As raw material sheets used in such a flavor inhaler, a tobacco raw material formed into a sheet (see Patent Document 1) and a tobacco sheet bonded to an aluminum foil (see Patent Document 2) are known. It is

　シート状に形成されたたばこ原料は、それ単独では十分な強度を有することが困難である。たばこ原料中のパルプ繊維を増加させて強度を向上させることも考えられるが、その場合、たばこ原料中のたばこ成分の割合が減り、喫味が低下し得る。 A tobacco raw material formed into a sheet is difficult to have sufficient strength by itself. Although it is conceivable to increase the pulp fiber in the tobacco raw material to improve the strength, in this case, the ratio of the tobacco component in the tobacco raw material is decreased, which may deteriorate the smoking taste.
　また、紙層を有する基材にたばこシートを貼り合わせたものを製造するときは、原料シートは香味吸引器で加熱されて原料シートからの気化成分がユーザに供給されるので、喫味への影響を抑制するために接着剤を使用しないことが好ましい。 Further, when manufacturing a product in which a tobacco sheet is attached to a base material having a paper layer, the raw material sheet is heated by a flavor inhaler and vaporized components from the raw material sheet are supplied to the user.

　第１態様によれば、紙層上に結合剤を含む原料が塗布されるので、結合剤が紙層に染み込む。その後、原料に含まれる水分が蒸発すると、結合剤によって原料を紙層に接着させることができる。したがって、原料接着のための接着剤を使用することなく、原料シートの強度を向上させることができる。また、原料に圧力を加える必要もないので、所望の密度の原料を有する原料シートを製造することができる。 According to the first aspect, since the raw material containing the binder is applied onto the paper layer, the binder soaks into the paper layer. Afterwards, when the moisture contained in the raw material evaporates, the binding agent allows the raw material to adhere to the paper layer. Therefore, the strength of the raw material sheet can be improved without using an adhesive for bonding the raw material. Moreover, since it is not necessary to apply pressure to the raw material, it is possible to manufacture a raw material sheet having the raw material with a desired density.

The gist is to include
　第２態様によれば、基材シートに原料を連続的に塗布することができるので、原料シートを量産することができる。 According to the second aspect, since the raw material can be continuously applied to the base sheet, the raw material sheet can be mass-produced.

　第１６態様によれば、原料シートの強度を確保しながら、香味吸引器において効率よく原料を加熱することができる。紙層の厚さが０．０３ｍｍ未満であると、原料シートの強度が低下し、原料シートが破れやすくなり得る。また、紙層の厚さが０．１５ｍｍ超であると、紙層が厚くなりすぎるので、香味吸引器のヒータの熱が紙層の加熱に利用され、原料の加熱効率が低下し得る。 According to the sixteenth aspect, it is possible to efficiently heat the raw material in the flavor inhaler while ensuring the strength of the raw material sheet. If the thickness of the paper layer is less than 0.03 mm, the strength of the raw material sheet may be reduced, and the raw material sheet may be easily torn. On the other hand, if the thickness of the paper layer is more than 0.15 mm, the paper layer becomes too thick, and the heat of the heater of the flavor inhaler is used to heat the paper layer, which may reduce the heating efficiency of the raw material.
　第１７態様は、第１態様から第１６態様のいずれかにおいて、前記紙層の坪量は、２０ｇ／ｍ２以上１００ｇ／ｍ２以下である、ことを要旨とする。 A gist of a seventeenth aspect is that in any one of the first to sixteenth aspects, the basis weight of the paper layer is 20 g/m 2 or more and 100 g/m 2 or less.

If the basis weight of the paper layer is less than 20 g/m 2 , the strength of the raw material sheet may be lowered and the raw material sheet may be easily torn. Further, when the basis weight of the paper layer exceeds 100 g/m 2 , the heat of the heater of the flavor inhaler is used to heat the paper layer, which may reduce the heating efficiency of the raw material.
　第１８態様によれば、第１態様から第１７態様のいずれかにおいて、前記基材シートは、前記紙層に積層される、導電性を有する材料を含む導電層を有する、ことを要旨とする。 According to an eighteenth aspect, in any one of the first to seventeenth aspects, the gist is that the base sheet has a conductive layer containing a conductive material laminated on the paper layer. .
