Description

[Technical Field]

[0001] (Field) The present disclosure relates to aerosol delivery systems, including, but not limited to, nicotine delivery systems (e.g., e-cigarettes, etc.). [Background technology]

[0002] (background) Electronic aerosol delivery systems, such as electronic cigarettes (e-cigarettes), typically include an aerosolizable material, such as a fluid or liquid reservoir containing a solid material, such as a formulation (usually, but not necessarily, containing nicotine) or a tobacco-based product, that is vaporized, for example, by thermal vaporization, to produce a vapor / aerosol that is inhaled by a user. As such, an aerosol delivery system will typically include a vaporizer (e.g., a heating element) configured to vaporize a portion of the aerosolizable material to produce a vapor.

[0003] Once the vapor is generated, it may be flavored by passing it through a flavoring material, and then the (flavored) vapor may be delivered to the user from the aerosol delivery system through the mouthpiece.

[0004] Aerosol delivery systems typically comprise a modular assembly and often have two main functional components: a control unit / main body and a disposable / replaceable consumable component.

[0005] A potential drawback of existing aerosol delivery systems is leakage of aerosolizable material from consumable components into the control unit / main body. Such leakage can be disadvantageous because it can prevent the aerosol delivery system from operating efficiently and reduce the useful life of the aerosol delivery system. Another potential drawback of existing aerosol delivery systems is inefficient vaporization of the aerosolizable material.

[0006] Accordingly, various approaches are described herein that may help address or mitigate some of the problems mentioned above. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

[0013] (Detailed explanation) Aspects and features of particular examples and embodiments are discussed / described herein. Some aspects and features of particular examples and embodiments may be conventionally implemented and will not be discussed / described in detail for the sake of brevity. It should therefore be understood that unrecited aspects and features of the devices and methods discussed herein may be implemented in accordance with any conventional technology that implements such aspects and features.

[0014] The present disclosure relates to non-combustible aerosol delivery systems (sometimes referred to as aerosol delivery systems), such as e-cigarettes. According to the present disclosure, a "non-combustible" aerosol delivery system is one in which the aerosolizable material (or components thereof) of which it is composed is not burned or combusted to facilitate delivery to a user. An aerosolizable material (sometimes referred to herein as an aerosol-generating material or aerosol precursor material) is a material that can generate an aerosol when supplied with energy, for example, by heating, irradiation, or in any other manner.

[0015] Throughout the following description, the terms "e-cigarette" or "electronic cigarette" may be used interchangeably with aerosol delivery systems / devices and electronic aerosol delivery systems / devices. E-cigarettes are also known as vaping devices or electronic nicotine delivery systems (ENDs), although the presence of nicotine in the aerosolizable material is not a requirement.

[0016] In some embodiments, the non-combustible aerosol delivery system is a hybrid system that generates aerosols through a combination of aerosolizable materials, one or more of which may be heated. In some embodiments, the hybrid system includes liquid or gel aerosolizable materials as well as solid aerosolizable materials. The solid aerosolizable materials may include, for example, tobacco or non-tobacco products.

[0017] Generally, a non-flammable aerosol delivery system may include a consumable part and a device / body configured to releasably engage the consumable part.

[0018] The aerosol delivery system may be provided with means for powering an internal vaporizer and may be provided with an aerosolizable material transfer element for receiving the aerosolizable material to be vaporized. The aerosol delivery system may also be provided with a reservoir for containing the aerosolizable material and, in some embodiments, a separate reservoir for containing a flavoring material for flavoring the vapor produced from the aerosol delivery system.

[0019] In some embodiments, the vaporizer may be a heater / heating element that can interact with the aerosolizable material to release one or more volatile substances from the aerosolizable material to form a vapor / aerosol. In some embodiments, the vaporizer can generate an aerosol from the aerosolizable material without the application of heat. For example, the vaporizer may be capable of generating a vapor / aerosol from the aerosolizable material without the application of heat, for example, by one or more of vibrational, mechanical, pressurized, or electrostatic means.

[0020] In some embodiments, the substance to be delivered may be an aerosolizable material that may include an active constituent, a carrier constituent, and optionally one or more other functional constituents.

[0021] The active ingredient may include one or more physiologically and / or olfactorily active ingredients included in the aerosolizable material to achieve a physiological and / or olfactory response in the user.

