Description

吸煙物品Smoking items

本發明係有關於一種吸煙物品，包含一可吸煙桿及一雙重濾件，其能從該濾件末端提供一改良的外觀及一改良的過濾效果。The present invention relates to a smoking article comprising a smokable rod and a dual filter member that provides an improved appearance and an improved filtration effect from the end of the filter member.

US 4 256 122A專利揭露一種香煙，包含單一濾件含有縱向凹槽在其側邊區域，其會由該嘴側濾件端延伸，且在此端係可看見的。該煙嘴，其會將該濾件連接於煙草桿並覆蓋該等凹槽，在該等凹槽的區域中係設有通氣孔等，因此該等凹槽是通氣的。US 4 256 122 A discloses a cigarette comprising a single filter element having a longitudinal groove in its side region which is extended by the mouth side filter end and is visible at this end. The mouthpiece will connect the filter member to the tobacco rod and cover the grooves, and vent holes or the like are provided in the regions of the grooves, so that the grooves are ventilated.

一類似的設計係可由US 4 708 150A專利得知。在該案中，該濾件之添加的通氣孔係被設在該等凹槽的上游處。A similar design is known from the US 4 708 150A patent. In this case, the added venting holes of the filter element are provided upstream of the grooves.

DE 34 03 281A專利揭露一種香煙包含一雙重濾件。該嘴側濾件段包含一纖維素乙酸酯濾芯被一設有縱向延伸的溝紋之非多孔包捲物包圍。該桿側濾件段包含纖維素乙酸酯和活性碳作為一吸附劑。該二濾件段係以一共同的連接包捲物互相連接。一非多孔煙嘴紙會形成最外層，並將該雙重濾件附接於該煙草桿。由該等溝紋形成的凹槽係被多個通氣孔來通氣。DE 34 03 281 A discloses a cigarette comprising a double filter. The mouth side filter section comprises a cellulose acetate filter element surrounded by a non-porous wrap having longitudinally extending grooves. The rod side filter section comprises cellulose acetate and activated carbon as an adsorbent. The two filter segments are interconnected by a common connecting wrap. A non-porous mouthpiece paper will form the outermost layer and attach the dual filter to the tobacco rod. The grooves formed by the grooves are vented by a plurality of vent holes.

在所該該等案例中，被形成於該嘴側濾件區域之側邊區處的凹槽作用如通道，會透過該等通氣孔來與環境空氣導通，因此稀釋該煙草之煙的空氣會直接進入該吸煙者的口內。此可能會引致一較不愉快的印象。In such cases, the grooves formed at the side regions of the mouth-side filter region act as channels through which the ambient air is conducted, thereby diluting the air of the tobacco smoke. Directly into the mouth of the smoker. This may lead to a less pleasant impression.

而且，單一濾件係已知包含多個凹槽排列在該濾件的側邊區域。該等凹槽會由該濾件的嘴側端露現而縱向地延伸，但並不延伸至該濾件的另一端。該等凹槽係凹凸於一內紙卷中。一附加的外柱卷可為標準的或多孔的。此等濾件係由Essentra Filter Products公司以商標名稱"Combined Performance Superior^TM Filter"行銷。另一種由Essentra公司以商標名稱"Combined Performance Superior^TM Dual Filter"來行銷的產品係為一雙重濾件，其包含前述的單一濾件加上一桿側的濾件段，含有纖維素乙酸酯和活性碳作為一吸附劑。在該二例中，通氣孔係未被提供。Moreover, a single filter element is known to comprise a plurality of grooves arranged in the side regions of the filter element. The grooves may extend longitudinally from the mouth side end of the filter member but do not extend to the other end of the filter member. The grooves are embossed in an inner roll.

Another product marketed by the company Essentra under the trade name "Combined Performance Superior ^TM Dual Filter" is a dual filter element comprising the aforementioned single filter element plus a rod side filter section containing cellulose acetate And activated carbon as an adsorbent. In both cases, vents were not provided.

EP 2 265 137 B專利揭露一種複合材料係由纖維素乙酸酯和沈澱的二氧化矽所形成，其可被例如用於液體或氣體的過濾，或用於香煙濾件中。The EP 2 265 137 B patent discloses a composite material formed from cellulose acetate and precipitated cerium oxide, which can be used, for example, for filtration of liquids or gases, or for use in cigarette filters.

