Further, the arrangement of the plurality of second opening portions 18 is the same as the arrangement of the plurality of first opening portions 17. That is, as shown in FIG. 2, the plurality of second opening portions 18 are displaced from each other in the direction of the axis C and are also displaced from each other in the circumferential direction R of the second cover portion 16. For this reason, the plurality of second apertures 18 are displaced from each other stepwise.

　フィルター本体２２は、様々な種類の充填材によって形成できる。本実施形態において、フィルター本体２２は、例えば、セルロースアセテートなどのセルロース系半合成繊維の充填材で構成されるが、充填材としてはこれに限定されない。充填材は、例えば、綿、麻、マニラ麻、ヤシ、イグサなどの植物繊維、羊毛、カシミヤなどの動物繊維、レーヨンなどのセルロース系再生繊維、ナイロン、ポリエステル、アクリル、ポリエチレン、ポリプロピレンなどの合成繊維あるいはそれらを組合せたものを使用することができる。フィルター部の構成要素は、上記のセルロースアセテート繊維からなる充填物の他、チャコールを含んだチャコールフィルターやチャコール以外の粒状物が入ったフィルターでもよい。また、フィルター部は、異なる種類のセグメントを軸方向に２つ以上連接したマルチセグメント構造としても良い。その際は、各セグメントは巻取物２３で周囲を巻かれてフィルター部１３での位置が固定される。個々のセグメントは、それぞれの充填材がセグメント用巻取材で巻かれていても良いし、日本の特許第４２６２２４７号の図１５にあるようなノンラップフィルターを用いても良い。 The filter body 22 can be formed by various kinds of fillers. In the present embodiment, the filter body 22 is composed of a filler of cellulose semisynthetic fibers such as cellulose acetate, but the filler is not limited to this. Fillers include, for example, plant fibers such as cotton, hemp, manila hemp, palm and rush, animal fibers such as wool and cashmere, cellulosic regenerated fibers such as rayon, synthetic fibers such as nylon, polyester, acrylic, polyethylene and polypropylene, or A combination of them can be used. The constituent element of the filter part may be a charcoal filter containing charcoal or a filter containing a granular material other than charcoal, in addition to the above-mentioned filler made of cellulose acetate fiber. The filter unit may have a multi-segment structure in which two or more different types of segments are connected in the axial direction. In that case, each segment is wound around the wound material 23 and the position on the filter unit 13 is fixed. In each segment, each filler may be wound with a winding material for a segment, or a non-wrap filter as shown in FIG. 15 of Japanese Patent No. 4262247 may be used.
　また、フィルター部１３のフィルター本体２２には、フィルター部１３を所望の硬さとするために、可塑剤およびバインダーの少なくとも一方を添加しても良い。使用する可塑剤の種類は問わない。例えば、可塑剤として、クエン酸トリエチル、クエン酸アセチル・トリエチル、クエン酸アセチル・トリブチル、酒石酸ジブチル、エチルフタリル・エチルグリコレート、メチルフタリル・エチルグリコレート、トリアセチン、りん酸トリエチル、りん酸トリフェニル、トリプロピオニンあるいはそれらを組合せたものを使用することができる。使用するバインダーの種類は問わない。例えば、バインダーとして、HMC、HPMC、PVA、PVAｃ、PEG、あるいはそれらを組み合わせたものを使用することができる。場合により可塑剤およびバインダーを使用しなくても良い。 Further, at least one of a plasticizer and a binder may be added to the filter main body 22 of the filter unit 13 in order to make the filter unit 13 have a desired hardness.

The kind of binder to be used is not limited. For example, HMC, HPMC, PVA, PVAc, PEG, or a combination thereof can be used as the binder. In some cases, a plasticizer and a binder may not be used.
　また、フィルター本体２２には、メンソールなどのフレーバを含んでもよい。フレーバの加香方法は特に問わないが、例えばフレーバを吸着させたひも状の物質をフィルター本体内に配置する、あるいはフィルター部１３の充填物にフレーバを含ませる、あるいはカプセルなどのフレーバを固定化した材料をフィルター部に配置する方法でもよい。フィルター部のフィルター本体２２に使用する巻取物２３（巻取紙）の種類および材質は問わない。巻取物２３は、一般的なシガレット用フィルターに使用される巻取紙を用いることができて、通気性を有した巻取紙でも良いし、通気性を有しないものでも良い。巻取物２３の通気性は、第１覆い部１５と第２覆い部１６との隙間から導入される希釈空気の量に影響を与えるので、所望される第１覆い部１５と第２覆い部１６との隙間から導入される希釈空気の量に応じて巻取物２３の通気性を適宜選定できる。一般的な製品に使用される巻取紙は、坪量が２０～１００[g/m2]、厚さが３０～１１０[μm]、通気性が、0～３００００[コレスタユニット]である。巻取物２３の材質には、一般的には植物性の繊維で作製された紙が用いられるが、ポリマー系（ポリプロピレン、ポリエチレン、ナイロンなど）の化学繊維を用いた不織布またはポリマー系（セルロース、セルロースアセテート、ポリプロピレン、ポリエチレン、ナイロン、ポリ乳酸など）のフィルムが用いられても良いし、アルミ箔のような金属箔が用いられてもよい。 Also, the filter body 22 may include a flavor such as menthol. The flavoring method is not particularly limited. For example, a string-like substance adsorbing the flavor is disposed in the filter body, or the filler in the filter portion 13 is included, or the flavor such as a capsule is fixed. It is also possible to use a method in which the obtained material is arranged in the filter part. The type and material of the wound material 23 (winding paper) used for the filter main body 22 of the filter portion are not limited. The wound material 23 may be a wound paper used for a general cigarette filter, and may be a wound paper having air permeability or may not have air permeability. The air permeability of the wound article 23 affects the amount of dilution air introduced from the gap between the first cover 15 and the second cover 16, and therefore the desired first cover 15 and second cover The air permeability of the wound product 23 can be selected as appropriate according to the amount of diluted air introduced from the gap with 16. A web used for a general product has a basis weight of 20 to 100 [g / m 2], a thickness of 30 to 110 [μm], and an air permeability of 0 to 30000 [Cholesta unit]. As the material of the wound material 23, paper made of vegetable fiber is generally used. However, a non-woven fabric or polymer system (cellulose, cellulose, etc.) using chemical fibers (polypropylene, polyethylene, nylon, etc.) is used. A film of cellulose acetate, polypropylene, polyethylene, nylon, polylactic acid, etc.) may be used, or a metal foil such as an aluminum foil may be used.
