For example, the heating unit 121 is configured in a film shape and arranged to cover the outer periphery of the holding unit 140. When the heating unit 121 generates heat, the aerosol source 11 included in the flavor inhalation article 1 is heated from the outer periphery of the flavor inhalation article 1. The heating unit 121 generates heat when power is supplied from the power supply unit 111. As an example, power may be supplied when the sensor unit 112 detects that a predetermined user input has been made. When the temperature of the flavor inhalation article 1 heated by the heating unit 121 reaches a predetermined temperature, the user can inhale. Thereafter, when the sensor unit 112 detects that a predetermined user input has been made, power supply may be stopped. As another example, power may be supplied and aerosol may be generated during a period in which the sensor unit 112 detects that the user has inhaled.
 断熱部144は、少なくとも加熱部121の外周を覆うように配置される。例えば、断熱部144は、真空断熱材、及びエアロゲル断熱材等により構成される。なお、真空断熱材とは、例えば、グラスウール及びシリカ(ケイ素の粉体)等を樹脂製のフィルムで包んで高真空状態にすることで、気体による熱伝導を限りなくゼロに近づけた断熱材である。 The insulating section 144 is arranged so as to cover at least the outer periphery of the heating section 121. For example, the insulating section 144 is made of a vacuum insulating material, an aerogel insulating material, or the like. Note that a vacuum insulating material is an insulating material in which, for example, glass wool and silica (silicon powder) are wrapped in a resin film and placed in a high vacuum state, thereby reducing the thermal conduction of gas to as close to zero as possible.

The adhesive may include a hot melt adhesive, and the hot melt adhesive may further include polyvinyl alcohol. In addition, when the filter portion 30 is composed of two or more members, it is preferable that the wrapping paper is wound around each of these two or more members, and then wrapped with another wrapping paper.

The airflow resistance is measured according to the ISO standard method (ISO6565) using, for example, a filter airflow resistance measuring device manufactured by Cerulean Co., Ltd. The airflow resistance of the filter unit 30 refers to the air pressure difference between the first side and the second side when air is allowed to flow at a predetermined air flow rate (17.5 cc/min) from the first side to the second side in a state in which air does not pass through the sides of the filter unit 30. The unit is generally expressed in mmH2O .
 フィルタ31は、いわゆるペーパーフィルタであり、ユーザによる香味吸引物品1の吸引時にフィルタ31内をエアロゾルが中心線方向に通過することが可能なチャンネルとして空隙31bが形成されたペーパーフィルタである。例えば、フィルタ31は、シート部材31aを充填して成形したペーパーフィルタである。具体的には、フィルタ31には、中心線方向に延びるエアロゾルの通過経路を確保するようにシート部材31aを充填して成形したペーパーフィルタである。
 フィルタ31を構成するシート部材31aの充填密度は、特段制限されないが、通常90mg/cm以上720mg/cm以下である。図5の領域302に示すように、物体33が配置されていない領域302のシート部材31aの充填密度は、90mg/cm以上360mg/cm以下であることが好ましく、150mg/cm以上240mg/cm以下であることがより好ましい。また、図5の領域301に示すように、物体33が配置されている領域301のシート部材31aの充填密度は、105mg/cm以上720mg/cm以下であることが好ましく、170mg/cm以上480mg/cm以下であることがより好ましい。
The filter 31 is a so-called paper filter, and is a paper filter in which a gap 31b is formed as a channel through which an aerosol can pass in the center line direction inside the filter 31 when a user inhales the flavor inhalation article 1. For example, the filter 31 is a paper filter formed by filling with a sheet member 31a. Specifically, the filter 31 is a paper filter formed by filling with the sheet member 31a so as to secure a passage path for the aerosol extending in the center line direction.
The packing density of the sheet member 31a constituting the filter 31 is not particularly limited, but is usually 90 mg/cm 3 or more and 720 mg/cm 3 or less. As shown in region 302 in Fig. 5, the packing density of the sheet member 31a in the region 302 where the object 33 is not placed is preferably 90 mg/cm 3 or more and 360 mg/cm 3 or less, and more preferably 150 mg/cm 3 or more and 240 mg/cm 3 or less. As shown in region 301 in Fig. 5, the packing density of the sheet member 31a in the region 301 where the object 33 is placed is preferably 105 mg/cm 3 or more and 720 mg/cm 3 or less, and more preferably 170 mg/cm 3 or more and 480 mg/cm 3 or less.
 フィルタ31を構成するシート部材31aの材質は、フィルタの一般的な機能を実現することが可能であれば特に制限されないが、パルプが主成分であるパルプ紙等の紙又は不織布であることが好ましく、紙がより好ましい。その他、フィルタ31を構成するシート部材31aの材質に、例えばポリマーシート、金属シート等が使用されてもよい。なお、フィルタ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、エアロゾル源11の充填率が低くなる傾向のある非燃焼加熱型の香味吸引物品1においては、ろ過機能を抑えつつ香味吸引物品1内に含まれる部材の脱落を防止する、ということも重要な機能の一つである。
 シート部材31a自体の密度はフィルタの一般的な機能を実現する観点から0.05g/cm以上が好ましく、より好ましくは0.5g/cm以上である。また、シート部材31aの厚さは、下限は0.03mm以上が好ましく、より好ましくは0.05mm以上であり、上限は1.20mm以下が好ましく、より好ましくは0.5mm以下である。
The material of the sheet member 31a constituting the filter 31 is not particularly limited as long as it can realize the general function of the filter, but is preferably paper or nonwoven fabric such as pulp paper mainly composed of pulp, and more preferably paper. In addition, for example, a polymer sheet, a metal sheet, etc. may be used as the material of the sheet member 31a constituting the filter 31. In addition, the general function of the filter includes, for example, adjusting the amount of air mixed when inhaling the aerosol, reducing flavor, reducing nicotine and tar, etc., but it is not necessary to have all of these functions. In addition, in the non-combustion heating type flavor inhalation article 1, which tends to generate fewer components and has a lower filling rate of the aerosol source 11 compared to cigarette products, one of the important functions is to suppress the filtering function while preventing the components contained in the flavor inhalation article 1 from falling off.
From the viewpoint of realizing the general function of the filter, the density of the sheet member 31a itself is preferably 0.05 g/ cm3 or more, and more preferably 0.5 g/ cm3 or more. The lower limit of the thickness of the sheet member 31a is preferably 0.03 mm or more, and more preferably 0.05 mm or more, and the upper limit is preferably 1.20 mm or less, and more preferably 0.5 mm or less.
 本実施形態の場合、フィルタ31は、折り畳まれたり、しわやギャザー等が付けられたりしたシート部材31aによって形成され、中心線方向に延びるエアロゾルの通過経路を確保するように充填されている。具体的には、フィルタ31は、図3(A)に示すように、フィルタ部30の長手方向に渡って空隙31bが形成されるようにシート部材31aが充填されたペーパーフィルタであって、シート部材31aがギャザーされたペーパーフィルタである。ここで、「ギャザーされた」とは、シート部材31aがフィルタ31の中心線方向と水平に複数回折り返された状態で充填されたことである。
 フィルタ31を構成するシート部材31aは、1枚であってもよく、2枚以上であってもよい。また、折り畳み又はひだはなくてもよく、中心線方向に延びるエアロゾルの通過経路が確保されていればよい。具体的には、フィルタ31は、図4(A)に示すように、短冊状のシート部材31aが充填されたペーパーフィルタでもよい。
 シート部材31aは全体に捲縮処理することにより、シート部材31aに効率よく空隙31bを形成することができる。捲縮処理とはシート部材31aにしわを設ける処理である。例えば、表面に複数の凸部を有する一対のローラ間に処理対象のシート部材31aを通すことによって、当該シート部材31aの表面と裏面の両方にシート部材31aの搬送方向に直交して延びるしわを設けて捲縮処理を施すことができる。
In this embodiment, the filter 31 is formed of a sheet member 31a that is folded, wrinkled, gathered, or the like, and is filled so as to ensure a passage path for the aerosol extending in the center line direction. Specifically, as shown in Fig. 3(A), the filter 31 is a paper filter in which the sheet member 31a is filled so as to form a gap 31b along the longitudinal direction of the filter part 30, and the sheet member 31a is gathered. Here, "gathered" means that the sheet member 31a is filled in a state where it is folded back multiple times horizontally to the center line direction of the filter 31.
The sheet member 31a constituting the filter 31 may be one sheet or two or more sheets. In addition, the filter 31 does not need to be folded or pleated, as long as a passage for the aerosol extending in the center line direction is secured. Specifically, the filter 31 may be a paper filter filled with rectangular sheet members 31a as shown in FIG. 4(A).
The sheet member 31a is entirely crimped, so that the gaps 31b can be efficiently formed in the sheet member 31a. The crimping process is a process for forming wrinkles in the sheet member 31a. For example, the sheet member 31a to be treated is passed between a pair of rollers having a plurality of protrusions on the surface, so that the sheet member 31a can be crimped by forming wrinkles on both the front and back surfaces of the sheet member 31a that extend perpendicular to the conveying direction of the sheet member 31a.
 物体33は、フィルタ31内に配置され、フィルタ31内の流路を変更すると共に、通過するエアロゾルに対するろ過機能をフィルタ31よりも抑えた部材である。本実施形態ではペーパーフィルタを使用するが、ペーパーフィルタは、酢酸セルロース等の繊維を用いたフィルタよりも一般的に柔らかいため、フィルタ部30全体が酢酸セルロース等の繊維を使用した場合よりも柔らかくなる。物体33は、ペーパーフィルタが用いられることに起因してフィルタ部30全体が柔らかくならないようにするため、物体33が配置されていない位置のフィルタ31よりも硬い部材を用いる。物体33の使用により、フィルタ部30の所望の位置に所望の硬さを付与することが可能となり、香味吸引物品の咥え心地や手ごたえを向上させ、更に香味吸引物品が非燃焼加熱型である場合に吸引装置へ香味吸引物品を差し込み装着する際の作業性を向上させることが可能となる。
 物体33は、1つであってもよく、2つ以上であってもよい。具体的には、図3(B)に示すように、1つの物体33がフィルタ31内に配置されてもよく、図4(B)に示すように、複数の物体33がフィルタ31内に配置されてもよい。
The object 33 is a member disposed in the filter 31, which changes the flow path in the filter 31 and has a lower filtering function for the aerosol passing therethrough than the filter 31. In this embodiment, a paper filter is used, but since a paper filter is generally softer than a filter using fibers such as cellulose acetate, the entire filter unit 30 is softer than when fibers such as cellulose acetate are used. The object 33 is a member harder than the filter 31 at a position where the object 33 is not disposed, so that the entire filter unit 30 does not become soft due to the use of a paper filter. The use of the object 33 makes it possible to impart a desired hardness to a desired position of the filter unit 30, improving the bite comfort and response of the flavor suction article, and further improving the workability when inserting and attaching the flavor suction article to the suction device when the flavor suction article is a non-combustion heating type.
The number of objects 33 may be one or more. Specifically, as shown in Fig. 3B, one object 33 may be disposed in the filter 31, or as shown in Fig. 4B, a plurality of objects 33 may be disposed in the filter 31.
 物体33の横断面において、その外周の形状は、フィルタ部30の形状に合わせて適宜変更し得る。外周の形状の典型例としては円が挙げられるが、例えば楕円、多角、角丸多角等も可能である。
 また、横断面において、フィルタ部30の面積に対する物体33の面積の割合は、特段制限されないが、15%以上50%以下を挙げることができ、20%以上40%以下が好ましい。なお、複数の物体33がフィルタ31内に配置されている場合には、1つの横断面における、フィルタ部30の面積に対する複数の物体33の面積の合計の割合が上記の範囲内であることが好ましい。また、図1に示す様に、物体33が中心線方向の両端が開口した中空部材である場合は、前記した面積の割合において、物体33の面積には中空部材の内部も含む。
 物体33の横断面において、その外周の形状が実質的に円形である場合、その円周は、製品のサイズに合わせて適宜変更し得るが、通常6mm以上15mm以下であり、9mm以上11mm以下であることがより好ましい。また、フィルタ31の円周に対する物体33の円周の比率は、通常0.20以上0.70未満であり、0.35以上0.50以下であることがより好ましい。なお、横断面が円形でない場合、上記の円周は、その断面の面積と同じ面積を有する円で仮定し、その円における円周が適用される。
In the cross section of the object 33, the shape of the outer periphery can be appropriately changed in accordance with the shape of the filter portion 30. A typical example of the outer periphery shape is a circle, but other shapes such as an ellipse, a polygon, or a polygon with rounded corners are also possible.
In addition, in the cross section, the ratio of the area of the object 33 to the area of the filter portion 30 is not particularly limited, but may be 15% or more and 50% or less, and preferably 20% or more and 40% or less. When a plurality of objects 33 are disposed in the filter 31, it is preferable that the ratio of the total area of the plurality of objects 33 to the area of the filter portion 30 in one cross section is within the above range. In addition, as shown in Fig. 1, when the object 33 is a hollow member having both ends in the center line direction open, the area of the object 33 in the above-mentioned area ratio includes the inside of the hollow member.
When the cross section of the object 33 has a substantially circular outer periphery, the circumference can be changed as appropriate according to the size of the product, but is usually 6 mm or more and 15 mm or less, and more preferably 9 mm or more and 11 mm or less. The ratio of the circumference of the object 33 to the circumference of the filter 31 is usually 0.20 or more and less than 0.70, and more preferably 0.35 or more and 0.50 or less. When the cross section is not circular, the circumference is assumed to be a circle having the same area as the cross section, and the circumference of that circle is applied.
 換言すると、物体33のフィルタ部30の長手方向に沿う長さは、フィルタ31のフィルタ部30の長手方向に沿う長さよりも長くないことが好ましい。物体33は、フィルタ部30の長手方向にそって配置されている。
 また、物体33の中心線方向の大きさがフィルタ31の中心線方向の大きさよりも小さい場合、物体33の中心線方向の大きさとフィルタ31の中心線方向の大きさとの差は、2mm以上であることが好ましい。中心線方向において、物体33の大きさをフィルタ31の大きさよりも小さくすることで、物体33がフィルタ31の少なくとも一方の端面から突出せず、物体33を有さない香味吸引物品に使用されるフィルタ31の端面と同様の外観にすることができる。中心線方向において、物体33をフィルタ31よりも2mm以上小さくすることで、フィルタ31の少なくとも一端から物体33が見えないようにすることができる。
In other words, it is preferable that the length of the object 33 along the longitudinal direction of the filter portion 30 is not longer than the length of the filter 31 along the longitudinal direction of the filter portion 30. The object 33 is disposed along the longitudinal direction of the filter portion 30.
Furthermore, when the size of the object 33 in the center line direction is smaller than the size of the filter 31 in the center line direction, the difference between the size of the object 33 in the center line direction and the size of the filter 31 in the center line direction is preferably 2 mm or more. By making the size of the object 33 smaller than the size of the filter 31 in the center line direction, the object 33 does not protrude from at least one end face of the filter 31, and the appearance can be made similar to that of the end face of the filter 31 used in a flavor inhalation article that does not have the object 33. By making the object 33 2 mm or more smaller than the filter 31 in the center line direction, the object 33 can be made invisible from at least one end of the filter 31.
 物体33は、横断面が中空である中空部材であり、中心線方向の少なくとも一端が開口した中空部材であることが好ましく、中心線方向の両端が開口した中空部材であることがより好ましい。また、物体33を中心線方向の両端が開口した中空部材とすることで、中心線方向の一端が閉口した部材に比べて、通過するエアロゾルに対するろ過機能を抑えて香喫味のデリバリー効率を向上させることができる。
 物体33が中心線方向の両端が開口した中空部材である場合、物体33内を通過するエアロゾルを全くろ過しない。また、フィルタ31のろ過率よりも低いろ過率には、ろ過率「0%」も含まれる。なお、物体33が中心線方向の両端が開口した中空部材である場合に、フィルタ31内を通過するエアロゾルの流路は物体33内又はフィルタ31内に限られるため、この場合も、物体33はフィルタ31内のエアロゾルの流路を変更することができると考えられる。
The object 33 is a hollow member having a hollow cross section, and is preferably a hollow member having at least one end in the center line direction open, and more preferably a hollow member having both ends in the center line direction open. Furthermore, by making the object 33 a hollow member having both ends in the center line direction open, the filtering function for the aerosol passing through can be suppressed and the delivery efficiency of the smoking flavor can be improved compared to a member having one end in the center line direction closed.
