[Figure 13] This graph shows the rate of change in width when e-cigarette filling material is dried. [Modes for carrying out the invention]

[0023] Embodiments of the present invention will be described below 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 denoted by the same reference numerals, and redundant explanations are omitted. Also, the dimensional ratios in the drawings are exaggerated for illustrative purposes and may differ from the actual ratios.

[0024] Figure 8 is a flowchart showing an example of the manufacturing process for a non-tobacco plant composition and an e-cigarette filler in an embodiment to which the present invention is applied.

[0025] The manufacturing process for e-cigarette fillers includes a drying and grinding step (A) in which non-tobacco plants that provide the aroma are dried, ground, and weighed. This step can be omitted if the raw materials can be used as is. In addition, other materials used in the manufacturing of e-cigarette fillers include a preparation step (B) in which pre-treatment and weighing are performed as needed.

[0026] After the drying and grinding process (A) and the preparation process (B), the materials proceed to the mixing process (M), where they are mixed under predetermined conditions to form a non-tobacco plant composition.

[0027] The non-tobacco plant composition can be formed into a desired shape through a filler molding process (F). The non-tobacco plant composition, formed into the desired shape, is then used as a filler for e-cigarettes in an e-cigarette cartridge manufacturing process (G) to become an e-cigarette cartridge.

[0028] Each step will be explained in order. Although the invention has been explained by dividing it into the above steps, it also includes performing two or more steps simultaneously. Details of the non-tobacco plants used as raw materials will be described later.

[0029] First, the drying and grinding process (A) processes the parts of the non-tobacco plant used as raw material (e.g., leaves, seeds, dried fruits, stems, bark, roots, etc.) into a desired grind to form a non-tobacco plant composition. At this time, it is also preferable to adjust the moisture content so that it is suitable 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 moisture content while avoiding the dissipation of necessary flavor components. If it is 65°C or higher, This makes it easier to reach the desired moisture content, and keeping the temperature below 75°C further prevents the dissipation of necessary flavor components.

[0030] Furthermore, it is preferable that the moisture content after drying and grinding be 5% by mass or less. This facilitates slurry formation in subsequent processes. It is even preferable that it be 3% by mass or less. In addition, if the moisture content is preferably 0.1% by mass or more, it is possible to maintain a state in which it mixes well with water, etc. Furthermore, the drying and grinding process (A) can be equipped with a sieving process to separate the dried and ground material, and it can be introduced into the mixing process (M) with the desired particle size.

[0031] In preparation step (B), the materials necessary for creating the refill for e-cigarettes can be prepared.

[0032] Microcrystalline cellulose is obtained, for example, by partially depolymerizing α-cellulose obtained from fibrous plant pulp with an acid, in which the soluble portion is removed from cellulose and the insoluble portion is crystallized as appropriate.

[0033] After various studies, the following was found regarding e-cigarette fillers containing non-tobacco plants, aerosol formers, and microcrystalline cellulose: When the e-cigarette filler is placed under dry conditions, even if the filler composed of non-tobacco plants and aerosol formers loses water, the microcrystalline cellulose maintains the structure of the filler and suppresses structural changes such as volume shrinkage. This effect is obtained by using microcrystalline cellulose.

[0034] In this invention, as one example, microcrystalline cellulose is weighed in the preparation step (B) and added to the mixing step (M). The microcrystalline cellulose may be added as a powder or dispersed in a solvent such as water as a suspension. In this case, a high-speed stirrer or a high-pressure homogenizer can be used for dispersion in the solvent.

[0035] The amount of microcrystalline cellulose added should ideally be between 1% and 15% in the e-cigarette filling. Preferably, it should be between 3% and 12%, and more preferably between 5% and 10%.

[0036] The addition of microcrystalline cellulose improves moldability, enhances workability during processes such as kneading with a roll mill, and is particularly effective in suppressing shrinkage and volume changes in e-cigarette fillers, thus contributing to quality control and homogenization of the user experience of e-cigarette cartridges.

[0037] The average particle size of the microcrystalline cellulose used in the present invention is preferably 30 μm or more and 200 μm or less, more preferably 50 μm or more and 150 μm or less, and more preferably 70 μm or more and 120 μm or less.

[0038] When the average particle size of microcrystalline cellulose is 30 μm or more, it has an excellent effect in suppressing the shrinkage of e-cigarette fillers, and when it is 150 μm or less, in addition to the effect of suppressing shrinkage, it can also provide good moldability.

[0039] The average particle size of microcrystalline cellulose is determined by sieving. The above average particle size can be obtained by the method described in JIS K 0069:1992. The average particle size is defined as the diameter corresponding to 50% of the mass obtained by summing the masses from the largest mesh opening of multiple sieves, for example. Furthermore, preferably, the residue on the sieve with a mesh size of 250 μm is 8% by mass or less, and the residue on the sieve with a mesh size of 75 μm is 45% by mass or more.

[0040] If the residue on a sieve with a mesh size of 250 μm is 8% by mass or less, the sieved microcrystalline cellulose has the effect of suppressing the shrinkage of the e-cigarette filler. If the residue on a sieve with a mesh size of 75 μm is 45% by mass or more, the moldability of the e-cigarette filler can be improved.

[0041] The mass-average molecular weight (Mw) of microcrystalline cellulose is preferably between 10,000 and 200,000. A Mw of 10,000 or more provides excellent suppression of shrinkage in e-cigarette fillers, while a Mw of 100,000 or less provides good moldability in addition to the aforementioned shrinkage suppression effect. Particularly preferred is a Mw of 20,000 to 60,000. The molecular weight of cellulose can be measured by gel permeation chromatography (GPC). For example, a measurement method as described in Japanese Patent Publication No. 6-109715 can be employed, with polyethylene glycol or the like being used as a standard material as appropriate.

[0042] Next, we will explain the mixing process (M).

[0043] The non-tobacco plants used as raw materials undergo drying and grinding processes (A) as needed, are weighed, and then proceed to the mixing process (M).

[0044] The non-tobacco plants used as raw materials will be described below. In this embodiment, there are no particular restrictions on the non-tobacco plants that can be used, as long as they are plants other than tobacco. Various parts of the plant can be used, such as roots (including bulbs, tubers, and bulbs), stems, tubers, bark (including stem bark and tree bark), leaves, flowers (including petals, pistils, and stamens), and tree trunks and branches.

[0045] Examples of bulbs include onions, spider lilies, tulips, hyacinths, garlic, shallots, and lilies. Examples of corms include crocuses, gladiolus, freesias, irises, taro, and konjac.

Examples of stems include konjac, asparagus, bamboo shoots, Japanese angelica tree, radishes, and yacon.

