Description

Technical Field

[0001] The present invention relates to a cartridge for a smoking device.

Background Art

[0002] In recent years, tobacco products that heat a tobacco cartridge containing tobacco components without using a flame and inhale the vaporized tobacco components have been widely known. Also, due to the diversification of preferences, cartridge products for enjoying the aroma and taste of plants that do not contain tobacco components, similar to tobacco, without using a flame have begun to be known.

[0003] For example, Patent Document 1 describes an electronic tobacco cartridge having a configuration in which "long tobacco fillers are bundled and the outer peripheral portion is wound with a sheet-like wrapper, and the tobacco fillers are formed such that in a cross-section orthogonal to the length direction, the dimension in the long-side direction is longer than the dimension in the short-side direction, and the outermost tobacco filler in contact with the wrapper faces in a direction in which the long-side direction substantially follows the circumferential direction or in a direction other than the direction in which the long-side direction substantially follows the circumferential direction, and the number of tobacco fillers facing in a direction in which the long-side direction substantially follows the circumferential direction is larger than the number of tobacco fillers facing in a direction other than the direction in which the long-side direction substantially follows the circumferential direction."

Embodiments for Carrying Out the Invention

[0011] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0012] (First Embodiment) FIG. 1 is a cross-sectional view of a cartridge for a smoking device according to a 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 member 30, a transfer member 39, and a mouthpiece 40. The heating element 20, the support member 30, the transfer member 39, and the mouthpiece 40 are arranged side by side on a central axis C1. The heating element 20, the support member 30, the transfer member 39, and the mouthpiece 40 are wound and integrated by a sheet-like outer member 10. The outer member 10 is made of, for example, paper.

[0013] Here, the cartridge 1 for a smoking device shown in FIG. 1 is formed, for example, with a diameter of 6.5 to 7.5 mm and a length of 40 to 60 mm. The heating element 20 has a length of 10 to 25 mm. Of course, the cartridge 1 for a smoking device may be formed with other dimensions.

[0014] The heating element 20 is formed in a cylindrical shape by winding a filler 23 with a sheet-like packaging member 25, and the filler 23 is exposed at both ends thereof. That is, both ends of the heating element 20 are not covered with a lid member (for example, paper). The packaging member 25 is made of, for example, paper, but the material is not limited as long as it is a sheet-like member.

[0015] The filler 23 is configured by filling a large number of members made of a tobacco plant or a non-tobacco plant, which will be described in detail later, and includes a plurality of first smoking materials 21 and a plurality of second smoking materials 22. The second smoking material 22 may be included at least one in the filler 23.

[0016] As will be described in detail later, the first smoking material 21 is composed of a strip-shaped or rod-shaped member, and the second smoking material 22 is composed of a powdery or granular member (see FIGS. 2 and 3). The plurality of first smoking materials 21 are arranged in a bundle such that their longitudinal directions are along the central axis C1, and the plurality of second smoking materials 22 are arranged in a first gap 51 formed between the plurality of first smoking materials 21 and / or a second gap 52 formed between the first smoking material 21 and the packaging member 25 (see FIG. 4).

[0017] The mouthpiece 40 constitutes the suction port of the smoking implement cartridge 1 and is formed using, for example, paper or the like. Further, the mouthpiece 40 may include a cellulose acetate filter or the like that removes fine particles. A part of the fine particles in the water vapor or aerosol generated by the heating element 20 is filtered by the filter of this mouthpiece 40.

[0018] The support member 30 is, for example, a columnar member formed using silicone, and a flow path 35 penetrating along the longitudinal direction is formed inside thereof. In the present embodiment, one flow path 35 is provided in the center, but the number and the location where the flow path 35 is formed are not limited, and the space between the outer peripheral portion of the support member 30 and the packaging member 25 can be used as the flow path 35. The support member 30 is disposed between the heating element 20 and the mouthpiece 40 and restricts the axial movement of the heating element 20. Further, the support member 30 guides the aerosol generated by the heating element 20 to the mouthpiece 40 through the flow path 35. The aerosol is cooled as it flows through the flow path 35 and is sucked into the smoker's mouth through the mouthpiece 40. The support member 30 is not limited to a columnar member and can be in various forms. For example, a sheet of paper or polymer formed into a sheet shape and wound, or a material made of a sponge-like porous body can be used instead.