These may include extracts (e.g., licorice, hydrangea, magnolia leaf, chamomile, fenugreek, clove, menthol, peppermint, aniseed, cinnamon, herbs, 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, bell pepper, ginger, etc.). The additives may be in any suitable form (e.g., liquid such as an oil, solid such as a powder, or gaseous) containing one or more of the following additives: citric acid, anise, coriander, coffee, or mint oil of any species of the genus Mentha), flavor enhancers, bitter taste receptor site blockers, sensory receptor site activators or stimulators, sugars and / or sugar substitutes (e.g., sucralose, acesulfame potassium, aspartame, saccharin, cyclamate, lactose, sucrose, glucose, fructose, sorbitol, or mannitol), and other additives such as charcoal, chlorophyll, minerals, botanicals, or breath fresheners. These may be imitation, synthetic, or natural ingredients, or mixtures thereof. These may be in any suitable form, e.g., oil, liquid, or powder.

[0023] In some embodiments, the flavoring material (flavoring) may include menthol, spearmint, and / or peppermint. In some embodiments, the flavoring includes cucumber, blueberry, citrus, and / or red berry flavorings. In some embodiments, the flavoring includes eugenol. In some embodiments, the flavoring includes flavorings extracted from tobacco. In some embodiments, the flavoring may include sensates intended to achieve the sensations typically perceived by chemically induced stimulation of the fifth cranial nerve (trigeminal nerve) in addition to or instead of olfactory or gustatory nerves, including agents that produce heating, cooling, tingling, and numbing effects. Suitable thermal effect agents may include, but are not limited to, vanillyl ethyl ether. Suitable cooling agents may include, but are not limited to, eucalyptol and WS-3.

[0024] The carrier material may include one or more materials capable of forming an aerosol, and in some embodiments, the carrier material may include one or more of glycerin, glycerol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 1,3-butylene glycol, erythritol, meso-erythritol, ethyl vanillate, ethyl laurate, diethyl suberate, triethyl citrate, triacetin, diacetin mixtures, benzyl benzoate, benzyl phenylacetate, tributyrin, lauryl acetate, lauric acid, myristic acid, and propylene carbonate.

[0025] The one or more other functional constituents may include one or more of a pH adjuster, a colorant, a preservative, a binder, a filler, a stabilizer, and / or an antioxidant.

[0026] As noted above, aerosol delivery systems (e-cigarettes) often include modular assemblies that include both a reusable portion (body / device) and a replaceable consumable (cartridge) portion. Devices that conform to this type of two-part modular configuration are sometimes generally referred to as two-part devices. Electronic cigarettes also generally have a generally elongated shape. To provide a concrete example, certain embodiments of the present disclosure described herein include generally elongated two-part devices employing this type of consumable component. However, it should be understood that the underlying principles described herein may equally be employed in other e-cigarette configurations (e.g., modular devices including three or more parts), such as devices conforming to other overall shapes based on so-called BOX-MOD high-performance devices, which typically have a more box-like shape.

[0027] 1A-1C, according to some embodiments described herein, there is provided an aerosol delivery system 1 comprising a cartridge 10 and a main body 100. The main body may include a recess / receptacle 102 for releasably receiving, potentially by friction fit, at least one surface 12 of the cartridge 10, wherein the at least one surface 12 of the cartridge 10 is free of any fluid inlet for delivering fluid to the cartridge 10. In this manner, the absence of any fluid inlet for delivering fluid to the at least one surface 12 of the cartridge 10 helps to prevent fluid from leaking from the cartridge 10 into the main body 100 when the cartridge 10 is received in the main body 100 (e.g., when in the position of FIG. 1B, with reference to the embodiment shown in FIGS. 1A-1C).

[0028] According to some of the above embodiments, cartridge 10 may include a first end surface 14 configured to be releasably received in recess 102 and a second end surface 16 opposite first end surface 14 and configured to be outside recess 102 when first end surface 14 is releasably received in recess 102. And, in some of the above embodiments, at least one surface 12 may include first end surface 14 (e.g., as shown in the embodiment of FIGS. 1A-1C in which first end surface 14 does not have any fluid inlets for introducing fluid into cartridge 10).

[0029] To further enhance the safety of cartridge 10 when used with main body 100, cartridge 10 may include multiple side surfaces 18 extending between first end surface 14 and second end surface 16, with at least one surface 12 including first portions 18A of the multiple side surfaces 18. In this regard, including at least one surface 12 including first portions 18A of the multiple side surfaces 18 helps accommodate more of cartridge 10 within the main body when in use. Accordingly, in this regard as well, first portions 18A of the multiple side surfaces 18 do not include any fluid inlets for introducing fluid into cartridge 10, which helps prevent fluid from leaking from cartridge 10 into main body 100 (e.g., as shown in the embodiment of FIGS. 1A-1C in which first portions 18A of the multiple side surfaces 18 do not include any fluid inlets for introducing fluid into cartridge 10).