[0046] The above-mentioned tubers or the plants listed below contain carbohydrates and are preferably used as at least a part of the filling material 111. For example, starches include corn starch (corn), potato starch (potato), sweet potato starch (sweet potato), tapioca starch (tapioca), etc., and have been used as thickeners, stabilizers, etc. These starches can be improved by crosslinking to enhance acid resistance, heat resistance, and shear resistance, etc., by esterification and etherification to improve storage stability and accelerate gelatinization, etc., and by oxidation to improve transparency, film properties, and storage stability, etc.

[0047] From plant seeds, tamarind seed gum, guar gum, and locust bean gum can be obtained; from tree sap, gum arabic and karaya gum; from fruits, pectin; and from other plants, konjac mannan (mainly composed of cellulose and agarose) and soybean polysaccharides can be obtained. Furthermore, these can be modified and used, such as cationized guar gum.

[0060] Furthermore, extracts of non-tobacco plants, as exemplified above, can also be used. Examples of extract forms include liquid, syrup, powder, granules, and solution.

[0061] Of the examples of non-tobacco plants described above, those that do not require drying or grinding can be added directly to the mixing process (M).

[0062] Other materials that can be used as fillings for e-cigarettes include the following:

[0063] Suitable aerosol formers include glycerin, propylene glycol, sorbitol, triethylene glycol, lactic acid, diacetin (glycerin diacetate), triacetin (glycerin triacetate), triethylene glycol diacetate, triethyl citrate, isopropyl myristate, methyl stearate, dimethyl dodecanedione, and dimethyl tetradecanedione, but glycerin and propylene glycol are particularly preferred. These are used in amounts of 1% to 80% by mass relative to the e-cigarette filler, and are particularly preferably 10% to 40% by mass.

[0064] Furthermore, flavoring additives are preferably used as needed to enhance the flavor. Examples of flavoring additives include mint, cocoa, coffee, and tea extracts.

[0065] Furthermore, food preservatives may be added as needed, such as sorbic acid, potassium sorbate, benzoic acid, or sodium benzoate.

[0066] Other materials used besides those mentioned above include binders or thickeners such as gums like guar gum, xanthan gum, acacia gum, and locust bean gum; cellulose binders such as hydroxypropyl cellulose, carboxymethyl cellulose, hydroxyethyl cellulose, methyl cellulose, and ethyl cellulose; polysaccharides such as starch, organic acids such as alginic acid, sodium alginate, sodium carboxymethylcellulose, caranagin, agar, and pectin (conjugated base salts of organic acids); and combinations thereof.

[0067] The aerosol formers, flavor additives, preservatives, binders, or thickeners exemplified above are prepared in the preparation step (B) shown in Figure 8, and then proceed to the mixing step (M).

[0068] In the mixing process (M), a conventional mixer can be used. For example, a configuration in which the materials in the mixing tank are mixed while applying shear force with stirring blades is preferably used.

[0069] Next is the filling molding process (F), which can be exemplified by a method of forming a rod shape by passing the non-tobacco plant composition through an orifice under pressure, a method of forming it into a thin sheet, or a method of drying and crushing the non-tobacco plant composition to form granules.

[0070] This invention will describe in detail a method of forming a thin sheet and then cutting it. A three-roll mill was prepared to create the thin sheet. Using a three-roll mill is preferable because it allows for kneading and dispersion through compression by pressing the material between the narrow rolls and shearing due to the difference in roll speeds, while simultaneously forming a sheet of the desired thickness with a doctor blade. Alternatively, it is also preferable to use a press roller or a press machine.

[0071] Furthermore, in the filling molding process (F), non-tobacco plants, aerosol formers, binders or thickeners, flavor additives, preservatives, etc. may be added as needed, or water may be added.

[0072] In this invention, although the term "water" is used, it is preferable to use water that has been sterilized or from which microorganisms have been removed for use in manufacturing, and it is preferable to use pure water obtained by reverse osmosis or ion exchange.

[0073] In the filling molding process (F), the thickness of the resulting sheet 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 resulting sheet is cut into the desired shape, and examples of cutting methods include cutters and rotary cutters with rotating blades.

[0074] As a specific example of the filler molding process (F), we will take the example of cutting a 0.3 mm thick sheet into a desired shape. For example, cut it into a rectangle with a length of 150 mm and a width of 240 mm. This sheet is fed into a rotary cutter and cut into a shape of 1.5 mm in length and 240 mm in width to obtain sheet cut pieces. 50 of these sheet cut pieces are wrapped in cigarette paper to create a roll with an outer diameter of approximately 6.9 mm. The roll is cut with a cutter to a length of 12.0 mm to obtain an aerosol-forming substrate (110). In this case, the mass of the filler is 0.29 g. If the ratio of the volume of the filler to the volume of the aerosol-forming substrate (110) is called the volume filling rate, then in the above case the volume filling rate is 0.60. Then, the density of the filler calculated from the volume filling rate and the mass of the filler is 1.07 g / cm3.

[0075] In the above-described filling molding process (F), multiple rod-shaped or strip-shaped fillings are arranged along the longitudinal direction of the electronic cigarette cartridge. Furthermore, these multiple rod-shaped or strip-shaped fillings are enclosed by an enclosing member (151) such as tobacco paper along the axis of the roll height, forming an aerosol-forming substrate (110).

[0076] The electronic cigarette cartridge manufacturing process (G) is described below. The aerosol-forming substrate (110) obtained in this way, the support element (300) which will be described in detail below, and the mouthpiece (140) are wrapped in a packaging member (150), or the packaging member (150) is made into a cylindrical shape in advance, and the mouthpiece (140), support element (300), and filling material (111) are inserted into it. Accordingly, an example of a preferred configuration of the present invention is an electronic cigarette cartridge comprising an aerosol-forming substrate (110), a support element (300), and a mouthpiece (140) arranged from the upstream side (10) to the downstream side (20).

[0077] When using the electronic cigarette body of the present invention with a heating element inserted, a preferred form is a filler molded to have 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.

[0078] In this invention, the reason for including microcrystalline cellulose in the electronic cigarette filler is that the presence of crystalline cellulose makes it easier to blend with the filler composition, increasing mechanical strength and structural stability, reducing changes in length, width, and thickness over time, and consequently reducing volume changes.

[0079] This is expected to improve the moldability of the filler material and enhance workability during processes such as kneading with a roll mill. In particular, it is effective in suppressing the rate of change in length, width, thickness, and volume due to shrinkage of e-cigarette fillers.

[0080] By adding microcrystalline cellulose of a predetermined particle size to the filler material in this invention, it is possible to suppress the rate of change in length, width, thickness, and volume even when the filler is made into the shape described above, and to suppress the problem of the e-cigarette filler falling out of the e-cigarette cartridge during transportation. Furthermore, by suppressing the aforementioned changes over time after manufacturing, it is possible to homogenize the user experience regardless of the time elapsed since manufacturing, which is also effective in terms of quality maintenance and management.

