Description

The present invention relates to a cylindrical cartridge for a smoking article and a method for manufacturing a cylindrical cartridge for a smoking article.

In recent years, in order to keep up with the trend towards smoking cessation, electronic cigarette products have become popular, which allow users to enjoy tobacco without using a flame by heating a cylindrical cartridge for smoking devices that contains tobacco components and inhaling the vaporized tobacco components. The structure of such a cartridge includes, for example, a filter member, a base material with a filler that contains tobacco components, a support member that is provided between the filter member and the base material and supports the base material, and an exterior sheet that wraps each member flat into a single cylindrical shape and adheres and fixes the longitudinal end portions with glue or the like (see Patent Document 1).

When a user uses the cartridge, the base material is inserted into the insertion section of the electronic cigarette body, and the base material is heated by a heating element located in the center of the bottom of the insertion section, generating an aerosol from the filling. When the user inhales the aerosol from the filter member side, the tobacco components reach the user's mouth (see Patent Document 1, Figure 4).

JP 2019-000094 A

However, when a user inserts a cartridge into the electronic cigarette body, the cartridge is subjected to bending and twisting forces, and flat-wound cartridges, in which the overlapping glued portions are in a straight line along the length, are vulnerable to bending and can peel off or tear.

In addition, when packaging the cartridges in an exterior sheet, it was difficult to roll the cartridges flat without gaps due to differences in the rigidity, hardness, strength, and other attributes of each component and base material, as well as differences in outer diameter, and each component and base material could shift longitudinally, resulting in gaps. Gaps not only reduce the quality of the cigarette body, but also affect productivity and strength, so multiple processes were required, such as wrapping the exterior sheet around each component and base material.

The present invention was made in light of these circumstances, and its purpose is to provide a cylindrical cartridge for smoking articles and a manufacturing method thereof that improves the strength of the entire cartridge, reduces misalignment of components during the manufacturing process, and reduces the number of manufacturing steps while maintaining the quality of the cigarette body.

The inventors of the present invention have conducted intensive research in light of the above problems. As a result, they have discovered that the above problems can be solved by the cartridge of the following aspect, and have completed the present invention. Specifically, the present invention provides the following:

Below, a mode for carrying out the present invention (hereinafter, "embodiment") will be described in detail with reference to the drawings. Note that in the description of the drawings, the same elements are given the same reference numerals, and duplicated description will be omitted. Also, the dimensional ratios in the drawings are merely examples, and are not intended to be limiting. Furthermore, some parts may be exaggerated for the sake of explanation.

In addition, in this specification, "smoking" generally means inhaling smoke containing nicotine, tar, etc., produced by burning or heating tobacco leaves of the Nicotiana genus in 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 are the source of smoke are not limited to tobacco materials, but also apply to those that use non-tobacco materials.

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 base material 10 containing a filler 21, a transfer section 11 provided between the base material 10, the filter member 13, and an exterior sheet 22.

Figure 1 is a cross-sectional view showing an example of the structure of a cylindrical cartridge 1 for smoking articles. The cartridge 1 shown in Figure 1 includes a base material 10 containing a filler 21, a filter member 13, and a transfer section 11 provided between the filter member 13 and the base material 10, and has a cylindrical appearance. It may further include a cover member 14 at the end on the side of the base material 10 containing the filler 21. The direction in which the three elements of the base material 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.

Figure 2 is an external view showing an example of the structure of the cartridge 1 of the present invention. As shown in Figure 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.

The transport section 11 is arranged adjacent to the base material 10. The transport section 11 is not particularly limited as long as it is made of a material with excellent heat resistance, and can be made of, for example, silicone. The length of the transport section 11 is preferably 10% to 40% of the total length of the cartridge 1, and more preferably 15% to 30%.

The cartridge 1 shown in Figure 3 is a cross-sectional view showing another embodiment of the structure of a columnar cartridge for smoking articles. 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 exterior sheet 22, and has a columnar appearance.

The substrate 10, support 12, transport unit 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. In addition, by having a configuration with the support 12, the airflow of the aerosol is stabilized, making it easier for the user to inhale the aromatic components.

The transfer section 11 may be formed of a support member 15 that supports a base material 10 containing a filler 21, as is commonly used. In addition, since the cartridge 1 has improved strength against bending, the transfer section 11 may be formed of a sponge, a foam, a fiber aggregate, a porous body, or a rod-shaped object that does not contact the inner surface of the outer shell of the cartridge 1 (see FIG. 1).

