Definitions
- the present invention relates to a cartridge for a non-combustion heat-not-burn tobacco product and a non-combustion heat-not-burn tobacco product provided with the cartridge detachably attached.
- Non-combustion heat-not-burn tobacco products that atomize an aerosol source without combustion are known (for example, Patent Document 1 and Patent Document 2).
- Such non-combustion heat-not-burn tobacco products include an atomization unit for atomizing an aerosol source and a cartridge having a flavor source containing a tobacco filling.
- the cartridge is replaceable and is connected to the atomization unit. Then, the aerosol atomized by the atomizing unit passes through while contacting the flavor source in the cartridge, so that the flavor component is delivered to the user together with the aerosol.
- the flavor source containing the tobacco filling in the cartridge is heated to about 30 ° C. to 40 ° C. at the time of use. Has been done.
- the amount of flavor components delivered to the user is insufficient compared to ordinary cigarettes, or the user feels the "flavor inhibition feeling" described later. Therefore, it is desired to suppress the feeling of flavor inhibition while ensuring the delivery amount of the flavor component above a certain level. Then, in order to solve such a problem, the first acid dissociation constant is 4.
- Patent Document 3 A technique for adding an acid having a boiling point of 0 or more and 6.0 or less and a boiling point of 366 ° C or more and 600 ° C or less has been reported (Patent Document 3).
- Patent Document 1 and Patent Document 2 the amount of flavor component delivered to the user is insufficient as compared with ordinary cigarettes, which is a problem peculiar to non-combustion heat-not-burn tobacco products, and the user is informed. No study has been made on the feeling of flavor inhibition. Further, in Patent Document 3, in a mode in which the tobacco filling containing the tobacco chopped and the aerosol source is heated to 160 ° C. to 170 ° C., the amount of evaporation of the flavor component is sufficient and the feeling of flavor inhibition is suppressed. It is shown to be.

From the viewpoint of heat resistance of the container and from the viewpoint of maintaining the effect of suppressing the flavor inhibition feeling by the acid contained in the tobacco filling, the mode of setting the temperature to less than 120 ° C., 100 ° C. or lower, and 50 ° C. or lower will be mentioned. Can be done. The lower and upper limits of the heating temperature of these tobacco fillings can be arbitrarily combined.
本発明の実施形態に係る非燃焼加熱式たばこ製品のカートリッジに含まれるたばこ充填物は、120℃以上、250℃以下の沸点を有する酸を、たばこ充填物の総重量を100重量%としたときに、0.25重量%以上、5.0重量%以下含有する。
酸を含有させる対象がたばこ充填物ではなく、例えば、エアロゾル源である場合、霧化部を構成する電熱線が酸と直接触れる構成となり、その結果、電熱線が腐食しやすくなるといった問題や、電熱線の発する熱による酸の変化により香味阻害感の抑制効果が低下するといった問題が発生するおそれがある。
一方で、たばこ充填物が、上記特定の沸点を有する酸を特定量含有することで、上述した電熱線の腐食や香味阻害感の抑制効果の低下といった問題を回避しつつ、非燃焼加熱式たばこ製品の使用時に、使用者にデリバリーされる香味成分量を確保し、かつ、香味阻害感を抑制できる。 <Acid contained in tobacco filling>
The tobacco filling contained in the cartridge of the non-combustion heat-not-burn tobacco product according to the embodiment of the present invention is an acid having a boiling point of 120 ° C. or higher and 250 ° C. or lower, and the total weight of the tobacco filling is 100% by weight. In addition, it contains 0.25% by weight or more and 5.0% by weight or less.
When the object to contain the acid is not a tobacco filler, for example, an aerosol source, the heating wire constituting the atomizing part is in direct contact with the acid, and as a result, the heating wire is easily corroded. There is a possibility that a problem such as a decrease in the effect of suppressing the feeling of flavor inhibition may occur due to a change in acid due to the heat generated by the heating wire.
