Patent Application
20220240571
The present disclosure relates to aerosol delivery devices and systems, such as smoking articles; and more particularly, holders for securing a detachable cartridge thereto. The smoking articles may be aerosol delivery devices and systems that utilize heat sources, such as combustible carbon-based ignition sources, for the production of aerosol (e.g., smoking articles for purposes of yielding components of tobacco, tobacco extracts, nicotine, synthetic nicotine, non-nicotine flavoring, and other materials in an inhalable form, commonly referred to as heat-not-burn systems or electronic cigarettes). Components of such articles can be made or derived from tobacco, or those articles can be characterized as otherwise incorporating tobacco for human consumption, and which are capable of vaporizing components of tobacco and/or other tobacco related materials to form an inhalable aerosol for human consumption.
Many smoking articles have been proposed through the years as improvements upon, or alternatives to, smoking products based upon combusting tobacco. Example alternatives have included devices wherein a solid or liquid fuel is combusted to transfer heat to tobacco or wherein a chemical reaction is used to provide such heat source. Examples include the smoking articles described in U.S. Pat. No. 9,078,473 to Worm et al., which is incorporated herein by reference.
The point of the improvements or alternatives to smoking articles typically has been to provide the sensations associated with cigarette, cigar, or pipe smoking, without delivering considerable quantities of incomplete combustion and pyrolysis products. To this end, there have been proposed numerous smoking products, flavor generators, and medicinal inhalers that utilize electrical energy to vaporize or heat a volatile material, or attempt to provide the sensations of cigarette, cigar, or pipe smoking without burning tobacco to a significant degree. See, for example, the various alternative smoking articles, aerosol delivery devices, and heat generating sources set forth in the background art described in U.S. Pat. No. 7,726,320 to Robinson et al.; and U.S. Patent Publication Nos. 2013/0255702 to Griffith, Jr. et al.; and 2014/0096781 to Sears et al., which are incorporated herein by reference. See also, for example, the various types of smoking articles, aerosol delivery devices and electrically powered heat generating sources referenced by brand name and commercial source in U.S. Patent Publication No. 2015/0220232 to Bless et al., which is incorporated herein by reference. Additional types of smoking articles, aerosol delivery devices and electrically powered heat generating sources referenced by brand name and commercial source are listed in U.S. Patent Publication No. 2015/0245659 to DePiano et al., which is also incorporated herein by reference in its entirety. Other representative cigarettes or smoking articles that have been described and, in some instances, been made commercially available include those described in U.S. Pat. No. 6,735,217 to Gerth et al.; U.S. Pat. Nos. 6,922,901, 6,947,874, and 6,947,875 to Brooks et al.; U.S. Pat. No. 5,060,671 to Counts et al.; U.S. Pat. No. 5,249,586 to Morgan et al.; U.S. Pat. No. 5,388,594 to Counts et al.; U.S. Pat. No. 5,666,977 to Higgins et al.; U.S. Pat. No. 6,053,176 to Adams et al.; U.S. Pat. No. 6,164,287 to White; U.S. Pat. No. 6,196,218 to Voges; U.S. Pat. No. 6,810,883 to Felter et al.; U.S. Pat. No. 6,854,461 to Nichols; U.S. Pat. No. 7,832,410 to Hon; U.S. Pat. No. 7,513,253 to Kobayashi; U.S. Pat. No. 7,726,320 to Robinson et al.; U.S. Pat. No. 7,896,006 to Hamano; U.S. Pat. No. 6,772,756 to Shayan; U.S. Patent Publication No. 2009/0095311 to Hon; U.S. Patent Publication Nos. 2006/0196518, 2009/0126745, and 2009/0188490 to Hon; U.S. Patent Publication No. 2009/0272379 to Thorens et al.; U.S. Patent Publication Nos. 2009/0260641 and 2009/0260642 to Monsees et al.; U.S. Patent Publication Nos. 2008/0149118 and 2010/0024834 to Oglesby et al.; U.S. Patent Publication No. 2010/0307518 to Wang; and WO 2010/091593 to Hon, which are incorporated herein by reference.
Various manners and methods for assembling smoking articles that possess a plurality of sequentially arranged segmented components have been proposed. See, for example, the various types of assembly techniques and methodologies set forth in U.S. Pat. No. 5,469,871 to Barnes et al. and U.S. Pat. No. 7,647,932 to Crooks et al.; and U.S. Patent Publication Nos. 2010/0186757 to Crooks et al.; 2012/0042885 to Stone et al., and 2012/00673620 to Conner et al.; each of which is incorporated by reference herein in its entirety.
Certain types of cigarettes that employ carbonaceous fuel elements have been commercially marketed under the brand names “Premier,” “Eclipse” and “Revo” by R. J. Reynolds Tobacco Company. See, for example, those types of cigarettes described in Chemical and Biological Studies on New Cigarette Prototypes that Heat Instead of Burn Tobacco, R. J. Reynolds Tobacco Company Monograph (1988) and Inhalation Toxicology, 12:5, p. 1-58 (2000). Additionally, a similar type of cigarette has been marketed in Japan by Japan Tobacco Inc. under the brand name “Steam Hot One.”
In some instances, some smoking articles, particularly those that employ a traditional paper wrapping material, are also prone to scorching of the paper wrapping material overlying an ignitable fuel source, due to the high temperature attained by the fuel source in proximity to the paper wrapping material. This can reduce enjoyment of the smoking experience for some consumers and can mask or undesirably alter the flavors delivered to the consumer by the aerosol delivery components of the smoking articles. In further instances, traditional types of smoking articles can produce relatively significant levels of gasses, such as carbon monoxide and/or carbon dioxide, during use (e.g., as products of carbon combustion). In still further instances, traditional types of smoking articles may suffer from poor performance with respect to aerosolizing the aerosol forming component(s).
As such, it would be desirable to provide smoking articles that address one or more of the technical problems sometimes associated with traditional types of smoking articles. In particular, it would be desirable to provide a smoking article that is easy to use and that provides reusable components.
In various implementations, the present disclosure provides a holder of a smoking article comprising a receiving end and a mouth end opposite the receiving end. The holder defines a socket that is configured to receive a proximal section of a cartridge.

In the expanded configuration, the socket may be configured to have a diameter greater than the proximal section of the cartridge. The main body portion may include an inner barrel that defines the socket and includes an outer wall. The outer barrel may be slidably received about the outer wall. The outer barrel may include an inner wall that is configured to engage the outer wall of the inner barrel as the outer barrel slides towards the received position to compress the socket towards a compressed configuration in which the socket is configured to secure the proximal section of the cartridge therein. The main body portion may include a divider cavity disposed within the inner barrel. The divider cavity may separate the bore from the socket and define a passageway that interconnects the bore and the socket. In the retracted position of the holder, an outer surface of the outer barrel may be flush with an outer wall of the main body portion.
In some implementations, the holder may include a cap comprising the receiving end that is configured to releasably coupled the main body portion. The cap and main body portion may be configured to encapsulate a cartridge received within the socket.

The connector may include a nub that extends from an outer surface of the connector. The nub may define a gap with an outer wall of the main body portion. The cap may include a retainer that extends inward in the receiver. The retainer may be configured to be received within the gap to secure the cap to the main body portion. The cap may be configured to receive the connector in a first radial position and to rotate to a second radial position with the connector disposed within the receiver to position the retainer within the gap. The cap may comprise a cap wall defining an outer surface of the cap. The cap wall may be flush with the outer wall of the main body portion when the cap is secured to the main body portion. The distal wall of the cap may comprise a vent hole that is defined therethrough.
In certain implementations, the main body portion comprises an outer wall and a sleeve and defines a chamber and a slot. The chamber may be positioned between and in communication with the bore and the socket. The slot may extend through the outer wall and be in communication with the chamber. The sleeve may be slidably disposed within the chamber and include a slide that extends through the slot. The slide may be coupled to the sleeve to translate the sleeve within the chamber as the slide translates within the slot. The sleeve may include a shaft that extends towards the receiving end of the holder. The sleeve may have a loading position in which the shaft is disposed proximal of the socket and an ejecting position in which a portion of the shaft extends into the socket. The shaft may include a cleat at a distal end thereof. The cleat may be configured to directly engage a cartridge. The sleeve may be configured to eject a cartridge from within the socket. The sleeve may define a vapor passageway therethrough. The vapor passageway may interconnect the socket and the bore through the sleeve.
