Description

[Technical Field]

[0001] The present invention relates to an electronic cigarette cartridge and a filler for use in an electronic cigarette. [Background technology]

[0002] In recent years, in line with the trend toward smoking cessation, electronic cigarette products have become popular, allowing users to enjoy tobacco without using a flame by heating a cartridge containing tobacco components and inhaling the vaporized tobacco components. One such smoking article proposed is an electronic cigarette cartridge that uses a sheet containing glycerin or the like as an aerosol-forming substrate. Such an electronic cigarette cartridge is configured so that the aerosol-forming substrate can be penetrated by a heating blade, and a smoking article has been proposed that allows smoking by heating (Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6000451 Summary of the Invention [Problem to be solved by the invention]

[0004] Furthermore, the aerosol-forming substrate of the present invention must be appropriately filled with the filler. For example, if the filling rate is less than 60% and the filling amount is too small, sufficient aerosol generation by heating will be insufficient, and the resistance during inhalation when the user smokes will be too low, resulting in an unsatisfactory smoking experience. Furthermore, a filling rate of 65% or more will tend to improve the smoking experience. Conversely, if the filling rate is greater than 90% and the filling amount is too high, the filler will become too clogged, making it difficult for the user to smoke, increasing the resistance when inserting the heating element, or damaging the electronic cigarette cartridge. [Means for solving the problem]

[0005] In order to solve the above problem, the invention described in claim 1 is characterized in that an electronic cigarette cartridge has an aerosol-forming substrate at one end into which a heating element is inserted and a mouthpiece at the other end, the aerosol-forming substrate and the mouthpiece are surrounded by a packaging member, and at least the aerosol-forming substrate has a filler surrounded by a wrapping member.

[0008] The invention described in claim 4 is the invention described in claim 1, wherein the filler is in a sheet shape and has at least one of a wrinkled, pleated, and gathered shape.

[0009] The invention described in claim 5 is the invention described in claim 1, wherein the filler is in the form of a sheet and has at least one of a shape folded along the longitudinal direction of the electronic cigarette cartridge and a roll-shaped shape wound inside.

[0011] A seventh aspect of the present invention is the first aspect of the present invention, wherein the filler has an aerosol former that generates an aerosol when heated, and a support that supports the aerosol former.

[0012] The invention described in claim 8 is the invention described in claim 7, wherein the carrier is at least one selected from rubber, cellulose binder, and polysaccharide, and the filler includes inorganic particles.

[0013] A ninth aspect of the present invention is the eighth aspect of the present invention, wherein the inorganic particles contain diatomaceous earth. [Effects of the Invention]

[0014] By attaching inorganic particles to the surface of the aerosol-forming material, it is possible to prevent the aerosol-forming material from adhering or sticking to itself even when stored in a high-temperature environment.

[0016] Hereinafter, an embodiment of the present invention will be described. The aerosol-forming material used in the present invention may be, for example, one manufactured as follows: Materials for forming the aerosol-forming material include a carrier for supporting the aerosol former, the aerosol former, and a flavor additive, which is used as needed.

[0017] As a carrier for carrying the aerosol former, various parts of tobacco plants or non-tobacco plants (e.g., roots, stems, leaves, flowers, fruits, skin, seeds, tree trunks, or tree branches) can be used, and they are preferably used in a dried and crushed form.

[0018] In addition to the plant parts mentioned above, carriers that can be used to support the aerosol former include gums such as guar gum, xanthan gum, gum arabic, 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, and conjugate base salts of organic acids such as sodium alginate, agar, and pectin; and combinations thereof.

[0019] Examples of aerosol formers that can be used 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 dodecanedionate, and dimethyl tetradecanedione, with glycerin and propylene glycol being particularly preferred. These are used in an amount of 1% by mass to 80% by mass, and more preferably 10% by mass to 40% by mass, based on the aerosol former.

[0020] In addition to the aerosol former carrier and aerosol former, flavor additives that add flavor as needed are also preferably used. Examples of flavor additives include mint, cocoa, coffee, and black tea extracts. Furthermore, when producing an aerosol-forming material using the above materials, various additives such as water, ethyl alcohol, and thickeners may be added in addition to the above for preferable production.

[0021] For example, when preparing the filler as a sheet, methods include preparing a sheet containing the above-mentioned tobacco material and adding an aerosol former to the prepared sheet, as described in JP-A-2010-520764, or combining an aerosol former with cellulose fiber and tobacco powder to form a slurry, which is then formed into a sheet, as described in JP-A-2017-529848.