On the other hand, by containing a specific amount of the acid having the specific boiling point in the tobacco filling, the non-combustion heating type tobacco can be avoided while avoiding the above-mentioned problems such as corrosion of the heating wire and reduction of the effect of suppressing flavor inhibition. When the product is used, the amount of flavor component delivered to the user can be ensured, and the feeling of flavor inhibition can be suppressed.
上記の香味阻害感を抑制する方法として、たばこ充填物中に酸を添加する方法が知られており、そのメカニズムは、次のように考えられている。すなわち、たばこ充填物中に含まれる、香味を阻害する成分と酸とが、加熱により気相に放出され、気相中で結合することにより、これを吸引する使用者の香味阻害感を受ける器官、すなわち、口腔内~気管~肺までの器官に、結合しにくくなるためと考えられている。 Flavor inhibition generally means that when a non-combustion heat-not-burn tobacco product is used, the user receives a stimulus different from the stimulus peculiar to tobacco, or a physiological spontaneous movement such as "muse" occurs. It means that it occurs. It is considered that this is because a component that inhibits flavor when present in the gas phase is contained, and when a non-combustion heat-not-burn tobacco product is used, the amount of such a component that inhibits flavor in the gas phase. It is believed that the user feels a sense of flavor inhibition when the balance with the amount of atomized aerosol is lost.
As a method of suppressing the above-mentioned flavor-inhibiting feeling, a method of adding an acid to a tobacco filling is known, and the mechanism is considered as follows. That is, the flavor-inhibiting component and the acid contained in the tobacco filling are released into the gas phase by heating, and when they are combined in the gas phase, the organ that inhales the flavor-inhibiting feeling of the user. That is, it is thought that it becomes difficult to connect to the organs from the oral cavity to the trachea to the lungs.
前記酸の沸点が120℃未満である場合、酸自身が有する特有の匂いが、香味に影響を与える可能性があり、また、カートリッジの蔵置期間中に酸が揮発してしまう可能性があることや、本発明に係る非燃焼加熱式たばこ製品の使用時におけるたばこ充填物の加熱により、該使用の初期段階で大半の酸が揮発することで、該使用の初期から末期まで通した香味阻害感の抑制効果が得られない。また、前記酸の沸点が250℃を超える場合、本発明に係る非燃焼加熱式たばこ製品におけるたばこ充填物の加熱温度との差が大きく、気相に放出される酸の量が不足するため、香味阻害感の抑制が困難となる。
前記酸の沸点は、たばこ充填物の加熱温度が上昇した場合でも香味阻害感の抑制効果を非燃焼加熱式たばこ製品の使用の初期から末期まで通して得られる観点から、150℃以上であることが好ましく、175℃以上であることがより好ましく、200℃以上であることが特に好ましい。一方で、前記酸の沸点は、気相に放出される酸の量を十分に確保する観点から、240℃以下であることが好ましく、230℃以下であることが好ましく、220℃以下であることが特に好ましい。
なお、本明細書における「沸点」とは、760mmHgの圧力下における沸点を意味するものとする。 In the above mechanism, it is important for the present inventors that when the tobacco filling is heated, a sufficient amount of acid for binding to a flavor-inhibiting component is released into the gas phase. I thought. Therefore, among various acids that can be used as food additives, an acid suitable for suppressing the feeling of flavor inhibition during use of the non-combustion heat-not-burn tobacco product according to the embodiment of the present invention is selected based on its boiling point. As a result of the search, it was found that an acid having a boiling point of 120 ° C. or higher and 250 ° C. or lower is suitable for suppressing the feeling of flavor inhibition.
If the boiling point of the acid is less than 120 ° C., the peculiar odor of the acid itself may affect the flavor, and the acid may volatilize during the storage period of the cartridge. In addition, when the non-combustion heat-not-burn tobacco product according to the present invention is used, most of the acid volatilizes in the initial stage of the use due to the heating of the tobacco filling, so that the flavor is inhibited from the early stage to the final stage of the use. The suppressive effect of is not obtained. Further, when the boiling point of the acid exceeds 250 ° C., the difference from the heating temperature of the tobacco filling in the non-combustion heating type tobacco product according to the present invention is large, and the amount of acid released into the gas phase is insufficient. It becomes difficult to suppress the feeling of flavor inhibition.
