It is preferably 45% by mass or more based on the total amount.

When the residue on the sieve having a mesh size of 250 μm is 8% by mass or less, the microcrystalline cellulose is more likely to exert the effect of suppressing the shrinkage of the aroma-generating substrate to be heated. When the residue on the sieve having a mesh size of 75 μm is 45% by mass or more, the effect of improving the moldability of the aroma generating substrate to be heated is more likely to be exhibited.

The mass average molecular weight (Mw) of microcrystalline cellulose is preferably 10,000 or more and 200,000 or less.

Further, the extract of the aromatic base material exemplified above, the so-called extract, can also be used. Examples of the form of the extract include liquid, starch syrup, powder, granules, and solution.

The above aromatic base material can be used alone or in combination of two or more. Further, among the aromatic base materials of Shiki, those that do not require drying and crushing can be directly used in the mixing step [Means] (M).

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

The aromatic base material as a raw material is subjected to a drying / crushing step [means] (A) and a preparatory step [means] (B), or is directly subjected to a mixing step [means] (M).

In the mixing step [Means] (M), an aromatic base material, an aerosol former, and, if necessary, the above-mentioned microcrystalline cellulose, menthol, polyvinylpolypyrrolidone (water-insoluble crosslinked polymer), water, and the like are added and mixed. , Aroma generating substrate to be heated can be obtained.

When the substrate to generate aroma to be heated contains polysaccharides and celluloses, first, in the step [means] (B1) shown in FIG. 8, celluloses (first binder) to be used as needed are prepared. Then, after mixing in the first mixing step [means] (M1) to obtain the first mixture, the polysaccharide (second binder) is prepared in the step [means] (B2). It is preferable to add the polysaccharide as a second binder in the second mixing step (M2). Further, it is possible to add a curing step [means] (Y) in which the first mixture is held (cured) at a predetermined temperature for a predetermined time after the first mixture is obtained and before the polysaccharide is added. More preferred.

When the solution viscosity of celluloses (first binder) is 300 mPa · s or more, it is easy to mix with the aromatic base material, which is preferable. Further, celluloses (first binder) are preferable when the solution viscosity is 5,000 mPa · s or more because they are suitable for binding (bonding) aromatic base materials. On the other hand, when the solution viscosity of celluloses (first binder) is 50,000 mPa · s or less, the binding (bonding) of the aromatic base material when used together with the polysaccharide (second binder) It is preferable because it is easy to adjust the degree of strength.

In the present specification, the "solution viscosity" is measured using a Brookfield type viscometer, a 1% by mass aqueous solution of the component is prepared, and the temperature is 10 to 30 rpm (0.17 to 0.17 to 0) in an environment of 25 ° C. It is a measured value at the point where the rotation of the rotor is started and the displayed value becomes stable at 0.5s-1).

In the second mixing step [means] (M2), a normal mixer can be used. For example, a mixer in which the materials in the mixing tank are mixed while applying a shearing force with a stirring blade is preferably used. It is also possible to knead using a roll mill, a kneader, an extruder or the like to further strengthen the mixing. In this case, the mixing temperature is preferably controlled to be maintained at 40 ° C. or lower, more preferably 30 ° C. or lower, and even more preferably about 25 ° C. This is because if excessive heat is applied during mixing, the flavor may be dissipated. It is also preferable to pass cooling water through the mixing tank to adjust the temperature.

When the heated aroma generating base material produced through the curing step [means] (Y) is attached to the smoking tool body and smoked, the flavor of the aroma base material is improved. In particular, when tea is used as the aromatic base material, the effect is remarkable, which is preferable. Therefore, according to a preferred embodiment of the present invention, a first mixing step [means] of mixing an aromatic substrate, an aerosol former, and celluloses (first binder) to obtain a first mixture. (M1), the first mixture which has undergone the curing step [means] (Y) and the curing step [means] (Y) in which the first mixture is held at a predetermined temperature for a predetermined time under sealing. Provided is a method [apparatus] for producing a base material for generating aroma to be heated, which has a second mixing step [means] (M2) of adding and mixing a polysaccharide as a binder of 2.

The temperature of the curing step [means] (Y) is preferably 15 ° C. or higher and 30 ° C. or lower. This is because when the temperature is 15 ° C. or higher, the effect of improving the flavor is enhanced, and when the temperature is 30 ° C. or lower, the change in flavor is suppressed and the improvement in flavor is maintained. More preferably, it is 18 ° C. or higher and 24 ° C. or lower.

The time of the curing step [means] (Y) is preferably 72 to 336 hours. This is because when it is 72 hours or more, the flavor is improved, and when it is 336 hours or less, the change in flavor is suppressed and the improvement in flavor is maintained. More preferably, it is 96 to 192 hours, particularly preferably 96 to 168 hours, and most preferably 125 to 150 hours.

Further, in the curing step [means] (Y), it is preferable to cure the first mixture in a hermetically sealed state. This is to prevent the dissipation of flavor.

In the second mixing step [means] (M2) of adding the polysaccharide, components other than the above-mentioned polysaccharide may be further added as other second binders. Examples of such other second binders include celluloses, tamarin seed gum, gum arabic, soybean polysaccharides, karaya gum, xanthan gum, starch, cornstarch and the like. These components can be used alone or in combination of two or more.

A polysaccharide (second binder) having a solution viscosity of more than 50,000 mPa · s is preferable because it is suitable for strengthening the bond between aromatic substrates. The solution viscosity of the polysaccharide was measured using the Brookfield type viscometer described above, and a 1% by mass aqueous solution of the component was prepared, and the temperature was 10 to 30 rpm (0.17 to 0.5 s-1) in an environment of 25 ° C. ) Is the measured value where the rotation of the rotor is started and the displayed value becomes stable. The polysaccharide (second binder) may exceed 100,000 mPa · s, which is the measurement upper limit of the Brookfield type viscometer.

When a polysaccharide (second binder) is added to the aroma-generating base material to be heated, it becomes easy to mold the aroma-generating base material to be heated into a desired form in the next filling molding step [Means] (F). That is, the obtained base material for generating aroma to be heated has sufficient strength and moldability is improved. Further, the reason why it is preferable to add the polysaccharide (second binder) in the second mixing step [means] is that the mixing becomes easier and the mixture is appropriately added as compared with the addition in the first mixing step [means]. This is because it becomes easy to adjust the hardness to a high level. However, the timing of mixing the polysaccharide (second binder) is not limited to this, and the polysaccharide (second binder) may be mixed in the first mixing step [means].

Further, it is preferable that the solution viscosity of the polysaccharide (second binder) is larger than the solution viscosity of the first binder described above. By selecting such a polysaccharide (second binder), the processability (moldability) of the aroma-generating base material to be heated is improved in the filling molding step [means] (F). In particular, glucomannan has good processability (moldability) and is preferably used.

