　従来、材料の燃焼をすることなく、エアロゾル源を含んだ香味源を有する香味発生物品を加熱することで、香味を含むエアロゾルを吸引する加熱式たばこが知られている。このような加熱式たばこでは、吸引の際、加熱によって発現する揮発性化合物の冷却不足により、十分なエアロゾル化が行われないことがある。 Conventionally, heat-not-burn cigarettes have been known in which flavor-containing aerosols are inhaled by heating flavor-generating articles having flavor sources containing aerosol sources without burning materials. With such a heated cigarette, sufficient aerosolization may not be achieved due to insufficient cooling of volatile compounds generated by heating during inhalation.
　そこで、十分なエアロゾル化を行うために、エアロゾル形成基材の下流側にポリ乳酸等のシートから形成されたエアロゾル冷却要素を配置したり、中空管の管壁を貫通して形成された穴を備えた冷却セグメントを配置したりすることが知られている（例えば、特許文献１、２参照）。 Therefore, in order to achieve sufficient aerosolization, an aerosol cooling element formed of a sheet of polylactic acid or the like is arranged downstream of the aerosol-forming substrate, or a hole is formed through the tube wall of the hollow tube. It is known to arrange cooling segments with

　しかしながら、エアロゾル形成基材の下流側にポリ乳酸等のシートから形成されたエアロゾル冷却要素を配置する場合には、食品衛生上使用できる素材が限定される上、部材が増えることによりコストが上昇したり、製造工程が増えたりするという問題がある。また、エアロゾル形成基材の下流側に中空管の管壁を貫通して形成された穴を備えた冷却セグメントを配置する場合には、中空管に穴を形成する必要があるので、コストが上昇したり、製造工程が増えたりするという問題がある。 However, when an aerosol cooling element formed of a sheet of polylactic acid or the like is arranged downstream of the aerosol-forming substrate, the materials that can be used for food hygiene are limited, and the cost increases due to the increase in the number of members. There is also a problem that the number of manufacturing processes increases. Also, if a cooling segment with a hole formed through the wall of the hollow tube is arranged downstream of the aerosol-forming substrate, it is necessary to form the hole in the hollow tube, which reduces the cost. However, there are problems such as an increase in the manufacturing process and an increase in the number of manufacturing processes.

Therefore, sufficient aerosolization can be performed while suppressing an increase in cost and an increase in manufacturing processes.
　また、冷却部材の長さを２８ｍｍ以上とすることで、揮発性化合物を十分に冷却することができるので、エアロゾル化、すなわち粒子化が促進され、大きな粒子径を得ることができる。 In addition, by setting the length of the cooling member to 28 mm or more, the volatile compound can be sufficiently cooled, so aerosolization, that is, particle formation is promoted, and a large particle size can be obtained.

The filter part 40 can be manufactured by a known method. For example, when synthetic fibers such as cellulose acetate tow are used as the material of the filter part 40, a polymer solution containing a polymer and a solvent is spun and crimped. It can be manufactured by a method. As the method, for example, the method described in International Publication No. 2013/067511 can be used.

Alternatively, a paper filter filled with sheet-like pulp paper may be used instead of the acetate filter.

　フィルタ部４０の少なくとも一部には、活性炭が添加されてもよい。活性炭の添加量は、１本の香味発生物品１００において、活性炭の比表面積×活性炭の重量／フィルタ部４０の通気方向に対して垂直方向の断面積の値として、１５．０ｍ２／ｃｍ２以上、８０．０ｍ２／ｃｍ２以下である。上記の「活性炭の比表面積×活性炭の重量／フィルタ部４０の通気方向に対して垂直方向の断面積」を、便宜上、「単位断面積当たりの活性炭の表面積」と表現することがある。この単位断面積当たりの活性炭の表面積は、１本の香味発生物品１００が有するフィルタ部４０に添加する活性炭の比表面積と、添加した活性炭の重量、フィルタ部４０の断面積、に基づき算出できる。なお、活性炭はそれが添加されるフィルタ部４０中には均一に分散されていないこともあり、フィルタ部４０の全ての断面（通気方向に対して垂直方向の断面）において、上記の範囲を満たすことを要求するものではない。単位断面積当たりの活性炭の表面積が上記の範囲内であることで、加熱により生成する成分を所望の量でユーザにデリバリできるとともに、ユーザに対して所望の香味感を与えることができる。単位断面積当たりの活性炭の表面積が上記範囲の下限より小さいと、活性炭を添加することによる効果を十分に得ることができない。一方で、単位断面積当たりの活性炭の表面積が上記範囲の上限より大きいと、加熱により生成する成分が必要以上に低減してしまう。 Activated carbon may be added to at least part of the filter unit 40 . The amount of activated carbon to be added is 15.0 m 2 /cm 2 or more in one flavor-generating article 100 as a value of specific surface area of activated carbon×weight of activated carbon/cross-sectional area of filter part 40 in a direction perpendicular to the ventilation direction. , 80.0 m 2 /cm 2 or less. For convenience, the above "specific surface area of activated carbon×weight of activated carbon/cross-sectional area of filter section 40 perpendicular to ventilation direction" may be expressed as "surface area of activated carbon per unit cross-sectional area". The surface area of activated carbon per unit cross-sectional area can be calculated based on the specific surface area of activated carbon added to the filter portion 40 of one flavor-generating article 100, the weight of the added activated carbon, and the cross-sectional area of the filter portion 40. Since the activated carbon is not uniformly dispersed in the filter part 40 to which it is added, the above range is satisfied in all cross sections of the filter part 40 (cross sections perpendicular to the ventilation direction). does not require that When the surface area of the activated carbon per unit cross-sectional area is within the above range, the component generated by heating can be delivered to the user in the desired amount, and the desired flavor can be imparted to the user. If the surface area of the activated carbon per unit cross-sectional area is less than the lower limit of the above range, the effect of adding activated carbon cannot be sufficiently obtained. On the other hand, if the surface area of the activated carbon per unit cross-sectional area is larger than the upper limit of the above range, the components generated by heating will be reduced more than necessary.
