Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a nozzle and a mouthpiece for smoking articles such as cigarettes. [Prior Art] Benefits need to provide a distinctive appearance of the end of the cigarette. Cigarette counterfeiting is a major problem, and producing a distinctive and/or extraordinary appearance of a cigarette brand is an important way to curb the brand. Moreover, increasing the restrictions on cigarette advertising and packaging means that the appearance of cigarettes is one of the few ways cigarette manufacturers can differentiate their products from those of other manufacturers. Providing a cigarette filter with a distinct end appearance can help achieve these goals. Concave filters are well known in the tobacco industry and provide a means of producing the appearance of the unique end of the cigarette. They are typically manufactured by continuous flow of filter segments across a relatively rigid insert wrapper at a pitch. A concave filter is obtained by cutting the filter flow in the region of the filterless element - the hard insert packaging paper provides sufficient hardness for the manufacture and use of the finished cigarette product without damaging the end of the filter. The concave filter can be added to one, two or more (e.g., fiber) filter segments. When two or more segments are used, there are typically different filter configurations - such as different media or different additives (such as flavors or adsorbents). Squeezed plastic cigarette holders for cigarette filters are also known. For example, please refer to US 3,396,733. This provides another way to produce a distinct cigarette end appearance. These mouthpieces generally have a hollow inner body with a plurality of radial support ribs. These mouthpieces can be used as downstream or mouth end sections of multi-stage filters and are collectively referred to as SPF (Formed Plastic Filters). Yet another means of providing a distinctive cigarette filter is from Filtrona 201240615 CPA Ferry, as exemplified in WO2007/135414. These filter backs are also packaged in a paper package (which is compressed along a portion thereof) according to the mouth body 'and then wrapped in a conventional outer card package. When the filter is cut in this area, the inner packaging of the embossing produces a grooved appearance. When used at the end of the filter, it produces a distinct appearance of the end of the cigarette. This filter can be used as a single unit product or as a section within a multi-section filter. There is a need to provide a filter with a more distinctive end appearance that is difficult to counterfeit. SUMMARY OF THE INVENTION According to the present invention, there is provided a tobacco smoke filter (or filter element) comprising: a longitudinally extending (e.g. cylindrical) core comprising a tobacco smoke plum, and an outer wrap extending the core longitudinally Coupling; wherein the longitudinally extending core comprises one or more of a channel extending longitudinally from the downstream of the core, and wherein the downstream end of the outer package extends past the downstream end of the core about which it is twisted to filter The downstream end of the mouth defines a (eg tubular) cavity. The outer wrapper extends beyond the downstream end of the core to define a cavity or pocket, such as a tubular cavity/recess, at the downstream end of the concave filter that is wrapped around it (e.g., to extend the downstream end of the core). The combination of the recessed filter and the downstream end (nozzle end) of the filter containing the visible channel(s) extending longitudinally upstream from the downstream of the core provides a very sharp end appearance that is difficult to counterfeit. In one example, the longitudinally extending core comprises a hollow body of tobacco smoke filter. The tobacco smoke filter material can be, for example, a cellulose acetate filter. The cross section of the hollow tube (and therefore the channel) can be circular or non-circular. The wall or wall of the hollow tube of a circular or non-circular cross section defines a channel extending upstream from the downstream section -4- 201240615. The channel generally does not extend the full length of this part. It is anticipated that these types of filters will result in lift to improve the perceived characteristics and cooler smoke because the mixing and circulation of the plume entering the tube section and thereafter entering the recess end before entering the front of the smoker can be controlled. According to one aspect of the invention, a tobacco smoke filter (or filter element) is provided comprising a longitudinally extending (e.g. cylindrical) core comprising a tobacco smoke filter; and an outer wrap extending around the longitudinally extending core Wherein the longitudinally extending core comprises a downstream element (eg, a downstream section), the downstream element comprising a longitudinally extending tube having a plurality of dividing ribs, the ribs extending generally inwardly (eg, radially inward) to define (plurality) Longitudinally extending a plurality of dividing ribs therebetween; and wherein the downstream end of the outer package extends over the downstream end of the core around which the beta is joined (and extends past the downstream end of the downstream element) to match the filter The downstream end defines a (eg tubular) cavity. Extending a radially inner surface of the package beyond the downstream end of the core about which it is twisted (eg, by the downstream end of the longitudinally extending core) defines a cavity or pocket at the downstream end of the concave filter, such as a tubular cavity / recess.