　一般的な製品に使用されるチップペーパー（第１覆い部１５、第２覆い部１６）は、坪量が35～56[g/m2]、厚さが35～45[μm]の紙であり、表面にブランドロゴ等の印刷を施しやすくするための平滑性を有していて、フィルター部が透けて見えないように二酸化チタン、炭酸カルシウム等の充填材を配合して不透明度をあげても良い。チップペーパー（第１覆い部１５、第２覆い部１６）の材質は問わない。チップペーパーには一般的には植物性の繊維で作製された紙が用いられるが、ポリマー系（ポリプロピレン、ポリエチレン、ナイロンなど）の化学繊維を用いた不織布またはポリマー系（セルロース、セルロースアセテート、ポリプロピレン、ポリエチレン、ナイロン、ポリ乳酸など）のフィルムを使用してもよいし、アルミ箔のような金属箔を用いてもよい。 Chip paper (first cover 15 and second cover 16) used for general products is paper with a basis weight of 35 to 56 [g / m2] and a thickness of 35 to 45 [μm]. Even if it has smoothness to make it easy to print brand logos on the surface, it can be made opaque by adding fillers such as titanium dioxide and calcium carbonate so that the filter part can not be seen through good. The material of chip paper (the 1st cover part 15 and the 2nd cover part 16) is not ask | required. In general, paper made of vegetable fiber is used for chip paper, but non-woven fabric or polymer type (cellulose, cellulose acetate, polypropylene, etc.) using chemical fibers of polymer type (polypropylene, polyethylene, nylon, etc.) A film of polyethylene, nylon, polylactic acid, etc.) or a metal foil such as an aluminum foil may be used.
　第１覆い部１５と第２覆い部１６との間の間隙は、極めて小さい寸法となるように調整されている。このため、この間隙からフィルター部１３内に導入される空気量は、ごく少量である。なお、シガレット１１において、通気性が無いか、あったとしても比較的に低い巻取物２３を採用することができる。これによって、上記間隙からフィルター部１３内に少量の外気が導入されたとしても、当該外気によって主流煙が必要以上に薄められてしまうことがない。一方、逆に上記間隙を利用して、通気性が比較的高い巻取物２３を使用することで、積極的にフィルター部１３内に外気（空気）を取り込んで、主流煙を薄めることもできる。 The gap between the first cover portion 15 and the second cover portion 16 is adjusted to have a very small size. For this reason, the amount of air introduced into the filter unit 13 from this gap is very small. In addition, in the cigarette 11, the winding material 23 with a comparatively low even if there is no air permeability can be employ | adopted. Thereby, even if a small amount of outside air is introduced into the filter unit 13 from the gap, the mainstream smoke is not diluted more than necessary by the outside air. On the other hand, by using the wound material 23 having a relatively high air permeability by using the gap, it is possible to actively take outside air (air) into the filter portion 13 and dilute mainstream smoke. .
　図４、図５等を参照して、本実施形態のシガレット１１の作用について説明する。本実施形態では、喫煙者がシガレット１１の煙の濃度を変更したいと思う場合に、フィルター部１３の煙草部側部分１３Ａに対して吸口側部分１３Ｂを回転させる（第１覆い部１５に対して第２覆い部１６を回転させる）ことで、煙の濃度を濃くしたり薄くしたりすることができる。 The operation of the cigarette 11 of the present embodiment will be described with reference to FIGS. In the present embodiment, when the smoker wants to change the smoke concentration of the cigarette 11, the suction side portion 13B is rotated with respect to the tobacco portion side portion 13A of the filter portion 13 (with respect to the first cover portion 15). By rotating the second cover 16, the smoke concentration can be increased or decreased.
　図４に示すように、シガレット１１を包装箱から取り出した状態では、例えば、第１開孔部１７の第１部分１７Ａは、第１開孔部１７の第２部分１７Ｂに対して第２覆い部１６の円周方向Ｒに位置ずれした第１位置Ｐ１に配置している。この第１位置Ｐ１では、第２開孔部１８の第３部分１８Ａは、第２開孔部１８の第４部分１８Ｂに対して第２覆い部１６の円周方向Ｒに位置ずれしている。喫煙者は、このままの状態でも、煙草部１２の先端に点火をして吸口２４から吸引をすることで、濃度の濃い煙による濃厚な香喫味を楽しむことができる。 As shown in FIG. 4, in the state where the cigarette 11 is removed from the packaging box, for example, the first portion 17 </ b> A of the first opening portion 17 covers the second portion 17 </ b> B of the first opening portion 17. The portion 16 is disposed at a first position P1 that is displaced in the circumferential direction R. In the first position P1, the third portion 18A of the second aperture 18 is displaced in the circumferential direction R of the second cover portion 16 with respect to the fourth portion 18B of the second aperture 18. . Even in this state, the smoker can enjoy a rich savory taste due to dense smoke by igniting the tip of the cigarette part 12 and sucking it from the suction port 24.
　喫煙者は、フィルター部１３の煙草部側部分１３Ａに対して吸口側部分１３Ｂおよび第２覆い部１６を回転させることで、上記した第１位置Ｐ１から、第１開孔部１７の第１部分１７Ａが第１開孔部１７の第２部分１７Ｂに対して整合した第２位置Ｐ２に移動できる。この第２位置Ｐ２では、第２開孔部１８の第３部分１８Ａが第２開孔部１８の第４部分１８Ｂに対して整合する。本実施形態では、図４に示すように、吸口２４側からみて、吸口側部分１３Ｂおよび第２覆い部１６を反時計回り方向（図４中の矢印の方向）に例えば約１５０°回転させることで、図４に示す第１位置Ｐ１から図５に示す第２位置Ｐ２に移動させることができる。この状態では、図５に矢印で示すように、複数の第１開孔部１７および複数の第２開孔部１８を介してフィルター部１３内に積極的に空気を取り込むことができる。これによって、フィルター部１３内を流れる煙が薄められ、喫煙者は、濃度が比較的に低い煙によるあっさりとした香喫味（軽い吸い口の香喫味）を楽しむことができる。 The smoker rotates the suction side portion 13B and the second cover portion 16 with respect to the cigarette portion side portion 13A of the filter portion 13, whereby the first portion of the first opening portion 17 from the first position P1 described above. 17A can move to the second position P2 aligned with the second portion 17B of the first opening 17. In the second position P2, the third portion 18A of the second opening 18 is aligned with the fourth portion 18B of the second opening 18. In the present embodiment, as shown in FIG. 4, the suction side portion 13 </ b> B and the second cover 16 are rotated counterclockwise (in the direction of the arrow in FIG. 4), for example, by about 150 ° as viewed from the suction port 24 side. Thus, the first position P1 shown in FIG. 4 can be moved to the second position P2 shown in FIG. In this state, as indicated by arrows in FIG. 5, air can be actively taken into the filter portion 13 through the plurality of first opening portions 17 and the plurality of second opening portions 18. As a result, the smoke flowing through the filter unit 13 is diluted, and the smoker can enjoy a light savory taste (light taste of the light mouthpiece) due to the smoke having a relatively low concentration.