[0022] When the filler is to be made into a rod or strip shape, the material of the carrier that supports the aerosol former as described above is mixed with the aerosol former and water, and the resulting sheet is suitably moistened and then molded or cut into the desired rod or strip shape.

[0023] The reason why inorganic particles are preferably used in the present invention is that when the aerosol-forming substrate in the present invention is heated, inorganic substances are less likely to be decomposed by the heating.

[0024] The presence of inorganic particles on the surface of the filler prevents direct contact between fillers containing the aerosol former. By creating such a situation, adhesion between the aerosol-forming materials can be prevented even if the aerosol former seeps onto the surface of the aerosol-forming material and increases in amount due to vibration or high temperature conditions to which the electronic cigarette cartridge of the present invention is exposed during transportation or storage.

[0025] To achieve this effect, the inorganic particles preferably have a diameter of approximately 1 μm or more and 1000 μm or less. Furthermore, if the diameter is 5 μm or more, it is more preferable because it functions more effectively as a spacer between fillers. Furthermore, if the diameter is 50 μm or less, it is more preferable because it has a sufficient spacer effect and can be sufficiently packed with fillers.

[0026] In the present invention, the diameter of an inorganic particle refers to the diameter of a circle equivalent to the area of ​​a projected image of the inorganic particle taken using an optical microscope or, if necessary, an electron microscope. That is, the diameter of the particle is defined as the diameter of the circle having the same area as the projected image of the inorganic particle. The presence of inorganic particles on the surface of the aerosol-forming material can be determined by, for example, disassembling the aerosol-forming substrate and observing the surface of the aerosol-forming material on approximately 10 images at a magnification of approximately 500 and a field of view of 100 μm × 100 μm. The magnification may be increased as needed. It is also preferable to confirm that the particles are inorganic by using a scanning electron microscope equipped with XMA (X-ray microanalysis).

[0027] In the present invention, the particle size of the inorganic powder is measured using, for example, a laser diffraction / scattering particle size distribution analyzer. The powder sample is preferably measured wet. For example, a Microtrac MT3300III manufactured by Microtrac Bell is used. In the present invention, the average particle size refers to the diameter at 50% of the cumulative volume-based distribution in the range of 0.02 μm to 2000 μm.

[0028] One example of a method for adhering inorganic particles to the surface of an aerosol-forming material is to add an inorganic powder to the aerosol-forming material and mix it. The inorganic powder added to the aerosol-forming material preferably has an average particle diameter of 1 μm or more, more preferably 5 μm or more, and preferably 10 μm or more, since this enhances the effects of the present invention. Furthermore, an average particle diameter of 100 μm or less makes it easier to maintain adhesion to the surface of the aerosol-forming material, and an average particle diameter of 40 μm or less is preferable, since it provides a sufficient spacer effect and allows for sufficient filling of the filler.

[0029] The amount of inorganic powder added is preferably 0.001 to 10 parts by mass per 100 parts by mass of filler. More preferably, it is 0.01 parts by mass or more, which allows for a sufficient spacer effect. A more preferred range is 0.05 parts by mass or more. Furthermore, it is preferable that it is 5 parts by mass or less, since this provides a spacer effect and allows for sufficient filling of the filler. A more preferred range is 2 parts by mass or less.

[0030] Furthermore, in the present invention, it has been found that when an aerosol-forming substrate is formed using an aerosol-forming material having inorganic particles present on the surface, this surprisingly has the effect of reducing dirt adhering to the heating element after use.

[0031] In particular, when the average particle diameter of the inorganic powder to be added is 1 μm or more and 40 μm or less, a good effect is achieved, and when it is 5 μm or more, an even greater effect of reducing deposits is achieved. When the amount of inorganic powder to be added is 0.01 parts by mass or more and 5 parts by mass or less, a good effect is achieved, and when it is 0.1 parts by mass or more, an even greater effect of reducing deposits is achieved. The mechanism of this action is assumed to be that the inorganic particles exert a polishing effect on the surface when the heating element is attached or detached, or scavenge dirt, or that the spacer effect of the inorganic particles reduces the probability of direct contact between the heating element surface and the aerosol-forming material during heating, thereby reducing dirt.