　単位断面積当たりの活性炭の表面積は、１７．０ｍ２／ｃｍ２以上であることがより好ましく、３５．０ｍ２／ｃｍ２以上であることがさらに好ましい。一方、７７．０ｍ２／ｃｍ２以下であることがより好ましく、７３．０ｍ２／ｃｍ２以下であることがさらに好ましい。単位断面積当たりの活性炭の表面積は、例えば、活性炭の比表面積とその添加量、フィルタ部４０の通気方向に垂直な方向の断面積を調整することで調整できる。上記の単位断面積当たりの活性炭の表面積の算出は、活性炭が添加されているフィルタ部４０を基準として算出される。フィルタ部４０が複数のセグメントから構成されている場合、活性炭が添加されているセグメントのみの断面積、長さを基準とする。 The surface area of the activated carbon per unit cross-sectional area is more preferably 17.0 m 2 /cm 2 or more, more preferably 35.0 m 2 /cm 2 or more. On the other hand, it is more preferably 77.0 m 2 /cm 2 or less, even more preferably 73.0 m 2 /cm 2 or less. The surface area of activated carbon per unit cross-sectional area can be adjusted, for example, by adjusting the specific surface area of activated carbon, the added amount thereof, and the cross-sectional area of the filter portion 40 in the direction perpendicular to the ventilation direction. The above calculation of the surface area of activated carbon per unit cross-sectional area is based on the filter portion 40 to which activated carbon is added. When the filter part 40 is composed of a plurality of segments, the cross-sectional area and length of only the segment to which activated carbon is added are used as references.

When the filter part 40 consists of a single segment, the segment to which activated carbon is added becomes the filter part 40 as it is. On the other hand, when it is composed of a plurality of segments, it is preferable that the segment added with activated carbon be arranged upstream of the segment that constitutes the mouthpiece end. On the other hand, activated carbon may be added to the segment forming the mouthpiece end. When the filter portion 40 is a multi-segment filter, the length of the filter portion 40, which is the reference for the amount of activated carbon added, is the length of the segment to which activated carbon is added. The amount of activated carbon to be added may be, for example, 4.0 mg or more and 24.0 mg or less, preferably 4.5 mg or more and 23.0 mg or less, and 10.5 mg or more, in terms of the weight of the entire filter part 40. , 22.0 mg or less.

The spacer portion 20 is arranged in contact with the tobacco rod portion 10 between the tobacco rod portion 10 and the paper tube 30 . Similar to the filter portion 40, the spacer portion 20 can be made of synthetic fibers such as cellulose acetate tow. The spacer portion 20 positions the tobacco rod portion 10 toward the upstream side 101 of the flavor generating article 100 so that the tobacco rod portion 10 can contact the heater. Specifically, the spacer portion 20 prevents the tobacco rod portion 10 from being pushed toward the downstream side 102 of the flavor generating article 100, that is, toward the paper tube 30 when the heater is inserted into the tobacco rod portion 10. . Also, the spacer portion 20 separates the paper tube 30 from the tobacco rod portion 10 .