　このように第２位置Ｐ２にある状態では、第１開孔部１７および第２開孔部１８から取り入れられた空気が主流煙中で占める割合は、例えば６０～８０％の高い数値をとることができる。このように、高い通気度を実現できれば、主流煙を低タール化することが容易になる。また、喫煙者は、第１位置Ｐ１から第２位置Ｐ２にするために、約１５０°という大きい角度分だけ吸口側部分１３Ｂを回転できる構造となるため、嗜好品として喫煙者の興味をそそる構造が実現される。なお、第１覆い部１５または第２覆い部１６には、吸口側部分１３Ｂおよび第２覆い部１６の回転方向を示す指標（表示）が設けられていることが好ましい。 As described above, in the state at the second position P2, the ratio of the air taken in from the first opening portion 17 and the second opening portion 18 in the mainstream smoke is a high value of, for example, 60 to 80%. Can do. Thus, if high air permeability can be realized, it becomes easy to lower the mainstream smoke. In addition, since the smoker has a structure capable of rotating the mouth side portion 13B by a large angle of about 150 ° in order to change from the first position P1 to the second position P2, a structure that intrigues the smoker as a favorite item. Is realized. In addition, it is preferable that the 1st cover part 15 or the 2nd cover part 16 is provided with the parameter | index (display) which shows the rotation direction of the inlet-side part 13B and the 2nd cover part 16. FIG.
　一方、喫煙者は、予め上記第２位置Ｐ２にした状態で煙草部１２の先端に点火をすることで、当初から軽快な香喫味を味わうこともできる。また、喫煙者は、このように軽い吸い口を楽しんでいる途中で、濃度の濃い煙を味わいたくなった場合には、フィルター部１３の煙草部側部分１３Ａに対して吸口側部分１３Ｂを、吸口２４側からみて時計回り方向に例えば１５０°回転させることで、第２位置Ｐ２から第１位置Ｐ１に戻すことができる。これによって、喫煙者は、濃厚な吸い口の煙を味わうこともできる。 On the other hand, the smoker can taste a light savory taste from the beginning by igniting the tip of the tobacco part 12 in the state where the second position P2 is set in advance. In addition, in the middle of enjoying a light mouthpiece as described above, when a smoker wants to taste smoke with a high concentration, the mouthpiece side portion 13B with respect to the tobacco portion side portion 13A of the filter portion 13, By rotating, for example, 150 ° in the clockwise direction when viewed from the inlet 24 side, the second position P2 can be returned to the first position P1. Thereby, the smoker can also taste the smoke from the mouthpiece.
　さらに、喫煙者は、第２位置Ｐ２の状態から吸口側部分１３Ｂおよび第２覆い部１６を若干の角度分だけ回転させることで、複数の第１開孔部１７の第２部分１７Ｂに対して、複数の第１開孔部１７の第１部分１７Ａが一部だけオーバーラップした状態にすることができる。この状態では、複数の第２開孔部１８の第４部分１８Ｂに対して、複数の第２開孔部１８の第３部分１８Ａが一部だけオーバーラップした状態となる。これによって、第１位置Ｐ１にあるときと、第２位置Ｐ２にあるときと、の中間程度の通気度に調整することもできる。 Further, the smoker rotates the suction side portion 13B and the second cover portion 16 by a slight angle from the state of the second position P2, thereby making the second portion 17B of the plurality of first opening portions 17 with respect to the second portion 17B. The first portions 17A of the plurality of first opening portions 17 can be partially overlapped. In this state, the third portions 18A of the plurality of second opening portions 18 partially overlap the fourth portions 18B of the plurality of second opening portions 18. Thereby, it is possible to adjust the air permeability to an intermediate level between the first position P1 and the second position P2.
　続いて、本実施形態のシガレット１１の製造工程について説明する。まず、一般的な方法によって煙草部１２（巻き）と２本分の長さのフィルター部１３とを製造する。そして、２本の煙草部１２の間に２本分の長さのフィルター部１３を挿入する。このフィルター部１３には、予め円盤状のカッター等を用いて、切れ込み部２５の内側に回転部２１が形成されている。さらに、第１覆い部１５、第２覆い部１６、第１覆い部１５の順番で並べた覆い部（チップペーパー）によって煙草部１２およびフィルター部１３を一括して巻き上げることで煙草部１２とフィルター部１３とを連結したロッド状のものを形成する。このとき、中央に位置する第２覆い部１６は、２本分のシガレット１１に対応する長さを有する。２枚の第１覆い部１５および第２覆い部１６には、巻上げ前に接着材が塗布される。 Then, the manufacturing process of the cigarette 11 of this embodiment is demonstrated. First, the cigarette part 12 (winding) and the filter part 13 having a length of two are manufactured by a general method. Then, a filter portion 13 having a length of two is inserted between the two tobacco portions 12. In this filter portion 13, a rotating portion 21 is formed on the inner side of the cut portion 25 using a disk-shaped cutter or the like in advance. Further, the cigarette part 12 and the filter part 13 are wound together by winding up the cigarette part 12 and the filter part 13 by a cover part (chip paper) arranged in the order of the first cover part 15, the second cover part 16, and the first cover part 15. The rod-shaped thing which connected the part 13 is formed. At this time, the second cover portion 16 located at the center has a length corresponding to two cigarettes 11. An adhesive is applied to the two first cover portions 15 and the second cover portion 16 before winding.
