Description

非燃焼加熱型香味吸引器具Non-combustion heating type flavor suction device
　本発明はたばこロッド、冷却セグメント、およびマウスピースを備える非燃焼加熱型香味吸引器具に関する。 The present invention relates to a non-combustion heating type flavor suction device including a tobacco rod, a cooling segment, and a mouthpiece.
　近年、非燃焼加熱型香味吸引器具をデバイスに挿入して使用する製品が市販されている（例えば特許文献１）。これらの非燃焼加熱型香味吸引器具は、デバイスへの挿入のしやすさや、十分な香喫味の送達の観点から、ある一定以上の太さが望まれる。しかし、非燃焼加熱型香味吸引器具の直径が大きくなると当該器具に与えられる熱量が増え、かつ唇と接触する面積も大きくなる。この結果、吸口端近傍の温度が上昇し、ユーザーが、使用時に吸口端近傍の温度を不快に感じるおそれがあった。 In recent years, a product in which a non-combustion heating type flavor suction device is inserted into a device and used is commercially available (for example, Patent Document 1). These non-combustion heating type flavor suction devices are desired to have a certain thickness or more from the viewpoint of ease of insertion into the device and delivery of sufficient flavor and taste. However, as the diameter of the non-combustion heating type flavor suction device increases, the amount of heat given to the device increases and the area in contact with the lips also increases. As a result, the temperature near the mouthpiece end rises, and the user may feel uncomfortable with the temperature near the mouthpiece end during use.

Is. The upper limit thereof is usually 800 mg / cm 3 or less, preferably 600 mg / cm 3 or less.
（２）冷却セグメント
　冷却セグメントは、たばこロッド１で発生した香喫味成分や蒸気を冷却する等してエアロゾル化を促進するための部材である。冷却セグメント３は中空の紙管であってよい。紙管はラッパーやチップペーパよりも剛性の高いカードボードで構成されることが好ましい。当該紙管には、ベンチレーションＶ（開孔）を設けてもよい。ベンチレーションは紙管の円周に沿って複数設けられることが好ましい。冷却セグメントの吸口側端部から加熱端に向かって、ベンチレーションが設けられる位置の上限は、エアロゾル化の促進や冷却の観点から、冷却セグメントの吸口側端部から４ｍｍ以内の範囲が好ましく、２ｍｍ以内の範囲がさらに好ましい。また、ベンチレーションが設けられる位置の下限は、製品全体の耐久性の観点から、冷却セグメントの吸口側端部から０．５ｍｍ以上が好ましく１．０ｍｍ以上がさらに好ましい。すなわち、一態様において、ベンチレーションは冷却セグメントの吸口側端部から上流に向かって０．５～４ｍｍの範囲に設けられ、別態様において１．０～２ｍｍの範囲に設けられる。作業効率の観点から、ベンチレーションは、完成した非燃焼加熱型香味吸引器具にレーザー加工を施して設けることが好ましい。また冷却セグメント３内には、熱交換効率を高めるためにギャザー付けされたシートを充填してもよい。冷却セグメント３の寸法は限定されないが、長さは１５～２５ｍｍであることが好ましく、直径は５．５～７．５ｍｍであることが好ましい。 (2) Cooling segment The cooling segment is a member for promoting aerosolization by cooling the flavor components and steam generated in the tobacco rod 1. The cooling segment 3 may be a hollow paper tube. The paper tube is preferably composed of a card board having a higher rigidity than a wrapper or chip paper. Ventilation V (opening) may be provided in the paper tube. It is preferable that a plurality of ventilations are provided along the circumference of the paper tube. From the viewpoint of promoting aerosolization and cooling, the upper limit of the position where ventilation is provided from the mouthpiece side end of the cooling segment to the heating end is preferably within 4 mm from the mouthpiece side end of the cooling segment, and is preferably 2 mm. The range within is more preferable. Further, the lower limit of the position where the ventilation is provided is preferably 0.5 mm or more, more preferably 1.0 mm or more from the mouthpiece side end of the cooling segment from the viewpoint of durability of the entire product. That is, in one embodiment, the ventilation is provided in the range of 0.5 to 4 mm upstream from the mouthpiece side end of the cooling segment, and in another embodiment, it is provided in the range of 1.0 to 2 mm. From the viewpoint of work efficiency, it is preferable that the ventilation is provided by laser processing the completed non-combustion heating type flavor suction device. Further, the cooling segment 3 may be filled with a gathered sheet in order to increase the heat exchange efficiency. The dimensions of the cooling segment 3 are not limited, but the length is preferably 15 to 25 mm, and the diameter is preferably 5.5 to 7.5 mm.
