Description

シガレット用フィルターおよびシガレットCigarette filters and cigarettes
　本発明は、香料カプセルを含むシガレット用フィルターおよびシガレットに関する。 The present invention relates to a cigarette filter and a cigarette containing a fragrance capsule.
　従来から、シガレット用フィルターに香料カプセルを組み込み、使用時に香料カプセルを破砕し、喫煙時に内容液の香りを楽しんだり、消火後の吸殻のにおいをマスキングすることが行われている（特許文献１～５）。香料カプセルの詳細については、たとえば特許文献６に記載されている。このような香料カプセルを含むシガレット用フィルターには様々な問題がある。 Conventionally, a fragrance capsule is incorporated into a cigarette filter, the fragrance capsule is crushed during use, and the scent of the contents liquid is enjoyed during smoking, or the smell of the butts after extinguishing is masked (Patent Documents 1 to 5). 5). The details of the fragrance capsule are described in Patent Document 6, for example. There are various problems with cigarette filters containing such a fragrance capsule.
　図１（ａ）は、たばこ充填物１１を巻紙１２で巻いたたばこロッド１０と、香料カプセル２１を埋め込んだフィルタープラグ２２を巻取紙２３で巻いたフィルター２０とをチップペーパー３０で接続したシガレットを示している。香料カプセル２１は皮膜２１ａで内容液２１ｂを包み込んだ構造を有する。このようなシガレットを喫煙する際に、香料カプセル２１の皮膜２１ａをつぶすと、図１（ｂ）に示すように流れ出た内容液２１ｂはフィルタープラグ２２に吸収され、チップペーパー３０の表面に染み出ることはない。しかし、フィルタープラグ２２に埋め込まれた香料カプセル２１はつぶした感触がないので使用感に劣る。 FIG. 1A shows a cigarette in which a cigarette rod 10 in which a cigarette filling 11 is wound with a wrapping paper 12 and a filter 20 in which a filter plug 22 in which a fragrance capsule 21 is embedded is wound with a winding paper 23 are connected by a chip paper 30. ing. The fragrance capsule 21 has a structure in which the content liquid 21b is wrapped with a film 21a. When smoking such a cigarette, if the film 21a of the fragrance capsule 21 is crushed, the content liquid 21b flowing out as shown in FIG. 1B is absorbed by the filter plug 22 and oozes out to the surface of the chip paper 30. There is nothing. However, since the fragrance capsule 21 embedded in the filter plug 22 does not have a crushed feeling, it is inferior in use feeling.
　そこで、複数のフィルタープラグを互いに離間し中空部を介して配置し、その中空部に香料カプセルを設けた構造のフィルターであれば、香料カプセルをつぶした感触が得られるので使用感に優れている。 Therefore, a filter having a structure in which a plurality of filter plugs are spaced apart from each other and arranged through a hollow portion and a fragrance capsule is provided in the hollow portion is excellent in usability because a squeezed fragrance capsule can be obtained. .
　図２（ａ）は、たばこ充填物１１を巻紙１２で巻いたたばこロッド１０と、２つのフィルタープラグ２５の間の中空部に香料カプセル２１を設けた構造のフィルター２０とをチップペーパー３０で接続したシガレットを示している。２つのフィルタープラグ２５の周囲には素材紙２６が巻かれ、両者が互いに離間し中空部を介して配置された周囲に成形紙２７が巻かれている。なお、素材紙と成形紙のいずれか一方または両方を有さないフィルタープラグも存在する（図１の場合は素材紙と成形紙を兼ねた巻取紙のみである）。通常の成形紙は透過性の高い素材で作られているため、このようなシガレットを喫煙する際に、香料カプセル２１の皮膜２１ａをつぶすと、図２（ｂ）に示すように流れ出た内容液２１ｂがチップペーパー３０の表面に染み出す。 In FIG. 2A, the tobacco rod 10 in which the tobacco filler 11 is wound with the wrapping paper 12 and the filter 20 having the structure in which the fragrance capsule 21 is provided in the hollow portion between the two filter plugs 25 are connected by the chip paper 30. Shows the cigarettes. A material paper 26 is wound around the two filter plugs 25, and a forming paper 27 is wound around a space where both are separated from each other and disposed through a hollow portion. There is also a filter plug that does not have either one or both of the raw paper and the molded paper (in the case of FIG. 1, only the rolled paper that serves as the raw paper and the molded paper is used). Since ordinary paper is made of a highly permeable material, when the cigarette 21 is smoked, when the film 21a of the fragrance capsule 21 is crushed, the content liquid that flows out as shown in FIG. 21b oozes out to the surface of the chip paper 30.
