In addition, there is also a mode in which a tobacco sheet having one side of which is approximately the same size as the centerline direction of the object to be filled is wound in a direction orthogonal to the centerline direction of the object to be filled. mentioned.
 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。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。
As a mode in which the aerosol source 11 is composed of two or more tobacco sheets, for example, a plurality of tobacco sheets each having a size approximately equal to the size in the center line direction of the object to be filled, A mode in which the material is wound in a direction orthogonal to the center line direction of the material to be filled so as to be arranged concentrically is exemplified.
"Concentrically arranged" means that the centers of all the tobacco sheets are arranged at approximately the same position. In addition, the number of tobacco sheets is not particularly limited, but may be 2, 3, 4, 5, 6, or 7 sheets.

 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。
The aerosol source 11 prepares a plurality of tobacco sheets having different widths, prepares a laminated body in which the width decreases from the first side to the second side, passes the laminated body through a winding tube, and winds and forms the laminated body. It can be manufactured by
According to this manufacturing method, the plurality of tobacco sheets extend in the centerline direction and are arranged concentrically around CL.
 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。
In this manufacturing method, the laminate is preferably prepared so that a non-contact portion is formed between adjacent tobacco sheets after roll-forming. If there is a non-contact portion (gap) between the plurality of tobacco sheets, which is not in contact with the tobacco sheets, the flavor flow path can be secured and the delivery efficiency of the flavor component can be enhanced. On the other hand, since the heat from the heating part 121 can be transferred to the outer tobacco sheets through the contact portions of the plurality of tobacco sheets, high heat transfer efficiency can be ensured.
In order to provide a non-contact portion between a plurality of tobacco sheets where the tobacco sheets do not contact, for example, an embossed tobacco sheet is used, adjacent tobacco sheets are laminated without bonding the entire surfaces of adjacent tobacco sheets, and adjacent tobacco sheets are stacked together. Alternatively, the entire or part of the adjacent tobacco sheets are lightly adhered so that they can be separated after roll-forming, thereby preparing a laminate.

[Cooling part 20]
The cooling part 20 is arranged adjacent to the base material part 10 and the filter part 30, and is a member formed so that the cross section of a cylinder or the like is hollow (cavity) by winding the forming paper 21 thereon.
 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成形紙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 size of the cooling part 20 in the centerline direction can be appropriately changed according to the size of the product, but it is usually 5 mm or more, preferably 10 mm or more, and more preferably 15 mm or more. Also, the size of the cooling part 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 unit 20 in the center line direction to the above-described lower limit or more, it is possible to secure a sufficient cooling effect and obtain a good flavor. It is possible to suppress the loss caused by the aerosol adhering to the forming paper 21 .
 冷却部20は、内側の表面積が大きいことが望ましい。冷却部20を成形する成形紙21は、チャネルを形成するためにしわ付けされて、次に、ひだ付け、ギャザー付け、及び折り畳まれた薄い材料のシートによって形成されてもよい。要素の与えられた体積内の折り畳み又はひだが多いと、冷却部20の合計表面積が大きくなる。
 成形紙21の厚みは、特段制限されず、例えば、5μm以上500μm以下であって良く、また、10μm以上250μm以下であって良い。なお、成形紙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良く、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、またはこれらの任意の組み合わせであって良い。
The cooling part 20 preferably has a large inner surface area. The forming paper 21 forming the cooling section 20 may be formed by a thin sheet of material that is crumpled to form channels and then pleated, gathered and folded. The more folds or folds in a given volume of the element, the greater the total surface area of cooling section 20 .
The thickness of the molding paper 21 is not particularly limited, and may be, for example, 5 μm or more and 500 μm or less, or 10 μm or more and 250 μm or less.

 冷却部20には、その周方向に、かつ、同心状に複数の開孔V(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。開孔Vは、成形紙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。開孔Vは、スティック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にスティック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 part 20 is provided with a plurality of openings V (also called "ventilation filter (Vf)" in this technical field) concentrically and circumferentially. The aperture V is a hole penetrating the forming paper 21 . The shape of the hole can be exemplified by a polygon, a polygon with rounded corners, a circle, an ellipse, or the like. The opening V exists in a region where air can flow from the outside of the stick 1 , in other words, in a region where the stick 1 is held by the holding portion 140 of the suction device 100 and protrudes from the opening 142 .
