≪ First Embodiment >

Fig. 1 shows a cigarette having a capsule filter according to a first embodiment of the present invention. The cigarette has a cylindrical tobacco rod 1 in which a tobacco packing 12 is wrapped with a wrapping paper 14 and a cylindrical filter 2 is connected to the periphery of a connection portion between the tobacco rod 1 and the filter 2 And the tip paper 3 wound around the tip paper 3 is connected.

The filter 2 has a rod-side plug 24a (placed on the cigarette rod side) and a suction-side plug 24b (disposed on the filter side), which are disposed apart from each other in the lengthwise direction of the cigarette by interposing the hollow portion 22 therebetween A capsule 26 is attached to the hollow portion 22 and wrapping paper wound around the rod side plug 24a and the suction side plug 24b as an example of the outer wrapping paper 28a and 28b and a molded paper 29 in which the hollow portion 22 is left around the winding paper 28a and 28b as an example of the outer paper. A filter having a structure in which a hollow portion is formed between a plurality of filter plugs is referred to as " cavity filter " in this specification).

For example, the filter plug may have a single-stranded filament extending in a direction substantially parallel to the longitudinal direction of the cigarette such as cellulose having a diameter of 1.0 to 14.0 g / 9000 m (preferably 5.0 to 14.0 g / 9000 m, more preferably 5.0 to 6.0 g / A plurality of acetate fibers are collected, and triacetin, for example, as a plasticizer for a filter is added in an amount of 2 to 10% (preferably 3 to 6%) of a plasticizer by weight in relation to the weight of the fibers to give a total fineness of 17000 to 44000 g / 9000 m (preferably 17000 to 35000 g / 9000 m) and a ventilation resistance of 100 to 700 mm H ₂ O / 120 mm (preferably 260 to 680 mm H ₂ O / 120 mm). Paper having a basis weight of 15 to 60 g / m 2, a thickness of 20 to 150 탆, and a width of 14 to 27 mm, which is mainly made of plant pulp, may be bundled. Activated carbon or the like may be contained in the filter plug.

As the tip paper 3, paper having a basis weight of 20 to 60 g / m < 2 > and a thickness of 20 to 60 mu m made mainly of plant pulp can be used. As the winding paper 28a, 28b and the formed paper 29, paper of a basis weight of 20 to 100 g / m 2, a thickness of 20 to 150 m, and an air permeability of 0 to 30000 coresta unit (CU) made mainly of plant pulp can be used.

For example, the length of the cigarette rod (a in Fig. 1) is 53 to 67 mm, the length of the filter (b in Fig. 1) is 17 to 31 mm, the peripheral length of the tip paper is 14 to 26.1 mm, And the length of the plug on the suction side (d in FIG. 1) are each 5 mm or more, and the size of the capsule in the length direction of the cigarette is 1 to 8 mm.

In the present embodiment, the capsule 26 is broken in the peripheral filter 21 before the press-in rate into the rod-side plug 24a and the suction-side plug 24b from the outside in the radial direction of the filter plug reaches 0.5.

<Peripheral filter>

Here, the peripheral filter is defined as a filter at a position where pressure is applied when the user presses the filter with the finger to break the capsule as indicated by 21a and 21b in Fig. 1, The length from the rod-side end of the peripheral filter 21a to the suction end of 21b is often about 10 to 20 mm.

Normally, when the user presses the filter with his or her fingers to break the capsule, it is necessary to apply pressure only to the position of the capsule in the longitudinal direction of the cigarette and the position of the capsule (hereinafter referred to as &quot; capsule portion & But also the filter 21 (peripheral filter) existing around the capsule portion 23 and the longitudinal direction of the cigarette.

<Indentation rate>

As shown in Fig. 3, the indentation rate is set such that the distance between the position (e) where the filter plug 242a is press-fitted in the state where the filter plug is not under external pressure is C, the distance from the filter plug (CD) / C in the case where the distance of the portion e '

&Lt; Capsule ratio &

The ratio of the diameter "B" of the circular shape as viewed from the filter cross-sectional side 21 of the capsule 26 to the "diameter A of the filter plug 24" (hereinafter referred to as the "capsule ratio" B / A can be 0.55 B / A 0.80, preferably 0.55 B / A 0.75, more preferably 0.55 B / A 0.70, and the capsule strain is 1 / 2/3.

