Description

[Technical field]

[0001] The present invention relates to a heated aroma-generating substrate suitable for an aroma cartridge, a heated aroma-generating base body in which the heated aroma-generating substrate is wrapped in a packaging material, and an aroma cartridge equipped with the heated aroma-generating base body, as well as a manufacturing method and device for the heated aroma-generating base body. [Background technology]

[0002] In recent years, in order to comply with the trend towards smoking cessation, products that allow users to enjoy smoking by heating a cartridge containing tobacco components or non-tobacco plant components without using a flame and inhaling the vaporized components have become popular. As an example of a tobacco filler to be filled into such a heating-type aroma cartridge, an example using a continuous sheet of homogenized tobacco has been disclosed. (Patent Document 1).

[0003] Furthermore, flavorings such as menthol are added to smoking articles to change their flavor. For example, a technique has been disclosed in which menthol is encapsulated and placed inside a filter (Patent Document 2).

[0004] Also disclosed is an article that is smoked by inserting an aroma cartridge having a heated aroma-generating substrate at an end thereof and heating it (Patent Document 3).

[0005] Furthermore, various inventions relating to heated aerosol generating articles are known. For example, an invention relating to a heated aerosol generating article having a plurality of airflow paths has been disclosed (Patent Document 4). [Prior art documents] [Patent documents]

[0006] Patent Document 1: Patent No. 6017546 Patent Document 2: Special Publication No. 2017-506891 Patent Document 3: Special Publication No. 2017-519915 Patent Document 4: Special Publication No. 2016-538848 Summary of the Invention [Problem to be solved by the invention]

[0007] In the manufacturing method of the heated aroma-generating substrate constituting the heated aroma-generating body into which the heating element of the aroma cartridge is inserted, adding menthol to the filling material certainly adds a menthol flavor. However, there is a problem that the menthol flavor is lost if such a filling material is left as it is. For this reason, there are efforts to encapsulate menthol and place it in a filter, but there are problems such as high cost and complicated manufacturing method.

[0008] Furthermore, the prior art does not disclose a method for producing a heated aroma-generating substrate using a non-tobacco material, and there is a problem in that the molding is difficult and it is difficult to obtain a substrate having sufficient strength when using a non-tobacco material to produce a heated aroma-generating substrate.

[0009] Furthermore, when a user handles the aroma cartridge, such as when inserting the aroma cartridge into the smoking device body or when finishing smoking and removing the aroma cartridge from the smoking device body, the heated aroma-generating substrate may fall off the aroma cartridge or a part of the heated aroma-generating substrate may drop off, causing the inside of the smoking device body to become soiled and ultimately causing problems with the smoking device body.

[0010] The present invention has been made to solve the problems of the conventional technology described above, and aims to provide a means by which the refreshing feeling of menthol can be enjoyed in addition to the aroma and taste of the heated aroma-generating base material, and the flavor of menthol can be maintained even during long-term storage.

[0011] Another object of the present invention is to provide a means for preventing the heated aroma-generating substrate or parts thereof from falling off or dropping out of the aroma cartridge before or after use when a user handles an aroma cartridge equipped with a heated aroma-generating body consisting of a heated aroma-generating substrate wrapped in a packaging material.

[0012] Furthermore, an object of the present invention is to provide a heated aroma-generating body wrapped in a packaging material which has excellent moldability when producing a heated aroma-generating base material and which ensures a flow path for the gas generated by heating the heated aroma-generating base material, and to provide a manufacturing method and manufacturing apparatus for a heated aroma-generating body which is capable of ensuring the gas flow path.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0053] A preferred embodiment of the present invention will be described below with reference to the drawings. Note that the following will show a schematic view of the scope necessary for the description of the present invention, and will mainly describe the scope necessary for the description of the relevant parts of the present invention, and the portions for which description is omitted will be based on known techniques. Note that in the description of the drawings, the same elements are given the same reference numerals, and duplicate descriptions will be omitted. Also, the dimensional ratios of the drawings are exaggerated for the convenience of description, and may differ from the actual ratios.

[0054] FIG. 8 is a flow diagram (connection) showing the steps (means) of the method (apparatus) for producing an aroma substrate composition and a heated aroma-emitting substrate according to one embodiment of the present invention. In the following, the production method including each step will be mainly described, but it is clear that there is a production apparatus that can carry out the production method as a whole by including a means for executing each step. For this reason, the production method and the production apparatus will not be described overlapping, but will be described simultaneously (overlapping) as "steps (means)" and "method (apparatus)". In addition, the production method (apparatus) described below is a preferred example, and the production method (apparatus) for producing an aroma substrate composition and a heated aroma-emitting substrate according to the present invention is not limited to the following form.

[0055] This manufacturing method [apparatus] has a drying / grinding step [means] (A) in which the aroma base material that is the source of the aroma is dried and pulverized to obtain a dried and pulverized product. Note that this step [means] can be omitted if the raw materials can be used as they are. In addition, the method has a preparation step [means] (B) in which other materials used in manufacturing the aroma base composition and the heated aroma-emitting base material are pretreated and weighed, as necessary.

[0056] After the above-mentioned drying and grinding step [means] (A) and preparation step [means] (B), these materials are mixed under predetermined conditions in the mixing step [means] (M) to become a heated aroma-generating base material.

[0057] The heated aroma-generating substrate can be shaped into a desired shape through a filling molding step [means] (F). The heated aroma-generating substrate shaped into a desired shape is then subjected to an aroma cartridge manufacturing step [means] (G) to become an aroma cartridge.

[0058] The process (apparatus) for producing the aroma base material composition, the process (apparatus) for producing the heated aroma-emitting base material, and the process (apparatus) for producing the aroma cartridge will be described below. Details of the aroma base material used as the raw material will be described later.

[0059] First, in the drying and grinding step (A), the part of the raw aroma base material (e.g., leaves, seeds, dried fruits, stems, bark, roots, etc.) is ground into a desired form to prepare an aroma base composition. At that time, it is also preferable to adjust the moisture content to a level suitable for absorbing or supporting the aerosol former, water, and other ingredients to be added later.

[0060] The drying temperature is preferably 60° C. or higher and 80° C. or lower. Within this range, it is easy to reach the desired moisture content while avoiding the loss of the required flavor components. Furthermore, if the temperature is 65° C. or higher, it is even easier to reach the desired moisture content, and if the temperature is 75° C. or lower, it is even easier to prevent the loss of the required flavor components.

[0061] The moisture content of the dried and pulverized product after drying and pulverization is preferably 5% by mass or less. This makes it easier to make a slurry in the subsequent step [means]. The moisture content is more preferably 3% by mass or less. In addition, the moisture content is preferably 0.1% by mass or more, since it is possible to maintain a good compatibility with water, etc.

[0062] Furthermore, the drying / grinding step [means] (A) may include a sieving step [means] of sieving the dried and ground product, whereby the aromatic base composition, etc., can be provided to the mixing step [means] (M) in the form of a desired particle size.

[0063] In the preparation step [means] (B), materials required for preparing the aroma base composition and the heated aroma-generating base material are prepared and weighed. The preparation step [means] includes step [means] (B1), step [means] (B2), and step [means] (C). Step [means] (B1) is a step [means] for preparing celluloses (first binder) used as needed, and is an optional step [means]. Step [means] (B2) is a step [means] for preparing polysaccharides (second binder) prior to the second mixing step (M2) described below. Step [means] (C) is a step [means] for preparing an aerosol former. In addition to these, step [means] (E) is a step [means] for preparing flavor additives, preservatives, etc. used as needed in preparing the aroma base composition, and is an optional step [means].

[0064] The mixing step [means] (M) includes a first mixing step [means] (M1), a curing step [means] (Y) and a second mixing step [means] (M2). In the first mixing step [means] (M1), the above-mentioned drying / grinding step [means] (A), step [means] (B1), step [means] (C) and step [means] (E) are mixed to obtain a first mixture. The first mixture is cured in the curing step [means] (Y), and in the second mixing step [means] (M2), a polysaccharide (second binder) is added to the above-mentioned first mixture and mixed to obtain a second mixture (fragrance base composition). In the second mixing step [means] (M2), in addition to the polysaccharide (second binder), a flavor additive, a preservative, etc. may be added.

[0065] The second mixture (fragrance substrate composition) can be formed into a desired shape through the filling molding step (F), and is then subjected to the fragrance cartridge manufacturing step (G) as a heated fragrance-generating substrate to become a fragrance cartridge. In the description, the steps (steps) described as being divided into a plurality of steps (steps) may be performed simultaneously or in parallel as necessary. For example, the above description shows a form in which the materials prepared in steps (B1) and (C) are mixed in advance before the first mixing step (M1), but this is not limited thereto, and the materials prepared in steps (A), (B1), (C), and (E) may be mixed simultaneously in the first mixing step (M1).

[0066] The heated aroma generating substrate according to the present invention includes an aerosol former. As the aerosol former, glycerin, propylene glycol, sorbitol, triethylene glycol, lactic acid, diacetin (glycerin diacetate), triacetin (glycerin triacetate), triethylene glycol diacetate, triethyl citrate, isopropyl myristate, methyl stearate, dimethyl dodecanedione, dimethyl tetradecanedione, etc. can be used, and glycerin and propylene glycol are particularly preferred. These aerosol formers can be used alone or in combination of two or more kinds.

[0067] The content of the aerosol former in the heated aroma-generating base material is preferably from 1% by mass to 80% by mass, more preferably from 10% by mass to 40% by mass, and most preferably from 20% by mass to 35% by mass, relative to the total amount of the heated aroma-generating base material.

[0068] The content of the aerosol former in the heated aroma-generating base material is preferably from 30 to 100 parts by mass, particularly preferably from 50 to 80 parts by mass, per 100 parts by mass of the aroma base material.

[0069] Furthermore, flavor additives that add flavor as needed are also preferably used. Examples of flavor additives include mint, cocoa, coffee, black tea extract, xylitol, etc. Also, food preservatives such as sorbic acid, potassium sorbate, benzoic acid, sodium benzoate, etc. may be added as needed. These ingredients may be used alone or in combination of two or more.

[0070] In one embodiment of the present invention, the heated aroma-generating substrate comprises microcrystalline cellulose.

