Definitions
- the present invention relates to a non-combustion heating tobacco coolant, a non-combustion heating tobacco product, and an electrically heated tobacco product.
- Non-combustion heating tobacco that is used by inserting it into an electric heating device has been developed (Patent Document 1).
- the non-combustion heated tobacco is generally composed of a tobacco rod portion in which a composition containing flavor components such as shredded tobacco, an aerosol base material, etc. is wrapped with wrapping paper, and components generated from the tobacco rod portion by heating are sucked. It is equipped with a mouthpiece part for playing and a tip paper for wrapping them.
- the non-combustion heating tobacco is inserted or placed in the electric heating device.
- a heat source provided in the electrically heated device heats at least a portion of the tobacco rod without burning it, thereby generating volatile substances from the composition contained in the tobacco rod. These volatile substances are carried from the tobacco rod side to the mouthpiece side by the user's inhalation, and are cooled in the cooling segment included in the mouthpiece to form an aerosol.
- Patent Document 1 discloses an aerosol cooling element comprising a plurality of longitudinally extending channels and having a porosity of between 50% and 90% in the longitudinal direction.
- the temperature of smoke generated in a cigarette can reach 800° C. or higher. At such a high temperature, the amount of moisture contained in the smoke becomes very small, so the user tends to have difficulty in perceiving the high temperature.
- the aerosol generated by non-combustion heating tobacco contains a relatively large amount of water. Therefore, although the temperature of the aerosol is lower than that of the cigarette, the temperature of the aerosol is easier for the user to perceive than that of the cigarette.
- the method of lowering the temperature of the aerosol includes: efficient and safe cooling; stable from the manufacturing stage of the non-combustion-heated cigarette to the end of use by the user; However, it is difficult to satisfy all these characteristics with conventional methods, and there is room for improvement.
- the present invention provides non-combustion heating that is excellent in efficiency, safety, and stability, does not adversely affect the flavor of the aerosol, and can reduce the temperature of the aerosol while suppressing the production cost. It is an object of the present invention to provide a coolant for tobacco, a non-combustion heated tobacco having the same, and an electrically heated tobacco product.
- the present inventors have found that the above problems can be solved by using a granular base material impregnated with a polyhydric alcohol, and have arrived at the present invention. That is, the gist of the present invention is as follows.
- the porous granular substrate is one or more selected from the group consisting of charcoal, calcium carbonate, cellulose, acetate, sugar, starch, and chitin. Coolant for combustion-heated cigarettes.
- a non-combustion heating tobacco having a mouthpiece member containing the coolant for non-combustion heating tobacco according to any one of [1] to [6].
- an electric heating device comprising a heater member, a battery unit serving as a power source for the heater member, and a control unit for controlling the heater member;
- An electrically heated tobacco product comprising: the non-combustion heated tobacco of [7] or [8].
- a non-combustion heated tobacco coolant, a non-combustion heated tobacco having the same, and an electrically heated tobacco product can be provided.

- 1 is a schematic diagram of a system for evaluating a cooling effect in Examples.
- FIG. 4 is a graph showing evaluation results of cooling effects in Examples.
- a coolant for non-combustion heated cigarettes comprises a polyhydric alcohol and a porous granular substrate, and the granular substrate is impregnated with the polyhydric alcohol. It is a coolant for combustion-heated cigarettes (hereinafter also simply referred to as "coolant").
- the polyhydric alcohol contained in the above coolant is a material often used as a coolant for brine refrigerators used in the food industry.
- the reason why the polyhydric alcohol is used is that it can be efficiently cooled, is a substance with extremely low toxicity, and is excellent in safety.
- polyhydric alcohols have a low melting point and can normally maintain a stable state as a liquid within the heating temperature range for use of non-combustion-heating cigarettes, they can be used from the manufacturing stage of non-combustion-heating cigarettes to the completion of use by the user. It remains stable until
- polyhydric alcohols have been conventionally used as moisturizing agents for non-combustion heating cigarettes, do not adversely affect flavor, and are not particularly expensive materials.