 複数の開孔V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結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。冷却部20は、基材部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の一例である。
Due to the presence of the plurality of openings V, air flows into the cooling section 20 from the outside during suction, and the temperature of steam and air flowing from the base material section 10 can be lowered. Furthermore, by setting the position where the cooling unit 20 is provided within a region of 4 mm or more in the direction of the cooling unit 20 from the boundary between the cooling unit 20 and the filter unit 30, not only the cooling capacity is improved, but also the heat generated by heating It is possible to suppress the retention of the substance (product) in the cooling unit 20 and improve the delivery amount of the product.
It should be noted that the vapor generated by heating the base material portion 10 with the aerosol as the condensation nucleus is liquefied by contacting the air from the outside and the temperature is lowered, and the generation of the aerosol can be accelerated. . The cooling unit 20 is an example of a cooling unit that cools vapor generated by heating the base material to generate an aerosol.
 冷却部20にて、同心円状に存在する複数の開孔Vを1つの開孔群として扱った場合、開孔群は1つであってもよく、また、2つ以上であってもよい。開孔群が2つ以上存在する場合、加熱により生成される成分のデリバリー量向上の観点から、冷却部20とフィルタ部30との境界から、冷却部20側の方向の4mm未満の領域には開孔群を設けないことが好ましい。
 また、スティック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に設けられた開孔Vの直上の位置に開孔が設けられていることが好ましい。このようなスティック1を作製する場合、開孔Vと重なるような開孔を設けたチップペーパー40を準備して巻装してもよいが、製造容易性の観点から、開孔Vを有さないスティック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。
In the cooling unit 20, when a plurality of concentric holes V are treated as one hole group, the number of hole groups may be one, or two or more. When there are two or more hole groups, from the viewpoint of improving the delivery amount of the component generated by heating, from the boundary between the cooling unit 20 and the filter unit 30, in the region of less than 4 mm in the direction of the cooling unit 20 side It is preferable not to provide an aperture group.
Further, when the stick 1 has a configuration in which the base material portion 10, the cooling portion 20, and the filter portion 30 are wrapped with the tip paper 40, the tip paper 40 has the openings V provided in the cooling portion 20. It is preferable that an opening be provided at a position directly above. When such a stick 1 is produced, tipping paper 40 provided with openings overlapping with the openings V may be prepared and wound.

<<粉末供給路320の形態>>
 ここで、粉末供給路320の形態について、図3を用いて説明する。
 図3は、第1実施形態に係る第2フィルタ32の横断面の一例を示す図である。
 図3に示す本実施形態における粉末供給路320の横断面は、全体で一つの風車形状を有する開口として形成されている。より具体的には、第2フィルタ32の横断面において、粉末供給路320は、第2フィルタ32の中央側に位置する中央部321と、この中央部321から第2フィルタ32の外周側に向けて半径方向に延びる複数の周囲部322から形成されている。
<<Form of powder supply path 320>>
Here, the configuration of the powder supply path 320 will be described with reference to FIG. 3 .
FIG. 3 is a diagram showing an example of a cross section of the second filter 32 according to the first embodiment.
The cross section of the powder supply path 320 in this embodiment shown in FIG. 3 is formed as an opening having a single pinwheel shape as a whole. More specifically, in the cross section of the second filter 32, the powder supply path 320 includes a central portion 321 located on the central side of the second filter 32 and a portion extending from the central portion 321 toward the outer peripheral side of the second filter 32. It is formed from a plurality of radially extending perimeters 322 .
