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. Materials forming the aerosol-forming material include a carrier for carrying an aerosol former, an aerosol former, and flavor additives 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.) are used as carriers for carrying aerosol formers. , Preferably, it is used in the form of dry pulverization.

Examples of carriers for carrying aerosol formers include gums such as guar gum, xanthan gum, gum arabic and locust bean gum, hydroxypropyl cellulose, carboxymethyl cellulose, hydroxyethyl cellulose, methyl cellulose and ethyl cellulose, in addition to plant parts as described above. Cellulose binders such as starch, organic acids such as alginic acid, polysaccharides such as sodium alginate, conjugate base salts of organic acids such as agar and pectin, and combinations thereof may also be 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. Methyl acid, dimethyl dodecanedioate, dimethyl tetradecanedioate and the like can be used, and 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, relative to the aerosol-forming material.

In addition to the above aerosol former carrier and aerosol former, flavor additives for adding flavor are also preferably used as necessary. Flavoring agents include mint, cocoa, coffee, and tea extracts. Furthermore, when producing an aerosol-forming material using the above materials, in addition to the above, various additives such as water, ethyl alcohol, and thickening agents may be added for preferable production.

For example, in the case of preparing the filling as a sheet, for example, as shown in Japanese Patent Application Publication No. 2010-520764, a sheet containing the tobacco material as described above is prepared, an aerosol former is added to the prepared sheet, or As shown in Table 2017-529848, there is a method of combining an aerosol former, cellulose fibers and tobacco powder to form a slurry and then forming a sheet.

In the case where the packing material is produced in the form of a rod or a strip, the material of the support for carrying the aerosol former as described above, the aerosol former, etc., and water are mixed to form a sheet containing a suitable amount of water. It is molded or cut into a bar 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 substance is difficult to decompose due to the heating.

When the inorganic particles are present on the surface of the filling, the fillings containing the aerosol former do not come into direct contact with each other. By creating such a situation, when the aerosol former oozes out on the surface of the aerosol forming material and increases in abundance under vibration or high temperature conditions to which the electronic cigarette cartridge of the present invention is exposed during transportation or storage. Also in this case, adhesion of the aerosol-forming materials to each other can be prevented.

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

In the present invention, the diameter of the inorganic particles refers to the diameter of a circle obtained by taking an image of the inorganic particles on the surface of the filler with 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 particles is defined as the diameter of the particles.
In addition, the presence of inorganic particles on the surface of the aerosol-forming material can be determined, for example, by decomposing the aerosol-forming base material and observing the surface of the aerosol-forming material at a magnification of about 500 with one field of view of 100 μm×100 μm. according to. Also, the magnification may be increased as necessary. It is also preferable to check with a scanning electron microscope equipped with XMA (X-ray microanalysis) to confirm that it is an inorganic substance.

In addition, in the present invention, for example, a laser diffraction/scattering particle size distribution analyzer is used to measure the particle size of the inorganic powder. A powder as a sample is preferably measured wet. For example, Microtrac MT3300III manufactured by Microtrac Bell is used. In the present invention, the term "average particle size" refers to the cumulative volume-based distribution in the range from 0.02 μm to 2000 μm, and the diameter at 50%.

An example of a method of attaching inorganic particles to the surface of an aerosol-forming material is to add inorganic powder to the aerosol-forming material and mix them. 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 because the effects of the present invention are enhanced. Further, when the average particle diameter is 100 μm or less, the adhesion state on the surface of the aerosol forming material can be easily maintained.

Moreover, the amount of the inorganic powder to be 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, when it is 0.01 parts by mass or more, a sufficient spacer effect can be obtained. A more preferable range is 0.05 parts by mass or more. Further, when the amount is 5 parts by mass or less, the spacer effect can be obtained and the filler can be sufficiently filled, which is preferable. A more preferable range is 2 parts by mass or less.

