Description

[Technical field]

[0001] The present invention relates to an aroma cartridge that is attached to a chamber equipped with an electrically controlled heating element of a heated smoking device so as to come into contact with the heating element, allowing the user to enjoy the aerosol smoke and aromatic components generated by heating the heating element. [Background technology]

[0002] In recent years, as smoking separation and smoking bans have become widespread in places where people gather, such as workplaces and restaurants, the number of smokers who inhale smoke from tobacco burned by flames, such as with paper cigarettes, has decreased, while the number of smokers who use electronic cigarettes, which are heated smoking devices that inhale smoke generated by heat transmitted by an electrically controlled heating element such as a heater, has rapidly increased. The reason for this is that with conventional flame-type smoking, smokers and non-smokers around them inhale harmful substances generated by the pyrolysis and combustion (600°C or higher) of tobacco materials and paper, whereas with electronic cigarettes, smokers inhale the smoke and aroma of harmless glycerin made from tobacco materials and aerosol formers at low temperatures (200-350°C) that do not result in the pyrolysis and combustion of tobacco materials, allowing them to enjoy smoking and reducing the impact on non-smokers around them.

[0003] Such electronic cigarettes can be broadly categorized into two types (Non-Patent Documents 1 and 2). One type is the capsule-type electronic cigarette and stick-type electronic cigarette, which heat a capsule or stick containing tobacco leaves and inhale smoke, etc. The other type is the liquid-type electronic cigarette, which heats a scented or flavored liquid to generate vapor and inhale it.

[0004] In particular, stick-type electronic cigarettes are highly similar to conventional cigarettes in terms of shape, smoking method, and taste, and because they inhale less harmful substances than cigarettes, stick-type electronic cigarettes have many enthusiasts and have been developed in various ways (e.g., Patent Documents 1 to 3). Specifically, an electronic cigarette is smoked by attaching a stick (electronic cigarette cartridge) to a heated smoking tool, which is an aerosol former processed into a stick shape like a cigarette with an aerosol former that generates aerosol that becomes smoke together with tobacco components, flavorings, binders, etc., and equipped with a mouthpiece. The mechanism of smoking is that when the aerosol former is attached so as to come into contact with the heat source of the heated smoking tool and heated, volatiles including the aerosol former are released from the aerosol former, and at the same time, these volatiles are sucked into the mouthpiece at the other end together with air by the smoker's inhalation, and in the process of transporting these volatiles, the volatiles of the aerosol former cool and condense to form a smoke-like aerosol, and other volatiles impart an aroma to the smoker's mouth and nose, resulting in the enjoyment of smoking (Patent Document 2). According to this mechanism, in the case of heated smoking such as stick-type electronic cigarettes, smoking can be performed at about 200 to 250°C, which is a temperature at which the aerosol former such as glycerin or propylene glycol contained in the aerosol former can be volatilized, that is, at a temperature at which the thermal decomposition of tobacco leaves begins. Therefore, compared to flame-type smoking, which burns at a temperature of at least 600°C required for combustion and even exceeds 900°C during smoking, the generation of harmful substances, which are said to be generated in large amounts as the temperature rises, is suppressed, and there is little adverse effect on health.

[0005] Also, unlike stick-type electronic cigarettes, liquid-type electronic cigarettes do not contain tobacco ingredients, and are a new smoking device that allows users to enjoy a variety of flavors, such as beverages such as coffee, cola, and Red Bull, desserts such as chocolate, vanilla, and cream, fruits such as orange, lemon, and melon, and refreshing agents such as menthol, mint, and herbs (Non-Patent Document 2). Specifically, it is an electronic cigarette that heats a liquid containing propylene glycol and vegetable glycerin mixed with flavorings and inhales the evaporated volatiles. Its greatest feature is that it contains no harmful substances, does not produce tar or nicotine, and allows users to enjoy a wide variety of flavors, and in fact, a wide variety of liquids are on the market.

[0006] Furthermore, in recent years, attempts have been made to combine the features of these two electronic cigarettes (Patent Document 4). As mentioned above, the aerosol former processed into a stick shape to be heated in conventional stick-type electronic cigarettes contains tobacco components, which causes the generation of harmful substances, tar and nicotine, even if in small amounts. Therefore, Patent Document 4 invents a stick-type electronic cigarette that does not contain tobacco components, which has been a problem with stick-type electronic cigarettes. In other words, instead of tobacco components, it is a stick-type electronic cigarette that uses an aerosol former containing an aerosol former, a binder, etc., and adopts a non-tobacco material that generates only an aroma that has the effect of promoting the comfort of the mind and body and the health and beauty of smoking.

[0007] However, stick-type electronic cigarettes that use only such non-tobacco materials are unable to use tobacco materials containing large amounts of fiber in their aerosol formers, and also have problems due to the need to use a wide variety of non-tobacco materials in order to release a variety of flavors.

[0008] First, in an aerosol-forming body containing tobacco material, the fibers of the tobacco material maintain their clumped state, preventing the tobacco material from falling off and fusing, but when a non-tobacco material that does not contain a large amount of fibers is used, a large amount of binder or the like that performs the function of fibers is used in order to stably maintain the clumped state of the heated aroma-generating sheet or heated aroma-generating filler (hereinafter referred to as the "heated aroma-generating substrate") For this reason, when the amount of binder increases, the density of the heated aroma-generating substrate increases, and the flow path (hereinafter referred to as the "gas flow path") of the volatile components (hereinafter referred to as the "gas") released by heating from the aerosol former and the heated aroma-generating substrate of the non-tobacco material is closed, making it difficult to inhale the smoke of the aerosol and the aroma components of the non-tobacco material (hereinafter referred to as the "inhaled components"), resulting in a decrease in the amount of inhalation.

[0009] In addition, since the aerosol former is made of glycerin, propylene glycol, etc., which are liquid at room temperature, the more the binder, the more it bleeds out from the heated aroma-generating substrate over time, and the heated aroma-generating substrates fuse together. This closes the gas flow path, making it difficult to suck in the components, and as a result, the amount of suction decreases. In addition, when such fusion occurs, not only does it become difficult to insert the heating element into the heated aroma-generating substrate, but it may also damage the heating element. Specifically, the heated aroma-generating substrate sticks and hardens during transportation or storage in a warehouse or storefront, making it difficult for the heating element to penetrate, which may lead to damage to the cartridge or the heating element.

[0010] Conversely, if the amount of binder, etc. added is reduced and a gas flow path is ensured, non-tobacco materials may fall off or dust may be generated, making it difficult to firmly maintain the shape of the cartridge, and the cartridge may break when inserted into the heating element. These may also be inhaled into the oral cavity.

[0011] That is, since it is necessary to maintain the generation of aerosols that become smoke and the generation of aroma components released from non-tobacco materials, it is difficult to solve the problem by significantly changing the composition or blending ratio that constitutes the heated aroma-generating substrate. Therefore, it is considered that a solution focusing on the structure of the mouthpiece, which has a significant effect on the amount of inhalation, and the manufacturing method and filling state of the heated aroma-generating substrate are required.

[0014] As described above, the present invention aims to solve the problem of reduced suction power that is specific to the use of only non-tobacco materials, without any tobacco components whatsoever, i.e., the problem of reduced amount of suction components due to blockage of the gas flow path within and between heated aroma-generating substrates, and to provide an aroma cartridge that does not cause non-tobacco materials to fall off or generate dust.

[0015] Although the term "aromatic cartridge" is used here, it may also be called a "smoking cartridge" or an "electronic cigarette compatible cartridge."

[0016] The term also applies to products that use non-tobacco materials that do not contain tobacco components as a source of flavor.

[0017] "Aroma" means "a good smell" and includes the smell that wafts from the material itself (fragrance), the smell that fills the air when heated (aroma), and the smell that wafts into the mouth when inhaled (flavor).

[0018] "Smoking" generally means smoking tobacco, but here it simply means "enjoying smoke," "tasting smoke," or "enjoying smoke," and the source of smoke is not limited to tobacco, but also applies to non-tobacco materials. In addition, "smoke" here also includes "something that looks like smoke" or "something that is smoke-like," such as droplets dispersed in the air, such as aerosols.

[0019] An "e-cigarette compatible cartridge" is also defined as simply "a cartridge that can be used interchangeably (compatible) with an e-cigarette cartridge that contains tobacco components," regardless of whether it contains tobacco components or not.

[0020] More specifically, the objective of the present invention is to provide a cylindrical aroma cartridge which is attached so as to come into contact with a heating element of a heated smoking device having an electrically controlled heating element in a chamber, and which allows the user to enjoy the aerosol smoke and aromatic components generated by heating the heating element, in which a mouthpiece equipped with a filter for filtering at least the smoke and aromatic components and a heated aroma generating element wrapped with a heated aroma generating base material that comes into contact with at least the heating element are adjacent to each other and are wrapped in a cartridge exterior body, and the mouthpiece has a mechanism that has the function of increasing the amount of gas suction and the function of capturing fallen non-tobacco materials and other debris and dust, and the heated aroma generating element is equipped with a material that does not reduce the amount of gas suction and has a structure that prevents falling non-tobacco materials and other debris from falling off and dust. [Means for solving the problem]

[0021] That is, the aroma cartridge of the present invention comprises a heated aroma generating body wrapped with a heated aroma generating substrate that contacts a heating body, a mouthpiece equipped with a filter that filters the aerosol smoke and aroma components generated by heating from the heating body, and a cartridge exterior body that wraps around the outer periphery to connect the heated aroma generating body and the mouthpiece, and at least one of the heated aroma generating body and the mouthpiece has at least one of a means for optimizing inhalation of the smoke and the aroma components and a material for sustaining gas generation of the smoke and the aroma components.

[0022] The suction optimization means and the gas generation and maintenance material respectively refer to the following structures and materials. The suction optimization means is a structure that improves the suction amount of the mouthpiece, and a structure that prevents and captures the generation of fallen objects and dust such as non-tobacco materials of the heated aroma generating body. More specifically, it refers to a cavity that improves the suction amount by expanding the gas flow path provided in the filter that constitutes the mouthpiece, a shape reinforcing member that prevents a decrease in the suction amount due to deformation provided in the support that prevents the heated aroma generating body that constitutes the mouthpiece from moving toward the mouthpiece, a heat insulating material that prevents damage to the joint due to heat diffusion provided in the mouthpiece, and a cover material that prevents the generation of fallen objects and dust such as non-tobacco materials and a partition material that captures them. The gas generation and maintenance material is a material that does not block the flow path of the gas released from the heated aroma generating body. More specifically, these are a heated aroma-generating substrate having an improved internal structure through a manufacturing method, a heated aroma-generating substrate constituting a heated aroma-generating body with an optimized blending amount, inorganic particles present inside and / or on the surface of the heated aroma-generating substrate constituting a heated aroma-generating body, and a heated aroma-generating substrate with an improved filling rate.These structures and materials of the present invention will be described in detail below.

[0023] First, in the aroma cartridge of the present invention, the filter is made of fibers molded into a cylindrical shape and constitutes the whole or part of the mouthpiece, and the suction optimization means has a cavity provided in the filter so as not to penetrate in the longitudinal direction. This filter is made of commonly used cellulose acetate (CA) fibers or polyester fibers such as polyethylene terephthalate (PET), and the cavity improves the amount of suction because the flow rate of gas inhaled by a typical smoker is insufficient in the case of an aroma cartridge of a heated aroma generating device using a non-tobacco material.

[0024] There are no particular limitations on the shape or number of the cavities, which may be determined appropriately according to the type of heated aroma-generating body; however, taking into consideration the effect of increasing the amount of gas inhaled by a typical smoker and the difficulty of the manufacturing method of the cavity, it is preferable to have at least one cavity at either end or both ends in the longitudinal direction of the filter.

[0025] The cavity is formed at a position such that when the smoker inhales, the inhaled gas enters the entire oral cavity uniformly. When there is one cavity, it is preferable to form it on the central axis of the cylinder in the longitudinal direction of the filter. When there are two cavities, it is preferable to form them with the central axis of the cylinder in the longitudinal direction of the filter as the center of symmetry. Furthermore, when there are three or more filters, it is preferable to form them on the central axis of the cylinder in the longitudinal direction of the filter, and at positions rotationally symmetrical about the central axis of the cylinder in the longitudinal direction of the filter and the central axis of the cylinder in the longitudinal direction of the filter.

[0026] Furthermore, the shape of the cavity is preferably columnar or pyramidal from the viewpoint of the effect of increasing the amount of gas inhaled by a typical smoker and the difficulty of the manufacturing method of the cavity, but the shape of the columnar or pyramidal bottom surface is not limited. However, since it is efficient to form these cavities by typical mechanical drilling, electric discharge machining, or laser machining, from the viewpoint of workability, a cylindrical or conical shape is preferable.

[0027] Such a filter may constitute the entire mouthpiece by itself, or may be a part of the mouthpiece. When a part of the mouthpiece is a filter, the remaining part is preferably a cavity formed by the cartridge exterior. The arrangement of the filter and the cavity is not particularly limited, and the heated aromatic body and the filter may be adjacent to each other, or the heated aromatic body and the cavity may be adjacent to each other. The cartridge exterior is usually made of polyolefin resin such as PE or PP, PET resin, CA resin, thin film such as polylactic acid (PLA), thin paper, etc., and when a cavity is formed by the cartridge exterior, it is necessary to have a thickness sufficient to maintain the strength of the mouthpiece, although this varies depending on the material.

[0028] Furthermore, the mouthpiece may be provided with a member having a preferred function other than the filter to improve the function of the mouthpiece.Typical such members generally include a support member for preventing the heated aroma generating body from moving toward the mouthpiece, and a cooling member for cooling the aerosol former of the heated aroma generating body after it volatilizes, promoting the generation of smoke, and lowering the temperature of the gas, and may constitute the mouthpiece together with the filter.Only one of these members may be applied, or both may be applied.When either one of them is applied, it is disposed between the heated aroma generating body and the filter.When both are applied, the support member and the cooling member are disposed between the heated aroma generating body and the filter in this order or in the reverse order.

[0029] The reason why the temperature of the gas needs to be lowered by the cooling member is not only to cool and condense the volatilized aerosol former to generate smoke, but also to lower the temperature of the gas itself in an extremely short distance between the heating part of the aroma cartridge and the mouthpiece, as compared with a paper cigarette, so that a comfortable smoking experience can be enjoyed in the oral cavity. Therefore, the cooling member is preferably one that plays the role of a heat exchanger, and a cylindrical porous body having continuous holes with a high porosity or a cylindrical tube with many through holes is used. The porosity must be at least 50% or more, and is preferably 70 to 90%. As the material, polyolefin resins such as PE and PP, PET resins, CA resins, polylactic acid (PLA), etc. have been used, but it is more preferable to wrap metal foil such as aluminum with high thermal conductivity around these, or to use metal itself.

[0030] In this way, the mouthpiece makes it easy for the smoker to hold the aroma cartridge in the mouth, and has a filter that filters the gas and makes the taste of the gas milder as an essential component, and a support member and / or a cooling member can be provided as necessary. By using this structure, since it is the filter that prevents the gas from being sucked in, it is possible to shorten the length of the filter and increase the amount of inhalation. Therefore, instead of providing a cavity as described above, a mouthpiece structure that shortens the filter and increases the amount of inhalation was considered.

[0031] The length of the aroma cartridge itself and the length of the heated aroma generating body are determined according to the structure of the heated smoking tool, so when the filter of the mouthpiece is shortened, a part of the filter is replaced with a support member. Conventionally, the support member has a hollow cylindrical structure with a thin side thickness, and is made of inexpensive polyolefin resins such as polyethylene (PE) and polypropylene (PP), plastics such as CA resin, and paper, since it prevents the movement of the heated aroma generating body toward the mouthpiece, and cannot prevent the passage of gas. In order not to prevent the passage of gas, it is preferable that the support member is hollow and has a thin side thickness. However, if the filter is shortened and the length of such a support member is lengthened, a problem occurs that the mouthpiece is easily deformed.

[0032] In response to this problem, the present invention provides a support member structure in an aroma cartridge equipped with a mouthpiece composed of at least a filter and a support member, which prevents the mouthpiece from deforming and the amount of inhalation from decreasing, even if the length of the support member is increased and the thickness of the sides is reduced.

[0033] That is, in this aroma cartridge, the mouthpiece has a support member including a through hole that prevents the heated aroma generating body from moving toward the mouthpiece, the support member and the through hole have substantially the same central axis, and the suction optimization means includes a shape reinforcing member that is fixedly or movably arranged in the through hole. More specifically, this shape reinforcing member is configured with at least one or more plate-like members that have the axis of the support member and the through hole in the plane and contact the inner wall of the through hole. By arranging such a plate-like member in the cylindrical through hole of the support member, even if the length of the cylindrical support member is increased and the thickness of the side surface is reduced, there is no need to change the material, and it is possible to prevent the deformation of the support member. The shape of this plate-like member is preferably a cross section cut in the axial direction of the cylinder, that is, a rectangle, and from the viewpoint of the suction amount, the thinner the thickness, the more preferable, and the fewer the number, the more preferable, but considering the viewpoint of preventing deformation, it is preferable that the plate-like member is 2 to 4 pieces and has a thickness of 0.1 to 0.5 mm and is made of polyolefin resin.

[0034] Furthermore, in order to prevent deformation of the support member, it is more preferable that the shape reinforcement member comprises a concentric cylinder having a radius smaller than the radius of the through hole and having an axis approximately identical to the central axis of the cylinder between the support member and the through hole, and a plate-shaped member shaped so as to contact the inner wall of the through hole in the radial direction of the concentric cylinder on the outer circumferential side of the concentric cylinder, and from the viewpoint of gas suction, it is even more preferable that the concentric cylinder is hollow.

[0035] In this way, in an aroma cartridge using a mouthpiece including a support member on which a shape reinforcing member for preventing the heated aroma generating body from moving toward the mouthpiece is disposed adjacent to the heated aroma generating body, and a filter adjacent to the support member, the support member can optimize the suction of gas without deformation of the support member, but in order to control the suction of gas more widely, it is more preferable to use a filter having a cavity as the filter. Furthermore, a cooling member that can efficiently turn the volatilized aerosol pharma into aerosol smoke can be disposed between the filter and the support member. In either case, in order to further optimize the amount of suction, it is preferable to use a filter having a cavity as the filter.

[0036] On the other hand, as the amount of suction increases due to improvements in the filter and support member, the heat of the gas is more likely to be transferred by convection from the heating element to the filter, which may reduce the bonding strength between the components that make up the aroma cartridge. The locations of such bonding surfaces vary depending on the configuration of the aroma cartridge, but examples of such bonding surfaces include the interface between the heated aroma generating element and the filter, support member, cooling member, and cartridge exterior, the interface between the filter and the support member, cooling member, and cartridge exterior, the interface between the support member, the cooling member, and cartridge exterior, and the interface between the cooling member and the cartridge exterior, etc.

