The present invention relates to a cigarette filter and the cigarette filter.

The LEVEL of TECHNOLOGY

Filter cigarette created, in particular, to soften the taste when Smoking. Cigarette filter contains the main trunk formed from a rod of tobacco filler, such as tobacco bag, wrapped around the circumference of the cigarette paper and a filter attached to one end of the main trunk of the cigarette. The filter has at least one filter plug. In the filter blank filter material is located in a cylindrical housing formed of wrappers (wrappers of filter plugs), having the form of a cylindrical configuration (generally rounded configuration of the cylinder). Filter fasten to one end of the main trunk of the cigarette through the tipping paper.

The hardness of the filter cigarette with the filter is the option of choice cigarette smokers. Most are sold on the market today cigarettes with filter use of pulp and acetate fiber bundle (tow) as filter material (hereinafter in this application is also referred to as pulp-acetate filter). Because satisfactory hardness of the filter cannot be obtained through one of pulp and acetate fiber, it is mixed plasticizer (e.g., triacetin) to make Phi is TRU hardness. It is known that the number of triacetin added to the pulp acetate filter, now sold in the market of cigarettes with filter is in the range from 5 to 10 wt.% in the calculation of the amount of cellulose acetate.

Some smokers are satisfied with the hardness of the filter is given by adding the above triacetine, but some smokers love more solid filters.

It is known that in respect of pulp and acetate filter its hardness can be increased by increasing the amount of added plasticizer. However, when the amount added of triacetin increases to some degree or higher, triacetin is hydrolysed with formation through this acetic acid. So must be a problem that the inside of a cigarette package is filled with the smell of acetic acid. In addition, when using a carbon filter, you should experience a problem that triacetin is absorbed at an angle, resulting in a function of coal (absorption components of smoke) cannot be implemented in full.

Cigarettes with a filter it is desirable that their ventilation ratio was high in order to ensure the possibility of receiving external air to a higher dilution of inhaled by the smoker smoke.

Cigarette filter vasocongestion ratio, known as cigarette filter with a hollow, disclosed in WO 00/00047. This cigarette filter contains, for example, two filter plugs, both of which are wrapped porous or non-porous wrapper filter plugs, with two filter plugs are connected to each other by forming non-porous paper. This filter is inserted into the tobacco rod by tipping ("double") paper. To get high ventilation ratio, the wrapper of the filter plugs and forming the paper supply mechanically punched relatively large air holes, and tipping paper supply relatively small vent hole punched laser. Ventilation openings shall cause such problems as increase in the cost of production of cigarettes, lowering the processability of a variety of cigarette products, including cigarettes with low tar and the like, at a low stability of product quality. These issues are also noted in published application Japan 2004-516814, revealing a similar filter with deepening.

In WO 00/00047 and published application Japan 2004-516814 there is no direct reference to the hardness of the filter.

The preferred embodiment of the invention

Cigarette filter according to the invention comprises a so-called Monomeric filter formed from a single filter stub, and the so-called multi-segment filter containing many filter caps, including (the) near the filter cover and (very) far the filter cap. Each of the sets of filter plugs comprises in General a cylindrical body formed of the wrappers of filter plugs, which is attached to a cylindrical shape, and the filter material located in the cylindrical housing. Illustratively, filter cap, includes filter material in the wrapper for the filter material. In multi-segment filter set filter plugs forming wrapped paper to connect them with each other. In the present invention the expression "close" or "located on" mean respectively "BL the same" or "more" from the tobacco rod, i.e. in the direction of the flow of tobacco smoke, is drawn by the smoker through the cigarette.

In the present invention, the wrapper of the filter plugs Monomeric filter formed from high-strength and high-permeability paper. Also in the multi-segment filter according to the invention, the wrapper of the filter stubs for at least one of the filter caps and/or forming the paper formed from high-strength and high-permeability paper.

High-strength and high-permeability paper for use in the present invention has a longitudinal stiffness of paper (inflexibility in the longitudinal direction)of $ 30 or more when measured in accordance with JIS P8143, and breathability, component 1000 or more CORESTA units. Preferably, high-strength and high-permeability paper has a longitudinal stiffness of from 30 to 400 and the permeability of 1000 to 30000 CORESTA units.

Examples of high strength and high permeability of securities for use in the present invention (indicated by the symbols S1 through S4) are shown in Table. The table also includes used in most cases currently, the wrapper for the porous filter plugs with high permeability (plain wrapper filter plugs denoted by symbol R).