In the present invention, it has been surprisingly found that when an aerosol-forming material having inorganic particles present on its surface is used to form an aerosol-forming base material, contamination adhering to the heating element after use is reduced. rice field.

In particular, when the average particle size 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, the effect of reducing deposits is further obtained. When the amount of the inorganic powder to be added is 0.01 parts by mass or more and 5 parts by mass or less, a good effect can be obtained, and when it is 0.1 parts by mass or more, the effect of reducing deposits can be further obtained. Regarding this mechanism of action, the inorganic particles exert a polishing effect on the surface when the heating element is attached and detached, or perform scavenging of dirt, or when the heating element surface and the aerosol-forming material are heated, the inorganic particle spacer is formed. It is assumed that the mechanism is that dirt is reduced due to the low probability of direct contact due to the effect.

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 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. can be done. 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 inorganic substances, and include salts with other metals. Furthermore, silicon oxides such as zeolite, colloidal silica and fumed silica can also be used. Magnesium carbonate, calcium carbonate, silicon oxide and alumina are particularly preferred.

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

In addition, the aerosol-forming substrate in the present invention should be appropriately filled with a filler. If the filling amount is too small, the generation of aerosol by heating will be insufficient, and the user's smoking experience will be unsatisfactory. On the other hand, if the fill amount is too high, the fill will clog up, making it difficult for the user to smoke, or the resistance to insertion of the heating element will increase, leading to breakage of the e-cigarette cartridge.

In the present invention, preferred forms of the shape of the filler are as follows. One example of a preferred form is shown in FIG. 3 as being rod-shaped or strip-shaped and arranged in the containment member (151) along the longitudinal direction of the aerosol-forming substrate. In another preferred embodiment, the aerosol-forming substrate (110) is viewed from one end, and the aerosol-forming substrate (110) is in the form of a sheet and extends along the longitudinal direction of the electronic cigarette cartridge. It is shown in FIG. 6 having the filling (112) folded into the member (151). Furthermore, as another preferable form, the aerosol-forming substrate (110) is viewed from one end side, and the aerosol-forming substrate (110) is in the form of a sheet and extends along the longitudinal direction of the electronic cigarette cartridge. It is shown in FIG. 7 having a filler (113) wound into a roll in the member (151).

An appropriate range of the filling amount of the filler can be evaluated by a method of 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 view from one end of the aerosol-forming substrate is equivalent to a cross-section, it can be employed.

For example, using a digital microscope, it can be obtained by evaluating the filling and void portions without the filling, and can be measured as follows. Using a digital microscope (manufactured by Keyence Corporation: VHX-2000), the images were projected on a display at a magnification of 100 times. The range of image analysis is defined as a region in which only the filler and void portions without the filler appear. In this case, the observation sample diameter was 7.0 mm, and the width was 3.5 mm and the length was 2.6 mm. In the above range, the attached software was used for image analysis, and the "extraction mode" was set to "brightness" in the "automatic measurement mode". For measurement, "standard" was selected, "extraction parameter" was set to "bright", and "threshold" was selected so that the observed fillers and voids could be separated. The ratio of the filling to the entire measurement area is taken as the filling rate.

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 trying to increase the filling rate, the fillings often adhere to each other, which makes the present invention useful.

The filling prepared as described above is used as an electronic cigarette cartridge in the electronic cigarette body as follows.

FIG. 1 illustrates a mode of use of an electronic cigarette cartridge. The electronic cigarette cartridge (100) is attached to the electronic cigarette body (200) when the user uses it. The electronic cigarette body (200) is provided with an insertion part (210) for inserting the electronic cigarette cartridge (100).

A heating element (211) is provided in the central part of the bottom in the insert (210), the heating element (211) has a pin-like or blade-like member with a sharp tip, and is used to form an aerosol. It 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 e-cigarette cartridge (100) is inserted into the receptacle (210) of the e-cigarette body (200). inserted.