The transfer section 11 may also have an airflow hole in the center. 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 for the transfer section 11 to have an airflow hole or a notch on the side.

The exterior sheets 22 have overlapping portions 30 between the exterior sheets 22 and non-overlapping portions 31, and the overlapping portions 30 may extend in a direction inclined relative to the longitudinal direction of the cartridge 1.

4 and 5 are diagrams showing an example of the filler 21 (filled state) of the base material 10. The base material 10 includes the filler 21 filled in the exterior sheet 22. The exterior sheet 22 has an overlapping portion 30 between the exterior sheets 22 and a non-overlapping portion 31, and the overlapping portion 30 extends in a direction inclined with respect to the longitudinal direction of the cartridge 1. The exterior sheet 22 that covers the filler 21 covers the base material 10, the support 12, the transfer portion 11, and the filter member 13, but the filler 21 may be covered with an exterior sheet 22 other than the exterior sheet 22, and the base material 10 may be configured to include a cylindrical exterior portion 20 (see FIG. 6) and the filler 21. This configuration improves the force of holding the filler 21 in the cartridge 1.

In the exterior sheet 22, the overlapping portion 30 extending in a direction inclined to the longitudinal direction can be formed, for example, by preparing a parallelogram exterior sheet 22, rolling it into a cylindrical shape, and gluing both ends to form a loop, so that the glued portion forms 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 inclined to the longitudinal direction of the cartridge 1, making it possible to provide a glued portion extending in the circumferential direction on the exterior sheet 22 of the cartridge 1, which disperses the force of twisting or bending the cartridge 1 by the user, thereby improving the strength of the entire cartridge 1.

Also, as shown in FIG. 6, the overlapping portion 30 may be formed by preparing a tape-like exterior sheet 22 and winding it in a spiral shape so as to overlap to form a columnar object. 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.

Furthermore, as shown in FIG. 7, multiple parallelogram-shaped sheets may be bonded together with only the sides overlapping to form the exterior sheet 22, and then, as shown in FIG. 7, the exterior sheet 22 may be rolled up flat. With this configuration, the strength of the exterior of the cartridge 1 can be improved without changing the production process for flat rolling.

It is preferable that the range of the overlapping portion 30 is 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 exterior sheet 22 constituting the non-overlapping portion 31 and the edge end of the exterior sheet 22 constituting the overlapping portion 30 in the exterior sheet 22. 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 FIG. 6). In the case of a spiral shape in which there are multiple overlapping portions 30, the arithmetic average value is the range. By making the range of the overlapping portion 30 smaller than the range of the non-overlapping portion 31, the amount of the exterior sheet 22 used can be minimized. In addition, 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 ratio of the range of the overlapping portion 30 may be uniform or non-uniform. If 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.

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.

The inner peripheral surface of the exterior sheet 22 may be coated with or impregnated with a fragrance. There are no particular limitations on the fragrance as long as it is one that is generally used in cylindrical cartridges 1 for smoking devices, and examples of such fragrances include tobacco extract, vanillin, chocolate, cocoa, and menthol.

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 keeping the thickness 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 to the longitudinal direction.

From the viewpoint of ease of holding by the user, 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 in a spiral shape in a direction inclined to the longitudinal direction is preferably 5.0 mm or more and 8.0 mm or less. In addition, 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 the diameter of the circumscribing circle with the largest diameter among one or more circles circumscribing the polygon.

The overlapping 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 overlapping portion 30 will be narrower, the adhesive surface will be reduced, and productivity will decrease, 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 extension of the overlapping portion 30 will reduce the overall strength.

The pitch p of the overlapping portion 30 is preferably 10% to 18% of the overall length when the thickness of the exterior sheet 22 is 0.2 mm, for example. By keeping it in this range, the strength can be improved even with a relatively thin exterior sheet 22. Furthermore, for example, when the thickness of the exterior sheet 22 is 0.5 mm, the pitch p is preferably 18% to 50% of the overall length. By keeping it in this range, the strength can be improved without making the entire cartridge 1 too thick.

In one embodiment of the present invention, a cylindrical cartridge 1 for a smoking article includes a filter member 13, a base material 10 including a filler 21, a transport section 11 provided between the filter member 13 and the base material 10, a support 12 supporting the filler 21, and an exterior sheet 22 wound around the base material 10, the transport section 11, the support 12, and the filter member 13 so as to be arranged adjacent to each other in the longitudinal direction of the cartridge 1, and the exterior sheet 22 has a first range 40 along the longitudinal direction and a second range 43 on the filter member 13 side of the first range 40 in the longitudinal direction, as shown in FIG. 9, and the exterior sheet 22 in the first range 40 is wound spirally in a direction inclined to the longitudinal direction, and the exterior sheet 22 in the second range 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 way that suits their respective characteristics, making it possible to use wider components and base materials 10, and when attaching a cigarette to a tobacco heating device, the thickness and strength of the exterior can be set to suit the side that comes into contact with the device and the side that the user holds the cigarette.