[0081] The properties of the e-cigarette filler prepared as described above can be verified as follows: The effect of microcrystalline cellulose can be evaluated by observing the changes in length, thickness, and volume of the non-tobacco plant composition or e-cigarette filler under predetermined conditions.

[0082] The prepared non-tobacco plant composition or e-cigarette filler can be dried using a halogen moisture meter, and the length, width, thickness, and volume of the filler before and after drying can be measured and the rate of change can be evaluated.

[0083] In this invention, the length, width, thickness, and volume of the non-tobacco plant composition sheet or e-cigarette filler before drying are measured when the moisture content of the non-tobacco plant composition sheet or e-cigarette filler is 15% by mass or more and 20% by mass. To adjust the moisture content, for example, it can be adjusted at 28°C to 30°C and a relative humidity of about 40%. The moisture content was measured using an electronic halogen moisture meter, model number DHS-50-5 (manufactured by Bangxi Instrument Technology Co. Ltd.). In automatic drying mode, the drying temperature was set to 105°C, and the moisture content (by mass) was determined from the water loss rate at the end of the automatic measurement. In automatic measurement mode, the water loss rate is calculated by subtracting the sample mass at the end of measurement from the sample weight at the beginning of measurement and dividing by the sample mass at the beginning of measurement. The change in mass is taken as the moisture content.

[0084] The percentage changes in length, width, thickness, and volume of non-tobacco plant compositions or e-cigarette fillers are calculated by subtracting the values ​​of length, width, thickness, and volume after drying for a predetermined time from the values ​​of length, width, thickness, and volume before drying, and then dividing by the values ​​of length, width, thickness, and volume before drying.

[0085] Specifically, L0 is the length of the non-tobacco plant composition or e-cigarette filler before drying. L10 is the length of the non-tobacco plant composition or e-cigarette filler after a drying time of 10 minutes.

Wb(%) = (W0 - W15) / W0 × 100

[0087] The thickness of the non-tobacco plant composition or e-cigarette filler before drying is T0. The thickness of the non-tobacco plant composition or e-cigarette filler after a drying time of 10 minutes is T10. The percentage change in thickness Ta (%) of the non-tobacco plant composition or e-cigarette filler after a drying time of 10 minutes is defined as follows. Ta(%) = (T0 - T10) / T0 × 100 Furthermore, when the thickness of the non-tobacco plant composition or e-cigarette filler after a drying time of 15 minutes is defined as T15, the percentage change in thickness Tb (%) of the non-tobacco plant composition or e-cigarette filler after a drying time of 15 minutes is defined as follows. Tb(%) = (T0 - T15) / T0 × 100

[0088] V0 is the volume of the non-tobacco plant composition or e-cigarette filler before drying. The volume of the non-tobacco plant composition or e-cigarette filler after a drying time of 10 minutes is V10. The volume change rate Va(%) of the non-tobacco plant composition or e-cigarette filler after a drying time of 10 minutes is defined as follows: Va(%) = (V0 - V10) / V0 × 100 Furthermore, if the volume of the non-tobacco plant composition or e-cigarette filler after a drying time of 15 minutes is V15, the volume change rate Vb(%) of the non-tobacco plant composition or e-cigarette filler after a drying time of 15 minutes is defined as follows. Vb(%) = (V0 - V15) / V0 × 100

More preferably, it is 93.0% or more. Even more preferably, it is 93.5% or more.

[0104] Next, we will explain examples of how the manufactured e-cigarette refills can be used.

[0105] Figure 1 illustrates the usage configuration of an e-cigarette cartridge. The e-cigarette cartridge (100) is attached to the e-cigarette device (200) when used by the user. The e-cigarette device (200) is provided with an insertion part (210) for inserting the e-cigarette cartridge (100).

[0106] A heating element (211) is provided in the center of the bottom of the insertion part (210). The heating element (211) has a pin-shaped or blade-shaped member with a pointed tip and is inserted into the aerosol-forming substrate (110) to heat the aerosol-forming substrate (110). More specifically, the heating element (211) is inserted into the center of the aerosol-forming substrate (110) when the electronic cigarette cartridge (100) is inserted into the insertion part (210) of the electronic cigarette body (200).

[0107] The heating element (211) generates heat directly or indirectly from power supplied from a battery (not shown) located inside the e-cigarette body (200). The heat from this heating element (211) warms the aerosol-forming substrate (110), generating an aerosol containing aromatic components. The generated aerosol is then transferred to the mouthpiece (140) via the support element (300) and aerosol transfer member (130), which will be described below. When the user inhales from the mouthpiece (140), the aromatic components reach the user's mouth. Hereinafter, for the purpose of explaining the present invention, the aerosol-forming substrate (110) side of the e-cigarette cartridge will be referred to as the upstream side (10), and the mouthpiece side as the downstream side (20). The upstream side (10) may also be referred to as one end, and the downstream side (20) as the other end.

[0108] Although Figure 1 illustrates a case where the heating element (211) has one pin-shaped or blade-shaped member, another example of a different configuration is one in which the heating element (211) has multiple pin-shaped or blade-shaped members.

[0109] Figure 2 shows an example of the structure of an electronic cigarette cartridge (100). Starting from the side into which the heating element (211) is inserted, that is, from the upstream side (10) to the downstream side (20), the configuration consists of an aerosol forming substrate (110), a support element (300), a transport member (130), and a mouthpiece (140).

[0110] The support element (300) supports the aerosol-forming substrate (110). The support element (300) is positioned adjacent to the aerosol-forming substrate (110), and the side portion (160) of the support element (300) is in contact with the packaging member (150) located on the periphery of the e-cigarette cartridge (100). The side portion (160) is fixed to the inner surface of the packaging member (150), for example, by adhesive.

[0111] Furthermore, the support element (300) may preferably be formed using, for example, silicone, but is not limited to silicone, and other materials with excellent heat resistance may be used.

[0112] As shown in Figure 3, the filler (111) manufactured as the aerosol-forming substrate (110) is preferably shaped like a rod or a strip, and is packed along the longitudinal direction of the filler (111) during filling. Here, an example of filling into a cylindrical encapsulating member (151) is shown. As the encapsulating member (151), paper such as cigarette paper formed into a cylindrical shape can be used. Alternatively, the packaging member (150) may also serve as the encapsulating member (151). This stabilizes the airflow and makes it easier for the user to inhale the aromatic components from the aerosol-forming substrate (110).

[0113] Figure 4 shows how the aerosol-forming substrate (110), transport member (130), mouthpiece (140), and support element (300) described below are arranged adjacent to each other in the order of aerosol-forming substrate (110), support element (300), transport member (130), and mouthpiece (140), and a winding rod is formed with packaging material (150) such as cigarette paper. At this time, a small amount of adhesive is applied to the side (160) of the support element, resulting in an electronic cigarette cartridge (100).

[0114] Next, we will describe in detail examples of how to use the electronic cigarette cartridge of the present invention.

