本考案は喫煙具に関するものであり、更に詳し
くは喫煙の際に発生する紫煙を抑制する喫煙用補
助具に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a smoking device, and more specifically to a smoking aid that suppresses purple smoke generated during smoking.
タバコの煙には喫煙者が直接吸込む所謂主流煙
と置きタバコより立ち昇る所謂副流煙(紫煙)が
あり、副流煙は主流煙よりも刺激性と不快感が強
く且つ人体に有害であることが知られている。
Cigarette smoke is divided into so-called mainstream smoke, which is directly inhaled by smokers, and so-called sidestream smoke (purple smoke), which rises from a placed cigarette.Sidestream smoke is more irritating and unpleasant than mainstream smoke, and is harmful to the human body. It is known.
主流煙に比べて副流煙はその生成温度が200〜
300℃と低く、また生成アミン類のために強いア
ルカリ性を示すことも特徴である。 Compared to mainstream smoke, sidestream smoke has a generation temperature of 200~200°C.
It is characterized by its low temperature of 300℃ and strong alkalinity due to the amines produced.
この様な副流煙を簡単に抑制する手段として微
粉状炭素を漉き込んだ紙でタバコを巻き炭素の燃
焼熱によつて副流煙の発生を抑制する方法がある
が、この方法はタバコが太くなるので包装容積が
大きくなるばかりでなく着火した炭素粒が落るた
め火災の危険があつた。 One way to easily suppress such sidestream smoke is to wrap a cigarette in paper containing finely divided carbon and use the combustion heat of the carbon to suppress the generation of sidestream smoke. Not only did the thicker packaging result in a larger packaging volume, but the ignited carbon particles could fall, creating a risk of fire.
また、タバコの燃焼部分に不燃性の筒をかぶせ
る方法が考案されているがこの方法は筒を長くす
るとタバコが立ち消えする欠点があつた。 Additionally, a method has been devised in which a non-flammable tube is placed over the burning part of the cigarette, but this method has the disadvantage that the longer the tube is, the more the cigarette will disappear.
縦長の孔にタバコを挿入して自然に消火する灰
皿があり、この場合も短時間ならば副流煙の発生
を抑制することができるがこの灰皿は非通気性材
料によつて形成されており、空気の供給を抑制し
て消火するものであるから喫煙を継続するために
は絶えず火が消えない様に注意しなければならな
い欠点があつた。 There are ashtrays that extinguish the fire naturally by inserting a cigarette into a vertical hole, and in this case too, the generation of sidestream smoke can be suppressed for a short period of time, but these ashtrays are made of non-breathable material. Since the fire is extinguished by suppressing the air supply, it has the disadvantage that in order to continue smoking, care must be taken to ensure that the fire does not go out.
本考案は前述した様な従来の手段における様々

The present invention eliminates the various drawbacks of the conventional means as described above, and provides a smoking aid that safely and easily suppresses unpleasant components in sidestream smoke, and that can easily extinguish cigarettes when necessary. The purpose is to provide
前述した問題点を解決するために本考案の喫煙

In order to solve the above-mentioned problems, the smoking aid of the present invention has a first layer 5 that is heat-resistant, breathable, and has low thermal conductivity, and a second layer 6 that is impermeable and has high thermal conductivity. A cigarette holding member 2 is formed by laminating layers such that one of the layers is on top, and a cigarette holding member 2 is provided with a cigarette inserting member that penetrates through the boundary surface 7 of the first layer 5 and the second layer 6 and opens on at least one side. It has a structure in which holes 3 are provided.
第1の層5はタバコの火によつて燃えたり変形

ルミナ繊維、石英ガラス繊維等の積層物より選択
される。 The first layer 5 has a heat resistance of 800 to 1200 degrees Celsius to the extent that it will not be burned or deformed by cigarette fire, has breathability that can supply the air necessary for the cigarette to continue burning, and has sufficient heat resistance to burn the cigarette. It is made of a material with a low thermal conductivity that can sufficiently store heat without dissipating it, and such a material has a thermal conductivity of 0.5 min -1 cm -2 or more at a pressure difference of 40 mm water column. Selected from laminates of asbestos, alumina fiber, quartz glass fiber, etc. below 0.1Kcal・m -1・hr -1・deg -1 .
第2の層6は燃焼するタバコに供給される空気