　シート状の原料の強度を向上させるために、アルミニウム箔に原料シートを貼り合わせることが考えられる。しかし、アルミニウム箔は、原料シートとの貼り合わせの際、しわになりやすく、破れやすいので、取扱いが困難である。また、たばこシートに高い圧力を加えることでアルミニウム箔にたばこシートを貼り付けることも考えられる。しかし、この場合たばこシートの密度が上昇するので、所望の密度のたばこシートを製造することが困難になる。第１８態様によれば、基材シートが導電層を有するものの、紙層上に結合剤を含む原料が塗布されるので、結合剤によって原料を紙層に接着させることができる。したがって、原料接着のための接着剤を使用することなく、原料シートの強度を向上させることができる。また、原料に圧力を加える必要もないので、所望の密度の原料を有する原料シートを製造することができる。さらに、基材シートが導電層を有するので、原料シートが香味吸引器で使用されるときの熱伝導効率（加熱効率）を向上させることができる。その結果、原料シートの使用時に原料からの蒸気又はエアロゾルのデリバリ効率が向上するので、原料使用量を低減することができる。また、香味吸引器が誘導コイルを備える場合には、誘導コイルによって原料シートを誘導加熱することができる。また、導電層により、原料シートの強度を向上させることもできる。なお、導電性を有する材料としては、例えばアルミニウム、ＳＵＳ、カーボン等を含むことができる。 In order to improve the strength of the sheet-shaped raw material, it is conceivable to attach the raw material sheet to the aluminum foil. However, aluminum foil is difficult to handle because it is easily wrinkled and torn when it is attached to the raw material sheet. It is also conceivable to attach the tobacco sheet to the aluminum foil by applying high pressure to the tobacco sheet. However, in this case, the density of the tobacco sheet increases, making it difficult to produce a tobacco sheet with a desired density. According to the eighteenth aspect, although the base sheet has the conductive layer, the material containing the binder is applied onto the paper layer, so that the material can be adhered to the paper layer by the binder. Therefore, the strength of the raw material sheet can be improved without using an adhesive for bonding the raw material. Moreover, since it is not necessary to apply pressure to the raw material, it is possible to manufacture a raw material sheet having the raw material with a desired density. Furthermore, since the base sheet has a conductive layer, the heat conduction efficiency (heating efficiency) can be improved when the raw material sheet is used in a flavor inhaler. As a result, the delivery efficiency of vapor or aerosol from the raw material is improved when the raw material sheet is used, so that the amount of raw material used can be reduced. Moreover, when the flavor suction device is provided with an induction coil, the raw material sheet can be induction-heated by the induction coil. Moreover, the strength of the raw material sheet can be improved by the conductive layer. In addition, as a material having conductivity, for example, aluminum, SUS, carbon, or the like can be included.

It can also function as a suitable susceptor when inductively heated by an induction coil in a flavor inhaler. Furthermore, it is possible to prevent the resistance from becoming too large when cutting or bending the raw material sheet.

In the drawings described below, the same or corresponding components are denoted by the same reference numerals, and duplicate descriptions are omitted. FIG. 1 is a schematic enlarged cross-sectional view of a raw material sheet 100 according to this embodiment. As illustrated, the raw material sheet 100 has a base sheet 10 and a raw material 20 . In this embodiment, the base sheet 10 has a conductive layer 12 containing a conductive material and a paper layer 14 laminated on the conductive layer 12 . Specifically, the base sheet 10 may be a metal laminated paper formed by bonding the conductive layer 12 and the paper layer 14 together. As the conductive material, known materials such as aluminum, stainless steel, iron, cobalt, nickel, manganese, chromium, silicon, carbon, or alloys combining them can be used. Since the base sheet 10 has the conductive layer 12 , the heat of the heater of the flavor inhaler can be efficiently transferred to the raw material 20 . Moreover, since the base sheet 10 has the conductive layer 12, the conductive layer 12 can be used as a susceptor for induction heating. As illustrated, in the raw material sheet 100 of the present embodiment, the raw material 20 is provided on the paper layer 14 of the base sheet 10 . Although the base sheet 10 has the conductive layer 12 in this embodiment, the base sheet 10 may not have the conductive layer 12 .
