Description

[Technical field]

[0001] The present invention relates to an aerosolizable material, an aerosol delivery system, a method of delivering an aerosol, and a method of producing an aerosolizable material. [Background technology]

[0002] Aerosol delivery systems are well known. Typical systems use a heater to generate an aerosol from an aerosolizable material, which is then inhaled by the user. The aerosolizable material from which the aerosol is generated may be partially or completely consumed during use of the aerosol delivery system. Heating the aerosol-generating material may cause it to change structurally. Over time, the structural changes may reduce the user's palatability of the aerosol delivery system by changing flavors or by making the aerosol-generating material more difficult to use as it is consumed. The temperature used to generate the aerosol from the aerosol-generating material may change throughout use as these structural changes occur.

[0003] It would be desirable to have an aerosol delivery system that effectively and efficiently heats the aerosol-forming material.

[0004] The present invention is directed to solving some of the problems mentioned above. Summary of the Invention

[0017] While the invention is susceptible to various modifications and alternative forms, specific embodiments have been shown by way of example in the drawings and are herein described in detail. It should be understood, however, that the drawings and detailed description of the specific embodiments are not intended to limit the invention to the specific forms disclosed. On the contrary, the invention covers all modifications, equivalents, and alternatives included within the scope of the invention as defined by the appended claims.

[0018] Aspects and features of some examples and embodiments are discussed / described herein. Some aspects and features of some examples and embodiments may be conventionally implemented, and for the sake of brevity, such aspects and features will not be discussed / described in detail. Thus, it should be understood that aspects and features of the apparatus and methods discussed herein but not described in detail may be implemented according to any conventional technique for implementing such aspects and features.

[0019] The present disclosure relates to an aerosol delivery system, which may also be referred to as an aerosol delivery system, such as an e-cigarette. According to the present disclosure, a "non-combustible" aerosol delivery system is one in which the aerosol delivery system's aerosolizable compositional material (or components of the aerosol delivery system) is not burned or charred to facilitate delivery to a user. Throughout the following description, the term "e-cigarette" or "electronic cigarette" may be used, but it should be understood that the term can be used interchangeably with aerosol delivery system / device and electronic aerosol delivery system / device. Additionally, as is common in the art, the terms "aerosol" and "vapor" and related terms such as "evaporate", "volatilize" and "aerosolize" can generally be used interchangeably.

[0020] In the example of FIG. 1, an aerosolizable material 100 is shown for use in an aerosol delivery system. The aerosolizable material 100 can be inserted into or coupled to an aerosol delivery system. The aerosol delivery system can generate an aerosol from the aerosolizable material 100. The aerosolizable material 100 includes at least one active composition 110. The aerosolizable material 100 includes at least one thermally conductive element 120. The at least one thermally conductive element 120 has a thermal conductivity of about 10 W / mK to about 500 W / mK. In the example shown in FIG. 1, the aerosolizable material 100 may include other components.

[0021] The at least one active composition 110 may include one or more flavorings, one or more aerosol-forming materials, and / or one or more functional materials. In certain examples, the at least one active composition 110 may include nicotine or a nicotine-containing substance.

[0022] The at least one thermally conductive element 120 aids in the effective transfer of thermal energy within the aerosolizable material 100. The at least one thermally conductive element 120 shown in the particular example of FIG. 1 is separate from the at least one active composition 110. In one example, the at least one active composition 110 and the at least one thermally conductive element 120 may be mixed, in contact, or partially intermingled. The placement of the at least one thermally conductive element 120 within the aerosolizable material 100 may be selected to allow efficient heat transfer from one portion of the aerosolizable material 100 to another portion. The placement may be selected or the aerosolizable material may be designed by knowing the areas of low thermal conductivity within the aerosolizable material 100.

[0023] In another example, the placement of the at least one thermally conductive element 120 within the aerosolizable material 100 can be selected by understanding the unique heat flow paths within the aerosol delivery system and the manner in which these heat flow paths interact with the aerosolizable material 100. For example, if heat is delivered to the aerosolizable material 100 primarily from one side of the aerosolizable material 100, the at least one thermally conductive element 120 can be positioned to effectively conduct heat to the other side of the aerosolizable material 100.

