Description

Technical Field

[0001] This application claims priority and benefit to U.S. Patent Application No. 16 / 861,779, filed Apr. 29, 2020, entitled "Aerosol Delivery Device with Sliding and Transversely Rotating Locking Mechanism", which is hereby incorporated by reference in its entirety.

[0002] The present disclosure relates to aerosol delivery devices and systems, such as smoking articles, and in particular to aerosol delivery devices and systems that utilize a heat source, such as a combustible carbon-based ignition source, to generate an aerosol (e.g., an aerosol for the purpose of obtaining components of tobacco, tobacco extracts, nicotine, synthetic nicotine, non-nicotine flavors, and other materials in an inhalable form generally referred to as non-combustion heating systems or electronic cigarettes). The components of such articles may be manufactured or derived from tobacco, or the articles may otherwise be characterized as incorporating tobacco for human consumption, and may vaporize components of tobacco and / or other tobacco-related materials to form an inhalable aerosol for human consumption.

Background Art

[0003] Over the years, many smoking articles have been proposed as improvements or alternatives to combustion-based tobacco smoking products. Exemplary alternatives have included devices in which a solid or liquid fuel is burned to transfer heat to the tobacco or in which a chemical reaction is used to provide such a heat source. An example is the smoking article described in U.S. Patent No. 9,078,473 to Worm et al., which is hereby incorporated by reference in its entirety.

[0004] The point of improvement or alternatives to smoking products has typically been to provide the sensation associated with cigarette, cigar, or pipe smoking without delivering a significant amount of incomplete combustion and pyrolysis products. To this end, numerous smoking products, aroma generators, and medical inhalers have been proposed that attempt to provide the sensation of cigarette, cigar, or pipe smoking without utilizing electrical energy to vaporize or heat volatile substances or without burning tobacco to a significant degree. See, for example, the various alternative smoking products, aerosol delivery devices, and heat sources described in the background art of U.S. Patent No. 7,726,320 by Robinson et al., U.S. Patent Application Publication No. 2013 / 0255702 by Griffith Jr. et al., and U.S. Patent Application Publication No. 2014 / 0096781 by Sears et al., which are incorporated herein by reference. See also, for example, the various types of smoking products, aerosol delivery devices, and electric heat sources referenced by brand names and commercial sources in U.S. Patent Application Publication No. 2015 / 0220232 by Bless et al., which is incorporated herein by reference. Additional types of smoking products, aerosol delivery devices, and electric heat sources referenced by brand names and commercial sources are enumerated in U.S. Patent Application Publication No. 2015 / 0245659 by DePiano et al., which is incorporated herein by reference in its entirety.Other representative tobacco or smoking products described and, in some cases, commercially available are incorporated herein by reference: U.S. Patent No. 4,735,217 by Gerth, U.S. Patent No. 4,922,901 by Brooks, U.S. Patent No. 4,947,874 and U.S. Patent No. 4,947,875 by Counts, U.S. Patent No. 5,060,671 by Counts, U.S. Patent No. 5,249,586 by Morgan, and U.S. Patent No. 5,388 by Counts.

This includes the specifications described in Patent Application Publication No. 2009 / 0272379, U.S. Patent Application Publication Nos. 2009 / 0260641 and 2009 / 0260642 by Monsees et al., U.S. Patent Application Publication Nos. 2008 / 0149118 and 2010 / 0024834 by Oglesby et al., U.S. Patent Application Publication No. 2010 / 0307518 by Wang, and International Publication No. 2010 / 091593 by Hon.

[0005] Various methods and techniques have been proposed for assembling smoking products having multiple segmented components arranged in a continuous manner. For example, see the various types of assembly techniques and methodologies described in Barnes et al. U.S. Patent No. 5,469,871, Crooks et al. U.S. Patent No. 7,647,932, Crooks et al. U.S. Patent Application Publication No. 2010 / 0186757, Stone et al. U.S. Patent Application Publication No. 2012 / 0042885, and Conner et al. U.S. Patent Application Publication No. 2012 / 00673620, which are incorporated herein by whole reference.

[0006] Certain types of cigarettes that use carbonaceous fuel elements are marketed by RJ Reynolds Tobacco Company under the brand names "Premier," "Eclipse," and "Revo." See, for example, the descriptions of these types of cigarettes in *Chemical and Biological Studies on New Cigarette Prototypes that Heat Instead of Burn Tobacco*, RJ Reynolds Tobacco Company Monograph (1988) and *Inhalation Toxicology*, 12:5, pp. 1-58 (2000). Similar cigarettes are also sold in Japan by Japan Tobacco Inc. under the brand name "Steam Hot One."

[0007] In some cases, certain smoking products, particularly those using conventional packaging materials, are prone to charring of the packaging material covering the ignitable fuel source due to the high temperatures achieved by the fuel source in close proximity to the packaging material. This may reduce the enjoyment of the smoking experience for some consumers and may mask or alter the flavor delivered to the consumer by the aerosol-delivering components of the smoking product. In further examples, conventional types of smoking products may produce relatively significant levels of gases during use, such as carbon monoxide and / or carbon dioxide (e.g., as products of carbon combustion). In yet another example, conventional types of smoking products may have problems with poor performance in aerosolizing the aerosol-forming components(s). [Prior art documents] [Patent Documents]

[0049] This disclosure is described more thoroughly below with reference to its embodiments. These embodiments are described in such a way that the disclosure is thorough and complete and conveys the full scope of the disclosure to those skilled in the art. In fact, this disclosure is embodied in many different forms and should not be construed as being limited to the embodiments described herein, but rather these embodiments are provided to satisfy the legal requirements to which the disclosure is applicable. As used herein and in the appended claims, the singular forms "a," "an," and "the" refer to plural subjects unless otherwise explicitly indicated in the context.

[0050] This disclosure provides a description of articles (and their assemblies and / or manufactures) in which a material is heated (preferably without burning the material to a significant degree) to form an aerosol and / or inhalable substance, and such articles are most preferably compact enough to be considered “handheld” devices. In a preferred embodiment, the article is characterized as a smoking article. As used herein, the term “smoking article” is intended to mean an article and / or device that provides many of the sensations of smoking a cigarette, cigar, or pipe (e.g., the act of inhaling and exhaling, the type of taste or flavor, the sensory effect, the physical sensation, the act of use, the markers such as those provided by a visible aerosol) without any component of the article and / or device being substantially burned. As used herein, the term “smoking product” does not necessarily mean that an article or device produces smoke in the sense of an aerosol resulting from the byproducts of the combustion or pyrolysis of tobacco during operation, but rather that an article or device produces vapor (including vapor in an aerosol that is considered to be a visible aerosol that is considered to be described as smoke-like) resulting from the volatilization or vaporization of certain components, elements, etc., of the article and / or device. In a preferred embodiment, an article or device characterized as a smoking product incorporates tobacco and / or tobacco-derived components.

[0051] As described above, the aerosol-generating components of certain preferred aerosol delivery devices can provide many of the sensations of smoking a tobacco, cigar, or pipe (e.g., the act of inhaling and exhaling, the type of taste or flavor, the sensory effects, the sensation, the act of use, the markers provided by the visible aerosol, etc.) without burning any component to any substantial degree, where the tobacco, cigar, or pipe is used by igniting and burning the tobacco (and thus inhaling the tobacco smoke). For example, a user of an aerosol delivery device according to some embodiments of the present disclosure can hold and use its components as a smoker uses a traditional type of smoking product, drawing in at one end of the component for inhalation of the aerosol generated by the component, or taking puffs at selected time intervals (smoking and exhaling the tobacco).

[0052] The articles or apparatus of this disclosure are also characterized by being vapor products, aerosol delivery articles, or drug delivery articles. Such articles or apparatus are adaptable to provide one or more substances in an inhalable form or state. For example, the inhalable substance is substantially in vapor form (e.g., a substance in the gas phase at a temperature below its critical point). Alternatively, the inhalable substance is in aerosol form (e.g., a suspension of fine solid particles or droplets in a gas). For simplicity, the term “aerosol” as used herein means including vapors, gases, and aerosols in forms or types suitable for human inhalation, whether visible or not, and whether in a form considered fuzzy or smoke-like. In some embodiments, the terms “vapor” and “aerosol” may be interchangeable. Therefore, for simplification, the terms “vapor” and “aerosol” as used to describe this disclosure are understood to be interchangeable unless otherwise specified.

