　本発明は、非加熱型香味吸引器に関する。 The present invention relates to a non-heating type flavor inhaler.
　従来、通常の紙巻きたばこ（シガレット）の代替品として、刻みたばこや揮発生着香剤（メントールなど）に代表される小片状の香味源を充填する筒状の筒状部材と、ユーザに吸引される吸い口部とを備えた非加熱型香味吸引器が知られている（特許文献１参照）。 Conventionally, as an alternative to ordinary cigarettes (cigarettes), a cylindrical member that is filled with a small piece of flavor source typified by chopped cigarettes and volatile raw flavoring agents (such as menthol), and a user sucked by the user There is known a non-heating type flavor inhaler provided with a mouthpiece (see Patent Document 1).
　この種の非加熱型香味吸引器では、筒状部材は、空洞を形成する筒状の外壁を有するとともに、空洞内に一対のフィルタ壁を有している。具体的に、筒状部材は、空気を流入する一方の端部側に設けられるフィルタ壁と、空気を流出する他方の端部側に設けられるフィルタ壁とを有している。なお、当該一対のフィルタ壁の間には、香味源が充填されている。このような構成の非加熱型香味吸引器によれば、香味源の燃焼を伴うことなくユーザに香味成分を提供することができる。 In this type of non-heated flavor inhaler, the cylindrical member has a cylindrical outer wall forming a cavity and a pair of filter walls in the cavity. Specifically, the cylindrical member has a filter wall provided on one end side through which air flows and a filter wall provided on the other end side through which air flows out. Note that a flavor source is filled between the pair of filter walls. According to the non-heating type flavor inhaler of such a structure, a flavor component can be provided to a user without burning of a flavor source.
　ところで、今回、本発明者らが上記従来技術をより好適なものとすべく、改善案について種々の検討を行ったところ、新たな課題を見出した。具体的に、従来技術に係る非加熱型香味吸引器では、香味吸引開始時において、ユーザの吸引動作に伴って吸い口側に香味源が移動する。 By the way, this time, the present inventors have conducted various studies on improvement plans in order to make the conventional technology more suitable, and found a new problem. Specifically, in the non-heating type flavor inhaler according to the prior art, the flavor source moves to the mouthpiece side in accordance with the user's suction operation at the start of flavor suction.
　このとき、香味源の移動の程度が顕著であると、ユーザは、かかる香味源のフィルタ壁への衝突によって生じる衝撃を吸い口部から受けることになるため、一般的なシガレットを吸引する場合に比べて、違和感を感じてしまうという課題があった。 At this time, if the degree of movement of the flavor source is significant, the user receives an impact caused by the collision of the flavor source with the filter wall from the mouthpiece, and therefore when sucking a general cigarette In comparison, there was a problem of feeling uncomfortable.

　次に、第２外壁孔４０ｂの構成について説明する。図３に示すように、第２外壁孔４０ｂは、第２端部２２が下に位置するように軸線ＡＸ方向を鉛直方向Ｖｄに沿って向けた状態で、空洞１５に充填された香味源３０の上側端部３０ａと第１フィルタ壁５１との間に設けられている。 Next, the configuration of the second outer wall hole 40b will be described. As shown in FIG. 3, the second outer wall hole 40 b is a flavor source 30 filled in the cavity 15 in a state in which the axis AX direction is directed along the vertical direction Vd so that the second end portion 22 is located below. Is provided between the upper end 30 a of the first filter wall 51 and the first filter wall 51.
　また、本実施形態では、第２外壁孔４０ｂを複数有する。具体的に、筒状部材１０が、複数の第２外壁孔４０ｂ１乃至４０ｂ３を有する。複数の第２外壁孔４０ｂ１乃至４０ｂ３は、筒状部材１０の軸線ＡＸを基準として、筒状部材１０の外壁１１の両側のそれぞれに、対称関係を有するように形成されている。つまり、本実施形態では、複数の第２外壁孔４０ｂ１乃至４０ｂ３が、一対形成されている。 In the present embodiment, a plurality of second outer wall holes 40b are provided. Specifically, the cylindrical member 10 has a plurality of second outer wall holes 40b1 to 40b3. The plurality of second outer wall holes 40b1 to 40b3 are formed so as to have a symmetrical relationship on both sides of the outer wall 11 of the tubular member 10 with respect to the axis AX of the tubular member 10. That is, in this embodiment, a plurality of second outer wall holes 40b1 to 40b3 are formed as a pair.