Will be described a case where the filtering material used pulp-acetate in ognisty harness. As mentioned above, the usual practice is to add a plasticizer such as triacetin in filter in an amount corresponding to from 5 to 10 wt.% by weight of pulp and acetate fiber, in order to give the filter a given hardness. However, when using high-strength and high-permeability paper according to the invention, the same hardness of the filter can be obtained even by adding a plasticizer in an amount corresponding to less than 5% (including 0%) of the weight of pulp and acetate fiber. Needless to say that, when the plasticizer is added to pulp and acetate fiber in the same amount corresponding to from 5 to 10% of its weight, and up to the present time, can be obtained hardness higher than the normal filter.

Based on the results to date information it is clear that the addition of triacetin a quantity of more than 12 wt.%, will dissolve pulp and acetate fiber and will cause the problem of odor of acetic acid, accompanying the decomposition of triacetin. Accordingly, the upper threshold value of hardness of the conventional filter is achieved without the occurrence of these problems is the hardness corresponding to the addition of 12 wt.% triacetin. However, when using high-strength and high-permeability paper according to the invention with the addition of 2 wt.% triacetin, you can achieve a hardness in excess of the normal upper threshold values of hardness. That is, the present invention can be applied to pulp acetate filter with triacetin added in a quantity in excess of 10 wt.%, but not more than 12 wt.%.

The filter material of the cigarette filter according to the invention is not limited to pulp and acetate fiber. For example, in this area it is known the use of a filter obtained through profiling of non-woven material, and filter (paper filter)obtained by profiling the paper being processed by keperawanan), which has not increased hardness agents (agents that increase the hardness of the filter), such as a hardener, including plasticizer, such as triacetin, and binders added to bind the filter material together (for example, polyvinyl alcohol, polyvinyl acetate, polyethylene glycol, dimethylphthalate, diethylphthalate etc). Data filtering materials can also be used in the present invention.

The filter material does not contain any increasing hardness agent, it is difficult to achieve the hardness of the filter is equivalent to the hardness pulp acetate filter having added thereto triacetin. However, the hardness of the filter, equivalent or above, who eat hardness pulp acetate filter, having added thereto triacetin can be obtained through the use of high-strength and high-permeability paper according to the invention.

The filter includes a filter material that does not contain any increasing hardness agent, gives an additional advantage, when used in a cigarette filter having any of the flavors (such as menthol, lemon, peppermint oil or peppermint oil curly; ester such as ethyl acetate, ethyl butyrate or ethylbenzoic; alcohol, such as linalool, nerol or geraniol; phenol, such as anethole; aldehydes, such as cinnamaldehyde or vanilla; lactone and piratin) together with triacetin, absorbed in pulp and acetate fiber.

For example, in a General menthol cigarette menthol mix in the shredded tobacco and inserting a pulp-acetate filter comprising triacetin. However, in common pulp-acetate filter menthol contained in the cigarette together with triacetin, over time, absorbed in the pulp-acetate filter. Menthol, absorbed in pulp and acetate filter, is not tolerated in inhaled by the smoker smoke in the Smoking process. Accordingly, it is known that, even when menthol is present in the cigarette, shipping menthol in inhaled by the smoker smoke over time smart who agrees, in accordance with the sorption of menthol in the filter. In contrast, the filter material such as filter paper containing no plasticizer, curing agent or binder, sorption of menthol in the filter over time does not occur unlike pulp acetate filter containing a plasticizer, and menthol remains in the powdered tobacco. As a result, even when the amount of menthol in the cigarette is the same amount of menthol delivered from shredded tobacco in the Smoking process, more, thereby ensuring the delivery of menthol higher than when using pulp-acetate filter containing triacetin. In addition, since the filter avoid adsorption of menthol, shipping menthol in inhaled by the smoker smoke is stable over time. Similar effects can be caused when the flavor, such as menthol, are added directly to the filter or when it is added to the paper from plate aluminum inside a cigarette pack. In addition, these effects can be caused, even when using pulp and acetate fibers reduce the additional amount of triacetin, causing the sorption, or when as increasing the hardness of the agent used substance are less likely to contribute to sorption than triacetin (for example, polyvinyl alcohol, polyvinyl acetate, Paul is ethylene glycol, epoxy resin and the like).

Needless to say that in the multi-segment filter filter plug formed from a filter material that does not contain any increasing hardness agent, may be combined with a filter plug formed from a pulp-acetate filter.

In addition, the filter according to the invention may include a filter plug having added thereto particles of activated carbon (charcoal). In Monomeric filter particles of activated carbon can be added to a single filter cap. In monosegmental the filter, as a rule, particles of activated carbon is added to the filter cover, located to the farthest filter plugs.

