Description

たばこ成形体及び香味吸引具Tobacco molding and flavor suction tool
　本発明は、たばこ成形体及びたばこ成形体を備える香味吸引具に関する。 The present invention relates to a tobacco molded body and a flavor suction tool including the tobacco molded body.
　従来、たばこ粉末等をたばこ原料として用いたたばこ成形体を備える香味吸引具が知られている。 Conventionally, there has been known a flavor suction device provided with a tobacco molded body using tobacco powder or the like as a tobacco raw material.
　この種の香味吸引具は、たばこ成形体と、煙管などのホルダとを有しており、かかるたばこ成形体をホルダに装着して利用される。具体的に、ユーザは、かかるたばこ成形体をホルダに装着した後に、たばこ成形体の端面に着火する。そして、ユーザは、燃焼するたばこ成形体から放出される香味成分を、ホルダーを介して吸引することができる。 This type of flavor suction tool has a tobacco molded body and a holder such as a smoke tube, and is used by mounting the tobacco molded body on the holder. Specifically, the user ignites the end surface of the tobacco molded body after mounting the tobacco molded body on the holder. And the user can suck | inhale the flavor component discharge | released from the tobacco molded object which burns through a holder.
　また、上述のたばこ成形体には、様々なものが提案されている（例えば、特許文献１参照）。 Further, various types of the above-described tobacco molded body have been proposed (see, for example, Patent Document 1).
　特許文献１には、中空の円筒状に形成されたたばこ成形体が開示されている。かかるたばこ成形体は、中空の円筒状に形成されていることから、中空でないものと比べて、たばこ成形体の外壁を薄くできるため、たばこ成形体の端面における着火性が向上する。 Patent Document 1 discloses a tobacco molded body formed in a hollow cylindrical shape. Since such a tobacco molded body is formed in a hollow cylindrical shape, the outer wall of the tobacco molded body can be made thinner as compared with a non-hollow one, so that the ignitability at the end face of the tobacco molded body is improved.
　また、近年では、助燃剤としてカーボンを含む炭素熱源と、炭素熱源からの熱流によってたばこの香味成分を放出する香味発生源と、炭素熱源と香味発生源とを保持するホルダとを有する非燃焼型の香味吸引具も提案されている（例えば、特許文献２）。 Further, in recent years, a non-combustion type having a carbon heat source containing carbon as a combusting agent, a flavor generation source that releases a tobacco flavor component by a heat flow from the carbon heat source, and a holder that holds the carbon heat source and the flavor generation source. A flavor suction device has also been proposed (for example, Patent Document 2).
　特許文献２には、柱状の炭素熱源が、外壁と、外壁の内部において、軸方向に貫通する複数の貫通孔を区画する隔壁とを有する構成が開示されている。特許文献２の炭素熱源は、外壁の厚さと、複数の貫通孔を区画する隔壁の厚さとを薄く形成して、炭素熱源の着火性及び燃焼持続性を向上させている。 Patent Document 2 discloses a configuration in which a columnar carbon heat source has an outer wall and a partition wall that partitions a plurality of through holes penetrating in the axial direction inside the outer wall. In the carbon heat source of Patent Document 2, the thickness of the outer wall and the thickness of the partition walls defining the plurality of through holes are formed thin, and the ignitability and combustion sustainability of the carbon heat source are improved.
　しかしながら、上述の従来技術では、次のような問題があった。 However, the above-described conventional technology has the following problems.
　特許文献１に開示されるたばこ成形体は、中空の円筒状に形成されていることから、たばこ成形体の外壁を薄くすれば、たばこ成形体の端面における着火性及び燃焼持続性については一定の効果があるが、燃焼部分が外壁のみであるため、たばこ成形体の断面において、燃焼部分の面積が十分に確保できない。そのため、燃焼するたばこ成形体から、香味成分が十分に放出されず、ユーザに与えられる香味成分による味わい（喫味）が低下してしまう。 Since the tobacco molded body disclosed in Patent Document 1 is formed in a hollow cylindrical shape, if the outer wall of the tobacco molded body is thinned, the ignitability and combustion sustainability at the end face of the tobacco molded body are constant. Although effective, since the combustion part is only the outer wall, the area of the combustion part cannot be sufficiently ensured in the cross section of the tobacco molded article. Therefore, the flavor component is not sufficiently released from the burning tobacco molded article, and the taste (tasting) due to the flavor component given to the user is lowered.
　また、特許文献２の炭素熱源は、外壁の厚さと、外壁の内部に設けられる隔壁の厚さを薄く形成できるため、着火性及び燃焼持続性を向上させつつ、燃焼部分の面積を確保でできる。 Moreover, since the carbon heat source of patent document 2 can form the thickness of an outer wall and the thickness of the partition provided inside an outer wall thinly, it can ensure the area of a combustion part, improving ignitability and combustion sustainability. .
　しかし、特許文献２の炭素熱源は、香味発生源に熱流を送るために、助燃剤としてカーボンを含む。したがって、かかる炭素熱源と、たばこ成形体とは、それぞれの組成が異なるため、単に、かかる構成をたばこ成形体に適用しただけでは、ユーザに与えられる香味成分による味わいを確保して、着火性及び燃焼持続性を向上させるための対策として十分でない。 However, the carbon heat source of Patent Document 2 contains carbon as a combustion aid in order to send a heat flow to the flavor generation source. Therefore, since the composition of the carbon heat source and the tobacco molded product are different from each other, simply applying such a configuration to the tobacco molded product ensures the taste by the flavor component given to the user, and the ignitability and It is not enough as a measure to improve the sustainability of combustion.

