Description of the Invention: [Technical Field to Which the Invention Is Ascribed] The present invention relates to a smoking article having a concave vent. [Prior Art] Conventionally, for example, a tobacco article comprising a tobacco rod in the form of a cylinder of tobacco or tobacco base material, which is wrapped in a roll, may have a mouthpiece unit. In its basic m-cell unit, a cylindrical element consisting of acetate tow, optionally containing features to modify the plume and mouth functions, such as recesses and voids, and chains such as: Additives. Staple fibers can be enclosed in a layer of cigarette wrap or braided material>' The (4) unit is a filter paper connection. The grass paper is attached to the outer paper layer of the filter unit. The mouth paper: 15 20 is often not porous. In general, it is desirable to dilute the smoke from the burning of ===. This can be achieved by the presence of the filter unit in the zone or perforation. When the occupant enters the _ mouth unit in the ignited cigarette, and mixes with the smoke passing through the filter and nozzle unit, it is diluted before reaching the end. The ventilation is configured to include: or - a plurality of rows of holes, which may be formed by pre-perforating the filter paper before the filter paper is applied to: 70 and before the straw, or by using a line after the assembly of the two cigarettes Work is produced in which a small hole penetrating the filter paper is burned with a beam of 1 jog = 3 201002220. The position, arrangement and number of vents are achieved - specific over-the-counter, and the workers of the industrial smoke mouth are cautiously selected ^ % ^ ii Λ η ^ Ζ ^ to pass to a specific suction experience. Because the cigarettes in the smoking department are all smoked: ...the person may not be small when sucking, but the vent hole - or more, so that the ventilation level covers the hole or Ϊ = 2, that is (in the smoking article Before the assembly, the pre-wearing method can cause the ventilation level to be more common with the period of the pass, and the amount of the towel can be transferred to the upper part of the volatile component (for example, carbon oxide). The present invention wants to solve these problems. . SUMMARY OF THE INVENTION A first aspect of the present invention is directed to a smoking article, the basin comprising a t-bar, a unit having a circumferential venting zone, and a filter for inspecting the tobacco rod and the filter unit. : The ... the external component is greater than the circumferential component of the outer diameter of the venting zone. The side is provided by the circumferential element or the element by providing or defining a recess in which the female is placed to provide the ventilation zone with a degree '^ located below the surface of the circumference of the nozzle unit : 201002220 The chance of being blocked during smoking is reduced because the surrounding raised surface makes it more difficult for the smoker's fingers or lips to directly contact the venting holes in the venting area, which is more difficult or impossible to cover by accidental and accidental coverage. More unlikely. The smoking article according to the present invention exhibits a number of important advantages over smoking articles having conventional venting systems. First, the smoking article according to the present invention allows a more consistent level of ventilation to be maintained as the flow rate (fluid gas volume) increases, so that the typical smoking volume at the consumer's smoking rate is less than the expected amount of smoke generated. Secondly, the flow upstream of the venting zone is reduced, which increases the residence time of the tobacco remaining in the tobacco rod and increases the amount of key components (such as carbon monoxide) that diffuse away from the tobacco 10 rod, which also leaves the smoke in the filter. The residence time in the tobacco rod end of the mouth is increased and the key ingredients are caused to be absorbed/reduced more by the material contained in the filter, nozzle column, such as carbon. Third, the concentration of a component such as carbon monoxide can be lowered by adding an additional region where the diffusion can occur. In some embodiments, both sides of the venting zone may be bounded by a 15 circumferential member having a larger outer diameter. The two circumferential elements can be considered to be the most capable of protecting the venting zone and thereby providing a barrier to the lips and fingers. For example, the circumferential elements can be formed by the filter paper, which is divided into two sections separated by a circumferential gap that coincides with the venting zone. This allows the invention to be practiced with additional components other than the 20 sets of conventional filter head venting articles. Therefore, in a preferred embodiment, the smoking article of the present invention comprises a tobacco rod, a filter unit having a substantially circumferential venting region, and a filter paper, wherein the boring tool of 5 201002220 defines the venting zone The A-to-circumferential void is divided in this embodiment, and the gap is such that the nozzle paper is completely cut and extended, and is also covered within the scope of the present invention; two portions on both sides of the f-gap. However, in the case of I wrapped in the packaging material, the second case is spanned. However, the area covered by the paper strip is not: the temperament of a single heart knife. For example, the above-mentioned favorable ventilation of the 6·smoke mouth may have a roll of the outer layer of the packaging material, and ^ paper. The sessile material can be porous, providing an increase in the inherent porosity of the enamel material to provide venting - or a plurality of pores (e.g., perforations). 