    专利说明:

    [0001] The present invention relates to rods comprising a sheet of aerosol-forming material and a sheet of a thermally conductive material, wherein the sheets are being grouped to form a rod for use in aerosol-generating articles. The present invention also relates to aerosol-generating articles comprising such rods, and methods for forming such rods.
    [0002] The processes and apparatus for producing scraps, cords or strips of tobacco material are known in the art. Typically, the width of such flaps, cords and strips of tobacco material is about 3 mm or less.
    [0003] For example, patent document US-A-4,000,748 discloses a process and apparatus for shredding a tobacco leaf reconstituted into strips and crimping the resulting strips in a substantially simultaneous operation. The sheet of tobacco material is moved between a pair of piles of rotating discs and interspersed which cut the sheet into a plurality of strips about 0.65 to 1.55 mm wide. The forward movement of the resulting strips is slowed by coupling with the coating surfaces of neighboring discs that cause the strips to curl in a crimped configuration. Beaded strips are considered to provide an increase in weft value.
    [0004] The formation of rods for aerosol-generating articles that comprise flaps of beaded or non-beaded tobacco material suffers from a number of disadvantages, including those discussed below.
    [0005] First, the shredding of tobacco material generates undesirable fines of tobacco and other waste.
    [0006] Secondly, rods that comprise pieces of tobacco material exhibit 'loose ends'. That is, there is a loss of tobacco material flaps from the ends of the rod. This is exacerbated by the rupture of flaps of tobacco material during the formation of the rod. Loose ends are not only aesthetically undesirable, but they can also disadvantageously lead to the need for more frequent cleaning of manufacturing equipment and aerosol generating devices. The problem of loose ends is particularly exacerbated in aerosol-generating articles, because the length of the rod of the aerosol-generating substrate tends to be short compared to conventional cigarettes and, therefore, the proportion of substrate material that is in the vicinity of an end is bigger.
    [0007] Third, rods that comprise flaps of tobacco material exhibit large standard deviations in weight. That is, rods of the same dimensions tend to be of inconsistent weight. This is partly due to the rods' tendency to exhibit loose ends as mentioned above. The large standard deviation in the weight of rods that comprise flaps of tobacco material leads to an undesirably high rate of rejection of rods whose weight falls outside a selected acceptance range. In addition, rods that comprise patches of tobacco material exhibit non-uniform densities. That is, the density along the length of the rod tends to be inconsistent. This is due to variations in the amount of tobacco material at different locations along the rod, which results in 'empty spaces', which are regions that have reduced amounts of tobacco material, and 'cushions', which are regions that have higher levels of tobacco material. The non-uniform density of rods that comprise flaps of tobacco material can undesirably affect rod extraction resistance (RTD). In addition, the uneven density of rods that comprise flaps of tobacco material can lead to loose ends when an empty space is located at the end of the rod.
    [0008] Loose ends, large standard deviations from weight, and non-uniform densities as exhibited by rods comprising flaps of tobacco material are particularly problematic and undesirable in short rod length rods. Short rod length rods are sometimes referred to as plugs.
    [0009] Patent document EP-A1-2 062 484 discloses a process for forming smokeless tobacco articles for oral consumption. A reconstituted tobacco leaf is grouped on a stick, rolled and cut into pieces suitable for oral consumption.
    [00010] It would be desirable to provide rods that comprise tobacco material for use in aerosol-generating articles.
    [00011] A rod comprising a first sheet comprising an aerosol forming material and a second sheet comprising a thermally conductive material, wherein the first and second sheets are grouped and circumscribed by a wrap.
    [00012] The grouped sheets of material preferably extend substantially over the entire length of the rod and substantially across the entire cross-sectional area of the rod.
    [00013] The first sheet comprising a tobacco material may be a sheet of reconstituted tobacco or homogenized tobacco, preferably a sheet of reconstituted tobacco or homogenized tobacco comprising a proportion of an aerosol former.
    [00014] The second sheet comprising a non-tobacco flavoring may be a non-tobacco sheet such as a polymer sheet or a sheet of paper or a metallic sheet. In some embodiments, the second sheet may comprise a material selected from the group comprising a metal sheet, a polymer sheet, and a substantially non-porous paper or cardboard. In some embodiments, the second sheet may comprise a material selected from the group consisting of polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), polylactic acid (PLA), cellulose acetate (CA), starch-based copolyester, and aluminum foil.
    [00015] The second sheet can be coated with the non-tobacco flavoring. The second leaf can be impregnated with the non-tobacco flavoring.
