Description

Cigarette filter, filter cigarette using the same, and method for producing continuous cigarette filter

The present invention relates to a cigarette filter in which a fragrance or an adsorbent is added in a filter, a filter cigarette using the cigarette filter, and a method for manufacturing a continuous cigarette filter.

For example, a filter rod in which a capsule enclosing a fragrance is added in a filter is described in Patent Document 1 (FIG. 21 of Patent Document 1). This filter rod is obtained by adding capsules to tow at regular intervals and wrapping them. However, in Patent Document 1, the addition position of the capsule may be different every time depending on the stretchability of the tow and the capsule shape, and the stability of the product is lacking. Further, it is impossible to separate the upstream and downstream filters with the capsule as a boundary.

On the other hand, Patent Document 2 discloses a cigarette filter in which a gap is provided in a filter and, for example, the capsule is added to the gap. However, in Patent Document 2, when the consumer crushes the capsule in the air gap, only the portion of the filter itself remains crushed, and the handleability is poor. Moreover, when the fragrance | flavor in a capsule is a liquid, possibility that it will ooze out to the outer side of a filter is high.
On the other hand, Patent Document 3 describes a cigarette filter in which a recess is provided in a filter and the capsule is added to the recess and covered with the other filter. However, in Patent Document 3, it is necessary to provide a recess in the filter in advance, which is troublesome and cumbersome. Moreover, when the shape of a hollow and a capsule does not correspond, a space | gap arises between a hollow and a capsule. Since this space | gap does not have a filtration function, the performance as a cigarette filter cannot fully be exhibited.

The present invention takes the above-described conventional technology into consideration, and can change the type of filter on the upstream side and downstream side with the capsule (additive) as a boundary. An object of the present invention is to provide a cigarette filter that does not bleed out to the outside of the filter when crushing and can obtain a good restoration property, a filter cigarette using the cigarette filter, and a method for manufacturing a continuous cigarette filter. .

In order to achieve the object, in the present invention, a plurality of filter segments arranged in one direction, an additive embedded in a boundary region between the filter segments and used as a fragrance or an adsorbent, and the plurality of filters There is provided a cigarette filter characterized in that the cigarette filter is provided with a molding paper wound around the segments and connecting the filter segments.
As a preferred example, the additive is a capsule in which the flavoring agent or adsorbent is enclosed.

As a preferred example, the number of filter segments is two or more, and at least one filter segment is of a type different from other filter segments.

According to the present invention, there is provided the cigarette filter according to claim 1, a cigarette rod connected to the cigarette filter via a tip paper, and a vent hole formed in the tip paper. Provide a filter cigarette.

According to the present invention, the cigarette filter according to claim 1, a cigarette rod connected to the cigarette filter via chip paper, and a vent hole formed in the chip paper, the vent hole includes: Provided is a filter cigarette that is located upstream in the suction direction from the position of the additive.
The present invention also provides a filter cigarette comprising the cigarette filter according to claim 3, wherein the at least one filter segment is a charcoal filter segment.

Furthermore, in this invention, it is a manufacturing method which manufactures the continuous body of the cigarette filter of Claim 1, Comprising: It conveys these filter segments mounted on the conveyance belt at intervals, and is conveying The additive is disposed between the filter segments, the filter segment is pushed out from the conveyor belt on a mounting table arranged continuously with the conveyor belt, and the filter segment that follows on the mounting table, A segment continuous body in which the additive is embedded in a boundary region between the filter segments is formed, and the continuous body is formed by wrapping the segment continuous body with the molding paper. A method for producing the continuum is provided.

According to the present invention, an additive used as a fragrance or an adsorbent (for example, a capsule in which a fragrance is enclosed in the case of an additive used as a fragrance) is embedded in a boundary region between filter segments. . When embedding the additive, the filter segment is not specially processed. In addition, since the additive is embedded in the boundary region between the plurality of filter segments, it is easy to align the position where the additive is embedded. Also, by using a plurality of filter segments, the types of adjacent filter segments can be made different, and the filter specifications can be easily changed. If the filter segments are brought into close contact with each other, the entire additive is embedded in the filter fiber. For this reason, since the space | gap for embedding a capsule between filter segments becomes unnecessary, it is preferable. That is, all of the cigarette filters can be used as a filtering material.

Further, according to the present invention, the additive is a capsule in which a fragrance or an adsorbent is enclosed. For example, when a capsule of a type in which a fragrance or an adsorbent is generated by crushing is used, the shape of the capsule returns to its original shape even if the filter is crushed at the same time as the capsule is crushed due to the restoring property of the filter fiber. Therefore, the handleability is improved.

Further, according to the present invention, different filter segments can be used by using so-called dual filters, triple filters, etc., so that the filter specification can be easily changed.
Moreover, according to this invention, the filter cigarette which show | plays the effect as mentioned above can be obtained.

