　本発明の目的は、従来のシガレットフィルターでは達成できなかった外観品質を有する喫煙物品用フィルターを提供することにある。 An object of the present invention is to provide a filter for smoking articles having an appearance quality that cannot be achieved by a conventional cigarette filter.
　本発明では、上記課題を解決するために以下の手段を採用する。本発明に係る喫煙物品用フィルターは、円柱状の濾材を含むフィルター部と、前記フィルター部の外周を覆う第１の包装紙と、前記第１の包装紙の外周を覆う第２の包装紙と、前記第２の包装紙に設けられた複数の光透過部と、を備え、前記第１の包装紙の外周面には、複数の画像が合成された複合画像で構成された下絵が配置され、前記第１の包装紙と第２の包装紙とは、所定方向への相対変位が可能であって、前記第１の包装紙と第２の包装紙とが相対変位した際に、該第２の包装紙における前記複数の光透過部を通じて前記下絵が視認可能に構成されている。 In the present invention, the following means are adopted in order to solve the above problems. The filter for smoking articles according to the present invention includes a filter part including a columnar filter medium, a first wrapping paper covering the outer periphery of the filter part, and a second wrapping paper covering the outer periphery of the first wrapping paper. A plurality of light transmitting portions provided on the second wrapping paper, and an outer surface of the first wrapping paper is provided with a sketch composed of a composite image obtained by combining a plurality of images. The first wrapping paper and the second wrapping paper are capable of relative displacement in a predetermined direction, and when the first wrapping paper and the second wrapping paper are relatively displaced, The background image is configured to be visible through the plurality of light transmitting portions of the wrapping paper of No. 2.
　この構成によれば、喫煙者が、第１の包装紙および第２の包装紙を所定の方向へ相対変位させる操作を行った際に、第２の包装紙における複数の光透過部を通じて、第１の包装紙の下絵に係る複合画像を喫煙者に視認させることができるため、スリットアニメーションを生じさせる視覚的効果が得られる。これにより、従来では達成できなかった外観品質を有する喫煙物品用フィルターを提供することができる。 According to this configuration, when the smoker performs an operation of relatively displacing the first wrapping paper and the second wrapping paper in a predetermined direction, the plurality of light transmissive portions in the second wrapping paper are used to pass through the first wrapping paper. Since it is possible for a smoker to visually recognize a composite image related to the sketch of one wrapping paper, a visual effect that causes a slit animation is obtained. Thereby, the filter for smoking articles which has the external appearance quality which could not be achieved conventionally can be provided.
　また、第１の包装紙と第２の包装紙とは、フィルター長手軸を中心とした相対回動が可能に構成されていてもよい。また、フィルター部は、フィルター長手方向において相対的に上流側に位置する上流フィルター部と、該上流フィルター部の下流側に位置する下流フィルター部とを含み、第１の包装紙は、上流フィルター部の外周に巻かれ、且つ、タバコ刻を含むタバコロッドと上流フィルター部とを一体に巻き取り、第２の包装紙は、下流フィルター部の外周に巻かれていてもよい。この場合、上流フィルター部と下流フィルター部とは、少なくとも所定の範囲内でフィルター長手軸を中心とした相対回動が自在であってもよい。 Further, the first wrapping paper and the second wrapping paper may be configured to be capable of relative rotation around the filter longitudinal axis. The filter unit includes an upstream filter unit positioned relatively upstream in the filter longitudinal direction and a downstream filter unit positioned downstream of the upstream filter unit, and the first wrapping paper includes the upstream filter unit The tobacco rod including the tobacco cut and the upstream filter portion may be integrally wound, and the second wrapping paper may be wound around the outer periphery of the downstream filter portion. In this case, the upstream filter portion and the downstream filter portion may be rotatable relative to each other about the filter longitudinal axis at least within a predetermined range.
　また、本発明において、複数の光透過部は、互いに大きさが等しい長方形として形成されると共にフィルター周方向に並んで配置されており、且つ、各光透過部における長辺がフィルター長手方向に沿って配置されると共に該長辺の両端位置がフィルター長手方向において互いに揃っていてもよい。 Further, in the present invention, the plurality of light transmission parts are formed as rectangles having the same size and are arranged side by side in the filter circumferential direction, and the long side of each light transmission part is along the filter longitudinal direction. And both end positions of the long side may be aligned with each other in the filter longitudinal direction.
　また、本発明において、第１の包装紙と第２の包装紙との間には、香味を含む香味放出材が配設されていてもよい。この構成によれば、喫煙者による第２の包装紙の回動操作に伴い、例えば香味放出材が押圧されることで、香味放出材から香味が放出される。例えば、香味放出材が香料をカプセル内に封入する香料カプセルである場合、上記回動操作に伴って香料カプセルが圧搾（破砕）されることで、香料がカプセル外部に放出される。このように香味放出材から放出された香味は、例えば主流煙と共に喫煙者に吸引される。 In the present invention, a flavor release material containing flavor may be disposed between the first wrapping paper and the second wrapping paper. According to this structure, a flavor is discharge | released from a flavor discharge | release material by pressing a flavor release material, for example with a rotation operation of the 2nd wrapping paper by a smoker. For example, when the flavor release material is a fragrance capsule that encloses a fragrance in a capsule, the fragrance capsule is pressed (crushed) in association with the rotation operation, whereby the fragrance is released to the outside of the capsule. Thus, the flavor released from the flavor release material is sucked by the smoker together with the mainstream smoke, for example.
　上記構成によれば、アニメーションを生じさせるための第１の包装紙および第２の包装紙の相対変位操作に伴い、香味放出材から香味を放出させることができる。つまり、喫煙者に、香味放出材から香味を放出させることを意識させずに、主流煙に香味付けを行うことができる。また、第１の包装紙および第２の包装紙の相対変位操作により引き起こされるアニメーション機能によって喫煙者の興味を惹くことができるため、喫煙者によって第１の包装紙および第２の包装紙の相対変位操作が幾度となく繰り返し行われることになる。このように、複数回にわたって上記相対変位操作、つまり、香味放出材の押圧や摩擦が繰り返し行われることで、香味放出材からの香味の放出量を十分に確保することができる。もしくは、香味放出材から香味を放出させる所作により、同時にアニメーションを楽しむことが出来る。 According to the above configuration, the flavor can be released from the flavor release material in accordance with the relative displacement operation of the first wrapping paper and the second wrapping paper for causing animation. In other words, the mainstream smoke can be flavored without making the smoker aware of releasing the flavor from the flavor release material. Further, since the smoker can be interested by the animation function caused by the relative displacement operation of the first wrapping paper and the second wrapping paper, the relative relationship between the first wrapping paper and the second wrapping paper by the smoker. The displacement operation will be repeated many times. As described above, the relative displacement operation, that is, the pressing and friction of the flavor release material are repeatedly performed a plurality of times, so that a sufficient amount of flavor can be ensured from the flavor release material. Or you can enjoy the animation at the same time by the work of releasing the flavor from the flavor release material.