[0053] In use, the smoking product of this disclosure elicits many of the same physical reactions from an individual as when using traditional types of smoking products (e.g., cigarettes, cigars, or pipes, which are used by lighting them with a flame and then inhaling the burning tobacco). For example, a user of the smoking product of this disclosure holds the item like a traditional type of smoking product, draws one end of the item in for inhalation of the aerosol produced by the item, and puffs at selected time intervals.

[0054] While the system is generally described herein in relation to embodiments relating to smoking products such as so-called "heated tobacco products," it should be understood that the mechanisms, components, features, and methods may be implemented in many different forms and associated with various articles. For example, the descriptions provided herein may be used in combination with conventional smoking products (e.g., cigarettes, cigars, pipes, etc.), non-combustible heated tobacco, and related packaging embodiments of any of the products disclosed herein. Therefore, the descriptions of mechanisms, components, features, and methods disclosed herein are described merely as examples relating to embodiments of aerosol delivery devices and should be understood as being able to be embodied and used in various other products and methods.

[0055] The smoking articles of this disclosure generally include several elements that are provided or housed within some kind of enclosure, such as a housing, outer wrap, or packaging, casing, components, modules, or members. The overall design of the enclosure is variable, and the form or configuration of the enclosure that defines the overall size and shape of the smoking article is also variable. In some embodiments, it is desirable that the overall design, size, and / or shape of the enclosure resemble that of a conventional cigarette or cigar. Typically, an enclosure that resembles the shape of a cigarette or cigar comprises separable components, members, etc. that engage to form the enclosure. For example, in some embodiments, such a smoking article may comprise separable components including a holder and a cartridge containing an aerosol delivery component (e.g., a substrate, etc.) and a heat source component. In various embodiments, the heat source may generate heat to aerosolize a substrate comprising, for example, an extruded structure and / or substrate, a substrate related to an aerosol precursor composition, tobacco and / or tobacco-related materials, such as materials naturally found in tobacco, isolated directly from tobacco or synthetically prepared, in solid or liquid form (e.g., beads, sheets, strips, wraps). In some embodiments, the extruded structure may contain a tobacco product or a tobacco composite with other materials, such as ceramic powder. In other embodiments, a tobacco extract / slurry may be filled into porous ceramic beads. In other embodiments, a non-tobacco product may be used. In some embodiments, porous beads / powder (ceramic) filled with the aerosol precursor composition may be used. In other embodiments, a rod / cylinder made of ceramic powder and an extruded slurry of the aerosol precursor composition may be used.

[0056] In certain aspects of this disclosure, it may be advantageous to provide an aerosol delivery device that is easy to use and provides reusable and / or replaceable components. Such a device is shown in Figure 1. In particular, Figure 1 shows a perspective view of an aerosol delivery device 100 according to an embodiment of this disclosure.

[0057] As shown in the figures, the illustrated embodiment of the aerosol delivery device 100 comprises a holder 200 including a first body portion 300 and a second body portion 400, and a removable and replaceable cartridge 500 (described in more detail below with respect to Figures 7 and 8). In the illustrated embodiment, the holder 200 (including the first body portion 300 and the second body portion 400) has a substantially rectangular overall shape. However, in other embodiments, the holder or any of its components may have different shapes. For example, in some embodiments, the holder (and / or any of its components) may have a substantially cylindrical shape that mimics the shape of a conventional cigarette. For example, in some embodiments, the holder (and / or any of its components) may have a substantially rectangular shape, such as a substantially rectangular cuboid shape. In other embodiments, the holder (and / or any of its components) may have other handheld shapes. For example, in some embodiments, the holder (and / or any of its components) may have a small box shape, various pod mod shapes, or fob shapes.

[0058] As best shown in Figures 2A and 2B, which show a perspective view of the first body portion 300 of the aerosol delivery device 100 in Figure 1, the first body portion 300 defines a distal end 302 and an opposite inhalation end 304, and a longitudinal axis L extending through them. In the illustrated embodiment, the first body portion 300 further defines a rotating pin 305 and a rotating axis R substantially aligned with the rotating pin 305. In the illustrated embodiment, the rotating pin 305 is located close to the distal end 302 of the first body portion 300. As will be described in more detail below, the rotating pin 305 is configured to facilitate the lateral rotation of the second body portion 400 relative to the first body portion 300. In other embodiments, the rotating pin may be located on the second body portion. In the illustrated embodiment, the first body portion 300 further includes a cavity 306 configured to receive at least a portion of the second body portion 400 when the holder 200 is in the use position. In the illustrated embodiment, the first body portion 300 tapers toward the mouthpiece end 304, but in other embodiments, the first body portion may have a substantially consistent shape toward the mouthpiece end. In the illustrated embodiment, the aerosol passage 308 is defined through the first body portion 300 and extends toward the cavity 306 toward the mouthpiece end 304. In the illustrated embodiment, the mouthpiece end 304 of the first body portion 300 includes a plurality of substantially circular openings 310 extending through it. However, in other embodiments, there may be a single opening having the same or different shapes, or a plurality of openings having different shapes.

[0059] In various embodiments, the first and / or second body parts may be made of a moldable plastic material such as polycarbonate, polyethylene, acrylonitrile butadiene styrene (ABS), polyamide (nylon), or polypropylene. However, in other embodiments, the first and / or second body parts may be made of different materials such as different plastic materials, metallic materials (e.g., but not limited to stainless steel, aluminum, brass, copper, silver, gold, or bronze), graphite materials, glass materials, ceramic materials, natural materials (e.g., but not limited to wood), composite materials, or any combination thereof. In the illustrated embodiment, the rotating pin 305 is a separate part from the first body part 300 and may be made of the same or different material (for example, in one embodiment, the first body part may be made of a moldable plastic material and the rotating pin may be made of a metallic material). However, in other embodiments, the rotating pin may be part of the first body part and therefore may be made of the same material.

[0060] Figures 3A and 3B show perspective views of the second body portion 400. As shown in the figures, the second body portion 400 defines a distal end 402 and a proximal end 404. In the illustrated embodiment, the second body portion 400 includes a body 406, a downstream extension 408 extending downstream from the body 406, and an upstream extension 409 extending upstream from the body 406. In the illustrated embodiment, at least a portion of the cartridge receiving chamber 410 is defined by the second body portion 400. In particular, in the illustrated embodiment, the cartridge receiving chamber 410 includes a groove 410a located in the downstream extension 408 which extends into a heat source space 412 located within the body 406 through an opening 410b. In the illustrated embodiment, the heat source of the inserted cartridge is configured to be located close to the heat source space 412 when the holder 200 is in the use position. In this way, the heat source may access oxygen supplied through a pair of openings 414 defined on both sides of the body 406 of the second body portion 400. In the illustrated embodiment, the openings 414 are substantially circular, although other embodiments may differ. Note that in some embodiments, the openings in the body may provide the user with access to ignite the heat source in the cartridge when the holder is in the use position. In some configurations, the openings and / or portions of the body portion adjacent to the openings may be made of and / or lined with heat-resistant material. In some configurations, this material may be the same as or different from the material of the rest of the body.

[0061] The second body portion 400 in the illustrated embodiment further includes a translation slot 416 configured to move relative to the rotating pin 305 of the first body portion 300. In particular, in the illustrated embodiment, the rotating pin 305 is fixed relative to the first body portion 300, and the translation slot 416 is configured to move relative to the fixed rotating pin 305. In the illustrated embodiment, the translation slot 416 is located in the downstream extension 408 of the second body portion 400, adjacent to the groove 410a of the cartridge receiving chamber 410 (for example, in Figures 3A and 3B below).

[0062] Figure 4 (showing a side view of the aerosol delivery device 100 of Figure 1 in the usage position) shows the movement of the second body portion 400 relative to the first body portion 300 when the second body portion 400 is moved from the usage position to the open position. For ease of explanation, the first body portion 300 in Figure 4 is shown as transparent. As shown in the figure, the downstream extension 408 of the second body portion 400 in the illustrated embodiment is configured to be received within the cavity 306 of the first body portion 300 when the holder 200 is in the usage position. Therefore, in the usage position, the distal end 416a of the translation slot 416 is located close to the rotating pin 305 of the first body portion 300 (as shown in Figure 4). To move the second body portion 400 to the open position, the second body portion 400 is moved substantially along the longitudinal axis L away from the first body portion 300 such that the downstream extension 408 of the second body portion 400 moves away from the cavity 306 of the first body portion 300 and the proximal end 416b of the translation slot 416 is positioned close to the rotation pin 305. In that position (or a position close thereto), the second body portion 400 can be rotated laterally to the open position about the rotation axis R such that the downstream extension 408 of the second body portion 400 is free from the first body portion 300 and the second body portion 400 is substantially perpendicular to the first body portion 300. In the open position, a removable and replaceable cartridge may be inserted into or removed from the cartridge receiving chamber of the second body portion 400. It should be noted that in various embodiments, the second body portion does not need to be perpendicular to the first body portion in the open position. Rather, in the open position, the second body portion only needs to be rotated so as to be sufficiently far from the first body portion to allow the cartridge to be inserted into or removed from the cartridge receiving chamber.

