Description

The present disclosure relates to products manufactured or produced from tobacco, or otherwise incorporating tobacco and intended to be ingested by humans, more specifically to produce smoke by burning tobacco. For segment-type smoking products that result in aerosols with significantly lower amounts of incomplete combustion and pyrolysis products compared to tobacco products.

Common smoking items such as cigarettes have a substantially cylindrical rod-like structure and charge, roll, or column of smokeable material (eg, in the form of cut filler) such as shredded tobacco. Is surrounded by wrapping paper to form a so-called "smoking rod", "cigarette rod", or "cigarette rod". Usually, the cigarette has a cylindrical filter element that is aligned with the tobacco rod so that the ends are connected to each other. Preferably, the filter element comprises a plasticized cellulose acetate tow surrounded by a paper material known as a "plug wrap". Preferably, the filter element is attached to one end of the tobacco rod using a surrounding packaging material known as "tipping paper". In addition, it has become desirable to provide holes in the chipping material and the plug wrap in order to dilute the mainstream smoke sucked in with the ambient air. Descriptions of cigarettes and their various components are described in Tobacco Production, Chemistry and Technology, Davis et al. (Eds.) (1999). Traditional types of cigarettes are used by smokers by igniting one end and burning a tobacco rod. Smokers then accept mainstream smoke into their mouth by inhaling it at the opposite end of the cigarette (eg, the end of the filter or the end of the mouthpiece). Over the years, efforts have been made to improve the components, structure, and performance of smoking products. See, for example, the background art described in US Pat. No. 7,735,056 by Borschke et al.

Certain types of cigarettes that use carbonaceous fuel elements are described in R.I. J. It is marketed by the Reynolds Tobacco Company under the brands "Premier" and "Eclipse". For example, Chemical and Biological Studies on New Cigarette Prototypes that Heat Instead of Burn Tobacco, R.M. J. Reynolds Tobacco Company Monograph (1988) and Inhalation Toxicology, 12: 5, p. See 1-58 (2000) for cigarettes of the type. In addition, recently, a similar type of cigarette has been released under the brand name "Steam Hot One" by Japan Tobacco Inc. Sold in Japan by.

In recent years, various types of smoking products incorporating carbonaceous fuel elements for heat generation and aerosol formation have been described in patent documents, and some patent documents have been produced by burning cigarettes. It provides a historical perspective on the technology of smoking products that result in aerosols with a relatively simple chemical composition compared to mainstream smoke.

Further, the smoking product 10 includes a filter segment 55 located at the opposite end (ie, the mouthpiece end 18) and an aerosol generation segment 61 located between the filter segment and the heat source.

The exothermic segment 35 most preferably has a generally cylindrical shape and includes a flammable fuel element 40 containing a flammable carbonaceous material. Such flammable carbonaceous materials generally have a high carbon content. Preferred carbonaceous materials are predominantly composed of carbon and are typically greater than about 60%, generally greater than about 70%, often greater than about 80%, and more often about 90% by dry weight. Has a carbon content greater than%. Such flammable fuel elements are components other than flammable carbonaceous materials (eg, tobacco components such as powdered tobacco or tobacco extract; flavoring agents; salts such as sodium chloride, potassium chloride, and sodium carbonate; heat; Stability Graphite fibers; iron oxide powder; glass filaments; powdered calcium carbonate; alumina granules; ammonia sources such as ammonia salts; and / or binders such as guar gum, ammonium alginate, and sodium alginate) can be included. A typical fuel element has, for example, a length of about 12 mm and an overall outer diameter of about 4.2 mm. Typical fuel elements can be extruded or formulated using crushed or powdered carbonaceous materials, exceeding about 0.5 g / cm 3 on a dry weight basis, often over ^{0.5 g / cm 3.} Has a density greater than about 0.7 g / cm ³ and more often more than about 1 g / cm ^3.

The layered insulation 42 can be made of glass filaments or fibers. The insulation 42 can function as a jacket that helps keep the heat source 40 firmly in place within the smoking product 10 (ie, the heat source and the outer packaging so as to secure the heat source inside the outer packaging material). Placed between the timber). Preferably, the insulation is provided in the form of a non-woven mat of glass filaments. The heat insulating material 42 may be provided as a multi-layer component including, for example, an inner layer or mat 67 of the non-woven glass filament, an intermediate layer of the reconstructed tobacco paper 68, and an outer layer of the non-woven glass filament 69. can. These layers may be arranged concentrically, or they may cover and / or surround the heat source in such a way that they overlap each other in succession.