It can be smoked, can control the inflow...the pipe sign and the cooler A & k inside' and enter the end of the recess 201240615 The smoke flow before entering the front smoker's crotch According to another aspect of the present invention, there is provided a tobacco smoke filter (forming a filter element) comprising a longitudinally extending (e.g. cylindrical) core, comprising a tobacco smoke filter; and an outer package extending longitudinally Core kneading, wherein the longitudinally extending core comprises: a downstream element comprising a longitudinally extending (e.g. cylindrical) core of the tobacco smoke filter; a first inner package extending around the longitudinally extending core; and optionally Second, the second inner package =: it is twisted around the first package; the first package has a shaped (wavy undulating) outer surface defined by a second inner or outer package - a longitudinally extending channel [eg ,at least a longitudinally extending channel extending longitudinally upstream from a downstream end of the downstream core; i having a downstream end of the intermediate outer package and/or a downstream end of the first inner package extending over the downstream end of the core around which the twist is joined To define (eg, a tubular) cavity at the downstream end of the filter. Extending over: the radially inner face of the package at the downstream end or the second inner face of the first inner package < defining a cavity/recess at the downstream end of the concave filter (around the longitudinally extending core/downstream core) For example a tubular cavity/recess. The first ~ inner packaging town is a rolling or non-venting material. It is preferred to be ventilated. The second inner package (砮 present) can be a vented or non-vented material. The (or each) channel may be longitudinally upstream from the downstream end of the downstream core. Preferably, the shaw or per-channel extends only a portion of the length of the downstream core. The 1 hai or per-channel may preferably be substantially deep in its longitudinal direction, although there may be variations, such as the channel approaching the seal = end. The (or each) channel may (alternatively or additionally) extend longitudinally downstream (into the recessed region) from the downstream end of the lower jaw. 7 -10- 201240615 The first package may, for example, be a sheet which is preferably wrapped with a forming surface of the longitudinally facing second outer surface of the outer package (corrugated). The pattern is at least in the second package or the outer wave, the text, the wave channel - for example, from the downstream core; the 疋 j solid or a plurality of longitudinally extending - channels may be provided with the first package 2:: turn The end extends longitudinally (upstream). Each downstream end of the downstream core is undulated by the extension of θ, and can be &#; One package is on the two surfaces r to swim 4 and the second package or to extend the channel. However, 嗳0> - the surface of the downstream core that defines the longitudinal slab table can be consistent with the inner surface of the corrugated surface, leaving only ^^^/, leaving a channel between the first outer packaging. The second (or each) portion is referred to herein as , t 〜 under the first inner package and the second inner package or including the longitudinal channel (e.g., it contains corrugations).卩之5海 The bait is a groove or a grooved part. This is the downstream core of the channel (through the cross section of the core) (or is referred to herein as the rod or rod portion 1 , in this aspect of the invention, the downstream (recessed) end of the second paste has a groove (4) In addition to the recessed part, the outer end of the downstream core (non-recessed end) can have other: trough. In the example, the downstream core contains 3 m/part at each end. And a single central rod 'as the remaining full length of the downstream core. This groove configuration can have other advantages' ie the filter material in the downstream core (eg fiber:: acid wire can be reduced) because of the pressure drop of the rod (PD/亳米) is higher than: the pressure drop of the groove. # This aspect of the invention provides a recess at the mouth (downstream) end, with a groove or "CPA" element (segment) underneath, one or more longitudinal grooves = or the groove faces the mouth end to produce a sharper end appearance. For more details, see 'More details -11- 201240615'. Other components (segments) with one or more filters upstream of the CPA section. Located in the CPA section Any of the filter segments further upstream preferably have a filtering characteristic that is different from the CPA segment, such as 'incorporating granular additions And/or aroma. The downstream core may comprise up to 23 channels, preferably between 14 and 20 channels, [for