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 line with the trend toward smoking cessation, electronic cigarettes have become popular. These products allow users to enjoy tobacco without using a flame by heating a cylindrical smoking device cartridge containing tobacco components and inhaling the vaporized tobacco components. Such cartridges are typically constructed with a filter element, a base material containing a filler containing tobacco components, a support element between the filter element and the base material that supports the base material, and an exterior sheet that wraps the components flat into a single cylindrical shape and adheres and secures the longitudinal ends with glue or the like (see Patent Document 1).

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 reach the user's mouth (see Patent Document 1, Figure 4).

Japanese Patent Application Laid-Open No. 2019-000094

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 aligned in a straight line in the longitudinal direction, vulnerable to bending and sometimes causing peeling or tearing.

Furthermore, when packaging cartridges in exterior sheets, differences in the rigidity, hardness, strength, and other attributes of each component and substrate, as well as their outer diameters, make it difficult to roll flat without gaps, resulting in longitudinal misalignment of the components and substrates, creating gaps. Gaps not only reduce the quality of the cigarette itself, but also affect productivity and strength, necessitating multiple processes, such as wrapping each component and substrate separately with an exterior sheet.

The present invention was made in light of these circumstances, and its purpose is to provide a cylindrical cartridge for a smoking article, and a manufacturing method thereof, which 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 extensive research in view of the above problems, and as a result have found that the above problems can be solved by the cartridge of the following aspect, which has led to the completion of the present invention.
Specifically, the present invention provides the following:

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. Note that in the description of the drawings, identical elements will be 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 sake of explanation, some parts may be exaggerated.

In addition, in this specification, "smoking" generally refers to inhaling smoke containing nicotine, tar, etc., which is produced by burning or heating tobacco leaves of the Nicotiana genus in the Solanaceae family or materials containing tobacco components. However, 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.

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 disposed between the substrate 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 a smoking article. The cartridge 1 shown in Figure 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, giving it 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 one another 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 spirally wound in a direction inclined relative to the longitudinal direction of the cartridge 1. By spirally winding the exterior sheet 22, the strength of the cartridge 1 against bending is improved.

The transfer section 11 is arranged adjacent to the base material 10. There are no particular restrictions on the material of the transfer section 11 as long as it has excellent heat resistance, and it can be made using silicone, for example. 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%.

The cartridge 1 shown in Figure 3 is a cross-sectional view showing another embodiment of the structure of a cylindrical cartridge for a smoking article. The 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 the substrate 10, and an exterior sheet 22, and has a cylindrical appearance.

The substrate 10, support 12, transfer 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. Furthermore, the inclusion of the support 12 stabilizes the aerosol airflow, making it easier for the user to inhale the aromatic components.

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

The transfer section 11 may also have an airflow hole in the center. The presence of this 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 with an airflow hole or cutout 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 be configured to extend in a direction inclined relative to the longitudinal direction of the cartridge 1.

Figures 4 and 5 show an example of the filler 21 (filled state) in the substrate 10. The substrate 10 includes the filler 21 filled within an exterior sheet 22. The exterior sheet 22 has overlapping portions 30 and non-overlapping portions 31 between the exterior sheets 22, with the overlapping portions 30 extending 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, support 12, transfer unit 11, and filter member 13. However, the filler 21 may also be covered with a separate exterior sheet 22, and the substrate 10 may be configured to include a cylindrical exterior unit 20 (see Figure 6) and the filler 21. This configuration improves the cartridge 1's ability to retain the filler 21.

In the exterior sheet 22, the overlapping portion 30 extending in a direction oblique to the longitudinal direction can be formed, for example, by preparing a parallelogram-shaped exterior sheet 22, rolling it into a cylindrical shape, and gluing both ends to form a loop, with the glued portion serving as the overlapping portion 30. The exterior sheet 22 has overlapping portions 30 between the exterior sheets 22 and non-overlapping portions 31. The overlapping portions 30 extend in a direction oblique to the longitudinal direction of the cartridge 1, making it possible to provide a circumferentially extending glued portion on the exterior sheet 22 of the cartridge 1. This distributes the force of twisting or bending the cartridge 1 by the user, improving the overall strength of the cartridge 1.