　また、香味放出材は、第１の包装紙および第２の包装紙のうち少なくとも何れか一方に接着されていてもよい。このように構成することで、香味放出材が移動して下絵の上に重なり合うことを回避し、第１の包装紙および第２の包装紙の相対変位操作時に光透過部を通じた下絵の視認性が悪化することを抑制できる。 Further, the flavor release material may be adhered to at least one of the first wrapping paper and the second wrapping paper. By comprising in this way, it avoids that a flavor discharge | release material moves and overlaps on a sketch, Visibility of a sketch through a light transmission part at the time of relative displacement operation of a 1st packaging paper and a 2nd packaging paper Can be suppressed.
　また、香味放出材は、第１の包装紙における下絵が配置される領域よりもフィルター長手方向下流側に対応する領域に配置されていてもよい。これによれば、第１の包装紙、或いは、第２の包装紙に接着されている香味放出材が剥離（離脱）しても、光透過部を通じた下絵の視認性が悪化することをより一層確実に抑制することができる。 Further, the flavor release material may be arranged in a region corresponding to the downstream side in the longitudinal direction of the filter from the region in which the sketch in the first wrapping paper is arranged. According to this, even if the flavor release material adhered to the first wrapping paper or the second wrapping paper is peeled (detached), the visibility of the sketch through the light transmitting portion is further deteriorated. It can suppress more reliably.
　ここで、香味放出材は、着色された液体の香料を封入したカプセルであってもよい。これによれば、光透過部を通じて喫煙者に視認される下絵の外観を変化させることができる。よって、スリットアニメーションの新たなデザイン変化を喫煙者に提供することができる。 Here, the flavor release material may be a capsule enclosing a colored liquid fragrance. According to this, the appearance of the sketch visually recognized by the smoker through the light transmission part can be changed. Therefore, a new design change of the slit animation can be provided to the smoker.
　また、本発明における喫煙物品用フィルターにおいて、第１の包装紙が通気性を有していてもよい。これによれば、香味放出材から放出された香味を、フィルター内部側に好適に導入することができ、当該香味を主流煙とともに喫煙者の口腔内に好適に導くことができる。 Further, in the filter for smoking articles in the present invention, the first wrapping paper may have air permeability. According to this, the flavor discharge | released from the flavor releasing material can be introduce | transduced suitably inside a filter, and the said flavor can be suitably guide | induced to a smoker's oral cavity with mainstream smoke.
　また、第１の包装紙のうち、香味放出材が配置される領域よりもフィルター長手方向下流側に対応する領域に、香味放出材から放出された香味をフィルター内側に導入するための導入孔が形成されていてもよい。これによれば、第１の包装紙に用いる材料が通気性を有していなくても、香味放出材から放出された香味を、主流煙とともに喫煙者の口腔内に好適に導くことができる。 In addition, an introduction hole for introducing the flavor released from the flavor release material into the inside of the filter in a region corresponding to the downstream side in the longitudinal direction of the filter from the region where the flavor release material is arranged in the first wrapping paper. It may be formed. According to this, even if the material used for the first wrapping paper does not have air permeability, the flavor released from the flavor release material can be suitably guided into the smoker's mouth along with the mainstream smoke.
　また、本発明は、上述までの何れかに記載の喫煙物品用フィルターを備える喫煙物品であってもよい。また、本発明に係る喫煙物品フィルターは、シガレット、葉巻、シガリロ等のような燃焼を伴う喫煙物品に加えて、タバコを加熱して吸引する喫煙物品やタバコを加熱することなく吸引する喫煙物品に適用してもよい。 Further, the present invention may be a smoking article provided with the filter for smoking articles described above. Moreover, the smoking article filter according to the present invention can be used for smoking articles that heat and suck cigarettes in addition to smoking articles with combustion such as cigarettes, cigars, cigarillos, and the like. You may apply.
　また、本発明における課題を解決するための手段は、可能な限り組み合わせて採用することができる。 Further, means for solving the problems in the present invention can be employed in combination as much as possible.
　本発明によれば、従来にはなかった外観品質を有する喫煙物品用フィルターを提供することができる。 According to the present invention, it is possible to provide a filter for a smoking article having an appearance quality that has not existed before.

＜実施形態１＞
　図１は、実施形態１に係るシガレット１の断面構造を示す図である。図２は、実施形態１に係るシガレット１の外観を示す図である。 <Embodiment 1>
FIG. 1 is a diagram illustrating a cross-sectional structure of a cigarette 1 according to the first embodiment. FIG. 2 is a diagram illustrating an appearance of the cigarette 1 according to the first embodiment.
　シガレット１は、タバコロッド２と、タバコロッド２の一端に接続されたシガレットフィルター（以下、単に「フィルター」という）３を備えている。タバコロッド２は、タバコ刻２１、および、このタバコ刻２１を巻き上げる巻紙２２を含み、ロッド形状を有している。図１および図２において、タバコロッド２の先端側の図示を省略している。 The cigarette 1 includes a tobacco rod 2 and a cigarette filter (hereinafter simply referred to as “filter”) 3 connected to one end of the tobacco rod 2. The tobacco rod 2 includes a tobacco stamp 21 and a wrapping paper 22 that winds up the tobacco stamp 21, and has a rod shape. In FIG. 1 and FIG. 2, illustration of the tip end side of the tobacco rod 2 is omitted.
　フィルター３は、所謂デュアルフィルター構造となっており、フィルター長手方向における上流側から第１フィルタープラグ４および第２フィルタープラグ５を備えている。第１フィルタープラグ４および第２フィルタープラグ５の種類は特定のものに限定されない。第１フィルタープラグ４および第２フィルタープラグ５は、共に、濾材（濾過材）を含み、円柱状に成形されている。第２フィルタープラグ５は、例えば、セルロースアセテートの繊維束の周囲を巻取紙で巻き取ったプレーンフィルターである。また、第１フィルタープラグ４は、例えば、プレーンフィルターに活性炭等の吸着剤を分散させて構成したチャコールフィルターである。本実施形態においては、第１フィルタープラグ４および第２フィルタープラグ５が、本発明に係る上流フィルター部および下流フィルター部に相当する。また、第１フィルタープラグ４および第２フィルタープラグ５を含んで本発明におけるフィルター部が構成されている。 The filter 3 has a so-called dual filter structure, and includes a first filter plug 4 and a second filter plug 5 from the upstream side in the filter longitudinal direction. The types of the first filter plug 4 and the second filter plug 5 are not limited to specific types. Both the first filter plug 4 and the second filter plug 5 include a filter medium (filter medium) and are formed in a cylindrical shape. The second filter plug 5 is, for example, a plain filter in which the periphery of a fiber bundle of cellulose acetate is wound with a wrapping paper. The first filter plug 4 is, for example, a charcoal filter configured by dispersing an adsorbent such as activated carbon in a plain filter. In the present embodiment, the first filter plug 4 and the second filter plug 5 correspond to the upstream filter portion and the downstream filter portion according to the present invention. Moreover, the filter part in this invention is comprised including the 1st filter plug 4 and the 2nd filter plug 5. FIG.
