Description
本発明は、フィルタシガレットが喫煙される直前に、フィルタシガレットの吸口端に取り付けられる補助フィルタに関する。 The present invention relates to an auxiliary filter attached to a suction end of a filter cigarette immediately before the filter cigarette is smoked.
この種の補助フィルタは、両端が開口した中空且つ円筒状の外被、即ち、シースと、このシースの一端部内に収容された少なくとも１個のフィルタ要素と、シース内にてシースの他端とフィルタ要素との間に確保され、棒状喫煙物品の吸口端を受け入れ可能な凹所とを含む（例えば、特許文献１，２）。
前記特許文献１，２の補助フィルタの他端、即ち、凹所の開口面は何れも、補助フィルタの軸線と直交している。それ故、棒状喫煙物品の吸口端への補助フィルタの取り付け、即ち、シースの凹所内への棒状喫煙物品の吸口端の挿入が容易ではなく、また、この補助フィルタの取り付け後、棒状喫煙物品からの補助フィルタの不所望な脱落が防止されるためには、凹所の内径に高い寸法精度が要求される。 The other ends of the auxiliary filters of Patent Documents 1 and 2, that is, the opening surfaces of the recesses are all orthogonal to the axis of the auxiliary filter. Therefore, it is not easy to attach the auxiliary filter to the mouth end of the rod-shaped smoking article, i.e., to insert the mouth end of the rod-shaped smoking article into the recess of the sheath. In order to prevent undesired dropping of the auxiliary filter, high dimensional accuracy is required for the inner diameter of the recess.
このような事情から、特許文献１，２のシースは何れも合成樹脂の射出成形することによって形成されており、このような射出成形は、高い寸法精度の凹所を備えた補助フィルタの提供を可能にする。しかしながら、この種の補助フィルタは使い捨てであるため、補助フィルタ、即ち、シースの廃棄は環境負荷を増加させる大きな要因となる。 Under these circumstances, the sheaths of Patent Documents 1 and 2 are both formed by injection molding of synthetic resin, and such injection molding provides an auxiliary filter having a recess with high dimensional accuracy. enable. However, since this type of auxiliary filter is disposable, discarding the auxiliary filter, that is, the sheath, is a major factor that increases the environmental load.
更に、棒状喫煙物品に補助フィルタが取り付けられた後、この補助フィルタの一端部は棒状喫煙物品自体の吸口端に代えて、棒状喫煙物品のための新たな吸口端となる。しかしながら、上述したように補助フィルタのシースが合成樹脂から形成されている場合、喫煙者は補助フィルタの吸口端を銜えたとき、補助フィルタに違和感を覚えることもある。 Further, after the auxiliary filter is attached to the rod-like smoking article, one end of the auxiliary filter becomes a new mouth end for the rod-like smoking article instead of the mouth end of the rod-like smoking article itself. However, when the sheath of the auxiliary filter is made of synthetic resin as described above, the smoker may feel uncomfortable with the auxiliary filter when holding the suction end of the auxiliary filter.
本発明の目的は、環境負荷を増大させず、且つ、喫煙時、喫煙者に違和感を与えることのないフィルタシガレットのための補助フィルタを提供することにある。 An object of the present invention is to provide an auxiliary filter for a filter cigarette that does not increase the environmental load and does not give the smoker a feeling of strangeness when smoking.
