Abstract

A cigarette includes a tobacco filler material rod and a cigarette paper wrapping the rod. The cigarette paper has an inherent air permeability of more than 20 CORESTA units but 80 CORESTA units or less and contains a loading material in an amount of 1.0 to 5.0 g/m 2 .

Description

本発明は、着火されたシガレットが喫煙者の不注意等により火災を起こし難いように、火種から周囲物に延焼し難い低延焼性シガレットに関する。   The present invention relates to a low fire spread cigarette that is difficult to spread from a fire type to surrounding objects so that an ignited cigarette hardly causes a fire due to carelessness of a smoker.

シガレットが喫煙者の不注意等により床等に落下した場合、その火種から床等に延焼しにくいように、タバコ巻紙に幅が２〜２０ｍｍのセルロース紙製バンドを設けて自己消火性を付与したシガレット（特許文献１参照）や、タバコ巻紙に難燃性物質を塗布したバンドを設けたシガレット（特許文献２参照）等が提案されている。また、不燃材を貼着したタバコ巻紙も知られている。これらの技術は、タバコ巻紙に燃焼性の高い領域と燃焼性の低い領域を設けることにより、燃焼性の高い領域では通常の喫煙が行えるが、燃焼性の低い領域でシガレットが立ち消えるという知見に基づく。 When cigarettes fall on the floor etc. due to carelessness of smokers, a self-extinguishing property is provided by providing a band made of cellulose paper with a width of 2 to 20 mm on the cigarette paper so that it is difficult to spread from the fire type to the floor etc. Cigarettes (see Patent Document 1 ), cigarettes (see Patent Document 2 ) provided with a band obtained by applying a flame retardant material to cigarette paper have been proposed. In addition, cigarette paper with non-combustible material is also known. These technologies are based on the knowledge that cigarettes disappear in areas with low flammability, although normal smoking can be performed in areas with high flammability by providing areas with high flammability and areas with low flammability. Based.

また、時間当たりの副流煙量を減少させることを目的としてシガレットの燃焼速度を低下させると、立ち消えしやすいシガレットが提供できることも従来からよく知られている。かかるシガレットとして、填料の配合量の少ないシガレット巻紙を内側巻紙とし、通常のシガレット巻紙を外側巻紙としてこれらにより刻みタバコを巻装したシガレットが提案されている（特許文献３参照）。また、低副流煙シガレットとして、１００〜２６０ｍｇ／ｃｍ3の充填密度の喫煙材ロッドを７コレスタ単位以下の通気度を有する巻紙で巻装したシガレットも提案されている（特許文献４参照）。さらに、低い通気度（７コレスタ単位）で低填料量、低坪量の巻紙を用いることにより燃焼速度を低下させたシガレットも提案されている（特許文献５参照）。

As such cigarettes, cigarettes having cigarettes with a small amount of filler as inner wrapping paper and ordinary cigarette wrapping paper as outer wrapping paper and cigarettes wrapped around them have been proposed (see Patent Document 3 ). In addition, as a low sidestream smoke cigarette, a cigarette in which a smoking material rod having a packing density of 100 to 260 mg / cm 3 is wound with a wrapping paper having an air permeability of 7 cores or less has been proposed (see Patent Document 4 ). Furthermore, a cigarette having a low air permeability (7 coresta units) and a low filler amount and a low basis weight is used to reduce the burning rate (see Patent Document 5 ).