　紙層１４は、例えばパルプ紙などの紙であり得る。また、本実施形態において、紙層１４には、たばこ繊維を含まない、不織布等の繊維層が含まれ得る。紙層１４の厚さは任意であるが、０．０３ｍｍ以上０．１５ｍｍ以下であることが好ましい。紙層１４の厚さがこの範囲であれば、原料シート１００の強度を確保しながら、香味吸引器において効率よく原料２０を加熱することができる。紙層１４の厚さが０．０３ｍｍ未満であると、原料シート１００の強度が低下し、原料シート１００が破れやすくなり得る。また、紙層１４の厚さが０．１５ｍｍ超であると、紙層１４が厚くなりすぎるので、香味吸引器のヒータの熱が紙層１４の加熱に利用され、原料２０の加熱効率が低下し得る。 The paper layer 14 may be paper such as pulp paper. Also, in this embodiment, the paper layer 14 may include a fibrous layer such as a non-woven fabric that does not contain tobacco fibers. Although the thickness of the paper layer 14 is arbitrary, it is preferably 0.03 mm or more and 0.15 mm or less. If the thickness of the paper layer 14 is within this range, it is possible to efficiently heat the raw material 20 in the flavor inhaler while ensuring the strength of the raw material sheet 100 . If the thickness of the paper layer 14 is less than 0.03 mm, the strength of the raw material sheet 100 may be lowered and the raw material sheet 100 may be easily torn. Further, when the thickness of the paper layer 14 exceeds 0.15 mm, the paper layer 14 becomes too thick, so the heat of the heater of the flavor suction device is used to heat the paper layer 14, and the heating efficiency of the raw material 20 is lowered. can.
　また、紙層１４の坪量は任意であるが、２０ｇ／ｍ２以上１００ｇ／ｍ２以下であることが好ましい。紙層１４の坪量がこの範囲であれば、原料シート１００の強度を確保しながら、香味吸引器において効率よく原料２０を加熱することができる。紙層１４の坪量が２０ｇ／ｍ２未満であると、原料シート１００の強度が低下し、原料シート１００が破れやすくなり得る。また、紙層１４の坪量が１００ｇ／ｍ２超であると、香味吸引器のヒータの熱が紙層１４の加熱に利用され、原料２０の加熱効率が低下し得る。紙層１４の坪量は、３０ｇ／ｍ２以上５０ｇ／ｍ２以下であることがより好ましい。 Moreover, the basis weight of the paper layer 14 is arbitrary, but is preferably 20 g/m 2 or more and 100 g/m 2 or less. If the basis weight of the paper layer 14 is within this range, the material 20 can be efficiently heated in the flavor inhaler while ensuring the strength of the material sheet 100 . If the basis weight of the paper layer 14 is less than 20 g/m 2 , the strength of the raw material sheet 100 may be lowered, and the raw material sheet 100 may be easily torn. Further, when the basis weight of the paper layer 14 exceeds 100 g/m 2 , the heat of the heater of the flavor inhaler is used to heat the paper layer 14, and the heating efficiency of the raw material 20 may decrease. More preferably, the basis weight of the paper layer 14 is 30 g/m 2 or more and 50 g/m 2 or less.
　導電層１２の厚さは、好ましくは５μｍ以上２０μｍ以下である。導電層１２の厚さがこの範囲であると、導電材料の使用量を抑えながら適切な熱伝達を発揮することができる。また、香味吸引器においてインダクションコイルによって誘導加熱されるときに適切なサセプタとして機能し得る。さらに、原料シート１００の裁断又は曲げの際の抵抗が大きくなりすぎるのが抑制され得る。導電層１２の厚さは、より好ましくは５μｍ以上１５μｍ以下であり、具体的には１０μｍ程度であり得る。 The thickness of the conductive layer 12 is preferably 5 μm or more and 20 μm or less. When the thickness of the conductive layer 12 is within this range, appropriate heat transfer can be exhibited while suppressing the amount of conductive material used. It can also function as a suitable susceptor when inductively heated by an induction coil in a flavor inhaler. Furthermore, excessive increase in resistance during cutting or bending of the raw material sheet 100 can be suppressed. The thickness of the conductive layer 12 is more preferably 5 μm or more and 15 μm or less, and specifically can be about 10 μm.