　前述のとおり、ベンチレーションは冷却セグメントの外周面の周方向に配置されることが好ましい。その周方向の配置の数は、限定されず２つ以上であればよい。孔径は１００～１０００μｍであることが好ましく、３００～８００μｍであることがより好ましい。開孔形状は略円形または略楕円形であることが好ましい。略楕円形の場合、長径が孔径に相当する。 As described above, the ventilation is preferably arranged in the circumferential direction of the outer peripheral surface of the cooling segment. The number of arrangements in the circumferential direction is not limited and may be two or more. The pore diameter is preferably 100 to 1000 μm, more preferably 300 to 800 μm. The opening shape is preferably substantially circular or substantially elliptical. In the case of a substantially elliptical shape, the major axis corresponds to the hole diameter.
　冷却セグメント３はたばこロッド１に比べて剛性が低い場合が多い。このような異なる剛性を持つパーツをチップペーパで接続する場合、剛性が高いパーツの直径を剛性が低いパーツの直径よりも小さくすると不良が発生しにくい。したがって、たばこロッド１に比べて冷却セグメント３の剛性が高い場合は、その直径をたばこロッド１の直径より小さくすることが好ましい。例えば、たばこロッドの直径が７ｍｍである場合、冷却セグメント、マウスピースの直径は好ましくは６．９ｍｍである。 The cooling segment 3 is often less rigid than the tobacco rod 1. When connecting parts having such different rigidity with chip paper, if the diameter of the part having high rigidity is made smaller than the diameter of the part having low rigidity, defects are less likely to occur. Therefore, when the rigidity of the cooling segment 3 is higher than that of the tobacco rod 1, it is preferable that the diameter thereof is smaller than the diameter of the tobacco rod 1. For example, when the diameter of the tobacco rod is 7 mm, the diameter of the cooling segment and the mouthpiece is preferably 6.9 mm.
（３）マウスピース
　マウスピースは吸口端を構成する部材である。本発明においてマウスピース５は、吸口端方向に向かってフィルタ５２とセンターホールフィルター５４をこの順に備える。 (3) Mouthpiece The mouthpiece is a member that constitutes the mouthpiece end. In the present invention, the mouthpiece 5 includes a filter 52 and a center hole filter 54 in this order toward the mouthpiece end direction.
（３－１）フィルタ
　フィルタ５２としてはアセテートフィルターやペーパーフィルター等の公知の中実なフィルタ部材を使用できる。ペーパーフィルターとは、紙をクレープローラ等で加工して皺を付けこれをプラグ巻取紙で巻上げて調製される、紙が充填されたフィルタである。アセテートフィルターとはセルロースアセテート繊維が充填されたフィルタである。アセテートフィルターを構成する繊維の単繊度は、好ましくは５～１２（デニール／フィラメント）であり、より好ましくは５～８（デニール／フィラメント）である。当該繊維の総繊度は、好ましくは１２，０００～３５，０００（デニール／トータル）であり、より好ましくは２０，０００～３０，０００（デニール／トータル）である。非燃焼加熱型香味吸引器具においては、エアロゾル生成量が通常の燃焼型香味吸引器具と比較して少ないため、フィルタによる濾過は少ないことが好ましい。単繊度が大きいと濾過率は低下するが、一方でアセテートフィルターの製造が困難となる。一方、総繊度が小さいと濾過率は下がるが、総繊度が小さすぎると繊維充填密度が過度に低下してアセテートフィルターの硬さが低下する。これらの観点から、前記単繊度と総繊度を前記数値範囲にすることで濾過率が低く、かつ使用に適したアセテートフィルターを得ることができる。前記繊維の断面形状は限定されないが、Ｒ形状またはＹ形状が好ましく、コストの観点からはＹ形状がより好ましい。また、フィルタ硬さを高めるために、可塑剤としてトリアセチンを用いることもできる。トリアセチンの添加量は、トウ重量に対して５～１０重量％であることが好ましい。 (3-1) Filter As the filter 52, a known solid filter member such as an acetate filter or a paper filter can be used. The paper filter is a paper-filled filter prepared by processing paper with a crepe roller or the like to form wrinkles and winding it with a plug-winding paper. The acetate filter is a filter filled with cellulose acetate fibers. The single fineness of the fibers constituting the acetate filter is preferably 5 to 12 (denier / filament), and more preferably 5 to 8 (denier / filament). The total fineness of the fiber is preferably 12,000 to 35,000 (denier / total), more preferably 20,000 to 30,000 (denier / total). In the non-combustion heating type flavor suction device, since the amount of aerosol produced is smaller than that of the normal combustion type flavor suction device, it is preferable that the filtration by the filter is small. If the single fineness is large, the filtration rate decreases, but on the other hand, it becomes difficult to manufacture an acetate filter. On the other hand, if the total fineness is small, the filtration rate is lowered, but if the total fineness is too small, the fiber packing density is excessively lowered and the hardness of the acetate filter is lowered. From these viewpoints, by setting the single fineness and the total fineness within the above numerical ranges, an acetate filter having a low filtration rate and suitable for use can be obtained. The cross-sectional shape of the fiber is not limited, but an R shape or a Y shape is preferable, and a Y shape is more preferable from the viewpoint of cost. In addition, triacetin can also be used as a plasticizer in order to increase the hardness of the filter. The amount of triacetin added is preferably 5 to 10% by weight based on the tow weight.
