Hereinafter, embodiments of the present invention will be described with reference to the attached drawings. The present invention is not limited to the following embodiments. In the description of the drawings, the same elements are designated by the same reference numerals, and duplicate description will be omitted. In addition, the dimensional ratios in the drawings are exaggerated for convenience of explanation and may differ from the actual ratios.

FIG. 6 is a flow chart showing a process of a method for producing a non-tobacco plant composition and a filling for electronic cigarettes in an embodiment to which the present invention is applied.

This method includes a drying / crushing step (A) of drying / crushing a non-tobacco plant or the like that is a source of aroma. If the raw material can be used as it is, such a step can be omitted.

Further, after the step of weighing the menthol, the lower alcohol and the water-insoluble crosslinked polymer (B1), the menthol dissolving step (B2) of mixing the weighed menthol, the lower alcohol and the water-insoluble crosslinked polymer to dissolve the menthol is provided. The non-tobacco plant composition is obtained through a mixing step (M) of mixing with other materials such as an aerosol former for preparing the non-tobacco plant composition.

The non-tobacco plant composition can be formed into a desired shape through the filling molding step (F). The non-cigarette plant composition having a desired shape is subjected to the electronic cigarette cartridge manufacturing step (G) as a filling material for electronic cigarettes to obtain an electronic cigarette cartridge.
Each process will be described in order. Although the description has been divided into the above steps for the purpose of explaining the invention, it also includes performing two or more steps at the same time. The details of the non-tobacco plant used as a raw material will be described later.

First, in the drying / crushing step (A), desired crushing is performed in order to obtain a non-tobacco plant composition from a part of the non-tobacco plant used as a raw material (for example, leaves, seeds, dried fruits, stems, bark, roots, etc.). Process into a thing. At that time, it is also preferable to adjust the amount of water so as to be convenient for absorbing or supporting the aerosol former, water and other components to be added later.
The drying temperature is preferably 60 ° C. or higher and 80 ° C. or lower. Within this range, it is easy to reach the desired amount of water while avoiding the dissipation of the required flavor component. When the temperature is 65 ° C. or higher, the desired amount of water can be reached more easily, and when the temperature is 75 ° C. or lower, the required flavor component can be further prevented from being dissipated.

The water content after drying and crushing is preferably 5% by mass or less. By doing so, it becomes easy to make a slurry in a later process. It is more preferably 3% by mass or less. Further, when the water content is preferably 0.1% by mass or more, it is possible to maintain a state of good compatibility with water or the like.
Further, the drying / crushing step (A) can be provided with a sieving step for sieving the dried pulverized product, and can be put into the mixing step (M) with a desired particle size.

After the weighing step (B1), the process proceeds to the menthol dissolving step (B2) in which the menthol, the lower alcohol and the water-insoluble crosslinked polymer are mixed and the menthol is dissolved. Is mixed and dissolved. Preferably, the menthol is dissolved in a lower alcohol, and then the water-insoluble crosslinked polymer is added and mixed.
Here, menthol is not limited to those obtained from natural products, but may be synthetic products. In addition, lightly loaded, mint, peppermint oil and other substances containing menthol may be used. The lower alcohol is a solvent that dissolves menthol, and ethyl alcohol is particularly preferably used.

In the present invention, the water-insoluble crosslinked polymer is intended to be a non-crosslinked polymer that is soluble in water and is crosslinked to become insoluble in water and swell. Of course, it is preferable that it does not dissolve in lower alcohol and swells, and such a substance is selected. Such a water-insoluble crosslinked polymer has a hydrophilic portion and a hydrophobic portion, and the hydrophilic portion contributes to swelling and the hydrophilic portion is oriented toward menthol to exert the effect of the present invention. I believe. Preferred examples are polyvinylpolypyrrolidone, which is a crosslinked product of polyvinylpyrrolidone, and crosslinked polysaccharides in which water-soluble polysaccharides are crosslinked to make them water-insoluble, such as crosslinked polysaccharides with epoxy, ester-linked, and ether-linked. Is given as an example.
In the present invention, particularly good results are obtained when ethanol and polyvinylpolypyrrolidone are used together with menthol.