　（たばこ成形体の構成）
　次に、実施形態に係るたばこ成形体１０の構成について具体的に説明する。 (Configuration of tobacco molding)
Next, the structure of the tobacco molded body 10 according to the embodiment will be specifically described.
　図２は、実施形態に係るたばこ成形体１０の斜視図である。図３は、たばこ成形体１０の軸方向Ｌに直交する横断方向Ｄにおける断面図である。図４は、たばこ成形体１０の側面図である。 FIG. 2 is a perspective view of the tobacco molded body 10 according to the embodiment. FIG. 3 is a cross-sectional view in the transverse direction D perpendicular to the axial direction L of the tobacco molded body 10. FIG. 4 is a side view of the tobacco molded body 10.
　実施形態に係るたばこ成形体１０は、中心軸Ａｘに沿った軸方向Ｌに延びる柱状に形成される。たばこ成形体１０は、少なくともたばこ原料を含む。 The tobacco molded body 10 according to the embodiment is formed in a column shape extending in the axial direction L along the central axis Ax. The tobacco molded body 10 includes at least a tobacco raw material.
　また、たばこ成形体１０は、軸方向Ｌに対向する一対の端面１０ａ、１０ｂと、軸方向Ｌに延びる筒状の外壁１１と、外壁１１の内部において、一対の端面１０ａ、１０ｂ間を貫通する複数の貫通孔５０を区画する隔壁１２とを有する。 Further, the tobacco molded body 10 penetrates between the pair of end surfaces 10a and 10b inside the outer wall 11 and the pair of end surfaces 10a and 10b facing in the axial direction L, the cylindrical outer wall 11 extending in the axial direction L, and the inside. And a partition wall 12 defining a plurality of through holes 50.
　一対の端面１０ａ、１０ｂのそれぞれは、一方が着火面であり、他方がホルダ２０に挿入される。 One of the pair of end faces 10 a and 10 b is an ignition surface and the other is inserted into the holder 20.
　外壁１１と隔壁１２とは、軸方向Ｌに沿って延びるように形成されている。外壁１１は、たばこ成形体１０の横断方向Ｄにおいて、最も外側に位置する。外壁１１は、中心軸Ａｘを中心とした周方向において、後述する溝状貫通孔５２によって、複数に分断されていてもよい。 The outer wall 11 and the partition wall 12 are formed so as to extend along the axial direction L. The outer wall 11 is located on the outermost side in the transverse direction D of the tobacco molded body 10. The outer wall 11 may be divided into a plurality of portions by a groove-like through hole 52 described later in the circumferential direction around the central axis Ax.
　隔壁１２は、たばこ成形体１０の横断方向Ｄにおいて、外壁１１の内側に位置する。隔壁１２は、格子状に形成されている。また、隔壁１２の厚みを均一にするという観点からは、図３に示すように、隔壁１２が放射状の格子として形成されることが好ましい。 The partition wall 12 is located inside the outer wall 11 in the transverse direction D of the tobacco molded body 10. The partition wall 12 is formed in a lattice shape. Further, from the viewpoint of making the thickness of the partition wall 12 uniform, the partition wall 12 is preferably formed as a radial lattice as shown in FIG.
　なお、隔壁１２の格子の形態は、これに限定されるものではない。例えば、隔壁１２の格子の形態は、隔壁１２の格子形態には、正方格子、六角格子、三角格子など、様々な形態を適用できる。 In addition, the form of the lattice of the partition wall 12 is not limited to this. For example, various forms such as a square lattice, a hexagonal lattice, and a triangular lattice can be applied to the lattice form of the partition walls 12.
　また、たばこ成形体１０の横断方向Ｄの断面では、隔壁１２は、必ずしも均一な格子となるように形成されている必要はなく、後述の厚みの範囲内であれば、偏在化した格子を含むように成形されていてもよい。従って、複数の隔壁１２によって区画される複数の貫通孔５０も、横断方向Ｄの断面において、様々な形状に形成されていてもよい。 Moreover, in the cross section of the tobacco molded body 10 in the transverse direction D, the partition wall 12 does not necessarily have to be formed to be a uniform lattice, and includes an unevenly distributed lattice as long as the thickness is within the range described later. It may be shaped like this. Accordingly, the plurality of through holes 50 defined by the plurality of partition walls 12 may also be formed in various shapes in the cross section in the transverse direction D.
　実施形態では、軸方向Ｌに直交する横断方向Ｄの断面において、外壁１１の厚さは、０．１～０．５ｍｍの範囲内である。また、軸方向Ｌに直交する横断方向Ｄにおいて、隔壁１２の厚さは、０．１～０．５ｍｍの範囲内である。上述した外壁１１の厚さと隔壁１２の厚さとは、一対の端面１０ａ、１０ｂにおいても同様の厚さである。 In the embodiment, the thickness of the outer wall 11 is in the range of 0.1 to 0.5 mm in the cross section in the transverse direction D perpendicular to the axial direction L. In the transverse direction D perpendicular to the axial direction L, the thickness of the partition wall 12 is in the range of 0.1 to 0.5 mm. The thickness of the outer wall 11 and the thickness of the partition wall 12 described above are the same in the pair of end faces 10a and 10b.
　また、実施形態では、外壁１１の厚さと隔壁１２の厚さとが、同じ場合を例に挙げて説明する。なお、外壁１１の厚さと隔壁１２の厚さとは、上述の範囲内であれば、異なるようにしてもよい。 In the embodiment, the case where the thickness of the outer wall 11 and the thickness of the partition wall 12 are the same will be described as an example. Note that the thickness of the outer wall 11 and the thickness of the partition wall 12 may be different as long as they are within the above-mentioned range.