[0032] Examples of inorganic substances that can be used as the inorganic particles of the present invention include metal chlorides such as sodium chloride and potassium chloride; metal oxides such as magnesium oxide, calcium oxide, titanium oxide, iron oxide, and alumina; metal carbonates such as magnesium carbonate and calcium carbonate; metal sulfates such as magnesium sulfate and calcium sulfate; metal phosphates such as calcium phosphate; and titanates such as potassium titanate and magnesium titanate, which can be used alone or in combination. While the above examples of inorganic substances that can be used in the present invention have been given, the inorganic particles of the present invention are not limited to the above inorganic substances and also include salts with other metals. Furthermore, silicon oxides such as zeolite, colloidal silica, and fumed silica can also be used. Magnesium carbonate, calcium carbonate, silicon oxide, and alumina are particularly preferred.

[0033] Natural materials containing the above-mentioned inorganic substances can also be used, such as diatomaceous earth and vermiculite.

[0034] Furthermore, the aerosol-forming substrate of the present invention must be appropriately filled with the filler. If the filling amount is too small, the aerosol generated by heating will be insufficient, resulting in an unsatisfactory smoking experience for the user. Conversely, if the filling amount is too large, the filler will become too clogged, making it difficult for the user to smoke or increasing the resistance when inserting the heating element, resulting in damage to the electronic cigarette cartridge.

[0035] In the present invention, the preferred shapes of the filler are as follows. As an example of one preferred shape, FIG. 3 shows a rod- or strip-shaped filler disposed in the covering member (151) along the longitudinal direction of the aerosol-forming substrate. As another preferred shape, FIG. 6 shows a view of the aerosol-forming substrate (110) from one end, in which the aerosol-forming substrate (110) has a sheet-shaped filler (112) folded in the covering member (151) along the longitudinal direction of the electronic cigarette cartridge. As yet another preferred shape, FIG. 7 shows a view of the aerosol-forming substrate (110) from one end, in which the aerosol-forming substrate (110) has a sheet-shaped filler (113) wound in the covering member (151) along the longitudinal direction of the electronic cigarette cartridge in a roll shape.

[0036] The appropriate range of the filling amount of the filler can be evaluated by a method of calculating the area ratio of the sheet-like aerosol-forming material to the cross section of the aerosol-forming substrate. In this case, if the state of the aerosol-forming substrate as viewed from one end is the same as the cross section, this can be used.

[0037] For example, it can be determined by using a digital microscope to evaluate the filler and the voids without filler, and can be measured as follows. A digital microscope (Keyence VHX-2000) was used, with a magnification of 100x and projected onto a display. The image analysis range was the area where only the filler and the voids without filler appeared. In this case, the observation sample diameter was 7.0 mm, and the dimensions were 3.5 mm wide and 2.6 mm high. For this range, image analysis was performed using the accompanying software, with the "automatic measurement mode" and the "extraction mode" set to "brightness." Measurement was performed using "standard," the "extraction parameter" set to "bright," and the "threshold" selected to separate the filler and voids observed. The filling rate was calculated as the ratio of the filler to the entire measurement range.

[0038] Thus, the packing ratio is preferably 60% or more and 90% or less. More preferably, it is 65% or more, and even more preferably, it is 70% or more. When attempting to increase such a packing ratio, the packing materials often tend to adhere to each other, which is why the present invention is useful.

[0039] The filler prepared as described above is used in the electronic cigarette body as an electronic cigarette cartridge as follows.

[0040] Figure 1 illustrates an example of how an electronic cigarette cartridge is used. When a user uses the electronic cigarette cartridge (100), it is attached to an electronic cigarette body (200). The electronic cigarette body (200) is provided with an insertion part (210) into which the electronic cigarette cartridge (100) is inserted.

[0041] A heating element (211) is provided in the center of the bottom of the insertion portion (210), and the heating element (211) has a pin-like or blade-like 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 portion (210) of the electronic cigarette body (200).

[0042] The heating element (211) generates heat directly or indirectly using power supplied from a battery (not shown) installed within the electronic cigarette body (200). The heat from the heating element (211) warms the aerosol-forming substrate (110), generating an aerosol containing aromatic components. The generated aerosol is then transported to the mouthpiece (140) via the support element (300) and the aerosol-transporting member (130), which will be described below. When the user inhales through the mouthpiece (140), the aromatic components reach the user's mouth. Hereinafter, for purposes of describing the present invention, the aerosol-forming substrate (110) side of the electronic cigarette cartridge will be referred to as the upstream side (10), and the mouthpiece side will be referred to 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.

[0043] Although FIG. 1 illustrates a case where the heating element (211) has one pin-shaped or blade-shaped member, an example of another embodiment is a heating element (211) having multiple pin-shaped or blade-shaped members.

