Description

The present invention relates to an electronic cigarette cartridge and a filler for use in an electronic cigarette.

In recent years, in order to keep up with the trend towards smoking cessation, electronic cigarette products that allow users to enjoy tobacco without using a flame by heating a cartridge containing tobacco components and inhaling the vaporized tobacco components have begun to 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 so 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).

Patent No. 6000451

In addition, the aerosol-forming substrate of the present invention needs to 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 is not generated by heating, and the resistance when the user inhales when smoking is too low, resulting in an unsatisfactory smoking experience. Furthermore, if the filling rate is preferably 65% or more, the smoking experience tends to be improved. Conversely, if the filling rate is more than 90% and the filling amount is too large, the filler becomes clogged to a large extent, making it difficult for the user to smoke, increasing the resistance when inserting the heating element, or damaging the electronic cigarette cartridge.

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 filler surrounded by a packaging member.

The invention described in claim 2 is the invention described in claim 1, in which the filler has at least one of the following shapes: rod-like, rectangular, and fibrous.

The invention described in claim 3 is the invention described in claim 1, in which 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.

The invention described in claim 4 is the invention described in claim 1, in which the filling is in a sheet shape and has at least one of the following shapes: wrinkled, pleated, and gathered.

The invention described in claim 5 is the invention described in claim 1, in which the filling material 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-type shape wound inside the electronic cigarette cartridge.

The invention described in claim 6 is the invention described in any one of claims 1 to 5, in which the wrapping member or the packaging member has a lid on the heating element insertion side.

The invention described in claim 7 is the invention described in claim 1, in which the filling has an aerosol former that generates an aerosol by heating, and has a carrier that supports the aerosol former.

The invention described in claim 8 is the invention described in claim 7, in which the carrier is selected from at least one of rubber, cellulose binder, and polysaccharide, and the filler has inorganic particles.

The invention described in claim 9 is the invention described in claim 8, in which the inorganic particles contain diatomaceous earth.

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.

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.

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.) are used, preferably in a dried and crushed form.

In addition to the plant parts mentioned above, the carriers that carry the aerosol formers 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, sodium alginate, agar, and conjugate base salts of organic acids such as pectin, and combinations thereof.

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 dodecanedione, dimethyl tetradecanedione, 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 relative to the aerosol forming material, and it is particularly preferred that they be used in an amount of 10% by mass or more and 40% by mass or less.

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 using the above-mentioned materials to manufacture an aerosol-forming material, various additives such as water, ethyl alcohol, and thickeners may be added in addition to the above to carry out a preferred manufacture.

For example, when preparing the filling material as a sheet, as described in JP-T-2010-520764, a sheet containing the above-mentioned tobacco material is prepared and an aerosol former is added to the prepared sheet, or as described in JP-T-2017-529848, an aerosol former is combined with cellulose fiber and tobacco powder to form a slurry, which is then formed into a sheet.

When making the filler into a rod or strip shape, the material for the carrier that holds the aerosol former as described above is mixed with the aerosol former and water, and the resulting sheet is appropriately moistened and then molded or cut into the desired rod or strip shape.

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, the inorganic substances are less likely to decompose due to the heating.

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 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 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.

To achieve 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 the diameter is 5 μm or more, it is preferable because it functions more effectively as a spacer between the fillers. Furthermore, if the diameter is 10 μm or more, it is even more preferable. Furthermore, if the diameter is 50 μm or less, it is preferable because it has a sufficient spacer effect and can be sufficiently filled with the fillers.

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 observing about 10 sheets of the aerosol-forming material surface 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 the presence of inorganic particles using a scanning electron microscope equipped with XMA (X-ray microanalysis) in order to confirm that the particles are inorganic.

In the present invention, the particle size of inorganic powders is measured using, for example, a laser diffraction/scattering type particle size distribution measuring device. Powder samples are preferably measured wet. For example, Microtrack MT3300III manufactured by Microtrack Bell is used. In the present invention, the average particle size refers to the diameter at which the volume-based distribution is accumulated to 50% in the range of 0.02 μm to 2000 μm.