The scroll can be cut to a length of 42.0 mm with a cutter to obtain a heated aroma generator having a strip-shaped heated aroma generating base material. At this time, the mass of the aroma generating base material to be heated is 0.63 g. Assuming that the ratio of the volume of the heated aroma generating base material to the volume of the heated aroma generating body is the volume filling rate, the volume filling rate is 0.59 in the above case. As a result, the density of the aroma-generating base material to be heated, which is calculated from the volume filling rate and the mass of the aroma-generating base material to be heated, becomes ^{1.07 g / cm 3.}

As described above, the fragrance cartridge of the present invention using the fragrance-generating substrate to be heated containing microcrystalline cellulose can suppress changes over time such as a decrease in length, width, thickness and volume after production. can. As a result, in addition to being able to reduce problems such as the base material for generating heated fragrance falling off from the fragrance cartridge, changes in aerosol fluidity that affect the usability of the fragrance cartridge are suppressed, regardless of the passage of time after manufacturing. It is also effective in that it can maintain a suitable feeling of use and can be homogenized.

In addition, the characteristics of the aroma-generating substrate to be heated containing menthol and polyvinylpolypyrrolidone (water-insoluble crosslinked polymer) can be confirmed by the following method. That is, it is a method of observing how the menthol contained in the aromatic base composition or the heated aromatic generating base material is lost.

In the present invention, the prepared base material for generating aroma to be heated is precisely weighed in an environment of 17 ° C. and a relative humidity of 65% RH, and then sealed in a polyethylene bag for 24 hours or 48 hours at 5 ° C. Store in an environment. After 24 hours or 48 hours have passed, the surface of the aroma-generating substrate to be heated is observed, and the state of precipitation of white crystals is observed. The observation of white crystals means that menthol is crystallizing while sublimating from the aroma-generating substrate to be heated. Further, the mixture is placed in an environment of 17 ° C. and a relative humidity of 65% RH for 3 hours in a sealed state, then opened, and the base material for generating aroma to be heated is immediately weighed to determine the amount of change in mass. This method makes it possible to quantitatively measure how menthol is lost.

The reason for conducting the storage test in an environment of 5 ° C. is that it is a condition for suppressing the dissipation of other components of the aroma-generating base material to be heated and a good condition for evaluating the state of dissipation of menthol. In particular, to prevent white crystals from precipitating, consumers may feel uncomfortable when they see the precipitated menthol when the aromatic cartridge is packaged after manufacturing, placed on the market, and transported and stored. It also has the effect of preventing it.

In the present invention, the content of menthol in the base material for generating aroma to be heated after weighing about 5 g to 10 g in an environment of 17 ° C. and 65% RH relative humidity is d (0), and the content is d (0), and the temperature is 5 ° C. for 24 hours. The menthol reduction rate d when the mass of the aroma-generating base material to be heated after standing is d (24) and the mass of the aroma-generating base material to be heated after being left at 5 ° C. for 48 hours is d (48) is as follows. Defined by the formula of.
d = {(d (24) -d (48)} / d (0)

Here, the reason for subtracting d (48) from d (24) in the above formula is that the dissipative component other than menthol is taken into consideration, and the dissipative component from 24 hours to 48 hours is the white crystal product. This is because it better reflects the precipitation.

In the present invention, when d is 0.60 or less, precipitation of white crystals can be suppressed, which is preferable. The d is more preferably 0.50 or less, further preferably 0.30 or less, and particularly preferably 0.20 or less.

Since the above-mentioned aromatic cartridge of the present invention has a relatively large surface area, it can be said that the menthol flavor is easily produced when smoking, but the menthol is easily sublimated. However, if a heated aroma generating base material containing menthol and polyvinylpolypyrrolidone (water-insoluble crosslinked polymer) as in the present invention is used, it is effective even when the aroma cartridge has the above-mentioned shape. Sublimation of menthol can be suppressed. Further, in the production process [means], by using a lower alcohol, preferably ethyl alcohol, in which menthol is dissolved in advance, a more excellent effect of suppressing sublimation of menthol can be obtained.

FIG. 9-1 is a diagram showing an example of a heated aroma generator and a heated aroma generating base material. The heated aerosol generator (20) shown in FIG. 9-1 (A) contains a plurality of heated aerosol generating base materials (10) inside the cylindrical packaging member (30), and is heated from, for example, from the surroundings. By doing so, an aerosol containing an aroma component and the like contained in the plant used as the material of the aroma generating base material (10) to be heated is generated. For example, the heated aroma generator (20) has an outer diameter of 5.5 mm and a length of 42.0 mm. In one embodiment of the present invention, the length of the aroma generator (20) to be heated is more than 20 mm, preferably 34 mm or more. The length of the aroma generator (20) to be heated is 70 mm or less, preferably 54 mm or less, and more preferably 50 mm or less. In one embodiment of the present invention, the length of the aroma generator (20) to be heated is 10 to 70 mm, preferably 34 to 54 mm, and more preferably 34 to 50 mm.

Similarly, in one embodiment of the present invention, the length of the aroma generating substrate (10) to be heated is more than 10 mm, preferably 34 mm or more. The length of the aroma generating substrate (10) to be heated is 70 mm or less, preferably 54 mm or less, and more preferably 50 mm or less. In one embodiment of the present invention, the length of the aroma generating substrate (10) to be heated is 10 to 70 mm or less, preferably 34 to 54 mm, and more preferably 34 to 50 mm.

Each of the heated aroma generating base materials (10) filled in the heated aroma generating body (20) shown in FIG. 9-1 (B) has, for example, a length of 42.0 mm, a width of 1.5 mm, and a thickness of 0. It is formed in the shape of a strip of .3 mm and is arranged from one end to the other end in the longitudinal direction of the aroma generator (20) to be heated. As shown in FIG. 10, the longitudinal direction of the strip-shaped base material for generating aroma to be heated (10) is the aroma generator to be heated (20), the cooling region determining member (40), the filter member (50), and the mouth. It is substantially parallel to the longitudinal direction of the piece (60) and the fragrance cartridge (80). As an example, the heated aroma generator (20) is packaged with 31 strip-shaped strip-shaped heated aroma generating base materials (10) having a length of 42.0 mm, a width of 1.5 mm, and a thickness of 0.3 mm. It is a cylindrical member wound by the member (30). The longitudinal direction of the heated aroma generating base material (10) arranged inside the packaging member (30) is, for example, substantially parallel to the longitudinal direction of the heated aroma generating body (20).

The volume filling rate of the heated aroma generating base material (10) with respect to the volume of the heated aroma generating body (20) is, for example, about 0.60.

It is difficult to achieve both the removal of the heated aroma generating base material when the cartridge is attached and detached and the securing of the gas flow path when smoking. Therefore, the present inventor further presents the heated fragrance in the heated fragrance generator to the extent that there is no problem of the heated fragrance generating base material falling off when the fragrance cartridge is attached to or detached from the smoking equipment and there is no problem of combustion during suction. Even if the filling rate of the generated base material is increased, the flow path of the gas generated by heating is secured, comfortable suction is possible, and the aroma to be heated is generated so that the number of suctions per one is appropriately secured. A solution was investigated in which the base material could be filled as an aroma generator to be heated.

