Embodiments of the present invention will be described below with reference to the attached drawings. The present invention is not limited to the following embodiments. In addition, in the description of the drawings, the same elements are given the same reference numerals, and redundant description will be omitted. Further, the dimensional ratios in the drawings are merely examples, and the invention is not limited thereto. Further, for convenience of explanation, some parts may be exaggerated.

The sheet-like filling material used in this example is produced, for example, as follows. Examples of materials for forming the aerosol forming material include a carrier supporting 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.) can be used as carriers for carrying the aerosol former. It is preferably used in a dry and pulverized form.

In addition to the above-mentioned plant parts, examples of carriers or binders 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 Cellulose binders such as ethylcellulose, polysaccharides such as glucomannan, starch, organic acids such as alginic acid, 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 preferably used in an amount of 1% by mass or more and 80% by mass or less based on the electronic cigarette filler. More preferably, the content is 10% by mass or more and 40% by mass or less.

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 materials, various additives such as water, ethyl alcohol, and thickeners may be added in addition to the above.

For example, when making the filler in the form of a sheet, it is possible to create a sheet containing the tobacco material as described above and add an aerosol former to the created sheet, or by combining the aerosol former, cellulose fibers, and tobacco powder. One method is to make a slurry and then make a sheet.

In this example, cellulose fibers, a binder, black tea, an aerosol former, and a flavor additive are made into a slurry, which is cast onto a metal plate, and the cast slurry is dried to produce a sheet. The thickness was set to 0.2 mm. The sheet used in the present invention preferably has a thickness of 0.1 mm or more and 0.5 mm or less.

The method for producing the aerosol-forming base material using a sheet-like member having cuts as a filler used in this example includes the following.

As an example of one method, a sheet having predetermined cuts is processed into a desired shape to form a sheet-like member having cuts, and then a packaging member ( 151), etc. As another method, as shown in FIGS. 2 and 5, after processing the prepared sheet into a desired shape, incisions are formed to form a sheet-like member having incisions, and then a packaging sheet (150) etc. is used as a filling material. One example is the method of filling. Further, as an example of a possible method, after processing the created sheet into a desired shape and shaping it into the shape for filling, forming notches and filling the packaging sheet (150) etc. as a sheet-like filling material having notches. One method is to do so. Further, as an example of a possible method, after processing the created sheet into a desired shape and filling it into a packaging sheet (150) etc. as a filler, a notch is formed, and a filler in the form of a sheet member having a notch is formed. One method is to do so.

Further, although the sheets have notches, they are connected by a portion without a notch.

Preferably, the process of creating the sheet, forming the cuts, shaping the sheet into a desired shape, and filling the sheet are performed continuously, or two or more of the steps are performed simultaneously. is also a preferred method. This is because such a process has good production efficiency.

Examples of means used to form the cuts include a cutter blade, razor blade, rotary cutter, etc., and a method of arranging these in parallel to form the required number of cuts at once is a preferred form. There is one.

Further, the interval W between the notches (shown in FIGS. 9, 13, and 14) is preferably larger than the thickness of the sheet, for example, preferably 0.5 mm or more and 10 mm or less. More preferably, when the width is 1 mm or more, the region divided by the notch is stable without tearing, and if it is 5 mm or less, the region divided by the notch prevents the filling from being broken when the heating element shown in FIG. 1 is inserted. can be prevented from moving in the insertion direction, and the effects of the present invention can be further exhibited.

Regarding the length of the cut formed in the sheet, for example, referring to FIG. 9, if the length is 20% or more of the total length of the sheet in the Y direction, then the length of the cut formed in the sheet will be 20% or more with respect to the insertion of the heating element (211) shown in FIG. The effect of the present invention can be exhibited more effectively when the ratio is 50% or more, and it is even more effective when the ratio is 50% or more. Moreover, if it is 90% or less, it is possible to prevent the filling from moving in the insertion direction with respect to insertion of the heating element (211). When the content is 90% or less, even when the electronic cigarette cartridge is removed from the electronic cigarette body after use, it is sufficiently effective in preventing part of the filling material from falling off after use.

Although the interval and length of the notches made in the sheet have been described, the interval W and length of each individual notch may be changed in one sheet.

In addition, in this embodiment, if the filling and the packaging member (151) shown in FIGS. 3, 4, and 10 to 12 are fixed, even when the electronic cigarette cartridge is taken out from the electronic cigarette body after use, , is effective in preventing the filling from falling off after use. This is because after the electronic cigarette cartridge is used, the filling deteriorates due to heating, and the filling may stick to the heating element (211) shown in FIG. 1, which may lead to the filling falling off after use. If this kind of falling off occurs, the inside of the electronic cigarette body becomes dirty and the frequency of cleaning increases, causing problems in usability.

FIG. 1 illustrates a usage pattern of an electronic cigarette cartridge (100). 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, when the electronic cigarette cartridge (100) is inserted into the insertion part (210) of the electronic cigarette body (200), the heating element (211) is heated to the center of the aerosol-forming substrate (110). inserted.

The heating element (211) generates heat directly or indirectly using electric power supplied from a battery (not shown) provided within the electronic cigarette body (200). The aerosol-forming substrate (110) is warmed by the heat of the heating element (211), thereby generating an aerosol containing an aromatic component. The generated aerosol is then transferred to the mouthpiece (140) via the support element (300) and transfer member (130), which will be explained below, and the user inhales from the mouthpiece (140) side, so that the aromatic components are transferred to the user. It will reach the inside of the mouth. Hereinafter, for the purpose of explaining the present embodiment, the aerosol forming base material (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) is sometimes referred to as one end side, and the downstream side (20) is sometimes 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) shown in FIG. ), and includes a mouthpiece (140), which has a rod-like or cylindrical appearance, for example.

