Description

Technical Field

[0001] The present invention relates to a columnar cartridge for a smoking device and a method for manufacturing the columnar cartridge for a smoking device.

Background Art

[0002] In recent years, in order to conform to the trend of tobacco smoking bans, electronic cigarette products for enjoying tobacco have begun to spread by heating a columnar cartridge for a smoking device containing tobacco components without using a flame and sucking the vaporized tobacco components. As the structure of such a cartridge, for example, it includes a filter member, a base material provided with a filler containing tobacco components, a support member provided between the filter member and the base material for supporting the base material, and an outer packaging sheet that wraps each member in a flat spiral in a single columnar shape and adheres and fixes the end portion in the longitudinal direction with glue or the like (see Patent Document 1).

[0003] When the user uses the cartridge, the base material is inserted into the insertion portion of the electronic cigarette main body, and the base material is heated by a heating element at the center of the bottom in the insertion portion, so that an aerosol is generated from the filler. When the user sucks the aerosol from the filter member side, the tobacco components reach the user's mouth (see Patent Document 1, FIG. 4).

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, when a user inserts a cartridge into the e-cigarette device, bending and twisting forces are applied to the cartridge. In flat-wound cartridges where the overlapping adhesive portion is in a straight line along the length, the cartridge is weak against bending and can peel or tear.

[0006] Furthermore, when packaging the cartridges with an outer sheet, differences in attributes such as rigidity, hardness, and strength, as well as outer diameter, made it difficult to wrap them flat without gaps. This sometimes resulted in the components and base materials shifting in the longitudinal direction, creating gaps. These gaps not only degraded the quality of the cigarette itself but also affected productivity and strength, requiring multiple processes, such as wrapping each component and base material individually with the outer sheet.

[0007] This invention has been made in view of these circumstances, and its purpose is to provide a columnar cartridge for smoking devices and a method for manufacturing the same, which improves the overall strength of the cartridge, reduces misalignment of individual components during the manufacturing process, and reduces the number of manufacturing steps while maintaining the quality of the tobacco itself. [Means for solving the problem]

Embodiments for Carrying Out the Invention

[0012] Hereinafter, embodiments for carrying out the present invention (hereinafter, embodiments) will be described in detail with reference to the drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant descriptions are omitted. Further, the dimensional ratios in the drawings are merely examples and are not limited thereto. Furthermore, for the sake of explanation, there may be cases where it is exaggerated partially.

[0013] In addition, in this specification, "smoking" generally often means inhaling smoke containing nicotine, tar, etc. generated by burning or heating tobacco leaves of the genus Nicotiana in the Solanaceae family or materials containing tobacco components. Here, however, it simply means "enjoying smoke", "tasting smoke", or "relishing smoke", and the aromatic components that form the smoke are not limited to tobacco materials and are also applicable to those using non-tobacco materials.

[0014] As shown in FIGS. 1 to 6, in one embodiment of the present invention, a columnar cartridge 1 for a smoking device includes a filter member 13, a base material 10 containing a filling 21, a transfer portion 11 provided between the base material 10, and the filter member 13 and an outer packaging sheet 22.

[0015] FIG. 1 is a cross-sectional view showing an example of the structure of a columnar cartridge 1 for a smoking device. The cartridge 1 shown in FIG. 1 includes a base material 10 containing a filling 21, a filter member 13, and a transfer portion 11 provided between the filter member 13 and the base material 10, and exhibits a columnar appearance. Further, a lid member 14 may be included at an end on the side of the base material 10 containing the filling 21. Here, one direction in which the three elements of the base material 10, the transfer portion 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 outer packaging sheet 22 is wound in a spiral shape in a direction inclined with respect to the longitudinal direction of the cartridge 1. By winding the outer packaging sheet 22 in a spiral shape, the strength of the cartridge 1 against bending is improved.

