　本発明の一側面に係るたばこ製品用のフィルタは、たばこ製品の長手方向に連設された内部構造の異なるセグメントを複数含む。紙部材で被覆された空洞を含み、香料を内包する香料カプセルを当該空洞に保持する香料セグメントと、当該香料セグメントよりも刻側に設けられ、フィルタの横断面のほぼ中心に沿って通気孔が設けられた第１の環状セグメントと、香料セグメントよりも吸口側に設けられ、フィルタの横断面のほぼ中心に沿って、香料カプセルの直径よりも内径の小さい通気孔が設けられた第２の環状セグメントとを含み、第１の環状セグメント及び第２の環状セグメントは、香料を担持した状態において、フィルタの径方向の押圧により通気孔を塞ぐことができるとともに所定の復元力を有する。 The filter for tobacco products according to one aspect of the present invention includes a plurality of segments having different internal structures connected in the longitudinal direction of the tobacco product. A perfume segment including a cavity covered with a paper member and holding a perfume capsule containing the perfume in the cavity, and a vent hole provided substantially along the center of the cross section of the filter. A first annular segment provided, and a second annular provided on the suction side of the fragrance segment, and provided with a vent hole having an inner diameter smaller than the diameter of the fragrance capsule along substantially the center of the cross section of the filter. The first annular segment and the second annular segment including the segment can close the vent hole by pressing in the radial direction of the filter and have a predetermined restoring force in a state where the fragrance is carried.
　このようにすれば、使用者が指でフィルタの一部である環状セグメントを押圧したり解放したりすることによって、通気孔を塞いだり開いたりすることができる。そして、環状セグメントには香料が担持されるため、使用者の操作によって、香味の強弱を双方向的に切り替えることができる。すなわち、単純な構成でありながら香味強度の切り替えを実現することができる。 In this way, the user can close or open the vent hole by pressing or releasing the annular segment that is a part of the filter with a finger. And since a fragrance | flavor is carry | supported by an annular segment, the strength of a flavor can be switched bidirectionally by a user's operation. That is, the flavor intensity can be switched with a simple configuration.
　また、第１の環状セグメント及び第２の環状セグメントは、押圧の解放から３０秒後に通気孔の断面積が０．３ｍｍ２以上に復元するようにしてもよい。特に、押圧の解放から３０秒後に通気孔の断面積が０．３ｍｍ２以上に復元すれば、使用者が通常の喫煙において香味強度の変更を楽しむのに十分なものとなる。すなわち、３０秒以内に、通気孔の断面積が０．３ｍｍ２以上に復元していれば、使用者は次回のパフ（吸引）において香味強度の変更を十分に感じられる。  Moreover, you may make it the 1st annular segment and the 2nd annular segment restore | restore the cross-sectional area of a vent hole to 0.3 mm < 2 > or more 30 seconds after release of a press. In particular, if the cross-sectional area of the vent hole is restored to 0.3 mm 2 or more after 30 seconds from the release of the pressure, it is sufficient for the user to enjoy the change of flavor intensity in normal smoking. That is, if the cross-sectional area of the vent hole is restored to 0.3 mm 2 or more within 30 seconds, the user can sufficiently feel the change in flavor intensity at the next puff (suction).
　また、第１の環状セグメント及び第２の環状セグメントの通気孔は直径が２．０ｍｍ以上、且つ６．０ｍｍ以下とし、第１の環状セグメント及び第２の環状セグメントのフィルタの長手方向の長さの合計は１５．０ｍｍ以上、且つ３２．０ｍｍ以下としてもよい。具体的にこのような構成によれば、香味強度の切り替えを十分に感じることができるものとなる。 The vent holes of the first annular segment and the second annular segment have a diameter of 2.0 mm or more and 6.0 mm or less, and the longitudinal lengths of the filters of the first annular segment and the second annular segment. May be 15.0 mm or more and 32.0 mm or less. Specifically, according to such a configuration, the change of flavor intensity can be sufficiently felt.
　また、第１の環状セグメント、第２の環状セグメント及び香料セグメントは、外周を撥油性又は撥水性を有する紙部材で被覆されるようにしてもよい。このようにすれば、香料がたばこ製品の外周に滲み出すことを抑制できる。また、撥油性又は撥水性を有する紙部材によれば、一般的に、従来の巻紙に用いられる紙部材を用いるよりもフィルタ部の強度を向上させることができる。 Further, the outer circumference of the first annular segment, the second annular segment, and the fragrance segment may be covered with a paper member having oil repellency or water repellency. If it does in this way, it can suppress that a fragrance | flavor oozes out to the outer periphery of a tobacco product. Further, according to the paper member having oil repellency or water repellency, generally, the strength of the filter portion can be improved as compared with the use of the paper member used for the conventional wrapping paper.
　フィルタは、通気孔が設けられていないフィルタセグメントを、最も刻側にさらに含むようにしてもよい。このようにすれば、タールやニコチンの吸着、煙の冷却といった効果が得られるとともに、刻を含むたばこロッドをフィルタに連設した場合、香料成分が刻に移ってしまうことを抑制できる。また、貫通孔のない通常のフィルタセグメントを設けることによりたばこ刻の吸口側への通気孔を通じた移動を規制することができる。さらに、当該フィルタセグメントの周囲に巻かれる巻紙やチップペーパーに換気孔（貫通孔）を設け、フィルタ全体での通気抵抗を調整するようにしてもよい。上記の第１の環状セグメント、第２の環状セグメント及び香料セグメントのように内部に空洞のある箇所の場合、換気孔を設けても全体の通気抵抗を調整するのは困難であるところ、上記のフィルタセグメントの場合は通気抵抗の調整に好適なものとなる。 The filter may further include a filter segment not provided with a vent hole on the most etched side. If it does in this way, while the effect of adsorption | suction of tar and nicotine, cooling of smoke will be acquired, when the tobacco rod containing an engraving is connected with a filter, it can control that a fragrance ingredient shifts to an engraving. Further, by providing a normal filter segment having no through-hole, movement of the tobacco through the ventilation hole to the suction side can be restricted. Furthermore, a ventilation hole (through hole) may be provided in the wrapping paper or chip paper wound around the filter segment so as to adjust the ventilation resistance in the entire filter. In the case where there is a cavity inside such as the first annular segment, the second annular segment, and the fragrance segment, it is difficult to adjust the overall ventilation resistance even if a ventilation hole is provided. In the case of a filter segment, it is suitable for adjusting the ventilation resistance.
