Mode for Carrying Out the Invention

[0010] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0011] (First Embodiment) FIG. 1 is a cross-sectional view of a cartridge 1 for a smoking device according to the first embodiment of the present invention. As shown in FIG. 1 the cartridge 1 for a smoking device according to the first embodiment includes a heating element 20, a support 30 and a mouthpiece 40. The heating element 20, the support 30, and the mouthpiece 40 are arranged side by side on the central axis C1. And the heating element 20, the support 30, and the mouthpiece 40 are wound and integrated by a sheet-like outer body 10. The outer body 10 is, for example made of paper.

[0012] Here, the cartridge 1 for a smoking device shown in FIG. 1 has, for example, a diameter of 6.5 to 7.5 mm, a length of 40 to 60 mm. Further, the heating element 20 has a length of 10 to 25 mm Of course, the cartridge for a smoking device may be formed in other dimensions.

[0013] The heating element 20 is formed in a cylindrical shape by winding an aerosol-forming substrate 23, which is a filler, with a sheet-like packaging member 25, and the aerosol-forming substrate 23 is exposed at both ends thereof. That is both ends of the heating element 20 are not covered by a lid member (for example, paper). Note that the packaging member 25 is made of, for example, paper, but any sheet-like member may be used regardless of the material. 25 is made of, for example, paper, but any sheet-like member may be used regardless of the material.

[0014] The aerosol-forming substrate 23 is made from a tobacco plant or a non-tobacco plant, which will be described later in detail. The aerosol-forming substrate 23 is, for example, a bundle of rectangular members. The longitudinal direction of the shaft 14 is aligned along the central axis C1.

[0015] When the aerosol-forming substrate 23 is formed of a strip-shaped member, the cross section perpendicular to the central axis C1 is approximately It is rectangular, and the ratio of the long side to the short side of the cross section is, for example, in the range of 1.5:1 to 30:1. In addition, the length of the aerosol-forming substrate 23 is preferably approximately the same as the length of the object to be heated 20. As an example of the dimensions of the aerosol-forming substrate 23, the long side is preferably 1.5. mm, short side 0.3 mm, length 12 mm.

[0016] Of course, the aerosol-forming substrate 23 is not limited to a strip-shaped member. For example, a rod-shaped member Alternatively, the aerosol-forming substrate 23 may be a powder-like material. The combination of strip-shaped and powder-shaped materials, and the combination of strip-shaped and rod-shaped materials , a combination of rod-shaped members and powder-shaped members, or a combination of strip-shaped members, rod-shaped members and powder-shaped members. In these cases, the composition may be made of a combination of the raw materials of each component. However, if some of the ingredients are different, this is preferable since it improves the aroma and flavor.

[0017] The mouthpiece 40 is a part that constitutes the mouth of the cartridge 1 for a smoking article, and is made of, for example, paper. The mouthpiece 40 is made of cellulose acetate, which removes fine particles. The heated body 20 may include a filter or the like. Some of the fine particles are filtered by the filter of this mouthpiece 40.

[0018] The support 30 is composed of a plurality of granular materials 31. The granular materials 31 are made of, for example, plastic hook particles and are filled inside the outer body 10 sandwiched between the aerosol forming base material 23 and the mouthpiece 40. The shape of the granular material 31 is not particularly limited, and for example, the cross-sectional shape may be round, oval or polygonal, etc. Also, the granular material 31 may be solid or hollow, and its particle size is, for example, 0.5 mm to 1 mm.

[0019] Note that the granular material 31 is not limited to plastic particles, and activated carbon that can remove specific chemical substances (such as tar) mixed in the aerosol, or particles made of inorganic substances such as ceramics and glass may be used, or a mixture of these multiple types of particles may also be used. Furthermore, a remover (such as chitosan) that can remove the above chemical substances (such as aldehydes such as formaldehyde) may be added to a part or all of the plurality of granular materials 31.