15 The spacer is produced by wearing 'for example, before the cigarette is assembled, in the hole of the package, $ a pre-puncturing the spout material or pre-perforating the puncture bar' or after the cigarette assembly Perforation is produced using a focused laser beam. The venting t is selected and the silk packaging material can be non-porous. In this case, the action of 3 may be provided by the supply of the cigarette or the plurality of pores (e.g., perforations) in the gap between the two portions of the filter paper. This can also be achieved in seven ways, for example, in the cigarette package before the assembly of the cigarette, such as pre-perforating the filter package or pre-perforating the filter rod, or using a focus after the assembly of the smoking article. The laser beam produces a perforation. 〆 6 20 201002220 In the case of 嗜 0 &, the filter and mouth packing materials are suitable for effectively encapsulating the filter M material. In the embodiment, the filter material may be unwrapped. The level of aeration achieved may be controlled by the width of the lang, the permeability of the inherently porous material, or the degree of pre-perforation for the non-porous material, or the combination of the two and the degree of pre-perforation of the inherently porous material.

The exact width of the gap depends on a number of factors such as the length of the filter and the degree of fresh air. In the implementation of money, the gap width (four) is 2% to 75% of the length of the mouth, preferably within 5% to _ range, the first 27 coffee length filter, the mouth, the use of a minimum of 8 coffee The end-wrap section and the smallest joint of the four sides at the end of the straw (according to the ugly weight of the mouth: £) preferably give a maximum gap of 15 mm. The cigarette package is porous and the venting effect is mainly provided by the venting capacity of the cigarette package and the gap between the two parts of the filter paper, which is different from the conventional vent of the filter paper. The level of ventilation can be modified by selecting the gap width to match the venting capacity of the cigarette package, providing greater finer control over the total ventilation provided, and imparting a venting effect to the standard vents other than the filter paper. Holes can also be used to supplement the ventilation capacity, giving more flexibility to the juice in the ventilator. In addition, the venting zone can be further divided into two steps. The gap between the two parts of the filter paper includes -20107,020,022 pores (such as perforations) in the cigarette package. Another aspect of the invention is to apply additional material to either or both ends of the split filter paper. This arrangement is particularly advantageous because it deepens the recess in which the venting action occurs, making the vent more difficult to block. 5 Thus, in one embodiment, the invention provides a smoking article as described above in the broadest aspect or in a preferred aspect, having another circumferential element having a larger outer diameter, the circumferential element being divided Two portions disposed on both sides of the venting zone. In an alternative embodiment, the present invention provides a smoking article as described above in the broadest 10 aspect or a preferred aspect, having another circumferential element having a larger outer diameter from which the circumferential element The mouth end of the smoking article extends toward the venting zone. Preferably, this week the component extends partially over the venting region to overlap the venting region (partially covering the gap). Preferably, said circumferential member comprises a web of material which may be constructed of paper or fabric and is preferably an outer paper wrapper applied to the filter or mouth paper. The outer paper wrapper applied to the filter paper may extend from the mouth end of the smoking article to the venting zone. The thickness of the outer wrapper defines the barrier height/recess depth and can be selected accordingly. Preferably, the outer paper wrap has a thickness equal to or greater than 20 the thickness of the filter paper. The outer paper wrapper can have a thickness that is substantially one tenth to ten times the thickness of the filter paper. The venting zone may include one or more perforations in the filter paper pack 201002220. Still another aspect of the present invention is to use additional packaging material at either or both ends of the split filter paper such that the additional layer is superimposed on the recessed venting zone. In this case, the overlap does not adhere to the filter or filter wrap in the recess, 5 and provides additional protection against possible blockages. Additionally, the venting zone may be provided in a circumferential groove of the filter unit. A groove allows the surface diameter difference between the venting zone and the circumferential elements to be further increased to provide a deeper recess and provide more protection for the venting zone. One or more grooves may be provided, which may be provided in a longitudinal or transverse direction. In still further embodiments, the or each circumferential element can include a ridge extending above the surface of the filter paper. This provides a circumferential element that is constrained near the venting zone, which provides a look and feel that may be preferred by the occupant. 