[0063] The holder 200 in the illustrated embodiment is configured such that, in the open position, a removable and replaceable cartridge can be inserted into or removed from the cartridge receiving chamber, and in the use position, a removable and replaceable cartridge can be held within the cartridge receiving chamber. In various embodiments, cartridge retention can be achieved in various different ways, but in the illustrated embodiment, this is achieved via a cartridge retention mechanism including one component located in the first body portion 300 and the other component located in the second body portion 400. Figure 5, which shows a side view of the aerosol delivery device 100 of Figure 1, further illustrates the retention mechanism of the illustrated embodiment. For ease of explanation, parts of the first body portion 300 and the second body portion 400 in Figure 5 are shown as transparent. In the illustrated embodiment, the removable and replaceable cartridge 500 is held using a first elastic member 320 located in the first body portion 300 and a second elastic member 420 located in the second body portion. In particular, the first elastic member 320 is positioned in the cavity 306 of the first body portion 300, close to the aerosol passage 308, and the second elastic member 420 is positioned between the downstream extension 408 and the body 406 of the first body portion 400, close to the opening 410b of the cartridge receiving chamber 410. In this way, the removable and receivable cartridge 500 is configured to extend through the second elastic member 420 and contact at least the first elastic member 320 when in the use position. Other configurations are possible, but in the illustrated embodiment, the first elastic member 320 and the second elastic member are equipped with O-rings made of rubber material. The inner diameter of the second elastic member 420 in the illustrated embodiment is larger than the inner diameter of the first elastic member 320. Similarly, the outer diameter of the second elastic member 420 is larger than the outer diameter of the first elastic member 320.

[0064] As described above, in other embodiments, the retaining mechanism may have other configurations. For example, in some embodiments, the retaining mechanism may comprise one or more retaining spheres and / or one or more cam surfaces. In other embodiments, the outer housing of the cartridge and / or holder may include one or more projections and / or spring mechanisms and corresponding retaining mechanisms configured to hold the cartridge in the receiving chamber in the use position. In other embodiments, the inner surface of the receiving chamber may have one or more portions having a decreasing diameter and / or a reduced diameter, which can be configured to hold the cartridge in the receiving chamber in the use position. In other embodiments, the holder may include a retractable mechanism configured to engage with the cartridge and hold the cartridge in the receiving chamber in the use position. In other embodiments, the holder may include one or more wedge mechanisms configured to engage with and hold the cartridge in the receiving chamber in the use position. In yet another embodiment, one or more features of the cartridge and / or one or more features of the holder may form a releasable connection between the receiving chamber and the cartridge. For example, in some embodiments, the cartridge and the receiving chamber may have a releasable screw connection. In yet another embodiment, the cartridge may be held in the receiving chamber via magnetic force. For example, in some embodiments, the outer housing of the cartridge may be made of a ferromagnetic material, and the receiving chamber may contain one or more magnets. Thus, in the illustrated embodiment, part of the cartridge holding mechanism is located in the first body portion 300 and part of the cartridge holding mechanism is located in the second body portion 400, but in other embodiments, the cartridge holding mechanism may be located in only the first body portion or only the second body portion.

[0065] The second body portion 400 of the illustrated embodiment further includes the plunger assembly 450 shown in Figure 6. In the illustrated embodiment, the plunger assembly 450 includes a spring member 452 and a pusher 454 comprising an end cap 454a and a post 454b extending therefrom. The post 454b of the illustrated embodiment further includes a post end 454c defined distal to the end cap 454a. In the illustrated embodiment, the plunger assembly 450 is positioned close to the upstream extension 409 of the second body portion 400. In particular, in the illustrated embodiment, at least a portion of the spring member 452 and the post 454b of the pusher 454 are located inside the upstream extension 409. In the illustrated embodiment, one end of the spring member 452 abuts against the internal cavity of the pusher 454, and the other end of the spring member 452 is held within the second body portion 400. In this way, the plunger 454 is spring-loaded such that the post 454a moves inward within the upstream extension 409. Thus, when the removable and replaceable cartridge 500 is received in the receiving chamber 410 of the second body portion, the post end 454c of the plunger 454 is positioned in close proximity (but not necessarily in contact with) the heat source of the cartridge 500. When the plunger 454 is pressed inward (for example, toward the body 406 of the second body portion 400), the post end 454c of the plunger 454 is configured to come into contact with the cartridge 500, and in particular with the heat source of the cartridge 500. Therefore, as shown in the figure, when the second body portion 400 is in use or near the use position (for example, when the downstream extension 408 is located within, or at least partially within, the cavity 306 of the first body portion 300), the plunger 454 of the second body portion 400 may be pushed inward so that the post end 454c contacts the heat source in order to fully seat the cartridge 500 in the holding mechanism. On the other hand, when the holder 200 is in the open position (for example, when the downstream extension 408 of the second body portion 400 is away from the cavity 306 of the first body portion 300), the plunger 454 may be pushed inward so that the post end 454c contacts the heat source of the cartridge 500 in order to eject the inserted cartridge 500.For example, in the illustrated embodiment, when the holder is in the open position, the cartridge 500 may be held by a second elastic member 420 located on the second body portion 400. Thus, when the pusher 454 in the illustrated embodiment is pushed inward, the post end 454c comes into contact with the heat source and can push the cartridge through the second elastic member 420 of the second body portion 400 until the cartridge 500 separates from the second body portion 400, and thus ejects the cartridge.

[0066] When the device is in use and the cartridge is received by the holding mechanism, air can be drawn in by the user and flow through the cartridge to be delivered to the user. In some embodiments, air can enter the cartridge through the heating portion. In other embodiments (e.g., implementations in which the cartridge includes a non-porous barrier between the heating portion and the substrate), air can enter the cartridge in some region downstream of the heating portion. In yet another embodiment, some of the air may enter the cartridge through the heating portion, and some of the air may enter the cartridge in some region downstream of the heating portion. In some implementations, the first body portion and / or the second body portion may include one or more airflow channels that are substantially aligned with one or more airflow intake openings located downstream of the heating portion and extend through the outer housing of the cartridge.

[0067] In various embodiments, one or more components of the plunger assembly may be made of a moldable plastic material such as polycarbonate, polyethylene, acrylonitrile butadiene styrene (ABS), polyamide (nylon), or polypropylene. However, in other embodiments, one or more components of the plunger assembly may be made of different materials such as different plastic materials, metallic materials (e.g., but not limited to stainless steel, aluminum, brass, copper, silver, gold, or bronze), graphite materials, glass materials, ceramic materials, natural materials (e.g., but not limited to wood), composite materials, or any combination thereof. In the illustrated embodiment, the spring member 452 is a separate part from the plunger 454 and may be made of the same or different material (for example, in one embodiment, the plunger may be made of a moldable plastic material and the spring member may be made of a metallic material). However, in other embodiments, the spring member may be part of the plunger and therefore may be made of the same material.

[0068] It should be noted that in some embodiments, all or part of the plunger assembly may be configured to shorten the overall length of the aerosol delivery device. Thus, for example, in some embodiments, all or part of the plunger assembly may rotate relative to the second body portion. For example, in some embodiments, all or part of the plunger assembly may rotate relative to the body of the second body portion so that all or part of the plunger assembly can be concealed until needed. In some embodiments, the aerosol delivery device may include one or more mechanisms configured to conceal the rotated plunger assembly. In other embodiments, all or part of the plunger assembly may be extendable or retractable to shorten the overall length of the plunger assembly. In some embodiments, the aerosol delivery device may include one or more mechanisms configured to conceal an extendable plunger assembly.

