Description

Technical Field

[0001] The present disclosure relates to products containing tobacco and for human consumption; and more particularly to smoking articles that generate an inhalable aerosol having significantly reduced amounts of incomplete combustion and pyrolysis products compared to tobacco products that generate smoke by burning tobacco. Background Art

[0002] Common smoking articles such as cigarettes have a generally cylindrical rod-shaped structure and include a charge, roll or column of smokable material such as shredded tobacco (e.g., in the form of shredded filler) wrapped by a paper wrapper, thereby forming a so-called "smokable rod", "tobacco rod" or "cigarette rod". Generally, cigarettes have a cylindrical filter element that is aligned with the tobacco rod in an end-to-end relationship. Preferably, the filter element includes a plasticized cellulose acetate bundle surrounded by a paper material known as "plug wrap". Preferably, the filter element is attached to one end of the tobacco rod by using a surrounding wrapping material known as "tip wrap". In order to dilute the main smoke flow inhaled with ambient air, it is also desirable to perforate the corked material and the plug wrap. Cigarettes and their various components are described in "Tobacco Production, Chemistry and Technology" (1999) by Davis et al. A user uses a traditional type of cigarette by lighting one end of the cigarette and burning the tobacco rod. The user then draws mainstream smoke into his / her mouth by inhaling on the opposite end of the cigarette (e.g., the filter end or mouth end). Over the years, efforts have been made to improve the components, construction, and performance of smoking articles. See, for example, the background art discussed in U.S. Patent No. 7,753,056 to Borschke et al.

[0003] As an alternative to burning tobacco, certain types of cigarettes using carbon fuel elements have been marketed by RJ Reynolds Tobacco Company under the trade names "Premier", "Eclipse" and "Revo". These types of cigarettes are described, for example, 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, p. 158 (2000). Additionally, Japan Tobacco Inc. sells similar types of cigarettes in the Japanese market under the trade name "Steam Hot One".

[0004] In addition, various types of smoking products that include carbonaceous fuel elements for heat generation and aerosol formation have been described recently in the patent literature. See, for example, U.S. Patent Nos. 7,836,897 to Borschke et al.; 8,469,035 to Banerjee et al. and 8,464,726 to Sebastian et al.; 8,616,217 to Tsuruizumi et al.; 8,915,255 to Poget et al.; 9,578,897 to Gladden et al.; 9,185,939 to Zuber et al.; 7,692,123 to Baba et al.; 8,616,217 to Tsuruizumi et al.; 8,915,255 to Poget et al.; 9,578,897 to Gladden et al.; 9,185,939 to Zuber et al.; 9,692,123 to Baba et al.; 9,616,217 to Tsuruizumi et al.; 9,616,217 to Poget et al.; 9,616,217 to Tsuruizumi ... No. 7; U.S. Patent Publication No. 2012 / 0042885 to Stone et al.; U.S. Patent Publication No. 2013 / 0133675 to Shinozaki et al., and PCTWO No. 2013 / 098380 to Raether et al.; PCTWO No. 2013 / 098405 to Zuber et al.; PCTWO No. 2013 / 098410 to Zuber et al.; PCTWO No. 2013 / 104914 to Woodcock; PCTWO No. 2013 / 120849 to Roudier et al.; and PCTWO No. 2013 / 120854 to Mironov; the entire texts of which are incorporated herein by reference. For example, a historical perspective on the art related to various types of smoking products incorporating carbonaceous fuel elements for heat generation and aerosol formation may be found in the background of US Patent Publication No. 2007 / 0215167 to Llewellyn Crooks et al., which is also incorporated herein by reference.

[0005] In recent years, many other smoking articles have been proposed as improvements or alternatives to smoking products based on burning tobacco. Exemplary alternatives have included devices in which solid or liquid fuels are burned to transfer heat to tobacco, or in which chemical reactions are used to provide such heat sources. Examples include the smoking articles described in U.S. Pat. No. 9,078,473 to Worm et al., which are incorporated herein by reference.

[0006] The goal of improvements or alternatives to smoking articles is generally to provide the sensation associated with smoking a cigarette, cigar or pipe without delivering a significant amount of incomplete combustion and pyrolysis products. To this end, many tobacco products, flavor generators, and medicated inhalers have been proposed that employ electrical energy to vaporize or heat volatile materials or that attempt to provide the sensation of smoking a cigarette, cigar or pipe without burning the tobacco to a significant degree.

[0007] It would be highly desirable to provide a smoking article that would demonstrate the ability to provide the user with much of the enjoyment of smoking a conventional cigarette without delivering an aerosol containing significant amounts of incomplete combustion and pyrolysis products.

[0071] Figure 1A representative smoking article 10 in the form of a cigarette according to one aspect of the present disclosure is shown. The smoking article 10 may have the overall size, shape and overall appearance of a filtered cigarette. In the illustrated embodiment, the smoking article 10 has a rod-like shape and includes a heating portion 14 and a mouth end portion 18. A longitudinally extending, substantially cylindrical heating section 35 is positioned at the heating portion 14 (in some aspects, the heating portion is at the end of the smoking article 10, but this is not necessary). The heating section 35 includes a heat source 40 surrounded by a heat insulator 42, and the heat source is most preferably coaxially surrounded by an outer wrapping material 45. In the illustrated embodiment, the heat source 40 is preferably configured to be activated by direct ignition of the heating portion 14. That is, the heat source or fuel element is designed to ignite to burn or smolder, and thus generate heat. The smoking article 10 may also include a filter section 55 located at the opposite end (i.e., the mouth end portion 18) of the heating portion 14. The aerosol generating section 65 is located between the filtering section 55 and the heating section 35, and the aerosol generating section may include at least one aerosol generating cartridge 68 and optionally a tobacco rod 70. In various embodiments, other components may be present between the aerosol generating cartridge 68 and the mouth end portion 18. For example, in some embodiments, one or any combination of the following may be used, including: air gap; phase change material for cooling air; flavor release medium; ion exchange fiber with selective chemical adsorption capacity; aerogel particles as filter medium; and other suitable materials.

[0072] The aerosol generating section 35 most preferably includes a combustible heat source 40 having a generally cylindrical shape and containing a combustible carbonaceous material. Examples of combustible fuel elements are discussed in US 2017 / 0000188 of Nordskog, the entire text of which is incorporated herein by reference. Such combustible carbonaceous materials typically have a high carbon content. Preferred carbonaceous materials are primarily composed of carbon, with a carbon content typically greater than about 60%, typically greater than about 70%, often greater than about 80%, and often greater than about 90%, based on dry weight. Such combustible fuel elements may include components other than combustible carbonaceous materials (e.g., tobacco components, such as powdered tobacco or tobacco extracts; flavorings; salts, such as sodium chloride, potassium chloride, and sodium carbonate; thermally stable graphite fibers; iron oxide powder; glass filaments; powdered calcium carbonate; aluminum oxide particles; ammonia sources, such as ammonia salts; and / or binders, such as guar gum, ammonium alginate, and sodium alginate). For example, a typical heat source 40 has a length of about 12 mm and an overall outer diameter of about 4.2 mm. A representative heat source 40 can be extruded or composited using a ground or powdered carbonaceous material and has a density greater than about 0.5 g / cm3, often greater than about 0.7 g / cm3, and often greater than about 1 g / cm3, based on dry weight.

[0073] Another embodiment of the heat source 40 may include a foamed carbon monolith formed in a foaming process. In another embodiment, the heat source 40 may be coextruded with the insulation 42, thereby reducing manufacturing time and cost. Still other embodiments of heat sources, also referred to as fuel elements, may include those types described in U.S. Patent No. 4,819,655 to Roberts et al. or U.S. Patent Application Publication No. 2009 / 0044818 to Takeuchi et al., each of which is incorporated herein by reference.

No. 5,129,409 to White et al.; U.S. Pat. No. 5,211,684 to Shannon et al.; and U.S. Pat. No. 8,119,555 to Banerjee et al.

[0076] The heat insulation 42 of heating section 35 can be made of glass filament or fiber.The heat insulation 42 can serve as the sheath (for example, be configured between heat source and wrapping material 45) that helps to hold heat source 40 firmly in place in smoking article 10.In one embodiment, heat insulation 42 is provided in the form of glass filament nonwoven mat.The heat insulation 42 can be set to multilayer component, for example, comprises the inner layer or pad 75 of nonwoven glass filament, the middle layer 76 of reconstituted tobacco paper and the outer layer 77 of nonwoven glass filament.These layers can be concentrically oriented, or each layer is wrapped and / or surrounds heat source 40 in a continuous overlapping mode.Various other heat insulation embodiments can be molded, extruded, foamed or otherwise formed.The specific embodiment of thermal insulation structure can include those described in No. 2012 / 0042885 of U.S. Patent Application Publication of Stone et al., which is incorporated herein in its entirety by reference.