[0071] Microcrystalline cellulose is obtained, for example, by partially depolymerizing α-cellulose obtained from the pulp of a fibrous plant with an acid, removing the soluble portion, and appropriately crystallizing the insoluble portion, and is distinguished from celluloses used as binders or thickeners described below.

[0072] After various studies, the following was found about the aroma base material, the aerosol former, and the heated aroma-generating base material containing microcrystalline cellulose. That is, when the heated aroma-generating base material is placed under dry conditions, even if the heated aroma-generating base material loses water, the cellulose microcrystals maintain the structure of the heated aroma-generating base material and suppress structural changes such as volumetric shrinkage. It is believed that such an effect is obtained by using microcrystalline cellulose.

[0073] In one embodiment of the present invention, the microcrystalline cellulose is weighed in the preparation step [means] (B) and then subjected to the mixing step [means] (M). The microcrystalline cellulose may be in the form of a powder, or may be dispersed in a solvent such as water and subjected to the mixing step [means] (M) as a suspension. In this case, the dispersion of the microcrystalline cellulose in the solvent can be carried out using a high-speed stirrer or a high-pressure homogenizer.

[0074] The content of microcrystalline cellulose in the heated aroma-generating base material is preferably 1% by mass or more and 15% by mass or less, more preferably 3% by mass or more and 12% by mass or less, and even more preferably 5% by mass or more and 10% by mass or less, relative to the total amount of the heated aroma-generating base material.

[0075] The addition of microcrystalline cellulose improves the moldability of the heated aroma-generating base material and improves the workability when kneading each component with a roll mill, and is particularly effective in suppressing the shrinkage and volume change of the heated aroma-generating base material. Therefore, the addition of microcrystalline cellulose is also effective from the viewpoint of quality control of the aroma cartridge and uniformity of the feeling of use.

[0076] The average particle size of the microcrystalline cellulose used in the present invention is preferably 30 μm to 200 μm, more preferably 50 μm to 150 μm, and even more preferably 70 μm to 120 μm. When the average particle size of the microcrystalline cellulose is 30 μm or more, it is excellent in the effect of suppressing the shrinkage of the heated aroma-generating substrate, and when it is 200 μm or less, it is possible to improve the moldability of the heated aroma-generating substrate in addition to the effect of suppressing the shrinkage of the heated aroma-generating substrate.

[0077] The average particle size of microcrystalline cellulose is determined by a sieving method. The average particle size can be obtained by the method described in JIS K 0069:1992. The average particle size refers to the diameter equivalent to 50% of the mass of the sieves with larger openings, for example, calculated from the test results using multiple sieves.

[0078] Furthermore, the amount of residue on a sieve with a mesh size of 250 μm is preferably 8 mass% or less relative to the total amount of microcrystalline cellulose, and the amount of residue on a sieve with a mesh size of 75 μm is preferably 45 mass% or more relative to the total amount of microcrystalline cellulose.

[0079] When the residue on a 250 μm sieve is 8% by mass or less, the microcrystalline cellulose is more likely to exhibit the effect of suppressing the shrinkage of the heated aroma-generating base material.When the residue on a 75 μm sieve is 45% by mass or more, the microcrystalline cellulose is more likely to exhibit the effect of improving the moldability of the heated aroma-generating base material.

[0080] The mass average molecular weight (Mw) of the microcrystalline cellulose is preferably 10,000 or more and 200,000 or less. When it is 10,000 or more, it is excellent in the effect of suppressing the shrinkage of the heated aroma-generating base material, and when it is 200,000 or less, it can further improve the effect of improving moldability in addition to the effect of suppressing the shrinkage. The mass average molecular weight is more preferably 20,000 or more and 60,000 or less.

[0081] The molecular weight of cellulose can be measured by gel permeation chromatography (GPC), for example, the method described in JP-A-6-109715, and polyethylene glycol or the like is appropriately used as a standard sample.

[0082] In one embodiment of the present invention, the heated aroma generating substrate comprises menthol and polyvinylpolypyrrolidone (a water insoluble crosslinked polymer).

[0083] In the case where menthol and polyvinylpolypyrrolidone are contained, in the preparation step [means] (B), menthol, lower alcohol, and polyvinylpolypyrrolidone (water-insoluble crosslinked polymer) are weighed, and then the weighed menthol, lower alcohol, and polyvinylpolypyrrolidone are mixed to obtain a menthol solution, in which menthol, lower alcohol, and polyvinylpolypyrrolidone are mixed and dissolved. Preferably, menthol is dissolved in lower alcohol, and then polyvinylpolypyrrolidone is added and mixed.

[0084] Here, menthol is not limited to that obtained from natural products, but may be a synthetic product. In addition, peppermint, mint, peppermint oil, and other substances containing menthol may be used. The lower alcohol is a solvent that dissolves menthol, and ethyl alcohol is particularly preferably used.

[0085] In the present invention, the water-insoluble crosslinked polymer refers to a non-crosslinked polymer that is soluble in water and crosslinked to become water-insoluble and swell.Of course, it is preferable that the water-insoluble crosslinked polymer does not dissolve in lower alcohol and swells, and such a polymer is selected and used in the present invention.The water-insoluble crosslinked polymer such as polyvinyl polypyrrolidone has a hydrophilic part and a hydrophobic part, and it is considered that the hydrophilic part contributes to swelling and the hydrophilic part is oriented toward menthol, thereby exerting the effect of the present invention.

[0086] As one embodiment of the heated aroma generating substrate of the present invention, it is preferable to use polyvinyl polypyrrolidone, which is a crosslinked product of polyvinyl pyrrolidone, as the water-insoluble crosslinked polymer. If it contains polyvinyl polypyrrolidone, the heated aroma generating substrate of the present invention may contain other water-insoluble crosslinked polymers other than polyvinyl polypyrrolidone as the water-insoluble crosslinked polymer. As another water-insoluble crosslinked polymer, there may be mentioned crosslinked polysaccharides which are crosslinked to water-soluble polysaccharides to make them water-insoluble. As the crosslinked polysaccharide, there may be mentioned polysaccharides which are epoxy crosslinked, ester crosslinked, ether crosslinked, etc.

[0087] In another preferred embodiment of the heated aroma-generating substrate, the above-mentioned other water-insoluble crosslinked polymers can be used instead of polyvinyl polypyrrolidone. Examples of the other water-insoluble crosslinked polymers include crosslinked polysaccharides that are made water-insoluble by crosslinking water-soluble polysaccharides. Examples of crosslinked polysaccharides include polysaccharides that are epoxy-crosslinked, ester-crosslinked, ether-crosslinked, etc.

[0088] The content of menthol is sufficient if it is added in an amount that targets the desired flavor. To impart menthol flavor, the content of menthol in the heated aroma-generating base material is approximately 0.1% by mass to 10% by mass relative to the total amount of the heated aroma-generating base material. Another guideline is that the content is preferably 0.2% by mass to 5% by mass.

[0089] In the heated aroma-generating base material, the content of polyvinyl polypyrrolidone per 100 parts by mass of menthol is from 50 to 600 parts by mass. In other words, the content of polyvinyl polypyrrolidone is from 0.5 to 6 times the content of menthol.

[0090] In another embodiment of the present invention, in the heated aroma-generating substrate, the content of polyvinyl polypyrrolidone (water-insoluble crosslinked polymer) relative to 100 parts by mass of menthol is 10 parts by mass or more and 2000 parts by mass or less. In other words, the content of polyvinyl polypyrrolidone (water-insoluble crosslinked polymer) is 0.1 times or more and 20 times or less the content of menthol.

[0091] In order to achieve the effects of the present invention, the content of polyvinyl polypyrrolidone in the heated aroma-generating substrate is preferably 2% by mass or more, more preferably 4% by mass or more, based on the total amount of the heated aroma-generating substrate. By including such an amount, the effects of the present invention in terms of long-term storage stability can be more effectively achieved. Furthermore, the content of polyvinyl polypyrrolidone in the heated aroma-generating substrate is in a range not exceeding 10% by mass (10% by mass or less). This is because when the content is 10% by mass or less, the flavor derived from polyphenols and the like derived from the aromatic substrate can be maintained.

[0092] The amount of the lower alcohol used is preferably 50 parts by mass or more relative to 100 parts by mass of menthol. Furthermore, when the amount of the lower alcohol used is 100 parts by mass or more, the effect of being able to sufficiently mix polyvinyl polypyrrolidone while dissolving menthol is obtained. Furthermore, when the amount of the lower alcohol used is 2000 parts by mass or less, the amount of residual lower alcohol in the subsequent step [means] can be reduced, and therefore an efficient manufacturing step [means] can be obtained.

[0093] In one embodiment of the present invention, the heated aroma-generating substrate preferably contains a polysaccharide. As the polysaccharide, it is particularly preferable to use one that is water-soluble, swells when it absorbs water, or gels, and the use of such a polysaccharide contributes to moldability.

[0094] Examples of polysaccharides contained in the heated aroma-generating substrate according to the present invention include konjac mannan (glucomannan), guar gum, pectin, carrageenan, locust bean gum, and agar. These polysaccharides can be used alone or in combination of two or more. In particular, from the viewpoint of improving moldability, it is preferable to use konjac mannan (glucomannan) as the polysaccharide.

[0095] In one embodiment of the present invention, it is preferable to further add celluloses (first binder) to the heated aroma-generating substrate containing the polysaccharide. The celluloses contained in the heated aroma-generating substrate according to the present invention include cellulose, cellulose derivatives, and metal salts thereof. As the celluloses, those that are particularly water-soluble are preferably used in order to bind (bond) the aroma substrate.

[0096] Examples of celluloses that can be used in the present invention include methyl cellulose, ethyl cellulose, carboxymethyl cellulose, carboxyethyl cellulose, hydroxymethyl cellulose, hydroxyethyl cellulose, and hydroxypropyl cellulose, as well as metal salts thereof such as sodium salts, potassium salts, and calcium salts. These celluloses can be used alone or in combination of two or more. In particular, it is preferable to use metal salts of celluloses, and it is more preferable to use at least one selected from the group consisting of sodium salts, potassium salts, and calcium salts of carboxymethyl cellulose, and it is particularly preferable to use sodium carboxymethyl cellulose, which is easily available.

