embodiments, and a device <NUM> which is configured to releasably engage with the consumable part <NUM>, wherein the device <NUM> comprises a vaporiser <NUM> for generating a vapour from the aerosolisable material in the aerosolisable material transport element <NUM>.

The device <NUM> as described above may comprise a number of different shapes and sizes, depending on the embodiment. In accordance with some embodiments, the device <NUM> may be portable and/or handheld (such as the embodiment shown in <FIG>), and/or may comprise a recess or slot <NUM> for releasably accommodating the consumable part <NUM>. In accordance with some embodiments, the device <NUM> may comprise a lid portion <NUM> for holding the consumable part <NUM> in the recess or slot <NUM> when the consumable part <NUM> is in use. Such a latter embodiment is illustrated in the embodiment of <FIG>.

Whatever the principal construction of the device <NUM>, where the device <NUM> comprises the vaporiser <NUM>, the vaporiser <NUM> may be configured to be inserted into the first reservoir <NUM> for generating the vapour from the aerosolisable material in the aerosolisable material transport element <NUM> (as shown with reference to the embodiments illustrated at <FIG> and <FIG>). In some particular embodiments, to help better locate the vaporiser <NUM> proximal the aerosolisable material transport element <NUM> when the consumable part <NUM> is in use, the vaporiser <NUM> may be located on a probe <NUM> which is configured to be inserted, through the first access port <NUM>, into the first reservoir <NUM> for generating the vapour from the aerosolisable material in the aerosolisable material transport element <NUM>. In a particular embodiment, the vaporiser may be located at least partially at a tip <NUM> of the probe <NUM>, to maximise the proximity of the vaporiser <NUM> to any aerosolisable material transport element <NUM> located in the consumable part.

As part of any operation of the device <NUM>, there may also be provided an air inlet channel <NUM> in the device <NUM> which is configured to supply air into the consumable part <NUM>. In accordance with some embodiments, the air inlet channel <NUM> may be at least partly located as part of a probe which is configured to be inserted into the first reservoir <NUM>. In that respect, and in accordance with some embodiments, said probe may be the probe <NUM>, with the air inlet channel <NUM> at least partly extending through the probe <NUM>, as shown for instance in the embodiment of <FIG>. Appreciably, any provided probe in which the air inlet channel <NUM> is at least partly located need not necessarily be the probe <NUM>. In that respect, any such probe which is configured to be inserted into the first reservoir <NUM> could instead represent a second probe (not shown in the Figures) which is separate to, and/or independently operated from, the probe <NUM>.

For the sake of completeness as well, it will be appreciated that any provided air inlet channel <NUM> need not necessarily be located as part of a probe which is configured to be inserted into the first reservoir <NUM>. Indeed, the air inlet channel <NUM> from the device <NUM> could be configured in a number of different ways such that is configured to allow air to enter the consumable part <NUM> when the device <NUM> is engaged with the consumable part <NUM>. In that respect for instance, in accordance with some very particular embodiments, the air inlet channel <NUM> from the device <NUM> may comprise a valve which is configured to open to allow air to enter the consumable part <NUM> when the device <NUM> is engaged with the consumable part <NUM>. Equally in accordance with some embodiments, the consumable part <NUM> may comprise an air inlet port which is configured to for operating, and/or aligning with, the air inlet channel <NUM> from the device <NUM> when the device <NUM> is engaged with the consumable part <NUM>.

In accordance with some embodiments, any provided probe <NUM> may comprise a seal <NUM> for engaging with the first access port <NUM> when the probe is inserted, through the first access port <NUM>, into the first reservoir <NUM>. In this way, the seal <NUM> may better assist with the reduction of leakage of aerosolisable material through the first access port <NUM>.

To help deliver any flavoured vapour from the second reservoir <NUM> to a user of the device <NUM>, in accordance with some particular embodiments, the device <NUM> may further comprise a mouthpiece <NUM> for receiving vaporised aerosolisable material located in the second reservoir <NUM>. In accordance with some particular embodiments thereof, and where the second access port <NUM> is employed, at least a portion <NUM> of the mouthpiece <NUM> may be configured to be inserted, through the second access port <NUM>, into the second reservoir <NUM> for allowing vaporised aerosolisable material located in the second reservoir <NUM> to pass through into the mouthpiece. In this way, the second access port <NUM> is only accessed when the device <NUM> is engaged with the consumable part, which assists with preventing inadvertent leakage of vapour from the second reservoir <NUM> through the second access port <NUM>. For the sake of completeness however, it is be noted that the device <NUM> need not expressly comprise the mouthpiece <NUM>, noting in some embodiments any provided second access port <NUM> (e.g. when it comprises a pierceable membrane) could instead simply be opened/pierced by the user just prior to use of the consumable part, and the user then simply place their mouth over the opened/pierced second access port <NUM>.

Accordingly, there has been described a consumable part for use in an aerosol provision system, wherein the consumable part comprises:.

There has also been described a consumable part <NUM> for use in an aerosol provision system. The consumable part comprises a first reservoir <NUM> for containing aerosolisable material, and a second reservoir <NUM> for containing flavouring material. The consumable part <NUM> also comprises an aerosolisable material transport element <NUM> for receiving the aerosolisable material from the first reservoir <NUM>. The aerosolisable material transport element at least partly separates the first reservoir <NUM> from the second reservoir <NUM>, and the aerosolisable material transport element <NUM> is configured to deliver vaporised aerosolisable material into the second reservoir <NUM>.

There has also been described a consumable part <NUM> for use in an aerosol provision system. The consumable part <NUM> comprises a first reservoir <NUM> for containing aerosolisable material, and a second reservoir <NUM> for containing flavouring material. The consumable part <NUM> also comprises a first access port <NUM>, comprising a pierceable membrane, for allowing access to the first reservoir. The first reservoir <NUM> and the second reservoir <NUM> are located within a housing <NUM> of the consumable part <NUM>, wherein the housing <NUM> is made of paper or cardboard. This may serve to make the consumable part <NUM> more environmentally friendly and easier to recycle.

In order to address various issues and advance the art, this disclosure shows by way of illustration various embodiments in which the claimed invention(s) may be practiced. The advantages and features of the disclosure are of a representative sample of embodiments only, and are not exhaustive and/or exclusive. They are presented only to assist in understanding and to teach the claimed invention(s).