[0019] Also, in the present embodiment, a partition member 50 is provided between the heating element 20 and the support member 30, and the heating element 20 and the support member 30 are in contact with each other through the partition member 50. Examples of the partition member 50 include a highly breathable filter, paper, and the like. By providing such a partition member 50, it is possible to prevent the heating element 20 from moving within the smoking implement cartridge 1 due to the influence of logistics during transportation or the like. Of course, a configuration without the partition member 50 may also be adopted.

[0020] The transfer member 39 cools the aerosol flowing in the direction of the mouthpiece 40. As the transfer member 39, a rolled paper or a crimped polymer sheet or the like can be used. The transfer member 39 is arranged such that its longitudinal direction is along the longitudinal direction of the smoking implement cartridge 1. Note that the transfer member 39 can be omitted to reduce the number of components. When the transfer member 39 is omitted, the air permeability is improved, and the generated aerosol easily flows downstream, so that the smoker can easily inhale the aromatic component.

[0021] In the case of a configuration in which the transfer member 39 is omitted, a mouthpiece 40 having a longer length in the longitudinal direction of the smoking implement cartridge 1 may be configured to be adjacent to the support member 30. In that case, for example, the cellulose acetate filter of the mouthpiece 40 can also function as a cooler.

[0022] As another example, the transfer member 39 can be omitted and a configuration can be adopted in which a gap is provided between the support member 30 and the mouthpiece 40. In that case, the aerosol passing flow can alternate in the gap, and the aerosol can flow to the mouthpiece 40 as a homogenized aerosol after once undergoing temporal and spatial convection in the gap.

[0023] Furthermore, since the exterior member 10 is configured to cover the heating element 20, the partition member 50, the support member 30, the transfer member 39, and the mouthpiece 40 from the outside, the airflow of the aerosol is stabilized, and the smoker can easily inhale the aromatic component.

[0024] Next, the shapes of the first smoking material 21 and the second smoking material 22 that constitute the filling 23 will be described with reference to FIGS. 2 and 3. FIG. 2 is a diagram showing the outer shape of the first smoking material 21, and FIG. 3 is a diagram showing the outer shape of the second smoking material 22.

[0025] As shown in FIG. 2, the first smoking material 21 is composed of a strip-shaped member having a substantially rectangular (rectangular) cross section perpendicular to the central axis C2. The ratio of the long side a to the short side b is preferably in the range of, for example, 1.5:1 to 30:1. Also, the length c is preferably substantially the same as the length of the heating element 20. As an example of the dimensions of the first smoking material 21, the long side a is 1.5 mm, the short side b is 0.3 mm, and the length c is 12 mm. When the first smoking material 21 is formed of a rod-shaped member, the ratio of the long side a to the short side b of the cross section is preferably in the range of 1:1 to 1.5:1. For example, the long side a is 0.6 mm, the short side b is 0.4 mm, and the length c is 12 mm. The first smoking material 21 has an adhesive or the like attached thereto as will be described later, and its surface has adhesiveness.

[0026] On the other hand, the second smoking material 22 is formed in a powder or granular form. The average particle diameter d of the plurality of second smoking materials 22 is equal to or less than the long side a of the first smoking material 21, and in this embodiment, it is, for example, 0.5 mm.

[0027] FIG. 4 is a cross-sectional view taken along line IV-IV of FIG. 1, that is, a cross-sectional view obtained by cutting the filling 23 along a plane perpendicular to the central axis C1. As shown in FIG. 4, the second smoking material 22 is disposed in a first gap 51 formed between the first smoking material 21 and the first smoking material 21. The second smoking material 22 is also disposed in a second gap 52 formed between the packaging member 25 and the first smoking material 21. That is, in this embodiment, the interior of the packaging member 25 is filled with a large number of first smoking materials 21, and the first gap 51 and the second gap 52 are filled with a large number of second smoking materials 22.

[0028] Here, in this embodiment, the content of the first smoking material 21 in the filling 23 is 50 to 95% by mass, preferably 65 to 75% by mass. And the density of the filling 23 is 295 to 675 mg / cm3, preferably 500 to 675 mg / cm3. The reasons for setting the content of the first smoking material 21 and the density of the filling 23 within the above numerical ranges will be described below.

