Description

フィルタ付きシガレットCigarette with filter
　本発明は、フィルタ付きシガレットに関する。 The present invention relates to a cigarette with a filter.
　シガレットは、葉タバコ等の香味をたのしむ代表的な喫煙物品である。近年では、喫煙者の嗜好の多様化に応えるべく、シガレットの種々の部位に、タバコ刻が与える香喫味とは異なる感覚刺激剤を添加することが行われている。例えば、特許文献１は、シガレットロッドとフィルタロッドを接続するチップペーパーに冷感剤を添加することを開示している。チップペーパーに添加された冷感剤は、喫煙時にチップペーパーと接触する喫煙者の唇に直接冷感を与えることにより、喫煙者に持続的な爽快感を感じさせることができる。 Cigarette is a typical smoking article that enjoys flavors such as leaf tobacco. In recent years, in order to respond to diversification of smoker's preference, a sensory stimulant different from the savory taste given by the tobacco cut is added to various parts of the cigarette. For example, Patent Document 1 discloses adding a cooling sensation agent to chip paper connecting a cigarette rod and a filter rod. The cooling sensation agent added to the chip paper can give the smoker a feeling of continuous refreshment by directly giving a cool feeling to the lips of the smoker that comes into contact with the chip paper during smoking.
日本国特開２００９－１４８２３３号Japanese Unexamined Patent Publication No. 2009-148233
　しかしながら、感覚刺激剤を添加したチップペーパーを備えるフィルタ付きシガレットは、保存中に、感覚刺激剤がチップペーパーから、シガレットの他の部位、特にフィルタ中に移行し、チップペーパー上の感覚刺激剤の量が減少してしまう。その結果、喫煙者の唇に直接付与される感覚刺激が弱まる。 However, a cigarette with a filter comprising a chip paper to which a sensory stimulant has been added, during storage, the sensory stimulant migrates from the chip paper to other parts of the cigarette, particularly into the filter, and the sensory stimulant on the chip paper The amount will decrease. As a result, sensory stimulation directly applied to the smoker's lips is weakened.
　従って、本発明の目的は、チップペーパーに添加された感覚刺激剤のフィルタへの移行が有意に抑制されたフィルタ付きシガレットを提供することである。 Therefore, an object of the present invention is to provide a cigarette with a filter in which migration of a sensory stimulant added to chip paper to a filter is significantly suppressed.
　本発明によると、タバコ刻をシガレット巻紙によりロッド状に包んだシガレットロッドと、前記シガレットロッドの一端面に設けられた、フィルタ素材をフィルタ巻取紙によりロッド状に包んだフィルタロッドと、前記フィルタロッドの外周面を覆うとともに前記シガレットロッドの外周面を部分的に覆うチップペーパーとを備え、前記チップペーパーは、感覚刺激剤を担持し、前記フィルタ巻取紙が感覚刺激剤難透過性であるフィルタ付きシガレットが提供される。 According to the present invention, a cigarette rod in which cigarettes are wrapped in a rod shape with cigarette wrapping paper, a filter rod provided on one end surface of the cigarette rod in which the filter material is wrapped in a rod shape with filter winding paper, and the filter rod A chip paper covering the outer peripheral surface and partially covering the outer peripheral surface of the cigarette rod, the chip paper carrying a sensory stimulant, and the filter cigarette is a sensory stimulant hardly permeable cigarette Provided.
　本発明のフィルタ付きシガレットにおいては、チップペーパーに添加された感覚刺激剤のフィルタへの移行が有意に抑制される。 In the cigarette with a filter of the present invention, migration of the sensory stimulant added to the chip paper to the filter is significantly suppressed.
図１は、本発明の一つの実施形態に係るフィルタ付きシガレットを示す概略断面図である。FIG. 1 is a schematic sectional view showing a cigarette with a filter according to one embodiment of the present invention.
　以下、本発明の種々の実施の形態を説明する。 Hereinafter, various embodiments of the present invention will be described.
