TRANSPARENT EXTRACTION FILTER CIGARETTE
DESCRIPTION
[Technical Field]
The present invention relates to a filter cigarette. Particularly the
present invention relates to improving a filter device for extracting the
noxious substance of cigarette smoke, and a filter rod wrap and a tipping
paper to enhance the product value of the cigarette.
[i~ackground Art]
As shown in Fig. 1, a conventional filter cigarette comprises a tobacco
rod, a filter rod, and a tipping paper connecting and fixing the filter rod to
the tobacco rod.
The composition being viewed more closely, in a dual filter composition
as shown in Fig. 1, two individual wraps 22a and 22b are provided to
wind two individual filter segments 21a and 21b, respectively, a filter rod
wrap 23 to wind the two filter segments 21a and 21b integrately, and a
tipping paper 3 to wind and connect the filter rod 2 to a tobacco rod Z
which comprises a tobacco filler 11 and a tobacco wrap 12 winding the
tobacco filler 11, thereby a filter cigarette is comprised.
Nowadays, as the bad effect of cigarette smoking is widely known to the
consumer, various methods have been developed toward the
improvement of not only the quality of the tobacco filler but also the
function of the filter in order to minimize the bad effect of cigarette
smoking on a human body.
The filter wraps 22a, 22b and 23 winding the filter rod 2 being referred,
they are made of porous paper or non-woven fabric of outstanding
ventilation, which, as a medium to induce air to flow in from the outside
of the filter in order to reduce the constituents of the inhaled smoke,
serves the purpose of smoothing the ventilation between the ventilation
holes 31 perforated through laser or other processes on the tipping
paper 3 and the interior of the filter.
A number of the methods for improving the ventilation between the
ventilation holes 31 and the interior of the filter were introduced; in
Korea Patent Office Application No. 10-2001-70051°l8 was disclosed
a
method which used an embossed paper for the filter rod wrap 23, and in
CA 02525128 2005-08-02
WO 2004/068975 PCT/KR2004/000206
Korea Patent Office Application No. 10-2002-7004931 was disclosed
another method which used a corrugated tape for the individual filter
wrap 22a to wind the filter segment 21b.
When it comes to the filter material 21, cellulose acetate solutions are
most commonly used in the current market, and a method of enlarging
the surface area of a filter in order to increase the condensate retention
capacity of the filter or of using the cellulose mixed with materials other
than acetate, micro-fibril, paper, and non-woven fabric has been
developed and adopted for the filter material 21.
Similar fibrous filters made on the cellulose basis have the merit of
efficient production process, visual homogeneity of a cross-section of
the filter, filterability of nitrosamine and phenol, etc., but they also have
a major demerit to be improved: the filtering capacity of a filter is limited
and defined by the draw resistance and the physical specifications for the
composition of the filter. That is, the filtering capacity of a specified
filter (measured by the nicotine and tar retention capacity) is defined by
the draw resistance of the filter and the density of the fabric used, and
there is no way of maintaining the requir ements for a filter's length,
diameter, draw resistance, the density of the fabric used, and so on, and,
at the same time, increasing the filtering capacity of the filter. As the
filtering capacity of a filter increases, so does its draw resistance.
And the size of a filter can not be indefinitely enlarged in order to
increase the filtering capacity and the condensate retention capacity of
the filter.
As described above, there is a limit in the condensate retention capacity
and the particle filtering capacity of the filter material itself.
Therefore, the reliance on the filter material only can not eliminate the
noxious substance of cigarette smoke like nicotine, tar, and so on, and
the problem still remains, threatening the smoker's health.
As the filter material alone can not eliminate such a limit in the
condensate retention capacity and the filtering capacity of a filter,
methods of putting various agents into the filter rod 2 have been devised
in order to complement such a limit; a process of putting agents in a
chamber formed either between the filter segment 21a and 21b or in
other position, and a process of putting and dispersing agents inside the
filter segment 21b.