<Diameter>

Here, as shown in FIG. 4, in the case where the diameter of the capsule 26 varies in accordance with the position of a cross section, such as when the capsule 26 is spherical, the diameter B, which is the largest value, .

<Capsule strain>

As shown in Fig. 5, the capsule strain was changed to a state in which the capsule f is subjected to external pressure and the state immediately before the capsule f is destroyed by the distance f at which the capsule 266a is pressed in the state where the capsule is not under external pressure Is defined as (EF) / E when the distance of the portion f 'where the capsule 266b at the time when the capsule 266 is pressed is denoted by F. [

<Capsule>

The capsule 26 has a structure in which the capsule 262 surrounds the contents liquid 264 including a flavor, which is an example of the contents. For example, the capsule may have a circular or elliptical cross-sectional shape as viewed from the filter cross-section side 21, and a spherical or cylindrical body as shown in Fig. 2 may be used.

The film-forming material includes, for example, starch and a gelling agent. As the gelling agent, for example, gellan gum may be used. The film-forming material may also contain a gelling aid. As the gelling agent, for example, calcium chloride may be used. In the present invention, the film-forming material may also contain a plasticizer for capsules. As the plasticizer for capsules, glycerin and / or sorbitol may be used. The film-forming material may also contain a coloring agent (coloring agent).

The capsule strain can be adjusted by changing the composition and thickness of the film-forming material.

As the fragrance contained in the content liquid of the capsule, for example, menthol, plant essential oil and the like can be used. As the solvent of the perfume contained in the content liquid, for example, a medium chain fatty acid triglyceride (MCT) can be used. The content liquid may also contain other additives such as coloring matters, emulsifying agents and thickening agents.

In addition, the capsule may contain the contents of an individual such as a granular form.

<Capsule Manufacturing Method>

The fragrance capsule manufacturing method is preferable because, for example, by using a dropping method, fragrance capsules having a smooth coating can be produced. In this method, by using the double nozzle to simultaneously discharge the content liquid from the inner nozzle and the liquid coating material from the outer nozzle, the coating liquid can wrap the content liquid without seam.

The inventors of the present invention investigated whether or not the user feels that the capsule is hardly broken in the conventional cigarette when the user breaks the capsule placed inside the cavity filter 2 by pressing the filter with the finger.

As shown in Fig. 6, the present inventors measured the pressure detected when the filter plug 242 provided on the stage 61 was press-fitted into the rheometer 62 arranged radially outward, As shown in Fig. 7 in Fig. 1 to 4 correspond to the sample numbers described in Tables 1 and 2, respectively, which will be described later. Fig. 7 is a graph in which the vertical axis represents the repulsive force per unit area of the filter plug unit, and the abscissa represents the indentation rate. As the indentation rate increases, the repulsive force increases. The repulsive force per unit cross-sectional area is a value obtained by dividing the repulsive force by the cross-sectional area (mm 2), and the cross-section means a circular cross-section orthogonal to the longitudinal direction of the cylindrical filter.

That is, as described above, when a capsule is destroyed by a normal user, the surrounding filter is also pressed. Therefore, when the capsule is destroyed, the filter plug acts as a repulsive force as in the measurement result. The larger the size, the larger the size becomes.

It should also be noted that when the indentation rate is less than a specific value (0.5 in this measurement), the repulsive force increases linearly as the indentation rate increases (the first incremental rate) The repulsive force is increased in a quadratic curve (a second rate of increase greater than the first rate of increase). That is, when the indentation rate is larger than the specific value, the repulsive force is greatly increased and the tendency of increasing the repulsive force during the indentation is changed. These are considered to be one of the factors that the user feels that the capsule is hard to break.

The rheometer used in the measurement in Fig. 6 is a Sun RHEOMETER CR3000EX (available from Sunkagaku Kogyo Co., Ltd.), and conditions for forming the filter plug are shown in Tables 1 and 2. No. A sample other than 4 was made of cellulose acetate fiber and triacetin was used as a plasticizer.

