[0010] First Embodiment A first embodiment of the present invention will be described below with reference to the accompanying drawings. The present invention is not limited to the following embodiments. In the description of the drawings, the same elements are denoted by the same reference numerals. The dimensional ratios of the drawings are exaggerated for the sake of explanation. Actual ratios may differ.

[0011] (Overall configuration of a smoking article cartridge) A first embodiment of the present invention will be described in detail with reference to the drawings. 1 shows a cross-sectional view of a cartridge 1 for a smoking article having a filler accumulation 10 in As shown in the figure, the cartridge 1 for a smoking article is a substantially cylindrical filling material 20 filled with a large amount of the filling material. A packing material stack 10, a support member 12 through which airflow from the packing material stack 10 can pass, and A mouthpiece 14 having a mouthpiece 14a at one end and a sealing member 1 having an inlet 18a at the other end. 8 are arranged along the longitudinal direction and are integrated by being wrapped in a sheet-like packaging material 16. The packaging member 16 can be made of paper or the like.

[0012] In the first embodiment, the cartridge 1 for a smoking article has a diameter of 4.0 mm to 7.5 mm. Preferably, the thickness is 5.0 mm to 7.0 mm and the length is 40 mm to 80 mm. If the outer diameter of the cartridge 1 is set in the range of 6.5 to 7.5 mm, the The cartridge 1 for the smoking article is fitted with an appropriate force into the insertion portion 51 into which the cartridge 1 for the smoking article is inserted. The cartridge 1 for the smoking tool can be held in a suitable manner in the smoking tool 2. The length of the cartridge 1 for the smoking article is set to a range of 40 to 80 mm. When the cartridge 1 is inserted into the smoking article 2, the insertion portion 51 for receiving the smoking article cartridge 1 is inserted into the smoking article 2. Therefore, even if the cartridge 1 for the smoking device is inserted into the smoking device 2, the mouthpiece 14 a can be exposed from the smoking implement 2, and the length necessary for a smoker to smoke can be secured. become.

[0013] (Configuration of support member) The support member 12 prevents the packing material accumulation 10 from moving toward the support member 12 side and also prevents the packing material accumulation 10 from moving toward the support member 12 side. The airflow containing the aerosol generated in the packing mass 10 is circulated to the mouthpiece 14 side. The support member 12 is provided, for example, in a cylindrical and solid shape, and is filled so that its axial direction is along the central axis. The support member 12 is disposed between the packing mass 10 and the mouthpiece 14. The support member 12 may have an outer diameter of, for example, The diameter is 4.0mm to 7.5mm, and the length along the central axis is 50mm or less. The support member 12 may have dimensions different from those described above depending on the function and configuration as appropriate.

[0014] The support member 12 is made of a resin material. Examples of the resin material that forms the support member 12 include Examples include polypropylene, polylactic acid, and silicone. The material 12 may be other resin material, or wood or metal (aluminum, etc.) that has a greater cooling effect. The support member 12 may be formed of a material other than a resin material. The packing material accumulation 10 does not easily move toward the mouthpiece 14 (the packing material accumulation 10 In this case, if the support member 12 is fixed to the packaging member 16, the support member 12 may not be provided.

[0015] (Mouthpiece configuration) The mouthpiece 14 is formed in a cylindrical shape, for example, with a diameter of 4.0 mm to 7.5 mm and a center The length along the axis is formed to be 50 mm or more. The mouthpiece 14 is made of paper, for example. The mouthpiece 14 is formed by rolling up a sheet-like material made of paper, for example, into a cylindrical shape. It may be provided in a shape similar to that of a filter, or may include a cellulose acetate filter or the like to remove fine particles. The mouthpiece 14 may be configured to absorb the water vapor and aerosol generated in the packing material accumulation 10. It is a white filter that has the function of filtering out some of the fine particles. Since the article 20 is derived from a non-tobacco plant, the mouthpiece 14 is not necessarily required. .

[0016] (Configuration of packing aggregate) The packing material assembly 10 is a sheet-like packing material 20 bundled in the longitudinal direction. The filler 20 is formed into a substantially cylindrical shape by being wrapped in the wrapping member 25. The filler mass 10 is formed from tobacco plants or non-tobacco plants. The filler mass 10 is 10 to 25 mm long. The filler 20 is not limited to a long shape, but may be in the form of granules, dust, paste, or various other shapes. The cartridge 1 for the smoking article may have any other shape, such as a porous shape. The dimensions may be different from those stated above.

