Claims
What is claimed is:
1. A cigarette comprising: a tobacco portion having tobacco inside
and a cigarette paper enrolling said tobacco; a filter portion

2. The cigarette as defined in claim 1, wherein said filter further
comprising a receiving chamber for receiving said
fire-extinguishing unit.
3. The cigarette as defined in claim 1, wherein said
fire-extinguishing unit further comprises a capsule and a closed
room formed inside said capsule for receiving said
fire-extinguishing liquid.
4. The cigarette as defined in claim 3, wherein said capsule
further comprises a spout-out portion formed at an end thereof,
said spout-out portion being more fragile than other portions of
said capsule and facing said tobacco portion, whereby said
fire-extinguishing liquid can easily break through said spout-out

5. The cigarette as defined in claim 1, wherein said cigarette
paper and said wrapping paper are formed in one-piece.
6. The cigarette as defined in claim 1, wherein said
fire-extinguishing liquid is water.
7. The cigarette as defined in claim 1, wherein said
fire-extinguishing liquid is colored.
Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates generally to cigarettes, and
more particularly to a self-extinguishable cigarette.
[0003] 2. Description of the Related Art
[0004] It is generally understood that the common smoker
extinguishes the ash fire of a cigarette directly in the ashtray
while smoking indoors; however, it is difficult to find the ashtray
or ashcan outdoors, such that the smoker may directly desert the
ash fire of the cigarette on the ground, or the smoker may
extinguish the ash fire incompletely and then directly desert it
into the trashcan so as to cause a fire. Some smokers may also
directly throw the ash fire of the cigarette out of the car after
the cigarette is smoked, such that sometimes the news press reports
that the dry objects placed beside the roads are accidentally
burned to cause a catastrophe due to the smokers' carelessness of
randomly deserting the ash fire of the cigarettes.
SUMMARY OF THE INVENTION
[0005] The primary objective of the present invention is to provide
a cigarette, which is self-extinguishable.
[0006] The foregoing objective of the present invention is attained
by the cigarette, which is comprised of a tobacco portion having an
adequate amount of tobacco and a cigarette paper enrolling the
tobacco, a filter portion having an adequate amount of filter and a
wrapping paper enrolling the filter, the filter portion being
connected with the tobacco portion end by end, and a
fire-extinguishing unit embedded into the filter portion and having
a fire-extinguishing liquid, which is ejectable to extinguish the
ash fire of the cigarette while the tobacco portion is squeezed by
an external force.
BRIEF DESCRIPTION OF THE DRAWINGS
[0007] FIG. 1 is a perspective view of a first preferred embodiment
of the present invention;
[0008] FIG. 2 is a cross-sectional view of the first preferred
embodiment of the present invention;
[0009] FIG. 3 is a cross-sectional view of the first preferred
embodiment of the present invention at work; and
[0010] FIG. 4 is a cross-sectional view of a second preferred
embodiment of the present invention.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0011] Referring to FIGS. 1 and 2, a cigarette 100 constructed
according to a first preferred embodiment of the present invention
is comprised of a tobacco portion 10, a filter portion 20, and a
fire-extinguishing unit 30.
[0012] The tobacco portion 10 is formed of an adequate amount of
tobacco 11 and a cigarette paper 12 enrolling the tobacco 11,
thereby being cylindrical.
[0013] The filter portion 20 is formed of an adequate amount of
filter 21, which can be embodied as sponges or other materials
capable of filtering fumes, and a wrapping paper 22 for enrolling
the filter 21, thereby being cylindrical. The enrolled wrapping
paper 22 has an end connected with an end of the enrolled cigarette
paper 12 of the tobacco portion 10. The filter 21 is provided
inside with a receiving chamber 23 axially extending inwards from a
free end thereof.
[0014] The fire-extinguishing unit 30 is embedded into the
receiving chamber 23 of the filter portion 20, having a capsule 31
and a fire-extinguishing liquid 32, for spouting an adequate amount
of the liquid 32 towards the tobacco portion 10 to extinguish the
ash fire of the tobacco portion 10. The capsule 31 is provided with
a closed room for containing the liquid 32, which can be water or
other eatable liquid harmless to human, and a spout-out portion 33
formed at an end thereof and abutting and facing the tobacco
portion 10. The spout-out portion 33 is more fragile than other
parts of the capsule 31 to be easily breakable under a
predetermined pressure. The liquid 32 is ejectable by an external
force to spout from the spout-out portion 33 towards the tobacco
portion 10 to extinguish the ash fire of the tobacco portion
10.
[0015] The cigarette 100 of the first preferred embodiment of the
present invention can be operated according to the following
recitation. When the user ignites the tobacco portion 10 to smoke
it for a length and then intends not to smoke anymore, as shown in
FIG. 3, the user can directly squeeze the filter portion 20 by
fingers to pressurize the fire-extinguishing unit 30. In the
meantime, the liquid 32 inside the capsule 31 is under an
increasing pressure to break through the fragile spout-out portion
33 and to spout on the tobacco portion 10 to directly extinguish
the ash fire. Otherwise, the liquid 32 can be absorbed into the
unfired part of the tobacco 11 or the cigarette paper 12 to
extinguish the ash fire.
[0016] Accordingly, the user can desert the cigarette 100, which
ash fire of the tobacco portion 10 has been extinguished by the
fire-extinguishing liquid 32, into the ashtray or trashcan, thereby
preventing the disaster incurred by incomplete extinguishment of
the ash fire.
[0017] In addition, although the cigarette paper 12 and the
wrapping paper 22 are respectively independent in the first
preferred embodiment, the cigarette paper 12 and the wrapping paper
22 can be alternatively formed in one-piece.
[0018] Further, the fire-extinguishing liquid 32 of the
fire-extinguishing unit 30 can be alternatively colored, e.g. the
liquid 32 can be added with eatable pigment that is harmless to
human, such that not only when the capsule 31 is squeezed to spout
the colored liquid 32, the spouting range of the liquid 32 is
apparently visible, but also when the capsule 31 is accidentally
broken, the liquid 32 can be apparently seen by the user for
attention.
[0019] Referring to FIG. 4, the cigarette 200 constructed according
to a second preferred embodiment of the present invention is
similar to the aforementioned preferred embodiment, having
difference as follows. The fire-extinguishing unit 60 is located
inside the filter portion 50, i.e. the fire-extinguishing unit 60
is put into the filter portion 50 before the filter portion 50 is
formed, and is invisible from the appearance of the cigarette 200
to aesthetically enhance the appearance of the cigarette 200.