[0069] Figure 7 shows a perspective view of a removable and replaceable cartridge 500 according to an embodiment of the present disclosure. In the illustrated embodiment, the cartridge 500 defines a first end 502 and a distal end 504. The illustrated embodiment of the cartridge 500 further includes a heating portion 506 comprising a heat source 508, a base portion 510 comprising a base material 516 (see Figure 8), and an outer housing 512 configured to circumvent at least a portion of the heat source 508 and the base material 516. In the illustrated embodiment, the cartridge 500 has a substantially cylindrical overall shape, but it should be noted that in various other embodiments, the cartridge or any of its components may have a different shape. For example, in some embodiments, the cartridge (and / or any of its components) may have a substantially rectangular shape, such as a substantially rectangular cuboid shape. In other embodiments, the cartridge (and / or any of its components) may have a different handheld shape. Some examples of cartridge configurations that may be applicable to this disclosure can be found in U.S. Patent Application No. 16 / 515,637, filed on 18 July 2019, entitled "Aerosol Delivery Device with Consumable Cartridge," which is incorporated herein by reference in its entirety.

[0070] In some embodiments, a barrier may be present between the heat source and the substrate. In some embodiments, such a barrier may comprise a disc that may include one or more openings. In some embodiments, the barrier may be composed of a metallic material (e.g., stainless steel, aluminum, brass, copper, silver, gold, and bronze), or a graphite material, or a ceramic material, or a plastic material, or any combination thereof. In some embodiments, a heat transfer component may or may not be present between the heat source and the substrate. Some examples of heat transfer components are described in U.S. Patent Application No. 15 / 923,735, filed March 16, 2018, entitled “Smoking Article with Heat Transfer Component,” which is incorporated herein by reference in its entirety. In some embodiments, the barrier or heat transfer component may prevent and / or block combustion gases from being drawn through the substrate (and / or through an air passage into which aerosols are drawn).

[0071] In various embodiments, the heat source may be configured to generate heat upon ignition. In the illustrated embodiment, the heat source 508 has a substantially cylindrical shape and comprises a combustible fuel element incorporating a combustible carbonaceous material. In other embodiments, the heat source may have a different shape, for example, a prism shape with a cubic or hexagonal cross-section. Carbonaceous materials generally have a high carbon content. Some carbonaceous materials may consist mainly of carbon and / or typically have a carbon content of more than about 60%, generally more than about 70%, often more than about 80%, and most commonly more than about 90% on a dry weight basis.

[0072] In some cases, the heat source may incorporate elements other than combustible carbonaceous materials (e.g., tobacco components such as powdered tobacco or tobacco extract, flavorings, salts such as sodium chloride, potassium chloride and sodium carbonate, heat-stable hollow cylindrical (e.g., tubular) graphite fibers, iron oxide powder, glass filaments, powdered calcium carbonate, alumina granules, ammonia sources such as ammonia salts, and / or binders such as guar gum, ammonium alginate and sodium alginate). In other embodiments, the heat source may comprise multiple ignitable objects, such as multiple ignitable beads. It should be noted that in other embodiments, the heat source may have a different composition or relative content than those described above. For example, in some embodiments, different forms of carbon, such as graphite or graphene, can be used as the heat source. In other embodiments, the heat source may have increased levels of activated carbon, different carbon porosity, different amounts of carbon, blends of any of the above components, etc. In yet another embodiment, the heat source may comprise a non-carbon heat source, such as a combustible liquefied gas configured to generate heat upon ignition. For example, in some embodiments, the liquefied gas may include one or more of the following: petroleum gas (LPG or LP gas), propane, propylene, butylene, butane, isobutene, methylpropane, or n-butane. In yet other embodiments, the heat source may be a chemical reaction-based heat source, and the ignition of the heat source involves the interaction of two or more individual components. For example, a chemical reaction-based heat source may contain a metal agent and an activating solution, and the heat source is activated when the metal agent and the activating solution come into contact. Several examples of chemical-based heat sources can be found in U.S. Patent No. 7,290,549 by Banerjee et al., which is incorporated in whole herein by reference. Combinations of heat sources are also possible. The specific dimensions of the applicable heat source can vary, but in the illustrated embodiment, the heat source 508 has a length in the range of about 5 mm to about 20 mm, which may be about 12 mm in some embodiments, and an overall diameter in the range of about 3 mm to about 8 mm, which may be about 4.8 mm (about 7 mm in some embodiments).

[0073] In other embodiments, the heat source may be constructed in various ways, but in the illustrated embodiment, the heat source 508 is extruded or compounded using crushed or powdered carbonaceous material at a dry weight of about 0.5 g / cm³. 3 It exceeds, often around 0.7 g / cm³ 3 Exceeding approximately 1 g / cm³, often around 1 g / cm³ 3 It has a density exceeding [a certain value]. For example, see the types of fuel source components, formulations and designs described in U.S. Patent No. 5,551,451 by Riggs et al. and U.S. Patent No. 7,836,897 by Borschke et al., which are incorporated herein by reference in their entirety.

[0074] In various embodiments, the heat source may have various forms, including, for example, a substantially solid cylindrical shape or a hollow cylindrical (e.g., tubular) shape, but the heat source 508 in the illustrated embodiment contains an extruded monolithic carbonaceous material having a substantially cylindrical shape and including a plurality of internal passages 514 that extend longitudinally from a first end of the heat source 508 to a second end on the opposite side of the heat source 508. In the illustrated embodiment, there are about 13 internal passages 514, including a single central internal passage 514a, six peripheral internal passages 514b spaced apart from the central internal passage 514a and having a similar size (e.g., diameter) to the central internal passage 514a, and six peripheral internal passages 514c spaced apart from the outer surface of the heat source 508 and having a smaller diameter than the central internal passage 514a. Note that in other embodiments, the plurality of internal passages are not required, and / or the plurality of internal passages can take other forms and / or sizes. For example, some embodiments may have as few as two internal passages, and yet other embodiments may include as few as one internal passage. Still other embodiments may not include any internal passages at all. Additional embodiments may include multiple internal passages, which may have uneven diameters and / or shapes, be unevenly spaced, and / or be arranged within a heat source.

[0075] Some embodiments may, alternatively or additionally, include one or more peripheral grooves extending longitudinally from a first end to a second end opposite the heat source, while in other embodiments the grooves do not need to extend along the entire length of the heat source. In some embodiments, such grooves may be substantially equal in width and depth and substantially equally distributed around the circumference of the heat source. In such embodiments, there may be as few as two grooves, and in yet another embodiment, there may be as few as one groove. Still another embodiment may have no grooves at all. Additional embodiments may include multiple grooves, which may have uneven width and / or depth and be unevenly spaced around the circumference of the heat source. In yet another embodiment, the heat source may include grooves and / or slits extending longitudinally from a first end to a second end opposite the extruded monolithic carbonaceous material. In some embodiments, the heat source may contain a foamed carbon monolith formed by a foaming process of the type disclosed in Lobovsky's U.S. Patent No. 7,615,184, which is incorporated herein by reference in whole. Accordingly, some embodiments may offer advantages in terms of reducing the time required to ignite the heat source. In some other embodiments, the heat source may be co-extruded with an insulating layer (not shown), thereby reducing manufacturing time and cost. Other embodiments of the fuel element include carbon fiber of the type described in Brooks et al. U.S. Patent No. 4,922,901, or other heat source embodiments such as those disclosed in Takeuchi et al. U.S. Patent Application Publication No. 2009 / 0044818, each of which is incorporated herein by reference in its entirety. Further examples of heat sources, including debossed heat source systems, methods, and smoking articles containing such heat sources, are disclosed in U.S. Patent Application No. 15 / 902,665, filed on 22 February 2018, entitled "System for Debossing a Heat Generation Member, a Smoking Article Including the Debossed Heat Generation Member, and a Related Method," which is incorporated herein by reference in its entirety.

[0076] Generally, the heat source is positioned close enough to an aerosol delivery component (e.g., a base component) having one or more aerosolizable components so that the aerosol formed / volatilized by the application of heat from the heat source to the aerosolizable components (as well as any flavorings, drugs, etc., similarly provided for delivery to the user) can be delivered to the user via the mouthpiece. That is, when the heat source heats the base component, an aerosol is formed, released, or generated in a physical form suitable for inhalation by the consumer. It should be noted that the terms used herein are intended to be interchangeable, including form or generate, forming or generating, forms or generates, and formed or generated. Specifically, the inhalable substance is released in the form of a vapor or aerosol or a mixture thereof. Furthermore, the selection of various smoking components is understood in consideration of commercially available e-smoking products, such as the representative products listed in the background technology section of this disclosure.

