Description

Filter Cigarettes {Extraction And Transparent Filter Cigarette}

Referring to the accompanying drawings, a typical filter cigarette is a tobacco rod (1) and

Filter rod (2) and clip paper (3) for fixing and connecting these two parts

Consists of.

In more detail, in the dual filter structure, as shown in Fig. 1, two separate filter materials are shown.

21a, 21b are wound by respective individual windings 22a, 22b, again

These filter materials 21 are integrated and wound up by the filter rod winding sheet 23,

Cigarette rod (1) consisting of a tobacco filler (11) and the winding paper (12) surrounding the

It is wound again by the clip paper (3) which connects and a filter cigarette

It is composed.

Today, the dangers of tobacco are widely recognized by consumers.

To minimize the adverse effects on the human body from filter cigarettes

To increase the functionality of the filter as well as improving the quality of the

Various methods are being taken.

Look at the wrapping papers 22a, 22b and 23 surrounding the filter material.

Paper or non-woven fabrics are used, which determine the amount of smoke inhaled.

As a means of introducing air from the filter side

Ventilation hole (31) with fine opening of clip paper

For good ventilation inside the filter.

In order to increase the ventilation between the ventilation hole and the internal filter,

Korean Patent Office Application No. 10-2001-7005178

Using a paper with embossed embossed paper as the filter rod winding (23)

It is disclosed, and the Republic of Korea Patent Application No. 10-2002-7004931

The filter material was formed by using the tape formed with an S-shaped groove as the filter individual winding sheet 22a.

A method of enclosing is disclosed.

Looking at the filter material 21, in the current market cellulose [Cellulose]

The filter material produced using acetate solution is the most used

Surface area of the filter to increase the condensate retention of the filter.

Cellulose and other materials, microfibers, paper, nonwovens

The degree is developed and used as a filter material.

Similar fibrous filters made on the basis of cellulose are used in the production process.

High efficiency, visual homogeneity of filter cut surface, against nitrosamines and phenols

It has the advantages of filtering, but it has a big disadvantage to be improved.

The filtration capacity of the filter depends on the suction resistance

That is, it is limited and limited by the physical specifications of the filter structure.

That is, the filter capacity of a filter having a certain size (by the retention of nicotine and tar

Is measured by the filter's suction resistance and the fiber density used.

It is prescribed. Maintain specifications such as filter length, diameter, suction resistance and fiber density.

There is no way to increase the filtration capacity of the filter.

Increasing the filtration capacity of the filter also increases the suction resistance.

Infinite filter sizes to increase filter capacity and condensate retention

It cannot be raised.

As such, there is a limit to the condensate retention and the particle filtration capacity of the filter material itself.

It is.

Therefore, only dependence on the filter material is still in the smoke

There are harmful substances such as nicotine and tar, which threaten the health of smokers.

will be.

These filter materials alone have limited condensate retention and filtration capabilities.

In order to compensate for this, a method of adding various substances in the filter rod 2

It is designed. Between the filter material 21a and the filter material 21b or in a separate chamber

[Chamber] is provided to include an additive or dispersed inside the filter material 21b.

It is a method of adding. Additives designed for use in filters

Carbon powder, silicon dioxide, zeolite, various metals, metal oxides, green tea powder

Fragrance, bamboo salt, rosin, mugwort, various herbs, minerals, plants, chemicals, etc.

It covers, but except for a few such as activated carbon powder

The increase in manufacturing costs and consequently the increase in marketability and the effect of its use

Uncertainties are not being used in the real market.

In addition, added carbon powder is a secondary means to remove harmful substances.

It is not enough to show a great effect.

As above, the filter for all filter cigarettes currently used in the market

Due to limitations in capacity, it is safe from numerous harmful substances

There is no filter cigarette. This is evident to date.

From the past, very effective to protect health from the harm of cigarette

A method has been proposed. It externally smokes tobacco pipe against tobacco

Is to use. It has been used for convenience or fashion, but daringly long

Even if it's not a cigarette pipe,

Smoke collides through long passages, and sticks up quite a bit

Toxic substances, also known as cigarette clings can be seen.

It's not perfect, but it's a great filter.

Tobacco smoke is based on the collision, liquefaction, and sticking of the cigarette smoke.

Effectively inserting a cigarette into the hole

Tobacco pipe designed for extraction is Japan PAT617721, Japan

Publication 48-56185, Republic of Korea Utility Model Room 1985-1337 (Fig. 2), etc.

It has been commercialized and commercialized and is currently on the market.

The use of these nicotine removal pipes overcomes the limited filtration capacity of filter cigarettes.

It is a very effective way.

The use of such a device reconstructs harmful substances that can be introduced directly into the human body.

