　香味吸引物品のフィルタとして、環境を考慮して例えばペーパーフィルタが用いられる場合がある。
　ここで、ペーパーフィルタのエアロゾルをろ過する能力は、酢酸セルロースなどの繊維を用いたフィルタよりも一般的に高い。そのため、ペーパーフィルタが用いられると、酢酸セルロースなどの繊維を用いたフィルタよりもエアロゾルによる香喫味が低減されてしまう。
　本発明の目的は、香味吸引物品にペーパーフィルタが用いられる場合において、香喫味のデリバリー効率を向上させることにある。 In some cases, for example, a paper filter is used as a filter for a flavor inhalation article in consideration of the environment.

An object of the present invention is to improve the delivery efficiency of a flavor when a paper filter is used in a flavor inhalation article.

The flavor inhalation article 1 according to the first embodiment includes a substrate 10, a cooling section 20, and a filter section 30. The mouthpiece segment 50 may be held by a user during inhalation, and includes the cooling section 20 and the filter section 30 in the example of FIG. 1. The substrate 10 is formed in a cylindrical shape. Hereinafter, the direction of the center line CL of the substrate 10 may be referred to as the "center line direction". The flavor inhalation article 1 further includes a tip paper 40 that integrates the substrate 10, the cooling section 20, and the filter section 30 by winding them in a state in which they are arranged in the center line direction. Hereinafter, one end side in the center line direction (left side in FIG. 1) may be referred to as the first side, and the other end side in the center line direction (right side in FIG. 1) may be referred to as the second side. The first side is the end side that is inserted into the inhalation device 100, and is the upstream side in the flow of aerosol during inhalation. The second side is the side opposite to the first side, which is the end side that the user holds in the mouth for inhalation and is the downstream side in the flow of the aerosol during inhalation. In addition, a cross section along the center line direction is called a "longitudinal cross section," and a cross section cut along a plane perpendicular to the center line direction is defined as a "transverse cross section."
［香味吸引物品１の使用形態］
　第１実施形態に係る香味吸引物品１は、非燃焼加熱式の吸引装置１００にて使用される。図２に示すように、吸引装置１００は、電力を蓄積するとともに、吸引装置１００の各構成要素に電力を供給する電源部１１１と、吸引装置１００に関する各種情報を検出するセンサ部１１２と、情報をユーザに通知する通知部１１３とを備えている。また、吸引装置１００は、吸引装置１００の動作のための各種情報を記憶する記憶部１１４と、吸引装置１００と他の装置との間で情報を送受信するための通信部１１５と、吸引装置１００内の動作全般を制御する制御部１１６とを備えている。また、吸引装置１００は、香味吸引物品１を加熱する加熱部１２１と、香味吸引物品１を保持する保持部１４０と、内部空間１４１を外部に連通する開口１４２と、加熱部１２１から吸引装置１００の他の構成要素への伝熱を防止する断熱部１４４とを備えている。吸引装置１００においては、保持部１４０に香味吸引物品１が保持された状態で、ユーザによる吸引が行われる。 [Usage form of flavor inhalation article 1]
The flavor suction article 1 according to the first embodiment is used in a non-combustion heating type suction device 100. As shown in FIG. 2, the suction device 100 includes a power supply unit 111 that accumulates power and supplies power to each component of the suction device 100, a sensor unit 112 that detects various information related to the suction device 100, and a notification unit 113 that notifies a user of the information. The suction device 100 also includes a storage unit 114 that stores various information for the operation of the suction device 100, a communication unit 115 for transmitting and receiving information between the suction device 100 and other devices, and a control unit 116 that controls the overall operation of the suction device 100. The suction device 100 also includes a heating unit 121 that heats the flavor suction article 1, a holding unit 140 that holds the flavor suction article 1, an opening 142 that communicates the internal space 141 with the outside, and a heat insulating unit 144 that prevents heat transfer from the heating unit 121 to other components of the suction device 100. In the inhalation device 100, the flavor inhalation article 1 is held in the holding portion 140, and the user inhales.
　加熱部１２１は、香味吸引物品１の基材部１０を加熱する。加熱部１２１は、金属又はポリイミド等の任意の素材で構成される。例えば、加熱部１２１は、フィルム状に構成され、保持部１４０の外周を覆うように配置される。そして、加熱部１２１が発熱すると、香味吸引物品１に含まれるエアロゾル源１１が香味吸引物品１の外周から加熱される。加熱部１２１は、電源部１１１から給電されると発熱する。一例として、所定のユーザ入力が行われたことがセンサ部１１２により検出された場合に、給電されてもよい。加熱部１２１により加熱された香味吸引物品１の温度が所定の温度に達した場合に、ユーザによる吸引が可能となる。その後、所定のユーザ入力が行われたことがセンサ部１１２により検出された場合に、給電が停止されてもよい。他の一例として、ユーザによる吸引が行われたことがセンサ部１１２により検出されている期間において、給電され、エアロゾルが生成されてもよい。 The heating unit 121 heats the base material 10 of the flavor inhalation article 1. The heating unit 121 is made of any material such as metal or polyimide. 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 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 surface 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 derived from tobacco, such as a processed product in which tobacco shreds or tobacco raw material is molded into a granular, sheet, or powder form. The aerosol source 11 may also include a non-tobacco-derived product made from plants other than tobacco (e.g., mint and herbs). As an example, the aerosol source 11 may include a flavoring. The type of flavoring is not particularly limited, and menthol is particularly preferred from the viewpoint of imparting a good flavor. These flavorings may be used alone or in combination of two or more types. When the inhalation device 100 is a medical inhaler, the aerosol source 11 may contain a drug for the patient to inhale. The aerosol source 11 is not limited to a solid, and may be, for example, a polyhydric alcohol such as glycerin and propylene glycol, or a liquid such as water. At least a part of the base material 10 is accommodated in the internal space 141 of the holding part 140 in a state in which the flavor inhalation article 1 is held by the holding part 140.

