Description

[Technical Field]

[0001] The present invention relates to an aroma cartridge that is attached to an inhalation device having an electric heating means and that is capable of generating an aerosol containing an aromatic component by being heated by the electric heating means. [Background technology]

[0002] The aroma cartridge is attached to an inhalation device having an electric heating means, and generates an aerosol containing an aromatic component by being heated by the electric heating means.

[0003] Patent Document 1 discloses such an aroma cartridge and a smoking device that is electrically heated by a set of electric heating elements to generate tobacco flavor or other components in the form of vapor or aerosol and deliver them to the smoker. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 07-184627 Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, aroma cartridges can take various forms depending on the specifications of the inhalation device. For example, aroma cartridges are often formed in a cylindrical shape, but in inhalation devices in which the electric heating means is formed in a blade or 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 when heated.

[0006] In contrast, in an inhalation device in which the electrical heating means is formed in a cylindrical shape or the like so that it can heat the outer surface of the fragrance cartridge, there is no need to insert the electrical heating means into the fragrance base material, so the diameter of the electrical heating means can be set smaller than that of the fragrance cartridge used in an inhalation device which is formed in a blade shape or the like.

[0007] Users desire that the smoking sensation and smoking time be consistent regardless of the form of the aroma cartridge, and therefore it is preferable that the amount of aroma base material that generates the aerosol filled in the aroma cartridge be at least a certain amount regardless of the form of the aroma cartridge.

[0008] When the axial length of the aroma base material filled in the aroma cartridge becomes long, the airflow resistance in the aerosol flow path increases, making it difficult to obtain a sufficient amount of aerosol suitable for smoking.

[0009] Furthermore, if the amount of fragrance base material is reduced in order to reduce the airflow resistance in the aerosol flow path, there is a risk that the fragrance base material will move to one end or the other end of the cartridge. If the fragrance base material moves to such a position, when the fragrance cartridge is attached to an inhalation device, the fragrance base material will not be positioned in an area that can be heated by the electrical heating means of the inhalation device (heating area), which will result in the inability to generate aerosol properly.

[0010] The present invention has been made in consideration of the above problems, and aims to provide an aroma cartridge that has breathability suitable for smoking and is capable of generating sufficient aerosol, regardless of the shape of the aroma cartridge. [Means for solving the problem]

[0011] The fragrance cartridge of the present invention is an fragrance cartridge that is attached to an inhalation device having an electric heating means and generates an aerosol when heated by the electric heating means, and is characterized in that it has a cylindrical cover and an aroma base material that is contained in the cover and generates an aerosol containing an aromatic component when heated, and the aroma base material is provided at multiple locations at predetermined intervals in the axial direction of the cover.

[0012] According to the fragrance cartridge of the present invention, the fragrant substrate is provided at multiple locations at predetermined intervals in the axial direction of the cover. This allows the fragrant substrate to be distributed throughout the heating region, even when the heating region of the inhalation device is long in the axial direction, thereby enabling heat from the heating region to be evenly transferred to the fragrant substrate. In other words, the airflow resistance caused by the fragrant substrate in the axial direction of the cover can be reduced according to the spacing, compared to when the fragrant substrate is distributed throughout the entire heating region. Furthermore, by disposing the fragrant substrate intermittently in the axial direction of the cover, regions with low airflow resistance and regions with high airflow resistance can be alternately arranged. Therefore, even if the flow rate of the aerosol-containing gas is slowed in regions with high airflow resistance, it is increased in the subsequent regions with low airflow resistance. As a result, the airflow resistance in the axial direction of the cover can be reduced compared to when the fragrant substrate is disposed all at once. This allows for improved inhalation of the aerosol generated from the fragrant substrate. Furthermore, the aerosol and air can be mixed in an appropriate proportion, thereby improving the flavor.

[0013] In the fragrance cartridge of the present invention, it is preferable that the cover has one or more partition walls between two of the fragrance substrates arranged close to each other, and that the partition walls are breathable in the axial direction of the cover.

[0014] According to this embodiment, by disposing a partition between the two fragrant substrates, it is possible to prevent the fragrant substrate disposed on the distal end side of the cover from moving toward the proximal end side of the cover, and the fragrant substrate disposed on the proximal end side of the cover from moving toward the distal end side of the cover, and it is possible to define the gap between the two fragrant substrates in the axial direction of the cover by the partition. Furthermore, because the partition is breathable in the axial direction of the cover, it is possible to ensure breathability at this predetermined gap.

[0015] In the fragrance cartridge of the present invention, the fragrance base material is preferably in a granular form, and has a lid material that closes the tip side of the cover and is breathable in the axial direction of the cover.

[0016] According to this aspect, it is possible to prevent the fragrant base material from leaking out to the outside through the opening formed on the tip side of the cover.

[0017] In the fragrance cartridge of the present invention, a regulating member is provided that is adjacent to the fragrance substrate that is arranged closest to the base end of the cover among the multiple fragrance substrates and that regulates the movement of the fragrance substrate toward the base end of the cover, and it is preferable that the regulating member is breathable in the axial direction of the cover.