しかしながら、不燃性の領域が存在する巻紙を用いる場合には、燃えにくい部分と燃えやすい部分があるという点で喫煙時に不均一な燃焼となり、また喫味も一定にならない。また、燃焼速度を下げて低延焼性を図るという方法は、巻紙の通気度を低下させることによりその目的を達成しようとしていたため、巻紙からのベンチレーション効果が低下し、主流煙中の一酸化炭素（ＣＯ）量が増加し、一酸化炭素／タール比（Ｃ／Ｔ比）が高くなる。さらに、巻紙の通気度を低下させることは、タバコの喫味変化をもたらし、通常の喫煙者にとっては違和感を感じてしまうという問題がある。   However, when using a wrapping paper in which a non-combustible region is present, non-combustible combustion occurs at the time of smoking in that there are a portion that is difficult to burn and a portion that is easy to burn, and the taste is not constant. In addition, the method of reducing the burning rate to achieve low fire spread has been aimed at achieving its purpose by lowering the air permeability of the wrapping paper, so the ventilation effect from the wrapping paper is reduced, and the monoxide in the mainstream smoke is reduced. The amount of carbon (CO) increases and the carbon monoxide / tar ratio (C / T ratio) increases. Furthermore, lowering the air permeability of the wrapping paper causes a change in the taste of the cigarette, which causes a problem that a normal smoker feels uncomfortable.

他方、填料の配合割合の小さい巻紙を用いたシガレットは、燃焼速度が低下することが知られているものの、自然燃焼中に、途中で立ち消えすることが経験的に知られており、填料の量をあまり少なくすることができなかった。   On the other hand, cigarettes using wrapping paper with a small blending ratio of filler are empirically known to disappear during the course of spontaneous combustion, although the burning rate is known to decrease. Could not be reduced too much.

従って、本発明は、通常のシガレットと同様の喫煙動作が行え、燃焼速度も通常のシガレットのそれとほぼ変わらず、しかも主流煙中のＣ／Ｔ比が改善されるとともに、低延焼性を示し得るシガレットを提供することを目的とする。   Therefore, the present invention can perform a smoking operation similar to that of a normal cigarette, the burning rate is almost the same as that of a normal cigarette, and the C / T ratio in the mainstream smoke is improved, and low flame spread can be exhibited. The purpose is to provide cigarettes.

本発明者らは、低延焼性シガレットの研究を進める中で、タバコ充填材とシガレット巻紙から構成されるシガレットにおいて、特別のバンドや難燃性物質を用いることなく、タバコ充填材ロッドを巻装するシガレット巻紙の固有通気度、および巻紙に配合される填料の量を特定の値に設定するだけで、上記目的を達成し得るシガレットを作製できることを見いだした。シガレット巻紙の固有通気度を所定の範囲内に設定することにより、自然燃焼を維持する範囲内で、填料の量を可能な限り少なくすることができる。本発明はこれらの知見に基づく。 In the process of researching low-fire-spreading cigarettes, the present inventors wound cigarette filler rods in cigarettes composed of cigarette fillers and cigarette wrapping paper without using special bands or flame retardant materials. specific air permeability of the cigarette paper wrapper which, and the amount of filler to be incorporated in cigarette paper only set to a specific value, was found to be able to produce a cigarette that can achieve the above object. By setting the inherent air permeability of the cigarette wrapping paper within a predetermined range, the amount of filler can be reduced as much as possible within the range where natural combustion is maintained. The present invention is based on these findings.

すなわち、本発明によれば、タバコ充填材のロッドと、前記ロッドを巻装するシガレット巻紙を備えるシガレットであって、前記巻紙が、３４〜５２コレスタ単位の固有通気度を有し、填料を２．４〜３．３ｇ／ｍ2の割合で含有し、１８〜２５ｇ／ｍ 2 の坪量を有し、かつ０〜０．６重量％の割合で燃焼調節剤を含有し、前記タバコ充填材が、０．８〜１．２ｍｍの幅を有するタバコ刻みからなり、かつ１４０〜２２０ｍｇ／ｃｍ3の充填密度で充填されており、前記シガレットが、一定距離自然燃焼させた後にろ紙１０枚からなる基材上に静置したとき、シガレットが燃焼を停止するまでにシガレット巻紙の炭化線がシガレット軸方向に沿って移動する距離のメジアン値が８ｍｍ以下であるような低延焼性を示すシガレットが提供される。 That is, according to the present invention, a rod of tobacco filler, a cigarette Ru comprising a cigarette paper wrapper wound around the rod, the cigarette paper has a specific air permeability of 34 to 52 Coresta units, Hama fees were contained in a proportion of 2.4~3.3g / m 2, it had a basis weight of 18-25 g / m 2, and contains a burn adjusting agent in an amount of 0 to 0.6 wt%, the tobacco 10 sheets of filter paper after the filler is made of tobacco cut having a width of 0.8 to 1.2 mm and filled with a packing density of 140 to 220 mg / cm 3 , and the cigarette is naturally burned for a certain distance. A cigarette exhibiting low fire spread such that the median value of the distance along which the carbonized wire of the cigarette paper moves along the cigarette axial direction before the cigarette stops burning when left standing on a substrate comprising Will be provided