　また、スペーサ部２０の中央には、たばこロッド部１０から放出された揮発性化合物の濾過を避けつつ、たばこロッド部１０を支えるための、たばこロッド部１０の長手方向に貫通する開口２１が設けられている。開口２１の形状は、どのような形状であってもよく、円、四角、三角、またはプロペラ型等様々な形状を採用できる。また、たばこロッド部１０の中央に貫通孔を設けることに代えて、たばこロッド部１０の側面に、たばこロッド部１０の長手方向に貫通する溝を設けてもよい。 Further, in the center of the spacer portion 20, there is provided an opening 21 penetrating in the longitudinal direction of the tobacco rod portion 10 for supporting the tobacco rod portion 10 while avoiding filtration of volatile compounds released from the tobacco rod portion 10. It is The shape of the opening 21 may be any shape, and various shapes such as a circle, a square, a triangle, or a propeller shape can be adopted. Further, instead of providing a through-hole in the center of the tobacco rod portion 10 , grooves extending through the tobacco rod portion 10 in the longitudinal direction may be provided in the side surfaces of the tobacco rod portion 10 .
　（ペーパチューブ３０について）
　ペーパチューブ３０は、スペーサ部２０とフィルタ部４０とに隣接して挟持され得る。ペーパチューブ３０は、通常、円筒等の周方向の断面が中空（空洞）となるキャビティが設けられた棒状または筒状の部材を含む。 (Regarding the paper tube 30)
The paper tube 30 can be sandwiched adjacent to the spacer section 20 and the filter section 40 . The paper tube 30 usually includes a rod-shaped or cylindrical member such as a cylinder provided with a cavity having a hollow (hollow) circumferential cross-section.
　ペーパチューブ３０の長軸方向の長さは、製品のサイズに合わせて適宜変更し得るが、２８ｍｍ以上であることが好ましく、４３ｍｍ以上であることがより好ましく、また、７１ｍｍ以下であることが好ましい。ペーパチューブ３０の長軸方向の長さを上記下限以上とすることで、十分な冷却効果を確保して良好な香味を得ることができ、上記上限以下とすることで、揮発性化合物およびエアロゾルがペーパチューブ３０の内壁に付着することによりロスを抑制することができる。 The length of the paper tube 30 in the longitudinal direction can be appropriately changed according to the size of the product, but is preferably 28 mm or more, more preferably 43 mm or more, and preferably 71 mm or less. . By setting the length of the paper tube 30 in the long axis direction to the above lower limit or more, a sufficient cooling effect can be secured and a good flavor can be obtained. Loss can be suppressed by adhering to the inner wall of the paper tube 30 .
　ペーパチューブ３０の全表面積は、特段制限されず、例えば、３００ｍｍ２／ｍｍ以上、１０００ｍｍ２／ｍｍ以下を挙げることができる。この表面積は、ペーパチューブ３０の通気方向の長さ（ｍｍ）当たりの表面積である。ペーパチューブ３０の全表面積は、４００ｍｍ２／ｍｍ以上であることが好ましく、４５０ｍｍ２／ｍｍ以上であることがより好ましく、一方、６００ｍｍ２／ｍｍ以下であることが好ましく、５５０ｍｍ２／ｍｍ以下であることがより好ましい。ペーパチューブ３０は、その内部構造が大きい全表面積を有することが望ましい。ペーパチューブ３０の構成材料の厚みは、特段制限されず、例えば、５μｍ以上、５００μｍ以下であってよく、また、１０μｍ以上、２５０μｍ以下であってよい。 The total surface area of the paper tube 30 is not particularly limited, and may be, for example, 300 mm 2 /mm or more and 1000 mm 2 /mm or less. This surface area is the surface area per length (mm) of the paper tube 30 in the ventilation direction. The total surface area of the paper tube 30 is preferably 400 mm 2 /mm or more, more preferably 450 mm 2 /mm or more, and preferably 600 mm 2 /mm or less, and preferably 550 mm 2 /mm or less. It is more preferable to have The paper tube 30 desirably has a large total surface area in its internal structure. The thickness of the constituent material of the paper tube 30 is not particularly limited, and may be, for example, 5 μm or more and 500 μm or less, or 10 μm or more and 250 μm or less.
　なお、ペーパチューブ３０は、特許文献１に記載されたポリ乳酸等により形成された冷却用のシート（冷却材）を用いておらず、また、引用文献２に記載されたペーパチューブ３０を貫通してペーパチューブ３０の周方向に形成された開孔を有していない。これにより、これらの構成を採用した場合におけるコストの上昇や製造工程の増加を抑制することができる。また、ペーパチューブ３０の周方向に開孔を形成した場合には、開孔から流入する空気により揮発性化合物を冷却することができるが、外気が取り込まれる分味が薄くなり、喫味が低下するという問題があるが、本実施形態ではそのようなことは起こらない。 Note that the paper tube 30 does not use the cooling sheet (coolant) formed of polylactic acid or the like described in Patent Document 1, and the paper tube 30 described in Cited Document 2 is not penetrated. It does not have an aperture formed in the circumferential direction of the paper tube 30 . As a result, it is possible to suppress an increase in cost and an increase in the number of manufacturing processes when these configurations are employed. In addition, when the paper tube 30 is formed with holes in the circumferential direction, the volatile compounds can be cooled by the air flowing in from the holes, but the outside air is taken in, and the taste becomes weaker, resulting in a lower smoking taste. However, in this embodiment, such a problem does not occur.