[0017] The transfer portion 11 is arranged adjacent to the base material 10. The transfer portion 11 is not particularly limited as long as it is a material having excellent heat resistance, and for example, it can be formed using silicone. The length of the transfer portion 11 is preferably 10% or more and 40% or less of the total length of the cartridge 1, and more preferably 15% or more and 30% or less.

[0018] Furthermore, the cartridge 1 shown in Figure 3 is a cross-sectional view illustrating another embodiment of the structure of a columnar cartridge for smoking devices. The cartridge 1 includes a base material 10 containing a filler 21, a support 12 supporting the filler 21, a filter member 13, a transfer section 11 provided between the support 12 and the base material 10, and an outer sheet 22, and has a columnar appearance.

[0019] The base material 10, support 12, transfer unit 11, and filter member 13 are packaged by an outer sheet 22. The longitudinal direction of the cartridge 1 and the longitudinal direction of the base material 10 are, for example, parallel. Furthermore, the configuration with the support 12 stabilizes the aerosol airflow, making it easier for the user to inhale the fragrance components.

[0020] The transfer section 11 may form a support member 15 that supports the base material 10 containing the filler 21, as is commonly used. Furthermore, since the cartridge 1 has improved strength against bending, the transfer section 11 may be formed from a sponge, foam, fiber aggregate, porous material, or a rod-shaped object that does not come into contact with the inner surface of the outer casing of the cartridge 1 (see Figure 1).

[0021] Furthermore, the transfer section 11 may be provided with an airflow passage hole in its center. The presence of this passage hole allows the aerosol generated on the substrate 10 to pass through the airflow passage hole and flow efficiently towards the filter member 13. It is also possible to provide the transfer section 11 with airflow passage holes or notches on its sides.

[0022] The outer sheet 22 has overlapping portions 30 and non-overlapping portions 31, and the overlapping portions 30 may extend in a direction inclined with respect to the longitudinal direction of the cartridge 1.

[0023] Figures 4 and 5 show an example of the filler 21 (filled state) of the base material 10. The base material 10 includes the filler 21 filled inside the outer sheet 22. The outer sheet 22 has overlapping portions 30 and non-overlapping portions 31, and the overlapping portions 30 extend in a direction inclined with respect to the longitudinal direction of the cartridge 1. The outer sheet 22 covering the filler 21 covers the base material 10, support 12, transfer section 11 and filter member 13, but the filler 21 may be covered with an outer sheet 22 separate from the outer sheet 22, and the base material 10 may be configured to include a cylindrical outer section 20 (see Figure 6) and the filler 21. This configuration improves the ability of the cartridge 1 to hold the filler 21.

[0024] In the outer sheet 22, the overlap portion 30 extending in a direction inclined with respect to the longitudinal direction can be formed, for example, by preparing a parallelogram-shaped outer sheet 22, rolling it into a columnar shape, and gluing both ends together to form a loop, thereby configuring the glued portion as the overlap portion 30. The outer sheet 22 has overlap portions 30 and non-overlapping portions 31, and the overlap portion 30 extends in a direction inclined with respect to the longitudinal direction of the cartridge 1, making it possible to provide a glued portion extending in the circumferential direction on the outer sheet 22 of the cartridge 1. This distributes the twisting or bending force applied by the user to the cartridge 1, thereby improving the overall strength of the cartridge 1.

[0025] Furthermore, as shown in Figure 6, the overlap portion 30 may be constructed by preparing a tape-shaped outer sheet 22 and winding it spirally to overlap it and form a columnar object. By making the overlap portion 30 spiral, a spiral step can be created on the inner surface of the outer sheet 22. This step creates a smooth airflow of aerosol, which can improve the taste and aroma and enhance the efficiency of exhalation.