　そして、連結されたロッド状のものを所定速度で走行させながら、ＣＯ２レーザー等のレーザー発振器から出力された連続出力ビームを、回転チョッパー等を使って、該ロッドの外周方向からパルス状に分配して照射する。このパルス状のレーザー光によって、第２覆い部１６に対して複数の第１開孔部１７（第１部分１７Ａと第２部分１７Ｂの両方）および第２開孔部１８（第３部分１８Ａと第４部分１８Ｂの両方）を形成する。このとき、シガレット１１では、第１開孔部１７および第２開孔部１８の位置関係が第２位置Ｐ２となっており、第１部分１７Ａが第２部分１７Ｂに対して整合し、第３部分１８Ａが第４部分１８Ｂに対して整合している。そして、２本分の長さのフィルター部１３の中央の位置でカッターによってフィルター部１３および第２覆い部１６（チップペーパー）を切断して、１本のシガレット１１が製造される。また、シガレット１１は、上記した第２位置Ｐ２から、第１部分１７Ａと第２部分１７Ｂとが円周方向Ｒに位置ずれ（第３部分１８Ａと第４部分１８Ｂとが円周方向Ｒに位置ずれ）した第１位置Ｐ１に回転させた状態で、箱詰めされる。この第２位置Ｐ２から第１位置Ｐ１への回転作業は、上記したシガレット製造工程内において２本分の長さのフィルター部１３の中央の位置でカッターによってフィルター部１３および第２覆い部１６（チップペーパー）を切断して、１本のシガレット１１が製造された工程の後の工程に設けた回転機構を用いて行なっても良いし、人力で行っても良いし、箱詰め装置の一部に設けた回転機構を用いて自動的に行ってもよい。 Then, while driving the connected rod-shaped objects at a predetermined speed, the continuous output beam output from a laser oscillator such as a CO 2 laser is distributed in pulses from the outer periphery of the rod using a rotating chopper or the like. And then irradiate. By this pulsed laser beam, a plurality of first apertures 17 (both the first portion 17A and the second portion 17B) and a second aperture 18 (the third portion 18A) Both of the fourth portions 18B) are formed. At this time, in the cigarette 11, the positional relationship between the first opening portion 17 and the second opening portion 18 is the second position P2, the first portion 17A is aligned with the second portion 17B, and the third portion The portion 18A is aligned with the fourth portion 18B. And the filter part 13 and the 2nd cover part 16 (chip paper) are cut | disconnected with a cutter in the center position of the filter part 13 of two lengths, and the one cigarette 11 is manufactured. Further, in the cigarette 11, the first portion 17A and the second portion 17B are displaced in the circumferential direction R from the second position P2 described above (the third portion 18A and the fourth portion 18B are positioned in the circumferential direction R). The box is packed in a state of being rotated to the shifted first position P1. The rotation operation from the second position P2 to the first position P1 is performed by a cutter at the center position of the two filter portions 13 in the cigarette manufacturing process described above by the cutter 13 and the second cover portion 16 ( Chip paper) may be cut using a rotating mechanism provided in a process subsequent to the process of manufacturing one cigarette 11, or may be performed manually, or part of a boxing device. You may perform automatically using the provided rotation mechanism.
　なお、複数の第１開孔部１７および複数の第２開孔部１８の製造方法としては、上記に限定されない。例えば、通常のシガレット１１を製造したあとにＣＯ２レーザーにて複数の第１開孔部１７および複数の第２開孔部１８を設けてもよい。 In addition, as a manufacturing method of the some 1st opening part 17 and the some 2nd opening part 18, it is not limited above. For example, a plurality of first apertures 17 and a plurality of second apertures 18 may be provided with a CO 2 laser after the normal cigarette 11 is manufactured.

Next, the cigarettes 11 of Examples 1 to 4 and Comparative Examples 1 and 2 shown in the table of FIG. 6 will be described. In Example 1, the length of the long side of the 1st aperture part 17 and the 2nd aperture part 18 is 0.5 mm, and the length of the short side of the 1st aperture part 17 and the 2nd aperture part 18 is The length is 0.05 to 0.5 mm, although it depends on manufacturing variations. In Example 2, the lengths of the long sides of the first aperture 17 and the second aperture 18 are 1 mm, and the lengths of the short sides of the first aperture 17 and the second aperture 18 are The length is 0.05 to 0.5 mm depending on the manufacturing variation. In Example 3, the lengths of the long sides of the first aperture portion 17 and the second aperture portion 18 are 2 mm, and the lengths of the short sides of the first aperture portion 17 and the second aperture portion 18 are The length is 0.05 to 0.5 mm depending on the manufacturing variation. In Example 4, the lengths of the long sides of the first aperture portion 17 and the second aperture portion 18 are 3 mm, and the lengths of the short sides of the first aperture portion 17 and the second aperture portion 18 are The length is 0.05 to 0.5 mm depending on the manufacturing variation.
　比較例１では、第１開孔部１７および第２開孔部１８の長辺の長さは、４ｍｍであり、第１開孔部１７および第２開孔部１８の短辺の長さは、製造時のばらつきにより０．０５～０．５ｍｍの長さで形成される。比較例２では、第１開孔部１７および第２開孔部１８の長辺の長さは、８ｍｍであり、第１開孔部１７および第２開孔部１８の短辺の長さは、製造時のばらつきにより０．０５～０．５ｍｍの長さで形成される。 In Comparative Example 1, the lengths of the long sides of the first hole portion 17 and the second hole portion 18 are 4 mm, and the lengths of the short sides of the first hole portion 17 and the second hole portion 18 are The length is 0.05 to 0.5 mm depending on the manufacturing variation. In Comparative Example 2, the lengths of the long sides of the first hole portion 17 and the second hole portion 18 are 8 mm, and the lengths of the short sides of the first hole portion 17 and the second hole portion 18 are The length is 0.05 to 0.5 mm depending on the manufacturing variation.