本發明的目的係提供一種吸煙物品，其會結合一在嘴側末端的特殊外觀及一高過濾度和氣相減少的性能，而不會呈現前述之不愉快的空氣稀釋效果。SUMMARY OF THE INVENTION It is an object of the present invention to provide a smoking article which combines a special appearance at the mouth side end with a high degree of filtration and gas phase reduction without exhibiting the aforementioned unpleasant air dilution effect.

此目的係可被一具有請求項1之特徴的吸煙物品達成。本發明的有利態様可由依附的請求項得知。This object can be achieved by a smoking article having the characteristics of claim 1. Advantages of the invention are known from the dependent claims.

依據本發明的吸煙物品包含一可吸煙桿(例如一煙草桿被以香煙紙包捲)及一雙重濾件。該濾件包含一桿側濾件段，其含有一過濾材料與一吸附劑，及一嘴側濾件段。該嘴側濾件段會由一嘴側第一端延伸至一第二端，其中有一第一側邊區域起始於該第一端並延伸至大約中間圓周線，而一第二側邊區域會由該線延伸至該嘴側濾件段的第二端。該嘴側濾件段包含一過濾材料，例如纖維素乙酸酯。多個凹槽(通道)係列設在該第一側邊區域，即，只在該第一側邊區域。此等凹槽會由該嘴側濾件段的第一端延伸，並大致縱向地直行，即大致平行於該吸煙物品的縱軸。多個通氣孔係被設在該第二側邊區域，且該等凹槽並不被任何設在該第一側邊區域的通氣孔來通氣。較好是，該雙重濾件除了該等設在該嘴側濾件段之第二側邊區域者以外並不包含通氣孔。A smoking article in accordance with the present invention comprises a smokable rod (e.g., a tobacco rod is wrapped in cigarette paper) and a dual filter. The filter element comprises a rod side filter section comprising a filter material and an adsorbent, and a mouth side filter section. The mouth side filter section extends from a mouth side first end to a second end, wherein a first side edge region begins at the first end and extends to approximately the middle circumferential line, and a second side edge region It will extend from the line to the second end of the mouth side filter segment. The mouth side filter section comprises a filter material such as cellulose acetate. A plurality of grooves (channels) are provided in the first side region, that is, only in the first side region. The grooves will extend from the first end of the mouth-side filter segment and will travel generally longitudinally, i.e., generally parallel to the longitudinal axis of the smoking article. A plurality of vent holes are provided in the second side region, and the grooves are not ventilated by any vent holes provided in the first side region. Preferably, the dual filter element does not include a vent hole other than the second side region of the mouth side filter element segment.

因該等凹槽起始於該嘴側濾件段的第一端，即吸煙物品的嘴側端，故它們在此端是可見的，並會對該吸煙物品提供一特殊的外觀。該等凹槽並非一空氣通氣系統的一部份，因為它們不會被通氣孔通氣。因此，依據本發明的吸煙物品之通氣程度在使用時不會被該嘴側濾件段的壓擠(例如被該吸煙者的唇)所影響，其可能會阻塞該等凹槽形成的通道。Since the grooves start at the first end of the mouth-side filter segment, i.e., the mouth-side end of the smoking article, they are visible at this end and provide a special appearance to the smoking article. These grooves are not part of an air venting system because they are not vented by the vents. Thus, the degree of aeration of the smoking article according to the present invention is not affected by the compression of the mouth-side filter segment (e.g., by the smoker's lips) during use, which may block the passage formed by the grooves.

在該桿側濾件段中未設通氣孔具有另一有利的效果。於此情況下，因通氣空氣被抽經該裝有吸附劑的濾件段會引生一增加的空氣流，其可能會在該通氣區域的下游區域中減低該吸附劑的效率，此將不會發生。The absence of a vent in the rod side filter section has another advantageous effect. In this case, the ventilating air is drawn through the sorbent-loaded filter section to induce an increased air flow which may reduce the efficiency of the sorbent in the downstream region of the venting zone, which will not will happen.

