Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, the aroma cartridge can take various forms depending on the specifications of the suction device. For example, the aroma cartridge is often formed in a cylindrical shape, but in a suction device in which the electric heating means is formed in a blade shape or a pin shape, the diameter of the aroma cartridge is set so that the electric heating means can be inserted into the aroma base material that generates an aerosol by heating.

[0006] On the other hand, in a suction device in which the electric heating means is formed in a cylindrical shape or the like so as to be able to heat the outer peripheral surface of the aromatic cartridge, since it is not necessary to insert the electric heating means into the aromatic base material, it is possible to set the diameter smaller than that of the aromatic cartridge used in a suction device formed in a blade shape or the like.

[0007] Regardless of its form, it is desired by users that the smoking feeling and the smokable time of the aromatic cartridge be constant. For this reason, the amount of the aromatic base material that generates the aerosol filled in the aromatic cartridge preferably has a certain amount or more regardless of the form of the aromatic cartridge.

[0008] When the axial length of the aromatic base material filled in the aromatic cartridge becomes long, there is a problem that the ventilation resistance in the aerosol flow path becomes high and it is difficult to obtain a sufficient aerosol suitable for smoking.

[0009] Further, in order to reduce the ventilation resistance in the aerosol flow path, if the amount of the aromatic base material is reduced, the aromatic base material may move to one end side or the other end side of the cartridge. When the aromatic base material moves to such a position, when the aromatic cartridge is attached to the suction device, the aromatic base material is not arranged in the region (heating region) that can be heated by the electric heating means of the suction device, and there is a problem that an aerosol cannot be appropriately generated.

[0010] The present invention has been made in view of the above problems, and an object thereof is to provide an aromatic cartridge that has air permeability suitable for smoking and can generate a sufficient aerosol regardless of the form of the aromatic cartridge.

Means for Solving the Problems

[0011] The aromatic cartridge of the present invention is mounted on a suction device having electric heating means, and in the aromatic cartridge that generates an aerosol by being heated by the electric heating means, it has a cylindrical cover and an aromatic base material that is housed in the cover and generates an aerosol containing an aromatic component when heated, and the aromatic base material is provided at a plurality of locations with a predetermined interval in the axial direction of the cover.

[0012] According to the aromatic cartridge of the present invention, since the aromatic base material is provided at a plurality of locations with a predetermined interval in the axial direction of the cover, even when the heating region of the suction device is long in the axial direction, the aromatic base material can be dispersedly arranged in the heating region, and the heat in the heating region can be evenly transmitted to the aromatic base material. That is, the ventilation resistance due to the aromatic base material in the axial direction of the cover can be reduced according to the interval, as compared with the case where the aromatic base material is arranged over the entire heating region. Further, by intermittently arranging the aromatic base material in the axial direction of the cover, it becomes possible to alternately arrange a region with low ventilation resistance and a region with high ventilation resistance. Therefore, even if the flow rate of the gas containing the aerosol becomes slow in the region with high ventilation resistance, it can be increased in the subsequent region with low ventilation resistance. As a result, it becomes possible to reduce the ventilation resistance in the axial direction of the cover, as compared with the case where the aromatic base material is arranged together at one position. Therefore, it becomes possible to improve the ease of sucking the aerosol generated from the aromatic base material. Further, since the aerosol and air can be mixed in an appropriate distribution, it becomes possible to improve the flavor.

[0013] In the aromatic cartridge of the present invention, it preferably has a partition provided between two of the aromatic base materials arranged close to each other in the cover, and the partition has air permeability with respect to the axial direction of the cover.

[0014] According to such an aspect, by disposing a partition wall between the two fragrance base materials, it is possible to regulate the movement of the fragrance base material disposed on the distal end side of the cover toward the proximal end side of the cover and the movement of the fragrance base material disposed on the proximal end side of the cover toward the distal end side of the cover by the partition wall, and it is possible to define the interval in the axial direction of the cover provided between the two fragrance base materials by the partition wall. Further, since the partition wall has air permeability with respect to the axial direction of the cover, it is possible to ensure the air permeability at the predetermined interval.

[0015] In the fragrance cartridge of the present invention, it is preferable that the fragrance base material is granular and has a lid member that closes the distal end side of the cover and has air permeability with respect to the axial direction of the cover.

[0016] According to such an aspect, it is possible to prevent the fragrance base material from flowing out to the outside through the opening formed on the distal end side of the cover.

[0017] In the fragrance cartridge of the present invention, among the plurality of fragrance base materials, a regulating member is provided in contact with the fragrance base material disposed on the most proximal end side of the cover and regulates the movement of the fragrance base material toward the proximal end side of the cover, and it is preferable that the regulating member has air permeability with respect to the axial direction of the cover.

[0018] According to such an aspect, it becomes possible to hold the fragrance base material disposed on the most proximal end side of the cover at a predetermined position within the cover by the regulating member. As a result, when the fragrance cartridge is attached to the suction device, the fragrance base material can be held at a position suitable for heating by the electric heating means.

[0019] In the fragrance cartridge of the present invention, it is preferable that the partition wall is made of at least one selected from a cotton-like member, a porous member, a honeycomb structure, a mesh structure, and a paper-wound member having a through hole formed to penetrate from one end to the other end along the axial direction of the cover.

