[0009] An embodiment of the non-combustion heated tobacco according to the present invention will be described with reference to the drawings. The dimensions, materials, shapes, and relative arrangements of the components described in this embodiment are examples only. The processing sequence is also an example only, and can be changed as much as possible without departing from the problems and technical ideas of the present invention. It can be executed in parallel or in multiple ways. Therefore, unless otherwise specified, the technical scope of the invention is not limited to the following examples. In this specification, when the expression "~" is used, it shall be used to include the numerical values ​​or physical properties before and after it.

[0010] <Non-combustion heating type flavor inhalation product> Figure 1 is a schematic diagram showing an example of the configuration of a non-combustion heated flavor inhalation product according to this embodiment. The non-combustion heated flavor inhalation product 1 according to this embodiment comprises a non-combustion heated tobacco (non-combustion heated flavor inhalation article) 2 and an electric heating device 3 that heats the flavor generating segment 21 of the non-combustion heated tobacco 2 by electromagnetic induction heating.

[0011] The electric heating device 3 comprises a body 31, an inductor 32 for electromagnetic induction heating, a battery unit (power source) 33 that supplies operating power to the inductor 32, and a control unit 34 that controls the inductor. The body 31 has a cylindrical recess 35 and an air passage 36 that penetrates from the bottom surface, which is the innermost part (in other words, the deepest part) of the recess 35, to the outer surface of the end of the body 31 in the airflow direction. The inductor 32 is positioned on the inner side surface of the recess 35, at a position corresponding to the flavor-generating segment of the non-combustion heated tobacco 2 inserted into the recess 35. Specifically, the recess 35 is a heating chamber into which a non-combustion heated flavor inhalation article can be inserted through an opening. In Figure 1, the air passage 36 in the electric heating device 3 is a through-hole that penetrates in a straight line from the bottom surface of the recess 35 to the outer surface of the end of the body 31 in the airflow direction, but its shape is not particularly limited as long as it penetrates from the bottom surface of the recess 35 to the outer surface of the body 31. For example, the air passage 36 may be L-shaped and extend from the bottom of the recess 35 to the side end of the body 31. The electric heating device 3 may be activated by a manual operation such as an operating switch located on the body 31. Alternatively, the electric heating device 3 may operate automatically in response to the user inserting a non-combustion heated tobacco 2 into the recess 35 of the electric heating device 3. Furthermore, the end of the non-combustion heated tobacco opposite the mouthpiece may be engaged with the location of the recess 35 against which the end abuts, thereby generating airflow resistance.

[0012] The battery unit 33 supplies DC current. The control unit 33 includes a DC / AC inverter for supplying high-frequency AC current to the inductor 32. When the device is operating, the high-frequency alternating current passes through a dielectric coil that forms part of the inductor 32. This causes the inductor 32 to generate a fluctuating electromagnetic field. The frequency of the electromagnetic field is preferably between 1 MHz and 30 MHz, preferably between 2 MHz and 10 MHz, for example between 5 MHz and 7 MHz.

[0013] The non-combustion heated tobacco 2 is designed to work in conjunction with the use of an electrically operated electric heating device 3. The non-combustion heated tobacco 2 has a plate-shaped susceptor 212 inside a flavor-generating segment 21 containing a filler (flavor-generating segment filler) 211, which heats the filler 211 etc. by electromagnetic induction. The filler 211 is, for example, tobacco chips containing an aerosol base material. The plate-shaped susceptor 212 is formed of any material capable of converting electromagnetic energy into heat, such as metal.

[0014] When using the non-combustion heated flavor inhalation product 1, the user inserts the non-combustion heated tobacco 2 into the electric heating device 3 so that the portion having the plate-shaped susceptor 212 is in close proximity to the inductor 32. The inductor 32 is positioned around the recess 35 of the electric heating device 3. When the non-combustion heated tobacco 2 is inserted into the recess 35 of the electric heating device 3, the plate-shaped susceptor 212 of the non-combustion heated tobacco 2 is positioned within the fluctuating electromagnetic field generated by the inductor 32. The fluctuating electromagnetic field then generates eddy currents within the plate-shaped susceptor 212, resulting in the heating of the plate-shaped susceptor 212. Further heating is provided by the magnetic hysteresis loss within the plate-shaped susceptor 212.

[0015] The heated plate-shaped susceptor 212 then heats the filling 211 of the non-combustion heated tobacco 2 to a temperature sufficient to form an aerosol. The heating temperature at this time can be such that the filling 211 is heated to 250°C or higher and 400°C or lower. The heating temperature of the electric heated tobacco product is not particularly limited, but it is preferably 400°C or lower, more preferably 150°C or higher and 400°C or lower, and even more preferably 200°C or higher and 350°C or lower. The aerosol generated by heating passes through the mouthpiece segment 22 and is inhaled by the user.

[0016] The shape of the recess 35 of the electric heating device 3 is not particularly limited as long as it can accommodate the insertion of the non-combustion heated tobacco 2. For example, it may be cylindrical, or a polygonal prism such as a quadrangular or pentagonal prism. However, a cylindrical shape is preferable for the stability of holding the non-combustion heated tobacco 2. When the shape of the recess 35 is cylindrical, the diameter of the cylinder can be appropriately selected according to the size of the non-combustion heated tobacco 2. For example, it is preferably 5.5 mm or more and 8.0 mm or less, preferably 6.0 mm or more and 7.7 mm or less, and more preferably 6.5 mm or more and 7.2 mm or less. Furthermore, when both the shape of the recess 35 and the shape of the non-combustion heated tobacco 2 are cylindrical, the diameter of the recess is preferably between a value obtained by subtracting 0.5 mm from the diameter of the non-combustion heated tobacco 2 and the diameter of the non-combustion heated tobacco 2. By setting the diameter of the recess within this range, not only is the stability of holding the non-combustion heated tobacco 2 improved, but the gap between the recess 35 and the non-combustion heated tobacco 2 can be reduced, thereby obtaining the desired airflow resistance.

[0017] The side wall forming the recess 35 (inductor 32 in Figures 1 and 2) may be provided with a projection 37 for fixing the non-combustion heated tobacco 2, as shown in Figure 2. The height of the projection 37 from the side wall forming the recess 35 is not particularly limited, but from the viewpoint of stable holding of the non-combustion heated tobacco 2, it is preferably, for example, 0.3 mm or more and 2.0 mm or less, 0.5 mm or more and 1.5 mm or less, and more preferably 0.5 mm or more and 1.0 mm or less. Furthermore, if both the shape of the recess 35 and the shape of the non-combustion heated tobacco 2 are cylindrical, the diameter of the bottom surface of the recess is preferably, from the viewpoint of stable holding of the non-combustion heated tobacco 2, at least the diameter of the non-combustion heated tobacco 2 plus 0.5 mm, and at least the diameter of the non-combustion heated tobacco 2 plus 1.5 mm. By setting the diameter of the bottom surface of the recess to this range, not only is the stability of holding the non-combustion heated tobacco 2 improved, but a predetermined gap can be created between the recess 35 and the non-combustion heated tobacco 2, thereby preventing unintended deformation of the non-combustion heated tobacco 2. Furthermore, the cross-sectional area of ​​the non-combustion heated tobacco 2 can be changed by the projection 37, thereby obtaining the desired airflow resistance.

[0018] <Non-combustion heated tobacco (non-combustion heated flavor inhalation product)> Figure 3 shows an example of a non-combustion heated tobacco product (non-combustion heated flavor inhalation product). The non-combustion heated tobacco product 2 is a non-combustion heated tobacco product used with an electric heating device equipped with an inductor for electromagnetic induction heating, and comprises a flavor generating segment 21 and a mouthpiece segment 22. The mouthpiece segment 22 is a component for inhaling flavor components and includes a cooling segment 23 and a filter segment 24. The flavor generating segment 21, the cooling segment 23 and the filter segment 24 are connected in a predetermined direction and wound with a lining sheet 25. The direction in which the aerosol generated in the flavor generating segment 21 passes through the mouthpiece segment 22 and is inhaled by the user is called the ventilation direction. The non-combustion heated tobacco product 2 is rod-shaped, particularly columnar, and its longitudinal direction coincides with the ventilation direction.

[0019] The length of the ventilation direction for non-combustion heated tobacco is not particularly limited, but is usually 30 mm or more, preferably 40 mm or more, and more preferably 45 mm or more. Also, is usually 100 mm or less, preferably 85 mm or less, and 55 mm or less. It is preferable to have a certain state. The width of the base of the columnar body of the non-combustion heated tobacco is not particularly limited, but is usually 5.5 mm or more, preferably 6.8 mm or more, and usually 8.0 mm or less, preferably 7.2 mm or less.

[0020] The airflow resistance per non-combustion heated tobacco stick is, for example, 20 mmH2O or more and 110 mmH2O or less, preferably 20 mmH2O or more and 80 mmH2O or less, and more preferably 40 mmH2O or more and 70 mmH2O or less. Within this range, the user can be given a moderate smoking sensation. When a non-combustible heated tobacco is inserted into the recess (35) of the electric heating device, the non-combustible heated tobacco may be compressed due to the engagement relationship between the shape of the recess and the outer circumference of the non-combustible heated tobacco. Also, when the non-combustible heated tobacco is inserted to the abutment position of the recess, the tip surface of the non-combustible heated tobacco and the abutment portion of the recess engage. Therefore, when the non-combustible heated tobacco is used, i.e., when inserted into the recess of the electric heating device, the airflow resistance of the non-combustible heated tobacco may increase by 10 to 20 mmH2O compared to the airflow resistance when it is not inserted into the recess. By designing the airflow resistance of the non-combustible heated tobacco to be, for example, 20 mmH2O or more and 110 mmH2O or less, preferably 20 mmH2O or more and 80 mmH2O or less, and more preferably 40 mmH2O or more and 70 mmH2O or less when inserted into the recess, the user can be given a suitable smoking experience. The airflow resistance per non-combustion heated tobacco stick is measured according to the ISO standard method (ISO 6565:2015), for example, using an NCQA (manufactured by JT Toshi Co., Ltd.). It refers to the pressure difference between the mouthpiece end face (negative pressure) and the atmosphere when a predetermined airflow rate (17.5 cc / sec) of air is drawn in from the mouthpiece end face of the non-combustion heated tobacco stick. When air is drawn in from the mouthpiece end face, the atmosphere is introduced into the non-combustion heated tobacco stick from the tip and sides. Furthermore, the air permeability resistance of each segment is measured according to the ISO standard method (ISO 6565:2015), for example, using an air permeability resistance meter (product name: SODIMAX, manufactured by SODIM). The air permeability resistance of each segment refers to the pressure difference between the first and second end faces when a predetermined airflow rate (17.5 cc / sec) is passed from one end face (first end face, one of the bottom faces in the column shape) to the other end face (second end face, the bottom face opposite the first end face in the column shape) while air permeation is not permitted on the side faces of each segment (side faces in the column shape) in the direction of air permeability. The unit of air permeability resistance is generally expressed in mmH2O.