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

An aerosol-forming substrate (110) is disposed at the upstream (10) end of the electronic cigarette cartridge (100), and a mouthpiece (140) is disposed at the downstream (20) end. The direction connecting the arrangement position of the aerosol-forming substrate (110) and the arrangement position of the mouthpiece (140), that is, the aerosol-forming substrate (110), the support element (300), the transfer member (130), and the mouthpiece (140). ) is defined as the longitudinal direction of the electronic cigarette cartridge (100).

The aerosol-forming substrate (110), support element (300), transfer member (130) and mouthpiece (140) are packaged by a packaging sheet (150). Note that the longitudinal direction of the electronic cigarette cartridge (100) and the longitudinal direction of the aerosol forming substrate (110) are, for example, parallel. Further, the longitudinal direction of the electronic cigarette cartridge (100) and the longitudinal direction of the aerosol forming substrate (110) are parallel to the Y-axis direction in relation to the electronic cigarette filler shown in FIGS. 6B and 6C, for example. .

The aerosol-forming substrate (110) contains a filler for electronic cigarettes, and when heated, for example, generates an aerosol containing aromatic components of plants that are materials for the filler for electronic cigarettes.

The support element (300) is made of silicone, for example, and supports the aerosol-forming substrate (110). The sides of the support element (300) are fixed to the inner surface of the packaging sheet (150), for example with adhesive. Note that the support element (300) is not limited to silicone, and may be formed using other materials with excellent heat resistance.

The illustrated support element (300) is provided with an air flow hole in the center. The aerosol generated in the aerosol-forming substrate (110) passes through the airflow holes and flows toward the mouthpiece (140). Note that the support element (300) may be provided with airflow holes, cutouts, etc. on the side.

The transfer member (130) is configured using a hollow tubular member or a polymer sheet wound in the longitudinal direction of the electronic cigarette cartridge (100), and cools the aerosol flowing toward the mouthpiece (140), for example. do.

The mouthpiece (140) is formed using paper or the like, for example. It may also include a cellulose acetate filter or the like to remove particulates. The aromatic components that have passed through the filter of the mouthpiece (140) are inhaled by the user.

Note that the transfer member (130) can be omitted and the number of components can be reduced. When the transfer member (130) is omitted, air permeability is improved and the generated aerosol flows more easily to the downstream side (20), making it easier for the user to inhale the aromatic components.

As an example, the transfer member (130) is omitted, and the mouthpiece (140), which is elongated in the longitudinal direction of the electronic cigarette cartridge (100), is arranged adjacent to the support element (300). In that case, for example, it is possible to make the cellulose acetate filter also have a cooling function.

Furthermore, the packaging sheet (150) may also be configured to serve as a packaging member for wrapping the electronic cigarette filler. The aerosol airflow is stabilized, making it easier for the user to inhale the aromatic ingredients.

As shown in FIG. 3, the filler (111) manufactured as the aerosol-forming base material (110) is wrapped in a sheet around the approximately central axis (112) of the cross section of the electronic cigarette cartridge. An example is shown in which a scroll is created by rolling the material and used as a filling material. Here, an example is shown in which a cylindrical packaging member (151) is filled. As the packaging member (151), it is possible to use paper such as cigarette paper formed into a cylindrical shape. Furthermore, the packaging sheet (150) may also serve as the packaging member (151). This stabilizes the airflow and makes it easier for the user to inhale the fragrance from the aerosol-forming substrate (110).

FIGS. 4(1) to 4(4) are diagrams illustrating examples of the form in which sheets are used as fillers. Each of FIGS. 4A and 4B are views of the aerosol forming substrate (110) from the upstream side (10). Alternatively, the cross section may be shown in a plane perpendicular to the longitudinal centerline of the electronic cigarette cartridge.

FIG. 4(1) shows an example in which a sheet is rolled up like a nori seaweed roll to form a roll, which is then filled into a packaging member (151) to form a filling material (111).

FIG. 4(2) shows a sheet that is folded to a size that is approximately equal to or slightly smaller than the inner diameter of the packaging member (151), with the folding line oriented in the longitudinal direction of the electronic cigarette cartridge. A packaging member (151) is filled with the filling material (111) as shown in FIG.

In FIG. 4(3), the sheet is folded to a size larger than the inner diameter of the packaging member (151), and then the entire sheet is folded or curved at approximately the center and filled. The electronic cigarette cartridge is filled so that the direction of the folding line is along the longitudinal direction of the electronic cigarette cartridge.

In FIG. 4(4), the sheet is folded to a width smaller than the inner diameter of the packaging member (151), and includes, for example, a so-called crimping process, but the direction of the folding line is aligned with the longitudinal direction of the electronic cigarette cartridge. It is filled to match. Of course, the crimped sheet may be in the form of a scroll, a folded sheet, a folded sheet, or a curved sheet, as shown in FIGS. 4(1) to (3) above. It is also preferable to use a filling material as shown in FIGS. 4(1) to 4(3) above.

FIG. 5 is a schematic flowchart showing a method for manufacturing an electronic cigarette filler according to an example. With reference to FIG. 5, a method for manufacturing an electronic cigarette filler and the like according to an example will be described.

