    Invention Patent Descriptive Report for AEROSOL GENERATOR SUBSTRATE FOR SMOKING ITEMS.
    The present invention relates to a fiber of homogenized tobacco material, an aerosol generating substrate comprising a plurality of homogeneous tobacco material fibers according to the invention, and a smoking article comprising an aerosol generating substrate of according to the invention.
    A number of smoking articles in which tobacco is heated rather than burned have been proposed in the art. The purpose of such heated smoking articles is to reduce the known harmful constituents of smoke produced by combustion and the pyrolytic degradation of tobacco in conventional cigarettes. Typically in heated smoking articles, an aerosol is generated by transferring heat from the 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. For example, in use, the combustible heat source of the heated smoking article is lit and the volatile compounds released from the aerosol generating substrate through the heat transfer from the combustible heat source are entrained in the air drawn through the heated smoking article. As the released compounds cool, they condense to form an aerosol that is inhaled by the consumer.
    For example, WO-A2-2009 / 022232 describes an article and smoke that comprises a combustible heat source, an aerosol generating substrate downstream of the combustible heat source and a heat conducting element around and in contact with a the rear portion of the combustible heat source and an adjacent front portion of the aerosol generating substrate, wherein the aerosol generating substrate extends at least about 3 mm downstream beyond the heat conducting element.
    Heated smoking articles that comprise a combustible heat source are high-energy devices that typically produce excess energy during use. To be used successfully in a
    2/26 such a heated smoking article, an aerosol generating substrate must be able to release sufficient volatile compounds for the production of a sensibly acceptable aerosol at temperatures produced within the aerosol generating substrate due to heat transfer to from the combustible heat source. However, combustion or pyrolytic degradation of the aerosol generating substrate at such temperatures, which can cause undesirable constituents to appear in the aerosol, must also be avoided.
    A number of aerosol-generating substrates containing tobacco or non-tobacco for use in heated smoking articles have been proposed in the art.
    For example, US-A-4,981,533 describes a source of flavor that can be thermally released for smoking articles that includes tobacco particles, an aerosol precursor that forms an aerosol on exposure to heat and a filler such as calcium carbonate or alumina that absorbs and radiates heat to minimize the likelihood that the flavor material may ignite. The thermally releasable flavor source described in US-A-4,981,533 has a low mass and a high surface area and is in the form of substantially uniform pellets that are packaged within a chamber in a smoking article. The pellets comprise a substantially straight cylinder with a length that is from 0.5 to about 1.5 times the diameter of the cylinder and has a length from about 0.5 to about 1.5 mm.
    There is still a need for an aerosol generating substrate containing tobacco to be used in heated smoking articles of the type described above that is capable of producing a sensorially acceptable aerosol, but which also has a high enough resistance to combustion to avoid substantially combustion or pyrolytic degradation thereof when using the heated smoking article.
    According to the invention, a fiber of homogenized tobacco material is provided which comprises an aerosol former, characterized in that the fiber has a weight ratio to the surface area
    3/26 of at least about 0.09 mg / mm 2 and aerosol-forming content of between about 12% and about 25% by weight on a dry weight basis (without water).
    In the form used here, in this patent application, the term fiber indicates a strip, filament, rod or other elongated element.
    In the form used here, in this patent application, the term length indicates the dimension in longitudinal direction of the fibers of the homogenized tobacco material according to the invention.
    In the form used here, in this patent application, the term transverse dimension indicates a dimension substantially perpendicular to the longitudinal direction of the homogenized tobacco material fibers according to the invention.
    In the form used here, in this patent application, the term homogenized tobacco material indicates a material formed by the agglomeration of tobacco fibers. To aid particle tobacco agglomeration, the homogenized tobacco material may comprise one or more intrinsic binders (i.e., endogenous tobacco binders), one or more extrinsic binders (i.e., extrinsic tobacco binders) or a combination thereof. Alternatively, or in addition, the homogenized tobacco material may comprise other additives including, but not limited to, aerosol builders, flavorings, plasticizers, humectants, tobacco and non-tobacco fibers, aqueous and non-aqueous solvents and combinations thereof. The fibers of homogeneous tobacco material according to the invention have an aerosol-forming content between about 12% and about 35% by weight on a dry weight basis (without water).