2
CA 02525128 2005-08-02
WO 2004/068975 PCT/KR2004/000206
The agents so devised that can be used for the filter material 21 cover a
variety of minerals, plants, and chemical materials such as carbon
powder, silicon dioxide, zeolite, various metals, metallic oxide, green tea
powder, aromatics, salt roasted in bamboo, pine resin, artemisia, various
medical herbs, and so on, most of which, except a few like activated
carbon powder, are not actually used in the market because of the
increase in manufacturing expense, difficulties in improving the product
value accordingly to the increase of the manufacturing cost, the
uncertainty of the effectiveness, and so on.
Even the added carbon powder is just supplementary, not enough to
bring about a significant effect for the elimination of noxious substance.
Thus, there exist no filter cigarettes in the market safe from the noxious
substance from cigarette smoking because of the limit in the filtering
capacity of the filter. This is obvious up-to the present.

[Technical Problem]
From the past, a rather effective way of protecting the smoker's health
from hazardous cigarette smoking has been proposed the use of a
cigarette pipe exterior to the cigarette. People have been using a
cigarette pipe mainly for convenience or style, but when they clean a
cigarette pipe used for a while, nat to mention a long smoking pipe, they
can see a great deal of the noxious substance or so-called tobacco tar
stick to the pipe, which is the result of the cigarette smoke colliding and
sticking while going through a long pathway. Imperfect as may be, a
cigarette pipe does a rather effective role for filtering in itself.
In Japan PAT'61~'~~1, Japan Utility Model Publications Sho4$-56135,
Korea Utility Model Publications U1935-1337 (Fib. 2), and others, was
disclosed a cigarette pipe in which is inserted a device that, utilizing the
phenomenon of the collision, condensation, liquidation, and adhesion of
the cigarette smoke, induces the cigarette smoke to go through a
plurality of holes and collide, as described above, thereby enabling to
effectively extract tobacco tar, and such cigarette pipes have been
produced on a commercial scale and distributed in the market up to the
present. The use of a tar eliminating cigarette pipe as such is a very
effective way to overcome the limited filtering capacity of a filter
cigarette.
However, in spite of the merit of protecting the smoker's health from
cigarette smoking by filtering one more time the noxious substance of
the smoke which, otherwise, would have been inhaled into the smoker's
5
CA 02525128 2005-08-02
WO 2004/068975 PCT/KR2004/000206
body, a cigarette pipe has the demerit of not being widely used for the
various negative reasons, such as the troublesome use, the
inconvenience of carrying, the rejection of the smell of nicotine,
additional expenses, etc..
Also, in the past were introduced techniques of inserting into the filter
cigarette a device for extracting noxious substance by inducing the
cigarette smoke to collide: In Korea Utility Model Publications 72-1150
was disclosed °°A Nicotine Eliminating cigarette dap Device", in
which
such a device is inserted between the filter rod and the tobacco rod, and
in Patent Publications PAT1997-8066 (Fig. 3) was disclosed "An
Adsorptive opening for Cigarette Filter" in which a separable upper body
[(C) of Fig. 3] with the holes formed therein for the smoke to pass
through and a separable lower body [(D) of Fig. 3] with the walls for the
smoke to collide against can be joined together. But these two techniques
can hardly be commercially applicable because of numerous problems
the two-body composition's negative effects on the production process
and efficiency, the loss of the productivity in inserting the front end and
the rear end of the filter as designated, the smoke inflow opening being
clogged in case of adopting a charcoal filter, tearing-off of the filter rod
~ at the two dividing lines between the filter segment and the inverted
device, and so on.
[Technical Solution 1_
The present invention acknowledges that the method of either relying on
the filter material or of putting various agents into the filter has an
ultimate limit in the filter cigarette and is, therefore, intended to
overcome such a limit fundamentally by a filter device that can
effectively extract noxious substance.
~ther subject of the present invention is to make feasible in terms of the
production process, the manufacturing cost, the function of the filter, and
so on, the formation of such a filter device inside the filter, thereby
enabling its commercial application with ease.
Another subject of the present invention is to enhance the product value
of the filter cigarette in the filter of which agents are put or a device is
inserted for the extraction of noxious substance so that the consumer
can easily recognize such a filter cigarette in the market.

Fibs. 4(A), (B), (C), and (D) illustrate a transparent filter for the
extraction of noxious substance according to the present invention 5
(hereinafter called extraction filter)'>

smoke
(C) is a perspective side view;
(D) is a frontal view.