　原料シート１００は、図１に示す状態で香味吸引器のヒータによって、片面又は両面が加熱され得る。また、原料シート１００は、折りたたまれた状態で香味吸引器のヒータによって加熱されてもよい。原料シート１００は、香味吸引器のインダクションコイルによって導電層１２が誘導加熱されることで加熱されてもよい。原料シート１００の原料２０が加熱されることで、エアロゾル源又は香味源の蒸気及びエアロゾルを発生し得る。 The raw material sheet 100 can be heated on one side or both sides by the heater of the flavor sucker in the state shown in FIG. Moreover, the raw material sheet 100 may be heated by the heater of the flavor inhaler in a folded state. The raw material sheet 100 may be heated by induction heating of the conductive layer 12 by an induction coil of a flavor sucker. Heating the raw material 20 of the raw material sheet 100 can generate an aerosol source or flavor source vapor and aerosol.
　次に、図１に示した原料シート１００の製造方法について説明する。図２は、原料シート１００の製造方法を示す概略図である。原料シート１００を製造するには、まず、基材シート１０を準備する。図２に示すように、ロール状に巻かれた基材シート１０を準備することが好ましい。これにより、基材シート１０への後述する原料２０の塗布を連続的に行うことができるので、原料シート１００を量産することができる。 Next, a method for manufacturing the raw material sheet 100 shown in FIG. 1 will be described. FIG. 2 is a schematic diagram showing a method of manufacturing the raw material sheet 100. As shown in FIG. To manufacture the raw material sheet 100, first, the base sheet 10 is prepared. As shown in FIG. 2, it is preferable to prepare a base sheet 10 wound into a roll. As a result, the material sheet 100 can be mass-produced because the material 20 described below can be continuously applied to the base material sheet 10 .
　続いて、基材シート１０の紙層１４上に、結合剤及び香味源を含む原料２０を塗布する。香味源としては、例えばたばこを使用することができる。たばこは、例えば粉体であり得る。粉体のたばこのメジアン径（Ｄ５０）は、５μｍ以上１００μｍ以下であることが好ましい。結合剤としては、例えば、グアーガム、キサンタンガム、ＣＭＣ（カルボキシメチルセルロース）、ＣＭＣ－Ｎａ（カルボキシメチルセルロースのナトリウム塩）、プルランおよびヒドロキシプロピルセルロース（ＨＰＣ）、メチルセルロース、ヒドロキシルメチルセルロース等を使用することができる。原料２０に添加され得る結合剤の重量％は、例えば、原料２０の重量に対して、好ましくは０％超６０％以下、より好ましくは０％超１０％以下である。 Subsequently, raw material 20 containing a binder and a flavor source is applied onto paper layer 14 of base sheet 10 . Tobacco, for example, can be used as the flavor source. Tobacco can be, for example, a powder. The median diameter (D50) of powdered tobacco is preferably 5 μm or more and 100 μm or less. As binders, for example, guar gum, xanthan gum, CMC (carboxymethylcellulose), CMC-Na (sodium salt of carboxymethylcellulose), pullulan and hydroxypropylcellulose (HPC), methylcellulose, hydroxylmethylcellulose and the like can be used. The weight percent of the binder that can be added to the raw material 20 is, for example, preferably more than 0% and 60% or less, more preferably more than 0% and 10% or less, relative to the weight of the raw material 20 .