以下、本発明をより詳しく説明する。   Hereinafter, the present invention will be described in more detail.

本発明のシガレットは、タバコ充填材ロッドと、このタバコ充填材ロッドを巻装するシガレット巻紙を備える。本発明のシガレットは、通常のシガレットと同様の外観・形状を有する。   The cigarette of the present invention includes a tobacco filler rod and a cigarette paper around which the tobacco filler rod is wound. The cigarette of the present invention has the same appearance and shape as a normal cigarette.

本発明のシガレットに用いられるタバコ充填材ロッドは、通常のタバコ刻み等からなる。タバコ刻みは、膨化タバコや再生タバコおよび中骨を含有することができる。タバコ充填材ロッドの充填密度は、１３０〜２６０ｍｇ／ｃｍ3であることが好ましい。この充填密度が、この範囲を逸脱すると、本発明のシガレット巻紙で巻装しても延焼性が十分に低下しないことがある。タバコ充填材の充填密度は、１４０〜２２０ｍｇ／ｃｍ3である。また、タバコ刻みの刻み幅は、通常使用されるタバコ刻みの幅で十分であるが、低延焼性の観点から、比較的大きい０．５〜１．５ｍｍの刻み幅が好ましく、０．８〜１．２ｍｍの刻み幅がより好ましい。 The tobacco filler rod used in the cigarette of the present invention is formed of a normal tobacco cut or the like. Tobacco cuts can contain expanded tobacco, regenerated tobacco, and midbones. The filling density of the tobacco filler rod is preferably 130 to 260 mg / cm 3 . If this filling density deviates from this range, the fire spreadability may not be sufficiently lowered even when the cigarette paper of the present invention is wound. Packing density of the tobacco filler, Ru 140 to 220 mg / cm 3 der. Further, the step size of the tobacco step is usually the width of the tobacco step used normally, but from the viewpoint of low fire spread, a relatively large step size of 0.5 to 1.5 mm is preferable, 0.8 to A step size of 1.2 mm is more preferable.

本発明に用いられるシガレット巻紙は、普通にシガレット巻紙を構成するものとして使用されている通常の亜麻パルプ等のパルプをベースとするものであり、従ってパルプを含有する。本発明に用いるシガレット巻紙の固有通気度（穿孔しないときの通常の通気度）は、３４〜５２コレスタ単位以下である。シガレット巻紙の固有通気度が２０コレスタ単位以下であると、喫煙時に発生するシガレット主流煙中のＣ／Ｔ比が高くなる。シガレット巻紙の固有通気度が８０コレスタ単位を超えると、通気度のばらつきが大きくなる。なお、シガレット巻紙には、通常の手法により、機械的にまたは電気的に穿孔することができる。このような開孔を有する巻紙の通気度には、特に制限はない。 The cigarette paper used in the present invention is based on pulp such as ordinary flax pulp which is usually used as a constituent of cigarette paper and therefore contains pulp. The inherent air permeability (normal air permeability when not perforated) of the cigarette paper used in the present invention is 34 to 52 coresta units or less. When the inherent air permeability of the cigarette paper is 20 cores or less, the C / T ratio in cigarette mainstream smoke generated during smoking increases. When the inherent air permeability of the cigarette paper exceeds 80 coresta units, the air permeability varies greatly . Contact name cigarette paper wrapper by conventional techniques, it can be mechanically or electrically the perforation. There is no restriction | limiting in particular in the air permeability of the wrapping paper which has such an opening.