As a result, the shape and size of the aroma-generating base material to be heated, and the distribution and filling rate of the aroma-generating base material to be heated in the aroma-generating body are optimized, and in particular, the subject to be optimally distributed. We found that a method for producing a heated aroma generator and its manufacturing equipment were necessary, and secured a flow path for the gas generated by heating without the problem of falling off of the base material for generating a heated aroma and the problem of combustion during suction. This has led to the completion of a heated aroma generator filled with a heated aroma generating base material, which enables comfortable suction and ensures an appropriate number of suctions per bottle.

In this case, the length X of the short axis of the noodle-shaped heated aroma generating base material (23) perpendicular to the long direction is 0.3 mm, and the length Y of the long axis is 1.5 mm in the long direction. The length Z of is 240 mm, the aspect ratio between the length of the major axis and the length of the minor axis is Y: X = 5: 1, and the aspect ratio between the length in the major direction and the length of the minor axis is Z: X. = 800: 1.

However, the noodle-shaped heated aroma generating base material is not limited to the substantially rectangular parallelepiped shape shown in FIG. 9-2 (B), and the noodle-shaped heated aroma is generated as shown in FIG. 9-2 (A). A material having a substantially square vertical cross section of the base material, that is, an aspect ratio of a minor axis length to a major axis length of 1: 1 can also be used.

Further, as shown in FIGS. 9-3 (A) and 9-3 (B), it is also possible to use those having a circular and elliptical vertical cross section of the noodle-shaped heated aroma generating base material, respectively. However, in the case of such a shape, it can be produced by using an aroma generating sheet to be heated and using an extrusion molding using a circular or elliptical die, an extrusion noodle making machine or the like.

On the other hand, the outer peripheral region is covered between the noodle-shaped heated aroma generating base material alone (231), the noodle-shaped heated aroma generating base material primary aggregate (232), and the heated aroma generating base material packaging web (712). The heated aroma generator packaging web-forming gas flow path (241) is also formed, but the noodle-shaped heated aroma generating substrate primary aggregate (232) and the noodle-shaped heated aroma generating substrate secondary aggregate (234). The noodle-shaped heated aroma generating base material (23) that constitutes the noodle-shaped heated aroma generating base material (23) moves while sliding, and the surface in the long axis direction of the cross section perpendicular to the noodle-shaped heated aroma generating base material (23) is adjacent to the noodle-shaped heated aroma generating base material (23). The frequency of contact with the surface in the long axis direction of the vertical cross section of the generating base material (23) increases, and the noodle-shaped heated aroma generating base material (23) whose long axis direction is arranged in the tangential direction of the circumference. The number is large, and the filling rate of the noodle-like aroma-generating base material (23) in the outer peripheral region is high, forming a stable and strong structure.

The internal structure of the rod-shaped heated aroma generator (25) has a cross section perpendicular to the elongated direction, and the noodle-shaped heated aroma generating substrate (23) has a cross section perpendicular to the elongated direction. Since it is uniformly generated in the long direction, the structure of the cross section of the rod-shaped heated aroma generator (25) perpendicular to the long direction is uniform, and the noodle-shaped heated aroma generating base material primary agglomerate forming gas flow. The irregular gas flow path of the passage (233), the noodle-shaped heated aroma generating base material secondary agglomerate forming gas flow path (235), and the heated aroma generating body packaging web forming gas flow path (241) is rod-shaped heating. It penetrates the aroma generator (25) in the elongated direction. Therefore, the internal structures of the heated aroma generator (2) produced by cutting the rod-shaped heated aroma generator (25) and the rod-shaped heated aroma generator (25) are substantially the same.

FIG. 9-6 shows an enlarged view of a cross section of the heated aroma generator (2) perpendicular to the longitudinal direction. This is the same as the cross-sectional view of FIG. 9-5 (E), and substantially the same structure is formed in the elongated direction. Therefore, smoking using the fragrance cartridge provided with the heated fragrance generator (2) solves the problem of the conventional fragrance cartridge, and the smoke and fragrance of the aerosol are sufficiently sucked into the smoker's oral cavity. Not only is it possible to smoke comfortably, but the filling rate of the heated aroma generating base material in the outer peripheral region is higher than that in the central region, so that the pressure from the end portion and the outer peripheral portion of the heated aroma generator is applied. Because it forms a strong structure, the aroma-generating base material to be heated does not fall off when the aroma cartridge is attached or detached, ensuring an appropriate number of smokers, and also causing a problem of combustion of the aroma-generating base material to be heated during suction. It does not occur. In addition, since the filling rate in the central region is low, the fragrance cartridge can be easily inserted into the heating element of the heating type fragrance.

In the heated aroma generator (2) produced in the present embodiment, 50 noodle-shaped heated aroma generating base materials (23) are wound up by a heated aroma generator packaging member web (712). By cutting with the cutting part (9), the outer shape is about 6.9 mm and the length is 12.0 mm, the mass of which is 0.29 g, and the heated fragrance is generated with respect to the volume of the heated fragrance generator (2). The volume filling rate of the base material (21) was about 0.60, and the density of the aroma generator (2) to be heated was 1.07 g / cm ³ . Then, using the heated aroma generator thus produced, it can be applied to the aroma cartridges depicted in FIGS. 1, 2, 4 to 7, and 10 to 17, and commercially available heating can be applied. It was well suited to the formula fragrance.

As described above, the filling rate of the heated fragrance generating base material in the heated fragrance generating body is set to the extent that there is no problem of the heated fragrance generating base material falling off when the fragrance cartridge is attached to and detached from the smoking equipment and the problem of combustion during suction. Although the temperature is high, the flow path of the gas generated by heating is secured, comfortable suction is possible, and the number of times of suction per one is appropriately secured. It is not limited to this. The heated aroma generator of the present invention includes all those included in the following technical ideas.

That is, in the heated fragrance generator of the present invention, the heated fragrance generating base material is wound up by the packaging member, and the heated fragrance generating base material is aggregated in the primary aggregate to form a gas flow path in the void. The gas flow path of the void formed by the aggregate of the aroma generating base material to be heated and its primary agglomerates in the secondary agglomerates, and the aroma generating base material to be heated and its primary agglomerates come into contact with the packaging member. The gas flow path is provided with a gas flow path of the void formed in the above, and these gas flow paths have a deformed gas flow path penetrating the heated fragrance generator. Since the heated aroma generator having such a deformed gas flow path has a sufficient gas flow path, the problem of combustion of the heated aroma generating base material at the time of suction can be solved, and sufficient aerosol smoke can be obtained. And the fragrance can be sucked comfortably, and can be easily inserted into the heating element of the heating type fragrance. On the other hand, since the filling rate of the heated fragrance generating base material is high, an appropriate number of smokers can be secured, and the problem of the heated fragrance generating base material falling off when the fragrance cartridge is attached or detached does not occur.

