Description

本発明は、タバコのような喫煙具用フィルタ及びフィルタ要素に関する。   The present invention relates to a filter and filter element for a smoking device such as tobacco.

リセスフィルタは、タバコ業界ではよく知られており、タバコ用に独特な固有の端部概観を与える。これらは、一般的に、比較的硬いプラグ巻紙を離れた距離にあるフィルタ区分の連続した流れに巻き付けることにより製造される。フィルタ区分（要素）が無い領域でフィルタ流れを切断することにより、リセスフィルタを得ることができる。硬いプラグ巻紙は、完成したタバコに製造すること、且つフィルタの露出された紙端が押し潰されることなく使用されることが可能な程度に十分な硬さを与える。   Recess filters are well known in the tobacco industry and provide a unique end view that is unique to tobacco. These are generally produced by wrapping a relatively stiff plug wrap around a continuous stream of filter sections at a distance. A recess filter can be obtained by cutting the filter flow in an area where there is no filter section (element). A hard plug wrap provides sufficient hardness to be able to be produced into a finished tobacco and used without the exposed paper edge of the filter being crushed.

リセスフィルタは、１、２又はそれ以上のフィルタ区分を包含することができる。もし、フィルタ内に活性炭又は他の微粒子添加物を包含することを望むのであれば、少なくとも２区分、即ち、喫煙者に（凹所又は空洞内で）剥き出しの白い端が出るように、一般的に、セルロースアセテートを含む、口側の端に最も近い区分と、繊維性マトリックス内で散在された炭素（又は他）粒を典型的に含む、タバコの柱状体に最も近い区分と、を使用することが必要となる。凹所内に微粒子添加物を包含させるために、少なくとも２区分を使用する必要性は、複雑さと、炭素リセスフィルタの製造コストを増す。何故なら、２区分フィルタのような炭素を有する区分内に包含可能な炭素重量を制限するからである。さらに、前記制限を越えると、フィルタの圧力降下の増加が、不満足な喫煙特性に導くため、例えば、従来の２区分極細型（例えば、円周１６ｍｍ）の活性炭含有リセスフィルタに密接に関係している。これらの問題を克服するリセスフィルタの必要性がある。   A recess filter can include one, two or more filter sections. If it is desired to include activated carbon or other particulate additives in the filter, it is common to have at least two sections, i.e., a smoker with a bare white edge (in a recess or cavity). The section closest to the mouth end, including cellulose acetate, and the section closest to the tobacco column, typically including carbon (or other) grains interspersed within the fibrous matrix. It will be necessary. The need to use at least two sections to include the particulate additive in the recess increases complexity and manufacturing cost of the carbon recess filter. This is because it limits the weight of carbon that can be included in a section having carbon, such as a two-section filter. Further, if the above limit is exceeded, an increase in the pressure drop of the filter leads to unsatisfactory smoking characteristics, so it is closely related to, for example, a conventional two-section ultra-fine type (for example, circumference 16 mm) activated carbon-containing recess filter. Yes. There is a need for a recess filter that overcomes these problems.

国際公開第２００６／０５９１３４号パンフレットInternational Publication No. 2006/059134 Pamphlet 英国特許第２，２６１，１５２号明細書British Patent 2,261,152

本発明によれば、タバコ煙濾過材料の単一の長手方向に延びる芯の周囲に係合された外側巻紙を具備するタバコ煙フィルタ（又はフィルタ要素）であって、前記外側巻紙の第１端は、前記外側巻紙が周囲に係合する前記芯の第１端と実質的に同一平面にあり、及び前記外側巻紙の第２端は、前記外側巻紙が周囲に係合する前記芯の第２端を越えて延びており、前記フィルタの第２端で空洞（例えば、筒状）を形成し、
前記フィルタ（又はフィルタ要素）は、さらに、前記外側巻紙の第２端及び／又は芯の第２端から離れた添加物（例えば、微粒子添加物）を含む。前記外側巻紙が周囲に係合する前記芯の前記第２端を越えて延びる前記外側巻紙の径方向内面は、リセスフィルタの第２端で（例えば、長手方向に延びる芯材の第２端と共に）空洞又は凹所、例えば、前記フィルタの第２端の筒状空洞／凹所を形成してよい。 In accordance with the present invention, a tobacco smoke filter (or filter element) comprising an outer wrapping engaged around a single longitudinal core of tobacco smoke filtering material, the first end of said outer wrapping paper. Is substantially flush with a first end of the core with which the outer web is engaged, and a second end of the outer web is a second of the core with which the outer web is engaged. Extending beyond the end, forming a cavity (eg, cylindrical) at the second end of the filter,
The filter (or filter element) further includes an additive (eg, a particulate additive) spaced from the second end of the outer web and / or the second end of the core. The radially inner surface of the outer web extending beyond the second end of the core with which the outer web is engaged is at the second end of the recess filter (e.g., with the second end of the core extending in the longitudinal direction). ) A cavity or recess may be formed, for example a cylindrical cavity / recess at the second end of the filter.