　実施例１～４および比較例１、２のシガレット１１について、不良品の発生数について調査を行った。調査は、複数の第１開孔部１７を鉛直方向の上側、複数の第２開孔部１８を鉛直方向の下側に位置させ、この状態で吸口２４を喫煙者が口でくわえた状態を想定して、フィルター部１３の吸口２４近傍の位置に上下から圧力をかけた。これによって、フィルター部１３の吸口側部分１３Ｂの高さを通常の状態から３ｍｍ程度つぶした。この状態で、フィルター部１３の煙草部側部分１３Ａに対して吸口側部分１３Ｂを９０°回転させて、その状態で第２覆い部１６の浮き上がりの有無を目視で評価した。その結果、比較例１、２では、例えば図７に示すような、第１開孔部１７および第２開孔部１８の周囲で、第２覆い部１６の厚さ以上の浮き上がり（段差）を第２覆い部１６に生じるケースがあった。このように、第２覆い部１６の厚さ以上の浮き上がり（段差）を生じた場合には、チェック者は、不良品として判断した。上記の評価方法では、比較例１では、２０本当たり１３本の不良品を生じた。同様に、比較例２では、２０本のすべてが不良品と判断された。このような不良品では、喫煙者に対して外観不良の印象を持たせてしまう可能性があるし、第１開孔部１７および第２開孔部１８を介した通気量が設計値を超えて大きくなり、メーカーが予定した香喫味を喫煙者が味わうことができない。 The number of defective products was investigated for the cigarettes 11 of Examples 1 to 4 and Comparative Examples 1 and 2. In the investigation, the plurality of first apertures 17 are positioned on the upper side in the vertical direction, and the plurality of second apertures 18 are positioned on the lower side in the vertical direction. In this state, the smoker holds the mouthpiece 24 in the mouth. Assuming that pressure was applied to the position near the suction port 24 of the filter unit 13 from above and below. As a result, the height of the suction side portion 13B of the filter portion 13 was crushed by about 3 mm from the normal state. In this state, the suction side portion 13B was rotated by 90 ° with respect to the cigarette portion side portion 13A of the filter portion 13, and in this state, the presence or absence of lifting of the second cover portion 16 was visually evaluated. As a result, in the first and second comparative examples, for example, as shown in FIG. 7, there is a floating (step) higher than the thickness of the second cover portion 16 around the first opening portion 17 and the second opening portion 18. There was a case that occurred in the second cover portion 16. Thus, when the lift (step difference) more than the thickness of the 2nd cover part 16 produced, the checker judged as a defective article. In the evaluation method described above, in Comparative Example 1, 13 defective products were produced per 20 products. Similarly, in Comparative Example 2, all 20 pieces were determined to be defective. Such defective products may give the smoker an impression of poor appearance, and the amount of ventilation through the first opening 17 and the second opening 18 exceeds the design value. The smoker cannot enjoy the savory taste scheduled by the manufacturer.
　一方、実施例１～４では、例えば図８に示すように、第１開孔部１７の周囲で、第２覆い部１６の厚さ以上の浮き上がり（段差）を第２覆い部１６に生じることはなかった。なお、図８では、第２開孔部１８の図示を省略している。このように第２覆い部１６に浮き上がりを生じない場合には、チェック者は、これらを合格品と判断した。また、第２開孔部１８においても同様に、第２覆い部１６の厚さ以上の浮き上がり（段差）を第２覆い部１６に生じることはなかった。このような合格品では、第１開孔部１７および第２開孔部１８を介した通気量が設計値通りとなり、メーカーが予定した香喫味を喫煙者に提供できる。 On the other hand, in Examples 1 to 4, for example, as shown in FIG. 8, the second cover portion 16 has a lift (step) larger than the thickness of the second cover portion 16 around the first opening portion 17. There was no. In addition, illustration of the 2nd aperture part 18 is abbreviate | omitted in FIG. As described above, when the second cover portion 16 did not lift, the checker determined that these were acceptable products. Similarly, in the second opening portion 18, no lift (step) greater than the thickness of the second cover portion 16 was generated in the second cover portion 16. In such an acceptable product, the amount of ventilation through the first opening 17 and the second opening 18 is as designed, and the savory taste planned by the manufacturer can be provided to the smoker.
　第１実施形態および実施例１～４によれば、喫煙物品は、煙草部１２と、煙草部１２に隣接したフィルター本体２２と、フィルター本体２２の周囲を巻いた巻取物２３と、を有するフィルター部１３と、煙草部１２と、フィルター部１３の一部と、を覆う第１覆い部１５と、フィルター部１３の前記一部以外の部分を覆う第２覆い部１６と、フィルター部１３の軸Ｃ方向に互いに位置ずれした複数の開孔部（第１開孔部１７）であって、前記複数の開孔部のそれぞれが、第２覆い部１６を貫通する第１部分１７Ａと、巻取物２３を貫通する第２部分１７Ｂと、を有する複数の開孔部と、フィルター部１３の吸口側部分１３Ｂとフィルター部１３の煙草部側部分１３Ａとの間に設けられ、第２部分１７Ｂに対して第１部分１７Ａが位置ずれした第１位置Ｐ１と、第１部分１７Ａと第２部分１７Ｂとが整合した第２位置Ｐ２と、の間で、フィルター部１３の吸口側部分１３Ｂおよび第２覆い部１６をフィルター部１３の煙草部側部分１３Ａに対して回転可能な回転部２１と、を備える。 According to the first embodiment and Examples 1 to 4, the smoking article has the cigarette part 12, the filter body 22 adjacent to the cigarette part 12, and the wound material 23 wound around the filter body 22. A first cover 15 that covers the filter unit 13, the tobacco unit 12, and a part of the filter unit 13; a second cover unit 16 that covers a part other than the part of the filter unit 13; A plurality of apertures (first apertures 17) that are displaced from each other in the direction of the axis C, each of the apertures including a first portion 17A penetrating the second cover 16 and a winding A plurality of apertures having a second portion 17B penetrating through the catch 23, and a second portion 17B provided between a suction side portion 13B of the filter portion 13 and a tobacco portion side portion 13A of the filter portion 13; The first portion 17A is displaced relative to Between the first position P1 and the second position P2 where the first portion 17A and the second portion 17B are aligned, the suction side portion 13B and the second cover portion 16 of the filter portion 13 are connected to the tobacco portion of the filter portion 13. And a rotating portion 21 that is rotatable with respect to the side portion 13A.
　この構成によれば、複数の開孔部が軸Ｃ方向に互いに位置ずれしているため、複数の開孔部の周囲で第２覆い部１６に浮き上がりを生じることを防止できる。これによって、設計値の通りの通気量とすることができ、外部から必要以上に空気をフィルター部１３内に取り込んで、主流煙が薄くなり過ぎてしまうことを防止できる。 According to this configuration, since the plurality of opening portions are displaced from each other in the axis C direction, it is possible to prevent the second covering portion 16 from being lifted around the plurality of opening portions. As a result, the air flow rate can be set as designed, and it is possible to prevent the mainstream smoke from becoming excessively thin by taking air into the filter unit 13 more than necessary from the outside.