[0037] If the bonding strength of each interface is reduced, gas will leak, adversely affecting the amount of inhalation, so it is preferable to provide a heat insulating member between the heated aroma generating body and the mouthpiece. This heat insulating member is preferably a plastic heat insulating porous body such as a sponge with long continuous pores and a long flow path, rather than dispersing high-temperature gas throughout like the support member adjacent to the heated aroma generating body, and it is sufficient if it has the function of retaining and cooling to some extent. Therefore, the length of the heat insulating member is extremely short, there is no need for a cooling function up to the cooling member, and it is preferable to use it instead of the support member that prevents the heated aroma generating body from moving toward the mouthpiece.

[0038] Furthermore, in the case of a heated smoking device in which the chamber is covered by a heating element (Fig. 3) rather than a typical heated smoking device with a needle-shaped heating element at the bottom of the chamber (Fig. 2), the effect of heat on the aroma cartridge is greater and there is a significant decrease in the bonding strength at the interface between the components as described above, so it is necessary to provide a heat insulating member to prevent the decrease in bonding strength, i.e., the reduction in the amount of inhalation. Thus, from the perspective of eliminating the effect of heat from the heating element and preventing a reduction in the amount of inhalation, the present invention also provides an aroma cartridge in which a heat insulating member is interposed between the heated aroma-generating element and the mouthpiece as an inhalation optimization means.

[0039] Furthermore, since the heated aroma-generating substrate emits various aromas, the fiber component may be extremely reduced. In such a case, the amount of binder is adjusted, but the non-tobacco material cannot be significantly reduced in the blend ratio to maintain the aroma, and the non-tobacco material and other debris are more likely to be generated than usual. These debris are carried toward the mouthpiece by smoking, causing clogging of the gaps in the filter and cooling member, and drastically reducing the amount of inhalation. In addition, in the case of a heated aroma-generating substrate with such a blend, debris and dust are also likely to be generated when the aroma cartridge is inserted into the needle-shaped heating element.

[0040] Therefore, the present invention also provides an aroma cartridge in which a lid material is disposed at the end of the heated aroma-generating body on the mouthpiece side and a partition material is disposed at the end opposite the mouthpiece as an inhalation optimization means. Either the lid material or the partition material may be provided, or both, depending on the state of the heated aroma-generating base material and the heated aroma-generating body that binds them. The lid material and / or partition material prevent clogging of the filter and / or cooling member due to fallen objects or dust, and ensure a stable amount of inhalation.

[0041] The above describes a solution for structurally improving the optimization of gas suction from an aroma cartridge. However, in order to optimize suction, it is also necessary to improve the heated aroma generating body that releases gas when heated. The amount of gas released from the heated aroma generating body is closely related to the amount of suction described above, and this point will be explained below. In the present invention, a material that stabilizes the amount of gas released is called a gas generation sustaining material.

[0042] The reason why the improvement in the amount of gas released by heating the heated aroma-generating body is not sustained has already been explained, but since it is an important point in the present invention, it will be explained again. In an aerosol-forming body containing tobacco material, the fibers of the tobacco material maintain their clumped state, preventing the tobacco material from falling off and fusing. However, when a non-tobacco material that does not contain a large amount of fibers is used, a large amount of a binder that functions as a fiber must be used in order to stably maintain the clumped state of the heated aroma-generating substrate. Therefore, if the amount of binder increases, the density of the heated aroma-generating substrate increases, the gas flow path is closed, and it becomes difficult to inhale the inhaled components.

[0043] In addition, since the aerosol former is glycerin, propylene glycol, etc., which are liquid at room temperature, the more the binder, the more likely it is to bleed out from the heated aroma-generating substrate over time, and the heated aroma-generating substrates are fused together, closing the flow path between the heated aroma-generating substrates and making it difficult to suction the inhaled components. In addition, when such fusion occurs, not only does it become difficult to insert the heating element into the heated aroma-generating substrate, but the heating element may also be damaged. Conversely, if the amount of binder, etc. added is reduced and a gas flow path is secured, non-tobacco materials may fall off or dust may be generated, making it difficult to firmly maintain the shape of the aroma cartridge, and may be destroyed when inserted into the heating element. In addition, these may be inhaled into the oral cavity.

[0044] Therefore, in the present invention, it was first discovered that the above problems could be solved by a manufacturing method [apparatus] for a heated aroma-generating substrate. Note that, in the following, the manufacturing method comprising each step will be mainly described, but it is clear that there exists a manufacturing apparatus that can carry out the manufacturing method as a whole by being provided with means for carrying out each step. For this reason, the manufacturing method and the manufacturing apparatus will be described simultaneously (overlapped) as "step [means]" and "method [apparatus]" without overlapping descriptions.

[0045] The reason why the above-mentioned problems can be solved by the manufacturing method [apparatus] for the heated aroma-generating substrate is that the heated aroma-generating substrate is manufactured by drying and cutting a sheet formed from a composition in which materials selected from non-tobacco materials, aerosol formers, binders, anti-adhesion agents, flavorings, non-tobacco material extracts, antibacterial preservatives, etc. are dispersed or dissolved in a medium such as pure water or alcohol, and the sheet is molded by a papermaking method, a compression molding method such as a roll press or a press, or a casting method, etc., and the internal structure of the heated aroma-generating substrate changes in various ways depending on the manufacturing method [apparatus] in the molding and drying processes [means].

[0046] The basis for this is that, for example, in blends of different polymers, the phase separation structure of the blend is affected by the manufacturing method [apparatus] and manufacturing conditions, and in the case of emulsions and suspensions in which oil is dispersed in water, whether the blend is water-in-oil or oil-in-water is affected by various factors such as the type of oil, the blending ratio of oil and water, and the type of surfactant. And, it is almost impossible to analyze the clear difference in the structure of the heated aroma-generating base material due to the difference in such manufacturing method [apparatus] because the material system contained is complex, and it is considered that a great deal of effort is required to find an analytical method. The reason why the manufacturing method [apparatus] of polymer blends and emulsions is used as the basis for the fact that the substances blended are limited, there is a long history of research, and analytical methods are established, so the differences in structure caused by manufacturing conditions are clear.

[0047] Various methods [apparatuses] for producing a heated aroma-generating substrate have already been considered, and one example is as follows: A method [apparatus] for producing a heated aroma-generating filler by cutting a heated aroma-generating sheet produced by a process [means] of preparing a non-tobacco material by drying and grinding the non-tobacco material and then dry-mixing it, a process [means] of preparing a material selected from an aerosol former, a binder, an anti-adhesive agent, a flavoring, a non-tobacco material extract, an antibacterial preservative, etc., a process [means] of preparing pure water and alcohol, a wet-mixing process [means] of mixing all of these prepared materials together, a papermaking process [means] of producing a water-containing sheet from the slurry produced by the wet mixing, a molding process [means] of roll-pressing the paper-made water-containing sheet to produce a sheet, and a process [means] of drying the sheet produced in the molding process [means].

[0048] However, the heated aroma-generating base material produced by this method [device] has a problem in that it is difficult to maintain a lump state, a large amount of binder is required, and the heated aroma-generating base material is prone to fusing due to bleeding out of the aerosol former. Therefore, the amount of gas released from the heated aroma-generating body using this filling changes significantly over time, making it impossible for smokers to inhale a stable amount of gas.

[0049] The material for stabilizing the amount of gas released from the heated aroma generating body in the aroma cartridge of the present invention, i.e., the gas generation sustaining material, is produced by a first dry mixing step [means] of mixing dried and ground non-tobacco material, a first wet mixing step [means] of mixing the non-tobacco material produced in the dry mixing step [means] with a material selected from an aerosol former, a binder or thickener, cross-linked polyvinylpyrrolidone (PVP), a flavoring, a non-tobacco extract, β-cyclodextrin, microcrystalline cellulose, and an antimicrobial preservative, into an alcohol and pure water mixture, and a second wet mixing step [means] of mixing the non-tobacco material produced in the dry mixing step [means] with a material selected from an aerosol former, a binder or thickener, cross-linked polyvinylpyrrolidone (PVP), a flavoring, a non-tobacco extract, β-cyclodextrin, microcrystalline cellulose, and an antimicrobial preservative, into an alcohol and pure water mixture. The heated aroma-generating substrate is produced by a second wet mixing process [means] in which pure water and / or alcohol is further added to the alcohol and pure water mixture containing the non-tobacco materials, etc. to produce a slurry containing the non-tobacco materials, etc.; a papermaking process [means] in which a moisture-containing sheet is produced from the slurry produced in the second wet mixing process [means]; a sheet forming process [means] in which the moisture-containing sheet is compressed and processed into a sheet; a drying process [means] in which the sheet produced in the sheet forming process [means] is dried to produce a heated aroma-generating sheet; and a sheet processing process [means] in which the heated aroma-generating sheet is cut or folded.

[0050] The manufacturing method [apparatus] is characterized by the second wet mixing. This second wet mixing with the addition of pure water and alcohol improves the dispersion state of the aerosol former such as polypropylene glycol or glycerin and the non-tobacco material, so that the mass state of the heated aroma-generating base material can be stabilized and the bleed-out of the aerosol former can be reduced without increasing the amount of binder added. In particular, lower monoalcohols such as ethanol and propanol are effective and preferable as the alcohol, and the amount added is preferably 0.1 to 10 parts by mass per 100 parts by mass of the non-tobacco material.

[0051] The gas generation-sustaining material in the second aroma cartridge of the present invention is prepared by a dry mixing step [means] of mixing dried and ground non-tobacco materials, a first wet mixing step [means] of mixing the non-tobacco materials produced in the dry mixing step [means] with an aerosol former, a binder or thickener, cross-linked PVP, a flavoring, a non-tobacco extract, β-cyclodextrin, microcrystalline cellulose, and an antimicrobial preservative, into an alcohol and pure water mixture, and a second wet mixing step [means] of further adding pure water and / or alcohol to the alcohol and pure water mixture containing the non-tobacco materials, etc. produced by the first wet mixing step [means] to produce a slurry containing the non-tobacco materials, etc. the heated aroma-generating substrate is produced by a wet mixing process [means], a papermaking process [means] of producing a moisture-containing sheet from the slurry produced in the second wet mixing process [means], a sheet forming process [means] of compressing or casting the moisture-containing sheet to process it into a sheet, an aerosol former absorbing process [means] of applying or immersing an aerosol former in the moisture-containing sheet whose moisture content has been reduced to less than 50% by the sheet forming process [means], a drying process [means] of drying the sheet produced in the aerosol former absorbing process [means] to produce a heated aroma-generating sheet, and a sheet processing process [means] of cutting or folding the heated aroma-generating sheet.

[0052] The manufacturing method [apparatus] is also characterized by the second wet mixing, and the alcohol is preferably a lower monoalcohol such as ethanol or propanol, and the amount added is preferably 0.1 to 10 parts by mass per 100 parts by mass of the non-tobacco material, as in the first manufacturing method [apparatus]. However, the second manufacturing method [apparatus] is characterized by the addition of an aerosol former absorption step [means] of applying or immersing the aerosol former in a water-containing sheet whose moisture content has been reduced to less than 50% by mass. In the conventional manufacturing method [apparatus], the aerosol former and the non-tobacco material were poorly dispersed, and the aerosol former and the non-tobacco material were separated in the undried heated aroma-generating base sheet whose moisture content was less than 50% by mass, making it difficult to absorb the aerosol former. However, since the dispersion state is improved by the second wet process [means], the aerosol former is absorbed into the inside of the sheet in the aerosol former absorption process [means]. Therefore, even if the amounts of aerosol former and binder added are the same as in the first manufacturing method [apparatus], the clumpy state of the heated aroma-generating base material can be stabilized, the bleed-out of the aerosol former can be reduced, and the aerosol former can be more easily volatilized by heating.

[0053] The gas generation-sustaining material in the third aroma cartridge of the present invention includes a wet mixing step [means] of mixing a dried and ground non-tobacco material with pure water to produce a slurry of the non-tobacco material, a papermaking step [means] of producing a water-containing sheet from the slurry produced in the wet mixing step [means], a sheet forming step [means] of compressing or casting the water-containing sheet into a sheet, a drying step [means] of reducing the moisture content of the sheet produced in the sheet forming step [means] to less than 50% by mass, and aerosol particles being added to the sheet produced in the drying step [means]. the heated aroma-generating substrate is manufactured through an absorption and adsorption process [means] in which a mixture of alcohol and pure water of materials selected from the group consisting of cellulose, a binder or thickener, cross-linked PVP, flavoring, non-tobacco extract, β-cyclodextrin, microcrystalline cellulose, a concentrated solution of the water discharged in the sheet forming process [means], and an antibacterial preservative is applied to or soaked in the mixture; a drying process [means] in which the sheet manufactured in the absorption and adsorption process [means] is dried to manufacture a heated aroma-generating sheet; and a sheet processing process [means] in which the heated aroma-generating sheet is cut or folded.

[0054] In the first and second manufacturing methods [apparatuses], all materials such as non-tobacco materials are wet mixed with pure water and alcohol to form a wet sheet, but the third manufacturing method [apparatus] is characterized in that a wet seed is produced from a slurry of non-tobacco materials alone, and the dried sheet is made to absorb and adsorb other materials such as aerosol formers. In the first and second manufacturing methods [apparatuses], the dispersion of non-tobacco materials and aerosol formers is improved, but the wet dispersion of all materials itself is problematic. As a result of considering a manufacturing method [apparatus] that does not go through the process [means] of mixing and dispersing non-tobacco materials and aerosol formers, it was found that a pure water and alcohol mixture of other materials such as aerosol formers quickly penetrates, absorbs, and adsorbs into a dried sheet of non-tobacco materials, as in the third manufacturing method [apparatus], and the present invention was achieved. The mass state of the heated aroma-generating substrate produced by this method [apparatus] is stable, and the bleed-out of the aerosol formers is also reduced.

[0055] The gas generation-sustaining material in the fourth aroma cartridge of the present invention includes a non-tobacco material preparation step [means] of drying and crushing a non-tobacco material, a flavor and / or non-tobacco extract mixing step [means] of mixing at least a flavor and / or a non-tobacco material extract with cross-linked PVP and / or β-cyclodextrin in alcohol to retain the flavor and / or non-tobacco extract in the cross-linked PVP and / or β-cyclodextrin, and an aerosol preparation step [means] of mixing at least an aerosol former and a binder or thickener in pure water. The heated aroma-generating substrate is manufactured through a wet mixing process [means] in which the material produced in the non-tobacco material preparation process [means], the material produced in the flavoring and / or non-tobacco extract dissolving process [means], and the material produced in the aerosol former dissolving process [means] are mixed together, a sheet forming process [means] in which the material produced in the wet mixing process [means] is compressed to produce a heated aroma-generating sheet, and a sheet processing process [means] in which the heated aroma-generating sheet is cut or folded.

[0056] Previous manufacturing methods [apparatuses] were characterized by forming a sheet from a slurry of non-tobacco materials, etc., through a papermaking process [means], but in light of the results of the third manufacturing method [apparatus], since casting a sheet from a slurry of materials with various different properties, such as non-tobacco materials, is problematic in itself, a mixture of non-tobacco materials, etc., with low amounts of pure water and alcohol and high viscosity is formed into a sheet of the heated aroma-generating substrate using a roll press such as a three-roll press, without going through a slurry of a large amount of pure water and alcohol. In this method [apparatus], large shearing and compressive forces are applied to the mixture of non-tobacco materials, etc., so it is thought that all the materials are uniformly kneaded and dispersed.

[0057] Here, it is important to provide a mixing process [means] in which at least the flavoring and / or non-tobacco extract is mixed with cross-linked PVP and / or β-cyclodextrin in alcohol to retain the flavoring and / or non-tobacco extract in the cross-linked PVP and / or β-cyclodextrin, and an aerosol former dissolving process [means] in which at least the aerosol former and a binder or thickener are mixed in pure water, and to dissolve in advance materials that can be dissolved in pure water and alcohol, such as the flavoring, non-tobacco extract, aerosol former, binder or thickener. In particular, when menthol and / or xylitol are used as flavorings, these are sorbed by the cross-linked PVP and / or β-cyclodextrin and remain stable in the heated aroma-generating substrate, which has the effect of suppressing bleed-out of the aerosol former. Therefore, the mixing process [means] of mixing at least the flavoring and / or non-tobacco extract with the cross-linked PVP and / or β-cyclodextrin in alcohol to retain the flavoring and / or non-tobacco extract in the cross-linked PVP and / or β-cyclodextrin plays an extremely important role.

[0058] By adopting this manufacturing method [apparatus], the mass state of the heated aroma-generating base material is stable, the bleeding out of the aerosol former can be significantly reduced, there is no fusion of the heated aroma-generating base material, the evaporation of gas by heating the heated aroma-generating body is promoted, and a decrease in the amount of inhalation over time can be prevented.

[0059] Furthermore, in the sheet forming step (means) of this manufacturing method (apparatus), it is preferable to add a step (means) of adding a material selected from non-tobacco materials, aerosol formers, binders or thickeners, cross-linked PVP, flavorings, non-tobacco extracts, β-cyclodextrin, microcrystalline cellulose, antibacterial preservatives, and pure water. This step (means) can promote kneading by shear force and compression force in the sheet forming step (means), control the moisture content, and increase the volatility of the aerosol former.

[0060] The gas generation-sustaining material in the fifth aroma cartridge of the present invention is a heated aroma-generating substrate produced by a first wet mixing step [means] of mixing dried and ground non-tobacco material, a first binder aqueous solution in which a first binder is dissolved in pure water, and a material selected from an aerosol former, cross-linked PVP, flavoring, non-tobacco material extract, β-cyclodextrin, microcrystalline cellulose, and an antibacterial preservative, a curing step [means] of stabilizing the mixed liquid produced in the first wet mixing step [means], a second wet mixing step [means] of mixing the curing mixed liquid produced in the curing step [means] with a second binder aqueous solution in which a second binder is dissolved in pure water, a sheet forming step [means] of compressing the material produced in the second wet mixing step [means] to produce a heated aroma-generating sheet, and a sheet processing step [means] of cutting or folding the heated aroma-generating sheet. In this manufacturing method [apparatus], as in the fourth manufacturing method [apparatus], it is preferable to add a step [means] of adding a material selected from non-tobacco material, an aerosol former, a binder or thickener, cross-linked PVP, flavoring, a non-tobacco extract, β-cyclodextrin, microcrystalline cellulose, an antibacterial preservative, and pure water to the sheet forming step [means].

[0061] This manufacturing method [apparatus] is characterized in that it includes a step [means] of curing the mixed liquid, and a step [means] of adding a binder in two separate steps, before and after the curing step [means]. The binder is preferably a modified cellulose-based polymer in the first step, and a polysaccharide-based polymer other than cellulose in the second step.

