[Embodiment] Fig. 1 shows a cross-sectional side view of a smoking article having a detachable cover in accordance with an embodiment of the present invention. The smoking article 1 is a filter-tipped and conventional structure having a tobacco rod 12 coupled to the filter unit 14 via a tip coated paper (not shown). Further, the smoking article 1 according to the embodiment also includes a protective cover 16. The cover 16 is attached to the end of the filter of the smoking article to cover the end surface of the filter unit 14, and extends along the side of the smoking article 1 to cover at least the side portion of the eliminator unit 14. The lid 16 is secured to the side of the smoking article 10 via an adhesive 18 disposed between the side of the smoking article 10 and the inner surface of the lid 16. In the present example, the adhesive 18 is disposed adjacent to the edge of the cover 16 remote from the end of the filter unit 14, and extends circumferentially around the smoking pop. According to this embodiment, the cover 16 has a circumference I of 2009 200913 weak fo, such as a line of perforations or a thin material, which is at the end of the adhesive 18 and the filter unit 14. There is 'and is substantially adjacent to the binder 18. The lid 16 is made of a portion of a thin elastic sheet that is wrapped around the filter, H unit end of the smoking article 1G such that a portion of the sheet extends beyond or protrudes beyond the end of the filter unit. The protruding portion 22 is folded to cover the end of the filter unit. Therefore, the protruding portion 22 is preferably slightly longer than the radius of the smoking article 10 15 ❿ 20 product 10 so that the folded portion can completely cover the end of the filter unit to better protect it from contamination. The adhesive 18 secures the sheet to the side of the smoking article 10. Figure 2 shows a perspective view of a smoking article having a detachable cover 16 at a suitable location. Although the cover 16 is shaded, it differs only from the conventional wrapping paper ί4 of smoking articles. In practice, the cover 16 can be made of the same type and/or color, or a different color, or a transparent sheet as the cigarette paper 24, or its decorative pattern or trademark, or an indication that the cover 16 can be detachably printed. In the present embodiment, 'adhesive 18 is a permanent adhesive in which a substantially permanent bond is formed between cover 35 and smoking article 1〇. & Disassembly cover 16 is ready to use smoking article 10, the consumer gripping the outer surface of cover 16 and pulling in a direction substantially parallel to the longitudinal axis of smoking article 10. The tension is applied to cause the circumference of the cover 16i4 and the weak portion 20 to be divided into two parts. The end of the cover filter unit is not attached to the smoking article 1 and can slide away from the end of the smoking article to the end surface of the Monroe and at least part of the side of the filter unit 14. Alternatively, the cover material can be opened by pulling 2 in the tangential direction so that it can be torn and divided along the line of the weak point 20. Keep away from the filter unit 9 200932131 The 4th knife of the last known is attached to the smoking item lG, because the * keeps positioning, like the molding of the material surrounding the smoking object απ. Thus, in the present embodiment, the cover can be partially removed.

• J +, Figure 3 shows no cover ^ 16 part of the smoking article 10 after the end of the section of the cut-off 5 from the sneak peek 4 device 6 is completely exposed so that the smoking substance is ready for suction, while the cover 16 is left The panel 26 remains attached to the side of the smoking article. Figure 4 shows a perspective view of the end of the smoking article 1 after the cover 16 has been partially removed. The lid 16 should be configured relative to the last position and size of the remaining inlay of the material after partial removal of the lid 16. These parameters are determined by the distance the cover is taken from the edge of the cover 16 along the entire length of the side of the smoking article and the line of weakness. If the fillet 26 is located above the tobacco rod 12, it should be made of a flammable material that does not interfere with the burning of the tobacco rod during smoking. If the fillet 26 is positioned above the filter leader 14, the radial thickness and position 15 should be considered and will not cause discomfort or discomfort when the filter unit is placed in the mouth of the smoker. In either case, it is preferred that the panels are not overlaid on the venting of the smoking article or the tip of the paper to cause clogging, as it will unnecessarily reduce the ventilation of the smoking article 10. Figure 5 shows a plan view of a portion 20 of a sheet 28 suitable for making a cover 16 in accordance with the embodiment of Figures 1 through 4. The sheet 28 is substantially rectangular in shape having a width sufficient for the sheet to completely surround the circumference of the smoking article 10 and possibly having overlapping edges. The long product of the sheet 28 comprises a length k' of the portion of the crucible that will be folded over the end surface of the filter unit, which must exceed the radius of the smoking article, and the length of the portion B that will be used to wrap the outer surface of the smoking article. . The length 200932131 B determines the distance that the lid 16 extends along the smoking article and is sufficient to completely or partially cover the side of the filter II unit, as discussed in the front-segment, which also has a strip of material that will be retained after the disassembly of the forceps portion. The desired location. The age of the adhesive 18 is applied across the width 5 of the sheet 28 along the edge of the portion b, which will be remote from the end of the filter unit. The line of weakness 20 extends across the width of sheet 28 and is adjacent to adhesive 18. The line of substitution is the line of weakness 20 which can be spaced apart from the adhesive 18. In this example, the line of