Description

TECHNICAL FIELD The present invention relates to a cartridge for a smoking device that is used by being attached to an induction heating type smoking device.

In recent years, tobacco products have become widely known that heat a cigarette cartridge containing tobacco components without using a flame and inhale the vaporized tobacco components. Furthermore, due to the diversification of tastes, smoking devices using cartridge products are becoming popular, which allow people to enjoy the aroma and taste of plants that do not contain tobacco components, without using a flame, just like with cigarettes.

In such a smoking device, an aerosol is generated by heating a filler aggregate in which fillers are accumulated. As a method for heating a filling assembly, it is known to heat the filling by providing a susceptor member made of a magnetic material inside the filling assembly and heating the susceptor member by induction from a smoking tool. For example, there is a cartridge for a smoking device in which a susceptor member is provided in the filler assembly as described in Patent Document 1.

Special Publication No. 2017-519493

However, since the susceptor member described in Patent Document 1 is formed by forming multiple layers of multiple types of metals, it is difficult to manufacture the susceptor member. Therefore, providing such a susceptor material in a smoking article cartridge increases the manufacturing cost of the smoking article cartridge, which is not preferable. In addition, since it was exclusively in a flat plate shape, the filling material could only be heated locally, resulting in poor efficiency.

The present invention has been made in view of the above problems, and it is an object of the present invention to provide a cartridge for a smoking device that has a simple structure and is provided with a susceptor member. Another object of the present invention is to provide a cartridge for a smoking device that is provided with a susceptor member that can heat the filling over a wide range.

(Overall configuration of cartridge for smoking implements)
Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a cross-sectional view of a smoking article cartridge 1 having a filler assembly 10 according to the present embodiment. As shown in this figure, the smoking article cartridge 1 includes a substantially cylindrical filling assembly 10 filled with a large number of filling materials 20, and a support member 12 through which airflow from the filling material assembly 10 can pass. , a mouthpiece 14 having a mouthpiece 14a at one end and a sealing member 18 having an inlet 18a at the other end are arranged along the longitudinal direction and are integrated by being wrapped with a sheet-like packaging member 16. has been done. The packaging member 16 can be made of paper or the like.

In this embodiment, the smoking article cartridge 1 is formed to have a diameter of 4.0 mm to 7.5 mm, more preferably 5.0 mm to 7.0 mm, and a length of 40 mm to 80 mm. If the outer diameter of the smoking article cartridge 1 is set in the range of 6.5 to 7.5 mm, the diameter will be smaller than the insertion part 51 provided in the smoking article 2 into which the smoking article cartridge 1 is inserted, and the smoking article cartridge 1 into the smoking implement 2 becomes easy. If the length of the smoking article cartridge 1 is set in the range of 40 to 80 mm, it will be longer than the length of the insertion part 51 provided in the smoking article 2 that receives the smoking article cartridge 1. Even when inserted into the smoking tool 2, the mouthpiece 14a can be exposed from the smoking tool 2, and the length necessary for the smoker to smoke can be ensured.

(Structure of support member)
The support member 12 suppresses the movement of the filling material assembly 10 toward the support member 12 side, and allows the airflow containing the aerosol generated in the filling material assembly 10 to flow toward the mouthpiece 14 side. The support member 12 is provided, for example, in a cylindrical and solid shape, and is disposed between the filling material assembly 10 and the mouthpiece 14 so that its axial direction is along the central axis. The support member 12 is formed, for example, to have an outer diameter of 4.0 mm to 7.5 mm and a length along the central axis of 50 mm or less. Note that the support member 12 may have dimensions different from those described above depending on the function and configuration as appropriate.

The support member 12 is made of resin material. Examples of the resin material forming the support member 12 include polypropylene, polylactic acid, and silicone. However, the support member 12 may be formed of a resin material other than this, or a material other than the resin material, such as wood or metal (aluminum, etc.) that increases the cooling effect. Note that the support member 12 is not necessarily necessary, and as long as the filling material assembly 10 does not easily move toward the mouthpiece 14 (for example, the filling material collection 10 is fixed to the packaging member 16), The support member 12 may not be provided.