[0062] The curing process [means] refers to a change in the dispersion state of the mixture of non-tobacco materials, etc. over time, and is presumed to lead to the lowest energy, stable, uniform dispersion state, and it is believed that this change in state makes it possible to form a lump-like state of the heated aroma-generating base material.

[0063] In addition, by adding the binder in two separate times, the mixture can be sufficiently dispersed even if the amount of binder added is reduced, and viscosity adjustment is easy, which is closely related to the curing process [means]. Since a stable dispersion state is created by adding the binder in the first time and curing, it becomes easy to add the binder in the second time, the amount added can be reduced, and viscosity adjustment is easy. Therefore, in the first time, modified cellulose-based polymers with superior dispersion ability are preferred, and in the second time, polysaccharide-based polymers other than cellulose-based polymers with superior ability as a thickener to adjust viscosity are preferred.

[0064] As such modified cellulose polymers, it is preferable to use one or more of methyl cellulose, ethyl cellulose, carboxymethyl cellulose, carboxyethyl cellulose, hydroxymethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, and sodium salts, potassium salts, and calcium salts of carboxymethyl cellulose and carboxyethyl cellulose, and as polysaccharide polymers, it is preferable to use one or more of konjac mannan (glucomannan), guar gum, pectin, carrageenan, tamarin seed gum, gum arabic, soybean polysaccharides, locust bean gum, karaya gum, xanthan gum, and agar.

[0065] The blending amounts of the binders are preferably 5 to 20 parts by mass of the first binder and 0.1 to 5 parts by mass of the second binder per 100 parts by mass of the non-tobacco material.

[0066] There are also suitable conditions for the curing process [means] that leads to a stable dispersion state, and it is preferable to carry out the process at 15 to 30°C for 72 to 336 hours. The suitable temperature conditions are considered to be due to the fact that the presence or absence of hydrogen bonds brings about differences in the molecular state dissolved in pure water and alcohol, as the binder is a polymer having hydroxyl groups and carboxyl groups, and this difference depends on the temperature, and the optimal temperature range was derived as a result of experiments. The dispersion state changes over time, and a minimum time is required until it becomes stable, but if more time is required than necessary, there will be no significant changes and productivity will decrease.

[0067] We have explained above the solution of optimizing the manufacturing method [apparatus] of the material that stably releases gas from the heated aroma-generating body, i.e., the heated aroma-generating base material that serves as the gas generation-sustaining material. However, we have now devised a material that more actively releases gas stably.

[0068] This gas generation sustaining material is inorganic particles. The effect of inorganic particles is in two ways depending on the location where it is present. One is when inorganic particles are present inside the heated aroma filling. By adding inorganic particles to the heated aroma generating body, the density of the heated aroma generating substrate is reduced, the gas flow path is eliminated, and the gas is not difficult to suck. The other is when inorganic particles are on the surface of the heated aroma generating sheet or heated aroma generating substrate. Even if the aerosol former bleeds out from the heated aroma generating substrate over time, the inorganic particles can prevent the fusion phenomenon between the heated aroma generating substrates, and the flow path between the heated aroma generating sheet or heated aroma generating substrate is not closed, and the problem of the difficulty in sucking the suction component is solved. In addition, since the fusion of the heated aroma generating sheet or heated aroma generating substrate is eliminated, the problem of the difficulty in inserting the heating element into the heated aroma generating substrate is also solved. Furthermore, introducing inorganic particles into the heated aroma-generating body reduces the contact area between the heating body and the organic components of the heated aroma-generating substrate, regardless of whether the particles are inside or on the surface of the heated aroma-generating substrate, thereby having the effect of reducing contamination of the heating body of the heated smoking device.

[0069] In order to have such inorganic particles present inside the heated aroma-generating substrate as a gas generation sustaining material, they may be added to the heated aroma-generating substrate composition as a raw material in the manufacturing process of the heated aroma-generating substrate described above. The step [means] of adding the inorganic particles is not particularly limited, but it is preferable to add them before wet mixing with tobacco material, etc.

[0070] On the other hand, in order to have the inorganic particles present on the surface of a heated aroma-generating substrate, the five manufacturing methods [apparatuses] mentioned above include a step [means] of spraying the inorganic particles onto the heated aroma-generating sheet after the step [means] of producing the heated aroma-generating sheet, and a step [means] of spraying the inorganic particles onto the heated aroma-generating substrate after the sheet processing step [means] of producing the heated aroma-generating substrate.

[0071] The inorganic particles are preferably metal oxides such as magnesium oxide, calcium oxide, titanium oxide, iron oxide, and alumina, metal carbonates such as magnesium carbonate and calcium carbonate, metal phosphates such as calcium phosphate, titanates such as potassium titanate and magnesium titanate, and silicon oxides such as zeolite, colloidal silica, and fumed silica, and more preferably have an average particle size of 1 to 100 μm. Furthermore, in order for the inorganic particles to function effectively, it is preferable that 0.1 to 10 parts by mass of the inorganic particles are added per 100 parts by mass of the non-tobacco material.

[0072] As described above, the aroma cartridge of the present invention comprises a heated aroma generating body wrapped with a heated aroma generating substrate that contacts the heating body, a mouthpiece equipped with a filter that filters the smoke and aroma components of the aerosol generated by heating from the heating body, and a cartridge exterior body that wraps the outer periphery to connect the heated aroma generating body and the mouthpiece, and at least one of the heated aroma generating body and the mouthpiece has at least one of a means for optimizing inhalation of smoke and aroma components and a material for sustaining gas generation of smoke and aroma components. The inhalation optimization means and the gas generation sustaining material in the aroma cartridge of the present invention have been described above, but the invention that complements these will be described below.

[0073] First, for stable gas inhalation, it is preferable that the filling rate of the heated aroma-generating substrate constituting the heated aroma-generating body is 60 to 90%. If the filling rate exceeds this rate, it is difficult to inhale the gas, and if the filling rate is less than this rate, the amount of gas released is insufficient. In particular, in order to prevent the heated aroma-generating substrate from fusing over time, the filling rate is preferably 60 to 73%. If the filling rate exceeds 73%, the fusing over time of the heated aroma-generating substrate becomes noticeable. However, this is not the case in the case of the heated aroma-generating substrate manufactured by the above-mentioned improved manufacturing method [apparatus] and the heated aroma-generating substrate having inorganic particles present inside or on the surface, and even if the filling rate exceeds 73%, the fusing over time does not become severe.

[0074] The amount of aerosol former contained in the heated aroma-generating substrate is preferably 50 to 80 parts by mass per 100 parts by mass of non-tobacco material. If the amount is less than this amount, the amount of aerosol former that volatilizes to form an aerosol will be insufficient, and if the amount is more than this amount, the aerosol former will bleed out excessively from the heated aroma-generating substrate, causing the heated aroma-generating substrate to fuse excessively.

[0075] Furthermore, the crosslinked PVP stabilizes the lump state of the heated aroma-generating base material and also plays a role in retaining aroma components such as menthol, xylitol, etc., and is preferably present in an amount of 7 to 25 parts by mass per 100 parts by mass of the non-tobacco material. If the amount is less than this, the function of the crosslinked PVP cannot be expressed, and if the amount is exceeded, the aroma components from the non-tobacco material, etc. will be insufficient.

[0076] The amount of microcrystalline cellulose is preferably 7 to 25 parts by mass per 100 parts by mass of the non-tobacco material. This microcrystalline cellulose is a flowable powder that does not dissolve in organic solvents such as water and ethanol, and is used as an excipient for pharmaceutical tablet molding. This is because the flowability and high compressibility of microcrystalline cellulose, which has a large volume change, are effective in preventing cohesive failure and adhesion to a mold when molding tablets by direct compression. The same effect is also observed in the heated aroma-generating substrate, and this function cannot be expressed if the amount is less than the above amount. Conversely, if the amount is more than this amount, the mixing ratio of other materials becomes relatively insufficient, which adversely affects the function as a heated aroma-generating substrate.

[0077] Finally, the amount of β-cyclodextrin is preferably 0.2 to 1.0 parts by mass per 100 parts by mass of the non-tobacco material. Since β-cyclodextrin plays a role in retaining aroma components such as menthol and xylitol, at least this amount is necessary, but adding an excessive amount inhibits its function as a heated aroma-generating base material. In particular, it is known to encapsulate menthol, so adding it is preferable when menthol is used as an aroma component.

[0078] Below, constituent materials particularly suitable for the heated aroma-generating substrate of the present invention are listed.

[0085] Teas can also be used. Not only do different plants produce different teas, but even the same plant can produce different teas depending on the processing method (apparatus), so all of them are preferred as non-tobacco materials with different aromatic components.

[0097] The aroma cartridge equipped with the inhalation optimization means of the present invention uses no tobacco components and can solve the problem specific to aroma cartridges using non-tobacco materials, that is, the reduction in the amount of gas inhaled by the smoker due to the blockage of the gas flow path inside and between the heated aroma-generating substrates. On the other hand, an aroma cartridge equipped with a gas generation-sustaining material can improve the reduction in the amount of gas released due to the blockage of the gas flow path itself, and can provide an aroma cartridge that does not cause the non-tobacco materials to fall off or generate dust.

[0098] In addition, the heated aroma-generating body having inorganic particles as the gas generation-sustaining material of the present invention prevents fusion between heated aroma-generating base materials, and also solves the problem of an aroma cartridge that has been stored for a long period of time being unable to be attached to the heating element of a heated smoking device, and the problem of the heating element being damaged or contaminated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0100] The present invention will be described in more detail below using drawings and embodiments, but the present invention is not limited to these and can be implemented in various modifications within the scope that does not deviate from the gist of the present invention, and is limited only by the technical ideas described in the claims.

[0101] 1 is a schematic diagram showing the general structure of a cylindrical aroma cartridge that is attached so as to contact a heating element of a heated smoking tool having an electrically controlled heating element in a chamber, and allows the user to enjoy the aerosol smoke and aroma components generated by heating the heating element, and the steps (means) of the manufacturing method (apparatus). The aroma cartridge of the present invention is basically similar in structure and assembled in the same manner, except that no tobacco components are used as the heated aroma generating element that generates the aerosol that is heated by the heating element and released. That is, the aroma cartridge of the present invention is connected in a state where the heated aroma generating element, which is wrapped with a heated aroma generating base material made of non-tobacco material and aerosol former, and the outside of the heated aroma generating element and the mouthpiece are wrapped with a cartridge exterior body and connected adjacent to each other in the longitudinal direction in which the heated aroma generating element is attached so as to contact the electrically controlled heating element.

[0102] 2 and 3 show the state in which such an aroma cartridge is attached to a heated smoking device and smoked, for two types of heating element. In order to clarify the features of the aroma cartridge of the present invention, a mechanism for enjoying the aroma cartridge by attaching it to a heated smoking device will be briefly described.

[0103] FIG. 2(A) shows an electrically heated smoking device (1) having a needle-shaped electrically controlled heating element 113 provided at the bottom of a chamber 112 housed in a casing 111. 11 FIG. 2(B) is a schematic cross-sectional view of the aroma cartridge. 2 1 is a schematic cross-sectional view of a heated aroma generating unit 21 wrapped with an inner material 21-p and a mouthpiece 22 wrapped with an inner material 22-p, which constitute a heated smoking device (1). 11The electrically heated smoking device (1) is wound and connected by the cartridge exterior body 23 in a state adjacent to the longitudinal direction. 11 Using the aromatic cartridge 2 The state of inhaling the aroma cartridge shown in FIG. 2 The heated aroma generating element 21 side of the casing 111 is inserted into the chamber 112, and the heated aroma generating element 21 is thrust into the electrically controlled heating element 113. When the smoker presses a switch, not shown, the electrically controlled heating element 113 is heated in accordance with a signal from an electrical control unit, not shown, and aerosol smoke and aroma components are released from the heated aroma generating element 21, which are then inhaled. When the smoker inhales, as shown by arrow W, air enters from the intake port 115 and passes through the gap between the casing 111 and the chamber 112, carrying the aerosol former and aroma components volatilized from the heated aroma generating element 21 to the mouthpiece 22 and inhaled into the smoker's mouth. The smoke is cooled in the mouthpiece 22 and inhaled as an aerosol.

[0104] FIG. 3(A) shows an electrically heated smoking device (2) having an electrically controlled heating element 123 provided on the outer periphery of a chamber 122 housed in a casing 121. 12 FIG. 3(B) is a schematic cross-sectional view of a smoker using an electrically heated smoking device (2). 12 Using the aromatic cartridge 2 The state in which the aroma cartridge shown in FIG. 2 When the heated aroma generating element 21 side is inserted into the chamber 122 through the aroma cartridge insertion port 124, the heated aroma generating element 21 is surrounded by the electrically controlled heating element 123. When a switch (not shown) is pressed, the electrically controlled heating element 123 is heated in accordance with a signal from the electrical control unit 1231, and aerosol smoke and aroma components are emitted from the heated aroma generating element 21, which are inhaled. When the smoker inhales, air enters from the intake hole 125, as shown by the arrow W, and the aerosol former and aroma components volatilized from the heated aroma generating element 21 are carried to the mouthpiece 22 and inhaled into the smoker's mouth. The smoke is cooled in the mouthpiece 22 and inhaled as an aerosol.

[0105] In this type of smoking, aroma cartridges made only of non-tobacco materials have the advantage that they do not produce substances harmful to the human body, such as tar and nicotine, and allow the enjoyment of a variety of flavors, such as beverages such as coffee, cola, and Red Bull, desserts such as chocolate, vanilla, and cream, fruits such as orange, lemon, and melon, and refreshing agents such as menthol, mint, and herbs. However, they have problems due to the use of a wide variety of non-tobacco materials to release various flavors as substitutes for tobacco materials, which contain a large amount of fiber.

[0106] In an aerosol-forming body containing tobacco material, the fibers of the tobacco material maintain the clumped state and prevent the tobacco material from falling off and fusing, but in order to stably maintain the clumped state of a heated aroma-generating substrate containing a non-tobacco material that does not contain a large amount of fibers, it is necessary to blend a large amount of a binder or the like that performs the function of fibers.As a result, the density of the heated aroma-generating substrate increases, the gas flow path is closed, and it becomes difficult to inhale the inhaled components, resulting in a decrease in the amount of inhalation.

[0107] In addition, since the aerosol former is made of glycerin, propylene glycol, etc., which are liquid at room temperature, the more the binder is added, the more it bleeds out from the heated aroma-generating substrate over time, causing the heated aroma-generating substrates to fuse together. This closes the gas flow path, making it difficult to suck in the aroma components, and as a result, the amount of suction decreases. In addition, when such fusion occurs, not only does it become difficult to insert the heating element into the heated aroma-generating substrate, but it may also damage the heating element.

[0108] Conversely, if the amount of binder, etc. added is reduced and a gas flow path is ensured, non-tobacco materials may fall off or dust may be generated, making it difficult to firmly maintain the shape of the aroma cartridge, and the cartridge may break when inserted into the heating element. These may also be inhaled into the oral cavity.

[0109] The present invention aims to provide a means for solving these problems. That is, it provides a means for securing a gas flow path and preventing a decrease in the amount of inhalation. However, a solution method of significantly changing the composition or blending ratio of the heated aroma-generating base material cannot be adopted because of the need to maintain the generation of aerosols that become smoke and the generation of aroma components released from non-tobacco materials. Therefore, the present invention provides a means for solving the problems from two different perspectives.

[0110] One is a physical solution that focuses on the structure of the mouthpiece that constitutes the aroma cartridge and has a large effect on the amount of inhaled. The other is a chemical solution that focuses on the manufacturing method [apparatus] for the heated aroma-emitting substrate and its filling state.

[0111] The former physical solution is to provide an aroma cartridge equipped with a suction optimization means for improving the amount of suction in the mouthpiece, and to provide an aroma cartridge equipped with a suction optimization means for preventing a decrease in the amount of suction by capturing fallen objects such as non-tobacco materials and dust in the heated aroma generating body. More specifically, it is to provide an aroma cartridge in which a filter constituting the mouthpiece, a support for preventing the heated aroma generating body constituting the mouthpiece from moving toward the mouthpiece, and a cavity for improving the amount of suction by expanding the gas flow path, a shape reinforcing member for preventing a decrease in the amount of suction due to deformation, and a heat insulating material for preventing damage to the joint due to heat diffusion are respectively provided in the mouthpiece as the suction optimization means. It is also to provide an aroma cartridge in which a lid material and / or a partition material for preventing and capturing fallen objects such as non-tobacco materials and dust are provided in the heated aroma generating body as the suction optimization means.

[0112] The latter chemical solution is to provide a heated aroma-generating body with an aroma cartridge equipped with a gas generation and maintenance material that does not reduce the amount of suction. More specifically, the aroma cartridge is provided with a heated aroma-generating body with, as gas generation and maintenance materials, a heated aroma-generating substrate with an improved internal structure by a manufacturing method [apparatus], a heated aroma-generating substrate with an optimized blending amount, inorganic particles present inside and / or on the surface of the heated aroma-generating substrate, and a heated aroma-generating substrate with an improved filling rate.

[0113] These inhalation optimization means and gas generation and maintenance materials can exert a sufficient effect alone, so Fig. 4 shows the configuration of an aroma cartridge in which a heated aroma generator having no gas generation and maintenance material is joined to a mouthpiece having an inhalation optimization means, and Fig. 33 shows the configuration of an aroma cartridge in which a heated aroma generator having a gas generation and maintenance material is joined to a mouthpiece having no inhalation optimization means. However, higher or wider effects can be obtained by using them in combination, so an extremely wide variety of aroma cartridges can be provided, consisting of all combinations of heated aroma generators and mouthpieces shown in Figs. 4 and 33.

[0114] First, the inhalation optimization means will be described in detail with reference to the drawings. Fig. 5 shows an aroma cartridge according to one embodiment of the present invention, in which a mouthpiece 221-1, which is made of a filter unit 221-1 for filtering gas and in which one cavity 221-1-c1 is formed, and a heated aroma generating unit 21 are adjacent to each other, and are joined and wrapped with a cartridge exterior body 23. 2-1 The cavity 221-1-c1 is disposed in the filter 221-1 at the end of the filter 221-1 on the side of the heated aroma generating unit 21 in the longitudinal direction thereof, so that the central axis o of the right circular cylinder of the filter 221-1 and the cavity 221-1-c1 are substantially aligned. 2-1 For example, the outer diameters of the aroma cartridge, the heated aroma generating body, and the mouthpiece are as shown in Figs. 11 ya(2) 12These are determined by the above and may be set appropriately, but below, the outer diameter j and length k of the aroma cartridge are set to 6.9 mm and 45 mm, respectively, the length a of the heated aroma generating body is set to 12 mm, and the length m (= f) of the mouthpiece (= filter) is set to 33 mm.

