Description

非燃焼加熱型喫煙物品用の巻紙、非燃焼加熱型喫煙物品及び電気加熱型喫煙システムWrapping paper for non-combustion heating type smoking article, non-combustion heating type smoking article and electric heating type smoking system
 本発明は、非燃焼加熱型喫煙物品用の巻紙、非燃焼加熱型喫煙物品及び電気加熱型喫煙システムに関する。 The present invention relates to a wrapping paper for a non-combustion heating type smoking article, a non-combustion heating type smoking article, and an electric heating type smoking system.
 たばこ刻みを含むたばこロッドの周囲から加熱を行い、揮発成分を使用者にデリバリーするタイプの非燃焼加熱型喫煙物品が知られている。非燃焼加熱型喫煙物品では、巻紙で巻装されたたばこロッドが加熱されるが、従来のシガレットとは異なり、使用後(加熱後)もたばこロッドは燃焼せずに残る。
 従来のシガレットでは、たばこ刻みを巻装するための巻紙としては、ロゴなどが付されている場合はあるものの、白色(無色)の紙を用いることが一般的である。
There is known a non-combustion heating type smoking article of a type in which heating is performed from around a cigarette rod including a cigarette cut and a volatile component is delivered to a user. In the non-combustion heating type smoking article, the cigarette rod wound with the wrapping paper is heated, but unlike the conventional cigarette, the cigarette rod remains unburned after use (after heating).
In conventional cigarettes, white (colorless) paper is generally used as a wrapping paper for wrapping cigarettes, although a logo or the like may be attached.
 非燃焼加熱型喫煙物品において、たばこ刻みを巻装する巻紙として従来のシガレットで用いられてきた巻紙を用いると、使用時の加熱によって、使用者にとって不快な変色が生じる場合があることが分かった。
 そこで本発明では、加熱によって発生し得る見た目に関する不快感が生じない、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。
In non-combustion heating type smoking articles, it was found that when using a conventional cigarette wrapping paper as a cigarette wrapping paper, discoloration uncomfortable for the user may occur due to heating during use. .
Accordingly, an object of the present invention is to provide a non-combustion heating type smoking article wrapping paper that does not cause discomfort related to appearance that may be generated by heating.
 上記の課題を解決するために、本発明者は、加熱後に特定範囲の変色域を持つ有色部を有する巻紙を使用することでその不快な変色を目立たなくすることに着目した。
 パルプを主材料とする紙は、一定以上の温度で加熱されれば焦げて茶系に変色するが、原因がパルプや紙の構成成分の熱分解による物理的なものであることから、そういった変色を簡単に防ぐことはできない。しかしながら、焦げによる変色が生じたとしても、元の紙の色とそこからの変色程度が一定範囲で小さければ、不快な焦げ色として視認しにくくすることができることを見出した。
 つまり、加熱前後で色差の小さい領域を持つ紙を使用すれば、上記の不快な変色の問題を解決することができることを見出した。本発明者らはこの視覚的に変色程度の許容される色差変化の領域が数式で表されることを発見し、その数式に、加熱前後のL、a、bの各値を当てはめた場合に特定の数値を示す有色部を有する紙を巻紙として使用することで、非燃焼加熱型喫煙物品に特有の不快な変色に関わる問題を解決できることを見出した。
 本発明の課題は、電気加熱型デバイスにより加熱される非燃焼加熱型喫煙物品に特有のものであり、従来の喫煙物品(シガレット等)では生じなかった課題である。
In order to solve the above problems, the present inventor has paid attention to making the unpleasant discoloration inconspicuous by using a wrapping paper having a colored portion having a specific color change area after heating.
Paper made from pulp is charred and discolored to brown when heated at a temperature above a certain level. However, because the cause is physical due to thermal decomposition of the components of pulp and paper, such discoloration occurs. Cannot be easily prevented. However, it has been found that even if a discoloration due to scoring occurs, if the color of the original paper and the discoloration from the original paper are small within a certain range, it can be difficult to see as an unpleasant scorching color.
That is, it has been found that the above-mentioned problem of unpleasant discoloration can be solved by using paper having a region with a small color difference before and after heating. The inventors of the present invention have found that the area of the color difference that is allowed to be visually discolored is expressed by a mathematical expression, and the values of L * , a * , and b * before and after heating are applied to the mathematical expression. In this case, it has been found that by using a paper having a colored portion showing a specific numerical value as a wrapping paper, problems associated with unpleasant discoloration peculiar to non-combustion heating type smoking articles can be solved.