When the object 33 is a hollow member with both ends open in the center line direction, it does not filter at all the aerosol passing through the object 33. In addition, a filtration rate lower than the filtration rate of the filter 31 also includes a filtration rate of "0%". Note that when the object 33 is a hollow member with both ends open in the center line direction, the flow path of the aerosol passing through the filter 31 is limited to within the object 33 or within the filter 31, so in this case too, it is considered that the object 33 can change the flow path of the aerosol in the filter 31.
 ここで、物体33の構成の具体例を説明する。
 例えば、物体33は、フィルタ31を構成するシート部材31aと同様の材質を含むシート部材31aが巻かれることで円筒等の横断面が中空となるように成形された管である。具体的には、物体33は、紙が巻かれることで成形された紙管である。物体33を紙管とすることで、物体33を構成する材料を、フィルタ31と略同一とすることができる。
Here, a specific example of the configuration of the object 33 will be described.
For example, the object 33 is a tube formed by winding a sheet member 31a containing the same material as the sheet member 31a constituting the filter 31 so as to have a hollow cross section, such as a cylinder. Specifically, the object 33 is a paper tube formed by winding paper. By making the object 33 a paper tube, the material constituting the object 33 can be substantially the same as that of the filter 31.
 物体33は、少なくとも紙を含む複数のシート部材31aが互いに貼り合わせられ、かつ、らせん状に巻きつけられて成形された紙管、いわゆるスパイラル紙管である。スパイラル紙管の製法では、横断面が円形の紙管を容易に成形することが可能である。物体33にスパイラル紙管を採用することで、フィルタ部30の面積に対する物体33の面積の割合を抑えつつ、物体33の強度を向上させることができる。また、香料成分や、香味成分、たばこ粉砕物等を含むシート部材31aを紙と組み合わせて貼り合わせることで、エアロゾルに新たな香喫味を付与することができる。 The object 33 is a so-called spiral paper tube, which is a paper tube formed by bonding together a plurality of sheet members 31a including at least paper and winding them in a spiral shape. The spiral paper tube manufacturing method makes it possible to easily form a paper tube with a circular cross section. By using a spiral paper tube for the object 33, the strength of the object 33 can be improved while suppressing the ratio of the area of the object 33 to the area of the filter section 30. In addition, by combining and bonding the sheet members 31a including fragrance components, flavor components, tobacco powder, etc. with paper, a new flavor and aroma can be imparted to the aerosol.
 その他、物体33は、紙が何重にも円筒状に巻かれて成形された紙管、いわゆるストレート紙管であってもよい。ストレート紙管の製法では、スパイラル紙管の製法に比べて、紙の貼り付けに使用される糊の量を少なくすることができる。
 また、物体33は、少なくとも紙を含む複数のシート部材31aが積層されて成形された紙管であってもよい。複数のシート部材31aが積層されることで、シート部材31aの各々の坪量が小さい場合にも物体33の強度を維持させることができる。
 なお、物体33は、紙が巻かれることで成形された紙管に限られず、既に横断面が中空である合成樹脂等の管により成形されてもよい。物体33の管である場合、この管の肉厚の厚さは、特段制限されず、通常50μm以上500μm以下であり、100μm以上250μm以下であることが好ましい。例えば、シート部材31aが重なる場合、重なったシート部材31aの厚さの合計が、上記の範囲内であればよい。管の肉厚の厚さを上記の範囲とすることで、フィルタ31等の外部からの圧力による物体33の変形を抑制することができる。
Alternatively, the object 33 may be a paper tube formed by winding paper multiple times into a cylindrical shape, a so-called straight paper tube. In the manufacturing method of a straight paper tube, the amount of glue used to attach the paper can be reduced compared to the manufacturing method of a spiral paper tube.
Furthermore, the object 33 may be a paper tube formed by stacking a plurality of sheet members 31a including at least paper. By stacking a plurality of sheet members 31a, the strength of the object 33 can be maintained even when the basis weight of each of the sheet members 31a is small.
The object 33 is not limited to a paper tube formed by winding paper, but may be formed from a tube of synthetic resin or the like that already has a hollow cross section. When the object 33 is a tube, the wall thickness of the tube is not particularly limited, and is usually 50 μm or more and 500 μm or less, and preferably 100 μm or more and 250 μm or less. For example, when the sheet members 31a are overlapped, the total thickness of the overlapped sheet members 31a may be within the above range. By setting the wall thickness of the tube within the above range, deformation of the object 33 due to external pressure such as the filter 31 can be suppressed.
 物体33は、横断面が中空である中空部材としたが、フィルタ31のろ過率よりも低いろ過率であればこの構成に限られない。物体33は、例えば、紙よりもろ過率が低い酢酸セルロース繊維等の横断面が中実である中実部材により成形されてもよい。
 物体33の中心線方向の端部の形状は、図1に示す例では平面であるが、これに限られず、平面でなくてもよい。
Although the object 33 is a hollow member having a hollow cross section, the configuration is not limited to this as long as the filtration rate is lower than that of the filter 31. The object 33 may be formed of a solid member having a solid cross section, such as cellulose acetate fiber, which has a filtration rate lower than that of paper.
The shape of the end portion of the object 33 in the center line direction is flat in the example shown in FIG. 1, but is not limited to this and does not have to be flat.
 図1に示す第1実施形態に係る香味吸引物品1において、物体33に対応する位置(図5における領域301)でのフィルタ部30の硬さは、Borgwaldt DD60A Densimeter(ボルグワルド社製、以下、「測定装置8」と記載する。)で測定した際に85%以上が好ましく、更には90%以上が好ましい。硬さは理論的に100%以下であり、通常は98%以下が好ましい。フィルタ部30の硬さがこれらの数値を満たすと、フィルタ部30の所望の位置に所望の硬さを付与することが可能となり、香味吸引物品の咥え心地や手ごたえを向上させ、更に香味吸引物品が非燃焼加熱型である場合に吸引装置へ香味吸引物品を差し込み装着する際の作業性を向上させることが可能となる。なお、測定対象となるフィルタ部30とは、物体33等が配置されたフィルタ31とその外周面に巻かれる巻取紙35及びチップペーパー40を合わせた柱状体を指す。巻取紙35を有さない場合は、フィルタ31の外周面をチップペーパー40により巻かれた柱状体を指す。
 硬さについて、図6,図7及び図19を用いて説明する。図6は、第1実施形態に係る硬さの測定装置8の説明図であり、(A)は測定装置8全体の斜視図を示し、(B)は測定装置8の使用例を示す図である。図7は、第1実施形態に係る硬さの測定装置8の他の使用例を示す図である。図19は、第1実施形態における硬さの定義を示す説明図である。
 本実施形態において、「硬さ」は、測定対象物を変形するための抵抗を意味する。
 物体33に対応する位置(図5における領域301)のフィルタ部30に対して負荷Fをかけた際に、フィルタ部は直径方向(高さ方向)に歪みを生じる。測定装置8においては、台座88にフィルタ部30を10本または20本並べて、接触子86で所定重量所定時間荷重をかけた時のフィルタ部30の直径変化(歪み)が測定される。荷重をかける前のフィルタ部(図19における311)の直径Ds(歪み前直径)と、荷重をかけた方のフィルタ部(図19における312)の高さDdとを用いて、硬さは次式で表わす。
   硬さ(%)=(Dd(歪み後高さ))÷(Ds(歪み前直径))×100
 なお、測定は、2kgの荷重を20秒間かけた後に、当該荷重をかけた状態で実施する。
In the flavor suction article 1 according to the first embodiment shown in FIG. 1, the hardness of the filter part 30 at the position corresponding to the object 33 (region 301 in FIG. 5) is preferably 85% or more, more preferably 90% or more, when measured with a Borgwaldt DD60A Densimeter (manufactured by Borgwald, hereinafter referred to as "measuring device 8"). Theoretically, the hardness is 100% or less, and usually 98% or less is preferable. When the hardness of the filter part 30 satisfies these numerical values, it is possible to impart a desired hardness to a desired position of the filter part 30, improving the bite comfort and response of the flavor suction article, and further improving the workability when inserting and attaching the flavor suction article to an inhalation device when the flavor suction article is a non-combustion heating type. The filter part 30 to be measured refers to a columnar body made up of the filter 31 on which the object 33 or the like is arranged, and the wrapping paper 35 and tip paper 40 wound around the outer circumferential surface of the filter 31. When the filter does not have wrapping paper 35, it refers to a columnar body in which the outer peripheral surface of the filter 31 is wrapped with tipping paper 40.
Hardness will be described with reference to Fig. 6, Fig. 7 and Fig. 19. Fig. 6 is an explanatory diagram of the hardness measuring device 8 according to the first embodiment, (A) showing a perspective view of the whole measuring device 8, and (B) showing an example of use of the measuring device 8. Fig. 7 is a diagram showing another example of use of the hardness measuring device 8 according to the first embodiment. Fig. 19 is an explanatory diagram showing the definition of hardness in the first embodiment.
In this embodiment, "hardness" refers to the resistance to deformation of the object to be measured.
When a load F is applied to the filter portion 30 at a position corresponding to the object 33 (region 301 in FIG. 5), the filter portion is distorted in the diameter direction (height direction). In the measuring device 8, 10 or 20 filter portions 30 are arranged on a base 88, and a predetermined weight and time are applied by the contacts 86 to measure the change in diameter (distortion) of the filter portion 30. The hardness is expressed by the following equation using the diameter Ds (diameter before distortion) of the filter portion before the load is applied (311 in FIG. 19) and the height Dd of the filter portion to which the load is applied (312 in FIG. 19).
Hardness (%) = (Dd (height after distortion)) ÷ (Ds (diameter before distortion)) × 100
The measurement is carried out after a load of 2 kg is applied for 20 seconds and then in a state in which the load is still applied.
 測定装置8においては、接触子86と測定対象のフィルタ部30との接点は20点ある。測定対象のフィルタ部30の長さが長い場合(2つの壁82の距離以上の長さがある場合)は、図6(B)に示すように、フィルタ部10本を台座88にセットして測定を行う。測定対象のフィルタ部30が短い場合、もしくは、測定対象のフィルタ部の局所的な箇所の測定を行ないたいときは、図7に示すようにフィルタ部10本を2セット(合計20本)準備し、相向かいに台座にセットして測定を行う。なお、いずれの場合も、測定したい局所的な箇所が接触子24と係合するようにフィルタ部30はセットされる。 
以上は測定装置8を用いた測定について説明を行ったが、20の接触点を有していて、同一荷重2kg、同一時間20秒であれば、他の測定装置8を用いなくても同じ硬さの評価は実施可能である。
In the measuring device 8, there are 20 points of contact between the contacts 86 and the filter part 30 to be measured. When the filter part 30 to be measured is long (longer than the distance between the two walls 82), measurement is performed with 10 filter parts set on a pedestal 88 as shown in Fig. 6(B). When the filter part 30 to be measured is short, or when it is desired to measure a localized portion of the filter part to be measured, two sets of 10 filter parts (20 in total) are prepared as shown in Fig. 7 and set opposite each other on the pedestal for measurement. In either case, the filter part 30 is set so that the localized portion to be measured engages with the contacts 24.
The above describes measurements using the measuring device 8, but if there are 20 contact points, the same load of 2 kg, and the same time of 20 seconds, the same hardness evaluation can be performed without using another measuring device 8.
 また、図1に示す第1実施形態に係る香味吸引物品1において、物体33に対応する位置(図5における領域301)でのフィルタ部30の所定歪み時の応力は所定範囲であることが好ましく、具体的には歪率10%の時に1.0N以上10N以下が好ましく、更には1.5N以上9N以下が更に好ましい。これらの範囲内にあることで、フィルタ部30の所望の位置に所望の硬さを付与することが可能となり、香味吸引物品の咥え心地や手ごたえを向上させ、更に香味吸引物品が非燃焼加熱型である場合に吸引装置へ香味吸引物品を差し込み装着する際の作業性を向上させることが可能となる。加えて、物体33に対応しない位置(図5における領域302)でのフィルタ部30の所定歪み時の応力も所定範囲であることが好ましく、具体的には歪率10%の時に0.2N以上1.5N以下が好ましく、更には0.4N以上1.4N以下が更に好ましい。物体33に対応する位置の所定歪み時の応力と合わせて、それぞれ好ましい範囲に応力が含まれることにより、香味吸引物品の咥え心地や作業性等が向上することができる。これらの応力を、本実施形態では、「所定歪み時の応力」と記す。 In addition, in the flavor suction article 1 according to the first embodiment shown in FIG. 1, the stress of the filter part 30 at a predetermined strain at a position corresponding to the object 33 (region 301 in FIG. 5) is preferably within a predetermined range, specifically, 1.0 N or more and 10 N or less at a strain rate of 10%, and even more preferably 1.5 N or more and 9 N or less. By being within these ranges, it is possible to impart a desired hardness to a desired position of the filter part 30, improving the bite comfort and feel of the flavor suction article, and further improving the workability when inserting and attaching the flavor suction article to the suction device when the flavor suction article is of a non-combustion heating type. In addition, the stress of the filter part 30 at a predetermined strain at a position not corresponding to the object 33 (region 302 in FIG. 5) is also preferably within a predetermined range, specifically, 0.2 N or more and 1.5 N or less at a strain rate of 10%, and even more preferably 0.4 N or more and 1.4 N or less. By including the stress at the position corresponding to the object 33 at the time of the specified strain within each preferred range, the comfort of holding the flavor inhalation article in the mouth and ease of use can be improved. In this embodiment, these stresses are referred to as "stresses at the time of the specified strain."
 フィルタ部30の所定歪み時の応力の測定方法を、図20及び図21を用いて説明する。図20は、第1実施形態における所定歪み時の応力を模式的に示す説明図である。図21は、歪率と応力の関係を模式的に示す図である。「所定歪み時の応力」が変形するための抵抗であることは、 前述した測定装置8で測定した「硬さ」と同じ原理である。 
「所定歪み時の応力」では、図20に示すように、フィルタ部30の直径Dの10%相当の長さ、すなわちD/10をフィルタ部30の直径方向に押し込んだ時(図20の311から312へ変形させた時)に、レオメータ47の押し棒47Aに作用する反発力をフィルタ部30の「所定歪み時の応力」とする。図21の曲線Bに示すように、物体に対応しない位置のフィルタ部30の応力は小さい数値で、歪率にほぼ比例する関係にあるのに対して、曲線Aに示されるように、物体に対応する位置のフィルタ部30の応力は、物体の対応しない位置のフィルタ部30より応力は大きく、曲線Bは歪率が大きくなるに従って増加率が小さくなる。本実施形態では、歪率10%における、応力の数値を「所定歪み時の応力」とする。
 フィルタ部30の軸方向の長さが短い場合や、円周が小さい場合には、前述した測定装置8による測定は困難な場合があるが、「所定歪み時の応力」は容易に測定することができる。
 本実施形態における「所定歪み時の応力」の測定は、株式会社サン科学製のレオメータ、型式番号CR-3000EX-Lを用いた。押し棒47Aには、ステンレス製冶具で構成され、その先端に直径15mmの円盤状の当接部を有するものを用いた。レオメータ47の押し棒47Aの移動速度は、10mm/minとした。フィルタ部30の「所定歪み時の応力」を測定する場合に、フィルタ部30の軸方向の長さを10mmとした。測定対象のフィルタ部30の長さが10mmに満たない場合は複数本のロッドを縦方向に並べて合計長さが10mmとなるように調整して測定を行った。
A method for measuring the stress at a predetermined strain of the filter section 30 will be described with reference to Figs. 20 and 21. Fig. 20 is an explanatory diagram showing a model of the stress at a predetermined strain in the first embodiment. Fig. 21 is a diagram showing a model of the relationship between the strain rate and the stress. The fact that the "stress at a predetermined strain" is the resistance to deformation is based on the same principle as the "hardness" measured by the measuring device 8 described above.
With regard to "stress at a predetermined strain", the repulsive force acting on the push rod 47A of the rheometer 47 when the filter portion 30 is pressed in the diametric direction by a length equivalent to 10% of the diameter D of the filter portion 30, i.e., D/10 (when the filter portion 30 is deformed from 311 to 312 in FIG. 20) is taken as the "stress at a predetermined strain" of the filter portion 30. As shown by curve B in FIG. 21, the stress of the filter portion 30 at a position not corresponding to an object is a small numerical value and is approximately proportional to the strain rate, whereas as shown by curve A, the stress of the filter portion 30 at a position corresponding to an object is greater than that of the filter portion 30 at a position not corresponding to an object, and the rate of increase of curve B decreases as the strain rate increases. In this embodiment, the numerical value of the stress at a strain rate of 10% is taken as the "stress at a predetermined strain".