（３－２）センターホールフィルター
　センターホールフィルター５４としては、例えばフィルタの中央部に空間を設けたものを使用できる。この場合、穴径はフィルタ直径の２０～７０％であることが好ましく、２０～４０％であることがさらに好ましい。具体的に穴径は、好ましくは１．０～５．０ｍｍである。その好ましい下限値は、１．２ｍｍ以上または１．５ｍｍ以上であり、その好ましい上限値は、４．５ｍｍ以下、３．０ｍｍ以下、または２．５ｍｍ以下である。フィルタの肉厚（壁部の厚み）は、好ましくは１～３ｍｍ、より好ましくは２～３ｍｍである。穴径が下限値以下である穴の成形は困難であり、内壁に毛羽立ちが生じてしまいエアロゾルが補足され、デリバリー効率が低下することがある。また穴径が下限値以下である穴を形成するマンドレルの耐久性に問題が生じ、マンドレルが製造中に振動して穴がうねる等の穴の形状が不安定となる。また穴径が条件値を超えると、フィルタ硬さが担保できずに咥え心地が低下し、さらには肉厚が薄くなるので唾液等で濡れた場合に耐久性が低下するおそれもある。一態様において、センターホールフィルターとして、７ｍｍ直径のフィルタに径４．５ｍｍの穴を設けたものが挙げられる。また、穴の断面積は、好ましくは０．７～２０ｍｍ２であり、より好ましくは１．６～１６ｍｍ２である。また、別態様として複数の穴孔を有するセンターホールフィルターを使用してもよい。この場合、複数の穴は例えば円周方向に沿って等間隔に配置されてもよい。複数の穴の合計の断面積は、好ましくは０．７～２０ｍｍ２であり、より好ましくは１．６～１６ｍｍ２である。 (3-2) Center Hall Filter As the center hole filter 54, for example, one having a space provided in the center of the filter can be used. In this case, the hole diameter is preferably 20 to 70%, more preferably 20 to 40% of the filter diameter. Specifically, the hole diameter is preferably 1.0 to 5.0 mm. The preferable lower limit value is 1.2 mm or more or 1.5 mm or more, and the preferable upper limit value is 4.5 mm or less, 3.0 mm or less, or 2.5 mm or less. The wall thickness (thickness of the wall portion) of the filter is preferably 1 to 3 mm, more preferably 2 to 3 mm. It is difficult to form a hole having a hole diameter of less than or equal to the lower limit value, and fluffing may occur on the inner wall to supplement the aerosol and reduce the delivery efficiency. In addition, there is a problem in the durability of the mandrel that forms a hole whose hole diameter is not more than the lower limit, and the shape of the hole becomes unstable, such as the mandrel vibrating during manufacturing and the hole undulates. Further, if the hole diameter exceeds the condition value, the hardness of the filter cannot be guaranteed and the gripping comfort is lowered, and further, the wall thickness is thinned, so that the durability may be lowered when wet with saliva or the like. In one aspect, as the center hole filter, a filter having a diameter of 7 mm and a hole having a diameter of 4.5 mm can be mentioned. The cross-sectional area of the hole is preferably 0.7 to 20 mm 2 , more preferably 1.6 to 16 mm 2 . Alternatively, a center hole filter having a plurality of holes may be used. In this case, the plurality of holes may be arranged at equal intervals along the circumferential direction, for example. The total cross-sectional area of the plurality of holes is preferably 0.7 to 20 mm 2 , more preferably 1.6 to 16 mm 2 .
