分を低減させる方法として種々の手段が知られている。(b) Prior Art In general, smoke components produced by smoking cigarettes are composed of various chemical components ranging from low molecules to polymers, and these are broadly classified into gas components and particulate phase components. The particulate phase components account for approximately 8% of the smoke and consist of tar, alkaloids, cochin, etc.), water, etc., and the gas components account for approximately 9% of the smoke.
2%, - carbon oxide, methane, acetaldihyde,
Contains toluene. Among these components, there are components that play an important role in flavor and aroma, and unnecessary gas components that are undesirable from a health standpoint. Various means are known as methods for reducing unnecessary gas components that are undesirable from a health standpoint.

煙を希釈する方法があり、実用化されている。The main methods include loading activated carbon into the filter and adsorbing it, and making small holes in cigarette paper or filter chip vapor and sucking air through the holes when smoking to dilute the smoke. It has been put into practical use.

昭４３−７８４０号に示されている。In addition, cigarette smoke filters have been proposed, which are characterized by containing finely divided metal oxides as a main component and adsorbent particles impregnated with these particles, such as JP-A-60-70065 and JP-B-Sho.43- No. 7840.

よって除去し、喫味を改善させるものである。Cigarette filters whose main components are these metal oxides are
This is a proposal for a method for removing harmful components contained in cigarette smoke, and its principle is to remove these components through adsorption or oxidation to improve smoking taste.
又、これら金属酸化物の混合体は、遠赤外線を放射する
が、極めて微弱なものであり、煙の中に含まれる水質の
改善効果は何ら認め、られない。Further, although the mixture of these metal oxides emits far-infrared rays, it is extremely weak, and no improvement effect on the quality of water contained in smoke can be observed.

。(c) Problems to be Solved by the Invention Conventional activated carbon adsorption methods generally have the disadvantage of adsorbing smoke components useful for flavoring at the same time as unnecessary gas components, and the open-hole air dilution method The drawback is that the flavor components are also diluted at the same time as the unnecessary gases. Furthermore, the main purpose of adding metal oxides in the past is merely to remove harmful components through adsorption or oxidation, as described above.
この発明は、従来法の欠点を補うとともに、従来とは全
（異なる観点から、特に香喫味の改善をしようとするも
のである。This invention aims to compensate for the shortcomings of the conventional method and to improve the aroma and taste from a different perspective than the conventional method.

うとするものである。(d) Means and action for solving the problems According to the present invention, the above-mentioned problems can be solved by adding a sufficient amount of smoke to the filter unit, which is either integrated with the cigarette or separate from the cigarette, to improve the aroma and taste. This problem is attempted to be solved by a cigarette filter characterized by adding highly efficient far-infrared emitting inorganic fine particles.
この発明のタバコ用フィルターの構造は、特に限定され
ない。すなわち、現在の市販品の多くにみられるフィル

部であってもよい。The structure of the cigarette filter of this invention is not particularly limited. That is, it may be a filter part of a rolled tobacco product (for example, Mild Seven, Cabin, etc.) in which the filter part and tobacco part are integrally formed, which is found in many current commercial products.
しかしながら、これらのタバコ製品とは別に、基本的に

宜利用される。However, apart from these tobacco products, it is preferred that there is a separate filter, which essentially consists of a tobacco product insert, a filler load and a mouthpiece. This is because such a separate filter can be used repeatedly and is economically preferable. Various types of separate filter structures are known, and any structure can be used as appropriate as long as it can be filled with the inorganic fine particles of the present invention.

用いることができる。The highly efficient inorganic particles that emit far infrared rays, which is a feature of this invention, mean fine inorganic particles that can strongly emit far infrared rays in order to efficiently achieve the effects of this invention. Far-infrared emitting inorganic particles are generally known and available,
Highly efficient products can be selected from commercially available products. The material for such inorganic fine particles generally consists of at least one type of i-free oxide consisting of zirconium oxide, cobalt oxide, iron oxide, manganese oxide, copper oxide, titanium oxide, silicon oxide, chromium oxide, and aluminum oxide. Ru. These inorganic oxides are also used as sintered bodies with betalite, cordierite compositions, mullite, clay, etc. In some cases, betalite, cordierite mullite, and β-spodumene can be used as the far-infrared ray-emitting inorganic fine particles.

However, the amount needs to be sufficient to improve the aroma and taste of tobacco. The filter of this invention includes:
In addition to the above inorganic fine particles, ordinary activated carbon, silica gel,
A filler made of pumice or the like may also be used. An example of the amount of inorganic fine particles to be used when a filler is used is 1 to 35% by weight, preferably 2 to 15% by weight, based on the filler. Note that the filler is preferably in the form of particles of 50 to 80 mesh. Furthermore, fillers and inorganic fine particles are
It is desirable that the particles be dispersed as uniformly as possible. A suitable adhesive (for example, methylcarboxycellulose, various adhesive polymers) may be used to maintain this state and optionally adhere to the filter material.

のと思われる。Specifically, the improvement in smoking taste achieved through the use of the far-infrared emitting inorganic fine particles of the present invention is typical in that the taste is milder and less irritating. Although its mechanism of action has not yet been clarified, it is thought to be brought about by improving the water quality contained in cigarette smoke, and is thought to have a completely different effect from that of the various fillers in conventional cigarette filters. .