As for the amount of menthol added, it is sufficient to add an amount targeting the desired flavor. In order to flavor menthol, the content in the filling for electronic cigarette is 0.1% by mass or more and 10% by mass or less as a guide. Preferably, 0.2% by mass or more and 5% by mass or less is another guideline.

In preparing the non-tobacco plant composition, the amount of the water-insoluble crosslinked polymer added is preferably in the range of 10 parts by mass or more and 2000 parts by mass or less, and further 50 parts by mass or more and 600 parts by mass with respect to 100 parts by mass of menthol. The following is more preferable. In other words, the content of the water-insoluble crosslinked polymer is 0.1 times or more and 20 times or less, preferably 0.5 times or more and 6 times or less, based on the content of menthol.

In order to obtain the effect of the present invention, the water-insoluble crosslinked polymer is preferably present in an amount of 2% by mass or more, preferably 4% by mass or more, even if it is the smallest, in the filling for electronic cigarettes. The presence of such an amount is preferable in that the effect of the present invention is exhibited with respect to long-term storage stability. Further, a range not exceeding 10% by mass is preferable. This is because if it is within 10% by mass, the flavor derived from non-plant-derived polyphenols and the like can be maintained.

The lower alcohol used is preferably 50 parts by mass or more with respect to 100 parts by mass of menthol. Further, when the amount is 100 parts by mass or more, there is an effect that the mixing of the water-insoluble crosslinked polymer can be sufficiently effective while dissolving the menthol. When it is 2000 parts by mass or less, the residual lower alcohol can be reduced in the subsequent step, so that the manufacturing process can be efficient.

Next, the mixing step (M) for mixing will be described.

The aerosol former, flavor additive, preservative, binder, thickener and the like exemplified above are prepared as others in FIG. 6 and proceed to the mixing step (M).

In the mixing step (M), a normal mixer can be used. For example, a form in which the materials in the mixing tank are mixed while applying a shearing force with a stirring blade is preferably used.

A crushed and dried product of a non-tobacco plant, an aerosol former, a menthol solution that has undergone the menthol dissolution step (B2), a binder or a thickener, and water or the like are mixed, if necessary. In this way, a non-tobacco plant composition can be obtained.

Next, in the filling molding step (F), a method of passing the non-tobacco plant composition through an orifice by pressure to form a rod, a method of molding into a thin sheet, or a method of drying and pulverizing the non-tobacco plant composition. For example, it can be granulated by doing the above.

In the present invention, a method of molding into a thin sheet and then molding by cutting will be described in detail. A three-roll mill was prepared to make a thin sheet. When a three-roll mill is used, it is possible to obtain a sheet having a desired thickness by a doctor blade while performing kneading and dispersion by compression by being pushed between narrow rolls and shearing due to a difference in roll speed. ,preferable. It is also preferable to use a press roller or a press machine.

Further, in the filling molding step (F), flavor additives, preservatives, etc. such as non-tobacco plants, aerosol formers, binders or thickeners may be added, or water or the like may be added, if necessary. It may be added.

In the present invention, although it is described as water, it is preferable to use water obtained by sterilization or removal of microorganisms, and pure water obtained by reverse osmosis membrane or ion exchange is used. It is preferable to use it.

The thickness of the sheet obtained in the filling molding step (F) is preferably 0.1 mm or more and 1.0 mm or less, and more preferably 0.1 mm or more and 0.5 mm or less. The obtained sheet is cut into a desired shape, and examples thereof include a cutter and a rotary blade type rotary cutter for cutting.

