BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a sectional view of a smoking article cartridge 1 according to a first embodiment of the present invention. As shown in FIG. 1 , the smoking implement cartridge 1 according to the first embodiment includes a heated body 20 , a support member 30 , and a mouthpiece 40 . The object to be heated 20, the support member 30, and the mouthpiece 40 are arranged side by side on the central axis C1. The body to be heated 20 , the support member 30 and the mouthpiece 40 are wound and integrated with the sheet-shaped exterior member 10 . The exterior member 10 is made of paper, for example.

Here, the smoking implement cartridge 1 shown in FIG. 1 is formed to have a diameter of 6.5 to 7.5 mm and a length of 40 to 60 mm, for example. Moreover, the object to be heated 20 has a length of 10 to 25 mm. Of course, the smoking implement cartridge 1 may be formed in other dimensions.

The body to be heated 20 is a cylinder extending from one end facing the supporting member 30 inside the exterior member 10 to the other end being inserted into a heating type smoking article 70 described later. It is arranged in a space of a shape. The "outer diameter of the object to be heated" in the present invention is defined as the outer diameter of this cylindrical space. In this embodiment, the object to be heated 20 (aerosol-forming base material 23) is directly covered with the exterior member 10 (see FIG. 1), and the outer diameter D of the object to be heated 20 is the diameter of this cylindrical space. The outer diameter is equal to the inner diameter of the exterior member 10 . The outer diameter D has a substantially constant value along the central axis C1.

The heated body 20 includes an aerosol-forming substrate 23 that generates an aerosol when heated. Note that the heated body 20 includes any form of aerosol-forming substrate 23 . Examples of the form of the aerosol-forming substrate 23 include a form in which members such as strips, rods, and granules, which will be described later, are filled at a high density or at a low density, and a plurality of members such as strips, rods, and granules. and a form consisting of a plurality of capsules containing a flavor additive. Of course, the forms of the aerosol-forming substrate 23 which are not listed above and are described below are also possible.

Note that even if the filling state of the aerosol-forming substrate 23 contained in the heated body 20 changes inside the exterior member 10 according to the orientation of the smoking device cartridge 1, the outer diameter D of the heated body 20 does not change. The size is always constant, and in the case of this embodiment, it is equal to the size of the inner diameter of the exterior member 10 as described above.

In the above description, the case where the object to be heated 20 (the aerosol forming substrate 23) is directly covered with the exterior member 10 has been described. In the case of a structure wound by a member, the size of the outer diameter D of the heated body 20 is equal to the size of the outer diameter of the packaging member. For example, when the strip-shaped, rod-shaped, or granular aerosol-forming substrates 23 described above are filled in the packaging member at a low density, the aerosol-forming substrates 23 may move inside the packaging member. Since the shape of the packaging member itself is unchanged, the outer diameter D of the heated body 20 is also unchanged.

Further, the supporting member 30 is the “supporting member” of the present invention as long as it has the function of preventing the movement of the heated body 20 regardless of the packing density of the aerosol-forming substrate 23 constituting the heated body 20 . include. In other words, the technical scope of the present invention includes the configurations of the heated body 20 and the supporting member 30 in any manner described above. For example, when the object to be heated 20 is filled with the aerosol-forming substrate 23 made of a strip-shaped, rod-shaped, granular or granular member at a low density, the smoker may heat the smoking implement 70 in the shape of a needle or a blade. By inserting the portion 75 into the aerosol-forming substrate 23, even if the aerosol-forming substrate 23 is pushed toward the supporting member 30, the supporting member 30 prevents the aerosol-forming substrate 23 from moving toward the supporting member 30. can.

The aerosol-forming substrate 23 is wound around the exterior member 10 to form a cylindrical shape. The outer diameter D of the aerosol-forming substrate 23 is equal to the outer diameter D of the heated body 20, and has a substantially constant value along the central axis C1. The size of this outer diameter D is, for example, preferably in the range of 4.0 mm to 7.5 mm, more preferably in the range of 5.0 mm to 7.0 mm. If the size of the outer diameter D is set to 4.0 mm or more, the minimum required amount of aerosol can be generated. Also, if the outer diameter D is set to 5.0 mm or more, a sufficient amount of aerosol can be generated. Furthermore, if the size of the outer diameter D is set to 7.5 mm or less, the heated body 20 can be attached to the smoking article 70 . Moreover, if the size of the outer diameter D is set to 7.0 mm or less, the heated body 20 can be easily attached to the smoking article 70 .

Both ends of the aerosol-forming substrate 23 are exposed without being covered with a cover member (for example, paper). One end 23 a of the two ends of the aerosol-forming substrate 23 faces the support member 30 , and the other end 23 b is the side inserted into the insertion portion 72 of the smoking article 70 . Here, the term "end portion" as used in this specification includes an end face and a portion within a predetermined range from the end face along the central axis C1. The object to be heated 20 may have a structure in which the aerosol-forming base material 23 is wrapped with a sheet-like wrapping member made of paper, for example, or may have a structure in which the aerosol-forming base material 23 is covered with a lid member.

The aerosol-forming substrate 23 is composed of a smoking material 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, configured by bundling strip-shaped members, and is arranged such that its axial direction (longitudinal direction) is along the central axis C1.

When the aerosol-forming substrate 23 is composed of a strip-shaped member, the cross section orthogonal to the central axis C1 is substantially rectangular, and the ratio of the long side to the short side of the cross section is, for example, 1:1 to 30:1. A range is preferred. The length of the long side is preferably in the range of 0.1 mm to 7.5 mm, more preferably in the range of 0.1 mm to 3.0 mm. The length of the short side 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. Also, the length of the aerosol-forming base material 23 is preferably substantially the same as the length of the object to be heated 20 . The length of the aerosol-forming substrate is preferably in the range of 10 mm to 25 mm, more preferably in the range of 10 mm to 20 mm. An example of the dimensions of such an aerosol-forming substrate 23 is 1.5 mm long side, 0.3 mm short side, and 12 mm long.