[0020] Alternatively, as the granular material 31, it is also possible to use plant-based raw materials such as coffee grounds after extracting coffee or tea leaves after extracting tea. Since these plant-based raw materials are porous and have a high odor-removing effect, a support 30 with an odor-removing effect can be realized. Note that when the plurality of granular materials 31 are made of coffee grounds, the coffee grounds have a small particle size as they are, so it is preferable to use them in a dumpling-like state with starch or the like. Also, when the plurality of granular materials 31 are made of tea leaves, if the aerosol forming base material 23 is composed of tea leaves, air Both the aerosol-forming substrate 23 and the support 30 can be manufactured from the same material.

[0021] The support 30 is a porous structure having a gap S between a plurality of particulate matter 31. The gap S functions as a passage for the aerosol generated by heating the aerosol-forming substrate 23. One end 30a of both ends of the support 30 is the side facing one end 23a of the aerosol-forming substrate 23, and the other end 30b is the side facing the mouthpiece 40. One end 30a of the support 30 abuts on and supports the aerosol-forming substrate 23 when a heating member is inserted, and the other end 30b of the support 30 abuts on and supports the mouthpiece 40.

[0022] FIG. 2 is a cross-sectional view taken along line II-II of FIG. 1. As shown in FIG. 2, at the end 30a of the support 30 facing the aerosol-forming substrate 23, the plurality of particulate matter 31 are adhered to each other using an adhesive 32. Therefore, the strength of the end 30a of the support 30 facing the aerosol-forming substrate 23 is increased, and the end 23a of the aerosol-forming substrate 23 can be firmly supported even when a heating member is inserted.

[0023] Note that not only one end 30a of the support 30 but also the other end 30b and the plurality of particulate matter 31 arranged on the outer peripheral surface side may be partially adhered to each other. Also, if the required support strength of the aerosol-forming substrate 23 is ensured, not all of the particulate matter 31 need to be adhered. Furthermore, all of the particulate matter 31 including the particulate matter 31 on the aerosol-forming substrate 23 side may be adhered to each other. By doing so, the overall strength of the support 30 can be increased. This can be achieved. At this time, all of the gaps S existing between the particulate matters 31 are filled with the adhesive, and the porous structure of the support 30 is damaged, so it is necessary to bond in a state where the gap S through which the aerosol can pass is secured.

[0024] Next, specific examples of the raw materials used as the aerosol-forming substrate 23 will be described. The aerosol-forming substrate 23 is composed of any one or a combination of the following raw materials. It is composed of.

By combining menthol with a water-insoluble crosslinked polymer , the sublimation of menthol can be effectively suppressed, and the flavor of menthol can be maintained for a long time . Here, menthol is not limited to that obtained from natural products, but can also be a synthetic product It is also acceptable to use those containing peppermint, mint, peppermint oil, and other menthol. It is acceptable.

[0035] The flavor additive is provided in the mouthpiece 40, for example, by impregnating the wall portion of the mouthpiece 40. The mode in which the flavor additive is provided in the mouthpiece 40 is not limited to such a mode. For example, by embedding a capsule in which the flavor additive is enclosed in the wall portion of the mouthpiece 40, the flavor additive may be provided in the mouthpiece 40. Alternatively, a capsule in which the flavor additive is enclosed may be disposed between the mouthpiece 40 and the heated body 20. When the flavor additive is enclosed in a capsule, the smoker can break the capsule by pressing it with a finger, and it becomes possible to volatilize the aromatic component of the flavor additive at a desired timing. It is also acceptable. Moreover, when the flavor additive is enclosed in, for example, microcapsules, the enclosed microcapsules may be provided on the heated body 20.

It has. It is.

[0039] In the drying and pulverizing step, in order to use the tobacco plant or non-tobacco plant as the main raw material (for example, leaves, seeds, dried fruits, stems, barks, roots, etc.) as a composition, it is processed into a predetermined pulverized product. At this time, it is preferable to adjust the moisture content to a convenient amount for absorbing or supporting 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 setting it within this range, it is easy to reach the desired moisture content while avoiding the dissipation of the required flavor components. Furthermore, a sieving step for sieving the pulverized product can also be provided in the drying and pulverizing step, and it can be adjusted to the desired particle size and put into the mixing step. It is. It can be.

