INSTRUCTIONS: TECHNICAL FIELD OF THE INVENTION The present invention relates to a multi-component puff for cigarette articles and a cigarette article comprising such a multi-component filter. [Prior Art] Filter cigarettes typically comprise a tobacco cut filler rod surrounded by a wrapper and a cylindrical filter aligned end-to-end with the packaged tobacco rod and the attached tipping paper. . Ventilation is typically performed in a perforated manner around the mouth of the mouth to facilitate mixing with the generated mainstream smoke during combustion of the packaged tobacco rod and ambient air. In conventional filter cigarettes, the filter is typically constructed of a cellulose acetate tow plug that is packaged in a porous filter paper. However, filter cigarettes having multi-component filters are known which have two or more sections of filter material for removing particulate components and gas phase components of mainstream smoke. In order to enhance the fragrance of mainstream smoke, it is known to provide a filter having a scented cigarette. In particular, there have been attempts to include flavorings of plant material (such as leaves, seeds or roots) from one or more aromatic plants. In a known example, a filter cigarette having a multi-component filter having a flavor-releasing section containing a mixture of plant materials is provided, and the plant material comprises licorice plant material, ginger root and minced mint leaves. It would be desirable to provide a multi-component filter for use in a smoking article that provides improved flavor enhancement during use, particularly when mainstream smoke is inhaled by a consumer through a filter through a smokable material rod. Mint and menthol flavors of mainstream smoke. In addition, it would be desirable to provide a multi-component filter for use in cigarette products of 200913909 that includes a flavor release section that minimizes the loss of flavor during storage. SUMMARY OF THE INVENTION In accordance with the present invention, a multi-component filter for a smoking article is provided comprising: a mouth end section and a flavour release section upstream of the mouth end section, wherein the flavour release section contains plant leaves and Filter plasticizer.

In conventional fiber filter plugs, the role of the filter plasticizer is to bond the fiber plugs together, increasing the rigidity of the fiber plugs and its compression resistance. The plasticizer is usually used as a solvent for the fiber material and softens the outer surface of the fiber so that the fibers stick to each other. E-glyceryl acetate is often used as a filter for cellulose acetate tow. The filter plasticizer used in the present invention is preferably triacetin vinegar 200913909 "plant leaf" To indicate a material composed of plant leaves, which has preferably been cut or chopped to provide a particulate material. The aroma release section can include any plant leaf that is capable of releasing the fragrance into the mainstream smoke drawn through the multi-component filter. Such plant leaves are preferably non-tobacco plant leaves. The aroma release section can include leaves from one or more plants. In a preferred embodiment, the fragrance released by the foliage of the plant is produced by a volatile compound contained therein, such as oil, which volatilizes upon smoking. Mainstream fumes, rich in volatile oil from plant leaves, flow downstream and pass through the mouth section of the multi-component filter into the consumer's mouth. The volatile oil will remain in the leaves of the plant before smoking. This will help to ensure that the loss of flavor during storage of the multi-component filter and the smoking article of the present invention is minimized, thereby maximizing the fragrance released to mainstream smoke during smoking. The plant leaves in the aroma release section are preferably mashed, cut or otherwise reduced in size. More preferably, the plant blade has a cut width of between about 0.25 mm and about 3 mm. Most preferably, the plant blade has a cut width of between about 1 mm and about 2 mm. Preferably, the plant leaves are dried to a moisture content of between about 8% and about 10%. The plant leaves in the flavour release section preferably comprise herbal leaves. The word "herbal leaf" is used to mean leaves from herbs. A "herbaceous plant" is an aromatic plant without woody tissue whose leaves are used for medical, cooking or aroma purposes' and can release the aroma into mainstream smoke drawn through a multi-component filter. The flavour release section may comprise herbal leaves from one or 200913909 of various perennial or annual herbaceous plants. For example, the 'flavor release section can include, but is not limited to, peppermint, lemon balm 'guinea basil, lemon basil, scallions, scallions, basil, lavender, sage, tea, thyme and carvi. In a particularly preferred embodiment of the invention, the plant leaf in the aroma release section comprises mint leaves. The oil content of the mint leaves is preferably at least about 0.6% by weight. The inclusion of mint leaves in the aroma-releasing section of the multi-component filter of the present