In this embodiment, the regulating member 40 is In this case, it is formed in a substantially cylindrical shape and has one or more ventilation passages 41 that penetrate in the axial direction. Therefore, the regulating member has ventilation in the axial direction of the cover 10.

[0050] In this embodiment, the ventilation passage 41 is located on the outer circumferential surface of the regulating member 40, with equal spacing in the circumferential direction. The area is defined by four concave grooves formed at intervals and along the axial direction, and by the inner circumferential surface of the cover 10. It is being done.

[0051] Furthermore, the ventilation passage 41 penetrates axially, for example, from one end face to the other end face of the regulating member 40. The ventilation passage 41 may consist of one or more through holes formed to allow air to pass through. For example, a central ventilation passage formed along the axis of the regulating member 40, and surrounding this central ventilation passage Multiple vents are arranged in a circumferential direction and also formed to penetrate axially. It may also consist of road 41.

[0052] Furthermore, the regulating member 40 has a hexagonal end face shape and multiple ventilation passages that penetrate in the axial direction. It may be composed of a honeycomb structure or the like. Furthermore, the regulating member 40 may be, for example, a continuous air It may be composed of a porous body in which bubbles are formed.

[0053] The regulating member 40 is located on one or both axial end faces of the cover 10, preferably on the fragrance substrate 2. At the end face located on the 0 side, when the electrically heating means of the heated tobacco is inserted, the aromatic group It is preferable that the material 20 has a shape that can restrict the axial movement of the cover 10.

Also, if the melting point of the thermally fused material exceeds 100°C, the initial stage of the heating process of the fragrance base material The thermally fused material does not melt sufficiently in the first stage, and immediately after the heating process by heated tobacco ends, aerozo There is a tendency for the fragrance of the rue to be lacking.

[0080] Furthermore, the melting point of a thermally fused substance is, for example, that of paraffin wax as specified in JIS K2235. It can be measured in accordance with the melting point measurement method of S. That is, by using a predetermined melting point tester. Place the molten sample into a test tube and read the reading on the melting point thermometer every 15 seconds. The melting point is measured at the temperature when the temperature drop is within a certain range (when the difference is within 0.1°C for 5 consecutive times). It can be determined.

[0081] The thermally fused material is preferably in powder form. The average particle size of the thermally fused material is 125-35. It is preferably 5 μm, more preferably 150-300 μm, and 180- A particle size of 250 μm is even more preferable. The average particle size is determined, for example, by laser diffraction particle size analysis. It can be measured by a distribution measuring device, etc. In this invention, the average particle size is defined as med This refers to the diameter of Ahn.

[0082] If the average particle size of the thermally molten material is too large, its total surface area becomes small, thus reducing its contact with the heat source. The opportunity decreases. As a result, the thermally molten material is not sufficiently melted, and immediately after the end of the heating process... The concentration of aromatic components in aerosols tends to decrease.

[0083] If the outer diameter of the molten material is too small, the molten material will be dispersed in the aromatic substrate 20 described later, forming sea islands. It becomes difficult to form a structure. As a result, each of the thermally fused materials aggregates into a lump. Because it is present in the aromatic substrate 20, a region is created where the melting rate decreases upon contact with the heat source, and the temperature rises. The concentration of aromatic components in the aerosol tends to decrease immediately after the process is completed. (Thermal fusion properties) The quality is 2 to 20% by mass in the fragrance base material 20, preferably 3 to 15% by mass, more preferably It is preferable that it is contained in an amount of 5 to 15% by mass.

[0084] The proportions of fragrance source material, aerosol former, and heat-melting substance are determined by the volatilization of smoke and fragrance components. To balance the quantities, 55-75% by mass, 20-40% by mass, and 2-1% respectively. Preferably 5% by mass, 60-70% by mass, 25-35% by mass, 3-10% by mass It is preferable that it be so.

