Description

[Technical Field]

[0001] The present invention provides a heated aroma-generating group capable of generating an aerosol by heating. The present invention relates to a method for manufacturing a heated aroma-emitting substrate, a heated aroma cartridge, and a heated aroma-emitting substrate. [Background technology]

[0002] The cartridge of a heated smoking device generates an aroma when heated. Aromatic materials such as tobacco plants and non-tobacco plants generate aerosols when heated. and a heated aroma-generating substrate containing an aerosol former (aerosol forming agent). This cartridge is generally heated to over 200°C when used with a heated smoking device. After the heating process of the heated smoking device is completed, the user can remove the The aerosol generated from the

[0003] The diffusion rate of the aroma, which is a volatile component of the aroma source material, is greater in the liquid phase than in the solid phase. A heat-melting substance such as wax is added to the heated aroma-generating base material, and the heated aroma-generating base material is heated. When heated, it promotes the migration of volatile components from within the heated aroma-generating substrate to its surface. It is being carried out.

[0004] Examples of the heated aroma-generating substrate to which wax is added include heated aerosol-generating products. The aerosol-forming substrate comprises tobacco and a melting point of 50°C to 150°C. a homogenized tobacco material containing wax having points, said wax being in contact with said homogenized tobacco material; Patent Document 1 discloses a heated aerosol generating article in which the particles are uniformly distributed within the material. . [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent No. 6433626 Summary of the Invention [Problem to be solved by the invention]

[0006] However, in Patent Document 1, the heated aroma-generating substrate is made of wax from tobacco plants, non- It is formed in a state where it is impregnated with a fragrant material such as tobacco plants. When wax is impregnated into the fiber structure, most of the wax is absorbed into the base material. Therefore, most of the wax moves inwards (towards the fibre structure). In this state, even if the wax melts due to heating, Wax tends to be difficult to leach onto the surface of the heated aroma-generating substrate. The volatile components that migrate from the interior of the heated aroma-generating substrate to its surface are dissolved together with the aroma-generating components. The minutes also decrease.

[0007] Therefore, the temperature rise process from the outside temperature or room temperature to the target heating temperature of the heated smoking device In the early stage, the content of the volatile aromatic components in the aerosol decreases. The aerosol immediately after the heating process using a heated smoking device is found to contain sufficient aromatic components. Therefore, users have a problem in that the scent is hard to detect immediately after the heating process is completed. Ta.

[0008] The present invention has been made in consideration of the above problems, and is directed to a method for preventing a smoking hazard immediately after the completion of the heating process of a heated smoking device. A heated aroma-generating substrate capable of retaining sufficient aroma in the subsequent aerosol. The object of the present invention is to provide a method for manufacturing a heated aroma cartridge and a heated aroma cartridge. . [Means for solving the problem]

[0009] The heated aroma-generating substrate of the present invention comprises: an aroma source material that generates an aroma when heated; An aerosol former that generates an aerosol by being heated, and The aerosol contains a heat-melting substance that melts due to the heat, and contains an aromatic component. In the heated aroma-generating substrate used in the above, the heat-melting substance has a melting point of 50 to 100°C. and the aroma-generating component is dispersed in the heated aroma-generating base material in a sea-island structure. Let's say.

[0010] The aroma-generating substrate to be heated of the present invention is a substrate to be heated in which the heat-fusible substance forms an island structure. In other words, the sea-island structure is composed of components other than the thermally fused material. The melting point of the heat-fusible material is 50 to 100°C. Therefore, the thermally melting substance is in the initial stage of the temperature rise process of the heated aroma-generating substrate. The aromatic components emitted from the aromatic source material dissolve in the molten heat-fusible substance. The thermally meltable substance is dispersed in the heated aroma-generating substrate and is applied to at least the surface of the heated aroma-generating substrate. By forming islands in a sea-island structure, the thermally fused material can be easily mixed with tobacco plants, non-tobacco plants, etc. When melted, it becomes more fluid than when impregnated with the original fragrance material. The amount of dissolved substances that migrates to the surface of the heated aroma-generating substrate together with the aroma components when melted also increases. Therefore, the aroma components of the aerosol increase during the initial heating process of the aroma-emitting substrate. In this stage, it becomes possible to generate aerosols containing many aromatic components. Therefore, the user can enjoy the rich aroma immediately after the heating process is completed. If the melting point of the melting substance is less than 50°C, the heat-fusible substance will melt during hot periods such as summer. If the melting point of the heat-fusible substance exceeds 100°C, the product may become sticky. The heat-melting substance is not fully melted in the early stage of the temperature rise process of the aroma-generating substrate. The aerosol fragrance tends to be lacking immediately after use.

