Detailed Description
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In addition, the following schematically shows a range that needs to be described in order to achieve the object of the present invention, and a part that needs to be described in the present invention is mainly a range that needs to be described, and a part that is not described is a known technology. In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant description is omitted. In addition, the dimensional ratio in the drawings is exaggerated for convenience of explanation and may be different from the actual ratio.
FIG. 8 is a flow chart [ connection ] showing a process [ mode ] of a method [ apparatus ] for producing a heated aroma-generating substrate using an aroma substrate composition according to an embodiment of the present invention. Hereinafter, the manufacturing method of each process will be mainly described. However, we have clearly identified such a manufacturing apparatus: by providing means for performing each step, the overall manufacturing method can be implemented. Therefore, we will describe them as "process [ means ]" and "method [ means ]" at the same time, not to repeat the description of the manufacturing method and manufacturing apparatus. Further, the production method [ apparatus ] described below is a preferable example, and the production method [ apparatus ] of the aromatic base material composition and the heated aromatic base material in the present invention is not limited to the following embodiment.
The manufacturing method [ device ] has a drying/pulverizing step [ mode ] (A) for drying/pulverizing the aromatic base material (as the aromatic generation source) and the like. When the raw material can be used as it is, such a step [ mode ] can be omitted. The method further comprises a preparation step [ mode ] (B) of pretreating and weighing other materials as required when producing the aromatic base material composition and the heated aromatic base material.
After the drying/pulverizing step [ mode ] (A) and the preparation step [ mode ] (B), the resultant is subjected to a mixing step [ mode ] (M) under a predetermined condition to obtain a heated aroma-generating substrate.
The heated aroma-generating substrate can be formed into a desired shape through a filler-forming process [ mode ] (F). The heated aroma generating substrate formed into a desired shape is subjected to an aroma cartridge manufacturing process [ mode ] (G) to be formed into an aroma cartridge.
Hereinafter, the respective steps [ modes ] of the method [ apparatus ] for producing an aromatic base material composition, the method [ apparatus ] for producing a heat-receiving aromatic base material, and the method [ apparatus ] for producing an aromatic cigarette pack will be described in order. The details of the aromatic base material (as a raw material) will be described later.
First, in the drying/pulverization step [ mode ] (a), the part of the aromatic base material to be used (for example, leaves, seeds, dried fruits, stems, barks, roots, etc.) is processed into a desired pulverized material to prepare an aromatic composition. At this time, it is also recommended to adjust the moisture amount to an amount that facilitates absorption or adsorption of the aerosol-forming agent, water, and other components that are added later.
The drying temperature is preferably controlled to 60 ℃ or higher and 80 ℃ or lower. Drying at this temperature range makes it possible to easily achieve a desired moisture content while avoiding the escape of a desired flavor component. The temperature is 65 ℃ or higher, and the desired moisture content is more easily reached, while the temperature is 75 ℃ or lower, and dissipation of the desired flavor component can be further prevented.
The water content of the dried and pulverized product after drying and pulverization is preferably controlled to 5 mass% or less. In this way, the subsequent step [ means ] can be easily slurried. The water content is more preferably controlled to 3 mass% or less. When the water content is controlled to 0.1 mass% or more, the compatibility with water and the like can be maintained in a good state, and therefore, it is recommended to use such a water content.
Then, a sieving step is provided, and the dried and pulverized product obtained in the drying/pulverizing step [ mode ] (a) is sieved so that the aromatic base material composition and the like are fed to the mixing step [ mode ] (M) with a desired particle size.
In the preparation process [ mode ] (B), materials required for producing the aromatic base material composition and the heated aromatic generation base material were prepared and weighed. The preparation process [ mode ] includes the process [ mode ] (B1), the process [ mode ] (B2) and the process [ mode ] (C). The step [ mode ] (B1) is a step [ mode ] in which cellulose (1 st binder) to be used is prepared as necessary and is optionally performed. The step [ mode ] (B2) is a step [ mode ] of preparing a polysaccharide (2 nd binder) before the following 2 nd mixing step (M2). The process [ mode ] (C) is for producing an aerosol. The step [ mode ] (E) is a step [ mode ] in which, when the aromatic base composition is produced, a flavor additive, a preservative, and the like are prepared as necessary and are optionally performed.
The mixing step [ mode ] (M1) is divided into a 1 st mixing step [ mode ] (M1), a curing step [ mode ] (Y) and a 2 nd mixing step [ mode ] (M2). In the 1 st mixing step [ mode ] (M1), the respective materials prepared in the above-mentioned drying/pulverizing step [ mode ] (a), step [ mode ] (B1), step [ mode ] (C) and step [ mode ] (E) are mixed to obtain a 1 st mixture. The 1 st mixture is cured in the curing step [ mode ] (Y), and the 2 nd mixture (aromatic base material composition) is obtained by adding a polysaccharide (2 nd binder) to the 1 st mixture and mixing in the 2 nd mixing step [ mode ] (M2). In the 2 nd mixing step [ mode ] (M2), a flavor additive, a preservative, and the like may be added in addition to the polysaccharide (the 2 nd binder).
The 2 nd mixture (aromatic base material composition) can be formed into a desired shape through a filler forming process [ mode ] (F). Then, the aromatic cigarette pellet is subjected to the aromatic cigarette pellet production process [ mode ] (G) as a heated aromatic base material to obtain an aromatic cigarette pellet. The present invention is described by dividing the present invention into a plurality of steps [ modes ], and these steps [ modes ] may be performed simultaneously or in parallel as necessary. For example, in the above description, the materials prepared in the step [ mode ] (B1) and the step [ mode ] (C) were premixed before the 1 st mixing step [ mode ] (M1), but the present invention is not limited thereto, and the materials prepared in the step [ mode ] (a), the step [ mode ] (B1), the step [ mode ] (C) and the step [ mode ] (E) may be mixed in the 1 st mixing step (M1) at the same time.
The heated aroma-generating substrate of the present invention comprises an aerosol former. As the aerosol forming agent, glycerin, propylene glycol, sorbitol, triethylene glycol, lactic acid, glycerol diacetate (glycerol diacetate), glycerol triacetate (glycerol triacetate), triethylene glycol diacetate, triethyl citrate, isopropyl myristate, methyl stearate, dimethyl dodecanedioate, dimethyl tetradecanedioate, and the like can be used, and glycerin and propylene glycol are particularly preferably used. The aerosol-forming agent may be used alone or in combination of two or more.
The content of the aerosol forming agent in the heated aroma-generating substrate is preferably controlled to be 1 mass% or more and 80 mass% or less, more preferably 10 mass% or more and 40 mass% or less, and most preferably 20 mass% or more and 35 mass% or less, based on the total amount of the heated aroma-generating substrate.
Further, the content of the aerosol former in the heated aroma-generating substrate is preferably controlled to be 30 parts by mass or more and 100 parts by mass or less, and more preferably 50 parts by mass or more and 80 parts by mass or less, with respect to 100 parts by mass of the aroma-generating substrate.
At the same time, it is recommended to use flavor additives to increase the flavor as needed. Examples of the flavor additive include peppermint, cocoa, coffee, black tea extract, xylitol, and the like. And food preservatives (e.g., sorbic acid, potassium sorbate, benzoic acid, sodium benzoate, etc.) may be added as necessary. These components may be used alone or in combination of two or more.
As an embodiment of the present invention, microcrystalline cellulose may be added to the heated aroma generating substrate.
Microcrystalline cellulose is obtained by partially depolymerizing alpha-cellulose obtained from pulp of fibrous plants with an acid, removing soluble fractions, and appropriately crystallizing insoluble fractions, and is different from cellulose used as a binder or thickener described below.
Through various studies, heated aroma-generating substrates (including aroma substrates, aerosol formers, and microcrystalline cellulose) are known as follows. That is, when the heated aroma generating substrate is left under dry conditions, the cellulose crystallites retain their structure and inhibit structural changes such as volume shrinkage, even if they are in a dehydrated state. This effect is thought to be obtained by using microcrystalline cellulose.
In one embodiment of the present invention, microcrystalline cellulose is weighed in the preparation step [ mode ] (B), and then charged into the mixing step [ mode ] (M). The microcrystalline cellulose may be directly supplied to the mixing step [ mode ] (M) as a powder or may be dispersed in a solvent such as water as a suspension. Here, the microcrystalline cellulose may be dispersed in the solvent using a high-speed stirrer, a high-pressure homogenizer, or the like.
The content of the microcrystalline cellulose in the heated aromatic generation base material is preferably controlled to be 1 mass% or more and 15 mass% or less, more preferably 3 mass% or more and 12 mass% or less, and most preferably 5 mass% or more and 10 mass% or less, based on the total amount of the heated aromatic generation base material.
By adding microcrystalline cellulose, the moldability of the heat-sensitive aromatic base material can be improved, the processability (for example, when the components are kneaded by a roll mill) can be improved, and the shrinkage and volume change of the heat-sensitive aromatic base material can be effectively suppressed. Therefore, the addition of microcrystalline cellulose is also effective from the viewpoint of quality control of the aromatic cigarette cartridge and uniformity of use feeling.
The average particle size of the microcrystalline cellulose used in the present invention is preferably controlled to 30 μm or more and 200 μm or less, more preferably 50 μm or more and 150 μm or less, and most preferably 70 μm or more and 120 μm or less. When the average particle diameter of the microcrystalline cellulose is 30 μm or more, the effect of suppressing the shrinkage of the heat-sensitive aromatic generating substrate is excellent, and when it is 200 μm or less, the moldability of the heat-sensitive aromatic generating substrate can be improved in addition to the effect of suppressing the shrinkage of the heat-sensitive aromatic generating substrate.
The average particle size of the microcrystalline cellulose can be determined by a sieving method. The average particle diameter can be determined by JIS K0069: 1992, the procedure described in the publication. The results of the tests on the plurality of sieves are, for example, a total of the masses from sieves having a large mesh size, and it is found that the average particle diameter corresponds to 50% of the mass.
In the microcrystalline cellulose, the amount of the oversize residue having a mesh opening of 250 μm is preferably 8% by mass or less based on the total amount of the microcrystalline cellulose, and the amount of the oversize residue having a mesh opening of 75 μm is preferably 45% by mass or more based on the total amount of the microcrystalline cellulose.
When the amount of the residue on the sieve having a mesh opening of 250 μm is 8% by mass or less, the microcrystalline cellulose can more easily exhibit the effect of suppressing the shrinkage of the base material due to the heated aroma. When the on-screen residue having a screen aperture of 75 μm is 45% by mass or more, the microcrystalline cellulose can more easily exhibit the effect of improving the formability of the heated aromatic base material.
The mass average molecular weight (Mw) of the microcrystalline cellulose is preferably controlled to 10,000 or more and 200,000 or less. When the mass-average molecular weight is 10,000 or more, the effect of suppressing the shrinkage of the base material due to the heated aroma is excellent. When the mass-average molecular weight is 200,000 or less, moldability can be further improved in addition to the above effect of suppressing shrinkage. The mass average molecular weight is more preferably controlled to 20,000 or more and 60,000 or less.
The molecular weight of cellulose can be determined by Gel Permeation Chromatography (GPC). For example, the measurement method described in Japanese patent laid-open No. 6-109715 is employed, and a standard sample of polyethylene glycol or the like is used as appropriate.
As one embodiment of the present invention, menthol and polyvinyl pyrrolidone (a water-insoluble cross-linked polymer) are added to a heated aroma generating substrate.
When menthol and polyvinyl pyrrolidone are contained, menthol, lower alcohol, and polyvinyl pyrrolidone (water-insoluble crosslinked polymer) are weighed in the preparation process [ mode ] (B), and then the weighed menthol, lower alcohol, and polyvinyl pyrrolidone are mixed to obtain a menthol solution, where menthol, lower alcohol, and polyvinyl pyrrolidone are mixed and dissolved. It is recommended to add polyvinylpolypyrrolidone after dissolving menthol in a lower alcohol.
Here, menthol is not limited to being obtained from natural products, and may be a synthetic product. Additionally, mint, peppermint oil, and other menthol-containing materials may also be used. The lower alcohol is a solvent for dissolving menthol, and ethanol is particularly recommended.
In the present invention, the water-insoluble crosslinked polymer means a substance obtained by crosslinking a water-soluble substance of a water-insoluble crosslinked polymer to a water-insoluble substance which swells in water. Of course, the present invention recommends using a substance that does not dissolve but swells in the lower alcohol. It is considered that such a water-insoluble crosslinked polymer (for example, polyvinylpolypyrrolidone or the like) has a hydrophilic portion which contributes to swelling and a hydrophobic portion which is oriented toward menthol to thereby suppress the dissipation of menthol.
As an example of the heated aroma generating substrate in the present invention, it is recommended to use polyvinylpyrrolidone (as a water-insoluble crosslinked polymer) as a crosslinked product of polyvinylpyrrolidone. When polyvinyl pyrrolidone is contained, the heated aroma-generating substrate in the present invention may contain a water-insoluble crosslinked polymer other than polyvinyl pyrrolidone to serve as the water-insoluble crosslinked polymer. Examples of the water-insoluble crosslinked polymer include crosslinked polysaccharides obtained by crosslinking water-soluble polysaccharides. The cross-linked polysaccharide may be a polysaccharide cross-linked by epoxy, ester, ether, or the like.
As another preferred example of the heated aroma-generating substrate, the above-mentioned other water-insoluble crosslinked polymers may be used instead of the polyvinylpolypyrrolidone. Examples of the other water-insoluble crosslinked polymer include crosslinked polysaccharides which are obtained by crosslinking water-soluble polysaccharides. The cross-linked polysaccharide may be a polysaccharide cross-linked by epoxy, ester, ether, or the like.
The amount of menthol added is sufficient as long as the amount targeted for the desired flavor is added. In order to develop the menthol flavor, the content of menthol in the heated aroma-generating base material is 0.1 mass% or more and 10 mass% or less based on the total amount of the heated aroma-generating base material. It is further preferable that the content of the organic compound is controlled to 0.2 mass% or more and 5 mass% or less.
The amount of polyvinylpyrrolidone added to the heated aroma-generating base material is 50 parts by mass or more and 600 parts by mass or less relative to 100 parts by mass of menthol. That is, the content of polyvinylpyrrolidone is 0.5 times or more and 6 times or less with respect to the content of menthol.
In another embodiment of the present invention, the content of polyvinyl pyrrolidone (water-insoluble crosslinked polymer) in the heated aroma-generating substrate is 10 parts by mass or more and 2000 parts by mass or less with respect to 100 parts by mass of menthol. That is, the content of polyvinyl pyrrolidone (water-insoluble crosslinked polymer) is 0.1 times or more and 20 times or less with respect to the content of menthol.
In order to exhibit the effects of the present invention, the content of polyvinylpyrrolidone in the heated aroma-generating substrate is preferably controlled to 2% by mass or more, more preferably 4% by mass or more, relative to the total amount of the heated aroma-generating substrate. By controlling the content, the long-term storage stability can be improved, and the effect of the present invention can be exhibited. The content of polyvinyl pyrrolidone in the heated aroma-generating substrate is within a range of not more than 10 mass% (not more than 10 mass%). When the content is 10% by mass or less, the flavor of polyphenol derived from an aromatic base material can be retained.
