200840494 九、發明說明： 【發明所屬之技術領域】 本發明大體有關於用於過濾菸草煙的裝置及其製造及 使用。更特別的是，本發明係有關於適合使用於吸煙装^ 5的濾嘴。 【先前技術】 • 使用一次、用完即棄的濾嘴成為吸煙產品已有數十 年。濾嘴一般是用纖維素乙酸酯溶解於溶劑（例如，丙酮） 以及由心液紡出聚合物細絲的方法由纖維素乙酸酯 (cellulose acetate)製成。該等細絲係經潤滑及製作成 捆，然後卷曲並乾燥。替代性濾嘴材料包含聚丙烯與纖 、准素濾鳴可分段，不同的小段可用不同的材料；彼等可 加入粒狀添加物，例如碳。 15 濾嘴是位於菸草棒（t〇bacco rod)之一末端，藉此在 _ ，用者用濾嘴吸煙入口之前，燃燒菸草棒的煙（由粒相及 氣相構成）會通過濾嘴。濾嘴的纖維形成能捕獲煙流中之 顆粒物質的機械屏障。先前技術的濾嘴係依靠這種機械過 %濾；，如，請參考美國專利第4,5〇2,495號。 2〇 =近的方法則包含沿著濾嘴外的包裝紙提供可稀釋吸 務的通風孔。彼等也以煙中通常不受濾嘴之物理屏障 y曰的揮务組份為目標。例如，常添加吸附劑或吸收劑材 料以選擇性去除煙流的揮發元素。 /舌丨生奴、諸如海泡石（meerschaum )之類的多孔鑛物、 5 200840494 石夕膠、以及陽離子或陰離子交換樹脂常被用來作為渡嘴添 加物。碳或木炭用來去除酸氣很有用。海泡石對於帶電物 種有強吸附力（adsorption affinity)。石夕朦可輕易吸收 乙醛及氫氰酸（hydrogen cyanide)。已有人提議用陽離子 5交換樹脂來去除尼古丁，而有人提議是用陰離子交換樹脂 來去除煙中酸類。研發人員持續在開發以特定煙組份 (smoke constituent)或煙組份類為目標的新式添加物。 添加粒狀或顆粒材料於濾嘴細絲要面對的挑戰之一是 如何以仍能保持活性的方式來黏上個別的微粒。例如，使 10微粒固定於纖維的黏著劑可能會擋住微粒的反應部位 (reaction site)。解決方案之一是在濾嘴中形成空腔並 裝進一批微粒，然而這會有不同的問題，亦即，在使用時 如何引導煙流通過這批鬆散的微粒。 另一個微粒容納的解決方案是密封微粒於與煙流方向 I5平行的管子中，藉此煙會穿過管子而且與其中的微粒接 觸。如美國專利弟4, 373, 539號所述，藉由製成非線性的 管子’過滤、的路控會比較長些。 其他的習知濾嘴例子揭示於W0 86/03381號、美國專 利第2003/0200973號、以及歐洲專利第EP-A 0033772 #， 2〇 該等文獻係描述各種對於煙有螺旋通道的濾嘴。 由於本技藝仍亟須減少煙中的粒狀及氣相組份，因此 希望有新的材料與方法可用來改善現有的濾嘴。特別是， 可用來與各種習知或新穎濾嘴材料及添加物結合的解決方 案是特別有利的。 6 200840494 【發明内容】 根據本發明’提供—種用於於草產品的煙渡嘴，其中 有-段滤嘴是軸向延伸成可界定一條在使用時煙會沿著它 5穿過過滤材料的路徑，該路經係繞著滤嘴的轴線延伸成螺 旋形。藉由以此方式提供園繞著濾嘴轴線的煙路徑，可增

件與該圍封物的内層之間的整個空間。這可確保沿著該螺 旋形元件流動之煙一定會穿過該過濾構件，藉此可提供優 良的過濾性能。此外，緊密裝填該過濾構件於該濾嘴内可 使該濾嘴有結實可靠的感覺。使用小纖維或類似的過濾材 15料可實現這種緊密裝填。 馨 根據另具體貝細*例，長1供一種吸煙物件（smoking ar t i c 1 e ) ’其係包含本發明的於草煙濾嘴。

在螺旋核心為結實堅挺的材料時，在螺旋體外四周最 好以共軸方式設有緊緊地包著纖維素乙酸酯的區域以使得 在使用時濾嘴有與標準濾嘴極為相似的感覺。也可調整長 度，例如它可為標準濾嘴的一部份以容納一或更多濾嘴元 10 件於一端或兩端。 為了提供有標準樣子的濾嘴，在使用者可看見.的吸煙 物件口腔端最好有一小段是纖維素乙酸酯的濾嘴，使得本 發明的多段濾嘴在使用者那端的一半是纖維素乙酸酯而在

5心對應的螺旋圖樣中，加上通風孔是最有效的。在決定是 否使用通風孔時，要考慮壓降，因為通風孔的數目及位置 是取決於螺旋體的形狀與材料以及使用之過濾構件的考慮 事項。 可用任何適當的方法來製造本發明的螺旋核心。特定 10的生產技術要求則取決於選定的材料與尺寸，以及螺旋核 心上是否有塗層。例如，在習知的濾嘴製程期間，纖維素 乙酸酯可夾帶壓出核心。 該螺旋核心以及與圍封物有關的位置會導致吸入煙流 在通過濾嘴到達使用者之前有比標準還長的迂迴路徑。這 15可增加過濾的表面積及時間。因此，螺旋核心本身為一種 過濾構件。 如果封入的螺旋核心只被周遭空氣包圍，吸入煙霧則 由於在進入使用者口腔之前僅僅需要行進較長的路徑而沒 有儘可能地加以過濾。較長的路徑玎用來冷卻空氣，而一 些顆粒物質可能會沉澱並黏著於核心或周圍的紙張。即使 螺旋物核心本身由過濾材料構成，以及即使此一螺旋核心

IX. DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates generally to apparatus for filtering tobacco smoke, and to the manufacture and use thereof. More particularly, the present invention relates to filters suitable for use in smoking devices. [Prior Art] • It has been a smoking product for decades to use a disposable filter. The filter is generally made of cellulose acetate by dissolving cellulose acetate in a solvent (for example, acetone) and spinning the polymer filament from the heart liquid. The filaments are lubricated and bundled, then crimped and dried. Alternative filter materials include polypropylene and fiber. The plain filter can be segmented. Different sections can be made of different materials; they can be added with granular additives such as carbon. 15 The filter is located at one end of the t〇bacco rod, whereby the smoke (composed of the grain phase and the gas phase) that burns the tobacco rod passes through the filter before the user uses the filter to smoke the inlet. The fibers of the filter form a mechanical barrier that captures particulate matter in the plume. Prior art filters rely on such mechanical filtration; for example, see U.S. Patent No. 4,5,2,495. 2〇 = The near method consists of providing venting holes for diluting sorption along the wrapper outside the filter. They also target the components of the smoke that are not normally subject to the physical barrier of the filter. For example, an adsorbent or absorbent material is often added to selectively remove volatile elements of the plume. / Tongue slaves, porous minerals such as meerschaum, 5 200840494, and cationic or anion exchange resins are often used as a nozzle addition. Carbon or charcoal is useful for removing sour gas. Sepiolite has an adsorption affinity for charged species. Shi Xiyu can easily absorb acetaldehyde and hydrogen cyanide. It has been proposed to use a cation 5 exchange resin to remove nicotine, and it has been proposed to use an anion exchange resin to remove acids from the smoke. Researchers continue to develop