[0018] According to this aspect, the restricting member can hold the fragrance substrate disposed closest to the base end of the cover in a predetermined position within the cover, thereby holding the fragrance substrate in a position suitable for heating by the electric heating means when the fragrance cartridge is attached to the inhaler.

[0019] In the fragrance cartridge of the present invention, the partition is preferably made of at least one material selected from a cotton-like material, a porous material, a honeycomb structure, a mesh structure, and a paper wrapping material having a through hole formed penetrating from one end to the other along the axial direction of the cover.

[0020] In the aroma cartridge of the present invention, the aroma base material is preferably dispersed and arranged within the heating region of the electric heating means when the aroma cartridge is attached to the inhalation tool.

[0021] By distributing the fragrance substrates so that they are dispersed within the heating area of ​​the electric heating means when the fragrance cartridge is attached to the inhalation device, the heat generated by the electric heating means can be efficiently transferred to each fragrance substrate, thereby enabling aerosol to be generated in a balanced manner from each fragrance substrate. [Effects of the Invention]

[0022] The aroma cartridge of the present invention can reduce the airflow resistance in the axial direction of the cover, thereby improving the ease of inhaling the aerosol generated from the aroma base material. Furthermore, the aerosol and air can be mixed in an appropriate ratio, improving the flavor. [Brief explanation of the drawings]

[0024] [Embodiment 1] Hereinafter, one embodiment of the aroma cartridge according to the present invention will be described with reference to the drawings. Fig. 1 is a perspective view of the aroma cartridge according to this embodiment. Fig. 2 is an exploded perspective view of the aroma cartridge. Fig. 3 is a cross-sectional view of the aroma cartridge of Fig. 1. Fig. 4 is an explanatory view showing the aroma cartridge according to this embodiment when attached to an inhaler.

[0025] [Configuration of the aroma cartridge 100] 1 and 2, the aroma cartridge 100 can be used, for example, in a cartridge for a heated tobacco product. Hereinafter, an example will be described in which the aroma cartridge 100 is a cartridge used in a heated tobacco product, which is an inhalation device having an electric heating means.

[0026] The aroma cartridge 100 comprises a cylindrical cover 10, an aroma base material 20 housed in one end of the cover 10, and a filter 30 housed in the other end of the cover 10. In this embodiment, the aroma base material 20 is provided in two locations at a predetermined distance in the axial direction of the cover 10. A partition wall 40 is provided between the aroma base materials 20.

[0027] The cover 10 is composed of a cigarette paper 11 that covers the aroma base material 20, and a tipping paper 12 that further covers the outer peripheral portion of the filter 30 from the outside of the cigarette paper 11. The cigarette paper 11 is joined to the tipping paper 12 by means of adhesion, heat fusion, or the like.

[0028] The cigarette paper 11 and the tipping paper 12 can be made of, for example, paper, synthetic resin film, metal foil, etc., or may be a composite sheet formed by laminating these. Furthermore, an adhesive or fusible layer such as an adhesive layer or a hot melt layer may be formed on the inner surface of the cigarette paper 11 and the tipping paper 12.

[0029] In this embodiment, the cigarette paper 11 serves to gather the aroma base material 20 together to form a columnar shape. The cigarette paper 11 serves to connect the aroma base material 20, the partition wall 40, and the filter 30. The tipping paper 12 serves to reinforce the part (mouthpiece) that the user holds in the mouth of the aroma cartridge 100. Note that the cover 10 is not limited to one in which the cigarette paper 11 and the tipping paper 12 are separately formed, and may be, for example, formed from a single sheet in which the cigarette paper 11 and the tipping paper 12 are integrated.

[0030] 2 and 3, in this embodiment, the two fragrant substrates 20, the partition wall 40, and the filter 30 are arranged along the axial direction from one end to the other end of the cover 10. The space surrounded by the inner wall of the cover 10 serves as a flow path for the aerosol.

[0031] The fragrance substrate 20 may be, for example, a collection of rod-shaped, strip-shaped, powder-shaped, granular, pellet-shaped, small piece-shaped, sheet-shaped, fibrous, porous, paste-shaped, or block-shaped components. In this embodiment, fragrant base material 20 is formed into a cylindrical shape as a whole by strip-shaped components. Note that fragrant base material 20 must have a moderate level of breathability, which is achieved by gaps between the packed components, gaps caused by cracks formed by drying of the packed components, and the porous structure of the components themselves.

[0032] The aroma base material 20 can generate an aerosol containing aroma components by being heated by the electrical heating means of a heated tobacco product, which is an inhalation device. The aroma base material 20 is preferably a material containing a ground and dried plant material, not limited to tobacco plants, but also non-tobacco plants, an aerosol former capable of generating an aerosol, and a thermofusible substance that melts when heated. The composition of the aroma base material 20 will be described later.

[0033] In this embodiment, two fragrant base materials 20 are arranged at a predetermined distance from each other, but the number of fragrant base materials 20 is not limited, and three or more fragrant base materials may be arranged at a predetermined distance from each other.