　具体的には、図２に示すように、ノズル３１から結合剤及び香味源を含んでスラリー状になっている原料２０が基材シート１０の紙層１４上に供給され、ナイフコータ３３によって所定の厚さに原料２０が塗布される。図２に示す例に限らず、任意の方法で原料２０が紙層１４に塗布され得る。これにより、紙層１４上に結合剤を含む原料２０が塗布されるので、結合剤が紙層１４に染み込む。その後、原料２０に含まれる水分の一部が蒸発すると、結合剤によって原料２０を紙層１４に接着させることができる。したがって、原料２０の接着のための接着剤を使用することなく、原料シート１００の強度を向上させることができる。また、原料２０に圧力を加える必要もないので、所望の密度の原料２０を有する原料シート１００を製造することができる。さらに、基材シート１０が導電層１２を有するので、原料シート１００が香味吸引器で使用されるときの熱伝導効率（加熱効率）を向上させることができる。その結果、原料シート１００の使用時に原料２０からの蒸気又はエアロゾルのデリバリ効率が向上するので、原料２０の使用量を低減することができる。また、香味吸引器が誘導コイルを備える場合には、誘導コイルによって原料シート１００を誘導加熱することができる。また、導電層１２により、原料シート１００の強度を向上させることもできる。 Specifically, as shown in FIG. 2, a raw material 20 in a slurry state containing a binder and a flavor source is supplied from a nozzle 31 onto the paper layer 14 of the base sheet 10, and is coated by a knife coater 33. A raw material 20 is applied to a thickness. The raw material 20 can be applied to the paper layer 14 by any method other than the example shown in FIG. As a result, the raw material 20 containing the binder is applied onto the paper layer 14 , so that the binder permeates into the paper layer 14 . After some of the moisture contained in the material 20 evaporates, the material 20 can be adhered to the paper layer 14 by the binder. Therefore, the strength of the raw material sheet 100 can be improved without using an adhesive for bonding the raw material 20 . Moreover, since it is not necessary to apply pressure to the raw material 20, it is possible to manufacture the raw material sheet 100 having the raw material 20 with a desired density. Furthermore, since the base sheet 10 has the conductive layer 12, the heat conduction efficiency (heating efficiency) can be improved when the raw material sheet 100 is used in a flavor inhaler. As a result, the delivery efficiency of the vapor or aerosol from the raw material 20 is improved when the raw material sheet 100 is used, so the amount of the raw material 20 used can be reduced. Moreover, when the flavor suction device is provided with an induction coil, the raw material sheet 100 can be induction-heated by the induction coil. Moreover, the strength of the raw material sheet 100 can be improved by the conductive layer 12 .
　原料２０には、多価アルコール、酸、又は香料が添加されていてもよい。これにより、原料シート１００の香味又は喫味を増加又は調整することができる。具体的には、原料２０に多価アルコールが添加される場合、原料シート１００を香味吸引器において加熱したときに原料２０から発生する蒸気又はエアロゾルの量を増加させることができる。多価アルコールには、グリセリン、プロピレングリコール、ソルビトール、キシリトール及びエリスリトールが含まれ得る。これらの多価アルコールは、単独で、または２種以上を組み合わせて、原料２０に使用することができる。 A polyhydric alcohol, an acid, or a fragrance may be added to the raw material 20. Thereby, the flavor or smoking taste of the raw material sheet 100 can be increased or adjusted. Specifically, when a polyhydric alcohol is added to the raw material 20, the amount of vapor or aerosol generated from the raw material 20 when the raw material sheet 100 is heated in the flavor inhaler can be increased. Polyhydric alcohols may include glycerin, propylene glycol, sorbitol, xylitol and erythritol. These polyhydric alcohols can be used for the raw material 20 individually or in combination of two or more.
　基材シート１０は搬送され、搬送されている基材シート１０の紙層１４上に原料２０が塗布されることが好ましい。具体的には、図２に示すように、原料２０が塗布された基材シート１０、即ち原料シート１００がロール状に巻き取られることで、基材シート１０がロールから繰り出されて所定の方向に搬送され得る。このように搬送されている基材シート１０に原料２０がノズル３１から供給され、ナイフコータ３３が原料２０を所定の厚さに塗布される。これにより、基材シート１０に原料２０を連続的に塗布することができるので、原料シート１００を量産することができる。 It is preferable that the base sheet 10 is conveyed and the raw material 20 is applied onto the paper layer 14 of the base sheet 10 being conveyed. Specifically, as shown in FIG. 2, the base sheet 10 coated with the raw material 20, that is, the raw material sheet 100 is wound into a roll, so that the base sheet 10 is unwound from the roll and rolled in a predetermined direction. can be transported to The raw material 20 is supplied from the nozzle 31 to the base sheet 10 being conveyed in this way, and the knife coater 33 coats the raw material 20 to a predetermined thickness. As a result, the raw material 20 can be continuously applied to the base sheet 10, so that the raw material sheet 100 can be mass-produced.