[0044] 2 shows an example of the structure of an electronic cigarette cartridge 100. The structure will be described from the side where the heating element 211 is inserted, i.e., from the upstream side 10 to the downstream side 20, including the aerosol-forming substrate 110, the support element 300, the transfer member 130, and the mouthpiece 140.

[0045] The support element 300 supports the aerosol-forming substrate 110. The support element 300 is disposed adjacent to the aerosol-forming substrate 110, and the side portion 160 of the support element 300 contacts the packaging member 150 located on the periphery of the electronic cigarette cartridge 100. The side portion 160 is fixed to the inner surface of the packaging member 150, for example, by adhesive.

[0046] Furthermore, the support element (300) is preferably made of, for example, silicone, but is not limited to silicone and may be made of other materials that are highly heat resistant.

[0047] As shown in FIG. 3, the filler (111) manufactured as the aerosol-forming substrate (110) preferably has a rod-like or strip-like shape, for example, and is packed so that the shape of the filler (111) is aligned along the longitudinal direction of the shape during packing. Here, an example is shown in which the filler is packed into a cylindrical wrapping member (151). As the wrapping member (151), a cylindrical piece of paper such as cigarette paper can be used. Alternatively, the packaging member (150) may also serve as the wrapping member (151). This stabilizes the airflow, making it easier for the user to inhale the aromatic components from the aerosol-forming substrate (110).

[0048] 4 shows the electronic cigarette cartridge 100, in which the aerosol-forming substrate 110, transfer member 130, mouthpiece 140, and a support element 300 (described below) are arranged adjacent to each other in the order of aerosol-forming substrate 110, support element 300, transfer member 130, and mouthpiece 140, and wrapped around a wrapping element 150 such as tobacco paper to form a wound rod. A small amount of adhesive is applied to the side 160 of the support element. Next, an example of use of the electronic cigarette cartridge of the present invention will be described in detail.

[0049] 1, 2, 3 and 4 show examples of the use and appearance of an electronic cigarette cartridge.

[0050] As shown in FIG. 2, the electronic cigarette cartridge (100) has, for example, a rod-like or cylindrical appearance.

[0051] As shown in Figure 2, the interior of the electronic cigarette cartridge (100) has an aerosol-forming substrate (110) at one end, a support element (300) and a transfer member (130) arranged in this order toward the mouthpiece (140) at the other end, and these are packaged in a packaging member (150).

[0052] The aerosol-forming substrate (110) is a filler for an electronic cigarette cartridge. When heated, the aerosol-forming substrate (110) generates an aerosol containing aromatic components of the plant from which the filler is derived.

[0053] As shown in FIG. 3, when the filler serving as the aerosol-forming substrate (110) has a shape such as a flake, a strip, or a rod, with the long side approximately 2 to 20 times the short side, the filler (111) is packed so that its longitudinal direction is aligned with the longitudinal direction of the cartridge during filling. This improves the airflow and facilitates inhalation. Note that FIG. 3 is a view of the electronic cigarette cartridge from the end where the aerosol-forming substrate (110) is located, with a partial perspective view to allow the filler (111) inside the cartridge to be seen. However, in both cases, it is preferable that the maximum length be approximately 1 to 20 mm. This is because if the maximum length is too large, it may be too large when filling the cartridge, making it difficult to handle. Of course, other fillers, such as flat, uniformly shaped fillers, can be easily handled by rolling them up.

[0054] As another preferred form of the aerosol-forming substrate, a sheet formed by crinkling, pleating, gathering or folding can also be used.

[0055] Like rod-shaped fillers, fibrous fillers are packed so that the length of the fibers is aligned with the longitudinal direction of the cartridge, improving the flow of sucked air.

[0056] A porous filler is one of the preferred forms because it is porous when packed into the cartridge, which improves the flow of air when sucked in. Porosity can be achieved, for example, by piercing the dried sheet with multiple needles several times, but other methods are also possible.

[0057] The cartridges can be flat, such as flakes, squares, rectangles, or diamonds, and powder, granule, or pellet fillers can be easily dropped into the cartridge opening. This is also preferable because it is easy to precisely adjust the amount of material to be filled into the cartridge (filling amount), and the air flow during inhalation can be easily adjusted depending on the amount of material filled. Taking measures to prevent the cartridge opening from falling out, such as by covering it with a lid, makes the cartridge even more suitable for use.

