Description

[Technical Field]

[0001] The present invention relates to a cylindrical cartridge for a smoking article and a method for manufacturing a cylindrical cartridge for a smoking article. [Background technology]

[0002] In recent years, in response to the trend toward smoking cessation, electronic cigarette products have become popular, allowing users to enjoy tobacco without using a flame by heating a cylindrical cartridge containing tobacco components and inhaling the vaporized tobacco components. The structure of such a cartridge includes, for example, a filter element, a substrate with a filler containing tobacco components, a support member disposed between the filter element and the substrate to support the substrate, and an exterior sheet that wraps the components flat into a single cylindrical shape and adheres and fixes the longitudinal end portions with glue or the like (see Patent Document 1).

[0003] When a user uses the cartridge, the substrate is inserted into the insertion portion of the electronic cigarette body, and the substrate is heated by a heating element located in the center of the bottom of the insertion portion, generating an aerosol from the filler. When the user inhales the aerosol from the filter member side, the tobacco components are delivered to the user's mouth (see Patent Document 1, Figure 4). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2019-000094 Summary of the Invention [Problem to be solved by the invention]

[0005] However, when a user inserts a cartridge into the electronic cigarette body, the cartridge is subjected to bending and twisting forces, making flat-wound cartridges in which the overlapping glued portions are in a straight line in the longitudinal direction weak against bending and can peel or tear.

[0006] Furthermore, when packaging cartridges with exterior sheets, it was difficult to roll flat without gaps due to differences in the rigidity, hardness, strength, and other attributes of each component and substrate, as well as their outer diameters, which sometimes resulted in gaps due to longitudinal misalignment of the components and substrates.Gaps not only reduce the quality of the cigarette body, but also affect productivity and strength, so multiple processes were required, such as wrapping each component and substrate with an exterior sheet.

[0007] The present invention has been made in consideration of the above circumstances, and its object is to provide a cylindrical cartridge for a smoking device, which improves the strength of the entire cartridge, is less likely to cause misalignment of components during the manufacturing process, and which reduces the number of manufacturing steps while maintaining the quality of the cigarette body, and a method for manufacturing the same.

[0012] Hereinafter, a mode for carrying out the present invention (hereinafter referred to as an embodiment) will be described in detail with reference to the drawings. In the description of the drawings, the same elements are given the same reference numerals, and duplicate explanations will be omitted. Furthermore, the dimensional ratios in the drawings are merely examples and are not intended to be limiting. Furthermore, for the convenience of explanation, some parts may be exaggerated.

[0013] Furthermore, in this specification, "smoking" generally often means inhaling smoke containing nicotine, tar, etc., which is produced by burning or heating tobacco leaves of the Nicotiana genus of the Solanaceae family or materials containing tobacco components, but here it simply means "enjoying smoke," "tasting smoke," or "enjoying smoke," and the aromatic components that form the source of smoke are not limited to tobacco materials, but also apply to those that use non-tobacco materials.

[0014] As shown in Figures 1 to 6, in one embodiment of the present invention, a cylindrical cartridge 1 for a smoking article includes a filter member 13, a substrate 10 containing a filler 21, a transfer section 11 provided between the substrate 10, the filter member 13, and an exterior sheet 22.

[0015] Fig. 1 is a cross-sectional view showing an example of the structure of a cylindrical cartridge 1 for a smoking article. The cartridge 1 shown in Fig. 1 includes a substrate 10 containing a filler 21, a filter member 13, and a transfer section 11 provided between the filter member 13 and the substrate 10, and has a cylindrical appearance. It may also include a cover member 14 at the end of the substrate 10 containing the filler 21. The direction in which the three elements of the substrate 10, the transfer section 11, and the filter member 13 are arranged adjacent to each other is defined as the longitudinal direction (X direction) of the cartridge 1.

[0016] Fig. 2 is an external view showing an example of the structure of the cartridge 1 of the present invention. As shown in Fig. 2, the exterior sheet 22 is wound spirally in a direction inclined with respect to the longitudinal direction of the cartridge 1. By winding the exterior sheet 22 spirally, the strength of the cartridge 1 against bending is improved.

[0017] The transfer section 11 is arranged adjacent to the base material 10. There are no particular limitations on the material of the transfer section 11 as long as it has excellent heat resistance, and it can be made of, for example, silicone. The length of the transfer section 11 is preferably 10% to 40% of the total length of the cartridge 1, and more preferably 15% to 30%.

