    [001] The present invention relates to an aerosol-generating article comprising an aerosol-forming substrate and a biodegradable flavor-generating component to impart a taste to an aerosol inhaled by a consumer.
    [002] Articles in which an aerosol-forming substrate, such as a substrate containing tobacco, is heated and not burned are known in the art. Such articles can be called aerosol generators. The purpose of such heated aerosol-generating articles is to reduce the known harmful smoke constituents produced by combustion and the pyrolytic degradation of tobacco in conventional cigarettes. Typically, in such heated aerosol-generating articles, an inhalable aerosol is generated by transferring the heat from a heat source to a substrate or an aerosol-forming material, which can be located inside, around or downstream of the heat source . During consumption of the aerosol-generating article, volatile compounds are released from the aerosol-forming substrate by transferring heat from the heat source and entrained in the air extracted through the article. When the released compounds cool, they condense to form an aerosol that is inhaled by the consumer.
    [003] Conventional cigarettes heat the tobacco to a temperature that releases volatile compounds through the combustion of the tobacco itself. A consumer of a conventional cigarette inhales the smoke produced by the combustion of the tobacco, and all the aerosol associated with the smoke. To modify the flavor of the mainstream smoke or aerosol, it is known to provide cigarettes with single-segment and multiple-segment nozzle filters that include flavorings, such as menthol. Menthol can be incorporated into the filter, rolled tobacco rod, or liquid aerosol-generating substrate in liquid form by using an appropriate liquid carrier. The liquid forms of menthol are volatile and therefore tend to migrate or evaporate during storage and to flavor tobacco in cigarettes. Alternatively, menthol or another flavoring can be provided as a strip, a granule, or other means.
    [004] 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. In contrast, 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 the volatile compounds evolve. Since flavor additives such as menthol are highly volatile, they tend to evolve and be consumed earlier than other elements in the substrate. Unless the charge of menthol or flavor in the article is high, the taste decreases rapidly as the article is consumed.
    [005] When it is well known as menthol a conventional cigarette, the application of a menthol flavor, or another flavor, to an aerosol-generating article cannot 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 on the filter compared to a conventional cigarette.
    [006] The aerosol-forming substrate in an aerosol-generating article is typically a processed substrate that contains an aerosol-forming material such as glycerin. For example, the aerosol-forming substrate included in an aerosol-generating article and consumed in an aerosol-generating device may comprise a beaded or folded tobacco billet comprising a molded sheet or reconstituted tobacco. A flavor, such as menthol, can be loaded onto the aerosol-forming substrate. However, the structure of the aerosol-forming substrate can be compromised as a result. For example, the loading of menthol in a molded tobacco can reduce the density and strength of the molded leaf tobacco, which makes it less suitable for use as an aerosol-forming substrate in an aerosol-generating article.
    [007] It would be desirable to improve the addition of flavoring to aerosol-generating articles to improve the strength and consistency of the flavoring that can be added to such articles.
    [008] In one aspect, an aerosol generating article is provided which comprises a plurality of elements assembled in the form of a rod. The plurality of elements includes an aerosol-forming substrate, and a nozzle filter located downstream of the aerosol-forming substrate within the rod. The aerosol generating article comprises a volatile flavor generating component disposed between the aerosol forming substrate and the nozzle filter inside the rod.
    [009] As used herein, the aerosol generating article is any article that generates an inhalable aerosol when an aerosol-forming substrate is heated. The term includes articles comprising an aerosol-forming substrate that is heated by an external heat source, such as an electric heating element. An aerosol generating article can be a non-combustible aerosol generating article, which is an article that releases volatile compounds without combustion of the aerosol-forming substrate. An aerosol-generating article can be a heated aerosol-generating article, which is an aerosol-generating article that comprises an aerosol-forming substrate that must be heated and not burned in order to release the volatile compounds that can form an aerosol. The term includes articles comprising an aerosol-forming substrate and an integral heat source, for example, a combustible heat source.
    [0010] An aerosol-generating article can be a smoking article that generates an aerosol that is directly inhaled into a user's lungs through the user's mouth. An aerosol-generating article may resemble a conventional smoking article, such as a cigarette, and may comprise tobacco. An aerosol-generating article may be disposable. An aerosol generating article may alternatively be partially reusable and comprise a renewable or replaceable aerosol-forming substrate.