[0024] In one example, at least one thermally conductive element 120 includes a binder. A binder can be a material or substance that holds or attracts other materials together to form a bond mechanically, chemically, by adhesion or bonding. The use of a binder aids in the formation of the structure of the aerosolizable material 100. Preserving the structure of the aerosolizable material 100 helps prevent structural degradation that may occur during heating of the aerosolizable material 100. Such structural degradation may result in uneven heating of the aerosolizable material 100, which may lead to the formation of undesirable compounds by overheating some parts of the aerosolizable material 100. Specific thermally conductive binders that may be advantageous include methylcellulose, carboxymethylcellulose, alginates, and gels. The binder only needs to have a thermal conductivity greater than that of the aerosolizable material (that of tobacco) to improve heat transfer within the aerosolizable material. Thus, some binders may be used with aerosolizable materials of lower thermal conductivity, but may not be compatible with aerosolizable materials of higher thermal conductivity.

[0025] In the example of Figure 2, an aerosolizable material 200 is shown. The aerosolizable material 200 has at least one active composition 210 and at least one thermally conductive element 220. The at least one thermally conductive element 220 is shown to include a binder 222. In the schematic example of Figure 2, the binder 222 is shown as being confined within the at least one thermally conductive element 220. The binder 222 can be distributed uniformly or non-uniformly throughout the at least one thermally conductive element 220. The thermally conductive element 220 and / or the binder 222 can be distributed uniformly or non-uniformly throughout the aerosolizable material 200. The binder 222 can aid in improving heat transfer throughout the aerosolizable material 200.

[0026] In one example, the at least one thermally conductive element 220 comprises up to 20% of the volume of the aerosolizable material 200. In other examples, the at least one thermally conductive element 220 comprises up to 1%, up to 2%, up to 3%, up to 4%, up to 5%, up to 6%, up to 7%, up to 8%, up to 9%, up to 10%, up to 11%, up to 12%, up to 13%, up to 14%, up to 15%, up to 16%, up to 17%, up to 18%, or up to 19% of the volume of the aerosolizable material 200. The amount of thermally conductive element 220 can be selected to balance the active composition 210 present in the aerosolizable material 200 to produce flavors, etc. during use, and the contribution to thermal conductivity provided by the thermally conductive element 220. In examples where the thermal conductivity of the active composition 210 is significantly low, this can be overcome by using a larger amount of the thermally conductive element 220. In instances where the active composition 210 has better thermal conductivity, the amount of thermally conductive elements 220 within the aerosolizable material 200 can be less.

[0027] In the example of FIG. 3, an aerosolizable material 300 is shown. The aerosolizable material 300 includes at least one active composition 310 and at least one thermally conductive element 320. In the example of FIG. 3, the at least one thermally conductive element 320 is located substantially away from the outer surface 302 of the aerosolizable material 300. The location of the at least one thermally conductive element 320 can be selected to allow the transfer of thermal energy to a portion of the aerosolizable material 300 that is less prone to receiving thermal energy during use. In another example, not shown, the at least one thermally conductive element is located substantially near the outer surface of the aerosolizable material. This can bias heat from an external source toward the center of the aerosolizable material. For example, if a passing aerosol is the heating means, an advantageous location would be on the outside of the aerosolizable material, as the aerosol can pass through a homogenous mixture of the aerosolizable material.

[0028] As used herein, "locating" and "disposing" the thermally conductive element 320 may also be seen to refer to a distribution of density of the at least one thermally conductive element 320 within the aerosolizable material 300. In one example, rather than disposing the at least one thermally conductive element 320 away from the outer surface 302 of the aerosolizable material 300, the thermally conductive element 320 may be denser at a central location of the aerosolizable material 300. The density profile may vary from portions of the aerosolizable material 300 that receive more thermal energy (lower density) to portions that receive less thermal energy (higher density).

[0029] Thus, in one example, the thermally conductive elements 320 may be concentrated in certain portions of the aerosolizable material 300 and are not uniformly distributed. The thermally conductive elements 320 may be disposed in clumps (as in FIG. 3) in certain locations within the aerosolizable material 300 rather than as discrete individual elements. Thus, in such an example, a thermal or physical network may be provided by the thermally conductive elements 320. Such a network may be continuous or discontinuous and may be formed such that one or more portions of the thermally conductive elements 320 are in contact within the network.

[0030] This is advantageous because it allows a manufacturer to achieve a customized temperature profile that can be formed during heating of the aerosolizable material 300, which may or may not be uniform throughout the aerosolizable material 300. The advantage of a non-uniform heat distribution is that it allows a manufacturer to engineer additional heating in locations of the aerosolizable material 300 that require heating, such as portions closer to the center of the aerosolizable material 300 that cannot be heated as easily as the outwardly facing surfaces.