[0018] 3 is a cross-sectional view showing another embodiment of the structure of a columnar cartridge for a smoking article. Cartridge 1 includes a substrate 10 containing a filler 21, a support 12 that supports the filler 21, a filter member 13, a transfer section 11 provided between the support 12 and substrate 10, and an exterior sheet 22, and has a columnar appearance.

[0019] The substrate 10, support 12, transfer part 11, and filter member 13 are packaged in an exterior sheet 22. The longitudinal direction of the cartridge 1 and the longitudinal direction of the substrate 10 are, for example, parallel to each other. Furthermore, by providing the support 12, the aerosol airflow is stabilized, making it easier for the user to inhale the aromatic components.

[0020] The transfer part 11 may be formed of a commonly used support member 15 that supports the substrate 10 containing the filler 21. Furthermore, since the cartridge 1 has improved strength against bending, the transfer part 11 may be formed of a sponge, a foam, a fiber aggregate, a porous body, or a rod-like material that does not contact the inner surface of the outer shell of the cartridge 1 (see FIG. 1).

[0021] An airflow hole may be provided in the center of the transfer section 11. The presence of the hole allows the aerosol generated in the substrate 10 to pass through the airflow hole and flow efficiently toward the filter member 13. It is also possible to configure the transfer section 11 so that it has an airflow hole or a notch on the side.

[0022] The exterior sheets 22 have overlapping portions 30 between the exterior sheets 22 and non-overlapping portions 31, and the overlapping portions 30 may be configured to extend in a direction inclined with respect to the longitudinal direction of the cartridge 1.

[0023] 4 and 5 are diagrams showing an example of the filler 21 (filled state) in the substrate 10. The substrate 10 includes the filler 21 filled in an exterior sheet 22. The exterior sheet 22 has overlapping portions 30 and non-overlapping portions 31 between the exterior sheets 22, and the overlapping portions 30 extend in a direction oblique to the longitudinal direction of the cartridge 1. The exterior sheet 22 that covers the filler 21 covers the substrate 10, the support 12, the transfer unit 11, and the filter member 13. However, the filler 21 may be covered with another exterior sheet 22, and the substrate 10 may be configured to include a cylindrical exterior unit 20 (see FIG. 6) and the filler 21. This configuration improves the force that holds the filler 21 in the cartridge 1.

[0024] In the exterior sheet 22, the overlapping portion 30 extending in a direction oblique to the longitudinal direction can be configured, for example, by preparing a parallelogram-shaped exterior sheet 22, rolling it into a cylindrical shape, and gluing both end portions to form a single loop, thereby configuring the glued portion as the overlapping portion 30. The exterior sheet 22 has overlapping portions 30 between the exterior sheets 22 and non-overlapping portions 31, and the overlapping portions 30 extend in a direction oblique to the longitudinal direction of the cartridge 1, which makes it possible to provide a glued portion extending in the circumferential direction on the exterior sheet 22 of the cartridge 1, thereby dispersing the force of twisting or bending the cartridge 1 by the user and improving the strength of the entire cartridge 1.

[0025] 6, the overlapping portion 30 may be formed by preparing a tape-like exterior sheet 22 and spirally winding it so that it overlaps with the tape-like exterior sheet 22 to form a columnar structure. By forming the overlapping portion 30 in a spiral shape, a spiral step can be provided on the inner peripheral surface of the exterior sheet 22. This step creates a smooth airflow of the aerosol, improving the smoking taste and flavor and increasing the efficiency of exhalation.

[0026] Furthermore, as shown in Fig. 7, a configuration may be adopted in which multiple parallelogram-shaped sheets are bonded together with only their sides overlapping to form exterior sheet 22, and then exterior sheet 22 is rolled up flat as shown in Fig. 7. By adopting such a configuration, the strength of the exterior of cartridge 1 can be improved without changing the flat-rolling production process.

[0027] The range of the overlapping portion 30 is preferably smaller than the range of the non-overlapping portion 31. Here, the range of the overlapping portion 30 refers to the shortest distance between the edge of the exterior sheet 22 that constitutes the non-overlapping portion 31 and the edge of the exterior sheet 22 that constitutes the overlapping portion 30. Similarly, the range of the non-overlapping portion 31 refers to the value obtained by subtracting the range of the overlapping portion 30 from the pitch p (see Figure 6). In the case of a spiral shape with multiple overlapping portions 30, the range is the arithmetic mean value of the overlapping portions 30. By making the range of the overlapping portion 30 smaller than the range of the non-overlapping portion 31, the amount of exterior sheet 22 used can be minimized. Furthermore, the ratio of the range of the overlapping portion 30 to the non-overlapping portion 31 is preferably 7% or more and less than 40%, more preferably 4% or more and less than 30%, and even more preferably 5% or more and less than 25%. Note that the ratio of the range of the overlapping portion 30 When the overlapping portion 30 and the non-overlapping portion are the same or the non-overlapping portion is larger than the overlapping portion 30, the strength is improved due to the increased overlapping portion.

