Description

The field of technology

The present invention relates to products manufactured or derived from tobacco or otherwise containing tobacco and intended for human consumption, and in particular to a segmented smoking product that produces aerosols containing significantly less incomplete combustion and pyrolysis products compared with tobacco products that produce smoke by burning tobacco.

Technical level

Popular smoking products such as cigarettes have a substantially cylindrical rod-like construction and contain a filler, roll or column of smoking material such as cut tobacco (eg in the form of a cut filler) surrounded by a paper wrapper, thus forming a so-called "smoking rod", "tobacco rod" or "cigarette rod". Typically, a cigarette has a cylindrical filter element that is aligned end-to-end with the tobacco rod. Preferably, the filter element comprises a tow of plasticized cellulose acetate fiber surrounded by a paper material known as " Preferably, the filter element is attached to one end of the tobacco rod by means of a surrounding wrapping material known as "casing paper". In addition, it is desirable to perforate the wrapping paper and the cassava in order to ensure dilution of the drawn main stream of smoke with ambient air. Descriptions of cigarettes and their of various components are presented in the publication Torasso Rgodisiop, SPetizigu apa Tesppoiosdu (Tobacco production, chemistry and technology) (Oami5 et al.) (Ed.) (1999). A smoker uses a traditional type of cigarette, lighting one end of the cigarette and burning the tobacco rod. In this case, the smoker takes the inhaled main stream of smoke into the mouth by taking puffs from the opposite end (for example, the filter side or the mouthpiece end) of the cigarette. Over the years, attempts have been made to improve the components, design and technical characteristics of smoking products. For example, US patent No. 7,7153,056 (Vog5spkKe, etc.) is described in the prior art.

Certain types of cigarettes that use carbon elements are marketed under the trademarks "Rgetieg" and "Esiirhe" by the tobacco company K. 9. Keupoid5 Torasso Sotrapu.

For example, these types of cigarettes are described in the monograph of Spetisai apa Viioodis! (tsadiye5z op Mem Sidagene

Zo Rgoioiurez Shai Neai Ipzivai oi Vygp Tobasso (Chemical and biological studies of new prototypes of cigarettes that heat tobacco instead of burning it) of tobacco company K.) Keupoid5 Tobasso

Sotrapu (1988) and scientific journal Ippaiacyop Tohisoiodu, 12:5, p. 1-58 (2000). In addition, a similar type of cigarette was recently released on the market in Japan under the trademark "Zeat

Noi Ope" by the tobacco company Udarap Tobasso Ips.

Various types of smoking products, which include carbonaceous fuel cells for heat generation and aerosol generation, have recently been presented in the patent literature; and several patent documents describe the historical perspective of technology relating to smoking products that deliver aerosols having chemical compositions that are relatively simple compared to the chemical composition of the mainstream smoke produced by burning tobacco. For example, types of smoking products and corresponding technologies are proposed in US patents Mo 7,647,932 (Sapigei! et al.), Mo 7,836,897 (Vog5spkKe et al.), Mo 8,469,035 (Vapegiee, et al.), Mo 8,464,726 (5erazyap et al.), Mo 8 616 217 (Tzygyi2giti et al.), Mo 8 678 013 (Stgookz et al.) and Mo 8 915 255 (Rodei et al.), US patent publications Mo 2012/0042885 (Ziope et al. etc.) and Mo 2013/0133675 (ZPipolaki et al.), international PCT applications UMO Me 2012/0164077 (SiIadayp et al.), Mo 2013/098380 (Kayeepsheg et al.), Mo 2013/098405 (7 reg. etc. .), Mo 2013/098410 (7 ibreg etc.), Mo 2013/104914 (MuUoodsosK), Me 2013/120849 (Kotsaieg and others), Me 2013/120854 (Migopom), UMO 2013/162028 (Aledati et al. ) and 20132/1600112 (Zaiet and others), ER 1808087 (Varva and others) and ER 2550879 (T5igii2yti and others).

It would be highly desirable to create smoking products that demonstrate the ability to provide the smoker with much of the enjoyment of traditional cigarettes without delivering an aerosol containing significant amounts of incomplete combustion and pyrolysis products.

DISCLOSURE OF THE ESSENCE OF THE INVENTION

The above and other needs are met by aspects of the present invention, in accordance with one of which there is provided an elongated smoking article having a lit end and an opposite mouthpiece end, such smoking article comprising a mouthpiece end portion located at the mouthpiece end and a heat generating portion located at the lit end. At least the heat generating portion is wrapped with an outer wrapping material that extends to the mouthpiece end portion so as to form a cylindrical core. Inside the outer wrapping material, between the heat-generating part 60 and the mouthpiece end part, there is an aerosol-generating part, which is designed to generate an aerosol when receiving heat from the heat-generating part, and the aerosol-generating part and the heat-generating part are also designed to interact to distribute heat , obtained by the aerosol generating part from the heat generating part in such a way as to prevent burning of the outer wrapping material.

Thus, in accordance with aspects of the present invention, there is provided a smoking article, in particular, a rod-shaped or elongated smoking article, such as a cigarette. The smoking article includes a lit end (ie, the upstream end) and a mouthpiece end (ie, the downstream end) located at opposite ends of the smoking article. Additionally, the smoking article includes an aerosol generating system that includes: (i) a heat generating region, portion, or segment and (ii) an aerosol generating region, portion, or segment that is downstream of the heat generating segment. The heat generation segment contains a relatively short (longitudinal) heat source or fuel element (ie, a heat generating element) that is made of a material such as a relatively clean combustible carbon-containing material.

The aerosol generating segment most preferably contains a substrate region, and in certain embodiments of the invention, the substrate region contains pellets or granules made of tobacco that are located in the substrate chamber. In an alternative embodiment of the invention, for example, the substrate region contains a material that includes reclaimed tobacco (for example, a material made from cut cast sheets). The substrate chamber or region of the substrate in which the substrate material is located is preferably surrounded along the length of the smoking article by a layer or strip of metal foil (eg, a heat-conducting type) that is layered over a paper-type wrapping material. The substrate, made at least partially of tobacco, serves as a carrier and source of aerosol-forming materials.

In accordance with certain aspects of the present invention, there is provided an elongated smoking article comprising a segment, region, or portion of a mouthpiece end located at the mouthpiece end, and a segment, region, or portion (or other suitably configured element) of a tobacco rod located between the lit end and the portion mouthpiece end.

Z The aerosol generating system is located in the form of a segment between the heat generating segment and part of the mouthpiece end. In other words, the segment generating the aerosol is located adjacent in the longitudinal direction to the heat-generating part or segment located at the ignited end; and heat is exchanged between the two segments such that the heat produced by the combustion of the components of the heat-generating segment affects the aerosol-forming components of the aerosol-generating segment, resulting in the generation of an aerosol. The longitudinally extending outer surfaces of the heat generating segment and the aerosol generating segment are surrounded by an outer wrapping material so as to form a core which in turn is attached to the mouthpiece end segment. Underneath the outer wrapping material is a layer of thermally conductive material so as to form the outer inner surface of the aerosol generating segment. The heat-conducting layer most preferably covers the outer longitudinal surface of the heat-generating segment in its region, which is adjacent to the aerosol-generating segment; and the heat-conducting layer, if necessary, can cover the outer longitudinal surface of the segment of the tobacco rod in its region, which is adjacent to the segment that generates the aerosol. Certain materials in the aerosol generating segment generate an aerosol when exposed to heat generated by the combustion of the heat generating segment's fuel cell.

In some aspects, the fuel element or heat source of the heat generating segment may contain material that can be characterized as carbonized or pyrolyzed material resulting from the carbonization or pyrolysis of cotton material. In this regard, it may be preferred and/or desirable for the fuel element/heat source to be ignited and remain burning (ie smoldering) but without emitting a flame when the smoking article is consumed, while producing sufficient heat to actuate of the aerosol-generating segment in order to produce an aerosol. In this regard, aspects of the present invention may be directed, for example, to a fuel element/heat source designed or positioned to allow for easy ignition or ignition. In some cases, existing fuel elements/heat sources made of traditional materials can be optimized to provide the desired ignition/ignition characteristics of the smoking product. In other cases, existing fuel elements/heat sources composed of traditional materials may be incorporated with other substances, such as additives (ie researched carbon or short cotton fibers) and/or catalysts, to improve their ignition/ignition characteristics. Typical aspects of such fuel cells/heat sources are disclosed, for example, in US Patent Application Mo. 14/755,205 (Mogazkod et al.).