本発明のシガレット巻紙は、填料を含有する。填料としては、炭酸カルシウム、炭酸カリウム等の炭酸塩、水酸化カルシウム、水酸化マグネシウム等の水酸化物のような一般に使用されているものを用いることができる。シガレット巻紙中の填料量は、２．４〜３．３ｇ／ｍ2である。填料の量が１．０ｇ／ｍ2未満であると、自然燃焼中にシガレットが立ち消えし、填料の量が５．０ｇ／ｍ2を超えると、低延焼性が達成されない。
シガレット巻紙の坪量は、１７〜２８ｇ／ｍ2であることが好ましい。坪量が１７ｇ／ｍ2未満であると、安定的な巻紙製造が困難となり、２８ｇ／ｍ2を超えると、延焼性が上がる傾向を示す。巻紙の坪量は、１８〜２５ｇ／ｍ2であることがより好ましく、１８〜２２ｇ／ｍ2であることがより好ましい。 The cigarette wrapping paper of the present invention contains a filler. As the filler, commonly used ones such as carbonates such as calcium carbonate and potassium carbonate, and hydroxides such as calcium hydroxide and magnesium hydroxide can be used. The amount of filler in the cigarette wrapping paper is 2.4 to 3.3 g / m 2 . When the amount of the filler is less than 1.0 g / m 2 , the cigarette disappears during spontaneous combustion, and when the amount of the filler exceeds 5.0 g / m 2 , low fire spreadability is not achieved .
The basis weight of the cigarette paper is preferably 17 to 28 g / m 2 . When the basis weight is less than 17 g / m 2 , stable wrapping paper production becomes difficult. When the basis weight exceeds 28 g / m 2 , the fire spreadability tends to increase. The basis weight of the wrapping paper, more preferably 18-25 g / m 2, and more preferably 18-22 g / m 2.

シガレット巻紙には、クエン酸、またはその塩（ナトリウム塩、カリウム塩）等の燃焼調節剤を添加することもできるが、その含有量は０〜１．０重量％であることが好ましい。燃焼調節剤の量が１．０重量％を超えると、Ｃ／Ｔ比が高くなる傾向を示す。燃焼調節剤の量は、０〜０．６重量％であることがより好ましく、０．１〜０．６重量％であることがさらに好ましい。   The cigarette paper may be added with a combustion regulator such as citric acid or a salt thereof (sodium salt, potassium salt), but the content is preferably 0 to 1.0% by weight. When the amount of the combustion modifier exceeds 1.0% by weight, the C / T ratio tends to increase. The amount of the combustion regulator is more preferably 0 to 0.6% by weight, and further preferably 0.1 to 0.6% by weight.

なお、本発明のシガレット巻紙は、１０〜２０Ｎ／１５ｍｍ以上の引っ張り強度を有することにより、８０００〜１２０００本／分でシガレットを製造する高速シガレット製造機に供しても何ら支障なくシガレットを製造し得る。引っ張り強度は、シガレット巻紙に使用するパルプの叩解度もしくはパルプ量を調整することにより調整することができる。パルプの叩解度が高いほど、また巻紙面積当たりのパルプ量が高いほど、引っ張り強度も高くなる。   The cigarette wrapping paper of the present invention has a tensile strength of 10 to 20 N / 15 mm or more, so that it can be produced without any problem even if it is subjected to a high-speed cigarette production machine that produces cigarettes at 8000 to 12000 pieces / min. . The tensile strength can be adjusted by adjusting the beating degree or pulp amount of pulp used for cigarette paper. The higher the degree of beating of the pulp and the higher the amount of pulp per wrapping paper area, the higher the tensile strength.

