Definitions

  • 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 conventional filter cigarette comprises a tobacco rod, a filter rod, and a tipping paper connecting and fixing the filter rod to the tobacco rod.
  • two individual wraps 22 a and 22 b are provided to wind two individual filter segments 21 a and 21 b , respectively, a filter rod wrap 23 to wind the two filter segments 21 a and 21 b integrately, and a tipping paper 3 to wind and connect the filter rod 2 to 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.
  • 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. That is, the filtering capacity of a specified filter (measured by the nicotine and tar retention capacity) 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. As the filtering capacity of a filter increases, so does its draw resistance. And 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.
  • 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.

  • Japan PAT617 721 Japan Utility Model Publications Sho48-56185, Korea Utility Model Publications U1985-1337 ( FIG. 2 ), and others, was disclosed a cigarette pipe in which is inserted a device that, utilizing the phenomenon of the collision, condensation, liquidation, and adhesion of the cigarette smoke, induces the cigarette smoke to go through a plurality of holes and collide, as described above, thereby enabling to effectively extract tobacco tar, and such cigarette pipes have been produced on a commercial scale and distributed in the market up to the present.
  • the use of a tar eliminating cigarette pipe as such is a very effective way to overcome the limited filtering capacity of a filter cigarette.
  • the present invention acknowledges that the method of either relying on the filter material or of putting various agents into the filter has an ultimate limit in the filter cigarette and is, therefore, intended to overcome such a limit fundamentally by a filter device that can effectively extract noxious substance.
  • FIGS. 4 (A), (B), (C), and (D) illustrate a transparent filter for the extraction of noxious substance according to the present invention 5 (hereinafter called extraction filter);
  • a conventional filter device which induces the smoke to collide to extract noxious substance, regardless of whether the filter device is placed in a cigarette pipe or inserted inside a filter, there are two separated bodies; the upper body where there are a number of the smoke inflow openings 53 and the lower body where there are a number of the smoke colliding walls 54 , but, in the extraction filter 5 , the smoke inflow openings 53 and the smoke colliding walls 54 are formed in a same body and installed in both the entrance side 53 and 54 and the exit side 53 ′ and 54 ′ of the smoke.
  • the smoke inflow openings 53 of the extraction filter 5 are of a long, narrow quadrangular shape, and the smoke inflow openings 53 are formed inside around the inner circumference of the extraction filter 5 , as shown in FIG. 4 (D).
  • the smoke inflow opening 53 of a quadrangular shape, as shown in FIG. 5 (E), can also induce the smoke inflow to converge and collide, enabling the particles contained in the moisture of the smoke to easily adhere to the wall against which the smoke collides.
  • 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.
  • the smoke inflow openings 53 of a long, narrow quadrangular shape can solve such problem.
  • quadrangular smoke inflow openings 53 enable to position the extraction filter 5 in the end of the filter rod 2 toward the tobacco rod 1 .
  • Agents or tobacco fillers 11 if small, it can pass through
  • such a shape of the smoke inflow opening 53 alleviates draw resistance. If an equal area being installed for the air inflow, 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.
  • 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.
  • 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 number of the filter holders 51 differs, as shown in FIG. 4 (A) and (D), which means that the extraction filter 5 can have various numbers of the filter holders 51 and the smoke inflow openings 53 .
  • the diluted air inflow openings 52 bring about a new working effect interactively in connection with the ventilation holes 31 .
  • the effect of the ventilation holes 31 is obvious. It guarantees the smoker for the more purified smoke and the reduced amount of smoke inhalation.
  • 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.
  • the air flowing in through the ventilation holes mostly fails to mix with the smoke passing through the inside of the filter, flows in its periphery of the filter disc, then is inhaled into the smoker's mouth. 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 flow barriers 55 prevent the exit of the smoke located in the opposite side from being clogged by the extracted noxious substance B. A space is formed where noxious substance stays, stretching after the direction of the smoke inflow, but the flow barriers 55 block the stretching, therefore it possible to design shorter the entire length of the extraction filter S.
  • the flow barriers 55 form a belt following the circumferential direction of the extraction filter 5 , but ribs of a fan in case of composing the extraction filters as shown in FIG. 5 (E).
  • composition shown in FIG. 5 (B) enables to install the smoke inflow openings 53 as shown in FIG. 5 (E) (a frontal perspective view illustrating that the smoke inflow openings 53 are installed toward the center of the circle lengthwise).
  • the extraction filter 5 suitable for the diameter of any and all of the conventional filter cigarettes (slim type included) can be manufactured, and there is no problems in properly adjusting within the filter rod 2 all the specifications for each parts and sections of the extraction filter 5 according to the flavor, quality, and design of the filter cigarette to be targeted and produced.