The boiling point of the acid should be 150 ° C. or higher from the viewpoint that the effect of suppressing the feeling of flavor inhibition can be obtained from the early stage to the final stage of use of the non-combustion heated tobacco product even when the heating temperature of the tobacco filling is increased. 175 ° C. or higher is more preferable, and 200 ° C. or higher is particularly preferable. On the other hand, the boiling point of the acid is preferably 240 ° C. or lower, preferably 230 ° C. or lower, and 220 ° C. or lower, from the viewpoint of sufficiently securing the amount of acid released into the gas phase. Is particularly preferable.
The "boiling point" in the present specification means the boiling point under a pressure of 760 mmHg.
一般的に、たばこ充填物に添加された酸は、たばこ充填物中の香味成分と結びつき、塩を形成することで安定化すると考えられている。また、このように安定化した酸と香味成分の塩は、加熱されても気相に放出されにくくなると考えられている。したがって、たばこ充填物に対する酸の含有量が多すぎる場合、非燃焼加熱式たばこ製品の使用時において、使用者にデリバリーされる香味成分量が不十分となる傾向にある。
前記酸の含有量が、上記範囲内にあることで、本発明の実施形態に係る非燃焼加熱式たばこ製品の使用時において、使用者にデリバリーされる香味成分量を確保できる。一方で、前記酸の含有量が0.25重量%未満である場合、香味阻害感を十分に抑制することができない。また、前記酸の含有量が5.50重量%を超える場合、使用者にデリバリーされる香味成分量を十分に確保することができない。また、酸の含有量が5.00重量%を超えると酸を添加する際の取り扱いが難しくなる。
前記酸の含有量は、たばこ充填物の総重量を100重量%としたときに、香味阻害感の効果を十分に得る観点から、0.50重量%以上であることが好ましく、0.75重量%以上であることがより好ましく、また、使用者にデリバリーされる香味成分量を十分に確保する観点から、4.00重量%以下であることが好ましい。また、より良好な香味とする観点から、3.00重量%以下であることがより好ましい。 The acid content is 0.25% by weight or more and 5.50% by weight or less when the total weight of the tobacco filling is 100% by weight.
It is generally believed that the acid added to the tobacco filling binds to the flavor components in the tobacco filling and stabilizes by forming salts. Further, it is considered that the acid and the salt of the flavor component stabilized in this way are less likely to be released into the gas phase even when heated. Therefore, if the acid content in the tobacco filling is too high, the amount of flavor component delivered to the user tends to be insufficient when using the non-combustion heat-not-burn tobacco product.
When the acid content is within the above range, the amount of flavor component delivered to the user can be ensured when the non-combustion heat-not-burn tobacco product according to the embodiment of the present invention is used. On the other hand, when the content of the acid is less than 0.25% by weight, the flavor-inhibiting sensation cannot be sufficiently suppressed. Further, when the content of the acid exceeds 5.50% by weight, the amount of the flavor component delivered to the user cannot be sufficiently secured. Further, if the acid content exceeds 5.00% by weight, it becomes difficult to handle when adding the acid.
The acid content is preferably 0.50% by weight or more, preferably 0.75% by weight, from the viewpoint of sufficiently obtaining the effect of flavor inhibition when the total weight of the tobacco filling is 100% by weight. % Or more, and preferably 4.00% by weight or less from the viewpoint of sufficiently ensuring the amount of flavor component delivered to the user. Further, from the viewpoint of obtaining a better flavor, it is more preferably 3.00% by weight or less.