[0115] The electronic cigarette cartridge (100) has an appearance such as a rod or cylindrical shape, as shown in Figure 2.

[0116] The inside of the electronic cigarette cartridge (100) is arranged in the following order, for example, as shown in Figure 2: an aerosol-forming substrate (110) is provided at one end, and a support element (300) and a transport member (130) are arranged toward the mouthpiece (140) at the other end. These are then packaged by a packaging member (150).

[0117] The aerosol-forming substrate (110) has a filling material for electronic cigarettes. The aerosol-forming substrate (110) generates an aerosol containing aromatic components from the plant that formed the filling material when heated.

[0118] As shown in Figure 3, when the filler material used as the aerosol-forming substrate (110) is in the form of a piece, strip, or rod, where the long side is approximately 2 to 20 times the short side, the filler material (111) should be packed so that its long side is aligned with the long side of the cartridge. This improves airflow and makes inhalation easier. Figure 3 is a view from the end of the e-cigarette cartridge where the aerosol-forming substrate (110) is located, and is partially a perspective view so that the filler material (111) inside the cartridge is visible. However, it is preferable that the maximum length of the filler material be approximately 1 to 20 mm. This is because if the maximum length is too large, it may become too large and difficult to handle when filling the cartridge. Of course, other types of filler material are also acceptable; for example, a flat plate with a nearly uniform shape can be rolled up and packed, making it easier to handle.

[0119] As for other aerosol-forming substrates, it is also preferable to use those formed in the shape of a sheet by creasing, pleating, gathering, or folding.

[0120] Similar to rod-shaped materials, fibrous fillers are packed so that the length of the fibers aligns with the longitudinal direction of the cartridge, thereby improving the airflow of the inhaled air.

[0121] Porous fillers are a preferred form because their porous nature improves airflow when suctioned after being packed into a cartridge. Porous properties can be created, for example, by repeatedly puncturing a dry sheet with multiple needles, but other methods may also be used.

[0122] The filling material can be in the form of a flat plate such as a flake, square, rectangle, or rhombus, or it can be powder, granules, or pellets, and can be easily packed into the cartridge opening by dropping them in. Furthermore, it is preferable because the amount packed into the cartridge (filling amount) can be easily adjusted, and the airflow when suctioned can be easily adjusted by changing the amount packed. It can be used even more favorably by taking measures to prevent the material from falling out, such as by covering the cartridge opening.

[0123] Block-shaped fillers have good thermal conductivity and easily extract aromatic components. This is one of the preferred forms. The size of the blocks can also be increased for easier storage. In that case, the blocks can be reshaped into smaller blocks, rods, granules, or other forms during filling.

[0124] The support element (300) supports the aerosol-forming substrate (110). The support element (300) is positioned adjacent to the aerosol-forming substrate (110) and has airflow holes or notches in its center or side so that the aerosol generated from the aerosol-forming substrate (110) can be directed toward the mouthpiece (140).

[0125] The mouthpiece (140) is adjacent to the transport member (130) and positioned at the other end of the e-cigarette cartridge (100). The mouthpiece (140) may include a filter for removing particulate matter, such as a cellulose acetate filter. The fragrance components that pass through the filter of the mouthpiece (140) are inhaled by the user.

[0126] Comparing the presence and absence of the transport member (130), the absence of the transport member (130) results in better ventilation and easier inhalation of the generated aromatic components. On the other hand, it is also preferable to include the transport member (130) to add a function that can cool the generated aerosol. Alternatively, instead of adding the transport 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 in the mouthpiece can also serve as a cooling element, and the number of parts can be reduced.

[0127] As the transfer member (130), a hollow tubular member can be used, such as one in which a crimped polymer sheet is wound in the longitudinal direction of the electronic cigarette cartridge.

[0128] Figure 5(1) shows a configuration in which the aerosol-forming substrate (110) and the support element (300) are in contact. This is a preferred configuration because it allows for stable support of the aerosol-forming substrate (110). Furthermore, its simple structure offers significant manufacturing advantages.

[0129] Figure 5(2) shows a configuration in which a partition member (180) is provided between the aerosol-forming substrate (110) and the support element (300), and the two are in contact via the partition member (180). The partition member (180) can be made of, for example, a breathable filter or paper, and it is preferable that it is designed to break when the heating element (211) is inserted. Providing such a partition member is effective in preventing the aerosol-forming substrate (110) from moving around in the e-cigarette cartridge due to the effects of logistics such as transportation.

[0130] Figure 5(3) also shows a configuration in which a lid (170) is placed on the side of the aerosol-forming substrate (110) into which the heating element (211) is inserted. This is effective in preventing the dissipation of the aroma of the aerosol-forming substrate (110). Furthermore, it has the effect of preventing the aerosol-forming substrate (110) from falling out of the e-cigarette cartridge due to the effects of logistics such as transportation. The material of the lid (170) can be a filter, paper, or sponge. When a heating element is inserted, it is also preferable to make one or more slits in the lid (170), or to provide a circular or polygonal guide hole in the place where the heating element is inserted.

[0131] In particular, when granular materials such as powder, granules, flakes, or pellets are used as the aerosol-forming substrate (110), it is preferable to provide a partition member (180) or a lid (170). Furthermore, it is even preferable to provide both. The manufacturing process using black tea, etc., will be described in detail below, but it goes without saying that these are not limited to black tea, etc., and can be applied to non-tobacco plants as described herein.

[0132] One preferred specific form of an electronic cigarette cartridge is as follows: The aerosol-forming substrate (110) is a substantially cylindrical shape in which the filler is enclosed in tobacco paper or the like, with the diameter of the bottom or top surface of the substantially cylindrical being 6.5 mm or more and 7.5 mm or less, and the height of the substantially cylindrical being 11.0 mm or more and 13.0 mm or less. Furthermore, it is preferable that the filler is in the shape of a rod or strip and is filled along the longitudinal direction of the electronic cigarette cartridge, and that the length of the filler is approximately equal to the height of the substantially cylindrical. That is, it is preferable that it is 11.0 mm or more and 13.0 mm or less. Furthermore, in the case of the support element (300), the outer diameter is preferably approximately equal to the diameter of the bottom or top surface of the roughly cylindrical aerosol-forming substrate (110). Also, its length is 9.0 mm or more and 11.0 mm or less. Furthermore, the mouthpiece (140) has a length exceeding 20.0 mm, preferably 21.0 mm or more, and preferably 25.0 mm or less. Furthermore, it is preferable that the volume filling rate of the aerosol-forming substrate is 0.55 or more and 0.65 or less.