[0026] Furthermore, as shown in Figure 7, multiple parallelogram-shaped sheets may be bonded together with only the edges overlapping to form the outer sheet 22, and then, as shown in Figure 7, the outer sheet 22 may be wound in a flat winding manner. This configuration makes it possible to improve the strength of the outer casing of the cartridge 1 without changing the flat winding 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 end of the outer sheet 22 constituting the non-overlapping portion 31 and the edge end of the outer sheet 22 constituting 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 with multiple overlapping portions 30, the range is the arithmetic mean of these overlapping portions. By making the range of the overlapping portion 30 smaller than the range of the non-overlapping portion 31, the amount of outer 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%. The overlap may be uniform or non-uniform. If the overlapping portion 30 and the non-overlapping portion are the same size, or if the non-overlapping portion is larger than the overlapping portion 30, the strength is improved because the overlapping portion increases.

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

[0029] The inner surface of the outer sheet 22 may be coated or impregnated with a fragrance. The fragrance is not particularly limited as long as it is one that is generally used in columnar cartridges 1 for smoking accessories, and examples include tobacco extract, vanillin, chocolate, cocoa, menthol, etc.

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

[0031] The average outer diameter d of the outer casing 20 (see Figure 6) or the average outer diameter d of the cartridge 1 in which the outer sheet 22 is wound spirally in a direction inclined with respect to the longitudinal direction is preferably 5.0 mm or more and 8.0 mm or less from the viewpoint of ease of handling by the user. In the case of cartridge 1, "outer diameter" means the diameter if the cross-section is circular, and the length of the major axis if it is elliptical. Furthermore, in this specification, even if the cross-section in the direction perpendicular to the longitudinal direction is polygonal, it is still considered cartridge 1, and the "outer diameter" is the diameter of the circumscribed circle having the largest diameter among one or more circles circumscribed around the polygon.

[0032] The overlap portion 30 preferably has 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 overlap portion 30 becomes narrower, reducing the bonding surface and decreasing productivity. Also, the outer surface of the cartridge 1 will have many inclined lines, resulting in many points where it bends. On the other hand, if it exceeds 55%, it becomes difficult to arrange the components and base material 10 that make up the cartridge 1 without gaps, and the extension of the overlap portion 30 will reduce the overall strength.

[0033] Furthermore, the pitch p of the overlap portion 30 is preferably such that, for example, when the paper thickness of the outer sheet 22 is 0.2 mm, the pitch p is between 10% and 18% of the total length. By setting it within this range, the strength can be improved even with a relatively thin outer sheet 22. Moreover, for example, when the paper thickness of the outer sheet 22 is 0.5 mm, the pitch p is preferably such that it is between 18% and 50% of the total length. By setting it within this range, the strength can be improved without making the entire cartridge 1 too thick.

[0034] Furthermore, in one embodiment of the present invention, a columnar cartridge 1 for a smoking device includes a filter member 13, a base material 10 containing a filler 21, a transfer section 11 provided between the filter member 13 and the base material 10, a support 12 for supporting the filler 21, and an outer sheet 22 that is wound around the base material 10, the transfer section 11, the support 12, and the filter member 13 so that they are arranged adjacent to each other in the longitudinal direction of the cartridge 1. The outer sheet 22 may be configured such that, as shown in Figure 9, it has a first range 40 along the longitudinal direction and a second range 43 closer to the filter member 13 than the first range 40 in the longitudinal direction, and the outer sheet 22 in the first range 40 is wound spirally in a direction inclined with respect to the longitudinal direction, and the outer sheet 22 in the second range 43 is wound spirally in a direction intersecting with respect to the longitudinal direction. By adopting this configuration, each component and the base material 10 can be fastened and secured in a manner suitable to their respective characteristics, allowing for the use of wider components and base material 10. Furthermore, when attaching a cigarette to a cigarette heating device, the thickness and strength of the outer casing can be adjusted to suit the side that contacts the device and the side that the user holds the cigarette.