As a specific example of the filling forming step (F), a sheet having a thickness of 0.3 mm is cut into a desired shape. For example, it is cut into a rectangle having a length of 150 mm and a width of 240 mm. This sheet is supplied to a rotary cutter and cut into a shape of 1.5 mm in length and 240 mm in width to obtain a sheet cut product. 50 sheets of the cut sheet are wrapped with tobacco paper to prepare a roll having an outer diameter of about 6.9 mm. The scroll can be cut to a length of 12.0 mm with a cutter to obtain an aerosol-forming base material (110). At this time, the mass of the filling material is 0.29 g. When the ratio of the volume of the filling material to the volume of the aerosol-forming base material (110) is referred to as the volume filling rate, the volume filling rate is 0.60 in the above case. Then, the density of the filling material calculated from the volume filling rate and the mass of the filling material is 1.07 g / cm3.

In the case of the filling molding step (F) described above, a plurality of rod-shaped or strip-shaped fillings are arranged along the longitudinal direction of the electronic cigarette cartridge. Further, the plurality of rod-shaped or strip-shaped fillings are included by an inclusion member (151) such as tobacco paper along the axis of the roll height to form an aerosol-forming base material (110).

The electronic cigarette cartridge manufacturing process (G) will be described. The aerosol-forming base material (110) thus obtained, the support element (300) described in detail below, and the mouthpiece (140) are wound with the packaging member (150), or the packaging member (preliminary). 150) is made into a cylindrical shape, and is made by inserting a mouthpiece (140), a support element (300), and a filling material (110).
Therefore, as an example of a suitable configuration of the present invention, an electronic cigarette having an aerosol-forming base material (110), a support element (300), and a mouthpiece (140) from the upstream side (10) to the downstream side (20). Examples include cartridges.

When the heating element of the main body of the electronic cigarette of the present invention is inserted and used, the effect of suppressing the sublimation of menthol can be sufficiently exhibited even in a preferable form. Examples of such a form include a filling molded into a shape having a length of 10 mm or more and 20 mm or less, a width of 1.1 mm or more and 2.0 mm or less, and a thickness of 0.1 mm or more and 0.5 mm or less. Since such a shape has a relatively large surface area, it can be said that the menthol flavor is easily produced when smoking, but the sublimation is easy.

When a filling for an electronic cigarette containing menthol and a water-insoluble crosslinked polymer, preferably polyvinylpolypyrrolidone, is used, sublimation of menthol can be effectively suppressed even in the case of the above shape. Further better results can be obtained by adding a lower alcohol, preferably ethanol in which menthol is dissolved, in advance in the production process.

The characteristics of the filling material for electronic cigarettes created as described above can be confirmed as follows. The loss of menthol contained in the non-tobacco plant composition or e-cigarette filling may be observed.

In the present invention, the prepared non-cigarette plant composition or electronic cigarette filling is precisely weighed in an environment of 17 ° C. and 65% relative humidity to about 5 g to 10 g, and then sealed in a polyethylene bag for 24 hours or 48 hours. Store in an environment of 5 ° C. After 24 hours or 48 hours, the surface of the non-cigarette plant composition or the filling for electronic cigarettes may be observed, and the state of precipitation of crystals may be observed in white. The observation of white crystals means that menthol is sublimating and crystallizing from the non-cigarette plant composition or e-cigarette filling. Further, the package is opened in an environment of 17 ° C. and 65% relative humidity for 3 hours in a sealed state, and immediately, the non-tobacco plant composition or the filling for electronic cigarettes is precisely 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 that suppresses the dissipation of other components of the non-tobacco plant composition or the filling for electronic cigarettes, and is a good condition for evaluating the state of dissipation of menthol. Is. In particular, to prevent white crystals from precipitating, consumers will feel uncomfortable when they see the menthol that precipitates when the electronic cigarette cartridge is packaged, placed on the market, transported and stored after manufacturing. It also has the effect of preventing it.