　具体的に、本実施形態では、筒状部材１０は、外壁１１の一方側に３つの第２外壁孔４０ｂ１乃至４０ｂ３を有し、外壁１１の他方側に３つの第２外壁孔４０ｂ１乃至４０ｂ３を有する。 Specifically, in the present embodiment, the tubular member 10 has three second outer wall holes 40 b 1 to 40 b 3 on one side of the outer wall 11, and three second outer wall holes 40 b 1 to 40 b 3 on the other side of the outer wall 11. Have.
　なお、第２外壁孔４０ｂの数は、これに限定されるものではない。さらに、第２外壁孔４０ｂは、筒状部材１０の軸線ＡＸを基準として、筒状部材１０の外壁１１の一方側のみに形成されていてもよい。 Note that the number of the second outer wall holes 40b is not limited to this. Further, the second outer wall hole 40 b may be formed only on one side of the outer wall 11 of the cylindrical member 10 with reference to the axis AX of the cylindrical member 10.
　また、第２外壁孔４０ｂの外壁孔数と、直径と、開口面積とは、第１外壁孔４０ａと同一であってもよいし、異なってもよい。なお、第２外壁孔４０ｂ１乃至４０ｂ３のそれぞれは、配置される位置を除き、同様の構成であるため、本実施形態では、第２外壁孔４０ｂ１乃至４０ｂ３を、単に第２外壁孔４０ｂとして適宜示す。 Further, the number of outer wall holes, the diameter, and the opening area of the second outer wall hole 40b may be the same as or different from those of the first outer wall hole 40a. Since each of the second outer wall holes 40b1 to 40b3 has the same configuration except for the position where it is disposed, in the present embodiment, the second outer wall holes 40b1 to 40b3 are simply indicated as the second outer wall holes 40b as appropriate. .
　（３）作用・効果
　以上説明したように、本実施形態に係る非加熱型香味吸引器１は、空洞１５を形成する外壁１１を有する筒状部材１０と、筒状部材１０の空洞１５に充填される香味源３０とを有する。 (3) Operation and Effect As described above, the non-heating type flavor inhaler 1 according to the present embodiment fills the cylindrical member 10 having the outer wall 11 that forms the cavity 15 and the cavity 15 of the cylindrical member 10. Flavor source 30 to be used.
　筒状部材１０は、空気が流入する第１端部２１と、空気が流出する第２端部２２とを有するとともに、空気が流入する第１外壁孔４０ａと第２外壁孔４０ｂとを有する。また、第１端部２１には、第１フィルタ壁５１が設けられ、第２端部２２には、第２フィルタ壁５２が設けられている。 The cylindrical member 10 has a first end 21 through which air flows in and a second end 22 through which air flows out, and a first outer wall hole 40a and a second outer wall hole 40b through which air flows. The first end 21 is provided with a first filter wall 51, and the second end 22 is provided with a second filter wall 52.
　ここで、ユーザが、図２に示すような状態の非加熱型香味吸引器１から香味の吸引を開始した際に、香味源３０は、空気の流出先である第２端部２２側に向かって移動し、第２フィルタ壁５２に密集しようとする。 Here, when the user starts sucking flavor from the non-heated flavor inhaler 1 in the state shown in FIG. 2, the flavor source 30 is directed toward the second end 22 side, which is the outflow destination of air. To move to the second filter wall 52.
　本実施形態に係る非加熱型香味吸引器１では、筒状部材１０の空洞１５には、第１端部２１と第１外壁孔４０ａと第２外壁孔４０ｂとから空気が流入する。従って、筒状部材１０の第１端部２１のみから空気が流入する場合、即ち、軸線ＡＸ方向のみに沿った空気が流入する場合に比べて、第２フィルタ壁５２側に向かう空気の流れの内、軸線ＡＸ方向のみに沿った空気の流れが抑制される。 In the non-heating type flavor inhaler 1 according to the present embodiment, air flows into the cavity 15 of the tubular member 10 from the first end portion 21, the first outer wall hole 40a, and the second outer wall hole 40b. Therefore, when air flows only from the first end portion 21 of the cylindrical member 10, that is, when air flows only along the axis AX direction, the flow of air toward the second filter wall 52 is reduced. Inside, the flow of air along only the direction of the axis AX is suppressed.
