Description

フィルタ、喫煙物品、及び煙流又はエアロゾルに含まれる特定成分を減少させる方法Filters, smoking articles, and methods for reducing specific components in smoke streams or aerosols
 本発明は、フィルタ、喫煙物品、及び煙又はエアロゾルに含まれる特定成分を減少させる方法に関する。 The present invention relates to filters, smoking articles, and methods for reducing specific components contained in smoke or aerosols.
 喫煙時、フィルタ付きシガレット等の喫煙物品のフィルタに水や香喫味に関与する添加物を溶かした水溶液等の液体を染み込ませることで、主流煙における香喫味の特性の改善や、主流煙に異なる香喫味の付加が可能となる。この場合、液体はカプセル内に封入された形態でフィルタ本体内に搭載されており、ユーザは喫煙に先立ち、カプセルを破壊することで、カプセルから液体を噴出させ、フィルタに液体を染み込ませる。 When smoking, by impregnating the filter of smoking articles such as filtered cigarettes with liquid such as water or an aqueous solution containing additives related to flavor, it is possible to improve the flavor characteristics of mainstream smoke or to make it different from mainstream smoke. It is possible to add aromatic flavor. In this case, the liquid is mounted in the filter body in the form of a capsule, and before smoking, the user destroys the capsule to eject the liquid from the capsule and impregnate the filter.
 上記のようなカプセルを搭載したフィルタとして、特許文献1には、筒形状の側面を構成する側壁と、前記筒形状の前後の開口それぞれを閉じる一対の端壁とを有し内部には液体が封入されていると共に、少なくとも前記側壁は弾性変形可能であって、当該側壁に軸線方向に沿って設けた少なくとも1つの直線状のメイン薄肉域を含むカプセルと、前記カプセルを収納する収納空間を含んで形成してある略円筒状のフィルタ本体部とを含むフィルタが開示されている。 Patent Document 1 discloses a filter equipped with a capsule as described above, which has a side wall forming a cylindrical side surface and a pair of end walls that close the front and rear openings of the cylindrical shape, and has a liquid inside. The capsule includes a capsule that is enclosed, and at least the side wall is elastically deformable, and includes at least one linear main thin area provided along the axial direction on the side wall, and a storage space for accommodating the capsule. A filter is disclosed that includes a generally cylindrical filter body formed of a substantially cylindrical filter body.
特許第5984232号Patent No. 5984232
 また、喫煙物品において、加熱式たばこなどの需要が高い要因の一つに喫煙者の健康リスク低減が考えられる。加熱式たばこなどとは異なる従来の燃焼式の喫煙物品においても、フィルタの吸い口から放出される煙流やエアロゾル中に含まれる特定成分を減少させることが要求されることがある。このような特定成分のうち、ベンゾピレンやホルムアルデヒドは除去するのが比較的難しく、これらの化合物を煙流又はエアロゾル中から減少させる有効な手段が求められる。特許文献1に記載のフィルタは、カプセルの潰し易さ(易破壊性)の改善を課題とするものであり、特定成分を減少させることに関しては特許文献1に全く開示がない。
 かかる事情に鑑み、本発明は喫煙物品から放出される煙流又はエアロゾルに含まれる特定成分を減少させるフィルタを提供することを課題とする。
Furthermore, among smoking products, one of the reasons for the high demand for heat-not-burn tobacco products is considered to be the reduction of health risks for smokers. Even in conventional combustion-type smoking articles, which are different from heated cigarettes, it is sometimes required to reduce specific components contained in the smoke stream or aerosol emitted from the mouthpiece of a filter. Among these specific components, benzopyrene and formaldehyde are relatively difficult to remove, and effective means are required to reduce these compounds from smoke streams or aerosols. The filter described in Patent Document 1 aims to improve the crushability (fragility) of capsules, and Patent Document 1 does not disclose anything about reducing specific components.
In view of these circumstances, it is an object of the present invention to provide a filter that reduces specific components contained in smoke streams or aerosols emitted from smoking articles.
 本発明者らは、上記課題を解決するべく鋭意研究した結果、煙流又はエアロゾルを液体と接触させることにより、上記課題を解決できることを知見し、本発明を完成するに至った。本発明の具体的態様は以下のとおりである。 As a result of intensive research aimed at solving the above problems, the present inventors discovered that the above problems could be solved by bringing a smoke stream or aerosol into contact with a liquid, and thus completed the present invention.

 <たばこ充填物>
 たばこ充填物は、後述する加工済たばこ葉が被充填物に所定の態様で充填されたものを指す。「被充填物」とは、加工済たばこ葉が充填される対象であり、たばこ製品の一部である。被充填物としては、巻紙を筒状にしたものや、空気の流入口と流出口とを備える収容体などを挙げることができるが、これらに限定されない。
 加工済たばこ葉が、被充填物に充填される態様としては、加工済たばこ葉が内側となるように巻紙で巻装されることで充填される態様(以下、「たばこロッド」ともいう。)や、加工済たばこ葉が空気の流入口と流出口とを備える収容体の流路に充填される態様(以下、「たばこカートリッジ」ともいう。)等を挙げることができるが、これらに限定されることはない。
<Tobacco filling>
The tobacco filling refers to a material to be filled with processed tobacco leaves, which will be described later, in a predetermined manner. The "material to be filled" is the object to be filled with processed tobacco leaves, and is a part of the tobacco product. Examples of the material to be filled include, but are not limited to, a cylindrical wrapping paper, a container having an air inlet and an air outlet, and the like.
The processed tobacco leaves are filled into the filling material by wrapping the material with wrapping paper so that the processed tobacco leaves are on the inside (hereinafter also referred to as "tobacco rod"). Examples include, but are not limited to, a mode in which processed tobacco leaves are filled into a channel of a container having an air inlet and an air outlet (hereinafter also referred to as a "tobacco cartridge"). It never happens.
 たばこ充填物として、被充填物に充填されたたばこ刻から構成されるたばこ充填物(以下、「第一のたばこ充填物」ともいう)、被充填物に充填されたたばこシートから構成されるたばこ充填物(以下、「第二のたばこ充填物」ともいう)、被充填物に充填されたたばこ顆粒から構成されるたばこ充填物(以下、「第三のたばこ充填物」ともいう)などが挙げられる。 As a tobacco filler, a tobacco filler (hereinafter also referred to as "first tobacco filler") made up of shredded tobacco filled into a stuffed material, and a tobacco made up of tobacco sheets filled into a stuffed stuff. Examples include a filler (hereinafter also referred to as "second tobacco filler"), a tobacco filler consisting of tobacco granules filled in a filling material (hereinafter also referred to as "third tobacco filler"), etc. It will be done.
