Description

Technical Field

[0001] The present invention relates to a heatable aroma-generating base material provided in a heatable aroma cartridge suitable for a heated smoking device, a heatable aroma cartridge including the heatable aroma-generating base material, and a method for producing the heatable aroma-generating base material.

[0002] In particular, the heatable aroma-generating base material of the present invention is produced by mixing at least an aroma source material, an aerosol former, and a binder, and then subjecting the mixture to a molding process in which a compressive shear force is applied, wherein the aroma source material, the aerosol former, and the binder are uniformly dispersed and bound together. As a result, when the heatable aroma cartridge including the heatable aroma source formed of the heatable aroma-generating base material of the present invention is attached to or detached from a heated smoking device, problems such as deformation, falling-off, and dropping of the heatable aroma-generating base material do not occur; during smoking, the aroma volatilized from the heated aroma source material can be fully enjoyed; and in the production of the heatable aroma-generating base material, since the aroma source material, the aerosol former, and the binder are uniformly dispersed and bound together, and the base material has the toughness and strength required for molding processing, stable production can be achieved.

[0003] Furthermore, the heatable aroma-generating base material of the present invention is characterized in that when a cooling agent such as menthol or xylitol is added as an aromatic agent, dissipation of the cooling agent over time is suppressed, and even after long-term storage of the heatable aroma cartridge including the heatable aroma source containing the base material, the effect that the aroma of the heatable aroma-generating base material can be fully enjoyed when the heatable aroma cartridge is attached to a heated smoking device for smoking is achieved.

[0004] Furthermore, the heated fragrance generating substrate of the present invention is characterized by minimal dimensional change due to drying. Even after smoking with a heated fragrance cartridge equipped with a heated fragrance generating source made of the substrate, the heated fragrance generating substrate does not detach or fall from the heated fragrance cartridge. Even after long-term storage, the heated fragrance generating substrate does not detach or fall from the heated fragrance cartridge, resulting in excellent handling and preventing contamination of the heat source of the heated smoking device.

[0005] Incidentally, the above-mentioned "heated aroma generating substrate" has traditionally been called an "aerosol forming substrate." However, since heating causes the aerosol former to form an aerosol, along with the fragrance components of the aroma source material and fragrance agent, and the smoke of the aerosol and the fragrance of the aroma source material and fragrance agent are enjoyed by smoking, in this invention it will be called a "heated aroma generating substrate." Based on this, an "aerosol forming body" filled with the aerosol forming substrate and an "electronic cigarette cartridge" equipped with an aerosol forming body will be called a "heated aroma generating source" and a "heated aroma cartridge," respectively. However, the term "heated aroma cartridge" is not limited to this and may also be called a "smoking cartridge" or an "electronic cigarette compatible cartridge."

[0006] Furthermore, the sources of the fragrance are not limited; tobacco plants of the Solanaceae family, related plants, and non-tobacco plants that do not contain tobacco components can be used. "Fragrance" means "pleasant scent," and refers to the scent that emanates from the material itself (fragrance), the scent that dissipates into the air when heated (aroma), and the scent that lingers in the mouth when inhaled (flavor), which can be perceived during smoking. "Smoking" generally refers to smoking cigarettes or cigars, but here it simply means "enjoying the smoke," "savoring the fragrance," or "enjoying the smoke and fragrance." Therefore, "smoke" here does not refer to something produced by combustion, but rather to something that "looks like smoke" or "smoke-like," such as droplets dispersed in the air as an aerosol. [Background technology]

[0007] In recent years, smoking bans have become widespread in places where people gather, such as workplaces and restaurants. In response, tobacco manufacturers have developed a method of smoking a heated aroma cartridge that, when placed inside the chamber of a heated smoking device, generates an aerosol through heat transmitted from an electronically controlled blade-type heat source (Patent Document 1). This heated aroma cartridge is equipped with a heated aroma source formed using a heated aroma generating base material containing an aerosol former, an aroma source material including tobacco plants of the Solanaceae family, and a binder. When the heated aroma generating base material is heated, volatile substances are generated. The volatile substances from the aerosol former are cooled and become smoke, and the volatile substances from the aroma source material become aroma, allowing users to enjoy a smoking experience similar to that of conventional cigarettes. With this heated smoking method, the inhalation of harmful components generated by the thermal decomposition and combustion of conventional cigarettes is reduced, resulting in a sharp decline in the number of smokers of conventional cigarettes, while the number of smokers of heated tobacco products is rapidly increasing. For this reason, there is active technological development to further enhance the enjoyment of heated smoking (for example, Patent Documents 1-12).

[0008] The mechanism of such heated smoking varies depending on the form of the heated smoking device and the heated fragrance cartridge, but a typical example is shown below. A heated fragrance cartridge has a heated fragrance source filled with a heated fragrance generating base material at one end and a mouthpiece at the other end. When the heated fragrance source is attached to the heat source of the heated smoking device so as to be in contact with the heat source and heated, volatile substances such as aerosol former and fragrance source material are released from the heated fragrance source. These volatile substances are drawn in with the air towards the mouthpiece at the other end by the smoker's inhalation. In this volatile substance transport process, the volatile substances of the aerosol former cool and condense to form an aerosol resembling smoke, while the other volatile substances provide fragrance to the smoker's mouth and nose, resulting in the enjoyment of smoking. Therefore, in the case of heated tobacco products, smoking can be performed at a temperature of approximately 200-350°C, which is the temperature at which thermal decomposition of tobacco leaves begins, allowing the aerosol formers such as glycerin and propylene glycol contained in the heated aroma-generating substrate to volatilize. This not only prevents the generation of harmful substances due to combustion but also reduces the generation of harmful substances due to thermal decomposition.

[0009] As can be seen from this mechanism, in heated smoking devices, the heat source and its control method play an extremely important role, greatly influencing the generation of smoke and aroma. As a result of many years of development, blade-type heat sources using heaters have been widely used to this day (for example, Patent Documents 1-5). In contrast, recently, omnidirectional heat sources using electromagnetic induction heating have been put into practical use. It is thought that the aim is to enhance the generation of volatile substances and provide a deeper flavor because the heating speed is fast and the contact area with the heated aroma-generating substrate is large (Non-Patent Document 1).

[0010] Meanwhile, various efforts have also been made to develop technologies related to heated aroma-generating substrates, which are the source of smoke and aroma (for example, Patent Documents 6-12). These substrates require aerosol formers with boiling points of 180-300°C, such as glycerin and propylene glycol, as essential components. These are mixed with aroma-generating materials such as tobacco plants, non-tobacco plants, and fragrances to form a homogeneous viscoelastic body. For this reason, linear, side-chain, and branched polysaccharide polymers such as cellulose, guar gum, and gum arabic are used as binders. In addition, wetting agents and the like are added to uniformly disperse these materials.

[0011] Conventionally, heating-to-generate aroma-generating substrates have been manufactured by either casting them in a papermaking process that involves dispersing an aerosol former, aroma source material, binder, wetting agent, etc., in water to produce an aqueous slurry, followed by a papermaking process that includes compression and heat drying, or by extruding a viscoelastic body made by adding an appropriate amount of lower alcohol or water to a mixture of aerosol former, aroma source material, binder, wetting agent, etc. (Patent Documents 6 and 7). However, these methods cannot produce a viscoelastic body in which the components constituting the heating-to-generate aroma-generating substrate are homogenized, resulting in insufficient mechanical strength of the molded product. This often leads to the problem of the heating-to-generate aroma-generating substrate breaking during the processing stage into a heating-to-generate aroma-generating source. Furthermore, heating-to-generate aroma-generating substrates that are not homogenized suffer from insufficient packing of the aroma source and binder, resulting in severe shrinkage when heated and dried. This can lead to problems such as breaking during the heating and drying stage when processing into a heating-to-generate aroma-generating source, or the heating-to-generate aroma-generating substrate falling off or dropping after smoking.

[0012] Regarding the detachment, falling, cracking, or damage of the heated fragrance-generating substrate after smoking, the effectiveness of inorganic binders has been disclosed (Patent Document 8). This solution is based on the fact that the combustion of the heated fragrance-generating material is suppressed by improving the heat resistance to the heat source, rather than by improving heterogeneity, and furthermore, because the relative proportion of the fragrance source material and aerosol former in the heated fragrance-generating substrate decreases, there is a problem that it leads to a decrease in the amount of fragrance and smoke produced.

[0013] Furthermore, heterogeneity arising from the chemical properties of the components constituting the heated aroma-generating substrate also leads to a decrease in the amount of aroma and smoke produced. In particular, the low chemical affinity between the aroma source material and the aerosol former means that the aroma source material cannot dissolve in the aerosol former and is forced to disperse, resulting in the irregular presence of aerosol former of various volumes and clumps of aroma source material of various sizes. Therefore, even when heated by a heat source, the heated aroma-generating substrate is in such a heterogeneous state that the heat is not evenly transferred to the aroma source material and the aerosol former. As a result, the aromatic components of the aroma source material are not sufficiently volatilized, leading to an unsatisfactory smoking experience. Similarly, the aerosol former is not sufficiently volatilized, and it is not possible to produce enough smoke to please the smoker. To address these problems, a solution has been proposed in which wax is added to increase the fluidity of the volatile components of the aroma source material and aerosol former, thereby promoting the release of volatile substances from the heated aroma-generating substrate (Patent Documents 9 and 10). However, because wax is hydrophobic, it is difficult to produce a homogenized heating-to-aroma-generating substrate, especially using the casting method, and significant improvement cannot be expected. In addition, the wax causes a problem with the mechanical strength of the heating-to-aroma-generating substrate, making it brittle.

[0014] Furthermore, in heated tobacco products, as with combustible tobacco products, cooling agents such as menthol and xylitol are sometimes added as fragrances to provide a refreshing sensation when smoked. In addition, flavorings such as fruit and nut flavors may be added. In such cases, in the heating and drying process for manufacturing the heated aroma-generating substrate by the casting method described above, there is a problem of the cooling agents and flavorings dissipating. Moreover, the hydrophilic-hydrophobic balance of the components constituting the heated aroma-generating substrate, including the cooling agents and flavorings, and the presence of a large amount of components that do not dissolve in the aerosol former, resulting in a lack of homogenization, also leads to the cooling agents and flavorings dissipating over time. To address these problems, inclusion of cooling agents and flavorings with various cyclodextrins and encapsulation of cooling agents and flavorings with wax have been disclosed as means of solving these problems (Patent Documents 11 and 12). To form the former inclusion compound, it is necessary to find a suitable combination of cooling agent and flavoring with cyclodextrin, select a suitable solvent, homogenize the cooling agent and flavoring with cyclodextrin using a homogenizer, and then spray dry, freeze dry, or vacuum dry. Therefore, the applicable cooling agents and flavorings are limited, and the manufacturing process requires considerable effort.

[0015] As mentioned above, due to the manufacturing methods of casting and extrusion molding, as well as the chemical properties of the constituent components, the heated aroma-generating substrate suffers from a problem of heterogeneity. This problem may be solvable by adopting a compression and shearing process as a manufacturing method. For example, a method using a three-roll mill that can uniformly knead and disperse a high-viscosity paste through compression by pressing it between narrow rolls and shearing due to the difference in roll speeds, and that can also form it into a sheet, is conceivable. However, in this case, the sheet used as the heated aroma-generating substrate suffers from insufficient strength and high tackiness, leading to cohesive failure and adhesion to the metal rolls, making it difficult to form into a sheet.

[0016] As described above, in order to enjoy smoking a heat-not-burn tobacco product, that is, to enjoy smoking by mounting a heated aromatic cartridge to a heat-not-burn smoking device, it is necessary to further solve various problems caused by the composition of the heated aroma-generating substrate that constitutes the heated aroma-generating source of the heated aromatic cartridge, along with improvements to the heat-not-burn smoking device.

[0019] An object of the present invention is to provide a heatable aroma-generating base material provided in a heatable aroma cartridge suitable for a heated smoking device, the heatable aroma-generating base material comprising at least an aroma source material, an aerosol former and a binder, being manufactured through a molding step in which compression shear force is applied after these components are mixed, and being characterized in that the aroma source material, the aerosol former and the binder are uniformly dispersed and bound.

[0020] As a result, problems such as deformation of the heatable aroma-generating source, falling-off and dropping of the heatable aroma-generating base material when attaching and detaching the heatable aroma cartridge having the heatable aroma source constituted by the heatable aroma-generating base material of the present invention to and from a heated smoking device are solved, and the present invention can provide a heatable aroma-generating base material that imparts the toughness and strength required for the molding process and allows a user to fully enjoy the aroma volatilized from the heated aroma source material.

[0021] Furthermore, the present invention aims to provide a heated aroma generating substrate in which, when a cooling agent such as menthol or xylitol is added as an aroma, the dissipation of the aroma and cooling agent over time is suppressed, and even after a heated aroma cartridge equipped with a heated aroma generating source containing it has been stored for a long period of time, the aroma of the heated aroma generating substrate can be fully enjoyed when it is attached to a heated smoking device and smoked.

[0022] Furthermore, the present invention aims to provide a heated aroma generating substrate that exhibits minimal dimensional changes due to drying, prevents detachment or falling from the heated aroma cartridge even after smoking with a heated aroma cartridge containing the heated aroma generating source attached to a heated smoking device, and prevents detachment or falling from the heated aroma cartridge even after long-term storage, offers excellent handling, and prevents contamination of the heat source of the heated smoking device.

[0023] Thus, the main problems that the present invention aims to solve are homogeneous mixing and dispersion of materials with different properties, such as fragrance source material, aerosol former, binder, and fragrance, which are present in conventional heated fragrance generating substrates, as well as easy prevention of the dissipation of fragrance over time and prevention of shrinkage of shape over time and due to heat. [Means for solving the problem]

[0024] The inventors investigated various materials in addition to the fragrance source material, aerosol former, binder, and fragrance that constitute the heated fragrance generating substrate. As a result, they discovered that the above problems could be solved by selecting two types of binders, determining an appropriate method for their blending, and adding cross-linked polyvinylpyrrolidone (PVP) and microcrystalline cellulose, leading to the completion of the present invention.

[0025] In other words, the present invention relates to a heated aroma-generating substrate containing at least an aroma source material, an aerosol former, and a binder, wherein the binder contains a first binder and a second binder, the first binder being at least one cellulosic polysaccharide selected from the group consisting of methylcellulose, ethylcellulose, carboxymethylcellulose, carboxyethylcellulose, hydroxymethylcellulose, hydroxyethylcellulose, and hydroxypropylcellulose, and their sodium salts, potassium salts, and calcium salts, and the second binder being at least one polysaccharide other than a cellulosic polysaccharide selected from the group consisting of glucomannan, guar gum, pectin, carrageenan, locust bean gum, and agar.

[0026] By using the first and second binders in combination, the fragrance source material and aerosol former constituting the heated fragrance generating substrate are homogeneously mixed and dispersed, and their bonding strength is enhanced, resulting in a heated fragrance generating substrate with the toughness and strength required for molding. As a result, even immediately after manufacturing a heated fragrance cartridge equipped with this heated fragrance generating substrate, and even after long-term storage, it can be attached to and detached from a heated smoking device without the heated fragrance generating substrate falling off, dropping, or deforming. Furthermore, sufficient fragrance from the fragrance source material and smoke generation from the aerosol former are produced during smoking. Moreover, because the fragrance source material and aerosol former are homogeneously mixed and dispersed via the binder, it becomes possible to mold the heated fragrance generating substrate into a sheet-like form without cohesive failure, even when using a molding process employing compressive shear force, such as a three-roll press. In order for a heated fragrance generating substrate to achieve these effects, its breaking strength in a tensile strength test must be 0.167 N / mm². 2 The above has been confirmed.

[0027] In order to stably exhibit the above effects by using the first and second binders in combination, it is preferable to have a stepwise manufacturing process for mixing binders that includes a first mixing step of mixing the fragrance source material, aerosol former, and the first binder, and a second mixing step of mixing the second binder into the mixture produced in the first mixing step, or a mixing and molding step of mixing the fragrance source material, aerosol former, and the first binder, and molding the mixture produced in the first mixing step into a heated fragrance generating substrate while mixing in the second binder. The reason for this is not clear, but it is thought that the first binder, a cellulose polysaccharide, promotes the uniform mixing and dispersion of the fragrance source material and aerosol former to form a stable sol state, and then the second binder, a polysaccharide other than a cellulose polysaccharide, forms a gel state that enhances their binding.

[0028] Supporting this hypothesis, when the first and second binders were swapped and mixed, a phenomenon was observed in the mixture of the fragrance source material, aerosol former, and binder, where partially gelled lumps were formed, preventing the creation of a uniform dispersion state.