[0017] The outer diameter of the packing material assembly 10 is equal to the outer diameter of the support member 12 and the mouthpiece 14. The outer diameter is approximately constant along the central axis. A range of 0.5 mm is preferred, and a range of 5.0 mm to 7.0 mm is more preferred.

[0018] A susceptor 30 is provided inside the packing assembly 10. The susceptor 30 is a cylindrical The susceptor 30 has, for example, two metal wires 31, which are rod-shaped members. The placement will be explained in more detail later.

[0019] The metal wire 31 is made of a metal material containing a magnetic substance. The magnetic substance may be a ferromagnetic substance, a paramagnetic substance, or a Among magnetic materials, ferromagnetic materials move in the same direction as the external magnetic field when an external magnetic field is applied. It is a material that has strong magnetism in one direction and retains its strong magnetism even when the external magnetic field is zero. For example, ferromagnetic Iron, ferrite iron, ferrite powder, ferrite particles, ferrite-based ste Examples include stainless steel, ferromagnetic steel, stainless steel, nickel, and cobalt. The relative permeability of a material is much larger than 1. For example, iron has a relative permeability of about 5000. For Kel, it is about 600, for Cobalt it is about 250, and for Ferrite ste For non-linear applications, it is around 1000 to 1800.

[0020] Among magnetic materials, paramagnetic materials are weakly magnetized in the same direction as the external magnetic field when an external magnetic field is applied, It is a material that becomes non-magnetic when the external magnetic field is zero. For example, aluminum, platinum, The relative permeability of paramagnetic materials is slightly greater than 1, for example, For aluminum, it is about 1.000021, and for platinum, it is about 1.000265. and for manganese it is about 1.000830.

[0021] In addition, among magnetic materials, diamagnetic materials take on magnetism in the opposite direction to the external magnetic field when an external magnetic field is applied. It is a material that becomes non-magnetic when the external magnetic field is zero. For example, copper, graphite, and bimetal Examples of diamagnetic materials include aluminum and chromium. The relative permeability of diamagnetic materials is slightly less than 1. For example, copper is about 0.999990, and graphite is 0.99980 For bismuth, it is about 0.999834.

[0022] When an AC magnetic field is generated in a ferromagnetic material, not only does an induced current flow and generate Joule heat, However, heat (hysteresis loss) is generated by friction and vibration between molecules, so paramagnetic materials and Compared to diamagnetic materials, induction heating can be performed more easily, and the packing mass 10 can be heated sufficiently.

[0023] In addition, ferromagnetic materials have a high Curie temperature, for example, nickel has a Curie temperature of about 358°C. Therefore, even when the cartridge 1 for a smoking article is heated at a high temperature of, for example, 200°C, The temperature does not reach the Curie temperature, and the ferromagnetic properties are maintained. 10 can be heated stably.

[0024] The metal wire 31 is made of a ferromagnetic material such as iron, ferrite iron, or ferrite powder. ,Ferrite particles, ferritic stainless steel, ferromagnetic steel, stainless steel, nickel, edge For example, a ferrite-based steel sheet or a combination of these may be used. A combination of stainless steel and nickel is preferred, and iron, chromium, aluminum are more preferred. It is an alloy (iron chromium aluminum alloy) that combines aluminum and iron.

[0025] Here, we will explain the relationship between temperature and magnetism of iron and chromium. Iron is a ferromagnetic material. The Curie temperature, which is the temperature at which chromium changes from a ferrodiamagnetic to a paramagnetic state, is about 770°C. The Neel temperature, which is the temperature at which it changes to its hydroxyl group, is approximately 308°C.

[0026] The metal wire 31 may also 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 magnetic material is used. For example, nickel alloy or nickel-iron alloy may be used. However, the ferromagnetic material is inductively heated, so that the packing assembly 10 can be heated sufficiently. Instead of the magnetic material, a metal material containing a paramagnetic material and a diamagnetic material may be used. However, induction heating is possible in this case. It is preferable to use a metal material containing a magnetic substance.

