Abstract
Description
また、非燃焼加熱型喫煙物品では、その加熱温度が通常のシガレットの燃焼温度よりも低いために、発生する煙の量が少なく、通常のシガレットよりもたばこ刻みへの香料添加量を多くする必要がある。
上記のように、たばこ刻みの充填密度が高く、かつ、香料添加量の多い非燃焼加熱型喫煙物品においては、通常のシガレットと比較して、巻紙表面に香料が浮き出てしまう(染みの発生)という課題が顕著であった。
特許文献3には、シガレットを構成する、充填物とその外側巻紙の間に、特定の通気度を有する内側巻紙を配置することで、巻紙への染み発生を抑制している。この内側巻紙の坪量としては、最大でも30g/m2であることが記載されている。
また、特許文献4には、セルロース誘導体からなる撥水剤を巻紙に塗布して乾燥させることで第一の層を形成し、さらにその上にセルロース誘導体を塗布して第二の層を形成させることにより、撥水剤が含侵されてなる巻紙を形成することで、巻紙における染みの発生を抑制する方法が記載されている。
特許文献4に記載の発明は、巻紙に、セルロース誘導体のような撥水剤の二回塗工を特徴とする。こういった物質の塗工は染み発生の抑制に効果的ではあるが、十分な効果を得るためには比較的多く塗工する必要があり、香喫味品質、燃焼性、通気性に大きな影響を与えるので、設計上の自由度が損なわれることがある。
このように、巻紙の染みの発生を抑制するという観点で用いられてきた先行技術については、改良の余地があると言え、さらに、たばこ刻みの充填密度が高く、かつ、エアロゾル生成基材及び香料の添加量が多い非燃焼加熱型喫煙物品においては、先行技術以上に染みの発生が抑制された巻紙、特に、比較的大きな染みの発生が抑制された巻紙が求められる。
そこで、本発明では、染みの発生が抑制された、特に、比較的大きな染みの発生が抑制された非燃焼加熱型喫煙物品用の巻紙を提供することを課題とする。
[1]坪量が35g/m2以上であり、パルプ濾水度が69°SR以上であり、通気度が20CU以下であり、かつ、不透明度が85%以下である、非燃焼加熱型喫煙物品用の巻紙。
[2]水接触角が90°未満である、[1]に記載の非燃焼加熱型喫煙物品用の巻紙。
[3]填料を35重量%以上含む、[1]又は[2]に記載の非燃焼加熱型喫煙物品用の巻紙。
[4]たばこ刻みとエアロゾル生成基材とを含む充填物が、該充填物を巻装する第一の巻紙で巻装されてなるたばこロッド部と、該たばこロッド部とは反対側の端部を構成するマウスピース部とを有し、前記たばこロッド部と前記マウスピース部は、前記充填物を巻装する巻紙と同じ又は別の第二の巻紙を用いて連結されている非燃焼加熱型喫煙物品であって、第一の巻紙と第二の巻紙の少なくとも一方が、[1]~[3]のいずれかに記載の巻紙である、非燃焼加熱型喫煙物品。
[5]前記たばこロッド部が、たばこ刻み、及びエアロゾル生成基材を含む充填物を含み、当該充填物の密度が250mg/cm3以上であり、当該充填物中のエアロゾル生成基材の含有量が5重量%以上である、[4]に記載の非燃焼加熱型喫煙物品。
[6]前記たばこロッド部が、香料を含む充填物を含み、当該香料の含有量が10000ppm以上である、[4]又は[5]に記載の非燃焼加熱型喫煙物品。
[7]ヒーター部材と、該ヒーター部材からの熱を伝熱する伝熱部材と、該ヒーター部材の電力源となる電池ユニットと、該ヒーター部材を制御するための制御ユニットとを備える電気加熱型デバイスと、該伝熱部材に接触するように嵌合される、[4]~[6]のいずれかに記載の非燃焼加熱型喫煙物品と、から構成される、電気加熱型喫煙システム。
なお、本明細書において、「~」を用いてその前後に数値又は物性値を挟んで表現する場合、その前後の値を含むものとして用いることとする。
また、本明細書において、非燃焼加熱型喫煙物品における「加熱温度」及び通常のシガレットにおける「燃焼温度」の総称として、「喫煙温度」の表現を用いる場合もある。
また、本明細書において、気化した物質及びエアロゾル化した物質の総称として、「煙」の表現を用いる場合がある。