In the method for manufacturing an electronic cigarette filler according to the embodiment, materials are prepared in step S101. In step S102, the prepared materials are mixed to form a non-tobacco plant composition. Then, in step S103, the non-tobacco plant composition formed in step S102 is processed to obtain a filler for electronic cigarettes.

Note that an electronic cigarette cartridge can be manufactured using the electronic cigarette filler obtained in step S103. This process is referred to as step S104.

The step S101 of preparing materials includes three steps: step S101a, step S101b, and step S101c. Step S101a is a process of drying and pulverizing non-tobacco plants etc. that are the source of the fragrance, step S101b is a process of dissolving menthol, and step S101c is a process of preparing materials such as an aerosol former. The order in which steps S101a to S101c are performed does not matter. They can also be performed in parallel.

The process of drying and crushing non-tobacco plants, etc. in step S101a will be explained. After drying the non-tobacco plants, they are ground. Drying is performed, for example, by heating in an oven. The drying temperature is preferably 60°C or higher and 80°C or lower. In this temperature range, it is easy to reach the desired moisture content while avoiding dissipation (sublimation) of the required aroma components. When the temperature is 65°C or higher, it is easier to reach the desired moisture content. When the temperature is 75° C. or lower, it is possible to further prevent the necessary aroma components from dissipating.

The pulverization is carried out using, for example, an agitation type pulverizer. The parts of the non-tobacco plant used as raw materials (leaves, seeds, dried fruits, stems, bark, roots, etc.) are processed into a desired pulverized product to constitute a non-tobacco plant composition. At that time, it is preferable to adjust the amount of water so that it is convenient for absorbing or supporting components such as the aerosol former and water prepared in step S101c, for example.

In addition, in the case of non-tobacco plants etc. that do not require drying, they can be crushed without drying. Further, if the raw materials can be used as they are and do not require drying or pulverization, step S101a can be omitted and the raw materials can be fed into the mixing step of step S102.

The moisture content of the non-tobacco plants after drying and pulverization is preferably 5% by mass or less. By doing so, it becomes easier to form a slurry in the mixing step of step S102. More preferably, it is 3% by mass or less. Further, the moisture content of the non-tobacco plant etc. after drying and pulverization is preferably 0.1% by mass or more. It can maintain good compatibility with water, etc.

Note that the drying and pulverizing process in step S101a may include a sieving process of sieving the dried and pulverized product. By introducing the sieving process, non-tobacco plants etc. can be input to the mixing process in step S102 with a desired particle size.

In the example, black tea leaves were dried in an oven at 70° C., then ground using an agitating grinder, and passed through an 80-mesh sieve. The water content was 2% by mass.

Next, in step S101b, which describes the step of dissolving menthol in step S101b, menthol, lower alcohol, and water-insoluble crosslinked polymer are weighed and mixed to dissolve menthol. After dissolving menthol in the lower alcohol, it is preferable to add and mix the water-insoluble crosslinked polymer. When menthol, lower alcohol, and water-insoluble crosslinked polymer are mixed, the effect of suppressing menthol dissipation can be obtained.

Menthol is not limited to those obtained from natural products, and may be synthetic. You can also use mint, mint, peppermint oil, and other materials containing menthol.

The lower alcohol is a solvent that dissolves menthol, and ethyl alcohol is particularly preferably used.

The water-insoluble crosslinked polymer is intended to be a non-crosslinked polymer that is soluble in water and crosslinked so that it becomes insoluble in water and swells. Of course, it is preferable that it does not dissolve in lower alcohols but swells, and such a substance is selected. Such a water-insoluble crosslinked polymer has a hydrophilic part and a hydrophobic part, and the hydrophilic part contributes to swelling, and the hydrophilic part orients to menthol, thereby suppressing the dissipation of menthol. Conceivable. Preferred examples of water-insoluble crosslinked polymers include polyvinylpolypyrrolidone, which is a crosslinked product of polyvinylpyrrolidone, crosslinked polysaccharides made water-insoluble by crosslinking water-soluble polysaccharides, such as crosslinked polysaccharides with epoxy, and esters. Examples include crosslinked ones and ether crosslinked ones.

Note that when ethanol and polyvinylpolypyrrolidone were used together with menthol, the effect of suppressing the dissipation of menthol was significantly obtained.

It is sufficient to add menthol in an amount that targets the desired flavor. One standard for preferable menthol flavoring is that the menthol content of the electronic cigarette filler obtained in step S103 is 0.1% by mass or more and 10% by mass or less. More preferably, it is 0.2% by mass or more and 5% by mass or less.

In forming the filler for electronic cigarettes, the amount of water-insoluble crosslinked polymer added is preferably 10 parts by mass or more and 2000 parts by mass or less, and 50 parts by mass or more and 600 parts by mass or less, based on 100 parts by mass of menthol. It is more preferable that there be. In other words, the content of the water-insoluble crosslinked polymer in the filling for electronic cigarettes is preferably 0.1 times or more and 20 times or less than the menthol content, and preferably 0.5 times or more and 6 times or less. is more preferable.

In order to achieve the effect of suppressing menthol dissipation, the water-insoluble crosslinked polymer is preferably present in an amount of 2% by mass or more, more preferably 4% by mass or more in the electronic cigarette filler. . By having such an amount present, long-term storage is possible while suppressing the dissipation of menthol, and even after long-term storage, the refreshing feeling of menthol can be enjoyed. Further, the content of the water-insoluble crosslinked polymer in the filler for electronic cigarettes is preferably 20% by mass or less, and more preferably does not exceed 10% by mass. When the content is within 10% by mass, it is possible to maintain the flavor derived from non-plant-derived polyphenols and the like.