　また、中心線方向において、香味吸引物品１の大きさに対する基材部１０の大きさｈの割合は、特段制限されないが、デリバリー量とエアロゾル温度のバランスの観点から、通常１０％以上であり、２０％以上であることが好ましく、２５％以上であることがより好ましく、３０％以上であることがさらに好ましい。また、香味吸引物品１の大きさに対する基材部１０の大きさｈの割合は、通常８０％以下であり、７０％以下であることが好ましく、６０％以下であることがより好ましく、５０％以下であることがさらに好ましく、４５％以下であることが特に好ましく、４０％以下であることが最も好ましい。 The size h of the base material 10 in the center line direction can be changed appropriately according to the size of the product, but is usually 8 mm or more, and preferably 10 mm or more. The size h of the base material 10 in the center line direction is usually 70 mm or less, and preferably 30 mm or less.
In addition, in the center line direction, the ratio of the size h of the substrate 10 to the size of the flavor inhalation article 1 is not particularly limited, but from the viewpoint of the balance between the delivery amount and the aerosol temperature, it is usually 10% or more, preferably 20% or more, more preferably 25% or more, and even more preferably 30% or more. In addition, the ratio of the size h of the substrate 10 to the size of the flavor inhalation article 1 is usually 80% or less, preferably 70% or less, more preferably 60% or less, even more preferably 50% or less, particularly preferably 45% or less, and most preferably 40% or less.
　基材部１０中のエアロゾル源１１の含有量は、特段制限されないが、２００ｍｇ以上８００ｍｇ以下を挙げることができ、２５０ｍｇ以上６００ｍｇ以下が好ましい。この範囲は、特に、円周２２ｍｍ、中心線方向の大きさ２０ｍｍの基材部１０において好適である。 The amount of the aerosol source 11 contained in the base material 10 is not particularly limited, but may be 200 mg or more and 800 mg or less, and preferably 250 mg or more and 600 mg or less. This range is particularly suitable for a base material 10 having a circumference of 22 mm and a size in the center line direction of 20 mm.
　ここで、たばこ刻みを含むエアロゾル源１１を説明する。エアロゾル源１１に含まれるたばこ刻みの材料は特に限定されず、ラミナや中骨等の公知のものを用いることができる。また、乾燥したたばこ葉を平均粒径が２０μｍ以上２００μｍ以下になるように粉砕してたばこ粉砕物とし、これを均一化したものをシート加工したもの（以下、単に均一化シートともいう）を刻んだものであってもよい。さらに、基材部１０の中心線方向の大きさと同程度の大きさを有する均一化シートを、基材部１０の中心線方向と略水平に刻んだものをエアロゾル源１１に充填する、いわゆるストランドタイプであってもよい。
　また、たばこ刻みの幅は、エアロゾル源１１に充填するうえで０．５ｍｍ以上２．０ｍｍ以下であることが好ましい。 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 .
　たばこ刻み及び均一化シートの作製に用いるたばこ葉について、使用するたばこの種類は、様々なものを用いることができる。例えば、黄色種、バーレー種、オリエント種、在来種、その他のニコチアナ－タバカム系品種、ニコチアナ－ルスチカ系品種、及びこれらの混合物を挙げることができる。混合物については、目的とする味となるように、各品種を適宜ブレンドして用いることができる。たばこの品種の詳細は、「たばこの事典、たばこ総合研究センター、２００９．３．３１」に開示されている。均一化シートの製造方法、すなわち、たばこ葉を粉砕して均一化シートに加工する方法は従来の方法が複数存在している。１つ目は抄紙プロセスを用いて抄造シートを作製する方法である。２つ目は水等の適切な溶媒を、粉砕したたばこ葉に混ぜて均一化した後に金属製板もしくは金属製板ベルトの上に均一化物を薄くキャスティングし、乾燥させてキャストシートを作製する方法である。３つ目は水等の適切な溶媒を、粉砕したたばこ葉に混ぜて均一化したものをシート状に押し出し成型して圧延シートを作製する方法である。均一化シートの種類については、「たばこの事典、たばこ総合研究センター、２００９．３．３１」に詳細が開示されている。 Various types of tobacco can be used for the tobacco leaves used to make the shredded tobacco and homogenized sheets. 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。 The aerosol source 11 is not particularly limited and may contain various natural extracts and/or their components depending on the application. Examples of the extracts and/or their components include glycerin, propylene glycol, triacetin, 1,3-butanediol, and mixtures thereof.
The content of the extract and/or its constituent components in aerosol source 11 is not particularly limited, and from the viewpoint of generating a sufficient aerosol and imparting a good flavor, is usually 5% by mass or more, and preferably 10% by mass or more, based on the total amount of aerosol source 11. Moreover, the content of the extract and/or its constituent components in aerosol source 11 is usually 50% by mass or less, and preferably 15% by mass or more and 25% by mass or less.
　エアロゾル源１１における充填密度は、特に限定されないが、香味吸引物品１の性能を担保し、良好な香味を付与する観点から、通常２５０ｍｇ／ｃｍ３以上であり、好ましくは３００ｍｇ／ｃｍ３以上である。また、エアロゾル源１１における充填密度は、通常４００ｍｇ／ｃｍ３以下であり、好ましくは３５０ｍｇ／ｃｍ３以下である。 The filling density of the aerosol source 11 is not particularly limited, but is usually 250 mg/ cm3 or more, preferably 300 mg/ cm3 or more, from the viewpoint of ensuring the performance of the flavor inhalation article 1 and imparting a good flavor. The filling density of the aerosol source 11 is usually 400 mg/ cm3 or less, preferably 350 mg/ cm3 or less.
　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。
　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 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, bonding adjacent tobacco sheets together by bonding only a portion of the sheets together, or lightly bonding adjacent tobacco sheets together by 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.