    According to the invention, the use of a homogenized tobacco material fiber according to the invention is also provided on an aerosol generating substrate of a smoking article.
    According to the invention, an aerosol generating substrate for a smoking article is also provided which comprises a plurality of fibers of homogenized tobacco material according to the invention.
    4/26
    In the form used here, in this patent application, the term aerosol generating substrate indicates a substrate capable of releasing volatile compounds when heated for the generation of the aerosol.
    It will be appreciated that the aerosol generating substrates according to the invention may have different shapes and sizes, depending on, for example, the type of smoking article in which they are intended to be used. The aerosol generating substrates according to the invention can be substantially three-dimensional. For example, the aerosol generating substrates according to the invention can be in the form of bricks, plugs or tubes comprising a plurality of fibers of homogeneous tobacco material according to the invention. Alternatively, the aerosol generating substrates according to the invention can be substantially two-dimensional. For example, the aerosol generating substrates according to the invention can be of woven material or sheets which comprise a plurality of fibers of homogenized tobacco material according to the invention.
    In the form used herein, in this patent application, the expression a plurality of fibers of homogenized tobacco material indicates any number of fibers of homogenized tobacco material capable of releasing sufficient volatile compounds when they are heated to generate a sensibly acceptable aerosol. For example, aerosol generating substrates according to the invention can comprise between about 20 fibers and about 180 fibers, of homogenized tobacco material according to the invention.
    According to the invention, a smoking article is also provided which comprises a heat source; and an aerosol generating substrate according to the invention.
    As described below, the weight ratio to the surface area and the aerosol formation content of the fibers of the homogenized tobacco material according to the invention in advantageous combination prevents the location of the heat transferred to the generation substrates aerosol according to the invention from the heat sources of the article
    5/26 smoking heated according to the invention while using it. This advantageously prevents the aerosol generating substrates according to the invention from reaching the temperatures required for the combustion or pyrolytic degradation of the fibers of the homogenized tobacco material according to the present invention.
    In use, the aerosol generating substrates in heated smoking articles can be heated through conduction heat transfer when the aerosol generating substrate is in direct contact with the heat source or a heat conducting element of the smoking article heated, through heat transfer by radiation; and by convection heat transfer, when the air heated by the heat source passes over the aerosol generating substrate.
    Without wishing to be bound by theory, heat transfer through convection is considered to have a high potential to overheat locally homogenized tobacco material during the drawing of hot air through; and thereby may result in the combustion or pyrolytic degradation of an aerosol generating substrate comprising homogenized tobacco materials during the use of a heated smoking article.
    The homogenized tobacco fibers according to the invention are advantageously capable of withstanding different modes of heat transfer, including heat transfer by convection due to the proportion of their higher weights with retention of the surface area and the content of the aerosol former.
    The weight to surface ratio is calculated by dividing the weight of the homogenized tobacco material fiber by the geometric surface area of the homogenized tobacco material fiber according to the following equation:
    Fiber weight of homogenized tobacco material (mg)
    Fiber surface area of homogenized tobacco material (mm 2 )
    The fibers of tobacco material homogenized according to
    The invention has a weight ratio to the surface area of at least about 0.09 mg / mm 2 . Preferably the fibers of homogenized tobacco material according to the invention have a weight to surface area ratio of at least about 0.1 mg / mm 2 . More preferably, the fibers of homogenized tobacco material according to the invention have a weight to surface area ratio of at least about 0.12 mg / mm 2 .
    Preferably, the fibers of homogenized tobacco material according to the invention have a weight to surface area ratio of less than or equal to about 0.25 mg / mm 2 .
    The high weight to surface area ratio of at least 0.9 mg / mm 2 of the fibers of homogenized tobacco material according to the present invention provides an increase in the available weight to be heated or unit of surface area, which results in an increased capacity to assimilate energy per unit surface area in use, this ensures a lower local increase in temperature in response to heat transfer, and thereby advantageously slows the fibers of homogenized tobacco material in accordance with the present invention of reaching a temperature required for combustion or pyrolytic degradation.