上記の目的を達成するため、本発明は、吸口端にフィルタを有する一方、その吸口端にフィルタ内への空気の導入を許容する穿孔列を有したフィルタシガレットのための補助フィルタであって、可撓性を有する紙材料から形成され、両端が開口した中空円筒状の紙シースと、この紙シース内に紙シースの一端部に位置して収容された円筒状のフィルタ要素と、紙シースの他端部内に確保され、フィルタシガレットの吸口端が挿入される凹所と、紙シースの他端開口に設けられ、紙シースの軸線に対して非直交状態にある傾斜開口域と
を備え、
紙シースの凹所にフィルタシガレットの吸口端が挿入されたとき、紙シースの一端部はフィルタ要素とともに新たな吸口端を提供し、傾斜開口域はフィルタシガレットの挿入量に応じてフィルタシガレットの穿孔列を部分的に露出させる（請求項１）。
In order to achieve the above object, the present invention is an auxiliary filter for a filter cigarette having a filter at the suction end, and having a perforation row at the suction end that allows introduction of air into the filter. A hollow cylindrical paper sheath formed of a flexible paper material and open at both ends, a cylindrical filter element housed in one end of the paper sheath in the paper sheath, and a paper sheath is secured in the other end, a recess mouth end of the filter cigarette is inserted, provided on the other end opening of the paper sheath, and an inclined opening area in a non-orthogonal state relative to the axis of the paper sheath
With
When the suction end of the filter cigarette is inserted into the recess of the paper sheath, one end of the paper sheath provides a new suction end together with the filter element, and the inclined opening area perforates the filter cigarette according to the insertion amount of the filter cigarette The column is partially exposed (claim 1).
本発明の補助フィルタ、即ち、紙シースの他端は上述の傾斜開口域を有するので、紙シースの軸線の軸線に対して全体が直交する他端に比べて広い開口面積を有する。即ち、紙シースの軸線に対して直交しない傾斜開口域は、補助フィルタにおける他端の開口面積を増加させる。また、紙シースの外周はその他端部での変形が許容されている。 Since the other end of the auxiliary filter of the present invention, that is, the paper sheath has the above-described inclined opening region, it has a wider opening area than the other end that is entirely orthogonal to the axis of the axis of the paper sheath. That is, the inclined opening area that is not orthogonal to the axis of the paper sheath increases the opening area of the other end of the auxiliary filter. Further, the outer periphery of the paper sheath is allowed to be deformed at the other end.
それ故、例え、紙シースの内径がフィルタシガレットの吸口端部の外径に実質的に等しくても、フィルタシガレットの吸口端部は、紙シースの他端を通じて凹所内に容易に差込み可能となる。即ち、フィルタシガレットに対する補助フィルタの取り付けは容易である。しかも、補助フィルタの取り付け後、紙シースの他端部はフィルタシガレットの吸口端部に密着し、フィルタシガレットから補助フィルタが不所望に脱落することもない。 Thus, for example, be substantially equal the inner diameter of the paper sheath to the outer diameter of the mouth end of the filter cigarette, mouthpiece end of the filter cigarette, easily allows insertion into the recess through the other end of the paper sheath . That is, it is easy to attach the auxiliary filter to the filter cigarette . Moreover, after mounting of the auxiliary filter, the other end portion of the paper sheath in close contact with the mouth end of the filter cigarette, the auxiliary filter from the filter cigarettes nor fall off undesirably.
具体的には、紙シースの他端は傾斜開口端として形成され、この傾斜開口端はその全体が前記紙シースの軸線に対して傾斜した傾斜開口域を提供する（請求項２）。また、紙シースの他端は、傾斜開口端に代えて、半傾斜開口端（請求項３）、又は、嘴開口端（請求項４）として形成されていてもよい。 Specifically, the other end of the paper sheath is formed as an inclined opening end, and this inclined opening end provides an inclined opening region whose whole is inclined with respect to the axis of the paper sheath (claim 2) . The other end of the paper sheath may be formed as a semi- inclined open end (Claim 3) or a heel open end (Claim 4) instead of the inclined open end.
半傾斜開口端は、組シースの軸線に直交した径方向開口域と、この径方向開口域から紙シースの一端側に向けて後退するように延びる傾斜開口域とを有し、これに対し、嘴開口端は、径方向開口域と、この径方向開口域から紙シースの他端側に向けて飛び出す傾斜した傾斜開口域とを有する。 Half inclined open end has a radially opening area orthogonal to the axis of the assembled sheath, and an inclined opening area extending as to retract toward this radial opening area on one end side of the paper sheath, contrast, beak open end has a radially opening area, and an inclined opening region inclined jumping out toward this radial opening area on the other side of the paper sheath.