 粉末供給路320における複数の周囲部322は、それぞれ二等辺三角形状を有しており、中央部321から互いに異なる方向に放射状に延びている。また、各周囲部322における先端(中央部321とは反対側に位置する方の端部)は、第2フィルタ32の巻取紙35とは離間した位置に配置されており、各周囲部322の先端と巻取紙35との間に、第2フィルタ32を形成するフィルタ繊維が介在している。また、各周囲部322は、基端(中央部321に接続される方の端部)側から先端側に向かって徐々に開口幅が広がっている。よって、粉末供給路320における各周囲部322は、第2フィルタ32の横断面外周側に位置する外周側領域322aの方が、横断面中央側に位置する中央側領域322bに比べて開口幅が相対的に広くなっている。以上のように構成される第2フィルタ32の粉末供給路320は、原料粉末を塊とした球状の粉末含有物34の進入を抑制することで粉末含有物34がキャビティ33の下流に移動することを阻止する。具体的には、粉末供給路320は、塊状の粉末含有物34の直径よりも小さな開口幅を有している。 A plurality of peripheral portions 322 in the powder supply path 320 each have an isosceles triangular shape, and radially extend from the central portion 321 in mutually different directions. In addition, the tip of each peripheral portion 322 (the end located on the side opposite to the central portion 321) is arranged at a position separated from the paper roll 35 of the second filter 32, and the tip of each peripheral portion 322 and the web 35, the filter fibers forming the second filter 32 are interposed. In addition, the opening width of each peripheral portion 322 gradually widens from the proximal end (the end connected to the central portion 321) toward the distal end. Therefore, in each peripheral portion 322 in the powder supply path 320, the outer peripheral region 322a located on the outer peripheral side of the cross section of the second filter 32 has an opening width greater than the central region 322b located on the central side of the cross section. relatively wide. The powder supply passage 320 of the second filter 32 configured as described above suppresses the entry of the spherical powder inclusions 34 that are lumps of the raw material powder, thereby preventing the powder inclusions 34 from moving downstream of the cavity 33. prevent Specifically, the powder supply path 320 has an opening width that is smaller than the diameter of the lumped powder inclusion 34 .
 各周囲部322の開口面積は、中央部321の開口面積に比べて相対的に大きい。また、中央部321の開口幅は0.05mm以上0.9mm以下であることを例示することができる。また、周囲部322の基端の開口幅は0.05mm以上0.5mm以下であり、先端の開口幅は1mm以上3mm以下であることを例示することができる。 The opening area of each peripheral portion 322 is relatively large compared to the opening area of the central portion 321 . Also, the opening width of the central portion 321 can be exemplified to be 0.05 mm or more and 0.9 mm or less. Further, the width of the opening at the base end of the peripheral portion 322 is 0.05 mm or more and 0.5 mm or less, and the width of the opening at the tip is 1 mm or more and 3 mm or less.
 また、本実施形態における粉末供給路320は、複数の周囲部322の基端が中央部321によって互いに接続されており、一繋がりの開口となっている。そのため、第2フィルタ32の製造時において、単一のマンドレルを使用して第2フィルタ32を製造することができ、第2フィルタ32の横断面において粉末供給路320を除く領域に対して、フィルタ繊維を均一に充填することができる。つまり、第2フィルタ32の製造品質を安定することができる。なお、第2フィルタ32における粉末供給路320の形態については図3に示す風車タイプに限られず、種々の形態を採用できる。粉末供給路320は、曲線状、らせん状でもよい。さらに、粉末供給路320は、途中で分岐や合流があってもよい。また、粉末供給路320は、流路途中で径が変化するものでもよい。粉末供給路320の内径は、粉末含有物34の外径よりも小さければよい。また、粉末供給路320は、複数形成されていてもよい。また、第2フィルタ32は、貫通する粉末供給路320に加えて、非貫通の流路(図示せず)を更に備えるものでもよい。非貫通の流路を設けることで、貫通する粉末供給路320の流速を抑制することができる。その結果、粉末の供給量を抑制することができる。 In addition, in the powder supply path 320 in this embodiment, base ends of a plurality of peripheral portions 322 are connected to each other by a central portion 321 to form a continuous opening. Therefore, when manufacturing the second filter 32, the second filter 32 can be manufactured using a single mandrel. The fibers can be evenly packed. That is, the manufacturing quality of the second filter 32 can be stabilized. The form of the powder supply path 320 in the second filter 32 is not limited to the windmill type shown in FIG. 3, and various forms can be adopted. Powder feed path 320 may be curvilinear or spiral. Furthermore, the powder supply path 320 may branch or merge in the middle. Moreover, the diameter of the powder supply path 320 may change in the middle of the flow path. The inner diameter of the powder supply path 320 should be smaller than the outer diameter of the powder inclusion 34 . Also, a plurality of powder supply paths 320 may be formed. Moreover, the second filter 32 may further include a non-penetrating flow path (not shown) in addition to the penetrating powder supply path 320 . By providing the non-penetrating channel, the flow velocity of the penetrating powder supply channel 320 can be suppressed. As a result, the amount of powder supplied can be suppressed.
