Description

紙を含むたばこセグメントTobacco segment including paper
　本発明は、充填物として紙を含むたばこセグメントに関する。 The present invention relates to tobacco segments containing paper as filler.
　非燃焼加熱型香味吸引物品は、たばこ材料が充填されたたばこセグメントを備え、これが加熱されることによって香喫味を発生する。これまで、タバコ材料を含む第１のシートと、非タバコ香味料を含む第２のシートを備えるたばこ材料を充填した非燃焼加熱型香味吸引物品（特許文献１）、捲縮加工を施した紙を含むたばこ材料を充填した非燃焼加熱型香味吸引物品（特許文献２）、セルロース充填剤を含む喫煙物品（特許文献３）等が提案されている。 A non-combustion heating type flavor inhalation article comprises a tobacco segment filled with tobacco material, which is heated to generate a flavor. Until now, a tobacco material-filled non-combustion heated flavor inhalation article comprising a first sheet containing a tobacco material and a second sheet containing a non-tobacco flavoring material (Patent Document 1), crimped paper (Patent Document 2), a smoking article containing a cellulose filler (Patent Document 3), and the like have been proposed.
特表２０１５－５１７８１８号公報Japanese Patent Publication No. 2015-517818 特許６６８３６９８号Patent No. 6683698 米国特許出願２０２０／０３５９６７４号明細書US patent application 2020/0359674
　非燃焼加熱型香味吸引物品において、香喫味を容易に調整できればユーザーの様々な嗜好に対応することができる。従来の燃焼型たばこではフィルターや吸い口側に設けられた穿孔から空気を導入することで香喫味を希釈してきた。しかし、たばこ含有セグメントを比較的低温に加熱してエアロゾルを発生させる非燃焼加熱型香味吸引物品では、フィルターや吸い口側に設けられた穿孔から空気を導入すると、エアロゾルが再凝集してしまうので十分なデリバリーを達成できないという問題がある。また、前記特許文献に記載の方法によっても香喫味を調整できるがいまだ改善の余地があった。したがって、非燃焼加熱型香味吸引物品において香喫味を調整するために新規な手段が必要となる。かかる事情に鑑み、本発明は、希釈された香喫味を呈する非燃焼加熱型香味吸引物品を提供することを課題とする。 In the non-combustion heating type flavor sucking article, if the flavor and taste can be easily adjusted, it will be possible to respond to various tastes of users. In conventional combustible cigarettes, the flavor and taste have been diluted by introducing air through a filter or perforations provided on the mouthpiece side. However, in non-combustion heating type flavor inhalation articles that generate aerosol by heating the tobacco-containing segment to a relatively low temperature, if air is introduced through the filter or perforations provided on the mouthpiece side, the aerosol will reaggregate. There is a problem that sufficient delivery cannot be achieved. Moreover, the method described in the above-mentioned patent document can also adjust the flavor and taste, but there is still room for improvement. Therefore, new means are needed to adjust the flavor and taste in non-combustion heating flavor inhalation articles. In view of such circumstances, an object of the present invention is to provide a non-combustion heating type flavor inhaling article exhibiting a diluted flavor.

For example, the length of the tobacco segment 20A is 20 mm, the length of the cooling section 20B is 20 mm, and the length of the filter section 20C is 7 mm. The length of each of these members can be changed as appropriate according to manufacturability, required quality, and the like. Although FIG. 2 shows a mode in which the first segment 25 is arranged, only the second segment 26 may be arranged on the downstream side of the cooling section 20B without arranging this.
　１）たばこセグメント２０Ａ
　たばこセグメント２０Ａ中のたばこ充填物２１は、前記たばこ材料と紙を含む。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。たばこおよび紙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。また、ラッパー２２として、前記紙を用いることもできる。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、エアロゾル生成基材および水が気化し、吸引に供される。 1) Tobacco segment 20A
Tobacco filler 21 in tobacco segment 20A includes the tobacco material and paper. The method of filling the tobacco filling 21 in the wrapper 22 is not particularly limited, but for example, the tobacco filling 21 may be wrapped in the wrapper 22 or the tobacco filling 21 may be filled in the cylindrical wrapper 22 . If the tobacco and paper have a longitudinal direction, such as a rectangular shape, they may be packed in unspecified directions within the wrapper 22, aligned or aligned with the axial direction of the tobacco segment 20A. The filling may be aligned in a direction orthogonal to this. As the wrapper 22, the paper can also be used. By heating the tobacco segment 20A, the tobacco components, aerosol-generating base material and water contained in the tobacco filling 21 are vaporized and provided for inhalation.