[0031] The center of the aerosolizable material 300 may receive less thermal energy (from an external heating source) than portions located closer to the exterior surface 302. Thus, in one example, the thermally conductive element 320 may be configured to effectively transfer thermal energy to the center of the aerosolizable material 300. This may be by selection of a density profile or rod-like structure that the thermally conductive element 320 may be configured or arranged in. Such rods may flare from the exterior surface to the center such that the rods are denser toward the center of the aerosolizable material 300.

[0032] The selection of density (or density change) of the thermally conductive elements 320 within the aerosolizable material 300 should avoid concentrations of thermal energy that could cause the active composition 310 to overheat and produce undesirable compounds.

[0033] In one example, the at least one thermally conductive element 320 includes at least one of a metal, an alloy, a ceramic, glycerol, and graphite. The glycerol may be vegetable glycerol.

[0034] In the example of Figure 4, an aerosolizable material 400 is shown. The aerosolizable material 400 includes at least one active composition 410 and at least one thermally conductive element 420. In the example of Figure 4, the at least one thermally conductive element 420 includes at least a first binder material 422 and a second binder material 424. In one example, the first binder material 422 has a thermal conductivity of about 300 to about 400 W / mK and the second binder material 424 has a thermal conductivity of about 10 to about 200 W / mK.

[0035] Providing multiple portions with different thermal conductivities within at least one thermally conductive element 420 can allow for greater flexibility in terms of the thermal conductivity achieved by the thermally conductive element 420 as a whole. This, in turn, improves control over the thermal conductivity achieved by the thermally conductive element 420. In one example, it is advantageous to place a material with a higher thermal conductivity near the outer surface 402 of the aerosolizable material 400 and a material with a lower thermal conductivity near the center, such that during use, heat is conducted toward the center of the aerosolizable material 400, but is more effectively retained once delivered. In the above example, it is assumed that thermal energy is applied to the aerosolizable material 400 such that the outer surface 402 receives at least a majority (if not all) of the incident heat. This, of course, depends on the aerosol delivery device in which the aerosolizable material 400 is used.

[0036] In one example, at least one active composition 410 includes a flavoring. The flavoring can be an olfactory, etc. The active composition 410 can include an active substance. The active substance can be, for example, caffeine, etc.

[0037] As used herein, the active composition 410 may be a physiologically active material, which is a material designed to achieve or enhance a physiological response. The active composition 410 may be selected from, for example, functional foods, nootropics, and psychotropic drugs. The active ingredient 410 may be of natural or synthetic origin. The active composition 410 may include, for example, nicotine, caffeine, taurine, theine, vitamins such as B6 or B12 or C, melatonin, cannabinoids, or compositions, derivatives, or combinations thereof. The active composition 410 may include one or more compositions, derivatives, or extracts of tobacco, cannabis, or another botanical.

[0038] In some embodiments, the active composition 410 includes nicotine. In some embodiments, the active composition includes caffeine, melatonin, or vitamin B12. In some embodiments, the active composition 410 includes tobacco.

[0039] In the example of Fig. 5, an aerosol delivery system 500 is shown. The aerosol delivery system 500 comprises a power source 530. The power source 530 may be a source of chemical energy, such as a battery. The aerosol delivery system 500 comprises an aerosolizable material 505. The aerosol delivery system 500 further comprises a heater 540 that provides heat to the aerosolizable material 505. The aerosolizable material 505 comprises at least one active composition 510 and at least one thermally conductive element 520. The power source 530 is connected to the heater 540. The power source 530 and the heater 540 may be arranged to convert chemical energy into thermal energy. The thermal energy is incident on a surface 507 of the aerosolizable material 505 facing the heater 540.

[0040] When the heater provides thermal energy to the aerosolizable material 505, the active composition 510 can release compounds capable of forming an aerosol into the air passing through the system 500. The aerosol can exit the system 500 via the outlet 509. Over time, the active composition 510 adjacent the surface 507 can be depleted, requiring heat to be applied to new portions of the active composition 510. The placement of the thermally conductive element 520 can allow depletion of the active composition 510 to occur more uniformly throughout use. This helps prevent the active composition 510 from being partially heated as it is depleted, which can result in the release of undesirable compounds.

[0041] In the example of Figure 6, an aerosol delivery system 600 is shown. The aerosol delivery system 600 comprises a power source 630. The power source 630 may be a source of chemical energy, such as a battery. The aerosol delivery system 600 comprises an aerosolizable material 605. The aerosol delivery system 600 further comprises a heater 640 that provides heat to the aerosolizable material 605. The aerosolizable material 605 comprises at least one active composition 610 and at least one thermally conductive element 620. The power source 630 is connected to the heater 640. Thermal energy from the heater 640 is incident on a surface 607 of the aerosolizable material 605 that faces the heater 640.