[0115] The longer and wider the cavity is, the greater the amount of suction can be. However, due to issues with the strength of the mouthpiece, the length c1, inner diameter b1, and surface area are set to 10-25 mm, 1-4 mm, and 34.54-326.54 mm, respectively. 2 In the embodiment of FIG. 5, a right cylindrical cavity having a length c1 of 20 mm and an inner diameter of 3 mm is formed. The shape of the cavity is not limited to a right cylindrical cavity, but may be an oblique cylindrical shape as well, as long as the hole does not penetrate the filter. However, in consideration of uniform gas suction into the oral cavity and processability, a shape symmetrical about the central axis of the filter is preferable, and a columnar shape such as a triangular prism, a square prism, or a pentagonal prism, and a pyramidal shape such as a cone (FIG. 9), a triangular pyramid, a square pyramid, or a pentagonal pyramid are preferable.

[0116] Furthermore, although the cavity in FIG. 5 is formed at the end of the filter on the heated aroma generating unit side in the longitudinal direction, it may be provided at the opposite end.

[0117] FIG. 6 shows an aroma cartridge according to one embodiment of the present invention, in which a mouthpiece 221-2, which is made up of a filter unit 221-2 for filtering gas and in which two cavities 221-2-c2 and 221-2-c3 are formed, and a heated aroma generating unit 21 are adjacent to each other, and are joined and wrapped with a cartridge exterior body 23. 2-2 The cavities 221-2-c2 and 221-2-c3 are disposed in the filter 221-2 at both ends in the longitudinal direction of the filter 221-2 such that the central axes o of the right circular cylinders of the filter 221-2, the cavities 221-2-c2 and 221-2-c3 are substantially aligned with each other. 2-2The shape of the cavity that can improve the amount of inhalation is such that the longer and wider it is, the greater the amount of inhalation can be. However, due to problems with the strength of the mouthpiece, it is preferable that the lengths c2 and c3 are 5 to 15 mm, the outer diameters b2 and b3 are 1 to 3.5 mm, and the total surface area is 34.54 to 326.54 mm. 2 The shape is as described in the description of FIG.

[0118] FIG. 7 shows a right cylindrical aroma cartridge according to one embodiment of the present invention, in which a mouthpiece 221-3 constituted by a filter unit 221-3 for filtering gas in which four cavities 221-3-c4 are formed, and a heated aroma generating unit 21 are adjacent to each other, and are joined and wrapped with a cartridge exterior body 23. 2-3 The cavity 221-3-c4 is a right circular cylinder, and is disposed in the filter 221-3 from the end of the filter 221-3 on the side of the heated aroma generating unit 21 in the longitudinal direction of the filter 221-3 at a rotationally symmetrical position about the central axis of the right circular cylinder in the longitudinal direction of the filter 221-3. 2-3 7 is a schematic diagram showing a preferred example of a filter having four cavities. However, the present invention is not limited to this example, and the number of cavities may be two or more. As in the description of FIG. 6, the number and size of the cavities are appropriately set according to the balance between the suction amount and the strength of the filter. 2 The shape is as described in the explanation of Fig. 5. Also, the cavity in Fig. 7 is formed at the end of the filter on the heated aroma generating unit side in the longitudinal direction, but it may be provided at the end opposite to this end.

[0119] FIG. 8 shows a right cylindrical aroma cartridge according to one embodiment of the present invention, in which a mouthpiece 221-4, which is made up of a filter unit 221-4 for filtering gas and in which five cavities 221-4-c5 and 221-4-c6 are formed, and a heated aroma generating unit 21 are adjacent to each other, and are joined and wrapped with a cartridge exterior body 23. 2-4all of the cavities are shaped like right cylinders, four cavities 221-4-c5 are disposed in the filter from the end of filter 221-4 on the side of heated aroma generating body 21 in the longitudinal direction, at positions rotationally symmetrical about the central axis of the right cylinder in the longitudinal direction of filter 221-4, and one cavity 221-4-c6 is disposed in the filter from the end of filter 221-4 on the opposite side of the heated aroma generating body 21 in the longitudinal direction, such that the central axes of the right cylinders of filter 221-4 and cavity 221-4-c6 are substantially aligned. 2-4 8 is a schematic diagram showing an example in which the number of cavities 221-4-c5 at the end of the filter on the side of the heated aroma generating body is four and the number of cavities 221-4-c6 on the opposite side is five, but the number and size of the cavities are not limited to these and are appropriately set according to the balance between the amount of suction and the strength of the filter as described in FIG. 2 It is preferable that the shape is as described in the description of FIG.

[0120] Fig. 9 shows a modified cavity shape, in which a right circular cone-shaped cavity 221-5-d1 is used in the aroma cartridge 2-1 shown in Fig. 5. In this case as well, the surface area is 34.54 to 326.54 mm 2 The dimensions of the right circular cone-shaped cavity can be appropriately designed so that the cavity satisfies the following formula: In addition, in Fig. 9, the cavity is formed at the end of the filter on the side of the heated aroma-generating unit 21 in the longitudinal direction, but it may be provided at the end opposite to this end.

[0121] FIG. 10 also shows a modified cavity shape, which is the same as the aroma cartridge shown in FIG. 2-3 In this case, the surface area is 34.54 to 326.54 mm. 2 The number and dimensions of the right circular cone cavities can be appropriately designed so that the cavity is equal to or larger than the length of the filter. In this case, the cavity is formed at the end of the filter on the side of the heated aroma generating unit in the longitudinal direction, but the cavity may be provided at the end opposite to this end.

[0122] FIG. 11 shows a right cylindrical aroma cartridge according to one embodiment of the present invention, in which a mouthpiece 221-7 is configured with a filter 2211 for filtering gas in which one cavity 221-7-c7 is formed, and a hollow space 221-7-v1 formed in a cartridge exterior body 24, in which a heated aroma generating unit 21 and a filter 2211 are adjacent to each other and joined and wrapped with the cartridge exterior body 24. 2-7 11 is a schematic diagram showing a cavity 221-7-c7 in the shape of a right cylinder, arranged from the end of the filter 2211 on the heated aroma generating unit 21 side in the longitudinal direction of the filter 2211, so that the central axes of the right cylinders of the filter 2211 and the cavity 221-7-c7 are substantially the same. In FIG. 11, the heated aroma generating unit and the filter are adjacent to each other, but this arrangement is not limited thereto, and conversely, the heated aroma generating unit and the cavity may be adjacent to each other. In this case, the length f of the filter is shortened, so that the amount of suction increases, and the number and size of the cavities formed in the filter, that is, the surface area, can be reduced. Note that the cartridge exterior body alone needs to have the strength required for a mouthpiece, so the thickness of the material of the cartridge exterior body, such as polyolefin resins such as PE and PP, PET resins, CA resins, polylactic acid (PLA), etc., and paper, etc., may be appropriately increased depending on the material.

[0123] FIG. 12 shows an embodiment of the present invention in which a mouthpiece 221-8, which is composed of a filter 2212 for filtering gas in which four cavities 221-8-c8 are formed and a cavity 221-8-v2 formed in the exterior body of the cartridge, is attached to a right cylindrical aroma cartridge in which the heated aroma generating unit 21 and the filter 2212 are adjacent to each other. 2-811, in which cavity 221-8-c8 is a right circular cylinder and is disposed in filter 21212 from the end of filter 2212 on the heated aroma-generating substance 21 side in the longitudinal direction of filter 2212 at a position rotationally symmetrical about the central axis of the right circular cylinder in the longitudinal direction of filter 2212. In this case, as in the explanation of Fig. 11, the heated aroma-generating substance and the cavity may be adjacent to each other, and the length f of the filter is shortened and the amount of suction is increased, so that the number and size of the cavities formed in the filter, i.e., the surface area, can be reduced. The strength of the cartridge exterior body is also the same as in Fig. 11.

[0124] A filter having such a cavity is also extremely effective as a means for optimizing suction to solve the problem of reduced suction volume caused by a mouthpiece having a conventional general support member and / or cooling member.

[0125] Fig. 13 is a schematic diagram showing an aroma cartridge 2-9 according to one embodiment of the present invention. The mouthpiece 222 includes a cylindrical support member 2221 for preventing the heated aroma generating body 21 from moving toward the mouthpiece 222, and a filter 2222 for filtering gas in which one cavity 2222-c1 adjacent thereto is formed. The mouthpiece 222 is adjacent to the heated aroma generating body 21, and these are joined and wound with a cartridge exterior body 24. The cavity 2222-c1 is disposed in the filter 2222 from the end of the filter 2222 on the support member 2221 side in the longitudinal direction, so that the center axes of the right cylinders of the filter 2222 and the cavity 2222-c1 are approximately the same. In this case, the number, size, and shape of the cavities are not limited to those shown in Fig. 13, and those described in the description of Figs. 6 to 10 can be applied. However, since the support member is approximately hollow, the number and size of the cavities can be significantly reduced.

[0126] 14 is a schematic diagram showing an aroma cartridge 2-10 according to one embodiment of the present invention. The mouthpiece 223 includes a cylindrical support member 2231 for preventing the adjacent heated aroma generating body 21 from moving toward the mouthpiece 223, a cylindrical cooling member 2232 for cooling the components volatilized by heating the heated aroma generating body 21 adjacent to the support member, and a filter 2223 having one cavity 2223-c1 adjacent to the cooling member 2232 for filtering gas. The mouthpiece 223 is adjacent to the heated aroma generating body 21, and is joined and wound with the cartridge exterior body 23. The cavity 2223-c1 is disposed in the filter 2223 from the end of the filter 2223 on the cooling member 2232 side in the longitudinal direction so that the center axes of the right cylinders of the filter 2223 and the cavity 2223-c1 are substantially the same. In this case as well, the number, size, and shape of the cavities are not limited to those shown in FIG. 14, and those described in the description of FIGS. 6 to 10 can also be applied.

[0127] Fig. 15 is a schematic diagram showing an aroma cartridge 2-11 according to one embodiment of the present invention. A mouthpiece 224 including a cylindrical cooling member 2241 for cooling components volatilized by heating the adjacent heated aroma generating body 21 and a filter 2242 having one cavity 2242-c1 adjacent to the cooling member 2241 for filtering gas is adjacent to the heated aroma generating body 21, and these are joined and wound with a cartridge exterior body 23. The cavity 2242-c1 is disposed in the filter 2242 from the end of the filter 2242 on the cooling member 2241 side in the longitudinal direction so that the center axes of the right cylinders of the filter 2242 and the cavity 2242-c1 are approximately the same. In this case, the number, size, and shape of the cavities are not limited to those shown in Fig. 15, and those described in Figs. 6 to 10 can also be applied, and can be appropriately designed according to the structure of the cooling member.

[0128] Next, as described in the explanation of Figures 13 and 14, the present invention will specifically explain the solution to the problem of deformation of the mouthpiece when a filter and a support member and / or a cooling member are provided in the mouthpiece and the length of the support member is increased to increase the amount of inhalation. Here, the shape reinforcing member of the mouthpiece serves as the inhalation optimization means to prevent the mouthpiece from deforming and thereby resolve the decrease in the amount of gas inhaled.

[0129] 16 is a schematic diagram showing an aroma cartridge 2-12 according to an embodiment of the present invention that prevents deformation of the mouthpiece. The mouthpiece 225-1 includes a support member 2251-1 that prevents the adjacent heated aroma generating body 21 from moving toward the mouthpiece 225-1, and a filter 2252-1 that filters gas adjacent to the support member 2251-1. The mouthpiece 225-1 is adjacent to the heated aroma generating body 21, and these are joined and wound with the cartridge exterior body 23. The suction optimization means in this case is one plate-shaped reinforcing member 2252-1-s1 that contacts the inner wall of the through hole 2251-1-h, and is fixedly or movably arranged in the through hole 2251-1-h that is formed so that the central axis of the support member 2251-1 and the central axis of the right circular cylinder are approximately the same, with the central axis being in the plane. By supporting the support member from the inside of the through hole with the plate-shaped reinforcing member in this way, deformation of the support member is prevented, and a decrease in the amount of suction can be prevented. This plate-shaped reinforcing material may be fixed with adhesive, for example, by forming a groove in the through hole, or it may simply be inserted into the through hole so that it can move, but is not limited to this method.

[0130] 17 is a schematic diagram showing an aroma cartridge 2-13 according to an embodiment of the present invention that prevents deformation of the mouthpiece. The mouthpiece 225-2 includes a support member 2251-2 that prevents the adjacent heated aroma generating body 21 from moving toward the mouthpiece 225-2 and a filter 2252-2 that is adjacent to the support member 2251-2 and filters gas. The mouthpiece 225-2 is adjacent to the heated aroma generating body 21, and these are joined and wrapped with a cartridge exterior body. The suction optimization means is a plate-shaped reinforcing member 2251-2-s2 that is included in the reinforcing support member 225-2 and is formed by intersecting two plate-shaped members that contact the inner wall of the through hole 2251-2-h. The plate-shaped reinforcing member 2251-2-s2 has its central axis in a plane and is fixedly or movably disposed in the through hole 2251-2-h that is formed so that the central axis of the support member 2251-2 and the central axis of the right circular cylinder are substantially the same. This plate-shaped reinforcing material can prevent deformation more strongly than the plate-shaped reinforcing material shown in Fig. 16, so it is possible to make the length of the support member longer and prevent a decrease in the suction amount. As a method of fixed or movable arrangement, for example, the method explained in Fig. 16 can be applied as it is, but is not limited thereto.

[0131] 18 is a schematic diagram showing an aroma cartridge 2-14 according to one embodiment of the present invention for preventing deformation of the mouthpiece. The mouthpiece 225-3 includes a support member 2251-3 for preventing the adjacent heated aroma generating body 21 from moving toward the mouthpiece 225-3 and a filter 2252-3 for filtering gas adjacent to the support member 2251-3, and is adjacent to the heated aroma generating body 21, and these are joined and wound with the cartridge exterior body 23. The suction optimization means is a shape reinforcement member including a tubular reinforcement member 2251-3-s4 and four plate-shaped reinforcements 2251-3-s3 that are fixedly or movably arranged as the reinforcing support member 2251-3. The tubular reinforcement 2251-3-s4 is a concentric tube having a radius smaller than the radius of the through hole 2251-3-h having the same axis as the through hole 2251-3-h of the support member 2251-3, which is formed so that the central axis of the support member 2251-3 and the right circular cylinder are substantially the same. In addition, the four plate-like reinforcement members 2251-3-s3 are formed so as to contact the inner wall of the through hole 2251-3-h on the outer circumferential side and in the radial direction of the tubular reinforcement member 2251-3-s4. This shape reinforcement member consisting of the tubular reinforcement member and the plate-like reinforcement member has a greater reinforcing effect than the plate-like reinforcement member shown in FIG. 17, and can further increase the length of the support member. In this case, the fixed or movably arranged method is the same as that of FIG. 16.

[0132] Figure 19 is a schematic diagram showing an aroma cartridge 2-15 that uses a columnar reinforcement member 2251-4-s4 that is a solid (not hollow) concentric cylinder instead of the tubular reinforcement member 2251-3-s4 that was a concentric tube in Figure 18. Whether a hollow circular tube or a solid cylinder is used can be appropriately changed depending on the balance between the reinforcing effect and the amount of suction.

[0133] The reinforcing support members of Figs. 16 to 19 can form a mouthpiece together with the filter having a cavity formed therein as described with reference to Figs. 5 to 10, and further, a cooling member can also be connected to form a mouthpiece.

[0134] Fig. 20 is a schematic diagram showing an aroma cartridge 2-15, and shows an example of an aroma cartridge in which a mouthpiece, which is made by connecting the reinforcing support member of Figs. 16 to 19 and the filter with a cavity formed therein described in Figs. 5 to 10, is joined adjacent to the heated aroma medium. This shows that the mouthpiece 225-5 is adjacent to the heated aroma medium 21, and is equipped with the reinforcing support member 2251-5 provided with shape reinforcing members 2251-3-s3 and 2251-3-s4 that prevent the adjacent heated aroma generating body 21 from moving toward the mouthpiece 225-5, and the filter 2252-5 adjacent to the reinforcing member 2251-3-s3 and 2251-3-s4 that prevents the adjacent heated aroma generating body 21 from moving toward the mouthpiece 225-5, and the filter 2252-5 with one cavity formed therein for filtering gas is joined and wrapped around the cartridge exterior body 23.

[0135] The cavity 2252-5-c1 is disposed in the filter 2252-5 at the end of the filter 2252-5 on the heated aroma generating unit 21 side in the longitudinal direction thereof, such that the center axes of the right circular cylinders of the filter 2252-5 and the cavity 2252-5-c1 are substantially aligned. The suction optimization means here is a shape reinforcement having a tubular reinforcement 2251-5-s4 of a hollow concentric tube having a radius smaller than the radius of the through hole 2251-5-h having an axis substantially identical to the axis of the support member 2251-5-h of the support member 2251-5 formed so that the central axis of the support member 2251-5 and the right circular cylinder are substantially identical, and four plate-like reinforcements 2251-5-s3 formed so as to contact the inner wall of the through hole 2251-5-h in the radial direction of the tubular reinforcement 2251-5-s4 on the outer periphery side of the tubular reinforcement 2251-5-s4, and is fixedly or movably arranged as the reinforcing support member 2251-5. It is not limited to such a configuration, and it is possible to combine various reinforcing support members and filters formed with various cavities.

[0136] Fig. 21 is a schematic diagram showing an aroma cartridge 2-15, and shows an example of an aroma cartridge in which a mouthpiece having a cooling member interposed between the reinforcing support member of Figs. 16 to 19 and the filter having a cavity formed therein described in Figs. 5 to 10 is connected to a heated aroma body. The mouthpiece 226 includes a reinforcing support member 2261 having shape reinforcements 2261-s3 and 2261-s4 for preventing the adjacent heated aroma generating member 21 from moving toward the mouthpiece 226, a cooling member 2262 for cooling gas from the heated aroma generating member 21, and a filter 2263 having one cavity 2263-c1 formed adjacent to the cooling member 2262 for filtering gas. The mouthpiece 226 is adjacent to the heated aroma body 21, and these are joined and wrapped with a cartridge exterior body 23.

[0137] The cavity 2263-c1 is disposed at the end of the filter 2263 on the heated aroma generating unit 21 side in the longitudinal direction of the filter 2263 so that the central axes of the right circular cylinders of the filter 2263 and the cavity 2263-c1 are substantially identical. The suction optimization means here is a shape reinforcement having a tubular reinforcement 2261-s4 of a hollow concentric tube having a radius smaller than the radius of the through hole 2261-h having substantially the same axis as the axis of the through hole 2261-h of the support member 2261 formed so that the central axis of the support member 2261 and the central axis of the right circular cylinder are substantially identical, and four plate-like reinforcements 2261-s3 formed so as to contact the inner wall of the through hole 2261-h in the radial direction of the tubular reinforcement 2261-s4 on the outer periphery side of the tubular reinforcement 2261-s4, and is disposed fixedly or movably as the reinforcing support member 2261. In this case, too, the present invention is not limited to such a configuration, and it is possible to combine various reinforcing support members and filters having various cavities formed therein with cooling members interposed therebetween.