[0011] In the heated aroma-generating substrate of the present invention, the heat-meltable substance has a melting point in the range of 50 to 80°C. It is preferable that the temperature is within the range of 1000 to 2000.

[0012] If the melting point of the heat-melting substance is 50 to 80°C, the aroma-generating substrate will heat up at the beginning of its temperature rise. This makes it easier to melt, and the aroma can be enhanced immediately after the temperature rise process is completed.

[0013] In the heated aroma-generating substrate of the present invention, the heat-meltable substance is selected from the group consisting of beeswax, carnauba wax, and the like. It is preferable that the wax is selected from the group consisting of beeswax, petrolatum, and paraffin wax. It is most preferable.

[0014] The heat-melting substance is selected from beeswax, carnauba wax, vaseline, and paraffin wax. If the aroma-generating substrate is heated, the heat-melting substance will melt further in the early stage of the temperature rise process. This makes it easier to dissolve, and the aroma can be enhanced immediately after the temperature rise process is completed. If the quality is beeswax, the aromatic components contained in the beeswax itself will evaporate, resulting in a more pleasant fragrance. You can taste it.

[0015] In the heated aroma-generating substrate of the present invention, the thermally fusible substance may contain an aromatic agent. preferable.

[0016] In the heated aroma-generating substrate of the present invention, a sorbent capable of retaining the aroma is It is preferred that it contains

[0017] By including a sorbent capable of retaining the fragrance, the heated aroma-generating substrate can be heated. Even at the end of the period when smoking or aerosol inhalation is possible, The concentration of the aromatic component of the fragrance contained in the aerosol can be maintained at a high level. Immediately after the end of the heating process, the heat-melting substance melts easily in the early stages of the heating process. The fragrance of the fragrance can be enhanced, and the sorbent can retain a high concentration of the fragrance components of the fragrance. Therefore, the user can enjoy the aroma throughout the entire smoking or aerosol inhalation period. You can enjoy a wide variety of flavors.

[0018] When the heat-melting substance contains an aromatic substance, the aromatic substance is heated at an early stage of the heating process of the aroma-emitting substrate. The heat-melting substance melts, and the fragrance evaporates and becomes more likely to flow out with the aerosol. This can further enhance the aroma immediately after the temperature rise process is completed.

[0019] The aroma-generating substrate to be heated according to the present invention contains 2 to 20% by mass of the heat-meltable substance. It is preferable that:

[0020] The content of the heat-fusible substance is 2 to 20 mass %, so that the heat-fusible substance is melted. This can facilitate the generation of aromatic components.

[0021] In the heated aroma-generating substrate of the present invention, the aroma source material is derived from a non-tobacco plant. It is preferable that

[0022] If the aroma source material is derived from a non-tobacco plant, it does not contain nicotine and is therefore safe for users. The consumer tends to seek a stronger aroma and a more stimulating sensation than when tobacco plants are used as the aroma source. As described above, the heated aroma-generating substrate of the present invention generates a good aroma by using a thermally melted substance. This allows us to meet user expectations.

[0023] The heated aroma cartridge of the present invention is attached to an inhalation device having an electric heating means, and A heated aroma cartridge that generates an aerosol containing aroma components when heated. The device has a cylindrical cover and a heating element housed at one end of the cover. a heated aroma-generating substrate that generates an aerosol containing an aroma component by heating the heated aroma-generating substrate; and a filter housed on the side of the heated aroma-generating substrate. The aroma-generating heated base material described above is used.

[0024] According to the heated aroma cartridge of the present invention, by using the heated aroma-generating substrate, The user attaches the heated aroma cartridge to an inhalation device, heats it, and inhales the aerosol. From the very beginning, you can smell the rich aroma.