[0042] The arrangement of the example shown in FIG. 6 differs from that of the example shown in FIG. 5. At least one thermally conductive element 620 is arranged to protrude along a centrally located longitudinal axis of the aerosolizable material 605. At least one active composition 610 is shown on either side of the centrally located at least one thermally conductive element 620. This arrangement allows heat incident on the surface 607 of the aerosolizable material 605 to be conducted by the at least one thermally conductive element 620 to the remaining portion of the aerosolizable material 605. Thus, this arrangement helps to allow the aerosolizable material 605 to be heated more uniformly. As a result, this arrangement of the at least one thermally conductive element 620 helps to prevent the at least one active composition 610 near the surface 607 from being overheated and generating undesirable compounds.

[0043] In one example, the power source 630 provides energy to the heater 640, and the heater 640 is set to operate at approximately 70° C. The use of at least one thermally conductive element 620 allows for efficient heat transfer within the aerosolizable material 605. Thus, the system 600 can operate at a lower temperature. In this manner, the use of at least one thermally conductive element 620 can reduce the load on the power source 630 and the heater 640, increasing the life of the system 600 per charge (because less power source 630 energy is required per puff) and increasing the life of the system 600 overall (because less electrical strain is placed on the elements within the system 600). In one example, the power source 630 and the heater 640 can operate to heat the aerosolizable material 605 to approximately 70° C.

[0044] Any of the disclosed aerosol delivery systems may have control circuitry arranged to control the heating that generates the aerosol, and / or receive signals from a sensor or a user, and / or control the movement of the guidance element (or portions of the guidance element), etc. The control or control circuitry may be connected to a database that determines when certain predefined values ​​exceed or fall outside of predefined ranges. This may result in controlling the heating of a heater, or controlling the flow of aerosol through the aerosol delivery system.

[0045] Heating can be accomplished by a resistive heater that provides thermal energy to the aerosolizable material 605. Thus, in one example, the thermally conductive material can be heated by resistive heating. In one example, the thermally conductive material cannot be heated inductively or magnetically. For example, the thermally conductive material can be formed of at least one ceramic and a binder, and the like.

[0046] In some embodiments, the aerosol delivery system is an e-cigarette, also known as a vaping device or electronic nicotine delivery system (END), although it should be noted that the presence of nicotine within the aerosolizable material is not a requirement.

[0047] In some embodiments, the aerosol delivery system is a tobacco heating system, also known as a non-combustion heating system.

[0048] In some embodiments, the aerosol delivery system is a hybrid system that generates an aerosol using a blend of aerosolizable materials, one or more of which may be heated. Each of the aerosolizable materials may be in the form of, for example, a solid, liquid, or gel, and may or may not contain nicotine. In some embodiments, the hybrid system comprises a liquid or gel aerosolizable material and a solid aerosolizable material. The solid aerosolizable material may include, for example, tobacco or a non-tobacco product.

[0049] Typically, an aerosol delivery system may comprise an aerosol delivery device and an article for use with the aerosol delivery device, although it is recognized that articles that themselves include means for energizing an aerosol generating component may themselves form an aerosol delivery system.

[0050] In some embodiments, the aerosol delivery device can include a power source and a controller. The power source can be, for example, a source of electrical power.

The aerosolizable material may be in the form of a solid, liquid, or gel, which may or may not contain nicotine and / or flavorings. In some embodiments, the aerosolizable material may include an "amorphous solid," which may alternatively be referred to as a "monolithic solid" (i.e., non-fibrous). In some embodiments, the amorphous solid may be a dry gel. An amorphous solid is a solid material that can hold some fluid, such as a liquid, within it.

The active composition may include, for example, nicotine, caffeine, taurine, or any other suitable composition. The active composition may include tobacco or another botanical composition, derivative, or extract. In some embodiments, the active composition is a physiologically active composition and may be selected from nicotine, nicotine salts (e.g., nicotine bitartrate / nicotine bitartrate), nicotine-free tobacco substitutes, and other alkaloids such as caffeine.

[0056] In one embodiment, the active composition is an olfactory active composition and can be selected from "flavors" and / or "flavorings" that can be used to produce a desired flavor, aroma, or other somatosensory sensation in products intended for adult consumers, as permitted by local regulations.