　２）冷却部２０Ｂ
　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２１Ａ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。 2) Cooling section 20B
It is preferable that the cooling part 20B is configured by a cylindrical member. The tubular member may be, for example, a paper tube 23 formed by processing cardboard into a cylindrical shape. Cooling section 20B may also be formed by a thin sheet of material that is crumpled and then pleated, gathered, or folded to form channels. As such a material, for example, a sheet material selected from the group consisting of polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate, polylactic acid, cellulose acetate, and aluminum foil can be used. The total surface area of the cooling part 20B is appropriately prepared in consideration of the cooling efficiency, and can be, for example, 300 to 1000 mm 2 /mm. Cooling section 20B is preferably provided with perforations 24 . Due to the presence of the perforations 24, outside air is introduced into the cooling section 20B during suction. As a result, the vaporized aerosol component generated by the heating of the tobacco segment 21A comes into contact with the outside air, and its temperature is lowered, so that it is liquefied and an aerosol is formed. The diameter (spanning length) of the perforations 24 is not particularly limited, but may be, for example, 0.5 to 1.5 mm. The number of perforations 24 is not particularly limited, and may be one or two or more. For example, a plurality of perforations 24 may be provided on the circumference of the cooling section 20B.
　冷却部２０Ｂは、その軸方向の長さが例えば７～２８ｍｍのロッド形状とすることができる。例えば、冷却部２０Ｂの軸方向の長さは１８ｍｍとすることができる。冷却部２０Ｂは、その軸方向断面形状として実質的に円形であり、直径を５～１０ｍｍとすることができる。例えば、冷却部の直径は、約７ｍｍとすることができる。 The cooling part 20B can be rod-shaped with an axial length of, for example, 7 to 28 mm. For example, the axial length of the cooling part 20B can be 18 mm. The cooling portion 20B has a substantially circular axial cross-sectional shape, and can have a diameter of 5 to 10 mm. For example, the diameter of the cooling section can be approximately 7 mm.
　３）フィルター部２０Ｃ
　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。 3) Filter section 20C
Although the configuration of the filter part 20C is not particularly limited, it may be composed of a single or a plurality of filling layers. The outer side of the packing layer may be wrapped with one or more wrapping papers. The ventilation resistance of the filter portion 20C can be appropriately changed depending on the amount, material, etc. of the filter filler filled in the filter portion 20C. For example, when the filter filling material is cellulose acetate fiber, the ventilation resistance can be increased by increasing the amount of cellulose acetate fiber with which the filter portion 20C is filled. When the filter packing is cellulose acetate fibers, the packing density of the cellulose acetate fibers can be from 0.13 to 0.18 g/cm 3 . The airflow resistance is a value measured by an airflow resistance measuring instrument (trade name: SODIMAX, manufactured by SODIM).
　フィルター部２０Ｃの周の長さは特に限定されないが、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。フィルター部２０Ｃの軸方向（図２の水平方向）の長さは４～１０ｍｍで選択可能であり、その通気抵抗が１５～６０ｍｍＨ２Ｏ／ｓｅｇとなるように選択される。フィルター部２０Ｃの軸方向の長さは５～９ｍｍが好ましく、６～８ｍｍがより好ましい。フィルター部２０Ｃの断面の形状は特に限定されないが、例えば円形、楕円形、多角形等であることができる。またフィルター部２０Ｃには香料を含んだ破壊性カプセル、香料ビーズ、香料を直接添加していてもよい。 Although the length of the circumference of the filter portion 20C is not particularly limited, it is preferably 16 to 25 mm, more preferably 20 to 24 mm, even more preferably 21 to 23 mm. The length in the axial direction (horizontal direction in FIG. 2) of the filter portion 20C can be selected from 4 to 10 mm, and is selected so that the ventilation resistance is 15 to 60 mmH 2 O/seg. The axial length of the filter portion 20C is preferably 5 to 9 mm, more preferably 6 to 8 mm. The shape of the cross section of the filter portion 20C is not particularly limited, and may be, for example, circular, elliptical, polygonal, or the like. In addition, destructible capsules containing perfume, perfume beads, and perfume may be directly added to the filter portion 20C.
　フィルター部２０Ｃは第１セグメント２５としてセンターホール部を備えていてもよい。センターホール部は１つまたは複数の中空部を有する第１充填層２５ａと、当該充填層を覆うインナープラグラッパー（内側巻紙）２５ｂとで構成される。センターホール部は、マウスピース部の強度を高める機能を有する。センターホール部はインナープラグラッパー２５ｂを持たず、熱成型によってその形が保たれていてもよい。フィルター部２０Ｃは第２セグメント２６を備えていてもよい。第２セグメント２６は第２充填層２６ａと当該充填層を覆うインナープラグラッパー（内側巻紙）２６ｂとで構成される。第２充填層２６ａは、例えば酢酸セルロース繊維が高密度で充填されトリアセチンを含む可塑剤が酢酸セルロース重量に対して、６～２０重量％添加されて硬化された内径φ５．０～φ１．０ｍｍのロッドとすることができる。第２充填層は繊維の充填密度が高いため、吸引時は、空気やエアロゾルは中空部のみを流れることになり、第２充填層内はほとんど流れない。センターホール部内部の第二の充填層が繊維充填層であることから、使用時の外側からの触り心地は、使用者に違和感を生じさせることが少ない。 The filter part 20C may have a center hole part as the first segment 25. The center hole portion is composed of a first filling layer 25a having one or more hollow portions and an inner plug wrapper (inner wrapping paper) 25b covering the filling layer. The center hole portion has a function of increasing the strength of the mouthpiece portion. The center hole portion does not have the inner plug wrapper 25b, and the shape may be maintained by thermoforming. The filter portion 20C may have a second segment 26 . The second segment 26 is composed of a second filling layer 26a and an inner plug wrapper (inner wrapping paper) 26b covering the filling layer. The second filling layer 26a has an inner diameter of φ5.0 to φ1.0 mm, for example, filled with cellulose acetate fibers at a high density and hardened by adding 6 to 20% by weight of a plasticizer containing triacetin to the weight of the cellulose acetate. It can be a rod. Since the second packed layer has a high packing density of fibers, air and aerosol flow only in the hollow portion during suction, and hardly flow in the second packed layer. Since the second filling layer inside the center hole portion is a fiber filling layer, the feeling of touch from the outside during use does not make the user feel uncomfortable.