1^ The ridge may include a strip of material applied to the surface of the filter paper. For example, the material can be paper or cardboard. Alternatively, the material can be a material that is applied in a liquid form and is fast drying, such as a hot melt adhesive. Alternatively, the ridges may be formed in the filter paper and formed from the filter paper. These alternatives can be selected based on ease of production or cost, material availability, and the desired look and feel of the finished product. Embodiments using ridges can be readily adapted to provide a - boundary or barrier on both sides of the venting zone 9 201002220. Thus, both sides of the venting zone may be bounded by a ridge limit or may only be bounded by the side of the venting zone. The venting zone may include - or a plurality of perforations in the filter paper. 5 10 15 The circumference of the or each circumferential element may be as large as 2 mm from the outer circumference of the venting zone. Therefore, the venting zone is recessed below the adjacent surface of the filter unit to select the desired level of protection and the appearance of the finished smoking article. [Embodiment] In order to more clearly understand the present invention and to show how it can be implemented, the following description will be exemplified with reference to the accompanying drawings. Figures 1 and 1a show longitudinal cross-sectional views of a conventional filter head smoking article (such as a cigarette). The smoking article 1G includes a tube 12 which is wrapped in a paper bag (rolled in paper) to form a straw 15 together. - Filter unit 16 = the end of the weeding bar 15. The filter unit 16 includes a columnar filter element 18 which is shortened by a sour acid, which is wrapped in a layer of the packaging material or the filter material, and the 5 liter material can be porous. Cigarette wrap 20 maintains the shape of the filter cartridge 8 Dogs and structures are specifically used for multi-segment filters that include two or more cylindrical sections of different configurations and/or compositions that are longitudinally disposed. A 遽 = paper 22 wrapped around the filter unit W so that it is superimposed on the straw rod ^ ^, so that the filter phantom 6 secret grass stick 15 is connected at the beginning of formation = 2 unit 16 has a venting zone 2 [ The venting zone includes a venting opening 26 (see more clearly in Figure la) in the 4, . I〇 20 201002220 The aperture 26 can be formed by pre-perforating the filter paper applied to the filter unit 16 and the tobacco rod. Alternatively, the aperture 26 can be produced by focusing the laser beam burn-through = (and short-distance burning into the cigarette packet 2 and the filter element 18) in the cigarette assembly.匕 As can be seen from Figure 1, the venting zone is completely exposed, and the lips or fingers of the smoking article (4) are intended to be partial or partial. The invention is based on the fact that the surface of the venting zone is lower than the circumferential surface. In the preferred embodiment, the venting portion is applied to the clogging. The lowering of the milk portion is shown in Fig. 2 and Fig. 2a as a longitudinal view and a cross-sectional view of the first end according to the present invention. In this example, the Γ is in the second [°: filter 烟 烟 circumferential element. The cigarette pack 10 as shown in Fig. 1 includes a tobacco rod 15 by having a cigarette pack of 2 〇 I 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 The void provides a venting zone 22: - is not covered by the filter paper 22. A portion of the 22 is different, the mouth end of the pass rolling zone 24 extends to the lower boundary of the venting zone 24 / part = the filter unit swim portion, in the venting zone 24 The upstream portion, the portion is now extending between the upper positions 'to feed the material... 20 201002220 Thus, the two portions 22A, 22B of the filter paper 22 form a columnar element defining the venting zone 24. The venting zone 24 includes a porous The cigarette package material 20, or may be completely free of filter material. Therefore, the ventilated air passes through the filter as indicated by arrow A The void 28 of the paper 22 passes through the intrinsic hole 26 of the cigarette packet 20 into the filter element 18 of the 5 filter unit 16 or directly into the filter unit 16. The volatile constituents of the smoke (such as carbon monoxide) are reversed as indicated by arrow B. It diffuses out of the filter element. The cigarette package 20 must therefore be porous so that the vent is provided in a completely natural manner. This provides a unique venting arrangement in which the venting level is determined by the porosity and filter of the package 10 of the cigarette 10. The combination of the widths of the voids 28 of the paper 22 is determined by a mechanism that is different from the conventional venting method, which can be varied to provide any desired ventilation. For example, using one with 50 CorestaUnits (CU) The air-contained cigarette package and a 5-leg gap will achieve about 10% venting water. The same gap size with 200 CU cigarette package will get about 20% air permeability. 