THE iNVENTION field

The The present invention relates to biodegradable filter cigarettes with two densities.

Especially The present invention relates to biodegradable filter cigarettes with two densities comprising two sections, a tobacco rod as well a tilting portion, which are connected to each other in the longitudinal direction.

State of technology

The currently Cigarettes available on the domestic and international market can be purchased in divided into two classes, namely cigarettes without filters (filterless cigarettes) and filter cigarettes. Become cigarettes manufactured in different diameter and length sizes. The costs of filterless cigarettes are considerably lower. These "filterless Pulling cigarettes " two types of smokers - "Bidi smokers who want to upgrade "and" filter cigarette smoker, for themselves cheaper cigarettes decide ".

The unfiltered cigarettes have over the entire length the cigarette tobacco with normal density. Often get loose tobacco particles in the mouth of the smoker, since there is no filter. The filterless Cigarette is due to the constant contact with the mouth of the Smoker often drenched at the fume. In addition, the cigarette loses due to the relatively loose packing density of tobacco and due to the loss of tobacco particles from the end, not being smoked, their stiffness.

filter cigarettes contain tobacco of normal density together with synthetic filters. The filter plug in a filter cigarette includes fibrous Material attached to a tobacco rod of normal density. The fibrous material may be cellulose, acetate fibers, polypropylene fibers or any other known type of synthetic fibrous material be. These filter cigarettes are not biodegradable and require special cigarette manufacturing equipment and besides, these are cigarettes more expensive than unfiltered cigarettes.

US Patent Application No. 09 / 988,828 teaches a filter cigarette with tobacco filter in which the tobacco rod is enclosed by a cigarette paper. The tobacco used is made without the use of rolled medium-cut stems and without reconstituted tobacco having a cutting width of 0.3 to 0.6 mm, and the filter has a tobacco packing density of 350 to 400 g / cm ³ .

The EP 1 250 854 A1 describes a pollutant-reduced cigarette comprising adding a hydrate of the double salt of ferric chloride to the tobacco and the cigarette filter which is to react with nicotine and form a salt that is not absorbed by the mucous membranes in the smoker's airway system The nicotine pen is minimized and the health of the smoker is improved.

The EP 1 032 282 describes a filter for tobacco products, in particular cigarettes, which is made of a fiber-cellulosic material which is produced by means of an air-laid method and spirally rolled.

The EP 1 032 283 describes a filter cigarette comprising a biodegradable filter and a tobacco rod surrounded by a cigarette paper, a fiber air-laid cellulose filter with a normal retention capacity, and a filter vent surface extending in a peripheral direction. The filter cigarette has the combination of features. The filter has a condensate retention capacity of 40 to 60%; the fiber-cellulose is not crimped, the nicotine / tobacco rod condensate yield ratio is between 0.6 and 0.9 (nicotine × 10 / condensate), the tobacco blend tobacco blend has a bulk density of 200-250 mg / ml, tobacco rod resistance is intermediate 45 and 65 mmW WS, when measured in a closed mold, the air permeability of the cigarette paper is 20 to 50 CORESTA units and the filter aeration rate is 15 to 50%.

WO 01/58290 A1 discloses a cigarette filter for easy removal of harmful materials such as nicotine and tar from cigarette smoke. During inhalation, the filter may filter out harmful ingredients such as nicotine and tar contained in the cigarette smoke via a front filter, a mugwort impregnated filter mesh, a diffusion body, a pine resin impregnated filter mesh, and then a backside filter. In addition, the filter comprising the mugwort and the pine resin is present It also helps the smoker to feel normal during inhalation, due to the aromatic properties of mugwort and pine resin impregnated into the filter meshes present in the filter.

WHERE 00/72706 discloses a filter cigarette with a tobacco filter.