[0077] Figure 8 shows a longitudinal cross-sectional view of the cartridge 500 of Figure 7. As shown in the figure, the base material 516 in the illustrated embodiment has first and second ends opposite to each other, and the heat source 508 is positioned adjacent to the first end of the base material 516. The dimensions of the various components of the cartridge may vary depending on the needs of the particular application, but in the illustrated embodiment, the cartridge 500 may have an overall length in the range of about 10 mm to about 50 mm and a diameter in the range of about 2 mm to about 20 mm. Furthermore, in the illustrated embodiment, the outer housing 312 may have a thickness in the range of about 0.05 mm to 0.5 mm. Furthermore, in the illustrated embodiment, the base material portion 510 may have a length in the range of about 5 mm to 30 mm and a diameter slightly smaller than the overall diameter of the cartridge, for example, in the range of about 2.9 mm to about 9.9 mm, to correspond to the thickness of the housing 512. In the illustrated embodiment, the base material 516 includes tobacco beads which may have a diameter size in the range of about 0.5 mm to 2.0 mm, but in other embodiments, the size may differ. In other embodiments, the base material may be granular tobacco material or cut filler tobacco. Other embodiments may differ, but in the illustrated embodiment, the outer housing 512 of the cartridge 500 is filled to about 80-90% capacity to allow insertion of the heat source 508.

[0078] In the illustrated embodiment, the substrate portion 510 comprises a substrate 516 having a single segment, but in other embodiments, the substrate portion may include one or more additional substrate segments. For example, in some embodiments, the aerosol delivery device may further include a second substrate segment (not shown) having first and second ends opposite to each other. In various embodiments, one or more substrates may include tobacco or tobacco-related material associated with the aerosol precursor composition. In other embodiments, non-tobacco materials such as cellulose pulp material may be used. In other embodiments, the non-tobacco substrate may not be a plant-derived material. Other possible compositions, components, and / or additives for use in the substrate (and / or multiple substrates) are described in more detail below. Note that the following description is applicable to any substrate available for use in the smoking products described herein (e.g., substrate 516 in the illustrated embodiment).

[0079] In the illustrated embodiment, ignition of the heat source 508 results in the aerosolization of the aerosol precursor composition associated with the substrate 516. In various embodiments, the aerosol passage 308 is configured to receive the generated aerosol through it in response to a draw applied by the user to the suction end 304 of the first body portion 300. In some implementations, the suction end 304, or another part of the first body portion 300, may include a filter configured to receive the aerosol in response to a draw applied to the suction end 304 of the first body portion. In various embodiments, the filter may be provided as a circular disk positioned radially and / or longitudinally adjacent to the end of the holder opposite the receiving end, in some aspects. Thus, when drawn in at the suction end 304 of the first body portion 300, the filter may receive the aerosol flowing through the holder 200 of the aerosol delivery device 100. In some embodiments, the filter may comprise separate segments. For example, some embodiments may include a segment that provides filtration, a segment that provides draw resistance, a hollow segment that provides space for the aerosol to cool, other filter segments, and any one or any combination of the above. In some implementations, the mouthpiece may also include a filter that may also provide flavoring additives. In some embodiments, the filter may include one or more filter segments that can be replaced. For example, in some embodiments, one or more filter segments, for example, including filter segments that provide different draw resistance and / or different flavors, may be replaced to customize the user experience with the device.Some examples of flavoring materials and / or components configured to add fragrance can be found in U.S. Patent Application No. 16 / 408,942, filed on 10 May 2019 and titled "Flavor Article for an Aerosol Delivery Device," U.S. Patent Application No. 15 / 935,105, filed on 26 March 2018 and titled "Aerosol Delivery Device Providing Flavor Control," and U.S. Patent Application No. 16 / 353,556, filed on 14 March 2019 and titled "Aerosol Delivery Device Providing Flavor Control," each of which is incorporated herein by reference in its entirety.

[0080] Preferably, the elements of the substrate do not undergo significant thermal decomposition (e.g., carbonization, charring, or combustion), and the aerosolized components are entrained in the air drawn into the user's mouth through the smoking article, including a filter (if present). In the smoking article 100 of the illustrated embodiment, the substrate 516 contains a plurality of tobacco beads formed together in a substantially cylindrical portion. However, in various embodiments, the substrate may contain a variety of different compositions and combinations thereof, as will be described in more detail below.

[0081] In various embodiments, the base material may contain tobacco material, non-tobacco material, or a combination thereof. In one embodiment, for example, the base material may contain a flavorful, highly aromatic tobacco blend in the form of a cut filler. In another embodiment, the base material may contain reconstituted tobacco material as described in U.S. Patent No. 4,807,809 by Pryor et al., U.S. Patent No. 4,889,143 by Pryor et al., and U.S. Patent No. 5,025,814 by Raker, the disclosures of which are incorporated herein by reference in their entirety. Furthermore, the reconstituted tobacco material may include reconstituted tobacco paper for the type of cigarette described in Chemical and Biological Studies on New Cigarette Prototypes that Heat Instead of Burn Tobacco, RJ Reynolds Tobacco Company Monograph (1988), the contents of which are incorporated herein by reference in their entirety. For example, the reconstituted tobacco material may include a sheet-like material containing tobacco and / or tobacco-related material. Thus, in some embodiments, the base material may be formed from a rolled reconstituted tobacco material. In certain embodiments, the substrate may be formed from fragments, strips, or the like of a reconstituted tobacco material. In another embodiment, the tobacco sheet may comprise overlapping layers (e.g., a gathered web) which may or may not include heat-conducting components. An example of a substrate portion comprising a series of overlapping layers (e.g., a gathered web) of an initial substrate sheet formed from a fibrous filler material, an aerosol-forming material, and a plurality of heat-conducting components is described in U.S. Patent Application No. 15 / 905,320, filed on 26 February 2018, entitled "Heat Conducting Substrate for Electrically Heated Aerosol Delivery Device," which is incorporated herein by reference in its entirety.

[0082] In some embodiments, the substrate may include a plurality of microcapsules, beads, granules, etc., having tobacco-related material. For example, a typical microcapsule may be substantially spherical in shape and may have an outer cover or shell containing a liquid central region such as a tobacco-derived extract. In some embodiments, one or more substrates may include a plurality of microcapsules, each formed in a hollow cylindrical shape. In some embodiments, one or more substrates may include a binder material configured to maintain the structural shape and / or integrity of the plurality of microcapsules formed in a hollow cylindrical shape.

[0083] The tobacco used in one or more of the base materials may include, or be derived from, yellow tobacco, Burley tobacco, Oriental tobacco, Maryland tobacco, dark tobacco, dark tumbled tobacco and Rustika tobacco, as well as other rare or special tobaccos, or blends thereof. Various representative tobacco types, processed tobacco types, and tobacco blend types are described in U.S. Patent No. 4,836,224 by Lawson et al., U.S. Patent No. 4,924,888 by Perfetti et al., U.S. Patent No. 5,056,537 by Brown et al., U.S. Patent No. 5,159,942 by Brinkley et al., U.S. Patent No. 5,220,930 by Gentry et al., U.S. Patent No. 5,360,023 by Blakley et al., U.S. Patent No. 6,701,936 by Shafer et al., Doming These disclosures are described in U.S. Patent No. 6,730,832 by Uez et al., U.S. Patent No. 7,011,096 by Li et al., U.S. Patent No. 7,017,585 by Li et al., U.S. Patent No. 7,025,066 by Lawson et al., U.S. Patent Application Publication No. 2004 / 0255965 by Perfetti et al., International Application No. 02 / 37990 by Bereman, and Bombick et al., Fund.Appl.Toxicol., 39, pp. 11-17 (1997), and these disclosures are incorporated herein by reference in their entirety.

[0084] In yet another embodiment of this disclosure, the substrate may comprise an extruded structure containing or essentially composed of tobacco, tobacco-related materials, glycerin, water, and / or a binder material, although certain formulations may exclude the binder material. In various embodiments, suitable binder materials may include alginates such as ammonium alginate, propylene glycol alginate, potassium alginate, and sodium alginate.

Further possible binder materials include starch (e.g., corn starch), guar gum, carrageenan, locust bean gum, pectin, and xanthan gum. In some embodiments, a combination or blend of two or more binder materials may be used. Other examples of binder materials are described, for example, in U.S. Patent No. 5,101,839 by Jakob et al. and U.S. Patent No. 4,924,887 by Raker et al., each of which is incorporated herein by reference in whole. In some embodiments, the aerosol-forming material may be provided as part of the binder material (e.g., propylene glycol alginate). Furthermore, in some embodiments, the binder material may contain nanocellulose derived from tobacco or other biomass.