- the hardness tends to be insufficient, but in many cases.
- a hydric alcohol in the granular base material, this problem of hardness can be improved, and in turn, the holding feeling of handling during smoking can be improved.
- a polyhydric alcohol in the granular base material, it is possible to use the granule handling method and equipment such as granular activated carbon that have been cultivated in the development of conventional non-combustion heating tobacco as they are. As a result, the manufacturing cost can be suppressed.
- the conventional method of lowering the heating temperature at the time of use has a problem that the generation of aerosol is likely to become unstable, and the conventional method of introducing vent air has a problem of diluting the smoking taste. was occurring.
- the above-described method using a coolant does not cause such a problem, so from this point of view as well, the above-described method using a coolant is excellent in cooling efficiency and stability.
- the conventional method of lengthening the aerosol flow path increases the manufacturing cost of the non-combustion-heating cigarette itself, and is likely to limit the freedom of design of the non-combustion-heating cigarette. Since the method using the coolant does not cause such problems, from this point of view as well, the method using the coolant can suppress the manufacturing cost.

また、前記A工程は、前記多孔質の顆粒状基材を流動させながら、該流動する多孔質の顆粒状基材に前記溶液を噴霧又は滴下して顆粒を得る工程であることが好ましい。多孔質の顆粒状基材を前記溶液に浸漬し、その後脱液する工程により得られる冷却剤には、粒径の大きな塊が含まれる虞があるところ、該工程により得られる冷却剤は、粒径の大きな塊を生じることなく、平均粒子径が上記範囲内である冷却剤を得られやすい。

本発明の別の実施形態は、上記の非燃焼加熱式たばこ用冷却剤が含まれるマウスピース部を有する、非燃焼加熱式たばこである。
実施形態に係る非燃焼加熱式たばこの一例を図1に示す。以下、該図1を参照しながら非燃焼加熱式たばこの説明を行う。
本実施形態で設けてもよい開孔Vは、冷却セグメント12とフィルターセグメント13との境界から、冷却セグメント側の方向の4mm以上の領域に存在する態様を挙げることができる。該構成とすることにより、加熱により生成される成分や空気の温度を下げる冷却能力を向上させることができ、さらには、冷却セグメント内での該成分や空気の滞留を抑制し、ひいては成分のデリバリー量を向上させることができる。