With such a water content, the occurrence of winding stains is suppressed, and the winding suitability of the tobacco rod portion 10 at the time of manufacture is improved. In addition, the flavor-generating article 100 is easily deformed appropriately according to the cross-sectional shape of the holding portion. There are no particular restrictions on the size of the chopped tobacco contained in the first tobacco filling and the preparation method thereof. For example, dried tobacco leaves may be chopped into widths of 0.5 mm or more and 2.0 mm or less, preferably 0.8 mm or more and 1.2 mm or less.

The above first tobacco filling is wrapped with wrapping paper so that it is on the inside to form the tobacco rod portion 10 .
　第２のたばこ充填物は、被充填物に充填されたたばこシートから構成される。たばこシートの枚数は、１枚であってもよく、２枚以上であってもよい。第２のたばこ充填物が１枚のたばこシートから構成される場合の態様としては、例えば、その一辺が被充填物の長手方向と同程度の長さを有するたばこシートが、被充填物の長手方向と水平に複数回折り返された状態で充填される態様（いわゆるギャザーシート）が挙げられる。また、その一辺が被充填物の長手方向と同程度の長さを有するたばこシートが、被充填物の長手方向と直交する方向に巻き回された状態で充填される態様も挙げられる。 The second tobacco filling is composed of tobacco sheets filled in the filling material. The number of tobacco sheets may be one, or two or more. As a mode in which the second tobacco filling is composed of one tobacco sheet, for example, a tobacco sheet having one side having a length approximately equal to the longitudinal direction of the item to be filled is arranged in the longitudinal direction of the item to be filled. A mode (so-called gathered sheet) in which the sheet is filled in a state in which the sheet is folded back multiple times horizontally to the direction is exemplified. In addition, there is also a mode in which a tobacco sheet having a side length approximately equal to the longitudinal direction of the object to be filled is wound in a direction orthogonal to the longitudinal direction of the object to be filled.
　第２のたばこ充填物が、２枚以上のたばこシートから構成される場合の態様としては、例えば、その一辺が被充填物の長手方向と同程度の長さを有する複数のたばこシートが、同心状に配置されるように、被充填物の長手方向と直交する方向に巻き回された状態で充填される態様が挙げられる。「同心状に配置される」とは、すべてのたばこシートの中心が略同じ位置にあるように配置されていることをいう。また、たばこシートの枚数は、特に制限されないが、２枚、３枚、４枚、５枚、６枚、または７枚である態様を挙げることができる。２枚以上のたばこシートはすべて同じ組成あるいは物性であってもよいし、各たばこシートの中の一部または全部が異なる組成あるいは物性であってもよい。また、各たばこシートの厚みは、それぞれが同一であってもよく、異なっていてもよい。 As a mode in which the second tobacco filling is composed of two or more tobacco sheets, for example, a plurality of tobacco sheets each having a length approximately equal to the longitudinal direction of the material to be filled are arranged concentrically. A mode in which the material is wound in a direction orthogonal to the longitudinal direction of the material to be filled so as to be arranged in the shape of a shape is exemplified. "Concentrically arranged" means that the centers of all the tobacco sheets are arranged at approximately the same position. In addition, the number of tobacco sheets is not particularly limited, but may be 2, 3, 4, 5, 6, or 7 sheets. Two or more tobacco sheets may all have the same composition or physical properties, or a part or all of each tobacco sheet may have different compositions or physical properties. Moreover, the thickness of each tobacco sheet may be the same or different.
　第２のたばこ充填物は、幅の異なる複数のたばこシートを準備して、底部から頂部に向かって幅が小さくなるように積層した積層体を調製し、これを巻管に通して巻き上げ成形することで製造できる。この製造方法によれば、該複数のたばこシートが、長手方向に延在するとともに、該長手方向軸を中心として同心状に配置されるようになる。また、該長手方向軸と、最内層のたばこシートとの間に、長手方向に延在する嵌合部が形成されてもよい。 For the second tobacco filling, a plurality of tobacco sheets with different widths are prepared to prepare a laminated body so that the width decreases from the bottom to the top, and the laminated body is passed through a winding tube and rolled up. can be manufactured by According to this manufacturing method, the plurality of tobacco sheets extend in the longitudinal direction and are arranged concentrically about the longitudinal axis. Also, a fitting portion extending in the longitudinal direction may be formed between the longitudinal axis and the innermost tobacco sheet.
