1270350 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to reducing sidestream smoke of burning cigarettes and other smoking products. In particular, the present invention relates to a cigarette paper, cigarette wrapper, or cigar wrapper or other similar tobacco product having a better ashing effect while reducing sidestream smoke visible to the naked eye. [Prior Art] # There have been various attempts to reduce or eliminate sidestream smoke emitted when cigarettes are burned. Applicants have also developed a variety of systems for controlling cigarette sidestream smoke. The results are described in detail in Canadian Patent Nos. 2,054,735 and 2,057,962; U.S. Patent Nos. 5,462,073 and 5,709,228; and the published International Application WO 96/ 22031, WO 9 8/1 61 25 and WO 99/53778. Other sidestream smoke control systems have been developed for the addition of filter or adsorbent materials to tobacco, filters or wrappers. These systems are exemplified in U.S. Patent Nos. 2,755,207, 4,108,151 and 4,225,636; European Patent Application No. 0 740 907 and No. 0 251 254; and International Application WO 97/27831 and WO 99 /53778. A low side flow cigarette paper is described in U.S. Patent No. 2,755,207. The smoke produced when the paper is burned contains almost no unpleasant constituents. The cigarette paper is a fibrous material and is present in the form of a fiber in which fine particles of a mineral ruthenium catalyst are closely contained. This almost non-combustible cigarette paper remains almost unchanged during combustion and functions as a catalyst for improving the burning rate of cigarette paper. The appropriate Zeiss catalyst 4 comprises an acid-treated clay, a heat treated kaolinite, and a sulphuric acid salt (which contains some highly mobile argon atoms). The mixture of the substance includes aluminum, bismuth, titanium, chromium oxide, and cerium oxide. Other tellurides include oxides having a weight ratio of ruthenium to aluminum of 9. U.S. Pat. The weight of at least 50% of the aluminum filler in the cigarette paper is the composition of the organic vapor phase in the tobacco smoke. As a result, the amount of sidestream smoke visible to the naked eye in the smoke can be clearly observed. Γ-aluminum is generally the most familiar with aluminum, which is ground to a fine mesh of the composition of the organic vapor phase and the total mass of the sidestream smoke in the paper using a 300 mesh mesh screen which is disclosed in U.S. Patent No. 4,225,636. The use of the break can reduce the sputum of the flue smoke emitted from a burning cigarette. Activated carbon is preferred as a carbon source. The amount of visible sidestream smoke was slightly reduced. Up to 50% of cigarette paper consists of particles. The coated 6-carbon paper can be wrapped as a wrapper with a layer of conventional cigarette paper. The European Patent Application No. 6, published November 6, 1996, shows the use of zeolites in cigarette tobacco to alter the volatility of cigarette kings. The removal of various components in mainstream smoke, such as the collection, can significantly change the sidestream smoke. The composition of the zeolite particles used is between ^ and 1.2 mm.

12 1270350 The ashing effect of desire. The sidestream smoke treatment composition of the present invention comprises: an oxygen storage and oxidation catalyst for supplying a metal oxide which can be used in combination with an almost incombustible porous catalyst auxiliary particle. As disclosed by the applicant in U.S. Patent Application Serial No. 09/954,432, which is hereby incorporated by reference in its entirety in Control the sidestream smoke to an unexpected extent. It is known that certain types of catalyst materials and/or aids can cause ashing characteristics, such as, at some point, the appearance may be unacceptable due to fading, inability to form a thin layer, and inability to form a sheet. According to the invention, the composition can be reinforced, in particular to strengthen the catalyst and/or auxiliary to improve the ashing effect, to provide acceptable appearance, strength, color, integrity, reduce or eliminate sudden fire conditions, and not be thin Layers and similar situations that cannot be paged. The auxiliary may be any suitable virtually non-combustible, finely divided particulate material which does not affect the aroma and mouthfeel of the mainstream smoke and does not emanate any unwanted sidestream smoke vapor. The physical properties of the particulate matter are very stable at the high temperatures of the burning cigarette core. The adjuvant can have a low surface area, typically less than about 20 m2/g. The surface area of the high surface area aid is generally greater than 2 〇 m2 / g at this stage. The porosity aid has an average pore diameter of less than 100 nm (1, 〇〇〇人). Preferably, the average diameter of the aperture is less than 2 〇 nanometers (200 persons) and more preferably, the average diameter of the apertures is between 〇·51 〇 nanometers (5·100 Α). As for zeolite-based materials, the average pore diameter is between about 0.5 and 1.3 nm (5-13 persons). The average particle size of the auxiliary particles is less than about 3 microns, preferably 13 1270350 1 micron and up to about 5 microns. Non-combustible various types of porous clay, such as colloidal clay. It is also possible to use non-flammable materials of less than about 20 microns, more preferably sub-materials, which are commonly used to make scented clays or carbonaceous materials having a high surface area, including grinding of porous carbon fibers and granules. Different metal oxides and carbonates can be used, such as porous single-cube mineral-based materials, including oxidizing hammer, titanium dioxide, magnesium oxide, aluminum oxide, cerium oxide, tin oxide, iron oxide, manganese oxide, calcium carbonate, carbonic acid. Bismuth, magnesium carbonate and