　また、第１外壁孔４０ａは、筒状部材１０の第２端部２２が下に位置するように軸線ＡＸ方向を鉛直方向Ｖｄに沿って向けた状態で、空洞１５に充填された香味源３０と隣接する位置に設けられる。 Further, the first outer wall hole 40a is a flavor source 30 filled in the cavity 15 in a state in which the axis AX direction is directed along the vertical direction Vd so that the second end 22 of the cylindrical member 10 is positioned below. Are provided at positions adjacent to each other.
　ここで、第２端部２２が下に位置するように軸線ＡＸ方向を鉛直方向Ｖｄに沿って向けた状態とは、香味源３０が最も第２フィルタ壁５２に密集した状態を模擬した状態である。つまり、第１外壁孔４０ａは、充填されている香味源３０が第２端部２２側に密集した状態を模擬した状態において、香味源３０と隣接する位置に設けられている。 Here, the state in which the axis AX direction is directed along the vertical direction Vd so that the second end portion 22 is positioned below is a state in which the flavor source 30 simulates a state in which the flavor source 30 is most closely packed on the second filter wall 52. is there. That is, the 1st outer wall hole 40a is provided in the position adjacent to the flavor source 30 in the state which simulated the state where the flavor source 30 with which it was filled closely to the 2nd edge part 22 side.
　上述した位置関係となるように、非加熱型香味吸引器１に第１外壁孔４０ａを設けることで、香味源３０が第２フィルタ壁５２に密集することをより確実に抑制できる。具体的には、第１外壁孔４０ａ１乃至４０ａ３を設けることにより、香味吸引時において、第１端部２１に由来する軸線ＡＸ方向のみに沿った空気の流れ以外にも、かかる軸線ＡＸ方向に交差する方向に沿った空気の流れが発生する。また、第１外壁孔４０ａ１乃至４０ａ３を設けることにより、第１外壁孔４０ａ１乃至４０ａ３に由来する空気の流れが支配的になり、その結果、香味源３０に与えられる空気の流れを、複数方向から与えることができる。これにより、香味吸引時において、香味源３０が第２フィルタ壁５２に密集することを抑制しうる。 It is possible to more reliably suppress the flavor source 30 from being concentrated on the second filter wall 52 by providing the first outer wall hole 40a in the non-heating type flavor inhaler 1 so as to have the positional relationship described above. Specifically, by providing the first outer wall holes 40a1 to 40a3, at the time of flavor suction, in addition to the air flow along only the axis AX direction derived from the first end portion 21, it intersects with the axis AX direction. A flow of air along the direction is generated. Further, by providing the first outer wall holes 40a1 to 40a3, the flow of air derived from the first outer wall holes 40a1 to 40a3 becomes dominant, and as a result, the flow of air given to the flavor source 30 is changed from a plurality of directions. Can be given. Thereby, it is possible to prevent the flavor source 30 from being concentrated on the second filter wall 52 at the time of flavor suction.
　言い換えると、従来技術では、軸線ＡＸ方向の空気の流れのみが発生していたため、第２フィルタ壁５２に香味源３０が急激に密集していたが、本実施形態では、上述のように、第１外壁孔４０ａ１乃至４０ａ３を設けることにより、軸線ＡＸ方向とは異なる方向に沿った空気の流れを発生させられることから、香味源３０が急激に密集することを効果的に抑制できる。 In other words, in the prior art, since only the air flow in the direction of the axis AX occurred, the flavor sources 30 were abruptly concentrated on the second filter wall 52, but in the present embodiment, as described above, the first By providing the 1 outer wall holes 40a1 to 40a3, it is possible to generate an air flow along a direction different from the direction of the axis AX, and thus it is possible to effectively suppress the concentration of the flavor sources 30 rapidly.
　このように、非加熱型香味吸引器１によれば、香味吸引開始時において、香味源３０の第２フィルタ壁５２への急激な移動や第２フィルタ壁５２近傍への急激な密集を抑制できる。 Thus, according to the non-heating type flavor inhaler 1, it is possible to suppress the rapid movement of the flavor source 30 to the second filter wall 52 and the rapid congestion near the second filter wall 52 at the start of flavor suction. .