  • the extraction filter 5 is made transparent, which, in connection with the important compositional factors of the present invention, generates a new visual effect and economic effect as well.
  • a number of the ventilation windows 41 were installed, the area of which is larger than the area of the ventilation holes 31 and a ventilation window is perforated bigger than a ventilation hole.
  • a filter cigarette being composed of the partially transparent filter rod 2 which the transparent filter rod wrap 4 and the partially transparent tipping paper 6 constitute, and combined with a filter cigarette which either contains agents or a device effective for the elimination of noxious substance, will certainly enhance the product value of such a filter cigarette.
  • the present invention being composed of the transparent filter rod wrap 4 , the partially transparent tipping paper 6 , and the partially transparent filter rod 2 , is intended to cope with such prior failures that many filter cigarette developments by the conventional technique had to face in penetrating into the market, and enlarge the acceptability of the consumer for the filter cigarette.
  • the visible is to the invisible what a TV is to a radio, and seeing is believing.
  • FIG. 6 (B) shows a transparent filter rod wrap 4 .
  • the perforation of the ventilation windows 41 is undertaken by laser or other processes, and the ventilation windows 41 are formed before the roller is wound by the wraps.
  • FIG. 6 (C) shows a partially transparent tipping paper 6 .
  • 6 a is an opaque tipping paper, the mouth end segment of the tipping paper 6 , and 6 b is a transparent part.
  • the opaque tipping paper 6 a softens the feeling when the smoker puts it in the mouth and keeps an esthetic sense, and 6 b can be of less transparent color to moderate the rejection of the noxious substance and keep an esthetic sense.
  • the two slant parallel lines show the joints of 6 a and 6 b.
  • the entire tipping paper 6 is made of transparent or significantly transparent material.
  • FIG. 7 is an enlarged fragmentary cross-sectional view of a filter cigarette 10 according to the first actual example of the present invention.
  • FIG. 8 is an enlarged fragmentary cross-sectional view of other actual example of the filter cigarette ( 10 ) according to the first actual example of the present invention.
  • FIG. 8 illustrates a composition of a filter cigarette that omits a transparent tipping paper 6 .
  • FIGS. 8 (A), (B), (C), and (D) all show the application of other actual examples of the extraction filter 5 .
  • the composition of a filter cigarette, as shown in FIGS. 8 (A) and (D), enables to manufacture a cigarette of a soft filter, so unique that the part of depositing the noxious substance can be pressed by a finger.
  • the first individual filter section, 21 a + 22 a can be omitted, and the part of the filter holder 51 of the extraction filter, the mouth end of the filter can be formed flat so that it can be put in the mouthed.
  • FIG. 9 shows a composition of the extraction filter 5 ′ adopting fibrous micro pore.
  • the extraction filter 5 can be manufactured variously according to the features of the targeted filter cigarette and the size of the filter material.
  • FIG. 10 (A) illustrates a view at a viewing angle of the exterior of a transparent extraction filter cigarette 10 in which is inserted an extraction filter 5 according to the first embodiment of the present invention.
  • FIG. 10 (B) illustrates a view at a viewing angle of the exterior of a transparent micro pore extraction filter cigarette 20 in which is inserted a transparent micro pore extraction filter 5 ′ according to the second embodiment of the present invention.
  • FIG. 10 (C) illustrates a view at a viewing angle of the exterior of a transparent filter cigarette 30 containing in the filter rod 2 various agents visible from the outside according to the third embodiment of the present invention.
  • the effect of the filter cigarette of the present invention is clear and diverse.
  • composition in which a number of the smoke inflow openings 53 and a number of the smoke colliding walls 54 of the extraction filter 5 of the present invention constitute a same body and the direction of the extraction filter 5 is reversible, enables not only for the industry to easily adopt the extraction filter 5 of the present invention, but also to overcome the limit of the nicotine filtering capacity and the condensate retention capacity of the conventional fabric filter, thereby protecting the smoker's health.
  • the noxious substance extracted by the extraction filter 5 in the form of nicotine minus the filtering capacity of the volume of the fibrous filter equivalent to the volume that the extraction filter occupies in the filter rod would have been stick to the smoker's mouth, nasal mucosa, and/or lung.
  • the filter cigarette 30 of the present invention being composed of the filter rod 2 a part of which is transparent, will improve the product value of various chamber filter cigarettes containing effective agents for the extraction of noxious substance, and bring about the economic effect of enlarging the acceptability of the consumer.
  • the present invention enables to manufacture the kind of filter cigarettes which can eliminate various kinds of noxious substance.
