Definitions
- the present invention relates to materials for smoking articles, smoking articles, and smoking systems.
- Materials for smoking articles include hydrophobic substances. It is not easy to simply mix and disperse hydrophobic substances with other components, so a method is known in which the hydrophobic substance is dissolved in a hydrophobic solvent and the solution is sprayed onto the other components. Solvents that can be safely used in this case include, for example, ethyl alcohol, benzyl alcohol, various fatty acids, triacetin, and medium-chain fatty acid esters. However, when ethanol is used as the solvent, the solubility of the hydrophobic substance may not be sufficient. When fatty acids or medium-chain fatty acid esters are used as the solvent, the solubility problem is resolved.
- the solvent itself has low volatility, so the solvent remains, affecting the flavor when the flavor is inhaled. Furthermore, when a hydrophobic solvent is used, if the water content of the other components is high, a homogeneous mixture cannot be obtained.
- Another method is to disperse a hydrophobic substance in water and spray it on other ingredients.
- Methods for dispersing a hydrophobic substance in water include 1) mechanically forming an emulsion, 2) forming an emulsion using an emulsifier, and 3) using an inclusion compound such as cyclodextrin (Patent Document 1, Non-Patent Document 1).
- Patent Document 1 the stability of the emulsion is limited, and as a result, problems such as non-uniformity of the molded body and clogging of the fluid nozzle when spraying the emulsion often occur.
- method 2) the coexistence of an emulsifier affects the flavor.
- the inclusion compound is often expensive, and the host molecule may have an undesirable effect on the flavor when smoking.
- the hydrophobic substance when the hydrophobic substance is solid, the solid is mixed with other solid materials as it is.
- the hydrophobic substance and the other solid materials it is desirable for both the hydrophobic substance and the other solid materials to be in powder form, a state generally called powder mixing, in order to obtain a uniform molded product.
- powder mixing problems often occur in that the additive and the additive are not mixed uniformly due to the ratio of the amount of the additive and the additive, the particle size distribution of the two, and differences in specific gravity.
- 5) when the hydrophobic substance is liquid the liquid is mixed with other components as it is. This method is expected to achieve a more uniform dispersion than mixing solids together, but there is a problem that some of the components may solidify.
- a method of using an anti-caking agent in combination is also considered, but there are safety issues and the anti-caking agent itself may have an undesirable effect on the flavor.
- 6) a method is used in which the hydrophobic substance is formulated into a powder formulation using an excipient, and the other solid materials are mixed in a state that makes it easy to mix with the powder, and then the molded product is obtained.
- the hydrophobic component is heated above its melting point, melted, mixed with the excipient, and stirred. In this method, the dispersibility of the hydrophobic substance is highly dependent on its physical properties such as viscosity.
- the objective of the present invention is to provide a material for smoking articles that has good dispersibility for hydrophobic substances.

- the mixing ratio of tobacco extract to citrus fiber weight exceeded 80%, the generation of lumps became significant, and the suitability for the subsequent process was impaired. That is, it was confirmed that the content of tobacco extract is desirably 80% by weight or less, and more preferably 25% by weight or less, relative to component A (citrus fiber).
- Example 3 The molded bodies were manufactured as follows: The tobacco extract used below was prepared in the same manner as in Example 1. 1) Molded body 1 The tobacco extract prepared as component B and citrus fiber as component A were prepared. 1% by weight of the tobacco extract was mixed with the citrus fiber to obtain a powder. 10 g of the powder, 30 g of pulp fiber, and 30 g of hydroxypropyl cellulose were mixed. This mixture was mixed in small portions with 700 mL of water to obtain a slurry. The slurry was spread into a thin layer and dried to obtain a uniform sheet-like molded product. This molded product substantially contained 0.14% by weight of the tobacco extract.
- Molded body 2 The tobacco extract used in the molded body 1 was prepared as component B, and citrus fiber was prepared as component A. 20% by weight of the tobacco extract was mixed with the citrus fiber to obtain a powder. 20 g of the powder was mixed with 45 g of cellulose fiber and 1.5 g of carboxymethyl cellulose. 30 mL of water was further added to this mixture and mixed and stirred. The mixture was kneaded to prepare a block-shaped solid, which was then rolled into a sheet and dried to obtain a uniform sheet-shaped molded body. This molded body essentially contained 5.0% by weight of the tobacco extract.
- Molded body 3 The tobacco extract used in the molded body 1 was prepared as component B, and citrus fiber was prepared as component A. 10% by weight of the tobacco extract was mixed with the citrus fiber to obtain a powder. 10 g of the powder was mixed with 30 g of pulp fiber and 30 g of hydroxypropyl cellulose. This mixture was mixed in small portions with 700 mL of an aqueous solution containing 30 g of glycerin to obtain a slurry. The slurry was spread into a thin layer and dried to obtain a uniform molded body. This molded body contained substantially 0.91% by weight of the tobacco extract.