Desirable zeolites include hydrophobic zeolites and slightly hydrophobic zeolites which have an affinity for hydrophobicity in the sidestream smoke with slightly hydrophobic organic components. The zeolitic material provides a highly porous structure that selectively adsorbs and absorbs components of the sidestream smoke. The highly porous structure generally contains a macroporous 14 1270350 structure between the particles, and has a microporous structure within the particles, which can open the macroporous structure. It is believed that the components trapped in the macroporous structure and the microporous structure can be converted into oxidized components in the presence of cerium oxide or other suitable oxidation catalyst at the high temperature of the burning cigarette, which can be continuously captured in the adsorbed component. It is released as an invisible gas, which is invisible or is an ideal low dose because it contains low tar and nicotine content.

Incorporate or coat the catalyst. The agent and the auxiliary use of other properties or use may not be such that the auxiliary materializing agent may be present in a form such as cerium nitrate or other dispersible form, for example, a cerium solid solution composed of cerium oxide hydrate Barium hydroxide, which may be added to a solution or a solid solution, and applied to a material or paper as a coating, which is converted into cerium oxide by burning the cigarette, and then used as a catalyst. The solution may be a low concentration of cerium oxide nitrate hydrate. For the purpose of illustrating the invention, the term catalyst herein includes any catalyst. A catalyst for cerium oxide can be used with an auxiliary. It is known that when used separately or when not in adjacent layers, the ability to control is greatly reduced. Although in some arrangements, the purpose of sidestream smoke can also be achieved. Preferably, the catalyst is substantially superior to the auxiliary material by mixing the catalyst particles with the auxiliary, contacting the auxiliary layer, applying the catalyst to the auxiliary or allowing the auxiliary to permeate the porous surface of the auxiliary. Sidestream Smoke Control In addition to the combined use of oxygen storage and supply of metal oxide oxide promoters, many other additional ingredients may be used. Additives to further enhance the treatment of sidestream smoke or to alter cigarettes. Such additional additives may be mixed with the treatment composition at any other location in the structure of the cigarette, provided that the auxiliary surface damages the ability of the treatment composition to treat sidestream smoke. The composition is formulated in different ways to achieve the purpose of blending and complementing. For example, the auxiliary material can be sprayed or dripped

