Description

Aerosol supply system

Technical Field

The present disclosure relates to aerosol delivery systems such as, but not limited to, nicotine delivery systems (e.g., electronic cigarettes, etc.).

Background

Electronic aerosol supply systems such as electronic cigarettes (e-cigarettes) typically contain an aerosolizable material, such as a reservoir of a fluid or liquid containing a formulation, typically but not necessarily including nicotine, or a solid material, such as a tobacco-based product, from which a vapor/aerosol is generated for inhalation by a user, for example by thermal evaporation. Thus, the aerosol supply system will typically comprise a vaporiser (e.g. a heating element) arranged to vaporise a portion of the vaporisable material to generate the vapour.

Once the vapor has been generated, the vapor may be passed through a flavoring material to add flavoring to the vapor, after which the (flavored) vapor may then be delivered from the aerosol supply system to the user via the mouthpiece.

Aerosol supply systems typically comprise a modular assembly, typically having two main functional parts, namely a control unit/body, and a disposable/replaceable consumable part.

A potential drawback of existing aerosol supply systems is that aerosolizable material from the consumable part leaks into the control unit/body part. Such leakage may be disadvantageous because it may interfere with the effective operation of the aerosol supply system and reduce the operational lifetime of the aerosol supply system. Another potential disadvantage of existing aerosol supply systems is the inefficient vaporization of the aerosolizable material therefrom.

Accordingly, various approaches are described herein that seek to help solve or mitigate some of the problems discussed above.

The present disclosure relates to non-combustible aerosol supply systems (which may also be referred to as aerosol supply systems), such as electronic cigarettes. According to the present disclosure, a "non-combustible" aerosol supply system is an aerosol supply system in which the component aerosol supply system (or a component thereof) is delivered to a user without burning or igniting the aerosolizable material. An aerosolizable material (which may also be referred to herein as an aerosol generating material or aerosol precursor material) is a material that is capable of generating an aerosol, for example, when heated, irradiated, or energized in any other manner.

In the following description, the term "e-cigarette" or "e-cigarette" may be used at times, but it will be understood that this term may be used interchangeably with aerosol supply system/device and electronic aerosol supply system/device. The electronic cigarette may also be referred to as a vapor smoke device or electronic nicotine delivery system (END), but it should be noted that the presence of nicotine in the aerosolizable material is not required.

In some embodiments, the non-combustible aerosol supply system is a hybrid system that uses a combination of aerosolizable materials to generate an aerosol, wherein one or more of the aerosolizable materials may be heated. In some embodiments, the mixing system includes a liquid or gel aerosolizable material and a solid aerosolizable material. The solid aerosol-able material may comprise, for example, tobacco or a non-tobacco product.

The one or more other functional components may include one or more of a pH adjuster, a colorant, a preservative, a binder, a filler, a stabilizer, and/or an antioxidant.

As described above, aerosol delivery systems (e-cigarettes) typically comprise a modular assembly comprising both a reusable part (body/device) and a replaceable consumable (cartridge) part. Devices conforming to this type of two-piece modular configuration may generally be referred to as "two-piece" devices. Electronic cigarettes also typically have a generally elongated shape. To provide a specific example, certain embodiments of the present disclosure described herein include such a generally elongated two-piece device employing a consumable portion. However, it will be appreciated that the basic principles described herein may be equally applicable to other electronic cigarette configurations, such as modular devices comprising more than two parts, as well as devices conforming to other general shapes, such as those based on so-called box-mode high performance devices that typically have a box shape.

Thus, in accordance with the above, and with initial reference to fig. 1A-1C, in accordance with some embodiments, there is provided herein an aerosol supply system 1 comprising a cartridge 10 and a body 100. The body may include a recess/receptacle 102 for releasably receiving at least one surface 12 of the cartridge 10, potentially via a friction fit, wherein the at least one surface 12 of the cartridge 10 is devoid of any fluid inlet for delivering fluid into the cartridge 10. In this way, since at least one surface 12 of the cartridge 10 does not have any fluid inlet for delivering fluid into the cartridge 10, this helps to inhibit leakage of fluid from the cartridge 10 into the body 100 when the cartridge 10 is received in the body 100 (e.g., in the position of fig. 1B, with reference to the embodiment shown in fig. 1A-1C).