[0029] Furthermore, it is more preferable to add a curing step immediately after the first mixing step to cure the mixture produced in the first mixing step, and the combined effect of the first and second binders is particularly maximized when the temperature of the curing step is 15°C to 30°C and the curing step duration is 72 hours to 336 hours. This curing step is presumed to have the effect of increasing the degree of dispersion of the fragrance source material in the sol state formed by the first binder, a cellulose polysaccharide, promoting the uniform mixing and dispersion of the fragrance source material and aerosol former, and stabilizing it. This is because an increase in the volume of the mixture is observed during the curing step. Below 15°C, the volume increase is slight, and no effect of the curing step on the quality of the heated fragrance generating substrate is observed, but above 30°C, gelation of the mixture is observed for reasons unknown. Furthermore, for less than 72 hours, the volume increase is minimal, and no effect of the curing process on the quality of the heated fragrance-generating substrate is observed. Beyond 336 hours, this volume increase stops, the effect of the curing process on the quality of the heated fragrance-generating substrate saturates, and further prolonged curing may result in gelation.

[0030] When such a curing process is followed, it is not necessary to add the first and second binders in stages. Instead, a third mixing step is provided in which the fragrance source material, aerosol former, first binder, and second binder are mixed, and a curing step is provided in which the mixture produced in the third mixing step is cured. In this curing step, it is thought that the effect of increasing the dispersion of the fragrance source material by the first binder and the effect of increasing the binding by the second binder occur in parallel.

[0031] The binder is preferably a combination of the above-mentioned cellulosic polysaccharides and other polysaccharides, but it is even more preferable to add cellulose fibers extracted from plants containing a large amount of cellulose fibers. In particular, cellulose fibers from hemp such as linen, jute, molokhia, kenaf, hemp, Manila hemp, and sisal hemp, with a fiber diameter of 10 to 50 μm, as well as cellulose fibers from grasses such as rice, oats, barley, wheat, wild oats, Job's tears, rye, sugarcane, esparto, and bamboo, can homogeneously mix, disperse and bind the materials constituting the heated aroma-generating substrate, imparting the toughness and strength necessary for molding, and are highly effective in preventing deformation, detachment, and falling. Furthermore, rice, wheat, and sugarcane are particularly preferable because they release their aroma when heated.

[0032] Preferably used as aromatic materials are substances that emit an aroma on their own and substances that emit an aroma when heated, and plants and processed products obtained by drying, fermenting, etc., of plants are preferred. Aromatic materials can be broadly classified into tobacco, which belongs to the genus Nicotiana of the Solanaceae family, the above-ground stems and leaves of plants of the same genus, and their components, as well as the flowers, roots, rhizomes, trunks, branches, seeds, fruits, and above-ground stems and leaves of angiosperms, as well as teas, as well as spore-bearing plants, as well as germinated vegetables, and fermented products of grains and beans. It is more preferable to mix two or more aromatic materials, and it is even more preferable to mix three or more materials that have a fragrance defined as an aroma that wafts from the aromatic material itself, an aroma defined as an aroma that wafts into the air when the aromatic material is heated, and a flavor defined as an aroma that wafts in the mouth when the aromatic material is heated. Specific examples of these are listed below.

[0033] Tobacco, a member of the Solanaceae family and genus Nicotiana, and its above-ground stems, leaves, and components, should ideally be used in the smallest possible amount from the perspective of inhaling harmful substances. However, for those who smoke cigarettes, there is a strong tendency to seek the aroma of nicotine and other substances, so it is preferable to use only the minimum necessary amount.

[0034] Non-tobacco plants are selected based on the fragrance of the plant itself and the fragrance released when heated, as there is little need to consider the inhalation of harmful substances. Among the countless flowers of angiosperms, some are selected based on the fragrance of the plant itself and the fragrance released when heated.

However, in some cases, flower buds are preferred over fully bloomed flowers. Furthermore, it's not necessary to use all the parts that make up the flower; you can use only the parts with a particularly strong fragrance, such as the petals, pistil, and stamens.

[0042] Tea varieties, in particular, have a strong aroma, and those made by heating and drying the stems and leaves of plants and then processing them through methods such as rolling, roasting, steaming, and fermentation are preferred, with Japanese tea, Chinese tea, and black tea being especially preferred.

[0043] Furthermore, among teas, fermented Chinese teas and black teas are even more preferable than unfermented Japanese teas. Examples of Chinese teas include Oolong tea (Tieguanyin, Huangjin Gui, Shui Xian, Sezhong), Pu-erh tea, and Jasmine tea, while examples of black teas include Darjeeling, Assam, Uva, Nuwara Eliya, and Keemun. Of these, black tea is the most preferable from the standpoint of aroma.

[0044] Spore-bearing plants include mushrooms, mosses, seaweed, and ferns, all of which are extremely diverse in species, but the following plants are preferred.

Furthermore, the leaves of the following ferns are preferred: horsetail, field horsetail, pine veil, dwarf horsetail, horsetail, ferns, Japanese white ferns, bracken, dwarf ferns, upright ferns, prickly ash, tiger's-foot ferns, dwarf ferns, Japanese cycad, red ferns, double-flowered ferns, star ferns, and dwarf bracken.

[0045] The preferred sprouted vegetables are leguminous sprouts such as soybeans, yaenari, and fenugreek, and cruciferous sprouts such as radish, broccoli, cabbage, mustard, white mustard, watercress, and buckwheat.

[0046] Finally, regarding fermented grains or beans, the options are quite limited, with kōshi, natto, and shinkiku being preferred.

[0047] The aerosol former preferably contains at least one selected from propylene glycol, 1,3-butanediol, sorbitol, ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, glycerin, lactic acid, monoacetin (glycerin monoacetate), diacetin (glycerin diacetate), triacetin (glycerin triacetate), triethylene glycol diacetate, triethyl citrate, isopropyl myristate, methyl stearate, dimethyl dodecanedinioate, and dimethyl tetradecanesanedioate. In particular, propylene glycol, glycerin, and mixtures of propylene glycol and glycerin are preferred.

[0048] It is preferable to add a cooling agent and cross-linked PVP to a heated aroma-generating substrate containing at least such an aroma source, aerosol former, and binder. This is because the volatile components of the cooling agent provide a refreshing flavor in the mouth, resulting in a pleasant smoking experience. Furthermore, the cross-linked PVP has the function of adsorbing the cooling agent, preventing its dissipation over time. Moreover, since the cooling agent is adsorbed onto the cross-linked PVP simply by adding a step of mixing the cooling agent dissolved in a lower alcohol with the cross-linked PVP, a step of adsorbing it onto cyclodextrin is unnecessary.

[0049] Cooling agents include menthol, and menthol derivatives such as menthyl ether, menthyl ester, and menthyl carbonate, as well as menthone and its derivatives, as well as menthane and its derivatives, as well as menthanecarboxylic acid amides such as menthanecarboxylic acid-N-ethylamide [WS3], Nα-(menthanecarbonyl)glycine ethyl ester [WS5], menthanecarboxylic acid-N-(4-cyanophenyl)amide, menthanecarboxylic acid-N-(4-cyanomethylphenyl)amide, and menthanecarboxylic acid-N-(alkoxyalkyl)amide, as well as methyldiisopropylpropionic acid amide [2,3-dimethyl-2-(2-propyl)-butyric acid-N-methylamide [WS 2,3-dimethyl-2-(2-propyl)-butyric acid derivatives such as

[23] , as well as isopulegol and its esters such as (l(-)-isopulegol, l(-)-isopulegol acetate), N-(2-(pyridine-2-yl)ethyl)-3-p-menthanecarboxamide, (1R,2S,5R)-N-(4-methoxyphenyl)-5-methyl-2-(1-isopropyl)cyclohexane-carboxamide [WS12], and carboxamides such as oxamate, as well as L-carbone, xylitol, thymol, spiranthol, etc. can be used. In particular, menthol and / or xylitol produce a flavor that lingers in the mouth, suitable for smoking heated aroma cartridges used with heated smoking devices.

[0050] Furthermore, it is preferable that the heated aroma-generating substrate contains microcrystalline cellulose. Microcrystalline cellulose is a high-purity microcrystalline cellulose obtained by hydrolyzing and purifying pulp with acid. It is a fluid powder that does not dissolve in solvents such as water and ethanol, and is used as an excipient for pharmaceutical tablet molding. This is because the fluidity and high compressibility with large volume changes of microcrystalline cellulose are effective in preventing cohesive failure and adhesion to the mold during tablet molding by direct compression. In the present invention, by adding microcrystalline cellulose, the aroma source material and aerosol former are homogeneously mixed and dispersed via the binder. Therefore, in the production of sheets of heated aroma-generating substrates that can be molded into sheets by compression and shear, for example by a three-roll mill, cohesive failure and adhesion to the metal rolls of the sheet can be effectively prevented.

[0051] Furthermore, since it does not absorb solvents such as water or ethanol, and exists in powder form within the heated fragrance-generating substrate, it can reduce the volume shrinkage of the heated fragrance-generating substrate over time due to drying, etc. Moreover, it acts as a reinforcing material, improving the strength of the heated fragrance-generating substrate. Therefore, it can prevent the heated fragrance-generating substrate from falling off, dropping, or deforming before and after smoking and after long-term storage.

[0052] The heated fragrance-generating substrate must contain at least a fragrance source, an aerosol former, and a binder. However, in order for these to be homogeneously mixed and dispersed, for the binding force to be enhanced, and for the substrate to have the toughness and strength required for molding, there must be specific blending ratios, which were experimentally determined from a number of blending ratios. Specifically, the fragrance source and aerosol former must be present in amounts of 30-90% by mass and 10-40% by mass, respectively, of the heated fragrance-generating substrate. The binders must be present in amounts of 1-30 parts by mass and 0.1-5 parts by mass, respectively, of the first and second binders per 100 parts by mass of the fragrance source. It was also found that the quality can be further improved by including cellulose fibers in the binder in amounts of 1-25 parts by mass per 100 parts by mass of the fragrance source.

[0053] By appropriately blending an appropriate amount of cooling agent and cross-linked PVP into the basic composition of such a heated fragrance-generating substrate, and by adding an appropriate amount of microcrystalline cellulose, the quality of the heated fragrance-generating substrate can be further improved as described above.

[0054] In order to enjoy the cooling sensation of the cooling agent and prevent its dissipation over time, the cooling agent and cross-linked PVP must be present in amounts of 1-10% by mass and 2-10% by mass, respectively, in the heated aroma-generating substrate, and the amount of cross-linked PVP must be 1 to 6 times the amount of the cooling agent. Furthermore, mixing the cooling agent with cross-linked PVP requires dissolving the cooling agent in a lower alcohol before mixing it with the cross-linked PVP. With such content and mixing method, the aroma of the cooling agent can be enjoyed while smoking, the cross-linked PVP can adsorb the cooling agent, and their dissipation over time can be prevented. A quantitative indicator that allows one to determine whether the heated aroma-generating substrate possesses this dissipation prevention effect was found by comparing the heated aroma-generating substrate of the present invention, which uses menthol as a cooling agent, with a conventional heated aroma-generating substrate. This is defined as the menthol reduction rate d = {(d(24)-d(48)} / d(0), where d(0) is the menthol content in a heated fragrance generating substrate weighed at approximately 5g to 10g under conditions of 17°C and 65% RH relative humidity, d(24) is the mass of the heated fragrance generating substrate after being left at 5°C for 24 hours, and d(48) is the mass of the heated fragrance generating substrate after being left at 5°C for 48 hours. The menthol dissipation prevention effect is significant when d ≤ 0.20. Therefore, the heated fragrance generating substrate of the present invention is characterized by having a menthol reduction rate d of d ≤ 0.20. Furthermore, the cooling agents already exemplified exhibit a cooling agent dissipation prevention effect depending on the above-mentioned blending amount and blending method.

[0055] Microcrystalline cellulose needs to be included in the heating aroma-generating substrate at a concentration of 2 to 15% by mass in order to improve the strength of the heating aroma-generating substrate, effectively prevent detachment, falling, and deformation of the heating aroma-generating substrate before and after smoking and after long-term storage, and effectively prevent cohesive failure and adhesion to metal rolls in the sheet manufacturing of the heating aroma-generating substrate by compression and shear processing. While these effects of microcrystalline cellulose can be achieved within this concentration range, it is even more effective if the microcrystalline cellulose has an average particle size of 70 μm to 120 μm and / or a mass-average molecular weight (Mw) of 20,000 to 60,000, and if it has a narrow particle size distribution with a sieve residue amount of 8% by mass or less of the total amount of microcrystalline cellulose on a 250 μm mesh opening, and a sieve residue amount of 45% by mass or more of the total amount of microcrystalline cellulose on a 75 μm mesh opening.

[0056] Since microcrystalline cellulose does not dissolve in water, lower alcohols, aerosol formers, etc., it can be handled in the same way as fragrance sources, so it is preferable to mix microcrystalline cellulose together with fragrance sources and aerosol formers.

[0057] In this invention, microcrystalline cellulose improves the strength of the heated aroma-generating substrate, preventing detachment, falling, and deformation of the heated aroma-generating substrate before and after smoking and after long-term storage. Furthermore, in the production of sheets of the heated aroma-generating substrate by compression and shearing processing, it is possible to prevent cohesive failure of the sheet and adhesion to metal rolls. A quantitative index has been found that allows for the determination of whether the heated aroma-generating substrate possesses this effect. The first quantitative index is the rate of shape change that occurs between the heated aroma-generating substrate before drying, which has a shape of 50 mm in length, 15 mm in width, and 0.3 mm in thickness, and the heated aroma-generating substrate after drying at 105°C for 10 minutes. The second quantitative indicator is the rate of shape change between the heated fragrance-generating substrate before drying, which has a shape of 50 mm in width, 15 mm in width, and 0.3 mm in thickness, and the heated fragrance-generating substrate after drying at 105°C for 15 minutes. The third quantitative indicator is the rate of shape change between the heated fragrance-generating substrate before drying, which has a shape of 12 mm in length, 1.5 mm in width, and 0.3 mm in thickness, and the heated fragrance-generating substrate after drying at 105°C for 10 minutes. The fourth quantitative indicator is the rate of shape change between the heated fragrance-generating substrate before drying, which has a shape of 12 mm in length, 1.5 mm in width, and 0.3 mm in thickness, and the heated fragrance-generating substrate after drying at 105°C for 15 minutes. As a result of comparing the heated aroma-generating substrate of the present invention with conventional heated aroma-generating substrates, it was found that heated aroma-generating substrates whose shape change rate is below a certain limit value exhibit the desired strength, prevent detachment, falling, and deformation of the heated aroma-generating substrate before and after smoking and after long-term storage, and prevent cohesive failure of the sheet and adhesion to metal rolls in compression and shear processing methods. The following shows the allowable ranges for the change rates of length, width, and thickness as specific shape change rates for the first to fourth quantitative indicators.

[0058] The first quantitative indicator of the heated fragrance generating substrate of the present invention is as follows: Using a heated fragrance generating substrate with a shape of 50 mm in length, 15 mm in width, and 0.3 mm in thickness, the length, width, thickness, and volume of the heated fragrance generating substrate before drying are L0 (= 50 mm), W0 (= 15 mm), and T0 (= 0.3 mm), respectively, and the length, width, and thickness of the heated fragrance generating substrate after drying at 105°C for 10 minutes are respectively... When L is 10 mm, W is 10 mm, and T is 10 mm, the length change rate La (%) is defined as {(L0-L10) / L0} × 100, the width change rate Wa (%) is defined as {(W0-W10) / W0} × 100, and the thickness change rate Ta (%) is defined as {(T0-T10) / T0} × 100, and these satisfy the conditions 0% ≤ La ≤ 7.2%, 0% ≤ Wa ≤ 5.7%, and 0% ≤ Ta ≤ 1.2%, respectively.

When the dimensions are mm and T15 mm, the length change rate Lb(%) is defined as {(L0-L15) / L0}×100, the width change rate Wb(%) is defined as {(W0-W15) / W0}×100, and the thickness change rate Tb(%) is defined as {(T0-T15) / T0}×100, respectively, and is characterized by satisfying the following conditions: 0%≦Lb≦8.1%, 0%≦Wb≦6.1%, 0%≦Tb≦1.5%, and 0%≦Vb≦14.3%, respectively.

[0060] The third quantitative indicator of the heated fragrance generating substrate of the present invention is as follows: Using a heated fragrance generating substrate with a shape of 12 mm in length, 1.5 mm in width, and 0.3 mm in thickness, the length, width, thickness, and volume of the heated fragrance generating substrate before drying are L'0 (=12 mm), W'0 (=1.5 mm), and T'0 (=0.3 mm), respectively, and the length, width, and thickness of the heated fragrance generating substrate after drying at 105°C for 10 minutes are L'10 mm, respectively. When W'10mm and T'10mm, the length change rate L'a(%) is defined as {(L'0-L'10) / L'0}×100, the width change rate W'a(%) as {(W'0-W'10) / W0}×100, and the thickness change rate T'a(%) as {(T'0-T'10) / T'0}×100, and these are characterized by satisfying the following conditions: 0%≦L'a≦4.8%, 0%≦W'a≦5.0%, and 0%≦T'a≦1.2%, respectively.