在本發明的較佳實施例中，該嘴側濾件段包含一內包捲物，其在該第一側邊區域中會界定該等凹槽，而在該第二側邊區域中是平坦的。該等內包捲物在該第一側邊區域中可為有溝紋的，而以溝紋形成凸脊和凹谷等，其中該等凹谷係位在該嘴側濾件段之過濾材料的凹部中，故會界定出該等凹槽。又，該嘴側濾件段可包含另一包捲物(以下稱為柱包物)，其會疊覆該內包捲物，且係包捲成大致呈圓筒形。以此方式，該等溝紋和該柱包物會形成通道。在該第二側邊區域中，該柱包物會緊抵該內包捲物，大致覆蓋於整個第二側邊區域上。該柱包物可被膠合於該內包捲物，其中較好該等通道實質上係保持沒有膠劑。In a preferred embodiment of the invention, the mouth side filter section includes an inner wrap that defines the grooves in the first side region and flat in the second side region of. The inner wraps may be grooved in the first side edge region, and ridges and valleys may be formed by grooves, wherein the concave valleys are in the filter material of the mouth side filter segment. The recesses are defined in the recesses. Further, the mouth side filter section may comprise another wrapper (hereinafter referred to as a post wrap) which overlies the inner wrap and is wrapped in a generally cylindrical shape. In this way, the grooves and the column pack form a channel. In the second side region, the column pack will abut the inner wrap substantially over the entire second side region. The column wrap can be glued to the inner wrap, wherein preferably the channels are substantially free of glue.

該內包捲物可為多孔的。於此情況下，被經由該等通氣孔進入該嘴側濾件段之空氣稀釋的主煙流會被抽經該嘴側濾件段的過濾材料，但是亦可穿過該多孔的內包捲物進入該等通道，而在其流到下游之前會被該內包捲物的材料(例如紙)過濾，故會大致上無阻且不會再稀釋地，穿過該等凹槽或通道而至該吸煙者口中。The inner wrap may be porous. In this case, the air-diluted main plume that enters the mouth-side filter section via the vents is drawn through the filter material of the mouth-side filter section, but may also pass through the porous inner wrap. The objects enter the channels and are filtered by the material (eg paper) of the inner wrap before they flow downstream, so they are substantially unobstructed and do not dilute, passing through the grooves or channels The smoker is in the mouth.

該桿側濾件段和該嘴側濾件段能被以一連接包捲物來互相連接。原理上，前述的柱包物能被用作該連接包捲物，但較好是有另一包捲物會被使用，其當該二濾件段被端對端地放置時係繞著該嘴側濾件段的柱包物和該桿側濾件段的側面捲繞。於此情況下，該桿側濾件段的過濾材料及該吸附劑亦可被包捲在一獨立的柱包物中，其會構成該桿側濾件段的側面，並且被該連接包捲物包覆。The rod side filter section and the mouth side filter section can be interconnected by a connecting wrap. In principle, the aforementioned package can be used as the connection wrap, but preferably another wrap is used, which is wound when the two filter segments are placed end to end. The column pack of the mouth side filter section and the side of the rod side filter section are wound. In this case, the filter material of the rod side filter section and the adsorbent may also be wrapped in a separate column package, which will constitute the side of the rod side filter section and be wrapped by the connection. Material coating.

最後，作為一最外的包捲物，一煙嘴可被用來將該雙重垂濾件連接於該可抽煙桿。通常，該煙嘴係由紙製成，但其它的材料亦可被想出。Finally, as an outermost wrap, a mouthpiece can be used to attach the double drip filter to the smokable rod. Usually, the mouthpiece is made of paper, but other materials can also be conceived.

在本發明的較佳實施例中，該連接包捲物及／或該煙嘴係非多孔的，即用於該連接包捲物及／或該煙嘴的材料係本質上非多孔的或只有一非常低的孔隙率。在此情況下，當使用時環境空氣實際上只能經由該等通氣孔進入該雙重濾件。若該連接包捲物及／或該煙嘴係非多孔的，則任何柱包物的孔隙率之選擇(例如高或非常低)將不會有一特別的影響。In a preferred embodiment of the invention, the connecting wrap and/or the mouthpiece is non-porous, ie the material used for the connecting wrap and/or the mouthpiece is essentially non-porous or only one very Low porosity. In this case, ambient air can only actually enter the dual filter element via the vents when in use. If the joint wrap and/or the mouthpiece is non-porous, the choice of porosity (e.g., high or very low) of any of the column packs will not have a particular effect.

該濾件通氣率可為例如至少20%或至少40%。較好是，該等通氣孔係為雷射打孔的。雷射打孔的通氣孔可在一香煙製造者的生產線上，於製造該等吸煙物品時，在一雙重濾件已在一組合機上被附接於一各別的煙草桿之後，且在施加一煙嘴之後，來被製備。一般而言，該等雷射束會貫穿該煙嘴和該連接包捲物，以及該嘴側濾件段的該柱包物和該內包捲物。The filter member aeration rate can be, for example, at least 20% or at least 40%. Preferably, the vents are laser perforated. The laser perforated vents may be on a cigarette manufacturer's production line, after the manufacture of the smoking articles, after a dual filter has been attached to a respective tobacco rod on a combination machine, and After a cigarette holder is applied, it is prepared. In general, the laser beam will extend through the mouthpiece and the attachment wrap, as well as the column wrap and the inner wrap of the mouth side filter section.