The cavity width in the longitudinal direction of the cavity filter is 6.0 mm. When the cavity filter is press-fitted, the center position in the width direction of the rheometer is defined as the width of the cavity And press-fitting was performed in accordance with the direction center position. In addition, in any sample, the filter plug was formed by winding a filter plug with a 50 g / m 2 basis weight and a thickness of 52 탆, and the length of the filter plug was 27 mm.

In the cigarette having the capsule filter according to the present embodiment, the capsule can be destroyed when the pressing rate of the filter is not more than a specific value (0.5), so that the user can feel that the capsule tends to be broken more easily than before.

9A to 9D show a state in which when the cavity filter 82 provided on the pressure sensitive conductive elastomer sensor 81 is pushed in from the top by the rheometer 62 as shown in Fig. And the detected pressure distribution. 9A to 9D, the X direction shown by the Y axis and the Y axis indicated by the horizontal axis correspond to the X direction and the Y direction shown in Fig. 8 . The pressure is higher in the order of 1, 2, .... The rheometer used in the measurement in Fig. 9 is the same as that described above, and the sensor 81 is an Instormer (manufactured by Inaba Kogyo Co., Ltd.).

9A to 9D show pressure distributions in a time series from the start of the press-fitting in this order. In Figs. 9A and 9B, it is shown that the pressure has not yet reached the capsule, and only the pressure is generated by the filter plug. In Fig. 9C, it is shown that the pressure reaches the capsule, and a pressure is also generated in the capsule portion. In Fig. 9D, it is shown that the pressure in the capsule portion, which has occurred in Fig. 9C, is almost lost due to the destruction of the capsule.

It can be seen from Fig. 9C that the portion where the high pressure is detected is displaced from the center position of the hollow portion of the cavity filter in the minus direction in the Y direction. From this, it can be seen that the capsule moves in the hollow part in the process of pushing the capsule disposed in the hollow part through the filter plug and destroying it. It is thought that the movement of this capsule is one of the factors that the user feels that the capsule is not easily broken in the conventional cigarette.

When the present invention is applied to the cavity filter as in the present embodiment, the range of movement in the hollow portion of the capsule becomes small because the capsule ratio is 0.55 B / A &amp;le; 0.8, and the user can feel have.

When the capsule 26 and the molded paper 29 (peripheral members in the present embodiment) are in contact with each other, in the process of pressing and destroying the capsule 26 disposed in the hollow portion 22, The movement of the capsule 26 is suppressed by the frictional force between the forming papers 29. [ Therefore, the user may feel that the capsule is easy to break. In the case where the shaping paper 29 is not used, for example, a member existing radially outward of the hollow portion of a tip paper or the like becomes a peripheral member.

In the case of using the cavity filter, the capsule ratio is preferably 0.55 B / A? 0.75, more preferably 0.55 B / A? 0.70 from the viewpoint of production stability.

As the diameter of the filter becomes smaller, the capacity of the capsule becomes smaller and the flow rate of the smoker becomes larger due to the suction of the smoker, so that the amount of the capsule flavor tends to be insufficient. This problem is also alleviated because the capacity of the capsule relative to the diameter of the filter is increased by using a cigarette having a capsule filter having a capsule ratio of 0.55? B / A? 0.8.

When an object is depressed with a finger and a certain degree of depression of the finger by the pressure is large, the person feels a feeling of being "hard", leading to the impression that "it is difficult to break". Therefore, in the case of a cigarette with a small diameter of the filter, the size of the capsule becomes small, so that the force tends to concentrate at one point of the finger. Therefore, even though the same load is applied as a whole, the small capsule is hardly & I feel. Even with a small-diameter cigarette which is likely to feel "difficult to break", the concentration of force on the finger can be alleviated by using a cigarette having a capsule filter with a capsule ratio of 0.55? B / A? 0.8, and the feeling of " Can be reduced.

Accordingly, the present invention can be more suitably applied in response to the case where the outer peripheral length of the tip paper is reduced to 25 mm or less, 23 mm or less, 17 mm or less, or 15 mm or less.

&Lt; Second Embodiment >

Fig. 10 shows a cigarette having a capsule filter according to a second embodiment of the present invention.

In this cigarette, the filter portion is different from that of the first embodiment, and the same parts are denoted by the same reference numerals and the description is omitted.