According to some of the above-described embodiments, the cartridge 10 may include a first end surface 14 configured to be releasably received in the recess 102 and a second end surface 16 opposite the first end surface 14 and configured to be located outside of the recess 102 when the first end surface 14 is releasably received in the recess 102. In some embodiments thereof, the at least one surface 12 may then comprise a first end surface 14 (e.g., as shown in the embodiments of fig. 1A-1C, wherein the first end surface 14 does not have any fluid inlet for delivering fluid into the cartridge 10).

To provide additional security to the cartridge 10 when used with the body 100, the cartridge may include a plurality of side surfaces 18 extending between the first end surface 14 and the second end surface 16, wherein at least one surface 12 includes a first portion 18A of the plurality of side surfaces 18. In this regard, since the at least one surface 12 includes the first portions 18A of the plurality of side surfaces 18, this facilitates better containment of more cartridges 10 in the body when the cartridges are in use. Thus, also in this regard, the first portion 18A of the plurality of side surfaces 18 then does not have any fluid inlet for delivering fluid into the cartridge 10, which further helps to inhibit leakage of fluid from the cartridge 10 into the body 100 (e.g., as shown in the embodiment of fig. 1A-1C, wherein the first portion 18A of the plurality of side surfaces 18 does not have any fluid inlet for delivering fluid into the cartridge 10).

Where there are multiple side surfaces 18, according to some embodiments thereof (such as the embodiments shown in fig. 1A-1C), the multiple side surfaces 18 may include a second portion 18B configured to be located outside of the recess 102 when the first end surface 14 is releasably received in the recess 102. Such a second portion 18B is best illustratively shown with reference to the embodiment shown in fig. 1C. For such a second portion 18B, in some embodiments thereof, the second portion 18 may include at least one air inlet 20 (or more than one air inlet) for delivering air into the cartridge 10. As will be described, each such air inlet is then configured to allow air to pass through the cartridge to pick up the vapour of the aerosolizable material for eventual inhalation by a user of the cartridge 10. In embodiments employing multiple air inlets, the multiple air inlets 20 may include a pair of air inlets on opposite side surfaces of the multiple side surfaces 18, according to some embodiments thereof (such as the embodiment shown in fig. 1C).

Continuing with the description of the cartridge 10, in some embodiments, to better allow a user to inhale any generated vapor from the cartridge 10, the cartridge may include a mouthpiece 22. The mouthpiece may include a portion of the second portion 18B and may include the second end surface 16 of the cartridge, for example, as shown in the embodiment of the cartridge in fig. 1A-1C. According to some embodiments employing a mouthpiece 22, any provided air inlet from the cartridge 10 may be located between the mouthpiece 22 and the first end surface 14. In some particular embodiments thereof, as shown in the embodiment of the cartridge in fig. 1C, each air inlet may be positioned adjacent to the mouthpiece 22.

Continuing with this embodiment in fig. 1C, according to some embodiments of the aerosol provision system 1 described herein, the body 100 may comprise a shroud 104 defining the recess 102, wherein the end 106 of the shroud 104 comprises at least one (or more) recessed portion 108, wherein each recessed portion 108 is configured to align with the air inlet 20 of the cartridge 10 when the at least one surface 12 of the cartridge 10 is releasably received in the recess 102. In this way, the recessed portion 108 may better protect the periphery of the air inlet 20 from accidental damage during use of the cartridge 10, which may otherwise affect the performance of the aerosol supply system 1. In very particular embodiments, and where a mouthpiece 22 is employed, the mouthpiece 22 may be configured to be adjacent to the at least one recessed portion 108 when the at least one surface 12 of the cartridge 10 is releasably received in the recess 102. In such a particular embodiment, this better ensures a convenient fit of the mouthpiece 22 with respect to the at least one recessed portion 108 by positioning the air inlets 20 with respect to the mouthpiece 22 and the at least one recessed portion 108 in such a way that the air inlets 20 are located outside the recess 102 and in such a way that the periphery of each air inlet 20 is better protected from accidental damage during use of the cartridge 10. Also, it is convenient to locate the air inlet 20 in this position to better ensure that the air inlet 20 is not accidentally covered by the user's hand during the time the user is holding the body 100, noting that it is unlikely that the user will grasp the body at an area near the mouthpiece 22. Thus, repositioning each air inlet 20 in this position better ensures that the air inlet 22 remains unobstructed during use of the aerosol provision system 1 and is therefore fully operational.