    [0011] As used herein, the term 'aerosol-forming substrate' refers to a substrate capable of releasing volatile compounds that can form an aerosol. Such volatile compounds can be released by heating the aerosol-forming substrate. An aerosol-forming substrate can be adsorbed, coated, impregnated or loaded onto a carrier or support. An aerosol-forming substrate may conveniently be part of an aerosol-generating article or smoking article.
    [0012] An aerosol-forming substrate can comprise nicotine. An aerosol-forming substrate may comprise tobacco, for example, it may comprise a tobacco-containing material that contains volatile tobacco flavor compounds, which are released from the aerosol-forming substrate upon heating. In preferred embodiments, an aerosol-forming substrate may comprise homogenized tobacco material, for example, molded leaf tobacco.
    [0013] As used herein, 'aerosol generating device' refers to a device that interacts with an aerosol-forming substrate to generate an aerosol. The aerosol-forming substrate is part of an aerosol-generating article, for example, part of a smoking article. An aerosol generating device may comprise one or more components used to supply energy from a power source to an aerosol-forming substrate to generate an aerosol.
    [0014] An aerosol generating device can be described as a heated aerosol generating device, which is an aerosol generating device comprising a heater. The heater is preferably used to heat an aerosol-forming substrate of an aerosol-generating article to generate an aerosol.
    [0015] An aerosol generating device may be an electrically heated aerosol generating device, which is an aerosol generating device comprising a heater that is operated by electrical energy to heat an aerosol forming substrate from an aerosol generating article to generate an aerosol. An aerosol generating device can be a gas-heated aerosol generating device. An aerosol generating device may be a smoking device that interacts with an aerosol-forming substrate of an aerosol-generating article to generate an aerosol that is directly inhaled into a user's lungs through the user's mouth.
    [0016] In preferred embodiments, the aerosol generating article can be substantially cylindrical in shape. The aerosol generating article can be substantially elongated. The aerosol generating article can have a length and a circumference substantially perpendicular to the length. The aerosol generating article can have a total length of between about 30 mm and about 100 mm. The aerosol generating article can have an external diameter between about 5 mm and about 12 mm.
    [0017] The aerosol-forming substrate can be substantially cylindrical in shape. The aerosol-forming substrate can be substantially elongated. The aerosol forming substrate can also have a length and circumference substantially perpendicular to the length. The aerosol forming substrate can be received in the aerosol generating device in such a way that the length of the aerosol forming substrate is substantially parallel to the direction of the air flow in the aerosol generating device.
    [0018] The aerosol forming substrate can be a solid aerosol forming substrate. Alternatively, the aerosol-forming substrate may comprise solid and liquid components. The aerosol-forming substrate may comprise a tobacco-containing material that contains volatile tobacco flavor compounds, which are released from the substrate upon heating. Alternatively, the aerosol-forming substrate may comprise a non-tobacco material. The aerosol forming substrate may also comprise an aerosol former. Examples of suitable aerosol builders are glycerin and propylene glycol.
    [0019] If the aerosol-forming substrate is a solid aerosol-forming substrate, the solid aerosol-forming substrate may comprise, for example, one or more of: powder, granules, pellets, scraps, spaghetti, strips or leaves containing one or more than: grass leaf, tobacco leaf, tobacco leaf fragments, constituted tobacco, homogenized tobacco, extruded tobacco and expanded tobacco. The solid aerosol-forming substrate may be in loose form, or it may be provided in an appropriate container or cartridge. For example, the aerosol forming material of the solid aerosol forming substrate can be contained within a paper or other wrapper and be shaped like a billet. Where an aerosol-forming substrate is in the form of a billet, the entire billet including the entire envelope is considered to be the aerosol-forming substrate.
    [0020] Optionally, the solid aerosol-forming substrate may contain additional volatile tobacco-flavored or non-tobacco compounds to be released by heating the solid aerosol-forming substrate. The solid aerosol-forming substrate may also contain capsules that, for example, include tobacco-flavored or non-volatile tobacco compounds, and such capsules may melt during heating of the solid aerosol-forming substrate.