　フィルタ５２とセンターホールフィルター５４の長さはそれぞれ非燃焼加熱型香味吸引器具１０の全長に対し、９～１６％程度であることが好ましい。一態様においてフィルタ５２とセンターホールフィルター５４のそれぞれの長さは５～９ｍｍ程度である。 The length of the filter 52 and the center hole filter 54 is preferably about 9 to 16% with respect to the total length of the non-combustion heating type flavor suction device 10, respectively. In one aspect, the length of each of the filter 52 and the center hole filter 54 is about 5 to 9 mm.
　フィルタ５２とセンターホールフィルター５４のそれぞれがフィルターラッパー（フィルターインナーラッパー）によって巻装され、それらがフィルタ成型紙（フィルターアウターラッパー）によって接続されていてもよい。マウスピース５の直径は限定されないが、冷却セグメント３と同じであることが好ましい。 Each of the filter 52 and the center hole filter 54 may be wound by a filter wrapper (filter inner wrapper), and they may be connected by a filter molding paper (filter outer wrapper). The diameter of the mouthpiece 5 is not limited, but is preferably the same as that of the cooling segment 3.
　センターホールフィルター５４はある一定の硬さを有することが好ましい。センターホールフィルター５４が変形しにくく、ユーザーの唇との接触面積が小さくなるので、ユーザーが不快な温度を感じにくくなるからである。本発明における硬さは、特表２０１６－５２３５６５号公報明細書段落００１０～００１４に開示されているとおり、部材が変形するときの抵抗を意味する。たばこロッドの側面に負荷をかける前と後での直径の変化から硬さを求めることができる。具体的に、硬さは以下のようにして測定される。
１）センターホールフィルターを、その長手方向が水平となるようにして基板の上に載置し、その高さＤｓを測定する。
２）加圧治具を用いて前記センターホールフィルター側面を加圧して圧縮する。
　　加圧：３００ｇ、加圧時間：１０秒、加圧治具ヘッド径：φ１２ｍｍ
３）加圧後の前記センターホールフィルターの高さＤｄを測定する
４）硬さＨ（％）を下記式より算出する。
　　Ｈ（％）＝Ｄｄ／Ｄｓ×１００ The center hole filter 54 preferably has a certain hardness. This is because the center hole filter 54 is less likely to be deformed and the contact area with the user's lips is smaller, so that the user is less likely to feel an unpleasant temperature. The hardness in the present invention means resistance when a member is deformed, as disclosed in paragraphs 0010 to 0014 of Japanese Patent Application Laid-Open No. 2016-523565. Hardness can be determined from the change in diameter before and after applying a load to the side surface of the tobacco rod. Specifically, the hardness is measured as follows.
1) Place the center hole filter on the substrate so that its longitudinal direction is horizontal, and measure its height Ds.
2) The side surface of the center hole filter is pressurized and compressed using a pressurizing jig.
Pressurization: 300 g, pressurization time: 10 seconds, pressurization jig head diameter: φ12 mm
3) Measure the height Dd of the center hole filter after pressurization. 4) Calculate the hardness H (%) from the following formula.
H (%) = Dd / Ds × 100
　センターホールフィルター５４の硬さは、好ましくは９０％以上、より好ましくは９３％以上、さらに好ましくは９５％以上である。その上限は限定されないが、９９％以下または９８％以下程度である。 The hardness of the center hole filter 54 is preferably 90% or more, more preferably 93% or more, and further preferably 95% or more. The upper limit is not limited, but is about 99% or less or 98% or less.