[0028] The exterior sheet 22 is not particularly limited as long as it is a commonly used material, and can be made of, for example, a heat-conducting material such as film or foil paper, a heat-insulating material, thick paper, plug wrap, cigarette paper, tobacco paper, or any combination thereof.

[0029] A fragrant material may be applied to or impregnated into the inner peripheral surface of the exterior sheet 22. There are no particular limitations on the fragrant material as long as it is one that is generally used in a cylindrical cartridge 1 for a smoking device, and examples thereof include tobacco extract, vanillin, chocolate, cocoa, menthol, etc.

[0030] The thickness of the exterior sheet 22 is preferably 0.05 mm to 0.5 mm, more preferably 0.06 mm to 0.4 mm, and even more preferably 0.1 mm to 0.2 mm. By setting the thickness within the above range, it becomes easier to form the overlap portion 30 (or the first overlap portion 41 described below) extending in a direction inclined relative to the longitudinal direction.

[0031] The average outer diameter d of the exterior part 20 (see FIG. 6) or the average outer diameter d of the cartridge 1 in which the exterior sheet 22 is wound spirally in a direction inclined relative to the longitudinal direction is preferably 5.0 mm or more and 8.0 mm or less from the viewpoint of ease of holding by the user. Note that, in the cartridge 1, the "outer diameter" means the diameter when the cross section is a perfect circle, and the length of the major axis when the cross section is an ellipse. Furthermore, in this specification, even if the cross section perpendicular to the longitudinal direction is polygonal, it is still a cartridge 1, and the "outer diameter" is defined as the diameter of the circumscribing circle with the largest diameter among one or more circles circumscribing the polygon.

[0032] The overlapping portions 30 preferably have a pitch p of 5% to 97% of the total length in the longitudinal direction, and more preferably 7% to 55%. If the pitch p is less than 10% of the total length of the cartridge 1, the overlapping portions 30 will be narrower, reducing the adhesive surface and reducing productivity, and the exterior surface of the cartridge 1 will have more inclined lines, resulting in more bending points. On the other hand, if the pitch p exceeds 55%, it will be difficult to arrange the members and base material 10 that make up the cartridge 1 without gaps, and the extended overlapping portions 30 will reduce the overall strength.

[0033] Furthermore, the pitch p of the overlapping portions 30 is preferably 10% to 18% of the total length when the paper thickness of the exterior sheet 22 is 0.2 mm, for example. By setting the pitch p within this range, it is possible to improve the strength of even a relatively thin exterior sheet 22. Furthermore, for example, when the paper thickness of the exterior sheet 22 is 0.5 mm, it is preferably 18% to 50% of the total length. By setting the pitch p within this range, it is possible to improve the strength of the cartridge 1 without making the entire cartridge 1 too thick.

[0034] In one embodiment of the present invention, a cylindrical cartridge 1 for a smoking article includes a filter member 13, a substrate 10 containing a filler 21, a transfer section 11 provided between the filter member 13 and the substrate 10, a support 12 supporting the filler 21, and an exterior sheet 22 wound around the substrate 10, the transfer section 11, the support 12, and the filter member 13 so as to be adjacent to each other in the longitudinal direction of the cartridge 1, and as shown in Figure 9, the exterior sheet 22 has a first region 40 along the longitudinal direction and a second region 43 that is closer to the filter member 13 than the first region 40 in the longitudinal direction, and the exterior sheet 22 in the first region 40 is wound spirally in a direction inclined to the longitudinal direction, and the exterior sheet 22 in the second region 43 is wound spirally in a direction intersecting the longitudinal direction. This configuration allows each component and base material 10 to be fastened in a manner suited to their respective characteristics, allowing for the use of wider components and base material 10, and also allows for the thickness and strength of the exterior to be tailored to suit the side that comes into contact with the device and the side that the user holds the cigarette when the cigarette is placed in the tobacco heating device.