 以上、説明したように、スティック1は、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、フィルタ部30と、を備える。そして、フィルタ部30は、冷却部20側に配置された第1フィルタ31と、第1フィルタ31に対して冷却部20とは反対側に配置された第2フィルタ32と、第1フィルタ31と第2フィルタ32との間に形成されたキャビティ33に配置され、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原料粉末の塊であり、外力を加えることで粉末となる粉末含有物34と、を有し、第2フィルタ32には、キャビティ33と吸口端を連通すると共に粉末をキャビティ33から吸口端に供給するための粉末供給路320が形成されている。 As described above, the stick 1 includes the base portion 10 including the aerosol source 11, the cooling portion 20 that cools the vapor generated by heating the base portion 10 to generate the aerosol, and the filter. a portion 30; The filter unit 30 includes a first filter 31 arranged on the side of the cooling unit 20, a second filter 32 arranged on the side opposite to the cooling unit 20 with respect to the first filter 31, and the first filter 31. A powdery inclusion that is placed in a cavity 33 formed between the second filter 32 and is a lump of raw material powder containing at least one of a taste component and a flavoring component, and is turned into a powder by applying an external force. 34, and the second filter 32 is formed with a powder supply passage 320 for communicating the cavity 33 and the mouthpiece end and for supplying powder from the cavity 33 to the mouthpiece end.
 スティック1は、ユーザによりフィルタ部30に力が加えられて、粉末含有物34が粉末にされた状態で吸引装置100の保持部140内に挿入される。加熱部121により加熱された基材部10の温度が所定の温度に達した後、ユーザにより吸引されてエアロゾルが生成される。ユーザが吸引する際には、生成物であるエアロゾルと共に粉末が口腔内にデリバリーされる。これにより、新たな香喫味を付与することができる。 The stick 1 is inserted into the holding part 140 of the suction device 100 in a state in which the user applies force to the filter part 30 and the powder containing material 34 is pulverized. After the temperature of the substrate portion 10 heated by the heating portion 121 reaches a predetermined temperature, the user sucks the substrate portion 10 to generate an aerosol. When the user inhales, the powder is delivered into the oral cavity along with the product aerosol. Thereby, a new flavor and taste can be imparted.
 ここで、粉末含有物34が冷却部20に配置された場合には、粉末含有物34が潰されて得られる粉末を、基材部10の加熱により生じる蒸気が通過する。かかる場合には、粉末の水分含量が増加し、粉末のデリバリー効率が低下する。本実施の形態では、粉末含有物34がフィルタ部30に配置されるため、基材部10の加熱により生じる蒸気が冷却部20にて冷却されて生成されたエアロゾルが、粉末を通過する。これにより、粉末の水分含量の増加を抑制する。また、粉末の水分含量の増加による粉末のデリバリー効率の低下を抑制する。 Here, when the powder containing material 34 is arranged in the cooling unit 20, the vapor generated by heating the base material part 10 passes through the powder obtained by crushing the powder containing material 34. In such cases, the moisture content of the powder increases and the delivery efficiency of the powder decreases. In the present embodiment, since the powder inclusions 34 are arranged in the filter section 30, the vapor generated by heating the base material section 10 is cooled in the cooling section 20, and the aerosol generated passes through the powder. This suppresses an increase in the moisture content of the powder. In addition, it suppresses a decrease in powder delivery efficiency due to an increase in the moisture content of the powder.
 さらに、粉末含有物34が第1フィルタ31と第2フィルタ32との間のキャビティ33に収容されているため、基材部10と冷却部20とフィルタ部30とをチップペーパー40で接続する製造工程にて、粉末含有物34が脱落することを抑制する。また、搬送時などで粉末含有物34が脱落することを抑制する。 Furthermore, since the powder inclusions 34 are accommodated in the cavity 33 between the first filter 31 and the second filter 32, the base material part 10, the cooling part 20 and the filter part 30 are connected by the tip paper 40. In the process, the powder inclusions 34 are prevented from coming off. In addition, it prevents the powder containing material 34 from falling off during transportation.