In some implementations, the holder includes a mouthpiece that defines a portion of a bore, a main body portion that defines a chamber, and a sleeve that is slidably disposed within the chamber. The sleeve may include fingers that extend towards the receiving end of the holder and define a socket therebetween. The finger may have an expanded configuration in which the socket is configured to accept a proximal section of a cartridge and a compressed configuration in which the fingers are configured to engage the proximal section of the cartridge to secure the cartridge to the holder.
In certain implementations, the sleeve has a loading position in which the fingers are in the expanded configuration and a lighting position proximal of the loading position in which the fingers are in the compressed configuration. In the loading position of the sleeve, the fingers may extends distally from the chamber and in the lighting position of the sleeve, the fingers may be are disposed at least partially within the chamber with a wall defining the chamber urging the fingers inward from the expanded configuration. The fingers may be configured to draw the cartridge proximally as the sleeve slides from the loading position to the lighting position. In the lighting position of the sleeve, the fingers may be configured to secure the cartridge to the holder with a heat source of the cartridge extending beyond a receiving end of the holder.
In particular implementations, the main body portion defines a slot that extends through an outer wall thereof and is in communication with the chamber. The slot may have a first leg, a second leg, and a transverse leg. The first and second legs may extend in a direction parallel to one another and parallel to a longitudinal axis of the holder. The first and second legs may be radially offset relative to one another about the outer wall of the main body portion. The second leg may be longitudinally offset proximal of the first leg. The transverse leg may extend in a direction about the outer wall that is perpendicular to the first and second legs to interconnect the first and second legs.
In some implementations, the holder includes a slide that extends through the slot and is coupled to the sleeve. The sleeve may be configured to slide and rotate within the chamber in cooperation with the slide. In the loading configuration of the holder, the slide may be at a distal end of the first leg and the sleeve may be in a distal loading position with the fingers in the expanded configuration. In the lighting configuration of the holder, the slide may be longitudinally aligned with a proximal end of the first leg or a distal end of the second leg and the sleeve may be in a lighting position proximal of the loading position with the finger in the compressed configuration. In a received configuration of the holder, the slide may be at a proximal end of the second leg and the sleeve may be in a received position proximal of the lighting position with the fingers in the compressed configuration. The sleeve may be rotated about the longitudinal axis of the holder between the loading and received positions thereof. In the lighting configuration, the slide may be positioned within the transverse leg.
In particular implementations, the mouthpiece is releasably coupled to the main body portion. The holder may have a snub configuration in which the mouthpiece is secured to a distal section of the main body portion. In the snub configuration, the mouthpiece may be configured to be disposed over a heat source of a cartridge secured within the socket.
In certain implementations, the main body portion includes an inner barrel that forms a distal section thereof. The holder may include an outer barrel that is rotatably disposed over the inner barrel. The main body portion may define a slot that extends through the inner barrel and is in communication with the chamber. The slot may extend in a direction parallel to a longitudinal axis of the holder. The outer barrel may define a longitudinal chase that extends therethrough and in a direction parallel to the longitudinal axis of the holder. The outer barrel may also define a transverse chase that extends therethrough from a proximal end of the longitudinal chase in a direction about the outer barrel perpendicular to the longitudinal chase. The holder may include a slide that is secured to the sleeve and extends through the slot and the longitudinal chase or the transverse chase.
In some implementations, in a loading configuration of the holder, the slide is positioned at a distal end of the slot and a distal end of the longitudinal chase with the sleeve in a distal position such that the fingers are in the expanded configuration. In the lighting configuration of the holder, the slide may be positioned at a proximal end of the slot and a proximal end of the longitudinal chase with the sleeve in a proximal position such that the fingers are in the compressed configuration. In the received configuration of the holder, the slide may be positioned at a proximal end of the slot and within the transverse chase radially spaced apart from the longitudinal chase with the sleeve in the proximal position such that the fingers are in the compressed configuration.
In particular implementations, the inner barrel includes an inner cover at a distal end thereof and the outer barrel includes an outer cover at a distal end thereof. One or more of the inner cover or the outer cover comprises the receiving end. The inner cover may enclose a radial portion of a channel that is configured to receive a cartridge therein and the outer cover may enclose a radial portion of the channel. In the lighting configuration of the holder, the inner cover may be nested within the outer cover such that a radial portion of the channel is enclosed by the inner and outer covers and a radial portion of the channel opposite the inner and outer covers is open. In the received configuration of the holder, the inner and outer covers may oppose one another to radially enclose the channel. In the lighting and received configuration of the holder, the outer wall of the outer barrel may be flush within an outer wall of the main body portion.
In some implementations, the main body portion includes an inner barrel and a fixed cover. The inner barrel may define a distal portion of a channel that is positioned distal of the chamber. The fixed cover may extend distally from the inner barrel and enclose a radial portion of the channel. The channel may be configured to receive a cartridge therein. The fixed cover may radially enclose between 45 degrees and 315 degrees of the channel. The holder may include a movable cover that is opposed to the fixed cover. One or more of the fixed cover or the movable cover comprises the receiving end. The movable cover may enclose a radial portion of the channel. The movable cover may have an extend position in which the movable cover and the fixed cover radially enclose the channel therebetween. The movable cover may have a retracted position proximal of the extended position in which a portion of the channel is opposite the fixed cover and beyond a distal end of the movable cover is open. The holder may include a slide mechanism that is configured to translate the movable cover between the retracted and extended positions.
In particular implementations, in a loading configuration of the holder, the sleeve is in a loading position with the fingers in the expanded configuration and the movable cover is in the retracted position. In the lighting configuration of the holder, the sleeve may be in a lighting position proximal of the loading position with the fingers in the compressed configuration and the movable cover in the retracted position. In the received configuration of the holder, the sleeve may be in a received position proximal of the lighting position with the fingers in the compressed configuration and the movable cover in the extended position. The sleeve may engage the slide mechanism between the lighting position and the received position to transition the movable cover between the retracted position and the extended position. The slide mechanism may be configured to bias the movable cover to the retracted position when the movable cover is between the retracted position and the extended position and to maintain the movable cover in the extended position.
These and other features, aspects, and advantages of the disclosure will be apparent from a reading of the following detailed description together with the accompanying drawings, which are briefly described below.
Having thus described the disclosure in the foregoing general terms, reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
The present disclosure will now be described more fully hereinafter with reference to example implementations thereof. These example implementations are described so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Indeed, the disclosure is embodied in many different forms and should not be construed as limited to the implementations set forth herein; rather, these implementations are provided so that this disclosure will satisfy applicable legal requirements. As used in the disclosure, and in the appended claims, the singular forms “a”, “an”, “the”, include plural referents unless the context clearly dictates otherwise. As used in the disclosure, and in the appended claims, the term “proximal” refers to the portion of the device or component thereof that is closer to a user and the term “distal” refers to the portion of the device or component thereof that is farther from the user. Also, while reference may be made herein to quantitative measures, values, geometric relationships or the like, unless otherwise stated, any one or more if not all of these may be absolute or approximate to account for acceptable variations that may occur, such as those due to engineering tolerances or the like.
The present disclosure provides descriptions of articles (and the assembly and/or manufacture thereof) in which a material is heated (preferably without combusting the material to any significant degree) to form an aerosol and/or an inhalable substance; such articles may be sufficiently compact to be considered “hand-held” devices. In some aspects, the articles are characterized as smoking articles. As used herein, the term “smoking article” is intended to mean an article and/or device that provides many of the sensations (e.g., inhalation and exhalation rituals, types of tastes or flavors, organoleptic effects, physical feel, use rituals, visual cues such as those provided by visible aerosol, and the like) of smoking a cigarette, cigar, or pipe. As used herein, the term “smoking article” does not necessarily mean that, in operation, the article or device produces smoke in the sense of an aerosol resulting from by-products of combustion or pyrolysis of tobacco, but rather, that the article or device yields vapors (including vapors within aerosols that are considered to be visible aerosols that might be considered to be described as smoke-like) resulting from volatilization or vaporization of certain components, elements, and/or the like of the article and/or device. In certain aspects, articles or devices characterized as smoking articles incorporate tobacco and/or components derived from tobacco.