等より選択される。 The second layer 6 is made of a material that is sufficiently impermeable to block the air supplied to the burning tobacco and has a high thermal conductivity to dissipate the heat of combustion of the tobacco and reduce the temperature of the burning part. Such materials are selected from metals, high temperature plastics, ceramics, etc.
孔3はタバコを挿入し得る程度の大きさであつ
てタバコの表面に沿つて空気が流れることを防ぐ
ためにはタバコと孔3の内壁間には隙間がないこ
とが好ましい。 The hole 3 is large enough to allow insertion of a cigarette, and preferably there is no gap between the cigarette and the inner wall of the hole 3 in order to prevent air from flowing along the surface of the cigarette.
本考案の喫煙補助具において置きタバコの必要
が生じたとき火の付いたタバコをタバコ保持部材
2の孔3に挿入して、その燃焼部分を通気性を有

ことなく燃焼を継続する。
When it is necessary to place a cigarette in the smoking aid of the present invention, a lit cigarette is inserted into the hole 3 of the cigarette holding member 2, and the burning part is placed inside the first layer 5 having air permeability. When this is done, air is supplied through the layer 5, so that the cigarette continues to burn without being extinguished.
しかも第1の層5は熱伝導率が低いので燃焼熱
は放散されることなく蓄積されて燃焼部分の温度
を上昇せしめるから、低温燃焼のとき発生する不
快な刺激臭を有する副流煙(紫煙)の発生が抑制
される。 Moreover, since the first layer 5 has a low thermal conductivity, the combustion heat is accumulated without being dissipated and increases the temperature of the combustion part, which causes sidestream smoke (purple smoke) with an unpleasant irritating odor that is generated during low-temperature combustion. ) occurrence is suppressed.
更に、燃焼部分から層5の内部へ拡散する煙は
蓄積された燃焼熱で高温になつた層5の部分を通
過することになるので熱分解を受ける結果タバコ
保持部材2の外部へ出る煙は一層減少する。 Furthermore, the smoke that diffuses into the layer 5 from the combustion part passes through the layer 5 that has become hot due to the accumulated combustion heat, so that the smoke that escapes to the outside of the cigarette holding member 2 as a result of being thermally decomposed is Further decrease.
この様にして第1の層5の内部で燃焼を継続す

るから空気の供給を遮断し、しかも高い熱伝導率
によつて燃焼熱を放散して温度を下げるからタバ
コは燃焼を停止して消火される。 In this way, the cigarette that continues to burn inside the first layer 5 has holes 3 that penetrate through the interface 7 between the first layer 5 and the second layer 6 and are provided as continuous holes. , the combustion part can be easily positioned inside the second layer 6 without extracting it from the hole 3, but at this time, since the second layer 6 is non-breathable, the supply of air is cut off, Moreover, its high thermal conductivity dissipates combustion heat and lowers the temperature, so the cigarette stops burning and is extinguished.
また、タバコが第2の層6に設けられた開口部
から挿入されて先端の燃焼部分が第1の層5の内
部にあるときは、該燃焼部分は燃焼の進行につれ
て自然に第2の層6に移行するからタバコは自動
的に消火する。 Further, when a cigarette is inserted through the opening provided in the second layer 6 and the burning part at the tip is inside the first layer 5, the burning part will naturally move into the second layer as combustion progresses. 6, the cigarette will be extinguished automatically.

激臭は激減していた。 When a lit cigarette 4 is inserted into this smoking aid and the burning part 9 at the tip is positioned inside the first layer 5, the cigarette continues to burn without extinguishing, and at this time, no purple smoke is generated. The unpleasant and unpleasant irritating odor has been drastically reduced.
次いでタバコ4は挿入の程度を浅くして燃焼部
分を第2の層6に移行せしめると間もなく簡単に
消える。 The cigarette 4 is then inserted shallowly to transfer the burning portion to the second layer 6, whereupon it easily extinguishes.
また、第1の層5の内部で燃焼を継続していた
タバコ4は放置しておくと燃焼にともなつてやが
て燃焼部分9が第2の層6に移行して間もなく自
然に消えた。 Furthermore, if the cigarette 4 that had continued to burn inside the first layer 5 was left unattended, as it burned, the burnt portion 9 would eventually move to the second layer 6 and soon disappear by itself.