なお、加熱により生成される成分としては、例えば、香料由来の香味成分や、たばこ葉由来のニコチンやタール、エアロゾル基材由来のエアロゾル成分が挙げられる。
アスペクト比=h/w
wは柱状体の底面の幅(本明細書においては、たばこロッド部側の底面の幅とする。)、hは高さであり、h≧wであることが好ましい。本明細書においては、長軸方向はhで示された方向であると規定する。したがって、仮にw≧hである場合においてもhで示された方向を便宜上長軸方向と称する。底面の形状は限定されず、多角、角丸多角、円、または楕円等であってよく、幅wは当該底面が円形の場合は直径、楕円形である場合は長径、または多角形もしくは角丸多角である場合は外接円の直径もしくは外接楕円の長径である。
非燃焼加熱式たばこ10の長軸方向の長さhは、特段制限されず、例えば、通常40mm以上であり、45mm以上であることが好ましく、50mm以上であることがより好ましい。また、通常100mm以下であり、90mm以下であることが好ましく、80mm以下であることがより好ましい。
非燃焼加熱式たばこ10の柱状体の底面の幅wは、特段制限されず、例えば、通常5mm以上であり、5.5mm以上であることが好ましい。また、通常10mm以下であり、9mm以下であることが好ましく、8mm以下であることがより好ましい。
通気抵抗は、ISO標準法(ISO6565:2015)に従って、例えばセルリアン社製フィルター通気抵抗測定器を使用して測定される。通気抵抗は、非燃焼加熱式たばこ10の側面における空気の透過が行なわれない状態で一方の端面(第1端面)から他方の端面(第2端面)に所定の空気流量(17.5cc/min)の空気を流した際の、第1端面と第2端面との気圧差を指す。単位は、一般的にはmmH2Oで表す。通気抵抗と非燃焼加熱式たばこの長さとの関係は、通常実施する長さ範囲(長さ5mm~200mm)においては比例関係であることが知られていて、長さが倍になれば、非燃焼加熱式たばこの通気抵抗は倍になる。
マウスピース部14の構成は、フィルター濾材を含むフィルターセグメント13を含んでいれば特段制限されず、フィルターセグメント13のみから構成されていてよく、また、冷却セグメント12と、フィルター濾材を含むフィルターセグメント13とを含み、非燃焼加熱式たばこ10の軸方向に対して、冷却セグメント12が、たばこロッド部11とフィルターセグメント13とに隣接して挟持されるように構成されていてもよい。マウスピース部14がフィルターセグメント13のみから構成される場合、上記の冷却剤は、フィルターセグメント13に含まれるが、マウスピース部14がフィルターセグメント13及び冷却セグメント12から構成される場合、上記の冷却剤は、フィルターセグメント13及び冷却セグメント12の少なくともいずれか一方に含まれていればよい。特に、冷却効果を向上させる観点からは、マウスピース部14が冷却セグメント12を有し、かつ、少なくとも該冷却セグメント12が上記の冷却剤を含むことが好ましく、フィルターセグメント13及び冷却セグメント12の両方が上記の冷却剤を含むことがより好ましい。
冷却セグメント12及びフィルターセグメント13の長さの割合を上記範囲内とすることで、冷却効果、生成した蒸気及びエアロゾルが冷却セグメント12の内壁に付着することによるロスを抑制する効果、及びフィルターの空気量及び香味の調整機能のバランスがとれて、良好な香味を得ることができる。
以下、フィルターセグメント及び冷却セグメントについて詳細に説明する。
フィルターセグメント13は、一般的なフィルターとしての機能を有していれば特に制限されず、例えば、合成繊維からなるトウ(単に「トウ」とも称する)や、紙等の材料を円柱状に加工したものを用いることができる。フィルターの一般的な機能とは、例えば、エアロゾル等を吸引する際に混ざる空気量の調整や、香味の軽減、ニコチンやタールの軽減等が挙げられるが、これらの機能を全て備えていることは要しない。また、紙巻きたばこ製品と比較して、生成される成分が少なく、また、たばこ充填物の充填率が低くなる傾向のある電気加熱式たばこ製品においては、濾過機能を抑えつつたばこ充填物の落下を防止する、ということも重要な機能の一つである。
