Definitions

  • the present invention relates to a cigarette filter for allowing cigarette smoke to uniformly diffuse to the entire sectional area of the filter during inhalation so as to more easily remove harmful materials, such as nicotine or tar, included in cigarette smoke.
  • cigarettes habitually used as favorite consumables are cylindrical rolls of finely cut dried tobacco which generate a variety of toxic materials, such as nicotine and tar, harmful to the human body, during inhalation.
  • toxic materials such as nicotine and tar
  • harmful materials included in cigarette smoke are inhaled into the human body and thus greatly affect the body.
  • toxins are repeatedly sucked into the lungs and the bronchi, they are deposited in said lungs and may cause a variety of serious diseases, such as phthisis and lung cancer.
  • the toxins are known to be the cause of many diseases because the toxins absorbed to the mouth, tne nose, the bronchi and the gastric mucosa, accelerate a secretion of adrenaline, thus contracting blood vessels. Accordingly, a broad antismoking campaign is now underway. However, since tobacco smokers are addicted to nicotine, it is very difficult for smokers to quit smoking cigarettes.
  • the filters of cigarettes designed to filter harmful materials, such as nicotine and tar, are provided at one end of the cigarette.
  • Such filters are typically classified into several types as follows: That is, the conventional filters of the cigarettes are classified according to their structure into a single filter consisting of one integrated filter, a double filter formed by a linear arrangement of two filter segments, and a multiplex filter formed by the linear arrangement of a plurality of different kinds of filter segments.
  • the filters are also classified according to the material of the filters into a fiber filter, a chemical granule-laden filter, and a carbon granule-laden filter.
  • fiber filters allow hazardous materials included in the cigarette smoke to simply pass through their fibrous matrix, and thus a large effect cannot be expected.
  • fiber filters particularly those laden with carbon or chemical granules for removing nicotine and tar, have been most preferably and widely used as filters for cigarettes.
  • the fibrous material of the filter is oriented along the axis of the filter so as to be parallel to the flow current of the sucked smoke while smoking the cigarette.
  • the fibrous material of the fiber filter is parallel to the flow current of the sucked smoke while smoking the cigarette, the smoke is hydrodynamically concentrated to the portion around the central axis of the filter. Therefore, the suction force of the smoker's lungs while smoking a cigarette most strongly acts along the central axis of the cylindrical fiber filter, thus forcing the toxic substances, such as nicotine and tar, to be concentrated and deposited in the portion around said central axis of the filter.
  • the nicotine and tar are concentrated and deposited in the portion around the central axis of the filter while smoking a cigarette as described above, the filter is reduced in its filtering function and cannot accomplish its designed filtering function.
  • silica gel has a large perforation diameter, nicotine or tar is effectively adsorbed but harmful materials in gas phases are not collected within the micro perforations and thus to pass through a filter, whereby the adsorption rate for harmful gaseous material is less than desired. Also, since silica gel itself is hydrophilic and thus adsorbs moisture in the tobacco smoke during inhalation, the smoker feels a sensation of dryness. Hence, these methods have not been used in recent years. Alternatively, there have recently been developed cigarette filters which are added with materials providing a deodorization function and an aromatic property. For instance, Korean Patent Laid-Open No.
  • Korean Patent Laid-Open No. 95- 24708 refers to a cigarette filter containing green tea, wherein various green-tea powders are added to a tobacco filter to remove odors in the mouth.
  • 97-11847 refers to a bamboo-salt cigarette filter, in which bamboo-salt particles (0.1-0.5 mm) 0.1-0.5 g are used to form a layer of bamboo-salt particles, whereby harmful materials in the tobacco smoke are removed and taste of tobacco becomes mild.
  • a cigarette filter comprising two filters, two filtering nets and a disc-shaped diffusing body having pluralities of perforations, said filtering-nets being formed by immersing fibers such as non-woven fabric or cotton in mugwort and pine resin and thus allowing said components to impregnate into the fibers, and then drying, wherein, while smoking the cigarette, cigarette smoke passes through a front filtering-net to primarily filter harmful materials in the smoke, and then through perforations in the diffusing body to uniformly diffuse the smoke to the entire sectional area of the filter while passing through a back pine resin-impregnated filtering-net to secondarily filter the remaining nicotine and tar after primary filtering, thus easily removing hazardous materials, such as nicotine and tar.