[0077] The thermal insulation may additionally be configured so that the air and aerosol being drawn can easily pass therethrough. Suitable thermal insulation components have been included in cigarettes of the types commercially sold under the trade names "Premier", "Eclipse", "Steam Hot One". Examples of thermal insulation materials, components of thermal insulation assemblies, configurations of representative thermal insulation assemblies within heat generating sections, wrapping materials for thermal insulation assemblies, and modes and methods for producing such assemblies and assemblies are additionally disclosed in U.S. Pat. Nos. 4,807,809 to Pryor et al.; 4,893,637 to Hancock et al.; 4,938,238 to Barnes et al.; 5,027,836 to Shannon et al.; 5,065,776 to Lawson et al.; 5,105,838 to White et al.; 5,119,837 to Banerjee et al.; 5,247,944 to Clearman et al. No. 7; No. 5,303,720 to Banerjee et al.; No. 5,345,955 to Clearman et al.; No. 5,396,911 to Casey, III et al.; No. 5,546,965 to White; No. 5,727,571 to Meiring et al.; No. 5,902,431 to Wilkinson et al.; No. 5,944,025 to Cook et al.; No. 8,424,538 to Thomas et al.; No. 8,464,726 to Sebastian et al. and No. 8,678,013 to Crooks et al.

[0078] In one embodiment, both ends of the heating section 35 are open to expose at least the heat source 40 and the heat insulation 42 at the heating portion 14. The heat source 40 and the surrounding heat insulation 42 can be configured so that the length of the two materials extend together (for example, the end of the heat insulation 42 is flush with the corresponding end of the heat source 40, and specifically at the downstream end of the heating section 35). Optionally, the heat insulation 42 can extend slightly beyond (for example, from about 0.5 mm to about 2 mm) one end or both ends of the heat source 40. In addition, the heat and / or hot air generated when the heating portion 14 is ignited during the use of the smoking article 10 can easily pass through the heating section 35, through the heat source 40 itself (for example, by extending through the longitudinal channel of the heat source 40) and / or longitudinally through the heat insulation 42 during the user's inhalation on the mouth end portion 18.

[0079] In one embodiment, the wrapping material 45 surrounds the insulation 42 on the longitudinally extending outermost surface of the heating portion 14 of the smoking article 10. The wrapping material 45 can be a paper wrapping material, such as, for example, the type of paper wrapping material used as the surrounding wrapping material of the insulation area of ​​the heat source section of the cigarettes sold under the trade names "Premier" and "Eclipse" by RJ Reynolds Tobacco Company. Therefore, the "wrapping material 45" may also be referred to as "outer wrapping paper 45" to indicate such an embodiment, but this does not limit the wrapping material 45 to a paper wrapping material.

[0080] The heat generating section 35 is preferably positioned with one end disposed at or very close to the end of the heating portion 14 and axially aligned in end-to-end series relationship with the downstream aerosol generating section 65. The close proximity of the heat generating section 35 to the heating portion 14 provides direct ignition of the heat source 40 of the heat generating section 35.

[0081] The cross-sectional shape and size of the heating section 35 can vary before combustion during use. Preferably, the cross-sectional area of ​​the fuel element / heat source 40 accounts for about 10% to about 35%, typically about 15% to about 25%, of the total cross-sectional area of ​​the heating section 35; while the cross-sectional area of ​​the outer or external area (including the insulation 42 and the associated wrapping material 45) accounts for about 65% to about 90%, typically about 75% to about 85% of the total cross-sectional area of ​​the heating section 35. For example, for a cylindrical smoking article having a circumference of about 24 mm to about 26 mm, a representative heat source 40 has a generally circular cross-sectional shape with an outer diameter of about 2.5 mm to about 5 mm, often about 3 mm to about 4.5 mm.

[0082] The mouth end portion 18 of the smoking article 10 may include a suitable mouthpiece, such as, for example, a filter section 55. The filter section 55 may be positioned at one end of the aerosol generating section 65, so that the filter section 55 and the aerosol generating section 65 are axially aligned with an end-to-end relationship, adjacent to each other and without obstruction therebetween. In one embodiment, when observed transversely to the longitudinal axis of the suction article 10, the overall cross-sectional shape and size of these sections 55 are substantially the same as each other. The filter section 55 may include a filter material 85, which may be packaged with a plug wrapping material 90 surrounding the surface extending longitudinally thereof. In one example, the filter material 85 includes plasticized cellulose acetate tow, or other suitable filter materials of cigarette types. The two ends of the filter section 55 may be open to allow aerosol to pass therethrough. In some cases, the filter section 55 may be configured to include any combination of plugs, gaps and conventional cigarette filter materials (e.g., cellulose acetate tow) as needed or desired.

[0083] The filter section 55 may also include a scent release feature. In one example, one or more crushable fragrance capsules may be included in a filter section of the type described in U.S. Pat. Nos. 7,479,098 to Thomas et al., 7,793,665 to Dube et al., and 8,186,359 to Ademe et al. Additional or alternative scent release features may include scent cords or delayed release capsules that release scent in response to heated air being drawn through the filter, with or without physical manipulation by the user.

[0084] The aerosol generating section 65 can be attached to the filtering section 55 using a tipping material 95. Examples of tipping materials are described, for example, in U.S. Pat. No. 7,789,089 to Dube et al., and U.S. Patent Application Publication No. 2007 / 0215167 to Crooks et al., U.S. Patent Application Publication No. 2010 / 0108081 to Joyce et al., U.S. Patent Application Publication No. 2010 / 0108084 to Norman et al., and U.S. Patent Application Publication No. 2013 / 0167849 to Ademe et al.; and PCT Patent Application Publication No. 2013 / 160671 to Dittrich et al.

[0085] The smoking article 10 may include air dilution means, such as a series of perforations, each of which may extend through the tipping material 95 and the plug wrap material 90 .

[0086] Representative smoking articles 10 have a length between about 80 mm and about 100 mm. For example, for a smoking article 10 having a length of about 85 mm, a representative heat generating section 35 may have a length between about 10 mm and about 15 mm, a representative aerosol generating section 65 may have a length between about 5 mm and about 55 mm, and a representative filtering section 55 may have a length between about 20 mm and about 30 mm.

[0087] A longitudinally extending, generally cylindrical aerosol generating section 65 is located downstream of the heat generating section 35. The aerosol generating section 65 includes at least one aerosol generating cartridge 68 and can optionally include a tobacco rod 70. In one embodiment, at least one aerosol generating cartridge 68 is located between the heat generating section 35 and the tobacco rod 70.

[0088] The aerosol generating cartridge 68 includes a capsule 100 configured to receive an aerosol precursor therein. At least a portion of the capsule 100 may be perforated or otherwise permeable, thereby retaining the aerosol precursor within the capsule while allowing the aerosol formed by the aerosol precursor to be released therefrom through the perforated / permeable portion when the capsule 100 or the aerosol precursor therein is heated. The aerosol precursor may act as an aerosol former and be substantially completely consumed into an aerosol. Alternatively, the aerosol precursor may be composed of a solid or semi-solid carrier 110 or a substrate in combination with an aerosol former or composition.

[0089] The use of one or more aerosol generating cartridges 68 can provide a significant improvement to the aerosol generating section found in a typical smoking article. Specifically, the aerosol generating cartridge 68 can be produced offline using a cartridge manufacturing machine. Then, the completed cartridge 68 can be removed from the cartridge manufacturing machine and loaded into a smoking article assembly machine to be combined with other components to form a smoking article 10. The aerosol generating cartridge 68 is configured to provide a plug-in module that can be produced in a large number of different types and inserted into the manufacturing process of the smoking article 10. Previously, in the online manufacturing process of the smoking article, an aerosol precursor would be included in the aerosol generating section, and in this prior manufacturing process, the smoking article assembly machine completed the step of adding the aerosol precursor. The use of the aerosol generating cartridge 68 avoids the step of charging the substrate in the online manufacturing process. The use of an aerosol-generating cartridge 68 can significantly increase the speed of production of the smoking article 10, particularly in embodiments where the aerosol precursor comprises small particles such as beads or pellets, which currently require a slow filling process to accommodate such small particles in conventional smoking articles. The aerosol precursor is not limited to the form factor of beads or pellets and may include many other suitable substrates, such as cut filler, which is described in more detail below.

[0090] The capsule 100 can be made of various materials. These materials include paper, tobacco, metal and combination thereof, such as laminated materials. The capsule 100 made of paper can be made of various papers known in the art for making smoking articles. The capsule 100 made of tobacco can be made of various extruded or reorganized sheet tobacco compositions known in the art. In a specific embodiment, the capsule 100 can be made of metal. The metal can be a thin foil. In one embodiment, a thin foil layer is stacked with a paper layer. Therefore, the capsule 100 can be made of well-known packaging or wrapping materials, and many of these materials are discussed in this article. In another embodiment, a metal sheet can be used to form a self-supporting capsule that is thick enough to keep a carrier 110 therein. In one embodiment, the capsule 100 is formed by aluminum sheet or stainless steel sheet. In certain embodiments, the metal sheet can have a thickness of about 12 microns to about 100 microns.

