Abstract

PROBLEM TO BE SOLVED: To provide a cigarette filter which can change a filter type of an upstream side and a downstream side on the boundary of a capsule (an additive) while obtaining excellent restorability and stably adding the capsule without bleeding at the time of crushing the capsule and requiring enlargement of the filter per se, and to provide a filter cigarette using the cigarette filter and a manufacturing method of continuous cigarette filters.SOLUTION: The cigarette filter includes: a plurality of filter segments 2 which are arranged linearly in one direction and mutually cohesive; an additive 4 (a capsule) which is buried in a boundary region among the filter segments 2 and used as a fragrance imparting agent or an adsorbent; and a forming paper 3 which is wrapped around the plurality of filter segments 2 to connect these filter segments.

Description

  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 producing a cigarette filter continuous body.

  For example, a filter rod in which a capsule in which a fragrance is sealed in a filter is added 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 describes a cigarette filter in which a gap is provided in a filter and 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, if the fragrance | flavor in a capsule is a liquid, possibility of oozing out 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 takes time and labor to provide a recess in the filter in advance. 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 void does not have a filtration function, the performance as a cigarette filter cannot be sufficiently exhibited.

  According to invention of Claim 1, the additive used as a fragrance | flavor or an adsorbent (For example, in the case of the additive used as a fragrance | flavor, the capsule in which the fragrance | flavor is enclosed) is in the boundary area between filter segments. Buried. When embedding, no special processing is required for the filter segment. Moreover, since the additive is embedded in the boundary region between the plurality of filter segments, it is easy to align the position of the additive. 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 capsule embedding becomes unnecessary, it is preferable. That is, since the capsule is buried, no gap is required, and the entire cigarette filter can be used as a filtering material.

  According to the invention of claim 2, the additive is a capsule in which a fragrance or an adsorbent is enclosed. For example, in the case of a type in which a fragrance or an adsorbent is generated by crushing the capsule, restoration of the filter fiber Depending on the nature, even if the capsule is crushed and the filter is crushed, its shape returns. Therefore, the handleability is improved.

FIG. 1 is a schematic sectional view of a filter cigarette using a cigarette filter according to the present invention. FIG. 2 is a schematic sectional view of a filter cigarette using another cigarette filter according to the present invention.
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. And a capsule 4 located between the two. For example, when the additive is a capsule such as a liquid, the molding paper 3 has a function of preventing the liquid or the like from exuding. For example, oil resistant paper or the like is used. 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, the charcoal filter 5a is used on the upstream side in the suction direction of the filter cigarette, and the plane filter 5b is used on the downstream side. This is a so-called dual filter. 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 capsules 4 may be disposed between the filter segments 2 or may be disposed only at arbitrary positions. Also, two or more capsules 4 may be arranged in the boundary area between the same filter segments 2. When there are a plurality of filter segments 2, it is preferable that the capsule is located downstream in the suction direction from the fragrance-adsorbing filter segment. The filter segment 2 may or may not have the web 6.

  In the capsule 4, a fragrance (solid, liquid, powder, etc.) such as a menthol carrier or an ester carrier is enclosed. The capsule 4 is made of gelatin or pullulan. When formed with gelatin, the fragrance inside is scattered by crushing the capsule 4. When formed with pullulan (or glucan), the capsule film is broken by the moisture derived from the tobacco 10 without crushing the capsule 4, and the fragrance inside is scattered. In addition, the contents of the capsule may enclose 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 instead of capsules that disintegrate. That is, in order to exert the action of the flavoring agent and the adsorbent, either a capsule encapsulating these or a solid material 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. Although these capsules and solids are collectively referred to as additives, the description will be continued below by taking as an example the crushing type capsule 4 formed of gelatin as used above.

  The capsule 4 is disposed in a boundary region between adjacent filter segments 2 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 in the filter segment becomes unnecessary. Further, due to the restoring property of the filter fiber 5, even if the capsule 4 is crushed and the filter segment 2 is crushed at the same time, the shape is restored. For this reason, handleability improves.

  In addition, as shown in FIG. 3, the adjacent filter segment 2 does not need to contact | adhere. FIG. 3 shows the capsule 4 partially embedded. 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 according to the present invention 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 the charcoal filter 5a is used as shown in FIG. 1, it is preferable that the charcoal filter 5a is positioned upstream of 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 placing the charcoal filter 5a on the upstream side of the capsule 4, it is possible to fully enjoy the refreshing feeling of menthol.

  The filter cigarette 7 is formed by wrapping the 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. 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.

FIG. 7 is a schematic view of a manufacturing apparatus used in the method for manufacturing a continuous cigarette filter according to the present invention.
As illustrated, the manufacturing apparatus 13 includes a conveyance 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 does not particularly have a drive mechanism. The surface of the mounting table 15 is formed flush with the conveyance surface of the conveyance belt 14. Similarly, the garniture belt 16 having the same conveying surface 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), and the filter segment 2 is wrapped (wrapped) with molding paper when the garnish belt 16 is conveyed. It becomes.

  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 succeeding filter segment 2 and capsule 4 on the conveyor belt 14 push out the filter segment 2 and capsule 4 conveyed to the mounting table 15. Accordingly, 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.

  The transport speed of the garniture belt 16 is lower than the transport speed of the transport belt 14 and has a speed difference such that the distance between the filter segments 2 at the exit of the mounting table 15 becomes zero. By providing this speed difference, it is possible to reliably achieve 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 such as blowing up with air at the moment when the capsule 4 is sandwiched between the filter segments 2.

8 to 10 are schematic views sequentially showing the close contact of the filter segments when the method for producing another continuous cigarette filter of the present invention is used.
As illustrated, the end face of the front filter segment 2a in the transport direction (arrow F) is formed in a taper shape, and the end face of the rear filter segment 2b is formed in a reverse taper shape. Since both end faces are formed in a symmetrical taper shape, the end faces have the same area and are in close contact. FIG. 8 shows a state where the paper is being transported on the transport 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 taper surface of each other. 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.