[0025] The method for producing a heated aroma-generating substrate of the present invention is to produce an aroma-generating substrate that generates an aroma by heating. A fragrance source material, an aerosol former that generates an aerosol by heating, and a heated The ingredients containing the heat-melting substance are mixed and molded to generate the aroma when heated. A method for producing a substrate, comprising the steps of: The powder is added to the raw material, and the raw material is melted by the heat-fusible substance. The method is characterized in that the mixture is mixed and molded at a temperature below the melting point.

[0026] According to the method for producing a heated aroma-generating base material of the present invention, the thermally fusible substance remains in a sea-island structure. Therefore, the aroma-generating base material to be heated is manufactured so that the aroma component is dissolved in the heat-melting material. moves to the surface of the heated aroma-generating substrate and becomes more likely to volatilize along with the aerosol former. Therefore, in the early stage of the temperature rise process of the heated aroma-generating substrate, many of the aroma components are released. It is possible to generate an aerosol containing the vapor. You can enjoy the rich aroma immediately after the heating process is complete.

[0027] In the method for producing a heated aroma-emitting substrate of the present invention, the thermally fusible substance is made to contain an aromatic agent. It is preferable to mix the raw materials and add the powder to the raw materials.

[0028] By incorporating an aromatic substance into the heat-melting substance, the heated aromatic cartridge can be inserted into the inhaler. When the device is attached and heated, the heat-melting substance melts and the fragrance evaporates in the early stages of inhalation. As the fragrance flows out, you can feel a richer aroma from the early stages of inhalation. do. [Effects of the Invention]

[0029] According to the heated aroma-generating substrate of the present invention, in the early stage of the temperature rise process of the heated aroma-generating substrate, Therefore, it is possible to generate an aerosol containing many aromatic components. Users can enjoy the rich aroma immediately after the heating process of the heated smoking device is completed. .

[0030] According to the heated aroma cartridge of the present invention, since it contains the heated aroma-generating substrate of the present invention, The user can enjoy a rich aroma immediately after the heating process using the heated smoking device is completed.

[0031] According to the method for producing a heated aroma cartridge of the present invention, the raw material is heated to a temperature lower than the melting point of the heat-fusible substance. By mixing and molding at a temperature of 100°C, the heat-melting material remains in an island structure. By this, the heat-melting substance in which the aromatic component is dissolved moves to the surface of the heated aroma-generating substrate, It becomes more volatile along with the aerosol former, so immediately after the heating process using the heated smoking device is completed, You can enjoy the rich aroma later.

[0066] (thermally melting substances) 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 there is any heat, the heat-melting substance may melt during hot weather such as summer, causing stickiness. In addition, if the melting point of the heat-fusible substance exceeds 100°C, the aroma-emitting substrate will The heat-fusible substance is not fully melted in the early stages of the smoking process, and the The aerosol tends to lack fragrance.

[0067] 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 average particle size in the present invention can be measured by a distribution measuring device. It means the diameter of Anne.

[0069] If the average particle size of the heat-melting material is too large, the total surface area will be small, making it difficult to contact the heat source. As a result, the heat-melting material is not melted sufficiently, and the The concentration of the fragrance component in the aerosol tends to decrease.

[0070] If the outer diameter of the thermally fused substance is too small, the thermally fused substance will be dispersed in the heated aroma-generating substrate 20 (described later). As a result, it becomes difficult to form a dispersed sea-island structure. Since the aroma-generating substrate 20 is present as a crystalline substance, the melting rate upon contact with a heat source is reduced. The concentration of the aromatic components in the aerosol immediately after the heating process is completed tends to decrease. There is a direction.

In particular, metallocene catalyst polyolefin waxes are more preferred because they have a narrow molecular weight distribution. For example, Mitsui Chemicals' Excelex (registered trademark) is a metallocene catalyst PE wax. The "Heat Melting Point" (HM) has a narrow molecular weight distribution and composition distribution, and therefore has a melting point of 89 to 128°C. It has a low melt viscosity when dissolved, making it an excellent polyolefin wax.

[0089] Such higher fatty acids and higher aliphatic alcohols are each formed by cleaving a terminal end of a straight-chain hydrocarbon. Carboxyl and hydroxyl groups are bonded to the polymer, and there is no molecular weight distribution or The fabric is extremely narrow. Therefore, like paraffin wax, it has a low melt viscosity when heated and a melting point of The temperature range is also narrow, which promotes deformation and flow of the aroma-emitting substrate 20 when heated. The effect is great.