[0085] In some embodiments, the substrate may include an extruded material, as described in Stone et al., U.S. Patent Application Publication No. 2012 / 0042885, which is incorporated herein by reference in its entirety. In yet another embodiment, the substrate may include an extruded structure and / or substrate formed from marmelized and / or unmarmelized tobacco. Marmelized tobacco is known, for example, from Banerjee et al., U.S. Patent No. 5,105,831, which is incorporated herein by reference in its entirety. Marmelized tobacco includes a tobacco blend of about 20 to about 50% by weight in powder form, containing glycerol (about 20 to about 30% by weight) and calcium carbonate (generally about 10 to about 60% by weight, often about 40 to about 60% by weight), together with the binders and / or flavorings described herein. In various embodiments, the extruded material may have one or more longitudinal openings.

[0086] In various embodiments, the substrate can take on various structures based on the varying amounts of material used therein. For example, the sample substrate may contain up to about 98% by weight, up to about 95% by weight, or up to about 90% by weight of tobacco and / or tobacco-related materials. The sample substrate may also contain up to about 25% (by weight), about 20% (by weight), or about 15% (by weight) of water, particularly about 2% to about 25%, about 5% to about 20%, or about 7% to about 15% (by weight) of water. Flavorings and the like (including pharmaceuticals such as nicotine) may contain up to about 10% by weight, up to about 8% by weight, or up to about 5% by weight of aerosol delivery components.

[0087] Additionally or alternatively, the substrate may include an extruded structure and / or a substrate comprising, or essentially composed of, tobacco, glycerin, water, and / or a binder material, and further configured to substantially maintain its structure throughout the aerosol-generating process. That is, the substrate may be configured to substantially maintain its shape throughout the aerosol-generating process (e.g., the substrate does not deform continuously under applied shear stress). Such exemplary substrates may contain liquid and / or some water content, but the substrate may remain substantially solid throughout the aerosol-generating process and substantially maintain its structural integrity throughout the aerosol-generating process. Exemplary tobacco and / or tobacco-related materials suitable for substantially solid substrates are described in the U.S. Patent Application Publication No. 2015 / 0157052 by Ademme et al., U.S. Patent Application Publication No. 2015 / 0335070 by Sears et al., U.S. Patent No. 6,204,287 to White, and U.S. Patent No. 5,060,676 to Hearn et al., which are incorporated herein by reference in their entirety.

[0088] In some embodiments, the amount of base material used in the smoking product may be such that the product exhibits acceptable sensory and sensory stimulation characteristics, as well as desirable performance characteristics. For example, in some embodiments, an aerosol precursor composition, such as glycerin and / or propylene glycol, may be used in the base material to provide the generation of a visible mainstream aerosol that in many respects resembles the appearance of cigarette smoke. For example, the amount of aerosol precursor composition incorporated into the base material of the smoking product may be in the range of about 3.5 grams or less, about 3 grams or less, about 2.5 grams or less, about 2 grams or less, about 1.5 grams or less, about 1 gram or less, or about 0.5 grams or less.

[0089] In another embodiment, the smoking product according to the present disclosure may comprise a substrate containing a porous inert material, such as a ceramic material. For example, in some embodiments, ceramics of various shapes and geometric shapes (e.g., beads, rods, tubes, etc.) may be used, which have various pore morphologies. Furthermore, in some embodiments, non-tobacco materials, such as aerosol precursor compositions, may be filled into the ceramic. In another embodiment, the substrate may comprise a porous inert material that is substantially inactive chemically and / or physically with tobacco-related materials, such as tobacco-derived extracts. Furthermore, the extruded tobacco described above may be porous. For example, in some embodiments, the extruded tobacco material may have an inert gas, such as nitrogen, which acts as a foaming agent during the extrusion process.

[0090] As described above, in various embodiments, one or more of the substrates may include tobacco, tobacco components, and / or tobacco-derived materials that have been processed, manufactured, produced, and / or treated to incorporate an aerosol precursor composition (e.g., a lubricant, e.g., propylene glycol, glycerin, and / or similar) and / or at least one flavoring, as well as a flame retardant (e.g., diammonium phosphate and / or another salt) configured to help prevent ignition, thermal decomposition, combustion, and / or charring of the substrate by a heat source. Various methods and techniques for incorporating tobacco into smoking products, particularly those designed to intentionally prevent substantially all of the tobacco within these smoking products from burning, are described in U.S. Patent No. 4,947,874 by Brooks et al., U.S. Patent No. 7,647,932 by Cantrell et al., U.S. Patent No. 8,079,371 by Robinson et al., U.S. Patent No. 7,290,549 by Banerjee et al., and U.S. Patent Application Publication No. 2007 / 0215167 by Crooks et al., the disclosures thereof being incorporated herein by reference in their entirety.

[0091] As described above, in some embodiments, flame retardant materials and other additives may be included in one or more of the substrates and may include organophosphorus compounds, borax, hydrated alumina, graphite, potassium tripolyphosphate, dipentaerythritol, pentaerythritol, and polyols. Other suitable but undesirable agents include nitrogen phosphonates, monoammonium phosphate, ammonium polyphosphate, ammonium bromide, ammonium borate, ammonium ethanol borate, ammonium sulfamate, halogenated organic compounds, thiourea, and antimony oxide. In each embodiment of the flame retardant material used in the substrate and / or other components (alone or in combination with each other and / or other materials), the most preferred desirable properties are provided without undesirable off-gas or molten behavior.

[0092] According to other embodiments of this disclosure, the substrate may also incorporate tobacco additives of the types conventionally used in the manufacture of tobacco products. These additives may include types of materials used to enhance the flavor and aroma of tobacco used in the manufacture of cigars, cigarettes, pipes, etc. For example, these additives may include various cigarette casing and / or top dressing components. See, for example, U.S. Patent No. 3,419,015 by Wochnowski, U.S. Patent No. 4,054,145 by Berndt et al., U.S. Patent No. 4,887,619 by Burcham, Jr. et al., U.S. Patent No. 5,022,416 by Watson, U.S. Patent No. 5,103,842 by Strang et al., and U.S. Patent No. 5,711,320 by Martin, the disclosures of which are incorporated herein by reference in their entirety. Suitable casing materials may include water, sugars and syrups (e.g., sucrose, glucose, and high-fructose corn syrup), humectants (e.g., glycerin or propylene glycol), and flavorings (e.g., cocoa and licorice). These additive components may also include top dressing materials (e.g., flavorings such as menthol). See, for example, U.S. Patent No. 4,449,541 by Mays et al., the disclosure of which is incorporated herein by reference in its entirety. Further materials that may be added are disclosed in U.S. Patent No. 4,830,028 by Lawson et al. and U.S. Patent No. 8,186,360 by Marshall et al., the disclosures of which are incorporated herein by reference in their entirety.

[0093] In some embodiments, the substrate may contain a liquid and / or a gel containing an aerosol precursor composition. Some examples of liquid compositions can be found in U.S. Patent Application No. 16 / 171,920, filed October 26, 2018, entitled "Aerosol Delivery Device with Visible Indicator," which is incorporated herein by reference in its entirety.

[0094] As described above, in various embodiments, one or more of the substrates may have an associated aerosol precursor composition. For example, in some embodiments, the aerosol precursor composition may contain one or more different components, such as polyhydric alcohols (e.g., glycerin, propylene glycol, or mixtures thereof). Representative types of further aerosol precursor compositions are described in U.S. Patent No. 4,793,365 to Sensabaugh, Jr. et al., U.S. Patent No. 5,101,839 to Jakob et al., International Publication No. 98 / 57556 by Biggs et al., and Chemical and Biological Studies on New Cigarette Prototypes that Heat Instead of Burn Tobacco, RJ Reynolds Tobacco Company Monograph (1988), the disclosures of which are incorporated herein by reference. In some embodiments, the substrates may produce a visible aerosol when sufficiently heated (and cooled with air as necessary), or the substrates may produce a “smoky” aerosol. In other embodiments, the substrate may generate an aerosol that is substantially invisible but is perceived as present by other properties such as flavor or texture. Thus, the properties of the generated aerosol may vary depending on the specific components of the aerosol delivery components. The substrate may be chemically simple with respect to the chemical properties of the smoke produced by burning tobacco.