17 !27〇35〇 Into the salt solution, such as hydrochloric acid chain or (4) liquid, to infiltrate the surface of the decorative auxiliary material. The oxidized layer can be prepared as a separate fine powder mixed with the auxiliary material. It is particularly desirable for the powder to have an average particle size of less than about 30 microns, more preferably less than about the job, and less than W to the right to ensure adequate mixing and blending of the materials. When the catalyst particle size and surface area are selected for general indication, the catalyst should have sufficient surface area to ensure that the catalyst is positioned to interact with the moving sidestream constituents. If the catalyst particles are properly dispersed, the catalyst should have a particle size greater than 3 Å to achieve the desired degree of oxidation of the sidestream smoke constituents.我们We have found that cerium oxide, especially high surface area oxidized enamel, is one of the few oxides that can exhibit the dual function of the invention, namely as an oxidation catalyst and auxiliary for oxygen storage and supply of metal oxides. Things. The porous oxide particles can achieve the desired surface area and particle size of the auxiliary. The cerium oxide is used as a catalyst for cigarette paper in the first usage amount and the fourth usage weight, and is used as an auxiliary in the treatment composition in the first use. The amount of cerium oxide used in accordance with the other total weight of the present invention corresponds to the amount used in the catalyst and the auxiliary. Alternatively, the high surface area oxide decoration can be used with an auxiliary such as zeolite or other high surface area metal oxide such as an oxidized junction. The lacquer may be formulated as a solution dispersion, such as a cerium oxide solution or the like: and applied to an adsorbent material such as buddha. The dried and oxidized enamel can then be fixed to the surface of the adsorbent material. When the cerium oxide particles 18 1270350 are fixed to the surface of the auxiliary, the surface of the ruthenium, for example, may have an average particle size of less than 1 μm. The relative amount of oxidized metal fixed to the surface of the Buddha may be between about 1% and 75% by weight, based on the total equivalents of cerium oxide and zeolite content. The relative amount of cerium oxide fixed to the surface of the zeolite is between about 5 Å/. It is preferable to use the total number of equivalents of cerium oxide and zeolite content as the basis. An ideal method for preparing a cerium oxide composite product fixed on the surface of a Buddha stone is described in the September 14, 2, GG, titled "Preparation of Metal Oxide Overwrought Microporous Materials"

The main method of the U.S. Patent Application Serial No. 60/3,878,878, which is hereby incorporated by reference, is hereby incorporated by reference. Although the above application provides a step of producing a catalytic cerium oxide coated zeolite particulate material comprising at least 1% by weight of cerium oxide coated on the outer surface of the zeolite particulate material, the total equivalent weight of cerium oxide and zeolite content. The number is the benchmark. The method generally comprises the following steps: (1) combining a certain amount of hydrocolloid dispersion of cerium oxide hydrate (ytterbium hydroxide) with a compatible zeolite granule material to form a slurry, which is determined

The hydrocolloid dispersion is sufficient to provide greater than 20% by weight of cerium oxide in the heat treatment of each step (ii), the zeolite particulate material having an average pore size of less than 20 A, the hydrocolloid dispersion having at least 2 Torr The pore size of the person is such that the hydrocolloid dispersion is placed on the outer surface of the zeolite; and (11) the slurry is first heat treated at a temperature below about 200 ° C, and the person is at a temperature of about 400 C south. Heating is carried out to fix the obtained cerium oxide on the outer surface of the zeolite particulate material to provide a large particle flowing from 19 1270350. Combinations of certain treatment compositions can result in an unacceptable ashing appearance. Unacceptable ashing appearances include the inability to form thin layers, inability to form sheets, gray, oily appearance and color. It has been thought in the past that various improved ashing agents can be added to cigarette paper to improve the appearance of ashing. Such improved ashing agents include metal oxides or carbonates such as zirconia, titania, magnesia, alumina, oxygen

Antimony, tin oxide, iron oxide, manganese oxide, calcium carbonate, zirconium carbonate, magnesium carbonate and mixtures thereof. It is known that in order to improve the ashing appearance it may be desirable to modify the treatment composition. Such improvements include the selection of a specific chemical or physical form of oxygen supply/oxygen storage catalyst and/or a particular type of auxiliary. In order to make the color of the ash approach white or gray instead of deep coal black, it is known that the zeolite in the auxiliary can be appropriately reduced.