[0090] As for polyoxyalkylene glycol, polyethylene glycol has an average molecular weight of 6 Those having a molecular weight of 00 to 11,000 have a low melting point and a low melt viscosity when thermally melted, and are therefore preferred. It is a polyethylene glycol-polypropylene glycol block polymer, The glycol unit is 40 to 80 wt% and the average molecular weight is 3,000 to 13,000. 00. Polyoxyalkylene glycols that satisfy this requirement are non-isopropyl It is also used as an anionic surfactant, but it has a narrow molecular weight distribution and a melting point temperature range. Because it is narrow, it has excellent fluidity when melted by heat.

[0091] Polyoxyethylene alkyl ethers include polyoxyethylene-monomethyl ethers. The average molecular weight of the ester is preferably 1,000 to 4,000. It is used as an activator, but because the molecular weight distribution is narrow and the melting point temperature range is narrow, It has excellent fluidity when melted by heat.

[0092] Polyoxyethylene alkylamines include polyoxyethylene-stearylamine Preferably, Nymeen (registered trademark) S202 manufactured by NOF Corporation is used. It is used as an ionic surfactant, but it is a linear hydrocarbon unit with 18 carbon atoms. It has a narrow molecular weight distribution and a narrow melting point temperature range, so it has good fluidity when melted. Excellent.

[0095] (Air freshener) The fragrance can be added together with the aerosol former, but it is preferable to add it to the heat-melting substance in advance. It is more preferable that the fragrance is selected from the group consisting of a refreshing agent and nicotine. At least one of the above can be used.

[0096] Examples of the cooling agent include menthol, menthol derivatives, menthone, and menthone derivatives. Menthanecarboxylic acid amide, 2,3-dimethyl-2-(2-propyl)-butyric acid derivative , Menthane, Menthane derivatives, L-Carvone, Xylitol, Eucalyptus essential oil, Peppermint oil, Spearmint essential oil, spilanthol, etc. can be used.

The oil content is preferably 3 to 25% by mass, and more preferably 5 to 20% by mass. The content of the agent is based on 100% by mass of the total amount of the fragrance source material, aerosol former, and thermal melting substance. If the content is less than 3% by mass, the aromatic components generated from the aromatic agent are sufficiently contained in the aerosol. In addition, the amount of fragrance contained in the air freshener is often If the amount exceeds 25% by mass relative to 100% by mass of the total amount of the molten material and the heat-melting substance, the aromatic group that is heated may be The strength of the material 20 tends to decrease.

[0098] (molding agent) The molding agent is used to reinforce the heated aroma-emitting substrate 20. Examples of the molding agent include For example, cellulose fiber, microcrystalline cellulose, etc. can be 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 having such a fiber diameter and fiber length, the aroma-generating group upon heating can be easily obtained. This makes it possible to enhance the effect of binding the constituent components of the material 20 together.

[0100] The microcrystalline cellulose preferably has an average particle size of 70 to 120 μm. When the average particle size of the crystalline cellulose is less than 70 μm, the shrinkage of the aroma-generating substrate 20 to be heated is suppressed. Furthermore, it tends to be difficult to prevent adhesion between the heated aroma-emitting substrate 20 and the molding machine. When the average particle size of the microcrystalline cellulose exceeds 120 μm, the aroma-generating substrate 20 The average particle size of microcrystalline cellulose is measured by a laser diffraction particle size analyzer. The average particle size in the present invention can be measured by a fabric measuring device. This means:

[0101] The mass average molecular weight (Mw) of microcrystalline cellulose is 20,000 to 60,000. It is preferable that the mass average molecular weight (Mw) of the microcrystalline cellulose is less than 20,000. If there are any microcrystals, the effect of suppressing the shrinkage of the aroma-generating substrate 20 to be heated tends to be poor. When the mass average molecular weight (Mw) of the cellulose exceeds 60,000, the aroma-generating base material to be heated 20 tends to break easily.

[0102] The molding agent is, relative to 100% by mass of the total amount of the fragrance source material, aerosol former, and thermally melting substance, The content is preferably 2 to 25% by mass, and more preferably 3 to 20% by mass. By including the filler in the heated aroma-generating substrate 20 in this manner, the above-mentioned functions can be achieved. At the same time, the forming agent is an obstacle to the generation of volatiles from the fragrance source material and the aerosol former. This can prevent the following.