[0021] Furthermore, the compression change rate of each segment, measured by pressing the central part of the non-combustible heated tobacco and / or each segment in the airflow direction using the Borgwaldt method, is one indicator of hardness and is not particularly limited, but is, for example, 70% or more, preferably 80% or more, and more preferably 85% or more. The upper limit is, for example, 95% or less. By setting it within this range, for example, non-combustible heated flavor inhalant articles can be smoothly inserted into an electric heating type device, and when inserted, large deformation or damage to the non-combustible heated flavor inhalant articles during insertion and removal can be prevented. The Borgwaldt method is widely used to evaluate the hardness quality of tobacco filling rods and filters in tobacco products. For example, using a Borgwaldt DD60A measuring instrument, a load of 2 kg F is simultaneously applied from above to below 10 rods placed horizontally side by side. After applying the load F for 5 seconds, the average diameter of the rods is measured. The compression change rate (%) is expressed by the following formula. Compression change rate (%) = 100 × (Dd (diameter after strain)) / (Ds (diameter before strain)) In the above formula, Dd is the diameter of the rod section reduced by applying a load F, and Ds is the diameter of the rod section before applying a load F. In this method, 10 samples were measured 10 times (a total of 100 samples), and the average of these 10 measurement results was used as the measurement result using the conventional method. The two lower cylindrical rods and the two upper cylindrical rods are spaced at the same interval. When the length of the rod to be measured is shorter than the distance between these two rods, the measurement sample is 20 tubes are used for each measurement. Furthermore, the compression change rate mentioned above is one of the indicators that represent the hardness of non-combustion heated tobacco products, and is sometimes generally referred to as "hardness." Therefore, in this specification, the compression change rate will also be expressed as "hardness."

[0022] <Flavor-generating segment> The flavor-generating segment 21 is formed by winding a filler 211 and a plate-shaped susceptor 212 in a rolling paper 213. The filler 211 may contain at least one selected from, for example, tobacco leaves containing an aerosol base material, shredded tobacco, tobacco sheets, tobacco granules, ion exchange resin supported with nicotine, and tobacco extract, or it may consist of these components. The method of filling the rolling paper 213 with the filler 211 is not particularly limited, but for example, the filler 211 may be wrapped in the rolling paper 213, or the filler 211 may be filled into a rolling paper 213 formed in a cylindrical shape. If the shape of the tobacco filler 211 is a substantially rectangular parallelepiped with a longitudinal direction, the tobacco filler 211 may be filled so that its longitudinal direction is in an unspecified direction within the rolling paper 213, or it may be filled in an aligned manner so that it is in the axial direction of the tobacco-containing segment or perpendicular to the axial direction. Furthermore, for example, when using tobacco sheets, the tobacco sheets may be cut into strips with a width of 0.5 mm or more and 2.0 mm or less (length, for example, 5 mm or more and 40 mm or less) and filled into the gaps around the plate-shaped susceptor in a random orientation. Alternatively, the tobacco sheets may be cut into strips with a width of 1.0 mm or more and 3.0 mm or less (length, for example, 5 mm or more and 40 mm or less) and filled in an alignment parallel to the airflow direction. Alternatively, the tobacco sheets may be crimped (processed to create vertical grooves) and then gathered and filled. When the flavor generating segment 21 is heated, the tobacco components, aerosol base material, and water contained in the filling material 211 vaporize, and these are transferred to the mouthpiece segment 22 upon inhalation.

[0023] The embodiments of the filler 211 and the method of filling the flavor-generating segment 21 with the filler 211 will be described in more detail below. The conditions in each of the embodiments below can be combined to the extent possible. (a) After collecting parts such as leaves, veins, stems, roots, or flowers from tobacco plants of varieties selected from yellow varieties, Burley varieties, Oriental varieties, native varieties, other Nicotiana-tabacum varieties, and Nicotiana-rustica varieties, these collected parts are dried to a moisture content of approximately 10-15% by weight and prepared as a base material. Different varieties and parts of the tobacco plant may be blended according to the desired flavor. The base material is cut into pieces about 0.5-1.5 mm wide and filled into cylindrical rolling paper either randomly or roughly oriented in the vertical direction.

[0024] (b) After collecting leaves, veins, stems, roots, or flowers from tobacco plants of varieties selected from yellow varieties, Burley varieties, Oriental varieties, native varieties, other Nicotiana-tabacum varieties, and Nicotiana-rustica varieties, these collected materials are crushed and mixed with water and a binder to form a homogenized mixture which is then prepared as a base material in the form of a sheet, granules, or extruded rod. Different varieties and parts of the tobacco plant may be blended according to the desired flavor. When a granular base material (average particle size 0.2-2.0 mm) is used, it can be filled into cylindrical rolling paper. Furthermore, when a sheet-shaped base material (cut into pieces approximately 50-300 μm thick, 0.5-1.5 mm wide, and 5-40 mm long) is used as the base material, it can be filled into a cylindrical roll of paper in a random orientation, filled in a substantially longitudinal orientation, or filled into a cylindrical roll of paper in a gathered manner while remaining in sheet form (this may involve providing multiple channels through which air flows longitudinally).

[0025] (c) Leaves of selected plant varieties from herbs such as mint, basil, thyme, cilantro, rosemary, parsley, fennel, lemongrass, cinnamon, tea leaves, coffee beans, etc. A base material is prepared by drying parts such as leaf veins, stems, roots, fruits, or flowers, or tea leaves or coffee beans to a moisture content of approximately 10-15% by weight. Various herbs, tea leaves, and coffee beans may be blended according to the desired flavor. The base material is cut into small pieces about 0.5-1.5 mm wide and filled into cylindrical wrapping paper either randomly or roughly oriented in the vertical direction.

[0026] (d) Paper, which is a wet-laid non-woven fabric mainly composed of wood pulp (thickness 50-200 μm, basis weight 30-200 g / m²) 2 ), or dry laid non-woven fabrics mainly composed of natural or synthetic fibers. Nonwoven fabric sheets (thickness 200-2000 μm, basis weight 30-200 g / m²) 2 A porous material (a material having an open pore structure) made primarily from the fibers of non-tobacco plants such as ) is prepared as a base material. With such a base material, additives such as flavorings can be added to the pores, and because of the porous structure, the additives are stably retained at room temperature. The base material is cut into pieces with a width of about 0.5 to 1.5 mm and filled into a cylindrical roll paper in a random orientation, or filled in a substantially longitudinal orientation, or it can be gathered and filled into a cylindrical roll paper in a sheet shape (this may be a configuration in which multiple channels for air to circulate in the longitudinal direction are provided).

[0027] (e) Prepare a base material using a polymer as the main ingredient. The form of the polymer-based material is not particularly limited; for example, a mixture of thickening polysaccharides such as gellan gum, carrageenan, pectin, or agar with water and other additives, homogenized, and then with the water removed can be used. Depending on the type of thickening polysaccharide, the presence of cations such as calcium ions may strengthen the intermolecular crosslinking structure and form a stronger gel; therefore, calcium salts or potassium salts may be mixed in as needed. The method of removing the water is not particularly limited; for example, heating at room temperature, heating under reduced pressure, or freeze-drying can be used. Furthermore, the material may have an open-pore structure or a closed-pore structure. For example, to obtain a gel with an open-pore structure, a gelling agent, a gelling accelerator, and water can be homogenized to create a wet gel with a cross-linked structure between organic molecules. Then, by supercritical carbon dioxide treatment or freeze-drying, the water can be evaporated while retaining the cross-linked structure, thereby obtaining a gel with a low-density open-pore structure (also called an organic aerogel). In this case, flavor sources such as flavors, tobacco extracts, and crushed tobacco can be homogenized together with other raw materials, or the flavor source can be added externally to the pores in the pore structure after the production of the organic aerosol. Furthermore, to obtain a gel with a closed-pore structure, a gel can be obtained in which droplets or solid clumps of the flavor source are dispersed in the polysaccharide by homogenizing polysaccharides, water, and a flavor source such as flavor or tobacco extract, and then heating and drying at atmospheric pressure. This gel has a pore structure, but at room temperature, the pores are closed to the outside. In the embodiment where flavor sources are added to the pores, heating or the addition of moisture opens the pores, releasing the flavor sources within them. The base material can be processed into a granular shape (average particle diameter 0.2 to 2.0 mm) and filled into cylindrical wrapping paper. Alternatively, it can be processed into a sheet shape (thickness 50 to 300 μm), cut into grooves approximately 0.5 to 1.5 mm wide, and filled into cylindrical wrapping paper either randomly or with a roughly longitudinal orientation, or filled into cylindrical wrapping paper in a gathered manner (which may involve providing multiple channels through which air flows longitudinally) while remaining in sheet form.

[0028] The circumference of the flavor-generating segment 21 is not particularly limited, but is preferably 16 to 25 mm, more preferably 20 to 24 mm, and even more preferably 21 to 23 mm. The length of the flavor-generating segment 21 in the ventilation direction is not particularly limited, for example, it is usually 7 mm or more, preferably 10 mm or more, and more preferably 12 mm or more. Also, it is usually 60 mm or less, preferably 30 mm or less, and preferably 20 mm or less. It is preferable to have a certain state. The filling ratio of the filler 211 relative to the total volume of the flavor-generating segment 21 is typically 0.2 mg / mm³, based on the internal void volume of the flavor-generating segment 21. 3 More than 0.7mg / mm 3 The following applies:

[0029] The air permeability resistance of the flavor-generating segment 21 is, for example, 5 mmH2O or more and 60 mmH2O or less, preferably 10 mmH2O or more and 40 mmH2O or less, and more preferably 15 mmH2O or more and 35 mmH2O or less. Furthermore, the packing density of the filler 211 in the flavor-generating segment 21 is, the packing ratio (packing density) of the filler 211 relative to the total volume of the flavor-generating segment 21, is usually 0.2 mg / mm² based on the internal void volume of the flavor-generating segment 21. 3 More than 0.7mg / mm 3 The following may be used: 0.2 mg / mm³ 3 More than 0.6mg / mm 3 The following is acceptable. Within this range, for example, heat from the plate-shaped susceptor can be sufficiently transferred to the packing material 211, and unnecessary filtration of flavor components during suction can be suppressed, ensuring good release.