[0027] Similarly, the susceptor 30 is combined with a metal wire 31 made of a ferromagnetic material, a paramagnetic material, or a diamagnetic material. For example, a metal wire 31 made of nickel, which is a ferromagnetic material, and a ferromagnetic The metal wire 31 is made of iron, which is the material of the body, and is physically attached to the metal wire 31. and a metal wire 31 made of aluminum, a paramagnetic material, which is physically attached to the , or covering the outer surface of the metal wire 31 with the metal wire 31 .

[0028] (Configuration of sealing member) The sealing member 18 is formed in a cylindrical shape, for example, with a diameter of 4.0 mm to 7.5 mm and a central axis The length along the seal member 18 is 30 to 70 mm. Similarly, a sheet-like member made of paper may be rolled up and provided in a cylindrical shape. The member 18 passes air from the inlet portion 18a, i.e., the upstream side, toward the packing accumulation 10. The sealing member 18 also functions to prevent the steam generated in the packing accumulation 10 and Of the aerosols, the remaining liquid that remains in the packing material accumulation 10 and liquefies can be absorbed. The seal member 18 may be made a different color (e.g., black) from the mouthpiece 14, so that the The upstream and downstream sides of the smoking device cartridge 1 can be easily determined.

[0029] (Usage of smoking cartridges) FIG. 2 shows a cross-sectional view of the cartridge 1 for a smoking article, illustrating how it is used. The cartridge 1 is used by attaching the sealing member 18 side to the smoking article 2. The smoking device 2 has an insertion part 51 into which the smoking device cartridge 1 is inserted. The induction heating unit 52 is provided along the line . The induction heating unit 52 includes an induction coil. The metal wire 31 of the susceptor 30 included in the packing assembly 10 inserted into the insertion portion 51 The susceptor 30 can be heated by inductive coupling. The surrounding filling material 20 is heated, and an aerosol can be generated. The person inhales through the mouthpiece 14, thereby inhaling the airflow containing the aerosol. do.

[0030] Furthermore, the smoking article 2 can detect the temperature of the susceptor 30. Specific examples include: The induction heating unit 52 heats the susceptor 30 by the magnetic force applied to the metal wire 31, while The DC power supply voltage of the DC power supply supplied to the induction heating unit 52 and and the apparent ohmic resistance of the susceptor 30, determined from the DC current drawn from the DC power supply. By detecting the resistance, the resistance value of the susceptor 30 at the time of detection can be detected. That is, when the metal wire 31 is made of an iron-chromium-aluminum alloy, the magnetism of chromium becomes diamagnetic at 308°C. At 770°C, the magnetic properties of iron change from ferromagnetic to paramagnetic. Based on the apparent ohmic resistance of the metal wire 31, the temperature of the susceptor 30 is set to less than 308°C. It can detect whether the temperature is between 308°C and 770°C, or between 308°C and 770°C, or 770°C or higher.

[0031] (Filling composition) Filler 20 is a dried and crushed non-tobacco plant that generates an aerosol. Formers, microcrystalline cellulose, flavor additives, preservatives, adhesives or thickeners, etc. The mixture is mixed, formed into a sheet, and then cut to a predetermined width and length. The filler 20 is not limited to a long shape, and may have various shapes. For example, it may be formed into a paste or granules.

[0032] When the filler 20 is configured in a long shape, the cross section perpendicular to the central axis is approximately rectangular. The ratio of the long side to the short side of the cross section is preferably in the range of, for example, 1:1 to 30:1. The length is preferably in the range of 0.1 mm to 7.5 mm, more preferably 0.1 mm to The length of the short side is preferably in the range of 0.1 mm to 1.0 mm, and more preferably in the range of 0.1 mm to 1.0 mm. More preferably, the length of the filler 20 is in the range of 0.1 mm to 0.5 mm. It is preferable that the length of the packing 20 is approximately the same as that of the aggregate 10. The length of the packing 20 is 10 mm to 25 mm. The range is preferably 10 mm to 20 mm, and more preferably 10 mm to 20 mm. An example of the dimensions of the object 20 is 1.5 mm long, 0.3 mm short, and 12 mm long. is.

[0033] Next, specific examples of the raw materials used as the filler 20 will be described. It consists of any one or more combinations of the ingredients listed below.