[0030] When multiple side surfaces 18 are present, according to some embodiments described above, such as the embodiment shown in FIGS. 1A-1C , the multiple side surfaces 18 may include a second portion 18B configured to be outside the recess 102 when the first end surface 14 is releasably received in the recess 102. Such a second portion 18B is best illustrated with reference to the embodiment shown in FIG. 1C . Such a second portion 18B may, in some embodiments described above, include at least one air inlet 20 (or two or more air inlets) for directing air into the cartridge 10. As described below, each such air inlet is configured to allow air to pass through the cartridge 10 and capture a vapor of aerosolizable material that is ultimately inhaled by a user of the cartridge. In embodiments employing multiple air inlets, according to some embodiments described above, such as the embodiment shown in FIG. 1C , the multiple air inlets 20 may include a pair of air inlets located on opposing sides of the multiple side surfaces 18.

[0031] Continuing with reference to cartridge 10, in some embodiments, the cartridge may include a mouthpiece 22 to allow a user to better inhale the vapor produced from cartridge 10. The mouthpiece may include a portion of second portion 18B, and may also include second end surface 16 of the cartridge, as shown in the cartridge embodiment of FIGS. 1A-1C. In some embodiments employing a mouthpiece 22, any air inlet(s) provided in cartridge 10 may be located between mouthpiece 22 and first end surface 14. In some particular embodiments described above, each air inlet may be located adjacent to mouthpiece 22, as shown in the cartridge embodiment of FIG. 1C.

[0032] 1C , according to some embodiments of the aerosol delivery system 1 described herein, the body 100 may include a shroud 104 defining a recess 102, with an end 106 of the shroud 104 including at least one recess 108, each recess 108 configured to align with an air inlet 20 of the cartridge 10 when at least one surface 12 of the cartridge 10 is releasably received in the recess 102. In this manner, the recess 108 may better protect the periphery of the air inlet 20 from accidental damage that could affect the performance of the aerosol delivery system 1 during use of the cartridge 10. In certain embodiments employing a mouthpiece 22, the mouthpiece 22 may be configured to abut the at least one recess 108 when the at least one surface 12 of the cartridge 10 is releasably received in the recess 102. In certain such embodiments, positioning the air inlets 20 in this manner relative to the mouthpiece 22 and the at least one recess 108 more ensures a favorable fit relative to the at least one recess 108, positioning the air inlets 20 outside the recess 102 and better protecting the periphery of each air inlet 20 from accidental damage during use of the cartridge 10. Also advantageously, by positioning the air inlets 20 in this location, a user is less likely to grip the body 100 in an area near the mouthpiece 22, making it less likely that a user will accidentally cover the air inlets 20 with their hands while holding the body. Thus, positioning each air inlet 20 in this location also more ensures that the air inlets 22 will not be blocked and will operate satisfactorily during use of the aerosol delivery system 1.

[0033] Therefore, in light of the above, some embodiments described herein may provide an aerosol delivery system 1 including a cartridge 10 including a mouthpiece 22 and a body including a recess for releasably receiving at least one surface 12 of the cartridge 10, wherein the body includes a shroud 104 defining the recess 102, an end 106 of the shroud 104 including at least one recess 108, each recess 108 configured to align with an 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. And, in some of the above embodiments, the mouthpiece 22 may be configured to be adjacent to the at least one recess 108 when the at least one surface 12 of the cartridge 10 is releasably received in the recess 102.

[0034] To the extent a mouthpiece may be employed, it will be appreciated that this may advantageously facilitate engagement with a recess when cartridge 10 is engaged with body 100. Similarly in this regard, it will be appreciated that the cartridge and corresponding recess / receptacle may employ a non-circular and / or elongated cross-section to facilitate alignment of the cartridge with the recess / receptacle. Such shapes also tend to provide a mouthpiece shape, potentially with the use of beveled sides, that is particularly well-configured to allow a user's lips to more effectively close around any orifice at the end of the mouthpiece through which the user's lips can wrap to deliver vaporized aerosolizable material into the user's mouth.