[0138] As described above, as the amount of inhalation increases due to improvements in the filter and support member, the heat of the gas is more likely to be transferred by convection from the heating element to the filter, which weakens the bonding strength between the components that make up the aroma cartridge, causing gas to leak from between the components and adversely affecting the amount of inhalation. Below, we provide an aroma cartridge that solves this problem by providing a heat insulating member between the heated aroma generating element and the mouthpiece.

[0139] 22 is a schematic diagram showing an aroma cartridge 2-18 according to one embodiment of the present invention. The suction optimization means here has a heat insulating member 2271. A mouthpiece 227 equipped with a heat insulating member 2271 adjacent to the heated aroma generating unit 21 and a filter 2272 adjacent to the heat insulating member 2271 for filtering gas is adjacent to the mouthpiece 227, and is adjacent to the heated aroma generating unit 21, and these are joined and wrapped with a cartridge exterior body 23.

[0140] 23 is a schematic diagram showing an aroma cartridge 2-19 according to one embodiment of the present invention. Here too, the suction optimization means has a heat insulating member 2281. A mouthpiece 228 including a heat insulating member 2281 adjacent to the heated aroma generating unit 21, a cylindrical cooling member 2282 adjacent to the heat insulating member 2281 for cooling gas from the heated aroma generating unit 21, and a filter 2283 adjacent to the cooling member 2282 for filtering gas is located adjacent to the heated aroma generating unit 21, and is joined and wrapped around the cartridge exterior body 23.

[0141] These heat insulating members are preferably plastic heat insulating porous bodies such as sponges with long continuous pores and a long flow path, rather than dispersing high temperature gas throughout like the support members adjacent to the heated aroma body, and have a function of cooling by retaining the gas to some extent, but do not require a cooling function up to the cooling member, and are preferably used in place of a support member that prevents the heated aroma generating body from moving towards the mouthpiece.The length s of the heat insulating member therefore depends on the material used, but a length of about 1 to 5 mm is sufficient.

[0142] Next, with reference to the drawings, we will explain the lid material and partition material, which function as suction optimization means to prevent an extreme decrease in suction volume caused by clogging of gaps in the filter and cooling member due to fallen non-tobacco material and dust.

[0143] Fig. 24 is a partial schematic diagram of a heated aroma generating body of an aroma cartridge according to one embodiment of the present invention. The suction optimization means here includes a lid material 211 arranged on the aroma cartridge end side of both ends of the heated aroma generating body, and a partition material 212 arranged on the other end side of the heated aroma generating body. As the lid material 211 and the partition material 212, a material such as a very thinly sliced ​​filter-like material, a nonwoven fabric, or a mesh that does not reduce the amount of gas suction is preferably used, and they may be fixed to the heated aroma generating body 21 with an adhesive or the like.

[0144] Depending on the state of the heated aroma-generating base material and the heated aroma-generating body that bundles them, either one or both of the lid material and partition material may be provided. The lid material and / or partition material prevent clogging of the filter and / or cooling member due to fallen objects and dust, and ensure a stable amount of suction. It is also possible to prevent the generation of fallen objects and dust that occurs when the aroma cartridge is inserted into the needle-shaped heating element.

[0145] The above describes in detail, with reference to the drawings, the physical solution for structural improvement to ensure the amount of gas inhaled when smoking an aroma cartridge. Below, the gas generation-sustaining material provided in the heated aroma generating body, which solves the problem of the decrease in the amount of gas inhaled, is described with reference to the drawings. Conventional heated aroma generating bodies have a problem in that the amount of gas released decreases over time, resulting in a decrease in the amount of gas inhaled when smoking. The aroma cartridge of the present invention includes a heated aroma generating substrate that constitutes the heated aroma generating body and is treated with a chemical solution, as a gas generation-sustaining material that prevents a decrease in the amount of gas inhaled.

[0146] First, Figure 25 shows a schematic diagram (A) of a heated aroma-generating sheet that constitutes a heated aroma-generating body according to one embodiment of the present invention, and a schematic diagram (B) of a heated aroma-generating filling that constitutes a heated aroma-generating body according to one embodiment of the present invention.

[0147] The heated aroma-generating substrate is manufactured by various manufacturing processes [means], but is ultimately wound as a sheet or filler to become the heated aroma-generating substrate. As shown in Figures 2 and 3, 11 ya(2) 12 The longitudinal direction of the heated smoking tool corresponds to the length z direction, and the heated aroma-generating material is cut to the length z according to the heated smoking tool, but has an appropriate width w and thickness y as a gas generation sustaining material. Here, as an example, FIG. 25 is used to show the dimensions corresponding to the heated aroma-generating material described in FIG. 5. The longitudinal direction of the aroma cartridge corresponds to the length z direction, and the heated aroma-generating material is formed by wrapping the heated aroma-generating base material in paper in this direction. The heated aroma-generating sheet (A) contained in the heated aroma-generating material preferably has a length z of 12 mm, a width w and a thickness y in the range of 60 to 90 mm and 0.1 to 1.0 mm, respectively, of the heated smoking tool. The heated aroma-generating filler (B) has a length z of 12 mm, but a width x and a thickness y of 1.0 to 2.0 mm and a thickness of 0.1 to 1.0 mm, respectively. The heated aroma-generating filler is obtained by further cutting the heated aroma-generating sheet.

[0148] Fig. 26(A-1) shows a heated aroma-generating body in which one heated aroma-generating sheet in Fig. 25(A) is folded and wrapped in heated aroma-generating body inner material 21-p, and Fig. 26(A-2) shows a heated aroma-generating body in which one heated aroma-generating sheet in Fig. 25(A) is rolled up and wrapped in heated aroma-generating body inner material 21-p. Fig. 26(B) shows a heated aroma-generating body in which 50 heated aroma-generating fillers are wrapped in heated aroma-generating body inner material 21-p. The outer diameters of these are also the same as those of the heated smoking device (1) 11 ya(2) 12 The filling rate is set appropriately depending on the type of the heated aroma-generating material, but if it is set to 6.9 mm, which corresponds to the heated aroma-generating material described in Figure 5, the filling rate will be within a range of 60 to 90%. In particular, when the filling rate is 60 to 73%, severe fusion over time has not been observed in the heated aroma-generating base material. This filling rate is adjusted by the width w of the heated aroma-generating sheet and the number of heated aroma-generating fillers, and does not apply when a gas generation-sustaining material is present.

[0149] The gas generation-sustaining material, i.e., the heated aroma-generating substrate treated with a chemical solution, which has the function of preventing a decrease in the amount of gas released from a heated aroma-generating body, which is closely related to a decrease in the amount of gas absorbed during smoking, and ensuring the amount of gas absorbed, will be specifically described below with reference to the drawings. The aroma cartridge of the present invention comprises a heated aroma-generating body and the heated aroma-generating substrate treated with a chemical solution as a gas generation-sustaining material.

[0150] There are various methods [apparatuses] for manufacturing conventional heated aroma-generating substrates, one example of which is shown in Fig. 33. The substrate is manufactured by a process [means] of preparing a non-tobacco material by drying and grinding the non-tobacco material and then dry-mixing it, a process [means] of preparing materials selected from aerosol formers, binders, anti-adhesive agents, flavorings, non-tobacco material extracts, antibacterial preservatives, etc., a process [means] of preparing pure water and alcohol, a wet-mixing process [means] of mixing all of these prepared materials together, a papermaking process [means] of producing a water-containing sheet from the slurry produced by the wet mixing, a molding process [means] of compressing or casting the paper-made water-containing sheet to produce a sheet, a process [means] of drying the sheet produced in the molding process [means], and a sheet processing process [means] of cutting or folding the dried heated aroma-generating sheet.

[0151] As a specific example, Production Example 1 is shown.

[0152] (Production Example 1) The following ground materials were added to the dry mixer as non-tobacco materials and dry mixed for 5 minutes. Dried and ground black tea leaves 100 parts by weight 20 parts by weight of dried and ground liquorice Dried and crushed lotus leaves 10 parts by weight

[0153] The above dry mixture and the following materials were added to a wet mixer and wet mixed for 15 minutes. Polypropylene glycol 25 parts by weight Glycerin 25 parts by weight Carboxymethylcellulose sodium salt 5 parts by weight Menthol 3 parts by weight Ethanol 3 parts by weight Pure water 200 parts by mass

[0154] In the process [means] of forming a sheet from the slurry thus obtained, a specified amount of the slurry was poured into a frame equipped with an appropriate rack to produce a water-containing sheet. In this manufacturing example, the water content of the water-containing sheet at this time is approximately 95% when the water content of the slurry is taken as 100%.

[0155] Subsequently, the above-mentioned water-containing sheet was passed three times through a press roll having a predetermined clearance to be molded, and then, 7 parts by mass of pure water per 100 parts by mass of the water-containing sheet that had been passed three times was added to the above-mentioned water-containing sheet, and the sheet was passed through the above-mentioned press roll another five times.

[0156] Furthermore, the formed moisture-containing sheet obtained as described above was dried for 300 minutes in an environment of 35°C to prepare a heated aroma-generating sheet with a moisture content of 20% by mass. The drying temperature is preferably less than 50°C in order to maintain the flavor. More preferably, it is less than 45°C, and even more preferably, it is less than 40°C. The thickness of the sheet is appropriately adjusted, but in this manufacturing example, the thickness was 0.5 mm. This sheet was cut into a rectangular heated aroma-generating sheet having a length of 240 mm x width of 75 mm, and a heated aroma-generating filling having a length of 240 mm x width of 1.5 mm. The length direction of the sheet and filling cut from the heated aroma-generating sheet was parallel to the rotation axis of the roll, and the width direction was the rotation direction of the roll.

[0157] One heated aroma-generating sheet and 50 heated aroma-generating fillers thus prepared were each wound and then cut to a length of 12 mm to produce the heated aroma-generating bodies as shown in Figures 26(A-1) and 26(B). An aroma cartridge of the type shown in Figure 13 was then produced in which the heated aroma-generating body is joined to a mouthpiece equipped with a support member and filter. The support member was a PE tube with a cylinder of outer diameter 6.9 mm and a through hole of inner diameter 4.0 mm. The filter was made of acetyl cellulose fibre formed into a cylindrical shape with a basis weight of 34 g / m2.2 The cartridge exterior was wrapped in paper with a length of 23 mm and had a basis weight of 38 g / m 2 The cartridge exterior was made of paper with a grammage of 32 to 45 g / m2, wrapped around two and a half times so that the inner diameter was 6.9 mm, and glued. 2 When a paper cylinder formed by wrapping the paper around it two and a half times is used, it becomes suitable as an aroma cartridge in which the heated aroma generating unit is inserted into the heating element of a heated smoking device. Then, a support member and a filter are inserted into one end of the cartridge exterior body to form a mouthpiece, and the heated aroma generating unit is inserted into the other end, and then a paper cylinder with a basis weight of 40 g / m is inserted so as to overlap the mouthpiece. 2 However, in order to clarify the effect of the manufacturing method [apparatus] on the heated aroma-generating substrate, i.e., the difference in the function of the gas generation sustaining material, a filter without a cavity, which is a suction optimization means, was used.

[0158] The heated aroma generating units and aroma cartridges thus produced were evaluated as follows.

[0159] <Evaluation 1> The prepared aroma cartridge was packed in a paper box with a long side of 70 mm, a short side of 14 mm, and a height of 45 mm, with the heated aroma generating body facing the bottom. The prepared box containing the aroma cartridge was placed in a plastic bag and left in an environment of 40°C for two weeks. After that, it was taken out and left in an environment of normal temperature and humidity for one day, and the following evaluation was performed. The filling material was removed from the heated aroma generating body, and it was confirmed whether it had solidified. At the same time, five subjects smoked, and a sensory evaluation of the amount of inhalation and flavor was performed. Rank A: The item falls apart when removed with tweezers. The amount of inhalation and flavor should be sufficient for four or more people to enjoy. Rank B: Can be loosened by pressing with tweezers The amount of inhalation and flavor can be fully felt by two or more people. Rank C: Lumps remain even when pressed with tweezers No one can fully detect the amount of inhalation or the flavor. Rank C items are likely to become difficult to insert into the heating element of a heated smoking device due to long-term storage, etc.

[0160] The aroma cartridge produced in (Manufacturing Example 1) was rated as rank C, and the heated aroma-generating sheet and the heated aroma filling fused together over time, reducing the amount of gas released when smoking, i.e., the amount of gas inhaled, and also changing the flavor, so that they did not function as gas-generation-sustaining materials for the heated aroma.

[0161] This problem was solved by improving the manufacturing method [apparatus]. This manufacturing method [apparatus] is characterized by the introduction of a second wet mixing step [means] as a manufacturing process [means], as shown in Figure 27. As is clear from the figure, the method includes a dry mixing step [means] Z1 for mixing dried and ground non-tobacco material, a first wet mixing step [means] M2 for mixing the non-tobacco material produced in the dry mixing step [means] and a material selected from an aerosol former, a binder or thickener, cross-linked PVP, a flavoring, a non-tobacco extract, β-cyclodextrin, microcrystalline cellulose, and an antibacterial preservative into an alcohol and pure water mixture, and a second wet mixing step M3 for mixing the alcohol and pure water mixture containing the non-tobacco material, etc. produced by the first wet mixing step [means] with pure water and / or alcohol. The heated aroma-generating substrate is produced through a second wet mixing process [means] M3 in which coal is further added to produce a slurry containing non-tobacco materials, etc., a papermaking process [means] S1 in which a moisture-containing sheet is produced from the slurry produced in the second wet mixing process [means], a sheet forming process [means] S2 in which the moisture-containing sheet is compressed and processed into a sheet, a drying process [means] S3 in which the sheet produced in the sheet forming process [means] is dried to produce a heated aroma-generating sheet, and a sheet processing process [means] H1 in which the heated aroma-generating sheet is cut or folded.

[0162] As a specific example, Production Example 2 is shown.

[0163] (Production Example 2) Black tea leaves are dried at 70°C to a moisture content of 2% by mass, and then crushed. Similarly, liquorice, lotus leaves, and ginseng from the legume family are dried and crushed. The drying temperature is preferably 60°C to 80°C or lower. Within this range, it is easy to reach the desired moisture content while avoiding the dissipation of the required flavor components. If the temperature is 65°C or higher, it is even easier to reach the desired moisture content, and if the temperature is 75°C or lower, it is even easier to prevent the dissipation of the required aroma components.

[0164] The moisture content after pulverization is preferably 5% by mass or less. This makes it easier to make a slurry in the subsequent step [means]. It is more preferable that the moisture content is 3% by mass or less. It is also preferable that the moisture content is 0.1% by mass or more, since it is possible to maintain a good affinity with water, etc.

[0165] The dried and ground material passed through an 80-mesh sieve was used as the non-tobacco material, and was placed in a dry mixer in the amounts shown below and dry mixed for 5 minutes. Dried and ground black tea leaves 100 parts by weight 20 parts by weight of dried and ground liquorice Dried and crushed lotus leaves 10 parts by weight Dried and ground Korean ginseng 5 parts by weight

[0166] The above dry mixture and the following materials were added to a wet mixer, and the first wet mixing was carried out for 15 minutes. Polypropylene glycol 30 parts by weight Glycerin 20 parts by weight Carboxymethylcellulose sodium salt 5 parts by weight Menthol 3 parts by weight Ethanol 3 parts by weight Pure water 20 parts by mass

[0167] Next, 180 parts by mass of pure water and 10 parts by mass of ethanol are added to the wet mixer containing the slurry, and a second wet mixing is performed for 10 minutes. The reason for adding ethanol here is that it can greatly improve the dispersion state of the dried and pulverized material relative to polypropylene glycol and glycerin. The alcohol is not limited to ethanol as long as it is a lower monoalcohol. The amount of such a lower monoalcohol added is preferably 0.1 to 10 parts by mass relative to 100 parts by mass of the dried and pulverized material. When the amount is 0.1 part by mass or more, the above-mentioned dispersion state is improved, and when the amount is 10 parts by mass or less, the remaining lower monoalcohol can be suppressed. When the amount is 0.5 to 5 parts by mass, this effect is more remarkable.

[0168] The reason for adding pure water first to form the mixture is that the mixture is dispersed first, and then additional water is added to dilute and mix to obtain a slurry with good dispersibility. It is also preferable to add water in multiple batches. When adding water in multiple batches, it is preferable to combine a small amount of water added earlier and a large amount of water added later. In this way, the degree of improvement in dispersibility is high when water is added earlier, and a uniform slurry is obtained by adding a large amount of water later.

[0169] In the process [means] of forming a sheet from the slurry obtained as described above, a specified amount of the slurry was poured into a frame equipped with an appropriate rack to produce a water-containing sheet. In this embodiment, the water content of the water-containing sheet is approximately 95% when the water content of the slurry is 100%.

[0170] Subsequently, the above-mentioned water-containing sheet is passed three times through a press roll having a predetermined clearance to be molded, and then water is added to the water-containing sheet after passing it three times in an amount equivalent to 7 parts by mass per 100 parts by mass of the water-containing sheet, and the sheet is passed through the press roll five times. Preferably, the amount of water is 2 to 15 parts by mass per 100 parts by mass of the water-containing sheet. In this way, when the water-containing sheet is molded multiple times, adding water in the middle of the process has the effect of easily regulating the amount of water contained in the water-containing sheet within a certain range, and has the effect of regulating the conditions for the subsequent drying step [means] and the effect of regulating the quality of the final product.

[0171] Furthermore, the formed moisture-containing sheet obtained as described above was dried for 300 minutes in an environment of 35°C to prepare a formed sheet for electronic cigarette filling with a moisture content of 20% by mass. The drying temperature is preferably less than 50°C to maintain the flavor. More preferably, it is less than 45°C, and even more preferably, it is less than 40°C. The thickness of the sheet was 0.5 mm. This sheet was cut into a heated aroma-generating sheet with a length z of 240 mm and a width x of 75 mm, and a heated aroma-generating filling with a length z of 240 mm and a width x of 1.5 mm to be wrapped as a heated aroma-generating body.

[0172] One heated aroma-generating sheet and 50 heated aroma-generating fillers manufactured by this method [apparatus] were each wound and then cut to a length z of 12 mm to produce heated aroma-generating bodies as shown in Figures 26(A-1) and 26(B). Then, as in (Manufacturing Example 1), an aroma cartridge was manufactured in which the heated aroma-generating body is joined to a mouthpiece equipped with a support member and a filter as shown in Figure 13. However, in order to clarify the effect of the manufacturing method [apparatus] on the heated aroma-generating substrate, i.e., the difference in the function of the gas generation-sustaining material, a filter without a cavity (suction optimization means) was used.