The exterior sheet 22 may be configured to have a first overlap portion 41 between the exterior sheets 22 and a first non-overlapping portion 42 in the first range 40, and a second overlap portion 44 between the exterior sheets 22 and a second non-overlapping portion 45 in the second range 43. By having the first overlap portion 41 and the second overlap portion 44, the strength can be further improved in fastening suitable for the characteristics of each member and the base material 10.

It is also 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.

In the first range 40, the range of the first overlapping portion 41 is preferably smaller than the range of the first non-overlapping portion 42. By making the range of the first overlapping portion 41 smaller than the range of the first non-overlapping portion 42, the amount of exterior sheet 22 used can be minimized. In addition, the ratio of the range of the first overlapping 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%. The ratio of the range of the first overlapping portion 41 may be uniform or may be non-uniform in each overlapping portion. When the first overlapping portion 41 and the other portion are the same or the other portion is larger than the first overlapping portion 41, the strength is improved due to the increase in the overlapping portion.

In the second range 43, it is preferable that the range of the second overlap portion 44 is smaller than the range of the second non-overlapping portion 45. In addition, the ratio of the range of the second overlap 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 overlap portion 44 may be uniform or may be non-uniform in each overlap portion. When the second overlap portion 44 and the non-overlapping portion are the same or the non-overlapping portion is larger than the second overlap portion 44, the strength is improved due to the increased overlapping portion.

In addition, 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%.

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

Furthermore, for example, when the thickness of the exterior sheet 22 is 0.2 mm, the pitch p of the first overlap portion 41 is preferably 10% or more and 18% or less of the total length. By setting the pitch p in this range, the strength can be improved even with a relatively thin exterior sheet 22. Furthermore, for example, when the thickness of the exterior sheet 22 is 0.5 mm, the pitch p is preferably 18% or more and 50% or less of the total length. By setting the pitch p in the above range, the strength can be improved without making the entire cartridge 1 too thick.

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%.

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 a tobacco is placed in a tobacco heating device, the thickness and strength of the exterior can be set in a more appropriate range on the side that contacts the device and the side that the user holds the tobacco.

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

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 having 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.

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

When the filling material 21 is in the form of a strip or a sheet, it is preferable that the length of the filling material 21 is approximately equal to the height of the exterior part 20. That is, it is preferable that the length is 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. When the filling material 21 is in the form of a strip, 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. When the filling material 21 is in the form of a sheet, 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. Furthermore, when the filling material 21 is in the form of a granule, 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.

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 passing the mixture through an orifice under pressure to form it into a rod shape, 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.

The non-tobacco materials (aromatic components that produce aroma when heated) that form the filling 21 include, but are not limited to, the following:

The non-tobacco material that can be used in this embodiment is not particularly limited as long as it is a plant other than tobacco. Various parts of the plant 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.

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

The support 12 is formed to support the filling material 21, and is arranged between the transfer section 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%.

The filter member 13 is not particularly limited as long as it is made of a material that prevents the heated filling 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%.

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 further enjoy the aromatic components.

A lid member 14 may be formed on the end surface on the substrate 10 side to prevent the filling 21 from spilling (see FIG. 1). Since the exterior sheet 22 is wound in a spiral shape, the thickness of the outer shell of the cartridge 1 is also increased, and the lid member 14 can 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 the filling 21 from spilling, and can be formed using, for example, the same material as the exterior sheet 22. Among them, 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 combustion regulators, fragrances, pigments, binders, protective materials, oily components, extracts, and antioxidants.

(Production method)
Next, a method for manufacturing the cartridge 1 will be described.

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 transport section 11 provided between the filter member 13 and the substrate 10, and an exterior sheet 22, in which the material of the filler 21, the transport section 11, and the filter member 13 are arranged in this order on the planar exterior sheet 22, the material of the filler 21, the transport section 11, and the filter member 13 are wrapped in the exterior sheet 22, the exterior sheet 22 has overlapping sections 30 between the exterior sheets 22 and non-overlapping sections 31, and the overlapping sections 31 extend in a direction inclined with respect to the longitudinal direction of the cartridge 1.