A rear view of the extraction filter 5 is identical with the frontal view.
B indicates a place where noxious substance is deposited. One position
only is shown for the simplification of the drawing. The marking of the
identical codes is omitted. All drawings attached were drawn in outline
for the sake of understanding. The arrow signs of the drawings indicate
the direction of the flow of the smoke, and the arrow signs vertical
toward the filter rod 2 indicate the inflow of the outside air from the
ventilation holes.
From here on, the composition and the resulting function and effect of
the present invention will be described in details with reference to the
attached drawings.
In a conventional filter device which induces the smoke to collide to
extract noxious substance, regardless of whether the filter device is
placed in a cigarette pipe or inserted inside a filter, there are two
separated bodies; the upper body where there are a number of the
smoke inflow openings 53 and the lower body where there are a number
of the smoke colliding walls 54, but, in the extraction filter 5, the smoke
inflow openings 53 and the smoke colliding walls 54 are formed in a
same body and installed in both the entrance side 53 and 54 and the exit
side 53' and 54' of the smoke.
The monolithic composition in which the smoke inflow openings 53 and
the smoke colliding walls 54 constitute the same body as such is a very
important factor for a high efficiency of the filter producing process.
Besides, all conventional filter devices have a fixed direction of the
7
CA 02525128 2005-08-02
WO 2004/068975 PCT/KR2004/000206
smoke inflow for the compositional reason, therefore, if the insertion of
the filter device is reversed, it can no longer work, whereas the
extraction filter 5 can extract the noxious substance of the smoke,
regardless of whether the smoke flows in through the front end or the
rear end of the extraction filter 5.
In a highly automated modern facilities of manufacturing the filter rod 2,
it is extremely difficult, though not impossible, to make sure of manually
inserting the lower body into the upper body without making errors,
especially when both the front and the rear of a filter device are of a
l0 shape, therefore, not easily recognizable.
~T he monolithic composition of the smoke inflow openings 53 and the
smoke colliding walls 54 in the same body in order to improve the
productivity in manufacturing the filter rods 2, and the arrangement of
the smoke inflow openings 53 and the smoke colliding walls 54 in both
front and rear of the body constitute an important factor for the present
invention, which can never be emphasized too much.
The extraction filter 5, in which the smoke inflow openings 53 and the
smoke colliding walls 54 constitute the monolithic body and the insertion
of the filter can be either from the front or from the rear of the body, can
be manipulated like the filter segments 21a and 21b, and respond to a
high speed of the machine rolling up the filter rod wraps 4 to wind each
filter segments integrately, even without a separate facilities or a
process.
The smoke inflow openings 53 of the extraction filter 5 are of a long,
narrow quadrangular shape, and the smoke inflow openings 53 are
formed inside around the inner circumference of the extraction filter 5,
as shown in Fig. 4(D).
The conventional filter device for extracting noxious substance by the
smoke collision has an upper body with a plurality of small holes for the
smoke inflow, but there is no reason why the shape of the smoke inflow
opening should be circular.
The smoke inflow opening 53 of a quadrangular shape, as shown in Fig. 5
(E), can also induce the smoke inflow to converge and collide, enabling
the particles contained in the maisture of the smoke to easily adhere to
8
CA 02525128 2005-08-02
WO 2004/068975 PCT/KR2004/000206
the wall against which the smoke collides.
Besides, such quadrangular shape of the smoke inflow opening 53 serves
the purpose of the various application of the extraction filter 5 inside the
filter rod 2.
Also, in the present time, most of the filter cigarettes have a dual filter
composition, and, in many cases, activated carbon or other agents are
added and dispersed, in which case the powders of the agents are likely
to clog the smoke inflow holes, causing difficulties in the composition of
a cigarette with a filter device inserted. The smoke inflow openings 53 of
a long, narrow quadrangular shape can solve such problem.
Also, such quadrangular smoke inflow openings 53 enable to position the
extraction filter 5 in the end of the filter rod 2 toward the tobacco rod 1.