- Molded body 4 The tobacco extract used in the molded body 1 was prepared as component B, and citrus fiber and menthol were prepared as component A. 5% by weight of the tobacco extract and 4% by weight of menthol were mixed with the citrus fiber to obtain a powder. 20 g of the powder was mixed with 45 g of cellulose fiber and 1.5 g of carboxymethylcellulose, and 20 mL of water was added and mixed and stirred. The mixture was kneaded to prepare a block-shaped solid, which was then rolled into a sheet and dried to obtain a uniform sheet-shaped molded body.

1.喫煙物品用材料
喫煙物品用材料とは、喫煙物品に使用される材料である。本実施形態にかかる喫煙物品用材料は、疎水性物質と非パルプ繊維を含む。
非パルプ繊維は賦形剤としての機能を有する。非パルプ繊維(以下、成分Aともいう。)とはパルプ繊維以外の繊維である。パルプ繊維とは、木材等の植物から取り出されたセルロース繊維の集合体であり、通常は紙の原料として用いられる。パルプ繊維としては、古紙パルプ、化学パルプ、機械パルプ等が挙げられる。また、パルプ繊維は、通常のセルロース繊維または結晶セルロース繊維を含む。
喫煙物品用材料における疎水性物質は、好ましくは香味源の機能を担う。すなわち疎水性物質(以下、成分Bともいう)は、疎水性香味物質である。疎水性物質の量は、所望の香味を発現できる量であれば限定されないが、喫煙物品用材料中、好ましくは0.01~16重量%、より好ましくは0.05~6重量%である。
バインダー(以下、成分Cともいう。)は喫煙物品用材料に強度を付与する。バインダーとしては公知のものが用いられるが、例えば、セルロース誘導体、キサンタンガム、グァーガム、カラギーナン、ローカストビーンガム、アルギン酸、アルギン酸ナトリウム、でんぷん、水溶性大豆多糖類、およびこれらの組合せからなる群より選択されることが好ましい。セルロース誘導体としては、アルキルセルロース、ヒドロキシアルキルセルロースまたはカルボキシアルキルセルロースが挙げられる。セルロース誘導体としては、より具体的に、メチルセルロース、ヒドロキシエチルメチルセルロース(HEMC)、ヒドロキシプロピルメチルセルロース(HPMC)、ヒドロキシプロピルセルロース(HPC)、カルボキシメチルセルロース(CMC)、およびこれらの塩を挙げることができる。中でも、ヒドロキシプロピルメチルセルロース(HPMC)とカルボキシメチルセルロース(CMC)を併用することが好ましい。
エアロゾル源(以下、成分Dともいう)は、加熱によってエアロゾルを形成する物質である。エアロゾル源としては、グリセリンまたはポリエチレングリコール等の多価アルコールが挙げられる。喫煙物品用材料における成分Dの量は好ましくは8~50重量%、より好ましくは10~30重量%である。当該量が下限値未満であると、喫煙時の煙量が十分でない。当該量が上限値を超えると、喫煙物品用材料の取扱性が低下する。
喫煙物品用材料は、好ましくは成分A以外の繊維(以下成分Fともいう)を含む。繊維としては、例えばパルプに代表される木材繊維やセルロース繊維が挙げられる。成分Fは、喫煙物品用材料を補強する機能を担う。かかる観点から、一態様において、喫煙物品用材料中の成分Fの含有量は20~80重量%である。
喫煙物品用材料は、当該材料中に成分Bが良好に分散されており、かつ優れた成形性を備える。このため、喫煙物品用材料は、喫煙物品用の充填材に好適である。喫煙物品用材料は、刻、シート、ストランド、粉体、または顆粒の形態であってよい。
喫煙物品用材料は、任意の方法で製造されうるが、好ましくは以下の工程を備える方法で製造される。
非パルプ繊維(成分A)と、疎水性物質(成分B)と、を混合して混合物を得る混合工程、
当該混合物を、粉砕、造粒、またはシート化する成形工程。
成分Aと成分Bとを優先的に混合することで、その他の成分を混合しても、成分Bが偏在せず、混合物中で良好な分散状態を得ることができる。この理由は限定されないが、成分Aに成分Bが担持されるためではないかと推察される。混合比は、最終的な喫煙物品用材料によって適宜調整されるが、一態様において、好ましくは成分A:成分B=100:1~30(重量比)であり、より好ましくは成分A:成分B=100:1~25(重量比)である。