微粒子添加物は、前記巻紙及び／又は芯の第２端から離れているため、前記巻紙及び／又は芯の第２端から見えない。   The particulate additive is not visible from the second end of the wrapping paper and / or core because it is away from the second end of the wrapping paper and / or core.

一実施態様では、前記タバコ煙濾過材料の単一の長手方向に延びる芯は、添加物（例えば、微粒子添加物）が１又は（少なくとも１つの）ポケット内に完全に封入（埋め込み）されたタバコ煙濾過材料の棒状芯を含む。タバコ煙濾過材料の棒状芯は、棒状芯周囲に係合された追加的な巻紙（例えば、多孔質又は非多孔質）を任意選択的に有してよい。タバコ煙濾過材料の芯内の添加物が完全に封入されたポケットの提供は、（何故なら、添加物ポケットと前記芯端との間にタバコ煙濾過材料があるためである）前記芯の前記第２端から添加物が離されるという結果を生じる。   In one embodiment, the single longitudinally extending core of the tobacco smoke filter material is a cigarette in which an additive (eg, particulate additive) is completely encapsulated (embedded) in one or (at least one) pocket. Includes a rod-like core of smoke filter material. The rod-shaped core of tobacco smoke filtration material may optionally have additional wrapping paper (eg, porous or non-porous) engaged around the rod-shaped core. Providing a pocket in which the additive in the core of the tobacco smoke filter material is fully enclosed is because the tobacco smoke filter material is between the additive pocket and the core end. The result is that the additive is released from the second end.

タバコ煙濾過材料の単一の長手方向に延びる芯は、前記第１端（例えば、フィルタタバコのタバコ端）に近く、及び前記第２端（例えば、口又は口端）から離れて、添加物の単一のポケット（例えば、微粒子添加物）内に、完全に封入（又は埋め込み）されていてよい。タバコ煙濾過材料の単一の長手方向に延びる芯は、芯（たとえばフィルタタバコのタバコ端）の第１端と、芯の第２端（例えば、フィルタタバコの口又は口端に最も近い芯の端）との間と同一距離に配置された添加物（例えば、微粒子添加物）の単一のポケット内に完全に封入（例えば、埋め込み）されてよい。タバコ煙濾過材料の単一の長手方向に延びる芯は、添加物（例えば、微粒子添加物）の１以上に（例えば、２、３、４）分離したポケット内に完全に封入されてよい。添加物が完全に封入（又は埋め込み）されたポケットは、例えば、通常の楕円形状など、一端又は両端に向かうテーパであってよい。もし、１よりも多く添加物があるときは、長手方向に規則的間隔で配置されていてよい。また、製造工程の適切な調整によって達成することが可能な、例えば、より長い間隔と、比較的短い長手方向間隔と交互にするなど、他のポケット配置も可能である。添加物（例えば、微粒子添加物）の（又は少なくとも１つの）ポケット内と共に完全に封入（又は埋め込み）されたタバコ煙濾過材料の棒状芯を含むタバコ煙濾過材料の単一の長手方向に延びる芯は、例えば、国際公開第２００６／０５９１３４号パンフレットに開示された方法又は装置によって製造することができる。   A single longitudinally extending core of tobacco smoke filtration material is near the first end (eg, tobacco end of a filter cigarette) and away from the second end (eg, mouth or mouth end) In a single pocket (eg, a particulate additive). A single longitudinally extending wick of tobacco smoke filtration material has a first end of a wick (eg, tobacco end of a filter cigarette) and a second end of the wick (eg, the core closest to the mouth or mouth end of the filter cigarette). May be completely encapsulated (eg, embedded) in a single pocket of additive (eg, particulate additive) disposed at the same distance as the edge. A single longitudinally extending core of tobacco smoke filtration material may be completely enclosed in one or more (eg, 2, 3, 4) separate pockets of the additive (eg, particulate additive). The pocket in which the additive is completely encapsulated (or embedded) may be tapered toward one or both ends, for example, a normal oval shape. If there is more than one additive, they may be arranged at regular intervals in the longitudinal direction. Other pocket arrangements are also possible that can be achieved by appropriate adjustment of the manufacturing process, for example alternating with longer intervals and relatively shorter longitudinal intervals. A single longitudinally extending core of tobacco smoke filtration material comprising a rod-shaped core of tobacco smoke filtration material fully encapsulated (or embedded) within (or at least one) pocket of an additive (eg, particulate additive) Can be produced, for example, by the method or apparatus disclosed in WO 2006/059134.