[0061] The fourth quantitative indicator of the heated fragrance generating substrate of the present invention is as follows: Using a heated fragrance generating substrate with a shape of 12 mm in length, 1.5 mm in width, and 0.3 mm in thickness, the length, width, thickness, and volume of the heated fragrance generating substrate before drying are L'0 (=12 mm), W'0 (=1.5 mm), and T'0 (=0.3 mm), respectively, and the length, width, and thickness of the heated fragrance generating substrate after drying at 105°C for 15 minutes are L'15 mm, respectively. When W'15mm and T'15mm, the length change rate L'b(%) is defined as {(L'0-L'15) / L'0}×100, the width change rate W'b(%) as {(W'0-W15) / W'0}×100, and the thickness change rate T'b(%) as {(T'0-T15) / T'0}×100, and these are characterized by satisfying the conditions 0%≦L'b≦5.8%, 0%≦W'b≦5.1%, and 0%≦T'b≦1.5%, respectively.

[0062] As described above, the constituent components, formulation, and characteristics of the heated aroma-generating substrate of the present invention have been explained. As already mentioned, the characteristics of the heated aroma-generating substrate are affected by the manufacturing method. Therefore, the present invention also aims to provide a preferred manufacturing method for a high-quality heated aroma-generating substrate.

[0063] Firstly, the method for producing a heated fragrance generating substrate of the present invention is characterized by comprising a first mixing step of mixing a fragrance source material, an aerosol former, and a first binder; a second mixing step of mixing a second binder with the mixture produced in the first mixing step; and a molding step of molding the mixture produced in the second mixing step into a heated fragrance generating substrate. The reason why such a manufacturing process of mixing different binders in stages is preferred is not entirely clear, but as already explained, it is thought that the cellulose-based first binder promotes the uniform mixing and dispersion of the fragrance source material and the aerosol former to form a stable sol state, and then the polysaccharide-based second binder forms a gel state that enhances their binding.

[0064] Secondly, the method for manufacturing the heated fragrance generating substrate of the present invention is characterized by comprising a first mixing step of mixing a fragrance source material, an aerosol former, and a first binder, and a mixing and molding step of molding the mixture produced in the first mixing step into a heated fragrance generating substrate while mixing in a second binder. This is because the compression and shear molding method allows for uniform mixing and dispersion of the second binder, and also allows for molding into a sheet-like heated fragrance generating substrate, thus eliminating the second mixing step and shortening the manufacturing process.

[0065] Thirdly, the method for producing the heated fragrance generating substrate of the present invention is characterized by providing a curing step immediately after the first mixing step for curing the mixture produced in the first mixing step. In particular, it is preferable that this curing step be carried out at a temperature of 15°C to 30°C and for a time of 72 hours to 336 hours. As already explained, it is presumed that this curing step has the effect of increasing the degree of dispersion of the fragrance source material in the sol state formed by the cellulose-based first binder promoting the uniform mixing and dispersion of the fragrance source material and the aerosol former, and stabilizing it. This is because an increase in the volume of the mixture is observed during the curing step. Below 15°C, the increase in volume is small, and no effect of the curing step on the quality of the heated fragrance generating substrate is observed, but above 30°C, although the cause is unknown, gelation of the mixture is observed. Furthermore, for less than 72 hours, the volume increase is minimal, and no effect of the curing process on the quality of the heated fragrance-generating substrate is observed. Beyond 336 hours, this volume increase stops, the effect of the curing process on the quality of the heated fragrance-generating substrate saturates, and further prolonged curing may result in gelation.

[0066] Fourth, the present invention provides a method for manufacturing a heated fragrance generating substrate, comprising a third mixing step of mixing a fragrance source material, an aerosol former, a first binder, and a second binder; a curing step (Y) of curing the mixture produced in the third mixing step; and a molding step of molding the mixture produced in the curing step into a heated fragrance generating substrate. When a curing step is included, it is not necessary to add the first binder and the second binder in stages, and the manufacturing process can be configured to include a third mixing step of mixing the fragrance source material, an aerosol former, a first binder, and a second binder, and a curing step of curing the mixture produced in the third mixing step. In this curing step, it is considered that the effect of increasing the dispersion of the fragrance source material by the first binder and the effect of increasing the binding by the second binder occur in parallel.

[0067] Fifth, the method for producing a heated fragrance generating substrate of the present invention is characterized in that, in the production method described in the first to fourth sections, when a cooling agent is added to the heated fragrance generating substrate, a fourth mixing step is added in which a cross-linked PVP is mixed into a lower alcohol solution of the cooling agent in order to mix the cooling agent in the first mixing step, the second mixing step, the third mixing step, and the mixing and molding step.

[0068] Finally, we will describe the heated fragrance generating source and heated fragrance cartridge of the present invention, which use the high-quality heated fragrance generating substrate of the present invention manufactured by the above-described components, formulation, and method.

[0069] The heated fragrance source constituting the heated fragrance cartridge of the present invention is characterized by being either a single heated fragrance generating substrate or an aggregate of heated fragrance generating substrates. In the case of a single substrate, the heated fragrance source is preferably in the form of a sheet, and in the case of an aggregate, it is preferable that an appropriate amount of sheet-shaped or cut heated fragrance generating substrates are bundled together. In particular, the shape of the cut heated fragrance generating substrate is not limited to prismatic, flat, cylindrical, or granular shapes, but from the viewpoint of forming a gas flow path, a prismatic shape is preferred. However, in either the sheet-shaped or prismatic shape, in order to ensure a more sufficient gas flow path, it is required that the heated fragrance generating substrate be arranged so that air gaps are connected in the longitudinal direction of the heated fragrance cartridge equipped with the heated fragrance source.

[0070] Such a heated fragrance source may be housed directly in the outer casing that encloses the entire heated fragrance cartridge, or it may be wrapped in a cylindrical wrapped material called a heated fragrance source substrate wrapping member. In the former case, the heated fragrance source substrate is packed into the outer casing, but in the latter case, for example, it only needs to be wrapped in the outer casing, which is efficient in manufacturing the heated fragrance cartridge. The heated fragrance source substrate wrapping member can be made of conventional paper, but in the case of heated smoking devices equipped with a blade-type heat source using a heater, it does not come into contact with the heat source, and the heated fragrance source substrate needs to be aerosol former resistant, so a plastic film is more suitable. In particular, from the standpoint of environmental protection, a biodegradable plastic film is more preferable. As plastics, polyolefins, polyesters, nylons and other plastics and engineering plastics are used, and as biodegradable plastics, poly(3-hydroxybutyrate) (PHB), poly(ε-caprolactone) (PCL), poly(butylene succinate) (PBS), poly(L-lactide) (PLA) Examples include the following. However, in the case of an omnidirectional heat source using electromagnetic induction heating, the entire heated fragrance source of the heated fragrance cartridge is heated to approximately 240°C. Therefore, when using plastic as the wrapping material for the heated fragrance generating substrate, it is necessary to apply a special engineering plastic film with heat resistance equivalent to that of cellulose fibers (which make up paper), which begin glass transition or thermal decomposition at approximately 300°C, i.e., a glass transition temperature of 240°C or higher. Examples of such special engineering plastics include polyamide-imide, polyarylate, polyimide, polytriazine, and liquid crystal polymer.

[0071] Next, the heated aroma generating cartridge of the present invention is characterized in that the heated aroma generating source is housed in a cylindrical heated aroma cartridge outer casing member, and the heated aroma cartridge outer casing member itself forms a mouthpiece. The heated aroma cartridge does not necessarily require a filter member to filter out carbon monoxide, nicotine, tar, and other harmful substances contained in the gaseous and particulate components of the smoke produced by the combustion of tobacco leaves and wrapping paper, as in a cigarette, so the mouthpiece may be simply a hollow space. However, since the cylindrical heated aroma cartridge outer casing member needs to be strong enough to be held in the mouth, it is more preferable to use thick paper or plastic or engineering plastic of appropriate thickness, and even more preferable to use a biodegradable plastic film from an environmental protection standpoint. As plastics and biodegradable plastics, those listed in the heated aroma generating substrate wrapping member can be used. However, while this is applicable to heated smoking devices equipped with a blade-type heat source using a heater, in the case of an omnidirectional heat source using electromagnetic induction heating, the entire heated fragrance source of the fragrance cartridge is heated to approximately 240°C. Therefore, when using plastic as the outer material of the heated fragrance cartridge, as already mentioned, it is necessary to use a special engineering plastic having a glass transition temperature of 240°C or higher.

[0072] Furthermore, the heated fragrance cartridge of the present invention can also be configured such that a mouthpiece is attached to the longitudinal direction of the heated fragrance source and housed in a cylindrical heated fragrance cartridge outer casing member. For the same reason, the mouthpiece may be simply a hollow tube. In this case, thin paper used in conventional cigarettes can be used as the heated fragrance cartridge outer casing member, but the hollow tube is more preferably made of thick paper, or plastic or engineering plastic of appropriate thickness, and even more preferably a biodegradable plastic film from an environmental protection standpoint. In this case as well, as already mentioned, it is necessary to select a plastic for the heated fragrance cartridge outer casing member that is appropriate for the heat source.

[0073] In any of these mouthpieces, it is preferable that they include at least one of the following: a support member to prevent the heated aroma source from moving toward the mouthpiece due to smoking; a cooling member to actively cool the volatile substances of the aerosol former and increase the amount of aerosol generated; and a filter member to filter out carbon monoxide, nicotine, tar, and other off-flavor components generated by heating the heated aroma source, although in small amounts.

[0074] Furthermore, in any of these mouthpieces, the flavor of the heated aroma cartridge can be adjusted in various ways by arranging the support member and cooling member in this order longitudinally from the heated aroma source side, the support member and filter member in this order longitudinally from the heated aroma source side, the cooling member and filter member in this order longitudinally from the heated aroma source side, or the support member, cooling member and filter member in this order longitudinally from the heated aroma source side.

[0075] Furthermore, a mouthpiece comprising at least one selected from a support member, a cooling member, and a filter member can be directly attached to the outer casing of the heated fragrance cartridge, but it is preferable to have it pre-wound in a cylindrical roll of mouthpiece wrapping material, as this facilitates the assembly of the heated fragrance cartridge. Alternatively, the support member, cooling member, and filter member selected for attachment to the mouthpiece may each be individually wound in a cylindrical roll of mouthpiece wrapping material. For such components that do not receive the heat of the heat source, it is possible to replace the conventionally used paper with plastic or engineering plastic, and biodegradable plastic is particularly preferred.

[0076] Furthermore, forming at least one hole on the outer surface of the mouthpiece is also an effective means of adjusting the flavor, inhalation volume, etc., of the heated fragrance cartridge. [Effects of the Invention]

[0077] According to the heated fragrance generating substrate of the present invention, when attaching and detaching a heated fragrance cartridge equipped with a heated fragrance source made therefrom to a heated smoking device, problems such as deformation, detachment, and dropping of the heated fragrance generating substrate do not occur. When smoking, the aroma volatilized from the heated fragrance source material can be fully enjoyed. Furthermore, in the manufacturing of the heated fragrance generating substrate, the fragrance source material, aerosol former, and binder are uniformly dispersed and bonded, and it has the toughness and strength necessary for molding, thus enabling stable production.

[0078] Furthermore, the heated fragrance generating base material of the present invention is characterized in that, when a cooling agent such as menthol or xylitol is added as a fragrance, the dissipation of the cooling agent over time is suppressed. This provides the effect that even after storing a heated fragrance cartridge equipped with a heated fragrance generating source containing this base material for a long period of time, the fragrance of the heated fragrance generating base material can be fully enjoyed when it is attached to a heated smoking device and smoked.

[0079] Furthermore, the heated fragrance generating substrate of the present invention is characterized by minimal dimensional change due to drying. Even after smoking with a heated fragrance cartridge equipped with a heated fragrance generating source made of the substrate, the heated fragrance generating substrate does not detach or fall from the heated fragrance cartridge. Even after long-term storage, the heated fragrance generating substrate does not detach or fall from the heated fragrance cartridge, resulting in excellent handling and preventing contamination of the heat source of the heated smoking device.

The fourth mixing step is to mix cross-linked PVP into the lower alcohol solution of menthol and / or xylitol. [Modes for carrying out the invention]

[0081] The present invention will be described in more detail below with reference to examples, comparative examples, and figures, but the present invention is... The invention is not limited to these examples, and can be implemented with various modifications without departing from the spirit of the present invention. It is possible to do so, and is limited only to the technical concept described in the claims. That is the case.

[0082] Firstly, in order to specifically show the effect of the type of binder and the method of its addition, Examples 1 to 10 In addition, experiments were conducted for Comparative Examples 1 to 4. ≪Example 1≫

[0083] The first binder is methylcellulose and sodium carboxymethylcellulose (CM By the method shown in Figure 9, which involves stepwise mixing C) and the second binder, glucomannan, A heating-activated fragrance-generating substrate was manufactured. Xylitol, used as a cooling agent, was added in the first mixing step. It was added. Therefore, the xylitol aqueous solution was Xylitol 100 parts by mass 400 parts by mass of water It was manufactured by mixing and stirring the ingredients.

[0084] On the other hand, the tea leaves and Gynostemma pentaphyllum leaves, which are the aromatic materials, are prepared to have a moisture content of approximately 2% by mass. The material used was dried at 70°C, then ground, and passed through an 80-mesh sieve. Drying temperature The temperature is preferably in the range of 60°C to 80°C. Within this temperature range, It is easy to reach the desired moisture content while avoiding the dissipation of flavor components. Furthermore, It is more preferable that the temperature be between 65°C and 75°C. Also, the dispersion in the first mixing step To facilitate this process, the dried pulverized material needs to absorb moisture, and that moisture content must be 5% by mass. Preferably, it is less than or equal to 3% by mass, more preferably 0.1% by mass or more. This would be even more preferable.

[0085] In the first mixing step shown in Figure 9, 80 parts by mass of dried and ground black tea leaves Dried and pulverized leaves of Gynostemma pentaphyllum: 20 parts by mass Glycerin 30 parts by mass Propylene glycol 30 parts by mass Methylcellulose 15 parts by mass 4 parts by mass of sodium carboxymethylcellulose (CMC) Xylitol / aqueous solution 8 parts by mass The mixture was placed in a mixer and mixed for 15 minutes to produce the first mixture.

[0086] This first mixture is mixed with a second binder in a second mixing step and a sheet-like heated aroma generation process. It was then fed into a mixed molding process, which also served as the first molding process for shaping the raw material. In the process, 100 parts by mass of the first mixture and 0.5 parts by mass of glucomannan, which is the second binder, are added. Then, while adding 20 parts by mass of water, the doctor blade is pressed against the roll to form a sheet. The process is repeated using a three-roll mill to produce a second mixture, which is a composition of the heated aroma-generating substrate. At the same time, it is formed into a sheet-like heated aroma-generating substrate. In Example 1, this mixed molding During the process, moisture evaporates appropriately, forming a 0.3 mm thick sheet-like heated fragrance generating substrate. To achieve this, a three-roll mill with adjusted roll spacing and inter-roll speed ratio is operated eight times. It was returned. This mixing and molding process is the second mixing step in the manufacturing method shown in Figure 8. 100 parts by mass of the first mixture, 0.5 parts by mass of glucomannan as the second binder, and 20 parts by mass of water. This process combines the mixing of the quantities and the first molding process, in which the material is formed into a sheet using a three-roll mill. This has the advantage of simplifying the manufacturing process shown in Figure 8, but the resulting sheet-like shape There is no difference in the mixing and dispersion state of the heated fragrance-generating substrate.

[0087] Next, in the second molding process shown in Figure 9, this sheet is 150 mm long and 240 mm wide. It is cut into rectangles of mm, and finally, using a rotary cutter, it is cut to a length of 240 mm and a width of 1 mm. Cut into a shape of 0.5 mm and 0.3 mm thick, a long, rectangular prismatic heated aroma-generating substrate is manufactured. The vertical and horizontal directions of this sheet are parallel and perpendicular to the axis of rotation of the roll, respectively. It is in the direction of.

[0088] The 50 long, rectangular prismatic heated aroma-generating substrates 3211 (Figure 3) manufactured in this manner are long Aligned in the direction of the hand, the heated aroma-generating substrate wrapping member 322 has a basis weight of 34 g / Using square meters of paper, the roll is wrapped and glued together to form a cylindrical roll with an outer diameter of 6.9 mm. After the material was manufactured, it was cut to a length of 12.0 mm to produce the heated aroma source 320. As a result, a heated fragrance generating substrate 3 with a length of 12.0 mm, a width of 1.5 mm, and a thickness of 0.3 mm was obtained. 211 (Figure 3) The heated aroma source 320, consisting of 50 pieces wrapped in paper, is a heated aroma source 3 Each of the 20 heating-to-aroma-generating substrate assemblies 321 contains 0.29g, and the heating-to-aroma-generating source The volume filling rate of the heated aroma-generating substrate assembly 321 (Figure 3) relative to the volume of 320 is 0.60 Furthermore, the heated fragrance generating substrate 3211 (Figure 3) was subjected to 100 parts by mass of fragrance source material. The mixture consists of 60 parts by mass of aerosol former, and methylcellulose and CM as the first binder. C is present in 15 parts by mass and 4 parts by mass, respectively, and the second binder, glucomannan, is present in 0.9 parts by mass. It contains a mass portion.