[0030] The filling material 211 holds a plate-shaped susceptor 212 inside the flavor-generating segment 21. The material of the plate-shaped susceptor 212 is, for example, metal, specifically, aluminum, iron, iron alloy, stainless steel, nickel, nickel alloy, or a combination of two or more of these. While materials other than metal, such as carbon, can also be used, metal is preferred from the viewpoint of easily forming the continuous ridge-like protrusions described later, and from the viewpoint of enabling good electromagnetic induction heating. The plate-shaped susceptor 212 is, for example, a plate-shaped member extending in the ventilation direction. The plate-shaped susceptor 212 is heated by eddy currents generated within the plate-shaped susceptor 212 by the fluctuating electromagnetic field generated by the inductor 32. The heated plate-shaped susceptor 212 heats the surrounding filling material 211, causing an aerosol to form. The plate-shaped susceptor 212 may have through holes that penetrate in the thickness direction. Furthermore, the plate-shaped susceptor 212 may have protrusions that extend in the thickness direction or the ventilation direction, or recesses that are recessed in the thickness direction or the ventilation direction. Also, two or more plate-shaped susceptors 212 may be arranged in parallel or in series with respect to the ventilation direction. In addition, the flavor-generating segment 21 may have susceptors of other shapes, such as thread-shaped or granular shapes, in addition to or instead of the plate-shaped susceptors 212. By increasing the surface area of ​​the plate-shaped susceptor 212 in contact with the filler 211, the aerosol generation efficiency can be improved.

[0031] The filler 211 may also contain an aerosol substrate that is liquid at 25°C, or an aerosol substrate that is gel-like at 25°C. Examples of aerosol substrates that are liquid at 25°C include one or more selected from the group consisting of glycerin, propylene glycol, triacetin, 1,3-butanediol, etc. The content of the liquid aerosol substrate relative to the weight of the filler 211 is usually 5% by weight or more and 50% by weight or less, preferably 10% by weight or more and 35% by weight or less, and more preferably 15% by weight or more and 30% by weight or less. If the filling material 211 contains a liquid aerosol base material, the liquid may migrate to the wrapping paper or mouthpiece components during manufacturing and transportation. By incorporating an aerosol base material that is gel-like at 25°C into the filling material 211, the aforementioned migration of the aerosol base material during manufacturing and transportation can be prevented. Aerosol substrates that are gel-like at 25°C can be prepared, for example, by mixing the required amounts of polysaccharides (gellan gum, agar, sodium alginate, carrageenan, starch, modified starch, cellulose, modified cellulose, pectin) or proteins (collagen, gelatin) with the aforementioned aerosol substrates that are liquid at 25°C (glycerin, propylene glycol, triacetin, 1,3-butanediol). For example, 0.2 to 1.0 by weight of native gellan gum can be added to glycerin containing 5 to 30% by weight of water. By incorporating it in a certain percentage, a gel-like aerosol base material can be formed at 25°C. When using other thickeners, the amount to be incorporated can also be determined according to the required gelling characteristics. The content of the gel-like aerosol base material relative to the weight of the filler 211 is usually 5% by weight or more and 50% by weight or less, preferably 10% by weight or more and 35% by weight or less, and more preferably 15% by weight or more and 30% by weight or less.

[0032] The components that may be included in the filling 211 will be described in detail below, but the manner in which they are included is not particularly limited. For example, they may be added during the manufacturing process of the filling 211, or added after manufacturing. Specifically, they may be added to the base material in the specific embodiments described in (a) to (e) above.

[0033] The filling material 211 may contain flavorings. The type of flavoring is not particularly limited, and from the viewpoint of imparting a good smoking taste, examples include fragrances and flavorings. Furthermore, other components such as coloring agents, humectants, and preservatives may be optionally included. The properties of the flavorings and other components are not limited; for example, they may be liquids or solids, and one type may be used alone, or two or more types may be used in any type and proportion.

[0034] Preferred flavorings may be used individually or in combination of two or more flavorings in any type and proportion, and may also include ingredients that provide a cooling or warming sensation. Examples of flavorings include sugars and sugar-based flavors, licorice, cocoa, chocolate, fruit juices and fruits, spices, liquor, herbs, vanilla, or floral flavors. In addition, flavorings can be those described in, for example, "Well-Known and Conventional Technical Information (Flavorings)" (March 14, 2007, published by the Japan Patent Office), "The Latest Dictionary of Flavorings (Popular Edition)" (February 25, 2012, edited by Soichi Arai et al., Asakura Shoten), or "Tobacco Flavoring for Smoking Products" (June 1972, RJ REYNOLDS TOBACCO COMPANY).

[0036] Examples of flavorings include components that exhibit sweetness, sourness, saltiness, umami, bitterness, astringency, or richness. Sweetening components include, for example, sugars, sugar alcohols, or sweeteners. Sugars include, for example, monosaccharides, disaccharides, oligosaccharides, or polysaccharides. Sweeteners include, for example, natural sweeteners or synthetic sweeteners. Components that produce a sour taste include, for example, organic acids (and their sodium salts). Examples of organic acids include acetic acid, adipic acid, citric acid, lactic acid, malic acid, succinic acid, or tartaric acid. Examples of bitter components include caffeine (extract), naringin, or wormwood extract. Examples of salty components include sodium chloride, potassium chloride, sodium citrate, potassium citrate, sodium acetate, or potassium acetate. Examples of components that contribute to umami include monosodium glutamate, monosodium inosinate, or monosodium guanylate. Components that contribute to astringency include, for example, tannins or shibuols.

[0037] Examples of colorants include natural pigments and synthetic pigments. Examples of natural pigments include caramel, turmeric, red yeast rice, gardenia, safflower, carotene, marigold, and annatto. Examples of synthetic pigments include tar dyes and titanium dioxide.

[0038] Examples of humectants include waxes, waxes, glycerin, medium-chain triglyceride fatty acids, or lipids such as fatty acids (short-chain, medium-chain, or long-chain fatty acids).

[0039] The total amount of flavorings in the filling 211 is not particularly limited, but from the viewpoint of providing a good smoking taste, for example, it is usually 10 ppm or more, preferably 10,000 ppm or more, more preferably 50,000 ppm or more, and also usually 250,000 ppm or less, preferably 200,000 ppm, more preferably 150,000 ppm or less, and even more preferably 100,000 ppm or less.

[0040] The filling material 211 may contain a flavor modifier, such as an acid or alkali. The types of acids that can be used as flavor modifiers are not particularly limited as long as they are edible, and examples include organic acids. In particular, acids that are liquid at room temperature (15-25°C) are preferred because they are easy to add when the flavor modifier is mixed with a solvent and sprayed. Specific examples of acids include stearic acid, isostearic acid, linoleic acid, oleic acid, palmitic acid, myristic acid, dodecanoic acid, capric acid, benzoic acid, isobutyric acid, propionic acid, adipic acid, acetic acid, vanillylmandelic acid, maleic acid, glutaric acid, fumaric acid, succinic acid, lactic acid, glycolic acid, or glutamic acid. These acids may be used individually or in combination of two or more types and proportions. Among these, preferred acids that are liquid at 15-25°C include, for example, isostearic acid, linoleic acid, oleic acid, isobutyric acid, propionic acid, acetic acid, or lactic acid. Lactic acid is particularly preferred because it is inexpensive, has little odor, and has little impact on flavor. The type of alkali that can be used as a flavoring agent is not particularly limited as long as it is edible. For example, alkali metal salts of carbonate, alkali metal salts of citric acid, sodium carbonate, sodium bicarbonate, potassium carbonate, or mixtures thereof may be used, or aqueous solutions obtained by dissolving these in suitable water may also be used.

[0041] The packing material 211 may contain granular susceptors, as described later. From the viewpoint of efficiently generating aerosols, the content of granular susceptors in the packing material 211 may be, for example, 1% by weight or more and 20% by weight or less, preferably 1% by weight or more and 15% by weight or less, and more preferably 1% by weight or more and 10% by weight or less.

[0042] When a base material as described in (a) to (e) above is used as the filler 211, there are no particular limitations on the method of incorporating aerosol base material, flavorings, flavor modifiers, granular susceptors, or other components into the base material, and can be carried out, for example, by the method shown below. Hereinafter, aerosol base material, flavorings, flavor modifiers, granular susceptors, or other components will be referred to as added components. (1) After manufacturing the base material, the additive components are added directly externally. (2) After manufacturing the base material, the liquid obtained by dissolving or dispersing the additive components in a solvent is added externally. (3) After manufacturing the base material, the additive components are dissolved or dispersed in a solvent, and then a thickening agent is added to adjust the viscosity (from a high-viscosity liquid state to a gel state) before being added externally. By adding the additive in this manner, it is possible to suppress seepage when a large amount of the additive is added. (4) After manufacturing the base material, the additive components are supported on a carrier and then added externally. (5) Additives are added directly during the manufacturing process of the base material. (6) In the process of manufacturing the base material, a liquid obtained by dissolving or dispersing additive components in a solvent is added externally. (7) In the process of manufacturing the base material, the additive components are supported on a carrier and added externally. As described in (5) to (7) above, the method of incorporating additives during the manufacturing process of the base material is particularly easy to implement in the specific embodiments (b), (d), and (e) of the filler 211 described above. Examples of the support materials mentioned above include dextrin, cyclodextrin, calcium carbonate, activated carbon, silica gel, and ion exchange resin. Furthermore, from the viewpoint of handling, the average particle size of the support material is preferably about 50 to 500 μm.