必要に応じて、前記混合工程の後に、成分Aと成分Bの混合物と、前述の他の成分(成分C~F)を混合する工程を設けてもよい。混合比は、最終的な喫煙物品用材料によって適宜調整される
本工程では、前工程で得た混合物を成形する。成形としては、粉砕、造粒、またはシート化が挙げられる。粉砕は公知の粉砕機を用いて実施できる。造粒は、例えば、前記混合物に水を加えて混練し、得られた混練物を湿式押出し造粒機で造粒(長柱状)した後、短柱状あるいは球状に整粒することにより得ることができる。
圧延法によりシートを製造する方法としては、例えば、以下の工程を含む方法を挙げることができる。
1)水を含む前記混合物を圧延ローラーに投入して圧延する工程。
2)圧延成形品を乾燥機で乾燥する工程。
この方法でシートを製造する場合、目的に応じて、圧延ローラーの表面を加温または冷却してもよく、圧延ローラーの回転数を調整してもよい。また、圧延ローラーの間隔を調整してもよい。所望の坪量のシートを得るために1つ以上の圧延ローラーを用いることができる。
例えば、以下の工程を含む方法を挙げることができる。
1)水を含む前記混合物(スラリー)を薄く延ばす(キャストする)工程、
2)前記キャストされたシートを乾燥する工程。
この方法でシートを製造する場合、スラリーに対して紫外線照射もしくはX線照射することで、ニトロソアミン等の一部の成分を除去する工程を加えてもよい。
例えば、以下の工程を含む方法を挙げることができる。
1)水を含む前記混合物を圧展またはダイから押出してウェットシートを調製する工程。33)前記ウェットシートを乾燥する工程。
前述のとおり、喫煙物品用材料は喫煙物品の充填剤として好適である。喫煙物品としては、燃焼型喫煙物品、非燃焼加熱型喫煙物品が挙げられる。ここでは、非燃焼加熱型喫煙物品を例にして説明する。図1に非燃焼加熱型喫煙物品の一態様を示す。図に示すように、非燃焼加熱型喫煙物品20は、たばこセグメント20Aと、周上に穿孔を有する筒状の冷却部20Bと、フィルター部20Cと、を備える。非燃焼加熱型喫煙物品20は、これ以外の部材を有していてもよい。非燃焼加熱型喫煙物品20の軸方向の長さは限定されないが、40~90mmであることが好ましく、50~75mmであることがより好ましく、50~60mm以下であることがさらに好ましい。また、非燃焼加熱型喫煙物品20の周の長さは16~25mmであることが好ましく、20~24mmであることがより好ましく、21~23mmであることがさらに好ましい。例えば、たばこセグメント20Aの長さは20mm、冷却部20Bの長さは20mm、フィルター部20Cの長さは7mmである態様を挙げることができる。これら個々の部材長さは、製造適性、要求品質等に応じて、適宜変更できる。図1には、第1セグメント25を配置した態様を示すが、これを配置せずに、冷却部20Bの下流側に第2セグメント26のみを配置してもよい。
たばこセグメント20A中のたばこ充填物21は、前記喫煙物品用材料を含む。たばこ充填物21をラッパー22内に充填する方法は特に限定されないが、例えばたばこ充填物21をラッパー22で包んでもよく、筒状のラッパー22内にたばこ充填物21を充填してもよい。たばこ充填物の形状が矩形状のように長手方向を有する場合、当該長手方向がラッパー22内でそれぞれ不特定の方向となるように充填されていてもよく、たばこセグメント20Aの軸方向に整列またはこれに直交する方向に整列させて充填されていてもよい。たばこセグメント20Aが加熱されることにより、たばこ充填物21に含まれるたばこ成分、エアロゾル源および水が気化し、吸引に供される。
冷却部20Bは筒状部材で構成されることが好ましい。筒状部材は例えば厚紙を円筒状に加工した紙管23であってもよい。また、冷却部20Bは、チャネルを形成するために、しわ付けされ、次いでひだ付け、ギャザー付け、または折畳まれた薄い材料のシートによって形成されてもよい。このような材料として、例えば、ポリエチレン、ポリプロピレン、ポリ塩化ビニル、ポリエチレンテレフタレート、ポリ乳酸、酢酸セルロース、およびアルミニウム箔から構成される群から選択されたシート材料を用いることができる。冷却部20Bの全表面積は冷却効率を考慮して適宜調製されるが、例えば、300~1000mm2/mmとすることができる。冷却部20Bには、好ましくは穿孔24が設けられる。穿孔24の存在により、吸引時に外気が冷却部20B内に導入される。これにより、たばこセグメント20Aが加熱されることで生成したエアロゾル気化成分が外気と接触し、その温度が低下するため液化し、エアロゾルが形成される。穿孔24の径(差し渡し長さ)は特に限定されないが、例えば0.5~1.5mmであってもよい。穿孔24の数は特に限定されず、1つでも2つ以上でもよい。例えば穿孔24は冷却部20Bの周上に複数設けられていてもよい。