　外壁１１の厚さと隔壁１２の厚さとが、０．１ｍｍよりも小さいと、外壁１１及び隔壁１２を成形することが困難になる。一方、外壁１１の厚さと隔壁１２の厚さとが、０．５ｍｍよりも大きいと、燃焼持続性を確保することが困難になる。 If the thickness of the outer wall 11 and the thickness of the partition wall 12 are smaller than 0.1 mm, it is difficult to mold the outer wall 11 and the partition wall 12. On the other hand, if the thickness of the outer wall 11 and the thickness of the partition wall 12 are larger than 0.5 mm, it becomes difficult to ensure the sustainability of combustion.
　なお、外壁１１の厚さ及び隔壁１２の厚さの下限値は、０．１８以上であることがより好ましい。外壁１１の厚さ及び隔壁１２の厚さの上限値は、０．２８ｍｍ以下であることがより好ましい。 In addition, it is more preferable that the lower limit value of the thickness of the outer wall 11 and the thickness of the partition wall 12 is 0.18 or more. The upper limit value of the thickness of the outer wall 11 and the thickness of the partition wall 12 is more preferably 0.28 mm or less.
　また、実施形態では、複数の隔壁１２によって区画される複数の貫通孔５０は、外壁１１の内部に形成される内部貫通孔５１と、外壁１１に開口し、溝状に形成される溝状貫通孔５２とを含む。 Further, in the embodiment, the plurality of through holes 50 defined by the plurality of partition walls 12 are the inner through holes 51 formed inside the outer wall 11 and the groove-shaped throughs formed in the outer wall 11 and formed in a groove shape. Hole 52.
　内部貫通孔５１は、横断方向Ｄの断面において、隔壁１２、又は、外壁１１と隔壁１２とが周囲に位置することによって形成される。 The internal through hole 51 is formed by the partition wall 12 or the outer wall 11 and the partition wall 12 being positioned in the periphery in the cross section in the transverse direction D.
　溝状貫通孔５２は、横断方向Ｄの断面において、隔壁１２が周囲に位置することによって形成され、外壁１１の側面において開口する。 The groove-shaped through-hole 52 is formed by the partition wall 12 being located in the periphery in the cross section in the transverse direction D, and opens on the side surface of the outer wall 11.
　なお、溝状貫通孔５２は、必ずしも設けられなくてもよい。具体的には、横断方向Ｄの断面において、外壁１１が、分断することなく全周にわたって形成されていてもよい。この場合、複数の貫通孔５０は、内部貫通孔５１によって構成される。 Note that the groove-like through hole 52 is not necessarily provided. Specifically, in the cross section in the transverse direction D, the outer wall 11 may be formed over the entire circumference without being divided. In this case, the plurality of through holes 50 are constituted by the internal through holes 51.
　たばこ成形体１０の横断方向Ｄにおける直径Ｄ１０は、５～１５ｍｍの範囲内であることが好ましい。また、たばこ成形体１０の軸方向Ｌに沿った長さＬ１０は、１～４０ｍｍの範囲内であることが好ましい。 The diameter D10 of the tobacco molded body 10 in the transverse direction D is preferably in the range of 5 to 15 mm. Further, the length L10 of the tobacco molded body 10 along the axial direction L is preferably in the range of 1 to 40 mm.
　実施形態では、横断方向Ｄの断面において、全断面積に対する複数の貫通孔５０による開口面積の割合（以下、開口率として記載）は、３０～５５％の範囲内である。なお、かかる複数の貫通孔５０には、内部貫通孔５１と溝状貫通孔５２とが含まれる。 In the embodiment, in the cross section in the transverse direction D, the ratio of the opening area by the plurality of through holes 50 to the entire cross-sectional area (hereinafter referred to as the opening ratio) is in the range of 30 to 55%. The plurality of through holes 50 include an internal through hole 51 and a groove-like through hole 52.
　また、かかる開口率は、次の式に基づいて算出できる。 Also, the aperture ratio can be calculated based on the following formula.
　開口率[%] ＝ (全断面積－外壁及び隔壁の断面積)/全断面積×１００　・・・　式（１） Opening ratio [%] = (total cross-sectional area-cross-sectional area of outer wall and partition wall) / total cross-sectional area x 100 Equation (1)
　全断面積は、直径Ｄ１０の半分を半径として、次の式に基づいて算出できる。 The total cross-sectional area can be calculated based on the following formula, with half the diameter D10 as the radius.
　全断面積　＝　半径×半径×π　　・・・　式（２） Total cross-sectional area = Radius x Radius x π ... Formula (2)
  かかる開口率が、３０％よりも小さいと、たばこ成形体１０の燃焼性を確保することが困難になり、着火性及び燃焼持続性が低下する。一方、開口率が、５５％よりも大きいと、たばこ成形体１０の燃焼によって放出される香味成分の量が低下し、香味成分による味わい（喫味）をユーザに与えにくくなる。更に、開口率が、５５％よりも大きいと、喫煙時のパフ回数が低下して、少ないパフ回数によってたばこ成形体１０が燃焼し尽くしてしまうため、ユーザに香味成分を供給する期間が短くなる恐れがある。 If the opening ratio is less than 30%, it becomes difficult to ensure the combustibility of the tobacco molded body 10, and the ignitability and combustion sustainability are reduced. On the other hand, when the opening ratio is larger than 55%, the amount of flavor components released by the burning of the tobacco molded body 10 is reduced, and it becomes difficult to give the user a taste (tasting) due to the flavor components. Furthermore, if the opening ratio is greater than 55%, the number of puffs during smoking decreases, and the tobacco molded body 10 burns out due to a small number of puffs, so the period for supplying flavor components to the user is shortened. There is a fear.
