Description

Technical Field

[0001] The present invention relates to an aromatic cartridge that is mounted in a chamber provided with an electrically controlled heating element of a heated smoking device so as to be in contact with the heating element and that can enjoy the aerosol smoke and aroma components generated by heating the heating element.

Background Art

[0002] In recent years, as the separation of tobacco and smoking bans have become widespread in spaces where people gather, such as workplaces and restaurants, the number of smokers who inhale the smoke of tobacco burned by a flame, such as rolled cigarettes, has decreased. On the other hand, the number of smokers who use electronic cigarettes, which are heated smoking devices that suck in the smoke generated by the heat transmitted by an electrically controlled heating element such as a heater, has increased rapidly. The reason for this is that, according to conventional flame smoking, smokers and non-smokers around them inhale harmful substances generated by the thermal decomposition and combustion (600°C or higher) of tobacco materials and paper, whereas according to electronic cigarettes, smokers can inhale harmless smoke and aromas such as glycerin made from tobacco materials and aerosol formers at a low temperature (200 to 350°C) that does not lead to the thermal decomposition and combustion of tobacco materials, and enjoy smoking, and the impact on non-smokers around them can also be reduced.

[0003] Such electronic cigarettes are roughly classified into two types (Non-Patent Documents 1 and 2). One is a capsule-type electronic cigarette and a stick-type electronic cigarette that heat a capsule or stick containing tobacco leaves or the like and suck in smoke or the like. The other is a liquid-type electronic cigarette that heats a liquid with a scent or taste and inhales the generated vapor.

[0004] In particular, stick-type electronic cigarettes are highly similar to conventional paper cigarettes in terms of form, smoking method, taste, etc., and have a small amount of harmful substances inhaled like paper cigarettes, so they have many enthusiasts and various developments have been carried out (for example, Patent Documents 1 to 3). Specifically, an aerosol former that generates an aerosol that becomes smoke, a fragrance, a binder, etc., together with tobacco components, is processed into a stick shape like a paper cigarette, and a stick (electronic cigarette cartridge) equipped with a mouthpiece is attached to a heat-type smoking device for smoking. The smoking mechanism is that when the aerosol former is heated by being attached so as to be in contact with the heat source of the heat-type smoking device, volatiles containing the aerosol former are released from the aerosol former. At the same time, this volatile is inhaled together with air to the mouthpiece side at the other end by the smoker's suction. In the conveyance process of this volatile, the volatile of the aerosol former cools and condenses to form an aerosol like smoke, and the other volatiles give an aroma to the smoker's mouth and nose, and as a result, smoking can be enjoyed (Patent Document 2). According to this mechanism, in the case of heat-type smoking such as stick-type electronic cigarettes, smoking can be carried out at a temperature of about 200 to 250 °C 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 starts. Therefore, compared with the case of flame-type smoking that burns at a temperature of at least 600 °C required for combustion and further exceeds 900 °C during smoking, the generation of harmful substances, which is said to increase with the rise in temperature, is suppressed, and there is little adverse effect on health.

[0005] In addition, unlike stick-type e-cigarettes, liquid-type e-cigarettes do not contain tobacco components and are new smoking devices that allow users to enjoy various flavors, such as beverages like coffee, cola, and Red Bull, desserts like chocolate, vanilla, and cream, fruits like orange, lemon, and melon, and cooling agents like menthol, mint, and herbs (Non-Patent Document 2). Specifically, they are e-cigarettes that heat a liquid in which flavors are mixed with propylene glycol and vegetable glycerin and inhale the volatiles evaporated therefrom. They are characterized by the fact that they contain no harmful substances, do not generate tar or nicotine, and allow users to enjoy a wide variety of flavors. In fact, a wide variety of liquids are on the market.

[0006] Furthermore, in recent years, attempts have been made to combine the characteristics of these two types of e-cigarettes (Patent Document 4). As described above, since the aerosol-forming body processed into a stick shape to be heated in a conventional stick-type e-cigarette contained tobacco components, although in small amounts, harmful substances were generated, as were tar and nicotine. Therefore, Patent Document 4 invented a stick-type e-cigarette that does not contain tobacco components, which was a problem with stick-type e-cigarettes. That is, instead of tobacco components, a non-tobacco material that generates only aromas that are effective in promoting physical and mental relaxation, health, and beauty through smoking is adopted, and a stick-type e-cigarette that uses an aerosol-forming body containing an aerosol former, a binder, etc. is used.

[0007] However, in such a stick-type e-cigarette that uses only non-tobacco materials, it is not possible to use a tobacco material containing a large amount of fibers in its aerosol-forming body, and there is a problem because a variety of non-tobacco materials are used to emit various flavors.

[0008] First, in the aerosol-forming body containing tobacco material, the fibers of the tobacco material maintained their lumpy state and prevented the tobacco material from falling off and fusing. However, when using a non-tobacco material that does not contain a large amount of fibers, in order to stably maintain the lumpy state of the heat-generating aromatic sheet or the heat-generating aromatic filling (hereinafter referred to as the "heat-generating aromatic base material"), a large amount of a binder or the like that performs the function of the fibers needs to be used. Therefore, when the binder increases, the density of the heat-generating aromatic base material becomes high, and the flow path (hereinafter referred to as the "gas flow path") of the aerosol former and the volatile components (hereinafter referred to as "gases") from inside the heat-generating aromatic base material of the non-tobacco material released by heating is blocked, making it difficult to suck the aerosol smoke and the aroma components (hereinafter referred to as "sucking components") of the non-tobacco material. As a result, the sucking amount decreases.

[0009] In addition, since the aerosol former is glycerin, propylene glycol, etc. which are liquids at normal temperature, the more the binder increases, the more it bleeds out from the heat-generating aromatic base material over time, and the heat-generating aromatic base materials fuse together. Therefore, the gas flow path is blocked, making it difficult to suck the sucking components, and as a result, the sucking amount decreases. Further, when such fusion occurs, not only does it become difficult to insert the heating element into the heat-generating aromatic base material, but the heating element may also be damaged. Specifically, during transportation or storage in a warehouse or storefront, the heat-generating aromatic base materials stick together and harden, 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 addition amount of the binder or the like is reduced to ensure the gas flow path, the non-tobacco material may fall off or dust may be generated, making it difficult to firmly maintain the form of the cartridge, and it may be broken when inserted into the heating element. In addition, these may also be sucked 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] Here, it is referred to as an "aromatic cartridge", but it may also be called a "smoking cartridge" or an "e-cigarette compatible cartridge".

[0016] What serves as the source of the fragrance also applies to those that use a non-tobacco material without tobacco components.

[0017] "Aroma" means "pleasant smell", and includes the smell (fragrance) wafting from the material itself, the smell (aroma) wafting in the air when heated, the smell (flavor) wafting in the mouth when inhaled, etc.

[0018] "Smoking" generally often means inhaling tobacco, but here it simply means "enjoying the smoke", "tasting the smoke", "appreciating the smoke", and the source of the smoke is not limited to tobacco and also applies to those that use non-tobacco materials. Also, the "smoke" here includes things that "look like smoke" and "smoky things" such as droplets dispersed in the air like aerosol.

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

[0020] More specifically, in a cylindrical aromatic cartridge that is mounted in contact with the heating element of a heated smoking device equipped with an electrically controlled heating element in a chamber and can enjoy the aerosol smoke and aroma components generated by heating the heating element, a mouthpiece having a filter for filtering at least the smoke and aroma components and a heated aroma generating body in which a heated aroma generating base material that contacts at least the heating element is wound are adjacent and wound by a cartridge outer body, and the mouthpiece has a mechanism for improving the gas suction amount and a function for capturing drop-off materials and dust such as non-tobacco materials, and the purpose is to provide an aromatic cartridge provided with a material having a structure without drop-off or dust of non-tobacco materials and so on and not reducing the gas suction amount of the heated aroma generating body.

Means for Solving the Problem

[0021] That is, the aromatic cartridge of the present invention includes a heated aromatic generating body around which a heated aromatic generating base material in contact with a heating element is wound, a mouthpiece including a filter for filtering aerosol smoke and fragrance components generated by heating from the heating element, and a cartridge exterior body that wraps around the outer periphery so as to connect the heated aromatic generating body and the mouthpiece. At least one of the heated aromatic generating body and the mouthpiece has at least one of means for optimizing the suction of the smoke and the fragrance components and a gas generation sustaining material for the smoke and the fragrance components.

[0022] Such suction optimization means and gas generation sustaining material respectively mean the following structures and materials. The suction optimization means is a structure for improving the suction amount of the mouthpiece and a structure for preventing and supplementing the generation of dropped objects and dust such as non-tobacco materials from the heated aromatic generating body. More specifically, it means a cavity for improving the suction amount by expanding the gas flow path provided in the filter constituting the mouthpiece, a shape reinforcement member for preventing a decrease in the suction amount due to deformation provided in a support for preventing the movement of the heated aromatic generating body constituting the mouthpiece toward the mouthpiece side, a heat insulating material for preventing damage to the joint due to heat diffusion provided in the mouthpiece, and a lid material for preventing the generation of dropped objects and dust such as non-tobacco materials and a partition material for supplementing. The gas generation sustaining material is a material that does not block the flow path of the gas released from the heated aromatic generating body. More specifically, it is a heated aromatic generating base material whose internal structure is improved by a manufacturing method, a heated aromatic generating base material constituting a heated aromatic generating body with an optimized blending amount, inorganic particles present inside and / or on the surface of the heated aromatic generating base material constituting the heated aromatic generating body, and a heated aromatic generating base material with an improved filling rate. Hereinafter, these structures and materials of the present invention will be described in detail.

[0023] First, in the aromatic cartridge of the present invention, the filter is formed by shaping fibers into a cylindrical shape and constitutes all or part of the mouthpiece. The suction optimization means has a cavity provided so as not to penetrate longitudinally within the filter. This filter is a filter formed of generally used polyester fibers such as cellulose acetate (CA) fibers and polyethylene terephthalate (PET). In the case of an aromatic cartridge of a heated aromatic generator using a non-tobacco material, since the gas flow rate inhaled by a general smoker is not sufficient, the suction amount is improved by the cavity.

[0024] The shape and quantity of the cavity are not particularly limited and may be appropriately determined according to the type of the heated aromatic generator. However, considering the effect of increasing the amount of gas inhaled by a general smoker and the difficulty of the manufacturing method of the cavity, it is preferable that at least one is disposed at one end or both ends in the longitudinal direction of the filter.

[0025] Also, the position where the cavity is formed is arranged so that the inhaled gas enters the entire oral cavity uniformly when the smoker inhales. When there is one cavity, it is preferably formed on the central axis of the cylinder existing in the longitudinal direction of the filter. When there are two cavities, it is preferably formed with the central axis of the cylinder existing in the longitudinal direction of the filter as the center of the object. Further, when there are three or more filters, it is preferably disposed on the central axis of the cylinder existing in the longitudinal direction of the filter, and at positions rotationally symmetric about the central axis of the cylinder existing in the longitudinal direction of the filter and the central axis of the cylinder existing in the longitudinal direction of the filter.

[0026] Furthermore, regarding the shape of the cavity, from the viewpoints of increasing the amount of air inhaled by an average smoker and the difficulty level of the cavity manufacturing method, it is preferably columnar or conical. However, the shape of the bottom surface of the columnar or conical shape is not limited. However, since these cavities can be efficiently formed by general mechanical drilling, electrical discharge machining, or laser machining, from the viewpoint of workability, a cylindrical or conical shape is preferred.

[0027] Such a filter may constitute the entire mouthpiece alone 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 body. And the arrangement of the filter and the cavity is not particularly limited, and the heated aromatic body and the filter may be adjacent, or the heated aromatic body and the cavity may be adjacent. The cartridge exterior body is usually made of a thin film such as a polyolefin resin such as PE or PP, a PET resin, a CA resin, and polylactic acid (PLA), as well as thin paper, etc. However, when forming a cavity with the cartridge exterior body, although it depends on the material, a thickness sufficient to maintain the strength as a mouthpiece is required.

[0028] Furthermore, members having preferable functions other than the filter can be provided in the mouthpiece to improve the function of the mouthpiece. Such typical members generally include a support member for preventing the movement of the heated aromatic generator in the direction of the mouthpiece, and a cooling member for promoting the generation of smoke by cooling after the aerosol former of the heated aromatic generator volatilizes and lowering the temperature of the gas, and they may constitute the mouthpiece together with the filter. Such members may be applied alone or both. When applying only one of them, it is disposed between the heated aromatic generator and the filter. When applying both, the support member and the cooling member are disposed in this order or in the reverse order between the heated aromatic generator and the filter.

[0029] Note that the reason for reducing the temperature of the gas 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 within an extremely short distance between the heating part of the aromatic cartridge and the mouthpiece compared to a cigarette, so that a comfortable smoking experience can be enjoyed in the mouth. Therefore, the cooling member preferably serves as a heat exchanger, and a cylindrical porous body having continuous pores with a high porosity, a cylindrical tube provided with a large number of through holes, etc. are used. The porosity needs to be at least 50% or more, and preferably 70 to 90%. As materials, polyolefin resins such as PE and PP, PET resin, CA resin, polylactic acid (PLA), etc. have been used, but those with a metal foil such as aluminum with high thermal conductivity wound around them, and those made of metal itself are more preferable.

[0030] Thus, the mouthpiece enables a smoker to easily hold the aromatic cartridge in the mouth, and has a filter that filters the gas and softens the taste of the gas as an essential component. If necessary, a support member and / or a cooling member can be arranged. Utilizing this structure, since the filter is what obstructs the suction of the gas, it becomes possible to increase the suction amount by shortening the length of the filter. Therefore, instead of providing the cavity as described above, a structure of the mouthpiece that shortens the filter to increase the suction amount was considered.

[0031] Since the length of the aromatic cartridge itself and the length of the heated aromatic generator are determined according to the structure of the heat-not-burn smoking device, when shortening the filter of the mouthpiece, a structure is adopted in which a part of the filter is replaced with a support member. Conventionally, while the support member prevents the heated aromatic generator from moving in the mouthpiece direction, it cannot prevent the passage of gas. Therefore, it has a hollow cylindrical structure with a thin side thickness, and as materials, inexpensive polyolefin resins such as polyethylene (PE) and polypropylene (PP), plastics such as CA resin, and paper have been used. And in order not to prevent the passage of gas, it is preferably hollow and the thinner the side thickness of the support member is. However, when the filter is shortened and the length of such a support member is increased, a problem occurs that the mouthpiece is easily deformed.

[0032] In view of this problem, the present invention provides a structure of a support member that, in an aromatic cartridge including a mouthpiece composed of at least a filter and a support member, even when the length of the support member is increased and the side thickness is reduced, the mouthpiece does not deform and the suction amount is not decreased.

[0033] That is, in this aromatic cartridge, the mouthpiece has a support member including a through hole that prevents the heated aromatic generator from moving in the mouthpiece direction, and the central axes of the support member and the cylinder of the through hole are substantially the same. The suction optimization means includes a shape reinforcing member fixedly or movably disposed in the through hole. More specifically, this shape reinforcing member has the axes of the support member and its through hole in a plane and includes at least one or more plate-like members that contact the inner wall of the through hole. By disposing such a plate-like member in the cylindrical through hole of the support member, even when the length of the cylindrical support member is increased and the side thickness is reduced, it is not necessary to change the material, and it becomes possible to prevent the support member from deforming. The shape of this plate-like member is preferably a cross section cut in the axial direction of the cylinder, that is, a rectangle. From the viewpoint of the suction amount, the thinner the thickness is, the better, and the smaller the number is, the better. However, considering the viewpoint of preventing deformation, it is preferably 2 to 4 sheets of polyolefin resin with a thickness of 0.1 to 0.5 mm.