Further, in such a deformed gas flow path, when the central region and the outer peripheral region are equally divided by the area in the cross section perpendicular to the long direction of the heated aroma generator, the central region has a porosity higher than that of the outer peripheral region. A high value is preferable for exerting the above effect.

The heated aroma generating base material constituting such a heated aroma generating body has a uniform cross-sectional shape perpendicular to the long direction in the long direction, and has a long axis of the cross section perpendicular to the long direction. The aspect ratio of the length to the length of the minor axis is preferably 1: 1 to 30: 1, more preferably 2: 1 to 20: 1, and more preferably 5: 1 to 20: 1. More preferred. However, if the aspect ratio between the length of the major axis and the length of the minor axis is larger than 30: 1, it becomes difficult to secure the gas flow path.

Further, as can be seen from this aspect ratio, the cross-sectional shape of the material to be heated that is perpendicular to the longitudinal direction is not particularly limited, and isotropic, equilateral triangles, squares, regular pentagons, etc. There is no problem even if it is a regular polygon or a circle, but in order to secure a deformed gas flow path, the aspect ratio is preferably 2: 1 or more, and it is a substantially rectangular shape and a substantially elliptical shape. Is preferable.

In particular, it is most preferable that the heat-treated aroma generating base material has a substantially rectangular parallelepiped cross-sectional shape in order to form voids and secure a gas flow path. Specifically, the length of the minor axis of the cross section perpendicular to the long direction of such a rectangular parallelepiped is preferably 0.1 to 1.0 mm, more preferably 0.1 to 0.5 mm. preferable. The length of the long axis of the cross section perpendicular to the long direction of the rectangular parallelepiped is preferably 0.5 to 3.0 mm, more preferably 0.5 to 2.0 mm.

Further, the fact that the cross-sectional shape perpendicular to the long direction of the base material for generating aroma to be heated has a uniform shape in the long direction means that the base material for generating aroma to be heated is wound up by a packaging member. It is most preferable to ensure the uniformity in the long direction of the gas flow path and to allow the gas flow path to penetrate the aroma generator to be heated.

On the other hand, the ratio of the length of the minor axis to the length in the long direction of the cross section perpendicular to the heated fragrance generating base material constituting the heated fragrance generator is determined by the chamber of the heated fragrance tool in which the fragrance cartridge is used. It depends on the size and has little causal relationship with the void ratio in the cross section perpendicular to the long direction of the aroma generator to be heated. However, in order to perform comfortable suction using the heated aroma generator having the deformed gas flow path of the present invention, there is an appropriate length, and the ratio of the length in the long direction to the length in the short axis direction is 10. : 1 to 700: 1 is preferable. Further, the specific length in the long direction of the substantially rectangular parallelepiped, which is most preferable as the base material for generating aroma to be heated, is also preferably 10 to 70 mm.

In such a heated aroma generator having anisotropy in a cross-sectional shape perpendicular to the long direction, the surface in the long axis direction in the cross section perpendicular to the long direction is the long length of the adjacent heated aroma generating base material. It is more frequently in contact with the surface in the long axis direction in the cross section perpendicular to the long direction of the adjacent aroma generating substrate than the surface in the short axis direction of the cross section perpendicular to the direction, and while securing the gas flow path, The filling rate can be increased.

Further, in such a heated aroma generator having anisotropy in a cross-sectional shape perpendicular to the long direction, the heated aroma is generated in the long axis direction of the cross section perpendicular to the long direction of the heated aroma generating base material. The number of heated aroma generating base materials arranged in the tangential direction of the circumference of the body is larger than the number of heated aroma generating base materials arranged in the normal direction of the circumference of the heated aroma generating body in this long axis direction. It is possible to increase the filling rate while securing the gas flow path.

Therefore, when a fragrance cartridge provided with such a heated fragrance generator is smoked with a heated fragrance tool, comfortable aerosol smoke and fragrance can be sucked, and at the same time, the filling rate of the heated fragrance generating base material is increased, which is appropriate. In addition to securing the number of smokers, it is possible to solve the problems of burning of the heated fragrance generating base material during suction and falling off of the heated fragrance generating base material when attaching and detaching the fragrance cartridge. It becomes easy to insert into the heating element provided in the chamber.

In order to form a heated aroma generator having a deformed gas flow path in which a gas flow path is secured despite a high filling rate of such a heated aroma generating base material, the following heated aroma generating body is required. The method of producing the aroma generator plays an important role.

That is, in the method for producing the heated fragrance generator of the present invention, the heated fragrance generating sheet has a uniform cross-sectional shape cut perpendicularly in the elongated direction in the elongated direction, which is more than twice that of the heated fragrance generator. The first step of cutting into a long noodle-shaped heated aroma generating base material, and a predetermined width of a heated aroma generating body packaging member in which a predetermined amount of noodle-shaped heated aroma generating base material is supported and conveyed by a belt. Heated aroma generator The second step of placing the packaging member on the web so as to be parallel to the long direction of the web, and the noodle-shaped heated aroma generating base material by bending the belt is the heated aroma generator. In the packaging member web, the third step of winding up the rod-shaped heated fragrance generator so as to form a columnar shape in the elongated direction, and the heated fragrance generator packaging member web of the rod-shaped heated fragrance generator manufactured in the third step in the elongated direction. It is characterized by comprising a fourth step of linearly adhering along the line and a fifth step of cutting the rod-shaped heated aroma generator produced in the fourth step to a predetermined length.

The third step of the method for producing the aroma generator to be heated is the most important step in forming a deformed gas flow path in the aroma generator to be heated. In this step, the noodle-shaped aroma generator base material to be heated is aligned in the elongated direction of the aroma generator to be heated, and is placed in the elongated direction of the packaging member web of the aroma generator to be heated which is supported and conveyed by a belt. By bending the belt, the noodle-shaped aroma generator to be heated is formed into a long rod-shaped aroma generator on the web of the aroma generator packaging member in the elongated direction so as to be columnar in the elongated direction. The internal structure of the aroma generator is determined. The deformed gas flow path with a high void ratio is formed because the noodle-shaped heated aroma is generated by the bending of the belt, and the primary aggregates gathered by moving the base material form a void, and further, the noodle-shaped heated aroma is formed. The generated base material alone and the secondary aggregates that are aggregated by the movement of the primary aggregates form voids, which form a deformed gas flow path that penetrates the heated aroma generator, and also have a noodle-like heated aroma. This is because the generation base material alone, its primary aggregate, and the packaging member form voids, which form a deformed gas flow path that penetrates the noodle-like heated aroma generator. On the other hand, the filling rate is high because the noodle-shaped heated aroma-generating base material is rolled up by the packaging member from the direction perpendicular to the long direction due to the bending of the belt in the latter half of this process, and has a long columnar rod shape. Since the heated aroma generating body is formed, the closer to the columnar shape, the more the noodle-shaped heated aroma generating base material constituting the primary and secondary aggregates of the noodle-shaped heated aroma generating base material slides. As the movement increases, the long-axis plane of the cross section perpendicular to the noodle-shaped heated aroma-generating base material comes into contact with the long-axis plane of the vertical cross-section of the adjacent noodle-shaped heated aroma-generating base material. This is because the number of noodle-shaped heated aroma generating base materials arranged in the tangential direction of the circumference of the cylinder in the long axis direction also increases. Then, the filled state of the noodle-like heated aroma generating base material in the outer peripheral region forms a stable and strong structure. On the contrary, in the central region of the rod-shaped heated aroma generator, the bulky primary agglomerates and secondary agglomerates described above remain, so that the deformed gas flow path formed in the primary agglomerates and the secondary agglomerates remains. The porosity of the central region is higher than that of the outer peripheral region. The heated fragrance generator used in the fragrance cartridge is obtained by cutting the rod-shaped heated fragrance generator whose internal structure is formed in this way, and has an internal structure exactly the same as such an internal structure. ing.