Despite the benefits of filtering once to protect the health of smokers

Troublesome use, inconvenience of carrying, resistance to cigarette smell, additional

There is a disadvantage that the occurrence of the cost is not used widely because of the negative action.

In addition, in the past, such a cigarette smoke to extract harmful substances

A technique for inserting a device into a filter cigarette is disclosed.

The Republic of Korea Utility Publication 72-1150 is inserted between the filter rod and the tobacco rod

A nicotine removal tobacco cap device is disclosed and Japanese Patent Laid-Open No. 1997-8066

(Fig. 3) shows the upper body (C in Fig. 3) where the through hole of the smoke is formed and the

The lower body (d in Fig. 3) in which the collision surface is formed can be separated and joined.

"Hazardous material adsorption for tobacco filters" is disclosed, but both

The problem of production process and efficiency due to the structure of the body

Productivity problem to be inserted, postponing the adoption of Charcoal Filter

Blocking of inlet hole, winding paper and clip paper surrounding filter material and insertion device

It is a schematic cross section showing the flow

Fig. 4C is a side perspective view and Fig. 4D is a front view.

The rear view of the extraction filter 5 is the same as the front view.

B indicates where the extracted hazardous substances accumulate. Show drawings briefly

Only one side is shown for the sake of simplicity. The same sign is omitted.

All the accompanying drawings are schematically illustrated in order to facilitate understanding.

Arrows in the drawing indicate the direction of flow of smoke and perpendicular to the filter rod

The arrow pointing indicates the inflow of external air from the ventilation hole.

Hereinafter, with reference to the drawings in detail the configuration and its operation and effects of the present invention

Explain

A device for extracting harmful substances by colliding conventional smoke is a tobacco pipe.

The upper body with smoke inlet, whether in the

Two parts are separated into the lower body with a smoke bump, but in the present invention

In the extraction filter 5 by the smoke inlet 53 and the smoke collision jaw 54 to one body

On both the inlet (53, 54) and outlet (53 ', 54')

It is installed.

The smoke inlet 53 and the smoke collision jaw 54 is integrated into one body

The structure is of great importance for the high efficiency of the filter production process.

In addition, all the conventional extraction apparatus, due to its structure, one side smoke inflow

Has a direction, and if the direction is changed back and forth, no harmful substances can be extracted.

Extraction filter (5) of the present invention is to remove harmful substances when smoke flows in either front or back

Can be extracted.

In the production facility of modern automated filter rods (2)

I put it in, and the front and back appearance is the same, and it is not easy to distinguish a device, and distinguish direction

Inserting inside the filter is not impossible, but

It becomes a difficult problem to use.

In order to improve the productivity of the filter rod (2), the smoke inlet 53 and the smoke collision jaw (54)

Structure formed of one body and smoke inlet 53 'installed on both sides and smoke

The impact jaw 54 'of the present invention extraction filter 5 cannot be overemphasized.

Is an important component of.

The smoke inlet 53 and the smoke collision jaw 54 are integrated into one body,

Extraction filter 5 of the present invention that can be inserted in the direction is a separate production equipment

I can be treated the same as the filter material (21a, 21b) even if not

It can correspond to the production speed that is processed at high speed in the filter rod hoist.

Smoke inlet 53 of the extraction filter 5 according to the present invention is a narrow and long rectangular

It is shaped and curved along the outer circumference of the extraction filter 5.

Conventional devices for extracting harmful substances by collisions are all shaped like holes.

It has an upper body with smoke inlet, which is used for

Extraction is not necessarily through the shape of the hole.

As shown in Fig. 5E, the smoke inlet 53 concentrates the smoke even in a rectangular shape.

When colliding, particles contained in the moisture of the smoke sufficiently adhere to the impact surface.

The square smoke inlet 53 is a filter rod (2) to the extraction filter 5 of the present invention

To apply variously inside.

Most modern filter cigarettes have a dual filter structure so that activated carbon or other

In many cases, additives are dispersed and added.

This smoke inlet is blocked by the powder of additives, so

There is a problem that is difficult to form a filter cigarette.

The narrow and long rectangular smoke inlet 53 is formed to solve this problem.

In addition, the smoke inlet 53 of this type is the filter rod of the extraction filter 5 of the present invention

Allow it to be located at the end of the tobacco rod (1) side of (2).

It is shaped like a mesh that prevents impurities from blocking sewage holes.

Narrow and long curved along the circumferential direction of the extraction filter (5)

Square smoke inlet (53) is sandwiched with additives or tobacco filler (11)

If you block it (it will pass through it), the inlet

As it forms, smoke can pass through without clogging.

This shape of the smoke inlet 53 also eliminates suction resistance.

Suction resistance received from several holes when installing the same oil inlet

Longer squares are more advantageous for suction resistance.