The lower alcohol is preferably used in an amount of 50 parts by mass or more based on 100 parts by mass of menthol. Further, when the amount of the lower alcohol is 100 parts by mass or more, menthol can be dissolved and the polyvinyl pyrrolidone can be sufficiently and effectively mixed. When the amount of the lower alcohol used is 2000 parts by mass or less, the residual amount of the lower alcohol can be reduced in the subsequent step [ mode ], and thus the efficient production step [ mode ] can be performed.
In one embodiment of the present invention, the heated aroma-generating substrate preferably contains a polysaccharide. As the polysaccharide, a water-soluble polysaccharide, a water-swellable polysaccharide or a gel polysaccharide is particularly recommended. The use of these polysaccharides may aid in shaping.
In the present invention, as the polysaccharide contained in the heated aroma-generating base material, konjac mannan (glucomannan), guar gum, pectin, carrageenan, locust bean gum and agar can be used. These polysaccharides may be used alone or in combination of two or more. In particular, from the viewpoint of improving moldability, konjac mannan (glucomannan) is recommended as the polysaccharide.
In one embodiment of the present invention, cellulose (1 st binder) is preferably added to the heated aroma-generating substrate containing the polysaccharide. The cellulose contained in the heated aroma generating substrate in the present invention means cellulose, cellulose derivatives and metal salts thereof. As the cellulose, water-soluble cellulose is particularly preferable for binding with the aromatic base material.
As examples of the cellulose in the present invention, methyl cellulose, ethyl cellulose, carboxymethyl cellulose, carboxyethyl cellulose, hydroxymethyl cellulose, hydroxyethyl cellulose, and hydroxypropyl cellulose, and metal salts such as sodium salt, potassium salt, and calcium salt thereof can be used. These celluloses may be used alone or in combination of two or more. In particular, a cellulose-based metal salt is recommended, at least one selected from sodium salt, potassium salt and calcium salt of carboxymethyl cellulose is more recommended, and sodium carboxymethyl cellulose, which is easily available, is especially recommended.
The content of cellulose in the heated aromatic base material is preferably controlled to be 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, further preferably 5 parts by mass or more and 20 parts by mass or less, and most preferably 10 parts by mass or more and 20 parts by mass or less, with respect to 100 parts by mass of the aromatic base material.
When cellulose is contained in the heated aroma-generating substrate, the cellulose is produced in step [ mode ] (E) shown in fig. 8. In this step [ mode ] (E), a component other than cellulose may be further prepared as another 1 st binder. Examples of the 1 st binder other than cellulose include konjac mannan (glucomannan), guar gum, pectin, carrageenan, tamarind gum, gum arabic, soybean polysaccharide, locust bean gum, carrageenan, xanthan gum, and agar. These components may be used alone or in combination of two or more.

The extract of the aromatic base material exemplified above, so-called extract, may also be used, and examples of the form of the extract include liquid, syrup, powder, granule, solution, and the like.
The aromatic base materials may be used alone or in combination of two or more. In the above-described examples of the non-tobacco plant, the dried/pulverized material is not required, and may be directly introduced into the mixing step (M).
Next, the mixing step [ mode ] (M) will be described. As described above, the mixing step [ mode ] (M) includes the 1 st mixing step [ mode ] (M1), the curing step [ mode ] (Y), and the 2 nd mixing step [ mode ] (M2).
An aromatic base material as a raw material is subjected to a drying/pulverizing step [ mode ] (A) and a preparatory step [ mode ] (B), or is directly subjected to a mixing step [ mode ] (M).
In the mixing step [ mode ] (M), the aroma base material, the aerosol former, and, if necessary, microcrystalline cellulose, menthol, polyvinyl pyrrolidone (water-insoluble crosslinked polymer), water, and the like are added and mixed to obtain a heated aroma-generating base material.
When the heated aroma-generating substrate contains polysaccharides and celluloses, it is preferable that the celluloses (1 st binder) are first prepared as necessary in the step [ embodiment ] (B1) shown in fig. 8, then the 1 st mixture is prepared by mixing in the 1 st mixing step [ embodiment ] (M1), then the polysaccharides (2 nd binder) are prepared in the step [ embodiment ] (B2), and the polysaccharides are added as the 2 nd binder in the 2 nd mixing step (M2). Further, it is more preferable to add a curing step [ embodiment ] (Y) of holding the 1 st mixture at a predetermined temperature for a predetermined time (curing) after obtaining the 1 st mixture and before adding the polysaccharide.
It is recommended that cellulose (1 st binder) has a solution viscosity of 300 mPas or more, since it is easily mixed with the aromatic base material. Further, it is recommended that cellulose (1 st adhesive) is favorably bonded (bonded) to an aromatic substrate when the solution viscosity is controlled to 5,000 mPas or more. On the other hand, it is recommended that the solution viscosity of cellulose (1 st adhesive) is controlled to 50,000 mPas or less, and that the adhesive (bonding) strength of the aromatic base material can be easily adjusted when the cellulose is used together with a polysaccharide (2 nd adhesive).
In the present specification, the "solution viscosity" is measured by using a Brookfield viscometer, and is a measured value obtained by preparing an aqueous solution of the component at 1 mass% and then rotating a rotor at 10 to 30rpm (0.17 to 0.5s-1) at 25 ℃ and stabilizing the displayed value.
In the 2 nd mixing step [ mode ] (M), a common mixer can be used. For example, it is recommended to use a method in which the materials in the mixing tank are mixed by applying a shearing force with a stirring blade. Further, the mixing can be further enhanced by kneading using a roll mill, a kneader, an extruder, or the like. In this case, the mixing temperature is preferably controlled to 40 ℃ or lower, more preferably 30 ℃ or lower, and most preferably about 25 ℃. This is because if too high a temperature is applied during the mixing process, it is possible to dissipate the fragrance. And preferably by passing cooling water through the mixing tank to regulate the temperature.
When the heated aroma-generating substrate produced by the curing process [ mode ] (Y) is attached to a smoking device body and smoked, the flavor of the aroma substrate is improved. Particularly, when tea is used as the aroma base material, the effect is remarkable, so that it is recommended. Accordingly, a preferred embodiment of the present invention provides a method for producing a heated aroma-generating substrate, comprising the steps of: a 1 st mixing step [ mode ] (M1) (for mixing an aromatic base material, an aerosol forming agent and cellulose (1 st binder) to obtain a 1 st mixture), a curing step [ mode ] (Y) (for holding the 1 st mixture in a sealed state at a predetermined temperature for a predetermined time), and a 2 nd mixing step [ mode ] (M2) (for adding and mixing a polysaccharide as a 2 nd binder to the 1 st mixture passed through the curing step [ mode ] (Y)).
The temperature in the curing step [ mode ] (Y) is preferably controlled to 15 ℃ or higher and 30 ℃ or lower. This is because the effect of improving the flavor is enhanced at a temperature of 15 ℃ or higher, and the flavor is improved by suppressing the change of the flavor at a temperature of 30 ℃ or lower. It is more preferable to control the temperature to 18 ℃ or higher and 24 ℃ or lower.
The time of the curing step [ mode ] (Y) is preferably controlled to 72 to 336 hours. When the time is 72 hours or more, the flavor is improved, and when the time is 336 hours or less, the change of the flavor is suppressed, thereby maintaining the improvement of the flavor. The time period is preferably 96-192 hours, more preferably 96-168 hours, and most preferably 125-150 hours.
In the curing step [ mode ] (Y), it is preferable to cure the 1 st mixture under a sealed condition. This is to prevent the fragrance from escaping.
In the 2 nd mixing step [ mode ] of adding a polysaccharide (M2), a component other than the above polysaccharide may be further added as another 2 nd binder. Examples of the other 2 nd binder include cellulose, tamarind gum, gum arabic, soybean polysaccharide, carrageenan, xanthan gum, starch, and corn starch. These components may be used alone or in combination of two or more.
The polysaccharide (2 nd adhesive) is preferable because it is suitable for reinforcing the bond between the fragrant substrates when its solution viscosity is more than 50,000 mPa · s. The solution viscosity of the polysaccharide is measured by the Brookfield viscometer described above, and a 1 mass% aqueous solution of the component is prepared, and then the measurement value is measured when the rotor is rotated at 10 to 30rpm (0.17 to 0.5s-1) in an environment of 25 ℃ and the value is stable. And the solution viscosity of the polysaccharide (binder No. 2) can exceed the upper limit of the Brookfield viscometer, namely 100,000 mPas.
When a polysaccharide (2 nd binder) is added to the heated aroma-generating substrate, the heated aroma-generating substrate is easily formed into a desired shape in the next filler-forming step [ mode ] (F). That is, the obtained heated aroma generating substrate has sufficient strength, and moldability is improved. Further, the reason why the addition of the polysaccharide (2 nd binder) in the 2 nd mixing step [ mode ] is preferable is that the mixing becomes easier and the mixture is adjusted to an appropriate hardness more easily than the addition of the polysaccharide in the 1 st mixing step [ mode ]. However, the mixing timing of the polysaccharide (2 nd binder) is not limited to this, and the polysaccharide (2 nd binder) may be mixed in the 1 st mixing step [ mode ].
And the solution viscosity of the polysaccharide (2 nd binder) is preferably larger than that of the above 1 st binder. By selecting such a polysaccharide (binder of the 2 nd class), the processability (moldability) of the heated aroma-generating substrate in the filler molding step [ mode ] (F) is improved. Particularly, glucomannan is recommended because it has good processability (moldability).
The content of the polysaccharide (2 nd binder) in the heated aromatic base material is 0.1-5 parts by mass relative to 100 parts by mass of the aromatic base material. By setting the content as described above, the moldability of the heat-receiving aroma generation substrate can be improved, and a heat-receiving aroma generation substrate which can enjoy the natural aroma and taste of the aroma substrate can be obtained. In addition, relative to 100 parts by mass of the aromatic substrate, the heated aromatic substrate in polysaccharide (2 nd adhesive) content is preferably controlled in 0.2 to 3 parts by mass, more preferably controlled in 0.3 to 1 part by mass.
The mixture obtained above is put into a filler molding step [ mode ] (F) to form a desired filler (heated aroma-generating substrate).
Examples of the molding method used in the filler molding step [ mode (F) ] include a method of forming the aromatic base composition into a rod shape by pressing the aromatic base composition through a hole, a method of molding the aromatic base composition into a sheet and then cutting the sheet, and a method of drying and pulverizing the aromatic base composition to prepare a granular form.
Hereinafter, a method of forming the aromatic base material composition into a sheet and then cutting the sheet will be described in detail. To thin the fragrance base composition, a three-roll mill may be used. When a three-roll mill is used, it is recommended that a sheet having a desired thickness can be formed by a doctor blade while kneading and dispersing the mixture by compression caused by the squeezing between narrow rolls and shearing caused by a difference in roll speed. In addition, it is also recommended to use a press roll or a press for the production.
In addition, in the filling material forming step [ mode ] (F), if necessary, an aromatic base material, an aerosol forming agent, a binder, a thickener, or the like may be added, or a flavor additive, a preservative, or the like may be added, or water or the like may be added.
The water used in the present invention is preferably sterilized or microorganism-removed water, and more preferably pure water obtained by reverse osmosis membrane or ion exchange.
In the step (F) of forming the filler, the thickness of the sheet of the aromatic base material composition obtained is preferably 0.1 to 1.0mm, more preferably 0.1 to 0.5 mm. The obtained sheet is cut into a desired shape, and a cutter, a rotary blade type rotary cutter, or the like can be used for cutting.
As another embodiment of the present invention, the thickness of the sheet of the obtained aromatic base material composition is preferably 0.1 to 1.0 mm.
As a specific example of the filler forming step [ mode ] (F), a heat-sensitive aromatic base material is produced by cutting a sheet of an aromatic base material composition having a thickness of 0.3mm into a desired shape. For example, a sheet of the aromatic base material composition is cut into a rectangular shape having a length of 150mm and a width of 240 mm. The cut sheet was fed to a rotary cutter and cut into a shape of 1.5mm in length and 240mm in width to obtain a cut sheet. The cut 31 sheets were rolled up with cigarette paper to form a roll having an outer diameter of 5.5 mm. The roll was cut into a length of 42.0mm by a cutter, and a heated aroma-generating body having a strip-shaped heated aroma-generating base material was obtained. In this case, the mass of the heated aroma-generating substrate is preferably 0.63 g. When the volume filling ratio is defined as the ratio of the volume of the heat-receiving aromatic generating base material to the volume of the heat-receiving aromatic generator, the volume filling ratio in the above case is 0.59. Thus, the density of the heated aroma-generating substrate, which was calculated from the volume filling rate and the mass of the heated aroma-generating substrate, was 1.07g/cm 3.
As another embodiment of the filling material forming process [ mode ] (F) of the present invention, a sheet of an aromatic base material composition having a thickness of 0.3mm is cut into a desired shape to produce a heated aromatic base material. For example, a sheet of the aromatic base material composition is cut into a rectangular shape having a length of 150mm and a width of 240 mm. The cut sheet was fed to a rotary cutter and cut into a shape of 1.5mm in length and 240mm in width to obtain a cut sheet. The cut 50 sheets were rolled up with cigarette paper to form a roll having an outer diameter of 6.9 mm. The roll was cut into a length of 12.0mm by a cutter to obtain a heated aroma-generating body having a strip-like heated aroma-generating base material. At this time, the mass of the heated aroma-generating substrate was 0.29 g. When the volume filling ratio is defined as the ratio of the volume of the heat-receiving aromatic generating substrate to the volume of the heat-receiving aromatic generator, the volume filling ratio in the above case is 0.60. Thus, the density of the filler calculated from the volume filling ratio and the mass of the heated aroma-generating substrate was 1.07g/cm 3.
The heated aroma generating body obtained in the filling material forming step [ mode ] (F) is in a form in which a plurality of strip-shaped or rod-shaped heated aroma generating substrates are arranged along the longitudinal direction of the aromatic cigarette case. The plurality of strip-or rod-shaped heat-receiving aroma-generating base materials (111 in fig. 3) are wrapped by a wrapping member (151 in fig. 3) such as cigarette paper along the axis of the height of the roll, and become heat-receiving aroma generators (110 in fig. 3).
In the present specification, the "rod-shaped heated aroma-generating substrate" refers to a heated aroma-generating substrate having a shape in the longitudinal direction and a cross section in the direction orthogonal to the longitudinal direction being a perfect circle or an ellipse. In the "rod-shaped heated aroma-generating substrate", the "outer diameter" represents the diameter when the cross section is a perfect circle, and the length of the major axis when the cross section is an ellipse. In the present specification, even when the cross section in the direction orthogonal to the longitudinal direction is a polygon, the cross section is referred to as a "rod-shaped heated aroma generating substrate", and the diameter of a circumscribed circle having the largest diameter among one or more circles circumscribed to the polygon is defined as an "outer diameter".