[0173] Then, in the same way as the aroma cartridge produced in (Production Example 1), <Evaluation 1> was carried out, and a result of rank A was obtained. This is thought to mean that the heated aroma-generating substrate produced by this method [apparatus] has less fusion over time inside the heated aroma-generating substrate and between other substrates, and there is less change in the amount of gas released due to heating, so that the amount of gas inhaled during smoking is maintained. In other words, the heated aroma-generating substrate produced by this method [apparatus] functions as a gas generation sustaining material for the heated aroma-generating substrate.

[0174] The manufacturing method [apparatus] shown in FIG. 27 has been improved as shown in FIG. 28. The manufacturing method [apparatus] shown in FIG. 28 is characterized in that, in the manufacturing method [apparatus] shown in FIG. 27, a step [means] S3 of adding an aerosol former is further added when the moisture content of the sheet becomes less than 50% in the sheet forming step [means] S2. Specifically, the amount of propylene glycol in the first wet mixing in (Manufacturing Example 2) was reduced by 10 parts by mass, and a 50% ethanol solution of propylene glycol was used and sprayed at a temperature of less than 40°C to absorb the propylene glycol into the sheet, thereby compensating for the propylene glycol reduced in the first wet mixing. Here, the concentration of the alcohol solution of the aerosol former is preferably in the range of 20 to 80% in terms of the absorbency of the aerosol former and the drying property of the alcohol. If the concentration is high, it is difficult to absorb, and if the concentration is low, it takes time to dry the alcohol. From the viewpoint of the aerosol former's absorbency, the absorption temperature is preferably 20 to 50° C. If the temperature is too high, the aerosol former will evaporate rapidly, and if the temperature is too low, it will become difficult to absorb.

[0175] Since the dispersion state in the second wet mixing was good, the absorption of propylene glycol in this step [means] was rapid. The heated aroma-generating substrate with a thickness of 0.5 mm produced by this method [apparatus] was also cut to the same size as in (Production Example 2) to prepare aroma cartridges, and when <Evaluation 1> was performed, the result was ranked A, making it clear that the heated aroma-generating sheet produced by this method [apparatus] also functions as a gas generation sustaining material for the heated aroma-generating substrate.

[0176] The common improvement of the manufacturing methods [apparatuses] in Figures 27 and 28 is that the mixing and dispersion of the non-tobacco material and the aerosol former are improved. In view of this, a manufacturing method [apparatus] that does not involve the mixing and dispersion process [means] of the non-tobacco material and the aerosol former has been found, resulting in the manufacturing process [means] of the heated aroma-generating substrate shown in Figure 29.

[0177] That is, the gas generation sustaining material is produced by a wet mixing process [means] M1 in which dried and ground non-tobacco material is mixed with pure water to produce a slurry of the non-tobacco material, a papermaking process [means] S1 in which a moisture-containing sheet is produced from the slurry produced in the wet mixing process [means], a sheet forming process [means] S2 in which the moisture-containing sheet is compressed or cast to be processed into a sheet, a drying process [means] S3 in which the moisture content of the sheet produced in the sheet forming process [means] is reduced to less than 50% by mass, and an aerosol former, a bonding agent, and the like are added to the sheet produced in the drying process [means]. The heated aroma-generating substrate is manufactured through an absorption and adsorption process [means] S4 in which a mixture of alcohol and pure water is applied to or soaked into a material selected from a material selected from a thickener, cross-linked PVP, flavoring, non-tobacco extract, β-cyclodextrin, microcrystalline cellulose, a concentrated solution of the water discharged in the sheet forming process [means], and an antibacterial preservative; a drying process [means] S5 in which the sheet manufactured in the absorption and adsorption process [means] is dried to manufacture a heated aroma-generating sheet; and a sheet processing process [means] H1 in which the heated aroma-generating sheet is cut or folded.

[0178] A specific example of this manufacturing method [apparatus] is shown in (Manufacturing Example 3).

[0179] (Production Example 3) Wood fiber 50 parts by weight 50 parts by mass of dried black tea leaves Water 5000 parts by mass The above was mixed to form a slurry.

[0180] The slurry was cast into a sheet having a thickness of 0.5 mm. The remaining water in the cast was concentrated and stored for use in the next step [means].

[0181] The sheet was dried and the weight per 100 parts by mass of the sheet was Polypropylene glycol 10 parts by weight Glycerin 20 parts by weight Carboxymethylcellulose sodium salt 2 parts by weight Menthol (50% ethanol solution) 3 parts by weight Concentrated cast residue water 50 parts by weight was added and dried to prepare a sheet.

[0182] The sheet produced was used to prepare a heated aroma generating unit and an aroma cartridge using the same, as in Manufacturing Example 2, and evaluation 1 was carried out. The result was ranked A, demonstrating that the heated aroma generating sheet produced by this method [apparatus] also functions as a gas generation sustaining material for the heated aroma generating base.

[0183] Previous manufacturing methods [apparatus] were characterized by producing a slurry of non-tobacco materials, etc., and then papermaking the slurry to produce a heated aroma-generating sheet, but as shown in Figure 29, a method [apparatus] in which an aerosol former, flavoring, binder, etc. are absorbed into a water-containing sheet produced by papermaking a slurry of only non-tobacco materials produced good results. As a result, it was thought that the process [means] of papermaking from a slurry of materials with various different properties was unreasonable, and a manufacturing method [apparatus] that did not require a papermaking process [means] was investigated, leading to the method [apparatus] shown in Figure 30. This method is characterized by applying large shearing and compressive forces, such as those of a three-roll machine, to a mixture of non-tobacco materials, etc.

[0184] That is, the method includes non-tobacco material preparation steps [means] Z1 and Z2 for drying and grinding non-tobacco materials, a flavor and / or non-tobacco extract dissolving step [means] M1 for mixing at least a flavor and / or a non-tobacco material extract with cross-linked PVP and / or β-cyclodextrin in alcohol to retain the flavor and / or non-tobacco extract in the cross-linked PVP and / or β-cyclodextrin, and an aerosol former dissolving step [means] M2 for mixing at least an aerosol former and a binder or thickener in pure water. The method (apparatus) for producing a heated aroma-generating substrate includes a wet mixing process (means) M3 for mixing the material produced in the non-tobacco material preparation process (means), the material produced in the flavoring and / or non-tobacco extract dissolving process (means), and the material produced in the aerosol former dissolving process (means), a sheet forming process (means) S1 for compressing the material produced in the wet mixing process (means) to produce a heated aroma-generating sheet, and a sheet processing process (means) H1 for cutting or folding the heated aroma-generating sheet.

[0185] A specific example of this manufacturing method [apparatus] is shown in (Manufacturing Example 4).

[0186] (Production Example 4) In the non-tobacco material preparation steps [means] Z1 and 2 for drying and grinding the non-tobacco material, black tea leaves are used as the non-tobacco material, which is dried in an oven at 70°C, then ground using an agitator grinder and passed through an 80 mesh sieve to prepare a non-tobacco material with a moisture content of 2% by mass.

[0187] In the step M1 of dissolving menthol, menthol, a lower alcohol, and a water-insoluble crosslinked polymer are weighed and mixed to dissolve menthol. It is preferable to dissolve menthol in a lower alcohol, and then add and mix the water-insoluble crosslinked polymer. By mixing menthol, a lower alcohol, and a water-insoluble crosslinked polymer, the effect of suppressing dissipation of menthol can be obtained.

[0188] Here, the menthol is not limited to that obtained from natural products, but may be a synthetic product, or may be peppermint, mint, peppermint oil, or other material containing menthol.

[0189] The lower alcohol is a solvent that dissolves menthol, and ethyl alcohol is particularly preferably used.

[0190] The water-insoluble crosslinked polymer is intended to be a polymer that is water-soluble and crosslinked, and becomes insoluble in water and swells. Of course, it is preferable that the polymer does not dissolve in lower alcohol and swells, and such a polymer is selected. Such a water-insoluble crosslinked polymer has a hydrophilic portion and a hydrophobic portion, and it is considered that the hydrophilic portion contributes to swelling, and the hydrophilic portion is oriented toward menthol, thereby suppressing the dissipation of menthol. Preferred examples of hydrophilic crosslinked polymers include crosslinked PVP and crosslinked polysaccharides that are made water-insoluble by epoxy crosslinking, ester crosslinking, or ether crosslinking of water-soluble polysaccharides. In particular, when ethanol and crosslinked PVP are used together with menthol, the effect of significantly suppressing the dissipation of menthol was observed.

[0191] Menthol may be added in an amount that achieves the desired flavor, but the menthol content in the heated aroma-generating base material is preferably 0.1 to 10 mass, and more preferably 0.2 to 5 mass.

[0192] In forming the heated aroma-generating base material, the amount of hydrophilic crosslinked polymer added is preferably 10 to 2000 parts by mass, and more preferably 50 to 600 parts by mass, per 100 parts by mass of menthol.

[0193] In order to achieve the effect of suppressing the dissipation of menthol, the hydrophilic crosslinked polymer is preferably present in the heated aroma-generating substrate at 2% by mass or more, more preferably at 4% by mass or more. By having such an amount present, it is possible to store the substrate for a long time while suppressing the dissipation of menthol, and the refreshing feeling of menthol can be enjoyed even after long-term storage. In addition, the content of the hydrophilic crosslinked polymer in the heated aroma-generating substrate is preferably 20% by mass or less, more preferably 10% by mass or less. If it is 10% by mass or less, it is possible to maintain the flavor caused by non-plant-derived polyphenols, etc.

[0194] The amount of the lower alcohol used is preferably 50 parts by mass or more relative to 100 parts by mass of menthol. Furthermore, when the amount is 100 parts by mass or more, the hydrophilic crosslinked polymer can be sufficiently mixed while dissolving the menthol. When the amount is 2000 parts by mass or less, the amount of the lower alcohol remaining in the subsequent process [means] can be reduced, and an efficient production process [means] can be achieved.

[0195] From the above, as an example, Menthol 100 parts by weight Ethyl alcohol 200 parts by weight Polyvinyl polypyrrolidone 200 parts by weight The amount of menthol was weighed, and the menthol was dissolved in ethyl alcohol to obtain a menthol ethyl alcohol solution. The crosslinked PVP was then added to the menthol ethyl alcohol solution and mixed by stirring to obtain a menthol / ethyl alcohol / crosslinked PVP mixture.

[0196] Next, in the step M2 of dissolving materials such as an aerosol former, the aerosol former, flavor additives, preservatives, binders, thickeners, etc. are dissolved in pure water.

[0197] Here, as the aerosol former, glycerin, propylene glycol, sorbitol, triethylene glycol, lactic acid, diacetin (glycerin diacetate), triacetin (glycerin triacetate), triethylene glycol diacetate, triethyl citrate, isopropyl myristate, methyl stearate, dimethyl dodecanedione, dimethyl tetradecanedione, etc. can be used. In particular, glycerin and propylene glycol are preferably used. These are preferably used in an amount of 1 to 80% by mass, more preferably 10 to 40% by mass, based on the heated aroma-generating substrate.

[0198] Flavoring agents for adding flavor are used as necessary, and examples thereof include extracts of peppermint, cocoa, coffee, black tea, etc.

[0199] If necessary, antibacterial food preservatives can be added, such as sorbic acid, potassium sorbate, benzoic acid, and sodium benzoate.

[0200] Examples of binders or thickeners that can be used include gums such as guar gum, xanthan gum, gum arabic, and locust bean gum, modified cellulose polymers such as hydroxypropyl cellulose, carboxymethyl cellulose, hydroxyethyl cellulose, methyl cellulose, and ethyl cellulose, polysaccharides such as organic acids such as starch, alginic acid, and conjugate base salts of organic acids such as sodium alginate, sodium carboxymethyl cellulose, caranagin, agar, and pectin, and combinations of these may also be used.

[0201] Of these, 20% aqueous solutions of glycerin, propylene glycol, sodium carboxymethylcellulose, methylcellulose, glucomannan, and xylitol were prepared.

[0202] Next, in step M3 of wet-mixing the materials from each step [means] of the non-tobacco material preparation steps [means] Z1 and 2, the flavor dissolving step [means] M1, and the aerosol former dissolving step [means] M2, a conventional wet mixer was used to mix the materials in the following formulation for 15 minutes while applying shear force with a mixing blade, to prepare a composition for a heated aroma-generating substrate from a non-tobacco plant. Dried and ground black tea leaves 100 parts by weight Menthol / Ethyl alcohol / Crosslinked PVP 25 parts by weight Glycerin 30 parts by weight Propylene glycol 30 parts by weight Sodium carboxymethylcellulose 4 parts by weight Methylcellulose 15 parts by weight Xylitol aqueous solution 8 parts by weight Glucomannan 1 part by weight

[0203] In the step [means] S1 of forming a sheet, a three-roll mill was used. The above composition was put into the three-roll mill, 20 parts by mass of pure water was added while observing the state of the sheet, and a doctor blade was pressed against the roll to obtain a sheet-like material. This step [means] was repeated eight times to obtain the final sheet-like non-tobacco plant composition. When a three-roll mill is used, the composition can be kneaded and dispersed by the compression force caused by being pressed between the narrow rolls and the shear force caused by the difference in roll speed, while being formed into a sheet of the desired thickness by the doctor blade, and a more homogeneous sheet can be produced than when a sheet is produced from a papermaking step [means] of a slurry. In addition to the three-roll mill, a press roller or a press machine can also be suitably used.

[0204] In the sheet forming step [means] S1, non-tobacco plants, aerosol formers, flavorings, antibacterial preservatives, binders or thickeners, water, etc. may be added as necessary.

[0205] The pure water used in the present invention is preferably sterilized or microorganism-free, but may be pure water obtained by reverse osmosis or ion exchange.

[0206] In this sheet forming step [means] S1, the mixture was formed into a sheet having a thickness of about 0.5 mm. The thickness of the sheet may be in the range of 0.1 to 1.0 mm, or 0.1 to 0.5 mm.

[0207] Next, this 0.5mm thick heated aroma-generating sheet was cut into a heated aroma-generating sheet and a heated aroma-generating filler in the same manner as in (Production Example 2), then processed into a heated aroma-generating body and assembled into an aroma cartridge. When <Evaluation 1> was similarly performed, a result of rank A was obtained, making it clear that the heated aroma-generating sheet manufactured by this method [apparatus] also functions as a gas generation sustaining material for the heated aroma-generating base.

[0208] As described above, it has become clear that heated aroma-generating substrates using non-tobacco materials have a wide variety of constituent compositions and properties, and that the non-uniformity of the mixed, dispersed, and dissolved states of these materials leads to changes over time, such as bleeding out of the aerosol former from the heated aroma-generating substrate, which reduces the amount of gas released from the heated aroma-generating substrate and reduces the amount of gas inhaled when smoking. Therefore, by improving this non-uniformity, the change over time in the amount of gas inhaled can be resolved.

[0209] Furthermore, we found that the cause of the problems specific to aroma cartridges using non-tobacco materials is the binder or thickener, which is one of the constituent materials of the heated aroma-generating substrate using non-tobacco materials. These are added to prevent the destruction of the mass state that occurs because it is not possible to contain a large amount of fiber, and the fusion that occurs inside the heated aroma-generating substrate and between the heated aroma-generating substrates. However, it was found that if the amount added is increased, the density of the heated aroma-generating substrate increases and the mass state can be maintained, but the heated aroma-generating substrate shrinks over time and the bleeding out of the aerosol former becomes severe. Therefore, we investigated the amount, method [apparatus], and type of binder added, and found that the heated aroma-generating substrate manufactured by the method [apparatus] shown in Figure 31 can solve the above problems.

[0210] That is, the method includes steps [means] Z1 and Z2 of preparing a dried and ground non-tobacco material, a step [means] M1 of preparing a first binder aqueous solution by dissolving a first binder in pure water, a first wet mixing step [means] M1 of mixing the materials prepared in steps [means] Z4 and Z5 of preparing materials selected from an aerosol former, cross-linked PVP, flavoring, a non-tobacco material extract, β-cyclodextrin, microcrystalline cellulose, and an antimicrobial preservative, and a curing step [means] of stabilizing the mixture produced in the first wet mixing step [means]. ]Y1, a second wet mixing step [means] M2 of mixing the curing mixture produced in the curing step [means] with the second binder aqueous solution prepared in step [means] Z6 of dissolving the second binder in pure water, a sheet forming step [means] S1 of compressing the material produced in the second wet mixing step [means] to produce a heated aroma-generating sheet, and a sheet processing step [means] H1 of cutting or folding the heated aroma-generating sheet, the heated aroma-generating substrate produced can stably maintain a block state and does not block the gas flow path. Furthermore, no fusion between the heated aroma-generating substrates over time was observed.

[0211] A specific example of this manufacturing method (apparatus) is shown in Manufacturing Example 5.

[0212] (Production Example 5) In the step [means] Z1 of drying and pulverizing the non-tobacco plant material, it is preferable to adjust the moisture content so that the aerosol former, pure water, and other components can be easily absorbed or supported, and the drying temperature is preferably 60 to 80°C or less. In this range, it is easy to reach the desired moisture content while avoiding the dissipation of the required flavor components. In addition, if the temperature is 65°C or higher, it is even easier to reach the desired moisture content, and if it is 75°C or lower, it is even easier to prevent the dissipation of the required aroma components. In addition, the moisture content after drying and pulverization is preferably 5% by mass or less, which makes it easy to make a slurry in the subsequent step [means]. It is more preferable that it is 3% by mass or less. However, if the moisture content is less than 0.1% by mass, the affinity with water, etc. decreases. In addition, by providing a sieving step [means] for sieving the dried and pulverized product, a non-tobacco plant of the desired particle size can be introduced into the first wet mixing step [means] M3, making it easy to make a slurry.

[0213] Examples of the first binder used in the step [means] Z3 of preparing the first binder by dissolving it in pure water include celluloses, konjac mannan (glucomannan), guar gum, pectin, carrageenan, tamarin seed gum, gum arabic, soybean polysaccharides, locust bean gum, karaya gum, xanthan gum, agar, corn starch, etc., but celluloses are preferred. Regarding viscosity, if the solution viscosity is 300 mPa·s or more, it is suitable for mixing with non-tobacco plants. Also, if the solution viscosity is 5000 mPa·s or more, it is suitable for binding non-tobacco plants. The solution viscosity is measured using a Brookfield viscometer to prepare a 1% aqueous solution, and at 25°C, at 10 to 30 rpm, the rotor starts to rotate, and the displayed value stabilizes. Here, the upper limit of measurement for the Brookfield viscometer is 100,000 mPa·s, but viscosities exceeding this upper limit also fall within the above-mentioned viscosity range.