In some aspects, the substrate region (aerosol generating system) comprises a form of tobacco that produces tobacco smoke that exhibits desired sensory characteristics. For example, the substrate region may contain a mixture of the following components: (a) pellets or granules made from tobacco that act as carriers for an aerosol-forming material such as glycerin (ie, the aerosol-forming material may be incorporated or otherwise incorporated into the pellets/pellets or brought into contact with with granules/pellets and attached to them with a gelling agent/sealing material to preserve the integrity of the aerosol-forming material with the granule/pellet against heat during use); and (i) a form of tobacco that produces tobacco smoke that exhibits the desired sensory characteristics. Alternatively, for example, the substrate region may contain a mixture of the following components: (i) pieces or particles of sheets of reconstituted tobacco material acting as carriers of an aerosol-forming material such as glycerin; and (its) form of tobacco producing tobacco smoke that exhibits the required sensory characteristics. In specific aspects, the substrate region/aerosol generating system, alone or together with the heat generating segment, may be designed to more evenly or efficiently transfer and distribute heat directed from the heat generating segment to the substrate region/aerosol generating system. In a preferred embodiment, such increased uniformity or efficiency of heat transfer and distribution directed from the heat generating segment to the region of the substrate/aerosol generating system also preferably reduces, minimizes or eliminates burning of the outer wrapping material of the smoking product. In addition, such increased uniformity or efficiency of heat transfer and distribution directed from the heat-generating segment to the substrate/aerosol-generating system region may also reduce the burning of the substrate/aerosol-generating system region itself, or at least contribute to the reduction or minimization of negative sensory effects caused by burning of the substrate on the aerosol inhaled and consumed by the user.

IMPLEMENTATION OF THE INVENTION

The following is a more detailed description of the present invention with reference to the accompanying drawings in which some, but not all, aspects of the invention are shown. It should be noted that this invention can be implemented in various forms and should not be considered as limited to the aspects described in this application; more precisely, these aspects are presented in such a way that the present invention satisfies the relevant requirements of the law. Identical elements in all drawings have the same item numbers.

In fig. 1 depicts a typical smoking article 10 in the form of a cigarette in accordance with one aspect of the present invention. In a preferred embodiment, the smoking article 10 has the general size, shape and general appearance of a filter cigarette. The smoking product 10 has a rod-like shape and includes a burning end 14 and a mouthpiece end 18. On the burning end 14 is located a generally cylindrical heat-generating segment 35, which runs longitudinally. The heat-generating segment 35 contains a heat source 40 surrounded by insulation 42, which is most preferably coaxially surrounded by an outer wrapping material 45. The heat source 40 is preferably made with the possibility of activation by means of direct ignition of the ignited end 14. In other words, the heat source or fuel element is made with the possibility kindling so as to burn or smolder and thus produce heat. In addition, the smoking product 10 includes a filter segment 55 located at the opposite end (ie, the mouthpiece end 18) and an aerosol generating segment 61 located between the filter segment and the heat source.

The heat-generating segment 35 most preferably contains a combustible fuel element 40, which has a generally cylindrical shape and contains a combustible carbon-containing material. Such combustible carbonaceous materials usually have a high carbon content. Preferred carbonaceous materials consist predominantly of carbon and typically have a carbon content greater than about 60 95, usually greater than about 7095, often greater than about 8095, and often greater than about 9095 on a dry weight basis. Such combustible fuel cells may contain components that differ from combustible carbonaceous materials (e.g., tobacco components such as powdered tobacco or tobacco extract; aromatics; salts such as sodium chloride, potassium chloride, and sodium carbonate; heat-resistant graphite fiber; oxide powder iron; glass filaments; calcium carbonate powder, aluminum oxide granules; ammonia sources such as ammonium salts and/or binders such as guar gum, ammonium alginate and sodium alginate). A typical fuel cell, for example, has a length of about 12 mm and a total outer diameter of about 4.2 mm. A typical fuel cell may be extruded or compounded using a pulverized 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. in terms of dry weight.

The multilayer insulation 42 may contain glass filaments or fibers. The insulation 42 may act as a sheath to help securely hold the heat source 40 in place within the smoking article 10 (ie, positioned between the heat source and the outer wrapping material so as to lock the heat source within the outer wrapping material). In the preferred embodiment of the invention, the insulation is made in the form of a non-woven mat made of glass threads. The insulation 42 can be made as a multi-layered component, for example, one comprising an inner layer or mat 67 of non-woven glass filaments, an intermediate layer of regenerated tobacco paper 68, and an outer layer of non-woven glass filaments 69. These layers can be concentrically oriented or each of they may wrap and/or surround the heat source in a continuous manner.

In a preferred embodiment of the invention, both ends of the heat-generating segment 35 are open to provide access to at least the heat source 40 and the insulation 42 at the fired end 14. The heat source 40 and the surrounding insulation 42 can be made in such a way that the length of both materials is the same (i.e. the ends of the insulation 42 located flush with the corresponding ends of the heat source 40 and, in particular, at the downstream end of the heat-generating segment). If necessary, although it is not necessarily preferred, the insulation 42 may protrude slightly (eg, about 0.5 mm to 2 mm) beyond either or both ends of the heat source 40 . In addition, heat and/or heated air generated at

From the ignition of the ignited end 14 during use of the smoking article 10, it can easily pass through the heat-generating segment 35 when the smoker draws from the side of the mouthpiece end 18, through the heat source 40 itself (ie, through the longitudinal channel passing through the heat source 40) and/or in in the longitudinal direction through insulation 42.

In a preferred embodiment, the outer wrapping material 75 surrounds the insulation 42 over the outermost surface extending longitudinally of the lit end 14 of the smoking article 10. This outer wrapping material 75 is typically a paper wrapping material similar to that used as a wrapping material that surrounds areas of insulation of segments of the heat source of cigarettes, presented on the market under the trademarks "Rgetieeg" and "Esiirhe" by the tobacco company K. 9. Keupoid5 Torasso Sotrapu.

In this regard, "outer wrapping material 75" may also be referred to as "outer wrapping paper 75" to denote such aspects, but not limiting outer wrapping material 75 to paper wrapping material.

In a preferred embodiment, one end of the heat-generating segment 35 is located at or very close to the edge of the ignited end 14 and is axially aligned end-to-end with the downstream aerosol-generating segment 61, which are preferably adjacent to each other preferably by the absence of a barrier (different from open space) between them. The direct proximity of the heat-generating segment 35 to the ignited end 314 provides direct ignition of the heat source 40 of the heat-generating segment 35.

The cross-sectional shape and dimensions of the heat-generating segment 35 prior to combustion during use may vary. In a preferred embodiment of the invention, the cross-sectional area of the fuel element/heat source 40 is about 10 95 to 3595, often about 15595 to 2595, of the total cross-sectional area of the heat-generating segment 35; while the cross-sectional area of the outer or surrounding region (containing the insulation 42 and corresponding outer wrapping materials) is about 65 95 to 90 95 , often about 75 95 to 85 95 of the total cross-sectional area of the heat generating segment 35. For example, for a cylindrical smoking article 10, having a circumference of about 24 mm to 26 mm, a typical fuel element/heat source 40 has a generally circular cross-section with an outer diameter 60 of about 2.5 mm to 5 mm, most often about mm to 4.5

MM.