new additives that target specific smoke constituents or smoke components. One of the challenges of adding granular or particulate materials to filter filaments is how to adhere individual particles in a manner that remains active. For example, an adhesive that immobilizes 10 particles to the fiber may block the reaction site of the particles. One solution is to form a cavity in the filter and load a batch of particles, however this has a different problem, namely how to direct the flow of smoke through the batch of loose particles during use. Another solution for particle containment is to seal the particles in a tube parallel to the direction of flow I5, whereby the smoke will pass through the tube and contact the particles therein. As described in U.S. Patent No. 4,373,539, the path of filtration by making a non-linear tube will be longer. Other examples of conventional filters are disclosed in WO 86/03381, U.S. Patent No. 2003/0200973, and European Patent No. EP-A 0 033 772 #, 2 〇. These documents describe various filters having spiral passages for smoke. Since the art still does not require the reduction of particulate and gas phase components in the smoke, it is desirable to have new materials and methods for improving existing filters. In particular, solutions that can be used in conjunction with various conventional or novel filter materials and additives are particularly advantageous. 6 200840494 SUMMARY OF THE INVENTION According to the present invention, there is provided a soot nozzle for use in a grass product, wherein the segmented filter is axially extended to define a strip of smoke that will pass through the filter material along it during use. The path of the path extends spiral around the axis of the filter. By providing a smoke path around the axis of the filter in this manner, the contact time of the smoke with the filter, the material contact, and the surface area in contact with the filter and the material can be increased. According to an embodiment of the present invention, a tobacco smoke filter is provided, 10 comprising: an enclosure having an inner diameter, which is substantially cylindrical, and has a diameter and is disposed in the enclosure A helical 7G member among the objects, wherein the diameter of the spiral element is approximately equal to the inner diameter of the enclosure. The filter further includes a filter member (means) disposed between the spiral element and the 5 sea seal. 15 The enclosure may include a plug wrap that may include a plurality of vents. If so, the vents can be configured to correspond to areas of the enclosure that do not cover the spiral element. The enclosure has at least two layers, for example, the outer layer is a formed paper and the inner layer adjacent to the spiral element is cellulose acetate vinegar. 20 The spiral element may comprise polypropylene, polyethylene, paper, carbon paper, impregnated paper, or any other material mentioned herein and may include a coating on the outer surface. The coating may comprise activated charcoal, activated coconut carbon, activated coal-based carbon, zeolite, Shi Xi 7 200840494 I, sepiolite, oxidized, carbonized resin (carbonaceous resin), and combinations thereof. The spiral element may comprise a compressible edge at a point of contact with the inner layer of the enclosure. Alternatively or additionally, the central portion of the spiral core can be compressed. 5 The filter member may comprise at least one selected from the group consisting of cellulose acetate, polypropylene, polyethylene, gathered paper, and combinations thereof, for example, randomly oriented fibers. Acid acetic acid _ vinegar. The filter member may further comprise: activated carbon, a flavorant, an adsorbent, or an absorbent. In a specific embodiment, the filter member occupies the entire space between the spiral element and the inner layer of the enclosure. This ensures that the smoke flowing along the spiral element will surely pass through the filter member, thereby providing excellent filtration performance. In addition, the tight loading of the filter member within