When the axial length of the filter portion 30 is short or the circumference is small, it may be difficult to perform measurement using the measuring device 8 described above, but the "stress at a specified strain" can be easily measured.
In this embodiment, the "stress at a specified strain" was measured using a rheometer manufactured by Sun Scientific Co., Ltd., model number CR-3000EX-L. The push rod 47A was made of a stainless steel jig, and had a disk-shaped abutment part with a diameter of 15 mm at its tip. The moving speed of the push rod 47A of the rheometer 47 was 10 mm/min. When measuring the "stress at a specified strain" of the filter part 30, the axial length of the filter part 30 was set to 10 mm. When the length of the filter part 30 to be measured was less than 10 mm, multiple rods were arranged vertically and adjusted so that the total length was 10 mm, and the measurement was performed.
 図8は、第1実施形態に係る香味吸引物品1の縦断面の他の例を示す図であり、物体33は中実部材であり、(A)は第2側が先鋭である物体33、(B)は第1側から第2側に向かって幅が小さくなっている物体33が配置された香味吸引物品1の縦断面を示す図である。
 例えば、物体33の中心線方向の端部の形状は、図8(A)に示すように、物体33の第1側の端面が平面であり、物体33の第2側の端面が先鋭であってもよい。また、例えば、図8(B)に示すように、第2側領域の方が、第1側領域に比べて物体33の幅が相対的に小さくなってもよい。
Figure 8 shows another example of a longitudinal section of the flavor inhalation article 1 according to the first embodiment, in which the object 33 is a solid member, and (A) shows a longitudinal section of the flavor inhalation article 1 in which the object 33 has a sharp point on the second side, and (B) shows a longitudinal section of the flavor inhalation article 1 in which the object 33 has a width that decreases from the first side to the second side.
For example, the shape of the end of the object 33 in the center line direction may be such that the end face on the first side of the object 33 is flat and the end face on the second side of the object 33 is sharp, as shown in Fig. 8(A). Also, for example, the width of the object 33 may be relatively smaller in the second side region than in the first side region, as shown in Fig. 8(B).
 ここで、図1,図9,図10を用いて、物体33の配置の具体例を説明する。
 図9は、第1実施形態に係る香味吸引物品1の縦断面の他の例を示す図であり、(A)は物体33がフィルタ31内の第2側に位置する状態、(B)は物体33がフィルタ31内の中央寄りに位置する状態を示す図である。
 図10は、第1実施形態に係る香味吸引物品1の縦断面の他の例を示す図であり、(A)は中心線方向の大きさがフィルタ31と同一の物体33がフィルタ31内に位置する状態、(B)は複数の物体33がフィルタ31内に位置する状態を示す図である。
 物体33は、物体33がフィルタ31の第2側の端面から突出しないように配置されていることが好ましい。
Here, a specific example of the arrangement of the object 33 will be described with reference to FIGS.
Figure 9 is a diagram showing another example of a longitudinal section of the flavor inhalation article 1 according to the first embodiment, in which (A) shows a state in which the object 33 is located on the second side within the filter 31, and (B) shows a state in which the object 33 is located toward the center within the filter 31.
Figure 10 is a diagram showing another example of a longitudinal section of the flavor inhalation article 1 according to the first embodiment, in which (A) shows a state in which an object 33 having a size in the center line direction equal to that of the filter 31 is positioned within the filter 31, and (B) shows a state in which a plurality of objects 33 are positioned within the filter 31.
The object 33 is preferably arranged so that the object 33 does not protrude from the end face on the second side of the filter 31 .
 図1に示す例では、フィルタ31の中心線方向の大きさよりも小さい中空の物体33が、フィルタ31内の第1側(基材部10側)に位置する。具体的には、物体33が、フィルタ31内の上流側の領域に配置されている。フィルタ31内の第1側(基材部10側)に物体33が配置されていることで、好適なエアロゾルのろ過を実現させつつ、フィルタ31の第2側の端面から物体33が見えないようにすることができる。また、フィルタ31内の第1側(基材部10側)に物体33が配置されていると、フィルタ31の第1側の強度を高めて、図2に示すように吸引装置100への香味吸引物品1を装着する作業を実施し易くなる。 1, a hollow object 33 smaller than the size of the filter 31 in the center line direction is located on the first side (substrate 10 side) of the filter 31. Specifically, the object 33 is disposed in the upstream region of the filter 31. By disposing the object 33 on the first side (substrate 10 side) of the filter 31, it is possible to realize suitable filtration of the aerosol while preventing the object 33 from being seen from the end face of the second side of the filter 31. Furthermore, when the object 33 is disposed on the first side (substrate 10 side) of the filter 31, the strength of the first side of the filter 31 is increased, making it easier to attach the flavor inhalation article 1 to the inhalation device 100 as shown in FIG. 2.
 図9(A)に示す例では、フィルタ31の中心線方向の大きさよりも小さく中実の物体33が、フィルタ31内の第2側(下流側)に位置する。具体的には、物体33が、フィルタ31内の第2側の領域に配置されている。フィルタ31内の第2側(吸口端)の領域に物体33が配置されていることで、マウスピースセグメント50のうちのユーザが咥える領域の強度を高めて咥え心地を良くすることができる。物体33が中空であっても第2側の領域の強度を高めることができれば、同様に咥え心地を良くすることができる。
 物体33の第2側の端面が、図9(A)に示す例ではフィルタ31の第2側の端面に位置するが、これに限られず、両者の端面の位置が一致しなくてもよい。例えば、物体33がフィルタ31内の第2側に位置する場合、物体33の第2側の端面がフィルタ31の第2側の端面から2mm以上離れていてもよい。物体33の第2側の端面がフィルタ31の第2側の端面から2mm以上離れていることで、フィルタ部30の中心線方向において、フィルタ31の第2側の端面から物体33が見えないようにすることができる。
In the example shown in Fig. 9 (A), a solid object 33 smaller than the size of the filter 31 in the center line direction is located on the second side (downstream side) within the filter 31. Specifically, the object 33 is disposed in the second side region within the filter 31. By disposing the object 33 in the second side (suction end) region within the filter 31, the strength of the region of the mouthpiece segment 50 that is held in the user's mouth can be increased, improving the comfort of holding it in the mouth. Even if the object 33 is hollow, if the strength of the second side region can be increased, the comfort of holding it in the mouth can be similarly improved.
9A, the end face on the second side of the object 33 is located at the end face on the second side of the filter 31, but the present invention is not limited to this, and the positions of the two end faces do not have to coincide. For example, when the object 33 is located on the second side within the filter 31, the end face on the second side of the object 33 may be 2 mm or more away from the end face on the second side of the filter 31. By having the end face on the second side of the object 33 be 2 mm or more away from the end face on the second side of the filter 31, it is possible to make the object 33 invisible from the end face on the second side of the filter 31 in the center line direction of the filter section 30.
 フィルタ31の中心線方向の大きさよりも小さい物体33の配置は、フィルタ31内の第1側の領域又は第2側の領域に限られない。
 図9(B)に示す例では、フィルタ31の中心線方向の大きさよりも小さい物体33が、中心線方向においてフィルタ31内の中央寄りに位置する。具体的には、物体33が、中心線方向においてフィルタ31内の中央寄りの領域に配置されている。フィルタ31内の中央寄りの領域に物体33が配置されていることで、マウスピースセグメント50が噛まれた際のユーザの歯に対応する領域の強度を高めることができる。
The arrangement of the object 33 that is smaller than the size of the filter 31 in the center line direction is not limited to the first side region or the second side region within the filter 31 .
9(B), an object 33 smaller than the size of the filter 31 in the center line direction is located toward the center of the filter 31 in the center line direction. Specifically, the object 33 is disposed in a region toward the center of the filter 31 in the center line direction. By disposing the object 33 in a region toward the center of the filter 31, it is possible to increase the strength of the region that corresponds to the user's teeth when the mouthpiece segment 50 is bitten.
 物体33は、物体33がフィルタ31の第2側の端面から突出しないように配置されていればよく、上述の構成に限られない。
 図10(A)に示すように、中心線方向の大きさがフィルタ31と同一の物体33がフィルタ31内に配置されてもよい。
 また、複数の物体33を配置する場合、物体33の配置は、図4(B)に示すような中心線方向における同一の領域に限られない。図10(B)に示すように、フィルタ31内の複数の領域に物体33が配置されてもよい。
 フィルタ31に対する物体33の割合を高めることで、マウスピースセグメント50の強度を高めつつ、フィルタ部30によるエアロゾルのろ過率を低減させることができる。
The object 33 is not limited to the above-mentioned configuration as long as the object 33 is arranged so as not to protrude from the end face on the second side of the filter 31 .
As shown in FIG. 10A, an object 33 having a size in the center line direction equal to that of the filter 31 may be placed inside the filter 31.
In addition, when multiple objects 33 are arranged, the arrangement of the objects 33 is not limited to the same region in the center line direction as shown in Fig. 4B. As shown in Fig. 10B, the objects 33 may be arranged in multiple regions in the filter 31.
By increasing the ratio of the object 33 to the filter 31, the strength of the mouthpiece segment 50 can be increased while the filtration rate of the aerosol by the filter portion 30 can be reduced.
[基材部10]
 基材部10は、加熱されることでエアロゾルが生成される蒸気を生じるエアロゾル源11と、エアロゾル源11の外周を覆う巻紙12とを有している。また、基材部10は、基材部10の第1側の端面からのエアロゾル源11の脱落を防ぐ先端部材13を有してもよい。基材部10は、エアロゾル源11と先端部材13とが巻紙12に巻かれることで円柱状に形成されている。エアロゾル源11は、例えば、たばこ刻み又はたばこ原料を、粒状、シート状、又は粉末状に成形した加工物等の、たばこ由来のものであってもよい。また、エアロゾル源11は、たばこ以外の植物(例えばミント及びハーブ等)から作られた、非たばこ由来のものを含んでいてもよい。一例として、エアロゾル源11は、香料を含んでいてもよい。香料の種類は、特に限定されず、良好な香味の付与の観点から、特に好ましくはメンソールである。また、これらの香料は1種を単独で用いても、又は2種以上を併用してもよい。吸引装置100が医療用吸入器である場合、エアロゾル源11は、患者が吸入するための薬剤を含んでもよい。なお、エアロゾル源11は固体に限られるものではなく、例えば、グリセリン及びプロピレングリコール等の多価アルコール、並びに水等の液体であってもよい。基材部10の少なくとも一部は、香味吸引物品1が保持部140に保持された状態において、保持部140の内部空間141に収容される。
[Substrate part 10]
The substrate 10 has an aerosol source 11 that generates steam that generates an aerosol when heated, and a cigarette paper 12 that covers the outer circumference of the aerosol source 11. The substrate 10 may also have a tip member 13 that prevents the aerosol source 11 from falling off from the end face on the first side of the substrate 10. The substrate 10 is formed into a cylindrical shape by wrapping the aerosol source 11 and the tip member 13 around the cigarette paper 12. The aerosol source 11 may be tobacco-derived, such as a processed product in which tobacco shreds or tobacco raw material is molded into a granular, sheet, or powder form.

Here, the aerosol source 11 including tobacco shreds will be described. The material of the tobacco shreds contained in the aerosol source 11 is not particularly limited, and known materials such as lamina and ribs can be used. Alternatively, the tobacco shreds may be made by crushing dried tobacco leaves to an average particle size of 20 μm to 200 μm to obtain tobacco shreds, homogenizing the shredded tobacco, and processing the shredded tobacco into a sheet (hereinafter, simply referred to as a homogenized sheet). Furthermore, the aerosol source 11 may be filled with a homogenized sheet having a size approximately equal to the size of the center line direction of the substrate 10, which is shredded approximately horizontally to the center line direction of the substrate 10, to form a so-called strand type.
In addition, the width of the tobacco shreds is preferably 0.5 mm or more and 2.0 mm or less when filling the aerosol source 11 .

Examples include flue-cured tobacco, burley, orient, native tobacco, other Nicotiana tabacum varieties, Nicotiana rustica varieties, and mixtures of these. Mixtures can be used by blending varieties appropriately to achieve the desired flavor. Details of tobacco varieties are disclosed in "Encyclopedia of Tobacco, Tobacco Research Center, March 31, 2009." There are several conventional methods for manufacturing homogenized sheets, that is, methods for grinding tobacco leaves and processing them into homogenized sheets. The first method is to produce a paper-making sheet using a papermaking process. The second method is to mix a suitable solvent such as water with ground tobacco leaves to homogenize them, and then cast the homogenized mixture thinly on a metal plate or metal plate belt and dry it to produce a cast sheet. The third method is to mix a suitable solvent such as water with ground tobacco leaves to homogenize them, and extrude the mixture into a sheet to produce a rolled sheet. Details of the types of homogenizing sheets are disclosed in the "Encyclopedia of Tobacco, Tobacco Research Center, March 31, 2009."
 エアロゾル源11の水分含有量は、エアロゾル源11の全量に対して10質量%以上15質量%以下を挙げることができ、11質量%以上13質量%以下であることが好ましい。このような水分含有量であると、巻染みの発生を抑制し、基材部10の製造時の巻上適性を良好にする。 The moisture content of the aerosol source 11 can be 10% by mass or more and 15% by mass or less, and is preferably 11% by mass or more and 13% by mass or less, based on the total amount of the aerosol source 11. Such a moisture content suppresses the occurrence of stains on the roll and improves the suitability of the base material 10 for rolling during its manufacture.
 エアロゾル源11は、特に限定されず、用途に応じて種々の天然物からの抽出物質及び/又はそれらの構成成分を含んでいてもよい。抽出物質及び/又はそれらの構成成分として、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を挙げることができる。
 エアロゾル源11中の抽出物質及び/又はそれらの構成成分の含有量は、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、良好な香味を付与する観点から、エアロゾル源11の全量に対して通常5質量%以上であり、好ましくは10質量%以上である。また、エアロゾル源11中の抽出物質及び/又はそれらの構成成分の含有量は、通常50質量%以下であり、好ましくは15質量%以上、25質量%以下である。

 また、エアロゾル源11は、たばこシートから構成されてもよい。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。 The aerosol source 11 may also be composed of a tobacco sheet. The number of tobacco sheets may be one, or two or more.
 エアロゾル源11が、1枚のたばこシートから構成される場合の態様としては、例えば、その一辺が、被充填物の中心線方向の大きさと同程度の大きさを有するたばこシートが、被充填物の中心線方向と水平に複数回折り返された状態で充填される態様(いわゆるギャザーシート)が挙げられる。また、その一辺が、被充填物の中心線方向の大きさと同程度の大きさを有するたばこシートを、被充填物の中心線方向と直交する方向に巻き回された状態で充填される態様も挙げられる。 When the aerosol source 11 is composed of a single tobacco sheet, for example, a tobacco sheet with one side approximately the same size as the centerline of the filling is folded multiple times horizontally to the centerline of the filling (so-called gathered sheet) is included. Another example is a tobacco sheet with one side approximately the same size as the centerline of the filling, rolled up in a direction perpendicular to the centerline of the filling.
 エアロゾル源11が、2枚以上のたばこシートから構成される場合の態様としては、例えば、その1辺が、被充填物の中心線方向の大きさと同程度の大きさを有する複数のたばこシートが、同心状に配置されるように、被充填物の中心線方向と直交する方向に巻き回された状態で充填される態様が挙げられる。「同心状に配置される」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。
 「同心状に配置される」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。
 2枚以上のたばこシートはすべて同じ組成あるいは物性であってもよいし、各たばこシートの中の一部又は全部が異なる組成あるいは物性であってもよい。また、各たばこシートの厚みは、それぞれが同一であってもよく、異なっていてもよい。
 各たばこシートの厚みについては制限されないが、伝熱効率と強度の兼ね合いから、150μm以上1000μm以下が好ましく、200μm以上600μm以下がより好ましい。
In the case where the aerosol source 11 is composed of two or more tobacco sheets, for example, a plurality of tobacco sheets, one side of which has a size approximately equal to the size of the center line direction of the filling, are packed in a state of being wound in a direction perpendicular to the center line direction of the filling so as to be concentrically arranged. "Concentrically arranged" means that the centers of all the tobacco sheets are arranged at approximately the same position.
The term "concentrically arranged" refers to the arrangement in which the centers of all the tobacco sheets are located at approximately the same position. The number of tobacco sheets is not particularly limited, but examples include embodiments in which the number of tobacco sheets is 2, 3, 4, 5, 6, or 7.
The two or more tobacco sheets may all have the same composition or physical properties, or some or all of the tobacco sheets may have different compositions or physical properties. Furthermore, the thicknesses of the tobacco sheets may be the same or different.