    In addition, the high weight to surface area ratio of at least 0.09 mg: mm 2 of the fibers of homogenized tobacco material according to the present invention restricts the availability of oxygen within the fibers required for combustion of the fibers. same. In use, this also advantageously slows the fibers of homogenized tobacco material according to the present invention to reach a temperature required for combustion or their pyrolytic degradation in response to heat transfer.
    The fibers of homogenized tobacco material according to the present invention which have a weight ratio for the surface area of at least about 0.09m mg: mm 2 therefore exhibit an increased resistance to combustion when compared to fibers of tobacco
    Homogenized 7/26 that have a weight ratio to the lowest surface area.
    To assess combustion resistance, visual confirmation of combustion can be obtained by observing the points of combustion (white ash against dark tobacco) on the surface of the homogenized tobacco material fibers after heating. This allows for a qualitative classification of the combustion resistance of fibers from homogenized tobacco material.
    In addition, a semi-qualitative determination of combustion can be obtained by measuring the isoprene content of the aerosol generated by the fibers of homogenized tobacco material. The isoprene content of the aerosol can be measured by suitable techniques known in the art such as, for example, gas chromatography.
    Isopropene is a product of the perolei of the isoprenoid compounds present in tobacco, for example, in certain tobacco waxes and can be present in the aerosol only if the fibers of homogenized tobacco material are heated to a temperature substantially higher than that required for the generation of an aerosol. In this way, the production of isoprene can be taken as representative of the amount of fibers of homogenized tobacco material that is overheated.
    Factors that affect the weight to surface area ratio of a fiber of homogenized tobacco material are the morphology (i.e., shape and dimensions) of the fiber and the density of the homogenized tobacco material.
    The density of the homogenized tobacco material determines the weight of a body of homogenized tobacco material of a given volume and the packaging efficiency of a given surface area of the homogenized tobacco material.
    The density of a homogenized tobacco material is usually largely determined by the type of process used to manufacture it. A number of reconstitution processes for the
    8/26 production of homogenized tobacco materials is known in the art. These processes include but are not limited to papermaking processes of the type described, for example, in US-A-5,724,998, foundry processes of the type described, for example, in US-A-5,724,998, mass reconstitution of the type described, for example, in US-A-3,894,544, and extrusion processes of the type described in, for example, CG-A-983,928.
    Typically, the densities of the homogenized tobacco materials produced through the extrusion and mass reconstitution processes are greater than the densities of the homogenized tobacco material produced through the casting processes. The densities of homogenized tobacco materials produced through extrusion processes can be greater than the densities of homogenized tobacco materials produced through mass reconstitution processes.
    Preferably, the fibers of homogenized tobacco material according to the invention have a density of at least about 1100 mg / cm 3 .
    Preferably, the fibers of homogenized tobacco material according to the invention have a density of about 1500 mg / cm 3 or less, more preferably of about 1450 mg / cm 3 or less, more preferably of about 1375 mg / cm 3 or less.
    Preferably, the fibers of homogenized tobacco material according to the invention have a density of between 1100 mg / cm 3 and about 1500 mg / cm 3 , more preferably between about 1100 mg / cm 3 and about 1450 mg / cm 3 , more preferably between about 125 mg / cm 3 and about 1375 mg / cm 3 .
    The density of the homogenized tobacco material according to the invention is determined by measuring the weight and dimensions of the fibers of homogenized tobacco material using precision weight instruments, calculating the fiber volume of the homogenized tobacco material at dimensions and dividing the weight of the homogenized tobacco material fiber by the volume of the fiber in the
    9/26 homogenized tobacco material.
    The weight ratio for the surface area of the homogenized tobacco materials can be adjusted by changing the shape and dimensions of the same materials

    Preferably, the fibers of homogenized tobacco material according to the invention have a maximum cross-sectional dimension of about 1.5 mm or less, more preferably of about 1.3 mm or less.