Further, the non-combustion heating type smoking article 10 may have a microscopic hole for taking in air from the outside in the paper tube portion 14 and a part of the second wrapping paper 13 covering the periphery of the paper tube portion 14. Good (not shown). Due to the presence of such micropores, air flows into the paper tube portion 14 from the outside during use, and the steam containing the aerosol-generating base material and the tobacco flavor component generated by heating the tobacco rod is produced. The liquid is liquefied by contact with the air from the outside and the temperature is lowered, so that the generation of the aerosol becomes more reliable.

<加熱前後の紙サンプルの準備>
 CIELab表色系における明度L、色度a、色度bについて、様々な数値を有する紙を準備した。有色の紙としては、例えばグラビア印刷品、白色の通常パルプに未晒パルプを漉きこんだ混抄品、微細なたばこ葉を漉きこんだたばこシートなどを準備した。全く着色していない紙サンプルとして100%バージンパルプを使用した通常のチップペーパー原紙と巻紙を対照として準備した。全部で26種類の紙を準備した。
 その内容を以下の表1に示す。

<Preparation of paper sample before and after heating>
Papers having various numerical values for lightness L * , chromaticity a * , and chromaticity b * in the CIELab color system were prepared. As the colored paper, for example, a gravure printed product, a mixed product obtained by mixing unbleached pulp with white normal pulp, a tobacco sheet containing fine tobacco leaves, and the like were prepared. As a control, a normal base paper and wrapping paper using 100% virgin pulp as a paper sample that was not colored at all were prepared. A total of 26 types of paper were prepared.
The contents are shown in Table 1 below.
Figure JPOXMLDOC01-appb-T000001
<加熱条件>
 マッフル炉(品名:Muffle Furnace FO410型、ヤマト科学製)をあらかじめ230℃に調整した。扉を開けて紙サンプルを家庭用アルミホイル(材質:アルミニウム箔 厚さ:11μm)に載せ、マッフル炉内に入れて、扉を閉めた。前記動作は素早く行い(3秒以内)、マッフル炉内の温度低下を最小限にした。本実施例での加熱条件(マッフル炉温度設定230℃、紙サンプル加熱時間3分)においては、実際の紙の温度は扉を閉めた後遅くとも1分後にはマッフル炉設定温度と同じ230℃程度であった。これは、色変色温度試験紙(サーモラベル5E-170/サーモラベル5E-210(日油技研工業製)を用いて確認した。
<色差測定>
 加熱前後の各サンプルについて分光光度計(X-Rite社製、品名SpectroEye)を用いて色相を計測した。計測は、光源D65、光源フィルタなし、視野角2°の条件下、ISO白色度92%の紙の上に試料1枚を置き、その上に分光光度計の測定部を押し当てて実施した。
 測定は5か所を繰り返し行い、平均値を解析に使用した。L、a、bは測定をそのまま、ΔL、Δa、Δbは加熱変色後の値から加熱変色前の値を差し引いて求めた。
 色合い評価には様々な評価、分類系があるが CIELab表色系はCIE(国際照明委員会)にて策定された表色系であり、JIS Z 8781-4、 ISO 11664-4の基となっている。人間の感覚に近似し、ごく一般的に使用され、色合いを3次元で数値化できる便利な分類系である。なお、Lは明度、aは青~黄、bは青緑~赤紫を代表する軸であり、Lは値が高いほど明るく、a、bは0に近いほど彩度が落ちる。例えば、L、a、b=100,0,0は白であり、0,0,0は黒である。
<Heating conditions>
A muffle furnace (product name: Muffle Furnace FO410, manufactured by Yamato Kagaku) was adjusted to 230 ° C. in advance. The door was opened and the paper sample was placed on a household aluminum foil (material: aluminum foil thickness: 11 μm), placed in a muffle furnace, and the door was closed. The operation was quick (within 3 seconds) to minimize the temperature drop in the muffle furnace. Under the heating conditions in this example (muffle furnace temperature setting 230 ° C., paper sample heating time 3 minutes), the actual paper temperature is about 230 ° C. which is the same as the muffle furnace setting temperature at least one minute after closing the door. Met. This was confirmed using a color change temperature test paper (Thermo Label 5E-170 / Thermo Label 5E-210 (manufactured by NOF Corporation).
<Color difference measurement>
The hue of each sample before and after heating was measured using a spectrophotometer (product name: SpectroEye, manufactured by X-Rite). The measurement was carried out by placing one sample on a paper with an ISO whiteness of 92% and pressing the measuring part of the spectrophotometer on the paper with a light source D65, no light source filter, and a viewing angle of 2 °.