フィルターセグメント全体に対する冷却剤の占める割合は、特に限定されず、通常5体積%以上であり、10体積%以上であることが好ましく、15体積%以上であることがより好ましい。また、通常100体積%以下であり、90体積%以下であることが好ましい。
また、フィルターセグメント13は、周方向の断面が中空(空洞)となるキャビティ(センターホール等)やリセス等のセクションを設けていてもよい。
フィルターセグメント13の周方向の断面形状の周の長さは、製品のサイズに合わせて適宜変更し得るが、通常14.0mm以上、27.0mm以下であり、15.0mm以上、26.0mm以下であることが好ましく、16.0mm以上、25.0mm以下であることがより好ましい。
フィルターセグメント13の軸方向の長さは、製品のサイズに合わせて適宜変更し得るが、通常15mm以上、35mm以下であり、17.5mm以上、32.5mm以下であることが好ましく、20.0mm以上、30.0mm以下であることがより好ましい。
上記の通気抵抗は、ISO標準法(ISO6565)に従って、例えばセルリアン社製フィルター通気抵抗測定器を使用して測定される。フィルターセグメント13の通気抵抗は、フィルターセグメント13の側面における空気の透過が行なわれない状態で一方の端面(第1端面)から他方の端面(第2端面)に所定の空気流量(17.5cc/min)の空気を流した際の、第1端面と第2端面との気圧差を指す。単位は、一般的にはmmH2Oで表す。フィルターセグメント13の通気抵抗とフィルターセグメント13の長さとの関係は、通常実施する長さ範囲(長さ5mm~200mm)においては比例関係であることが知られていて、長さが倍になれば、フィルターセグメント13の通気抵抗は倍になる。
カプセルの形態は、特段限定されず、例えば、易破壊性のカプセルであってよく、その形状は球であることが好ましい。カプセルに含まれる添加剤としては、上述した任意の添加剤を含んでいてもよいが、特に、香味剤や活性炭素を含むことが好ましい。また、添加剤として、煙を濾過する一助となる1種類以上の材料を加えてもよい。添加剤の形態は、特段限定されないが、通常、液体又は個体である。なお、添加剤を含むカプセルの使用は、当技術分野において周知である。易破壊性のカプセルおよびその製造方法は、本技術分野において周知である。
香味剤としては、例えば、メンソール、スペアミント、ペパーミント、フェヌグリーク、またはクローブ、中鎖脂肪酸トリグリセリド(MCT)等であってよい。香味剤は、メンソールである、またはメンソール等、又はこれらの組合せを用いることができる。
巻取紙の材料は特段制限されず、公知のものを用いることができ、また、炭酸カルシウム等の充填剤等を含んでいてよい。
巻取紙の厚さは、特段制限されず、通常20μm以上、140μm以下であり、30μm以上、130μm以下であることが好ましく、30μm以上、120μm以下であることがより好ましい。
巻取紙の坪量は、特段制限されず、通常20gsm以上、100gsm以下であり、22gsm以上、95gsm以下であることが好ましく、23gsm以上、90gsm以下であることがより好ましい。
また、巻取紙は、コーティングされていても、されていなくともよいが、強度や構造剛性以外の機能を付与できる観点からは、所望の材料でコーティングされることが好ましい。
冷却セグメント12は、たばこロッド部とフィルターセグメントとに隣接して挟持され、典型的には、円筒等の周方向の断面が中空(空洞)となるキャビティが設けられた棒状の部材である。
本実施形態の冷却セグメントは、本発明の一実施形態に係る冷却剤が上記キャビティに充填されたものであってよい。
冷却セグメント全体に対する冷却剤の占める割合は、特に限定されず、冷却効率を向上させる観点から、通常5体積%以上であり、10体積%以上であることが好ましく、15体積%以上であることがより好ましい。また、通常100体積%以下であり、90体積%以下であることが好ましい。
