    A CIGARETTE FILTER, including a porous plug, enclosed in a wrapper, made impermeable to smoke and having longitudinal grooves of semicircular cross section open on one side, symmetrically located on its surface, characterized in that, in order to improve the taste of smoke when smoking a cigarette, the grooves on the surface are over They are located so that their open part is placed at the end of the filter, facing the mouth of the smoker, while the cross-sectional area of the grooves is 0.125-1,000% of the total g of the cross-sectional area of the filter, and the numbers The grooves range from 3 tons to 7.

    11, The invention relates to filters for cigarettes, in particular to filters with new ventilation means, as well as to cigarette filters having channels directed the flow of ventilating air to that end of the filter that is in the mouth of the smoker to be mixed with the outer surface. The invention also relates to highly ventilated cigarettes, in which a dm, passing into a filter, instantly disperses. Known cigarette f -1ltra, obes; baking air ventilation using means that communicate with the surrounding air to dilute the flow of tobacco smoke directly in filter 1. A cigarette filter is also known, which includes a porous plug which has been tied into a wrapper, is made impermeable to smoke and has longitudinal grooves of semicircular cross section open on one side, symmetrically located on its surface 2J. A disadvantage of the known filter is that it mixes smoke with air in the groove with air, which negatively affects the taste of the smoke. The purpose of the invention is to improve the taste of smoke when smoking a cigarette. This goal is achieved by the fact that in a cigarette filter containing a porous stopper sealed in a wrapper made impermeable to and having longitudinal open grooves of semicircular cross section open on one side, symmetrically located on its surface, grooves on the surface of the wrapper are arranged so that their open part is located at the end of the filter facing the mouth of the smoker, the cross-sectional area of the grooves is 0.125-1.00% of the total cross-sectional area of the filter, and the number of grooves is from 3 to 7. In FIG. 1 shows the proposed filter; in fig. 2 shows a filter g attached to a cigarette 5 with the tip shown without a wrapper in FIG. 3 is the same option. FIG. 1 shows the proposed filter having a circumference of 20-27 mm. The filter contains a porous plug 1 made from cellulose acetate or any other material, for example, from the fibers of this or foamy material, which usually wraps around a non-porous material 73 KOU 2. Heat Egp neporist opoptkl stands for (rice | LY ni: 4i; jnp 1) penis surface material that is combined with a filter with aoscopy and temperature, as well as non-porous materials, a material that is not unified by means of an element containing a garlic, a box 3, and a passage of hchihs longitudinally.

Post air through from; " 6, falls into the groove 3 and is directed to kxT) psh: iku. The size and number of holes 6 are determined by the amount of air required for ventilation. FIG. Figure 3 shows another variant of the proposed F1-1ltra5 cr-essing of a tobacco rod or cigarette 4 for wrapping paper 5 which has several openings 6 surrounding the filter and intended to connect the flow with the grooves 3. The filter contains a cellulose acetate plug 1 or another filter material, such as fiber or foam material, and is enclosed in a tubular g (mouthpiece mouthpiece 7, which may have grooves 3 extending along the outer surfaces. If the grooves 3 extend along the entire length, To prevent zibiMa from entering tobacco, or the mouthpiece has a cross-sectional area that is large enough compared to the cross-sectional area of the tobacco so that the grooves 3 open i to the atmosphere.The methods for preparing a tubular mouthpiece are known (for example, extrusion). The proposed filter works as follows: The ventilating air is supplied to the tobacco smoke and surrounds its flow, passing through the filter element in such a way that right after the smoke from the end of the filter facing the mouth is full Stu and instantly disperses and mixes with the surrounding air and venting. Such mixing ensures quick contact of highly diluted smoke with the taste buds of the smoker. In order to achieve instantaneous mixing immediately after the smoke comes out of the filter, it is necessary to provide a cigarette filter with a plurality of channels for ventilation air around the filter element, and the cross-sectional area of such ventilation channels must be determined, the flow rate of the ventilation fan must also be defined. Exhaust and smoke under these smoke exhaust conditions. Instant mixing at the entrance surface of the fsttra can be obtained if the filter for a cigarette ensures the following I / V balance: - 100 where K is 0.035i M the cross-sectional area of an individual channel; AV is the cross-sectional area of the total filter surface and is the percentage of ventilating air in the total flow after the filter, defined by the equation j) oo () V where J, V- is the total flow rate of ventilating airJ cjS is the flow rate of smoke through the filtering element, 1 is the number ducts for ventilation air (must be at least 3, preferably the number of channels is equal to or less than 7). The maintenance of the ventilating air in the general stream (the ventilating air plus dam) should be 60-95%. The ratio of the cross-sectional area of the filter element to the ventilation channels M / Af should be less than 0.01 in order for most smoke to disperse 1 cm (standard filter 20-27 mm in circumference) from the end of the filter when tightened at a speed of 17.5 cm / with. The optimum number of channels is 5 or 4, the venting air is 65-90%, and at least 75% of the dry air is dispersed in t cm from the end of the filter. We offer a cigarette filter to improve the smoke taste when smoking 3S by instantly dispersing tobacco smoke when the filter is srd out of the filter and mixed with ambient air, which ensures fast contact of highly diluted smoke with smoking receptor tastes.