[0089] Here, a wrapping member for a heated fragrance generating substrate wraps around the heated fragrance generating substrate assembly 321. 322 does not need to be paper, but has strength equivalent to paper with a basis weight of 30g / m2 to 40g / m2. A plastic film can be used. Heating aroma-generating substrate wrapping member 322 As described later, the heated aroma-generating substrate 3 does not come into contact with the heat source of the heated smoking device. Because it comes into contact with the aerosol former, which is also an organic solvent contained in 211 (Figure 3), It is preferable to use a plastic film with strength equivalent to that of the paper. In particular, environmental conservation From a protective standpoint, it is preferable to use biodegradable plastic film. However, In the case of plastic films, it is necessary to select a film thickness appropriate to the material. The following is an example. The same applies to the heating-treated aroma-generating substrate wrapping member in the examples and comparative examples. However, this is due to variations. Selected for use with heated smoking devices equipped with a cord-type heat source, It is a selectable material.

[0090] In addition, in Examples 1 to 5 and Comparative Examples 1 and 2, the outer diameter and length of the coated material were as described above. The heat-generating aroma source is processed in the smoking test described later, using a heater. IQOS (registered trademark, manufactured by Philip Morris), which is equipped with a D-type heat source, is a heated smoking device. It is for use. Example 2

[0091] Example 2 uses the exact same composition as Example 1, but in order to specifically demonstrate the curing effect, A heating-to-aroma-generating substrate was manufactured according to a manufacturing process that included the curing step shown in Figure 10. Up to the mixing step, the first mixture is produced in the same manner as in Example 1, but the second mixing step and Before the mixing and molding process, which also serves as the first molding process, the first mixture is sealed in a polyethylene bag. A curing process at 20°C for 144 hours (6 days) was implemented. Through this curing process, The apparent volume increases by approximately 1.5 times, and the cured mixture after the curing process is different from before curing. Visual observation revealed a decrease in the release of crushed tea particles. From this phenomenon, The raw materials consist of an aromatic source, an aerosol former, and methylcellulose, which is the first binder. It is believed that the dispersion of S and CMC has improved.

[0092] The curing mixture produced in this manner is then subjected to the same mixing and molding process as in Example 1, and the second molding process. After the molding process, the heated aroma source 320 was manufactured. As a result, it had a length of 12.0 mm and a width Fifty heated aroma-generating substrate assemblies 321, each 1.5 mm thick and 0.3 mm in diameter, are covered with a paper cover. The heated aroma generating source 320, which is wrapped around the heated aroma generating base material wrapping member 322, is heated Each aroma source 320 contains 0.29 g of heated aroma generating substrate assembly 321, The volume filling ratio of the heated aroma-generating substrate assembly 321 relative to the volume of the heat aroma-generating source 320 is 0. The value was 60. Also, similar to Example 1, the heated aroma-generating substrate 3211 (Figure 3) produced an aroma. For every 100 parts by mass of the source material, 60 parts by mass of the aerosol former and the first binder, methyl Cellulose and CMC are present in amounts of 15 parts by mass and 4 parts by mass, respectively, and a second binder is glycerol. It contains 0.9 parts by mass of lucomannan. <Comparative Example 1>

[0093] Comparative Example 1 specifically demonstrates the effect of the two-step split addition of the first and second binders. The second binder, glucomannan, is added in the first mixing process, rather than in the mixing and molding process of Example 1. Except for mixing the first binder, methylcellulose, and CMC simultaneously, the process is carried out. A heated aroma source was manufactured in the same manner as in Example 1.

[0094] A xylitol aqueous solution for adding xylitol as a cooling agent in the first mixing step. teeth, Xylitol 100 parts by mass 400 parts by mass of water It was manufactured by mixing and stirring. Meanwhile, the aromatic materials, black tea leaves and Gynostemma pentaphyllum leaves, were 7 After drying at 0°C, the material was ground and passed through an 80-mesh sieve. The moisture content of the dried pulverized material was approximately 2% by mass.

[0095] In the first mixing step, 80 parts by mass of dried and ground black tea leaves Dried and pulverized leaves of Gynostemma pentaphyllum: 20 parts by mass Glycerin 30 parts by mass Propylene glycol 30 parts by mass Methylcellulose 15 parts by mass 4 parts by mass of sodium carboxymethylcellulose (CMC) Glucomannan 0.9 parts by mass Xylitol / aqueous solution 8 parts by mass Water 37 parts by mass The mixture was placed in a mixer and mixed for 15 minutes to produce the first mixture.

[0096] The first mixture produced in this manner, unlike in Example 1, is mixed with a second binder. There is nothing else to do; the doctor blade is pressed against the roll and formed into a sheet. The first molding process involves repeating the rolling process, and the roll spacing and inter-roll speed ratio are adjusted. This roll milling process was repeated 8 times, and a 0.3mm thick sheet of material was heated after the moisture had evaporated to an appropriate degree. It was molded into a fragrance-generating substrate.

[0097] Next, similar to Example 1, a heated aroma source was manufactured through a second molding process. As a result, 50 heated aromatics measuring 12.0 mm in length, 1.5 mm in width, and 0.3 mm in thickness were obtained. The generating substrate assembly 321 is wrapped around a paper-based heated fragrance generating substrate wrapping member 322. The heated aroma source 320 emits 0.29g of heated aroma per heated aroma source 320. The raw material aggregate 321 is included, and the volume of the heated aroma generating source 320 is the volume of the heated aroma generating material The volume filling efficiency of aggregate 321 was 0.60. Also, similar to Example 1, the heated aroma generation The raw material 3211 (Figure 3) contains 60 parts by mass of aerosol former per 100 parts by mass of fragrance source material. parts by mass of methylcellulose and CMC, which are the first binders, each in 15 parts by mass and It contains 4 parts by mass of the first binder and 0.9 parts by mass of glucomannan, which is the second binder. ≪Example 3≫

[0098] Example 3 demonstrates that the effect of the present invention does not depend on the cross-sectional shape perpendicular to the longitudinal direction of the heated aroma-generating substrate. To demonstrate this specifically, the width and thickness of the heated aroma-generating substrate were reduced compared to Example 2. Then, in exactly the same manner as in Example 2, after the first mixing step and curing step, the second mixing step was carried out. The second mixture is produced in a mixing and molding process that also serves as the first molding process, and the sheet-like heating process is carried out. It was molded into an aroma-generating substrate. However, in Example 3, the position of the doctor blade and the roll spacing were different. A three-roll mill with different adjustments than in Example 2, including the speed ratio between rolls. This process was repeated 8 times to form a sheet-like heated aroma-generating substrate with a thickness of 0.1 mm. Then, the actual Similar to Example 1, in the second molding process, the material is cut into rectangles measuring 150 mm in length and 240 mm in width. After that, a rotary cutter was used to cut the material to a length of 240 mm, width of 1.0 mm, and thickness of 0.1 mm. A long, rectangular prismatic heating substrate for generating aroma was produced by cutting it into an m-shape.

[0099] In the case of this heated fragrance-generating substrate, 225 strands are aligned in the longitudinal direction, and the basis weight is 34 g / m². It is wrapped and sealed with two pieces of paper, forming a cylindrical roll with an outer diameter of 6.9 mm. After the item was manufactured, it was cut to a length of 12.0 mm. As a result, the length was 12.0 mm, and the width was... The 225 heated aroma-generating substrate aggregates 321, each 1.0 mm thick and 0.1 mm in diameter, are made of paper. The heated aroma generating source 320, which is wrapped around the heated aroma generating base material wrapping member 322, Each heat fragrance generating source 320 contains 0.29 g of heated fragrance generating substrate assembly 321, The volume filling ratio of the heated aroma-generating substrate assembly 321 relative to the volume of the heated aroma source 320 is 0.6 The result was 0. Naturally, the composition of the heated aroma-generating substrate 3211 (Figure 3) in this case was also the same as in Example 1. And 2, as well as Comparative Example 1, are the same. Example 4

[0100] In Example 4, the effect of the present invention does not depend on the cross-sectional shape perpendicular to the longitudinal direction of the heated aroma-generating substrate. To demonstrate this specifically, the width and thickness of the heated aroma-generating substrate were increased compared to Example 2. Then, in exactly the same manner as in Example 2, after the first mixing step and curing step, the second mixing step was carried out. The second mixture is produced in a mixing and molding process that also serves as the first molding process, and the sheet-like heating process is carried out. It was molded into an aroma-generating substrate. However, in Example 4, the position of the doctor blade and the roll spacing were different. A three-roll mill with different adjustments than in Example 2, including the speed ratio between rolls. This process was repeated 8 times to form a sheet-like heated aroma-generating substrate with a thickness of 0.5 mm. Then, the actual Similar to Example 1, in the second molding process, the material is cut into rectangles measuring 150 mm in length and 240 mm in width. After that, a rotary cutter was used to cut a piece that was 240mm long, 2.0mm wide, and 0.5mm thick. A long, rectangular prismatic heating substrate for generating aroma was produced by cutting it into an m-shape.

[0101] In the case of this heated fragrance-generating substrate, 23 strands are aligned in the longitudinal direction, and the basis weight is 34 g / m². It is wrapped and glued together with paper #2, resulting in a cylindrical roll with an outer diameter of 6.9 mm. After the item was manufactured, it was cut to a length of 12.0 mm. As a result, the length was 12.0 mm, and the width was... 23 heated fragrance generating substrates 321, each 2.0 mm in diameter and 0.5 mm thick, are made of paper. The heated fragrance source 320, which is wrapped around the fragrance generating base material wrapping member 322, is a heated fragrance generating Each raw material 320 contains 0.30g of heated aroma-generating base material assembly 321, and heated aroma The volume filling ratio of the heated aroma-generating substrate assembly 321 relative to the volume of the source 320 was 0.62. Naturally, the composition of the heated fragrance generating substrate 3211 (Figure 3) in this case is also the same as in Examples 1 and 2. Furthermore, it is the same as Comparative Example 1. <Comparative Example 2>

[0102] Comparative Example 2 was conducted without using glucomannan to confirm the effect of the second binder. We attempted to manufacture a heated aroma-generating substrate in the same manner as in Comparative Example 1, but using a three-roll mill. In the first molding process, breakage and peeling occur, making it difficult to form a sheet, and glucomannan It was found that it is a heat-activated aroma-generating substrate and an essential binder for its manufacture. However, To conduct the smoke test, a heated aroma source of the same size as in Examples 1 and 2, and Comparative Example 1 was used. They manufactured it. Example 5

[0103] In Example 5, in order to specifically demonstrate the magnitude of the influence of curing, the manufacturing process of Comparative Example 1 was modified to include curing. A fresh processing step was added. Specifically, the first mixture in Comparative Example 1 was sealed in a polyethylene bag. Furthermore, a curing process of 20°C for 144 hours (6 days) was implemented. By going through this curing process... As a result, the apparent volume increases by approximately 1.4 times, and the cured mixture after the curing process is compared to before curing. Visual observation revealed a decrease in the amount of loose powdered tea particles. Ultimately, It was molded in the same manner as in Example 1, with a length of 12.0 mm, a width of 1.5 mm, and a thickness of 0.3 mm. A collection of 50 heated fragrance generating substrates 321 is a paper-based heated fragrance generating substrate wrapping section. A heated aroma source 320 wrapped around material 322 is manufactured, and one heated aroma source 320 Each unit contains 0.29 g of heated fragrance generating substrate assembly 321, and the heated fragrance generating source 320 The volume filling ratio of the heated aroma-generating substrate assembly 321 relative to the volume was 0.60. Similar to Examples 1-4 and Comparative Example 1, the heated fragrance generating substrate 3211 (Figure 3) is a fragrance source material. In contrast, 60 parts by mass of aerosol former, methylcellulose as the first binder and CMC is present in 15 parts by mass and 4 parts by mass, respectively, and the second binder, glucomannan, is present in 0 parts by mass. Contains 0.9 parts by mass.

[0104] Examples 1 to 5 described above, as well as Comparative Examples 1 and 2, were used in the smoking test described later, with the heater A blade-type heat source was molded for evaluation using IQOS®. However, depending on the heat source, the heating method, the maximum temperature reached, and the heated aroma source and the heated The composition of the fragrance cartridges may differ, which could potentially affect the evaluation results. Therefore, although it is the same heated smoking device, Glo (registered trademark) uses electromagnetic induction heating as an omnidirectional heat source. Evaluation using ) was also performed. Examples 6-10, and Comparative Examples 3 and 4, showed that the aroma generated when heated was Regarding the composition of the base material and its manufacturing method, Examples 1 to 5 and Comparative Example 1 and Corresponding to 2, but molded into a heated aroma source compatible with Glow (registered trademark). . ≪Example 6≫

[0105] A 0.3 mm thick sheet-like heated aroma-generating substrate, manufactured in exactly the same manner as in Example 1, is the first In the molding process of step 2, after being cut into a rectangle measuring 150 mm in length and 210 mm in width, a rotary - Using a cutter, it is cut into pieces with a length of 210 mm, a width of 1.5 mm, and a thickness of 0.3 mm. A long, rectangular prismatic heating substrate for generating aroma was manufactured.

[0106] This heated fragrance-generating substrate consists of 31 strands aligned in the longitudinal direction, and is made of paper with a basis weight of 34 g / m2. By being rolled up, wrapped, and glued, a cylindrical roll with an outer diameter of 5.5 mm is produced. After being manufactured, it was cut to a length of 42.0 mm, and the heated aroma source 420 was produced. As a result, 31 heated aroma-generating materials were produced, each measuring 42.0 mm in length, 1.5 mm in width, and 0.3 mm in thickness. The base material assembly 421 is wrapped around a paper heated fragrance generating base material wrapping member 422. The aroma source 420 contains 0.63g of heated aroma generating group per heated aroma source 420. The material aggregate 421 is included, and the volume of the heated aroma generating source 420 is the aggregate of the heated aroma generating substrate The volume filling efficiency of body 421 was 0.59. There was no change in the composition of the heated aroma-generating substrate. The mixture consists of 100 parts by mass of fragrance source material, 60 parts by mass of aerosol former, and a first binder. Methylcellulose and CMC are present in amounts of 15 parts by mass and 4 parts by mass, respectively, as a second binder. It contains 0.9 parts by mass of glucomannan.

[0107] Here, a wrapping member for a heated fragrance generating substrate wraps around the heated fragrance generating substrate assembly 421. 422 does not need to be paper, but has strength equivalent to paper with a basis weight of 30g / m2 to 40g / m2. Plastic film can be used. However, omnidirectional heat source by electromagnetic induction heating In this case, unlike a blade-type heat source using a heater, the heated fragrance cartridge The entire source 420 and the heated fragrance cartridge outer casing 410 are heated to approximately 240°C. Therefore, plastic film, engineering plastic film, biodegradable plastic Stick film cannot be used as a substitute material for paper. In this case, heating When using plastic as the wrapping material for the fragrance-generating substrate, glass rolling at approximately 300°C Heat resistance equivalent to that of cellulose fibers (which make up paper), in which translocation or thermal decomposition begins, i.e., A special engineering plastic film with a glass transition temperature of 240°C or higher is applied. It is necessary to do so. Examples of such special engineering plastics include polyamide. Examples include polyamides, polyarylates, polyimides, polytriazines, and liquid crystal polymers. Cut. Example 7

[0108] Example 7 also specifically demonstrates the effect of curing compared to Example 6, and confirms the effect of curing. A 0.3 mm thick sheet-like heated aroma-generating substrate, manufactured in exactly the same manner as in Example 2, is the first In the molding process of step 2, after being cut in exactly the same way as in Example 6, the heated aroma source 4 is used in exactly the same way. 20 were manufactured. The result is a length of 42.0 mm, a width of 1.5 mm, and a thickness of 0.3 mm. 31 heated fragrance generating substrate assemblies 421 are wrapped in paper heated fragrance generating substrate wrapping material 4 The heated aroma source 420 wound around 22 is 0.6 per heated aroma source 420. It contains 3 g of heated fragrance generating substrate assembly 421, and the volume of heated fragrance generating source 420 The volume filling ratio of the heated aroma-generating substrate assembly 421 was 0.59. The composition was the same as in Example 6. It has the same composition as the heated fragrance-generating substrate. <Comparative Example 3>

[0109] Comparative Example 3 also specifically demonstrates the effect of the two-stage split addition of the first and second binders, A 0.3 mm thick sample was manufactured in exactly the same manner as Comparative Example 1, which confirmed the effect of two-stage divided addition. The heat-heated aroma-generating substrate in the form of a sheet is cut in the second molding step in exactly the same manner as in Example 6. Subsequently, a heated aroma source 420 was manufactured in exactly the same manner. As a result, a length of 42.0 mm and a width of 1 mm was produced. A collection of 31 heated aroma-generating substrates 421, each 0.5 mm thick and 0.3 mm in diameter, is made of paper. The heated fragrance source 420, which is wrapped around the heat fragrance generating substrate wrapping member 422, is heated fragrance Each fragrance source 420 contains 0.63g of heated fragrance generating substrate assembly 421, and is heated The volume filling ratio of the heated aroma-generating substrate assembly 421 relative to the volume of the aroma-generating source 420 is 0.5 The result was 9. The composition is the same as that of the heated aroma-generating substrate in Example 6. Example 8

[0110] Compared to Example 7, Example 8 also shows the influence of the cross-sectional shape perpendicular to the longitudinal direction of the heated aroma-generating substrate. The purpose is to confirm the influence of the cross-sectional shape perpendicular to the longitudinal direction of the heated aroma-generating substrate. A 0.1 mm thick sheet-like heated aroma generator, manufactured in exactly the same manner as in Example 3 to be examined. In the second molding process, the material is cut into rectangles measuring 150 mm in length and 210 mm in width, Using a rotary cutter, cut the material into a shape measuring 210mm in length, 1.0mm in width, and 0.1mm in thickness. A long, rectangular prismatic heated aroma-generating substrate was produced. This heated aroma-generating substrate is 1 The 42 pieces were aligned lengthwise, wrapped in 34 g / m2 paper, and then glued. After being processed, a cylindrical roll with an outer diameter of 5.5 mm was produced, and then it was made to a length of 42.0 m. It was cut into m pieces, and a heated aroma source 420 was manufactured. As a result, it had a length of 42.0 mm and a width 142 heated aroma-generating substrate assemblies 421, each 1.0 mm thick and 0.1 mm thick, are made of paper. The heated aroma generating source 420, which is wrapped around the heated aroma generating substrate wrapping member 422, Each heat fragrance generating source 420 contains 0.64 g of heated fragrance generating substrate assembly 421, The volume filling rate of the heated aroma-generating substrate assembly 421 relative to the volume of the heated aroma-generating source 420 is 0 The value was 0.60. The composition is the same as that of the heated aroma-generating substrate in Example 6. ≪Example 9≫

[0111] Compared to Example 7, Example 9 also shows the influence of the cross-sectional shape perpendicular to the longitudinal direction of the heated aroma-generating substrate. The purpose is to confirm the influence of the cross-sectional shape perpendicular to the longitudinal direction of the heated aroma-generating substrate. A 0.5 mm thick sheet-like heated aroma generator manufactured in exactly the same manner as in Example 4 to be examined. In the second molding process, the material is cut into rectangles measuring 150 mm in length and 210 mm in width, Using a rotary cutter, the shape is cut to a length of 210 mm, a width of 2.0 mm, and a thickness of 0.5 mm. A long, rectangular prismatic heating substrate for generating aroma was produced by cutting the material.