従って、本発明によれば、タバコ煙濾過材料の単一の長手方向に延びる芯の周囲に係合された外側巻紙を具備するタバコ煙フィルタを提供する。
タバコ煙濾過材料の単一の長手方向に延びる芯は、添加物（例えば、微粒子添加物）の１または（少なくとも１つの）ポケット内に完全に封入（埋め込み）されたタバコ煙濾過材料の棒状芯を具備する。
前記外側巻紙の第１端は、前記外側巻紙が周囲に係合する前記芯の第１端と実質的に同一平面にあり、前記外側巻紙の前記第２端は、前記フィルタの前記第２端で空洞（凹所）を形成するように、前記外側巻紙が周囲に係合する前記芯の前記第２端を越えて延びる。 タバコ煙濾過材料の棒状芯は、棒状芯周囲に係合された追加的な巻紙を有する。前記外側巻紙が周囲に係合する前記芯周囲の前記第２端を越えて延びる前記外側巻紙の半径方向内面には、前記フィルタの前記第２端に（例えば、前記長手方向に延びる芯の前記第２端と共に）空洞又は凹所、例えば、筒状空洞／凹所を形成する。 Thus, in accordance with the present invention, a tobacco smoke filter is provided that comprises an outer wrapping paper that is engaged around a single longitudinal core of tobacco smoke filtration material.
A single longitudinally extending core of tobacco smoke filtration material is a rod-shaped core of tobacco smoke filtration material completely enclosed (embedded) within one or (at least one) pocket of additive (eg, particulate additive) It comprises.
The first end of the outer web is substantially flush with the first end of the core around which the outer web engages, and the second end of the outer web is the second end of the filter. The outer web extends beyond the second end of the core that engages the periphery so as to form a cavity. The rod-shaped core of tobacco smoke filtering material has an additional wrapping paper engaged around the rod-shaped core. A radially inner surface of the outer web that extends beyond the second end around the core with which the outer web engages is disposed on the second end of the filter (e.g., the length of the core extending in the longitudinal direction). Along with the second end, a cavity or recess is formed, for example a cylindrical cavity / recess.