[0020] In the fragrance cartridge of the present invention, it is preferable that the fragrance base material is dispersedly arranged within the heating region of the electric heating means in a state of being attached to the suction device.

[0021] When the fragrance cartridge is attached to the suction device, the fragrance base material is provided so as to be dispersedly arranged within the heating region of the electric heating means, whereby the heat generated by the electric heating means can be efficiently transmitted to each fragrance base material. As a result, it becomes possible to generate an aerosol well-balancedly from each fragrance base material.

Effects of the Invention

[0022] According to the fragrance cartridge of the present invention, it is possible to reduce the ventilation resistance in the axial direction of the cover. For this reason, it is possible to improve the ease of sucking the aerosol generated from the fragrance base material. Further, since the aerosol and air can be mixed in an appropriate distribution, it is possible to improve the flavor.

Mode for Carrying Out the Invention

[0024] [Embodiment 1] Hereinafter, with reference to the drawings, an embodiment of the aromatic cartridge according to the present invention will be described. FIG. 1 is a perspective view of the aromatic cartridge according to the present embodiment. FIG. 2 is a developed perspective view of the aromatic cartridge. FIG. 3 is a cross-sectional view of the aromatic cartridge of FIG. 1. FIG. 4 is an explanatory view showing a state when the aromatic cartridge according to the present embodiment is attached to a suction device.

[0025] [Configuration of Aromatic Cartridge 100] As shown in FIGS. 1 and 2, the aromatic cartridge 100 can be used, for example, for a cartridge of a heated tobacco. Hereinafter, an example in which the aromatic cartridge 100 is a cartridge used for a heated tobacco which is a suction device having an electric heating means will be described.

[0026] The aromatic cartridge 100 includes a cylindrical cover 10, an aromatic base material 20 accommodated at one end side of the cover 10, and a filter 30 accommodated at the other end side of the cover 10. Incidentally, in the present embodiment, the aromatic base materials 20 are provided at two locations with a predetermined interval in the axial direction of the cover 10. A partition wall 40 is provided between the aromatic base materials 20.

[0027] The cover 10 is composed of a wrapper 11 that covers the aromatic base material 20 and a tip paper 12 that further covers the outer peripheral portion of the filter 30 from the outside of the wrapper 11. The wrapper 11 is joined to the tip paper 12 by means such as adhesion or heat fusion.

[0028] The roll paper 11 and the chip paper 12 can be composed of, for example, paper, synthetic resin film, metal foil, etc., and may be a composite sheet in which these are laminated. Also, an adhesive or fusible layer such as an adhesive layer or a hot melt layer may be formed on the inner surface of the roll paper 11 and the chip paper 12.

[0029] In the present embodiment, the roll paper 11 serves to form the aromatic base material 20 together in a columnar shape. The roll paper 11 serves to connect the aromatic base material 20, the partition wall 40, and the filter 30. The chip paper 12 serves to reinforce the portion (mouthpiece) where the user holds the aromatic cartridge 100 in the mouth. Note that the cover 10 is not limited to being configured such that the roll paper 11 and the chip paper 12 are individually formed, and for example, may be configured of a single sheet in which the roll paper 11 and the chip paper 12 are integrated.

[0030] In the present embodiment, as also shown in FIGS. 2 and 3, the two aromatic base materials 20, the partition wall 40, and the filter 30 are arranged along the axial direction from one end side to the other end side of the cover 10. The space surrounded by the inner wall of the cover 10 serves as the flow path of the aerosol.

[0031] The aromatic base material 20 can be, for example, an aggregate of rod-shaped, strip-shaped, powder-shaped, granular, pellet-shaped, small piece-shaped, sheet-shaped, fibrous, porous, paste-shaped, or block-shaped components. In the present embodiment, the aromatic base material 20 is formed in a cylindrical shape as a whole by strip-shaped components. Note that the aromatic base material 20 needs to have appropriate air permeability, and the air permeability is obtained by gaps between the filled components, gaps formed by cracks due to drying of the filled components, porous tissues possessed by the components themselves, etc.

[0032] The aromatic base material 20 can generate an aerosol containing aromatic components by being heated by the electric heating means of a heated cigarette, which is a suction device. The aromatic base material 20 is not limited to tobacco plants, and preferably used is one containing a pulverized and dried product of a plant using a non-tobacco plant as a raw material, an aerosol former capable of generating an aerosol, and a heat-fusible substance that melts when heated. The configuration of the aromatic base material 20 will be described later.

[0033] In addition, in the present embodiment, two aromatic base materials 20 are arranged at a predetermined interval, but the number of aromatic base materials 20 is not limited, and three or more aromatic base materials may be arranged at a predetermined interval respectively.

[0034] The filter 30 preferably has a certain air permeability with respect to the mainstream smoke or aerosol generated from the aromatic base material 20, and has a function of capturing solid particles contained in the mainstream smoke or aerosol and adsorbing harmful components and the like. The shape of the filter 30 is not particularly limited, and any shape that can be wrapped by the cover 10 may be used.