As noted, aerosol generating components of certain aerosol delivery devices may provide many of the sensations (e.g., inhalation and exhalation rituals, types of tastes or flavors, organoleptic effects, physical feel, use rituals, visual cues such as those provided by visible aerosol, and the like) of smoking a cigarette, cigar, or pipe that is employed by lighting and burning tobacco (and hence inhaling tobacco smoke), without any substantial degree of combustion of any component thereof. For example, the user of an aerosol delivery device in accordance with some example implementations of the present disclosure can hold and use that component much like a smoker employs a traditional type of smoking article, draw on one end of that piece for inhalation of aerosol produced by that piece, take, or draw puffs at selected intervals of time, and the like.
Articles or devices of the present disclosure are also characterized as being vapor-producing articles, aerosol delivery articles, or medicament delivery articles. Thus, such articles or devices are adaptable to provide one or more substances in an inhalable form or state. For example, inhalable substances are substantially in the form of a vapor (e.g., a substance that is in the gas phase at a temperature lower than its critical point). Alternatively, inhalable substances are in the form of an aerosol (e.g., a suspension of fine solid particles or liquid droplets in a gas). For purposes of simplicity, the term “aerosol” as used herein is meant to include vapors, gases, and aerosols of a form or type suitable for human inhalation, whether or not visible, and whether or not of a form that might be considered smoke-like. In some implementations, the terms “vapor” and “aerosol” may be interchangeable. Thus, for simplicity, the terms “vapor” and “aerosol” as used to describe the disclosure are understood to be interchangeable unless stated otherwise.
In use, smoking articles of the present disclosure are subjected to many of the physical actions of an individual in using a traditional type of smoking article (e.g., a cigarette, cigar, or pipe that is employed by lighting with a flame and used by inhaling tobacco that is subsequently burned and/or combusted). For example, the user of a smoking article of the present disclosure holds that article much like a traditional type of smoking article, draws on one end of that article for inhalation of an aerosol produced by that article, and takes puffs at selected intervals of time.
While the systems are generally described herein in terms of implementations associated with smoking articles such as so-called “tobacco heating products,” it should be understood that the mechanisms, components, features, and methods may be embodied in many different forms and associated with a variety of articles. For example, the description provided herein may be employed in conjunction with implementations of traditional smoking articles (e.g., cigarettes, cigars, pipes, etc.), heat-not-burn cigarettes, and related packaging for any of the products disclosed herein. Accordingly, it should be understood that the description of the mechanisms, components, features, and methods disclosed herein are discussed in terms of implementations relating to aerosol delivery devices by way of example only, and may be embodied and used in various other products and methods.
Smoking articles of the present disclosure generally include a number of elements provided or contained within an enclosure of some sort, such as a housing, an outer wrap, or wrapping, a casing, a component, a module, a member, or the like. The overall design of the enclosure is variable, and the format or configuration of the enclosure that defines the overall size and shape of the smoking article is also variable. It is desirable, in some aspects, that the overall design, size, and/or shape of the enclosure resembles that of a conventional cigarette or cigar. Typically, an enclosure resembling the shape of a cigarette or cigar comprises separable components, members, or the like that are engaged to form the enclosure. For example, such a smoking article may comprise, in some aspects, three separable components that include a mouthpiece component, an aerosol delivery component (such as, for example, a substrate material), and a heat source component. In various aspects, the heat source may be capable of generating heat to aerosolize a substrate material that comprises, for example, an extruded structure and/or substrate, a substrate material associated with an aerosol precursor composition, tobacco and/or a tobacco related material, such as a material that is found naturally in tobacco that is isolated directly from the tobacco or synthetically prepared, in a solid or liquid form (e.g., beads, sheets, shreds, a wrap), or the like. In some implementations, an extruded structure may comprise tobacco products or a composite of tobacco with other materials such as, for example, ceramic powder. In other implementations, a tobacco extract/slurry may be loaded into porous ceramic beads. Other implementations may use non-tobacco products. In some implementations, aerosol precursor composition-loaded porous beads/powders (ceramics) may be used. In other implementations, rods/cylinders made of extruded slurry of ceramic powder and aerosol precursor composition may be used.
According to certain aspects of the present disclosure, it may be advantageous to provide a smoking article that is easy to use and that provides reusable components.
It should be noted that although in the depicted implementation the cartridge 50 and the holder 104 have substantially cylindrical shapes that imitate the shape of a traditional cigarette, in various other implementations, any one or both of these components (and/or any of their subcomponents, such as, for example, the main body portion 110 or the mouthpiece 112, and/or the heat source 54, the outer housing 53, or the substrate material 51 of the cartridge 50) may have a different shape. For example, in some implementations one or both of the holder 104 or the cartridge 50 (and/or any of their subcomponents) may have a substantially rectangular shape, such as a substantially rectangular cuboid shape. In other implementations, one or both of the holder 104 or the cartridge 50 (and/or any of their subcomponents) may have other hand-held shapes. For example, in some implementations, the holder 104 may have a small box shape, various pod mod shapes, or a fob-shape.
In various implementations, the heat source 54 may be configured to generate heat upon ignition thereof. In the depicted implementation, the heat source 54 comprises a combustible fuel element that has a generally cylindrical shape and that incorporates a combustible carbonaceous material. In other implementations, the heat source 54 may have a different shape, for example, a prism shape having a cubic or hexagonal cross-section. Carbonaceous materials generally have a high carbon content. Preferred carbonaceous materials are composed predominately of carbon, and/or typically have carbon contents of greater than 60 percent, generally greater than 70 percent, often greater than 80 percent, and frequently greater than 90 percent, on a dry weight basis.
In some instances, the heat source 54 may incorporate elements other than combustible carbonaceous materials (e.g., tobacco components, such as powdered tobaccos or tobacco extracts; flavoring agents; salts, such as sodium chloride, potassium chloride and sodium carbonate; heat stable graphite a hollow cylindrical (e.g., tube) fibers; iron oxide powder; glass filaments; powdered calcium carbonate; alumina granules; ammonia sources, such as ammonia salts; and/or binding agents, such as guar gum, ammonium alginate and sodium alginate). In other implementations, the heat source may comprise a plurality of ignitable objects, such as, for example, a plurality of ignitable beads. It should be noted that in other implementations, the heat source may differ in composition or relative content amounts from those listed above. For example, in some implementations different forms of carbon could be used as a heat source, such as graphite or graphene. In other implementations, the heat source may have increased levels of activated carbon, different porosities of carbon, different amounts of carbon, blends of any above mentioned components, etc. In still other implementations, the heat source may comprise a non-carbon heat source, such as, for example, a combustible liquefied gas configured to generate heat upon ignition thereof. For example, in some implementations, the liquefied gas may comprise one or more of petroleum gas (LPG or LP-gas), propane, propylene, butylenes, butane, isobutene, methyl propane, or n-butane. In still other implementations, the heat source may comprise a chemical reaction based heat source, wherein ignition of the heat source comprises the interaction of two or more individual components. For example, a chemical reaction based heat source may comprise metallic agents and an activating solution, wherein the heat source is activated when the metallic agents and the activating solution come in contact. Some examples of chemical based heat sources can be found in U.S. Pat. No. 7,290,549 to Banerjee et al., which is incorporated herein by reference in its entirety. Combinations of heat sources are also possible.