[0043] Furthermore, the thickness of the plate-shaped susceptor 212 is, for example, 30 μm or more and 1000 μm or less, preferably 50 μm or more and 500 μm or less, and more preferably 50 μm or more and 200 μm or less. Also, the length of the plate-shaped susceptor 212 in the ventilation direction is, for example, 6 mm or more and 60 mm or less, preferably a value of 4 mm or more less than or equal to the length of the flavor-generating segment 21 in the ventilation direction and less than or equal to the length of the flavor-generating segment 21 in the ventilation direction. The length of the plate-shaped susceptor 212 in the width direction perpendicular to the ventilation direction is, for example, 1 mm or more and 7 mm or less, preferably 2 mm or more and 6 mm or less, and more preferably 3 mm or more and 5 mm or less. By setting the range as described above, for example, the entire flavor-generating segment can be heated efficiently. The plate-shaped susceptor needs to have sufficient strength to prevent breakage when it is inserted into the flavor-generating segment at high speed. When the plate-shaped susceptor is subjected to a tensile test while both ends in the airflow direction are grasped, it is preferable that the breaking strength is 2N or more. The tensile test is performed, for example, by a company The test can be performed using a rheometer manufactured by Sun Science Co., Ltd., model number CR-3000EX-L, at a tensile speed of 50 mm / min. Depending on the material and shape of the plate-shaped susceptor, when the tensile test is performed, elongation occurs in the plate-shaped susceptor first, and the tensile stress measured by the rheometer's load cell increases. If the pulling continues, the plate-shaped susceptor will break. The above breaking strength refers to the maximum value of tensile stress recorded by the rheometer. After the tensile stress reaches its maximum value just before breaking, the tensile stress disappears.

[0044] The wrapping paper 213 can be made of paper, polymer film, or the like, and may consist of a single sheet or multiple sheets, and may also be coated on the outside or inside. For example, it may be selected from a laminated sheet in which paper and polymer film are laminated, or paper with a water-resistant coating on either the inside or outside, or both. The wrapping paper 213 may have low breathability. For example, the breathability may be less than 15 centrata. Preferably, the breathability is less than 10 centrata. With such a configuration, it is possible to prevent the formation of stains caused by the volatilization or leakage of volatile flavor sources and aerosol base materials from the flavor generation segment before and during use. If metal is placed in the winding paper 213 located between the inductor 32 and the plate-shaped susceptor, the fluctuating electromagnetic field generated by the inductor 32 during use will be absorbed, preventing the fluctuating electromagnetic field from being transmitted to the plate-shaped susceptor according to the design value. Therefore, it is preferable that the winding paper 213 located between the inductor 32 and the plate-shaped susceptor does not contain metal.

[0045] <Cooling Segment>

[0046] The mouthpiece segment may have a cooling segment, and the cooling segment 23 can be configured as a cylindrical member. The cooling segment is located downstream of the flavor segment. The vapor of the heated and vaporized aerosol base material or flavor source is introduced into the cooling segment, cooled, and liquefied (aerosolized). It is preferable that the cooling segment cools the temperature without removing a large amount of the vapor of the aerosol base material or flavor source generated in the flavor segment. For example, the difference between the internal temperature of the segment at the cooling segment inlet and the internal temperature of the segment at the cooling segment outlet may be 20°C or more during inhalation. As one aspect of the cooling segment, it may be a paper tube formed by processing a single sheet of paper or a plurality of laminated sheets into a cylindrical shape. Further, in order to increase the cooling effect by bringing the external air at room temperature into contact with the high-temperature steam, it is preferable that there are holes for introducing external air around the paper tube. By applying a polymer coating such as polyvinyl alcohol or a polysaccharide coating such as pectin to the inner surface of the paper tube, the cooling effect can be increased by utilizing the heat absorption of the coating and the heat of dissolution accompanying the phase change. The ventilation resistance of this cylindrical cooling segment is 0 mmH2O. As another aspect of the cooling segment, it is also preferable to fill the inside of the paper tube processed into a cylindrical shape with a cooling sheet member. In this case, by providing one or more air circulation channels in the flow direction, it is possible to achieve low-level component filtration while performing cooling by the cooling sheet member. It is desirable that the ventilation resistance of the cooling segment when filled with this cooling sheet is 0 - 30 mmH2O.

[0047] The total surface area of the cooling sheet member is 300 mm 2 / mm or more and 1000 mm 2 / mm or less. This surface area is the surface area per unit length (mm) in the ventilation direction of the cooling sheet member. The total surface area of the cooling sheet member is preferably 400 mm 2 / mm or more, more preferably 450 mm 2 / mm or more. On the other hand, it is preferably 600 mm 2 / mm or less, more preferably 550 mm 2 / mm or less.

[0048] It is desirable that the cooling segment 23 has a large surface area in its internal structure. Therefore, in a preferred embodiment, the cooling sheet member may be wrinkled to form channels in the flow direction and then formed by sewing, gathering, and folding a thin material sheet. Having many folds or pleats within a given volume of the element increases the total surface area of the cooling sheet member.

[0049] In some embodiments, the thickness of the constituent material of the cooling sheet member can be 5 μm or more and 500 μm or less, for example, 10 μm or more and 250 μm or less.

[0050] The cooling sheet material has a specific surface area of ​​10 mm². 2 / mg or more, 100mm 2 It can be formed from a material with a concentration of less than / mg. In one embodiment, the specific surface area of ​​the constituent material is approximately 35 mm². 2 It can be expressed as / mg.

[0051] The specific surface area can be determined by considering the material of the cooling sheet member having a known width and thickness. For example, the material of the cooling sheet member can be polylactic acid with an average thickness of 50 μm and a variation of ±2 μm. If the material of the cooling sheet member also has a known width, for example, between 200 mm and 250 mm, the specific surface area and density can be calculated.

[0052] Furthermore, using paper as the material for the cooling sheet component is desirable from the standpoint of reducing environmental impact. The paper used as the material for the cooling sheet should preferably have a basis weight of 30 to 100 g / m2 and a thickness of 20 to 100 μm. From the standpoint of minimizing the removal of flavor source components and aerosol base material components in the cooling segment, it is desirable for the paper used as the material for the cooling sheet to have low air permeability, preferably 10 Cholesta or less. By coating the paper used as the material for the cooling sheet with polymer porting such as polyvinyl alcohol, or with polysaccharides such as pectin, the cooling effect can also be increased by utilizing the endothermic effect of the coating and the heat of dissolution associated with the phase change.

[0053] The cylindrical member and the lining sheet 25 may be provided with openings (ventilation filters (Vf)) 231 that penetrate both. The presence of the openings 231 allows outside air to be introduced into the cooling segment 23 when suction occurs. As a result, the aerosol vaporized components generated by the heating of the flavor generating segment 21 come into contact with the outside air, their temperature decreases, causing them to liquefy and form aerosols. The diameter (extension length) of the openings 231 is not particularly limited, but may be, for example, 0.5 mm or more and 1.5 mm or less. The number of openings 231 is not particularly limited and may be one or two or more. For example, multiple openings 231 may be provided around the cooling segment 23.

[0054] The amount of outside air introduced through the opening 231 is preferably 85% by volume or less, and more preferably 80% by volume or less, of the total volume of gas drawn in by the user. By having a ratio of 85% by volume or less of outside air, the reduction in flavor due to dilution by outside air can be sufficiently suppressed. This can also be referred to as the ventilation ratio. From the viewpoint of cooling performance, the lower limit of the ventilation ratio is preferably 55% by volume or more, and more preferably 60% by volume or more. The ventilation ratio can be adjusted by appropriately adjusting the diameter and number of holes 231. The ventilation ratio is measured according to the ISO standard method (ISO 6565:2015), for example, using an NCQA (manufactured by JT Toshi Co., Ltd.). When a predetermined airflow rate (17.5 cc / sec) of air is drawn in from the mouthpiece end face of the non-combustible heated tobacco, air is introduced into the non-combustible heated tobacco from the tip of the non-combustible heated tobacco, the side of the flavor segment, and the opening 231. The ventilation ratio indicates the ratio of the airflow rate introduced from the opening 231 to the airflow rate drawn in from the mouthpiece end face (17.5 cc / sec).

[0055] The cooling segment 23 preferably exerts little resistance on the air passing through the tobacco rod. The airflow resistance of the cooling segment 23 is, for example, 0 mmH2O or more and 30 mmH2O or less, preferably 0 mmH2O or more and 25 mmH2O or less, and more preferably 0 mmH2O or more and 20 mmH2O or less. Preferably, the cooling segment 23 does not substantially affect the suction resistance of the aerosol-generating article. Furthermore, it is preferable that the pressure drop from the upstream end to the downstream end of the cooling segment 23 is small.

[0056] In some embodiments, the generated aerosol may experience a temperature drop of 10°C or more when it is drawn into the user through the cooling segment 23. In some embodiments, the generated aerosol may experience a temperature drop of 15°C or more in one embodiment, and 20°C or more in another embodiment, when it is drawn into the user through the cooling segment 23. The cooling segment 23 can be formed by other means. For example, the cooling segment 23 can be formed from a bundle of longitudinally extending tubes. The cooling segment 23 can be formed by extrusion, molding, lamination, injection, or shredding of a suitable material.

[0057] The cooling segment 23 can be formed, for example, by winding a pleated, gathered, or folded sheet material onto a cooling segment winding sheet. In some embodiments, the cooling segment 23 may include a sheet of wrinkled material formed by crimping paper or polymer film in the air permeability direction, gathering it into a rod shape, and then forming it onto a cooling segment winding sheet, such as filter paper cooling segment winding sheet. This configuration creates multiple air channels through which air flows in the air permeability direction of the cooling segment, resulting in low air permeability resistance, while the surrounding paper or polymer film absorbs heat as the air or vaporized components pass through the multiple channels, thus providing cooling.

[0058] The above-mentioned cooling sheet material, cooling segment winding paper (especially its inner surface), and cylindrical material may contain a flavor modifier. Examples of flavor modifiers include acids. The type of acid is not particularly limited, but edible acids can be used, such as organic acids. In particular, it is preferable that the acid is liquid at 15-25°C, i.e., room temperature. This is because, being liquid at room temperature allows the acid to be applied directly to the winding paper without being dissolved in a solvent such as water. Furthermore, by retaining the acid in a liquid state inside the winding paper, the acid is uniformly distributed within the paper, improving the contact efficiency between the acid and flavor components, thus allowing it to act efficiently on the flavor components. Examples of acids include stearic acid, isostearic acid, linoleic acid, oleic acid, palmitic acid, myristic acid, dodecanoic acid, capric acid, benzoic acid, isobutyric acid, propionic acid, adipic acid, acetic acid, vanillylmandelic acid, maleic acid, glutaric acid, fumaric acid, succinic acid, lactic acid, glycolic acid, and glutamic acid. Among these, examples of acids that are liquid at 15-25°C include isostearic acid, linoleic acid, oleic acid, isobutyric acid, propionic acid, acetic acid, and lactic acid. One of these acids may be used, or two or more may be used in combination. Among these, lactic acid is preferred because it is inexpensive, has little odor, and has little impact on flavor. Examples of flavor modifiers include alkalis. Specifically, alkali metal salts of carbonic acid, alkali metal salts of citric acid, sodium carbonate, sodium bicarbonate, potassium carbonate, and mixtures thereof may be used, or aqueous solutions obtained by dissolving these in appropriate water may be used.