[0035] The exterior sheets 22 may have a first overlapping portion 41 between the exterior sheets 22 and a first non-overlapping portion 42 in the first region 40, and may have a second overlapping portion 44 between the exterior sheets 22 and a second non-overlapping portion 45 in the second region 43. By having the first overlapping portion 41 and the second overlapping portion 44, it is possible to further improve the strength when fastening each member and the base material 10 in a manner suited to the respective characteristics of the members and the base material 10.

[0036] Moreover, it is preferable that the second range 43 includes the range of the end on the side where the filter member 13 is arranged. By adopting such a configuration, it is possible to partially provide strength suitable for when the user holds the cigarette or when the cigarette is placed in the mouth.

[0037] In the first region 40, the area of ​​the first overlapping portion 41 is preferably smaller than the area of ​​the first non-overlapping portion 42. By making the area of ​​the first overlapping portion 41 smaller than the area of ​​the first non-overlapping portion 42, the amount of exterior sheet 22 used can be minimized. Furthermore, the ratio of the area of ​​the first overlapping portion 41 to the area of ​​the first non-overlapping portion 42 is preferably 2% or more and less than 40%, more preferably 4% or more and less than 30%, and even more preferably 5% or more and less than 25%. The ratio of the area of ​​the first overlapping portion 41 may be uniform or may be non-uniform among the overlapping portions. When the first overlapping portion 41 and the non-overlapping portion are the same or when the non-overlapping portion is larger than the first overlapping portion 41, the strength is improved due to the increased overlapping portion.

[0038] In the second region 43, the range of the second overlapping portion 44 is preferably smaller than the range of the second non-overlapping portion 45. Furthermore, the ratio of the range of the second overlapping portion 45 to the range of the second non-overlapping portion 44 is preferably 2% or more and less than 40%, more preferably 4% or more and less than 30%, and even more preferably 5% or more and less than 25%. The ratio of the range of the second overlapping portion 44 may be uniform or may be non-uniform among the overlapping portions. When the second overlapping portion 44 and the non-overlapping portion are identical or the non-overlapping portion is larger than the second overlapping portion 44, the strength is improved due to the increased overlapping portion.

[0039] Furthermore, the ratio of the range of the second non-overlapping portion 45 to the range of the first overlapping portion 41 is preferably 80% or more and less than 120%, more preferably 90% or more and less than 110%, and even more preferably 95% or more and less than 100%.

[0040] The first overlap portion 41 preferably has a pitch p of 5% to 97% of the entire length in the longitudinal direction, and more preferably 7% to 55%.

[0041] Furthermore, the pitch p of the first overlap portion 41 is preferably 10% to 18% of the total length when the paper thickness of the exterior sheet 22 is 0.2 mm, for example. By setting the pitch p within this range, it is possible to improve the strength of even a relatively thin exterior sheet 22. Furthermore, for example, when the paper thickness of the exterior sheet 22 is 0.5 mm, it is preferably 18% to 50% of the total length. By setting the pitch p within this range, it is possible to improve the strength of the cartridge 1 without making the entire cartridge 1 too thick.

[0042] The second overlap portion 44 preferably has a pitch p of 5% to 97% of the entire length in the longitudinal direction, and more preferably 7% to 50%.

[0043] The ratio of the pitch of the second non-overlapping portion 45 to the pitch of the first overlapping portion 41 is preferably 80% or more and less than 120%, more preferably 90% or more and less than 110%, and even more preferably 95% or more and less than 100%. By adopting such a configuration, when a tobacco is placed in a tobacco heating device, the thickness and strength of the exterior can be set within more appropriate ranges on the side that comes into contact with the device and the side that the user holds the tobacco.

[0044] The exterior sheet 22 may be made of a single sheet or multiple sheets at least partially overlapped to form the overlapping portion 30 and the non-overlapping portion 31, or the first overlapping portion 41, the first non-overlapping portion 43, the second overlapping portion 44, and the second non-overlapping portion 45. When multiple sheets are at least partially overlapped, the overlapping portion 30 and the non-overlapping portion 31, or the first non-overlapping portion 43, the second overlapping portion 44, and the second non-overlapping portion 45 may be present in at least a portion of the exterior sheet 22.

[0045] Furthermore, it is preferable that the outer sheet 22 includes a covering portion (not shown) that covers the outer periphery of the outer sheet 22. By including the covering portion, it is possible to improve the design and strength. The covering portion can be made of the same material as the outer sheet 22.