Therefore, the "strip-shaped heated aroma generating substrate" and the "rod-shaped heated aroma generating substrate" are not strictly distinguished, including the case of both the "strip-shaped heated aroma generating substrate" and the "strip-shaped heated aroma generating substrate".
Next, the process [ mode ] (G) of manufacturing the aromatic cigarette cartridge will be described with reference to fig. 1 as appropriate. The heated aroma generating body (110) obtained in the above-described manner, the support element (300) and the mouthpiece (140) described in detail below are rolled up with the wrapping member (150), or the wrapping member (150) is previously formed into a cylindrical shape, and the mouthpiece (140), the support element (300) and the filler (110) are inserted in this order to produce an aromatic cigarette cartridge.
Therefore, as an example of a preferred structure of the present invention, there is a cigarette cartridge having a heat-receiving aroma generating body (110), a support member (300), and a mouthpiece (140) arranged in this order from an upstream side U to a downstream side D.
The invention can fully exert the following effects: when a user heats the aromatic cigarette cartridge equipped with the heated aromatic generating base material from the periphery of the heated aromatic generating body, the heated aromatic generating base material can be prevented from falling off or falling off from the aromatic cigarette cartridge before and after use even if the heated aromatic generating base material has the following shape. As such a method, a bar-shaped heated aroma-generating substrate having a length of 10 to 70mm, a width of 0.5 to 3.0mm and a thickness of 0.1 to 0.5mm, or a bar-shaped heated aroma-generating substrate having a length of 10 to 70mm and an outer diameter of 0.2 to 3.0mm can be exemplified.
When the heat-generated aroma generation substrate containing microcrystalline cellulose is used, the following excellent effects can be obtained even if it has the above-described shape. That is, the microcrystalline cellulose has good compatibility with other components contained in the heated aroma generating substrate, and thus, mechanical strength and structural stability are improved, and changes in length, width, thickness, and volume of the heated aroma generating substrate with time are reduced. That is, changes in length, width, thickness, and volume over time due to shrinkage or the like of the heated aromatic generation substrate can be effectively suppressed. Therefore, the following effects can be exerted: the moldability of the heated aroma-generating base material is improved, and the processability in kneading with a roll mill or the like is improved.
In addition, even in the case where the above-described shaped heated aroma-generating substrate is formed by adding microcrystalline cellulose having a predetermined particle size according to the present invention to the heated aroma-generating substrate, it is possible to suppress the change with time in the length, width, thickness and volume and to suppress the problem of the heated aroma-generating substrate falling off from the aromatic cigarette bullet during transportation and conveyance. Further, by suppressing the change with time, it is effective in maintaining quality control such as uniformity of feeling of use regardless of the time elapsed after the production.
The preferred shape of the heated aroma-generating substrate is 10 to 70mm in length, 0.5 to 3.0mm in width, and 0.1 to 0.5mm in thickness. Since such a shape has a large surface area, the shape easily draws out the flavor of the aromatic base material when smoking.
In addition, from another aspect of the present invention, the following effects can be sufficiently exhibited: when a user inserts the aromatic cigarette cartridge equipped with the heated aromatic generating base material into the heating element of the smoking device body and uses the cartridge, even if the heated aromatic generating base material is in the shape described below, the heated aromatic generating base material can be prevented from falling off or falling off from the aromatic cigarette cartridge before and after use. As such, a strip-or rod-shaped heated aroma-generating substrate having a length of 10 to 70mm, a width of 0.5 to 3.0mm and a thickness of 0.1 to 0.5mm can be exemplified.
When a heated aroma-generating substrate containing microcrystalline cellulose (the heated aroma-generating substrate referred to in the present invention) is used, the following excellent effects can be obtained even in the form of a strip or a rod having a length of 10 to 70mm, a width of 0.5 to 3.0mm, and a thickness of 0.1 to 0.5 mm. That is, since the microcrystalline cellulose has good compatibility with other components contained in the heated aroma generating substrate, the mechanical strength and structural stability of the heated aroma generating substrate are improved, and the change in length, width, thickness, and volume thereof with time is reduced. That is, changes in length, width, thickness, and volume over time due to shrinkage or the like of the heated aromatic generation substrate can be effectively suppressed. Therefore, the following effects can be exerted: the moldability of the heated aroma-generating base material is improved, and the processability in kneading with a roll mill or the like is improved.
In addition, even in the case where the above-described shaped heated aroma-generating substrate is formed by adding microcrystalline cellulose having a predetermined particle size according to the present invention to the heated aroma-generating substrate, it is possible to suppress the change with time in the length, width, thickness and volume and to suppress the problem of the heated aroma-generating substrate falling off from the aromatic cigarette bullet during transportation and conveyance. Further, by suppressing the change with time, it is effective in maintaining quality control such as uniformity of feeling of use regardless of the time elapsed after the production.
In addition, as another embodiment of the present invention, when a user inserts a cartridge equipped with a heated aroma generating substrate into a heating element of a smoking device body and uses the cartridge, even if the heated aroma generating substrate has the shape described below, the heated aroma generating substrate can be prevented from falling off or falling off from the cartridge before and after use. As such a method, a bar-shaped heated aroma generating substrate having a length of 10 to 70mm, a width of 0.5 to 3.0mm and a thickness of 0.1 to 0.5mm, or a bar-shaped heated aroma generating substrate having a length of 10 to 20mm and an outer diameter of 0.2 to 3.0mm may be mentioned.
When the heat-generated aroma generation substrate containing microcrystalline cellulose is used, the following excellent effects can be obtained even if it has the above-described shape. That is, since the microcrystalline cellulose has good compatibility with other components contained in the heated aroma generating substrate, the mechanical strength and structural stability of the heated aroma generating substrate are improved, and the change in length, width, thickness, and volume thereof with time is reduced. That is, changes in length, width, thickness, and volume over time due to shrinkage or the like of the heated aromatic generation substrate can be effectively suppressed. Therefore, the following effects can be exerted: the moldability of the heated aroma-generating base material is improved, and the processability in kneading with a roll mill or the like is improved.
In addition, even in the case where the above-described shaped heated aroma-generating substrate is formed by adding microcrystalline cellulose having a predetermined particle size according to the present invention to the heated aroma-generating substrate, it is possible to suppress the change with time in the length, width, thickness and volume and to suppress the problem of the heated aroma-generating substrate falling off from the aromatic cigarette bullet during transportation and conveyance. Further, by suppressing the change with time, it is effective in maintaining quality control such as uniformity of feeling of use regardless of the time elapsed after the production.
In one embodiment of the present invention, the heated aroma generating substrate is a strip having a length of 10 to 70mm, a width of 0.5 to 3.0mm, and a thickness of 0.1 to 0.5mm, or a rod having a length of 10 to 70mm and an outer diameter of 0.2 to 3.0mm, and preferably has a length of 10 to 20 mm.
The characteristics of the heated aroma-generating substrate manufactured in the above manner can be confirmed by the following method. That is, the length, thickness and volume of the sheet of the aromatic base material composition before and after drying or the heated aromatic base material were observed.
Specifically, the method comprises drying a sheet of the produced aromatic base material composition or a heated aromatic base material using a halogen moisture meter (electronic halogen moisture meter), measuring the length, width, thickness and volume of the sheet or filler before and after drying, and evaluating the rate of change thereof.
In the present invention, when the moisture content of the sheet of the aromatic base material composition or the heated aromatic base material is 15 to 20% by mass, the length, width, thickness and volume of the sheet of the aromatic base material composition or the heated aromatic base material before drying are measured. To adjust this moisture content, for example, it can be stored at a temperature of 28 ℃ to 30 ℃ in an environment with a relative humidity of about 40% RH to adjust.
The moisture content was measured using a halogen moisture meter (electronic halogen moisture meter) model DHS-50-5 (manufactured by Bangxi Instrument Technology co.ltd.). In the automatic drying mode, the drying temperature was set to 105 ℃, and the moisture content (mass%) was determined from the water loss rate at the end of the automatic measurement. In the automatic measurement mode, the water loss rate is determined by subtracting the mass of the sample at the end of the measurement from the mass of the sample before the measurement and dividing by the mass of the sample before the measurement. The mass change is the moisture content.
The numerical values of the length, width, thickness and volume change rate of the sheet or heated aroma-generating substrate of the aroma substrate composition are obtained by subtracting the numerical values of the length, width, thickness and volume after drying for a certain period of time from the numerical values of the length, width, thickness and volume before drying, and dividing by the numerical values of the length, width, thickness and volume before drying.

In the present invention, it is recommended that the thickness change rate Ta (%) of the sheet of the aromatic base material composition or the heat-sensitive aromatic base material is 1.2% or less because the falling-off of the filler from the aromatic cigarette pack can be more effectively suppressed. The Ta content is more preferably controlled to 1.0% or less, and most preferably controlled to 0.8% or less.

The respective rates of change when the measurement is performed using the sample having the above shape will be described below. An apostrophe is added to each symbol to distinguish it from the use of a 15mm wide, 50mm long, 0.3mm thick sample.

As described above, the aromatic cigarette cartridge (using the heated aroma-generating substrate containing microcrystalline cellulose) of the present invention can suppress the decrease in length, width, thickness, and volume after production over time. In view of this, the aromatic cartridge can also effectively perform the following functions: failure (e.g., detachment of the heated aroma generating substrate from the aromatic cigarette cartridge, etc.) can be reduced; inhibiting changes in aerosol flow properties (which have an effect on the use experience of the aromatic cartridge), and the like; providing a comfortable use experience, maintaining a homogenous material, etc., no matter how long it is left after manufacture.
The characteristics of the heated aroma-generating substrate containing menthol and polyvinyl pyrrolidone (water-insoluble crosslinked polymer) can be confirmed by the following method. Namely, the loss of menthol (contained in the fragrance substrate composition or the heated fragrance-generating substrate) was observed.
In the present invention, the prepared heated aroma-generating substrate was precisely weighed about 5g to 10g in an environment of 17 ℃ and a relative humidity of 65% RH, sealed in a polyethylene bag, and stored at 5 ℃ for 24 hours or 48 hours. After 24 hours or 48 hours had elapsed, the surface of the heated aromatic generation substrate was observed, and the state of precipitation of white crystals was observed. The observation of white crystals means that menthol sublimes and crystallizes from the aforementioned heated aroma generation base material. Subsequently, the heated aroma-generating substrate was precisely weighed to determine the amount of change in mass after being left in a sealed state and left to stand at 17 ℃ under a relative humidity of 65% RH for 3 hours and then opened. By this method, the loss of menthol can be quantitatively measured.
The reason for performing the storage test in an environment of 5 ℃ is that: this condition can suppress the dissipation of other components of the heated aroma-generating substrate, and is suitable for evaluating the dissipation state of menthol. In particular, the following effects are obtained without precipitation of white crystals: the consumer sees the menthol evolved from the aromatic cartridge as it is manufactured, packaged and released to the market for transport/storage without creating an unpleasant feeling.
In the present invention, when the menthol content in the heated aroma-generating substrate after 5g to 10g was precisely weighed in an environment of 17 ℃ and a relative humidity of 65% RH is defined as d (0), the mass of the heated aroma-generating substrate after 24 hours at 5 ℃ is defined as d (24), and the mass of the heated aroma-generating substrate after 48 hours at 5 ℃ is defined as d (48), the menthol reduction rate d is defined as follows.
d＝{(d(24)-d(48)}/d(0)。
Here, in the above formula, the reason for subtracting d (48) from d (24) is that: the dispersion components other than menthol are taken into consideration, and the dispersion components in 24 to 48 hours can better reflect the precipitation of the white crystals.
In the present invention, when d is 0.60 or less, precipitation of white crystals can be suppressed, and therefore, it is recommended to use it. D is preferably controlled to 0.50 or less, more preferably 0.30 or less, and most preferably 0.20 or less.
The above-described aromatic cartridge of the present invention has a relatively large surface area, and thus, easily emits the flavor of menthol when a smoker smokes. Conversely, it can also be said that the aromatic cartridge has a shape that readily sublimes menthol. However, when such a heated aroma-generating substrate containing menthol and polyvinyl pyrrolidone (water-insoluble crosslinked polymer) in the present invention is used, even when the aromatic cartridge has the above-described shape, sublimation of menthol can be effectively suppressed. In addition, in this production process [ mode ], by using a method in which menthol is dissolved in a lower alcohol (ethanol is recommended) in advance, sublimation of menthol can be more effectively suppressed.
Next, the use examples of the prepared heat-sensitive aromatic generating base material will be explained.
Figure 1 is an illustration of one use of the aromatic cartridge. When used by a user, the aromatic cartridge (100) is mounted on the smoking device body (200). The smoking device body (200) is provided with an insertion part (210) for inserting the aromatic cartridge (100).
A heating element (211) is arranged at the central part of the bottom in the insertion part (210), and the heating element (211) is provided with a needle-shaped or blade-shaped component with a sharp front end and is used for being inserted into the heated aromatic generator (110) to heat the heated aromatic generator (110). More specifically, when the aromatic cartridge (100) is inserted into the insertion portion (210) of the smoking device body (200), the heating element (211) is inserted into the central portion of the heated aromatic generator (110).
The heating element (211) directly or indirectly generates heat by electric power supplied from a battery (not shown) provided in the smoking device main body (200). The heated aroma generating body (110) is heated due to the heat energy emitted from the heating element (211), thereby generating an aerosol containing aroma components. In addition, the generated aerosol is transported to the mouthpiece (140) through the support element (300) and the aerosol transport member (130) described below, and then the user inhales from the mouthpiece (140) side, causing the fragrance component to be transported into the user's mouth. Hereinafter, for the purpose of explaining the present invention, the heated aroma generating body (110) side of the aromatic cartridge is referred to as the upstream side U, and the mouthpiece side (140) is referred to as the downstream side D. The upstream side U may be referred to as one end side U, and the downstream side D may be referred to as the other end side D.
Fig. 1 is a schematic view of a heating element (211) having 1 needle-like member or blade-like member, but as another example, a heating element (211) having a plurality of needle-like members or blade-like members may be shown by an exemplary view.
Fig. 2 is a view showing an example of the structure of the cigarette cartridge (100). The aromatic cartridge (100) shown in figure 2 has the following structure: the heated aroma generating body (110), the support element (300), the transport member (130), and the mouthpiece (140) are designed in this order from the side where the heating element (211) is inserted (i.e., from the upstream side U to the downstream side D).
The support member (300) supports the heated aroma generating body (110). The support element (300) is disposed adjacent to the heated aroma generating body (110), and the side portion (160) of the support element (300) is in contact with the wrapping member (150) located at the periphery of the aromatic cartridge (100). And, with respect to the side portion (160), it may be fixed to the inner surface of the packing member (150) with an adhesive, for example.
The support member (300) may be formed using silicone or the like as appropriate, but is not limited to silicone, and other materials having excellent heat resistance may be used.
As shown in fig. 3, it is recommended that the heated aroma generating base material (111) constituting the heated aroma generating body (110) is formed in a bar or rod shape and packed along the longitudinal direction of the shape of the packing (111) at the time of packing. Here, an example of the packing member (151) filled to form a cylindrical shape is shown. As the wrapping member (151), a member obtained by rolling paper (for example, cigarette paper or the like) into a cylindrical shape can be used. In addition, the packing member (150) may also serve as the packing member (151) at the same time. This stabilizes the air flow and allows the user to easily inhale the fragrance component from the heated fragrance generator (110).