There are no limitations on the thickness of each tobacco sheet, but in terms of the balance between heat transfer efficiency and strength, the thickness is preferably 150 μm or more and 1000 μm or less, and more preferably 200 μm or more and 600 μm or less.
 エアロゾル源11は、幅の異なる複数のたばこシートを準備して、第1側から第2側に向かって幅が小さくなるように積層した積層体を調製し、これを巻管に通して巻き上げ成形することで製造できる。
 この製造方法によれば、複数のたばこシートが、中心線方向に延在するとともに、CLを中心として同心状に配置されるようになる。
 この製造方法において、積層体は巻上げ成形後に隣接するたばこシート間に非接触部が形成されるように調製されることが好ましい。複数のたばこシート間に、たばこシートが接触しない非接触部(隙間)が存在すると、香味流路を確保して香味成分のデリバリー効率を高めることができる。他方で、複数のたばこシートの接触部分を介して加熱部121からの熱を外側のたばこシートに伝達できるので高い伝熱効率を確保することができる。
 複数のたばこシート間に、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。
 巻紙12を含めた基材部10を調製する場合には、積層体の第1側の端面に巻紙12を配置してもよい。
The aerosol source 11 can be manufactured by preparing a plurality of tobacco sheets of different widths, stacking them so that the width decreases from the first side to the second side to prepare a laminate, and passing the laminate through a winding tube to roll and mold it.
According to this manufacturing method, a plurality of tobacco sheets extend in the center line direction and are arranged concentrically around the CL.
In this manufacturing method, the laminate is preferably prepared so that a non-contact portion is formed between adjacent tobacco sheets after rolling. If there is a non-contact portion (gap) between multiple tobacco sheets where the tobacco sheets are not in contact, a flavor flow path can be secured and the delivery efficiency of the flavor components can be improved. On the other hand, heat from the heating unit 121 can be transferred to the outer tobacco sheet via the contact portion of the multiple tobacco sheets, so high heat transfer efficiency can be secured.
In order to provide non-contact portions between multiple tobacco sheets, methods that can be used to prepare a laminate include, for example, using an embossed tobacco sheet, laminating adjacent tobacco sheets without bonding their entire surfaces together, laminating adjacent tobacco sheets by bonding only a portion of the sheets together, or laminating adjacent tobacco sheets by lightly bonding their entire surfaces or a portion of the sheets together so that they can be peeled off after rolling and molding.
When preparing the base material 10 including the wrapping paper 12, the wrapping paper 12 may be disposed on the end face of the first side of the laminate.
 たばこシートには、グリセリン、プロピレングリコール、1,3-ブタンジオール等のポリオール等を添加してもよい。たばこシートへの添加量は、たばこシートの乾燥質量に対して5質量%以上50質量%以下が好ましく、15質量%以上25質量%以下がより好ましい。

The tobacco sheet can be appropriately produced by a known method such as papermaking, slurry, rolling, etc. The above-mentioned homogenized sheet can also be used.
In the case of papermaking, tobacco can be produced by a method including the following steps: 1) Dried tobacco leaves are roughly crushed and extracted with water to separate the water extract and residue. 2) The water extract is dried under reduced pressure and concentrated. 3) Pulp is added to the residue, which is then fiberized in a refiner and made into paper. 4) A concentrated liquid of the water extract is added to the paper-made sheet and dried to produce a tobacco sheet. In this case, a step of removing some components such as nitrosamines may be added (see JP-T 2004-510422).
In the case of the slurry method, the tobacco leaf can be produced by a method including the following steps: 1) Mixing water, pulp, and a binder with crushed tobacco leaves. 2) Spreading (casting) the mixture thinly and drying it. In this case, a step of irradiating the slurry of water, pulp, and a binder with crushed tobacco leaves with ultraviolet light or X-rays to remove some of the components such as nitrosamines may be added.
 この他、国際公開第2014/104078号に記載されているように、以下の工程を含む方法によって製造された不織布状のたばこシートを用いることもできる。1)粉粒状のたばこ葉と結合剤を混合する。2)混合物を不織布によって挟む。3)積層物を熱溶着によって一定形状に成形し、不織布状のたばこシートを得る。

Furthermore, when the basis weight is 25 gsm or more and 35 gsm or less, the filler content is preferably 15% by mass or more and 45% by mass or less, and when the basis weight is 35 gsm or more and 45 gsm or less, the filler content is preferably 25% by mass or more and 45% by mass or less.
As the filler, calcium carbonate, titanium dioxide, kaolin, etc. can be used, but it is preferable to use calcium carbonate from the viewpoint of enhancing flavor and whiteness.
 巻紙12には、原紙や填料以外の種々の助剤を添加してもよく、例えば、耐水性を向上させるために、耐水性向上剤を添加することができる。耐水性向上剤には、湿潤紙力増強剤(WS剤)及びサイズ剤が含まれる。湿潤紙力増強剤の例を挙げると、尿素ホルムアルデヒド樹脂、メラミンホルムアルデヒド樹脂、ポリアミドエピクロルヒドリン(PAE)等である。また、サイズ剤の例を挙げると、ロジン石けん、アルキルケテンダイマー(AKD)、アルケニル無水コハク酸(ASA)、ケン化度が90%以上の高ケン化ポリビニルアルコール等である。
 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)。
Various auxiliaries other than the base paper and fillers may be added to the wrapping paper 12. For example, a water resistance improver may be added to improve water resistance. The water resistance improver includes a wet strength agent (WS agent) and a sizing agent. Examples of the wet strength agent include urea formaldehyde resin, melamine formaldehyde resin, polyamide epichlorohydrin (PAE), etc. Examples of the sizing agent include rosin soap, alkyl ketene dimer (AKD), alkenyl succinic anhydride (ASA), highly saponified polyvinyl alcohol with a saponification degree of 90% or more, etc.
As an auxiliary, a paper strength enhancer may be added, for example, polyacrylamide, cationic starch, oxidized starch, CMC, polyamide epichlorohydrin resin, polyvinyl alcohol, etc. In particular, it is known that the use of a very small amount of oxidized starch improves the air permeability (JP 2017-218699 A).
 巻紙12には、その表面及び裏面の2面のうち、少なくとも1面にコーティング剤が添加されてもよい。コーティング剤としては特に制限はないが、紙の表面に膜を形成し、液体の透過性を減少させることができるコーティング剤が好ましい。例えばアルギン酸及びその塩(例えばナトリウム塩)、ペクチンのような多糖類、エチルセルロース、メチルセルロース、カルボキシメチルセルロース、ニトロセルロースのようなセルロース誘導体、デンプンやその誘導体(例えばカルボキシメチルデンプン、ヒドロキシアルキルデンプン及びカチオンデンプンのようなエーテル誘導体、酢酸デンプン、リン酸デンプン及びオクテニルコハク酸デンプンのようなエステル誘導体)を挙げることができる。 A coating agent may be added to at least one of the two surfaces of the wrapping paper 12, the front and back. There are no particular limitations on the coating agent, but a coating agent that can form a film on the surface of the paper and reduce liquid permeability is preferred. Examples include alginic acid and its salts (e.g., sodium salts), polysaccharides such as pectin, cellulose derivatives such as ethyl cellulose, methyl cellulose, carboxymethyl cellulose, and nitrocellulose, starch and its derivatives (e.g., ether derivatives such as carboxymethyl starch, hydroxyalkyl starch, and cationic starch, and ester derivatives such as starch acetate, starch phosphate, and starch octenyl succinate).
[冷却部20]
 冷却部20は、基材部10とフィルタ部30とに隣接して配置され、シート21が巻かれることで円筒等の横断面が中空(空洞)となるように成形された部位である。冷却部20は、基材部10が加熱されることで生成された蒸気を冷却してエアロゾルを生成する。
 具体的には、冷却部20は、紙からなるシート21が巻かれることで成形された紙管である。冷却部20は、少なくとも紙を含む複数のシート21が互いに貼り合わせられ、かつ、らせん状に巻きつけられて成形された紙管、いわゆるスパイラル紙管である。スパイラル紙管の製法では、横断面が円形の紙管を容易に成形することが可能である。冷却部20にスパイラル紙管を採用することで、冷却部20の面積を抑えつつ、冷却部20の強度を向上させることができる。また、香料成分や、香味成分、たばこ粉砕物等を含むシート部材31aを紙と組合せて貼り合わせることで、エアロゾルに新たな香喫味を付与することができる。
[Cooling section 20]
The cooling unit 20 is disposed adjacent to the base material 10 and the filter unit 30, and is a portion formed so that the cross section of a cylinder or the like is hollow (hollow) by wrapping the sheet 21 around it. The cooling unit 20 cools the steam generated by heating the base material 10 to generate an aerosol.
Specifically, the cooling section 20 is a paper tube formed by winding a sheet 21 made of paper. The cooling section 20 is a so-called spiral paper tube, which is a paper tube formed by bonding a plurality of sheets 21 including at least paper to each other and winding them in a spiral shape. The spiral paper tube manufacturing method makes it possible to easily form a paper tube having a circular cross section. By adopting a spiral paper tube for the cooling section 20, it is possible to improve the strength of the cooling section 20 while suppressing the area of the cooling section 20. In addition, by combining and bonding a sheet member 31a containing a fragrance component, a flavor component, tobacco powder, etc. with paper, it is possible to impart a new flavor and taste to the aerosol.
 その他、冷却部20は、紙が何重にも円筒状に巻かれて成形された紙管、いわゆるストレート紙管であってもよい。ストレート紙管の製法では、スパイラル紙管の製法に比べて、紙の貼り付けに使用される糊の量を少なくすることができる。
 また、冷却部20は、少なくとも紙を含む複数のシート21が積層されて成形された紙管であってもよい。複数のシート21が積層されることで、シート21の各々の坪量が小さい場合にも冷却部20の強度を維持させることができる。
Alternatively, the cooling unit 20 may be a paper tube formed by winding paper multiple times into a cylindrical shape, that is, a so-called straight paper tube. In the manufacturing method of a straight paper tube, the amount of glue used to attach the paper can be reduced compared to the manufacturing method of a spiral paper tube.
The cooling section 20 may be a paper tube formed by stacking a plurality of sheets 21 including at least paper. By stacking a plurality of sheets 21, the strength of the cooling section 20 can be maintained even when the basis weight of each of the sheets 21 is small.
 冷却部20の横断面は実質的に円形であり、その円周は、製品のサイズに合わせて適宜変更し得るが、後述するフィルタ31の円周と略同一であることが好ましい。なお、横断面が円形でない場合、上記の円周は、その断面の面積と同じ面積を有する円で仮定し、その円における円周が適用される。
 冷却部20の中心線方向の大きさは、製品のサイズに合わせて適宜変更し得るが、通常5mm以上であり、10mm以上であることが好ましく、15mm以上であることがより好ましい。また、冷却部20の中心線方向の大きさは、通常35mm以下であり、30mm以下であることが好ましく、25mm以下であることがより好ましい。冷却部20の中心線方向の大きさを上述した下限以上とすることで、十分な冷却効果を確保して良好な香味を得ることができ、上述した上限以下とすることで、生成した蒸気及びエアロゾルがシート21に付着することによるロスを抑制することができる。
The cross section of the cooling section 20 is substantially circular, and the circumference may be appropriately changed according to the size of the product, but is preferably approximately the same as the circumference of the filter 31 described below. If the cross section is not circular, the circumference is assumed to be a circle having the same area as the cross section, and the circumference of that circle is applied.
The size of the cooling section 20 in the center line direction can be changed appropriately according to the size of the product, but is usually 5 mm or more, preferably 10 mm or more, and more preferably 15 mm or more. The size of the cooling section 20 in the center line direction is usually 35 mm or less, preferably 30 mm or less, and more preferably 25 mm or less. By setting the size of the cooling section 20 in the center line direction to the above-mentioned lower limit or more, a sufficient cooling effect can be ensured to obtain a good flavor, and by setting it to the above-mentioned upper limit or less, loss due to adhesion of the generated steam and aerosol to the sheet 21 can be suppressed.
 例えば、冷却部20は、紙からなるシート21が巻かれることで成形された紙管である。
 具体的には、冷却部20は、少なくとも紙を含む複数のシート21が互いに貼り合わせられ、かつ、らせん状に巻きつけられて成形された紙管、いわゆるスパイラル紙管である。スパイラル紙管の製法では、横断面が円形の紙管を容易に成形することが可能である。冷却部20にスパイラル紙管を採用することで、冷却部20の面積を抑えつつ、冷却部20の強度を向上させることができる。また、香料成分や、香味成分、たばこ粉砕物等を含むシート部材を紙と組み合わせて貼り合わせることで、エアロゾルに新たな香喫味を付与することができる。

 また、冷却部20は、少なくとも紙を含む複数のシート21が積層されて成形された紙管であってもよい。複数のシート21が積層されることで、シート21の各々の坪量が小さい場合にも冷却部20の強度を維持させることができる。
For example, the cooling section 20 is a paper tube formed by winding a sheet 21 made of paper.
Specifically, the cooling section 20 is a paper tube formed by bonding a plurality of sheets 21 including at least paper together and winding them in a spiral shape, that is, a so-called spiral paper tube. The manufacturing method of the spiral paper tube makes it possible to easily form a paper tube having a circular cross section. By adopting a spiral paper tube for the cooling section 20, it is possible to improve the strength of the cooling section 20 while suppressing the area of the cooling section 20. In addition, by combining and bonding a sheet member containing a fragrance component, a flavor component, tobacco powder, etc. with paper, it is possible to impart a new flavor and taste to the aerosol.
Alternatively, the cooling unit 20 may be a paper tube formed by winding paper multiple times into a cylindrical shape, that is, a so-called straight paper tube. In the manufacturing method of a straight paper tube, the amount of glue used to attach the paper can be reduced compared to the manufacturing method of a spiral paper tube.
The cooling section 20 may be a paper tube formed by stacking a plurality of sheets 21 including at least paper. By stacking a plurality of sheets 21, the strength of the cooling section 20 can be maintained even when the basis weight of each of the sheets 21 is small.
 シート21の厚みは、特段制限されず、例えば、50μm以上500μm以下であってよく、また、100μm以上250μm以下であってもよい。なお、シート21の材質は、特段制限されず、例えば、パルプが主成分のものであってよく、また、ポリエチレン、ポリプロピレン、ポリ塩化ビニル、ポリエチレンテレフタラート、ポリ乳酸、酢酸セルロース、及びアルミ箔のいずれかが主成分のもの、又はこれらの任意の組み合わせであってもよい。
 冷却部20は、シート21を巻くことにより成形される部位としたが、筒状に成形された筒状部材の一例であり、横断面が中空であればこの構成に限られない。冷却部20は、例えば、既に横断面が中空である合成樹脂等の管により成形されてもよい。
The thickness of the sheet 21 is not particularly limited and may be, for example, 50 μm to 500 μm, or 100 μm to 250 μm. The material of the sheet 21 is not particularly limited and may be, for example, a material mainly composed of pulp, or a material mainly composed of any of polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate, polylactic acid, cellulose acetate, and aluminum foil, or any combination of these.
The cooling section 20 is a portion formed by rolling the sheet 21, but this is an example of a cylindrical member formed into a cylindrical shape, and is not limited to this configuration as long as the cross section is hollow. The cooling section 20 may be formed, for example, from a tube of synthetic resin or the like that already has a hollow cross section.
 冷却部20には、その周方向に、かつ、同心状に複数の貫通孔60(本技術分野では「ベンチレーションフィルター(Vf)」とも称する。)が設けられている。貫通孔60は、シート21を貫通する孔である。孔の形状は、多角、角丸多角、円、楕円等であることを例示することができる。貫通孔60は、香味吸引物品1の外部から空気を流入できる領域、言い換えると、吸引装置100の保持部140に香味吸引物品1が保持された状態で開口142から突出する領域に存在する。 The cooling section 20 is provided with a plurality of through holes 60 (also referred to as "ventilation filters (Vf)" in this technical field) arranged circumferentially and concentrically. The through holes 60 are holes that penetrate the sheet 21. Examples of the hole shapes include polygonal, rounded polygonal, circular, and elliptical. The through holes 60 are present in an area through which air can flow in from outside the flavor inhalation article 1, in other words, in an area that protrudes from the opening 142 when the flavor inhalation article 1 is held in the holding section 140 of the inhalation device 100.