    [00016] The second sheet can be formed from a material such as a gel or a hydrogel that incorporates the flavoring. The second leaf can volatilize under heating to release the flavoring agent. The second sheet may comprise a biodegradable polymer, for example, the second sheet may be a sheet of polylactic acid (PLA) that is coated or impregnated with a flavoring agent.
    [00017] The flavoring agent may comprise a volatile aroma component. The flavoring agent can comprise menthol. As used herein, the term 'menthol' refers to the compound 2-isopropyl-5-methyl cyclohexanol in any of its isomeric forms. The flavoring can give an aroma selected from the group consisting of menthol, lemon, vanilla, orange, wintergreen, cherry and cinnamon.
    [00018] The second sheet comprising a non-tobacco flavoring agent may also comprise an aerosol former such as glycerin. The aerosol former may contain aroma components in an aerosol.
    [00019] To modify the aroma of mainstream smoke from a conventional cigarette, it is known to employ single-segment and multiple-strand nozzle filters that include flavorings, such as menthol. Menthol can be incorporated into the filter, the rolled tobacco rod or the aerosol-generating substrate of cigarettes in liquid substrate form by using an appropriate liquid carrier. Liquid forms of menthol are volatile and therefore tend to migrate or evaporate during storage and flavor tobacco in cigarettes. Alternatively, menthol or other flavoring can be incorporated into a cigarette as a strip, a granule, or other means.
    [00020] During the consumption of a conventional cigarette, a combustion line passes through the cigarette. The menthol that has migrated to tobacco is released as the combustion line passes. On the other hand, heated aerosol-generating articles typically function by distilling volatile compounds from an aerosol-forming substrate. Much of the substrate is heated at the same time and volatile compounds are evolved. Due to the fact that flavor additives such as menthol are highly volatile, they tend to be evolved and consumed earlier than other elements in the substrate. Unless the charge of menthol or aroma in the article is high, the taste decreases rapidly as the article is consumed.
    [00021] Although the impregnation of menthol in a conventional cigarette is well known, the application of a menthol aroma, or other flavor, to an aerosol-generating article may not be direct. Filters that are typically used in aerosol-generating articles are shorter than filters used in conventional cigarettes. In addition, the amount of tobacco in aerosol-generating articles is less than in a conventional cigarette. This can reduce the maximum menthol charge that is possible compared to a conventional cigarette.
    [00022] An aerosol-forming substrate in an aerosol-generating article is typically a processed substrate that contains an aerosol-former such as glycerin. For example, it may be possible to form an aerosol-forming substrate for an aerosol-generating article from a folded tobacco plug comprising molded sheet or reconstituted tobacco. A flavoring agent, such as menthol, can be incorporated into the aerosol-forming substrate. However, the structure of the aerosol-forming substrate may be compromised as a result of this incorporation. For example, the menthol charge in a molded tobacco can reduce the density and strength of molded sheet tobacco, which makes it less suitable for use as an aerosol-forming substrate in an aerosol-generating article. For example, it may be difficult to form a plug from a molded tobacco leaf that has insufficient strength due to the presence of a flavoring in the leaf.
    [00023] A rod comprising a tobacco leaf and a separate leaf comprising a non-tobacco flavoring may be particularly advantageous for use as an aerosol-forming substrate of an aerosol-generating article. Once the flavoring is comprised on a separate tobacco leaf, the structural integrity of the tobacco leaf is not compromised.
    [00024] Preferably, the first sheet and the second sheet are of similar dimensions, for example, the sheets are preferably of a similar or identical width. Preferably, the first sheet and the second sheet are arranged in an overlapping relationship prior to bundling on the rod. Thus, the flavoring charge on the stick is relatively high. The flavoring and tobacco are evenly distributed throughout the rod. A cross section taken at any point along the length of the rod will have the same proportion as the first sheet to the second sheet.
    [00025] The formation of a rod as described in the present invention can have additional advantages. It is straightforward to change the flavoring sheet to produce a product that has a different aroma in the same manufacturing line. Due to the fact that the flavoring is on a separate tobacco leaf, it is possible to produce small batches of certain flavored products in an economical way.
    [00026] As used in the present invention, the term 'rod' is used to refer to a generally cylindrical element of substantially circular, oval or elliptical cross-section.
    [00027] As used in the present invention, the term 'sheet' refers to a laminar element that has a width and length substantially greater than its thickness. The width of a sheet is greater than 10 mm, preferably greater than 20 mm or 30 mm.
