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

Abstract

This non-combustion heating type flavor inhalation article has an aerosol generating segment and a mouthpiece segment adjacent to the aerosol generating segment. The mouthpiece segment includes a filter material and a breakable capsule, the capsule having a single-layer core-shell structure and being disposed within the filter material. The capsule has a spherical or roughly spherical shape with a diameter of 3.0-4.5 mm. When the capsule is stored for 10 minutes under 45°C and 90% RH conditions, the stress of the capsule within 4 minutes after the storage is 2-6N inclusive at a displacement of 0.5 mm.

Description

[Technical Field]

[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. [Background technology]

[0002] BACKGROUND ART Non-combustion heating type flavor inhalation articles are known which are heated without combustion using an electric heater or the like. It is also known to place a breakable capsule containing a flavoring inside (see, for example, WO 2014 / 171433) inside the filter material of a combustion-type 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 when inhaling before and after the capsule is broken.

[0003] The non-combustion heating type flavor inhalation article differs from combustion type flavor inhalation articles such as cigarettes in that, when a user inhales, - The temperature of the volatilized flavor components that migrate from the aerosol-generating segment to the downstream segment during use (inhalation) is high. -The proportion of water vapor among all volatile components is high. It has been found that these have the following characteristics. 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 inside the filter material of the 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 inside the filter material of the 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 taken at least one inhale attempts to destroy the capsule, the user may mistakenly believe that the capsule is not contained in the filter material due to the softness of the capsule, and may also mistakenly believe that the capsule has been broken in advance. Generally, when a capsule is formed of multiple layers, the cost is more likely to increase than when it is formed of a single layer. Summary of the Invention

[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 allows a user who has taken at least one inhalation to easily recognize the capsule when attempting to break it.

[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.

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0008] As shown in FIG. 1, the non-combustion heating type flavor inhalation system (electrically heated type flavor inhalation system) 10 according to this embodiment is different 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. The battery unit 24 supplies power to, for example, 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 metal material. The metal 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 section 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 section 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, and the like. 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, for example, 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, for example, 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 sheets, which are 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 paper tube made by processing cardboard (200 μm to 500 μm thick) into a cylindrical shape. The cardboard may be made from wood pulp like regular paper, or may be made from cellulose acetate fiber treated with a plasticizer (triacetin) and compressed into a sheet.

[0026] The second segment 74 has 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 mainly 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. It should be noted that the rod 82 may be solid rather than hollow.

[0027] An appropriate plasticizer, such as triacetin, is added to the cellulose acetate fibers of the hollow rod 82 of the second segment 74 in an amount of, for example, 6% to 20% by mass relative to the mass of the cellulose acetate, and the cellulose acetate fibers are hardened. 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 or a different packing density of the cellulose acetate fibers as the hollow rods 82 of the second segment 74. 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 a suitable plasticizer, such as triacetin. The filament denier of the cellulose acetate long fiber plasticized with a plasticizer is preferably 3.0 dpf (denier perfilament) or more and 12.0 dpf or less. The packing density of the cellulose acetate long fiber plasticized with a plasticizer is preferably 130 mg / cc or less. The packing density of the cellulose acetate long fiber plasticized with a plasticizer is preferably 100 mg / cc or more. Setting the packing density of the cellulose acetate long fiber plasticized with a plasticizer within this range makes it easy to fix the capsule 78 in the correct position and also prevents the capsule 78 from popping out when the cutting segment 98, which will be described later, is 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 or plant essential oils. Major flavorings include menthol, tobacco leaf extract, natural plant flavorings (e.g., cinnamon, sage, herbs, chamomile, kudzu, sweet tea, cloves, lavender, cardamom, cloves, 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 suitable fragrances include: cellulose sugar, caramel, cocoa powder, extract, etc.; 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 can 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 of a single layer, and is preferably formed so as to be breakable by an appropriate range of pressing pressure (stress) in an appropriate range of displacement. The method for producing the capsules 78 is not particularly limited. For example, a dripping method can be used to produce capsules 78 with seamless shells. This method uses a double nozzle, simultaneously ejecting the content liquid from the inner nozzle and the liquid coating material from the outer nozzle, allowing the coating liquid to seamlessly envelop the content liquid. The capsules 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. The internal solution may also be ejected using different nozzles. In this case, a triple nozzle may be used to simultaneously eject the internal solution from the inner nozzle, the external solution from the middle nozzle, and the liquid coating material from the outer nozzle, thereby producing capsules 78 with a single shell. Separating the internal and external internal solutions allows the internal solutions with different properties to be ejected at different temperatures and viscosities. For example, the internal internal solution may be a liquid containing a water-soluble flavoring, while the external internal solution may be a liquid containing a fat-soluble flavoring. An emulsifier may also be included in the inner or outer solution.