[0097] The content of cellulose in the heated aroma-generating base material is preferably 1 part by mass or more and 30 parts by mass or less, more preferably 2 parts by mass or more and 20 parts by mass or less, even more preferably 5 parts by mass or more and 20 parts by mass or less, and particularly preferably 10 parts by mass or more and 20 parts by mass or less, per 100 parts by mass of the aroma base material.

[0098] When the heated aroma-generating substrate contains cellulose, it is prepared as step [means] (E) shown in Fig. 8. In this step [means] (E), a component other than cellulose may be further prepared as another first binder. Examples of the first binder other than cellulose include konjac mannan (glucomannan), guar gum, pectin, carrageenan, tamarin seed gum, gum arabic, soybean polysaccharides, locust bean gum, karaya gum, xanthan gum, and agar. These components can be used alone or in combination of two or more kinds.

[0116] Furthermore, extracts of the above-listed aromatic base materials, so-called extracts, can also be used. The form of the agent may be liquid, starch syrup, powder, granules, solution, or the like.

[0117] The above-mentioned aromatic base materials can be used alone or in combination of two or more kinds. Among the fragrance base materials, those that do not require drying and pulverization are directly subjected to the mixing step [means] (M). It is also possible.

[0118] Next, the mixing step [means] (M) will be described. As described above, the mixing step [means] (M) is , the first mixing step [means] (M1), the curing step [means] (Y) and the second mixing step [means] ](M2).

[0119] The raw material, the aromatic base material, is dried and crushed (A) and prepared (B). The mixture is then subjected to a mixing step (M) or directly.

[0120] In the mixing step (M), a fragrance base material, an aerosol former, and the above-mentioned Microcrystalline cellulose, menthol, polyvinylpolypyrrolidone (a water-insoluble cross-linked polymer) ), water, etc., are added and mixed to obtain a heated aroma-emitting base material.

[0121] When the heated aroma-generating substrate contains polysaccharides or cellulose, first, the process shown in FIG. In step (B1), cellulose (first binder) is prepared as needed. Then, after mixing in the first mixing step [means] (M1) to obtain a first mixture, In B2), a polysaccharide (a second binder) is prepared, and in a second mixing step (M2), the polysaccharide is mixed with a second binder. It is preferable to add the polysaccharide as a binder after obtaining the first mixture. A curing step [means] of holding (curing) the first mixture at a predetermined temperature for a predetermined time before the curing step It is more preferable to add (Y).

[0122] When the solution viscosity of the cellulose (first binder) is 300 mPa·s or more, the aromatic It is preferable because it is easy to mix with the fragrance base material. Also, the cellulose (first binder) has a high viscosity in its solution. A viscosity of 5,000 mPa·s or more is suitable for binding (bonding) aromatic base materials. On the other hand, the solution viscosity of the cellulose (first binder) is 50,000 mPa. When used with polysaccharides (secondary binders), the binding (binding) of the fragrance substrate is improved. This is preferable because it is easy to adjust the strength of the effect.

[0123] In this specification, the term "solution viscosity" is measured using a Brookfield viscometer. A 1% by weight aqueous solution of the component was prepared and rotated at 10 to 30 rpm (0.17 to 1.25°C) in an environment of 25°C. 0.5 s-1), this is the measurement value when the rotor starts rotating and the displayed value stabilizes.

[0124] In the second mixing step (M2), a conventional mixer can be used. For example, a mixer that mixes the materials in a mixing tank while applying shear force with an agitating blade is preferred. It is also commonly used in the form of kneading using a roll mill, kneader, extruder, etc. In this case, the mixing temperature is preferably 40° C. or less, more preferably 50° C. or less. It is preferable to control the temperature to be kept at 30°C or lower, and even more preferably at about 25°C. If excessive heat is applied during mixing, the flavor may dissipate. It is also preferable to pass cooling water through the container to adjust the temperature.

[0125] The heated aroma-generating substrate manufactured through the curing process [means] (Y) is attached to the smoking device body and smoked. Smoking improves the flavor of the aroma base material, especially when tea is used as the aroma base material. Therefore, according to a preferred embodiment of the present invention, a fragrance base material and The aerosol former and the cellulose (first binder) are mixed to obtain a first mixture. First mixing step [means] (M1), the first mixture is mixed in a sealed state at a predetermined temperature for a predetermined time A curing step [means] (Y) of holding the first mixture, and the first mixture having undergone the curing step [means] (Y). The method further comprises a second mixing step (M2) of adding polysaccharide as a second binder to the mixture and mixing the mixture. The present invention provides a method and apparatus for producing a heated aroma-emitting substrate.

[0126] The temperature of the curing step (Y) is preferably 15°C or higher and 30°C or lower. If the temperature is below 30℃, the flavor is improved. The temperature is more preferably 18°C ​​or higher and 24°C or lower.

[0127] The time for the curing step [means] (Y) is preferably 72 to 336 hours. If it is more than 336 hours, the flavor will improve, and if it is less than 336 hours, the flavor will be suppressed and the flavor will be improved. This is because the improvement is maintained for 96 to 192 hours. The incubation time is preferably 96 to 168 hours, and most preferably 125 to 150 hours.

[0128] In the curing step (Y), the first mixture is cured under closed conditions. This is to prevent the flavor from dissipating.

[0129] In the second mixing step (M2) of adding the polysaccharide, other components other than the polysaccharide are added. may be further added as another second binder. Such another second binder may include: Cellulose, tamarin seed gum, gum arabic, soy polysaccharides, karaya gum, xanthan Examples of the ingredients include gum, starch, corn starch, etc. These ingredients may be used alone or in combination. A mixture of two or more species can also be used.

[0130] Polysaccharides (second binders) have a solution viscosity of more than 50,000 mPa·s, and therefore have a high degree of aromaticity. This is preferable because it is suitable for strengthening the bond between the substrates. The viscosity was measured using a Brookfield viscometer. A 1% by weight aqueous solution of the component was prepared. Start rotating the rotor at 10-30 rpm (0.17-0.5 s-1) in an environment of 25°C. The measured value is the value at which the reading stabilized. The viscosity exceeded 100,000 mPa·s, which is the upper limit of the measurement of the Gelfield viscometer. This is also fine.

[0131] When polysaccharides (second binder) are added to the heated aroma-generating base material, In step (F), the aroma-generating substrate to be heated can be easily molded into a desired shape. The aroma-generating substrate to be heated has sufficient strength and is easy to mold. The reason why it is preferable to add the binder in the second mixing step is that the binder is This makes mixing easier than adding it in the mixing process [means], and allows the mixture to be adjusted to an appropriate hardness. However, the timing of mixing the polysaccharide (second binder) is important. The mixing method is not limited to this, and the mixing method may include mixing a polysaccharide (second binder) in the first mixing step [means]. may be carried out.

[0132] In addition, the polysaccharide (second binder) has a solution viscosity that is equal to or smaller than the solution viscosity of the first binder. By selecting such a polysaccharide (second binder), In the filling molding step (F), the processability (moldability) of the heated aroma-generating substrate is improved. In particular, glucomannan has good processability (moldability) and is preferably used.

[0133] The content of the polysaccharide (second binder) in the heated aroma-generating base material is 100% by mass of the aroma base material. By setting the content in this range, the aromatic The moldability of the generating base material is improved, and the natural aroma and flavor of the fragrance base material can be enjoyed. A heated aroma-generating substrate is obtained. Furthermore, the polysaccharide (second binder) in the heated aroma-generating substrate is The content of is preferably 0.2 to 3 parts by mass relative to 100 parts by mass of the aromatic base material, It is more preferable that the content is 0.3 to 1 part by mass.

[0134] The mixture thus obtained is subjected to a filling forming step [means] (F) to obtain a desired filling ( The product is in the form of a heated aroma-generating substrate.

[0135] The molding method used in the filling molding step (F) is a method of pressing the fragrance base composition. a method of passing the composition through an orifice and shaping it into a rod-like shape; Then, the aromatic base composition is cut into a desired shape, or the aromatic base composition is dried and crushed into granules. Methods etc. can be exemplified.

[0136] In the following, the fragrance base material composition is formed into a thin sheet and then cut into a desired shape. The method is explained in detail. In order to make the fragrance base composition into a thin sheet, three roll mills are used. A three-roll mill can be used. The material is compressed by the roll speed difference and sheared by the roll speed difference, and the material is mixed and dispersed. This is preferred because it is possible to cut the sheet into a desired thickness using a cutter blade. It is also preferable to prepare the sheet by using a press roller or a press machine.

[0137] In the filling forming step (F), a fragrance base material, an aerosol A fluoropolymer, a binder or thickener, a flavor additive, a preservative, etc. may be further added, and water, etc. may be added.

[0138] The water used in the present invention should be sterilized or have had microorganisms removed. It is preferable to use pure water obtained by reverse osmosis or ion exchange. .

[0140] In another embodiment of the present invention, the thickness of the sheet of the obtained fragrance base composition is 0.1 to 1.0 mm.

[0141] As a specific example of the filling molding step [means] (F), a 0.3 mm thick aromatic base material composition An example of cutting the sheet into a desired shape to prepare a heated aroma-emitting substrate will be described. For example, The sheet of the fragrance base composition is cut into a rectangle measuring 150 mm in length and 240 mm in width. The sheet is fed to a rotary cutter and cut into a shape of 1.5 mm length and 240 mm width. The cut pieces of the sheet are obtained. 31 pieces of the cut pieces of the sheet are wrapped in tobacco paper and cut into pieces with an outer diameter of 5.5 mm. A roll is prepared. The roll is cut into strips of 42.0 mm length with a cutter. A heated aroma generating body having a heated aroma generating substrate can be obtained. The mass of the generating substrate is 0.63 g. If the ratio of the volume of the generated substrate is the volume filling rate, in the above case, the volume filling rate is 0.59. This allows the aroma generating capacity to be calculated based on the volumetric filling rate and the mass of the aroma generating base material to be heated. The density of the substrate is 1.07 g / cm 3 It becomes.