[0091] exist Figure 2 and 3 The enclosure 100 is shown in more detail in FIG. Figure 2 As shown in the perspective view of , the capsule 100 of the illustrated embodiment is a cylindrical shape with a longitudinal axis L. If the capsule 100 is used in the smoking article 10 with a typical cigarette shape, the cylindrical shape may be beneficial. The shape of the capsule 100 may alternatively adopt other shapes, such as an elongated tube shape with an elliptical, rectangular or square or other polygonal cross-section. In other embodiments, the capsule 100 may not be elongated and may be a cube or other suitable shape.

[0092] As from Figure 3 The capsule 100 of the illustrated embodiment may include a circumferential wall 120 having a first longitudinal end and a second longitudinal end relative to each other. The longitudinal ends of the circumferential wall 120 may be covered by corresponding first and second end walls 124, respectively, and the first and second end walls extend across the first and second longitudinal ends of the circumferential wall. The first and second end walls 124 may be integrated with the circumferential wall 120 or otherwise attached to the circumferential wall. The end wall 124 may include a plurality of perforations 128 or may be permeable. In the case where the end wall 124 has perforations, the number, size and arrangement of the perforations 128 may be changed to adjust the air flow through the capsule 100 generated by the user inhaling on the smoking article 10. This end wall 124 may have any number of perforations 128 ranging from about four to about one thousand. The perforations 128 are shown as being arranged in concentric circles, but may also be arranged in almost any pattern. The perforations may be arranged in a grid of rows and columns. The perforations may be arranged along radial lines extending from the center of the end wall 124 toward its periphery. The perforations may be more densely arranged near the center of the end wall 124, may be most densely arranged near the periphery of the end wall, or at some portion therebetween. Alternatively, the perforations may be evenly spaced across the end face (or end wall 124) of the enclosure 100. The size of the perforations 128 may vary to control the flow of air. In one embodiment, the perforations 128 may have a diameter ranging from about 1 micron to about 1000 microns. The perforations are not limited to circular holes, but may take alternative shapes, such as elliptical, rectangular, linear slits, curved slits, etc.

[0093] In each embodiment, the size and shape of the perforations 128 should be selected so that the aerosol precursor, which may include a solid or semi-solid carrier 110, remains retained within the capsule 100 and is unlikely to escape from the aerosol generating cartridge 68 before being sufficiently heated to form an aerosol. In several embodiments, the size, shape, and arrangement of the perforations 128 are predetermined and manufactured into the material of the end wall 124 by a process such as a laser-based combustion process. In other embodiments, the porosity, diffusivity, or permeability of the material of the end wall 124 is selected to provide the desired retention of the aerosol precursor and air flow without altering the material to specifically create the perforations. The perforations 128 or other openings that allow air flow provided in the end wall 124a at the first end of the capsule 100 are not necessarily the same as the number, size, shape, or arrangement of the perforations provided in the end wall 124b at the second end of the capsule 100. In one embodiment, providing an end wall 124 with the same configuration at each end of the aerosol generating cartridge 68 can improve manufacturing efficiency, because the tube will not rely on direction when assembled into the smoking article 10. This arrangement can be described as the capsule 100 is arranged to be mirror-symmetrical about the plane that divides the capsule between its first longitudinal end and the second longitudinal end. By designing the end wall 124 and the capsule 100 as a whole to be rotationally symmetrical about the longitudinal axis L, additional manufacturing efficiency can be provided. In another embodiment, the end wall 124 on each end of the capsule can be unique, wherein one of the end walls 124a is configured to configure toward the heating section 35, and the other end wall 124b is configured to configure toward the mouth end 18. The difference of the end walls 124a, 124b can change the function of the air flow entering the capsule 100, the aerosol flowing out from the capsule, and the thermal management.

[0094] exist Figure 2 In the illustrated embodiment, the end wall 124 of the enclosure 100 may be formed with a first end wall portion 130 and a second end wall portion 132. The first end wall portion 130 and the second end wall portion 132 may be substantially parallel to each other and offset from each other along the longitudinal direction L of the enclosure 100. The first end wall portion 130 may extend substantially perpendicular to the distal end of the circumferential wall 120. The second end wall portion 132 may be inserted relative to the distal end of the circumferential wall. The result of inserting the second end wall portion 132 may be the creation of at least one recess 140 that is recessed relative to the end face (e.g., the first end wall portion 130) of the aerosol generating cartridge 68. The recess 140 may provide a convective air gap between the heat source 40 of the heat generating section 35 and the aerosol precursor within the enclosure 100. The convective air gap created by the recess 140 may, for example, help reduce the scorching of the aerosol precursor.

[0095] The enclosure 100 can be manufactured by a variety of manufacturing methods. For example, the circumferential wall 120 can be initially formed. Then, one of the end walls 124 can be mounted to the longitudinal ends of the circumferential wall 120 by adhesive, friction fit, welding or other fixing means. The circumferential wall 120 can be integrally formed with one of the end walls 124. The integral construction of the circumferential wall 120 and one of the end walls 124 can be produced using an additive manufacturing process. Figure 3 )After being at least partially filled with an aerosol precursor, the aerosol generating cartridge 68 can be completed by adding a second end wall 124b to the opposite end of the circumferential wall 120 to substantially completely enclose the aerosol precursor and provide for retaining the optional carrier 110 within the chamber 150.

[0096] In one embodiment, the capsule 100 includes a preformed circumferential wall 120 (e.g., a tube). The tube may be made of a paper foil laminate. A metal wrapping material may be wrapped around the circumferential wall 120, wherein the end region extends beyond the end of the preformed circumferential wall 120. The end region of the wrapping material may be provided with perforations 128 before or after wrapping around the circumferential wall. Similarly, the wrapping material may also be other materials that may not require perforations to achieve the desired porosity or air permeability. In order to encapsulate each end of the circumferential wall, the end region of the wrapping material may then be folded, for example in an envelope or star-shaped manner. In one embodiment, before the aerosol precursor is added, one end of the circumferential wall 128 is closed by the folded end region of the wrapping material. Then, after the chamber within the circumferential wall is filled with the aerosol precursor, the other end of the circumferential wall is closed by the folded end region of the wrapping material. The folded end of the wrapping material forming the end wall 124 may be unsealed or fixed into a folded configuration by an adhesive. Alternatively, after folding, the wrapping material may be sufficiently plastically deformed to maintain the fold and substantially close the ends of the circumferential wall, so that no adhesive or other fixing features are required. To facilitate the folding step, crease lines, pre-stressed score lines, perforation lines or cut lines may be formed in the wrapping material before or after the wrapping material is provided around the circumferential wall. The arrangement of crease lines, score lines, etc. may be selected based on the shape of the ends of the circumferential wall to be closed.

[0097] The aerosol precursor configured to be received in the chamber 150 of the capsule 100 may include a carrier 110. The carrier 110 may be a part of an aerosol precursor that does not dissolve, evaporate or otherwise release substantially from the capsule 100 when properly heated. The carrier 110 may be selected based on factors such as its filling factor and cost to control the intensity of the aerosol produced, the cost of the product and the service life of the smoking article, which is usually measured by the number of puffs. The carrier 110 may adopt a variety of different solid or semi-solid forms and include any number of alternative aerosol forming agents. In one example, the carrier 110 may include a reconstituted tobacco material, which includes a processing aid, flavoring agent and / or glycerine. The carrier and / or aerosol forming agent may include tobacco. More specifically, if tobacco is included, the carrier may be composed of a mixture of, for example, flavor tobacco and aromatic tobacco in a shredded form. These tobaccos may be processed with an aerosol forming agent and / or at least one flavoring agent. Carrier 110 can also be made of processed tobacco (for example, reconstituted tobacco made by the process of using cast sheet or papermaking type) in the form of shredded filler. Some cast sheet structures can include about 270 mg to about 300 mg of tobacco per 10 mm cast sheet linear length. In other cases, carrier 110 can be made of a mixture of formed tobacco pellets. In specific aspects of the present disclosure, the carrier 110 composed of a certain form of tobacco can be treated or processed to include an aerosol forming agent, which can include at least one flavoring agent and a flame retardant (for example, diammonium phosphate, other similar types of salts and / or other suitable flame retardant materials). Flame retardant materials are included in carrier 110 and can be configured to prevent the carrier from catching fire.

[0098] As used herein, the term "tobacco pellets" is intended to include beads, pellets or other discrete small tobacco units that have been formed, shaped, compressed, extruded or otherwise molded into a desired shape. For example, tobacco pellets can be formed using a so-called pelletization process. Tobacco pellets can have a smooth, regular external shape (e.g., sphere, cylinder, ovoid, etc.) and / or they can have an irregular external shape. In one example, the diameter range of each tobacco particle can be from less than about 1 mm to about 2 mm. As described herein, tobacco pellets can at least partially fill the substrate cavity of a smoking article. That is, carrier 110 can take the form of pellets or other loose objects, and they occupy the space adjacent to the heating section 35 and located at the heating section 35 downstream in the capsule 100. In one example, the volume of capsule 100 can be in the range of about 500 cubic millimeters to about 700 cubic millimeters (e.g., cavity diameter is about 7.5 to about 7.8 mm and cavity length is about 11 to about 15 mm, wherein the cavity has a roughly cylindrical geometry). In one example, the mass of the tobacco pellets in the capsule 100 can be in the range of about 200 mg to about 500 mg. For example, the capsule 100 can be filled with tobacco pellets at a packing density of about 100 to about 400 mg / mm3. In one embodiment, the carrier 110 is formed in an extrusion process and can include glycerol, ground tobacco, calcium carbonate, a binder, flavoring agents, and water. More specifically, on a dry weight basis, the extrudate material can include about 37.86% ground tobacco, about 39.82% calcium carbonate, about 1.00% of a binder such as carboxymethyl cellulose (CMC) or cellulose gum, and about 21.32% glycerol and flavoring agents (wherein 20% is glycerol).