[0046] Filler 21 may be in the form of strips parallel to the longitudinal direction of cartridge 1 (FIG. 4), or may be in the form of a sheet (FIG. 5), chips, a paste, sawdust, or powder (not shown). Here, powder includes powder, fine particles, fine grains, and granules. Since overlapping portion 30 extends in a direction inclined relative to the longitudinal direction of cartridge 1, it becomes easy to form a tube for exterior part 20 with improved strength in the longitudinal and lateral directions, and various forms of filler 21 can be used.

[0047] When the filler 21 is in the form of a strip or a sheet, the length of the filler 21 is preferably approximately equal to the height of the exterior part 20. That is, it is preferably 10.0 mm to 15.0 mm, and more preferably 11.0 mm to 13.0 mm. When the filler 21 is in the form of a strip, the width is preferably 0.1 mm to 1.0 mm, and more preferably 0.2 mm to 0.8 mm. When the filler 21 is in the form of a sheet, the thickness is preferably 0.1 mm to 1.0 mm, and more preferably 0.1 mm to 0.5 mm. When the filler 21 is in the form of granules, the average diameter is preferably 0.1 mm to 3.0 mm, and more preferably 0.4 mm to 0.8 mm.

[0048] Filler 21 can be prepared, for example, by mixing tobacco and / or non-tobacco material with an aerosol former that generates an aerosol, microcrystalline cellulose, additives that add flavor, preservatives, adhesives, thickeners, etc., and then passing the mixture through an orifice under pressure to form it into a rod; by forming the composition for filler 21 into a thin sheet and then cutting it into a different shape; or by drying the composition for filler 21 and grinding it into granules, etc.

[0049] Non-tobacco materials (aromatic components that produce aroma when heated) that form the filler 21 include, but are not limited to, the following:

[0050] The non-tobacco material that can be used in this embodiment is not particularly limited as long as it is from a plant other than tobacco. Various plant parts can be used, for example, roots (including bulbs, tuberous roots (tubers), bulbs, etc.), stems (corms, rhizomes, Jerusalem artichoke rhizophores), tubers, bark (including stem bark, bark, etc.), leaves, flowers (including petals, pistils, stamens, etc.), tree trunks and branches, etc.

[0051] Bulbs include onions, red spider lilies, tulips, hyacinths, garlic, radishes, and lilies; corms include crocuses, gladioli, freesias, irises, taro, and konjac; tubers include konjac, cyclamen, anemones, begonias, Chinese artichokes, potatoes, and apios; rhizomes include cannas, lotus roots, and ginger; tuberous roots include dahlias, sweet potatoes, cassava, and Jerusalem artichokes; rhizobis include the Dioscorea genus (yams such as Japanese yam, wild yam, and Chinese yam); and others include turnips, burdock, carrots, radishes, and kudzu. Stems include asparagus, bamboo shoots, burdock, radishes, and yacon.

[0052] The above-mentioned potatoes and the plants listed below contain carbohydrates and are preferably used as at least a portion of the material for the filling 21. For example, starch includes corn starch, potato starch, sweet potato starch, tapioca starch, etc., and is used as a thickener, stabilizer, etc. These starches can be crosslinked to improve acid resistance, heat resistance, shear resistance, etc., esterified or etherified to improve storage stability and promote gelatinization, etc., and oxidized to improve transparency, film properties, storage stability, etc.

[0066] Furthermore, extracts of the above-mentioned non-tobacco plants, so-called extracts, can also be used. The extracts may be in the form of liquid, starch syrup, powder, granules, solution, etc.

[0067] The support 12 is formed to support the filler 21 and is arranged between the transfer part 11 and the filter member 13. The presence of the support 12 allows the cartridge 1 to be inserted more smoothly into the electronic cigarette body, prevents bending of the cartridge 1, and improves operability. The length of the support 12 is preferably 10% to 40% of the total length of the cartridge 1, and more preferably 15% to 30%.

[0068] The filter member 13 is not particularly limited as long as it is made of a material that prevents the heated filler 21 from falling off or scattering dust, and can be made using, for example, a cellulose acetate filter. The filter member 13 absorbs the smoke and aromatic components of the aerosol, allowing the user to enjoy a more comfortable smoking experience. The length of the filter member 13 is preferably 12% to 60% of the total length of the cartridge 1, and more preferably 15% to 45%.

