Description

Non-combustion heating type flavor inhalation article and non-combustion heating type flavor inhalation system

[0001] The present invention relates to a non-combustion and heating type flavor inhalation article and a non-combustion and heating type flavor inhalation system.

[0002] Non-combustion heating flavor inhalation articles are known that are heated without combustion using an electric heater or the like. It is also known to place a breakable capsule (see, for example, WO 2014 / 171433) containing a flavoring inside within the filter material of a combustion flavor inhalation article, such as a cigarette (see, for example, WO 2018 / 011660). A user can crush the capsule from the outside of the filter material with their fingers or teeth to break the capsule, releasing the flavor inside the capsule into the filter material, thereby changing the flavor experienced during inhalation before and after the capsule is broken.

[0003] When a user inhales, a non-combustion heating type flavor inhalation article differs from a combustion type flavor inhalation article such as a cigarette in the following characteristics: - The temperature of the volatilized flavor components that migrate from the aerosol generation segment to the downstream segment during use (inhalation) is high; - The proportion of water vapor among all volatile components is high. Therefore, when a user inhales, the inside of the filter material of the non-combustion heating type flavor inhalation article becomes hot and humid. Furthermore, when a user inhales with a capsule placed in the filter material of a combustion type flavor inhalation article, the area around the capsule tends to become hot and humid. For this reason, it is presumed that the capsule in the filter material of a non-combustion heating type flavor inhalation article tends to soften when the user inhales.

[0004] When a user of a non-combustion heating flavor inhalation article who has inhaled at least once attempts to destroy the capsule, the user may mistakenly believe that the capsule is not contained in a filter material due to the softness of the capsule, or that the capsule has been broken in advance. In addition, capsules formed of multiple layers are generally more likely to be costly than capsules formed of a single layer.

[0005] The present invention aims to provide a non-combustion and heating type flavor inhalation article and a non-combustion and heating type flavor inhalation system that allow a user who has taken at least one inhalation to easily recognize a capsule when attempting to break the capsule.

[0006] A non-combustion heating flavor inhalation article according to one embodiment of the present invention includes an aerosol-generation segment and a mouthpiece segment adjacent to the aerosol-generation segment. The mouthpiece segment includes a filter material and a breakable capsule with a single-layer core-shell structure disposed within the filter material. The capsule has a spherical or nearly spherical shape with a diameter of 3.0 mm to 4.5 mm. When the capsule is stored for 10 minutes under conditions of 45°C and 90% RH, the stress of the capsule at a displacement of 0.5 mm within 4 minutes after storage is 2 N or more and 6 N or less.

A rod containing the capsule used in the test shown in Fig. 9 in the mouthpiece segment was inserted into the heater shown in Fig. 2, and after a user properly inhaled three times, the capsule in the mouthpiece segment was broken.

[0008] As shown in FIG. 1 , the non-combustion heating type flavor inhalation system (electrically heated flavor inhalation system) 10 according to this embodiment differs from traditional cigarettes in that it does not involve combustion, but is a heating type that heats a filler 62 (described later) by, for example, electrical heating, allowing the flavor of the filler 62 to be enjoyed.

[0009] The non-combustion heating type flavor inhalation system 10 includes a heater 12 and a rod (non-combustion heating type flavor inhalation article) 14 that is detachably attached to an insertion portion 42 of the heater 12. The heater 12 is reusable, and the rod 14 is discarded after a single use.

[0010] The heater 12 has a box-shaped housing 22, a battery unit (e.g., a secondary battery) 24, a switch 26 for starting the heater 12, a pressure-sensing unit 28, a heat transfer unit (heat transfer tube) 30, a heater 32 arranged around the heat transfer unit 30, and a control unit 34.

[0011] The housing 22 has an insertion portion 42 and a ventilation hole 44. The insertion portion 42 is formed as a cylindrical recess that conforms to the shape of the rod 14. The ventilation hole 44 connects the outside of the housing 22 with the insertion portion 42, and supplies air to the rod 14 inserted into the insertion portion 42.

[0012] The housing 22 is provided with a battery unit 24 , a switch 26 , a pressure sensing section 28 , a heat transfer section 30 (heat transfer tube), a heater 32 provided around the heat transfer section 30 , and a control section 34 .

[0013] The battery unit 24 is formed as a secondary battery assembly, for example, by combining one or more secondary batteries, and supplies power to the pressure sensing unit 28, the heater 32, the control unit 34, and the like.

[0014] The switch 26 is exposed to the outside of the housing 22 and is provided at a position adjacent to the socket of the socket portion 42 .

[0015] The pressure-sensing section 28 is configured by, for example, a pressure sensor (pressure-sensitive sensor), and is provided, for example, inside the insertion section 42 (inside the ventilation hole 44).

[0016] The heat transfer portion 30 is formed into a hollow cylindrical shape from a metallic material. The metallic material of the heat transfer portion 30 is preferably a metal with high thermal conductivity, such as gold, silver, copper, aluminum, or an alloy using any of these.

[0017] The heater 32 is made of a common electric heating wire such as nichrome wire. The heater 32 is arranged, for example, cylindrically around the heat transfer unit 30. The heating method of the heater 32 is not limited to using Joule heat due to electrical resistance, but may be, for example, an induction heating (IH) method or a method using a chemical reaction such as oxidation heat. When using the IH method, the filler 62 of the aerosol generation segment 52 is covered with, for example, a magnetic metal thin film. When using a method using a chemical reaction, the material and shape of the heat transfer unit may be selected. Even in these cases, the heater 32 can heat the aerosol generation segment 52 without burning it.

[0018] The control unit 34 receives power from the battery unit 24 and controls the switch 26, the pressure-sensing unit 28, the heater 32, etc. The control unit 34 controls the pressure-sensing unit 28 to detect whether the rod 14 is properly inserted into the insertion portion 42 and further detect the negative pressure inside the insertion portion 42 (in the ventilation hole 44). Therefore, the control unit 34 can control the heater 32 not to supply power if the rod 14 is not properly inserted into the insertion portion 42. The control unit 34 can also count the number of inhalations by the user. The control unit 34 supplies power from the battery unit 24 to the heater 32 and adjusts the temperature of the heater 32 within an appropriate range. The control unit 34 controls the heater 32 to heat the aerosol-generating segment 52 of the rod 14 (described later) to, for example, 30°C to 400°C, preferably 100°C to 400°C, and more preferably 150°C to 250°C.

