Description

非燃焼型喫煙物品用シートおよび非燃焼型喫煙物品、並びにそれらの製造方法Non-combustion-type smoking article sheet, non-combustion-type smoking article, and production method thereof
　本発明は、非燃焼型喫煙物品用シートおよびこのシートを含む非燃焼型喫煙物品、並びにそれらの製造方法に関する。 The present invention relates to a sheet for non-combustion-type smoking articles, a non-combustion-type smoking article including the sheet, and a method for producing the same.
　シガレットは、タバコを燃焼させることによりヒトの味覚、嗅覚を通じて煙（エアロゾル）中の香喫味を味わう喫煙物品の代表的なものである。 Cigarette is a typical smoking article that tastes the savory taste of smoke (aerosol) through the taste and smell of humans by burning tobacco.
　近年、シガレットに代わり、タバコを燃焼させることなく、香味を味わう非燃焼型喫煙物品が開発されている（例えば、特許文献１、特許文献２、特許文献３参照）。従来の非燃焼型喫煙物品は、先端に取付けた発熱部材である熱源部と、適当な基材に香味成分を保持させた香味発生材を含む香味発生部を備え、熱源部と香味発生部とは物理的に分離されている。つまり、非燃焼型喫煙物品の製造においては、熱源部と香味発生部とをそれぞれ別々に作製する工程を要するのが現状である。熱源としてはもっぱら炭素質熱源が使用され、これは炭素粒子とバインダを含む炭素質材料の押し出し円柱状中実成形品である。この炭素質熱源には、空気通路として機能し、熱源の初期の燃焼をしやすくさせ、かつ熱源を通過して暖められた空気が香味発生部に流入するように貫通孔が設けられている。しかし、上記熱源は、空気通路以外は中実の物品であり、通常のシガレットに比べて着火させることが困難である。また、押し出し中実成形品からなる熱源を備えた非燃焼型喫煙物品は、１本喫煙する際に、パフ毎の香味成分量について最大値と最小値との差が大きく、特に初めの２～３パフにおける香味成分量が少なく、１本につき平均して一定の香味を味わえない。 In recent years, instead of cigarettes, non-combustion smoking articles that taste flavor without burning tobacco have been developed (see, for example, Patent Document 1, Patent Document 2, and Patent Document 3). A conventional non-combustion type smoking article includes a heat source part that is a heat generating member attached to the tip, and a flavor generating part that includes a flavor generating material in which a flavor component is held on a suitable base material, the heat source part and the flavor generating part, Are physically separated. That is, in the manufacture of non-combustion smoking articles, the current situation is that a process for separately producing the heat source part and the flavor generating part is required. A carbonaceous heat source is exclusively used as the heat source, which is an extruded cylindrical solid molded product of a carbonaceous material containing carbon particles and a binder. This carbonaceous heat source is provided with a through-hole that functions as an air passage, facilitates initial combustion of the heat source, and allows air warmed through the heat source to flow into the flavor generating portion. However, the heat source is a solid article other than the air passage, and is difficult to ignite as compared with a normal cigarette. In addition, a non-combustible smoking article having a heat source made of a solid extruded product has a large difference between the maximum value and the minimum value for the amount of flavor component for each puff when smoking one, especially the first 2 to 2 The amount of flavor component in 3 puffs is small, and it is not possible to taste a certain flavor on average per one.

A second object of the present invention is to provide a non-combustion smoking article that can ignite a heat source relatively easily and that can taste an almost constant flavor on an average.