[0058] Block-shaped fillings have good thermal conductivity and are easy to extract aromatic components, making them a preferred form. The blocks may also be made larger to facilitate storage. In this case, the blocks can be reshaped into smaller blocks, rods, granules, or other shapes during filling.

[0059] The effects of the present invention can be achieved by having inorganic particles present on the surface of the fillers having various shapes as exemplified above.

[0060] The paste-like filling material can be squeezed into the cartridge, so that, for example, the paste can be applied to the unfolded packaging member (150) and then rolled up together with the packaging member (150) to form a cartridge.

[0061] The support element (300) supports the aerosol-forming substrate (110). The support element (300) is disposed adjacent to the aerosol-forming substrate (110) and has an airflow hole or notch in the center or on the side, allowing the aerosol generated from the aerosol-forming substrate (110) to flow toward the mouthpiece.

[0062] The mouthpiece 140 is located adjacent to the transfer member 130 and at the other end of the electronic cigarette cartridge 100. The mouthpiece 140 may include a filter, such as a cellulose acetate filter, to remove particulates. The aroma components that pass through the filter of the mouthpiece 140 are inhaled by the user.

[0063] Comparing the presence and absence of the transfer member (130), the absence of the transfer member (130) results in better breathability and makes it easier to inhale the generated aromatic components. On the other hand, it is also preferable to include the transfer member (130) to add a function for 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 in the mouthpiece can also serve as a cooling function, thereby reducing the number of parts. The transfer member (130) can be a hollow tubular member or a crimped polymer sheet wound in the longitudinal direction of the electronic cigarette cartridge.

[0064] 5(1) shows a configuration in which the aerosol-forming substrate 110 and the support element 300 are in contact with each other, which is a preferred configuration because it can stably support the aerosol-forming substrate 110. In addition, the simple configuration offers great advantages in terms of manufacturing.

[0065] 5(2) shows a configuration in which a partition member (160) is provided between the aerosol-forming substrate (110) and the support element (300), and the aerosol-forming substrate (110) and the support element (300) are in contact with each other via the partition member (160). The partition member (160) is preferably made of a breathable material such as a filter or paper, and is preferably one that breaks when the heating element (211) is inserted. Providing such a partition member is effective in preventing the aerosol-forming substrate (110) from moving in the electronic cigarette cartridge due to logistics such as transportation.

[0066] As shown in Figure 5(3), a configuration in which a lid (170) is placed on the side of the aerosol-forming substrate (110) where the heating element (211) is inserted is also preferred. This is effective in preventing the aroma of the aerosol-forming substrate (110) from dissipating. Furthermore, it is effective in preventing the aerosol-forming substrate (110) from falling out of the electronic cigarette cartridge due to logistics such as transportation. Examples of materials for the lid (170) include filters, paper, and sponge. When a heating element is inserted, it is also preferred to cut one or more slits in the lid (170) or to provide a circular or polygonal guide hole at the location where the heating element is inserted.

[0067] In particular, when the aerosol-forming substrate (110) is in the form of particles such as powder, granules, flakes, or pellets, it is preferable to provide the partition member (160) or the lid (170), and more preferably to provide both.

[0068] Next, non-tobacco plants used as raw materials will be described. Non-tobacco plants that can be used in this embodiment are not particularly limited as long as they are plants other than tobacco. Various parts of plants can be used, for example, roots (including bulbs, tuberous roots (potatoes), bulbs, etc.), stems, tubers, bark (including stem bark, bark, etc.), leaves, flowers (including petals, pistils, stamens, etc.), tree trunks and branches, etc.

Stems include asparagus, bamboo shoots, burdock, radishes, and yacon.

[0070] The above-mentioned potatoes and the plants listed below contain carbohydrates and are preferably used as at least a part of the material for the filler 111. For example, starch includes corn starch, potato starch, sweet potato starch, tapioca starch, etc., and examples of use include thickeners, stabilizers, etc. These starches can be crosslinked to improve acid resistance, heat resistance, shear resistance, etc., esterified or etherified to improve storage stability and promote gelatinization, etc., and oxidized to improve transparency, film properties, storage stability, etc.

[0071] Tamarind seed gum, guar gum, and locust bean gum can be obtained from plant seeds, gum arabic and karaya gum from sap, pectin from fruits, and konjac mannan and soy polysaccharides, which are mainly composed of cellulose and agarose, can be obtained from other plants. Furthermore, modified products such as cationized guar gum can be used.