他の実施の形態では、前記タバコ煙濾過材料の単一の長手方向に延びる芯は、タバコ煙濾過材料の棒状芯と、前記棒状芯の周囲に係合し、添加物（例えば、微粒子添加物）を有する巻紙を具備し、前記添加物を有する巻紙は、前記半径方向内面の１以上の部分に付着された添加物を有しており、前記芯の前記第２端における該巻紙の円周にわたって前記添加物が無い。添加物（例えば微粒子添加物）有する巻紙の前記第２端に添加物が無いことは、（前記芯の前記第２端の前記巻紙の円周囲に添加物が無いため）前記芯の前記第２端から前記添加物が離されるという効果がある。好ましくは、前記添加物を有する巻紙は、前記芯の第１及び第２端両方の円周にわたって添加物が無い。前記タバコ煙濾過材料の長手方向に延びる芯は、タバコ煙濾過材料の前記棒状芯と、棒状芯周囲に係合された添加物（例えば微粒子添加物）を有する巻紙を具備し、前記タバコ煙濾過材料の単一の長手方向に延びる芯は、英国特許第２２６１１５２号公報に開示されたフィルタ要素であってよい。前記添加物（例えば微粒子添加物）を有する包装は、多孔質又は非多孔質であってよい。   In another embodiment, a single longitudinally extending wick of the tobacco smoke filter material engages the rod wick of tobacco smoke filter material and the periphery of the rod wick, and an additive (eg, particulate additive) The wrapping paper having the additive has an additive attached to one or more portions of the radially inner surface, and the circumference of the wrapping paper at the second end of the core There is no such additive over time. The fact that there is no additive at the second end of the wrapping paper having an additive (for example, a fine particle additive) means that the second end of the wick (because there is no additive around the wrapping paper circle at the second end of the wick). There is an effect that the additive is separated from the end. Preferably, the wrapping paper having the additive has no additive over the circumference of both the first and second ends of the core. A core extending in the longitudinal direction of the tobacco smoke filtering material comprises a wrapping paper having the rod-shaped core of tobacco smoke filtering material and an additive (for example, a fine particle additive) engaged around the rod-shaped core, and the tobacco smoke filtration A single longitudinally extending core of material may be the filter element disclosed in GB 2261152. A package having the additive (eg, particulate additive) may be porous or non-porous.

従って、本発明によれば、タバコ煙フィルタは、タバコ煙濾過材料の単一の長手方向に延びる芯周囲に係合された外側巻紙を具備するタバコ煙フィルタを提供し、そこで、前記外側巻紙の第１端は、前記外側巻紙が周囲に係合する前記芯の第１端と実質的に同一平面にあり、及び前記外側巻紙の前記第２端は、前記フィルタの前記第２端の（例えば、筒状の）空洞を形成するように、前記外側巻紙が周囲に係合する前記芯の第２端を超えて延びる。
前記タバコ煙濾過材料の単一の長手方向に延びる芯は、タバコ煙濾過材料の棒状芯と、棒状芯周囲に係合された添加物（例えば、微粒子添加物）有する巻紙と、を具備する。前記添加物を有する巻紙は、前記半径方向内面に１以上の部分に付着された添加物を有しており、前記芯の前記第２端における円周にわたって添加物が無い。前記外側巻紙が周囲に係合する前記芯の前記第２端を越えて延びる外側巻紙の半径方向内面は、（例えば、長手方向に延びる芯の第２端と共に）空洞又は凹所、例えば、リセスフィルタの前記第２端の筒状空洞／凹所を形成する。 Thus, according to the present invention, a tobacco smoke filter provides a tobacco smoke filter comprising an outer wrapping engaged around a single longitudinally extending core of tobacco smoke filtering material, wherein the outer wrapping of the outer wrapping paper is provided. The first end is substantially flush with the first end of the core around which the outer web is engaged, and the second end of the outer web is the second end of the filter (e.g., The outer wrapping extends beyond the second end of the core that engages the periphery so as to form a (cylindrical) cavity.
The single longitudinally extending core of the tobacco smoke filter material comprises a rod-shaped core of tobacco smoke filter material and a wrapping paper having additives (eg, particulate additives) engaged around the rod-shaped core. The wrapping paper having the additive has the additive attached to one or more portions on the radially inner surface, and there is no additive over the circumference at the second end of the core. A radially inner surface of the outer web that extends beyond the second end of the core with which the outer web is engaged is a cavity or recess, such as a recess (eg, with the second end of the longitudinally extending core). Form a cylindrical cavity / recess at the second end of the filter.