上述の半傾斜開口端及び嘴開口端の何れにあっても、紙シースの軸線に対して非直交状態の傾斜開口域をそれぞれ有することから、これら傾斜開口域もまた前述した利点を発揮する。 In any of the semi-inclined open end and beak open end of the above, the inclined open mouth zone of non-orthogonal state relative to the axis of the paper sheath since the chromatic respectively, also exhibit the advantages described above the inclined opening area To do.
前述したように本発明のフィルタシガレットのための補助フィルタ（請求項１〜４）は、紙シースの他端にその開口面積を増加させるべく、紙シースの軸線とは非直交状態にある傾斜開口域を有する。それ故、紙シースの内径とフィルタシガレットにおける吸口端部の外径とが実質的に同一であっても、フィルタしガレットに対する補助フィルタの取り付けが容易になり、しかも、この取り付け後、補助フィルタの紙シースはフィルタシガレットに良好に密着し、フィルタシガレットからの補助フィルタの不所望な脱落は確実に防止される。 As described above, the auxiliary filter for the filter cigarette of the present invention (Claims 1 to 4) is an inclined opening that is non-orthogonal with the axis of the paper sheath so as to increase the opening area of the other end of the paper sheath. Has a zone. Therefore, even if the inner diameter of the paper sheath and the outer diameter of the suction end of the filter cigarette are substantially the same, the attachment of the auxiliary filter to the filter gallet is facilitated. paper sheath satisfactorily close contact with the filter cigarettes, undesired falling off of the auxiliary filter from the filter cigarettes are reliably prevented.
また、フィルタシガレットの喫煙時、補助フィルタの紙シースが喫煙者により銜えられても、喫煙者に違和感を与えることはなく、補助フィルタはフィルタシガレット自体の吸口端を銜えた場合と同様な感覚を喫煙者に提供することができる。
更に、補助フィルタの傾斜開口域から露出する穿孔列の割合を補助フィルタへのフィルタシガレットの挿入量により調整可能となる。
Also, when smoking a filter cigarette , even if the smoker holds the paper sheath of the auxiliary filter, the smoker does not feel uncomfortable, and the auxiliary filter feels the same as if the mouth of the filter cigarette itself was held. Can be provided to smokers.
Furthermore, the ratio of the perforated row exposed from the inclined opening area of the auxiliary filter can be adjusted by the amount of filter cigarette inserted into the auxiliary filter.
図１は、第１実施例の補助フィルタ２を示し、この補助フィルタ２はフィルタシガレットＦＣの吸口端に取り付け可能である。先ず、フィルタシガレットＦＣについて説明すると、フィルタシガレットＦＣは、シガレットＣと、このシガレットＣの一端に隣接して配置されたフィルタチップＦと、このフィルタチップＦをシガレットＣに接続するチップペーパＴＰとを含み、このチップペーパＴＰはシガレットＣの一端からフィルタチップＦの全体に亘って、これらの外周面に巻き付けられている。更に、この実施例の場合、フィルタチップＦは、チャコールフィルタ要素ＦC及びプレーンフィルタ要素ＦAとを有し、これらフィルタ要素はタンデムに配置されている。即ち、フィルタチップＦはデュアルフィルタチップである。 Figure 1 shows an auxiliary filter 2 of the first embodiment, the auxiliary filter 2 is attachable to the mouth end of the full I filter cigarettes FC. First, the filter cigarette FC will be described. The filter cigarette FC includes a cigarette C, a filter chip F disposed adjacent to one end of the cigarette C, and a chip paper TP that connects the filter chip F to the cigarette C. This chip paper TP is wound around these outer peripheral surfaces from one end of the cigarette C to the entire filter chip F. Further, in this embodiment, the filter chip F has a charcoal filter element F C and a plane filter element F A, and these filter elements are arranged in tandem. That is, the filter chip F is a dual filter chip.