 また、冷却部20における冷却は、蒸気を液化して、エアロゾルが生成される程度に冷却することを意味する。そのため、冷却部20にて生成されたエアロゾルをそのまま吸引すると、エアロゾルの温度が高く、ユーザが不快に感じるおそれがある。スティック1においては、フィルタ部30が、ユーザが吸引するに際しては高温であるエアロゾルを吸熱してさらに冷却する。また、第1フィルタ31は、基材部10や冷却部20への、粉末含有物34の移動または粉末の流入を抑制するために、中心線方向の貫通孔はない。他方、粉末が吸引され易いように第2フィルタ32には貫通孔である粉末供給路320を形成している。 Also, cooling in the cooling unit 20 means cooling to the extent that vapor is liquefied and aerosol is generated. Therefore, if the aerosol generated by the cooling unit 20 is sucked as it is, the temperature of the aerosol is high and the user may feel uncomfortable. In the stick 1, the filter part 30 absorbs heat from the aerosol, which is at a high temperature when the user inhales it, and further cools it. In addition, the first filter 31 does not have a through hole in the centerline direction in order to suppress the movement of the powder containing material 34 or the inflow of the powder to the base material part 10 and the cooling part 20 . On the other hand, the second filter 32 is formed with a powder supply passage 320, which is a through hole, so that the powder can be easily sucked.
 ここで、冷却部20は、外部から冷却部20内部に空気を流入する開孔を有すると良い。
 粉末を通過するエアロゾルは、水分子が表面に吸着した凝結核ではないことが望ましい。冷却部20に開孔Vがない場合、吸引時に外部から冷却部20の内部に空気が流入しないため、冷却部20内の温度が上昇し、基材部10から流入する蒸気の冷却が十分ではないおそれがある。本実施の形態では、外部の空気を流入する開孔Vがあるため、蒸気の冷却を促進することができる。これにより、吸引時における粉末のデリバリー効率を従来よりも改善することができる。
Here, the cooling part 20 preferably has an opening through which air flows into the cooling part 20 from the outside.
It is desirable that the aerosol that passes through the powder is not condensation nuclei with water molecules adsorbed to the surface. If there are no openings V in the cooling part 20, air does not flow into the cooling part 20 from the outside at the time of suction, so the temperature in the cooling part 20 rises, and the steam flowing in from the base material part 10 is not sufficiently cooled. There is a possibility that it will not. In the present embodiment, since there are openings V for inflow of outside air, it is possible to promote cooling of the steam. This makes it possible to improve the delivery efficiency of the powder during inhalation as compared with the conventional one.
 そして、粉末含有物34の大きさは、1mm以上8mm以下であると良い。
 粉末が口腔内にデリバリーされるために、粉末含有物34はユーザにより潰される必要がある。その際に、粉末含有物34の大きさが1mm未満の場合、フィルタ部30の変形が十分でないために粉末含有物34に与える外力が不十分となる。他方、粉末含有物34の大きさが8mmより大きい場合、粉末含有物34に与えるべき外力が大きくなるために粉末含有物34を潰すことができない可能性が高まる。また、粉末含有物34の破壊強度を小さくすると、ユーザの意図しない粉末含有物34の破壊が生じ得る。本実施の形態では、粉末含有物34の大きさは1mm以上8mm以下であるため、ユーザが容易に粉末含有物34を潰すことができる。
The size of the powder inclusion 34 is preferably 1 mm or more and 8 mm or less.
In order for the powder to be delivered into the oral cavity, the powder inclusion 34 must be crushed by the user. At this time, if the size of the powder inclusions 34 is less than 1 mm, the external force applied to the powder inclusions 34 is insufficient because the deformation of the filter portion 30 is insufficient. On the other hand, if the size of the powder inclusions 34 is larger than 8 mm, the external force to be applied to the powder inclusions 34 is increased, and the possibility that the powder inclusions 34 cannot be crushed increases. Further, if the breaking strength of the powder containing material 34 is reduced, the powder containing material 34 may be broken unintentionally by the user. In the present embodiment, the size of the powder inclusion 34 is 1 mm or more and 8 mm or less, so the user can easily crush the powder inclusion 34 .