　また、かかる開口率の下限値は、４０以上であることがより好ましい。また、かかる開口率の上限値は、５０％未満であることがより好ましい。 Further, the lower limit value of the aperture ratio is more preferably 40 or more. Further, the upper limit value of the aperture ratio is more preferably less than 50%.
　また、実施形態に係るたばこ成形体１０の重量％を１００重量％とした場合、たばこ原料の重量％は、６０重量％以上である。 Moreover, when the weight percent of the tobacco molded body 10 according to the embodiment is 100 weight percent, the weight percent of the tobacco raw material is 60 weight percent or more.
　たばこ原料の量が、６０重量％よりも小さいと、たばこ成形体１０の燃焼によって放出される香味成分の量が低下し、香味成分による味わい（喫味）をユーザに与えにくくなる。 If the amount of the tobacco raw material is less than 60% by weight, the amount of the flavor component released by the burning of the tobacco molded body 10 decreases, and it becomes difficult to give the user a taste (tasting) due to the flavor component.
　また、たばこ成形体１０の見かけ密度は、１．０８ｍｇ／ｍｍ３以下である。たばこ成形体１０の見かけ密度が、１．０８ｍｇ／ｍｍ３よりも大きいと、着火性及び燃焼持続性が低下するからである。 The apparent density of the tobacco molded body 10 is 1.08 mg / mm 3 or less. This is because if the apparent density of the tobacco molded body 10 is larger than 1.08 mg / mm 3 , the ignitability and the combustion sustainability are lowered.
　なお、着火性及び燃焼持続性を向上させる観点から、たばこ成形体１０の見かけ密度の上限値は、１．０３ｍｇ／ｍｍ３以下であることが好ましく、０．９７ｍｇ／ｍｍ３以下であることがより好ましい。 From the viewpoint of improving ignitability and combustion sustainability, the upper limit of the apparent density of the tobacco molded body 10 is preferably 1.03 mg / mm 3 or less, and preferably 0.97 mg / mm 3 or less. More preferred.
　また、着火性及び燃焼持続性を向上させる観点では、たばこ成形体１０の見かけ密度は、小さいほど好ましい。 In addition, from the viewpoint of improving ignitability and combustion sustainability, the apparent density of the tobacco molded body 10 is preferably as small as possible.
　（たばこ成形体の製造方法）
　次に、実施形態に係るたばこ成形体１０の製造方法について説明する。図５は、実施形態に係るたばこ成形体１０の製造方法を示すフローチャートである。 (Method for producing tobacco molded product)
Next, the manufacturing method of the tobacco molded object 10 which concerns on embodiment is demonstrated. FIG. 5 is a flowchart showing a method for manufacturing the tobacco molded body 10 according to the embodiment.
　図５に示すように、実施形態に係る製造方法は、混合工程Ｓ１０と、押出成形工程Ｓ２０と、乾燥工程Ｓ３０とを含む。 As shown in FIG. 5, the manufacturing method according to the embodiment includes a mixing step S10, an extrusion step S20, and a drying step S30.
　混合工程Ｓ１０では、ニーダー（混練機）に、たばこ原料と、ポリオールと、バインダーと、水とを投入して、混練することによって、たばこ混合物を生成する。 In the mixing step S10, the tobacco raw material, polyol, binder, and water are put into a kneader (kneader) and kneaded to produce a tobacco mixture.
　たばこ原料には、例えば、バーレー種や黄色種等といった一般的なたばこ製品において広く用いられている原料種のたばこ原料を適用することができる。なお、たばこ原料には、これらの原料種の一つを適用してもよいし、複数を混合させたものを適用してもよい。また、たばこ原料には、たばこ粉末を適用してもよい。 Tobacco raw materials, for example, tobacco raw materials widely used in general tobacco products such as Burley and yellow can be applied. In addition, one of these raw material seeds may be applied to the tobacco raw material, or a mixture of a plurality of them may be applied. Moreover, you may apply tobacco powder to a tobacco raw material.
　たばこ混合物に含まれるたばこ原料の量は、３０重量％以上６０重量％以下の範囲内であることが好ましい。 The amount of tobacco raw material contained in the tobacco mixture is preferably in the range of 30 wt% to 60 wt%.
　かかるたばこ原料の量が、３０重量％未満であると、後述する乾燥工程Ｓ３０後、たばこ成形体１０に含まれるたばこ原料の配合割合が少なくなりすぎてしまう。この結果、たばこ成形体１０の燃焼時（喫煙時）において、香味成分の放出が少なくなり、香味成分による味わい（喫味）が低下する恐れがある。かかるたばこ原料の量が、６０重量％よりも大きいと、他の添加物の配合量（例えば、ポリオールの配合量）が少なくなりすぎてしまう。この結果、後述する押出混合物の成形性及びたばこ成形体１０の成形性の確保と、たばこ成形体１０の見かけ密度の抑制とが十分になされず、着火性及び燃焼持続性を向上させることが困難になる。 If the amount of the tobacco raw material is less than 30% by weight, the mixing ratio of the tobacco raw material contained in the tobacco molded body 10 becomes too small after the drying step S30 described later. As a result, when the tobacco molded body 10 is burned (when smoking), the release of flavor components is reduced, and the taste (tasting) of the flavor components may be reduced. When the amount of the tobacco raw material is larger than 60% by weight, the amount of other additives (for example, the amount of polyol) becomes too small. As a result, it is difficult to secure the moldability of the extrusion mixture and the moldability of the tobacco molded body 10 to be described later and to suppress the apparent density of the tobacco molded body 10 and to improve the ignitability and the combustion sustainability. become.