    [00028] As used in the present invention, the term "aerosol forming material" refers to a material that can release volatile compounds with heating to generate an aerosol. Tobacco can be classified as an aerosol forming material, in particular a homogenized tobacco leaf comprising an aerosol former. An aerosol-forming substrate may comprise or consist of an aerosol-forming material.
    [00029] As used in the present invention, the term 'rod length' refers to the dimension towards the cylindrical axis of the rods as described in the present invention.
    [00030] As used in the present invention, the term 'homogenized tobacco material' refers to a material formed by the agglomeration of particulate tobacco.
    [00031] As used in the present invention, the term 'clustered' denotes that the sheet of tobacco material is rolled, folded, or compressed or constricted in ways substantially transversal to the cylindrical axis of the rod.
    [00032] As used in the present invention, the terms 'upstream' and 'downstream' are used to describe the relative positions of the components, or parts of components, of the aerosol generating articles comprising the rods as described herein invention with respect to the direction of the air drawn through the aerosol generating articles during their use.
    [00033] A rod formed from a grouped leaf comprising tobacco material and a second leaf comprising a non-tobacco flavoring may be particularly advantageous as a component of an aerosol-generating article, in particular an aerosol-generating article heated.
    [00034] Heated aerosol generating systems operate by heating an aerosol-forming substrate to generate an aerosol from the substrate material. The aerosol can then be inhaled by a consumer. In heating a substrate comprising rods formed as described in the present invention, tobacco flavors are evolved from the tobacco material sheet and non-tobacco flavors are evolved from the sheet comprising the non-tobacco flavor. The inhalable aerosol formed by heating the substrate comprises a proportion of aerosol components derived from the tobacco leaf and a proportion of aerosol components derived from the leaf comprising a non-tobacco flavor.
    [00035] The first sheet comprising the tobacco material can be a sheet of textured material. The use of a sheet of textured material can advantageously facilitate the grouping of the sheet to form a rod as described in the present invention. The second sheet comprising the non-tobacco flavoring material may be a sheet of textured material. The first and second sheets of material can be sheets of textured material.
    [00036] As used in the present invention, the term 'textured sheet' refers to a sheet that is crimped, shaped, roughened, perforated or otherwise deformed. Textured sheets of material, such as homogenized tobacco, can comprise a plurality of cutouts, protrusions, perforations separated from each other, or a combination thereof.
    [00037] According to a particularly preferred embodiment, a rod is provided which comprises a crimped sheet of aerosol-forming material and a sheet of thermally conductive material, in which the sheets are grouped and circumscribed by a wrap.
    [00038] As used in the present invention, the term 'crimped sheet' lends itself to be synonymous with the term 'crepe sheet' and refers to a sheet that has a plurality of substantially parallel ridges or corrugations. Preferably, a crimped sheet of aerosol-forming material, for example, a crimped sheet of homogenized tobacco material, has a plurality of ridges or corrugations substantially parallel to the cylindrical axis of the rod according to the specification. This advantageously facilitates the grouping of the crimped sheet of aerosol-forming material to form the rod. However, it should be appreciated that the crimped sheets of aerosol-forming material may alternatively or additionally have a plurality of substantially parallel ridges or corrugations arranged at an acute or obtuse angle with respect to the cylindrical axis of the rod.
    [00039] In certain embodiments, sheets of material for use in forming rods as described in the present invention can be substantially uniformly textured over substantially the entire surface. For example, the crimped sheets of material for use in forming rods as described in the present invention can comprise a plurality of substantially parallel ridges or corrugations that are separated from each other substantially uniformly across the width of the sheet.
    [00040] A rod as described in the present invention can comprise one or more additional sheets of material grouped with the first and second sheets to form the rod. Any additional sheet or sheets can be textured, for example, crimped before retraction. Any additional leaf or leaves may comprise additional aerosol forming materials, such as one or more additional sheets of homogenized tobacco.
    [00041] As described in the present invention, there is also disclosed the use of for use of a rod as described in the present invention as an aerosol forming substrate in an aerosol generating article.
    [00042] As described in the present invention, there is also disclosed an aerosol generating article comprising a rod as described in the present invention.
    [00043] A series of aerosol-generating articles in which an aerosol-forming substrate is heated and not burned has been proposed in the state of the art. Typically in heated aerosol-generating articles, an aerosol is generated by transferring heat from a heat source, for example, a chemical, electrical or combustible heat source, to a physically separate aerosol-generating substrate, which can be located inside, around or downstream of the heat source.