 また、1つの粉末含有物34がキャビティ33に配置される場合、粉末含有物34の大きさは、3mm以上かつキャビティ33の内径よりも小さいと良い。
 キャビティ33に配置される粉末含有物34が1つである場合、粉末含有物34の大きさが3mm未満の場合、フィルタ部30の変形が十分でないために粉末含有物34に与える外力が不十分となる。本実施の形態では、粉末含有物34の大きさは3mm以上であるため、粉末含有物34に与える外力が不十分となる可能性を低減することができる。
Also, when one powder inclusion 34 is placed in the cavity 33 , the size of the powder inclusion 34 is preferably 3 mm or more and smaller than the inner diameter of the cavity 33 .
When only one powdery inclusion 34 is placed in the cavity 33 and the size of the powdery inclusion 34 is less than 3 mm, the external force applied to the powdery inclusion 34 is insufficient due to insufficient deformation of the filter section 30 . becomes. In the present embodiment, since the size of the powder inclusions 34 is 3 mm or more, it is possible to reduce the possibility that the external force applied to the powder inclusions 34 is insufficient.
 さらに、少なくとも2つの粉末含有物34がキャビティ33に配置される場合、粉末含有物34の大きさは、1mm以上かつキャビティ33の内径よりも小さいと良い。
 キャビティ33に配置される粉末含有物34が複数である場合、大きさが3mm未満の粉末含有物34であっても、キャビティは33に対する粉末含有物34の占有率を増加すれば十分な外力を与えることができる。しかしながら、大きさが1mm未満の粉末含有物34である場合、粉末供給路320の開口幅を粉末含有物34の大きさ未満に設計する必要がある。かかる場合には、高いデリバリー効率で口腔内への粉末を供給することは困難である。本実施の形態では、粉末含有物34の大きさは1mm以上であるため、粉末含有物34に与える外力が不十分となる可能性を低減することができる。
Furthermore, when at least two powder inclusions 34 are arranged in the cavity 33 , the size of the powder inclusions 34 should be 1 mm or more and smaller than the inner diameter of the cavity 33 .
When a plurality of powder inclusions 34 are arranged in the cavity 33, even if the size of the powder inclusions 34 is less than 3 mm, the cavity can apply a sufficient external force as long as the ratio of the powder inclusions 34 to the cavity 33 is increased. can give. However, when the size of the powder inclusions 34 is less than 1 mm, it is necessary to design the opening width of the powder supply path 320 to be smaller than the size of the powder inclusions 34 . In such cases, it is difficult to supply the powder into the oral cavity with high delivery efficiency. In the present embodiment, since the size of the powder inclusions 34 is 1 mm or more, the possibility that the external force applied to the powder inclusions 34 is insufficient can be reduced.
 またさらに、粉末含有物34が前記粉末となる破壊強度は、5N以上60N以下であると良い。
 粉末含有物34が粉末となる破壊強度が5N未満の場合、スティック1の製造工程、搬送、ユーザの意図しないタイミングにて、粉末含有物34が粉末となる可能性が高い。他方、粉末含有物34が粉末となる破壊強度が60Nより大きい場合、粉末となるように粉末含有物34全体を潰すことは困難である。本実施の形態では、破壊強度は5N以上60N以下であるため、ユーザが容易に粉末含有物34を粉末にすることができる。それゆえ、粉末供給路320を通ることができる大きさの粉末にすることができる。
Furthermore, the breaking strength at which the powder inclusion 34 becomes the powder is preferably 5N or more and 60N or less.
If the breaking strength at which the powdery inclusions 34 become powder is less than 5N, there is a high possibility that the powdery inclusions 34 become powder during the stick 1 manufacturing process, transportation, or timing not intended by the user. On the other hand, if the breaking strength at which the powder inclusion 34 becomes powder is greater than 60 N, it is difficult to crush the entire powder inclusion 34 into powder. In the present embodiment, since the breaking strength is 5N or more and 60N or less, the user can easily turn the powder inclusion 34 into powder. Therefore, the powder can be sized to pass through the powder supply path 320 .