weakness 20 is a straight line. However, it may be a zig-zag or a non-straight line which will provide a decorative edge that retains the panel of material surrounding the smoking article after the cover portion has been removed. The alternative is that the adhesive can be applied to the exterior surface of the smoking article rather than to the sheet. In either case) after application of the adhesive, the sheet tightly wraps around the smoking article to cover the side of the cover & <a small portion of the filter unit and form a projection of the sheet 15 . The protruding portion is then folded to surround the end surface of the filter unit. You can use any of the folding styles, such as a series of overlaps ® creases, or "envelop" creases that contain four creases and in which the creases are continuously formed. Either method can be used to apply the adhesive, apply the sheet to the smoking article 2〇 and wrap it around the smoking material&apos; and then fold the protruding portion. Various methods and techniques for wrapping the foldable paper around the smoking article and folding the protruding portion of the paper to close the tobacco end of the smoking article are filed on November 14, 2006, pending application of GB 0622687.2 And GB 0703785.6, filed on February 27, 2007 (both titled "200932131 Smoking Articles and Methods and Devices for Smoking Articles with Closed Ends"). The methods and techniques are the same. Suitable for applying and folding a sheet to the end of the filter of the smoking article to form a cover according to the invention. For the cover manufactured according to the first embodiment, it is possible to use a suitable for thinning and bending by winding and folding Any sheet for the necessary processing. Examples include falling, paper, cardboard, plastic materials, and sheets incorporating the materials. Figure 6 shows a perspective view of the end of a smoking article configured to provide a detachable cover in accordance with another embodiment. 16 is formed in the same manner as the lid of the embodiment of Figures 1 and 2, by wrapping the sheet around the end of the filter of the smoking article 10 and folding it over. Portion 22 covers the end surface of the filter unit. However, in this example, there is no line of weakness around the cover 16. Instead, the cover 16 is allowed to be removed, wherein the adhesive is a non-permanent adhesive that is not covered by the cover. 16 creates a permanent link with the smoking item lp, but allows the two

.J points can be opened and separated. Thus, the lid 16 can be completely removed from the smoking article 16 and the filter unit exposed prior to smoking the smoking article 10. Figure 7 shows a perspective view of the smoking article 10 of Figure 6 after the cover 16 has been removed, showing that the cover is not entirely visible in the drawing and the filter unit 14 is completely exposed. The lid 16 can be detached from the smoking article by being pulled apart in the longitudinal direction, or can be peeled off by opening the lid material surrounding the smoking article. A protruding tab can be provided to facilitate removal of the cover, which can be gripped to open or open the cover. Figure 8 shows a portion of a sheet suitable for making a lid according to the embodiment of Figure 6: a plan view of a 12, 2009, 2009, 13, 10, 20, 20 material. As shown in the sheet of Figure 5, the sheet 28 has a strip of adhesive applied along an edge and includes a portion of the wrapped article and a portion of the file that will protrude and fold over the end of the filter unit. However, the sheet does not have a line of weakness and the adhesive 18 is of a non-permanent type. At the same time, the projection 30 extends along the edge of the sheet 28. When the sheet 28 is formed in the lid, the portion 30 is disposed on the outer surface of the lid and can be gripped, held, and used to pull the lid away from the smoking article: The cams can be an option and can be of different shape and/or position as desired. After it is removed, the sub-possible projections can also be provided in the only partially detachable tweezers, as shown in Figures 1 and 2. Design restrictions. Therefore, it is determined by the degree of protection of the side of the smoking article and the degree of protection of the side of the smoking article. The continuous continuous fillet of the examples of Figures 5 and 8 can be replaced by a broken fillet or a line of viscous ==: instead of 'distribution' with a dispersion spaced along its edges: Medium, applying a bond of the film ΑΑ9δΑΑ Yang&lt;-1 solid knife administration (he can permanently remove the permanent adhesive::::. This configuration will make the cover easier to remove for non-mixing: unloading = better' because of the smaller area of the adhesive In addition, the adhesive need not be limited to being continuous along the sheet. This reduces the risk of damage under the sheet or the discontinuous edge of the sheet. In the case of smoking articles, the adhesive is broadcasted. In the case of a knife removal cover, the adhesive should normally be limited to the portion of the cover that is far from the 7C end of the 200932131, so that the detachable portion of the cover is large enough to expose the amount of unit 0 used. However, if the cover is Completely disassembled, non-aqueous adhesive can be applied anywhere on the side of the lid that overlaps the smoking article. For example, the 'interlinking' spacer can be used to span overlapping surfaces. Adhesives are applied to the sheet rather than smoking articles. Eliminate the sheet wrapped in smoking The front face is in the correct orientation. For any adhesive 10 15 Ο mixture form, the adhesive can be applied to the sheet or smoking article, or both. In addition, the invention is not limited to the above-mentioned winding And a cover made by folding a part of the sheet. Other techniques for assembling a lid surrounding the smoking article may be used. Alternatively, the lid may be assembled first and then attached to the end of the smoking article. In the latter wash, the lid may be outside the sheet. Manufacture of materials, such as molding.