Also, according to the present invention, the amount of tar, nicotine, etc. can be controlled by providing a vent hole. In addition, the vent hole provided in the chip paper connecting the cigarette filter and the tobacco rod is formed in the upstream side in the suction direction from the position where the additive (for example, the capsule) is embedded, so that it is carried in the capsule. It is preferable because the perfumes can be sufficiently tasted.

Further, according to the present invention, even when at least one filter segment is a fragrance-adsorbing charcoal filter segment, the fragrance is encapsulated and is not adsorbed by charcoal (activated carbon). Therefore, even if a fragrance | flavor adsorptive filter segment is used, the fragrance which a fragrance | flavor has can fully be tasted. In addition, it is preferable to position the charcoal filter segment upstream of the additive (capsule) in the suction direction because it is possible to reliably prevent the perfume from being adsorbed.

Further, according to the present invention, the filter segments are sequentially pushed out on the mounting table, so that the plurality of filter segments are in a so-called crushing state. At this time, the additive can be embedded in the boundary region between the filter segments. Therefore, the additive can be easily embedded between the filter segments with a simple structure, and a continuous body of cigarette filters in which the additive is embedded can be formed.

As shown in FIG. 1, a cigarette filter (filter module) 1 according to the present invention includes a plurality (two in the figure) of filter segments 2, a forming paper 3 around which the filter segments 2 are wound (wrapped), and a filter segment. 2 and a capsule (additive) 4 located between the two. For example, when the additive is a capsule enclosing a liquid or the like, a molding paper 3 having a function of preventing the liquid or the like from exuding is used. For example, oil resistant paper. The filter segment 2 is formed by wrapping filter fibers (tow) 5 in a cylindrical shape with a web 6. Various types of filter segments 2 can be used. For example, a charcoal filter or a plane filter. In FIG. 1, a charcoal filter 5a is used on the upstream side in the suction direction of the filter cigarette, and a plain filter 5b is used on the downstream side. Since the example of FIG. 1 uses two filter segments 2, a so-called dual filter is shown. As described above, since a plurality of types of filter segments 2 are used, the types of adjacent filter segments 2 can be made different, and the filter specifications can be easily changed. Of course, as shown in FIG. 2, the same type of filter segments 2 may be arranged (in the figure, the plane filter 5b is arranged). Any number of filter segments 2 may be arranged as long as they are plural. The capsule 4 may be arranged between the filter segments 2 or may be arranged only between arbitrary filter segments 2. Also, two or more capsules 4 may be arranged in the boundary area between the same filter segments 2. In addition, when there are a plurality of filter segments 2, it is preferable to dispose the capsule downstream in the suction direction from the fragrance-adsorbing filter segment. The filter segment 2 may or may not have the web 6.

The capsule 4 is filled with a fragrance (solid, liquid or powder) such as a menthol carrier or an ester carrier. The capsule 4 is made of gelatin or pullulan. When formed with gelatin, the encapsulated fragrance is scattered by crushing the capsule 4. When it is formed of pullulan (or glucan), the capsule film is broken by the moisture of the tobacco 10 without crushing the capsule 4, and the encapsulated fragrance is scattered. The capsule 4 may contain not only the above-described fragrance (fragrance) but also an adsorbent such as activated carbon, hydrotalcite, zeolite, or silica. On the other hand, solids such as pellets may be used as additives instead of capsules having a disintegrating property. That is, in order to exert the action of the flavoring agent and the adsorbent, either a capsule in which these are encapsulated or a solid formed by itself may be used. In other words, either a disintegrating material covered with a film such as a capsule or a non-disintegrating material such as a pellet (solid material) may be used. “Additives” is a general term for capsules and solids. In the following, the description will be continued by taking the crush type capsule 4 formed of gelatin as described above as an example.

The capsule 4 is disposed in a boundary region between adjacent filter segments 2 and the adjacent filter segments 2 are in close contact with each other with almost no gap. That is, the capsule 4 is embedded between the filter segments 2. Therefore, a gap for embedding the capsule 4 is not necessary. Further, even if the capsule 4 is crushed and the filter segment 2 is crushed at the same time, the shape of the filter fiber 5 is restored due to the restoring property of the filter fiber 5. For this reason, handleability improves.

Note that, as is apparent with reference to FIG. 3, some capsules 4 may be embedded by providing a slight gap without adjoining the adjacent filter segments 2. On the other hand, the shape of the capsule 4 is not limited to the spherical shape described above, but may be an elliptical cross section as shown in FIG. 4 or a rhombus cross section as shown in FIG. Further, the above-described features can be applied to a cigarette filter of a type that does not have the web 6 (see FIGS. 1 to 5) as shown in FIG. In FIG. 6, the example in which the web 6 is not provided in the example of FIG.