In addition, the filter according to the invention may have a filter structure with a cavity, which is described in WO 00/00047 and published application Japan 2004-516814. Illustrative, in this case, when the application is based on Monomeric filter, cylindrical body only filter plugs lasts located on the end surface of the filter material in order to ensure that the area of the recess. When the application is based on a multi-segment filter, forming the paper proceeds from the further end surface located far filtration plugs for that is about, to ensure that the area of the recess.

The present invention will be described below with reference to the drawings. The same elements are denoted by identical positions on all drawings.

Figure 1 shows the partially expanded schematic view in perspective cigarettes 100 Monomeric filter.

The 100 cigarette filter includes a core barrel 110 cigarettes and the filter plug 120 at one end of the main shaft 110 cigarettes. The main shaft 110 of the filter cigarette is identical to conventional cigarettes and includes a tobacco rod and cigarette paper, which is wrapped around the circumference of the tobacco rod (not shown neither). The tobacco rod formed from shredded tobacco filler, such as tobacco bag. The filter cap 120 includes a cylindrical housing 122 of the wrappers of filter plugs, which has a cylindrical shape 121, and the filter material 123, located in the cylindrical housing 122. The main shaft 110 cigarettes and the filter plug 120 are connected to each other by means of tipping paper 130 in such a way that their end faces are connected to each other in the same way, as recognized in the cigarette filter. Tipping paper 130 can be provided with ventilation holes 131.

In the cigarette filter, shown in Fig. 1, as a wrapper 121 filter Zahl is the loud use of high-strength and high-permeability paper according to the invention.

Fig. 2 is a partially expanded schematic view in perspective of 200 cigarettes with filter, equipped with a two-segment filter as an example of the multi-segment filter.

In the cigarette 200 with a two-segment filter filter 210 is inserted into one end of the main shaft 110 cigarettes. The two-piece filter 210 includes two filter plugs 220 and 230. Located closer to the tobacco rod, the filter cover 220 includes a cylindrical housing 222 of the wrappers of filter plugs, which has a cylindrical shape 221, and the filter material 223 located in the cylindrical housing 222. Similarly, located on the filter cap 230 includes a cylindrical body 232 of the wrappers of filter plugs, which has a cylindrical shape 231, and the filter material 233 located in the cylindrical housing 232. Two filter plugs 220 and 230 are connected to each other by forming paper 240 so that their end surfaces joined to each other. The main shaft 110 of cigarettes and two-segment filter 210 are connected to each other by means of tipping paper 130 so that their end surfaces joined to each other in the same way as regular cigarettes with filter.

In the cigarette filter, shown in Fig. 2, one of the two or both of the wrapper 22 and 231 of the filter plugs can be formed of high-strength and high-permeability paper according to the invention.

Since most smokers usually placed located on the filter cap 230 in the mouth, the hardness of the filter is often felt lips. Consequently, when the wrapper 231 filter plugs located on the filter plugs 230 are formed from high-strength and high-permeability paper according to the invention, even if the wrappers of filter plugs other filter plugs are not formed from high-strength and high-permeability paper, smokers can feel the preservation or increase the hardness of the filter. In addition, smokers are holding a cigarette with his fingers in the process area, so that the hardness of the filter can feel with your fingers. In this case, it is desirable to use high-strength and high-permeability paper according to the invention in a wrapper 221 filter plugs 220 next to the shredded tobacco. Needless to say that when a high-strength and high-permeability paper in the present invention are used in both wrappers 221 and 231 of the filter plugs, the hardness of the filter can be felt lips and fingers. In addition, when it is expected to maintain or increase the hardness of the entire filter to the cigarette, equipped with a multi-segment filter, the goal can be achieved through the use of high-strength and high-permeability paper according to the invention in fil is rojalnoj forming paper 240 of the multi-segment filter. In this case, both wrappers 221 and 231 of the filter plugs can be formed from any of the usual wrappers of filter plugs (rigidity 10-15, breathability 70-30000 CORESTA units, the thickness of 30-80 μm and baseline weight 15-27 g/m2). When it is desirable to further increase the rigidity of the filter, this can be achieved not only through the use of high-strength and high-permeability paper wrapper 221 and/or 231 of the filter caps, but also through the use of high-strength and high-permeability paper according to the invention in forming the paper 240, namely through the dual use of high-strength and high-permeability paper.