[0034] The filter 30 preferably has a certain degree of breathability to the mainstream smoke or aerosol generated from the aromatic base material 20, and has the function of capturing solid particles contained in the mainstream smoke or aerosol and adsorbing harmful components, etc. The shape of the filter 30 is not particularly limited as long as it can be wrapped in the cover 10.

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

[0036] 2 and 3, the partitions 40 are disposed adjacent to each of the two scented substrates 20. The partitions 40 may have an outer peripheral surface that corresponds to the shape of the inner peripheral surface of the cover 10. In this embodiment, the partitions 40 are formed into a cylindrical shape as a whole. The partitions 40 are fixed to the cover 10 by a fixing means such as adhesion or welding, and in this embodiment, they are fixed to the inner peripheral surface of the cigarette paper 11.

[0037] The partition 40 is disposed between two aromatic substrates 20 disposed adjacent to each other within the cover 10. The partition 40 is breathable in the axial direction of the cover 10. The partition 40 may have breathability suitable for smoking, and may have breathability at least as good as that of the filter 30, for example.

[0038] In this embodiment, the partition 40 is formed in a hollow cylindrical shape with a through-hole 41 formed from one end to the other, but it may also be composed of a columnar member without a through-hole 41. The partition 40 is preferably made of a material that is heat-resistant to the temperature range (e.g., 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. The partition 40 may be, for example, a paper cigarette member formed by rolling a sheet of paper into a spiral shape from one end, thereby forming a cylindrical shape with a spiral-shaped gap when viewed from the end surface.

[0039] The shape of the partition 40 is not limited as long as it has a structure that allows air to pass from the distal end to the proximal end of the cover 10 and has the function of restricting movement of the fragrant substrate 20 disposed on the distal end toward the proximal end. The partition 40 is preferably made of at least one material selected from, for example, a cotton-like material, a porous material, a honeycomb structure, a mesh structure, and the aforementioned paper wrapping material. It is not necessary to provide the partition 40 in the fragrance cartridge 100, as long as the fragrant substrates 20 are disposed at predetermined intervals in the axial direction of the cover 10. For example, the partition 40 is not necessarily required as long as the fragrant substrates 20 can be fixed to the inner surface of the cover 10 using the adhesive properties of the material itself or an adhesive.

[0040] As shown in Fig. 4, the heated tobacco product 50 has an insertion hole 51 formed so that the aroma cartridge 100 can be inserted therein. An electric heating means 52 capable of raising the temperature of the inner circumferential surface of the insertion hole 51 is provided inside the heated tobacco product 50.

[0041] The electrical heating means 52 includes, for example, an electrically resistive material, and when powered, can be heated to 150 to 400° C. Electrically resistive materials 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 and metallic materials.

[0042] The electrically resistive material may be embedded in, encapsulated in, or coated with an insulating material in the composite, or vice versa. As an alternative to an electrically resistive material, the electrical heating means 52 may 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 heated region R1, and the other region is defined as a non-heated region R2.

[0044] The aroma cartridge 100 is attached to the heated tobacco product 50 by being inserted into the insertion hole 51 of the heated tobacco product 50. When the aroma cartridge 100 is attached to the heated tobacco product 50, the entire aroma base material 20 is disposed in the heating region R1 of the insertion hole 51.

[0045] In this way, by distributing each of the fragrant substrates 20 in the heating region R1 of the heated tobacco product 50, heat from the electric heating means 52 is efficiently transferred to each of the fragrant substrates 20, making it possible to generate an amount of aerosol suitable for smoking. Furthermore, by disposing the highly breathable partition walls 40 between the fragrant substrates 20, it is possible to set the airflow resistance within an appropriate range.

[0046] [Configuration of fragrance base material 20] The fragrance base material 20 includes a ground and dried plant material that generates a fragrance when heated, and an aerosol former that generates an aerosol when heated. Therefore, the fragrance base material 20 can generate an aerosol containing the fragrance components when heated. The fragrance base material 20 preferably contains at least one of a heat-melting substance that melts when heated, catechin, cross-linked polyvinylpyrrolidone and / or polyvinylpyrrolidone, and a fragrance.

[0047] In addition to the above, the fragrance base material 20 may also contain, for example, a fragrance that can supplement the fragrance emitted from the crushed and dried plant material, a molding agent that can improve the moldability of the fragrance base material 20, a binder that contributes to binding and integrating the aerosol former and the crushed and dried plant material, a sorbent that can retain the fragrance in the fragrance base material 20, and a preservative that can improve the shelf life of the fragrance base material 20.

[0048] (ground dried plant material) Examples of ground and dried plant materials include tobacco leaves and stems, as well as leaves, stems, flowers, seeds, fruits, bark, roots, and the like of non-tobacco plants.