(Mouthpiece configuration)
The mouthpiece 14 is formed into a cylindrical shape, and has a diameter of, for example, 4.0 mm to 7.5 mm, and a length along the central axis of 50 mm or more. The mouthpiece 14 is formed using paper or the like, for example. Further, the mouthpiece 14 may be provided in a cylindrical shape by winding a sheet-like member made of paper, for example, or may include a cellulose acetate filter for removing fine particles. The mouthpiece 14 is a white filter that has the function of filtering part of the particulates in the water vapor and aerosol generated in the filling assembly 10. Note that the mouthpiece 14 is not necessarily necessary because the filler 20 is made from a non-tobacco plant as described below.

(Configuration of filling aggregate)
The filling material assembly 10 is formed by forming a bundle of elongated filling material 20 along the length direction and wrapping it around a sheet-like packaging member 25 to form a substantially cylindrical shape. Filling 20 is formed from tobacco or non-tobacco plants. The filler 20 is not limited to a long shape, and may have other shapes such as granules, dust, paste, and porous shapes. The filling mass 10 has a length of 10 to 25 mm. Incidentally, the smoking implement cartridge 1 may have dimensions different from those described above in accordance with the shape of the smoking implement 2.

The outer diameter of the filling assembly 10 is equal to the outer diameter of the support member 12 and the mouthpiece 14, and is approximately constant along the central axis. The size of this outer diameter is preferably in the range of 4.0 mm to 7.5 mm, and more preferably in the range of 5.0 mm to 7.0 mm.

A susceptor member 30 is provided inside the filling assembly 10 . The susceptor member 30 can be inductively heated by an external magnetic field. Therefore, the susceptor member 30 is formed of a metal material containing a magnetic material. Magnetic materials are broadly classified into ferromagnetic materials, paramagnetic materials, and diamagnetic materials. Among magnetic materials, ferromagnetic materials are materials that become strongly magnetic in the same direction as the external magnetic field when an external magnetic field is applied, and strong magnetism remains even when the external magnetic field is reduced to zero.For example, iron, which is a ferromagnetic material, Examples include ferrite iron, ferrite powder, ferrite particles, ferritic stainless steel, ferromagnetic steel, stainless steel, nickel, and cobalt. The relative magnetic permeability of ferromagnetic materials is extremely larger than 1, for example, iron is about 5000, nickel is about 600, cobalt is about 250, and ferritic stainless steel is about 250. It is about 1000 to 1800.

Among magnetic materials, paramagnetic materials are materials that are weakly magnetized in the same direction as the external magnetic field when an external magnetic field is applied, and cease to be magnetic when the external magnetic field is reduced to zero, such as aluminum, platinum, and manganese. . The relative magnetic permeability of paramagnetic materials is slightly larger than 1, for example, aluminum is about 1.000021, platinum is about 1.000265, and manganese is about 1.000830.

Among magnetic materials, diamagnetic materials are materials that become magnetic in the opposite direction to the external magnetic field when an external magnetic field is applied, and cease to be magnetic when the external magnetic field is reduced to zero, such as copper, graphite, bismuth, and chromium. Can be mentioned. The relative magnetic permeability of diamagnetic materials is slightly smaller than 1, for example, copper is about 0.999990, graphite is about 0.99980, and bismuth is about 0.999834. .

In ferromagnetic materials, when an alternating magnetic field is generated, not only does an induced current flow and Joule heat is generated, but also heat (hysteresis loss) is generated due to friction and vibration between molecules, so it is different from paramagnetic and diamagnetic materials. In comparison, induction heating is easier, and the packing assembly 10 can be sufficiently heated.

Further, ferromagnetic materials have a high Curie temperature, for example, nickel has a high Curie temperature of about 358°C. Therefore, even when the smoking article cartridge 1 is heated to a high temperature of, for example, 200° C., the heating temperature does not reach the Curie temperature, and the properties as a ferromagnetic material can be maintained, and the filling assembly 10 can be heated stably. can.