[0059] The cooling segment 23 can be formed into a rod shape with a length in the ventilation direction of, for example, 10 mm or more and 40 mm or less, preferably 10 mm or more and 25 mm or less. For example, the length of the cooling segment in the ventilation direction can be 18 mm.

[0060] In some embodiments of the circumferential cross-section of the cooling segment 23, the cooling segment 23 is The cross-sectional shape in the ventilation direction is substantially circular, and the diameter can be 5.5 mm or more and 8.0 mm or less. For example, the diameter of the cooling segment 23 can be approximately 7 mm.

[0061] When the cooling segment has an opening for introducing external air, the ratio of the amount of air entering the cooling segment through the opening to the total amount of air entering the cooling segment, when air is drawn in from the suction end at 17.5 cc / sec, is usually 55% or more, preferably 60% or more, more preferably 65% ​​or more, and also usually 85% or less, preferably 80% or less, and more preferably 75% or less. Within this range, the cooling of the aerosol and the dilution of the flavor components are well balanced.

[0062] <Filter Segment> The mouthpiece segment may have a filter segment 24, and the filter segment 24 is not particularly limited as long as it contains a filter material and has the function of a general filter. For example, a tow made of synthetic fiber (also simply called "tow") or a cylindrical material such as paper can be used. General functions of a filter include, for example, adjusting the amount of air mixed when inhaling aerosols, reducing the taste, and reducing nicotine and tar, but the filter does not need to have all of these functions. In addition, in electrically heated tobacco products, which tend to produce fewer flavor components and have a lower filling rate of tobacco compared to conventional cigarette products, preventing the tobacco filling from falling out while suppressing the filtration function is also an important function.

[0063] The circumference of the filter segment 24 is not particularly limited, but is preferably 16 to 25 mm, more preferably 20 to 24 mm, and even more preferably 21 to 23 mm. The length of the filter segment 24 in the ventilation direction is preferably 4 mm or more, more preferably 7 mm or more, and also preferably 30 mm or less, and more preferably 20 mm or less, and is selected so that its ventilation resistance is preferably 10 mmH2O or more, more preferably 15 mmH2O or more, and also preferably 60 mmH2O or less, and more preferably 40 mmH2O or less. The length of the filter segment 24 in the ventilation direction is preferably 5 to 9 mm, and more preferably 6 to 8 mm. The cross-sectional shape of the filter segment 24 is not particularly limited, but can be circular, elliptical, polygonal, etc. The filter segment 24 may also have an additive release container or fragrance beads as described later, or fragrance may be directly added. Furthermore, the shape and dimensions of the filter media can be adjusted as appropriate so that the shape and dimensions of the filter segment 24 fall within the above range.

[0064] The configuration of the filter segments is not particularly limited and can be a plain filter containing a single filter segment or a multi-segment filter containing multiple filter segments, such as a dual filter or a triple filter. By using multiple segments, each segment can be assigned a different function. In addition, the outside of the packed layer may be wrapped with one or more sheets of filter segment winding paper.

[0065] The air permeability resistance per segment of the filter segment 24 can be appropriately changed depending on the amount and material of the filler packed into the filter segment 24. For example, if the filler is cellulose acetate fiber, the air permeability resistance can be increased by increasing the amount of cellulose acetate fiber packed into the filter segment 24. When the filler is cellulose acetate fiber, the packing density of the cellulose acetate fiber is 0.13 to 0.18 g / cm³. 3This is possible. The aforementioned airflow resistance is a value measured by, for example, an airflow resistance meter (product name: SODIMAX, manufactured by SODIM).

[0066] The filter segment 24 can be manufactured by known methods for manufacturing filter segments. For example, when synthetic fibers such as cellulose acetate tow are used as the material for the filter media, it can be manufactured by spinning a polymer solution containing a polymer and a solvent, and then crimping it. As an example of such a method, the method described in International Publication No. 2013 / 067511 can be used. In the manufacturing of the filter segment 24, the airflow resistance can be adjusted and additives (known adsorbents and fragrances (e.g., menthol), granular activated carbon, fragrance retainers, etc.) can be appropriately designed to be added to the filter media.

[0067] The form of the filter material included in the filter segment 24 is not particularly limited, and known forms may be adopted. For example, a cylindrical form of cellulose acetate tow can be used. The single filament fineness and total fineness of the cellulose acetate tow are not particularly limited, but in the case of a mouthpiece member with a circumference of 22 mm, the single filament fineness is preferably 5 g / 9000 m or more and 15 g / 9000 m or less, and the total fineness is preferably 8000 g / 9000 m or more and 25000 g / 9000 m or less. The cross-sectional shape of the cellulose acetate tow fibers can be circular, elliptical, Y-shaped, I-shaped, R-shaped, etc. In the case of a filter filled with cellulose acetate tow, a plasticizer such as triacetin may be added in an amount of 5% by weight or more and 10% by weight or less relative to the weight of the cellulose acetate tow in order to improve the filter hardness. Alternatively, a paper filter filled with sheet-shaped pulp paper may be used instead of the cellulose acetate filter. Furthermore, paper or non-woven fabric in a gathered shape may be used as the filter material. The filter material may also contain the flavor adjuster mentioned above.

[0068] The filter material may include a crushable additive release container (e.g., a capsule) containing a crushable outer shell made of gelatin or the like. The form of the capsule (also called an "additive release container" in the art) is not particularly limited, and known forms may be adopted. For example, it can be a crushable additive release container containing a crushable outer shell made of gelatin or the like, and its diameter may be 2 mm or more and 4 mm or less. In this case, when the capsule is destroyed by the user of the tobacco product before, during, or after use, it releases the liquid or substance (usually a flavoring agent) contained inside the capsule, which is then transferred to the tobacco smoke while the tobacco product is being used, and to the surrounding environment after use.

[0069] The filter segment 24 may be equipped with a winding paper (filter plug winding paper) for winding the filter material described above, from the viewpoint of improving strength and structural rigidity. The form of the winding paper is not particularly limited and may be bonded with an adhesive. The adhesive may include a hot melt adhesive, and the hot melt adhesive may further include polyvinyl alcohol. Furthermore, if the filter consists of two or more segments, it is preferable to wind each segment with a first winding paper, and then wind these multiple segments together with a second winding paper. The material of the roll paper is not particularly limited and any known material can be used, and it may also contain fillers such as calcium carbonate. The thickness of the rolled paper is not particularly limited, but is usually 20 μm or more and 140 μm or less, preferably 30 μm or more and 130 μm or less, and more preferably 40 μm or more and 100 μm or less. The basis weight of the rolled paper is not particularly limited, but is usually 20 gsm or more and 100 gsm or less, preferably 22 gsm or more and 95 gsm or less, and more preferably 23 gsm or more and 90 gsm or less. Furthermore, the roll paper may or may not be coated, but from the viewpoint of providing functions other than strength and structural rigidity, it is preferable to coat it with a desired material. In addition, the above-mentioned flavor adjuster may be contained in the surface of the roll paper, especially its inner surface (the side in contact with the filter material).

[0070] The filter segment 24 may further include a center hole segment having one or more hollow sections. The center hole segment is usually positioned on the flavor-generating segment side of the filter material, and preferably adjacent to the cooling segment.

[0071] <Modified example 1 of a plate-shaped susceptor> The plate-shaped susceptor 212 may be a metal plate with an uneven surface. Figure 4 is a perspective view showing an example of a plate-shaped susceptor 212. In the description of modified examples, the same reference numerals are used for corresponding components, and their descriptions are omitted. The plate-shaped susceptor 212 may have ridge-like protrusions 2121 on at least one of its front and back surfaces that are continuous along the ventilation direction, and the susceptor 212 in Figure 4 has three continuous ridge-like protrusions 2121.

[0072] Figure 5 is a schematic diagram illustrating the manufacturing method of a plate-shaped susceptor. As shown in the upper part of Figure 5, the manufacturing apparatus 4 is equipped with a plurality of rollers 41 and rolls the metal sheet 200, which is the material, while feeding it in a predetermined direction. The manufacturing apparatus 4 is also equipped with a cutter 42 for cutting the metal sheet 200 to create a plate-shaped susceptor 212. The middle part of Figure 5 shows a schematic plan view of the metal sheet at the corresponding position in the upper part. The lower part of Figure 5 shows a schematic cross-sectional view of the metal sheet at the corresponding position in the upper part. The metal sheet 200 is stretched in the feeding direction, for example, by being pulled back and forth between the rollers 41, and shrinks in the width direction of the metal sheet 200 perpendicular to the feeding direction. At this time, a wavy, uneven cross-section is formed on the metal sheet 200. The metal sheet 200 is further rolled by the rollers 41, and the unevenness is flattened to form ridge-like raised portions 2121. Such protrusions make it less likely for the position in which the filler 211 holds the plate-shaped susceptor 212 within the flavor-generating segment 21 to shift, and if the plate-shaped susceptor 212 has a coating layer described later, the coating layer is more easily held by the plate-shaped susceptor 212. Furthermore, the continuous ridge-like raised portions 2121 extending along the airflow direction of the plate-shaped susceptor 212 make it easier for the vapor generated by the vaporization of tobacco components and aerosol base materials contained in the filler 211 to flow smoothly along the airflow direction. In other words, the spaces between each ridge-like raised portion 2121 extending along the airflow direction can be suitably used as a flow path for the vapor of the tobacco components and aerosol base materials.

[0073] Furthermore, the raised portion 2121 may be interrupted in part in the ventilation direction, or it may be formed substantially parallel to the ventilation direction. Also, the number of raised portions 2121 may be one or more, and is not limited to three. In addition, the raised portion 2121 may have a meandering shape rather than a straight line when viewed from above.