That is, the noodle-shaped heated aroma generating base material, which is longer than the length in the long direction of the heated aroma generator and has substantially the same cross-sectional shape, is formed into a roll-shaped long web of the heated aroma generator packaging member web. Since it is placed in the direction and rolled into a cylinder in the elongated direction, the deformed gas flow path of the rod-shaped heated aroma generator becomes a through hole, and in the process of rolling, the noodle-shaped heated aroma generating base material becomes a cylinder. As the primary and secondary aggregates are formed, a deformed gas flow path can be formed in itself, and a deformed gas flow path can be formed with the packaging member. Further, in this process, the primary aggregate and the secondary aggregate remain in the central region of the columnar rod-shaped aroma generating substrate to be heated, but in the outer peripheral region, the vertical cross section of the noodle-shaped aroma generating substrate to be heated is formed. The major axis direction is more frequently in contact with the long axis direction of the vertical cross section of the adjacent noodle-shaped heated aroma generating base material, and the proportion of the cylinders arranged in the tangential direction around the cylinder is increased to increase the filling rate. ..

In order to control such behavior, the shape of the noodle-shaped heated aroma generating base material is important, and the noodle-shaped heated aroma generating base material cut in the first step is perpendicular to the elongated direction. The aspect ratio between the length of the major axis and the length of the minor axis of the cross section is 1: 1 to 30: 1, and the aspect ratio between the length in the major direction and the length of this minor axis is 40: 1-3600: 1. It is preferable to have. In particular, the aspect ratio between the length of the major axis and the length of the minor axis is more preferably 2: 1 to 20: 1, and even more preferably 5: 1 to 20: 1. These aspect ratios are closely related to the degree of mobility when the noodle-shaped heated aroma-generating base materials arranged in the long direction are formed into a columnar shape so as to wrap them in the direction perpendicular to the long direction. The filling rate can be increased while securing the gas flow path. Therefore, the aspect ratio between the length of the major axis and the length of the minor axis of the cross section perpendicular to the elongated direction exceeds 30: 1, and the aspect ratio of the length in the elongated direction and the length of the minor axis exceeds 3600: 1. As a result, the frequency with which the noodle-shaped heated aroma generator comes into contact with the surface in the long axis direction becomes high, and the degree of mobility is extremely lowered, making it difficult to form a primary agglomerate and a secondary agglomerate. Further, when the aspect ratio of the length of the major axis to the length of the minor axis is 1: 1, the noodle-shaped heated aroma generators may be arranged like a close-packed structure depending on the production conditions. ..

There is no problem even if the shape of the cross section of the noodle-shaped heated aroma generating base material perpendicular to the long direction is an isotropic, regular polygon such as a regular triangle, a square, and a regular pentagon, or a circle. However, in forming a deformed gas flow path, it is more preferably a rectangle or an ellipse having a minor axis and a major axis, and even more preferably a substantially rectangular shape.

Further, in the third step of rolling the noodle-shaped heated aroma generating base material of the present invention into a cylinder in the long direction, a guide provided with a groove capable of gradually bending the belt into a cylinder is provided together with the belt. It is characterized in that it passes through a packaging member that is supported and conveyed by a belt and a noodle-shaped heated aroma generating base material that is placed on the packaging member. This belt can also utilize, for example, ganiture tape used in cigarettes.

As is clear from the above, when the central region and the outer peripheral region are equally divided by the area in the cross section perpendicular to the long direction of the rod-shaped heated aroma generator, the central region has a higher porosity than the outer peripheral region. This state is directly reflected in the heated aroma generator provided in the aroma cartridge.

This is because the noodle-shaped heated aroma generating base material having an anisotropic cross-sectional shape perpendicular to the long direction is rolled up by the packaging member to form the primary and secondary agglomerates in the long direction. The surface in the long axis direction in the cross section perpendicular to is more than the surface in the minor axis direction in the cross section perpendicular to the long direction of the adjacent noodle-shaped heated aroma generating base material. It is closely related to the high frequency of contact with the surface in the long axis direction in the cross section perpendicular to the long direction. Further, in this process, the noodle-shaped heated aroma generating base material in which the long axis direction of the cross section perpendicular to the long direction of the noodle-shaped heated aroma generating base material is arranged in the tangential direction of the circumference of the rod-shaped heated aroma generating base material. It is also closely related to the fact that the number of the noodle-shaped heated aroma generators can be larger than the number of noodle-shaped heated aroma generators arranged in the normal direction of the circumference of the rod-shaped heated aroma generator. ..

As described above, the shape of the noodle-shaped heated aroma generating base material has a great influence on the structure of the cross section of the rod-shaped heated aroma generating body perpendicular to the long direction, but the belt transport speed. , It is also possible to control by the shape of the guide.

Further, in order to easily and easily bond the heated fragrance generator packaging member in the long direction, a predetermined amount of hot is placed at a predetermined position on the heated fragrance generator packaging member web in parallel with the first step. It is preferable to add a step of applying the melt adhesive and to provide a heating means in the fourth step.

Then, the method for producing the aroma generator to be heated can be continuously produced by the following apparatus. That is, the apparatus for producing a heated aroma generator of the present invention includes a noodle-shaped heated aroma generating base material supply device in which a heated aroma generating sheet is cut, a heating aroma generator packaging member web supply device, and the like. An endless belt drive device that supports and conveys the heated fragrance generator packaging member web, a guide having a plurality of grooves provided in the endless belt transport path, an adhesive device for the heated fragrance generator packaging member web, and noodles. The base material for generating aroma to be heated is continuously driven by a cutting machine for a rod-shaped aroma generator to be heated, which is wound up by a web of a packaging member for the aroma generator to be heated. Here, the grooves of the plurality of guides are provided with 3 to 4 different guides so as to form a columnar shape in a stepwise manner from a groove of about a crescent moon to a groove of about a half moon to a groove close to a full moon. It is preferable to have.