In the present invention, the content of menthol in the non-tobacco plant composition or the filling for electronic cigarettes after weighing about 5 g to 10 g in an environment of 17 ° C. and 65% relative humidity is set to d (0) and set to 5 ° C. The mass of the non-tobacco plant composition or e-cigarette filling after being left for 24 hours is d (24), and the mass of the non-tobacco plant composition or e-cigarette filling after being left at 5 ° C. for 48 hours is d (48).
The menthol reduction rate d is defined below.

d = {(d (24) -d (48)} / d (0)

Here, the reason for subtracting d (48) from d (24) is that the dissipative component other than menthol is taken into consideration, and the dissipative component for 24 hours to 48 hours better reflects the precipitation of the white crystals. Because.

In the present invention, when d is 0.60 or less, precipitation of white crystals can be suppressed. More preferably, it is 0.50 or less, and further preferably 0.30 or less. More preferably, it is 0.20 or less.

Next, an example of using the manufactured filling for electronic cigarettes will be described.

FIG. 1 illustrates a mode of use of an electronic cigarette cartridge. The electronic cigarette cartridge (100) is attached to the electronic cigarette body (200) at the time of use by the user. The electronic cigarette body (200) is provided with an insertion portion (210) for inserting the electronic cigarette cartridge (100).

A heating element (211) is provided in the central portion of the bottom of the insertion portion (210), and the heating element (211) has a pin-shaped or blade-shaped member having a sharp tip to form an aerosol. It is inserted into the substrate (110) and heats the aerosol-forming substrate (110). More specifically, the heating element (211) is placed in the central portion of the aerosol-forming substrate (110) when the electronic cigarette cartridge (100) is inserted into the insertion portion (210) of the electronic cigarette body (200). Will be inserted.

The heating element (211) directly or indirectly generates heat by the electric power supplied from the battery (not shown) provided in the electronic cigarette body (200). The heat of the heating element (211) heats the aerosol-forming base material (110) to generate an aerosol containing an aromatic component. Then, the generated aerosol is transferred to the mouthpiece (140) via the support element (300) and the aerosol transfer member (130) described below, and the user sucks the aerosol from the mouthpiece (140) side to release the aromatic component. It will reach the user's mouth. Hereinafter, for the sake of the description of the present invention, the aerosol-forming base material (110) side of the electronic cigarette cartridge will be referred to as an upstream side (10), and the mouthpiece side will be referred to as a downstream side (20). Further, the upstream side (10) may be referred to as one end side, and the downstream side (20) may be referred to as the other end side.

Note that FIG. 1 shows a case where the heating element (211) has one pin-shaped or blade-shaped member, but as another example of the form, the heating element (211) has a pin-shaped or blade-shaped member. For example, a member having a plurality of shaped members can be exemplified.

FIG. 2 shows an example of the structure of the electronic cigarette cartridge (100). From the side where the heating element (211) is inserted, that is, from the upstream side (10) to the downstream side (20), the aerosol-forming base material (110), the support element (300), the transfer member (130), and the mouth. The structure of the piece (140) will be described.

The support element (300) supports the aerosol-forming substrate (110). The support element (300) is arranged adjacent to the aerosol-forming substrate (110), and the side portion (160) of the support element (300) is located on the peripheral edge of the electronic cigarette cartridge (100). In contact with. The side portion (160) is fixed to the inner surface of the packaging member (150) with, for example, an adhesive.

Further, the support element (300) can be preferably formed by using, for example, silicone, but the support element (300) is not limited to silicone, and other materials having excellent heat resistance may be used.

As shown in FIG. 3, the filler (111) produced as the aerosol-forming base material (110) preferably has a shape such as a rod shape or a strip shape, and is filled with the filler (111) at the time of filling. It is packed so as to follow the longitudinal direction of the shape of. Here, an example in which the inclusion member (151) formed in a cylindrical shape is filled is shown. As the inclusion member (151), a paper such as a cigarette paper formed in a cylindrical shape can be used. Further, the packaging member (150) may also serve as the inclusion member (151). This stabilizes the airflow and makes it easier for the user to inhale the aromatic components from the aerosol-forming substrate (110).