[0034] The filler 20 may be derived from tobacco or non-tobacco plants. Examples of non-tobacco plants include baco leaves, tobacco stems, expanded tobacco, and homogenized tobacco. Plants other than tobacco plants are also included. Preferred parts of non-tobacco plants include leaves, flesh, Seeds, roots (scaly roots, tubers, etc.), stems, tubers, skins (stem bark, bark, etc.), flowers (petals, stamens, pistils, etc.) , trunks, branches, etc.

[0035] In this specification, "plants" refers to a group of plants, such as grass and trees, as opposed to animals. In addition to organisms that have roots and live in fixed locations, there are also organisms such as microalgae and seaweed. This also includes algae, mushrooms, and other fungi.

[0036] The filler 20 may be, for example, a dried and crushed non-tobacco plant material that is filled with an aerosol-generating air. Aerosol formers, microcrystalline cellulose, additives to add flavor, preservatives, binders or thickeners Mix with adhesives etc. as needed, crush or classify to make powder or granules, or mold into a paste. The aerosol-forming substrate 23 is formed into a sheet shape and then cut to a predetermined width and length. The material is cut into strips or rods so as to have a desired thickness.

[0037] For example, when the non-tobacco plant part is a leaf, tea can be preferably used. Not only do different plants produce different teas, but even the same plant can produce different teas depending on how it is processed. Specifically, for example, Japanese tea, black tea, Angelica keiskei tea, sweet tea, Gynostemma tea, aloe tea, Ginkgo leaf tea, oolong tea, turmeric tea, salicylic acid tea, Eleuthero tea, plantain tea, Kiodoshi tea, persimmon leaf tea, chamomile tea, chamomile tea, Kawara Ketsumei tea, quince tea, chrysanthemum tea, Gymnema tea, guava tea, wolfberry tea, soft leaf tea, black bean tea, gennoshoko tea, brown rice tea, burdock Tea, comfrey tea, bifu tea, cherry blossom tea, saffron tea, shiitake tea, shiso tea, jasmine tea, Ginger tea, horsetail tea, lily of the valley tea, Swertia japonica tea, buckwheat tea, elm tea, dandelion tea, sweet Tea, Houttuynia cordata tea, Eucommia tea, Sword bean tea, Elderberry tea, Licorice tea, Job's tears tea, Habu tea , Loquat leaf tea, Pu'er tea, Safflower tea, Pine needle tea, Mate tea, Barley tea, Megusurinoki tea, Mugwort tea These teas include eucalyptus tea, monk fruit tea, rooibos tea, and bitter melon tea. You can use used tea leaves after drinking. If you use used tea leaves, you can reuse expensive tea. It can be used effectively.

[0038] Furthermore, extracts of non-tobacco plants, so-called extracts and processed products, can also be used. The extract may be in the form of liquid, syrup, powder, granules, solution, etc.

[0039] The aerosol former used as the raw material for the filler 20 is glycerin, propylene glycol, , sorbitol, triethylene glycol, lactic acid, diacetin (glycerin diacetate) ), triacetin (glycerin triacetate), triethylene glycol diacetate , Triethyl citrate, Isopropyl myristate, Methyl stearate, Dodecanedio dimethyl phosphate, dimethyl tetradecanedione, etc. Phosphorus and propylene glycol are preferred.

[0040] Microcrystalline cellulose as a raw material for the filler 20 is, for example, microcrystalline cellulose obtained from the pulp of fibrous plants. It is obtained by partially depolymerizing α-cellulose with acid, and The soluble portion is removed from the base, and the insoluble portion is crystallized as appropriate.

[0041] The microcrystalline cellulose may be in the form of powder or may be dispersed in a solvent such as water to form a suspension. In this case, a high-speed stirrer or a high-pressure homogenizer can be used to disperse the material in the solvent.

[0042] Furthermore, if necessary, a flavor additive may be preferably used as an ingredient of the filling 20 to add flavor. Flavoring additives include mint, cocoa, coffee, black tea extract, and tea extract. Preservatives that are used in food are preferred, for example, , sorbic acid, potassium sorbate, benzoic acid, sodium benzoate, etc.

[0043] The filler 20 contains menthol and a water-insoluble cross-linked polymer (preferably polyvinyl polyimide). lolidone) may be included. Combining menthol with a water-insoluble cross-linked polymer This effectively prevents menthol from sublimating, allowing the menthol flavor to be maintained for a long period of time. Here, menthol is not limited to that obtained from natural products, but may also be a synthetic product. Peppermint, mint, peppermint oil, and other menthol-containing ingredients may also be used.