　また、複数の開孔部は、階段状に互いに位置ずれする。この構成によれば、第２覆い部１６の円周方向Ｒにも複数の開孔部同士を位置ずれさせることができ、複数の開孔部の周囲で第２覆い部１６に浮き上がりを生じることをより一層防止できる。 Also, the plurality of apertures are displaced from each other in a staircase pattern. According to this configuration, the plurality of opening portions can be displaced in the circumferential direction R of the second covering portion 16, and the second covering portion 16 is lifted around the plurality of opening portions. Can be further prevented.
　前記複数の開孔部のそれぞれの長辺は、第２覆い部１６の円周方向Ｒに延びる。この構成によれば、フィルター部１３の前記吸口側部分１３Ｂの回転角度を調整することで、複数の開孔部の第１部分１７Ａと、第２部分１７Ｂとの間のオーバーラップ量を容易に調整することができる。これによって、第２位置Ｐ２にあるときのように通気量を最大とした場合と、第１位置Ｐ１にあるときのように通気度を最低とした場合以外にも、それらの中間程度の通気度にすることができる。これによって、通気度が最大または最小の状態だけでなく、喫煙者の好みに沿うように適宜にそれらの中間程度の通気度に調整することが可能な喫煙物品を提供することができる。 Each long side of the plurality of apertures extends in the circumferential direction R of the second cover 16. According to this configuration, the amount of overlap between the first portion 17A and the second portion 17B of the plurality of apertures can be easily adjusted by adjusting the rotation angle of the inlet side portion 13B of the filter portion 13. Can be adjusted. As a result, in addition to the case where the air flow rate is maximized as in the second position P2 and the case where the air permeability is minimized as in the first position P1, the air permeability is about intermediate between them. Can be. Accordingly, it is possible to provide a smoking article that can be adjusted not only in a state where the air permeability is maximum or minimum, but also appropriately adjusted to an intermediate air permeability so as to conform to the smoker's preference.
　前記長辺は、０．５ｍｍ以上で、３ｍｍ以下である。この構成によれば、複数の開孔部の周囲で第２覆い部１６に浮き上がり等の不具合を生じることがなく、設計値の通りの通気度を持った喫煙物品を提供することができる。これによって、必要以上に煙が薄められることがなく、メーカーが予定した通りの香喫味を喫煙者が味わうことができる。 The long side is 0.5 mm or more and 3 mm or less. According to this configuration, it is possible to provide a smoking article having the air permeability as designed without causing problems such as lifting up to the second cover portion 16 around the plurality of opening portions. As a result, smoke is not diluted more than necessary, and the smoker can enjoy the savory taste as planned by the manufacturer.
　長辺は、１ｍｍ以上で、２ｍｍ以下である。この構成によれば、製造時の開孔部の大きさのばらつき等を考慮したとしても、より一層確実に複数の開孔部の周囲で第２覆い部１６に浮き上がり等の不具合を生じることを防止できる。 The long side is 1 mm or more and 2 mm or less. According to this configuration, even if the variation in the size of the apertures at the time of manufacture is taken into account, it is possible to more reliably cause problems such as lifting to the second cover portion 16 around the plurality of apertures. Can be prevented.
　また、喫煙物品は、前記複数の開孔部の位置からフィルター部１３の軸Ｃ周りに所定角度回転した位置に設けられるとともに、軸Ｃ方向に互いに位置ずれした複数の第２開孔部１８であって、複数の第２開孔部１８のそれぞれが、第２覆い部１６を貫通する第３部分１８Ａと、巻取物２３を貫通する第４部分１８Ｂと、を有する複数の第２開孔部１８を備え、回転部２１は、第４部分１８Ｂに対して第３部分１８Ａが位置ずれした第１位置Ｐ１と、第４部分１８Ｂと第３部分１８Ａとが整合した第２位置Ｐ２と、の間で、フィルター部１３の吸口側部分１３Ｂおよび第２覆い部１６をフィルター部１３の煙草部側部分１３Ａに対して回転可能である。 In addition, the smoking article is provided at a position rotated by a predetermined angle around the axis C of the filter unit 13 from the position of the plurality of apertures, and at the plurality of second apertures 18 that are displaced from each other in the direction of the axis C. Each of the plurality of second opening portions 18 includes a plurality of second openings having a third portion 18A penetrating the second cover portion 16 and a fourth portion 18B penetrating the wound article 23. The rotation portion 21 includes a first position P1 where the third portion 18A is displaced relative to the fourth portion 18B, a second position P2 where the fourth portion 18B and the third portion 18A are aligned, The suction side portion 13B and the second cover portion 16 of the filter portion 13 can be rotated relative to the tobacco portion side portion 13A of the filter portion 13.
　この構成によれば、フィルター部１３の軸Ｃ回りに所定角度回転した位置に、複数の開孔部と同様の機能を有する複数の第２開孔部１８を設けることができる。これによって、第２覆い部１６の円周方向Ｒに関して、複数の開孔部と複数の第２開孔部１８との間の距離を十分にとることができる。このため、複数の開孔部の周囲および複数の第２開孔部１８の周囲において、第２覆い部１６に浮き上がりを生じることを防止しつつ、開孔部の総数を増やすことができ、通気度を高くして低タールレンジに対応した高通気性の喫煙物品を提供することができる。なお、複数の開孔部（第２開孔部１８）を用いて通気度を高く設定することは、喫煙物品を低タール化する手段として主要なものである。 According to this configuration, a plurality of second apertures 18 having the same function as the plurality of apertures can be provided at a position rotated by a predetermined angle around the axis C of the filter unit 13. Thereby, with respect to the circumferential direction R of the second cover portion 16, a sufficient distance between the plurality of aperture portions and the plurality of second aperture portions 18 can be obtained. For this reason, it is possible to increase the total number of apertures while preventing the second cover 16 from being lifted around the plurality of apertures and around the plurality of second apertures 18. The highly breathable smoking article corresponding to the low tar range can be provided by increasing the degree. Note that setting the air permeability high by using a plurality of apertures (second aperture 18) is a major means for reducing the tar of smoking articles.