Of course, the aerosol-forming substrate 23 is not limited to strip-shaped members. For example, it may be a rod-shaped member, or a powder-like or paste-like member. The aerosol-forming base material 23 is a combination of a strip-shaped member and a powder-like member, a combination of a strip-shaped member and a rod-shaped member, a combination of a rod-shaped member and a powder-shaped member, or a combination of a strip-shaped member. A structure comprising a combination of a rod-like member and a powder-like member may also be used. In these cases, it is preferable to use different materials for at least a part of each member, because this improves the aroma and taste.

The mouthpiece 40 is a part that constitutes the mouthpiece of the smoking device cartridge 1, and is made of paper or the like, for example. Also, the mouthpiece 40 is formed to have a diameter of 6.5 mm to 7.5 mm and a length of 50 mm or less along the central axis C1, for example. Furthermore, the mouthpiece 40 may be formed into a cylindrical shape by winding a sheet-like member made of paper, for example, or may include a cellulose acetate filter or the like for removing fine particles. Part of the fine particles in the water vapor and aerosol generated by the heated body 20 is filtered by the filter of the mouthpiece 40 .

The support member 30 is formed in a cylindrical shape by winding a sheet member 31 made of paper, for example, once or multiple times. The support member 30 is arranged between the aerosol-forming substrate 23 and the mouthpiece 40 so that its axial direction is along the central axis C1. The support member 30 is formed, for example, to have a length of 50 mm or less along the central axis C1. A first end 30a, which is one of the ends of the support member 30, faces one end 23a of the aerosol-forming substrate 23, and a second end 30b, which is the other end. is the side opposite to the first end 30 a , that is, the side facing the mouthpiece 40 . A first end 30 a of the support member 30 abuts the aerosol-forming substrate 23 and a second end 30 b abuts the mouthpiece 40 . Then, the aerosol passes through the inside of the support member 30 .

The support member 30 has a truncated cone-shaped through hole 31a through which the aerosol passes, and the shape of the first end 30a and the shape of the second end 30b are different. Specifically, by winding the sheet member 31 constituting the support member 30 so that the diameter of the second end portion 30b is smaller than that of the first end portion 30a, the inner diameter r1 of the first end portion 30a is increased. is larger than the inner diameter r2 of the second end 30b. Also, the inner diameter of the support member 30 gradually decreases from the first end portion 30a toward the second end portion 30b. Further, the outer diameter R1 of the first end portion 30a of the support member 30 is larger than the outer diameter R2 of the second end portion 30b.

The size of the inner diameter r1 of the support member 30 is, for example, preferably in the range of 0.5 mm to 6.5 mm, more preferably in the range of 1.0 mm to 5.0 mm. If the size of the inner diameter r1 is set to 0.5 mm or more, it is possible to ensure the minimum required size of the flow path for the aerosol to flow through the through hole 31a of the support member 30. FIG. Also, if the size of the inner diameter r1 is set to 1.0 mm or more, it is possible to ensure a sufficient size of the flow path for the aerosol to flow through the through hole 31a of the support member 30. FIG. Furthermore, if the size of the inner diameter r1 is set to 6.5 mm or less, the minimum thickness of the support member 30 required to support the object to be heated 20 can be ensured. Further, if the size of the inner diameter r1 is set to 5.0 mm or less, the thickness of the supporting member 30 sufficient to support the object to be heated 20 can be ensured.

Also, the size of the inner diameter r2 of the support member 30 is preferably in the range of 0.5 mm to 6.5 mm, more preferably in the range of 0.5 mm to 4.5 mm. By setting the size of the inner diameter r2 to 0.5 mm or more, it becomes possible to ensure the minimum required size of the flow path for the aerosol to flow through the through hole 31a of the support member 30. FIG. Furthermore, if the size of the inner diameter r2 is set to 6.5 mm or less, the minimum thickness of the support member 30 required to support the object to be heated 20 can be ensured. Further, if the size of the inner diameter r2 is set to 4.5 mm or less, the thickness of the support member 30 sufficient to support the object to be heated 20 can be ensured.

When manufacturing the support member 30, by appropriately selecting the sizes of the inner diameters r1 and r2 within the above ranges, the size of the flow channel of the support member 30 is adjusted to transfer the aerosol to the mouthpiece 40. can be ensured. In addition, by adjusting the support strength of the heated body 20 (aerosol-forming base material 23 ) by the support member 30 , the heated body 20 can be appropriately supported according to the material of the aerosol-forming base material 23 .

In addition, by appropriately selecting the length along the central axis C1 of the support member 30 and the inner diameters r1 and r2 according to the form of the aerosol-forming substrate 23 within the above ranges, the inclination of the outer peripheral portion of the support member 30 can be reduced. The angle can be adjusted to prevent the aerosol-forming substrate 23 from moving toward the mouthpiece 40 . For example, when the aerosol-forming substrate 23 is powdery, granular, or granular (for example, a capsule), the length of the support member 30 is set short and the size of the inner diameter r1 is set sufficiently larger than the size of the inner diameter r2. Then, the inclination angle of the outer peripheral portion of the support member 30 with respect to the first end portion 30a can be set small. At this time, the outer peripheral portion of the support member 30 is inclined downward from the first end portion 30a toward the second end portion 30b. In this way, even if the aerosol-forming substrate 23 enters the through hole 31a of the support member 30, the aerosol-forming substrate 23 contacts the outer peripheral portion of the support member 30 and cannot move toward the mouthpiece 40. . Therefore, movement of the aerosol-forming substrate 23 toward the mouthpiece 40 can be prevented within the through hole 31 a of the support member 30 . Note that if the inner diameter r1 of the support member 30 is made small so that the aerosol-forming substrate 23 can be sufficiently supported by the thickness portion between the inner diameter r1 and the outer diameter R1 of the support member 30, then regardless of the inner diameter r2 , it becomes difficult for the aerosol-forming substrate 23 to enter the through hole 31 a of the support member 30 .