The Filter of cigarettes used to filter out harmful Materials such as nicotine and tar are thought to be on one The end of the cigarette is ready. Such filters typically become divided into several species as follows: d. H. the conventional ones Filters of the cigarettes are structured according to their structure into a single filter consisting of an integrated filter, in a double filter, which is formed by linear arrangement of two filter segments, as well as in a multiple filter, the linear arrangement of a Variety of different types of filter segments is formed, divided. The filters are also based on the material of the filter in fiber filters, loaded with chemical granules filter, and carbon granules divided loaded filters. Enable in the prior art It fiber filters that contain harmful materials in the cigarette smoke just go through their fibrous matrix, which is why greater Effect can not be expected. However, fiber filters are, in particular those with carbon or chemical granules for removal nicotine and tar are particularly preferred as a filter for Cigarettes widely used.

traditionally, For example, a cigarette rod making machine includes a distributor, the fragmented particles of tobacco leaves, fragmented leaves reconstituted tobacco and / or fragments of artificial tobacco from a stream forming zone supplies, in which the particles form a continuous stream. One contains such current a surplus on fibrous material and is on its way with a conveyor belt after a sizing device or compensating device, which the surplus removed, converted into a continuous rod. The resulting Pole (also called filler) is then compressed and placed in a roll of cigarette paper or another suitable packaging material draped to with the paper roll to form a cigarette rod, leading to sections uniform length or more unit lengths is divided (eg by means of a conventional clipping method). The cigarettes thus obtained become the storage, a packaging machine or a filter placement machine fed. Certain types of filter rod sections will be similar Produce or can be produced, with the exception that the fibrous material, which makes the stream is a substance that certain, probably harmful Ingredients of tobacco smoke intercepts, though it's the rod-shaped Component of the filter mouthpiece forms in the filter cigarette.

The The object of the present invention is to give the smoker a filter cigarette to disposal to provide, which has a filter section, the biodegradable and significantly reduces the tar and nicotine elements and higher chloride levels having.

The The object of the present invention is to give the smoker a filter cigarette to disposal which is both cheap and environmentally friendly.

A Yet another object of the present invention is to provide a on natural Ways to provide biodegradable cigarettes that provide a smoke delivery profile which is comparable to that of a synthetic filter cigarette.

A Another object of the present invention is to provide satisfaction to ensure, which is comparable to that of a conventional filter cigarette without indeed to have a synthetic filter in the cigarette.

Short description of drawings

The 1 Figure 3 illustrates a two density cigarette with normally dense tobacco at one end and high density tobacco at the other end. The aspect ratio of normal and high density can be made to obtain the expected smoke output profile.

Detailed description the invention:

The present invention an improvement in the smoke delivery profile compared to normal synthetic filter cigarettes, and also leads to a considerable Reduction of tar and nicotine. Due to the high density tobacco At the mouth-side end is also the humidification of the tobacco, though This is put in the mouth avoided, as well as the entrance from loose tobacco particles in the mouth.

The Cigarette is 100% biodegradable and inexpensive since the conventional ones Machines can be used.

These Cigarette is smoked by the high density end and this high density Tobacco content becomes with porous Cork filter paper of various colors for identification purposes equipped so the consumer can recognize that the tipping part to take the cigarette in the mouth.

high density Tobacco sticks can using tobacco material such as cut and rolled Stems, assorted tobacco, reconstituted tobacco and tobacco dust with binders as well as various combinations of the above Materials or more natural Materials are produced.

The density of such a rod may be selected according to the individual product needs. Normally, the density is selected to be at least 280 mg / cm ³ . 1 shows that the tobacco or filler bar (1) is a tobacco blend wrapped in a cigarette paper at a pressure drop of 22 to 50 mm water column. The filler bar (1) is filled with a tobacco blend comprising 75 to 85% leaf material and 15 to 25% of the expanded stem fibers or cut and rolled stems. The sheet material is normally dense tobacco from 4 to 6 cm ³ / g at a rate of 12.5% oven volatiles, preferably 5 to 6 cm ³ / g at a rate of 12.5% oven volatiles. The tipping part (2) comprising cut and rolled stalk particles of expanded fibers having a density of at least 0.28 g / cm ³ , wrapped in porous paper of at least 100 mm water column. The expanded stem material has from 4 to 7 cm ³ / g at a rate of 12.5% oven volatile, preferably 6 to 7 cm ³ / g at a rate of 12.5% oven volatile. The pressure drop in the tobacco rod is 5 to 9 mm water column per mm filler end, while the pressure drop in the tip end is 3 to 4 mm water column per mm. The stalk part is the midrib of the tobacco plant leaf with a lower nicotine content and a higher chloride content.