Thus, with the foregoing in mind, and in accordance with some embodiments described herein, there may also be provided an aerosol supply system 1 comprising a cartridge 10 comprising a mouthpiece 22; and a body comprising a recess for releasably receiving the at least one surface 12 of the cartridge 10, wherein the body comprises a shroud 104 defining the recess 102, wherein an end 106 of the shroud 104 comprises at least one recessed portion 108, wherein each recessed portion 108 is configured to align with the air inlet 20 of the cartridge 10 when the at least one surface 12 of the cartridge 10 is releasably received in the recess 102. In some embodiments thereof, the mouthpiece 22 may then be configured to be adjacent to the at least one recessed portion 108 when the at least one surface 12 of the cartridge 10 is releasably received in the recess 102.

To the extent any mouthpiece may be employed, it will be appreciated that this may conveniently function to facilitate engagement with the recess when the cartridge 10 is engaged with the body 100. Also in this regard, it will be appreciated that the cartridges and corresponding recesses/receptacles may take on non-circular and/or elongate cross-sections to facilitate easier alignment of the cartridges relative to the recesses/receptacles. Such a shape may also help to provide a mouthpiece shape, potentially also via the use of an inclined side surface, and thus is particularly well configured for wrapping the user's lips around, allowing the user to more effectively seal their lips around any aperture at the tip of the mouthpiece through which vaporized aerosolizable material may be delivered into the user's mouth.

Also, in accordance with at least some embodiments, it is to be appreciated that the outer surface of the mouthpiece (such as the outer surface of the angled side surface of the mouthpiece) may be opaque in accordance with some embodiments. This may facilitate the inability of the user to view the internal contents of the cartridge in use (as shown in the embodiments of the drawings), such as any vapor plume formed inside the cartridge 100, which may otherwise raise some potential user concerns. Also in this regard, and according to some embodiments such as those shown in the figures, the mouthpiece and/or the angled side surface may be black and/or matt to better allow any indicia (such as lipstick or some other stain) on the mouthpiece to be more easily removed and/or unnoticed.

Thus, as can be seen from the foregoing comments, another aspect of the present disclosure is in relation to the particularly effective geometry of the mouthpiece described herein, which may be obviously used with any type of aerosolizable material, such as solid aerosolizable material (e.g., potentially including tobacco) and/or liquid aerosolizable material (and in the latter case, then potentially using any of the aerosolizable material transport elements 34 described herein).

Similarly, and with the foregoing in mind, in accordance with some embodiments described herein, there may also be provided a cartridge 10 for use in an aerosol supply system 1, wherein the cartridge 10 comprises: the first end surface 14, being devoid of any fluid inlet for delivering fluid into the cartridge 10; a second end surface 16 opposite the first end surface 14; a plurality of side surfaces 18 extending between the first end surface 14 and the second end surface 16, wherein the plurality of side surfaces 18 include at least one air inlet 20 for delivering air into the cartridge; a mouthpiece 22; wherein each air inlet 20 is positioned adjacent to the mouthpiece 22 and between the mouthpiece 22 and the first end surface 14.