[0034] Furthermore, it is more preferable for preventing deformation of the support member that the shape reinforcing member includes a concentric cylinder having a radius smaller than the radius of the through-hole having substantially the same axis as the central axis of the cylinder of the support member and the through-hole, and a plate-like member formed so as to contact the inner wall of the through-hole in the radial direction of the concentric cylinder on the outer peripheral side of the concentric cylinder. 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 to which a mouthpiece including a support member provided with a shape reinforcing member for preventing the movement of the heated aroma generator in the mouthpiece direction adjacent to the heated aroma generator and a filter adjacent to the support member is applied, gas suction can be optimized without deformation of the support body. However, in order to more widely control gas suction, it is more preferable to apply a filter having a cavity as the filter. Furthermore, a cooling member capable of efficiently turning the volatilized aerosol perfume into aerosol smoke can also be disposed between the filter and the support member. In any of these cases, in order to more optimize the suction amount, it is preferable to apply a filter having a cavity as the filter.

[0036] On the other hand, as the suction amount increases due to improvements in the filter and the support member, the heat of the gas easily convects from the heating element to the filter, so the bonding force between the members constituting the aroma cartridge may decrease. Such joint surface locations vary depending on the configuration of the aroma cartridge, and examples include the interfaces between the heated aroma generator and the filter, the support member, the cooling member, and the cartridge exterior, the interfaces between the filter and the support member, the cooling member, and the cartridge exterior, the interfaces between the support member and the cooling member and the cartridge exterior, and the interface between the cooling member and the cartridge exterior.

[0037] When the bonding strength of each interface decreases in this way, gas will leak and affect the suction volume. Therefore, 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 like a sponge with continuous holes having a long flow path, rather than allowing the high-temperature gas to spread throughout like a supporting member adjacent to the heated aroma body, as long as it has a function of somewhat retaining and cooling the gas. Therefore, the length of the heat insulating member is extremely short, and there is no need for a cooling function up to the cooling member. It is preferably applied as a substitute for the supporting member that prevents the heated aroma generating body from moving in the direction of the mouthpiece.

[0038] Also, in the case of a heating type smoking device (FIG. 3) where the heating element covers the chamber, rather than a general heating type smoking device (FIG. 2) having a needle-shaped heating element at the bottom of the chamber, the influence of heat on the aroma cartridge is greater, and the decrease in the bonding strength of each member interface as described above is significant. Therefore, it is necessary to provide a heat insulating member to prevent the decrease in the bonding strength, that is, the reduction in the suction volume. Thus, from the perspective of eliminating the influence of the heat of the heating element and preventing the reduction in the suction volume, the present invention also provides an aroma cartridge having a heat insulating member interposed between the heated aroma generating body and the mouthpiece as suction optimization means.

[0039] Furthermore, since the heated aroma generating base material emits various aromas, the fiber component may be extremely reduced in some cases. In such a case, adjustments such as the blending amount of the binder are made, but in order to maintain the aroma, the blending ratio of non-tobacco materials cannot be significantly reduced, and the generation of dropout materials and dust such as non-tobacco materials is more likely to occur than usual. These are carried in the direction of the mouthpiece by smoking, which causes the voids of the filter and the cooling member to be clogged, resulting in an extremely reduced suction volume. Also, in the case of a heated aroma generating base material with such a formulation, dropout materials and dust are likely to be generated even when the aroma cartridge is pierced 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, or the like, which is a liquid at normal temperature, the more the binder is added, the more likely it is to bleed out from the heated aroma-generating base material over time, and the heated aroma-generating base materials fuse together, closing the flow path between the heated aroma-generating base materials and making it difficult to suck the suction component. Further, when such fusion occurs, it becomes difficult not only to insert the heating element into the heated aroma-generating base material, but also the heating element may be damaged. Conversely, if the addition amount of the binder or the like is reduced and a gas flow path is ensured, the non-tobacco material may fall off, dust may be generated, and it is difficult to firmly maintain the form of the aroma cartridge, and it may be destroyed when inserted into the heating element. Further, there is also a case where these are sucked into the oral cavity.

[0044] Therefore, in the present invention, first, it has been found that the above problems can be solved by the manufacturing method [apparatus] of the heated aroma-generating base material. In the following, mainly the manufacturing method including each step will be described, but it is obvious that there is a manufacturing apparatus that can implement the manufacturing method as a whole by providing means for executing each step. For this reason, without duplicating the description of the manufacturing method and the manufacturing apparatus, the description will be made simultaneously (overlapping) as "step [means]" and "method [apparatus]".

[0045] Now, the reason why the above problems can be solved by the manufacturing method [apparatus] of the heated aroma-generating base material is that the heated aroma-generating base material is a composition in which a material selected from non-tobacco materials, aerosol formers, binders, anti-adhesion agents, fragrances, non-tobacco material extracts, antibacterial preservatives, etc. is dispersed or dissolved in a medium such as pure water and alcohol, and after drying a sheet formed by a papermaking method, a compression molding method such as roll pressing or pressing, and a casting method, etc., and then cutting it. It is considered that this is because the internal structure of the heated aroma-generating base material varies depending on the manufacturing method [apparatus] in the forming and drying steps [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] In the aromatic cartridge of the present invention, the material for stabilizing the gas emission amount of the heated aromatic generator, that is, the gas generation sustaining material, first includes a dry mixing step [means] of mixing dried and pulverized non-tobacco materials, and the non-tobacco materials produced in the dry mixing step [means], and an aerosol former, a binder or thickener, crosslinked polyvinylpyrrolidone (PVP), a fragrance, a non-tobacco extract, β-cyclodextrin, microcrystalline cellulose, and a material selected from antibacterial preservatives are mixed in an alcohol and pure water mixture in a first wet mixing step [means]. Then, pure water and / or alcohol are further added to the alcohol and pure water mixture containing the non-tobacco materials and the like produced in the first wet mixing step [means] to produce a slurry containing the non-tobacco materials and the like in a second wet mixing step [means]. Next, a paper-making step [means] is used to produce a water-containing sheet from the slurry produced in the second wet mixing step [means]. Then, a sheet forming step [means] is used to compress the water-containing sheet into a sheet. After that, a drying step [means] is used to dry the sheet produced in the sheet forming step [means] to produce a heated aromatic generating sheet. Finally, a sheet processing step [means] is used to cut or bend the heated aromatic generating sheet. It is a heated aromatic generating base material produced from these steps.

[0050] The feature of the production in this method [apparatus] lies in the second wet mixing. By this second wet mixing with the addition of pure water and alcohol, the dispersion state of the aerosol former such as polypropylene glycol or glycerin and the non-tobacco materials is improved. Therefore, without increasing the addition amount of the binder, the lump state of the heated aromatic generating base material can be stabilized, and the bleed-out of the aerosol former can be reduced. In particular, for alcohol, lower monoalcohols such as ethanol and propanol are effective and preferred, and the addition amount is preferably 0.1 to 10 parts by mass with respect to 100 parts by mass of the non-tobacco materials.

[0051] The gas generation sustaining material in the second aromatic cartridge of the present invention is produced by a dry mixing step [means] of mixing dried and pulverized non-tobacco materials, the non-tobacco materials produced in the dry mixing step [means], and a material selected from an aerosol former, a binder or thickener, crosslinked PVP, a flavor, a non-tobacco extract, β-cyclodextrin, microcrystalline cellulose, and an antibacterial preservative in a mixed solution of alcohol and pure water in a first wet mixing step [means]; adding pure water and / or alcohol to the mixed solution of alcohol and pure water containing the non-tobacco materials and the like produced in the first wet mixing step [means] to produce a slurry containing the non-tobacco materials and the like in a second wet mixing step [means]; producing a water-containing sheet from the slurry produced in the second wet mixing step [means] in a papermaking step [means]; forming the water-containing sheet into a sheet by compression or casting in a sheet forming step [means]; applying or dipping an aerosol former to the water-containing sheet with a water content reduced to less than 50% by mass in an aerosol former absorption step [means] by the sheet forming step [means]; drying the sheet produced in the aerosol former absorption step [means] to produce a heated aromatic generating sheet in a drying step [means]; and a sheet processing step [means] of cutting or bending the heated aromatic generating sheet. It is a heated aromatic generating base material produced therefrom.

[0052] The features of the production of this method [apparatus] also lie in the second wet mixing. For the alcohol, lower monoalcohols such as ethanol and propanol are preferred, and the addition amount is preferably 0.1 to 10 parts by mass with respect to 100 parts by mass of the non-tobacco material, which is the same as in the first production method [apparatus]. However, the feature of the second production method [apparatus] is further that an aerosol former absorption step [means] is added in which an aerosol former is applied or immersed in a water-containing sheet with the water content reduced to less than 50% by mass. In the conventional production method [apparatus], the dispersion state of the aerosol former and the non-tobacco material was poor, and in the undried heated aroma-generating base material sheet with a water content of less than 50% by mass, the aerosol former and the non-tobacco material were free, making it difficult to absorb the aerosol former. However, since the dispersion state is improved by the second wet step [means], in the aerosol former absorption step [means], the aerosol former is absorbed into the sheet interior. Therefore, even if the addition amounts of the aerosol former and the binder are the same as in the first production method [apparatus], the lump state of the heated aroma-generating base material can be stabilized, the bleed-out of the aerosol former can be reduced, and in addition, the aerosol former becomes more volatile by heating.

[0053] The gas generation sustaining material in the third aromatic cartridge of the present invention includes a wet mixing step [means] of mixing dried and pulverized non-tobacco material with pure water to produce a slurry of 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 water content of the sheet produced in the sheet forming step [means] to less than 50% by mass, and applying or dipping the sheet produced in the drying step [means] with an alcohol and pure water mixture of a material selected from an aerosol former, a binder or thickener, crosslinked PVP, a fragrance, a non-tobacco extract, β-cyclodextrin, microcrystalline cellulose, a concentrated solution of the water discharged in the sheet forming step [means], and an antibacterial preservative, an absorption and adsorption step [means], a drying step [means] of drying the sheet produced in the absorption and adsorption step [means] to produce a heat-generating aromatic sheet, and a sheet processing step [means] of cutting or bending the heat-generating aromatic sheet, and is a heat-generating aromatic base material produced therefrom.

[0054] The first and second manufacturing methods [devices] formed a water-containing sheet by papermaking from a slurry in which all materials such as non-tobacco materials were wet-mixed with pure water and alcohol. However, the third manufacturing method [device] is characterized in that a water-containing sheet is produced from a slurry of non-tobacco material alone, and other materials such as an aerosol former are absorbed and adsorbed onto the dried sheet. In the first and second manufacturing methods [devices], there was a problem in wet-dispersing all the materials itself, as if the dispersion of non-tobacco material and aerosol former was improved. Therefore, as a result of studying a manufacturing method [device] that does not go through the step [means] of mixing and dispersing non-tobacco material and aerosol former, it was found that a pure water and alcohol mixture of other materials such as an aerosol former quickly penetrates, is absorbed and adsorbed onto the dried non-tobacco material sheet, as in the third manufacturing method [device], and the present invention was achieved. The bulk state of the heat-generating aromatic base material produced by this method [device] is stable, and the bleed-out of the aerosol former is also reduced.

[0055] The gas generation sustaining material in the fourth aromatic cartridge of the present invention is produced through the following steps: a non-tobacco material preparation step [means] of drying and pulverizing non-tobacco materials; a flavor and / or non-tobacco extract mixture step [means] of mixing at least a flavor and / or non-tobacco extract, crosslinked PVP, and / or β-cyclodextrin in alcohol to retain the flavor and / or non-tobacco extract in the crosslinked PVP and / or β-cyclodextrin; an aerosol former dissolution step [means] of mixing at least an aerosol former and a binder or thickener in pure water; a wet mixing step [means] of mixing the material produced in the non-tobacco material preparation step [means], the material produced in the flavor and / or non-tobacco extract dissolution step [means], and the material produced in the aerosol former dissolution step [means]; a sheet forming step [means] of compressing the material produced in the wet mixing step [means] to produce a heated aromatic generation sheet; and a sheet processing step [means] of cutting or bending the heated aromatic generation sheet. It is a heated aromatic generation base material produced from these steps.

[0056] Previously, the manufacturing method [apparatus] was characterized by forming a sheet from a slurry of non-tobacco materials or the like through a papermaking process [means]. However, in view of the results of the third manufacturing method [apparatus], there are problems with casting a sheet from slurries of materials with different properties such as non-tobacco materials. Therefore, without passing through a large amount of pure water and alcohol slurries, a sheet of the heated aromatic generation base material is formed using a roll press such as a three-roll press for a mixture of non-tobacco materials or the like with little pure water and alcohol and high viscosity. In this method [apparatus], since a large shearing force and compressive force are applied to the mixture of non-tobacco materials or the like, it is considered that all materials are uniformly kneaded and dispersed.

[0057] Here, there is a mixing step [means] of mixing at least a fragrance and / or a non-tobacco material extract with crosslinked PVP and / or β-cyclodextrin in alcohol to retain the fragrance and / or non-tobacco extract in the crosslinked PVP and / or β-cyclodextrin, and an aerosol former dissolving step [means] of mixing at least an aerosol former with a binder or a thickener in pure water. It is important to pre-dissolve materials such as fragrances, non-tobacco material extracts, aerosol formers, binders or thickeners that can be dissolved in pure water and alcohol. In particular, when using menthol and / or xylitol as fragrances, these are adsorbed by the crosslinked PVP and / or β-cyclodextrin, stably present in the heated aroma-generating base material, and have the effect of suppressing the bleed-out of the aerosol former. Therefore, the mixing step [means] of mixing at least a fragrance and / or a non-tobacco material extract with crosslinked PVP and / or β-cyclodextrin in alcohol to retain the fragrance and / or non-tobacco extract in the crosslinked PVP and / or β-cyclodextrin plays an extremely important role.

[0058] By adopting this manufacturing method [apparatus], the lump state of the heated aroma-generating base material is stable, the bleed-out of the aerosol former can be significantly reduced, there is no fusion of the heated aroma-generating base material, the volatilization of gas due to the heating of the heated aroma-generating body is promoted, and a decrease in the suction amount 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, crosslinked PVP, fragrances, non-tobacco extracts, β-cyclodextrin, microcrystalline cellulose, antibacterial preservatives, and pure water. This step [means] can promote kneading by shear force and compressive 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 aromatic cartridge of the present invention is produced by a first wet mixing step [means] of mixing dried and pulverized non-tobacco material, a first binder aqueous solution obtained by dissolving a first binder in pure water, an aerosol former, crosslinked PVP, a fragrance, a non-tobacco material extract, β-cyclodextrin, microcrystalline cellulose, and a material selected from antibacterial preservatives; a curing step [means] of stabilizing the mixed solution produced in the first wet mixing step [means]; a second wet mixing step [means] of mixing the cured mixed solution produced in the curing step [means] and a second binder aqueous solution obtained by dissolving a second binder in pure water; a sheet forming step [means] of compressing the material produced in the second wet mixing step [means] to produce a heatable aromatic generation sheet; and a sheet processing step [means] of cutting or bending the heatable aromatic generation sheet. Also, in this manufacturing method [device], similar to the fourth manufacturing method [device], in the sheet forming step [means], it is preferable to add a step [means] of adding a material selected from non-tobacco material, aerosol former, binder or thickener, crosslinked PVP, fragrance, non-tobacco extract, β-cyclodextrin, microcrystalline cellulose, antibacterial preservative, and pure water.

[0061] This manufacturing method [device] is particularly characterized by providing a step [means] of curing the mixed solution and a step [means] of adding the binder in two divided portions before and after the curing step [means]. And for the binder, a modified cellulose-based polymer is preferably used for the first time, and a polysaccharide-based polymer other than cellulose is preferably used for the second time.

[0062] The curing step [means] means that the dispersion state of the mixture such as non-tobacco material changes over time, and it is presumed that it leads to the most stable and uniform dispersion state with the lowest energy. This state change is considered to be able to form the massive state of the heatable aromatic generation base material.