開孔Vが存在することで、使用時に外部から冷却部の内部に空気が流入し、たばこロッド部から流入する成分や空気の温度を下げることができる。さらに、冷却セグメントを設ける位置を冷却セグメントとフィルターセグメントとの境界から、冷却セグメント側の方向の4mm以上の領域内とすることにより、冷却能力を向上させるだけでなく、加熱により生成される成分の冷却セグメント内での滞留を抑制し、該成分のデリバリー量を向上させることができる。
なお、たばこロッド部にエアロゾル基材が用いられる場合、たばこロッド部が加熱されることで生じるエアロゾル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、エアロゾルが生成されることを促進させることができる。
また、同心円状に存在する開孔Vを1つの開孔群として扱った場合、開孔群は1つであってもよく、また、2つ以上であってもよい。開孔群が2つ以上存在する場合、加熱により生成される成分のデリバリー量向上の観点から、冷却セグメントとフィルターセグメントとの境界から、冷却セグメント側の方向の4mm未満の領域には開孔群を設けないことが好ましい。
また、非燃焼加熱式たばこ10が、たばこロッド部11、冷却セグメント12及びフィルターセグメント13がチップペーパー15で巻装されてなる態様である場合、チップペーパー15には、冷却セグメント12に設けられた開孔Vの直上の位置に開孔が設けられていることが好ましい。このような非燃焼加熱式たばこ10を作製する場合、開孔Vと重なるような開孔を設けたチップペーパー15を準備して巻装してもよいが、製造容易性の観点から、開孔Vを有さない冷却セグメント12を用いて非燃焼加熱式たばこ10を作製した後、冷却セグメント12及びチップペーパー15を同時に貫通する孔を開けることが好ましい。
開孔Vが存在する領域は、加熱により生成される成分のデリバリーを向上させる観点から、非燃焼加熱式たばこの吸口端から冷却セグメント方向に22mm以上離れた領域であることが好ましく、23mm以上であることが好ましく、24mm以上であることが好ましく、25mm以上であることがより好ましく、25.5mm以上であることがさらに好ましく、また、冷却機能を確保する観点から、35mm以下であることが好ましく、30mm以下であることがより好ましく、26mm以下であることがさらに好ましい。
また、冷却セグメント12とたばこロッド部11との境界を基準に考えると、冷却セグメント12の軸方向の長さが20mm以上である場合、開孔Vが存在する領域は、冷却機能を確保する観点から、冷却セグメント12とたばこロッド部11との境界から、冷却セグメント側の方向に2mm以上離れた領域であることが好ましく、5mm以上であることがより好ましく、10mm以上であることがさらに好ましく、14.5mm以上であることが特に好ましく、また、加熱により生成される成分のデリバリーを向上させる観点から、18mm以下であることが好ましく、16mm以下であることがより好ましく、14.5mm以下であることがさらに好ましい。
たばこロッド部11の態様は、公知の態様であれば特段制限されないが、通常、たばこ充填物を巻紙で巻装してなる態様である。たばこ充填物は特段限定されず、たばこ刻、再構成たばこシート等公知のものを用いることができる。また、たばこ充填物は、エアロゾル基材を含んでいてもよい。エアロゾル基材は、加熱されることによりエアロゾルを生成する基材であり、グリセリン、プロピレングリコール、トリアセチン、1,3-ブタンジオール、及びこれらの混合物が例示される。
たばこ充填物中のエアロゾル基材の含有量は、特に限定されず、十分にエアロゾルを生成させるとともに、良好な香味の付与の観点から、たばこ充填物の全量に対して通常5重量%以上であり、好ましくは10重量%以上であり、また、通常50重量%以下であり、好ましくは15重量%以上、25重量%以下である。
たばこ充填物を巻紙で巻装してなるたばこロッド部11は、柱状形状を有していることが好ましく、この場合には、たばこロッド部11の底面の幅に対するたばこロッド部11の長軸方向の高さで表されるアスペクト比が1以上であることが好ましい。
底面の形状は限定されず、多角、角丸多角、円、楕円等であってよく、幅は当該底面が円形の場合は直径、楕円形である場合は長径、多角形または角丸多角である場合は外接円の直径または外接楕円の長径である。たばこロッド部11を構成するたばこ充填物の高さは10~70mm程度、幅は4~9mm程度であることが好ましい。