補助フィルタ２は中空円筒形状の紙シース４を備え、この紙シース４はそれぞれ開口した両端を有する。好ましくは、紙シース４は、前述したチップペーパＴＰと同様な可撓性を有する紙材料から形成されている。紙シース４の内径ＤiはフィルタシガレットＦＣにおける吸口端の外径Ｄoと実質的に等しいか、又は、この外径Ｄoよりも若干小さい。 The auxiliary filter 2 includes a hollow cylindrical paper sheath 4, which has both open ends. Preferably, the paper sheath 4 is formed of a paper material having flexibility similar to the above-described tip paper TP. The inner diameter Di of the paper sheath 4 is substantially equal to or slightly smaller than the outer diameter Do of the suction end of the filter cigarette FC.
紙シース４内にはメンソールフィルタ要素６が収容されており、このメンソールフィルタ要素６は紙シース４の一端部内に位置付けられている。例えば、メンソールフィルタ要素６はアセテート繊維の束からなる円筒状のフィルタ材と、このフィルタ材中に一様に分布されたメンソールの粒子と、フィルタ材の外周面を囲む包材とを有する。 A menthol filter element 6 is accommodated in the paper sheath 4, and the menthol filter element 6 is positioned in one end of the paper sheath 4. For example, the menthol filter element 6 includes a cylindrical filter material made of a bundle of acetate fibers, menthol particles uniformly distributed in the filter material, and a wrapping material surrounding the outer peripheral surface of the filter material.
なお、前述したチャコールフィルタ要素ＦＣはメンソールの粒子に代えて活性炭の粒子を有し、そして、前述したプレーンフィルタＦＡは何ら粒子を含んでいない。Incidentally, charcoal filter element F C described above has a particle of the activated carbon in place of the particles of menthol and plain filter F A described above does not contain any particles.
第１実施例の場合、紙シース４の他端は傾斜開口端８として形成されており、この傾斜開口端８はその全体が紙シース４の軸線に対して傾斜した開口域を有する。即ち、傾斜開口端８を含む仮想の面を考えたとき、この面は紙シース４の軸線に対して非直交状態にある。 In the case of the first embodiment, the other end of the paper sheath 4 is formed as an inclined opening end 8, and the inclined opening end 8 has an opening area that is entirely inclined with respect to the axis of the paper sheath 4. That is, when a virtual surface including the inclined opening end 8 is considered, this surface is in a non-orthogonal state with respect to the axis of the paper sheath 4.
紙シース４内へのメンソールフィルタ要素６の収容は、紙シース２の他端部内に凹所９を規定する。この凹所９のサイズ、即ち、図１でみて傾斜開口端８の尖端８ａとメンソールフィルタ要素６との間の距離Ｌ１は、前述したプレーンフィルタ要素ＦＡの長さよりも長い方が好ましい。より具体的には、フィルタシガレットＦＣの喫煙時、チャコールフィルタ要素ＦＣ内への外気の導入を許容するためにチップペーパＴＰに穿孔列Ｈ（図２参照）が備えられている場合、穿孔列ＨからフィルタシガレットＦＣの吸口面までの距離をＬ２とすれば、距離Ｌ１，Ｌ２は以下の関係にある。
Ｌ１＞Ｌ２＋αThe accommodation of the menthol filter element 6 in the paper sheath 4 defines a recess 9 in the other end of the paper sheath 2. The size of the recess 9, i.e., the distance L 1 between the tip 8a and menthol filter element 6 of the inclined open end 8 as viewed in FIG. 1, it is preferable longer than the length of the plain filter element F A described above. More specifically, when smoking filter cigarettes FC, if the paper web TP perforation row H (see FIG. 2) is provided to allow the introduction of outside air into the charcoal filter within element F C, drilling string if the distance from H to mouthpiece face of the filter cigarette FC and L 2, the distance L 1, L 2 are in the following relationship.