[0063] Also, by adding the binder in two portions, the mixture can be sufficiently dispersed even when the amount of the binder added is reduced, and the viscosity can be easily adjusted. This is closely related to the curing process [means]. By adding the first portion of the binder and curing, a stable dispersed state is created, making it easier to add the second portion of the binder, reducing the amount added, and facilitating viscosity adjustment. Therefore, a modified cellulose-based polymer with superior dispersing ability is preferred for the first addition, and a polysaccharide-based polymer other than cellulose with superior ability as a thickener for adjusting viscosity is preferred for the second addition.

[0064] As such modified cellulose-based polymers, it is preferable to use any one or more of methyl cellulose, ethyl cellulose, carboxymethyl cellulose, carboxyethyl cellulose, hydroxymethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, and the sodium salt, potassium salt, and calcium salt of carboxymethyl cellulose and carboxyethyl cellulose. As polysaccharide-based polymers, it is preferable to use any one or more of konjac mannan (glucomannan), guar gum, pectin, carrageenan, tamarind seed gum, gum arabic, soy polysaccharide, locust bean gum, karaya gum, xanthan gum, and agar.

[0065] And, the compounding amount of the binder is preferably 5 to 20 parts by mass of the first binder and 0.1 to 5 parts by mass of the second binder with respect to 100 parts by mass of the non-tobacco material.

[0066] There are also appropriate conditions for the curing process [means] that leads to a stable dispersed state, and it is preferably carried out at 15 to 30 °C for 72 to 336 hours. The appropriate temperature conditions are considered to be due to the fact that the binder is a polymer having a hydroxyl group or a carboxyl group, and the presence or absence of hydrogen bond formation causes a difference in the molecular state dissolved in pure water and alcohol, which depends on the temperature, and the optimal temperature range is derived as an experimental result. The dispersed state changes over time and requires a minimum amount of time to become stable, but there is no significant change even if it takes more time than necessary, which reduces productivity.

[0067] The above has described the solution means of optimizing, by means of a manufacturing method [apparatus], the material that stably releases gas from the heated aroma generator, that is, the heated aroma generating base material that becomes a gas generation sustaining material. However, a material that more actively and stably releases gas has been devised.

[0068] This gas generation sustaining material is inorganic particles. The effects of the inorganic particles are of two types depending on the location where they exist. One is the case where the inorganic particles are present inside the heated aroma filler. By adding the inorganic particles to the heated aroma generator, the density of the heated aroma generating base material is lowered, the gas flow path is prevented from being closed, and it becomes impossible for gas suction to be difficult. The other is the case where the inorganic particles are on the surface of the heated aroma generating sheet or the heated aroma generating base material. Even if the aerosol former bleeds out from the heated aroma generating base material over time, the inorganic particles can prevent the fusion phenomenon between the heated aroma generating base materials, the flow path between the heated aroma generating sheets or the heated aroma generating base materials is not closed, and the problem that it becomes difficult to suck the suction component is solved. Also, since the fusion of the heated aroma generating sheet or the heated aroma generating base material is eliminated, the problem that it becomes difficult to insert the heating element into the heated aroma generating base material is also solved. Furthermore, introducing inorganic particles into the heated aroma generator also has the effect of reducing the contact area between the heating element and the organic components of the heated aroma generating base material, whether inside or on the surface of the heated aroma generating base material, so that the dirt on the heating element of the heat-not-burn smoking device can be reduced.

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

[0070] On one hand, in order to be present on the surface of the heat-generating aromatic generating substrate, in the above-described five manufacturing methods [apparatuses], after the step [means] of manufacturing the heat-generating aromatic generating sheet, there is a step [means] of spraying inorganic particles onto the heat-generating aromatic generating sheet, and after the sheet processing step [means] of manufacturing the heat-generating aromatic generating substrate, there is a step [means] of spraying inorganic particles onto the heat-generating aromatic generating substrate.

[0071] Examples of the inorganic particles preferably include 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, silicon oxides such as zeolite, colloidal silica, and fumed silica, and more preferably, the average particle diameter is 1 to 100 μm. Further, in order for the inorganic particles to function effectively, it is preferable to add 0.1 to 10 parts by mass of the inorganic particles with respect to 100 parts by mass of the non-tobacco material.

[0072] As described above, the aromatic cartridge of the present invention includes a heat-generating aromatic generating body in which a heat-generating aromatic generating substrate in contact with a heating element is wound, a mouthpiece including a filter that filters the aerosol smoke and fragrance components generated by heating from the heating element, and a cartridge exterior body that wraps around the outer periphery so as to connect the heat-generating aromatic generating body and the mouthpiece. At least one of the heat-generating aromatic generating body and the mouthpiece has at least one of a means for optimizing the suction of smoke and fragrance components and a gas generation sustaining material for smoke and fragrance components. In the above, the suction optimization means and the gas generation sustaining material in the aromatic cartridge of the present invention have been described. Hereinafter, inventions that complement these will be further described.

[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] And microcrystalline cellulose is preferably 7 to 25 parts by mass with respect to 100 parts by mass of the non-tobacco material. This microcrystalline cellulose is a fluid 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 due to the high compressibility with large fluidity and volume change of microcrystalline cellulose, it is effective in preventing aggregation and breakage and preventing adhesion to the mold in the molding of tablets by the direct compression method. The same effect is also present in the heated aroma-generating substrate, and if the above blending amount is less than this, this function cannot be expressed. Conversely, if this blending amount is exceeded, the blending ratio of other materials is relatively insufficient, which has an adverse effect on the function as a heated aroma-generating substrate.

[0077] Finally, β-cyclodextrin is preferably 0.2 to 1.0 parts by mass with respect to 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 blending amount is required, but excessive addition inhibits the function as a heated aroma-generating substrate. In particular, it is known to include menthol, and when menthol is used as an aroma component, it is preferably added.

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

Advantages of the Invention

[0097] The aromatic cartridge provided with the suction optimization means of the present invention does not use any tobacco components and can solve the problem of reduced suction amount of the smoker's gas due to blockage of the gas flow paths inside and between the heat-generating aromatic substrates, which is a problem specific to aromatic cartridges using non-tobacco materials. On the other hand, in the aromatic cartridge provided with the gas generation sustaining material, the reduction in the gas release amount itself due to blockage of the gas flow path can be improved, and an aromatic cartridge without dropping of non-tobacco materials or the generation of dust can be provided.

[0098] In addition, the heated aroma generator provided with inorganic particles as the gas generation sustaining material of the present invention can prevent fusion between the heated aroma generating substrates, and solve the problem that an aroma cartridge stored for a long time cannot be attached to the heating element of a heat-not-burn smoking device, and the problem of damaging or contaminating the heating element.

Embodiments for Carrying out the Invention

[0100] Hereinafter, the present invention will be described in more detail with reference to the drawings and embodiments. However, the present invention is not limited thereto, and various modifications can be made without departing from the gist of the present invention, and it is limited only by the technical idea described in the claims.

[0101] FIG. 1 is a schematic diagram showing the general configuration and manufacturing method [apparatus] steps [means] of a cylindrical aromatic cartridge that is mounted in contact with the heating element of a heated smoking device having an electrically controlled heating element in a chamber and can enjoy the aerosol smoke and aroma components generated by heating the heating element. The aromatic cartridge of the present invention is basically configured and assembled in the same manner, except that it does not use any tobacco components as a heated aromatic generating body that generates an aerosol heated by a heating element. That is, in the aromatic cartridge of the present invention, a heated aromatic generating body in which a heated aromatic generating base material composed of a non-tobacco material and an aerosol former or the like is wound is in a state where the contact and the mouthpiece are adjacent in the longitudinal direction so that the heated aromatic generating body contacts an electrically controlled heating element, and the outside of the heated aromatic generating body and the mouthpiece are connected in a state of being wound by a cartridge exterior body.

[0102] FIGS. 2 and 3 show the state of smoking by mounting such an aromatic cartridge on a heated smoking device for two types of heating element formats. In order to clarify the characteristics of the aromatic cartridge of the present invention, a mechanism for enjoying the aromatic cartridge by mounting it on a heated smoking device will be briefly described.

[0103] FIG. 2(A) is a schematic cross-sectional view of an electrically heated smoking device (1) including 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 aromatic cartridge 2 in which a heated aromatic generating body 21 wound with an interior material 21-p and a mouthpiece 22 wound with an interior material 22-p are the heated smoking device (1). 11They are wound and connected by the cartridge exterior body 23 while being adjacent to each other in the longitudinal direction. And, in FIG. 2(C), a smoker uses the electric heating type smoking device (1) 11 to suck the aroma cartridge 2 . The state of sucking the aroma cartridge shown in FIG. 2(B) 2 is inserted into the chamber 112 with the heated aroma generating body 21 side, and the heated aroma generating body 21 is pierced by the electric control type heating element 113. When the smoker presses a switch (not shown), the electric control type heating element 113 is heated according to the signal of an electric control unit (not shown), and aerosol smoke and aroma components are released from the heated aroma generating body 21 and sucked. When the smoker sucks, as shown by the arrow W, air enters from the air inlet 115, passes through the gap between the casing 111 and the chamber 112, and the aerosol former and aroma components volatilized from the heated aroma generating body 21 are carried to the mouthpiece 22 and sucked into the smoker's oral cavity. The smoke is cooled in the mouthpiece 22 and sucked as an aerosol.

[0104] FIG. 3(A) is a schematic cross-sectional view of an electric heating type smoking device (2) 12 provided with an electric control type heating element 123 provided on the outer periphery of a chamber 122 housed in a casing 121. FIG. 3(B) shows a state where a smoker uses the electric heating type smoking device (2) 12 to suck the aroma cartridge 2 . When the heated aroma generating body 21 side of the aroma cartridge shown in FIG. 3(B) 2 is inserted into the chamber 122 from the aroma cartridge insertion port 124, the heated aroma generating body 21 is surrounded by the electric control type heating element 123. When a switch (not shown) is pressed, the electric control type heating element 123 is heated according to the signal of the electric control unit 1231, and aerosol smoke and aroma components are released from the heated aroma generating body 21 and sucked. When the smoker sucks, as shown by the arrow W, air enters from the air hole 125, and the aerosol former and aroma components volatilized from the heated aroma generating body 21 are carried to the mouthpiece 22 and sucked into the smoker's oral cavity. The smoke is cooled in the mouthpiece 22 and sucked as an aerosol.

[0105] In such smoking, an aroma cartridge composed only of non-tobacco materials has the advantage that it does not generate substances harmful to the human body, tar, and nicotine, and can enjoy various flavors such as beverages like coffee, cola, Red Bull, desserts like chocolate, vanilla, cream, fruits like orange, lemon, melon, and cooling agents like menthol, mint, herb, etc. However, as a substitute for tobacco materials containing a large amount of fibers, it has problems due to the use of a variety of non-tobacco materials for emitting various flavors.

[0106] In the aerosol-forming body containing tobacco materials, the fibers of the tobacco materials maintained their lump state and prevented the dropping and fusion of the tobacco materials. However, for a heated aroma-generating base material containing non-tobacco materials that do not contain a large amount of fibers, in order to stably maintain its lump state, it is necessary to blend a large amount of a binder or the like that performs the function of fibers. Therefore, the density of the heated aroma-generating base material becomes high, the gas flow path is blocked, and it becomes difficult to suck the suction component. As a result, the suction amount decreases.

[0107] In addition, since the aerosol former is glycerin, propylene glycol, etc. which are liquids at normal temperature, the more the binder increases, the more it bleeds out from the heated aroma-generating base material over time, and the heated aroma-generating base materials fuse together. Therefore, the gas flow path is blocked, and it becomes difficult to suck the aroma component. As a result, the suction amount decreases. Further, when such fusion occurs, not only does it become difficult to insert the heating element into the heated aroma-generating base material, but the heating element may also be damaged.

[0108] Conversely, if the addition amount of a binder or the like is reduced to secure a gas flow path, dropping of non-tobacco materials, dust, etc. will occur, and it will be difficult to firmly maintain the form of the aroma cartridge, and it may be broken when inserted into the heating element. Also, these may be sucked into the oral cavity.

[0109] The present invention aims to provide means for solving these problems. That is, it provides means for securing a gas flow path and preventing a decrease in the suction amount. Note that a solution method that greatly changes the composition and blending ratio of the composition constituting the heated aroma generating substrate cannot be adopted because it is necessary to maintain the generation of aerosol that becomes smoke and the generation of aroma components released from non-tobacco materials. Therefore, the present invention provides means for solving the problems from two different aspects.

[0110] One is a physical solution means that focuses on the structure of the mouthpiece and the like that constitutes the aroma cartridge and has a great influence on the suction amount. The other is a chemical solution means that focuses on the manufacturing method [apparatus] of the heated aroma generating substrate and its filling state and the like.

[0111] The former physical solution means is to provide an aroma cartridge equipped with suction optimization means for improving the suction amount in the mouthpiece, and to provide an aroma cartridge equipped with suction optimization means for preventing a decrease in the suction amount by supplementing the heated aroma generator with debris and dust such as non-tobacco materials. More specifically, it is to provide an aroma cartridge in which a filter constituting the mouthpiece, a support for preventing the movement of the heated aroma generator constituting the mouthpiece to the mouthpiece side, and a cavity for improving the suction amount by expanding the gas flow path, a shape reinforcing member for preventing a decrease in the suction amount due to deformation, and a heat insulating material for preventing damage to the joint due to heat diffusion are arranged in the mouthpiece as suction optimization means. Further, it is to provide an aroma cartridge in which a lid material and / or a partition material for preventing and capturing debris and dust such as non-tobacco materials is arranged in the heated aroma generator as suction optimization means.

[0112] The latter chemical solution is to provide an aromatic cartridge having a gas generation maintenance material that does not reduce the suction amount to the heated aroma generator. More specifically, for the heated aroma generator, as the gas generation maintenance material, 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 an aromatic cartridge provided with a heated aroma generating substrate with an improved filling rate are provided.

[0113] Since these suction optimization means and gas generation maintenance materials can each exhibit sufficient effects, FIG. 4 shows the configuration of an aromatic cartridge that joins a heated aroma generator without a gas generation maintenance material and a mouthpiece with suction optimization means, and FIG. 33 shows the configuration of an aromatic cartridge that joins a heated aroma generator with a gas generation maintenance material and a mouthpiece without suction optimization means. However, since a higher or broader effect can be obtained by using them in combination, it is possible to provide a very wide variety of aromatic cartridges with all combinations of the heated aroma generators and mouthpieces shown in FIGS. 4 and 33.

[0114] First, the suction optimization means will be described in detail with reference to the drawings. FIG. 5 shows a mouthpiece 221-1 composed of a single filter 221-1 for filtering gas in which one cavity 221-1-c1 is formed, adjacent to a heated aroma generator 21, and these are joined and wound by a cartridge exterior body 23. 2-1 The aromatic cartridge in which the cavity 221-1-c1 is arranged in the filter 221-1 at the end of the filter 221-1 on the side of the heated aroma generator 21 in the longitudinal direction of the filter 221-1 so that the central axis о of the straight circular cylinder of the filter 221-1 and the cavity 221-1-c1 is substantially the same. 2-1 is a schematic diagram showing it. For example, the outer diameters of the aromatic cartridge, the heated aroma generator, and the mouthpiece are as shown in FIGS. 2 and 3 for the heat-not-burn smoking device (1) 11 and (2) 12Since it is determined by [specific method], it can be set as appropriate. Hereinafter, the outer diameter j and the length k of the aromatic cartridge are 6.9 mm and 45 mm respectively, the length a of the heated aromatic generator is 12 mm, and the length m (= f) of the mouthpiece (= filter) is 33 mm.