　本発明の一実施形態に係るフィルタ付きシガレットは、シガレットロッドと、フィルタロッドと、チップペーパーを備える。シガレットロッドは、タバコ刻と、このタバコ刻をシガレット状（通常、円柱状）に包むシガレット巻紙を備える。フィルタロッドは、フィルタ素材と、このフィルタ素材をロッド状（通常、円柱状）に包むフィルタ巻取紙を備える。フィルタロッドは、シガレットロッドの一端面に、チップペーパーにより取り付けられている。チップペーパーは、フィルタロッド（より詳しくはフィルタ巻取紙）の外周を覆い、かつシガレットロッド（より詳しくはシガレット巻紙）の外周を部分的に覆っている。 A cigarette with a filter according to an embodiment of the present invention includes a cigarette rod, a filter rod, and chip paper. The cigarette rod includes cigarettes and cigarette paper that wraps the cigarettes in a cigarette shape (usually a cylindrical shape). The filter rod includes a filter material and a filter web that wraps the filter material in a rod shape (usually a cylindrical shape). The filter rod is attached to one end surface of the cigarette rod by chip paper. The chip paper covers the outer periphery of the filter rod (more specifically, the filter web) and partially covers the outer periphery of the cigarette rod (more specifically, the cigarette paper).
　シガレットロッドを構成するタバコ刻およびシガレット巻紙は、通常のシガレットに使用されているタバコ刻およびシガレット巻紙と同じである。 The tobacco engraving and cigarette wrapping paper constituting the cigarette rod are the same as the cigarette engraving and cigarette wrapping paper used in ordinary cigarettes.
　チップペーパーも、通常のフィルタ付きシガレットに使用されているチップペーパーと同じであるが、本発明においては、感覚刺激剤を担持している。感覚刺激剤としては、冷感剤が好ましい。冷感剤は、例えば、３－ｌ－メントキシプロパン－１，２－ジオール、Ｎ－エチル－ｐ－メンタン－３－カルボキサミド、３－ｌ－メントキシ－２－メチルプロパン－１，２－ジオール、メントール、メントン、カンファー、プレゴール、イソプレゴール、シネオール、ハッカオイル、ペパーミントオイル、スペアーミントオイル、ユーカリプタスオイル、ｐ－メンタン－３，８－ジオール、２－ｌ－メントキシエタン－１－オール、３－ｌ－メントキシプロパン－１－オール、４－ｌ－メントキシブタン－１－オール、３－ヒドロキシブタン酸メンチル、乳酸メンチル、メントングリセリンケタール、２－（２－ｌ－メンチルオキシエチル）エタノール、グリオキシル酸メンチル、１－（２－ヒドロキシ－４－メチルシクロヘキシル）エタノン、Ｎ－メチル－２，２－イソプロピルメチル－３－メチルブタンアミド、２－ピロリドン－５－カルボン酸メンチル、２－イソプロピル－Ｎ－２，３－トリメチルブチルアミド１，２－プロパンジオールからなる群より選択することができる。冷感剤のような感覚刺激剤は、チップペーパーに塗布することができる。 The tip paper is the same as the tip paper used for a cigarette with a normal filter, but in the present invention, it carries a sensory stimulant. As the sensory stimulant, a cooling agent is preferred. Cooling sensitizers include, for example, 3-l-menthoxypropane-1,2-diol, N-ethyl-p-menthane-3-carboxamide, 3-l-menthoxy-2-methylpropane-1,2-diol, Menthol, Mentone, Camphor, Pregol, Isopulegol, Cineol, Peppermint oil, Peppermint oil, Spare mint oil, Eucalyptus oil, p-menthane-3,8-diol, 2-l-menthoxyetan-1-ol, 3-l -Mentoxypropan-1-ol, 4-l-menthoxybutan-1-ol, menthyl 3-hydroxybutanoate, menthyl lactate, menthine glycerol ketal, 2- (2-l-menthyloxyethyl) ethanol, glyoxylic acid Menthyl, 1- (2-hydroxy-4-methylcyclohexyl) ethane N-methyl-2,2-isopropylmethyl-3-methylbutanamide, menthyl 2-pyrrolidone-5-carboxylate, 2-isopropyl-N-2,3-trimethylbutyramide 1,2-propanediol You can select from a group. Sensory stimulants such as cooling sensations can be applied to the chip paper.
　フィルタロッドを構成するフィルタ素材は、通常のフィルタ付きシガレットに使用されているフィルタ素材と同じであり得る。そのようなフィルタ素材には、セルロースアセテート繊維のトウが含まれる。セルロースアセテート繊維のトウは、トリアセチンのような可塑剤を５～１０重量％の割合で含んでいてもよい。しかしながら、フィルタ素材は、可塑剤を含んでいない、すなわち可塑剤フリーであることが好ましい。可塑剤は、感覚刺激剤を吸着し、感覚刺激を弱める傾向にある。可塑剤フリーのフィルタ素材としては、（可塑剤を含まない）セルロースアセテート繊維のトウ、ペーパー等を例示することができる。 The filter material constituting the filter rod can be the same as the filter material used in a normal cigarette with a filter. Such filter materials include cellulose acetate fiber tows. The tow of cellulose acetate fiber may contain 5 to 10% by weight of a plasticizer such as triacetin. However, it is preferable that the filter material does not contain a plasticizer, that is, is plasticizer-free. Plasticizers tend to adsorb sensory stimulants and weaken sensory stimuli. Examples of the plasticizer-free filter material include tow of cellulose acetate fiber (not containing a plasticizer), paper, and the like.