Preferably, both ends of the heat generating segment 35 are open at the ignition end 14 so as to expose at least the heat source 40 and the insulation 42. The heat source 40 and the surrounding insulation 42 are of the same length in both materials (ie, the ends of the insulation 42 are flush with the respective ends of the heat source 40, especially at the downstream ends of the heat generating segment. Can be configured to be). Although not necessarily preferred, the insulation 42 can optionally extend slightly beyond either or both ends of the heat source 40 (eg, beyond about 0.5 mm to about 2 mm). .. Further, the heat and / or heated air generated when the ignition end 14 is ignited when the smoking product 10 is used passes through the heat source 40 itself (that is, the heat source 40) when the smoker sucks the mouth end 18. Through longitudinal channels extending through) and / or longitudinally through the insulation 42, it can easily pass through the heat generating segment 35.

Preferably, the outer packaging material 75 covers the outermost surface extending in the longitudinal direction of the ignition end 14 of the smoking product 10 and surrounds the heat insulating material 42. The outer packaging material 75 typically comprises, for example, R. cerevisiae. J. A wrapping paper material, such as a type of wrapping material used by the Reynolds Tobacco Company as a wrapping material around an insulating area of a heat source segment of a cigarette marketed under the brands "Premier" and "Eclipse". As described above, the "outer wrapping material 75" may also be referred to as the "outer wrapping paper 75" to indicate such an aspect, but the outer wrapping material 75 is not limited to the wrapping paper material.

A generally cylindrical aerosol-generating segment 61 extending in the longitudinal direction is located downstream of the heat-generating segment 35. Aerosol-forming segment 61 includes a substrate element 85 that includes a material that is itself an aerosol-forming agent or aerosol-forming material, or otherwise acts as a carrier for an aerosol-forming agent or aerosol-forming material (not shown). .. For example, aerosol-producing segments can include reconstituted tobacco materials containing processing aids, flavoring agents, and / or glycerin. The above-mentioned components of the aerosol-forming segment can be placed inside the packaging material 90 and surrounded by the packaging material 90. The packaging material 90 can be configured to facilitate the transfer of heat from the ignition end 14 of the smoked product 10 (eg, from the heat generating segment 35) to the components of the aerosol generation segment 61. That is, the aerosol generation segment and the heat generating segment can be configured in a heat exchange relationship with each other, and such a heat exchange relationship can be promoted by the packaging material 90. The heat exchange relationship is such that sufficient heat from the heat source 40 is supplied to the aerosol generation segment 61 to volatilize the aerosol-forming material (ie, combined with the substrate element 85) for aerosol formation and formation. It is a relationship. In some cases, the packaging material 90 may be a separate component of the outer packaging material 75, or may engage the outer packaging material 75 in various ways. In other cases, the packaging material 90 may include a heat insulating material for insulating the substrate element 85 from the outer packaging material 75. For example, the packaging material 90 can include a glass fiber mat having a thickness between about 50 μm and about 500 μm.

In one aspect of the present disclosure, the heat exchange relationship is achieved by arranging the exothermic segment 35 and the aerosol generation segment 61 in series in close proximity to each other. In some cases, these segments may be placed in series with their ends in contact with each other. A heat exchange relationship can also be achieved by extending the heat transfer material from the vicinity of the heat source 40 to the region occupied by the aerosol generation segment 61 and / or its surroundings. For example, in one embodiment, the representative packaging material 90 for the substrate element 85 is a heat-generating segment to result in volatilization of the aerosol-forming component contained in the aerosol-producing segment 61 (ie, combined with the aerosol-forming segment 85). A heat-conducting element or property for directing heat from 35 to the aerosol-forming segment 61 (and / or keeping the heat interacting with the aerosol-forming segment 61 along a length of the aerosol-forming segment 61). Can be included. In another embodiment, the representative packaging material 90 and / or the outer packaging material 75 is from the exothermic segment 35, while still providing volatilization of the aerosol-forming component contained in the aerosol-forming segment 61 or combined with the substrate element 85. Includes heat transfer properties to dissipate heat that is not directed to the aerosol generation segment 61 and / or to distribute heat uniformly or more consistently between the heat generation segment 35 and the aerosol generation segment 61. be able to. Such a packaging material 90 can be provided, for example, by a laminated paper / foil sheet composed of an outer layer 94 of a paper-type material sheet and an inner layer 96 of a thermally conductive metal foil sheet. The metal foil sheet 96 can be extended, for example, from a region downstream of the heat source 40 along at least a portion of the length of the aerosol generation segment 61. The metal foil / inner layer 96 flakes are placed in the form of one or more separate longitudinal strips attached to the outer layer 94, or in cooperation with the outer layer 94 into heat generating segments 35 and aerosol generation segments 61. It can be combined with the outer layer 94 in the form of a continuous sheet surrounding the overlapping areas described above.