巻紙の構成は、特段制限されず、一般的な態様とすることができ、例えば、パルプが主成分のものを挙げることができる。パルプとしては、針葉樹パルプや広葉樹パルプなどの木材パルプで抄造される以外にも、亜麻パルプ、大麻パルプ、サイザル麻パルプ、エスパルトなど一般的にたばこ製品用の巻紙に使用される非木材パルプを混抄して製造して得たものでもよい。
パルプの種類としては、クラフト蒸解法、酸性・中性・アルカリ亜硫酸塩蒸解法、ソーダ塩蒸解法等による化学パルプ、グランドパルプ、ケミグランドパルプ、サーモメカニカルパルプ等を使用できる。

該非燃焼加熱式たばこの巻紙として、その形状は正方形又は長方形を挙げることができる。
たばこ充填物を巻装するため(たばこロッド部を作製するため)の巻紙として利用する場合、一辺の長さとして12~70mm程度を挙げることができ、もう一辺の長さとして15~28mm、もう一辺の好ましい長さとして22~24mm、さらに好ましい長さとして23mm程度を挙げることができる。たばこ充填物を巻紙で柱状に巻装する際は、例えばw方向の巻紙の端部とその逆側の端部を2mm程度重ね合わせて糊付けすることで、柱状の紙管の形状となり、その中にたばこ充填物が充填されている形状となる。長方形形状の巻紙のサイズは、出来上がったたばこロッド部11のサイズによって決めることができる。
チップペーパーのように、たばこロッド部11とたばこロッド部11に隣接するその他の部材を連結して巻装するものである場合、一辺の長さとして20~60mm、もう一辺の長さとして15~28mmを挙げることができる。
巻紙では、好ましい坪量の範囲(25gsm以上、45gsm以下)において、填料が15重量%以上、45重量%以下であることが好ましい。
さらに、坪量が25gsm以上、35gsm以下のとき、填料が15重量%以上、45重量%以下であることが好ましく、坪量が35gsm超、45gsm以下のとき、填料が25重量%以上、45重量%以下であることが好ましい。
填料としては、炭酸カルシウム、二酸化チタン、カオリン等を使用することができるが、香味や白色度を高める観点等から炭酸カルシウムを使用することが好ましい。
助剤として、紙力増強剤を添加してもよく、例えば、ポリアクリルアミド、カチオンでんぷん、酸化でんぷん、CMC、ポリアミドエピクロロヒドリン樹脂、ポリビニルアルコール等を挙げられる。特に、酸化でんぷんについては、極少量用いることにより、通気度が向上することが知られている(特開2017-218699号公報)。
また、巻紙は、適宜コーティングされていてもよい。
チップペーパー15の構成は、特段制限されず、一般的な態様とすることができ、例えば、パルプが主成分のものを挙げることができる。パルプとしては、針葉樹パルプや広葉樹パルプなどの木材パルプで抄造される以外にも、亜麻パルプ、大麻パルプ、サイザル麻パルプ、エスパルトなど一般的にたばこ物品用の巻紙に使用される非木材パルプを混抄して製造して得たものでもよい。これらのパルプは、単独の種類で用いてもよく、複数の種類を任意の割合で組み合わせて用いてもよい。
また、チップペーパー15は一枚で構成されていてもよいが、複数枚以上で構成されていてもよい。
パルプの態様としては、クラフト蒸解法、酸性・中性・アルカリ亜硫酸塩蒸解法、ソーダ塩蒸解法等による化学パルプ、グランドパルプ、ケミグランドパルプ、サーモメカニカルパルプ等を使用できる。
なお、チップペーパー15は、後述する製造方法により製造したものでも、市販品を用いてもよい。
チップペーパー15の形状は、特段制限されず、例えば、正方形または長方形とすることができる。

チップペーパー15の通気度は、特段制限されないが、通常0コレスタユニット以上、30000コレスタユニット以下であり、0コレスタユニットより大きく、10000コレスタユニット以下であることが好ましい。なお、本明細書でいう通気度は、ISO 2965:2009に準拠して測定される値であり、紙の両面の差圧が1kPaのときに、1分ごとに面積1cm2を通過する気体の流量(cm3)で表される。1コレスタユニット(1C.U.)は、1kPa下においてcm3/(min・cm2)である。