The susceptor member 30 is made of ferromagnetic materials such as iron, ferrite iron, ferrite powder, ferrite particles, ferritic stainless steel, ferromagnetic steel, stainless steel, nickel, cobalt, or a combination of these. May be adopted. For example, it may be a combination of ferritic stainless steel and nickel, and more preferably an alloy that is a combination of iron, chromium, and aluminum (iron-chromium aluminum alloy).

Here, to explain the relationship between temperature and magnetism of iron and chromium, the Curie temperature of iron, which is the temperature at which it changes from ferromagnetic to paramagnetic, is approximately 770°C, and that of chromium, which changes from antiferromagnetic to paramagnetic. The Neel temperature, which is the temperature at which the temperature changes, is about 35°C.

Further, the susceptor member 30 may be made of a metal material containing a ferromagnetic material as a main component, for example, a ferromagnetic alloy containing 60% or more, preferably 80% or more of a magnetic material may be used. good. For example, a nickel alloy or a nickel-iron alloy may be used. Even in this case, the filling assembly 10 can be sufficiently heated by induction heating the ferromagnetic material. Note that a metal material containing a paramagnetic material and a diamagnetic material may be used instead of a ferromagnetic material. Even in this case, induction heating itself is possible. However, from the viewpoint of shortening heating time and reducing power consumption, it is preferable to use a metal material containing a ferromagnetic material.

The susceptor member 30 may be made of a combination of ferromagnetic, paramagnetic, or diamagnetic materials. For example, a first susceptor member made of nickel, which is a ferromagnetic material, and a second susceptor member made of iron, which is a ferromagnetic material, are physically brought into close contact, or Examples include a method in which a susceptor member and a third susceptor member made of aluminum, which is a paramagnetic material, are physically brought into close contact, and an outer surface of the first susceptor member is covered with a third susceptor member. . The arrangement of the susceptor member 30 will be described later.

The susceptor member 30 accounts for 100% of the total length of the filling material assembly 10. That is, the susceptor member 30 has a length that spans the entire length of the filler assembly 10. The susceptor member 30 does not need to span the entire length of the filler assembly 10, and may have a length that accounts for 25% or more and 100% or less of the total length of the filler assembly 10. Thereby, the temperature of the filling material 20 can be reliably raised by the susceptor member 30.

(Structure of seal member)
The seal member 18 is formed into a cylindrical shape, and has a diameter of, for example, 4.0 mm to 7.5 mm, and a length along the central axis of 50 mm or less. Like the mouthpiece 14, the sealing member 18 may be provided in a cylindrical shape by winding a sheet-like member made of paper, for example. The sealing member 18 has a function of allowing air to pass from the introduction portion 18a, that is, the upstream side, toward the filling material assembly 10. Further, the sealing member 18 can absorb residual liquid that remains in the filling assembly 10 and liquefies among the water vapor and aerosol generated in the filling assembly 10. By making the sealing member 18 a different color from the mouthpiece 14 (for example, black), it is possible to easily determine the upstream side and the downstream side of the smoking article cartridge 1.

(How to use the cartridge for smoking implements)
FIG. 2 shows a cross-sectional view showing how the smoking article cartridge 1 is used. The smoking implement cartridge 1 is used with the sealing member 18 side attached to the smoking implement 2. The smoking implement 2 has an insertion portion 51 into which the smoking implement cartridge 1 is inserted. The smoking tool 2 is provided with an induction heating section 52 along the insertion section 51. The induction heating section 52 includes an induction coil, and can heat the susceptor member 30 by being inductively coupled to the susceptor member 30 included in the filling material assembly 10 inserted into the insertion section 51 . By heating the susceptor member 30, the surrounding filling material 20 is heated, and an aerosol can be generated. In this state, by inhaling through the mouthpiece 14, the smoker can inhale the airflow containing the aerosol.

Furthermore, the smoking implement 2 can detect the temperature of the susceptor member 30. As a specific example, the induction heating section 52 heats the susceptor member 30 by the magnetic force supplied to the susceptor member 30, and periodically (for example, once every 1 ms), the induction heating section 52 heats the susceptor member 30 using the magnetic force supplied to the induction heating section 52. By detecting the apparent ohmic resistance of the susceptor member 30 determined from the power supply voltage and the DC current drawn from the DC power supply, the resistance value of the susceptor member 30 at the time of the detection can be detected. In other words, when the susceptor member 30 is made of an iron-chromium aluminum alloy, the magnetism of chromium changes from antiferromagnetic to paramagnetic at 35°C, and the magnetism of iron changes from ferromagnetic to paramagnetic at 770°C. 2 can detect whether the temperature of the susceptor member 30 is less than 35°C, 35°C or more and less than 770°C, or 770°C or more, based on the apparent ohmic resistance of the susceptor member 30.