In some aspects of the present disclosure that realize the packaging material 90, the provision of heat conduction of the packaging material 90 can be achieved in various ways. In general, the packaging material 90 in the form of a laminated paper / foil sheet has a typical length between about 8 mm and about 50 mm (ie, aerosol generation segment 61) in a typical smoking product of the type described herein. Along with) can have. Laminated paper / foil sheets can be perforated, etched, embossed, or primed, for example to increase ease of manufacture. In some cases, the performance of the laminate / foil sheet is altered and / or the paper sheet portion of the laminate and / or outer wrapping paper 75 wrapped around the wrapping paper 90 and / or aerosol generation segment 61 (ie, In order to reduce the visual scorching of the outer layer 94), the thickness of the foil used in the laminate may be varied, for example, between about 0.0001 inch and 0.005 inch, as needed or desired. Alternatively, it can be increased or decreased.

Laminated paper / foil sheets can be formed in a variety of ways. For example, a heat conductive ink (in some cases, a heat conductive metal ink) is used to print on a piece of paper, and the printed ink is used to form a foil layer (sheet or strip) on the piece of paper. (And / or may be at least partially absorbed / integrated into the paper portion). Such thermally conductive inks use, for example, carbon, graphite, graphene, silver, or any other suitable heat transfer or thermally conductive material, or a combination thereof, to conduct heat along a piece of paper. Can include heating the substrate element to generate an aerosol from the substrate element. Preferably, such a thermally conductive ink can be printed on a foil sheet or conventional cigarette paper according to a continuous pattern or a discontinuous pattern, and the cigarette paper has a basis weight of about 20 gsm to about 100 gsm. The range.

In other cases, heat transfer or heat transfer materials such as, for example, metal leaf (ie silver), conductive carbon material (ie graphene), or any other suitable heat transfer material, or a combination thereof, for example. Various configurations (ie, discrete strips, full) into traditional cigarette paper, for example using "island placement" or selective deposition / engagement techniques, to facilitate ease of manufacture and enhance functionality. It can be deposited with a sheet, complete coating, etc.) or attached in other ways. In each case, the realization of the laminated paper / foil sheet as the wrapping paper 90 has, in some cases, the heat-generating segment 35 to reduce the scorching of the outer wrapping paper 75 and / or other components of the smoked product. Dissipate the generated heat or direct it to another place. Thus, elimination of charring can improve the taste or perception of the aerosol produced to the user. That is, charred material can give the aerosol produced an undesired taste or perception, and reducing, minimizing, or eliminating such charring improves, for example, the flavor of the aerosol to the user and its Undesirable visual effects caused by such charring can be eliminated. Thus, some aspects of the disclosure are substrate elements that contribute or otherwise affect the aerosol generated by the exothermic segment 35 and directed towards the aerosol-generating segment 61, which is inhaled and experienced by the user. Includes configurations for more complete and efficient guidance and distribution without causing scorching of the 85, outer wrapping paper 90, or other components. In addition, since the aerosol-producing segment 61 can contain glycerin or other leachable material in some cases, various aspects of the packaging material 90 disclosed herein are glycerin or other leachate. Prevention or minimization of leaching of sex substances from the aerosol-producing segment 61 into the outer wrapping paper 75 can also be addressed. That is, some aspects of the disclosure are configured to prevent or minimize discoloration of the outer wrapping paper 75 that can be caused by glycerin or other leaching material leaching from the aerosol-producing segment 61. Can be included.