example extending longitudinally from the downstream end of the core to the upstream (a circumference of approximately 25 m3 of filtration, Mouth)] The total cross-sectional area of these channels can be between 2 and 12% of the total cross-sectional area of the nozzle, preferably at least 4%, and more preferably between 4 and 8%. Careful control of the number and/or depth (eg, controlling the embossing of the first package) can provide improved soot performance. This can be achieved by increasing the depth of the corrugations, preferably by increasing the useful corrugation surface area of the smoke, and And optionally accompanied by an increase in the spacing of the corrugations, i.e., by increasing the number of the corrugations, the corrugations are expanded. For example, the poop according to the present invention may be downstream of the downstream core. 1 5 channels, Beans 0.45 mm deep, and about 1.5 mm spacing. Again, /, is ancient, „ ^ 'The other filter can have a deep channel of 0.32 mm, the number of channels is 23, y ^ . Engaged with 1. 〇 5 mm spacing. These examples can be used for the ripple of the filter smoke _ _ , ^ ^ , the product is generally slightly less total The surface area of the grain, because the ripple of the corrugation__4 is against the outer package and cannot be effectively filtered. The first package can extend only vertically from the upstream end of the core extending longitudinally downstream of the downstream end of the second inner package to the downstream extension. The lesser portion of the length of the downstream core includes no longitudinal extension, preferably the length or outer package of each channel defines a channel from the downstream core to the v-channel, and one channel from the downstream main, each Ditch #分' the channel to which the downstream core extends. & 2 mm or larger, preferably -12-201240615 between 2.5 mm and 23 mm, preferably between 3 mm and i5 mm More preferably, between 3 · 5 mm and 9 mm. The length of one or more of the channels extending from one end (upstream or downstream) may be different from the length extending from the other end, or they may be the same length. The channels at the ends of the downstream core can be between 7 and 8 mm long. The channel at the ends of the downstream core may be between 3 and 4 mm long, for example 3 75 mm long. The provision of channels of these dimensions means that the performance of the downstream core (tar retention, etc.) can be accepted 'further' and should ensure that the advantages of the invention (e.g., consistent pressure drop, enhanced retention) are obtained. The longitudinally extending core may comprise only the downstream core, or may comprise one or more (e.g., 1, 2, 3 or 4) other elements (one or more segments) including a tobacco smoke filter. The other components are located upstream of the downstream core. Tobacco smoke filters can be, for example, those used in the manufacture of conventional tobacco smoke filters (usually filamentous, fibrous, reticulated or extruded). The filter material may be a natural or synthetic filamentous tow such as cotton or plastic, such as polyethylene or polypropylene, or a cellulose acetate tow. For example, it may be natural or synthetic staple fiber, cotton, mesh material such as paper (usually wrinkled) and synthetic non-woven fabric, and extruded materials (such as starch, synthetic foam). Any type of mouth filter known for use in cigarette filters can be made up of other components (other segments) such as "wrapping acetic acid", "not wrapping acetic acid j, "randomly oriented acetic acid", "cellulose acetate" or " Active acetic acid. Any number of elements, preferably different features, may be used upstream (e.g., "C P A ") elements upstream, such as 1, 2, 3, or 4. In the case of two or more other components including a tobacco smoke filter, these other components preferably have different mouth characteristics, such as the cellulose acid-13-201240615 segment and the "active acetic acid" portion. One or more of the other elements may contain a (e.g., granular) additive material (e.g., activated carbon) suitable for use in cigarette puffs, and/or a fragrance such as mint. The additive material may be added in the form of granules. The granule additive may be any tobacco smog suitable for use in tobacco smoke filters. For example, active anaesthesia, zeolite, ion exchange resin (for example, weakly basic anion exchange resin), sea sac Stone, Shixi gum, oxidized soda, molecular sieve, carbon polymer resin and: algae. The particulate additive can be a mixture of two or more materials. The additive may comprise a fragrance such as mint - for example the additive may be the sepiolite particles to which the mint 1 is applied. If the longitudinally extending core of the tobacco smoke filter comprises one or more fully encapsulated (eg