The components of the heat-generating segment may vary. One component of the heat-generating segment is a fuel cell. Suitable fuel cells typically contain carbonaceous materials having a high carbon content and may also contain ingredients such as graphite and/or aluminum oxide. Carbonaceous fuel cells include the types of components and configurations included in cigarettes marketed under the trademarks "Rgetieg", "EsiIirhe" and "Meat Noi Ope". In addition, typical variants of heat-generating segments, characteristics of fuel cells, their typical components, designs and configurations, as well as techniques and methods of manufacturing these heat-generating segments and their fuel cells are described in US patents Mo 4,714,082 (Vapegtsgeee, etc.), Mo 4 756,318 (Sivagtanp, etc.), Mo 4,881,556 (Sivaptap, etc.), Mo 4,989,619 (Sivagtap, etc.), Mo 5,020,548 (Rattieg, etc.), Mo 5,027,837 (Sivaptap, etc. .), Mo 5,067,499 (Vapeptspee, etc.), Mo 5,076,297 (Ratieg, etc.), Mo 5,099,861 (SiIeaptap, etc.), Mo 5,105,831 (Vapegiee, etc.), Mo 5,129 409 (M/pye and others), Mo 5 148 821 (Vevi and others), Me 5 156 170 (Sivaptap and others), Me 5 178 167 (Kidu5 and others), Me 5 211 684 (Zpappop and others .), Mo 5,247,947 (Sivagtap, etc.), Mo 5,345,955 (Siepgtap, etc.), Mo 5,461,879 (Vagpe5, etc.), Mo 5,469,871 (Vagpez, etc.), Mo 5,551 451. 8,617,263 (Vapegiee and others) and Mo 8,678,013 (Stook5); and publications of US patent applications MO 2005/0274390 (Wapegiee et al.),

Some fuel cells may include a high-carbon carbonaceous material derived from a cotton-containing fiber (eg, cotton staples) that has been carbonized or pyrolyzed. Descriptions of materials made of carbonized or pyrolyzed cotton short fibers, as well as methods of incorporating these materials into smoking products, carbonized smoking materials, and fuel cells are presented in patents

Zo (Vapegiee and others). The fuel element of the heat-generating segment is most preferably surrounded or otherwise closed by insulation or other suitable material. The insulation can be designed and used to support, store and hold the fuel cell in place within the smoking article. The insulation can be additionally made in such a way that inhaled air and aerosol can easily pass through it.

Suitable insulating assemblies are included in cigarette types marketed under the Rgetieg, Esiirbhe and Zieat Noi Ope trademarks.

Further downstream from the heat-generating segment 35 is a generally cylindrical segment 61 that generates an aerosol that passes in the longitudinal direction.

The aerosol-generating segment 61 includes a substrate element 85 containing a material that is itself an aerosol-generating agent or aerosol-generating substance or otherwise acts as a carrier for the aerosol-generating agent or material (not shown).

For example, the aerosol generating segment may contain reconstituted tobacco material that includes processing additives, flavoring additives, and/or glycerin. The above components of the aerosol generating segment may be located within and surrounded by the wrapping material 90. The wrapping material 90 may be designed to provide heat transfer from the burning end 14 of the smoking product 10 (eg, from the heat-generating segment 35) to the components of the aerosol-generating segment 61. In other words, the aerosol-generating segment and the heat-generating segment can be made capable of heat exchange with each other, and such heat exchange can be facilitated by the wrapping material 90. The heat exchange between them ensures the supply of a sufficient amount of heat from the heat source 40 to the segment 61, that generates an aerosol, for the evaporation of the aerosol-generating material (i.e., the substrate associated with the element

85) for the purpose of generating and forming an aerosol. In some cases, the wrapping material 90 may be a separate component relative to the outer wrapping material 75 or may interact with the outer wrapping material 75 in various ways. In other cases, the wrap material 90 may include an insulating material to isolate the substrate element 85 from the outer wrap material 75. For example, the wrap material 90 may include a fiberglass mat having a thickness of about 50 μm to 500 μm.

In one aspect of the present invention, the implementation of heat exchange is provided due to the sequential location of the heat-generating segment 35 and the aerosol-generating segment 61 in close proximity to each other. In some cases, these segments may be sequentially arranged end to end in contact with each other. In addition, heat transfer can be achieved by passing a heat-conducting material from the region near the heat source 40 to the region occupied by the aerosol-generating segment 61 and/or around this region. For example, in one aspect, the typical wrapping material 90 for the substrate element 85 may include thermally conductive elements or properties for transferring heat from the heat generating segment 35 to the aerosol generating segment 61 (and/or maintaining thermal interaction with the aerosol generating segment 61 along its length) in order to ensure the evaporation of the aerosol-forming components contained therein (ie, the substrate associated with element 85). In other aspects, the typical wrap material 90 and/or the outer wrap material 75 may have thermally conductive properties to dissipate heat that is not directed from the heat generating segment 35 to the aerosol generating segment 61 and/or to distribute the heat evenly or more consistently between the heat generating segment 35 and segment 61, which generates an aerosol, while ensuring the evaporation of aerosol-forming components contained in the segment 61, which generates an aerosol, or associated with the element 85 of the substrate. Such a wrapping material 90 can be provided, for example, with a layered sheet of paper-foil containing an outer layer 94 made of a paper sheet and an inner layer 96 made of a sheet of metal foil. The metal foil sheet 96 may, for example, extend from an area downstream of the heat source 40 and along at least part of the length of the aerosol generating segment 61. The metal foil layer/inner layer 96 may be associated with

With the outer layer 94 in the form of one or more separate longitudinally extending strips attached to the outer layer 94 or in the form of a continuous sheet that, together with the outer layer 94, surrounds the specified area, overlapping the heat-generating segment 35 and the segment 61, which generates an aerosol.

According to the aspects of the present invention related to the wrapping material 90, ensuring its thermal conductivity can be implemented in various ways. Typically, the wrapping material 90 in the form of a layered sheet of foil paper may have an approximate length (ie, along the aerosol generating segment 61) of about 8 mm to 50 mm for a typical smoking product described herein. A layered sheet of paper-foil can be perforated, etched, embossed or treated with a primer, for example, to facilitate manufacturing. In some cases, the thickness of the foil used in the laminated sheet may be varied or increased/decreased as necessary, for example from about 0.0001 inch to 0.005 inch to change the characteristics of the paper-foil laminate and/or to reduce visible part burn paper sheet (ie outer layer 94) and/or outer wrapping material 75 wrapped around wrapping paper 90 and/or aerosol generating segment 61.

A layered sheet of paper-foil can be made in different ways. For example, a part of the paper may be coated with a thermally conductive ink (in some cases a thermally conductive metallic ink) in such a way that the applied ink forms a layer (sheet or strip) of foil on the paper part (the foil) or may at least partially be absorbed/combined with the part Such thermally conductive inks may include, for example, carbon, graphite, graphene, silver or any other suitable thermally conductive material or combination thereof to transfer heat along a portion of the paper so that the heat transferred in turn heats the substrate element for In a preferred embodiment of the invention, such thermally conductive inks can be applied in a continuous pattern or a discontinuous pattern onto a sheet of foil or conventional cigarette paper with a density of approximately 20 g/m to 100 g/m.

In other cases, a thermally conductive material such as a metal foil (e.g. silver), a conductive carbon material (e.g. graphene) or any other suitable thermally conductive material or combination thereof may be deposited or otherwise attached in various configurations (e.g. , in the form of individual strips, full sheet, finished coating, etc.) onto traditional cigarette paper, for example using "island placement" or selective placement/interaction technology, for example to facilitate manufacturing and improve functionality. In any case, the implementation of the laminated paper-foil sheet as the wrapping paper 90 may in some cases dissipate or redirect the heat that is generated by the heat-generating segment 35 to reduce burning of the outer wrapping paper 75 and/or other components of the smoking product. In this regard, elimination of burning can improve the taste or sensory perception of the produced aerosol for the user. In other words, burnt materials can impart an undesirable taste or sensory perception to the produced aerosol, and reducing, minimizing or eliminating such burning can, for example, improve the taste of the aerosol to the user and eliminate undesirable visual effects caused by such burning. Accordingly, aspects of the present invention provide a means to more fully and effectively direct and distribute the heat generated by the heat generating segment 35 to the aerosol generating segment 61 without burning the substrate element 85, the outer wrapping paper 90, or other components affecting the an aerosol that is inhaled and consumed by the user. Additionally, since the aerosol generating segment 61 may, in some cases, contain glycerin or other extractables, various aspects of the wrap material 90 described herein may also be directed to preventing or minimizing the extraction of glycerin or other extractables. substances extracted from the aerosol generating segment 61 to the outer wrapping paper 75. Thus, aspects of the present invention may include a wrapping material 90 that is designed to prevent or minimize discoloration of the outer wrapping paper 75 that may be caused by the extraction of glycerin or other extractable substance from the aerosol generating segment 61.