    [0021] Optionally, the solid aerosol-forming substrate can be provided on or attached to a thermally stable carrier. The carrier can take the form of powder, granules, pellets, scraps, spaghetti, strips or leaves. The solid aerosol-forming substrate can be deposited on the carrier surface in the form of, for example, a sheet, foam, gel or paste. The solid aerosol-forming substrate can be deposited over the entire carrier surface or, alternatively, it can be deposited in a pattern in order to provide non-uniform flavor application during use.
    [0022] In one embodiment, the aerosol generating article has a total length of about 45 mm. The aerosol generating article may have an outside diameter of about 7 mm. In addition, the aerosol-forming substrate may have a length of about 10 mm. Alternatively, the aerosol-forming substrate may be about 12 mm long. In addition, the diameter of the aerosol-forming substrate may be between about 5 mm and about 12 mm.
    [0023] The nozzle filter is located at the downstream end of the smoking article. The filter may be a cellulose acetate filter billet. The filter can be about 7 mm in length in one embodiment, but it can be between 5 mm and about 10 mm in length. The aerosol generating article may comprise a spacer element located downstream of the aerosol-forming substrate.
    [0024] As used herein, a volatile flavor generating component is any volatile component that is added to an aerosol generating article in order to provide a flavor. The volatile flavoring component may be in the form of a liquid or a solid. The volatile flavor generating compound can be coupled with, or be associated with, a support element. The volatile flavoring component may be menthol or contain menthol.
    [0025] As used herein, the term 'menthol' denotes the compound 2-isopropyl-5-methyl cyclohexanol in some of its isomeric forms. Menthol can be used in solid or liquid form. In solid form, menthol can be provided as particles or granules. The term 'solid menthol particles' can be used to describe any granular or particulate solid material that comprises at least about 80% by weight of menthol.
    [0026] Preferably, 1.5 mg or more of the volatile flavor generating component is included in each aerosol generating article.
    [0027] As used herein, the term 'rod' is used to denote a generally cylindrical element of substantially circular, oval or elliptical cross-section.
    [0028] As used herein, the term 'longitudinal direction' refers to a direction that extends longitudinally, or parallel, to the cylindrical axis of a rod.
    [0029] The terms "upstream" and "downstream" can be used to describe relative positions of the elements or components of the aerosol generating article. For simplification purposes, the terms "upstream" and "downstream", as used herein, refer to a relative position along the rod of the aerosol-generating article with reference to the direction in which the aerosol is extracted through the rod.
    [0030] The distance between an aerosol forming substrate and a nozzle filter in a typical aerosol generating article is typically greater than the length of the nozzle filter. This intermediate section of an aerosol generating device typically comprises a high proportion of free space within which an aerosol can form, and in which a volatile flavoring agent can disperse. The amount of flavor-generating component that can be loaded in this section can advantageously be greater than that which can be loaded into the filter.
    [0031] By arranging the flavor-generating component between the aerosol-forming substrate and the nozzle filter, the flavor-generating component can infiltrate both of these components to the same extent, and the aerosol-forming substrate to a greater extent than would be the case if the flavor was located in the filter. The combination of a potentially greater charge of flavoring within the article and greater proximity to the aerosol-forming substrate may mean that the total amount of flavoring that infiltrates the aerosol-forming substrate is advantageously greater than would be the case if menthol was loaded in the filter. Advantageously, the taste can also infiltrate components of the article located between the aerosol-forming substrate and the nozzle filter.
    [0032] During consumption, the flavor-generating component infiltrated in the aerosol-forming substrate may last longer due to a greater load. In addition, the presence of a relatively high level of the flavor generating component inside the rod and infiltrating the nozzle filter can result in the survival of the flavor at desirable levels until the user has completely consumed the article.
    [0033] The volatile flavor generating component can be coupled to a fibrous support element. The fibrous support element can be any substrate or support suitable for locating, securing or retaining the flavor generating component. The fibrous support element can be, for example, a paper support. Such a paper support can be saturated with a liquid component such as liquid menthol. The fibrous support can be, for example, a thread or string. Such a thread or string can be saturated in a liquid component such as liquid menthol. Alternatively, such a thread or string can be threaded into or else coupled to a solid flavor generating component. For example, solid menthol particles can be coupled to a line.