また、本明細書において、「染みの発生」とは、巻紙表面に、目視で認識可能な程度にたばこ刻み由来の成分や香料等が浮き出る現象を意味する。
本発明の一形態である非燃焼加熱型喫煙物品用の巻紙(以下、「本発明の一形態である巻紙」と称する場合もある)は、坪量が35g/m2以上であり、パルプ濾水度が69°SR以上であり、通気度が20CU以下であり、かつ、不透明度が85%以下である。
また、填料の平均粒径は、特に限定されず、通常3.0μm~3.5μmである。
上記範囲の下限を下回ると巻紙が焦げやすくなり、また、上限を上回ると巻紙の強度が大きく低下してしまい、数千本/分で運転されるたばこの高速製造時に紙切れが頻発し、いわゆる巻上げ適性が悪化し得る。
他にも、例えば、耐水性を向上させるために、耐水性向上剤を有することができる。耐水性向上剤には、湿潤紙力増強剤(WS剤)及びサイズ剤が含まれる。湿潤紙力増強剤の例を挙げると、尿素ホルムアルデヒド樹脂、メラミンホルムアルデヒド樹脂、ポリアミドエピクロルヒドリン(PAE)等であり、用いる場合には通常0.1重量%~2重量%で添加する。また、サイズ剤の例を挙げると、ロジン石けん、アルキルケテンダイマー(AKD)、アルケニル無水コハク酸(ASA)、ケン化度が90%以上の高ケン化ポリビニルアルコール等であり、用いる場合には通常0.1重量%~2重量%で添加する。
上記範囲内であると、染み発生を抑制し、また、適度な巻上げ適性を維持することができる。
また、巻紙の坪量は、填料の種類や含有量を調整すること等によって調製することができ、例えば、密度の高い填料を加えることにより坪量を大きくし、又は、密度の低い填料を加えることにより坪量を小さくすることができ、また、同じ密度の填料でも含有量を増減することで坪量を増減することができる。
上記範囲内であると、染み発生を抑制し、また、適度な強度を維持することができる。
また、巻紙のパルプ濾水度は、用いるパルプの濾水度を調整することにより制御でき、調整方法として例えば、パルプの蒸解や叩解の条件を変更することが挙げられる。
上記範囲内であると、染み発生を抑制し、また、適度な剛性や通気性を維持することができる。
また、巻紙の通気度は、パルプの叩解工程の条件およびパルプの含有量の制御、填料の種類や含有量の制御、抄紙工程における脱水速度、乾燥速度、カレンダー処理等の操作条件により調整することができる。
上記範囲内であると、染みの数、特に、比較的大きな染みの数を減少させることができる。また、上記範囲の上限を超えると、巻紙の白色と染みの黄茶色とのコントラストによる外観悪化が目立つようになり、上記範囲の下限を下回ると、たばこロッド中の充填物が透けることによる巻紙全体の外観悪化が生じる。
また、巻紙の不透明度は、填料の含有量を調整すること等によって調製することができ、通常、填料の含有量の増加により不透明度を増加させることができる。
巻紙の表面の水接触角を上記範囲内とするためには、巻紙の表面が疎水性でないことが好ましい。具体的には、巻紙の表面に疎水性の膜を積層する、又は疎水性の溶液を塗付する等の処理を行わないことが好ましく、より具体的には、例えば、香喫味に影響しない点で、巻紙の表面と共有結合された脂肪酸及び/又は脂肪酸エステルを含まないことが好ましい。なお、巻紙の表面と共有結合された脂肪酸及び/又は脂肪酸エステルの存在の有無は、赤外スペクトルの測定やラマンスペクトルの測定等により検証することができる。
染み低減の観点では、水接触角を高くする(水接触角:90°以上)ことでも有効ではあるが、水接触角を高くするためには、特別な表面処理、例えば、新油性塗工剤を付与する必要がある。本発明の一形態である巻紙の水接触角は特定されないが、特殊な表面処理を行わず、低接触角(90°未満)でも染み低減効果を発現する。
本発明の実施形態にかかる非燃焼加熱型喫煙物品として、例えば図1の構成を有するものを挙げることができる。
図1の非燃焼加熱型喫煙物品10は、充填物11と、充填物11を巻装する第一の巻紙12から構成されるたばこロッド部(「たばこロッド」とも称す)と、該たばこロッド部とは反対側の端部を構成するマウスピース部16とを有し、前記たばこロッド部と前記マウスピース部は、前記充填物を巻装する巻紙と同じ又は別の第二の巻紙13(図1ではチップペーパー)を用いて連結されている。