　第１充填層２５ａと第２充填層２６ａとはアウタープラグラッパー（外側巻紙）２７で接続されている。アウタープラグラッパー２７は、例えば円筒状の紙であることができる。また、たばこセグメント２０Ａと、冷却部２０Ｂと、接続済みの第１充填層２５ａと第２充填層２６ａとは、マウスピースライニングペーパー２８により接続されている。これらの接続は、例えばマウスピースライニングペーパー２８の内側面に酢酸ビニル系糊等の糊を塗り、前記３つの部材を巻くことで接続することができる。これらの部材は複数のライニングペーパーで複数回に分けて接続されていてもよい。 The first filling layer 25a and the second filling layer 26a are connected by an outer plug wrapper (outer wrapping paper) 27. The outer plug wrapper 27 can be, for example, a cylinder of paper. Further, the tobacco segment 20A, the cooling section 20B, and the connected first and second filling layers 25a and 26a are connected by a mouthpiece lining paper 28. As shown in FIG. These connections can be made, for example, by applying paste such as vinyl acetate paste to the inner surface of the mouthpiece lining paper 28 and winding the three members. These members may be connected in a plurality of times with a plurality of lining papers.
　非燃焼加熱型たばこ香味吸引物品とエアロゾルを発生させるための加熱デバイスとの組合せを、特に非燃焼加熱型たばこ香味吸引システムともいう。当該システムの一例を図２に示す。図中、非燃焼加熱型たばこ香味吸引システムは、非燃焼加熱型たばこ香味吸引物品２０と、たばこセグメント２０Ａを外側から加熱する加熱デバイス１０とを備える。 A combination of a non-combustion heating tobacco flavor inhalation article and a heating device for generating an aerosol is also called a non-combustion heating tobacco flavor inhalation system. An example of such a system is shown in FIG. In the figure, the non-combustion heating tobacco flavor inhalation system comprises a non-combustion heating tobacco flavor inhalation article 20 and a heating device 10 for externally heating tobacco segments 20A.
　加熱デバイス１０は、ボディ１１と、ヒーター１２と、金属管１３と、電池ユニット１４と、制御ユニット１５とを備える。ボディ１１は筒状の凹部１６を有し、これに挿入されるたばこセグメント２０Ａと対応する位置に、ヒーター１２と金属管１３が配置されている。ヒーター１３は電気抵抗によるヒーターであることができ、温度制御を行う制御ユニット１５からの指示により電池ユニット１４より電力が供給され、ヒーター１２の加熱が行われる。ヒーター１２から発せられた熱は、熱伝導度の高い金属管１３を通じてたばこセグメント２０Ａへ伝えられる。当該図には、加熱デバイス１０はたばこセグメント２０Ａを外側から加熱する態様を示したが、内側から加熱するものであってもよい。加熱デバイス１０による加熱温度は特に限定されないが、４００℃以下であることが好ましく、１５０～４００℃であることがより好ましく、２００～３５０℃であることがさらに好ましい。加熱温度とは加熱デバイス１０のヒーターの温度を示す。 The heating device 10 includes a body 11, a heater 12, a metal tube 13, a battery unit 14, and a control unit 15. The body 11 has a cylindrical recess 16, and the heater 12 and the metal tube 13 are arranged at positions corresponding to the tobacco segments 20A inserted therein. The heater 13 can be a heater based on electric resistance, and electric power is supplied from the battery unit 14 according to an instruction from the control unit 15 for temperature control, and the heater 12 is heated. Heat emitted from the heater 12 is transmitted to the tobacco segment 20A through the metal pipe 13 having high thermal conductivity. Although the drawing shows that the heating device 10 heats the tobacco segment 20A from the outside, the heating device 10 may heat the tobacco segment 20A from the inside. The heating temperature of the heating device 10 is not particularly limited, but is preferably 400°C or less, more preferably 150 to 400°C, and even more preferably 200 to 350°C. A heating temperature indicates the temperature of the heater of the heating device 10 .