The size of the outer diameter R1 of the support member 30 is, for example, preferably in the range of 4.0 mm to 7.5 mm, more preferably in the range of 5.0 mm to 7.0 mm. Further, the size of the outer diameter R2 of the support member 30 is preferably in the range of 1.0 mm to 7.5 mm, more preferably in the range of 1.5 mm to 6.5 mm. It is preferable to set the size of the outer diameter R1 to be equal to the size of the outer diameter D of the aerosol-forming substrate 23 . That is, it is preferable that the dimension of the outer diameter R1 and the dimension of the outer diameter D are the same. This prevents the aerosol-forming substrate 23 from moving toward the support member 30 through between the first end 30 a of the support member 30 and the exterior member 10 .

Next, the relationship between the outer diameter R1 and inner diameter r1 of the support member 30 and the outer diameter D of the aerosol-forming substrate 23 will be described with reference to FIG. The drawing on the left side of FIG. 2 is a vertical section of the aerosol-forming substrate 23 taken along the line II-II of the smoking device cartridge 1 shown in FIG. 1 and viewed from the support member 30 side. The drawing on the right side is a longitudinal section of the support member 30 viewed from the aerosol-forming substrate 23 side.

2, L1 is a straight line passing through the aerosol-forming base material 23 and the top of the support member 30, L2 is a straight line passing through the top of the inner peripheral portion of the support member 30 (sheet-like member 31), and L3 is the straight line passing through the top of the support member 30. A straight line passing through the bottom of the inner circumferential portion, L4, is a straight line passing through the aerosol-forming substrate 23 and the bottom of the support member 30 .

The outer diameter R<b>1 of the support member 30 is set equal to the outer diameter D of the aerosol-forming substrate 23 . As shown in FIG. 2, the outer diameter R1 of the support member 30 and the outer diameter D of the aerosol-forming substrate 23 both correspond to the length between L1 and L4. Therefore, the first end 30 a of the support member 30 can support the outer peripheral portion of the one end 23 a of the aerosol-forming substrate 23 . Note that the outer diameter R1 may be smaller than the outer diameter D as long as the first end portion 30a of the support member 30 can support the outer peripheral portion of the aerosol-forming substrate 23 .

In addition, the inner diameter r1 of the support member 30 corresponds to the length between L2 and L3 and is smaller than the outer diameter D of the aerosol-forming substrate 23 . Specifically, the inner diameter r1 of the support member 30 is the length (Δr) between the outer diameter R1 (≦the outer diameter D) of the support member 30 and the length between L1 and L2 and the length between L3 and L4 ( Δr), that is, the length excluding the thickness (2Δr) of the support member 30 (sheet-like member 31). Therefore, the first end portion 30a of the support member 30 can be supported by the thickness of the sheet-like member 31 from the outer peripheral portion of the aerosol-forming substrate 23 to the inner portion of the predetermined range.

The magnitude of Δr described above is, for example, preferably in the range of 0.5 mm to 3.5 mm, more preferably in the range of 1.0 mm to 3.25 mm. By setting the magnitude of Δr to 0.5 mm or more, it is possible to secure the minimum thickness of the supporting member 30 necessary for supporting the object to be heated 20 . Also, if the magnitude of Δr is set to 1.0 mm or more, it is possible to ensure the thickness of the support member 30 sufficient to support the object to be heated 20 . Furthermore, setting the size of Δr to 3.5 mm or less makes it possible to ensure the minimum required size of the flow path for the aerosol to flow through the through hole 31 a of the support member 30 . Also, if the size of Δr is set to 3.25 mm or less, it is possible to ensure a sufficient size of the flow path for the aerosol to flow through the through hole 31 a of the support member 30 .

As described above, the outer diameter R1 and inner diameter r1 of the support member 30 have the relationship as described above with respect to the outer diameter D of the aerosol-forming substrate 23, so that the support member 30 can be used only at the outer peripheral portion of the aerosol-forming substrate 23. Instead, the support can be provided from the outer peripheral portion to the inner portion of the predetermined range.

Although the inner diameter r1 of the support member 30 is larger than the inner diameter r2 in FIG. 1, the configuration is not limited to this. If the one end 23a of the aerosol-forming substrate 23 can be supported by the thickness of the support member 30 (the sheet member 31), the inner diameter r2 of the support member 30 can be equal to or larger than the inner diameter r1. good. If the inner diameter r2 of the support member 30 is equal to the inner diameter r1, the inner diameter of the support member 30 may be uniform from the first end 30a to the second end 30b. Further, when the inner diameter r2 of the support member 30 is larger than the inner diameter r1, the inner diameter of the support member may increase from the first end 30a toward the second end 30b, or may increase from the first end 30a. It may gradually increase toward the second end 30b. Furthermore, the outer diameter R1 and the outer diameter R2 of the support member 30 may be the same regardless of whether the inner diameter r2 of the support member 30 is equal to the inner diameter r1 or larger than the inner diameter r1.

The support member 30 may be configured such that the through holes 31a thereof are filled with various fillers. Such fillers include, for example, particulate matter, fibrous matter, porous matter, flavor additives, and the like.