[0115] The size of the cavity can increase the suction amount as it becomes longer and thicker. However, due to the problem of the strength of the mouthpiece, the length c1, the inner diameter b1, and the surface area are 10 - 25 mm, 1 - 4 mm, and 34.54 - 326.54 mm respectively. 2 It is preferably so. In one embodiment of FIG. 5, a straight circular cylindrical cavity with a length c1 of 20 mm and an inner diameter of 3 mm is formed. Also, although the straight circular cylindrical cavity is exemplified as the most preferable shape of the cavity, an oblique circular cylindrical shape may also be used and is not limited. Any hole that does not penetrate the filter may be used. However, considering the uniform gas suction into the oral cavity and workability, a symmetric shape centered on the central axis of the filter is preferable, and columnar shapes such as triangular prism, quadrangular prism, and pentagonal prism, as well as pyramidal shapes such as conical (FIG. 9), triangular pyramid, quadrangular pyramid, and pentagonal pyramid are preferable.

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

[0117] FIG. 6 shows a mouthpiece 221 - 2 composed of a single filter 221 - 2 for filtering gas in which two cavities 221 - 2 - c2 and 221 - 2 - c3 are formed according to an embodiment of the present invention, adjacent to a heated aromatic generator 21, and these are joined and wound by a cartridge exterior body 23. 2-2 It is an aromatic cartridge in which the cavities 221 - 2 - c2 and 221 - 2 - c3 are arranged in the filter 221 - 2 at both longitudinal ends of the filter 221 - 2 such that the central axes о of the straight cylinders of the filter 221 - 2 and the cavities 221 - 2 - c2 and 221 - 2 - c3 are substantially the same. 2-2It is a schematic diagram showing [the relevant part]. The shape of the cavity that can improve the suction volume can increase the suction volume as it is longer and thicker. However, due to the problem of the strength of the mouthpiece, it is preferable that the lengths c2 and c3 are 5 to 15 mm, and 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 is preferable. The shape is as described in the description of FIG. 5.

[0118] FIG. 7 shows a mouthpiece 221-3 composed of a filter unit 221-3 for filtering gas in which four cavities 221-3-c4 are formed according to an embodiment of the present invention, adjacent to a heated aromatic generator 21, and these are joined and wound by a cartridge exterior body 23, a straight cylindrical aromatic cartridge 2-3 wherein the cavity 221-3-c4 is straight cylindrical and is disposed at a rotationally symmetric position within the filter 221-3 from the end portion on the side of the heated aromatic generator 21 in the longitudinal direction of the filter 221-3 around the central axis of the straight cylinder existing in the longitudinal direction of the filter 221-3, an aromatic cartridge 2-3 is a schematic diagram showing [the relevant part]. In FIG. 7, as a preferable example, the case of four cavities is illustrated, but it is not limited thereto, and two or more are sufficient. The number and size of the cavities are appropriately set according to the balance between the suction volume and the strength of the filter, similar to the description in FIG. 6, but the total surface area is 34.54 to 326.54 mm 2 is preferably made to be. The shape is as described in the description of FIG. 5. Also, the cavity in FIG. 7 is also formed at the end portion on the side of the heated aromatic generator in the longitudinal direction of the filter, but it may be provided at the end portion on the opposite side of this end portion.

[0119] FIG. 8 shows a mouthpiece 221-4 composed of a filter unit 221-4 for filtering gas in which five cavities 221-4-c5 and 221-4-c6 are formed according to an embodiment of the present invention, adjacent to a heated aromatic generator 21, and these are joined and wound by a cartridge exterior body 23, a straight cylindrical aromatic cartridge 2-4wherein all the cavity shapes are straight circular cylindrical, and four cavities 221-4-c5 are arranged in rotationally symmetric positions in the filter 221-4 from the end on the heated aromatic generator 21 side in the longitudinal direction of the filter around the central axis of the straight circular cylinder existing in the longitudinal direction of the filter 221-4, and one cavity 221-4-c6 is arranged in the filter from the end on the side opposite to the heated aromatic generator 21 in the longitudinal direction of the filter 221-4 so that the central axes of the straight circular cylinders of the filter 221-4 and the cavity 221-4-c6 are substantially the same, an aromatic cartridge 2-4 is a schematic diagram showing this. In FIG. 8, as an example, four cavities 221-4-c5 at the end on the heated aromatic generator side of the filter and five cavities 221-4-c6 on the opposite side are shown, but their numbers and sizes are not limited to these, and as described in the description of FIG. 6, they are appropriately set according to the balance between the suction amount and the strength of the filter, but the total surface area is 34.54 to 326.54 mm 2 It is preferable to make it like this. The shape is as described in the description of FIG. 5.

[0120] FIG. 9 shows a modified example of the cavity shape. In the aromatic cartridge 2-1 shown in FIG. 5, the cavity 221-5-d1 is a straight conical shape. Also in this case, the dimensions of the straight conical cavity can be appropriately designed so that the surface area is 34.54 to 326.54 mm 2 In FIG. 9, the cavity is formed at the end on the heated aromatic generator 21 side in the longitudinal direction of the filter, but it may be provided at the end on the side opposite to this end.

[0121] FIG. 10 also shows a modified example of the cavity shape. In the aromatic cartridge shown in FIG. 7 2-3 three straight conical cavities 221-6-d2 are provided. Also in this case, the number and dimensions of the straight conical cavities can be appropriately designed so that the surface area is 34.54 to 326.54 mm 2 In this case as well, the cavity is formed at the end on the heated aromatic generator side in the longitudinal direction of the filter, but it may be provided at the end on the side opposite to this end.

[0122] Figure 11 shows a mouthpiece 221-7 composed of a filter 2211 for filtering gas in which one cavity 221-7-c7 is formed and a cavity 221-7-v1 formed by a cartridge outer body 24, in an aromatic cartridge in a straight cylindrical shape in which a heated aromatic generator 21 and the filter 2211 are adjacent to each other and are joined and wound by the cartridge outer body 24. 2-7 The cavity 221-7-c7 is in a straight cylindrical shape and is disposed in the filter 2211 from the end on the side of the heated aromatic generator 21 in the longitudinal direction of the filter 2211 so that the central axes of the straight cylinders of the filter 2211 and the cavity 221-7-c7 are substantially the same. Figure 11 shows that the heated aromatic generator and the filter are adjacent to each other, but the arrangement is not limited to this, and conversely, the heated aromatic generator and the cavity may be adjacent to each other. In this case, since the suction amount increases due to the shortening of the length f of the filter, the number and size of the cavities formed in the filter, that is, the surface area can be reduced. Since only the cartridge outer body needs to have the strength as a mouthpiece, the thickness of polyolefin resins such as PE and PP, PET resin, CA resin, and polylactic acid (PLA), etc., which are the materials of the cartridge outer body, and paper, etc. may be appropriately increased according to the material.

[0123] Figure 12 shows a mouthpiece 221-8 composed of a filter 2212 for filtering gas in which four cavities 221-8-c8 are formed and a cavity 221-8-v2 formed by the outer body of the cartridge, in an aromatic cartridge in a straight cylindrical shape in which a heated aromatic generator 21 and the filter 2212 are adjacent to each other. 2-8It is a schematic diagram in which the cavity 221-8-c8 is in a straight circular column shape and is disposed at a rotationally symmetric position in the filter 2212 from the end portion on the side of the heated aromatic generator 21 in the longitudinal direction of the filter 2212 into the filter 2212 around the central axis of the straight circular column existing in the longitudinal direction of the filter 2212. Also in this case, similar to the description of FIG. 11, the heated aromatic generator and the cavity may be adjacent to each other. Since the length f of the filter becomes short and the suction amount increases, the number and size of the cavities formed in the filter, that is, the surface area can be reduced. Also, the strength of the cartridge exterior is the same as that of FIG. 11.

[0124] A filter provided with such a cavity is also extremely effective as a suction optimization means for solving the reduction in the suction amount of a mouthpiece provided with a conventional general support member and / or cooling member.

[0125] FIG. 13 is a schematic diagram showing an aroma cartridge 2-9 according to an embodiment of the present invention. A mouthpiece 222 is provided with a columnar support member 2221 for preventing the heated aromatic generator 21 from moving in the direction of 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 aromatic body 21, and these are joined and wound by a cartridge exterior 24. The cavity 2222-c1 is disposed in the filter 2222 from the end portion on the side of the support member 2221 in the longitudinal direction of the filter 2222 so that the central axes of the straight circular columns of the filter 2222 and the cavity 2222-c1 are substantially the same. Also in this case, the number, size, and shape of the cavity are not limited to those in FIG. 13, and those described in the description of FIGS. 6 to 10 can be applied. However, since the support member is substantially a cavity, the number and size of the cavities can be considerably reduced.

[0126] FIG. 14 is a schematic diagram showing an aromatic cartridge 2-10 according to an embodiment of the present invention. A cylindrical support member 2231 that prevents the adjacent heated aromatic generating body 21 from moving in the direction of the mouthpiece 223, a cylindrical cooling member 2232 that cools the components volatilized when the adjacent heated aromatic generating body 21 is heated, and one cavity 2223-c1 adjacent to the cooling member 2232 and having a filter 2223 for filtering gas are provided. The mouthpiece 223 is adjacent to the heated aromatic body 21, and these are joined and wound by the cartridge exterior body 23. The cavity 2223-c1 is disposed in the filter 2223 from the end portion of the filter 2223 on the cooling member 2232 side in the longitudinal direction so that the central axes of the straight cylinders of the filter 2223 and the cavity 2223-c1 are substantially the same. Also in this case, the number, size, and shape of the cavities are not limited to 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 aromatic cartridge 2-11 according to an embodiment of the present invention. A cylindrical cooling member 2241 that cools the components volatilized when the adjacent heated aromatic generating body 21 is heated, and a filter 2242 having one cavity 2242-c1 adjacent to the cooling member 2241 and filtering gas are provided. The mouthpiece 224 is adjacent to the heated aromatic body 21, and these are joined and wound by the cartridge exterior body 23. The cavity 2242-c1 is disposed in the filter 2242 from the end portion of the filter 2242 on the cooling member 2241 side in the longitudinal direction so that the central axes of the straight cylinders of the filter 2242 and the cavity 2242-c1 are substantially the same. Also in this case, the number, size, and shape of the cavities are not limited to 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 also described in the descriptions of FIGS. 13 and 14, the solution means of the present invention for the problem of deformation of the mouthpiece when a filter, a support member, and / or a cooling member are arranged in the mouthpiece and the length of the support member is increased to increase the suction amount will be specifically described. Here, in order to eliminate the decrease in the gas suction amount by preventing the deformation of the mouthpiece, the shape reinforcing member of the mouthpiece serves as the suction optimization means.

[0129] FIG. 16 is a schematic diagram showing an aroma cartridge 2-12 according to an embodiment of the present invention for preventing deformation of the mouthpiece. A mouthpiece 225-1 having a support member 2251-1 for preventing the adjacent heated aroma generator 21 from moving in the direction of the mouthpiece 225-1 and a filter 2252-1 for filtering gas adjacent to the support member 2251-1 is adjacent to the heated aroma body 21, and these are joined and wound by a cartridge exterior body 23. The suction optimization means in this case is a single plate-shaped reinforcing material 2252-1-s1 that contacts the inner wall of the through-hole 2251-1-h, and is arranged in the through-hole 2251-1-h formed so that the central axis of the support member 2251-1 and the central axis of the straight cylinder are substantially the same, with the central axis in the plane and arranged fixedly or movably. By thus supporting the support member from the inside of the through-hole with the plate-shaped reinforcing material, deformation of the support member can be prevented, and a decrease in the suction amount can be prevented. And this plate-shaped reinforcing material may be fixed with an adhesive by forming a groove in the through-hole, for example, or may be simply inserted into the through-hole so as to be movable, but is not limited to this method.

[0130] FIG. 17 is a schematic diagram showing an aroma cartridge 2-13 according to an embodiment of the present invention for preventing deformation of a mouthpiece. A mouthpiece 225-2 including a support member 2251-2 for preventing the movement of an adjacent heated aroma generator 21 in the direction of the mouthpiece 225-2 and a filter 2252-2 adjacent to the support member 2251-2 for filtering gas is adjacent to the heated aroma body 21, and these are joined and wound by a cartridge exterior body. The suction optimization means is a plate-shaped reinforcing material 2251-2-s2 in which two plate-shaped members in contact with the inner wall of the through-hole 2251-2-h included in the reinforcing support member 225-2 intersect, and is disposed in the through-hole 2251-2-h formed so that the central axis of the support member 2251-2 and the central axis of the straight cylinder are substantially the same, with its central axis in the plane and fixed or movable. Since this plate-shaped reinforcing material can prevent deformation more strongly than the plate-shaped reinforcing material shown in FIG. 16, it is possible to further increase the length of the support member and prevent a decrease in the suction amount. As the fixed or movable arrangement method, for example, the method described in FIG. 16 can be directly applied, but it is not limited thereto.

[0131] FIG. 18 is a schematic diagram showing an aroma cartridge 2-14 according to an embodiment of the present invention for preventing deformation of the mouthpiece. A mouthpiece 225-3 including a support member 2251-3 for preventing the movement of an adjacent heated aroma generator 21 in the direction of the mouthpiece 225-3 and a filter 2252-3 for filtering gas adjacent to the support member 2251-3 is adjacent to the heated aroma body 21, and these are joined and wound by a cartridge exterior body 23. The suction optimization means is a shape reinforcing material including a tubular reinforcing material 2251-3-s4 fixedly or movably arranged as a reinforcing support member 2251-3 and four plate-shaped reinforcing materials 2251-3-s3. The tubular reinforcing material 2251-3-s4 is a concentric tube having a radius smaller than the radius of a through hole 2251-3-h of the support member 2251-3 formed so that the central axis of the straight cylinder is substantially the same as that of the support member 2251-3 and having an axis substantially the same as this axis. Further, the four plate-shaped reinforcing materials 2251-3-s3 are formed on the outer peripheral side and in the radial direction of the tubular reinforcing material 2251-3-s4 so as to contact the inner wall of the through hole 2251-3-h. The shape reinforcing material composed of this tubular reinforcing material and plate-shaped reinforcing material has a greater reinforcing effect than the plate-shaped reinforcing material shown in FIG. 17, and the length of the support member can be further increased. Also in this case, the fixed or movable arrangement method is the same as that in FIG. 16.

[0132] FIG. 19 is a schematic diagram showing an aroma cartridge 2-15 using a columnar reinforcing material 2251-4-s4 of a solid concentric cylinder (not hollow) instead of the tubular reinforcing material 2251-3-s4 which was a concentric tube in FIG. 18. Whether to use a hollow circular tube or a solid cylinder can be appropriately exchanged according to the balance between the reinforcing effect and the suction amount.

[0133] The reinforcing support members in FIGS. 16 to 19 can constitute a mouthpiece together with the filter in which the cavities described in FIGS. 5 to 10 are formed, and further, a cooling member can also be connected to constitute a mouthpiece.

[0134] FIG. 20 is a schematic diagram showing the aromatic cartridge 2-15, which shows an example of an aromatic cartridge in which a mouthpiece connecting the reinforcing support members of FIGS. 16 to 19 and the filter with cavities described in FIGS. 5 to 10 is joined adjacent to the heated aromatic body. This includes a reinforcing support member 2251-5 provided with shape reinforcing materials 2251-3-s3 and 2251-3-s4 for preventing the movement of the adjacent heated aromatic generator 21 in the direction of the mouthpiece 225-5, and a filter 2252-5 having one cavity for filtering gas adjacent thereto. The mouthpiece 225-5 is adjacent to the heated aromatic body 21, and these are joined and wound by 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 in the longitudinal direction on the side of the heated aromatic generator 21 such that the central axes of the straight circular cylinders of the filter 2252-5 and the cavity 2252-5-c1 are substantially the same. The suction optimization means here is a hollow concentric tube-shaped reinforcing material 2251-5-s4 having a radius smaller than the radius of the through-hole 2251-5-h of the support member 2251-5 formed so that the central axis of the support member 2251-5 and the straight circular cylinder are substantially the same, and four plate-shaped reinforcing materials 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 reinforcing material 2251-5-s4 on the outer peripheral side of the tubular reinforcing material 2251-5-s4. It is a shape reinforcing material and is fixedly or movably disposed 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 having various cavities.