[0019] The rod 14 (non-combustion heating type flavor inhalation article) shown in FIGS. 1 and 2 is formed, for example, in a cylindrical shape.

[0020] The circumferential length of the rod 14 is not particularly limited, but is preferably 16 mm to 25 mm, and more preferably 21 mm to 23 mm. The total length (horizontal length) of the rod 14 is not particularly limited, but is preferably 50 mm to 100 mm, and more preferably 50 mm to 70 mm.

[0021] The rod 14 has an aerosol-generating segment (tobacco portion) 52, a mouthpiece segment 54, and tipping paper (mouthpiece lining paper) 56.

[0022] The aerosol-generation segment 52 includes a filler 62 containing, for example, tobacco, and a paper wrapper 64 formed by wrapping the filler 62 in, for example, a cylindrical shape.

[0023] The tobacco-containing filler 62 is formed by randomly packing dried tobacco leaves or ground tobacco plants into a sheet, which is then chopped into approximately 1 mm x 3 mm pieces. The filler 62 may contain, for example, 0 wt % to 30 wt % of an aerosol source (glycerin, propylene glycol (PG), 1,3-butanediol), and a flavoring material.

[0024] The mouthpiece segment 54 in this embodiment includes a first segment 72 , a second segment 74 , a third segment 76 , a capsule 78 , and a wrapper 80 .

[0025] The first segment 72 is formed from a cardboard tube (200 μm to 500 μm thick) formed into a cylindrical shape. The cardboard may be made from wood pulp, as with ordinary paper, or may be made from cellulose acetate fibers treated with a plasticizer (triacetin) and compressed into a sheet.

[0026] The second segment 74 includes a hollow rod 82 and an inner plug wrapper 84. The hollow rod 82 is formed by densely packing, for example, cellulose acetate fibers. The inner plug wrapper 84 is primarily made of paper and wraps the outer periphery of the hollow rod 82. The cellulose acetate packing layer has a high density. Therefore, during inhalation (smoking), air and aerosols flow through the hollow portion inside the hollow rod 82 and are less likely to flow into the fiber packing layer. The rod 82 may also be formed as a solid structure rather than a hollow structure.

[0027] The cellulose acetate fibers of the hollow rod 82 of the second segment 74 are hardened by adding an appropriate plasticizer, such as triacetin, in an amount of, for example, 6% to 20% by mass relative to the mass of the cellulose acetate. The hollow portion of the second segment 74 has an inner diameter of, for example, 1.0 mm to 5.0 mm.

[0028] The third segment 76 includes a solid rod (filter material) 92 and an inner plug wrapper 94. The solid rod 92 is filled with, for example, cellulose acetate fibers at an appropriate density. The inner plug wrapper 94 is primarily made of paper and wraps around the solid rod 92.

[0029] The solid rods 92 of the third segment 76 may be formed with the same packing density as the cellulose acetate fibers of the hollow rods 82 of the second segment 74, or may be formed with a different packing density. Similarly to the hollow rods 82 of the second segment 74, the cellulose acetate fibers of the solid rods 92 of the third segment 76 preferably contain an appropriate plasticizer, such as triacetin. The filament denier of the cellulose acetate long fibers plasticized with the plasticizer is preferably 3.0 dpf (denier per filament) or more and 12.0 dpf or less. The packing density of the cellulose acetate long fibers plasticized with the plasticizer is preferably 130 mg / cc or less. The packing density of the cellulose acetate long fibers plasticized with the plasticizer is preferably 100 mg / cc or more. Setting the packing density of the cellulose acetate long fibers plasticized with a plasticizer within this range makes it easier to fix the capsules 78 in the correct position, and also prevents the capsules 78 from popping out when the cut-out segments 98 described below are pressed.

[0030] In this embodiment, a capsule 78 is disposed within the solid rod 92 of the third segment 76. The capsule 78 is not limited to being disposed in the third segment 76, but may also be disposed in the first segment 72 or the second segment 74. Furthermore, the capsule 78 may be disposed, for example, in the third segment 76 and / or the first segment 72 and second segment 74. Therefore, one or more capsules 78 may be disposed in one mouthpiece segment 54.

[0031] The capsule 78 has, for example, a shell and a content liquid containing a flavoring. In this embodiment, the capsule 78 is preferably composed of a shell and a content liquid within the shell. The shell can be made of, for example, starch, dextrin, polysaccharides, agar, gellan gum, gelatin, various natural gelling agents, glycerin, sorbitol, calcium chloride, etc., and can further contain flavorings and colorings. The capsule 78 may be surrounded by an opaque inner plug wrapper 94 or tipping paper 56, but may be colored so that the user can recognize it when crushing the capsule 78. In this case, the shell preferably contains a coloring, such as Blue No. 1.

[0032] The flavoring of the liquid content may be any flavoring used in smoking articles, such as menthol, plant essential oils, etc. Major flavorings include menthol, tobacco leaf extract, natural plant flavorings (e.g., cinnamon, sage, herbs, chamomile, kudzu, sweet tea, cloves, lavender, cardamom, clove, nutmeg, bergamot, geranium, honey essence, rose oil, lemon, orange, cinnamon bark, caraway, jasmine, ginger, coriander, vanilla extract, spearmint, peppermint, cassia, coffee, celery, cascarilla, sandalwood, cocoa, ylang-ylang, fennel, anise, licorice, St. John's bread, plum extract, peach extract, etc.), sugars (e.g., glucose, fructose, lactic acid bacteria ... Examples of the fragrance include cocoa powders, cocoa extracts, esters (e.g., isoamyl acetate, linalyl acetate, isoamyl propionate, linalyl butyrate, etc.), ketones (e.g., menthone, ionone, damascenone, ethyl maltol, etc.), alcohols (e.g., geraniol, linalool, anethole, eugenol, etc.), aldehydes (e.g., vanillin, benzaldehyde, anisaldehyde, etc.), lactones (e.g., γ-undecalactone, γ-nonalactone, etc.), animal-derived fragrances (e.g., musk, ambergris, civet, castoreum, etc.), and hydrocarbons (e.g., limonene, pinene, etc.). These fragrances may be used alone or in combination.