　たばこシートは、抄造、スラリー、圧延、等の公知の方法で適宜製造できる。なお、上述した均一化シートを用いることもできる。
　抄造の場合は、以下の工程を含む方法で製造できる。１）乾燥たばこ葉を粗砕し、水で抽出して水抽出物と残渣に分離する。２）水抽出物を減圧乾燥して濃縮する。３）残渣にパルプを加え、リファイナで繊維化した後、抄紙する。４）抄紙したシートに水抽出物の濃縮液を添加して乾燥し、たばこシートとする。この場合、ニトロソアミン等の一部の成分を除去する工程を加えてもよい（特表２００４－５１０４２２号公報参照）。
　スラリー法の場合は、以下の工程を含む方法で製造できる。１）水、パルプ及びバインダーと、砕いたたばこ葉を混合する。２）混合物を薄く延ばして（キャストして）乾燥する。この場合、水、パルプ及びバインダーと、砕いたたばこ葉を混合したスラリーに対して紫外線照射もしくはＸ線照射することでニトロソアミン等の一部の成分を除去する工程を加えてもよい。 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. In this case, a step of removing some of the components such as nitrosamines by irradiating the slurry of the water, pulp, binder, and crushed tobacco leaves with ultraviolet light or X-rays 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。
　前記の各方法で用いる原料のたばこ葉の種類は、たばこ刻みを含むエアロゾル源１１で説明したものと同じものを用いることができる。
　たばこシートの組成は特に限定されないが、例えば、たばこ原料（たばこ葉）の含有量はたばこシート全質量に対して５０質量％以上９５質量％以下であることが好ましい。また、たばこシートはバインダーを含んでもよく、係るバインダーとしては、例えば、グアーガム、キサンタンガム、カルボキシメチルセルロース、カルボキシメチルセルロースのナトリウム塩等が挙げられる。バインダー量としては、たばこシート全質量に対して１質量％以上、１０質量％以下であることが好ましい。たばこシートはさらに他の添加物を含んでもよい。添加物としては、例えばパルプなどのフィラーを挙げることができる。 Alternatively, as described in WO 2014/104078, a nonwoven tobacco sheet may be used that is manufactured by a method that includes the following steps: 1) mixing powdered tobacco leaves with a binder; 2) sandwiching the mixture between nonwoven fabrics; and 3) forming the laminate into a certain shape by heat welding to obtain a nonwoven tobacco sheet.
The type of tobacco leaf material used in each of the above-mentioned methods can be the same as that described for the aerosol source 11 containing tobacco shreds.
The composition of the tobacco sheet is not particularly limited, but for example, the content of the tobacco raw material (tobacco leaves) is preferably 50% by mass or more and 95% by mass or less with respect to the total mass of the tobacco sheet. The tobacco sheet may also contain a binder, and examples of such binders include guar gum, xanthan gum, carboxymethylcellulose, and sodium salt of carboxymethylcellulose. The amount of the binder is preferably 1% by mass or more and 10% by mass or less with respect to the total mass of the tobacco sheet. The tobacco sheet may further contain other additives. Examples of additives include fillers such as pulp.
　基材部１０に使用する巻紙１２の構成は、特段制限されず、一般的な態様とすることができ、例えば、パルプが主成分のものを挙げることができる。パルプとしては、針葉樹パルプや広葉樹パルプなどの木材パルプで抄造される以外にも、亜麻パルプ、大麻パルプ、サイザル麻パルプ、エスパルトなど一般的にたばこ製品用の巻紙１２に使用される非木材パルプを混抄して製造して得たものでもよい。
　パルプの種類としては、クラフト蒸解法、酸性・中性・アルカリ亜硫酸塩蒸解法、ソーダ塩蒸解法等による化学パルプ、グランドパルプ、ケミグランドパルプ、サーモメカニカルパルプ等を使用できる。 The configuration of the cigarette paper 12 used in the base material 10 is not particularly limited and may be a common embodiment, for example one containing pulp as the main component. The pulp may be made from wood pulp such as softwood pulp or hardwood pulp, or may be made by mixing with non-wood pulp generally used in cigarette papers 12 for tobacco products, such as flax pulp, hemp pulp, sisal pulp, or esparto.
As the type of pulp, chemical pulp produced by the kraft cooking method, acidic/neutral/alkaline sulfite cooking method, soda salt cooking method, etc., ground pulp, chemi-ground pulp, thermomechanical pulp, etc. can be used.
　パルプを用いて長網抄紙機、円網抄紙機、円短複合抄紙機等による抄紙工程の中で、地合いを整え均一化して巻紙１２を製造する。なお、必要に応じて、湿潤紙力増強剤を添加して巻紙１２に耐水性を付与したり、サイズ剤を添加して巻紙１２の印刷具合の調整を行ったりすることができる。さらに、硫酸バンド、各種のアニオン性、カチオン性、ノニオン性或いは、両性の歩留まり向上剤、濾水性向上剤、及び紙力増強剤等の抄紙用内添助剤、並びに、染料、ｐＨ調整剤、消泡剤、ピッチコントロール剤、及びスライムコントロール剤等の製紙用添加剤を添加することができる。 The pulp is used in the papermaking process using a Fourdrinier papermaking machine, a cylinder papermaking machine, a combined cylinder and short-circuit papermaking machine, etc., to adjust and homogenize the texture of the wrapping paper 12. If necessary, a wet strength agent can be added to impart water resistance to the wrapping paper 12, or a sizing agent can be added to adjust the printing condition of the wrapping paper 12. In addition, papermaking internal additives such as aluminum sulfate, various anionic, cationic, nonionic, or amphoteric retention improvers, drainage improvers, and paper strength enhancers, as well as papermaking additives such as dyes, pH adjusters, defoamers, pitch control agents, and slime control agents can be added.

　さらに、坪量が２５ｇｓｍ以上３５ｇｓｍ以下のとき、填料の含有量が１５質量％以上４５質量％以下であることが好ましく、坪量が３５ｇｓｍ以上４５ｇｓｍ以下のとき、填料の含有量が２５質量％以上４５質量％以下であることが好ましい。
　填料としては、炭酸カルシウム、二酸化チタン、カオリン等を使用することができるが、香味や白色度を高める観点等から炭酸カルシウムを使用することが好ましい。 In addition to the above-mentioned pulp, a filler may be contained in the cigarette paper 12. The content of the filler relative to the total mass of the cigarette paper 12 can be 10% by mass or more and 60% by mass or less, and preferably 15% by mass or more and 45% by mass or less.
In the cigarette paper 12, within the preferred range of basis weight (25 gsm or more and 45 gsm or less), the filler content is preferably 15% by mass or more and 45% by mass or less.
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).

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 products, such as flax pulp, hemp pulp, sisal pulp, or esparto. These pulps may be used alone or in combination in any ratio.

Furthermore, these fillers may be used alone or in combination of two or more types.
　チップペーパー４０は、上述した材質や填料のほかに、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、耐水性向上剤を有することができる。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。 In addition to the materials and fillers described above, the tip paper 40 may contain various auxiliary agents, for example, a water resistance improver to improve water resistance. Water resistance improvers include wet strength agents (WS agents) and sizing agents. Examples of wet strength agents include urea formaldehyde resin, melamine formaldehyde resin, polyamide epichlorohydrin (PAE), etc. Examples of sizing agents include rosin soap, alkyl ketene dimer (AKD), alkenyl succinic anhydride (ASA), and highly saponified polyvinyl alcohol with a saponification degree of 90% or more.