[0035] It should also be appreciated that, in at least some embodiments, the exterior surface of the mouthpiece (such as the beveled sides of the mouthpiece) may be opaque according to some embodiments. This may prevent a user from seeing the contents of the cartridge during use (as shown in the embodiments of the drawings), such as any plume of vapor that may form inside the cartridge 100, which may be unsettling to some potential users. Similarly in this regard, according to some embodiments as shown in the drawings, the mouthpiece and / or beveled sides may be black and / or matte, so that any marks on the mouthpiece (such as lipstick or any other stains) may be more easily removed and / or less noticeable.

[0036] Thus, from the above, it can be seen that another aspect of the present disclosure relates to a particularly effective shape for the mouthpiece described herein, which, of course, can be used with any type of aerosolizable material, such as solid aerosolizable material (e.g., potentially including tobacco) and / or liquid aerosolizable material (in this latter case, potentially using any of the aerosolizable transfer elements 34 described herein).

[0037] Similarly, in light of the above, according to some embodiments described in this specification, a cartridge 10 for use in an aerosol delivery system 1 may be provided, which has a first end face 14 that does not have any fluid inlets for delivering fluid to the cartridge 10, a second end face 16 opposite the first end face 14, a plurality of side faces 18 extending between the first end face 14 and the second end face 16 and having at least one air inlet 20 for delivering air to the cartridge, and a mouthpiece 22, each air inlet 20 being positioned adjacent to the mouthpiece 22 and between the mouthpiece 22 and the first end face 14.

[0038] In accordance with at least some of the above embodiments, at least one surface 12 of cartridge 10 may be free of a fluid inlet for delivering fluid to cartridge 10, which helps prevent aerosolizable material from leaking from cartridge 10 into the body. In this case, in such embodiments, the fluid inlet may include an air inlet 20 to prevent residual moisture in air passing therethrough from reaching body 100, and / or an inlet for aerosolizable material (to prevent vaporized aerosolizable material from reaching body 100).

[0039] Thus, the above embodiments describe embodiments that are more conducive to preventing aerosolizable material from leaking from cartridge 10 into body 100.

[0040] Turning to other aspects of the aerosol delivery system 1 described herein, according to some embodiments described above, the cartridge may be provided with a first reservoir 30 for containing the aerosolizable material, and the aerosol delivery system 1 may, in some embodiments, further be provided with a vaporizer 32 for vaporizing the aerosolizable material from the first reservoir 30. In some embodiments described above, generally, air may then pass through the air inlet 20 and through the vaporizer 32 to form a vapor of the aerosolizable material, which ultimately exits the mouthpiece 22 and is inhaled by a user when the aerosol delivery system 1 is in use, as described below.

[0041] According to some more specific embodiments, such as those shown in Figures 2A-3D, the cartridge 10 may include an aerosolizable material transfer element 34 for receiving the aerosolizable material from the first reservoir 30, and the vaporizer 32 is configured to vaporize the aerosolizable material in the aerosolizable material transfer element 34.

[0042] To add flavoring material to any vapor delivered to the user, some embodiments of the cartridge may further include a second reservoir 36 for containing the flavoring material. If such a second reservoir 36 is employed, it may be located upstream of any provided vaporizer 32 (to deliver the flavoring material prior to vaporization of the aerosolizable material) and, according to some embodiments, may be configured to add the flavoring material from the first reservoir 30 to the aerosolizable material prior to vaporization by the vaporizer 32. However, in other embodiments, such as those shown in FIGS. 2A-3D , the second reservoir 36 may be configured to receive vaporized aerosolizable material from the vaporizer 32. With regard to the spatial location of any provided second reservoir 36 relative to the first reservoir 30, it will be appreciated that the second reservoir 36 may be located in many different locations within the cartridge. However, according to some embodiments, the first reservoir 30 may be located between the second reservoir 36 and the first end face 14 to facilitate a compact configuration of the cartridge 10. Similarly and / or alternatively, in some embodiments, the second reservoir 36 may be enclosed within the mouthpiece 22 (if employed) and / or configured to deliver vaporized flavored aerosolizable material through an outlet 37 of the cartridge 10 / aerosol delivery system 1. Such outlet 37 may, in some particular embodiments, be located at the second end face or in a recess / orifice 39 extending from the second end face 16 (as in the embodiment shown in Figures 2A-3D). For the avoidance of doubt, it should be understood that any provided outlet 37 may be located in a variety of different locations on the cartridge 10, depending on the exact shape / configuration of the cartridge 10 employed.