　タバコロッド２とフィルター３とは、チップペーパー６を介して一体に接続されている。チップペーパー６は、第１フィルタープラグ４の外周全体とタバコロッド２の基端部とを覆うように、これらの接続部に跨って第１フィルタープラグ４およびタバコロッド２を一体に巻き取る包装紙であり、以下では「第１の包装紙」と呼ぶ。第１の包装紙はタバコロッド２と第１フィルタープラグ４の両方と接着されている。一方、第２フィルタープラグ５の外周は、第２の包装紙７によって巻き取られている。第２の包装紙７は、第２フィルタープラグ５の巻取紙に接着されており、図示のように、第２フィルタープラグ５の上流端（前端）からタバコロッド２側に向けて延伸している。本実施形態において、第２の包装紙７は、第１の包装紙６の外周に覆い被さるように配置されており、その上流端部の位置は第１の包装紙６における上流端部の位置と略一致している。 The tobacco rod 2 and the filter 3 are integrally connected via a chip paper 6. The tip paper 6 is a wrapping paper that integrally winds up the first filter plug 4 and the tobacco rod 2 across these connecting portions so as to cover the entire outer periphery of the first filter plug 4 and the base end portion of the tobacco rod 2. Hereinafter, it is referred to as “first wrapping paper”. The first wrapping paper is bonded to both the tobacco rod 2 and the first filter plug 4. On the other hand, the outer periphery of the second filter plug 5 is wound up by the second wrapping paper 7. The second wrapping paper 7 is bonded to the web of the second filter plug 5 and extends from the upstream end (front end) of the second filter plug 5 toward the tobacco rod 2 as shown in the figure. In the present embodiment, the second wrapping paper 7 is disposed so as to cover the outer periphery of the first wrapping paper 6, and the upstream end position thereof is the upstream end position of the first wrapping paper 6. Is almost the same.
　なお、図示のように、第２の包装紙７の上流端部における内周面には帯状紙７ａが全周に亘って貼り付けられている。一方、第１の包装紙６には、その外周面に帯状紙６ａが全周に亘って貼り付けられている。第１の包装紙６の帯状紙６ａは、第２の包装紙７における帯状紙７ａの内側に隣接するように配置されている。ここで、第１の包装紙６は、タバコロッド２の外周と接着されているため、第２の包装紙７がフィルター３の後端側に引っ張られても、第１の包装紙６における帯状紙６ａの前端縁部と第２の包装紙７における帯状紙７ａの後端縁部とが係合することで、第２の包装紙７および第２フィルタープラグ５が、第１フィルタープラグ４およびタバコロッド２から不用意に分離することを抑制できる。また、帯状紙を張り付ける代わりに包装紙を折ることでも係合させることができる。 Note that, as shown in the figure, a belt-like paper 7 a is attached to the inner peripheral surface at the upstream end portion of the second wrapping paper 7 over the entire circumference. On the other hand, the first wrapping paper 6 has a belt-like paper 6a attached to the outer peripheral surface thereof over the entire circumference. The strip 6a of the first wrapping paper 6 is disposed so as to be adjacent to the inside of the strip 7a of the second wrapping paper 7. Here, since the first wrapping paper 6 is bonded to the outer periphery of the tobacco rod 2, even if the second wrapping paper 7 is pulled to the rear end side of the filter 3, the first wrapping paper 6 has a strip shape. By engaging the front edge of the paper 6a with the rear edge of the belt 7a in the second wrapping paper 7, the second wrapping paper 7 and the second filter plug 5 are connected to the first filter plug 4 and Inadvertent separation from the tobacco rod 2 can be suppressed. Moreover, it can also be engaged by folding a wrapping paper instead of sticking a strip | belt-shaped paper.
　図２に示すように、第２の包装紙７には、複数の長方形の開口部であるスリット窓８が並んで配置されている。各スリット窓８は、互いに大きさが等しい長方形として形成されており、第２の包装紙７をスリット状に切り欠くことで形成されている。また、各スリット窓８の長辺は、フィルター長手方向に沿って配置されており、フィルター３の周方向に一定間隔で並べられている。また、各スリット窓８は、図２に示すように、長辺の両端位置がフィルター長手方向において互いに揃っている。つまり、各スリット窓８の長辺における前端および後端の夫々が、スリット窓８同士で一致している。また、フィルター周方向において、隣接するスリット窓８同士の間隔は、スリット窓８の短辺の長さに等しくなっている。また、第２の包装紙７は、スリット窓８を除いて、不透明な材料で構成されている。本実施形態においては、スリット窓８が本発明に係る光透過部に相当する。 As shown in FIG. 2, the second wrapping paper 7 is provided with slit windows 8 that are a plurality of rectangular openings. Each slit window 8 is formed as a rectangle having the same size, and is formed by cutting out the second wrapping paper 7 into a slit shape. The long sides of the slit windows 8 are arranged along the filter longitudinal direction, and are arranged at regular intervals in the circumferential direction of the filter 3. Moreover, as shown in FIG. 2, each slit window 8 has both ends of the long side aligned with each other in the filter longitudinal direction. That is, the front end and the rear end on the long sides of the slit windows 8 coincide with each other in the slit windows 8. In the filter circumferential direction, the interval between the adjacent slit windows 8 is equal to the length of the short side of the slit window 8. The second wrapping paper 7 is made of an opaque material except for the slit window 8. In the present embodiment, the slit window 8 corresponds to the light transmission portion according to the present invention.
　一方、第１の包装紙６の外周面には、図３の左下に示すような複数の画像が合成された複合画像で構成された下絵９が配置されている。下絵９は、複数の画像が合成された複合画像で構成されている。例えば、図３に示す例では、星形をモチーフとした第１の画像と、円形をモチーフとした第２の画像とを、組み合わせて複合画像が形成されている。複合画像に含まれる各画像は、所定の間隔で間引いて、「残像」と「欠け」が繰り返されている。図３に示す例では、第１の画像および第２の画像の夫々を等間隔“Ｘ”で間引いている。そして、第１の画像と第２の画像とを複合させる際に、第１の画像の「欠け」の部分に、第２の中間画像の「残像」部分が一致するようにして、複合画像が作成されている。本実施形態に係るフィルター３においては、図３に示す複合画像で構成された下絵９が、第１の包装紙６の外周面に印刷されている。なお、第１の包装紙６の外周面とは、第１の包装紙６の外周に覆い被せられている第２の包装紙７の内周面と向き合う面を指す。 On the other hand, on the outer peripheral surface of the first wrapping paper 6, a sketch 9 composed of a composite image composed of a plurality of images as shown in the lower left of FIG. 3 is arranged. The sketch 9 is composed of a composite image obtained by combining a plurality of images. For example, in the example shown in FIG. 3, a composite image is formed by combining a first image with a star shape as a motif and a second image with a circle as a motif. Each image included in the composite image is thinned at a predetermined interval, and “afterimage” and “missing” are repeated. In the example shown in FIG. 3, each of the first image and the second image is thinned out at equal intervals “X”. Then, when combining the first image and the second image, the “afterimage” portion of the second intermediate image matches the “missing” portion of the first image so that the composite image is Has been created. In the filter 3 according to the present embodiment, a sketch 9 composed of the composite image shown in FIG. 3 is printed on the outer peripheral surface of the first wrapping paper 6. The outer peripheral surface of the first wrapping paper 6 refers to a surface that faces the inner peripheral surface of the second wrapping paper 7 that is covered by the outer periphery of the first wrapping paper 6.