[0214] The celluloses preferred as the first binder generally include cellulose, cellulose derivatives, and metal salts thereof, but in the present invention, water-soluble celluloses are particularly preferred from the viewpoint of binding non-tobacco plants. Examples of such celluloses include methyl cellulose, ethyl cellulose, carboxymethyl cellulose, carboxyethyl cellulose, hydroxymethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, and metal salts thereof such as sodium, potassium, and calcium. Among these, metal salts of celluloses are more preferred, and sodium carboxymethyl cellulose is even more preferred.

[0215] Examples of the aerosol former used in the step (means) Z4 of preparing an aerosol former include glycerin, propylene glycol, sorbitol, triethylene glycol, lactic acid, diacetin (glycerin diacetate), triacetin (glycerin triacetate), triethylene glycol diacetate, triethyl citrate, isopropyl myristate, methyl stearate, dimethyl dodecanedione, and dimethyl tetradecanedione, and are particularly preferred, with glycerin and propylene glycol being preferred. These are used in the range of 1 to 80% by mass, and more preferably 10 to 40% by mass, relative to the composition of the heated aroma-generating base material.

[0216] In step [means] Z5 of preparing items to be used other than those mentioned above, flavorings such as menthol, peppermint, cocoa, coffee, and black tea extracts can be added as necessary to add flavor, cross-linked PVP and β-cyclodextrin having the function of retaining flavorings, microcrystalline cellulose having releasability and moldability from molds, and food antibacterial preservatives such as sorbic acid, potassium sorbate, benzoic acid, and sodium benzoate for storage stability.

[0217] The materials prepared as above are mixed in the first wet mixing step [means] M1. The mixer does not need to be a special one, and may be, for example, a mixer that mixes the materials in the mixing tank while applying shearing force with a stirring blade, or it is possible to further strengthen the mixing by kneading using a roll mill, kneader, or extruder. The mixing temperature in this step [means] is preferably 40°C or less, more preferably 30°C or less, and even more preferably maintained at about 25°C. This is because if excessive heat is applied during mixing, the aroma components may dissipate. Therefore, it is necessary to control the temperature of the mixing tank.

[0218] The first mixture produced in the first wet mixing step [means] M1 is preferably subjected to a curing step [means] Y1 in which the mixture is left at a predetermined temperature for a predetermined time, but this is not a required step [means]. However, the binder must be added in portions to the first mixing step [means] and the second mixing step [means]. In this way, both the non-tobacco material mixture that has not been subjected to the curing step [means] Y1 in which the binder is added in portions and the cured mixture that has been subjected to the curing step [means] Y1 are processed into aroma cartridges with the heated aroma generating substrate, and when smoking is evaluated using, for example, the heated smoking device shown in FIG. 2, both the initial inhalation amount and the flavor are improved. Even when storage stability is evaluated in a high-temperature and high-humidity environment, there is no fusion inside the heated aroma generating substrate and between the heated aroma generating substrates, and there is no change over time in the amount of aerosol smoke and the amount of aroma components of the non-tobacco material released at the time of initial smoking, i.e., the amount of inhalation, and no change in flavor is observed. In particular, the effect is remarkable and preferable when tea is used as the non-tobacco material. However, the curing step [means] Y1 can further enhance these effects.

[0219] The temperature of the curing step [means] Y1 is preferably 15 to 30°C, more preferably 18 to 24°C. If it is 15°C or higher, the above-mentioned flavor improvement effect increases, and if it is 30°C or lower, the above-mentioned change in the amount of inhalation and the change in flavor over time are suppressed, and the improvement in the flavor over time is maintained. If it is 18 to 24°C, these effects are more significant. Furthermore, the time of the curing step [means] Y1 is preferably 72 to 336 hours, more preferably 96 to 192 hours. If it is 72 hours or more, the flavor is improved, and if it is 336 hours or less, the above-mentioned change in the amount of inhalation and the change in flavor over time are suppressed, and the improvement in the flavor over time is maintained. If it is 96 to 192 hours, these effects are more significant. And, it is preferable to perform the curing under sealing of the mixture after the first wet mixing. This is to prevent the flavor from dissipating.

[0220] The mixture immediately after the first wet mixing and the mixture that has been cured after the first wet step [means] are fed into the second wet mixing step [means] M2. The second wet mixing step [means] M2 is characterized by adding a second binder and mixing. In this way, the effect of adding the first binder and the second binder separately is not only the improvement of the initial absorption amount and flavor, and the reduction of the change over time in the absorption amount and flavor, but also the facilitating molding into the desired shape in the sheet molding step [means] H1. Also, mixing is easier than adding in the first step [means], and the time until the viscosity of the mixture becomes uniform can be shortened, making it easier to adjust the viscosity.

[0221] As with the first binder, celluloses, konjac mannan (glucomannan), guar gum, pectin, carrageenan, tamarin seed gum, gum arabic, soybean polysaccharides, locust bean gum, karaya gum, xanthan gum, agar, starch, corn starch, etc. can be used as the second binder, but polysaccharides other than celluloses are preferred. As with the first binder, a solution viscosity of 300 mPa·s or more allows for good mixing with non-tobacco plants. A solution viscosity of 5000 mPa·s or more is also suitable for binding non-tobacco plants. This viscosity was also measured using the method [apparatus] described above. The upper limit of measurement for the Brookfield viscometer is 100,000 mPa·s, but viscosities exceeding this upper limit also fall within the above-mentioned viscosity range.

[0222] As the second binder, polysaccharides are preferably used. It is particularly preferable to use polysaccharides that are water-soluble or swell with water or gel. By using such a polysaccharide, the molded heated aroma-generating substrate maintains a block state, improves moldability, and reduces the occurrence of sheet destruction and non-tobacco material falling off in the sheet molding step [means] H1. Examples of such polysaccharides include glucomannan, guar gum, pectin, carrageenan, locust bean gum, and agar. When adding, it is preferable to use these with a solution viscosity higher than that of the first binder. By using a binder in this way, the processing suitability in the sheet molding step [means] 11 is further improved. Among them, glucomannan is the most preferable.

[0223] In this second wet mixing step [means] M2 as well, it may be preferable to use a manufacturing method [apparatus] in which, as necessary, flavorings such as menthol, peppermint, cocoa, coffee, and black tea extracts, cross-linked PVP and β-cyclodextrin having the function of retaining flavorings, microcrystalline cellulose having releasability and moldability from molds, and food antibacterial preservatives such as sorbic acid, potassium sorbate, benzoic acid, and sodium benzoate for storage stability are prepared and added in the same manner as in step [means] Z5.

[0224] When the materials prepared as described above are mixed in the second wet mixing step [means] M2, a normal wet mixer can be used, as in the first wet mixing step [means] M1. For example, a mixer that mixes the materials in the mixing tank while applying shearing force with a stirring blade may be used, and it is also possible to further strengthen the mixing by kneading using a roll mill, kneader, or extruder. The mixing temperature in this step [means] is preferably 40°C or less, more preferably 30°C or less, and even more preferably maintained at about 25°C. This is because if excessive heat is applied during mixing, the aroma components may dissipate. Therefore, it is necessary to control the temperature of the mixing tank.

[0225] Next, the composition of the heated aroma-generating substrate containing the non-tobacco material produced in the second wet blend M2 is fed into a sheet forming step [means] H1 and processed into a desired shape. To use this composition as a heated aroma-generating substrate, a sheet forming process such as roll forming or press forming is preferred, but is not limited to these. A method [apparatus] of passing the composition through an orifice under pressure to form it into a rod shape, or a method [apparatus] of drying and then pulverizing it into granules may also be used.

[0226] Here, a sheet forming process suitable for manufacturing a heated aroma generating substrate is described. As one method [apparatus], a three-roll mill was used to form a sheet. When a three-roll mill is used, it is possible to form a sheet of a desired thickness by a doctor blade while kneading and dispersing by the compression force caused by being pushed between narrow rolls and the shear force caused by the speed difference between the rolls, and this is particularly preferable for sheet forming such as the composition of the present invention in which a wide variety of materials with different properties are mixed. It may also be produced by using a press roller or a press machine in combination. In this way, the three-roll mill processes into a sheet shape while kneading and dispersing, so it complements the first and second wet mixing, and can achieve a more preferable mixed and dispersed state. Therefore, when a three-roll mill is used in the second wet mixing step [means] M2, there is no difference in the apparatus between the second wet mixing step [means] M2 and the sheet forming step [means] H1, which means that mixing and forming are performed in the same process.

[0227] In this way, since mixing and dispersion can be carried out in sheet formation using a triple roll mill, it is also possible to use a manufacturing method [apparatus] in which non-tobacco materials, aerosol formers, binders or thickeners, flavorings, cross-linked PVP, β-cyclodextrin, microcrystalline cellulose, antibacterial preservatives, pure water, etc. can also be added as necessary.

[0228] In order to clarify the characteristics of the method [apparatus] for producing a heated aroma-generating base material, which is characterized by adding the first and second binders in separate portions, the materials used were made common and the form of the heated aroma-generating base material was limited to a filler, and the method was compared with a conventional manufacturing method [apparatus]. The present invention will be described with reference to manufacturing examples and working examples.

[0229] (Manufacturing example A) Xylitol 100 parts by weight 400 parts by mass of water The mixture was stirred to obtain a xylitol / water solution.

[0230] Next, black tea leaves were dried at 70°C, crushed, and passed through an 80-mesh sieve. The moisture content was 2% by mass. Similarly, dried sweet potato vine was crushed and passed through an 80-mesh sieve.

[0231] Dried and ground black tea leaves 80 parts by weight 20 parts by weight of dried and crushed sweet potato vine Methylcellulose 15 parts by weight Glycerin 30 parts by weight Propylene glycol 30 parts by weight Sodium carboxymethylcellulose 4 parts by weight Xylitol / water solution 8 parts by weight were charged into a mixer and mixed for 15 minutes (first wet mixing step [means] M1) to obtain a first mixture.

[0232] The obtained first mixture was put into the second wet mixing step [means] M2. 100 parts by mass of the first mixture was put into a three-roll mill, while 0.5 parts by mass of glucomannan and 20 parts by mass of water were added. Then, the step [means] of pressing a doctor blade against the roll to collect a sheet-like material was repeated eight times. In this step [means], the second wet mixing step [means] M2 and the sheet forming step [means] H1 are performed in the same device, and the first half of the mixing can be regarded as the second mixing step [means] M2 and the second half of the mixing can be regarded as the sheet forming step [means] H1. Then, a sheet of the desired thickness was produced in the three-roll mill while also serving as kneading and dispersion.

[0233] The heated aroma-generating sheet manufactured through these steps [means] was formed to a thickness of 0.3 mm. This sheet was cut into a rectangle of 150 mm length x 240 mm width, fed to a rotary cutter, and processed into a shape of 1.5 mm width, 240 mm length, and 0.3 mm thickness to form a heated aroma-generating filling. 50 of these fillings were bundled and aligned in the longitudinal direction, and then cut into a shape of 34 g / m2 basis weight. 2 The heated aroma-generating sheet was wrapped in paper and glued to form a cylindrical heated aroma-generating processed product. The inner diameter of this processed product was 6.9 mm. This was then cut to a length of 12.0 mm to form a heated aroma-generating body. The mass of this heated aroma-generating body was 0.29 g, and the volumetric filling rate of the filler relative to its volume was 0.60. The length of the rectangle into which the heated aroma-generating sheet was cut was parallel to the rotation axis of the roll, and the width was the rotation direction of the roll (the same applies below).

[0234] The aqueous solution viscosity of the sodium carboxymethylcellulose used in this manufacturing example was 650 mPa·s (Brookfield viscometer, 1% aqueous solution, 25°C), and the aqueous solution viscosity of the polysaccharide glucomannan was 44,000 mPa·s (Brookfield viscometer, 1% aqueous solution, 25°C).

[0235] (Manufacturing example B) Up to the first wet mixing step [means] M1, the first mixture was prepared in the same manner as in (Production Example A). The first mixture was put into a polyethylene bag and sealed, and cured at a temperature of 20°C for 6 days (144 hours) to prepare a cured mixture. After the curing step [means] Y1, the apparent volume was about 1.5 times larger. When the second cured mixture after the curing step [means] Y1 was checked, it was found that less tea powder was liberated compared to before curing, and it is considered that curing leads to a stable and uniformly dispersed state. The mixture prepared by the curing step [means] Y1 was put into the second wet mixing step [means] M2, and a heated aroma generating body was prepared in the same manner as in (Production Example A).

[0236] (Manufacturing example C) As in (Production Example B), the curing mixture was put into the second wet mixing step [means] M2 and passed through the sheet forming step [means] H1 to produce a heated aroma-generating sheet, but in this production example, the processing conditions were changed in the second wet mixing step [means] and the sheet forming step [means] H1, and the heated aroma-generating sheet was produced by forming to a thickness of 0.1 mm. This sheet was cut into a rectangle of 150 mm length x 240 mm width and fed to a rotary cutter to produce a heated aroma-generating filling material of 1.0 mm width, 240 mm length and 0.1 mm thickness. 225 of these filling materials were bundled and aligned in the longitudinal direction, and then cut into a sheet of 34 g / m2 basis weight. 2 The product was wrapped in paper and glued to obtain a cylindrical heated aroma-generating processed product. The inner diameter of this processed product was 6.9 mm. This was then cut to a length of 12.0 mm to obtain a heated aroma-generating body. The mass of this heated aroma-generating body was 0.29 g, and the volumetric filling ratio of the filling material to its volume was 0.60.

[0237] (Manufacturing example D) As in (Production Example B), the curing mixture was put into the second wet mixing step [means] M2 and passed through the sheet forming step [means] H1 to produce a heated aroma-generating sheet, but in this production example, the processing conditions were changed in the second wet mixing step [means] and the sheet forming step [means] H1, and the heated aroma-generating sheet was produced by forming to a thickness of 0.5 mm. The heated aroma-generating sheet was cut into a rectangle of 150 mm length x 240 mm width and fed to a rotary cutter to produce a heated aroma-generating filling material of 1.0 mm width, 240 mm length and 0.5 mm thickness. 225 of these filling materials were bundled and aligned in the longitudinal direction, and then cut into a sheet of 34 g / m2 basis weight. 2 The product was wrapped in paper and glued to obtain a cylindrical heated aroma-generating processed product. The inner diameter of this processed product was 6.9 mm. This was then cut to a length of 12.0 mm to obtain a heated aroma-generating body. The mass of this heated aroma-generating body was 0.29 g, and the volumetric filling ratio of the filling material to its volume was 0.60.

[0238] For comparison, a heated aroma generating body was prepared by adding methyl cellulose and carboxymethyl cellulose as the first binder and glucomannan as the second binder all at once.

[0239] (Comparative manufacturing example) Xylitol 100 parts by weight 400 parts by mass of water The mixture was stirred to obtain a xylitol / water solution.

[0240] Next, black tea leaves were dried at 70°C, crushed, and passed through an 80-mesh sieve. The moisture content was 2% by mass. Similarly, dried sweet potato vine was crushed and passed through an 80-mesh sieve.

[0241] Dried and ground black tea leaves 80 parts by weight 20 parts by weight of dried and crushed sweet potato vine Methylcellulose 15 parts by weight Glycerin 30 parts by weight Propylene glycol 30 parts by weight Sodium carboxymethylcellulose 4 parts by weight Xylitol / water solution 8 parts by weight Glucomannan 0.5 parts by weight 20 parts by mass of water The ingredients were added to a mixer and mixed for 15 minutes to obtain a mixture containing all the ingredients including glucomannan.

[0242] The mixture thus prepared was mixed in a three-roll mill, and the doctor blade was pressed against the roll to obtain a sheet-like material. This process [means] was repeated eight times to prepare a heated aroma-emitting sheet 0.3 mm thick while also kneading and dispersing the mixture. However, there were difficulties in forming the sheet when using the three-roll mill. Furthermore, although the sheet was formed, it was not possible to measure the evaluation of A.

[0243] The heated aroma-generating sheet thus produced was cut into a rectangle measuring 150 mm long x 240 mm wide, fed to a rotary cutter, and processed into a heated aroma-generating filling material with a width of 1.5 mm, length of 240 mm, and thickness of 0.3 mm. 50 pieces of this filling material were bundled and aligned in the longitudinal direction, and then cut into a sheet with a basis weight of 34 g / m2. 2 The heated aroma-generating product was wrapped in paper and glued to obtain a cylindrical heated aroma-generating product. The inner diameter of this product was 6.9 mm. This was then cut to a length of 12.0 mm to obtain a heated aroma-generating body. The mass of this heated aroma-generating body was 0.29 g, and the volumetric filling ratio of the filling material to its volume was 0.60.

[0244] Example A Using the heated aroma generating unit produced in (Production Example A), an aroma cartridge was produced in which the heated aroma generating unit was joined to a mouthpiece equipped with a support member and a filter, as shown in Figure 13. The support member was a PE tube with an outer diameter of 6.9 mm and a through hole with an inner diameter of 4.0 mm. The filter was made of acetyl cellulose fiber molded into a cylindrical shape with a basis weight of 34 g / m2. 2 The cartridge exterior was wrapped in paper with a length of 23 mm and had a basis weight of 38 g / m 2 The cartridge exterior was made of paper with a grammage of 32 to 45 g / m2, wrapped around two and a half times so that the inner diameter was 6.9 mm, and glued. 2 When a paper cylinder formed by wrapping the paper around it two and a half times is used, it becomes suitable as an aroma cartridge in which the heated aroma generating unit is inserted into the heating element of a heated smoking device. Then, a support member and a filter are inserted into one end of the cartridge exterior body to form a mouthpiece, and the heated aroma generating unit is inserted into the other end, and then a paper cylinder with a basis weight of 40 g / m is inserted so as to overlap the mouthpiece. 2 However, in order to clarify the effect of the manufacturing method [apparatus] on the heated aroma-generating substrate, i.e., the difference in the function of the gas generation sustaining material, a filter without a cavity, which is a suction optimization means, was used.

[0245] Example B An aroma cartridge was produced in the same manner as in (Example A), except that the heated aroma generating body produced in (Production Example B) was used.

[0246] Example C An aroma cartridge was produced in the same manner as in (Example A), except that the heated aroma generating body produced in (Production Example C) was used.

[0247] Example D An aroma cartridge was produced in the same manner as in (Example A), except that the heated aroma generating body produced in (Production Example D) was used.

[0248] Comparative Example Except for using the heated aroma-generating body prepared in Comparative Manufacturing Example, an aroma cartridge was prepared in the same manner as in Example A. However, during preparation of the aroma cartridge, the heated aroma-generating filling material was too soft, and preparation was difficult.

[0249] The heated aroma generating sheets and aroma cartridges prepared as described above were evaluated as follows. In addition to the evaluations below, evaluation 1 was also performed.