　チップペーパーの表面への内容液の染み出しを抑制するために、液体不透過性のチップペーパーおよび／またはフィルターラッパー（素材紙、成形紙、巻取紙）を用いることが考えられる。これらの素材は紙に限定されず、セロファンやプラスチック製のラップ、またはそれらの複合素材でもよい。成形紙２７を液体不透過性とした場合、図２（ｃ）に示すように流れ出た内容液２１ｂが液体不透過性の成形紙２７の内側とフィルタープラグ２５のすき間に沿ってたばこロッド１０や吸口端の方向へ移動する。そして、ついにはたばこロッド１０のたばこ充填物１１を経て、チップペーパー３０よりたばこロッド１０側の巻紙１２へ染み出しが発生する。吸口端の方向では、成形紙２７の内側とフィルタープラグ２５のすき間に沿ってフィルタープラグ２５の端面に染み出しが発生する。 It is conceivable to use liquid-impermeable chip paper and / or filter wrappers (material paper, molded paper, web) in order to suppress the exudation of the content liquid on the surface of the chip paper. These materials are not limited to paper, but may be cellophane, plastic wrap, or a composite material thereof. When the molding paper 27 is liquid-impermeable, as shown in FIG. 2C, the content liquid 21 b that has flowed out is disposed along the gap between the liquid-impermeable molding paper 27 and the gap between the filter plug 25 and the tobacco rod 10. Move in the direction of the inlet end. Finally, the tobacco rod 10 is filled with the tobacco filler 11 and ooze out from the tip paper 30 to the wrapping paper 12 on the tobacco rod 10 side. In the direction of the suction end, seepage occurs on the end face of the filter plug 25 along the gap between the inner side of the forming paper 27 and the filter plug 25.
　この問題は、液体不透過性の成形紙２７の内側にワックスや糊を塗り、成形紙２７の内側とフィルタープラグ２５のすき間を塞ぐことによって、内溶液２１ｂが伝わるのを防ぐことができる。しかし、ワックスや糊の垢がフィルター製造装置に付着するため量産化は困難である。 This problem can be prevented by applying wax or glue to the inside of the liquid-impermeable forming paper 27 and closing the gap between the inside of the forming paper 27 and the filter plug 25 to prevent the internal solution 21b from being transmitted. However, mass production is difficult because wax and glue deposits adhere to the filter manufacturing apparatus.

　以下、本発明の実施例を説明する。 Hereinafter, examples of the present invention will be described.
　図３は本実施例で作製したシガレット用フィルターの寸法を示す斜視図である。アセテートからなるたばこロッド側および吸口側の２つのフィルターロッド２５の周囲には素材紙（図示せず）が巻かれている。２つのフィルターロッド２５は互いに離間し中空部を介して配置され、その周囲に液体不透過性（耐油性）の成形紙２７が巻かれる。２つのフィルターロッド２５の間の中空部に香料カプセル２１が配置される。香料カプセル２１は皮膜２１ａで内容液２１ｂを包み込んだ構造を有する。たばこロッド側のフィルターロッド２５の長さＬ１は１１．０ｍｍ、吸口側のフィルターロッド２５の長さＬ２は１０．０ｍｍ、中空部の長さＳは６．０ｍｍ、全長ＴＬは２７．０ｍｍであり、香料カプセル２１の直径Ｄは４．５ｍｍである。本発明においては、香料カプセル２１の内容液２１ｂが３０ｍＰａ・ｓ以上の粘度を有する。 FIG. 3 is a perspective view showing dimensions of the cigarette filter produced in this example. Material paper (not shown) is wound around the two filter rods 25 on the tobacco rod side and the suction side made of acetate. The two filter rods 25 are spaced apart from each other and disposed through a hollow portion, and a liquid-impermeable (oil-resistant) forming paper 27 is wound around the filter rod 25. The fragrance capsule 21 is disposed in the hollow portion between the two filter rods 25. The fragrance capsule 21 has a structure in which the content liquid 21b is wrapped with a film 21a. The length L1 of the filter rod 25 on the tobacco rod side is 11.0 mm, the length L2 of the filter rod 25 on the suction side is 10.0 mm, the length S of the hollow portion is 6.0 mm, and the total length TL is 27.0 mm. The diameter D of the fragrance capsule 21 is 4.5 mm. In the present invention, the content liquid 21b of the fragrance capsule 21 has a viscosity of 30 mPa · s or more.
　香料カプセルの製造方法は特に限定されないが、たとえば滴下法を用いればシームレスな皮膜を有する香料カプセルを製造できるので好ましい。この方法では、二重ノズルを用い、内側ノズルから内容液を、外側ノズルから液状の皮膜物質を同時に吐出させることにより、皮膜液が継ぎ目なく内容液を包み込むことができる。 The method for producing the fragrance capsule is not particularly limited, but it is preferable to use, for example, a dropping method because a fragrance capsule having a seamless film can be produced.