[0084] Furthermore, extracts of the above-mentioned non-tobacco plants, so-called extracts, can also be used. The extracts may be in the form of liquid, starch syrup, powder, granules, solution, etc.

[0085] The present invention will be described in detail below. (Production Example 1) 100 parts by weight of dried and crushed black tea leaves 20 parts by weight of dried and crushed licorice 10 parts by weight of dried and crushed lotus leaves were charged into a mixer and dry mixed for 5 minutes.

[0086] The dry mixture is Polypropylene glycol 25 parts by mass Glycerin 25 parts by mass Carboxymethylcellulose sodium salt 5 parts by mass Menthol 3 parts by weight 3 parts by mass of ethanol 200 parts by mass of water were charged into the mixer and wet-mixed for 15 minutes.

[0087] In the process of forming a sheet from the slurry obtained as described above, a specified amount of the slurry was poured into a frame equipped with an appropriate tray to produce a water-containing sheet. In this example, the water content of the water-containing sheet was approximately 95% when the water content of the slurry was 100%.

[0088] Subsequently, the water-containing sheet was passed three times through press rolls with a predetermined clearance to be molded, and then 7 parts by mass of water per 100 parts by mass of the water-containing sheet that had been passed three times was added to the water-containing sheet, and the sheet was passed through the press rolls a further five times.

[0089] The formed moisture-containing sheet obtained as described above was then dried for 300 minutes at 35°C to produce a formed sheet for electronic cigarette filler with a moisture content of 20% by mass. A drying temperature of less than 50°C is preferred to preserve the flavor. More preferably, the drying temperature is less than 45°C, and even more preferably, less than 40°C. The thickness of the sheet can be adjusted as needed, but in this example, it was set to 0.5 mm. The sheet was cut into a length of 12 mm, a width of 1.5 mm, and a thickness of 0.5 mm to prepare an aerosol-forming material.

[0090] In (Production Example 2), the sheet was formed to a thickness of 1 mm, a length of 12 mm, a width of 1 mm and a thickness of 1 mm to form an aerosol-forming material.

[0091] (Production Example 3) Wood fiber 50 parts by mass 50 parts by mass of dried black tea leaves 5000 parts by mass of water The above was mixed to form a slurry.

[0092] This slurry was cast into a sheet with a thickness of 0.2 mm. The remaining water from the cast was concentrated and stored for use in the next step.

[0093] The sheet was dried and the following was added per 100 parts by mass of the sheet: Polypropylene glycol 10 parts by mass Glycerin 20 parts by mass 2 parts by mass of carboxymethylcellulose sodium salt Menthol (50% ethanol solution) 3 parts by weight 50 parts by weight of concentrated cast residue water was added and dried to form a sheet. The sheet was cut to form a sheet measuring 120 mm wide, 12 mm long and approximately 0.2 mm thick.

[0094] Example 1 One part by mass of calcium carbonate powder with an average particle size of 15 μm was added to and mixed with 100 parts by mass of the aerosol-forming material prepared in Production Example 1. Microscopic observation revealed that calcium carbonate particles with diameters of 10 μm to 50 μm had adhered to the material. 0.29 g of an aerosol-forming material having calcium carbonate particles on its surface was filled into a paper tube containing member with an inner diameter of 6.9 mm and a height of 12 mm to form an aerosol-forming substrate (110). An electronic cigarette cartridge like that shown in Figure 4 was prepared. A hollow tube with a through-hole at its center was used as the support element (300). The diameter of the bottom of the tube was 7 mm, and the through-hole forming the hollow portion was 3 mm. The material was cellulose acetate. The support element (300) functions to support the aerosol-forming substrate (110) against the insertion force when the heating element (211) is inserted, and the through-hole functions to guide the generated aerosol from the upstream side (10) to the downstream side (20) so that it reaches the user's mouth. The transfer member (130) was a gathered polymer sheet wrapped in paper to form a cylindrical shape with a bottom diameter of 7 mm and a height of 18 mm. The transfer member (130) has the function of guiding the generated aerosol from the upstream side (10) to the downstream side (20) so that it reaches the user's mouth, and also has the function of maintaining an appropriate temperature for the aerosol. The mouthpiece (140) used was a filter wrapped in paper to form a cylindrical shape with a base diameter of 7 mm and a height of 7 mm. The filling rate was measured and found to be 81%.