(Composition of filling)
The filling 20 is made by mixing dried and crushed non-tobacco plants with an aerosol former that generates an aerosol, microcrystalline cellulose, flavor additives, preservatives, adhesives, thickeners, etc., and then forming the mixture into a sheet. It is formed by molding it into a shape and then cutting it to have a predetermined width and length. Note that the filler 20 is not limited to a long shape, and may have various shapes. For example, it may be formed into a paste form or a granule form.

When the filling 20 is configured in a long shape, the cross section perpendicular to the central axis is approximately rectangular, and the ratio of the long side to the short side of the cross section is, for example, in the range of 1:1 to 30:1. It is preferable. The length of the long side is preferably in the range of 0.1 mm to 7.5 mm, more preferably in the range of 0.1 mm to 3.0 mm. The length of the short side is preferably in the range of 0.1 mm to 1.0 mm, more preferably in the range of 0.1 mm to 0.5 mm. Further, it is preferable that the length of the filler 20 is approximately the same as the length of the filler aggregate 10. The length of the filler 20 is preferably in the range of 10 mm to 25 mm, more preferably in the range of 10 mm to 20 mm. An example of the dimensions of such a filling 20 is that the long side is 1.5 mm, the short side is 0.3 mm, and the length is 12 mm.

Next, specific examples of raw materials used as the filler 20 will be described. The filling 20 is composed of any one or a combination of the following raw materials.

The filling 20 is made from tobacco plants or non-tobacco plants. Examples of tobacco plants include tobacco leaves, tobacco stems, expanded tobacco, homogenized tobacco, and the like. Non-tobacco plants include plants other than tobacco plants. Preferred parts of non-tobacco plants include leaves, pulp, seeds, roots (scaly roots, tuberous roots, etc.), stems, tubers, skin (stem bark, bark, etc.), flowers (petals, stamens, pistils, etc.), trunks, and branches. etc.

In addition, "plant" as used herein refers to a group of animals, and includes not only living organisms that have roots and live in a fixed location, such as grass and trees, but also microalgae, seaweed, etc. It also includes algae such as , fungi such as mushrooms, etc.

The filling 20 is, for example, made by appropriately mixing dried and crushed non-tobacco plants with an aerosol former that generates an aerosol, microcrystalline cellulose, additives that add flavor, preservatives, binders, thickeners, etc. It is crushed or classified into powder or granules, or formed into a paste. Further, the aerosol forming base material 23 is formed into a sheet shape and then cut into a strip or rod shape having a predetermined width and length.

For example, when the part of a non-tobacco plant is a leaf, tea can preferably be used. Not only do teas come from different plants, but even the same plant can be made into different teas depending on the processing method. Specifically, for example, Japanese tea, black tea, tomorrow leaf tea, sweet tea, Jiaogulan tea, aloe tea, ginkgo biloba tea, oolong tea, turmeric tea, eulogna tea, eleuthero tea, plantain tea, persimmon leaf tea, persimmon leaf tea, Chamomile tea, chamomile tea, Kawahara Keimei tea, quince tea, chrysanthemum tea, gymnema tea, guava tea, goji tea, soft leaf tea, black soybean tea, gennoshoko tea, genmaicha, burdock tea, comfrey tea, bifu tea , cherry blossom tea, saffron tea, shiitake tea, perilla tea, jasmine tea, ginger tea, horsetail tea, red scallion tea, Japanese japonica tea, buckwheat tea, ataranoki tea, dandelion tea, sweet tea, dokudami tea, duchu tea, nut bean tea, elderberry tea , rat glutinous tea, pearl barley tea, habu tea, loquat leaf tea, puerh tea, safflower tea, pine needle tea, yerba mate tea, barley tea, meguslin tea, mugwort tea, eucalyptus tea, luohanguo tea, rooibos tea, and bitter melon tea. For these teas, used tea leaves may be used. By using used tea leaves, you can reuse expensive tea and other items effectively.