　チップペーパー４０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、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。
　チップペーパー４０の外面の一部が、リップリリース材料によって被覆されていてもよい。リップリリース材料は、ユーザが香味吸引物品１のフィルタ部３０を口で咥えた際に、唇とチップペーパー４０との間の接触が実質的に粘着することなく容易に離れることを補助するように構成される材料を意味する。リップリリース材料は、例えば、エチルセルロース、メチルセルロース、ニトロセルロースなどを含んでいてもよい。例えば、チップペーパー４０の外面に対して、エチルセルロース系、或いは、メチルセルロース系のインクを塗工することでチップペーパー４０の外面をリップリリース材料によってコーティングしてもよい。 A coating agent may be added to at least one of the two surfaces, the front surface and the back surface, of the tipping paper 40. There are no particular limitations on the coating agent, but a coating agent that can form a film on the surface and reduce liquid permeability is preferred.
A part of the outer surface of the tipping paper 40 may be covered with a lip release material. The lip release material means a material configured to assist in easily releasing 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.
［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。
　冷却部２０の横断面は実質的に円形であり、その外径は、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の外径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、上記の外径は、その断面の面積と同じ面積を有する円で仮定し、その円における外径が適用される。
　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。 [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.
The cross section of the cooling section 20 is substantially circular, and its outer diameter can be appropriately changed according to the size of the product, but is preferably approximately the same as the outer diameter of the filter 31 described below. If the cross section is not circular, the above outer diameter is assumed to be a circle having the same area as the cross section, and the outer diameter of the 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、たばこ粉砕物など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。
　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。 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およ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。 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 steam 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、同心円状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 the plurality of through holes 60 concentrically arranged 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, it is preferable not to provide a through hole group in a region less than 4 mm from the boundary between the cooling section 20 and the filter section 30 in the direction toward the cooling section 20, from the viewpoint of improving the delivery amount of the component generated by heating.
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、加熱による生成物デリバリー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 product delivery 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 product delivery, a region of 4.5 mm or more is preferable, a region of 5 mm or more is more preferable, and a region of 5.5 mm or more is even more preferable. Also, from the viewpoint of ensuring 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 section 10 is considered as a reference, if the size of the cooling section 20 in the center line direction is 20 mm or more, from the viewpoint of ensuring the cooling function, 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 section 10 toward the cooling section 20, more preferably a region of 10 mm or more, and even more preferably a region of 13 mm or more. Furthermore, from the viewpoint of improving the delivery 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 section 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).

　フィルタ部３０は、中心線方向の大きさが横断面の幅よりも大きい柱状に形成されている。それゆえ、フィルタ部３０は、長手方向が中心線方向になるように配置されている。
　フィルタ部３０は、エアロゾルが通過するフィルタ３１と、フィルタ３１のろ過率よりも低いろ過率の低ろ過部材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３０は、チップペーパー４０を用いて、冷却部２０とフィルタ部３０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。 [Filter section 30]

The filter unit 30 is formed in a columnar shape whose size in the center line direction is greater than the width of the cross section, and is therefore disposed such that the longitudinal direction of the filter unit 30 coincides with the center line direction.

The filter unit 30 is connected (coupled) to the cooling unit 20 by winding up the cooling unit 20 and the filter unit 30 together using the tipping paper 40. The wrapping paper 35 may not be provided.

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 material of the wrapper 35 is not particularly limited, and any known material can be used, which may contain a filler such as calcium carbonate.
The thickness of the wrapper 35 is not particularly limited, and is usually from 20 μm to 140 μm, preferably from 30 μm to 130 μm, and more preferably from 30 μm to 120 μm.

　フィルタ部３０のフィルタ３１の横断面は実質的に円形であり、その外径は、製品のサイズに合わせて適宜変更し得るが、２２ｍｍ以上２５ｍｍ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、上記の外径は、その断面の面積と同じ面積を有する円で仮定し、その円における外径が適用される。
　フィルタ部３０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５．０ｍｍ以上３０．０ｍｍ以下であり、１２．５ｍｍ以上２７．５ｍｍ以下であることが好ましく、１５．０ｍｍ以上２５．０ｍｍ以下であることがより好ましい。 The cross section of the filter 31 of the filter unit 30 is substantially circular, and the outer diameter can be changed appropriately according to the size of the product, but can be 22 mm or more and 25 mm or less. If the cross section is not circular, the above outer diameter is assumed to be a circle having the same area as the cross section, and the outer diameter of the circle is applied.
The size of the filter portion 30 in the center line direction can be appropriately changed according to the size of the product, but is usually 5.0 mm or more and 30.0 mm or less, preferably 12.5 mm or more and 27.5 mm or less, and more preferably 15.0 mm or more and 25.0 mm or less.

　通気抵抗は、ＩＳＯ標準法（ＩＳＯ６５６５）に従って、例えばセルリアン社製フィルタ通気抵抗測定器を使用して測定される。フィルタ部３０の通気抵抗は、フィルタ部３０の側面における空気の透過が行なわれない状態で第１側から第２側に所定の空気流量（１７．５ｃｃ／ｍｉｎ）の空気を流した際の、第１側と第２側との気圧差を指す。単位は、一般的にはｍｍＨ２Ｏで表す。 The airflow resistance per 10 mm of size in the center line direction of the filter portion 30 is not particularly limited, but is usually 0 mmH2O to 100 mmH2O, preferably 10 mmH2O to 80 mmH2O, and more preferably 10 mmH2O to 50 mmH2O.