In addition, the smoke inlet 53 is to avoid the filter support step 51 as shown in Figure 4 (D)

It is installed in the ventilation area of the dilution air inlet 52.

This position of the smoke inlet 53 is the air introduced from the dilution air inlet 52

It allows you to collide directly with the smoke inside.

At both corners of the smoke inlet 53, the smoke flows at a higher speed than the circular one.

It collides with each other to increase the extraction effect of harmful substances.

In addition, in order to further enhance the effect of extracting harmful substances, smoke is applied to the smoke collision jaw (54).

Install a second smoke collision sill at the entrance where it collides with the smoke.

It collides with each other to improve the effect of extracting harmful substances.

The filter support jaw 51 does not support all the outer periphery of the filter material 21a, 21b.

They are installed apart from each other. This is because the filter base 51 is formed of the filter material 21a, 21b.

To solve the disadvantage of not using it by blocking the periphery

As the area and number are smaller, the smaller the better.

In addition, the number of the filter support jaw 51 of FIG. 4A and the filter support jaw 51 of FIG.

It is shown differently, in the extraction filter 5 of the present invention as described

The number of 51 and the smoke inlet 53 is not limited.

Efficiency and suction resistance of the production process wound with the filter material (21a, 21b)

In consideration of the extraction effect of hazardous substances, etc.

You can add or subtract.

Dilution air inlet [Ventilation Area] (52) is the filter base (51)

It is located next to it.

The dilution air inlet 52 is organically combined with the ventilation hole 31 to form a new

It has an effect.

The effect of the ventilation hole is obvious.

Ensure smokers have milder smoke and reduced smoker smoke.

On the other hand, the disadvantage of not using the "air flavor" and the filtering ability around the filter

have. The technology to enhance the effect of this Ventilation Hall and block the disadvantages

Although the latest one, the Republic of Korea Patent Application No. 10-2001-7005178

To solve the non-uniformity of the air inflow rate between the ventilation hole and the internal filter.

It does not solve the shortcomings of the Ventilation Hall as above.

Korean Patent Office Application No. 10-2002-7004931 excludes "air flavor"

There are no drawbacks.

The dilution air inlet 52 of the extraction filter 5 according to the present invention is combined with a ventilation hole.

Ventilation with a new effect of diluting smoke and outside air

Eliminate the disadvantages of the hall.

Smoke passing through the filter material flows in parallel in the direction of the fiber

Most of the air coming from the ventilation hole passes through the inside of the filter.

It doesn't mix with the smoke and flows around the filter

Enter It only reduces the amount of smoke that is inhaled,

It can be said to be mixed. This is why it is called "air flavor" by consumers

This results in impaired taste of the tobacco being called.

On the other hand, the smoke flowing through the filter periphery is the

Blocked by the filter, causing the phenomenon to concentrate in the center of the filter.

Outside air is mainly flowed to the periphery, whereby the filtration capacity of the filter

I can't use it. It depends on where you install the Ventilation Hall.

But this unusable portion of the filter

The share is quite high.

In the extraction filter 5 according to the present invention from the outside through the dilution air inlet 52

Inflow of air collides with smoke flowing inside and empty space in the extraction filter (5)

The new effect is that the internal smoke and external air are completely diluted.

Can solve the above problems of the ventilation hole.

Smoke and air do not flow separately, but completely diluted smoke

Pass through the whole.

Therefore, it eliminates the "air flavor" and prevents the tobacco taste from being damaged.

There is no need to worry about unevenness and you can take advantage of the filtration capabilities around the filter

This prevents the smoke passing through the inside from concentrating on the filter center.

, And the fully diluted smoke has a low temperature, which is why it

Collapse] "undesirable, which reduces the hardness of the filter, called

The phenomenon can be prevented.

In addition, the dilution air inlet 52 may be installed in the portion 52 'of FIG.

Accordingly, the dilution air inlet 52 or in the middle of the smoke inlet or outlet

Of the three dilution air inlets (52 '), the ventilation hole

Depending on the installation, it is possible to produce filter cigarettes of various smoke flavors (taste).

Flow prevention jaw (55) is the harmful substance extracted from the opposite side of the smoke (B)

To prevent the outlet 53 'from being blocked. Also, the space where the extracted harmful substances accumulate

It is necessary to keep the harmful substances flowing along the direction of the smoke

This makes it possible to design a short overall length of the extraction filter (5).

The flow preventing jaw 55 forms a band along the circumferential direction of the extraction filter 5.

When the extraction filter is configured as shown in FIG.

5 is another embodiment of an extraction filter 5 according to the present invention.

All are schematic sectional drawing which cut | disconnected the circular extraction filter 5 in half.

FIG. 5A shows the secondary smoke collision step of the extraction filter 5 of FIG.