    [00044] As used in the present invention, the term 'aerosol generating substrate' refers to a substrate consisting of or comprising an aerosol-forming material that can release volatile compounds with heating to generate an aerosol.
    [00045] Rods as described in the present invention are particularly suitable for use as aerosol forming substrates for heated aerosol generating articles. Aerosol-forming substrates in heated aerosol-generating articles are typically significantly shorter in rod length than sticks of combustible smokeable material in conventional light-ended smoking articles. As noted above, the loose ends, the high non-uniform densities that are exhibited by the rods that comprise flaps of tobacco material are particularly undesirable in the rods of aerosol-generating material that have a short rod length. The use of short rods as described in the present invention as aerosol-generating substrates in heated aerosol-generating articles advantageously minimizes or avoids one or more of the disadvantages associated with the use of the short rods that comprise the flaps of tobacco material discussed previously. above.
    [00046] In one embodiment, rods as described in the present invention can be used as aerosol-forming substrates in heated aerosol-generating articles comprising a combustible heat source and an aerosol-generating substrate downstream of the combustible heat source.
    [00047] For example, rods as described in the present invention can be used as aerosol-generating substrates in heated aerosol-generating articles of the type shown in patent document WO-A-2009/022232, which comprise a heat source based on combustible carbon, an aerosol generating substrate downstream of the combustible heat source, and a thermally conductive element around and in contact with a rear part of the combustible carbon based heat source and an adjacent front part of the substrate aerosol generator. However, it should be appreciated that rods as described in the present invention can also be used as aerosol-generating substrates in heated aerosol-generating articles that comprise combustible heat sources that have other constructions.
    [00048] In another embodiment, rods as described in the present invention can be used as aerosol-generating substrates in heated aerosol-generating articles for use in electrically operated aerosol-generating systems in which the aerosol-generating substrate of the generating article heated aerosol is heated by an electric heat source.
    [00049] For example, rods as described in the present invention can be used as aerosol-generating substrates in heated aerosol-generating articles of the type shown in patent document EP-A-0 822 670.
    [00050] A system comprising an electrically operated aerosol generating apparatus and an aerosol generating article for use with the apparatus may be provided. The aerosol-generating article comprises a rod or an aerosol-forming substrate as described in the present invention.
    [00051] The insertion and removal of heated aerosol-generating articles from an electrically operated aerosol-generating system, for example, an electrically heated aerosol-generating system, in which those articles include a rod comprising flaps of tobacco material, tends dislodging the tobacco material scraps from the rod. This can disadvantageously result in the need for more frequent cleaning of the electrical heat source and other parts of the electrically operated aerosol generating system in order to remove the dislodged flaps.
    [00052] On the other hand, the insertion and removal of heated aerosol-generating articles including an aerosol-generating substrate comprising a rod as described in the present invention is less likely to result in displacement of the tobacco material. As described in the present invention, there is also provided a filter for a smoking article or an aerosol generating article, wherein the filter comprises a rod as described in the present invention. The rods as described in the present invention can be used in the filters for both aerosol generating articles with a lighted end, such as conventional smoking articles, and heated aerosol generating articles. Rods as described in the present invention can be used on filters that comprise a single filter segment. Rods as described in the present invention can also be used in multi-component filters that comprise two or more filter segments.
    [00053] Filters comprising filter segments containing tobacco are known in the art. For example, patent document EP-A-1 889 550 discloses a multi-component filter for a smoking article comprising: a segment of the mouth end; a first flavor-releasing segment comprising tobacco or leaf from another plant upstream of the end-of-mouth segment; and a second flavor release segment comprising the filtration material and a flavorant upstream of the first flavor release segment. The extraction resistance of the second flavor releasing segment is greater than the extraction resistance of the first flavor releasing segment and the extraction resistance of the second flavor releasing segment is greater than the extraction resistance of the end segment from the mouth.
    [00054] In certain embodiments, rods as described in the present invention can be used as filter segments containing tobacco in single or multi-component filters. For example, rods as described in the present invention can be used as a first flavor releasing segment in multi-component filters of the type shown in patent document EP-A-1 889550.
    [00055] Filters comprising rods as described in the present invention can also comprise one or more filtration materials for the removal of particulate components, gaseous components or a combination thereof. Suitable filtration materials are known in the art and include, but are not limited to: fibrous filtration materials such as, for example, cellulose acetate tow and paper; adsorbents such as, for example, activated alumina, zeolites, molecular sieves and silica gel; and their combinations.
    [00056] Preferably, the rods according to the specification are substantially uniform in cross section.
