[0005] Incidentally, the aroma cartridge can take various forms depending on the specifications of the inhalation device. For example, the aroma cartridge is often formed in a cylindrical shape, but the electric heating means is Inhalation devices that are shaped like a rod or pin generate aerosols by heating. The diameter of the aroma cartridge is set so that the electrical heating means can be inserted into the aroma base material.

[0006] In response to this, the electric heating means is formed in a cylindrical shape or the like so as to be able to heat the outer circumferential surface of the aroma cartridge. In the inhalation device constructed in the present invention, it is not necessary to insert an electric heating means into the fragrance base material. Therefore, the diameter of the aroma cartridge is smaller than that of the aroma cartridge used in the inhalation device formed in the blade shape, etc. It is possible to set it small.

[0007] Regardless of the form of the aroma cartridge, the smoking sensation and smoking time are consistent. For this reason, the fragrance base material that generates the aerosol is placed in the fragrance cartridge. It is preferable that the amount of the ridges to be filled is at least a certain amount regardless of the shape of the aroma cartridge. .

The partition 40 has air permeability in the axial direction of the cover 10. The material may have any suitable breathability for smoking, for example, at least the same breathability as the filter 30. It is preferable that the material has a certain degree of breathability.

[0038] In this embodiment, the partition wall 40 has a through hole formed from one end to the other end. It is formed in a hollow cylindrical shape having a through hole 41, but it is formed in a cylindrical shape without a through hole 41. The partition 40 may be made of a material that is heated by an electrical heating means of the heated tobacco product.

[0054] (Aerosol former) The aerosol former generates an aerosol when the fragrance base material 20 is heated. Examples of aerosol formers include glycerin, propylene glycol, and the like. ethanol, sorbitol, triethylene glycol, lactic acid, diacetin (glycerin diacetate (glycerin triacetate), triacetin (glycerin triacetate), triethylene glycol diacetate , triethyl citrate, isopropyl myristate, methyl stearate, dodecane Dimethyl tetradecanedione, dimethyl tetradecanedione, etc. can be used, but especially glycerol is preferred. Serine and propylene glycol are preferably used.

[0055] (Thermal melting material) The heat-meltable substance melts at a relatively low temperature and dissolves the aromatic components generated from the aromatic base material 20. It is added to make it easier for the aerosol former to be vaporized and dispersed together with the aerosol former. In addition, the heat-fusible substance also plays a role in fixing the fragrance source material and / or the fragrance at room temperature.

[0056] The melting point of the heat-melting substance is in the range of 50 to 100°C, preferably in the range of 50 to 80°C. The melting point of the heat-fusible substance is preferably in the range of 60 to 67°C. If the product is too hot, the heat-melting substance may melt and become sticky during hot periods such as summer. In addition, when the melting point of the heat-melting substance exceeds 100°C, the aroma base material is heated in the early stage. The heat-fusible substance is not fully melted at this stage, and the aerosol immediately after the heating process by the heated tobacco is completed The fragrance of the product tends to be lacking.

[0057] The melting point of the heat-melting substance is, for example, the paraffin wax specified in JIS K2235. The melting point can be measured in accordance with the melting point measurement method of the standard. The melted sample is placed in a test tube, and the melting point thermometer is read every 15 seconds. The temperature at which the drop is within a certain range (a difference of 0.1°C or less five times in a row) is measured as the melting point. It can be determined.

[0058] The heat-melting substance is preferably in powder form. The average particle size of the heat-melting substance is 125 to 35. It is preferably 5 μm, more preferably 150 to 300 μm, and more preferably 180 to It is even more preferable that the average particle size is 250 μm. The average particle size is, for example, measured by a laser diffraction particle sizer. The average particle size in the present invention can be measured by a distribution measuring device. This means the Anne diameter.

[0059] If the average particle size of the heat-melting material is too large, the total surface area will be small, and the contact with the heat source will be As a result, the heat-melting material is not melted sufficiently, and the The concentration of the fragrance components in the aerosol tends to decrease.