According to at least some of the above embodiments, at least one surface 12 of the cartridge 10 may be devoid of any fluid inlet for delivering fluid into the cartridge 10, thereby helping to inhibit leakage of aerosolizable material from the cartridge 10 into the body. In such a case, in such an embodiment, the fluid inlet may comprise an air inlet 20 to better inhibit any residual moisture from any air passing through the air inlet 20 from passing through to the body 100, and/or may comprise an inlet for the aerosolizable material (to better prevent any vaporized aerosolizable material from reaching the body 100).

Thus, in light of the foregoing, the above embodiments describe embodiments that better help inhibit leakage of the aerosolizable material from the cartridge 10 into the body 100.

Turning to other aspects of the aerosol provision system 1 described herein, according to some embodiments thereof, the cartridge may be provided with a first reservoir 30 for containing the aerosolizable material, and in some embodiments, the aerosol provision system 1 may also be provided with an evaporator 32 for evaporating the aerosolizable material from the first reservoir 30. In some embodiments thereof, and in general terms, air may then be configured to pass through the air inlet 20, through the evaporator 32 (where vapor of the aerosolized material may be formed), and finally out of the mouthpiece 22 for inhalation by a user during use of the aerosol supply system 1, as will be described.

According to some more specific embodiments (such as the embodiments shown in fig. 2A-3D), the cartridge 10 may comprise an aerosolizable material transport element 34 for receiving the aerosolizable material from the first reservoir 30, wherein the evaporator 32 is configured to vaporize the aerosolizable material in the aerosolizable material transport element 34.

To add flavouring material to any vapour provided to the user, according to some embodiments, the cartridge according to some embodiments may also be provided with a second reservoir 36 for holding flavouring material. Where such a second reservoir 36 is employed, the second reservoir may be located upstream of any provided vaporizer 32 (so as to deliver the flavoring material before any aerosolizable material is vaporized), or according to some embodiments may be configured to add the flavoring material from the first reservoir 30 to the aerosolizable material before the aerosolizable material is vaporized by the vaporizer 32. However, in other embodiments (such as the embodiments shown in fig. 2A-3D), the second reservoir 36 may be configured to receive vaporized aerosolizable material from the evaporator 32. With respect to any provided spatial arrangement of the second reservoir 36 relative to the first reservoir 30, it will be appreciated that the second reservoir 36 may be located in a number of different positions in the cartridge. However, according to some embodiments, to help provide a compact arrangement of the cartridge 10, the first reservoir 30 may be located between the second reservoir 36 and the first end surface 14. Likewise, and/or alternatively, in some embodiments, the second reservoir 36 may be surrounded by the mouthpiece 22 (where employed), and/or may be configured to deliver vaporized, flavoured, aerosolizable material from the outlet 37 of the cartridge 10/aerosol supply system 1. In some very specific embodiments, such an outlet 37 may be located in the second end surface, or may be located in a recess/aperture 39 extending from the second end surface 16 (as in the embodiments shown in fig. 2A-3D). However, for the avoidance of any doubt, it will be appreciated that any provided outlet 37 may be located at a variety of different positions on the cartridge 10, depending on the exact shape/configuration of cartridge 10 employed.

Likewise, where any second reservoir 36 is employed, it will be further understood that the second reservoir 36 may include any combination of flavoring materials, such as any of the flavoring materials previously described. Although according to some particular embodiments the flavoring material may include tobacco and/or nicotine.

According to some embodiments (such as the embodiments shown in fig. 2A-3D), removed from any provided second reservoir 36, and diverted how in use air/vapor is directed through the cartridge 10, the cartridge 10 may include a first channel 38 for receiving air from the air inlet 20 of the cartridge 10. The cartridge 10 may then include a second channel 40 downstream of the first channel 38 and configured to receive vaporized aerosolizable material from the evaporator 32 (as will be described). In some embodiments thereof, to help provide a compact arrangement of the cartridge 10, the first channel 38 may be parallel to the second channel 40, and the first channel 38 may be located outside of the second channel 40. As such and/or alternatively, in some embodiments, the first channel 38 may be positioned closer to the plurality of side surfaces 18 than the second channel 40.