[0133] Figure 6 illustrates further uses of the e-cigarette cartridge. Since it differs in specific configuration from the aforementioned e-cigarette cartridge (100), it will be referred to as e-cigarette cartridge (101) and described below. The e-cigarette device used also differs from the aforementioned e-cigarette device (200), so it will be referred to as e-cigarette device (201) and described below. The electronic cigarette cartridge (101) is attached to the electronic cigarette body (201) when used by the user. The electronic cigarette body (201) is provided with an insertion section (450) for inserting the electronic cigarette cartridge (101). The electronic cigarette body (101) has an outer casing (410), and a heating section (440) surrounding the electronic cigarette cartridge heats the aerosol-forming substrate (110) of the electronic cigarette cartridge, generating an aerosol for smoking. When smoking from the other end (20), air flows in from the vent hole (431), and the generated aerosol passes through the hollow cylindrical member (530), the transport member (130), and the mouthpiece (140) for smoking. The control unit (420) contains a battery or a control device for the heating section, etc. The opening / closing cover (430) is opened when smoking is finished and the inside of the electronic cigarette body is cleaned.

[0134] Figure 7 shows another example of the structure of an e-cigarette cartridge. From one end (10) to the other end (20), there is an aerosol-forming substrate (110), a hollow cylindrical member (530), a transport member (130), and a mouthpiece (140), all encased in a packaging member (150). The aerosol-forming substrate (110) is heated by the e-cigarette body, so the hollow cylindrical member (530) is placed there for insulation. The transport member (130) can also serve as a cooling member.

[0135] The preferred shape for the electronic cigarette cartridge shown in Figure 7 is an outer diameter of 4 mm to 6 mm, with the aerosol-forming substrate (110) being 30 mm to 70 mm in length, and the hollow cylindrical member (530) being 20 mm to 30 mm. The transport member (130) is 5 mm to 15 mm, and the mouthpiece (140) is 10 mm to 25 mm.

[0136] The present invention will be described below with reference to manufacturing examples and embodiments.

[0137] (Manufacturing Example 1) Tea leaves were dried at 70°C, ground, and passed through an 80-mesh sieve. The moisture content was 2% by mass.

[0138] 100 parts by mass of dried and ground black tea leaves Glycerin 30 parts by mass Propylene glycol 30 parts by mass Menthol 5 parts by mass Microcrystalline cellulose 15 parts by mass Polyvinylpolypyrrolidone 10 parts by mass 4 parts by mass of sodium carboxymethylcellulose Xylitol 1.5 parts by mass Glucomannan 1 part by mass The mixture was placed in a mixer and mixed for 15 minutes to obtain a non-tobacco plant composition.

[0139] For example 1, the microcrystalline cellulose used had an average particle size of 90 μm and a mass-average molecular weight (Mw) of 36,000. The residue on a sieve with a mesh size of 75 μm was 52% by mass, and the residue on a sieve with a mesh size of 250 μm was 1% by mass.

[0140] The obtained non-tobacco plant composition was introduced into the filler molding process (F). The non-tobacco plant composition was kneaded and dispersed in a three-roll mill to form a sheet of the desired thickness. In this example, the process of introducing the non-tobacco plant composition into a three-roll mill, adding 20 parts by mass of pure water while observing the state of the sheet, and pressing a doctor blade against the rolls to collect the sheet-like material was repeated eight times to obtain a non-tobacco plant composition sheet.

[0141] The non-tobacco plant composition sheet obtained in this way had a thickness of 0.3 mm. The non-tobacco composition sheet was cut into a rectangle measuring 150 mm in length and 240 mm in width. The non-tobacco plant composition sheet was further processed into a shape with a width of 15 mm, a length of 50 mm, and a thickness of 0.3 mm. The mass of the processed composition sheet was approximately 0.30 g.

[0142] (Manufacturing example 2) A non-tobacco plant composition sheet was obtained in the same manner as in Production Example 1. Subsequently, the material was fed into a rotary cutter and processed into a filler with a width of 1.5 mm, a length of 240 mm, and a thickness of 0.1 mm. Fifty of these fillers were bundled together, aligned longitudinally, wrapped in paper with a basis weight of 34 g / m2, and glued to form a cylindrical shape. The inner diameter of the cylinder was 6.9 mm. The cylindrical processed material was cut to a length of 12.0 mm to form an aerosol-forming substrate (110). The mass of the aerosol-forming substrate was 0.29 g, and the volume filling ratio of the filler to the volume of the aerosol-forming substrate was 0.60.

Subsequently, the material was fed into a rotary cutter and processed into a filler with a width of 1.5 mm, a length of 240 mm, and a thickness of 0.5 mm. Fifty of these fillers were bundled together, aligned longitudinally, wrapped in paper with a basis weight of 34 g / m2, and glued to form a cylindrical shape. The inner diameter of the cylinder was 6.9 mm. The cylindrical processed material was cut to a length of 12.0 mm to form an aerosol-forming substrate (110). The mass of the aerosol-forming substrate was 0.29 g, and the volume filling ratio of the filler to the volume of the aerosol-forming substrate was 0.60.

[0145] (Manufacturing example 5) For the non-tobacco plant composition in Production Example 1, a tobacco plant composition sheet was prepared in the same manner as in Production Example 1, but without using microcrystalline cellulose.

[0146] (Manufacturing example 6) A non-tobacco plant composition sheet was obtained in the same manner as in Production Example 5. Subsequently, the material was fed into a rotary cutter and processed into a filler with a width of 1.5 mm, a length of 240 mm, and a thickness of 0.1 mm. Fifty of these fillers were bundled together, aligned longitudinally, wrapped in paper with a basis weight of 34 g / m2, and glued to form a cylindrical shape. The inner diameter of the cylinder was 6.9 mm. The cylindrical processed material was cut to a length of 12.0 mm to form an aerosol-forming substrate (110). The mass of the aerosol-forming substrate was 0.29 g, and the volume filling ratio of the filler to the volume of the aerosol-forming substrate was 0.60.

[0147] (Manufacturing example 7) A non-tobacco plant composition sheet was obtained in the same manner as in Production Example 5. Subsequently, the material was fed into a rotary cutter and processed into a filler with a width of 1.5 mm, a length of 240 mm, and a thickness of 0.3 mm. Fifty of these fillers were bundled together, aligned longitudinally, wrapped in paper with a basis weight of 34 g / m2, and glued to form a cylindrical shape. The inner diameter of the cylinder was 6.9 mm. The cylindrical processed material was cut to a length of 12.0 mm to form an aerosol-forming substrate (110). The mass of the aerosol-forming substrate was 0.29 g, and the volume filling ratio of the filler to the volume of the aerosol-forming substrate was 0.60.

[0148] (Manufacturing example 8) A non-tobacco plant composition sheet was obtained in the same manner as in Production Example 5. Subsequently, the material was fed into a rotary cutter and processed into a filler with a width of 1.5 mm, a length of 240 mm, and a thickness of 0.5 mm. Fifty of these fillers were bundled together, aligned longitudinally, wrapped in paper with a basis weight of 34 g / m2, and glued to form a cylindrical shape. The inner diameter of the cylinder was 6.9 mm. The cylindrical processed material was cut to a length of 12.0 mm to form an aerosol-forming substrate (110). The mass of the aerosol-forming substrate was 0.29 g, and the volume filling ratio of the filler to the volume of the aerosol-forming substrate was 0.60.