One 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 size of 1 μm or more, more preferably 5 μm or more, and preferably 10 μm or more, since this enhances the effect of the present invention. In addition, an average particle size of 100 μm or less makes it easier to maintain the adhesion state to the surface of the aerosol-forming material, and a particle size of 40 μm or less is preferable, since it has a sufficient spacer effect and can be sufficiently filled with the filler.

The amount of the inorganic powder added is preferably 0.001 parts by mass or more and 10 parts by mass or less per 100 parts by mass of the filler. More preferably, it is 0.01 parts by mass or more, which allows a sufficient spacer effect to be obtained. A more preferred range is 0.05 parts by mass or more. It is also preferable that it is 5 parts by mass or less, since it allows the spacer effect to be obtained and the filler to be sufficiently filled. A more preferred range is 2 parts by mass or less.

Furthermore, in the present invention, it has been found that forming an aerosol-forming substrate using an aerosol-forming material having inorganic particles present on the surface has the surprising effect of reducing dirt adhering to the heating element after use.

In particular, the average particle size of the inorganic powder to be added is 1 μm or more and 40 μm or less for good effect, and 5 μm or more for even more effective in reducing adhesions. The amount of inorganic powder to be added is 0.01 parts by mass or more and 5 parts by mass or less for good effect, and 0.1 parts by mass or more for even more effective in reducing adhesions. 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 and 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.

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 above are examples of inorganic substances that can be used in the present invention, 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.

It is also possible to use natural materials that contain the above-mentioned inorganic substances. Examples include diatomaceous earth and vermiculite.

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 generated by heating is insufficient, and the user will experience an unsatisfactory smoking experience. 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.

In the present invention, the preferred form of the shape of the filling is as follows. As an example of a preferred form, FIG. 3 shows a rod-shaped or strip-shaped filling arranged in the wrapping 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) is in the form of a sheet and has a filling (112) folded in the wrapping 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) is in the form of a sheet and has a filling (113) wound in the wrapping member (151) along the longitudinal direction of the electronic cigarette cartridge in the form of a roll.

The appropriate range of the amount of 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, if the state of the aerosol-forming substrate as viewed from one end is the same as the cross section, this can be used.

For example, it can be determined by using a digital microscope to evaluate the filled material and the voids without filled material, and can be measured as follows. A digital microscope (Keyence: VHX-2000) was used, and the image was projected onto a display at a magnification of 100x. The range of image analysis was the area in which only the filled material and the voids without filled material appeared. In this case, the observed sample had a diameter of 7.0 mm, and the dimensions were 3.5 mm wide and 2.6 mm high. Within the above range, image analysis was performed using the attached software, with the "extraction mode" set to "brightness" in the "automatic measurement mode." For measurement, "standard" was selected, the "extraction parameter" was set to "bright," and the "threshold" was selected so that the observed filled material and voids were separated. The filling rate was determined as the ratio of the filled material to the entire measurement area.

As such, the filling 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 filling rate, the fillers often end up adhering to each other, which is why the present invention is useful.

The filler prepared as described above is used in the electronic cigarette body as an electronic cigarette cartridge as follows:

Figure 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 the electronic cigarette body (200). The electronic cigarette body (200) is provided with an insertion portion (210) for inserting the electronic cigarette cartridge (100).

A heating element (211) is provided in the center of the bottom of the insertion portion (210). The heating element (211) has a pin-shaped or blade-shaped member with a sharp 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).

The heating element (211) generates heat directly or indirectly by power supplied from a battery (not shown) installed 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 then 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.

Note that FIG. 1 illustrates a case where the heating element (211) has one pin-shaped or blade-shaped member, but an example of another form is a heating element (211) having multiple pin-shaped or blade-shaped members.

Figure 2 shows an example of the structure of an electronic cigarette cartridge (100). From the side where the heating element (211) is inserted, that is, from the upstream side (10) to the downstream side (20), the structure is described as taking the aerosol-forming substrate (110), the support element (300), the transfer member (130), and the mouthpiece (140).

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 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 adhesive.