This is achieved by the amount of material at the bottom. The amount of the fossil-based material in the reduced auxiliary material is preferably less than 35% by weight, more preferably less than 25% by weight, and most preferably less than 15%. (The weight ratio can also be added to other fillers to compensate for the reduced amount of Foshan m auxiliary (4). Suitable metal oxide substitutes include zirconia, tin oxide, = titanium oxide, magnesium oxide, #, low surface area Cerium oxide, calcium carbonate, and mixtures thereof. Preferably, a low or high surface area cerium/lanthanum mixed oxide is used as a solid. Such an auxiliary material can form a high surface area by (4) and (4) money, drying, and coal roasting. In the crystal structure, the ratio of 'oxidation # to yttrium oxide can be between 5:95 and 95:5. Alternatively, the ratio can be between 25:75. Up to 75:25 The high surface area physical form of this 20 1270350 material is also catalytically active, thus providing oxygen storage and supply properties, wherein the oxidized error system is used as an aid to the oxidized quinone. Cerium oxide can give a better ash For example, a cerium oxide can be deposited on a high surface area solution of high surface area cerium oxide, cerium oxide/zirconia (as in the foregoing ratio), and oxidized #hydrate can be deposited on high surface area #/zirconia; Drying the oxidized hydrate on a high surface area cerium oxide particle. In addition, the foregoing noble metal or transition metal oxidation catalyst may also be combined with a cerium-based material (for example, platinum, palladium, tin oxide, iron oxide, and Mixtures such as platinum/tin oxide, platinum/iron oxide/tin oxide, tin oxide/zirconia/yttria, and the like are used together. It is also known that the carbonate word can also improve the appearance of ashing. As described above, the composition is treated. Incorporating or coating on a packaged cigarette paper, which is the only paper that wraps the tobacco rod. As mentioned above, one of the ways to improve the appearance of ashing is to reduce the amount of adsorptive aids such as Buddha stone, and Substituting a selected metal oxide. Alternatively, for a single package of cigarette paper incorporated into the treatment composition, coating a layer of calcium carbonate on the outer surface of the packaged cigarette paper can greatly improve the ash Appearance ° Regarding the fact that the carbonated plant can greatly improve the appearance of ash, it is quite surprising 'perhaps because calcium carbonate can be chemically or physically combined with components other than the sidestream smoke treatment composition to produce a more uniform Light gray to gray ash furnace. Calcium carbonate can be mixed with a suitable binder to form a slurry on the cigarette paper. Suitable binders include those commonly used to coat calcium carbonate with 21 l27 〇 35 〇 Paper materials such as polyvinyl alcohol, starch, CMC, casein, bound clay, and other acceptable binders or adhesives. The unexpected activity of the sidestream smoke treatment composition allows it to be used on a variety of porous cigarette papers. It is known that the hard composition does not necessarily need to be used on cigarette paper having a high porosity, and the paper having a low porosity of about 5 gram units can be used for a paper having a high porosity of about 1 gram of the unit. Be applicable. Preferably, the porosity is generally less than about 200 grams per unit, most preferably between about 5 and 30 grams per unit. The cigarette paper used may be two or more layers. The paper can be used as a wrapper for the outermost layer of cigarettes, wrapped around traditional cigarette paper. Depending on the porosity, some combinations of catalysts and aids may work better than other combinations. The composition can be simply sprayed on one or both sides of the cigarette paper and adsorbed by the smoke. As shown in Fig. 1, the paper 10 is transported in the direction of the arrow 12. The treatment composition 14 is sprayed onto the paper 10 in the form of a slurry by means of a nozzle 16 to provide a coating 18 which is dried on the paper. Alternatively, the composition may be extruded into the surface of the paper in the form of a film which may be one or more layers. As shown in Fig. 2, the film coater 2 applies a film 22 to the sheet 1 and conveys it in the direction of the arrow 12. The film is dried to provide a coating 24 on the paper 10. After such an arrangement, it was surprisingly found that the sidestream smoke visible to the naked eye from burning the smog almost completely disappeared. The treatment composition can be applied to a conventional cigarette by application to a conventional cigarette paper. The coating can also be applied by a roller applicator 26, as shown in Figure 3. The treatment composition 14 is supplied to the drum 30 in a thin layer 28. The trimming blade 32 determines the thickness of the thin layer 34 to be applied to the paper 10, which is transported in the direction of the arrow 12 22 1270350. The thin layer is then dried to form a coating 36 on the paper 10. The treatment composition can also penetrate into the composition of the paper. The infiltration can be carried out using the drum 24 in Fig. 4, and the sheet 1 having the thin layer 36 is passed through the pressure rolls 38 and 40 in the direction of the arrow 12, which can laminate the substance of the composition into the paper 10 so that The ingredients in the treatment composition penetrate into the paper. Those skilled in the art will appreciate that other different coating methods, including transfer coating methods, can also be used to prepare the treatment materials of the present invention. In the transfer coating process, the coating composition can be transferred from the MylarTM plate to the surface of the cigarette paper using a MylarTM plate or other suitable plate. Such a transfer coating can be used when the physical strength characteristics of paper or the like are not suitable for use in a roll coating composition. Another alternative is to incorporate the treatment composition into the paper process. The composition can be introduced into the pulp in a slurry form. Referring to Figure 5, the treatment composition in the paper cassette 42 is agitated in a tank 46 with a stirrer 44 to form a package. The slurry is transferred to a moving conveyor belt 5 by a conventional paper-making method to form a thin layer 48 to form a cigarette paper 52. Thus, the treatment composition can be incorporated into the final paper product. Another alternative is to sandwich the treatment composition between the layers of paper to form a double layer of cigarette paper wrapped around the tobacco rod. For example, the composition can be sprayed on the inside of the outer paper or on the outer side of the inner paper by means as in Fig. 1. Once the two layers of paper are used in a tobacco rod, the composition can be sandwiched between two layers of cigarette paper in a thin layer. Each layer of cigarette paper can have half the thickness of a conventional cigarette paper, so that the double-layered web does not increase the overall diameter of the cigarette and can be completed by the cigarette maker 23 1270350. Referring to Fig. 6, the cigarette should be wrapped around a cigarette paper 10, and the outer side of the cigarette paper 10 is covered with a coating layer of the opposite layer 18, as shown in Fig. 7, the coating layer 18 is also It can be applied to the inner side surface of the tobacco sheet 1 条 / / / / / / / 。. An alternative is shown in Figure 8 and as previously described, the cover 18 is between the cigarette papers 56 and 58. The papers 56 and 58 and the interlaminar crucible therebetween can form a separate cigarette wrapper for use above the tobacco rod. A further alternative is shown in Figure 9 wherein the tobacco rod 54 is covered with a conventional cigarette paper 6 。. Covered on the conventional cigarette paper 60 is a cigarette paper 52 as shown in Fig. 5, which incorporates a treatment composition therein. The tobacco paper 52 incorporating the treatment composition therein can also be used directly on the tobacco rod 54.