[0136] FIG. 21 is a schematic diagram showing the aromatic cartridge 2-15, and shows an example of an aromatic cartridge in which a mouthpiece with a cooling member interposed between the reinforcing support members of FIGS. 16 to 19 and the filter with the cavities described in FIGS. 5 to 10 is connected to the heated aromatic body. A reinforcing support member 2261 having shape reinforcing members 2261-s3 and 2261-s4 for preventing the movement of the adjacent heated aromatic generating body 21 in the direction of the mouthpiece 226, a cooling member 2262 for cooling the gas from the heated aromatic generating body 21, and a filter 2263 in which one cavity 2263-c1 for filtering the gas is formed adjacent to the cooling member 2262 are provided. The mouthpiece 226 is adjacent to the heated aromatic body 21, and these are joined and wound by the cartridge exterior body 23.

[0137] The cavity 2263-c1 is disposed at the end of the filter 2263 on the side of the heated aromatic generating body 21 in the longitudinal direction of the filter 2263 so that the central axes of the straight cylinders of the filter 2263 and the cavity 2263-c1 are substantially the same. The suction optimization means here is a hollow concentric tube-shaped reinforcing member 2261-s4 having a radius smaller than the radius of the through hole 2261-h of the support member 2261 formed so that the central axis of the support member 2261 and the straight cylinder are substantially the same, and four plate-shaped reinforcing members 2261-s3 formed so as to contact the inner wall of the through hole 2261-h in the radial direction of the tubular reinforcing member 2261-s4 on the outer peripheral side of the tubular reinforcing member 2261-s4. It is a shape reinforcing member having, and is fixedly or movably disposed as the reinforcing support member 2261. Also in this case, the configuration is not limited to this, and it is possible to combine various reinforcing support members and a filter in which various cavities are formed with a cooling member interposed therebetween.

[0138] As described above, as the suction amount increases due to the improvement of the filter and the support member, the heat of the gas easily convects from the heating element to the filter, so the bonding force between the members constituting the aromatic cartridge decreases, and gas may leak between the members and affect the suction amount. Hereinafter, an aromatic cartridge provided with a heat insulating member between the heated aromatic generating body and the mouthpiece, which can solve this problem, will be provided.

[0139] Figure 22 is a schematic diagram showing an aromatic cartridge 2-18 according to an embodiment of the present invention. The suction optimization means here has a heat insulating member 2271. A mouthpiece 227 including a heat insulating member 2271 adjacent to the heated aromatic generator 21 and a filter 2272 adjacent to the heat insulating member 2271 for filtering gas is adjacent to the heated aromatic generator 21, and these are joined and wound by a cartridge exterior body 23.

[0140] Further, Figure 23 is a schematic diagram showing an aromatic cartridge 2-19 according to an 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 aromatic generator 21, a cylindrical cooling member 2282 adjacent to the heat insulating member 2281 for cooling the gas from the heated aromatic generator 21, and a filter 2283 adjacent to the cooling member 2282 for filtering gas is adjacent to the heated aromatic generator 21, and these are joined and wound by a cartridge exterior body 23.

[0141] These heat insulating members, like the support member adjacent to the heated aromatic body, do not allow the high-temperature gas to spread throughout, but preferably a heat-insulating porous body made of plastic such as a sponge with long continuous holes in the flow path, and have a function of somewhat retaining and cooling, and do not require a cooling function up to the cooling member, and are preferably applied instead of the support member that prevents the movement of the heated aromatic generator in the mouthpiece direction. Therefore, the length s of the heat insulating member depends on the material used, but about 1 to 5 mm is sufficient.

[0142] Next, the lid material and partition material that function as suction optimization means for preventing an extreme decrease in the suction amount caused by clogging of the gaps of the filter and the cooling member by debris and dust such as non-tobacco materials will be described with reference to the drawings.

[0143] FIG. 24 is a partial schematic diagram of a heated aromatic generating body of an aromatic cartridge according to an embodiment of the present invention. The suction optimization means here includes a lid member 211 disposed on the end side of the aromatic cartridge among both ends of the heated aromatic generating body, and a partition member 212 disposed on the other end side of the heated aromatic generating body. As these lid member 211 and partition member 212, a material like a filter that does not reduce the suction amount of gas, a material obtained by slicing an extremely thin slice, a non-woven fabric, and a material like a mesh are preferably used, and they may be fixed to the heated aromatic generating body 21 with an adhesive or the like.

[0144] Such a lid member and partition member may be provided with only one of them or both, depending on the state of the heated aromatic generating base material and the heated aromatic generating body bundling them. By this lid member and / or partition member, clogging of the filter and / or the cooling member due to dropped objects and dust is prevented, and a stable suction amount is ensured. In addition, generation of dropped objects, dust, etc. that occur when the aromatic cartridge is pierced into the needle-shaped heating element can also be prevented.

[0145] As described above, in order to ensure the suction amount of gas when smoking the aromatic cartridge, the physical solution means for structurally improving has been specifically described with reference to the drawings. Hereinafter, a gas generation sustaining material provided in the heated aromatic generating body for solving the reduction in the suction amount of gas will be described with reference to the drawings. The conventional heated aromatic generating body has a problem that the amount of gas released decreases over time, resulting in a decrease in the suction amount of gas during smoking. The aromatic cartridge of the present invention includes a heated aromatic generating base material constituting the heated aromatic generating body, which is provided with a chemical solution means as a gas generation sustaining material for preventing a decrease in the suction amount of gas.

[0146] First, FIG. 25 shows a schematic diagram (A) of a heated aromatic generating sheet constituting a heated aromatic generating body according to an embodiment of the present invention and a schematic diagram (B) of a heated aromatic generating filler constituting a heated aromatic generating body according to an embodiment of the present invention.

[0147] The heated aroma generating substrate is manufactured by various manufacturing processes [means], but finally it is wound as a sheet or a filler to become a heated aroma generating substrate. As shown in FIGS. 2 and 3, the length direction of the heat-not-burn smoking device (1) 11 and (2) 12 corresponds to the length z direction, and it is cut to a length z corresponding to the heat-not-burn smoking device, and 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 body described in FIG. 5. The longitudinal direction of the aroma cartridge corresponds to the length z direction, and the heated aroma generating substrate is wound around paper in this direction to become a heated aroma generating body. The heated aroma generating sheet (A) contained in the heated aroma generating body preferably has a length z of 12 mm for the heat-not-burn smoking device, and the width w and thickness y are in the ranges of 60 to 90 mm and 0.1 to 1.0 mm, respectively. The heated aroma generating filler (B) has a length z of 12 mm, and the width x and thickness y are preferably 1.0 to 2.0 mm and 0.1 to 1.0 mm, respectively. The heated aroma generating filler is obtained by further cutting the heated aroma generating sheet.

[0148] The heated aroma generating body in which one heated aroma generating sheet of FIG. 25(A) is folded and wound with the heated aroma generating body interior material 21-p is shown in FIG. 26(A-1), and the heated aroma generating body in which one heated aroma generating sheet of FIG. 25(A) is wound and wound with the heated aroma generating body interior material 21-p is shown in FIG. 26(A-2). Also, the heated aroma generating body in which 50 heated aroma generating fillers are wound with the heated aroma generating body interior material 21-p is shown in FIG. 26(B). These outer diameters are also appropriately set according to the heat-not-burn smoking device (1) 11 and (2) 12 but correspond to the heated aroma generating body described in FIG. 5. When the outer diameter is 6.9 mm, the filling rate falls within 60 to 90%. In particular, when the filling rate is 60 to 73%, no intense time-dependent fusion has been observed in the heated aroma generating substrate. This filling rate is adjusted by the width w of the heated aroma generating sheet and the number of the heated aroma generating fillers, and this is not the case when a gas generation sustaining material is present.

[0149] Hereinafter, a gas generation sustaining material having a function of preventing a decrease in the gas emission amount of a heat-generating aroma generator, which is closely related to a decrease in the gas suction amount during smoking, and ensuring the gas suction amount, that is, a heat-generating aroma-generating base material to which a chemical solution means is applied, will be specifically described with reference to the drawings. The aroma cartridge of the present invention includes, as a gas generation sustaining material, a heat-generating aroma-generating base material to which this chemical solution means is applied, in a heat-generating aroma generator.

[0150] There are various methods [devices] for the conventional method [device] for manufacturing a heat-generating aroma-generating base material, and an example is shown in FIG. 33. After drying and pulverizing a non-tobacco material, a step [means] of dry-mixing to prepare the non-tobacco material, a step [means] of preparing a material selected from an aerosol former, a binder, an anti-adhesion agent, a fragrance, a non-tobacco material extract, an antibacterial preservative, etc., a step [means] of preparing pure water and alcohol, a wet mixing step [means] of mixing these prepared materials together, a papermaking step [means] of producing a water-containing sheet from the slurry produced by wet mixing, a forming step [means] of compressing or casting the paper-made water-containing sheet to produce a sheet, a step [means] of drying the sheet produced in the forming step [means], and a sheet processing step [means] of cutting or bending the dried heat-generating aroma-generating sheet.

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

[0152] (Production Example 1) The following pulverized materials were put into a dry mixer as non-tobacco materials and dry-mixed for 5 minutes. 100 parts by mass of dried and pulverized black tea leaves 20 parts by mass of dried and pulverized licorice root of the legume family 10 parts by mass of dried and pulverized lotus leaves

[0153] The above dry mixture and the following materials were put into a wet mixer and wet-mixed for 15 minutes. 25 parts by mass of polypropylene glycol 25 parts by mass of glycerin 5 parts by mass of sodium carboxymethyl cellulose 3 parts by mass of menthol 3 parts by mass of ethanol 200 parts by mass of pure water

[0154] In the step [means] of forming a sheet from the slurry thus obtained, a specified amount of the above slurry was put into a frame equipped with an appropriate sieve to create a water-containing sheet. At this time, in this production example, the water content of the above slurry was approximately 95 when the water content of the water-containing sheet was set to 100.

[0155] Subsequently, the above water-containing sheet was passed through a press roll with a predetermined clearance three times for forming. Then, 7 parts by mass equivalent of pure water was added to 100 parts by mass of the water-containing sheet that had been passed through three times, and the sheet was further passed through the press roll five times.

[0156] Furthermore, the formed water-containing sheet obtained as described above was dried in an environment at 35°C for 300 minutes to produce a heated aromatic generating sheet with a water content of 20% by mass. Regarding the drying temperature, it is preferably less than 50°C in order to maintain the fragrance. More preferably, it is less than 45°C, and even more preferably, it is less than 40°C. The thickness of the sheet is adjusted as appropriate, but in this production example, the thickness was set to 0.5 mm. This sheet was cut into a rectangular heated aromatic generating sheet with a length of 240 mm × width of 75 mm and a heated aromatic generating filler with a length of 240 mm × width of 1.5 mm. The length direction of the sheet and the filler obtained by cutting the heated aromatic generating sheet is parallel to the rotation axis of the roll, and the width direction is the rotation direction of the roll.

[0157] One heated aromatic generating sheet and 50 heated aromatic generating fillers produced in this way were each wound and then cut so that the length became 12 mm, and heated aromatic generating bodies as shown in FIGS. 26(A-1) and 26(B) were produced. Then, an aromatic cartridge of the type in which the heated aromatic generating body is joined to a mouthpiece equipped with a support member and a filter shown in FIG. 13 was produced. As the support member, a PE tube with an outer diameter of 6.9 mm and a through-hole with an inner diameter of 4.0 mm provided in a cylindrical shape was used. The filter was formed by molding acetyl cellulose fibers into a cylindrical shape, and the basis weight was 34 g / m2 A 23-mm-long one wrapped with paper was used. The cartridge outer body was formed by using paper with a basis weight of 38 g / m² 2 and winding it two and a half times so that the inner diameter became 6.9 mm and then pasting it. Note that as the cartridge outer body, a paper tube formed by winding paper with a basis weight of 32 to 45 g / m² 2 two and a half times is used, it becomes suitable as an aromatic cartridge that is used by inserting the portion of the heat-generating aromatic body into the heating element of the heat-not-burn smoking device. Then, after inserting the support member and the filter from one end of the cartridge outer body to form a mouthpiece, and inserting the heat-generating aromatic body from the other end, paper with a basis weight of 40 g / m² 2 was wound so as to overlap the mouthpiece portion to produce an aromatic cartridge. However, as the filter, a filter in which no cavity, which is a suction optimization means, is formed was used in order to clarify the influence of the manufacturing method [apparatus] on the heat-generating aromatic base material, that is, the difference in the function of the gas generation sustaining material.

[0158] The heat-generating aromatic body and the aromatic cartridge thus produced were evaluated as follows.

[0159] ≪Evaluation 1≫ The prepared aromatic cartridge was filled in a paper box with a long side of 70 mm, a short side of 14 mm, and a height of 45 mm so that the heat-generating aromatic body faced the bottom. In this way, the box containing the prepared aromatic cartridge was placed in a plastic bag and left in an environment of 40°C for two weeks. Then, it was taken out and the following evaluation was performed on the one left in a normal temperature and normal humidity environment for one day. The filling was taken out from the heat-generating aromatic body and it was confirmed whether they were solidified. At the same time, five subjects were asked to smoke, and a sensory evaluation of the suction amount and flavor was carried out. Rank A: Those that loosen when taken out with tweezers Those in which four or more people can sufficiently feel both the suction amount and the flavor Rank B: Those that loosen when pressed with tweezers Those in which two or more people can sufficiently feel both the suction amount and the flavor Rank C: Those that remain in a lump even when pressed with tweezers Those that cannot be fully perceived in terms of both the amount of suction and flavor Those in Rank C are likely to become difficult to insert into the heating element of the heat-not-burn smoking device due to long-term storage or the like.

[0160] The aromatic cartridge produced in (Production Example 1) was rated as Rank C. The heatable aromatic generating sheet and the heatable aromatic filler were fused over time, resulting in a decrease in the amount of gas released during smoking, i.e., the amount of gas suction, and a change in flavor, and it did not function as a gas generation sustaining material for the heatable aromatic.

[0161] This problem was solved by improving the manufacturing method [apparatus]. This manufacturing method [apparatus] is characterized in that, as shown in Fig. 27, a second wet mixing process [means] is introduced as a manufacturing process [means]. As is clear from the figure, a dry mixing process [means] Z1 for mixing the dried and pulverized non-tobacco material, the non-tobacco material produced in the dry mixing process [means], and a material selected from an aerosol former, a binder or thickener, crosslinked PVP, a fragrance, a non-tobacco extract, β-cyclodextrin, microcrystalline cellulose, and an antibacterial preservative are mixed in an alcohol and pure water mixture in a first wet mixing process [means] M2, pure water and / or alcohol is further added to the alcohol and pure water mixture containing the non-tobacco material etc. produced in the first wet mixing process [means] to produce a slurry containing the non-tobacco material etc. in a second wet mixing process [means] M3, a papermaking process [means] S1 for producing a water-containing sheet from the slurry produced in the second wet mixing process [means], a sheet forming process [means] S2 for compressing the water-containing sheet into a sheet, and a drying process [means] S3 for drying the sheet produced in the sheet forming process [means] to produce a heatable aromatic generating sheet, and the heatable aromatic generating base material is produced from a sheet processing process [means] H1 for cutting or bending the heatable aromatic generating sheet.

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

[0163] (Production Example 2) After drying black tea leaves at 70°C until the moisture content reaches 2% by mass, they are pulverized. Similarly, leguminous licorice, lotus leaves, and Korean ginseng are dried and pulverized. 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. When it is 65°C or higher, it is even easier to reach the desired moisture content, and when it is 75°C or lower, it is possible to further prevent the dissipation of the required aroma components.