    [00057] Rods can be produced according to the specification that have different dimensions depending on their intended use.
    [00058] For example, rods according to the specification can have a diameter between about 5 mm and about 10 mm, depending on their intended use.
    [00059] For example, rods according to the specification can have a rod length between about 5 mm and about 150 mm, depending on their intended use.
    [00060] In the preferred embodiments, the rods according to the specification for use as aerosol forming substrates in heated aerosol-generating articles can have a rod length between about 5 mm and about 20 mm or about 30 mm .
    [00061] In other embodiments, rods according to the specification for use in filters for conventional light-ended smoking articles and heated aerosol-generating articles can have a rod length between about 5 mm and about 30 mm .
    [00062] Rods according to the descriptive report of a desired single rod length can be produced by forming a multiple single rod length rod and then the multiple single rod length rod is cut and divided into multiple rods desired rod length.
    [00063] For example, rods having a rod length of about 15 mm for use as aerosol-forming substrates in heated aerosol-generating articles can be produced by forming a rod that has a rod length of about 150 mm and then the elongated rod is divided into ten rods that have a rod length of about 15 mm.
    [00064] Preferred embodiments comprise sheets of homogenized tobacco material. The sheets of homogenized tobacco material can be formed by agglomerating the particulate tobacco obtained by grinding or grinding, or both, of tobacco leaf blades and tobacco leaf stalks. Alternatively, or in addition, the tobacco leaves of the homogenized tobacco material may comprise one or more of tobacco dust, tobacco fines and other by-products of particulate tobacco formed during, for example, treatment, handling and transportation tobacco. Where rods according to the specification are suitable for use as aerosol-forming substrates in heated aerosol-generating articles, the sheets of homogenized tobacco material used to form rods preferably comprise particulate tobacco obtained by grinding or else crushing tobacco leaf blades.
    [00065] In certain embodiments, sheets of homogenized tobacco material may have a tobacco content of at least about 40% by weight on a dry weight basis or at least about 50% by weight on a weight basis dry. In other embodiments, sheets of homogenized tobacco material may have a tobacco content of about 70% or more by weight on a dry weight basis. Where rods according to the specification are suitable for use as aerosol-forming substrates in heated aerosol-generating articles, the use of homogenized tobacco material sheets that have high tobacco content advantageously generates aerosols with enhanced tobacco flavor.
    [00066] The sheets of homogenized tobacco material may comprise one or more intrinsic binders, that is, endogenous tobacco binders, one or more extrinsic binders, that is, exogenous tobacco binders, or a combination thereof to help agglomerate the tobacco particulate. Alternatively, or additionally, sheets of homogenized tobacco material may comprise other additives including, but not limited to, tobacco and non-tobacco fibers, aerosol builders, humectants, plasticizers, flavorings, fillers, aqueous and non-aqueous solvents , and their combinations.
    [00067] Extrinsic binders suitable for inclusion in sheets of homogenized tobacco material for use in forming a rod as described in the present invention are known in the art and include, but are not limited to: gums such as , for example, guar gum, xanthan gum, arabic gum and locust bean gum; cellulosic binders such as, for example, hydroxy propyl cellulose, carboxy methyl cellulose, hydroxy ethyl cellulose, methyl cellulose and ethyl cellulose; polysaccharides such as, for example, starches, organic acids, such as alginic acid, salts of conjugated bases of organic acids, such as sodium alginate, agar and pectins; and their combinations.
    [00068] Non-tobacco fibers suitable for inclusion in homogenized tobacco material sheets are known in the art and include, but are not limited to: cellulose fibers; soft wood fibers; hardwood fibers; jute fibers, and combinations thereof. Prior to inclusion in the sheets of homogenized tobacco material, the non-tobacco fibers can be treated by the appropriate processes known in the art including, but not limited to: mechanical pulping; refining; formation of chemical pulp; bleaching; pulping with sulfate; and their combinations.
    [00069] The sheets of homogenized tobacco material for use in forming the rods as described in the present invention must have a tensile strength sufficiently high to survive the bundling to form the rods. In certain embodiments, non-tobacco fibers that can be included in the sheets of homogenized tobacco material in order to obtain an appropriate tensile strength. For example, sheets of homogenized tobacco material for rod formation as described in the present invention can comprise between about 1% and about 5% by weight of non-tobacco fibers on a dry weight basis.