In some aspects, the wrapping paper 90 may contain cigarette paper, foil, and tobacco paper in the form of a three-layer sheet, the configuration of which may further provide an improvement in the taste or sensory perception of the produced aerosol that is consumed by the user, for example, by reducing, minimizing, or eliminating burning or charring of particular components of the smoking product and by directing more heat to the aerosol generating segment 61. Composition of tobacco paper/sheet

The tobacco may vary and may contain different proportions of, for example, burley tobacco, flue-cured tobacco, oriental tobacco, or any other suitable tobacco, or a combination thereof. The inclusion of tobacco in the tobacco paper/sheet can be up to 85 95 and the tobacco paper/sheet can have a density in the range of about 20 g/me to 100 g/me. In some cases, the three-layer wrapping paper form 90 may consist of tobacco paper/foil/tobacco paper as needed or desired. In other cases, a two-layer sheet of tobacco paper or foil may be implemented, in which the tobacco sheet may be layered over an aluminum or other thermally conductive foil having a thickness in the range of about 0.0005 inch to 0.002 inch, and the two-layer sheet may have a density of about from 60 g/m? up to 100 g/m".

According to additional aspects, the wrapping paper 90 may be made of any of the following materials: laminated paper-foil, laminated paper-foil-paper, laminated paper-foil-tobacco, non-woven graphite sheet, non-woven composite graphite-graphene sheet, graphene sheet, graphene-foil layered sheet, graphene-foil-paper layered sheet, paper-graphene layered sheet, graphene ink printed on paper sheet, graphene ink printed on foil sheet, carbon nanotubes placed in contact with a sheet of paper or a sheet of foil, fullerenes placed in contact with a sheet of paper or a sheet of foil, and graphene placed in contact with a sheet of paper or a sheet of foil. In such cases, for example, where the graphene forms one of the outer layers of the laminated sheet, it may be desirable for the graphene layer of the laminated sheet to provide the initial layer of the laminated sheet closest to the element 85 of the substrate. In other cases, such as if there is a laminated graphene foil sheet, it may be desirable in which the foil layer of the laminated sheet provides the initial layer of the laminated sheet closest to the substrate element 85, while the graphene layer acts as a thermal shield between the substrate element 85 and outer wrapping material 75, or the order can be reversed, where the graphene layer is the initial layer of the laminated sheet closest to the substrate element 85, and the foil layer acts as a thermal shield between the substrate element 85 and the outer wrapping material 75. In cases where the wrapping paper 90 contains a heat-conducting layer and a sheet of paper or foil, an insulating layer or a thermal layer can be located between them. 60 In aspects related to the application of, for example, graphene inks, the inks may be applied by various printing methods, such as, for example, gravure printing, flexographic printing, offset printing, screen printing, inkjet printing, or other suitable printing method, to provide different values thickness, pattern, surface coating or composition gradients.

In other aspects, a graphene foil or graphene conductive sheet may be interposed between the cigarette paper (i.e., the outer wrapper material 75) and the aluminum foil (i.e., the foil layer of the sheet associated with the wrapper material 90) to create a paper-graphene-foil layered structure. , covering the outer wrapping material 75 and the wrapping paper 90. In this case, the graphene portion may be completely enclosed (eg, between the inner and outer layers) to prevent or minimize transfer or migration of material therefrom during manufacture and use of the product, which may also prevent or minimize the extraction of glycerin from the substrate element 85 to the outer wrapping material 75. However, it will be apparent to those skilled in the art that the wrapping material 90, which is made to achieve the objectives presented in this application, can be obtained in many different ways in addition to different configurations , which are described in this application, and that these illustrative configurations are not limiting in this respect.

The outer wrapping paper 75 is typically designed to wrap around the heat generating segment 35 and extend longitudinally (further downstream) so as to wrap around the aerosol generating segment 61 and along at least a portion of its length. In addition, being positioned to wrap said components of the smoking article, the outer wrapping paper 75 also extends over the partition between the heat-generating segment 35 and the aerosol-generating segment 61 and thus may also desirably exhibit a lack of burning or susceptibility to minimal burning (as well as a tendency to lack of extraction). Accordingly, in some aspects of the present invention, the outer wrapping paper 75 may be treated or otherwise treated with, for example, calcium carbonate (CaCl), aluminum hydroxide, magnesium hydroxide, and/or combinations thereof as fillers in the paper matrix of outer wrapping paper 75 at least as burn retardants.

Furthermore, it will be apparent to those skilled in the art that opposite ends of wrapping paper 90 and/or outer wrapping material 75 wrapped around respective

Of the components of the smoking article, (that is, the ends overlapping at an angle to each other, which form a seam running in the longitudinal direction along the smoking article) can be connected to each other, for example, by means of an adhesive material. Accordingly, in some aspects of the present invention, the adhesive material may also include a filler, such as calcium carbonate (CaS3), aluminum hydroxide, magnesium hydroxide, and/or combinations thereof, to reduce, minimize, or eliminate burning or charring of the adhesive material and/or the outer wrap material 75 along a longitudinal seam of the outer wrapping material 75 wrapped around the components of the smoking article.

Element 85 of the substrate, forming part of the segment 61, which generates an aerosol, may contain tobacco. In particular, in the case of tobacco content, element 85 of the substrate can be made of a mixture of aromatic varieties of tobacco, for example, in the form of cut filler. These types of tobacco, in turn, can be treated with an aerosol-forming material and/or at least one flavoring agent. The substrate element 85 may be made of processed tobacco (eg, reclaimed tobacco produced by cast sheet or paper processes) in the form of cut filler. Certain cast sheet designs may contain approximately 270 mg to 300 mg of tobacco per 10 mm of cast sheet length. In other cases, the substrate element 85 may contain a mixture of molded tobacco pellets. In some aspects of the present invention, the tobacco substrate element 85 may in turn be treated to contain an aerosol generating material and/or at least one flavoring agent and a flame retardant (e.g., diammonium phosphate or other similar type of salt and/or other suitable flame retardant materials). The inclusion of a flame retardant in the substrate element can be done to prevent ignition of the material forming the substrate and/or to prevent burning of the substrate element caused by the heat-generating element. In addition, the metallic inner layer or surface 96 of the wrapping material/outer layer 94 of the aerosol generating segment 61 may act as a carrier for the aerosol generating material, tobacco components and/or at least one flavoring substance.

The term "tobacco pellets" as used herein includes granules, pellets, or other discrete small particles of tobacco formed, compressed, extruded, or otherwise shaped. For example, tobacco pellets can be formed 60 using a so-called rolling process. Tobacco pellets can have a smooth, regular outer shape (for example, the shape of a sphere, cylinder, oval, etc.) and/or an irregular outer shape. In one example, the diameter of each tobacco pellet may range from about 1 mm to about 2 mm. Tobacco pellets can at least partially fill the chamber of the substrate of the smoking product, as described in this application. In other words, the element 85 of the substrate can take the form of pellets or other free particles that occupy the space inside the segment 61 that generates an aerosol adjacent to the heat-generating segment 35 and located further downstream from it. In one example, the volume of the substrate chamber may be in the range of about 500 mm? to 700 mm3 (eg, the volume of the substrate chamber of a smoking article having a diameter of about 7.5-7.8 mm and a length of about 11 -15 mm having a generally cylindrical shape.) In one example, the mass of tobacco pellets within the substrate chamber may be approximately 200-500 mg. For example, the tobacco pellets may be used to fill a corresponding portion of the aerosol generating segment 61, (for example, the cylindrical region inside its wrapping material, which is limited by the ends of the heat-generating segment 35 and the filtering segment 55) at a density of placement of approximately 100-400 mg/cm3.

The configuration and location of the substrate element 85 may vary according to various aspects of the present invention. In one aspect, the substrate element 85 can be made as a monolithic or integrated structure obtained by, for example, an extrusion molding or casting process. In some preferred aspects, the monolithic substrate element 85 may contain tobacco or tobacco products. For example, in one aspect, the monolithic substrate element 85 formed by the extrusion process may contain glycerin, powdered tobacco, calcium carbonate, a binder, flavor additives, and water. In particular, the extruded material may contain, on a dry weight basis, about 37.86 95 ground tobacco, about 39.82 95 calcium carbonate, about 1.00 95 binder such as carboxymethyl cellulose (CMC) or cellulose resin, and about 21.32 95 glycerin and aromatic additives (where the share of glycerin is approximately 20 95).

