Embodiments of the present invention will be described below.
As the aerosol forming material used in the present invention, for example, one manufactured as follows is used. Moreover, examples of the material forming the aerosol forming material include a carrier supporting an aerosol former, an aerosol former, and a flavor additive used as necessary.

Various parts of tobacco plants or non-tobacco plants (for example, roots, stems, leaves, flowers, fruits, skins, seeds, tree trunks, tree branches, etc.) can be used as carriers for carrying the aerosol former. It is preferably used in a dry and pulverized form.

In addition to the plant parts mentioned above, carriers for supporting the aerosol former include gums such as guar gum, xanthan gum, gum arabic, and locust bean gum, such as hydroxypropyl cellulose, carboxymethyl cellulose, hydroxyethyl cellulose, methyl cellulose, and ethyl cellulose. Cellulose binders such as starch, organic acids such as alginic acid, polysaccharides such as conjugated base salts of organic acids such as sodium alginate, agar and pectin, and combinations thereof are also used.

Aerosol formers include glycerin, propylene glycol, sorbitol, triethylene glycol, lactic acid, diacetin (glycerin diacetate), triacetin (glycerin triacetate), triethylene glycol diacetate, triethyl citrate, isopropyl myristate, stearin. Although methyl acid, dimethyl dodecanedioate, dimethyl tetradecanedioate, etc. can be used, glycerin and propylene glycol are particularly preferably used. These are used in an amount of 1% by mass or more and 80% by mass or less, particularly preferably 10% by mass or more and 40% by mass or less, based on the aerosol forming material.

In addition to the aerosol former carrier and the aerosol former described above, flavor additives that add flavor as needed are also preferably used. Flavor additives include mint, cocoa, coffee, and tea extracts. Furthermore, when producing an aerosol forming material using the above-mentioned materials, various additives such as water, ethyl alcohol, and a thickening agent may be added in addition to the above for carrying out preferred production.

For example, when making the filler in the form of a sheet, for example, as shown in Japanese Patent Application Publication No. 2010-520764, a sheet containing the above-mentioned tobacco material is made, and an aerosol former is added to the made sheet, or a special As shown in Table 2017-529848, an example is a method of combining an aerosol former, cellulose fibers, and tobacco powder to form a slurry and then forming a sheet.

In addition, when creating the filler in the form of a rod or strip, mix the material of the carrier supporting the aerosol former as described above with the aerosol former and water to form a sheet containing an appropriate amount of moisture. Form or cut into a rod shape 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 particles are difficult to decompose due to the heating.

When the inorganic particles are present on the surface of the filler, the fillers containing the aerosol former are prevented from coming into direct contact with each other. By creating such a situation, when the aerosol former oozes out onto the surface of the aerosol forming material and the amount present increases during the vibration or high temperature conditions that the electronic cigarette cartridge of the present invention is exposed to during transportation or storage. Also, it is possible to prevent the aerosol forming materials from adhering to each other.

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

In the present invention, the diameter of the inorganic particles refers to the diameter equivalent to a circle obtained by taking an image of the inorganic particles on the surface of the filler using an optical microscope or, if necessary, an electron microscope. That is, the diameter of a circle equal to the area of the projected image of the inorganic particle is defined as the diameter of the particle.
In addition, the presence of inorganic particles on the surface of the aerosol forming material can be determined, for example, by observing about 10 images when the aerosol forming base material is decomposed and the surface of the aerosol forming material is 100 μm x 100 μm per field of view at a magnification of about 500. by. Further, the magnification may be increased as necessary. It is also preferable to confirm that it is an inorganic substance using a scanning electron microscope equipped with XMA (X-ray microanalysis).

Further, in the present invention, the particle size of the inorganic powder is measured using, for example, a laser diffraction/scattering type particle size distribution measuring device. The powder as a sample is preferably measured wet. For example, Microtrac MT3300III manufactured by Microtrac Bell Co., Ltd. is used. In the present invention, the term "average particle diameter" refers to the diameter of 50% of the cumulative volume-based distribution in the range from 0.02 μm to 2000 μm.

An example of a method for attaching inorganic particles to the surface of the aerosol forming material is to add and mix inorganic powder to the aerosol forming material. The average particle diameter of the inorganic powder added to the aerosol forming material is preferably 1 μm or more, more preferably 5 μm or more, and preferably 10 μm or more because the effect of the present invention becomes greater. Further, when 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 when it is 40 μm or less, it is preferable because it has a sufficient spacer effect and can be sufficiently filled with the filler.