[0044] The flavor additive may be added to the mouthpiece 14 by, for example, impregnating the walls of the mouthpiece 14. The flavor additive is provided in the mouthpiece 14. The present invention is not limited to such an embodiment, and may be embodied, for example, by placing a capsule containing the flavor additive in a mouthpiece. The flavor additive is provided in the mouthpiece 14 by being embedded in the wall of the mouthpiece 14. Alternatively, a flavor additive may be provided between the mouthpiece 14 and the packing material assembly 20. The flavor additive may be encapsulated in a capsule. If the capsule is broken, the smoker can destroy it by pressing it with his fingers. This makes it possible to volatilize the aromatic components of the flavor additive at a desired timing.

[0045] Furthermore, the flavor additive may be, for example, encapsulated in a microcapsule. The microcapsules may be provided in the packing assembly 10. may be provided on the support member 12.

[0046] Examples of binders or thickeners used as raw materials for the filling 20 include guar gum and xanthan gum. gums such as gum arabic and locust bean gum, e.g., hydroxypropylcellulose; cellulose, carboxymethyl cellulose, hydroxyethyl cellulose, methyl cellulose cellulose binders such as starch, alginic acid, etc. Organic acids, sodium alginate, sodium carboxymethylcellulose, caramel, Polysaccharides such as conjugate base salts of organic acids such as agar and pectin, and combinations thereof Examples include:

[0047] (Filling manufacturing process) The manufacturing process of the filling material 20 involves drying and grinding the main raw material, tobacco plants or non-tobacco plants. The drying and crushing process involves pre-processing, weighing, etc. of other raw materials, and the preparation process involves pre-processing, weighing, etc. of other raw materials. The method includes a mixing step of mixing ingredients to form a composition, and a filling molding step of molding the composition.

[0048] In the drying and grinding process, the main raw material, tobacco plant or non-tobacco plant parts (e.g. (e.g., leaves, seeds, dried fruits, stems, bark, roots, etc.) are processed into a specified crushed material to make a composition. At that time, the aerosol former, water, and other components that will be added later will be absorbed or supported. It is preferable to adjust the moisture content to a level that is convenient for drying. By setting the temperature in this range, it is possible to avoid the scattering of the necessary flavor components while maintaining the desired flavor. It is easy to achieve the desired moisture content. Furthermore, the drying and grinding process includes a sieving process to sift the ground material. It is also possible to provide a powder with a desired particle size and then add it to the mixing step.

[0049] In the preparation step, the raw materials necessary for producing the filling 20 can be prepared. The microcrystalline cellulose is weighed in the preparation step and then added to the mixing step.

[0050] In the mixing step, a conventional mixer can be used. For example, A preferred mixing method is to mix the ingredients while applying shear force with a stirring blade.

[0051] In the filling molding process, the composition of the various raw materials is formed into a thin sheet, which is then cut. By cutting, strip-shaped or rod-shaped fillers 20 are formed. To achieve this, multiple roll mills are used. Compression caused by being pressed between the rolls and shearing caused by the difference in roll speeds results in kneading and dispersion. While performing the above steps, it is possible to form a sheet of the desired thickness using a doctor blade. It is also possible to prepare the film by using a press roller or a press machine.

[0052] To prepare the powder or granular filler 20, the above composition is crushed or pulverized as appropriate. It is preferable to classify the powder or granular filler 20. The average particle size of the powder or granular filler 20 is, for example, It is preferably 0.1 to 3.0 mm, and more preferably 0.5 mm or less. The average particle size can be determined, for example, by the sieving method described in JIS K 0069:1992. In other words, this average particle size is calculated based on the test results using multiple sieves. The diameter is calculated by adding up the mass from the larger one and then measuring 50% of that mass. The particle size at 50% of the cumulative value in the particle size distribution obtained by the laser diffraction and scattering method was taken as the average particle size. You can do that.

[0053] In the filling molding process, the composition is forced through an orifice under pressure to form a shape similar to other processes. In the filling forming step, non-tobacco plants, aerobic plants, etc. may be used as needed. Solformer, binder or thickener, flavor additive, preservative, etc. may be further added. Water or the like may be added.