In some embodiments, the wrapping paper 90 may include cigarette paper / foil / tobacco paper in the form of a three-layer sheet, such a three-layer sheet configuration being, for example, a charred particular component of an aerosol. Alternatively, carbonization can be reduced, minimized, or eliminated, and more heat can be directed to the aerosol-generating segment 61, further facilitating an improvement in the taste or perception of the generated aerosol that the user experiences. Tobacco paper / sheet configurations may vary and consist of, including, for example, various proportions of Burleigh Pottery, tubing dried tobacco, oriental tobacco, or any other suitable type of tobacco, or a combination thereof. be able to. The tobacco content in the tobacco paper / sheet may be up to about 85% tobacco, and the tobacco paper / sheet can have a basis weight in the range of about 20 gsm to about 100 gsm. In some cases, the three-layer form of the wrapping paper 90 may consist of tobacco paper / foil / tobacco paper, if desired or desired. In other cases, two layers of tobacco paper / foil can be achieved, where the tobacco sheet is made into aluminum or other thermally conductive foil with a thickness in the range of about 0.0005 inches to about 0.002 inches. It can be laminated and such a two-layer sheet can exhibit a basis weight between about 60 gsm and about 100 gsm.

According to a further aspect, the wrapping paper 90 is 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. Graphene sheet, graphene-foil sheet laminate, graphene-foil-paper sheet laminate, paper-graphene sheet laminate, graphene ink imprinted on the paper sheet, graphene ink imprinted on the foil sheet, paper sheet or foil It can be configured as either carbon nanotubes engaged with the sheet, fullerene engaged with the paper or foil sheet, and graphene engaged with the paper or foil sheet. In such cases, for example, if the 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 substrate element 85. .. In another example, for example, in the case of a graphene-foil sheet laminate, the foil sheet layer of the laminate provides the initial layer of the laminate closest to the substrate element 85, while the graphene layer is with the substrate element 85. Acting as a heat shield between the outer packaging material 75, or in reverse order, the graphene layer of the laminate is the initial layer of the laminate closest to the substrate element 85, and the foil sheet layer is the substrate element 85. Can function as a heat shield between the outer packaging material 75 and the outer packaging material 75. When the wrapping paper 90 includes a heat conductive layer and a paper sheet or a foil sheet, a heat insulating layer or a heat layer can be arranged between them.

For example, in the embodiment of graphene ink imprinting, the ink is subjected to, for example, gravure printing, flexo printing, offset printing, screen printing, inkjet printing in order to give the ink various thicknesses, patterns, surface coverage, and composition gradients. , Or other suitable printing methods, can be applied using various printing processes.

In another embodiment, a graphene foil or graphene conductive sheet is placed between the cigarette paper (ie, the outer packaging material 75) and the aluminum foil (ie, the foil sheet layer incorporated in the wrapping paper 90) for outer packaging. A paper / graphene / foil laminate structure can be produced that includes the material 75 and the wrapping paper 90. In such cases, the graphene moiety can be completely wrapped (ie, between the inner and outer layers) to prevent or minimize the transfer or movement of material during the manufacture and use of the product. Can also prevent or minimize the leaching of glycerin from the substrate element 85 into the outer packaging material 75. However, packaging materials 90 configured to achieve the objects herein can be structured or constructed in a number of different ways, in addition to the various configurations disclosed herein. In this regard, one of ordinary skill in the art will appreciate that the typical configurations disclosed herein are not intended to be limiting.

The outer wrapping paper 75 is generally arranged around the heat generating segment 35, extends longitudinally (downstream), and is configured to wrap around the aerosol generation segment 61 along at least a portion of the length of the aerosol generation segment 61. NS. When so engaged around the above-mentioned components of the smoked product, the outer wrapping paper 75 also extends over the interface between the heating segment 35 and the aerosol-generating segment 61, thus eliminating or tending to burn. Minimization (and tendency to prevent leaching) can also be desirable. Thus, in some embodiments of the present disclosure, the outer wrapping paper 75 is at least as a filler in the paper matrix of the outer wrapping paper 75 as an anti-burning agent, such as calcium carbonate (CaCO ₃ ), aluminum hydroxide, hydroxide. It can be treated with magnesium and / or a combination thereof, can interact with them, or can be exposed to them in other ways.