Although specific dimensions of an applicable heat source may vary, in the depicted implementation, the heat source 54 has a length in an inclusive range of 5 mm to 20 mm, and in some implementations may be 17 mm, and an overall diameter in an inclusive range of 3 mm to 8 mm, and in some implementations may be 6.8 mm (and in some implementations, 7 mm). Although in other implementations, the heat source may be constructed in a variety of ways, in the depicted implementation, the heat source 54 is extruded or compounded using a ground or powdered carbonaceous material, and has a density that is greater than 0.5 g/cm3, often greater than 0.7 g/cm3, and frequently greater than 1 g/cm3, on a dry weight basis. See, for example, the types of fuel source components, formulations and designs set forth in U.S. Pat. No. 5,551,451 to Riggs et al. and U.S. Pat. No. 7,836,897 to Borschke et al., which are incorporated herein by reference in their entireties.
Although in various implementations the heat source 54 may have a variety of forms, including, for example, a substantially solid cylindrical shape or a hollow cylindrical (e.g., tube) shape, the heat source 54 of the depicted implementation comprises an extruded monolithic carbonaceous material that has a generally cylindrical shape that includes a plurality of internal passages 55 extending longitudinally from a first end of the heat source 54 to an opposing second end of the heat source 54. In the depicted implementation there are thirteen internal passages 55 comprising a single central internal passage 55a, six surrounding internal passages 55b, which are spaced from the central internal passages 55a and have a similar size (e.g., diameter) to that of the central internal passage 55a, and six peripheral internal passages 55c, which are spaced from an outer surface of the heat source 54 and are smaller in diameter than that of the central internal passage 55a. It should be noted that in other implementations, there need not be a plurality of internal passages and/or the plurality of internal passages may take other forms and/or sizes. For example, in some implementations, there may be as few as two internal passages, and still other implementations may include a single internal passage. Still other implementations may include no internal passages at all. Additional implementations may include multiple internal passages that may be of unequal diameter and/or shape and which may be unequally spaced and/or located within the heat source.
Although not depicted in the figures, some implementations may include one or more peripheral grooves that extend longitudinally from a first end of the heat source to an opposing second end. In some implementations, such grooves may be substantially equal in width and depth and may be substantially equally distributed about a circumference of the heat source. In such implementations, there may be as few as two grooves, and still other implementations may include a single groove. Still other implementations may include no grooves at all. Additional implementations may include multiple grooves that may be of unequal width and/or depth, and which may be unequally spaced around a circumference of the heat source. In still other implementations, the heat source may include flutes and/or slits extending longitudinally from a first end of the extruded monolithic carbonaceous material to an opposing second end thereof. In some implementations, the heat source may comprise a foamed carbon monolith formed in a foam process of the type disclosed in U.S. Pat. No. 7,615,184 to Lobovsky, which is incorporated herein by reference in its entirety. As such, some implementations may provide advantages with regard to reduced time taken to ignite the heat source. In some other implementations, the heat source may be co-extruded with a layer of insulation (not shown), thereby reducing manufacturing time and expense. Other implementations of fuel elements include carbon fibers of the type described in U.S. Pat. No. 6,922,901 to Brooks et al. or other heat source implementations such as is disclosed in U.S. Patent Publication No. 2009/0044818 to Takeuchi et al., 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 that include such heat sources are disclosed in U.S. patent application Ser. No. 15/902,665, filed on Feb. 22, 2018, and titled 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.
Generally, the heat source is positioned sufficiently near an aerosol delivery component (e.g., the substrate portion) 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 flavorants, medicaments, and/or the like that are likewise provided for delivery to a user) is deliverable to the user by way of the mouthpiece. That is, when the heat source heats the substrate component, an aerosol is formed, released, or generated in a physical form suitable for inhalation by a consumer. It should be noted that the foregoing terms are meant to be interchangeable such that reference to release, releasing, releases, or released includes form or generate, forming or generating, forms or generates, and formed or generated. Specifically, an inhalable substance is released in the form of a vapor or aerosol or mixture thereof. Additionally, the selection of various smoking article elements are appreciated upon consideration of commercially available electronic smoking articles, such as those representative products listed in the background art section of the present disclosure.
In the depicted implementation, the substrate portion 52 comprises a substrate material 51 having a single segment, although in other implementations the substrate portion 52 may include one or more additional substrate material segments. For example in some implementations, the smoking article 100 may further comprise a second substrate material segment (not shown) having opposed first and second ends. In various implementations, one or more of the substrate materials may include a tobacco or tobacco related material, with an aerosol precursor composition associated therewith. In other implementations, non-tobacco materials may be used, such as a cellulose pulp material. In other implementations, the non-tobacco substrate material may not be a plant-derived material. Other possible compositions, components, and/or additives for use in a substrate material (and/or substrate materials) are described in more detail below. It should be noted that the subsequent discussion should be applicable any substrate material usable in the smoking articles described herein (such as, for example, the substrate material 51 of the depicted implementation).

In particular implementations, the substrate material 51 may comprise a blend of flavorful and aromatic tobaccos in cut filler form. In some implementations, the substrate material 51 may comprise a reconstituted tobacco material, such as described in U.S. Pat. No. 6,807,809 to Pryor et al.; U.S. Pat. No. 6,889,143 to Pryor et al. and U.S. Pat. No. 5,025,814 to Raker, the disclosures of which are incorporated herein by reference in their entirety. Additionally, a reconstituted tobacco material may include a reconstituted tobacco paper for the type of cigarettes described in Chemical and Biological Studies on New Cigarette Prototypes that Heat Instead of Burn Tobacco, R. J. Reynolds Tobacco Company Monograph (1988), the contents of which are incorporated herein by reference in its entirety. For example, a reconstituted tobacco material may include a sheet-like material containing tobacco and/or tobacco-related materials. As such, in some implementations, the substrate material may be formed from a wound roll of a reconstituted tobacco material. In certain implementations, the substrate material may be formed from shreds, strips, and/or the like of a reconstituted tobacco material. In another implementation, the tobacco sheet may comprise overlapping layers (e.g., a gathered web), which may, or may not, include heat conducting constituents. Examples of substrate portions that include a series of overlapping layers (e.g., gathered webs) of an initial substrate sheet formed by the fibrous filler material, aerosol forming material, and plurality of heat conducting constituents are described in U.S. patent application Ser. No. 15/905,320, filed on Feb. 26, 2018, and titled Heat Conducting Substrate For Electrically Heated Aerosol Delivery Device, which is incorporated herein by reference in its entirety.
In some implementations, the substrate material 51 may include a plurality of microcapsules, beads, granules, and/or the like having a tobacco-related material. For example, a representative microcapsule may be generally spherical in shape, and may have an outer cover or shell that contains a liquid center region of a tobacco-derived extract and/or the like. In some implementations, one or more of the substrate materials may include a plurality of microcapsules each formed into a hollow cylindrical shape. In some implementations, one or more of the substrate materials may include a binder material configured to maintain the structural shape and/or integrity of the plurality of microcapsules formed into the hollow cylindrical shape.
Tobacco employed in one or more of the substrate materials may include, or may be derived from, tobaccos such as flue-cured tobacco, burley tobacco, Oriental tobacco, Maryland tobacco, dark tobacco, dark-fired tobacco and Rustica tobacco, as well as other rare or specialty tobaccos, or blends thereof. Various representative tobacco types, processed types of tobaccos, and types of tobacco blends are set forth in U.S. Pat. No. 6,836,224 to Lawson et al.; U.S. Pat. No. 6,924,888 to Perfetti et al.; U.S. Pat. No. 5,056,537 to Brown et al.; U.S. Pat. No. 5,159,942 to Brinkley et al.; U.S. Pat. No. 5,220,930 to Gentry; U.S. Pat. No. 5,360,023 to Blakley et al.; U.S. Pat. No. 6,701,936 to Shafer et al.; U.S. Pat. No. 6,730,832 to Dominguez et al.; U.S. Pat. No. 7,011,096 to Li et al.; U.S. Pat. No. 7,017,585 to Li et al.; U.S. Pat. No. 7,025,066 to Lawson et al.; U.S. Patent Publication No. 2004/0255965 to Perfetti et al.; PCT Publication No. WO 02/37990 to Bereman; and Bombick et al., Fund. Appl. Toxicol., 39, p. 11-17 (1997); the disclosures of which are incorporated herein by reference in their entireties.