In the case of particulate filling, plastic particles, for example, can be employed. The shape of the granules is not particularly limited, and for example, the cross-sectional shape may be circular, elliptical, or polygonal. Further, the granules may be solid or hollow, and preferably have a particle size of, for example, 0.5 mm to 1 mm.

When a fibrous material is filled, polyester fibrous bodies such as cellulose acetate (CA) fibers and polyethylene terephthalate (PET) can be used.

When a porous material is filled, for example, polyolefin resin such as PE, PP, PET resin, CA resin, polylactic acid (PLA), metal foil such as aluminum, and metal itself can be used.

Furthermore, when the above-mentioned particulate matter is filled, as the filler, activated carbon that can remove specific chemical substances (such as tar) mixed in the aerosol, and particles made of inorganic materials such as ceramics and glass are adopted. Alternatively, a mixture of these plural types of particles may be employed. Also, a removing agent (eg, chitosan) capable of removing the chemical substances (eg, aldehydes such as formaldehyde) may be added to part or all of the packing.

Alternatively, when the above-described granular materials are filled, the filling may be plant-based raw materials such as coffee grounds after extracting coffee or used tea leaves after extracting tea leaves. Since these vegetable raw materials are porous and have a high deodorizing effect, the support member 30 with a deodorizing effect can be realized. When using coffee grounds, it is preferable to use the coffee grounds in the form of a dumpling with starch or the like because the particle size of the coffee grounds is small. In the case of using used tea leaves, if the aerosol-forming substrate 23 is made of used tea leaves, both the aerosol-forming substrate 23 and the support member 30 can be manufactured from the same material.

When flavor additives are filled, for example, mint, cocoa, coffee, black tea extract, catechin powder of tea extract, etc. can be employed. As modes for filling the flavor additive into the through-holes 31a of the support member 30, there are various modes described below.

For example, if the flavor additive is enclosed in a capsule, this capsule may be placed in through-hole 31a. In this way, the smoker can destroy the capsule by pressing the capsule with a finger, and volatilize the aromatic component of the flavor additive at a desired timing. Moreover, when this capsule has heat-meltability, it melts by being exposed to an aerosol, and the flavor additive can be released to the outside. Furthermore, when this capsule is a microcapsule, this microcapsule may be embedded in the inner peripheral surface of the support member 30 . Of course, microcapsules may be arranged in the through holes 31a. If the flavor additive is not encapsulated, for example, the inner peripheral surface of the support member 30 may be impregnated with the flavor additive.

Next, specific examples of 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 raw materials shown below.

The aerosol-forming substrate 23 is sourced from tobacco or non-tobacco plants. Tobacco plants include tobacco leaves, tobacco stems, expanded tobacco, homogenized tobacco, and the like. Non-tobacco plants include plants other than tobacco plants. Preferred parts of non-tobacco plants include leaves, pulp, seeds, roots (scales, tuberous roots, etc.), stems, tubers, skins (stem bark, bark, etc.), flowers (petals, stamens, pistils, etc.), trunks, branches. etc.

As used herein, the term "plant" means a group of animals, and in addition to organisms such as grasses and trees that live in a fixed location with roots, microalgae, seaweeds, etc. Also includes algae such as algae, fungi such as mushrooms, and the like.

The aerosol-forming substrate 23 is, for example, an aerosol former that generates an aerosol, a microcrystalline cellulose, an additive that adds flavor, a preservative, a binder, or a thickener, etc., to dried and pulverized non-tobacco plants. They are mixed, pulverized or classified into powder or granules, or formed into a paste. Also, the aerosol-forming base material 23 is formed into a sheet shape and then cut into strips or rods having a predetermined width and length.

For example, when the non-tobacco plant parts are leaves, teas can be preferably used. Not only are tea plants different, but even the same plant can be made into different teas depending on the processing method. Specifically, for example, Japanese tea, black tea, Angelica keiskei tea, sweet tea, Gynostemma tea, aloe tea, ginkgo biloba tea, oolong tea, turmeric tea, oak tea, eleuthero tea, plantain tea, persimmon tea, persimmon leaf tea, Chamomile tea, chamomile tea, Kawahara tea, quince tea, chrysanthemum tea, gymnema tea, guava tea, wolfberry tea, soft leaf tea, black soybean tea, gennoshoko tea, brown rice tea, burdock tea, comfrey tea, bifu tea , cherry blossom tea, saffron tea, shiitake mushroom tea, perilla tea, jasmine tea, ginger tea, horsetail tea, sekisho tea, assembly tea, buckwheat tea, taranogi tea, dandelion tea, sugar bean tea, dokudami tea, eucommia tea, soybean tea, elderberry tea , mouse wax tea, pigeon barley tea, habu tea, loquat leaf tea, pu-erh tea, safflower tea, pine needle tea, mate tea, barley tea, megusurinoki tea, mugwort tea, eucalyptus tea, luohan fruit tea, rooibos tea, bitter gourd tea and the like. For these teas, tea leaves after drinking may be used. Expensive tea can be reused and effectively utilized by using used tea leaves.

Furthermore, extracts of non-tobacco plants exemplified above, so-called extracts and processed products can also be used. The forms of the extract include liquid, starch syrup, powder, granules, solution and the like.

Aerosol formers as raw materials for the aerosol-forming substrate 23 include glycerin, propylene glycol, sorbitol, triethylene glycol, lactic acid, diacetin (glycerin diacetate), triacetin (glycerin triacetate), triethylene glycol diacetate, citric acid, triethyl acid, isopropyl myristate, methyl stearate, dimethyl dodecanedioate, dimethyl tetradecanedioate and the like. Among them, glycerin and propylene glycol are preferred.