[0142] As a specific example of the filling forming step [means] (F) according to another aspect of the present invention, a filling having a thickness of 0. A 3 mm sheet of the aroma base composition is cut into the desired shape to prepare a heated aroma-emitting substrate. An example will be described. For example, a sheet of the fragrance base composition is placed in a rectangular shape having a length of 150 mm and a width of 240 mm. The cut sheet is fed to a rotary cutter and cut into pieces 1.5 mm long and 2 mm wide. The sheet is cut into 40 mm pieces to obtain cut pieces of the sheet. 50 pieces of the cut pieces of the sheet are then cut into 40 mm pieces of the tobacco paper. The roll is wound with a wire cutter to produce a roll with an outer diameter of 6.9 mm. The heated aroma-generating body having a rectangular heated aroma-generating substrate can be obtained by cutting the substrate to length. In this case, the mass of the aroma-generating substrate to be heated is 0.29 g. If the ratio of the volume of the aroma-generating substrate to the total volume is defined as the volume filling rate, then in the above case, The filling rate is 0.60. From this, the calculation based on the volume filling rate and the mass of the heated aroma-generating base material is The density of the filling is 1.07 g / cm 3 It becomes.

[0143] The heated aroma generating body obtained in the above-mentioned filling forming step [means] (F) is in the shape of a strip or a rod. A plurality of heated aroma-generating substrates are arranged along the longitudinal direction of the aroma cartridge.

The aroma-generating substrate to be heated has a cross section perpendicular to the longitudinal direction that is a perfect circle or ellipse. In addition, in the case of a "rod-shaped heated aroma-generating substrate," the "outer diameter" refers to the diameter of a rod having a cross section of a perfect circle. In the case of an elliptical shape, the length of the major axis is referred to as the diameter. In the specification, even if the cross section perpendicular to the longitudinal direction is polygonal, it is considered to be a "rod-shaped load "Thermal aroma emitting substrate" and the polygon has the largest diameter among one or more circles circumscribing the polygon. The diameter of the circumscribing circle is the "outer diameter."

[0145] Therefore, a clear distinction is made between the "strip-shaped heated aroma-emitting substrate" and the "rod-shaped heated aroma-emitting substrate." First, in the case of a "strip-shaped heated aroma-emitting substrate" and a "rod-shaped heated aroma-emitting substrate" This also includes.

[0190] As described above, the aroma-generating substrate containing microcrystalline cellulose is used to produce the aroma capsule of the present invention. The cartridge is designed to suppress changes over time, such as reductions in length, width, thickness and volume, after manufacture. This can prevent problems such as the heated aroma-emitting substrate falling off from the aroma cartridge. In addition to reducing the amount of oxygen that can enter the aerosol, it also reduces the amount of oxygen that can enter the aerosol. It is possible to suppress these problems and maintain a good feeling of use and make it uniform regardless of the time that has passed since production. It is also effective in

[0191] It also contains menthol and polyvinylpolypyrrolidone (a water-insoluble cross-linked polymer). The properties of the heated aroma-generating substrate can be confirmed by the following method. A method for observing the loss of menthol contained in a base composition or a heated aroma-generating base material. It is law.

[0192] In the present invention, the prepared heated aroma-emitting substrate is placed in an environment of 17°C and a relative humidity of 65%. After weighing out 5g to 10g, seal it in a polyethylene bag and store it for 24 or 48 hours. After 24 or 48 hours, the surface of the heated aroma-generating substrate was Observe the liquid and observe the state of precipitation of white crystals. This means that the molecules are crystallizing while sublimating from the heated aroma-emitting substrate. Keep the container sealed and store it in an environment of 17℃ and 65% relative humidity for 3 hours. Then open it and The aroma-generating substrate is then weighed precisely to determine the change in mass. It is now possible to quantitatively measure the loss.

[0193] The reason for carrying out the storage test in an environment of 5℃ is to suppress the dissipation of other components of the heated aroma-generating base material. This is because the conditions are good for evaluating the state of menthol dissipation. Preventing the precipitation of crystals is important because the fragrance cartridges are packaged and distributed to the market after production. When the product is placed, transported, or stored, consumers may feel uncomfortable when they see precipitated menthol. It also has the effect of preventing

[0194] In the present invention, about 5 g to 10 g was weighed out in an environment of 17° C. and a relative humidity of 65% RH. The menthol content in the aroma-generating substrate after heating is designated as d(0), and the substrate is left at 5°C for 24 hours. The mass of the heated aroma-generating substrate is d(24), and the aroma generated after being left at 5°C for 48 hours is The menthol reduction rate d when the mass of the base material is d(48) is defined by the following formula. d={(d(24)-d(48)} / d(0)

[0195] Here, the reason for subtracting d(48) from d(24) in the above formula is that the dissipation components other than menthol The dissipation component from 24 to 48 hours is the white crystals mentioned above. This is because it better reflects precipitation.

[0196] In the present invention, when d is 0.60 or less, the precipitation of white crystals can be suppressed. It is preferable that d is 0.50 or less, and more preferably 0.30 or less. It is more preferable that the ratio is 0.20 or less, and particularly preferable that the ratio is 0.20 or less.

[0197] The aroma cartridge of the present invention described above has a relatively large surface area, so that the menthol content can be easily felt during smoking. However, this shape makes it easier for the menthol to sublimate. It contains menthol such as menthol and polyvinylpolypyrrolidone (a water-insoluble cross-linked polymer). If a heated aroma-generating substrate is used, when the aroma cartridge is shaped as described above, Even if the menthol is not sublimated, the sublimation of menthol can be effectively suppressed. In the above, menthol is dissolved in a lower alcohol, preferably ethyl alcohol, in advance. By using such a material, it is possible to obtain an even more excellent effect of inhibiting the sublimation of menthol.

The noodle-shaped heated aroma-generating substrate primary agglomerates (232) are formed into agglomerates (234), and the noodle-shaped heated aroma-generating substrate primary agglomerates (232) and the noodle-shaped heated aroma-generating substrate primary agglomerates (234) are formed into agglomerates (234). Between the primary aggregate of thermal aroma generating substrate (232) and the noodle-shaped heated aroma generating substrate single body (231) The large noodle-shaped heated aroma-generating substrate secondary agglomerates forming gas flow passages (235) begin to form. In the outer peripheral region, the noodle-shaped heated aroma-generating substrate (231) and the noodle-shaped heated aroma-generating A heated aroma generating material is placed between the substrate primary aggregate (232) and the heated aroma generating material packaging web (712). Generator wrapping web forming gas flow passages (241) are also formed.

[0253] Furthermore, in Fig. 9-5(D), the winding guide (3) (733) passes through the groove near the full moon. As the state shown in Figure 9-5(C) progresses, the garniture tape (721) and the heated area The scent generating material packaging web (712) moves along the groove in a direction perpendicular to the conveying direction, forming a circle. In the peripheral region, the noodle-shaped heated aroma generating substrate primary aggregate (232) and the noodle-shaped heated aroma generating substrate primary aggregate (233) are arranged. The noodle-shaped heated aroma-generating substrate (23) constituting the generating substrate secondary aggregate (234) slides The noodle-shaped heated aroma-generating substrate (23) moves so that the major axis of the cross section perpendicular to the noodle-shaped heated aroma-generating substrate (23) is aligned with the adjacent noodle-shaped As the frequency of contact with the major axis of the vertical cross section of the heated aroma-generating substrate (23) increases, The number of noodle-shaped heated aroma-generating substrates (23) arranged in the tangential direction of the circumference is also large. and the packing rate of the noodle-shaped heated aroma-generating substrate (23) in the outer peripheral region begins to increase. The central region is a noodle-shaped heated aroma-generating substrate primary aggregate (232) and a noodle-shaped heated aroma-generating substrate The secondary aggregates (234) remain, and the noodle-shaped heated aroma-generating substrate primary aggregate formation gas flow path (233) and the noodle-shaped heated aroma-generating substrate secondary aggregate formation gas flow path (235) are greatly reduced The voids in the outer periphery region are not as large as those in the inner periphery region, and the voids in the outer periphery region are beginning to become more numerous than in the outer periphery region.

[0254] In FIG. 9-5(E), the garniture tape (721) and the heated aroma generating device packaging The web (712) is completely wound up along the groove in a direction perpendicular to the conveying direction, and the rod-shaped heated The scent-generating body (25) is formed. In this state, the state of FIG. 9-5(D) progresses further, The internal structure of the rod-shaped heated aroma generating unit (25) is fixed. In the central region of (25), a bulky noodle-shaped heated aroma-generating substrate primary aggregate (232) and a noodle-shaped The heated aroma generating base secondary aggregates (234) remain, and the noodle-shaped heated aroma generating base material contained therein Aroma-generating substrate primary aggregate forming gas flow path (233) and noodle-shaped heated aroma-generating substrate secondary aggregate Due to the formed gas flow passage (235), the porosity is high and irregular gas flow passages are secured. The outer peripheral region is made up of a noodle-shaped heated aroma-generating substrate single body (231) and a noodle-shaped heated aroma-generating substrate primary body (232). A heated aroma generating material package is provided between the aggregate (232) and the heated aroma generating material package web (712). The gas flow passages (241) are also formed, but the noodle-shaped heated aroma-generating substrate is a primary aggregate. The noodle-shaped heated aroma generating substrate (232) and the noodle-shaped heated aroma generating substrate (234) constituting the secondary agglomerate (234) The aroma-generating substrate (23) slides and moves, and the cross section perpendicular to the noodle-shaped heated aroma-generating substrate (23) The major axis direction of the adjacent noodle-shaped heated aroma-generating substrate (23) is aligned along the major axis direction of the vertical cross section of the adjacent noodle-shaped heated aroma-generating substrate (23). As the frequency of contact with the surface increases, the major axis of the surface changes to a noodle-shaped surface aligned in the tangent direction of the circumference. The number of the aroma-generating substrates (23) is also large, and the filling rate of the noodle-shaped aroma-generating substrates (23) in the outer peripheral region is This results in a high and stable structure.