[0035] The outer sheet 22 may have a configuration in which, within a first range 40, there is a first overlap portion 41 and a first non-overlapping portion 42 between the outer sheets 22, and within a second range 43, there is a second overlap portion 44 and a second non-overlapping portion 45 between the outer sheets 22. By having the first overlap portion 41 and the second overlap portion 44, the strength can be further improved in fastening and fixing that is suitable for the respective characteristics of each member and the base material 10.

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

[0037] In the first range 40, it is preferable that the range of the first overlap portion 41 is smaller than the range of the first non-overlapping portion 42. By making the range of the first overlap portion 41 smaller than the range of the first non-overlapping portion 42, the amount of outer sheet 22 used can be minimized. Furthermore, the ratio of the range of the first overlap portion 41 to the range 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%. Note that the ratio of the range of the first overlap portion 41 may be uniform or may be non-uniform in each overlap portion. If the first overlap portion 41 and the non-overlapping portion are the same size or the non-overlapping portion is larger than the first overlap portion 41, the strength is improved because the overlapping portion increases.

[0038] In the second range 43, it is preferable that the range of the second overlapping portion 44 is 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%. Note that the ratio of the range of the second overlapping portion 44 may be uniform or may be non-uniform in each overlapping portion. If the second overlapping portion 44 and the non-overlapping portion are the same size or the non-overlapping portion is larger than the second overlapping portion 44, the strength is improved because the overlapping portion increases.

[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 its total length in the longitudinal direction, and more preferably 7% to 55%.

[0041] Furthermore, the pitch p of the first overlap portion 41 is preferably such that, for example, when the paper thickness of the outer sheet 22 is 0.2 mm, the pitch p is between 10% and 18% of the total length. By setting it within this range, the strength can be improved even with a relatively thin outer sheet 22. Moreover, for example, when the paper thickness of the outer sheet 22 is 0.5 mm, the pitch p is preferably such that it is between 18% and 50% of the total length. By setting it within this range, the strength can be improved without making the entire cartridge 1 too thick.

[0042] Furthermore, the second overlap portion 44 preferably has a pitch p of 5% to 97% of the total 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%. With this configuration, when attaching a cigarette to a cigarette heating device, the thickness and strength of the outer casing can be provided within a more appropriate range for both the side that contacts the device and the side that the user holds the cigarette.

[0044] The exterior sheet 22 may consist of one or more sheets overlapping at least a portion of each other to form an overlapping portion 30 and a non-overlapping portion 31, or a first overlapping portion 41, a first non-overlapping portion 43, a second overlapping portion 44, and a second non-overlapping portion 45. When multiple sheets are overlapped at least a portion of each other, 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, only need to be present in at least a portion of the exterior sheet 22.

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

[0046] The filling material 21 may be in the form of strips parallel to the longitudinal direction of the cartridge 1 (Figure 4), or it may be in the form of a sheet (Figure 5), chips, paste, wood chips, or powder (not shown). Here, the powder form includes powder, fine particles, granules, and solid particles. As a result of the overlap portion 30 extending in a direction inclined with respect to the longitudinal direction of the cartridge 1, it becomes easier to form a cylindrical outer casing 20 with improved strength in both the longitudinal and transverse directions, and various forms of filling material 21 can be used.

[0047] When the filler 21 is in the form of strips or sheets, it is preferable that the length of the filler 21 is approximately equal to the height of the outer packaging 20. That is, it is preferably 10.0 mm or more and 15.0 mm or less, and more preferably 11.0 mm or more and 13.0 mm or less. Furthermore, when the filler 21 is in the form of strips, the width is preferably 0.1 mm or more and 1.0 mm or less, and more preferably 0.2 mm or more and 0.8 mm or less. Furthermore, when the filler 21 is in the form of sheets, the thickness is preferably 0.1 mm or more and 1.0 mm or less, and more preferably 0.1 mm or more and 0.5 mm or less. In addition, when the filler 21 is in the form of granules, the average diameter is preferably 0.1 mm or more and 3.0 mm or less, and more preferably 0.4 mm or more and 0.8 mm or less.