更なる実施の形態では、前記外側巻紙は、添加物（例えば、微粒子添加物）を有してよく、その添加物は、前記巻紙の前記第２端で円周囲の添加物が無い前記外側巻紙と共に、半径方向内面の１以上の部分に付着されている。前記外側巻紙は、（前記第１端に向かって）前記巻紙の前記第２端から延びる領域で添加物が無くてよい。前記領域は、好ましくは、少なくとも、前記空洞を形成するように、前記巻紙に係合する前記芯の前記第２端を超えて延びる前記巻紙の前記第２端による距離よりも大きい。よって、前記フィルタの第２端で前記空洞を形成するように、前記巻紙に係合する前記芯の前記第２端を超えて延びる前記巻紙の内面は、その円周にわたって添加物はない。このため、前記空洞の壁内面上に添加物は無い。   In a further embodiment, the outer wrapping paper may have an additive (eg, a particulate additive), the additive being free from a circular additive at the second end of the wrapping paper. At the same time, it is attached to one or more portions of the radially inner surface. The outer wrapping paper may be free of additives in a region extending from the second end of the wrapping paper (toward the first end). The region is preferably at least greater than the distance by the second end of the wrapping paper that extends beyond the second end of the core that engages the wrapping paper so as to form the cavity. Thus, the inner surface of the wrapping paper extending beyond the second end of the core that engages the wrapping paper is free of additives over its circumference so as to form the cavity at the second end of the filter. For this reason, there is no additive on the inner wall surface of the cavity.

本出願人は、本発明の態様によれば、「モノカーボン」フィルタをリセスフィルタに効果的、且つ有利に含んでもよいことを見出した。例えば、例えば、１工程で製造することができる、（例えば、英国特許第２，２６１，１５２号明細書に開示された「アクティブパッチ」フィルタ、又は、国際公開第２００６／０５９１３４号パンフレットに開示された、「スムース芯フィルタ」を含む）例えば、フィルタ材料の単一の長手方向に延びる芯及び少なくとも１端に添加物が無い添加物（例えば、炭素）を包含するフィルタなど。クレームされたフィルタ（リセスフィルタ）は、改良された感覚的な性質を提供してよい。何故なら、（例えば、スムースコアフィルタの中央の「ポッド」、又は「スムース芯」 のポケット内、又は、「アクティブパッチ」フィルタのプラグ巻紙の周辺炭素の位置を制御することにより）フィルタ内の煙流れの炭素との接触を、より制御することができる。そして、煙流が喫煙者の口に流入し、及び口蓋に作用する前に、凹所内で循環し、且つ混合することを可能にするからである。添加物が無い端を有する濾過材料の単一の長手方向に延びる芯の、リセスフィルタ内の「基部ロッド」としての使用は、添加物、例えば、炭素リセスフィルタを含むリセスフィルタの製造コスト及び複雑さを著しく減少させることができる。これは、従来の炭素リセスフィルタのような２以上の区分ではなく、単一のフィルタ構成要素に切断し、調整するのみでよいからである。   Applicants have found that, according to aspects of the present invention, a “monocarbon” filter may be effectively and advantageously included in the recess filter. For example, it can be manufactured in one step (for example, disclosed in British Patent 2,261,152, disclosed in “Active Patch” filter, or in WO 2006/059134). Also, including a “smooth core filter”, for example, a filter that includes a single longitudinally extending core of filter material and an additive (eg, carbon) that has no additive at least at one end. The claimed filter (recess filter) may provide improved sensory properties. This is because the smoke in the filter (eg, by controlling the position of the carbon around the plug wrap of the “patch” or “smooth core” in the center of the smooth score filter, or the plug wrapper of the “active patch” filter) The contact of the stream with carbon can be more controlled. This is because it allows the smoke stream to circulate and mix in the recess before entering the smoker's mouth and acting on the palate. The use of a single longitudinally extending core of filtration material having an additive-free end as a “base rod” in a recess filter makes the manufacturing cost and complexity of an additive, for example, a recess filter including a carbon recess filter, Can be significantly reduced. This is because it is only necessary to cut and adjust to a single filter component rather than two or more sections as in conventional carbon recess filters.

極細型リセスフィルタの棒状芯周囲に係合され、添加物を有する巻紙と、タバコ煙濾過材料の棒状芯の使用は、満足のいくフィルタの圧力低下及び喫煙体験を維持しつつ、従来の超薄型炭素リセスフィルタ用に使用されるよりも、高い炭素重量の使用を可能にする。   The use of a wrapping paper that is engaged around the rod core of an extra-fine recess filter, with additives, and a rod core of tobacco smoke filtration material, allows the conventional ultra-thin while maintaining a satisfactory filter pressure drop and smoking experience. Allows the use of higher carbon weight than is used for type carbon recess filters.