 <たばこ葉、熟成済たばこ葉、及び加工済たばこ葉>
 本明細書において、「たばこ葉」とは、収穫されたたばこの葉が、後述する熟成を経る前のものの総称である。なお、熟成の一態様にはキュアリングが含まれる。
 これに対して、熟成を経たたばこ葉であって、たばこ製品で利用される種々の形態(後述するたばこ刻や、たばこシート、たばこ顆粒等)に加工される前のものを「熟成済たばこ葉」と称する。さらに、熟成済たばこ葉を、たばこ製品で利用される種々の形態に加工したものを「加工済たばこ葉」と称する。
<Tobacco leaves, aged tobacco leaves, and processed tobacco leaves>
As used herein, "tobacco leaves" is a general term for harvested tobacco leaves before undergoing ripening as described below. Note that one aspect of aging includes curing.
On the other hand, aged tobacco leaves that have not yet been processed into the various forms used in tobacco products (tobacco shreds, tobacco sheets, tobacco granules, etc. to be described later) are referred to as "aged tobacco leaves". ”. Furthermore, aged tobacco leaves that have been processed into various forms used in tobacco products are referred to as "processed tobacco leaves."
 たばこ製品で利用される加工済たばこ葉の形態としては、例えば、熟成済たばこ葉を所定の大きさに刻んだ「たばこ刻」を挙げることができる。また、熟成済たばこ葉を所定の粒径となるように粉砕したもの(以下、「たばこ細粉」ともいう。)を含む組成物を、シート形状に成形して得られる「たばこシート」や、顆粒形状に成形して得られる「たばこ顆粒」を挙げることもできる。なお、前記「たばこ細粉」も加工済たばこ葉の一形態である。 Examples of the form of processed tobacco leaves used in tobacco products include "chopped tobacco," which is obtained by chopping aged tobacco leaves into predetermined sizes. In addition, "tobacco sheets" obtained by forming a composition containing aged tobacco leaves crushed into a predetermined particle size (hereinafter also referred to as "tobacco fine powder") into a sheet shape, "Tobacco granules" obtained by molding into granules can also be mentioned. Note that the above-mentioned "fine tobacco powder" is also a form of processed tobacco leaf.
 たばこ充填物に含まれる加工済たばこ葉の種類は、特に限定されないが、暗色火干種(DFC(Dark Fire Cured))、それ以外の火干種(Fire Cured)、又はこれらのうちの2種以上の混合物を使用することができる。この中でも、スモーキーな香味を付与する観点より、たばこ充填物は、暗色火干種の加工済たばこ葉を含むことが好ましい。 The type of processed tobacco leaf contained in the tobacco filling is not particularly limited, but may be dark fire cured (DFC), other fire cured, or two of these types. Mixtures of the above can be used. Among these, from the viewpoint of imparting a smoky flavor, it is preferable that the tobacco filler contains processed tobacco leaves of dark-colored fireboshi seeds.
 喫煙物品(香味吸引物品)は、従来のシガレットを代表とする燃焼型喫煙物品と非燃焼型喫煙物品とに大別できる。 Smoking articles (flavor suction articles) can be broadly classified into combustible smoking articles, typified by conventional cigarettes, and non-combustible smoking articles.
 <燃焼型喫煙物品>
 燃焼型喫煙物品としては、例えば、シガレット、パイプ、キセル、葉巻、またはシガリロなどが挙げられる。
 燃焼型喫煙物品は、燃焼を伴うたばこ製品であるため、後述するベンゾピレンなどの特定成分が発生しやすい傾向があり、生成したベンゾピレンなどは、燃焼温度の高さ(例えば、最大温度1000℃)の影響から、かなり高い拡散性を有する。理論に縛られるものではないが、本発明においては、煙流又はエアロゾルが水などの液体と接触することにより、急激な温度低下を生じ、特定成分の拡散性が抑えられ、特定成分が液体中に捕捉されるものと推測できる。
<Combustible smoking articles>
Examples of combustible smoking articles include cigarettes, pipes, kissels, cigars, and cigarillos.
Since combustion-type smoking articles are tobacco products that involve combustion, they tend to generate specific components such as benzopyrene, which will be described later. Due to its influence, it has a fairly high diffusivity. Without being bound by theory, in the present invention, contact of the smoke stream or aerosol with a liquid such as water causes a rapid temperature drop, suppresses the diffusivity of specific components, and allows specific components to be absorbed into the liquid. It can be assumed that this is captured by
 以下、図面を参照して、燃焼型喫煙物品のフィルタについて説明する。
 図1Aは、カプセルを搭載したフィルタを、喫煙物品としてのシガレットCGに採用した場合について示している。図1Bは、このシガレットCGが備えるフィルタFL-1に搭載されているカプセルCA-1を取り出して示してある。
Hereinafter, a filter for a combustion type smoking article will be described with reference to the drawings.
FIG. 1A shows a case where a filter equipped with a capsule is employed in a cigarette CG as a smoking article. FIG. 1B shows the capsule CA-1 taken out from the filter FL-1 included in the cigarette CG.
 図1Aで、フィルタ付きのシガレットCGは、タバコ刻みを薄紙で巻いて棒状としてあるシガレット本体100の一端にフィルタFL-1を配置して構成されている。このフィルタFL-1は、可撓性を有したケーシング201の内部に2つの棒状のフィルタ要素202、203により構成されるフィルタ本体部を具備し、ケーシング201は例えばシート材を丸めて端部を接着して筒形状に形成してある。そして、シガレット本体100とフィルタFL-1とは、この両者に掛かるように配置されるチップペーパ101を介して接続されて、1本のフィルタ付きシガレットCGとされている。 In FIG. 1A, a filter-equipped cigarette CG is constructed by disposing a filter FL-1 at one end of a cigarette main body 100, which is a rod-shaped cigarette body 100 made by wrapping shredded tobacco in thin paper. This filter FL-1 includes a filter main body formed by two rod-shaped filter elements 202 and 203 inside a flexible casing 201. It is glued and formed into a cylindrical shape. The cigarette main body 100 and the filter FL-1 are connected via a tip paper 101 disposed so as to cover both of them, thereby forming one filter-equipped cigarette CG.