[0048] Examples of methods for preparing the filling material 21 include mixing tobacco material and / or non-tobacco material with an aerosol former that generates an aerosol, microcrystalline cellulose, flavor enhancers, preservatives, adhesives, thickeners, etc., and then passing the mixture through an orifice under pressure to form a rod shape; forming the composition for the filling material 21 into a thin sheet and then cutting it; or drying and crushing the composition for the filling material 21 to form granules.

[0049] The following are examples of non-tobacco materials (aromatic components that produce fragrance when heated) that form the filling material 21, but are not limited to these.

[0050] In this embodiment, any non-tobacco material other than tobacco can be used without any particular restrictions. Various parts of the plant can be used, such as roots (including bulbs, tubers, tubers, etc.), stems (corms, rhizomes, Jerusalem artichoke rhizomes), tubers, bark (including stem bark, tree bark, etc.), leaves, flowers (including petals, pistils, stamens, etc.), tree trunks and branches, etc.

[0051] Examples of bulbs include onions, spider lilies, tulips, hyacinths, garlic, shallots, and lilies; examples of corms include crocuses, gladiolus, freesias, irises, taro, and konjac; examples of tubers include konjac, cyclamen, anemones, begonias, Chinese artichokes, potatoes, and apios; examples of rhizomes include cannas, lotus (lotus root), and ginger; examples of tubers include dahlias, sweet potatoes, cassava, and Jerusalem artichokes; examples of rhizomes include the genus Dioscorea (Japanese yam, wild yam, Chinese yam, and other yam species); and others include turnips, burdock, carrots, radishes, and kudzu. Examples of stems include asparagus, bamboo shoots, Japanese angelica tree, radishes, and yacon.

[0052] The above-mentioned tubers or the plants listed below contain carbohydrates and are preferably used as at least a part of the filling material 21. For example, starches include corn starch (corn), potato starch (potato), sweet potato starch (sweet potato), tapioca starch (tapioca), etc., and have been used as thickeners, stabilizers, etc. These starches can be improved by crosslinking to enhance acid resistance, heat resistance, and shear resistance, etc., by esterification and etherification to improve storage stability and accelerate gelatinization, etc., and by oxidation to improve transparency, film properties, and storage stability, etc.

[0053] From plant seeds, tamarind seed gum, guar gum, and locust bean gum can be obtained; from tree sap, gum arabic and karaya gum; from fruits, pectin; and from other plants, konjac mannan (mainly composed of cellulose and agarose) and soybean polysaccharides can be obtained. Furthermore, these can be modified and used, such as cationized guar gum.

[0066] Furthermore, extracts of non-tobacco plants, as exemplified above, can also be used. These extracts may take the form of liquid, syrup, powder, granules, or solution.

[0067] The support 12 is formed to support the filling 21 and is arranged between the transport section 11 and the filter member 13. The presence of the support 12 makes it easier to insert the cartridge 1 into the e-cigarette body, prevents the cartridge 1 from bending, 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 filling material 21 from falling off or dust from scattering. For example, it can be formed using a cellulose acetate filter. The filter member 13 draws in aerosol smoke and aromatic components, 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 multiple holes (not shown) formed at equal intervals along its circumference to make it easier for the user to inhale aerosols. As a result of the aerosols being cooled together with the outside air flowing in through the holes formed in the filter member 13, finer aerosols are better dispersed in the user's inhaled air, allowing for a greater enjoyment of aromatic components.

[0070] A lid member 14 may be formed on the end face of the base material 10 to prevent the filling 21 from spilling (see Figure 1). Since the outer sheet 22 is wound in a spiral shape, the thickness of the outer casing of the cartridge 1 is also increased, allowing the lid member 14 to be attached to the end face of the cartridge 1. The lid member 14 is not particularly limited as long as it is made of a material that prevents the filling 21 from spilling, and can be formed using, for example, the same material as the outer sheet 22. Among these, paper base materials such as thick paper, plug wrap, cigarette paper, and tobacco paper are preferred due to their good breathability. The lid member 14 may also contain liquid or fine powder. Examples of liquid or fine powder include combustion regulators, fragrances, dyes, binders, protective materials, oily components, extracts, and antioxidants.