    [00070] Aerosol builders and humectants suitable for inclusion in homogenized tobacco material sheets are known in the art and include, but are not limited to: polyhydric alcohols, such as triethylene glycol, 1 , 3-butane diol and glycerin; esters of polyhydric alcohols, such as glycerol mono-, di-triacetate; and aliphatic esters of mono-, di- or polycarboxylic acids, such as dimethyl dodecanedioate and dimethyl tetradecanedioate. Such aerosol builders and humectants can also be suitable as components of the second sheet comprising the non-tobacco flavor.
    [00071] For example, where rods according to the specification are suitable for use as aerosol-forming substrates in heated aerosol-generating articles, sheets of homogenized tobacco material for use in forming rods as described in the present The invention can have an aerosol builder content between about 5% and about 30% by weight on a dry weight basis. Rods that are suitable for use in the electrically operated and operated aerosol generating system that has a heating element may preferably include an aerosol former of more than 5% to about 30%. For rods that are suitable for use in the electrically operated aerosol generating system that has a heating element, the aerosol former may preferably be glycerin.
    [00072] It should be appreciated that the composition of the sheets of homogenized tobacco material can be designed to meet regulatory requirements.
    [00073] A number of reconstitution processes for producing sheets of homogenized tobacco materials are known in the art. These include, but are not limited to: papermaking processes of the type described, for example, in patent document US-A-3,860,012; casting or 'cast sheet' processes of the type described, for example, in patent document US-A-5,724,998; mass reconstitution processes of the type described, for example, in patent document US-A-3,894,544; and extrusion processes of the type described, for example, in patent document GB-A-983,928. Typically, the densities of sheets of homogenized tobacco material produced by extrusion processes and by mass reconstitution processes are greater than the densities of sheets of homogenized tobacco materials produced by casting processes.
    [00074] The sheets of homogenized tobacco material for use in forming rods as described in the present invention are preferably formed by a casting process of the type which generally comprises the casting of a paste comprising particulate tobacco and a or more binders on a conveyor belt or other support surface, drying the hollow paste to form a sheet of homogenized tobacco material and removing the sheet of homogenized tobacco material from the support surface.
    [00075] For example, in certain embodiments, sheets of homogenized tobacco material can be formed from the pulp comprising particulate tobacco, guar gum, cellulose fibers and glycerin by a casting process.
    [00076] The sheets of homogenized tobacco material can be textured by using appropriate machinery for the texturing of filter tow, paper and other materials.
    [00077] For example, sheets of homogenized tobacco material for forming rods as described in the present invention can be crimped using a crimping unit of the type described in patent document CH-A-691156, which comprises a pair of rotating crimping rolls. However, it should be appreciated that the sheets of homogenized tobacco material can be textured by using other appropriate machinery and processes that deform or perforate the sheets of homogenized tobacco material.
    [00078] Rods as described in the present invention can be produced from sheets of homogenized tobacco material and sheets of thermally conductive material that have different dimensions depending on their intended use. The sheets of homogeneous tobacco material and thermally conductive material must be of sufficient width to be grouped together to form a rod as described in the present invention.
    [00079] Preferably, sheets of tobacco material and sheets of thermally conductive material for use in rods as described in the present invention have a width of at least about 25 mm.
    [00080] In certain embodiments, sheets of material for use in rods as described in the present invention can have a width between about 25 mm and about 300 mm.
    [00081] Preferably, the sheets of material that make up the rod have a combined thickness of at least about 50 µm to about 300 µm.
    [00082] In certain embodiments, the individual sheets of material can have a thickness between 10 µm and about 250 µm. Thermally conductive sheets such as aluminum foil sheets may be less thick than sheets of aerosol-forming material.
    [00083] In certain embodiments, sheets of homogenized tobacco material can have a weight of 100 g / m2 and about 300 g / m2.
    [00084] Rods as described in the present invention may comprise a grouped sheet of homogenized tobacco material circumscribed by a porous wrap or a non-porous wrap.
    [00085] In certain embodiments, the rods as described in the present invention may comprise a sheet of homogenized tobacco material and a sheet of thermally conductive material grouped and circumscribed by a paper wrapper.
    [00086] Appropriate paper wrappers are known in the art and include, but are not limited to: cigarette papers; and filter plug wraps.
    [00087] In other embodiments, the rods as described in the present invention may comprise a non-paper wrap.
    [00088] Non-paper wrappers are known in the art and include, but are not limited to: homogenized tobacco materials.
    [00089] Rods as described in the present invention can be produced by using conventional cigarette making and cigarette filter making machinery, adapted to allow the grouping of two or more sheets simultaneously.