    The fiber length of the homogenized tobacco material according to the invention is advantageously at least three times the maximum transversal dimension of the same. This increases the cohesive capacity of the fibers and therefore facilitates the formation of two or three dimensional aerosol forming substrates according to the invention.
    Preferably the fiber length of the homogenized tobacco material according to the invention is at least five times its maximum cross-sectional dimension. More preferably, the fiber length of the homogenized tobacco material according to the invention is at least least ten times their maximum cross-sectional dimension.

    Preferably the aerosol former is one or more po12 / 26 lyric alcohols, more preferably, the aerosol former is glycerin.
    In use, the increased ability to assimilate energy per unit surface area of fibers of homogenized tobacco material according to the resulting invention by combining the ratio of high weight to surface area of them of at least 0.09 mg / mm 2 and the high aerosol builder content of between 12% and about 25% by weight, results in lower local increases in temperature within the aerosol generating substrates according to the invention in response transferring heat from a heat source.

    Examples according to the invention:
    Fibers of homogenized tobacco material according to the invention of substantially rectangular cut having the dimensions, densities, mass proportions for surface area and aerosol forming contents shown in Table 1 (samples 1 to 4) are produced by the processes of indicated in Table 1.
    Comparative examples not according to the invention:
    For purposes of comparison, fibers of homogenized tobacco material not according to the invention of substantially rectangular cut having the dimensions, surface areas, masses, mass proportions for surface area, densities and aerosol former contents shown in Table 1 (samples 5 to 7) are produced by the manufacturing processes indicated in Table 1.
    Combustion resistance in response to convection heat transfer of fibers of homogenized tobacco material according to the invention of samples 1 to 4 and fibers of homogenized tobacco material not according to the invention of samples 5 to 7 were evaluated.
    For each sample, five aerosol-generating substrates are produced comprising a plurality of fibers from the homogenized tobacco material that have a length of 7.1 mm, a diameter of 8 mm, a mass of 180 mg and a density of 0.5 g / cm 3 .
    To form the aerosol generating substrates, 180 mg of the fibers of homogenized tobacco material are placed inside a cylindrical quartz tube 10/26 bo having an internal diameter of 8 mm and held in place by a stainless steel wire mesh 12 gauge to form a 7.1 mm plug 14. The quartz tube is placed in a stainless steel outer jacket (not shown). As shown in figure 1, the cylindrical quartz tube 10 is coupled to a hot air generator comprising a nickel-chromium heating filament 16 twisted over a ceramic support 18 and held in a second quartz tube 20 with a screen perforated ceramic 22.
    The perforated ceramic screen 22 of the hot air generator minimizes the heating of the plug 14 by radiation. A distance of between about 0.5 mm and about 1 mm is maintained between the plug 14 and the perforated ceramic screen 22 of the hot air generator to also minimize heating of the plug 14 by conduction. The structure of the hot air generator and the location of the plug 14 thus favor the convection heating of the plug 14.
    The fibers of homogenized tobacco material are conditioned for 48 hours at 60% relative humidity at 22 ° C before being placed inside the quartz tube to assess its combustion resistance. To assess the combustion resistance of fibers of homogenized tobacco material in response to convection heat transfer, the nickel-chromium heating filament 16 of the hot air generator is heated by a regulated 63 W power supply and twelve puffs 55 ml (puff volume) are aspirated for 2 seconds each (puff duration) every 30 seconds (puff frequency) in the direction shown by the arrows in figure 1 using a programmable double syringe plunger.
    Visual confirmation of combustion can be obtained by observing combustion points (white ash against dark tobacco) on the surface of the upstream end (that is, the end closest to the nickel-chromium heating filament 16 of the hot air generator) ) of a plug 14 after convection heating. This allows a qualitative classification of the combustion resistance of the fibers of
    23/26 homogenized tobacco from each sample.
    In addition, a semi-quantitative determination of the combustion of the fibers of homogenized tobacco material is obtained by analyzing the isoprene content of the aerosol generated during the twelve puffs; as explained above, isoprene is a product of the perolei of isoprenoid compounds present in tobacco, for example, in some tobacco waxes. Isopropene can be present in the aerosol only if the fibers of homogenized tobacco material are heated to a temperature substantially higher than that required to generate the aerosol. In this way, the production of isoprene can be taken as representative of the amount of homogenized tobacco material that is overheated. The isoprene content of the aerosol generated during the twelve puffs is measured by gas chromatography.