Inverted, in this case the harmful substance (B) extracted to the outside of the cylindrical body

Pile up. Figure 5 (B) is to delete the place where the harmful substance (B) of Figure 5 (A) is stacked

This configuration makes it possible to design the entire length of the extraction filter as short as possible.

In addition, when constituting the extraction filter as shown in Fig. 5B, Fig. 5E (the smoke inlet 53)

As shown in the front perspective view when installed long toward the center of the circle)

Can be installed.

In the embodiment of Fig. 5A, since the smoke flows outside the extraction filter,

This part can also be used as a ventilation area.

In the case of Figs. 5B and 5C, the center of the filter can be used as the ventilation area.

5 (C) and 5 (D) show half the extraction filter configuration of FIGS. 4 (A) and 5 (A), respectively.

The dilution air inlet is formed by cutting off and having only one

It distinguishes front and back, so if you have a separate production facility

The length of the entire extraction filter 5 can be shortened to produce a filter cigarette.

In another embodiment of the present invention, the extraction filter 5 of Figure 5, the smoke inlet 53 and

Smoke collision jaw 54 is installed integrally in one body.

Extraction filter 5 according to the present invention is a conventional all filter cigarettes (including Slim type)

Can be manufactured to suit the diameter of each part.

Filter according to the smoke preference, quality, and design of the cigarette

With the size of the section there is no adjustment in the filter rod (2)

No problem.

Extraction filter (5) of the present invention is a petroleum compound of plastics on a precision mold mold

Made from highly refined starch that can be made and easily decomposed in water

It may be manufactured. Preferably it is made of a material that has high resolution in the environment.

Fabricated and poor in the environment of cellulose acetate filters

The decomposition ability and the decomposition ability in the environment of the extraction filter 5 of the present invention are simultaneously

More research should be done.

The extraction filter 5 according to the present invention is produced transparently.

This, in combination with the important components of the present invention, creates new visual effects and

It brings economic effects.

Fig. 6A is an exploded partial perspective view of the filter cigarette 10 according to the first aspect of the present invention.

In the present invention, in order to show the extraction effect of the extraction device 5 directly to the consumer

Each filter material 21a, 21b and the extraction filter 5 are removed using the transparent filter rod winding paper 4.

Integrated winding to form filter rod (2) and transparent clip paper bonded to paper

(6) is used to connect the tobacco rod (1) and the filter rod (2) to the filter rod (2)

Insertion filter 5 is inserted into the filter cigarette 10 that can be seen from the outside

Completed.

As a material that can be used for the transparent filter rod winding paper (4) and clip paper,

To show the inside of the filter,

Translucent nonwovens and paper or translucent or transparent films, tapes

Transparent or translucent materials are sufficient as petroleum compounds.

The problem of breathability of materials except non-woven fabric is transparent filter rod winding as shown in Fig. 6 (B).

(4) opened relatively larger than the installation area of the ventilation hole 31

This was solved by installing a Ventilation Window (41).

Breathable in typical filter cigarettes, where the installation of the ventilation hall is the mainstream

There is no reason to use such a winding paper for such a problem, but the ventilation of the present invention

With the transparent filter rod winding paper 4 provided with the window 41, only the filter materials 21a and 21b are provided.

In the case of winding the made filter rod 2, the ventilation window 41 and

The dilution air inlet 52 and the ventilation hole 31 do not pass through the same ventilation hole.

Non-uniformity of air inflow may occur between the holes that do not

Since the ventilation in the filter cigarette 10 is made in the empty space of the extraction filter 5

It doesn't matter.

The transparent filter rod winding paper 4 and the transparent clip paper 6 are made transparent.

Organically combined with the extraction filter 5, the filter cigarette 10 of the present invention and other products

To increase the value of goods

Indicates.

Using the transparent filter rod winding paper (4) and the transparent clip paper (6)

Filter cigarette (20 of FIG. 9) harmful substances constitute a transparent part of the filter rod (2)

Enhances the marketability of filter cigarettes with additives or devices effective for removal

It is also a separate invention.

Even if it is an additive or device that is effective for removing harmful substances,

This increases the commerciality of filter cigarettes, increases consumer acceptance and economic effects.

If not, it is developed into a real product and delivered to consumers

it's difficult. Previously developed additives that have a distinct effect on the removal of hazardous substances

Even with the advantage

This is the case for many filter cigarettes that have not penetrated the market.

Overcoming this prior failure and from the product creation stage

Improving the merchandise with the productivity of the product is a progressive invention.

The filter rod (2) is wound with a transparent filter rod winding paper (4) and transparent

It is connected with the tobacco rod 1 by the clip paper 6, and a part of the filter rod 2 is removed.

The visual means of the present invention configured transparently was difficult to penetrate the market.