在本發明的較佳實施例中，於該桿側濾件段中的吸附劑係為一種含有二氧化矽的複合材料，例如被製成含有一纖維素乙酸酯／二氧化矽基質的多孔顆粒。此等材料及其製造方法可由EP 2 265 137 B專利得知。二氧化矽具有良好的吸附性質，且該等顆粒的纖維素乙酸酯會改良該桿側濾件段之過濾材料(例如纖維素乙酸酯)內的顆粒之黏附性。In a preferred embodiment of the invention, the adsorbent in the rod side filter section is a composite material comprising cerium oxide, for example, made into a porous matrix comprising a cellulose acetate/ceria substrate. Particles. Such materials and methods for their manufacture are known from the patent EP 2 265 137 B. Cerium oxide has good adsorption properties, and the cellulose acetate of the particles improves the adhesion of particles in the filter material (e.g., cellulose acetate) of the rod side filter section.

圖1以一三維局部示意圖示出一吸煙物品(標示為1)之一實施例。Figure 1 shows an embodiment of a smoking article (labeled 1) in a three-dimensional partial schematic view.

該吸煙物品1包含一煙草桿2以香煙紙包捲，有一雙重濾件4附接於它。除了煙草以外的其它可抽煙材料亦可想知。該雙重濾件4包含一桿側濾件段6及一嘴側濾件段8。The smoking article 1 comprises a tobacco rod 2 wrapped in cigarette paper with a double filter element 4 attached thereto. Other flammable materials besides tobacco can be imagined. The dual filter element 4 comprises a rod side filter section 6 and a mouth side filter section 8.

該桿側濾件段6包含一過濾材料及一吸附劑，並被以一個別的柱包物包捲，其未被詳細示於圖1中。在該實施例中，纖維素乙酸酯係被用作該過濾材料。該吸附劑是二氧化矽包含在多孔顆粒中，其亦含有纖維素乙酸酯。該等顆粒可由例如EP 2 265 137 B1專利得知。The rod side filter section 6 comprises a filter material and an adsorbent and is wrapped in a further column pack, which is not shown in detail in FIG. In this embodiment, cellulose acetate is used as the filter material. The adsorbent is cerium oxide contained in porous particles, which also contains cellulose acetate. Such particles are known, for example, from the EP 2 265 137 B1 patent.

該嘴側濾件段8包含一過濾材料10(例如纖維素乙酸酯)，並由係為該雙重濾件4的嘴側端之一第一端12延伸至一第二端13。圖1示出一中間圓周線14，為一虛線，其係被畫出來將該嘴側濾件段8的側邊區域分成一第一側邊區域16(由該第一端12延伸至該中間圓周線14)及一第二側邊區域17(由該中間圓周線14延伸至該第二端13)。The mouth side filter section 8 comprises a filter material 10 (e.g., cellulose acetate) and extends from a first end 12 of the mouth side end of the dual filter element 4 to a second end 13. Figure 1 shows an intermediate circumferential line 14, which is a dashed line, which is drawn to divide the side region of the mouth-side filter segment 8 into a first side region 16 (from the first end 12 to the middle) A circumferential line 14) and a second side region 17 (extending from the intermediate circumferential line 14 to the second end 13).

在該第一側邊區域16處，係設多數個凹部20，其會由該第一端12延伸並大致縱向地直行，即平行於該吸煙物品的縱軸。但是，在該過濾材料10中的凹部20並不通過該中間圓周線14，因此它們係被限制於該第一側邊區域16內。一內包捲物22係繞該嘴側濾件段8包捲。在該第一側邊區域16中，該內包捲物22係具有溝紋的，而以溝紋形成凹谷24和凸脊26等，其中該等凹谷24對應於該等凹部20，而該等凸脊26保持在該過濾材料10之原來表面的水平處，其係為該大致呈圓筒狀的第二側邊區域17之層面。於此實施例中，該內包捲物22係由一多孔紙製成。At the first side edge region 16, a plurality of recesses 20 are provided which extend from the first end 12 and run generally longitudinally, i.e. parallel to the longitudinal axis of the smoking article. However, the recesses 20 in the filter material 10 do not pass through the intermediate circumferential line 14, so they are confined within the first side edge region 16. An inner wrap 22 is wrapped around the mouth side filter section 8. In the first side region 16, the inner wrap 22 is grooved, and the valleys 24 and the ridges 26 and the like are formed by grooves, wherein the valleys 24 correspond to the recesses 20, and The ridges 26 are held at the level of the original surface of the filter material 10 as a layer of the substantially cylindrical second side region 17. In this embodiment, the inner wrap 22 is made of a porous paper.