[0033] The solvent for the content liquid may be a solvent suitable for the fragrance, such as medium-chain triglyceride (MCT) (specifically, glycerin tricaprylate / caprate), propylene glycol, water, ethanol, etc. The content liquid may further contain other additives such as other solvents, colorants, emulsifiers, thickeners, etc.

[0034] A preferred capsule 78 according to this embodiment has a core-shell structure in which the shell is formed as a single layer, and is preferably formed so as to be breakable by an appropriate pressure (stress) range within an appropriate displacement range. The method for manufacturing the capsule 78 is not particularly limited. For example, a dripping method can be used to produce a capsule 78 with a seamless shell. This method uses a double nozzle, ejecting the content liquid from the inner nozzle and the liquid coating material from the outer nozzle simultaneously, allowing the coating liquid to seamlessly envelop the content liquid. The capsule 78 may be configured such that the content liquid (containing no colorant) is enclosed within a capsule body containing a colorant, and the colorant in the capsule body dissolves and migrates into the content liquid during storage to form a colored internal solution. Alternatively, the internal solution may be ejected using different nozzles. In this case, a triple nozzle may be used to simultaneously eject the inner internal solution from the inner nozzle, the outer internal solution from the middle nozzle, and the liquid coating material from the outer nozzle, thereby producing a capsule 78 with a single shell. Separating the inner and outer internal solutions allows the internal solutions with different properties to be ejected at different temperatures and viscosities. For example, the inner liquid may be a liquid containing a water-soluble flavoring agent, and the outer liquid may be a liquid containing a fat-soluble flavoring agent. Also, an emulsifier may be contained in the inner liquid or the outer liquid.

[0035] The capsule 78 according to this embodiment preferably has a shell ratio (the ratio of the weight of the shell to the weight of the capsule 78) of 25% by weight or less.

[0036] The capsule 78 of this embodiment is preferably not provided with a water-resistant coating and / or a heat-resistant coating on the outer periphery thereof, which allows the capsule 78 to be manufactured inexpensively.

[0037] The capsule 78 may have, for example, a spherical or approximately spherical shape. Here, a sphere includes both a sphere having an approximately circular cross section and an ellipsoid having an elliptical or approximately elliptical cross section. The capsule 78 preferably has a spherical shape having an approximately circular cross section. If the capsule 78 has an approximately circular cross section, the diameter of the capsule 78 may be 3.0 mm to 4.5 mm.

[0038] The second segment 74 and the third segment 76 including the capsule 78 are arranged in order, and the wrapper 80 is wrapped so as to connect the second segment 74 and the third segment 76 .

[0039] The first segment 72, the second segment 74, and the third segment 76, each wrapped in a wrapper 80, are then arranged in this order, and the aerosol-generation segment 52 is arranged on the first segment 72 side. This arrangement is then wrapped with tipping paper (mouthpiece lining paper) 56, the inner surface of which is coated with glue (e.g., vinyl acetate glue) on almost the entire surface. The tipping paper 56 is primarily made of paper. The outer peripheries of the aerosol-generation segment 52 and the first, second, and third segments 74 and 76 of the mouthpiece segment 54 are wrapped with the tipping paper 56. Thus, the mouthpiece segment 54 is connected to the aerosol-generation segment 52 containing the tobacco filler 62 by the tipping paper (mouthpiece lining paper) 56. The tip of the tipping paper 56 may be aligned with the tip of the wrapper 64 (the tip 14a of the rod 14), or may be located between the tip and base of the wrapper 64, as shown in FIG. 1 .

[0040] The total thickness of the wrappers (inner plug wrapper 94, wrapper 80, and tipping paper 56) that form the outer periphery of mouthpiece segment 54 is preferably equal to or less than a predetermined thickness, for example, 100 μm or less. The total thickness of the wrappers of mouthpiece segment 54 is not too thick, so that capsule 78 remains easily recognizable when it is pushed into mouthpiece segment 54 from the outside.

[0041] After the aerosol-generation segment 52 and the mouthpiece segment 54 are connected with the tipping paper 56, one or more perforations 58 (vent holes) for introducing air are formed in the mouthpiece segment 54, for example, at a position corresponding to the first segment 72. The perforations 58 penetrate the paper tube of the first segment 72. The perforations 58 are preferably formed to have a size of about 0.5 mm x 1.5 mm.

[0042] The plurality of perforations 58 are preferably formed so as to be arranged radially when viewed from the central axis of the rod 14. In the present embodiment, the plurality of perforations 58 are arranged in a single row on a circular ring at regular intervals. The plurality of perforations 58 may also be arranged in two rows on two circular rings at regular intervals. The plurality of perforations 58 may also be arranged in one or two rows discontinuously or irregularly.

[0043] The perforation 58 is formed at a position that is located outside the insertion opening of the insertion portion 42 of the heater 12 when the tip 14 a of the rod 14 is inserted into the insertion portion 42 of the heater 12 .

[0044] The solid rod 92 is filled with a fiber-filled layer up to the mouth end 14b of the mouthpiece segment 54. The mouth end 14b of the mouthpiece segment 54 of the rod 14 has an appearance similar to the mouth end of a normal cigarette.

[0045] The operation of the non-combustion heating type flavor inhalation system 10 will now be described.