[0071] (Manufacturing method) Next, we will explain the manufacturing method of cartridge 1.

[0072] In one embodiment of the present invention, a columnar cartridge 1 for a smoking device is The cartridge 1 is manufactured by a method that includes a filter member 13, a base material 10 containing a filling material 21, a transfer unit 11 provided between the filter member 13 and the base material 10, and an outer sheet 22, wherein the filling material 21, the transfer unit 11, and the filter member 13 are arranged in this order on the flat outer sheet 22, and the filling material 21, the transfer unit 11, and the filter member 13 are wrapped by the outer sheet 22, and the outer sheet 22 has overlapping portions 30 and non-overlapping portions 31, with 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 compressed by the outer sheet 22, deviations due to differences in attributes are reduced, making it possible to reduce the number of processes while maintaining quality.

[0074] First, let's explain the materials for the filler 21. The manufacturing of the materials for the filler 21 includes a drying and grinding step in which the main raw materials, tobacco and / or non-tobacco materials, are dried, ground, and weighed; a preparation step in which other raw materials are pre-treated and weighed; a mixing step in which the raw materials are mixed to form the composition for the filler 21; and a filler 21 molding step in which the composition for the filler 21 is molded.

[0075] In the drying and grinding process, the tobacco and / or non-tobacco materials used as the main raw materials (e.g., leaves, seeds, dried fruits, stems, bark, roots, etc.) are processed into a predetermined pulverized material to form the composition. At this time, it is preferable to adjust the moisture content to a level suitable for absorbing or supporting the aerosol former, water, and other components to be added later. During drying, a temperature of 60°C to 80°C is preferred. This range makes it easier to reach the desired moisture content while avoiding the dissipation of necessary aromatic components. A temperature of 65°C or higher makes it even easier to reach the desired moisture content, while a temperature of 75°C or lower further prevents the dissipation of necessary aromatic components. It is possible.

[0076] The moisture content after drying and grinding should preferably be 5% by mass or less. This facilitates slurry formation in subsequent processes. 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 and other liquids. In addition, a sieving step can be included in the drying and grinding process to separate the ground material, allowing it to be adjusted to the desired particle size before being added to the mixing process.

[0077] In the preparation process, the raw materials necessary for creating the filling 21 can be prepared.

[0078] In the mixing process, a conventional mixer can be used. For example, a configuration in which the raw materials in the mixing tank are mixed while applying shear force with stirring blades is preferably used.

[0079] In the filler molding process, the filler 21 is formed by first molding the filler composition 21, which is a mixture of various raw materials, into a thin sheet, and then cutting it into strips, sheets, granules, etc. In this embodiment, a roll mill is used to make a thin sheet. Using a roll mill is preferable because it is possible to knead and disperse the material through compression by pressing it between narrow rolls and shearing due to the difference in roll speeds, while simultaneously forming a sheet of the desired thickness with a doctor blade. Alternatively, it can also be produced using a press roller or a press machine.

[0080] In the filling molding process, other means may be used, such as molding the filling composition 21 by passing it through an orifice under pressure. In addition, in the filling molding process, non-tobacco plants, aerosol formers, binders or thickeners, flavor additives, preservatives, etc. may be added as needed, or water may be added.

[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 or ion exchange.

[0082] The sheet obtained in the filler molding process is cut into a predetermined shape using a cutter, a rotary cutter with a rotating blade, etc., to become the material for the filler 21. The filler 21 can take the form of strips, sheets, chips, paste, wood chips, or powder. Here, the powder form includes powder, fine particles, granules, and solid particles.

