As a result of research, it has been found that the problem of outflow of sidestream smoke and clogging of ventilation holes can be solved at once by forming the cylindrical smoking article body using diatomaceous earth as a main raw material.
A patent application has been filed as 327083. This smoking article is typically formed into a bottomed cylindrical shape, and the leading end side of the ignited cigarette is inserted from one end opening thereof, and the outer periphery on the suction side of the cigarette is fitted into the opening. use. Since the leading end side of the cigarette is substantially hermetically housed in the hollow portion inside the smoking article, the sidestream smoke does not flow out. In addition, this smoking article is made mainly of diatomaceous earth, which has a much more dense porous structure than porous glass, and this diatomaceous earth is made denser by devising the moisture content of the raw material, the firing temperature and time, etc. As a result, a more dense porous structure can be achieved, and the outflow of sidestream smoke can be almost completely prevented, and at the same time, the flow of air required for the combustion of tobacco can be minimized. It is desirable that the amount of air circulated be the minimum necessary for burning cigarettes in order to prolong the burning time of cigarettes, suppress the consumption of cigarettes, and enable economical smoking. The smaller the number, the smaller the amount of heat generated per unit time, so that the heat load on the smoking article main body can be reduced and the life of the main body can be extended.

If you also smoke, a large amount of the moisture of the cigarette is absorbed by the smoking device itself, and after a long period of time, it rarely causes cracks, etc.
The taste may not be as good as at the beginning. Therefore, the present invention uses the following air-permeable tubular member in combination.

も効果的に抑制されることが確認された。That is, the present invention is a further improved smoking device using diatomaceous earth as a main raw material, which has a hollow portion capable of hermetically sealing and storing the leading end side of cigarettes, and is composed of diatomaceous earth powder or granules. A smoking article consisting of a cylindrical body whose main material is a cylindrical body, through which a sufficient amount of air necessary for burning cigarettes can be circulated and fine pores remaining to prevent outflow of sidestream smoke remain. , A breathable tubular member that covers the tip end of the cigarette is housed inside the tubular body. Specifically, the tubular member has an alternate multilayer structure of a heat-resistant fiber sheet and a wire mesh sheet, and a carbon fiber sheet is preferable as the heat-resistant fiber sheet, and a stainless steel wire mesh sheet is preferable as the wire mesh sheet. The carbon fiber sheet withstands temperatures of 1000 ° C. to 2000 ° C., and has a deodorizing effect on harmful substances such as nicotine and tar. In addition, the stainless steel wire mesh sheet has an appropriate heat conductivity, and the fire temperature of the cigarette is about 500 to 55 without extinguishing the fire of the cigarette by combination with the carbon fiber sheet.
The temperature can be controlled to 0 ° C. and the thermal decomposition of unpleasant odor components of nicotine and tar can be promoted by the metal catalytic action of stainless steel. Most of the tobacco sidestream smoke is caused by paper wrapping (hemp charcoal).
It has been found that a large amount of purple smoke rises when burning at 0 ° C. or higher, but almost no purple smoke is generated when burning at about 500 to 550 ° C. The harmful components generated from the fire are about 5 at low oxygen levels in the cylinder.
It was found that the thermal decomposition reaction was accelerated at 00 to 550 ° C. and converted to odorless and harmless pyrolysis gas and ash. It was also confirmed that the generation of tars particularly easily generated at around 300 ° C. was effectively suppressed.