[0035] As the filter 30, for example, an acetate filter using acetate fiber, a charcoal filter containing activated carbon in the acetate filter, an AFT (Advanced Filter Technology) (registered trademark) having a plurality of grooves formed by being recessed from the outer peripheral surface of the filter 30 in the axial direction of the cover 10, etc. can be used. In the present embodiment, the filter 30 is fixed to the inner peripheral surface of the base material 12 of the cover 10 by fixing means such as adhesion and welding.

[0036] As also shown in FIGS. 2 and 3, the partition wall 40 is arranged adjacent to each of the two aromatic base materials 20. The partition wall 40 can have a shape with an outer peripheral surface corresponding to the shape of the inner peripheral surface of the cover 10. In the present embodiment, the partition wall 40 is formed in a cylindrical shape as a whole. The partition wall 40 is fixed to the cover 10 by fixing means such as adhesion and welding, and in the present embodiment, it is fixed to the inner peripheral surface of the rolling paper 11.

[0037] The partition wall 40 is disposed between two fragrance base materials 20 that are arranged close to each other within the cover 10. The partition wall 40 has air permeability with respect to the axial direction of the cover 10. The air permeability of the partition wall 40 may have air permeability suitable for smoking. For example, it may have at least the same degree of air permeability as the filter 30.

[0038] In this embodiment, the partition wall 40 is formed in a hollow cylindrical shape having a through hole 41 formed therethrough from one end to the other end, but may be composed of a columnar member having no through hole 41. The partition wall 40 is preferably made of a material having heat resistance with respect to the temperature range (for example, 180 to 400 ° C) heated by the electric heating means of the heated tobacco. Examples of such heat-resistant materials include paper, resin, rubber, wood, metal, and ceramic. As the partition wall 40, for example, a paper roll member formed in a cylindrical shape having a spiral gap when viewed from the end face by winding a sheet-like paper in a spiral shape from the end can also be used.

[0039] The shape of the partition wall 40 is not limited as long as it has a structure having air permeability from the tip side to the base end side of the cover 10 and has a function of restricting the movement of the fragrance base material 20 disposed on the tip side toward the base end side. The partition wall 40 is preferably composed of at least one selected from, for example, a cotton-like member, a porous member, a honeycomb structure, a mesh structure, and the aforementioned paper roll member. Each fragrance base material 20 may be arranged at a predetermined interval in the axial direction of the cover 10, and the partition wall 40 does not necessarily have to be provided in the fragrance cartridge 100. For example, if each fragrance base material 20 can be fixed to the inner surface of the cover 10 by the adhesiveness of the material itself or an adhesive, etc., the partition wall 40 is not necessarily required.

[0040] As shown in FIG. 4, the heated tobacco 50 has an insertion hole 51 formed so that the fragrance cartridge 100 can be inserted. Inside the heated tobacco 50, electric heating means 52 capable of raising the temperature of the inner peripheral surface of the insertion hole 51 is provided.

[0041] The electric heating means 52 includes, for example, an electric resistance material and can be heated to 150 to 400 °C when powered. Examples of the electric resistance material include, but are not limited to, semiconductors such as doped ceramics, "conductive" ceramics (e.g., molybdenum disilicide), carbon, graphite, metals, metal alloys, and composite materials made from ceramic materials and metal materials.

[0042] In the composite material, the electric resistance material can be embedded in, encapsulated by, or coated with an insulating material, or vice versa. As an alternative to the electric resistance material, the electric heating means 52 can include an infrared heating element, an optical source, or an induction heating element.

[0043] In the insertion hole 51, a region that can be heated to 150 to 400 °C by the electric heating means 52 is defined as a heating region R1, and the other regions are defined as non-heating regions R2.

[0044] The aroma cartridge 100 is attached to the heat-not-burn tobacco 50 by being inserted into the insertion hole 51 of the heat-not-burn tobacco 50. When the aroma cartridge 100 is attached to the heat-not-burn tobacco 50, all of the aroma base material 20 is disposed in the heating region R1 of the insertion hole 51.

[0045] In this way, each of the aroma base materials 20 is dispersed and disposed in the heating region R1 of the heat-not-burn tobacco 50, so that the heat of the electric heating means 52 is favorably transmitted to each of the aroma base materials 20, making it possible to generate an appropriate amount of aerosol for smoking. Further, by disposing a highly breathable partition wall 40 between the aroma base materials 20, the ventilation resistance can be set within an appropriate range.

[0046] [Configuration of the aroma base material 20] The aromatic base material 20 includes a pulverized and dried product of a plant that generates an aroma when heated, and an aerosol former that generates an aerosol when heated. Therefore, the aromatic base material 20 can generate an aerosol containing an aromatic component when heated. Incidentally, the aromatic base material 20 preferably contains at least one of a heat-fusible substance that melts when heated, catechin, crosslinked polyvinylpyrrolidone and / or polyvinylpyrrolidone, and a fragrance.

[0047] In addition to this, the aromatic base material 20 may also include, for example, a fragrance that can assist the aroma emitted from the pulverized and dried product of the plant, a molding agent that can improve the moldability of the aromatic base material 20, a binder that contributes to binding and integrating the aerosol former and the pulverized and dried product of the plant, a sorbent that can retain the fragrance in the aromatic base material 20, and a preservative that can improve the storage stability of the aromatic base material 20.

[0048] (Pulverized and dried product of a plant) Examples of the pulverized and dried product of the plant include tobacco leaves and stems, as well as leaves, stems, flowers, seeds, fruits, barks, and roots of non-tobacco plants.