the filter provides a robust and reliable feel to the filter. This compact filling can be achieved using small fibers or similar filter materials. According to another specific example, the length 1 is for a smoking article (smoking ar t i c 1 e )' which comprises the grass smoke filter of the present invention. According to another embodiment, the present invention is directed to a method of manufacturing a grass smoke filter comprising the steps of: providing a generally cylindrical helix having a helical inner space and having a spiral inner space The outer edge, the filter member is disposed in the inner space of the spiral, and the outer edge of the pre-filled spiral is sealed in a surrounding. As used herein, "tobacco" refers to any part of the genus Nicotiana (e.g., leaves, flowers, stems) and recombinant materials thereof. It contains, for example, derivatives of specific compounds in the grass (e.g., nicotine, whether extracted or synthesized), as well as structural derivatives such as fiber fractions in tobacco leaves. It also contains tobacco substitutes consisting of individual chemicals and/or complex chemical molecules that, when properly prepared, are similar to natural tobacco. As used herein, "tobacco smoke filter" refers to any element intended to be used as a unit for the passage of tobacco smoke and for slowing, cooling and/or retaining its components. Tobacco smoke contains combustion by-products of tobacco and heating by-products that are not actually burned in the early stages. [Embodiment] The present invention relates to a tobacco smoke filter having a spiral element located at a central axis. The cross section of the component can take any of a variety of configurations, however, the component is described herein as a single spiral. Fig. 1 is a view showing a smoke 15 grass smoke filter 10 having a spiral core 11. As shown in the specific embodiment of Fig. 1, the spiral core is provided with a filter member 12. The spiral core 11 and the filter member 12 are visible due to the partial peeling of the enclosure 13 (which is shown as a forming paper). The spiral core 11 has a diameter approximately equal to the inner diameter of the enclosure 13. That is, the outer edge of the spiral is substantially next to the enclosure. The filter member 12 is located in a groove formed between the spiral core 11 and the enclosure 13 at the edge of the spiral body. As is well known to product engineers, the curve of the spiral can be moved from the lower left corner to the upper right corner to become a right-handed helix, or moved from the lower right corner to the upper left corner to become a left-handed helix. Both right-handed or left-handed spirals are used as the spiral core of the present invention. 9 200840494 The pitch of the spiral (that is, the length of one turn) plus the need for filtering, path and inhalation is easy. The material of the rotating element (especially whether it is 3 or not equal to ... mm, : Sound; to wind, temple, etc. The spacing can be excellent:: snail: the core material has a low permeability, ..., the hole is effective. That is, the number of holes is less attached to the spiral Make sure to shout in the smoke sucker and provide an opportunity to increase the removal of the tobacco book. Extruded (ext_ed) plastic film, Λ = minus are examples of materials that can form a spiral core. ί Rhyme (4), test Difficult to core (4) material is porous. 15 20 = material (4) hole made into Ke Teqing to catch, for example, 'this material can be molecularly imprinted with the target component (mQlecu = yr = ? polymer. Among the materials The pores may be filled with an additive, such as food 2. In the first few uses, the additive may be inhaled and left to pass through the interaction of the smoke flow. The spiral core may be formed by the active stone, and the density of the activated carbon is such that most The smoke is agitated around the spiral and a small portion of the smoke passes through The carbon structure of the spiral core. The binder can be used to form and retain the particles of activated carbon in a