[0250] <Rating: A> A tensile strength test was conducted on the heated aroma-generating sheet. A commonly used tensile strength testing machine was used for the tensile strength test. The sample used was a heated aroma-generating sheet cut to a width of 10.0 cm and a length of 22.0 cm, and measurements were taken with a clamp distance of 20.0 cm and a crosshead speed of 10 cm / min for the tensile strength test. The test environment was a room temperature of 20°C and a humidity of 50%. The heated aroma-generating sheets produced by each manufacturing method [device] were evaluated by comparing their breaking strengths, and the breaking strength was found to be 3.9 N / mm 2 More than 5.0N / mm 2 It was found that having the above strength is generally favorable in terms of molding and processing, preparation of the aroma cartridge, initial inhalation amount, initial flavor, and changes over time in the inhalation amount and flavor.

[0251] <Evaluation: B> The heated smoking tool used was IQOS (registered trademark), a heated electronic cigarette device manufactured by Philip Morris, which has the system shown in FIG. 2(A). The heating element has a width of 4.5 mm, a length to the tip of 12 mm, and a thickness of 0.4 mm. The inner diameter of the chamber is 7 mm, so that the aromatic cartridge is inserted therein without any gaps, and the outer diameter of the aromatic cartridge is 6.9 mm. The heating element is heated by power supplied from a battery installed in the heated electronic cigarette body, and the temperature reaches approximately 350°C. The built-in control system controls the consumption of one cigarette with a conventional electronic cigarette cartridge by 14 puffs. When the smoking cigarette cartridge of this example is inserted, the aromatic cartridge part that appears from the downstream side of the electronic cigarette device body to the outside is about 20 mm. The aromatic cartridges manufactured in this example and the comparative example were inserted into the chamber of the electronic cigarette device, and a smoking test was performed. Both the amount of inhalation and the flavor were sensory evaluations in the oral cavity during smoking, and in particular, the flavor was evaluated for the aroma of tea immediately after the aromatic cartridge was made and after it was left as it was in <Evaluation 1>. The sensory test was conducted by five subjects. The evaluation criteria were as follows: Rank A: When smoking, there is a sufficient amount of inhalation, there is no resistance to inhalation, and the aroma of tea can be enjoyed. Rank B: When smoking, the amount of inhalation is insufficient, there is resistance to inhalation, and the tea aroma is unsatisfactory.

[0252] <Evaluation: C> The falling off of the filling after smoking was evaluated. The evaluation method [apparatus] was to orient the heated aroma generating body side of the aroma cartridge vertically downward after smoking and observe whether the heated aroma generating filling fell off or not. The evaluation criteria were as follows. Rank A: No falling objects seen Rank B: Some of the filling has fallen off

[0253] The test results are shown in Table 1. As is clear from Table 1, the effect of adding the binder in portions was recognized in all of the molding process, aroma cartridge production, initial inhalation volume and flavor, changes in inhalation volume and flavor over time, and fusion of the heated aroma-generating filling material over time, and curing can further enhance this effect. Therefore, it is clear that the heated aroma-generating base material to which the binder has been added in portions, and the heated aroma-generating base material produced by further subjecting it to a curing process [means] function as a gas generation sustaining material for the aroma cartridge.

[0254] [Table 1]

[0255] As described above, it has been confirmed that the manufacturing method [apparatus] affects the internal structure of the heated aroma-generating substrate, and functions as a gas generation-sustaining material in the aroma cartridge made using the heated aroma-generating substrate made by the appropriate manufacturing method [apparatus]. In the present invention, we have also found something that functions as a gas generation-sustaining material. It is inorganic particles.

[0256] The effect of inorganic particles will be explained with specific examples. To this end, (Production Example 1) was adopted as a conventional production method [apparatus], and the effect of various inorganic particles on the gas generation sustainability of the heated aroma-generating substrate produced by this production method [apparatus] was evaluated as follows.

[0257] According to (Manufacturing Example 1), the heated aroma generating body is produced and the aroma cartridge is assembled. In this embodiment, as shown in the scattering step [means] H2 in FIG. 32, the heated aroma generating sheet produced in (Manufacturing Example 1) is cut to a length of 12 mm x width of 1.5 mm (thickness of 0.5 mm), and after the heated aroma generating filling is produced, a step [means] is added in which a predetermined amount of various inorganic particles are added and scattered and sprinkled so as to be uniformly attached to the surface of the heated aroma generating filling. Such a step [means] is intended to uniformly attach the inorganic particles to the surface of the heated aroma generating filling. In addition, in this step [means], the surface of the heated aroma generating filling was observed under a microscope to confirm that the inorganic particles were attached to the surface of the heated aroma generating filling. Next, the heated aroma generating filling to which the inorganic particles were attached was processed into a heated aroma generating body and assembled into an aroma cartridge according to (Manufacturing Example 1). Furthermore, in order to clarify the effect of the inorganic particles, the filling rate was increased. The aroma cartridge produced in this manner was subjected to <Evaluation 1>. Furthermore, the following "Evaluation 2" was carried out using the heated electronic cigarette device described in "Evaluation B".

[0258] <Evaluation 2> The following evaluation was performed after checking the dirt adhering to the heating element 113 when the aroma cartridge was used as shown in FIG. 2(C). First, 14 puffs were performed for each aroma cartridge of Comparative Example 1, and the dirt adhering to the heating element when 10, 20, 30, 40, and 50 puffs were completed was wiped off with gauze impregnated with ethanol, and the degree of dirt was recorded. Then, the dirt was collected in the same manner as in Comparative Example 1 when 50 aroma cartridges of the present embodiment, which were made using a heated aroma-generating filling material having various inorganic particles attached to the surface, were puffed up, and the degree of dirt was compared and evaluated with the degree of dirt recorded in Comparative Example 1. The index of evaluation was the number of cartridges that matched the degree of dirt when 50 aroma cartridges of the present embodiment were puffed up with the aroma cartridge of Comparative Example 1. Therefore, the smaller the number, the better.

[0259] Example I For 100 parts by mass of the heated aroma-generating filling cut from the heated aroma-generating sheet produced in (Production Example 1) as described above, 1 part by mass of calcium carbonate powder with an average particle size of 15 μm was scattered and dusted so as to adhere to the entire surface of the heated aroma-generating filling. After confirming by microscopic observation that calcium carbonate particles with a diameter of 10 to 50 μm were attached to the heated aroma-generating filling, a heated aroma-generating body was produced using 0.29 g of the heated aroma-generating filling having calcium carbonate particles on its surface. Then, an aroma cartridge was assembled from this heated aroma-generating body and a mouthpiece. The filling rate of the filling in this case was measured and found to be 81%.

[0260] Example II For 100 parts by mass of the heated aroma-generating filling cut from the heated aroma-generating sheet produced in (Production Example 1) as described above, 1 part by mass of magnesium carbonate powder with an average particle size of 10 μm was scattered and dusted so as to adhere to the entire surface of the heated aroma-generating filling. After confirming by microscopic observation that magnesium carbonate particles with a diameter of 10 μm to 50 μm were attached to the heated aroma-generating filling, a heated aroma-generating body was produced using 0.29 g of the heated aroma-generating filling having magnesium carbonate particles on its surface. Then, an aroma cartridge was assembled from this heated aroma-generating body and a mouthpiece. The filling rate of the filling in this case was measured and found to be 80%.

[0261] Example III For 100 parts by mass of the heated aroma-generating filling cut from the heated aroma-generating sheet produced in (Production Example 1) as described above, 1 part by mass of silicon oxide particles having an average particle size of 20 μm was scattered and dusted so as to adhere to the entire surface of the heated aroma-generating filling. After confirming by microscopic observation that silicon oxide particles having a diameter of 10 μm to 50 μm were adhered to the heated aroma-generating filling, a heated aroma-generating body was produced using 0.29 g of the heated aroma-generating filling having silicon oxide particles on its surface. Then, an aroma cartridge was assembled from this heated aroma-generating body and a mouthpiece. The filling rate of the filling in this case was measured and found to be 80%.

[0262] Example IV For 100 parts by mass of the heated aroma-generating filling cut from the heated aroma-generating sheet produced in (Production Example 1) as described above, 1 part by mass of alumina particles having an average particle size of 5 μm was scattered and dusted so as to adhere to the entire surface of the heated aroma-generating filling. After confirming by microscopic observation that alumina particles having a diameter of 10 μm to 50 μm were attached to the heated aroma-generating filling, a heated aroma-generating body was produced using 0.29 g of the heated aroma-generating filling having alumina particles on its surface. Then, an aroma cartridge was assembled from this heated aroma-generating body and a mouthpiece. The filling rate of the filling in this case was measured and found to be 81%.

[0263] Example V For 100 parts by mass of the heated aroma-generating filling cut from the heated aroma-generating sheet produced in (Production Example 1) as described above, 1 part by mass of alumina particles having an average particle size of 2 μm was scattered and dusted so as to adhere to the entire surface of the heated aroma-generating filling. In this case, it was not possible to confirm by microscopic observation that alumina particles having a diameter of 10 μm to 50 μm were attached to the heated aroma-generating filling, but a heated aroma-generating body was produced using 0.29 g of the heated aroma-generating filling dusted with alumina particles. Then, an aroma cartridge was assembled from this heated aroma-generating body and a mouthpiece. The filling rate of the filling in this case was measured and found to be 81%.

[0264] Example VI For 100 parts by mass of the heated aroma-generating filling cut from the heated aroma-generating sheet produced in (Production Example 1) as described above, 1 part by mass of silicon oxide particles having an average particle size of 0.5 μm was scattered and dusted so as to adhere to the entire surface of the heated aroma-generating filling. Microscopic observation again failed to confirm that silicon oxide particles having a diameter of 10 μm to 50 μm were attached to the heated aroma-generating filling, but a heated aroma-generating body was produced using 0.29 g of the heated aroma-generating filling dusted with silicon oxide particles. An aroma cartridge was then assembled from this heated aroma-generating body and a mouthpiece. The filling rate of the filling in this case was measured and found to be 81%.

[0265] Example VII For 100 parts by mass of the heated aroma-generating filling cut from the heated aroma-generating sheet produced in (Production Example 1) as described above, 1 part by mass of silicon oxide particles having an average particle size of 47 μm was scattered and dusted so as to adhere to the entire surface of the heated aroma-generating filling. After confirming by microscopic observation that silicon oxide particles having a diameter of 10 μm to 50 μm were attached to the heated aroma-generating filling, a heated aroma-generating body was produced using 0.29 g of the heated aroma-generating filling dusted with silicon oxide particles. Then, an aroma cartridge was assembled from this heated aroma-generating body and a mouthpiece. The filling rate of the filling in this case was measured and found to be 65%.

[0266] (Comparative example I) 0.29g of the heated aroma-generating filling material cut from the heated aroma-generating sheet produced in (Production Example 1) as described above was used to produce a heated aroma-generating body. An aroma cartridge was then assembled from this heated aroma-generating body and a mouthpiece. The filling rate of the filling material in this case was measured and found to be 81%.

[0267] The above evaluation results are shown in Table 2. As is clear from the table, inorganic particles with a wide range of particle sizes function as gas generation sustaining materials regardless of their material. As is clear from the results of <Evaluation 1>, the heated aroma generating filler does not fuse over time, and there is little change over time in the amount of gas released, i.e., the amount of gas sucked in and the flavor. The reason for this effect is unclear, but it is thought to be as follows. When inorganic particles are present on the surface of the filler, the inorganic particles act as spacers to reduce the contact area between the fillers, and even when placed in a high temperature state for a long time, they have the effect of inhibiting the fusion of the fillers due to the bleeding out of the aerosol former, and the inorganic particles have the effect of suppressing the bleeding out of the aerosol former.

[0268] [Table 2]

[0269] Furthermore, as is clear from <Evaluation 2>, it was recognized that the inorganic particles also have the effect of preventing contamination of the heating element. In particular, when the average particle diameter of the inorganic powder to be added is 1 to 50 μm, it has a good effect, and when it is 5 μm or more, the effect of preventing contamination is further enhanced. When the amount of the inorganic powder to be added is 0.01 to 5 parts by mass, it has a good effect, and when it is 0.1 parts by mass or more, the effect of preventing contamination is further enhanced. The reason why the inorganic particles have the effect of preventing contamination of the heating element is not clear, but is presumed to be as follows. The inorganic material is difficult to decompose by heat, the inorganic particles polish the surface when the aroma cartridge is attached to and detached from the heating element, and the inorganic particles reduce the contact area between the heating element surface and the heated aroma-generating filling material.

[0270] In order to obtain such an effect, it is preferable that the inorganic particles have an average particle diameter of 1 to 100 μm. If the average particle diameter is less than 1 μm, the effect of the inorganic particles is reduced. On the other hand, if the average particle diameter is 5 μm or more, the effect of the inorganic particles is enhanced, which is more preferable. For the same reason, it is even more preferable that the diameter is 10 μm or more. In addition, the larger the particle diameter, the lower the filling rate of the filler, but if the particle diameter is 50 μm or less, the effect of the inorganic particles is large and the minimum necessary filling rate can be ensured.

[0271] Here, the minimum filling rate is closely related to the amount of gas that is generated by heating and drawn in. If the filling rate is less than 60%, the amount of gas released by heating is insufficient, and the amount of gas that the smoker draws in is insufficient, resulting in an unsatisfactory smoking experience. Therefore, a filling rate of 65% or more is more preferable, and 70% or more is even more preferable. On the other hand, if the filling rate exceeds 90%, there are few gaps between the filling materials, making smoking difficult and insertion into the heating element difficult.

[0272] The filling rate can be evaluated by calculating the area ratio of the heated aroma generating substrate in the cross section of the heated aroma generating body. The filling rate was determined by evaluating the filler and the voids without the filler using a digital microscope. A digital microscope (Keyence: VHX-2000) was used, and the image was projected on a display at a magnification of 100 times. The area to be analyzed in the image was the area where only the filler and the voids without the filler appeared. In this case, the observation sample diameter was 7.0 mm, and the width was 3.5 mm and the height was 2.6 mm. In the above range, the image was analyzed using the attached software, and the "extraction mode" was set to "brightness" in the "automatic measurement mode". For the measurement, "standard" was selected, the "extraction parameter" was set to "bright", and the "threshold" was selected so that the filler and the voids to be observed were separated. The filling rate was determined as the ratio of the filler to the entire measurement area.

[0273] The average particle size of the inorganic particles in the present invention is determined by a laser diffraction / scattering method. The average particle size was determined by a wet method using a particle size distribution measuring device. In the present invention, a Microtrac MT3300III manufactured by Microtrac Bell was used. The average particle size of the present invention is determined by accumulating the volume-based distribution in the range of 0.02 μm to 2000 μm, and finding the median diameter D at 50%. 50 Refers to...

[0274] Furthermore, the presence of inorganic particles in the present invention was confirmed not only by microscopic observation during the manufacturing process [means], but also by observation of the surface of the filler using an optical microscope or an electron microscope. Furthermore, it was also confirmed by microscopic or electron microscope observation of the residue of pyrolyzing the filler. This was based on the results of observation of about 10 sheets at an appropriate magnification with a field of view of 100 μm × 100 μm. Furthermore, it was confirmed that the inorganic particles of the residue were the added inorganic particles using a scanning electron microscope equipped with X-ray microanalysis (XMA).

[0275] The amount of inorganic particles added must be at least 0.001 parts by mass relative to 100 parts by mass of the filling material in order to exhibit its effect, and is more preferably 0.01 parts by mass or more, and even more preferably 0.05 parts by mass or more.On the other hand, if the amount exceeds 10 parts by mass relative to 100 parts by mass of the filling material, the filling rate of the filling material decreases, which affects the amount of gas suction and flavor.From this perspective, it is more preferably 5 parts by mass or less, and even more preferably 2 parts by mass or less.

[0276] The inorganic substance that can be used as the inorganic particles of the present invention is not particularly limited, but metal chlorides such as sodium chloride and potassium chloride, metal oxides such as magnesium oxide, calcium oxide, titanium oxide, iron oxide, and alumina, metal carbonates such as magnesium carbonate and calcium carbonate, metal sulfates such as magnesium sulfate and calcium sulfate, metal phosphates such as calcium phosphate, and titanates such as potassium titanate and magnesium titanate can be used alone or in combination of two or more. Furthermore, silicon oxides such as zeolite, colloidal silica, and fumed silica, and natural products such as diatomaceous earth and vermiculite can also be used. In particular, magnesium carbonate, calcium carbonate, silicon oxide, and alumina are preferred.

[0277] In this way, the inorganic particles can be attached to the heated aroma-generating substrate in the spraying step [means] H2 in FIG. 32, but can also be attached in the spraying step [means] S4 in FIG. 32. Furthermore, as shown in FIGS. 28-31, inorganic particles can be added to the heated aroma-generating composition to prepare a heated aroma-generating substrate containing inorganic particles. In the case of this method [apparatus], the inorganic particles are not present only on the surface of the heated aroma-generating substrate, but it has been confirmed that the effect of the inorganic particles is expressed. For this reason, it is speculated that the inorganic particles function as a gas generation sustaining material because the inorganic particles not only reduce the contact area as a spacer that inhibits fusion between the heated aroma-generating substrates, but also hinder the movement of the constituent materials such as the aerosol former, non-tobacco material, and binder inside the heated aroma-generating substrate. This speculation is based on the fact that when inorganic particles are used as a filler in a polymeric material, they play the role of a crosslinking point, improving chemical properties such as heat resistance and chemical resistance, and physical properties such as tensile strength and elastic modulus.

[0278] As described above, by improving the manufacturing method [apparatus] according to the present invention, it is possible to provide a heated aroma generating unit in which a heated aroma generating substrate functions as a gas generation-sustaining material, and a heated aroma generating unit in which inorganic particles function as a gas generation-sustaining material. Therefore, it is possible to provide an aroma cartridge that does not require the provision of a gas suction optimization means in the mouthpiece, as shown in Figure 33. Of course, it is also possible to provide an aroma cartridge that combines a heated aroma generating unit equipped with a gas generation-sustaining material and a mouthpiece equipped with a gas suction optimization means. [Industrial Applicability]

[0279] The present invention provides a fragrance cartridge that allows not only experienced flame smokers but also first-time smokers to enjoy smoking with the sensation of smoking a cigarette, since the fragrance is derived from tobacco and its congeneric plants of the Solanaceae family, and from plants that do not contain its components, and therefore provides a new smoking tool that allows smokers to enjoy smoking without adversely affecting the health of not only the smokers themselves but also non-smokers around them, has a healing effect that brings about alpha waves in the brain, and is useful for promoting health and beauty. Moreover, since the fragrance cartridge is equipped with a gas suction optimization means and a gas generation sustaining material, it has the characteristic that the amount of smoke and aroma components suctioned and the amount of smoke suctioned do not change even if it is stored for a long period of time. Therefore, the technology related to the fragrance cartridge of the present invention may be widely applied to incense sticks, burning incense, powdered incense, incense paste, aromatherapy, etc. [Explanation of symbols]