[0043] Similarly, if a second reservoir 36 is employed, it will further be appreciated that the second reservoir 36 may include any combination of flavoring material(s), such as any of the flavoring materials described above, although according to some particular embodiments, the flavoring material may include tobacco and / or nicotine.

[0044] Moving from the optional second reservoir 36 provided to how air / vapor may be guided through the cartridge 10 during use, according to some embodiments as shown in FIGS. 2A-3D , the cartridge 10 may include a first channel 38 for receiving air from the air inlet(s) 20 of the cartridge 10. The cartridge 10 may then include a second channel 40 disposed downstream from the first channel 38 and configured to receive vaporized aerosolizable material from the vaporizer 32 (described below). In some embodiments described above, the first channel 38 may be parallel to the second channel 40, or may be disposed outside the second channel 40, to facilitate a compact configuration of the cartridge 10. Similarly and / or alternatively, in some embodiments, the first channel 38 may be disposed closer to the sides 18 than the second channel 40.

[0045] For embodiments in which any first channel 38 is parallel to a second channel 40, these and potentially other embodiments may be configured to have air flow along the first channel 38 in a first direction A1, and to have vaporized aerosolizable material from the vaporizer 32 flow along the second channel 40 in a second direction A2, the second direction A2 being opposite the first direction A1. For example, the cartridge embodiment shown in FIGS. 3A-3C illustrates these first and second directions A1 and A2. In such embodiments, the change in direction from first direction A1 to second direction A2 may increase the turbidity of the air passing over the vaporizer 32 and / or any provided aerosolizable material transfer element 34 (each / both of which may be located at the (downstream) end 38A of the first channel 38 and the (upstream) end 40A of the second channel 40). This increased turbidity may be more likely to form and pass vapor along second direction A2 into second channel 40.

[0046] Continuing with the shape of second channel 40, according to some space-efficient embodiments, second channel 40 may be disposed between first end surface 14 and any provided second reservoir 36. Similarly / alternatively, second channel end 40A may be disposed adjacent to any aerosolizable material transfer element 34 provided in cartridge 10.

[0047] Turning to the features of any vaporizer 32 and / or aerosolizable material transfer element 34 provided, the purpose of these features is to vaporize aerosolizable material from first reservoir 30 to produce vaporized aerosolizable material that can be provided to a user during use of aerosol delivery system 1. In this regard, any vaporized aerosolizable material may pass along second channel 40, through the second reservoir, and out outlet 37.

[0048] In theory, the vaporizer 32 may take a variety of different forms, such that it can be configured to generate vapor / aerosol from the aerosolizable material by applying heat (e.g., by a heater / heating element) or without applying heat (e.g., by one or more of the vibrational, mechanical, pressurized, or electrostatic means described above).

[0049] Meanwhile, according to some embodiments, the vaporizer 32 may include a heating element 32A disposed in the body 100, or may be configured to be at least partially disposed in the body 100 and at least partially disposed in the cartridge 10, as shown in the embodiment of the drawings, for example. And, according to some particular embodiments described above, the cartridge 10 may include a heat transfer surface 32B (which may be an external heat transfer surface) for receiving heat from the heating element 32A disposed in the body 100, and this heat transfer surface 32B forms part of the vaporizer 32.

[0050] Thus, according to the particular embodiment described above and shown in the drawings, the vaporizer 32 may be formed in two parts: a first portion 32A of a heating element disposed on the body 100, and a second portion in the form of a heat transfer surface 32B disposed on the cartridge 10. As such, the heat transfer surface 32B is configured to contact the heating element 32A when the at least one surface 12 of the cartridge 10 is releasably received in the recess 102 of the body 100. The provision of this two-part vaporizer 32 provides a number of advantages, particularly with respect to eliminating a fluid inlet from the at least one surface 12 of the cartridge 10, which may help prevent leakage of aerosolizable material from the cartridge 10 into the body 100. Furthermore, the division of the vaporizer 32 between the cartridge 10 and the body 100 adds a safety feature that prevents operation of the vaporizer 32 when the cartridge 10 is separated from the body 100. It is also helpful to note that by locating a portion of the vaporizer 32 in the body 100, the number of components in the cartridge 10 can be reduced and in some embodiments the cartridge can be configured as a consumable / disposable item.