[0099] In other aspects, the material composition for extruding the rod, that is, for example, glycerine, ground tobacco, calcium carbonate, adhesive, flavoring agent and water, can be used to form a flat sheet material of about 0.3 millimeter to about 1.7 millimeters in thickness alternatively. In some cases, the sheet material can also be formed by extrusion process (or molding or casting, as the case may be), wherein the sheet material is subsequently dried to form carrier 110. The sheet material of drying can then be deconstructed, for example, by cutting the sheet material into strips, or shredding the sheet material. The cutting / shredding part of the shaped sheet material can then be stacked or gathered in a manner similar to cut filler tobacco (for example, as an alternative but in a similar manner depositing cut filler tobacco), and deposited in capsule 100.

[0100] In some respects, carrier 110 may include a cast sheet that for example includes tobacco material. This cast sheet can be formed in the process of casting, drying and cutting into a strip-shaped or shredded mixture containing selected tobacco. In some cases, the cut strips or shredded parts of the cast sheet can be mixed with other shredded fillers (for example, traditional shredded filler tobacco, wherein with or without additional aerosol forming agent), to provide the taste and sensory perception of user expectations, and to help manufacturing process. In a kind of example, selected tobacco-containing mixture can be characterized as pectin release mixture, which includes for example (by dry weight) about 66.60% of ground tobacco, about 3.75% of diammonium phosphate, about 4.65% of ammonium hydroxide and about 25% glycerine and flavorings. In order to process pectin release mixture, for example, ground tobacco, diammonium phosphate, ammonium hydroxide and water can be heated to about 160 ° F for about 1.5 hours, to improve or enhance the organoleptic quality of the resulting mixture. Then glycerine and flavorings can be added to the remainder of the mixture when cooling after the heating step. The resulting mixture can then be used to form a cast sheet.

[0101] In another example, the selected tobacco-containing mixture can be characterized as a non-ammoniation mixture, which comprises for example (by dry weight basis) about 65.62% grinding tobacco, about 4.50% sodium alginate, about 1.13% sodium hydroxide or other pH adjusting agents, about 25% glycerine and about 3.75% wood pulp. In order to process the non-ammoniation mixture, for example, grinding tobacco, sodium alginate and water can be heated to about 160 ° F for about 1.5 hours, to improve or enhance the organoleptic quality of the resulting mixture. Then hydration wood pulp, adhesive, glycerine and flavorings can be added to the remainder of the mixture when cooling after the heating step. The resulting mixture can be used to form a cast sheet subsequently.

[0102] In another example, the selected tobacco-containing mixture can be characterized as a reconstituted material containing tobacco, which comprises for example (by dry weight) about 51.8% tobacco pulp, about 4.2% wood pulp, about 22.0% concentrated tobacco extract and about 22.0% glycerine and flavoring agent. Sheet material can be formed by the reconstituted material containing tobacco in a manner similar to conventional reconstituted sheet material. For example, first remove water-soluble elements from the tobacco pulp sheet layer, and remaining tobacco pulp is concentrated to about 25% solid content. Wood pulp can be added to tobacco pulp to form a base weight that can vary between about 120 grams per square meter (gsm) and about 240gsm. Then glycerine is mixed (for example, with a ratio of 1:1) and added to the base sheet material with concentrated tobacco-derived nicotine (TDN) extract. The formed substrate can be dried then, and cut into strips or shredded. Similar to the cast sheet, the cut strips or shredded reconstituted sheet can be blended with other cut fillers (eg, conventional cut filler tobacco, with or without additional aerosol formers).

[0103] In another example, selected tobacco-containing mixture can be characterized as the traditional cut filler tobacco material with the glycerol content of raising.In this case, the cut filler tobacco can be loaded with about 5% to about 30% glycerol or interact with these glycerols.The cut filler tobacco material with the glycerol content of raising can be used as carrier (for example, substrate material) subsequently, or can be mixed with cast sheet material so that the gained mixture forms carrier and aerosol forming agent.Based on the glycerol amount required or expected, glycerol can be applied to the cut filler tobacco, for example, as the shell for cutting (for example, being applied to independent tobacco strip), as top dressing or as both.This cut tobacco with the glycerol content of raising can for example be mixed with various cast sheets, reorganized sheet and / or tobacco beads to form the content of capsule 100 as required or expected.

[0104] In another example, selected tobacco-containing mixture can be characterized as non-tobacco material.For example, the cast sheet material that is used to form the carrier, extrusion carrier or beaded (pelletization) form of the carrier can include calcium carbonate, rice flour, adhesive, diammonium phosphate, glycerine, flavoring agent, tobacco-derived nicotine (TDN) and water.More specifically, this non-tobacco cast sheet material can be made up of for example about 41.25% calcium carbonate, about 13.75% rice flour, about 6% ammonium alginate, about 5.5% wood pulp, about 3.5% diammonium phosphate and about 30% glycerine.In addition, tobacco-derived nicotine (TDN), some acid (for example levulinic acid and / or citric acid) and flavoring agent can be included in the glycerine. The carrier formed by extrusion or the carrier in beaded (pelletized) form can be composed of, for example, about 51.94% calcium carbonate, about 17.15% rice flour, about 1% TDN, about 1% carboxymethyl cellulose (CMC), about 0.66% levulinic acid, about 0.44% lactic acid, about 20% glycerol and about 9.41% flavoring agent. In some cases, the cast sheet can be processed into cut strips, shredded or processed into shredded filler form. In other cases, if the carrier 110 includes beads, the beads can be positioned in the capsule 100 to be adjacent to the heat generating section 35, or closest to the heat generating section.

[0105] In another example of a carrier formed of a non-tobacco material, tobacco-derived nicotine (TDN), glycerin (e.g., an aerosol former), and a flavorant, the flavorant can be added to an extruded ceramic substrate having a relatively high porosity (e.g., an extruded ceramic rod member of high porosity). In such cases, the ceramic rod member or members can be extruded to define one or more longitudinally extending channels (e.g., open channels or slots disposed about an outer surface and / or a conduit extending through a central portion of the rod member).

[0106] Encapsule 100 is not limited to being filled by a single type of carrier or a single aerosol forming agent composition. Any carrier and aerosol forming agent composition comprising flavoring agent and glycerine can be configured in combination in the encapsule 100. For example, encapsule 100 can be filled with a combination of cast sheet and / or recombinant sheet, each sheet is shredded or cut into strips, mixed with shredded filler tobacco processed with glycerine. Shredded filler tobacco can have various levels of glycerine, for example, about 5% to about 25%. In another example, the cast sheet shredded or cut into strips can be mixed with the beads containing tobacco.

[0108] The composition of the aerosol former portion of the aerosol precursor may vary, and the aerosol former portion is optionally combined by the carrier 110 and configured to provide an aerosol component when heated. The aerosol former contains components that can evaporate, aerosolize or be entrained in the air inhaled through the smoking article during use. Most preferably, these components alone or in combination provide sensory and organoleptic effects, such as aroma, flavor, mouthfeel, visible aerosol sensation, etc. Examples of components of the aerosol former that are inhaled into the user's mouth during inhalation include water (e.g., as water vapor), visible aerosol-forming materials (e.g., glycerol), various volatile flavors (e.g., vanillin or menthol), volatile components of tobacco (e.g., nicotine), etc.

[0109] Once enough heat is applied to a suitable aerosol forming agent, it just produces visible aerosol, or produces visible aerosol under the effect of aerosol forming conditions caused by the parts of the smoking article. Desirable aerosol forming agents produce visible aerosols that can be considered as "smoky". Suitable aerosol forming agents are chemically simple relative to the chemical characteristics of the smoke produced by burning tobacco. A visible aerosol forming agent is a polyol, and another aerosol forming agent includes glycerol, propylene glycol and mixtures thereof. If desired, aerosol forming agents can be combined with other liquid materials (e.g., water). For example, the formula of aerosol forming agents can include a mixture of glycerol and water, or a mixture of propylene glycol and water. See, for example, the various aerosol-forming materials cited in U.S. Pat. Nos. 4,793,365 to Sensabaugh, Jr., et al.; 5,101,839 to Jakob, et al.; 6,779,531 to Biggs, et al.; and 8,678,013 to Crooks, et al.