[0085] A thermally molten substance is a non-Newtonian fluid that, when heated, exhibits a melting point or softening point. The term is not particularly limited as long as it refers to "organic compounds that become waxy." Thermally molten substances are generally waxy. Organic compounds referred to as waxes are preferred, and typical examples of waxes and waxes are petroleum-based natural compounds. Waxes, synthetic waxes, plant-based natural waxes, and animal-based natural waxes can be used. Rosin, which is also used as a wax, is part of various tackifiers (adhesives). ) can be used. These can be used individually, or selected from among them. It can also be used as a mixture containing at least one of the following:

[0086] As a thermally molten substance, plant-based natural waxes and other materials are preferred due to their desirable melting point and flavor-enhancing properties. Animal-derived natural waxes are preferred. Examples of plant-derived natural waxes include sumac wax and lacquer wax. Carnauba wax, sugarcane wax, palm wax, candelilla wax, etc. can be used. In addition, natural animal waxes such as beeswax, whale wax, privet wax, wool wax, and shellac are used. This makes it possible to obtain materials with a melting point in the range of 50 to 100°C as defined in this invention. Furthermore, since it has a pleasant flavor of its own, it can enhance the aroma of the aerosol. Among these natural waxes, carnauba wax, beeswax, petrolatum, and paraffin wax are particularly noteworthy. Preferably, beeswax with a melting point of 62-65°C and rich in aromatic components is preferred.

[0087] Plant-based and animal-based natural waxes are mainly composed of esters of fatty acids and aliphatic alcohols. Yes. Plant-based and animal-based natural waxes are composed of fatty acids with various carbon numbers and aliphatic alcohols. It is a mixture of esters, and also contains free fatty acids and free aliphatic alcohols and hydrocarbons. Therefore, plant-based natural waxes and animal-based natural waxes have a wide molecular weight distribution and a wide melting point temperature. It has a wide temperature range and is characterized by high viscosity when melted.

[0088] Petroleum-based natural waxes are hydrocarbon compounds, therefore they contain aromatic components and aerosol forms. It has the advantage of having minimal interaction with other substances and being less likely to negatively affect flavor. Examples of waxes include petroleum jelly, paraffin wax, and microcrystalline wax. Camphor wood and the like can be used as preferred materials.

[0089] These petroleum-based natural waxes differ in their melting point temperature range based on their molecular structure. (Vaseline) It is a mixture of branched hydrocarbons and alicyclic hydrocarbons, with a melting point temperature range of 36-60°C. It's spacious. Paraffin wax is mainly composed of linear hydrocarbons, has high crystallinity, and is suitable for temperatures between 40 and 70°C. Most of them show a melting point, and the temperature range of the melting point is narrow.

[0090] Microcrystalline wax is a mixture of branched hydrocarbons and saturated cyclic hydrocarbons. Although it has low crystallinity, it has a high molecular weight and exhibits the highest melting point among these, at 60-90°C. Its melting point temperature range is also the second widest after petroleum jelly.

[0091] These petroleum-based natural waxes are all hydrocarbon compounds extracted from crude oil. Paraffin wax and microcrystalline wax have a melt viscosity and surface when heated and melted. It has low surface energy and minimal interaction with aromatic components and aerosols.

[0092] Examples of such paraffin waxes include the standard product manufactured by Nippon Seiro Co., Ltd. Paraffin Wax-115, 120, 125, 130, 135, 140, 145 There are 150 and 155, and all of them are preferably used. Also, special paraffin wax For example, high-purity refined paraffin wax, a special product manufactured by Nippon Seiro Co., Ltd. HNP series products, SP series products for specific applications, and isoparaffins manufactured using special methods EMW series products, which are the main component, are also preferably used. Furthermore, microcrystalline wax is, For example, any of the Hi-Mic series manufactured by Nippon Seiro Co., Ltd. is preferably used.

[0093] Examples of synthetic waxes include Fischer-Tropsch. Psch wax, polyethylene (PE) wax, modified PE wax, polypropylene PP wax, modified PP wax, fatty acid amide, fatty acid, aliphatic alcohol, PP Polyoxyalkylene glycol, polyoxyethylene alkyl ether, polyoxyethylene Lenalkylamines and the like can be preferably used.

[0094] In particular, Fischer-Tropsch wax is a linear hydrocarbon organic compound, It has low melt viscosity and surface energy during thermal melting, and is compatible with aerosol formers and aromatic components. The interaction is also small. As for Fischer-Tropsch wax, medium melting point products such as C80 (melt Temperatures such as (approximately 85-88°C) can be used.