　この製造方法において、積層体は巻上げ成形後に隣接する上記たばこシート間に非接触部が形成されるように調製されることが好ましい。複数のたばこシート間に、当該たばこシートが接触しない非接触部（隙間）が存在すると、香味流路を確保して香味成分のデリバリー効率を高めることができる。他方で、複数のたばこシートの接触部分を介してヒータからの熱を外側のたばこシートに伝達できるので高い伝熱効率を確保することができる。複数のたばこシート間に、当該たばこシートが接触しない非接触部を設けるために、例えば、エンボス加工したたばこシートを用いる、隣接するたばこシート同士の全面を接着せずに積層する、隣接するたばこシート同士の一部を接着して積層する、あるいは隣接するたばこシート同士の全面あるいは一部を、巻上げ成形後に剥がれるように軽度に接着して積層することで積層体を調製する方法を挙げることができる。巻紙を含めたたばこロッド部１０を調製する場合には、積層体の最底部に上記の巻紙を配置してもよい。また、積層体の最頂部にマンドレル等の筒状ダミーを載置して第２のたばこ充填物を形成した後に、当該ダミーを除去することで、嵌合部を形成することもできる。 In this manufacturing method, the laminate is preferably prepared so that a non-contact portion is formed between the adjacent tobacco sheets after roll-forming. If there is a non-contact portion (gap) between the plurality of tobacco sheets that the tobacco sheets do not come into contact with, it is possible to ensure the flavor flow path and improve the delivery efficiency of the flavor component.

　（香味発生物品１００の使用態様について）
　図２は、図１に示した香味発生物品１００の使用の態様を示す模式図である。図２では、香味発生物品１００を香味吸引器２００に適用した喫煙システムを示す。図２に示すように、香味発生物品１００は、ユーザが使用する際、香味吸引器２００に挿入される。香味吸引器２００は、香味発生物品１００が挿入されるチャンバ２１０を有する。また、チャンバ２１０の底面中央部には、ヒータ（加熱要素）２２０が設けられており、ヒータ２２０は、先端が尖っているピン状、またはブレード状の形状を有する。ヒータ２２０は、香味発生物品１００のたばこロッド部１０内に挿入され、たばこロッド部１０を加熱する。 (Usage Mode of Flavor-Generating Article 100)
FIG. 2 is a schematic diagram showing how the flavor-generating article 100 shown in FIG. 1 is used. FIG. 2 shows a smoking system in which the flavor generating article 100 is applied to a flavor inhaler 200. As shown in FIG. As shown in FIG. 2, the flavor generating article 100 is inserted into a flavor inhaler 200 when used by a user. Flavor inhaler 200 has a chamber 210 into which flavor generating article 100 is inserted. A heater (heating element) 220 is provided at the center of the bottom surface of the chamber 210, and the heater 220 has a pin-like or blade-like shape with a sharp tip. The heater 220 is inserted into the tobacco rod portion 10 of the flavor generating article 100 to heat the tobacco rod portion 10 .
　ヒータ２２０は、香味吸引器２００内に設けられた図示しない電源から供給される電力によって例えば２００℃以上まで発熱する。このヒータ２２０の熱によってたばこロッド部１０が加熱されることにより、香味を含む揮発性化合物が放出される。放出された揮発性化合物は、スペーサ部２０を通ってペーパチューブ３０に移送され、ペーパチューブ３０で冷却されてエアロゾル化され、ユーザーがマウスピースから吸い込むことで、香味がユーザの口腔内に届くことになる。 The heater 220 generates heat up to, for example, 200° C. or higher by power supplied from a power source (not shown) provided in the flavor inhaler 200 . The heat of the heater 220 heats the tobacco rod portion 10, thereby releasing flavor-containing volatile compounds. The released volatile compound is transferred to the paper tube 30 through the spacer part 20, cooled in the paper tube 30 and aerosolized, and when the user inhales from the mouthpiece, the flavor reaches the user's oral cavity. become.
　ここで、香味発生物品１００を香味吸引器２００のチャンバ２１０に挿入した際に、チャンバ２１０に挿入されているペーパチューブ３０の長さは、５ｍｍであることが好ましい。すなわち、チャンバ２１０から露出するペーパチューブ３０の長さは、ペーパチューブの全長が例えば２８ｍｍである場合に２３ｍｍとなり、例えば４３ｍｍである場合に３８ｍｍとなる。このように香味発生物品１００および香味吸引器２００を設計することで、ペーパチューブ３０における揮発性化合物の冷却効果を向上させ、エアロゾル化を促進することができる。 Here, when the flavor generating article 100 is inserted into the chamber 210 of the flavor inhaler 200, the length of the paper tube 30 inserted into the chamber 210 is preferably 5 mm. That is, the length of the paper tube 30 exposed from the chamber 210 is 23 mm when the total length of the paper tube is 28 mm, and 38 mm when the total length of the paper tube is 43 mm. By designing the flavor generating article 100 and the flavor inhaler 200 in this manner, the cooling effect of the volatile compounds in the paper tube 30 can be improved and aerosolization can be promoted.