[0049] The pulverized and dried plant material includes, in particular, Chinese tea, black tea, rose, plants of the genus Osmanthus of the family Oleaceae, lavender, saffron flowers, Chinese ginger, shallots, garlic, onions, the rhizomes of konjac, quince, plants of the genus Citrus of the family Rutaceae (such as daidai, unshu mandarin, summer daidai, ponkan, hassaku, iyokan, ichang lemon, karatachi, orange, mandarin orange, kabosu, kishu mandarin, knott, grapefruit, kouji, sanbokan, citron, jabara, sudachi, tachibana, tangor, natsumikan, hanayuzu, hyuga nats, hirami lemon (sour orange), buntan (pomelo), yuzu, lime, lemon, kobumikan, etc.), plants of the genus Prunus of the family Rosaceae, apple, pineapple, mango, kumquat, melon, pomegranate, ume, apricot, blueberry, plants of the genus Fragaria of the family Rosaceae, raspberry, banana, and the fruits of grapes, peppermint plants of the genus Mentha of the family Lamiaceae (such as peppermint, Japanese mint, apple mint, water mint, Corsican mint, pennyroyal mint, etc.), spearmint plants of the genus Mentha of the family Lamiaceae (such as spearmint, horsemint, midori-hakka, chirimen-hakka, ginger mint, etc.), dog mint, kouzui-hakka (lemon balm), kidachi-hakka (savory), yanagi-hakka (hyssop), and at least one or more selected from the aerial stems and leaves of plants of the genus Nicotiana of the family Solanaceae. This is suitable for providing a pleasant fragrance to the user, but is not limited thereto.

[0050] The pulverized and dried plant material preferably has the three elements of fragrance, which is defined as the fragrance wafting from the aroma cartridge 100 itself, aroma, which is defined as the fragrance wafting in the space when the aroma cartridge 100 is heated, and flavor, which is defined as the fragrance wafting in the mouth when the aroma cartridge 100 is heated and inhaled together with the aerosol.

[0051] As the pulverized and dried plant material (hereinafter also referred to as fragrance material) constituting the fragrance, it is preferable to include at least one or more selected from Chinese tea, black tea, rose, plants of the genus Osmanthus of the family Oleaceae, lavender, saffron flowers, and the aerial stems and leaves of plants of the genus Nicotiana of the family Solanaceae.

[0052] As the pulverized and dried product of the plant constituting the aroma (hereinafter also referred to as the aroma material), it preferably contains at least one or more selected from galangal, eschalot, garlic, onion, the rhizome of konjac, and the aerial stems and leaves of the plant of the tobacco species of the genus Nicotiana of the Solanaceae family.

[0053] As the pulverized and dried product of the plant constituting the flavor (hereinafter also referred to as the flavor material), it preferably contains at least one or more selected from Chinese quince, plants of the genus Citrus of the Rutaceae family (daidai, unshu mikan, natsudaidai, ponkan, hassaku, iyokan, ichang lemon, karatachi, orange, mandarin orange, kabosu, kishu mikan, knott, grapefruit, koji, sanbokan, citron, jabara, sudachi, tachibana, tangor, natsumikan, hanayuzu, hyuga natsu, hirami lemon (seyval), buntan (pomelo), yuzu, lime, lemon, kobumikan, etc.), plants of the peach species of the genus Prunus of the Rosaceae family, apple, pineapple, mango, kumquat, melon, pomegranate, ume, apricot, blueberry, plants of the genus Fragaria of the Rosaceae family, raspberry, banana, the fruit of grape, pepper mint plants of the genus Mentha of the Lamiaceae family (peppermint, Japanese mint, apple mint, water mint, Corsican mint, pennyroyal mint, etc.), spearmint plants of the genus Mentha of the Lamiaceae family (spearmint, horse mint, green mint, chili mint, ginger mint, etc.), dog mint, lemon balm, savory, hyssop, and the aerial stems and leaves of the plant of the tobacco species of the genus Nicotiana of the Solanaceae family.

[0054] (Aerosol form) An aerosol former is added to generate an aerosol when the aromatic base material 20 is heated. As the aerosol former, for example, 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.

[0055] (Thermally fusible substance) The thermally fusible substance is added to dissolve and vaporize the aromatic components generated from the aromatic base material 20 by melting at a relatively low temperature, so as to be easily dissipated together with the aerosol former. Also, the thermally fusible substance serves to fix the aromatic source material and / or the fragrance at normal temperature.

[0056] The thermally fusible substance has a melting point in the range of 50 to 100 °C, preferably in the range of 50 to 80 °C, and more preferably in the range of 60 to 67 °C. If the melting point of the thermally fusible substance is less than 50 °C, the thermally fusible substance may melt during high-temperature periods such as summer, resulting in stickiness. Also, if the melting point of the thermally fusible substance exceeds 100 °C, the thermally fusible substance may not be sufficiently melted at the initial stage of the temperature-rising process of the aromatic base material, and the fragrance of the aerosol may tend to be insufficient immediately after the end of the temperature-rising process by the heated tobacco.

