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 order to comply with the trend towards smoking cessation, electronic cigarette products that allow users to enjoy tobacco by heating a cartridge containing tobacco components and inhaling the vaporized tobacco components without using a flame have become popular. As such a smoking article, an electronic cigarette cartridge has been proposed that uses a sheet containing glycerin or the like as an aerosol-forming substrate. Such an electronic cigarette cartridge is configured such that the aerosol-forming substrate can be penetrated by a heating blade, and a smoking article that is heated to smoke has been proposed (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] In addition, in the aerosol-forming substrate of the present invention, it is necessary to fill the filler appropriately. For example, if the filling rate is less than 60% and the filling amount is too small, sufficient aerosol generation by heating is insufficient, and the resistance during inhalation when the user smokes is too low, resulting in an insufficient smoking experience. Furthermore, if the filling rate is preferably 65% ​​or more, the smoking experience tends to be improved. On the other hand, if the filling rate is more than 90% and the filling amount is too large, the filling material becomes 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, in an electronic cigarette cartridge, an aerosol-forming substrate into which a heating element is inserted is provided at one end and a mouthpiece is provided 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 filling material surrounded by a wrapping member.

[0006] The invention described in claim 2 is the invention described in claim 1, wherein the filler has at least one of a rod shape, a strip shape, and a fiber shape.

[0007] The invention described in claim 3 is the invention described in claim 1, wherein the filler has at least one of the following shapes: porous, flake, square, rectangular, or diamond-shaped plate, powder, granule, pellet, block, grain, and paste.

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

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

[0010] The invention described in claim 6 is the invention described in any one of claims 1 to 5, further comprising a lid on the heating element insertion side of the covering member or the packaging member.

[0011] The invention described in claim 7 is the invention described in claim 1, wherein the filler has an aerosol former that generates an aerosol by heating, and a support that supports the aerosol former.

[0012] The invention described in claim 8 is the invention described in claim 7, in which the support 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. Effect of the Invention

[0014] By adhering inorganic particles to the surface of the aerosol-forming material, it is possible to prevent adhesion and adhesion between particles of the aerosol-forming material even when the material is stored in a high-temperature environment. Furthermore, by attaching inorganic particles to the surface of the aerosol-forming material, contamination of the heating element of the electronic cigarette body can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[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: Furthermore, materials forming the aerosol forming material include a support that supports the aerosol former, the aerosol former, and a flavor additive that 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, tree branches, etc.) can be used, preferably in a dried and crushed form.

[0018] In addition to the above-mentioned plant parts, the carrier for carrying the aerosol former may also be 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, sodium alginate, agar, and conjugate base salts of organic acids such as pectin; and combinations thereof.

[0019] As the aerosol former, glycerin, propylene glycol, sorbitol, triethylene glycol, lactic acid, diacetin (glycerin diacetate), triacetin (glycerin triacetate), triethylene glycol diacetate, triethyl citrate, isopropyl myristate, methyl stearate, dimethyl dodecanediate, dimethyl tetradecanediate, etc. can be used, with glycerin and propylene glycol being particularly preferred. These are used in an amount of 1% by mass or more and 80% by mass or less, and particularly preferably 10% by mass or more and 40% by mass or less, based on the aerosol former.

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

[0021] For example, when creating the filling material as a sheet, as described in JP2010-520764A, a sheet containing the above-mentioned tobacco material is created and an aerosol former is added to the created sheet, or as described in JP2017-529848A, an aerosol former is combined with cellulose fiber and tobacco powder to form a slurry, which is then formed into a sheet.

[0022] Furthermore, 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, the aerosol former, and water are mixed together to form a sheet having an appropriate moisture content, which is 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 unlikely to be decomposed by the heating.

[0024] When inorganic particles are present on the surface of the filler, the fillers containing the aerosol former do not come into direct contact with each other. By creating such a condition, even if the aerosol former seeps onto the surface of the aerosol forming material and the amount of the aerosol former increases due to vibration or high temperature conditions to which the electronic cigarette cartridge of the present invention is exposed during transportation or storage, adhesion between the aerosol forming materials can be prevented.

[0025] In order to obtain such an effect, it is preferable that the inorganic particles have a diameter of about 1 μm or more and 1000 μm or less. Furthermore, if it is 5 μm or more, it is preferable because it functions more preferably as a spacer between the fillers. Furthermore, it is even more preferable that it is 10 μm or more. Furthermore, if it is 50 μm or less, it is preferable because it has a sufficient spacer effect and can be sufficiently filled with the fillers.