　また、基材シート１０に塗布された原料２０が乾燥されることが好ましい。具体的には、基材シート１０に塗布された原料２０が加熱され得る。図２に示すように、原料２０が塗布された基材シート１０の紙層１４側にヒータ３５が配置され、基材シート１０の紙層１４側からヒータ３５により原料２０が加熱され得る。ヒータ３５として、例えば赤外線ヒータ等の任意の加熱装置が採用され得る。これにより、原料２０が加熱されることで、原料２０に含まれる水分の蒸発を促進することができるので、原料２０が乾燥して紙層１４に接着するまでの時間を短縮することができ、原料シート１００の生産性を向上させることができる。図２に示す例に限らず、基材シート１０の導電層１２側から原料２０が加熱されてもよいし、基材シート１０の紙層１４側及び導電層１２側の両側から原料２０が加熱されてもよい。また、ヒータ３５に限らず、送風器が原料２０に送風して、乾燥を促進してもよい。即ち、ヒータ３５に限らず、原料２０の乾燥を促進し得る任意の装置が使用され得る。基材シート１０の原料２０が乾燥されるとき、基材シート１０に引っ張り応力を加えることが好ましい。これにより、原料２０が乾燥したときに基材シート１０が収縮してカールすることが抑制され得る。 Also, it is preferable that the raw material 20 applied to the base sheet 10 is dried. Specifically, the raw material 20 applied to the base sheet 10 can be heated. As shown in FIG. 2 , a heater 35 is arranged on the paper layer 14 side of the base sheet 10 coated with the raw material 20 , and the raw material 20 can be heated by the heater 35 from the paper layer 14 side of the base sheet 10 . Any heating device such as an infrared heater may be employed as the heater 35 . As a result, by heating the raw material 20, the evaporation of the moisture contained in the raw material 20 can be promoted, so the time required for the raw material 20 to dry and adhere to the paper layer 14 can be shortened. The productivity of the raw material sheet 100 can be improved. The raw material 20 may be heated from the conductive layer 12 side of the base sheet 10 without being limited to the example shown in FIG. may be Moreover, not only the heater 35 but also a blower may blow air to the raw material 20 to promote drying. That is, not only the heater 35, but any device capable of promoting the drying of the raw material 20 can be used. It is preferable to apply a tensile stress to the base sheet 10 when the raw material 20 of the base sheet 10 is dried. This can prevent the base sheet 10 from shrinking and curling when the raw material 20 dries.
　基材シート１０には、多価アルコール、酸、又は香料が添加されてもよい。これにより、原料シート１００の香味又は喫味を増加又は調整することができる。具体的には、基材シート１０に多価アルコールが添加される場合、原料シート１００を香味吸引器において加熱したときに原料２０から発生する蒸気又はエアロゾルの量を増加させることができる。また、上記乾燥工程の後に、原料２０が塗布された基材シート１０に、多価アルコール、酸、又は香料が添加されることが好ましい。この場合、塗布された原料２０が乾燥された後に多価アルコール等が添加されるので、シート表面に添加された多価アルコール等が、原料２０の水分と共に乾燥することが抑制され得る。 A polyhydric alcohol, acid, or fragrance may be added to the base sheet 10 . Thereby, the flavor or smoking taste of the raw material sheet 100 can be increased or adjusted. Specifically, when a polyhydric alcohol is added to the base sheet 10, the amount of vapor or aerosol generated from the raw material 20 when the raw material sheet 100 is heated in the flavor inhaler can be increased. Moreover, it is preferable that a polyhydric alcohol, an acid, or a fragrance is added to the base sheet 10 coated with the raw material 20 after the drying step. In this case, since the polyhydric alcohol or the like is added after the applied raw material 20 is dried, it is possible to prevent the polyhydric alcohol or the like added to the sheet surface from drying together with the water content of the raw material 20 .