When the wrapping paper 90 and / or the outer wrapping material 75 is wrapped around the appropriate components of the smoked product, for example, both ends sealed by an adhesive material (ie, a seam extending longitudinally along the smoked product). Those skilled in the art will also appreciate that they may have overlapping ends) in the angular direction forming the. Thus, in some aspects of the disclosure, the adhesive material is the adhesive material along the longitudinal seams of the outer packaging material 75 wrapped around the components of the smoked product and / or the charred outer packaging material 75. Alternatively, fillers such as, for example, calcium carbonate (CaCO ₃ ), aluminum hydroxide, magnesium hydroxide, and / or a combination thereof can also be included to prevent, minimize, or eliminate carbonation.

The substrate element 85, which forms part of the aerosol-forming segment 61, can include tobacco. More specifically, when tobacco is included, the substrate element 85 can be composed of a blend of flavored tobacco and fragrant tobacco, for example in the form of cut fillers. The tobacco can then be treated with an aerosol-forming material and / or at least one flavoring agent. The substrate element 85 can also be composed of processed tobacco in the form of cut fillers (eg, reconstituted tobacco produced using a cast sheet or papermaking type process). A particular cast sheet structure can include from about 270 mg to about 300 mg of tobacco per 10 mm straight length of the cast sheet. In other cases, the substrate element 85 can be composed of a mixture of formed tobacco pellets. Next, in certain aspects of the disclosure, the substrate element 85, configured in the form of tobacco, is subjected to an aerosol-forming material and / or at least one flavoring agent, as well as a combustion retardant (eg, diammonium phosphate, and others). Types of salts, and / or other suitable combustion retarding materials), or can be processed to include them. The inclusion of the combustion retarding material in the substrate element can be configured to prevent ignition of the material forming the substrate and / or prevent burning of the substrate element by the exothermic segment. In addition, the metal inner or surface 96 of the packaging material / outer layer 94 of the aerosol-forming segment 61 can serve as a carrier for the aerosol-forming material, tobacco component, and / or at least one flavoring agent.

As used herein, the term "tobacco pellets" is formed, molded, compressed, extruded, or otherwise made into the desired shape of tobacco beads, pellets, or other. Intended to include separate sub-units. For example, tobacco pellets can be formed using a so-called mulmarizing process. Tobacco pellets can have a smooth and regular shape (eg, sphere, cylinder, oval, etc.) and / or have an irregular shape. In one example, the diameter of each tobacco pellet may range from less than about 1 mm to about 2 mm. Tobacco pellets can at least partially fill the substrate cavity of the smoked product as described herein. That is, the substrate element 85 can take the form of pellets or other loose objects that occupy space in the aerosol-generating segment 61 downstream of the heat-generating segment 35 adjacent to the heat-generating segment 35. In one example, the volume of the substrate cavity ^{may range from about 500 mm 3} to about 700 mm ³ (eg, the cavity diameter is about 7.5 to about 7.8 mm and the cavity length is about 11 to about 15 mm. Yes, a base cavity for smoking products that has a generally cylindrical shape). In one example, the mass of tobacco pellets in the substrate cavity may range from about 200 mg to about 500 mg. For example, tobacco pellets are placed from about 100 to a suitable portion of the aerosol-producing segment 61 (eg, a cylindrical region inside the packaging material of the aerosol-generating segment 61 and bounded by the ends of the heat-generating segment 35 and the filter segment 55). It can be used to fill with a packing density of about 400 mg / cm ^3.

The configuration and arrangement of the substrate element 85 may vary according to the various aspects of the present disclosure. In one aspect, the substrate element 85 can be formed as a monolithic or integrated structure, for example, by an extrusion, molding, or casting process. In some preferred embodiments, the monolithic substrate element 85 can include tobacco or tobacco products. For example, in one embodiment, the monolithic substrate element 85 formed by the extrusion process may include glycerin, ground tobacco, calcium carbonate, binder, flavoring, and water. More specifically, on a dry weight basis, the extruded material is about 37.86% ground tobacco, about 39.82% calcium carbonate, about 1.00% binder such as carboxymethyl cellulose (CMC) or cellulose gum. , And about 21.32% glycerin and flavoring (~ 20% glycerin) can be included.