　すなわち、非加熱型香味吸引器１によれば、香味吸引開始時において、香味源の移動によってユーザに与えられる違和感を抑制することができる。 That is, according to the non-heating type flavor inhaler 1, it is possible to suppress the uncomfortable feeling given to the user by the movement of the flavor source at the start of flavor suction.
　また、図３に示すように、第２フィルタ壁５２と、第１外壁孔４０ａとの軸線ＡＸ方向における距離Ｌｂは、０．５ｍｍ以上５．０ｍｍ以下の範囲内であることが好ましく、０．７ｍｍ以上２．０ｍｍ以下であることがより好ましい。 3, the distance Lb between the second filter wall 52 and the first outer wall hole 40a in the axis AX direction is preferably in the range of 0.5 mm or more and 5.0 mm or less. More preferably, it is 7 mm or more and 2.0 mm or less.
　ここで、筒状部材１０の空洞１５に流入する空気は、第１端部２１と第１外壁孔４０ａと第２外壁孔４０ｂとから流入するが、空洞１５に流入する空気の大半は、複数の第１外壁孔４０ａ１乃至４０ａ３の内、最も第２フィルタ壁５２側に位置する第１外壁孔４０ａ１から流入する。したがって、吸引時において、香味源３０による衝撃を緩和するためには、第１外壁孔４０ａは、なるべく第２フィルタ壁５２と近接させた位置に設けて、距離Ｌｂを小さくすることが好ましい。 Here, the air flowing into the cavity 15 of the tubular member 10 flows in from the first end portion 21, the first outer wall hole 40a, and the second outer wall hole 40b, but most of the air flowing into the cavity 15 is plural. Of the first outer wall holes 40a1 to 40a3, the first outer wall hole 40a1 is located closest to the second filter wall 52 side. Therefore, in order to reduce the impact caused by the flavor source 30 during suction, it is preferable to provide the first outer wall hole 40a as close to the second filter wall 52 as possible so as to reduce the distance Lb.
　一方、第１外壁孔４０ａと第２フィルタ壁５２との距離を一定以上に保つことで、第１外壁孔４０ａから第２フィルタ壁５２に流れる空気と香味源３０とが効果的に接触できる。その結果、好適な量の香味を、口腔内に供給することができる。したがって、本実施形態において、距離Ｌｂは、０．５ｍｍ以上であることが好ましい。 On the other hand, the air flowing from the first outer wall hole 40a to the second filter wall 52 and the flavor source 30 can effectively contact each other by keeping the distance between the first outer wall hole 40a and the second filter wall 52 at a certain level or more. As a result, a suitable amount of flavor can be supplied into the oral cavity. Therefore, in this embodiment, it is preferable that the distance Lb is 0.5 mm or more.
　また、距離Ｌｂが５．０ｍｍ以下であれば、第１端部２１から流入する空気と、第１外壁孔４０ａから流入する空気とが、第２フィルタ壁５２から離れた位置で合流せずに、軸線ＡＸ方向に交差する方向に流れる空気を第２フィルタ壁５２付近で発生し易くなり、軸線ＡＸ方向のみに沿った空気の流れをより確実に低下させることが可能になる。すなわち、第２フィルタ壁５２に集束する空気の流れを効果的に分散させるためには、距離Ｌｂが５．０ｍｍ以下であることが好ましい。 If the distance Lb is 5.0 mm or less, the air flowing in from the first end portion 21 and the air flowing in from the first outer wall hole 40a do not merge at a position away from the second filter wall 52. The air flowing in the direction intersecting the axis AX direction is likely to be generated in the vicinity of the second filter wall 52, and the air flow along only the axis AX direction can be more reliably reduced. That is, in order to effectively disperse the air flow focused on the second filter wall 52, the distance Lb is preferably 5.0 mm or less.
（４）比較評価１
　次に、本実施形態に係る非加熱型香味吸引器の比較評価について説明する。まず、実施例１乃至２に係る非加熱型香味吸引器と、比較例１に係る非加熱型香味吸引器とを準備した。 (4) Comparative evaluation 1
Next, comparative evaluation of the non-heating type flavor inhaler according to the present embodiment will be described. First, the non-heating type flavor inhaler according to Examples 1 and 2 and the non-heating type flavor inhaler according to Comparative Example 1 were prepared.