spiral shape. The other specific embodiment of the nucleus is a non-porous diarrhea with a porous surface for interaction with the smoke component. Alternatively or additionally, the spiral core is coated with, for example, a flavorant or an agent designed to replenish, neutralize, or otherwise interfere with the smoke group 10 200840494. The width and length of the spiral core is approximately equal The width and length of the standard tobacco smoke filter are preferred. For example, the length of a standard cigarette filter is usually between 10 and 30 mm, and the circumference is between 25 and 30 mm. The width of the spiral 5 core can be less than The standard, which can be a coaxial or multi-component encapsulation. When the spiral core is a strong and strong material, it is preferable to provide a region tightly wrapped with cellulose acetate in a coaxial manner around the outside of the spiral body. In order to make the filter feel very similar to a standard filter when in use, the length can also be adjusted, for example it can be part of a standard filter to accommodate one or more filter elements 10 at one or both ends. In order to provide For the filter of the standard, it is preferable to have a small cellulose acetate filter at the oral end of the smoking article visible to the user, so that the multi-stage filter of the present invention is cellulose acetate at the end of the user. At the end of the \ tobacco rod is a novel tobacco smoke filter. When the spiral element only forms part of the multi-component filter, it is best not to add a filter member in the spiral. The thickness of the material forming the spiral core is also It is a product variable. When the spiral is impermeable to smoke, it can be about 0.5 to 2 mm thick. When the spiral is selectively permeable to the smoke component and/or surrounding air, the thickness can be equal to 0.5 to 3 Mm. It is not necessary to have the same thickness from the entire cross section. In order to be easy to manufacture or to have a good product feel, the central portion of the spiral may be thicker than the outermost edge. Alternatively or additionally, the central axis of the helical core may be solid and form a circle having a cross-section that is a radially outward flange. In combination with the thickness of the material forming the spiral, the spacing can be adjusted to provide the draw resistance or pressure drop of the desired 200840494. The filter of the present invention can incorporate vents as is known in the art. Such pores increase the dilution of the final grass smoke and aid in inhalation through the bypass filtration path. It is most effective to add venting holes in the spiral pattern corresponding to the core of the spiral core at the position where the enclosure is not adjacent to the edge of the spiral core. The pressure drop is taken into account when deciding whether or not to use the venting holes, since the number and location of the venting holes are dependent on the shape and material of the spiral and the consideration of the filter elements used. The spiral core of the present invention can be fabricated by any suitable method. The specific production requirements for a specific 10 depend on the material and size selected and whether there is a coating on the core of the spiral. For example, cellulose acetate can be entrained and extruded out of the core during conventional filter processes. The spiral core and the location associated with the enclosure will cause the inhalation plume to have a roundabout path that is longer than the standard before reaching the user through the filter. These 15 increase the surface area and time of filtration. Therefore, the spiral core itself is a filter member. If the enclosed spiral core is only surrounded by ambient air, the inhalation smoke is not filtered as much as possible because it only needs to travel a long path before entering the user's mouth. Longer paths are used to cool the air, and some particulate matter may precipitate and stick to the core or surrounding paper. Even if the spiral core itself is composed of a