　香料はメンソールであり、当該メンソールの添加量は１００００ｐｐｍ／ｃｉｇ．以上、４００００ｐｐｍ／ｃｉｇ．以下としてもよい。このような範囲であれば、香味強度の十分な切り替えを感じることができるとともに、メンソールが結晶化したり紙材料に染み出してくることを抑制できる。 The fragrance is menthol, and the amount of menthol added is 10,000 ppm / cig. 40000 ppm / cig. It is good also as follows. If it is such a range, while being able to feel sufficient switching of flavor intensity | strength, it can suppress that a menthol crystallizes or oozes out to paper materials.
　また、本発明の他の側面に係るたばこ製品は、刻を含むロッド部と、上述したフィルタとを有するものである。このようなたばこ製品によれば、単純な構成でありながら香味強度を切り替え可能とすることができるものとなる。 Further, a tobacco product according to another aspect of the present invention has a rod portion including a cut and the above-described filter. According to such a tobacco product, the flavor intensity can be switched while having a simple configuration.
　なお、本発明における課題を解決するための手段は、可能な限り組み合わせて採用することができる。 In addition, the means for solving the problems in the present invention can be employed in combination as much as possible.
　本発明によれば、単純な構成により香味強度を切り替え可能とする技術を提供することができる。 According to the present invention, it is possible to provide a technique that allows the flavor intensity to be switched with a simple configuration.

　本発明に係るシガレットの実施形態について、図面に基づいて説明する。 Embodiments of a cigarette according to the present invention will be described with reference to the drawings.
＜＜実施形態＞＞
＜シガレットの構成＞
　図１は、本実施形態に係るシガレットの一例を示す斜視図である。シガレット１は、ほぼ円柱形状であり、たばこロッド１１とフィルタ部（単に「フィルタ」とも呼ぶ）１２とを含む。たばこロッド１１は、たばこ刻を巻紙で包むことにより形成される。フィルタ部１２は、セルロースアセテートのような繊維材料で形成された繊維トウなどを素材紙及び成型紙で包んで形成され、内部に香料を含むカプセル保持している。なお、本実施の形態では、シガレット１の軸方向に連設される構成部分の単位をセグメントと呼ぶ。軸方向とはシガレット１の長手方向である。複数のセグメントは成型紙等の紙部材で巻かれ、フィルタ部１２が形成される。また、たばこロッド１１及びフィルタ部１２は、さらにチップペーパーのような紙材料で巻かれることにより連設され、シガレット１が形成される。なお、ほぼ円柱形状であるシガレット１（すなわち、たばこロッド１１及びフィルタ部１２）の曲面を、側面とも呼ぶ。また、後述するように、香料としては例えばメンソールを用いることができる。 << Embodiment >>
<Configuration of cigarette>
FIG. 1 is a perspective view showing an example of a cigarette according to the present embodiment. Cigarette 1 has a substantially cylindrical shape and includes a tobacco rod 11 and a filter portion (also simply referred to as “filter”) 12. The cigarette rod 11 is formed by wrapping a cigarette with a wrapping paper. The filter unit 12 is formed by wrapping a fiber tow formed of a fiber material such as cellulose acetate with a raw paper and a molding paper, and holds a capsule containing a fragrance inside. In the present embodiment, the unit of the constituent parts arranged in the axial direction of the cigarette 1 is called a segment. The axial direction is the longitudinal direction of the cigarette 1. The plurality of segments are wound with a paper member such as molded paper, and the filter unit 12 is formed. Further, the cigarette rod 11 and the filter unit 12 are further connected by being wound with a paper material such as chip paper, whereby the cigarette 1 is formed. In addition, the curved surface of the cigarette 1 (that is, the tobacco rod 11 and the filter portion 12) having a substantially cylindrical shape is also referred to as a side surface. As will be described later, for example, menthol can be used as the fragrance.
　図２は、本実施形態に係るフィルタ部１２の一例を示す斜視図である。フィルタ部１２は、フィルタセグメント１２１と、環状セグメント１２２と、キャビティ（cavity）セグメント１２３と、環状セグメント１２４と、巻紙１２５とを含む。フィルタ部１２は、その側面を巻紙１２５で包まれることにより、複数のセグメントを結合させている。なお、環状セグメント１２２を第１の環状セグメントあるいはＣＨ（Center Hole）１、環状セグメント１２４を第２の環状セグメントあるいはＣＨ（Center Hole）２とも呼ぶ。フィルタセグメント１２１は、一般的な円柱形状のアセテートフィルタにより形成される。また、円柱形状の環状セグメント１２２は、その横断面（すなわち、フィルタ部１２の底面及び上面に平行な断面）のほぼ中心に沿って貫通する通気孔１２２２が設けられたアセテートフィルタにより形成される。なお、通気孔１２２２の周囲に存在する、繊維トウで形成された環状の部分を環状部１２２１とも呼ぶ。キャビティセグメント１２３は、内部が空洞になった領域であり、内部に香料カプセル１２６を保持している。香料カプセル１２６は、例えば、液体状又は粉末状の香料成分を内包するカプセルである。また、環状セグメント１２４は、円柱形状の横断面のほぼ中心に沿って貫通する通気孔１２４２が設けられたアセテートフィルタにより形成される。横断面がほぼ円形である通気孔１２４２の内径は、香料カプセル１２６の直径よりも小さくなっているため、香料カプセル１２６は吸口側に移動できない。なお、通気孔１２４２の周囲に存在する、繊維トウで形成された環状の部分を環状部１２４１とも呼ぶ。なお、便宜上、香料カプセルを保持するキャビティセグメント１２３を、香料セグメントとも呼ぶ。 FIG. 2 is a perspective view showing an example of the filter unit 12 according to the present embodiment. The filter unit 12 includes a filter segment 121, an annular segment 122, a cavity segment 123, an annular segment 124, and a wrapping paper 125. The filter unit 12 has its side surface wrapped with a wrapping paper 125 to combine a plurality of segments. The annular segment 122 is also called a first annular segment or CH (Center Hole) 1, and the annular segment 124 is also called a second annular segment or CH (Center Hole) 2. The filter segment 121 is formed of a general cylindrical acetate filter. Further, the cylindrical annular segment 122 is formed by an acetate filter provided with a vent hole 1222 penetrating substantially along the center of the transverse section (that is, a section parallel to the bottom surface and the top surface of the filter portion 12). An annular portion formed of fiber tows that exists around the air hole 1222 is also referred to as an annular portion 1221. The cavity segment 123 is a region that is hollow inside, and holds the perfume capsule 126 inside. The perfume capsule 126 is, for example, a capsule containing a liquid or powdery perfume component. The annular segment 124 is formed by an acetate filter provided with a vent hole 1242 penetrating along substantially the center of a cylindrical cross section. Since the inner diameter of the air hole 1242 having a substantially circular cross section is smaller than the diameter of the fragrance capsule 126, the fragrance capsule 126 cannot move to the mouth side. An annular portion formed of fiber tows that exists around the vent hole 1242 is also referred to as an annular portion 1241. For convenience, the cavity segment 123 that holds the fragrance capsule is also referred to as a fragrance segment.