In some implementations of the present disclosure, the substrate material 51 may include an extruded structure that includes, or is essentially comprised of a tobacco, a tobacco related material, glycerin, water, and/or a binder material, although certain formulations may exclude the binder material. In various implementations, suitable binder materials may include alginates, such as ammonium alginate, propylene glycol alginate, potassium alginate, and sodium alginate. Alginates, and particularly high viscosity alginates, may be employed in conjunction with controlled levels of free calcium ions. Other suitable binder materials include hydroxypropylcellulose such as Klucel H from Aqualon Co.; hydroxypropylmethylcellulose such as Methocel K4MS from The Dow Chemical Co.; hydroxyethylcellulose such as Natrosol 250 MRCS from Aqualon Co.; microcrystalline cellulose such as Avicel from FMC; methylcellulose such as Methocel A4M from The Dow Chemical Co.; and sodium carboxymethyl cellulose such as CMC 7HF and CMC 7H4F from Hercules Inc. Still other possible binder materials include starches (e.g., cornstarch), guar gum, carrageenan, locust bean gum, pectins, and xanthan gum. In some implementations, combinations or blends of two or more binder materials may be employed. Other examples of binder materials are described, for example, in U.S. Pat. No. 5,101,839 to Jakob et al.; and U.S. Pat. No. 6,924,887 to Raker et al., each of which is incorporated herein by reference in its entirety. In some implementations, the aerosol forming material may be provided as a portion of the binder material (e.g., propylene glycol alginate). In addition, in some implementations, the binder material may comprise nanocellulose derived from a tobacco or other biomass.
In some implementations, the substrate material 51 may include an extruded material, as described in U.S. Patent Publication No. 2012/0042885 to Stone et al., which is incorporated herein by reference in its entirety. In yet another implementation, the substrate material may include an extruded structure and/or substrate formed from marumarized and/or non-marumarized tobacco. Marumarized tobacco is known, for example, from U.S. Pat. No. 5,105,831 to Banerjee, et al., which is incorporated by reference herein in its entirety. Marumarized tobacco includes 20 to 50 percent (by weight) tobacco blend in powder form, with glycerol (at 20 to 30 percent weight), calcium carbonate (generally at 10 to 60 percent by weight, often at 60 to 60 percent by weight), along with binder agents, as described herein, and/or flavoring agents. In various implementations, the extruded material may have one or more longitudinal openings.
In various implementations, the substrate material 51 may take on a variety of conformations based upon the various amounts of materials utilized therein. For example, a sample substrate material may comprise up to 98% by weight, up to 95% by weight, or up to 90% by weight of a tobacco and/or tobacco related material. A sample substrate material may also comprise up to 25% by weight, 20% by weight, or 15% by weight water—particularly 2% to 25%, 5% to 20%, or 7% to 15% by weight water. Flavors and the like (which include, for example, medicaments, such as nicotine) may comprise up to 10%, up to 8%, or up to 5% by weight of the aerosol delivery component.
Additionally or alternatively, the substrate material 51 may include an extruded structure and/or a substrate that includes or essentially is comprised of tobacco, glycerin, water, and/or binder material, and is further configured to substantially maintain its structure throughout the aerosol-generating process. That is, the substrate material may be configured to substantially maintain its shape (e.g., the substrate material does not continually deform under an applied shear stress) throughout the aerosol-generating process. Although such an example substrate material may include liquids and/or some moisture content, the substrate may remain substantially solid throughout the aerosol-generating process and may substantially maintain structural integrity throughout the aerosol-generating process. Example tobacco and/or tobacco related materials suitable for a substantially solid substrate material are described in U.S. Patent Publication No. 2015/0157052 to Ademe et al.; U.S. Patent Publication No. 2015/0335070 to Sears et al.; U.S. Pat. No. 6,204,287 to White; and U.S. Pat. No. 5,060,676 to Hearn et al., which are incorporated herein by reference in their entirety.
In some implementations, the amount of substrate material 51 that is used within the smoking article may be such that the article exhibits acceptable sensory and organoleptic properties, and desirable performance characteristics. For example, in some implementations an aerosol precursor composition such as, for example, glycerin and/or propylene glycol, may be employed within the substrate material in order to provide for the generation of a visible mainstream aerosol that in many regards resembles the appearance of tobacco smoke. For example, the amount of aerosol precursor composition incorporated into the substrate material of the smoking article may be in the range of 3.5 grams or less, 3 grams or less, 2.5 grams or less, 2 grams or less, 1.5 grams or less, 1 gram or less, or 0.5 gram or less.
According to some implementations, a smoking article according to the present disclosure may include a substrate material 51 comprising a porous, inert material such as, for example, a ceramic material. For example, in some implementations ceramics of various shapes and geometries (e.g., beads, rods, tubes, etc.) may be used, which have various pore morphology. In addition, in some implementations non-tobacco materials, such as an aerosol precursor composition, may be loaded into the ceramics. In another implementation, the substrate material may include a porous, inert material that does not substantially react, chemically and/or physically, with a tobacco-related material such as, for example, a tobacco-derived extract. In addition, an extruded tobacco, such as those described above, may be porous. For example, in some implementations an extruded tobacco material may have an inert gas, such as, for example, nitrogen, that acts as a blowing agent during the extrusion process.
As noted above, in various implementations one or more of the substrate materials may include a tobacco, a tobacco component, and/or a tobacco-derived material that has been treated, manufactured, produced, and/or processed to incorporate an aerosol precursor composition (e.g., humectants such as, for example, propylene glycol, glycerin, and/or the like) and/or at least one flavoring agent, as well as a flame/burn retardant (e.g., diammonium phosphate and/or another salt) configured to help prevent ignition, pyrolysis, combustion, and/or scorching of the substrate material by the heat source. Various manners and methods for incorporating tobacco into smoking articles, and particularly smoking articles that are designed so as to not purposefully burn virtually all of the tobacco within those smoking articles are set forth in U.S. Pat. No. 6,947,874 to Brooks et al.; U.S. Pat. No. 7,647,932 to Cantrell et al.; U.S. Pat. No. 8,079,371 to Robinson et al.; U.S. Pat. No. 7,290,549 to Banerjee et al.; and U.S. Patent Publication No. 2007/0215167 to Crooks et al.; the disclosures of which are incorporated herein by reference in their entireties.
As noted, in some implementations, flame/burn retardant materials and other additives that may be included within one or more of the substrate materials and may include organo-phosophorus compounds, borax, hydrated alumina, graphite, potassium tripolyphosphate, dipentaerythritol, pentaerythritol, and polyols. Others such as nitrogenous phosphonic acid salts, mono-ammonium phosphate, ammonium polyphosphate, ammonium bromide, ammonium borate, ethanolammonium borate, ammonium sulphamate, halogenated organic compounds, thiourea, and antimony oxides are suitable agents. In each aspect of flame-retardant, burn-retardant, and/or scorch-retardant materials used in the substrate material and/or other components (whether alone or in combination with each other and/or other materials), the desirable properties most preferably are provided without undesirable off-gassing or melting-type behavior.
According to other implementations of the present disclosure, the substrate material 51 may also incorporate tobacco additives of the type that are traditionally used for the manufacture of tobacco products. Those additives may include the types of materials used to enhance the flavor and aroma of tobaccos used for the production of cigars, cigarettes, pipes, and the like. For example, those additives may include various cigarette casing and/or top dressing components. See, for example, U.S. Pat. No. 3,419,015 to Wochnowski; U.S. Pat. No. 6,054,145 to Berndt et al.; U.S. Pat. No. 6,887,619 to Burcham, Jr. et al.; U.S. Pat. No. 5,022,416 to Watson; U.S. Pat. No. 5,103,842 to Strang et al.; and U.S. Pat. No. 5,711,320 to Martin; the disclosures of which are incorporated herein by reference in their entireties. 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 flavoring agents (e.g., cocoa and licorice). Those added components may also include top dressing materials (e.g., flavoring materials, such as menthol). See, for example, U.S. Pat. No. 6,449,541 to Mays et al., the disclosure of which is incorporated herein by reference in its entirety. Further materials that may be added include those disclosed in U.S. Pat. No. 6,830,028 to Lawson et al. and U.S. Pat. No. 8,186,360 to Marshall et al., the disclosures of which are incorporated herein by reference in their entireties.