酸解離定数pKaは、一般的に、その値が小さいほど強い酸であることを示す。
前記酸の酸解離定数pKaが上記範囲内にあると、それほど強い酸でないことから、取り扱いが容易であり、たばこ充填物に添加する際の製造適正に優れている。また、酸解離定数pKaが3.0未満である比較的強い酸がたばこ充填物に添加された場合、酸と香味成分との結びつきが強固となり、加熱による気相への香味の放出量が減少することが考えられる。
なお、本明細書における酸の酸解離定数pKaは、25℃の水中における第一酸解離定数の測定値であり、例えば、国際公開第2017/203686号明細書の表1に記載された値を使用できる。 The acid, acid dissociation constant pK a is 3.0 or more, preferably 6.0 or less, 3,5 or more, and more preferably 5.0 or less.
Acid dissociation constant pK a generally indicates a strong acid a smaller value.
When the acid dissociation constant pK a of the acid is in the above range, since it is not so strong acid, it is easy to handle, and manufacturability is excellent when added to the tobacco filler. Further, when a relatively strong acid having an acid dissociation constant pKa of less than 3.0 is added to the tobacco filling, the bond between the acid and the flavor component is strengthened, and the amount of flavor released to the gas phase by heating is reduced. It is conceivable to do.
Incidentally, the acid dissociation constant pK a of the acid in the present specification is a measurement of a first acid dissociation constant in water at 25 ° C., for example, the values listed in Table 1 of WO 2017/203686 Pat Can be used.
リン酸のような無機酸;乳酸、安息香酸、レブリン酸、ピルビン酸、リノレン酸のような有機酸。
これらの中でも、有機酸が好ましく、乳酸又は安息香酸がより好ましい。
また、乳酸は、鏡像異性体としてL-乳酸とD-乳酸が存在するが、これらの一方を用いてもよく、両方を併用することもでき、ラセミ体(DL体)の乳酸を用いることもできる。
上記の酸は単独で用いてもよく、2種以上を併用してもよい。 As the acid, any acid can be used as long as it satisfies the above-mentioned physical characteristics, and for example, the following acids can be used.
Inorganic acids such as phosphoric acid; organic acids such as lactic acid, benzoic acid, levulinic acid, pyruvate, linolenic acid.
Among these, organic acids are preferable, and lactic acid or benzoic acid is more preferable.
Lactic acid includes L-lactic acid and D-lactic acid as enantiomers, but one of these may be used, both may be used in combination, and racemic (DL) lactic acid may be used. can.
The above acids may be used alone or in combination of two or more.
前記香味成分としてはニコチンを挙げることができ、たばこ充填物に含まれるニコチンの定量については、ドイツ標準化機構DIN 10373に準ずる方法で行うことができる。 Cartridges for non-combustion heat-not-burn tobacco products include tobacco fillings. Tobacco fillings contain flavor components. The content of the flavor component is not particularly limited, but from the viewpoint of making it easy to confirm the effect of suppressing the flavor inhibitory feeling, when the total weight of the tobacco filling is 100% by weight, 1.0% by weight or more, 10. It is 0% by weight or less, preferably 1.5% by weight or more and 8.0% by weight or less, and more preferably 2.0% by weight or more and 6.5% by weight or less.
Nicotine can be mentioned as the flavor component, and the quantification of nicotine contained in the tobacco filling can be carried out by a method according to the German standardization organization DIN 10373.
以下、収穫されたたばこ葉が、非燃焼加熱式たばこ製品で利用される種々の形態になるまでの流れを詳述するが、本願発明のたばこ充填物が、この記載に限定されることはない。 As used herein, the term "tobacco filling" refers to aged tobacco leaves (hereinafter, "processed tobacco leaves") prepared in various forms used in non-combustion heat-not-burn tobacco products. Refers to those filled in the manner described in. Here, the "aged tobacco leaf" refers to aged tobacco leaf before being processed into various forms used in non-combustion heat-not-burn tobacco products. Further, the “filled material” refers to an container described later.
Hereinafter, the flow until the harvested tobacco leaves are in various forms used in non-combustion heat-not-burn tobacco products will be described in detail, but the tobacco filler of the present invention is not limited to this description. ..