The measurement was repeated at five locations, and the average value was used for analysis. L * , a * , and b * were measured as they were, and ΔL * , Δa * , and Δb * were obtained by subtracting the value before heat discoloration from the value after heat discoloration.
Although there are various evaluation and classification systems for hue evaluation, the CIELab color system is a color system developed by the CIE (International Commission on Illumination) and is the basis of JIS Z 8781-4 and ISO 11664-4. ing. It is a convenient classification system that approximates the human senses, is very commonly used, and can quantify hues in three dimensions. L * is lightness, a * is blue to yellow, b * is an axis representing blue-green to reddish purple, and L * is brighter as the value is higher, and a * and b * are closer to 0, the saturation Falls. For example, L * , a * , b * = 100, 0, 0 is white and 0, 0, 0 is black.
<官能評価>
 20名のパネル一人一人に加熱前後の紙サンプルを見せ、その色合いから受ける見た目の汚さを問い、パネル20名のうち、汚く見えて不快だと回答した人数が11人以上の場合には、そのサンプルの外観印象を×と判定し、また11人未満の場合は、そのサンプルの外観印象を○と判定し、それらの結果を解析に使用した。
<Sensory evaluation>
Show the paper sample before and after heating to each of the 20 panelists, and ask about the appearance of dirt that is received from the shade. If there are more than 11 panelists who answered that they look dirty and uncomfortable, The appearance impression of the sample was determined as x, and when it was less than 11 people, the appearance impression of the sample was determined as ◯, and the results were used for analysis.
<解析>
 加熱前後のΔL、Δa、Δb値と、外観の印象の優劣に関係性は見られなかった(図3A~3C)。
 色相単体の値の差による単純な図からは加熱後の紙の色合いの良し悪しを推定できないことから、色差データを用いた判別分析を行うことを検討し、複数因子の関連性を知るために判別分析を行った。その結果、以下のような、判別率96.2%と高い確率で外観印象を判定可能なΔL値をパラメータとした関数を得ることができた。判別式のP値は0.001より小さく統計的に高度に有意であり、一般的に判別率は75%を超えれば推定に使えるといわれていることから、判別率が96.2%であることは、ほぼ完全に推定可能なレベルであるという事を意味する。
 判別得点 y=-0.18×ΔL+0.08×Δa+0.13×Δb-2.36 (1)
判別得点0.62以上:×(悪い)
判別得点0.62未満:○(良い)
 式(1)は、加熱後の外観印象は加熱前の紙サンプルと加熱後の紙サンプルの色差であるΔLでほぼ決定づけられることを意味しており、例えば、ΔLが低く、Δa、Δbの値が高くなるほど判別得点が上がる。つまり、その紙の加熱後の印象が悪い方向に位置することになる。
この結果をまとめたのが図4である。

<Analysis>
There was no relationship between ΔL * , Δa * , Δb * values before and after heating and the superiority or inferiority of the appearance impression (FIGS. 3A to 3C).
In order to know the relevance of multiple factors by examining discriminant analysis using color difference data, since it is impossible to estimate the quality of paper after heating from simple figures based on differences in hue values. Discriminant analysis was performed. As a result, it was possible to obtain a function using the ΔL * a * b * value as a parameter that can determine the appearance impression with a high probability of 96.2% as follows. The P value of the discriminant is smaller than 0.001 and is statistically highly significant. Generally, the discriminant rate is 96.2% because it is said that the discriminant rate can be used for estimation if it exceeds 75%. This means that the level is almost completely predictable.
Discrimination score y = −0.18 × ΔL * + 0.08 × Δa * + 0.13 × Δb * −2.36 (1)
Discrimination score of 0.62 or more: x (bad)
Discrimination score less than 0.62: ○ (good)
Equation (1) means that the appearance impression after heating is almost determined by ΔL * a * b * , which is the color difference between the paper sample before heating and the paper sample after heating. For example, ΔL * is low. , Δa * , Δb * increases as the discrimination score increases. That is, the impression after the paper is heated is positioned in a bad direction.
The results are summarized in FIG.
The discriminant analysis was performed under the following conditions using Bell Curve's Excel Statistics Ver. 2.15 multivariate analysis discriminant analysis group 2.