[0095] Furthermore, PE wax and modified PE wax, and PP wax and modified PP wax Kus is also a hydrocarbon compound and can be preferably used.

"Viscol," etc., manufactured by BYK, "CERAFAK (registered trademark) 929, 950, 913, 9 14, 915, etc. can be preferably used.

[0096] In particular, metallocene catalyst polyolefin waxes are more preferred due to their narrow molecular weight distribution. For example, "Excellex (registered trademark)" manufactured by Mitsui Chemicals, Inc., which is a metallocene catalyst PE wax. "Standard" has a narrow molecular weight distribution and compositional distribution, and therefore has a melting point of 89-128°C, but is not suitable for hot melting. It has a low melt viscosity upon dissolution, making it an excellent polyolefin-based wax.

[0097] In addition to the above, other thermally fused substances include fatty acid amides, fatty acids, and aliphatic alcohols. Other types can also be used. Suitable fatty acid amides include monoamides and bisamides. Examples of monoamides include stearic acid monoamide, oleic acid monoamide, and erucic acid monoamide. The amide is preferred as it has a melting point of approximately 72 to 105°C.

The aromatic base material 20 can be made to contain the flavor of green tea leaves, etc. By containing nin, it suppresses the activity of the sympathetic nervous system in users who inhale the aerosol, leading to relaxation. It can be made to do that.

[0102] Theanine is found in 20 units of fragrance base in 100 units of one fragrance cartridge, which is beneficial for those with low anxiety tendencies. It is good to include 10-100mg of za to get a relaxing effect, and 20-80mg. It is preferable that it contains 30-60 mg, and more preferably that it contains 30-60 mg.

[0112] (Adsorbent) In this invention, the temperature of the fragrance substrate 20 is optimized for the volatilization of the aerosol former and fragrance source material. To prevent cooling agents and fragrances from volatilizing before reaching the desired temperature, an adsorbent is used. Good. As mentioned above, the adsorbent is used to add fragrances such as cooling agents and fragrances to the heated fragrance generating material 20. It can be made to stay there.

[0113] One preferred embodiment of the adsorbent is the fragrance generating substrate 2, which adsorbs the compound. An sorbent that causes the compound to adhere to 0 can be used. For example, if the compound is menthol In addition, menthol has a phenolic hydroxyl group. Therefore, as an sorbent, pheno For example, cross-linked polyvinylpyrrolidone (PVPP) is capable of adsorbing hydroxyl groups. Polyvinylpyrrolidone (PVP) Hydrophilic crosslinked polymers such as the above can be used.

[0114] Furthermore, for example, if the compound in question is nicotine, nicotine is a five-membered heterocyclic ring containing nitrogen. It has a compound of the formula. Therefore, as an sorbent, it is mutually exclusive with nitrogen-containing 5-membered heterocyclic compounds. Cross-linked PVP, which is thought to form an effect, can be used.

[0115] When cross-linked PVP and / or PVP is used as the adsorbent, the adsorbent is a fragrance source material, aerosol It is said to be contained in an amount of 4 to 25% by mass relative to 100% by mass of the total amount of the forma and thermally fused material. It is more preferable that it contains 5-20% by mass.

[0116] Furthermore, as an sorbent, the compound is adhering to the aroma-generating substrate 20 by encapsulating it. An adsorbent can be used, and such an adsorbent is cyclodextrin. It is possible.

[0117] Cyclodextrins are chemical substances containing hydroxyl groups and carboxyl groups of various sizes. It is known to form cyclodextrins, and among α, β, and γ-cyclodextrins, Displacement can also be used. In particular, β-cyclodextrin can be used with menthol and inclusion compounds. It forms a structure that is ideal as an sorbent for menthol.

[0118] When cyclodextrin is used as an adsorbent, the adsorbent is a fragrance source, aerosol former Furthermore, it is generally considered that the content is 0.1 to 1.2% by mass relative to 100% by mass of the total amount of thermally fused material. It is more preferable that it contains 0.2 to 1.0% by mass.

[0119] Furthermore, the adsorbent adsorbs and retains physiologically active substances such as catechins, caffeine, and theanine. It also plays a role in that. Furthermore, the sorbent contains both PVPP and cyclodextrin. preferable.