第一の巻紙及び第二の巻紙の少なくとも一方は、上記で説明した本発明の実施形態にかかる巻紙である。少なくとも第一の巻紙が、本発明の実施形態にかかる巻紙であることが好ましい。また、第一の巻紙12及び第二の巻紙の両方が上記で説明した本発明の実施形態にかかる巻紙であることも好ましい。
図1に示す態様では、マウスピース部16は、紙管部14及びフィルター部15とを備える。また、これらを連結するための第二の巻紙としてチップペーパー13を備える。なお、図1ではマウスピース部16は2つのセグメントから構成されているが、マウスピース部16は単一のセグメントから構成されていてもよく、3つ以上のセグメントから構成されていてもよい。また、マウスピース部を構成するセグメントは、紙管部とフィルター部の両方が含まれるように構成されていてもよいし、どちらかのみから構成されていてもよい。
また、非燃焼加熱型喫煙物品10は、紙管部14と、紙管部14の周囲を覆う第二の巻紙13(チップペーパー)の一部に、外部からの空気を取り入れるための微小孔を有してもよい(図示せず)。そのような微小孔が存在することで、使用時に外部から紙管部14の内部に空気が流入し、前記たばこロッドが加熱されることで生じるエアロゾル生成基材とたばこ香味成分とを含む蒸気が、外部からの空気と接触して温度が低下することで液化し、エアロゾルの生成がより確実になる。
紙管部14は、例えば厚紙を円筒状に加工したものを挙げることができる。
また、フィルター部15の構成について、材料が全体的に密であってもよく、複数のセグメントに分割されたものでもよく、又は、一部に軸方向の空洞を有するチューブ状の構成を有していてもよく、さらに、一部が冷却機能を有する紙管を構成していてもよい。複数のセグメントから構成されている場合、例えば上流側に中空のセグメントを配置し、下流側(使用者の吸口端側)のセグメントとして吸口断面がアセテートトウで充填されている態様を挙げることもできる。このような態様によれば、生成するエアロゾルの無用な損失を防ぐとともに、非燃焼加熱型喫煙物品の外観を良好にすることができる。
また、フィルターの製造において、通気抵抗の調整や添加物(公知の吸着剤や香料、香料保持材等)の添加を適宜設計できる。
また、前期充填物11の充填前の加工方法はさまざまであるが、乾燥したたばこを幅0.8~1.2mmに刻んだものを充填してもよいし、たばこを平均粒径20~200μm程度に粉砕し、ホモジナイズ化したのちに、シート加工したものを幅0.8~1.2mmに刻んだものを充填してもよいし、前記シート加工したものを、刻むことなしにギャザー加工してロッド内に充填してもよい。
上記範囲は、通常のシガレットよりも喫煙温度が低いために、効率的に熱を伝える必要がある非燃焼加熱型喫煙物品に特有の範囲であり、通常のシガレットは、上記範囲の下限を下回るのが一般的である。
上記範囲は、通常のシガレットよりも喫煙温度が低いために、発生する煙の量が少ない非燃焼加熱型喫煙物品に特有の範囲であり、通常のシガレットは、上記範囲の下限を下回るのが一般的である。
上記範囲は、通常のシガレットよりも喫煙温度が低いために、充填物11の量を多くする必要がある非燃焼加熱型喫煙物品に特有の範囲であり、通常のシガレットは、上記範囲の下限を下回るのが一般的である。
電気加熱型喫煙システムの一態様を図2に図示する。電気加熱型喫煙システム30は、電気加熱型デバイス20の内部に配置された、ヒーター24に接する伝熱部材25に、上記で説明した非燃焼加熱型喫煙物品10が接触するように嵌装されて使用される。
電気加熱型デバイス20は、例えば樹脂性の躯体23の内部に、電池ユニット21と制御ユニット22とを有する。
上記のように非燃焼加熱型喫煙物品10は、充填物11と、充填物11を巻装する第一の巻紙12から構成されるたばこロッド部と、該たばこロッド部とは反対側の端部を構成するマウスピース部16とを有し、前記たばこロッド部と前記マウスピース部は、前記充填物11を巻装する巻紙と同じ又は別の第二の巻紙を用いて連結されている。非燃焼加熱型喫煙物品10を電気加熱型デバイスに嵌装すると、該たばこロッドの外周面と、該たばこロッドと紙管部14とを接続する第二の巻紙(チップペーパー13)から構成される外周面の一部が、電気加熱型デバイス20の内部の伝熱部材25と接触する。