[0046] As shown in FIG. 2 , the rod 14 is attached to the heater 12 by inserting the tip 14a of the rod 14 into the insertion portion 42 of the heater 12. At this time, a predetermined length of the entire length of the aerosol-generating segment 52 of the rod 14 is properly inserted into the insertion portion 42. In this state, when the user presses the switch 26 to activate the heater 12, the control unit 34 begins various control operations of the pressure-sensing unit 28, heater 32, etc. The control unit 34 supplies power from the battery unit 24 to the heater 32, raising the temperature of the heater 32 and heat transfer unit 30 to a predetermined temperature (e.g., approximately 20°C to 400°C). Here, it is assumed that the temperature of the heater 32 and heat transfer unit 30 is raised to 300°C. As a result, the aerosol-generating segment 52 of the rod 14 is heated, causing the components in the filler 62 to volatilize. In this state, when the user places the mouth end 14b between their lips and begins to inhale, outside air is drawn into the vapor-containing fluid (mainstream smoke) flowing within the mouthpiece segment 54 via the multiple perforations 58. The vapor is then cooled by the air drawn into the first segment 72 through the perforations 58 and quickly aerosolized (transformed into minute droplets). When the user inhales, the air and aerosol pass through the fiber-packed layer, and a portion of the aerosol is filtered by the solid rod 92. In this way, vapor (aerosol) containing the flavor of the tobacco filler 62 is released from the aerosol-generation segment 52 into the user's mouth, allowing the user to enjoy the flavor of the filler 62.

[0047] The control unit 34 counts the time since starting various controls of the pressure sensing unit 28, heater 32, etc. The control unit 34 senses the negative pressure inside the housing 22 via the pressure sensing unit 28 and counts the number of times the user has performed suction. The control unit 34 controls the heater 32 to stop heating when a predetermined time has passed or when the user has performed suction a predetermined number of times.

[0048] In this way, the non-combustion heating type flavor inhalation operation of one rod 14 is completed by the heating type flavor inhalation system 10. Then, the user removes the used rod 14 from the insertion portion 42, inserts a new rod 14 into the insertion portion 42, and operates the heater 12 as described above, allowing the user to again enjoy the tobacco flavor from the new rod 14.

[0049] Thus, in the case of this embodiment, it has been found that when a user using the heater 12 and rod 14 described above inhales at least once from the mouthpiece end 14b, the inside of the solid rod (filter material) 92 of the third segment 76, i.e., the area around the outer periphery of the capsule 78, becomes hot and humid.

[0050] FIG. 3 shows a graph of the number of puffs taken by a user using the heated flavor inhalation system 10 according to this embodiment, plotted on the horizontal axis against the amount of moisture supplied to the solid rod 92 of the third segment 76 on the vertical axis. In this embodiment, it can be seen that the amount of moisture supplied to the solid rod 92 is greatest between one and three puffs. Furthermore, when using the heater 12 and rod 14 described above, it has been found that the area around the outer periphery of the capsule 78 within the solid rod 92 near the mouth end 14b of the rod 14 reaches a high-temperature, high-humidity state of approximately 45°C and 90% RH after one to three puffs. This is known to be higher than the temperature within the filter material near the mouth end of a cigarette and higher than the humidity within the filter material near the mouth end of a cigarette. For example, in the initial puffs on a cigarette, the average moisture content per puff is approximately 0.8 mg / 55 ml. This is about ⅕ to ⅓ of the amount of moisture per puff during the initial puff when using the heated flavor inhalation system 10. It has also been confirmed that there is no temperature rise near the mouth end of the cigarette during the initial puff. This is because the end of the cigarette opposite the mouth end is burning, and the generated smoke is sufficiently cooled while passing through the tobacco portion of the cigarette.

[0051] As shown in FIGS. 1, 2, and 4, a rod (hereinafter referred to as a cut-out segment 98) is prepared by cutting out only a segment in which a capsule 78 is disposed from a rod containing a capsule (which may be the same as the rod 14 described above, or a combustion-type flavor inhalation product such as a cigarette). For ease of explanation, it is assumed that the rod 14 described above shown in FIGS. 1 and 2 is used as the rod. Here, it is assumed that the rod 14 is stored at room temperature before being used for heat-type flavor inhalation. Thereafter, a cut-out segment 98 in which the capsule 78 is disposed within the solid rod 92 is cut out from the rod 14 with the tipping paper 56 still wrapped around it. Using a rheometer 100 (Sun RHEO METER CR-3000EX-L (Sun Scientific Co., Ltd.)) shown in FIG. 4, the tipping paper 56 of the cut-out segment 98 cut from the rod 14 was pressed toward the central axis of the cut-out segment 98, and the repulsive force of the cut-out segment 98 was measured. The cut-out segment 98 is formed as a cylindrical body, and the center of the capsule 78 is located on the central axis of the cut-out segment 98. That is, the cut-out segment 98 is cylindrical, and the capsule 78, solid rod (filter material) 92, inner plug wrapper 94, wrapper 80, and tipping paper 56 are arranged in this order from the center outward in the radial direction.

[0052] The rheometer 100 has a pair of disks 102, 104 spaced apart vertically. The pair of disks 102, 104 have opposing, parallel surfaces 102a, 104a. The diameters of these surfaces 102a, 104a are 15 mm. A pressing shaft 106 is connected to the upper disk 104, and the pressing shaft 106 moves axially along the vertical direction, for example, at a uniform speed. The pressing shaft 106 and the upper disk 104 do not rotate around the axis of the pressing shaft 106. The lower disk 102 is fixed. Therefore, as the pressing shaft 106 moves axially, the upper surface 104a approaches or moves away from the lower surface 102a. Here, the pressing shaft 106 of the rheometer 100, i.e., the upper surface 104a, is controlled to move downward at a uniform speed of 20 mm / min.

[0053] The cut-out segment 98 was then placed between the surfaces 102a and 104a of the rheometer 100 shown in Figure 4, and the capsule 78 was placed on the axis of the pressing shaft 106. That is, the tipping paper 56 was brought into contact with the surfaces 102a and 104a, and the pressing shaft 106 was moved vertically downward in this state, applying a pressing force toward the central axis of the cut-out segment 98. As shown in Figure 5, a graph was obtained in which the horizontal axis represents the pressing rate and the vertical axis represents the repulsive force. The pressing rate will be briefly explained using Figure 6. The diameter of a sphere such as a capsule or a cylindrical body such as the cut-out segment 98 in an unloaded state is defined as L1. With a sphere or cylinder supported on the lower surface 102a of the rheometer 100, the pressing shaft 106 connected to the disk 104 is moved vertically downward using the upper surface 104a to press the sphere or cylinder. The length between the top and bottom of the sphere or cylinder, i.e., the distance between the surfaces 102a and 104a, is defined as L2. In this case, (L1-L2) / L1 is the pressing rate.

