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

[0011] (First embodiment) FIG. 1 is a cross-sectional view of a cartridge 1 for a smoking article according to a first embodiment of the present invention. As shown in the figure, the cartridge 1 for a smoking article according to the first embodiment includes the heated body 20 and the support member 3. 0 and a mouthpiece 40. The heated body 20, the support member 30, and the mouthpiece 40 The heated object 20, the support member 30, and the mouse are arranged side by side on the central axis C1. The pieces 40 are wrapped and integrated with the sheet-like exterior member 10. 0 consists of paper, for example.

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

[0013] The object to be heated 20 is a container in which an aerosol-forming base material 23, which is a filler, is wrapped in a sheet-like packaging material 25. The aerosol-forming substrate 23 is exposed at both ends of the cylindrical container 21. That is, both ends of the object to be heated 20 are not covered with a lid member (for example, paper). 25 is made of paper, for example, but any material can be used as long as it is a sheet-like member.

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

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

[0016] Of course, the aerosol-forming substrate 23 is not limited to a strip-shaped member. For example, a rod-shaped member Alternatively, the aerosol-forming substrate 23 may be a powder-like material. The combination of strip-shaped and granular materials, and the combination of strip-shaped and rod-shaped materials , a combination of rod-shaped members and granular members, or a combination of strip-shaped members, rod-shaped members and granular members. In these cases, the amount of raw material for each component may be as small as possible. However, if some of the ingredients are different, the aroma and flavor are improved, which is preferable.

[0017] The mouthpiece 40 is a part that constitutes the mouthpiece of the cartridge 1 for smoking articles, and is made of, for example, paper. The mouthpiece 40 is made of cellulose acetate, which removes fine particles. The heated body 20 may include a filter or the like. A portion of the particulate matter is filtered out by the filter in the mouthpiece 40 .

[0018] The support member 30 includes a first wall portion 31 and a shaft portion 34. The support member 30 is made of, for example, a silicone. It is made of a cone, and the first wall portion 31 and the shaft portion 34 are integrally formed. In addition, when the shaft portion 34 is provided separately from the first wall portion 31, The construction of 34 may be, for example, a roll of paper or a crimped polymer sheet. It is possible.

[0019] The first wall portion 31 is formed in a disk shape. The diameter of the first wall portion 31 is set to the aerosol-forming group. The diameter of the aerosol-forming substrate 23 is approximately equal to the diameter of the aerosol-forming substrate 23. When the diameter of the aerosol-forming substrate 23 is equal to the thickness of the packaging member 25, i.e., The concept includes the case where the diameter of the first wall portion 31 is equal to the diameter of the object to be heated 20. The first wall portion 31 may have a diameter smaller than that of the aerosol-forming substrate 23. The first wall portion 31 is disposed at a position facing the aerosol-forming substrate 23, and the end face of the first wall portion 31 faces the aerosol-forming substrate 23. It abuts against the end (end face) of the

[0020] The shaft portion 34 is formed in a cylindrical shape. The shaft portion 34 extends from the first wall portion 31 coaxially with the central axis C1. The end 34a of the shaft 34 extends upward toward the mouthpiece 40. It is in contact with the surface.

[0021] The first wall portion 31 is in contact with the aerosol-forming substrate 23, and the end portion 34a of the shaft portion 34 is connected to the mouthpiece. When the aerosol-forming substrate 23 comes into contact with the base 40, the movement of the aerosol-forming substrate 23 in the axial direction is restricted.

[0022] 2 is a cross-sectional view of the first wall portion 31 taken along the line II-II in FIG. The wall portion 31 has a plurality of (four in this embodiment) through holes (first through holes) 32. The through holes 32 are arranged at equal intervals (90° intervals) along the circumferential direction. These four through holes 32 are used for the air generated by heating the aerosol-forming substrate 23. The through-holes 32 form a first flow path through which the aerosol flows. It is the perfect size for this purpose.

[0023] Furthermore, the space S1 between the shaft portion 34 and the exterior member 10 is a flow path through which the aerosol flows. The space S1 functions as an exchange portion where the aerosols flowing through the through holes 32 exchange with each other, The support member 30 also functions as a cooling section for cooling the aerosol. The generated aerosol is guided to the mouthpiece 40. At this time, the aerosol flows through the stem 34 and The space S1 between the exterior member 10 and the mouthpiece 40 allows air to flow and be cooled. It is then sucked into the smoker's mouth through the

[0024] Here, the thickness of the first wall portion 31 is set to be in the range of about 1 / 3 to 1 / 10 of the length of the shaft portion 34. In this way, the effect of aerosol exchange and cooling by the space S1 can be effectively achieved. This is because the strength of the support member 30 can be ensured while maintaining the same.