[0049] The crushed and dried plant materials include, in particular, Chinese tea, black tea, roses, plants of the Oleaceae family, lavender, saffron flowers, shallots, garlic, onions, the rhizomes of konjac, Chinese quince, plants of the Rutaceae family (bitter orange, satsuma mandarin, summer orange, ponkan, hassaku citrus, iyokan, ichan lemon, trifoliate orange, orange, mandarin orange, kabosu, Kishu mandarin, quinot, grapefruit, koji, sanbokan, citron, jabara, sudachi, tachibana, tangor, summer mandarin, hanayuzu, hyuganatsu, Hirami lemon (shikwasa), pomelo (citron), yuzu, lime, lemon, kaffir lime, etc.), plants of the Rosaceae family, peach, apple, pineapple, mango, kiwi, etc. Suitable ingredients for providing a pleasant aroma to the user include, but are not limited to, at least one selected from among orange, melon, pomegranate, plum, apricot, blueberry, plants of the genus Fragaria (Rosaceae), raspberry, banana, and grape fruit, peppermint plants of the genus Mentha (Lamiaceae) (peppermint, Japanese mint, apple mint, water mint, Corsican mint, pennyroyal mint, etc.), spearmint plants of the genus Mentha (Lamiaceae) (spearmint, horse mint, green mentha, chili mint, ginger mint, etc.), catnip, lemon balm, savory, willow mint (hyssop), and the aboveground stems and leaves of plants of the genus Nicotiana (Solanaceae).

[0050] It is preferable that the crushed and dried plant material has three elements: fragrance, which is defined as the scent that wafts from the aroma cartridge 100 itself; aroma, which is defined as the scent that wafts into the air when the aroma cartridge 100 is heated; and flavor, which is defined as the scent that wafts into the mouth when the aroma cartridge 100 is heated and inhaled together with the aerosol.

[0051] The dried, crushed plant material (hereinafter also referred to as fragrance material) that constitutes the fragrance preferably contains at least one selected from Chinese tea, black tea, rose, plants of the Oleaceae family, Osmanthus species, lavender, saffron flowers, and above-ground stems and leaves of plants of the Solanaceae family, Nicotiana species.

[0052] The crushed and dried plant material that constitutes the aroma (hereinafter also referred to as aroma material) preferably contains at least one selected from the rhizomes of scallions, shallots, garlic, onions, and konjac, and the above-ground stems and leaves of plants of the Nicotiana species of the Solanaceae family.

[0053] The ground and dried plants that make up the flavor (hereinafter also referred to as flavor materials) include quince, plants of the genus Citrus in the family Rutaceae (bitter orange, satsuma mandarin, summer orange, ponkan, hassaku, iyokan, ichan lemon, trifoliate orange, orange, mandarin orange, kabosu, Kishu mandarin, quinot, grapefruit, koji, sanbokan, citron, jabara, sudachi, tachibana, tangor, summer mandarin, hanayuzu, hyuganatsu, Hirami lemon (shikwasa), pomelo (citron), yuzu, lime, lemon, kaffir lime, etc.), plants of the genus Peach in the family Rosaceae, apple, pineapple, mango, kumquat, melon, etc. It is preferable that the above-ground stems and leaves of the following plants are selected from the group consisting of rye, pomegranate, plum, apricot, blueberry, plants of the genus Fragaria in the family Rosaceae, raspberry, banana, grape fruit, peppermint plants of the genus Mentha in the family Lamiaceae (peppermint, Japanese mint, apple mint, water mint, Corsican mint, pennyroyal mint, etc.), spearmint plants of the genus Mentha in the family Lamiaceae (spearmint, horse mint, green mentha, chili mint, ginger mint, etc.), catnip, lemon balm, brugman (savory), willow mint (hyssop), and Nicotiana species in the genus Nicotiana in the family Solanaceae.

[0054] (Aerosol former) The aerosol former is added to generate an aerosol when the fragrance base material 20 is heated. Examples of aerosol formers that can be used include glycerin, propylene glycol, sorbitol, triethylene glycol, lactic acid, diacetin (glycerin diacetate), triacetin (glycerin triacetate), triethylene glycol diacetate, triethyl citrate, isopropyl myristate, methyl stearate, dimethyl dodecanedionate, and dimethyl tetradecanedione, with glycerin and propylene glycol being particularly preferred.

[0055] (thermally melting substances) The heat-melting substance is added to melt at a relatively low temperature, dissolving and vaporizing the fragrant components generated from the fragrance base material 20, so that they can be easily emitted together with the aerosol former. The heat-melting substance also serves to fix the fragrant source material and / or the fragrant agent at room temperature.

[0056] The melting point of the heat-fusible substance is 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 heat-fusible substance is less than 50°C, the heat-fusible substance may melt during hot periods such as summer, causing stickiness. If the melting point of the heat-fusible substance is more than 100°C, the heat-fusible substance may not melt sufficiently in the early stages of the aroma base heating process, and the aroma of the aerosol may tend to be insufficient immediately after the heating process of the heated tobacco is completed.

[0057] The melting point of a heat-melting substance can be measured, for example, in accordance with the paraffin wax melting point measurement method specified in JIS K 2235. That is, using a specified melting point tester, a molten sample is placed in a test tube, the readings on the melting point measurement thermometer are read every 15 seconds, and the temperature at which the temperature drop is within a certain range (a difference of 0.1°C or less for five consecutive readings) can be measured as the melting point.