In FIG. 4, the aerosol-forming base material (110), the transfer member (130), the mouthpiece (140) and the supporting element (300) illustrated below are shown in the aerosol-forming base material (110). , The support element (300), the transfer member (130), and the mouthpiece (140) are adjacent to each other in this order, and a winding rod is formed by a packaging member (150) such as tobacco paper. At this time, the electronic cigarette cartridge (100) has a slight adhesive applied to the side portion (160) of the support element.

Next, an example of using the electronic cigarette cartridge of the present invention will be described in detail.

As shown in FIG. 2, the electronic cigarette cartridge (100) has, for example, a rod-shaped or cylindrical appearance.

Inside the electronic cigarette cartridge (100), for example, as shown in FIG. 2, an aerosol-forming base material (110) is provided at one end, and a support element (300) is transferred toward the mouthpiece (140) at the other end. The members (130) are arranged in this order. Then, these are packaged by the packaging member (150).

The aerosol-forming substrate (110) has a filling for electronic cigarettes. The aerosol-forming substrate (110) generates an aerosol containing an aromatic component contained in the plant that is the source of the filling by heating.

As shown in FIG. 3, the filler as the aerosol-forming base material (110) has, for example, a flaky shape in which the long side is about 2 to 20 times as large as the short side, a strip shape, a rod shape, or the like. In the case of, the filling (111) is packed so that the longitudinal direction of the shape is along the longitudinal direction of the cartridge at the time of filling. As a result, the flow of airflow is good and it becomes easy to suck in. It should be noted that FIG. 3 is a view seen from the end of the electronic cigarette cartridge on the side where the aerosol-forming base material (110) is located, and is partially seen through so that the filler (111) inside the cartridge can be seen. However, in each case, the maximum length portion is preferably about 1 to 20 mm. This is because if the maximum length portion is too large, it may be too large to be handled when filling the cartridge. Of course, in addition to this, for example, if the filling is flat and has a substantially constant shape, it can be rolled up and packed, so that it is easy to handle.

As the other aerosol-forming base material, it is also preferable to use a sheet formed by wrinkling, folds, gathering or folding as the shape of the sheet.

The fibrous filling, like the rod-shaped one, is packed so that the length direction of the fiber is along the longitudinal direction of the cartridge to improve the flow of sucked air.

The porous filling is one of the preferable forms because it is porous when packed in a cartridge and therefore improves the air flow when sucked. In order to make it porous, for example, it can be formed by piercing a dried sheet several times with a plurality of needles, but other methods may also be used.

It can be made into a flat plate such as a piece, a square, a rectangle, or a rhombus, or the filling of powder, granules, or pellets can be easily packed by dropping it into the cartridge opening. Further, it is preferable because it is easy to finely adjust the amount to be packed in the cartridge (filling amount), and it is easy to adjust the air flow when sucked by the packing amount. It can be used more preferably by taking measures to prevent it from falling off, such as by covering the cartridge opening with a lid.

The block-shaped filling has good thermal conductivity and easily draws out aromatic components. It is one of the preferred forms. In addition, the size of the block may be increased to facilitate storage. In that case, at the time of filling, the block can be remolded into a small block, a rod shape, a granular shape, or the like.

The support element (300) supports the aerosol-forming substrate (110). The support element (300) was generated from the aerosol-forming substrate (110), arranged adjacent to the aerosol-forming substrate (110), having airflow through holes, notches, etc. in the center or side. Aerosol can be flowed in the direction of the mouthpiece (140).

The mouthpiece (140) is adjacent to the transfer member (130) and is located at the other end of the electronic cigarette cartridge (100). The mouthpiece (140) may include, for example, a cellulose acetate filter as a filter for removing fine particles. The aroma component that has passed through the filter of the mouthpiece (140) is sucked by the user.