　ポリオールは、可塑剤としてたばこ混合物に混入される。ポリオールは、ポリプロピレングリコール（ＰＧ）であることが好ましい。ポリオールは、ポリプロピレングリコール（ＰＧ）とグリコール（Ｐ）との一方であってもよいし、両方を含んだものであってもよい。たばこ混合物に含まれるポリオールの量は、１０重量％以上３０重量％以下の範囲内である。 Polyol is mixed into the tobacco mixture as a plasticizer. The polyol is preferably polypropylene glycol (PG). The polyol may be one of polypropylene glycol (PG) and glycol (P), or may contain both. The amount of polyol contained in the tobacco mixture is in the range of 10 wt% to 30 wt%.
　かかるポリオールの量が、１０重量％未満であると、後述する押出混合物の成形性及びたばこ成形体１０の成形性の確保と、たばこ成形体１０の見かけ密度の抑制とが十分になされず、着火性及び燃焼持続性を向上させることが困難になる。かかるポリオールの量が、３０重量％よりも大きいと、ポリオールの割合が大きくなりすぎてしまい、後述する押出混合物及びたばこ成形体１０の成形性を確保することが困難になるため、着火性及び燃焼持続性を向上させることが困難になる。 When the amount of the polyol is less than 10% by weight, the molding property of the extrusion mixture and the molding property of the tobacco molded body 10 which will be described later are not sufficiently secured, and the apparent density of the tobacco molded body 10 is not sufficiently suppressed, and ignition is performed. It becomes difficult to improve the property and the sustainability of combustion. If the amount of the polyol is larger than 30% by weight, the proportion of the polyol becomes excessively large, and it becomes difficult to ensure the moldability of the extrusion mixture and the tobacco molded body 10 described later. It becomes difficult to improve sustainability.
　更に、かかるポリオールの量の下限値は、１２重量％以上であることがより好ましい。かかるポリオールの量の上限値は、２２重量％以下であることがより好ましい。 Furthermore, the lower limit of the amount of such polyol is more preferably 12% by weight or more. The upper limit of the amount of such polyol is more preferably 22% by weight or less.
　バインダーは、たばこ原料を結着させるために含まれている。バインダーは、力ルボキシメチルセルロース（ＣＭＣ）、又は、その塩であることが好ましい。また、バインダーは、力ルボキシメチルセルロースナトリウム塩であることが好ましい。バインダーは、アルギン酸でも、ペクチンでもカラギーナンでもグアーガムでもよい。 ¡Binder is included to bind tobacco materials. The binder is preferably strong ruboxymethylcellulose (CMC) or a salt thereof. Moreover, it is preferable that a binder is a strong ruboxymethylcellulose sodium salt. The binder may be alginic acid, pectin, carrageenan or guar gum.
　たばこ混合物に含まれるバインダーの量は、５重量％以下の範囲内である。かかるバインダーの量が、５重量％よりも大きいと、バインダーの量が多すぎてしまい、たばこ成形体１０の燃焼時（喫煙時）において、バインダーから放出される成分によって、たばこ原料の香味成分による味わい（喫味）が低下する恐れがある。なお、たばこ原料の配合量の割合が少なくなることによって、香味成分による味わい（喫味）が低下する恐れもある。 The amount of binder contained in the tobacco mixture is in the range of 5% by weight or less. When the amount of the binder is larger than 5% by weight, the amount of the binder is too large, and depending on the flavor component of the tobacco raw material depending on the component released from the binder when the tobacco molded body 10 is burned (when smoking). Taste (taste) may be reduced. In addition, there exists a possibility that the taste (tasting) by a flavor component may fall by the ratio of the compounding quantity of a tobacco raw material decreasing.
　更に、かかるバインダーの量の下限値は、２重量％以上であることがより好ましい。かかるバインダーの量の上限値は、４重量％以下であることがより好ましい。 Furthermore, the lower limit of the amount of the binder is more preferably 2% by weight or more. The upper limit of the amount of the binder is more preferably 4% by weight or less.
　なお、たばこ混合物には、アルカリ金属塩又はアルカリ土類金属塩が含まれていてもよい。アルカリ金属塩又はアルカリ土類金属塩が含まれる場合、たばこ成形体１０の外壁１１及び隔壁１２の強度を高めるとともに、たばこ成形体１０の燃焼持続性を高めることができる。なお、たばこ混合物には、アルカリ金属塩とアルカリ土類金属塩とが必ずしも含まれていなくてもよい。なお、たばこ混合物にアルカリ土類金属塩を含める場合、アルカリ土類金属塩は、炭酸カルシウムであることが好ましい。 The tobacco mixture may contain an alkali metal salt or an alkaline earth metal salt. When an alkali metal salt or an alkaline earth metal salt is included, the strength of the outer wall 11 and the partition wall 12 of the tobacco molded body 10 can be increased, and the combustion sustainability of the tobacco molded body 10 can be increased. The tobacco mixture does not necessarily include an alkali metal salt and an alkaline earth metal salt. In addition, when an alkaline earth metal salt is included in the tobacco mixture, the alkaline earth metal salt is preferably calcium carbonate.