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

First, the material of the filler 21 will be described. The production of the material of the filler 21 includes a drying and crushing process in which the main raw materials, tobacco material and/or non-tobacco material, are dried and crushed 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.

In the drying and grinding process, the tobacco material and/or non-tobacco material used as the main raw material (e.g., leaves, seeds, dried fruit, stems, bark, roots, etc.) as described above is processed into a specified ground material to prepare a composition. In this case, it is preferable to adjust the moisture content to a level suitable for absorbing or carrying the aerosol former, water, and other components to be added later. In drying, the temperature is preferably 60°C or higher and 80°C or lower. 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 the temperature is 75°C or lower, the loss of the required aromatic components can be further prevented.

It is preferable that the moisture content after drying and pulverization is 5% by mass or less. This makes it easier to turn the material into a slurry in the subsequent process. It is even more preferable that the moisture content is 3% by mass or less. Furthermore, if the moisture content is 0.1% by mass or more, the material can maintain a good compatibility with water, etc. Furthermore, the drying and pulverization process can also include a sieving process for sieving the pulverized material, so that it can be adjusted to the desired particle size before being introduced into the mixing process.

In the preparation process, the raw materials required to create the filling 21 can be prepared.

In the mixing process, a conventional mixer can be used. For example, a mixing device that mixes the raw materials in a mixing tank while applying shear force with a stirring blade is preferably used.

In the filling molding process, the composition for filling 21, which is a mixture of various raw materials, is molded into a thin sheet, which is then cut into strips, sheets, granules, etc., to form filling 21. In this embodiment, a roll mill is prepared to make a thin sheet. The use of a roll mill is preferable because it is possible to compress the material by forcing it between narrow rolls, and to knead and disperse the material by shearing due to the difference in roll speed, while forming a sheet of the desired thickness using a doctor blade. It can also be made using a press roller or a press machine.

In the filling molding step, other means may be used, such as passing the composition for filling 21 through an orifice under pressure to form it. In addition, in the filling molding step, non-tobacco plants, aerosol formers, binders or thickeners, flavor additives, preservatives, or water may be added as necessary.

In this embodiment, it is preferable to use water that has been sterilized or has had microorganisms removed, and it is preferable to use pure water obtained by reverse osmosis or ion exchange, etc.

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

The material of the filling material 21, the transfer part 11, (support 12) and the filter member 13 thus formed are arranged in this order and set on the planar exterior sheet 22. When the material of the filling material 21 is in the form of a strip, it is arranged parallel to the longitudinal direction. The planar exterior sheet 22 has a length for a plurality of cartridges 1. Each component is wrapped in a spiral shape with the exterior sheet 22 in a direction inclined to the longitudinal direction of the cartridge 1 to form the cartridge 1. At this time, by wrapping the exterior sheet 22 while rolling it at an angle, an overlapping portion 30 and a non-overlapping portion 31 are formed, and the overlapping portion 30 may extend in a direction inclined to the longitudinal direction of the cartridge 1. At this time, glue is applied in advance to the area that will become the overlapping portion 30. The overlapping portion 30 becomes a glued portion extending in the circumferential direction, making it easier to form a tube of the exterior sheet 22 with improved strength in the longitudinal and lateral directions, and improving the strength of the entire cartridge 1. When the filler 21 material is in the form of strips, it is preferable that multiple pieces of filler 21 material are arranged along the longitudinal direction of the cartridge 1 in order to form an efficient airflow. Examples of ways to wrap the exterior sheet 22 include 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, but are not limited to these.

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 about 7.0 mm and a length of about 45.0 mm. At this time, a small amount of adhesive may be applied to the base material 10 to fix it to the exterior sheet 22. Also, to improve the design and strength, a covering portion (not shown) wrapped in another sheet may be formed on the outer periphery of the exterior sheet 22.

Next, a method for manufacturing the cartridge 1 in which the material of the filler 21 is wrapped in a separate exterior sheet 22 will be described. The manufacturing method in which the material of the filler 21 is wrapped in a separate exterior sheet 22 to form the exterior body 20 improves the ability of the base material 10 to hold various types of filler 21.

First, the material for the filling 21 formed as described above is placed on a planar exterior sheet 22. The planar exterior sheet 22 has a length equivalent to the length of multiple exterior portions 20.