　実施例１として、図１及び図２に示す形状の非加熱型香味吸引器を作製した。具体的には、筒状部材１０としてプラスチックの成形体を用い、第１フィルタ壁５１及び第２フィルタ壁５２としてメッシュ部材を用いた。なお、筒状部材１０は鉛直方向（ＡＸ方向）に４２ｍｍの長さを円筒形状の外壁１１及び、鉛直方向に各々４ｍｍの長さを有する突出部２１ａ及び２２ａを有している。また、香味源としては、たばこ葉を成形したたばこ粉粒を用いた。第２端部２２が鉛直方向の下になるように静置した際に、第２フィルタ壁５２から香味源の上端までの距離が２５ｍｍとなるように、香味源を充填した。 As Example 1, an unheated flavor inhaler having the shape shown in FIGS. 1 and 2 was produced. Specifically, a plastic molded body was used as the cylindrical member 10, and mesh members were used as the first filter wall 51 and the second filter wall 52. The cylindrical member 10 includes a cylindrical outer wall 11 having a length of 42 mm in the vertical direction (AX direction) and protrusions 21a and 22a each having a length of 4 mm in the vertical direction. Moreover, the tobacco powder grain which shape | molded the tobacco leaf was used as a flavor source. The flavor source was filled so that the distance from the second filter wall 52 to the upper end of the flavor source was 25 mm when the second end portion 22 was left to stand below the vertical direction.
　また、実施例１では、筒状部材１０上に複数の第１外壁孔４０ａと複数の第２外壁孔４０ｂとを設けた。また、複数の第１外壁孔４０ａのうち第２フィルタ壁５２との距離が最も近い第１外壁孔４０ａ１（以下、直近の第１外壁孔４０ともいう）と、第２フィルタ壁５２との距離Ｌｂが１．０ｍｍとなるように、直近の第１外壁孔４０ａ１を筒状部材１０に形成した。また、直近の第１外壁孔４０ａ１を形成すると同時に、当該直近の第１外壁孔４０ａ１から第１フィルタ壁５１の直前まで、筒状部材１０の軸線ＡＸ方向に沿って、直近の第１外壁孔４０ａ１以外の複数の第１外壁孔４０ａと複数の第２外壁孔４０ｂとを形成した。複数の第１外壁孔４０ａと複数の第２外壁孔４０ｂとのそれぞれは、孔の中心間の距離（ピッチ）が、２．０ｍｍの間隔を有するように設けた。このようにして、複数の第１外壁孔４０ａと複数の第２外壁孔４０ｂを筒状部材１０の所定領域に１列設けた。同様に、複数の第１外壁孔４０ａと複数の第２外壁孔４０ｂは、筒状部材１０の軸線ＡＸを基準として、筒状部材１０の外壁１１の反対側にも、更に１列設けた。即ち、実施例１の非加熱型香味吸引器は、複数の第１外壁孔４０ａと複数の第２外壁孔４０ｂを２列有している。なお、複数の第１外壁孔４０ａと複数の第２外壁孔４０ｂの各々の直径（孔径）は０．５ｍｍとした。 In Example 1, a plurality of first outer wall holes 40a and a plurality of second outer wall holes 40b were provided on the tubular member 10. In addition, the distance between the first outer wall hole 40a1 (hereinafter also referred to as the nearest first outer wall hole 40) closest to the second filter wall 52 and the second filter wall 52 among the plurality of first outer wall holes 40a. The nearest first outer wall hole 40a1 was formed in the tubular member 10 so that Lb was 1.0 mm. Further, at the same time when the nearest first outer wall hole 40a1 is formed, the nearest first outer wall hole along the axis AX direction of the tubular member 10 extends from the nearest first outer wall hole 40a1 to immediately before the first filter wall 51. A plurality of first outer wall holes 40a and a plurality of second outer wall holes 40b other than 40a1 were formed. Each of the plurality of first outer wall holes 40a and the plurality of second outer wall holes 40b was provided such that the distance (pitch) between the centers of the holes had an interval of 2.0 mm. In this way, a plurality of first outer wall holes 40 a and a plurality of second outer wall holes 40 b are provided in a predetermined region of the tubular member 10. Similarly, the plurality of first outer wall holes 40 a and the plurality of second outer wall holes 40 b are further provided in a row on the opposite side of the outer wall 11 of the cylindrical member 10 with respect to the axis AX of the cylindrical member 10. That is, the non-heating type flavor inhaler of Example 1 has two rows of a plurality of first outer wall holes 40a and a plurality of second outer wall holes 40b. In addition, each diameter (hole diameter) of the some 1st outer wall hole 40a and the some 2nd outer wall hole 40b was 0.5 mm.