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

[0059] If the average particle size of the thermally melting substance is too large, the total surface area of ​​the substance will be small, reducing the chance of contact with the heat source. As a result, the thermally melting substance will not be melted sufficiently, and the concentration of the aromatic component in the aerosol immediately after the temperature rise process will tend to be reduced.

[0060] If the outer diameter of the thermally fusible substance is too small, it becomes difficult to form an island-sea structure in which the thermally fusible substance is dispersed in the fragrance base material 20, as described below. As a result, each of the thermally fusible substances exists in the fragrance base material 20 as aggregated masses, which creates regions where the melting rate upon contact with the heat source decreases, and the concentration of the fragrance components in the aerosol immediately after the temperature rise process tends to decrease. The thermally fusible substance is preferably contained in the fragrance 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] In order to balance the volatilization amounts of the smoke components and the aromatic components, the blend amounts of the fragrance source material, the aerosol former, and the thermally 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.

[0062] The heat-melting substance is not particularly limited as long as it is an "organic compound that exhibits a melting point or softening point and becomes a non-Newtonian fluid when heated." The heat-melting substance is preferably an organic compound generally known as wax, and typical examples of wax include petroleum-based natural waxes, synthetic waxes, plant-based natural waxes, and animal-based natural waxes. Various tackifiers, including rosin, which is also used as wax, can also be used. These can be used alone or as a mixture containing at least one selected from these.

[0063] As the heat-melting substance, natural plant wax or Natural animal waxes are preferably used. Natural plant waxes include, for example, wax and lacquer wax. Carnauba wax, sugarcane wax, palm wax, candelilla wax, etc. can be used. In addition, natural animal waxes such as beeswax, spermaceti, privet wax, wool wax, and shellac can be used. These can be easily obtained with a melting point in the range of 50 to 100°C as specified in the present invention. In addition, since it has a pleasant flavor, it can enhance the aroma of the aerosol. Among these natural waxes, carnauba wax, beeswax, petrolatum, and paraffin wax are particularly Beeswax, which has a melting point of 62 to 65°C and is rich in aromatic components, is most preferred.

[0064] Natural plant waxes and natural animal waxes are mainly composed of esters of fatty acids and fatty alcohols. Natural plant waxes and natural animal waxes are made up of fatty acids with various carbon numbers and fatty alcohols. It is a mixture of esters, and also contains free fatty acids, free fatty alcohols, and hydrocarbons. Therefore, natural plant waxes and natural animal waxes have a wide molecular weight distribution and a wide melting point. It has a wide viscosity range and is characterized by high viscosity when melted.

[0065] Petroleum-based natural waxes are hydrocarbon compounds, so they contain aromatic components and aerosol formers. It has the advantage of having little interaction with other ingredients and less of an adverse effect on flavor. Examples of waxes include petrolatum, paraffin wax, and microcrystalline wax. Preferably, scouring powder or the like can be used.

[0066] These petroleum-based natural waxes have different melting points depending on their molecular structure. is a mixture of branched hydrocarbons and alicyclic hydrocarbons, and its melting point ranges from 36 to 60°C. It is spacious. Paraffin wax is mainly composed of straight-chain 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. Although it has low crystallinity, it has a high molecular weight and exhibits the highest melting point of 60 to 90°C. The melting point range is also the second widest after Vaseline.

[0068] These petroleum-based natural waxes are all hydrocarbon compounds extracted from crude oil. Paraffin wax and microcrystalline wax have different melting viscosities and surface roughness when melted. It has low surface energy and also has little interaction with fragrance components and aerosol formers.

[0069] As such 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. For example, high-purity refined paraffin wax, a special product manufactured by Nippon Seiro Co., Ltd. HNP series products for specific applications, SP series products for specific applications, and isoparaffin produced using special manufacturing methods are available. The main component, EMW series products, are also preferably used. Microcrystalline wax is also For example, any of the Hi-Mic series manufactured by Nippon Seiro Co., Ltd. is preferably used.

[0070] Synthetic waxes include, for example, Fischer-Tropsch waxes. psch) wax, polyethylene (PE) wax, modified PE wax, polypropylene Polypropylene (PP) wax, modified PP wax, fatty acid amide, fatty acid, fatty alcohol, polypropylene Polyoxyalkylene glycol, polyoxyethylene alkyl ether, polyoxyethylene Preferably, phenyl alkylamines and the like can be used.

[0071] In particular, Fischer-Tropsch wax is a linear hydrocarbon-based organic compound, It has low melt viscosity and surface energy when melted by heat, and is compatible with aerosol formers and aromatic ingredients. The interaction is also small. As for Fischer-Tropsch wax, medium melting point product C80 etc. Temperature: about 85 to 88°C) can be used.

[0072] In addition, PE wax and modified PE wax, and PP wax and modified PP wax Also, coke is a hydrocarbon compound and can be preferably used. "Hiwax (registered trademark)" manufactured by Sanyo Chemical Industries, Ltd. "Sunwax" manufactured by Sanyo Chemical Industries, Ltd.

[0089] (sorbent) In the present invention, the temperature of the fragrance substrate 20 is set to an optimum temperature at which the aerosol former and the fragrance source material volatilize. If an absorbent is used to prevent fresheners and fragrances from evaporating before the temperature reaches the As described above, the sorbent is used to add a fragrance such as a cooling agent or a perfume to the heated aroma-generating material 20. It can be kept overnight.