L 1 > L 2 + α
フィルタシガレットＦＣへの第１実施例の補助フィルタ２の取り付けに際し、例えば、図２に示されるように補助フィルタ２はその傾斜開口端８が上方に向けて開口した姿勢に保持される。このような状態にて、補助フィルタ２の傾斜開口端８に対して、フィルタシガレットＦＣはその吸口端ＥＭを斜め上方から挿入すべ移動され、これにより、吸口端ＥＭが傾斜開口端８から凹所９内に侵入する。When the auxiliary filter 2 of the first embodiment is attached to the filter cigarette FC, for example, as shown in FIG. 2, the auxiliary filter 2 is held in a posture in which the inclined opening end 8 is opened upward. At this state, the inclined open end 8 of the auxiliary filter 2, the filter cigarettes FC is inserted all move the mouth end E M obliquely from above, thereby, the mouth end E M is an inclined open end 8 It penetrates into the recess 9.
ここで、紙シース４の内径が吸口端ＥＭの外径と実質的に同一であっても、図３から明らかなように傾斜開口端８の開口面積は吸口端ＥＭの面積よりも大きく、しかも、傾斜開口端８の環状縁は図３中の２点鎖線で示すように外側に向けて変形可能である。それ故、吸口端ＥＭは傾斜開口端８から凹所９内、即ち、補助フィルタ２内に簡単且つ円滑に挿入される。Here, also the inner diameter of the paper sheath 4 is an outer diameter substantially the same mouth end E M, the opening area of the apparent slanted opening end 8 of FIG. 3 is greater than the area of the mouth end E M Moreover, the annular edge of the inclined opening end 8 can be deformed outward as indicated by a two-dot chain line in FIG. Therefore, the suction end E M is easily and smoothly inserted from the inclined opening end 8 into the recess 9, that is, into the auxiliary filter 2.
この結果、図４に示されるようにフィルタシガレットＦＣの吸口端ＥＭが補助フィルタ２の凹所９内に部分的に挿入された状態で、吸口端ＥＭに補助フィルタ２が取り付けられる。そして、補助フィルタ２が一旦取り付けられた後、紙シース４の内周面は吸口端ＥＭの外周面に密着し、吸口端ＥＭからの補助フィルタ２の脱落が確実に防止される。As a result, in a state where the mouth end E M filter cigarettes FC is partially inserted into the recess 9 of the auxiliary filter 2 as shown in FIG. 4, the auxiliary filter 2 is attached to the mouthend E M. After the auxiliary filter 2 is attached once, the inner peripheral surface of the paper sheath 4 is in close contact with the outer peripheral surface of the mouth end E M, dropping the auxiliary filter 2 from the mouth end E M is reliably prevented.
また、図４から明らかなようにフィルタシガレットＦＣに補助フィルタ２が取り付けられたとき、フィルタシガレットＦＣにおけるチップペーパＴＰの穿孔列Ｈはその一部が補助フィルタ２の傾斜開口端８から露出し、その残部は補助フィルタ２の紙シース４により閉塞される。 4, when the auxiliary filter 2 is attached to the filter cigarette FC, a part of the perforated row H of the chip paper TP in the filter cigarette FC is exposed from the inclined opening end 8 of the auxiliary filter 2, The remaining portion is closed by the paper sheath 4 of the auxiliary filter 2.
第１実施例の補助フィルタ２はその内部にメンソールフィルタ要素６を収容しているので、補助フィルタ２が取り付けられたフィルタシガレットＦＣが喫煙されたとき、フィルタシガレットＦＣの主流煙中にはメンソールフィルタ要素６から発生したメンソールの香りが付加される。この結果、喫煙者は、シガレットＣ本来の風味や味覚に加え、メンソールの香りをも味わうことができる。 Since the auxiliary filter 2 of the first embodiment houses the menthol filter element 6 therein, when the filter cigarette FC to which the auxiliary filter 2 is attached is smoked, the mainstream smoke of the filter cigarette FC includes the menthol filter. The menthol scent generated from element 6 is added. As a result, the smoker can taste the scent of menthol in addition to the original flavor and taste of cigarette C.