The filter 4 of the second embodiment has a filter plug 44 and a rewinding paper 46 which is an example of an outer foil wound around the filter plug 44 and a capsule 48). (A filter having a structure in which capsules are embedded in the filter is referred to as &quot; buried filter &quot; in this specification).

As the capsule, the filter plug, the tip paper and the winding paper, the same materials as those described in the first embodiment can be used, and the same size as that described in the first embodiment can be used for each dimension of the cigarette.

The method of manufacturing the capsule is the same as the capsule described in the first embodiment, and a description thereof will be omitted here.

The capsule 48 is also broken in the peripheral filters 41a and 41b before the penetration rate into the filter plug 44 from the radially outer side of the filter plug reaches 0.5.

The capsule ratio B / A can be 0.55 B / A 0.75, preferably 0.55 B / A 0.70, and the capsule strain is 2/3 or less.

In the cigarette having the filter according to the second embodiment, since the capsule is present in the filter, when the user destroys the capsule, the peripheral filters 41a and 41b are also pressed, so that the filter acts as a repulsive force , The repulsive force value becomes larger as the indentation rate increases to destroy the capsule.

However, since the cigarette having the capsule filter according to the present embodiment can break the capsule when the indentation rate of the filter is not more than a specific value (0.5), the user can feel that the capsule tends to be broken more easily than before.

The application of the present invention is particularly effective since a cigarette having a conventional buried filter has a tendency to give a large "difficult to break" feeling due to the presence of the filter at the capsule portion 43.

Generally, in a cigarette having a buried filter, a cellulose acetate fiber or the like is agglomerated and formed into a rod shape to produce a filter plug, and the capsules are formed in the fibers when the fibers are agglomerated.

Therefore, in the cigarette having the filter according to the second embodiment thus prepared, the capsule ratio of 0.55? B / A? 0.75 causes the filter plug at the capsule position to be pressed harder than the conventional one, It is easy to transmit to the capsule, and the user can feel that the capsule is easy to break.

Considering the relationship between the ease of breaking the capsule and the ventilation resistance felt when the user sucks the cigarette, when the capsule ratio is 0.55? B / A? 0.70, the ventilation resistance can be adjusted while maintaining the ease of breaking the capsule When the ventilation resistance is too high, the suction becomes difficult, and when the ventilation resistance is too low, it is difficult to obtain a feeling of being sucked).

As described above, the present invention can be more suitably applied to the present invention as long as the outer peripheral length of the tip paper is reduced to 25 mm or less, 23 mm or less, 17 mm or less, or 15 mm or less.

<Countermeasures>

Fig. 11 shows a cigarette according to a third embodiment of the present invention. The present embodiment uses a cavity filter similar to that of the first embodiment, and the same parts as those of the first embodiment are denoted by the same reference numerals, and a description thereof will be omitted. The points different from those of the first embodiment are that the winding paper 26 is not used and that the infiltration preventing molding paper 52 for preventing infiltration of the capsule contents liquid as the forming paper is used.

Examples of the infiltration-preventive formed paper 52 include internal resin (water-resistant paper) having internal water resistance or internal oil (oil-resistant paper) having oil-resistance performance, or water- Paper coated with wax or the like having water resistance and / or oil resistance can be used. In the case of such formed paper, the air permeability may be almost zero.

The gap filling layer 56 is formed between the penetration preventing formed paper 52 and the filter plugs 54a and 54b and the gap between the penetration preventing formed paper 52 and the filter plugs 54a and 54b . As the gap filling layer, an adhesive such as glue or hot melt can be used. Further, in the case of using paper coated with wax or the like having water resistance and / or oil resistance, the wax can serve as a gap filling layer.

When the capsule ratio is 0.55 B / A, a relatively large amount of the content liquid can be accommodated. However, by adopting the same structure as that of the present embodiment, it is possible to reduce the possibility that the content liquid leaks to the outside when the content liquid comes out from the inside of the capsule have.

Of course, it is also possible to construct a flush-type filter using a take-up reel and a gap filling layer to prevent penetration of the contents of the capsule, as in the above-mentioned anti- The present invention is also useful when a user destroys a capsule other than a finger.

In addition, the respective constituent elements and condition setting in each of the embodiments of the present invention described above can be individually combined independently of each other, unless otherwise specified.