Also, as shown in Figure 6, the overlapping portion 30 may be formed by preparing a tape-like exterior sheet 22 and spirally winding it so that it overlaps, forming a columnar structure. By making the overlapping portion 30 spiral, a spiral step can be provided on the inner surface of the exterior sheet 22. This step creates a smooth airflow for the aerosol, improving the smoking taste and flavor and increasing the efficiency of exhalation.

Furthermore, as shown in Figure 7, multiple parallelogram-shaped sheets may be glued together with only their sides overlapping to form the exterior sheet 22, and then, as shown in Figure 7, the exterior sheet 22 may be rolled up flat. This configuration can improve the strength of the exterior of the cartridge 1 without changing the flat-rolling production process.

The overlapping portion 30 is preferably smaller than the non-overlapping portion 31. Here, 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 non-overlapping portion 31 refers to the value obtained by subtracting the overlapping portion 30 from the pitch p (see FIG. 6). In the case of a spiral having multiple overlapping portions 30, the arithmetic mean value of the overlapping portions 30 is used. By making the overlapping portion 30 smaller than the non-overlapping portion 31, the amount of exterior sheet 22 used can be minimized. Furthermore, the ratio 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 overlapping portion 30 may be uniform or non-uniform. 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.

The outer sheet 22 can be made of any commonly used material without any particular restrictions, such as a thermally conductive 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 surface of the exterior sheet 22 may be coated with or impregnated with a fragrance. There are no particular restrictions on the fragrance, as long as it is one that is generally used in cylindrical cartridges 1 for smoking devices, and examples include tobacco extract, vanillin, chocolate, cocoa, menthol, etc.

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 relative to the longitudinal direction.

From the perspective of ease of holding for the user, the average outer diameter d of the exterior part 20 (see Figure 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. Note that, in the case of the cartridge 1, "outer diameter" refers to 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, a cartridge 1 is also considered to have a polygonal cross section perpendicular to the longitudinal direction, and the "outer diameter" refers to the diameter of the largest circumscribing circle 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 narrow, 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 components and base material 10 that make up the cartridge 1 without gaps, and the extended overlapping portion 30 will reduce the overall strength.

Furthermore, the pitch p of the overlap portion 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 keeping it within this range, the strength can be improved even with a relatively thin exterior sheet 22. Furthermore, for example, when the paper thickness of the exterior sheet 22 is 0.5 mm, the pitch p is preferably 18% to 50% of the total length. By keeping it within 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 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 outer sheet 22 wound around the substrate 10, the transfer section 11, the support 12, and the filter member 13 so that they are adjacent to each other in the longitudinal direction of the cartridge 1, and as shown in Figure 9, the outer 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 outer sheet 22 in the first region 40 is wound spirally in a direction inclined to the longitudinal direction, and the outer 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 way that suits their respective characteristics, allowing for the use of wider components and base materials 10. Furthermore, when inserting a tobacco into a tobacco heating device, the thickness and strength of the exterior can be tailored to suit the side that comes into contact with the device and the side that the user holds the tobacco.

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

It is also preferable that the second range 43 includes the range of the end on the side where the filter member 13 is located. This configuration allows the cigarette to be partially provided with strength suitable for when the user holds or bites down on the cigarette.

In the first region 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. Furthermore, 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 across the overlapping portions. When the first overlapping portion 41 and the non-overlapping portion are the same or larger than the first overlapping portion 41, the increased overlapping portion improves strength.

In the second range 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 in each overlapping portion. When the second overlapping portion 44 and the non-overlapping portion are the same or when the non-overlapping portion is larger than the second overlapping portion 44, the strength is improved due to the increased overlapping portion.

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%.

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, if the thickness of the exterior sheet 22 is 0.2 mm, the pitch p of the first overlap portion 41 is preferably 10% to 18% of the total length. By keeping it within this range, it is possible to improve the strength of even a relatively thin exterior sheet 22. Furthermore, for example, if the thickness of the exterior sheet 22 is 0.5 mm, it is preferable that the pitch p be 18% to 50% of the total length. By keeping it within this range, it is possible to improve the strength of the cartridge 1 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%. By adopting this 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 both the side that comes into contact with the device and the side that the user holds the tobacco.