[0149] (Manufacturing example 9) For the non-tobacco plant composition in Production Example 1, a tobacco plant composition sheet was prepared in the same manner as in Production Example 1, using methylcellulose instead of microcrystalline cellulose. Subsequently, the material was fed into a rotary cutter and processed into a filler with a width of 1.5 mm, a length of 240 mm, and a thickness of 0.3 mm. Fifty of these fillers were bundled together, aligned longitudinally, wrapped in paper with a basis weight of 34 g / m2, and glued to form a cylindrical shape. The inner diameter of the cylinder was 6.9 mm. The cylindrical processed material was cut to a length of 12.0 mm to form an aerosol-forming substrate (110). The mass of the aerosol-forming substrate was 0.29 g, and the volume filling ratio of the filler to the volume of the aerosol-forming substrate was 0.60.

[0150] (Manufacturing example 10) For the non-tobacco plant composition in Production Example 1, 4 parts by mass of microcrystalline cellulose were used, and a non-tobacco plant composition sheet was prepared in the same manner as in Production Example 1 in all other respects. Subsequently, the material was fed into a rotary cutter and processed into a filler with a width of 1.5 mm, a length of 240 mm, and a thickness of 0.3 mm. Fifty of these fillers were bundled together, aligned longitudinally, wrapped in paper with a basis weight of 34 g / m2, and glued to form a cylindrical shape. The inner diameter of the cylinder was 6.9 mm. The cylindrical processed material was cut to a length of 12.0 mm to form an aerosol-forming substrate (110). The mass of the aerosol-forming substrate was 0.29 g, and the volume filling ratio of the filler to the volume of the aerosol-forming substrate was 0.60.

[0151] (Example 1) In Manufacturing Example 2, an aerosol-forming substrate, a cylindrical hollow tube support element (300), and a filter (140) to serve as a mouthpiece were prepared. The support element (300) had a bottom and top diameter, i.e., an outer diameter of 6.9 mm, and a 4 mm through-hole in the hollow portion. A 23 mm long filter (140) was used to serve as the mouthpiece. As a packaging material, paper with a basis weight of 38 g / m2 was used, wound two and a half times to achieve an inner diameter of 6.9 mm, and then glued. Thus, creating a paper tube by winding paper with a basis weight of 32 g / m2 to 45 g / m2 two and a half times and using it as a packaging material makes it suitable as an e-cigarette cartridge for use in an e-cigarette body into which a heating element is inserted.

[0152] Adhesive was applied to the inside of the paper tube, a filter was inserted from the other end (20) to form a mouthpiece (140), a support element (300) was inserted from the one end (10), and then an aerosol-forming substrate was inserted. Furthermore, paper with a basis weight of 40 g / m2 was wrapped around the mouthpiece portion so as to overlap the mouthpiece (140) almost completely. This is how I created the e-cigarette cartridge.

[0153] (Example 2) In Example 1, an e-cigarette cartridge was prepared in the same manner as in Example 1, using the aerosol-forming substrate prepared in Production Example 3 instead of the aerosol-forming substrate prepared in Production Example 2.

[0154] (Example 3) In Example 1, an e-cigarette cartridge was prepared in the same manner as in Example 1, using the aerosol-forming substrate prepared in Production Example 4 instead of the aerosol-forming substrate prepared in Production Example 2.

[0155] (Example 4) In Example 1, an e-cigarette cartridge was prepared in the same manner as in Example 1, using the aerosol-forming substrate prepared in Production Example 10 instead of the aerosol-forming substrate prepared in Production Example 2.

[0156] (Comparative Example 1) In Example 1, instead of using the aerosol-forming substrate prepared in Manufacturing Example 2, an e-cigarette cartridge was prepared using the aerosol-forming substrate prepared in Manufacturing Example 6, in the same manner as in Example 1.

[0157] (Comparative Example 2) In Comparative Example 1, an e-cigarette cartridge was prepared in the same manner as in Comparative Example 2, using the aerosol-forming substrate prepared in Production Example 7 instead of the aerosol-forming substrate prepared in Production Example 6.

[0158] (Comparative Example 3) In Comparative Example 1, an e-cigarette cartridge was prepared in the same manner as in Comparative Example 2, using the aerosol-forming substrate prepared in Production Example 8 instead of the aerosol-forming substrate prepared in Production Example 6.

[0159] The non-tobacco plant compositions and e-cigarette cartridges obtained by the above method were evaluated as follows.

[0160] (Rating 1) For sheets prepared using the non-tobacco plant compositions created in Production Example 1, Production Example 5, Production Example 9, and Production Example 10, the length, width, thickness, and volume of each sheet were measured before and after drying by halogen lamp irradiation, and the changes were quantitatively measured.

[0161] The change in moisture content was measured using a halogen moisture meter (manufactured by Bangxi Instrument Technology Co. Ltd., model number: DHS-50-5).

[0162] A sheet of the non-tobacco plant composition was placed on the sample dish of a halogen moisture meter, and the sheet was heated from above the sample dish by a halogen lamp installed inside the heater cover. The heating temperature was set to 105°C, and the length, width, and thickness of the sheet of the non-tobacco plant composition were measured after a predetermined drying time, and the volume change was measured. The drying time was set to 0 minutes, 10 minutes, and 15 minutes, and the above measurements were taken at each time point.

[0163] The volume change rate is calculated by subtracting the volume of the non-tobacco plant composition sheet after drying for a predetermined time from the volume of the non-tobacco plant composition sheet before drying, and then dividing the result by the volume of the non-tobacco plant composition sheet before drying.