Further, the amount of the inorganic powder added is preferably 0.001 parts by mass or more and 10 parts by mass or less with respect to 100 parts by mass of the filler. More preferably, if the amount is 0.01 part by mass or more, a sufficient spacer effect can be obtained. A more preferable range is 0.05 part by mass or more. Further, it is preferable that the amount is 5 parts by mass or less, since a spacer effect can be obtained and the filler can be sufficiently filled. A more preferable range is 2 parts by mass or less.

In the present invention, it has been surprisingly found that forming an aerosol-forming base material using an aerosol-forming material on the surface of which inorganic particles are present has the effect of reducing dirt adhering to the heating element after use. Ta.

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 obtained, and when it is 5 μm or more, there is a further effect of reducing deposits. When the amount of the inorganic powder added is 0.01 parts by mass or more and 5 parts by mass or less, a good effect is obtained, and when it is 0.1 parts by mass or more, there is a further effect of reducing deposits. The mechanism of this action is that the inorganic particles exert a polishing effect on the surface when the heating element is attached and detached, scavenging dirt, or that the heating element surface and the aerosol forming material interact with the inorganic particle spacer during heating. The mechanism is assumed to be that dirt is reduced due to the low probability of direct contact.

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, and carbonic acid. Metal carbonates such as magnesium 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 may also be used alone or in combination. I can do it. Although the inorganic substances used in the present invention have been exemplified above, the inorganic particles of the present invention are not limited to the above-mentioned inorganic substances, but 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.

Moreover, natural products including the above-mentioned inorganic substances can also be used. Examples include diatomaceous earth and vermiculite.

Further, in the aerosol-forming base material of the present invention, it is necessary to appropriately fill the material with a filler. If the filling amount is too small, the aerosol generation due to heating will not be sufficient, and the user will experience an unsatisfactory experience when smoking. On the other hand, if the filling amount is too large, the filling will become more clogged, making it difficult for the user to smoke, or increasing the resistance when inserting the heating element, which may damage the electronic cigarette cartridge.

In the present invention, preferred shapes of the filling are as follows. As one example of a preferred form, FIG. 3 shows a rod-like or strip-like shape arranged in the enclosing member (151) along the longitudinal direction of the aerosol-forming base material. In another preferred embodiment, the aerosol-forming base material (110) is a sheet-shaped view of the aerosol-forming base material (110) viewed from one end, and the aerosol-forming base material (110) is sheet-shaped, and the inclusion material is formed along the longitudinal direction of the electronic cigarette cartridge. It is shown in FIG. 6 with the filling (112) folded into the member (151). Furthermore, as another preferable form, the aerosol forming base material (110) is a sheet-like view as viewed from one end side, and the aerosol forming base material (110) is sheet-shaped and the inclusion material is formed along the longitudinal direction of the electronic cigarette cartridge. FIG. 7 shows a member (151) having a filler (113) wound into a roll.

The appropriate range of the filling amount of the filler can be evaluated by calculating the area ratio occupied by the sheet-like aerosol forming material in the cross section of the aerosol forming substrate. In this case, if the state seen from one end of the aerosol forming substrate is equivalent to the cross section, this can be adopted.

For example, it can be determined by using a digital microscope to evaluate the filler and the void portion without the filler, and can be measured as follows. A digital microscope (manufactured by Keyence Corporation: VHX-2000) was used to project the image onto a display at a magnification of 100 times. The range in which the image is analyzed is defined as a region in which only the filler and the void portion without the filler appear. In this case, the diameter of the observation sample was 7.0 mm, and the width was 3.5 mm and the length was 2.6 mm. In the above range, image analysis was performed using the attached software, with the "automatic measurement mode" and the "extraction mode" set to "luminance". For measurement, "Standard" was selected, "Extraction parameter" was set to "Bright", and "Threshold" was selected to separate the observed filling and voids. The filling rate is the ratio of the filling material to the entire measurement area.

Thus, the filling rate is preferably 60% or more and 90% or less. More preferably, it is 65% or more, and still more preferably 70% or more. When attempting to increase such a filling rate, fillers often adhere to each other, making the present invention useful.

The filler prepared as described above is used in an electronic cigarette body as an electronic cigarette cartridge as described below.