The exterior sheet 22 may be made up of a single sheet or multiple sheets that are at least partially overlapped to form overlapping portions 30 and non-overlapping portions 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 at least partially overlapped, the overlapping portions 30 and non-overlapping portions 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.

Furthermore, it is preferable that the outer sheet 22 includes a covering portion (not shown) that covers the outer periphery. The covering portion can improve 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 (Figure 4), or may be in the form of a sheet (Figure 5), chips, a paste, sawdust, or powder (not shown). Here, powder includes powder, fine particles, fine grains, and granules. Since the overlapping portion 30 extends in a direction oblique to the longitudinal direction of the cartridge 1, it becomes easier to form a cylindrical exterior 20 with improved strength in both the longitudinal and lateral directions, enabling the use of fillers 21 in a variety of shapes.

When the filler 21 is in the form of a strip or sheet, it is preferable that the length of the filler 21 be approximately equal to the height of the exterior part 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 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. Furthermore, when the filler 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 filler 21 is in the form of particles, 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.

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

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

The non-tobacco materials that can be used in this embodiment are not particularly limited as long as they are from plants 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.

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

The support 12 is formed to support the filler 21 and is arranged between the transfer section 11 and the filter member 13. The presence of the support 12 allows for smoother insertion of the cartridge 1 into the electronic cigarette body, prevents bending of the cartridge 1, and improves operability. The length of the support 12 is preferably between 10% and 40% of the total length of the cartridge 1, and more preferably between 15% and 30%.

The filter member 13 can be made of any 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 aerosol smoke and aromatic components, allowing the user to enjoy a more comfortable smoking experience. The length of the filter member 13 is preferably between 12% and 60% of the total length of the cartridge 1, and more preferably between 15% and 45%.

The filter member 13 may have multiple holes (not shown) evenly spaced around its circumference to make it easier for the user to inhale the aerosol. As the aerosol cools down along with the outside air that flows in through the holes in the filter member 13, the finer aerosol particles are dispersed well in the user's inhaled air, allowing for even greater enjoyment of the aromatic components.

A lid member 14 may be formed on the end surface on the substrate 10 side to prevent spillage of the filler 21 (see Figure 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 may be made of any material that prevents spillage of the filler 21. For example, it may be made 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 due to 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 ingredients, extracts, and antioxidants.

(Manufacturing 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 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), and an exterior sheet (22), and is manufactured by a method in which the material of the filler (21), the transfer section (11), and the filter member (13) are arranged in this order on the planar exterior sheet (22), and the material of the filler (21), the transfer section (11), and the filter member (13) are wrapped in the exterior sheet (22), the exterior sheet (22) has overlapping portions (30) between the exterior sheets (22) and non-overlapping portions (31), and the overlapping portions (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, misalignment due to differences in attributes is reduced, making it possible to reduce the number of processes while maintaining quality.

First, the material for filler 21 will be described. The production of filler 21 material involves a drying and grinding process in which the tobacco and/or non-tobacco materials that serve as the main raw materials are dried, ground, and weighed; a preparation process in which other raw materials are pre-treated and weighed; a mixing process in which the raw materials are mixed to form a composition for filler 21; and a filler 21 molding process in which the composition for filler 21 is molded.

In the drying and grinding process, the tobacco and/or non-tobacco material (e.g., leaves, seeds, dried fruit, stems, bark, roots, etc.) serving as the primary raw material is ground into a desired 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 components to be added later. The drying temperature is preferably between 60°C and 80°C. This range makes it easier to achieve the desired moisture content while avoiding the loss of essential aroma components. Temperatures of 65°C or higher make it even easier to achieve the desired moisture content, while temperatures of 75°C or lower further prevent the loss of essential aroma components.

It is preferable that the moisture content after drying and pulverization be 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 ensures 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.

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

A conventional mixer can be used in the mixing process. For example, a mixing device that applies shear force to the raw materials in a mixing tank using a stirring blade is preferably used.

In the filler molding process, the composition for filler 21, which is a mixture of various raw materials, is molded into a thin sheet and then cut into strips, sheets, granules, etc. to form filler 21. In this embodiment, a roll mill is used to create thin sheets. 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, allowing for mixing and dispersion, while a doctor blade can be used to create a sheet of the desired thickness. It is also possible to create fillers using a press roller or press.