　また、アルカリ金属塩（又はアルカリ土類金属塩）をたばこ混合物に含める場合、アルカリ金属塩（又はアルカリ土類金属塩）の量は、１０重量％以上３０重量％以下の範囲内であることが好ましい。かかるアルカリ金属塩（又はアルカリ土類金属塩）の量が、１０重量％未満であると、外壁１１及び隔壁１２の強度を高める効果や、たばこ成形体１０の燃焼持続性を高める効果が十分に得られない。アルカリ金属塩（又はアルカリ土類金属塩）の量が、３０重量％よりも大きいと、たばこ原料の配合量の割合が少なくなってしまう。この結果、たばこ成形体１０の燃焼時（喫煙時）において、香味成分の放出が少なくなり、香味成分による味わい（喫味）が低下する恐れがある。 In addition, when an alkali metal salt (or alkaline earth metal salt) is included in the tobacco mixture, the amount of the alkali metal salt (or alkaline earth metal salt) may be in the range of 10 wt% to 30 wt%. preferable. When the amount of the alkali metal salt (or alkaline earth metal salt) is less than 10% by weight, the effect of increasing the strength of the outer wall 11 and the partition wall 12 and the effect of increasing the combustion sustainability of the tobacco molded body 10 are sufficiently obtained. I can't get it. When the amount of the alkali metal salt (or alkaline earth metal salt) is larger than 30% by weight, the proportion of the tobacco raw material is reduced. As a result, when the tobacco molded body 10 is burned (when smoking), the release of flavor components is reduced, and the taste (tasting) of the flavor components may be reduced.
　押出成形工程Ｓ２０では、たばこ原料と、ポリオールと、バインダーと、水とを含むたばこ混合物を押し出し成形することによって、押出混合物を生成する。具体的に、押出成形機(宮崎鉄工社製，混練・真空押出成形機 FM-P20)を用いて、混合工程Ｓ１０によって生成されたたばこ混合物を、押出成形して押出成形物を生成する。 In the extrusion molding step S20, an extrusion mixture is generated by extruding a tobacco mixture containing a tobacco raw material, a polyol, a binder, and water. Specifically, the tobacco mixture produced in the mixing step S10 is extruded using an extruder (Miyazaki Tekko Co., Ltd., kneading / vacuum extruder FM-P20) to produce an extruded product.
　かかる押出成形物は、図２乃至図４に示すたばこ成形体１０のように、外壁１１及び隔壁１２を有する形状に形成されている。なお、押出成形工程Ｓ２０では、軸方向Ｌの長さがたばこ成形体１０と同等の押出成形物を生成してもよいし、軸方向Ｌの長さがたばこ成形体１０よりも長い長さのものを、押出成形物として生成してもよい。 Such an extrudate is formed into a shape having an outer wall 11 and a partition wall 12 like a tobacco molded body 10 shown in FIGS. In the extrusion molding step S <b> 20, an extruded product having an axial length L that is equivalent to that of the tobacco molded product 10 may be generated, or the axial length L may be longer than that of the tobacco molded product 10. Things may be produced as extrudates.
　なお、押出成形工程Ｓ２０では、押出圧力を３～５ＭＰａとし、冷却温度を約１０℃とした条件に基づいて、たばこ混合物を押出成形して、押出成形物を生成してもよい。 In the extrusion molding step S20, the tobacco mixture may be extruded to produce an extruded product based on the conditions where the extrusion pressure is 3 to 5 MPa and the cooling temperature is about 10 ° C.
　乾燥工程Ｓ３０では、押出混合物を乾燥させることによって、たばこ成形体１０を生成する。具体的に、乾燥工程Ｓ３０において、押出混合物を乾燥させるための温度は、４０℃以上１００℃未満であることが好ましい。 In the drying step S30, the tobacco mixture 10 is generated by drying the extruded mixture. Specifically, in the drying step S30, the temperature for drying the extruded mixture is preferably 40 ° C. or higher and lower than 100 ° C.
　なお、乾燥工程Ｓ３０では、恒温乾燥機を用いて、押出混合物を乾燥させてもよいし、減圧乾燥機を用いて、押出混合物を乾燥させてもよい。また、押出混合物を乾燥させる期間は、水の除去に加え、ポリオールを除去することができれば、特に限定されない。例えば、押出混合物を乾燥させる期間は、数時間でもよいし、数日でもよいし、２週間でもよい。 In the drying step S30, the extrusion mixture may be dried using a constant temperature dryer, or the extrusion mixture may be dried using a vacuum dryer. Further, the period for drying the extruded mixture is not particularly limited as long as the polyol can be removed in addition to the removal of water. For example, the period for drying the extruded mixture may be several hours, several days, or two weeks.
　なお、乾燥工程Ｓ３０では、たばこ成形体１０よりも長い押出混合物を乾燥させてもよい。例えば、乾燥工程Ｓ３０では、たばこ成形体１０の長さＬ１０の複数個分の長さを有する押出混合物を乾燥させた後、複数のたばこ成形体１０の長さを有するたばこ成形体１０の連続体を生成する。そして、かかるたばこ成形体１０の連続体を軸方向Ｌにおいて、所望の長さに切断して、個別のたばこ成形体１０を生成してもよい。 In the drying step S30, an extruded mixture longer than the tobacco molded body 10 may be dried. For example, in the drying step S30, after the extruded mixture having a length corresponding to a plurality of lengths L10 of the tobacco molded body 10 is dried, a continuous body of tobacco molded bodies 10 having the length of the plurality of tobacco molded bodies 10 is obtained. Is generated. And the continuous body of the tobacco molded body 10 may be cut into a desired length in the axial direction L to generate individual tobacco molded bodies 10.