    As shown in Table 1, the aerosols generated by the plugs comprising fibers of homogenized tobacco material according to the invention (samples 1 to 4) all contain 3 micrograms or less of isoprene per 12 puffs. In addition, the aerosols generated by the plugs comprising fibers of homogenized tobacco according to the invention of samples 1 to 3 do not contain detectable isoprene. This shows that tobacco in fibers of homogenized tobacco material according to the invention that have a mass to surface area ratio of at least about 0.09 mg / mm 2 and an aerosol-forming content of between about 12% and about 25% by weight is not significantly overheated as a result of convection heat transfer due to the suction of hot air through the plugs. In contrast, as shown in Table 1, the aerosols generated by the plugs comprising fibers of homogenized tobacco material not according to the invention (samples 5 to 7) all contain significant amounts of isoprene. This shows that tobacco in the fibers of homogenized tobacco material not according to the invention that have an aerosol former content of less than 12% by weight (sample 5) or a mass to surface area ratio of less than 0 , 09 mg / mm 2 (samples 6 and 7) is
    24/26 significantly overheated as a result of convection heat transfer due to the suction of hot air through the plugs.
    After convection heating, the five plugs formed by the fibers of homogenized tobacco material from each sample 5 were also visually inspected for signs of combustion. Photographs of the upstream end of three of the plugs formed by the fibers of homogenized tobacco material from samples 1 to 7 after heating by convection thereof are shown in figures 2 to 8, respectively. As shown in figures 2 to 8, due to the configuration of the equipment used to heat the plugs by convection heat transfer shown in figure 1, the fibers of homogenized tobacco material from each sample are not aligned substantially parallel to each other in the plugs . However, for the reasons previously indicated above, the plurality of fibers of homogenized tobacco material within the aerosol generating substrates according to the invention are preferably aligned substantially parallel to each other.
    As shown in figures 2 to 5, the plugs comprising the fibers of tobacco material homogenized according to the invention (samples 1 to 4) do not show any significant signs of combustion. In contrast, as shown in Figures 6 to 8, the plugs comprising fibers of homogenized tobacco material not according to the invention (samples 5 to 7) all show significant visual signs of combustion in the form of localized white combustion points .
    For comparison, an evaluation of combustion resistance in response to convection heating of the aerosol-generating substrate of a heated smoking article sold under the trade name Steam Hot One by Japan Tobacco Inc. was also done in the same way using the equipment shown in figure 1. The Steam Hot One heated smoking article comprises a combustible carbon-based heat source and an aerosol-generating substrate consisting of a plug comprising
    25/26 a plurality of tobacco material fibers downstream of the combustible heat source. The aerosol-generating substrate of the heated Steam Hot One smoking article is believed to comprise a mixture of approximately 60% by weight of tobacco cut filler fibers and approximately 40% by weight of reconstituted tobacco fibers. The tobacco material fibers of the steam hot one aerosol-generating substrate of the steam smoking hot one have an average mass to surface area ratio of about 0.06 mg / mm 2 and an average aerosol-forming (glycerin) content about 26% by weight.
    As the aerosols generated by the other plugs comprising fibers of homogenized tobacco material not according to the invention (samples 5 to 7), the aerosols generated by the plugs comprising fibers of tobacco material from the heated steam hot one smoking article contain significant amounts of isoprene (13.08 micrograms per plug). In addition, the plugs present significant visual signs of combustion in the form of localized white combustion points.
    Although the invention has been exemplified above with reference to fibers of homogenized tobacco material having a length of 10 mm, it will be recognized that fibers of homogenized tobacco material can be of different length.
    In addition, although the invention has been exemplified above with reference to homogenized tobacco material fibers of substantially rectangular cut, it will be recognized that the fibers of homogenized tobacco material can be of different shape. For example, fibers of homogenized tobacco material according to the invention may alternatively be substantially square or substantially circular cut fibers.