[0112] This heated fragrance-generating substrate consists of 14 strands aligned in the longitudinal direction, and is made of paper with a basis weight of 34 g / m2. By being rolled up, wrapped, and glued, a cylindrical roll with an outer diameter of 5.5 mm is produced. After being manufactured, it was cut to a length of 42.0 mm, and a heated aroma source was produced. As a result, 142 heated fragrance generating substrates, each measuring 42.0 mm in length, 2.0 mm in width, and 0.5 mm in thickness. The aggregate 421 is wrapped around a paper-based heated fragrance generating substrate wrapping member 422, which is a heated fragrance The fragrance source 420 consists of a collection of 0.63g of heated fragrance generating substrate per heated fragrance source 420. The combined 421 is included, and the volume of the heated aroma generating source 420 is the volume of the heated aroma generating substrate 4 The volume filling rate of 21 was 0.59. The composition was the same as that of the heated aroma-generating substrate in Example 6. It is complete. <Comparative Example 4>

[0113] Since it has the same composition as Comparative Example 2, which was used to confirm the effect of the second binder, the composition is as shown in Comparative Example 2. Although the product was in a shaped state, a smoking test was conducted to confirm the effect of the heat source. Example 6, Actual A heated aroma source of the same size as that used in Example 7 and Comparative Example 3 was manufactured. Example 10

[0114] Example 10 also aims to confirm the magnitude of the influence of curing, A 0.3 mm thick sheet-like heated aroma generator, manufactured in exactly the same manner as in Example 5, confirms the process. The base material is cut in exactly the same way as in Example 6 during the second molding process, and then coated in exactly the same way. A thermal fragrance source was manufactured. As a result, it measured 42.0 mm in length, 1.5 mm in width, and 0.3 mm in thickness. A collection of 31 heated fragrance generating substrates 421 is a paper-based heated fragrance generating substrate wrapping section. The heated aroma source 420 wrapped around the material 422 is 0 It contains a heated aroma-generating substrate assembly 421, and the volume of the heated aroma-generating source 420 is The volume filling ratio of the heated aroma-generating substrate assembly 421 was 0.60. The composition is as follows: It has the same composition as the heated aroma-generating substrate of 5.

[0115] The above examples 1 to 10, and in order to specifically illustrate the effects of the type of binder and the method of addition, Although heated aroma sources like those in Comparative Examples 1-4 were manufactured, furthermore, different types of binders were used. When we also tried to consider the mixing order, we found that in the first mixing process similar to Example 1, cellulose The first binder of the cellulose polysaccharide is replaced with a second binder that is a polysaccharide other than a cellulose polysaccharide. When the agent was replaced, a partially gelled mass was formed, and the odor persisted in subsequent processes. Because it remained even after heating, it was not possible to produce a uniform heating substrate for generating aroma, therefore, as a comparative example... Details have been omitted.

[0116] Using the heated aroma sources of Examples 1 to 10 and Comparative Examples 1 to 4, the first binder and To specifically demonstrate the effects of the stepwise addition of the second binder, as well as the effects and influences of the curing process. To enable this, the following evaluations 1-3 were conducted. [Rating 1-1]

[0117] To evaluate the heated aroma sources of Examples 1-5 and Comparative Examples 1 and 2, see Figure 1. This shows a heated coffee machine equipped with a blade-type heat source 130 using a heater manufactured by Philip Morris. The smoking device, IQOS® 100, was used. This smoking device 100 has a heat source 130, A heated blade type with a width of 4.5mm, a length of 12mm to the tip, and a thickness of 0.4mm. This is the heat source 130, which is located on the opposite side of the chamber of the body 110 (as shown in the figure). (Not present) The electricity supplied from the battery generates heat, reaching approximately 300-350°C. The heated fragrance cartridge 300 has an inner diameter of 7.0 mm in the chamber provided in the body 110. After being mounted so as to conform to 120 on the inner surface of m, the control system built into the body 110 The stem allows you to smoke one heated fragrance cartridge (300) in 14 puffs. Furthermore, when the heated fragrance cartridge 300 of this embodiment and comparative example is inserted, the body The length of the part that protrudes outward from the E110 is approximately 20 mm.

[0118] On the other hand, the heated fragrance cartridge 300 attached to this smoking device is, as shown in Figure 1, The heated aroma source 320, the support member 331, and the filter member 333 are heated aroma source The cartridge is wrapped with the outer casing member 310, and the mouthpiece 33 is reinforced with the mouthpiece reinforcing member 3301. The configuration was reinforced with 0. More specifically, in Examples 1 to 5 and Comparative Examples 1 and 2, A heated aroma source 320 was created with a length of 12 mm and an outer diameter of 6.9 mm, and a cylindrical inner diameter of 4 mm. Support member 331 is a hollow tube with a length of 8 mm and an outer diameter of 6.9 mm, having a through hole, and length A cylindrical shape made of cellulose acetate fibers, with a diameter of 23 mm and an outer diameter of 6.9 mm. The filter members 333 are attached in this order in the longitudinal direction, and these are positioned in predetermined locations that will become the inner surface. The outer casing of the heated fragrance cartridge is made of 38 g / m2 paper with a fixed amount of adhesive applied. The component 310 is wound so that the outer diameter is slightly less than 7.0 mm, and further, the mouthpiece 330 The inner surface of the 333 section of the router is coated with adhesive and the paper has a basis weight of 40 g / m2. It was manufactured in a rolled form. In this case, the basis weight of the heated fragrance cartridge outer component 310 is Paper with a density of 32 g / m² to 45 g / m², or a plastic film with equivalent strength. Using is preferable to maintain the minimum necessary strength, but the part that is held in the lips, To prevent damage from saliva penetration, it is preferable to reinforce the surface with paper with a basis weight of 40 g / m2 or more. The heated fragrance cartridge outer casing 310 does not come into contact with the heat source 130, therefore A plastic film can be used that is appropriate for the strength of each type of paper. The tic film does not allow saliva to penetrate and therefore does not require the mouthpiece reinforcing member 3301. It is preferable. In particular, from the standpoint of environmental protection, using biodegradable plastic film is preferable. This is even more preferable. However, in the case of plastic films, the film thickness should be selected according to the material. It is necessary.

[0119] In the case of the blade-type heat source 240, a drop test is performed on the heated fragrance generating substrate 3211 (Figure 3). The effects of the binder and curing were confirmed. This was done using a blade-type heat source 130 as shown in Figure 1. In this case, the heated fragrance generating substrate assembly 321 comes into contact with the blade-type heat source 240 and is heated. Therefore, the heated aroma-generating substrate 3211 (Figure 3) after smoking tends to shrink and fall off. In addition to having a direction, the aroma-generating substrate assembly 321 that is heated during smoking is a blade-type heat source 130 and This is based on the tendency to contaminate the inner wall 120 of the chamber. The evaluation is for Examples 1-5. Furthermore, a heated fragrance car equipped with the heated fragrance source 320 manufactured in Comparative Examples 1 and 2. The cartridge 300 is attached to the heated smoking device 100 equipped with a blade-type heat source 130, and smoking After this is done, the heated fragrance cartridge 300 is removed, and the heated fragrance source 320 is led By directing the object directly downwards, we can check whether or not the heated fragrance generating substrate 3211 (Figure 3) has fallen. It was done.

[0120] The criteria for this evaluation are as follows: Rank A: No dropping of heated fragrance-generating substrate, and no contamination of the blade-type heat source and the inner wall of the chamber. dye few Rank B: A portion of the heated aroma-generating substrate falls off, affecting the blade-type heat source and the inner wall of the chamber. pollution is noticeable [Rating 1-2]

[0121] To evaluate the heated aroma source in Examples 6-10 and Comparative Examples 3 and 4, electromagnetic As a heated smoking device equipped with an omnidirectional heat source using induction heating, as shown in Figure 2, British The device used was the Glo® 200 manufactured by American Tobacco. This smoking device, the Glo 200, has a body An omnidirectional heat source 24 is provided by electromagnetic induction heating along the inner surface 220 of the chamber 210. A 0 is provided, and a heated fragrance cartridge 400 is attached to this heat source 240, and the heated fragrance The area around the fragrance source 420 is heated. The heat is supplied from the heat source control unit 250. It generates heat through electricity, reaching a temperature of approximately 240-280°C, and takes about 3-4 minutes to smoke. Yes. The heated fragrance cartridge 400 has a vent hole 230 at the bottom and is lidless, with an inner diameter of 5. After being mounted on the 6mm cylindrical heat source 240, it was heated by the heat source control unit 250. Aerosol former volatilizes from the heated aroma source 420, which is surrounded by the heat source 240, and is then inhaled. Then, the air flowing in through the vent 230 cools the aerosol former, generating smoke and causing inhalation. It can be smoked.

[0122] On the other hand, the heated fragrance cartridge 400 attached to this smoking device is, as shown in Figure 2, A heated aroma source 420, a cooling member 432, a filter member 433, and a hollow tube 434 A mouthpiece 430 consisting of the above is wrapped with a heated fragrance cartridge outer casing member 410. The composition was as follows: More specifically, the length produced in Examples 6 to 10 and Comparative Examples 3 and 4 A heated aroma source 420, with a thickness of 42mm, outer diameter of 5.5mm, length of 25mm, and thickness of 0.5mm. Cooling element 432, made by rolling up cardboard to form a cylindrical shape with an outer diameter of 5.5 mm, length 8 mm, outer diameter 5. Filter member 433 made of cellulose acetate fibers molded into a 5 mm cylindrical shape. And, a cylindrical shape with an outer diameter of 5.5 mm formed by rolling up cardboard that is 8 mm long and 0.5 mm thick. The empty tubes 434 are attached in this order along the longitudinal direction, and a predetermined amount of adhesive is applied to the predetermined positions on the inner surface. A heated fragrance cartridge made of paper measuring 20 mm in length and 83 mm in width with a basis weight of 38 g / m2, coated with a special coating. The outer casing member 410 was wrapped around the material to have an outer diameter of slightly less than 5.6 mm.

[0123] In the case of the omnidirectional heat source 240, an insertion test of the heated fragrance cartridge 400 is performed to confirm the connection. The effects of the agent and curing were confirmed. This was done using a cylindrical, omnidirectional heat source 24, as shown in Figure 2. If the value is 0, insert the elongated heated fragrance cartridge 400 into the elongated cylindrical can. Therefore, it is difficult to install the heated fragrance cartridge 400, and in some cases, This is based on the fact that it may lead to damage. The evaluation is based on the heating when smoking. To ask five subjects about their experience attaching the heated aroma cartridge 400 to the smoking device 400. It was done by [the person / organization].

[0124] The criteria for this evaluation are as follows: Rank A: No problems with the installation of the heated fragrance cartridge. Rank B: Difficulty in installing the heated fragrance cartridge, and in some cases, damage may occur. [Rating 2-1]

[0125] In the smoking survey conducted in [Evaluation 1-1], a sensory evaluation was performed on 5 subjects, and the results were combined. The effects of the agent and the treatment were confirmed. The sensory evaluation focused particularly on the delicate aroma emitted by tea. It broke.

[0126] The criteria for this evaluation are as follows: Rank A: A level where you can enjoy the aroma of tea while smoking. Rank B: The aroma of tea is not strong enough when smoking. [Rating 2-2]

[0127] In the case of the omnidirectional heat source 240, the same conditions as in the case of the blade-type heat source 130 are as shown in Figure 2. The effects of the binder and the health treatment were confirmed by having five subjects smoke and conducting a sensory evaluation. In this case as well, a sensory evaluation was conducted that focused on the delicate aroma emitted by the tea.

[0128] The criteria for this evaluation are as follows: Rank A: A level where you can enjoy the aroma of tea while smoking. Rank B: The aroma of tea is not strong enough when smoking. [Rating 3]

[0129] The effects of the binder and curing were evaluated in evaluations 1 and 2, including a drop test of the heated fragrance-generating substrate, and The effects of these tests were confirmed through insertion tests and smoking tests of heated fragrance cartridges. The power of the sheet-like heated aroma-generating substrates produced in Examples 1-10 and Comparative Examples 1-4 We found a correlation with academic strength.

[0130] In fact, Examples 1, 2, 5, 6, 7, and 10, which were manufactured to a thickness of 0.3 mm, For the comparison, the sheet-like heated aroma-generating substrates of Comparative Examples 1-4 were used, with dimensions of 10.0 cm in width and 22.0 cm in length. A general tensile strength test was performed using test specimens cut to length m, and the measured breaking strength was evaluated. The tensile strength test was performed with a clamping distance of 20.0 cm between the clamps that gripped the specimen in the longitudinal direction. The test was conducted in a test environment of °C and 50% RH. Breaking strength was measured when a crack or other defect appeared in the test specimen and fracture began. This was defined as the intensity of [the substance].

[0131] The compositions of Examples 1-10 and Comparative Examples 1-4 used in Evaluations 1-3 are described above, and contribution [Table 1-1] Table 1-1 shows the shape and number of heated fragrance generating substrates used as a heat fragrance generating source. Table 1-2 shows the manufacturing conditions for the raw material composition and the results of evaluations 1-3. [Table 1-2]

[0132] The method of adding the binder was compared between Example 1 and Comparative Example 1, and between Example 6 and Comparative Example 3. This confirms that it is preferable to add the first and second binders in stages. The first binder and the second binder were added in two steps, as in Example 1 and Comparative Example 1. The latter is a heated aroma-generating substrate manufactured under exactly the same conditions except that it is added all at once. In a drop test and smoking test using a heated smoking device 100 equipped with a blade-type heat source 130, In this case, the former yielded superior results. Also, Example 6 and Comparative Example 3 are, The relationship between 1 and Comparative Example 1 is similar, and the heated smoking device 200 is equipped with an omnidirectional heat source 240. In the insertion test and smoking test used, the composition produced by the two-step addition of the binder was used. Better results have been obtained with the heated aroma-generating substrate manufactured from [the specified material].

[0133] The reason for this is unclear, but the first binder of the cellulosic polysaccharide is the fragrance source and aero The solformer promotes uniform mixing and dispersion to form a stable sol state, and then the cellulose A second binder, which is a polysaccharide other than the syl-based polysaccharides, forms a gel state that enhances the binding of these molecules. Therefore, the dense dispersion enhances the volatilization of aromatic components in tea when heated, and the binding force is This is thought to reduce the shrinkage effect caused by heating and improve the mechanical strength of the aroma-generating substrate. This speculation suggests that if the first binder and the second binder are swapped and mixed, the fragrance source material, E A partially gelled mass is formed in the mixture of allosolformer and binder, resulting in a uniform dispersion. This is supported by the phenomenon of being unable to generate a state.

[0134] The effectiveness of the curing process was compared between Examples 1 and 2-4, and between Example 5 and Comparative Example 1, comparing the presence or absence of curing. For Examples 6 and 7-9, and Example 10 and Comparative Example 3, evaluations 1-1 and 1 -2, the results of evaluation 2-1 and evaluation 2-2 make this clear. Curing is done with a stepwise binder. Similar to the addition of [another substance], the quality of the heated aroma-generating substrate can be greatly improved. Also, Example 5 and As can be seen by comparing the evaluation results of Comparative Example 1 and Example 10 with those of Comparative Example 3, the curing process When this process is followed, there is no need to add the first and second binders in stages, and the curing effect is It is thought to be quite large.