[0164] Note that the moisture content after pulverization is preferably 5% by mass or less. By doing so, slurrying in the subsequent process [means] becomes easy. It is more preferably 3% by mass or less. Also, when the moisture content is 0.1% by mass or more, it is preferable because it can maintain a good affinity with water and the like.

[0165] In this way, the dried and pulverized material that has passed through an 80-mesh sieve is used as a non-tobacco material, put into a dry mixer in the following blending amounts, and dry mixed for 5 minutes. Dried and pulverized black tea leaves 100 parts by mass Dried and pulverized leguminous licorice 20 parts by mass Dried and pulverized lotus leaves 10 parts by mass Dried and pulverized Korean ginseng 5 parts by mass

[0166] The above dry mixture and the following materials are put into a wet mixer, and the first wet mixing is carried out for 15 minutes. Polypropylene glycol 30 parts by mass Glycerin 20 parts by mass Sodium carboxymethyl cellulose 5 parts by mass Menthol 3 parts by mass Ethanol 3 parts by mass 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 above slurry and charged, and the second wet mixing is carried out for 10 minutes. Here, ethanol is added because the dispersion state of the above dry pulverized product with respect to polypropylene glycol and glycerin can be greatly improved. The alcohol is not limited to ethanol as long as it is a lower monoalcohol. The addition amount of such a lower monoalcohol is preferably 0.1 to 10 parts by mass with respect to 100 parts by mass of the dry pulverized product. When it is 0.1 part by mass or more, improvement in the above dispersion state is recognized, and when it is 10 parts by mass or less, residual of the lower monoalcohol can be suppressed. If it is 0.5 to 5 parts by mass, this effect is more remarkable.

[0168] The reason for initially charging pure water to form a mixture is that the dispersion of the above mixture can be advanced in advance, and then a slurry with good dispersibility can be obtained by diluting and mixing with additional water. It is also preferable to charge water in multiple portions. When charging in multiple portions, it is preferable to take a combination of reducing the amount of water charged previously and increasing the amount of water charged later. By doing so, the degree of improvement in dispersibility when water is charged previously is high, and when the amount of water charged later is increased, a uniform slurry is obtained.

[0169] In the step [means] of forming a sheet from the slurry obtained as described above, a specified amount of the above slurry was charged into a frame equipped with a suitable sieve to create a water-containing sheet. At this time, in this example, the water content of the water-containing sheet is approximately 95 when the water content of the above slurry is 100.

[0170] Subsequently, the above water-containing sheet was passed through a press roll with a predetermined clearance three times for forming. Thereafter, with respect to 100 parts by mass of the water-containing sheet that had been passed through three times, 7 parts by mass equivalent of water was added to the water-containing sheet, and then the sheet was passed through the press roll five more times. Preferably, it is 2 parts by mass or more and 15 parts by mass or less of water with respect to 100 parts by mass of the water-containing sheet. In this way, when forming the water-containing sheet multiple times, adding water in the middle has the effect of easily making the water contained in the water-containing sheet uniform within a certain range, and has the effect of making the conditions of the subsequent drying process [means] uniform, and also has the effect of making the quality of the final product uniform.

[0171] Furthermore, the formed water-containing sheet obtained as described above was dried in an environment at 35°C for 300 minutes to create a formed sheet for an electronic cigarette filler with a water content of 20% by mass. Regarding the drying temperature, it 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 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 filler with a length z of 240 mm and a width x of 1.5 mm so as to be wound 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 so that the length z became 12 mm, and a heated aroma-generating body as shown in FIGS. 26(A-1) and 26(B) was produced. And, (Manufacturing Example 1) Similarly, an aroma cartridge of the type that joins the heated aroma-generating body to a mouthpiece provided with a support member and a filter as shown in FIG. 13 was produced. However, as a filter, a filter in which a cavity, which is a suction optimization means, is not formed was used in order to clarify the influence of the manufacturing method [apparatus] on the heated aroma-generating base material, that is, the difference in the function of the gas generation sustaining material.

[0173] Then, similar to the aromatic cartridge produced in (Production Example 1), when <<Evaluation 1>> was conducted, a result of Rank A was obtained. This indicates that the heated aromatic generating substrate produced by this method [apparatus] has little temporal fusion inside and between the heated aromatic generating substrates that occurs over time, little change in the amount of gas released by heating, and is considered to maintain the gas suction amount during smoking. That is, the heated aromatic generating substrate produced by this method [apparatus] functions as a gas generation sustaining material for the heated aromatic generating substrate.

[0174] The manufacturing method [apparatus] shown in Fig. 27 was improved as shown in Fig. 28. The manufacturing method [apparatus] in Fig. 28 is characterized in that, in the sheet forming step [means] S2 in the manufacturing method [apparatus] shown in Fig. 27, a step [means] S3 of adding an aerosol former is further added when the water content of the sheet becomes less than 50%. Specifically, the blending amount of propylene glycol in the first wet mixing in (Production Example 2) was reduced by 10 parts by mass, a 50% ethanol solution of propylene glycol was used, and it was sprayed at a temperature of less than 40 °C to absorb propylene glycol into the sheet, compensating for the propylene glycol reduced in the first wet mixing. Here, it is preferable to carry out the concentration of the alcohol solution of the aerosol former in the range of 20 to 80% from the viewpoints of the absorbability of the aerosol former and the drying property of alcohol. If the concentration is high, it is difficult to be absorbed, and if the concentration is low, it takes time for the alcohol to dry. The absorption temperature is also preferably 20 to 50 °C from the viewpoint of the absorbability of the aerosol former. If the temperature is too high, the evaporation of the aerosol former is intense, and if the temperature is too low, it becomes 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 promptly carried out. The heated aromatic generating substrate with a thickness of 0.5 mm produced by this method [apparatus] was also cut into the same size as in (Production Example 2), an aromatic cartridge was produced, and when <<Evaluation 1>> was conducted, a result of Rank A was obtained, and it became clear that the heated aromatic generating sheet produced by this method [apparatus] also functions as a gas generation sustaining material for the heated aromatic generating substrate.

[0176] The common improvement of the manufacturing methods [devices] of FIGS. 27 and 28 lies in the improvement of the mixing and dispersion of the non-tobacco material and the aerosol former. In view of this point, the manufacturing method [device] that does not go through the mixing and dispersion process [means] of the non-tobacco material and the aerosol former is the manufacturing process [means] of the heated aroma-generating base material shown in FIG. 29.

[0177] That is, a wet mixing process [means] M1 for mixing the dried and pulverized non-tobacco material for producing the gas generation sustaining material with pure water to produce a slurry of the non-tobacco material, a papermaking process [means] S1 for producing a water-containing sheet from the slurry produced in the wet mixing process [means], a sheet forming process [means] for compressing or casting the water-containing sheet into a sheet, and S2, a drying process [means] S3 for reducing the water content of the sheet produced in the sheet forming process [means] to less than 50% by mass, and applying or dipping the sheet produced in the drying process [means] with an alcohol and pure water mixture of a material selected from an aerosol former, a binder or thickener, crosslinked PVP, a fragrance, a non-tobacco extract, β-cyclodextrin, microcrystalline cellulose, a concentrated solution of the water discharged in the sheet forming process [means], and an antibacterial preservative Absorption and adsorption process [means] S4, a drying process [means] S5 for drying the sheet produced in the absorption and adsorption process [means] to produce a heated aroma-generating sheet, and a sheet processing process [means] H1 for cutting or bending the heated aroma-generating sheet. The heated aroma-generating base material is produced from these.

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

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

[0180] This slurry was cast into a sheet with a thickness of 0.5 mm. The remaining water from the casting was concentrated and stored for use in the next process [means].

[0181] Dry the above sheet, and per 100 parts by mass of the sheet, 10 parts by mass of polypropylene glycol 20 parts by mass of glycerin 2 parts by mass of sodium carboxymethyl cellulose 3 parts by mass of menthol (50% ethanol solution) 50 parts by mass of concentrated water of cast-off are added and dried to produce a sheet.

[0182] The produced sheet was used to produce a heat-generating aromatic generator and an aromatic cartridge using the same in the same manner as in (Production Example 2), and when <<Evaluation 1>> was carried out, a result of Rank A was obtained, and it was revealed that the heat-generating aromatic sheet produced by this method [apparatus] also functions as a gas generation sustaining material for the heat-generating aromatic substrate.

[0183] The conventional production method [apparatus] was characterized by producing a slurry of a non-tobacco material or the like and papermaking to produce a heat-generating aromatic sheet. However, as shown in FIG. 29, a method [apparatus] of absorbing an aerosol former, a fragrance, a binder, etc. into a water-containing sheet produced by papermaking a slurry of only a non-tobacco material gave good results. Therefore, it was considered that there was a problem in the process [means] of papermaking from slurries of various materials with different properties, and as a result of studying a production method [apparatus] that does not require a papermaking process [means], the method [apparatus] shown in FIG. 30 was found. It is characterized in that a large shearing force and a compressive force, such as a three-roll, are applied to a mixture of a non-tobacco material or the like.

[0184] That is, a non-tobacco material preparation step [means] Z1 and 2 for drying and pulverizing a non-tobacco material, and a step of dissolving a fragrance and / or a non-tobacco material extract [means] M1 for mixing at least a fragrance and / or a non-tobacco material extract, crosslinked PVP and / or β-cyclodextrin in alcohol to lodge the fragrance and / or the non-tobacco extract in crosslinked PVP and / or β-cyclodextrin, a step of dissolving an aerosol former [means] M2 for mixing at least an aerosol former and a binder or a thickener in pure water, a wet mixing step [means] M3 for mixing the material produced in the non-tobacco material preparation step [means], the material produced in the step of dissolving a fragrance and / or a non-tobacco extract [means], and the material produced in the step of dissolving an aerosol former [means], a sheet forming step [means] S1 for compressing the material produced in the wet mixing step [means] to produce a heatable fragrance generating sheet, and a sheet processing step [means] H1 for cutting or bending the heatable fragrance generating sheet, which is a method [apparatus] for producing a heatable fragrance generating substrate.

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

[0186] (Production Example 4) In the non-tobacco material preparation step [means] Z1 and 2 for drying and pulverizing a non-tobacco material, tea leaves are used as the non-tobacco material, dried in an oven at 70 °C, then pulverized using a stirring type pulverizer, passed through an 80 mesh sieve, and a non-tobacco material with a moisture content of 2% by mass is prepared.

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

[0188] Here, menthol is not limited to that obtained from natural products, and synthetic products can also be used. Further, mint, mint, peppermint oil, and other materials containing menthol may be used.

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

[0190] The water-insoluble crosslinked polymer is intended to be a polymer obtained by crosslinking a non-crosslinked polymer that is soluble in water to make it insoluble in water and swell. Of course, it is preferably insoluble in the lower alcohol and swells, and such a polymer is selected. Such a water-insoluble crosslinked polymer has a hydrophilic part and a hydrophobic part, and it is considered that the hydrophilic part contributes to swelling, and the dissipation of menthol is suppressed when the hydrophilic part is oriented to menthol. Preferred examples of the hydrophilic crosslinked polymer include crosslinked PVP and crosslinked polysaccharides obtained by subjecting water-soluble polysaccharides to epoxy crosslinking, ester crosslinking, or ether crosslinking to make them water-insoluble. In particular, when ethanol and crosslinked PVP are used together with menthol, the effect of significantly suppressing the dissipation of menthol was recognized.

[0191] For menthol, it is sufficient to add an amount targeted for the desired flavor, but the menthol content in the heat-generating aromatic substrate is preferably 0.1 to 10% by mass, more preferably 0.2 to 5% by mass.

[0192] In forming the heat-generating aromatic substrate, the addition amount of the hydrophilic crosslinked polymer is preferably 10 to 2000 parts by mass, 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, in the heated aroma-generating substrate, the hydrophilic crosslinked polymer preferably exists in an amount of 2% by mass or more, more preferably 4% by mass or more. By having such an amount, long-term storage becomes possible while suppressing the dissipation of menthol, and the refreshing feeling of menthol can be enjoyed even after long-term storage. Further, in the heated aroma-generating substrate, the content of the hydrophilic crosslinked polymer is preferably 20% by mass or less, more preferably 10% by mass or less. When it is 10% by mass or less, it is possible to maintain the flavor caused by non-plant-derived polyphenols and the like.

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

[0195] From the above, as an example, 100 parts by mass of menthol 200 parts by mass of ethyl alcohol 200 parts by mass of polyvinyl polypyrrolidone Weigh them, dissolve menthol in ethyl alcohol to obtain a menthol ethyl alcohol solution, then add crosslinked PVP to the menthol ethyl alcohol solution, stir and mix to obtain a menthol / ethyl alcohol / crosslinked PVP mixture.

[0196] Next, in the process [means] M2 of dissolving materials such as aerosol formers, the aerosol former, flavor additive, preservative, binder or thickener, 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 dodecanedioate, dimethyl tetradecanedioate, 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 heatable aromatic generating substrate.

[0198] The flavoring agent for adding flavor is used as needed, and examples include extracts such as mint, cocoa, coffee, and black tea.

[0199] Also, an antibacterial preservative for food can be added as needed. As the antibacterial preservative, sorbic acid, potassium sorbate, benzoic acid, sodium benzoate, etc. can be used.

[0200] As the binder or thickener, etc., 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, organic acids such as starch and alginic acid, and polysaccharides such as conjugate base salts of organic acids such as sodium alginate, sodium carboxymethyl cellulose, carrageenan, agar, and pectin can be used. These may be used in combination.

[0201] From these, 20% aqueous solutions of glycerin, propylene glycol, sodium carboxymethyl cellulose, methyl cellulose, glucomannan, and xylitol were prepared.

[0202] Next, in the step [means] M3 of wet-mixing the materials of each of the steps [means] Z1 and 2 of the non-tobacco material preparation step, the step [means] M1 of the flavor dissolution step, and the step [means] M2 of the aerosol former dissolution step, a normal wet mixer was used, and with the following formulation, while applying a shearing force with a stirring blade for 15 minutes, stirring was carried out to produce a composition for a heat-generating aroma-generating substrate of a non-tobacco plant. 100 parts by mass of dried and pulverized black tea leaves 25 parts by mass of menthol / ethyl alcohol / crosslinked PVP 30 parts by mass of glycerin 30 parts by mass of propylene glycol 4 parts by mass of sodium carboxymethyl cellulose 15 parts by mass of methyl cellulose 8 parts by mass of xylitol aqueous solution 1 part by mass of glucomannan

[0203] In the step [means] S1 of forming a sheet, a three-roll mill was used. The above composition was put into a three-roll mill, 20 parts by mass of pure water was added while observing the state of the sheet, and the step [means] of pressing a doctor blade against the roll to collect a sheet-like material was repeated 8 times to obtain a final sheet-like non-tobacco plant composition. When using a three-roll mill, due to the compressive force caused by being pushed into the narrow space between the rolls and the shearing force caused by the roll speed difference, kneading, dispersion, etc. can be carried out, and a sheet with a desired thickness can be obtained by a doctor blade, and a sheet can be manufactured more homogeneously than by producing a sheet from the papermaking step [means] of a slurry. In addition to a three-roll mill, a press roller or a press machine can also be preferably used.

[0204] In the step [means] S1 of sheet forming, if necessary, a non-tobacco plant, an aerosol former, a flavor, an antibacterial preservative, a binder or thickener, water, etc. may be added.

[0205] Note that the pure water used in the present invention is preferably sterilized or free of microorganisms, but pure water obtained by reverse osmosis membrane or ion exchange, etc. may also be used.