FIG. 1 shows an example of how an electronic cigarette cartridge is used. The electronic cigarette cartridge (100) is attached to the electronic cigarette body (200) when used by a user. The electronic cigarette main body (200) is provided with an insertion portion (210) into which the electronic cigarette cartridge (100) is inserted.

A heating element (211) is provided at the center of the bottom inside the insertion part (210), and the heating element (211) has a pin-like or blade-like member with a pointed tip and is used to form an aerosol. is inserted into the substrate (110) and heats the aerosol-forming substrate (110). More specifically, the heating element (211) is placed in the center of the aerosol forming substrate (110) when the electronic cigarette cartridge (100) is inserted into the insertion part (210) of the electronic cigarette body (200). inserted.

The heating element (211) directly or indirectly generates heat using power supplied from a battery (not shown) provided within the electronic cigarette body (200). The heat of the heating element (211) warms the aerosol-forming substrate (110), thereby generating an aerosol containing an aromatic component. The generated aerosol is then transferred to the mouthpiece (140) via a support element (300) and an aerosol transfer member (130), which will be explained below, and the user inhales it from the mouthpiece (140) side, thereby releasing the aromatic components. It will reach the user's mouth. Hereinafter, for the purpose of explaining 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). Further, the upstream side (10) may be referred to as one end side, and the downstream side (20) may be referred to as the other end side.

Although FIG. 1 shows a case where the heating element (211) has one pin-shaped or blade-shaped member, as an example of another form, the heating element (211) has a pin-shaped or blade-shaped member. An example is one having a plurality of shaped members.

FIG. 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 aerosol-forming substrate (110), the support element (300), the transfer member (130), and the mouse. The explanation will be based on the piece configuration (140).

The support element (300) supports the aerosol-forming substrate (110). A support element (300) is positioned adjacent to the aerosol-forming substrate (110), and a side (160) of said support element (300) is connected to a packaging member (150) located at the periphery of the electronic cigarette cartridge (100). come into contact with The side parts (160) are fixed to the inner surface of the packaging member (150), for example by adhesive.

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

As shown in FIG. 3, the filler (111) manufactured as the aerosol forming base material (110) preferably has a shape such as a rod or a strip, and when filling, the filler (111) is It is packed along the longitudinal direction of the shape. Here, an example is shown in which a cylindrical containing member (151) is filled. As the inclusion member (151), it is possible to use paper such as cigarette paper formed into a cylindrical shape. Furthermore, the packaging member (150) may also serve as the inclusion member (151). This stabilizes the airflow and makes it easier for the user to inhale the aromatic components from the aerosol-forming substrate (110).

FIG. 4 shows the aerosol forming base material (110), transfer member (130), mouthpiece (140) formed as described above, and the support element (300) illustrated below. , a support element (300), a transfer member (130) and a mouthpiece (140) are shown adjacent in this order to form a wrapped rod with a wrapping member (150) such as tobacco paper. In this case, the electronic cigarette cartridge (100) is provided with some adhesive on the sides (160) of the support element.
Next, a usage example of the electronic cigarette cartridge of the present invention will be described in detail.

FIGS. 1, 2, 3, and 4 are examples of how an electronic cigarette cartridge is used and its appearance.

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

The interior of the electronic cigarette cartridge (100), as shown for example in FIG. The members (130) are arranged in this order. These are then packaged by a packaging member (150).

The aerosol-forming substrate (110) is a filler for an electronic cigarette cartridge. The aerosol-forming substrate (110) generates an aerosol containing the aromatic components of the plant that is the source of the filling when heated.

As shown in FIG. 3, the filler serving as the aerosol forming base material (110) may have a shape such as a piece, a strip, a rod, etc., in which the long side is about 2 to 20 times larger than the short side. In this case, the cartridge is filled so that the longitudinal direction of the filling material (111) is along the longitudinal direction of the cartridge. This allows for better airflow and easier suction. Note that FIG. 3 is a view of the electronic cigarette cartridge viewed from the end on the side where the aerosol forming base material (110) is located, and is a partially transparent view so that the filler (111) inside the cartridge can be seen. However, in either case, it is preferable that the maximum length portion is approximately 1 to 20 mm. This is because if the maximum length portion is too large, it may be too large and difficult to handle when filling the cartridge. Of course, in addition to this, for example, if the filling is flat and has a substantially constant shape, it can be rolled up and packed, making it easy to handle.

As other aerosol-forming substrates, it is also preferable to use sheets formed by wrinkles, pleats, gathers, or folding.