　一方、複数のスリット窓８が設けられた第２の包装紙７においても、フィルター３の周方向において隣接するスリット窓８同士の間隔、およびスリット窓８の短辺寸法は、共に“Ｘ”で等しくなっている。図３の左上図は、第２の包装紙７を展開した状態を模式的に示した図であり、スリット窓８が設けられている部分を白抜きにして示し、その周囲を囲む不透明部分を塗りつぶしている。本実施形態に係るフィルター３は、第１の包装紙６における下絵９と、第２の包装紙７におけるスリット窓８との、フィルター長手方向での位置関係が対応するように構成されている。 On the other hand, in the second wrapping paper 7 provided with a plurality of slit windows 8, the interval between adjacent slit windows 8 in the circumferential direction of the filter 3 and the short side dimension of the slit window 8 are both “X”. Are equal. The upper left figure of FIG. 3 is the figure which showed typically the state which expand | deployed the 2nd wrapping paper 7, and shows the part in which the slit window 8 is provided in white, and the opaque part surrounding the circumference | surroundings Filled. The filter 3 according to this embodiment is configured such that the positional relationship in the filter longitudinal direction between the sketch 9 in the first wrapping paper 6 and the slit window 8 in the second wrapping paper 7 corresponds.
　フィルター３において、第１の包装紙６に巻き取られた第１フィルタープラグ４は、タバコロッド２と一体に接続される一方、第２の包装紙７は、第２フィルター５と共にフィルター３の長手軸を中心として回動自在に構成されている。従って、フィルター３における第１の包装紙６と第２の包装紙７とは、フィルター３の長手軸を中心として相対回動（所定方向への相対変位）が可能となっている。更に、本実施形態におけるフィルター３においては、第１の包装紙６における下絵９の配置領域と、第２の包装紙７におけるスリット窓８の配置領域とが、フィルター３の長手方向において互いに対応付けられているため、喫煙者が、第１の包装紙６に対して第２の包装紙７を回動させた際、第２の包装紙７における複数のスリット窓８を通じて、第１の包装紙６の下絵９に係る複合画像を喫煙者に視認させることができる。 In the filter 3, the first filter plug 4 wound around the first wrapping paper 6 is integrally connected to the tobacco rod 2, while the second wrapping paper 7 together with the second filter 5 is the longitudinal length of the filter 3. It is configured to be rotatable about an axis. Accordingly, the first wrapping paper 6 and the second wrapping paper 7 in the filter 3 can be relatively rotated (relative displacement in a predetermined direction) around the longitudinal axis of the filter 3. Furthermore, in the filter 3 according to the present embodiment, the arrangement area of the sketch 9 in the first wrapping paper 6 and the arrangement area of the slit window 8 in the second wrapping paper 7 are associated with each other in the longitudinal direction of the filter 3. Therefore, when the smoker rotates the second wrapping paper 7 with respect to the first wrapping paper 6, the first wrapping paper passes through the plurality of slit windows 8 in the second wrapping paper 7. The smoker can visually recognize the composite image related to the sketch 9.
　ここで、第１の包装紙６および第２の包装紙７をフィルター３の長手軸を中心に回動させると、図３に示すように、第１の包装紙６に印刷された下絵９と第２の包装紙７とが相対スライドするところ、第１の画像の「残像」が第２の包装紙７のスリット窓８と上下に重なっているときは、第１の画像が表す模様、すなわち星形模様が視認される（Ａ）。一方、第２の画像の「残像」が第２の包装紙７のスリット窓８と上下に重なっているときは、第２の画像が表す模様、すなわち円形模様が視認される（Ｂ）。 Here, when the first wrapping paper 6 and the second wrapping paper 7 are rotated around the longitudinal axis of the filter 3, as shown in FIG. 3, the sketch 9 printed on the first wrapping paper 6 and When the second wrapping paper 7 is relatively slid, when the “afterimage” of the first image overlaps with the slit window 8 of the second wrapping paper 7, the pattern represented by the first image, that is, A star pattern is visible (A). On the other hand, when the “afterimage” of the second image overlaps with the slit window 8 of the second wrapping paper 7, the pattern represented by the second image, that is, the circular pattern is visually recognized (B).
　以上述べた複合画像によって構成される下絵９と、複数のスリット窓８を備えた第２の包装紙７との相対的なスライド動作を適度な速度で行うと、人間の目には、あたかも星形模様と円形模様が動的に変化しているかのように視認されるため、動画を生じさせる視覚的効果が得られる。つまり、本実施形態においては、従来では達成できなかった外観品質を有する喫煙物品用フィルターを提供することができる。これにより、フィルター３およびこれを備えたシガレット１の商品価値を高めることができる。 If the relative sliding movement of the sketch 9 composed of the composite image described above and the second wrapping paper 7 provided with the plurality of slit windows 8 is performed at an appropriate speed, the human eye will feel as if it is a star. Since the shape pattern and the circular pattern are visually recognized as if they are dynamically changing, a visual effect that produces a moving image can be obtained. That is, in this embodiment, the filter for smoking articles which has the external appearance quality which was not able to be achieved conventionally can be provided. Thereby, the commercial value of filter 3 and cigarette 1 provided with this can be raised.
　なお、スリットアニメーションに関する技術自体は公知のものであり、ここでの詳しい説明は省略するが、複合画像に組み込まれる画像の数を３以上にすることも可能である。 Note that the technology relating to the slit animation itself is publicly known, and detailed description thereof is omitted here, but the number of images incorporated in the composite image can be increased to 3 or more.