[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 steps [means] Z1 and 2 of preparing dried and pulverized non-tobacco materials, the step [means] M1 of preparing a first binder aqueous solution by dissolving a first binder in pure water, the steps [means] Z4 and 5 of preparing materials selected from an aerosol former, crosslinked PVP, a fragrance, a non-tobacco material extract, β-cyclodextrin, microcrystalline cellulose, and an antibacterial preservative, and the first wet mixing step [means] M1 of mixing the materials prepared in the above steps, the curing step [means] Y1 of stabilizing the mixed solution produced in the first wet mixing step [means], the second wet mixing step [means] M2 of mixing the cured mixed solution produced in the curing step [means] and a second binder aqueous solution prepared in the step [means] Z6 of dissolving a second binder in pure water, the sheet forming step [means] S1 of compressing the materials produced in the second wet mixing step [means] to produce a heatable aroma generating sheet, and the sheet processing step [means] H1 of cutting or bending the heatable aroma generating sheet. The heatable aroma generating substrate produced therefrom can stably maintain a lump state and does not block the gas flow path. Also, no fusion was observed between the heatable aroma generating substrates over time.

[0211] As a specific example of this manufacturing method [apparatus], (Manufacturing Example 5) is shown.

[0212] (Manufacturing Example 5) In the step [means] Z1 of drying and pulverizing the non-tobacco plant as a raw material, it is preferable to adjust the moisture content so as to easily absorb or carry an aerosol former, pure water, and other components. The drying temperature is preferably 60 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. When it is 65°C or higher, it is easier to reach the desired moisture content, and when it is 75°C or lower, the dissipation of the required aroma components can be further prevented. The moisture content after drying and pulverizing is preferably 5% by mass or less, which facilitates slurrying in the subsequent steps [means]. It is more preferably 3% by mass or less. However, if the moisture content is less than 0.1% by mass, the affinity with water or the like decreases. Further, by providing a sieving step [means] for sieving the dried and pulverized product, non-tobacco plants with a desired particle size can be introduced into the first wet mixing step [means] M3, facilitating slurrying.

[0213] Step of preparing by dissolving the first binder in pure water [Means] As the first binder used in Z3, celluloses, konjac mannan (glucomannan), guar gum, pectin, carrageenan, tamarind seed gum, gum arabic, soybean polysaccharides, locust bean gum, karaya gum, xanthan gum, agar, corn starch, etc. can be mentioned, but celluloses are preferred. Regarding the viscosity, when the solution viscosity is 300 mPa·s or more, the mixing with non-tobacco plants is good. Also, when the solution viscosity is 5000 mPa·s or more, it is suitable for binding non-tobacco plants. The solution viscosity is a measured value obtained by using a Brookfield viscometer, preparing a 1% aqueous solution, starting the rotation of the rotor at 10 to 30 rpm in an environment of 25°C, and measuring when the displayed value becomes stable. Here, the upper limit of the measurement of 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, those that are water-soluble are particularly preferred from the viewpoint of binding non-tobacco plants. 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] Step [Means] of preparing an aerosol former: As the aerosol former used in Z4, glycerin, propylene glycol, sorbitol, triethylene glycol, lactic acid, diacetin (glycerin diacetate), triacetin (glycerin triacetate), triethylene glycol diacetate, triethyl citrate, isopropyl myristate, methyl stearate, dimethyl dodecanedioate, dimethyl tetradecanedioate, etc. can be used. In particular, glycerin and propylene glycol are preferred. These are used in the range of 1 to 80% by mass with respect to the composition of the heated aromatic generating substrate, and particularly preferably 10 to 40% by mass.

[0216] Step [Means] of preparing materials to be used other than the above: In Z5, flavoring agents such as menthol, peppermint, cocoa, coffee, and tea extracts, crosslinked PVP and β-cyclodextrin having the function of retaining flavoring agents, microcrystalline cellulose having releasability and moldability with respect to molds, etc., and food antibacterial preservatives such as sorbic acid, potassium sorbate, benzoic acid, and sodium benzoate for storage stability can be added as necessary to add flavor.

[0217] The materials prepared as above are mixed in the first wet mixing step [Means] M1. The mixer does not require anything special. For example, a mixer that mixes the materials in the mixing tank while applying shear force with stirring blades may be used, and it is also possible to knead using a roll mill, kneader, or extruder to further enhance the mixing. The mixing temperature in this step [Means] is preferably 40°C or lower, more preferably 30°C or lower, 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, temperature control of the mixing tank is necessary.

[0218] The first mixture produced in the first wet mixing step [means] M1 preferably undergoes a curing step [means] Y1 of being left at a predetermined temperature and for a predetermined time, but this is not an essential step [means]. However, the binder must necessarily be added separately to the first mixing step [means] and the second mixing step [means]. In this way, whether it is a non-tobacco material mixture that does not undergo the curing step [means] Y1 with the binder added separately or a cured mixture that has undergone the curing step [means] Y1, when the heat-generating aroma-generating substrate is processed into an aroma cartridge and smoked and evaluated using, for example, the smoking device shown in FIG. 2, both the initial draw amount and the flavor are improved. Even when evaluating the storage stability in a high-temperature and high-humidity environment, there is no fusion between the inside of the heat-generating aroma-generating substrate and between the heat-generating aroma-generating substrates, and there is no change over time in the amount of aerosol smoke and the release amount of the aroma components of the non-tobacco material during the initial smoking, that is, the draw amount, and no change in the flavor is observed. In particular, when using tea as the non-tobacco material, the effect is remarkable and preferable. However, the curing step [means] Y1 can enhance these effects even more.

[0219] The temperature of the curing step [means] Y1 is preferably 15 to 30°C, more preferably 18 to 24°C. When it is 15°C or higher, the above-described flavor improvement effect is enhanced. When it is 30°C or lower, the change in the draw amount and the change in the flavor over time are suppressed, and the improvement in the flavor over time is maintained. In the case of 18 to 24°C, these effects are more remarkable. Also, the time of the curing step [means] Y1 is preferably 72 to 336 hours, more preferably 96 to 192 hours. When it is 72 hours or more, an improvement in the flavor is observed. When it is 336 hours or less, the change in the draw amount and the change in the flavor over time are suppressed, and the improvement in the flavor over time is maintained. In the case of 96 to 192 hours, these effects are more remarkable. And the curing is preferably carried out with the mixture after the first wet mixing under sealing. This is to prevent the dissipation of the aroma.

[0220] The mixture immediately after the first wet mixing and the mixture cured after the first wet process [means] are fed into the second wet mixing process [means] M2. The second wet mixing process [means] M2 is characterized by adding a second binder and performing mixing. In this way, the effect of the divided addition of the first binder and the second binder, in addition to the effects of improving the initial suction amount and flavor and reducing the temporal changes in the suction amount and flavor, makes it easier to form into a desired shape in the sheet forming process [means] H1. Also, compared to adding in the first process [means], mixing becomes easier, the time until the viscosity of the mixture becomes uniform can be shortened, and viscosity adjustment becomes easier.

[0221] As the second binder, similar to the first binder, celluloses, konjac mannan (glucomannan), guar gum, pectin, carrageenan, tamarind seed gum, gum arabic, soy polysaccharides, locust bean gum, karaya gum, xanthan gum, agar, starch, corn starch, etc. can be used, but polysaccharides other than celluloses are preferred. Regarding the viscosity, similar to the first binder, when the solution viscosity is 300 mPa·s or more, the mixing with non-tobacco plants is good. Also, when the solution viscosity is 5000 mPa·s or more, it is suitable for binding non-tobacco plants. Note that this viscosity is also measured by the method [apparatus] described above. Here, the upper measurement limit of the Brookfield type viscometer is 100,000 mPa·s, but viscosities exceeding this upper limit also fall within the viscosity range described above.

[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 heat-generating aromatic substrate containing the non-tobacco material produced by the second wet mixing M2 is fed into the sheet forming step [means] H1 and formed into a desired shape. To use this composition as a heat-generating aromatic substrate, sheet forming processes such as roll forming and press forming are preferred, but not limited thereto. A method [apparatus] of forming into a rod shape by passing through an orifice under pressure, or a method [apparatus] of pulverizing into granules after drying may be employed.

[0226] Here, a sheet forming process suitable for the production of the heat-generating aromatic substrate will be described. As one method [apparatus], it was formed into a sheet using a three-roll mill. When using a three-roll mill, due to the compressive force caused by being pushed into the narrow space between the rolls and the shearing force caused by the speed difference between the rolls, while performing kneading and dispersion, etc., it is possible to form a sheet of a desired thickness with a doctor blade, which is particularly preferable for sheet forming of the composition of the present invention in which a wide variety of materials with different properties are mixed. Also, it may be produced by using a press roller or a press machine in combination. Thus, since the three-roll mill performs kneading and dispersion while processing into a sheet shape, it complements the first and second wet mixings and can achieve a more preferable mixing and dispersion state. Therefore, when using a three-roll mill in the second wet mixing step [means] M2, the second wet mixing step [means] M2 and the sheet forming step [means] H1 have no distinction in terms of equipment, meaning that mixing and forming are being carried out within the same process.

[0227] Thus, in sheet forming using a three-roll mill, since mixing and dispersion can be performed, as needed, a production method [apparatus] may also be adopted in which a non-tobacco material, aerosol former, binder or thickener, flavor, crosslinked PVP, β-cyclodextrin, microcrystalline cellulose, antibacterial preservative, pure water, etc. are also added.

[0228] In order to clarify the features of a method [apparatus] for manufacturing a heatable aroma-generating base material in which such a first binder and a second binder are added separately, the materials used were made common, the form of the heatable aroma-generating base material was limited to a filler, and a comparative evaluation was made with a conventional manufacturing method [apparatus]. The present invention will be described with manufacturing examples and examples.

[0229] (Manufacturing Example A) 100 parts by mass of xylitol 400 parts by mass of water were stirred and mixed to obtain a xylitol / aqueous solution.

[0230] Next, tea leaves were dried at 70 °C, pulverized, and those that passed through an 80-mesh sieve were used. The moisture content was 2% by mass. Similarly, the dried product of ama-cha vine was pulverized and those that passed through an 80-mesh sieve were used.

[0231] 80 parts by mass of the dried and pulverized tea leaves 20 parts by mass of the dried and pulverized ama-cha vine 15 parts by mass of methyl cellulose 30 parts by mass of glycerin 30 parts by mass of propylene glycol 4 parts by mass of sodium carboxymethyl cellulose 8 parts by mass of the xylitol / aqueous solution were put 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 a second wet mixing step [means] M2. While 100 parts by mass of the first mixture was being put into a three-roll mill, 0.5 part by mass of glucomannan and 20 parts by mass of water were added. Thereafter, the step [means] of pressing a doctor blade against the roll to collect a sheet-like material was repeated 8 times. Such a step [means] is performed by the same apparatus for the second wet mixing step [means] M2 and the sheet forming step [means] H1, 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 having a desired thickness was manufactured by the three-roll mill while also performing kneading and dispersion.

[0233] Through these steps [means], the heated aroma generating sheet produced was formed to have a thickness of 0.3 mm. This sheet was cut into a rectangle with a length of 150 mm and a width of 240 mm, supplied to a rotary cutter, and processed into a shape with a width of 1.5 mm, a length of 240 mm, and a thickness of 0.3 mm to obtain a heated aroma generating filler. Fifty of these fillers were bundled and aligned in the longitudinal direction, and then wound and glued with paper having a basis weight of 34 g / m 2 to form a cylindrical processed product for heated aroma generation. The inner diameter of this processed product was 6.9 mm. Further, it was 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 volume filling rate of the filler with respect to its volume was 0.60. Note that the longitudinal direction of the rectangle obtained by cutting the heated aroma generating sheet was parallel to the rotation axis of the roll, and the transverse direction was the rotation direction of the roll (the same applies hereinafter).

[0234] The aqueous solution viscosity of the sodium carboxymethyl cellulose used in this production example was 650 mPa·s (Brookfield viscometer, 1% aqueous solution, 25°C), and the aqueous solution viscosity of glucomannan, which is a polysaccharide, was 44000 mPa·s (Brookfield viscometer, 1% aqueous solution, 25°C).

[0235] (Production 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 became about 1.5 times. When the second cured mixture after the curing step [means] Y1 was examined, it was found that the liberation of the pulverized tea was less than before curing, and it is considered that the curing led to a stable and uniform dispersion 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] (Production Example C) (Production Example B) In the same manner, the curing mixture was charged into the second wet mixing step [means] M2, and a heat-generating aromatic sheet was produced through the sheet forming step [means] H1. However, in this production example, in the second wet mixing step [means] and the sheet forming step [means] H1, the processing conditions were changed, and the sheet was formed to a thickness of 0.1 mm to produce a heat-generating aromatic sheet. This sheet was cut into a rectangle with a length of 150 mm and a width of 240 mm and supplied to a rotary cutter to obtain a heat-generating aromatic filler processed into a shape with a width of 1.0 mm, a length of 240 mm, and a thickness of 0.1 mm. 225 of these fillers were bundled and aligned in the longitudinal direction, and then wrapped with paper having a basis weight of 34 g / m 2 and glued to form a cylindrical heat-generating aromatic processed product. The inner diameter of this processed product was 6.9 mm. Further, it was cut into a length of 12.0 mm to obtain a heat-generating aromatic body. The mass of this heat-generating aromatic body was 0.29 g, and the volume filling ratio of the filler to its volume was 0.60.

[0237] (Production Example D) (Production Example B) In the same manner, the curing mixture was charged into the second wet mixing step [means] M2, and a heat-generating aromatic sheet was produced through the sheet forming step [means] H1. However, in this production example, in the second wet mixing step [means] and the sheet forming step [means] H1, the processing conditions were changed, and the sheet was formed to a thickness of 0.5 mm to produce a heat-generating aromatic sheet. The heat-generating aromatic sheet was cut into a rectangle with a length of 150 mm and a width of 240 mm and supplied to a rotary cutter to obtain a heat-generating aromatic filler processed into a shape with a width of 1.0 mm, a length of 240 mm, and a thickness of 0.5 mm. 225 of these fillers were bundled and aligned in the longitudinal direction, and then wrapped with paper having a basis weight of 34 g / m 2 and glued to form a cylindrical heat-generating aromatic processed product. The inner diameter of this processed product was 6.9 mm. Further, it was cut into a length of 12.0 mm to obtain a heat-generating aromatic body. The mass of this heat-generating aromatic body was 0.29 g, and the volume filling ratio of the filler to its volume was 0.60.

[0238] For comparison, methylcellulose and carboxymethylcellulose, which are the first binders, and glucomannan, which is the second binder, were added all at once to produce a heat-generating aromatic material.

[0239] (Comparative production example) 100 parts by mass of xylitol 400 parts by mass of water were stirred and mixed to obtain an xylitol / aqueous solution.

[0240] Next, tea leaves were dried at 70 °C, pulverized, and those that passed through an 80-mesh sieve were used. The moisture content was 2% by mass. Similarly, the dried product of amacha vine was pulverized, and those that passed through an 80-mesh sieve were used.

[0241] 80 parts by mass of the dried and pulverized tea leaves 20 parts by mass of the dried and pulverized amacha vine 15 parts by mass of methylcellulose 30 parts by mass of glycerin 30 parts by mass of propylene glycol 4 parts by mass of sodium carboxymethylcellulose 8 parts by mass of the xylitol / aqueous solution 0.5 parts by mass of glucomannan 20 parts by mass of water were put into a mixer and mixed for 15 minutes to obtain a mixture containing all the materials such as glucomannan.

[0242] The mixture thus prepared was mixed with a three-roll mill, and the process [means] of pressing the doctor blade against the roll to collect a sheet-like material was repeated 8 times to produce a heat-generating aromatic sheet with a thickness of 0.3 mm while also performing kneading and dispersion. However, when forming using a three-roll mill, it was difficult to make a sheet. Also, although it was made into a sheet, it was impossible to measure Evaluation A.

[0243] The heated aroma generating sheet thus produced was cut into a rectangle with a length of 150 mm and a width of 240 mm, supplied to a rotary cutter, and processed into a heated aroma generating filler with a width of 1.5 mm, a length of 240 mm, and a thickness of 0.3 mm. Fifty of these fillers were bundled and aligned in the longitudinal direction, and then wrapped with paper having a basis weight of 34 g / m 2 and glued to form a cylindrical heated aroma generating processed product. The inner diameter of this processed product was 6.9 mm. Further, it was cut into 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 volume filling ratio of the filler to its volume was 0.60.