The monolithic substrate element 85 formed by an extrusion, molding, or casting process can have a variety of final forms and shapes, which form / shape facilitates improved heat transfer from the exothermic segment 35, and further. / Or charring or carbonization of the base component of the smoked product by facilitating the more efficient and effective distribution of heat to the base element 85 instead of the other base component of the smoked product. Can be promoted to reduce, minimize, or eliminate. For example, the extruded substrate element 85 can have the form and configuration of a monolithic grooved rod member 300 (see, eg, FIG. 4). That is, the rod member can include a plurality of lobes 310 arranged at different angles around the rod member, and adjacent lobes define an open channel 320 extending longitudinally between them. In some examples, the grooved rod member can further define one or more conduits 330 extending longitudinally through a central portion of the cross section or through one or more lobes. The location, dimensions, and / or configuration of open channels and / or conduits may vary to obtain specific performance characteristics, as needed or desired. For example, one effect of open channels is an increase in exposed surface area when compared to solid cylindrical rod members, which is in line with increased cigarette yields (ie, increased service life) and smoked products. It has effects such as reduction of pressure drop (that is, reduction of resistance to suction).

The effective diameter (ie, maximum outer diameter) of the grooved rod member may vary, for example, from about 5.8 mm to about 7.3 mm. In order to incorporate the grooved rod member into the aerosol-generating segment 61 (although any of the configurations of the packaging material 90 disclosed herein can be implemented as required or desired), the aerosol-generating segment is made of the outer packaging material 75. Prior to wrapping, larger diameter extrudes can be wrapped, for example, in a paper / foil laminate or paper / foil / paper laminate, while smaller diameter extrudes, eg, in a single layer of glass fiber mat. It can be wrapped and then further wrapped in either a paper / foil laminate or a paper / foil / paper laminate. The increase in surface area due to the grooved rod member results in a reduction in the surface area of the rod member in contact with the packaging placed between the rod member and the outer packaging material 75, thus leading to the outer packaging material 75 when using smoked goods. It will reduce the heat transferred. The internal conduit can provide additional surface area for the rod member heated by the heating segment, helping to draw some of the heat from the outermost surface of the grooved rod member (ie, the outermost surface of the lobe). be able to. In this way, the visual scorching of the outer packaging material 75 can be reduced. In addition, the increased surface area of the grooved rod member compared to the solid cylindrical rod member, which can be further increased by additional conduits, is incorporated into the substrate element 85 and exposed to heat from the heating segment 35. It can provide an additional volume of aerosol-forming material (ie, proportional to the surface area of the substrate element 85) and reduce the inhalation that the user needs to add to the smoked product. Therefore, such a smoking product can show an improvement in life as compared with a smoking product incorporating the base element 85 of a solid cylinder.

A paper / foil laminate or paper / foil / paper laminate that directly forms the encapsulation of the substrate element 85, or a paper / foil laminate or paper / foil / that forms with a single layer of glass fiber mats placed between them. Instead of any of the paper laminates, a two-layer or three-layer laminate of tobacco paper can be used as a wrap. In such cases, the initial layer of the wrap laminate may preferably contain tobacco paper, provided that the wrap receives heat from a heat-generating segment sufficient for carbonization or charring of the wrap. In this way, charring or carbonization of the tobacco paper layer can result in a tobacco flavor in the aerosol formed and thus has little or no adverse effect on the taste or perception of the aerosol formed. More specifically, tobacco paper such as a cast sheet or extruded tobacco paper can be laminated on a paper / foil two-layer laminate to form a paper / foil / tobacco paper three-layer laminate. , Tobacco paper provides an initial layer of laminate closest to the substrate element 85. Such a three-layer laminate configuration can be applied, for example, to both tobacco-containing and non-tobacco substrate elements, eg, seams formed by wrapping the three-layer laminate around the substrate elements (ie, tobacco). It is believed that a seam is formed between the paper and the tobacco paper forming the outer layer of the three-layer laminate), which can facilitate improved adhesion and the user's experience of aerosol taste and / or A positive side can be added to the perceptual traits. Those skilled in the art will appreciate the various tobacco-containing or tobacco-free described in the present disclosure of the types of paper / foil / tobacco paper three-layer laminates disclosed herein in understanding aspects of the invention of the present disclosure. It will be further understood that it can be applied to both substrate elements and aerosol-producing segments.