　（エアロゾル温度について）
　上述した香味発生物品１００を含む複数の香味発生物品について、ペーパチューブ３０における冷却効果を確認すべく実験を行った。具体的には、上述した香味発生物品１００において、ペーパチューブ３０の長さのみを２０ｍｍ、２８ｍｍ、４３ｍｍ、５７ｍｍ、７１ｍｍと変化させたサンプルを準備し、ペーパチューブ３０出口部におけるエアロゾル温度を測定した。なお、たばこロッド部１０の長さは１２ｍｍ、スペーサ部２０の長さは８ｍｍ、フィルタ部４０の長さは７ｍｍとした。 (About aerosol temperature)
An experiment was conducted to confirm the cooling effect of the paper tube 30 on a plurality of flavor generating articles including the flavor generating article 100 described above. Specifically, in the flavor generating article 100 described above, samples were prepared by changing only the length of the paper tube 30 to 20 mm, 28 mm, 43 mm, 57 mm, and 71 mm, and the aerosol temperature at the outlet of the paper tube 30 was measured. . The length of the tobacco rod portion 10 was 12 mm, the length of the spacer portion 20 was 8 mm, and the length of the filter portion 40 was 7 mm.
　このとき、上述したように、チャンバ２１０に挿入されているペーパチューブ３０の長さを５ｍｍとすると、チャンバ２１０から露出するペーパチューブ３０の長さは、それぞれのサンプルについて、１５ｍｍ、２３ｍｍ、３８ｍｍ、５２ｍｍ、６６ｍｍとなる。 At this time, as described above, if the length of the paper tube 30 inserted into the chamber 210 is 5 mm, the length of the paper tube 30 exposed from the chamber 210 is 15 mm, 23 mm, 38 mm, 52 mm and 66 mm.
　温度測定の箇所は、フィルタ部４０の下流側１０２から９ｍｍ内側とし、ペーパチューブ３０出口部におけるエアロゾル温度を測定すべく、熱電対をペーパチューブ３０の内部に３ｍｍ程度挿入した。また、熱電対は、坂口電熱社のＴ３５１０１を用いた。 The temperature measurement point was 9 mm inside from the downstream side 102 of the filter part 40, and a thermocouple was inserted into the paper tube 30 by about 3 mm to measure the aerosol temperature at the outlet part of the paper tube 30. The thermocouple used was T35101 manufactured by Sakaguchi Electric Heat Co., Ltd.
　また、温度測定にあたり、ＣＡＭＢＵＳＴＩＯＮ社のＤＭＳ５００ＭＫIIを用いて香味発生物品１００を吸引した。ＤＭＳ５００ＭＫIIにより、５５ｍｌ／２ｓｅｃ（２秒間で５５ｍｌの吸引動作を行う）で１回吸引（パフ）したときの最大温度を、エアロゾル温度として測定した。なお、室温は、２５℃であった。 Also, in measuring the temperature, the flavor generating article 100 was sucked using DMS500MKII manufactured by CAMBUSTION. With DMS500MKII, the maximum temperature when aspirating (puffing) once at 55 ml/2 sec (aspirating 55 ml in 2 seconds) was measured as the aerosol temperature. The room temperature was 25°C.
　図３は、本発明の一実施形態に係るエアロゾル温度の測定結果を示すグラフである。横軸は、ペーパチューブ３０の長さ（ｍｍ）を示し、縦軸は、温度（℃）を示している。なお、この温度は、１パフ目の温度を示している。図３に示すように、ペーパチューブ３０の長さを２０ｍｍ以上とすることで、エアロゾル温度が６０℃以下に低下していることが分かる。そのため、上述した冷却用のシートやペーパチューブ３０の周方向に形成された開孔を用いることなく、コストの上昇や製造工程の増加を抑制した上で、十分なエアロゾル化を行うことができる。 FIG. 3 is a graph showing measurement results of aerosol temperature according to one embodiment of the present invention. The horizontal axis indicates the length (mm) of the paper tube 30, and the vertical axis indicates the temperature (°C). This temperature indicates the temperature of the first puff. As shown in FIG. 3, it can be seen that the aerosol temperature is lowered to 60° C. or less by setting the length of the paper tube 30 to 20 mm or more. Therefore, without using the above-described cooling sheet or the openings formed in the circumferential direction of the paper tube 30, it is possible to suppress the increase in cost and the number of manufacturing processes and perform sufficient aerosolization.