In some implementations, the substrate material may comprise a liquid including an aerosol precursor composition and/or a gel including an aerosol precursor composition. Some examples of liquid compositions can be found in U.S. patent application Ser. No. 16/171,920, filed on Oct. 26, 2018, and titled Aerosol Delivery Device with Visible Indicator, which is incorporated herein by reference in its entirety.
As noted above, in various implementations, one or more of the substrate materials may have an aerosol precursor composition associated therewith. For example, in some implementations the aerosol precursor composition may comprise one or more different components, such as polyhydric alcohol (e.g., glycerin, propylene glycol, or a mixture thereof). Representative types of further aerosol precursor compositions are set forth in U.S. Pat. No. 6,793,365 to Sensabaugh, Jr. et al.; U.S. Pat. No. 5,101,839 to Jakob et al.; PCT WO 98/57556 to Biggs et al.; and Chemical and Biological Studies on New Cigarette Prototypes that Heat Instead of Burn Tobacco, R. J. Reynolds Tobacco Company Monograph (1988); the disclosures of which are incorporated herein by reference. In some aspects, a substrate material may produce a visible aerosol upon the application of sufficient heat thereto (and cooling with air, if necessary), and the substrate material may produce an aerosol that is “smoke-like.” In other aspects, the substrate material may produce an aerosol that is substantially non-visible but is recognized as present by other characteristics, such as flavor or texture. Thus, the nature of the produced aerosol may be variable depending upon the specific components of the aerosol delivery component. The substrate material may be chemically simple relative to the chemical nature of the smoke produced by burning tobacco.
In some implementations, the aerosol precursor composition may incorporate nicotine, which may be present in various concentrations. The source of nicotine may vary, and the nicotine incorporated in the aerosol precursor composition may derive from a single source or a combination of two or more sources. For example, in some implementations the aerosol precursor composition may include nicotine derived from tobacco. In other implementations, the aerosol precursor composition may include nicotine derived from other organic plant sources, such as, for example, non-tobacco plant sources including plants in the Solanaceae family. In other implementations, the aerosol precursor composition may include synthetic nicotine. In some implementations, nicotine incorporated in the aerosol precursor composition may be derived from non-tobacco plant sources, such as other members of the Solanaceae family. The aerosol precursor composition may additionally or alternatively include other active ingredients including, but not limited to, botanical ingredients (e.g., lavender, peppermint, chamomile, basil, rosemary, thyme, eucalyptus, ginger, cannabis, ginseng, maca, and tisanes), stimulants (e.g., caffeine and guarana), amino acids (e.g., taurine, theanine, phenylalanine, tyrosine, and tryptophan) and/or pharmaceutical, nutraceutical, and medicinal ingredients (e.g., vitamins, such as B6, B12, and C and cannabinoids, such as tetrahydrocannabinol (THC) and cannabidiol (CBD)).
A wide variety of types of flavoring agents, or materials that alter the sensory or organoleptic character or nature of the mainstream aerosol of the smoking article may be suitable to be employed. In some implementations, such flavoring agents may be provided from sources other than tobacco and may be natural or artificial in nature. For example, some flavoring agents may be applied to, or incorporated within, the substrate material and/or those regions of the smoking article where an aerosol is generated. In some implementations, such agents may be supplied directly to a heating cavity or region proximate to the heat source or are provided with the substrate material. Example flavoring agents may include, for example, vanillin, ethyl vanillin, cream, tea, coffee, fruit (e.g., apple, cherry, strawberry, peach and citrus flavors, including lime and lemon), maple, menthol, mint, peppermint, spearmint, wintergreen, nutmeg, clove, lavender, cardamom, ginger, honey, anise, sage, cinnamon, sandalwood, jasmine, cascarilla, cocoa, licorice, and flavorings and flavor packages of the type and character traditionally used for the flavoring of cigarette, cigar, and pipe tobaccos. Syrups, such as high fructose corn syrup, may also be suitable to be employed.
Flavoring agents may also include acidic or basic characteristics (e.g., organic acids, such as levulinic acid, succinic acid, pyruvic acid, and benzoic acid). In some implementations, flavoring agents may be combinable with the elements of the substrate material if desired. Example plant-derived compositions that may be suitable are disclosed in U.S. Pat. No. 9,107,453 and U.S. Patent Publication No. 2012/0152265 both to Dube et al., the disclosures of which are incorporated herein by reference in their entireties. Any of the materials, such as flavorings, casings, and the like that may be useful in combination with a tobacco material to affect sensory properties thereof, including organoleptic properties, such as described herein, may be combined with the substrate material. Organic acids particularly may be able to be incorporated into the substrate material to affect the flavor, sensation, or organoleptic properties of medicaments, such as nicotine, that may be able to be combined with the substrate material. For example, organic acids, such as levulinic acid, lactic acid, pyruvic acid, and benzoic acid may be included in the substrate material with nicotine in amounts up to being equimolar (based on total organic acid content) with the nicotine. Any combination of organic acids may be suitable. For example, in some implementations, the substrate material may include 0.1 to 0.5 moles of levulinic acid per one mole of nicotine, 0.1 to 0.5 moles of pyruvic acid per one mole of nicotine, 0.1 to 0.5 moles of lactic acid per one mole of nicotine, or combinations thereof, up to a concentration wherein the total amount of organic acid present is equimolar to the total amount of nicotine present in the substrate material. Various additional examples of organic acids employed to produce a substrate material are described in U.S. Patent Publication No. 2015/0344456 to Dull et al., which is incorporated herein by reference in its entirety. The selection of such further components may be variable based upon factors such as the sensory characteristics that are desired for the smoking article, and the present 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 disclosures of which are incorporated herein by reference in their entireties.
In other implementations, the substrate material 51 may include other materials having a variety of inherent characteristics or properties. For example, the substrate material may include a plasticized material or regenerated cellulose in the form of rayon. As another example, viscose (commercially available as VISIL®), which is a regenerated cellulose product incorporating silica, may be suitable. Some carbon fibers may include at least 95 percent carbon or more. Similarly, natural cellulose fibers such as cotton may be suitable, and may be infused or otherwise treated with silica, carbon, or metallic particles to enhance flame-retardant properties and minimize off gassing, particularly of any undesirable off-gassing components that would have a negative impact on flavor (and especially minimizing the likelihood of any toxic off-gassing products). Cotton may be treatable with, for example, boric acid or various organophosphate compounds to provide desirable flame-retardant properties by dipping, spraying, or other techniques known in the art. These fibers may also be treatable (coated, infused, or both by, e.g., dipping, spraying, or vapor-deposition) with organic or metallic nanoparticles to confer the desired property of flame-retardancy without undesirable off-gassing or melting-type behavior.
Continuing to refer to
As shown in
In the depicted implementation, the outer housing 53 is constructed as tube structure that encapsulates the substrate material 51; however, as noted above, in other implementations the outer housing 53 may have other shapes. Although the shape of the outer housing 53 may vary, in the depicted implementation the outer housing 53 comprises a tube structure having an open end and a closed end. The depicted implementation of the outer housing 53 also includes one or more end aperture 56 located on the closed end of the outer housing 53 that are configured to allow aerosolized vapor (herein alternatively referred to as a “vapor” or “aerosol”) to pass therethrough. The end apertures 56 of the depicted implementation are in the form of a pair of elongate rounded slots; however, in other implementations the end aperture 56 may have any form that permits passage of the aerosol therethrough. As such, it will be appreciated that the end apertures 318 can comprise fewer or additional apertures and/or alternative shapes and sizes of apertures than those illustrated.