[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] It is preferable that the capsule 78 of this embodiment is not provided with a water-resistant coating and / or a heat-resistant coating on the outer periphery, for example, so that the capsule 78 can be manufactured inexpensively.

[0037] The capsule 78 may have, for example, a spherical or approximately spherical shape. Here, the term "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 together.

[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 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 mainly made of paper. That is, the outer peripheries of the aerosol-generation segment 52 and the first segment 72, second segment 74, and third segment 76 of the mouthpiece segment 54 are wrapped with the tipping paper 56. Therefore, 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 end 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, equal to or less than 100 μm. 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 this embodiment, the plurality of perforations 58 are arranged in a single row at regular intervals on a circular ring. The plurality of perforations 58 may also be arranged in two rows at regular intervals on two circular rings. 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 conventional cigarette.

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

[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, it is assumed that 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). In this example, 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, and the components in the filler 62 volatilize. In this state, when the user holds the mouth end 14b between their lips and begins to inhale, outside air is drawn into the vapor-containing fluid (mainstream smoke) flowing inside 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 is quickly aerosolized (transformed into minute droplets). When the user inhales, the air and aerosol pass through the fiber-packed layer, and some 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 inhaled. The control unit 34 controls the heater 32 to stop heating when a predetermined time has passed or when the user has inhaled 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 mouth 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 heating-type 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. For example, 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 temperature is higher than the temperature within the filter material near the mouth end of a cigarette, and is more humid 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 1 / 5 to 1 / 3 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] 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 and 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 a capsule 78 is disposed within a 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 a cut segment 98 cut from the rod 14 was pressed toward the central axis of the cut segment 98 to measure the repulsive force of the cut segment 98. The cut segment 98 was formed as a cylindrical body, and the center of the capsule 78 was located on the central axis of the cut segment 98. That is, the cut segment 98 was cylindrical, and the capsule 78, solid rod (filter material) 92, inner plug wrapper 94, wrapper 80, and tipping paper 56 were 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 from each other. 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 constant 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 in the axial direction, the upper surface 104a approaches or moves away from the lower surface 102a. Here, it is assumed that the pressing shaft 106 of the rheometer 100, that is, 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 Fig. 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 in this state the pressing shaft 106 was moved vertically downward to apply a pressing force toward the central axis of the cut-out segment 98. As shown in Fig. 5, a graph was obtained in which the horizontal axis represents the pressing rate and the vertical axis represents the repulsive force. The indentation rate will be briefly explained using Figure 6. The diameter of a sphere such as a capsule or a cylinder (or cylindrical body) such as a cut-out segment 98 in an unloaded state is defined as L1. With the sphere or cylinder supported on the lower surface 102a of the rheometer 100, the pressing shaft 106 connected to the disk body 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, the indentation rate is (L1 - L2) / L1.

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

[0055] When an external force is applied vertically toward the central axis of the cut-out segment 98 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 appropriate 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 Figure 5, an inflection point, designated 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 inflection point α than before inflection point α. This is presumably because, at inflection point α, the tipping paper 56, wrapper 80, inner plug wrapper 94, and filter material 92 of the cut-out segment 98 are in a state equivalent to or close to being fully compressed. If the pushing action of the cut-out segment 98 measured by the rheometer 100 is a pushing action by a user's finger, it is estimated that at the inflection point α, the user will perceive a repulsive force from the capsule 78's shell with their finger or the like. It is estimated that after the inflection point α, the user will feel that they are deforming the capsule 78's shell 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 between the pushing ratios of 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] 5, the repulsive force immediately after the capsule 78 is broken stops at symbol γ, which does not decrease to the repulsive force corresponding to the inflection point α, then starts to increase again and exceeds the repulsive force at the position indicated by 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 about 0.6, then increases again. If the rate of decrease in repulsive force at this time (difference in repulsive force H) is large, it can be said that the sensation of breaking the capsule 78 is easily conveyed to the user. In the experiment to measure the repulsive force of the cut-out segment 98 shown in Figure 4, only the cut-out segment 98 was pressed. This prevents the rod 14 from simultaneously pressing on the segment that was integrated with the cut-out segment 98 before the cut-out segment 98 was cut out. Therefore, in the graph shown in Figure 5, it is possible to eliminate the influence of the material of the segment that was 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. The vicinity of the mouth end of the rod 214 was cut out as a cut-out segment 298 corresponding to the cut-out segment 98 described above. 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 a 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] 7, if a capsule 78 is present within the cut-out segment 298, and the capsule 78 is as soft as or softer than the compressed filter material, the capsule 78 will be compressed together with the tipping paper, wrapper, inner plug wrapper, and filter material and likely to become flattened. 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 if the compression rate increases. In the experiment to measure 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 simultaneously pressing on the segment that was integrated with the cut-out segment 298 before the cut-out segment 298 was cut out. Therefore, in the graph shown in Fig. 8, it is possible to eliminate the influence of the material of the segment that was integrated with the cut-out segment 298.