　基材シート１０には、複数の貫通孔を形成してもよい。これにより、原料シート１００の表面積を増加させることができるので、原料シート１００から生じる蒸気又はエアロゾル量を増加させることができる。また、原料シート１００に貫通孔が形成されることで、原料シート１００の内部に染み込んだ原料２０が効率よく蒸発することができる。この貫通孔は、基材シート１０に原料２０が塗布される前に形成されてもよいし、原料２０が塗布された後に形成されてもよい。また、複数の貫通孔は、具体的には、基材シート１０にレーザ孔又はニードルにより形成され得る。これにより、図２に示すような製造プロセスにおいて原料シート１００に貫通孔を形成する工程を組み込むことができ、当該工程を自動化することができる。 A plurality of through holes may be formed in the base sheet 10 . As a result, the surface area of the raw material sheet 100 can be increased, so that the amount of vapor or aerosol generated from the raw material sheet 100 can be increased. In addition, since the through-holes are formed in the material sheet 100, the material 20 that permeates the inside of the material sheet 100 can be efficiently evaporated. The through holes may be formed before the raw material 20 is applied to the base sheet 10, or may be formed after the raw material 20 is applied. Also, the plurality of through-holes can be specifically formed in the base sheet 10 by laser holes or needles. As a result, the step of forming through-holes in the raw material sheet 100 can be included in the manufacturing process as shown in FIG. 2, and the step can be automated.
　また、基材シート１０には、表面積を増加させる表面処理を施してもよい。これにより、原料シート１００の表面積が増加するので、原料シート１００を加熱したときに生じる蒸気又はエアロゾルを増加させることができる。この表面処理は、基材シート１０に原料２０が塗布される前に行われてもよいし、原料２０が塗布された後に行われてもよい。また、基材シート１０には、エンボス加工が施されてもよい。これにより、原料シート１００の表面積をエンボス加工により増加させることができる。 In addition, the base sheet 10 may be surface-treated to increase its surface area. As a result, the surface area of the raw material sheet 100 is increased, so that the amount of vapor or aerosol generated when the raw material sheet 100 is heated can be increased. This surface treatment may be performed before the raw material 20 is applied to the base sheet 10, or may be performed after the raw material 20 is applied. Also, the base sheet 10 may be embossed. Thereby, the surface area of the raw material sheet 100 can be increased by embossing.
　原料２０には、パルプ繊維が含まれてもよい。これにより、原料２０に含まれる水分が蒸発したときに、原料２０のパルプ繊維と紙層１４の繊維とが絡み合い、原料２０を紙層１４により確実に接着させることができる。また、原料シート１００の強度を向上させることができる。他方、原料２０にはパルプ繊維が含まれなくてもよい。この場合、その分だけ原料２０における香味源の割合が増加するので喫味の向上が期待される。また、原料２０には、乳酸、パルミチン酸、又は安息香酸等の酸を加えてもよい。 The raw material 20 may contain pulp fibers. As a result, when the moisture contained in the raw material 20 evaporates, the pulp fibers of the raw material 20 and the fibers of the paper layer 14 are entangled, and the raw material 20 can be more reliably adhered to the paper layer 14 . Moreover, the strength of the raw material sheet 100 can be improved. On the other hand, feedstock 20 may be free of pulp fibers. In this case, the ratio of the flavor source in the raw material 20 is increased by that amount, so an improvement in smoking taste is expected. Also, an acid such as lactic acid, palmitic acid, or benzoic acid may be added to the raw material 20 .
　図２に示すように、乾燥して原料２０が接着した基材シート１０、即ち原料シート１００は、ロール状に巻き取られることが好ましい。これにより、原料シート１００をコンパクトにすることができ、保管スペースを縮小することができる。また、後段の工程において、ロール状の原料シート１００を繰り出すことで、連続した加工プロセスを実行することができる。なお、図２に示す原料シート１００は、その搬送方向と直交する両端部に原料２０が塗布されていない領域１００ａを有する。 As shown in FIG. 2, the base sheet 10 to which the raw material 20 has been dried and adhered, ie, the raw material sheet 100, is preferably wound into a roll. Thereby, the raw material sheet 100 can be made compact, and the storage space can be reduced. Further, in a subsequent step, by feeding out the roll-shaped raw material sheet 100, a continuous processing process can be executed. Note that the raw material sheet 100 shown in FIG. 2 has regions 100a on which the raw material 20 is not applied at both ends perpendicular to the conveying direction.