Figure 4 is an illustration of one method of manufacturing a cigarette cartridge. Fig. 4 is a schematic structural view in which the heated aroma generating body (110), the conveying member (130), the mouthpiece (140), and the support member (300) exemplified below, which are formed as described above, are sequentially arranged in the order of the heated aroma generating body (110), the support member (300), the conveying member (130), and the mouthpiece (140), and a wrapping member (150) such as cigarette paper is used to form a rod. At this point, the sides (160) of the support element are painted with a small amount of adhesive.
As for the aromatic cartridge (100) having the above structure, for example, the following method can be employed. For example, a packaging member (150) (e.g., a paper tube or the like) having an appropriate inner diameter is prepared, and the inner surface (side portion (160)) thereof is coated with an adhesive. The supporting member (300) is inserted from one end side U of the packing member (150), and then the heated aroma generating body (110) is inserted. The mouthpiece (140) is inserted from the other end side (D). At this time, the transport member (130) may be inserted before the mouthpiece (140) is inserted, if necessary.
Next, a use example of the aromatic cigarette cartridge of the present invention will be described in detail.
As shown in fig. 2, the shape of the aromatic cigarette cartridge (100) is a rod, a cylinder, or the like.
For example, as shown in fig. 2, a heated aroma generating body (110) is provided at one end inside the aromatic cigarette cartridge (100), and a support element (300) and a transport member (130) are provided in this order from the one end to a mouthpiece (140) on the other end side D. Then, they are packaged by using a packaging member (150).
The heated aroma generating body (110) is provided with a heated aroma generating base material. The heated aroma generating body (110) generates an aerosol containing aroma components of plants (raw materials used as heated aroma generating substrates) by heating.
When the heated aroma-generating substrate used for producing the heated aroma-generating body (110) has a shape of a sheet, a strip, a rod, or the like (the long side is about 2 to 20 times the short side) as shown in fig. 3, it is recommended to fill the heated aroma-generating substrate (111) along the longitudinal direction of the cigarette cartridge during filling. This provides good air flow fluidity and facilitates inhalation. Fig. 3 is a view of the end of the aromatic cartridge on the side where the heated aroma generating body (110) is located, and is a partial perspective view in which the filler (111) inside the cartridge can be seen. According to one embodiment of the present invention, the length of the strip-shaped or rod-shaped heated aroma-generating substrate is 10 to 70 mm. In addition, the length of the strip-shaped or rod-shaped heated aroma generation base material is 10-20 mm. Such a length makes handling easy when filling the cartridge.
In another aspect of the present invention, the heated aroma generating substrate having a substantially constant shape, such as a flat plate shape, can be wound up and thus can be easily handled.
From another viewpoint of the present invention, as the shape of the aromatic base material composition sheet, it is recommended to use a shape formed by imparting wrinkles, imparting pleats or folds.
From another perspective of the present invention, the heated aroma-generating substrate of the present invention can be fibrous. As for the fibrous heated aroma generating base material, similarly to the strip-shaped or rod-shaped heated aroma generating base material, the fibrous heated aroma generating base material is packed so that the longitudinal direction of the fibers is along the longitudinal direction of the cartridge, thereby improving the flow condition of the air to be sucked.
From another perspective of the present invention, the heated aroma-generating substrate of the present invention can be porous. The porous heated aroma-generating substrate, when loaded into a cartridge, improves the air flow during smoking. In order to make the heated aroma generating substrate porous, for example, a plurality of needles may be used to pierce the dried sheet a plurality of times, but other methods may be used.
In another aspect of the present invention, the heated aroma-generating substrate according to the present invention may be in the form of a flat plate (e.g., a sheet, a square, a rectangle, a rhombus, etc.), a powder, a granule, or a pellet. The heated aroma generating substrate having such a shape is likely to fall into the opening of the cartridge, and thus the filling is easily completed. In addition, the amount of filling in the cartridge (filling amount) can be finely adjusted, and the air flow condition during smoking can be easily adjusted by the filling amount. The use is facilitated by taking anti-dropping measures (for example, by capping the opening of the cartridge).
From another perspective of the present invention, the block-shaped heated aroma-generating substrate has good thermal conductivity and is apt to promote the release of aroma components. In addition, the size of the block-shaped heated aroma-generating substrate can be increased, and the block-shaped heated aroma-generating substrate can be easily stored. In this case, the large block-shaped heated aroma-generating substrate may be processed into a small block, rod, granule, or the like during filling.
As shown in fig. 2, the support member (300) supports the heated aroma generating body (110). The support element (300) is adjacent to the heated aroma generating body (110), and is provided with a through hole, a notch, and the like for airflow at the center or the side part, so that aerosol generated by the heated aroma generating body (110) can flow to the direction of the cigarette holder (140).
The mouthpiece (140) is provided adjacent to the transport member (130) on the other end side D of the aromatic cartridge (100). In the mouthpiece (140), a filter (e.g., a cellulose acetate filter, etc.) for removing particulates may be designed. The aroma components passing through the filter of the mouthpiece (140) are inhaled by the user.
When the presence or absence of the transport member (130) is compared, it is found that the ventilation property is good when the transport member (130) is not placed, and the smoker easily inhales the generated aroma component. When the transport member (130) is placed, the function is increased (i.e., the generated aerosol can be cooled), and therefore, it is also recommended. At the same time, it is recommended to lengthen the mouthpiece, abutting or contacting the support element (300), instead of increasing the design of the delivery member (130). The reasons for this are: with this configuration, the filter provided in the mouthpiece can simultaneously exhibit a cooling function, thereby reducing the number of components. As the conveying member (130), a hollow tubular member (for example, a member obtained by rolling up a rolled polymer sheet along the longitudinal direction of the aromatic cigarette cartridge) can be used.
Figure 5 is a schematic illustration of a variant of the aromatic cartridge.
Fig. 5 (1) is a schematic view of the structure in which the heated aroma generating body (110) is in contact with the supporting member (300), which can stably support the heated aroma generating body (110), and thus, it is recommended to use this method. In addition to this simple construction, the advantages are also great from the manufacturing point of view.
Fig. 5(2) shows a structure in which a spacing member (180) is provided between the heated fragrance generator (110) and the support member (300), and contact is made by means of the spacing member (180). As the spacer member (180), for example, a filter or paper having good air permeability is used, and it is recommended to use a material which can be easily punctured when the heating element (211) is inserted. Providing such a spacer member (180) can produce the following effects: the heated aromatic generating body (110) is prevented from moving in the aromatic cigarette bullet due to the influence of logistics such as transportation and the like.
FIG. 5(3) is a schematic view showing the structure of the cover (170) on the side of the heated aroma generating body (110) (the side where the heating element (211) is inserted). This configuration is recommended because: the dissipation of the fragrance of the heated fragrance generating body (110) can be prevented. In addition, this configuration can also produce the following effects: the heated aromatic generating body (110) is prevented from falling off from the aromatic cigarette bomb to the outside due to the influence of logistics during transportation and the like. The material of the cover (170) includes: filter tips, paper, sponge, etc. When inserting the heating element, it is recommended to provide 1 or more cuts on the cover (170), or to provide a circular or polygonal guide hole at the position where the heating element is inserted.
From another point of view of the present invention, in the case where a particulate material (for example, powder, granule, flake, pellet, etc.) is used as the heat-sensitive aroma generating base material (filled in the heat-sensitive aroma generating body (110)), it is preferable to provide the spacer member (180) or the cover (170), and it is more preferable to provide both of them.
From another perspective of the present invention, a specific manner of using the aromatic cartridge as an example is as follows. The heated aroma generating body (110) has a substantially cylindrical shape formed by wrapping with cigarette paper or the like, and the diameter of the bottom surface or the upper surface of the substantially cylindrical shape is 6.5 to 7.5mm, and the height of the substantially cylindrical shape is preferably 11.0 to 13.0 mm. The heated aroma generating substrate is preferably in the form of a strip or rod filled along the length of the cartridge, and the heated aroma generating substrate has a length substantially equal to the height of the cylinder, i.e., a length of 11.0 to 13.0 mm.
From another perspective of the present invention, the outer diameter of the support member (300) is substantially equal to the diameter of the substantially cylindrical bottom or upper surface of the heated aroma generating substrate (110). The length of the support element (300) is preferably 9.0-11.0 mm.
From another aspect of the present invention, the length of the mouthpiece (140) is more than 20.0mm, for example, the length is preferably 21.0 to 25.0 mm.
In another aspect of the present invention, the volume filling ratio of the heated aromatic generator is 0.55 to 0.65.
Figure 6 is a schematic view of another use of the aromatic cartridge. Since the aromatic cigarette cartridge has a different structure from the aromatic cigarette cartridge (100), the aromatic cigarette cartridge (500) will be described below. Since there is a part different from the smoking device body (200) in the smoking device body to be used, the smoking device body (400) will be described below.
When the cigarette holder is used by a user, the aromatic cigarette cartridge (500) is mounted on the smoking device main body (400). The smoking device main body (400) is provided with an insertion part (450) for inserting the aromatic cartridge (500). The smoking device body (400) is provided with an outer casing part (410), and the heated aroma generating body (110) of the aromatic cigarette cartridge is heated by a heating part (440) (surrounding the aromatic cigarette cartridge (500)) to generate aerosol, thereby smoking. When smoking is performed from the other end side D, air flows in from the air vent (431), and the generated aerosol passes through the hollow tube member (530), the conveying member (130), and the mouthpiece (140) to smoke. The control unit (420) includes a battery, a control device for the heating unit, and the like. The opening/closing cover (430) is opened when smoking is finished or when the inside of the smoking device main body is cleaned.

In the aromatic cigarette case (500), a heated aromatic generator (110), a hollow tubular member (530), a transport member (130), and a mouthpiece (140) are designed in this order from one end side (U) to the other end side (D), and are wrapped with a wrapping member (150). The heated aroma generating body (110) is partially heated by the smoking device body, and therefore, a hollow tube member (530) is provided for heat insulation. The conveying member (130) can also function as a cooling member at the same time.
The outer diameter of the aromatic smoke cartridge (500) shown in FIG. 7 is preferably controlled to be 4 to 6mm, the length of the heated aromatic generating body (110) is preferably controlled to be 10 to 70mm, and the length of the hollow cylindrical member (530) is preferably controlled to be 20 to 30 mm. The length of the conveying member (130) is preferably controlled to be 5 to 15mm, and the length of the mouthpiece (140) is preferably controlled to be 10 to 25 mm.

For example, the heated aroma generating body (20) has an outer diameter of 5.5mm and a length of 42.0 mm. In one embodiment of the present invention, the length of the heated aroma generating body (20) is more than 20mm, preferably 34mm or more. The length of the heated aroma generating body (20) is preferably 70mm or less, more preferably 54mm or less, and still more preferably 50mm or less. In one embodiment of the present invention, the heated aromatic generating body (20) has a length of 10 to 70mm, preferably 34 to 54mm, and more preferably 34 to 50 mm.
Similarly, in one embodiment of the present invention, the length of the heated aroma-generating substrate (10) is preferably greater than 10mm, and is preferably controlled to be 34mm or greater. The length of the heated aroma generating body (10) is preferably 70mm or less, more preferably 54mm or less, and still more preferably 50mm or less. In one embodiment of the present invention, the heated aromatic generating body (10) has a length of 10 to 70mm, preferably 34 to 54mm, and more preferably 34 to 50 mm.
The heated aroma generating substrate (10) filled into the heated aroma generating body (20) shown in fig. 9-1(B) is formed into a strip shape having a length of 42.0mm, a width of 1.5mm, a thickness of 0.3mm, etc., and is positioned from one end to the other end of the heated aroma generating body (20) in the length direction. As shown in fig. 10, the longitudinal direction of the strip-shaped heated aroma-generating substrate (10) is substantially parallel to the longitudinal directions of the heated aroma-generating body (20), the cooling region determining member (40), the filter member (50), the mouthpiece (60), and the aromatic cigarette cartridge (80). As an example, the heated aroma generating body (20) is a cylindrical member formed by rolling 31 strips of a heated aroma generating base material (10) having a length of 42.0mm, a width of 1.5mm and a thickness of 0.3mm using a packing member (30). For example, the longitudinal direction of the heated aroma generating substrate (10) provided in the packaging member (30) may be substantially parallel to the longitudinal direction of the heated aroma generating body (20).
For example, the volume filling rate of the heated aroma generating body (10) can be set to about 0.60 relative to the volume of the heated aroma generating body (20). The volume fill factor of the heated aroma generating substrate (10) may be considered and determined from the aspects of the intensity of aroma delivered to the user, the ease of inhalation by the user, and the like. The volume filling ratio of the heated aroma-generating substrate (10) is preferably controlled to be 0.55 to 0.65, for example, relative to the volume of the heated aroma-generating body (20).
For example, the heated aromatic generating body (20) may be configured by adjoining the heated aromatic generating substrate (10) having a length of not more than 42.0mm in the longitudinal direction of the heated aromatic generating body (20), or by overlapping a part of both.
However, as can also be seen from FIG. 3, in the heated aroma generating substrate in the heated aroma generating body shown in FIG. 9-1, the heated aroma generating substrate is arranged in a grid-like manner, and it is difficult to exert both of the following effects: the falling off of the base material caused by the heated aroma when the aromatic cigarette bullet is loaded and unloaded is prevented; ensure the air channel is unobstructed when smoking. Accordingly, the present inventors have studied a solution that can fill a heated aroma generating substrate as a heated aroma generator, and have the following advantages: even if the filling rate of the heated aroma generating base material in the heated aroma generating body is increased (after the filling rate is increased, when the aromatic cigarette cartridge is mounted on or dismounted from the smoking device, the heated aroma generating base material cannot fall off or the smoking device cannot burn when the smoking device performs smoking action), the smooth passage of the heated gas can be ensured, the comfortable smoking experience is provided for the smoker, and each aromatic cigarette cartridge is ensured to have proper smoking times.
As a result, it has been found that, while optimizing the shape and size of the heated aroma generating substrate, and the distribution and filling rate of the heated aroma generating substrate within the heated aroma generating body, there is particularly a need for a heated aroma generating body manufacturing method and a corresponding manufacturing apparatus for optimizing the distribution of the heated aroma generating substrate, and thereby a heated aroma generating body (formed by filling the heated aroma generating substrate) having the following characteristics is manufactured: the problem of falling off of the heated aromatic base material and the problem of burning during suction can be solved; ensuring the smooth passage of the gas generated by heating; brings comfortable smoking experience to smokers; ensuring that each aromatic cartridge has the appropriate number of puffs. Hereinafter, the shape of the surrounding heated aromatic generating base material (constituting the heated aromatic generating body), the noodle-like heated aromatic generating base material (serving as a raw material of the heated aromatic generating base material), the method for producing the heated aromatic generating body, and the apparatus for producing the same will be specifically and specifically described. Here, the heated aroma generating body is composed of a heated aroma generating base material, and the noodle-shaped heated aroma generating base material is a raw material for manufacturing the heated aroma generating base material. They will be described explicitly in the following. However, the heated aroma generating substrate is obtained by cutting only the noodle-shaped heated aroma generating substrate, and the chemical compositions of both are the same, so that when referring to both, the present invention will simply express them as "heated aroma generating substrate".