10 wake-up with 200 CU cigarette package Approximately 80% of the air permeability is obtained. The gap may have a width in the range of 1 to 20 mm, preferably 1 to 10 mm, for example. However, the invention is not limited thereto, and other 20 spaces may be used. A porous cigarette package forms a natural gas permeable barrier around the filter element 18, and because it is combined with a void in the filter paper, it provides aeration through the fine pores of the super 12 201002220 in a large area. The conventional ventilation arrangement of the discrete holes in (4) Cai. It says that it allows the gas in the smoke stream to diffuse away from the filter in the venting zone, and the mouth is single = ώ ^ it establishes a more tangible relationship between the smoke and the ventilation. The variation in the amount of smoke produced is minimized by any change in the L rate, as described below. Figures 3 and 3a show an example similar to that of Figure 2, with circumferential elements provided by a split or split mouth paper 22. . However, in this case, the secret packaging material is porous and has an additional venting opening 26 (see Fig. %), so that the ventilating air enters the filter element 18 via the external venting holes 26. In conjunction with the examples of Figures 2 and 3, a more flexible flexibility can be provided for modifying the level of ventilation such that the smoking article is disposed in the gap between the two halves of the split and the porous roll contains a venting opening in the package. The venting zone thus includes a venting opening and a roll width exposed by the void. In the above example or the example of Fig. 3, the venting holes are formed in the assembled smoking article in a convenient manner by using the in-line laser through holes. It is also possible to use pre-punched cigarette packages or unwrapped filter materials. Figures 4 and 4a show another example of smoking articles using split filter paper. The tobacco buckle 10 comprises the same components as in Figure 2 or Figure 3, so that the venting zone 24 is provided by the voids 28 and the porosity of the cigarette packet 20 and/or the additional venting holes. In addition, the kidney unit 16 has a circumferential groove 30 formed therein (where both the filter element 18 and the cigarette wrap 20 are present) at the space 28 13 201002220 between the two portions 22A, 22B of the filter paper 20. By recessing the venting zone 24 below the surface of the filter unit 16 and thereby reducing the diameter of the venting zone 24, the groove 3 〇 further enlarges the circumferential elements (filter paper portions 22A, 22B) and the venting zone 24 The outer diameter is poor. 5 Therefore, the possibility that the venting zone 24 is covered is further reduced. A smoking article according to this embodiment may also be included in the cigarette package as shown in Figure 3. In this case, the roll may be porous or non-porous. The circumferential groove or recess 3G can have any depth because any reduction in the diameter of the venting zone enhances its ability to resist clogging. The depth of the example is in the range of no more than 3 10 coffee, preferably in the range of 1 to 2 coffee. The grooves 30 may be formed on the filter rod by a warming former (scented in a pre-process) or formed on the nozzle after production, or may be formed by a known standard trenching method. Figures 5 and 5a show another example of smoking articles using split filter paper. Tobacco|0 includes the same components as Figure 2, so the venting zone 24 is provided by the porosity and the porosity of the 15 cigarette packets. In addition, the depth of the recess (24) has been further increased by the addition of another layer of mouth paper at the mouth end (32A) and/or at the straw end (32B). Figures 6 and 6a show another example of smoking articles using split filter paper. The smoking article comprises the same components as in Figure 5, so that the venting zone 24 is provided by the porosity and the porosity of the package. In addition, the additional wrap material added to the mouth end (32) extends over the recess but does not adhere to the recess to provide further protection against clogging of the venting portion. In an alternate embodiment (not shown), the additional wrap material may be at the end of the wand and (or instead) 14 201002220 extending over the mouth end to the recess. Embodiments of the present invention comprising a split filter paper can be manufactured only with minor modifications to the process of conventional smoking articles. The filter paper can be applied by conventional means using this procedure, either in a separate stage for the two parts, or at the same time using two rolls of appropriately sized filter paper, which corresponds to the desired gap on the single dispenser. The distances of the widths are separated. As previously mentioned, the venting holes of the cigarette package (if any of the cigarette packages are used) may be formed by prior perforation or on the line after the smoking article has been fully or partially assembled. Figure 7 shows an example of a smoking article in accordance with another embodiment. Similarly, the tobacco product 10 includes a tobacco rod 15 and is coupled to a filter unit 16 by a filter paper 22 having a vent hole 26 (pre-perforated or formed by a thunder