[0054] The repulsive force shown on the vertical axis of Fig. 5 is not a substantial magnitude but a ratio. In the example shown in Fig. 5, the repulsive force when the capsule 78 in the cut-out segment 98 is broken is set to 1.

[0055] When an external force is applied vertically toward the central axis of the cut-out segment 98 in an attempt to break the capsule 78 inside the filter material (solid rod) 92, the tipping paper 56, wrapper 80, inner plug wrapper 94, filter material 92, and capsule 78 are compressed in this order. During this process, the outer diameter of the capsule 78 is maintained at a constant level, while the tipping paper 56, wrapper 80, inner plug wrapper 94, and filter material 92 are compressed and thinned. After or while the tipping paper 56, wrapper 80, inner plug wrapper 94, and filter material 92 are compressed, the capsule 78 is compressed and deformed. During this process, the tipping paper 56, wrapper 80, inner plug wrapper 94, and filter material 92 maintain their appropriately thinned state or become even thinner, while the capsule 78 is compressed to change from a spherical shape to a flattened shape. It is assumed here that the repulsive force of the tipping paper 56, wrapper 80, and inner plug wrapper 94 caused by the pressing of the cut-out segment 98 is negligibly small compared to the repulsive force of the filter material 92 or capsule 78.

[0056] In the example shown in FIG. 5 , an inflection point indicated by the symbol α appears on the graph at a position between the compression ratio of 0.2 and 0.3. The slope of the graph becomes steeper after the inflection point α compared to before the inflection point α. This is presumably because, at the inflection point α, the tipping paper 56, wrapper 80, inner plug wrapper 94, and filter material 92 of the extrusion segment 98 are in a state equivalent to or close to being fully compressed. If the pressing action of the extrusion segment 98 by the rheometer 100 is a pressing action by a user's finger, it is presumed that, at the inflection point α, the user perceives a repulsive force from the capsule 78's coating with the finger or the like. It is presumed that, after the inflection point α, the user feels as if the capsule 78's coating is being deformed via the tipping paper 56, wrapper 80, inner plug wrapper 94, and filter material 92.

[0057] 5, the capsule 78 was broken at the position indicated by the symbol β, where the pushing ratio was between 0.4 and 0.5. In this case, the capsule 78 was broken before the outer diameter of the cut-out segment 98 reached half.

[0058] In the example shown in FIG. 5 , the repulsive force immediately after the capsule 78 is broken stops at a value γ, not decreasing to the repulsive force corresponding to the inflection point α, then begins to increase again, exceeding the repulsive force at the position indicated by the symbol β at the time the capsule 78 is broken. When the capsule 78 is broken, the repulsive force decreases from a ratio of 1 to approximately 0.6, then increases again. A large drop in the repulsive force (repulsive force difference H) at this time can be said to make the sensation of breaking the capsule 78 more easily conveyed to the user. Note that in the experiment measuring the repulsive force of the cut-out segment 98 shown in FIG. 4 , only the cut-out segment 98 was pressed. This prevents the rod 14 from simultaneously pressing the segments that were integrated with the cut-out segment 98 before the cut-out segment 98 was broken. Therefore, the graph shown in FIG. 5 can eliminate the influence of the material of the segments that were integrated with the cut-out segment 98.

[0059] For comparison, a rod 214 having a mouthpiece segment 254 without a capsule was prepared as shown in FIG. 7 . A cut-out segment 298 corresponding to the cut-out segment 98 described above was cut out from the vicinity of the mouth end of the rod 214. The structure of the cut-out segment 298 was the same as that of the cut-out segment 98 (see FIGS. 1, 2, and 4 ), except that the capsule 78 was not present and the portion where the capsule 78 was not present was solidified with filter material. Therefore, the tipping paper, wrapper, inner plug wrapper, and filter material used in the cut-out segment 298 were assumed to be the same as the tipping paper 56, wrapper 80, inner plug wrapper 94, and filter material 92 used in the cut-out segment 98. The rheometer 100 shown in FIG. 7 is the same as the rheometer 100 shown in FIG. 4 and operates in the same manner.

[0060] Figure 8 shows the relationship between the indentation rate and the repulsive force when the cut-out segment 298 of the rod 214 is compressed using the rheometer 100. In the example shown in Figure 8, the capsule 78 shown in Figure 4 does not exist, and therefore it is assumed that there is no point where the slope of the repulsive force changes abruptly even when the indentation rate increases compared to the example shown in Figure 5. In other words, the inflection point α shown in Figure 5 does not exist in the example shown in Figure 8.

[0061] Furthermore, even if a capsule 78 is present within the cut-out segment 298 shown in FIG. 7 , if the capsule 78 is as soft as or softer than the compressed filter material, the capsule 78 will likely be compressed together with the tipping paper, wrapper, inner plug wrapper, and filter material, resulting in a flattened state. Therefore, if the capsule 78 is softer than the compressed filter material, it is expected that there will be no point at which the slope of the repulsive force changes abruptly even when the compression rate increases. Note that in the experiment measuring the repulsive force of the cut-out segment 298 shown in FIG. 7 , only the cut-out segment 298 was pressed. This prevents the rod 214 from being pressed against the segments that were integrated with the cut-out segment 298 before the cut-out segment 298 was cut. Therefore, the graph shown in FIG. 8 eliminates the influence of the material of the segments that were integrated with the cut-out segment 298.

[0062] Therefore, it is assumed that when the capsule 78 is appropriately hard relative to the filter material 92, the inflection point α shown in Figure 5 appears in the cut-out segment 98 of the rod 14. That is, the slope before and after the inflection point α increases after the inflection point α compared to before the inflection point α, and the greater the change in slope, the easier it is to recognize the presence of the capsule 78. Furthermore, if the repulsive force of the capsule 78 at the initial stage of compression is small (weak) and the shell of the capsule 78 is soft, the inflection point α is less clear. Therefore, even if a user compresses the capsule 78 with their fingers in addition to the tipping paper 56, wrapper 80, inner plug wrapper 94, and filter material 92, they may mistakenly believe that only the tipping paper 56, wrapper 80, inner plug wrapper 94, and filter material 92 are compressed and that the capsule 78 is not being pressed, making it difficult to recognize the presence of the capsule 78. Therefore, it is preferable that the capsule 78 used in the rod 14 of the heating type flavor inhalation system 10 has a large repulsive force at the initial stage of compression in the above-mentioned high temperature and high humidity conditions.