Furthermore, extracts of non-tobacco plants such as those exemplified above, so-called extracts and processed products can also be used. Examples of the form of the extract include liquid, syrup, powder, granules, and solution.

The aerosol former as a raw material for the filler 20 includes glycerin, propylene glycol, sorbitol, triethylene glycol, lactic acid, diacetin (glycerin diacetate), triacetin (glycerin triacetate), triethylene glycol diacetate, and triethyl citrate. , isopropyl myristate, methyl stearate, dimethyl dodecanedioate, dimethyl tetradecanesanedionate, and the like. Among them, glycerin and propylene glycol are preferred.

Microcrystalline cellulose as a raw material for the filler 20 is obtained by partially depolymerizing α-cellulose obtained from the pulp of a fibrous plant with an acid, and is obtained by removing the soluble portion from the cellulose. , where appropriate, the insoluble portion is crystallized.

Microcrystalline cellulose may be used as a powder, or may be dispersed in a solvent such as water to form a suspension liquid. In this case, a high-speed stirrer, a high-pressure homogenizer, or the like can be used for dispersion in a solvent.

Furthermore, flavor additives that add flavor may also be preferably used as raw materials for the filling 20 if necessary. Flavor additives include mint, cocoa, coffee, black tea extracts, catechin powder from tea extracts, and the like. Preferably, the preservatives are those used in foods, such as sorbic acid, potassium sorbate, benzoic acid, and sodium benzoate.

The filler 20 may also contain menthol and a water-insoluble crosslinked polymer (preferably polyvinylpolypyrrolidone). By combining menthol with a water-insoluble crosslinked polymer, sublimation of menthol can be effectively suppressed and the flavor of menthol can be maintained for a long period of time. Here, menthol is not limited to those obtained from natural products, and may be synthetic products. Additionally, peppermint, mint, peppermint oil, and other substances containing menthol may be used.

The flavor additive is provided in the mouthpiece 14, for example, by impregnating the wall of the mouthpiece 14. The mode in which the flavor additive is provided in the mouthpiece 14 is not limited to this mode. For example, by embedding a capsule containing the flavor additive in the wall of the mouthpiece 14, the flavor additive can be provided in the mouthpiece 14. 14 may be provided with a flavor additive. Alternatively, a capsule containing a flavor additive may be placed between the mouthpiece 14 and the filling assembly 20. When the flavor additive is encapsulated in a capsule, the smoker can destroy the capsule by pressing the capsule with his or her fingers, allowing the aromatic components of the flavor additive to volatilize at the desired timing. Become.

Furthermore, if the flavor additive is encapsulated in microcapsules, for example, the encapsulated microcapsules may be provided in the filler assembly 10. Of course, the microcapsules may be provided on the support member 12.

Binders or thickeners as raw materials for the filling 20 include gums such as guar gum, xanthan gum, gum arabic and locust bean gum, cellulose binders such as hydroxypropylcellulose, carboxymethylcellulose, hydroxyethylcellulose, methylcellulose and ethylcellulose. Agents include starch, organic acids such as alginic acid, polysaccharides such as conjugated base salts of organic acids such as sodium alginate, sodium carboxymethylcellulose, caranagin, agar and pectin, and combinations thereof.

(Filling manufacturing process)
The manufacturing process of the filler 20 includes a drying/pulverizing process in which tobacco plants or non-tobacco plants, which are the main raw materials, are dried and crushed and weighed, a preparation process in which other raw materials are pretreated, weighed, etc. The method includes a mixing step of mixing to form a composition, and a filling molding step of molding the composition.