[0090] In one preferred embodiment of the sorbent, the compound is adsorbed to the aroma-generating substrate 2. For example, if the compound is menthol, In this case, menthol has a phenolic hydroxyl group. For example, cross-linked polyvinylpyrrolidone (PVPP) is capable of adsorbing hydroxyl groups. Polyvinylpolypyrrolidone), Polyvinylpyrrolidone (PVP) Hydrophilic cross-linked polymers such as the above can be used.

[0091] Also, for example, when the compound is nicotine, nicotine is a five-membered heterocycle containing nitrogen. Therefore, as a sorbent, it is compatible with five-membered heterocyclic compounds containing nitrogen. Crosslinked PVP may be used, which is believed to form the effect.

[0092] When crosslinked PVP and / or PVP is used as the sorbent, the sorbent is a source of fragrance, aerosol It is preferable that the content is 4 to 25 mass% relative to 100 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 %.

[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 using a laser diffraction particle size distribution analyzer. 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 there is any, the effect of suppressing the shrinkage of the fragrance base material 20 tends to be poor. If the mass average molecular weight (Mw) exceeds 60,000, the aromatic base material 20 becomes prone to breakage. There is a tendency.

[0106] The binder accounts for 100% by mass of the total amount of the fragrance source material, aerosol former, and thermal melting substance. The content is preferably 5 to 30 mass %, and more preferably 8 to 28 mass %. It is more preferable that the binder is contained in the fragrance base material 20 at such a content. This can improve the strength and moldability of the fragrance substrate 20, and the fragrance source material and aerosol It is possible to avoid adverse effects such as the generation of volatile matter from the former.

[0107] In addition, the fragrance base material 20 of the present invention contains both a binder and a molding agent. In this case, the blending ratio of the binder to the molding agent is preferably 1:1 to 1:25 by mass. This is preferable in terms of the bonding effect.

[0108] (preservative) To preserve the heated aroma-emitting cartridge for a long period of time, a preservative may be used.

[0109] Next, a method for producing the fragrant base material 20 will be described. As shown in FIG. 5, the dried and crushed plant material that constitutes the fragrance is used. and flavor materials, which are crushed and dried plants that make up the flavor. Raw material (A) and raw material (B) containing aromatic materials, which are crushed and dried plants that make up aromas. A mixing step is performed. The mixing step is performed below the melting point of the heat-melting substance. This can be done using, for example, a known mixer.

[0110] Raw material (A) contains fragrance materials, which are crushed and dried plants that make up the fragrance. The raw material (A1) is a ground and dried plant material that constitutes the flavor, and a heat-melting A raw material containing the substance (A2), an alcohol-water solution of microcrystalline cellulose, and an alcohol-based binder. A raw material (A3) containing an aqueous alcohol solution of a sorbent and an aerosol former A raw material (A4) containing a fragrance and a molding agent is mixed and aged to obtain .

[0111] The raw materials (A1) to (A4) are mixed at a temperature below the melting point of the heat-melting substance. This mixing step can be carried out using, for example, a known mixer.

[0112] The raw material (A1) is obtained by sterilizing a fragrance material and then pulverizing it.

[0113] The raw material (A2) is a mixture of flavoring material and heat-melting material, which is sterilized and then crushed. Specifically, as shown in FIG. 6, after sterilizing the flavoring material, the flavoring material is cut into pieces of a predetermined size. The powdered heat-fusible substance is heated and mixed at a temperature above the melting point of the heat-fusible substance. After cooling, the mixture is crushed to a predetermined size. The raw material (A2) is preferably prepared by compressing and shearing the mixture, cooling it, and then pulverizing it. stomach.

[0114] The raw material (A3) is an alcoholic solution of microcrystalline cellulose, an alcoholic solution of a binder, and and sorbent (crosslinked polyvinylpyrrolidone and / or polyvinylpyrrolidone) in alcohol water The alcohol solution is obtained by mixing the solutions. The 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 molding agent. do.

[0116] The aging is preferably carried out, for example, at a temperature of 15 to 30°C for 3 to 14 days. From the viewpoint of preserving the aroma components, it is recommended to keep the temperature at 20±2℃ for 4 to 7 days. If the temperature exceeds 30°C or the aging period exceeds 14 days, mold may grow and There is a tendency for corruption to increase.

[0117] The raw material (B) is a raw material containing aromatic materials, which are crushed and dried plants that make up the aroma. It is obtained by mixing raw material (B1) and raw material (B2) containing a preservative. The mixing of (B1) and (B2) can be carried out using, for example, a known mixer.

[0118] The raw material (B1) is obtained by sterilizing an aromatic material and then crushing it. The raw material (B2) is obtained by dissolving a preservative in pure water.

[0119] By carrying out the mixing step of mixing the raw materials (A) and (B) in this manner, the aromatic The fragrance base material 20 is formed into a sea-island structure in which the powder of the heat-melting substance mixed with the fragrance source material is dispersed. can be done.