Microcrystalline cellulose as a raw material for the aerosol-forming base material 23 is obtained, for example, by partially depolymerizing α-cellulose obtained from fibrous plant pulp with an acid, and a soluble portion is extracted from the cellulose. is removed and the insoluble portion is crystallized accordingly.

The microcrystalline cellulose may be used as a powder, or may be dispersed in a solvent such as water and used as a liquid suspension. In this case, a high-speed stirrer, a high-pressure homogenizer, or the like can be used for dispersion in the solvent.

Furthermore, a flavor additive for adding flavor is preferably used as a raw material for the aerosol-forming substrate 23 as necessary. Examples of flavor additives include mint, cocoa, coffee, black tea extract, catechin powder of tea extract, and the like. As the preservative, those used in foods are preferred, and examples thereof include sorbic acid, potassium sorbate, benzoic acid, sodium benzoate and the like.

The aerosol-forming substrate 23 may contain menthol and a water-insoluble crosslinked polymer (preferably polyvinylpolypyrrolidone). 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 of time. Here, menthol is not limited to those obtained from natural products, and may be synthetic products. Mint, mint, peppermint oil, and others containing menthol may also be used.

The flavor additive is applied to the mouthpiece 40 by, for example, impregnating the walls of the mouthpiece 40 . The aspect in which the flavor additive is provided in the mouthpiece 40 is not limited to this aspect. A flavor additive may be provided at 40 . Alternatively, a capsule containing a flavor additive may be placed 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 the capsule with a finger, and can volatilize the aromatic component of the flavor additive at a desired timing. Become.

Furthermore, when the flavor additive is encapsulated in microcapsules, for example, the encapsulated microcapsules may be provided on the heated body 20 . Of course, the microcapsules may be provided on the support member 30 as well.

Binders or thickeners as raw materials for the aerosol-forming substrate 23 include gums such as guar gum, xanthan gum, gum arabic and locust bean gum; Cellulose binders such as starch, organic acids such as alginic acid, polysaccharides such as sodium alginate, sodium carboxymethylcellulose, caranagin, conjugate base salts of organic acids such as agar and pectin, and combinations thereof.

(Method for producing aerosol-forming substrate)
The method for manufacturing the aerosol-forming base material 23 described above will be described in each step. The manufacturing process of the aerosol-forming base material 23 includes a drying/pulverizing step of drying/pulverizing a tobacco plant or non-tobacco plant as a main raw material and weighing, etc., and a preparatory step of pre-treating other raw materials, weighing, etc. , a mixing step of mixing raw materials to form a composition, and a filling molding step of molding the composition.

In the drying and pulverizing step, the used parts of tobacco plants or non-tobacco plants (e.g., leaves, seeds, dried fruits, stems, bark, roots, etc.), which are the main raw materials, are processed into predetermined pulverized products in order to make compositions. . In this case, it is preferable to adjust the water content to be convenient 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 in this range, it is easy to reach the desired amount of water while avoiding the dissipation of the required flavor component. Furthermore, the drying/pulverizing step can be provided with a sieving step for sieving the pulverized material, and the pulverized material can be adjusted to a desired particle size and fed to the mixing step.

In the preparation step, 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.

A normal mixer can be used in the mixing step. For example, it is preferable to use a form in which the raw materials in the mixing tank are mixed with a stirring blade while applying a shearing force.

In the filling forming step, the composition in which various raw materials are mixed is formed into a thin sheet and then cut to form strip-shaped or rod-shaped aerosol-forming substrates 23 . In this embodiment, a plurality of roll mills are prepared in order to obtain a thin sheet. When multiple roll mills are used, it is possible to make a sheet of a desired thickness with a doctor blade while performing kneading and dispersion by compression by being pushed between narrow rolls and shearing by roll speed difference. ,preferable. Moreover, it can also be manufactured using a press roller or a press machine.

In order to obtain the powdery or granular aerosol-forming base material 23, it is preferable to appropriately pulverize or classify the composition. The average particle size of the powdery or granular aerosol-forming substrate 23 is, for example, preferably 0.1 to 3.0 mm, 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. In other words, this average particle diameter is the diameter corresponding to 50% of the mass obtained by accumulating the mass from the larger mesh size of the test results with a plurality of sieves. Alternatively, the average particle size may be the particle size at an integrated value of 50% in the particle size distribution determined by the laser diffraction/scattering method.

Other means may be used in the filling molding step, such as molding the composition through an orifice under pressure. In addition, in the filling molding step, if necessary, non-tobacco plants, aerosol formers, binders or thickeners, flavor additives, preservatives, etc. may be further added, and water etc. may be added. Also good.

The thickness of the sheet obtained in the filling molding 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 into a predetermined width by a cutter, a rotary cutter of rotary blade type, or the like.

Here, in the case of imparting adhesiveness to the surface of the aerosol-forming base material 23, there is no particular limitation as long as it is a means capable of imparting adhesiveness. By imparting adhesiveness, when the strip-shaped or rod-shaped aerosol-forming substrate 23 and the powdery, granular or paste-shaped aerosol-forming substrate 23 are combined, the surface of the strip-shaped or rod-shaped aerosol-forming substrate 23 can be Powdery, granular or pasty aerosol-forming substrate 23 can be stably held.

(Method of using cartridge for smoking device)
A method of using the smoking article cartridge 1 will be described. FIG. 3 is a cross-sectional view of the smoking article cartridge 1 inserted into the smoking article 70. As shown in FIG. The smoking implement cartridge 1 is used by being attached to a heating type smoking implement 70 . The smoking implement 70 has an insertion portion 72 into which the smoking implement cartridge 1 is inserted. The insertion portion 72 is provided with a needle-like or blade-like heating portion 75 . When the smoking device cartridge 1 is inserted into the insertion portion 72 , the heating portion 75 generates heat to generate an aerosol from the aerosol-forming substrate 23 . In this state, when the smoker holds the mouthpiece 40 in his mouth and inhales, the aerosol flows through the through hole 31a of the support member 30 and the mouthpiece 40 in order, and flows into the smoker's mouth.