　なお、香料が液体状の場合、水性香料を採用しても、油性香料を採用しても良い。また、使用者は、フィルタ部１２の外側から香料カプセル１２６を押圧等することにより、香料カプセル１２６を破壊することができる。香料カプセル１２６が破壊されると、香料カプセル１２６内部の香料成分が放出され、環状セグメント１２２及び環状セグメント１２４に香料成分が担持される。また、香料成分の少なくとも一部が気化又はエアロゾル化し、使用者はこれを吸引することで、香味を感じることができる。なお、香料カプセル１２６は、既存の技術を用いて製造することができる。 In addition, when a fragrance | flavor is a liquid state, even if it employ | adopts an aqueous | water-based fragrance | flavor, you may employ | adopt an oil-based fragrance | flavor. Further, the user can destroy the fragrance capsule 126 by pressing the fragrance capsule 126 from the outside of the filter unit 12. When the fragrance capsule 126 is broken, the fragrance component inside the fragrance capsule 126 is released, and the fragrance component is supported on the annular segment 122 and the annular segment 124. In addition, at least a part of the fragrance component is vaporized or aerosolized, and the user can feel the flavor by sucking it. In addition, the fragrance | flavor capsule 126 can be manufactured using the existing technique.
　本実施形態に係る環状セグメント１２２及び環状セグメント１２４は、径方向の押圧により通気孔１２２２及び通気孔１２４２を塞ぐ（閉孔する）ことができるとともに、所定の復元力を有し、力を加えていない状態では開孔する。 The annular segment 122 and the annular segment 124 according to the present embodiment can close (close) the ventilation hole 1222 and the ventilation hole 1242 by pressing in the radial direction, have a predetermined restoring force, and apply a force. It opens in the absence.
＜動作＞
　図３及び図４は、フィルタ部１２の一例を模式的に表す縦断面図である。図３は、フィルタ部１２に力を加えていない通常の状態を表している。すなわち、図３のフィルタ部１２の場合は、環状セグメント１２２及び環状セグメント１２４の中央を通気孔１２２２及び通気孔１２４２が貫通している。図４は、使用者がフィルタ部１２を横断面の径方向に押圧した状態の一例を表している。すなわち、通気孔１２２２及び通気孔１２４２は、フィルタ部１２の長手方向の中央付近において閉孔している。このとき、キャビティセグメント１２３の内部に存在する香料カプセル１２６は、巻紙１２５の内側に挟まれて破壊され、内包している香料成分が放出される。なお、図４において矢印は使用者の押圧によってフィルタ部１２にかかる力の向きを示している。また、本実施形態に係る環状セグメント１２２及び環状セグメント１２４は所定の復元力を有しているため、図４に示す押圧した状態から力を解放すると、図３に示す力を加えていない状態に遷移する。すなわち、使用者の動作により図３の開孔状態と図４の閉孔状態とを切り替えることができる。 <Operation>
3 and 4 are vertical cross-sectional views schematically showing an example of the filter unit 12. FIG. 3 shows a normal state where no force is applied to the filter unit 12. That is, in the case of the filter portion 12 of FIG. 3, the vent hole 1222 and the vent hole 1242 pass through the centers of the annular segment 122 and the annular segment 124. FIG. 4 illustrates an example of a state in which the user presses the filter unit 12 in the radial direction of the cross section. That is, the vent hole 1222 and the vent hole 1242 are closed near the center in the longitudinal direction of the filter portion 12. At this time, the fragrance capsule 126 present inside the cavity segment 123 is sandwiched and broken inside the wrapping paper 125, and the included fragrance component is released. In addition, in FIG. 4, the arrow has shown the direction of the force applied to the filter part 12 by a user's press. Further, since the annular segment 122 and the annular segment 124 according to the present embodiment have a predetermined restoring force, when the force is released from the pressed state shown in FIG. 4, the force shown in FIG. 3 is not applied. Transition. That is, the user can switch between the open state of FIG. 3 and the closed state of FIG.
　図３に示す力を加えていない状態では、喫煙時に主流煙は主として通気孔１２２２及び通気孔１２４２を通過して使用者の口腔へ導入される。なお、一点鎖線の矢印は使用者に吸引される主流煙の向きを示している。一方、図４に示す押圧した状態では、主流煙は環状部１２２１及び環状部１２４１の一部を通過して使用者の口腔へ導入される。ここで、環状部１２２１及び環状部１２４１は香料を担持しているため、図４に示す押圧した状態においては、図３に示す力を加えていない状態よりも多くの香料成分が使用者の口腔へ導入される。すなわち、本実施形態に係るシガレット１は、使用者が指でフィルタ部１２の一部である環状セグメント１２２及び環状セグメント１２４を押圧したり解放したりすることによって香味強度を双方向的に切り替えることができるようになっている。 In the state where the force shown in FIG. 3 is not applied, the mainstream smoke is mainly introduced into the user's oral cavity through the vent hole 1222 and the vent hole 1242 during smoking. In addition, the arrow of a dashed-dotted line has shown the direction of the mainstream smoke attracted | sucked by a user. On the other hand, in the pressed state shown in FIG. 4, the mainstream smoke passes through part of the annular part 1221 and the annular part 1241 and is introduced into the oral cavity of the user. Here, since the annular portion 1221 and the annular portion 1241 carry a fragrance, in the pressed state shown in FIG. 4, more fragrance components are present in the user's oral cavity than in the state where the force shown in FIG. 3 is not applied. To be introduced. That is, the cigarette 1 according to the present embodiment bidirectionally switches the flavor intensity by pressing or releasing the annular segment 122 and the annular segment 124 that are a part of the filter unit 12 with a finger. Can be done.