In the drying and pulverizing process, the parts of tobacco plants or non-tobacco plants that serve as the main raw materials (for example, leaves, seeds, dried fruits, stems, bark, roots, etc.) are processed into a specified pulverized product in order to create a composition. . At that time, it is preferable to adjust the amount of water to a level convenient for absorbing or supporting the aerosol former, water, and other components added later. In drying, the temperature is preferably 60°C or higher and 80°C or lower. By setting it within this range, it is easy to reach the desired moisture content while avoiding the dissipation of the necessary flavor components. Furthermore, the drying/pulverizing step may include a sieving step for sieving the pulverized material, so that the particle size can be adjusted to a desired size and then fed into the mixing step.

In the preparation process, raw materials necessary for producing the filling 20 can be prepared. The aforementioned microcrystalline cellulose is weighed in the preparation step and introduced into the mixing step.

In the mixing step, a conventional mixer can be used. For example, a configuration is preferably used in which the raw materials in the mixing tank are mixed using a stirring blade while applying shearing force.

In the filler forming step, a composition in which various raw materials are mixed is formed into a thin sheet shape and then cut to form a strip-shaped or rod-shaped filler 20. In this embodiment, a plurality of roll mills are prepared to make a thin sheet. When using a multi-roll mill, it is possible to form a sheet of the desired thickness using a doctor blade while performing kneading and dispersion through compression by being pushed between narrow rolls and shearing due to the difference in roll speed. ,preferable. Moreover, it can also be produced using a press roller or a press machine.

Further, in order to form the powdery or granular filler 20, it is preferable that the above-mentioned composition is appropriately pulverized or classified. The average particle diameter of the powdery or granular filler 20 is preferably, for example, 0.1 to 3.0 mm, and more preferably 0.5 mm or less. The average particle diameter is determined, for example, by the sieving method described in JIS K 0069:1992. In other words, this average particle diameter is the diameter corresponding to 50% of the mass obtained by integrating the mass of the test results using a plurality of sieves starting from the one with the largest opening. Alternatively, the particle size at an integrated value of 50% in the particle size distribution determined by a laser diffraction/scattering method may be taken as the average particle size.

In the filling molding step, other means may be used, such as molding the composition by passing it through an orifice under pressure. In addition, in the filling forming process, non-tobacco plants, aerosol formers, binders or thickeners, flavor additives, preservatives, etc. may be further added, or water may be added. Also good.

The thickness of the sheet obtained in the filling molding step is preferably in the range of 0.1 mm to 1.0 mm, more preferably in the range of 0.1 mm to 0.5 mm. The obtained sheet is cut into a predetermined width using a cutter, a rotary cutter with a rotating blade, or the like.

Here, when imparting tackiness to the surface of the filler 20, there is no particular limitation as long as it is a means capable of imparting tackiness, but the above-mentioned binder may be attached to at least a portion thereof. By imparting tackiness, when the strip-shaped or rod-shaped filler 20 is combined with the powder, granular, or paste-like filler 20, the surface of the strip-shaped or rod-shaped filler 20 is coated with powder, granules, or paste. The shaped filling 20 can be stably held.

(Shape and arrangement of susceptor member)
FIG. 3 shows a perspective view of the susceptor member 30, and FIG. 4 shows a sectional view taken along the II section in FIG. 1, respectively. As shown in FIG. 3, the susceptor member 30 is formed into an elongated rod shape as a whole. Specifically, the susceptor member 30 is formed into one rod shape by spirally bundling a plurality of metal wires 31 made of iron chromium aluminum alloy. Preferably, the susceptor member 30 is formed by bundling three metal wires 31 each having a diameter of 0.5 mm.

The susceptor member 30 can have a length that accounts for 25% or more and 100% or less of the total length of the filler assembly 10. In the present embodiment, all of the metal wires 31 are made of iron-chromium aluminum alloy, but in the susceptor member, some of the metal wires are made of ferromagnetic material, some of them are made of paramagnetic material, and the rest are made of antimagnetic material. A plurality of types of magnetic materials, such as a magnetic material, may be combined, and the number of metal wires 31 may be two or three or more. Further, the plurality of metal wires 31 may be welded using an adhesive or a welding material, and it is only necessary that the plurality of metal wires 31 can be thermally or electrically connected to each other.