[0026] In the present invention, the diameter of an inorganic particle refers to the diameter of a circle obtained by taking an image of the inorganic particle on the surface of a filler using an optical microscope or, if necessary, an electron microscope. In other words, the diameter of the particle is the diameter of a circle equal to the area of ​​the projected image of the inorganic particle. The presence of inorganic particles on the surface of the aerosol-forming material is, for example, based on the results of observation of about 10 sheets of the surface of the aerosol-forming material at a magnification of about 500 and a field of view of 100 μm×100 μm after decomposing the aerosol-forming base material. The magnification may be increased as necessary. 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, for example, by a laser diffraction / scattering type particle size distribution measuring device. The powder as a sample is preferably measured by a wet method. For example, Microtrack MT3300III manufactured by Microtrack Bell is used. In the present invention, the average particle size refers to the diameter at 50% of the accumulated volume-based distribution in the range of 0.02 μm to 2000 μm.

[0028] An example of a method for attaching inorganic particles to the surface of an aerosol-forming material is to add 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 more preferably 10 μm or more, since the effect of the present invention is greater. In addition, if the average particle diameter is 100 μm or less, it is easy to maintain the adhesion state on the surface of the aerosol-forming material, and if it is 40 μm or less, it is preferable because it has a sufficient spacer effect and can be sufficiently filled with the filling material.

[0029] The amount of the inorganic powder added is preferably 0.001 parts by mass or more and 10 parts by mass or less relative to 100 parts by mass of the filler. More preferably, it is 0.01 parts by mass or more, so that a sufficient spacer effect can be obtained. A more preferable range is 0.05 parts by mass or more. It is also preferable that it is 5 parts by mass or less, because the spacer effect can be obtained and the filler can be sufficiently filled. A more preferable range is 2 parts by mass or less.

[0030] In addition, 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, the average particle diameter of the inorganic powder to be added is 1 μm or more and 40 μm or less, which has a good effect, and 5 μm or more has an even greater effect of reducing adhesion. The amount of inorganic powder to be added is 0.01 parts by mass or more and 5 parts by mass or less, which has a good effect, and 0.1 parts by mass or more has an even greater effect of reducing adhesion. Regarding this mechanism of action, it is assumed that the inorganic particles exert a polishing effect on the surface when the heating element is detached, scavenge dirt, or reduce dirt due to the small probability of direct contact between the heating element surface and the aerosol forming material during heating due to the spacer effect of the inorganic particles.

[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. The inorganic substances used in the present invention are exemplified above, but 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. In particular, magnesium carbonate, calcium carbonate, silicon oxide, and alumina can be preferably used.

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

[0034] In addition, the aerosol-forming substrate of the present invention needs to be appropriately filled with the filler. If the filling amount is too small, the aerosol generation by heating is insufficient, and the user's smoking experience is insufficient. Conversely, if the filling amount is too large, the filler becomes too clogged, making it difficult for the user to smoke, or the resistance to inserting the heating element becomes too large, causing the electronic cigarette cartridge to break.

[0035] In the present invention, the preferred form of the shape of the filling material is as follows. As an example of one preferred form, FIG. 3 shows a rod- or strip-shaped filling material arranged in the covering member (151) along the longitudinal direction of the aerosol-forming substrate. As another preferred form, FIG. 6 shows a view of the aerosol-forming substrate (110) from one end side, in which the aerosol-forming substrate (110) has a sheet-shaped filling material (112) folded in the covering member (151) along the longitudinal direction of the electronic cigarette cartridge. As another preferred form, FIG. 7 shows a view of the aerosol-forming substrate (110) from one end side, in which the aerosol-forming substrate (110) has a sheet-shaped filling material (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 filling material 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, when the state of the aerosol-forming substrate as viewed from one end is the same as the cross section, this can be adopted.

[0037] For example, it can be obtained by evaluating the filled material and the voids without the filled material using a digital microscope, and can be measured as follows. A digital microscope (Keyence: VHX-2000) was used, and the magnification was 100 times, and the image was projected onto a display. The range of the image to be analyzed was the area where only the filled material and the voids without the filled material appeared. In this case, the observed sample diameter was 7.0 mm, and the width was 3.5 mm and the height was 2.6 mm. In the above range, the image was analyzed using the attached software, and the "extraction mode" was set to "brightness" in the "automatic measurement mode". For the measurement, "standard" was selected, the "extraction parameter" was set to "bright", and the "threshold" was selected so that the filled material and the voids to be observed were separated. The filling rate was determined as the ratio of the filled material to the entire measurement area.