[0120] (Molding agent) The molding agent is used to reinforce the physical strength of the fragrance base material 20. The molding agent is: For example, cellulose fibers, microcrystalline cellulose, etc., can be used.

[0121] Examples of cellulose fibers include sugarcane, bamboo, wheat, rice, esparto, and jus. Cellulose fibers such as cellulose, hemp, and wood are preferably used. The fiber diameter is preferably 5 to 25 μm, and the fiber length is preferably 0.25 to 6 mm. By using cellulose fibers with fiber diameters and fiber lengths within such a range, the structure of the fragrance base material 20 This makes it possible to enhance the binding effect of the constituent components.

[0122] Furthermore, the microcrystalline cellulose preferably has an average particle size of 70 to 120 μm. When the average particle size of crystalline cellulose is less than 70 μm, shrinkage of the fragrance substrate 20 is suppressed and the fragrance group It tends to be difficult to prevent adhesion between material 20 and the molding machine. When the average particle size of the particles exceeds 120 μm, the fragrance substrate 20 tends to break easily. The average particle size of microcrystalline cellulose is measured using a laser diffraction particle size distribution analyzer. This is possible. In this invention, the average particle size refers to the median diameter.

[0123] Furthermore, the mass-average molecular weight (Mw) of microcrystalline cellulose is between 20,000 and 60,000. It is preferable that the mass-average molecular weight (Mw) of the microcrystalline cellulose is less than 20,000. If present, the effect of suppressing the shrinkage of the fragrance base material 20 tends to be diminished. Microcrystalline cellulose When the mass-average molecular weight (Mw) exceeds 60,000, the fragrance base material 20 becomes prone to breakage. There is a tendency.

[0124] The molding agent is composed of 100% by mass of the total amount of the fragrance source material, aerosol former, and thermally fused substance. It is good if it contains 2 to 25% by mass, preferably 3 to 20% by mass. By being contained in the fragrance base material 20 in this manner, the morphing agent performs the above functions. This prevents the molding agent from negatively impacting the generation of volatile substances from the fragrance source and aerosol former. It is possible.

[0125] (Binder) The binder is a raw material such as a fragrance source material that makes up the fragrance base, an aerosol former, or a thermally fused substance. It is used to bind materials together. Examples of binders include polysaccharide polymers and cellulose. Sodium polymers, calcium carbonate, and the like can be used.

[0126] Examples of polysaccharide polymers include konjac mannan (glucomannan) and guar gum. Ingredients: um, pectin, carrageenan, tamarind seed gum, acacia gum, soybean polysaccharides, locau Stovene gum, karaya gum, xanthan gum, agar, etc. can be used. Polysaccharides From the viewpoint of strength and the above-mentioned moldability, the polymers are glucomannan, guar gum, and pectin. Chin, carrageenan, tamarind seed gum, locust bean gum, karaya gum, and, Xanthan gum is preferred, along with neutral polysaccharides such as glucomannan, guar gum, and tamarind seed. Gum, and locust bean gum, are more preferred.

[0127] Examples of cellulose-based polymers include carboxymethylcellulose (CMC) and carboxymethylcellulose. carboxyethylcellulose, hydroxymethylcellulose, hydroxyethylcellulose, Hydroxypropylcellulose, sodium salt of CMC, potassium salt of CMC, CMC Calcium salt, sodium salt of carboxyethylcellulose, carboxyethylcellulose Potassium salts of cellulose, calcium salts of carboxyethylcellulose, etc., can be used. Cellulose polymers are considered to be the most suitable CMC in terms of the strength and moldability of the fragrance base material 20. Thorium salts, potassium salts of CMC, sodium salts of carboxyethylcellulose, carboxymethylcellulose Potassium salts of xyethylcellulose are preferred.

[0128] It is preferable to use a combination of polysaccharide-based polymers and cellulose-based polymers as binders. In this case, the polysaccharide polymers include glucomannan, guar gum, and tamarind gum. It is preferable to use locust bean gum. Furthermore, as a cellulose polymer, , sodium salt of CMC, potassium salt of CMC, sodium carboxyethylcellulose It is preferable to use potassium salts of carboxyethylcellulose. By using polysaccharide polymers and cellulose polymers in combination, the strength of the fragrance base material 20 and Furthermore, it is possible to improve the processability of the moldable parts.