With respect to any embodiment in which the first channel 38 is parallel to the second channel 40, in these embodiments, and potentially other embodiments, air may be configured to flow along the first channel 38 in a first direction A1, and vaporized aerosolizable material from the evaporator 32 is configured to flow along the second channel 40 in a second direction A2, wherein the second direction A2 is opposite the first direction A1. For example, in the embodiment of the cartridge shown in fig. 3A to 3C, these first and second directions A1 and A2 are shown. In such embodiments, a change in direction from the first direction A1 to the second direction A2 may increase the turbidity (turbidness) of air passing through the evaporator 32 and/or any provided aerosolizable material transport element 34, which may each/all be located at the (downstream) end 38A of the first channel 38 and at the (upstream) end 40A of the second channel 40. Such increased turbidity may then help to better form vapor and pass it through the second passage 40 in the second direction A2.

Continuing with the geometry of the second channel 40, according to some space-efficient embodiments, the second channel 40 may be located between the first end surface 14 and any provided second reservoir 36. Likewise/alternatively, the end of the second channel 40A may be positioned adjacent any provided aerosolizable material transport element 34 of the cartridge 10.

Turning to any provided features of the vaporizer 32 and/or the aerosolizable material transport element 34, the purpose of these features is to vaporize the aerosolizable material from the first reservoir 30 to produce a vaporized aerosolizable material that can be given to a user during use of the aerosol supply system 1. In this regard, any generated vaporized aerosolizable material may pass along the second channel 40 and then pass through the second reservoir and out the outlet 37.

Conceptually, the evaporator 32 may take a variety of different forms such that the evaporator may be configured to generate a vapor/aerosol from an aerosolizable material by applying heat thereto (e.g., via a heater/heating element) or not applying heat thereto (e.g., via one or more of vibration means, mechanical means, pressurizing means, or electrostatic means as previously described).

That is, according to some embodiments, the evaporator 32 may include a heating element 32A located in the body 100, and may be configured such that the evaporator 32 is located at least partially in the body 100 and at least partially in the cartridge 10, for example as shown in the embodiments in the figures. According to some particular embodiments thereof, the cartridge 10 may then include a thermally conductive surface 32B, which may be an external thermally conductive surface, for receiving heat from a heating element 32A located in the body 100; wherein the heat conducting surface 32B forms part of the evaporator 32.

Thus, according to the above-described embodiment, and also the particular embodiment shown in the accompanying drawings, the evaporator 32 can thus be formed of two parts—a first part of the heating element 32A located in the body 100; and a second portion in the form of a thermally conductive surface 32B in the cartridge 10. In this manner, the thermally conductive surface 32B is configured to contact the heating element 32A when at least one surface 12 of the cartridge 10 is releasably received in the recess 102 from the body 100. The provision of the two-part evaporator 32 provides a number of advantages, particularly in helping to keep at least one surface 12 of the cartridge 10 free of fluid inlets, to help inhibit leakage of the aerosolizable material from the cartridge 10 into the body 100. Furthermore, the separation of the evaporator 32 between the cartridge 10 and the body portion 100 provides an additional safety feature that prevents the evaporator 32 from operating when the cartridge 10 is separated from the body 100. By also positioning some of the evaporator 32 in the body 100, this also helps to reduce the number of components in the cartridge 10, which helps to note that in some embodiments, the cartridge may be configured to be consumable/disposable.

With the foregoing in mind and with the use of the (external) thermally conductive surface 32B, according to some embodiments thereof, the thermally conductive surface 32B may form part of a conductive member 46 (which may comprise a conductive plate or foil in some particular embodiments) of the cartridge 10, wherein the aerosolizable material transport element 34 is in contact with the conductive member 46. In this way, when the heating element 32A contacts the thermally conductive surface 32B, heat from the heating element 32A may then pass through the thermally conductive surface 32B, through the conductive member 46, and to the aerosolizable material transport element 34. Such an embodiment is shown in the embodiment of fig. 1C. In other words, according to some of the above embodiments and theoretically other embodiments, the aerosolizable material transport element 34 can be in contact with the conductive member 46 at a contact surface 48 with the conductive member 46, wherein the contact surface 48 is opposite and/or parallel to the (external) heat conducting surface 32B. In some embodiments (such as the embodiments shown in the figures), at least one of the contact surface 48 and the corresponding surface of the aerosolizable material transport element 34 in contact with the contact surface 48 may be planar.