[0029] For example, when the content of the first smoking material 21 is 100% by mass and the density of the filling 23 is less than 295 mg / cm3 (in this case, since the content of the first smoking material 21 is 100% by mass, the density of the filling 23 is equal to the density of the first smoking material 21), because the density of the first smoking material 21 is low, the first gap 51 and the second gap 52 become large, and there is a high possibility that the first smoking material 21 will fall off from the filling 23. When the heating element 20 is turned downward and the smoking device cartridge 1 is held, the first smoking material 21 may fall. Furthermore, since the filling amount of the first smoking material 21 is extremely small, it is inferior in terms of aroma and taste.

[0030] On the other hand, when the content of the first smoking material 21 is 100% by mass and the density of the filling 23 exceeds 675 mg / cm3, because the density of the first smoking material 21 is high, the first gap 51 and the second gap 52 become small, and there is a possibility that the fluidity of the airflow in the heating element 20 will not be good. Also, there is a possibility that it will be difficult to insert the heating part 75 (see FIG. 6) into the heating element 20.

[0031] If, when the filling 23 contains only the first smoking material 21, the reason for the density of the filling 23 being less than 295 mg / cm3 is that the thickness or width of the first smoking material 21 is large. When the first smoking material 21 with a large thickness and width is filled into the heating element 20, if the long sides are in contact with each other, the gap will not become large, but if there are many cases where the long side and the short side are in contact with each other, a large gap will be formed and the density cannot be increased. Therefore, in order to make the density of the filling 23 higher than 295 mg / cm3, it can be solved by making the thickness of the first smoking material 21 thinner or the width narrower, but making the thickness thinner or the width narrower has a problem that it is not easy to process in terms of manufacturing.

[0032] Also, even if the process of making the thickness of the first smoking material 21 thinner and the width narrower can be realized, when filling the first smoking material 21, there is a possibility that the first smoking materials will adhere to each other with almost no gap. In this case, a problem occurs that the density of the filling 23 becomes too high.

[0033] Therefore, in the present embodiment, without changing the shape of the first smoking material 21 from the conventional one, in order to set the packing density to an appropriate value, means is adopted to allow a second smoking material 22 different from the first smoking material 21 to enter the first gap 51 or the second gap 52.

[0034] When the content of the first smoking material 21 is small and the content of the second smoking material 22 is large, the first smoking material 21 may fall off from the filler 23. In particular, when the first smoking material 21 is less than 50% by mass, the possibility tends to increase.

[0035] On the other hand, when the content of the first smoking material 21 is large and the content of the second smoking material 22 is small, the second smoking material 22 cannot sufficiently fill the first gap 51 and the second gap 52, and the second smoking material 22 may fall off from the filler 23. In addition, since the content of the second smoking material 22 is significantly reduced, it is inferior in terms of aroma and taste. In particular, when the first smoking material 21 (filler) is greater than 95% by mass, the possibility tends to increase.

[0036] Therefore, in the present embodiment, comprehensively judging from the viewpoint of preventing the first smoking material 21 from falling off and in terms of aroma and taste, the content of the first smoking material 21 in the filler 23 is in the range of 50 to 95% by mass. More preferably, when the content of the first smoking material 21 is in the range of 65 to 75% by mass, not only can the prevention of falling off be achieved, but also the content of the second smoking material 22 can be increased, so that the aroma and taste can be significantly improved.

[0037] Next, specific examples of the raw materials used as the filler 23 (the first smoking material 21, the second smoking material 22) will be described. The first smoking material 21 and the second smoking material 22 are each composed of any one or a combination of a plurality of the following raw materials. However, in the present embodiment, in order to improve the aroma and taste, the first smoking material 21 and the second smoking material 22 are configured such that at least a part of the raw materials are different from each other.

[0038] The filler 23 is made from tobacco plants or non-tobacco plants. Examples of tobacco plants include tobacco leaves, tobacco stems, expanded tobacco, homogenized tobacco, etc. Non-tobacco plants refer to plants other than tobacco plants. Preferred parts of non-tobacco plants include leaves, pulp, seeds, roots (such as bulbous roots and tuberous roots), stems, tubers, barks (such as stem barks and tree barks), flowers (such as petals, stamens, pistils, etc.), trunks, branches, etc.

[0039] In addition, the "plant" referred to in this specification means a group relative to animals, and includes not only organisms such as grasses and trees that have roots and are fixed in place and alive, but also algae such as microalgae and seaweeds, and fungi such as mushrooms.