　センターホールフィルターを構成する繊維の単繊度は、好ましくは５～１２（デニール／フィラメント）であり、より好ましくは５～８（デニール／フィラメント）である。また、当該繊維の総繊度は、好ましくは３０，０００～６０，０００（デニール／トータル）であり、より好ましくは３５，０００～４５，０００（デニール／トータル）である。繊維の断面形状は好ましくはＲ形状またはＹ形状であり、コスト面からはＹ形状がより好ましい。非燃焼加熱型香味吸引器具においては、エアロゾル生成量が通常の燃焼型香味吸引器具と比較して少ないため、センターホールフィルターにおけるエアロゾルのロスは少ないことが好ましい。センターホールフィルターの壁部（ニク部）の繊維の充填密度が低すぎると、当該部分でエアロゾルが濾過されてしまう。したがって、センターホールフィルターは高速製造が可能である範囲で壁部のトウ充填密度がある程度高いことが好ましい。前記単繊度と総繊度を前記数値範囲にすることで濾過率が低く、かつ使用に適したセンターホールフィルターを得ることができる。また、フィルタ硬さを高めるために、可塑剤としてトリアセチンを用いることもできる。トリアセチンの添加量は、トウ重量に対して１０～２０重量％であることが好ましい。 The single fineness of the fibers constituting the center hole filter is preferably 5 to 12 (denier / filament), and more preferably 5 to 8 (denier / filament). The total fineness of the fiber is preferably 30,000 to 60,000 (denier / total), and more preferably 35,000 to 45,000 (denier / total). The cross-sectional shape of the fiber is preferably R shape or Y shape, and the Y shape is more preferable from the viewpoint of cost. In the non-combustion heating type flavor suction device, the amount of aerosol produced is smaller than that in the normal combustion type flavor suction device, so that it is preferable that the aerosol loss in the center hole filter is small. If the fiber filling density of the wall portion (nik portion) of the center hole filter is too low, the aerosol will be filtered at that portion. Therefore, it is preferable that the toe filling density of the wall portion of the center hole filter is high to some extent within the range where high-speed manufacturing is possible. By setting the single fineness and the total fineness within the above numerical ranges, a center hole filter having a low filtration rate and suitable for use can be obtained. In addition, triacetin can also be used as a plasticizer in order to increase the hardness of the filter. The amount of triacetin added is preferably 10 to 20% by weight based on the tow weight.
（４）チップペーパ
　チップペーパ７は、たばこロッド１、冷却セグメント３、マウスピース５のうち２つ以上を接続するために用いる紙をいう。一方、ラッパーは、たばこロッド１、冷却セグメント３、またはマウスピース５を構成する個々の部材を巻装するための紙をいう。 (4) Chip Paper The chip paper 7 refers to paper used for connecting two or more of the tobacco rod 1, the cooling segment 3, and the mouthpiece 5. On the other hand, the wrapper refers to a paper for winding individual members constituting the tobacco rod 1, the cooling segment 3, or the mouthpiece 5.
　チップペーパおよびラッパーに用いられる原紙は、限定されず、セルロース繊維を用いたものを挙げることができる。そのようなセルロース繊維としては、植物由来のもの、化学合成されたもののいずれを用いてもよく、これらの混合物であってもよい。植物由来の繊維としては、亜麻繊維や木材繊維、種子繊維等のパルプが挙げられ、漂白していない有色の未晒パルプとしてもよいが、白く清潔感のある外観とするために、酸化剤、還元剤等の漂白剤を用いて漂白した晒パルプの使用が好ましい。 The base paper used for the chip paper and the wrapper is not limited, and examples thereof include those using cellulose fibers. As such a cellulose fiber, either a plant-derived fiber or a chemically synthesized fiber may be used, or a mixture thereof may be used. Examples of plant-derived fibers include pulps such as flax fiber, wood fiber, and seed fiber, which may be unbleached colored unbleached pulp. It is preferable to use bleached pulp bleached with a bleaching agent such as a reducing agent.
　通常のシガレット用の巻紙の場合、巻紙の自然燃焼速度に影響を及ぼし得る通常の燃焼調節剤（助燃剤等）としてクエン酸アルカリ金属塩等が使用される。本発明では加熱型香味吸引器具品とするため、ラッパーは燃焼調節剤を含まなくてもよい。また、通常のシガレットと異なり、前述のとおり本発明のたばこ充填材にはエアロゾル発生源が含まれうる。この場合、チップペーパとして耐油性、耐水性巻紙を用いることが好ましい。 In the case of ordinary cigarette wrapping paper, citric acid alkali metal salt or the like is used as an ordinary combustion regulator (combustion agent, etc.) that can affect the natural combustion speed of the wrapping paper. In the present invention, since it is a heated flavor suction device, the wrapper does not have to contain a combustion regulator. Further, unlike ordinary cigarettes, the tobacco filler of the present invention may contain an aerosol generation source as described above. In this case, it is preferable to use oil-resistant and water-resistant wrapping paper as the chip paper.