[0025] Next, specific examples of the raw material used as the aerosol-forming substrate 23 will be described. The sol-forming substrate 23 is composed of any one or a combination of the following raw materials: will be done.

[0026] The aerosol-forming substrate 23 is made from a tobacco plant or a non-tobacco plant. Examples of tobacco include tobacco leaves, tobacco stems, expanded tobacco, homogenized tobacco, etc. Examples of suitable parts of non-tobacco plants include plants other than tobacco plants. , leaves, pulp, seeds, roots (scaly roots, tuberous roots, etc.), stems, tubers, skin (stem bark, bark, etc.), flowers (petals, male Examples include stamens, pistils, trunks, branches, etc.

[0027] In this specification, "plants" refers to a group of plants, such as grass and trees, as opposed to animals. In addition to organisms that have roots and live in fixed locations, there are also organisms such as microalgae and seaweed. This also includes algae, mushrooms, and other fungi.

[0028] The aerosol-forming substrate 23 is, for example, a dried and crushed non-tobacco plant material. Aerosol former, microcrystalline cellulose, flavor additives, preservatives, The adhesive or thickener is mixed appropriately, and the mixture is crushed or classified to form powder or granules, or the mixture is sealed. After forming it into a ball shape, it is cut into strips or rods with a specified width and length. can be.

[0029] For example, when the non-tobacco plant part is a leaf, tea can be preferably used. Not only are the plants that produce tea different, but even the same plants can produce different teas depending on how they are processed. Specifically, for example, Japanese tea, black tea, Angelica keiskei tea, sweet tea, Gynostemma tea, aloe tea, Ginkgo leaf tea, oolong tea, turmeric tea, salicylic acid tea, Eleuthero tea, plantain tea, Kiodoshi tea, persimmon leaf tea, chamomile tea, chamomile tea, Kawara Ketsumei tea, quince tea, chrysanthemum tea, Gymnema tea, guava tea, wolfberry tea, soft leaf tea, black bean tea, gennoshoko tea, brown rice tea, burdock Tea, comfrey tea, bifu tea, cherry blossom tea, saffron tea, shiitake tea, shiso tea, jasmine tea, Ginger tea, horsetail tea, lily of the valley tea, Swertia japonica tea, buckwheat tea, elm tea, dandelion tea, sweet Tea, Houttuynia cordata tea, Eucommia tea, Sword bean tea, Elderberry tea, Licorice tea, Job's tears tea, Habu tea , Loquat leaf tea, Pu'er tea, Safflower tea, Pine needle tea, Mate tea, Barley tea, Megusurinoki tea, Mugwort tea These teas include eucalyptus tea, monk fruit tea, rooibos tea, and bitter melon tea. You can use used tea leaves after drinking. If you use used tea leaves, you can reuse expensive tea. It can be used effectively.

[0030] Furthermore, extracts of non-tobacco plants, so-called extracts and processed products, can also be used. The extract may be in the form of liquid, syrup, powder, granules, solution, etc.

[0031] The aerosol former used as the raw material for the aerosol-forming base material 23 is glycerin, propylene glycol, propylene glycol, propylene glycol ether ... Glycol, Sorbitol, Triethylene Glycol, Lactic Acid, Diacetin (Glycerin diacetate), triacetin (glycerin triacetate), triethylene glycol diacetate, triethyl citrate, isopropyl myristate, methyl stearate, Examples include dimethyl dodecanedionate and dimethyl tetradecanedione. However, glycerin and propylene glycol are preferred.

[0032] The microcrystalline cellulose used as the raw material for the aerosol-forming substrate 23 is, for example, a fibrous plant cellulose. It is obtained by partially depolymerizing α-cellulose obtained from pulp with acid. It is obtained by removing the soluble portion from cellulose and, if necessary, crystallizing the insoluble portion. .

[0033] The microcrystalline cellulose may be in the form of powder 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 to disperse the material in the solvent.

[0034] Furthermore, if necessary, a flavor additive may be used as a raw material for the aerosol-forming base material 23 to add flavor. Flavoring additives include mint, cocoa, coffee, and black tea extracts, Examples include powdered catechins from tea extract. Preservatives that are used in food are preferred. Examples of suitable benzoates include sorbic acid, potassium sorbate, benzoic acid, and sodium benzoate. It can be obtained.