The lower alcohol used is preferably 50 parts by mass or more based on 100 parts by mass of menthol. Further, when the amount is 100 parts by mass or more, the water-insoluble crosslinked polymer can be sufficiently mixed while dissolving menthol.When it is 2,000 parts by mass or less, the residue of lower alcohol can be reduced in the subsequent process. , it is possible to make the manufacturing process efficient.

In the example,
100 parts by mass of menthol,
200 parts by mass of ethyl alcohol,
200 parts by mass of polyvinylpolypyrrolidone,
was weighed, menthol was dissolved in ethyl alcohol to obtain a menthol ethyl alcohol solution, and then polyvinyl polypyrrolidone was added to the menthol ethyl alcohol solution and mixed with stirring to obtain a menthol/ethyl alcohol/polyvinyl polypyrrolidone mixture. .

The process of preparing materials such as an aerosol former in step S101c will be explained. In step S101c, an aerosol former, flavor additive, preservative, binder, thickener, etc. are prepared.

In addition, a food preservative can be added if necessary. As a preservative, for example, sorbic acid, potassium sorbate, benzoic acid, sodium benzoate, etc. can be used.

As binders or thickeners etc., gums such as guar gum, xanthan gum, gum arabic and locust bean gum, cellulose binders such as hydroxypropylcellulose, carboxymethylcellulose, hydroxyethylcellulose, methylcellulose and ethylcellulose, such as starch, alginic acid, etc. Polysaccharides such as organic acids, conjugate base salts of organic acids such as sodium alginate, sodium carboxymethylcellulose, caranagin, agar and pectin can be used. You may use these in combination.

In the example, glycerin, propylene glycol, sodium carboxymethylcellulose, and methylcellulose were prepared. Furthermore, an aqueous xylitol solution obtained by stirring and mixing 100 parts by mass of xylitol and 400 parts by mass of water and glucomannan were prepared.

Next, step S102 will be explained. In step S102, the materials prepared in step S101 are weighed and mixed to obtain, for example, a slurry of a non-tobacco plant composition.

In the mixing step of step S102, a normal mixer can be used. For example, a mixer that mixes the materials in a mixing tank using stirring blades while applying shearing force is preferably used.

A non-tobacco plant composition is obtained by mixing a pulverized dry product of a non-tobacco plant, a menthol solution, an aerosol former, a binder or a thickener, and if necessary, water.

In the example,
100 parts by mass of dried pulverized black tea leaves,
25 parts by mass of menthol/ethyl alcohol/polyvinylpolypyrrolidone mixture,
Glycerin 30 parts by mass,
30 parts by mass of propylene glycol,
4 parts by mass of sodium carboxymethylcellulose,
15 parts by mass of methylcellulose,
Xylitol aqueous solution 8 parts by mass,
Glucomannan 1 part by mass,
was placed in a blender and mixed for 15 minutes to form a non-tobacco plant composition.

Step S103 will be explained. In step S103, the non-tobacco plant composition formed in step S102 is processed to obtain a filler for electronic cigarettes.

In step S103, first, the non-tobacco plant composition obtained in step S102 is formed into a sheet shape. The planar shape of the sheet is arbitrary.

In the examples, a three-roll mill (described in Example 7) was used to form the non-tobacco plant composition into a sheet. When a three-roll mill is used, a sheet of desired thickness can be formed using a doctor blade while performing kneading, dispersion, etc. by compression by being pushed between narrow rolls and shearing by a difference in roll speed. In addition, in order to form the non-tobacco plant composition into a sheet, a press roller or a press can be suitably used in addition to a three-roll mill.

In the step of forming the non-tobacco plant composition into a sheet, non-tobacco plants, an aerosol former, flavor additives, preservatives, binders or thickeners, water, etc. may be added as necessary.

Note that the water used in the production of electronic cigarette fillers is preferably sterilized or free of microorganisms. It is also preferable to use pure water obtained by reverse osmosis membrane or ion exchange.

In the example, the process of putting three non-tobacco plant compositions into a roll mill, adding 20 parts by mass of pure water while checking the state of the sheet, and pressing a doctor blade against the rolls to collect a sheet-like material was carried out for 8 days. The process was repeated several times to obtain a final sheet-like non-tobacco plant composition.

In the step of forming the non-tobacco plant composition into a sheet, the thickness of the sheet obtained is preferably 0.1 mm or more and 1.0 mm or less, more preferably 0.1 mm or more and 0.5 mm or less. In the example, the non-tobacco plant composition was formed into a sheet with a thickness of about 0.3 mm.

An example of one method is a method of filling a packaging member (151) or the like as shown in FIGS. 3, 4, and 10 to 12. As another method, as shown in FIGS. 2 and 7, a sheet having predetermined notches is processed into a desired shape to form a sheet-like member having notches, and then a sheet made as a filler (111) is formed into a desired shape. An example of a method is to form a notch after processing the material into the shape of , form a sheet-like member having the notch, and then fill it into a packaging sheet (150) or the like as a filler (111). Further, as an example of a possible method, after processing the created sheet into a desired shape and shaping it into the shape for filling, incisions are formed, and a packaging sheet (150) is formed as a sheet-like filling material (111) having incisions. For example, the method of filling Further, as an example of a possible method, after processing the created sheet into a desired shape and filling it into a packaging sheet (150) etc. as a filler, a notch is formed, and a filler in the form of a sheet member having a notch is formed. One method is to do so. Further, although the sheets have notches, they are connected by a portion without a notch.