 上記ケーシング201内には両端に位置するように互いに離間された、第1のフィルタ要素となる第1フィルタ部202と、第2のフィルタ要素となる第2フィルタ部203とが配置されている。これらフィルタ部202、203の材料としては、通常のフィルタ付きシガレットに使用されるフィルタ材料と同様な材料、つまり、アセテート繊維とすることができ、更にチャコールを含んでいてもよい。また、紙フィルタなどを用いることもできる。フィルタ部202、203の材料は同一であっても良いし、異なっていても良い。
 ケーシング201の一方端に位置する第1フィルタ部202はシガレット側となり、他方端に位置する第2フィルタ部203は吸い口を構成している。第1フィルタ部202と第2フィルタ部203とは、上記のように離間して配置され、その間が収納空間204とされており、厳密には第1フィルタ部202と第2フィルタ部203とその間の収納空間204を含んでフィルタ本体部が構成されている。収納空間204の内部にはカプセルCA-1が収容されている。
Inside the casing 201, a first filter section 202 serving as a first filter element and a second filter section 203 serving as a second filter element are arranged at both ends and spaced apart from each other. The filter parts 202 and 203 may be made of the same material as the filter material used in ordinary filtered cigarettes, that is, acetate fibers, and may also contain charcoal. Alternatively, a paper filter or the like can also be used. The materials of the filter parts 202 and 203 may be the same or different.
A first filter section 202 located at one end of the casing 201 serves as a cigarette side, and a second filter section 203 located at the other end constitutes a mouthpiece. The first filter section 202 and the second filter section 203 are arranged apart from each other as described above, and the space between them is the storage space 204. Strictly speaking, the first filter section 202 and the second filter section 203 are arranged apart from each other, and the space between them is the storage space 204. The filter body includes a storage space 204. A capsule CA-1 is housed inside the storage space 204.
 ここで、カプセルCA-1を拡大して示す図1Bも参照すると、カプセルCA-1は概略において中空な筒形状(柱状)であって、その内部には液体が封入されている。
 より詳細には、カプセルCA-1は筒形状の側面を構成する側壁10と、筒形状の前後の開口それぞれを閉じる一対の端壁11、12とを有して内部に液体が封入されている。上記側壁10は少なくとも弾性変形可能な合成材料で形成されている。端壁11、12についても、同じ材料で形成してよいが、筒状をなす側壁10の開口を確実に閉塞できる材料であれば特に限定する必要はない。
 側壁10を構成するのに、好適な合成材料としては例えばポリエチレン、ポリプロピレン、ポリ塩化ビニル、ポリスチレン、ポリエチレンテレフタレート、ポリビニルアルコール及びポリアミドからなる群から選択される何れかである食品用のプラスチック素材を用いるのが望ましい。
 また、上記端壁11、12については側壁と同じ材料を用いてよいが、ラミネートフィルムなどのフィルム材として、ヒートシールで開口を閉じるようにしてもよい。このようなシールフィルムを採用する場合には、熱可塑性の接着剤によって、側壁の開口縁に接着すればよい。この接着剤としては、例えば、接着性ポリオレフィン樹脂、低分子量ポリエチレン及びEVA(エチレンビニルアルコール)を主剤とするホットメルト接着剤等を使用できる。
Here, referring also to FIG. 1B showing an enlarged view of the capsule CA-1, the capsule CA-1 has a generally hollow cylindrical shape (column shape), and a liquid is sealed inside the capsule CA-1.
More specifically, the capsule CA-1 has a side wall 10 forming a cylindrical side surface and a pair of end walls 11 and 12 that close the front and rear openings of the cylindrical shape, and a liquid is sealed inside. . The side wall 10 is made of at least an elastically deformable synthetic material. The end walls 11 and 12 may also be made of the same material, but there is no need for any particular limitation as long as the material can reliably close the opening of the cylindrical side wall 10.
A suitable synthetic material for constructing the side wall 10 is, for example, a food grade plastic material selected from the group consisting of polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyethylene terephthalate, polyvinyl alcohol and polyamide. is desirable.
Further, the end walls 11 and 12 may be made of the same material as the side walls, but they may also be made of a film material such as a laminate film and the openings may be closed by heat sealing. When such a sealing film is employed, it may be adhered to the opening edge of the side wall using a thermoplastic adhesive. As this adhesive, for example, a hot melt adhesive whose main ingredients are adhesive polyolefin resin, low molecular weight polyethylene, and EVA (ethylene vinyl alcohol) can be used.
 そして、カプセルCA-1内に封入する液体としては、シガレットの喫味を改善できるものを適宜に選択して採用すればよく、特に限定はないが、例えば単なる水、水に親水性のフレーバ、疎水性のフレーバのいずれも採用できる。疎水性のフレーバの場合には乳化された状態で配合してもよいし、プロピレングリコールやエタノールなどの溶媒を用いてもよい。より具体的には、上記液体として例えば、水に砂糖、たばこエキス、香料等を溶解させた溶液、またはブランデー等の水を基体とする溶液を採用することができる。また、必要により、変質防止の薬液などを混ぜてもよい。更に、上記液体として、香料を包摂したマイクロカプセル(香料カプセル)のような微小固体などを採用してもよく、更に液体として水液中に上記香料カプセルを浮遊させた形態などにしてもよい。
 なお、上記ケーシング201とチップペーパ101との少なくとも一方に、耐水機能を備えたシート材を採用して、上記液体が外周部に漏れるのを防止する構造を備えたものとするのが好ましい。
The liquid to be sealed in the capsule CA-1 may be appropriately selected from those that can improve the smoking taste of the cigarette, and is not particularly limited. Any gender flavor can be used. In the case of hydrophobic flavors, they may be blended in an emulsified state, or a solvent such as propylene glycol or ethanol may be used. More specifically, as the liquid, for example, a solution in which sugar, tobacco extract, fragrance, etc. are dissolved in water, or a water-based solution such as brandy can be employed. Further, if necessary, a chemical solution for preventing deterioration may be mixed. Further, the liquid may be a fine solid such as a microcapsule (fragrance capsule) containing a fragrance, or the liquid may be in the form of the fragrance capsule suspended in an aqueous liquid.