    [0034] Preferably, the plurality of elements is assembled within a wrap to form the rod. Appropriate wraps are known to those skilled in the art. Preferably, the volatile flavor generating component is supported by an elongated fibrous support element, such as a thread or string. Preferably, the volatile flavor generating component is disposed radially into an inner surface of the wrap within the rod, and the fibrous support element has a longitudinal dimension arranged substantially parallel to a longitudinal axis of the rod. Where the intermediate section between the aerosol-forming substrate and the nozzle filter is enclosed within a wrap, this section is effectively a cavity within which the flavor-generating component can be retained. For the flavor-generating component to pass out of the article, it must pass through the aerosol-forming substrate or through the nozzle filter. When it passes through any of these elements, some flavor is retained. In this way, the effectiveness of a certain amount of volatile flavor generating component can be greater when the component is positioned between the aerosol-forming substrate and the nozzle filter within the article.
    [0035] It may be advantageous that the aerosol generating article comprises a low resistance support element located upstream of the nozzle and downstream of the aerosol forming element. The low strength support element comprises at least one channel longitudinally extended to locate the volatile flavor generating component within the rod. When consumed, a user draws in air from the article by pulling the nozzle filter. The aerosol generated inside the article passes through the nozzle and is inhaled by the user. It is desirable that the passage of air and aerosol between the aerosol-forming substrate and the nozzle filter is not faced with great resistance. In other words, it is desirable to have a minimum pressure drop between the aerosol-forming substrate and the nozzle filter. In this way, a support element for the flavor generating component can be termed as a low resistance support element if it provides a low resistance to the passage of air along a longitudinal direction of the rod, which can be termed as a low drag resistance. Drag resistance (RTD) is the pressure required to force air across the entire length of the object under test at a rate of 17.5 ml / s at 22 ° C and 101 kPa (760 torr). RTD is typically expressed in units of mm H2O and measured according to ISO 6565: 2011.
    [0036] It may be advantageous that the volatile flavor generating component is coupled to an elongated fibrous support and that the elongated fibrous support is located through a channel in a low resistance support element. It may be possible to form a low strength support element that contains the elongated fibrous support and then use the support element as a component element of the aerosol generating article.
    [0037] The low resistance support element can comprise a plurality of longitudinally extended channels. The low resistance support element can have a porosity between 50% and 90% in the longitudinal direction.
    [0038] The plurality of longitudinally extended channels in the low strength support element can be formed when processing a sheet material. Processing may include one or more processes selected from the list consisting of crimping, pleating, agglomeration or folding to form the channels.
    [0039] The plurality of longitudinally extended channels can be defined by a single sheet that is crimped, pleated, agglomerated or folded to form multiple channels. Alternatively, the plurality of longitudinally extended channels can be defined by the multiple sheets that have been crimped, pleated, agglomerated or folded to form multiple channels. The plurality of longitudinally extended channels can be defined by a single sheet that is pleated, collapsed or folded to form multiple channels. The sheet may also have been crimped.
    [0040] As used herein, the term 'sheet' denotes a laminar element that has a width and length substantially greater than its thickness.
    [0041] As used herein, the term 'longitudinal direction' refers to a direction that extends longitudinally, or parallel, to the cylindrical axis of a rod.
    [0042] As used herein, the term 'crimped' denotes a leaf that has a plurality of ridges or corrugations substantially parallel. Preferably, when the aerosol generating article is assembled, the substantially parallel ridges or corrugations extend in a longitudinal direction with respect to the rod.
    [0043] As used herein, the terms 'agglomerated', 'pleated' or 'folded' denote that a sheet of material is twisted, folded or compressed, or else constricted substantially transversely to the rod's cylindrical axis. A sheet can be crimped before it is agglomerated, pleated or folded. A sheet can be agglomerated, pleated or folded without first being crimped.
    [0044] The low resistance support element can have a total surface area between 300 mm2 per mm in length and 1,000 mm2 per mm in length. The low resistance support element can act as a heat exchanger to cool the aerosol generated within the article. The low resistance support element can alternatively be indicated as an aerosol cooling element.