[0074] <Modified example 2 of a plate-shaped susceptor> Figure 6 is a plan view illustrating a modified example of a plate-shaped susceptor. In the example shown in Figure 6, the plate-shaped susceptor 212 has multiple through-holes 2122 that penetrate through its front and back surfaces. The through-holes 2122 can be formed, for example, by creating slits in a metal plate 200 with a roller 41 equipped with blades, and then expanding the slits by rolling or pulling with the roller 41. Such through-holes also make it less likely for the position in which the filler 211 holds the plate-shaped susceptor 212 within the flavor-generating segment 21 to shift, and increase the surface area of ​​the plate-shaped susceptor 212 in contact with the filler 211, thereby improving the efficiency of aerosol generation.

[0075] <Modified example 3 of a plate-shaped susceptor> Figure 7 is a plan view illustrating a modified example of a plate-shaped susceptor. In this modified example, the plate-shaped susceptor 212 has ridge-like protrusions 2121 between the through holes 2122. That is, the plate-shaped susceptor 212 having through holes 2122 as shown in Figure 6 is modified to have the same configuration as shown in Figure 5. The raised portion 2121 is formed by the manufacturing method. In the example in Figure 7, the raised portion 2121 is formed continuously between the through holes 2122, but the raised portion 2121 may be interrupted in part in the longitudinal direction, or it may be formed substantially parallel to the longitudinal direction. Furthermore, the number of raised portions 2121 is not limited.

[0076] <Modified example 4 of a plate-shaped susceptor> Figure 8 is a diagram illustrating the end face of the plate-shaped susceptor 212. A projection in the thickness direction may be formed at the end of the plate-shaped susceptor 212 in the ventilation direction. In the example in Figure 8, the first curved surface portion 2123 on the surface of the end face of the plate-shaped susceptor 212, the second curved surface portion 2124 on the surface of the end face, the third curved surface portion 2125 near the back surface, and the projection 2126 protruding to the back surface side are shown. Such projections also make it less likely for the filler 211 to shift position in holding the plate-shaped susceptor 212 inside the flavor-generating segment 21. It is also preferable to form the projection at the end of the plate-shaped susceptor 212 in the width direction rather than in the thickness direction in order to prevent the filler 211 from shifting position in holding the plate-shaped susceptor 212.Therefore, the metal plate 200 may have projections at the end in the ventilation direction that protrude in a direction perpendicular to the ventilation direction, such as the thickness direction or the width direction.These projections are also effective in preventing the shifting of the coating layer, which will be described later.

[0077] <Modified example 5 of a plate-shaped susceptor> At least one of the front and back surfaces of the plate-shaped susceptor 212 may be textured, for example, by embossing or perforation. The three-dimensional shape and pattern of the surface due to the textured surface are not particularly limited, and various textures can be used for purposes such as improving the aerosol generation efficiency of the plate-shaped susceptor 212 or preventing displacement of the plate-shaped susceptor 212 within the flavor generation segment 21. By applying a textured surface, the contact area with the coating layer described later is increased, and heat transfer from the plate-shaped susceptor to the coating layer is increased.

[0078] <Modified versions of flavor-producing segments> Figure 9 illustrates a modified example of the flavor generating segment. The flavor generating segment 21 may comprise either a first coating layer 214 covering one side of the plate-shaped susceptor 212, or a second coating layer 215 covering the other side, or both. The first coating layer 214 and the second coating layer 215 are flavor sources, for example, containing an aerosol base material. The flavor source may include, for example, tobacco powder, an aerosol base material, a binder, and water. The filler 211 may also be, for example, wood pulp or other plant fibers that do not contain tobacco powder. By laminating such coating layers around the plate-shaped susceptor 212, the efficiency of aerosol and flavor component generation can be improved. Furthermore, if the plate-shaped susceptor 212 has the aforementioned ridge-like protrusions 2121, the coating layers are more easily retained on the plate-shaped susceptor 212. In this specification, unless otherwise specified, the term "coating layer" refers to either the "first coating layer" or the "second coating layer." The first and second coating layers can be formed by coating a plate-shaped susceptor with a mixture of a uniformly mixed material, such as crushed tobacco plant (one or more selected from the group consisting of leaf tissue, veins, stems, roots, flowers, etc.) (average particle size 30 μm or more and 300 μm or less), a binder (one or more selected from the group consisting of modified cellulose, modified starch, protein, thickening polysaccharides, etc.), an aerosol base material (one or more selected from the group consisting of glycerin, propylene glycol, triacetin, 1,3-butanediol, etc.), and water. Furthermore, flavorings, flavor adjusters, and plant fibers other than tobacco plants may be added. The flavor can be adjusted by blending multiple different varieties of tobacco plants as the tobacco plant to be included. The coating layers may also contain 1% to 4% by weight of nicotine. Furthermore, when tobacco plants are included in the first and second coating layers, the variety of flavors can be expanded by making the components contained in each coating layer different. For example, by changing the particle size of the crushed tobacco plants, one coating layer can contain components that deliver flavor components in the initial stages of heating, while the other coating layer contains components that deliver flavor components in the later stages of heating. It is possible to incorporate ingredients that can deliver flavor components into the product. More specifically, the specific embodiments (b), (c), or (e) of the filler 211 described above can be used as the material constituting the coating layer, and (b) is preferred from the viewpoint of flavor expression. In addition, additive components such as aerosol base materials, flavorings, flavor adjusters, granular susceptors, or other components that can be added to the filler 211 described above may be added to the coating material in a similar manner. Furthermore, the method for adding these additive components to the base material described above can also be applied to the method for adding additive components to the base material described for the filler 211.

[0079] The surface of either the first coating layer or the second coating layer, or both layers, can be subjected to a textured surface treatment. This treatment increases the surface area and improves the delivery of flavor components.

[0080] The thickness of the first coating layer 214 and the second coating layer 215 are, independently of each other, for example, 200 μm or more and 2000 μm or less, preferably 200 μm or more and 1000 μm or less, and more preferably 300 μm or more and 800 μm or less. By keeping the thickness within this range, aerosol generation and flavor source release are well maintained.

[0081] Figure 10 is a diagram illustrating a method for manufacturing a coated plate-shaped susceptor. In the example shown in Figure 10, the manufacturing apparatus 4 comprises a roller 41, a coating section 43, an oven 44, and a cutter 42. The metal plate 200, rolled by the roller 41, is then coated on both sides in the coating section 43 with a slurry containing tobacco powder and an aerosol substrate, and dried in the oven 44. The coated metal plate 200 is then cut by the cutter 42 to obtain a plate-shaped susceptor 212 with a first coating layer 214 and a second coating layer 215 laminated on top of each other.

[0082] <Example of coating layer variation 1> Figure 11 illustrates a modified coating layer. At least one layer selected from the first coating layer 214 and the second coating layer 215 each contains granular susceptors 216. The material of the granular susceptors 216 is, for example, a metal, specifically, aluminum, iron, iron alloy, stainless steel, nickel, nickel alloy, or a combination of two or more of these. While materials other than metals, such as carbon, can also be used, metal is preferred from the viewpoint of enabling good electromagnetic induction heating. The granular susceptors 216 are dispersed and mixed in, for example, the slurry described above, and then arranged in the first coating layer 214 and the second coating layer 215. It is preferable that the granular susceptors 216 are uniformly dispersed in the coating layers. The granular susceptors 216 are also heated by electromagnetic induction heating, and if the first coating layer 214 and the second coating layer 215 contain an aerosol substrate, they generate an aerosol. With this configuration, aerosols are generated more efficiently.

[0083] From the viewpoint of efficiently generating aerosols, the particle size of the granular susceptor is usually 30 μm or more and 300 μm or less, preferably 30 μm or more and 100 μm or less, and more preferably 50 μm or more and 100 μm or less. From the viewpoint of efficiently generating aerosols, the content of granular susceptors in each coating layer is usually 1% by weight or more and 20% by weight or less, preferably 1% by weight or more and 15% by weight or less, and more preferably 1% by weight or more and 10% by weight or less. Furthermore, the average distance from the surface of the granular susceptor 216 to the surface of the plate-shaped susceptor 212 is usually 100 μm or more and 1000 μm or less, may be 250 μm or more and 1000 μm or less, may be 100 μm or more and 500 μm or less, and preferably 150 μm or less. The average distance is 400 μm or less. By uniformly dispersing the granular susceptor in the coating layer, excessive contact between the plate-shaped susceptor 212 and the granular susceptor can be prevented. This average distance prevents excessive heating.

[0084] Furthermore, the granular susceptor 216 may be made of a different metal than the plate-shaped susceptor 212. For example, the material of the granular susceptor 216 may be selected such that its Curie temperature is lower than that of the plate-shaped susceptor 212. The control unit 34 may then detect the change in magnetism of the granular susceptor 216 due to its temperature reaching the Curie temperature, based on the magnitude of the current flowing through the inductor 32, and control the temperature of the plate-shaped susceptor 212 accordingly.

[0085] If the metal type of the granular susceptor 216 included in the coating layer is to be different from that of the plate-shaped susceptor 212, a coating layer without the granular susceptor 216 may be applied as a base coat to the plate-shaped susceptor 212 before applying the coating layer. This prevents galvanic corrosion caused by direct contact between different metal types. Alternatively, instead of applying the aforementioned coating layer without the granular susceptor as a base coat, an insulating polymer, starch, or cellulose may be coated onto the plate-shaped susceptor 212 as a base coat.

[0086] <Modification of the coating layer 2> Figure 12 is a diagram illustrating a modified coating layer. In the example shown in Figure 12, a chamfered portion 2141 is provided at the end of the first coating layer 214 in the ventilation direction. The chamfered portion 2141 may be a flat chamfer where the corners of a rectangular parallelepiped are cut into a flat surface, or a rounded chamfer where the corners are rounded. Alternatively, a chamfered portion may be provided at the end of the second coating layer 215 in the ventilation direction, either in place of the first coating layer 214 or in addition to the first coating layer 214. Providing such a chamfered portion ensures that when the plate-shaped susceptor 212 with the coating layer applied is introduced into the flavor segment at high speed during the high-speed manufacturing of the flavor generating segment 21, the corners of the coating layer are not damaged or detached. Since the coating layer contains tobacco, preventing the coating layer from detaching is preferable for consistently achieving consumer satisfaction.