embedded) packages in which the additive is embedded, the additive may be a particulate additive, like activated carbon (see above), which is for example sealed The individual packs or pods within the filter material as particulate additive particles are substantially separated from the filter material and are completely enclosed therein. In another example, one or more fully enclosed (e.g., buried) packets may be one or more fragile capsules or one or a plurality of frangible microcapsules. The one or more capsules or one or more microcapsules may comprise a plurality of vehicles - for example, a fragrance and/or a liquid, solid or other material that aids in the filtration of smoke. The use of capsules or microcapsules is well known in the art. The sin (or one) other element may comprise a longitudinally extending cylindrical insert of cellulose acetate filter. The longitudinally extending cylindrical insert of the cellulose acetate filter may in turn comprise a package such as a porous or non-porous insert package. The wrapped filter's component is “wrapped with acetic acid”. t or filter element. The other elements may comprise a longitudinal extension of the cellulose acetate filter material, which in turn comprises a particulate additive', optionally having a perforated or non-porous package. Such filters/components are referred to as "active acetic acid" filters or filter elements. The (or one) other component of the tobacco smoke coffin may include a rod-shaped portion of the tobacco smoke filter material having a fully encapsulated (eg, embedded) additive (eg, a particulate additive) therein. package. The rod core of the tobacco smoke filter may optionally have an additional package (e.g., porous) that it wraps around the rod core. A full-sealing additive package is provided in the tobacco smoke filter core with the effect of removing the additive from the second end of the core (this is due to the presence of a tobacco smoke filter between the additive package and the end of the section). A single adultery I can be made, for example, by the method and apparatus disclosed in WO 02GG6/G5 9 1 34, including a tobacco smoke coffin of a rod-shaped core of a tobacco smoke material: the core is fully enclosed (eg, embedded) (or At least one) additive (eg, particulate additive) package. (4) The (or —) other elements T of the tobacco smoke filter include the rod shape of the smoke plume... and the package around the rod core „that is: (eg granule additive), containing the radial inner surface of the σ sodium - Or more, in the package with additives attached to the more end of the knife at the downstream end of the core, spare n, additives. There is no additive at the downstream end of the additive-containing package: there is an effect of the additive away from the downstream end of the core (this is because there is no additive on the core::: package). Preferably, the additive-containing package is wrapped around the core of the core::: and J, and there is no addition around the circumference of the rod, including the rod-shaped core of the tobacco material and the mist around the rod-shaped anger, considering the additive) Tobacco smoke, &#;########################################################################################### - 201240615 or non-porous.

For paper, &, t 1 such as insert wrapping paper, such as hard plug-in paper. The outer packaging can be porous 匕 匕 gray non-porous. The outer packaging can be paper with a basis weight of about 40 to about 120 g / m2. For a standard oversized (about 24 - 25 mm) concave overwrap, the basis weight can be & 2 ι J from about 80 to about 120 g/m2, for example, a basis of about 100 g/m2. Heavy. In the group ^ jujube long or slender concave filter (for example, reduced to a circumference of about 16-17 mm) 'outer packaging can be a lower basis weight, for example about 50g / m2: insert wrapping paper. Notice ' can also The harder tipping paper is used in combination with the insert wrapping paper to provide the concave filter cigarette product with the desired hardness. In the example of this aspect of the invention, the first inner package can be extended to the downstream. / downstream of the downstream element, where it fits to the lower, winter & boundary of the filter (eg 'alone or with the outer package') (eg tubular) cavity In the case of the case, the second inner package of the downstream core may be omitted from the 'this is ·", and other packages (for example, for wrapping the concave filter finished product package 6-201240615) can be combined to filter the filter. It is to be noted that, for example, a first inner package having a basis weight of 80 g/m2 (e.g., embossed) can provide a low weight, for example, an outer package of 40 g/m2 which provides sufficient rigidity in the recess. / or the second inner package can be colored or dyed to enhance the