As mentioned briefly above, the exact shape of any provided conductive member 46 may vary depending on its application in any provided aerosol supply system 1. Although according to some particular embodiments, the conductive member 46 may comprise a conductive plate or foil, and may be made of a thermally conductive material such as, but not limited to, metal. Likewise, where a conductive member 46 is employed, the conductive member 46 may define the first end surface 14 of the cartridge 10, according to some embodiments, as is the case in the embodiment of the cartridge 10 shown in the drawings. For the sake of completeness only, it is envisaged that the conductive member 46 may be attached to the cartridge 10 and/or with the aerosolizable material transport element 34. In this regard, and in accordance with some particular embodiments, for example, to better secure the conductive member 46 in place during use, the conductive member 46 may be attached to the cartridge 10 and/or the aerosolizable material transport element 34 via at least one of a crimping action, an adhesive, or a mechanical fastening means in accordance with some particular embodiments.

As described above, according to some embodiments, the conductive member 46 may include a conductive plate or foil. In this way, this may allow the conductive member 46 to be made particularly thin, which may help better ensure efficient heat transfer across the conductive member 46. In this regard, and according to some particular embodiments, the thickness of any such conductive member 46 may be no greater than 5mm. In other additional/alternative embodiments, any such conductive member 46 may be between 0.5mm and 5mm thick, or between 1mm and 5mm thick, in order to achieve an optimal balance between providing a conductive member 46 that transfers heat particularly efficiently across its thickness, but is thick enough to better withstand any accidental perforation of the thickness of the conductive member 46.

With respect to the exact placement of the thermally conductive surface 32B (and/or the conductive member 46), in particularly compact and space efficient embodiments, the second channel 40 may be located between any provided second reservoir 36 and the thermally conductive surface 32B (conductive member 46).

Thus, in light of the foregoing, certain embodiments of an aerosol provision system have been described above that employ a vaporizer 32 that is separate between the cartridge 10 and the body portion 100. In this case, and in accordance with some more general embodiments, the above disclosure may provide a cartridge 10 for use in an aerosol provision system 1 comprising a cartridge 10 and a body 100, wherein the cartridge 10 comprises an external heat conducting surface 32B for receiving heat from a heating element 32A located in the body 100.

Likewise, and in a general sense, the above disclosure may also provide an aerosol provision system 1 comprising: a cartridge 10 and a body 100, wherein the cartridge 10 includes an external thermally conductive surface 32B for receiving heat from a heating element 32A located in the body 100.

According to some embodiments, the aerosol provision system 1 described herein may be provided with an aerosolizable material transport element 34 for receiving an aerosolizable material, such as aerosolizable material from the first reservoir 30, moving away from the evaporator 32.

In general terms, the structure and composition of the aerosolizable material transport element 34 (also referred to as a wick) can be anything that is capable of properly drawing the aerosolizable material to a location where it can be vaporized by the vaporizer 32 during use of the aerosol supply system. Thus, in this regard, according to some embodiments, the aerosolizable material transport element 34 can include a porous material, a fibrous material, and/or a solid material. In some embodiments, the aerosolizable material transport element 34 can be made of cotton, or can be made of a ceramic material. Thus, the foregoing is understood, and at a general level, it will be appreciated that the specific structure and composition of the aerosolizable material transport element can be varied to best meet any intended application of the aerosol supply system 1.