[0040] In the preparation step, the raw materials necessary for producing the aerosol-forming substrate 23 can be prepared. The aforementioned microcrystalline cellulose is weighed in the preparation step and put into the mixing step. It is input.

[0041] In the mixing step, a normal mixer can be used. For example, a form in which the raw materials in the mixing tank are mixed while applying a shearing force with a stirring blade is preferably used. It is.

[0042] In the filler forming step, a composition in which various raw materials are mixed is formed into a thin sheet, and then cut to form a strip-shaped or rod-shaped aerosol forming substrate 23 by cutting. In this embodiment To make a thin sheet, a plurality of roll mills are prepared. When using a plurality of roll mills By being pushed between narrow rolls, compression and shearing due to the roll speed difference While performing kneading, dispersion, etc., it is possible to form a sheet of a desired thickness with a doctor blade which is preferable. It can also be produced using a press roller or a press machine .

[0043] Also, to obtain a powdery or granular aerosol forming substrate 23, it is preferable to appropriately grind or classify the above composition. The average particle size of the powdery or granular aerosol forming substrate 23 is preferably, for example, 0.1 to 3.0 mm, and more preferably 0.5 mm or less . The average particle size is determined by, for example, the sieving method described in JIS K 0069:1992 . That is, this average particle size is obtained by integrating the mass from the sieve with the larger mesh size for the test results of a plurality of sieves, and refers to the diameter corresponding to 50% of the mass . Also, the particle size at the integrated value of 50% in the particle size distribution determined by the laser diffraction / scattering method may be used as the average particle size . %

[0047] (How to use smoking cartridges) A method of using the cartridge 1 for smoking articles will be described. FIG. 3 shows the cartridge 1 for smoking articles. 1 is a cross-sectional view of the cartridge 1 inserted into a smoking article 70. The smoking article 70 is used by being attached to the smoking article cartridge 1. The insertion part 72 is provided with a needle-shaped or blade-shaped heating part 75. When the cartridge 1 for a smoking article is inserted into the insertion portion 72, the heating portion 75 generates heat. In this state, the smoker When the subject holds the mouthpiece 40 in his mouth and inhales, the aerosol enters the gap S of the support 30, the mouthpiece The gas flows through the nozzle 40 and then into the smoker's mouth.

[0048] According to the smoking implement cartridge 1 according to the first embodiment configured as described above, the following effects can be achieved.

[0049] Since the support 30 is composed of a plurality of granular materials 31, the manufacturing is simpler compared to conventional resin molded products, and the manufacturing cost of the support 30 can be reduced.

[0050] Further, the support 30 is a porous structure having a gap S between the plurality of granular materials 31, and since the gap S functions as a passage for the aerosol to pass through, the aerosol is cooled while being streamlined by the gap S, and the aroma and taste of the aerosol are improved.

[0051] Also, a plurality of granular materials 31 are arranged between the aerosol forming substrate 23 and the mouthpiece 40, and since a plurality of granular materials 31 arranged on the side facing the aerosol forming substrate 23 are adhered to each other, the end portion 23a of the aerosol forming substrate 23 can be firmly supported. Note that not only one end portion 30a of the support 30, but also the other end portion 30b and a plurality of granular materials 31 arranged on the outer peripheral surface side may be partially adhered to each other, or all of the granular materials 31 may be adhered to each other.

[0052] (Second Embodiment) Next, the smoking implement cartridge according to the second embodiment will be described. The smoking implement cartridge 2 according to the second embodiment basically has the same configuration as the smoking implement cartridge 1 according to the first embodiment, but is different in that the support 30 is composed of a mixture of a first granular material 33 and a second granular material 34. Therefore, in the following description, the description will focus on this difference, and the description overlapping with the first embodiment will be omitted.