The heating element (211) directly or indirectly generates heat by power supplied from a battery (not shown) provided in the electronic cigarette body (200). The heat of the heating element (211) warms the aerosol-forming substrate (110) to generate an aerosol containing the fragrance component. Then, the generated aerosol is transferred to the mouthpiece (140) through the support element (300) and the aerosol transfer member (130) described below, and the user inhales from the mouthpiece (140) side, thereby releasing the aromatic component. It will reach the mouth of the user. Hereinafter, 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) for the purpose of describing the present invention. Also, the upstream side (10) may be called one end side, and the downstream side (20) may be called the other end side.

Note that FIG. 1 shows the case where the heating element (211) has one pin-shaped or blade-shaped member, but as an example of another form, the heating element (211) has a pin-shaped or blade-shaped member. One having a plurality of shaped members can be exemplified.

FIG. 2 shows an example of the structure of the electronic cigarette cartridge (100). From the side where the heating element (211) is inserted, i.e. from the upstream side (10) to the downstream side (20), the aerosol-forming substrate (110), the support element (300), the transfer member (130), the mouse. A description will be given with a configuration of pieces (140).

The support element (300) supports the aerosol-forming substrate (110). The support element (300) is positioned adjacent to the aerosol-forming substrate (110) and the sides (160) of said support element (300) are positioned on the perimeter of the electronic cigarette cartridge (100) on the wrapping member (150). come into contact with The sides (160) are fixed to the inner surface of the packaging member (150), for example by means of an adhesive.

Also, the support element (300) can be preferably formed using, for example, silicone, 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 substrate (110) preferably has a shape such as a rod or a strip. It is packed along the longitudinal direction of the shape of . Here, an example is shown in which a cylindrical containing member (151) is filled. As the wrapping member (151), a cylindrical piece of paper such as tobacco paper can be used. Moreover, the packaging member (150) may also serve as the enclosing member (151). This stabilizes the airflow and facilitates the user's inhalation of the fragrance from the aerosol-forming substrate (110).

FIG. 4 shows the aerosol-forming substrate (110), transport member (130), mouthpiece (140) and support element (300) exemplified below, formed as described above, attached to the aerosol-forming substrate (110). , a support element (300), a transfer member (130) and a mouthpiece (140) are shown adjacent in order to form a wound rod with a wrapping member (150) such as tobacco paper. At this time, the sides (160) of the support element are applied with some adhesive, the electronic cigarette cartridge (100).
Next, an example 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 mode of use and appearance of an electronic cigarette cartridge.

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

The interior of the electronic cigarette cartridge (100) is provided with an aerosol-forming substrate (110) at one end and towards a mouthpiece (140) at the other end, as shown for example in FIG. Members (130) are arranged in this order. These are then packaged by a packaging member (150).

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

As shown in FIG. 3, the filling as the aerosol-forming base material (110) has a shape such as a strip shape, a strip shape, a rod shape, etc., in which the long side is about 2 to 20 times as large as the short side. In the case of (1), the longitudinal direction of the shape of the filler (111) is aligned with the longitudinal direction of the cartridge. As a result, the flow of the air current is good and it becomes easy to inhale. Note that FIG. 3 is a view from the end of the electronic cigarette cartridge where the aerosol-forming substrate (110) is located, and is partially transparent so that the filling (111) inside the cartridge can be seen. However, it is preferable that the maximum length of each is about 1 to 20 mm. This is because if the maximum length portion is too large, it may be too large and cumbersome to handle when the cartridge is filled. Of course, in addition to this, for example, if the filling is flat and has a substantially constant shape, it can be rolled and packed, so that it is easy to handle.

As other aerosol-forming substrates, it is also a preferred form to use a sheet formed by wrinkling, pleating, gathering or folding.

As with the rod-shaped filler, the fibrous filler is packed so that the longitudinal direction of the fibers runs along the longitudinal direction of the cartridge, thereby improving the flow of the sucked air.