濾過材料は、例えば、（通常は、フィラメント状、繊維状、ウエブ状、又は、押出のような）慣例的にタバコ煙フィルタ製造で使用される、これらの材料のいくつかであってよい。濾過材料は、天然又は、合成フィラメント状トウ、例えば、綿、又は、ポリエチレン、又は、ポリプロピレン、又はセルロースアセテートフィラメント状トウのようなプラスチックであってよい。例えば、天然又は、合成ステープル繊維、綿毛、（通常はクレープ織り）紙のようなウエブ材料及び合成不織布、及び押出材料（例えば、澱粉、合成泡状物質）であってよい。   The filtering material may be some of these materials that are conventionally used in tobacco smoke filter manufacture (usually filamentous, fibrous, web-like, or extruded), for example. The filtering material may be a plastic, such as natural or synthetic filamentous tow, for example cotton or polyethylene or polypropylene or cellulose acetate filamentous tow. For example, it can be natural or synthetic staple fibers, fluff, web materials such as paper (usually creped) and synthetic nonwovens, and extruded materials (eg starch, synthetic foam).

添加物は、微粒子添加物であってよい。微粒子添加物は、タバコ煙フィルタ用途に適したいかなる微粒子添加物であってよい。例えば、活性炭、ゼオライト、イオン交換樹脂（例えば、弱基アニオン交換樹脂）、セピオライト、シリカゲル、アルミナ、モレキュールシーブ、炭素ポリマ樹脂及び珪藻土。微粒子添加物は、２又はそれ以上の材料の混合であってよい。添加物は、香料を含んでよい。例えば、メントールである。例えば、添加物は、メントールが適用されたセピオライト粒であってよい。もし、タバコ煙濾過の長手方向に延びる芯が、添加物を完全に封入（例えば、埋め込み）されたポケットを含む場合、添加物は、活性炭（上記参照）のような微粒子添加物であってよく、それは、例えば、実質的に分離された微粒子添加物の粒子の別個のポケットやポッドとして、濾過材料内に封入された実施例として、濾過材料が完全に封入される。他の実施形態では、添加物が完全に封入（埋め込み）されたポケットは、１又は複数のカプセルの壊れ易い、１又は複数の壊れ易いマイクロカプセルであってよい。カプセルやマイクロカプセルは、例えば、香料、及び／又は液体、固体、又はその他の材料、例えば、煙濾過を助けるための、多様な媒体を含んでよい。カプセル又はマイクロカプセルの使用は、業界では周知である。   The additive may be a fine particle additive. The particulate additive can be any particulate additive suitable for tobacco smoke filter applications. For example, activated carbon, zeolite, ion exchange resin (for example, weak group anion exchange resin), sepiolite, silica gel, alumina, molecular sieve, carbon polymer resin, and diatomaceous earth. The particulate additive may be a mixture of two or more materials. The additive may include a fragrance. For example, menthol. For example, the additive may be sepiolite granules with menthol applied. If the longitudinal core of the tobacco smoke filter includes a pocket that is fully encapsulated (eg, embedded), the additive may be a particulate additive such as activated carbon (see above). For example, the filtration material is completely encapsulated, for example as a separate pocket or pod of particles of substantially separated particulate additive, encapsulated within the filtration material. In other embodiments, the pocket fully encapsulated (embedded) with the additive may be one or more fragile one or more fragile microcapsules. Capsules and microcapsules may contain, for example, fragrances and / or liquids, solids, or other materials, such as a variety of media to aid in smoke filtration. The use of capsules or microcapsules is well known in the industry.