As shown, it was folded and inserted to produce a smoking article of the present invention (Example 1).
　また、実施例１で用いた炭素質熱源混合物と同じ組成の混合物を中実円柱状に押し出し成形し、空気の流路となる軸方向の溝を外周面内に設けて加熱源を作製した。この加熱源を図４の非燃焼型喫煙物品の加熱源３４と入れ替えて、比較例１の喫煙物品を作製した。 Also, a mixture having the same composition as the carbonaceous heat source mixture used in Example 1 was extruded into a solid cylindrical shape, and an axial groove serving as an air flow path was provided in the outer peripheral surface to produce a heating source. This heating source was replaced with the heating source 34 of the non-combustion type smoking article of FIG.
　比較例２の喫煙物品として、上記した通り、図４に示す市販されていた非燃焼型喫煙物品（商品名：エアーズ）を用いた。 As described above, as the smoking article of Comparative Example 2, a commercially available non-combustion smoking article (trade name: Ayers) shown in FIG. 4 was used.
　以上の作製した実施例１の喫煙物品試料と、比較例１および比較例２の喫煙物品を、カナダ強制喫煙条件（喫煙容量５５ｍＬ／２秒；吸煙間隔３０秒；ベントブロック１００％）の下で吸煙させた。着火に際し、比較例１の喫煙物品および比較例２の喫煙物品は、日本たばこ協会（ＴＩＯＪ）法に準拠して電気式ライターで３０秒間加熱しなければならなかったのに対し、実施例１の喫煙物品試料は通常のシガレットと同様に２秒で着火することができた。 The prepared smoking article sample of Example 1 and the smoking articles of Comparative Example 1 and Comparative Example 2 were subjected to Canadian forced smoking conditions (smoking capacity 55 mL / 2 seconds; smoke absorption interval 30 seconds; vent block 100%). Smoke it. On ignition, the smoking article of Comparative Example 1 and the smoking article of Comparative Example 2 had to be heated with an electric lighter for 30 seconds in accordance with the Japan Tobacco Association (TIOJ) law, whereas The smoking article sample could be ignited in 2 seconds like a normal cigarette.
　また、本発明の喫煙物品試料、比較例１および２の喫煙物品をそれぞれ７パフまで自動喫煙機により吸煙させた。パフ毎に煙を捕集し、総粒子状物質（ＴＰＭ）の量を測定した。結果を下記表１に示す。
Figure JPOXMLDOC01-appb-T000001
 Moreover, the smoking article sample of the present invention and the smoking articles of Comparative Examples 1 and 2 were each smoked up to 7 puffs by an automatic smoking machine. Smoke was collected for each puff and the amount of total particulate matter (TPM) was measured. The results are shown in Table 1 below.
Figure JPOXMLDOC01-appb-T000001
　表１に示す結果から、本発明の喫煙物品は、押し出し成形品からなる加熱源を用いた比較例１の喫煙物品に比べ、喫煙初期（３パフ目まで）のＴＰＭ量が改善されていることが確認された。特に、押し出し成形品からなる加熱源を用いた比較例１および２の喫煙物品では、中間のパフ（５パフ目近傍～６パフ目）でＴＰＭ量が著しく増大し、高い極大値を有するプロファイルを示す。これに対し、本発明の喫煙物品である実施例１の喫煙物品は、パフ毎のＴＰＭ量の変化幅が小さく、パフ毎のＴＰＭ量についての極大値と極小値の階差が低減しており、１本につき平均してほぼ一定の喫味を味わうことができることがわかる。また、実施例１の本発明の喫煙物品は、比較例２の従来の喫煙物品に比べ、喫煙初期のＴＭＰ量が改善されていることが確認された。 From the results shown in Table 1, the smoking article of the present invention has an improved amount of TPM at the beginning of smoking (up to the third puff) compared to the smoking article of Comparative Example 1 using a heating source made of an extruded product. Was confirmed. In particular, in the smoking articles of Comparative Examples 1 and 2 using a heat source made of an extruded product, the amount of TPM remarkably increased in the middle puff (near the fifth puff to the sixth puff), and a profile having a high maximum value was obtained. Show. On the other hand, the smoking article of Example 1 which is the smoking article of the present invention has a small change width of the TPM amount for each puff, and the difference between the maximum value and the minimum value for the TPM amount for each puff is reduced. It turns out that it can taste a substantially constant taste per one on average. Moreover, it was confirmed that the amount of TMP in the early stage of smoking was improved in the smoking article of Example 1 of the present invention compared to the conventional smoking article in Comparative Example 2.