Note that it is preferable that at least one of the casing 201 and the tip paper 101 be made of a sheet material having a water-resistant function to have a structure that prevents the liquid from leaking to the outer periphery.
 このシガレットCGに採用するフィルタFL-1にあっては、ユーザによる外力(フィルタ部分を指で摘むような力)を受けたときに、容易に破壊するカプセルCA-1が搭載してある。
 前述したようにフィルタFL-1はシガレット本体100に対応して棒状(略円筒状)であり、フィルタ部202、203の間の収納空間204にカプセルCA-1が配置されている。そして、図1Aの矢印Fで示すように、フィルタを半径方向に摘む動作で外力が印加される。カプセルCA-1がこの外力を受けたときに、容易に破壊するように側壁10は易破壊構造としてある、具体的には後述の薄肉域が設けてある。薄肉域は応力を受けた他の部分より破壊し易くするため、他の領域よりも薄肉に形成した領域であり、例えばV字溝などとして形成した溝部である。
The filter FL-1 used in this cigarette CG is equipped with a capsule CA-1 that easily breaks when subjected to an external force from the user (such as a force such as pinching the filter part with one's fingers).
As described above, the filter FL-1 has a rod shape (approximately cylindrical shape) corresponding to the cigarette body 100, and the capsule CA-1 is arranged in the storage space 204 between the filter parts 202 and 203. Then, as shown by arrow F in FIG. 1A, an external force is applied by the action of pinching the filter in the radial direction. The side wall 10 has an easy-to-destruct structure so that it can be easily destroyed when the capsule CA-1 is subjected to this external force, specifically, it is provided with a thin-walled area, which will be described later. The thin region is a region formed thinner than other regions in order to be more easily broken than other regions subjected to stress, and is, for example, a groove portion formed as a V-shaped groove.
 図1A、Bで例示するカプセルCA-1の側壁10には、周方向に沿って環状であり、これを線状に設けた環線状のメイン薄肉域10aが少なくとも1つ(図1A、Bでは4つ)設けてあるものである。そして、図1Aで示しているように筒状であるカプセルCA-1は、空間204内に寝かせ姿勢でセットされている。
 これにより、環線状の薄肉域10aが延在する方向は、フィルタFL-1を半径方向に摘むような動作で外力Fが印加されたときに、その外力Fが加わる方向と平行となる。
The side wall 10 of the capsule CA-1 illustrated in FIGS. 1A and B has at least one annular main thin-walled area 10a that is annular along the circumferential direction and provided in a linear manner (in FIGS. 1A and B). 4) It is provided. As shown in FIG. 1A, the cylindrical capsule CA-1 is set in the space 204 in a lying position.
As a result, the direction in which the annular thin area 10a extends is parallel to the direction in which the external force F is applied when the filter FL-1 is pinched in the radial direction.
 図2は、カプセルCA-1に外力Fを作用させたときの様子を模式的に示した図である。
 カプセルCA-1の側壁10には外力Fが作用する方向と平行にメイン薄肉域10a(例示は4つ)が設けてある。このようなメイン薄肉域10aが設けてあると、外力を加えると変形が進み、屈曲して応力が集中する折り曲り部分13の応力が一定以上になると図で示すように破断する。外力Fが作用するとカプセルCA-1内の圧力が上昇し、そのため、カプセルCA-1は外力Fに対して垂直に延びる方向にも力が発生する。そのため、外力Fに対して平行にあるメイン薄肉域10aは容易に破断する。
FIG. 2 is a diagram schematically showing the state when external force F is applied to capsule CA-1.
Main thin-walled regions 10a (four in the example) are provided on the side wall 10 of the capsule CA-1 in parallel to the direction in which the external force F acts. If such a main thin-walled region 10a is provided, deformation progresses when external force is applied, and when the stress at the bent portion 13, where stress is concentrated due to bending, exceeds a certain level, the main thin-walled region 10a breaks as shown in the figure. When the external force F acts, the pressure inside the capsule CA-1 increases, so that a force is also generated in the capsule CA-1 in a direction extending perpendicular to the external force F. Therefore, the main thin area 10a that is parallel to the external force F is easily broken.
 図3は、環線状のメイン薄肉域10aに対して、これと垂直な方向に形成した直線状のサブ薄肉域10bを更に設けた改善例を示している。メイン薄肉域10aが環線状であるのに対して、サブ薄肉域10bはメイン薄肉域10aが形成されている周方向と垂直な軸線CL方向に延在する直線状となる。このようにサブ(補助)の薄肉域10bを形成しておくと、カプセルCA-1を更に破壊し易い構造とすることができる。 FIG. 3 shows an improved example in which a linear sub-thin area 10b is further provided in a direction perpendicular to the annular main thin area 10a. While the main thin area 10a is annular, the sub thin area 10b is linear extending in the direction of the axis CL perpendicular to the circumferential direction in which the main thin area 10a is formed. By forming the sub (auxiliary) thin-walled region 10b in this manner, the capsule CA-1 can be structured to be more easily destroyed.
 なお、上記メイン薄肉域10aや直線状のサブ薄肉域10bは、必ずしも連続しているライン状の領域とする必要はない。すなわち、一部に薄肉域を設けない部分(不連続部)を含むような不連続に形成してもよい。図4は環線状のメイン薄肉域10aに不連続部14を設けた場合を例示している。
 なお、図3に示した、メイン薄肉域10aおよびサブ薄肉域10bを含む形態の場合についても同様に不連続部を形成してよい。この場合、メイン薄肉域10aとサブ薄肉域10bのいずれか一方としてもよいし、両方としてもよい。
 更に、不連続とする形態にも限定はない、例えば規則的な破断線状としてもよいし、破断位置が不規則な破断線状としてもよい。
Note that the main thin area 10a and the linear sub-thin area 10b do not necessarily have to be continuous linear areas. That is, it may be formed discontinuously, including a portion (discontinuous portion) in which no thin-walled region is provided. FIG. 4 illustrates a case where a discontinuous portion 14 is provided in the annular main thin area 10a.