As described above, according to some embodiments described herein, an aerosolizable material transport element 34 can be provided having a particular geometry, such as (but not limited to) the geometry shown in the embodiments of the cartridge 10 in the figures. Thus, in particular, and as will be described, an aerosolizable material transport element 34 for use in an aerosol provision cartridge 10 or an aerosol provision system 1 may be provided, wherein the aerosolizable material transport element 34 comprises a length L extending between a first end 50 of the aerosolizable material transport element 34 and a second end 52 of the aerosolizable material transport element. In some embodiments thereof, the cross-sectional area a of the aerosolizable material transport element 34 (which is orthogonal to the length L) may be configured to vary along the length L of the aerosolizable material transport element 34. For example, referring to the embodiment in fig. 2D, such an embodiment of an aerosolizable material transport element 34 may be best illustrated, wherein such an aerosolizable material transport element 34 is employed.

With respect to the aerosolizable material transport member 34 in which the cross-sectional area a of the aerosolizable material transport member 34 varies along the length L of the aerosolizable material transport member 34, this provides an aerosolizable material transport member 34 that can better and more efficiently direct the aerosolizable material therein from a location proximate to the first reservoir 30 to a location closer to the vaporizer 32 where the aerosolizable material can then be vaporized by the vaporizer 32. For the sake of completeness, with respect to cross-sectional area a, where the aerosolizable material transport element 34 splits into a plurality of cross-sectional areas at a given location along the length L of the aerosolizable material transport element 34, the cross-sectional area a along the length L at that axial location is interpreted as the sum of the plurality of cross-sectional areas in that axial direction (e.g., the sum of cross-sectional area a' and cross-sectional area a "of the aerosolizable material transport element 34 as shown in the embodiment of fig. 3B, which splits into two at an axial location along the length L of the aerosolizable material transport element 34).

It will be appreciated that the above, and in accordance with some embodiments thereof, as well as other embodiments of the aerosolizable material transport element 34 described herein, any provided aerosolizable material transport element can include a first leg portion 54 extending from the first end 50 and a second leg portion 56 extending from the second end 52, and a central body portion 58 located between the first leg portion 54 and the second leg portion 56. In some embodiments thereof, the central body portion may then include an aperture 60 extending through the thickness of the aerosolizable material transport element 34. The first function of the apertures 60 is to increase the exposed surface area of the aerosolizable material transport element 34, thereby increasing the amount of vaporized aerosolizable material that can be generated from the aerosolizable material transport element 34.

Thus, for a given size of aerosolizable material transport element 34, this increased surface area may also effectively allow for the use of smaller size aerosolizable material transport elements 34 than would otherwise be the case. The second function of the aperture is to allow heat from the evaporator 32 (such as the outer thermally conductive surface 32B) to better enter the second channel 40 and around the vicinity of the aerosolizable material transport element 34 to better ensure that it is properly heated for heating the aerosolizable material. According to such embodiments, the introduction of the aperture 60 may also advantageously help to better direct vaporized aerosolizable material from the aerosolizable material transport element 34 into and along the second channel 40 towards the outlet 37. This guiding effect can be seen by referring to the wavy arrow shown in fig. 3B and 3C, which is located near the opening 60 and extends towards the second channel 40. In particular embodiments that may additionally exhibit the above-described effects, any provided apertures 60 may extend through the thickness of the aerosolizable material transport element 34 in a direction A3 that is perpendicular or orthogonal to the length L of the aerosolizable material transport element 34, and/or parallel to the first direction A1; and/or parallel to the second direction A2.

To help provide a more consistent formation of vaporized aerosolizable material around any provided apertures 60, according to some embodiments, the apertures 60 may be cylindrical according to some particular embodiments, and/or include a uniform cross-section through the thickness of the aerosolizable material transport element 34.

According to some embodiments, such as the one shown in the figures, the conductive member 46 (where employed) may cover the end of the aperture 60, thereby better ensuring that any heat from the conductive member 46 is directed upwardly funneled through the aperture 60 so that it is better transferred into and around the aerosolizable material transport element 34 and into the second channel 40.