　また、複数の第２開孔部１８は、階段状に互いに位置ずれする。この構成によれば、複数の第２開孔部１８を複数の開孔部（第１開孔部１７）と同様の構成にすることができ、第２開孔部１８の周囲で第２覆い部１６に浮き上がりを生じることをより一層防止できる。 Further, the plurality of second apertures 18 are displaced from each other in a stepped manner. According to this configuration, the plurality of second opening portions 18 can be configured in the same manner as the plurality of opening portions (first opening portion 17), and the second covering is provided around the second opening portion 18. It is possible to further prevent the part 16 from being lifted.
　この場合、前記所定角度は、１８０°である。この構成によれば、第２覆い部１６の円周方向Ｒに関して、複数の開孔部から最も遠い位置に複数の第２開孔部１８を配置することができ、開孔部および第２開孔部１８の周囲で第２覆い部１６に浮き上がりを生じることを極力防止することができる。また、第１位置Ｐ１から第２位置Ｐ２に切り替える際に、喫煙者にあえて大きな角度分だけ吸口側部分１３Ｂを回すことを要するように設計できるため、回転動作によって香喫味が変化する楽しさを喫煙者が感じることができる。これによって、嗜好品として喫煙者に興味をそそる喫煙物品を提供することができる。 In this case, the predetermined angle is 180 °. According to this configuration, with respect to the circumferential direction R of the second cover portion 16, the plurality of second opening portions 18 can be disposed at positions farthest from the plurality of opening portions, and the opening portions and the second opening portions can be disposed. It is possible to prevent the second cover portion 16 from being lifted as much as possible around the hole portion 18. In addition, when switching from the first position P1 to the second position P2, it can be designed to require the smoker to turn the mouthpiece side portion 13B by a large angle, so that the savory taste can be changed by the rotating operation. Smokers can feel. This makes it possible to provide a smoking article that is intriguing to the smoker as a favorite item.

With reference to FIGS. 11-13, the cigarette 11 which is an example of the smoking article of 4th Embodiment is demonstrated. The cigarette 11 of the fourth embodiment is different from that of the first embodiment in that the plurality of second apertures 18 are not provided and only the plurality of first apertures 17 are provided. Other parts are common to the first embodiment. For this reason, parts different from the first embodiment will be mainly described, and illustrations or descriptions of parts common to the first embodiment will be omitted.
　複数の第１開孔部１７（開孔部）は、互いに軸Ｃ方向に位置ずれている。複数の第１開孔部１７は、第２覆い部１６の円周方向Ｒにおいても、互いに位置ずれして設けられている。このため、複数の第１開孔部１７は、互いに階段状に位置ずれしている。本実施形態において、複数の第１開孔部１７は、例えば６個で構成されているが、第１開孔部１７の数は６個に限定されるものではなく、２～５個でもよいし、７個以上であってもよい。 The plurality of first opening portions 17 (opening portions) are displaced from each other in the axis C direction. The plurality of first opening portions 17 are also provided so as to be displaced from each other in the circumferential direction R of the second cover portion 16. For this reason, the plurality of first opening portions 17 are displaced from each other in a stepped manner. In the present embodiment, the plurality of first opening portions 17 is configured by six pieces, for example, but the number of the first opening portions 17 is not limited to six and may be 2 to 5 pieces. 7 or more.
　複数の第１開孔部１７のそれぞれは、長辺が第２覆い部１６（フィルター部１３）の円周方向Ｒに延びる長方形に形成されている。より具体的には、図３に示すように、第１開孔部１７のそれぞれは、開孔長辺が０．５～３ｍｍで形成され、開孔短辺が０．０５～０．５ｍｍで形成される。第１開孔部１７同士の形状は同じである。複数の第１開孔部１７のそれぞれは、長辺が第２覆い部１６（フィルター部１３）の円周方向Ｒに延びる長円形に形成されていてもよい。 Each of the plurality of first opening portions 17 is formed in a rectangle whose long side extends in the circumferential direction R of the second covering portion 16 (filter portion 13). More specifically, as shown in FIG. 3, each of the first aperture portions 17 is formed with an aperture long side of 0.5 to 3 mm and an aperture short side of 0.05 to 0.5 mm. It is formed. The shapes of the first opening portions 17 are the same. Each of the plurality of first opening portions 17 may be formed in an oval shape whose long side extends in the circumferential direction R of the second cover portion 16 (filter portion 13).
　複数の第１開孔部１７のそれぞれは、第２覆い部１６を貫通する第１部分１７Ａと、フィルター部１３（煙草部側部分１３Ａ）の巻取物２３を貫通してフィルター本体２２に至る第２部分１７Ｂと、を有する。 Each of the plurality of first opening portions 17 passes through the first portion 17A penetrating the second cover portion 16 and the wound material 23 of the filter portion 13 (the tobacco portion side portion 13A) to reach the filter main body 22. A second portion 17B.
　本実施形態のシガレット１１の作用について説明する。図１２に示すように、シガレット１１を包装箱から取り出した状態では、第１開孔部１７の第１部分１７Ａは、例えば、第１開孔部１７の第２部分１７Ｂに対して第２覆い部１６の円周方向Ｒに位置ずれした第１位置Ｐ１に配置している。喫煙者は、このままの状態でも、煙草部１２の先端に点火をして吸口２４から吸引をすることで、濃度の濃い煙による濃厚な香喫味を楽しむことができる。 The operation of the cigarette 11 of this embodiment will be described. As shown in FIG. 12, in the state where the cigarette 11 is taken out from the packaging box, the first portion 17A of the first hole portion 17 is, for example, a second cover with respect to the second portion 17B of the first hole portion 17. The portion 16 is disposed at a first position P1 that is displaced in the circumferential direction R. Even in this state, the smoker can enjoy a rich savory taste due to dense smoke by igniting the tip of the cigarette part 12 and sucking it from the suction port 24.