    [0045] It is preferable that the air flow through the low resistance support element is not deflected to a substantial extent between adjacent channels. In other words, it is preferable that the air flow through the low resistance support element is in a longitudinal direction along a longitudinal channel, without a substantially radial deviation. In some embodiments, the bottom element of the resistance support is formed from a material that has a low porosity, or substantially no porosity with the exception of the longitudinally extended channels. That is, the material used to define or form the longitudinally extended channels, for example, a crimped and agglomerated sheet, has low porosity or substantially no porosity.
    [0046] In some embodiments, the low strength support element may comprise a sheet material selected from the group comprising a metallic sheet, a polymeric sheet and a substantially non-porous paper or cardboard. In some embodiments, the low strength support element may comprise a sheet 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 thin aluminum foil.
    [0047] After consumption, aerosol-generating articles are typically discarded. It may be advantageous that the elements that form the smoking article are biodegradable. Thus, it may be advantageous for the aerosol cooler to be formed from a biodegradable material, for example, a non-porous paper or a biodegradable polymer such as polylactic acid or a grade of Mater-Bi® (a commercially available family starch-based copolyesters). In some embodiments, the entire aerosol generating article is biodegradable or compostable.
    [0048] In some embodiments, the low resistance support element can be formed from a material that has a thickness between about 5 micrometers and about 500 micrometers, for example, between about 10 micrometers and about 250 micrometers - others. In some embodiments, the low strength support element has a total surface area between about 300 square mm per millimeter in length (mm2 / mm) and about 1,000 square mm per mm in length (mm2 / mm). In other words, for each millimeter of the length in the longitudinal direction the low resistance support element has between about 300 mm square and about 1000 square mm of surface area. Preferably, the total surface area is about 500 mm2 / mm per mm.
    [0049] The low strength support element can be formed from a material that has a specific surface area between about 10 mm square per milligram (mm2 / mg) and about 100 mm square per milligram (mm2 / mg ). In some embodiments, the specific surface area can be about 35 mm2 / mg.
    [0050] The specific surface area can be determined by taking a material that has a known width and thickness. For example, the material can be a PLA material that has an average thickness of 50 micrometers with a range of ± 2 micrometers. Where the material also has a known width, for example, between about 200 mm and about 250 mm, the specific surface area and density can be calculated.
    [0051] The low resistance support element can be directly coupled with or saturated with the flavor generating component.
    [0052] In some embodiments, phenolic compounds can be removed by interacting with the material that forms the low resistance support element. For example, phenolic compounds (for example, phenols and cresols) can be adsorbed by the material from which the low strength support element is formed.
    [0053] As noted above, the low resistance support element can be formed from a sheet of appropriate material that has been pleated, agglomerated or folded into an element that defines a plurality of longitudinally extended channels. A cross-sectional profile of such an element can show the channels as being randomly oriented. The low resistance support element can be formed by other means. For example, the low strength support element can be formed from a bundle of longitudinally extended tubes. The low strength support element can be formed by extruding, molding, laminating, or injecting an appropriate material.
    [0054] The low resistance support element may comprise a tube or an outer wrap that contains or locates the longitudinally extended channels. For example, a pleated, agglomerated or folded sheet material can be wrapped in a wrap material, for example, a billet wrap, to form the aerosol cooler. In some embodiments, the low strength support element comprises a sheet of crimped material that is agglomerated in a rod shape and connected by a wrap, for example, a filter paper wrap. The volatile flavor generating component is preferably incorporated within the low strength support element while it is being formed. For example, a line coupled to or saturated with a flavor-generating component can be deposited within a channel of the support element while the channel is formed.
    [0055] In some embodiments, the low resistance support element is formed in the form of a rod that has a length between about 7 mm (mm) and about 28 mm (mm). For example, a low strength support element can be about 18 mm long. In some embodiments, the low strength support element may have a substantially circular cross section and a diameter of about 5 mm to about 10 mm. For example, a low strength support element can have a diameter of about 7 mm.
    [0056] Preferably, the aerosol generating article comprises a spacer element located upstream of the volatile flavor generating component and downstream of the aerosol forming substrate. The spacer element can help locate the aerosol-forming substrate. The spacer element can be substantially tubular and can provide free space within which an aerosol can condense and within which a volatile flavor can permeate. The spacer element can be permeated with a flavor and contribute to the user's taste experience when consuming the article.