Subsequently, incisions are made in the non-tobacco plant composition formed into a sheet. The cut is formed in the thickness direction of the sheet to a depth that does not penetrate the sheet, for example, to a depth of about half the thickness of the sheet. The cut can be formed using a cutter, for example, a rotary cutter with a rotary blade type.

Note that the formation of the incisions may be performed simultaneously with the step of forming the non-tobacco plant composition into a sheet shape.

Also in the example shown in FIG. 6J, the length of the Y-axis direction component of each cut (F) is longer than the length of the X-axis direction component.

With reference to FIG. 7, the process of manufacturing an electronic cigarette cartridge in step S104 will be described. FIG. 7 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 sheet (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. It is also good to apply an adhesive to the sides of the aerosol forming substrate (110) and fix it to the packaging sheet (150).

When manufacturing an electronic cigarette cartridge, for example, a sheet of the non-tobacco plant composition is cut in the Y-axis direction along the dotted line in FIG. 6B, and one or more cut sheets are used as tobacco packaging members. For example, a roll having an outer diameter of about 6.9 mm and long in the Y-axis direction is produced by wrapping it with paper. This roll is then cut into a length of 12 mm using a cutter to obtain an aerosol forming base material (110). The scroll is cut along the dashed line in FIG. 6B.

The aerosol forming base material (110) is, for example, an electronic cigarette filler according to the embodiment shown in FIG. The sheet of non-tobacco plant composition formed in F) is placed inside a cylindrical packaging member. Inside the packaging member, the filler for electronic cigarettes shown, for example, in FIG. 6C is arranged from one longitudinal end to the other end of an aerosol forming base material (110) having a length of 12 mm. The extending direction of the rectangular short side of the electronic cigarette filler is, for example, approximately parallel to the longitudinal direction of the aerosol forming base material (110).

In addition, an aerosol can be formed by arranging a rectangular sheet of electronic cigarette filler whose short side is less than 12 mm adjacent to the aerosol forming substrate (110) in the longitudinal direction or partially overlapping the same. A substrate (110) may also be formed.

The mass of the aerosol-forming base material (110) is, for example, about 0.29 g, and the volume filling ratio of the electronic cigarette filler to the volume of the aerosol-forming base material (110) is about 0.60. The filling rate of the filler for electronic cigarettes can be determined by taking into account the strength of the aroma given to the user, the ease with which the user can inhale, and the like. The volume filling ratio of the electronic cigarette filler to the volume of the aerosol-forming substrate (110) is preferably 0.55 or more and 0.65 or less.

In addition to the aerosol-forming substrate (110), a support element (300), a transfer member (130), and a mouthpiece (140) are provided. Then, these four elements are arranged adjacently in this order along one direction and wrapped with a packaging sheet (150) such as tobacco paper to manufacture an electronic cigarette cartridge. At this time, the aerosol forming base material (110) is such that the long side on which the notch (F) of the electronic cigarette filler is formed is the end side of the electronic cigarette cartridge, that is, the side opposite to the support element (300). are arranged so that Also, some adhesive is placed on the sides of the support element (300).

When constructing an electronic cigarette cartridge (100) using a filler for electronic cigarettes, for example, the aerosol forming base material ( 110) and an electronic cigarette cartridge (100).

Also in the electronic cigarette cartridge (100) manufactured using the electronic cigarette filler according to the modified example, the heating element (211) is smoothly introduced into the engineered arosol-forming substrate (110).

In addition, in the electronic cigarette cartridge (100), the electronic cigarette filler is arranged such that the length of the longitudinal component of the notch (F) in the cartridge is longer than the length of the in-plane component perpendicular to the longitudinal direction. It is fine if it is done.

Although the present invention has been described above with reference to examples and the like, the present invention is not limited thereto.

For example, in the embodiments, the cut (F) is formed in a straight line, but it may be formed in a curve. As in the embodiments, the length of the Y-axis direction component of the cut (F) is made longer than the length of the X-axis direction component.

Furthermore, in the electronic cigarette cartridge (100) according to the embodiment, a lid may be disposed on the upstream side (10) of the aerosol-forming substrate (110). This can suppress the dissipation of the aroma of the electronic cigarette filler, and also prevent the electronic cigarette filler from falling off from the electronic cigarette cartridge (100), for example, when transporting the electronic cigarette cartridge (100). It is possible.

The lid can be made of a filter, paper, sponge, etc. Note that insertion of the heating element (211) can be facilitated by, for example, making one or more cuts in the lid. A guide hole, such as a circle or a polygon, may be provided where the heating element (211) is inserted.

Furthermore, in the electronic cigarette cartridge (100) according to the embodiment, a partition member may be provided between the aerosol-forming substrate (110) and the support element (300). The partition member can be made of, for example, a filter, paper, etc. with good air permeability. It is preferable that the heating element (211) be destroyed when inserted. By providing the partition member, it is possible to prevent the electronic cigarette filler from moving within the electronic cigarette cartridge (100) during transportation of the electronic cigarette cartridge (100).

Additionally, the electronic cigarette cartridge 100 according to the embodiment may be used by being attached to an electronic cigarette body that does not have a heating element.

Next, a usage example of the electronic cigarette cartridge of the present invention will be described in detail. As shown in FIG. 2, the electronic cigarette cartridge (100) has, for example, a rod-like or cylindrical appearance. Inside the electronic cigarette cartridge (100), an aerosol-forming substrate (110) is provided at one end, and a support element (300) and a transfer member (130) are arranged in this order toward the mouthpiece (140) at the other end. It is located in As shown in FIGS. 2 and 7, these are packaged with a packaging sheet (150).