[0062] Therefore, 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 capsule 78's shell is soft, the inflection point α is less clear. 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, the user 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 FIG. 9 shows an apparatus 110 capable of maintaining an appropriate temperature and humidity within its internal space. In this apparatus 110, a temperature and humidity corresponding to the temperature and humidity when inhaling from the mouth end 14b of the rod 14 using the heated flavor inhalation system 10 according to this embodiment were reproduced, and the capsule 78 was stored therein. Specifically, the temperature inside the apparatus 110 was set to 45°C, the humidity was set to 90% RH, and the capsule 78 was stored therein for 10 minutes. Thereafter, the capsule 78 was subjected to the same measurement as described above using the rheometer 100 described above at room temperature and normal pressure. The measurement was performed so that the capsule 78 was broken and the measurement was completed within 4 minutes after removal from the apparatus 110. The temperature and humidity inside the device 110 are allowed to vary by, for example, a few percent from the target temperature and humidity (for example, 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 the tipping paper 56, wrapper 80, inner plug wrapper 94, and 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 enclosed 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 were destroyed at about 1.5 mm, but the third capsule 78c was destroyed after exceeding 2 mm. A rod 14 including a first capsule 78a, a rod 14 including a second capsule 78b, and a rod 14 including a 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. FIG. 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 "5" for a comfortable fit and a "1" for a poor fit. The test results in Figure 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 less easy to break than the first capsule 78a, but more easy to break than the third capsule 78c. The third capsule 78c was evaluated as being less easy 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 large magnitude of the stress at the time of breakage relative to the displacement shown in Fig. 10. It is presumed that the greater the magnitude of the 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 larger and more abrupt the change in stress value, the better the feeling perceived by the user when capsule 78 is broken. Additionally, the first capsule 78a experiences a higher stress against initial displacement than the second capsule 78b and the third capsule 78c. Therefore, it is expected that a user will perceive the first capsule 78a as being appropriately hard. That is, when the first capsule 78a is placed within the mouthpiece segment 54 of the rod 14, it is expected that a user will be able to easily recognize the inflection point at point α shown in FIG. 5 compared to when the second capsule 78b and the third capsule 78c are used. 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 able to be 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 comfortable to break than the first capsule 78a, but more comfortable to break 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. For this reason, when the second capsule 78b is used, it is expected that the difference in slope before the inflection point α and after the inflection point α shown in Fig. 5 will be smaller than when the first capsule 78a is used. This is expected to make it more difficult for the user to recognize that they are pressing the second capsule 78b than when the first capsule 78a is used, resulting in a delayed recognition. Furthermore, when the second capsule 78b is used, the stress at the time of breaking is lower than when the first capsule 78a is used, and it is assumed that the difference in height H between points β and γ shown in Fig. 5 is smaller. This is presumably 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 comfortable to break than the second capsule 78b and the third capsule 78c. As shown in Fig. 11, the third capsule 78c is smaller and softer than the first capsule 78a at an initial displacement of up to 1 mm. For this reason, when the third capsule 78c is used, it is expected that the difference in slope before the inflection point α and after the inflection point α shown in Fig. 5 will be smaller than that of the first capsule 78a. As a result, it is expected that the user will be slower to recognize that they are pressing the third capsule 78c than when the first capsule 78a is used. Furthermore, when the third capsule 78c is used, the stress at the time of breaking is lower than when the first capsule 78a is used, and it is assumed that the difference in height H between points β and γ shown in Fig. 5 is smaller. This is presumably why the breakability of the third capsule 78c in the rod 14 was rated lower than the breakability of the first capsule 78a in the rod 14. Furthermore, the displacement of the third capsule 78c from the start of deformation to its breakage was larger than that of the first capsule 78a and the second capsule 78b. 