[0083] The packing material 21, the transfer section 11, the support 12, and the filter member 13 formed in this manner are arranged in this order and set on the flat outer sheet 22. If the packing material 21 is in the shape of strips, they are arranged parallel to the longitudinal direction. The flat outer sheet 22 has a length equal to that of multiple cartridges 1. Each member is wrapped spirally by the outer sheet 22 in a direction inclined with respect to the longitudinal direction of the cartridge 1 to form the cartridge 1. At this time, by wrapping the outer sheet 22 while winding it at an angle, an overlap portion 30 and a non-overlapping portion 31 are formed, and the overlap portion 30 may extend in a direction inclined with respect to the longitudinal direction of the cartridge 1. In this case, adhesive is applied in advance to the area that will become the overlap portion 30. The overlap portion 30 becomes an adhesive portion that extends in the circumferential direction, making it easier to form a cylinder of the outer sheet 22 with improved strength in the longitudinal and transverse directions, and improving the overall strength of the cartridge 1. When the material of the packing 21 is in the shape of strips, it is preferable that multiple pieces of the packing 21 material be arranged along the longitudinal direction of the cartridge 1 in order to form an efficient airflow. Examples of how the outer sheet 22 is wrapped include, but are not limited to, a method in which each component 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 each component rotates.

[0084] After the process of forming a winding rod with the outer sheet 22 described above, and the cutting process, the manufacturing of the cartridge 1 is completed. As an example, the cartridge 1 will have an outer diameter of approximately 7.0 mm and a length of approximately 45.0 mm. At this time, it is also possible to fix the base material 10 to the outer sheet 22 by applying a small amount of adhesive. Furthermore, in order to enhance the design or improve strength, a covering portion (not shown) wrapped with another sheet may be formed around the outer circumference of the outer sheet 22.

[0085] Next, a method for manufacturing the cartridge 1, in which the material of the filler 21 is wrapped with another outer sheet 22, will be described. By manufacturing the cartridge 1 in which the material of the filler 21 is wrapped with another outer sheet 22 to form the outer body 20, an improvement in the ability of the base material 10 to hold various types of filler 21 can be obtained.

[0086] First, the material for the filler 21 formed as described above is set on a flat outer sheet 22. The flat outer sheet 22 has a length of multiple outer sections 20.

[0087] Next, the material of the filler 21 is spirally wrapped with the outer sheet 22 in a direction inclined with respect to the longitudinal direction of the cartridge 1, forming a cylindrical outer part 20 filled with the filler 21. At this time, by wrapping the outer sheet 22 while winding it at an angle, an overlap portion 30 and a non-overlap portion 31 are formed, and the overlap portion 30 may extend in a direction inclined with respect to the longitudinal direction of the cartridge 1. In this case, adhesive is applied in advance to the area that will become the overlap portion 30. The overlap portion 30 becomes an adhesive portion that extends in the circumferential direction, making it easier to form a cylindrical outer part 20 with improved strength in the longitudinal and transverse directions, thereby improving the overall strength of the cartridge. When the material of the filler 21 is in the shape of strips, it is preferable that multiple pieces of the filler 21 material are arranged along the longitudinal direction of the cartridge 1 in order to form an efficient airflow.

[0088] Methods for enclosing the outer sheet 22 include, but are not limited to, a method in which the filling material 21 is fixed and the outer sheet 22 rotates around it, or a method in which the feeding of the outer sheet 22 is fixed and the filling material 21 rotates.

[0089] The outer sheet 22 encloses the material of the filling 21, and the glued columnar object (roll) is cut to a predetermined length, resulting in a cylindrical outer section 20 with an outer diameter of approximately 6.9 mm and a length of approximately 12.0 mm.

[0090] Once the cylindrical outer casing 20 is formed, the base material 10 having the outer casing 20, the transfer section 11, (support 12), and the filter member 13 are arranged adjacent to each other in that order. The process involves forming a winding rod with another outer sheet 22, followed by a cutting process, to complete the manufacturing of the cartridge 1. At this time, the base material 10 may be fixed to the other outer sheet 22 by applying a small amount of adhesive. In addition, a covering portion (not shown) may be formed on the outer circumference of the other outer sheet 22 to enhance the design or improve strength.