The monolithic element 85 of the substrate, formed by the process of extrusion, molding or casting, can have different final shapes and appearances that can contribute to the improvement of heat transfer from the heat-generating segment 35 and/or more

From the efficient distribution of heat to the substrate element 85, rather than to other proximal components of the smoking article, in such a way as to reduce, minimize or eliminate their burning or charring. For example, the extruded element 85 of the substrate may have the shape and configuration of a monolithic grooved rod-like element 300 (see, for example, Fig. 4). In other words, the rod-like element may contain a plurality of protrusions 310, which are angularly spaced around its outer surface, and the adjacent protrusions form open channels 320 that pass between them in the longitudinal direction. In some cases, the grooved rod-like member may also form one or more passages 330 extending longitudinally through its central portion or through one or more protrusions. The location, dimensions and/or configuration of open channels and/or passages may be varied as necessary to obtain specific performance characteristics. For example, one effect of open channels and/or passages is to increase the available surface area compared to a solid cylindrical rod-like element, which in turn leads to increased cigarette burnout (ie, increased lifetime) and reduced pressure drop across the smoking article (ie, to less resistance to tightening).

The effective diameter (ie, maximum outer diameter) of the grooved rod-like member may vary, for example, from about 5.8 mm to 7.3 mm. To include the grooved rod-like member in the aerosol generating segment 61, the larger diameter extrudate may be wrapped with, for example, a laminated sheet of paper-foil or a laminated sheet of paper-foil-paper, while the smaller-diameter extruded material may be wrapped, for example, with a layer of fiberglass mat and then overwrapped with either a laminated paper-foil sheet or a laminated paper-foil-paper sheet prior to wrapping the aerosol generating segment with an outer wrapping material 75 (although any configuration of wrapping material 90 described herein can be carried out if necessary). The increased surface area of the grooved rod-like element results in a smaller surface area of the rod-like element in contact with the wrapping material located between the rod-like element and the outer wrapping material 75, which in turn results in less heat transfer to the outer wrapping material 75 when using smoking products. In addition, the internal passages may provide additional surface area for the rod-like element to be heated by the heat-generating segment and may serve to remove some heat from the end surfaces of the grooved rod-like element (ie, the end portions of the protrusions). In this regard, visible burning of the outer wrapping material 75 can be reduced. In addition, the increased surface area of the grooved rod-like element compared to the solid cylindrical rod-like element, which may be further increased by the additional passage(s), may provide an additional volume (ie, proportional to the surface area of the substrate element 85 ) of aerosol generating material, included in the element 85 of the substrate and exposed to heat from the heat-generating segment 35, as well as reducing the pulling force that must be applied by the user to the smoking product. Accordingly, such a smoking product may have an increased service life compared to a smoking product containing a solid cylindrical substrate element 85.

As an alternative to a laminated sheet of paper-foil or paper-foil-paper forming the wrapping material of the substrate element 85 directly or with a single layer of fiberglass mat located between them, a two-layer sheet of tobacco paper or a three-layer sheet of tobacco paper can be used as the wrapping material. In such cases, if the wrapping material receives heat from the heat-generating segment sufficient to char or burn the wrapping material, the initial layer of the laminated sheet of wrapping material may preferably contain tobacco paper. Thus, burning or charring the tobacco paper layer may impart a tobacco flavor to the resulting aerosol and, accordingly, have little or no adverse effect on the taste or sensory perception of the resulting aerosol. In particular, a tobacco paper, such as a cast sheet or an extruded tobacco paper, can be laminated to a two-layer paper-foil sheet to form a three-layer paper-foil-tobacco paper sheet, where the tobacco paper forms the initial layer of the laminated sheet that is located closest to the substrate element 85 . Such a three-layer configuration can be applied, for example, to both tobacco-containing and non-tobacco-containing elements of the substrate and can, for example, contribute to increased adhesion along the seam formed by wrapping the three-layer sheet around the substrate element (ie, the seam is made between

With tobacco paper and cigarette paper forming the outer layer of the three-layer sheet) and can also add positive aspects to the taste and/or sensory characteristics of the aerosol used by the user. It will be apparent to those skilled in the art upon familiarization with the innovative aspects of the present invention that a three-layer paper-foil-tobacco paper sheet of the type described in this application can also be applied to any tobacco-containing or non-tobacco-containing substrate elements and generating segments. aerosol, which are disclosed in this invention.

In another aspect of the present invention, the substrate element 85 may take the form of a plurality of solid cylindrical rod-like elements 400 (see, for example, Fig. 5) running parallel to each other from the distribution boundary of the heat-generating segment 35 and the aerosol-generating segment 61. Such solid cylindrical rod-like elements can be made using the process of extrusion, molding, or casting if necessary, and can contain, for example, glycerin, crushed tobacco, calcium carbonate, binder, aromatic additives and water. In some cases, the solid cylindrical rod-like member may have a diameter of about 2.9 mm, and a plurality of such rods may be bundled or bundled for insertion into the aerosol generating segment 61 as the substrate member 85 . Precast solid cylindrical rod-like elements can be sequentially wrapped in a similar manner under similar conditions, similar to the configuration of the grooved rod-like element described in this application.

In other aspects, the composition of the material used for the extruded rods, namely, glycerin, ground tobacco, calcium carbonate, binder, flavoring additives and water, can be used to form flat sheets having a thickness of about 0.3 mm to 1.7 mm. In some cases, the sheet may also be extruded (either molded or cast as needed) and then dried to form the substrate material. Then the dried leaf can be destroyed, for example, cut into strips or crushed into pieces. The cut/shredded portions of the formed sheet may be collected and placed in the aerosol generating segment 61 as a substrate element 85 in a similar manner to the cut filler tobacco material (ie, placed instead of the cut filler tobacco material, but in a similar manner).

In some aspects, the substrate element 85 may be made of, for example, cast sheets containing tobacco material. Such cast sheets can be made in a process in which the selected tobacco mixture is cast, dried and cut into strips or crushed into pieces. In some cases, cut strips or crushed pieces of cast sheet may be mixed with other cut fillers (ie, traditional tobacco material in the form of cut filler with or without additional aerosolizer) to provide the desired taste or sensory experience for the user and to facilitate the manufacturing process. In one example, the selected tobacco blend may be characterized as a pectin release blend containing, for example ("on a dry weight basis") about 66.60 95 ground tobacco, about 3.7595 diammonium phosphate, about 4.65 95 ammonium hydroxide, and about 25 95 glycerol and flavorings To treat the mixture to release pectin, ground tobacco, diammonium phosphate, ammonium hydroxide and water can be heated to about 160 "PE (71 degrees Celsius) for about 1.5 hours, for example to improve or enhance sensory qualities of the resulting mixture.

Glycerin and flavoring additives may then be added to the remaining mixture after cooling, which follows the heating step. After that, the resulting mixture can be used to form a cast sheet.

In another example, the selected tobacco mixture may be characterized as a non-ammonized mixture containing, for example, (on a dry weight basis) about 65.62 95 ground tobacco, about 4.50 95 sodium alginate, about 1.13 95 sodium hydroxide or other pH adjuster, about 25 95 glycerin and about 3.75 95 wood pulp. To treat the non-ammonized mixture, the ground tobacco, sodium alginate and water can be heated to about 160" (71 degrees Celsius) for about 1.5 hours, for example to improve or enhance the sensory qualities of the resulting mixture. Then the remaining mixture can be added hydrated wood pulp, binder, glycerine and aromatic additives after cooling, which follows the heating step, and the resulting mixture can then be used to form a cast sheet.

In another example, the selected tobacco blend may be characterized as a tobacco reconstituted material containing, for example, (on a dry weight basis) about 51.895 tobacco pulp, about 4.295 wood pulp, about 22.0 95 concentrated tobacco extract, and about 22.0 95 glycerin and aromatic additives.

From the tobacco-containing reconstituted material, a sheet can be formed using a method similar to the method for a traditional reconstituted sheet. For example, water-soluble elements are first removed from a layer of tobacco pulp, and the remaining tobacco pulp is concentrated to approximately 25-95 percent solids. Wood pulp can then be added to the tobacco pulp to form a base sheet, the density of which can vary from about 120 g/m? up to 240 g/m". Glycerin is then mixed with a concentrated extract of nicotine, which is obtained from tobacco (obasso aegimei pisoyipe, TOM), (for example, in a ratio of 1:1) and added to the base sheet. After that, the formed base sheet can be dried and cut into strips or pieces.Similar to cast sheets, strip or cut reconstituted sheets may be mixed with other cut fillers (eg, traditional tobacco cut filler with or without additional aerosolizer).