    [0057] In one aspect, a low resistance support element can be provided. The low strength support element comprises a volatile flavor generating component and can be used as a component element of an aerosol generating article. The low resistance support element can be any low resistance support element as described above with respect to the aerosol generating article.
    [0058] In one aspect, a method of fabricating a low strength support element is provided. The method comprises the steps of: forming a sheet material as an element that has a plurality of longitudinally extended channels, wherein the forming step comprises one or more processes selected from the list consisting of crimping, pleating, agglomeration and folding of the sheet material. The method then comprises the step of cutting the element to a desired length. A volatile flavor generating component is incorporated within the support element during formation. Preferably, an elongated fibrous support coupled to a volatile flavor generating component is deposited simultaneously within one of the longitudinally extended channels during the formation step of the sheet material. The method can be any method described above with respect to the aerosol generating article.
    [0059] A specific modality will now be described with reference to the Figures, in which:
    [0060] Figure 1 is a schematic cross-section diagram of a first embodiment of an aerosol generating article;
    [0061] Figure 2 is a schematic cross section diagram of a second embodiment of an aerosol generating article;
    [0062] Figures 3A, 3B and 3C illustrate the dimensions of a crimped sheet material and a rod that can be used to calculate the longitudinal porosity of the aerosol cooler.
    [0063] Figure 1 illustrates an embodiment of an aerosol generating article 10. Article 10 comprises four elements, an aerosol forming substrate 20, a hollow cellulose acetate tube 30, a low strength support element 40 that supports a menthol line 45, and a nozzle filter 50. These four elements are arranged sequentially and in coaxial alignment and are assembled by a cigarette paper 60 to form a rod 11. The rod 11 has a mouth end 12, which a user introduces in its mouth during use, and a distal end 13 located at the opposite end of the rod 11 to the end 12 of the mouth. The elements located between the mouth end 12 and the distal end 13 can be described as upstream of the mouth end 12 or, alternatively, downstream of the distal end 13. The embodiment illustrated in Figure 1 is particularly suitable for use with an aerosol generating device comprising a heater to heat the aerosol forming substrate.
    [0064] When mounted, the rod 11 is about 45 mm long and has an outside diameter of about 7.2 mm and an inside diameter of about 6.9 mm.
    [0065] The aerosol-forming substrate 20 is located upstream of the hollow tube 30 and extends to the distal end 13 of the rod 11. The aerosol-forming substrate 20 comprises a bead of molded leaf tobacco wrapped in paper filter (not shown) to form a billet. Molded leaf tobacco includes additives, including glycerin as an aerosol-forming additive.
    [0066] Tube 30 is located immediately downstream of the aerosol forming substrate 20 and is formed from cellulose acetate. A function of the tube 30 is to locate the aerosol forming substrate 20 for the distal end 13 of the rod 11 so that it can come into contact with a heating element. The hollow tube 30 acts to prevent the aerosol-forming substrate 20 from being forced along the rod 11 into the low strength support element 40 when a heating element is inserted into the aerosol-forming substrate 20. The hollow tube 30 it also acts as a spacer element to space the low strength support element 40 of the aerosol forming substrate 20.
    [0067] The low resistance support element 40 has a length of about 18 mm, an outer diameter of about 7.1 mm, and an inner diameter of about 6.9 mm. The aerosol cooler 40 is formed from a sheet of polylactic acid which is 50 mm ± 2 mm thick. The polylactic acid sheet has been crimped and agglomerated to define a plurality of channels that extend along the length of the low strength support element 40. To form the element, a sheet of polylactic acid is fed through crimping rolls to produce friezes or longitudinal corrugations. The crimped sheet is then agglomerated to form a cylinder that has a plurality of longitudinally extended channels. During the formation of the support element 40, a menthol line 45 is deposited on the crimped sheet parallel to the longitudinal strips. In this way, the menthol line 45 is incorporated within a longitudinal channel of the support element 40 as it is formed. The menthol line 45 will be loaded with a sufficient amount of menthol to provide an element 40 menthol charge of more than 1.5 mg.
    [0068] The total surface area of the low resistance support element 40 is between 8,000 mm2 and 9,000 mm2, which is equivalent to about 500 mm2 per mm in length. The specific surface area of the low strength support element 40 is about 2.5 mm2 / mg and has a porosity between 60% and 90% in the longitudinal direction.