 貫通孔60が存在することで、吸引される香味成分及びエアロゾルの濃度を調整することができる。また、複数の貫通孔60が存在することで、吸引時に外部から冷却部20の内部に空気が流入し、基材部10から流入する蒸気や空気の温度を下げることができる。さらに、冷却部20に貫通孔60を設ける位置を冷却部20とフィルタ部30との境界から、冷却部20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物(生成物)の冷却部20内での滞留を抑制し、生成物のデリバリー量を向上させることができる。
 なお、基材部10が加熱されることでエアロゾルを凝縮核として生じる蒸気が、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。
The presence of the through-holes 60 allows the concentration of the inhaled flavor components and aerosol to be adjusted. In addition, the presence of a plurality of through-holes 60 allows air to flow from the outside into the cooling section 20 during inhalation, and the temperature of the steam and air flowing in from the substrate section 10 can be lowered. Furthermore, by providing the through-holes 60 in the cooling section 20 within a region of 4 mm or more in the direction toward the cooling section 20 from the boundary between the cooling section 20 and the filter section 30, not only can the cooling capacity be improved, but also the retention of the product (product) generated by heating in the cooling section 20 can be suppressed, and the delivery amount of the product can be improved.
In addition, when the base material 10 is heated, the vapor generated using the aerosol as a condensation nucleus is liquefied by contacting air from the outside and decreasing in temperature, thereby promoting the generation of the aerosol.
 冷却部20にて、同心円上に存在する複数の貫通孔60を1つの貫通孔群として扱った場合、貫通孔群は1つであってもよく、また、2つ以上であってもよい。貫通孔群が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、冷却部20とフィルタ部30との境界から、冷却部20側の方向の4mm未満の領域には貫通孔群を設けないことが好ましい。
 また、香味吸引物品1が、基材部10、冷却部20及びフィルタ部30がチップペーパー40で巻装されてなる態様である場合、チップペーパー40には、冷却部20に設けられた貫通孔60の直上の位置に通気孔が設けられていることが好ましい。このような香味吸引物品1を作製する場合、貫通孔60と重なるような通気孔を設けたチップペーパー40を準備して巻装してもよいが、製造容易性の観点から、貫通孔60を有さない香味吸引物品1を作製した後、冷却部20及びチップペーパー40を同時に貫通する孔を開けることが好ましい。
When a plurality of through holes 60 existing on concentric circles in the cooling section 20 are treated as one through hole group, the number of through hole groups may be one or may be two or more. When two or more through hole groups are present, from the viewpoint of improving the delivery amount of the component generated by heating, it is preferable that no through hole group is provided in a region less than 4 mm in the direction of the cooling section 20 from the boundary between the cooling section 20 and the filter section 30.
Furthermore, when the flavor inhalation article 1 is configured such that the substrate part 10, the cooling part 20, and the filter part 30 are wound with the tipping paper 40, the tipping paper 40 is preferably provided with an air hole at a position directly above the through hole 60 provided in the cooling part 20. When producing such a flavor inhalation article 1, the tipping paper 40 may be prepared and wound with an air hole that overlaps with the through hole 60, but from the viewpoint of ease of production, it is preferable to produce the flavor inhalation article 1 without the through hole 60 and then open a hole penetrating the cooling part 20 and the tipping paper 40 at the same time.
 貫通孔60が存在する領域は、加熱による生成物のデリバリー効率を向上させる観点から、冷却部20とフィルタ部30との境界から、冷却部20側の方向に4mm以上の領域であれば特段制限されないが、さらに生成物のデリバリー効率を向上させる観点から、4.5mm以上の領域であることが好ましく、5mm以上の領域であることがより好ましく、5.5mm以上の領域であることがさらに好ましい。また、貫通孔60が存在する領域は、冷却機能を確保する観点から、冷却部20とフィルタ部30との境界から、15mm以下の領域であることが好ましく、10mm以下の領域であることがより好ましく、7mm以下の領域であることがさらに好ましい。 From the viewpoint of improving the delivery efficiency of the product by heating, the region where the through holes 60 exist is not particularly limited as long as it is a region of 4 mm or more from the boundary between the cooling section 20 and the filter section 30 toward the cooling section 20, but from the viewpoint of further improving the delivery efficiency of the product, it is preferable that it is a region of 4.5 mm or more, more preferably a region of 5 mm or more, and even more preferably a region of 5.5 mm or more. Also, from the viewpoint of ensuring the cooling function, the region where the through holes 60 exist is preferably a region of 15 mm or less from the boundary between the cooling section 20 and the filter section 30, more preferably a region of 10 mm or less, and even more preferably a region of 7 mm or less.
 また、冷却部20と基材部10との境界を基準に考えると、冷却部20の中心線方向の大きさが20mm以上である場合、貫通孔60が存在する領域は、冷却機能を確保する観点から、冷却部20と基材部10との境界から、冷却部20側の方向に5mm以上の領域であることが好ましく、10mm以上の領域であることがより好ましく、13mm以上の領域であることがさらに好ましい。また、貫通孔60が存在する領域は、加熱による生成物のデリバリー効率を向上させる観点から、冷却部20と基材部10との境界から、16mm以下の領域であることが好ましく、15.5mm以下の領域であることがより好ましく、15mm以下の領域であることがさらに好ましく、14.5mm以下の領域であることが特に好ましい。 Furthermore, when the boundary between the cooling section 20 and the substrate 10 is considered as a reference, if the size of the cooling section 20 in the center line direction is 20 mm or more, the region in which the through holes 60 exist is preferably a region of 5 mm or more from the boundary between the cooling section 20 and the substrate 10 toward the cooling section 20 in terms of ensuring the cooling function, more preferably a region of 10 mm or more, and even more preferably a region of 13 mm or more. Furthermore, from the perspective of improving the delivery efficiency of the product by heating, the region in which the through holes 60 exist is preferably a region of 16 mm or less from the boundary between the cooling section 20 and the substrate 10, more preferably a region of 15.5 mm or less, even more preferably a region of 15 mm or less, and particularly preferably a region of 14.5 mm or less.
 貫通孔60は、自動喫煙機で17.5ml/秒で吸引した時の貫通孔60からの空気流入割合が10体積%以上90体積%以下となるように設ける。この「空気流入割合」は、吸口端から吸引した空気の割合を100体積%とした場合における貫通孔60から流入した空気の体積割合である。空気流入割合は、50体積%以上80体積%以下であることが好ましく、55体積%以上75体積%以下であることがより好ましい。これらの空気流入割合は、例えば、貫通孔群1つ当たりの貫通孔60の数を5個以上50個以下の範囲から選択し、貫通孔60の直径を0.1mm以上0.5mm以下の範囲から選択し、これらの選択の組み合わせによって達成することができる。
 空気流入割合は、巻品質測定器(S.A.S社製造のSODIMAX D74/SODIM)を用い、ISO9512に準拠した方法で測定することができる。
The through holes 60 are provided so that the air inflow rate from the through holes 60 is 10% by volume or more and 90% by volume or less when inhaled at 17.5 ml/sec by an automatic smoking machine. This "air inflow rate" is the volumetric rate of air inflowing from the through holes 60 when the rate of air inhaled from the mouth end is 100% by volume. The air inflow rate is preferably 50% by volume or more and 80% by volume or less, and more preferably 55% by volume or more and 75% by volume or less. These air inflow rates can be achieved, for example, by selecting the number of through holes 60 per through hole group from the range of 5 to 50, selecting the diameter of the through holes 60 from the range of 0.1 mm to 0.5 mm, and combining these selections.
The air inflow ratio can be measured by a method conforming to ISO9512 using a winding quality measuring device (SODIMAX D74/SODIM manufactured by SAS).

The pulp may be made from wood pulp such as softwood pulp or hardwood pulp, or may be made by mixing non-wood pulp generally used in cigarette papers for tobacco articles, such as flax pulp, hemp pulp, sisal pulp, or esparto. These pulps may be used alone or in combination in any ratio.

The lip release material means a material configured to assist in the easy separation of the contact between the lips and the tipping paper 40 without substantial adhesion when the user holds the filter portion 30 of the flavor inhalation article 1 in the mouth. The lip release material may include, for example, ethyl cellulose, methyl cellulose, nitrocellulose, etc. For example, the outer surface of the tipping paper 40 may be coated with the lip release material by applying an ethyl cellulose-based or methyl cellulose-based ink to the outer surface of the tipping paper 40.
 以上、説明したように、香味吸引物品1は、少なくともエアロゾル源11を含む基材部10と、基材部10が加熱されることで生成された蒸気を冷却してエアロゾルを生成する冷却部20と、エアロゾルが通過するフィルタ部30と、基材部10と、冷却部20と、フィルタ部30との外周面に巻かれるチップペーパー40と、を備える。そして、フィルタ部30は、シート部材31aが充填されたペーパーフィルタであるフィルタ31と、フィルタ31に配置された物体33を有し、物体33は物体33が配置されていない位置のペーパーフィルタ(フィルタ31)よりも硬い。ペーパーフィルタは通常の酢酸セルロース等の繊維を用いたフィルタよりも柔らかく、ペーパーフィルタを使用するとフィルタ部30が通常より柔らかくなる。それを解決するため、物体33が配置されていない位置のペーパーフィルタ(フィルタ31)よりも硬い物体33を使用すると、フィルタ部30に所望の硬さを付与することができる。その結果として、フィルタ部30の咥え心地やフィルタ部30を手に持った時の硬さ等の感触、更にはフィルタ部30をある程度硬くすることにより香味吸引物品1が非燃焼加熱型である場合に吸引装置100への香味吸引物品1の装着し易さを向上させることができる。なお、香味吸引物品1は、中心線方向の大きさのコンパクト化の観点から、冷却部20を有さなくてもよい。 As described above, the flavor inhalation article 1 includes a substrate 10 including at least an aerosol source 11, a cooling section 20 for generating an aerosol by cooling the steam generated by heating the substrate 10, and a filter section 30 through which the aerosol passes, and a tipping paper 40 wound around the outer peripheral surface of the substrate 10, the cooling section 20, and the filter section 30. The filter section 30 includes a filter 31, which is a paper filter filled with a sheet member 31a, and an object 33 placed on the filter 31, and the object 33 is harder than the paper filter (filter 31) at a position where the object 33 is not placed. The paper filter is softer than a filter using fibers such as ordinary cellulose acetate, and when a paper filter is used, the filter section 30 becomes softer than usual. To solve this problem, the object 33 harder than the paper filter (filter 31) at a position where the object 33 is not placed can be used to impart a desired hardness to the filter section 30. As a result, the feel of the filter part 30 in the mouth and the hardness when held in the hand can be improved, and further, by making the filter part 30 somewhat hard, the ease of attaching the flavor inhalation article 1 to the inhalation device 100 can be improved when the flavor inhalation article 1 is a non-combustion heating type. Note that the flavor inhalation article 1 does not need to have a cooling part 20 from the viewpoint of compact size in the center line direction.
<第2実施形態>
 図11は、第2実施形態に係る香味吸引物品2の縦断面を示す図であり、(A)は物体33がフィルタ31内の第1側に位置する状態、(B)は物体33がフィルタ31内の第2側に位置する状態を示す図である。
 第2実施形態に係る香味吸引物品2は、第1実施形態に係る香味吸引物品1に対して、フィルタ部30に相当するフィルタ部230が異なる。以下、第1実施形態と異なる点について説明する。第1実施形態と第2実施形態とで、同じものについては同じ符号を用い、その詳細な説明は省略する。
Second Embodiment
Figure 11 is a diagram showing a longitudinal section of the flavor inhalation article 2 according to the second embodiment, in which (A) shows a state in which the object 33 is located on a first side within the filter 31, and (B) shows a state in which the object 33 is located on a second side within the filter 31.
The flavor inhalation article 2 according to the second embodiment is different from the flavor inhalation article 1 according to the first embodiment in that it has a filter section 230 corresponding to the filter section 30. The differences from the first embodiment will be described below. The same components in the first and second embodiments are designated by the same reference numerals, and detailed descriptions thereof will be omitted.
 フィルタ部230は、ペーパーフィルタであるフィルタ31と、フィルタ31とは別個の独立したフィルタである別フィルタ32と、フィルタ31の物体が配置されていない位置よりも硬い物体33と、フィルタ31とチップペーパー40との間に存在してフィルタ31の外周面に巻かれる巻取紙35とを有している。フィルタ部230は、チップペーパー40を用いて、冷却部20とフィルタ部230とが一体に巻き取られることで、冷却部20と接続(連結)される。なお、フィルタ31と別フィルタ32はそれぞれ別の巻取紙35により巻かれた後、更に別の巻取紙35により合わせて巻かれることが好ましい。 The filter section 230 has a filter 31 which is a paper filter, a separate filter 32 which is an independent filter separate from the filter 31, an object 33 which is harder than a position of the filter 31 where no object is placed, and a wrapping paper 35 which is between the filter 31 and the tipping paper 40 and which is wrapped around the outer periphery of the filter 31. The filter section 230 is connected (linked) to the cooling section 20 by winding the cooling section 20 and the filter section 230 together using the tipping paper 40. It is preferable that the filter 31 and the separate filter 32 are each wound with a separate wrapping paper 35, and then wound together with yet another wrapping paper 35.
 フィルタ部230の別フィルタ32の横断面は実質的に円形であり、その円周は、製品のサイズに合わせて適宜変更し得るが、22mm以上27mm以下を挙げることができる。なお、横断面が円形でない場合、上記の円周は、その断面の面積と同じ面積を有する円で仮定し、その円における円周が適用される。
 フィルタ部230の通気抵抗及び中心線方向の大きさは、フィルタ部30の通気抵抗及び中心線方向の大きさと同一であることを例示することができる。フィルタ部230の形状や寸法が上記範囲となるように、フィルタ31、別フィルタ32の形状や寸法を適宜調整できる。
The cross section of the separate filter 32 of the filter unit 230 is substantially circular, and the circumference can be changed appropriately according to the size of the product, but can be 22 mm or more and 27 mm or less. If the cross section is not circular, the circumference is assumed to be a circle having the same area as the cross section, and the circumference of that circle is applied.
For example, the airflow resistance and the size in the center line direction of the filter unit 230 may be the same as the airflow resistance and the size in the center line direction of the filter unit 30. The shapes and dimensions of the filter 31 and the separate filter 32 can be appropriately adjusted so that the shape and dimensions of the filter unit 230 are within the above ranges.
 別フィルタ32は、フィルタ材を含み、フィルタの一般的な機能を有していれば特に制限されない。フィルタ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、エアロゾル源11の充填率が低くなる傾向のある非燃焼加熱型香味吸引物品2においては、ろ過機能を抑えつつエアロゾル源11の脱落を防止する、ということも重要な機能の一つである。なお、別フィルタ32は、フィルタ31よりもろ過率が低く、フィルタ31よりも硬度が高いものでもよい。 The separate filter 32 is not particularly limited as long as it contains a filter material and has the general functions of a filter. Examples of the general functions of a filter include adjusting the amount of air mixed in when inhaling aerosols, reducing flavors, and reducing nicotine and tar, but it is not necessary for the filter to have all of these functions. In addition, in the non-combustion heating type flavor inhalation article 2, which tends to generate fewer components and has a lower filling rate of the aerosol source 11 compared to cigarette products, one of the important functions is to prevent the aerosol source 11 from falling off while suppressing the filtering function. The separate filter 32 may have a lower filtering rate and a higher hardness than the filter 31.
 別フィルタ32を構成するフィルタ材は、例えば、酢酸セルロース繊維や不織布、パルプ紙等の充填物を円柱状に成形したものである。また、シート状のパルプ紙を充填したペーパーフィルタを用いる態様でもよい。また、これらの充填物に加えて、活性炭、セピオライト、パリゴルスカイト、ゼオライト、活性炭素繊維、活性アルミナ、セピオライト混合紙、シリカゲル、活性白土、バーミキュライト、珪藻土等の無機物吸着剤、パルプ、各種繊維、イオン交換樹脂等の高分子多孔質体を用いることができる。
 別フィルタ32を構成するフィルタ材の充填密度は、特段制限されないが、通常90mg/cm以上360mg/cm以下であり、150mg/cm以上240mg/cm以下であることが好ましい。
The filter material constituting the separate filter 32 is, for example, a cylindrically shaped filler such as cellulose acetate fiber, nonwoven fabric, or pulp paper. Alternatively, a paper filter filled with sheet-shaped pulp paper may be used. In addition to these fillers, inorganic adsorbents such as activated carbon, sepiolite, palygorskite, zeolite, activated carbon fiber, activated alumina, sepiolite mixed paper, silica gel, activated clay, vermiculite, and diatomaceous earth, pulp, various fibers, and polymeric porous bodies such as ion exchange resins may be used.