[0103] (binder) The binder is a mixture of the aroma source material, aerosol former, and heat-melting material that constitute the heated aroma-generating base material. It is used to bind raw materials such as sugars. Examples of binders include polysaccharide polymers. , cellulose-based polymers, etc. can be used.

Gum and locust bean gum are more preferred.

[0105] Examples of cellulose polymers include carboxymethyl cellulose (CMC), carboxyethyl cellulose, hydroxymethyl cellulose, hydroxyethyl cellulose, Hydroxypropyl cellulose, sodium salt of CMC, potassium salt of CMC, Calcium salt, sodium salt of carboxyethyl cellulose, carboxyethyl cellulose Examples of the salt include potassium salt of carboxyethyl cellulose and calcium salt of carboxyethyl cellulose. From the viewpoint of the strength and moldability of the heated aroma-emitting substrate 20, the cellulose-based polymer is Sodium CMC, Potassium CMC, Sodium Carboxyethylcellulose The salt, potassium salt of carboxyethyl cellulose, is preferred.

[0106] As the binder, it is preferable to use a polysaccharide polymer and a cellulose polymer in combination. In this case, examples of polysaccharide polymers include glucomannan, guar gum, and tamarind gum. It is preferable to use locust bean gum or cellulose gum. , Sodium salt of CMC, Potassium salt of CMC, Sodium carboxyethyl cellulose It is preferable to use the potassium salt of carboxyethyl cellulose. By using a polysaccharide polymer and a cellulose polymer in combination, the heated aroma-generating substrate 2 This can improve the strength and moldability of the product.

[0107] The binder accounts for 100% by mass of the total amount of the fragrance source material, aerosol former, and heat-melting substance. The content is preferably 5 to 30 mass %, and more preferably 8 to 28 mass %. It is more preferable that the binder is contained in the heated aroma-generating substrate 20 in such a content. This improves the strength and moldability of the aroma-generating substrate 20 to be heated, This can avoid adverse effects on the generation of volatile substances from the fragrance source material and the aerosol former.

[0108] The aroma-generating substrate 20 to be heated according to the present invention contains both a binder and a molding agent. In this case, the blending ratio of the binder to the molding agent is preferably 1:1 to 1:2 by mass. A value of 5 is preferable in terms of cohesion.

[0109] (sorbent) If the fragrance is not contained in the thermally meltable substance, the fragrance may be heated by the temperature of the heated fragrance-emitting substrate 20. Prevents the aerosol former and fragrance source material from evaporating before reaching the optimum temperature for evaporation. As described above, the sorbent is used to absorb the aroma of the heated aroma-generating material 20. Fragrances can be retained.

[0110] The sorbent may be of various types depending on the manner in which a compound such as an aromatic agent is retained in the aroma-generating substrate 20. For example, a base material that generates a fragrance by incorporating the compound can be used. Sorbents that retain 20 can be used, such as cyclodex. Thorin can be used.

[0111] Cyclodextrins are encapsulated with chemicals containing hydroxyl and carboxyl groups of various sizes. It is known that α-, β-, and γ-cyclodextrins form complexes with In particular, β-cyclodextrin forms an inclusion compound with menthol. and is an ideal sorbent for menthol.

[0112] When cyclodextrin is used as the sorbent, the sorbent is an aromatic source material, an aerosol former, and the content of the heat-melting substance is preferably 0.1 to 1.2 mass% relative to 100 mass% of the total amount of the heat-melting substance. It is more preferable that the content is 0.2 to 1.0 mass %.

[0113] In addition, a sorbent is used to adsorb the compound and retain it on the fragrance-emitting substrate 20. For example, when the compound is menthol, the menthol can be substituted with phenol. Therefore, as a sorbent, it is possible to adsorb phenolic hydroxyl groups. For example, a hydrophilic cross-linked polymer such as cross-linked polyvinylpyrrolidone (PVP) can be used. This can be done.

[0114] Also, for example, when the compound is nicotine, nicotine is a five-membered heterocycle containing nitrogen. Therefore, as a sorbent, it is compatible with five-membered heterocyclic compounds containing nitrogen. Crosslinked PVP may be used, which is believed to form the effect.