Note that a discontinuous portion may be formed in the same manner in the case of the configuration including the main thin area 10a and the sub thin area 10b shown in FIG. In this case, either the main thin area 10a or the sub-thin area 10b may be used, or both may be used.
Furthermore, there is no limitation to the form of discontinuity; for example, it may be in the form of regular broken lines, or it may be in the form of broken lines with irregular break positions.
 以下では、第1の実施形態のカプセルCA-2を搭載するフィルタFL-2をシガレットCGに採用した場合について、更に図を参照して説明する。ただし、先に説明済みの部分については同一の符号を付すことにより重複説明を省略し、相違する部分を中心に説明する。
 図5Aは、前記フィルタFL-2を、シガレットCGに採用した場合の例を示している。図5BはフィルタFL-2に搭載されているカプセルCA-2を取り出して示してある。
Below, the case where the filter FL-2 equipped with the capsule CA-2 of the first embodiment is adopted as a cigarette CG will be explained with further reference to the drawings. However, the parts that have already been explained will be given the same reference numerals to omit redundant explanation, and the explanation will focus on the different parts.
FIG. 5A shows an example in which the filter FL-2 is applied to a cigarette CG. FIG. 5B shows the capsule CA-2 mounted on the filter FL-2 taken out.
 図5A、Bで例示するカプセルCA-2にあっては、筒状となる側壁10の軸線CL方向(周方向と垂直)に沿って設けた少なくとも1つの直線状のメイン薄肉域10cが設けてあるものである。そして、図5Aで示しているように筒状であるカプセルCA-2は、空間204内に立ち姿勢にてセットされている。
 これにより、直線状の薄肉域10cが延在する方向は、フィルタFLに半径方向に摘むような動作で外力Fが印加されたときに、その外力が加わる方向と平行となるようにしてある。
In the capsule CA-2 illustrated in FIGS. 5A and 5B, at least one linear main thin region 10c is provided along the axis CL direction (perpendicular to the circumferential direction) of the side wall 10 having a cylindrical shape. It is something. As shown in FIG. 5A, the cylindrical capsule CA-2 is set in the space 204 in a standing position.
Thereby, the direction in which the linear thin region 10c extends is parallel to the direction in which the external force is applied when the external force F is applied to the filter FL by a radial pinching motion.
 図6は、カプセルCA-2に外力Fを作用させたときの様子を模式的に示した図である。
 上記のようにカプセルCA-2の側壁10には、外力Fが作用する方向と平行にメイン薄肉域10cが設けてある。このようなメイン薄肉域10cが設けてあると、外力を加えて変形が進み、応力が一定以上になると図で示すように最も屈曲して応力が集中する折り曲り部分13で破断する。外力Fが作用するとカプセルCA-2内の圧力が上昇し、そのため、カプセルCA-2は外力Fに対して垂直に延びる方向にも力が発生する。そのため、外力Fに対して平行にあるメイン薄肉域10cは容易に破断する。
 なお、本例の場合には、収納空間204内でのカプセルCA-2の位置を視認できるようにしておくのがよい。例えば、上記収納空間204を含んでフィルタ本体部を覆うケーシング201を透明性のシート材とし、収納空間204を視認可能とする。更に、その外側を覆うチップペーパ101についても同様に透明なシート材とする。このようにすれば、ユーザはカプセルCA-2の位置を確認して、押し潰すことができる。
 その際、ユーザが押す場所を確認できるように、例えば図6に示すように「PUSH」などの文字を付したり、これが小さ過ぎて読めない場合には何らかの目印(押す面を赤、青などカラーとしておくなど)を付加しておくのが望ましい。
FIG. 6 is a diagram schematically showing the state when external force F is applied to capsule CA-2.
As described above, the side wall 10 of the capsule CA-2 is provided with the main thin area 10c parallel to the direction in which the external force F acts. If such a main thin area 10c is provided, deformation progresses by applying external force, and when the stress exceeds a certain level, the main thin area 10c bends the most and breaks at the bent portion 13 where stress is concentrated, as shown in the figure. When the external force F acts, the pressure inside the capsule CA-2 increases, so that a force is also generated in the capsule CA-2 in a direction extending perpendicular to the external force F. Therefore, the main thin region 10c parallel to the external force F is easily broken.
In this example, it is preferable to make the position of the capsule CA-2 within the storage space 204 visible. For example, the casing 201 that includes the storage space 204 and covers the filter main body is made of a transparent sheet material so that the storage space 204 can be visually recognized. Furthermore, the chip paper 101 covering the outside thereof is also made of a transparent sheet material. In this way, the user can confirm the position of the capsule CA-2 and crush it.
At that time, so that the user can confirm where to press, for example, as shown in Figure 6, the characters such as ``PUSH'' may be attached, or if this is too small to read, some kind of landmark (such as red or blue on the side to be pressed) may be added. It is desirable to add a color (e.g. in color).
 図7は、直線状のメイン薄肉域10cに対して、これと垂直な方向に形成した環線状のサブ薄肉域10dを更に設けた改善例を示している。本例の場合は、メイン薄肉域10cが軸線CL方向に延在する直線状であり、サブ薄肉域10dが環線状となる。このようにサブ(補助)の薄肉域10dを形成しておくと、カプセルCA-2を更に破壊し易い構造とすることができる。
 なお、第1の実施形態の場合も、メイン薄肉域10cや環線状のサブ薄肉域10dは、必ずしも連続したライン状の領域とする必要はない。すなわち、前述したように一部に不連続部分を含むような不連続形態としてもよい。
FIG. 7 shows an improved example in which an annular sub-thin area 10d is further provided in a direction perpendicular to the linear main thin area 10c. In this example, the main thin area 10c has a linear shape extending in the direction of the axis CL, and the sub thin area 10d has an annular shape. By forming the sub (auxiliary) thin-walled region 10d in this manner, the capsule CA-2 can be structured to be more easily destroyed.
In addition, also in the case of the first embodiment, the main thin area 10c and the annular sub-thin area 10d do not necessarily have to be continuous linear areas. That is, as described above, it may have a discontinuous form including a discontinuous portion.