In another aspect of the present disclosure, the substrate element 85 takes the form of a plurality of solid cylindrical rod members 400 (see, eg, FIG. 5) extending parallel to each other from the interface between the heat generating segment 35 and the aerosol generation segment 61. Can be done. Such solid cylindrical rod members can be formed, if desired, by extrusion, molding or casting, eg, with glycerin, ground tobacco, calcium carbonate, binders, flavors, and water. Can be configured. In some examples, the solid cylindrical rod member can have a diameter of about 2.9 mm and a plurality of such rods are bundled or stacked for insertion into the aerosol generation segment 61 as a substrate element 85. be able to. After that, the solid cylindrical rod member as a set can be wrapped in the same manner as the configuration of the grooved rod member disclosed in the present specification under the same conditions.

In yet another embodiment, the material composition used for the extruded rod, eg, glycerin, ground tobacco, calcium carbonate, binder, flavoring, and water is used instead, from about 0.3 mm to about 1. A flat sheet with a thickness of between .7 mm can be formed. In some examples, the sheet can also be formed (or molded or cast as needed) by an extrusion process, after which the sheet is dried to form a substrate material. The dried sheet can then be disassembled, for example, by cutting the sheet into strips or shredding the sheet. The cut / shredded portions of the formed sheet are then stacked or collected and deposited as substrate element 85 on the aerosol production segment 61 in a manner similar to cut filler tobacco (ie, cut instead of cut filler tobacco). It can be deposited in the same way as filler tobacco).

In some embodiments, the substrate element 85 can be composed of, for example, a cast sheet containing tobacco material. Such cast sheets can be formed by the process of casting the selected tobacco-containing mixture, drying it, and cutting or shredding it into strips. In some examples, the cut pieces or shredded pieces of the cast sheet may or may not have other cut fillers (ie, additional aerosol forming agents, but traditionally. It can be mixed with (cut filler tobacco) to provide the user's desired taste and perception and facilitate the manufacturing process. In one example, the selected tobacco-containing mixture is, for example, about 66.60% ground tobacco (by dry weight basis), about 3.75% diammonium phosphate, about 4.65% ammonium hydroxide, and about. It can be characterized as a pectin free mixture containing 25% glycerin and flavoring. To treat the pectin free mixture, ground tobacco, diammonium phosphate, ammonium hydroxide, and water, for example to improve or improve the sensory quality of the resulting mixture, at about 160 ° for about 1.5 hours. It can be heated to F. Glycerin and flavoring can then be added to the remaining mixture upon cooling after the heating step. The resulting mixture can then be used to form cast sheets.

In another example, the selected tobacco-containing mixture is, for example (by dry weight basis) about 65.62% ground tobacco, about 4.50% sodium alginate, about 1.13% sodium hydroxide or the like. It is possible to characterize as a non-ammonized mixture containing a pH adjuster, about 25% glycerin, and about 3.75% wood pulp. To treat this non-ammonized mixture, milled tobacco, sodium alginate, and water are heated to about 160 ° F for about 1.5 hours, for example to improve or improve the sensory quality of the resulting mixture. be able to. The hydrated wood pulp, binder, glycerin, and flavoring can then be added to the remaining mixture upon cooling after the heating step. The resulting mixture can then be used to form cast sheets.

In another example, the selected tobacco-containing mixture is, for example (by dry weight basis) about 51.8% tobacco pulp, about 4.2% wood pulp, about 22.0% concentrated tobacco extract, It can also be characterized as a tobacco-containing reconstituted material containing about 22.0% glycerin and flavoring. The sheet can be formed from the tobacco-containing reconstituted material in a manner similar to a conventional reconstituted sheet. For example, the water soluble component is first removed from the tobacco pulp flakes and the remaining tobacco pulp is concentrated to a solid component content of about 25%. Wood pulp can then be added to tobacco pulp to form basesheets of varying basis weights between about 120 grams / square meter (gsm) and about 240 gsm. Glycerin is then mixed with the concentrated tobacco-derived nicotine (TDN) extract (ie, in a 1: 1 ratio) and added to the base sheet. The formed base sheet can then be dried and cut into strips or shredded. Similar to cast sheets, chopped strips or shredded reconstituted sheets may or may not have other cut fillers (ie, additional aerosol forming agents, but traditionally. It can be mixed with cut filler tobacco) (ie, traditional cut filler tobacco with or without additional aerosol forming agents).