[0095] Example 2 One part by mass of calcium carbonate powder with an average particle size of 15 μm was added to and mixed with 100 parts by mass of the aerosol-forming material prepared in (Production Example 2). Microscopic observation revealed the presence of calcium carbonate particles with a diameter of 10 μm or more and 50 μm or less. 0.29 g of the aerosol-forming material having calcium carbonate particles on its surface was filled into a paper tube containing member with an inner diameter of 6.9 mm and a height of 12 mm, and an electronic cigarette cartridge was prepared in the same manner as in Example 1. The filling rate was measured and found to be 83%.

[0096] Example 3 The aerosol-forming material prepared in (Production Example 3) was placed on a table. Calcium carbonate powder with an average particle size of 15 μm was sprinkled evenly on the upper surface of the sheet at 1 part by mass per 100 parts by mass of the sheet. The sheet was then rolled up with the upper surface facing inward into a cylinder with a diameter of approximately 6.5 mm and a height of 12 mm. Microscopic observation revealed that calcium carbonate particles with a diameter of 10 μm to 50 μm were attached. 0.29 g of an aerosol-forming material having calcium carbonate particles on its surface was filled into a paper tube serving as a packaging member with an inner diameter of 6.9 mm and a height of 12 mm, and an electronic cigarette cartridge was produced in the same manner as in Example 1. The filling rate was measured and found to be 74%.

[0097] Example 4 One part by mass of magnesium carbonate powder with an average particle size of 10 μm was added to and mixed with 100 parts by mass of the aerosol-forming material prepared in (Production Example 1). Microscopic observation revealed that magnesium carbonate particles with diameters of 10 μm to 50 μm had adhered to the material. 0.29 g of an aerosol-forming material having calcium carbonate particles on its surface was filled into a paper tube serving as a packaging member with an inner diameter of 6.9 mm and a height of 12 mm, and an electronic cigarette cartridge was produced in the same manner as in Example 1. The filling rate was measured and found to be 80%.

[0098] Example 5 One part by mass of silicon oxide powder with an average particle size of 20 μm was added to and mixed with 100 parts by mass of the aerosol-forming material prepared in Production Example 1. Microscopic observation revealed that silicon oxide particles with diameters of 10 μm to 50 μm had adhered to the material. 0.29 g of an aerosol-forming material having silicon oxide particles on its surface was filled into a paper tube, which was a packaging member having an inner diameter of 6.9 mm and a height of 12 mm, and an electronic cigarette cartridge was produced in the same manner as in Example 1. The filling rate was measured and found to be 80%.

[0099] Example 6 One part by mass of alumina with an average particle size of 5 μm was added to and mixed with 100 parts by mass of the aerosol-forming material produced in Production Example 1. Microscopic observation revealed that alumina particles with diameters of 10 μm to 50 μm had adhered to the material. 0.29 g of an aerosol-forming material having alumina particles on its surface was filled into a paper tube as a packaging member with an inner diameter of 6.9 mm and a height of 12 mm, and an electronic cigarette cartridge was produced in the same manner as in Example 1. The filling rate was measured and found to be 81%.

[0100] Example 7 One part by mass of alumina with an average particle size of 2 μm was added to and mixed with 100 parts by mass of the aerosol-forming material produced in Production Example 1. Microscopic observation revealed that no alumina particles with a diameter of 10 μm or more and 50 μm or less were observed. 0.29 g of an aerosol-forming material having silicon oxide particles on its surface was filled into a paper tube as a packaging member with an inner diameter of 6.9 mm and a height of 12 mm, and an electronic cigarette cartridge was produced in the same manner as in Example 1. The filling rate was measured and found to be 81%.

[0101] Example 8 One part by mass of silicon oxide powder with an average particle size of 0.5 μm was added to and mixed with 100 parts by mass of the aerosol-forming material prepared in Production Example 1. Microscopic observation revealed no silicon oxide particles with a diameter of 10 μm or more and 50 μm or less. 0.29 g of an aerosol-forming material having silicon oxide particles on its surface was filled into a paper tube, which was a packaging member having an inner diameter of 6.9 mm and a height of 12 mm, and an electronic cigarette cartridge was produced in the same manner as in Example 1. The filling rate was measured and found to be 81%.

[0102] Example 9 One part by mass of silicon oxide powder with an average particle size of 47 μm was added to and mixed with 100 parts by mass of the aerosol-forming material prepared in Production Example 1. Microscopic observation revealed that silicon oxide particles with diameters of 10 μm to 50 μm had adhered to the material. An attempt was made to fill a paper tube containing a container member with an inner diameter of 6.9 mm and a height of 12 mm with 0.29 g of an aerosol-forming material having silicon oxide particles on its surface. However, due to difficulties in filling, the amount was reduced to 0.23 g. An electronic cigarette cartridge was produced in the same manner as in Example 1. The filling rate was measured and found to be 65%.