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

As shown in FIG. 3, the filler (111) manufactured as the aerosol-forming substrate (110) is preferably shaped, for example, in a rod or strip shape, and is packed so as to align the filler (111) along the longitudinal direction of its shape when filling. Here, an example is shown in which the filler is filled into a cylindrically shaped wrapping member (151). The wrapping member (151) may be a paper such as tobacco paper shaped into a cylindrical shape. 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).

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

Figures 1, 2, 3 and 4 are examples of the usage and appearance of an electronic cigarette cartridge.

The electronic cigarette cartridge (100) has an external appearance of, for example, a rod or cylinder shape, as shown in FIG. 2.

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

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 from the plant that is the source of the filler.

When the filler as the aerosol-forming substrate (110) is, for example, in the shape of a piece, a strip, or a rod, in which the long side is about 2 to 20 times the short side, as shown in FIG. 3, the filler (111) is packed so that the longitudinal direction of the shape is aligned with the longitudinal direction of the cartridge when filling. This improves the air flow and makes it easier to inhale. Note that FIG. 3 is a view 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, it is preferable that the maximum length is 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 is flat and has a nearly uniform shape, it can be rolled up and packed, making it easy to handle.

Other preferred forms of aerosol-forming substrates include sheets formed by crinkling, pleating, gathering or folding.

As with rod-shaped fillers, the fibrous filler improves the flow of sucked-in air by packing the fibers so that their length runs along the length of the cartridge.

A porous filler is one of the preferred forms, because when it is packed into the cartridge, it is porous, which improves the flow of air when inhaled. To make it porous, for example, it can be formed by piercing the dried sheet several times with multiple needles, but other methods are also possible.

The cartridge can be flat, flaky, square, rectangular, or diamond shaped, and the powder, granule, or pellet filler can be easily dropped into the cartridge opening. This is also preferable because it is easy to finely adjust the amount filled into the cartridge (filling amount), and the air flow when inhaled can be easily adjusted depending on the amount filled. It can be used even more preferably by taking measures to prevent the cartridge opening from falling out, such as by putting a lid on it.

Block-shaped fillings have good thermal conductivity and are easy to extract aromatic components. This is one of the preferred forms. The size of the blocks can also be increased to make them easier to store. In that case, when filling, the blocks can be reshaped into smaller blocks, rods, granules, or other shapes.

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

The paste-like filling material can be squeezed out and filled into the cartridge. For this reason, for example, it is possible to apply paste to the packaging member (150) in an unfolded state and then roll up the packaging member (150) to form a cartridge.

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

The mouthpiece (140) is disposed adjacent to the transport 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 fine particles. The aroma components that pass through the filter of the mouthpiece (140) are inhaled by the user.

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 to cool 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, and the number of parts can be reduced. As the transfer member (130), a hollow tubular member or a crimped polymer sheet wound in the longitudinal direction of the electronic cigarette cartridge can be used.

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

In FIG. 5 (2), a partition member (160) is provided between the aerosol-forming substrate (110) and the support element (300), and they are in contact with each other via the partition member (160). The partition member (160) is preferably made of, for example, a filter or paper that has good breathability, 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 the influence of logistics such as during transportation.

In FIG. 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 the influence of logistics such as during transportation. Examples of materials for the lid (170) include filters, paper, sponge, etc. In addition, when a heating element is inserted, it is also preferred to make 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.

In particular, when a particulate material such as powder, granules, flakes, or pellets is used as the aerosol-forming substrate (110), it is preferable to provide a partition member (160) or a lid (170). Furthermore, it is even more preferable to provide both.

Next, the non-tobacco plants used as raw materials will be described. There are no particular limitations on the non-tobacco plants that can be used in this embodiment, so long as they are plants other than tobacco. Various parts of the plant can be used, such as roots (including bulbs, tubers (tubers), bulbs, etc.), stems, tubers, bark (including stem bark, bark, etc.), leaves, flowers (including petals, pistils, stamens, etc.), tree trunks and branches, etc.

Bulbs include onion, red spider lily, tulip, hyacinth, garlic, shallot, and lily. Corms include crocus, gladiolus, freesia, iris, taro, and konjac. Tubers include konjac, cyclamen, anemone, begonia, Chinese chive, potato, and apios. Roots include canna, lotus (lotus root), and ginger. Root tubers include dahlia, sweet potato, cassava, and Jerusalem artichoke. Rhizomes include Dioscorea genus (yams such as Chinese yam, wild yam, and Chinese yam), and others include turnip, burdock, carrot, radish, and kudzu. Stems include asparagus, bamboo shoots, udo, radish, and yacon.