Another embodiment of the present invention is that various combinations of sidestream smoke treatment paper can be used in a two-layer packaging paper form, for example, Figure 7 has a coated paper that can be used as an inner layer paper, and then another different type. Paper (can be a traditional cigarette paper) as an outer layer of double-layered paper. The inner layer paper may also be a cigarette paper incorporating the treatment composition therein, as shown in Fig. 9. The inner layer paper can be designed to reduce sidestream smoke by incorporating all of the necessary ingredients in the composition, such as an oxidation catalyst for the metal oxides stored and supplied by the oxygen, and a non-flammable auxiliary for the catalyst. Preferred examples of such compositions include a high surface area cerium/lanthanum mixed oxide and zeolite, and optionally an oxidation catalyst such as platinum or palladium. In a two-layer packaging system, the amount of zeolite may exceed 30% and may range from 50% to 60% by weight. The outer layer of the double layer package can have a different composition and can be used by 24 1270350

Designed to provide improved ashing effects to achieve desired characteristics. For example, the outer paper can be designed to not only enhance the ashing appearance, but also improve the burning rate of the cigarette and minimize the spark of sudden ignition during ignition or pumping (if not completely eliminated). The outer paper may comprise a metal oxide such as, for example, a low surface area oxidized finish, a high surface area oxidized oxidized/oxidized salt solution, indene, cerium oxide, titanium dioxide, tin oxide, and the like. In addition, the oxidized hydrazine can be applied to the outer paper metal oxide to ensure that sufficient oxygen is available to support the combustion of the outer paper. This two-layer paper can be used to effectively control sidestream smoke visible to the naked eye when combined into a two-layer system. The uniform burning of the adjacent paper produces the desired ash' and the outer paper allows the highly active oxygen supply to not suddenly ignite or minimize or even completely eliminate the ignition.