[0129] The binder is applied to 100% by mass of the total amount of the fragrance source material, aerosol former, and thermally fused substance. It is preferable that it contains 5 to 30% by mass, and 8 to 28% by mass. This is more preferable. By including the binder in the fragrance base 20 in such a quantity, This improves the strength and moldability of the fragrance base material 20, and the fragrance source material and aerosol This helps to avoid adverse effects such as the generation of volatile substances from the foam.

[0130] Furthermore, the fragrance base material 20 of the present invention contains both a binder and a molding agent. This is preferable. In this case, the mixing ratio of the binder to the molding agent is 1:1 to 1:25 by mass. This is preferable in terms of cohesiveness.

[0131] (Preservative) To preserve heated fragrance-generating cartridges for extended periods, it is advisable to use preservatives. For example, potassium sorbate and / or sodium benzoate can be used as the agent. Yes, it is possible. The preservative consists of a total of 100g by mass of fragrance source material, aerosol former, and heat-melting substance. It is preferable that it contains 0.005 to 0.04 mass% relative to the total percentage.

[0132] Next, the manufacturing method of the fragrance base material 20 will be described. Figure 5 shows the manufacturing process of the fragrance base material 20. One embodiment is shown. As shown in Figure 5, the crushed and dried plant material that constitutes the fragrance This includes fragrance materials, flavor materials which are crushed and dried plant materials that make up the flavor, etc. Raw material (A) and raw material (B) including aromatic materials, which are pulverized and dried plant materials that make up the aroma. A mixing process is performed. The mixing process is carried out below the melting point of the thermally molten material. Mixing process This can be done, for example, using a known mixer.

[0133] Raw material (A) contains fragrance material, which is a crushed and dried product of plants that make up the fragrance. Raw materials (A1), flavor material which is a pulverized and dried product of plants that make up the flavor, and heat melting Raw materials containing the substance (A2), an alcoholic aqueous solution of microcrystalline cellulose, and an alcoholic binder. Raw materials (A3) containing an aqueous solution of alcohol and an aqueous solution of sorbent, and aerosol form This is obtained by mixing raw materials (A4) containing fragrances and molding agents and allowing them to mature. .

[0134] Furthermore, the mixing of raw materials (A1) to (A4) should be carried out below the melting point of the thermally fused substances. This mixing process can be carried out, for example, using a known mixer.

[0135] The raw material (A1) is obtained by pulverizing the fragrance material after sterilization.

[0136] The raw material (A2) is obtained by pulverizing the mixture of the flavor material and the heat-melting substance after sterilization. Specifically, as shown in FIG. 6, after sterilizing the flavor material, it is pulverized to a predetermined size. Also, the powdery heat-melting substance is heated and mixed above the melting point of the heat-melting substance and then cooled, and then pulverized to a predetermined size. The pulverized product and the powdery flavor material are compression-shear mixed, cooled, and then pulverized to prepare the raw material (A2). It is preferable.

[0137] The raw material (A3) is obtained by mixing an aqueous alcohol solution of microcrystalline cellulose, an aqueous alcohol solution of a binder, and an aqueous alcohol solution of a sorbent (crosslinked polyvinylpyrrolidone and / or polyvinylpyrrolidone). The aqueous alcohol solution is a mixture of pure water and ethanol.

[0138] The raw material (A4) is obtained by mixing an aerosol former, a fragrance, and a molding agent. It is obtained.

[0139] Aging is preferably carried out for 3 to 14 days under temperature conditions of, for example, 15 to 30°C. Aging is more preferably carried out for 4 to 7 days under temperature conditions of 20 ± ^{\circ}C from the viewpoint of retaining the aromatic components. If the temperature exceeds 30°C or the aging period exceeds 14 days, the tendency for mold growth and corruption increases.

[0140] The raw material (B) is obtained by mixing the raw material (B1) containing an aroma material which is a pulverized and dried product of a plant constituting the aroma and the raw material (B2) containing a preservative. Note that the raw material (B1) The mixing of (B2) and (B2) can be carried out, for example, using a known mixer.

[0141] The raw material (B1) is obtained by sterilizing and then grinding the aromatic material. The raw material (B2) is obtained by dissolving a preservative in pure water.