非燃焼加熱式たばこ製品に使用されるたばこの品種は、様々なものを用いることができる。例えば、黄色種、バーレー種、オリエント種、在来種、その他のニコチアナ-タバカム系品種、ニコチアナ-ルスチカ系品種を挙げることができる。これらの品種は、単独で用いることもできるが、目的とする香味を得るために、たばこ葉の収穫から、熟成済たばこ葉を非燃焼加熱式たばこ製品で利用される種々の形態(すなわち、加工済たばこ葉)とするまでの過程で、ブレンドして用いることもできる。
前記たばこの品種の詳細は、「たばこの事典、たばこ総合研究センター、2009.3.31」に開示されている。 <Tobacco varieties>
Various varieties of tobacco used in non-combustion heat-not-burn tobacco products can be used. For example, yellow varieties, Burley varieties, Orient varieties, native varieties, other Nicotian-Tabacam varieties, and Nicotian-Rustica varieties can be mentioned. These varieties can be used alone, but in order to obtain the desired flavor, the aged tobacco leaves are used in non-combustion heat-not-burn tobacco products from the harvest of the tobacco leaves in various forms (ie, processed). It can also be blended and used in the process of making (finished tobacco leaves).
Details of the tobacco varieties are disclosed in "Tobacco Encyclopedia, Tobacco Academic Studies Center, 2009.3.31".
たばこの各品種において、たばこ葉は、例えば、原産地、植物内での配置、色、表面の状態、大きさ、および形状といった各特徴により等級分けされる。また、たばこ葉には300を超える化学成分が含まれていると考えられており、品種が異なるたばこ間の化学的特性は異なるものとなる。また、同一の品種のたばこであっても、等級が異なると、その化学的特性が異なる場合もある。
そこで、所望の特徴、及び所望の化学的特性を有する加工済たばこ葉を得るために、上記のブレンドやクロスブレンドが行われる場合もある。 Generally, "blend" means a mixture of tobacco belonging to the same variety or different varieties, but in the present specification, the combination of different aged tobacco leaves and different processed tobacco leaves is referred to as "blend". Sometimes referred to. Also, blending tobacco of the same variety but with different grades may be particularly referred to as "cross-blending".
In each tobacco variety, tobacco leaves are graded according to characteristics such as origin, arrangement within the plant, color, surface condition, size, and shape. In addition, it is considered that tobacco leaves contain more than 300 chemical components, and the chemical properties of different varieties of tobacco are different. In addition, even tobacco of the same variety may have different chemical properties depending on the grade.
Therefore, the above-mentioned blending or cross-blending may be performed in order to obtain a processed tobacco leaf having a desired characteristic and a desired chemical property.
収穫されたたばこ葉が、初期の段階で受ける処理としては、例えば、キュアリングや原料工場における処理及び熟成などを挙げることができる。 <Treatment of tobacco leaves>
Examples of the treatment that the harvested tobacco leaves receive in the initial stage include curing, treatment in a raw material factory, and aging.
キュアリングを受けたたばこ葉はケースに梱包され、一定期間、倉庫で保管された後、原料工場へ輸送される。
なお、ベンゾ[a]ピレン及び低分子カルボン酸の含有量が少なく、特定の香味成分が多く含まれるたばこ葉を得るために、上述のキュアリングに代えて、収穫されたたばこ葉に国際公開第2018/139068号に記載の処理を行ってもよい。 Tobacco leaves are generally subjected to a process called curing in the early stages after harvesting. Curing usually involves steps such as drying and humidity control, and also includes activating the actions of various enzymes contained in tobacco leaves.
The cured tobacco leaves are packed in a case, stored in a warehouse for a certain period of time, and then transported to a raw material factory.
In addition, in order to obtain tobacco leaves containing a small amount of benzo [a] pyrene and low-molecular-weight carboxylic acid and a large amount of a specific flavor component, instead of the above-mentioned curing, the harvested tobacco leaves are released internationally. The process described in 2018/139068 may be performed.