The packing density of the filter material constituting the separate filter 32 is not particularly limited, but is usually 90 mg/cm 3 or more and 360 mg/cm 3 or less, and preferably 150 mg/cm 3 or more and 240 mg/cm 3 or less.
 図11(A)に示す例では、フィルタ部230は、冷却部20の第2側に接続された別フィルタ32と、別フィルタ32の第2側に位置するフィルタ31とを有している。換言すると、フィルタ部230には、上流側に別フィルタ32が位置し、下流側にフィルタ31が位置している。フィルタ31内の第1側(基材部10側)に、フィルタ31の中心線方向の大きさよりも小さく中実の物体33が配置されている。具体的には、フィルタ31内の上流側の領域に、物体33が配置されている。 In the example shown in FIG. 11(A), the filter section 230 has a separate filter 32 connected to the second side of the cooling section 20, and a filter 31 located on the second side of the separate filter 32. In other words, in the filter section 230, the separate filter 32 is located on the upstream side, and the filter 31 is located on the downstream side. A solid object 33 that is smaller than the size of the filter 31 in the center line direction is disposed on the first side (the substrate section 10 side) within the filter 31. Specifically, the object 33 is disposed in the upstream region within the filter 31.
 図11(B)に示すように、フィルタ31内の第2側(下流側)に、フィルタ31の中心線方向の大きさよりも小さく中実の物体33が配置されてもよい。具体的には、フィルタ31内の第2側の領域に、物体33が配置されてもよい。物体33がフィルタ31内の第2側に位置する場合、物体33の第2側の端面がフィルタ31の第2側の端面から2mm以上離れていることが好ましい。 As shown in FIG. 11(B), a solid object 33 smaller than the size of the filter 31 in the center line direction may be disposed on the second side (downstream side) of the filter 31. Specifically, the object 33 may be disposed in the second side region of the filter 31. When the object 33 is located on the second side of the filter 31, it is preferable that the end face of the object 33 on the second side is 2 mm or more away from the end face of the filter 31 on the second side.
 フィルタ部230の構成は、図11(A),(B)に示す例に限定されず、フィルタ31と別フィルタ32との位置関係が変更されてもよい。また、物体33は中空部材でもよい。
 図12は、第2実施形態に係る香味吸引物品2の縦断面の他の例を示す図であり、(A)は物体33がフィルタ31内の第1側に位置する状態、(B)は物体33がフィルタ31内の第2側に位置する状態を示す図である。
11A and 11B, the positional relationship between the filter 31 and the separate filter 32 may be changed. Also, the object 33 may be a hollow member.
Figure 12 is a diagram showing another example of a longitudinal section of the flavor inhalation article 2 according to the second embodiment, in which (A) shows a state in which the object 33 is located on a first side within the filter 31, and (B) shows a state in which the object 33 is located on a second side within the filter 31.
 フィルタ部230は、冷却部20の第2側に接続されたフィルタ31と、フィルタ31の第2側に位置する別フィルタ32とを有してもよい。換言すると、フィルタ部230には、上流側にフィルタ31が位置し、下流側に別フィルタ32が位置してもよい。
 フィルタ31の中心線方向の大きさよりも小さく中実の物体33が、図12(A)に示すように、フィルタ31内の第1側(基材部10側)に配置されてもよく、図12(B)に示すように、フィルタ31内の第2側(下流側)に配置されてもよい。具体的には、フィルタ31内の第2側の領域に、物体33が配置されてもよい。また、物体33は中空部材でもよい。
The filter section 230 may have a filter 31 connected to the second side of the cooling section 20, and another filter 32 located on the second side of the filter 31. In other words, in the filter section 230, the filter 31 may be located on the upstream side, and the another filter 32 may be located on the downstream side.
A solid object 33 smaller than the size of the filter 31 in the center line direction may be disposed on a first side (substrate portion 10 side) in the filter 31 as shown in Fig. 12(A) or on a second side (downstream side) in the filter 31 as shown in Fig. 12(B). Specifically, the object 33 may be disposed in the second side region in the filter 31. The object 33 may also be a hollow member.
 以上、説明したように、第2実施形態に係る香味吸引物品2のフィルタ部230は、ペーパーフィルタであるフィルタ31と、フィルタ31とは別個の独立したフィルタである別フィルタ32と、物体33が配置されていない位置のフィルタ31よりも硬い物体33とを有する。フィルタ31の他に別フィルタ32が存在することで、フィルタ部230のろ過機能を多様化させることができる。別フィルタ32よりも硬度が低いフィルタ31に物体33が存在することで、ユーザが咥える領域の強度を高めることができる。また、手に持った感触を向上すること、及び、香味吸引物品1が非燃焼加熱型である場合に吸引装置100への香味吸引物品1の装着し易さを向上させることができる。
 なお、上述した例では、フィルタ部230は、ペーパーフィルタであるフィルタ31に加え、別フィルタ32を有するデュアル構造だがこれに限られない。フィルタ部230は、ペーパーフィルタであるフィルタ31に加え、2種類以上のフィルタを有してもよい。
As described above, the filter section 230 of the flavor inhalation article 2 according to the second embodiment has the filter 31 which is a paper filter, the separate filter 32 which is an independent filter separate from the filter 31, and the object 33 which is harder than the filter 31 at a position where the object 33 is not placed. The presence of the separate filter 32 in addition to the filter 31 can diversify the filtering function of the filter section 230. The presence of the object 33 in the filter 31 which is lower in hardness than the separate filter 32 can increase the strength of the area held by the user. In addition, the feel of holding in the hand can be improved, and the ease of mounting the flavor inhalation article 1 to the inhalation device 100 can be improved when the flavor inhalation article 1 is of a non-combustion heating type.
In the above example, the filter unit 230 has a dual structure including the filter 31, which is a paper filter, and the separate filter 32, but is not limited to this. The filter unit 230 may have two or more types of filters in addition to the filter 31, which is a paper filter.
<第3実施形態>
 図13は、第3実施形態に係る香味吸引物品3の縦断面を示す図であり、(A)は物体33がエアロゾル改質剤34の第1側に位置する状態、(B)は物体33がエアロゾル改質剤34の第2側に位置する状態を示す図である。
 第3実施形態に係る香味吸引物品3は、第1実施形態に係る香味吸引物品1に対して、フィルタ部30に相当するフィルタ部330が異なる。以下、第1実施形態と異なる点について説明する。第1実施形態と第3実施形態とで、同じものについては同じ符号を用い、その詳細な説明は省略する。
Third Embodiment
Figure 13 is a diagram showing a longitudinal section of the flavor inhalation article 3 relating to the third embodiment, in which (A) shows a state in which the object 33 is located on the first side of the aerosol modifier 34, and (B) shows a state in which the object 33 is located on the second side of the aerosol modifier 34.
The flavor inhalation article 3 according to the third embodiment is different from the flavor inhalation article 1 according to the first embodiment in that the filter portion 330 corresponds to the filter portion 30. The differences from the first embodiment will be described below. The same components in the first and third embodiments are designated by the same reference numerals, and detailed descriptions thereof will be omitted.
 フィルタ部330は、ペーパーフィルタであるフィルタ31と、フィルタ31のろ過率よりも低いろ過率であり、中実である物体33と、エアロゾルを改質するエアロゾル改質剤34と、フィルタ31とチップペーパー40との間に存在してフィルタ31の外周面に巻かれる巻取紙35とを有している。フィルタ部330は、チップペーパー40を用いて、冷却部20とフィルタ部330とが一体に巻き取られることで、冷却部20と接続(連結)される。なお、巻取紙35は有さなくてもよい。 The filter section 330 has a filter 31 which is a paper filter, a solid object 33 which has a lower filtering rate than that of the filter 31, an aerosol modifier 34 which modifies the aerosol, and a winding paper 35 which is present between the filter 31 and the tipping paper 40 and which is wound around the outer periphery of the filter 31. The filter section 330 is connected (joined) to the cooling section 20 by winding the cooling section 20 and the filter section 330 together using the tipping paper 40. The winding paper 35 does not necessarily have to be provided.
 エアロゾル改質剤34は、フィルタ部330の内部に配置されるものである。エアロゾル改質剤34は、エアロゾル改質剤34が配置されていない位置のフィルタ31よりも硬い場合は、第2の物体となり、フィルタ部330の咥え心地や使用感等を向上させることができる。
 エアロゾル改質剤34は、フィルタ部330の縦断面における位置は特段制限しないが、物体33と中心線方向の直線状に配置されていることが好ましい。換言すると、エアロゾル改質剤34は、物体33とフィルタ部330の長手方向の直線状に配置されていることが好ましい。
 具体的には、エアロゾル改質剤34は、物体33を通過したエアロゾルが通過する位置や、エアロゾル改質剤34にぶつかったエアロゾルが物体33を通過するような位置等の物体33と対応する位置に配置されていることが好ましい。エアロゾル改質剤34が物体33と対応する位置に配置されることで、改質されたエアロゾルのデリバリー効率を向上させることができる。また、エアロゾル改質剤34が配置されることによりフィルタ部330の強度を高め、咥え心地や使用感等を向上させることができる。
The aerosol modifier 34 is disposed inside the filter portion 330. When the aerosol modifier 34 is harder than the filter 31 at a position where the aerosol modifier 34 is not disposed, the aerosol modifier 34 becomes a second object, and can improve the fit and usability of the filter portion 330.
Although there are no particular limitations on the position of the aerosol modifier 34 in the vertical cross section of the filter section 330, it is preferable that the aerosol modifier 34 is arranged in a straight line in the center line direction with the object 33. In other words, it is preferable that the aerosol modifier 34 is arranged in a straight line in the longitudinal direction of the object 33 and the filter section 330.
Specifically, the aerosol modifier 34 is preferably disposed at a position corresponding to the object 33, such as a position through which the aerosol that has passed through the object 33 passes, or a position through which the aerosol that has collided with the aerosol modifier 34 passes through the object 33. By disposing the aerosol modifier 34 at a position corresponding to the object 33, it is possible to improve the delivery efficiency of the modified aerosol. Furthermore, by disposing the aerosol modifier 34, it is possible to increase the strength of the filter portion 330 and improve the comfort of holding it in the mouth and the feeling of use, etc.
 図13(A)に示す例では、フィルタ部330は、物体33に対して第2側(下流側)であって、物体33と中心線方向の直線状に配置されたエアロゾル改質剤34を有している。エアロゾル改質剤34が、物体33に対して第2側(吸口端側)であってフィルタ部330の長手方向の直線状に配置されていることで、吸引時に、物体33を通過したエアロゾルを、エアロゾル改質剤34に効率的に接触させることができる。また、エアロゾルが効率的にエアロゾル改質剤34と接触することで、エアロゾルの改質効果を向上させることができる。 In the example shown in FIG. 13(A), the filter section 330 has an aerosol modifier 34 that is on the second side (downstream side) of the object 33 and is arranged in a straight line with the object 33 in the center line direction. By arranging the aerosol modifier 34 on the second side (suction port end side) of the object 33 and in a straight line in the longitudinal direction of the filter section 330, the aerosol that has passed through the object 33 during inhalation can be efficiently brought into contact with the aerosol modifier 34. Furthermore, by efficiently bringing the aerosol into contact with the aerosol modifier 34, the modification effect of the aerosol can be improved.
 また、図13(B)に示すように、フィルタ部330は、物体33に対して第1側(上流側)であって、物体33と中心線方向の直線状に配置されたエアロゾル改質剤34を有してもよい。エアロゾル改質剤34が、物体33に対して第1側(基材部10側)であってフィルタ部330の長手方向の直線状に配置されていることで、吸引時に、改質されたエアロゾルを物体33に通過させることができる。また、フィルタ部330にてエアロゾル改質剤34が第1側(上流側)の領域に配置されることで、十分にろ過される前のエアロゾルをエアロゾル改質剤34と接触させ、エアロゾルの改質効果を向上させることができる。 Also, as shown in FIG. 13(B), the filter section 330 may have an aerosol modifier 34 arranged on the first side (upstream side) with respect to the object 33, in a straight line with the object 33 in the center line direction. By arranging the aerosol modifier 34 on the first side (substrate section 10 side) with respect to the object 33 and in a straight line in the longitudinal direction of the filter section 330, the modified aerosol can be passed through the object 33 during inhalation. Furthermore, by arranging the aerosol modifier 34 in the first side (upstream side) region of the filter section 330, the aerosol before being sufficiently filtered can be brought into contact with the aerosol modifier 34, improving the modification effect of the aerosol.
 エアロゾル改質剤34は、例えば、外力を加えることで香料成分を含む内容物が放出される破壊性カプセルである。
 エアロゾル改質剤34は、フィルタ31の第1側の端面及び第2側の端面から内容物が漏れ出さない位置に埋め込まれることが好ましい。換言すると、エアロゾル改質剤34は、内容物の拡散がフィルタ部330で納まる位置に配置されることが好ましい。
 エアロゾル改質剤34は、呈味成分と香料成分とのうち少なくとも何れか一方を含む内容物と、内容物を保持するカプセル本体とを含む。エアロゾル改質剤34は、ユーザによって潰されることで、カプセル本体が破壊され、その中の内容物が放出される。潰すとは、例えば、巻取紙35及びチップペーパー40を親指と人差し指とで押すことで破壊性カプセルであるエアロゾル改質剤34を加圧することである。
The aerosol modifier 34 is, for example, a destructible capsule that releases its contents, including a flavor component, when an external force is applied.
The aerosol modifying agent 34 is preferably embedded in a position where the contents do not leak out from the first end face and the second end face of the filter 31. In other words, the aerosol modifying agent 34 is preferably disposed in a position where the diffusion of the contents is contained within the filter portion 330.
The aerosol modifier 34 includes a content containing at least one of a taste component and a flavor component, and a capsule body that holds the content. When the aerosol modifier 34 is crushed by a user, the capsule body is broken and the content therein is released. To crush means, for example, to pressurize the aerosol modifier 34, which is a breakable capsule, by pressing the wrapping paper 35 and the tipping paper 40 with the thumb and index finger.
 呈味成分としては、クエン酸、酒石酸、グルタミン酸ナトリウム、ネオテーム、ソーマチン、ステビア、ソルビトール、キシリトール、エリスリトール、アスパルテーム、ルチン、ヘスペリジン、シュウ酸、タンニン酸、カテキン、ナリンジン、キニーネ、キナ酸、リモニン、カフェイン、カプサイシン、ビタミン類、アミノ酸類、ポリフェノール類、アルギン酸、フラボノイド、レシチン等が挙げられる。呈味成分は、液体もしくは口腔内で実質的に溶解可能であることが好ましい。
 香料成分としては、特に限定されず、例えば、粉末香料、油性香料等が挙げられる。主な粉末香料としては、カモミール、フェヌグリーク、メンソール、ハッカ、シナモン、ハーブ等を粉末にしたものが挙げられる。また、主な油性香料としては、ラベンダー、シナモン、カルダモン、セレリー、チョウジ、カスカリラ、ナツメグ、サンダルウッド、ベルガモット、ゼラニウム、ハチミツエッセンス、ローズ油、バニラ、レモン、オレンジ、ハッカ、ケイ皮、キャラウエー、コニャック、ジャスミン、カモミール、メントール、カシヤ、イランイラン、セージ、スペアミント、フェンネル、ピメント、ジンジャー、アニス、コリアンダ、コーヒー、たばこ等が挙げられる。香料成分は1種を単独で、又は2種以上を併用してもよい。粉末香料を用いる場合、その粒径は500μm以下であることが好ましい。香料成分は、液体もしくは口腔内で実質的に溶解可能であることが好ましい。
Examples of flavor components include citric acid, tartaric acid, sodium glutamate, neotame, thaumatin, stevia, sorbitol, xylitol, erythritol, aspartame, rutin, hesperidin, oxalic acid, tannic acid, catechin, naringin, quinine, quinic acid, limonin, caffeine, capsaicin, vitamins, amino acids, polyphenols, alginic acid, flavonoids, lecithin, etc. The flavor component is preferably substantially soluble in liquid or in the oral cavity.
The flavoring component is not particularly limited, and examples thereof include powdered flavorings and oil-based flavorings. Major powdered flavorings include powdered chamomile, fenugreek, menthol, peppermint, cinnamon, herbs, and the like. Major oil-based flavorings include lavender, cinnamon, cardamom, celery, clove, cascarilla, nutmeg, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon, orange, peppermint, cinnamon bark, caraway, cognac, jasmine, chamomile, menthol, cassia, ylang-ylang, sage, spearmint, fennel, pimento, ginger, anise, coriander, coffee, tobacco, and the like. The flavoring components may be used alone or in combination of two or more. When using a powdered flavoring, the particle size is preferably 500 μm or less. It is preferable that the flavoring component is substantially soluble in a liquid or in the oral cavity.