タバコ煙フィルタは、長さ１５〜４０ｍｍであってよく、例えば、１７〜３５ｍｍ、例えば、２０〜３０ｍｍである。フィルタ先端の凹所部分（すなわち、フィルタの第２端（例えば、口）の空洞を形成するように、前記外側巻紙が周囲に係合する芯の第２端を超えて延びる外側巻紙の第２端による長さ）は、３〜１０ｍｍ長さであってよい。及び最適には４〜６ｍｍ長さである。タバコ煙フィルタの単一の長手方向に延びる芯は、１０〜３０ｍｍ長さであってよく、例えば、１４〜２７ｍｍ、例えば、１７〜２５ｍｍである。タバコ煙フィルタは、円周１４〜２８ｍｍであってよく、例えば、１６〜２６ｍｍ、例えば、１６〜１７ｍｍ、又は２４〜２５ｍｍである。最終的なタバコは、通気性又は非通気性、及び喫煙製品で伝統的に使用されるいかなる円周範囲（例えば、円周１４〜２８ｍｍ）であってよい。   The tobacco smoke filter may be 15-40 mm long, for example, 17-35 mm, for example 20-30 mm. A second portion of the outer web that extends beyond the second end of the core with which the outer web is engaged so as to form a cavity in the recessed portion of the filter tip (ie, the second end (eg, mouth) of the filter). The length by the end) may be 3-10 mm long. And optimally it is 4-6 mm long. The single longitudinally extending core of the tobacco smoke filter may be 10-30 mm long, for example 14-27 mm, for example 17-25 mm. The tobacco smoke filter may have a circumference of 14-28 mm, for example, 16-26 mm, such as 16-17 mm, or 24-25 mm. The final tobacco can be breathable or non-breathable and any circumferential range traditionally used in smoking products (eg, 14-28 mm circumference).

外側巻紙は、紙、例えば、プラグ巻紙であってよく、例えば、硬いプラグ巻紙である。外側巻紙は、多孔質、又は非多孔質であってよい。外側巻紙は、基本重量が４０〜１２０ｇ／ｍ2の紙であってよい。外側巻紙は、例えば、標準円周（２４〜２５ｍｍ）のリセスフィルタ用に、基本重量が８０〜１２０ｇ／ｍ2であってよく、例えば、約１００ｇ／ｍ2、の紙である。細型又は極細型リセスフィルタ（例えば、円周約１６〜１７ｍｍまで）、外側巻紙は、例えば、約５０ｇ／ｍ2のより低基本重量のプラグ巻紙であってよい。 The outer wrapping paper may be paper, for example, plug wrapping paper, for example, hard plug wrapping paper. The outer wrapping paper may be porous or non-porous. Outer paper wrapper, the basic weight may be a paper 40 to 120 g / m 2. Outer paper wrapper, for instance, the recesses filter standard circumference (24~25mm), better basis weight a 80 to 120 / m 2, for example, about 100 g / m 2, which is a paper. The fine or ultra-fine recess filter (e.g., up to about 16-17 mm circumference), the outer wrapping may be a lower basis weight plug wrap, for example, about 50 g / m < 2 >.

約４０〜１２０ｇ／ｍ2の基本重量の外側巻紙は、「アクティブパッチ」フィルタに関連した可能性のある欠点を克服することができる。それは、使用済フィルタ又はタバコを持つときに、添加物を有する巻紙の内面表面に付着された炭素粒の存在を感じる可能性がある。形成されたフィルタ（例えば、約４０〜１２０ｇ／ｍ2の基本重量の外側巻紙を含む）は、（例えば、「アクティブパッチ」フィルタ構成要素）に使用されるべき微粒子添加物のより大きな粒サイズを可能にする。何故ならば、使用済のタバコの外側上で、（基本重量がより重く、巻紙の「硬さ」が増したことにより）、そのような粒の存在は感じられず、又は、より感じ難くなっているためである。 An outer wrapper with a basis weight of about 40-120 g / m 2 can overcome possible drawbacks associated with “active patch” filters. It may feel the presence of carbon particles attached to the inner surface of the wrapping paper with additives when having a used filter or tobacco. The formed filter (eg, including an outer wrapper with a basis weight of about 40-120 g / m 2 ) provides a larger particle size for the particulate additive to be used (eg, an “active patch” filter component). to enable. Because on the outside of the used cigarette (because the basis weight is heavier and the “hardness” of the wrapping paper increased), the presence of such particles is not felt or is less likely to be felt. This is because.