The above-mentioned tubers and the plants listed below contain carbohydrates, and are preferably used as at least a part of the material for 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, and shear resistance, esterified and etherified to improve storage stability and promote gelatinization, and oxidized to improve transparency, film properties, and storage stability.

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 soy polysaccharides, mainly composed of cellulose and agarose, can be obtained from other plants. Furthermore, guar gum can be used after modification, such as cationic guar gum.

Seaweed can produce carrageenan, classified into three types: kappa carrageenan, iota carrageenan, and lambda carrageenan, as well as agar and alginic acid, which are also used as salts such as carrageenan metal salts and sodium alginate.

The present invention will be described in detail below.
(Production Example 1)
100 parts by mass of dried and ground black tea leaves, 20 parts by mass of dried and ground liquorice (legume family), and 10 parts by mass of dried and ground lotus leaves were put into a mixer and dry-mixed for 5 minutes.

The dry mixture is added with
25 parts by weight of polypropylene glycol, 25 parts by weight of glycerin, 5 parts by weight of sodium carboxymethylcellulose, 3 parts by weight of menthol, 3 parts by weight of ethanol, and 200 parts by weight of water were charged into the mixer and wet-mixed for 15 minutes.

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 create a water-containing sheet. In this embodiment, the water-containing sheet had a water content of approximately 95% if the water content of the slurry was 100%.

Then, the water-containing sheet was passed three times through a press roll with a predetermined clearance to form it, 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 roll five more times.

Furthermore, the formed water-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 water 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 piece having a length of 12 mm, a width of 1.5 mm and a thickness of 0.5 mm to prepare an aerosol-forming material.

In (Manufacturing 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.

(Production Example 3)
50 parts by mass of wood fiber, 50 parts by mass of dried black tea leaves, and 5,000 parts by mass or more of water were mixed to prepare a slurry.

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.

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 Cast The remaining concentrated water (50 parts by weight) 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.

Example 1
One part by mass of calcium carbonate powder having 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 having 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, which is a packaging member having an inner diameter of 6.9 mm and a height of 12 mm, to form 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 insertion force 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 user's mouth. 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 mouth of the user, 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%.

(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.

The following evaluations were performed on the electronic cigarette cartridge obtained as described above. 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) is heated by power supplied from a battery (not shown) installed in the electronic cigarette body (200), and reaches approximately 350°C. Then, the built-in control system completes the consumption of one electronic cigarette cartridge after 14 puffs. Note that when the electronic cigarette cartridge of this embodiment is inserted, the electronic cigarette cartridge portion that appears from the downstream side of the electronic cigarette body to the outside is approximately 20 mm.
Evaluation 1: The electronic cigarette cartridge was prepared and 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 cartridge 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 filling was removed from the aerosol-forming substrate, and it was confirmed whether they had solidified.
Rank A: Those that fall apart when removed with tweezers Rank B: Those that can be pressed apart with tweezers Rank C: Those that remain in clumps even when pressed with tweezers Rank C items are likely to become difficult to insert into the electronic cigarette body after long-term storage, etc.

Evaluation 2: This compares the ease and difficulty of creating electronic cigarette cartridges in each example and comparative example. If there are no particular comments in each example, this means that there are no problems.

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 performed 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 with gauze soaked in ethanol. The degree of dirt increased as the number of puffs increased.

In contrast, dirt was collected when 50 electronic cigarette cartridges made in this example were used, and the degree of dirt was compared and evaluated based on how many cigarettes in Comparative Example 1 it corresponded to.

The evaluation results are summarized in Table 1.

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.

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 the electronic cigarette cartridge usable without any problems even if it has been subjected to various transport or storage environments.

Another advantage of the present invention is that it reduces contamination of the heating element caused by use, which can extend the frequency of cleaning and the lifespan of the electronic cigarette body.

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

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 configuration described in the claims, and these modifications are also within the scope of the present invention.