　（作用及び効果）
　実施形態に係るたばこ成形体１０は、軸方向Ｌに対向する一対の端面１０ａ、１０ｂと、軸方向Ｌに延びる筒状の外壁１１と、外壁１１の内部において、一対の端面１０ａ、１０ｂ間を貫通する複数の貫通孔５０を区画する隔壁１２とを有する。 (Function and effect)
The tobacco molded body 10 according to the embodiment includes a pair of end surfaces 10 a and 10 b facing in the axial direction L, a cylindrical outer wall 11 extending in the axial direction L, and a space between the pair of end surfaces 10 a and 10 b inside the outer wall 11. And a partition wall 12 defining a plurality of through holes 50 penetrating therethrough.
　たばこ成形体１０では、軸方向Ｌに直交する横断方向Ｄの断面において、外壁１１の厚さは、０．１～０．５ｍｍの範囲内である。また、軸方向Ｌに直交する横断方向Ｄにおいて、隔壁１２の厚さは、０．１～０．５ｍｍの範囲内である。また、たばこ成形体１０では、横断方向Ｄの断面において、全断面積に対する複数の貫通孔５０による開口率は、３０～５５％の範囲内である。また、たばこ原料の重量％は、６０重量％以上であり、たばこ成形体１０の見かけ密度は、１．０８ｍｇ／ｍｍ３以下である。 In the tobacco molded body 10, the thickness of the outer wall 11 is in the range of 0.1 to 0.5 mm in the cross section in the transverse direction D perpendicular to the axial direction L. In the transverse direction D perpendicular to the axial direction L, the thickness of the partition wall 12 is in the range of 0.1 to 0.5 mm. Further, in the tobacco molded body 10, in the cross section in the transverse direction D, the opening ratio by the plurality of through holes 50 with respect to the entire cross-sectional area is in the range of 30 to 55%. Further, the weight percent of the tobacco raw material is 60% by weight or more, and the apparent density of the tobacco molded body 10 is 1.08 mg / mm 3 or less.
　かかる構成によれば、たばこ成形体１０の断面において、外壁１１と隔壁１２とが形成されているため、単に、外壁１１のみを薄くしたたばこ成形体１０を形成する場合に比べて、燃焼面積が増加する。かかるたばこ成形体１０によれば、燃焼するたばこ成形体１０から放出される香味成分を十分に確保できる。すなわち、ユーザに与えられる香味成分による味わい（喫味）を十分に確保できる。 According to such a configuration, since the outer wall 11 and the partition wall 12 are formed in the cross section of the tobacco molded body 10, the combustion area is simply compared to the case where the tobacco molded body 10 in which only the outer wall 11 is thinned is formed. To increase. According to the tobacco molded body 10, the flavor component released from the burning tobacco molded body 10 can be sufficiently secured. That is, it is possible to sufficiently ensure the taste (tasting) by the flavor component given to the user.
　また、かかる構成によれば、外壁１１及び隔壁１２の厚みと、たばこ原料の重量％と、たばこ成形体１０の見かけ密度とを、上述のように規定することによって、たばこ成形体１０の着火性及び燃焼持続性を向上させることができる。 Moreover, according to this structure, the ignitability of the tobacco molded body 10 is defined by defining the thickness of the outer wall 11 and the partition wall 12, the weight percent of the tobacco raw material, and the apparent density of the tobacco molded body 10 as described above. In addition, combustion sustainability can be improved.
　以上のように、実施形態に係るたばこ成形体１０によれば、ユーザに与えられる香味成分による味わいを確保しつつ、着火性及び燃焼持続性を向上させることができる。 As described above, according to the tobacco molded body 10 according to the embodiment, it is possible to improve the ignitability and the combustion sustainability while ensuring the taste due to the flavor component given to the user.
　また、実施形態に係るたばこ成形体１０では、複数の隔壁１２によって区画される複数の貫通孔５０は、外壁１１の内部に形成される内部貫通孔５１と、外壁１１に開口し、溝状に形成される溝状貫通孔５２とを含む。 Further, in the tobacco molded body 10 according to the embodiment, the plurality of through holes 50 partitioned by the plurality of partition walls 12 open to the inner through hole 51 formed in the outer wall 11 and the outer wall 11, and form a groove shape. And a groove-like through hole 52 to be formed.
　かかるたばこ成形体１０では、外壁１１に開口し、溝状に形成される溝状貫通孔５２が形成されているため、外壁１１の側面に角部が形成される。これにより、たばこ成形体１０をつかみ易くなり、たばこ成形体１０をホルダ２０に装着しやすくなる。特に、実施形態に係る香味吸引具１では、ユーザがたばこ成形体１０を何度もホルダ２０に装着する利用形態であるため、たばこ成形体１０をホルダ２０に装着する際の作業性を高めることができる。 In the tobacco molded body 10, since the groove-like through hole 52 that opens to the outer wall 11 and is formed in a groove shape is formed, a corner is formed on the side surface of the outer wall 11. Thereby, it becomes easy to grasp the tobacco molded body 10, and it becomes easy to attach the tobacco molded body 10 to the holder 20. In particular, in the flavor suction tool 1 according to the embodiment, since the user uses the cigarette molded body 10 on the holder 20 many times, the workability when the cigarette molded body 10 is mounted on the holder 20 is improved. Can do.