[0063] The left diagram of Figure 9 shows a device 110 capable of maintaining an appropriate temperature and humidity within its internal space. In this device 110, a temperature and humidity corresponding to the temperature and humidity experienced when inhaling from the mouthpiece end 14b of the rod 14 using the heated flavor inhalation system 10 according to the present embodiment were recreated, and a capsule 78 was then stored therein. Specifically, the temperature inside the device 110 was set to 45°C and the humidity to 90% RH, and the capsule 78 was stored therein for 10 minutes. Thereafter, the capsule 78 was subjected to the same measurements as described above using the rheometer 100 at room temperature and normal pressure. The measurements were performed so that the capsule 78 was broken and the measurement was completed within four minutes after removal from the device 110. Note that the temperature and humidity inside the device 110 may vary within a range of, for example, a few percent from the target temperature and humidity (e.g., 45°C and 90% RH).

[0064] Here, three types of capsules 78 with different compositions but the same or substantially the same outer diameter were prepared, and the above-described measurements were performed on the capsules 78 using the rheometer 100 described above, without using the tipping paper 56, wrapper 80, inner plug wrapper 94, or filter material 92 (see FIGS. 1 and 2 ). Although not shown, for convenience, the three types of capsules 78 with different compositions are referred to as a first capsule 78a (preferred embodiment), a second capsule 78b (Comparative Example 1), and a third capsule 78c (Comparative Example 2). Here, the shell composition of the first capsule 78a was 90% deacylated gellan gum, 8% oxidized starch, and 2% calcium chloride. The shell composition of the second capsule 78b was 46% dextrin, 38% gelatin, 14% deacylated gellan gum, and 2% calcium chloride. The shell composition of the third capsule 78c is 50% carrageenan, 35% oxidized starch, 13% glycerin, and 2% calcium chloride.

[0065] Fig. 10 shows the measurement results, i.e., the entire measurement graph, of the displacement (mm) and repulsive force (N) of three types of capsules 78 (capsules 78a, 78b, and 78c) with different compositions, using a rheometer 100. Fig. 11 shows an enlarged view of the area surrounded by the dashed line indicated by the symbol XI in Fig. 10.

[0066] 10 and 11, the first capsule 78a, the second capsule 78b, and the third capsule 78c have significantly different stresses (repulsive forces) (N) in response to an initial displacement of, for example, 1 mm or less. The greater the stress in response to the displacement, the harder the capsule 78 is perceived by the user.

[0067] Furthermore, the first capsule 78a and the second capsule 78b broke at approximately 1.5 mm, while the third capsule 78c broke at a distance exceeding 2 mm. A rod 14 including the first capsule 78a, a rod 14 including the second capsule 78b, and a rod 14 including the third capsule 78c were prepared. These capsules 78a, 78b, and 78c were not exposed to high temperatures and humidity, such as the aforementioned 45°C and 90% RH. Figure 12 shows the results of a sensory evaluation (blind evaluation) by seven experts on the breakability of each capsule 78a, 78b, and 78c in the rod 14. Specifically, an unused rod 14 was appropriately placed in the heater 12, and after three appropriate puffs, the breakability of each capsule 78a, 78b, and 78c was evaluated. At this time, each capsule 78a, 78b, and 78c was exposed to high temperatures and humidity, such as 45°C and 90% RH. The scoring criteria were a good fit with a rating of "5" and a bad fit with a rating of "1." The test results in FIG. 12 are average values.

[0068] The first capsule 78a was evaluated as being easier to break than the second capsule 78b and the third capsule 78c. The second capsule 78b was evaluated as being harder to break than the first capsule 78a, but easier to break than the third capsule 78c. The third capsule 78c was evaluated as being harder to break than the second capsule 78b and the third capsule 78c.

[0069] As described above, the first capsule 78a was evaluated as being more comfortable to break than the second capsule 78b and the third capsule 78c. This is presumably due to the greater magnitude of stress at break relative to the displacement shown in FIG. 10 . It is presumed that the greater the magnitude of stress relative to the displacement, the greater the difference in height H between points β and γ shown in FIG. 5 . It is presumed that the greater and more rapid the change in stress value, the better the user will feel when breaking the capsule 78. Furthermore, the first capsule 78a experiences a higher stress relative to the initial displacement than the second capsule 78b and the third capsule 78c. Therefore, it is presumed that the user will perceive the first capsule 78a as being appropriately hard. In other words, it is presumed that when the first capsule 78a is placed within the mouthpiece segment 54 of the rod 14, the user will more easily recognize the inflection point at point α shown in FIG. 5 compared to when using the second capsule 78b and the third capsule 78c. It is assumed that the displacement from when the first capsule 78a began to deform until it broke was neither too small nor too large. Therefore, it is assumed that the first capsule 78a was able to be broken within the displacement range in which the user's expectations were high, from when the user realized that they were pressing the first capsule 78a with their fingers, teeth, etc., until it broke. Therefore, it is assumed that the user gave a favorable evaluation of the first capsule 78a (and the rod 14 including it).

[0070] It is also assumed that the time from when the first capsule 78a began to deform to when it broke was neither too short nor too long. Therefore, it is assumed that the first capsule 78a was broken within the time range in which the user's expectations were high, from when the user realized that they were pressing the first capsule 78a with their fingers, teeth, etc. to when it broke. Therefore, it is assumed that the user gave a favorable evaluation of the first capsule 78a (and the rod 14 including it).