Fig. 3 is a partially expanded schematic view in perspective of 300 cigarettes with filter provided with the Monomeric filter with deepening.

Cigarette 300, equipped with a filter with a cavity, includes a main shaft 110 cigarettes and the filter plug 320 provided at one end of the main shaft 110 cigarettes. Filter cap 320 includes a cylindrical body 322 wrappers of filter plugs, which is attached to cylindrical form 321, and the filter material 323, placed in a cylindrical housing 322. Cylindrical body 122 extends from located on the end surface of the filter material 323 in order to ensure that the area of the recess 324. The main is twol 110 cigarette and filter plug 320 are connected to each other by means of tipping paper 130 thus, so they end surface joined to each other in the same way as regular cigarettes with filter. Tipping paper 130 can be provided with ventilation holes 131.

In the cigarette filter, shown in Fig. 3, high-strength and high-permeability paper according to the invention is used as a wrapper 321 filter plugs.

EXAMPLE

The present invention will be described below with reference to the following examples.

Example 1

The filter caps were obtained according to standard methods as wrappers of filter plugs types of securities listed in the Table above. Used filter material, consisting of normal pulp and acetate fiber tow having added to it triacetin in an amount corresponding to 6 wt.% by weight of pulp and acetate fiber tow. Each of the filter caps had a circumference equal to 24.5 mm, and a length of 25 mm, Each of the wrappers of filter plugs to cover the circumference of the filter material in exact proportion. Measured hardness of each of the obtained filters.

Of course, the hardness of each of the filters should be measured in the condition of the filter inserted in the cigarette. However, due to problems associated with measuring instruments, it is difficult to measure the hardness of each and the filters in the filter state, inserted in a cigarette. As a consequence, the hardness of each of the filters was measured in the form of filter plugs before inserting into the cigarette (hereinafter in this application, the hardness of the filter was measured by the same measuring method).

The hardness of the filter was measured using NFQA (instrument for measuring the quality of a filter), made JT TOSHI. The result is shown in Fig. 4. The hardness of the filter was calculated from the stretching that occurs on the filter when applying a given load. Accordingly, the lower the tension, the greater the hardness of the filter. Thus, as shown in Fig. 4, the smaller the value of hardness of the filter, the harder the filter.

It Is Evident From Fig. 4 it is clear that the hardness of each filter of the filter plugs supplied with high strength and high permeability securities S1-S4 according to the invention, increases above the hardness of the filter plugs supplied commonly used at present, wrap P filter plugs. All the filter caps, equipped with high strength and high permeability securities S1-S4 according to the invention, exhibited a permeability equal to 1000 CORESTA units or above. In addition, could be applicable to high-strength paper S4, demonstrating the permeability, equivalent permeability commonly used at present, wrap P filter plugs.

In the later use of high-strength and high-permeability paper according to the invention makes it possible not only to achieve the preservation or enhancement of the hardness of the filter, but also to avoid the problems of the prior art of ventilation holes, namely the increase in the cost of manufacturing cigarettes, low adaptability to a variety of cigarette products, including cigarettes with low tar and the like, and low stability of product quality.

Example 2

The filter plugs of the same size as in Example 1, was obtained using conventional wrapper P filter plugs and high-strength and high-permeability paper S4 indicated in the table. The filter material was represented by the same traditional harness from pulp and acetate fiber as in Example 1, but changed the number of triacetin added in tow (number of equivalent 0-12 wt.% by weight of pulp and acetate fiber). The hardness of each of the obtained filter plugs was measured in the same manner as in Example 1. The results are shown in Fig. 5. In Fig. 5 lineandshows the results of using the wrapper P filter plugs and linebshows the results of the use of high-strength and high-permeability paper S4.

It Is Evident From Fig. 5 it is clear that, when using high-strength and high-permeability paper S4 regardless of the amount added of triacetin, the hardness of the filter is increased higher than the hardness of the filter plugs using conventional wrapper P filtering is a stub.

As mentioned above, in the present cigarettes triacetin is added to the filter in a quantity of 5 to 10 wt.% the weight of the filter material. However, it is seen that, when using high-strength and high-permeability paper S4, the hardness of the filter can be increased without increasing the number of triacetin.

In the examples, where the number of triacetin less, found that shows the hardness of the filter, when using the conventional wrapper P filter stub, and the number of triacetin approximately 6 wt.%, can be achieved through the use of triacetin in the amount of approximately 3 wt.%, when using high-strength and high-permeability paper S4. As a result, even when the number of triacetin less can be achieved hardness equivalent to the hardness of the currently available filter through the use of high-strength and high-permeability paper S4.