＜環状セグメントの構成と通気孔の復元度＞
　次に、通気孔の直径と環状セグメント及びキャビティセグメントの軸方向（フィルタの長手方向）の長さとを変更した場合の、通気孔の断面積の復元度を測定した結果を示す。図５は、復元度の測定を説明するための、フィルタ部１２の一部を示す縦断面図である。図５は、環状セグメント１２２、キャビティセグメント１２３、及び環状セグメント１２４を巻紙１２５で巻き、一体に形成したフィルタ部１２の一部の縦断面図である。復元度の測定では、環状セグメント１２２の通気孔１２２２の直径、及び環状セグメント１２４の通気孔１２４２の直径を同一にして、ＣＨ（Center Hole）径と呼ぶ。また、環状セグメント１２２の軸方向の長さ（換言すれば通気孔１２２２の長さ）をＣＨ長１と呼ぶ。そして、キャビティセグメント１２３の軸方向の長さをCavity長と呼ぶ。同様に、環状セグメント１２４の軸方向の長さ（すなわち、通気孔１２４２の長さ）をＣＨ長２と呼ぶ。 <Structure of annular segment and degree of restoration of vent hole>
Next, the results of measuring the degree of restoration of the cross-sectional area of the vent hole when the diameter of the vent hole and the length of the annular segment and the cavity segment in the axial direction (longitudinal direction of the filter) are shown. FIG. 5 is a longitudinal sectional view showing a part of the filter unit 12 for explaining the measurement of the degree of restoration. FIG. 5 is a longitudinal sectional view of a part of the filter unit 12 formed integrally by winding the annular segment 122, the cavity segment 123, and the annular segment 124 with a wrapping paper 125. In the measurement of the degree of restoration, the diameter of the vent hole 1222 of the annular segment 122 and the diameter of the vent hole 1242 of the annular segment 124 are made the same and are called CH (Center Hole) diameters. In addition, the axial length of the annular segment 122 (in other words, the length of the vent hole 1222) is referred to as CH length 1. The length of the cavity segment 123 in the axial direction is called a Cavity length. Similarly, the axial length of the annular segment 124 (that is, the length of the vent hole 1242) is referred to as CH length 2.
　測定対象の環状セグメント及びキャビティセグメントの詳細は後述するが、通気孔１２２２及び１２４２の直径が、２．０ｍｍ、３．２ｍｍ、５．０ｍｍ及び６．０ｍｍのものを用いた。また、環状セグメントの軸方向の長さは、５．０ｍｍ、７．５ｍｍ、及び１４．０ｍｍのものを用いた。なお、繊維トウのスペック（仕様）は一般的なフィルタに用いられるものであり、５．０Ｙ４７０００、可塑剤量１２％とした。なお、環状セグメント１２２、キャビティセグメント１２３、及び環状セグメント１２４の横断面外径は、一般的なシガレットと同様に７．５ｍｍ程度とした。 Although details of the annular segment and the cavity segment to be measured will be described later, the vent holes 1222 and 1242 have diameters of 2.0 mm, 3.2 mm, 5.0 mm, and 6.0 mm. In addition, the axial lengths of the annular segments were 5.0 mm, 7.5 mm, and 14.0 mm. In addition, the specification (specification) of the fiber tow is used for a general filter, and is 5.0Y47000 and the plasticizer amount is 12%. The outer diameters of the cross sections of the annular segment 122, the cavity segment 123, and the annular segment 124 were set to about 7.5 mm as in the case of a general cigarette.
　ここで、繊維トウのスペックを示す「５．０」とは、単繊度が５．０デニールであることを表し、「Ｙ」とは断面形状がＹ字型であることを表し、「４７０００」とは総繊度が４７０００デニールであることを表している。フィルタに用いられる一般的な繊維トウは、単繊度が１．５～８．０デニール程度、断面形状が円形、楕円形、Ｙ字型、Ｘ字型、Ｉ字型等、総繊度が１５０００～５００００デニール程度である。 Here, “5.0” indicating the specification of the fiber tow indicates that the single fineness is 5.0 denier, “Y” indicates that the cross-sectional shape is Y-shaped, and “47000”. Represents that the total fineness is 47,000 denier. General fiber tows used in filters have a single fineness of about 1.5 to 8.0 denier, a circular cross section, an ellipse, a Y shape, an X shape, an I shape, etc., and a total fineness of 15000 or more. It is about 50000 denier.

　図７は、上記の測定を下記サンプル（１）～（７）を用いて行い、復元率（加重後の面積／加重前の面積）を求めた結果を示す表である。なお、通気孔が潰れて全く戻らなくなるのでなければ（すなわち復元率がほぼ０でない限り）、香味強度の切り替えはある程度感じられる。

（７）ＣＨ径：６．０ｍｍ、ＣＨ長１：７．５ｍｍ、Cavity長：５．０ｍｍ、ＣＨ長２：７．５ｍｍ FIG. 7 is a table showing the results of performing the above measurement using the following samples (1) to (7) and obtaining the restoration rate (area after weighting / area before weighting). In addition, unless the ventilation hole is crushed and does not return at all (that is, unless the restoration rate is almost 0), the change of flavor intensity is felt to some extent.