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、シート部材を充填して成形したものであって、エアロゾルが通過することが可能なチャネルが形成されたペーパーフィルタである。換言すると、フィルタ３１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の充填密度は、特段制限されないが、通常９０ｍｇ／ｃｍ３以上７２０ｇ／ｃｍ３以下である。図３（Ａ）に示すように、低ろ過部材３３が配置されていない領域のシート部材の充填密度は、９０ｍｇ／ｃｍ３以上３６０ｇ／ｃｍ３以下であることが好ましく、１５０ｍｇ／ｃｍ３以上２４０ｇ／ｃｍ３以下であることがより好ましい。また、図３（Ｂ）に示すように、低ろ過部材３３が配置されている領域のシート部材の充填密度は、１０５ｍｇ／ｃｍ３以上７２０ｇ／ｃｍ３以下であることが好ましく、１７０ｍｇ／ｃｍ３以上４８０ｇ／ｃｍ３以下であることがより好ましい。 The filter 31 is a paper filter that is filled with a sheet member and has channels through which an aerosol can pass. In other words, the filter 31 is a paper filter that is filled with a sheet member so as to ensure a passage path for the aerosol extending in the center line direction.
The packing density of the sheet member constituting the filter 31 is not particularly limited, but is usually 90 mg/cm 3 or more and 720 g/cm 3 or less. As shown in Fig. 3(A), the packing density of the sheet member in the region where the low filtration member 33 is not arranged is preferably 90 mg/cm 3 or more and 360 g/cm 3 or less, and more preferably 150 mg/cm 3 or more and 240 g/cm 3 or less. Also, as shown in Fig. 3(B), the packing density of the sheet member in the region where the low filtration member 33 is arranged is preferably 105 mg/cm 3 or more and 720 g/cm 3 or less, and more preferably 170 mg/cm 3 or more and 480 g/cm 3 or less.
　フィルタ３１を構成するシート部材の材質は、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また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の材質に、例えばポリマーシート、金属シートなど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。 The material of the sheet member 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 whose main component is pulp, and more preferably paper. Other materials such as polymer sheets and metal sheets may be used for the sheet member constituting the filter 31. The general functions of a filter include, for example, adjusting the amount of air mixed in when inhaling an aerosol, reducing flavor, 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 1, which tends to generate fewer components and has a lower filling rate of the aerosol source 11 compared to cigarette products, one important function is to suppress the filtering function while preventing the components contained in the flavor inhalation article 1 from falling off.
　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が形成されるようにシート部材が充填されたペーパーフィルタであって、シート部材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が充填されたペーパーフィルタでもよい。 The filter 31 is formed of a sheet member 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 is filled so as to form voids along the longitudinal direction of the filter section 30, and the sheet member is gathered.
Here, "gathered" means that the sheet member 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 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 as shown in FIG. 4(A).
　低ろ過部材３３は、フィルタ３１内に配置され、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。
　低ろ過部材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つの低ろ過部材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、複数の低ろ過部材３３がフィルタ３１内に配置されてもよい。 The low filtration member 33 is disposed within the filter 31 and is a member having a lower filtering function than the filter 31 for the aerosols passing therethrough.
There may be one low filtration member 33 or two or more low filtration members 33. Specifically, as shown in Fig. 3(B) , one low filtration member 33 may be disposed in the filter 31, or as shown in Fig. 4(B) , a plurality of low filtration members 33 may be disposed in the filter 31.
　低ろ過部材３３の横断面において、その外周の形状は、製品の形状に合わせて適宜変更し得るが、例えば円、楕円、多角、角丸多角である。
　また、横断面において、フィルタ部３０の面積に対する低ろ過部材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、複数の低ろ過部材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低ろ過部材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。 In the cross section of the low filtration member 33, the outer circumferential shape can be appropriately changed according to the shape of the product, and is, for example, a circle, an ellipse, a polygon, or a polygon with rounded corners.
In addition, in a cross section, the ratio of the area of the low filtration member 33 to the area of the filter section 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 multiple low filtration members 33 are arranged in the filter 31, it is preferable that the ratio of the total area of the multiple low filtration members 33 to the area of the filter section 30 in one cross section is within the above range.
　低ろ過部材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、その外径は、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の外径に対する低ろ過部材３３の外径の比率は、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、上記の外径は、その断面の面積と同じ面積を有する円で仮定し、その円における外径が適用される。 When the cross section of the low filtration member 33 has a substantially circular outer periphery, its outer diameter can be changed as appropriate to suit 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 outer diameter of the low filtration member 33 to the outer diameter 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. If the cross section is not circular, the above outer diameter is assumed to be a circle having the same area as the cross section, and the outer diameter of that circle is applied.
　低ろ過部材３３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、
フィルタ３１の中心線方向の大きさよりも大きくないことが好ましい。換言すると、低ろ過部材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。
　また、低ろ過部材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、低ろ過部材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、低ろ過部材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、低ろ過部材３３がフィルタ３１の少なくとも一方の端面から突出せず、低ろ過部材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、低ろ過部材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低ろ過部材３３が見えないようにすることができる。 The size of the low filtration member 33 in the center line direction can be changed appropriately according to the size of the product.
It is preferable that the length of the low filtration member 33 in the longitudinal direction of the filter portion 30 is not longer than the length of the filter 31 in the longitudinal direction of the filter portion 30.
Furthermore, when the size of the low filtration member 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 low filtration member 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 low filtration member 33 smaller than the size of the filter 31 in the center line direction, the low filtration member 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 low filtration member 33. By making the low filtration member 33 2 mm or more smaller than the filter 31 in the center line direction, the low filtration member 33 can be made invisible from at least one end of the filter 31.
　低ろ過部材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。低ろ過部材３３を中心線方向の少なくとも一端が開口した中空部材とすることで、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。また、低ろ過部材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。
　低ろ過部材３３が中心線方向の両端が開口した中空部材である場合、低ろ過部材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。 The low filtration member 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. By making the low filtration member 33 a hollow member having at least one end in the center line direction open, it is possible to suppress the filtering function for the aerosol passing through and improve the delivery efficiency of the flavor. In addition, by making the low filtration member 33 a hollow member having both ends in the center line direction open, it is possible to suppress the filtering function for the aerosol passing through and improve the delivery efficiency of the flavor compared to a member having one end in the center line direction closed.
When the low filtration member 33 is a hollow member with both ends in the center line direction open, it does not filter at all the aerosol passing through the low filtration member 33. In addition, a filtration rate lower than the filtration rate of the filter 31 also includes a filtration rate of "0%".
　ここで、低ろ過部材３３の構成の具体例を説明する。
　例えば、低ろ過部材３３は、フィルタ３１を構成するシート部材と同様の材質を含むシート部材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、低ろ過部材３３は、紙が巻かれることで成形された紙管である。低ろ過部材３３を紙管とすることで、低ろ過部材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 low filtration member 33 will be described.