    [00090] For example, rods comprising a crimped sheet of homogeneous tobacco material and a sheet of thermally conductive material can be produced by using an adaptation of the machinery to form filter rods comprising a grouped crimped paper sheet of the type described in patent document CH-A-691156. The machinery could be adapted to allow a sheet of thermally conductive material to be bundled with the beaded tobacco sheet.
    [00091] As described in the present invention, there is also shown a method of forming a rod as described in the present invention, which comprises the steps of: providing a first web comprising a tobacco material, providing a second continuous leaf comprising a non-tobacco flavoring, simultaneous grouping of the first and second continuous leaves transversely in relation to its longitudinal axes; circumscription of the sheets grouped with a wrap to form a continuous rod, and division of the continuous rod into a plurality of distinct rods. The tobacco material is preferably homogenized tobacco. The leaf comprising a non-tobacco flavoring can be any leaf described above, and is preferably a sheet of paper or polymer comprising a non-smoking flavoring.
    [00092] The method can also comprise the texturing of the first web. For example, the method may comprise crimping, shaping, perforating or texturing the first web before grouping the first web with the second web.
    [00093] Preferably, the method also comprises crimping the first web.
    [00094] Both the first and second continuous sheets can be textured, for example, crimped.
    [00095] The specific modalities will also be described, by way of example only, with reference to the attached drawings, in which: Figure 1 shows a schematic cross section of the apparatus for forming a rod according to a specific modality; Figure 2 shows a schematic cross section of the apparatus for forming a rod according to a specific modality; Figure 3 illustrates an embodiment of an aerosol generating device that incorporates the rods formed as described in the present invention; and Figure 4 illustrates an aerosol generating system comprising an electrically operated aerosol generating device and an aerosol generating article as illustrated in Figure 3.
    [00096] The apparatus shown in Figure 1 generally comprises: a feeding means for supplying a continuous sheet of homogenized tobacco material; a feeding medium for providing a continuous sheet of polylactic acid (PLA) material, and the PLA coated with menthol flavoring; a crimping means for crimping the web of homogenized tobacco material; a rod forming means for bundling the continuous crimped sheet of tobacco material homogenized with the PLA continuous sheet and circumscribing the bundled material with a wrap to form a continuous rod; and a cutting means for dividing the continuous rod into a plurality of separate rods. The apparatus also comprises a transport means for transporting the web of homogenized tobacco material downstream through the apparatus, from the feed medium to the rod forming medium through the crimping means.
    [00097] As shown in Figure 1, the feed medium for supplying a continuous sheet of homogenized tobacco material comprises a continuous sheet of homogenized tobacco material 2 mounted on a first reel 4. The feeding medium for providing a continuous sheet of PLA comprises a continuous sheet of PLA 3 mounted on a second reel 5. The crimping means comprises a pair of rotating crimping rollers 6. In use, the continuous sheet of homogenized tobacco material 2 is extracted from the first reel 4 and transported downstream to the pair of crimping rollers 6 by the transport mechanism through a series of guide rollers and tensioners. While the continuous sheet of homogenized tobacco material 2 is fed between the pair of crimping rolls 6, the crimping rolls couple and crimp the continuous sheet of homogenized tobacco material 2 to form a continuous crimped sheet of homogenized tobacco material 8 that it has a plurality of ridges or corrugations separated from each other substantially parallel to the longitudinal axis of the sheet of tobacco material homogenized through the apparatus.
    [00098] The continuous crimped sheet of homogenized tobacco material 8 is transported downstream of the pair of crimping rolls 6 towards the rod forming medium. The PLA 3 web is transported from the second coil 5 to the rod forming medium. Both the sheet of PLA 3 and the sheet of homogenized beaded tobacco material 8 are fed simultaneously through a converging funnel or horn 10. The converging funnel 10 groups the continuous sheets of material 8, 3 transversely in relation to their longitudinal axes. . The continuous sheets of material 8, 3 assume a substantially cylindrical configuration as they pass through the converging funnel 10.
    [00099] With the removal of the convergent funnel 10, the grouped sheets of homogenized tobacco material and PLA coated with menthol are wrapped in a continuous sheet of enveloping material 12. The continuous sheet of enveloping material is fed from a coil 14 and enveloped in around the continuous crimped sheet grouped of tobacco material homogenized by an endless conveyor belt or a trim. As shown in Figure 1, the rod forming means comprises an adhesive application means 16 which applies adhesive to one of the longitudinal edges of the continuous sheet of wrapping material, so that when the opposite longitudinal edges of the continuous sheet of material surroundings are placed in contact, adhere to each other to form a continuous rod.