(1) CH diameter: 2.0 mm, CH length 1: 5.0 mm, Cavity length: 5.0 mm, CH length 2: 14.0 mm
(2) CH diameter: 3.2 mm, CH length 1: 5.0 mm, Cavity length: 5.0 mm, CH length 2: 14.0 mm
(3) CH diameter: 3.2 mm, CH length 1: 5.0 mm, Cavity length: 2.5 mm, CH length 2: 14.0 mm
(4) CH diameter: 2.0 mm, CH length 1: 7.5 mm, Cavity length: 5.0 mm, CH length 2: 7.5 mm
(5) CH diameter: 3.2 mm, CH length 1: 7.5 mm, Cavity length: 5.0 mm, CH length 2: 7.5 mm
(6) CH diameter: 5.0 mm, CH length 1: 7.5 mm, Cavity length: 5.0 mm, CH length 2: 7.5 mm
(7) CH diameter: 6.0 mm, CH length 1: 7.5 mm, Cavity length: 5.0 mm, CH length 2: 7.5 mm
　復元率の列に示すように、ＣＨ径が５．０ｍｍの場合に最も復元率は高くなり、ＣＨ径が５．０ｍｍよりも小さい場合にはＣＨ径が大きくなるにつれて復元率も高くなった。しかしながら、ＣＨ径が２．０ｍｍの場合であっても通気孔が潰れて戻らなくなることはなかった。したがって、ＣＨ径はおおむね２．０ｍｍ以上、且つ６．０ｍｍ以下の範囲で任意に決めるようにすればよい。また、サンプル（２）とサンプル（３）との比較によれば、Cavity長が２．５ｍｍの場合と５．０ｍｍの場合とで通気孔横断面積の復元率にそれほど差は表れなかった。したがって、Cavity長はおおむね２．５ｍｍ以上、且つ５．０ｍｍ以下の範囲において、香料カプセルを保持するのに好ましい大きさを適宜選択することができる。また、サンプル（１）～サンプル（７）によれば、何れの場合も、通気孔が潰れて戻らなくなることはなかった。また、サンプル（１）～（５）に示すように、ＣＨ長１及びＣＨ長２の長さが異なる場合であっても、成型紙で一体に形成されている環状セグメントの間で復元率に大きな差は表れなかった。また、同一のＣＨ径、同一のCavity長の場合は、２つの環状セグメントの長さの合計（ＣＨ長１＋ＣＨ長２）が長い方が復元率は大きくなった。したがって、複数のセグメントからなるフィルタ部を採用する場合も、２つの環状セグメントの軸方向の長さの合計が１５．０ｍｍ以上であれば、０．１程度の復元率が期待できる（例えば、図７のサンプル（４）を参照）。なお、使用者が指で潰すための領域や使用者が咥えるための領域を確保するには、環状セグメントの長さ（ＣＨ長１及びＣＨ長２）の合計がおおむね１５．０ｍｍ以上あることが好ましい。 As shown in the column of restoration rate, the restoration rate was highest when the CH diameter was 5.0 mm, and when the CH diameter was smaller than 5.0 mm, the restoration rate was increased as the CH diameter was increased. However, even when the CH diameter was 2.0 mm, the vent hole was not crushed and did not return. Therefore, the CH diameter may be arbitrarily determined within a range of approximately 2.0 mm or more and 6.0 mm or less. Moreover, according to the comparison between the sample (2) and the sample (3), there was not much difference in the restoration ratio of the vent hole cross-sectional area when the Cavity length was 2.5 mm and when it was 5.0 mm. Therefore, the preferred size for holding the fragrance capsule can be appropriately selected within the range of the cavity length of 2.5 mm or more and 5.0 mm or less. Further, according to Sample (1) to Sample (7), in any case, the vent hole was not crushed and could not be returned. Further, as shown in samples (1) to (5), even when the CH length 1 and the CH length 2 are different, the restoration rate is improved between the annular segments formed integrally with the molded paper. There was no big difference. Further, in the case of the same CH diameter and the same Cavity length, the restoration rate increased as the total of the lengths of the two annular segments (CH length 1 + CH length 2) was longer. Accordingly, even when a filter unit composed of a plurality of segments is employed, a restoration rate of about 0.1 can be expected if the total axial length of the two annular segments is 15.0 mm or more (for example, FIG. 7 sample (4)). In addition, the total of the lengths of the annular segments (CH length 1 and CH length 2) is approximately 15.0 mm or more in order to secure an area for the user to crush with a finger and an area for the user to bark. Is preferred.
＜環状セグメントの構成と官能評価＞
　次に、図７に示した復元度を測定したサンプル（１）～（７）について、官能評価を行った結果を示す。図８に示すように、官能評価に用いたサンプルは図７（１）～（７）に示したセグメントに加え、フィルタセグメント１２１を含むものである。また、フィルタセグメント１２１の軸方向の長さをFilter長と呼ぶ。なお、他の構成は図５の例と同様である。 <Structure of ring segment and sensory evaluation>
Next, the results of sensory evaluation of the samples (1) to (7) measured for the degree of restoration shown in FIG. 7 are shown. As shown in FIG. 8, the sample used for the sensory evaluation includes a filter segment 121 in addition to the segments shown in FIGS. 7 (1) to (7). The length of the filter segment 121 in the axial direction is referred to as a filter length. Other configurations are the same as those in the example of FIG.
　なお、環状セグメント１２２の環状部１２２１及び環状セグメント１２４の環状部１２４１の可塑剤量は、いずれも１２％とした。また、フィルタセグメント、環状セグメント１２２の環状部１２２１、及び環状セグメント１２４の環状部１２４１のスペックは、２．８Ｙ３５０００とした。図９は、官能評価に用いたフィルタ部の構成を説明するための表である。図９に示すロット（Lot）１～ロット７は、環状セグメントのＣＨ長を５．０ｍｍ～１４．０ｍｍとし、Cavity長を２．５ｍｍ又は５．０ｍｍとし、フィルタ部の全長が３０．０ｍｍになるようにFilter長を調整した。図９に示すロット１～７のＣＨ長１、Cavity長及びＣＨ長２はそれぞれ、図７に示すサンプル（１）～（７）のＣＨ長１、Cavity長及びＣＨ長２に対応するものである。また、エタノールを溶媒としたｌメンソール（l-Menthol）溶液を２０μｌシリンジで環状セグメント１２２及び環状セグメント１２４に添加した。なお、メンソール濃度は、刻量６５０ｍｇとして計算すると、シガレット当たり１０，０００ｐｐｍであった。 It should be noted that the plasticizer amounts of the annular portion 1221 of the annular segment 122 and the annular portion 1241 of the annular segment 124 were both 12%. The specifications of the filter segment, the annular portion 1221 of the annular segment 122, and the annular portion 1241 of the annular segment 124 were 2.8Y35000. FIG. 9 is a table for explaining the configuration of the filter unit used for sensory evaluation. In lots 1 to 7 shown in FIG. 9, the CH length of the annular segment is set to 5.0 mm to 14.0 mm, the cavity length is set to 2.5 mm or 5.0 mm, and the total length of the filter portion is 30.0 mm. Adjusted the filter length so that The CH length 1, Cavity length and CH length 2 of lots 1 to 7 shown in FIG. 9 correspond to the CH length 1, Cavity length and CH length 2 of samples (1) to (7) shown in FIG. 7, respectively. is there. Further, a l-Menthol solution using ethanol as a solvent was added to the annular segment 122 and the annular segment 124 with a 20 μl syringe. The menthol concentration was 10,000 ppm per cigarette when calculated with an increment of 650 mg.