(1) Increase / decrease method P value: input 0.2 removal 0.2
(2) Analyzing excluding variables that are linearly combined
 図5は、更に詳しく説明するために、今回調査した紙サンプルのΔaとΔbの関係を表したものである。
 3次元的に明示することができないため、ΔLの値については便宜的に-10で二値化し、-10よりも値が低い(暗く変色)ものについて、黒丸または太字の×で表した。
FIG. 5 shows the relationship between Δa * and Δb * of the paper sample investigated this time for more detailed explanation.
Since it is not possible to specify three-dimensionally, the value of ΔL * is binarized by −10 for convenience, and the value lower than −10 (darkly discolored) is represented by a black circle or bold x.
 評価で外観印象が悪かったものは「×」で表しており、Δa、Δbの値が共に高い所に位置している。これは加熱により、赤紫や黄色、あるいはそれらが合わさった茶色方向への変色が大きいことを意味しており、また相対的にΔLも低いものが多く見られる。つまり、これらのサンプルは、視覚的にはいわゆる薄い焦げ色から濃い焦げ色に近づくサンプル群であり、直感的にも外観印象が悪い群であることが理解できる。
 これらサンプル群は加熱前はL値が比較的高く、またa値、b値も低い、つまり明るく彩度の低いものが多い。こういった明るく薄い色相のサンプルは加熱による茶色の変化が目立ちやすく外観印象の悪さに結びつく。
 反対に外観印象が良かった「○」のサンプルについては、Δa、Δbの値が共に低い所に位置している。これは加熱により、青や緑色、あるいはそれらが合わさった青緑の方向への変色が大きいことを意味している。中には相対的にΔL値が低い、即ち明度が小さく暗いにもかかわらず○のものも見られる。これらのサンプル群は、×の場合とは反対に、加熱前は比較的L値が低く、またa値とb値も高い、つまり暗めの彩度の高いものが多い。こういった濃いめの色相のサンプルは加熱による変化が目立ちにくいため、外観印象の良さに結びつくと考えられる。
 プロットを全体的に見ると、Δaは±20、Δbは±30と幅広い範囲にプロットが分布していることから、この実験が部分的ではなく、様々な色相の変化をするサンプルを網羅していることが分かる。
Those having a poor appearance impression in the evaluation are represented by “x”, and both Δa * and Δb * are high. This means that reddish purple or yellow, or the color change in the brown direction in which they are combined, is large due to heating, and many ΔL * are relatively low. That is, it can be understood that these samples are a group of samples that visually approach a so-called light burnt color to a deep burnt color, and are intuitively a group with a poor appearance impression.
Many of these sample groups have a relatively high L * value before heating and a low a * value and b * value, that is, they are bright and have low saturation. Such bright and thin hue samples are prone to browning due to heating, leading to poor appearance.
On the other hand, the sample “◯” whose appearance impression was good is located where both the values of Δa * and Δb * are low. This means that the discoloration in the direction of blue or green, or the blue-green combined with them, is large due to heating. Some of them have relatively low ΔL * values, that is, ◯ although the brightness is small and dark. Contrary to the case of x, these sample groups have a relatively low L * value before heating and a high a * value and b * value, that is, many samples with dark saturation. These darker hue samples are less likely to change due to heating, which is thought to lead to better appearance.
Overall, the plot is distributed over a wide range of Δa * is ± 20 and Δb * is ± 30, so this experiment is not partial and covers samples with various hue changes. You can see that
 本発明では、紙の加熱前後の色の変化程度に着目し、その領域を数値として把握することで有効な範囲を規定した。
 本来、こういったパラメータ化には単純に加熱前の色相で領域を規定するのが考えやすいと想像されるが、今回の統計的手法では、色差ではない加熱前の紙のL、a、bの値のみから有用な数式は得られなかった。それは、色に含まれる顔料や、染料、等の有色成分はそれぞれ異なる熱分解挙動を持つために、加熱後の変色程度も色成分ごとに異なるためと考えられる。従って、元の紙の色のみではなく、変色程度で正確に外観印象を推定できる本発明の考え方は合理的である。
In the present invention, paying attention to the degree of color change before and after heating the paper, the effective range is defined by grasping the area as a numerical value.
Originally, it is conceivable that it is easy to simply define the area by the hue before heating for such parameterization, but in this statistical method, L * and a * of the paper before heating which are not color differences are considered . , B * alone was not useful. This is presumably because the color components such as pigments and dyes contained in the colors have different thermal decomposition behaviors, and thus the degree of discoloration after heating differs for each color component. Therefore, the idea of the present invention that can accurately estimate the appearance impression not only with the original paper color but with the degree of color change is reasonable.