[0054] The thickness of the sheet obtained in the filling molding step is preferably in the range of 0.1 mm to 1.0 mm. The thickness is preferably in the range of 0.1 mm to 0.5 mm. The sheet is then cut to a predetermined width using a rotary cutter or the like.

[0055] Here, when the surface of the filler 20 is to be made sticky, any means capable of making the surface sticky can be used. Although there is no particular limitation, it is sufficient if the above-mentioned binder is attached to at least a part of the surface. By adding the filling material, a strip-shaped or rod-shaped filling material 20 and a powder-shaped, granular or paste-shaped filling material 2 When combined with the filler 20, powder, granules or paper are applied to the surface of the strip or rod-shaped filler 20. The filler 20 in a staggered shape can be stably held.

[0056] (Susceptor shape and arrangement) 3 shows a cross-sectional view of section II in FIG. 1. As shown in FIG. 3, the metal wire 31 is The susceptor 30 is formed in the shape of a long, thin rod. The metal wires 31 are made of a chromium aluminum alloy and are spaced apart by a predetermined distance.

[0057] The ratio of the length of the susceptor 30 in the longitudinal direction to the total length of the packing assembly 10 is That is, the susceptor 30 has a length that is the entire length of the packing assembly 10. is doing.

[0058] The susceptor 30 does not have to extend over the entire length of the packing assembly 10, but may extend in the longitudinal direction. The length of the packing assembly 10 is 25% or more and 100% or less of the total length of the packing assembly 10. In the first embodiment, all of the metal wires 31 are made of iron chromium aluminum. Although it was explained as an alloy, the susceptor is made of multiple metal wires, some of which are ferromagnetic and some of which are paramagnetic. Even if you combine multiple types of magnetic materials, such as using magnetic materials and diamagnetic materials, The number of metal wires 31 may be two or three or more. The metal wires 31 may be welded together by adhesive or welding material, and the metal wires 31 may be thermally welded together. Alternatively, it is sufficient if they can be electrically connected.

[0059] As shown in FIG. 3, the susceptor 30 is disposed at approximately the center of the packing assembly 10 in the radial direction. Specifically, the distance L1 from one metal wire 31 to the covering member 25, 1 to the other metal wire 31, and the distance L2 from the other metal wire 31 to the containing member 25. L3 are all approximately the same, and the midpoint P between one metal wire 31 and the other metal wire 31 is full. This is approximately the center of the packing material stack 10. As a result, the packing material stack 10 is such that the entire packing material 20 is The packing material accumulation 10 is heated uniformly and evenly from the center in the radial direction, and the air is efficiently Aerosols can be generated.

[0060] Here, the distances L1, L2, and L3 have been described as being approximately equal. The difference is within a maximum range of 50% (first range). Although the description has been given of the structure in which the nozzle 10 is positioned approximately at the center of the body 10, the nozzle 10 may be positioned within a range of 1 / 3 of the diameter R of the enclosing member 25 (the third Therefore, the metal wire 31 is required to be within the distance L1 ( L3) is 1 / 6 or more of the diameter R1 of the containing member 25, so that the metal wire 31 and the containing member 25 and the heat generated from the metal wire 31 is prevented from contacting the containing member 25 and the In addition, the intermediate point P is a filler accumulation point. Since the metal wire 31 is positioned within the second range of the body 10, it is possible to prevent the metal wire 31 from being biased to one part. It is possible.

[0061] (Method of manufacturing a packing body) Referring to FIG. 4, an explanatory diagram for explaining a method for manufacturing the packing assembly 10 is shown. The manufacturing method of the packing material stack 10 is roughly divided into the above-mentioned packing material forming process (not shown), the converging process, The process includes a step S1, an inclusion step S2, and a cutting step S3.

[0062] In the converging step S1, the extending filler 20A after the above-described filler forming step is The wires are converged to fit the diameter of the assembly 10. In this converging step S1, the extending metal wires 31 A is positioned so as to be disposed at a predetermined position, and extends along the metal wire 31A. While disposing the filler 20A, the metal wire 31A is covered with the filler 20A and converged.