　また、実施例２として、直近の第１外壁孔４０ａ１の位置を、第２フィルタ壁５２からの距離Ｌｂが１０．０ｍｍとなるように変更した非加熱型香味吸引器を生製した。なお、実施例２は、距離Ｌｂの構成以外は、実施例１と同様の構成を有する。 Further, as Example 2, an unheated flavor inhaler was produced by changing the position of the nearest first outer wall hole 40a1 so that the distance Lb from the second filter wall 52 was 10.0 mm. In addition, Example 2 has the same configuration as that of Example 1 except for the configuration of the distance Lb.
　また、比較例１として、第１外壁孔４０ａと第２外壁孔４０ｂを形成していない非加熱型香味吸引器を生製した。なお、比較例１は、第１外壁孔４０ａと第２外壁孔４０ｂを形成しなかったこと以外は、実施例１と同様の構成を有する。 Further, as Comparative Example 1, a non-heated flavor suction device in which the first outer wall hole 40a and the second outer wall hole 40b were not formed was produced. Note that Comparative Example 1 has the same configuration as that of Example 1 except that the first outer wall hole 40a and the second outer wall hole 40b are not formed.
（通気抵抗の測定）
　ＩＳＯ ６５６５ - １９９７ Ｄｒａｗ ｒｅｓｉｓｔａｎｃｅ ｏｆ ｃｉｇａｒｅｔｔｅｓ ａｎｄ ｐｒｅｓｓｕｒｅ ｄｒｏｐ ｏｆ ｆｉｌｔｅｒ ｒｏｄｓに準拠した方法を用い、上記した実施例１、２及び比較例１の非加熱型香味吸引器の通気抵抗を測定した。具体的には、流れる空気の上流側から見て、非加熱型香味吸引器、差圧計、マスフローコントローラ、真空ポンプの順に装置をそれぞれ接続した。そして、真空ポンプで１０５０ｍｌ／ｓｅｃで吸引し、それぞれの非加熱型香味吸引器の通気抵抗を測定した。測定結果を表１に示す。 (Measurement of ventilation resistance)
Using the method according to ISO 6565-1997 Draw resistance of cigarettes and pressure drop of filter rods, the ventilation resistance of the non-heated flavor inhalers of Examples 1 and 2 and Comparative Example 1 was measured. Specifically, when viewed from the upstream side of the flowing air, the devices were connected in the order of a non-heated flavor suction device, a differential pressure gauge, a mass flow controller, and a vacuum pump. And it attracted | sucked with 1050 ml / sec with the vacuum pump, and the ventilation resistance of each non-heating type flavor suction device was measured. The measurement results are shown in Table 1.
（吸引時の衝撃に関する官能評価）
　上記した実施例１、２及び比較例１の香味吸引器を用いて、評価者２０人に対して香味吸引動作を実施させて、各々の非加熱型香味吸引器に対する官能評価試験を行った。具体的には、非加熱型香味吸引動作時の香味源に由来する衝撃を評価する官能評価試験を行った。結果を表１に示す。 (Sensory evaluation of impact during suction)
Using the flavor inhalers of Examples 1 and 2 and Comparative Example 1 described above, a flavor suction operation was performed on 20 evaluators, and a sensory evaluation test was performed on each non-heated type flavor inhaler. Specifically, a sensory evaluation test was performed to evaluate the impact derived from the flavor source during the non-heating type flavor suction operation. The results are shown in Table 1.
Figure JPOXMLDOC01-appb-T000001
Figure JPOXMLDOC01-appb-T000001
 　上記表１の評価結果からも明らかなように、比較例１においては衝撃が気になると答えた評価者が多数である一方、実施例１及び２においては、衝撃が気にならないと答えた評価者が多数となった。このように、実施例１及び２においては、比較例１に比べて、衝撃に起因する違和感を抑制する効果に優れていることが証明された。また、実施例１は、実施例２に比べて、吸引動作時の衝撃に起因する違和感をより効果的に抑制できていることが証明された。 As is clear from the evaluation results of Table 1 above, there are a large number of evaluators who answered that the impact was anxious in Comparative Example 1, whereas in Examples 1 and 2, the evaluation was that the impact was not anxious. The number of people became large. Thus, in Examples 1 and 2, it was proved that the effect of suppressing the uncomfortable feeling caused by the impact was superior to that of Comparative Example 1. In addition, it was proved that Example 1 was able to more effectively suppress the uncomfortable feeling caused by the impact during the suction operation compared to Example 2.