[0038] Thus, the packing rate 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 trying to increase such a packing rate, the packings often tend to adhere to each other, and this 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] Fig. 1 illustrates an example of how an electronic cigarette cartridge is used. When a user uses the electronic cigarette cartridge (100), the electronic cigarette cartridge (100) 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-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 portion (210) of the electronic cigarette body (200).

[0042] The heating element (211) generates heat directly or indirectly by power supplied from a battery (not shown) provided in 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 transferred to the mouthpiece (140) via the support element (300) and the aerosol transfer member (130) described below, and the aromatic components reach the user's mouth when the user inhales from the mouthpiece (140). Hereinafter, for the purpose of explaining the present invention, the aerosol-forming substrate (110) side of the electronic cigarette cartridge is referred to as the upstream side (10), and the mouthpiece side is referred to as the downstream side (20). The upstream side (10) may also be referred to as one end side, and the downstream side (20) may also be referred to as the other end side.

[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 taking the aerosol-forming substrate (110), the support element (300), the transfer member (130), and the mouthpiece (140) from the side where the heating element (211) is inserted, i.e., from the upstream side (10) to the downstream side (20).

[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 a side portion (160) of the support element (300) contacts the packaging member (150) located at 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 an adhesive.

[0046] Additionally, the support element (300) is preferably formed using, for example, silicone, but is not limited to silicone and other materials having excellent heat resistance may be used.

[0047] As shown in FIG. 3, the filler (111) manufactured as the aerosol-forming substrate (110) is preferably shaped like a rod or a strip, and is packed so as to be aligned along the longitudinal direction of the filler (111) during packing. Here, an example is shown in which the filler is packed into a cylindrical wrapping member (151). The wrapping member (151) may be a paper such as tobacco paper shaped into a cylindrical shape. The wrapping 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 how the aerosol-forming substrate (110), transfer member (130), mouthpiece (140) and a support element (300) are arranged adjacent to each other in the order of aerosol-forming substrate (110), support element (300), transfer member (130) and mouthpiece (140) to form a wound rod with a wrapping element (150) such as tobacco paper. At this time, a small amount of adhesive is applied to the side portion (160) of the support element to form an electronic cigarette cartridge (100). Next, a detailed description will be given of an example of use of the electronic cigarette cartridge of the present invention.

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

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

[0051] As shown in Fig. 2, the inside of the electronic cigarette cartridge (100) is provided with an aerosol-forming substrate (110) at one end, and a support element (300) and a transfer member (130) are arranged in this order toward a mouthpiece (140) at the other end. These are then 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 as the aerosol-forming substrate (110) has a shape such as a piece, a strip, or a rod, for example, in which the long side is about 2 to 20 times the short side, the filler (111) is packed so that the longitudinal direction of the shape is aligned with the longitudinal direction of the cartridge during filling. This improves the air flow and makes it easier to inhale. Note that FIG. 3 is a view seen from the end of the electronic cigarette cartridge on the side where the aerosol-forming substrate (110) is located, and is partially see-through so that the filler (111) inside the cartridge can be seen. However, in both cases, the maximum length is preferably about 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 than this, for example, if the filler has a flat shape and a nearly uniform shape, it can be rolled up and packed, making it easy to handle.

[0054] Other preferred forms of the aerosol-forming substrate include those in the form of a sheet that is wrinkled, pleated, gathered or folded.

[0055] Like rod-shaped fillers, fibrous fillers are packed so that the length of the fibers runs along the length of the cartridge, improving the flow of sucked-in air.

[0056] A porous filler is one of the preferred forms because it is porous when filled into the cartridge and 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 cartridge can be shaped like a sheet, such as a square, a rectangle, or a diamond, and the powder, granules, or pellets can be easily filled by dropping them into the cartridge opening. This is also preferable because it is easy to finely adjust the amount of material to be filled into the cartridge (filling amount), and it is easy to adjust the air flow when inhaled depending on the amount of material filled. It can be used more preferably by taking measures to prevent the material from falling out, such as by covering the cartridge opening.

[0058] Block-shaped fillings have good thermal conductivity and are easy to extract aromatic components, so they are one of the preferred forms. The size of the blocks may be made larger to make them easier to store. In that case, the blocks can be reshaped into smaller blocks, rods, granules, or other shapes when filling.