[0069] The filter member 13 may have a plurality of holes (not shown) formed at equal intervals along the circumferential direction to make it easier for the user to inhale the aerosol. The aerosol is cooled together with the outside air that flows in through the holes formed in the filter member 13, resulting in finer aerosol being dispersed well in the user's inhaled air, allowing the user to enjoy the aromatic components even more.

[0070] A lid member 14 may be formed on the end surface on the substrate 10 side to prevent spillage of the contents 21 (see FIG. 1). Because the exterior sheet 22 is spirally wound, the thickness of the outer shell of the cartridge 1 is also increased, allowing the lid member 14 to be attached to the end surface of the cartridge 1. The lid member 14 is not particularly limited as long as it is made of a material that prevents spillage of the contents 21. For example, it may be formed using the same material as the exterior sheet 22. Among these, paper substrates such as thick paper, plug wrap, cigarette paper, and tobacco paper are preferred because of their good breathability. The lid member 14 may also contain a liquid or fine powder. Examples of liquid or fine powder include burn regulators, fragrances, colorants, binders, protective materials, oily components, extracts, and antioxidants.

[0071] (Manufacturing method) Next, a method for manufacturing the cartridge 1 will be described.

[0072] In one embodiment of the present invention, a cylindrical cartridge 1 for a smoking article comprises: The cartridge 1 is manufactured by a method including a filter member 13, a substrate 10 including a filler 21, a transfer section 11 provided between the filter member 13 and the substrate 10, and an exterior sheet 22, in which the material for the filler 21, the transfer section 11, and the filter member 13 are arranged in this order on the flat exterior sheet 22, and the material for the filler 21, the transfer section 11, and the filter member 13 are wrapped in the exterior sheet 22, the exterior sheet 22 having overlapping portions 30 between the exterior sheets 22 and non-overlapping portions 31, and the overlapping portions 31 extending in a direction inclined with respect to the longitudinal direction of the cartridge 1.

[0073] Since each component is wrapped and tightened by the exterior sheet 22, misalignment due to differences in attributes is reduced, and it is possible to reduce the number of processes while maintaining quality.

[0074] First, we will explain the material of the filler 21. The production of the material of the filler 21 includes a drying and grinding process in which the tobacco material and / or non-tobacco material, which are the main raw materials, are dried and ground and weighed, etc., a preparation process in which other raw materials are pretreated and weighed, etc., a mixing process in which the raw materials are mixed to form a composition for the filler 21, and a filler 21 molding process in which the composition for the filler 21 is molded.

[0075] In the drying and grinding process, the tobacco and / or non-tobacco material used as the main raw material (e.g., leaves, seeds, dried fruit, stems, bark, roots, etc.) is processed into a predetermined ground material to form a composition. In this process, it is preferable to adjust the moisture content to a level suitable for absorbing or supporting the aerosol former, water, and other ingredients that will be added later. The drying temperature is preferably between 60°C and 80°C. By keeping the temperature in this range, it is easy to reach the desired moisture content while avoiding the loss of the required aromatic components. Note that if the temperature is 65°C or higher, it is even easier to reach the desired moisture content, and if it is 75°C or lower, the loss of the required aromatic components is even more prevented. It is possible.

[0076] The moisture content after drying and pulverization is preferably 5% by mass or less. This makes it easier to turn the material into a slurry in the subsequent process. A moisture content of 3% by mass or less is even more preferable. Furthermore, a moisture content of 0.1% by mass or more allows the material to maintain good compatibility with water, etc. Furthermore, the drying and pulverization process can also include a sieving process to sieve the pulverized material, allowing it to be adjusted to the desired particle size before being introduced into the mixing process.

[0077] In the preparation step, the raw materials required to produce the filler 21 can be prepared.

[0078] In the mixing step, a conventional mixer can be used. For example, a preferred mode is to mix the raw materials in a mixing vessel while applying shear force with a stirring blade.

[0079] In the filler forming process, the composition for filler 21, in which various raw materials are mixed, is formed into a thin sheet, which is then cut into strips, sheets, granules, or the like to form filler 21. In this embodiment, a roll mill is used to form the thin sheet. Using a roll mill is preferable because it allows for compression by being forced between narrow rolls and shearing due to the difference in roll speeds, while kneading and dispersing, etc., and then forming a sheet of the desired thickness using a doctor blade. Alternatively, a press roller or a press machine can be used to form the filler.

[0080] The filling forming step may also use other means, such as forcing the composition for filling 21 through an orifice under pressure to form it. Furthermore, in the filling forming step, non-tobacco plants, aerosol formers, binders or thickeners, flavor additives, preservatives, or water may also be added as needed.