In yet another example, the selected tobacco mixture can be characterized as a traditional tobacco material in the form of cut filler with an increased content of glycerin. In such cases, tobacco in the form of cut filler can contain from about 595 to 30 95 of glycerin. The tobacco material in the form of chopped filler with an increased content of glycerin can then be used as the primary substrate (ie, the substrate material forming the substrate element) or can be mixed with the cast sheet material in such a way that the resulting mixture forms the substrate material of the substrate element. Based on the amount of glycerin required or desired, the glycerin may be applied to the tobacco cut filler, for example, as a coating for the cut particles (ie, applied to individual strips of tobacco), as a top coat, or as both. Such tobacco material in the form of chopped filler with an increased content of glycerin can, for example, be mixed with various cast sheets, reconstituted sheets and/or tobacco pellets if necessary to form the substrate material for the substrate element 85. In such cases, where the substrate element 85 has an elevated level of glycerol, it may be desirable to include a wrap of the substrate element 85 that minimizes or eliminates the extraction of the incorporated glycerol onto the outer wrapping material 75.

In yet another example, the selected tobacco-containing mixture may be characterized as a non-tobacco material. For example, a cast sheet used to form a substrate element 60, an extruded substrate element, or a granulated (rolled) substrate element may contain calcium carbonate, rice flour, binder, diammonium phosphate, glycerin, flavoring additives, nicotine (TOM), which is obtained from tobacco and water.

In particular, such a non-tobacco cast sheet may contain, for example, about 41.25 95 calcium carbonate, about 13.75 95 rice flour, about 6 95 ammonium alginate, about 5.595 wood pulp, about 3.595 diammonium phosphate, and about 30 95 glycerin. In addition, nicotine (TOM), which is derived from tobacco, some acids (for example, levulinic acid and/or citric acid) and aromatic additives may be included in glycerin.

An extruded substrate element or a granular (rolled) substrate element may contain, for example, about 51.94 95 calcium carbonate, about 17.1595 rice flour, about 195 TOM, about 195 carboxymethyl cellulose (CMC), about 0.66 95 levulinic acid , about 0.44 95 lactic acid, about 20 95 glycerin, and about 9.4195 aromatics. In some cases, the cast sheet can be converted into cut strips, pieces or presented as a cut filler. In other cases, if the element 85 of the substrate includes granules, they can be located adjacent to the heat-generating segment, adjacent or next to it. In these cases, the selected component can be made opposite the heat-generating segment to secure the pellets in place. For example, such a selected component may include a folded paper filter material or other non-tobacco paper bundle.

In another example, substrate element 85 formed of non-tobacco material, nicotine (TOM), which is derived from tobacco, glycerin (ie, an aerosol former) and flavoring agents may be added to an extruded ceramic substrate of relatively high porosity (ie, a highly porous extruded ceramic rod). In such cases, the ceramic rod may be extruded to form one or more longitudinally extending channels (ie, open channels or grooves located around the outer surface and/or passages that pass through the central portion of the rod element). Similar to the grooved rod example above, the increased surface area of the ceramic rod (ie due to the open channels around its surface) results in a smaller surface area of the rod in contact with

With the wrapping material located between the rod-like element and the outer wrapping material 75, which in turn results in the transfer of less heat to the outer wrapping material 75 when the smoking product is used. In addition, the internal passages may also provide additional surface area for the rod element to be heated by the heat generating segment and may serve to remove some heat from the end surfaces of the grooved ceramic rod element (ie, the end portions of the protrusions). In this regard, visible burning of the outer wrapping material 75 can be reduced. In addition, the increased surface area of the grooved ceramic rod-like element compared to the solid cylindrical rod-like element, which may be further increased by the additional passage(s), may provide an additional volume (ie, proportional to the surface area of the substrate element 85 ) of aerosol generating material , which is included in the element 85 of the substrate and is exposed to the heat from the heat-generating segment 35, as well as reducing the pulling force that must be applied by the user to the smoking product. Accordingly, such a smoking product may have an increased service life compared to a smoking product containing a solid cylindrical substrate element 85. Additionally, open channels/passages may provide less drag resistance.

In some aspects of the present invention, the substrate element 85 may be segmented (ie, the substrate element 85 may contain a plurality of serially arranged components or a plurality of parallelly arranged components) or may contain a combination of two or more substrate materials. For example, the substrate element may comprise a combination of a cast sheet and/or a reconstituted sheet, each of which is shredded or cut into strips, mixed with a glycerine-treated tobacco cut filler.

The tobacco cut filler can have varying levels of glycerine content, for example, in the range of about 5 95 to 25 95. In another example, the cast leaf, which is cut into pieces or cut into strips, can be mixed with tobacco-containing pellets. In addition to wrapping the extruded substrate element with a fiberglass mat, the extruded substrate element 85 may alternatively be wrapped with tobacco paper or a laminated sheet containing a layer of tobacco paper, and the substrate element 85 may contain, for example, a bundle of smaller diameter rod-like elements arranged 60 in parallel, or strips of cast sheet, extruded sheet or reconstituted tobacco sheet which are processed in a manner similar to that applied to tobacco cut filler or rolled together to form a substantially cylindrical substrate element.

In addition to the components described in this application, the substrate element 85 may consist of various combinations of such components. In addition, in some aspects, such components may be further selected from the group consisting, for example, of the following components: a fiberglass mat on which a TOM/glycerol solution (B3) is applied, a porous ceramic element containing an aerosol generator, such as applied on glycerine, cast sheet containing pectin-releasing material, non-ammonized cast sheet, non-tobacco cast sheet, assembled or shredded aerosolized foil sheet or strips made therefrom, and, a non-tobacco product such as assembled paper, that has been treated with an extract such as TOM, pellets or collected carbon or carbonless paper.

The components of the aerosol generating segment may vary. The aerosol generating segment contains components that can be vaporized, aerosolized, or drawn into the air, captured by the flow passing through the smoking product during use. Most preferably, these components individually or in combination provide sensory and organoleptic effects, such as aroma, taste, visible aerosol, etc. Examples of components of the aerosol generating segment that enter the smoker's mouth during inhalation include water (e.g., as water vapor), visible aerosol-forming materials (e.g., glycerin), various volatile flavorings (e.g., vanillin or menthol), volatile tobacco components (for example, nicotine) etc.

A preferred aerosol-forming material forms a visible aerosol when a sufficient amount of heat is applied thereto or otherwise by the action of the aerosol-forming conditions caused by the components of the smoking product. A highly preferred aerosol-forming material produces a visible aerosol that can be viewed as "smoke-like." The preferred aerosol-forming material is chemically simple relative to the chemical nature of the smoke produced by burning tobacco. A preferred visible aerosol-forming material is a polyol, and approximate preferred aerosol-forming materials include glycerin, propylene glycol, and mixtures thereof. If necessary, aerosol-forming materials can be combined with other liquid materials, such as water. For example, chemical compositions

Aerosol-forming materials may include mixtures of glycerol and water or mixtures of propylene glycol and water. See, for example, the various aerosol-forming materials presented in US Patent Nos. 4,793,365 (Zepzaraitsodn, etc.), 5,101,839 (Akoy, etc.) and 8,678,013 (Sgookz, etc.), and also in the international application PCT UMO 98/57556 (Vidoz, etc.).

Materials that can be used to create substrates for aerosol generating materials in aerosol generation areas can vary.

Suitable substrate elements and associated aerosol-forming materials are included in cigarette types marketed under the trademarks Rgetieg, Esiirbze and Zeat

Noah Ope". The substrate element may contain tobacco in some form, typically consists primarily of tobacco, and may be made virtually entirely of tobacco material.

For example, in some embodiments of the invention, at least a portion of the entire substrate material is used essentially in the form of traditional filler (eg, cut filler). Suitable substrate materials and substrate chemistries including aerosol-forming materials (including cast sheet and paper-type recovered tobacco materials) are also described in US Pat. Mo 5,099,861 (Sieaptap, etc.), Mo 5,101,839 (Chako, etc.), Mo 5,105,836 (Sepigu, etc.), Mo 5,109,122 (Sivaptanp, etc.), Mo 5,159,942 (VhipKkiIeu etc.), Mo 5,203,355 (Sivagtap, etc.), Mo 5,271,419 (Aglopiso, etc.), Mo 5,327,917 (I ekmuatsucha, etc.), Mo 5,396,911 (Sazeu, etc.), Mo 5,533,530 (Uoipd, etc.), Mo 5,588,446 (Sivaptap), Mo 5,598,868 (Dako, etc.), Mo 5,715,844 (Uoipa, etc.), Mo 6,378,528 (Veezop, etc.). ) and Mo 8 678 013 (Sgook5 et al.) and publications of US patent applications Mo 2005/0066986 (Meviog et al.), Mo 2012/0067360 (Soppeg et al.) and Mo 2015/0157052 (Adete et al.). In addition, the substrate materials may be of the types or configurations described in US Pat. No. 8,839,799 (Soppeg et al.); in the form of a assembled web or sheet obtained by the methods generally described in US Patent No. 4,807,809 (Rguog et al.), or in the form of a web or sheet that is cut into a plurality of longitudinal threads, which is obtained using methods generally described in US Patent No. 5,025,814 (Kakeg).