[0060] If the outer diameter of the thermally fusible substance is too small, the thermally fusible substance may be dispersed in islands in the fragrance base material 20 described later. As a result, it becomes difficult to form a structure. Because of the presence of the aromatic base material 20, a region is formed in which the melting rate upon contact with a heat source is reduced, and the temperature rises The concentration of the aromatic component in the aerosol immediately after the process tends to decrease. The content of the aromatic base material 20 is 2 to 20% by mass, preferably 3 to 15% by mass, and more preferably The content is preferably 5 to 15 mass %.

[0061] The blending amounts of the aroma source material, aerosol former and thermal melting substance are determined based on the volatilization of smoke components and aroma components. To balance the amounts, 55-75% by weight, 20-40% by weight, and 2-1 5% by mass is preferable, 60 to 70% by mass, 25 to 35% by mass, 3 to 10% by mass It is more preferable that:

[0062] A thermally melting substance is a substance that "displays a melting point or softening point when heated and is a non-Newtonian fluid." The heat-melting substance is not particularly limited as long as it is an organic compound that melts the material. Preferred are organic compounds called waxes and petroleum-based natural compounds. Wax, synthetic wax, natural plant wax and natural animal wax can be used. Various tackifiers (tackifiers) including rosin, which is also used as wax ) can be used. These can be used alone or in combination. It is also possible to use a mixture containing at least one of the above.

[0063] As the heat-melting substance, natural wax from plants or the like is preferred because it has a preferable melting point and can impart flavor. Natural animal waxes are preferably used. Natural plant waxes include, for example, wax of Japanese laurel and lacquer wax. Examples of wax that can be used include carnauba wax, sugarcane wax, palm wax, and candelilla wax. In addition, natural animal waxes such as beeswax, spermaceti, privet wax, wool wax, and shellac can be used. These can be easily obtained with a melting point in the range of 50 to 100°C as specified in the present invention. In addition, since it has a pleasant flavor, it can enhance the aroma of the aerosol. Among these natural waxes, carnauba wax, beeswax, petrolatum, and paraffin wax are particularly Beeswax, which has a melting point of 62 to 65° C. and is rich in aromatic components, is most preferable.

[0064] Natural plant waxes and natural animal waxes are mainly composed of esters of fatty acids and fatty alcohols. Natural plant waxes and natural animal waxes are made up of fatty acids with various carbon numbers and fatty alcohols. It is a mixture of esters, including free fatty acids, free fatty alcohols, and hydrocarbons. Therefore, natural plant waxes and natural animal waxes have a wide molecular weight distribution and a wide melting point. It has a wide viscosity range and is characterized by high melting viscosity.

[0065] Petroleum-based natural waxes are hydrocarbon compounds, so they contain aromatic components and aerosol formers. It has the advantage of being less likely to interact with other substances and less likely to adversely affect the flavor. Examples of waxes include petrolatum, paraffin wax, and microcrystalline wax. Preferably, the above-mentioned materials can be used.

[0066] These petroleum-based natural waxes have different melting points based on their molecular structure. is a mixture of branched and alicyclic hydrocarbons, with a melting point range of 36 to 60°C. It is spacious. Paraffin wax is mainly composed of linear hydrocarbons, has high crystallinity, and is stable at temperatures between 40 and 70°C. Most of them have a melting point of 0.01 mm or less, and the melting point temperature range is narrow.

[0067] Microcrystalline wax is a mixture of branched and saturated cyclic hydrocarbons. It has low crystallinity but a high molecular weight and has the highest melting point of 60 to 90°C. The range of melting points is also the second widest after Vaseline.

[0068] All of these petroleum-based natural waxes are hydrocarbon compounds extracted from crude oil. Paraffin wax and microcrystalline wax have high melt viscosity and surface area when melted by heat. It has low surface energy and also has little interaction with aromatic components and aerosol formers.

[0089] (sorbent) In the present invention, the temperature of the fragrance substrate 20 is set to an optimum temperature at which the aerosol former and the fragrance source material volatilize. If an absorbent is used to prevent fresheners and fragrances from evaporating before the temperature reaches the limit, As described above, the sorption agent is a material for adding a fragrance such as a cooling agent or a perfume to the heated aroma generating material 20. It can be allowed to stay.