[0142] By performing a mixing process in which raw material (A) and raw material (B) are mixed in this manner, the aroma is produced. A sea-island structure is formed in which powder of a heat-melted substance mixed with fragrance source material is dispersed on the fragrance base material 20. It is possible.

[0143] The mixture obtained in this way is granulated. The average particle size of the mixture is determined by laser diffraction particle size analysis. It can be measured by a distribution measuring device. The average particle size of the mixture in this invention is This refers to the diameter of the granulated fragrance base material 20. The aromatic base material 20 is formed by mixing the gaseous material 22.

[0144] Thus, the mixing process, compression / shearing process, and cutting process are carried out below the melting point of the thermally molten material. This prevents the melting of the thermally fused material from spreading throughout the entire fragrance base material 20, thus preventing the fragrance from spreading. This makes it possible to maintain the sea-island structure of the thermally fused material in the substrate 20.

[0145] A sea-island structure is formed in which powder of a heat-melted substance mixed with fragrance source material is dispersed on the fragrance base material 20. As a result, the heat-melting substance is dispersed on the fragrance base material 20 in an island-like manner.

[0146] The heat-melted substance separates into island-like structures on the fragrance substrate 20, more so than when it is impregnated into the fragrance source material. When the materials are dispersed, they become more fluid when melted, and the aromatic components released from the aromatic source material are released. It becomes easier to contain. Further, the flowing heat-melted substance contacts the aerosol former, and the aromatic component can be made to easily volatilize as an aerosol together with the aerosol former. .

[0147] As a result, it is possible to efficiently volatilize the aromatic component of the aromatic source material. Therefore, the user can more fully enjoy the aroma when inhaling the aerosol emitted from the aromatic cartridge 100 immediately after the end of the temperature rise process of the heated tobacco.

[0148] Incidentally, the heat-melted substance may be added to the raw material (B). FIG. 7 shows another embodiment of the manufacturing process of the aromatic base material 20. As shown in FIG. 7, when adding the heat-melted substance to the raw material (B), for example, it may be added to the raw material (B1). "

[0149] As described above, according to the aromatic cartridge 100 of the present invention, it is possible to reduce the ventilation resistance in the axial direction of the cover 10. For this reason, it is possible to improve the ease of inhaling the aerosol generated from the aromatic base material 20. Further, since the aerosol and air can be mixed in an appropriate distribution, it is possible to improve the flavor. "

[0150] [Embodiment 2] FIG. 8 shows the aromatic cartridge 100 of Embodiment 2. This aromatic cartridge 100 has a ventilation member 23 different from that of the aromatic cartridge 100 of Embodiment 1. For the same configuration as that of the aromatic cartridge 100 of Embodiment 1, the same reference numerals are assigned to the same parts and the description thereof is omitted. ]As shown in FIG. 8, in this aromatic cartridge 100, the ventilation member 23 disposed between the aromatic base materials 20 is different from that of the aromatic cartridge 100 of Embodiment 1.

[0151] [[ID=X5]] As shown in FIG. 8, in this aromatic cartridge 100, the ventilation member 23 disposed between the aromatic base materials 20 is As the ventilation member 23, granular pumice, which is a porous inorganic material, is used. By using stone, heat resistance and rigidity can be increased.

[0152] [Embodiment 3] Figure 9 shows the fragrance cartridge 100 of Embodiment 3. In embodiment 100, the ventilation member 24 differs from that of the fragrance cartridge 100 in embodiment 1. For components identical to fragrance cartridge 100, the same reference numerals are used to indicate the same location. I will omit the explanation.

[0153] As shown in Figure 9, in this fragrance cartridge 100, the ventilation member 2 of the fragrance base material 20 4. It is formed from at least one type of fiber selected from cotton, wool, nonwoven fabric, etc. A sheet piece with good breathability is used. Multiple sheets formed by these fibers The pods are dispersed and arranged among the constituent elements 21 of the fragrance base material 20.

[0154] [Embodiment 4] Figure 10 shows the fragrance cartridge 100 of Embodiment 4. The shape of the component 21 of the fragrance base material 20 is the same as that of the fragrance cartridge 10 of Embodiment 1. It is different from 0. For the same configuration as the fragrance cartridge 100 of Embodiment 1, the same part The same symbol is used in the location, and the explanation is omitted.