　パネルは３名の評価担当者であり、評価結果は３名の平均値である。評価手順は、（１）環状セグメントを押圧しない状態（すなわち開孔状態。「Ｏｐｅｎ」とも呼ぶ）での吸引、及び（２）環状セグメントを押圧した状態（すなわち閉孔状態。「Ｃｌｏｓｅ」とも呼ぶ）での吸引を、任意のペースで３回繰り返した。そして、計６回（順に「１ｓｔ」～「６ｔｈ」とも呼ぶ）の吸引におけるそれぞれの香味強度（「メンソール感」とも呼ぶ）をＶＡＳ（Visual Analogue Scale：視覚的評価スケール）を用いて評価した。なお、ＶＡＳは０～１００までのスケールを有し、最もメンソール感を強く感じたときが１００となるようなスケールを用いた。 The panel has 3 persons in charge of evaluation, and the evaluation result is an average value of 3 persons. The evaluation procedure includes (1) suction in a state where the annular segment is not pressed (that is, an open state, also referred to as “Open”), and (2) a state where the annular segment is pressed (that is, a closed state, also referred to as “Close”). ) Was repeated three times at an arbitrary pace. Then, each flavor intensity (also referred to as “menthol feeling”) in a total of 6 times (also referred to as “1st” to “6th” in order) was evaluated using a VAS (Visual Analogue Scale). Note that the VAS has a scale of 0 to 100, and the scale is 100 when the menthol feeling is strongest.
　図１０の表は、縦にロット１～ロット７の各項目を有し、横に１ｓｔ～６ｔｈの各回、３回のＯｐｅｎ時（１ｓｔ、３ｒｄ、５ｔｈ）と３回のＣｌｏｓｅ時（２ｎｄ、４ｔｈ、６ｔｈ）の各平均値、並びにＯｐｅｎ時の平均値とＣｌｏｓｅ時の平均値の差の各項目を有しており、それぞれの評価結果を示す値が示されている。図１１は、評価結果を示す折れ線グラフである。各ロットとも、Ｏｐｅｎ時とＣｌｏｓｅ時とで香味強度の切り替えが感じられた。また、図１２は、図１０に示すＯｐｅｎ時の平均値とＣｌｏｓｅ時の平均値との差を、ロットごとに棒グラフで示した図である。Ｏｐｅｎ時とＣｌｏｓｅ時とにおける香味強度の違いは、ロット間で多少の差が認められ、いずれのロットにおいても十分な香味強度の切り替えが感じられた。 The table of FIG. 10 has items of lot 1 to lot 7 in the vertical direction, each time from 1st to 6th, 3 times open (1st, 3rd, 5th) and 3 times close (2nd, 4th). , 6th), and the difference between the average value at the time of Open and the average value at the time of Close, and values indicating the respective evaluation results are shown. FIG. 11 is a line graph showing the evaluation results. In each lot, a change in flavor intensity was felt between Open and Close. FIG. 12 is a graph showing the difference between the average value at the time of Open and the average value at the time of Close shown in FIG. 10 as a bar graph for each lot. The difference in flavor intensity between Open and Close was somewhat different between lots, and a sufficient change in flavor intensity was felt in any lot.
　＜環状セグメントの長さ、通気孔の直径、及び香料の添加量と香味強度の官能評価＞
　次に、環状セグメントの長さ、通気孔の直径、及び香料の添加量が異なる場合の、開孔状態及び閉孔状態における香味強度（「メンソール感」とも呼ぶ）の官能評価について説明する。 <Sensory evaluation of the length of the annular segment, the diameter of the air vent, and the added amount of flavor and flavor intensity>
Next, sensory evaluation of flavor strength (also referred to as “menthol feeling”) in the open and closed states when the length of the annular segment, the diameter of the air holes, and the amount of the fragrance added are different will be described.
　測定対象の環状セグメントとしては、通気孔の直径（「ＣＨ径」とも呼ぶ）が、２．０ｍｍ、３．２ｍｍ、５．０ｍｍ及び６．０ｍｍのものを用いた。また、環状セグメントの軸方向の長さ（「ＣＨ長」とも呼ぶ）は、１５．０ｍｍ、２０．０ｍｍ、２７．０ｍｍ、３２．０ｍｍのものを用いた。なお、本官能評価では、１つのセグメント（環状セグメント）からなるフィルタを用いている。図７のサンプル（１）～（５）によれば、複数のセグメントを採用する場合も、環状セグメントの軸方向の長さの合計に応じて通気孔断面積の復元率も大きくなると考えられるため、本官能評価では環状セグメントの全長を１つのセグメントに見立てて評価を行った。繊維トウのスペックは、５．０Ｙ４７０００、可塑剤量１２％とした。香料は、２種類の濃度のｌメンソール（l-Menthol）２０μｌをシリンジで注入した。刻量６５０ｍｇとして計算すると、各濃度の場合の添加量は５，０００ｐｐｍ／ｃｉｇ．、及び１０，０００ｐｐｍ／ｃｉｇ．に相当する。 As the annular segment to be measured, those having a vent hole diameter (also referred to as “CH diameter”) of 2.0 mm, 3.2 mm, 5.0 mm, and 6.0 mm were used. The length of the annular segment in the axial direction (also referred to as “CH length”) was 15.0 mm, 20.0 mm, 27.0 mm, or 32.0 mm. In this sensory evaluation, a filter composed of one segment (annular segment) is used. According to the samples (1) to (5) in FIG. 7, even when a plurality of segments are employed, it is considered that the restoration rate of the vent hole cross-sectional area increases according to the total axial length of the annular segments. In this sensory evaluation, the entire length of the cyclic segment was evaluated as one segment. The specification of the fiber tow was 5.0Y47000, and the plasticizer amount was 12%. As the fragrance, 20 μl of l-Menthol having two concentrations was injected with a syringe. When calculated as an amount of 650 mg, the amount added for each concentration is 5,000 ppm / cig. , And 10,000 ppm / cig. It corresponds to.
　官能評価は、図９に示すロット１～ロット７の場合と同様の手順で行った。すなわち、パネルは３名の評価担当者であり、ＯｐｅｎとＣｌｏｓｅとを交互に６回（６パフ）繰り返し、メンソール感をＶＡＳで評価した。評価結果は３名の平均値である。 Sensory evaluation was performed in the same procedure as in the case of lot 1 to lot 7 shown in FIG. That is, the panel consists of three persons in charge of evaluation, and Open and Close were alternately repeated 6 times (6 puffs), and the menthol feeling was evaluated by VAS. An evaluation result is an average value of three persons.