[0063] In the enclosing step S2, the packing 20B converged in the converging step S1 is encircled by an extending enclosing member 25B and forms an extending packing mass 10C. Then, in the cutting step S3, the elongated packing aggregate 10 produced in the enclosing step S2 is cut. C is cut to a predetermined length (10 to 25 mm) using, for example, a roller cutter (not shown), A packing mass 10 is formed.

[0064] Therefore, by using a plurality of metal wires 31 (for example, two wires), the volume of a single metal wire can be reduced. Compared to using metal wires, the diameter per wire can be made smaller, so the cutting process The force required to cut the extending packing accumulation 10C in S3 is reduced, and This reduces wear on the cutter.

[0065] Referring to FIG. 5, a cartridge for a smoking article is filled with powder or granular filler. The following is an explanatory diagram for explaining the manufacturing method of the edge 101. The packed material (hereinafter referred to as packing material 120 to distinguish it from the packing material 20 formed in a sheet shape) Smoking article cartridge 101 (hereinafter referred to as smoking article cartridge filled with filler 20) Regarding the manufacturing method of the cartridge for smoking articles (referred to as cartridge 101 to distinguish it from cartridge 1), I will explain.

[0066] The manufacturing method of the cartridge 101 for a smoking article includes a process of disposing a partition member (not shown), a process of filling a filler, and Step S11, susceptor filling step S12, lid attachment step S13, and filter attachment step (not shown) First, in the partition member disposing step, cardboard (for example, 0.3 to 1.5 mm thick) is used. The partition wall member 112 is disposed inside the framework member 116 formed into a cylindrical shape (approximately 0.7 mm). Next, in the filler filling step S11, the filler 1 is poured from the upstream end of the framework member 116. Fill 20.

[0067] Next, in the susceptor filling step S12, the filler material filled in the framework member 116 in the filler filling step S11 is Two metal wires 31 are inserted into the filler 120. At this time, the upstream end of the framework member 116 A predetermined space C is formed between the portion and the filler 120. This space C is The outer shape of the seal member 18 is, for example, 4.0 mm to 7.5 mm in diameter and 4.0 mm to 7.5 mm in length along the central axis. The length of the space is 30 to 70 mm.

[0068] Next, in the lid attachment step S13, the inner periphery of the framework member 116 is attached to cover the upstream side of the filler 120. The cover member 118 is attached to the portion. Here, the cover member 118 has a thickness of 0.01 to 0.60 mm. It is a paper member having breathability of 0.03 to 0.10 mm. Preferably, the thickness is 0.03 to 0.10 mm. This is because the function as a lid is ensured while the breathability and manufacturability are favorable. In the filter mounting step, the filter 14 is inserted into the downstream end of the framework member 116. In the attachment and packaging process, the radial periphery of the frame member 116 is wrapped with label paper (not shown). Optionally, a capsule containing a sealed fragrance ingredient may be inserted before inserting the filter 14. The order of the steps may be changed as appropriate.

[0069] Here, in the lid attachment step S13, the lid member 118 is attached to the bone so as to cover the upstream side of the filler 120. The cover member 118 is attached to the upstream end of the frame member 116. In this case, the filler 120 may be attached to the skeleton so as to secure the space C. It is preferable to fix the cover member 118 to the cover member 116 using, for example, an adhesive. By attaching the cartridge 101 for the smoking article, the filling material heated by the susceptor 30 is The powder generated from the filler 120 (for example, the soot-like powder generated by heating) is It is possible to prevent the cover member 118 from falling into the insertion portion 51. By attaching the cover member 118 to the upstream end of the filler 120, the cover member 118 is spaced apart from the filler 120 by the space C. However, it is possible to prevent the substrate from being heated by the susceptor 30.

[0070] The cartridge 101 for a smoking article manufactured by such a manufacturing method is in powder or granular form. The filler 120 is arranged upstream of the cartridge 101 for the smoking article, and the space The filler 120 and the metal wire 31 can be positioned downstream by the length C.

[0071] As described above, in the smoking device according to the first embodiment, the filler 120 is packed in a packaging material A certain distance corresponding to the space C is provided from one end side of the packaging member 116, and the inside of the one end of the packaging member 116 The one end side of the packaging member 116, the inner circumferential side of the packaging member 116, and the upstream end of the filler 120 are The space C is formed by the cover member 118 corresponding to the above, so that the packing assembly 10 can be guided. It can be positioned at a position corresponding to the heating unit 52.