　また、図１および図２に示すフィルター３では、第２の包装紙７に形成する複数の光透過部の一例として長方形の開口部であるスリット窓８を設けているが、透明材料を用いて光透過部を形成してもよい。ここでいう「透明」との用語は、完全にまたは部分的に透けて見えるあらゆる材料を意味するものとする。これは、例えば、色には関係なく、透明、薄い色のついた、又は「半透明」な材料も「透明」とみなす。「透明」な材料としては、例えば、ポリプロピレン、ポリビニルクロライド（ＰＶＣ）、セルロースアセテートフィルム、ポリエチレンテレフタレート（ＰＥＴ）、ポリエチレンオキシド（ＰＥＯＸ）、ポリエチレン、セロハン、ポリ乳酸（ＰＬＡ）などが挙げられるが、これらに限定されない。 Moreover, in the filter 3 shown in FIG. 1 and FIG. 2, although the slit window 8 which is a rectangular opening part is provided as an example of the some light transmissive part formed in the 2nd wrapping paper 7, it uses a transparent material. A light transmission part may be formed. As used herein, the term “transparent” shall mean any material that is completely or partially transparent. For example, a transparent, lightly colored or “translucent” material is considered “transparent”, regardless of color. Examples of the “transparent” material include polypropylene, polyvinyl chloride (PVC), cellulose acetate film, polyethylene terephthalate (PET), polyethylene oxide (PEOX), polyethylene, cellophane, polylactic acid (PLA), and the like. It is not limited to.
　なお、本実施形態のフィルター３において、第２の包装紙７に形成されるスリット窓８の数は複数であれば特段限定されないが、３個以上であると好ましい。また、５個以上２０個以下であると、高度（複雑）なスリットアニメーションの表現を実現可能とする観点から、特に好ましい。 In the filter 3 of the present embodiment, the number of slit windows 8 formed on the second wrapping paper 7 is not particularly limited as long as it is plural, but is preferably three or more. Further, it is particularly preferable that the number is 5 or more and 20 or less from the viewpoint of realizing high-level (complex) slit animation expression.
　なお、本実施形態のフィルター３においては、下絵９が配される第１の包装紙６と、この第１の包装紙６の外周を覆う第２の包装紙７とを３６０°相対回転自在に構成しているが、第１の包装紙６および第２の包装紙７における所定方向への相当変位が可能であればよい。また、上述したフィルター３においては、第１フィルタープラグ４および第２フィルタープラグ５をフィルター長手方向に直列に配置したが、これには限定されず、フィルター３内に単一のフィルタープラグ（セグメント）を配置する構成であってもよい。 In the filter 3 of the present embodiment, the first wrapping paper 6 on which the sketch 9 is arranged and the second wrapping paper 7 that covers the outer periphery of the first wrapping paper 6 are relatively rotatable by 360 °. Although it is configured, it is only necessary that the first wrapping paper 6 and the second wrapping paper 7 can be displaced in a predetermined direction. In the filter 3 described above, the first filter plug 4 and the second filter plug 5 are arranged in series in the filter longitudinal direction. However, the present invention is not limited to this, and a single filter plug (segment) is provided in the filter 3. The structure which arrange | positions may be sufficient.
　図４は、第１変形例に係るフィルター３Ａの概略構造を示す図である。図１乃至３で説明したフィルター３と共通する部材には、共通の参照符号が付されている。図４に示すフィルター３Ａにおいて、符号４０は、フィルター３Ａ内に配置されたフィルタープラグを示す。フィルター３Ａは、単一のフィルタープラグ４０を有している。フィルタープラグ４０は、例えば、上述の第１フィルタープラグ４と同様な円柱状のプレーンフィルターである。フィルタープラグ４０の長手方向における中途部には、フィルタープラグ４０の径方向に向かって伸びる環状の切欠き溝４１が設けられている。切欠き溝４１の最深部は、フィルタープラグ４０の軸中心までは至っておらず、フィルタープラグ４０の横断面における切欠き溝４１の内側には断面コア部４２が残されている。また、切欠き溝４１は、フィルタープラグ４０の外周面からの深さが大きくなるに従い、その溝幅が狭められている。 FIG. 4 is a diagram showing a schematic structure of the filter 3A according to the first modification. Members common to the filter 3 described in FIGS. 1 to 3 are denoted by common reference numerals. In the filter 3A shown in FIG. 4, reference numeral 40 denotes a filter plug arranged in the filter 3A. The filter 3A has a single filter plug 40. The filter plug 40 is, for example, a cylindrical plain filter similar to the first filter plug 4 described above. An annular notch groove 41 extending in the radial direction of the filter plug 40 is provided in a midway portion in the longitudinal direction of the filter plug 40. The deepest portion of the notch groove 41 does not reach the axial center of the filter plug 40, and a cross-sectional core portion 42 remains inside the notch groove 41 in the cross section of the filter plug 40. Further, the groove width of the cutout groove 41 is narrowed as the depth from the outer peripheral surface of the filter plug 40 increases.
　ここで、フィルタープラグ４０の長手方向において、切欠き溝４１よりも上流側を上流フィルター部４０ａと呼び、切欠き溝４１よりも下流側を下流フィルター部４０ｂと呼ぶ。ここで、上流フィルター部４０ａおよび下流フィルター部４０ｂの境界には環状の切欠き溝４１が形成されているため、フィルタープラグ４０の長手軸を中心に、上流フィルター部４０ａおよび下流フィルター部４０ｂを所定の範囲（所定の角度範囲）内で相対的に回動させることができる。 Here, in the longitudinal direction of the filter plug 40, the upstream side of the notch groove 41 is referred to as an upstream filter portion 40a, and the downstream side of the notch groove 41 is referred to as a downstream filter portion 40b. Here, since an annular notch groove 41 is formed at the boundary between the upstream filter portion 40a and the downstream filter portion 40b, the upstream filter portion 40a and the downstream filter portion 40b are set to a predetermined centering on the longitudinal axis of the filter plug 40. Within a range (predetermined angle range).
　また、図４に示すように、上流フィルター部４０ａの外周には、上述した第１の包装紙６が巻かれており、この第１の包装紙６を介してフィルタープラグ４０とタバコロッド２とが一体に接続されている。第１の包装紙６は、上流フィルター部４０ａの外周部のみに接着されており、切欠き溝４１および下流フィルター部４０ｂの外周は覆っていない。一方、下流フィルター部４０ｂの外周部には、第２の包装紙７が接着されている。この第２の包装紙７は、下流フィルター部４０ｂの上流端（前端）からタバコロッド２側に向けて延伸している。そして、第２の包装紙７は、第１の包装紙６の外周に覆うように配置されている。 Further, as shown in FIG. 4, the first wrapping paper 6 described above is wound around the outer periphery of the upstream filter portion 40 a, and the filter plug 40, the tobacco rod 2, and the like are interposed via the first wrapping paper 6. Are connected together. The first wrapping paper 6 is bonded only to the outer peripheral portion of the upstream filter portion 40a, and does not cover the outer periphery of the notch groove 41 and the downstream filter portion 40b. On the other hand, the 2nd wrapping paper 7 is adhere | attached on the outer peripheral part of the downstream filter part 40b. The second wrapping paper 7 extends from the upstream end (front end) of the downstream filter portion 40b toward the tobacco rod 2 side. The second wrapping paper 7 is disposed so as to cover the outer periphery of the first wrapping paper 6.