[0035] The aerosol-forming substrate 23 contains menthol and a water-insoluble cross-linked polymer (preferably poly It may contain vinyl polypyrrolidone. By combining these ingredients, the sublimation of menthol can be effectively suppressed, and the menthol flavor can be maintained for a long period of time. Here, menthol is not limited to that obtained from natural products, but may be a synthetic product. You can also use peppermint, mint, peppermint oil, or other menthol-containing products. good.

[0036] The flavor additive may be added to the mouthpiece 40 by, for example, impregnating the walls of the mouthpiece 40. The flavor additive is provided in the mouthpiece 40. The present invention is not limited to such an embodiment, and may be embodied, for example, by placing a capsule containing the flavor additive in a mouthpiece. The flavor additive is provided in the mouthpiece 40 by being embedded in the wall of the mouthpiece 40. Alternatively, a flavor additive may be enclosed between the mouthpiece 40 and the heated object 20. A capsule 60 containing flavor additives may be placed (see Figs. 19 and 20). When the drug is enclosed in a capsule 60, the smoker can press the capsule 60 with his / her finger. The capsule 60 can be broken, and the aromatic components of the flavor additive can be volatilized at the desired timing. It is possible to do this.

[0037] Furthermore, the flavor additive may be, for example, encapsulated in a microcapsule. The object to be heated 20 may be provided with microcapsules containing the same.

[0038] Examples of binders or thickeners used as raw materials for the aerosol-forming base material 23 include guar gum, chitosan, and the like. Gums such as santa gum, gum arabic and locust bean gum, e.g. hydroxy Propyl cellulose, carboxymethyl cellulose, hydroxyethyl cellulose, Cellulose binders such as starch, aluminum, cellulose, ethyl cellulose, and ethyl cellulose Organic acids such as acetic acid, sodium alginate, sodium carboxymethylcellulose, Polysaccharides such as conjugate base salts of organic acids such as caramel, agar and pectin, and A combination of the following is included.

[0039] (Method of manufacturing an aerosol-forming substrate) The method for producing the aerosol-forming substrate 23 will be explained below in detail, with each step being explained separately. The manufacturing process of the sol-forming substrate 23 is to dry and powder the tobacco plant or non-tobacco plant that is the main raw material. The drying and grinding process involves crushing and weighing, and the preparation process involves pre-processing and weighing of other raw materials. The method includes a mixing step of mixing raw materials to form a composition, and a filling molding step of molding the composition. do.

[0040] In the drying and grinding process, the main raw material, tobacco plant or non-tobacco plant parts (e.g. (e.g., leaves, seeds, dried fruits, stems, bark, roots, etc.) are processed into a specified crushed material to make a composition. At that time, the aerosol former, water, and other components that will be added later will be absorbed or supported. It is preferable to adjust the moisture content to a level that is convenient for drying. By setting the temperature in this range, it is possible to avoid the scattering of the necessary flavor components while maintaining the desired flavor. It is easy to achieve the desired moisture content. Furthermore, the drying and grinding process includes a sieving process to sift the ground material. It is also possible to provide a powder with a desired particle size and then add it to the mixing step.

[0041] In the preparation step, raw materials necessary for producing the aerosol-forming substrate 23 are prepared. The microcrystalline cellulose can be weighed in the preparation step and added to the mixing step. It will be entered.

[0042] In the mixing step, a conventional mixer can be used. For example, A preferred mixing method is to mix the ingredients while applying shear force with a stirring blade.

[0043] In the filling molding process, the composition of the various raw materials is formed into a thin sheet, which is then cut. By cutting, a strip-shaped or rod-shaped aerosol-forming substrate 23 is formed. In order to make a thin sheet, a three-roll mill is used. The material is compressed by being pressed between the rolls and sheared by the difference in roll speed, which causes the material to be kneaded and separated. While performing the above steps, it is possible to form a sheet of the desired thickness using a doctor blade. It is also possible to prepare the film by using a press roller or a press machine.

[0044] In order to prepare the powdery or granular aerosol-forming base material 23, the above composition is preferably It is preferable to crush or classify the powder or granular aerosol-forming base material 23. The average particle size is preferably, for example, 0.1 to 3.0 mm, and is preferably 0.5 mm or less. The average particle size is more preferably, for example, In other words, this average particle size is determined by the sieving method described in Regarding the test results, the mass of the larger opening was calculated and 50% of that mass was used. It also refers to the diameter of the particle that is the cumulative value of 50 in the particle size distribution obtained by the laser diffraction / scattering method. The particle size in % may be used as the average particle size.