As a specific example, a heat-sensitive aromatic generating substrate having the same cross-sectional shape as that of FIG. 9-1(B) will be described. First, the formed heated aroma generating sheet was cut into a rectangular shape having a length of 150mm and a width of 240 mm. The resulting rectangular heated aroma-generating sheet was fed to a rotary cutter and cut into a shape of 1.5mm in length and 240mm in width to obtain a cut sheet (i.e., a noodle-shaped heated aroma-generating base material (23) for producing a heated aroma-generating body (21)). The noodle-like heated aroma-generating substrate (23) is shown in FIG. 9-2 (B). Here, the minor axis length X of the cross section perpendicular to the longitudinal direction of the noodle-like heated aroma-generating substrate (23) is 0.3mm, the major axis length Y of the same cross section is 1.5mm, the length Z of the longitudinal direction is 240mm, and the aspect ratio of the major axis length to the minor axis length is Y: x is 5: 1, the aspect ratio of the length in the longitudinal direction to the length of the minor axis is Z: x is 800: 1.
however, the planar strip-shaped heated aromatic generating substrate is not limited to the approximately rectangular parallelepiped shape shown in fig. 9-2(B), and a planar strip-shaped heated aromatic generating substrate having an approximately square vertical cross section shown in fig. 9-2(a) (i.e., a planar strip-shaped heated aromatic generating substrate having an aspect ratio of the minor axis length to the major axis length of 1: 1) may be used.
In addition, as shown in FIGS. 9-3(A) and (B), a noodle-shaped heated aroma generating substrate having a circular or oval vertical cross section may be used. However, when the noodle-like heated aroma generating substrate having the above-described vertical sectional shape is used, the following manufacturing method can be adopted: extrusion molding using circular and oval dies, or extrusion noodle making machine.
For example, fig. 9-4 illustrate a method and apparatus for manufacturing a heated aroma generating body (21) in a fragrance cartridge using a 50 root-surface strip of heated aroma generating body (23). Wherein the noodle-like heated aroma generating body (23) has a shape shown in fig. 9-2(B), and Y: x is 5: 1, Z: x is 800: 1. a noodle-shaped heated aroma generating body (23) (formed by cutting a heated aroma generating sheet) is loaded in the length direction of a heated aroma generating body packaging member net (712), continuously wound, rolled into a rod-shaped heated aroma generating body (25), and cut to obtain a heated aroma generating body (21).
The length direction of the noodle-shaped heated aroma generation substrate (23) is kept parallel to the moving direction of the conveyor (81), the noodle-shaped heated aroma generation substrate (23) (formed by cutting a heated aroma generation sheet) is placed on the conveyor (81) of the noodle-shaped heated aroma generation substrate supply part (8), passes through the conveyor (81) and the noodle-shaped heated aroma generation substrate conveying device (82), the length direction of the heated aroma generator packaging member net (712) (supplied by the packaging member supply part (71) of the heated aroma generator) is kept parallel to the length direction of the noodle-shaped heated aroma generation substrate (23), and the noodle-shaped heated aroma generation substrate of the winding part (7) is conveyed to the heated aroma generator packaging member net (712) at the receiving part (730). The heated fragrance generator packaging member web (712) is supported and conveyed by an endless conveyor belt (721) (supplied from a conveyor belt supply part (72)). A strip-shaped heated aroma generating substrate (23) is placed on a heated aroma generating body packaging member web (712) supported and conveyed by this conveyor belt (721), and the conveyor belt (721) is wound around a cylindrical rod-shaped heated aroma generating body (25) together with the heated aroma generating body packaging member web (712) by winding guides (1) to (4) (which are curved from the conveying direction and the vertical direction and are provided with grooves) and cut to a predetermined length at a cutting section (9) to produce a heated aroma generating body (2). Further, a hot melt adhesive is applied in advance to a predetermined position of the heat-receiving fragrance generator packaging member web (712), and after winding, the packaging member of the bar-shaped heat-receiving fragrance generator (25) is linearly bonded in the conveying direction by the heat bonding section (74).
The filling structure (i.e., irregular gas passage) of the heated aroma-generating substrate (21) thus produced, bundled by the heated aroma-generating body packaging member (22) and contained in the heated aroma-generating body (2), is formed in the following manner: a heated aroma generating body packaging member net (712) loaded with a noodle-shaped heated aroma generating base material (23) is formed together with a conveyor belt (721) by winding guides (1) (731) to (4) (734) provided in a winding part (7) and having grooves of different depths.
FIGS. 9-5(A) to (E) show the state of the irregular gas channel formation of the heated fragrance-generating substrate (21) bundled by such a heated fragrance generator-packaging member (22) and contained in the heated fragrance generator (2). The winding guides (1) (731) to (4) (734) have a cross-sectional shape cut perpendicular to the conveying direction, and the depth of the groove becomes deeper in the conveying direction, and finally, complete winding is performed in the winding guides (4) (731).
FIGS. 9 to 5A are schematic views showing the state of conveyance of the noodle-like heated aroma-generating substrate (23). Wherein, under the condition that the length direction of the heated aroma generating body packaging member net (712) (supplied by the heated aroma generating body packaging member supply part (71)) is kept parallel to the length direction of the noodle-shaped heated aroma generating base material (23), the noodle-shaped heated aroma generating base material (23) passes through the heated aroma generating base material conveying device (82) from a conveyor (81), and is conveyed to the heated aroma generating body packaging member net (712) at a heated aroma generating base material receiving part (730) of a winding part (7). Although the actual stacking state does not reach the level shown in fig. 9 to 5(a), the noodle-like heated aroma generating substrates (23) are stacked almost in a regular arrangement.
FIGS. 9 to 5(B) show the state of the noodle-like heated aromatic generating substrate passing through the winding guides (1) (731) like a crescent-shaped groove. When the noodle-shaped heated aroma generating substrate (23) arranged and stacked on the heated aroma generating body packaging member web (712) passes through the grooves together with the conveyor belt (721), the conveyor belt (721) and the heated aroma generating body packaging member web (712) are bent along the grooves in a direction perpendicular to the conveying direction while forming the noodle-shaped heated aroma generating substrate primary aggregate (232), so that the noodle-shaped heated aroma generating substrate (23) is collapsed and the noodle-shaped heated aroma generating substrate primary aggregate starts to be formed to form the gas channel.
Next, FIGS. 9 to 5(C) show the state in which the noodle-like heated aroma generating substrate passes through the winding guides (2) (732) like the half-moon-shaped grooves. The conveyor belt (721) and the heated fragrance generator packaging member web (712) are largely bent along the grooves in a direction perpendicular to the conveying direction, gradually forming noodle-shaped primary aggregates (232) of the heated fragrance generating substrate, and respectively forming a plurality of noodle-shaped primary aggregates of the heated fragrance generating substrate to form gas channels (233). Meanwhile, noodle-shaped heated aromatic generation base material secondary aggregates (234) are formed between the noodle-shaped heated aromatic generation base material primary aggregates (232) or by the noodle-shaped heated aromatic generation base material primary aggregates (232), the noodle-shaped heated aromatic generation base material monomers (231) and the like. And a larger noodle-shaped heated aromatic generation substrate secondary aggregate is formed between the noodle-shaped heated aromatic generation substrate primary aggregate (232) or between the noodle-shaped heated aromatic generation substrate primary aggregate (232) and the noodle-shaped heated aromatic generation substrate monomer (231) to form a gas channel (235). In addition, in the outer peripheral region, gas passages (241) are formed between the noodle-shaped heated aroma generating substrate monomer (231), the noodle-shaped heated aroma generating substrate primary aggregate (232), and the heated aroma generating body wrapper member web (712).
In addition, in fig. 9 to 5(D), when the noodle-like heated aroma-generating substrate (23) passes through the winding guide (3) (733) having a groove of nearly full moon shape, the transport state thereof is changed more greatly than that shown in fig. 9 to 5(C), the conveyor belt (721) and the heated aroma generator packaging member web (712) are wound along the groove in a circumferential pattern in a direction perpendicular to the transport direction, in the outer circumferential region, the noodle-like heated aroma-generating substrate (23) (constituting the primary aggregate (232) of the noodle-like heated aroma-generating substrate and the secondary aggregate (234) of the noodle-like heated aroma-generating substrate) is slidingly moved, the contact ratio of one surface in the major axis direction of the vertical cross section of the noodle-like heated aroma-generating substrate (23) to one surface in the major axis direction of the vertical cross section of the adjacent noodle-like heated aroma-generating substrate (23) is increased, meanwhile, the number of the noodle-shaped heated aroma generating base materials (23) distributed in the circumferential tangential direction in the long axis direction is increased, so that the filling rate of the noodle-shaped heated aroma generating base materials (23) in the peripheral area is increased. On the other hand, the noodle-shaped primary aggregate (232) of the heated aromatic generation substrate and the noodle-shaped secondary aggregate (234) of the heated aromatic generation substrate remain in the central area, the gas channel (233) formed by the noodle-shaped primary aggregate of the heated aromatic generation substrate and the gas channel (235) formed by the noodle-shaped secondary aggregate of the heated aromatic generation substrate are not obviously reduced, and the number of pores is more than that of pores in the peripheral area.
Next, in fig. 9 to 5(E), the conveyor belt (721) and the heated fragrance generator packaging member web (712) are completely wound along the grooves in the direction perpendicular to the conveying direction to form the rod-shaped heated fragrance generator (25). In this state, the state shown in FIGS. 9 to 5(D) is further upgraded to fix the internal structure of the rod-shaped heated aroma generating body (25). That is, in the central region of the rod-shaped heated aromatic generating body (25), there remain the bulky noodle-shaped heated aromatic generating substrate primary aggregate (232) and noodle-shaped heated aromatic generating substrate secondary aggregate (234), and noodle-shaped heated aromatic generating substrate primary aggregate forming gas channel (233) and noodle-shaped heated aromatic generating substrate secondary aggregate forming gas channel (235) exist in their interiors, and therefore, the porosity can be increased, and the smoothness of irregular gas channels can be ensured. In one aspect, a heated aroma generating substrate web forming gas channel (241) is also formed in the peripheral region between the noodle-shaped heated aroma generating substrate monomer (231), the noodle-shaped heated aroma generating substrate primary aggregate (232), and the noodle-shaped heated aroma generating substrate web packaging member (712). However, the noodle-shaped heated aroma generating base material (23) (which constitutes the noodle-shaped heated aroma generating base material primary aggregate (232) and the noodle-shaped heated aroma generating base material secondary aggregate (234)) slides and moves, the contact rate between one surface of the noodle-shaped heated aroma generating base material (23) in the long axis direction of the vertical cross section and one surface of the adjacent noodle-shaped heated aroma generating base material (23) in the long axis direction is increased, and the number of noodle-shaped heated aroma generating base materials (23) distributed in the circumferential tangential direction in the long axis direction is increased, so that the filling rate of the noodle-shaped heated aroma generating base material (23) in the peripheral region is increased, and a stable and firm structure is formed.
The internal structure of the rod-shaped heated aroma generating body (25) has the following characteristics: has a cross section perpendicular to the length direction thereof, and the cross section perpendicular to the length direction of the noodle-shaped heated aroma generating base material (23) is uniform in the length direction, so that the vertical cross-sectional structure of the rod-shaped heated aroma generating body (25) in the length direction is uniform, and at the same time, the noodle-shaped heated aroma generating base material primary aggregate forming gas channel (233), the noodle-shaped heated aroma generating base material secondary aggregate forming gas channel (235) and the heated aroma generating body packaging member network forming gas channel (241) are through in the length direction of the rod-shaped heated aroma generating body (25). Therefore, the internal structure of the heated aroma generating body (2) (which is made by cutting the bar-shaped heated aroma generating body (25)) is substantially the same as that of the bar-shaped heated aroma generating body (25).
FIGS. 9-6 are enlarged views of cross-sections perpendicular to the length direction of the heated fragrance generator (2). This enlarged view is the same as the sectional view in fig. 9 to 5(E), and substantially the same structure is formed in the longitudinal direction. Therefore, when the aromatic cigarette bomb (provided with the heated aromatic generating body (2)) is used for smoking, the problems of the traditional aromatic cigarette bomb can be solved, and the following effects are achieved: the smoke aerosol and the aromatic components are fully inhaled in the oral cavity of a smoker; enjoy a comfortable smoking experience; the heated aroma generating substrate does not fall off when the aromatic cartridge is mounted/dismounted, a proper smoking number can be ensured, and the heated aroma generating substrate does not burn when inhaled (wherein the reason is that the heated aroma generating substrate has a higher filling rate in the peripheral region than in the central region and forms a firm structure under the pressure applied by the end and the peripheral region of the heated aroma generating body). In addition, the filling rate of the central area is low, so that the aromatic cigarette cartridge can be easily inserted into the heating body of the heating type aromatic device.
The heated aroma generating body (2) produced by the present embodiment has the following characteristics: a50-gauge strip-shaped heat-sensitive aroma generating substrate (23) was wound with a heat-sensitive aroma generating body packaging member web (712), cut at a cutting section (9), and processed into a size of about 6.9mm in outer shape and 12.0mm in length, with a mass of 0.29g, a volume filling rate of the heat-sensitive aroma generating substrate (21) of about 0.60 relative to the volume of the heat-sensitive aroma generating body (2), and a density of the heat-sensitive aroma generating body (2) of 1.07g/cm 3. The heated aroma generating body thus manufactured can be applied to the aroma cartridges shown in fig. 1, 2, 4 to 7 and 10 to 17, and is completely suitable for heating type aroma devices circulating in the market.
As above, the following features of the heated aroma generator have been specifically described, but their function is not limited thereto: even if the filling rate of the heated aroma generating base material in the heated aroma generating body is improved (after the filling rate is improved, when the aromatic cigarette cartridge is mounted on/dismounted from the smoking device, the heated aroma generating body cannot fall off, and combustion cannot be caused during inhalation), the smooth passage of the gas generated by heating can be ensured, the comfortable smoking experience is provided for smokers, and each aromatic cigarette cartridge is ensured to have proper smoking times. The heated aroma generator of the present invention includes all the features covered by the following technical ideas.
That is, the heated aroma generator of the present invention has the following features: wherein, the heated aromatic generating substrate is wound by the packaging member, and the heated aromatic generating substrate is provided with three gas channels (a pore gas channel formed by the aggregation of the heated aromatic generating substrate and the primary aggregation, a pore gas channel formed by the aggregation of the heated aromatic generating substrate and the primary aggregation and the secondary aggregation, and a pore gas channel formed by the contact of the heated aromatic generating substrate and the primary aggregation with the packaging member), and the gas channels penetrate through the heated aromatic generating body to form irregular gas channels. The heated aromatic generating body with the irregular gas channel can fully ensure the smoothness of the gas channel, thereby playing the following roles: solving the problem of burning of the heated aromatic generation base material during inhalation; to provide a comfortable inhalation of sufficient amounts of smoke aerosols and aroma components by the smoker; can be easily inserted into the heating body of the heating type fragrance device. On the other hand, the heated aroma-generating substrate has a high packing ratio, so that an appropriate number of puffs can be ensured, and the problem of falling off of the heated aroma-generating substrate does not arise when mounting/dismounting the aromatic cartridge.