　なお、通気抵抗測定の結果からも明らかなように、第１及び第２のフィルタ壁としてメッシュを用いた場合、第１外壁孔４０ａと第２外壁孔４０ｂとを有する非加熱型香味吸引器は、１５．０ｍｍＨ２Ｏ以下の通気抵抗を有することがわかる。 As is apparent from the results of the ventilation resistance measurement, when mesh is used as the first and second filter walls, the non-heating type flavor inhaler having the first outer wall hole 40a and the second outer wall hole 40b is It can be seen that it has a ventilation resistance of 15.0 mmH 2 O or less.
（吸引動作時の通気抵抗変動測定）
　続いて、実施例１の非加熱型香味吸引器及び比較例１の非加熱型香味吸引器とを用い、各非加熱型香味吸引器における吸引動作時における通気抵抗の変化を測定した。 (Measurement of ventilation resistance fluctuation during suction operation)
Then, the non-heating type flavor suction device of Example 1 and the non-heating type flavor suction device of the comparative example 1 were used, and the change of ventilation resistance at the time of suction operation in each non-heating type flavor suction device was measured.
　まず、試験装置を準備した。具体的には、真空ポンプ（ｌｉｎｉｃｏｎ　ｌｖ６６０　日東工器社製）と香味吸引器の間に、マスフローコントローラ（ＳＥＣ－Ｂ４０　堀場エステック社製）、電磁弁（ＡＧ－４３－０２－４　ＣＤＫ社製）、差圧計（ＤＰ４５－２８　ｖａｌｉｄｙｉｎｅ　ｅｎｇｉｎｅｅｒｉｎｇ　ｃｏｒｐｏｒａｔｉｏｎ製）を真空ポンプ側（系の下流側）から順に配設し、差圧計とデータロガー（ＮＲ６００　キーエンス社製）及びＰＣを接続することで、通気抵抗の経時変化が可視化できるような試験装置を作製した。 First, a test device was prepared. Specifically, a mass flow controller (SEC-B40, manufactured by HORIBA STEC), a solenoid valve (AG-43-02-4, manufactured by CDK) between the vacuum pump (linicon lv660, manufactured by Nitto Kohki Co., Ltd.) and the flavor suction device , Differential pressure gauge (DP45-28 validine engineering corporation) is arranged in order from the vacuum pump side (downstream side of the system), and by connecting the differential pressure gauge, data logger (NR600 Keyence Corporation) and PC, the ventilation resistance A test apparatus that can visualize changes with time was prepared.
　また、試験装置の電磁弁を閉めた状態、即ち、各非加熱型香味吸引器から真空ポンプへの空気流入を抑えた状態において、真空ポンプの空気吸引の出力を５Ｌ／ｍｉｎで安定するように調節した。その後、電磁弁を解放することで、香味吸引器からの空気吸引を行った。この時、差圧計を用い、空気吸引直後の通気抵抗の経時変化を測定した。測定結果を図４に示す。 In addition, in a state where the electromagnetic valve of the test apparatus is closed, that is, in a state where air inflow from each non-heated flavor suction device to the vacuum pump is suppressed, the air suction output of the vacuum pump is stabilized at 5 L / min. Adjusted. Thereafter, air was sucked from the flavor suction device by releasing the electromagnetic valve. At this time, using a differential pressure gauge, the change in ventilation resistance with time immediately after air suction was measured. The measurement results are shown in FIG.