[0059] The effects of the present invention can be obtained by having inorganic particles present on the surface of the packings 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 the packaging member (150) can be rolled up 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 disposed adjacent to the transfer member 130 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 particulate matter. The aroma components that pass through the filter of the mouthpiece 140 are inhaled by the user.

[0063] Comparing the presence or absence of the transfer member (130), the absence of the transfer member (130) provides better ventilation and makes it easier to inhale the generated aromatic components. On the other hand, it is also preferable to add a function of cooling the generated aerosol by inserting the transfer member (130). 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 embodiment since it can stably support the aerosol-forming substrate 110. In addition, the simple configuration is advantageous in terms of production.

[0065] In Fig. 5 (2), 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 material such as a filter or paper that has good breathability and is broken 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 the influence of logistics such as transportation.

[0066] FIG. 5(3) is also preferable to have 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. 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 the influence of logistics such as during transportation. Examples of materials for the lid (170) include filters, paper, and sponges. In addition, 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 at the place 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). It is even more preferable to provide both of them.

[0068] Next, non-tobacco plants 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 the plant can be used, for example, roots (including bulbs, tuberous roots (tubers), 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, udo, radish, and yacon.

[0070] The above-mentioned tubers or the plants listed below contain carbohydrates, and are preferably used as at least a part of the material of the filling 111. For example, starch includes corn starch, potato starch, sweet potato starch, tapioca starch, etc., and there are examples of using them as 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] From plant seeds, tamarind seed gum, guar gum, and locust bean gum can be obtained, from sap, gum arabic and karaya gum can be obtained, from fruits, pectin can be obtained, and from other plants, konjac mannan, which is mainly composed of cellulose and agarose, and soybean polysaccharides can be obtained.Furthermore, they can be used after being modified, such as cationic guar gum.

[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 ground black tea leaves 20 parts by weight of dried and ground liquorice 10 parts by weight of dried and crushed lotus leaves were added to a mixer and dry mixed for 5 minutes.

[0086] The dry mixture is added with Polypropylene glycol 25 parts by weight Glycerin 25 parts by weight Carboxymethylcellulose sodium salt 5 parts by weight Menthol 3 parts by weight Ethanol 3 parts by weight 200 parts by mass of water were added to 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 rack to produce a water-containing sheet. In this embodiment, the water content of the water-containing sheet is approximately 95% when the water content of the slurry is 100%.

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

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

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

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

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

[0093] The sheet was dried and the weight per 100 parts by mass of the sheet was Polypropylene glycol 10 parts by weight Glycerin 20 parts by weight Carboxymethylcellulose sodium salt 2 parts by weight Menthol (50% ethanol solution) 3 parts by weight 50 parts by weight of concentrated cast residue water was added and dried to prepare 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 100 parts by mass of the aerosol-forming material prepared in (Production Example 1) and mixed. Microscopic observation revealed that calcium carbonate particles with diameters of 10 μm to 50 μm were attached. 0.29 g of the aerosol-forming material having calcium carbonate particles on its surface was filled into a paper tube, which is a container member having an inner diameter of 6.9 mm and a height of 12 mm, to prepare an aerosol-forming substrate (110). An electronic cigarette cartridge as shown in FIG. 4 was prepared. A hollow tube having a through hole at its center was used as the support element (300). The diameter of the bottom of the tube was 7 mm, the diameter of the through hole forming the hollow portion was 3 mm, and the material was cellulose acetate. The support element (300) has a function of supporting the aerosol-forming substrate (110) against the force of insertion when the heating element (211) is inserted, and has a through hole as a function of guiding the generated aerosol from the upstream side (10) to the downstream side (20) so that it reaches the mouth of the user. As the transfer member (130), a gathered polymer sheet wrapped in paper to form a cylinder with a bottom diameter of 7 mm and a height of 18 mm was used. The transfer member (130) has a 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 a function of maintaining the temperature of the aerosol at an appropriate level. The mouthpiece (140) used was a filter wrapped in paper to form a cylinder with a bottom diameter of 7 mm and a height of 7 mm. The filling rate was measured and found to be 81%.

[0095] Example 2 1 part by mass of calcium carbonate powder with an average particle size of 15 μm was added to 100 parts by mass of the aerosol-forming material produced in (Production Example 2) and mixed. Microscopic observation showed that calcium carbonate particles with a diameter of 10 μm to 50 μm were attached. 0.29 g of the aerosol-forming material having calcium carbonate 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 to be 83%.