In addition, when the central region and the peripheral region are equally divided in cross section in the longitudinal direction of the heated aromatic generator, the central region has a higher porosity than the peripheral region, and such irregular gas passages can exert the above-mentioned effects, so that it is recommended to adopt such a design.
In addition, the longitudinal vertical cross-sectional shape of the heated aromatic generating substrate (constituting the heated aromatic generator) is uniform in the longitudinal direction, and the aspect ratio of the major axis length to the minor axis length of the longitudinal vertical cross-section is controlled to be 1: 1-30: 1 is preferably controlled to be 2: 1-20: 1 is better, and the control is carried out in the following steps of 5: 1-20: 1 is most preferred. However, when the aspect ratio of the length of the major axis to the length of the minor axis is greater than 30: 1, it is difficult to ensure a gas passage.
In addition, as can be seen from the aspect ratio, the sectional shape perpendicular to the longitudinal direction of the heated aroma-generating substrate is not particularly limited, and may be a regular polygon (e.g., equilateral triangle, square, and regular pentagon) or a circle having isotropy, but in order to ensure smooth passage of irregular gas, the aspect ratio is controlled to be 2: preferably 1 or more, and the cross-sectional shape is designed to be approximately rectangular or approximately elliptical.
In particular, it is recommended to use an approximately rectangular heated aromatic generation substrate having an approximately rectangular cross-sectional shape to form pores and ensure a smooth gas passage. Specifically, the length of the minor axis of the rectangular parallelepiped vertical cross section is preferably controlled to 0.1 to 1.0mm, more preferably 0.1 to 0.5 mm. Regarding the cross section perpendicular to the length direction of the rectangular parallelepiped, the length of the long axis is preferably controlled to be 0.5 to 3.0mm, more preferably 0.5 to 2.0 mm.
In addition, it is recommended that the vertical cross-sectional shape in the longitudinal direction of the heated aroma-generating substrate be uniform in the longitudinal direction because: the heated aroma generating body (formed by winding the heated aroma generating base material by using the packaging member) can be ensured to be uniform in the length direction, and the gas channel can penetrate through the heated aroma generating body.
On the other hand, the ratio of the length of the minor axis of the vertical cross section of the heated fragrance generating substrate (constituting the heated fragrance generator) to the length in the longitudinal direction is determined by the size of the cavity or the like of the heated fragrance generator (using the fragrance cartridge), and the causal relationship between the porosity of the vertical cross section in the longitudinal direction of the heated fragrance generator is weak. However, in order to perform a comfortable pumping using the heated aromatic generator (having irregular gas channels) of the present invention, a proper length should be designed, and the ratio of the length in the length direction to the length in the short axis direction is controlled to be 10: 1-700: preferably 1. In addition, as the heated aromatic generating base material, it is preferable that the specific length of the most recommended approximately rectangular parallelepiped in the longitudinal direction is also controlled to 10 to 70 mm.
In the heated aromatic generating body having the anisotropic vertical cross-sectional shape in the longitudinal direction, the contact rate between one surface in the long axis direction of the vertical cross-section in the longitudinal direction and one surface in the long axis direction of the vertical cross-section in the longitudinal direction of the adjacent heated aromatic generating substrate is increased as compared with one surface in the short axis direction of the vertical cross-section in the longitudinal direction of the adjacent heated aromatic generating substrate, thereby ensuring the smooth gas passage and improving the filling rate.
In addition, in the heated aromatic generating body having the anisotropic vertical sectional shape in the longitudinal direction, as for the number of the heated aromatic generating base materials, the number of the heated aromatic generating base materials distributed in such a manner that the long axis direction of the vertical sectional shape in the longitudinal direction is the same as the circumferential tangential direction of the heated aromatic generating body is larger than the number of the heated aromatic generating base materials distributed in such a manner that the long axis direction is the same as the circumferential normal direction of the heated aromatic generating base materials, thereby ensuring the smooth passage of gas and improving the filling rate.
Therefore, the aromatic cigarette cartridge equipped with the heated aromatic generator is installed in the heating type aromatic device for smoking, and has the following advantages: can make the smoker smoke comfortable smoke gas aerosol and aromatic components; increasing the fill rate of the heated aroma generating substrate; ensuring proper smoking times; the problem of burning of the heated aromatic generation base material during smoking and the problem of falling of the heated aromatic generation base material caused during mounting/dismounting of the aromatic cigarette cartridge are solved; the aromatic cigarette bullet is conveniently inserted into the heating body (arranged in the cavity of the heating aromatic device).
Although such a heated aroma generating substrate has a high filling rate, the following heated aroma generating body manufacturing method plays an important role in the formation of a heated aroma generating body having irregular gas channels to ensure the gas channels to be smooth.
That is, the method for producing a heated aromatic substance according to the present invention comprises the following five steps. A first step: cutting the heated aromatic generating sheet into a noodle-shaped heated aromatic generating base material, and ensuring that the cross section shape formed by vertically cutting along the length direction is kept uniform in the length direction and the length of the cross section is more than 2 times of that of the heated aromatic generating body; a second step: loading a certain amount of noodle-shaped heated aromatic generating base material on a heated aromatic generating body packaging member net with a specified width, supporting and conveying the base material through a conveying belt, and keeping the base material parallel to the length direction of the heated aromatic generating body packaging member net; a third step: bending the conveyor belt to make the noodle-shaped heated aroma generating base material pass through the heated aroma generating body packaging member net and roll the noodle-shaped heated aroma generating base material into a cylinder along the length direction; a fourth step: linearly bonding the web of the heated aromatic generator packaging member of the rod-like heated aromatic generator produced by the third step in the longitudinal direction; a fifth step: the rod-shaped heated aromatic substance produced in the fourth step is cut into a predetermined length.
The third process (i.e., the method of manufacturing the heated aromatic generator) is the most important process for forming the irregular gas channels in the heated aromatic generator. In the process, the noodle-shaped heated aromatic generating base material is aligned along the length direction of the heated aromatic generating body, is loaded to the packaging member net of the heated aromatic generating body and is supported and conveyed by the conveyor belt, and along with the bending operation of the conveyor belt, the noodle-shaped heated aromatic generating base material passes through the packaging member net of the heated aromatic generating body and is rolled into a cylinder along the length direction to form a long rod-shaped heated aromatic generating body, and the internal structure of the heated aromatic generating body is determined. The irregular gas channel with high porosity is formed by pores formed by primary aggregates (formed by moving and aggregating a noodle-shaped heated aromatic generation substrate along with the bending operation of a conveyor belt), further formed by secondary aggregates (formed by moving and aggregating a noodle-shaped heated aromatic generation substrate monomer and a primary aggregate), and formed by the pores and penetrating through the irregular gas channel of the heated aromatic generation body, meanwhile, the noodle-shaped heated aromatic generation substrate monomer, the primary aggregate and a packaging member form pores, and further formed by the irregular gas channel penetrating through the noodle-shaped heated aromatic generation body. On the one hand, the filling rate is improved because: in the later stage of the process, along with the bending operation of the conveyor belt, the packing component wraps the strip-shaped heated aromatic generating base material (from the length direction and the vertical direction of the base material) to form a cylindrical long rod-shaped heated aromatic generating body. The more the heating substrate is close to the cylindrical shape, the more easily the noodle-shaped heating substrate (primary aggregate and secondary aggregate of the noodle-shaped heating substrate) slides and moves, so that the contact rate between one surface of the noodle-shaped heating substrate in the long axis direction of the vertical section and one surface of the adjacent heating substrate in the long axis direction of the vertical section is increased, and meanwhile, the number of the noodle-shaped heating substrate distributed in the circumferential tangential direction in the long axis direction is increased. Further, the filled state of the noodle-like heated aroma generating base material in the peripheral region can form a stable and firm structure. In contrast, the above-mentioned primary aggregates and secondary aggregates having a large volume remain in the central region of the rod-shaped heated aromatic generator, whereby irregular gas passages formed by the primary aggregates and the secondary aggregates remain, and the central region has a higher porosity than the peripheral region. The heated aroma generating body for the aromatic cigarette cartridge is obtained by cutting the rod-shaped heated aroma generating body (with the internal structure formed in the way), and the internal structure of the heated aroma generating body is completely the same as the internal structure.
That is, a noodle-shaped heated aromatic generating base material (the noodle-shaped heated aromatic generating base material has a length longer than the length of the heated aromatic generating body in the longitudinal direction and a cross-sectional shape substantially the same as that of the heated aromatic generating body) is loaded in the longitudinal direction of a roll-shaped heated aromatic generating body packaging member net, and is wrapped in a cylindrical shape along the longitudinal direction, and irregular gas passages of the bar-shaped heated aromatic generating body are used as through holes, and in the wrapping process, as the noodle-shaped heated aromatic generating base material forms a cylindrical shape, primary aggregates and secondary aggregates are generated and form irregular gas passages, respectively, and at the same time, irregular gas passages are also formed between the packaging members. In this process, the primary aggregate and the secondary aggregate remain in the central region of the columnar rod-like heated aroma generating base, but in the peripheral region, the contact rate between the long axis direction of the vertical cross section of the noodle-like heated aroma generating base material and the long axis direction of the vertical cross section of the adjacent noodle-like heated aroma generating base material increases, and the proportion of the distribution in the circumferential tangential direction of the column increases, thereby increasing the filling rate.
The shape of the noodle-shaped heated aromatic generation base material is important for controlling the distribution, and the aspect ratio of the major axis length to the minor axis length of the vertical cross section in the length direction of the noodle-shaped heated aromatic generation base material cut in the first step is controlled to be 1: 1-30: 1, and the aspect ratio of the length in the longitudinal direction to the length in the minor axis is controlled to be 40: 1-3600: preferably 1. In particular, the aspect ratio of the major axis length to the minor axis length is controlled to be 2: 1-20: 1 is better, and the control is carried out in the following steps of 5: 1-20: 1 is most preferred. These aspect ratios are closely related to the mobility of the noodle-like heated aroma generating substrates (which are distributed side by side in the longitudinal direction) when wrapped in a cylindrical shape from the longitudinal direction and the vertical direction, so that the gas passage can be ensured to be unobstructed, and the filling rate can be improved. Therefore, when the aspect ratio of the major axis length to the minor axis length of the vertical cross section in the longitudinal direction exceeds 30: 1, and the aspect ratio of the length in the longitudinal direction to the length of the minor axis exceeds 3600: 1, the frequency of contact with one surface of the noodle-like heated aromatic generator in the major axis direction increases, and the removability is extremely low, and it is difficult to form primary aggregates and secondary aggregates. And when the aspect ratio of the length of the long axis to the length of the short axis is 1: 1, the noodle-shaped heated aromatic generating bodies may be distributed in the most compact filling structure according to different manufacturing conditions.
The cross-sectional shape perpendicular to the longitudinal direction of the noodle-like heated aroma-generating substrate may be designed to be a regular polygon (e.g., equilateral triangle, square, and regular pentagon) or a circle having an isotropy, but in order to form the gas passage, it is more preferable to design the cross-sectional shape to be a rectangle (having a short axis and a long axis) or an ellipse, and it is most preferable to design the cross-sectional shape to be a nearly rectangle.
In addition, the third step (wrapping the noodle-shaped heated aroma-generating substrate of the present invention in a cylindrical shape along the length direction) has the following features: the noodle-shaped heated aroma-generating substrate (loaded onto the packaging member and the packaging member supported and conveyed by the conveyor belt as the conveyor belt moves) is passed through a guide (provided with a groove that can gradually bend the conveyor belt into a cylindrical shape). For example, such a conveyor belt may be a conveyor belt used in paper cigarettes.
As is clear from the above description, when the vertical cross-sections of the central region and the peripheral region in the length direction of the heated aroma generator are equally divided, the central region has a higher porosity than the peripheral region, and this state is directly reflected on the heated aroma generator (incorporated in the aromatic cartridge).
This is closely related to the fact that in winding a noodle-like heated aroma generating substrate (the shape of the vertical cross section in the longitudinal direction has anisotropy) with a packaging member and forming a primary aggregate and a secondary aggregate, the contact rate between one surface in the long axis direction of the vertical cross section in the longitudinal direction and one surface in the long axis direction of the vertical cross section in the longitudinal direction of the adjacent heated aroma generating substrate increases (as compared with one surface in the short axis direction of the vertical cross section in the longitudinal direction of the adjacent heated aroma generating substrate). Moreover, it is also closely related to the following factors: in this process, the number of the noodle-shaped heated aroma generating substrates (the major axis direction of the perpendicular cross section of the noodle-shaped heated aroma generating substrate in the length direction is distributed in the circumferential tangential direction of the noodle-shaped heated aroma generating body) is greater than the number of the noodle-shaped heated aroma generating substrates distributed in the circumferential normal direction of the noodle-shaped heated aroma generating body in the major axis direction.
As described above, although the shape of the noodle-like heat-generated fragrance generating base material has a great influence on the vertical cross-sectional structure in the longitudinal direction of the rod-like heat-generated fragrance generating body, the structure formation may be controlled by changing the conveying speed of the conveyor, the shape of the guide, and the like.
In addition, in order to simplify and promote the linear adhesion of the heated fragrance generator packaging member in the longitudinal direction, it is recommended to adopt the following means: another process is added (in parallel with the first process, a prescribed position of the web of the heated aroma generating body packaging member is coated with a prescribed amount of hot melt adhesive), and a heating manner is designed in the fourth process.
The above-mentioned method for producing a heated aromatic substance can be carried out continuously by the following apparatus. That is, the apparatus for producing a heated aromatic substance of the present invention can continuously drive: a supply device that cuts the heated aroma generating sheet into a noodle-like heated aroma generating base material, a drive device of an endless conveyor belt (for supporting and conveying a heated aroma generating body wrapping member web), a guide (provided on a conveying path of the endless conveyor belt, having a plurality of grooves), a bonding device (for bonding the heated aroma generating body wrapping member web), and a cutter (for cutting a rod-like heated aroma generating body (made by winding the noodle-like heated aroma generating body base material using the heated aroma generating body wrapping member web)). Here, regarding the groove having a plurality of guides, it is recommended to design 3 to 4 different guides so as to gradually form a cylindrical shape from a crescent-shaped groove to a nearly full moon-shaped groove through a crescent-shaped groove.
In addition, it is more preferable that the apparatus for manufacturing a heated aromatic generator of the present invention is designed to have the following features: in order to simplify the bonding process of the heated aroma generator packaging member, a supply device (providing a noodle-like heated aroma generating base material obtained by cutting the heated aroma generating sheet), a supply device (providing a heated aroma generator packaging member web (coating a specified position of the heated aroma generator packaging member web with a fixed amount of hot melt adhesive)), a drive device (an endless conveyor belt for supporting and conveying the heated aroma generator packaging member web), a guide (provided on a conveying path of the endless conveyor belt and having a plurality of grooves), a heating device for the heated aroma generator packaging member web, and a cutting machine (for cutting a rod-like heated aroma generator (made by winding a noodle-like heated aroma generator base material using the heated aroma generator packaging member web)) are continuously driven.