[0081] In this embodiment, it is preferable to use water that has been sterilized or from which microorganisms have been removed, and it is preferable to use pure water obtained by reverse osmosis membrane or ion exchange.

[0082] The sheet obtained in the filling molding step is cut into a predetermined shape using a cutter, a rotary cutter using a rotary blade, or the like, to become the material for filling 21. The shape of filling 21 is preferably in the form of strips, sheets, chips, paste, sawdust, or powder. Here, powder includes powder, fine particles, fine grains, and granules.

[0083] The filler 21 material, the transfer section 11, (support 12), and the filter member 13 thus formed are arranged in this order and set on a flat exterior sheet 22. If the filler 21 material is strip-shaped, it is arranged parallel to the longitudinal direction. The flat exterior sheet 22 has a length corresponding to multiple cartridges 1. Each component is spirally wrapped in the exterior sheet 22 in a direction oblique to the longitudinal direction of the cartridge 1 to form the cartridge 1. At this time, by wrapping the exterior sheet 22 while winding it obliquely, an overlapping portion 30 and a non-overlapping portion 31 are formed, and the overlapping portion 30 may extend in a direction oblique to the longitudinal direction of the cartridge 1. In this case, glue is applied in advance to the area that will become the overlapping portion 30. The overlapping portion 30 becomes a glued portion extending circumferentially, which facilitates the formation of a tube of the exterior sheet 22 with improved strength in the longitudinal and lateral directions, thereby improving the strength of the entire cartridge 1. When the material of the filler 21 is in the form of strips, in order to form an efficient airflow, it is preferable that a plurality of materials of the filler 21 are arranged along the longitudinal direction of the cartridge 1. Examples of ways of wrapping the exterior sheet 22 include, but are not limited to, a method in which each component is fixed and the exterior sheet 22 rotates around them, or a method in which the feed of the exterior sheet 22 is fixed and each component rotates.

[0084] The manufacture of the cartridge 1 is completed through the process of forming a wound rod with the exterior sheet 22 and the cutting process. As an example, the cartridge 1 has an outer diameter of approximately 7.0 mm and a length of approximately 45.0 mm. At this time, a small amount of adhesive may be applied to the substrate 10 to fix it to the exterior sheet 22. Furthermore, to enhance the design and improve strength, a covering portion (not shown) may be formed around the outer periphery of the exterior sheet 22, wrapped in another sheet.

[0085] Next, a description will be given of a manufacturing method of the cartridge 1 in which the material of the filler 21 is wrapped in another exterior sheet 22. The manufacturing method in which the material of the filler 21 is wrapped in another exterior sheet 22 to form the exterior body 20 improves the ability of the base material 10 to hold various types of filler 21.

[0086] First, the material for the filler 21 formed as described above is set on a planar exterior sheet 22. The planar exterior sheet 22 has a length corresponding to a plurality of exterior portions 20.

[0087] Next, the filler 21 material is spirally wrapped in the exterior sheet 22 in a direction inclined relative to the longitudinal direction of the cartridge 1, forming a cylindrical exterior portion 20 filled with the filler 21. Furthermore, by wrapping the exterior sheet 22 while winding it at an angle, overlapping portions 30 and non-overlapping portions 31 are formed, and the overlapping portions 30 may extend in a direction inclined relative to the longitudinal direction of the cartridge 1. In this case, glue is applied in advance to the area that will become the overlapping portions 30. The overlapping portions 30 become glued portions extending circumferentially, which facilitates the formation of a cylindrical exterior portion 20 with improved strength in the longitudinal and lateral directions, thereby improving the strength of the entire cartridge. When the filler 21 material is in the form of strips, it is preferable that multiple pieces of filler 21 material be arranged along the longitudinal direction of the cartridge 1 to create an efficient airflow.

[0088] Methods of wrapping the outer sheet 22 include, for example, a method in which the filler 21 is fixed and the outer sheet 22 rotates around it, or a method in which the feed of the outer sheet 22 is fixed and the filler 21 side rotates, but are not limited to these.

[0089] The outer sheet 22 wraps around the filler 21 material, and the glued columnar shape (roll) is cut to a predetermined length to produce a cylindrical outer part 20, for example, with an outer diameter of approximately 6.9 mm and a length of approximately 12.0 mm.