[0090] As a preferred embodiment of the sorbent, the compound is adsorbed to produce an aroma-generating substrate 2. For example, if the compound is menthol, In this case, menthol has a phenolic hydroxyl group. For example, cross-linked polyvinylpyrrolidone (PVPP) capable of adsorbing alkyl hydroxyl groups. Polyvinylpolypyrrolidone), Polyvinylpyrrolidone (PVP) Hydrophilic crosslinked polymers such as the above can be used.

[0091] Also, for example, when the compound is nicotine, nicotine has a five-membered nitrogen-containing heterocycle. Therefore, as a sorbent, it has a mutual interaction with five-membered heterocyclic compounds containing nitrogen. Crosslinked PVP may be used, which is believed to form the effect.

[0092] When crosslinked PVP and / or PVP is used as the sorbent, the sorbent is a fragrance source material, aerosol The content is 4 to 25% by mass relative to 100% by mass of the total amount of the former and the heat-melting substance. It is more preferable that the content is 5 to 20 mass %.

When the average particle size of the crystalline cellulose is less than 70 μm, the shrinkage of the aromatic base material 20 is suppressed and the aromatic group is easily absorbed. It tends to be difficult to prevent adhesion between the material 20 and the molding machine. If the average particle size of the powder exceeds 120 μm, the aromatic base material 20 tends to break easily. The average particle size of the microcrystalline cellulose is measured by a laser diffraction particle size distribution measuring device. In the present invention, the average particle size means the median diameter.

The preservative is not to be used in the amount of 100% by weight of the total of the fragrance source material, the aerosol former, and the heat melting substance. %, it is preferable that the content is 0.005 to 0.04 mass %.

[0109] Next, a method for producing the fragrant base material 20 will be described. As shown in FIG. 5, the dried plant material constituting the fragrance is crushed and dried. and flavoring materials which are crushed and dried plants that constitute the flavor. Raw material (A) and raw material (B) containing aromatic materials, etc., which are crushed and dried plants that constitute aroma, are mixed together. A mixing step of mixing is performed. The mixing step is performed below the melting point of the heat melting material. This can be carried out, for example, using a known mixer.

[0110] Raw material (A) contains fragrance materials, which are crushed and dried plants that make up the fragrance. The raw material (A1) is a flavoring material which is a ground and dried product of a plant which constitutes the flavoring material, and A raw material containing the substance (A2), an alcohol-water solution of microcrystalline cellulose, and an alcohol-based binder. A raw material (A3) containing an aqueous solution of sorbent and an aqueous alcohol solution of the sorbent and an aerosol former (A4) containing the aromatic agent and the molding agent, and then aging the mixture. .

[0111] The raw materials (A1) to (A4) are mixed at a temperature lower than the melting point of the heat-melting substance. This mixing step can be carried out, for example, using a known mixer.

[0112] The raw material (A1) is obtained by sterilizing a fragrance material and then pulverizing it.

[0113] The raw material (A2) is a mixture of flavoring materials and heat-melting substances that is sterilized and then crushed. Specifically, as shown in FIG. 6, the flavoring material is sterilized and then cut into pieces of a predetermined size. The powdered heat-fusible substance is heated and mixed at a temperature equal to or higher than the melting point of the heat-fusible substance. After cooling, it is crushed to a predetermined size. The crushed product and the powdered flavoring material are mixed. The mixture is compressed and sheared, cooled, and then crushed to prepare raw material (A2). stomach.

[0114] The raw material (A3) is an alcoholic solution of microcrystalline cellulose, an alcoholic solution of a binder, and and sorbent (crosslinked polyvinylpyrrolidone and / or polyvinylpyrrolidone) in alcohol water The alcohol solution is obtained by mixing the solutions. The alcohol solution is a mixture of pure water and ethanol.

[0115] Raw material (A4) is obtained by mixing an aerosol former, an aromatic agent, and a molding agent. do.