なお、たばこ葉をラミナ及び中骨等に加工した後にケース詰めして熟成させることを除骨後熟成と称することがある。一方で、原料工場に輸送されたたばこ葉に対し、除骨、分離加工を行わずに、ケース詰めして熟成させ、熟成後に除骨、分離加工を行うことを熟成後除骨と称することもある。 After being unpacked, the tobacco leaves transported to the raw material factory are usually subjected to treatments such as humidity control, deboning, and separation to become lamina and middle bone. After that, the re-dried lamina, middle bones, etc. are packed in a case and stored for a long time in a warehouse. The process of long-term storage in this warehouse is sometimes referred to as aging. The aging period varies depending on the type of tobacco used, the desired flavor of the non-combustion heat-not-burn tobacco product, and the temperature during aging, but is generally 1 year or more and 2 years or less. As defined above, aged tobacco leaves are referred to as aged tobacco leaves.
It should be noted that processing tobacco leaves into lamina, middle bone, etc., and then packing them in a case and aging them may be referred to as post-bone aging. On the other hand, tobacco leaves transported to a raw material factory are packed in a case and aged without being deboned or separated, and the deboning and separation processing after aging is also called post-aging deboning. be.

たばこ充填物は、加工済たばこ葉、すなわち、上述のたばこ顆粒やたばこ刻、たばこシートなどが被充填物(本願発明における「収容体」)に所定の態様で充填されたものを指す。 <Tobacco filling>
The tobacco filling refers to processed tobacco leaves, that is, those in which the above-mentioned tobacco granules, tobacco chopped, tobacco sheets, etc. are filled in a filling material (“container” in the present invention) in a predetermined manner.
本発明の実施形態において、たばこ充填物のカートリッジにおける充填率は、通常、40体積%以上であり、50体積%以上であることが好ましく、60体積%以上であることがより好ましい。また、充填率は、通常、80体積%以下であり、70体積%以下であることが好ましい。該充填率が40体積%未満であると、十分な香味成分量を確保することが困難となる。一方で、該充填率が80体積%よりも大きいと、吸引時の圧力効果が大きくなり吸いづらくなる他、製造効率が低下する。充填率は、収容体の中でたばこ充填物の収容部となる部分の全容積に対する、たばこ充填物の体積の割合により算出される。 The filling rate of the tobacco filling in the cartridge can be appropriately set according to the morphology of the processed tobacco leaves to be filled, the desired flavor, the aeration resistance, and the like.
In the embodiment of the present invention, the filling rate of the tobacco filling in the cartridge is usually 40% by volume or more, preferably 50% by volume or more, and more preferably 60% by volume or more. The filling rate is usually 80% by volume or less, preferably 70% by volume or less. If the filling rate is less than 40% by volume, it becomes difficult to secure a sufficient amount of flavor components. On the other hand, if the filling rate is larger than 80% by volume, the pressure effect at the time of suction becomes large and it becomes difficult to suck, and the production efficiency decreases. The filling rate is calculated by the ratio of the volume of the tobacco filling to the total volume of the portion of the container that serves as the container for the tobacco filling.
たばこ充填物(A)は、収容体に充填または配置されたたばこ顆粒から構成される。
たばこ顆粒は、カートリッジにおいて、移動不能に充填されてもよく、移動可能に配置されてもよい。
「移動不能に充填される」とは、たばこ顆粒が収容体に密に充填されることで、カートリッジを上下左右に動かしたとしても移動しないことを意味する。一方で、「移動可能に配置される」とは、カートリッジを上下左右に動かした際に、収容体の中をたばこ顆粒が移動することを意味する。したがって、たばこ顆粒が、移動可能に配置される場合、たばこ充填物(A)は流動性を有する。 <Tobacco filling (A)>
The tobacco filling (A) is composed of tobacco granules filled or placed in the container.
The tobacco granules may be immovably packed or movably arranged in the cartridge.
"Filled immovably" means that the tobacco granules are densely packed in the containment so that the cartridge does not move even if it is moved up, down, left and right. On the other hand, "movably arranged" means that the tobacco granules move in the housing when the cartridge is moved up, down, left and right. Therefore, when the tobacco granules are arranged in a movable manner, the tobacco filling (A) has fluidity.