Referring briefly back to
In various implementations, the main body portion 104 may be constructed of a metal material (such as, for example, stainless steel, aluminum, brass, copper, silver, gold, and bronze), or a graphite material, or a ceramic material, or a plastic material, or any combinations thereof. Other materials are also possible. The holder 104 of the depicted implementation may also include a plurality of end openings (not shown) that extend therethrough and are configured to align with at least a portion of the heat source 54 when the cartridge 50 is in the received configuration. In such a manner, the end openings are configured to provide the heat source 54 with sufficient airflow to keep the heat source 54 ignited when in the received configuration. While in various implementations, such openings may have many different configurations (including, for example, slots and/or rings instead of, or in addition to, holes), in the depicted implementation, the end openings comprise an alternating pattern of substantially circular holes that extend around a circumference of the receiving end of the holder 104. In particular, the alternating patterns of the depicted implementation include a first pattern of four longitudinally spaced holes repeated at 90° intervals around the circumference of the receiving end of the main body portion 110 of the holder 104, and a second pattern of three longitudinally spaced holes also repeated at 90° intervals, but shifted from the first pattern by 65° around the circumference of the end of the main body portion 110. For additional detail on suitable end openings, reference may be made to U.S. patent application Ser. No. 16/035,103 titled Smoking Article with Detachable Cartridge filed Jul. 13, 2018, the entire contents of which are hereby incorporated by reference.
The holder 104 includes the main body portion 110 and an outer barrel 128 that is slidable over a portion of the main body portion 110. The main body portion 110 includes the mouthpiece 112 and an inner barrel 128. The mouthpiece 112 and the inner barrel 128 define a chamber 116 about a central longitudinal axis of the of the main body portion 110. The inner barrel 128 also defines a portion of the channel 118 about the central longitudinal axis of the main body 110. The chamber 116 and the channel 118 may be separated by a divider cavity 120 that is positioned within the inner barrel 128. In other implementations, the divider cavity may be replaced with a divider component, which may include one or more vapor passages disposed therethrough to allow air and/or aerosol to flow between the channel 118 and the chamber 116. The bore 114 may include one or more filters 115 disposed therein. As shown, four filters 115 are serially disposed with one another within the bore 114. The filters 115 may be permanent or replaceable. For example, the mouthpiece 112 may be separable from the inner barrel 128, e.g., by unscrewing the mouthpiece 112 from the inner barrel 128, such that the chamber 124 is opened and the filters 115 can be replaced. In some implementations, the mouthpiece 112 and the inner barrel 128 are inseparable from one another. In certain implementations, the mouthpiece 112 and the inner barrel 128 are integrally formed with one another. In various implementations, the filters 115 may comprise a packed rod or cylindrical disc constructed of a gas permeable material (such as, for example, cellulose acetate or polylactic acid (PLA), polyvinyl alcohol (PVOH), or polypropylene fibers such as paper or rayon, or polyester fibers, or various combinations thereof). The filters 115 may additionally or alternatively contain strands of tobacco containing material, such as described in U.S. Pat. No. 5,025,814 to Raker et al., which is incorporated herein by reference in its entirety. In various implementations, the size and shape of the filter may vary.
In some implementations, the smoking article 100 may also include an intermediate component between the cartridge 50 and the filter 115. It should be noted that in various implementations, the intermediate component or the filter, individually or together, may be considered a filter of the smoking article. In various implementations, neither the intermediate component nor the filter need be included. In some implementations, the intermediate component may comprise a substantially rigid member that is substantially inflexible along its longitudinal axis. In some implementations, the intermediate component may comprise a hollow tube structure and may be included to provide for cooling the produced aerosol. In some implementations, the intermediate component may be used as a container for collecting the aerosol. In various implementations, such a tube may be constructed from any of a variety of materials and may include one or more adhesives. Example materials include, but are not limited to, paper, paper layers, paperboard, plastic, cardboard, and/or composite materials. In some implementations, the intermediate component may comprise a hollow cylindrical element constructed of a paper or plastic material (such as, for example, ethyl vinyl acetate (EVA), or other polymeric materials such as poly ethylene, polyester, silicone, etc. or ceramics (e.g., silicon carbide, alumina, etc.), or other acetate fibers), and the filter comprises a packed rod or cylindrical disc constructed of a gas permeable material (such as, for example, cellulose acetate or fibers such as paper or rayon, or polyester fibers).
The inner barrel 128 includes an outer wall 129 having a diameter slightly less than the mouthpiece 112 such that a stop 126 is defined between the mouthpiece 112 and the outer wall 129. The mouthpiece 112 may include a step adjacent the stop 126 such that the stop 126 is slightly larger than the remainder of the mouthpiece 112. For example, the mouthpiece 112 may have a diameter of 9.9 mm and the outer wall 129 of the inner barrel 128 may have a diameter of 8 mm. In addition, the stop 126 may have a diameter of 10 mm. The difference between the diameter of inner barrel 128 and the stop 126 may be referred to as a recess 127 about the outer wall 129 of the inner barrel 128. In some implementations, the outer wall 129 is tapered outward from the stop 126 towards the receiving end of the holder 104.
The outer barrel 140 is slidably received over the inner barrel 128 and has a proximal section 142 and a distal section 148 with proximal being defined as closer to a mouth end 113 of the holder 104 and distal being closer to the receiving end of the holder 104. The outer barrel 140 includes an inner wall 141 that defines the channel 118. The inner wall 141 is disposed about the inner barrel 128 such that the inner barrel 128 is at least partially received within the channel 118. The inner wall 141 has a diameter substantially equal to or slightly less than the outer diameter of the inner barrel 128 such that the outer barrel 140 may slightly compress the inner barrel 128 inward as described in greater detail below. In the depicted implementation, the outer barrel 140 defines relief slits 149 in the distal section 136 thereof that allow the distal section 136 to expand as the outer barrel 140 approaches the load configuration. In some implementations, the inner wall 141 of the outer barrel 140 is tapered inward from a distal end towards a proximal end thereof. In particular implements, the tapers of the inner wall 141 of the outer barrel 140 and the outer wall 129 of the inner barrel 128 cooperate to compress the inner barrel 128 inward as the outer barrel 140 is translated distally.

With the proximal section 59 of the cartridge 50 adjacent to or in abutment with the divider cavity 120, the outer barrel 140 is advanced distally over the cartridge 50 towards the received configuration until the outer barrel 140 reaches a lighting configuration as shown in
In the lighting configuration, the distal section 148 of the outer barrel 140 is positioned proximal of the heat source 54 such that the heat source 54 extends distally from the distal section 148. In the lighting configuration, a flame, e.g., a lighter or a match, can be used to ignite the heat source 54. During ignition of the heat source 54, the distal section 148 of the outer barrel 140 may be exposed to the flame. The entire outer barrel 140 or at least the distal section 148 of the outer barrel 140 may be constructed of or coated with a heat resistant material to prevent ignition of the outer barrel 140 during ignition of the heat source 54. During ignition of the heat source 54, the mouthpiece 112 may be positioned in the mouth of a user and the user may draw through the mouthpiece 112 during ignition of the heat source 54. As detailed above, with the outer barrel 140 in the lighting configuration, the cartridge 50 is secured within the holder 104.
After the heat source 54 is ignited, the outer barrel 140 is advanced over the cartridge 50 towards the received configuration as shown in
In the received configuration, the smoking article 100 may be used in a manner similar to a traditional cigarette. For example, the mouthpiece 112 may be used to draw an aerosol through the substrate portion 52 and the filters 115. The relief slits 149 in the distal section 148 of the outer barrel 140 may allow outside air to be drawn through the substrate portion 52 without passing through the internal passages 55 of the heat source 54 (
In some implementations, the heat source 54 may be sized to extinguish when the substrate material 51 within the substrate portion 52 is fully aerosolized. Full aerosolization of the substrate material 51 may be determined when all of the substrate material 51 is aerosolized or when a predetermined amount of the substrate material 51 is aerosolized. In some implementations, the smoking article of the present disclosure may include an extinguishment position. In such a manner, the extinguishment position may be configured such that the heat source is deprived of sufficient oxygen to sustain combustion. In some implementations, the extinguishment position may be obtained by further sliding the outer barrel distally. In other implementations, for example, one or more additional features may be included such that an extinguishment position may be achieved by actuating the one or more additional features. In particular, in one implementation the device may include a detachable feature, such as, for example an end cap, that may be used to achieve the extinguishment position. For example, in some implementations a separate end cap may be attachable over the distal end of the outer barrel such that, once attached, the heat source is deprived of sufficient oxygen to sustain combustion. Such an end cap could also be used to cover the end of the outer barrel when not in use, such as, for example, to prevent dirt and/or foreign objects from entering into the device.