　フィルタ素材とともにフィルタロッドを構成するフィルタ巻取紙は、感覚刺激剤に対し難透過性、すなわち感覚刺激剤を透過させ難いものである。感覚刺激剤難透過性のフィルタ巻取紙としては、プラスチックフィルムやプラスチックフィルムと紙とのラミネート加工紙が考えられるが、これらは、通気性が悪く、例えば、１４～２０μｍのポリエチレン層を有する通常のラミネート加工紙では水分が難透過性となり従来のたばこと比べて喫味が変化してしまうこともある。また、耐油性と水蒸気透過性を有する耐油紙として知られているフッ素系化合物を用いた加工紙も考えられるが、難分解性であることから地球環境的に望ましくない。かくして、本発明に用いるフィルタ巻取紙は、感覚刺激剤を実質的に透過させないが、水蒸気透過性有し、しかも環境にやさしいグラシン紙やトレーシングペーパー、パーチメント紙（硫酸紙）等が望ましい。特に、坪量３０～６０ｇ／ｍ2の坪量を有するベース紙と、前記ベース紙の少なくとも片面に塗布された水溶性高分子物質を備え、５０，０００～３００，０００秒の通気抵抗度と２，０００～４，０００ｇ／ｍ2・２４ｈｒの透湿度を示す耐油紙をフィルタ巻取紙として用いることが好ましい。このような紙は日本国特許第４５２０１３８号に記載され、日本製紙パピリア株式会社から市販されている。日本国特許第４５２０１３８号によると、かかる耐油紙のベース紙は、ショッパーろ水度８５～９０°ＳＲの製紙用天然繊維に、光に対する屈折率が１．８～３．０の填料が繊維に対して２～１０質量％含まれているもので、５０，０００～２００，０００秒の透気抵抗度を示す。高分子物質は、酸化デンプン、リン酸エステル化デンプン、アセチル化デンプン、未変性デンプン、カルボキシメチルセルロース塩から選ぶことができ、０．２～１．０ｇ／ｍ2の割合でベース紙に塗布される。填料としては、ルチル型二酸化チタン（屈折率２．７６）、アナターゼ型二酸化チタン（屈折率２．５２）、酸化ジルコン（屈折率２．４０）、酸化亜鉛（屈折率２．０１）等の無機顔料、二酸化チタン被覆雲母（屈折率２．３）、酸化鉄被覆雲母（屈折率２．９）、二酸化チタン被覆シリカ、二酸化チタン被覆ガラスフレークのような複合顔料等が挙げられる。これらの填料は、製紙用天然繊維に対して２～１０質量％、好ましくは３～７質量％内添する。 The filter web constituting the filter rod together with the filter material is hardly permeable to the sensory stimulant, that is, it is difficult for the sensory stimulant to pass through. As the filter paper having a low permeability to the sensory stimulant, a plastic film or a laminated paper made of a plastic film and paper can be considered. However, these papers have poor air permeability and are, for example, ordinary laminates having a polyethylene layer of 14 to 20 μm. In the processed paper, moisture is hardly permeable, and the taste may be changed as compared with conventional cigarettes. In addition, a processed paper using a fluorine-based compound known as an oil-resistant paper having oil resistance and water vapor permeability can be considered, but it is not desirable in terms of the global environment because it is hardly decomposable. Thus, the filter paper used in the present invention is preferably glassine paper, tracing paper, parchment paper (sulfuric acid paper) or the like that does not substantially permeate the sensory stimulant but has water vapor permeability and is also environmentally friendly. In particular, it comprises a base paper having a basis weight of 30 to 60 g / m 2 and a water-soluble polymer substance applied to at least one side of the base paper, and has a ventilation resistance of 50,000 to 300,000 seconds. It is preferable to use an oil-resistant paper exhibiting a water vapor permeability of 2,000 to 4,000 g / m 2 · 24 hr as the filter web. Such paper is described in Japanese Patent No. 4520138 and is commercially available from Nippon Paper Papillia Co., Ltd. According to Japanese Patent No. 4520138, such an oil-resistant paper base paper is a natural fiber for papermaking with a shopper freeness of 85 to 90 ° SR, and a fiber with a refractive index of 1.8 to 3.0 for light. On the other hand, it is contained in an amount of 2 to 10% by mass and exhibits an air resistance of 50,000 to 200,000 seconds. The polymeric material can be selected from oxidized starch, phosphated starch, acetylated starch, unmodified starch, carboxymethylcellulose salt and is applied to the base paper at a rate of 0.2-1.0 g / m 2. . Examples of fillers include inorganic materials such as rutile titanium dioxide (refractive index 2.76), anatase titanium dioxide (refractive index 2.52), zircon oxide (refractive index 2.40), and zinc oxide (refractive index 2.01). Examples thereof include composite pigments such as pigments, titanium dioxide-coated mica (refractive index 2.3), iron oxide-coated mica (refractive index 2.9), titanium dioxide-coated silica, and titanium dioxide-coated glass flakes. These fillers are added in an amount of 2 to 10% by weight, preferably 3 to 7% by weight, based on natural fibers for papermaking.