invention will facilitate an improved manner of providing a mint and menthol flavor to the main stream of the smoking article. The mint-containing multi-component filter-containing cigarette article of the present invention can be advantageously provided with a stronger load and a menthol flavor compared to a conventional menthol cigarette. In a particularly preferred embodiment of the invention, the plant leaf in the flavor release section is mint leaves and the filter plasticizer is triacetin. Surprisingly, it has been found that the inclusion of mint leaves and triacetin in the flavor release section of the multi-component filter and cigarette article of the present invention will help to increase the production of menthol and other volatile oils released from the mint leaves. Mint and menthol scent. This will be explained by the results shown in Table 1 below. Table 1 shows the amount of special aroma compounds released into the main stream by the mint leaves in the flavor release section of the filter cigarettes (samples 1 and 3) of the present invention having the general structure shown in Fig. 1. The scent release section is composed of a cellulose acetate tow plug having mint leaves and triacetin distributed therein. Table 1 also shows the flavor release section which is a filter cigarette (samples 2 and 4) having the same structure as Samples 1 and 3 but not according to the present invention and in which the flavor release section does not contain triacetin. The amount of aroma compounds released by the mint leaves. Each sample contained 40 mg of 200913909 mint leaves. Not all compounds released from the mint leaves are measured. Each sample was taken under ISO conditions, and the obtained flue gas extract was analyzed by GC-MS single ion monitoring to determine the content of volatile compounds in the flue gas. For full scan analysis, the scan range is from 30 to 400 m/z (anion mass to charge ratio). As can be seen from Table 1, triacetin and mint leaves are used in combination in the flavour release section of the filter cigarette of the present invention as compared to the non-inventive filter cigarette in which the flavour release section does not contain triacetin. It can increase the content of aroma compounds released from the mint leaves to the mainstream smoke during smoking.

Therefore, the acetic acid content released in the filter during smoking was significantly higher than that of the non-smoking according to the invention of 200913909, as shown by the results in Table 2 below. The size and properties of the filter cigarette of the present invention (Sample 5) having the structure shown in Fig. 1 are listed in Table 2. The mouth end section of the filter cigarette is composed of a cellulose acetate tow plug, and the flavor release area is composed of a cellulose acetate tow plug in which mint leaves and triacetin are distributed. The size and nature of the filter cigarette (Sample 6) which is the same structure as Sample 5 but which is not in accordance with the present invention and in which the flavor release section does not contain triacetin is also listed in Table 2. As can be seen from Table 2, the scent of the multi-component filter of the filter cigarette (sample 5) of the present invention is compared with the non-inventive filter cigarette (sample 6) containing only triacetin in the mouth end section. The combination of triacetin and mint leaves in the release section significantly increases the amount of acetic acid released in the filter.

The method and apparatus for making such beads are also described in Japanese Patent Application No. 1 8 2 8 4 2 . These beads can have the same or different diameters and colors. For example, the color of the beads can show the type of flavoring they are impregnated with. Preferably, the beads have a diameter of between about 0.2 mm and about 2 mm. The liquid flavoring material used in the rod end section of the multi-component filter of the present invention may comprise one or more perfume ingredients to create a Particular aroma form -12-200913909, and it can be a natural extract, a synthetic fragrance, or a combination thereof. Liquid flavors and flavors that may be included in the rod end section of the multi-component filter of the present invention may include, but are not limited to, menthol, mint, spearmint, coffee, tea, spices (such as cinnamon, cloves, and Ginger), cocoa, vanilla and fruit flavorings. In a preferred embodiment of the invention, the plant leaves in the flavour release section are mint leaves, and the rod end section of the multi-component filter preferably comprises a liquid thin brain enrichment. In these embodiments, the menthol flavoring supplied to the rod end section promotes the release into the mainstream smoke, while the mainstream smoke is inhaled through the filter during smoking and is passed through the flavor release zone. The mint leaves in the section provide menthol and mint flavors that are released into the downstream mainstream smoke. The mouth end section may comprise at least one flavoring material, such as the flavorings previously mentioned for the rod end section. If it is a flavoring material, the