 更に、第1の実施形態について、好ましい変形例を図8を参照して説明する。
 図5A、Bに例示したカプセルCA-2は円柱状であってその側壁10に環線状の薄肉域を設ける場合で、これを立姿勢でセットするものであった。
 しかし、カプセルCA-2は円柱状に限らず、例えば図8に示すように角柱状(ここでは四角柱(直方体)としてある)であるカプセルCA-3としてもよい。角柱とすることで収納空間204内での姿勢を安定化させることができる。この場合、4つの側壁に薄肉域10cが形成される。このようなカプセルCA-3は軸線方向と側壁とが平行となるように収納空間204内に配置すれば前後・左右の側壁となるが、これに限らず図8で示すように角部を前に突出させるような立ち姿勢として収納空間204内に配置してもよい。
 なお、各カプセルCA(CA-1、CA-2、CA-3)の位置をより確実に安定させるために、必要に応じてフィルタ要素に用いた繊維などを流用して収納空間204内での隙間を埋めて位置ずれを防止する様にしてもよい。また、上記ケーシング201の内面に位置決め用の突起部を付加し、この突起部でカプセルCAを周囲から押さえ位置決めするなどの構造を採用してもよい。このようにカプセルCAの位置を安定させた場合、第1フィルタ部、第2フィルタ部の一方もしくは両方は必ずしも必要ではない。この点に関して前述した実施例では、第1フィルタ部と第2フィルタ部との間に形成した空間を、フィルタ本体部内の収納空間として利用する場合を説明している。しかし、これは好適例であって、収納空間の形態はこれに限らないということである。
Furthermore, a preferred modification of the first embodiment will be described with reference to FIG. 8.
The capsule CA-2 illustrated in FIGS. 5A and 5B has a cylindrical shape with an annular thin area on its side wall 10, and is set in an upright position.
However, the capsule CA-2 is not limited to a cylindrical shape, and may be, for example, a prismatic capsule CA-3 (here, a square prism (rectangular parallelepiped)) as shown in FIG. By making it a prismatic shape, the posture within the storage space 204 can be stabilized. In this case, thin areas 10c are formed on the four side walls. If such a capsule CA-3 is arranged in the storage space 204 so that the axial direction and the side walls are parallel, it will become the front and rear, left and right side walls, but the present invention is not limited to this. It may be placed in the storage space 204 in a standing position such that it protrudes.
In addition, in order to more reliably stabilize the position of each capsule CA (CA-1, CA-2, CA-3), the fibers used for the filter element may be used to stabilize the position within the storage space 204 as necessary. The gaps may be filled to prevent misalignment. Further, a structure may be adopted in which a positioning protrusion is added to the inner surface of the casing 201, and the capsule CA is held and positioned by the protrusion from the periphery. When the position of the capsule CA is stabilized in this way, one or both of the first filter section and the second filter section are not necessarily required. Regarding this point, in the embodiments described above, a case has been described in which the space formed between the first filter part and the second filter part is used as a storage space within the filter main body part. However, this is a preferred example, and the form of the storage space is not limited to this.
 上記フィルタ付きシガレットCGを喫煙するユーザ(喫煙者)による動作を説明する。ユーザは、図1Aの矢印Fで示されるように、フィルタFLの中央部を指で挟み、これを押し潰すように外部から力を加えると、フィルタFLのケーシング201並びに、その内部のカプセルCA-1は弾性変形される。カプセルCA-1は破壊容易に設定してあるので、簡単に破壊して液体が流出してフィルタに吸収されることができる。
 この後、ユーザはフィルタ付きシガレットCGに火をつけて喫煙することになる。上記液体によって、シガレットからの煙流中に含まれる水溶性成分を減少させることができ、また添加されているフレーバにより香喫味が改善される。
An operation performed by a user (smoker) who smokes the filter-equipped cigarette CG will be described. As shown by the arrow F in FIG. 1A, when the user pinches the center of the filter FL with his fingers and applies force from the outside to crush it, the casing 201 of the filter FL and the capsule CA- 1 is elastically deformed. Since the capsule CA-1 is designed to be easily broken, it can be easily broken and the liquid can flow out and be absorbed into the filter.
After this, the user lights the filter-equipped cigarette CG and smokes it. The liquid can reduce the water-soluble components contained in the smoke stream from the cigarette, and the added flavor can improve the aromatic taste.

<Non-combustion heated smoking article (heated smoking article)>
A non-combustion heating type smoking article (heating type smoking article) may be heated by a heating device that is separate from the article, or may be heated by a heating device that is integrated with the article. In the former smoking article (separate type), the non-combustion heating type smoking article and the heating device are collectively referred to as a "non-combustion heating type smoking system." An example of a non-combustion heating smoking system will be described below with reference to FIGS. 9 and 10.
 図9は、非燃焼加熱型喫煙システムの一例を示す断面模式図であり、非燃焼加熱型喫煙物品40の喫煙用セグメント40A内に、ヒータ32を挿入する前の状態を示す。使用時には、喫煙用セグメント40A内に、ヒータ32が挿入される。図10は、非燃焼加熱型喫煙物品40の断面図である。 FIG. 9 is a schematic cross-sectional view showing an example of a non-combustion heating type smoking system, and shows a state before the heater 32 is inserted into the smoking segment 40A of the non-combustion heating type smoking article 40.

More preferred. The cross-sectional shape of the smoking segment 40A is not particularly limited, but may be, for example, circular, oval, polygonal, or the like.
 喫煙用セグメント40Aは、喫煙用組成物シートまたはこれに由来する材料41と、その周囲に巻かれたラッパー42とを有する。 The smoking segment 40A has a smoking composition sheet or material 41 derived therefrom, and a wrapper 42 wrapped around it.