    [000100] The rod forming means also comprises a drying means 18 downstream of the adhesive application means 16 which, in use, dries the adhesive applied to the seam of the continuous rod as the continuous rod is transported downstream of the rod forming medium to the cutting medium.
    [000101] The cutting means comprises a rotary cutter 20 which divides the continuous rod into a plurality of separate rods of unit rod length or length of multiple unit rod.
    [000102] While the two continuous sheets of material are fed into the converging funnel while being coated, one leaf on top of the other, the rod has an even distribution of the tobacco leaf and PLA coated with menthol.
    [000103] In an alternative configuration illustrated in Figure 2, a continuous sheet of PLA coated with menthol 3 is positioned in an overlapping relationship with a continuous sheet of homogenized tobacco material 2 upstream of a pair of crimping rolls 6. The apparatus is then substantially as described above with respect to Figure 1.
    [000104] Both sheets of material 2, 3 pass through the crimping rollers 6 in the overlapping relationship and are crimped simultaneously. A crimped pair of webs 9 passes out of the crimping rolls 6 and downstream towards the converging funnel 10 to be formed like a rod.
    [000105] Figure 3 illustrates an embodiment of an aerosol generating article 1000 comprising a rod as described in the present invention. Article 1000 comprises four elements; an aerosol-forming substrate 1020, a hollow cellulose acetate tube 1030, a spacer element 1040, and a nozzle filter 1050. These four elements are arranged sequentially and in coaxial alignment and assembled by cigarette paper 1060 to form the article aerosol generator 1000. Article 1000 has an end of the mouth 1012, which a user inserts into his mouth during use, and a distal end 1013 located at the opposite end of the article to the end of the mouth 1012. The modality of a generating article aerosol dispenser illustrated in Figure 3 is particularly suitable for use with an electrically operated aerosol generating device comprising a heater for heating the aerosol-forming substrate.
    [000106] When assembled, article 1000 is about 45 mm long and has an outside diameter of about 7.2 mm and an inside diameter of about 6.9 mm.
    [000107] The aerosol forming substrate 1020 comprises a rod formed from a first sheet of curled hollow tobacco and a second sheet of PLA coated with menthol wrapped in filter paper (not shown) to form a plug.
    [000108] An aerosol generating article 1000 as illustrated in Figure 3 is designed to couple with an aerosol generating device in order to be consumed. Such an aerosol generating device includes a means for heating the aerosol forming substrate 1020 to a temperature sufficient to form an aerosol. Typically, the aerosol generating device may comprise a heating element surrounding the aerosol generating article 1000 adjacent to the aerosol forming substrate 1020, or a heating element which is inserted into the aerosol forming substrate 1020.
    [000109] Once coupled with an aerosol generating device, a user brings in the end of the mouth 1012 of the smoking article 1000 and the aerosol forming substrate 1020 is heated to a temperature of about 375 degrees Celsius. At this temperature, the volatile compounds are evolved from the hollow-leaf tobacco sheet of the aerosol-forming substrate 1020. These compounds condense to form an aerosol. The aerosol is pulled through the 1050 filter and into the user's mouth. PLA menthol is incorporated into the aerosol.
    [000110] Figure 4 illustrates a part of an electrically operated aerosol generating system 2000 that uses a heating blade 2100 to heat an aerosol generating substrate 1020 of an aerosol generating article 1000. The heating blade is mounted within a aerosol article receiving the chamber of an electrically operated aerosol generating device 2010. The aerosol generating device defines a plurality of holes for air 2050 to allow air to flow to the aerosol generating article 1000. Air flow is indicated by arrows in Figure 4. The aerosol generating device comprises a power supply and electronic components, which are not illustrated in Figure 4. The aerosol generating article 1000 of Figure 4 is as described with respect to Figure 3. Example 1
    [000111] Rods according to a first specific modality comprising a beaded sheet of homogenized tobacco material grouped with a non-beaded sheet of aluminum foil, circumscribed in a paper wrapper and with a rod length of 12 mm and diameters between 6.9 mm and 7.2 mm were produced at ratios between 20 m / min and 25 m / min when using a device of the type shown in Figure 1.
    [000112] The continuous sheets of homogenized tobacco material were produced by a casting process, in which the sheets have a width between 110 mm and 134 mm, a thickness of 120 µm to 260 µm, a weight between 167 g / m2e 201 g / m2 and a moisture content between 5% and 12%.
    [000113] The continuous sheets of paper are substantially the same width as homogenized tobacco and have a thickness of about 80 µm.