　ラッパーの坪量の下限は、好ましくは３０ｇ／ｍ２以上であり、より好ましくは３５ｇ／ｍ２以上であり、さらに好ましくは４０ｇ／ｍ２以上である。上限は、好ましくは６５ｇ／ｍ２以下、より好ましくは５０ｇ／ｍ２以下である。また、チップペーパの坪量の下限は、好ましくは２０ｇ／ｍ２以上であり、より好ましくは２５ｇ／ｍ２以上であり、さらに好ましくは３０ｇ／ｍ２以上である。上限は、好ましくは５０ｇ／ｍ２以下、より好ましくは４５ｇ／ｍ２以下、さらに好ましくは４０ｇ／ｍ２以下である。坪量は、ＪＩＳ　Ｐ８１２４に規定される方法で測定することができる。 The lower limit of the basis weight of the wrapper is preferably 30 g / m 2 or more, more preferably 35 g / m 2 or more, and further preferably 40 g / m 2 or more. The upper limit is preferably 65 g / m 2 or less, more preferably 50 g / m 2 or less. The lower limit of the basis weight of the chip paper is preferably 20 g / m 2 or more, more preferably 25 g / m 2 or more, and further preferably 30 g / m 2 or more. The upper limit is preferably 50 g / m 2 or less, more preferably 45 g / m 2 or less, still more preferably 40 g / m 2 or less. Basis weight can be measured by the method specified in JIS P8124.
　本発明の非燃焼加熱型香味吸引器具は、発明の効果を損なわない範囲で、上記以外の部材を備えていてもよい。このような部材としては、支持部材等が挙げられる。これらの部材は任意の位置に配置されてよいが、吸口端部には配置されないことが好ましい。また、本発明の非燃焼加熱型香味吸引器具はたばこロッドの上流側、すなわち香味吸引器具の先端部に、炭素熱源を備えていてもよい。この態様においては、たばこロッドは炭素熱源によって加熱される。しかしながら、本発明の非燃焼加熱型香味吸引器具は、炭素熱源加熱方式に比べて加熱温度がより高温になる電気加熱方式のシステムに特に有用である。 The non-combustion heating type flavor suction device of the present invention may include members other than the above as long as the effects of the present invention are not impaired. Examples of such a member include a support member and the like. These members may be arranged at arbitrary positions, but are preferably not arranged at the mouthpiece end. Further, the non-combustion heating type flavor suction device of the present invention may be provided with a carbon heat source on the upstream side of the tobacco rod, that is, at the tip of the flavor suction device. In this embodiment, the tobacco rod is heated by a carbon heat source. However, the non-combustion heating type flavor suction device of the present invention is particularly useful for an electric heating system in which the heating temperature becomes higher than that of the carbon heat source heating system.
　本発明の非燃焼加熱型香味吸引器具は、ユーザーが使用時（吸引時）に吸口端近傍の温度を不快に感じない。この理由は限定されないが次のように推察される。本発明の非燃焼加熱型香味吸引器具は、マウスピースとして吸口端方向にフィルタ５２とセンターホールフィルター５４をこの順に備える。エアロゾルはまずフィルタ５２に導入される。フィルタ５２からセンターホール５４に導入される際、通気抵抗が低下し、かつ流路が急に狭くなる。この際、エアロゾルは流速が上昇しセンターホールフィルター５４に滞留する時間が短くなる。このため、ユーザーは不快な高い温度を感じにくくなると考えられる。 The non-combustion heating type flavor suction device of the present invention does not make the user feel uncomfortable with the temperature near the mouthpiece end during use (during suction). The reason for this is not limited, but it can be inferred as follows. The non-combustion heating type flavor suction device of the present invention includes a filter 52 and a center hole filter 54 in this order as a mouthpiece in the direction of the mouthpiece end. The aerosol is first introduced into the filter 52. When introduced from the filter 52 into the center hole 54, the ventilation resistance decreases and the flow path suddenly narrows. At this time, the flow velocity of the aerosol increases and the time of staying in the center hole filter 54 becomes shorter. Therefore, it is considered that the user is less likely to feel an unpleasant high temperature.

　本発明の非燃焼加熱型香味吸引器具の製造方法は限定されないが、たばこロッド１、マウスピース５をそれぞれ準備して、たばこロッド１とマウスピース５の間に冷却セグメント３を形成するようにして、これらをチップペーパ７で巻装して製造できる。あるいは、本発明の非燃焼加熱型香味吸引器具は、たばこロッド１と、冷却セグメント３としての紙管と、マウスピース５をそれぞれ準備して、これら３つの部材をチップペーパ７で巻装して製造できる。 2.