[0244] (Example A) Using the heated aroma generating body produced in (Production Example A), an aroma cartridge of the type in which the heated aroma generating body is joined to a mouthpiece provided with a support member and a filter, as shown in FIG. 13, was produced. As the support member, a PE tube having an outer diameter of 6.9 mm and a through hole with an inner diameter of 4.0 mm was used. As the filter, a columnar molded body of acetyl cellulose fiber, having a length of 23 mm and wrapped with paper having a basis weight of 34 g / m 2 was used. The cartridge outer body was formed by winding and gluing paper having a basis weight of 38 g / m 2 two and a half times so as to have an inner diameter of 6.9 mm. Note that when using a paper tube formed by winding paper having a basis weight of 32 to 45 g / m 2 two and a half times, it is suitable as an aroma cartridge for inserting the portion of the heated aroma generating body into the heating element of a heat-not-burn smoking device and using it. Then, after inserting the support member and the filter from one end of the cartridge outer body to form a mouthpiece, and inserting the heated aroma generating body from the other end, paper having a basis weight of 40 g / m 2 was wound so as to overlap the mouthpiece portion to produce an aroma cartridge. However, as the filter, a filter in which no cavity, which is a suction optimization means, was formed was used in order to clarify the influence of the production method [apparatus] on the heated aroma generating substrate, that is, the difference in the function of the gas generation sustaining material.

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

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

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

[0248] (Comparative Example) An aromatic cartridge was produced in the same manner as in (Example A), except that the heated aromatic generator produced in (Comparative Production Example) was used. However, when producing the aromatic cartridge, the heated aromatic generator filler was too soft, making production difficult.

[0249] The following evaluations were performed on the heated aromatic generation sheet and the aromatic cartridge produced as described above. In addition to the following evaluations, <<Evaluation 1>> was also performed.

[0250] <<Evaluation A>> A tensile strength test of the heated aromatic generation sheet was conducted. The tensile strength test was performed using a commonly used tensile strength tester. As the sample, the heated aromatic generation sheet was cut into a width of 10.0 cm and a length of 22.0 cm, and the measurement was carried out at a distance of 20.0 cm between the clamps of the tensile strength test and a crosshead speed of 10 cm / min. The test environment was a room temperature of 20 °C and a humidity of 50%. By comparing the breaking strength, the heated aromatic generation sheets produced by each manufacturing method [apparatus] were evaluated, and it was found that a breaking strength of 3.9 N / mm 2 or more, preferably 5.0 N / mm 2 or more was found to be generally preferable in terms of molding processing, aromatic cartridge production, initial suction amount, initial flavor, and the change over time of the suction amount and flavor.

[0251] <<Evaluation B>> The heated smoking device used was the iQOS (registered trademark), a heated tobacco device manufactured by Philip Morris in the manner shown in Fig. 2(A). This heating element has a width of 4.5 mm, a length of 12 mm to the tip, and a thickness of 0.4 mm. Since the inner diameter of the chamber is 7 mm, the outer diameter of the flavor cartridge is set to 6.9 mm so that the flavor cartridge can be inserted into it without a gap. The heating element generates heat by the electric power supplied from a battery provided in the heated tobacco device body and reaches approximately 350°C. And by the built-in control system, one consumption is completed by 14 puffs with a conventional e-cigarette cartridge. When the smoking tobacco cartridge of this example is inserted, the flavor cartridge portion that appears outside from the downstream side of the e-cigarette device body is about 20 mm. Then, the flavor cartridges manufactured in this example and the comparative example were inserted into the chamber of the e-cigarette device, and a smoking test was conducted. Both the puff volume and the flavor are sensory evaluations in the oral cavity during smoking. In particular, the flavor was evaluated for the scent of tea immediately after manufacturing the flavor cartridge and after standing in <<Evaluation 1>>. The sensory test was conducted with 5 subjects. The evaluation criteria are as follows. Rank A: During smoking, there is a sufficient puff volume, no resistance to puffing, and the scent of tea can be enjoyed. Rank B: During smoking, the puff volume is insufficient, there is resistance to puffing, and the scent of tea is lacking.

[0252] <<Evaluation C>> The detachment of the filling after smoking was evaluated. The evaluation method [device] was to observe whether the heated flavor generating body side of the flavor cartridge after smoking was directed vertically downward and whether the heated flavor generating filling fell. The evaluation criteria are as follows. Rank A: No falling object was seen Rank B: There was a partial fall of the filling

[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 terms of any of the molding process, aroma cartridge production, initial suction amount and flavor, change over time in suction amount and flavor, and fusion of the heat-generating aroma-containing filler over time, and curing can further enhance the effect. Therefore, it is clear that the heat-generating aroma-containing base material with the binder added in portions, and further the heat-generating aroma-containing base material produced by subjecting it to a curing step [means], function as a gas-generation sustaining material for the aroma cartridge.

[0254]

Table 1

[0255] As described above, it was confirmed that the production method [apparatus] affects the internal structure of the heat-generating aroma-containing base material and functions as a gas-generation sustaining material for the aroma cartridge produced using the heat-generating aroma-containing base material produced by an appropriate production method [apparatus]. In the present invention, furthermore, a material that functions as a gas-generation sustaining material was found. It is inorganic particles.

[0256] The effect of the inorganic particles will be described with a specific example. For this purpose, as a conventionally used production method [apparatus], (Production Example 1) was adopted, and the influence of various inorganic particles on the gas-generation sustainability of the heat-generating aroma-containing base material produced by this production method [apparatus] was evaluated as follows.

[0257] (Production Example 1) was followed to produce the heated aroma generator and assemble the aroma cartridge. In this example, as shown in the spraying step [means] H2 in Fig. 32, the heated aroma generating sheet produced in (Production Example 1) was cut into a size of 12 mm in length × 1.5 mm in width (0.5 mm in thickness) to produce the heated aroma generating filler. After that, a predetermined amount of various inorganic particles was added, and a spraying and dusting step [means] was added so that the inorganic particles adhered uniformly to the surface of the heated aroma generating filler. Such a step [means] aims to uniformly adhere the inorganic particles to the surface of the heated aroma generating filler. Also, in this step [means], in order to confirm that the inorganic particles adhered to the surface of the heated aroma generating filler, the surface was observed with a microscope. Next, the heated aroma generating filler with the inorganic particles adhered was processed into a heated aroma generator and assembled into an aroma cartridge according to (Production Example 1). Furthermore, in order to clarify the effect of the inorganic particles, the filling rate was increased. Regarding the aroma cartridge produced in this way, <<Evaluation 1>> was carried out. Furthermore, using the heated electronic cigarette device described in <<Evaluation B>>, the following <<Evaluation 2>> was carried out.

[0258] <<Evaluation 2>> After confirming the dirt adhered to the heating element 113 when the aroma cartridge was used as shown in Fig. 2(C), the following evaluation was carried out. First, using the aroma cartridge of Comparative Example 1, 14 draws were performed for each one, and when 10, 20, 30, 40, and 50 draws were completed, the dirt adhered to the heating element was wiped off using gauze impregnated with ethanol, and the degree of the dirt was recorded. Then, when 50 draws were made of each of the aroma cartridges of this example produced using the heated aroma generating filler with various inorganic particles adhered to the surface, the dirt was collected in the same manner as in Comparative Example 1, and a comparative evaluation was made with the degree of dirt recorded in Comparative Example 1. The evaluation index was the number of cases where the degree of dirt when 50 draws were made of each of the aroma cartridges of this example was the same as the dirt when using the aroma cartridge of Comparative Example 1. Therefore, the smaller the number, the better.

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

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

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

[0262] (Example IV) From the heated aroma generating sheet produced in (Production Example 1), 1 part by mass of alumina particles having an average particle diameter of 5 μm was sprayed and applied to the entire surface of the heated aroma generating filler cut as described above so as to adhere to 100 parts by mass of the heated aroma generating filler, and it was made dazzling. After confirming by microscopic observation that alumina particles having a diameter of 10 μm to 50 μm were adhered to the heated aroma generating filler, a heated aroma generating body was produced using 0.29 g of the heated aroma generating filler having alumina particles on its surface. Then, an aroma cartridge was assembled from this heated aroma generating body and a mouthpiece. When the filling rate of the filler in this case was measured, it was 81%.

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

[0264] (Example VI) From the heated aroma generating sheet produced in (Production Example 1), 1 part by mass of silicon oxide particles having an average particle diameter of 0.5 μm was sprayed and dusted onto 100 parts by mass of the heated aroma generating filler cut as described above so as to adhere to the entire surface of the heated aroma generating filler. Also in this case, by microscopic observation, it was not possible to confirm that silicon oxide particles having a diameter of 10 μm to 50 μm were adhering to the heated aroma generating filler, but a heated aroma generating body was produced using 0.29 g of the heated aroma generating filler dusted with silicon oxide particles. Then, an aroma cartridge was assembled from this heated aroma generating body and a mouthpiece. When the filling rate of the filler in this case was measured, it was 81%.

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

[0266] (Comparative Example I) A heated aroma generating body was produced using 0.29 g of the heated aroma generating filler cut as described above from the heated aroma generating sheet produced in (Production Example 1) as it was. Then, an aroma cartridge was assembled from this heated aroma generating body and a mouthpiece. When the filling rate of the filler in this case was measured, it was 81%.

[0267] The above evaluation results are shown in Table 2. As is clear from the table, it can be seen that inorganic particles with a wide range of particle diameters function as gas generation sustaining materials regardless of their material. As is clear from the results of <<Evaluation 1>>, there is no fusion over time of the heated aromatic generating filler, and there are few changes over time in the gas emission amount, that is, both the gas suction amount and the flavor. The reason for such an effect is not clear, but it is considered as follows. When inorganic particles are present on the surface of the filler, the inorganic particles reduce the contact area between the fillers as spacers, and even when in a high-temperature state for a long time, there is an effect of inhibiting the fusion between the fillers due to the bleed-out of the aerosol former, and it is considered that the inorganic particles have an effect of suppressing the bleed-out of the aerosol former.

[0268]

Table 2

[0269] Furthermore, as is clear from <<Evaluation 2>>, it was confirmed that the inorganic particles also have an 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, there is a good effect, and when it is 5 μm or more, the contamination prevention effect is further enhanced. When the addition amount of the inorganic powder to be added is 0.01 to 5 parts by mass, there is a good effect, and when it is 0.1 part by mass or more, the contamination prevention effect is further enhanced. The reason for the effect of the inorganic particles on preventing the heating element is not clear, but it is speculated as follows. The fact that inorganic substances are difficult to thermally decompose, the inorganic particles polish the surface when the aromatic cartridge desorbs to the heating element and remove contaminants, and the inorganic particles reduce the contact area between the heating element surface and the heated aromatic generating filler, etc. can be mentioned.

[0270] To obtain such an effect, it is preferable that the inorganic particles have a diameter with an average particle size of 1 to 100 μm. When the average particle size is less than 1 μm, the effect of the inorganic particles is reduced. On the other hand, when it is 5 μm or more, it is more preferable because the effect of the inorganic particles is enhanced. For the same reason, it is even more preferable that it is 10 μm or more. Also, as the particle size increases, the filling rate of the filler decreases, but if it is 50 μm or less, the effect of the inorganic particles is large and it is possible to secure the minimum required filling rate.

[0271] Here, the minimum filling rate is closely related to the suction amount of the gas generated by heating. When the filling rate is less than 60%, the sufficient gas release amount by heating is small, the smoker's gas suction amount is insufficient, and the smoking feeling becomes insufficient. Therefore, a filling rate of more preferably 65% or more and even more preferably 70% or more is required. Conversely, when the filling rate exceeds 90%, there are few voids between the fillers, making smoking difficult and also making it difficult to insert into the heating element.

[0272] In addition, such a filling rate can be evaluated by a method of calculating the area ratio occupied by the heated aroma generating base material in the cross section of the heated aroma generating body. It was obtained by evaluating the void part without fillers using a digital microscope. A digital microscope (manufactured by Keyence Corporation: VHX-2000) was used, the magnification was set to 100 times and projected onto the display. Regarding the range for analyzing the image, it was set to the area where only the filler and the void part without the filler appear. In this case, for an observation sample diameter of 7.0 mm, it was 3.5 mm in width and 2.6 mm in length. In the above range, image analysis was performed using the attached software, and in the "automatic measurement mode", the "extraction mode" was set to "luminance". For the measurement, "standard" was selected, the "extraction parameter" was set to "bright", and the "threshold value" was selected so that the fillers and voids to be observed were separated. The filling rate was defined as the ratio of the fillers in the entire measurement area.

[0273] Also, the average particle size of the inorganic particles in the present invention is by laser diffraction / scattering type It was determined by the wet method using a particle size distribution measuring device. In the present invention, Microtrac MT3300III manufactured by Microtrac Bell was used. And the average particle size of the present invention is the median diameter D at which the volume-based distribution is accumulated to 50% for the range from 0.02 μm to 2000 μm. 50 is meant.

[0274] Furthermore, the presence of the inorganic particles in the present invention was confirmed not only by microscopic observation in 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 microscopic observation of the residue obtained by thermally decomposing the filler. Based on the observation results of about 10 fields when the magnification was appropriate and the field of view was 100 μm × 100 μm. Furthermore, that the inorganic particles in the residue are the added inorganic particles was confirmed with a scanning electron microscope equipped with X-ray microanalysis (XMA).

[0275] The addition amount of the inorganic particles needs to be at least 0.001 part by mass, more preferably 0.01 part by mass or more, and even more preferably 0.05 part by mass or more with respect to 100 parts by mass of the filler in order for the effect to be exhibited. On the contrary, if it exceeds 10 parts by mass with respect to 100 parts by mass of the filler, the filling rate of the filler decreases, which affects the gas suction amount and the flavor. From such a viewpoint, it is more preferably 5 parts by mass or less, and even more preferably 2 parts by mass or less.

[0276] The inorganic substances that can be used as the inorganic particles of the present invention are 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. Further, 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] Thus, the inorganic particles can be attached to the heated aroma-generating base material in the spraying step [means] H2 of FIG. 32, but can also be attached in the spraying step [means] S4 of FIG. 32. Further, as shown in FIGS. 28 to 31, an inorganic particle-containing heated aroma-generating base material can be produced by adding inorganic particles to the heated aroma-generating composition. In the case of this method [apparatus], although the inorganic particles do not exist only on the surface of the heated aroma-generating base material, it has been confirmed that the effects of the inorganic particles are exhibited. Therefore, it is presumed 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 the fusion between the heated aroma-generating base materials, but also hinder the movement of constituent materials such as aerosol formers, non-tobacco materials, and binders inside the heated aroma-generating base materials. This presumption is based on the fact that in polymer materials, when inorganic particles are used as fillers, they play the role of crosslinking points and improve chemical properties such as heat resistance and chemical resistance, and physical properties such as tensile strength and elastic modulus.

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

Industrial Applicability

[0279] Since the present invention is a harmless aroma derived from plants such as tobacco and its related plants in the Solanaceae tobacco genus and does not contain its components, it can provide an aroma cartridge that allows both experienced users of flame smoking and first-time smokers to enjoy smoking with a tobacco-like feeling. Therefore, it is a new smoking device that not only allows smokers themselves to enjoy smoking without having an adverse health effect on surrounding non-smokers, but also has a soothing effect that brings alpha waves to the brain and is useful for promoting health and beauty. Moreover, since it is an aroma cartridge equipped with gas suction optimization means and a gas generation sustaining material, it has the characteristic that even when stored for a long period of time, there is no change in the suction amount of smoke and aroma components and puffing. Therefore, the technology related to the aroma cartridge of the present invention has the possibility of being widely applied to incense sticks, burning incense, rubbed incense, applied incense, etc., and aromatherapy.