[0090] Once the formation of the cylindrical exterior part 20 is complete, the base material 10 having the exterior part 20, the transport part 11, (support 12), and the filter member 13 are arranged adjacent to each other in this order, and then a process of forming a wound rod with another exterior sheet 22 is carried out, followed by a cutting process, to complete the manufacture of the cartridge 1. At this time, the base material 10 may be fixed to the other exterior sheet 22 by applying a small amount of adhesive. Also, to enhance the design or increase the strength, a covering part (not shown) may be formed on the outer periphery of the other exterior sheet 22.

[0091] 8, overlapping portions 30 and non-overlapping portions 31 can be formed by flat rolling. There are no particular limitations on how the exterior sheet 22 is wrapped flat, and it may be a single-layer type wrapped only once, or a multi-layer type wrapped multiple times until it reaches a predetermined thickness.

[0092] The outer sheet 22 wraps around the filler 21 material, and the glued columnar shape (roll) is cut to a predetermined length to produce a cylindrical outer part 20, for example, with an outer diameter of approximately 6.9 mm and a length of approximately 12.0 mm.

[0093] Once the formation of the cylindrical exterior part 20 is complete, the base material 10 having the exterior part 20, the transfer part 11, (support 12), and the filter member 13 are arranged adjacent to each other in this order, and a process of forming a wound rod with another exterior sheet 22 is carried out, completing the manufacture of the cartridge 1. As an example, the cartridge 1 has an outer diameter of approximately 7.0 mm and a length of approximately 45.0 mm. At this time, the base material 10 may be fixed to the other exterior sheet 22 by applying a small amount of adhesive. Furthermore, to enhance the design or increase the strength, a covering part may be formed on the outer periphery of the other exterior sheet 22.

[0094] In one embodiment of the present invention, a cylindrical cartridge 1 for a smoking article includes a filter member 13, a substrate 10 containing a filler 21, a transfer section 11 provided between the filter member 13 and the substrate 10, a support 12, and an exterior sheet 22; the material for the filler 21, the transfer section 11, the support 12, and the filter member 13 are arranged in this order on the planar exterior sheet 22; the material for the filler 21, the transfer section 11, the support 12, and the filter member 13 are wrapped in the exterior sheet 22 having a first region 40 along the longitudinal direction and a second region 43 that is closer to the filter member 13 in the longitudinal direction than the first region 40; in the first region 40, the exterior sheet 22 wraps spirally in a direction oblique to the longitudinal direction; and in the second region 43, the exterior sheet 22 wraps spirally in a direction intersecting the longitudinal direction.

[0095] Furthermore, a cartridge 1 may be manufactured in which the material of the filler 21, the transfer section 11, the support 12, and the filter member 13 are arranged adjacent to each other in this order on a flat exterior sheet 22, and the exterior sheet 22 is then rolled up at an angle, so that the exterior sheet 22 envelops each of the members and forms a first overlapping portion 41 and a second overlapping portion 43, or a first non-overlapping portion 42 and a second non-overlapping portion 45, and the exterior sheet 22 has, in a first range 40 along the longitudinal direction of the cartridge 1, the first overlapping portion 41 and the first non-overlapping portion 42 between the exterior sheets 22, and in a second range 43 along the longitudinal direction, the second overlapping portion 44 and the second non-overlapping portion 45 between the exterior sheets 22, and the first overlapping portion 41 extends in a direction oblique to the longitudinal direction, and the second overlapping portion 43 extends in a direction intersecting the longitudinal direction. Since each component is wrapped and tightened by the exterior sheet 22, misalignment due to differences in attributes is reduced, and it is possible to reduce the number of processes while maintaining quality.

[0096] The first overlapping portion 41 in the first region 40 and the second overlapping portion 43 in the second region 43 may be formed separately by preparing respective exterior sheets 22, or may be formed by changing the wrapping direction of a single exterior sheet 22. Furthermore, when separate exterior sheets 22 are prepared, the wrapping directions for forming the first overlapping portion 41 in the first region 40 and the second overlapping portion 43 in the second region 43 may be the same as or different from each other, as shown in FIG.

[0097] A step of applying a small amount of adhesive to the cover member 14 and fixing it to the end portion on the substrate side may be added. This step may be performed before or after the cutting step described above.

[0098] Although the present invention has been described above using embodiments, it goes without saying that the technical scope of the present invention is not limited to the scope described in the above embodiments and examples. It will be apparent to those skilled in the art that various modifications and improvements can be made to the above embodiments. Furthermore, it is clear from the claims that such modifications and improvements can also be included within the technical scope of the present invention. [Explanation of symbols]