Agents or tobacco fillers 11 (if small, it can pass through) can hardly clog
or block a whole narrow but Iong quadrangular smoke inflow opening 53
shaping like a net to filter out the impurities to prevent a gutter from
being choked and curving around the circumference of the extraction
filter 5. If the said smoke inflow opening 53 is partially clogged or closed,
the smoke, without being held up, detours the clogged or closed part of
the said smoke inflow opening 53 to pass through.
Also, such a shape of the smoke inflow opening 53 alleviates draw
resistance. If an equal area being installed for the air inflow, the draw
resistance of a filter with a number of the smoke inflow openings 53 of a
long quadrangular shape is Iess than that of a filter with a plurality of the
small holes.
Further, as shown in Fig. 4(D), the smoke inflow openings 53 are
installed within the ventilation area of the diluted air inflow openings 5~
between two neighboring filter holders 51.
The position of the smol~e inflow openings 53 as such enables the air
flowing in through the diluted air inflow openings 52 to immediately
collide with the smoke inside.
Furthermore, the smoke can pass and collide at the two corners of the
smoke inflow openings 53 faster than through the round holes, thereby
enhancing the effect of extracting noxious substance.
To further enhance the extracting effect, another smoke colliding wall
54' is formed, as shown in the circle of Fig. 4(B), so that the smoke may
9
CA 02525128 2005-08-02
WO 2004/068975 PCT/KR2004/000206
first collide against the smoke colliding wall 54, and another smoke
colliding wall 54'one more time.
The filter holders 51 do not surround the whole filter segments 21a and
21b like a tube, but are separated. In most cases, the filter holder blocks
the periphery of the filter disc, causing a problem of being unable to
utilize the periphery of the filter disc. The separated filter holders 51 can
solve such a problem, and the narrower the area of the filter holders 51
and the Less the number of the filter holders 51 is, the better.
Besides, the number of the filter holders 51 differs, as shown in Fib. 4(A)
and (D), which means that the extraction filter 5 can have various
numbers of the filter holders 51 and the smoke inflow openings 53.
The number and the size can be properly increased or decreased
according to the draw resistance, the effect of extracting noxious
substance, the efficiency of the production process of winding the filter
segments 21a and 21b together, and so on.
The diluted air inflow openings (Ventilation Area) 52 are arranged beside
the filter holders 51.
The diluted air inflow openings 52 bring about a new working effect
interactively in connection with the ventilation holes 31.
The effect of the ventilation holes 31 is obvious. It guarantees the
smoker for the more purified smoke and the reduced amount of smoke
inhalation.
On the other hand, the conventional filter device dominantly relying on
the ventilation holes has the disadvantage not only of "air taste" but also
of the inability to utilize the filtering capacity of the periphery of the
filter disc. Recent techniques were devised to enhance the effect of
ventilation holes and solve the disadvantage mentioned in the above, but
to fail to meet the expectations: Korea Patent Office Application No. 10
2001-70051'78 was intended to solve the disproportion of the air inflow
ratio between the ventilation holes and the inside filter, but was unable to
solve the disadvantage of the ventilation holes mentioned in the above,
and Korea Patent Office Application No. 10-2002-7004931 still left the
problem of °°air taste" unsolved.
The diluted air inflow openings 52 of the extraction filter 5 can bring
about a working effect of diluting the smoke by air in connection with the
CA 02525128 2005-08-02
WO 2004/068975 PCT/KR2004/000206
ventilation holes, thereby solving the disadvantage of the ventilation
holes.
Because the smoke flow in parallel with the direction of the fiber, the air
flowing in through the ventilation holes mostly fails to mix with the
smoke passing through the inside of the filter, flows in its periphery of
the filter disc, then is inhaled into the smoker's mouth. Only the amount
of the smoke can be reduced but most of the smoke is mixed with air
inside the smoker's mouth. hs a result, what the consumer call "air
taste" causes a loss of the cigarette taste.
On the other hand, the smoke flowing in the periphery of the filter disc,
being i~locl~ed by the air flowing in through the ventilation holes, brings
about a phenomenon of converging toward the center part of the filter,
and most of the air inflowing from the outside flow in the periphery of
the filter disc, so the filtering capacity of the periphery of the filter disc
can not be fully utilized. The periphery of the filter disc that is not
utilized for the filtration occupies a significant portion of the whole
filter,
though the portion varies depending on the position of the ventilation
holes to be installed.