sharpness of the end appearance. Preferably, it is in contrast to a color or pigment such as a white enamel. The first inner package need not extend beyond the downstream end of the downstream core. In such an example, the downstream core and the inner package can be packaged in a second inner package (as is conventionally used for this type of "CPA" filter) before being packaged in a (heavy insert package) outer package. In the mouth element, the outer package defines a cavity when assembling the finished concave mouthpiece. In other examples, the second inner package can be omitted. It should be noted that the 4b case is earlier than 4 s #^一Ή10 which is different from the end portion of the first inner package extending downstream into the recess (or defined) of the finished filter product. In the mouthpiece cigarette according to the present invention, the mouthpiece of the present invention (or the filter comprising the element of the invention (4)) is oriented with the mouth end facing the tobacco, and the hook to the wrapped tobacco rod can be used, for example, by a ring mouthpiece. [Whether the wrapped (wrapped) filter and the adjacent end of the rod are combined to reveal a large number of filter packages], or better by the full mouthpiece package (around the length of the tip of the tobacco rod and the abutting end), link to i . Wrapped tobacco. The cigarette may comprise a mouthpiece package (e.g., a cigarette holder paper) that is combined with a filter or mouth package to provide a desired (e.g., further increased) hardness to the concave filter cigarette product. Any filter or filter cigarette according to the present invention may be non-vented or may be vented by methods well known in the art, for example, by using pre-perforated or vented packaging (plug-in packaging), and/or packaging (plug-in packaging) and outside the mouthpiece. The laser perforation of the package is ventilated. Vented full mouthpiece outer packaging can also be ventilated -17- 201240615 or with venting holes, and in the smoked ventilation product, aligned throughout the outsourcer. The venting through the filter insert package through the two can be made in the tear-through hole perforation package and the mouthpiece package is usually ventilated with the penetrating insert, or through the mouthpiece or the cigarette. Both of the packages are simultaneously limited by the filter or the filter additive according to the present invention, for example, the through hole of the product of activated carbon is selected from the group consisting of being selected from upstream, downstream, and in line with the additive: Thus, the filter or filter scent according to the invention. . . According to the performance of ventilation and filter, l虱. The desired longitudinal direction of the cigarette filter is selected, for example, from upstream and downstream, and is aligned with the additive package (or small μ or . . . - or two regions. Preferably The ventilation in the mouthpiece or the mouthpiece cigarette according to the present invention may be limited to the longitudinal direction of the mouthpiece or the tipping cigarette, for example, as described above, in alignment with other elements of the nozzle or filter element belonging to the "active acetic acid". Often, for example, the first additive package (if any) is vented upstream and/or aligned therewith. When there are two or more, there may be aeration between the second additive portion (or tablet or portion). According to another aspect of the invention, a multi-bar filter is provided comprising a plurality of (e.g., 2, 4, 6, etc.) filters (or filter elements) as described above and/or described herein. The multi-rod and its manufacturing method are well known in the art. The present invention will now be described with reference to the following examples and drawings. [Embodiment] [Embodiment of the Invention] Example 18- 201240615 Figure 1 shows the genus A "concave spf" filter mouthpiece of the present invention. The filter comprises: a longitudinally extending cylindrical core member (1); and other elements (7) comprising tobacco smoke (4) a member (1) comprising a longitudinally extending cylindrical tube in the form of a length of 5 mm Extruded HDPE portion 'The cylindrical tube has six dividing ribs that extend radially inwardly into the longitudinally extending inner body in the form of a hollow hollow tube. The ribs (along with the radially inner face of the cylindrical tube and the radially outer face of the inner body) Defining six longitudinally extending channels. The hollow tubular inner body defines other channels extending longitudinally within the inner body. The cross-sectional profile of the HDPE portion (1) is indicated by (2). Other elements include the form of cellulose acetate and Cylindrical insert of tobacco smoke filter material 18 mm long.