The double wrap paper of the present invention is characterized by a resilient design for low sidestream cigarettes. Each individual sheet of double layer paper may have a particular treatment composition embedded therein, overlaid or incorporated therein. Alternatively, the paper having the treatment composition incorporated therein may be coated with a layer of the same or different treatment composition to further enhance the control of the sidestream smoke and/or improve the ashing effect. To demonstrate the design flexibility of low sidestream smoke, exemplary treatment compositions for use on inner or outer paper are as follows: Outer paper (i) High surface area cerium oxide/oxidized hammer (75: 25) solid solution plus Low surface area cerium oxide; (ii) high surface area aluminum coated with hydrazine hydrate; (iii) low surface area cerium oxide coated with cerium hydrate; 25 1270350 (iv) high surface area zirconia, Topped with hydrazine hydrate; (V) high surface area cerium oxide/zirconia (25:75) solid solution. Inner layer paper (i) high surface area cerium oxide/zirconia (75:25) solid solution reinforced with palladium catalyst, plus zeolite reinforced with palladium catalyst; (ii) high surface area cerium oxide/oxidized hammer (75: 25) a solid solution plus a zeolite reinforced with a palladium catalyst; (iii) a high surface area cerium oxide/oxidized hammer (75:25) solid solution plus zeolite, wherein the cerium oxide/cerium oxide is strengthened with a palladium catalyst; Iv) High surface area cerium/zirconium mixed oxide (75:25) solid solution plus zeolite, wherein the cerium/lanthanum mixed oxide is reinforced with platinum and tin catalysts. The various compositions of these inner and outer layers can be used in combination in various ways to provide control of the sidestream smoke and to improve the ashing effect. The preferred combination is a combination of a high surface area cerium oxide/yttria (75:25) solid solution for the outer paper and a low surface area cerium oxide. The preferred treatment composition for the inner layer paper is a high surface area oxidized/oxidized (75:25) solid solution reinforced with a palladium catalyst plus a zeolite reinforced with a palladium catalyst. For the dry weight of the outer layer of paper, the coating formulation has a 25% high surface area cerium oxide/oxidized solid solution and 75% low surface area zirconia. In terms of dry weight of the inner layer of paper, it has about 44% high surface area cerium oxide/yttria solid solution and %% 26 1270350 buddha, both of which are strengthened. Those skilled in the art will appreciate that the foregoing methods of providing a low sidestream smoking composition in a cigarette or on a desired cigarette paper may vary depending on the composition and the number of wrappers on the tobacco rod. For example, two or more layers of paper, or both sides of the paper, can be used to reduce the load on one side of the paper, making coating applications easier. In the above-mentioned combination, it was found that the sidestream smoke visible to the naked eye was almost completely removed. At the same time, cigarette papers also exhibit traditional ashing results. It is particularly surprising that simply applying the composition of the invention to the exterior of the cigarette paper can almost completely remove or reduce the visible sidestream smoke to an undetectable The amount.

Depending on the composition used and the cigarette to be used, various process aids and mixtures thereof may be required to facilitate the particular application of the treatment composition. Such process aids include sheet materials such as polyvinyl acetate, starch, carboxymethyl cellulose. (CMC), casein and other forms of acceptable adhesives, different forms of binding clay, inert filter media, brighteners, viscosity modifiers, inert fiber materials such as hammer fibers and zirconium/niobium fibers as of September 13, 2001 U.S. Patent Application Serial No. 60/31,614, the disclosure of which is incorporated herein by reference. Penetrants can also be used to bring the composition into a non-flammable substance. The composition can also be diluted with a suitable diluent such as water to form a slurry which can be spray coated, roller blind coated, air knife coated, rod coated, pad coated, printed coated , sizing extrusion coating, roller coating, transfer technique coating and the like are applied to conventional cigarette paper. 27 1270350 Preferably, the amount of the treatment composition on the cigarette paper, wrapper or the like is between 2.5 g/m2 and about 125 g/m2, preferably between 2.5 g/m2. To about ι〇〇g/m2. The paper may contain from about 10% to about 500% by weight of the treatment composition, preferably from about 10% to about 40%, by weight of the treatment composition. These amounts are in the form of a single sheet of paper. Those skilled in the art will appreciate that the total weight described herein can also be used in two or more multi-ply paper systems.

The reduced sidestream composition is generally used in the form of a slurry of the composition, and the dry composition can be used in the form of a slurry which will be used as a paper coating, incorporated into paper or embedded in paper. Depending on the application. For example, the incorporated formulation may comprise from 1% to 33% by weight of the base catalyst, from 20% to 62% of the auxiliary and from 10% to 75% of the improved ashering agent. Another way is to include 10% to 25% by weight of the ruthenium-based catalyst, 40% to 55% of the auxiliary and 2% to 50% of the zeolite' Auxiliary.

The slurry can be incorporated into the papermaking process during the papermaking process or applied to the paper by a different coating method or can be infiltrated into the paper material by different infiltration methods, as previously described.