[0164] In the present invention, the length of the sheet of the non-tobacco plant composition before drying is L0, When the length of the sheet of the non-tobacco plant composition after a drying time of 10 minutes is defined as L10, the rate of change in the length of the sheet of the non-tobacco plant composition, La (%), is defined as follows. La(%) = (L0 - L10) / L0 × 100 Furthermore, when the length of the sheet of the non-tobacco plant composition after a drying time of 15 minutes is defined as L15, the rate of change in length Lb (%) of the sheet of the non-tobacco plant composition after a drying time of 15 minutes is defined as follows. Lb(%) = (L0 - L15) / L0 × 100

[0165] In the present invention, the width of the sheet of the non-tobacco plant composition before drying is W0, When the width of the sheet of the non-tobacco plant composition after a drying time of 10 minutes is defined as W10, the percentage change in width of the sheet of the non-tobacco plant composition, Wa (%), is defined as follows. Wa(%) = (W0 - W10) / W0 × 100 Furthermore, if the width of the sheet of the non-tobacco plant composition after a drying time of 15 minutes is W15, the percentage change in width Wb (%) of the sheet of the non-tobacco plant composition after a drying time of 15 minutes is defined as follows. Wb(%) = (W0 - W15) / W0 × 100

[0166] In this invention, the thickness of the sheet of the non-tobacco plant composition before drying is T0, When the thickness of the sheet of the non-tobacco plant composition after a drying time of 10 minutes is defined as T10, the percentage change in thickness of the sheet of the non-tobacco plant composition, Ta (%), is defined as follows. Ta(%) = (T0 - T10) / T0 × 100 Furthermore, if the thickness of the sheet of the non-tobacco plant composition after a drying time of 15 minutes is T15, the percentage change in thickness Tb (%) of the sheet of the non-tobacco plant composition after a drying time of 15 minutes is defined as follows. Tb(%) = (T0 - T15) / T0 × 100

[0167] In this invention, the volume of the sheet of non-tobacco plant composition before drying is V0, When the volume of the sheet of non-tobacco plant composition after a drying time of 10 minutes is defined as V10, the volume change rate Va (%) of the sheet of non-tobacco plant composition is defined as follows. Va(%) = (V0 - V10) / V0 × 100 Furthermore, if the volume of the sheet of the non-tobacco plant composition after a drying time of 15 minutes is V15, the volume change rate Vb(%) of the sheet of the non-tobacco plant composition after a drying time of 15 minutes is defined as follows. Vb(%) = (V0 - V15) / V0 × 100

[0168] In (Evaluation 1), the results obtained by measuring the length, width, thickness, and volume are as follows: Figure 9 shows a graph illustrating the rate of change in length. Figure 10 shows a graph illustrating the rate of change in volume.

[0169] After a drying time of 10 minutes, the percentage change in volume Va (%) was 86.7% for the non-tobacco plant composition sheet of Production Example 5 (which did not contain microcrystalline cellulose), compared to 89.4% for the non-tobacco plant composition sheet of Production Example 1 (which contained microcrystalline cellulose). Furthermore, the non-tobacco plant composition sheet of Production Example 10 had a volume change of 86.9%. After a 15-minute drying time, the percentage change in volume Vb (%) was 85.5% for the non-tobacco plant composition sheet of Production Example 5 (which did not contain microcrystalline cellulose), compared to 88.0% for the non-tobacco plant composition sheet of Production Example 1 (which contained microcrystalline cellulose). Furthermore, the non-tobacco plant composition sheet of Production Example 10 had a volume change of 85.7%.

[0170] After a drying time of 10 minutes, the percentage change in length (La(%)) was 92.7% for the non-tobacco plant composition sheet of Production Example 5, which did not contain microcrystalline cellulose, compared to 93.6% for the non-tobacco plant composition sheet of Production Example 1, which contained microcrystalline cellulose. Furthermore, the non-tobacco plant composition sheet of Production Example 10 had a percentage change of 92.8%. After a 15-minute drying time, the percentage change in length (Lb) was 91.8% for the non-tobacco plant composition sheet of Production Example 5 (which did not contain microcrystalline cellulose), compared to 92.7% for the non-tobacco plant composition sheet of Production Example 1 (which contained microcrystalline cellulose). Furthermore, the non-tobacco plant composition sheet of Production Example 10 had a change in length of 91.9%.

[0171] After a drying time of 10 minutes, the percentage change in width Wa (%) was 94.8% for the non-tobacco plant composition sheet of Production Example 5, which did not contain microcrystalline cellulose, compared to 96.2% for the non-tobacco plant composition sheet of Production Example 1, which contained microcrystalline cellulose. Furthermore, the non-tobacco plant composition sheet of Production Example 10 had a percentage change of 95.0%.

[0172] After a 15-minute drying time, the percentage change in width (Wb) was 94.7% for the non-tobacco plant composition sheet of Production Example 5 (which did not contain microcrystalline cellulose), compared to 96.0% for the non-tobacco plant composition sheet of Production Example 1 (which contained microcrystalline cellulose). Furthermore, the non-tobacco plant composition sheet of Production Example 10 showed a change in width of 94.9%.

[0173] After a drying time of 10 minutes, the percentage change in thickness (Ta) was 98.6% for the non-tobacco plant composition sheet of Production Example 5, which did not contain microcrystalline cellulose, compared to 99.3% for the non-tobacco plant composition sheet of Production Example 1, which contained microcrystalline cellulose. Furthermore, the non-tobacco plant composition sheet of Production Example 10 had a thickness of 98.8%. After a 15-minute drying time, the percentage change in thickness Tb (%) was 98.3% for the non-tobacco plant composition sheet of Production Example 5 (which did not contain microcrystalline cellulose), compared to 99.0% for the non-tobacco plant composition sheet of Production Example 1 (which contained microcrystalline cellulose). Furthermore, the non-tobacco plant composition sheet of Production Example 10 had a thickness of 98.5%.

[0174] Furthermore, when the length, width, thickness, and volume of the sheet of the non-tobacco plant composition prepared in Production Example 9, in which methylcellulose was added instead of microcrystalline cellulose, were measured before and after drying by similar halogen lamp irradiation, the changes were the same as in Production Example 5. Furthermore, methylcellulose does not have a microcrystalline structure. The results of Evaluation 1 above are summarized in Table 2 below. [Table 2]

[0175] (Rating 2) The following evaluations were conducted on e-cigarette cartridges. The following describes the general specifications of the e-cigarette device used. The e-cigarette device used was the IQOS® heated tobacco product manufactured by Philip Morris. The general specifications of the e-cigarette are as follows: The heating element (211) is 4.5 mm wide, 12 mm long to the tip, and 0.4 mm thick. The inner diameter of the insertion part (210) is 7 mm, which is approximately equal to the outer diameter of the e-cigarette cartridge. The heating element (211) is heated by power supplied from a battery (not shown) located inside the e-cigarette device (200), reaching a temperature of approximately 370°C. The built-in control system ensures that one e-cigarette cartridge is consumed after 14 puffs. When the e-cigarette cartridge of this embodiment is inserted, the portion of the e-cigarette cartridge that appears to the outside from the downstream side of the e-cigarette device is approximately 20 mm.

[0176] After smoking the e-cigarette cartridges manufactured in this embodiment and comparative example using the e-cigarette device, a drop test of the contents was performed. The post-smoking filler drop test was evaluated as follows: After smoking, one end (10) of the e-cigarette cartridge was pointed vertically downwards and shaken up and down to check for any ejection or fall of the filler. The evaluation criteria are as follows: Rank A: No instances of jumping out or falling observed. Rank B: May involve sudden jumps or falls. The test results obtained using method (Evaluation 2) are shown in Table 1 below.