本発明によるフィルタタバコでは、本発明のフィルタ（又は、本発明のフィルタ要素を含むフィルタ）は、タバコ側にフィルタの一端と共に包装されたタバコロッドに結合されている。フィルタは、例えば、（フィルタ巻紙の露出部分の多くを残すように（包装された）フィルタ及びロッドの隣接端周囲のみを係合する）先端部輪により包装されたタバコロッドに結合されてもよい。又は、より好ましくは、フィルタは（フィルタ全長及びタバコロッドの隣接端の周囲に係合する）完全な先端部の重なりにより、包装されたタバコロッドに結合されてよい。
タバコは、完成したリセスフィルタタバコに、所望の（例えば、より増加した）硬さを与えるために、フィルタの外側巻紙と結合する先端部重なり（例えば、硬い先端部の紙）を含んでよい。 In a filter cigarette according to the present invention, the filter of the present invention (or a filter comprising the filter element of the present invention) is coupled to a tobacco rod packaged with one end of the filter on the tobacco side. The filter may be coupled, for example, to a tobacco rod packaged with a tip ring (engaging only around the adjacent end of the filter and the rod (packaged) to leave much of the exposed portion of the filter wrapper). . Or more preferably, the filter may be coupled to the packaged tobacco rod by full tip overlap (engaging around the entire length of the filter and adjacent ends of the tobacco rod).
The cigarette may include a tip overlap (eg, hard tip paper) that mates with the outer wrapping paper of the filter to give the finished recess filter tobacco the desired (eg, increased) hardness.

The complete overlap of the breathable tips may be essentially air permeable or similar to the disposed breathable holes. The overlap of the filter plug wrapping paper and the leading end will normally be aligned through the plug wrapping paper where air permeability exists through the overlap. Breathable holes that pass through the filter plug wrap, or through the tip overlap, or both at the same time, may be formed by laser drilling during the manufacture of the filter or filter cigarette.

本発明によるフィルタ又はフィルタタバコの通気性は、製品の長手方向に局部集中し、この局部集中は、好ましくは、及び、要求された通気性及びフィルタ性能により、第１の添加物のポケット（又は、パッチ、又は部分）と整列して、上流、下流、から選択された１又は２の領域となる。上流の、及び／又は、第１の添加物のポケットと共に整列した通気性がしばしば好まれる。２以上の添加物が存在するときには、第２の添加物の部分（又は、ポケット、又はパッチ）の間の通気性があってもよい。   The breathability of the filter or filter cigarette according to the invention is locally concentrated in the longitudinal direction of the product, and this localized concentration is preferably, and depending on the required breathability and filter performance, the first additive pocket (or , A patch, or a portion) to be one or two regions selected from upstream and downstream. Aligned breathability with upstream and / or first additive pockets is often preferred. When more than one additive is present, there may be breathability between portions (or pockets or patches) of the second additive.

FIG. 4 shows a tobacco smoke filter 101 comprising an outer web 103 of plug wrap with a basis weight of 100 g / m 2 engaged around a single longitudinal core of tobacco smoke filtration material 105. The single longitudinally extending core of the tobacco smoke filter material 105 is, for example, a pod filter disclosed in WO 2006/059134. The wick 105 is completely encapsulated (eg, embedded) in an additive pocket 199 in the form of activated carbon and includes a rod wick 107 of tobacco smoke filtration material in the form of cellulose acetate tow. The first end 103a of the outer web 103 is substantially flush with the first end 105a of the core around which the outer web engages, and the second end 103b of the outer web is the cavity 106, i.e. the filter. The outer web extends beyond the second end 105b of the core that engages the periphery so as to form a recess at the second end (mouth side). A radially inner surface of the outer wrapping paper 103 extending beyond the second end of the core 105b forms a cylindrical cavity (recess) 106 together with the second end of the longitudinally extending core 105b on the second end or mouth side of the filter. It will be understood that it forms. Alternatively, the filter 101 has a length of 27 mm, and the second end cavity 106, i.e. the recess, has a length of 6 mm. Pocket 199 is located near the first or tobacco end of wick 107. However, it will be appreciated that the wick 107 has ends without additive (since the additive is completely embedded within the wick).
The additive is not visible from the second or mouth end of the filter. The pod filter element 107 is manufactured by, for example, a method disclosed in International Publication No. 2006/059134. Methods for including a filter element within a recess filter are well known, and those skilled in the art will readily understand how to include a pod filter element in a recess filter to provide a recess filter according to the present invention.