When using the charcoal filter 5a as shown in FIG. 1, it is preferable to dispose the charcoal filter 5a upstream from the capsule 4 in the cigarette suction direction. This is because, when the fragrance is menthol, if the charcoal filter is disposed on the downstream side, the menthol is adsorbed by the charcoal filter 5a. By arranging the charcoal filter 5 a on the upstream side of the capsule 4, the refreshing feeling of menthol can be fully enjoyed.

The filter cigarette 7 is formed by wrapping the above-described cigarette filter 1 and the tobacco rod 8 with the tip paper 9. The tobacco rod 8 is formed by wrapping a cut tobacco 10 in a cylindrical shape with a wrapping paper 11. The cut tobacco 10 is a mixture of burley leaves, sheet tobacco, and the like. The chip paper 9 is formed with a vent hole 12 penetrating the inner side and the outer side. The vent hole may or may not be provided. However, in the case of providing the vent hole, it is preferable that the vent hole 12 penetrates to the tip paper 9, the forming paper 3, and the web 6. The vent hole 12 is formed upstream of the capsule 4 in the suction direction of the filter cigarette 7. By providing the vent hole 12 at such a position, it is possible to fully enjoy the fragrance carried in the capsule 4. In addition, when smoking, the capsule 4 is first crushed by hand, and the fragrance | flavor in it is made to ooze out to the filter fiber 5. FIG.

As shown in FIG. 7, the manufacturing apparatus 13 includes a conveyor belt 14, a mounting table (bridge) 15, and a garnish belt 16. The conveyor belt 14 is a so-called belt conveyor. An upper conveyance belt 17 that rotates at the same speed is provided above the conveyance belt 14. The mounting table 15 is continuously arranged with the conveyor belt 14 and does not particularly have a drive mechanism. The surface of the mounting table 15 is formed on the same plane as the conveyance surface of the conveyance belt 14. Similarly, the garniture belt 16 having a conveying surface on the same plane as the mounting table 15 is located on the opposite side of the conveying belt 14 via the mounting table 15. The garniture belt 16 is provided with a molding bed and a tongue (not shown). When the garniture belt 16 is conveyed, the filter segment 2 is wrapped with molding paper to become a continuous body of a long cigarette filter.

In the method for producing a continuous cigarette filter according to the present invention, first, the filter segment 2 is placed on the conveyor belt 14 with an interval. During transport, the capsule 4 is dropped between adjacent filter segments 2. Various known devices can be used as the device for dropping the capsule 4. Note that the capsule 4 is not limited to being dropped, and any method may be used as long as it can be disposed between adjacent filter segments 2. In this state, the filter segments 2 and the capsules 4 are transported to the mounting table 15 by the transport belts 14 and 17. When transported to the mounting table 15, the filter segment 2 and the capsule 4 stop there. The filter segment 2 and the capsule 4 conveyed to the mounting table 15 are pushed out by the subsequent filter segment 2 and the capsule 4 on the conveyance belt 14. Therefore, the distance between the filter segments 2 is gradually reduced. Since the filter fiber 5 is soft, the capsule 4 moves on the mounting table 15 while being embedded between the filter segments 2. Eventually, the distance between the filter segments 2 becomes zero, forming a segment continuum 18. In this state, it moves onto the garniture belt 16 to form a continuous body of cigarette filters in which the capsules 4 are embedded.

Note that the conveyance speed of the garniture belt 16 is lower than the conveyance speed of the conveyance belt 14. Specifically, the speed is such that the distance between the filter segments 2 at the exit of the mounting table 15 becomes zero. By providing a speed difference between the garnish belt 16 and the conveyor belt 14, it is possible to reliably realize the close contact between adjacent filter segments 2 on the mounting table 15. Thus, the capsule 4 can be easily embedded between the filter segments 2 with a simple structure, and a continuous body of cigarette filters in which the capsule 4 is embedded can be formed. Moreover, it is possible to arrange | position the addition position of a capsule by such continuous operation. In order to make the burying position of the capsule 4 near the center of the filter segment 2, the position of the capsule 4 may be manipulated by blowing up with air at the moment when the capsule 4 is sandwiched between the filter segments 2.

As shown in FIG. 8, the end surfaces of the front and rear filter segments 2a in the transport direction (arrow F) may be inclined with respect to each other. Even if it does in this way, the area of end surfaces becomes equal and it mutually adheres. FIG. 8 shows a state of being conveyed on the conveyor belt 14. If it is conveyed to the mounting table 15 in this state and pushed by the subsequent filter segment, the interval between the filter segments 2a and 2b is gradually narrowed. At this time, as shown in FIG. 9, the spherical capsule 4 moves to the vicinity of the center of the filter segment 2 along the inclined end surfaces. And as shown in FIG. 10, it embeds in the center vicinity as it is. Thereby, the embedding position of the capsule 4 can be stabilized, and quality can be improved.