[0120] Next, the mixture obtained in the mixing step is compressed and sheared to form it into a sheet. Compression and shear processing can be performed using, for example, three rolls. By compressing and shearing with three rolls, air is trapped and water is prevented from evaporating. It can be formed into a sheet.

[0121] The sheet obtained in this way has a porous structure containing air inside. As a result, it is possible to obtain a low-density fragrance substrate 20. The roll has an extremely flat surface, so the surface of the sheet is formed flat.

[0122] That is, the aromatic base material 20 is formed into a porous material containing air therein by the compression and shear processing. Because of the structure, it has low density and its surface is flat and smooth. .

[0123] The mixture formed into a sheet by compression and shear processing is cut into a desired shape and size. The sheet-like mixture is then cut into strips, for example.

[0124] In this way, the mixing process, compression / shearing process, and cutting process are carried out below the melting point of the heat-melting substance. By using the heat-melting substance, the melting of the heat-melting substance is prevented from spreading throughout the fragrance base material 20, and the fragrance It is possible to maintain the sea-island structure of the thermally fusible substance in the substrate 20.

[0125] The fragrance base material 20 has a sea-island structure in which powder of the heat-melting substance mixed with the fragrance source material is dispersed. When this is done, the heat-melting substance is dispersed in the aroma base material 20 in the form of islands.

[0126] The heat-melting substance is dispersed in the fragrance base material 20 in the form of islands, rather than being impregnated in the fragrance source material. The dispersed arrangement allows the material to flow more easily when melted, and the aromatic components released from the aromatic source material In addition, the flowing thermally fused substance comes into contact with the aerosol former, and the aromatic The fragrance ingredients can be easily volatilized by forming an aerosol together with the aerosol former. .

[0127] As a result, the aromatic components of the aromatic source material can be efficiently volatilized. The laser was generated by the aroma cartridge 100 immediately after the heating process of the heated tobacco product was completed. When the aerosol is inhaled, the aroma can be enjoyed more fully.

[0128] The heat-melting substance may be added to the raw material (B). Another embodiment of the manufacturing process is shown in Figure 7. When the substance is added to the raw material (B), it may be added to the raw material (B1), for example.

[0129] As described above, according to the aroma cartridge 100 of the present invention, the cover 10 has a axial direction. Therefore, it is possible to reduce the airflow resistance generated by the aromatic base material 20. It is possible to improve the ease of inhaling the sol. In addition, it is possible to properly distribute the aerosol and air. Since the mixture can be mixed in a single step, it is possible to improve the flavor.

[0130] [Embodiment 2] The fragrance cartridge 100 of the second embodiment is configured to move the cover 10 of the fragrance substrate 20 in the axial direction. The aroma cartridge 100 of the first embodiment differs from the aroma cartridge 100 of the first embodiment in that a restricting member is used. The same components as those of the aroma cartridge 100 of the first embodiment are denoted by the same reference numerals. The explanation will be omitted.

[0131] As shown in FIG. 8, the restricting member 60 is positioned on the most base of the two fragrant base materials 20 of the cover 10. The restricting member 60 is provided in contact with the fragrant base material 20 disposed on the end side. In this case, the air conditioner is formed in a substantially cylindrical shape and has one or more air passages 61 penetrating in the axial direction. Therefore, the restricting member has air permeability in the axial direction of the cover 10.

[0132] In this embodiment, the ventilation passages 61 are formed on the outer peripheral surface of the restricting member 60 at equal intervals in the circumferential direction. The cover 10 is defined by four recessed grooves formed at intervals along the axial direction and the inner peripheral surface of the cover 10. It has been done.

[0133] The ventilation passage 61 extends from one end surface of the restricting member 60 to the other end surface thereof in the axial direction. The ventilation path 61 may be formed of one or more through holes formed to allow the passage of air. For example, a central air passage formed along the axis of the restricting member 60 and a As shown in the figure, a plurality of ventilation holes are arranged in a line in the circumferential direction and are also formed to penetrate in the axial direction. The wiring 41 may be formed of a wiring 42.

When an electric heating means of a heated tobacco product is inserted into the end surface arranged on the 0 side, the aromatic group It is preferable that the cover 10 has a shape that can restrict the movement of the member 20 in the axial direction of the cover 10. Here, the shape that can restrict the movement of the fragrant base material 20 in the axial direction of the cover 10 is, for example, Any shape may be used as long as it can restrict the movement of the material of the substrate 20 to an extent that does not cause practical problems.

[0136] By forming the restricting member 60 in this manner, the restricting member 60 can In other words, the restricting member 60 supports the fragrant base material 20. This can be done.

[0137] The restricting member 60 also restricts the aerosol containing the aromatic component generated from the aromatic base material 20. As the aerosol passes through, it can cool the high-temperature aerosol. The aroma cartridge 100 is heated to a temperature that is resistant to the combustion temperature or heating temperature. For example, the aroma cartridge 100 is a cartridge for a heated tobacco product. In this case, the restricting member 60 is formed of a material having a heat resistance of about 180 to 400°C. good.