　喫煙者は、フィルター部１３の煙草部側部分１３Ａに対して吸口側部分１３Ｂおよび第２覆い部１６を回転させることで、上記した第１位置Ｐ１から、第１開孔部１７の第１部分１７Ａが第１開孔部１７の第２部分１７Ｂに対して整合した第２位置Ｐ２に移動できる。本実施形態では、図１２に示すように、吸口２４側からみて、吸口側部分１３Ｂを反時計回り方向（図１２中の矢印の方向）に例えば約３３０°回転させることで、図１２に示す第１位置Ｐ１から図１３に示す第２位置Ｐ２に移動させることができる。この状態では、図１３に矢印で示すように、複数の第１開孔部１７を介してフィルター部１３内に積極的に空気を取り込むことができる。これによって、フィルター部１３内を流れる煙が薄められ、喫煙者は、濃度が比較的に低い煙によるあっさりとした香喫味（軽い吸い口の香喫味）を楽しむことができる。この場合、第１開孔部１７および第２開孔部１８から取り入れられた空気が主流煙中で占める割合は、例えば６０～８０％の高い水準となる。また、喫煙者は、第１位置Ｐ１から第２位置Ｐ２にするために、約３３０°という大きい角度分だけ吸口側部分１３Ｂを回転できる構造となるため、嗜好品として喫煙者の興味をそそる構造が実現される。 The smoker rotates the suction side portion 13B and the second cover portion 16 with respect to the cigarette portion side portion 13A of the filter portion 13, whereby the first portion of the first opening portion 17 from the first position P1 described above. 17A can move to the second position P2 aligned with the second portion 17B of the first opening 17. In the present embodiment, as shown in FIG. 12, the suction side portion 13B is rotated counterclockwise (in the direction of the arrow in FIG. 12), for example, by about 330 ° as viewed from the suction port 24 side, as shown in FIG. It can be moved from the first position P1 to the second position P2 shown in FIG. In this state, as indicated by arrows in FIG. 13, air can be actively taken into the filter portion 13 through the plurality of first aperture portions 17. As a result, the smoke flowing through the filter unit 13 is diluted, and the smoker can enjoy a light savory taste (light taste of the light mouthpiece) due to the smoke having a relatively low concentration. In this case, the ratio of the air taken in from the first aperture 17 and the second aperture 18 in the mainstream smoke is a high level of, for example, 60 to 80%. In addition, since the smoker has a structure capable of rotating the inlet side portion 13B by a large angle of about 330 ° in order to change from the first position P1 to the second position P2, a structure that intrigues the smoker as a favorite item. Is realized.
　一方で、喫煙者は、予め上記第２位置Ｐ２にした状態で煙草部１２の先端に点火をすることで、当初から軽快な香喫味を味わうこともできる。また、喫煙者は、このように軽い吸い口を楽しんでいる途中で、濃度の濃い煙を味わいたくなった場合には、フィルター部１３の煙草部側部分１３Ａに対して吸口側部分１３Ｂおよび第２覆い部１６を、吸口２４側からみて時計回り方向に例えば約３３０°回転させることで、第２位置Ｐ２から第１位置Ｐ１に戻すことができる。これによって、喫煙者は、濃厚な吸い口の煙を味わうこともできる。 On the other hand, the smoker can also enjoy a light savory taste from the beginning by igniting the tip of the tobacco part 12 in the state where the second position P2 is set in advance. In addition, when the smoker wants to taste the dense smoke while enjoying the light mouthpiece in this way, the smoker side portion 13B and the second side portion 13A of the filter portion 13 are compared with the cigarette portion side portion 13A. The second cover portion 16 can be returned from the second position P2 to the first position P1 by rotating, for example, about 330 ° in the clockwise direction when viewed from the inlet 24 side. Thereby, the smoker can also taste the smoke from the mouthpiece.
　さらに、喫煙者は、第２位置Ｐ２の状態から吸口側部分１３Ｂおよび第２覆い部１６を若干の角度分回転させることで、複数の第１開孔部１７の第２部分１７Ｂに対して、第１部分１７Ａが一部だけオーバーラップした状態にすることができる。これによって、第１位置Ｐ１にあるときと、第２位置Ｐ２にあるときと、の中間程度の通気度に調整することもできる。 Furthermore, the smoker rotates the suction side portion 13B and the second cover portion 16 by a slight angle from the state of the second position P2, thereby to the second portions 17B of the plurality of first opening portions 17 The first portion 17A can be partially overlapped. Thereby, it is possible to adjust the air permeability to an intermediate level between the first position P1 and the second position P2.
　第４実施形態のシガレット１１は、第１実施形態と同様の方法で製造することができる。第４実施形態に関しても、第１実施形態の実施例１～４、比較例１、２の条件で調査を行った。その結果、第４実施形態の実施例１～４、比較例１、２について、第１実施形態と略同様の結果を得ることができた。 The cigarette 11 of the fourth embodiment can be manufactured by the same method as that of the first embodiment. Regarding the fourth embodiment, the investigation was performed under the conditions of Examples 1 to 4 and Comparative Examples 1 and 2 of the first embodiment. As a result, substantially the same results as in the first embodiment were obtained for Examples 1 to 4 of the fourth embodiment and Comparative Examples 1 and 2.
　第４実施形態および第４実施形態の実施例１～４の喫煙物品によって得られる効果は、第１実施形態と略同様である。さらに、本実施形態によれば、複数の第２開孔部１８が設けられないため、第１位置Ｐ１から第２位置Ｐ２にする際の吸口側部分１３Ｂおよび第２覆い部１６の回転角度を大きくとることができる。これによって、第１位置Ｐ１から第２位置Ｐ２に切り替える際に、喫煙者にあえて大きな角度分だけ吸口側部分１３Ｂを回すことを要するように設計できるため、回転動作によって香喫味が変化する楽しさを喫煙者が感じることができる。これによって、嗜好品として喫煙者に興味をそそるシガレット１１を提供することができる。 The effects obtained by the smoking articles of the fourth embodiment and Examples 1 to 4 of the fourth embodiment are substantially the same as those of the first embodiment. Further, according to the present embodiment, since the plurality of second opening portions 18 are not provided, the rotation angle of the suction side portion 13B and the second cover portion 16 when changing from the first position P1 to the second position P2 is set. It can be taken big. Thus, when switching from the first position P1 to the second position P2, it can be designed to require the smoker to turn the mouthpiece side portion 13B by a large angle, so that the savory taste is changed by the rotation operation. The smoker can feel. Thereby, the cigarette 11 intriguing the smoker can be provided as a luxury item.
　喫煙物品（シガレット１１）は上記実施形態に限定されるものではなく、実施段階ではその要旨を逸脱しない範囲で構成要素を変形して具体化できる。また、上記した異なる実施形態中の構成要素を適宜に組み合わせて一つのシガレット１１を実現することもできる。 The smoking article (cigarette 11) is not limited to the above embodiment, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Moreover, the single cigarette 11 can also be realized by appropriately combining the components in the different embodiments described above.