[0072] Referring to FIG. 6, a cartridge for a smoking article is filled with a paste-like filler. An explanatory diagram for explaining the manufacturing method of 201 is shown below. The material (hereinafter referred to as the filler 220 to distinguish it from the sheet-shaped filler 20) is filled. The loaded smoking article cartridge 201 (hereinafter referred to as the smoking article cartridge filled with the filler 20) A method for manufacturing a cartridge for a smoking article (hereinafter referred to as a cartridge 201 to distinguish it from the cartridge 1) will be described. do.

[0073] The manufacturing method of the cartridge 201 for smoking articles includes a susceptor mounting step S21, a frame member mounting step S22, and a Step S22, filling step S23, a drying step (not shown), and a filter installation step (not shown) The filter attachment process and packaging process are conducted by a smoking Since the manufacturing method is the same as that of the tool cartridge 101, the description here will be omitted. Omitted.

[0074] First, in the susceptor mounting step S21, two metal wires 31 are inserted into the jig 241. The jig 241 has a diameter similar to the outer shape of the seal member 18 of the cartridge 1 for a smoking article. A cylindrical protrusion 241 with a diameter of 4.0 mm to 7.5 mm and a length along the central axis of 30 to 70 mm a is formed on the base. By fitting the protrusion 241a to the upstream end of the skeletal member 116, the skeletal member 116 The jig 241 is also provided with a susceptor mounting hole 241b. Specifically, the susceptor mounting hole 241b is formed so that the frame member 116 is fitted onto the protrusion 241a. When they are joined together, the metal wire 31, i.e., the susceptor 30 in the cartridge 1 for the smoking article is located at the same position. That is, it is a hole capable of supporting a metal wire 31 so that the susceptor 30 is positioned therein.

[0075] Next, in the frame member mounting step S22, the upstream end of the frame member 116 is attached to the protrusion of the jig 241. By fitting 241a, the framework member 116 is attached to the jig 241 and supported. In the filler filling step S23, the filler 24 is poured from the downstream end of the framework member 116 through the filling nozzle. 3 is inserted and filled with the filling material formed into a paste.

[0076] Next, in the drying step, the filler 2 filled in the framework member 116 in the filler filling step S23 is 20 is heated and dried at 30 to 50°C. As a result, the filling material formed into a paste form is obtained. The moisture inside evaporates and the porous filler 220 is formed.

[0077] The cartridge 201 for a smoking article manufactured by this manufacturing method is formed into a paste-like substance. The filler 220 to be formed is disposed on the upstream side of the cartridge 201 for the smoking article, and the space C is The filler 220 and the metal wire 31 can be positioned downstream by the length.

[0078] In addition, the above-mentioned framework member mounting step S22, filler filling step S23 and filler filling step S24 are Instead of step S23, a porous filler is inserted into one end of the framework member 116. The jig 241 is then fitted to the downstream end of the frame member 116, and the frame member 116 is then fitted to the protrusion 241a of the jig 241. The downstream end of the nozzle 16 is pressed against the nozzle 16 to adjust the position of the filler, and the metal wire 31 is inserted. By adopting such a process, it is not necessary to use the jig 241 during the drying process. This eliminates the need for additional equipment and reduces facility costs.

[0079] Second Embodiment Referring to FIG. 7, a cartridge for a smoking article having a filler accumulation according to a second embodiment is shown. 7 shows a cross-sectional view of the cartridge for a smoking article according to the second embodiment. The following mainly describes the differences from the first embodiment, and the same applies to both the first and second embodiments. The explanation of the points of passage will be omitted here.

[0080] In the second embodiment, the packing material accumulation 310 is formed by stacking the packing material 320 and the packing member 325 upstream. The side end portion of the susceptor 30 extends to the upstream end portion of the packaging member 16. This is the same position as the packing material accumulation body 10 in the embodiment. In the first embodiment, a cover member 318 equivalent to the cover member 118 is used instead of the seal member 18. It is set up as follows.

[0081] Therefore, the packing accumulation 310 in the second embodiment is the same as the packing accumulation 310 in the first embodiment. The filler 320 and the containing member 325 are extended to a position corresponding to the seal member 18. Without providing a separate cooling member 18, the cooling member 18 is at least the same as the packing 20 in the first embodiment.