[0051] With the above in mind, when an (external) heat transfer surface 32B is employed, according to some of the above-described embodiments, this heat transfer surface 32B may comprise part of a conductive member 46 (which, in some particular embodiments, may comprise a conductive plate or foil) of the cartridge 10, with the aerosolizable material transfer element 34 contacting the conductive member 46. In this manner, when the heating element 32A contacts the heat transfer surface 32B, heat from the heating element 32A is transferred through the heat transfer surface 32B and the conductive member 46 to the aerosolizable material transfer element 34. Such an embodiment is illustrated in FIG. 1C . In other words, according to some of the above-described embodiments, and theoretically other embodiments, the aerosolizable material transfer element 34 may contact the conductive member 46 at a contact surface 48 of the conductive member 46, with the contact surface 48 being opposite and / or parallel to the (external) heat transfer surface 32B. In some embodiments, such as those shown in the figures, at least one of contact surface 48 and the corresponding surface of aerosolizable material transfer element 34 that contacts contact surface 48 may be flat.

[0052] As briefly mentioned above, the exact shape of any provided conductive member 46 may vary depending on the application in any provided aerosol delivery system 1. However, according to certain embodiments, the conductive member 46 may comprise a conductive plate or foil and may be constructed of a heat-conductive material such as, but not limited to, a metal. Similarly, when a conductive member 46 is employed, according to certain embodiments, the conductive member 46 may define the first end surface 14 of the cartridge 10, similar to the embodiment of the cartridge 10 shown in the drawings. Purely for the sake of completeness, it is contemplated that the conductive member 46 may be attached to the cartridge 10 and / or the aerosolizable material transfer element 34. In this regard, for example, according to certain embodiments, 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 transfer element 34 by at least one of a crimping action, an adhesive, or a mechanical fastening means.

[0053] As noted above, according to some embodiments, the conductive member 46 may comprise a conductive plate or foil. In this manner, the conductive member 46 may be particularly thin, which may help ensure efficient heat transfer throughout the conductive member 46. In this regard, according to some particular embodiments, the thickness of any such conductive member 46 may be 5 mm or less. In other additional / alternative embodiments, the thickness of any such conductive member 46 may be between 0.5 mm and 5 mm, or between 1 mm and 5 mm, as the best balance between providing a conductive member 46 that is particularly efficient at transferring heat throughout its thickness while also having a sufficient thickness to withstand any accidental punctures.

[0054] Regarding the exact placement of the heat transfer surface 32B (and / or conductive member 46), in a particularly compact and space-efficient embodiment, the second channel 40 may be located between any provided second reservoir 36 and the heat transfer surface 32B (conductive member 46).

[0055] The foregoing describes specific embodiments of an aerosol delivery system employing a vaporizer 32 split between a cartridge 10 and a body 100. However, according to some more general embodiments, the above disclosure can provide a cartridge 10 for use in an aerosol delivery system 1 comprising a cartridge 10 and a body 100, the cartridge 10 comprising an external heat transfer surface 32B for receiving heat from a heating element 32A located in the body 100.

[0056] Similarly, in a general sense, the above disclosure can provide an aerosol delivery system 1 comprising a cartridge 10 and a main body 100, wherein the cartridge 10 has an external heat transfer surface 32B for receiving heat from a heating element 32A disposed in the main body 100.

[0057] Apart from the vaporizer 32, according to some embodiments, the aerosol delivery system 1 described herein may be provided with an aerosolizable material transfer element 34 for receiving aerosolizable material (such as aerosolizable material from the first reservoir 30).

[0058] In general, the structure and composition of aerosolizable material transfer element 34 (also referred to as a wick) can be any suitable structure and composition so long as it adequately draws aerosolizable material to a location where it can be vaporized by vaporizer 32 during use of the aerosol delivery system. Thus, according to some embodiments, aerosolizable material transfer element 34 can include porous, fibrous, and / or solid materials. In some embodiments, aerosolizable material transfer element 34 can be constructed of cotton or ceramic. With this in mind, it should be understood that, at a general level, the specific structure and composition of the aerosolizable material transfer element can be varied to best accommodate any intended use of aerosol delivery system 1.

[0059] Thus, according to some embodiments described herein, an aerosolizable material transfer element 34 may be provided having a particular shape, such as, but not limited to, the shape shown in the embodiment of cartridge 10 of the drawings. Specifically, therefore, as described below, an aerosolizable material transfer element 34 for use in aerosol delivery cartridge 10 or aerosol delivery system 1 may be provided, having a length L extending between a first end 50 of the aerosolizable material transfer element 34 and a second end 52 of the aerosolizable material transfer element 34. In some of the above embodiments, the cross-sectional area A of the aerosolizable material transfer element 34 (orthogonal to length L) may be configured to vary along the length L of the aerosolizable material transfer element 34. For example, referring to the embodiment of FIG. 2D in which such an aerosolizable material transfer element 34 is employed, such an embodiment of an aerosolizable material transfer element 34 is best illustrated.