In addition, the apparatus for producing a heated aroma generator of the present invention simplifies the bonding process of the packaged member for a heated aroma generator, and supplies a noodle-shaped aroma generating base material in which the heated aroma generating sheet is cut. A device, a supply device for a heated aroma generator packaging member web to which a predetermined amount of hot melt adhesive is applied at a predetermined position, a drive device for an endless belt that supports and conveys a heated aroma generator packaging member web, and the like. A guide having a plurality of grooves provided in the endless belt transport path, a heating device for the heated aroma generator packaging member web, and a noodle-shaped heated aroma generating base material are wound up by the heated aroma generator packaging member web. It is more preferable that the rod-shaped heated aroma generator and the cutting machine are continuously driven.

The heated fragrance generator as described above is used as the heated fragrance generator (20, 110) depicted in FIGS. 1, 2, 4 to 7, and 10 to 17. In particular, FIGS. 10 to 14 show examples of various fragrance cartridges in which a heated fragrance generator (20), a cooling member (40), a filter member (50), and a mouthpiece (60) are connected in this order. In 15 and 16, an example of an aromatic cartridge in which the mouthpiece is replaced by the filter member (50) is drawn.

The cooling region determining member (40) shown in FIG. 10 is wound into a cylindrical shape having an outer diameter of 5.5 mm and a length of 25 mm, which is adjacent to the heated aroma generator (20) on the upstream side U. It is thick paper.

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

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

The outer diameters of the aroma generator (20) to be heated, the cooling region determining member (40), the filter member (50), and the mouthpiece (60) are preferably 4.7 to 6.1 mm. The heated aroma generator having such an outer diameter is preferably used for a smoking tool main body that heats from the periphery of the heated aroma generator. This is because the heat obtained from the surroundings is efficiently transferred to the entire heated aroma generator. Since the cross section of an article for smoking is usually circular, it is expressed as "outer diameter", but assuming that the cross section is, for example, a rectangle, it is preferable to express it by the perimeter. In that case, the peripheral length is 14.8 to 19.2 mm.

The heated aroma generator (20), the cooling region determining member (40), the filter member (50), and the mouthpiece (60) are packaged by the packaging member (70).

The dimensions shown in FIGS. 9-1 and 10 are merely examples, and dimensions other than these may be used.

FIG. 11 is a schematic cross-sectional view showing a usage pattern of the fragrance cartridge (80).

The fragrance cartridge (80) is attached to the smoking device main body (90) for use. The smoking tool main body (90) uses electric power supplied from a battery (not shown) arranged in the smoking tool main body (90) to generate a heated fragrance generator (20) portion of the fragrance cartridge (80). Heat from its surroundings. An aerosol containing an aromatic component is generated from the heated aromatic generator (20), and the generated aerosol moves from the upstream U side to the downstream D side and reaches the user from the mouthpiece (60) portion. Be sucked.

The aerosol is cooled as it passes through the inside of the cooling region determining member (40), which is a cardboard wound in a cylindrical shape. That is, the inside of the cooling region determining member (40) is a cooling region for cooling the aerosol. The cooling region is determined by the cooling region determining member (40). The filter member (50) removes, for example, fine particles contained in the gas sucked by the user.

12 to 16 are schematic perspective views showing a fragrance cartridge according to a modified example.

One of the embodiments will be described with reference to the first modification. FIG. 12 shows a schematic perspective view of the fragrance cartridge according to the first modification.

In the fragrance cartridge (80) according to the first modification, a plurality of fragrance cartridges are provided at the corresponding positions of the packaging member (70) and the filter member (50) at equal intervals along the circumferential direction of the filter member (50). Hole (ventilation area) (50a) is formed. The hole (50a) penetrates the packaging member (70), and the filter member (50) is formed with a recess. The hole (50a) is drilled at a distance of 2 mm from one end side of the filter member (50). The number of holes (50a) is, for example, 12 to 36, and 24 as an example.

Since the holes (50a) are formed in the filter member (50), the user can more easily suck the aerosol containing the aromatic component, and when the user sucks the aerosol from the mouthpiece (60), the cooling region determining member The aerosol containing the natural fragrance of the aromatic substrate retained in the cooling region determined by (40) is cooled with the outside air flowing in from the pores (50a), resulting in the intake of finer aerosol particles by the user. It is expected that the aerosol will be well dispersed in the aerosol, and that the aerosol generated in this way will be well suited for enjoying the aroma. In addition, the user can more easily inhale the aerosol containing the aromatic component, and can further avoid inhaling the high-temperature aerosol by the user, so that the user can further enjoy the natural aroma of the aromatic base material. It becomes an aerosol cartridge that can be used.

One of the embodiments will be described with reference to a second modification. FIG. 8 shows a schematic perspective view of the fragrance cartridge according to the second modification.

In the first modification, a plurality of holes (50a) are formed at equal intervals along the circumferential direction of the filter member (50) at the corresponding positions of the packaging member (70) and the filter member (50). In the second modification, a plurality of holes (ventilation regions) (50b) at equal intervals along the circumferential direction of the cooling region determining member (40) at the corresponding positions of the packaging member (70) and the cooling region determining member (40). ) Is formed. The hole (50b) is a through hole that penetrates the thick paper constituting the packaging member (70) and the cooling region determining member (40). The hole (50b) is drilled at a distance of 2 mm from the other end side of the cooling region determining member (40). The number of holes (50b) is, for example, 12 to 36, and 24 as an example.

Since the filter member (50) is formed with a hole (50b), when the user sucks from the mouthpiece, the natural aromatic base material stays in the cooling region determined by the cooling region determining member (40). As a result of the aerosol containing aroma being strongly agitated and cooled together with the outside air flowing in from the pores (50b), it is expected that the finer aerosol will be better dispersed in the intake air sucked by the user. It is expected that the aerosol generated in will be better suited for enjoying the aroma. In addition, the user can more easily inhale the aerosol containing the aromatic component, and can further avoid inhaling the high-temperature aerosol by the user, so that the user can further enjoy the natural aroma of the aromatic base material. It becomes an aerosol cartridge that can be used.

Further, in another embodiment of the second modification, the mouthpiece (60) made of thick paper wound in a cylindrical shape in the fragrance cartridge according to the second modification is not included. For example, with reference to FIG. 15, the mouthpiece region (50 m) that the user sucks with his / her mouth is determined in the downstream D side region of the filter member (50). The length of the filter member (50) composed of the cellulose acetate fiber formed into a cylindrical shape is set to 8 mm in the second modification, but is set to 16 mm in another embodiment of the second modification.

Further, in another embodiment of the second modification, the mouthpiece (60) made of thick paper wound in a cylindrical shape in the fragrance cartridge according to the second modification is not included. For example, with reference to FIG. 15, the mouthpiece region (50 m) that the user sucks with his / her mouth is determined in the downstream D side region of the filter member (50). In the second modification, the cooling region determining member (40) is set to 25 mm, but in another embodiment of the second modification, it is set to 30 to 35 mm, for example, 31 mm, and the length of the filter member (50) is set to, for example, 10 mm. Examples thereof include. Since the cooling region determining member (40) can be taken for a long time, there is an advantage that the natural aroma and taste of the aromatic base material can be stably obtained even if a large amount of suction is taken.