[0177] (Rating 3) The shedding of the filling material after storage at room temperature for a specified period was evaluated as follows. The prepared e-cigarette cartridges were placed in a cardboard box measuring 70mm (long side), 14mm (short side), and 45mm (height), with the aerosol-forming substrate facing the bottom. The prepared boxes containing the e-cigarette cartridges were then left in a 45°C environment for two weeks. The following evaluation will then be conducted. The e-cigarette cartridge was removed from the cardboard box, and one end of the e-cigarette cartridge (10) was pointed vertically downwards to check for any leakage or dropping of the contents. The evaluation criteria are as follows: Rank A: No instances of jumping out or falling observed. Rank B: May involve sudden jumps or falls. The test results obtained using method (Evaluation 3) are shown in Table 1 below. [Table 1]

[0178] (Rating 5) For the fillers prepared in Manufacturing Examples 3, 7, and 10, the length, width, thickness, and volume of the fillers were measured before and after drying by halogen lamp irradiation, and the changes were quantitatively measured. Furthermore, the moisture content was measured using the same type of halogen moisture meter (manufactured by Bangxi Instrument Technology Co. Ltd., model number: DHS-50-5) as in (Evaluation 1), and the measurement method was carried out in the same manner as in (Evaluation 1).

[0179] In this invention, the length of the filler before drying is L'0, If we define L'10 as the length of the filling after a drying time of 10 minutes, The rate of change in length of the packing material, L'a(%), is defined as follows: L'a(%)=(L'0-L'10) / L'0×100 Furthermore, if the length of the filling material after a drying time of 15 minutes is L'15, the rate of change in length of the filling material after a drying time of 15 minutes, L'b(%), is defined as follows. L'b(%)=(L'0-L15) / L'0×100

[0180] In this invention, the width of the filler before drying is W'0, When the width of the filler after 10 minutes of drying time has elapsed is defined as W’10, The width change rate W’a(%) of the filler is defined as follows. W’a(%)=(W’0 - W’10) / W’0×100 Also, when the width of the filler after 15 minutes of drying time has elapsed is W’15, the width change rate W’b(%) of the filler after 15 minutes of drying time is defined as follows. W’b(%)=(W’0 - W’15) / W’0×100

[0181] In the present invention, when the thickness of the filler before drying is T’0, and the thickness of the filler after 10 minutes of drying time has elapsed is defined as T’10, The thickness change rate T’a(%) of the filler is defined as follows. T’a(%)=(T’0 - T’10) / T’0×100 Also, when the thickness of the filler after 15 minutes of drying time has elapsed is T’15, the thickness change rate T’b(%) of the filler after 15 minutes of drying time is defined as follows. T’b(%)=(T’0 - T’15) / T’0×100

[0182] In the present invention, when the volume of the filler before drying is V’0, and the volume of the filler after 10 minutes of drying time has elapsed is defined as V’10, The volume change rate V’a(%) of the filler is defined as follows. V’a(%)=(V’0 - V’10) / V’0×100 Also, when the volume of the filler after 15 minutes of drying time has elapsed is V’15, the volume change rate V’b(%) of the filler after 15 minutes of drying time is defined as follows. V’b(%)=(V’0 - V15) / V’0×100

[0183] In (Evaluation 4), the results obtained by measuring the length, width, thickness, and volume are as follows: Furthermore, Figure 11 shows a graph illustrating the rate of change in length. Figure 12 shows a graph illustrating the rate of change in volume. Figure 13 shows a graph illustrating the rate of change in width.

[0184] After 10 minutes of drying, the percentage change in volume V'a (%) was 87.9% for the filler in Production Example 7, which does not contain microcrystalline cellulose, compared to 94.3% for the filler in Production Example 3, which contains microcrystalline cellulose. The filler in Production Example 10 was 88.1%. After 15 minutes of drying, the percentage change in volume V'b (%) was 82.9% for the filler in Production Example 7, which does not contain microcrystalline cellulose, compared to 91.5% for the filler in Production Example 3, which contains microcrystalline cellulose. The filler in Production Example 10 was 83.1%.

[0185] After 10 minutes of drying, the percentage change in length L'a (%) was 95.0% for the filler in Production Example 7, which did not contain microcrystalline cellulose, compared to 96.3% for the filler in Production Example 3, which contained microcrystalline cellulose. The filler in Production Example 10 was 95.2%. After 15 minutes of drying, the percentage change in length L'b (%) was 94.1% for the filler in Production Example 7, which did not contain microcrystalline cellulose, compared to 96.0% for the filler in Production Example 3, which contained microcrystalline cellulose. The filler in Production Example 10 was 94.2%.

[0186] After 10 minutes of drying, the percentage change in width W'a (%) was 93.7% for the filler in Production Example 7 (without microcrystalline cellulose), compared to 98.7% for the filler in Production Example 3 (with microcrystalline cellulose). The filler in Production Example 10 was 93.9%. After 15 minutes of drying, the percentage change in width W'b (%) was 89.4% for the filler in Production Example 7 (without microcrystalline cellulose), compared to 96.4% for the filler in Production Example 3 (with microcrystalline cellulose). The filler in Production Example 10 was 89.6%.

[0187] After a drying time of 10 minutes, the percentage change in thickness T'a (%) was 98.6% for the filler in Production Example 7, which does not contain microcrystalline cellulose, compared to 99.3% for the filler in Production Example 3, which contains microcrystalline cellulose. Furthermore, the non-tobacco plant composition sheet in Production Example 10 had a percentage change of 98.8%. After a drying time of 15 minutes, the percentage change in thickness T'b (%) was 98.3% for the filler in Production Example 7, which does not contain microcrystalline cellulose, compared to 99.0% for the filler in Production Example 3, which contains microcrystalline cellulose. Furthermore, the filler in Production Example 10 had a percentage change of 98.5%.

[0188] Furthermore, when the length, width, thickness, and volume of the filler prepared in Production Example 9, in which methylcellulose was added instead of microcrystalline cellulose, were measured under the same halogen lamp irradiation conditions, the changes were the same as in Production Example 7. Furthermore, methylcellulose does not have a microcrystalline structure. The results for a rating of 4 are summarized in Table 3. [Table 3]

[0189] The embodiment described above provides the following effects. The electronic cigarette filler and electronic cigarette cartridge made from the non-tobacco plant composition of the present invention can reduce shrinkage and volume changes of the electronic cigarette filler during manufacturing and storage. By reducing shrinkage and volume changes of the electronic cigarette filler, the tendency for the electronic cigarette filler to fall out of the electronic cigarette cartridge can be reduced, and the voids in the electronic cigarette filler through which aerosols pass can be maintained at a constant size regardless of the storage period and temperature conditions after manufacturing, thereby maintaining a suitable user experience.

[0190] As described above, embodiments to which the present invention is applied have been explained, but the present invention is not limited to these embodiments. The present invention can be variously modified based on the configurations described in the claims, and those are also within the scope of the present invention.