For example, the low filtration member 33 is a tube formed by winding a sheet member containing the same material as the sheet member constituting the filter 31 so that the cross section of a cylinder or the like is hollow. Specifically, the low filtration member 33 is a paper tube formed by winding paper. By using a paper tube for the low filtration member 33, the material constituting the low filtration member 33 can be substantially the same as that of the filter 31.
　低ろ過部材３３は、少なくとも紙を含む複数のシート部材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。低ろ過部材３３にスパイラル紙管を採用することで、フィルタ部３０の面積に対する低ろ過部材３３の面積の割合を抑えつつ、低ろ過部材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、たばこ粉砕物など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。 The low filtration member 33 is a paper tube formed by bonding together a number of sheet members, including at least paper, and winding them in a spiral shape, a so-called spiral paper tube. The method of manufacturing a spiral paper tube makes it possible to easily form a paper tube with a circular cross section. By using a spiral paper tube for the low filtration member 33, the strength of the low filtration member 33 can be improved while suppressing the ratio of the area of the low filtration member 33 to the area of the filter section 30. In addition, by combining and bonding sheet members containing fragrance components, flavor components, tobacco powder, etc. with paper, a new aroma and flavor can be imparted to the aerosol.
　その他、低ろ過部材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、低ろ過部材３３は、少なくとも紙を含む複数のシート部材が積層されて成形された紙管であってもよい。複数のシート部材が積層されることで、シート部材の各々の坪量が小さい場合にも低ろ過部材３３の強度を維持させることができる。
　なお、低ろ過部材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。低ろ過部材３３が管である場合、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、シート部材が重なる場合、重なったシート部材の厚さの合計が、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などの外部からの圧力による低ろ過部材３３の変形を抑制することができる。 Alternatively, the low filtration member 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.
The low filtration member 33 may be a paper tube formed by stacking a plurality of sheet members including at least paper. By stacking a plurality of sheet members, the strength of the low filtration member 33 can be maintained even when the basis weight of each of the sheet members is small.
The low filtration member 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 low filtration member 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 sheet members are overlapped, the total thickness of the overlapped sheet members may be within the above range. By setting the wall thickness of the tube within the above range, deformation of the low filtration member 33 due to external pressure such as the filter 31 can be suppressed.
　低ろ過部材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。低ろ過部材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。 The low filtration member 33 is a hollow member with a hollow cross section, but is not limited to this configuration as long as it has a lower filtration rate than the filter 31. The low filtration member 33 may be formed from a solid member with a solid cross section, such as cellulose acetate fiber, which has a lower filtration rate than paper.
　低ろ過部材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。
　図５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）は第２側が先鋭である低ろ過部材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低ろ過部材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、低ろ過部材３３の中心線方向の端部の形状は、図５（Ａ）に示すように、低ろ過部材３３の第１側の端面が平面であり、低ろ過部材３３の第２側の端面が先鋭であってもよい。また、例えば、図５（Ｂ）に示すように、第２側領域の方が、第１側領域に比べて低ろ過部材３３の幅が相対的に小さくなってもよい。 The shape of the end portion of the low filtration member 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.
Figure 5 is a diagram showing another example of a longitudinal section of the flavor inhalation article 1 according to the first embodiment, in which (A) is a diagram showing a longitudinal section of a low filtration member 33 having a sharp second side, and (B) is a diagram showing a longitudinal section of a flavor inhalation article 1 having a low filtration member 33 whose width decreases from the first side to the second side.
For example, as shown in Fig. 5(A), the shape of the end portion in the center line direction of the low filtration member 33 may be such that the end face on the first side of the low filtration member 33 is flat and the end face on the second side of the low filtration member 33 is sharp. Also, as shown in Fig. 5(B), for example, the width of the low filtration member 33 may be relatively smaller in the second side region than in the first side region.
　ここで、図１，図６，図７を用いて、低ろ過部材３３の配置の具体例を説明する。
　図６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）は低ろ過部材３３がフィルタ３１内の第２側に位置する状態、（Ｂ）は低ろ過部材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７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と同一の低ろ過部材３３がフィルタ３１内に位置する状態、（Ｂ）は複数の低ろ過部材３３がフィルタ３１内に位置する状態を示す図である。
　低ろ過部材３３は、低ろ過部材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 low filtration member 33 will be described with reference to FIGS.
Figure 6 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 low filtration member 33 is positioned on the second side within the filter 31, and (B) shows a state in which the low filtration member 33 is positioned toward the center within the filter 31.
Figure 7 shows 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 a low filtration member 33 having the same size in the center line direction as the filter 31 is positioned within the filter 31, and (B) shows a state in which multiple low filtration members 33 are positioned within the filter 31.
The low filtration member 33 is preferably arranged so that the low filtration member 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低ろ過部材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、低ろ過部材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）に低ろ過部材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側の端面から低ろ過部材３３が見えないようにすることができる。 In the example shown in FIG. 1, the low filtration member 33, which is smaller than the size of the filter 31 in the center line direction, is located on the first side (substrate part 10 side) within the filter 31. Specifically, the low filtration member 33 is disposed in the upstream region within the filter 31. By disposing the low filtration member 33 on the first side (substrate part 10 side) within the filter 31, it is possible to realize suitable filtration of the aerosol while preventing the low filtration member 33 from being seen from the end face on the second side of the filter 31.
　図６（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い低ろ過部材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、低ろ過部材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）の領域に低ろ過部材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ることができる。
　低ろ過部材３３の第２側の端面が、図６（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、低ろ過部材３３がフィルタ３１内の第２側に位置する場合、低ろ過部材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。低ろ過部材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側の端面から低ろ過部材３３が見えないようにすることができる。 6(A), the low filtration member 33, which is 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 low filtration member 33 is disposed in the second side region within the filter 31. By disposing the low filtration member 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.
6A, the end face on the second side of the low filtration member 33 is located on 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 low filtration member 33 is located on the second side within the filter 31, the end face on the second side of the low filtration member 33 may be spaced 2 mm or more from the end face on the second side of the filter 31. By spaced 2 mm or more from the end face on the second side of the filter 31, the low filtration member 33 can be made 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低ろ過部材３３の配置は、フィルタ３１内の第１側の領域または第２側の領域に限られない。
　図６（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低ろ過部材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、低ろ過部材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低ろ過部材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 low filtration member 33 , which 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 .