紙シース４は紙から形成されているので、補助フィルタ２の使用後、補助フィルタ２がフィルタシガレットＦＣの吸い殻とともに廃棄されても、補助フィルタ２の廃棄が環境負荷の増大させることはなく、また、喫煙者が補助フィルタ２の一端部、即ち、その吸口端を銜えても、補助フィルタ２に違和感を覚えることはない。 Since the paper sheath 4 is formed of paper, even if the auxiliary filter 2 is discarded together with the cigarette FC butts after use of the auxiliary filter 2, the disposal of the auxiliary filter 2 does not increase the environmental load. Even if the smoker holds one end of the auxiliary filter 2, that is, the suction end, the auxiliary filter 2 does not feel uncomfortable.
更に、補助フィルタ２はフィルタシガレットＦＣの１本毎に使用されるので、補助フィルタ２の使い回しが防止され、補助フィルタ２は衛生面でも優れる。 Furthermore, since the auxiliary filter 2 is used for each filter cigarette FC, the auxiliary filter 2 is prevented from being reused, and the auxiliary filter 2 is excellent in terms of hygiene.
前述したように穿孔列Ｈは補助フィルタ２の紙シース４により部分的に閉塞されることから、喫煙時、フィルタシガレットＦＣのフィルタチップＦ内に流入する空気量、即ち、フィルタチップＦの通気度Ｖｆは、補助フィルタ２の取り付け前と取り付け後との間にて変化する。しかしながら、穿孔列Ｈが紙シース４によって閉塞される割合、即ち、通気度Ｖｆは傾斜開口端８の傾斜角や補助フィルタ２内への吸口端ＥＭの挿入量等により制御可能である。それ故、通気度Ｖｆが適切に制御されれば、補助フィルタ２の取り付けの前後にて、フィルタシガレットＦＣのＴＮ値（Ｔ：タール，Ｎ：ニコチン）を変化させることなく、フィルタシガレットＦＣの主流煙にメンソールの香りを付加可能となる。Since the perforated row H is partially blocked by the paper sheath 4 of the auxiliary filter 2 as described above, the amount of air flowing into the filter chip F of the filter cigarette FC during smoking, that is, the air permeability of the filter chip F. Vf changes between before and after the auxiliary filter 2 is attached. However, the percentage of perforations column H is closed by the paper sheath 4, i.e., the air permeability Vf can be controlled by the insertion amount of the mouth end E M to the inclination angle and auxiliary filter 2 of the inclined open end 8. Therefore, if the air permeability Vf is appropriately controlled, the mainstream of the filter cigarette FC without changing the TN value (T: tar, N: nicotine) of the filter cigarette FC before and after the auxiliary filter 2 is attached. A menthol scent can be added to the smoke.
図５は、参考例の補助フィルタ２を示す。
参考例の補助フィルタ２は、前述した傾斜開口端８に代えて段付き開口端１０を有する。この段付き開口端１０は、２つの径方向開口域１０ａ，１０ｂと、１つの軸方向開口域１０ｃを有する。径方向開口域１０ａ，１０ｂは補助フィルタ２の軸線方向に互いにずれた状態にある。即ち、図２から明らかなように開口域１０ｂは開口域１０ａよりも紙シース４の一端側に位置付けられており、紙シース４の他端側からみて、径方向開口域１０ａ，１０ｂは半円形状をなし、共に紙シース４の一端とは反対側に向けて開いている。これに対し、軸方向開口域１０ｃは、開口域１０ａ，１０ｂ間に亘って紙シース４の軸線方向に延び、補助フィルタ２の径方向外側に向けて開いている。即ち、径方向開口域１０ａ，１０ｂは補助フィルタ２の軸線に対して直交しているのに対し、軸方向開口域１０ｂは補助フィルタ２の軸線と平行である。
FIG. 5 shows an auxiliary filter 2 of a reference example .