According to some embodiments, each leg portion 54 of the aerosolizable material transport element 34 is removed from any provided aperture 60 in the aerosolizable material transport element 34; 56 may be configured to be in fluid communication with the first reservoir 30 for receiving the aerosolizable material from the first reservoir 30. Such an embodiment is shown in the embodiment shown in fig. 3C. Thus, in such embodiments, the aerosolizable material from the first reservoir 30 may be effectively encouraged from each leg portion 54;56 to a central body portion 58 of the aerosolizable material transport element 34.

In combination with the above, and in accordance with some additional/alternative embodiments, the first channel 38 may include at least one orifice 64 in fluid communication with the second channel 40, wherein each orifice 64 is adjacent to the aerosolizable material transport element 34, and/or more particularly, the central body portion 58 of the aerosolizable material transport element (where a central body portion 58 is employed). In this way, air passing through the orifice 64 from the first passage may immediately impinge upon the aerosolizable material transport element, thereby maximizing the extent of vapor delivered into the air, which is then delivered to the second passage 40.

Also in this regard, and in order to better position the aerosolizable material transport element 34 alongside each aperture 64 (and to better prevent lateral movement of the aerosolizable material transport element 34 in use), and in order to assist in vaporization of the aerosolizable material from the aerosolizable material transport element 34, according to some embodiments, the aerosolizable material transport element 34 (or in some more particular embodiments, its central body portion 58) may include a recessed portion 66 for each respective aperture 64 that is positioned adjacent to its respective aperture 64, as shown in the embodiment of fig. 3B, for example. In this regard, by virtue of each recessed portion 66 creating a reduced width portion in the aerosolizable material transport element 34 in which the recessed portion 66 is located, it has surprisingly been found that this increases the efficiency with which the aerosolizable material transport element 34 vaporizes the aerosolizable material therefrom. Also in this regard, with the increased exposed surface area of the aerosolizable material moving member 34 created by each recessed portion 66, this can be used to increase the amount of vaporized aerosolizable material that can be generated from the aerosolizable material transporting member 34. Thus, for a given size of aerosolizable material transport element 34 (e.g., in the presence of any supply of apertures 60), this increased surface area may also effectively allow for smaller size of aerosolizable material transport element 34 than would otherwise be possible.

According to embodiments employing more recessed portions 66 (apertures 64), according to some particular embodiments thereof, a first recessed portion 66 on a first side of the aerosolizable material transport element 34, and a second recessed portion 66 on a second side of the aerosolizable material transport element 34 may be provided, wherein the first side is opposite the second side, as shown, for example, in the embodiment of fig. 3B. According to some very specific embodiments, the first and second sides of the aerosolizable material transport element 34 can be the first and second sides of the central body portion 58, as also shown in the specific embodiment of fig. 3B. In other words, according to some embodiments, the first and second sides of the aerosolizable material transport element 34 can be positioned adjacent to respective first and second apertures 64, 64 of the at least one aperture 64.

Continuing with the description of the apertures 64, according to some embodiments, each aperture 64 may extend in a direction A4 between the first channel 38 and the second channel 40 that is orthogonal to the first direction A1 and the second direction A2. This change in direction may help to increase the turbidity of the air passing through the evaporator 32 and/or any aerosolizable material transport element 34, thereby better helping the vapor to better form in the second direction A2 and through the second channel 40. Likewise, and according to some embodiments, each orifice 64 may extend in a direction A4 orthogonal to the length L of the aerosolizable material transport element. In this way, the control of air and aerosolizable material may be more efficiently spaced apart inside the cartridge 10 and, in theory, additionally allow the aerosolizable material transport element 34 to have an elongated/thin width, such as shown in the embodiment of the cartridge 10 shown in the drawings.

Thus, with the foregoing in mind, it can be seen that the above embodiments provide a unique design of the aerosolizable material transport element 34 that is both efficient and otherwise well suited for use in the aerosol provision cartridge 10 and/or the aerosol provision system 1. In fact, and for the avoidance of any doubt only, where any of the above-described aerosolizable material transport elements 34 are employed, it is envisaged that this may be used in any of the cartridges 10 or aerosol supply systems 1 described herein.