One of the embodiments will be described with reference to a third modification. FIG. 14 shows a schematic perspective view of the fragrance cartridge according to the third modification.

In the fragrance cartridge (80) according to the third modification, a plurality of fragrance cartridges are provided at the corresponding positions of the packaging member (70) and the filter member (50) at equal intervals along the circumferential direction of the filter member (50). Holes (50a) are formed, and a plurality of holes (50b) are formed at equal intervals along the circumferential direction of the cooling region determining member (40) at corresponding positions of the packaging member (70) and the cooling region determining member (40). ) Is formed. The hole (50a) is drilled at a distance of 2 mm from one end side of the filter member (50). The hole (50b) is drilled at a distance of 2 mm from the other end side of the cooling region determining member (40).

Therefore, when the user sucks from the mouthpiece, the aerosol containing the natural aroma of the aromatic base material staying in the cooling region determined by the cooling region determining member (40) is combined with the outside air flowing in from the hole (50b). In addition to being strongly agitated and cooled, as a result of being cooled together with the outside air flowing in from the pores (50a), the effect of making finer aerosol particles into a very good dispersed state during the intake air sucked by the user is synergistic. It is expected that the aerosol generated in this way will be very suitable for enjoying the aroma. In addition, the user can more easily suck the aerosol containing the aromatic component, and can further avoid sucking the high temperature aerosol by the user. Therefore, in the first and second modifications, the aromatic group is more likely to be sucked. It becomes an fragrance cartridge that allows you to further enjoy the natural fragrance of the material.

One of the embodiments will be described with reference to a fourth modification. FIG. 15 shows a schematic perspective view of the fragrance cartridge according to the fourth modification.

The fragrance cartridge according to the fourth modification does not include the mouthpiece (60) made of cardboard wound in a cylindrical shape in the embodiment. The mouthpiece region (50 m) that the user sucks with his mouth is determined in the downstream D-side region of the filter member (50). In the fourth modification, the length of the filter member (50) made of cellulose acetate fibers formed into a cylindrical shape is, for example, 16 mm.

The fragrance cartridge according to the fourth modification includes a heated fragrance generator (20), a cooling region determining member (40), and a filter member (50), which are arranged adjacent to each other in this order. The fragrance cartridge has a cylindrical appearance with an outer diameter of 5.5 mm and a length of 83 mm.

If the mouthpiece (60) made of thick paper wound in a cylindrical shape is not included and the filter member (50) is used instead, the number of parts will be reduced and the assembly man-hours will be reduced in creating the aromatic cartridge. Can be done.

Further, as another embodiment of the fourth modification, an embodiment in which the cooling region determining member (40) is 31 mm and the length of the filter member (50) is, for example, 10 mm can be mentioned. Since the cooling region determining member (40) can be taken for a long time, there is an advantage that the natural aroma and taste of the aromatic base material can be stably obtained even if a large amount of suction is taken.

Further, as another embodiment of the fourth modification, there is an embodiment in which the cooling region determining member (40) is set to less than 10 to 15 mm. For example, an embodiment in which the cooling region determining member (40) is 14 mm and the length of the filter member (50) is 27 mm can be mentioned. When the cooling region determining member (40) is shortened, there is an advantage that the natural aroma and taste of the aromatic base material can be sufficiently obtained from the first smoking operation.

One of the embodiments will be described with reference to the fifth modification. FIG. 16 shows a schematic perspective view of the fragrance cartridge according to the fifth modification.

The fragrance cartridge according to the fifth modification is a plurality of fragrance cartridges according to the fourth modification at the corresponding positions of the packaging member (70) and the filter member (50) at equal intervals along the circumferential direction of the filter member (50). It differs from the fourth modification in that the hole (50a) is formed. The hole (50a) is formed in the vicinity of the side end portion of the cooling region determining member (40). The hole (50a) penetrates the packaging member (70), and the filter member (50) is formed with a recess. The hole (50a) is drilled at a distance of 2 mm from one end of the filter member (50). The number of holes (50a) is, for example, 12 to 36, and 24 as an example.

Since the holes (50a) are formed in the filter member (50), the user can more easily suck the aerosol containing the aromatic component, and when the user sucks the aerosol from the mouthpiece, the cooling region determining member (40) The aerosol containing the natural fragrance of the aromatic substrate retained in the cooling region determined by is better during inspiration when the user inhales finer aerosol particles as a result of being cooled with the outside air flowing in through the pores (50a). It is expected that the aerosol will be dispersed in the air, and that the aerosol generated in this way will be well suited for enjoying the aroma. In addition, the user can more easily inhale the aerosol containing the aromatic component, and can further avoid inhaling the high-temperature aerosol by the user, so that the user can further enjoy the natural aroma of the aromatic base material. It becomes an aerosol cartridge that can be used.

If the mouthpiece (60) made of thick paper wound in a cylindrical shape is not included and the filter member (50) is used instead, the number of parts will be reduced and the assembly man-hours will be reduced in creating the aromatic cartridge. Can be done.

Further, as another embodiment of the fifth modification, an embodiment in which the cooling region determining member (40) is 31 mm and the length of the filter member (50) is, for example, 10 mm can be mentioned. Since the cooling region determining member (40) can be taken for a long time, there is an advantage that the natural aroma and taste of the aromatic base material can be stably obtained even if a large amount of suction is taken.

Further, as another embodiment of the fifth modification, there is an embodiment in which the cooling region determining member (40) is set to less than 10 to 15 mm. For example, an embodiment in which the cooling region determining member (40) is 14 mm and the length of the filter member (50) is 27 mm can be mentioned. When the cooling region determining member (40) is shortened, there is an advantage that the natural aroma and taste of the aromatic base material can be sufficiently obtained from the first smoking operation.

As shown in FIGS. 15 and 16, in the fragrance cartridges according to the fourth and fifth modifications, the length of the cooling region determining member (40) is 25 mm and the length of the filter member (50) is 16 mm. The lengths of the cooling region determining member (40) and the filter member (50) can be changed as appropriate. For example, under the condition that the total length of the cooling region determining member (40) and the filter member (50) is 41 mm, the length of the cooling region determining member (40) is 10 to 35 mm, and the length of the filter member (50) is 10. The length can be 6 to 31 mm or the like. It is also possible to independently set the length of the cooling region determining member (40) to 10 mm or more. This is because if the length of the cooling region determining member (40) is 10 mm or more, the cooling capacity is sufficient and can be secured.