 そして、粉末含有物34は、10μm以上600μm以下の粒子径を有する原料粉末が粉末含有物34の全質量の50質量%以上であると良い。
 粉末含有物34は破壊されて粉末の状態である際に、少なくとも一部が粉末供給路320を通過可能な粒子径を有している必要がある。粉末の粒子径は、粉末含有物34の原料粉末の粒子径に比例する傾向にある。粉末含有物34の原料粉末の粒子径が、例えば10μmより小さい場合、粒子径の小さい粉末が口腔内にデリバリーされても、香味成分や呈味成分をユーザが体感できないおそれがある。他方、粉末含有物34の原料粉末の粒子径が、例えば600μmより大きい場合、粒子径の大きい粉末は、質量が大きいためにデリバリー効率が低下するおそれがある。また、香味成分や呈味成分をユーザが体感するためには、粉末含有物34の全質量の50質量%以上の原料粉末が含有されていることが望ましい。本実施の形態では、吸引に適した粒径の粉末を得ることができる。
In the powder inclusions 34, it is preferable that the raw material powder having a particle diameter of 10 μm or more and 600 μm or less accounts for 50% by mass or more of the total mass of the powder inclusions 34.
The powder inclusion 34 needs to have a particle size that allows at least a portion of it to pass through the powder supply path 320 when it is broken into powder. The particle size of the powder tends to be proportional to the particle size of the raw material powder of the powder inclusion 34 . If the particle size of the raw material powder of the powder containing substance 34 is smaller than 10 μm, for example, even if the powder with a small particle size is delivered into the oral cavity, the user may not be able to sense the flavor and taste components. On the other hand, if the particle size of the raw material powder of the powder containing material 34 is larger than, for example, 600 μm, the powder with a large particle size has a large mass, which may reduce the delivery efficiency. Moreover, in order for the user to experience the flavor and taste components, it is desirable that the raw material powder is contained in an amount of 50% by mass or more of the total mass of the powder containing substance 34 . In this embodiment, powder having a particle size suitable for inhalation can be obtained.
 また、第2フィルタ32の横断面において、粉末供給路320は、第2フィルタ32の中央側に位置する中央部321と、中央部321から外周側に向けて互いに異なる方向に延びる複数の周囲部322を含む。
 キャビティ33に重力方向に堆積する粉末は、エアロゾルにより巻き上げられ、エアロゾルと共に粉末供給路320を通過することで、ユーザの口腔内にデリバリーされる。粉末供給路320が第2フィルタの横断面の中央側に1つの円柱状の粉末供給路である場合、限られた開口領域を巻き上げられた粉末が通過する必要がある。本実施の形態では、粉末供給路が、開口領域を一カ所に集中されずに、外周側に分散して配置されているので、吸引時における粉末のデリバリー量を増やすことができる。
In addition, in the cross section of the second filter 32, the powder supply path 320 includes a central portion 321 located on the central side of the second filter 32 and a plurality of peripheral portions extending in different directions from the central portion 321 toward the outer peripheral side. 322.
The powder deposited in the cavity 33 in the direction of gravity is picked up by the aerosol, passes through the powder supply path 320 together with the aerosol, and is delivered into the oral cavity of the user. If the powder supply path 320 is a single columnar powder supply path on the central side of the cross section of the second filter, it is necessary for the rolled up powder to pass through a limited opening area. In the present embodiment, the powder supply passages are arranged so that the opening regions are dispersed on the outer peripheral side without being concentrated in one place, so that it is possible to increase the delivery amount of the powder during suction.
 さらに、粉末供給路320は、粉末含有物34の大きさよりも小さい開口幅である。
 粉末供給路320は、第2フィルタ32の貫通孔として設けられる。粉末供給路320が粉末含有物34の大きさよりも大きい開口幅である場合、スティック1の製造工程や搬送工程にて、粉末含有物34がスティック1から脱落する可能性がある。本実施の形態では、粉末供給路320が粉末含有物34の大きさよりも小さい開口幅とするため、粉末含有物34がスティック1から脱落する可能性を低減することができる。
Further, the powder supply passage 320 has an opening width smaller than the size of the powder inclusions 34 .
The powder supply path 320 is provided as a through hole of the second filter 32 . If the powder supply path 320 has an opening width larger than the size of the powder containing material 34, the powder containing material 34 may drop off from the stick 1 during the stick 1 manufacturing process or transport process. In the present embodiment, the opening width of the powder supply path 320 is smaller than the size of the powder containing material 34, so the possibility that the powder containing material 34 falls off the stick 1 can be reduced.