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

The filler as the aerosol-forming substrate (110) is used in the form of a rolled or folded sheet. A state in which the sheets are rolled up, folded, compressed, or contracted when gathering the sheets is included in the form of rolling or folding. It is also preferable that the sheet is treated with wrinkles, pleats, etc.

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-forming substrate (110) can The aerosol can be directed towards the mouthpiece (140).

The mouthpiece (140) is positioned adjacent the transfer member (130) and downstream (20) 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 the function of cooling the generated aerosol. Instead of adding a transfer member (130), it is also preferred to extend the mouthpiece so that it adjoins or contacts 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 wrapped in a crimped polymer sheet in the longitudinal direction of the electronic cigarette cartridge can be used.

FIG. 8(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). .

The partition member (180) 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 moving within the electronic cigarette cartridge due to physical distribution during transportation or the like.

In FIG. 8(3), it is also preferable to cover the side of the aerosol forming substrate (110) into which the heating element (211) is inserted with a lid (170). 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 outward from 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 in the place where the heating element is inserted. It is a form.

The present invention will be explained in detail below. The electronic cigarette cartridge prepared in the following example was evaluated using an electronic cigarette main body as shown in FIG. An outline of the electronic cigarette body to be used will be explained.

The heating element (211) has a width of 4.5 mm, a length to the tip of 12 mm, and a thickness of 0.4 mm. The inner diameter of the insertion portion (210) is 7 mm, which is approximately equal to the outer diameter of the electronic cigarette cartridge. The heating element (211) generates heat at approximately 370° C. using electric power supplied from a battery (not shown) provided in the electronic cigarette body (200). And the built-in control system ends the consumption of one electronic cigarette cartridge after 14 puffs. Note that when the electronic cigarette cartridge of this embodiment is inserted, the portion of the electronic cigarette cartridge that appears outward from the downstream side of the electronic cigarette main body is approximately 20 mm.

(Example 1)
A slurry containing cellulose fibers, a binder, black tea, an aerosol former, and a flavor additive was cast onto a metal plate, and the cast slurry was dried to create a sheet. The thickness was set to 0.2 mm. The sheet obtained above was cut to a length of 12 mm and a width of 120 mm. The mass was 0.29g. As shown in Figure 9, from two-thirds of the length (A) in the vertical direction (Y direction), use a cutter to make cuts with a length of 8 mm in the vertical direction corresponding to two-thirds of the way (F) at intervals of 4 mm. I put it in. This was repeated to make cuts (F) in the lateral direction (X direction).

As an electronic cigarette cartridge, an aerosol forming base material (110) configured as shown in FIGS. 2 and 7 is made by filling a cylindrical packaging member (151) with a diameter of 7 mm and a height of 12 mm. It is formed. Moreover, a hollow tube having a through hole in its center is used as the support element (300). The diameter of the bottom of the tube is 7 mm, the diameter of the through hole forming the hollow portion is 3 mm, and the material is cellulose acetate. The support element (300) has the function of supporting the aerosol-forming substrate (110) against the insertion force when the heating element (211) is inserted, and also allows the generated aerosol to reach the user's mouth. It has a through hole to guide the aerosol from the upstream side (10) to the downstream side (20).

The transfer member (130) is a polymer sheet with gathers wrapped in paper so as to have a cylindrical shape with a bottom diameter of 7 mm and a height of 18 mm. The transfer member (130) has the function of guiding the generated aerosol from the upstream side (10) to the downstream side (20) so that it reaches the user's mouth, and also has the function of maintaining the temperature of the aerosol at an appropriate level.

The mouthpiece (140) used was a filter wrapped in paper so that it had a cylindrical shape with a bottom diameter of 7 mm and a height of 7 mm. The above is made into an electronic cigarette cartridge wrapped with a packaging sheet (150) as shown in FIGS. 2 and 7.

The filler (111) having the notches (F) as described above was wound to form a roll, and the packaging member (151) was filled with the filler to form an aerosol-forming base material (110). In the thus formed aerosol forming base material (110), the gaps between the sheets serve as air passages, and the air passages are formed in the longitudinal direction of the electronic cigarette cartridge. Note that when filling, since adhesive is applied to the side surface of the filling material, it is adhered to the packaging member (151). Note that the filling is done so that the side where the cut (F) is made is the upstream side (10). An electronic cigarette cartridge was obtained as described above.

In the case of this embodiment, the end shape of the sheet appearing at one end has a long side of 4 mm, and a substantially rectangular surface with a short side of 0.2 mm is deformed and is in a slightly curved state. However, as shown in FIG. 10, the areas of the edge shapes of the sheets observed from the center (B) to the peripheral area (C) of the aerosol forming substrate viewed from one end of each are approximately equal. It has the characteristic of being

With such a feature, when the heating element (211) is inserted, it can be mounted with a constant resistance regardless of the direction of insertion. Furthermore, since the air passage formed by the aerosol generated by heating is uniform, the feeling of inhalation is stable. Further, after use, there was no part of the filling material falling off, and there was no falling off of the filling material.