The heated aroma generator described above is used as the heated aroma generator (20 and 110) shown in FIGS. 1, 2, 4 to 7 and 10 to 17. In particular, fig. 10 to 14 show various examples of aromatic cartridges obtained by connecting a heated aroma generating body (20), a cooling member (40), a filter member (50), and a mouthpiece (60) in this order, and fig. 15 and 16 show examples of aromatic cartridges using the filter member (50) instead of the mouthpiece.
The cooling region determining member (40) shown in fig. 10 is abutted with the heated aroma generating body (20) at the upstream side U, and is, for example, wound into a cylindrical cardboard having an outer diameter of 5.5mm and a length of 25 mm.
The filter member (50) shown in fig. 10 is abutted with the cooling region determining member (40) at the upstream side U. The filter member (50) is a cylindrical cellulose acetate fiber wound, for example, in a cylindrical shape having an outer diameter of 5.5mm and a length of 8 mm.
The mouthpiece (60) shown in fig. 10 is adjacent to the filter member (50) at the upstream side U. The cigarette holder (60) is a cylindrical cardboard wound to an outer diameter of 5.5mm and a length of 8 mm.
The outer diameters of the heated aroma generating body (20), the cooling region determining member (40), the filter member (50) and the mouthpiece (60) are preferably controlled to be 4.7 to 6.1 mm. It is recommended to apply the heated aroma generating body having such an outer diameter to a smoking device main body heated from the periphery of the heated aroma generating body. The reason is that: the heat energy obtained from the surroundings can be efficiently transferred to the whole heated aromatic generator. The cross section of the smoking article is usually circular, so it is indicated by "outer diameter", but when assuming a rectangular cross section, it is recommended to indicate by "perimeter", where the perimeter is 14.8 to 19.2 mm.
The heated aroma generating body (20), the cooling region determining member (40), the filter member (50), and the mouthpiece (60) are packaged using a packaging member (70).
The various dimensions shown in fig. 9-1 and 10 are merely exemplary and other dimensions may be designed.
Fig. 11 is a schematic cross-sectional view of the mode of use of the aromatic cigarette cartridge (80).
The aromatic cigarette bullet (80) is mounted on the smoking device main body (90) for use. The smoking device main body (90) heats the heat-receiving aroma generating body (20) of the aromatic cigarette bullet (80) from the surrounding part thereof by electric power supplied from a battery (not shown) provided in the smoking device main body (90). The heated aroma generating body (20) generates an aerosol containing aroma components upon heating, and the generated aerosol moves from the upstream U side to the downstream D side and is partially inhaled by the user through the mouthpiece (60).
The aerosol is cooled while passing through the inside of a cooling region determining member (40) (a paperboard wound in a cylindrical shape). I.e. the inside of the cooling region defining member (40) is a cooling region for cooling the aerosol. The cooling area depends on the cooling area determining member (40). The function of the filter member (50) is: particles contained in the gas inhaled by, for example, a user are removed.
Fig. 12 to 16 are schematic perspective views of modified aromatic cartridges.
An embodiment of a cigarette cartridge will be described with reference to modification 1. Fig. 12 is a schematic perspective view of a cigarette cartridge according to modification 1.
The aromatic cigarette cartridge of modification 1 has the following features: according to the aromatic cartridge (80) of the embodiment, a plurality of holes (ventilation areas) (50a) are formed at equal intervals in the circumferential direction of the filter member (50) at corresponding positions of the packing member (70) and the filter member (50). The hole (50a) penetrates the packing member (70), and a recess is formed in the filter member (50). The holes (50a) are perforated at a distance of 2mm from one end side of the filter member (50). The number of the holes (50a) may be designed to be 12 to 36 (for example, 24).
The holes (50a) are formed in the filter member (50), so that a user can more easily inhale the aerosol containing the aromatic component, and when the user inhales the aerosol through the mouthpiece (60), the aerosol, which stays in the cooling region depending on the cooling region determining member (40) and has the natural aroma of the aromatic base material, is cooled together with the external air, which flows in through the holes (50a), it is possible to better disperse finer aerosol particles in the air inhaled by the user, and the aerosol thus generated is more advantageous for the smoker to enjoy the aroma. In addition, the user can be encouraged to inhale the aerosol containing the aromatic component more easily while avoiding the user from inhaling the aerosol at a high temperature, and therefore, the aromatic cartridge of this modification can make the smoker enjoy the natural aroma of the aromatic substrate better.
An embodiment of the aromatic cigarette bullet will be described with reference to modification 2. Fig. 8 is a schematic perspective view of a cigarette cartridge according to modification 2.
In modification 1, a plurality of holes 50a are formed at equal intervals in the circumferential direction of the filter member 50 at corresponding positions of the packing member 70 and the filter member 50. In contrast, in the 2 nd modification, a plurality of holes (ventilation regions) (50b) are formed at equal intervals in the circumferential direction of the cooling region determining member (40) at corresponding positions of the packing member (70) and the cooling region determining member (40). The hole (50b) means a through hole penetrating the paperboard constituting the packing member (70) and the cooling region determining member (40). The hole (50b) is formed by punching at a distance of 2mm from the other end side of the cooling region determining member (40). The number of the holes (50b) may be designed to be 12 to 36 (for example, 24).
Holes (50b) are formed in the filter member (50), and therefore, when a user inhales through the mouthpiece, the aerosol, which stays in the cooling region depending on the cooling region determining member (40) and contains the natural fragrance of the fragrant base material, is greatly stirred/cooled together with the outside air, which flows in through the holes (50 b). As a result, finer aerosol particles can be better dispersed in the air inhaled by the user, and the resulting aerosol is more favorable for the smoker to enjoy the aroma. In addition, the user can be encouraged to inhale the aerosol containing the aromatic component more easily while avoiding the user from inhaling the aerosol at a high temperature, and therefore, the aromatic cartridge of this modification can make the smoker enjoy the natural aroma of the aromatic substrate better.
In another embodiment of modification 2, the aromatic cigarette cartridge of modification 2 does not include a mouthpiece (60) made of cardboard (wound in a cylindrical shape). For example, as shown in fig. 15, a mouthpiece region (50m) where a user performs suction with the mouth depends on a downstream D-side region of the filter member (50). The length of the filter member (50) (made of cellulose acetate fibers (formed in a cylindrical shape)) is 8mm in the modification 2, and is 16mm in the other embodiment of the modification 2.
In another embodiment of modification 2, the aromatic cigarette cartridge of modification 2 does not include a mouthpiece (60) made of cardboard (wound in a cylindrical shape). For example, as shown in fig. 15, a mouthpiece region (50m) where a user performs suction with the mouth depends on a downstream D-side region of the filter member (50). In the 2 nd modification, the cooling region determining member (40) is set to 25 mm. In another embodiment of the 2 nd modification, the cooling region defining member (40) is set to 30 to 35mm (for example, 31mm), and the length of the filter member (50) is set to 10mm or the like. The cooling region determining member (40) can maintain fragrance and taste for a long time, and thus has the following advantages: the cooling region determining member (40) can stably obtain the natural fragrance and taste of the fragrant base material even if a large amount of inhalation is made.
An embodiment of the aromatic cigarette bullet will be described with reference to modification 3. Fig. 14 is a schematic perspective view of a cigarette cartridge according to modification 3.
The aromatic cigarette cartridge of modification 3 has the following features: in the aromatic cartridge (80) of the embodiment, a plurality of holes (50a) are formed at equal intervals in the circumferential direction of the filter member (50) at corresponding positions of the wrapper member (70) and the filter member (50), and a plurality of holes (50b) are formed at equal intervals in the circumferential direction of the cooling region determining member (40) at corresponding positions of the wrapper member (70) and the cooling region determining member (40). The holes (50a) are perforated at a distance of 2mm from one end side of the filter member (50). The hole (50b) is formed by punching at a distance of 2mm from the other end side of the cooling region determining member (40).
Therefore, when a user draws through the mouthpiece, the aerosol, which stays in the cooling region (depending on the cooling region determining member (40)) and contains the natural aroma of the aromatic base material, is greatly stirred/cooled together with the outside air flowing in through the holes (50b), and is cooled together with the outside air flowing in through the holes (50a), with the result that finer aerosol particles can be better dispersed in the air inhaled by the user, and the aerosol thus produced is more suitable for the smoker to enjoy the aroma. In addition, since the user can be encouraged to inhale the aerosol containing the aromatic component more easily while avoiding the inhalation of the aerosol of high temperature, the aromatic cartridge of this modification can make the smoker enjoy the natural aroma of the aromatic base material better than the variants 1 and 2.
An embodiment of the aromatic cigarette bullet will be described with reference to modification 4. Fig. 15 is a schematic perspective view of a cigarette cartridge according to modification 4.
The aromatic cigarette cartridge according to modification 4 does not include a mouthpiece (60) made of cardboard (wound in a cylindrical shape). The mouthpiece region (50m) for the user's mouth suction depends on the downstream D-side region of the filter member (50). For example, in the 4 th modification, the length of the filter member (50) (made of cellulose acetate fibers (formed in a cylindrical shape)) may be set to 16 mm.
The aromatic cartridge according to modification 4 includes a heated aroma generating body (20), a cooling region determining member (40), and a filter member (50) which are adjacently disposed in this order. The aromatic cigarette cartridge has a cylindrical shape, an outer diameter of 5.5mm and a length of 83 mm.
If the mouthpiece (60) made of cardboard (wound in a cylindrical shape) is not designed and the filter member (50) is used instead of the mouthpiece (60), the number of parts and the number of assembly man-hours for manufacturing the aromatic cartridge can be reduced.
As another embodiment of the 4 th modification, the cooling region determining member (40) may be set to 31mm, and the length of the filter member (50) may be set to, for example, 10 mm. The cooling region determining member (40) can maintain fragrance and taste for a long time, and thus has the following advantages: the cooling region determining member (40) can stably obtain the natural fragrance and taste of the fragrant base material even if a large amount of inhalation is made.
Another embodiment of the 4 th modification includes an embodiment in which the size of the cooling region defining member (40) is set to be smaller than 10 to 15 mm. For example, in one embodiment, the cooling region determining member (40) is set to 14mm, and the length of the filter member (50) is set to 27 mm. The shortened cooling zone determining means (40) has the advantage that the natural aroma and taste of the aroma substrate is fully tasted after the first smoking action.
An embodiment of a cigarette cartridge will be described with reference to modification 5. Fig. 16 is a schematic perspective view of a cigarette cartridge according to modification 5.
The difference between the 5 th modification and the 4 th modification is that: in the aromatic cartridge of modification 4, a plurality of holes (50a) are formed at equal intervals in the circumferential direction of the filter member (50) at corresponding positions of the packing member (70) and the filter member (50). The hole (50a) is formed beside the side end of the cooling region determining member (40). The hole (50a) penetrates the packing member (70), and a recess is formed in the filter member (50). The holes (50a) are perforated at a distance of 2mm from one end side of the filter member (50). The number of the holes (50a) may be designed to be 12 to 36 (for example, 24).
The holes (50a) are formed in the filter member (50), so that a user can more easily inhale the aerosol containing the aromatic component, and when the user inhales the aerosol through the mouthpiece, the aerosol, which stays in the cooling region depending on the cooling region determining member (40) and contains the natural aroma of the aromatic base material, is cooled together with the external air, which flows in through the holes (50a), it is possible to better disperse finer aerosol particles in the air inhaled by the user, and the aerosol thus generated is more favorable for the smoker to enjoy the aroma. In addition, the user can be encouraged to inhale the aerosol containing the aromatic component more easily while avoiding the user from inhaling the aerosol at a high temperature, and therefore, the aromatic cartridge of this modification can make the smoker enjoy the natural aroma of the aromatic substrate better.
If the mouthpiece (60) made of cardboard (wound in a cylindrical shape) is not designed and the filter member (50) is used instead of the mouthpiece (60), the number of parts and the number of assembly man-hours for manufacturing the aromatic cartridge can be reduced.
As another embodiment of the 5 th modification, the cooling region determining member (40) may be set to 31mm, and the length of the filter member (50) may be set to 10 mm. The cooling region determining member (40) can maintain fragrance and taste for a long time, and thus has the following advantages: the cooling region determining member (40) can stably obtain the natural fragrance and taste of the fragrant base material even if a large amount of inhalation is made.
In addition, as another embodiment of the 5 th modification example, an embodiment in which the size of the cooling region defining member (40) is designed to be smaller than 10 to 15mm, and the like can be cited. For example, in one embodiment, the cooling region determining member (40) is set to 14mm, and the length of the filter member (50) is set to 27 mm. The shortened cooling zone determining means (40) has the advantage that the natural aroma and taste of the aroma substrate is fully tasted after the first smoking action.
As shown in fig. 15 and 16, in the aromatic cigarette cartridges according to the 4 th and 5 th modifications, the length of the cooling region defining member (40) is set to 25mm, and the length of the filter member (50) is set to 16mm, but the lengths of the cooling region defining member (40) and the filter member (50) may be appropriately changed. For example, under the condition that the sum of the length of the cooling region determining member (40) and the length of the filtering member (50) is 41mm, the length of the cooling region determining member (40) may be set to 10 to 35mm, and the length of the filtering member (50) may be set to 6 to 31mm, etc. The length of the cooling region specifying member (40) may be 10mm or more. When the length of the cooling region determining member (40) is 10mm or more, the cooling effect can be sufficiently ensured.
The different length designs of the cooling zone defining member (40) have the following different effects: when the length of the cooling area determining member (40) is more than 10mm and less than 15mm, the natural aroma and taste of the aromatic substrate can be fully absorbed after the first smoking action; when the length of the cooling region defining member (40) is 15-30 mm, the natural aroma and taste of the aromatic base material can be stably inhaled by the smoking action after smoking starts. However, when the length of the cooling region determining member (40) exceeds 30mm, it is preferable to control the length to 45mm or less, and it is more preferable to control the length to 35mm or less. When the length of the cooling region defining member (40) is 45mm or less, a preferable cooling state can be obtained. When the length of the cooling region defining member (40) is 35mm or less, a more preferable cooling state can be obtained.
With respect to the position of the perforation (50a) in the filter member (50), provided in a region within 4mm from one end side of the filter member (50), aerosol particles are cooled together with outside air (flowing in through the perforation (50 a)), so that finer aerosol particles can be easily dispersed in air inhaled by a user. When the dispersion is provided in a region within 2.5mm from one end side of the filter member (50), a more preferable dispersion state can be obtained.
With regard to the position of the perforation (50a) in the cooling region determining member (40), being provided in a region within 4mm from one end side of the cooling region determining member (40), finer aerosol particles can be easily dispersed in the air inhaled by the user, among others, because: the aerosol particles are cooled together with the outside air (flowing in through the holes (50 b)), and when disposed in a region within 2.5mm, the dispersed state can be obtained more efficiently.