The auxiliary filter 2 of the reference example has a stepped opening end 10 instead of the inclined opening end 8 described above. The stepped opening end 10 has two radial opening areas 10a and 10b and one axial opening area 10c. The radial opening areas 10 a and 10 b are in a state of being shifted from each other in the axial direction of the auxiliary filter 2. That is, as is apparent from FIG. 2, the opening area 10b is positioned closer to one end side of the paper sheath 4 than the opening area 10a, and the radial opening areas 10a and 10b are semicircular when viewed from the other end side of the paper sheath 4. Both have a shape and are open toward the opposite side of one end of the paper sheath 4. On the other hand, the axial opening area 10 c extends in the axial direction of the paper sheath 4 between the opening areas 10 a and 10 b and opens toward the radial outer side of the auxiliary filter 2. That is, the radial opening areas 10 a and 10 b are orthogonal to the axis of the auxiliary filter 2, whereas the axial opening area 10 b is parallel to the axis of the auxiliary filter 2.

FIG. 6 shows the auxiliary filter 2 of the second embodiment.
The auxiliary filter 2 of the second embodiment has a semi-inclined opening end 12 in place of the inclined opening end 8 or the stepped opening end 10 described above. The semi-inclined opening end 12 has a radial opening area 12a and an inclined opening area 12b. The radial opening area 12a corresponds to the above-described radial opening area 10a, while the inclined opening area 12b is inclined with respect to the radial opening area 12a so as to recede toward one end side of the paper sheath 4, It extends between the opening area 12 a and the outer peripheral edge of the paper sheath 4.
図７は、第３実施例の補助フィルタ２を示す。
第３実施例の補助フィルタ２は、前述の開口端８又は１２に代えて、嘴開口端１４を有する。この嘴開口端１４は傾斜開口域１４ａと、径方向開口域１４ｂとを有する。径方向開口域１４ｂは前述した径方向開口域１０ｂに相当し、これに対し、傾斜開口域１４ａは径方向開口域１４ｂに対し、紙シース４の他端側に向けて飛び出すように傾斜し、開口域１４ｂと紙シース４の外周縁との間に亘って延びている。
FIG. 7 shows the auxiliary filter 2 of the third embodiment.
The auxiliary filter 2 of the third embodiment has a heel opening end 14 instead of the opening end 8 or 12 described above. The eaves opening end 14 has an inclined opening area 14a and a radial opening area 14b. The radial opening area 14b corresponds to the above-described radial opening area 10b, whereas the inclined opening area 14a is inclined with respect to the radial opening area 14b so as to protrude toward the other end side of the paper sheath 4, It extends between the opening area 14 b and the outer peripheral edge of the paper sheath 4.
上述した半傾斜開口端１２及び嘴開口端１４もまた、第１実施例の傾斜開口端８と同様な機能を発揮する。 The semi- inclined opening end 12 and the heel opening end 14 described above also exhibit the same function as the inclined opening end 8 of the first embodiment.
また、補助フィルタ２はその紙シース４内にメンソールフィルタ要素６に代えて、他の香料を含むフィルタ要素、チャコールタイプ又はプレーンタイプのフィルタ要素を収容可能である。更に、フィルタ要素は、このフィルタ要素と紙シース４の一端との間に凹所を残して、紙シース４内に位置付けられていてもよい。 The auxiliary filter 2 can accommodate a filter element containing other fragrance, a charcoal type or a plain type filter element in the paper sheath 4 instead of the menthol filter element 6. Further, the filter element may be positioned in the paper sheath 4 leaving a recess between the filter element and one end of the paper sheath 4.