When the length of the cooling region determining member (40) is 10 mm or more and less than 15 mm, there is an advantage that the natural aroma and taste of the aromatic base material can be sufficiently obtained from the first smoking operation, and when it is 15 to 30 mm, there is an advantage. It is possible to stably obtain the natural aroma and taste of the aromatic base material during the smoking operation after the beginning of smoking, and when it exceeds 30 mm, the natural aroma and taste of the aromatic base material can be stably obtained even if a large inhalation is made. There is an advantage that it can be used. However, when it exceeds 30 mm, it is preferably 45 mm or less, and more preferably 35 mm or less. This is because when the length of the cooling region determining member (40) is 45 mm or less, a preferable cooling state can be obtained, and when it is 35 mm or less, a more preferable cooling state can be obtained.

When the position for drilling the hole (50a) in the filter member (50) is provided in a region within 4 mm from one end side of the filter member (50), the result is that the filter member (50) is cooled together with the outside air flowing in from the hole (50a). As a result, it is easy to make the finer aerosol particles well dispersed during the intake air sucked by the user, and it is preferable to provide the finer aerosol particles in a region of 2.5 mm or less because the dispersed state can be achieved more effectively.

Regarding the position where the hole (50b) is drilled in the cooling region determining member (40), if it is provided in a region within 4 mm from the other end side of the cooling region determining member (40), it is provided together with the outside air flowing in from the hole (50b). As a result of strong agitation and cooling, it is easy to make the finer aerosol more well dispersed during the intake air sucked by the user, and if it is provided within 2.5 mm from the other end, it is more effectively and well dispersed. Is preferable because it can achieve.

Although the present invention has been described above with reference to Examples and Modifications, the present invention is not limited thereto. For example, in the examples and modifications, a strip-shaped substrate for generating aroma to be heated (10) having a length of 42 mm, a width of 1.5 mm, and a thickness of 0.3 mm was used. A strip-shaped base material for generating aroma to be heated, which has a width of 0.5 to 3.0 mm and a thickness of 0.1 to 0.5 mm, can be used. Further, in the case of a rod shape, it is possible to use a base material for generating aroma to be heated having a length of 20 to 54 mm and an outer diameter of 0.2 to 3.0 mm. Further, as another example, the length of the strip-shaped or rod-shaped filling material can be 34 mm or more, preferably 50 mm or less, and preferably 34 to 50 mm. The strip-shaped or rod-shaped filling as described above is preferable because when heated in the smoking device body, an aerosol containing an aromatic component of an aromatic base material is likely to be generated.

Further, the heated aroma generating base material contains an aromatic base material and an aerosol former that are the source of the aroma, and contains 30% by mass or more and 90% by mass or less of the aromatic base material that is the source of the aroma, and the aerosol. An aerosol former containing 5% by mass or more and 40% by mass or less of a former, and 0.12 g or more of an aromatic base material which is a source of aroma in the heated aromatic generator having the heated aromatic base material. When it is configured to contain 0.02 g or more of, an fragrance cartridge capable of enjoying the natural fragrance of the fragrance base material can be obtained.

In the present specification, the "rod-shaped base material for generating aroma to be heated" is a base material having a shape having a longitudinal direction and having a perfect circular or elliptical cross section in the direction orthogonal to the longitudinal direction. Say something. Further, in the "rod-shaped base material for generating aroma to be heated", the "outer diameter" means the diameter when the cross section has a perfect circular shape, and the length of the major axis when the cross section has an elliptical shape. Further, in the present specification, even if the cross section in the direction orthogonal to the longitudinal direction is a polygon, it is a "rod-shaped base material for generating aroma to be heated", and is within one or two or more circles circumscribing the polygon. , The diameter of the circumscribed circle having the largest diameter is defined as the "outer diameter".

Further, in the examples and modifications, the heated fragrance generator (20) in which the heated fragrance generating base material (10) was wrapped with the packaging member (30) was used, but the packaging member (70) was heated. It may be configured to also serve as a packaging member (30) around which the aroma generating base material (10) is wound. The stable airflow of the aerosol makes it easier for the user to inhale the aromatic components.

Further, in the aroma cartridges according to the examples and modifications, the lid may be arranged on the upstream U side of the aroma generator (20) to be heated. As a result, it is possible to suppress the dissipation of the fragrance of the fragrance generating base material (10) to be heated, and prevent the fragrance generating base material (10) to be heated from falling off from the fragrance cartridge when, for example, transporting the fragrance cartridge. It is possible. The lid can be formed of a filter, paper, sponge or the like. Further, the lid can be arranged on the downstream D side of the heated aroma generator (20).

Further, the first and second binders may also serve as an aromatic base material that is a source of aroma.

Further, in the embodiment, the heated aroma generator (20), the cooling region determining member (40), the filter member (50), and the mouthpiece (60) are arranged adjacent to each other in this order, and a packaging member such as tobacco paper is arranged. The fragrance cartridge was manufactured by winding with (70), but in the packaging member (70) formed into a cylindrical shape in advance, the fragrance generator to be heated (20), the cooling region determining member (40), the filter member (50), Further, the mouthpiece (60) can be inserted and manufactured so as to be arranged in this order. It is also possible to manufacture by inserting the remaining members after winding a part of the members with the packaging member (70). As an example, the fragrance cartridge (see FIG. 15) according to the fourth modification comprises a 42 mm long heated fragrance generator (20), a 25 mm long cooling region determining member (40), and a 83 mm long packaging member (see FIG. 15). After winding with 70), it is possible to insert and manufacture a filter member (50) having a length of 16 mm.

Further, in the production of the fragrance cartridge according to the embodiment, the heated fragrance generator (20) (length 42 mm), the cooling region determining member (40) (length 25 mm), the filter member (50) (length 8 mm), The mouthpiece (60) (length 8 mm) was wound with a packaging member (70) having a length of 83 mm, which is the sum of the lengths of these members, but the length was shorter than the sum of the lengths of these members. It may be wrapped with the packaging member (70) of. For example, as shown in FIG. 17, all of the mouthpiece (60) (length 8 mm), the filter member (50) (length 8 mm), and the cooling region determining member (40) (length 25 mm) and the fragrance to be heated. An aromatic cartridge can be manufactured by winding it with a packaging member (70) having a length that covers a part of the generator (20).

In the fragrance cartridges according to the examples and modifications in which a plurality of strip-shaped base materials for generating fragrance to be heated are arranged so as to align their longitudinal directions, for example, when the fragrance generator to be heated is attached to the smoking device main body, the fragrance generator to be heated ( The problem that the heated aroma generating base material (10) contained in 20) is broken and hinders its use is alleviated. In order to make the heated aroma generating base material (10) hard to break, when the heated aroma generating base material (10) is in the shape of a strip, 9 or more of them are included in the heated aroma generating body (20) and are rod-shaped. In some cases, it is preferable to include 15 or more in the aroma generator (20) to be heated.

Further, if the length of such a rod-shaped or strip-shaped filling material is substantially equal to the length of the aroma generator (20) to be heated, it becomes more difficult to break.

In addition, it will be obvious to those skilled in the art that various changes, improvements, combinations, etc. are possible.