上述した非燃焼加熱式たばこの製造方法は、特段制限されず、公知の方法を適用することができる。例えば、たばこロッド部及びマウスピース部をチップペーパーで巻き上げることで製造することができる。
本発明の別の実施形態に係る電気加熱式たばこ製品(単に「電気加熱式たばこ製品」とも称する。)は、ヒーター部材と、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、該ヒーター部材に接触するように挿入される、上記の非燃焼加熱式たばこと、から構成される、電気加熱式たばこ製品である。
電気加熱式たばこ製品の態様としては図2に示すような、非燃焼加熱式たばこ10の外周面を加熱する態様であってもよく、図3に示すような、非燃焼加熱式たばこ10におけるたばこロッド部11の内部から加熱する態様であってもよい。なお、図2及び図3に示す電気加熱式デバイス20には空気導入孔が設けられているが、ここでは図示しない。以下、図3を用いて電気加熱式たばこ製品30を説明する。なお、図2及び3における非燃焼加熱式たばこ10について、図1に示す各構成を表す符号は一部省略する。
電気加熱式たばこ製品30は、電気加熱式デバイス20の内部に配置された、ヒーター部材21に、上記で説明した非燃焼加熱式たばこ10が接触するように挿入されて使用される。
電気加熱式デバイス20は、例えば樹脂性の躯体24の内部に、電池ユニット22と制御ユニット23とを有する。
非燃焼加熱式たばこ10を電気加熱式デバイス20に挿入すると、たばこロッド部11の外周面が電気加熱式デバイス20のヒーター部材21と接触し、やがてたばこロッド部11の外周面の全部とチップペーパーの外周面の一部がヒーター部材21に接触する。
電気加熱式デバイス20のヒーター部材21は、制御ユニット23による制御により発熱する。その熱が非燃焼加熱式たばこ10のたばこロッド部11に伝わることで、たばこロッド部11のたばこ充填物に含まれるエアロゾル基材や香味成分等が揮発する。
図2に示すような、非燃焼加熱式たばこ10の外周面を加熱する態様である場合、上記のシート状ヒーター、平板状ヒーター、筒状ヒーターを用いることができる。一方で、図3に示すような、非燃焼加熱式たばこ10におけるたばこロッド部11の内部から加熱する態様である場合は、上記の平板状ヒーターや柱状ヒーター、錐状ヒーターを用いることができる。
ヒーター部材21の長軸方向の長さは、たばこロッド部11の長軸方向の長さをLmmとしたときに、L±5.0mmの範囲内とすることができる。ヒーター部材21の長軸方向の長さは、たばこロッド部11に十分に熱を伝え、たばこ充填物に含まれるエアロゾル基材や香味成分等を十分に揮発させる、すなわちエアロゾルデリバリーの観点から、Lmm以上であることが好ましく、香味等へ不所望な影響を及ぼす成分の発生を抑制する観点からL+0.5mm以下、L+1.0mm以下、L+1.5mm以下、L+2.0mm以下、L+2.5mm以下、L+3.0mm以下、L+3.5mm以下、L+4.0mm以下、L+4.5mm以下又はL+5.0mm以下であることが好ましい。
上記X(℃)は、加熱により生成される成分等のデリバリー量の観点から、80℃以上400℃以下であることが好ましい。具体的には、80℃、90℃、100℃、110℃、120℃、130℃、140℃、150℃、160℃、170℃、180℃、190℃、200℃、210℃、220℃、230℃、240℃、250℃、260℃、270℃、280℃、290℃、300℃、310℃、320℃、330℃、340℃、350℃、360℃、370℃、380℃、390℃、400℃とすることができる。
ヒーター部材21による加熱により、たばこロッド部11から生じるエアロゾル基材由来の成分や香味成分由来の成分等を含む蒸気は、冷却セグメント12やフィルターセグメント13等から構成されるマウスピース部14を通して使用者の口腔内に到達する。

溶液を全量添加した後は、温風給気と排気により、顆粒の水分含有量が3~9重量%前後になるまで流動させながら乾燥させた。
得られた冷却剤のプロピレングリコールの含有量は、28.0重量%であった。
上記の粒状活性炭及び冷却剤の物性を下記の表1に示す。