該嘴側濾件段8包含另一包捲物28(柱包物)。其會疊覆該內包捲物22，且係包捲呈大致為圓筒形。於本實施例中，該柱包物28係由一多孔紙製成，而在該等凸脊26的區域和該第二側邊區域17膠合於該內包捲物22。該膠劑一般不會進入該等凹谷24內。以此方式，該內包捲物22的凹谷24等在該等凹部20中會與該柱包物28的重疊部份組合而形成多個通道(凹槽)延伸於該嘴側濾件段8的第一側邊區域16處。The mouth side filter section 8 contains another wrap 28 (column pack). It overlies the inner wrap 22 and the wrap is generally cylindrical. In the present embodiment, the column pack 28 is made of a porous paper, and the region of the ridges 26 and the second side region 17 are glued to the inner wrap 22. The glue generally does not enter the valleys 24. In this way, the valleys 24 and the like of the inner wrap 22 are combined with the overlapping portions of the column pack 28 in the recesses 20 to form a plurality of channels (grooves) extending from the mouth side filter section. The first side edge region 16 of 8.

在本實施例中，該桿側濾件段6包含其本身的柱包物(未分開地示於圖1中)。該嘴側濾件段8和該桿側濾件段6係以一連接包捲物(未示於圖1中)互相連接，其可方便該雙重濾件4的組合。該後者的柱包物及該連接包捲物可由多孔紙或非多孔紙製成。In the present embodiment, the rod side filter section 6 contains its own column packing (not shown separately in Figure 1). The mouth side filter section 8 and the rod side filter section 6 are interconnected by a joint wrap (not shown in Fig. 1) which facilitates the combination of the dual filter element 4. The latter column package and the connection wrap may be made of porous paper or non-porous paper.

該雙重濾件4係以一煙嘴30連接於該煙草桿2，其係膠合於該雙重濾件4和該煙草桿2之濾件側末端區域的外表面上。在本實施例中，該煙嘴30係由一非多孔性材料或一具有低或非常低之孔隙率的材料製成，例如一紙材料。The double filter member 4 is attached to the tobacco rod 2 by a mouthpiece 30 which is glued to the outer surface of the filter element side end region of the double filter member 4 and the tobacco rod 2. In the present embodiment, the mouthpiece 30 is made of a non-porous material or a material having a low or very low porosity, such as a paper material.

多個通氣孔32係被設在該嘴側濾件段8的第二側邊區域17處，並只在此區域中，因此由該等凹部20界定的通道或凹槽並不會通氣。在圖1中，該等通氣孔32係排列在一圓周線上。通氣孔的其它圖案亦可被想知。該等通氣孔32能藉一線上雷射打孔技術來製備，並延伸穿過全部各層的包捲物，即，穿過該煙嘴30，穿過未示於圖1中的連接包捲物，穿過該柱包物28，及穿過該內包捲物22等。以此方式，該通氣空氣會直接進入該過濾材料10中。A plurality of venting holes 32 are provided at the second side edge region 17 of the mouth side filter element section 8 and only in this area, so that the channels or grooves defined by the recesses 20 are not vented. In Figure 1, the vents 32 are arranged on a circumferential line. Other patterns of vents can also be imagined. The vents 32 can be prepared by a line of laser puncturing techniques and extend through the entire stack of wraps, i.e., through the mouthpiece 30, through a wrapper not shown in FIG. Pass through the column pack 28, and through the inner wrap 22 and the like. In this way, the venting air will enter the filter material 10 directly.

當該吸煙材料1被使用時，被該通氣空氣稀釋的主煙流可不僅流經穿過該過濾材料10進入該使用者口中，且亦會由該過濾材料10穿過該多孔內包捲物22，並經由該等凹部20所界定的通道等來進入。When the smoking material 1 is used, the main smoke stream diluted by the venting air may not only flow through the filter material 10 into the user mouth, but also through the porous material wrapping material through the filter material 10. 22, and enters through a channel or the like defined by the recesses 20.