[0071] As described above, the second capsule 78b was evaluated as being less breakable than the first capsule 78a but more breakable than the third capsule 78c. As shown in FIG. 11 , the second capsule 78b is smaller and softer than the first capsule 78a at an initial displacement of up to 1 mm. Therefore, when using the second capsule 78b, it is expected that the difference in slope before and after the inflection point α shown in FIG. 5 will be smaller than when using the first capsule 78a. This suggests that it is more difficult for the user to recognize that they are pressing the second capsule 78b than when using the first capsule 78a, resulting in a delayed recognition. Furthermore, it is expected that the stress at the time of breaking is lower when using the second capsule 78b than when using the first capsule 78a, and the difference in height H between points β and γ shown in FIG. 5 will be smaller. It is estimated that this is why the breakability of the second capsule 78b in the rod 14 was rated lower than the breakability of the first capsule 78a in the rod 14.

[0072] As described above, the third capsule 78c was evaluated as being less breakable than the second capsule 78b and the third capsule 78c. As shown in FIG. 11 , at an initial displacement of up to 1 mm, the third capsule 78c is smaller and softer than the first capsule 78a. Therefore, when using the third capsule 78c, it is expected that the difference in slope before and after the inflection point α shown in FIG. 5 will be smaller than that of the first capsule 78a. This suggests that the user will be slower to recognize that they are pressing the third capsule 78c than when using the first capsule 78a. Furthermore, it is expected that the stress at the time of breaking will be lower when using the third capsule 78c than when using the first capsule 78a, and the difference in height H between points β and γ shown in FIG. 5 will be smaller. This suggests that the breakability of the third capsule 78c within the rod 14 was evaluated as being lower than that of the first capsule 78a within the rod 14. Furthermore, the displacement of the third capsule 78c from the start of deformation to its breakage was larger than that observed when the first capsule 78a and the second capsule 78b were used. Therefore, it is assumed that the third capsule 78c broke outside the peak of the displacement range in which the user's expectations were rising, from when the user recognized that they were pressing the third capsule 78c until its breakage. For example, it is assumed that the user felt that no breakage occurred despite pressing the outside of the rod 14 toward the central axis with an appropriate stroke, and therefore the user's expectations of the capsule 78 breaking decreased before it broke. Therefore, it is assumed that the user gave a poor rating to the first capsule 78a and the second capsule 78b. Alternatively, it is assumed that the third capsule 78c broke without the user being aware that they were pressing the third capsule 78c. Therefore, it is assumed that the third capsule 78c broke without raising the user's expectations of breaking the third capsule 78c. Therefore, it is presumed that the user gave a bad rating to the first capsule 78a and the second capsule 78b. It is presumed that the displacement (2 mm or more) from when the third capsule 78c started to deform until it broke was too large.Therefore, it is presumed that the third capsule 78c broke at a displacement that exceeded the range of increased user expectations from the time the user recognized that they were pressing the third capsule 78c with their fingers, teeth, etc. until it broke, and thus broke at a displacement that lowered the user's expectations. Therefore, it is presumed that the user gave a poor rating to the ease of breaking the third capsule 78c (including the rod 14). It is also presumed that the time from when the third capsule 78c began to deform until it broke was too long. Therefore, it is presumed that the third capsule 78c broke at a time that exceeded the range of increased user expectations from the time the user recognized that they were pressing the third capsule 78c with their fingers, teeth, etc. until it broke, and thus broke at a time that lowered the user's expectations. Therefore, it is presumed that the user gave a poor rating to the ease of breaking the third capsule 78c (including the rod 14).

[0073] Therefore, it can be said that it is most preferable to use a rod 14 having a mouthpiece segment 54 in which the first capsule 78a according to this embodiment is disposed within the third segment 76 with the heater 12. That is, when the capsule 78 is stored for 10 minutes at 45°C and 90% RH, it is preferable that the capsule 78 stored within 4 minutes has a first capsule 78a with a stress of 2N or more at a displacement of 0.5 mm, which is greater than that of the second capsule 78b and the third capsule 78c. Furthermore, it is preferable that the first capsule 78a has a stress of 6N or less at a displacement of 0.5 mm, which is the greatest repulsive force available with current manufacturing technology. It is more preferable that the displacement of the first capsule 78a at a displacement of 0.5 mm is 2.5N or more and 6N or less. This provides a rod 14, i.e., a non-combustion heating flavor inhalation article, that allows a user who has taken at least one inhale to easily recognize the first capsule 78a when attempting to break it. Furthermore, when the capsule 78 is stored for 10 minutes under conditions of 45°C and 90% RH, it is preferable that the first capsule 78a used within 4 minutes of storage has a stress of 3N or more at a displacement of 1 mm, which is greater than that of the second capsule 78b and the third capsule 78c, and 20N or less, which is the greatest resilience available under current manufacturing technology. It is more preferable that the displacement of the first capsule 78a at a displacement of 1 mm is 4N or more and 20N or less. It is preferable that the first capsule 78a be formed so that it breaks at a displacement of 1mm or more and 2mm or less, so that the user feels that the stroke of the user's finger or teeth after recognizing it is neither too small nor too large. These also provide a rod 14, i.e., a non-combustion heating type flavor inhalation article, that allows a user who has taken at least one inhalation to easily recognize the first capsule 78a when attempting to break the first capsule 78a.

[0074] The coating of the first capsule 78a, which, when stored for 10 minutes under conditions of 45°C and 90% RH, exhibits a stress of 2 N to 6 N when the displacement is 0.5 mm within 4 minutes after storage, and a stress of 3 N to 20 N when the displacement is 1 mm, can be made of, for example, starch, dextrin, polysaccharides, agar, gellan gum, gelatin, carrageenan, various natural gelling agents, glycerin, sorbitol, calcium chloride, etc., and can further contain flavorings and colorings. The first capsule 78a is manufactured using appropriate materials and according to an appropriate recipe so that, when stored for 10 minutes under the above-mentioned conditions of 45°C and 90% RH, the stress of 2 N to 6 N when the displacement is 0.5 mm within 4 minutes after storage, and a stress of 3 N to 20 N when the displacement is 1 mm, can be made of, for example, starch, dextrin, polysaccharides, agar, gellan gum, gelatin, carrageenan, various natural gelling agents, glycerin, sorbitol, calcium chloride, etc., and can further contain flavorings and colorings. The first capsule 78a is manufactured using appropriate materials and according to the above-mentioned conditions of 45°C and 90% RH, and satisfies the above-mentioned conditions of 2 N to 6 N when the displacement is 0.5 mm within 4 minutes after storage, and a stress of 3 N to 20 N when the displacement is 1 mm. Preferably, the coating contains gellan gum and starch, and the weight ratio of gellan gum to starch in the coating (gellan gum:starch) is preferably 50:1 to 1:1, more preferably 10:1 to 3:2. Preferably, the gellan gum is deacylated gellan gum, and the starch is oxidized starch.