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

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

Fillings in the form of flakes, squares, rectangles, diamonds, etc., powders, granules, and pellets can be easily filled by dropping them into the cartridge opening. It is also preferable because it is easy to finely adjust the amount to be filled into the cartridge (filling amount), and the flow of air when sucked is easily adjusted depending on the amount to be filled. By taking measures to prevent the cartridge from falling off, such as by covering the opening of the cartridge, it becomes possible to use the cartridge more preferably.

Block-shaped fillings have good thermal conductivity and are easy to extract aromatic components. This is one of the preferred forms. Alternatively, the size of the block may be increased to make it easier to store. In this case, during filling, the block can be reshaped into a small block, rod shape, granule shape, or the like.

The effects of the present invention can be obtained by having inorganic particles present on the surface of the filler having various shapes as exemplified above.

The paste-like filling can be squeezed and filled into the cartridge. Therefore, for example, it is possible to form a cartridge by applying paste to the unfolded packaging member (150) and rolling up the packaging member (150) together.

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 through hole, cutout, etc. in the center or on the side so that the aerosol generated from the aerosol-forming substrate (110) The aerosol can be directed towards the mouthpiece.

A mouthpiece (140) is positioned adjacent the transfer member (130) and at the other end of the electronic cigarette cartridge (100). The mouthpiece (140) may include a filter for removing particulates, such as a cellulose acetate filter. The aroma components that have passed through the filter of the mouthpiece (140) are inhaled by the user.

Comparing the cases with and without the transfer member (130), the one without the transfer member (130) has better air permeability and is easier to absorb the generated aromatic components. On the other hand, it is also preferable to include a transfer member (130) and add a function capable of cooling the generated aerosol. Instead of adding a transfer member (130), it is also preferred to extend the mouthpiece and configure it adjacent to or in contact with the support element (300). This is because the filter used in the mouthpiece can also have a cooling function, and the number of parts can be reduced. As the transfer member (130), a hollow tubular member, a crimped polymer sheet wrapped in the longitudinal direction of the electronic cigarette cartridge, etc. can be used.

FIG. 5(1) shows a configuration in which the aerosol-forming base material (110) and the support element (300) are in contact with each other, which is a preferred form because it can stably support the aerosol-forming base material (110). . Furthermore, since the structure is simple, there are great manufacturing advantages.

In FIG. 5(2), a partition member (160) is provided between the aerosol forming base material (110) and the support element (300) so that they are in contact with each other via the partition member (160). The partition wall member (160) is preferably made of a filter, paper, etc., which has good air permeability, and is breakable when the heating element (211) is inserted. Providing such a partition member is effective in preventing the aerosol forming base material (110) from being moved by the electronic cigarette cartridge due to physical distribution during transportation.

In FIG. 5(3), it is also preferable to have a lid (170) on the side of the aerosol-forming substrate (110) into which the heating element (211) is inserted. This is effective in preventing the aroma from the aerosol-forming substrate (110) from dissipating. Furthermore, it is possible to prevent the aerosol-forming base material (110) from falling out of the electronic cigarette cartridge due to physical distribution during transportation or the like. Examples of the material for the lid (170) include a filter, paper, and sponge. In addition, when the heating element is inserted, it is also preferable to make one or more cuts in the lid (170) or to provide a circular or polygonal guide hole at the place where the heating element is inserted. It is a form.

In particular, when a granular 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 explained. The non-tobacco plants that can also be used in this embodiment are not particularly limited as long as they are plants other than tobacco. Parts of plants used include, for example, roots (including scales, tubers, bulbs, etc.), stems, tubers, skins (including stem bark, bark, etc.), leaves, flowers (petals, Various parts can be used, including pistils, stamens, etc.), tree trunks, and branches.

For example, starch includes corn starch (corn), potato starch (potato), sweet potato starch (sweet potato), tapioca starch (tapioca), etc., and there are examples of their use as thickeners, stabilizers, etc. These starches improve acid resistance, heat resistance, and shear resistance through crosslinking, improve storage stability through esterification and etherification, and promote gelatinization, and improve transparency, film properties, and storage stability through oxidation. This is possible by making improvements.

Tamarind seed gum, guar gum, and locust bean gum are obtained from plant seeds, gum arabic and gum karaya are obtained from tree sap, pectin is obtained from fruits, and konjac mannan and soybean polysaccharides, which are mainly composed of cellulose and agarose, are obtained from other plants. I can do it. Furthermore, it can be used after being modified like cationized guar gum.