 フィルター部40Cは、円柱形をなしている。フィルター部40Cは、酢酸セルロースアセテート繊維が充填されて構成されたロッド状の第1セグメント45と、同じく酢酸セルロースアセテート繊維が充填されて構成されたロッド状の第2セグメント46とを有する。第1セグメント45は、喫煙用セグメント40A側に位置している。第1セグメント45は、中空部を有していてもよい。第2セグメント46は、吸口側に位置している。第2セグメント46は、中実である。第1セグメント45は、第1充填層(酢酸セルロースアセテート繊維)45aと、第1充填層45aの周囲に巻かれたインナープラグラッパー45bとにより構成される。第2セグメント46は、第2充填層(酢酸セルロースアセテート繊維)46aと、第2充填層46aの周囲に巻かれたインナープラグラッパー46bとにより構成される。第1セグメント45および第2セグメント46は、アウタープラグラッパー47によって連結されている。アウタープラグラッパー47は、酢酸ビニルエマルジョン系接着剤等によって第1セグメント45および第2セグメント46に接着されている。 The filter section 40C has a cylindrical shape. The filter section 40C has a rod-shaped first segment 45 filled with cellulose acetate acetate fibers and a rod-shaped second segment 46 filled with cellulose acetate acetate fibers. The first segment 45 is located on the smoking segment 40A side. The first segment 45 may have a hollow portion. The second segment 46 is located on the mouthpiece side. Second segment 46 is solid. The first segment 45 includes a first filling layer (cellulose acetate acetate fiber) 45a and an inner plug wrapper 45b wound around the first filling layer 45a. The second segment 46 includes a second filling layer (cellulose acetate acetate fiber) 46a and an inner plug wrapper 46b wound around the second filling layer 46a. The first segment 45 and the second segment 46 are connected by an outer plug wrapper 47. The outer plug wrapper 47 is bonded to the first segment 45 and the second segment 46 using a vinyl acetate emulsion adhesive or the like.
 フィルター部40Cの長さを例えば10~30mm、連結部40Bの長さを例えば10~30mm、第1セグメント45の長さを例えば5~15mm、第2セグメント46の長さを例えば5~15mmとすることができる。これら個々のセグメントの長さは、一例であり、製造適性、要求品質、喫煙用セグメント40Aの長さ等に応じて、適宜変更できる。 The length of the filter portion 40C is, for example, 10 to 30 mm, the length of the connecting portion 40B is, for example, 10 to 30 mm, the length of the first segment 45 is, for example, 5 to 15 mm, and the length of the second segment 46 is, for example, 5 to 15 mm. can do. The lengths of these individual segments are just examples, and can be changed as appropriate depending on manufacturing suitability, required quality, length of the smoking segment 40A, and the like.
 例えば、第1セグメント45(センターホールセグメント)は、1つまたは複数の中空部を有する第1充填層45aと、第1充填層45aを覆うインナープラグラッパー45bとで構成される。第1セグメント45は、第2セグメント46の強度を高める機能を有する。第1セグメント45の第1充填層45aは、例えば酢酸セルロース繊維が高密度で充填されている。この酢酸セルロース繊維には、トリアセチンを含む可塑剤が酢酸セルロースの質量に対して、例えば6~20質量%添加されて硬化されている。第1セグメント45の中空部は、例えば内径φ1.0~φ5.0mmである。 For example, the first segment 45 (center hole segment) is composed of a first filling layer 45a having one or more hollow parts and an inner plug wrapper 45b covering the first filling layer 45a. The first segment 45 has the function of increasing the strength of the second segment 46. The first packed layer 45a of the first segment 45 is filled with, for example, cellulose acetate fibers at a high density. A plasticizer containing triacetin is added to the cellulose acetate fiber in an amount of, for example, 6 to 20% by mass based on the mass of the cellulose acetate, and the fiber is cured. The hollow portion of the first segment 45 has an inner diameter of φ1.0 to φ5.0 mm, for example.
 第1セグメント45の第1充填層45aは、例えば、比較的に高い繊維充填密度で構成されてもよく、あるいは後述する第2セグメント46の第2充填層46aの繊維充填密度と同等であってもよい。このため、吸引時には、空気やエアロゾルが中空部のみを流れることになり、第1充填層45aには空気やエアロゾルがほとんど流れない。例えば、第2セグメント46において、エアロゾル成分の濾過による減少を少なくしたい場合には、例えば第2セグメント46の長さを短くして、その分だけ第1セグメント45を長くすることもできる。 The first packed layer 45a of the first segment 45 may have a relatively high fiber packing density, or may have a fiber packing density equivalent to that of a second packed layer 46a of the second segment 46, which will be described later. Good too. Therefore, during suction, air or aerosol flows only through the hollow portion, and almost no air or aerosol flows into the first packed layer 45a. For example, if it is desired to reduce the reduction of aerosol components due to filtration in the second segment 46, the length of the second segment 46 can be shortened, and the first segment 45 can be lengthened by that amount.
 短縮した第2セグメント46を第1セグメント45で置き換えることは、エアロゾル成分のデリバリー量を増大させるために有効である。第1セグメント45の第1充填層45aが繊維充填層であることから、使用時の外側からの触り心地は、使用者に違和感を生じさせることがない。 Replacing the shortened second segment 46 with the first segment 45 is effective for increasing the amount of aerosol component delivered. Since the first filled layer 45a of the first segment 45 is a fiber filled layer, the user will not feel uncomfortable when using the device from the outside.
 第2セグメント46は、第2充填層46aと、第2充填層46aを覆うインナープラグラッパー46bとで構成される。第2セグメント46(フィルターセグメント)は、酢酸セルロース繊維が一般的な密度で充填されており、一般的なエアロゾル成分の濾過性能を有する。 The second segment 46 is composed of a second filling layer 46a and an inner plug wrapper 46b that covers the second filling layer 46a. The second segment 46 (filter segment) is filled with cellulose acetate fibers at a typical density and has typical aerosol component filtration performance.
 第1セグメント45と第2セグメント46との間で、喫煙用セグメント40Aから放出されるエアロゾル(主流煙)をろ過するろ過性能を異ならせてもよい。第1セグメント45および第2セグメント46の少なくとも一方に、香料を含ませてもよい。フィルター部40Cの構造は任意であり、上記のような複数のセグメントを有する構造であってもよいし、単一のセグメントによって構成されていてもよい。またフィルター部40Cは、1つのセグメントで構成されてもよい。この場合、フィルター部40Cは、第1セグメントまたは第2セグメントのいずれで構成されていてもよい。 The first segment 45 and the second segment 46 may have different filtration performance for filtering the aerosol (mainstream smoke) released from the smoking segment 40A. At least one of the first segment 45 and the second segment 46 may contain a fragrance. The structure of the filter section 40C is arbitrary, and may have a structure having a plurality of segments as described above, or may be composed of a single segment. Further, the filter section 40C may be composed of one segment. In this case, the filter section 40C may be composed of either the first segment or the second segment.