　また、ペーパチューブ３０の長さが４３ｍｍ以上である場合には、ペーパチューブ３０の長さが２０ｍｍである場合よりも、１０℃以上エアロゾル温度が低下していることが分かる。そのため、ペーパチューブ３０の長さを４３ｍｍ以上とすることで、エアロゾル温度をより十分に低下させることができる。 Also, it can be seen that when the length of the paper tube 30 is 43 mm or more, the aerosol temperature is lower by 10°C or more than when the length of the paper tube 30 is 20 mm. Therefore, by setting the length of the paper tube 30 to 43 mm or longer, the aerosol temperature can be sufficiently lowered.
　（エアロゾルの粒子径について）
　次に、上述した香味発生物品１００を含む複数の香味発生物品について、ペーパチューブ３０における粒子径を確認すべく実験を行った。具体的には、上述した香味発生物品１００において、ペーパチューブ３０の長さのみを２０ｍｍ、２８ｍｍ、４３ｍｍ、５７ｍｍ、７１ｍｍと変化させたサンプルを準備し、ペーパチューブ３０内におけるエアロゾルの粒子径を測定した。 (Regarding aerosol particle size)
Next, an experiment was conducted to confirm the particle size in the paper tube 30 for a plurality of flavor generating articles including the flavor generating article 100 described above. Specifically, in the flavor generating article 100 described above, samples were prepared by changing only the length of the paper tube 30 to 20 mm, 28 mm, 43 mm, 57 mm, and 71 mm, and the particle diameter of the aerosol in the paper tube 30 was measured. bottom.
　粒子径の測定は、ＣＡＭＢＵＳＴＩＯＮ社のＤＭＳ５００ＭＫIIを用いた。ＤＭＳ５００ＭＫIIにより、５５ｍｌ／２ｓｅｃ（２秒間で５５ｍｌの吸引動作を行う）で１回パフし、装置内に吸引されたエアロゾルの粒子径を測定した。なお、室温は、２５℃であった。 DMS500MKII from CAMBUSTION was used to measure the particle size. DMS500MKII was used to puff once at 55 ml/2 sec (55 ml was sucked in 2 seconds), and the particle size of the aerosol sucked into the device was measured. The room temperature was 25°C.
　図４は、本発明の一実施形態に係る粒子径の測定結果を示すグラフである。横軸はパフ回数を示し、縦軸は粒子径（ｎｍ）を示している。図４に示すように、ペーパチューブ３０の長さを２８ｍｍ以上とすることで、特に３パフ目以降の粒子径が大きくなっている（７０ｎｍ程度）ことが分かる。すなわち、一般的な燃焼型の紙巻きたばこにおけるエアロゾルの粒子径が１００ｎｍを超えることを考慮すると、一般的な燃焼型の紙巻きたばこに近い粒子径が実現されていることが分かる。これは、ペーパチューブ３０の長さを２８ｍｍ以上とすることで、揮発性化合物が十分に冷却され、エアロゾル化、すなわち粒子化が促進され、粒子径が成長したものと考えられる。 FIG. 4 is a graph showing the measurement results of particle size according to one embodiment of the present invention. The horizontal axis indicates the number of puffs, and the vertical axis indicates the particle diameter (nm). As shown in FIG. 4, it can be seen that by setting the length of the paper tube 30 to 28 mm or longer, the particle diameter is particularly large (about 70 nm) after the third puff. That is, considering that the particle size of the aerosol in general combustible cigarettes exceeds 100 nm, it can be seen that a particle diameter close to that of general combustible cigarettes is achieved. This is probably because the paper tube 30 having a length of 28 mm or longer sufficiently cooled the volatile compound, promoted aerosolization, ie, particle formation, and increased the particle size.
　（ペーパチューブ３０の長さについて）
　なお、上述した説明では、香味発生物品１００の定まった長さを有するが、香味発生物品１００は、長さが可変、特にペーパチューブ３０の長さが可変であってもよい。 (Regarding the length of the paper tube 30)
In the above description, the flavor-generating article 100 has a fixed length, but the length of the flavor-generating article 100 may be variable, particularly the length of the paper tube 30 may be variable.
　図５は、本発明の一実施形態に係る香味発生物品１００Ａを示す別の概略側断面図である。図６は、図５に示した第１部材１１０と第２部材１２０とを組み合わせた状態を示す模式図である。図５および図６に示すように、香味発生物品１００Ａは、図１に示したたばこロッド部１０、スペーサ部２０およびペーパチューブ３０の一部を有する第１部材１１０と、図１に示したペーパチューブ３０の一部およびフィルタ部４０を有する第２部材１２０とを含む。 FIG. 5 is another schematic side sectional view showing the flavor generating article 100A according to one embodiment of the present invention. FIG. 6 is a schematic diagram showing a state in which the first member 110 and the second member 120 shown in FIG. 5 are combined. As shown in FIGS. 5 and 6, the flavor generating article 100A includes a first member 110 having a portion of the tobacco rod portion 10, the spacer portion 20 and the paper tube 30 shown in FIG. A second member 120 having a portion of the tube 30 and a filter portion 40 is included.