 内容物は、呈味成分と香料成分とのうち少なくとも何れか一方に加えて、合成着色料、天然着色料等の着色料を含んでもよい。着色料は、赤色3,106号、ベータカロテン、銅クロロフィリン、クチナシ青色素、黄色4号等の食品添加物が好ましい。
 内容物は、呈味成分、香料成分、及び着色料を溶解する溶媒をさらに含んでもよい。溶媒としては、例えば、中鎖脂肪酸トリグリセリド、グリセリン、プロピレングリコール、水、エタノール等を挙げることができる。
 内容物が液体又はゲル状である場合には、フィルタ31及び巻取紙35に浸透するため、その粘度は20mPa・s以上であり、30mPa・s以上であることが好ましい。また、内容物の粘度は120mPa・s以下であり、90mPa・s以下であることが好ましい。内容物の粘度が上記の下限以上であることで、内容物が香味吸引物品3内に広がり、エアロゾルに新たな香喫味を付与することができる。また、内容物の粘度が上記の上限以下であることで、フィルタ31及び巻取紙35に内容物が浸透する速度が速すぎて、香味吸引物品3を使用する際に浸透した内容物が香味吸引物品3の外側まで染み出すことを防ぐことができる。
 また、フィルタ31の横断面の面積当たりの内容物の液体量が0.2μl/mm未満である場合、フィルタ31内に十分に浸透しないおそれがある。一方で、フィルタ31の横断面の面積当たりの内容物の液体量が2.2μl/mmよりも多い場合、内容物が香味吸引物品3の第2側の端面に到達してユーザに付着するおそれがある。そのため、フィルタ31の横断面の面積当たりの内容物の液体量は0.2μl/mm以上2.2μl/mm以下であり、0.3μl/mm以上0.7μl/mm以下であることが好ましい。
The contents may contain, in addition to at least one of the flavoring component and the flavoring component, a coloring agent such as a synthetic coloring agent, a natural coloring agent, etc. The coloring agent is preferably a food additive such as Red No. 3,106, beta-carotene, copper chlorophyllin, gardenia blue pigment, Yellow No. 4, etc.
The contents may further contain a solvent for dissolving the flavoring component, the flavoring component, and the coloring agent. Examples of the solvent include medium-chain fatty acid triglyceride, glycerin, propylene glycol, water, and ethanol.
When the contents are liquid or gel-like, the viscosity of the contents is 20 mPa·s or more, preferably 30 mPa·s or more, in order to permeate the filter 31 and the roll paper 35. The viscosity of the contents is 120 mPa·s or less, preferably 90 mPa·s or less. When the viscosity of the contents is equal to or more than the above lower limit, the contents spread within the flavor inhalation article 3, and a new flavor can be imparted to the aerosol. When the viscosity of the contents is equal to or less than the above upper limit, the speed at which the contents permeate the filter 31 and the roll paper 35 is too fast, and the permeated contents can be prevented from seeping out of the flavor inhalation article 3 when the flavor inhalation article 3 is used.
Furthermore, when the amount of liquid of the contents per cross-sectional area of the filter 31 is less than 0.2 μl/ mm2 , the contents may not sufficiently penetrate into the filter 31. On the other hand, when the amount of liquid of the contents per cross-sectional area of the filter 31 is more than 2.2 μl/ mm2 , the contents may reach the end face on the second side of the flavor inhalation article 3 and adhere to the user. Therefore, the amount of liquid of the contents per cross-sectional area of the filter 31 is 0.2 μl/ mm2 or more and 2.2 μl/ mm2 or less, and preferably 0.3 μl/mm2 or more and 0.7 μl/ mm2 or less.
 カプセル本体の材料としては、例えば、デンプン、デキストリン、多糖類、寒天、ジェランガム、ゼラチン、ポリ塩化ビニル、ポリ塩化ビニリデン、ポリスチレン、スチレン・アクリロニトリル共重合体、スチレン・ブタジエン・アクリロニトリル共重合体、ポリエチレン、ポリプロピレン、酢酸セルロース、ポリエチレンテレフタレート、ポリアミド、エチレン‐アクリル酸プラスチック、エチレン‐酢酸ビニルプラスチック、エチレン‐ビニルアルコールプラスチック、各種天然ゲル化剤等が挙げられる。カプセル本体は、上記材料に加えて、香料成分、可塑剤、着色料等を含むことができる。  Examples of materials for the capsule body include starch, dextrin, polysaccharides, agar, gellan gum, gelatin, polyvinyl chloride, polyvinylidene chloride, polystyrene, styrene-acrylonitrile copolymer, styrene-butadiene-acrylonitrile copolymer, polyethylene, polypropylene, cellulose acetate, polyethylene terephthalate, polyamide, ethylene-acrylic acid plastic, ethylene-vinyl acetate plastic, ethylene-vinyl alcohol plastic, various natural gelling agents, etc. In addition to the above materials, the capsule body can also contain fragrance components, plasticizers, colorants, etc.
 エアロゾル改質剤34が破壊性カプセルである場合、その形状は、特に制限されず、球形状、円柱形状、円錐台形状等であってよい。破壊性カプセルは、例えば、直径2.5mm以上4.0mm以下の球形状、中心線方向の大きさが5mm以上10mm以下かつ直径5mm以上7mm以下の円柱形状が挙げられる。また、複数の球形状の破壊性カプセルを配置する場合には、破壊性カプセルは直径3.5mm以下であることが好ましい。
 破壊性カプセルの製造方法は、特に制限されないが、例えば、継ぎ目のないシームレスなカプセル本体を有する破壊性カプセルを製造可能な滴下法を用いることが好ましい。
When the aerosol modifier 34 is a destructible capsule, its shape is not particularly limited and may be spherical, cylindrical, truncated cone, etc. Examples of the destructible capsule include a spherical shape with a diameter of 2.5 mm to 4.0 mm, and a cylindrical shape with a size in the center line direction of 5 mm to 10 mm and a diameter of 5 mm to 7 mm. Furthermore, when multiple spherical destructible capsules are arranged, it is preferable that the destructible capsules have a diameter of 3.5 mm or less.
The method for producing the breakable capsules is not particularly limited, but it is preferable to use, for example, a dropping method which can produce a breakable capsule having a seamless capsule body.
 エアロゾル改質剤34は、外力を加えることで香料成分を含む内容物が放出される破壊性カプセルとしたが、エアロゾルを改質するものであればこれに限られない。
 例えば、エアロゾル改質剤34は、基材部10の加熱により生成される物質を吸着させ除去させる機能を有する吸着剤であってもよい。吸着剤としては、特に限定されず、活性炭、セピオライト、パリゴルスカイト、ゼオライト、活性炭素繊維、活性アルミナ、セピオライト混合紙、シリカゲル、活性白土、バーミキュライト、珪藻土、イオン交換樹脂等を挙げることができる。エアロゾル改質剤34として、顆粒の吸着剤がフィルタ31に添加されてもよいし、例えば直径2.5mm以上4.0mm以下の球形状に造粒した吸着剤がフィルタ31に配置されてもよい。
 その他、例えば、エアロゾル改質剤34は、水分や熱が加わることで香料成分が放出される香料担持物であってもよい。香料担持物としては、特に限定されず、デキストリン、サイクロデキストリン等の担体に香料成分を担持させたものを挙げることができる。エアロゾル改質剤34として、シート状の香料担持物がフィルタ31に配置されてもよいし、例えば直径2.5mm以上4.0mm以下の球形状に造粒した香料担持物がフィルタ31に配置されてもよい。
Although the aerosol modifier 34 is a destructible capsule that releases the contents including the flavoring component when an external force is applied, the present invention is not limited to this as long as it modifies the aerosol.
For example, the aerosol modifier 34 may be an adsorbent having a function of adsorbing and removing a substance generated by heating the base material 10. The adsorbent is not particularly limited, and examples thereof include activated carbon, sepiolite, palygorskite, zeolite, activated carbon fiber, activated alumina, sepiolite-mixed paper, silica gel, activated clay, vermiculite, diatomaceous earth, and ion exchange resin. As the aerosol modifier 34, a granular adsorbent may be added to the filter 31, or an adsorbent granulated into a spherical shape having a diameter of 2.5 mm or more and 4.0 mm or less may be placed in the filter 31.
Alternatively, for example, the aerosol modifier 34 may be a fragrance carrier that releases a fragrance component when moisture or heat is applied. The fragrance carrier is not particularly limited, and examples include carriers such as dextrin and cyclodextrin that carry a fragrance component. As the aerosol modifier 34, a sheet-shaped fragrance carrier may be disposed in the filter 31, or a fragrance carrier granulated into a spherical shape with a diameter of 2.5 mm to 4.0 mm may be disposed in the filter 31.
 以上、説明したように、第3実施形態に係る香味吸引物品3のフィルタ部330は、ペーパーフィルタであるフィルタ31と、物体33が配置されていない位置のフィルタ31よりも硬い硬度を有する物体33と、エアロゾルを改質するエアロゾル改質剤34とを有する。その結果、咥え心地や手に持った感触を向上させ、また、香味吸引物品3が非燃焼加熱型である場合に吸引装置100への香味吸引物品3の装着し易さを向上させることができる。フィルタ部330内にエアロゾル改質剤34を有することで、吸引時に、基材部10から発生するエアロゾルを改質することができる。また、エアロゾル改質剤34が外力を加えることで香料成分を含む内容液が放出される破壊性カプセルであることで、エアロゾルに新たな香喫味を付与することができる。 As described above, the filter section 330 of the flavor inhalation article 3 according to the third embodiment has the filter 31, which is a paper filter, the object 33, which has a harder hardness than the filter 31 at a position where the object 33 is not placed, and the aerosol modifier 34, which modifies the aerosol. As a result, the comfort of holding it in the mouth and in the hand can be improved, and when the flavor inhalation article 3 is of a non-combustion heating type, the ease of attaching the flavor inhalation article 3 to the inhalation device 100 can be improved. By having the aerosol modifier 34 in the filter section 330, the aerosol generated from the base section 10 during inhalation can be modified. In addition, since the aerosol modifier 34 is a destructible capsule that releases a content liquid containing a flavor component when an external force is applied, a new flavor and smoking taste can be imparted to the aerosol.
<第4実施形態>
 図14は、第4実施形態に係る香味吸引物品4の縦断面を示す図である。
 第4実施形態に係る香味吸引物品4は、第1実施形態に係る香味吸引物品1に対して、使用形態が異なる。また、第4実施形態に係る香味吸引物品4は、第1実施形態に係る香味吸引物品1に対して、マウスピースセグメント50に相当するマウスピース部450と、貫通孔60に相当する連通孔460とが異なる。以下、第1実施形態と異なる点について説明する。第1実施形態と第4実施形態とで、同じものについては同じ符号を用い、その詳細な説明は省略する。
Fourth Embodiment
FIG. 14 is a diagram showing a vertical cross section of the flavor inhalation article 4 according to the fourth embodiment.
The flavor inhalation article 4 according to the fourth embodiment has a different mode of use from the flavor inhalation article 1 according to the first embodiment. Also, the flavor inhalation article 4 according to the fourth embodiment is different from the flavor inhalation article 1 according to the first embodiment in a mouthpiece portion 450 corresponding to the mouthpiece segment 50 and a communication hole 460 corresponding to the through hole 60. The points that differ from the first embodiment will be described below. The same reference numerals are used for the same parts in the first embodiment and the fourth embodiment, and detailed descriptions thereof will be omitted.
 香味吸引物品4は、燃焼型の香味吸引物品である。ユーザが吸引のために口で咥える端部側である第2側と反対側である第1側の端面を燃焼させて使用される。基材部10に含まれるエアロゾル源11は、エアロゾルが生成される蒸気を、燃焼に伴う加熱によって生じさせる。
 香味吸引物品4の横断面は実質的に円形であり、その円周は、製品のサイズに合わせて適宜変更し得るが、通常16mm以上27mm以下であり、22mm以上25mm以下であることが好ましい。なお、横断面が円形でない場合、上記の円周は、その断面の面積と同じ面積を有する円で仮定し、その円における円周が適用される。
 香味吸引物品4の中心線方向の大きさは、製品のサイズに合わせて適宜変更し得るが、通常60mm以上120mm以下であり、80mm以上100mm以下であることが好ましい。
The flavor inhalation article 4 is a combustion-type flavor inhalation article. It is used by burning an end face of a first side, which is opposite to a second side, which is an end side that a user holds in his mouth for inhalation. The aerosol source 11 included in the base unit 10 generates steam from which an aerosol is generated by heating associated with combustion.
The cross section of the flavor inhalation article 4 is substantially circular, and the circumference thereof may be appropriately changed according to the size of the product, but is usually 16 mm to 27 mm, and preferably 22 mm to 25 mm. When the cross section is not circular, the circumference is assumed to be a circle having the same area as the cross section, and the circumference of the circle is applied.
The size of the flavor inhalation article 4 in the center line direction can be appropriately changed according to the size of the product, but is usually 60 mm or more and 120 mm or less, and preferably 80 mm or more and 100 mm or less.
 マウスピース部450は、フィルタ部30から構成される。
 マウスピース部450の中心線方向の大きさは、製品のサイズに合わせて適宜変更し得るが、通常20mm以上40mm以下であり、25mm以上30mm以下であることが好ましい。
 また、マウスピース部450には、その周方向に、かつ、同心状に複数の連通孔460が設けられている。連通孔460は、チップペーパー40に設けられた通気孔から流入された空気をフィルタ31内の空隙に連通させる孔である。連通孔460から流入される空気の量を調整することで、ユーザが吸引するエアロゾルの濃度を調整することができる。
The mouthpiece portion 450 is composed of a filter portion 30 .
The size of the mouthpiece portion 450 in the center line direction can be changed appropriately according to the size of the product, but is usually 20 mm or more and 40 mm or less, and preferably 25 mm or more and 30 mm or less.
Furthermore, the mouthpiece portion 450 is provided with a plurality of communication holes 460 arranged circumferentially and concentrically. The communication holes 460 are holes that allow air flowing in from an air hole provided in the tipping paper 40 to communicate with a gap in the filter 31. By adjusting the amount of air flowing in from the communication holes 460, the concentration of the aerosol inhaled by the user can be adjusted.
 また、マウスピース部450のフィルタ部30が、フィルタ31が巻取紙35及びチップペーパー40で巻装されてなる態様である場合、少なくとも巻取紙35には、チップペーパー40に設けられた通気孔と対応する位置に連通孔460が設けられていることが好ましい。このようなマウスピース部450を有する香味吸引物品4を作製する場合、連通孔460とチップペーパー40に設けられた通気孔とが重なるようにチップペーパー40を巻装してもよいが、製造容易性の観点から、連通孔460を有さない香味吸引物品4を作製した後、マウスピース部450及びチップペーパー40を同時に貫通する孔を開けることが好ましい。 In addition, when the filter section 30 of the mouthpiece section 450 is configured such that the filter 31 is wrapped with the wrapping paper 35 and the tipping paper 40, it is preferable that at least the wrapping paper 35 has a communication hole 460 at a position corresponding to the air hole provided in the tipping paper 40. When producing a flavor inhalation article 4 having such a mouthpiece section 450, the tipping paper 40 may be wrapped so that the communication hole 460 and the air hole provided in the tipping paper 40 overlap, but from the viewpoint of ease of production, it is preferable to produce a flavor inhalation article 4 that does not have a communication hole 460, and then open a hole that penetrates the mouthpiece section 450 and the tipping paper 40 at the same time.
 連通孔460が存在する領域は、空気の流入の効率を向上させる観点から、フィルタ31のうちのフィルタ31を構成するシート部材の充填密度が相対的に低い領域、換言すると、フィルタ31のうちの物体33が配置されていない領域であることが好ましい。
 図14に示す例では、フィルタ31の中心線方向の大きさよりも小さく中実である物体33がフィルタ31内の第1側(基材部10側)に位置し、連通孔460がフィルタ31のうちの物体33が配置されていない領域に設けられている。具体的には、連通孔460が物体33に対して下流側の領域に設けられている。
From the viewpoint of improving the efficiency of air inflow, it is preferable that the area in which the communication hole 460 exists is an area of the filter 31 in which the packing density of the sheet material constituting the filter 31 is relatively low, in other words, an area of the filter 31 in which no object 33 is positioned.
14 , the object 33, which is smaller than the size of the filter 31 in the center line direction and is solid, is located on the first side (the substrate portion 10 side) within the filter 31, and the communication hole 460 is provided in a region of the filter 31 where the object 33 is not located.