[0096] Example 3 The aerosol-forming material prepared in (Production Example 3) was placed on a desk. Calcium carbonate powder with an average particle size of 15 μm was evenly sprinkled 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 of the sheet 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, 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 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 100 parts by mass of the aerosol forming material prepared in (Production Example 1) and mixed in. Microscopic observation revealed that magnesium carbonate particles with diameters 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, 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 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 were attached. 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 to be 80%.

[0099] Example 6 One part by mass of alumina with an average particle size of 5 μm was added to 100 parts by mass of the aerosol forming material produced in (Production Example 1) and mixed in. Microscopic observation revealed that alumina particles with diameters of 10 μm to 50 μm were attached. 0.29 g of an aerosol-forming material having alumina 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 to be 81%.

[0100] Example 7 One part by mass of alumina having an average particle size of 2 μm was added to 100 parts by mass of the aerosol forming material produced in (Production Example 1) and mixed in. When observed under a microscope, 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, 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 to be 81%.

[0101] Example 8 One part by mass of silicon oxide powder having an average particle size of 0.5 μm was added to 100 parts by mass of the aerosol forming material prepared in (Production Example 1) and mixed in. When observed under a microscope, no silicon oxide 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, 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 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 were attached. An attempt was made to fill 0.29 g of an aerosol-forming material having silicon oxide particles on its surface into a paper tube, which is a packaging member having an inner diameter of 6.9 mm and a height of 12 mm, as a filling material, but due to difficulties in filling, the amount was reduced to 0.23 g. An electronic cigarette cartridge was created in the same manner as in Example 1. The filling rate was measured to be 65%.

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

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

[0105] Comparative Example 3 The aerosol-forming material produced in (Production Example 3) was used as it was as a filler to produce 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 part (210) is 7 mm, which is almost equal to the outer diameter of the electronic cigarette cartridge. The heating element (211) generates heat by power supplied from a battery (not shown) provided in the electronic cigarette body (200), and the temperature reaches approximately 350°C. Then, the built-in control system completes the consumption of one electronic cigarette cartridge after 14 puffs. When the electronic cigarette cartridge of this embodiment is inserted, the electronic cigarette cartridge part that appears from the downstream side of the electronic cigarette body to the outside is approximately 20 mm. Evaluation 1: The electronic cigarette cartridges were packed in a paper box with a long side of 70 mm, a short side of 14 mm, and a height of 45 mm, with the aerosol-forming substrate facing the bottom. The box containing the electronic cigarette cartridges thus prepared was placed in a plastic bag and left in an environment of 40°C for two weeks. After that, it was taken out and left in a normal temperature and humidity environment for one day, and the following evaluation was performed. The fillings were removed from the aerosol-forming substrate, and it was confirmed whether they had solidified. Rank A: The item falls apart when removed with tweezers. Rank B: Can be loosened by pressing with tweezers Rank C: Lumps remain even when pressed with tweezers Rank C items are likely to become difficult to insert into the e-cigarette body due to long-term storage, etc.

[0107] Evaluation 2: In each example and comparative example, the ease and difficulty of making an electronic cigarette cartridge is 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 FIG. 1. The evaluation was performed as follows. Using the electronic cigarette cartridge of Comparative Example 1, 14 puffs were taken per cigarette. The dirt adhering to the heating element after a total of 10, 20, 30, 40, and 50 puffs were wiped off with gauze impregnated with ethanol. The degree of dirt increased as the number of puffs increased.

[0109] In contrast, dirt was collected when 50 electronic cigarette cartridges made in this example were used for smoking, and the degree of dirt was compared and evaluated based on how many cigarettes in Comparative Example 1 the dirt 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, it is possible to make electronic cigarette cartridges that have been through various transportation or storage environments usable without any problems. A further advantage of the present invention is that it reduces contamination of the heating element with 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, it is possible to make electronic cigarette cartridges that have been through various transport or storage environments usable without any problems.

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

[0114] However, since the aerosol-forming base material formed in a sheet shape uses glycerin or the like, it may stick to each other and harden during transportation or storage in a warehouse or store. When it hardens, it becomes difficult for the heating blade to penetrate. This may cause damage to the electronic cigarette cartridge and the heating blade. Therefore, the object of the present invention is to prevent the aerosol-forming base material from sticking to each other and hardening during transportation or storage in a warehouse or store, and to prevent 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.