According to the smoking article cartridge 1 according to the first embodiment configured in this way, the following effects can be obtained.

Since the inner diameter r1 of the support member 30 is smaller than the outer diameter D of the aerosol-forming substrate 23, the thickness of the support member 30 between the inner diameter r1 and the outer diameter R1 allows the object to be heated 20 (the aerosol-forming substrate 23 ). Therefore, the movement of the heated body 20 (aerosol-forming substrate 23) toward the support member 30 can be suppressed.

In addition, the dimension of the outer diameter R1 of the support member 30 and the dimension of the outer diameter D of the heated body 20 (aerosol-forming base material 23) can be set to be the same. can abut the aerosol-forming substrate 23 . Therefore, since the aerosol-forming substrate 23 can be sufficiently supported by the supporting member 30, the movement of the heated body 20 (aerosol-forming substrate 23) toward the supporting member 30 can be further suppressed. In addition, the aerosol-forming substrate 23 can be prevented from moving toward the support member 30 through between the first end portion 30a of the support member 30 and the exterior member 10 .

Also, since the shape of the first end portion 30a of the support member 30 is different from the shape of the second end portion 30b, the shape of the through hole 31a of the support member 30 is not uniform along the central axis C1. Therefore, even if part of the aerosol-forming substrate 23 enters the through-hole 31a, it is difficult for it to move inside.

Furthermore, the inner diameter r1 of the support member 30 is larger than the inner diameter r2, and the diameter of the through hole 31a of the support member 30 is smaller at the second end 30b than at the first end 30a. Therefore, the movement of the aerosol-forming substrate 23 that has entered the inside of the through-hole 31a can be made more difficult.

In addition, since the support member 30 is formed such that the inner diameter gradually decreases from the first end portion 30a toward the second end portion 30b, the aerosol-forming substrate that has entered the through hole 31a of the support member 30 23 collides with the inner peripheral portion of the through hole 31a. Moreover, the escape space of the collided aerosol-forming substrate 23 is limited. Therefore, it is possible to prevent the movement of the aerosol-forming substrate 23 that has entered the through hole 31a.

In addition, since the support member 30 is formed by winding the sheet-like member 31, friction is likely to occur between the aerosol-forming substrate 23 and the sheet-like member 31. FIG. Therefore, the movement of the aerosol-forming substrate 23 that has entered the through hole 31a of the support member 30 can be further prevented.

Furthermore, since the support member 30 has a simple configuration in which the sheet member 31 is rolled into a cylindrical shape, the manufacturing cost can be suppressed.

(Second embodiment)
Next, a smoking article cartridge according to a second embodiment will be described. The smoking implement cartridge 2 according to the second embodiment has basically the same configuration as the smoking implement cartridge 1 according to the first embodiment, except that the support member 30 is made of a truncated cone-shaped resin molding 32. is different. Therefore, in the following description, this difference will be mainly described, and the description that overlaps with the first embodiment will be omitted.

FIG. 4 is a cross-sectional view of the smoking article cartridge 2 according to the second embodiment. As shown in FIG. 4 , the support member 30 (resin molded product 32 ) is arranged so that its lower bottom surface faces the aerosol-forming substrate 23 and its upper bottom surface faces the mouthpiece 40 . The shape of the first end 30a of the support member 30 is different from the shape of the second end 30b. The support member 30 has a truncated cone-shaped through hole 32a therein, and the inner diameter r1 of the support member 30 is larger than the inner diameter r2. Further, the outer diameter R1 of the first end portion 30a of the support member 30 is larger than the outer diameter R2 of the second end portion 30b. Further, a plurality of recesses 32c are formed in the outer peripheral surface 32b of the support member 30. As shown in FIG. A plurality of protrusions may be formed instead of the plurality of recesses 32c.

Next, the relationship between the outer diameter R1 and inner diameter r1 of the support member 30 and the outer diameter D of the aerosol-forming substrate 23 will be described with reference to FIG. The drawing on the left side of FIG. 5 is a longitudinal section of the aerosol-forming substrate 23 taken along line VV of the smoking device cartridge 2 shown in FIG. 4 and viewed from the support member 30 side. The drawing on the right side is a longitudinal section of the support member 30 viewed from the aerosol-forming substrate 23 side.

As shown in FIG. 5, both the outer diameter R1 of the support member 30 (resin molded article 32) and the outer diameter D of the aerosol-forming substrate 23 correspond to the length between L1 and L4. The inner diameter r1 of the support member 30 is the length between L2 and L3, that is, the outer diameter R1 (=outer diameter D) of the support member 30 minus the thickness (2Δr) of the thick portion of the support member 30. Equivalent to length.

According to the smoking implement cartridge 2 according to the second embodiment configured in this manner, the same effects as those of the above-described first embodiment can be obtained. Furthermore, according to the second embodiment, since the outer diameter R1 of the support member 30 is larger than the outer diameter R2, the support member 30 can contact the one end 23a of the aerosol-forming substrate 23 over a large area. In particular, since the support member 30 is made of the truncated cone-shaped resin molding 32, the thick portion of the support member 30 can reliably support the one end 23a of the aerosol-forming substrate 23, and the object to be heated 20 (the aerosol-forming substrate 23 ) toward the support member 30 can be reliably suppressed.

In addition, since a plurality of recesses 32c are formed on the outer peripheral surface 32b of the support member 30, the support member 30 can be easily gripped during manufacturing of the smoking implement cartridge 2, and the manufacturing efficiency can be improved. Of course, a plurality of protrusions may be formed instead of the plurality of recesses 32c, and the same effect can be obtained in that case as well.