In case of the extraction filter 5, the air flowing in through the diluted air
inflow openings 52 from the outside collide with the smoke flowing inside
the extraction filter in the empty space of the extraction filter 5, which
creates a new effect of the smoke being perfectly diluted by the air,
thereby solving the disadvantage of the ventilation holes mentioned in
the above.
The smoke and the air do not flow separately, but the smoke perfectly
diluted by the air pass through evenly.
Therefore, the loss of the cigarette taste due to "air taste" can be
eliminated, the disproportion of the air inflow ratio can be corrected, the
filtering capacity of the periphery of the filter disc can be utilized, a
phenomenon of the inside smoke converging toward the center can be
prevented, and the perfectly diluted smoke can stop what the cigarette
dealers call "hot collapse', that is, a decrease in the degree of hardness
of a filter because of high temperature.
Besides, the diluted air inflow openings 52 can also be installed in the
position of X52') of dig. 4f~1), and, accordingly, there are three positions
available the diluted air inflow openings 52 installed toward the entrance
11
CA 02525128 2005-08-02
WO 2004/068975 PCT/KR2004/000206
of the smoke, the diluted air inflow openings 52 installed toward the exit
of the smoke, and the diluted air inflow openings 52' installed toward the
middle. Depending on the choice of a position for the installation of the
ventilation holes, filter cigarettes of various flavors (tastes) can be
manufactured.
The flow barriers 55 prevent the exit of the smoke located in the
opposite side from being clogged by the extracted noxious substance B.
A space is formed where noxious substance stays, stretching after the
direction of the smoke inflow, but the flow barriers 55 block the
stretching, therefore it possible to design shorter the entire length of the
extraction filter 5.
The flow barriers 55 form a belt following the circumferential direction
of the extraction filter 5, but ribs of a fan in case of composing the
extraction filters as shown in F ig. 5 (F:).
Fig. 5 shows other actual examples of the extraction 5.
All the drawings are fragmentary cross-sectional views of the cylindrical
extraction filter 5 cut in half.
Fig. 5(A) illustrates that the smoke colliding wall of the extraction filter 5
of Fig. 4(B) is turned outside, in which case the extracted noxious
substance B of Fig. 5 (A) is deposited in the outside of the cylindrical
body. Fig. 5(B) illustrates that the place depositing the noxious substance
of Fig. 5(A) can be deleted and the entire length of the filter is shortened
thereby. Such a composition enables to design the length of a filter as
shortest as possible.
Also, the composition shown in Fig. 5(B) enables to install the smoke
inflow openings 53 as shown in Fig. 5(h) (a frontal perspective view
illustrating that the smoke inflow openings 53 are installed toward the
center of the circle lengthwise).
In the actual example of Fig. 5(A), the smoke flows in the exterior of the
extraction filter, and, therefore, the periphery of the extraction filter disc
can be utilized for a ventilation area. In case of Figs. 5(B) and 5(C), the
middle area of the extraction filter can also be used for a ventilation area.
Figs. 5(C) and (D) illustrate the Figs. 4(A) and 5(A) cut in half,
respectively, in which the smoke flows in one direction only. A diluted air
12
CA 02525128 2005-08-02
WO 2004/068975 PCT/KR2004/000206
inflow opening is indicative of the front and rear of the filter, therefore,
if
a machine or facilities can recognize the diluted air inflow opening and
treat the front and rear of the filter properly, the filter cigarette with a
shorter length of the extraction filter 5 can be manufactured. All other
actual examples of the extraction filter 5 have the monolithic composition
in which the smoke inflow openings 53 and the smoke colliding walls 54
constitute the same body.
T he extraction filter 5 suitable for the diameter of any and all of the
conventional filter cigarettes (slim type included) can be manufactured,
and there is no problems in properly adjusting within the filter rod 2 all
the specifications for each parts and sections of the extraction filter 5
according to the flavor, quality, and design of the filter cigarette to be
targeted and produced.