When the heat source 54 is extinguished, the outer barrel 140 is retracted to the load position as shown in
Manipulation of the outer barrel 140, as detailed above, may be accomplished with one or two hands of a user. In addition, loading, lighting, and ejecting the cartridge 50 from the holder 104 may be accomplished without contacting the heat source 54.

In the received configuration, the smoking article 200 may be used in a manner similar to a traditional cigarette. For example, the mouthpiece 212 may be used to draw an aerosol through the substrate portion 52. Further, in the received configuration, when the heat source 54 is ignited with the cap 240 encapsulating the cartridge 50, the cap 240 protects from unintentional contact with the heat source 54. The vent holes 249 provide airflow to the heat source 54 such that the heat source 54 remains ignited. In some implementations, the vent holes 249 may be covered or blocked to extinguish the heat source 54. For example, a user may block the vent holes 249 with a finger to extinguish the heat source 54. In other implementations, one or more additional features may be included such that an extinguishment position may be achieved by actuating the one or more additional features. In particular, in one implementation the device may include an air impermeable cover feature located proximate the vent holes 249 that may be mechanically or manually actuatable (e.g., by rotating the cover feature over the end of the cap 240 and/or by sliding the cover feature across the end of the cap 240) such that in the extinguishment position, the cover feature substantially covers the vent holes 249 and the heat source is deprived of sufficient oxygen to sustain combustion.

In the received configuration, the smoking article 200 may be used in a manner similar to a traditional cigarette. For example, the mouthpiece 212 may be used to draw an aerosol through the substrate portion 52.
When the heat source 54 is extinguished, the cartridge 50 may be removed from the holder 204. The heat source 54 may be extinguished when the heat source 54 is exhausted or may be extinguished intentionally by covering the vent holes 249.
To remove the cap 240, the cap 240 is twisted relative to the main body portion 210 to move the nub 222 within the transverse segment of the groove 244 until the nub 222 is within the longitudinal segment of the groove 244. With the nub 222 in the longitudinal segment of the groove 244, the cap 240 may be pulled away from the main body portion 210 to remove the cap 240 from over the cartridge 50. With the cap 240 removed from over the cartridge 50, the proximal section 59 of the cartridge 50 may remain frictionally secured within the socket 234 of the main body portion 210. When the heat source 54 is extinguished, the cap 240 may be removed and the heat source 54 reignited in a similar manner as detailed above and the holder 204 returned to the received configuration by resecuring the cap 240 to the main body portion 210.
When the heat source 54 is exhausted, the user may eject or remove the cartridge 50 from the main body portion 210 and may replace the cartridge 50 with another cartridge 50. To remove the cartridge 50 from the main body portion 210, the user grasps the cartridge 50 to separate the cartridge 50 from the main body portion 210. Specifically, the user may grasp the outer housing 53 of the cartridge 50 and pull the cartridge 50 away from the main body portion 210 while holding the main body portion 210. With the cap 240 removed from over the cartridge 50, a significant portion of the outer housing 53 is exposed such that the user may grasp the outer housing 53 without contacting the heat source 54. In some implementations where the proximal portion 59 of the cartridge 50 is loose within the socket 234, the main body portion 210 may be tilted such that the connector 220 is oriented downward such that the cartridge 50 falls out of the socket 234 without grasping the outer housing 53 of the cartridge 50. With the cartridge 50 removed from within the socket 234, another cartridge 50 may be loaded into the socket 234, ignited, and the cap 240 replaced, i.e., secured to the main body portion 210, over the new cartridge 50. In some implementations, another cartridge 50 may be loaded into the socket 234 and the cap 240 replaced without the new cartridge 50 being ignited. In other implementations, the cap 240 may be replaced without a new cartridge 50 being loaded or ignited.
The holder 204 allows for the loading, lighting, smoking, and unloading of a cartridge 50 without contacting the heat source 54 of the cartridge 50. The holder 204 also encapsulates the cartridge 50 in the received configuration such that the heat source 54 is prevented from unintentionally contacting the user or other objects when the heat source 54 is ignited.

The holder 604 also substantially covers or encapsulates the cartridge 50 in the received configuration such that the heat source 54 is prevented from unintentionally contacting the user or other objects when the heat source 54 is ignited. Additionally, in the lighting configuration and the received configuration, the holder 604 secures the cartridge 50 thereto to prevent the cartridge 50 from unintentionally separating from the holder 604.
As detailed above, portions of the holders 104, 204, 304, 404, 504, 604 may be constructed of a flame or heat resistant material. Suitable flame or heat resistant materials may include, but are not limited to, a metal material such as, stainless steel, aluminum, brass, copper, silver, gold, and bronze; a graphite material; a ceramic material; or any combinations thereof. Although not shown in the depicted implementations, in some implementations the holder may include one or more openings that may correspond to one or more openings in the outer housing of the cartridge. Additionally or alternatively, other implementations may include one or more air inlet openings that extend through the holder downstream from the receiving compartment. In such a manner, drawn air may mix with the generated aerosol before being delivered to the user.
Some implementations may include an igniting mechanism, which may be activated by a user or may be automatic. In one example, the igniting mechanism may include an integrated flint lighter that may be independently activated by a user, or may be automatically activated when the holder, e.g., holders 104, 204, 304, 404, 504, 604, is advanced to the lighting configuration. Other implementations may include a fuel source, such as a fuel tank, that, in conjunction with an igniter, may produce a flame that ignites the heat source 54. In various implementations, activation of the igniting mechanism may occur via a mouthpiece of a holder or another component and/or may be integrated with the holder.
In some implementations, the smoking article, e.g., smoking article 100, 200, 300, 400, 500, 600, may further include an indicator configured to indicate a status of the cartridge 50. For example, in some implementations the indicator may provide a “fuel gage” that approximates how much substrate material in the cartridge may be available for aerosolization and/or how much substrate material has already been aerosolized. Another example of such an indicator may include thermochromatic visual indication of the substrate portion through its consumption cycle. Other examples may include a timer, clock, or progressive visual indicator that provides visual representation of the state of the substrate material. For example, some implementations may provide visual representation in the way of digital indicators, one or more components that change color, one or more lights (e.g., green, yellow, and red), or other progressive indicators. In some implementations, an indicator may provide indication to a user that the substrate portion has heated sufficiently for the user to begin smoking.
In various implementations, the present disclosure may be directed to kits that provide a variety of components as described herein. For example, a kit may comprise a holder with one or more cartridges. In another implementation, a kit may comprise a plurality of holders. In further implementations, a kit may comprise a plurality of cartridges. In yet another implementation, a kit may comprise a plurality of holders and a plurality of cartridges. The inventive kits may further include a case (or other packaging, carrying, or storage component) that accommodates one or more of the further kit components. The case could be a reusable hard or soft container. Further, the case could be simply a box or other packaging structure. In some implementations, a brush or other cleanout accessory may be included in a kit. The cleanout accessory may be configured to be inserted in a receiving chamber of the holder, or, in other implementations, inserted in a separate aperture that enables a user to remove debris from the receiving chamber.
Although a smoking article according to the disclosure may take on a variety of implementations, as discussed in detail herein, the use of the smoking article by a consumer will be similar in scope. The foregoing description of use of the smoking article is applicable to the various implementations described through minor modifications, which are apparent to the person of skill in the art in light of the further disclosure provided herein. The description of use, however, is not intended to limit the use of the inventive article but is provided to comply with all necessary requirements of disclosure herein.
Many modifications and other embodiments of the disclosure will come to mind to one skilled in the art to which this disclosure pertains having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that the disclosure is not to be 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. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
This application is a continuation application of U.S. patent application Ser. No. 16/516,573, filed on Jul. 19, 2019, which is incorporated herein in its entirety by reference.