[0057] Incidentally, the melting point of the thermally fusible substance can be measured, for example, in accordance with the melting point measurement method of paraffin wax specified in JIS K2235. That is, using a predetermined melting point tester, putting the melted sample into the tester, reading the indication of the melting point thermometer every 15 seconds, and measuring the temperature when the temperature drop is within a certain range (the difference within 0.1 °C continues 5 times) as the melting point.

[0058] The heat-melting substance is preferably in powder form. The average particle size of the heat-melting substance is preferably 125 to 355 μm, more preferably 150 to 300 μm, and even more preferably 180 to 250 μm. Incidentally, the average particle size can be measured by, for example, a laser diffraction particle size distribution measuring device. The average particle size in the present invention means the median diameter.

[0059] If the average particle size of the heat-melting substance is too large, its total surface area becomes small, so the contact opportunity with the heat source decreases. As a result, the heat-melting substance is not sufficiently melted, and the concentration of the aromatic component in the aerosol immediately after the end of the temperature rise process tends to decrease.

[0060] If the outer diameter of the heat-melting substance is too small, it becomes difficult to form a sea-island structure in which the heat-melting substance is dispersed in the aromatic base material 20 described later. As a result, since each of the heat-melting substances exists in the aromatic base material 20 as an aggregated lump, a region where the melting rate due to contact with the heat source decreases is formed, and the concentration of the aromatic component in the aerosol immediately after the end of the temperature rise process tends to decrease. The heat-melting substance is preferably contained in the aromatic base material 20 in an amount of 2 to 20% by mass, preferably 3 to 15% by mass, and more preferably 5 to 15% by mass.

[0061] The blending amounts of the aromatic source material, the aerosol former, and the heat-melting substance are preferably 55 to 75% by mass, 20 to 40% by mass, and 2 to 15% by mass, respectively, and more preferably 60 to 70% by mass, 25 to 35% by mass, and 3 to 10% by mass, in order to balance the volatilization amounts of the smoke component and the aromatic component.

[0062] The thermally fusible substance is not particularly limited as long as it is "an organic compound that exhibits a melting point or softening point when heated and becomes a non-Newtonian fluid". The thermally fusible substance is generally preferably an organic compound called wax and paraffin wax, and petroleum-based natural wax, synthetic wax, plant-based natural wax, and animal-based natural wax, which are typical waxes and paraffin waxes, can be used. In addition, various tackifiers (adhesion promoters) to which rosin, which is also used as wax and paraffin wax, belongs can be used. These can be used alone or as a mixture containing at least one or more selected from among them.

[0063] As the thermally fusible substance, plant-based natural wax and animal-based natural wax are preferably used from the viewpoints of having a preferable melting point and imparting flavor. Examples of plant-based natural wax include, for example, bayberry wax, urushi wax , carnauba wax, sugarcane wax, palm wax, candelilla wax, and the like. Also as animal-based natural wax, beeswax, spermaceti wax, ibota wax, wool wax, shellac, and the like can be used. These are easy to obtain those having a melting point in the range of 50 to 100°C as defined in the present invention , and since they have a preferable flavor by themselves, they can enhance the aroma of the aerosol. Among these natural waxes, carnauba wax, beeswax, petrolatum, and paraffin wax are particularly preferred, and beeswax having a melting point of 62 to 65°C and rich in aromatic components is most preferred.

[0064] Plant-based natural wax and animal-based natural wax mainly consist of esters of fatty acids and aliphatic alcohols. Plant-based natural wax and animal-based natural wax are mixtures of esters of fatty acids and aliphatic alcohols having various carbon numbers, and also contain free fatty acids, free aliphatic alcohols, hydrocarbons, and the like. Therefore, plant-based natural wax and animal-based natural wax are characterized by having a wide molecular weight distribution, a wide temperature range of melting point, and high viscosity during melting.

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

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

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

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

[0069] As such a paraffin wax, for example, a standard product manufactured by Nippon Seiro Co., Ltd. Paraffin Wax-115, 120, 125, 130, 135, 140, 145 , 150, and 155, all of which are preferably used. Waxes, for example, are high-purity refined paraffin waxes, which are special products manufactured by Nippon Seiro Co., Ltd. Among them, HNP series products, SP series products for specific applications, and EMW series products mainly composed of isoparaffin produced by a special manufacturing method are also preferably used. In addition, microcrystalline waxes, for example, any of the Hi-Mic series manufactured by Nippon Seiro Co., Ltd. are preferably used.

[0070] As synthetic waxes, for example, Fischer-Tropsch waxes, polyethylene (PE) waxes, modified PE waxes, polypropylene (PP) waxes, modified PP waxes, fatty acid amides, fatty acids, aliphatic alcohols, poly oxyalkylene glycols, polyoxyethylene alkyl ethers, polyoxyethyl lene alkyl amines, etc. can be preferably used.

[0071] In particular, since Fischer-Tropsch waxes are linear hydrocarbon-based organic compounds, they have low melt viscosity and surface energy during heat melting, and also have little interaction with aerosol formers and aromatic components.

As described above, the fixative can retain fragrance agents such as a cooling agent and a fragrance in the heated fragrance generating material 20.