[0110] The mode that aerosol forming agent contacts with carrier 110 (for example tobacco material) can have variation.During the manufacture of these materials, aerosol forming agent can be applied to formed tobacco material, or can be included in processed tobacco material.Aerosol forming agent can be dissolved or dispersed in water into liquid or in other suitable solvent or liquid carrier, and is sprayed on the carrier.For example, can be referring to the U.S. Patent Application Publication No. 2005 / 0066986 of people such as Nestor.The amount of aerosol forming agent adopted with respect to the dry weight of carrier can have variation.

[0111] The material of cast sheet type can contain relatively high level of aerosol forming agent. Reconstituted tobacco made using paper type process can contain medium level of aerosol forming agent. Tobacco rods and tobacco cut fillers can contain lesser amount of aerosol forming agent. Various paper and non-paper substrates including gathered, stacked, stacked metal / metallic, strips, balls such as alumina beads, open cell foams, foamed monoliths, air permeable substrates and other materials can be used within the scope of the present disclosure. See, for example, U.S. Patent Nos. 5,183,062, 5,203,355 and 5,588,446 granted to Clearman.

[0112] The laminated paper or other wrapping material may be constructed according to the disclosure of US Pat. No. 6,849,085 to Marton, or according to other suitable methods and / or materials.

[0113] Further, various combinations and kinds of flavoring agents (including various materials that change the sense organ and / or organoleptic characteristics or properties of the mainstream aerosol of smoking articles) can be included in suitable smoking articles. The substrate material and various tobacco components of smoking articles can be processed with tobacco additives of the type traditionally used to make cigarettes, such as shell and / or top dressing components. Referring to the component types set forth in, for example, the U.S. Patent No. 8,678,013 to Crooks et al.

[0114] Figure 4 A second embodiment is shown in which the aerosol generating section 65 may include a plurality of aerosol generating cartridges 68. The contents of each capsule 100 of each aerosol generating cartridge 68 may be the same or different from each other. The differences may be in the form of differences in the carrier and / or differences in one or more components of the aerosol forming agent of the aerosol precursor. The differences in the aerosol forming agent may include differences in the flavoring agents or additives themselves or in the concentrations of those additives.

[0115] The aerosol precursor in each capsule 100 may be selected to take advantage of the thermal profile of the smoking article 10. The thermal profile of the smoking article 10 is understood to reflect that the portion of the smoking article at the heat generation section 35 is the hottest, and the portion(s) at a distance from the heat source 40 is relatively cooler. Thus, where there are two aerosol generating cartridges 68, the aerosol former within the cartridge towards the mouth end 18 of the smoking article may be selected to evaporate at a lower temperature than the aerosol former in the cartridge directly adjacent to the heat generation section 35.

[0116] In other embodiments, the capsule 100 of the aerosol generating cartridge 68 itself can be subdivided into sub-compartments. A portion of the carrier and / or aerosol forming agent in each sub-compartment can vary. The sub-compartments can be arranged in series along an axis intended to extend between the heating portion 14 and the mouth end portion 18 of the smoking article 10. In other embodiments, the sub-compartments can be arranged in parallel along the length of the capsule 100.

[0117] Whether extending along the longitudinal axis of the housing 100 or transverse to the longitudinal axis, the partition walls between the sub-compartments can be formed of a material similar to the circumferential wall 120 and the end wall 124 (e.g., paper, tobacco, metal foil, or combinations and laminates thereof). The material forming the partition walls can have a porosity, diffusivity, and / or permeability to promote a desired air flow through the aerosol generating cartridge 68 when the user inhales.

[0118] The aforementioned components of the aerosol generating section 65, including at least one aerosol generating cartridge 68 and an optional tobacco rod 70, can be arranged in and surrounded by a wrapping material 160. The wrapping material 160 can be configured to promote heat transfer from the heating portion 14 of the smoking article 10 (e.g., from the heat generating section 35) to the components of the aerosol generating section 65. That is, the aerosol generating section 65 and the heat generating section 35 can be configured to be in a heat exchange relationship with each other, wherein such a heat exchange relationship can be promoted by the wrapping material 160 that surrounds the heat generating section 35 and the aerosol generating section 65 to form a subassembly. The heat exchange relationship enables sufficient heat from the heat source 40 to be supplied to the aerosol generating section 65 to volatilize / aerosolize the aerosol forming agent for aerosol formation and generation. In some cases, the wrapping material 160 can be a discrete component relative to the outer wrapping material 45, or can be matched with the outer wrapping material 45 in various ways. In other cases, the wrapping material 160 may include an insulating material for thermally insulating the aerosol generating cartridge 68 from the outer wrapping material 45. For example, the wrapping material 160 may include a fiberglass mat having a thickness between about 50 microns and about 500 microns.

[0119] In one embodiment of the present disclosure, a heat exchange relationship is achieved by positioning the heat generating segment 35 and the aerosol generating segment 65 in series close to each other. In some cases, the segments can be arranged in series in end-to-end contact with each other. A heat exchange relationship can also be achieved by extending a thermally conductive material from the vicinity of the heat source 40 into and / or around the area occupied by the aerosol generating segment 65. For example, in one embodiment, a representative wrapping material 160 may include a thermally conductive element or properties for conducting heat from the heat generating segment 35 to the aerosol generating segment 65 (and / or maintaining heat interacting with the aerosol generating segment 65 along its length) so as to provide aerosolization of an aerosol former contained within at least the aerosol generating cartridge. In other embodiments, the representative wrapping material 160 and / or the outer wrapping material 45 may include thermally conductive properties for dissipating heat that is not directed from the heat generating section 35 to the aerosol generating section 65, and / or for distributing heat evenly or more consistently between the heat generating section 35 and the aerosol generating section 65, while still providing aerosolization of the aerosol forming agent contained in the enclosure 100 of at least the aerosol generating cartridge 68. Such a wrapping material 160 may be provided by a laminated paper / foil sheet, for example, consisting of an outer layer of a sheet of paper-type material and an inner layer of a thermally conductive metal foil sheet. The metal foil sheet forming the inner layer may extend, for example, from a region downstream of the heat source 40 and along at least a portion of the length of the aerosol generating section 65. The metal foil / inner layer laminate may be associated with the outer layer in the form of one or more discrete longitudinally extending strips secured to the outer layer, or in the form of a continuous sheet that cooperates with the outer layer to surround the region of the overlapping heat generating section 35 and the aerosol generating section 65.

[0120] In embodiments where the wrapping material 160 is selected for heat conduction, for representative smoking articles of the types described herein, the wrapping material in the form of a laminated paper / foil sheet may have a typical length (e.g., along the aerosol generating section 65) of between about 8 mm and about 50 mm. The laminated paper / foil sheet may be perforated, etched, embossed, or primed, e.g., to facilitate ease of manufacture. In some cases, the thickness of the foil used in the laminate may be varied or increased / decreased as needed or desired, e.g., between about 0.0001 inch and 0.005 inch, to change the performance of the laminated paper / foil sheet and / or reduce visual scorching of the paper sheet portion of the laminated paper and / or the outer wrapper 45.

[0121] The laminated paper / foil sheets of wrapping material 160 can be formed in different ways. For example, a thermally conductive ink (in some cases, a thermally conductive metallic ink) can be printed on the paper portion so that the printed ink forms a foil layer (sheet or strip) on the paper portion (and / or can be at least partially absorbed into / integrated with the paper portion). Such a thermally conductive ink can include, for example, carbon, graphite, graphene, silver, or any other suitable thermally conductive or heat conducting material or combination thereof to conduct heat along the paper portion, which in turn heats the aerosol generating cartridge to thereby generate an aerosol. In one embodiment, the thermally conductive ink can be printed on a foil or conventional cigarette paper according to a continuous pattern or a discontinuous pattern, and the basis weight of the cigarette paper ranges from about 20 gsm to about 100 gsm.

[0122] In other cases, thermally conductive or heat conducting materials such as, for example, metal foil (e.g., silver), conductive carbon materials (e.g., graphene), or any other suitable thermally conductive materials or combinations thereof may be deposited on conventional cigarette paper or otherwise attached to conventional cigarette paper in various configurations (e.g., discrete strips, entire sheets, complete coatings, etc.), for example, using "island placement" or selective deposition / fitting techniques, to facilitate ease of manufacture and enhance functionality. In any case, embodiments of laminated paper / foil sheets as wrapping material 160 may, in some cases, dissipate or redirect heat generated by heat generating section 35 to reduce scorching of outer wrapper 45 and / or other components of smoking article 10. Thus, the elimination of scorching may improve the user's taste or sensory perception of the generated aerosol.

[0123] In other embodiments, wrapping material 160 may comprise three layers of laminated sheets, which comprise cigarette paper layers, foil layers and tobacco paper layers. The tobacco paper layer composition can be changed and can be composed of the different ratios of tobacco of for example burley tobacco, flue-cured tobacco, oriental tobacco or any other suitable type or its combination. The tobacco inclusions in the tobacco paper layer can be up to about 85% tobacco, and the tobacco paper layer can have a basis weight ranging from about 20gsm to about 100gsm. In some cases, the three-layer form of wrapping material 160 can be made of tobacco paper / foil / tobacco paper as required or desired. In other cases, the double layer of tobacco paper / foil can be implemented, wherein the tobacco sheet can be laminated to the aluminum or other heat-conducting foil of thickness range from about 0.0005 inch to about 0.002 inch, wherein, the basis weight of this double-layer laminated sheet can be between about 60gsm and about 100gsm.