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

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 with a rotating blade, or the like, to become the material for filling 21. 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.

The filler 21 material, transfer section 11, (support 12), and filter member 13 formed in this manner 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 equivalent to that of 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. By wrapping the exterior sheet 22 while obliquely wrapping, overlapping portions 30 and non-overlapping portions 31 are formed. The overlapping portions 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 portions 30. The overlapping portions 30 become glued portions extending circumferentially, making it easier to form a tube of the exterior sheet 22 with improved strength in the longitudinal and lateral directions, thereby improving the overall strength of the cartridge 1. When the filler 21 material is strip-shaped, it is preferable that multiple pieces of filler 21 material be arranged along the longitudinal direction of the cartridge 1 in order to create an efficient airflow. Methods for wrapping the exterior sheet 22 include, but are not limited to, a method in which each component is fixed and the exterior sheet 22 wraps around them, or a method in which the feed of the exterior sheet 22 is fixed and each component rotates.

The manufacture of the cartridge 1 is completed through the process of forming a wound rod from the exterior sheet 22 and the cutting process. 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, a small amount of adhesive may be applied to the base material 10 to secure it to the exterior sheet 22. Furthermore, to enhance the design or increase strength, a covering portion (not shown) wrapped in another sheet may be formed around the outer periphery of the exterior sheet 22.

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

First, the filler material 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 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, making it easier to form 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.

Methods of wrapping the outer sheet 22 include, but are not limited to, 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 rotates.

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

Once the cylindrical exterior portion 20 has been formed, the base material 10 bearing the exterior portion 20, the transfer portion 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, completing 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. Additionally, to enhance the design or increase strength, a covering portion (not shown) may be formed around the outer periphery of the other exterior sheet 22.

Furthermore, in the case of the shape of the exterior sheet 22 shown in Figure 8, overlapping portions 30 and non-overlapping portions 31 can be formed by flat winding. There are no particular limitations on how the exterior sheet 22 is wrapped flat, and it can be a single-layer type wrapped only once, or a multi-layer type wrapped multiple times until it reaches a predetermined thickness.

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

Once the cylindrical exterior portion 20 has been formed, the base material 10 bearing the exterior portion 20, the transfer portion 11, (support body 12), and the filter member 13 are arranged adjacent to each other in this order, and a process for 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 will have 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 base material 10 to secure it to the other exterior sheet 22. Additionally, to enhance the design or increase strength, a covering portion may be formed around 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 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 filler 21 material, transfer section 11, support 12, and filter member 13 are arranged in this order on the planar exterior sheet 22, and the filler 21 material, transfer section 11, support 12, and 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 inclined relative to the longitudinal direction, and in the second region 43, the exterior sheet 22 wraps spirally in a direction intersecting the longitudinal direction.

Furthermore, by arranging the filler material 21, the transfer section 11, the support 12, and the filter member 13 adjacent to each other in this order on a planar exterior sheet 22 and then rolling the exterior sheet 22 at an angle, the exterior sheet 22 envelops each component, forming 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; in a first range 40 along the longitudinal direction of the cartridge 1, the exterior sheet 22 has a first overlapping portion 41 and a first non-overlapping portion 42 between the exterior sheets 22; and in a second range 43 along the longitudinal direction, the exterior sheet 22 has a second overlapping portion 44 and a second non-overlapping portion 45 between the exterior sheets 22; 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, so that a cartridge 1 may be manufactured. Because each component is wrapped and tightened by the exterior sheet 22, misalignment due to differences in attributes is reduced, making it possible to reduce the number of processes while maintaining quality.

The first overlap portion 41 of the first region 40 and the second overlap portion 43 of the second region 43 may be formed separately by preparing an outer sheet 22 for each, or may be formed by changing the wrapping direction of a single outer sheet 22. Furthermore, if prepared separately, the wrapping directions for forming the first overlap portion 41 of the first region 40 and the second overlap portion 43 of the second region 43 may be the same as or different from each other, as shown in Figure 9.

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.

The present invention has been described above using embodiments, but 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 within the technical scope of the present invention.