　上記構成のフィルター３Ａにおいても、上述したフィルター３と同様に、第１の包装紙６の外周面に複合画像で構成された下絵９（図３を参照）が配置され、第２の包装紙７には複数のスリット窓８が配置されている。下絵９およびスリット窓８の配置形態等については、上述したフィルター３と同様であり、喫煙者が、第１の包装紙６に対して第２の包装紙７を回動させた際、第２の包装紙７における複数のスリット窓８を通じて、第１の包装紙６の下絵９に係る複合画像を喫煙者に視認させることができる。例えば、喫煙者が第２の包装紙７を把持して下流フィルター部４０ｂを捻ると、切欠き溝４１を境に下流フィルター部４０ｂおよび上流フィルター部４０ａが所定の角度範囲内で相対回動する。そうすることで、下絵９とスリット窓８とが相対的にスライドすることで、下絵９における第１の画像の「残像」と第２の画像の「残像」とが交互にスリット窓８から視認されることにより、星形模様と円形模様が動的に変化しているかのような視覚的効果が得られる。これにより、フィルター３と同様、喫煙物品用フィルターに新たな外観品質を提供し、商品価値を高めることができる。 Also in the filter 3A having the above-described configuration, the sketch 9 (see FIG. 3) configured with a composite image is arranged on the outer peripheral surface of the first wrapping paper 6 in the same manner as the filter 3 described above, and the second wrapping paper 7 A plurality of slit windows 8 are arranged in the. The layout of the sketch 9 and the slit window 8 is the same as that of the filter 3 described above, and when the smoker rotates the second wrapping paper 7 with respect to the first wrapping paper 6, the second Through the plurality of slit windows 8 in the wrapping paper 7, the smoker can visually recognize the composite image related to the sketch 9 of the first wrapping paper 6. For example, when the smoker grips the second wrapping paper 7 and twists the downstream filter portion 40b, the downstream filter portion 40b and the upstream filter portion 40a relatively rotate within a predetermined angle range with the notch groove 41 as a boundary. . By doing so, the background 9 and the slit window 8 slide relative to each other, so that the “afterimage” of the first image and the “afterimage” of the second image in the background 9 are alternately viewed from the slit window 8. By doing so, a visual effect is obtained as if the star pattern and the circular pattern are dynamically changing. Thereby, like the filter 3, a new external appearance quality can be provided to the filter for smoking articles, and commercial value can be raised.
　なお、上述までのフィルター３，３Ａにおいて、第１の包装紙６と第２の包装紙７を相対的に変位させる方向は、上記実施形態の例に限定されず、種々の態様を採用することができる。例えば、フィルター３，３Ａの長手軸方向に沿って第１の包装紙６と第２の包装紙７とを相対スライド自在に構成してもよい。この場合、第２の包装紙７におけるスリット窓８は、長方形の長辺がフィルター長手軸と直交する方向に沿って配置するとよい。これにより、第１の包装紙６および第２の包装紙７を相対スライドさせた際に、喫煙者にスリットアニメーションを好適に視認させることができる。また、上記フィルター３，３Ａにおいて、第１の包装紙６の外周面における下絵９の配置位置は、第１フィルタープラグ４、上流フィルター部４０ａに限られず、第１の包装紙６がタバコロッド２の端部領域を巻き取る部分に下絵９を配置してもよい。これにより、下絵９の配置可能範囲を拡大することができる。 In the filters 3 and 3A described above, the direction in which the first wrapping paper 6 and the second wrapping paper 7 are relatively displaced is not limited to the example in the above embodiment, and various aspects are adopted. Can do. For example, the first wrapping paper 6 and the second wrapping paper 7 may be configured to be relatively slidable along the longitudinal axis direction of the filters 3 and 3A. In this case, the slit window 8 in the second wrapping paper 7 is preferably arranged along the direction in which the long side of the rectangle is orthogonal to the filter longitudinal axis. Thereby, when the 1st wrapping paper 6 and the 2nd wrapping paper 7 are slid relatively, a smoker can be made to visually recognize a slit animation suitably. In the filters 3 and 3A, the arrangement position of the sketch 9 on the outer peripheral surface of the first wrapping paper 6 is not limited to the first filter plug 4 and the upstream filter portion 40a, and the first wrapping paper 6 is the tobacco rod 2. The sketch 9 may be arranged in a portion where the end region is wound up. Thereby, the arrangement | positioning possible range of the sketch 9 can be expanded.
＜実施形態２＞
　次に、実施形態２に係るフィルター３Ｂを説明する。フィルター３Ｂにおける基本構成は、実施形態１に係るフィルター３と共通するため、ここでは、フィルター３と相違する点を中心に説明する。図５は、実施形態２に係るフィルター３Ｂの概略構造を示す図である。フィルター３Ｂは、第１の包装紙６と第２の包装紙７との間に、香味を含む香味放出材としての香料カプセル１０が配設されていることを特徴としている。香料カプセル１０の直径は、特段限定されないが、本実施形態では第１の包装紙６および第２の包装紙７の間に挟みこむように配設するため、直径が０．５ｍｍ以下であると好ましい。また、香料カプセル１０を配設する数は特定の数に限定されないものの、本実施形態では比較的小さな香料カプセル１０が多数設けられている。 <Embodiment 2>
Next, the filter 3B according to the second embodiment will be described. Since the basic configuration of the filter 3B is the same as that of the filter 3 according to the first embodiment, the description here will focus on differences from the filter 3. FIG. 5 is a diagram illustrating a schematic structure of a filter 3B according to the second embodiment. The filter 3B is characterized in that a fragrance capsule 10 as a flavor release material including a flavor is disposed between the first wrapping paper 6 and the second wrapping paper 7. Although the diameter of the fragrance capsule 10 is not particularly limited, in the present embodiment, the fragrance capsule 10 is disposed so as to be sandwiched between the first wrapping paper 6 and the second wrapping paper 7, and thus the diameter is preferably 0.5 mm or less. . Moreover, although the number which arrange | positions the fragrance | flavor capsule 10 is not limited to a specific number, in this embodiment, many comparatively small fragrance | flavor capsules 10 are provided.