[0255] The internal structure of the rod-shaped heated aroma generating unit (25) is as follows: The cross section perpendicular to the longitudinal direction of the noodle-shaped heated aroma-generating substrate (23) is uniformly Therefore, the cross-sectional structure perpendicular to the longitudinal direction of the rod-shaped heating aroma generating unit (25) is uniform. At the same time, the noodle-shaped heated aroma-generating substrate primary aggregate forming gas flow path (233), the noodle-shaped heated The aroma generating substrate secondary aggregate forming gas flow path (235), and the heated aroma generating material wrapped web form The irregular gas flow passage of the gas flow passage (241) penetrates the rod-shaped heating aroma generating unit (25) in the longitudinal direction. Therefore, the aroma generating rod (25) is cut to produce a heated aroma generating rod (25). The internal structures of the living body (2) and the rod-shaped heat-generating aroma generating device (25) are substantially the same.

[0256] FIG. 9-6 shows an enlarged cross section of the heated aroma generating unit (2) taken perpendicular to the longitudinal direction. is the same as the cross-sectional view of FIG. 9-5(E), and approximately the same structure is formed in the longitudinal direction. Therefore, when smoking is performed using an aroma cartridge equipped with the heated aroma generating unit (2), The problems with conventional aroma cartridges have been resolved, and the aerosol smoke and aroma are delivered to the smoker's mouth. Not only can the smoke be enjoyed comfortably, but the smoke from the outside can also be absorbed sufficiently. The filling rate of the heated aroma-generating substrate is higher than that of the central region, so that the end and The structure is strong against pressure from the outer periphery and is therefore resistant to damage caused when removing and attaching the aroma cartridge. The heated aroma generating base material does not fall off, ensuring the appropriate number of puffs and reducing the amount of heat applied when inhaling. There is no problem of burning the thermal aroma generating substrate. In addition, the filling rate of the central region is low. This makes it easier to insert the fragrance cartridge into the heating element of the heated fragrance device.

[0257] The heated aroma generating unit (2) manufactured in this embodiment is a set of 50 noodle-shaped heated aroma generating units. The raw substrate (23) is wound up with a heated aroma generating material packaging material web (712), and cut into pieces. (9) By cutting it, it is finished to an outer diameter of about 6.9 mm and a length of 12.0 mm. The mass of the aroma generating body (2) is 0.29 g, and the ratio of the aroma generating body (2) to the volume of the aroma generating body (2) is 0.29 g. The volumetric filling rate of (21) is about 0.60, and the density of the heated aroma generating body (2) is 1.07 g / cm m <3> The heated aroma generating device thus produced was used to produce the aroma shown in FIG. , 2, 4-7, and 10-17 can be applied to the aromatic cartridges depicted in It was fully compatible with the heated fragrance devices available on the market.

[0258] The above is a solution to the problem of the heated aroma generating substrate falling off when the aroma cartridge is attached to or detached from the smoking tool. The heated aroma generating substrate in the heated aroma generating unit is used to the extent that there are no problems with the aroma generating device or the aroma generating device burning during inhalation. Even if the filling rate is increased, the flow path of the gas generated by heating is secured, allowing comfortable inhalation. The heated aroma emitter ensures the appropriate number of puffs per unit. However, the present invention is not limited to this. Includes everything that is encompassed by thought.

[0259] That is, the heated aroma-generating unit of the present invention is a heated aroma-generating substrate that is wrapped in a packaging material. The aroma-generating substrate to be heated is assembled into a primary aggregate to form a void gas flow path; The heated aroma-generating substrate and its primary aggregates are assembled into secondary aggregates, forming voids in the gas. A gap formed when the flow path, the heated aroma-generating base material and the primary aggregate thereof come into contact with the packaging material. and a gas flow passage having a different shape passing through the heated aroma generating body. The heated aroma generating device is characterized by having a gas flow path. The heated aroma generating body has a sufficient gas flow path, so that the heated aroma generating substrate By solving the problem of combustion, sufficient aerosol smoke and fragrance can be comfortably inhaled, and the heating type fragrance device It can be easily inserted into the heating element, while the filling rate of the heated aroma-generating substrate is high. This allows for an appropriate number of cigarettes to be smoked, and the heated aroma generating base is There is no problem with materials falling off.

[0260] Furthermore, such a non-uniform gas flow path has a cross section perpendicular to the longitudinal direction of the heated aroma generating body. When the area of ​​the central region and the area of ​​the peripheral region are equally divided, the central region has a higher porosity than the peripheral region. This is preferable in terms of exerting the above-mentioned effects.

[0261] The aroma generating substrate to be heated that constitutes such an aroma generating unit to be heated is The straight cross-sectional shape is uniform in the longitudinal direction, and the length of the long axis and the length of the short axis of the cross section perpendicular to the longitudinal direction are The aspect ratio of the film to the side is preferably 1:1 to 30:1, and more preferably 2:1 to 20:1. More preferably, the ratio is 5:1 to 20:1, and even more preferably, the ratio is 5:1 to 20:1. If the aspect ratio of the length to the minor axis is greater than 30:1, it becomes difficult to secure a gas flow path. It becomes.

[0262] As can be seen from this aspect ratio, the cross section perpendicular to the longitudinal direction of the heated aroma-generating substrate is The surface shape is not particularly limited, and may be an isotropic equilateral triangle, a square, or a regular pentagon. There is no problem with a regular polygon such as a circle, but in order to ensure a non-standard gas flow path, The aspect ratio is preferably 2:1 or more, and the shape is approximately rectangular or approximately elliptical. is preferred.

[0263] In particular, the aroma-generating substrate to be heated has a cross-sectional shape of a substantially rectangular parallelepiped, and the cross-sectional shape is substantially rectangular. It is most preferable to form such a long rectangular parallelepiped to ensure a gas flow path. The length of the minor axis of the cross section perpendicular to the direction is preferably 0.1 to 1.0 mm, and more preferably 0.1 to The length of the long axis of the cross section perpendicular to the longitudinal direction of the rectangular parallelepiped is preferably 0.5 mm. It is preferably 0.5 to 3.0 mm, and more preferably 0.5 to 2.0 mm. stomach.

[0264] In addition, the cross-sectional shape of the heated aroma-generating substrate perpendicular to the longitudinal direction is uniform in the longitudinal direction. The aroma generating device is a long product in which the aroma generating substrate is wrapped in a packaging material. The most suitable position is chosen to ensure uniformity of direction and to ensure that the gas flow path penetrates the heated aroma emitter. preferable.

[0265] On the other hand, the length of the minor axis of the cross section perpendicular to the heated aroma generating substrate constituting the heated aroma generating unit and the length The ratio of the length in the axial direction is determined based on the size of the chamber of the heating type fragrance device in which the fragrance cartridge is used. It depends on the size of the heated aroma generating body and the porosity in the cross section perpendicular to the longitudinal direction of the heated aroma generating body. However, the causal relationship between the above and the aroma generating device having the irregular gas flow passage of the present invention is unclear. In order to achieve comfortable suction, there is an appropriate length, and the length in the long axis direction and the length in the short axis direction are The ratio is preferably 10:1 to 700:1. Similarly, the specific length of the approximately rectangular parallelepiped in the longitudinal direction is preferably 10 to 70 mm. I wish.

[0266] Such a heated aroma generating unit having anisotropy in the cross-sectional shape perpendicular to the longitudinal direction is The longitudinal plane in the cross section perpendicular to the longitudinal direction of the adjacent heated aroma-generating substrate is perpendicular to the longitudinal direction of the adjacent heated aroma-generating substrate. In the cross section perpendicular to the longitudinal direction of the adjacent heated aroma-generating substrate, the The frequency of contact with the longitudinal surface is high, and the gas flow path is secured while the filling rate is increased. Cut.

[0267] Furthermore, the aroma generating unit to be heated, which has anisotropy in the cross-sectional shape perpendicular to the longitudinal direction, The longitudinal axis of the cross section perpendicular to the longitudinal direction of the heated aroma-generating substrate is in the tangent direction to the circumference of the heated aroma-generating body. The number of heated aroma-generating substrates arranged in the long axis direction is larger than the number of heated aroma-generating substrates arranged in the long axis direction. The number of heated aroma-generating substrates arranged in the normal direction is greater than the number of heated aroma-generating substrates arranged in the normal direction, and the filling rate is increased while ensuring a gas flow path. can be increased.

[0268] Therefore, the aroma cartridge having such a heated aroma generating body is used in a heating aroma device. This allows for comfortable inhalation of the aerosol smoke and aroma, while at the same time reducing the amount of the heated aroma-generating substrate. By increasing the filling rate, the appropriate number of cigarettes can be ensured, and the combustion and This makes it possible to solve the problem of the heated aroma-generating substrate falling off when the aroma cartridge is removed. This makes it easier to insert the aroma cartridge into the heating element provided in the chamber of the heated aroma device. .

[0269] Despite the high packing rate of the heated aroma-generating substrate, the gas flow path was secured. In order to form a heated aroma generating device having a different shaped gas flow path, the following heated aroma generating device is required: The method of production plays an important role.

[0270] That is, the method for producing a heated aroma-generating unit of the present invention is such that the heated aroma-generating sheet The cross-sectional shape cut perpendicular to the length direction is uniform in the length direction and is more than twice as long as the heated aroma generating body. a first step of cutting the noodle-shaped heated aroma-generating substrate into a predetermined amount of the noodle-shaped heated aroma-generating substrate; The heated aroma generating material is then applied to a heated aroma generating material packaging material web of a predetermined width which is supported and conveyed by a belt. A second step of placing the generating material packaging material web so as to be parallel to the longitudinal direction thereof, and bending the belt The noodle-shaped heated aroma-generating substrate is folded into a long piece by folding the heated aroma-generating material packaging material web. A third process is to roll up the rod-shaped heated material in the third process so that it becomes cylindrical. A fourth step of linearly bonding the heated aroma-generating material packaging material web of the aroma-generating material along the longitudinal direction. and a fifth step of cutting the rod-shaped heated aroma generating object produced in the fourth step to a predetermined length. The present invention is characterized in that it comprises:

[0271] The third step of the method for producing a heated aroma generating body is to form a non-circular gas flow path in the heated aroma generating body. In this process, the noodle-shaped heated aroma-generating substrate is heated. The aroma generating objects are aligned in the longitudinal direction and supported and transported by a belt in the aroma generating object packaging section. The noodle-shaped heated aroma-generating substrate is placed on the material web in the longitudinal direction and folded over the belt. The heated aroma generating material is wrapped in a packaging material web, and the heated aroma generating material is wrapped in a long rod-shaped heated The aroma generating body is formed, and the internal structure of the heated aroma generating body is determined. The flow path is formed by the bending of the belt, which allows the noodle-shaped heated aroma-generating substrate to move and collect. The primary aggregates formed by mixing the noodle-shaped heated aroma-generating base material alone and the primary aggregates The secondary aggregates formed by the movement of the bodies generate voids that penetrate the heated aroma generating body. Forming a specially shaped gas flow path, and wrapping the noodle-shaped heated aroma generating substrate alone and its primary aggregates. The mounting member and the heating member form a gap, which forms a non-circular gas flow path passing through the noodle-shaped heated aroma generating body. On the other hand, the higher filling rate is due to the bending of the belt in the later stages of the process. The noodle-shaped heated aroma-generating substrate is rolled up in a wrapping material from a direction perpendicular to its longitudinal direction. The aroma generating body is formed in a cylindrical shape, so the closer it is to the cylindrical shape, the more the aroma generating body becomes. The noodle-shaped heated aroma-generating substrate constituting the primary aggregates and secondary aggregates of the noodle-shaped heated aroma-generating substrate The noodle-shaped heated aroma-generating substrate slides and moves, and the long axis of the cross section perpendicular to the noodle-shaped heated aroma-generating substrate is As the frequency of contact with the major axis of the vertical cross section of the heated aroma-generating substrate increases, The number of noodle-shaped heated aroma-generating substrates arranged with their long axis oriented in the tangential direction to the circumference of the cylinder increases. The packed state of the noodle-shaped heated aroma-generating base material in the outer peripheral region is stable. On the other hand, the central region of the rod-shaped heated aroma generating body is made of the bulky primary structure described above. Since the aggregates and secondary aggregates remain, irregular gas flow paths formed in the primary aggregates and secondary aggregates The porosity of the central region is higher than that of the peripheral region. The heated aroma generating device is a rod-shaped heated aroma generating device having an internal structure formed in this way. The internal structure of the device is identical to that of the device itself.

[0272] That is, the length of the heated aroma generating body in the longitudinal direction is longer than the length of the heated aroma generating body, and the cross-sectional shape is approximately the same. The noodle-shaped heated aroma-generating substrate is then wrapped in a roll of a packaging material web for a heated aroma-generating material in the longitudinal direction. The aroma generating rod is placed on the table and rolled into a cylindrical shape in the longitudinal direction. The flow passage becomes a through hole, and in the process of rolling, the noodle-shaped heated aroma-generating base material forms a cylinder. Therefore, primary and secondary aggregates are generated and form irregular gas flow paths therein. In addition, a different shaped gas flow path can be formed between the packaging material and the primary The agglomerates and secondary agglomerates remain in the central region of the cylindrical rod-shaped heated aroma-generating substrate, but are dispersed in the outer In the peripheral region, the major axis of the vertical cross section of the noodle-shaped heated aroma-generating substrate is aligned with the adjacent noodle-shaped heated aroma-generating substrate. The frequency of contact with the long axis direction of the vertical cross section of the thermal aroma-generating substrate increases, and the tangent line of the circumference of the cylinder The proportion of particles aligned in the direction increases, resulting in a higher filling rate.

[0273] In order to control such behavior, the shape of the noodle-shaped heated aroma-generating substrate is important. The noodle-shaped heated aroma-generating substrate cut in the first step has a cross-sectional length perpendicular to the longitudinal direction and a The aspect ratio of the length of the long axis to the length of the short axis is 1:1 to 30:1. It is preferable that the aspect ratio of the major axis is 40:1 to 3600:1. The aspect ratio of the length of the minor axis to the length of the major axis is preferably 2:1 to 20:1, more preferably 5: It is even more preferable that the aspect ratio is 1 to 20:1. The noodle-shaped heated aroma-generating base material is molded into a cylindrical shape so as to be wrapped in the longitudinal direction and the vertical direction. This is closely related to the mobility of the gas when it is injected, and it is possible to increase the filling rate while securing the gas flow path. Therefore, the aspect ratio of the length of the long axis to the length of the short axis of the cross section perpendicular to the long axis is More than 30:1, and the aspect ratio between the major axis and the minor axis exceeds 3600:1 When the aroma generating noodle is heated, the frequency of contact between the surfaces in the longitudinal direction of the noodle increases, and the mobility of the noodle becomes extremely high. The length of the major axis of the particles is reduced to 0.01 mm, making it difficult to form primary and secondary aggregates. When the aspect ratio of the length of the short axis to the length of the long axis is 1:1, depending on the manufacturing conditions, the noodle-shaped heated In some cases, living organisms may arrange themselves in a close-packed structure.

[0274] The cross-sectional shape of the noodle-shaped heated aroma-generating substrate perpendicular to the longitudinal direction is an isotropic equilateral triangle or square. It is not a problem if the gas flow passage is a regular polygon such as a regular pentagon, or a circle. In forming the shape, it is more preferable that the shape is a rectangle or an ellipse having a short axis and a long axis, Even more preferably, it is substantially rectangular.

[0275] The third step of rolling the noodle-shaped heated aroma-generating substrate of the present invention into a cylinder in the longitudinal direction is carried out by rolling the noodle-shaped noodle-shaped heated aroma-generating substrate into a cylinder in the longitudinal direction. A guide with grooves that can bend the belt into a cylindrical shape in stages is attached to the belt. The packaging material is supported and transported by a roller, and the noodle-shaped heated aroma-generating substrate is placed on the packaging material. The belt is characterized by passing through the paper. If necessary, you can use garniture tape.

[0276] As is clear from the above, in a cross section perpendicular to the longitudinal direction of the rod-shaped heated aroma generating body, When the area of ​​the central region and the area of ​​the peripheral region are equally divided, the central region has a higher porosity than the peripheral region. This state is directly reflected in the heated aroma generating body provided in the aroma cartridge. will be done.

[0277] This is because the noodle-shaped heated aroma-generating substrate, which has anisotropy in the cross-sectional shape perpendicular to the longitudinal direction, is During the process of forming primary and secondary aggregates, The longitudinal plane of the straight cross section is perpendicular to the longitudinal direction of the adjacent noodle-shaped heated aroma-generating substrate. The aroma-generating substrate is heated in a cross section perpendicular to the longitudinal direction of the adjacent noodle-shaped heated aroma-generating substrate, rather than in the cross section perpendicular to the longitudinal direction of the noodle-shaped heated aroma-generating substrate. This is closely related to the increased frequency of contact with the longitudinal plane of the nucleus. In the method, the long axis direction of the cross section perpendicular to the longitudinal direction of the noodle-shaped heated aroma-generating substrate is the same as that of the rod-shaped heated aroma-generating substrate. The number of noodle-shaped heated aroma-generating substrates arranged in the tangential direction of the circumference of the aroma-generating body is greater than the number of noodle-shaped heated aroma-generating substrates arranged in the tangential direction of the circumference of the aroma-generating body in the longitudinal direction. The number of noodle-shaped heated aroma-generating substrates arranged in the normal direction of the circumference of the rod-shaped heated aroma-generating body is greater than the number of noodle-shaped heated aroma-generating substrates arranged in the normal direction of the circumference of the rod-shaped heated aroma-generating body. It is closely related to what you can do.

[0278] The structure of the cross section perpendicular to the longitudinal direction of such a rod-shaped heated aroma generating body is as described above. As mentioned above, the shape of the noodle-shaped heated aroma-generating substrate has a large effect, but the belt conveying speed, It is also possible to control the shape of the guide.

[0279] Further, in order to simplify and facilitate the linear bonding in the longitudinal direction of the packaging member for the heated aroma generating material, In parallel with the process, a predetermined amount of hot melt is applied to a predetermined position of the heated aroma generating material packaging material web. It is preferable to add a step of applying a thermal adhesive and to provide a heating means in the fourth step.

[0280] The method for producing the heated aroma generating body is to continuously produce the heated aroma generating body by the following apparatus: That is, the apparatus for producing a heated aroma generating body of the present invention is capable of producing a heated aroma generating body. A supply device for the noodle-shaped heated aroma-generating substrate formed by cutting a raw sheet, and a packaging member for the heated aroma-generating body A web supply device and an endless belt drive that supports and transports the heated aroma generating material packaging material web. A guide having a plurality of grooves provided on the endless belt conveying path, and a heated aroma generating device. A device for bonding the body packaging material web, and a noodle-shaped heated aroma-emitting substrate for the heated aroma-emitting body packaging material web. The rod-shaped heated aroma generating material wound up in a web is cut by a cutter, and the cutter is continuously driven. Here, the grooves of the multiple guides are arranged in a shape that ranges from a crescent-shaped groove to a half-moon-shaped groove, It has three or four different guides that gradually form a cylinder up to the groove close to the full moon. It is preferable.

[0281] The manufacturing apparatus for a heated aroma-generating body of the present invention includes a bonding step for a packaging member for the heated aroma-generating body. The device for feeding the noodle-shaped aroma-generating substrate to be heated, which is cut from the aroma-generating sheet to be heated, is provided for the purpose of simplifying the above. and a packaging member wafer for a heated aroma generating device on which a predetermined amount of hot melt adhesive is applied at a predetermined position. A feeding device for the heated aroma generating material packaging material web, and a drive device for an endless belt that supports and transports the heated aroma generating material packaging material web. A guide having a plurality of grooves provided on the endless belt conveying path, and a heated aroma generating material envelope. A heating device for the packaging material web, and a noodle-shaped heated aroma-emitting substrate are The rod-shaped heated aroma generating material wound up in a web is cut by a cutter and the cutter is continuously driven. is more preferable.

[0282] The heated aroma generating devices as described above are the heated aroma generating devices illustrated in Figs. In particular, in Figs. 10 to 14, the heated aroma generating device (20, 110) is Fragrance generating body (20), cooling member (40), filter member (50), mouthpiece (60) Examples of various aroma cartridges connected in this order are shown in Figs. 15 and 16. 1 illustrates an example of a fragrance cartridge in which the nozzle is replaced with a filter member (50).

[0283] The cooling area defining member (40) shown in FIG. 10 is adjacent to the aroma generating unit (20) to be heated on the upstream side U. For example, a piece of cardboard rolled into a cylindrical shape with an outer diameter of 5.5 mm and a length of 25 mm. It is.