[0040] The filler 23 is, for example, appropriately mixed with an aerosol former that generates an aerosol, microcrystalline cellulose, an additive for adding flavor, a preservative, a binder or a thickener, etc. to dried and pulverized non-tobacco plants, pulverized or classified into a powdery or granular form, or formed into a sheet form, and then cut to have a predetermined width and length to be in a strip shape or a rod shape.

[0041] For example, when the part of the non-tobacco plant is a leaf, preferably tea can be used. Teas not only differ in the plants that become tea, but also become different teas depending on the processing method even for the same plant. Specifically, for example, Japanese tea, black tea, ashitaba tea, sweet tea, amacha tsuru tea, aloe tea, ginkgo leaf tea, oolong tea, turmeric tea, white mustard tea, ezoukoghi tea, big leaf tobacco tea, kaki oshidashi tea, persimmon leaf tea, chamomile tea, camomile tea, kawaragemme tea, quince tea, chrysanthemum tea, gymnema tea, guava tea, kukicha tea, yawata leaf tea, black soybean tea, gennoshokou tea, brown rice tea, burdock tea, comfrey tea, hibiscus tea, cherry tea, saffron tea, shiitake tea, perilla tea, jasmine tea, ginger tea, mugwort tea, seishou tea, senburi tea, buckwheat tea, tara no ki tea, dandelion tea, sweet tea, dokudami tea, eucommia tea, nata mame tea, niwatoko tea, nezumi mochi tea, adzuki tea, habu tea, loquat leaf tea, pu-erh tea, red flower tea, pine needle tea, mate tea, barley tea, megusurinoki tea, mugwort tea, eucalyptus tea, monk fruit tea, rooibos tea, bitter melon tea, etc. can be mentioned. For these teas, the tea leaves after drinking can also be used. By using tea leaves or the like, expensive teas and the like can be reused and effectively utilized.

[0042] Furthermore, extracts of the non-tobacco plants exemplified above, so-called extracts and processed products can also be used. Examples of the form of the extract include liquid, water candy-like, powder, granule, solution, etc.

[0043] Aerosol formers as raw materials for the filler 23 include glycerin, propylene glycol, sorbitol, triethylene glycol, lactic acid, diacetin (glycerin diacetate), triacetin (glycerin triacetate), triethylene glycol diacetate, triethyl citrate, isopropyl myristate, methyl stearate, dimethyl dodecanedioate, dimethyl tetradecanedioate, etc. Among them, glycerin and propylene glycol are preferred.

[0044] Microcrystalline cellulose as a raw material for the filler 23 is obtained, for example, by partially depolymerizing α-cellulose obtained from the pulp of fibrous plants with an acid, removing the soluble portion from the cellulose, and appropriately crystallizing the insoluble portion.

[0045] The microcrystalline cellulose may remain in powder form or may be dispersed in a solvent such as water to form a suspension. In this case, a high-speed stirrer or a high-pressure homogenizer can be used for dispersion in the solvent.

[0046] Furthermore, a flavor additive for adding flavor as a raw material for the filler 23 is preferably used as needed. Examples of the flavor additive include peppermint, cocoa, coffee, extracts of black tea, and powders of catechins in tea extracts. As preservatives, those used in foods are preferred, and examples include sorbic acid, potassium sorbate, benzoic acid, and sodium benzoate.

[0047] The filler 23 (particularly the second smoking material 22) may contain menthol and a water-insoluble crosslinked polymer (preferably polyvinyl polypyrrolidone). By combining menthol with a water-insoluble crosslinked polymer, sublimation of menthol can be effectively suppressed, and the flavor of menthol can be maintained for a long period. Here, menthol is not limited to those obtained from natural products and may be a synthetic product. Also, those containing peppermint, mint, peppermint oil, and other menthols may be used.

[0048] The flavor additive is provided in the mouthpiece 40, for example, by impregnating the wall portion of the mouthpiece 40. The manner in which the flavor additive is provided in the mouthpiece 40 is not limited to such a manner. For example, the flavor additive may be provided in the mouthpiece 40 by embedding a capsule containing the flavor additive in the wall portion of the mouthpiece 40. Alternatively, the flavor additive may be arranged between the mouthpiece 40 and the heated body 20. When the flavor additive is encapsulated, the smoker can break the capsule by pressing it with a finger, and the aromatic component of the flavor additive can be volatilized at a desired timing.