て筒状の交互重層構造の喫煙具とする。[0007] Regarding the effect of suppressing the generation of purple smoke, the leading end side of the cigarette was inserted into a cylindrical member of various materials to lower the ignition temperature in various ways. As a result, when the tip of the cigarette is inserted in a contact state or a lightly fitted state into a tubular member in which the carbon fiber sheet and the stainless steel wire mesh sheet are stacked and wound, the ignition temperature is reduced to about 500 to 550 ° C. There was little generation of purple smoke, the fire condition was stable, and there was no residual unpleasant odor of the tubular member. When the fire temperature was made lower with a cylindrical member made of another material, the fire could be extinguished unexpectedly. Conversely, when the fire temperature was raised, the amount of purple smoke generated gradually increased. The alternating multilayer structure of carbon fiber sheet and stainless steel wire mesh sheet lowers the ignition temperature to the optimum temperature for preventing the generation of purple smoke or sidestream smoke, but the same temperature reduction effect can be obtained with other materials or combinations of materials. It cannot be said that it is not. The present invention includes the technical concept of such an unknown material or a combination of materials as long as it has the same temperature reduction effect. The heat-resistant fiber sheet may be a woven fiber sheet such as a plain weave made of carbon fibers, and the wire mesh sheet may have a thickness of about 0.1%.
mmφ metal wire (eg stainless steel wire)
It is possible to weave at the 120th count. The heat-resistant fiber sheet and the wire mesh sheet are wound several times in a stacked state to form a cylindrical alternate multilayer structure. The tubular member having this alternate layered structure can be used as a smoking article as such, and the smoking temperature can be appropriately reduced and controlled by smoking with the leading end side of the cigarette inserted into the tubular member. Generation of sidestream smoke can be prevented. In order to prevent the generation of sidestream smoke, the inner peripheral surface of the cylindrical member is brought into direct contact with the outer peripheral surface of the cigarette, and the fire temperature of the cigarette is reduced to about 500 in a puff-free state.
It is preferable to control the temperature to ５550 ° C. By making the gap on the outer peripheral surface of the cigarette substantially zero, the fire temperature in a puff-free state is stable at about 500 to 550 ° C., and the sidestream smoke generation prevention function is stabilized. The ash mass generated in front of the cylindrical member is stably held inside the cylindrical member, and even a slight outflow of secondary smoke to the distal end side of the cylindrical member can be prevented by the capping action on the fire. In addition, since the ash mass generated in front of the fire has a heat-preserving effect on the fire, it suppresses the generation of tars, which were relatively easy to generate due to the rapid cooling of the gas generated from the non-heat-preserved fire in conventional smoking. At the same time, nicotine and tar generated in a small amount are adsorbed and held on the surrounding heat-resistant fiber sheet and wire mesh sheet, and in this state, thermal decomposition of these nicotine and tar is effective at a fire temperature stably maintained at about 500 to 550 ° C. Harmful gas generated from the fire is converted to odorless and harmless pyrolysis gas and ash. In addition, since the suppression of the fire temperature also has the effect of reducing the combustion speed in addition to the prevention of the generation of sidestream smoke, it is possible to enjoy a lean smoking with a small number of cigarettes while preserving the environment. The carbon fiber sheet is preferably a woven carbon fiber sheet such as a plain weave or a twill weave, and the stainless steel wire mesh sheet is preferably a stainless steel wire having a diameter of about 0.1 mmφ of 100 to 12 mm.
Assume that it is woven at 0th. Then, the carbon fiber sheet and the stainless steel wire mesh sheet are wound several times in a stacked state to obtain a smoking article having a cylindrical alternate multilayer structure.

Activated carbon, sawdust, coffee scum and the like are useful for adjusting the air permeability, and activated carbon is particularly useful for absorbing and removing the odor of nicotine and tar. In the method of manufacturing a smoking article according to the present invention, the mixture is sufficiently kneaded, molded into a product under a predetermined pressure, and then fired or baked at a high temperature (preferably about 900 ° C.). During this baking, the moisture in the raw material diffuses and expands, and the diffusion expansion force promotes the densification of the material mainly composed of diatomaceous earth. The rigidity is significantly improved. Therefore, the smoking article of the present invention can be used for a long period of time without causing any troubles such as cracking or chipping.

対して複数箇所でレーザスポット溶接等で固着する。Although the above configuration is basically sufficient as a smoking device, the ceramic sleeve 6 is removably inserted into the hollow portion 2 as necessary in consideration of the ease of cleaning of tar and tar. In addition, as a measure against water absorption into the main body 1 in addition to easy cleaning of tar and tar, a breathable tubular member 7 as shown in FIG. 4 is removably inserted into the hollow portion 2 as shown in FIG. As shown in FIG. 3, this air-permeable tubular member 7
For example, a plain-woven carbon fiber sheet 7b is superimposed on a stainless steel wire mesh sheet 7a having a fine mesh of about 100 to # 120, and the stainless steel wire mesh sheet 7a and the carbon fiber sheet 7b are wound a plurality of times in the arrow direction in this state. . The carbon fiber is obtained by, for example, using an acrylic resin as a raw material and carbonizing it by steam activation to form a carbon fiber. It is preferable that a large amount of fine porous material is formed in a carbon fiber filament to adsorb an odor. One side of the carbon fiber sheet 7b is slightly folded back to the opposite side (the front side in FIG. 3) beyond the edge of the stainless steel wire mesh sheet 7a, and both ends of the stainless sheet do not overlap the carbon fiber sheet 7b over a predetermined length. Keep it. The folded side of the carbon fiber sheet 7b is the left end of the gas-permeable tubular member 7 in FIG.
Thereby, when the cylindrical member 7 is wound, the tobacco C insertion side at the left end in FIG. 4 is relatively tightly tightened, and the inside diameter at the right end is relatively slightly larger than the inside diameter at the tobacco C insertion side. 7
The tobacco C can be easily inserted into the tobacco. The strong tightening described above also helps to prevent the carbon fiber sheet 7b from shifting.
The carbon fiber sheet 7b is not overlapped on both ends of the stainless steel wire mesh sheet 7a for a predetermined length because the stainless steel wire mesh sheet 7a is exposed on the inner peripheral surface and the outer peripheral surface of the tubular member 7 instead of the carbon fiber sheet 7b. In order to
This makes it easy to clean the inner peripheral surface of the cylindrical member 7 and makes it possible to present a beautiful appearance of a beautiful stainless steel skin on the outer peripheral surface of the cylindrical member 7. In addition, the winding end of the stainless steel wire mesh sheet 7a is fixed to the stainless steel wire mesh sheet 7a overlapping thereunder at a plurality of locations by laser spot welding or the like.