[0135] Although the cause of this curing effect is not clear, the cellulose-based first binder promotes uniform mixing and dispersion of the aroma source material and aerosol former in the sol state formed, which is presumed to result from increasing the degree of dispersion of the aroma source material and stabilizing the dispersion. This is supported by the finding that volume increase of the mixture is observed during the curing process, and the volume increase depends on the curing temperature and time As a result, it is considered that the denser dispersion structure of the aroma source material in the heatable aroma-generating base material produced through the curing process enhances the volatilization effect of the aromatic components of tea by heating, reduces the shrinkage effect of the heatable aroma-generating base material caused by heating, and improves the mechanical strength of the heatable aroma-generating base material .

[0136] Furthermore, from the evaluation results of Comparative Examples 2 and 4 in which glucomannan was not added, polysaccharides other than cellulose-based polysaccharides used as the second binder are added in a small amount, but are considered to be indispensable for improving the quality of the heatable aroma-generating base material . However, addition of a large amount of such a polysaccharide as the second binder destroys the dispersion system of the composition of the heatable aroma-generating base material, and tends to cause gelation. Therefore, it is necessary to use the first binder in combination with the cellulose-based polysaccharide to improve the dispersibility and binding force of the heatable aroma-generating base material .

[0137] Furthermore, to support the causal relationship between such drop tests, insertion tests, and smoking tests, it has been found that these evaluation results have a good correlation with the breaking strength of the sheet-shaped heatable aroma-generating base materials produced in Examples 1 to 10 and Comparative Examples 1 to 4. The results are shown in the column of tensile test in Table 1-2 for Examples 1, 2, 5, 6, 7, and 10, as well as Comparative Examples 1 and 2 This evaluation 3 is compared with evaluation results 1-1, 1-2, 2-1, and 2-2. Breaking strength of a sheet-like heated fragrance generating substrate manufactured by two-stage addition of a binder and curing. The degree is high, and the cross-sectional area of ​​the test piece (0.3 × 100 mm) 2 ) at least 5N or more per unit, in other words 0.167 N / mm 2 The heated fragrance cartridge has the above breaking strength. The required mechanical strength, low heat shrinkage after smoking, and aroma due to heating during smoking are also considered. This is thought to be an indicator for the volatility of the components. This indicator is as described above. The effects of the stepwise addition of the binder and curing are not inconsistent with, but rather correlated with, the cause of the problem.

[0138] Secondly, cross-linked PVP allows for the sorption of cooling agents through a simple process, and when heated, it generates an aroma. The heating element is equipped with a heating element that suppresses the time-dependent dissipation of the cooling agent from the substrate and contains it. Even after storing the fragrance cartridge for a long period of time, when it is attached to a heated smoking device and smoked, it will not be heated. In order to specifically demonstrate the effect of being able to fully enjoy the fragrance of the fragrance generating base material, a cooling agent and Examples 11-18 using menthol and xylitol, and Comparative Examples 5-12 An experiment was conducted.

[0139] As shown in Figure 12, the method for producing the heated aroma-generating substrate of the present invention involves a first binder and The second binder is added in stages, along with the first mixing step of adding the first binder and the second It is optimal to include a curing step between the second mixing step, in which the binder is added. In the following examples and comparative examples, the focus is solely on verifying the effects of crosslinked PVP, and the experiments have been simplified. To achieve this, the first and second binders are added together, eliminating the curing process, Only menthol was used as a cooling agent. The process diagram in Figure 11, which omits the curing process, is shown in Figure 12. We adopted a manufacturing process that incorporates a fourth mixing step. ≪Example 11≫

[0140] The fourth mixing step, which involves mixing a lower alcohol containing a cooling agent with cross-linked PVP, is as follows: I went and did that. Menthol 100 parts by mass Ethyl alcohol 200 parts by mass Cross-linked polyvinylpyrrolidone (PVP) 200 parts by mass Weigh the ingredients, dissolve the menthol in ethyl alcohol, and dissolve the menthol in ethyl alcohol. After preparing the liquid, add the cross-linked PVP to the menthol / ethyl alcohol solution and stir-mix.

Compression by being pressed between narrow rolls and shearing by the difference in roll speed result in uniform kneading and dispersion, producing a sheet-shaped heatable aroma-generating base material of a predetermined thickness. Note that In the first forming step, since the composition becomes a high-viscosity paste, pure water is added while checking the state of the sheet in an appropriate amount, and forming into a sheet shape is performed by pressing a doctor blade against the roll . In this forming step, the three-roll mill, whose roll gap, speed ratio between rolls and other parameters are adjusted so that an appropriate amount of water evaporates and the material is formed into a sheet-shaped heatable aroma-generating base material with a thickness of 0.3 mm was repeated 8 times.

[0144] The sheet-shaped heatable aroma-generating base material produced in the first forming step is fed into the second forming step and is first cut into a rectangle of 150 mm in length and 240 mm in width. Further, the sheet cut into this rectangle is cut using a rotary cutter into pieces of 240 mm in length, 1.5 mm in width, and 0 .3 mm in thickness, producing elongated prismatic heatable aroma-generating base materials.

This was done to demonstrate the effect. That is, as in Example 11, it was dissolved in ethyl alcohol. Menthol is mixed with cross-linked PVP, causing the cross-linked PVP to swell. Instead of producing a menthol / crosslinked PVP mixture, menthol is swollen with ethyl alcohol. By mixing with cross-linked PVP, the cross-linked PVP swells, and menthol / ethyl alcohol is mixed. A ru / crosslinked PVP mixture was prepared. The mixing ratio was the same as in Example 11.

As a result, A collection of 31 heated fragrance-generating substrates, each measuring 42.0 mm in length, 1.5 mm in width, and 0.3 mm in thickness. Combined 421 is wrapped around a paper heated fragrance generating base material wrapping member 422, which is a heated fragrance generating base material. The aroma source 420 consists of a heat-to-heat aroma-generating substrate assembly of 0.63g per heat-to-heat aroma source 420. The assembly of the heated aroma generating substrate 42 includes body 421 and is relative to the volume of the heated aroma generating source 420. The volume filling efficiency of 1 was 0.59. <Comparative Example 12>

[0182] In exactly the same manner as in Comparative Example 7, a 0.3 mm thick sheet-like heated material was produced in the first molding step. In the second molding process, the fragrance generating substrate is cut into a rectangle measuring 150 mm in length and 210 mm in width. - After being cut, a rotary cutter is used to cut it into pieces that are 210mm long, 1.5mm wide, and thick The material was cut into pieces approximately 0.3 mm thick, and a long, rectangular prismatic heating substrate for generating aroma was manufactured.

[0183] This heated fragrance-generating substrate consists of 31 strands aligned in the longitudinal direction, and is made of paper with a basis weight of 34 g / m2. By being rolled up, wrapped, and glued, a cylindrical roll with an outer diameter of 5.5 mm is produced. After being manufactured, it was cut to a length of 42.0 mm, and a heated aroma source was produced. As a result, A collection of 31 heated fragrance-generating substrates, each measuring 42.0 mm in length, 1.5 mm in width, and 0.3 mm in thickness. Combined 421 is wrapped around a paper heated fragrance generating base material wrapping member 422, which is a heated fragrance generating base material. The aroma source 420 consists of a heat-to-heat aroma-generating substrate assembly of 0.63g per heat-to-heat aroma source 420. The assembly of the heated aroma generating substrate 42 includes body 421 and is relative to the volume of the heated aroma generating source 420. The volume filling efficiency of 1 was 0.59.

[0184] To specifically confirm the cooling agent sorption capacity of cross-linked PVP, menthol was selected as the cooling agent. Using the heated aroma sources from Examples 11-18 and Comparative Examples 5-12, the following evaluation 4 was performed. We implemented steps ~6. [Rating 4-1]

[0185] Conventionally, heating-treated fragrance-generating substrates containing menthol can lead to ethides being lost when left for extended periods. The alcohol has completely evaporated, and the menthol is soluble in ethyl alcohol but sparingly soluble in water. The phenomenon of white crystals precipitation was observed. Therefore, in evaluation 4-1, menthol The white crystal precipitation test was performed as follows.

[0186] Using the heated aroma sources produced in Examples 11-15 and Comparative Examples 5-8, Evaluation 1 IQOS (registered) is a heated smoking device 100 equipped with a blade-type heat source 130 as described in -1. A heated fragrance cartridge 300 that can be attached to a (trademark) and used for smoking has been manufactured. Twenty heated fragrance cartridges (300) measure 70mm on the long side, 14mm on the short side, and 45mm in height. The heated aroma source 320 is placed in contact with the bottom of a paper box and then packed vertically into the box. It was left in a polyethylene bag at 5°C for 48 hours. Furthermore, the box was heated to remove the aroma. Remove the cartridge 300 and leave it in a room temperature and humidity environment for one day, then remove the heated fragrance generating substrate. The end face that was in contact with the bottom of the box of the combined unit 321 was observed using a magnifying glass with a magnification of 5x. The number of white menthol crystals that precipitated was counted, and the number of crystals was measured for 20 heated fragrance cartridges. The average value of 300 was calculated and evaluated according to the following criteria. Rank C indicates that the product was stored for a long period of time. Furthermore, menthol dissipates outside the heated fragrance-generating substrate, and even when the heated fragrance-generating substrate is heated, There is a high possibility that the refreshing feeling will be diminished, so it is presumed that it would be usable if it were rank B or A. . Rank A: 0 white crystals Rank B: 1-4 white crystals Rank C: 5 or more white crystals

[0187] In evaluation 4-1, the conditions for leaving the heated fragrance cartridge were as follows: This setting was determined after considering various conditions that facilitate crystal precipitation. [Rating 4-2]

[0188] The purpose is similar to that of Evaluation 4-1, but it may be affected by the shape of the heated aroma-generating substrate. Therefore, the heated aroma sources produced in Examples 16-18 and Comparative Examples 9-12 The heated smoking device 200 uses the omnidirectional heat source 240 described in Evaluation 1-2, which is a Gro A heated fragrance cartridge 400 that can be attached to (registered trademark) and used for smoking has been manufactured. And these 20 heated fragrance cartridges 400 have dimensions of 55mm on the long side, 12mm on the short side, and height The heated aroma source 420 is placed vertically in contact with the bottom of an 85mm thick cardboard box. Ta.

[0189] Afterward, it was left under the exact same conditions as in evaluation 4-1, and then, using the exact same method as in evaluation 4-1, It was evaluated according to the criteria. [Rating 5-1]

[0190] The primary purpose of evaluation 4-1 is to determine the correlation between the precipitation test and the smoking test. Using the heated fragrance cartridges that were tested, smoke them in the manner described in Evaluation 1-1. As described in Evaluation 2-1, the sensory perception of the cooling sensation of menthol was assessed by five subjects. An investigation was conducted.

[0191] The smoking test was conducted as follows: Examples 11-15 and Comparative Examples 5-8 were manufactured. Using the heated fragrance source, the heated fragrance cartridge 300 was produced in the same manner as in Evaluation 1-1. Manufactured, 20 of these heated fragrance cartridges 300 are 70mm long and 14mm short. The heated aroma source 320 is placed vertically in contact with the bottom of a 45mm high cardboard box. In this smoking test, the box containing the heated aroma cartridges was, in this manner, normally It was left under conditions similar to those a smoker would use for storage, at 25°C for two weeks. The subjects compared the cooling sensation of menthol using heated fragrance cartridges before and after exposure to air. The valuation criteria are as follows: Rank A: No change in the cooling sensation of menthol before and after leaving it to stand. Rank B: The cooling sensation of menthol is slightly reduced after leaving it to stand compared to before. Rank C: The cooling sensation of menthol is clearly reduced after leaving it to stand compared to before. [Rating 5-2]

[0192] Regarding the smoking test, in addition to the same objectives as evaluation 5-1, the shape of the heated aroma-generating substrate and the applied The configuration of the heated fragrance cartridge, and the method of the heat source for the heated smoking device and the associated heated fragrance. Since the shape of the fragrance source is likely to have an impact, it is also important to check whether or not these factors are influencing the scent. The objective was to evaluate the heated fragrance cartridges that underwent the precipitation test described in Evaluation 4-2. Smoking was performed in the manner described in 1-2, and evaluation was conducted on 5 subjects as described in 2-2. A sensory evaluation was conducted regarding the cooling sensation of menthol.

[0193] The smoking test was conducted as follows: The products manufactured in Examples 16-18 and Comparative Examples 9-12. Using the heated fragrance source, the heated fragrance cartridge 400 was evaluated in the same manner as in Evaluation 2-1. Manufactured, these 20 heated fragrance cartridges (400) measure 55mm on the long side and 12mm on the short side. The heated aroma source 420 is placed vertically in contact with the bottom of a paper box that is 85 mm high. In this smoking test, boxes containing heated aroma cartridges were used in this manner. It was left under conditions similar to those a typical smoker would use for storage, at 25°C for two weeks. The subjects compared the cooling sensation of menthol using heated fragrance cartridges before and after being left to stand. The evaluation criteria are as follows: Rank A: No change in the cooling sensation of menthol before and after leaving it to stand. Rank B: The cooling sensation of menthol is slightly reduced after leaving it to stand compared to before. Rank C: The cooling sensation of menthol is clearly reduced after leaving it to stand compared to before. [Rating 6]

[0194] Precipitation tests and smoking tests reveal the results of smoking tests by understanding their correlation. In addition to clarifying the factors involved, smoking tests are necessary for manufacturing heated fragrance cartridges. It is believed that the results of the smoking test can be determined by the precipitation test without performing any other tests. However, the precipitation test involves the deposition of ment on the edge surface of the heated aroma-generating substrate of the heated aroma-generating source. It depends on the number of white crystals in the ion and does not depend on the internal state of the heated aroma source. Therefore, in order to find criteria for more accurately determining the results of the smoking test, the menthol reduction rate We measured it.

[0195] The menthol reduction rate is measured under conditions of 17°C and 65% relative humidity, immediately after heating. When approximately 5g to 10g of the generated substrate is accurately weighed, the amount of menthol contained in the heated aroma-generating substrate is measured. Let d(0) be the mass of the heated fragrance generating substrate, and calculate it from the composition of the components that make up the substrate. The rate of decrease d is the amount of the heated aroma-generating substrate after being left at 5°C for 24 hours. Let d(24) be the mass, and d(48) be the mass after being left at 5°C for 48 hours. Then the following equation (1 ) defined. Here, the reason for subtracting d(48) from d(24) in the above formula is ment Upon closer observation of the precipitation test, white crystals were observed to precipitate after 24 hours. Therefore, to eliminate dissipative components other than menthol and better reflect the dissipation of menthol... This has significance because it allows for that. d = {(d(24) - d(48)} / d(0) (1)

[0196] The compositions of Examples 11-18 and Comparative Examples 5-12 used in Evaluations 4-6, and Table 2-1 shows the shape and number of heated fragrance generating substrates used as the heated fragrance generating source. The manufacturing conditions for the heat-generating fragrance base material composition and the results of evaluations 4 to 6 are shown in Table 2-2. [Table 2-1] [Table 2-2]

[0197] As is clear from the results in Table 2-2, the cross-sectional shape of the heated aroma-generating substrate is perpendicular to the longitudinal direction. Regardless of the physical characteristics of the heated aroma-generating substrate, such as length and number, and also regarding heated smoking Regardless of the heat source method used for the ingredients, there is good correlation between the precipitation test, smoking test, and menthol reduction rate. There is a good correlation. In particular, when the menthol reduction rate is 0.200 or less, cross-linked PVP is It can adsorb menthol and effectively prevent its dissipation over time. The ability to manufacture such a heated aroma-generating substrate is possible by heating menthol to produce an aroma. To mix with the composition of the generating substrate, menthol is dissolved in ethanol and mixed as menthol / ethanol. A method for producing a heated fragrance-generating substrate, comprising a step of mixing cross-linked PVP with a tanol solution. Only those to which this is applied. Also, the menthol content is 1 to 1 of the heated fragrance generating substrate. The amount is 10% by mass, and the cross-linked PVP content is 2-10% by mass in the heated aroma-generating substrate. Furthermore, when the amount is 1 to 6 times the amount of menthol, in particular, the time-span of menthol This can prevent data loss.

[0198] Cross-linked PVP can prevent the temporal dissipation of menthol in this way. Other cooling agents, such as menthol, as well as menthyl ether, menthyl ester, and menthol derivatives such as menthyl carbonate, as well as menthone and its derivatives, Furthermore, menthane and its derivatives, and menthanecarboxylic acid-N-ethylamide [W S3], Nα-(menthanecarbonyl)glycine ethyl ester [WS5], Menthanka Rubonic acid-N-(4-cyanophenyl)amide, menthanecarboxylic acid-N-(4-cyano Methylphenyl amide and menthanecarboxylic acid-N-(alkoxyalkyl)amide Menthane carboxylic acid amides such as , and methyl diisopropylpropionate amide [ 2,3-dimethyl-2-(2-propyl)-butyrate-N-methylamide [WS23] etc. ,3-dimethyl-2-(2-propyl)-butyric acid derivatives, and (l(-)-isoprego Isoplegol, l(-)-isoplegol acetate and its esters, N- (2-(pyridine-2-yl)ethyl)-3-p-menthanecarboxamide, (1R, 2S,5R)-N-(4-methoxyphenyl)-5-methyl-2-(1-isopropyl) Cyclohexane-carboxamide [WS12] and carboxamides such as oxamate Furthermore, it is also effective against L-carbone, xylitol, thymol, spirantol, etc. This has been confirmed.