[0049] Furthermore, when the flavor additive is encapsulated in microcapsules, for example, the encapsulated microcapsules may be provided on the heated body 20.

[0050] Examples of the binder or thickener as the raw material of the filler 23 include gums such as guar gum, xanthan gum, gum arabic, and locust bean gum, cellulose binders such as hydroxypropyl cellulose, carboxymethyl cellulose, hydroxyethyl cellulose, methyl cellulose, and ethyl cellulose, organic acids such as starch and alginic acid, and polysaccharides such as conjugate base salts of organic acids such as sodium alginate, sodium carboxymethyl cellulose, carrageenan, agar, and pectin, and combinations thereof.

[0051] (Method for manufacturing the filler) The manufacturing method of the aforementioned filler 23 will be described separately for each step. The manufacturing process of the filler 23 includes a drying and pulverizing step of drying and pulverizing the tobacco plant or non-tobacco plant as the main raw material and performing weighing, etc., a preparation step of performing pretreatment, weighing, etc. of other raw materials, a mixing step of mixing the raw materials to form a composition, and a filler forming step of forming the composition into a filler.

[0052] In the drying and pulverizing process, the tobacco plant or the part of the non-tobacco plant used as the main raw material (for example, leaves, seeds, dried fruits, stems, barks, roots, etc.) is processed into a predetermined pulverized product to form a composition. At this time, it is preferable to adjust the moisture content to a convenient amount 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 setting the temperature within this range, it is easy to reach the desired moisture content while avoiding the dissipation of the required flavor components. Furthermore, a sieving process for sieving the pulverized product can be provided in the drying and pulverizing process, and it can be adjusted to the desired particle size and then fed into the mixing process.

[0053] In the preparation process, the raw materials necessary for producing the filler 23 can be prepared. The aforementioned microcrystalline cellulose is weighed in the preparation process and fed into the mixing process.

[0054] In the mixing process, an ordinary 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.

[0055] In the filler forming process, the 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 filler 23 (the first smoking material 21). In this embodiment, in order to form a thin sheet, a three-roll mill is prepared. When using a three-roll mill, it is possible to form a sheet of a desired thickness with a doctor blade while performing kneading, dispersion, etc. by compression due to being pushed into the narrow space between the rolls and shearing due to the roll speed difference, which is preferable. It can also be produced using a press roller or a press machine.

[0056] In addition, to obtain the powdery or granular filler 23 (the second smoking material 22), it is preferable to appropriately pulverize or classify the above composition. The average particle size of the powdery or granular filler 23 is preferably, for example, 0.1 to 3.0 mm, more preferably 0.5 mm or less. The average particle size is determined, for example, by the sieving method described in JIS K 0069:1992. That is, this average particle size refers to the diameter corresponding to 50% of the mass obtained by integrating the masses from the sieve with the larger mesh size for the test results using a plurality of sieves. Also, the particle size at the 50% cumulative value in the particle size distribution determined by the laser diffraction / scattering method may be used as the average particle size.

[0057] In the filler forming step, other means such as passing the composition through an orifice under pressure for forming may be used. In the filler forming step, if necessary, flavor additives such as non-tobacco plants, aerosol formers, binders or thickeners, and preservatives may be further added, or water or the like may be added.

[0058] The thickness of the sheet obtained in the filler forming step is preferably in the range of 0.1 mm to 1.0 mm, more preferably in the range of 0.1 mm to 0.5 mm. The obtained sheet is cut to a predetermined width by a cutter, a rotary cutter of a rotary blade type, or the like.

[0059] Here, when the filler 23 is the first smoking material 21 formed in a strip shape or a rod shape and adhesiveness is imparted to its surface, there is no particular limitation as long as it is a means capable of imparting adhesiveness, but at least a part of the above-described binder may be adhered. By imparting adhesiveness, the powdery or granular filler 23 can be stably held and its function can be maintained well.

[0060] (Method for manufacturing a heating element) Next, a method for manufacturing the heating element 20 by winding the filler 23 produced by the above steps with the packaging member 25 will be described. FIGS. 5A to 5C are diagrams showing the manufacturing process of the heating element 20.