[0053] ​​ FIG. 4 is a cross-sectional view of the smoking implement cartridge 2 according to the second embodiment. As shown in FIG. 4 , the support 30 is composed of a first granular material 33 made of plastic particles or the like and a second granular material 34 made of capsules. In FIG. 4, the first granular material 33 and the second granular material 34 are shown in white and hatched, respectively, for easy recognition and distinction.

[0054] The first granular material 33 is made of plastic particles or inorganic substances, similar to the granular material 31 that constitutes the support 30 of the smoking implement cartridge 1 according to the first embodiment. The second granular material 34 is composed of capsules in which a flavor additive is encapsulated in a shell layer. The shell layer of the capsule is configured to melt with heat during heating and release the internal flavor additive to the outside, but the internal flavor additive may also be released to the outside by crushing it by hand. The flavor additive encapsulated in the capsules of the second granular material 34 includes flavor components such as spice components and taste components such as tea leaves, and may also include tar removal components, aerosol formers, and the like.

[0055] The shape of the second granular material 34 is not particularly limited, such as a sphere or a polyhedron, but it is preferably a capsule having a shape similar to that of the first granular material 33. Also, the mixing ratio of the first granular material 33 and the second granular material 34 is not particularly limited, but since the second granular material 34 has a structure that melts when heated, it is preferably contained at least half or more of the first granular material 33.

[0056] According to the smoking implement cartridge 2 according to the second embodiment configured as described above, as described above ​​​​​​​​​The same effects as those of the first embodiment can be achieved. Also, among the first granular material 33 and the second granular material 34 that constitute the support 30, the second granular material 34 is a capsule encapsulating a flavor additive, and since this capsule is configured to melt by heat during heating and release the internal flavor additive to the outside, during smoking, the flavor additive encapsulated in the capsule of the second granular material 34 and the first granular material 33 are mixed, so that a new flavor, aroma, or complex flavor and aroma can be tasted. Among the first granular material 33 and the second granular material 34 that constitute the support 30, the second granular material 34 is a capsule encapsulating a flavor additive. Since this capsule is configured to melt by heat during heating and release the internal flavor additive to the outside, during smoking, the flavor additive encapsulated in the capsule of the second granular material 34 and the first granular material 33 are mixed, so that a new flavor, aroma, or complex flavor and aroma can be tasted.

[0057] Next, a modified example of the smoking implement cartridge 2 according to the second embodiment will be described.

[0058] (Modified example) FIG. 5 is a cross-sectional view showing a state where the smoking implement cartridge 2-1 according to the modified example is inserted into the smoking implement 70. As shown in FIG. 5, the smoking implement cartridge 2-1 according to the modified example has a shorter axial dimension of the aerosol-forming base material 23, and other configurations are the same as those of the smoking implement cartridge 2 according to the second embodiment shown in FIG. 4. When the smoking implement cartridge 2-1 according to the modified example is inserted into the heat-type smoking implement 70, the heating part 75 penetrates through the short aerosol-forming base material 23 and enters the inside of the support 30, so that the first granular material 33 and the second granular material 34 that constitute the support 30 come into contact with the heating part 75. And when the heating part 75 generates heat in this state, the capsule of the second granular material 34 melts due to the heat of the heating part 75 and the internal flavor additive is released to the outside. In the smoking implement cartridge 2-1 according to the modified example configured in this way, since the heat of the heating part 75 is directly transmitted to the second granular material 34 composed of the capsule, the capsule of the second granular material 34 can be more surely melted. The axial dimension of the aerosol-forming base material 23 is set to be short, and other configurations are the same as those of the smoking implement cartridge 2 according to the second embodiment shown in FIG. 4.