[0116] The aging is preferably carried out, for example, at a temperature of 15 to 30° C. for 3 to 14 days. From the viewpoint of preserving the aromatic components, it is recommended to carry out the storage at a temperature of 20±2℃ for 4 to 7 days. If the temperature exceeds 30°C or the maturation period exceeds 14 days, mold may develop and There is a tendency for corruption to increase.

[0117] The raw material (B) is a raw material containing aromatic materials, which are crushed and dried plants that constitute aromas (B The raw material (B1) is mixed with raw material (B2) containing a preservative. The mixing of (B1) and (B2) can be carried out, for example, by using a known mixer.

[0118] The raw material (B1) is obtained by sterilizing aromatic materials and then crushing them. The raw material (B2) is obtained by dissolving a preservative in pure water.

[0119] By carrying out the mixing step of mixing the raw materials (A) and (B) in this manner, the aromatic Forming a sea-island structure in which powder of a heat-melting substance mixed with a fragrance source material is dispersed in the fragrance base material 20 can be done.

[0120] Next, the mixture obtained in the mixing step is compressed and sheared to form it into a sheet. Compression and shear processing can be carried out, for example, using three rolls. By compressing and shearing with three rolls, air is trapped and water is prevented from evaporating. It can be formed into a sheet.

[0121] The sheet obtained in this manner has a porous structure containing air inside. As a result, it is possible to obtain a low-density fragrance base material 20. Since the roll has an extremely flat surface, the surface of the sheet is formed flat.

[0122] That is, the aromatic base material 20 becomes porous and contains air inside during compression and shear processing. Since it has a structure, it has a low density and its surface is flat and free of irregularities. .

[0123] The mixture formed into a sheet by compression and shear processing is cut into a desired shape and size. The mixture in sheet form is then cut into strips, for example.

[0124] In this way, the mixing process, compression / shear process and cutting process are carried out below the melting point of the heat-melting substance. By using the heat-melting material, the melting of the heat-melting material is prevented from spreading throughout the fragrance base material 20, and the fragrance It is possible to maintain the sea-island structure of the thermally fusible substance in the substrate 20.

[0125] The fragrance base material 20 has a sea-island structure in which the powder of the heat-melting material mixed with the fragrance source material is dispersed. When this is done, the thermally meltable substance is dispersed and arranged in the aroma base material 20 in the form of islands.

[0126] The thermally meltable substance is distributed in the aroma base material 20 in the form of islands, rather than being impregnated in the aroma source material. The more dispersed the material is, the easier it will flow when melted, and the more aromatic components will be released from the fragrance source material. In addition, the flowing heat-melting material comes into contact with the aerosol former, and the aromatic The fragrance ingredients can be made into an aerosol together with the aerosol former, making it easier to volatilize. .

[0127] As a result, it is possible to efficiently volatilize the aromatic components of the aromatic source material. The laser was used to measure the amount of aroma emitted from the aroma cartridge 100 immediately after the end of the heating process of the heated tobacco product. When the aerosol is inhaled, the aroma can be enjoyed more fully.

[0128] The thermally fusible substance may be added to the raw material (B). Another embodiment of the manufacturing process is shown in FIG. When the substance is added to raw material (B), it is advisable to add it to raw material (B1), for example.

[0129] As described above, according to the aroma cartridge 100 of the present invention, the axial direction of the cover 10 Therefore, it is possible to reduce the airflow resistance generated by the aromatic substrate 20. It is possible to improve the ease of inhaling the sol. In addition, the aerosol and air can be appropriately distributed. Since the ingredients can be mixed at a temperature of 100° C., it is possible to improve the flavor.

[0136] The restricting member 60 is formed in this manner, so that the restricting member 60 is In other words, the restricting member 60 supports the fragrant base material 20. This can be done.

[0137] In addition, the restricting member 60 restricts the aerosol containing the aromatic component generated from the aromatic base material 20. When the aerosol passes through the restricting member 60, the aerosol can be cooled. The aroma cartridge 100 is heated to a temperature that is high enough to withstand the heat. For example, the aroma cartridge 100 is a cartridge for a heated tobacco product. In this case, the regulating member 60 is formed of a material having a heat resistance of about 180 to 400° C. good.