状部材７自体に水分が蓄積されることはない。When a smoking article is used, first, the tip of the cigarette C is ignited, and the lit cigarette C is inserted into the hollow portion 2 of the main body 1 from the tip end side. Fit inside. The tip of the cigarette C from the mouth is the main body 1
Although the main body 1 is porous, the cigarette C
The minimum amount of air required for combustion of the fuel is always supplied. It is desirable that the amount of air is the minimum amount necessary for burning the cigarette C. The smaller the amount of air is, the longer the burning duration of the cigarette C is, and the more economical, and the calorific value per unit time is also reduced. As a result, the heat load on the smoking article main body can be reduced. In addition, the size of the porous micropores is adjusted so that the sidestream smoke of the cigarette C does not flow out.
No sidestream smoke will drift around. In addition, due to the heat insulating property of the diatomaceous earth, a considerable high temperature is maintained inside the main body 1, and harmful substances such as nicotine, tar and carbon monoxide are thermally decomposed by this high temperature. In addition, ash accumulated inside the main body 1 absorbs nicotine, tar, and the like,
When the ceramic sleeve 6 or the air-permeable tubular member 7 is used, nicotine, tar, and the like are also absorbed. Therefore, no matter how many cigarettes C are smoked, the interior of the main body 1 hardly accumulates dirt, and smoking can be continued for a long time without washing. The air-permeable tubular member 7 hardly needs to be cleaned by a self-cleaning function to be described later. However, if necessary, the nicotine, tar, and the like adhered can be easily burned out by taking out occasionally and lightly glowing with a lighter or the like to glow red. be able to. When the air-permeable tubular member 7 is used by being housed in the main body 1, most of the water generated from the cigarette C is absorbed by the cylindrical member 7, so that moisture is absorbed by the main body 1 and cracks or the like occur. Or the decrease in the taste due to the accumulated moisture can be prevented. The moisture absorbed by the tubular member 7 evaporates with the progress of the fire 10 and is sucked out of the smoking device every time the puff is puffed. Therefore, moisture is not accumulated in the tubular member 7 itself.

The breathable tubular member 7 can be used by being housed in the smoking article main body 1 as described above, or can be used alone as shown in FIG. In such a usage, when the number of turns of the tubular member 7 is relatively small, the outer peripheral surface may be slightly heated. It is good to fit. When the permeable tubular member 7 is housed in the diatomaceous earth body 1 and used, its basic functions can be applied to the following description as it is.

It is better to introduce a flame with a lighter or the like from the opposite side of the tubular member 7 and ignite it after inserting. When the cigarette C is ignited and puffed several times, an ash mass 9 is immediately generated as shown in FIG. 6, and the fire type 10 is covered with the ash mass. Thus, the periphery of the igniter 10 is surrounded by the alternating multilayer structure in which the stainless steel wire mesh sheet 7a and the carbon fiber sheet 7b are superposed one after another, and the front of the igniter 10 is closed by the ash mass 9. Since the peripheral gap of the cigarette C is substantially zero, the generated ash mass 9 is stably held by the inner peripheral surface of the tubular member 7 without spontaneous collapse, and the tip side of the tubular member 7 The ash lump 9 does not fall naturally even when turned downward.