The manner in which the aerosol-forming material contacts the substrate material (eg, tobacco material) can vary. The aerosol-forming material may be applied to the formed tobacco material or may be incorporated into the processed tobacco materials in the manufacture of these materials. Aerosol-forming material 60 may be dissolved or dispersed in an aqueous liquid or other suitable solvent or liquid carrier and applied by spraying to said substrate material. See, for example, US Patent Application Publication Mo. 2005/0066986 (Meziog et al.). The amount of aerosol-forming material used relative to the dry weight of the substrate material may vary. Materials containing excessively high levels of aerosol-forming material may prove difficult to process into cigarette rods using traditional types of automated cigarette manufacturing equipment.

Cast sheet materials can have relatively high levels of aerosol-forming material. Reconstituted tobacco produced using the types of papermaking processes may have moderate levels of aerosol-forming material. Filler in the form of tobacco strips and cut tobacco may contain a smaller amount of aerosol-forming material. Various paper and non-paper substrates can be used within the scope of the invention, including assembled, multilayer, multilayer metal, strips, granules, for example, aluminum oxide granules, open-cell foam, foamed monolith, air-permeable matrices and other materials. See, for example, US Patent Nos. 5,183,062, 5,15,203,355, and 5,588,446 (US Patent No. 5,588,446).

Laminated paper or other wrapping material may be made as described in US Pat. No. 8,49,085 (Magpop) or by other suitable methods and/or materials.

In some preferred smoking products, both ends of the aerosol generating segment 61 are open to provide access to the substrate element 85. Together, the heat-generating segment 35 and the aerosol-generating segment 61 form the aerosol-generating system 99 .

The aerosol generating segment is located adjacent to the downstream end of the heat generating segment such that these segments are axially aligned end to end. These segments can be adjacent to each other or can be located at a short distance from each other, which can include, if necessary, a buffer region 110 (which in some cases can contain a heat-conducting air-permeable partition element). The external cross-sectional shape and dimensions of these segments, when viewed perpendicular to the longitudinal axis of the smoking article 10, may be essentially the same as each other. The physical arrangement of these components is preferably such that heat is transferred (e.g., by mechanisms involving conductive and convective heat transfer) from the heat source 40 to the adjacent substrate element 85 throughout the duration of operation (e.g., burning) of the heat source during use of the smoking article 10 .

The buffer region 110 may reduce the possibility of burning or other thermal decomposition of portions of the aerosol generating segment 61. The buffer region may primarily comprise an empty cavity, or it may be partially or substantially completely filled with a non-combustible material, such as, for example, metallic, organic, inorganic, ceramic, or polymeric materials, or any combination thereof. The length (thickness) of the buffer region can be about 1-10 mm, however, is often about 2-5 mm. If necessary, the buffer region or partition segment 110 may contain catalytic materials, such as materials including cerium or copper ions or oxides and/or salts of cerium and copper ions. See, e.g., US Patent Nos. 8,469,035 (Wapegie et al.) and 8,617,263 (Wapegiee et al.), and US Patent Application Publication No. 2007/0215168 (Wapegiee et al.).

The components of the aerosol generating system 99 are preferably connected to each other and secured in place by a wrapping material 118. For example, the wrapping material may include a paper wrapping material or a multi-layered paper material that surrounds a portion of the heat generating segment 35 located further back flow, and at least part of the outer surface of the segment 61 generating the aerosol, which passes in the longitudinal direction. The inner surface of the wrapping material 118 may be attached to the outer surfaces of the components it surrounds with a suitable adhesive. It will be apparent to those skilled in the art that aspects disclosed in this application to reduce, minimize, or eliminate burning or charring of the outer wrapping material 75 or wrapping paper 90 may also be applicable to the wrapping material 118 in cases where the wrapping material the material 118 overlaps the outer wrapping material 75 or passes over the boundary of the distribution between the heat-generating segment 35 and the aerosol-generating segment 61 .

In a preferred embodiment of the invention, the smoking product 10 includes a suitable mouthpiece, such as, for example, a filter element 135 located at the mouthpiece end 18 of the product. The filter element 135 is preferably located at one end of the aerosol generating system 99 so that the filter element 135 and the aerosol generating segment 99 are axially aligned end to end, adjacent to each other, in the absence of a barrier between them. In a preferred embodiment of the invention, the general cross-sectional shape and dimensions of said segments 99, 135 are essentially the same when viewed perpendicular to the longitudinal axis of the smoking product. The filter element 135 may contain a filter material 140 wrapped along its longitudinal surface with the surrounding material 142 ficel. In one example, the filter material 140 comprises a tow of plasticized cellulose acetate fiber or other suitable cigarette-type filter material. Both ends of the filter element 135 are preferably open to allow aerosol to pass through. In some cases, the filter element 135 can be made with the possibility of containing any combination of paper tow, cavity, and traditional cigarette filter material (eg, cellulose acetate fiber tow) as needed.

In addition, the filter element can contain a destroyed aromatic capsule, the type of which is described in US patents Mo 7,479,098 (Tpotaz et al.), Me 7,793,665 (Oibe et al.) and Mo 8,186,359 (Adete et al.).

The aerosol generating system 99 is preferably attached to the filter element 135 by a rim paper 150. Examples of rim paper are described, for example, in U.S. Pat.

US Patent No. 7,789,089 (Oibe et al.), US Patent Application Publications No. 2007/0215167 (StookK5 et al.), No. 2010/0108081 (Douse et al.), No. 2010/0108084 (Mogtap et al.) and No. 2013 /0167849 (Adete et al.) and publication of the international patent application No. 2013/160671 (Ringisy et al.).

The smoking article 10 may contain a dilution agent, such as a series of perforations 160 , each of which may pass through the rim paper 150 of the filter element and the fissile material 142 . In an alternative embodiment of the invention, various perforation holes can pass around the smoking product as a ring in an area that is located earlier in the flow compared to the one shown.

The length of a typical smoking article 10 is approximately 80 mm to 100 mm.

For example, for a smoking article 10 that is approximately 85 mm in length, a typical heat generating segment 35 may be approximately 10 mm to 15 mm in length, a typical aerosol generating segment 61 may be approximately 40 mm to 55 mm in length, and a typical filter element 135 may be approximately 20 mm to 30 mm in length.

Of the Cigarettes described with reference to fig. 1, can be used in much the same way as cigarettes produced under the trademarks "Rgetieg" and "Esiirhe" by the tobacco company K. U. Keupoid5 Thorasso Sotrapu and produced under the trademark "Bivat Noi

Ope" by tobacco company darap Tobasso Ips. In other words, the fuel element or heat source is ignited with a match or cigarette lighter. The burning fuel element/heat source resulting from such ignition produces heat that is transferred to the substrate element in the region that generates an aerosol, cigarettes. The substrate element(s), including aerosol-forming materials, as well as flavorings and components, are heated and vaporized to form an aerosol. This aerosol is captured by inhaled air and carried through the filter element into the smoker's mouth.

In fig. 2 illustrates another typical smoking article 10 in the form of a cigarette in accordance with another aspect of the invention. In a preferred embodiment of the invention, the smoking article 10 has the general size, shape and general appearance of the smoking article described above with reference to FIG. 1, and also includes the types of components that are similar to the types of components of the smoking product shown in Fig.1. However, in comparison with the variant presented in fig. 1, the length of the filtering segment 135 is increased and the length of the aerosol generating segment 61 is reduced. For example, for the shown embodiment of the invention, the filter element 135 is a two-component segment that includes an extreme mouthpiece end segment 182 and a tubular segment 184 located between the aerosol generating segment and the extreme mouthpiece end segment. Thus, the typical smoking product shown in FIG. 2 is a four-segment smoking product, while the typical smoking product shown in FIG. 1, is a three-segment smoking product.