粒状活性炭をKuraraycoal GGS-N 28/70から、Kuraraycoal GGS-T 28/70に変更したこと以外は、実施例1と同様の方法で冷却剤を作製した。
当該活性炭(Kuraraycoal GGS-T 28/70)のBET比表面積は728m2/gであり、細孔容量は0.345mL/gであった。
また、得られた冷却剤のプロピレングリコールの含有量は、19重量%であった。
上記の粒状活性炭及び冷却剤の物性を下記の表1に示す。
図6に示す評価系での評価を実施することができる加熱空気負荷試験装置(遠藤サイエンス株式会社)を用いて冷却効果を評価した。具体的には、まず、圧縮空気(ドライ)が矢印Aから、水44に送られる。この際、圧縮空気は、圧力計44が0.65MPaを示すように送られ、また、レギュレータ42で圧力が0.5MPaとなるように圧力を制御し、かつ、圧縮空気の流量が10mL/min~20mL/minとなるようにサーマルマスフローメータ/コントローラ43(コフロック株式会社製、MODEL 8500)で制御した。
次に、水44に送られた空気は、三口フラスコ(50mL)52に送られる。この際、温度制御器45(株式会社八光電機製、ファインサーモ DGN-100)を用いて、温度計46で測定される水の温度が50℃となるように、パイプヒータ47(株式会社八光電機製、1KW)で水44が加熱され、空気の流量と水分量が制御された。さらに、三口フラスコ(50mL)52内の空気の温度を制御するため、温度調節器48(東邦電子株式会社製、温度調節器 TR2-303)及び少量流気体加熱器49(新熱工業株式会社製)、並びに温度調節器50(東邦電子株式会社製、温度調節器 TR2-303)及び少量流気体加熱器51(新熱工業株式会社製)を用いた。これらの手段により、三口フラスコ(50mL)52に送られた空気は、温度85.8℃、水分量82.8g/m3、及び流量2.59L/minとなるように制御された。
次に、三口フラスコ(50mL)52に送られた空気は、検体容器53を通り、三口フラスコ(50mL)54に送られ、最終的に矢印Bから解放される。この際、タッチ型レコーダ57(株式会社キーエンス製)を用いて、三口フラスコ(50mL)52内の温度を熱電対56(八光電機株式会社製、Kタイプ)で測定した温度と、三口フラスコ(50mL)54内の温度を熱電対55(八光電機株式会社製、Kタイプ)で測定した温度とを記録し、それらの温度の差から冷却効果を評価した(実際は、三口フラスコ(50mL)52内の温度が一定となるようにしているため、三口フラスコ(50ml)54内の温度で評価を行った)。評価時間(測定時間)は、約300秒とした。なお、検体容器53としては、内部に検体を入れることができる内径7.0mm、外径10.0mmのガラス管の通気方向の上下を目開き198μm、線径0.12mmのSUSメッシュ平織で覆ったものを用いた。
図6の検体容器53に何も入れなかった場合(空の場合)、並びに検体容器53に、市販の電気加熱式たばこ製品であるIQOS(フィリップ・モリス社製)において、冷却することを目的として用いられているPLA(ポリ乳酸)フィルムフィルター(PLAシート)、及びIQOSにおいて、冷却すること又は外周への熱伝達を抑えることを目的として用いられている中空フィルター、上記の実施例1で得られた冷却剤、並びに上記の実施例2で得られた冷却剤をそれぞれ入れた場合における冷却効果の評価結果を図7に示す。図7の横軸は測定時間、縦軸は三口フラスコ(50ml)54内の測定温度である。なお、上記のPLAシートにおいては、PLAシートからなるロッド部を有するiQOSから取り出した18mmロッド部のそのまま検体容器53に入れて測定を行い、また、上記の中空フィルターにおいては、中空フィルターのロッド部を有するiQOSから取り出した8mmのロッド部を6mmにカットしたものを3個採取し、これらを通気方向に重ねて18mmとしたものを検体容器53に入れて測定を行った。また、実施例1で得られた冷却剤及び実施例2で得られた冷却剤は、それぞれ0.7ccの量で入れて測定を行った。
これは、冷却剤粒子の除熱能力が高いこと、および多孔製ロッドが、この冷却剤粒子の除熱能力を生かす構造であることに起因すると考えられる。