　原料２０が塗布された基材シート１０、即ち原料シート１００は、さらに後段の工程において切断されてもよい。これにより、所定サイズの原料シート１００を製造することができる。図３は、原料２０が塗布された基材シート１０を切断するプロセスを示す概略図である。図３に示すように、原料２０が塗布された基材シート１０が繰り出されて所定方向に搬送されながら、搬送方向に沿って切断され得る。具体的には、ロール状に巻かれた原料シート１００が繰り出されて所定方向に搬送され、搬送経路に１つ以上のスリットカッタ３７が配置され得る。原料２０が塗布された基材シート１０は、搬送されながらスリットカッタ３７によって搬送方向に沿って切断され得る。これにより、原料２０が塗布された基材シート１０を搬送方向に沿って連続的に切断することができる。したがって、搬送方向に沿った長尺の原料シート１００を製造することができるので、例えば長尺の原料シート１００をロール状に巻き取ることができる。 The base sheet 10 coated with the raw material 20, that is, the raw material sheet 100 may be cut in a subsequent step. Thereby, the raw material sheet 100 of a predetermined size can be manufactured. FIG. 3 is a schematic diagram showing the process of cutting the base sheet 10 coated with the raw material 20. As shown in FIG. As shown in FIG. 3, the base sheet 10 coated with the raw material 20 can be fed out and conveyed in a predetermined direction while being cut along the conveying direction. Specifically, the raw material sheet 100 wound in a roll shape is unwound and conveyed in a predetermined direction, and one or more slit cutters 37 can be arranged in the conveying path. The base sheet 10 coated with the raw material 20 can be cut along the conveying direction by the slit cutter 37 while being conveyed. Thereby, the base sheet 10 coated with the raw material 20 can be cut continuously along the conveying direction. Therefore, since it is possible to manufacture a long raw material sheet 100 along the conveying direction, for example, the long raw material sheet 100 can be wound into a roll.
　図３に示すようにスリットカッタ３７が複数設けられる場合には、複数のスリットカッタ３７は、搬送方向に直交する、基材シート１０の幅方向に隣接して配置され得る。図３に示すように、基材シート１０の搬送方向と直交する方向における基材シート１０の両端部は、搬送方向に沿って切断して除去されることが好ましい。これにより、図３に示すように、この両端部が原料２０が塗布されていない領域１００ａを含む場合に、この領域１００ａを除去することができる。また、基材シート１０に原料２０を塗布するにあたり、基材シート１０の両端部は原料２０の厚みが不均一になる傾向がある。したがって、基材シート１０の両端部を切断して除去することで、原料２０の厚みが比較的均一な部分を原料シート１００として残すことができる。 When a plurality of slit cutters 37 are provided as shown in FIG. 3, the plurality of slit cutters 37 can be arranged adjacent to each other in the width direction of the base sheet 10, which is orthogonal to the conveying direction. As shown in FIG. 3, both ends of the base sheet 10 in the direction perpendicular to the conveying direction of the base sheet 10 are preferably removed by cutting along the conveying direction. As a result, as shown in FIG. 3, when both ends include regions 100a where the raw material 20 is not applied, the regions 100a can be removed. Further, when applying the raw material 20 to the base sheet 10 , the thickness of the raw material 20 tends to be uneven at both ends of the base sheet 10 . Therefore, by cutting and removing both ends of the base sheet 10 , a portion of the raw material 20 having a relatively uniform thickness can be left as the raw material sheet 100 .
　図３に示すように、切断された基材シート１０は巻き取られることが好ましい。これにより、ロール状の原料シート１００を製造することができるので、後段の工程において連続した加工プロセスを実行することができる。具体的には、例えば、原料シート１００を所定長さに切断する場合に、ロール状の原料シート１００を繰り出しながら、搬送方向において等間隔に原料シート１００を連続的に切断することができる。 As shown in FIG. 3, the cut base sheet 10 is preferably wound up. As a result, since the roll-shaped raw material sheet 100 can be manufactured, a continuous processing process can be performed in the subsequent steps. Specifically, for example, when cutting the raw material sheet 100 to a predetermined length, the raw material sheet 100 can be continuously cut at equal intervals in the conveying direction while the rolled raw material sheet 100 is fed out.