[0138] Such materials include, for example, paper, resin, rubber, wood, metal, and ceramic. However, it is more preferable to use a resin that can be molded into various shapes.

[0139] The resin may be either a thermoplastic resin or a thermosetting resin, for example, a polyolefin. resin, polyester resin, polystyrene resin, nylon resin, acrylic resin Fat, silicone resin, fluorine resin, polyurethane resin, ethylene vinyl acetate (EV A) resins, phenolic resins, amino resins, ABS resins, and biodegradable plastics Among these resins, the aroma cartridge 100 is Since these plastics become waste, biodegradable plastics are preferred from the viewpoint of protecting the natural environment.

[0140] Biodegradable plastics include, for example, poly(3-hydroxybutyrate) (PHB) , poly(ε-caprolactone) (PCL), poly(butylene succinate) (PBS), and polylactic acid (PLA).

[0141] According to this embodiment, the fragrant base material 20 disposed closest to the base end of the cover 10 is The brake member 60 allows the cover 10 to be held in place within the cover 10. When the aroma cartridge 100 is attached to the heated tobacco product 50, the aroma cartridge 100 is heated by the electric heating means 52. The scented substrate 20 can be held in a position suitable for heating.

[0142] [Embodiment 3] The fragrance cartridge 100 of the third embodiment is configured so that the fragrance substrate 20 flows out from the cover 10. The aroma cartridge 100 differs from the aroma cartridge 100 of the first and second embodiments in that it uses a lid material that prevents the lid from breaking. The same components as those of the aroma cartridge 100 of the first and second embodiments are used in the same locations. The symbols are given and the explanation is omitted.

[0143] As shown in FIG. 9, the fragrance substrate 20' in this embodiment is a granular component. In this embodiment, the fragrance substrate 20' is composed of granular components. The entire structure is cylindrical.

[0144] A lid member 70 is provided on the tip side of the cover 10 to close the opening on the tip side of the cover 10. The cover material 70 has air permeability in the axial direction of the cover. It is sufficient that the filter has the breathability required for smoking, for example, the same breathability as the filter 30. It is preferable to do so.

[0145] The lid material 70 may be, for example, a paper material such as Japanese paper, a porous material, a honeycomb structure, or a mesh structure. It can be formed by the following.

[0146] According to this embodiment, the lid member 70 closes the opening at the tip end of the cover 10, so that the fragrance The base material 20 ′ can be prevented from flowing out from the opening of the cover 10 .

[0147] [Embodiment 4] The aroma cartridge 100 of the fourth embodiment has a partition wall similar to that of the aroma cartridges of the first to third embodiments. The same configuration as the aroma cartridge 100 of the first to third embodiments is different. In the above, the same parts are denoted by the same reference numerals and the explanation thereof will be omitted.

[0148] As shown in Fig. 10, the partition wall 42 is formed in a cotton-like shape. Depending on the temperature range (e.g., 180 to 400°C) heated by the electric heating means of the cigarette Heat-resistant fibers (either natural fibers or synthetic fibers) are used. The partition wall 42 is slightly entangled in the axial direction of the cover 10. The airflow resistance is at least the same as that of the filter 30.

[0149] The shape of the partition wall is not limited to this, and 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 center thereof in the thickness direction. Each of the partition walls 43 can be fixed to the wrapping paper 11 with, for example, an adhesive. Therefore, the partition wall 43 has airflow resistance in the axial direction of the cover 10 that is at least the same as that of the filter 30. [Example]

[0160] In Example 2, the crushed raw material was impregnated with an aroma agent or a heat-melting substance, and the average The mixture was granulated to a particle size of 0.1 mm to 1.5 mm. The shape is not important as long as it is not spherical and has a volume within the range of the average particle size mentioned above. The average particle size of the compound can be measured by a laser diffraction particle size distribution measuring device. The average particle size of the mixture in this specification means the median diameter.

[0161] The thus obtained fragrant base material was wrapped in paper to a predetermined filling rate. In Examples 1 and 2, the fragrant base material was formed so that its length was 5.0 to 10.0 mm, and in Comparative Example 1, the fragrant base material was formed so that its length was 20.0 to 35.0 mm.

[0162] In Examples 1 and 2, the aroma cartridge 100 was manufactured by arranging the aroma base materials at intervals of 3.0 mm in the axial direction of the cover 10. In Example 2, the aroma cartridge 100 was manufactured by providing the lid member 70 that closes the opening on the tip side of the cover 10, as described in the above-mentioned third embodiment.

[0163] (sensory test) Using heated tobacco, the breathability and flavor of the aerosols of the aroma cartridges 100 of Examples 1 and 2 and Comparative Example 1 were evaluated by 10 panelists.

[0164] Eight out of ten panelists evaluated that the aroma cartridges 100 of Examples 1 and 2 had higher breathability and provided a better smoking experience (good aroma and flavor) than the aroma cartridge 100 of Comparative Example 1.

[0165] Furthermore, eight out of ten panelists evaluated that the aroma cartridge 100 of Example 2 had higher breathability than the aroma cartridge 100 of Example 1 and provided a better smoking experience (good aroma and flavor). [Explanation of symbols]