[0090] As one of the preferable embodiments of the fixative, a fixative that retains the compound in the fragrance generating base material 2 0 by adsorbing the compound can be used. For example, when the compound is menthol case, menthol has a phenolic hydroxyl group. Therefore, as the fixative, for example, crosslinked polyvinylpyrrolidone (PVPP: Polyvinylpolypyrrolidone), polyvinylpyrrolidone (PVP: Polyvinylpyrrolidone) that can adsorb a phenolic hydroxyl group can be used.​ Hydrophilic crosslinked polymers such as the above can be used.

Therefore, as a sorbent, it has a mutual interaction with five-membered heterocyclic compounds containing nitrogen. Crosslinked PVP may be used, which is believed to form the effect.

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

[0093] In addition, the sorbent is capable of retaining the compound in the aroma-generating substrate 20 by encapsulating the compound. A sorbent that uses cyclodextrin can be used. It is possible.

[0099] The microcrystalline cellulose preferably has an average particle size of 70 to 120 μm. When the average particle size of the crystalline cellulose is less than 70 μm, the shrinkage of the aromatic base material 20 is suppressed and the aromatic group is easily absorbed. It tends to be difficult to prevent adhesion between the material 20 and the molding machine. If the average particle size of the powder exceeds 120 μm, the aromatic base material 20 tends to break easily. The average particle size of the microcrystalline cellulose is measured by a laser diffraction particle size distribution measuring device. In the present invention, the average particle size means the median diameter.

[0100] The mass average molecular weight (Mw) of microcrystalline cellulose is 20,000 to 60,000. It is preferable that the mass average molecular weight (Mw) of the microcrystalline cellulose is less than 20,000. If present, there is a tendency for the effect of suppressing the shrinkage of the fragrance base material 20 to be poor. Microcrystalline cellulose When the mass average molecular weight (Mw) of exceeds 60,000, the fragrance base material 20 tends to break easily tendency.

[0101] The molding agent is preferably contained in an amount of 2 to 25% by mass, more preferably 3 to 20% by mass, based on 100% by mass of the total amount of the fragrance source material, aerosol former, and heat-melting substance.

[0102] (Binder) The binder is used to bind raw materials such as the fragrance source material, aerosol former, and heat-melting substance that constitute the fragrance base material. As the binder, for example, polysaccharide-based polymers, cellulose-based polymers, calcium carbonate, etc. can be used. As the binder, for example, polysaccharide-based polymers, cellulose-based polymers, calcium carbonate, etc. can be used. As the binder, for example, polysaccharide-based polymers, cellulose-based polymers, calcium carbonate, etc. can be used.

[0103] Examples of polysaccharide-based polymers include konjac mannan (glucomannan), guar gum, pectin, carrageenan, tamarind seed gum, gum arabic, soy polysaccharides, locust bean gum, karaya gum, xanthan gum, agar, etc. From the viewpoints of strength and the above-mentioned moldability, polysaccharide-based polymers, glucomannan, guar gum, pectin, carrageenan, tamarind seed gum, locust bean gum, karaya gum, and xanthan gum are preferred, and neutral polysaccharides such as glucomannan, guar gum, tamarind seed gum, and locust bean gum are more preferred. gum, and locust bean gum are more preferred. gum, and locust bean gum are more preferred. gum, and locust bean gum are more preferred.

[0105] As the binder, it is preferable to use a polysaccharide-based polymer and a cellulose-based polymer in combination. In this case, as the polysaccharide-based polymer, glucomannan, guar gum, tamarind seed gum, locust bean gum are preferably used. Also, as the cellulose-based polymer the sodium salt of CMC, the potassium salt of CMC, the sodium salt of carboxyethyl cellulose, the potassium salt of carboxyethyl cellulose are preferably used.

The preservative is preferably contained in an amount of 0.005 to 0.04% by mass based on the total amount of 100% by mass of the fragrance source material, the aerosol formulator, and the heat-meltable substance.

[0109] Next, a method for manufacturing the aromatic base material 20 will be described. FIG. 5 shows an embodiment of the manufacturing process of the aromatic base material 20. As shown in FIG. 5, a mixing step of mixing a raw material (A) containing a fragrance material, which is a pulverized and dried product of a plant constituting the fragrance, a flavor material, which is a pulverized and dried product of a plant constituting the flavor, etc., and a raw material (B) containing an aroma material, which is a pulverized and dried product of a plant constituting the aroma, etc., is performed. The mixing step is performed at a temperature below the melting point of the heat-meltable substance. The mixing step can be performed, for example, using a known mixer.

[0110] The raw material (A) contains a raw material (A1) containing a fragrance material, which is a pulverized and dried product of a plant constituting the fragrance, a flavor material, which is a pulverized and dried product of a plant constituting the flavor, and a heat-meltable substance, an aqueous alcohol solution of microcrystalline cellulose, and an aqueous alcohol solution of a binder​​​​​​​​ Raw material (A3) containing an aqueous solution of rue and an aqueous alcohol solution of a sorbent, and an aerosol former is obtained by mixing raw material (A4) containing an aerosol former, a fragrance, and a forming agent and aging them .

[0111] In addition, the mixing of raw materials (A1) to (A4) is carried out below the melting point of the heat-melting substance. Also, this mixing step can be carried out using, for example, a known mixer.

[0112] Raw material (A1) is obtained by pulverizing a fragrance material after sterilization.