生が不可避となる。Since the wrapping paper 11 around the fire 10 is in direct contact with the tubular member 7, its temperature is much higher than that of about 700 to 800 ° C. when nothing is in contact. It is controlled to a low of about 500-550 ° C. And by controlling the temperature of the wrapping paper 11 low as described above,
The generation of purple smoke or sidestream smoke is almost eliminated. Also, even when a small amount of sidestream smoke is generated, the sidestream smoke fine particles are adsorbed by the stainless steel wire mesh sheet 7a or the carbon fiber sheet 7b around the fire 10 or the ash lump 9 in front of the fire 10
, And almost no sidestream smoke comes out of the cylindrical member 7. What is important here is that the outer peripheral surface of the cigarette C is in contact with the inner peripheral surface of the tubular member 7. If cigarette C
If the outer peripheral surface of the cylinder 10 does not contact the inner peripheral surface of the tubular member 7 at all or only partially contacts the
The temperature of the wrapping paper 11 of the cigarette C in the surroundings is set to about 500 to 550.
It is impossible to stably control the temperature to ° C., and the generation of a large amount of sidestream smoke is inevitable.

の不快臭もまったくといっていいほど残らない。The carbon fiber sheet 7b has a thickness of 1000 to 2000
Because of the heat resistance of 0 ° C., it does not burn even if it glows locally at the moment of the puff in the immediate vicinity of the fire source 10. Such a red heat phenomenon is rather convenient for burning off nicotine and tar attached to the carbon fiber sheet 7b. If the stainless steel wire mesh sheet 7a also has a small diameter of the stainless steel wire, it can be easily glowed in the vicinity of the fire 10 and nicotine and tar can be burned off similarly. As described above, since the tubular member 7 has a self-cleaning function of nicotine and tar, there is almost no need to clean the tubular member 7 even when the number of smoking is considerable, and it can be said that there is no unpleasant odor of nicotine or tar. Not much left.

く、残留水分による喫味感の低下はまったくない。Since the cylindrical member 7 is composed of the stainless steel wire mesh sheet 7a and the carbon fiber sheet 7b, the air permeability is very high, and the steam generated from the cigarette C can be completely and instantaneously dissipated to the outside. Therefore, even if smoking is repeated for a long period of time, moisture does not accumulate and remain in the tubular member 7, and there is no reduction in the taste due to the residual moisture.

For example, in the above-described embodiment, the carbon fiber sheet 7b is used as the heat-resistant fiber sheet. The stainless steel wire mesh sheet 7a was used as the wire mesh sheet, but it is a matter of course that a wire mesh sheet made of another heat-resistant fiber sheet such as glass fiber or another metal may be used instead. Further, the cylindrical member 7 may be formed by winding a single layer of a stainless steel wire mesh sheet 7a and a plain-woven carbon fiber sheet 7b, and in this case, for example, the outer peripheral surface side of the cylindrical member 7 Stainless steel wire mesh sheet 7
a is exposed, and the cylindrical member 7 has a two-layer structure in which the carbon fiber sheet 7b is exposed on the inner peripheral surface side.

い喫煙をより手軽に楽しむことが可能となる。As described above, according to the present invention, diatomaceous earth is baked to the bottom in a state where micropores enough to allow the amount of air necessary for burning cigarettes to flow therethrough, and the inside of the cigarette is sucked into the inside thereof. Because it is a smoking device that has a hollow part that can be inserted in a sealed state from the tip side, sidestream smoke does not drift around while putting cigarettes, and because the fire is not exposed, it is due to sleeping cigarettes etc. It is sanitary because there is no danger of fire and no ash is scattered. In addition, diatomaceous earth has excellent heat insulation properties so that it does not feel hot even if you hold the smoking tool directly with your hand, it is lightweight and very convenient to carry, and you carry it in a pocket such as a jacket or shirt during smoking. It is also possible. Furthermore, even if a cigarette is left on fire, the minimum amount of air necessary to continue burning the cigarette is always supplied, so that the cigarette does not disappear naturally and the duration of the fire Is very long, so that a single cigarette can enjoy smoking for as long as needed when needed without wasting cigarettes. In addition, diatomaceous earth is a natural substance, and its disposal on the environment has no impact on the environment. In addition, since the smoking article of the present invention contains a breathable tubular member therein, it is possible to suppress the absorption of moisture into the main body, extend the life of the main body, and reduce the tendency of the taste accompanying the absorption of moisture to decrease. By preventing this, the good taste of the first taste can be maintained for a long time. When the permeable tubular member is used alone as a smoking device, it is lighter and cheaper than when a diatomaceous earth body is used, so that smoking without sidestream smoke can be more easily enjoyed.