normal and high density tobacco rods are used on cigarette making machines using plain cigarette paper as a wrap for the rod produced. The stalk of the tobacco leaf is at 30 for 10 to 20 minutes up to 40 ° C a conventional one Subjected to air conditioning process to quench the moisture evenly. The quenched stalk is through an air conditioning tunnel or through a smoothing device or a roller to smooth the stem. The stem then turns into small particles of size 30 cut to 180 cpi. The small particles are separated by a expansion-heated tunnel at a temperature of 100 to 103 ° C for a Period of 20 to 30 seconds cut. The particles will be then passed through a dryer and a sorter to cut and to obtain rolled stems (CRS). The CRS will be at room temperature cooled by storing in roll humidifier containers. The cooled cut and rolled stems are encapsulated in a filter wrap paper, to get the filter tip.

The Putties or Tobacco rods are made in the required length and then one Supplied mounting device, whose purpose is the normal and high-density tobacco filter dumps in relation to of 5: 1.

The Mounting device also cuts the high density bars into suitable pieces usually 4 to 6 pieces, called "plugs", however, other combinations are possible. After that, these "plugs" with the normal Tobacco rod assembled and with the filter paper suitable Width, size and color wrapped. The filter paper or the plug wrap can either normal or relatively highly porous be around the desired To give smoke emission values.

These specially made cigarette with two densities can provide a smoke profile that is comparable to any other usual Filter, as results from the test results.

Even though special embodiments of the present invention have been illustrated and described, Both other changes are obvious to the professionals and Modifications can be made are without departing from the scope of the invention as defined in the appended claims.

The following table shows a typical example of the properties of the tilting end:

The following table shows the properties of the filler or the tobacco rod:

It It is obvious that the humidity and the nicotine content are lower in the tipping end while the TRS and chloride content in the tipping end is greater compared to the filler end.

analytical Testing

It A series of analytical tests was carried out to determine the tar and nicotine content of filterless cigarettes, filter cigarettes and cigarettes compare two densities. The three analytical tables are as indicated below:

table 1 comprises three sub-tables, which are the density trend of filterless Micro cigarettes (Table 1A), filterless and regular filter cigarettes (Table 1B) and Kingsizemarken (Table 1C) show.

Tables 1A, 1B and 1C show the comparable tobacco density present in various cigarette brands with a standard length of 59 mm. The data are taken for two years, ie for the years 2000 and 2001. The data shows that the average density of tobacco in the case of unfiltered micromarkers (Table 1A), filter marks (Table 1B) and the Kingsizem brand (Table 1C) is between 232 mg / cm ³ and 264 mg / cm ³ .

The Table 2 contains the analytical data that compares Tar and nicotine in the filterless and cigarettes with two densities demonstrate. The analytical data show that the cigarettes with two Dense lower levels of tar and nicotine, by comparison to the filterless cigarettes of the same length.

The Table 3 shows the comparison of conventional filter cigarettes, that in the two-density cigarettes according to the present invention and the tar and nicotine yield obtained from unfiltered cigarettes. The table shows that the quality of the smoke delivery of the cigarette with two densities comparable to that of the filter cigarette. Of the Tar content of the smoke from the cigarette with two densities with one Circumference of 24.44 mm is slight higher than the tar content of the filter cigarette with a circumference of 24.46 mm.