[0113] Raw material (A2) is obtained by pulverizing a mixture of a flavor material and a heat-melting substance after sterilization . Specifically, as shown in Fig. 6, after sterilizing the flavor material, it is pulverized to a predetermined size . Also, the powdery heat-melting substance is heated and mixed at a temperature equal to or higher than the melting point of the heat-melting substance and then cooled, and then pulverized to a predetermined size. The pulverized product and the powdery flavor material are compression-shear mixed, cooled, and then pulverized to prepare raw material (A2). It is preferable to do so.

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

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

[0116] The aging is preferably carried out for 3 to 14 days under temperature conditions of, for example, 15 to 30°C. Aging ​From the perspective of retaining aromatic components, it is preferably carried out under a temperature condition of 20 ± 2°C for 4 to 7 days. If the temperature exceeds 30°C or the aging period exceeds 14 days, the likelihood of mold growth and corruption tends to increase.

[0117] Raw material (B) is obtained by mixing raw material (B1) containing an aromatic material which is a pulverized and dried product of a plant constituting the aroma and raw material (B2) containing a preservative. Incidentally, the mixing of raw materials (B1) and (B2) can be carried out using, for example, a known mixer. Raw material (B1) is obtained by pulverizing the aromatic material after sterilization. Raw material (B2) is obtained by dissolving the preservative in pure water.

[0118] By performing the mixing step of mixing raw material (A) and raw material (B) in this way, a sea-island structure in which powder of a heat-melted substance in which an aromatic source material is mixed in the aromatic base material 20 is dispersed can be formed.

[0119] Next, the mixture obtained in the mixing step is subjected to compression and shear processing to form it into a sheet shape. In the compression and shear processing, for example, it can be carried out using three rolls. By performing the compression and shear processing with three rolls, air can be entrapped and it can be formed into a sheet shape without evaporating water.

[0120]

[0121]

[0122] The sheet thus obtained has a porous structure containing air inside. As a result, it becomes possible to obtain an aromatic base material 20 with a low density. Also, since the rolls of the three rolls have extremely flat surfaces, the surface of the sheet is formed flat.​​​​​​​​​That is, the aromatic base material 20 is porous and contains air inside during compression / shearing processing, so it has a low density and its surface is formed flat without unevenness. .

[0123] The mixture formed into a sheet shape by compression / shearing processing is cut into a predetermined shape and size, and a cutting process is performed. The sheet-like mixture is processed into, for example, a strip shape.

[0124] In this way, by performing the mixing process, the compression / shearing process, and the cutting process below the melting point of the heat-melting substance, it is possible to prevent the heat-melting substance from spreading throughout the aromatic base material 20 due to melting, and to maintain the sea-island structure of the heat-melting substance in the aromatic base material 20.

[0125] When a sea-island structure in which powders of the heat-melting substance mixed with the aromatic source material are dispersed is formed in the aromatic base material 20, the heat-melting substance is dispersed and arranged in an island shape in the aromatic base material 20.

[0126] When the heat-melting substance is dispersed and arranged in an island shape in the aromatic base material 20 rather than being impregnated in the aromatic source material, it becomes easier to flow when melted, and it becomes easier to contain the aromatic components generated from the aromatic source material. In addition, the flowing heat-melting substance comes into contact with the aerosol former, and it is possible to make it easier for the aromatic components to volatilize as an aerosol together with the aerosol former. .

[0127] As a result, it is possible to efficiently volatilize the aromatic components of the aromatic source material. Therefore, when the user inhales the aerosol emitted from the aromatic cartridge 100 immediately after the end of the temperature rise process of the heated tobacco, the user can enjoy the aroma more fully.

[0128] The hot-melt material may be added to the raw material (B). FIG. 7 shows another embodiment of the manufacturing process. As shown in FIG. 7, when adding the hot-melt material to the raw material (B), for example, it may be added to the raw material (B1).

[0129] As described above, according to the aromatic cartridge 100 of the present invention, it is possible to reduce the ventilation resistance in the axial direction of the cover 10. Therefore, it is possible to improve the ease of sucking the aerosol generated from the aromatic substrate 20. In addition, since the aerosol and air can be mixed in an appropriate distribution,

[0130] [Embodiment 2] The aromatic cartridge 100 of Embodiment 2 is different from the aromatic cartridge 100 of Embodiment 1 in that a regulating member for regulating the axial movement of the cover 10 of the aromatic substrate 20 is used. For the same components as those of the aromatic cartridge 100 of Embodiment 1, the same reference numerals are given to the same

[0131] locations and the description thereof is omitted. As shown in FIG. 8, the regulating member 60 is provided in contact with the aromatic substrate 20 arranged at the most proximal side of the cover 10 among the two aromatic substrates 20.