[0060] For such an aerosolizable material transfer element 34, if the cross-sectional area A of the aerosolizable material transfer element 34 varies along the length L of the aerosolizable material transfer element 34, the aerosolizable material transfer element 34 can more efficiently guide the aerosolizable material from a location adjacent the first reservoir 30 to a location closer to the vaporizer 32 where the aerosolizable material can be vaporized. For the sake of completeness, with respect to the cross-sectional area A, if the aerosolizable material transfer element 34 is divided into multiple cross-sectional areas at a given location along the length L of the aerosolizable material transfer element 34, the cross-sectional area A at that axial location along the length L will be interpreted as the sum of the multiple cross-sectional areas at that axial location (e.g., the sum of the cross-sectional area A′ and the cross-sectional area A″ as shown in the embodiment of FIG. 3B for an aerosolizable material transfer element 34 divided into two at an axial location along the length L of the aerosolizable material transfer element 34).

[0061] In light of the above, in accordance with certain embodiments above and other embodiments of the aerosolizable material transfer element 34 described herein, any aerosolizable material transfer element provided may include a first leg 54 extending from a first end 50, a second leg 56 extending from a second end 52, and a central body portion 58 disposed between the first leg 54 and the second leg 56. In certain embodiments above, the central body portion may include an opening 60 extending through the thickness of the aerosolizable material transfer element 34. The primary function of the opening 60 is to increase the exposed surface area of ​​the aerosolizable material transfer element 34, thereby increasing the amount of vaporized aerosolizable material that may be produced from the aerosolizable material transfer element 34. Thus, for a given size of aerosolizable material transfer element 34, this increased surface area may be advantageous in that it allows for the use of a smaller aerosolizable material transfer element 34 than would otherwise be possible. A second function of the openings is to allow more heat from vaporizer 32 (such as external heat transfer surface 32B) to reach second channel 40 and the vicinity of aerosolizable material transfer element 34, thereby ensuring more reliable heating of the aerosolizable material. According to such an embodiment, the introduction of openings 60 advantageously facilitates better guiding of vaporized aerosolizable material from aerosolizable material transfer element 34 into and along second channel 40 toward outlet 37. This guiding effect can be seen with reference to the wavy arrows shown in FIGS. 3B and 3C , which are positioned near openings 60 and extend toward second channel 40. In a specific embodiment in which the above effect is additionally demonstrated, any openings 60 provided may penetrate the thickness of aerosolizable material transfer element 34 perpendicular or orthogonal to length L of aerosolizable material transfer element 34 and / or parallel to first direction A1 and / or parallel to second direction A2.

[0062] According to some embodiments, the openings 60 may be cylindrical and / or may include a uniform cross-section through the thickness of the aerosolizable material transfer element 34 to facilitate more consistent formation of vaporized aerosolizable material around any openings 60 provided, according to some particular embodiments.

[0063] According to some embodiments, such as the embodiment shown in the drawings, the conductive member 46 (if employed) may cover the end of the opening 60, thereby allowing any heat from the conductive member 46 to be directed upward through the opening 60, ensuring better relay into and around the aerosolizable material transport element 34 and into the second channel 40.

[0064] Apart from any openings 60 provided in the aerosolizable material transfer element 34, according to some embodiments, each leg 54, 56 of the aerosolizable material transfer element 34 may be configured to be in fluid communication with the first reservoir 30 to receive aerosolizable material therefrom. Such an embodiment is shown in FIG. 3C. Thus, in such an embodiment, passage of aerosolizable material from the first reservoir 30 from each leg 54, 56 to the central body portion 58 of the aerosolizable material transfer element 34 may be effectively facilitated.

[0065] In addition to the above, according to some additional / alternative embodiments, the first channel 38 may include at least one orifice 64 in fluid communication with the second channel 40, each orifice 64 adjacent to the aerosolizable material transfer element 34 and / or, more specifically, the central body portion 58 of the aerosolizable material transfer element (if a central body portion 58 is employed). In this manner, air passing through the orifice 64 from the first channel may directly impinge on the aerosolizable material transfer element, maximizing the magnitude of vapor that is pumped into the air and subsequently into the second channel 40.