[0103] (Comparative Example 1) The aerosol-forming material prepared in (Production Example 1) was used as a filler as is to form an electronic cigarette cartridge as shown in FIG.

[0104] (Comparative Example 2) The aerosol-forming material prepared in (Production Example 2) was used as a filler as is to form an electronic cigarette cartridge as shown in FIG.

[0105] (Comparative Example 3) The aerosol-forming material prepared in (Production Example 3) was used as a filler as is to form an electronic cigarette cartridge as shown in FIG.

[0106] The electronic cigarette cartridge obtained as described above was evaluated as follows. The electronic cigarette body used will be outlined below. 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 portion (210) is 7 mm, approximately the same as the outer diameter of the electronic cigarette cartridge. The heating element (211) generates heat using power supplied from a battery (not shown) installed inside the electronic cigarette body (200), reaching a temperature of approximately 350°C. The built-in control system then determines that one electronic cigarette cartridge is consumed after 14 puffs. When the electronic cigarette cartridge of this example is inserted, the portion of the electronic cigarette cartridge that appears outside from the downstream side of the electronic cigarette body is approximately 20 mm. Evaluation 1: The prepared electronic cigarette cartridges were packed into a paper box measuring 70 mm long and 14 mm short, and 45 mm high, with the aerosol-forming substrate facing the bottom. The box containing the prepared electronic cigarette cartridges was then placed in a plastic bag and left at 40°C for two weeks. After that, the box was removed and left at room temperature and humidity for one day, and the following evaluation was performed. The contents were removed from the aerosol-forming substrate and checked to see if they had solidified. Rank A: The item falls apart when removed with tweezers Rank B: Can be loosened by pressing with tweezers Rank C: When pressed with tweezers, lumps remain Items rated C are likely to become difficult to insert into the electronic cigarette body due to long-term storage, etc.

[0107] Evaluation 2: In each example and comparative example, the ease and difficulty of creating an electronic cigarette cartridge was compared. If there are no particular comments in each example, it means that there are no problems.

[0108] Evaluation 3: The electronic cigarette cartridges of each Example were evaluated for dirt adhering to the heating element when used as shown in Figure 1. The evaluation was carried out as follows. Using the electronic cigarette cartridge of Comparative Example 1, 14 puffs were taken per cigarette. After a total of 10, 20, 30, 40, and 50 puffs had been taken, dirt adhering to the heating element was wiped off using gauze impregnated with ethanol. The degree of dirt increased as the number of puffs increased.

[0109] In contrast, the dirt was collected after 50 puffs were taken from the electronic cigarette cartridges made in this example, and the degree of dirt was compared and evaluated based on how many cigarettes in Comparative Example 1 it corresponded to.

[0110] The evaluation results are summarized in Table 1. [Table 1]

[0111] As described above, in the present invention, by having inorganic particles present on the surface of the aerosol-forming material, electronic cigarette cartridges that have been transported or stored in various environments can be used without any problems. Another advantage of the present invention is that it reduces contamination of the heating element due to use, thereby extending the frequency of cleaning and the lifespan of the electronic cigarette body.

[0112] The above-described embodiment provides the following advantages. In the present invention, by having inorganic particles present on the surface of the aerosol-forming material, electronic cigarette cartridges can be used without any problems even if they have been transported or stored in various environments.

[0113] Another advantage of the present invention is that it reduces contamination of the heating element due to use, thereby extending the frequency of cleaning and the lifespan of the electronic cigarette body.

[0114] However, because aerosol-forming substrates formed in sheet form contain glycerin and other ingredients, they can stick together and harden during transportation or storage in warehouses or stores. This hardening makes it difficult for the heating blade to penetrate. This can lead to damage to the electronic cigarette cartridge and the heating blade. Therefore, the object of the present invention is to prevent sticking and hardening during transportation or storage in warehouses or stores, thereby preventing damage to the electronic cigarette cartridge or the heating blade of the electronic cigarette body.

[0115] Although the embodiments to which the present invention is applied have been described above, the present invention is not limited to these embodiments. The present invention can be modified in various ways based on the configurations described in the claims, and these modifications are also within the scope of the present invention.
