fire retardant cigarette

Abstract

The invention provides a flame-retardant fireproof cigarette developed aiming at defect of a cigarette end's easy exposure of open fire. The flame-retardant fireproof cigarette comprises: a cut tobacco body; a filter tip core body in a butt joint with the cut tobacco body; a flame-retardant fireproof sleeve covering the whole or a part of the cut tobacco body; and a filter tip paper sleeve covering the filter tip core body, the flame-retardant fireproof sleeve is successively divided into a flame-retardant zone (22) used for preventing combustion and a ventilation zone (23) provided with short-cut seams or micro holes (5a), the ventilation zone (23) of the flame-retardant fireproof cigarette is divided into interconnected multi-sections via multi-strip burning-off lines (6), or protruding ventilation ducts are disposed in the ventilation zone. The burning-out part of the flame-retardant fireproof cigarette during the smoking process can automatically be separated in sections and fall off with hot melt breakage of the burning-off lines, original smoking state and feeling can be kept; and under the effect of suction, air can enter into a cigarette end combustion point along the ventilation duct and the ventilation seams or holes attached to the ventilation duct, providing full combustion of the cigarette end, smooth sucking, and preventing the cigarette end from random turning-off.

Description

technical field [0001] The invention relates to a cigarette, in particular to a flame-retardant and fire-resistant cigarette which can reduce fires caused by burning cigarette ends. Background technique [0002] According to China's "Fire Protection Yearbook" statistics: there are about 10,000 fires (reaching the fire level) caused by smoking in my country every year, causing economic losses in the hundreds of millions. Therefore, it is a better choice to prevent fire accidents from the source to provide smokers with a cigarette that can reduce the ignition rate so as to reduce fires caused by smoking. At present, the flame-retardant and fire-resistant technologies of cigarettes invented abroad are basically adding chemical flame retardants to the cigarette paper or surrounding the chemical flame-retardant strips around the cigarette paper at the end of the cut tobacco body. The cigarette butt will be extinguished by itself due to lack of oxygen. During the smoking process ...

AI Technical Summary

Problems solved by technology

At present, the flame-retardant and fire-resistant technologies of cigarettes invented abroad basically add chemical flame retardants to the cigarette paper or surround the chemical flame-retardant strips around the cigarette paper at the end of the cut tobacco body. The cigarette butt will be extinguished by itself due to lack of oxygen. During the smoking process, the chemical reaction of the chemical flame retardant or the flame retardant strip will change the taste of the cigarette, resulting in dry mouth and pain after smoking. Cigarettes are still exposed to open flames during smoking, and the ignition rate is still quite high