 連通孔460は、フィルタ31のうちの物体33が配置されていない領域に設けられていればよく、上述の構成に限られない。
 図15は、第4実施形態に係る香味吸引物品4の縦断面の他の例を示す図であり、物体33は中実であり、(A)は物体33がフィルタ31内の第2側に位置する状態、(B)は物体33がフィルタ31内の中央寄りに位置する状態、(C)は複数の物体33がフィルタ31内に位置する状態を示す図である。
The communication hole 460 is not limited to the above-mentioned configuration as long as it is provided in an area of the filter 31 where the object 33 is not placed.
Figure 15 is a diagram showing another example of a longitudinal section of the flavor inhalation article 4 according to the fourth embodiment, in which the object 33 is solid, (A) shows a state in which the object 33 is located on the second side within the filter 31, (B) shows a state in which the object 33 is located toward the center within the filter 31, and (C) shows a state in which multiple objects 33 are located within the filter 31.
 フィルタ31の中心線方向の大きさよりも小さい物体33がフィルタ31内の第2側(下流側)に位置する場合、図15(A)に示すように、連通孔460が物体33に対して上流側の領域に設けられてもよい。
 また、フィルタ31の中心線方向の大きさよりも小さい物体33が中心線方向においてフィルタ31内の中央寄りに位置する場合、図15(B)に示すように、連通孔460が物体33に対して上流側の領域に設けられてもよい。なお、連通孔460は、物体33に対して下流側の領域に設けられてもよい。
 また、フィルタ31内の複数の領域に物体33が配置されている場合、図15(C)に示すように、連通孔460がフィルタ31のうちの物体33が配置されていない領域に設けられてもよい。連通孔460は、物体33が配置されていない領域であれば、上流側、中央寄り、下流側の何れの領域に設けられてもよい。
When an object 33 smaller than the size of the filter 31 in the center line direction is located on the second side (downstream side) within the filter 31, a communication hole 460 may be provided in the upstream region of the object 33, as shown in Figure 15 (A).
15B , in a case where an object 33 smaller than the size of the filter 31 in the center line direction is located toward the center of the filter 31 in the center line direction, the communication hole 460 may be provided in a region upstream of the object 33. The communication hole 460 may also be provided in a region downstream of the object 33.
15C , in the case where objects 33 are disposed in a plurality of regions in the filter 31, the communication hole 460 may be provided in a region of the filter 31 in which no object 33 is disposed. The communication hole 460 may be provided in any region on the upstream side, near the center, or downstream side, so long as the region is one in which no object 33 is disposed.
 以上、説明したように、第4実施形態に係る香味吸引物品4は、少なくともエアロゾル源11を含む基材部10と、エアロゾルが通過するフィルタ部30と、基材部10とフィルタ部30との外周面に巻かれるチップペーパー40と、を備える。そして、フィルタ部30は、シート部材が充填されたペーパーフィルタであるフィルタ31と、フィルタ31に配置される物体33であって、物体33が配置されていない位置のフィルタ31よりも硬い物体33とを有する。物体33により、フィルタ部30の咥え心地や手に持った感触等を向上させることができる。また、物体33は中空部材でもよい。 As described above, the flavor inhalation article 4 according to the fourth embodiment includes a base member 10 including at least an aerosol source 11, a filter member 30 through which the aerosol passes, and tipping paper 40 wrapped around the outer peripheral surfaces of the base member 10 and the filter member 30. The filter member 30 has a filter 31 which is a paper filter filled with a sheet member, and an object 33 which is placed on the filter 31 and is harder than the filter 31 in a position where the object 33 is not placed. The object 33 can improve the comfort of the filter member 30 when held in the mouth or in the hand. The object 33 may also be a hollow member.
<第5実施形態>
 図16は、第5実施形態に係る香味吸引物品5の縦断面を示す図であり、物体33は中実であり、(A)は物体33がフィルタ31内の第1側に位置する状態、(B)は物体33がフィルタ31内の第2側に位置する状態を示す図である。
 第5実施形態に係る香味吸引物品5は、第4実施形態に係る香味吸引物品4に対して、フィルタ部30に相当するフィルタ部530が異なる。以下、第4実施形態と異なる点について説明する。第4実施形態と第5実施形態とで、同じものについては同じ符号を用い、その詳細な説明は省略する。
Fifth Embodiment
Figure 16 is a diagram showing a longitudinal section of a flavor inhalation article 5 according to the fifth embodiment, in which the object 33 is solid, and (A) shows a state in which the object 33 is located on a first side within the filter 31, and (B) shows a state in which the object 33 is located on a second side within the filter 31.
The flavor inhalation article 5 according to the fifth embodiment is different from the flavor inhalation article 4 according to the fourth embodiment in that the filter portion 530 corresponds to the filter portion 30. The differences from the fourth embodiment will be described below. The same reference numerals are used for the same parts in the fourth and fifth embodiments, and detailed descriptions thereof will be omitted.
 フィルタ部530は、ペーパーフィルタであるフィルタ31と、フィルタ31とは別個の独立したフィルタである別フィルタ32と、フィルタ31内に配置される物体33であって、物体33が配置されていない位置のフィルタ31より硬い物体33と、フィルタ31とチップペーパー40との間に存在してフィルタ31の外周面に巻かれる巻取紙35とを有している。フィルタ部530は、チップペーパー40を用いて、基材部10とフィルタ部530とが一体に巻き取られることで、基材部10と接続(連結)される。なお、フィルタ31と別フィルタ32はそれぞれ別の巻取紙35により巻かれた後、更に別の巻取紙35により合わせて巻かれることが好ましい。
 フィルタ部530の別フィルタ32の構成は、第2実施形態に係るフィルタ部230に含まれる別フィルタ32と同一であることを例示することができる。フィルタ部530の形状や寸法が上述した範囲となるように、フィルタ31、別フィルタ32の形状や寸法を適宜調整できる。
The filter section 530 has a filter 31 which is a paper filter, a separate filter 32 which is a filter separate and independent from the filter 31, an object 33 which is placed in the filter 31 and is harder than the filter 31 at a position where the object 33 is not placed, and a wrapping paper 35 which is present between the filter 31 and the tipping paper 40 and is wrapped around the outer circumferential surface of the filter 31. The filter section 530 is connected (coupled) to the base material section 10 by winding the base material section 10 and the filter section 530 together using the tipping paper 40. It is preferable that the filter 31 and the separate filter 32 are each wound with a separate wrapping paper 35, and then wound together with another wrapping paper 35.
The configuration of the separate filter 32 of the filter section 530 can be, for example, the same as the separate filter 32 included in the filter section 230 according to the second embodiment. The shapes and dimensions of the filter 31 and the separate filter 32 can be appropriately adjusted so that the shape and dimensions of the filter section 530 fall within the above-mentioned ranges.
 フィルタ部530は、基材部10の第2側に接続された別フィルタ32と、別フィルタ32の第2側に位置するフィルタ31とを有している。上流側に別フィルタ32が位置し、下流側にフィルタ31が位置している。図16(A)に示すように、フィルタ31内の第1側(上流側)に、フィルタ31の中心線方向の大きさよりも小さい物体33が配置され、連通孔460が物体33に対して下流側の領域に設けられてもよい。また、図16(B)に示すように、フィルタ31内の第2側(下流側)に、フィルタ31の中心線方向の大きさよりも小さい物体33が配置され、連通孔460が物体33に対して上流側の領域に設けられてもよい。 The filter section 530 has a separate filter 32 connected to the second side of the base section 10, and a filter 31 located on the second side of the separate filter 32. The separate filter 32 is located on the upstream side, and the filter 31 is located on the downstream side. As shown in FIG. 16(A), an object 33 smaller than the size of the filter 31 in the center line direction may be disposed on the first side (upstream side) of the filter 31, and a communication hole 460 may be provided in the downstream region of the object 33. Also, as shown in FIG. 16(B), an object 33 smaller than the size of the filter 31 in the center line direction may be disposed on the second side (downstream side) of the filter 31, and a communication hole 460 may be provided in the upstream region of the object 33.
 フィルタ部530の構成は、図16(A),(B)に示す例に限定されず、フィルタ31と別フィルタ32との位置関係が変更されてもよい。
 図17は、第5実施形態に係る香味吸引物品5の縦断面を示す図であり、物体33は中実であり、(A)は物体33がフィルタ31内の第1側に位置する状態、(B)は物体33がフィルタ31内の第2側に位置する状態を示す図である。
 フィルタ部530は、基材部10の第2側に接続されたフィルタ31と、フィルタ31の第2側に位置する別フィルタ32とを有している。上流側にフィルタ31が位置し、下流側に別フィルタ32が位置している。図17(A)に示すように、フィルタ31内の第1側(上流側)に、フィルタ31の中心線方向の大きさよりも小さい物体33が配置され、連通孔460が物体33に対して下流側の領域に設けられてもよい。また、図17(B)に示すように、フィルタ31内の第2側(下流側)に、フィルタ31の中心線方向の大きさよりも小さい物体33が配置され、連通孔460が物体33に対して上流側の領域に設けられてもよい。
The configuration of the filter unit 530 is not limited to the examples shown in FIGS. 16A and 16B, and the positional relationship between the filter 31 and the separate filter 32 may be changed.
Figure 17 is a diagram showing a longitudinal section of a flavor inhalation article 5 according to the fifth embodiment, in which the object 33 is solid, and (A) shows a state in which the object 33 is located on a first side within the filter 31, and (B) shows a state in which the object 33 is located on a second side within the filter 31.
The filter section 530 has a filter 31 connected to the second side of the base section 10 and another filter 32 located on the second side of the filter 31. The filter 31 is located on the upstream side, and the other filter 32 is located on the downstream side. As shown in FIG. 17A, an object 33 smaller than the size of the filter 31 in the center line direction may be disposed on the first side (upstream side) in the filter 31, and a communication hole 460 may be provided in a downstream region with respect to the object 33. Also, as shown in FIG. 17B, an object 33 smaller than the size of the filter 31 in the center line direction may be disposed on the second side (downstream side) in the filter 31, and a communication hole 460 may be provided in an upstream region with respect to the object 33.
 以上、説明したように、第5実施形態に係る香味吸引物品5のフィルタ部530は、ペーパーフィルタであるフィルタ31と、フィルタ31とは別個の独立したフィルタである別フィルタ32と、フィルタ31内に配置される物体33であって、物体33が配置されていない位置のフィルタ31より硬い物体33とを有する。なお、上述した例では、フィルタ部530は、ペーパーフィルタであるフィルタ31に加え、別フィルタ32を有するデュアル構造だがこれに限られない。フィルタ部530は、ペーパーフィルタであるフィルタ31に加え、2種類以上のフィルタを有してもよい。物体33により、フィルタ部530の咥え心地や手に持った感触等を向上させることができる。また、物体33は中空部材でもよい。 As described above, the filter section 530 of the flavor inhalation article 5 according to the fifth embodiment has the filter 31 which is a paper filter, the separate filter 32 which is an independent filter separate from the filter 31, and the object 33 which is placed within the filter 31 and is harder than the filter 31 at a position where the object 33 is not placed. In the above example, the filter section 530 has a dual structure having the separate filter 32 in addition to the filter 31 which is a paper filter, but this is not limited to this. The filter section 530 may have two or more types of filters in addition to the filter 31 which is a paper filter. The object 33 can improve the comfort of the filter section 530 in the mouth and the feel when held in the hand. The object 33 may also be a hollow member.
<第6実施形態>

Sixth Embodiment
Figure 18 is a diagram showing a longitudinal section of a flavor inhalation article 6 relating to the sixth embodiment, in which the object 33 is solid, (A) shows a state in which the object 33 is located on the first side of the aerosol modifier 34, (B) shows a state in which the object 33 is located on the second side of the aerosol modifier 34, and (C) shows a state in which the object 33 is located on both the first and second sides of the aerosol modifier 34.
The flavor inhalation article 6 according to the sixth embodiment is different from the flavor inhalation article 4 according to the fourth embodiment in that it has a filter part 630 corresponding to the filter part 30. The differences from the fourth embodiment will be described below. The same reference numerals are used for the same parts in the fourth and sixth embodiments, and detailed descriptions thereof will be omitted.
 フィルタ部630は、ペーパーフィルタであるフィルタ31と、フィルタ31のろ過率よりも低いろ過率の物体33と、エアロゾルを改質するエアロゾル改質剤34と、フィルタ31とチップペーパー40との間に存在してフィルタ31の外周面に巻かれる巻取紙35とを有している。フィルタ部630は、チップペーパー40を用いて、基材部10とフィルタ部630とが一体に巻き取られることで、基材部10と接続(連結)される。なお、巻取紙35は有さなくてもよい。
 フィルタ部630のエアロゾル改質剤34の構成は、第3実施形態に係るフィルタ部330に含まれるエアロゾル改質剤34と同一であることを例示することができる。
The filter unit 630 has a filter 31 which is a paper filter, an object 33 having a filtration rate lower than that of the filter 31, an aerosol modifier 34 which modifies the aerosol, and a winding paper 35 which is present between the filter 31 and the tipping paper 40 and which is wound around the outer circumferential surface of the filter 31. The filter unit 630 is connected (coupled) to the base material unit 10 by winding the base material unit 10 and the filter unit 630 together using the tipping paper 40. The winding paper 35 may not be provided.
The configuration of the aerosol modifier 34 in the filter section 630 can be, for example, the same as the aerosol modifier 34 included in the filter section 330 according to the third embodiment.
 物体33に対して第2側(下流側)であって、物体33と中心線方向の直線状に配置されたエアロゾル改質剤34を有している場合、図18(A)に示すように、連通孔460が、物体33とエアロゾル改質剤34との間の領域に設けられてもよい。また、連通孔460が、エアロゾル改質剤34に対して下流側の領域に設けられてもよい。
 その他、物体33に対して第1側(上流側)であって、物体33と中心線方向の直線状に配置されたエアロゾル改質剤34を有している場合、図18(B)に示すように、連通孔460が、物体33とエアロゾル改質剤34との間の領域に設けられてもよい。また、連通孔460が、エアロゾル改質剤34に対して上流側の領域に設けられてもよい。
 また、その他、物体33に対して第1側(上流側)及び第2側(下流側)であって、複数の物体33と中心線方向の直線状に配置されたエアロゾル改質剤34を有している場合、図18(C)に示すように、連通孔460が、物体33とエアロゾル改質剤34との間の領域に設けられてもよい。
18A , in the case of having an aerosol modifier 34 arranged on the second side (downstream side) of the object 33 and in a straight line with the object 33 in the center line direction, the communication hole 460 may be provided in the region between the object 33 and the aerosol modifier 34. The communication hole 460 may also be provided in the downstream region of the aerosol modifier 34.
18B , in the case where the aerosol modifier 34 is disposed on the first side (upstream side) of the object 33 and in a straight line with the object 33 in the center line direction, the communication hole 460 may be provided in the region between the object 33 and the aerosol modifier 34. The communication hole 460 may also be provided in the upstream region of the aerosol modifier 34.
In addition, in the case where there are aerosol modifiers 34 arranged on the first side (upstream side) and second side (downstream side) of the object 33 and in a straight line in the center line direction with respect to multiple objects 33, a communication hole 460 may be provided in the area between the objects 33 and the aerosol modifiers 34, as shown in Figure 18 (C).
 以上、説明したように、第6実施形態に係る香味吸引物品6のフィルタ部630は、ペーパーフィルタであるフィルタ31と、フィルタ31内に配置される物体33であって、物体33が配置されていない位置のフィルタ31より硬い物体33と、エアロゾルを改質するエアロゾル改質剤34とを有する。フィルタ部630内に物体33を有することで、フィルタ部630の咥え心地や使用感等を向上させることができる。また、物体33は中空部材でもよい。さらに、エアロゾル改質剤34は、エアロゾル改質剤34が配置されていない位置のフィルタ31よりも硬い場合は、第2の物体となり、フィルタ部630の咥え心地や使用感等を一層向上させることができる。 As described above, the filter section 630 of the flavor inhalation article 6 according to the sixth embodiment has the filter 31 which is a paper filter, an object 33 arranged within the filter 31 which is harder than the filter 31 in a position where the object 33 is not arranged, and an aerosol modifier 34 which modifies the aerosol. By having the object 33 within the filter section 630, the comfort of holding the filter section 630 in the mouth and the feeling of use can be improved. The object 33 may also be a hollow member. Furthermore, if the aerosol modifier 34 is harder than the filter 31 in a position where the aerosol modifier 34 is not arranged, it becomes a second object, and the comfort of holding the filter section 630 in the mouth and the feeling of use can be further improved.