[0091] Furthermore, in the case of the outer sheet 22 shape shown in Figure 8, an overlapping portion 30 and a non-overlapping portion 31 can be formed by flat winding. The wrapping of the outer sheet 22 by flat winding is not particularly limited to a single-layer type where it is wound only once, or a multi-layer type where it is wound multiple times until a predetermined thickness is reached.

[0092] The outer sheet 22 encloses the material of the filling 21, and the glued columnar object (roll) is cut to a predetermined length, resulting in a cylindrical outer section 20 with an outer diameter of approximately 6.9 mm and a length of approximately 12.0 mm.

[0093] Once the cylindrical outer casing 20 is formed, the base material 10 having the outer casing 20, the transfer section 11, (support 12), and the filter member 13 are arranged adjacent to each other in that order, and the manufacturing of the cartridge 1 is completed by forming a winding rod with another outer sheet 22. As an example, the cartridge 1 will have 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 outer sheet 22 by applying a small amount of adhesive. In addition, a covering portion may be formed on the outer circumference of the other outer sheet 22 to enhance the design or improve strength.

[0094] Furthermore, in one embodiment of the present invention, a columnar cartridge 1 for a smoking device includes a filter member 13, a base material 10 containing a filler 21, a transfer unit 11 provided between the filter member 13 and the base material 10, a support 12, and an outer sheet 22. The material of the filler 21, the transfer unit 11, the support 12, and the filter member 13 are arranged in this order on a planar outer sheet 22. The material of the filler 21, the transfer unit 11, the support 12, and the filter member 13 are wrapped by the outer sheet 22 having a first range 40 along the longitudinal direction and a second range 43 closer to the filter member 13 than the first range 40 in the longitudinal direction. In the first range 40, the outer sheet 22 is spirally wrapped in a direction inclined with respect to the longitudinal direction, and in the second range 43, the outer sheet 22 is spirally wrapped in a direction intersecting with respect to the longitudinal direction.

[0095] Furthermore, a cartridge 1 may be manufactured in which the filling material 21, the transfer section 11, the support 12, and the filter member 13 are placed adjacent to each other in that order on a flat outer sheet 22, and the outer sheet 22 is wound at an angle so that the outer sheet 22 encloses each member, forming a first overlap portion 41 and a second overlap portion 43, or a first non-overlapping portion 42 and a second non-overlapping portion 45, and the outer sheet 22 has a first overlap portion 41 and a first non-overlapping portion 42 in a first range 40 along the longitudinal direction of the cartridge 1, and a second overlap portion 44 and a second non-overlapping portion 45 in a second range 43 along the longitudinal direction, the first overlap portion 41 extends in a direction inclined with respect to the longitudinal direction, and the second overlap portion 43 extends in a direction intersecting the longitudinal direction. Since each component is wrapped and compressed by the outer sheet 22, deviations due to differences in attributes are reduced, making it possible to reduce the number of processes while maintaining quality.

[0096] The first overlap portion 41 of the first range 40 and the second overlap portion 43 of the second range 43 may be formed separately by preparing separate outer sheets 22, or they may be formed by changing the direction in which they are wrapped with a single outer sheet 22. Furthermore, if they are prepared separately, the winding direction for forming the first overlap portion 41 of the first range 40 and the second overlap portion 43 of the second range 43 may be the same direction or different, as shown in Figure 9.

[0097] An additional step may be taken to apply a small amount of adhesive to the lid member 14 and fix it to the end on the base material side. This step can be performed either 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 obvious to those skilled in the art that various modifications or improvements can be made to the above embodiments. Furthermore, it is clear from the claims that such modified or improved forms may also be included in the technical scope of the present invention. [Explanation of symbols]