　ここで、第２部材１２０が、第１部材１１０に挿入されることで香味発生物品１００Ａが形成される。また、第１部材１１０の下流側１０２の端部には、内側に折り返された折り返し部６０が形成され、第２部材の１２０の上流側１０１の端部には、外側に折り返された折り返し部７０が形成される。 Here, the second member 120 is inserted into the first member 110 to form the flavor generating article 100A. A folded portion 60 that is folded back inward is formed at the end portion of the downstream side 102 of the first member 110, and a folded portion that is folded back outward is formed at the end portion of the upstream side 101 of the second member 120. 70 is formed.
　折り返し部６０は、たばこロッド部１０、スペーサ部２０およびペーパチューブ３０の一部をチップペーパ５０で巻装した後、チップペーパ５０の下流側１０２の端部をペーパチューブ３０の内側に折り込んで形成される。折り返し部７０は、ペーパチューブ３０の一部およびフィルタ部４０を、あらかじめ折りを付けたチップペーパ５０で巻装することで形成される。このとき、折り返し部７０が外側に広がるように、折りに切り込みを入れておくことが好ましい。 The folded portion 60 is formed by wrapping the tobacco rod portion 10 , the spacer portion 20 and part of the paper tube 30 with the tipping paper 50 and then folding the downstream end 102 of the tipping paper 50 inside the paper tube 30 . be done. The folded portion 70 is formed by wrapping a portion of the paper tube 30 and the filter portion 40 with tip paper 50 that has been folded in advance. At this time, it is preferable to cut the fold so that the folded portion 70 spreads outward.
　折り返し部６０と折り返し部７０とは、第２部材１２０が第１部材１１０に挿入された後、第２部材１２０を第１部材１１０から引き抜こうとしたとき互いに係合することで、第２部材１２０が第１部材１１０から抜けることを防止することができる。 After the second member 120 is inserted into the first member 110, the folded portion 60 and the folded portion 70 are engaged with each other when the second member 120 is pulled out from the first member 110, thereby can be prevented from coming out of the first member 110 .
　また、香味発生物品１００Ａのペーパチューブ３０の最短長さは、第２部材１２０の上流側１０１の端部が、第１部材１１０のスペーサ部２０に当接したときの長さであり、香味発生物品１００Ａのペーパチューブ３０最長長さは、折り返し部６０と折り返し部７０とが互いに係合したときの長さである。 The shortest length of the paper tube 30 of the flavor-generating article 100A is the length when the end portion of the upstream side 101 of the second member 120 contacts the spacer portion 20 of the first member 110. The longest length of the paper tube 30 of the article 100A is the length when the folded portion 60 and the folded portion 70 are engaged with each other.
　そこで、ペーパチューブ３０の最短長さが２８ｍｍとなるように香味発生物品１００Ａを構成することにより、上述したように、たばこロッド部１０から放出された揮発性化合物を十分に冷却するとともに、大きな粒子径を得ることができる。また、ペーパチューブ３０の長さが可変であることにより、ユーザがペーパチューブ３０の長さを変化させることで、ユーザ自身が香味発生物品の喫味を変化させることができる。 Therefore, by configuring the flavor generating article 100A so that the shortest length of the paper tube 30 is 28 mm, as described above, the volatile compounds released from the tobacco rod portion 10 are sufficiently cooled, and large particles diameter can be obtained. In addition, since the length of the paper tube 30 is variable, the user himself/herself can change the taste of the flavor-generating article by changing the length of the paper tube 30 .
　以上、本発明のいくつかの実施形態について説明してきたが、上記した発明の実施形態は、本発明の理解を容易にするためのものであり、本発明を限定するものではない。本発明は、その趣旨を逸脱することなく、変更、改良され得るとともに、本発明にはその均等物が含まれる。また、上述した課題の少なくとも一部を解決できる範囲、または、効果の少なくとも一部を奏する範囲において、特許請求の範囲および明細書に記載された各構成要素の組み合わせ、または、省略が可能である。 Although several embodiments of the present invention have been described above, the above-described embodiments of the present invention are intended to facilitate understanding of the present invention, and do not limit the present invention. The present invention may be modified and improved without departing from its spirit, and the present invention includes equivalents thereof. In addition, within the range where at least part of the above problems can be solved or where at least part of the effect is achieved, the components described in the claims and the specification can be combined or omitted. .