Comparing the presence or absence of the transfer member (130), it is easier to suck the generated aroma component because the air permeability is better when the transfer member (130) is not included. On the other hand, it is also preferable to insert a transfer member (130) and add a function capable of cooling the generated aerosol. Instead of adding the transfer member (130), it is also preferable to extend the mouthpiece so that it is adjacent to or in contact with the support element (300). This is because the filter used for the mouthpiece can also have a cooling function, and the number of parts can be reduced. As the transfer member (130), a hollow tubular member can be used, and one in which a crimped polymer sheet is wound in the longitudinal direction of the electronic cigarette cartridge can be used.

FIG. 5 (1) shows a configuration in which the aerosol-forming base material (110) and the supporting element (300) are in contact with each other, and the aerosol-forming base material (110) can be stably supported, which is a preferable form. .. In addition, since the structure is simple, there is a great advantage in manufacturing.

In FIG. 5 (2), a partition wall member (180) is provided between the aerosol-forming base material (110) and the support element (300), and is configured to be in contact with the partition wall member (180). The partition wall member (180) is preferably one that has good air permeability, such as a filter or paper, and that breaks when the heating element (211) is inserted. Providing such a partition member is effective in preventing the aerosol-forming base material (110) from moving in the electronic cigarette cartridge due to the influence of physical distribution such as during transportation.

In FIG. 5 (3), it is also preferable to have a lid (170) on the side where the heating element (211) of the aerosol-forming base material (110) is inserted. In this way, it is effective in preventing the dissipation of the aroma of the aerosol-forming base material (110). Further, there is an effect that the aerosol-forming base material (110) can be prevented from falling out from the electronic cigarette cartridge due to the influence of physical distribution such as during transportation. Examples of the material of the lid (170) include a filter, paper, and sponge. When the heating element is inserted, it is also preferable to make one or more cuts in the lid (170), or to provide a circular or polygonal guide hole at the place where the heating element is inserted. It is a form.

In particular, when granular materials such as powder, granules, flakes, and pellets are used as the aerosol-forming base material (110), it is preferable to provide a partition member (180) or a lid (170). Further, it is more preferable to provide both of them.
Hereinafter, the manufacturing process when black tea or the like is used will be described in detail, but it goes without saying that these are not limited to black tea and the like and can be applied to the tobacco plants and non-tobacco plants described in the present specification.

One specific form preferable for the electronic cigarette cartridge is as follows. The erosol-forming base material (110) has a substantially cylindrical shape in which the filling material is encapsulated with tobacco paper or the like, and the diameter of the bottom surface or the upper surface of the substantially cylindrical shape is 6.5 mm or more and 7.5 mm or less. The height of the cylinder is 11.0 mm or more and 13.0 mm or less. Further, it is preferable that the filling is rod-shaped or strip-shaped, filled along the longitudinal direction of the electronic cigarette cartridge, and the length of the filling is substantially equal to the height of the substantially cylindrical cylinder. That is, it is preferably 11.0 mm or more and 13.0 mm or less.
Further, in the support element (300), it is preferable that the outer diameter is substantially equal to the diameter of the bottom surface or the top surface of the substantially cylindrical surface of the aerosol-forming base material (110). The length thereof is 9.0 mm or more and 11.0 mm or less.
The length of the mouthpiece (140) exceeds 20.0 mm, preferably 21.0 mm or more, and preferably 25.0 mm or less.
Further, the volume filling rate of the aerosol-forming base material is preferably 0.55 or more and 0.65 or less.

FIG. 7 illustrates a further mode of use of the electronic cigarette cartridge. Since there are some differences in the specific configuration from the above-mentioned electronic cigarette cartridge (100), the electronic cigarette cartridge (101) will be described below. The electronic cigarette body used is also different from the above-mentioned electronic cigarette body (200), and will be described below as the electronic cigarette body (201).
It is attached to the electronic cigarette body (201) when used by the user. The electronic cigarette body (201) is provided with an insertion portion (450) for inserting the electronic cigarette cartridge (101). There is an exterior part (410) of the electronic cigarette body (101), and the heating part (440) surrounding the electronic cigarette cartridge heats the aerosol-forming base material (110) of the electronic cigarette cartridge to generate an aerosol and smoke. NS. When smoking from the other end side (20), air flows in from the ventilation hole (431), and the generated aerosol passes through the hollow tubular member (530), the transfer member (130), and the mouthpiece (140) for smoking. Will be done. The control unit (420) has a built-in control device for a battery or a heating unit. The opening / closing lid (430) is opened when cleaning the inside of the main body of the electronic cigarette when smoking is finished.

