  • the present invention relates to a filter cigarette. Particularly the present invention relates to improving a filter device for extracting the noxious substance of cigarette smoke, and a filter rod wrap and a tipping paper to enhance the product value of the cigarette.

  • a tobacco rod 1 which comprises a tobacco filler 11 and a tobacco wrap 12 winding the tobacco filler 11, thereby a filter cigarette is comprised.
  • various methods have been developed toward the improvement of not only the quality of the tobacco filler but also the function of the filter in order to minimize the bad effect of cigarette smoking on a human body.
  • the filter wraps 22a, 22b and 23 winding the filter rod 2 being referred they are made of porous paper or non-woven fabric of outstanding ventilation, which, as a medium to induce air to flow in from the outside of the filter in order to reduce the constituents of the inhaled smoke, serves the purpose of smoothing the ventilation between the ventilation holes 31 perforated through laser or other processes on the tipping paper 3 and the interior of the filter.
  • cellulose acetate solutions are most commonly used in the current market, and a method of enlarging the surface area of a filter in order to increase the condensate retention capacity of the filter or of using the cellulose mixed with materials other than acetate, micro-fibril, paper, and non-woven fabric has been developed and adopted for the filter material 21.
  • Similar fibrous filters made on the cellulose basis have the merit of efficient production process, visual homogeneity of a cross-section of the filter, filterability of nitrosamine and phenol, etc., but they also have a major demerit to be improved: the filtering capacity of a filter is limited and defined by the draw resistance and the physical specifications for the composition of the filter.
  • the filtering capacity of a specified filter is defined by the draw resistance of the filter and the density of the fabric used, and there is no way of maintaining the requirements for a filter's length, diameter, draw resistance, the density of the fabric used, and so on, and, at the same time, increasing the filtering capacity of the filter.
  • the filtering capacity of a filter increases, so does its draw resistance.
  • the size of a filter can not be indefinitely enlarged in order to increase the filtering capacity and the condensate retention capacity of the filter. As described above, there is a limit in the condensate retention capacity and the particle filtering capacity of the filter material itself.

  • the filter material alone can not eliminate such a limit in the condensate retention capacity and the filtering capacity of a filter, methods of putting various agents into the filter rod 2 have been devised in order to complement such a limit; a process of putting agents in a chamber formed either between the filter segment 21a and 21b or in other position, and a process of putting and dispersing agents inside the filter segment 21b.
  • the agents so devised that can be used for the filter material 21 cover a variety of minerals, plants, and chemical materials such as carbon powder, silicon dioxide, zeolite, various metals, metallic oxide, green tea powder, aromatics, salt roasted in bamboo, pine resin, artemisia, various medical herbs, and so on, most of which, except a few like activated carbon powder, are not actually used in the market because of the increase in manufacturing expense, difficulties in improving the product value accordingly to the increase of the manufacturing cost, the uncertainty of the effectiveness, and so on. Even the added carbon powder is just supplementary, not enough to bring about a significant effect for the elimination of noxious substance. Thus, there exist no filter cigarettes in the market safe from the noxious substance from cigarette smoking because of the limit in the filtering capacity of the filter. This is obvious up-to the present. [Description of the Drawings]

  • the monolithic composition in which the smoke inflow openings 53 and the smoke colliding walls 54 constitute the same body as such is a very important factor for a high efficiency of the filter producing process.
  • all conventional filter devices have a fixed direction of the smoke inflow for the compositional reason, therefore, if the insertion of the filter device is reversed, it can no longer work, whereas the extraction filter 5 can extract the noxious substance of the smoke, regardless of whether the smoke flows in through the front end or the rear end of the extraction filter 5.

  • such quadrangular shape of the smoke inflow opening 53 serves the purpose of the various application of the extraction filter 5 inside the filter rod 2.
  • most of the filter cigarettes have a dual filter composition, and, in many cases, activated carbon or other agents are added and dispersed, in which case the powders of the agents are likely to clog the smoke inflow holes, causing difficulties in the composition of a cigarette with a filter device inserted.

  • Agents or tobacco fillers 11 if small, it can pass through
  • the draw resistance of a filter with a number of the smoke inflow openings 53 of a long quadrangular shape is less than that of a filter with a plurality of the small holes. Further, as shown in Fig. 4(D), the smoke inflow openings 53 are installed within the ventilation area of the diluted air inflow openings 52 between two neighboring filter holders 51.
  • the position of the smoke inflow openings 53 as such enables the air flowing in through the diluted air inflow openings 52 to immediately collide with the smoke inside.
  • the smoke can pass and collide at the two corners of the smoke inflow openings 53 faster than through the round holes, thereby enhancing the effect of extracting noxious substance.
  • another smoke colliding wall 54' is formed, as shown in the circle of Fig. 4(B), so that the smoke may first collide against the smoke colliding wall 54, and another smoke colliding wall 54'one more time.
  • the filter holders 51 do not surround the whole filter segments 21a and 21b like a tube, but are separated. In most cases, the filter holder blocks the periphery of the filter disc, causing a problem of being unable to utilize the periphery of the filter disc.
  • the separated filter holders 51 can solve such a problem, and the narrower the area of the filter holders 51 and the less the number of the filter holders 51 is, the better.

  • the conventional filter device dominantly relying on the ventilation holes has the disadvantage not only of "air taste” but also of the inability to utilize the filtering capacity of the periphery of the filter disc.
  • Recent techniques were devised to enhance the effect of ventilation holes and solve the disadvantage mentioned in the above, but to fail to meet the expectations: Korea Patent Office Application No. 10- 2001-7005178 was intended to solve the disproportion of the air inflow ratio between the ventilation holes and the inside filter, but was unable to solve the disadvantage of the ventilation holes mentioned in the above, and Korea Patent Office Application No. 10-2002-7004931 still left the problem of "air taste” unsolved.

Only the amount of the smoke can be reduced but most of the smoke is mixed with air inside the smoker's mouth. As a result, what the consumer call "air taste" causes a loss of the cigarette taste.
  • the smoke flowing in the periphery of the filter disc being blocked by the air flowing in through the ventilation holes, brings about a phenomenon of converging toward the center part of the filter, and most of the air inflowing from the outside flow in the periphery of the filter disc, so the filtering capacity of the periphery of the filter disc can not be fully utilized.