T he extraction filter 5 can be made of petrochemical material of a plastic
kind by a refined metallic mold or of highly refined starch easily soluble
in water. It is desirable to use material of outstanding solubility in the
environment. T herefore, further studies are needed to improve both the
cellulose acetate filter hardly soluble in the environment and the
extraction filter 5.
The extraction filter 5 is made transparent, which, in connection with the
important compositional factors of the present invention, generates a
new visual effect and economic effect as well.
Fig. 6(A) is a view of an anatomy of a transparent extraction filter
cigarette 10 according to the first embodiment of the present invention at
a viewing angle.
In order to show the customer the effect of the extraction filter 5, the
present invention adopts a transparent filter rod wrap 4 to wind the filter
segments Zla, Z1b and the extraction filter 5 integrately, forming a filter
rod 2, and a tipping paper 6, the transparent part of which winds the
transparent filter rod wrap 4, to connect the tobacco rod 1 to the filter
rod ~, thereby completing a filter cigarette 10 with the extraction filter 5
being inserted in the filter rod 2 and visible to the naked eye.
To conform to the purpose of making the interior of the filter visible,
significantly transparent paper and non-woven fabric or petrochemical
materials of films or tapes of a bind, or other materials are good enough
13
CA 02525128 2005-08-02
WO 2004/068975 PCT/KR2004/000206
for the material that can be used for the transparent filter rod wrap 4 and
the partially transparent tipping paper 6.
To solve the ventilatory problem of the materials other than non-woven
fabric, a number of the ventilation windows 41 were installed, the area of
which is larger than the area of the ventilation holes 31 and a ventilation
window is perforated bigger than a ventilation hole.
The installation of the ventilation holes has prevailed for the
conventional filter cigarette so dominantly that such a wrap mentioned in
the above seems to be hardly adopted to improve the ventilation, but
even if adopted, that is, a filter rod 2, for instance, composed only of the
filter segments 21a and 2~b is wound by the transparent filter rod wrap 4
on which the ventilation windows 41 of the present invention are formed,
the disproportion of the air inflow will occur between the holes of such a
place where the air passes straight through the ventilation windows 4~,
the diluted air inflow openings 52, and the ventilation holes 31 and the
holes of the place otherwise. However, such a problem does not occur in
the filter cigarette ~.0 of the present invention because the air ventilates
in the empty space of the extraction filter 5.
Being connected interactively with the extraction filter 5 made
transparent, the transparent filter rod wrap 4 and the partially
transparent tipping paper 6 synergistically bring about an effect of
visually differentiating the filter cigarette of the present invention from
the others and enhancing its product value.
As shown in 30 of Fig. 10, a filter cigarette, being composed of the
partially transparent filter rod 2 which the transparent filter rod wrap 4
and the partially transparent tipping paper E~ constitute, and combined
with a filter cigarette which either contains agents or a device effective
for the elimination of noxious substance, will certainly enhance the
product value of such a filter cigarette.
No matter how effective agents or the device as such may be, if the
adoption of the agents or the device can not bring about an increase in
the acceptability of the consumer and the resulting economic effect, it is
difficult for the invention as such to develop into a commercial product
that can reach to the consumer. This is why many antecedent
developments of a filter cigarette failed in penetrating into the market, in
14

spite of its effective agents or device as such.
It is a progressive inventive behavior to cope with prior failure, and make
sure of a high productivity and product value from the initial stage of the
product development.
T he present invention, being composed of the transparent filter rod wrap
4, the partially transparent tipping paper 6, and the partially transparent
filter rod 2, is intended to cope with such prior failures that many filter
cigarette developments by the conventional technique had to face in
penetrating into the market, and enlarge the acceptability of the
consumer for the filter cigarette.
Seeing the result, the stiff stuff deposited inside of the filter rod, the
consumer can actually realize the extracting effect of the noxious
substance.
The visible is to the invisible what a TV is to a radio, and seeing is
believing.
Fib. 6(B) shows a transparent filter rod wrap 4. The perforation of the
ventilation windows 41 is undertaken by laser or other processes, and
the ventilation windows 41 are formed before the roller is wound by the
wraps.