[0075] The first capsule 78a suitable for the rod 14 of the heating-type flavor inhalation system 10 according to this embodiment has a shell ratio of 25% by weight or less, and is seamlessly formed containing polysaccharides. Therefore, the weight of the shell of the first capsule 78a can be made relatively small, i.e., the shell can be hardened while preventing the shell from becoming too thick. The shell thickness can be adjusted by changing the temperature, viscosity, and discharge rate of the liquid coating material and inner solution when manufacturing the capsules by the dropping method.

[0076] The first capsule 78a preferably has a ratio of the diameter of the first capsule 78a to the cross-sectional diameter of the filter material 92 of 45% or more and 70% or less. When the ratio of the diameter of the first capsule 78a to the cross-sectional diameter of the filter material 92 is 45% or more, the diameter of the first capsule 78a is an appropriate size that is more than half the diameter of the mouthpiece segment 54. This allows the user to easily recognize the first capsule 78a. Furthermore, when the ratio of the diameter of the first capsule 78a to the cross-sectional diameter of the filter material 92 is 70% or less, the pressure loss in the mouthpiece segment 54 before the first capsule 78a breaks can be prevented from being too large. When the ratio of the cross-sectional diameter of the filter material 92 exceeds 70%, the first capsule 78a is easily recognized before breakage, but inhalation may be difficult. For this reason, it is preferable that the ratio of the diameter of the first capsule 78a to the cross-sectional diameter of the filter material 92 be 70% or less. When the first capsule 78a is a sphere with a diameter of 3.0 mm, the diameter of the mouthpiece segment 54 is approximately 4.2 mm to 6.7 mm. When the first capsule 78a is a sphere with a diameter of 4.5 mm, the diameter of the mouthpiece segment 54 is approximately 6.4 mm to 10 mm. Therefore, when the first capsule 78a is a sphere with a diameter of 3.0 mm to 4.5 mm, the diameter of the mouthpiece segment 54 of the rod 14 is approximately 4.5 mm to 10 mm.

[0077] In addition, it is preferable that the filter material 92 of the third segment 76 of the rod 14 of the heated flavor inhalation system 10 has a suitably low packing density and is soft, for example, because this makes it easier for the user to recognize the capsule 78, which is harder than the filter material 92.

[0078] Generally, the greater the content of the plasticizer contained in the filter material 92, the harder the material becomes. Although the filter material 92 may contain a plasticizer, it is preferable that the filter material 92 covering the first capsule 78a be soft enough to easily recognize the hardness of the first capsule 78a in the rod 14, for example, after several inhalations using the heated flavor inhalation system 10.

[0079] In addition, the inner plug wrapper 94, wrapper 80, and tipping paper 56 of the third segment 76 of the rod 14 of the heated flavor inhalation system 10 are preferably flexible and have a low basis weight, for example, so that the hardness of the first capsule 78a in the rod 14 can be easily recognized.

[0080] As described above, according to this embodiment, a non-combustion heating type flavor inhalation article 14 can be provided that allows a user who has taken at least one inhalation to easily recognize the first capsule 78a when attempting to break the first capsule 78a.

[0081] It should be noted that various modifications of the mouthpiece segment 54 are possible.

[0082] If the second segment 74 is absent, the first segment 72 and the third segment 76 may be disposed adjacent to each other.

[0083] If the first segment 72 and second segment 74 are not present, a third segment 76 is used in connection with the aerosol-generation segment 52. The third segment 76 is preferably made of a paper material rather than cellulose acetate fiber.

[0084] Alternatively, the mouthpiece segment 54 may be formed only from the third segment 76 including the first capsule 78a. The solid rod (filter material) 92 of the third segment 76 may be made of paper.

[0085] The hollow rod 82 of the second segment 74 may be formed from paper.

[0086] Preferably, an adsorbent is disposed in at least one of the hollow rods 82 of the second segment 74 and the solid rods (filter material) 92 of the third segment 76 .

[0087] It is also preferable that the hollow rod 82 of the second segment 74 and the solid rod (filter material) 92 of the third segment 76 are formed as one segment, and that the first capsule 78a is disposed in that one segment.

[0088] As shown in FIG. 2 , the heater 32 and heat transfer unit 30 of the heater 12 can heat the aerosol-generating segment 52 of the rod 14 from the outside. As shown in FIG. 13 , the heater 12 has a heating blade 33 instead of the heater 32 and heat transfer unit 30. The heating blade 33 is disposed in the insertion portion 42. As shown in FIG. 13 , when the user properly inserts the tip 14 a of the rod 14 into the insertion portion 42, the blade 33 is inserted into the internal filler 62 from the tip 14 a side of the aerosol-generating segment 52 of the rod 14. When the blade 33 is heated, it directly heats the filler 62. Thus, the heater 12 can use any suitable heating means as long as it does not burn the aerosol-generating segment 52 of the rod 14. The heater 32 can use Joule heat due to electrical resistance, induction heating (IH), or a chemical reaction such as oxidation heat. In this case, a heat transfer section 30 that is suitable for the heating method is selected.

[0089] The present invention is not limited to the above-described embodiments, and various modifications can be made in the implementation stage without departing from the spirit of the invention. Furthermore, the embodiments may be implemented in appropriate combinations, in which case the combined effects can be obtained. Furthermore, the above-described embodiments include various inventions, and various inventions can be extracted by combining selected elements from the disclosed elements. For example, if the problem can be solved and the desired effect can be obtained even if some elements are deleted from all elements shown in the embodiments, the configuration from which these elements are deleted can be extracted as an invention.
