Abstract
A flame-retardant and fireproof cigarette which aims to contain the combustion process to the cigarette. The flame-retardant and fireproof cigarette has a filter that is aligned with a tobacco body. A flame-retardant and fireproof covering is positioned over at least a portion of the tobacco body and isolates the open fire associated with the consumption of the tobacco during the course of smoking or burning the cigarettes. Such a cigarette reduces the risk of undesired, inadvertent, and latent ignition of adjacent materials.
Claims20
A flame-retardant and fireproof cigarette, comprising:
- an internal core having a filter core and a tobacco body which are aligned in an end to end orientation;
- an external casing wrapping the internal core, which includes a filter paper casing, a flame-retardant and fireproof covering and a cigarette paper casing;
- wherein
- the filter paper casing wraps the filter core, and the flame-retardant and fireproof covering and the cigarette paper casing individually wrap the tobacco body;
- the flame-retardant and fireproof covering is arranged between the filter paper casing and the cigarette paper casing, so as to prevent the tobacco body in the state of burning from being exposed to the outside when the tobacco body burns and reduces its length to be inside of flame-retardant and fireproof covering;
- and
- the flame-retardant and fireproof covering is made of incombustible materials and is equipped with a ventilated area for stimulating static burning.
A flame-retardant and fireproof cigarette, comprising:
- an internal core having a filter core and a tobacco body which are end to end joined to each other;
- an external casing wrapping the internal core and which includes a filter paper casing and a flame-retardant and fireproof covering,
- wherein the filter paper casing wraps the filter core, and the flame-retardant and fire proof covering individually wraps the tobacco body;
- the tobacco body is fully wrapped by the flame-retardant and fireproof covering, so as to prevent the tobacco body in the state of burning from being exposed to the outside during the course of smoking;
- and
- the flame-retardant and fireproof covering is made of incombustible materials and is equipped with a ventilated area for stimulating static burning.
A flame-retardant and fireproof cigarette, comprising:
- an internal core formed by a filter core and a tobacco body which are end to end joined to each other;
- an external casing wrapping the internal core, the external casing including a filter paper casing, multiple sections of flame-retardant and fireproof covering that are mutually separated, and a number of cigarette paper casings that are located between adjacent sections of the flame-retardant and fireproof covering;
- wherein
- the filter paper casing wraps the filter core, and the multiple sections of flame-retardant and fire proof covering and the cigarette paper casings cooperate to individually wrap the tobacco body;
- the multiple sections of flame-retardant and fireproof covering are made of incombustible materials, and an end section of the multiple sections of flame-retardant and fireproof covering adjacent to the filter core is equipped with a ventilated area for stimulating static burning;
- and
- the sections of flame-retardant and fireproof covering are bonded together by means of the cigarette paper casings so that the sections of flame-retardant and fireproof covering fall off one by one with in-order burnout of the cigarette paper casings.