The ventilation passage 61 is defined by four concave grooves formed at equal intervals in the circumferential direction and along the axial direction on the outer peripheral surface of the regulating member 60 and the inner peripheral surface of the cover 10

[0133] Further, the ventilation passage 61 may be composed of one or a plurality of through-holes formed so as to axially penetrate from one end face to the other end face of the restricting member 60, for example. The ventilation passage 61 may be, for example, a central ventilation passage formed along the axis of the restricting member 60 and a plurality of ventilation passages 41 arranged side by side in the circumferential direction so as to surround the central ventilation passage and also formed so as to axially penetrate. Further, the restricting member 60 may be composed of a honeycomb structure or the like having a plurality of ventilation passages with a hexagonal end face shape of the partition wall and axially penetrating. Further, the restricting member 60 may be composed of a porous body in which continuous air bubbles are formed, for example. The restricting member 60 preferably has a shape capable of restricting the axial movement of the cover 10 of the aromatic base material 20 when the electric heating means of the heated tobacco is inserted at one or both end faces in the axial direction of the cover 10, preferably at the end face arranged on the aromatic base material 20 side. Here, the shape capable of restricting the axial movement of the aromatic base material 20 in the cover 10 may be, for example, a shape capable of restricting the movement of the material of the aromatic base material 20 to such an extent that there is no practical problem. By forming the restricting member 60 in this way, the restricting member 60 restricts the movement of the aromatic base material 20 to the other end side. In other words, the restricting member 60 can support the aromatic base material 20. Further, the restricting member 60 can cool the high-temperature aerosol when the aerosol containing the aromatic component generated from the aromatic base material 20 passes through. For this reason, the restricting member 60

[0134] Further, the ventilation passage 61 may be composed of one or a plurality of through-holes formed so as to axially penetrate from one end face to the other end face of the restricting member 60, for example. The ventilation passage 61 may be, for example, a central ventilation passage formed along the axis of the restricting member 60 and a plurality of ventilation passages 41 arranged side by side in the circumferential direction so as to surround the central ventilation passage and also formed so as to axially penetrate.

The restricting member 60 preferably has a shape capable of restricting the axial movement of the cover 10 of the aromatic base material 20 when the electric heating means of the heated tobacco is inserted at one or both end faces in the axial direction of the cover 10, preferably at the end face arranged on the aromatic base material 20 side. Here, the shape capable of restricting the axial movement of the aromatic base material 20 in the cover 10 may be, for example, a shape capable of restricting the movement of the material of the aromatic base material 20 to such an extent that there is no practical problem.

[0135] The restricting member 60 preferably has a shape capable of restricting the axial movement of the cover 10 of the aromatic base material 20 when the electric heating means of the heated tobacco is inserted at one or both end faces in the axial direction of the cover 10, preferably at the end face arranged on the aromatic base material 20 side.

For this reason, the restricting member 60 Further, the ventilation passage 61 may be composed of one or a plurality of through-holes formed so as to axially penetrate from one end face to the other end face of the restricting member 60, for example. The ventilation passage 61 may be, for example, a central ventilation passage formed along the axis of the restricting member 60 and a plurality of ventilation passages 41 arranged side by side in the circumferential direction so as to surround the central ventilation passage and also formed so as to axially penetrate. Further, the restricting member 60 may be composed of a honeycomb structure or the like having a plurality of ventilation passages with a hexagonal end face shape of the partition wall and axially penetrating. Further, the restricting member 60 may be composed of a porous body in which continuous air bubbles are formed, for example.

[0136] By forming the restricting member 60 in this way, the restricting member 60 restricts the movement of the aromatic base material 20 to the other end side. In other words, the restricting member 60 can support the aromatic base material 20. Further, the restricting member 60 can cool the high-temperature aerosol when the aerosol containing the aromatic component generated from the aromatic base material 20 passes through. For this reason, the restricting member 60 Further, the ventilation passage 61 may be composed of one or a plurality of through-holes formed so as to axially penetrate from one end face to the other end face of the restricting member 60, for example.

For example, polyolefin -based resin, polyester-based resin, polystyrene-based resin, nylon-based resin, acrylic-based resin -based resin, silicone-based resin, fluorine-based resin, polyurethane-based resin, ethylene-vinyl acetate (EVA) -based resin, phenol-based resin, amino-based resin, ABS-based resin, and biodegradable plastic -based resin, etc. are mentioned. Among these resins, since the aromatic cartridge 100 becomes waste after use, biodegradable plastic is preferable from the viewpoint of natural environment protection.

[0140] Examples of biodegradable plastics include poly(3-hydroxybutyrate) (PHB) ), poly(ε-caprolactone) (PCL), poly(butylene succinate) (PBS), and polylactic acid (PLA), etc.

[0141] According to such an aspect, it becomes possible to hold the aromatic base material 20 arranged on the most proximal end side of the cover 10 at a predetermined position within the cover 10 by the restricting member 60. As a result, when the aromatic cartridge 100 is attached to the heated tobacco 50, by the electric heating means 52 When the aromatic cartridge 100 is attached to the heated tobacco 50, by the electric heating means 52 The fragrance base material 20 can be held at a position suitable for heating.

The partition wall 42 is, for example, heated It has heat resistance corresponding to the temperature range (for example, 180 to 400 ° C) heated by the electric heating means of the formula tobacco, and fibers (either natural fibers or synthetic fibers may be used) are intertwined with each other to form a lump. The partition wall 42 has an air permeability resistance at least comparable to that of the filter 30 in the axial direction of the cover 10.

[0149] Note that the form of the partition wall is not limited to such a form. For example, as shown in FIG. 11, two disk-shaped partition walls 43 may be used. Each of the partition walls 43 has a through hole 44 formed in the thickness direction at its center. Each of the partition walls 43 can be fixed to the wrapper 11 with, for example, an adhesive or the like.