[0155] As shown in Figure 10, the constituent elements 21 of the fragrance base material 20 are formed in the shape of strips (sheets). In other words, the fragrance base material 20 is composed of multiple strip-shaped (sheet-shaped) components 21. It is formed into a roughly cylindrical shape.

[0156] The components 21 of such fragrance base material 20 undergo the following processing after the raw materials are mixed. It can be formed by compressing the mixture obtained in the mixing process. The material is cut and formed into a sheet. In compression and shearing processes, for example, This can be done using a three-roller system. Compression and shearing are performed using a three-roller system. This allows it to be molded into a sheet shape by incorporating air and evaporating water.

[0157] The sheet obtained in this way has a porous structure that contains air inside. As a result, it becomes possible to obtain a low-density aromatic substrate 20. Also, 3 roll Because the roll has an extremely flat surface, the surface of the sheet is formed flat.

[0158] In other words, the fragrance base material 20, during compression and shearing, becomes porous, containing air inside. Because it has a structure, it has a low density, and its surface is formed to be flat without any irregularities.

[0159] The mixture, formed into a sheet by compression and shearing, is cut to a predetermined shape and size. The mixture is cut and then processed into strips, for example.

[0160] [Embodiment 5] Figures 11 and 12 show the fragrance cartridge 100 of Embodiment 5. The cartridge 100 has the same form as the fragrance base material 20 and ventilation member as the fragrance cartridge of Embodiment 1. This is different from the 100. Regarding the same configuration as the fragrance cartridge 100 of Embodiment 1, The same symbol is used in the same location, and the explanation is omitted.

[0161] As shown in Figure 11, the fragrance substrate 20 consists of its constituent elements 21 and the ventilation member 25. Formed into a sheet shape, with both sheets stacked, from one end to the other end It is formed into a roughly cylindrical shape by winding it. That is, one end face of the fragrance base material 20 From this perspective, the sheet which is a component 21 of the fragrance base material 20 and the sheet of the ventilation member 25 are, They are formed in a spiral shape, overlapping each other.

[0162] The ventilation member 25 is a spirally wound sheet, and the fragrance base material is also spirally wound. Since it is placed between the sheets of the 20 components 21, axial ventilation is possible via the ventilation member 25. The properties can be improved. The sheet thickness of the component 21 of the fragrance base material 20 and the ventilation member 25 The ratio of the sheet thickness to the material is preferably in the range of 1:1 to 1:3, or 1.0:1.5 to 1. A range of 0:2.0 is even more preferable.

[0163] As shown in Figure 12, in this embodiment, the sheet of the component 21 of the fragrance base material 20 and Each sheet of the gas member 25 is made up of a single sheet, but is divided in the axial direction. It may consist of multiple sheets.

[0164] [Embodiment 6] Figure 13 shows the fragrance cartridge 100 of Embodiment 6. The shape of the ventilation member in the 1st embodiment of the fragrance cartridge 100 differs from that of the 1st embodiment. For components identical to the fragrance cartridge 100 of Form 1, the same reference numerals are used for the same locations. Therefore, the explanation will be omitted.

[0165] As shown in Figure 13, the ventilation member 26 of the fragrance base material 20 has multiple protrusions on the surface of the spherical particles It is formed, for example, having a shape like a konpeito (sugar candy). According to this ventilation member 26, the surface Multiple formed protrusions come into contact with adjacent granular fragrance substrates 20, allowing the ventilation member 26 to release fragrance. A gap is formed between the substrate 20 and the structure, and this gap forms a ventilation passage. In this invention, the "breathable member having breathability" is only breathable if it is itself breathable. This also includes cases where voids are formed by protrusions or other features on the surface. [Examples]

[0166] [Test Example 1] (Sensory evaluation of breathability) The aromatic base material 20 consists of granular components and the breathable member 22 is formed in a cotton-like manner. An aromatic cartridge 100, which is placed between the constituent elements, was created as Example 1, and the granular constituent A fragrance cartridge in which the fragrance base material 20 is provided over the entire heating region R1 was prepared as Comparative Example 1. The aerosol permeability of both materials was then evaluated.