[0087] <Modification of the coating layer 3> Figure 13 illustrates a modified example of the coating layer. In the example shown in Figure 13, a through-hole 2122 is provided in the plate-shaped susceptor 212, penetrating both sides. At least a portion of the interior of the through-hole 2122 is filled with the first coating layer 214, or the entire interior of the through-hole 2122 may be filled with the first coating layer 214. The material used for filling may be at least one of the materials constituting the first coating layer 214 and the materials constituting the second coating layer 215. Increasing the surface area of ​​the plate-shaped susceptor 212 in contact with the coating layer can improve the aerosol generation efficiency. Furthermore, the partial filling of the through-hole 2122 with the coating layer prevents shear displacement between the plate-shaped susceptor 212 and the coating layer.

[0088] <Modification of the coating layer 4> The first coating layer 214 and the second coating layer 215 may be made of the same material or of different materials.

[0089] <Modified example 6 of a plate-shaped susceptor> The plate-shaped susceptor 212 may have different surface roughness on its front and back sides. By appropriately setting the surface roughness, peeling of the first coating layer 214 and the second coating layer 215 from the susceptor 212 can be suppressed. Furthermore, even if no coating layer is provided, the positional displacement of the plate-shaped susceptor 212 within the flavor generating segment 21 can be suppressed by setting the surface roughness. This can suppress [the phenomenon]. By changing the surface roughness on the front and back sides, the contact surface area between the first coating layer 214 and the second coating layer 215 and the plate-shaped susceptor changes. As a result, a difference in heat conduction occurs, which can change the timing of the volatilization of flavor components and aerosol base materials inherent in the first coating layer 214 and the second coating layer 215.

[0090] <Examples of non-combustion heated tobacco products> Figure 14 is a diagram illustrating a modified example of a non-combustion heated tobacco product. Figure 14 shows a longitudinal cross-sectional view obtained by cutting the non-combustion heated tobacco product 2 along the thickness direction of the plate-shaped susceptor 212. The non-combustion heated tobacco product 2 comprises a tip segment 26, a flavor generating segment 21, a support segment 27, and a mouthpiece segment 22. The tip segment 26 is provided adjacent to the flavor generating segment 21 and on the side opposite the mouthpiece of the non-combustion heated tobacco product 2, and the support segment 27 is provided between the flavor generating segment 21 and the mouthpiece segment 22. Note that either the tip segment 26 or the support segment 27 may be omitted.

[0091] <Advanced Segment> The tip segment 26 is formed from a general filter material and, for example, has one or more through holes along the airflow direction. The material of the tip segment 26 may be mainly made from relatively heat-resistant plant pulp fibers, cellulose fibers, or regenerated cellulose fibers. The tip segment 26 may also be made of long cellulose acetate fibers solidified with a plasticizer (triacetin). By providing the tip segment 26, it is possible to suppress the spillage of the filling material 211 from the flavor generating segment 21 and the ejection of the plate-shaped susceptor 212. The tip segment 26 may also be formed from a porous, solid filter material. The length of the tip segment 26 in the airflow direction is, for example, 5 mm or more and 10 mm or less. The airflow resistance of the tip segment 26 is, for example, 0 mmH2O or more and 15 mmH2O or less. By lowering the airflow resistance of the tip segment, the impact on the overall airflow resistance of the non-combustible heated tobacco can be reduced.

[0092] The flavor-generating segment 21 may have a portion of the filler 211 interposed between the plate-shaped susceptor 212 and the tip segment 26. In other words, the plate-shaped susceptor 212 does not need to be in contact with the tip segment 26. This configuration makes it possible to suppress the plate-shaped susceptor 212 from directly heating the tip segment 26, thereby preventing deterioration, deformation, and other functional degradation of the tip segment 26 caused by direct heating.

[0093] Figure 15 shows an example of a longitudinal cross-sectional view obtained by cutting a non-combustion heated tobacco along the width direction of a plate-shaped susceptor. The plate-shaped susceptor 212 is provided with a chamfered portion 2126 such that the width of the end face opposite the tip segment 26 is reduced. This configuration also prevents the plate-shaped susceptor 212 from heating the tip segment 26. This prevents deterioration, deformation, and other functional degradation of the tip segment 26 caused by direct heating.

[0094] <Modified examples of the tip segment> The tip segment 26 may be configured such that the tip segment filler of the tip segment 26 is wound with tip segment wrapping paper. The tip segment filler of the tip segment 26 may include a gathered sheet made of paper or polymer. Alternatively, the tip segment filler of the tip segment 26 may include a gathered sheet made of nonwoven fabric. Here, a folded nonwoven fabric is referred to as a "gathered sheet". In these embodiments, through holes (channels) that penetrate in the direction of airflow are formed. Alternatively, a low-density nonwoven fabric may be compressed and folded before being filled into the tip segment; in this case, through holes (channels) that penetrate in the direction of airflow are not formed. The tip segment filler may contain a so-called flavor source. The flavor source may be, for example, a flavoring agent, tobacco extract, or tobacco powder. The tip segment wrapping paper of the tip segment 26 may be a paper-aluminum laminated sheet. Such a tip segment wrapping paper can be heated by an induced current or by heat transfer from the plate-shaped susceptor 212 of the flavor generating segment 21, and the heat of the tip segment wrapping paper can cause the flavor components to volatilize if the tip segment 26 contains a flavor source.

[0095] <Support Segment> The support segment 27 is also formed from a general filter material and, for example, has one or more through holes along the airflow direction. The support segment 27 may also be made of cellulose acetate long fibers solidified with a plasticizer (triacetin). By providing the support segment 27, it is possible to suppress the plate-shaped susceptor 212 from popping out of the flavor generating segment 21. The support segment 27 may also be formed from a porous, solid filter material. The support segment filler of the support segment 27 may include a gathered sheet made of paper or polymer. The support segment filler of the support segment 27 may also include a gathered sheet made of nonwoven fabric. In these embodiments, through holes (channels) penetrating in the airflow direction are formed. The support segment filler of the support segment 27 may also include a so-called flavor source. The flavor source may be, for example, a fragrance, tobacco extract, or tobacco powder. The support segment wrapping paper of the support segment 27 may be a paper-aluminum laminated sheet. The length of the support segment 27 in the airflow direction is, for example, 5 to 10 mm. Furthermore, the airflow resistance of the support segment 27 is 0-15 mmH2O. By lowering the airflow resistance of the support segment, the impact on the overall airflow resistance of the non-combustible heated tobacco can be reduced. Moreover, lowering the airflow resistance of the support segment prevents a significant reduction in the vapor of flavor components and aerosol base material generated in the flavor segment due to filtration and adsorption.

[0096] <Modification 1 of the lining sheet> Figures 16(a) to (d) illustrate variations of the lining sheet. The lining sheet is not particularly limited as long as it wraps at least a part of the flavor-generating segment 21 and a part of the mouthpiece segment 22, and other segments can also be wrapped together. For example, in the case of a configuration having a tip segment 26 and a support segment 27, as shown in Figures 16(a) to (d), the tip segment 26, flavor-generating segment 21, support segment 27, and mouthpiece segment 22 may be wrapped by a single lining sheet 25. By using a lining sheet 25 that is comfortable to hold and has good printability, a non-combustion heated tobacco product 2 with good usability and appearance quality can be realized. The lining sheet 25 is not particularly limited as long as it is wrapped around at least a portion of the flavor-generating segment 21 and a portion of the mouthpiece segment 22, but from the viewpoint of ensuring sufficient comfort in the mouth and printability, it is preferable to wrap it around at least a portion of the flavor-generating segment 21 and all of the mouthpiece segment 22. The form of the lining sheet 25 is not particularly limited, and for example, one in which pulp is the main component can be cited. As for the pulp, in addition to being made from wood pulp such as softwood pulp or hardwood pulp, it may also be obtained by mixing and manufacturing non-wood pulp commonly used for rolling paper for tobacco products, such as flax pulp, hemp pulp, sisal pulp, and esparto. These pulps may be used individually or in combination of multiple types in any proportion. Furthermore, the lining sheet 25 may consist of a single sheet, or it may consist of multiple sheets or more. As for the form of pulp, chemical pulp produced by methods such as Kraft pulping, acidic, neutral, or alkaline sulfite pulping, or soda salt pulping, as well as gland pulp, chemigland pulp, and thermomechanical pulp can be used. The lining sheet 25 may be manufactured using the manufacturing method described later, or a commercially available product may be used. The shape of the lining sheet 25 is not particularly limited and can be, for example, a square or a rectangle.

[0097] The thickness of the lining sheet 25 is not particularly limited, but from the viewpoint of grip comfort and printability, it is usually 30 μm or more and 60 μm or less, and preferably 40 μm or more and 50 μm or less. The basis weight of the lining sheet 25 is not particularly limited, but from the viewpoint of gripping comfort and printability, it is usually 30 gsm or more and 60 gsm or less, preferably 35 gsm or more and 50 gsm or less, and more preferably 35 gsm or more and 40 gsm or less. The breathability of the lining sheet 25 is not particularly limited, but from the viewpoint of grip comfort and printability, it is usually 0 Cholesta units or more and 30 Cholesta units or less, and preferably greater than 0 Cholesta units and 15 Cholesta units or less. The breathability is a value measured in accordance with ISO 2965:2009, and is measured per 1 cm² area per minute when the differential pressure on both sides of the paper is 1 kPa. 2 Flow rate of gas passing through (cm 3 It is expressed as follows: 1 cholesta unit (1 cholesta unit, 1 C.U.) is equivalent to 1 cm at 1 kPa. 3 / (min·cm 2 ) The smoothness of the lining sheet 25 is not particularly limited, but from the viewpoint of gripping comfort and printability, it is usually 200 seconds or more and 1500 seconds or less, preferably 250 seconds or more and 1000 seconds or less, and more preferably 300 seconds or more and 500 seconds or less.

[0098] The opacity of the lining sheet 25 is not particularly limited, but from the viewpoint of ensuring the desired appearance quality, it is usually 70% or more and 100% or less, preferably 75% or more and 95% or less, and more preferably 80% or more and 90% or less. Opacity is measured using a photovoltaic reflectometer in accordance with JIS-P8138. Smoothness is measured in accordance with JIS-P8117 and JIS-P8119. The basis weight of the sheet is measured in accordance with JIS-P8124.

[0099] From the viewpoint of being able to block leakage and staining of the liquid contained in the filling 211 of the flavor generating segment 21, the lining sheet 25 is preferably a liquid-impermeable sheet. Examples include a sheet made by laminating a polymer film mainly composed of polyolefin or polyester with paper, or a sheet made by coating paper with a coating agent such as modified cellulose, modified starch, or polyvinyl alcohol.