[0061] As shown in FIG. 5A, the packaging member 25 is placed on the opening / closing portion 61 of the pedestal 60, and a predetermined amount of filling material 23 (the first smoking material 21 and the second smoking material 22) is placed on the packaging member 25. For example, about 50 pieces of the first smoking material 21 are placed. At this time, the second smoking material 22 is dispersed and placed on the packaging member 25 so that the second smoking material 22 enters the first gap 51. Note that the pair of opening / closing portions 61 provided on the pedestal 60 are configured to be movable in a direction away from each other.

[0062] Next, as shown in FIG. 5B, the pair of opening / closing portions 61 are moved in a direction away from each other to form a recess 62 into which the packaging member 25 drops, and the filling material 23 is wrapped with the packaging member 25 that has dropped into the recess 62. Then, as shown in FIG. 5C, both ends of the packaging member 25 are adhered to fill the filling material 23 inside the packaging member 25. Thus, the heated body 20 is completed.

[0063] (Method of using a cartridge for a smoking device) A method of using the cartridge 1 for a smoking device will be described. FIG. 6 is a cross-sectional view of the state where the cartridge 1 for a smoking device is inserted into the smoking device 70. The cartridge 1 for a smoking device is used by being attached to a heating type smoking device 70. The smoking device 70 has an insertion portion 72 for inserting the cartridge 1 for a smoking device. A needle-shaped or blade-shaped heating portion 75 is provided in the insertion portion 72. When the heating portion 75 generates heat in a state where the cartridge 1 for a smoking device is inserted into the insertion portion 72, an aerosol is generated from the filling material 23. When a smoker holds the mouthpiece 40 and sucks in this state, the aerosol flows in the order of the flow path 35, the transfer member 39, and the mouthpiece 40 and flows into the smoker's mouth.

[0064] According to the cartridge 1 for a smoking device according to the first embodiment configured as described above, the following effects can be obtained.

[0065] By arranging the second smoking material 22 in the first gap 51 formed between the first smoking materials 21 and the second gap 52 formed between the first smoking material 21 and the packaging member 25, the filling 23 includes the first smoking material 21 and the second smoking material 22, so that the aroma and taste are improved. That is, since the second smoking material 22 is filled in the portion that was previously a gap, the content of the smoking material in the filling 23 can be increased and the density can be increased compared to the prior art. As a result, the aroma and taste are improved compared to the prior art.

[0066] Further, the first smoking material 21 is formed of a strip-shaped or rod-shaped member, the second smoking material 22 is formed of a powdery or granular member, and the average particle diameter of the second smoking material 22 is equal to or less than the long side of the rectangular cross-section of the first smoking material 21. Therefore, the second smoking material 22 can easily enter the gaps 51 and 52. As a result, when the filling 23 is wound with the packaging member 25, no special process is required to arrange the second smoking material 22 in the gaps 51 and 52. That is, according to the first embodiment, by simply preparing the first smoking material 21 and the second smoking material 22 in advance, the smoking implement cartridge 1 that can easily improve the direction and taste without changing the conventional manufacturing process can be provided.

[0067] In addition, since the content of the first smoking material 21 is in the range of 50 to 95% by mass (preferably 65 to 75% by mass) and the density of the first smoking material 21 is in the range of 295 to 675 mg / cm3 (preferably 500 to 675 mg / cm3), it is possible to prevent the first smoking material 21 from falling off the heating element 20. As a result, both ends of the heating element 20 can be handled even with the first smoking material 21 exposed. That is, there is no need to provide a lid member that covers both ends of the heating element 20. Therefore, cost reduction of the smoking implement cartridge 1 can be achieved.

[0068] In addition, since the surface of the first smoking material 21 has adhesiveness, there is little concern that the second smoking material 22 will separate from the first smoking material 21 and fall off the heating element 20.

[0069] In addition, since at least part of the raw materials of the first smoking material 21 and the second smoking material 22 are different from each other, the aroma and taste are further improved. Also, even if a common raw material is used for the first smoking material 21 and the second smoking material 22, by simply changing at least part of the raw material of the second smoking material 22, an aroma and taste according to the preference of the smoker can be realized, so that the variations of the cartridge for a smoking device can be easily increased.

[0070] (Second Embodiment) Next, the cartridge for a smoking device according to the second embodiment will be described. The cartridge for a smoking device according to the second embodiment has basically the same configuration as the cartridge 1 for a smoking device according to the first embodiment, but the internal configuration of the filling 23 is different. Specifically, the shape of the smoking material is different. Therefore, in the following description, the description will focus on this difference, and the description overlapping with the first embodiment will be omitted.