filter material, and even if the spiral core is used as a small segment of the multi-segment filter, this design does not maximize the chance of filtering the smoke, but is a preferred embodiment for special use. . Therefore, in the space from the spiral body to the enclosure, an additional material can be provided to take the opportunity of the standardization of the use of the 2008 2008 4494 5 15 20 standard. For example, a randomly oriented acid-corrected fiber, i.e., can be filled with a number of tightly packed standard mouthpieces around the spiral to provide filtration and components while absorbing smoke. (4) Any acetate (for example, 2 mm) that can be added to the filter. Other options for materials around the core of the spiral include any transitional materials that are suitable for transitional smoke, and can be fragments, twists: =° The material placed around the core of the spiral can contain any of a variety of additives, such as adsorbents , absorbents, thinners, seasonings, and the like; buckets and silk plus human resources to hide in the various filter peaks. For example, a common post-active resin can be provided. Each of the conventional methods for manufacturing a smoking article can have the same size and handling as a standard filter; The mouth material can be supplied to the machine. The machine combines the invention of the invention with the tipping paper and the tipping paper into a two-bird straw stick, a packaging weaving product, but having the novel filter of the present invention in size and appearance and containing a spiral core. The enclosure can be applied to the head, or both ends can be coated with any desired additive paper. It has a scent and aroma similar to the cork pattern, as well as a pigment thinner along the outer surface, a flavorant, an aroma that improves filtration, and an inner layer of the like. Along the inner surface, for example, the tactile quality of the activated carbon particle filter, for example, a layer may be added with a layer of material to change the acetic acid, so that the filter and the mouth have cellulose with the inner diameter of the conventional nozzle. User's appeal.

The cross-sectional view of Fig. 5 illustrates an embodiment of a core 11 surrounded by a closure 12. Figs. 6A and 6B are diagrams of the circled area β. Fig. 6A shows how the edge of the spiral core 11 can be assembled in the area where it is desired to contact the enclosure 12. The edge is a deformable flange-shaped feature that flexes to allow for the inward pressure of the enclosure 12 when compressed. Figure 6B illustrates how this region adapts to compression. After the compression force is released, the edge of the spiral core u itself will return to the position with the configuration of Figure 6A. An additional benefit of the configuration type of Figures 6A and 6B is that there is a seal between the core and the enclosure, which further ensures that the smoke that can be forced through the filter passes through the helical path. Depending on the configuration and the material used for the spiral core, compressibility also improves the tactile feel for the user. For example, the material used for the core of the spiral may be elastic and provide tension during deformation to re-expand back to the original configuration after application of the tipping paper. An alternative tipping paper coating step can be performed when the point of savings is better or when having a spiral core that is not designed to be compressible. Alternatively, the spiral core is compressible. It is also swelled so that it can be restored to its original size after compression. This embodiment may be provided with rounded edges in portions of the spiral core that contact the enclosure to avoid piercing or tearing during compression or handling, please refer to Figure 6C. Another alternative is to mention the edge of the 200840494, which also reduces the feeling of tearing the crepe. Please refer to the risk that the flat part is the flat side that falls on the enclosure, and it can also improve the sealing effect and the 6D Figure.