　図１３～図１６は、香料添加量が５，０００ｐｐｍ／ｃｉｇ．の場合のメンソール感の評価結果を示す表である。各表は、縦にＣＨ径（２．０ｍｍ、３．２ｍｍ、５．０ｍｍ及び６．０ｍｍ）、横に１ｓｔ～６ｔｈの各回、３回のＯｐｅｎ時（１ｓｔ、３ｒｄ、５ｔｈ）と３回のＣｌｏｓｅ時（２ｎｄ、４ｔｈ、６ｔｈ）の各平均値、並びにＯｐｅｎ時の平均値とＣｌｏｓｅ時の平均値の差の各項目を有しており、それぞれの評価結果を示す値が示されている。 FIGS. 13 to 16 show that the amount of the fragrance added is 5,000 ppm / cig. It is a table | surface which shows the evaluation result of the menthol feeling in the case of. Each table shows the CH diameter (2.0 mm, 3.2 mm, 5.0 mm, and 6.0 mm) in the vertical direction, each time from 1st to 6th in the horizontal direction, 3 times in the open state (1st, 3rd, 5th) and 3 times. Each item has an average value at the time of closing (2nd, 4th, 6th) and a difference between the average value at the time of opening and the average value at the time of closing, and values indicating the respective evaluation results are shown.
　また、図１７は、縦にＣＨ径、横にＣＨ長をとり、Ｏｐｅｎ時の平均値とＣｌｏｓｅ時の平均値との差を示す表である。 FIG. 17 is a table showing the difference between the average value during Open and the average value during Close, with the CH diameter in the vertical direction and the CH length in the horizontal direction.
　Ｏｐｅｎ時とＣｌｏｓｅ時との評価結果の平均値の差は、香味強度の違いを数値で表したものといえる。そして、香料添加量が５，０００ｐｐｍ／ｃｉｇ．の場合、ＣＨ径及びＣＨ長がいずれの場合も、香味強度の切り替えは数値に表れた。また、図１７に示すように、ＣＨ径及びＣＨ長によって、Ｏｐｅｎ時とＣｌｏｓｅ時とで香味強度の差に大きな違いは表れなかった。 It can be said that the difference in the average value of the evaluation results at the time of Open and at the time of Close represents the difference in flavor intensity as a numerical value. And the fragrance | flavor addition amount is 5,000 ppm / cig. In the case of, the change in flavor intensity appeared in the numerical values in both cases of the CH diameter and the CH length. Moreover, as shown in FIG. 17, the difference in flavor intensity by the time of Open and the time of Close did not show a big difference by CH diameter and CH length.
　図１８～図２１は、香料添加量が１０，０００ｐｐｍ／ｃｉｇ．の場合のメンソール感の評価結果を示す表である。各表は、縦にＣＨ径（２．０ｍｍ、３．２ｍｍ、５．０ｍｍ及び６．０ｍｍ）、横に１ｓｔ～６ｔｈの各回、３回のＯｐｅｎ時（１ｓｔ、３ｒｄ、５ｔｈ）と３回のＣｌｏｓｅ時（２ｎｄ、４ｔｈ、６ｔｈ）の各平均値、並びにＯｐｅｎ時の平均値とＣｌｏｓｅ時の平均値の差の各項目を有しており、それぞれの評価結果を示す値が示されている。 FIG. 18 to FIG. 21 show that the perfume addition amount is 10,000 ppm / cig. It is a table | surface which shows the evaluation result of the menthol feeling in the case of. Each table shows the CH diameter (2.0 mm, 3.2 mm, 5.0 mm, and 6.0 mm) in the vertical direction, each time from 1st to 6th in the horizontal direction, 3 times in the open state (1st, 3rd, 5th) and 3 times. Each item has an average value at the time of closing (2nd, 4th, 6th) and a difference between the average value at the time of opening and the average value at the time of closing, and values indicating the respective evaluation results are shown.
　また、図２２は、縦にＣＨ径、横にＣＨ長をとり、Ｏｐｅｎ時の平均値とＣｌｏｓｅ時の平均値との差を示す表である。 FIG. 22 is a table showing the difference between the average value during Open and the average value during Close, with the CH diameter in the vertical direction and the CH length in the horizontal direction.
　香料添加量が１０，０００ｐｐｍ／ｃｉｇ．の場合、ＣＨ径及びＣＨ長がいずれの場合も、香味強度の切り替えは十分に感じることができた。また、図２２に示すように、香料添加量が１０，０００ｐｐｍ／ｃｉｇ．の場合も、香料添加量が５，０００ｐｐｍ／ｃｉｇ．の場合と同様に、ＣＨ径及びＣＨ長によって、Ｏｐｅｎ時とＣｌｏｓｅ時とで香味強度の差に大きな違いは表れなかった。なお、Ｏｐｅｎ時とＣｌｏｓｅ時との香味強度の差は、いずれのＣＨ径及びＣＨ長においても、５，０００ｐｐｍ／ｃｉｇ．の場合よりも大きな値となっている。そして、この数値の差は、評価者に実感として感じとれるものであった。したがって、添加量は１０，０００ｐｐｍ／ｃｉｇ．の方が好ましいことがわかった。ただし、添加量が４０，０００ｐｐｍ／ｃｉｇ．を超えると、メンソールが結晶化したりチップペーパー等の紙材料の外側に染み出し、染み巻きになったりするおそれがある。したがって、添加量は４０，０００ｐｐｍ／ｃｉｇ．以下であることが好ましい。 Fragrance addition amount is 10,000 ppm / cig. In the case of, the change in flavor intensity could be sufficiently felt regardless of the CH diameter and CH length. Moreover, as shown in FIG. 22, the amount of the fragrance added is 10,000 ppm / cig. In this case, the fragrance addition amount is 5,000 ppm / cig. As in the case of, the difference in flavor intensity between Open and Close did not appear greatly depending on the CH diameter and CH length. Note that the difference in flavor intensity between Open and Close is 5,000 ppm / cig. The value is larger than the case of. And the difference of this numerical value was felt as an actual feeling to the evaluator. Therefore, the addition amount is 10,000 ppm / cig. It was found that is preferable. However, the addition amount is 40,000 ppm / cig. If it exceeds 1, the menthol may crystallize or ooze out to the outside of the paper material such as chip paper and become wound around. Therefore, the addition amount is 40,000 ppm / cig. The following is preferable.