[0124] According to yet another embodiment, the wrapping material 160 may be configured as any of a paper foil sheet laminate, a paper foil paper sheet laminate, a paper foil tobacco sheet laminate, a non-woven graphite sheet, a non-woven graphite and graphene composite sheet, a graphene sheet, a graphene foil sheet laminate, a graphene foil paper sheet laminate, a paper graphene sheet laminate, a graphene ink printed on a paper sheet, a graphene ink printed on a foil sheet, a carbon nanotube coordinated with a paper sheet or foil sheet, a fullerene coordinated with a paper sheet or foil sheet, and a graphene coordinated with a paper sheet or foil sheet. In such cases, for example, where graphene comprises one of the outer layers of the laminate, it may be desirable for the graphene layer of the laminate to provide the initial layer of the laminate closest to the aerosol generating cartridge 68. In other cases, for example, in the case of a graphene foil sheet laminate, it may be desirable for the foil sheet layer of the laminate to provide the initial layer of the laminate closest to the aerosol generating cartridge 68, while the graphene layer functions as a thermal barrier between the aerosol generating cartridge 68 and the outer wrapping material 45, or the order may be reversed, with the graphene layer of the laminate being the initial layer of the laminate closest to the aerosol generating cartridge 68, while the foil sheet layer functions as a thermal barrier between the aerosol generating cartridge 68 and the outer wrapping material 45. In the case where the wrapping material 160 includes a thermally conductive layer and a paper sheet or foil sheet, an insulating or thermal layer may be disposed therebetween.

[0125] In embodiments including imprinting of, for example, graphene inks, the inks may be applied using various printing processes such as gravure, flexographic, offset, screen, inkjet, or other suitable printing methods to provide varying thicknesses, patterns, surface coverage, and composition gradients.

[0126] The outer wrapper 45 is generally configured to wrap around the heat generating section 35 and to extend longitudinally (downstream) so as to also wrap around the aerosol generating section 65 and along at least a portion of its length. When so fitted to wrap the components of the smoking article 10, the outer wrapper 45 also extends over the interface between the heat generating section 35 and the aerosol generating section 65. In some embodiments, the outer wrapper 45 may be treated, interacted with, or otherwise exposed with, for example, calcium carbonate (CaCO3), aluminum hydroxide, magnesium hydroxide, and / or combinations thereof as fillers in the paper matrix of the outer wrapper 45, at least as a scorch retardant.

[0127] Those skilled in the art will also appreciate that, when the wrapping material 160 and / or the outer wrapping material 45 are wrapped around appropriate components of a smoking article, the wrapping material 160 and / or the outer wrapping material 45 may have their opposite ends (e.g., angled overlapping ends formed along a longitudinally extending seam of the smoking article) sealed together, for example, by an adhesive material. Therefore, in some embodiments of the present disclosure, the adhesive material may also include a filler, such as, for example, calcium carbonate (CaCO3), aluminum hydroxide, magnesium hydroxide, and / or a combination thereof, to reduce, minimize, or eliminate scorching or carbonization of the adhesive material and / or the outer wrapping material 45 along the longitudinally extending seam of the outer wrapping material 45 wrapped around the components of the smoking article.

[0128] Additional ways and methods for assembling representative types of smoking articles are described in U.S. Patent Nos. 5,469,871 to Barnes et al. and 8,678,013 to Crooks et al.; U.S. Patent No. 9,149,072 to Conner et al.; and U.S. Patent Application Publication No. 2012 / 0042885 to Stone et al.; U.S. Patent Application Publication No. 2014 / 0261470 to Amiss et al.; and U.S. Patent Application Publication No. 2015 / 0157052 to Ademe et al.

[0129] In some embodiments, both ends of the aerosol generating section 65 are open to expose at least one aerosol generating cartridge. The heating section 35 and the aerosol generating section 65 together form an aerosol generating subsystem 170. The aerosol generating section 65 is positioned adjacent to the downstream end of the heating section 35 so that these sections are axially aligned in an end-to-end relationship. These sections can be adjacent to each other, or positioned in a slightly spaced relationship, which may include an optional buffer zone generated by a recess 140 in the end wall 124 of the capsule 100. When observed transversely to the longitudinal axis of the smoking article 10, the external cross-sectional shape and size of these sections will be substantially the same as each other. The physical arrangement of these components is preferably such that during the use of the smoking article 10 and during the entire time of the heat source actuation (e.g., ignition), heat is transferred from the heat source 40 (e.g., through a substrate including conduction and convection heat transfer) to the aerosol precursor 10.

[0130] As described above, one or more recesses 140 can reduce potential scorching or other thermal damage to portions of the aerosol generating section 65. Other thermal buffers may also be provided due to areas that are partially or substantially completely filled with non-combustible materials, such as, for example, metals, organics, inorganics, ceramics, or polymeric materials, or any combination thereof. The buffer thickness (length) may be from about 1 mm to about 10 mm or more, but the thickness (length) will typically be about 2 mm to about 5 mm. If desired, the buffer may include a catalytic material, such as a material including oxides and / or salts of cerium or copper ions or cerium and copper ions. See, for example, U.S. Pat. No. 8,469,035 to Banerjee et al.; U.S. Pat. No. 8,617,263 to Banerjee et al.; and U.S. Pat. No. 9,220,301 to Banerjee et al.

[0131] Reference Figure 1-4 The described smoking article 10 can be used in substantially the same manner as those cigarettes that have been commercially sold by RJ Reynolds Tobacco Company under the trademarks "Premier", "Eclipse" and "Revo" and by Japan Tobacco under the trademark "Steam Hot One". That is, the fuel element or heat source 40 is ignited using a match or cigarette lighter. The burning fuel element / heat source caused by such ignition generates heat that is transferred to the aerosol generating cartridge 68 within the aerosol generating section 65. The aerosol precursor including the aerosol former and tobacco flavorings and components is heated and volatilized / aerosolized to form an aerosol while within the capsule 100. The aerosol is entrained in the inhaled air and is inhaled into the user's mouth through the filter section 55.

[0132] Figure 5 Another embodiment of the present disclosure is schematically shown. Figure 1-4 4 shows an embodiment of a smoking article 10 configured to generate heat by igniting a heat source 40. Figure 5The smoking article 300 is configured to use electrical energy to generate heat to promote the formation of inhalable substances. An exemplary device is described in U.S. Patent Application Serial No. 15 / 799,365 filed by Sebastian et al. on October 31, 2017, which is incorporated herein by reference in its entirety. The smoking article 300 can also be characterized as a steam-generating article or a medicament delivery article. Therefore, such articles or devices can be modified to provide one or more substances (e.g., flavoring agents and / or active pharmaceutical ingredients) in an inhalable form or state. For example, the inhalable substance can be in the form of a vapor (i.e., a substance in a gas phase at a temperature below the critical point). Alternatively, the inhalable substance can be in the form of an aerosol (i.e., a fine solid particle or droplet suspension in a gas). For the purpose of simplification, the term "aerosol" used herein is intended to include vapor, gas or aerosol in a form or type suitable for human inhalation, whether visible or not, and whether it can be considered as a smoke-like form.

[0133] In some embodiments, the smoking article 300 may include a control body 310 and an aerosol source member 320. The control body 310 may be reusable, while the aerosol source member 320 may be configured for a limited number of uses and / or configured as a disposable. In various embodiments, the aerosol source member 320 includes an aerosol precursor contained in a capsule, which forms an aerosol generating cartridge 368. In order to heat the aerosol source member 320, specifically the aerosol precursor therein, at least a portion of the heating device may be positioned in a receiving portion provided in the control body 310. The heating device may generate heat using an electric current provided by one or more power sources, which may be rechargeable or replaceable. The heating device may be a resistive heater or an induction heater. In the case of using an induction heater, both the resonant transmitter and the resonant receiver may be substantially permanently contained in the control body 310. In other embodiments, the resonant receiver may be provided as a part of the aerosol source member 320. The resonance receiver may be a dedicated component of the aerosol source component 320, or the function of the resonance receiver may be performed by the aerosol generating cartridge 368 of the aerosol source component.

[0134] Figure 5 A device smoking article 300 according to an exemplary embodiment of the present disclosure is shown. The smoking article 300 may include a control body 310 and an aerosol source member 320. In various embodiments, the aerosol source member and the control body may be permanently or removably aligned in an operative relationship. In this regard, Figure 5The smoking article 300 is shown in a coupled configuration. Various mechanisms may connect the aerosol source member 320 to the control body 310, such as a threaded fit, a press fit, an interference fit, a slide fit, a magnetic fit, etc. In various embodiments, the control body 310 of the smoking article 300 may be substantially rod-shaped, substantially tubular, substantially cylindrical, or the control body may take another handheld shape, such as a small box shape.