In another example, it is possible to characterize the selected tobacco-containing mixture as a traditional cut-filler tobacco material with increased glycerin content. In such cases, the cut filler tobacco can contain or interact with between about 5% and about 30% glycerin. The cut filler tobacco material with a high glycerin content can then be used as the main substrate (ie, the substrate material forming the substrate element) or mixed with the cast sheet material and the resulting mixture is the substrate element. The substrate material can be formed. Based on the required or desired amount of glycerin, glycerin is applied to cut filler tobacco, for example as a casing for cutting (ie, applied to individual strips of tobacco), as a top dressing, or both. be able to. Such cut filler tobacco with a high glycerin content is mixed with, for example, various cast sheets, reconstituted sheets, and / or tobacco beads as needed or desired to provide a substrate material for the substrate element 85. Can be formed. In such cases of the base element 85 with high glycerin levels, it may be desirable to include an encapsulation of the base element 85 that minimizes or eliminates the leachation of the incorporated glycerin into the outer packaging material 75.

In yet another example, it is possible to characterize the selected tobacco-containing mixture as a non-tobacco material. For example, the cast sheet used to form the substrate element, the substrate element by extrusion, or the substrate element in the (malmerized) form of beads is calcium carbonate, rice flour, binder, diammonium phosphate, glycerin, flavoring, Tobacco-derived nicotine (TDN), and water can be included. More specifically, such non-tobacco cast sheets are, for example, about 41.25% calcium carbonate, about 13.75% rice flour, about 6% ammonium alginate, about 5.5% wood pulp. It can be composed of about 3.5% diammonium phosphate and about 30% glycerin. In addition, tobacco-derived nicotine (TDN), certain acids (ie, levulinic acid and / or citric acid), and flavors can be incorporated into glycerin. Extruded substrate elements, or substrate elements in the (malmerized) form of beads, eg, about 51.94% calcium carbonate, about 17.15% rice flour, about 1% TDN, about 1% carboxymethyl cellulose. It can be composed of (CMC), about 0.66% levulinic acid, about 0.44% lactic acid, about 20% glycerin, and about 9.41% flavor. In some cases, the cast sheet can be processed into cut pieces, shredded, or in the form of cut fillers. In other cases, when the substrate element 85 contains beads, the beads can be placed in contact with the heat-generating segment and adjacent to or closest to the heat-generating segment. In these cases, the selected components can be provided on the opposite side of the heating segment from the beads to secure the beads in place. For example, such selected components can include folded paper filter materials or other non-tobacco paper plugs.

In another example of the substrate element 85 made of non-tobacco material, tobacco-derived nicotine (TDN), glycerin (ie, aerosol-forming agent), and flavoring are extruded ceramic substrate with a relatively high porosity (ie, high). It can be added to the extruded ceramic rod member with porosity). In such cases, the ceramic rod member defines one or more longitudinal channels (ie, open channels or slots arranged around the outer surface, and / or conduits extending through the central portion of the rod member). Can be extruded to do. In a manner similar to the grooved rod member disclosed above, the increase in surface area due to the ceramic rod member (ie, due to the open channels around the surface) is due to the packaging placed between the rod member and the outer packaging material 75. This results in a reduced surface area of the rod members in contact, thus reducing the heat transferred to the outer packaging material 75 during use of the smoked product. The internal conduit can provide additional surface area for the rod member heated by the heating segment, to draw some of the heat from the outermost surface of the grooved ceramic rod member (ie, the outermost surface of the lobe). Can be useful. In this way, the visual scorching of the outer packaging material 75 can be reduced. In addition, the increased surface area of the grooved ceramic rod member compared to the solid cylindrical rod member, which can be further increased by additional conduits, is incorporated into the substrate element 85 and exposed to heat from the heating segment 35. It can provide an additional volume of aerosol-forming material (ie, proportional to the surface area of the substrate element 85) and reduce the inhalation that the user needs to add to the smoked product. Therefore, such a smoking product can show an improvement in life as compared with a smoking product incorporating the base element 85 of a solid cylinder.