[0045] In the filling molding process, the composition is forced through an orifice under pressure to form a shape similar to other processes. In the filling forming step, non-tobacco plants, aerobic plants, etc. may be used as needed. Solformer, binder or thickener, flavor additive, preservative, etc. may be further added. Water or the like may be added.

[0046] The thickness of the sheet obtained in the filling molding step is preferably in the range of 0.1 mm to 1.0 mm. The thickness is preferably in the range of 0.1 mm to 0.5 mm. The sheet is then cut to a predetermined width using a rotary cutter or the like.

[0047] Here, when the surface of the aerosol-forming substrate 23 is to be made adhesive, There is no particular limitation on the means as long as the binder is attached to at least a part of the surface. By providing adhesiveness, the aerosol-forming substrate 23 in the form of a strip or a rod and the powder or granules can be combined. When combined with a strip-shaped or rod-shaped aerosol-forming substrate 23, The aerosol-forming substrate 23 can be stably held in powder or granular form on the surface of the substrate 23. Cut.

[0048] (How to use smoking cartridges) The method of using the cartridge 1 for smoking articles will be described. 1 is a cross-sectional view of the cartridge 1 inserted into a smoking article 70. The smoking tool 70 is used by being attached to the smoking tool cartridge 1. The insertion part 72 is provided with a needle-shaped or blade-shaped heating part 75. When the cartridge 1 for a smoking article is inserted into the insertion portion 72, the heating portion 75 generates heat. In this state, the aerosol is generated from the aerosol-forming substrate 23. When the person holds the mouthpiece 40 in his mouth and inhales, the aerosol flows into the space S1, the mouthpiece 40, and the The liquid flows in order and enters the smoker's mouth.

[0049] The cartridge 1 for a smoking article according to the first embodiment configured as described above has the following advantages. It can bear fruit.

[0050] Since the support member 30 is composed of the first wall portion 31 and the shaft portion 34, the support member 30 is easier to support than the conventional one. The structure of the support member 30 can be simplified, and the manufacturing cost of the support member 30 can be reduced.

[0051] In addition, the support member 30 is interposed between the aerosol-forming substrate 23 and the mouthpiece 40, Since the movement of the aerosol-forming substrate 23 in the axial direction is restricted, the cartridge 1 for the smoking article When inserted into the smoking article 70, the aerosol-forming substrate 23 is prevented from shifting position. Therefore, the heating of the aerosol-forming substrate 23 by the heating unit 75 is stable, and a good aerosol is generated. occurs.

[0052] Furthermore, since the exterior member 10 is supported by the outer peripheral surface of the first wall portion 31, the smoking article car This prevents deformation in the radial direction when the cartridge 1 is grasped with fingers. This prevents deformation in the axial direction when the cartridge 1 for a smoking article is inserted into the smoking article 70. It can be stopped.

[0053] In addition, the aerosol that has passed through the four through holes 32 is cooled while being exchanged in the space S1. This improves the aroma and taste of the aerosol.

A plurality of (for example, four) notches (first notches) 32-1 are provided on the periphery. These four notches 32-1 are arranged at 90-degree intervals in the circumferential direction, and allow aerosols to pass through. Even with this configuration, the same effects as those of the first embodiment described above can be achieved. The number of notches 32-1 is not important. For example, if there is one large notch 32-1, The plurality of notches 32-1 may be different in size.

[0056] (Variation 1-2) 5 is a cross-sectional view of the first wall portion 31-2 according to the modified example 1-2. 5 is a cross-sectional view taken along the same line as line I-II. The outer shape of the first wall portion 31-2 is a regular hexagon when viewed from the direction of the arrow. Six flow paths 32-2 are formed between the wrapped exterior member 10 and the outer periphery of the first wall portion 31-2. These six flow paths 32-2 constitute the first flow path through which the aerosol passes. Even with this configuration, the same effects as those of the first embodiment can be achieved. The outer shape of the wall portion 31-2 may be a polygon other than a regular hexagon.

[0057] (Second embodiment) Next, a cartridge for a smoking article according to a second embodiment of the present invention will be described. The cartridge 2 for a smoking article according to the present embodiment is based on the cartridge 1 for a smoking article according to the first embodiment.