As shown in FIG. 4, one susceptor member 30 is provided inside the filling assembly 10. The susceptor member 30 is arranged at the center of the filling assembly 10 when viewed in the radial direction. Thereby, the entire packing 20 of the packing material assembly 10 can be heated evenly and uniformly from the radial center of the packing material assembly 10, thereby efficiently generating aerosol.

Those skilled in the art will be able to come up with various changes and modifications within the scope of the present invention, and it is understood that these changes and modifications also fall within the scope of the present invention. For example, a person skilled in the art may appropriately add, delete, or change the design of each of the above-mentioned embodiments, or may add, omit, or change the conditions of a process. It is within the scope of the present invention as long as it has the following.

As explained above, the smoking device according to the present invention is a smoking device cartridge 1 that is used by being attached to an induction heating type smoking device 2, and includes a filling assembly that generates an aerosol when heated. 10, and a susceptor member 30 that is placed inside the filling assembly 10 and is heated by induction from the outside. Become.

Therefore, by using the susceptor member 30 in which magnetic wires 31 formed in a linear shape are bundled together in the smoking article cartridge 1, the number, type, diameter, etc. of the metal wires 31 can be changed to the type of the filler 20. Since the temperature can be adjusted according to the flavor and flavor, the temperature of the susceptor member 30 can be precisely set with a simple configuration.

Since the susceptor member 30 is formed in a helical bundle, it has a larger surface area than, for example, a cylindrical susceptor, and can accurately supply the induction heating magnetic field by the smoking tool 2.
Further, since the susceptor member 30 is formed into a rod shape, it can have a simpler configuration.

The mouthpiece 14 is disposed at the downstream end of the smoking article cartridge 1 and has a filter, and a sealing member 18 is disposed at the upstream end of the smoking article cartridge 1 and has a filter. Since the filter 18 includes a filter of a different color from the mouthpiece 14, the user can easily recognize the upstream side and the downstream side of the smoking article cartridge 1.

In each embodiment of the present invention, an example has been shown in which the smoking article cartridge 1 is provided with the support member 12, but the present invention is not limited to this. For example, the filling assembly 10 of the smoking article cartridge 1 is connected to the inner circumferential surface of the smoking article cartridge 1 so as to prevent the filling assembly 10 from moving toward the mouthpiece 14 even without the support member 12. 10, the support member 12 may not be provided.

Further, in the present embodiment, the susceptor member 30 is arranged at the center of the filling material assembly 10 when viewed in the radial direction, but it may be arranged outside the radial center of the filling material assembly 10, and a plurality of susceptor members 30 may be placed inside the packing assembly 10. In addition, in this embodiment, the susceptor member 30 is generally rod-shaped, but the susceptor member may be formed into a spirally wound shape or a cylindrical shape, and the susceptor member is positioned on the outside in the radial direction of the filling material assembly 10. You may also do so. In this way, when the susceptor member 30 is disposed outside the radial center of the filling material assembly 10, when a plurality of susceptor members 30 are used, or when the susceptor member 30 is spirally wound, the filling By positioning the susceptor member 30 outside the radial center of the filler assembly 10, the smoking article cartridge 1 allows a blade or pin that generates heat by being energized to be separately inserted into the radial center of the filler assembly 10. A possible configuration can be made.

Furthermore, as in the susceptor members 40 and 50 of FIGS. 5 and 6, the contact area with the filling material 20 is increased by changing the conventional flat plate shape to a non-flat shape, so that a wide area of the filling material 20 can be used. It becomes possible to heat it. Furthermore, in this case, since the heating efficiency is improved, the filling 20 can be sufficiently heated even if it is a single layer instead of forming multiple layers of multiple types of metals as in the past. It is possible to manufacture the susceptor members 40, 50 using a method that allows the manufacturing cost of the cartridge for a smoking article to be reduced. Here, although the susceptor member 40 in FIG. 5 has a twisted shape of a flat plate material, and the susceptor member 50 in FIG. 6 has a curved shape, similar effects can be obtained with other shapes.

Furthermore, the susceptor member 60 in FIG. 7 is a deformed piece of linear material. Even with such a shape, since the contact area with the filling 20 increases, it becomes possible to heat a wide range of the filling 20. Note that the susceptor member 60 has a shape obtained by deforming a linear material into a spiral shape.