As described above, the present invention has been explained using the examples and the modified examples, but the present invention is not limited thereto. For example, the heated aroma-generating substrate (10) in the form of a strip having a length of 42mm, a width of 1.5mm and a thickness of 0.3mm was used in the examples and the modification examples. For example, a strip-shaped heated aromatic generating substrate with a length of 20 to 54mm, a width of 0.5 to 3.0mm and a thickness of 0.1 to 0.5mm can also be used. If the substrate is a rod, a heated aromatic base material having a length of 20 to 54mm and an outer diameter of 0.2 to 3.0mm can be used. As another example, the length of the filler in the form of a stick or a bar may be 34mm or more, preferably 50mm or less, and more preferably 34 to 50 mm. When the filler in the form of a stick or a stick is heated by the smoking device body, aerosol (containing an aromatic component of the aromatic base material) is easily generated from the filler, and such a design is recommended.
Moreover, the aromatic cartridge has the following features: the heated aroma generating substrate comprises an aroma substrate (aroma generating source) and an aerosol, wherein the content of the aroma substrate (aroma generating source) is 30 to 90 mass%, and the content of the aerosol is 5 to 40 mass%, and the heated aroma generating body (provided with the heated aroma generating substrate) contains at least 0.12g of the aroma substrate (aroma generating source) and at least 0.02g of the aerosol.
In the present specification, the "rod-shaped heated aroma-generating substrate" refers to a heated aroma-generating substrate having a shape in the longitudinal direction and a cross section in the direction orthogonal to the longitudinal direction being a perfect circle or an ellipse. In the "rod-shaped heated aroma-generating substrate", the "outer diameter" represents the diameter when the cross section is a perfect circle, and the length of the major axis when the cross section is an ellipse. In the present specification, even when the cross section in the direction orthogonal to the longitudinal direction is a polygon, the cross section is referred to as a "rod-shaped heated aroma-generating substrate", and the diameter of a circumscribed circle having the largest diameter among one or more circles circumscribed with the polygon is defined as an "outer diameter".
In the examples and modifications, the heated aroma generating body (20) is used (formed by winding the heated aroma generating substrate (10) around the packaging member (30)), but the packaging member (70) may be used as the packaging member (30) around which the heated aroma generating substrate (10) is wound. Since the air flow of the aerosol is stable, it is easier for the user to inhale the fragrant components.
In the aromatic cigarette cartridges of the embodiments and the modifications, a cover may be provided on the upstream U side of the heat-receiving aromatic generator (20). This design has the following effects: suppressing the dissipation of the fragrance in the heated fragrance-generating substrate (10); the heated aroma generating substrate (10) is prevented from falling off the cigarette cartridge, for example, during transport of the cigarette cartridge. The effect of the cap can be achieved using filters, paper, sponge, etc. In addition, a cover may be provided on the downstream D side of the heated aroma generating body (20).
The 1 st and 2 nd adhesives may also be used as an aromatic base material (aromatic generation source).
In the embodiment, the heated aroma generating body (20), the cooling region determining member (40), the filter member (50), and the mouthpiece (60) are sequentially disposed adjacent to each other, and are wound with a wrapping member (70) (e.g., cigarette paper) to form an aromatic cartridge. The heated aroma generating body (20), the cooling region determining member (40), the filter member (50), and the mouthpiece (60) may be inserted in this order into a cylindrical wrapping member (70) formed in advance to produce an aromatic cartridge. After a part of the members is wound using a packing member (70), the remaining members are inserted to be manufactured. For example, the aromatic cartridge according to modification 4 (see fig. 15) can be manufactured by winding a heated aromatic generator (20) 42mm long and a cooling region determining member (40) 25mm long around a wrapping member (70) 83mm long and then inserting a filter member (50) 16mm long.
In the production of the aromatic cartridge of the embodiment, the heated aromatic generator (20) (length 42mm), the cooling region determining member (40) (length 25mm), the filter member (50) (length 8mm), and the mouthpiece (60) (length 8mm) were wound with the wrapping member (70) having a length of 83mm (the sum of the lengths of the members described below), but the wrapping member (70) having a length shorter than the sum of the lengths of the members may be wound. For example, as shown in fig. 17, a wrapping member (70) having a length (a length that can cover the entire of the mouthpiece (60) (length 8mm), the filter member (50) (length 8mm), the cooling region determining member (40) (length 25mm), and the heated aroma generating body (20) portion) described below was used for winding to manufacture an aromatic cartridge.
In the aromatic cartridges of the examples and the modification in which the plurality of strip-shaped heated aroma-generating substrates are aligned in the longitudinal direction, the number of failures is reduced. The fault comprises the following steps: when the aromatic cigarette cartridge is mounted on the smoking device main body, the heated aroma generating base material (10) (included in the heated aroma generating base material (20)) is broken to cause a failure. In order to prevent the heated aroma generating base material (10) from being broken, when the heated aroma generating base material (10) is in a strip shape, more than 9 heated aroma generating base materials (10) are recommended to be wrapped in the heated aroma generating body (20); when the heated aroma generating substrate (10) is rod-shaped, it is recommended that 15 or more heated aroma generating substrates (10) be wrapped in the heated aroma generating body (20).
When the length of the filler in the form of a stick or a stick is substantially equal to the length of the heated aroma generating body (20), breakage does not easily occur.
It is common knowledge of those skilled in the art that various alterations, improvements, combinations, and the like can be made.
Hereinafter, the present invention will be described in more detail by way of production examples and examples. However, the technical scope of the present invention is not limited to the following examples. In the examples described below, the operations were carried out at room temperature (25 ℃) unless otherwise stated. In addition, "%" and "part(s)" represent "% by mass" and "part(s) by mass", respectively, unless otherwise specified.

The thickness of the aromatic base composition sheet thus produced was 0.3 mm. The sheet of the aromatic base material composition was cut into a rectangular shape having a length of 150mm and a width of 240 mm. The cut product was then processed into a rectangular shape having a width of 15mm, a length of 50mm and a thickness of 0.3 mm. The mass of the sheet of the aromatic base material composition after processing was about 0.30 g. This sample was used for the following evaluation 1.

The aromatic base material composition sheet was cut into a rectangular shape having a length of 150mm and a width of 240 mm. The cut product was fed to a rotary cutter and processed into a sheet cut product having a width of 1.5mm, a length of 240mm and a thickness of 0.1 mm. 150 cut pieces of the above sheet material were bundled and aligned in the longitudinal direction, and then wrapped with paper having a basis weight of 34g/m2, glued, and formed into a cylindrical shape (roll). The inner diameter of the cylinder was set to 6.9 mm. This cylinder (roll) was cut into a length of 12.0mm to obtain a heated aroma generator. That is, a heated aroma-generating body (including a heated aroma-generating substrate) having a width of 1.5mm, a length of 12.0mm and a thickness of 0.1mm was obtained. The mass of the heated aromatic generator was 0.29g, and the volume filling ratio of the filler to the volume of the heated aromatic generator was 0.60.
(production example 3)
In the same manner as in production example 1, a fragrance base material composition was prepared. The following filler forming process [ mode ] (F) was used to prepare a sheet of the aromatic base material composition having a thickness of 0.3 mm. The sheet of the aromatic base material composition was cut into a rectangular shape having a length of 150mm and a width of 240 mm. The cut product was fed to a rotary cutter and processed into a sheet cut product having a width of 1.5mm, a length of 240mm and a thickness of 0.3 mm. After 50 of the above-mentioned cut sheets were bundled and aligned in the longitudinal direction, they were wrapped with paper having a basis weight of 34g/m2, glued and formed into a cylindrical shape (roll). The inner diameter of the cylinder was set to 6.9 mm. This cylinder (roll) was cut into a length of 12.0mm to obtain a heated aroma generator. That is, a heated aroma-generating body (including a heated aroma-generating substrate) having a width of 1.5mm, a length of 12.0mm and a thickness of 0.3mm was obtained. The mass of the heated aromatic generator was 0.29g, and the volume filling ratio of the filler to the volume of the heated aromatic generator was 0.60.
Production example 4

Production example 35
100 parts by mass of xylitol
400 parts by mass of water
The above materials were mixed by stirring to make a xylitol/water solution.
Next, a black tea leaf material prepared by the following processing was used: black tea leaves were dried at 70 ℃, pulverized, and sieved through an 80-mesh sieve. The water content of the obtained dried and pulverized product was 2 mass%. Likewise, a gynostemma pentaphylla material was used which was prepared by the following process: pulverizing dried Gynostemma pentaphyllum Makino, and sieving with 80 mesh sieve.
Figure GDA0002877383700000902
Figure GDA0002877383700000911
The above materials were put into a mixer and mixed for 15 minutes to obtain a 1 st mixture.
The obtained 1 st mixture was used in the 2 nd mixing step [ mode ]. 100 parts by mass of the aforementioned 1 st mixture was mixed using a three-roll mill, and 0.5 part by mass of glucomannan and 20 parts by mass of water were added. Then, a doctor blade was pressed against the roll to collect the sheet, and this process [ mode ] was repeated 8 times to obtain a 2 nd mixture (aromatic base material composition). This step [ mode ] is used as part of both the 2 nd mixing step [ mode ] and the filler forming step [ mode ] (F).
The 2 nd mixture (aromatic base material composition) was kneaded/dispersed using a three-roll mill to prepare a sheet having a desired thickness. The thickness of the aromatic base composition sheet thus produced was 0.3 mm. The sheet of the aromatic base material composition was cut into a rectangular shape having a length of 150mm and a width of 240 mm. The cut product was fed to a rotary cutter and processed into a sheet cut product having a width of 1.5mm, a length of 240mm and a thickness of 0.3 mm. After 50 of the above-mentioned sheet cuts were bundled and aligned in the longitudinal direction, they were wrapped with paper having a basis weight of 34g/m2, and glued to make a cylindrical shape (roll). The inner diameter of the cylinder was set to 6.9 mm. This cylinder (roll) was cut into a length of 12.0mm to obtain a heated aroma generator. Thus, a heated aroma-generating body comprising a heated aroma-generating substrate having a length of 12.0mm, a width of 1.5mm and a thickness of 0.3mm was obtained. The heated aromatic substance had a mass of 0.29g and a volume filling ratio of the heated aromatic substance matrix to the volume of the heated aromatic substance matrix was 0.60. The heated aroma generating substrate contains 0.9 parts by mass of polysaccharide (glucomannan), 19 parts by mass of cellulose, and 60 parts by mass of aerosol-forming agent, relative to 100 parts by mass of the aroma substrate. The sheet of the aromatic base material composition is pushed out so that the longitudinal direction is parallel to the rotation axis of the roller and the sheet is pushed out in the rotation direction of the roller in the transverse direction.
The sodium carboxymethylcellulose used in this production example had a solution viscosity of 650 mPas (Brookfield viscometer, 1 mass% aqueous solution, 25 ℃ C.) and the glucomannan (as a polysaccharide) had an aqueous solution viscosity of 44,000 mPas (Brookfield viscometer, 1 mass% aqueous solution, 25 ℃ C.).
Production example 36
Prior to the 1 st mixing step [ mode ], a 1 st mixture was prepared in the same manner as in production example 35. The mixture of the above 1 st stage was sealed in a polyethylene bag and cured at 20 ℃ for 6 days (144 hours) (curing step [ mode ]). After the curing step [ mode ], the apparent volume of the 1 st mixture was about 1.5 times. When the solidified mixture after the solidification step [ mode ] was visually observed, it was found that the ground tea leaves were less free than before solidification. Then, the obtained cured mixture was used in the 2 nd mixing step [ mode ], to obtain a 2 nd mixture. Further, the 2 nd mixing step [ mode ] was performed in the same manner as in production example 35. A heated aromatic substance (including a heated aromatic substance) was produced from the above mixture No. 2 in the same manner as in production example 35. Thus, a heated aroma-generating body comprising a heated aroma-generating substrate having a length of 12.0mm, a width of 1.5mm and a thickness of 0.3mm was obtained. The heated aromatic substance had a mass of 0.29g and a volume filling ratio of the heated aromatic substance matrix to the volume of the heated aromatic substance matrix was 0.60.

Of (3) a through-hole. A filter (140 in fig. 2) having a length of 23mm serving as a mouthpiece was used. As a wrapping member (150 in FIG. 2), paper having a basis weight of 38g/m2 was used, and the wrapping was wound for 2 and a half cycles so that the inner diameter was 6.9m, and then the wrapping was used after being glued. In this manner, when paper having a basis weight of 32g/m2 or more and 45g/m2 or less is wound for 2 and a half cycles to form a paper cylinder and used as the packaging member, it is suitable as an aromatic cartridge for a smoking device main body (used after insertion of a heating element). An adhesive is applied to the inside of a paper cartridge serving as a wrapping member (150 in fig. 2), inserted from the other end side D as a mouthpiece filter (140 in fig. 2), inserted from one end side U as a support member (300 in fig. 2), and then inserted with a heated aroma generating body (110 in fig. 2). Next, paper having a basis weight of 40g/m2 was wound around the mouthpiece portion so as to almost overlap the mouthpiece (140 in fig. 2). In this way, a fragrant cartridge is made.

A fragrant cigarette bomb was produced in the same manner as in example 12, except that the heated fragrance generator produced in production example 46 was used. However, the aromatic base material composition produced in production example 46 was poor in moldability as described above, and the heated aromatic base material was too soft, and it was difficult to produce an aromatic cigarette pack.
[ evaluation ]
The sheet and the aromatic cartridge of the aromatic base material composition prepared as above were evaluated as follows.
(evaluation 9)
The aromatic base material composition sheets prepared in production examples 35 to 37 (and production examples 41 to 43) were subjected to a strength test. The details of the test will be described with reference to fig. 18. A sheet of the aromatic base material composition prepared in each of the above production examples, a set of jigs (600) having a width X of 10.0cm in fig. 18, and a tensile test were performed with a distance Y between the jigs (600) of 20.0 cm. The sheets of each of the fragrance base material compositions used in the tests were 0.3mm thick, 10.0cm across and 22.0cm lengthwise. And (3) test environment: the temperature was 20 ℃ and the humidity was 50% RH. One clamp is held by a holding member (630) and the other clamp is pulled in the direction of arrow (640) by a push-pull force gauge (610) to evaluate the force when the sheet (620) of aromatic substrate composition breaks. Here, the force generated when a sheet of the aromatic base material composition is cracked and the sheet is broken at the time of starting breaking is referred to. Since the toughness of the heated aromatic base material is increased as the force generated at the time of breaking the sheet is increased, it is recommended to use a sheet having a large force generated at the time of breaking. When the above test is performed, if the toughness of the base material is insufficient due to the heated aroma, the filler is highly likely to fall off after smoking, and the force generated when the sheet of the aromatic base material composition is broken is referred to as "sheet strength". The sheet strength is preferably controlled to 3.9N or more, more preferably to 5.0N or more. The sheets of the fragrance base material compositions prepared in production examples 6 and 12 were very soft, and the strength of the sheets could not be evaluated by the above-described method.