　実施形態に係るたばこ成形体１０の製造方法では、たばこ原料と、ポリオールと、バインダーと、水とを含むたばこ混合物を押し出し成形することによって、押出混合物を生成する押出成形工程Ｓ２０と、押出混合物を乾燥させることによって、たばこ成形体１０を生成する乾燥工程Ｓ３０とを含む。 In the method for producing the tobacco molded body 10 according to the embodiment, an extrusion molding step S20 that generates an extrusion mixture by extruding a tobacco mixture containing a tobacco raw material, a polyol, a binder, and water, and an extrusion mixture. A drying step S30 for producing the tobacco molded body 10 by drying.
　たばこ成形体１０の製造方法では、たばこ混合物の全体重量％を１００重量％とした場合、ポリオールの重量％は、１０～３０重量％の範囲内であり、バインダーの重量％は、５重量％以下の範囲内であり、水の重量％は、２０～３５重量％の範囲内である。 In the method for producing the tobacco molded body 10, when the total weight% of the tobacco mixture is 100% by weight, the weight% of the polyol is in the range of 10 to 30% by weight, and the weight% of the binder is 5% by weight or less. And the weight percent of water is in the range of 20 to 35 weight percent.
　かかる製造方法によれば、たばこ成形体１０において、外壁１１及び隔壁１２の成形性が高まる。よって、かかる製造方法によれば、着火性及び燃焼持続性を向上させたたばこ成形体１０を製造できる。 According to this manufacturing method, the moldability of the outer wall 11 and the partition wall 12 in the tobacco molded body 10 is enhanced. Therefore, according to this manufacturing method, the tobacco molded body 10 with improved ignitability and combustion sustainability can be manufactured.
　ここで、従来技術では、たばこ混合物において、水より蒸発しやすい有機液体及び水、又は、スターチ及び水が含まれており、かかるたばこ混合物を押出成形した後に、加熱乾燥させる方法が用いられている。 Here, in the prior art, the tobacco mixture contains an organic liquid and water that easily evaporate from water, or starch and water, and a method of heating and drying the tobacco mixture after extrusion is used. .
　実施形態に係るたばこ混合物には、水より蒸発しやすい有機液体に替えて、ポリオールが含まれている。ポリオールは、水に比べて、気化し難いという性質を有する。したがって、乾燥工程Ｓ３０において、たばこ混合物を成形した押出混合物を乾燥する際に、押出混合物からの水の除去と、押出混合物からのポリオールの除去との２段階で除去が順になされる。従って、乾燥工程Ｓ３０では、水の除去によって、押出成形体のたばこ成形体１０としての形状が担保された上で、その後、押出成形体の内部に残存するポリオールが除去されるため、たばこ成形体１０の見かけ密度が低下する。これにより、たばこ成形体１０の着火性及び燃焼持続性の向上が図られる。すなわち、実施形態に係る製造方法では、たばこ成形体１０の成形性の向上と、見かけ密度の抑制とを両立することができる。 The tobacco mixture according to the embodiment contains a polyol instead of an organic liquid that is more easily evaporated than water. Polyol has the property that it is less likely to vaporize than water. Therefore, in the drying step S30, when drying the extruded mixture formed from the tobacco mixture, the removal is sequentially performed in two stages, that is, removal of water from the extruded mixture and removal of polyol from the extruded mixture. Therefore, in the drying step S30, the removal of water secures the shape of the extruded molded body as the tobacco molded body 10 and then the polyol remaining in the extruded molded body is removed. The apparent density of 10 is reduced. Thereby, the ignitability and combustion sustainability of the tobacco molded body 10 are improved. That is, in the manufacturing method according to the embodiment, it is possible to achieve both improvement in moldability of the tobacco molded body 10 and suppression of the apparent density.
　また、実施形態に係る製造方法では、たばこ混合物には、スターチが含まれていないことが好ましい。かかる製造方法によれば、スターチによって水が吸水されることによって、たばこ混合物がゼラチン化することを抑制できる。これにより、たばこ混合物を成形した押出混合物を乾燥する乾燥工程Ｓ３０において、水の蒸発に起因した独立気泡の発生により、外壁１１及び隔壁１２が変形してしまうことを抑制できる。すなわち、かかる製造方法によれば、外壁１１の厚さ及び隔壁１２の厚さをより薄く成形できるため、着火性及び燃焼持続性を向上させたたばこ成形体１０を製造できる。 Moreover, in the manufacturing method according to the embodiment, it is preferable that the tobacco mixture does not contain starch. According to this manufacturing method, gelatinization of the tobacco mixture can be suppressed by absorbing water by the starch. Thereby, in drying process S30 which drys the extrusion mixture which shape | molded the tobacco mixture, it can suppress that the outer wall 11 and the partition 12 deform | transform by generation | occurrence | production of the independent bubble resulting from water evaporation. That is, according to this manufacturing method, since the thickness of the outer wall 11 and the thickness of the partition wall 12 can be formed thinner, the tobacco molded body 10 with improved ignitability and combustion sustainability can be manufactured.
　また、たばこ混合物には、カーボンが含まれていないことが好ましい。すなわち、たばこ成形体１０にカーボンが含まれないため、燃焼するたばこ成形体１０から放出される香味成分による味わい（喫味）の低下を抑制できる。 Moreover, it is preferable that the tobacco mixture does not contain carbon. That is, since carbon is not contained in the tobacco molded body 10, it is possible to suppress a decrease in taste (tasting) due to flavor components released from the burning tobacco molded body 10.