[0100] The lining sheet 25 may contain fillers in addition to the pulp described above. Examples include metal carbonates such as calcium carbonate and magnesium carbonate, metal oxides such as titanium oxide, titanium dioxide, and aluminum oxide, metal sulfates such as barium sulfate and calcium sulfate, metal sulfides such as zinc sulfide, quartz, kaolin, talc, diatomaceous earth, and gypsum. In particular, it is preferable to include calcium carbonate from the viewpoint of improving whiteness and opacity and increasing the heating rate. These fillers may be used individually or in combination of two or more.

[0101] In addition to the pulp and fillers mentioned above, the lining sheet 25 may contain various additives. For example, it may contain a water-resistant enhancer to improve paper strength when it contains moisture. Water-resistant enhancers include wet-strength enhancers (WS agents) and sizing agents. Examples of wet-strength enhancers include urea-formaldehyde resin, melamine-formaldehyde resin, and polyamide epichlorohydrin (PAE). Examples of sizing agents include rosin soap, alkyl ketene dimer (AKD), alkenyl succinic anhydride (ASA), and highly saponified polyvinyl alcohol with a saponification degree of 90% or higher.

[0102] A coating agent may be added to at least one of the two surfaces of the lining sheet 25, which is its front and back surfaces. There are no particular restrictions on the coating agent, but a coating agent that can form a film on the surface of the paper and reduce the permeability of liquids is preferred. As an example of a coating agent, the lining sheet 25 may have a lip-release agent applied to its outside, which improves the feel in the mouth. For example, nitrocellulose or ethylcellulose can be used as the lip-release agent. If the lip-release agent is applied to the inside of the lining sheet 25, it is possible to prevent liquid components such as aerosol base materials contained in the flavor segment from seeping into the inside of the lining sheet 25.

[0103] The multiple segments can be fixed by the lining sheet 25 by applying an adhesive such as vinyl acetate emulsion or starch paste to one side (the inner surface when rolled) of the lining sheet 25, either entirely or partially, before or after application, and then arranging the multiple segments on one side (the inner surface when rolled) of the lining sheet 25 and rolling it up. The lining sheet 25 may also have an overlap of 1 to 3 mm when rolled up, and this overlap is also glued and fixed. An example of the adhesive pattern of the lining sheet 25 is shown in Figure 17. In Figure 17, 25a shows the adhesive portion, and 25b shows the non-adhesive portion. Figure 17(a) shows a pattern where adhesive has been applied to the entire surface of the lining sheet 2. Figure 17(b) shows a pattern where a portion of the lining sheet 2 (the entire edge) has been glued. Figure 17(c) shows a pattern in which glue has been applied to a portion of the lining sheet 2 (the edge portion for fixing the overlapping portion of the lining sheet 2, and the internal portion for fixing multiple segments). Figure 17(d) shows a pattern in which glue has been applied to a portion of the lining sheet 2 (the edge portion for fixing the overlapping portion of the lining sheet 2, and the internal portion for fixing multiple segments).

[0104] <Modified example of lining sheet 2> The lining sheet 25 may be composed of multiple sheet materials (also simply referred to as "sheets"), and may be composed of two sheet materials or three or more sheet materials, but from the viewpoint of manufacturing cost, it is preferable to be composed of two sheets. When composed of multiple sheet materials, the configuration is not particularly limited, for example, each sheet material may be laminated so that a part of it overlaps, or it may be laminated so that the whole thing overlaps, but it is preferable to be formed to have a first sheet material (also simply referred to as "first sheet") and a second sheet material (also simply referred to as "second sheet") as described later. The conditions such as the material, shape, and properties of each sheet material can be those described in the above modification 1. In addition, the material, shape, and properties of each sheet material may be the same or different. Specifically, it is preferable that the sheet 25 is configured to include at least a first sheet and a second sheet positioned outside the first sheet and downstream. Furthermore, in an embodiment in which the mouthpiece segment 22 has a cooling segment 23 and a filter segment 24, and the cooling segment 23 is located upstream of the filter segment 24, it is more preferable that the lining sheet 25 is configured to include, as shown in Figures 18(a) to (d), at least a first sheet around which a portion of the flavor generating segment and a portion of the cooling segment are wound, and a second sheet located outside the first sheet around which at least all of the filter segment and a portion of the cooling segment are wound. In an embodiment like this, where multiple short segments are connected with a single type of lining sheet, misalignment of each segment occurs, but by connecting each segment in stages as in this embodiment, misalignment of each segment can be suppressed. Furthermore, a key requirement for the first sheet is to eliminate liquid permeability and block leakage or staining of the liquid contained in the filling 211 of the flavor-generating segment 21, while a key requirement for the second sheet is a comfortable grip and printability. The ability to individually select sheets that meet these requirements is also an advantage. Furthermore, if the non-combustion heating type flavor inhalation article 1 includes a tip segment 26 and a support segment 27, it may be configured to include a first sheet 28 on which the tip segment 26, flavor generating segment 21, and support segment 27 are wound, and a second sheet 29 on which the mouthpiece segment 22 is connected to the tip segment 26, flavor generating segment 21, and support segment 27 wound on the first sheet 28. The first sheet 28 may be made water-resistant and / or liquid-impermeable, and the second sheet may be a sheet with a surface suitability that is comfortable to hold or a sheet with a surface suitability that is good for printing.

[0105] When the second sheet is positioned as shown in Figures 18(a) to (d), it is preferable to use it with an electric heating device that is designed such as Figure 2, where at least two or more protrusions are provided on the side wall forming the recess 35 of the chamber, and at least two, preferably three, of these protrusions are provided so as to contact the second sheet when the non-combustible heated flavor inhalant article is inserted to the bottom surface, which is the deepest part of the recess. Specifically, in this configuration, when inserting the non-combustible heated tobacco into the recess of the electric heating device, the user can feel the contact or catch between the end face of the second sheet and the recess of the electric heating device, preventing the tobacco from being inserted more than necessary, and increasing the strength of the non-combustible heated tobacco being fixed by the protrusions. In addition, as shown in Figures 18(b) and (d), the lining sheet is wrapped around the entire non-combustible heated tobacco, which strengthens the rod strength of the non-combustible heated tobacco and prevents buckling damage to the tobacco when inserting or removing it from the recess of the heating device. Furthermore, it is possible to suppress the decrease in strength of the lining sheet due to the liquid components contained in the filling material of the flavor-generating segment, and also to suppress the decrease in strength due to heating during use (charring in the case of cellulose-based sheets, melting in the case of polymer-based sheets). If the strength of the lining sheet is low, it may tear when the non-combustion heated tobacco 2 is removed from the electric heating device after use, and some segments such as the flavor-generating segment may remain in the recess 35, so it is important to ensure the strength of the lining sheet.

[0106] The material, shape, characteristics, and other conditions of the first sheet 28 and the second sheet 29 are not particularly limited and can be similarly applied to the conditions of the lining sheet 25 described above, to the extent that they can be applied.

[0107] The thickness of the first sheet 28 is not particularly limited, but from the viewpoint of comfort in the hand and printability, it is usually 30 μm or more and 60 μm or less, and preferably 40 μm or more and 50 μm or less. The basis weight of the first sheet 28 is not particularly limited, but from the viewpoint of gripping comfort and printability, it is usually 30 gsm or more and 60 gsm or less, preferably 35 gsm or more and 50 gsm or less, and more preferably 35 gsm or more and 40 gsm or less. The air permeability of the first sheet 28 is not particularly limited, but from the viewpoint of grip comfort and printability, it is usually 0 Cholesta units or more and 30 Cholesta units or less, and preferably greater than 0 Cholesta units and 15 Cholesta units or less. The air permeability is a value measured in accordance with ISO 2965:2009, and is measured per minute over an area of ​​1 cm² when the differential pressure between both sides of the paper is 1 kPa. 2 Flow rate of gas passing through (cm 3 It is expressed as follows: 1 cholesta unit (1 cholesta unit, 1 C.U.) is equivalent to 1 cm at 1 kPa. 3 / (min·cm 2 ) The smoothness of the first sheet 28 is not particularly limited, but from the viewpoint of gripping comfort and printability, it is usually between 200 seconds and 1500 seconds, and between 250 seconds and 1000 seconds. It is preferable that the time is 300 seconds or more and 500 seconds or less. The opacity of the first sheet 28 is not particularly limited, but from the viewpoint of ensuring the desired appearance quality, it is usually 70% or more and 100% or less, preferably 75% or more and 95% or less, and more preferably 80% or more and 90% or less. From the viewpoint of being able to block leakage or staining of the liquid contained in the filling 211 of the flavor generating segment 21, the first sheet 25 is preferably a liquid-impermeable sheet, and for example, the liquid-impermeable material described above can be applied to it.

[0108] The thickness of the second sheet 29 is not particularly limited, but from the viewpoint of comfort in the hand and printability, it is usually 30 μm or more and 60 μm or less, and preferably 40 μm or more and 50 μm or less. The basis weight of the second sheet 29 is not particularly limited, but from the viewpoint of gripping comfort and printability, it is usually 30 gsm or more and 60 gsm or less, preferably 35 gsm or more and 50 gsm or less, and more preferably 35 gsm or more and 40 gsm or less. The air permeability of the second sheet 29 is not particularly limited, but from the viewpoint of grip comfort and printability, it is usually 0 Cholesta units or more and 30 Cholesta units or less, and preferably greater than 0 Cholesta units and 15 Cholesta units or less. The air permeability is a value measured in accordance with ISO 2965:2009, and is measured per minute over an area of ​​1 cm² when the differential pressure between both sides of the paper is 1 kPa. 2 Flow rate of gas passing through (cm 3 It is expressed as follows: 1 cholesta unit (1 cholesta unit, 1 C.U.) is equivalent to 1 cm at 1 kPa. 3 / (min·cm 2 ) The smoothness of the second sheet 29 is not particularly limited, but from the viewpoint of gripping comfort and printability, it is usually 200 seconds or more and 1500 seconds or less, preferably 250 seconds or more and 1000 seconds or less, and more preferably 300 seconds or more and 500 seconds or less. The opacity of the second sheet 29 is not particularly limited, but from the viewpoint of ensuring the desired appearance quality, it is usually 70% or more and 100% or less, preferably 75% or more and 95% or less, and more preferably 80% or more and 90% or less.