フィルター部20Cの構成は特に限定されないが、単数または複数の充填層から構成されてよい。充填層の外側は一枚または複数枚の巻紙で巻装されてよい。フィルター部20Cの通気抵抗は、フィルター部20Cに充填されるフィルター充填物の量、材料等により適宜変更することができる。例えば、フィルター充填物が酢酸セルロース繊維である場合、フィルター部20Cに充填される酢酸セルロース繊維の量を増加させれば、通気抵抗を増加させることができる。フィルター充填物が酢酸セルロース繊維である場合、酢酸セルロース繊維の充填密度は0.13~0.18g/cm3であることができる。前記通気抵抗は通気抵抗測定器(商品名:SODIMAX、SODIM製)により測定される値である。

たばこ原料を、定法に従い有機溶媒を用いた抽出に供した。溶媒として、ヘキサン、酢酸エチル、アセトンをそれぞれ用いた。得られた各有機相(溶液)を、減圧下で濃縮して乾固させて、半固形状のたばこ抽出物を得た。これらの抽出物を濃縮乾固させた後は、エチルアルコールや水に再溶解しなかった。
非パルプ繊維(成分A):シトラスファイバー
バインダー(成分C):カルボキシメチルセルロース(CMC)、ヒドロキシプロピルセルロース(HPC)
成分A以外の繊維(成分F):結晶セルロース繊維、セルロース繊維
成分Aとして、シトラスファイバー、成分Bの疎水性物質として実施例1と同様の方法で調製したたばこ抽出物を準備した。シトラスファイバーに対し、たばこ抽出物を1~200重量%の任意の範囲で加え、混合攪拌した。たばこ抽出物は予め80℃で加温して少量ずつ投入した。混合後、撹拌翼を用いて粉体全体の色相のムラがなくなるまで攪拌混合した。シトラスファイバー重量に対する、たばこ抽出物の混合割合が25重量%までは、混合粉体中にダマの発生が少なく、後の工程に適した操作性を有すると予想された。他方、シトラスファイバー重量に対するたばこ抽出物の混合割合が25重量%から80重量%までの場合、許容範囲ではあるがダマの発生が確認された。シトラスファイバー重量に対するたばこ抽出物の混合割合が80%を超えた場合、ダマの発生が著しくなり、その後の工程への適性が損なわれた。すなわち、成分A(シトラスファイバー)に対し、たばこ抽出物の含有量は80重量%以下が望ましく、さらに好ましくは25重量%以下であることが確認された。
以下のとおりに成形体を製造した。以下で使用するたばこ抽出物は、実施例1と同様の方法で調製された。
1)成形体1
成分Bとして調製したたばこ抽出物と、成分Aとしてシトラスファイバーを準備した。シトラスファイバーに対し、1重量%のたばこ抽出物を混合して粉体を得た。当該粉体10g、パルプ繊維30g、ヒドロキシプロピルセルロース30gを混合した。この混合物を700mLの水に少量ずつ混合してスラリーを得た。スラリーを薄層に延ばして乾燥したところ、均一なシート状成形体を得た。この成形体は実質的にたばこ抽出物を0.14重量%含有する。
成分Bとして成形体1で用いたたばこ抽出物と、成分Aとしてシトラスファイバーを準備した。シトラスファイバーに対し、20重量%のたばこ抽出物を混合して粉体を得た。当該粉体20gと、セルロース繊維45g、カルボキシメチルセルロース1.5gを混合した。この混合物にさらに水を30mL加えて混合攪拌した。混合物を混錬してブロック状の固形物を調製し、圧延してシート状にした後、乾燥して均一なシート状成形体を得た。この成形体は実質的にたばこ抽出物を5.0重量%含有する。
成分Bとして成形体1で用いたたばこ抽出物と、成分Aとしてシトラスファイバーを準備した。シトラスファイバーに対し、10重量%のたばこ抽出物を混合して粉体を得た。当該粉体10gと、パルプ繊維30g、ヒドロキシプロピルセルロース30gを混合した。この混合物を、グリセリン30gを含有する700mLの水溶液に少量ずつを混合してスラリーを得た。このスラリーを薄層に延ばして乾燥したところ、均一な成形体を得た。この成形体は実質的にたばこ抽出物を0.91重量%含有する。
成分Bとして成形体1で用いたたばこ抽出物と、成分Aとしてシトラスファイバー、およびメントールを準備した。シトラスファイバーに対して、5重量%のたばこ抽出物および4重量%のメントールをそれぞれ混合して粉体を得た。当該粉体20gと、セルロース繊維45g、カルボキシメチルセルロース1.5gを混合し、さらに水を20mL加えて混合撹拌した。混合物を混錬してブロック状の固形物を調製し、圧延してシート状にした後、乾燥して均一なシート状成形体を得た。この成形体は実質的にたばこ抽出物を1.4重量%、メントールを約重量1%含有する。