[0199] Thirdly, by incorporating microcrystalline cellulose into the heated fragrance-generating substrate, the fragrance source material and The aerosol form is homogeneously mixed and dispersed via a binder, and is subjected to compression and shearing. Repeating this process, for example in sheet forming using a three-roll mill, the sheet aggregates It can effectively prevent breakage and adhesion to metal rolls, and the heated fragrance generating substrate In addition to reducing the volume shrinkage over time due to drying, etc., it acts as a reinforcing material for the heated fragrance-generating substrate. Due to improved strength, the heated aroma-generating substrate will not detach, fall off, or break off before and after smoking and after long-term storage. Examples 19-26, and, in order to specifically demonstrate that deformation and other issues can be prevented, Experiments were conducted for comparative examples 13-18. Example 19

[0200] Similar to Examples 11-13 and Examples 16-18, tea leaves and aerosols were used as the fragrance source. Zolforma, CMC and glucomannan as binders, menthol and as a cooling agent Xylitol and cross-linked PVP are used as sorbents for the cooling agent, but in this example, methyl We used microcrystalline cellulose instead of regular cellulose and confirmed its effectiveness. These were as follows: The mixture is then fed into a mixer in a single batch, and after 15 minutes of stirring and kneading, the heated aroma-generating base material is prepared. The composition was manufactured. 100 parts by mass of dried and ground black tea leaves Glycerin 30 parts by mass Propylene glycol 30 parts by mass 4 parts by mass of sodium carboxymethylcellulose (CMC) Glucomannan 1 part by mass Microcrystalline cellulose 15 parts by mass Cross-linked polyvinylpyrrolidone (PVP) 10 parts by mass Menthol 5 parts by mass Xylitol 1.5 parts by mass

[0201] The tea leaves are dried at 70°C until the moisture content is approximately 2% by mass, then ground, and 80 The material used was that which had passed through a mesh sieve. Furthermore, the microcrystalline cellulose had an average particle size of 90 μm. A sample with a mass-average molecular weight (Mw) of 36,000 was used. However, the average particle size was Although the particle size is 90 μm, the residue on a sieve with a mesh size of 75 μm is 5% of the total amount of microcrystalline cellulose. The amount is 2% by mass, and the residue on the sieve at a mesh opening of 250 μm is equal to the total amount of microcrystalline cellulose. The particle size distribution is narrow, at 1% by mass, and the effect of microcrystalline cellulose is clearly expressed. I chose to do that.

[0202] The composition of the heated fragrance generating substrate produced in this manner is pressed between narrow rolls. Compression caused by this process and shear due to the difference in roll speeds uniformly mix and divide the high-viscosity paste. It can be dispersed and, moreover, formed into a sheet using a three-roll mill to a predetermined thickness. A sheet-like heated aroma-generating substrate was manufactured. In this embodiment, the roll spacing was pre-adjusted. And the process of pressing the doctor blade against the rolls and forming it into a sheet, at a speed ratio between the rolls. By repeating the process eight times, a sheet-like heated aroma-generating substrate with a thickness of 0.1 mm was produced. During this time, water was supplied as needed, depending on the condition of the sheet.

[0203] This 0.1mm thick sheet-like heated fragrance generating substrate measures 150mm in length and 240mm in width. After being cut into a square, a rotary cutter was used to cut it into pieces 240mm long, 1.5mm wide, and thick. A long, rectangular prismatic heating substrate with a thickness of 0.1 mm was manufactured to generate aroma.

[0204] The 150 long, rectangular prismatic heating substrates produced in this manner are aligned in the longitudinal direction. Furthermore, paper with a basis weight of 34 g / m2 is used as the heating-to-heat aroma-generating substrate wrapping member 322. By being rolled up and glued together, a cylindrical roll with an outer diameter of 6.9 mm was produced. Then, it was cut to a length of 12.0 mm to produce a heated aroma source. A collection of 150 heated fragrance-generating substrates, each measuring 0.0 mm in diameter, 1.5 mm in width, and 0.1 mm in thickness. 21 is a heated fragrance generating source 3 wrapped around a paper heated fragrance generating base material wrapping member 322. 20 is a heated aroma-generating substrate assembly 32 of 0.29g per heated aroma-generating source 320. The volume of the heated aroma generating substrate assembly 321 relative to the volume of the heated aroma generating source 320 includes 1. The packing density was 0.60. In addition, the heated fragrance generating substrate 3211 (Figure 3) contains a fragrance source. For every 100 parts by mass of the material, 60 parts by mass of aerosol former, and CMC and GL are used as binders. The amounts are 4 parts by mass and 1 part by mass of rucomannan, and 15 parts by mass of microcrystalline cellulose. Bridged PVP is 10 parts by mass, and menthol and xylitol are each 5 parts by mass. It contains 1.5 parts by mass. Example 20

[0205] Example 20 shows the effect of microcrystalline cellulose on a cross section perpendicular to the longitudinal direction of the heated aroma-generating substrate. To specifically demonstrate that it is independent of the surface shape, the heated aroma-generating substrate is compared with Example 19. The thickness was increased. Therefore, the heated aroma generating substrate was manufactured in exactly the same manner as in Example 19. Using the composition, a three-roll mill that repeatedly compresses and shears the material is used to process the material into a sheet-like form. A thermal fragrance generating substrate was manufactured, but in Example 20, the position of the doctor blade, the roll spacing, Furthermore, a three-roll mill with different adjustments to the inter-roll speed ratio, etc., compared to Example 19. This process was repeated eight times, and the resulting sheet-like heated aroma-generating substrate was formed with a thickness of 0.3 mm.

[0206] This 0.3mm thick sheet-like heated fragrance generating substrate measures 150mm in length and 240mm in width. After being cut into a square, a rotary cutter was used to cut it into pieces 240mm long, 1.5mm wide, and thick. A long, rectangular prismatic heating substrate with a thickness of 0.3 mm was manufactured to generate aroma.

[0207] The 50 long, rectangular prismatic heating substrates produced in this manner are aligned in the longitudinal direction. Furthermore, paper with a basis weight of 34 g / m2 is used as the heating-to-heat aroma-generating substrate wrapping member 322. After being rolled up and glued, a cylindrical roll with an outer diameter of 6.9 mm is produced. It was then cut to a length of 12.0 mm to produce a heated aroma source. As a result, the length was 12. Fifty heated aroma-generating substrate aggregates 321, each measuring 0 mm in width, 1.5 mm in height, and 0.3 mm in thickness. The heated fragrance generating source 320 is wrapped around a paper heated fragrance generating base material wrapping member 322. Each heated aroma source 320 contains 0.29g of heated aroma generating substrate assembly 321. Including the volume of the heated aroma generating substrate assembly 321 relative to the volume of the heated aroma generating source 320 The filling ratio was 0.60. Also, the composition contained in the heated fragrance generating substrate 3211 (Figure 3) This is the same as in Example 19. Example 21

[0208] In Example 21, the effect of microcrystalline cellulose was observed in the cross section perpendicular to the longitudinal direction of the heated aroma-generating substrate. To specifically demonstrate that it is shape-independent, the heated aroma-generating substrate is even more precise than in Example 20. The thickness was increased. Therefore, the heated aroma-generating substrate was manufactured in exactly the same way as in Example 29. Using the composition, a three-roll mill is used to repeatedly compress and shear the material, and then the sheet-like material is heated. Although a fragrance generating substrate was manufactured, in Example 21, the position of the doctor blade and the distance between the rolls were further considered. Three rolls with different adjustments to spacing and inter-roll speed ratio than in Example 20. The milling process was repeated eight times to form a sheet-like heated aroma-generating substrate with a thickness of 0.5 mm.

[0209] This 0.5mm thick sheet-like heated fragrance generating substrate has dimensions of 150mm in length and 240mm in width. After being cut into a square, a rotary cutter was used to cut it into pieces 240mm long, 1.5mm wide, and thick. A long, rectangular prismatic heating substrate with a thickness of 0.5 mm was manufactured to generate aroma.

[0210] The 30 long, rectangular prismatic heating substrates used to generate aroma, manufactured in this manner, are aligned in the longitudinal direction. Furthermore, paper with a basis weight of 34 g / m2 is used as the heating-to-heat aroma-generating substrate wrapping member 322. After being rolled up and glued, a cylindrical roll with an outer diameter of 6.9 mm is produced. It was then cut to a length of 12.0 mm, and the heated aroma source 320 was manufactured. As a result, the length A collection of 30 heated fragrance-generating substrates, each measuring 12.0 mm in diameter, 1.5 mm in width, and 0.5 mm in thickness. 321 is a heated fragrance generating source wrapped around a paper heated fragrance generating base material wrapping member 322. 320 is a heated aroma-generating substrate assembly 3 of 0.29g per heated aroma-generating source 320.

Also, the heated aroma generating substrate 3211 (Figure 3) contains The composition is the same as in Example 19. Example 22

[0211] To investigate the effect of microcrystalline cellulose content, as an example, we will examine the effects of microcrystalline cellulose. The amount of - is 4 parts by mass relative to the tea leaves, which are the aromatic material, and is exactly the same as in Example 20. A heated aroma source was manufactured. The result was a device with a length of 12.0 mm, a width of 1.5 mm, and a thickness of 0 mm. Fifty heated fragrance generating substrate aggregates 321, each 3 mm in diameter, are wrapped in a paper-based heated fragrance generating substrate.

[0216] Examples 19-22 and Comparative Examples 13-16 described above were shown in the smoking test described later, Molding process for evaluation of blade-type heat sources using IQOS® by a motor. However, depending on the heat source, the heating method, the maximum temperature reached, and the source of the heated aroma, We believe that differences in the configuration of the heated fragrance cartridges may affect the evaluation results. Therefore, although it is the same heated smoking device, the Glo (Registered) uses electromagnetic induction heating as an omnidirectional heat source. Evaluations were also conducted using registered trademarks. Examples 23-26 and Comparative Examples 17 and 18 were used. The composition of the heated aroma-generating substrate and its cross-sectional shape perpendicular to its longitudinal direction are as shown in Examples 19-22, and This corresponds to Comparative Examples 14 and 16, but is compatible with heated aroma generation corresponding to Glo®.

[0229] Using the heated aroma sources produced in Examples 19-26 and Comparative Examples 13-18, micro-compounding was performed. The following evaluations 7-11 can be performed to specifically demonstrate the effects of crystalline cellulose. did. [Rating 7]

[0230] The heated aroma source 320 of Examples 19-22 and Comparative Examples 13-16 was used for evaluation. As described in 1-1 and Figure 1, it is attached to a heated smoking device 100 equipped with a blade-type heat source. A heated aroma cartridge 300 is manufactured for smoking, and after one smoking session, the heated smoking process is carried out. Remove the heated fragrance cartridge 300 from the component 100, and remove the heated fragrance generating base material 3211( A drop test was conducted as shown in Figure 3).

[0231] The drop test involves dropping the heated fragrance cartridge 300, which has been heated after smoking, vertically from the heated fragrance source 320. By shaking it up and down three times in that direction, the heated aroma source 320 is created from paper heated aroma The heated fragrance generating substrate 3211 (Figure 3) is wrapped with a fragrance generating substrate wrapping member 322. We observed whether or not the parts had fallen off. The evaluation criteria were as follows: Rank A: No elimination or dropping. Rank B: Dropped or eliminated. [Rating 8]

[0232] Similar to Evaluation 7, the heated aroma source 320 of Examples 19-22 and Comparative Examples 13-16 Using this, as described in Evaluation 1-1 and Figure 1, a heated smoking device 1 equipped with a blade-type heat source was constructed. We manufactured a heated fragrance cartridge 300 that is attached to the 00 and used for smoking.

[0233] These 20 heated fragrance cartridges (300) measure 70mm on the long side, 14mm on the short side, and 45mm in height. After the heated aroma source 320 is placed vertically in contact with the bottom of a paper box that is mm in size, It was left at 45°C for two weeks. After that, the heated fragrance cartridge 300 was removed from the box. Shake the heated fragrance cartridge 300 vertically downwards and up and down three times. As a result, the heated aroma source 320 is a paper-based heated aroma generating substrate wrapping member. Observe whether the heated fragrance generating substrate 3211 (Figure 3), which is wound around 322, has fallen off or dropped. I understand. The evaluation criteria are as follows: Rank A: No elimination or dropping. Rank B: Dropped or eliminated. [Rating 9]

[0234] The heated aroma source 420 of Examples 23-26 and Comparative Examples 17 and 18 was evaluated. As shown in Value 1-2 and Figure 2, it is attached to a heated smoking device 200 equipped with an omnidirectional heat source. After manufacturing the heated fragrance cartridge 400 for smoking, this heated fragrance cartridge 4 20 pieces of 00 are placed at the bottom of a cardboard box measuring 55mm on the long side, 12mm on the short side, and 85mm in height. After being placed in a box vertically with the heated aroma source 420 in contact with it, it was left at 45°C for two weeks.

[0235] From the box that had been left like this, remove the heated fragrance cartridge 400 as shown in Figure 2. After attaching the heated fragrance cartridge 400 to the heated smoking device 200 and smoking, remove it. The detachment process involves a series of operations to evaluate the operability of the heated fragrance cartridge 400. The test was conducted. The evaluation criteria are as follows: Rank A: No deformation of the heated fragrance cartridge or detachment of the heated fragrance generating substrate during attachment or detachment. Rank B: Deformation of the heated fragrance cartridge and detachment of the heated fragrance generating substrate occurred during attachment / detachment. [Rating 10]

[0236] Similar to evaluation 9, the 400 heated fragrance cartridges were boxed and left at 45°C for two weeks. Afterwards, remove the heated fragrance cartridge 400 from the box and position the heated fragrance source 420 vertically. By shaking it up and down three times downwards, the heated aroma source 420 is created from paper heated aroma The heating fragrance generating substrate wrapped in the fragrance generating substrate wrapping member 422 may fall off or drop. We observed whether or not it was present. The evaluation criteria were as follows: Rank A: No elimination or dropping. Rank B: Dropped or eliminated. [Rating 11-1]

[0237] The factors that result in a rating of 7-10 are thought to be as follows: fragrance source material and aerosol. The former is mixed and dispersed via a binder, allowing for sheet formation by compression and shearing. For example, in the production of sheets of heated aroma-generating substrates using a three-roll mill, microcrystals When cellulose is added, the cohesive breakdown of the sheet and adhesion to the metal roll are effectively prevented. Because the mixture is stopped and homogeneous mixing and dispersion occur, a high-density heated aroma-generating substrate is produced. It is thought that microcrystalline cellulose does not absorb solvents such as water or ethanol. Since the cellulose is in powder form and present within the heated aroma-generating substrate, microcrystalline cellulose acts as a reinforcing material. It is believed that this action will produce a heated aroma-generating substrate with excellent strength. A heating-to-aroma-generating substrate containing microcrystalline cellulose, such as the above, has a volume yield over time due to drying, etc. It is presumed that the contraction will be reduced.

[0238] Therefore, the shape of the heated fragrance generating substrate due to volume shrinkage caused by heating and drying of the heated fragrance generating substrate. The rate of change was measured, and its correlation with evaluations 7-10 was examined. The specific method for determining the rate of change is as follows: Examples 20 and 22, and Comparative Example 14 and A sheet-like heated aroma-generating substrate with a thickness of 0.3 mm, manufactured in step 16, is given a length of 50 mm. A test piece used to measure the volume shrinkage of a rectangular prismatic heating substrate that generates fragrance, cut into a rectangle with a width of 15 mm. The heating and drying process was performed using a halogen moisture meter (electronic halogen moisture meter) (Bangxi In Manufactured by Strument Technology Co. Ltd., Model number: DHS-50- Using 5), place the test specimen on the sample dish of the halogen moisture meter, and the halogen placed inside the cover The test specimen was heated from above the sample dish using a lamp. The heating temperature was 105°C, and during drying... The length, width, and thickness of the test specimen were measured at 0 minutes, 10 minutes, and 15 minutes. Using the measured values, and from the definition formula for the rate of change shown in Table 4-1, the length is 50 mm, the width is 15 mm, and the thickness is... Length change rate La (%), width change rate Wa (%), width of a 0.3 mm thick test specimen after 10 minutes of drying. The rate of change Wa (%), the rate of change in thickness Ta (%), and the length 50 mm, width 15 mm, Length change rate Lb(%) and width change rate Wb(%) after drying for 15 minutes of a 0.3 mm thick test specimen. The width change rate Wb (%) and the thickness change rate Tb (%) were calculated. Here, the drying time was 0 minutes. The length, width, and thickness of the test specimen were measured at a temperature of 28°C to 30°C and a relative humidity of approximately 40% RH. Measurement when the moisture content is 15-20% by mass, adjusted by storage in a controlled atmosphere. Values ​​were used. [Rating 11-2]

[0239] Although the purpose is the same as in Evaluation 11-1, the specific surface area differs depending on the shape of the test specimen, and volume yield Since it may affect shrinkage, test specimens are used to examine the correlation between evaluations 7-10 and volume shrinkage. The shape dependence was investigated. That is, similar to Evaluation 1-1, Examples 20 and 22, and In Comparative Examples 14 and 16, a 0.3 mm thick sheet-like heated aroma-generating substrate was produced. It uses a rectangular prismatic heated aroma generator cut into a rectangle 12 mm long and 1.5 mm wide. The material was used as a test specimen for measuring volume shrinkage.