[0115] When cross-linked PVP is used as the sorbent, the sorbent is used as the fragrance source, aerosol former, and heat-melting agent. It is preferable that the content of the dissolving material is 4 to 25 mass%, and 5 to 20 mass%. It is more preferable that the content is 100%. The sorbent contains both cross-linked PVP and cyclodextrin. Preferred.

[0116] (preservative) To preserve the heated aroma-emitting cartridge for a long period of time, a preservative may be used. As the agent, for example, potassium sorbate and / or sodium benzoate can be used. The preservative is contained in the fragrance source material, aerosol former, and heat-melting substance in a total amount of 100 mass. %, it is preferable that the content is 0.005 to 0.04 mass %.

[0117] (Surface aspect of the heated aroma-generating substrate 20) FIG. 4 is a schematic diagram showing the state of the heat-melting substance HS contained in the heated aroma-generating substrate 20. As shown in FIG. 4, the heat-melting substance HS forms an island structure in the heated aroma-generating substrate 20. It is distributed in a way that is easy to understand.

[0118] The sea-island structure is composed of components other than the thermally fused substance HS, and the thermally fused substance HS In other words, the heat-melting substance HS is dispersed in the heated aroma-generating substrate 20. It exists as a mass that defines a certain area in the

[0119] The sea-island structure is formed on the surface of the heated aroma-generating substrate 20 and also inside the same. Therefore, the surface of the heated aroma-generating substrate 20 has a sea-island structure as shown in FIG. The cut surface of the aroma-generating substrate 20 to be heated cut at any position is shown in FIG. The structure has an island-in-a-sea structure.

[0120] In addition, the melting point of the heat-melting substance HB is in the range of 50 to 100°C as described above. Therefore, the heat-melting substance HS melts in the early stage of the temperature rise process of the heated aroma-emitting substrate 20. The aromatic components emitted from the aromatic source material dissolve in the molten heat-fusible substance HB.

[0121] The heat-melting substance HS forms islands in a sea-island structure within the heated aroma-generating substrate 20, When the thermal aroma generating base material is heated and the thermal melting substance HS melts, the aroma generated from the aroma source material The ingredients and the fragrance ingredients of the fragrance dissolve in the molten heat-melting substance HS and become one with the heat-melting substance HS. It becomes easier to flow together.

[0122] The melted heat-melting substance HS flows within the heated aroma-emitting substrate 20 and forms an aerosol. When the aerosol former comes into contact with the fragrance component, the fragrance component is contained in the aerosol former and volatilizes as an aerosol. Therefore, in the early stage of the temperature rise process of the heated aroma-generating substrate 20, Therefore, the user can easily use the heated smoking device. You can enjoy the rich aroma immediately after the heating process is complete.

[0123] Next, a method for manufacturing the heated aroma-generating substrate 20 will be described. 5 shows one embodiment of a manufacturing process for the generating substrate 20. As shown in FIG. A raw material (A) mixed with a molten substance, a raw material (B) which is cellulose fiber as a binder, and Aerosol formers, fragrances, molding agents, binders (excluding cellulose fibers), sorbents, preservatives The mixing step is performed by mixing the raw material (C) prepared by mixing the agent and pure water. The mixing step is carried out below the melting point of the substance. The mixing step can be carried out, for example, using a known mixer. Cut.

[0124] The raw material (A) is a mixture of dried, insecticided and crushed fragrance material and crushed heat-melting material. The mixture is compressed and sheared to mix, and the compressed and sheared mixture is cooled to below 0°C and then crushed. This can be obtained.

[0125] Raw material (B) is made by crushing compressed cellulose fibers and boiling the crushed cellulose fibers. After that, the raw material (B) is dehydrated and dried and then crushed. It is a raw material used in

[0126] Raw material (C) is an aerosol former that is an essential ingredient, and also contains fragrances, molding agents (cellulose fibers), Any of the following may be used: binders, sorbents, preservatives, and pure water. .

[0127] By carrying out the mixing step in this manner, the aroma source material is mixed into the heated aroma-generating substrate 20. The combined powders of the heat-fusible material can form a dispersed islands-in-a-sea structure.