ray) Ventilation zone 24. A cigarette packet can be included in the filter unit 16. The smoking article 10 is different from the conventional smoking article, as shown in Fig. 1, and further includes two circumferential ridges 34 disposed on the filter paper 22 around the filter unit 16. A ridge portion 34A is formed on the downstream side of the venting region 24, and a ridge portion 34B is provided on the upstream side of the venting region 24. The ridge 34 provides a circumferential element with a diameter greater than the venting zone 24 that prevents the venting zone 24 from becoming clogged. The upstream ridge 34B provides a barrier or boundary that guides or guides the smoker's fingers further upstream of the venting zone 24 such that the venting holes are not blocked. The downstream ridge 34A provides a barrier that prevents the smoker from placing the filter unit 16 into the mouth to a level that blocks the vent 26 due to the lips. Again, the ridges 34 have a function of 15 201002220 which makes it more difficult to intentionally cover the vents 26 with smoke on the venting area because the ridges 34 are close enough to each other that the fingers remain a distance above their lower holes. The ridges 34 may be spaced apart by a distance in the range of 2 to 10 mm, but 5 the spacing is selected in part with reference to the width of the venting zone 24. Further, the height of the ridge portion 34 may be in the range of 0.2 to 2 faces, for example, 1 leg. The two ridges may be of the same height or may provide ridges of different heights. The ridges may have a width in the range of X to Ymm, and each ridge may have a different width. Sizes other than the above examples may also be employed. In the example of Figure 7, the ridge 34 includes a cardboard or paper strip that is applied to the filter paper and secured to the spot by an adhesive. The thickness of the cardboard or paper determines the height of the ridges 34, but more than one layer of cardboard or paper may be applied to increase the thickness. These strips can be applied to the filter paper after assembly of the smoking article, for example by means of a device that wraps the strip of material with the pre-coated adhesive on the filter unit. Alternatively, the ridge material may be adhered to the filter paper before the filter paper is used to assemble the smoking article, for example by providing the continuous material before the filter paper material is formed into a roll for supply to the assembly device. The strip is applied in the manner of a filter paper material. Fig. 8 shows an example similar to Fig. 7, but in this case the circumferential element package 20 includes ridges 36A, 36B of a fast drying material such as a hot melt adhesive. This material is applied to the filter paper in the form of a thin bead liquid, which is hardened and bonded to the filter paper. Each ridge may be applied separately, such as from a nozzle of two 16 201002220 on the production line, or may be applied simultaneously with a pair of appropriately spaced nozzles or their devices. The ridges can be added to the filter paper in the assembly of the smoking article. Alternatively, a large ridge may be applied along the length of the mouthpiece material before the filter paper material is formed into a roll.卩 material. The ridge material may be applied in a continuous bead shape; ",' to form an uninterrupted ridge. Alternatively, the ridges may be formed from a series of adjacent points or lines of ridge material. Another example of an embodiment utilizing a ridge to protect the venting zone is illustrated. In this example, the ridges 38A, 38B are integrally formed by the filter and the mouth paper. 1 〇 7 is not a separate component applied to the filter or the mouth paper. The filter paper has a pair of snake-shaped folds j: pleats: or other suitable folds, which are produced in the paper before the filter paper is wrapped around the filter S* unit and the private straw to form a complete cigarette. . These fingering areas protrude from the surface of the mouth paper to provide a ridge. Individual care papers can be discounted prior to use, but a more practical and effective way is to roll the rolls into 15 rolls of continuous lengths of towels, and the rolls are wound into rolls for supply to the assembly. The filter paper can be pre-perforated, in this case forming - or a plurality of folds on each side of the perforated area. Alternatively, the venting holes may be created by lightning rays after the filter paper has been applied. The examples of Figures 7, 8 and 9 each include two separate ridges 20 such that the venting zone is bounded on both sides. However, a single ridge may be used as long as it provides the desired level of protection for the venting zone. The single ridge can be positioned upstream of the venting zone to prevent clogging of the finger or positioned downstream of the venting zone to prevent clogging by mouth. 17 201002220 Figure ίο - shows an example of a single-ridged downstream of the venting zone, and the ridge is formed by a strip of cardboard or paper tape as shown in Figure 7 (4) . Example 1 A scented end having a cigarette wrap-wrapped filter and a split filter paper wrap (10-gauge width) as shown in Figs. 2 and 2a was prepared. A standard aeration product with a vent added by OML was prepared as a control. The fragrance of the present invention and the control have physical data / 10 specifications as shown in Table 1.