　香料カプセル１０には、液体の香料が、破砕可能なカプセルに封入されている。このカプセルは、例えばゼラチンで形成されていてもよい。ここで、香料カプセル１０は、第１の包装紙６の外周面に接着されている。但し、香料カプセル１０は、第２の包装紙７の内周面に接着されていてもよいし、第１の包装紙６における外周面および第２の包装紙７における内周面の双方に接着されていてもよい。つまり、第１の包装紙６および第２の包装紙７の少なくとも何れか一方に香料カプセル１０が接着されていればよい。また、本実施形態における香料カプセル１０においては、カプセル内に封入された液体の香料が顔料等によって着色されている。また、本実施形態のフィルター３Ｂにおいて、第１の包装紙６は通気性を有している。更に、第１の包装紙６および第２の包装紙７の間に配置される香料カプセル１０は、第１の包装紙６のうち、下絵９が配置される下絵配置領域６ｂよりもフィルター長手方向下流側に対応する領域に配置されている。 In the fragrance capsule 10, a liquid fragrance is enclosed in a capsule that can be crushed. The capsule may be made of gelatin, for example. Here, the fragrance capsule 10 is bonded to the outer peripheral surface of the first wrapping paper 6. However, the fragrance capsule 10 may be bonded to the inner peripheral surface of the second wrapping paper 7 or bonded to both the outer peripheral surface of the first wrapping paper 6 and the inner peripheral surface of the second wrapping paper 7. May be. That is, the fragrance capsule 10 only needs to be adhered to at least one of the first wrapping paper 6 and the second wrapping paper 7. Moreover, in the fragrance | flavor capsule 10 in this embodiment, the liquid fragrance | flavor enclosed in the capsule is colored with the pigment etc. Moreover, in the filter 3B of this embodiment, the 1st wrapping paper 6 has air permeability. Further, the fragrance capsule 10 arranged between the first wrapping paper 6 and the second wrapping paper 7 is longer in the filter longitudinal direction than the underlay arrangement area 6b in which the undercoat 9 is arranged in the first wrapping paper 6. It is arranged in a region corresponding to the downstream side.
　以上のように構成されるフィルター３Ｂにおいては、喫煙者によって、第１の包装紙６に対する第２の包装紙７の回動操作が行われることで、実施形態１におけるフィルター３と同様に、第１の包装紙６に配置されている複合画像で構成された下絵９と、第２の包装紙７における複数のスリット窓８とが、相対的にスライドすることで、スリットアニメーションを生じさせる視覚的効果が得られる。更に、本実施形態に係るフィルター３Ｂよれば、第１の包装紙６および第２の包装紙７の間に、香味放出材としての香料カプセル１０が配設されているため、上述した喫煙者による第２の包装紙７の回動操作時に香料カプセル１０が押圧されたり摩擦されることで、圧搾（破砕）される。これにより、香料カプセル１０のカプセルに封入されている香料がカプセル外に放出される。 In the filter 3B configured as described above, the second operation of the second wrapping paper 7 with respect to the first wrapping paper 6 is performed by the smoker. Visually causing a slit animation by the relative slide of a sketch 9 composed of a composite image arranged on one wrapping paper 6 and a plurality of slit windows 8 in the second wrapping paper 7 An effect is obtained. Furthermore, according to the filter 3B according to the present embodiment, since the fragrance capsule 10 as the flavor release material is disposed between the first wrapping paper 6 and the second wrapping paper 7, the smoker described above. When the second wrapping paper 7 is rotated, the fragrance capsule 10 is pressed or rubbed to be squeezed (crushed). Thereby, the fragrance | flavor enclosed with the capsule of the fragrance | flavor capsule 10 is discharge | released out of a capsule.
　ところで、フィルター３Ｂにおける第１の包装紙および第１フィルタープラグ４の巻取紙は通気性を有している。このため、香料カプセル１０から放出された香料に含まれる香味は、第１フィルタープラグ４の内部に導入され、主流煙とともに喫煙者の口腔内に導かれる。フィルター３Ｂによれば、スリットアニメーションを生じさせるための第１の包装紙６および第２の包装紙７の相対回動操作に伴い、香料カプセル１０から香味（香料）を放出させることができる。つまり、喫煙者に、香料カプセル１０から香味（香料）を放出させることを意識させずに、主流煙に香味付けを行うことができる。また、スリットアニメーション機能が喫煙者の興味を惹くことで、喫煙者によって第１の包装紙６および第２の包装紙７の相対回動操作が繰り返し行われることになる。このように、複数回にわたって第２の包装紙７の回動操作、言い換えると香料カプセル１０の圧砕操作が繰り返し行われることで、より多くの香料カプセル１０を圧砕することができ、香味の放出量、放出度合いを十分に増やすことができる。以上のように、本実施形態のフィルター３Ｂによれば、アニメーションを起こさせるための喫煙者による操作を利用して主流煙への香味付けを行うことができる。 Incidentally, the first wrapping paper in the filter 3B and the winding paper of the first filter plug 4 have air permeability. For this reason, the flavor contained in the fragrance | flavor discharged | emitted from the fragrance | flavor capsule 10 is introduce | transduced into the inside of the 1st filter plug 4, and is guide | induced to a smoker's oral cavity with mainstream smoke. According to the filter 3B, the flavor (fragrance) can be released from the fragrance capsule 10 in accordance with the relative rotation operation of the first wrapping paper 6 and the second wrapping paper 7 for generating the slit animation. That is, the mainstream smoke can be flavored without making the smoker aware of releasing the flavor (fragrance) from the flavor capsule 10. Further, the slit animation function attracts the smoker's interest, so that the relative rotation operation of the first wrapping paper 6 and the second wrapping paper 7 is repeatedly performed by the smoker. In this way, by rotating the second wrapping paper 7 multiple times, in other words, by repeatedly performing the crushing operation of the fragrance capsule 10, more fragrance capsules 10 can be crushed, and the amount of flavor released is reduced. The release degree can be increased sufficiently. As described above, according to the filter 3B of the present embodiment, it is possible to add flavor to mainstream smoke by using an operation by a smoker to cause an animation.
　また、フィルター３Ｂによれば、第１の包装紙６および第２の包装紙７の少なくとも何れか一方に香料カプセル１０（香味放出材）が接着されているため、香料カプセル１０が下絵９の上に重なってしまうことを抑制できる。従って、スリット窓８を通じた下絵９の視認性が悪化することを抑制できる。更に、フィルター３Ｂによれば、喫煙者による第１の包装紙６および第２の包装紙７の相対回動操作に伴って、第１の包装紙６に接着されている香料カプセル１０がたとえ剥離（離脱）した場合においても、第１の包装紙６のうち、下絵９が配置される下絵配置領域６ｂよりも下流側の領域に香料カプセル１０が配置されているため、スリット窓８を通じた下絵９の視認性が悪化しにくい。喫煙者がシガレット１を吸引する吸引力が第１の包装紙６から剥離した香料カプセル１０に作用しても、下絵９の下流側に香料カプセル１０を予め配置しておくことで、剥離した香料カプセル１０が下絵９を覆うことを回避できる。 Further, according to the filter 3B, since the fragrance capsule 10 (flavor release material) is adhered to at least one of the first wrapping paper 6 and the second wrapping paper 7, the fragrance capsule 10 is placed on the sketch 9. Can be prevented from overlapping. Therefore, it is possible to suppress deterioration of the visibility of the background 9 through the slit window 8. Further, according to the filter 3B, the perfume capsule 10 adhered to the first wrapping paper 6 is peeled off with the relative rotation operation of the first wrapping paper 6 and the second wrapping paper 7 by the smoker. Even in the case of (withdrawal), since the fragrance capsule 10 is arranged in the downstream region of the first wrapping paper 6 from the sketch placement region 6b in which the sketch 9 is placed, the sketch through the slit window 8 is used. The visibility of 9 is difficult to deteriorate. Even if the suction force of the smoker sucking the cigarette 1 acts on the fragrance capsule 10 peeled from the first wrapping paper 6, the fragrance peeled off by arranging the fragrance capsule 10 in advance on the downstream side of the sketch 9. It is possible to avoid the capsule 10 covering the background 9.