mouth end section preferably comprises one or more filaments impregnated with a liquid flavoring. The multi-component filter of the present invention may comprise a mouth end section containing at least one flavoring material, or a rod end section containing at least one flavoring material, or a mouth end section containing at least one flavoring material and containing at least one flavoring material Rod end section. When the mouth end section and the rod end section contain at least one flavoring material, the at least one flavoring material in the mouth end section may be the same as or different from the at least one flavoring material in the rod end section. In use, when mainstream smoke is drawn from the smokable material rod through the multi-component filter 'mouth', the scent will be released into the mainstream smoke by the plant leaves in the scent release section. In a particular embodiment of the invention, at least one flavor scent in the rod end section will also be released upstream of the scent release section as previously described above. In a particular embodiment of the invention, at least one of -13-200913909 flavors may alternatively or additionally be added to the mouth end section and the flavor will also be released downstream of the flavor release section. Thus, the multi-component filter of the present invention enhances the scent of the mainstream smoke drawn into the filter by two or three times during smoking. The multi-component filter of the present invention can be produced by forming individual continuous thin rods comprising multiple units of each individual section of a multi-component filter, and then these individual thin rods are then known in a known manner Combined in one or more stages to form a continuous filter-nozzle comprising multiple units of multi-component filters. The continuous filter rod is then cut into segments at a fixed spacing by a cutting mechanism to produce a series of separate multi-component filters of the present invention. Preferably, the smoking article of the present invention comprises a packaged fine cut tobacco rod. Preferably, the smoking article of the present invention has a nicotine-free dry particulate material (NFDPM) or a "tar" release of up to about 10 mg. The "tar release amount" is preferably between 丨mg and 1〇mg, and more preferably about 6 mg. The smoking article of the present invention may be packaged in a container, such as a soft or hard case, with an inner liner coated with one or more flavorings. In the first aspect of the invention, the plant leaves in the flavor release section are dispersed among the fibrous filter plugs, preferably cellulose acetate tow. Applying the filter material to the filter material by spraying the filter plasticizer onto the individual fibers in a conventional manner, preferably after applying the plant leaves to the filter material. Distributed along the length of the fiber filter plug. For multi-component filters having a straight-14-200913909 diameter of between about 7.5 mm and about 78 mm, the mint leaf content per millimeter of flavor release section is preferably between about 1 mg and about 4 mg. . The filter plasticizer may be present in an amount of from 丨% to 9% by weight of the fiber filter material, preferably 5% or less by weight of the fiber filter material. If the amount of triacetin is used as the filter plasticizer 'triacetin, the amount is preferably 5% by weight of the cellulose acetate tow or other fibrous filter material. Such triacetin levels have been found to provide satisfactory stiffness to the fibrous filter material plug of the flavor release section without hindering the release of flavor by the mint leaves. It is significantly lower than the triacetin content of conventional cellulose acetate tow filter plugs, which are typically at a level of about 7% by weight. In the cigarette article of the first aspect of the invention, the length of the aroma segment is preferably between about 5 mm and about 22 mm, and more preferably between about 10 mm and about 15 mm, preferably the length. It is about 12 mm. In the smoking article of the first aspect of the invention, the mouth end section may comprise a hollow tube or recess. The hollow tube or recess can be formed when the multi-component tip is attached to the smokable material rod by tipping paper to form the smoking article of the present invention. In such a smoking article, the downstream end of the aroma-releasing section can be seen at the mouth end of the multi-component filter via a hollow tube or recess which allows the consumer to see the plant leaves dispersed in the plug of fibrous filter material. When the mouth end section comprises a hollow tube or recess, the length of the mouth end section is preferably between about 3 mm and about 4 mm. In a second aspect of the invention, the flavour release section comprises a plant leaf plug (preferably a compressed plant leaf) coated with a filter plasticizer. Such plant leaf plugs are preferably free of any other materials. The filter plasticizer can be applied before or after the formation of the plant leaf plug. 200913909 The amount of filter plasticizer is preferably