[0284] The filter member (50) shown in FIG. 10 is adjacent to the cooling area defining member (40) on the upstream side U. The filter member (50) has, for example, an outer diameter of 5.5 mm and a length of 8 mm. It is a cellulose acetate fiber formed into a cylindrical shape.

[0285] The mouthpiece (60) shown in FIG. 10 is adjacent to the filter member (50) on the upstream side U. The mouthpiece (60) is, for example, a cylindrical piece having an outer diameter of 5.5 mm and a length of 8 mm. It is a rolled up piece of cardboard.

[0286] A heated aroma generating unit (20), a cooling area determining member (40), a filter member (50), and The outer diameter of the mouthpiece (60) is preferably 4.7 to 6.1 mm. The heated aroma-generating body having a small outer diameter is a smoking tool that is heated from the periphery of the heated aroma-generating body. This is a device that is preferably used for the main body. The heat obtained from the surroundings is distributed to the entire heated aroma generating unit. This is because the cross section of a smoking article is usually circular, so the "outer diameter" However, if we assume that the cross section is, for example, rectangular, it can be expressed in terms of the perimeter. In this case, the circumferential length is preferably 14.8 to 19.2 mm.

[0287] A heated aroma generating unit (20), a cooling area determining member (40), a filter member (50), and The mouthpiece (60) is packaged in a packaging member (70).

[0288] Note that the dimensions shown in Figures 9-1 and 10 are merely examples, and other dimensions may be used. This is also fine.

[0289] FIG. 11 is a schematic cross-sectional view showing how the aroma cartridge (80) is used.

[0290] The aroma cartridge (80) is attached to a smoking article body (90) when in use. The battery (90) is powered by a battery (not shown) located within the smoking device body (90). The aroma generating unit (20) of the aroma cartridge (80) is heated by the electric power supplied from the The heated aroma generating unit (20) emits an aerosol containing an aroma component. The aerosols generated move from the upstream U side to the downstream D side and enter the mouthpiece. The air is sucked in by the user through the gas (60).

[0291] The aerosol passes through the inside of the cooling area defining member (40), which is a cardboard rolled into a cylindrical shape. That is, the inside of the cooling area defining member (40) cools the aerosol. The cooling area is determined by a cooling area determining member (40). The filter member (50) removes particulate matter contained in the gas inhaled by the user, for example.

[0292] 12 to 16 are schematic perspective views showing modified aroma cartridges.

[0293] One embodiment will be described with reference to the first modified example. FIG. 12 shows a fragrance car according to the first modified example. 1 shows a schematic perspective view of a cartridge.

[0294] The aroma cartridge according to the first modification is the aroma cartridge (80) in the embodiment. The filter member (50) is disposed at a corresponding position of the packaging member (70). A plurality of holes (ventilation areas) (50a) are formed at equal intervals along the circumferential direction of the inner wall of the inner wall of the exhaust pipe (50). The packaging member (70) is pierced by the filter member (50a), and a recess is formed in the filter member (50). The hole (50a) is formed at a distance of 2 mm from one end of the filter member (50). The number of holes (50a) is, for example, 12 to 36, for example, 24. do.

[0295] The filter member (50) has holes (50a) so that the user can easily absorb the aromatic components. The aerosol contained in the mouthpiece (60) can be inhaled more easily, and the user can When sucking, the aroma remaining in the cooling area defined by the cooling area defining member (40) is The aerosol containing the natural aroma of the base material is cooled together with the outside air flowing in through the holes (50a). The result is finer aerosol particles that are better dispersed in the air inhaled by the user. It is expected that the aerosol generated in this way will be well suited for enjoying the aroma. It is expected that the user will be able to inhale the aerosol containing the aromatic ingredient more easily. This makes it easier to draw and also helps to prevent users from inhaling hot aerosols. This allows you to enjoy the natural fragrance of the fragrance base even more. It comes as an aromatic cartridge.

[0296] One embodiment will be described with reference to the second modified example. FIG. 8 shows the aroma cart according to the second modified example. FIG. 2 shows a schematic perspective view of a ridge.

[0297] In the first modification, the packaging member (70) and the filter member (50) are provided at corresponding positions, as follows: A plurality of holes (50a) are formed at equal intervals along the circumferential direction of the filter member (50). However, in the second modification, the corresponding positions of the packaging member (70) and the cooling area defining member (40) are A plurality of holes (ventilation areas) (50b) are formed at equal intervals along the circumferential direction of the cooling area defining member (40). The hole (50b) is formed in the packaging member (70) and the cooling region defining member (40). The hole (50b) is a through hole that penetrates the cardboard that constitutes the cooling region defining member (40). The holes (50b) are drilled at a distance of 2 mm from the other end. The number of holes (50b) is, for example, 12. ~36, as an example, 24.

[0298] A hole (50b) is formed in the filter member (50), so that the user can When the liquid is sucked from the gas, the liquid that remains in the cooling area defined by the cooling area defining member (40) is sucked from the gas. The aerosol containing the natural aroma of the aroma base material is strongly mixed with the outside air flowing in through the hole (50b). As a result of the agitation and cooling, finer aerosols are released into the air inhaled by the user. It is expected that the aerosol will be well dispersed, and the aerosol generated in this way will be able to enjoy the aroma. It is expected that the product will be better suited to the needs of people who want to consume fragrance-rich foods. This makes it easier to inhale hot aerosols, and also prevents users from inhaling hot aerosols. This allows you to avoid the smell of the fragrance and enjoy the natural fragrance of the fragrance base. It will be an aromatic cartridge that can be used in a variety of situations.

[0299] In another embodiment of the second modified example, the aroma cartridge according to the second modified example has a circular It does not include a mouthpiece (60) made of cardboard rolled into a cylindrical shape. For reference, the mouthpiece area (50m) where the user puts their mouth and inhales is The downstream D region of the filter member (50) is determined. In the second modified example, the length of the filter member (50) made of acetate fiber is 8 mm. However, in another embodiment of the second modified example, it is set to 16 mm.

[0300] In another embodiment of the second modified example, the aroma cartridge according to the second modified example has a circular It does not include a mouthpiece (60) made of cardboard rolled into a cylindrical shape. For reference, the mouthpiece area (50m) where the user puts their mouth and inhales is The cooling area is determined to be a downstream D side area of ​​the filter member (50). (40) is set to 25 mm, but in another embodiment of the second modified example, it is set to 30 to 35 mm. In the embodiment, the thickness is, for example, 31 mm, and the length of the filter member (50) is, for example, 10 mm. The cooling area determining member (40) can be made longer, so that the air can be suctioned more efficiently. Even if this is the case, the advantage is that the natural aroma and flavor of the aromatic base material can be stably obtained.

[0301] One embodiment will be described with reference to the third modified example. FIG. 14 shows a fragrance car according to the third modified example. 1 shows a schematic perspective view of a cartridge.

[0302] The aroma cartridge according to the third modification is the aroma cartridge (80) in the embodiment. The filter member (50) is disposed at a corresponding position of the packaging member (70). A plurality of holes (50a) are formed at equal intervals along the circumferential direction of the packaging member (70). At the corresponding position of the cooling area defining member (40), the cooling area defining member (40) is provided with a A plurality of holes (50b) are formed at equal intervals in the filter member (50a). The hole (50b) is drilled at a distance of 2 mm from one end of the cooling area (50c). The hole is drilled at a position 2 mm away from the other end of the fixing member (40).

[0303] Therefore, when the user inhales through the mouthpiece, the cooling area determining member (40) The aerosol containing the natural aroma of the aroma base material that remains in the cooling area determined by the above-mentioned method is discharged from the hole (50 In addition to being strongly stirred and cooled by the outside air flowing in from the hole (50a), As a result of being cooled by the outside air, the finer aerosol particles are inhaled by the user. The synergistic effect of providing a very good dispersion state in the air is expected, and Aerosols are expected to be very suitable for enjoying aromas. The user can inhale the aerosol containing the aromatic ingredient more easily and it is highly recommended for use by the user. This will further prevent people from inhaling hot aerosols, so the first and second In a modified example, a fragrance cartridge is provided that allows the natural fragrance of the fragrance base material to be further enjoyed. It becomes a jackpot.

[0304] One embodiment will be described with reference to the fourth modified example. FIG. 15 shows a fragrance car according to the fourth modified example. 1 shows a schematic perspective view of a cartridge.

[0305] The aroma cartridge according to the fourth modification is made of cardboard rolled into a cylindrical shape in the embodiment. The mouthpiece area that the user places their mouth on and inhales through is not included. The region (50m) is determined to be a downstream D-side region of the filter member (50). The filter material is made of cellulose acetate fiber formed into a cylindrical shape. 50) has a length of, for example, 16 mm.

[0306] The aroma cartridge according to the fourth modification includes heated aroma generating units (20) arranged adjacent to each other in sequence. , a cooling area defining member (40) and a filter member (50). It has a cylindrical appearance with an outer diameter of 5.5 mm and a length of 83 mm.

[0307] The mouthpiece (60) is made of cardboard rolled into a cylindrical shape. If the filter member (50) is used instead, the number of parts required to manufacture the aroma cartridge will be reduced. , the number of assembly steps can be reduced.

[0308] In another embodiment of the fourth modified example, the cooling area defining member (40) is 31 mm, In one embodiment, the length of the filter member (50) is set to, for example, 10 mm. Since the zone defining member (40) can be made long, the fragrance base material can be absorbed even if a large amount of air is inhaled. It has the advantage of being able to consistently obtain natural aroma and flavor.

[0309] In another embodiment of the fourth modified example, the cooling area determining member (40) is 10 to 15 mm For example, the cooling area defining member (40) is 14 mm, In one embodiment, the length of the filter member (50) is, for example, 27 mm. By shortening the area defining member (40), the natural aroma and taste of the aroma base material can be obtained from the first smoking action. The advantage of this method is that it provides sufficient

[0310] One embodiment will be described with reference to the fifth modified example. FIG. 16 shows a fragrance car according to the fifth modified example. 1 shows a schematic perspective view of a cartridge.