6(B), the low filtration member 33, which is 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 low filtration member 33 is disposed in a region toward the center of the filter 31 in the center line direction. By disposing the low filtration member 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.
　低ろ過部材３３は、低ろ過部材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７（Ａ）に示すように、中心線方向の大きさがフィルタ３１と同一の低ろ過部材３３がフィルタ３１内に配置されてもよい。
　また、複数の低ろ過部材３３を配置する場合、低ろ過部材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７（Ｂ）に示すように、フィルタ３１内の複数の領域に低ろ過部材３３が配置されてもよい。
　フィルタ３１に対する低ろ過部材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 low filtration member 33 is not limited to the above-mentioned configuration as long as it is arranged so that the low filtration member 33 does not protrude from the end face on the second side of the filter 31 .
As shown in FIG. 7A, a low filtration member 33 having the same size as the filter 31 in the center line direction may be disposed within the filter 31.
Furthermore, when a plurality of low filtration members 33 are arranged, the arrangement of the low filtration members 33 is not limited to the same region in the center line direction as shown in Fig. 4(B). As shown in Fig. 7(B), the low filtration members 33 may be arranged in a plurality of regions within the filter 31.
By increasing the ratio of the low filtration member 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.
　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に配置される部材であってフィルタ３１のろ過率よりも低いろ過率の低ろ過部材３３とを有する。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 that cools the steam generated by heating the substrate 10 to generate an aerosol, a filter section 30 through which the aerosol passes, and tipping paper 40 that is wound around the outer peripheral surfaces of the substrate 10, the cooling section 20, and the filter section 30. The filter section 30 includes a filter 31 that is a paper filter filled with a sheet member, and a low filtration member 33 that is a member disposed in the filter 31 and has a filtration rate lower than that of the filter 31. Note that the flavor inhalation article 1 does not need to include a cooling section 20 from the viewpoint of compact size in the center line direction.
＜第２実施形態＞
　図８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）は低ろ過部材３３がフィルタ３１内の第１側に位置する状態、（Ｂ）は低ろ過部材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 8 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 low filtration member 33 is positioned on a first side within the filter 31, and (B) shows a state in which the low filtration member 33 is positioned 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のろ過率よりも低いろ過率の低ろ過部材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, a low filtration member 33 which has a lower filtration rate than that of the filter 31, and a winding paper 35 which is between the filter 31 and the tipping paper 40 and which is wound around the outer periphery of the filter 31. The filter section 230 is connected (coupled) 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 winding paper 35, and then wound together with yet another winding 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、その外径は、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、上記の外径は、その断面の面積と同じ面積を有する円で仮定し、その円における外径が適用される。
　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 outer diameter 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 outer diameter is assumed to be a circle having the same area as the cross section, and the outer diameter of the 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スティック１においては、濾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 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 stick 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 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、パーミキュライト、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／ｃｍ３以上３６０ｍｇ／ｃｍ３以下であり、１５０ｍｇ／ｃｍ３以上２４０ｍｇ／ｃｍ３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, permiculite, 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８（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い低ろ過部材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、低ろ過部材３３が配置されている。 In the example shown in FIG. 8(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 low filtration member 33 that is smaller than the size of the filter 31 in the center line direction is disposed on the first side (substrate section 10 side) within the filter 31. Specifically, the low filtration member 33 is disposed in the upstream region within the filter 31.
　図８（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低ろ過部材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、低ろ過部材３３が配置されてもよい。低ろ過部材３３がフィルタ３１内の第２側に位置する場合、低ろ過部材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. 8(B), a low filtration member 33 that is 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 low filtration member 33 may be disposed in the second side region of the filter 31. When the low filtration member 33 is positioned on the second side of the filter 31, it is preferable that the end face of the second side of the low filtration member 33 is separated from the end face of the second side of the filter 31 by 2 mm or more.
　フィルタ部２３０の構成は、図８（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９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）は低ろ過部材３３がフィルタ３１内の第１側に位置する状態、（Ｂ）は低ろ過部材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。 The configuration of the filter unit 230 is not limited to the examples shown in FIGS. 8A and 8B, and the positional relationship between the filter 31 and the separate filter 32 may be changed.
Figure 9 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 low filtration member 33 is positioned on a first side within the filter 31, and (B) shows a state in which the low filtration member 33 is positioned 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い低ろ過部材３３が、図９（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９（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、低ろ過部材３３が配置されてもよい。 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.
The low filtration member 33, which is 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. 9(A), or may be disposed on a second side (downstream side) in the filter 31 as shown in Fig. 9(B). Specifically, the low filtration member 33 may be disposed in a region on the second side in the filter 31.
　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、フィルタ３１のろ過率よりも低いろ過率の低ろ過部材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に低ろ過部材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。
　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 low filtration member 33 which has a filtration rate lower than that of the filter 31. 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 low filtration member 33 in the filter 31 which has a lower hardness than the separate filter 32 can increase the strength of the area held in the user's mouth.
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１０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）は低ろ過部材３３がエアロゾル改質剤３４の第１側に位置する状態、（Ｂ）は低ろ過部材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 10 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 low filtration member 33 is positioned on the first side of the aerosol modifier 34, and (B) shows a state in which the low filtration member 33 is positioned 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 it has a filter portion 330 corresponding 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の低ろ過部材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 low filtration member 33 with 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 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 may not be included.
　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、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、低ろ過部材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、低ろ過部材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、低ろ過部材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低ろ過部材３３を通過するような位置などの低ろ過部材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が低ろ過部材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 The aerosol modifier 34 is disposed inside the filter portion 330 .
The position of the aerosol modifier 34 in the vertical cross section of the filter section 330 is not particularly limited, but it is preferable that the aerosol modifier 34 is arranged in a straight line in the center line direction with the low filtration member 33. In other words, it is preferable that the aerosol modifier 34 is arranged in a straight line in the longitudinal direction of the low filtration member 33 and the filter section 330.
Specifically, the aerosol modifier 34 is preferably disposed at a position corresponding to the low filtration member 33, such as a position through which the aerosol that has passed through the low filtration member 33 passes, or a position through which the aerosol that has collided with the aerosol modifier 34 passes through the low filtration member 33. By disposing the aerosol modifier 34 at a position corresponding to the low filtration member 33, the delivery efficiency of the modified aerosol can be improved.