The cutter 77 is set to The prepared filter material can be cut to the desired length. 曰, any conventional or developed alternatives can be used to make the hair, the smoke, and the mouth. For example, to make a plurality of segments as shown in Figure 8a. The continuous rod 81 in the filter and the mouth is finally divided into a plurality of individual filter units 84. A first filter segment 83, a second filter segment, and a third filter segment 85 are included. In the illustrated embodiment, the core portion of the helix 15 200840494 is mounted on the second filter segment 84. 87 Adding particles 86 to the spiral core of the second filter portion 84. The particles 86 are a filter member, an additive, or a mixture of the two. The option of the specific embodiment shown in Figure 8 is A ferry 5 small power in the spiral inner space with flavored cellulose acetate vinegar, a second nozzle small non-porous spiral, and a third ferry segment made of charcoal (such as 1 full of interference = grain empty Cavity filter, mouth or paper that forms a small section of the mouth.) For those who are familiar with this, δ 'apparently can use a variety of spring-like methods similar to those of Figure 8. Figure 〇 We expect to provide multiple distribution members In the same rod, each of which supplies a different material to the spiral core. For example, the first member supplies the first flavorant, the second member supplies the absorbent, and the third member supplies the second edible material 3. Three components to fill the various Adding to individual areas of the same/suspicious core; alternatively, they can add 0彳 country material to each spiral core one by one. When designing the spiral core to observe a specific smoke path, φ One or the other of these configurations may be preferred. For example, the beginning of the inhalation of smoke in the enclosure is observed to travel primarily along the central region of the core while the rear portion of the same stream is When traveling along the outer region of the core, less or multiple layers of filling may be preferred to provide a first material that affects the beginning of the plume and a second material that affects the back portion of the plume. The figure illustrates another embodiment in which the helical core 11 is passed through a rotating feeder 91' which simultaneously provides material 92 around the core and allows for the containment of the filling core within the enclosure 13. No. 16 200840494 The second figure shows that the cross section drawn along the line A _ A passes through the feeder 91 and fills the space around the core u. See 'Material 92 in the material and design allows a single manufacturing step to handle for some In the case of adding a mouth-reducing function to the back of the face, it is a better method. For example, the rotating head can be pressed to simultaneously fill the filter and/or the additive material in the spiral, and: the passenger is inserted between the 1A. The material can be mixed with a mixture of materials, and then added as a mixture, alternatively, one force, two, and fed in an individual manner. The latter form is preferred when the material is added or when the mixture precipitates or other problems occur. y Although Figures 7 through 1G are diagrammatic representations of a single production line for making the spiral core of the present invention, it is apparent that, for those skilled in the art, parallel steps of providing multiple units or series can be optimized for manufacturing. effectiveness. For example, the members of Fig. 9 and Fig. 1 can be assembled in two groups or in groups of 15^^, so that the number of filter cartridges produced is doubled or tripled. Production of the filter of Example 1 The activated carbon mold was formed into a spiral shape having a diameter of 6 mm. The average spacing and low porosity (i.e., low permeability eight carbons are cut to a length of about 2 to 20 meters. Several units are provided with a diameter of about 6 mm and a length of about 1 mm = standard cellulose acetate. ® bundles, and arranged in a cross-over manner with a carbon helix length 0 before the spiral/cellulose acetate bundle of this length is wrapped around a 0.5 mm thick cellulose layer. The mixture of the human feed and the adsorbent 17 200840494 is in the intra-helical space of the carbon helix. If desired, molding paper can be applied around the cellulose acetate layer as is known in the art. A length of filter material (which can be cut in the middle of a bundle of 5 cellulose acetates of about 1 mm long) can be provided to provide a plurality of filter units, each unit having a length of 30 mm and both ends of each unit They all contain a bundle of cellulose acetate of about 5 mm in length, with additives in the inner space of the spiral surrounding the carbon helix. Filters made in this way can be added to smoking objects (such as cigarette holders 10 or Cigarette holders). Water pipe m〇uthP Iece)) provides a filter material that is effective but ready to be used to allow inhalation of smoke. Different lengths and thicknesses are available depending on the intended use. For use with a slightly flat mouthpiece, the spiral core cross section can be made It is somewhat like an elliptical shape. As taught by the present invention, this can still be regarded as having a generally cylindrical shape of 15. The cigarette of Example 2 is produced by extruding a resin commonly used in tobacco smoke filters by a mold to make a diameter of about 7亳米, a tight spiral shape of 10 meters in length. The shape is fed into a machine that applies suction 20, a vacuum (for example, a suction fitting) to fill the cellulose acetate fiber around the spiral. The filled spiral is wrapped Forming paper and curing on a dry part. The cured filter is cut into a length of 60 mm and supplied to a cigarette maker. The cigarette maker uses the filter to make a cigarette in a conventional manner. Briefly 18 200840494, Place two tobacco rods at the ends of the filter, and after fixing, cut the filter in the middle. For example, add a piece of cellulose acetate to the oral end of the cigarette as needed. The spiral core unit is covered. The resulting product is a cigarette with the novel tobacco smoke filter of the present invention.