Fig. 6(C) shows a partially transparent tipping paper 6. 6a is an opaque
tipping paper, the mouth end segment of the tipping paper 6, and 6b is a
transparent part. The opaque tipping paper 6a softens the feeling when
the smoker puts it in the mouth and beeps an esthetic sense, and 6b can
be of less transparent color to moderate the rejection of the noxious
substance and keep an esthetic sense.
The two slant parallel lines show the joints of 6a and 6b.
Also, as shown in Fib. 6(D), the entire tipping paper 6 is made of
transparent or significantly transparent material.

cigarette 10 according to the first actual example of the present
invention.

Fig. 8 illustrates a composition of a filter cigarette that omits a
transparent tipping paper 6. Figs. 8(A), (B), (C), and (D) all show the
application of other actual examples of the extraction filter 5. The
composition of a filter cigarette, as shown in Figs. 8(A) and (D), enables
to manufacture a cigarette of a soft filter, so unique that the part of
depositing the noxious substance can be pressed by a finger.
Also, it is possible to compose a filter cigarette omitting the second
individual filter section, 2Lb+ 22b because of the smoke inflow openings
53 of the extraction filter 5 can keep the entrance from being clogged by
l0 the cigarette filler 11.
Further, in case where the extraction filter is composed as shown in Figs.
8(C) and (D), the first individual filter section, 21a+ 22a can be omitted,
and the part of the filter holder 51 of the extraction filter, the mouth end
of the filter can be formed flat so that it can be put in the mouthed.
Fig. 9 shows a composition of the extraction filter 5' adopting fibrous
mzcro pore.
As described in the above, the extraction filter 5 can be manufactured
variously according to the features of the targeted filter cigarette and the
size of the filter material.
Fig. ~~(A) illustrates a view at a viewing angle of the exterior of a
transparent extraction filter cigarette 10 in which is inserted an
extraction filter 5 according to the first embodiment of the present
invention.
Fig. 10(B) illustrates a view at a viewing angle of the exterior of a
transparent micro pore extraction filter cigarette 20 in which is inserted
a transparent micro pore extraction filter 5' according to the second
embodiment of the present invention .
Fig. 10(C) illustrates a view at a viewing angle of the exterior of a
transparent filter cigarette 3U containing in the filter rod 2 various agents
visible from the outside according to the third embodiment of the present
invention.
In the above, for the explanation's sake, the composition of the present
invention and the resultant function and effect were described together.
In summary, the effect of the filter cigarette of the present invention is

clear and diverse.
The composition, in which a number of the smoke inflow openings 53 and
a number of the smoke colliding walls 54 of the extraction filter 5 of the
present invention constitute a same body and the direction of the
extraction filter 5 is reversible, enables not only for the industry to
easily adopt the extraction filter 5 of the present invention, but also to
overcome the limit of the nicotine filtering capacity and the condensate
retention capacity of the conventional fabric filter, thereby protecting the
smoker's health.
The noxious substance extracted by the extraction filter 5 in the form of
nicotine minus the filtering capacity of the volume of the fibrous filter
equivalent to the volume that the extraction filter occupies in the filter
rod would have been stick to the smoker's mouth, nasal mucosa, and/or
lung.
A new effect of diluting the smoke through the diluted air inflow openings
5~ of the present invention was described Together with the composition
of the present invention in the above.
The filter cigarette 30 of the present invention, being composed of the
filter rod 2 a part of which is transparent, will improve the product value
of various chamber filter cigarettes containing effective agents for the
extraction of noxious substance, and bring about the econamic effect of
enlarging the acceptability of the consumer.
Also, the present invention enables to manufacture the kind of filter
cigarettes which can eliminate various kinds of noxious substance.
.~ or instance, if there is a special kind of noxious substance that can not
be extracted by the extraction filter 5, then it is possible to put in the
interior space A of the extraction filter 5 some agents that can filter such
bind of noxious substances, and, combining the merit of the chamber
filter and that of the instrumental extraction filter, provide the customer
with the less harmful filter cigarette.
liurther, it is necessary to continue to study ,and ultimately develop the
kind of the enhanced and advanced filter cigarette safe from the lung
disease and other diseases.