  • a cigarette filter for easily removing hazardous materials like nicotine and tar comprising finely cut tobacco at one end of the cigarette, and a filtration portion for filtering harmful materials in cigarette smoke at the other end of the cigarette, wherein the filtration portion comprises two filters made of a fibrous or cotton-fabrics at the outmost opposite sites, two filtering-nets made of non-woven fabric or cotton at inner sides of the filters, and a diffusing body with a plurality of perforations between said filtering-nets.

  • Fig. 2 is a cross sectional view showing a cigarette filter of the present invention. * Description of the Reference Numerals in the Drawings *
  • the present invention provides a cigarette filter comprising an arrangement of filtering-nets and a disc-shaped diffusing body, said filtering-nets being formed by impregnating non-woven fabrics with mugwort and pine resin in liquid states prior to drying and said diffusing body having a plurality of perforations, in which cigarette smoke passes through the filtering-nets during inhalation to remove harmful materials such as nicotine and tar, and then through the diffusing body to uniformly diffuse to the entire sectional area of the filter, thus effectively being removed of hazardous materials and protecting the bronchi by virtue of the aromatic properties of the mugwort and the pine resin incorporated in the filter.
  • FIG. 1 A perspective view and a sectional view of a cigarette filter of the present invention are shown in Figs. 1 and 2.
  • a cigarette 1 comprises finely cut tobacco 2 at one end of the cigarette, and a filtration portion 3 provided with a fibrous filter 4 for filtering harmful materials, such as nicotine and tar, from cigarette smoke, at the other end of the cigarette, wherein the fibrous or cotton-fabrics filter 4 is bisected to form two filters 4 and 5, and a mugwort-impregnated filtering-net 7 and a pine resin-impregnated filtering-net 8 are set at a position between the bisected filters 4 and 5, and also a disc-shaped diffusing body 6 in which a plurality of perforations are formed is located between said filtering-nets 7 and 8, thus constituting the filtration portion 3.
  • a fibrous filter 4 for filtering harmful materials, such as nicotine and tar
  • a diffusing body 6 made of synthetic resin material also cut as described above has a total number of perforations 9 of between about 5 and 30, thus creating a desired smoke diffusing effect.
  • the mugwort and the pine resin included in the filtering-nets 7 and 8 are materials harmless to the human body, and have not only a medicinal function of protecting the bronchi and the lungs from the smoke, but also efficiently purify said organs, thus preventing various diseases including bronchitis during inhalation.
  • the smoker feels normal during inhalation, which results from the aromatic properties of the mugwort and the pine resin incorporated in the filter.
  • the diffusing body 6 is set at a position between the mugwort- incorporated filtering-net 7 and the pine resin-incorporated filtering-net 8, which are located between bisected fiber or cotton filters 4 and 5, thus constituting the filtration portion 3.
  • the smoke While passing through the fiber or cotton filter 4, hazardous substances such as nicotine and tar are adsorbed to the fibrous matrix of the filter 4. Thereafter, the remaining hazardous substances in the smoke not adsorbed to the filter are primarily filtered through the mugwort-incorporated filtering-net 7. Next, the smoke is hydrodynamically diffused to the entire sectional area of the filter via a plural number of perforations in the diffusing body 6. The reason why the smoke is hydrodynamically diffused is that the diameter of the perforations is gradually enlarged in a direction from the smoke inlet to the smoke outlet.
  • the smoke is secondarily filtered through the pine resin-incorporated filtering-net 8 set at the back of the diffusing body 6, thus passing through the back filter 5 while uniformly being diffused to the entire sectional area of the back filter 5, whereby the still- remaining nicotine and tar can be adsorbed to the fiber or cotton filter.
  • the smoke primarily passes through the filtering-nets 7 and 8.
  • the mugwort and the pine resin impregnated into the filtering-nets 7 and 8 may be sucked into the human body, along with the cigarette smoke, thus protecting bronchi or lungs from the smoke and effectively removing the offensive odor of the cigarette smoke, by virtue of their aromatic properties.
  • the mugwort and the pine resin may be added in the form of fine powders or granules to the filtering-nets 7 and 8, without affecting the functioning of this invention.
  • the present invention provides a cigarette filter for easily removing harmful materials.
  • harmful materials such nicotine and tar from cigarette smoke
  • harmful or toxic materials such as nicotine and tar
  • the remaining harmful ingredients can be effectively removed through the pine resin- impregnated filtering-net and then the back filter.
  • the filter of this invention has superior filtering efficiency compared to conventional ones. Also, the filter which incorporates mugwort and pine resin therein thus is helpful in preserving the health of the smoker, as well as allowing the smoker to feel normal during inhalation, which results from the aromatic properties of the mugwort and the pine resin impregnated into filtering-nets present within the filter.