[0311] The aroma cartridge according to the fifth modification is the aroma cartridge according to the fourth modification, The filter member (50) is inserted into the packaging member (70) at a corresponding position on the filter member (50). This differs from the fourth modified example in that a plurality of holes (50a) are formed at equal intervals along the circumferential direction. The hole (50a) is formed near the end portion on the cooling region defining member (40) side. As a result, the packaging member (70) is pierced and a recess is formed in the filter member (50). The hole (50a) is drilled at a position 2 mm away from one end of the filter member (50). The number of the holes 50a is, for example, 12 to 36, and in one example, 24.

[0312] The filter member (50) has holes (50a) so that the user can easily absorb the aromatic components. This makes it easier to inhale the aerosol contained in the container, and also allows the user to inhale through the mouthpiece. When the cooling area is cooled, the top of the fragrance base material that remains in the cooling area defined by the cooling area defining member (40) is cooled. The aerosol containing the natural fragrance is cooled together with the outside air flowing in through the hole (50a). This allows finer aerosol particles to be better dispersed in the air inhaled by the user. It is expected that the aerosol generated in this way will be well suited for enjoying the aroma. It is expected that users will find it easier to inhale the aerosol containing the aromatic ingredients. This will further reduce the risk of users inhaling hot aerosols. This will allow you to enjoy the natural fragrance of the fragrance base even more. Become a trudge.

[0313] The mouthpiece (60) is made of cardboard rolled into a cylindrical shape. If the filter member (50) is used instead, the number of parts required to manufacture the aroma cartridge will be reduced. , the number of assembly steps can be reduced.

[0314] In another embodiment of the fifth modified example, the cooling area defining member (40) is 31 mm, In one embodiment, the length of the filter member (50) is set to, for example, 10 mm. Since the zone defining member (40) can be made long, the fragrance base material can be absorbed even if a large amount of air is inhaled. It has the advantage of being able to consistently obtain natural aroma and flavor.

[0315] Furthermore, as another embodiment of the fifth modified example, the cooling area determining member (40) is set to a value of 10 to 15 mm. For example, the cooling area defining member (40) is 14 mm, In one embodiment, the length of the filter member (50) is, for example, 27 mm. By shortening the area defining member (40), the natural aroma and taste of the aroma base material can be obtained from the first smoking action. The advantage of this method is that it provides sufficient

[0316] As shown in Figs. 15 and 16, in the aroma cartridges according to the fourth and fifth modified examples, The length of the cooling area determining member (40) is 25 mm, and the length of the filter member (50) is 16 mm. However, the lengths of the cooling area defining member (40) and the filter member (50) may be changed as appropriate. For example, the length of the cooling area defining member (40) and the length of the filter member (50) The total length of the cooling area determining member (40) is set to 10 to 35 mm, and the total length is set to 41 mm. The length of the filter member (50) can be set to 6 to 31 mm, etc. It is also possible to set the length of the region defining member (40) to 10 mm or more. If the length of the material (40) is 10 mm or more, sufficient cooling capacity can be ensured.

[0317] When the length of the cooling area determining member (40) is 10 mm or more and less than 15 mm, the first smoking The advantage of this is that the natural aroma and flavor of the fragrance base material can be fully obtained from the operation, and it can be used for 15 to 30 m. At m, the natural aroma and flavor of the aroma base material can be obtained stably during the smoking action after the initial smoking. When the diameter is over 30mm, the natural aroma and flavor of the fragrance base material is not lost even if the inhalation is strong. However, if it is more than 30mm, it is preferable to keep it at 45mm or less. The length of the cooling area defining member (40) is preferably 45 mm or less, and more preferably 35 mm or less. If the distance is less than 35 mm, a preferable cooling state can be obtained, and if the distance is less than 35 mm, a more preferable cooling state can be obtained. Because we get:

[0318] The position where the hole (50a) is drilled in the filter member (50) is determined by the filter member ( When the filter is provided within 4 mm from one end of the filter (50), the outside air flowing in from the hole (50a) As a result of the cooling of the air, finer aerosol particles are released into the air that the user inhales. It is easy to achieve good dispersion, and if placed within an area of ​​2.5 mm, it is even more effective. This is preferable because it is possible to achieve this state.

[0319] The position where the hole (50b) is drilled in the cooling area defining member (40) is determined by the cooling area defining portion (40b). When the hole (50b) is provided in a region within 4 mm from the other end of the material (40), the water that flows in through the hole (50b) As a result of being strongly mixed and cooled by the outside air, finer aerosols are inhaled by the user. The nozzle should be located within 2.5 mm of the other end, so that the nozzle can be more easily dispersed during intake. This is preferable because it is possible to more effectively achieve a well-dispersed state.

[0320] Although the present invention has been described above with reference to the embodiments and modifications, the present invention is not limited to these. For example, in the embodiment and the modified example, the length is 42 mm, the width is 1.5 mm, and the thickness is A rectangular heated aroma-emitting substrate (10) of 0.3 mm in diameter was used. A heated aroma-emitting substrate in the shape of a strip of 4 mm, 0.5 to 3.0 mm wide, and 0.1 to 0.5 mm thick In the case of rod-shaped, the length is 20 to 54 mm and the outer diameter is 0.2 to 3. It is possible to use a heated aroma-emitting substrate with a thickness of .0 mm. The length of the strip or rod-shaped filler may be 34 mm or more, but not more than 50 mm. It is also preferable that the length of the strip or rod is 34 to 50 mm. When the filling material, which is in the form of a liquid, is heated in the smoking device body, it emits an aerosol containing the aromatic components of the aromatic base material. This is preferable because it is easy to grow.

[0321] Furthermore, the heated aroma-generating base material contains an aroma base material that is the source of the aroma and an aerosol former. The fragrance base material that is the source of the fragrance is contained in an amount of 30% by mass or more and 90% by mass or less, and The heated aroma generating substrate contains 5% by mass or more and 40% by mass or less of an aerosol former. The heated aroma generating unit contains 0.12 g or more of the aroma base material that is the source of the aroma, and When the aerosol former is composed of 0.02 g or more, the natural fragrance base material It is possible to provide an aroma cartridge that allows the user to enjoy the aroma.

[0322] In this specification, the term "rod-shaped heated aroma-generating substrate" refers to a substrate having a longitudinal direction. The aroma-generating substrate to be heated has a cross section perpendicular to the longitudinal direction that is a perfect circle or ellipse. In addition, in the case of a "rod-shaped heated aroma-generating substrate," the "outer diameter" refers to the diameter of a rod having a cross section of a perfect circle. In the case of an elliptical shape, the length of the major axis is referred to as the diameter. In the specification, even if the cross section perpendicular to the longitudinal direction is polygonal, it is considered to be a "rod-shaped load "Thermal aroma emitting substrate" and the polygon has the largest diameter among one or more circles circumscribing the polygon. The diameter of the circumscribing circle is the "outer diameter."

[0323] In the embodiment and the modified example, the aroma-generating substrate (10) to be heated is wrapped in a packaging material (30). The aroma generating unit (20) to be heated was wrapped in a wrapping material (70). The aerosol may also be wrapped in a packaging material (30) to stabilize the aerosol airflow. This makes it easier for users to inhale the aromatic ingredients.

[0324] Furthermore, in the aroma cartridge according to the embodiment and the modified example, the heated aroma generating body (20) A lid may be placed on the upstream side U of the heating unit 10. This prevents the aroma from diffusing from the heated aroma-generating substrate 10. This can suppress the loss of aroma, and also prevents the aroma cartridge from being heated when it is transported. The lid can prevent the raw substrate (10) from falling out of the aroma cartridge. The aroma generating unit (20) can be made of a material such as paper, sponge, etc. It is also possible to place it on the flow D side.

[0325] The first and second binders may also serve as a fragrance base material that is the source of the fragrance.

[0326] Furthermore, in the embodiment, the heated aroma generating unit (20), the cooling area defining member (40), The filter member (50) and the mouthpiece (60) are arranged adjacent to each other in this order, and a cigarette paper or the like is placed on the filter member (50) and the mouthpiece (60). The aroma cartridge was manufactured by wrapping the packaging member (70) in a cylindrical shape. The member (70) includes a heated aroma generating unit (20), a cooling area defining member (40), and a filter. The member (50) and the mouthpiece (60) are inserted in this order to manufacture the device. It is also possible to manufacture the product by wrapping some of the components in the packaging material (70) and then inserting the remaining components. As an example, a fragrance cartridge according to a fourth modified example (see FIG. 15) The heated aroma generating body (20) is 42 mm long, and the cooling area determining member (40) is 25 mm long. ) is wrapped in a wrapping material (70) having a length of 83 mm, and then a filter material (5 0) can be inserted to manufacture the product.

[0327] In the manufacture of the aroma cartridge according to the embodiment, the aroma generating body (20) to be heated ( Length 42mm), cooling area determining member (40) (length 25mm), filter member (50) (length 8 mm) and mouthpiece (60) (length 8 mm) are The length of the packaging material (70) is 83 mm, but the sum of the lengths of these materials is shorter than the sum of the lengths of the packaging materials (70). For example, as shown in FIG. 17, the mouthpiece (6 0) (length 8 mm), filter member (50) (length 8 mm), and cooling area determining member (40) A wrapping part (25 mm long) long enough to cover the entirety of the aroma generating unit (20) and part of the aroma generating unit (20) to be heated. The fragrance cartridge can be manufactured by wrapping the material (70).

[0328] In addition, in the embodiment, a plurality of rectangular heated aroma-emitting substrates are arranged with their longitudinal directions aligned. In the aroma cartridge according to the modified example, for example, when it is attached to the smoking article body, it is heated. The heated aroma-generating substrate (10) included in the aroma-generating unit (20) breaks, causing problems in use. In order to make the aroma-generating substrate (10) less likely to break, When the aroma-generating substrate (10) is in the form of a strip, nine or more strips are attached to the aroma-generating body (20) to be heated. In the case of rod-shaped pieces, it is preferable that the heated aroma generating unit (20) includes 15 or more pieces. .

[0329] The length of such rod-shaped or strip-shaped filler is determined based on the length of the heated aroma generating unit (20). If it is substantially equal to, it will be more difficult to break.

[0330] It will be obvious to those skilled in the art that various other modifications, improvements, combinations, etc. are possible.