本発明では、シガレット巻紙の固有通気度、およびシガレット巻紙に含まれる填料の割合を上記範囲内に設定することにより、シガレット巻紙の固有通気度が比較的高いにも拘わらず、延焼性が低く、Ｃ／Ｔ比の小さい主流煙を発生するシガレットが得られる。また、本発明のシガレットは、通常品とほぼ同様の燃焼速度を示し得る。本発明のシガレットの低延焼性は、シガレットを一定距離自然燃焼させた後に基材（ろ紙１０枚）上に静置したとき（ＡＳＴＭ Ｅ２１８７−０２ｂ法に従って測定）、シガレットが燃焼を停止するまでにシガレット巻紙の炭化線がシガレット軸方向に沿って移動する距離のメジアン値が８ｍｍ以下、好ましくは４ｍｍ以下であるようなものである。そして、複数の本発明のシガレットにおいて、上記移動距離の最頻値は、８ｍｍ以下、好ましくは４ｍｍ以下であり得る。   In the present invention, by setting the inherent air permeability of the cigarette wrapping paper and the ratio of the filler contained in the cigarette wrapping paper within the above range, the fire spreadability is low despite the relatively high inherent air permeability of the cigarette wrapping paper, Cigarettes that generate mainstream smoke with a low C / T ratio are obtained. Moreover, the cigarette of this invention can show a burning rate substantially the same as a normal product. The low fire spreadability of the cigarette of the present invention is such that when the cigarette is naturally burned for a certain distance and then left on the substrate (10 sheets of filter paper) (measured according to the ASTM E2187-02b method), the cigarette stops burning. The median value of the distance that the carbonized wire of the cigarette paper moves along the cigarette axial direction is 8 mm or less, preferably 4 mm or less. And in the several cigarette of this invention, the mode value of the said movement distance may be 8 mm or less, Preferably it is 4 mm or less.

以下本発明を実施例により説明するが、本発明はそれらに限定されるものではない。   Hereinafter, the present invention will be described by way of examples, but the present invention is not limited thereto.

Calcium carbonate was used as a filler, and sodium citrate was used as a combustion regulator. Moreover, as the tobacco step, yellow seed step or blend step was used. Table 1 shows the inherent air permeability and tensile strength of cigarette paper. In addition, the tensile strength shown in Table 1 was measured by the method shown in Japanese Industrial Standard (JIS) P 8113-1998 using a tensile strength tester STROGRAPH ES manufactured by Toyo Seiki Co., Ltd. (size of test piece: 15.0 mm × About 250 mm, distance between grips: 180 ± 2 mm, pulling speed: 50 mm / min).

作製したシガレットについて、常法により自然燃焼速度を測定するとともに、ＡＳＴＭ Ｅ２１８７−０２ｂ法に従って、ろ紙１０枚上での全長燃焼割合（percent full length burn）を測定した。また、着火したシガレットをろ紙上に置いたとき、シガレットが燃焼を停止する（立ち消えする）までにシガレット巻紙の炭化線がシガレット軸方向に沿って移動する距離のメジアン値を測定した。結果を表２に示す。   About the produced cigarette, the natural burning rate was measured by the conventional method, and the full length burn rate (percent full length burn) on 10 filter papers was measured according to ASTM E2187-02b method. Further, when the ignited cigarette was placed on the filter paper, the median value of the distance that the carbonized wire of the cigarette wrapping paper moved along the cigarette axis direction before the cigarette stopped burning (disappeared) was measured. The results are shown in Table 2.

また、各シガレットを燃焼したときに発生するタバコ主流煙中の全粒状物質（ＴＰＭ）の量、一酸化炭素の量およびタールの量を常法により測定し、Ｃ／Ｔ値を算出した。また、パフ回数も測定した。結果を表３に示す。