　図１０（Ａ）に示す例では、フィルタ部３３０は、低ろ過部材３３に対して第２側（下流側）であって、低ろ過部材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、低ろ過部材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、低ろ過部材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. 10(A), the filter section 330 has an aerosol modifier 34 that is on the second side (downstream side) of the low filtration member 33 and is arranged in a straight line with the low filtration member 33 in the center line direction. By arranging the aerosol modifier 34 on the second side (suction mouth end side) of the low filtration member 33 and in a straight line in the longitudinal direction of the filter section 330, the aerosol that has passed through the low filtration member 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１０（Ｂ）に示すように、フィルタ部３３０は、低ろ過部材３３に対して第１側（上流側）であって、低ろ過部材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、低ろ過部材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低ろ過部材３３に通過させることができる。また、フィルタ部３３０にて第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. 10(B), the filter section 330 may have an aerosol modifier 34 arranged on the first side (upstream side) of the low filtration member 33 and in a straight line with the low filtration member 33 in the center line direction. By arranging the aerosol modifier 34 on the first side (substrate section 10 side) of the low filtration member 33 and in a straight line in the longitudinal direction of the filter section 330, the modified aerosol can be passed through the low filtration member 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。
　内容物が液体また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/ｍｍ２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２３１の横断面の面積当たりの内容物の液体量が２．２μｌ/ｍｍ２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/ｍｍ２以上２．２μｌ/ｍｍ２以下であり、０．３μｌ/ｍｍ２以上０．７μｌ/ｍｍ２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, if 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, if the amount of liquid of the contents per cross-sectional area of the filter 231 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、パーミキュライト、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, permiculite, 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、フィルタ３１のろ過率よりも低いろ過率の低ろ過部材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 low filtration member 33 which has a lower filtration rate than that of the filter 31, and the aerosol modifier 34 which modifies the aerosol. By having the aerosol modifier 34 in the filter section 330, it is possible to modify the aerosol generated from the base section 10 during inhalation. In addition, since the aerosol modifier 34 is a breakable capsule which releases a content liquid containing a flavor component when an external force is applied, it is possible to impart a new flavor and taste to the aerosol.
＜第４実施形態＞
　図１１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. 11 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、その外径は、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、上記の外径は、その断面の面積と同じ面積を有する円で仮定し、その円における外径が適用される。
　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 member 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 its outer diameter can 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 above outer diameter is assumed to be a circle having the same area as the cross section, and the outer diameter 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のうちの低ろ過部材３３が配置されていない領域であることが好ましい。
　図１１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低ろ過部材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のうちの低ろ過部材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が低ろ過部材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 the low filtration material 33 is not arranged.
11 , the low filtration member 33, which is smaller than the size of the filter 31 in the center line direction, is located on the first side (substrate portion 10 side) within the filter 31, and the communication hole 460 is provided in a region of the filter 31 where the low filtration member 33 is not disposed.
　連通孔４６０は、フィルタ３１のうちの低ろ過部材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１２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、（Ａ）は低ろ過部材３３がフィルタ３１内の第２側に位置する状態、（Ｂ）は低ろ過部材３３がフィルタ３１内の中央寄りに位置する状態、（Ｃ）は複数の低ろ過部材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 a region of the filter 31 where the low filtration member 33 is not disposed.
Figure 12 is a diagram showing another example of a longitudinal section of the flavor inhalation article 4 according to the fourth embodiment, in which (A) shows a state in which the low filtration member 33 is positioned on the second side within the filter 31, (B) shows a state in which the low filtration member 33 is positioned toward the center within the filter 31, and (C) shows a state in which multiple low filtration members 33 are positioned 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低ろ過部材３３がフィルタ３１内の第２側（下流側）に位置する場合、図１２（Ａ）に示すように、連通孔４６０が低ろ過部材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低ろ過部材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１２（Ｂ）に示すように、連通孔４６０が低ろ過部材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、低ろ過部材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内の複数の領域に低ろ過部材３３が配置されている場合、図１２（Ｃ）に示すように、連通孔４６０がフィルタ３１のうちの低ろ過部材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、低ろ過部材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 a low filtration member 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 low filtration member 33, as shown in Figure 12 (A).
12B , in the case where the low filtration member 33, which is 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 low filtration member 33. Note that the communication hole 460 may be provided in a region downstream of the low filtration member 33.
12C , in the case where the low filtration members 33 are arranged in a plurality of regions in the filter 31, the communication hole 460 may be provided in a region of the filter 31 where the low filtration members 33 are not arranged. The communication hole 460 may be provided in any region on the upstream side, the central side, or the downstream side, so long as the region does not have the low filtration member 33.
　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に配置される部材であってフィルタ３１のろ過率よりも低いろ過率の低ろ過部材３３とを有する。燃焼型の香味吸引物品にペーパーフィルタが用いられる場合において、香喫味のデリバリー効率を向上させることができる。 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 wound around the outer peripheral surfaces of the base member 10 and the filter member 30. The filter member 30 includes a filter 31 which is a paper filter filled with a sheet member, and a low filtration member 33 which is a member disposed in the filter 31 and has a filtration rate lower than that of the filter 31. When a paper filter is used in a combustion-type flavor inhalation article, the delivery efficiency of the smoking flavor can be improved.
＜第５実施形態＞
　図１３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、（Ａ）は低ろ過部材３３がフィルタ３１内の第１側に位置する状態、（Ｂ）は低ろ過部材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 13 is a diagram showing a longitudinal section of the flavor inhalation article 5 according to the fifth embodiment, in which (A) shows a state in which the low filtration member 33 is positioned on a first side within the filter 31, and (B) shows a state in which the low filtration member 33 is positioned 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のろ過率よりも低いろ過率の低ろ過部材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２３０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 an independent filter separate from the filter 31, a low filtration member 33 having a filtration rate lower than that of the filter 31, and a winding paper 35 which is present between the filter 31 and the tipping paper 40 and is wound 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 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 winding paper 35, and then wound together with another winding 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１３（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低ろ過部材３３が配置され、連通孔４６０が低ろ過部材３３に対して下流側の領域に設けられてもよい。また、図１３（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低ろ過部材３３が配置され、連通孔４６０が低ろ過部材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. 13(A), a low filtration member 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 low filtration member 33. Also, as shown in FIG. 13(B), a low filtration member 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 low filtration member 33.