Although the inner diameter r1 of the support member 30 is larger than the inner diameter r2 in FIG. 4, the configuration is not limited to this. If one end 23a of the aerosol-forming substrate 23 can be supported by the thickness of the support member 30 (resin molded product 32), the inner diameter r2 of the support member 30 is equal to or larger than the inner diameter r1. good. If the inner diameter r2 of the support member 30 is equal to the inner diameter r1, the inner diameter of the support member 30 may be uniform from the first end 30a to the second end 30b. Further, when the inner diameter r2 of the support member 30 is larger than the inner diameter r1, the inner diameter of the support member 30 may increase from the first end portion 30a to the second end portion 30b, or may increase from the first end portion 30a to the second end portion 30b. from the second end 30b. Furthermore, the outer diameter R1 and the outer diameter R2 of the support member 30 may be the same regardless of whether the inner diameter r2 of the support member 30 is equal to the inner diameter r1 or larger than the inner diameter r1.

(Third Embodiment)

It differs from the first embodiment in that it has a portion 33b.

Each of the four ridges 33b forms a cut diagonally with respect to the longitudinal direction in a part (four places) of the outer peripheral surface 33c of the sheet member 33, and bends the cut portion inward. formed by The four ridges 33b extend along the central axis C1 and are arranged at equal intervals (at intervals of 90 degrees) in the circumferential direction of the support member 30 (see FIG. 7 described later). Each protrusion 33b is formed such that the width W1 on the side of the first end 30a of the support member 30 is narrower than the width W2 on the side of the second end 30b. Moreover, the width of each protrusion 33b gradually widens from the first end 30a of the support member 30 toward the second end 30b. The shape of the first end portion 30a of the support member 30 is different from the shape of the second end portion 30b.

The width W1 of the support member 30 is preferably in the range of, for example, 0.5 mm to 4.0 mm, more preferably in the range of 1.0 mm to 3.0 mm. If the width W1 is set to 0.5 mm or more, it is possible to secure the minimum necessary width of the support member 30 to support the object to be heated 20. FIG. Further, if the width W1 is set to 1.0 mm or more, it is possible to secure a sufficient width of the support member 30 to support the object to be heated 20. FIG. Furthermore, if the width W1 is set to 4.0 mm or less, it is possible to ensure the minimum size of the channel for the aerosol to flow through the area within the circle C indicated by the dotted line in FIG. Also, if the width W1 is set to 3.0 mm or less, it is possible to ensure a sufficient size of the flow path for the aerosol to flow through the area within the circle C indicated by the dotted line in FIG.

The width W2 of the support member 30 is preferably in the range of, for example, 0.5 mm to 4.0 mm, more preferably in the range of 1.25 mm to 3.25 mm. If the width W2 is set to 0.5 mm or more, it is possible to secure the minimum necessary width of the support member 30 to support the object to be heated 20. FIG. Further, if the width W2 is set to 1.25 mm or more, it is possible to secure a sufficient width of the support member 30 to support the object to be heated 20. FIG. Furthermore, if the width W2 is set to 4.0 mm or less, it is possible to secure the minimum required size of the flow path for the aerosol to flow through the area within the circle C′ indicated by the dotted line in FIG. . Also, if the width W2 is set to 3.25 mm or less, it is possible to ensure a sufficient size of the flow path for the aerosol to flow through the area within the circle C' indicated by the dotted line in FIG.

When manufacturing the support member 30, the size of the flow path of the support member 30 can be adjusted by appropriately selecting the widths W1 and W2 within the above ranges. In addition, by adjusting the support strength of the heated body 20 (aerosol-forming base material 23 ) by the support member 30 , the heated body 20 can be appropriately supported according to the material of the aerosol-forming base material 23 .

Hereinafter, for convenience of explanation, of the four ridges 33b, the ridge 33b formed on the top of the support member 30 (sheet-like member 33) will be referred to as a "first ridge 331b". The ridges 33b formed at positions rotated clockwise every 90 degrees with respect to the ridges 331b are sequentially referred to as a "second ridge 332b", a "third ridge 333b", and a "fourth ridge". ridge portion 334b”.

Next, the relationship between the outer diameter R and inner diameter r1 of the support member 30 and the outer diameter D of the aerosol-forming substrate 23 will be described with reference to FIG. 7 is a longitudinal section of the aerosol-forming substrate 23 taken along line VII-VII of the smoking device cartridge 3 shown in FIG. 6 and viewed from the support member 30 side.

As shown in FIG. 7, both the outer diameter R of the support member 30 (the sheet member 33) and the outer diameter D of the aerosol-forming substrate 23 correspond to the length between L1 and L4. In addition, the inner diameter r1 of the support member 30 is the length between L2 and L3 corresponding to the diameter of the circle C, that is, the width of the first protrusion 331b from the outer diameter R (=outer diameter D) of the support member 30. (W1) and the width (W1) of the third ridge portion 333b are excluded. 7, the portion of each protrusion 33b that protrudes inward from the circle C widens from the first end 30a toward the second end 30b of the support member 30. part.

According to the smoking implement cartridge 3 according to the third embodiment configured in this way, the same effects as those of the above-described first embodiment can be obtained. Furthermore, according to the third embodiment, since the support member 30 has a plurality of ridges 33b extending along the central axis C1 on the inner peripheral surface 33a thereof, the aerosol can be generated on the first end 30a side of the support member 30. The formation base material 23 can be firmly supported. In addition, since the plurality of protrusions 33b are arranged at equal intervals in the circumferential direction of the support member 30, the aerosol-forming substrate 23 can be supported in a well-balanced manner.