　例４
　上記の例１～３の試験では、香料カプセルの皮膜をつぶして、通常の喫煙時間である１０分以内にチップペーパーの表面、たばこロッドの巻紙およびフィルター吸口端面への内容液の染み出しを調べた。しかし、香料カプセルの皮膜をつぶした後により長時間が経過した後にも、たばこロッドの巻紙への内容液の染み出しが少ないことが好ましい。そこで、以下のようにして、長時間経過後の内容液の染み出しを調べた。なお、以下の試験ではカプセルの内容液に香料を含ませていない。 Example 4
In the tests of Examples 1 to 3 above, the perfume capsule film was crushed, and the exudation of the liquid content on the tip paper surface, cigarette rod paper and filter suction end face was examined within 10 minutes, the normal smoking time. It was. However, it is preferable that the content liquid oozes out from the cigarette rod to the wrapping paper even after a longer period of time has elapsed after crushing the film of the fragrance capsule. Therefore, the exudation of the contents after a long time was examined as follows. In the following tests, no fragrance is contained in the capsule content liquid.
　サンプルＬ

Prepare capsule contents by mixing 60%, 50%, or 40% by weight of medium chain triglyceride (MCT) as solvent and 40%, 50%, or 60% by weight of SAIB as thickener. did.
　これらの内容液の粘度を回転式粘度計（東機産業（株）ＴＶＢ－１０Ｍ）により測定した。表３にカプセル内容液の組成および粘度を示す。 The viscosities of these contents were measured with a rotary viscometer (Toki Sangyo Co., Ltd. TVB-10M). Table 3 shows the composition and viscosity of the capsule content liquid.
　皮膜物質としてでんぷん、デキストリンおよび多糖類の混合物２０重量％と、上記の内容液８０重量％とを混合し、滴下法により直径４．５ｍｍのカプセルを作製した。このカプセルを用い、図３に示すシガレット用フィルターを製造し、さらに図２（ａ）と同様のシガレットを製造した。 As a film substance, 20% by weight of a mixture of starch, dextrin and polysaccharide and 80% by weight of the above-mentioned content liquid were mixed, and a capsule having a diameter of 4.5 mm was prepared by a dropping method. Using this capsule, a cigarette filter shown in FIG. 3 was produced, and a cigarette similar to that shown in FIG.
　上記のサンプルＬ～Ｐのシガレットについて、カプセルの皮膜をつぶして、１週間後にたばこロッドの巻紙への内容液の染み出しを調べた。この場合、内容液の染み出し長さは、一方のフィルタープラグ２５に接するたばこロッド１０の末端から測定して、巻紙へ染み出した内容液が達した位置までの距離を意味する。その結果を表３に併記する。 For the above sample L to P cigarettes, the capsule film was crushed, and after one week, the leakage of the content liquid onto the cigarette rod paper was examined. In this case, the leaching length of the content liquid means the distance to the position where the content liquid oozed out to the wrapping paper has been measured from the end of the tobacco rod 10 in contact with one filter plug 25. The results are also shown in Table 3.
　また、図５は、サンプルＭ～Ｐについて、内容液の粘度と内容液の染み出し長さとの関係を示すグラフである。 FIG. 5 is a graph showing the relationship between the viscosity of the contents liquid and the length of the contents liquid oozed for samples M to P.
　表３に示されるように、増粘剤を含まないサンプルＬの場合、調査した１０本の全てで、１週間後に内容液の染み出し長さが５７ｍｍとなり、内容液がたばこロッド先端の巻紙まで達した。これに対して、増粘剤として菜種油またはＳＡＩＢを用いた場合、１週間後でも内容液がたばこロッド先端の巻紙まで達することはなかった。また、表３および図５から、内容液の粘度が同じであったとしても、菜種油よりもＳＡＩＢの方が、内容液の染み出し長さが短いことがわかる。 As shown in Table 3, in the case of sample L not containing the thickener, the exudation length of the content liquid became 57 mm after 1 week in all 10 investigated, and the content liquid reached the wrapping paper at the tip of the tobacco rod. Reached. On the other hand, when rapeseed oil or SAIB was used as a thickener, the content liquid did not reach the end of the cigarette rod even after one week. Further, it can be seen from Table 3 and FIG. 5 that even when the viscosity of the content liquid is the same, SAIB has a shorter leaching length of the content liquid than rapeseed oil.
　内容液の染み出し長さが長いと、ペーパークロマトグラフ現象によって巻紙に浸透した内容液の成分が分離するという問題が生じることがある。これに対して、増粘剤としてＳＡＩＢを含む内容液は、１週間後でも染み出し長さが短いので、ペーパークロマトグラフ現象による内容液の成分の分離を抑制することができる。
Figure JPOXMLDOC01-appb-T000003
 When the seepage length of the content liquid is long, there may be a problem that the components of the content liquid that have penetrated into the wrapping paper are separated due to the paper chromatographic phenomenon. On the other hand, since the content liquid containing SAIB as a thickener has a short bleed-out length even after one week, separation of the components of the content liquid due to the paper chromatographic phenomenon can be suppressed.