[0167] (Sample preparation: Example 1, Example 2, Comparative Example 1) Example 1 involved forming the fragrance base material 20 into granules using the formulation shown in Table 1, and forming the fragrance base material 20 into a sheet. Fragrance cartridges 100 of the formed Example 2 and Comparative Example 1 were prepared. Specifically, fragrance Source materials (aroma materials, fragrance materials and flavor materials), aerosol formers and thermally fused substances The following formulation was used as the basic formulation. In Examples 1 and 2 and Comparative Example 1, the basic formulation used the fragrance source material The composition was 65% by mass of the aerosol former, 25% by mass of the thermally fused material, and 10% by mass of the thermally fused material.

[0168] For every 100 parts by mass of the basic formulation, add 15 parts by mass of fragrance, 23 parts by mass of binder, and sorbent. Add 21 parts by mass, 0.005 parts by mass of preservative, and 20 parts by mass of pure water to obtain the aromatic compound from Example 1. Cartridge 100 was created. Note that pure water is added for the molding process, but after the molding process... It is removed from the fragrance base material by drying.

[0169] [Table 1]

[0170] The aromatic materials are konjac powder as the aromatic material of raw material (B1) and fragrance of raw material (A1). Black tea and osmanthus flowers were used as the base material, and Gynostemma pentaphyllum was used as the flavoring material for the raw material (A3).

[0171] The aerosol former (A4) used as the raw material consisted of glycerin and propylene glycol. Beeswax was used as the thermally melted substance for raw material (A2). The fragrance used as raw material (A4) consisted of peppermint oil and menthol. The binders used in raw material (A3) were CMC sodium salt and sugarcane fiber. The sorbents used for raw material (A3) were cross-linked polyvinylpyrrolidone and β-cyclodextrin. The preservatives used in raw material (B2) were potassium sorbate and sodium benzoate.

[0172] Raw materials (A1) and (A2) were prepared in the manner shown in Figure 6. Specifically, raw material (A1 The fragrance material was obtained by sterilizing and then grinding it into a powder. The raw material (A2) is Fragrance The material (manufactured by YUNNAN HANSU BIOTECHNOLOGY CO.,LTD, Production code: PR001) and a thermally fused substance were roughly mixed in a Henschel mixer, then compressed and sheared, and cooled to below 0°C. It was later crushed and prepared. In addition, raw materials (A1) and (A2) were sieved through an 80-mesh sieve. The sample used was selected to have an average particle size of approximately 250 μm.

[0173] Furthermore, in the embodiments shown in Figures 5 and 6, raw materials (A) and (B) are used to create a fragrance cartridge 1 00 was produced. Specifically, a mixing process was performed in which raw materials (A) and (B) were mixed using a kneader. They did that.

[0174] In addition, in Example 1, the crushed raw material was impregnated with an aroma agent and a heat-melting substance, and averaged The mixture was granulated so that the particle size was between 0.1 mm and 1.5 mm. The shape is not important as long as the volume falls within the range of the average particle size mentioned above, even if it is not a sphere.

[0175] Next, in Example 2 and Comparative Example 1, the mixture was formed into a sheet using three rolls. A compression and shearing process was performed to shape the material. In the compression and shearing process, the thickness was reduced to 0.28 ± 0.02 m. The material was formed into a sheet with a length of m. The compression and shearing processes were carried out below the melting point of the beeswax.

[0176] The components 21 of the fragrance base material 20 obtained in this way are mixed with the cotton-like breathable member 22. A fragrance base material 20 was formed. The ratio of the volume of the fragrance base material 20 to the volume of the breathable member 22 It was set at 5:1.

[0177] (Sensory evaluation) Using heated tobacco, the aerosol of the fragrance cartridge 100 of Example 1 and Comparative Example 1 The flavor was evaluated by 10 panelists.

[0178] Eight of the ten panelists used the fragrance cartridges 100 of Examples 1 and 2. However, it has better breathability and a better smoking sensation (better aroma) than the fragrance cartridge 100 of Comparative Example 1. It was evaluated that the desired flavor was obtained.

[0179] Furthermore, eight of the ten panelists used the fragrance cartridge 100 of Example 1. However, it has better breathability and a better smoking sensation (good aroma) than the fragrance cartridge 100 of Example 2. It was evaluated that the desired flavor was obtained.