A porous filler is one of the preferred forms because it is porous when packed in a cartridge and thus improves the flow of air when sucked. In order to make it porous, for example, it can be formed by piercing the dried sheet several times with a plurality of needles, but other methods may be used.

It can be in the form of flakes, squares, rectangles, or flat plates such as diamonds, and powders, granules, and pellets can be easily filled by dropping them into the opening of the cartridge. In addition, it is easy to finely adjust the amount (filling amount) to be packed into the cartridge, and it is easy to adjust the flow of air when sucked by the amount to be packed, which is preferable. It can be used more preferably by taking measures such as covering the opening of the cartridge to prevent it from falling off.

The block-shaped filling has good thermal conductivity and easily extracts the aromatic component. This is one of the preferred forms. Also, the block size may be increased to facilitate storage. In that case, the block can be remolded into small blocks, rods, granules, and the like at the time of filling.

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

The paste-like filling can be squeezed out 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 positioned adjacent to the aerosol-forming substrate (110) and has airflow passages, cutouts, etc. in the center or sides to emanate from the aerosol-forming substrate (110). Aerosol can flow in the direction of the mouthpiece.

A mouthpiece (140) is located at the other end of the electronic cigarette cartridge (100), adjacent to the transfer member (130). Mouthpiece (140) may include a particulate filter, such as a cellulose acetate filter. Aroma components that have passed through the filter of the mouthpiece (140) are inhaled by the user.

Comparing the presence and absence of the transfer member (130), air permeability is better without the transfer member (130), and the generated aromatic component is easier to absorb. On the other hand, it is also preferable to include a transfer member (130) to add the ability to cool the generated aerosol. Instead of adding a transfer member (130), it is also preferred to extend the mouthpiece so that it abuts or abuts 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 may be used, or a crimped polymer sheet wound in the longitudinal direction of the electronic cigarette cartridge may be used.

FIG. 5(1) shows a configuration in which the aerosol-forming substrate (110) and the support element (300) are in contact with each other, which is a preferred configuration because it can stably support the aerosol-forming substrate (110). . In addition, since the structure is simple, there is a great advantage in terms of manufacturing.

In FIG. 5(2), a partition member (160) is provided between the aerosol-forming substrate (110) and the support element (300) so that they are in contact with each other via the partition member (160). The partition member (160) is preferably made of, for example, a filter, paper, or the like which has good air permeability and which 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 effects of physical distribution during transportation.

FIG. 5(3) also preferably has a configuration in which the lid (170) is placed on the side of the aerosol-forming substrate (110) into which the heating element (211) is inserted. This is effective in preventing the aerosol-forming substrate (110) from fading away. Furthermore, there is an effect that the aerosol-forming substrate (110) can be prevented from falling out of the electronic cigarette cartridge due to physical distribution such as transportation. Materials for the lid (170) include filters, paper, and sponge. It is also preferred that if a heating element is inserted, one or more cuts be made in the lid (170) or circular or polygonal guide holes are provided where the heating element is inserted. form.

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

Next, non-tobacco plants used as raw materials will be described. Non-tobacco plants that can also be used in this embodiment are not particularly limited as long as they are plants other than tobacco. Examples of plant parts used include roots (including scales (bulbs), tuberous roots (potatoes), bulbs, etc.), stems, tubers, skins (including stem bark, bark, etc.), leaves, flowers (petals, pistils, stamens, etc.), trunks and branches of trees, and various parts can be used.

These starches are cross-linked to improve acid resistance, heat resistance, shear resistance, etc., esterification and etherification to improve storage stability, accelerate gelatinization, etc., and oxidation to improve transparency, film properties, and storage stability. It is possible by improving it.

To obtain tamarind seed gum, guar gum, and locust bean gum from plant seeds, gum arabic and karaya gum from tree sap, pectin from fruit, and konjac mannan and soybean polysaccharides mainly composed of cellulose and agarose from other plants. can be done. Furthermore, it can be used after modification such as cationized guar gum.