[0095] In some embodiments, the aerosol precursor composition may incorporate nicotine, which may be present at various concentrations. The source of nicotine may vary, and the nicotine incorporated into the aerosol precursor composition may originate from a single source or a combination of two or more sources. For example, in some embodiments, the aerosol precursor composition may contain nicotine derived from tobacco. In other embodiments, the aerosol precursor composition may contain nicotine derived from other organic plant sources, such as non-tobacco plant sources including, for example, plants of the Solanaceae family. In other embodiments, the aerosol precursor composition may contain synthetic nicotine. In some embodiments, the nicotine incorporated into the aerosol precursor composition may originate from non-tobacco plant sources, such as other members of the Solanaceae family. The aerosol precursor composition may additionally or alternatively contain other active ingredients, including but not limited to plant components (e.g., lavender, peppermint, chamomile, basil, rosemary, thyme, eucalyptus, ginger, cannabis, ginseng, maca, and dextrose), stimulants (e.g., caffeine and guarana), amino acids (e.g., taurine, theanine, phenylalanine, tyrosine, and tryptophan) and / or pharmaceutical, dietary supplement, and pharmaceutical components (e.g., vitamins, e.g., B6, B12, and C, and cannabinoids, e.g., tetrahydrocannabinol (THC) and cannabidiol (CBD)). Note that the aerosol precursor composition may contain any of the above components, derivatives, or combinations.

[0096] As described herein, the aerosol precursor composition may contain or be derived from one or more plant substances or their components, derivatives, or extracts. As used herein, the term “plant substance” includes, but is not limited to, any material derived from plants, including extracts, leaves, bark, fibers, stems, roots, seeds, flowers, fruits, pollen, peels, shells, etc. Alternatively, the material may contain naturally occurring active compounds in synthetically obtained plant substances. The material may be in the form of a liquid, gas, solid, powder, dust, crushed particles, granules, pellets, flakes, strips, sheets, etc. Examples of plants include tobacco, eucalyptus, star anise, hemp, cocoa, cannabis, fennel, lemongrass, peppermint, spearmint, rooibos, chamomile, flax, ginger, ginkgo, hazelnut, hibiscus, laurel, licorice, matcha, mate, orange peel, papaya, rose, sage, tea (such as green or black tea), thyme, cloves, cinnamon, coffee, anise, basil, laurel, cardamom, coriander, cumin, nutmeg, oregano, paprika, rosemary, saffron, and rabbi. These include corn, lemon peel, mint, juniper, elderflower, vanilla, chrysanthemum, shiso, turmeric, sandalwood, coriander leaves, bergamot, orange blossom, myrtle, blackcurrant, valerian, pimento, mace, damien, marjoram, olive, lemon balm, lemon basil, chives, calvi, verbena, tarragon, geranium, mulberry, carrot, theanine, theacrine, maca, ashwagandha, damiana, guarana, chlorophyll, baobab, or any combination thereof.Mint can be selected from the following mint varieties: Mentha Arventis, Mentha cv, Mentha niliaca, Mentha piperita, Mentha piperita citrata cv, Mentha piperita cv, Mentha spicata crispa, Mentha cardifolia, Mentha longifolia, Mentha suaveolens variegata, Mentha pulegium, Mentha spicata cv, and Mentha suaveolens.

[0097] A wide variety of flavorings, or materials that alter the sensory or sensory-stimulating properties or characteristics of the mainstream aerosol of a smoking product, may be suitable for use. In some embodiments, such flavorings may be supplied from sources other than tobacco and may be natural or artificial in nature. For example, some flavorings may be applied to or incorporated into the area of ​​the smoking product where the substrate and / or aerosol are produced. In some embodiments, such flavorings may be supplied directly to a heating cavity or area adjacent to a heat source, or the substrate may be provided. Examples of flavorings include, for example, vanillin, ethyl vanillin, cream, black tea, coffee, fruit (e.g., apple, cherry, strawberry, peach, and citrus flavors including lime and lemon), maple, menthol, mint, peppermint, spearmint, chrysanthemum, nutmeg, clove, lavender, cardamom, ginger, honey, anise, sage, cinnamon, sandalwood, jasmine, cascaria, cocoa, licorice, as well as flavors and flavor packages of types and characteristics traditionally used to flavor tobacco, cigars, and pipe tobacco. Syrups such as high-fructose corn syrup may also be suitable for use.

[0098] As used herein, terms such as “flavoring,” “flavoring,” and “fragrance” refer to materials that may be used to create a desired taste, aroma, or other somatosensory sensation in products intended for adult consumers, where local regulations permit it.These are naturally occurring flavorings, plants, plant extracts, synthetically obtained materials, or combinations thereof (e.g., tobacco, cannabis, licorice, hydrangea, eugenol, magnolia leaves, chamomile, fenugreek, clove, maple, matcha, menthol, mint, anise, cinnamon, turmeric, Indian spices, Asian spices, herbs, sedge, cherry, berries, red berries, cranberries, peaches, apples, oranges, mangoes, clementines, lemons, limes, tropical fruits, papaya, rhubarb). Grapes, durian, dragon fruit, cucumber, blueberry, mulberry, citrus fruits, Drambuie, bourbon, scotch, whiskey, gin, tequila, rum, spearmint, peppermint, lavender, aloe vera, cardamom, celery, cascarilla, nutmeg, sandalwood, bergamot, geranium, khat, naswar, betel nut, shisha, pine, honey, rose oil, vanilla, lemon oil, orange oil, orange blossom, cherry blossom, cassia, caraway, cognac, jasmine, ylang-ylang, sage, fennel, wasabi Mint oil from any type of plant, including bell pepper, ginger, coriander, coffee, hemp, mint, eucalyptus, star anise, cocoa, lemongrass, rooibos, flax, ginkgo, hazelnut, hibiscus, laurel, mate, orange peel, rose, tea such as green or black tea, thyme, juniper, elderflower, basil, laurel, cumin, oregano, paprika, rosemary, saffron, lemon peel, mint, shiso, curcuma, coriander leaves, myrtle, blackcurrant, valerian, pimento, mace, damien, maize It may also contain other additives such as chollum, olive, lemon balm, lemon basil, chives, calvi, verbena, tarragon, limonene, thymol, camphene), flavor enhancers, bitter taste receptor blockers, sensory receptor activators or stimulants, sugars and / or sugar substitutes (e.g., sucralose, acesulfame potassium, aspartame, saccharin, cyclamate, lactose, sucrose, glucose, fructose, sorbitol, or mannitol), as well as charcoal, chlorophyll, minerals, plant substances, or breath fresheners. These may be imitations, synthetic or natural ingredients or blends thereof.They may be in any suitable form, such as a liquid like oil, a solid like powder, or a gas.

[0099] In some embodiments, the flavor contains menthol, spearmint, and / or peppermint. In some embodiments, the flavor contains flavor components of cucumber, blueberry, citrus fruit, and / or red berry. In some embodiments, the flavor contains eugenol. In some embodiments, the flavor contains flavor components extracted from tobacco. In some embodiments, the flavor contains flavor components extracted from cannabis.

[0100] In some implementations, flavors may comprise, in addition to or instead of, olfactory or gustatory nerves, somatosensory sensations that are usually chemically induced and perceived by stimulation of the fifth cranial nerve (trigeminal nerve), and these may include agents that provide heating, cooling, stinging, or numbing effects. Suitable heating agents may include, but are not limited to, vanillyl ethyl ether, and suitable cooling agents may include, but are not limited to, eucalyptol or WS-3.

[0101] The flavorings may also contain acidic or basic characteristics (e.g., organic acids such as levulinic acid, succinic acid, pyruvic acid, and benzoic acid). In some embodiments, the flavorings may be combined with elements of the base material as needed. Suitable exemplary plant-derived compositions are disclosed in Dube et al., U.S. Patent No. 9,107,453 and U.S. Patent Application Publication No. 2012 / 0152265, which are incorporated herein by reference in their entirety. Any material such as flavorings, casings, etc., that may be useful in combination with a tobacco material to affect its sensory properties, including sensory stimulating properties as described herein, can be combined with the base material. Organic acids may be incorporated into the base material in particular to affect the flavor, sensation, or sensory stimulating properties of medicinal substances such as nicotine, which can be combined with the base material. For example, organic acids such as levulinic acid, lactic acid, pyruvic acid, and benzoic acid may be included in the base material together with nicotine in amounts up to equimolar (based on the total organic acid content) with nicotine. Any combination of organic acids may be suitable. For example, in some embodiments, the substrate may contain about 0.1 to about 0.5 moles of levulinic acid, about 0.1 to about 0.5 moles of pyruvate, about 0.1 to about 0.5 moles of lactic acid, or a combination thereof, per mole of nicotine, up to a concentration where the total amount of organic acids present is equimolar to the total amount of nicotine present in the substrate. Various additional examples of organic acids used to manufacture the substrate are described in U.S. Patent Application Publication No. 2015 / 0344456 by Dull et al., which is incorporated herein by reference in its entirety.