from about 5% to about 1.5% of the weight of the plant leaves. If the flavour release section comprises a mint leaf plug coated with triacetin, the amount of triacetin is preferably between about 0.5% and about 1.5% by weight of the mint leaf. The demand for triacetin in such cigarette products is much lower than that of cigarette products in which the mint leaves are distributed in the fibrous filter plug, because triacetin is only used to increase the fragrance, not to make the filter The plug becomes hard. In the cigarette product of the second aspect of the invention, in order to prevent the mint leaf from being lost by the filter, the mouth end section preferably contains a fibrous filter material. In the smoking article of the second aspect of the invention, the length of the flavor releasing section is preferably between about 3 mm and about 12 mm. In a third aspect of the invention, the multi-component filter of the present invention further comprises a second flavour release section between the mouth end section and the previously described flavor release section. The inclusion of the second flavour release section also enhances the aroma delivered to the consumer during smoking. The second flavour release section preferably contains tobacco leaves. Tobacco leaves can be crushed, cut or otherwise reduced in size. The tobacco leaves are preferably cut finely, and the preferred tobacco leaves have a cut width of 0.4 mm. Preferably, the tobacco leaves in the second flavour release section are dried. The moisture content of the tobacco leaves is preferably about 15% by weight or less. The length of the second flavour release section is preferably between about 6 mm and about 12 mm, more preferably between about 6 mm and about 1 mm. The second flavour release section can include tobacco leaves containing, for example, sugar or a moisturizing agent.

In the longitudinal direction of 60, 60 is not shown. Among the 4th and 60th multi-component filters: the agent can remove the components. At least one suction Stone or sepiolite, which is equipped with a multi-component filter 4 having a multi-component filter of the 50-type multi-component filter 4 of the Su 70 multi-component filter 4, several Viscopearl®, which is not shown in the system J), 3, 60 Replaced by the recess of the multi-component filter of 70, there is actually a structure similar to the multi-component filter 4 of Figures 3 to 6-19-200913909, which includes three end-to-end adjacent sections: the mouth end section 1 2 Which is away from the packaged tobacco rod 2; a fragrance release section 14 which is located upstream of the mouth end section 12; and a rod end section 32 which is located upstream of the fragrance release section 14 and Abut and abut the packaged tobacco rod 2. The mouth end section 12 and the aroma release section 14 have the same structure as described previously in the filter cigarettes 30, 40, 50, 60 shown in Figs. The flavour release section 14 contains a finely cut mint leaf plug which is coated with triacetin and compressed, rather than a cellulose acetate tow plug in which mint is distributed. The amount of triacetate (.: oil ester is about 0.5% to 1.5% by weight of the mint leaf. The mouth end section 1 2 and the rod end section of the filter cigarette 80 shown in Fig. 8 42 may be either party or contain flavoring at the same time as previously described for the filter cigarettes 30, 40, 50, 60 shown in Figures 3 to 6. The filter cigarette 90 shown in Figure 9 has A multi-component filter 4 comprising four end-to-end abutting sections: a mouth end section 12 remote from the packaged tobacco rod 2; a first flavor release section 92, located in the mouth end region Upstream of the segment; a second flavour release section 14 that is located upstream of the first flavour release i: section; and a rod end section 32 that is upstream of the second flavour release section 14 and abuts And adjacent to the packaged tobacco rod 2. The mouth end section 12, the second flavor release section 14 and the rod end section 32 have filter cigarettes 30, 40, 50 as previously shown in Figures 3-7, The same structure of the mouth end section, the flavour release section and the rod end section described in 60, 70. The first flavour release section 92 contains densely stacked fine cut tobacco plugs. The filter cigarettes 10, 20, 30, 40, 50, 60, 70' 80, 90 of the specific embodiment of the present invention shown in Figures 1 to 9 are first made into a multi-component filter 4, and then The packaged tobacco rod 2 manufactured in the conventional manner is connected to 200913909, which is joined by the tipping paper 6 using a known filter cigarette manufacturing apparatus. To manufacture each of the multi-component filters 4, it is produced in a known manner. A plurality of continuous rods of multiple units comprising each of the sections 1, 2, 4, 3 2, 9 2 of the multi-component filter 4 are then combined to form a continuous filter rod comprising a plurality of units of the multi-component filter 4. The continuous filter rod is then cut into segments at a fixed spacing by a cutting mechanism to produce a series of separate multi-component filters.