(Example 2)
A filling (111) with cuts similar to those in Example 1 was prepared. The sheet with the cuts (F) was folded and filled into the packaging member (151) to obtain a filling. The filler formed in this way has air passages between the sheets, and the air passages are formed in the longitudinal direction of the electronic cigarette cartridge. In addition, since adhesive is applied to the side surface of the filling material during filling, it is adhered to the packaging member (151). Note that the filling is done so that the side where the incision was made is the upstream side. As described above, an electronic cigarette cartridge was obtained in the same manner as in Example 1.

In the case of this embodiment, the end shape of the sheet appearing at one end has a long side of 4 mm, and a substantially rectangular surface with a short side of 0.2 mm, which is in a deformed state. However, as shown in Figure 10, the areas of the edge shapes of the sheet observed from the center (B) to the periphery (C) of the aerosol forming substrate viewed from each end are approximately equal. It has the characteristic of being

With such a feature, when the heating element (211) is inserted, it can be mounted with a constant resistance regardless of the direction of insertion. Furthermore, since the air passage formed by the aerosol generated by heating is uniform, the feeling of inhalation is stable. Further, after use, there was no part of the filling material falling off, and there was no falling off of the filling material.

(Example 3)
A slurry containing cellulose fibers, a binder, black tea, an aerosol former, and a flavor additive was cast onto a metal plate, and the cast slurry was dried to create a sheet. The thickness was set to 0.2 mm. The cut sheet was rolled to form a roll, and the packaging member (151) was filled with it to form a filling. The filler formed in this way has air passages between the sheets, and the air passages are formed in the longitudinal direction of the electronic cigarette cartridge. In addition, since adhesive is applied to the side surface of the filling material during filling, it is adhered to the packaging member (151).

Thereafter, cuts (D1, D2, D3) were made in the diametrical direction from one end using a cutter. As shown in FIG. 11, the cuts (D1, D2, D3) were made at three equal intervals in the diametrical direction. The cutting depth is approximately 8 mm. As described above, an electronic cigarette cartridge was obtained in the same manner as in Example 1.

In the case of this example, the area of the edge shape of the sheet observed from the center (B) to the peripheral area (C) of the aerosol forming substrate as viewed from each end increases from small to large. It has the characteristic of being In such a structure, when inserting the heating element (211), the present structure has an advantage in that the resistance at the center is small. Further, after use, there was no part of the filling material falling off, and there was no falling off of the filling material.

(Example 4)
A slurry containing cellulose fibers, a binder, black tea, an aerosol former, and a flavor additive was cast onto a metal plate, and the cast slurry was dried to create a sheet. The thickness was set to 0.2 mm. The sheet obtained above was cut to a length of 12 mm and a width of 120 mm. The cut sheet was folded and filled into the packaging member (151) to obtain a filling material. The filler formed in this way has air passages between the sheets, and the air passages are formed in the longitudinal direction of the electronic cigarette cartridge. In addition, since adhesive is applied to the side surface of the filling material during filling, it is adhered to the packaging member (151).

After that, a cut was made from one end using a cutter. As shown in FIG. 12, three cuts (G1, G2, G3) were made so that the cuts were approximately perpendicular to the ridgeline of the folded filling material (111). The cutting depth is approximately 8 mm. As described above, an electronic cigarette cartridge was obtained in the same manner as in Example 1. Further, after use, there was no part of the filling material falling off, and there was no falling off of the filling material.

(Example 5)
A slurry containing cellulose fibers, a binder, black tea, an aerosol former, and a flavor additive was cast onto a metal plate, and the cast slurry was dried to create a sheet. The thickness was set to 0.2 mm. The sheet obtained above was cut to a length of 12 mm and a width of 120 mm, and crimped so as to have a waveform substantially parallel to the transverse direction (Y direction). One period of the waveform is 4 mm. The crimped sheet as described above was rolled to form a roll, and the packaging member (151) was filled with it to form a filling. The filler formed in this way has air passages between the sheets, and the air passages are formed in the longitudinal direction of the electronic cigarette cartridge. In addition, since adhesive is applied to the side surface of the filling material during filling, it is adhered to the packaging member (151).

Cuts (D1, D2, D3) were made in the diametrical direction from one end using a cutter. The cuts (D1, D2, D3) were made so that they were equally spaced in the diametrical direction, as shown in Figure 11. The cutting depth is approximately 8 mm. The cutting depth is approximately 8 mm. As described above, an electronic cigarette cartridge was obtained in the same manner as in Example 1.

In the case of this example, the area of the edge shape of the sheet observed from the center (B) to the peripheral area (C) of the aerosol forming substrate as viewed from each end increases from small to large. It has the characteristic of being In such a structure, when inserting the heating element (211), the present structure has an advantage in that the resistance at the center is small.

Further, after use, there was no part of the filling material falling off, and there was no falling off of the filling material. This is thought to be due to the crimping, but when the heating element (211) is inserted, it can be worn with a certain amount of resistance regardless of the direction of insertion, resulting in a stable suction comfort.

(Example 6)
A slurry containing cellulose fibers, a binder, black tea, an aerosol former, and a flavor additive was cast onto a metal plate, and the cast slurry was dried to create a sheet. The thickness was set to 0.2 mm. The sheet obtained above was cut to a length of 12 mm and a width of 120 mm, and crimped so as to have a waveform substantially parallel to the transverse direction (Y direction). One period of the waveform is 4 mm. The sheet crimped as described above was folded and filled into the packaging member (151) to form a filling. The filler formed in this way has air passages between the sheets, and the air passages are formed in the longitudinal direction of the electronic cigarette cartridge. In addition, since adhesive is applied to the side surface of the filling material during filling, it is adhered to the packaging member (151).