Typically, the tubular segment 184 includes a tube that is made of plasticized cellulose acetate fiber, steam treated, which provides elasticity, structure and length of the smoking article, while allowing the passage of drawn air through it. Alternatively, the tubular segment is made of a heat-resistant plastic material (for example, a tube made of polycarbonate) or a ceramic material.

The length of the typical smoking product 10 shown in Fig. 2, is approximately 80 mm to 100 mm. For example, for a smoking article 10 that is approximately 60 to 85 mm in length, a typical heat generating segment 35 may be approximately 10 mm to 15 mm in length, a typical aerosol generating segment 61 may be approximately 10 mm to 25 mm in length, a typical tubular segment 184 may be approximately 30 mm to 50 mm in length and a typical filter element 135 may be approximately 20 mm to 30 mm in length.

In fig. 3 shows another typical smoking article 10 in the form of a cigarette. In a preferred embodiment of the invention, the smoking product 10 has the general size, shape, and general appearance of the smoking product described above with reference to FIG. 2, and includes component types similar to the component types of the smoking product shown in FIG. 2. However, between the aerosol-generating system 99 and the filter element 135, there is a tobacco segment 198 made of tobacco cut filler 200 and wrapped with a paper wrapping material 205. Compared to the embodiment of the invention presented in Fig. 2, the general the length of the two-component filter segment is reduced to accommodate a segment made of tobacco cut filler. Thus, a typical smoking product shown in fig. 3 is a five-segment smoking product, while the typical smoking product shown in FIG. 2, is a four-segment smoking product.

The upstream segment of the two-component filter segment 135 may consist of a hardened tube made of a tow of cellulose acetate fiber, in which activated carbon particles are dispersed and a destructive aroma capsule is located, etc. Typically, the downstream segment of the two-component filter segment 135 is a segment that is made of plasticized cellulose acetate fiber tow or assembled polypropylene fabric. If necessary, the two-component filter segment can be replaced by a single-component filter element or a three-chamber filter.

The length of the typical smoking product 10 shown in Fig. 3, is approximately 80 mm to 100 mm. For example, for a smoking article 10 that is approximately 85 mm in length, a typical heat generating segment 35 may be approximately 10 mm to 15 mm in length, a typical aerosol generating segment 61 may be approximately 10 mm to 25 mm in length, a typical segment The tobacco filler 198 may have a length of about 30 mm to 50 mm and the typical filter element 135 may have a total length of about 20 mm to

From 30 mm. For a typical filter element in the present embodiment, the upstream segment 220 of the filter element may have a length of approximately 5 mm to 20 mm, and the downstream segment 225 of the filter element may have a length of approximately 5 mm to 20 mm. For example, a typical smoking article having an overall length of approximately 83 mm may include a heat generating segment 35 approximately 12 mm long, an aerosol generating segment 61 approximately 13 mm long, a tobacco filler segment 198 approximately 37 mm long, a cellulose acetate tube filter segment 220 approximately 7 mm long and segment 225 of low performance plasticized cellulose acetate fiber tow approximately 14 mm long.

In addition, typical smoking products contain various components related to their construction.

For example, these types of components include wrapping materials, thermally conductive materials, metal foils and foil layers, mouthpieces, filter elements, fizels, wrapping paper, and adhesives. In addition, typical smoking products may contain a wide variety of tobacco types, types of tobacco, and mixtures thereof. Such typical components, for example, are presented in US patents Mo 5,724,997 (Rada et al.), Mo 8,678,013 (Stooks et al.) and patent application publications

US Mo. 2015/0157052 (Adete et al.).

Various combinations and varieties of flavoring agents (including various materials that alter the sensory and/or organoleptic character or nature of the primary inhalable aerosol of the smoking product) may be incorporated into suitable smoking products. The substrate material and the various tobacco components of the smoking product may be treated with tobacco additives of the type traditionally used in the manufacture of cigarettes, for example, sleeve and/or surface layer components. See, for example, the types of components presented in US Patent No. 8,678,013 (Stgookz et al.).

Methods and methods of assembling typical smoking products are described in US patents Mo 5,469,871 (Vagpez et al.) and Mo 8,678,013 (Sgookz5 et al.), as well as in US patent application publications Mo 2012/0042885 (ope et al.) , Mo 2012/0067360 (Soppeg and others), Mo 2014/0261470 (Ativ5 and others) and Mo 2015/0157052 (Adete and others).

In light of the possible interrelationship between the aspects of the present invention in providing the specified values and advantages associated therewith, the present invention thus particularly and expressly includes, without limitation, embodiments of the invention representing various combinations of the disclosed aspects Thus, the present invention includes any combination of two, three, four or more features or elements set forth in this description of the invention, regardless of whether such features or elements are combined in an explicit form or otherwise set forth in a particular embodiment of the invention , which is described in this application. This description is intended to be read with all elements taken into account such that any individual features or elements of the described invention in any of its various aspects and embodiments are to be considered combined unless the context of the description of the invention clearly dictates otherwise.

Aerosols produced by cigarettes in accordance with the present invention are aerosols comprising air-containing components such as vapor, gases, suspended solids, and the like. Aerosol components can be obtained by burning tobacco of any kind (and, if necessary, other components that burn to generate heat); by thermally decomposing the tobacco caused by heating the tobacco and charring the tobacco (or otherwise subjecting the tobacco to decay in some form); and by evaporation of an aerosol-forming substance. In this regard, the aerosol may contain vaporized components, combustion products (eg, carbon dioxide and water), incomplete combustion products, pyrolysis products, and aerosols, which are further described as smoke.

In addition, aerosol components can be produced by the effect of heat from burning tobacco of any kind (and, if necessary, other components burning to generate heat) on substances that are in thermal interaction with the burning tobacco material and other burning components. Aerosol components can also be produced by the aerosol generation system as a result of the effect of the heat-generating segment on the aerosol-generating segment. In some embodiments of the invention, the components of the aerosol generating segment have such a general composition and are located in the smoking product in such a way that these components do not undergo significant thermal degradation (eg, as a result of combustion, smoldering or pyrolysis) under conditions of normal use.

Many modifications and other aspects of the invention set forth in this application may be apparent to those skilled in the art after reading the above description and accompanying drawings. For example, specialists in this field of technology understand that

Of the variants of implementation of the invention, which are not presented in an explicit form in this application, can be realized within the scope of this invention, and also that the characteristics described in this application for different variants of the invention can be combined with each other and/or with technical solutions known at present or developed in the future within the scope of the claims presented in this application. In some such aspects, for example, conditions may be implemented to reduce, minimize, or eliminate burning, charring, or discoloration of the outer wrapping material, such as using an embossed wrapping material (e.g., made of paper) as an additional layer of the outer wrapping material (e.g., cigarette paper). In such cases, an increased surface area is provided by embossing, and/or the embossed wrapping material, at least partially spaced from the outer wrapping material, may provide for the use of the wrapping material as an external air-cooling device (e.g., cooling fins). In other cases, various measures shall be taken to provide visual indications of overheating or elevated temperature.For example, thermochromic inks may be applied to the embossed wrapping material and/or outer wrapping material, which visually manifest or change appearance when a temperature threshold is exceeded or within a specific temperature range, and/or disappear below a temperature threshold or within a specific temperature range.Thus, for example, the user may be advised to refrain from using the smoking product in extreme temperature conditions until the indication provided by the thermochromic ink changes its an appearance indicative of the appropriate temperature of the smoking product, and such measure may prevent use at an excess temperature which would result in burning or charring of the outer wrapping material or any other component exposed to the heat produced by the heat-generating segment. In other cases, the outer wrapping material 75 or the wrapping paper/material 90 may contain or have associated therewith a non-woven graphite or graphene sheet as a thermally conductive element or otherwise dissipate excess heat away from the outer wrapping paper 75. In other words, the non-woven graphite or graphene sheet may be wrapped around a portion of the heat generating portion and around portion 60 of the aerosol generating portion, within the outer wrapping material and extending toward the mouthpiece end portion.

Thus, it should be understood that the present invention is not limited to the specific aspects described in this application, and that equivalents, modifications, and other aspects are included within the scope of protection of the present invention as defined by the appended claims. Although specific terms are used in this application, they are used only in a generic and descriptive sense and not for the purpose of limitation. Aspects of the present invention are more fully illustrated in the examples provided herein, which are presented to illustrate certain aspects of the present invention and should not be construed as limiting its scope. Unless otherwise noted, all parts and percentages are by weight.