[0240] The measurement method was carried out in exactly the same way as in evaluation 1-1, and the length was determined from the definition formula of the rate of change shown in Table 5-1. Length change rate La(%) after drying for 10 minutes of a test specimen measuring 12 mm in length, 1.5 mm in width, and 0.3 mm in thickness. ), width change rate Wa (%), width change rate Wa (%), and thickness change rate Ta (%), and, The rate of change in length Lb( ) after drying for 15 minutes of a test specimen measuring 50 mm in length, 15 mm in width, and 0.3 mm in thickness. The percentage change in width (%), the percentage change in width (Wb), and the percentage change in thickness (Tb) are calculated. Here too, the length, width, and thickness of the test specimen with a drying time of 0 minutes were measured at a temperature of 28°C to 30°C. Then, by storing it in an atmosphere with a relative humidity of approximately 40% RH, the moisture content was adjusted to 15%. This measurement is for a concentration of approximately 20% by mass.

[0241] The compositions of Examples 19-26 and Comparative Examples 13-18 used in Evaluations 7-11 are as follows: Furthermore, the shape and number of heated fragrance generating substrates used as the heated fragrance generating source are shown in Table 3-1. Furthermore, the results for evaluations 7-11 are shown in Table 3-2. In addition, the definitions in Tables 4-1 and 5-1 are provided. Tables 4-2 and 5-2 show the calculated values ​​of the rate of shape change due to volume contraction of the heated fragrance-generating substrate. .

[0242] The results of the drop tests and attachment / detachment tests shown in Table 3-2 for Examples 19-22 and Comparative Example 14 As is clear from the comparison with ~16, and from the comparison between Examples 23~26 and Comparative Examples 17 and 18. Regardless of the cross-sectional shape perpendicular to the longitudinal direction of the heated aroma-generating substrate, microcrystalline cellulose A heated fragrance source manufactured using a heated fragrance generating substrate containing a heated fragrance source Even when exposed to drying over time and heat drying due to smoking, the cartridge will not shrink in volume. This resolved the problem of the heated fragrance-generating substrate falling off or dropping. The problem lies in the difference between a blade-type heat source using a heater and an omnidirectional heat source using electromagnetic induction heating. The heating method, the maximum temperature reached, and the structure of the heated fragrance source and the heated fragrance cartridge. Regardless of the composition, the problem was solved by adding microcrystalline cellulose. [Table 3-1] [Table 3-2]

[0243] The effect of this microcrystalline cellulose was observed in a test specimen measuring 50 mm in length, 15 mm in width, and 0.3 mm in thickness. As can be seen in Table 4-2, which shows the rate of shape change, the material containing 2% by mass of microcrystalline cellulose Length change rate La = 7.2% and width change rate Wa = 5.7% after 10 minutes of drying of heated fragrance generating substrate. , and a thickness change rate Ta = 1.2%, and a length change rate Lb = 8.1% after drying for 15 minutes. At least one of the following: a width change rate Wb = 6.1%, and a thickness change rate Tb = 1.5%. These can be used as thresholds, and it is not necessary to satisfy all of these thresholds simultaneously. And, Table 3-2 As shown, if this shape change rate is satisfied, there is a good correlation with the results of each drop test and attachment / detachment test. The property can be obtained. Thus, it is sufficient to satisfy any one of the length, width, and thickness. Although not clearly visible in Table 4-2, the area of ​​the cross-section perpendicular to the longitudinal direction is even smaller. When the heat-generating fragrance substrate is dried, it becomes distorted, and plant stems and leaves are dispersed as fragrance sources. This is because the heated aroma-generating substrate is anisotropic. [Table 4-1] [Table 4-2]

[0244] This correlation is related to the shape change in a test specimen measuring 12 mm in length, 1.5 mm in width, and 0.3 mm in thickness. Table 5-2, which shows the percentages, is for heated aroma-generating substrates containing 2% by mass of microcrystalline cellulose. After drying for 10 minutes, the change in length La' = 4.8%, the change in width Wa' = 5.0%, and the thickness The rate of change Ta' = 1.2%, and the rate of change in length Lb' = 5.8% after 15 minutes of drying, and the rate of change in width At least one of the following is set as the threshold: Wb' = 5.1% and thickness change rate Tb' = 1.5% This is sufficient, and it is not necessary to satisfy all of these thresholds simultaneously. In this case as well, see Table 3-2. As shown, if this shape change rate is satisfied, there is a good correlation with the results of each drop test and attachment / detachment test. You can obtain this. [Table 5-1] [Table 5-2]

[0245] Thus, the heated fragrance generating substrate of the present invention comprises a fragrance source material, an aerosol former, and a bond Although it consists of materials with different properties such as mixtures, the type of additive and the method of adding them, Furthermore, the manufacturing method including curing of the composition, the addition of cross-linked PVP and the method of adding it, and microcrystals The addition of cellulose creates a homogeneous mixture of fragrance source material, aerosol former, and binder. This allows for mixing and dispersion, easily preventing the dissipation of fragrance over time, as well as preventing the shrinkage of the shape over time. Furthermore, to provide a high-quality heating-sensitive aroma-generating substrate that prevents shrinkage of shape due to heating. That is the case.

[0246] As a result, a heated aroma source equipped with the heated aroma generating substrate of the present invention When attaching or detaching a cartridge to a heated smoking device, deformation of the heated aroma source and the generation of heated aroma. This solves problems such as the detachment and dropping of the base material, and provides the necessary toughness and strength for this molding process. Along with this, the heated fragrance generating substrate allows you to fully enjoy the fragrance released from the heated fragrance source material. It can be provided.

[0247] Furthermore, the heated fragrance generating substrate of the present invention uses menthol, xylitol, and other cooling agents as fragrances. When a cooling agent is added, the time-dependent dissipation of fragrances and cooling agents is suppressed, and the heated fragrance containing them is also suppressed. Even after storing a heated fragrance cartridge equipped with a fragrance source for a long period of time, it can still be attached to a heated smoking device. When smoking, you can fully enjoy the aroma of the heated aroma-generating substrate.

[0248] Furthermore, the heated aroma-generating substrate of the present invention exhibits minimal dimensional change due to drying, and the heated substrate containing it After smoking with a heated fragrance cartridge equipped with a fragrance source attached to a heated smoking device, the odor... Even if heated, the heated fragrance generating substrate will not detach or fall from the heated fragrance cartridge, and will remain intact for a long period of time. Even after installation, the heated fragrance generating substrate does not detach or fall from the heated fragrance cartridge. A heated aroma generator that is easy to handle and prevents contamination of the heat source of heated smoking devices. We can provide the materials.

[0249] The present invention further relates to a heated aroma generating source using such a heated aroma generating substrate, and the heated The purpose is to provide a heated fragrance cartridge equipped with a fragrance source, therefore, As will be explained in detail using the figures, the heated aroma source and heated aroma cartridge of the present invention The invention is not limited to these, and various modifications may be made without departing from the spirit of the present invention. It is possible to implement it, and is limited only to the technical concept described in the claims. It is.

[0250] Figure 1 shows the coating used in the above examples and comparative examples, suitable for a blade-type heat source using a heater. An example of a heated fragrance cartridge 300 is shown. The heated fragrance according to this embodiment of the present invention. The fragrance cartridge 300 is an assembly 321 of the heated fragrance generating base material 3211 (Figure 3) of the present invention. A heated fragrance generating source 320 is wrapped around a heated fragrance generating base material wrapping member 322, and A support member 331 is attached to one end of the longitudinal suction side of the heated aroma source 320, and A filter member 333 attached to one end of the support member 331 on the longitudinal suction side is With the heated fragrance cartridge wrapped around the outer casing member 310, the support member 331 and the phi The mouthpiece 330, which consists of a filter member 333, has a mouthpiece around the filter member 333. It is wrapped with splice reinforcement member 3301.

[0251] Figure 2 shows the materials used in the above examples and comparative examples, suitable for an omnidirectional heat source using electromagnetic induction heating. An example of a heated fragrance cartridge 400 is shown. The heated object according to this embodiment of the present invention. The fragrance cartridge 400 is an assembly 421 of the heated fragrance generating substrate of the present invention that generates fragrance when heated. A heated fragrance source 420 wrapped around a raw material wrapping member 422, and this heated fragrance A cooling member 432 is attached to one end of the suction side in the longitudinal direction of the energy source 420, and this cooling member 43 A filter member 433 attached to one end of the suction side in the longitudinal direction of 2, and this filter member A hollow tube 434 attached to one end of the longitudinal suction side of 433 is connected to the heated aroma cartridge. It is wrapped with exterior material 410.

[0252] However, the heated fragrance cartridge of the present invention is not limited to this configuration. This allows for a variety of configurations to suit smokers' preferences regarding flavor, smoke, inhalation volume, and cost. Its distinguishing feature is that it allows for this.

[0253] This diverse configuration uses a heated fragrance cartridge 300 suitable for the blade-type heat source shown in Figure 1. As will be explained, the heated fragrance cartridge of the present invention is not limited to these. and is limited only to the technical concept described in the claims.

[0254] First, the heated fragrance source 320 that constitutes the heated fragrance cartridge 300 of the present invention is shown in Figure As shown in 1, the aggregate 321 of the heated fragrance generating substrate 3211 (Figure 3) generates fragrance when heated. It is characterized by being wound around a base material wrapping member 322. Figure 3 shows the heated aroma generator. As is clear from the cross-sectional view perpendicular to the longitudinal direction of the source, the heated aroma-generating substrate assembly of the present invention 321 is a prismatic heated fragrance generating substrate (single unit) 3211 and this heated fragrance generating substrate 3 It consists of a heated aroma-generating substrate primary aggregate 3212 formed by irregular contact between 211 and other elements. , inside such heated fragrance generating substrate assembly 321, and heated fragrance generating substrate assembly 3 Between 21 and the heated aroma-generating substrate wrapping member 322, there is a primary condensate internal gas flow path 321 A, Gas channel 321B between primary aggregates, Substrate only / Gas channel 321C between primary aggregates, Substrate collection A heated fragrance generating substrate that facilitates the formation of gas flow paths 321D between combined / wrapping members, etc. It is characterized by a cross-sectional shape of 3211 and an arrangement parallel to the longitudinal direction.

[0255] However, the cross-sectional shape of the heated aroma-generating substrate is a rectangle as shown in Figure 3, which is important for productivity and air quality. While preferable for achieving both gas flow path formation and other desirable features, the shape of the gas flow path is typically a polygon or star polygon. From the standpoint of formation, it is more preferable. Furthermore, it is even more preferable if the heated aroma-generating substrate is hollow. preferable.

[0256] Furthermore, it does not necessarily have to be in the shape of a rectangular prism; it may also be in the shape of a sheet, in which case the heating... It is preferable for the formation of a gas flow path that the aroma source is irregularly folded parallel to its longitudinal direction. .

[0257] Furthermore, as will be described later, the heated aroma source is not necessarily the heated aroma-generating substrate wrapping section. It does not require any material; for example, the heated fragrance cartridge outer component 3 in Figure 4 It may be wrapped directly around the outer casing member corresponding to 10. In this case, the outer casing member may be heated. When constructing the cartridge, it is preferable to use a material that has sufficient strength.

[0258] Furthermore, the heated fragrance wrapping material does not necessarily have to be paper. Since there is no contact and the heating-to-aroma-generating substrate needs to be resistant to aerosols, Plastic film is more suitable than paper, especially in terms of environmental protection, as it is biodegradable. It is preferable to use a plastic film. The plastic should be a polyolefin. Polyester, nylon and other plastics and engineering plastics, etc. Examples of biodegradable plastics include poly(3-hydroxybutyrate) (PHB) and poly(ε- Caprolactone (PCL), Poly(butylene succinate) (PBS), Poly(L-L) Examples include copper(PLA), etc. These materials are used for heating aromatic chemicals, as described later. Cartridge exterior member 310, support member 331, cooling member 332, filter member 333 It can also be applied to the filter wrapping member 3331 and the hollow tube 334, Each material needs to be molded into a shape that exhibits the appropriate function for its intended use.

[0259] The heated fragrance cartridge 300 shown in Figure 1, according to one embodiment of the present invention, is a heated fragrance source 3 20 and a support member 3 attached to one end of the longitudinal suction side of the heated aroma source 320. 31 and a filter member 33 attached to one end of the support member 331 on the longitudinal suction side. It consists of 3 and is wound around the heated fragrance cartridge outer casing member 310, Furthermore, the filter of the mouthpiece 330, which consists of a support member 331 and a filter member 333 -The mouthpiece is wrapped around the part of component 333 with mouthpiece reinforcing member 3301. However, The spiece reinforcing member 3301 is not necessarily required, but at a minimum, the heated aroma cartridge Any exterior member equivalent to the exterior member 310 is sufficient. In other words, the essential component is the coating Excluding the heat-generating aroma source, Figure 4 primarily prevents the movement of the heated aroma source toward the suction side. A support member 331 has the function of cooling the volatile aerosol former and turning it into smoke. A cooling member 332 having the function of promoting the generation of aerosols, mainly heated to generate aroma A filter section that has the function of filtering out volatile components generated from the source and components that cause off-flavors from the smoke. A minimum of the following are selected from material 333 and hollow tube 334 which primarily has the function of being easy to hold in the mouth. It is sufficient to have one or more of each. And, as shown in Figure 4, the support member 331, cooling unit From at least one selected from material 332, filter member 333, and hollow tube 334 A mouthpiece 330 is formed. However, if two or more of these are deployed as a mouthpiece... In such cases, there is a rule that the support parts are arranged on the longitudinal suction side from the heated aroma source, The positional relationship between material 331, cooling member 332, filter member 333, and hollow tube 334 must be observed. It is preferable that this be done.

[0260] For example, the heated fragrance cartridge 300 according to one embodiment of the present invention is as shown in Figure 5. The heated fragrance generating substrate assembly 321 is wrapped with the heated fragrance generating substrate wrapping member 322. The heated aroma source 320 has water resistance and pressure resistance so that it can maintain its shape even when held in the lips. It is characterized by being fixed to one end of the outer casing member 310 of the heated fragrance cartridge. A simple structure consisting only of a heated fragrance source 320 and a heated fragrance cartridge outer casing member 310. It is one of the heated fragrance cartridges in the structure. In this case, other than the heated fragrance source 320. The heated fragrance cartridge outer component 310 in that section acts as a mouthpiece 330. It is a hollow tube 334.

[0261] The simplest heated fragrance cartridge is the heated fragrance generation source 320 shown in Figure 5. Although the base material wrapping member 322 is not provided, the heated aroma-generating base material wrapping The heated fragrance source 320, which is wrapped with the winding member 322, is more effective than the heated fragrance cartridge.

Alternatively, the heated aroma source 320 and the filter member 333 may be, The heated aroma generating base material wrapping member 322 and the filter wrapping member 3331 are wound together. It does not have to be included. Also, the support member 331, cooling member 332, filter member 333, And, after the hollow tube 334 is wrapped together with the mouthpiece wrapping member, the support member After one end of 331 and one end of the heated aroma source 320 are brought into contact, the entire assembly is heated The fragrance cartridge may be wrapped with the fragrance cartridge wrapping member 310. In addition, various other materials can be selected. A variety of heated fragrance cartridges can be manufactured depending on the construction method.

[0267] The above is a heated tobacco product used in heated smoking devices equipped with a blade-type heat source using a heater. We have described the heated fragrance cartridge of the present invention by focusing on the fragrance cartridge 300. However, these are used when attached to heated smoking devices equipped with an omnidirectional heat source using electromagnetic induction heating. This technology is applicable to the heated fragrance cartridge 400. However, it is equipped with an omnidirectional heat source. The heated fragrance cartridge 400, which is used by being attached to a heated smoking device, emits a heated fragrance. Since the entire source 320 is heated to approximately 240°C, the heated aroma-generating substrate wrapping member and As a paper substitute material for the outer casing of the heated fragrance cartridge, plastic, engineered metal, Plastics and biodegradable plastics cannot be used. (Approximately 300°C) Glass transition or thermal decomposition is initiated, resulting in heat resistance equivalent to that of cellulose fibers (which make up paper). In other words, special engineering plastics having a glass transition temperature of 240°C or higher are applied. It is necessary to do so. Examples of such special engineering plastics include polyamide. Examples include polyamides, polyarylates, polyimides, polytriazines, and liquid crystal polymers. Cut.