たばこ充填物(B)は、収容体に充填されたたばこ刻から構成される。
たばこ充填物(B)が収容体に充填される態様は、特に制限されないが、ストランドタイプ刻以外のたばこ刻は、通常、収容体の中でランダム方向に充填される。一方で、ストランドタイプ刻は、その長手方向が収容体の長手方向と略水平となるように充填される。 <Tobacco filling (B)>
The tobacco filling (B) is composed of tobacco chopped filled in the container.
The mode in which the tobacco packing material (B) is filled in the container is not particularly limited, but the tobacco carvings other than the strand type carving are usually filled in the container in a random direction. On the other hand, the strand type engraving is filled so that its longitudinal direction is substantially horizontal to the longitudinal direction of the accommodating body.
たばこ充填物(C)は、収容体に充填されたたばこシートから構成される。たばこシートの枚数は、1枚であってもよく、2枚以上であってもよい。 <Tobacco filling (C)>
The tobacco filling (C) is composed of a tobacco sheet filled in the container. The number of tobacco sheets may be one or two or more.
「同心状に配置されている」とは、すべてのたばこシートの中心が略同じ位置にあるように配置されていることをいう。また、たばこシートの枚数は、特に制限されないが、2枚、3枚、4枚、5枚、6枚、又は7枚である態様を挙げることができる。 In the case where the tobacco filling material (C) is composed of two or more tobacco sheets, for example, a plurality of tobacco sheets whose one side has the same length as the longitudinal direction of the container can be used. An embodiment in which the housing is wound in a direction orthogonal to the longitudinal direction of the housing so as to be arranged concentrically can be mentioned.
"Concentrically arranged" means that the centers of all tobacco sheets are arranged so as to be substantially in the same position. The number of tobacco sheets is not particularly limited, and examples thereof include two, three, four, five, six, or seven tobacco sheets.
複数のたばこシート間に、当該たばこシートが接触しない非接触部を設けるために、例えば、エンボス加工したたばこシートを用いる、隣接するたばこシート同士の全面を接着せずに積層する、隣接するたばこシート同士の一部を接着して積層する、あるいは隣接するたばこシート同士の全面あるいは一部を、巻上げ成形後に剥がれるように軽度に接着して積層することで積層体を調製する方法を挙げることができる。 In the method for producing the tobacco filler (C) described above, it is preferable that the laminate is prepared so that a non-contact portion is formed between the adjacent tobacco sheets after winding molding. If there is a non-contact portion (gap) between the plurality of tobacco sheets that the tobacco sheet does not contact, it is possible to secure a flavor flow path and improve the delivery efficiency of the flavor component. On the other hand, since the heat from the heater can be transferred to the outer tobacco sheet through the contact portions of the plurality of tobacco sheets, high heat transfer efficiency can be ensured.
In order to provide a non-contact portion between a plurality of tobacco sheets so that the tobacco sheets do not come into contact with each other, for example, an embossed tobacco sheet is used, and the entire surfaces of adjacent tobacco sheets are laminated without being adhered to each other. A method of preparing a laminate by adhering a part of each other and laminating, or by slightly adhering and laminating the entire surface or a part of adjacent tobacco sheets so as to be peeled off after winding molding can be mentioned. ..
各たばこ充填物にエアロゾル生成基材が含まれる場合、その含有量は、たばこ充填物100重量%に対して、15重量%以下を例示でき、別の態様では10重量%以下であり、さらに別の態様では8重量%以下である。また、上述したとおり、たばこ充填物にエアロゾル生成基材が含有されていない態様(0重量%)も挙げることもできる。 The tobacco fillers (A) to (C) described above may or may not contain an aerosol-producing base material as an aerosol source. The type of aerosol-forming substrate is not particularly limited, and extracts from various natural products and / or their constituents can be selected depending on the application. Aerosol-forming substrates include, but are not limited to, for example, glycerin, propylene glycol, triacetin, 1,3-butanediol, and mixtures thereof.