[0128] Next, the mixture obtained in the mixing step is compressed and sheared to form it into a sheet. Compression and shear processing can be performed using, for example, 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.

[0129] The sheet obtained in this way has a porous structure containing air inside. As a result, it is possible to obtain a heated aroma-emitting substrate 20 with low density. The rolls of the three-roll mill have extremely flat surfaces, which allows the sheet surface to be formed evenly. .

[0130] That is, the aroma-generating substrate 20 to be heated contains air inside during compression and shear processing. It has a porous structure, making it low density, and its surface is smooth and even. It becomes something.

[0131] The mixture formed into a sheet by compression and shear processing is cut into a desired shape and size. The sheet-like mixture is then cut into strips, for example.

[0132] The mixture cut into a predetermined shape and size is placed on the cover 10, and the filter 30 and the support The cover 10 is then rolled up to encase the components 40. The heated aroma cartridge 100 is manufactured by fixing the ends of the cartridge 10 together. .

[0133] In this way, the mixing process, compression / shearing process, and cutting process are carried out below the melting point of the heat-melting substance. This prevents the melting of the heat-melting substance from spreading over the entire heated aroma-emitting substrate 20. This prevents the heat-melting substance from being melted, and the sea-island structure of the heat-melting substance in the aroma-generating substrate 20 to be heated can be maintained. do.

[0134] A sea-island structure in which powder of a heat-melting substance mixed with an aroma source material is dispersed in the heated aroma-generating substrate 20. When the heat-melting substance is formed, the heat-melting substance is dispersed and arranged in the aroma-emitting substrate 20 to be heated in the form of islands. This becomes the case.

[0135] The heat-melting substance is dispersed in the heated aroma-generating substrate 20 in an island-like manner, rather than being impregnated in the aroma source material. The dispersed arrangement of the fragrance material makes it easier to flow when melted, and the fragrance generated from the fragrance material is In addition, when the flowing thermally fused substance comes into contact with the aerosol former, When the fragrance comes into contact with the aerosol former, it becomes an aerosol and evaporates easily. This can be done.

[0136] As a result, the aromatic components of the aromatic source material can be efficiently volatilized. The laser emits the aroma from the heated aroma cartridge 100 immediately after the end of the heating process of the heated smoking device. When the aerosol is inhaled, the aroma can be enjoyed more fully.

[0137] The aromatic substance may be added to the raw material (A). 6 shows another embodiment of the manufacturing process of 20. As shown in FIG. When adding, for example, the powdered heat-melting substance and the fragrance are heated and mixed at a temperature above the melting point of the heat-melting substance. After mixing and cooling, the mixture is crushed to a predetermined size, and the crushed material is mixed with the powdered aroma source material. It is recommended to compress and shear the mixture.

[0138] The manner in which the aromatic agent is added to the raw material (A) is not limited to the above. For example, one of the aromatic agents may be added to the raw material (A). Part or all of the raw material (A) may be added during compression and shear mixing. By adding an aromatic agent to the raw material (A), the user can enjoy the aroma emitted from the aromatic agent. The ingredients can be fully enjoyed immediately after the heating process is complete.

[0139] As described above, according to the aroma-generating substrate 20 to be heated of the present invention, In the early stage of the heating process, aerosols containing many aromatic components can be generated. It becomes possible.

[0140] According to the heated aroma cartridge 100 of the present invention, since it includes the heated aroma-emitting substrate 20, The user can enjoy a rich aroma immediately after the heating process of the heated smoking device is completed.

[0141] According to the method for manufacturing the heated aroma cartridge 100 of the present invention, the thermally fusible substance is formed in an island-sea structure. By leaving the mixture in a state, the heat-melting material becomes more fluid, and the generated aromatic compounds The components dissolve in the heat-melting substance, making it easier for the fragrance components to flow out with the aerosol. do.

[0154] In addition, a heated aroma cartridge was prepared using raw materials (A) to (C) in the manner shown in FIG. Specifically, a mixing step was carried out in which raw materials (A) to (C) were mixed in a kneader.

[0155] Next, a compression and shearing process was carried out using three rolls to form the mixture into a sheet. In the compression and shear process, the material was formed into a sheet with a thickness of 0.28±0.02 mm. The compression and shearing process was carried out below the melting point of beeswax.