[0135] In specific embodiments, one or both of the control body 310 and the aerosol source member 320 may be referred to as disposable or reusable. For example, the control body 310 may have a replaceable battery or a rechargeable battery, a solid-state battery, a thin-film solid-state battery, a rechargeable supercapacitor, etc., and thus be combined with any type of charging technology, including: connecting to a wall charger, connecting to a car charger (e.g., a cigarette lighter socket), and connecting to a computer such as through a universal serial bus (USB) cable or connector (e.g., USB 2.0, 3.0, 3.1, USB Type-C), connecting to a photovoltaic cell (sometimes referred to as a solar cell) or a solar cell solar panel, or a wireless radio frequency (RF) based charger. Further, in some embodiments, the aerosol source member 320 may include a disposable device.

[0136] In various embodiments of the present disclosure, the aerosol source component includes a heating portion 314 and a mouth end 318 portion, the heating end being configured to be inserted into the control body 310, and the user inhales on the mouth end portion to generate an aerosol. The heating portion 314 may specify any portion of the aerosol source component that is inserted into the control body 310. The heating portion is not limited to the distal end or terminal end of the aerosol source component. Some or all of the heating portion 314 may receive heat from the control body 310. Alternatively, some or all of the heating portion 314 may be configured to generate heat in the presence of eddy currents. In various embodiments, the heating portion 314 may include an aerosol precursor contained within an aerosol generating cartridge 368. In other embodiments, when the aerosol source component is mated with the control body, the aerosol generating cartridge 368 may be positioned in whole or in part outside the control body 310. The aerosol generating cartridge 368 may include components for use in the above-mentioned and Figure 1-4 An enclosure and an aerosol precursor consistent with any embodiment of an aerosol-generating cartridge 68 for use in the smoking article 10 shown in FIG.

[0137] In various embodiments, the mouth end portion 318 of the aerosol source component 320 may include a filter section 355, which may be made of cellulose acetate or polypropylene material. In various embodiments, the filter section 355 may increase the structural integrity of the mouth end portion 108 of the aerosol source component 320, and / or provide filtering capabilities if desired, and / or provide resistance to suction. For example, the product according to an embodiment of the present disclosure may exhibit a pressure drop of about 50 to about 250 mm of water column pressure drop at an air flow rate of 17.5 cc / sec. In another embodiment, the pressure drop may be about 60 mm to about 180 mm, or about 70 mm to about 150 mm. The pressure drop value may be measured using a Filtrona filter test station (CTS series) available from Filtrona Instruments and Automation Ltd or a quality test module (QTM) obtained from the Cerulean Division of Molins, PLC. The thickness of the filter section along the length of the mouth end portion 318 of the aerosol source member 320 can vary, for example, from about 2 mm to about 20 mm, from about 5 mm to about 20 mm, or from about 10 mm to about 15 mm. In some embodiments, the filter section 355 can be held in place by an overwrap material. The overwrap material can be consistent with the overwrap materials 45, 95, and 160 discussed above so as to couple at least one aerosol generating cartridge 368 to the filter section 355.

[0138] Exemplary types of overwrap materials, wrapping material components, and treated wrapping materials that can be used in the overwrap of the present invention are described in U.S. Pat. Nos. 5,105,838 to White et al.; 5,271,419 to Arzonico et al.; 5,220,930 to Gentry; 6,817,365 to Hancock et al.; 6,908,874 to Woodhead et al.; 6,929,013 to Ashcraft et al.; 7,195,019 to Hancock et al.; 7,216,652 to Fournier et al.; 7,276,120 to Holmes; and 7,275,548 to Hancock et al., all of which are incorporated herein by reference in their entirety. Representative wrapping materials are commercially available from Schweitzer-Maudit International as RJ Reynolds Tobacco Company Grades 119, 170, 419, 453, 454, 456, 465, 466, 490, 525, 535, 557, 652, 664, 672, 676, and 680. The porosity of the wrapping material can vary and is typically between about 5 CORESTA units to about 30,000 CORESTA units, typically between about 10 CORESTA units to about 90 CORESTA units, and typically between about 8 CORESTA units to about 80 CORESTA units.

[0139] In order to maximize the delivery of aerosols and flavoring agents, one or more layers of non-porous cigarette paper can be used to encapsulate the aerosol source member (with or without an outer wrapper), otherwise the delivery of these aerosols and flavoring agents may be diluted by radial (e.g., external) air penetration through the outer wrapper. Examples of suitable non-porous cigarette papers are commercially available from Kimberly-Clark Corp. as KC635, P8785, P878162, and 780635. Preferably, the outer wrapper is a material that is substantially impermeable to the vapor formed during use of the smoking article 300. If desired, the outer wrapper may include a resilient paperboard material, foil-lined paperboard, metal, polymeric material, etc., and the material may be surrounded by cigarette paper. As described elsewhere herein, the outer wrapper may include a tipping paper surrounding the component, and may optionally be used to attach a filter material to the aerosol source member.

[0140] In one example, the control body 310 facilitates the generation of heat with an induction heater 340. The induction heater 340 includes a resonant transformer including a resonant transmitter and a resonant receiver. Specifically, the control body 310 may include: a housing 342 including an opening 344 defined in a mating end thereof; a flow sensor (e.g., a suction sensor or a pressure switch); a control component 346 (e.g., a microprocessor alone or as part of a microcontroller, a printed circuit board (PCB) including a microprocessor and / or a microcontroller, etc.); a power source 348 (e.g., a rechargeable battery and / or a rechargeable supercapacitor); and an end cap including an indicator 350 (e.g., a light emitting diode (LED)).

[0141] Examples of power supplies are described in U.S. Patent No. 9,484,155 to Peckerar et al. and U.S. Patent Application Publication No. 2017 / 0112191 filed on October 21, 2015 by Sur et al., the disclosures of which are each incorporated herein by reference in their entirety. With regard to flow sensors, current regulating components and other current control components for aerosol delivery devices including various microcontrollers, sensors and switches are described in U.S. Pat. Nos. 4,735,217 to Gerth et al., 4,922,901, 4,947,874 and 4,947,875 to Brooks et al., 5,372,148 to McCafferty et al., 6,040,560 to Fleischhauer et al., 7,040,314 to Nguyen et al., and 8,205,622 to Pan, all of which are incorporated herein by reference in their entirety. Reference may also be made to the control scheme described in U.S. Pat. No. 9,423,152 to Ampolini et al., which is incorporated herein by reference in its entirety.

[0142] In one embodiment, the indicator 350 may include one or more light emitting diodes, quantum dot-based light emitting diodes, etc. The indicator 350 may be in communication with the control component 346 and, for example, when coupled to the control body 310, illuminate when the flow sensor detects that the user inhales on the aerosol source member 320.

[0143] Additional components may be employed in the smoking article of the present embodiment of the present disclosure. For example, U.S. Pat. No. 5,154,192 issued to Sprinkel et al. discloses an indicator for a smoking article; U.S. Pat. No. 5,261,424 issued to Sprinkel, Jr. discloses a piezoelectric sensor that can be associated with the mouth end of the device to detect user lip activity associated with inhalation and subsequent triggering of heating by a heating device; U.S. Pat.

[0145] Figure 5 The control body 310 of the embodiment depicted in the embodiment includes a resonant transmitter and a resonant receiver, which together form a resonant transformer. The resonant transformer of various embodiments of the present disclosure can take a variety of forms, including embodiments in which one or both of the resonant transmitter and the resonant receiver are substantially permanently located within the control body 310 of the smoking article 300.

[0146] exist Figure 5 In the particular embodiment depicted, the resonant transmitter includes a stackup including a foil material 360 surrounding a support cylinder 361, and the resonant receiver of the depicted embodiment includes a plurality of receiver pins 362 extending from a receiver base member 364. In some embodiments, the foil material may include electrical traces printed thereon, such as, for example, one or more electrical traces that may form a spiral pattern when the foil material is positioned around the resonant receiver in some embodiments. In various embodiments, the resonant receiver and the resonant transmitter may be constructed of one or more conductive materials, and in other embodiments, the resonant receiver may be constructed of ferromagnetic materials, including, but not limited to, cobalt, iron, nickel, and combinations thereof. In the embodiment shown, the foil material 360 is constructed of a conductive material and the receiver pins 362 are constructed of a ferromagnetic material. In various embodiments, the receiver base member 364 may be constructed of one or more non-conductive and / or insulating materials.

[0147] As shown, the resonant emitter 360 may extend adjacent to the mating end of the housing 342 and may be configured to substantially surround the portion of the heating portion 314 of the aerosol source member 320 including the aerosol generating cartridge 368. In this manner, the resonant emitter 360 of the illustrated embodiment may define a tubular configuration. Figure 5 As shown, the resonant transmitter 360 can surround the support cylinder 361. The support cylinder 361 can also define a tubular configuration and can be configured to support the foil material 360 so that the foil material 360 does not move into contact with the resonant receiver pin 362 and thus short-circuit the resonant receiver pin 632. In this manner, the support cylinder 361 can include a non-conductive material that can be substantially transparent to the oscillating magnetic field generated by the foil material 360. In various embodiments, the foil material can be embedded or otherwise coupled to the support cylinder. In the illustrated embodiment, the foil material 360 is mated to the outer surface of the support cylinder 361; however, in other embodiments, the foil material can be positioned at the inner surface of the support cylinder or completely embedded in the support cylinder.