[0066] Similarly, to better position the aerosolizable material transfer element 34 adjacent each orifice 64 (and thus better prevent lateral movement of the aerosolizable material transfer element 34 during use), as well as to aid in vaporization of the aerosolizable material from the aerosolizable material transfer element 34, according to some embodiments, the aerosolizable material transfer element 34 (or, in some particular embodiments, its central body portion 58) may include, for each orifice 64, a recess 66 located adjacent the orifice 64, as shown, for example, in the embodiment of FIG. 3B . In this regard, it has been found that by forming a narrowed portion in the aerosolizable material transfer element 34 in which it is located, the efficiency of vaporization of the aerosolizable material from the aerosolizable material transfer element 34 is surprisingly increased. Similarly, the increased exposed surface area of ​​the aerosolizable material transfer element 34 created by each recess 66 can aid in increasing the amount of vaporized aerosolizable material that can be produced from the aerosolizable material transfer element 34. Thus, for a given size of aerosolizable material transfer element 34, increasing the surface area in this manner (such as by providing optional openings 60, if present) can be effective in allowing a smaller size of aerosolizable material transfer element 34 to be used than would otherwise be possible.

[0067] In embodiments employing more recesses 66 (orifices 64), according to certain embodiments described above, a first recess 66 disposed on a first side of the aerosolizable material transfer element 34 and a second recess 66 disposed on a second side of the aerosolizable material transfer element 34 may be provided, with the first side being opposite the second side, as shown in the embodiment of FIG. 3B. According to certain embodiments, again as shown in the embodiment of FIG. 3B, the first and second sides of the aerosolizable material transfer element 34 may be the first and second sides of the central body portion 58. In other words, according to certain embodiments, the first and second sides of the aerosolizable material transfer element 34 may be disposed adjacent to the first and second orifices 64, respectively, of the at least one orifice 64.

[0068] Continuing with the orifice(s) 64, according to some embodiments, each orifice 64 may extend in a direction A4 perpendicular to the first direction A1 and the second direction A2 between the first channel 38 and the second channel 40. This change in direction may aid in better vapor formation and passage through the second channel 40 along the second direction A2 by increasing the turbidity of the air passing over the vaporizer 32 and / or any aerosolizable material transfer element 34. Similarly, according to some embodiments, each orifice 64 may extend in a direction A4 perpendicular to the length L of the aerosolizable material transfer element. In this manner, the air and aerosolizable material can be more efficiently spaced and controlled within the cartridge 10, theoretically additionally enabling a narrower / narrower aerosolizable material transfer element 34, as shown in the embodiment of the cartridge 10 in the drawings.

[0069] In light of the above, it will therefore be appreciated that the above-described embodiments allow for the inventive design of aerosolizable material transfer elements 34, all of which are effective and well suited for use in aerosol delivery cartridge 10 and / or aerosol delivery system 1. Indeed, purely for the avoidance of doubt, it is believed that if any of the above-described aerosolizable material transfer elements 34 are employed, it may be employed in any of the cartridges 10 or aerosol delivery systems 1 described herein.

The aerosol delivery system 1 also includes a conductive member 46 in the form of a conductive plate or foil that contacts the aerosolizable material transfer element 34 and includes a heat transfer surface 32B for receiving heat transferred to the aerosolizable material transfer element 34.

[0087] Also described is an aerosol delivery system 1 for forming a vapor from an aerosolizable material, the aerosol delivery system 1 comprising a cartridge 10 containing the aerosolizable material to be vaporized and a body 100 for releasably housing the cartridge.

The advantages and features of the present disclosure are merely a representative sample of embodiments and are not intended to be exhaustive and / or exclusive.

[0097] With respect to the vaporizer 32, as previously discussed, the vaporizers 32 described herein may take a variety of different forms. In this regard, while the vaporizers 32 described herein are primarily described as being at least partially disposed in the body and at least partially disposed in the cartridge, it is contemplated that, according to some embodiments, any vaporizer provided may be disposed solely in the cartridge 10 or solely in the body 100. Similarly, while the vaporizers 32 described herein are, in some embodiments, described as including a heater / heating element, it will be appreciated that in other embodiments, the vaporizer may be capable of generating a vapor / aerosol from an aerosolizable material without the application of heat, for example, by one or more of vibrational, mechanical, pressurized, or electrostatic means as discussed above.