　上述の実験結果によれば、第１の環状セグメント及び第２の環状セグメントの通気孔の直径が２．０ｍｍ以上且つ６．０ｍｍ以下、第１の環状セグメント及び第２の環状セグメントの長手方向の長さの合計が１５．０ｍｍ以上であれば、香味強度の切り替えを十分に感じられることがわかる。なお、シガレット１を一般的な長さとするためには、環状セグメントの軸方向の長さは、３２．０ｍｍ程度以下であることが好ましい。また、シガレット１を一般的な太さとするためには、通気孔の直径は６．０ｍｍ程度以下であることが好ましい。 According to the above experimental results, the diameters of the vent holes of the first annular segment and the second annular segment are 2.0 mm or more and 6.0 mm or less, and the longitudinal direction of the first annular segment and the second annular segment is If the total length is 15.0 mm or more, it can be seen that the change in flavor intensity can be sufficiently felt. In order to make the cigarette 1 have a general length, the length of the annular segment in the axial direction is preferably about 32.0 mm or less. Moreover, in order to make the cigarette 1 into a general thickness, the diameter of the air hole is preferably about 6.0 mm or less.
　換言すれば、第１の環状セグメント及び第２の環状セグメントは、香料を担持した状態において、６０Ｎの力による１０秒間の横断面の径方向の押圧と、解放とを７回反復した後、通気孔の断面積が０．３ｍｍ２以上に復元することが好ましい。０．３ｍｍ２以上とは、図７に示したサンプル（４）の場合の加重後の通気孔の断面積に基づく概ねの値である。 In other words, the first annular segment and the second annular segment are subjected to 10-second cross-sectional radial pressing and releasing with a force of 60 N in a state where the fragrance is carried, after being repeated seven times, and then passed through. It is preferable that the cross-sectional area of the pores is restored to 0.3 mm 2 or more. 0.3 mm 2 or more is an approximate value based on the cross-sectional area of the vent hole after weighting in the case of the sample (4) shown in FIG.
　また、香料は、例えばメンソールを用いることができる。香料としてメンソールが用いられる場合、添加量は１０，０００ｐｐｍ／ｃｉｇ．以上４０，０００ｐｐｍ／ｃｉｇ．以下であることが好ましい。 Also, for example, menthol can be used as the fragrance. When menthol is used as a fragrance, the amount added is 10,000 ppm / cig. 40,000 ppm / cig. The following is preferable.
＜その他の変形＞
　上述の実施形態を総括すると、香味強度の切り替えを体験できるたばこ製品は、押圧により開孔状態と閉孔状態とを切り替え可能であり、香料を担持するフィルタを備えることにより実現することができる。具体的には、香料を担持した状態において、フィルタの径方向の押圧により通気孔を塞ぐことができるとともに所定の復元力を有し、押圧の解放から３０秒後に通気孔の断面積が０．３ｍｍ２以上に復元する環状セグメントを有することが望ましい。このような条件を満たせば、通常の喫煙時において香味強度の切り替えを十分に感じることができる。 <Other variations>
To summarize the above-described embodiment, a tobacco product that can experience a change in flavor intensity can be switched between an open state and a closed state by pressing, and can be realized by including a filter carrying a fragrance. Specifically, in a state where the fragrance is carried, the vent hole can be closed by pressing in the radial direction of the filter and has a predetermined restoring force. After 30 seconds from the release of the press, the cross-sectional area of the vent hole is 0. It is desirable to have an annular segment that restores to 3 mm 2 or more. If such conditions are satisfied, the change of flavor intensity can be sufficiently felt during normal smoking.
　フィルタ部１２は、フィルタセグメント１２１を有していなくてもよい。フィルタセグメント１２１がない場合も香味強度の切り替えを十分に感じることができる。ただし、フィルタセグメント１２１を設けることで、フィルタ本来の濾過（タールやニコチンの吸着）や煙の冷却といった効果が得られるとともに、環状セグメント１２２及び環状セグメント１２４に担持される香料がたばこロッド１１の刻に移ってしまうことを抑制することができる。また、フィルタセグメント１２１によれば、刻がフィルタ部１２内へ侵入するのを抑制することができる。 The filter unit 12 may not have the filter segment 121. Even when there is no filter segment 121, it is possible to sufficiently sense the change in flavor intensity. However, by providing the filter segment 121, the effects such as filtering (adsorption of tar and nicotine) and smoke cooling can be obtained, and the fragrance carried on the annular segment 122 and the annular segment 124 can be engraved on the tobacco rod 11. Can be suppressed. Further, according to the filter segment 121, it is possible to suppress the intrusion into the filter unit 12.
　また、任意のたばこ製品に装着できるような上述のいずれかに示すフィルタ部を提供するようにしてもよい。たばこ製品とは、例えば紙巻たばこ（フィルタシガレット、両切たばこ（フィルタ無し））、シガー（葉巻）、シガリロ等が例示できる。 Moreover, you may make it provide the filter part shown in either of the above which can be mounted | worn with arbitrary tobacco products. Examples of tobacco products include cigarettes (filter cigarettes, double-cut cigarettes (no filter)), cigars (cigars), cigarillos, and the like.
　フィルタ部１２、特に環状セグメント及びキャビティセグメントを包む成型紙、素材紙、チップペーパー等の紙材料は、液状の香料を透過しない素材で形成されていることが好ましい。このようにすれば、香料がシガレットの断面外周側に滲み出し、染み巻きになることを抑制できる。香料を透過しない素材とは、例えば、香料の性質に応じて、撥水性又は撥油性を有する素材を採用することができる。 The paper material such as molding paper, raw paper, and chip paper that wraps around the filter portion 12, particularly the annular segment and the cavity segment, is preferably formed of a material that does not transmit liquid fragrance. If it does in this way, it can control that a fragrance oozes to the section perimeter side of a cigarette, and becomes a stain winding. For example, a material having water repellency or oil repellency can be adopted as the material that does not transmit the fragrance.
　なお、上記のような構成のフィルタ部１２について、香味強度の切り替えを感じるために好ましい通気孔の復元率等の範囲や、これを実現するトウスペック、ＣＨ長及びＣＨ径の組み合わせ等をより詳細に特定するようにしてもよい。また、フィルタ部の強度や復元率を確保するために成型紙やチップペーパーの材質や坪量について、好ましいものを選択するようにしてもよい。 In addition, about the filter part 12 of the above structure, in order to feel the change of flavor intensity, a range such as a preferable restoration rate of the vent hole, a toe spec, a combination of CH length and CH diameter, etc. that realize this are more detailed. You may make it specify. Moreover, you may make it select a preferable thing about the material and basic weight of a molding paper or chip paper in order to ensure the intensity | strength of a filter part, and a restoration rate.
