Description

本発明は、非燃焼加熱式タバコの分野に属し、特に密閉加熱式タバコに関する。 The present invention is in the field of non-combustion heated tobacco, and more particularly relates to closed heated tobacco.

従来のタバコは、数百年の歴史を持っており、すでに大多数の喫煙者の生活に根強く浸透している。近年、生活レベルの向上に伴い、喫煙と健康、受動喫煙による被害などの問題がますます注目され、従来のタバコ製品による健康被害が日増しに深刻化している。そして、ＷＨＯたばこ規制枠組み条約の施行に伴い、特に世界各国の公共場所での禁煙範囲が次第に拡大され、タバコ製品の発展環境に重大かつ深刻な変化が起こり、タバコ製品の構造が多様化及び無煙化の方向にますます進んでいる。新型タバコ製品は、従来のタバコ製品の売上の減少に対処するための、各大手タバコ企業の現実的な選択肢となっている。 Conventional cigarettes have been around for hundreds of years and have already permeated the lives of most smokers. In recent years, with the improvement of living standards, more and more attention has been paid to problems such as smoking, health, and the damage caused by passive smoking, and the health damage caused by conventional tobacco products is becoming more serious day by day. And with the implementation of the WHO Framework Convention on Tobacco Control, the scope of smoking cessation in public places around the world has gradually expanded, and the development environment of tobacco products has undergone significant and serious changes. It is progressing more and more in the direction of Novel tobacco products have become a viable option for major tobacco companies to combat declining sales of traditional tobacco products.

現在、ほとんどの非燃焼加熱式タバコは、空気を煙の担体として用い、タバコの非燃焼を確保するために、加熱温度が通常低く３００℃以下であり、従来のタバコに比べて、新型非燃焼加熱式タバコの加香成分が完全に放出されず、煙量が不十分であるため、この種のタバコは従来のタバコ喫煙者に受け入れられにくい。また、空気の流通を確保するために、ほとんどの非燃焼加熱式タバコのタバコ部が開放式構造であり、即ち、タバコ刻み又は再構成タバコシートが直接外部に露出するか、又は所定の気流通路を介して外気と連通し、吸引終了後にカートリッジを取り出す際に、タバコの残渣が落下して喫煙具を汚染しやすいため、この種のタバコは、所定の時間使用した後、喫煙具を洗浄する手間が必要となる。 At present, most non-combustion heated cigarettes use air as the smoke carrier, and the heating temperature is usually lower than 300 ℃ to ensure non-combustion of tobacco, compared with conventional cigarettes, the new type non-combustion Due to the incomplete release of the flavoring components of heated tobacco and the insufficient smoke volume, this type of tobacco is less acceptable to conventional tobacco smokers. In addition, in order to ensure air circulation, the tobacco portion of most non-combustion-heated tobaccos is of an open structure, i.e., the cut tobacco or reconstituted tobacco sheet is directly exposed to the outside, or a predetermined airflow passageway is provided. When the cartridge is taken out after the end of inhalation, the tobacco residue easily falls off and contaminates the smoking implement. It requires time and effort.

［発明の効果］
本発明の有益な効果は、以下の通りである。
１、本発明は、加熱式喫煙具と合わせて使用される密閉加熱式タバコを初めて設計し、密閉加熱式タバコのタバコ部１のタバコ収容室に接触する一端が封止され、生成された新鮮な煙がタバコ内部の雰囲気を置換する役割を果たすため、タバコ内の酸素含有量が加熱に伴って低下し、このとき、加熱温度を上昇させても燃焼することはない。したがって、タバコの加香成分が完全に放出され、煙量が増加するように、加熱温度を上昇させることができる。
２、密閉加熱式タバコのタバコ部１のタバコ収容室に接触する一端が封止されるため、タバコの残渣が落下して喫煙具を汚染することはない。
３、本発明の密閉加熱式タバコは、軸方向の中心空洞２－１及び周方向の側壁貫通孔２－２を有する低吸引抵抗部２を設けることにより、吸引の際に外気が側壁貫通孔２－２から入り、中心空洞内でタバコ部１の加熱による煙と混合して主流煙となって吸引される。そして、吸引の際に外気が側壁貫通孔２－２から入るので、低吸引抵抗部２は、空気流速が高く、圧力が低く、タバコ部１の煙を抽出する役割を果たす。また、外気は煙を降温する役割も果たす。
４、好ましい実施形態において、本発明のタバコは、閉塞プラグ５を用いてタバコ部１を封止するので、タバコの製造工程において、閉塞プラグ５をタバコ部１とともに巻装することができ、工業的生産を容易にする。封止膜等の部材を用いてタバコ部を独立して封止する場合、タバコの製造工程を変更する必要があり、既存の設備の変更が大きく、工業的生産に不利である。
５、好ましい実施形態において、本発明のタバコは、タバコ部１内に複数の軸方向通路を初めて設計し、封止されるタバコ部１内における煙の拡散に有利である。
６、好ましい実施形態において、本発明のタバコは、低吸引抵抗部２には、中心空洞２－１の周方向側壁及び側壁貫通孔２－２を覆うバリア層２－３が設けられ、バリア層は、所定の通気度を有し、吸引時に、外気の流入に影響を与えず、非吸引時に、煙が側壁貫通孔２－２を介して逃げることはないため、煙の流失を効果的に低減することができる。
７、好ましい実施形態において、本発明のタバコは、低吸引抵抗部２に軸方向の煙拡散通路を有する規制案内部材２－４が設けられる。規制案内部材２－４は、所定の通気度を有し、軸方向の煙拡散抵抗が低く、径方向の煙拡散抵抗が高い。吸引時に、外気の流入に影響を与えず、非吸引時に、径方向の煙拡散抵抗が高く、煙が側壁貫通孔２－２を介して逃げることはないため、煙の流失を効果的に低減することができる。タバコの吸引抵抗は、周方向の側壁貫通孔２－２の孔径、数及び規制案内部材２－４の空隙率を変更することにより調整することができる。 [Effect of the invention]