[0059] When the smoking implement cartridge 2-1 according to the modified example is inserted into the heat-type smoking implement 70, since the heating part 75 penetrates through the short aerosol-forming base material 23 and enters the inside of the support 30, the first granular material 33 and the second granular material 34 that constitute the support 30 come into contact with the heating part 75. And when the heating part 75 generates heat in this state, the capsule of the second granular material 34 melts due to the heat of the heating part 75 and the internal flavor additive is released to the outside. In the smoking implement cartridge 2-1 according to the modified example configured in this way, since the heat of the heating part 75 is directly transmitted to the second granular material 34 composed of the capsule, the capsule of the second granular material 34 can be more surely melted. When the heating part 75 generates heat in this state, the capsule of the second granular material 34 melts due to the heat of the heating part 75 and the internal flavor additive is released to the outside. In the smoking implement cartridge 2-1 according to the modified example configured in this way, since the heat of the heating part 75 is directly transmitted to the second granular material 34 composed of the capsule, the capsule of the second granular material 34 can be more surely melted.​ 。

[0060] (Third Embodiment) Next, the cartridge for a smoking implement according to the third embodiment will be described. Regarding the cartridge for a smoking implement according to the third embodiment 3 is basically the same in configuration as the cartridge 1 for a smoking implement according to the first embodiment, but the support 30 has a cylindrical member filled with a plurality of granular materials 31 which is different.

[0061] FIG. 6 is a cross-sectional view of the cartridge 3 for a smoking implement according to the third embodiment. As shown in FIG. 6 , the support 30 has a cylindrical member 35 covered with an outer body 10, and a plurality of granular materials 31 are filled inside the cylindrical member 35. The cylindrical member 35 is formed by winding a sheet-like member made of, for example, paper into a cylindrical shape, but a material other than paper may also be used. The cylindrical member 35 is interposed between the aerosol-forming base material 23 and the mouthpiece 40, and by abutting against the end face of the packaging member 25 covering the aerosol-forming base material 23, the axial movement of the aerosol-forming base material 23 is restricted.

[0062] According to the cartridge 3 for a smoking implement according to the third embodiment configured as described above, the same effects as those of the first embodiment described above can be achieved. Further, since the support 30 has a cylindrical member 35 filled with a plurality of granular materials 3 1 and this cylindrical member 35 restricts the axial movement of the aerosol-forming base material 23, when inserting the cartridge 3 for a smoking implement into the smoking implement 70 , the position of the aerosol-forming base material 23 is prevented from shifting. Also, since the outer body 10 is supported by the outer peripheral surface of the cylindrical member 35, the diameter when gripping the cartridge 3 for a smoking implement with fingers can be prevented from deforming in the radial direction.

[0063] ​​​​​ Note that the present invention is not limited to the above-described embodiments, and various modifications are possible without departing from the gist of the present invention. All technical matters included in the technical idea described in the claims are the subject of the present invention. The above-described embodiments show preferred examples. However, those skilled in the art can realize various alternative examples, modification examples, variation examples, or improvement examples from the content disclosed

[0064] in this specification, and these are included in the technical scope described in the appended claims. For example, in the cigarette cartridge 3 according to the third embodiment, the plurality of granular materials 31 filled in the cylindrical member 35 are not particularly limited, and may be composed of a single type such as plastic particles or inorganic substances as in the first embodiment, or may be a mixture containing capsules as in the second embodiment. Further, the cylindrical member 35 filled with the plurality of granular materials 31 and the packaging member 25 covering the aerosol-forming base material 23 do not necessarily have to be separate bodies, and they may be integrally formed. Further, the plurality of granular materials 31 may be stored in a storage member such as a case in advance, and when this storage member is wrapped with the cylindrical member 35 or the cylindrical member 35 is omitted, this storage member may be wrapped with the outer body 10. Furthermore, the packaging member 25 and the cylindrical member 35 may be omitted, and the aerosol-forming base material 23, the plurality of granular materials 31, and the mouthpiece 40 may be wrapped with the outer body 10. In this case, after wrapping the aerosol-forming base material 23 with the outer body

[0065] 10, the plurality of granular materials 31 may be filled so as to fall inside the outer body 10, and finally, the mouthpiece 40 may be inserted into the outer body 10 to manufacture the cigarette cartridge.