Further, since the support member 30 is formed by winding the sheet-like member 33, and the plurality of ridges 33b are formed by bending a part of the outer peripheral surface 33c of the sheet-like member 33 inward. , the support member 30 can have a simple structure, and the manufacturing cost can be suppressed.

Note that the support member 30 may be configured by a resin molded product as in the second embodiment. In this case, the plurality of ridges may be formed by resin molding so as to protrude from the inner peripheral surface of the support member 30 . Moreover, the number of the plurality of protrusions 33b is not limited to four, and may be one or more.

Although the width W1 of the support member 30 is formed to be narrower than the width W2 in FIG. 6, the configuration is not limited to this. The width W2 of the support member 30 may be equal to or wider than the width W1 as long as the one end 23a of the aerosol-forming substrate 23 can be supported by the plurality of ridges 33b of the support member 30. When the width W2 of the support member 30 is equal to the width W1, the width from the first end 30a to the second end 30b of the support member 30 is uniform from the first end 30a to the second end 30b. It should be formed in such a way that Further, when the width W2 of the support member 30 is larger than the width W1, the width from the first end 30a to the second end 30b of the support member 30 is halfway from the first end 30a to the second end 30b. , or may gradually increase from the first end portion 30a toward the second end portion 30b.

In the smoking implement cartridge 4 according to the fourth embodiment, a blocking portion 34 is formed at the first end portion 30a of the support member 30 to block axial movement of the heated body 20 (aerosol-forming substrate 23). It is different from the first embodiment in this respect.

The blocking portion 34 is composed of a plurality of (six in this embodiment) protrusions 34a that protrude from the inner peripheral surface of the first end portion 30a of the support member 30 toward the central axis C1. The support member 30 has a cylindrical portion 35 arranged along the central axis C1, and six protruding portions 34a are provided on the cylindrical portion 35 on the side of the aerosol forming substrate 23 . These protruding portions 34a are arranged at equal intervals (at intervals of 60 degrees) in the circumferential direction so as to face one end portion 23a of the aerosol-forming substrate 23 . The shape of the first end portion 30a of the support member 30 is different from the shape of the second end portion 30b.

Hereinafter, for convenience of explanation, of the six protrusions 34a, the protrusion 34a formed on the top of the support member 30 (cylindrical portion 35) will be referred to as a "first protrusion 341a." The protrusions 34a formed at positions rotated clockwise every 60 degrees as a reference are sequentially referred to as "second protrusion 342a", "third protrusion 343a", "fourth protrusion 344a", and "fifth protrusion". portion 345a” and “sixth projecting portion 346a”.

The size of this inner diameter r1 is, for example, 6.5 mm or less.

As shown in FIG. 9, both the outer diameter R of the support member 30 and the outer diameter D of the aerosol-forming substrate 23 correspond to a length between L1 and L4. In addition, the inner diameter r1 of the support member 30 is the length between L2 and L4 corresponding to the diameter of the circle C′, that is, the protrusion of the first projecting portion 341a from the outer diameter R (=outer diameter D) of the support member 30. It corresponds to a value excluding the amount (T) and the length corresponding to the protrusion amount (T) of the fourth protrusion 344a. The amount of protrusion (T) is preferably in the range of, for example, 0.5 mm to 3.5 mm, more preferably in the range of 1.0 mm to 3.25 mm. If the amount of protrusion (T) is set to 0.5 mm or more, it is possible to secure the minimum required amount of protrusion of the support member 30 to support the object to be heated 20 . Further, if the amount of protrusion (T) is set to 1.0 mm or more, it is possible to secure a sufficient amount of protrusion of the support member 30 to support the object to be heated 20 . Furthermore, if the protrusion amount (T) is set to 3.5 mm or less, the minimum size of the flow path is secured for the aerosol to flow in the area within the circle C' indicated by the dotted line in FIG. It becomes possible. Also, if the size of the projection (T) is set to 3.25 mm or less, it is possible to ensure a sufficient size of the flow path for the aerosol to flow through the area within the circle C' indicated by the dotted line in FIG.

Moreover, since the six protruding portions 34a are provided along the circumferential direction of the support member 30 as the blocking portions 34, the outer peripheral portion of the aerosol-forming substrate 23 and a portion within a predetermined range from the outer peripheral portion can be reliably supported.

Moreover, since the six projecting portions 34a are arranged at equal intervals in the circumferential direction, the aerosol-forming substrate 23 can be supported in a well-balanced manner.

Moreover, since the blocking portion 34 (the plurality of protruding portions 34a) may be formed only on the first end portion 30a of the support member 30, the support member 30 can be configured simply, and the manufacturing cost can be reduced.

In addition, in FIG. 8, the blocking portion 34 is formed only on the first end portion 30a side of the support member 30, but may be formed on the second end portion 30b side as well. In this case, the protrusion amount of the blocking portion on the second end 30b side is equal to or different from the protrusion amount (T) of the blocking portion 34 on the first end 30a side. At this time, the blocking portion 34 on the side of the first end portion 30a and the blocking portion on the side of the second end portion 30b may be formed to be connected. When the protrusion amount of the blocking portion on the second end 30b side is equal to the protrusion amount (T) of the blocking portion 34 on the first end 30a side, the blocking portion extending from the first end 30a side to the second end 30b side may be formed so as to be uniform from the first end portion 30a toward the second end portion 30b. Further, when the protrusion amount of the blocking portion on the second end portion 30b side is different from the protrusion amount (T) of the blocking portion 34 on the first end portion 30a side, The amount of projection of the blocking portion may change in size on the way from the first end portion 30a to the second end portion 30b, or may gradually increase from the first end portion 30a to the second end portion 30b. can be

(Fifth embodiment)