When the aroma cartridge 100 is attached to the heat-not-burn cigarette 50, the aroma cartridge 100 is heated by the electric heating means 52. The scented substrate 20 can be held in a position suitable for heating.

[0142] [Embodiment 3] In the aroma cartridge 100 of the third embodiment, the aroma base material 20 flows out from the cover 10. The aroma cartridge 100 of the first and second embodiments differs from the aroma cartridge 100 of the first and second embodiments in that a lid material is used to prevent this. The same configurations as those of the aroma cartridge 100 of the first and second embodiments are the same in the same locations. The following symbols are used and their explanations are omitted.

[0155] The aerosol former of raw material (A4) was made using glycerin and propylene glycol. . Beeswax was used as the heat-melting substance of raw material (A2). As the aromatic raw material (A4), peppermint oil and menthol were used. The binder for the raw material (A3) was CMC sodium salt and sugarcane fiber. The sorbent for the raw material (A3) is cross-linked polyvinylpyrrolidone and β-cyclodextrin. there was. The preservatives used in raw material (B2) were potassium sorbate and sodium benzoate.

[0156] The raw materials (A1) and (A2) were prepared in the manner shown in FIG. The fragrance material was obtained by sterilizing it and then grinding it into powder. Material, (YUNNAN HANSU BIOTECHNOLOGY CO.,LTD, Production code: PR001) and heat fusion The materials were roughly mixed in a Henschel mixer, then compressed and sheared to mix, and cooled to below 0°C. The raw materials (A1) and (A2) were sieved through an 80 mesh sieve. The particles were selected to have an average particle size of about 250 μm.

[0157] In addition, in the embodiment shown in Figs. 5 and 6, the raw materials (A) and (B) are used to prepare the aroma cartridge 1. Specifically, the raw materials (A) and (B) were mixed in a kneader. was carried out.

[0158] In Example 1 and Comparative Example 1, the mixture was then formed into a sheet using a three-roll mill. In the compression and shear process, the thickness was 0.28±0.02m. The compression and shearing process was carried out below the melting point of beeswax.

[0159] Then, a cutting process was carried out to cut the sheet. The width of the sample was 1.5±0.1 mm and the length was about 240 mm. The sheet was cut to a size of 1.5±0.1 mm and a length of approximately 240 mm.

[0160] In Example 2, the crushed raw material was impregnated with an aroma agent or a heat-melting substance, and the average The mixture was granulated to a particle size of 0.1 mm to 1.5 mm. The shape is not important as long as it is not spherical and has a volume within the range of the average particle size mentioned above. The average particle size of the mixture can be measured by a laser diffraction particle size distribution measuring device. In the present specification, the average particle size of the mixture means the median diameter.

[0161] The aromatic base material thus obtained was wrapped in paper to a predetermined packing ratio. For Examples 1 and 2, the length of each fragrance base material was 5.0 to 10.0 mm. In Example 1, the fragrance substrate is formed so that the length of the fragrance substrate is 20.0 to 35.0 mm. did.

[0162] In addition, in Examples 1 and 2, a gap of 3.0 mm was set in the axial direction of the cover 10. The aroma base material was then placed in the container to manufacture the aroma cartridge 100. The cover 10 is provided with a lid member 70 for closing the opening at the tip end side of the cover 10 as described in the third embodiment. Thus, the fragrance cartridge 100 was manufactured.

[0163] (Sensory test) The aerosol distribution of the aroma cartridges 100 of Examples 1 and 2 and Comparative Example 1 was measured using a heated tobacco product. The breathability and flavor of the broth were evaluated by a panel of 10 people.

[0164] Of the 10 panelists, 8 panelists were satisfied with the aroma cartridges 100 of Examples 1 and 2. However, the aroma cartridge 100 of Comparative Example 1 has higher breathability and a better smoking experience (a better aroma) than the aroma cartridge 100 of Comparative Example 1. and flavor).

[0165] In addition, 8 out of 10 panelists were unfamiliar with the aroma cartridge 100 of Example 2. However, the aroma cartridge 100 has higher breathability and a better smoking experience (a better aroma) than the aroma cartridge 100 of Example 1. and flavor). [Explanation of symbols]