Example 3

The so-called paper filter plugs were obtained using the types of securities listed in the Table. Used filter material was a low-grade crepe paper. The configuration of each of the obtained filter plugs was the same as in Example 1. All filter caps showed resistance to air on the Oka, equal to 350 mm H2O/120 mm, the Hardness of each of the obtained filter plugs was measured in the same manner as in Example 1. The results are shown in Fig. 6.

It Is Evident From Fig. 6 it is clear that the paper filter plugs, wrapped high strength and high permeability securities according to the invention, demonstrate the same satisfactorily increased hardness values, as the values of pulp and acetate filter plugs of Example 1, the wrapped high strength and high permeability securities according to the invention. In addition, the increased hardness of the filter to a level equivalent to the hardness of the filter shown pulp acetate filter with triacetin added in a quantity equal to 6 wt.%, can be achieved through the application of the invention.

Example 4

Filter cigarette was obtained by inserting each of the pulp-acetate filter plugs obtained using conventional wrapper P filter plugs in Example 1, and a paper filter plugs obtained with the use of high-strength and high-permeability paper S4 in Example 3, the trunk cigarettes by tipping paper. Menthol was added in a quantity equal to 3.0 mg per cigarette, shredded tobacco is the main trunk of the cigarette. The obtained filter cigarette kept in an air-conditioned bar is the area at 22°C and relative humidity equal to 60%, since the end workmanship for a period of 12 weeks. The existing ratio of menthol in the powdered tobacco and filter material during storage was measured by the method described below. The results are shown in Fig. 7 and Fig. 8. Fig. 7 shows the results relative to the pulp-acetate filter plugs. Fig. 8 shows the results regarding the paper filter plugs. In Fig. 7 and Fig. 8 each of the shaded areas indicates the ratio of menthol in the filter material, and each of the pure plots shows the ratio of menthol in the powdered tobacco.

In respect of both filtered cigarettes during the above mentioned period storage shipping menthol in inhaled by the smoker smoke (ratio menthol/resin ratio (M/s)) was measured by the method described below. The results are shown in Fig. 9. In Fig. 9 lineandshows the results relative to cigarettes with filter paper and linebshows the results regarding cigarettes pulp-acetate filter.

The method of measuring the amount of menthol in the powdered tobacco and filter material

Each cigarette was shared on the site with shredded tobacco (including cigarette paper) and the plot of the filter.

After that, the plot with shredded tobacco was placed in methanol, vstrechi the Ali at room temperature for 40 minutes and allowed for the stationary state precisely within 24 hours. The mixture was again shaken for 40 minutes, and the supernatant was separated in the form of menthol extract.

On the other hand, the area of the filter was placed in methanol was shaken at room temperature for 40 minutes and allowed for the stationary state precisely within 24 hours. The supernatant was separated in the form of menthol extract.

Thus obtained menthol extracts were analyzed by gas chromatograph equipped with a hydrogen flame ionization detector (FID)detector. The amount of menthol was determined using the internal standard method. As internal standard used 1,3-butanediol.

The method of measuring the ratio menthol/resin

The resin contained in the composition of inhaled by the smoker to tobacco smoke, measured in accordance with ISO 3308 and 4387.

As for the menthol contained in the composition of inhaled by the smoker to tobacco smoke in accordance with ISO 4387 inhaled by a smoker, the smoke was arrested in Cambridge filter, and the Cambridge filter was placed in methanol and shaken at room temperature for 40 minutes. The supernatant was separated in the form of menthol extract. Thus obtained menthol extract was analyzed by gas chromatograph equipped with FID as detector. The amount of menthol is definitely the Lyali using the internal standard method. As internal standard used 1,3-butanediol.

The ratio menthol/resin ratio (M/s) was calculated from the values of the quantities of tar and menthol in inhaled by the smoker smoke, determined using the methods described above.

The results obtained confirm the move menthol out of phase with shredded tobacco in the area of the filter, when using the pulp-acetate filter. Therefore, it is clear that the delivery of menthol decreases over time. In contrast, when using a paper filter, menthol does not move in the filter and remain in the powdered tobacco. As a result, compared with the use of pulp-acetate filter not only stabilizes the delivery of menthol over time, but also can be achieved with high shipping menthol.

As is clear from the above that the use according to the invention makes it possible for menthol cigarettes, which, while maintaining the hardness of the filter shows a high ratio M/s, namely high shipping menthol, even when the filter material of paper used, not containing increasing the hardness of the agent.