    [0069] Porosity is defined here as a measure of unfilled space on a rod including an aerosol cooling element consistent with one discussed here. For example, if a rod 11 diameter were 50% not filled by element 40, the porosity would be 50%. Likewise, a rod would have 100% porosity if the internal diameter was completely unfilled and 0% porosity if completely filled. Porosity can be calculated using known methods.
    [0070] An exemplary illustration of how porosity is calculated is provided and illustrated here in Figures 3A, 3B and 3C. The low strength support element is formed from a sheet of material 1110 that has a thickness (t) and a width (w) and the area in cross section shown by an edge 1100 of sheet material 1110 is obtained by the width multiplied by the thickness. In a specific embodiment of a sheet material that has a thickness of 50 micrometers (± 2 micrometers) and a width of 230 mm, the cross-sectional area is about 1.15 x 10-5 m2 (this can be denoted as the first area). An exemplary beaded material is illustrated in Figure 3A with the labeled thickness and width. An example rod 1200 is also illustrated, with a diameter (d). The internal area 1210 of the rod is provided by the formula (d / 2) 2n. Assuming that an internal diameter of the rod that will eventually include the material is 6.9 mm, the area of unfilled space can be calculated as about 3.74 x 10-5 m2 (this can be denoted as the second area) .
    [0071] The higher the porosity in the longitudinal direction, the lower the resistance of the element.
    [0072] The nozzle filter 50 is a conventional nozzle filter formed from cellulose acetate, and has a length of about 45 mm.
    [0073] The four elements identified above are assembled by being tightly wrapped within a cigarette paper 60. Cigarette paper 60 in this specific embodiment is a conventional cigarette paper that has standard properties. The interference between the cigarette paper 60 and each of the elements locates the elements and defines the rod 11 of the aerosol generating article 10.
    [0074] Although the specific modality described above and illustrated in Figure 1 has four elements mounted on a cigarette paper, it is evident that an aerosol generating article may have additional elements or less elements.
    [0075] In storage after the apricot, a menthol vapor is evolved from the menthol line 45. This vapor is free to migrate within the aerosol-generating article 10. The menthol vapor infiltrates the aerosol-forming substrate 20. The menthol vapor it also infiltrates the hollow tube 30 and the nozzle filter 50.
    [0076] An aerosol generating article 10 as illustrated in Figure 1 is designed to couple with an aerosol generating device (not shown) in order to be consumed. Such an aerosol generating device includes a means for heating the aerosol forming substrate 20 to a temperature sufficient to form an aerosol. Typically, the aerosol generating device may comprise a heating element surrounding the aerosol generating article 10 adjacent to the aerosol forming substrate 20, or a heating element which is inserted into the aerosol forming substrate 20.
    [0077] Once coupled with an aerosol generating device, a user brings in the end 12 of the mouth of the article to smoke 10 and the aerosol forming substrate 20 is heated to a temperature of about 375 degrees Celsius. At this temperature, volatile compounds are evolved from the aerosol-forming substrate substrate 20. These compounds, which include the menthol flavoring, condense to form an aerosol. The aerosol is extracted through the rod 11 into the user's mouth.
    [0078] When the aerosol is extracted through the rod 11, the menthol flavoring infused in the hollow tube 30, the menthol line 45 and the nozzle filter 50 is also dragged in the aerosol to provide a taste experience for the consumer.
    [0079] Figure 2 illustrates a second embodiment of an aerosol generating article. When the item in Figure 1 is intended to be consumed in conjunction with an aerosol generating device, the item in Figure 2 comprises a combustible heat source 80 which can be ignited and transfers heat to the aerosol forming substrate 20 to form an inhalable aerosol. . The fuel heat source 80 is a charcoal element that is mounted in proximity to the aerosol-forming substrate at a distal end 13 of the rod 11. Article 10 of Figure 2 is configured to allow air to flow into the rod 11 and circulate through the aerosol-forming substrate 20 before being inhaled by a user. The elements that are essentially the same as the elements in Figure 1 have been given the same numbering.
    [0080] The exemplary modalities described above are not limiting. In view of the exemplifying modalities discussed above, other modalities consistent with the exemplifying modality above will now be apparent to an element versed in the technique.