[0102] The selection of such further components may vary based on factors such as the desired sensory characteristics of the smoking product, and this disclosure is intended to encompass any such further components that are readily apparent to those skilled in the art of tobacco and tobacco-related or tobacco-derived products. See Gutcho, Tobacco Flavoring Substances and Methods, Noyes Data Corp. (1972) and Leffingwell et al., Tobacco Flavoring for Smoking Products (1972), the entirety of which is incorporated herein by reference.

[0103] In other embodiments, the substrate may include other materials having various unique features or properties. For example, the substrate may include regenerated cellulose in the form of a plasticizer or rayon. Another example that may be suitable is viscose (commercially available as VISIL(R)), which is a regenerated cellulose product incorporating silica. Some carbon fibers may contain at least 95% carbon. Similarly, natural cellulose fibers such as cotton may be suitable and may be impregnated with silica, carbon, or metal particles or otherwise treated in some way to enhance flame retardancy and minimize off-gas generation of any undesirable off-gas components that would adversely affect flavor in particular (in particular, minimizing the possibility of any toxic off-gas generation products). Cotton can be treated with, for example, boric acid or various organophosphate compounds, and desired flame retardancy can be provided by dipping, spraying, or other techniques known in the art. These fibers may also be treated with organic or metal nanoparticles (e.g., coated, impregnated, or both by dipping, spraying, or vapor deposition) to impart desired flame retardancy without undesirable off-gas generation or melt-type behavior.

[0104] In the illustrated embodiment, the substrate 516 may have a longitudinally extending axis defined centrally between the first and second opposite ends, and the cross-section of the substrate 516 may be symmetrical with respect to the axis in some embodiments. For example, in some embodiments, the cross-section of the substrate may be substantially circular so that the substrate defines a substantially cylindrical shape extending between its first and second opposite ends. However, in other embodiments, the substrate may define a substantially non-circular cross-section so that the substrate can define a substantially non-cylindrical shape between its first and second opposite ends. Otherwise, in other examples, the substrate may have an asymmetric cross-section with respect to the axis. In various embodiments, each end of the substrate may be axially aligned with an adjacent element.

[0105] As shown in Figures 7 and 8, the outer housing 512 of the illustrated embodiment of the cartridge 500 is configured to circumvent at least a portion of the substrate portion 510, which includes the substrate 516. In the illustrated embodiment, the outer housing 512 is also configured to circumvent at least a portion of the heat source 508. In some implementations, the outer housing may circumvent the entire heat source. In the illustrated embodiment, the outer housing comprises a rigid material. For example, the outer housing 512 in the illustrated embodiment is made of aluminum, but in other embodiments, the outer housing may be made of other materials, including other metallic materials (e.g., stainless steel, aluminum, brass, copper, silver, gold, and bronze), graphite materials, ceramic materials, plastic materials, or any combination thereof. In some embodiments, at least a portion of the heat source and / or at least a portion of the substrate may be circumvented by a foil laminate. In some embodiments, the cartridge may comprise an enclosure comprising a laminate including the heat source and the bead substrate. Some examples of laminates and / or enclosures that may be applicable to this disclosure can be found in U.S. Patent Application No. 16 / 174,846, “Smoking Article Cartridge,” filed on 30 October 2018, which is incorporated herein by reference in its entirety.

[0106] In the illustrated embodiment, the outer housing 512 is configured as a tubular structure substantially enclosing the substrate 516, but as described above, in other embodiments, the outer housing may have a different shape. The shape of the outer housing may be varied, but in the illustrated embodiment, the outer housing 512 comprises a tubular structure having an open end and a closed end. The illustrated embodiment of the outer housing 512 also includes one or more end openings 518 located at the closed end of the outer housing 512, configured to allow the passage of aerosolized vapor (referred to herein alternatively as “vapor” or “aerosol”). In the illustrated embodiment, the end openings 518 are in the form of a pair of elongated rounded slots, but in other embodiments, the end openings may have any shape that allows the passage of aerosol. It will be understood that the end openings 518 may have fewer or additional openings and / or openings of alternative shapes and sizes than those illustrated.

[0107] Thus, the holder of the present invention is configured to be movable between an open position and a use position. In various embodiments, the open position is configured to allow the user to insert and remove a cartridge. Note that in other embodiments, the holder of the present disclosure may include a third position which may be a fire extinguishing position. Thus, the fire extinguishing position may be configured such that the heat source is deprived of enough oxygen to sustain combustion. In some embodiments, the fire extinguishing position may be obtained by further movement of the second body portion. In other embodiments, for example, one or more additional mechanisms may be included, and the fire extinguishing position may be achieved by activating one or more additional mechanisms. In particular, in one embodiment, the device may include an air-impermeable cover mechanism positioned close to the distal end of the second body portion, which may be mechanically or manually actuated (for example, by sliding the cover mechanism over the opening of the second body portion) such that, in the fire extinguishing position, the cover mechanism substantially covers the opening of the second body portion and deprives the heat source of enough oxygen to sustain combustion. In another embodiment, the device may include a removable mechanism, such as an end cap, that can be used to achieve the fire extinguishing position. For example, in some embodiments, a separate end cap can be attached to at least a portion of the second body portion, and when attached, the heat source is deprived of enough oxygen to sustain combustion. Such an end cap can also be used to cover at least a portion of the second body portion when not in use, for example, to prevent dirt and / or foreign matter from entering the device. Additionally or alternatively, in some embodiments, the holder of the present disclosure may include a breathable cover mechanism (e.g., a cover feature including multiple openings, or a cover feature including a mesh) that protects the heat source in the use position.For example, in one embodiment, the holder may include an air-permeable cover mechanism positioned close to the distal end of the second body portion, which may be mechanically or manually actuated (e.g., by sliding the cover mechanism over the heat source space of the second body portion) so that, when ignited, the cover mechanism can be actuated to substantially cover the heat source space of the second body portion while maintaining sufficient access of oxygen to the heat source.

[0108] In the illustrated embodiment, the first body portion 300 and the second body portion 400 include substantially solid, non-porous walls, but in other embodiments, one or more of these walls may have other configurations. For example, in some embodiments, one or more walls of the first body portion or the second body portion may be non-solid and / or substantially porous, or may include one or more non-solid and / or substantially porous portions. In some implementations, for example, the second body portion may include one or more openings that can facilitate oxygen access to the heat source. Alternatively or additionally, other embodiments may include one or more openings that can mix with aerosols generated during intake. Thus, in the use position, one or more openings may be positioned close to the heat source, thus providing the heat source with additional access to oxygen during combustion. In some implementations, the first body portion may include one or more openings. For example, in some embodiments, the first body portion may include an opening extending into the aerosol passage of the first body portion so that air from outside the holder can mix with the aerosol generated by the base material.

[0109] In some implementations, the holder (e.g., the guide post and / or second body portion) may include a return mechanism configured to position the second body portion in the open and / or use position. In some embodiments, the holder may include one or more magnets configured to bias and / or position the second body portion in the open and / or use position. In some implementations, the holder may include one or more additional spring mechanisms configured to bias and / or position the second body portion in the open and / or use position. In some further embodiments, the holder may emit an audible click when the sleeve is positioned in the open and / or use position.

[0110] In various embodiments, this disclosure may relate to a kit providing various components described herein. For example, the kit may comprise a holder having one or more cartridges. In another embodiment, the kit may comprise a plurality of holders. In a further embodiment, the kit may comprise a plurality of cartridges. In yet another embodiment, the kit may comprise a plurality of holders and a plurality of cartridges. The kit of the present invention may further comprise a case (or other packaging, transport, or storage component) for housing one or more further kit components. The case may be a reusable rigid or flexible container. Furthermore, the case may simply be a box or other packaging structure. In some embodiments, a brush or other cleaning accessory may be included in the kit. The cleaning accessory may be configured to be inserted into a receiving chamber of the holder, or in other embodiments, into a separate opening that allows a user to remove debris from the receiving chamber.

[0111] Those skilled in the art will realize that many modifications and other embodiments of this disclosure have the same benefit as the teachings shown in the foregoing description and the accompanying drawings. Therefore, it should be understood that this disclosure is not limited to the specific embodiments disclosed herein, and that modifications and other embodiments are intended to be included within the scope of the appended claims. Certain terms are used herein, but they are used in a general and descriptive sense only and not for limitation.