The outer package is applied by means well known in the art. This produces a concave filter with an overall length of 27 mm. It should be noted that the combination of the recess (6) and the downstream (end) end of the cross section (2) of 70 pieces (1) provides a very sharp appearance that is difficult to counterfeit, which The cross section (2) comprises a longitudinally extending upstream of the downstream end of the core/downstream element. Fig. 2 shows an example of another "concave SPF" mouthpiece which is not an example of the invention. The filter comprises: longitudinally extending A cylindrical core comprising a downstream element (la) 'a first other element (3a) comprising a tobacco smoke filter; 201240615 and a second other element (7a) comprising a tobacco smoke filter. The downstream element (1a) comprises an extruded 5 mm length of the HDPE portion in the form of a longitudinally extending cylindrical tube having six dividing ribs extending radially inwardly into a longitudinally extending inner body in the form of other hollow cylindrical tubes. The ribs (along with the radially inner face of the cylindrical tube and the radially outer face of the inner body) define six longitudinally extending channels. The hollow inner body defines other channels extending longitudinally within the inner body. Therefore, the cross-sectional profile of the HDPE portion (1a) is similar to that shown in (2) of the second figure. The first other component (3a) comprises a cylindrical insert of tobacco smoke filter material in the form of cellulose acetate and 8 mm long. And positioned directly upstream of the extrusion (la). The second other component (7a) comprises an "active acetic acid segment" in the form of a cylindrical insert of tobacco smoke filter material in the form of a cellulose acetate fiber comprising a particulate additive in the form of activated carbon. The second other element (73) is 1 mm long and is positioned over the filter end (in the filter cigarette product, the end is attached to the tobacco column). The nozzle sections (la), (3a) and (7a) are connected together using a plug-in package (4) with a basis weight of 27 g/m2 by means of the skill of the art. ^ 1 〇〇g/m2 plug-in packaging (5) Extending the core (ie, elements (7a), (3a) & (la)) in a longitudinal direction to completely package the anger; the downstream end of the outer package (5) extends over the downstream end of the longitudinally extending core [and its winding The downstream element (la) is coupled to define a tubular cavity or recess (6) that is 4 mm long at the downstream end of the filter. The outer packaging is applied by means of the skill of the art. This produces a concave filter with an overall length of 27 mm. Again, it will be appreciated that the combination of the recess (6) with the downstream element (1 a) having the downstream end (mouth end) of the cross section (2) provides a very sharp appearance that is difficult to counterfeit, the cross section (2) containing the core from A channel extending longitudinally upstream of the downstream end. -20- 201240615 Fig. 3 shows an example of the mouth of the present invention.

Fig. 4 shows a concave cpa filter mouthpiece belonging to another example of the present invention. The sigma nozzle includes: a longitudinally extending (e.g., cylindrical) segment containing a downstream core (8a); and other elements (1 1)' located above the downstream core. The other component (1 1) comprises a 12 mm long "active acetic acid segment" in the form of a cylindrical insert of tobacco smoke filter material. The tobacco smoke filter material is in the form of a cellulose acetate fiber comprising a particulate additive in the form of activated carbon. The downstream core (8a) comprises a 1 mm long longitudinal cylindrical insert comprising a cellulose acetate fiber packaged in a first inner package (9a), the first inner package (9a) comprising a basis weight of 80 g /m2 plugin packaging. The insert package forming the inner package (9a) is embossed in one of its lengths by 15 grooves of about 45 mm deep and about 1.5 mm pitch. The insert is packaged in the inner package (9a) so that it is wrapped around the length of the unfilled insert packaging area by about 5 mm ("bar area") at its upstream end and is embossed at its downstream end ( The "groove area" surrounds the remaining 6 mm length. The downstream core (8a) is joined to the other component (11) by a hard plug outer package (12a) of the weight i〇〇g/m2, and the downstream end of the outer package (12) extends over it to fit it. The downstream end of the core (8a) is 4 mm, with a tubular cavity of 4 mm in length at the downstream of the filter. The inner package (9a) is packaged (i2a) with 15 grooves or channels extending longitudinally upward from the downstream end of the downstream core and visible in the recesses/cavities formed by the outer package (12a). It will be appreciated that the combination of the recess with the slotted end of the downstream core (8a) bounded by the inner package (9) and the outer package 12 provides a distinct end appearance that can be seen from the end of the filter. It should be noted that the above-mentioned filter including a multi-stage concave filter can be made by the conventional means -22-201240615. It should be noted that the above filter can be used to manufacture filter cigarettes by conventional means.