[0071] In the second embodiment, the filling 23 includes a strip-shaped smoking material 121 and a rod-shaped smoking material 122. FIG. 7 is a view showing the outer shape of the strip-shaped smoking material 121, and FIG. 8 is a view showing the outer shape of the rod-shaped smoking material 122.

[0072] As shown in FIG. 7, the strip-shaped smoking material 121 is composed of a strip-shaped member having a cross-section orthogonal to the central axis C3 formed in a substantially rectangular shape (rectangular shape). The ratio of the long side a1 to the short side b1 is, for example, in the range of 1.5:1 to 30:1, and the length c1 is substantially the same as the length of the heating body 20. As an example of the dimensions of the strip-shaped smoking material 121, the long side a1 is 1.5 mm, the short side b1 is 0.3 mm, and the length c1 is 12 mm. And an adhesive or the like is attached to the surface of the strip-shaped smoking material 121.

[0073] On the one hand, as shown in FIG. 8, the rod-shaped smoking material 122 is composed of a rod-shaped member having a substantially square (rectangular) cross-section perpendicular to the central axis C4. The ratio of the long side a2 to the short side b2 is, for example, in the range of 1:1 to 1.5:1, and the length c2 is substantially the same as the length of the heating element 20. As an example of the dimensions of the rod-shaped smoking material 122, the long side a2 is 0.6 mm, the short side b2 is 0.4 mm, and the length c2 is 12 mm. Therefore, in the present embodiment, the cross-sectional area (first cross-sectional area) of the strip-shaped smoking material 121 is larger than the cross-sectional area (second cross-sectional area) of the rod-shaped smoking material 122. Note that the cross-sectional shape of the rod-shaped smoking material 122 may be circular. That is, the rod-shaped smoking material 122 may be either a square rod-shaped member or a round rod-shaped member.

[0074] FIG. 9 is a cross-sectional view of the smoking device cartridge according to the second embodiment taken along the line IV-IV shown in FIG. 1. As shown in FIG. 9, the rod-shaped smoking material 122 is disposed in a third gap 151 formed between the strip-shaped smoking materials 121 and the strip-shaped smoking materials 121. Further, the rod-shaped smoking material 122 is also disposed in a fourth gap 152 formed between the packaging member 25 and the strip-shaped smoking material 121. That is, in the present embodiment, the interior of the packaging member 25 is filled with a large number of strip-shaped smoking materials 121, and the third gap 151 and the fourth gap 152 are filled with a large number of rod-shaped smoking materials 122.

[0075] Here, in the present embodiment, the content of the strip-shaped smoking material 121 in the filler 23 is 50 to 95% by mass, preferably 65 to 75% by mass. And the density of the filler 23 is 295 to 675 mg / cm3, preferably 500 to 675 mg / cm3. The reason for this numerical range is the same as that of the first embodiment described above.

[0076] According to the cigarette cartridge for a smoking device according to the second embodiment configured as described above, the same effects as those of the first embodiment described above can be achieved. Further, according to the second embodiment, the rod-shaped smoking material 122 fits into the third gap 151 and the fourth gap 152, and the density of the filler 23 increases, so that the strip-shaped smoking material 121 and the rod-shaped smoking material 122 can be prevented from falling off the filler 23, achieving a remarkable effect.

[0077] Note that the present invention is not limited to the above 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 embodiments show preferred examples, but those skilled in the art can realize various alternative examples, modification examples, variation examples, or improvement examples from the content disclosed in this specification, and these are included in the technical scope described in the appended claims.

[0078] In addition to those exemplified above, various raw materials can be used for the raw materials of the first smoking material 21, the second smoking material 22, the strip-shaped smoking material 121, and the rod-shaped smoking material 122. For example, the raw materials disclosed in Patent Document 1 (Japanese Patent No. 6516907) can also be applied to the present invention.

[0079] The shape of the strip-shaped or rod-shaped filler 23 (first smoking material 21) may be, for example, in the form of strands, porous, etc. To make it porous, for example, it can be formed by piercing a dried sheet with a plurality of needles several times (other methods are also acceptable).

[0080] The shape of the powdery or granular filler 23 (second smoking material 22) may be, for example, in the form of granules, pellets, etc.

[0081] The powdery or granular filler 23 (second smoking material 22) may be solidified into a block shape, or may be made into a paste shape by adding a little water or oil.