　また、上記のように、香料カプセル１０は、カプセル内に封入された液体の香料が着色されているため、スリット窓８を通じて喫煙者に視認される下絵９の外観を変化させることができる。よって、スリットアニメーションの新たなデザイン変化を喫煙者に提供することができる。 Further, as described above, since the fragrance capsule 10 is colored with the liquid fragrance enclosed in the capsule, the appearance of the sketch 9 that can be seen by the smoker through the slit window 8 can be changed. Therefore, a new design change of the slit animation can be provided to the smoker.
　次に、本実施形態における変形例について説明する。図６は、第２変形例に係るフィルター３Ｃの概略構造を示す図である。図６に示すフィルター３Ｃの基本構造は、図５で説明したフィルター３Ｂと同様であり、ここでは、フィルター３Ｂとの相違点を中心に説明する。フィルター３Ｃにおいても、第１の包装紙６と第２の包装紙７との間に、香味放出材としての香料カプセル１０が配設されている。一方、フィルター３Ｂにおいては第１の包装紙６が通気性を有しているのに対して、本変形例に係るフィルター３Ｃでは、第１の包装紙６が通気性を有しておらず、その代わりに外気をフィルター内側に導入するための導入孔６ｃが形成されている。また、導入孔６ｃは、第１の包装紙６のうち、香味放出材としての香料カプセル１０が配置される領域よりもフィルター長手方向下流側に対応する領域に設けられている。導入孔６ｃの数は特定の数に限定されないが、図６の構成例では、複数の導入孔６ｃがフィルター周方向に沿って環状に配置されている。 Next, a modified example in this embodiment will be described. FIG. 6 is a diagram illustrating a schematic structure of a filter 3C according to the second modification. The basic structure of the filter 3C shown in FIG. 6 is the same as that of the filter 3B described in FIG. 5, and here, the difference from the filter 3B will be mainly described. Also in the filter 3 </ b> C, a flavor capsule 10 as a flavor release material is disposed between the first wrapping paper 6 and the second wrapping paper 7. On the other hand, in the filter 3B, the first wrapping paper 6 has air permeability, whereas in the filter 3C according to this modification, the first wrapping paper 6 does not have air permeability. Instead, an introduction hole 6c for introducing outside air into the filter is formed. Moreover, the introduction hole 6c is provided in the area | region corresponding to the filter longitudinal direction downstream side of the 1st wrapping paper 6 rather than the area | region where the fragrance | flavor capsule 10 as a flavor releasing material is arrange | positioned. Although the number of introduction holes 6c is not limited to a specific number, in the configuration example of FIG. 6, a plurality of introduction holes 6c are annularly arranged along the filter circumferential direction.
　これによれば、第１の包装紙６に通気性を有しない材料を用いる場合においても、導入孔６ｃを通じて、香料カプセル１０から放出された香料を第１フィルタープラグ４の内部に導入し、当該香料を主流煙とともに喫煙者に吸引させることができる。なお、本変形例において、第１の包装紙６に通気性を有する材料を適用することは何ら妨げられない。つまり、通気性を有する材料を用いた第１の包装紙６のうち、香料カプセル１０が配置される領域よりも下流側に導入孔６ｃを形成してもよい。 According to this, even when a non-breathable material is used for the first wrapping paper 6, the fragrance released from the fragrance capsule 10 is introduced into the first filter plug 4 through the introduction hole 6c. Perfumes can be inhaled by smokers along with mainstream smoke. In addition, in this modification, applying the material which has air permeability to the 1st packaging paper 6 is not prevented at all. That is, the introduction hole 6c may be formed on the downstream side of the region where the fragrance capsule 10 is arranged in the first wrapping paper 6 using a material having air permeability.
　なお、上記実施形態２および第２変形例においては、第１の包装紙６および第２の包装紙７の間に、香味放出材として香料カプセル１０を配設したが、香料カプセル１０は香味放出材の一例である。例えば、香味放出材は、カプセル化せずに、粉状又は液体状の香味放出材を第１の包装紙６および第２の包装紙７の間に配置し、第１の包装紙６および第２の包装紙７が相対回動する際の摩擦によって香味が放出されるように構成されていてもよい。 In the second embodiment and the second modified example, the fragrance capsule 10 is disposed as the flavor release material between the first wrapping paper 6 and the second wrapping paper 7, but the fragrance capsule 10 is released from the flavor. It is an example of a material. For example, the flavor release material is not encapsulated, and a powdery or liquid flavor release material is disposed between the first wrapping paper 6 and the second wrapping paper 7, and the first wrapping paper 6 and the first wrapping paper 6 You may be comprised so that flavor may be discharge | released by the friction at the time of the 2 wrapping paper 7 rotating relatively.
　以上、本発明の好適な実施形態を説明したが、本発明に係る喫煙物品用フィルターは、可能な限り各実施形態および変形例を組み合わせて実施することができる。また、上述した実施形態および変形例に係る喫煙物品用フィルターは、種々の変更、改良、組み合わせ等が可能なことは当業者にとって自明である。例えば、上記の実施形態では、喫煙物品用フィルターとしてシガレットフィルターを例示的に説明したが、シガレットの他にも、葉巻、シガリロ用のフィルターに適用してもよい。また、シガレット、葉巻、シガリロ等のような燃焼を伴う喫煙物品に加えて、タバコを加熱して吸引する喫煙物品やタバコを加熱することなく吸引する喫煙物品に用いるフィルターに適用してもよい。 The preferred embodiments of the present invention have been described above, but the filter for smoking articles according to the present invention can be implemented in combination with each embodiment and modification as much as possible. In addition, it is obvious to those skilled in the art that the filter for smoking articles according to the above-described embodiments and modifications can be variously changed, improved, combined, and the like. For example, in the above embodiment, the cigarette filter has been described as an example of the filter for smoking articles. However, in addition to the cigarette, the cigarette filter may be applied to a cigar or cigarillo filter. Further, in addition to smoking articles with combustion such as cigarettes, cigars, cigarillos, etc., the present invention may be applied to a filter used for a smoking article that heats and sucks tobacco, or a smoking article that sucks tobacco without heating.