[0148] In the illustrated embodiment, the support cylinder 361 can also be used to facilitate proper positioning of the aerosol source member 320 when the aerosol source member is inserted into the housing 342. Specifically, the support cylinder 361 can extend from the opening 342 of the housing 344 to the receiving portion base member 364. In the illustrated embodiment, the inner diameter of the support cylinder 361 can be slightly larger than or approximately equal to the outer diameter of the corresponding aerosol source member 320 (e.g., to produce a sliding fit), so that the support cylinder 361 guides the aerosol source member 320 to the correct position (e.g., lateral position) relative to the control body 310. In the illustrated embodiment, the control body 310 is configured so that when the aerosol source member 320 is inserted into the control body, the receiving portion pin 362 is located in the approximate radial center of the heating end 314 of the aerosol source member 320.

[0149] In various embodiments, the transmitter support member 361 may engage the inner surface of the housing 342 to provide alignment of the support member relative to the housing. Thus, due to the fixed connection between the support member 361 and the inductive transmitter 360, the longitudinal axis of the inductive transmitter may extend substantially parallel to the longitudinal axis of the housing 342. In various embodiments, the inductive transmitter 360 may be positioned so as not to contact the housing 342, thereby avoiding the transmission of current from the transmitter coupling device to the outer body. In some embodiments, an insulator may be positioned between the resonant transmitter 360 and the housing 342 to prevent contact therebetween. It is understood that the insulator and the support member may include any non-conductive material, such as insulating polymers (e.g., plastic or cellulose), glass, rubber, ceramic, and porcelain. Alternatively, in embodiments in which the housing is formed of a non-conductive material such as plastic, glass, rubber, ceramic, or porcelain, the resonant transmitter may be in contact with the housing.

[0150] In some embodiments, the aerosol generating cartridge 368 may be at least partially constructed of a conductive or ferromagnetic material to function as a resonant receiver. For example, as described above, the enclosure of the aerosol generating cartridge 368 may be aluminum or other metallic material that may be suitable for functioning as a resonant receiver. Additionally or alternatively, a carrier or other component of the aerosol precursor within the enclosure may be made of a material suitable for functioning as a resonant receiver, such as a material that will generate heat when an alternating magnetic field generated by a resonant transmitter is present. In other embodiments, the wrapping material 45, 95 used to assemble the aerosol source component 320 may include at least a portion thereof that is suitable for functioning as a resonant receiver, such as a foil layer. In further embodiments, a dedicated resonant receiver component is secured to the aerosol generating cartridge 368 when the aerosol source component 320 is formed. Figure 5Unlike the illustrated embodiment in which the resonant receiver comprises a pin 362 formed as part of the control body 310, each of the above-described variations implements the resonant receiver as part of the aerosol source member 320 for removal from the opening 344 when the aerosol source member 320 is depleted of aerosol forming agent.

[0151] As described above, the aerosol source member 320 of the present disclosure is configured to operate in conjunction with the control body 310 to generate an aerosol. Specifically, when the aerosol source member 320 is connected to the control body 310 (for example, when the aerosol source member is inserted into the control body), the resonant transmitter may at least partially surround, substantially surround, or completely surround the resonant receiver (for example, by extending around its periphery). Further, the resonant transmitter may extend along at least a portion of the longitudinal length of the resonant receiver, may extend along most of the longitudinal length of the resonant receiver, or may extend along substantially all or a longer length of the longitudinal length of the resonant receiver. In addition, in various embodiments, when the aerosol source member is inserted into the control body, the resonant receiver may extend at least a portion of the longitudinal length of the aerosol generating section 365, may extend along most of the longitudinal length of the aerosol generating section 365, or may extend along substantially all or a longer longitudinal length of the aerosol generating section.

[0152] In use, when the user inhales on the mouth end of the aerosol source member 320, the resonant transmitter can thereby generate an oscillating magnetic field. Since the resonant receiver is located within the area defined by the resonant transmitter, the resonant receiver can be exposed to the oscillating magnetic field generated by the resonant transmitter. Specifically, the resonant transmitter and the resonant receiver together form a resonant transformer. In some examples, the resonant transformer and related circuits including an inverter can be configured to operate according to a suitable wireless power transmission standard, such as the Qi interface standard developed by the Wireless Power Consortium (WPC), the Power Matters Alliance (PMA) interface standard developed by the PMA, the Rezence interface standard developed by the Wireless Power Alliance (A4WP), and the like.

[0153] According to an exemplary embodiment, a change in current in the resonant transmitter, such as directed from the power source to the resonant transmitter by the control component, may generate an alternating electromagnetic field that penetrates the resonant receiver, thereby generating eddy currents in the resonant receiver. The alternating electromagnetic field may be generated by directing an alternating current to the resonant transmitter. As described above, in some embodiments, the control component may include an inverter or an inverter circuit configured to convert direct current provided by the power source into alternating current provided to the resonant transmitter portion.

[0154] Eddy currents flowing within the material defining the resonant receiver may heat the resonant receiver by the Joule effect, where the amount of heat generated is proportional to the square of the current multiplied by the resistance of the resonant receiver material. In embodiments of the resonant receiver comprising ferromagnetic material, heat may also be generated by hysteresis losses. Several factors contribute to the increase in temperature of the resonant receiver including, but not limited to: proximity to the resonant transmitter, distribution of the magnetic field, resistivity of the resonant receiver material, saturation flux density, skin effect or depth, hysteresis losses, magnetic susceptibility, magnetic permeability, and dipole moment of the material.

[0155] In this regard, both the resonant receiver and the resonant transmitter may include conductive materials. For example, the resonant transmitter 25 and / or the resonant receiver may include various conductive materials, including metals such as copper and aluminum, alloys of conductive materials (e.g., diamagnetic, paramagnetic, or ferromagnetic materials), or other materials such as ceramics or glasses in which one or more conductive materials are embedded. In another embodiment, the resonant receiver may include conductive particles. In some embodiments, the resonant receiver may be coated with a thermally conductive passivation layer (e.g., a thin layer of glass) or otherwise include a thermally conductive passivation layer.

[0156] Thus, in various embodiments, the resonant receiver can be heated by the resonant transmitter. When the aerosol precursor is within the aerosol generating cartridge 368, the heat generated by the resonant receiver can heat the aerosol precursor so that an aerosol is generated within the cartridge. By positioning the resonant receiver near the aerosol precursor and at a substantially uniform distance therefrom, the aerosol precursor can be heated substantially uniformly.

[0157] The aerosol may be mixed with the air entering through the vent / inlet, which may be defined in the housing of the control body. For example, in some embodiments, the vent may be defined around the perimeter of the housing upstream of the heating end of the aerosol source component. Therefore, the air and aerosol mixture may be directed to the user. For example, the air and aerosol mixture may be directed to the user through a filter on the mouth end of the aerosol source component. However, it is understood that, without departing from the scope of the present disclosure, the flow pattern through the smoking article may be different from the above-mentioned specific configuration in any of a variety of ways.

[0158] In some embodiments, the aerosol source component may also include an authentication component that may be configured to allow the aerosol source component to be authenticated. Thus, for example, the control component may direct the current to the resonant transmitter only when the aerosol source component is verified to be authentic. In some embodiments, the authentication component may include a radio frequency identification (RFID) chip that is configured to wirelessly transmit a code or other information to the control body. Therefore, the smoking article may be used without the need for the electrical connector between the aerosol source component and the control body to be matched. Further, various examples of control components and the functions implemented thereby are described in U.S. Patent No. 9,854,841 to Ampolini et al., and the entire text of the above document is incorporated herein by reference.

[0159] As described above, in some embodiments, the control component of the control body may include an inverter or an inverter circuit configured to convert direct current provided by a power source into alternating current provided to the resonant transmitting portion. The inverter may also include an inverter controller implemented as an integrated circuit and configured to output a signal configured to drive the resonant transmitter to generate an oscillating magnetic field and induce an alternating voltage in the resonant receiver when exposed to the oscillating magnetic field. The alternating voltage causes the resonant receiving portion to generate heat, thereby generating an aerosol from the aerosol forming agent.

[0160] In some examples, the control body may also prevent the temperature of the resonant receiver from reaching or exceeding a threshold temperature. In some of these examples, the control component may include a microprocessor configured to receive a measured value of an alternating current induced in the resonant receiver. Then, the microprocessor may control the operation of at least one functional element of the smoking article in response to the measurement, such as reducing the temperature of the resonant receiver when the measured value indicates a temperature at or above a threshold temperature. One way to reduce the temperature may be to reduce, modulate and / or stop the current supplied to the resonant transmitter. Some examples are described in Sur's U.S. Patent Application Publication No. 2017 / 0196263, which is incorporated herein in its entirety by reference.

[0161] Further, other examples of various induction-based control components and related circuits are described in U.S. Patent Application Publication Nos. 2017 / 0202266 and 2017 / 0132531 to Sur et al., the entire text of each of which is incorporated herein by reference.