　図４からも明らかなように、比較例１の非加熱型香味吸引器においては、吸引開始から０．１秒以内に、通気抵抗の大きな減少及び係る減少の回復挙動が見られる。一方、実施例１の非加熱型香味吸引器においてはこのような通気抵抗の大きな変動等は無く、吸引開始直後から極めて安定した通気抵抗を示していることがわかる。香味源に由来する衝撃は吸引開始直後に生じるため、係る通気抵抗の経時変化の違いが上記した官能評価の結果の違いを導き出したといえる。即ち、本発明は吸引開始後０．１秒以内という、極めて短い時間の間において、通気抵抗の変動量を抑制する効果に優れていることが証明された。 As is clear from FIG. 4, in the non-heated flavor inhaler of Comparative Example 1, a large decrease in ventilation resistance and a recovery behavior of the decrease are observed within 0.1 second from the start of suction. On the other hand, in the non-heating type flavor inhaler of Example 1, there is no such large fluctuation | variation of ventilation resistance, etc., and it turns out that very stable ventilation resistance is shown immediately after the suction start. Since the impact derived from the flavor source occurs immediately after the start of suction, it can be said that the difference in the temporal change in the ventilation resistance led to the difference in the results of the sensory evaluation described above. That is, it has been proved that the present invention is excellent in the effect of suppressing the fluctuation amount of the ventilation resistance within an extremely short time of 0.1 seconds after the start of suction.

　次に、比較例２として、第１フィルタ壁と第２フィルタ壁とにアセテートフィルタを用いた非加熱型香味吸引器を作製した。比較例２は、第１フィルタ壁と第２フィルタ壁との構成以外は、上述した比較例１と同様の構成を有する。 Next, as Comparative Example 2, a non-heated flavor inhaler using an acetate filter for the first filter wall and the second filter wall was produced. Comparative Example 2 has the same configuration as Comparative Example 1 described above except for the configuration of the first filter wall and the second filter wall.
　なお、実施例３乃至４と比較例２では、第１及び第２フィルタ壁に用いたアセテートフィルタは、いずれも非加熱型香味吸引器の軸線ＡＸ方向に対して５ｍｍの厚みを有するものを用いた。 In Examples 3 to 4 and Comparative Example 2, the acetate filters used for the first and second filter walls both have a thickness of 5 mm with respect to the axis AX direction of the non-heated flavor inhaler. It was.
（吸引時の衝撃に関する官能評価）
　上記した実施例３、４及び比較例２の香味吸引器を用いて、評価者２０人に対して香味吸引動作を実施させて、各々の非加熱型香味吸引器に対する官能評価試験を行った。具体的には、非加熱型香味吸引動作時の香味源に由来する衝撃を評価する官能評価試験を行った。結果を表２に示す。 (Sensory evaluation of impact during suction)
Using the flavor inhalers of Examples 3 and 4 and Comparative Example 2 described above, 20 evaluators were allowed to perform a flavor suction operation, and a sensory evaluation test was performed on each non-heated flavor inhaler. Specifically, a sensory evaluation test was performed to evaluate the impact derived from the flavor source during the non-heating type flavor suction operation. The results are shown in Table 2.

　上記表２の結果からも明らかなように、第１及び第２のフィルタ壁として、アセテートフィルタを用いた場合においても、実施例３及び４では、吸引動作時の衝撃を極めて効果的に低減することが証明された。すなわち、第１外壁孔４０ａと第２外壁孔４０ｂとを有する非加熱型香味吸引器は、吸引動作時の衝撃を極めて効果的に低減することが証明された。また、実施例３は、実施例４に比べて、吸引動作時の衝撃に起因する違和感をより効果的に抑制できていることが証明された。なお、第１及び第２のフィルタ壁として、アセテートフィルタを用いた場合、第１外壁孔４０ａと第２外壁孔４０ｂとを有する非加熱型香味吸引器は、２５．０ｍｍＨ２Ｏ以下の通気抵抗を有することがわかる。 As is clear from the results of Table 2 above, even in the case where acetate filters are used as the first and second filter walls, in Examples 3 and 4, the impact during the suction operation is extremely effectively reduced. It was proved. That is, it has been proved that the non-heated flavor inhaler having the first outer wall hole 40a and the second outer wall hole 40b extremely effectively reduces the impact during the suction operation. In addition, it was proved that Example 3 was able to more effectively suppress the uncomfortable feeling caused by the impact during the suction operation compared to Example 4. In addition, when an acetate filter is used as the first and second filter walls, the non-heated flavor inhaler having the first outer wall hole 40a and the second outer wall hole 40b has a ventilation resistance of 25.0 mmH 2 O or less. It can be seen that