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 78c 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 realizing that he or she was pressing the third capsule 78c. Therefore, it is assumed that the third capsule 78c broke without raising the user's expectations about breaking the third capsule 78c. Therefore, it is assumed 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 began to deform until it broke was too large. For this reason, it is presumed that the third capsule 78c broke at a displacement that exceeded the range of displacement that the user expected from when the user realized that they were pressing the third capsule 78c with their finger, teeth, etc. until it broke, and that the user expected less. Therefore, it is presumed that the user gave a poor evaluation of the feeling of breaking the third capsule 78c (including the rod 14). It is also assumed that the time from when the third capsule 78c began to deform until it broke was too long. For this reason, it is assumed that the third capsule 78c broke during a time period from when the user realized that they were pressing the third capsule 78c with their fingers, teeth, etc. until it broke, which exceeded the range of time when the user's expectations were high, and therefore when the user's expectations were low. Therefore, it is assumed that the user gave a poor evaluation of the feel 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 a first capsule 78a according to this embodiment is disposed within a third segment 76 with a heater 12. That is, when the capsule 78 is stored for 10 minutes under conditions of 45°C and 90% RH, it is preferable that the capsule 78 stored within 4 minutes be a first capsule 78a having 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 capsule 78 be a first capsule 78a having 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 be 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 inhalation to easily recognize the first capsule 78a when attempting to break the first capsule 78a. Furthermore, when the capsules 78 are stored for 10 minutes under conditions of 45°C and 90% RH, it is preferable that the capsules 78 stored within 4 minutes be first capsules 78a, whose stress at a displacement of 1 mm is greater than that of the second capsules 78b and the third capsules 78c, and whose stress at a displacement of 1 mm is greater than that of the second capsules 78b and the third capsules 78c, and whose stress at a displacement of 20 N is greater than that of the third capsules 78b and 78c, which is the greatest repulsive force available under current manufacturing technology. The displacement at a displacement of 1 mm for the first capsules 78a is more preferably greater than or equal to 4 N and less than or equal to 20 N. It is preferable that the first capsules 78a be formed so that they break with a displacement of 1 mm or more and 2 mm or less, so that the user feels that the stroke of the user's finger or teeth after recognizing them is neither too small nor too large. These features also provide a rod 14, i.e., a non-combustion heating 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] When stored for 10 minutes under conditions of 45°C and 90% RH, the stress within 4 minutes after storage is 2 N to 6 N when the displacement is 0.5 mm, and the stress within 4 minutes after storage is 3 N to 20 N when the displacement is 1 mm. The shell of the first capsule 78a 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 an appropriate recipe so that when stored for 10 minutes under conditions of 45°C and 90% RH, the stress within 4 minutes after storage is 2 N to 6 N when the displacement is 0.5 mm, and the stress within 4 minutes after storage is 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 (gellan gum:starch) in the coating 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 first capsule 78a can have a relatively light shell weight, i.e., a hard shell can be used 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 appropriately larger than approximately 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 the first capsule 78a breaks, 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 is 70% or less. If 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. If 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, if 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 will be 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 an appropriately low filling 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 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 puffs 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 on 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 the first capsule 78a is disposed in that one segment.

[0088] As shown in FIG. 2, the heater 32 and heat transfer section 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 section 30. The heating blade 33 is disposed in the insertion section 42. As shown in FIG. 13, when the user properly inserts the tip 14a of the rod 14 into the insertion section 42, the blade 33 is inserted into the filler 62 inside the tip 14a of the aerosol-generating segment 52 of the rod 14. When the blade 33 is heated, it directly heats the filler 62. In this way, any appropriate heating means can be used for the heater 12 as long as it does not burn the aerosol-generating segment 52 of the rod 14. The heating method of the heater 32 may be an induction heating (IH) method or a method using a chemical reaction such as oxidation heat, in addition to using Joule heat due to electrical resistance. In this case, a heat transfer section 30 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.