FIG. 8 shows a further example of the structure of the electronic cigarette cartridge. From one end side (10) to the other end side (20), there are an aerosol-forming base material (110), a hollow tubular member (530), a transfer member (130), a mouthpiece (140), and a packaging member (150). ) Is wrapped. Since the aerosol-forming base material (110) portion is heated by the electronic cigarette body, a hollow tubular member (530) is arranged for heat insulation. The transfer member (130) can also serve as a cooling member.

The preferred shape of the electronic cigarette cartridge of FIG. 8 is an outer diameter of 4 mm or more and 6 mm or less, the aerosol-forming base material (110) is 30 mm or more and 70 mm or less in the longitudinal direction, and the hollow tubular member (530) is It is 20 mm or more and 30 mm or less.

As described above, the obtained electronic cigarette cartridge was evaluated as follows.
Evaluation 1: The prepared electronic cigarette cartridge was filled in a paper box having a long side of 70 mm, a short side of 14 mm, and a height of 45 mm so that the aerosol-forming base material faces the bottom. In this way, the prepared box containing the electronic cigarette cartridge was placed in a polyethylene bag for 48 hours in an environment of 5 ° C. and left to stand.
Then, after taking out, the product left in a normal temperature and humidity environment for one day is evaluated as follows. The surface of the aerosol-forming base material of the electronic cigarette cartridge was observed from one end side, and the number of each cigarette was visually counted using a 5x magnifying glass to see if white crystals of menthol appeared.
Rank A: No white crystals are found Rank B: 1 to 4 white crystals Rank C: 5 or more white crystals Rank C loses menthol due to long-term storage and gives a refreshing feeling. It is likely to be impaired.

Evaluation 2: The outline of the electronic cigarette body to be used will be described. The electronic cigarette body used was Aikos (registered trademark), which is a heated electronic cigarette manufactured by Philip Maurice. The outline of the electric electronic cigarette is as follows. The heating element (211) has a width of 4.5 mm, a length to the tip of 12 mm, and a thickness of 0.4 mm. The inner diameter of the insertion portion (210) is 7 mm, which is substantially equal to the outer diameter of the electronic cigarette cartridge. The heating element (211) generates heat by electric power supplied from a battery (not shown) provided in the electronic cigarette body (200), and reaches about 370 ° C. Then, the built-in control system ends the consumption of one electronic cigarette cartridge after 14 suctions. When the electronic cigarette cartridge of this embodiment is inserted, the electronic cigarette cartridge portion that appears from the downstream side to the outside of the electronic cigarette body is about 20 mm.
The electronic cigarette cartridge manufactured in this example and the comparative example was inserted into the electronic cigarette body, and a smoking test was conducted.
In the smoking test, the prepared electronic cigarette cartridge was filled in a paper box having a long side of 70 mm, a short side of 14 mm and a height of 45 mm so that the aerosol-forming base material faces the bottom. The prepared electronic cigarette cartridge was subjected to a sensory test on the flavor of menthol using a sample left in an environment of 25 ° C. for 2 weeks and a sample immediately after preparation. Sensory tests were performed on the flavor of the sample and menthol immediately after preparation and after leaving. The sensory test was conducted by 5 smokers.
The evaluation criteria are
Rank A: The flavor of menthol does not change in the sample after leaving it as compared with immediately after preparation.
Rank B: The menthol flavor of the sample after leaving is slightly weaker than that immediately after preparation. Rank C: The menthol flavor of the sample after leaving is clearly weaker than that immediately after preparation. The test results are listed in Table 2 below. ..