　図１は、本発明の一実施の形態に係るフィルタ付きシガレット１００の概略断面図である。このフィルタ付きシガレット１００は、シガレットロッド１１０、フィルタロッド１２０およびチップペーパー１３０を備える。 FIG. 1 is a schematic cross-sectional view of a cigarette 100 with a filter according to an embodiment of the present invention. This cigarette 100 with a filter includes a cigarette rod 110, a filter rod 120, and chip paper 130.
　シガレットロッド１１０は、タバコ刻１１１をシガレット巻紙１１２によりロッド状（通常、円柱状）に包んだものである。フィルタロッド１２０は、セルロースアセテート繊維のトウなどのフィルタ素材１２１をフィルタ巻取紙１２２によりロッド状（通常、円柱状）に包んだものであり、シガレットロッドとほぼ同じ径を有する。シガレットロッド１１０とフィルタロッド１２０とは、互いに端面と端面が接しており、感覚刺激剤（図示せず）を担持したチップペーパー１３０により固定されている。チップペーパー１３０は、フィルタロッドの外周面を覆い、かつシガレットロッドの外周面を部分的に覆っている。 The cigarette rod 110 is a cigarette engraved 111 wrapped with a cigarette wrapping paper 112 in a rod shape (usually a cylindrical shape). The filter rod 120 is obtained by wrapping a filter material 121 such as a cellulose acetate fiber tow with a filter web 122 in a rod shape (usually a cylindrical shape), and has substantially the same diameter as the cigarette rod. The cigarette rod 110 and the filter rod 120 are in contact with each other at their end faces, and are fixed by a chip paper 130 carrying a sensory stimulant (not shown). The chip paper 130 covers the outer peripheral surface of the filter rod and partially covers the outer peripheral surface of the cigarette rod.

　フィルタ付きシガレットＡ～Ｃ各３本のチップペーパーに、冷感剤（Ｎ－エチル－ｐ－メンタン－３－カルボキサミド）または（３－ｌ－メントキシプロパン－１，２－ジオール）を塗布し、５５℃の恒温室に所定期間保存した。その後、チップペーパーに残った冷感剤を以下の手法により抽出し、定量した。冷感剤の初期の添加量を１００％としたときの、冷感剤の残留率（３本の平均値）を算出した。結果を下記表２に示す。 Apply a cooling sensation agent (N-ethyl-p-menthane-3-carboxamide) or (3-1-menthoxypropane-1,2-diol) to each of the three chip papers with cigarettes A to C. It was stored in a constant temperature room at 55 ° C. for a predetermined period. Thereafter, the cooling sensation agent remaining on the chip paper was extracted and quantified by the following method. When the initial amount of the cooling sensation agent was 100%, the residual rate of the cooling sensation agent (average value of three) was calculated. The results are shown in Table 2 below.
　＜冷感剤の抽出・定量手法＞
　保存後のフィルタ付きシガレットからチップペーパを切り取り、エタノール１０ｍＬを加え、１時間振盪する。振盪後の抽出液に含まれる冷感剤をＧＣ／ＭＳで定量する。

　表２に示す結果から分かるように、本発明のフィルタ付きシガレットは、冷感剤の残留率が比較例のフィルタ付きシガレットにおける冷感剤の残留率よりも大幅に高い。また、フィルタ素材として可塑剤フリーの素材を用いた場合には、上記残留率がさらに向上する。 As can be seen from the results shown in Table 2, in the cigarette with a filter of the present invention, the residual rate of the cooling sensate is significantly higher than the residual rate of the cooling sensate in the cigarette with a filter of the comparative example. Further, when a plasticizer-free material is used as the filter material, the residual rate is further improved.