When each tobacco filling contains an aerosol-forming substrate, the content thereof can be exemplified as 15% by weight or less with respect to 100% by weight of the tobacco filling, and in another embodiment, it is 10% by weight or less, and further. In the above aspect, it is 8% by weight or less. Further, as described above, an embodiment (0% by weight) in which the aerosol-forming base material is not contained in the tobacco filling can also be mentioned.
また、前記酸を上記のたばこ充填物に添加する方法についても、特に限定されない。
一例として、収容体に充填されたたばこ充填物に、収容体の開口部から該たばこ充填物の中心部分にシリンジ針を挿入し、前記酸を含む溶液を噴射することで添加する方法を挙げることができる。この添加方法によれば、前記酸を含む溶液が、たばこ充填物の全体に浸透するため、たばこ充填物の全体に均一に前記酸を含有させることができる。
また、収容体に充填する前の、柱状に形成した加工済たばこ葉の表面に前記酸の溶液を塗布する方法を挙げることもできる。この添加方法によれば、たばこ充填物の表面に前記酸を多く含有させることができる。
さらに他の例として、熟成済たばこ葉、又は加工済たばこ葉を、回転ローターを有する加香機に供給し、これを回転攪拌させながら前記酸の溶液を噴霧し、混合することで添加する方法を挙げることができる。この添加方法によれば、たばこ充填物の全体に均一に前記酸を添加することができる。
上記の添加方法において、前記酸の溶媒としては、水の他に、エタノールやプロピレングリコール等を用いることができるが、前記酸との親和性が高いことからプロピレングリコールを用いることが好ましい。 The timing of adding the acid to the above-mentioned tobacco fillings (A) to (C) is not particularly limited, and even if it is added when forming processed tobacco leaves (that is, tobacco granules, tobacco chopped, tobacco sheet). Often, the processed tobacco leaves may be added when or after filling the container.
Further, the method of adding the acid to the tobacco filling is not particularly limited.
As an example, a method of adding a syringe needle to the tobacco filling filled in the container by inserting a syringe needle into the central portion of the tobacco filling through the opening of the container and injecting the solution containing the acid can be mentioned. Can be done. According to this addition method, the solution containing the acid permeates the entire tobacco filling, so that the acid can be uniformly contained in the entire tobacco filling.
Further, a method of applying the acid solution to the surface of the processed tobacco leaf formed in a columnar shape before filling the container can be mentioned. According to this addition method, the surface of the tobacco filling can contain a large amount of the acid.
As yet another example, a method in which aged tobacco leaves or processed tobacco leaves are supplied to a perfume machine having a rotating rotor, and the acid solution is sprayed and mixed while rotating and stirring the mixture. Can be mentioned. According to this addition method, the acid can be uniformly added to the entire tobacco filling.
In the above addition method, ethanol, propylene glycol or the like can be used as the solvent for the acid in addition to water, but propylene glycol is preferably used because of its high affinity with the acid.
たばこ充填物を収容する収容体は、筒状であり、所定方向に沿って延びるエアロゾル流路を形成する。図7に示すように、たばこ充填物31Aを収容する収容体31は、所定方向Aに沿って延びる第2流路30Xを形成する。エアロゾルに香味を付与するたばこ充填物31Aは、第2流路30X内に収容される。ここで、エアロゾル流路(所定方向A)に直交する断面において、エアロゾル源21Aを貯留するリザーバ21の体積を確保するために、第1流路20Xのサイズが小さいことが好ましい。従って、エアロゾル流路(所定方向A)に亘って一定の断面積を有する外枠体24にカートリッジ30が収容されるケースにおいては、結果として、第2流路30Xのサイズは、上述した第1流路20Xのサイズよりも大きくなりやすい。
なお、図8において、収容体31の所定方向Aに直交する断面は、円形で示されているが、この形状は円に限定されず、収容体の所定方向に直交する断面の形状は多角、角丸多角、円、楕円等であってよい。すなわち、筒状には、円筒のみならず、楕円筒、多角筒、角丸多角筒といった形状が含まれる。 <Container>