Next, the material of the filling material 21 is wrapped in a spiral shape with the exterior sheet 22 in a direction inclined to the longitudinal direction of the cartridge 1, forming a cylindrical exterior part 20 filled with the filling material 21. In addition, at this time, by wrapping the exterior sheet 22 while rolling it at an angle, overlapping parts 30 and non-overlapping parts 31 are formed, and the overlapping parts 30 may extend in a direction inclined to the longitudinal direction of the cartridge 1. At this time, glue is applied in advance to the area that will become the overlapping parts 30. The overlapping parts 30 become glued parts extending in the circumferential direction, making it easier to form a tube of the exterior part 20 with improved strength in the longitudinal and lateral directions, and improving the strength of the entire cartridge. When the material of the filling material 21 is in the form of strips, it is preferable that multiple pieces of the material of the filling material 21 are arranged along the longitudinal direction of the cartridge 1 in order to form an efficient airflow.

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

The exterior sheet 22 encases the filling material 21, and the glued columnar shape (roll) is cut to a specified length to produce a cylindrical exterior part 20 with an outer diameter of approximately 6.9 mm and a length of approximately 12.0 mm, for example.

After the formation of the cylindrical exterior part 20 is completed, 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 a process of forming a wound rod with another exterior sheet 22 and a cutting process are performed, and the manufacture of the cartridge 1 is completed. At this time, the base material 10 may be fixed to the other exterior sheet 22 by applying a small amount of adhesive. Also, in order to improve the design and strength, a covering part (not shown) may be formed on the outer periphery of the other exterior sheet 22.

In the case of the shape of the exterior sheet 22 shown in FIG. 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 by flat rolling, and it may be a single-layer type wrapped once, or a multi-layer type wrapped multiple times until it reaches a predetermined thickness.

The exterior sheet 22 encases the filling material 21, and the glued columnar shape (roll) is cut to a specified length to produce a cylindrical exterior part 20 with an outer diameter of approximately 6.9 mm and a length of approximately 12.0 mm, for example.

After the formation of the cylindrical exterior part 20 is completed, the base material 10 having the exterior part 20, the transport part 11, (support 12) and the filter member 13 are adjacent to each other in this order, and a process of forming a wound rod with another exterior sheet 22 is performed, and the manufacture of the cartridge 1 is completed. As an example, the cartridge 1 has an outer diameter of about 7.0 mm and a length of about 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. Also, in order to improve the design and strength, a covering part may be formed on the outer periphery of the other exterior sheet 22.

In one embodiment of the present invention, a cylindrical cartridge 1 for a smoking article includes a filter member 13, a base material 10 containing a filler 21, a transport section 11 provided between the filter member 13 and the base material 10, a support 12, and an exterior sheet 22. The material of the filler 21, the transport section 11, the support 12, and the filter member 13 are arranged in this order on the planar exterior sheet 22, and the material of the filler 21, the transport section 11, the support 12, and the filter member 13 are wrapped in an exterior sheet 22 having a first range 40 along the longitudinal direction and a second range 43 on the filter member 13 side of the first range 40 in the longitudinal direction. In the first range 40, the exterior sheet 22 wraps in a spiral shape in a direction inclined to the longitudinal direction, and in the second range 43, the exterior sheet 22 wraps in a spiral shape in a direction intersecting the longitudinal direction.

Furthermore, the material of the filling material 21, the transport section 11, the support 12, and the filter member 13 are arranged adjacent to each other in this order on the planar exterior sheet 22, and the exterior sheet 22 is rolled at an angle, so that the exterior sheet 22 envelops each of the members to form 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 a first overlapping portion 41 and a first non-overlapping portion 42 between the exterior sheets 22 in a first range 40 along the longitudinal direction of the cartridge 1, and has a second overlapping portion 44 and a second non-overlapping portion 45 between the exterior sheets 22 in a second range 43 along the longitudinal direction, and the first overlapping portion 41 extends in a direction inclined relative to the longitudinal direction, and the second overlapping portion 43 extends in a direction intersecting the longitudinal direction. A cartridge 1 may be manufactured in this manner. Each component is wrapped and tightened with the exterior sheet 22, reducing the risk of misalignment due to differences in attributes, making it possible to reduce the number of processes while maintaining quality.

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 an exterior sheet 22 for each, or may be formed by changing the wrapping direction of a single exterior sheet 22. Furthermore, when prepared separately, the wrapping 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 as shown in FIG. 9, or may be different.

An additional step may be to apply a small amount of adhesive to the lid member 14 and secure it to the end on the substrate side. This step may be performed either before or after the cutting step described above.

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 clear 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 forms incorporating such modifications or improvements can also be included in the technical scope of the present invention.