電気加熱型デバイス20の内部のヒーター24は、制御ユニット22による制御により発熱する。その熱が伝熱部材25を介して非燃焼加熱型喫煙物品10のたばこロッドに伝わることで、たばこロッドの充填物11に含まれるエアロゾル生成基材と香味成分とが共に揮発する。
ヒーター24による加熱により、前記たばこロッドは概ね150~250℃にまで加熱される。
加熱により生じるエアロゾル生成基材と香味成分を含む蒸気は、前記で説明したメカニズムにより紙管部14の内部でエアロゾル化し、非燃焼加熱型喫煙物品10のフィルター部15を通して使用者の口腔内に到達する。
[実施例1]
パルプ(木材)をショッパーリーグラ法にて69°SRに叩解し、叩解したパルプに、炭酸カルシウム(炭酸Ca)を表1に示す含有量となるように添加した。得られた紙料を用いて、長網式筒型抄紙機により巻紙を調製した。この巻紙を、26.5mm幅×3000mの巻物とし、表1に示す物性を有する実施例1の巻紙を得た。実施例2は26.5mm幅に裁断する前に、カレンダー加工機で高圧処理(処理温度40℃、線圧50kg、速度200m/min、金属コットンを噛ました9段ニップ)を施した。比較例1から5は、表1に示すそれぞれの叩解度、坪量、填料になるように叩解機の電圧、抄紙機のヘッダー高さ、填料比例配合設定を変更することで作製し、実施例1、2と同じく26.5mm幅の巻物を得た。
表1に示す巻紙の物性は、下記に従い評価した。
(坪量)
巻紙の坪量は、JIS P8124に規定される方法により評価した。
(パルプ濾水度)
巻紙の原料のパルプ濾水度は、JIS P8121-1:2012に規定されるショッパーリーグラ法により評価した。
(通気度)
巻紙の通気度は、ISO2965:2009に規定される方法により、CERULEANA社製PPM1000を用いて測定した。
(炭酸Ca)
巻紙の炭酸カルシウム含有量は、坪量と灰分の積により評価した。当該灰分は、JIS P8003に規定される方法により評価した。
(不透明度)
不透明度は、白色度・不透明度測定機(製造者:村上色彩技術研究所、型番:WMS-1)を用いて、ISO2471に準拠して測定した値である。不透明度とは、算出式:単一シート視感反射率係数(R0)/固有視感反射率係数(R∞)×100(%)によって算出された値である。この算出式の固有視感反射率係数(R∞)は、規定の反射率計と光源を用いて有効波長457nm、半値幅44nmとなる分光条件で測定した時の白色度の固有反射率係数である。
上記実施例1、2及び比較例1~5の巻紙を、高速巻き上げ機で巻き上げた。たばこ刻みはあらかじめ香料2g/100g、エアロゾル生成基材(グリセリン)40/100gをタバコ刻みに混合したものを使用した。1本あたりの刻み重量は0.8g、巻円周は24.5mm、巻き長さは68mmとした。巻き上げたたばこロッドは各水準毎に200本ずつプラスチックの密閉容器に入れて保管した。なお、巻き上げた直後のたばこロッドの表面には染みの発生が無いことを確認している。
上記実施例1、2及び比較例1~5を用いて作製した上記ロッドを入れた密閉容器を、温度22℃、相対湿度60%の環境下で、4週間蔵置した後、容器からたばこロッドを取り出し、巻紙表面に発生している染みの数を目視で評価した。当該評価において、染みの最大径(L)が、0.9mm≦L<2.7mmを満たすもの(小さい染み)と、2.7mm≦Lを満たすもの(大きい染み)とを、それぞれ区別して計測を行った。この評価の結果を表1及び図3に示す。なお、大小染みが混在している巻紙については大として数えた。
本評価において、染みの単位とは、他の染みと独立しているか否かに関わらず、楕円(円形を含む)に近似し得る各々の染みである。また、染みの発生程度は200本検査した中での染み発生本数と大小無、各レベルの発生割合%で示した。