After that, a cut was made from one end using a cutter. As shown in FIG. 12, three cuts (G1, G2, G3) were made so as to be approximately perpendicular to the folded filling material (111). The cutting depth is approximately 8 mm. As described above, an electronic cigarette cartridge was obtained in the same manner as in Example 1. Further, after use, there was no part of the filling material falling off, and there was no falling off of the filling material. This is thought to be due to the crimping, but when the heating element (211) is inserted, it can be worn with a certain amount of resistance regardless of the direction of insertion, resulting in a stable suction comfort.

(Example 7)
In this embodiment, a configuration particularly suitable for continuously producing a sheet having a notch at one end will be described. A slurry containing cellulose fibers, a binder, black tea, an aerosol former, and a flavor additive was cast onto a metal plate, and the cast slurry was dried to create a sheet. The sheet obtained above was made into a continuous sheet having a width of 120 mm and wound into a roll. From the roll, a continuous sheet was fed to a roll rotary cutter to make partial cuts.

FIG. 13 shows how to make the cuts in this embodiment. Cuts are made at intervals W in the X direction on a sheet measuring 120 mm in the X direction. Non-cut portions H1 and cut portions H2 are periodically formed at intervals of length H in the Y direction. Further, adjacent cuts are formed with a difference of H3. FIG. 14 shows an example in which the sheet formed as described above is cut into lengths H at intervals.

In FIG. 14, in the X direction, there are cut portions and non-cut portions at intervals of width W, and the entire formed sheet is connected by the non-cut portions. Furthermore, in the Y direction, there are two sides in the X direction, and cuts are present on the two sides. That is, when a packaging member (151) is filled with the sheet having the notches of this example to form an aerosol forming base material, both the upper surface and the lower surface are filled with a filler having the notches. This method of forming an aerosol-forming substrate is suitable for continuous production. This is because either orientation of the aerosol-forming substrate can be used, making it suitable for automated assembly of electronic cigarette cartridges.

Although the present embodiment has been described using the above-mentioned specific example, the present invention is not limited to this method. In continuous production, the length H2 of the cut must be smaller than the width of the sheet in the Y direction in order to make the entire formed sheet continuous with no cuts. This can be achieved by arranging the cuts so as to create cuts on both one end and the other end. That is, it is a sheet-like member in which cut portions are present at predetermined intervals in a direction transverse to the longitudinal axis of the electronic cigarette cartridge, and the entire sheet-like member is connected by a non-cut portion; When a sheet-like member is used as an aerosol-forming base material, it is possible to create an aerosol-forming base material in which cuts are present on one end side and the other end side.

Here, the interval W is 4 mm, the length H is 12 mm, H1 is 4 mm, H2 is 8 mm, and H3 is 2 mm. In this example, the length H is set to 12 mm in order to align the length of the aerosol forming base material in the longitudinal direction of the electronic cigarette cartridge with the length of the filler in the longitudinal direction. As described above, an electronic cigarette cartridge was obtained in the same manner as in Example 1. Further, after use, there was no part of the filling material falling off, and there was no falling off of the filling material. This is thought to be due to the crimping, but when the heating element (211) is inserted, it can be worn with a certain amount of resistance regardless of the direction of insertion, resulting in a stable suction comfort.

A preferred manufacturing method for the embodiment 7 will be explained. As an example, FIG. 15 shows an outline of an aerosol-forming base material manufacturing apparatus (600). A sheet is supplied from a sheet supply device (610) including a rotatable bobbin, and a predetermined incision is made in the supplied sheet. A predetermined notch is created using a notch forming device (620) such as a rotary cutter. Subsequently, the sheets with the desired incisions are guided to a gathering device (630) such as a funnel, where they are rolled up, folded, compressed, or contracted to gather the sheets. It is preferable that a collection of sheets created in this manner has an air passage between the sheets, and the air passage is formed along the longitudinal direction of the electronic cigarette cartridge. . On the other hand, in order to fill the packaging member (151) with the sheets, packaging paper is supplied from a packaging member supplying device (670) equipped with a roll of packaging paper that will become a packaging member, and the assembled sheets are collected in a collection device (630). Pack it. This packaging process is performed by a packaging device (640). In the packaging device (640), the assembled sheets are wrapped with the packaging sheet, and an adhesive is applied to the overlapped ends of the wrapping paper for thermal welding, bonding is performed by heating, cooling is performed, and the sheets are continuously wrapped. Generally, the assembled sheets wrapped by the wrapping paper are continuously formed into individual aerosol-forming substrates (110) by a cutting device (650). Although not shown, a three-roll mill is used upstream of the sheet supply device (610) to form the non-tobacco plant composition into a sheet.

In addition, the assembled sheets produced by the collecting device (630) or the wrapping device (640) and wrapped with packaging members are guided from the collecting device (630) to the cutting device (650) by a belt drive device (660). It will be destroyed. The belt used in the belt drive device (660) is preferably a garniture belt. Incisions are formed at one end and the other end of the aerosol forming base material (110) formed in this way, and the entire formed sheet is connected by a portion without incisions.

As explained above, the present invention provides the following effects.
The heating element (211) can be stably inserted into the electronic cigarette cartridge. Accordingly, the feeling of smoking becomes stable, and it is possible to prevent damage to the electronic cigarette cartridge and further damage to the heating element (211).

Further, after the electronic cigarette cartridge is used, it is also possible to prevent the filler of the aerosol-forming base material from falling off.

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. It will be obvious to those skilled in the art that various other changes, improvements, combinations, etc. are possible.