 連結部40Bは、円筒形をなしている。連結部40Bは、例えば厚紙等によって円筒形に形成された紙管43を有する。連結部40Bには、エアロゾルを冷却するための冷却部材が充填されていてもよい。冷却部材としては、ポリ乳酸等のポリマーのシートが挙げられ、当該シートを折り畳んで充填することができる。さらに、喫煙用セグメント40Aと連結部40Bの間には、喫煙用セグメント40Aの位置が変動することを抑制する支持部が設けられていてもよい。支持部は、第1セグメント45のようなセンタホールフィルター等の公知の材料で構成できる。 The connecting portion 40B has a cylindrical shape. The connecting portion 40B has a paper tube 43 formed in a cylindrical shape, for example, from cardboard or the like. The connecting portion 40B may be filled with a cooling member for cooling the aerosol. Examples of the cooling member include a sheet of polymer such as polylactic acid, and the sheet can be folded and filled. Furthermore, a support part that suppresses the position of the smoking segment 40A from changing may be provided between the smoking segment 40A and the connecting part 40B. The support portion can be constructed of a known material such as a center hole filter such as the first segment 45.
 ラッパー48は、喫煙用セグメント40A、連結部40B、およびフィルター部40Cの外側に円筒形に巻かれて、これらを一体的に連結している。ラッパー48の一方の面(内面)には、通気孔部44の付近を除く全面または略全面に酢酸ビニルエマルジョン系接着剤が塗布されている。複数の通気孔部44は、ラッパー48によって、喫煙用セグメント40A、連結部40B、およびフィルター部40Cが一体にされた後に、外側からレーザ加工を施して形成される。 The wrapper 48 is wrapped around the smoking segment 40A, the connecting portion 40B, and the filter portion 40C in a cylindrical shape to integrally connect them. A vinyl acetate emulsion adhesive is applied to one surface (inner surface) of the wrapper 48 over the entire surface or substantially the entire surface except for the vicinity of the ventilation hole portion 44 . The plurality of ventilation holes 44 are formed by laser processing from the outside after the smoking segment 40A, the connecting part 40B, and the filter part 40C are integrated by the wrapper 48.
 通気孔部44は、連結部40Bを厚み方向に貫通するように2以上の貫通孔を有する。2以上の貫通孔は、喫煙物品40の中心軸の延長線上から見て、放射状に配置するように形成される。本実施形態では、通気孔部44は、連結部40Bに設けられているが、フィルター部40Cに設けられていてもよい。また、本実施形態では、通気孔部44の2以上の貫通孔は、1つの円環上に一定間隔を空けて1列に並んで設けられるが、2つの円環上に一定の間隔を空けて2列に並んで設けられていてもよいし、1列または2列の通気孔部44が不連続または不規則に並んで設けられていてもよい。ユーザが吸口を咥えて吸引する際に、通気孔部44を介して主流煙中に外気が取り込まれる。ただし、通気孔部44は設けられていなくてもよい。 The ventilation hole portion 44 has two or more through holes that penetrate the connecting portion 40B in the thickness direction. The two or more through holes are formed so as to be arranged radially when viewed from an extension of the central axis of the smoking article 40. In this embodiment, the ventilation hole portion 44 is provided in the connecting portion 40B, but may be provided in the filter portion 40C. Furthermore, in the present embodiment, two or more through holes of the ventilation hole section 44 are provided in a row on one ring at a certain interval, but they are arranged on two rings at a certain interval. The ventilation holes 44 may be arranged in two rows, or one or two rows of ventilation holes 44 may be arranged discontinuously or irregularly.

The obtained extract was filtered with a syringe filter (pore size: 0.45 μm, MF-Millipore (product name), manufactured by Merck Millipore), and the obtained filtrate was passed through a fully automatic solid phase extraction device (after silica cartridge + NH2 cartridge). Turbo VAP) and then dissolved in 1 ml of acetonitrile. Using the obtained solution, benzo[a]pyrene was measured/quantified using LC-FLD (fluorescence detector) (column: X-Bridge C18, 4.6 mm x 150 mm, 3.5 μm).
 得られた分析結果(1パフ当たりの各成分の捕集量)を表1に示す。また、下記に示した式に基づいて算出した各成分の減少率も表1に示す。 The obtained analysis results (amount of each component collected per puff) are shown in Table 1. Table 1 also shows the reduction rate of each component calculated based on the formula shown below.

 表1の結果より、燃焼型タバコ品(1R6F)から発生させた主流煙を水に通すことにより、NNN、NNK、ホルムアルデヒド、アセトアルデヒド、アクロレイン、及びベンゾ[a]ピレンの各特定成分に関して、煙に含まれる量を減少できることがわかった。特にこれまで除去するのが比較的難しく、有効な除去手段がなかった、ベンゾ[a]ピレンやホルムアルデヒドに関しても、水に通すことにより確実に除去できることがわかった。また、主流煙を水に通すことにより、TSNAであるNNN及びNNKも確実に除去できており、この点でも有用であることがわかった。 From the results in Table 1, by passing mainstream smoke generated from a combustible tobacco product (1R6F) through water, it was found that the specific components of NNN, NNK, formaldehyde, acetaldehyde, acrolein, and benzo[a]pyrene were It was found that the amount contained could be reduced. In particular, it has been found that benzo[a]pyrene and formaldehyde, which have been relatively difficult to remove and for which no effective means have been available, can be reliably removed by passing them through water. Furthermore, by passing the mainstream smoke through water, NNN and NNK, which are TSNAs, were also reliably removed, which proved to be useful in this respect as well.
 主流煙を水に通した形態の表1の結果に基づくと、液体を封入したカプセルを含むフィルタを使用して、カプセルの少なくとも一部を破壊して、主流煙を液体が浸透したフィルタを通過させた場合でも、同様に各特定成分を減少できると考えられる。 Based on the results in Table 1 for the mainstream smoke-through-water configuration, a filter containing a liquid-filled capsule is used, at least a portion of the capsule is destroyed, and the mainstream smoke is passed through the liquid-filled filter. It is considered that each specific component can be similarly reduced even if
 以上より、本発明のフィルタは、喫煙物品から放出される煙流又はエアロゾルに含まれる特定成分を減少させることができるとわかる。 From the above, it can be seen that the filter of the present invention can reduce specific components contained in smoke streams or aerosols emitted from smoking articles.
