A mechanical method of molding an opening, or an electrical method by corona discharge.

The filter body 22 can be formed from a variety of filler materials. In the present embodiment, the filter body 22 is made of, for example, a filler of cellulose-based synthetic fibers such as cellulose acetate, but the filler is not limited thereto. For filling materials, for example, plant fibers such as cotton, hemp, manila hemp, coconut, and rush; animal fibers such as wool and cashmere wool; cellulose-based regenerated fibers such as enamel; nylon, polyester fiber, acrylic, polyethylene, and the like. Synthetic fibers such as polypropylene or a combination thereof. The constituent elements of the filter portion may be a carbon-containing carbon filter or a filter containing particles other than carbon, in addition to the above-mentioned filler containing cellulose acetate fibers. Further, the filter portion may have a multi-segment structure in which two or more different types of segments are connected in the axial direction. At this time, each of the segments is wound around the wrapper 23 to be fixed to the filter portion 13. For each of the sections, the respective filling materials may be wound by the winding material of the section, or the 15th drawing of Japanese Patent No. 4262247 may be used. No-wrapped filter.

Further, at least one of a plasticizer and a binder may be added to the filter body 22 of the filter portion 13 in order to make the filter portion 13 have a desired hardness. The type of plasticizer used is not limited. For example, as a plasticizer, triethyl citrate, acetaminophen/triethyl citrate, acetyl citrate/tributyl citrate, dibutyl tartrate, ethyl phthalic acid/ethanol Ethyl acetate, methyl phthalic acid / ethyl glycolate, triacetin, triethyl phosphate, triphenyl phosphate, tripropionin or a combination thereof. The type of binder used is not limited. For example, the binder may be HMC, HPMC, PVA, PVAc, PEG or a combination thereof. Plasticizers and binders may also be used, as appropriate.

Further, the filter body 22 may contain a flavor such as menthol. The flavor addition method of the flavoring agent is not particularly limited, and for example, the strip-like substance to which the flavor agent is adsorbed may be disposed in the filter body, or the filler of the filter portion 13 may contain a flavoring agent, or the capsule may be A method in which a material to which a flavoring agent is fixed is disposed in a filter portion. The type and material of the take-up material 23 (winding paper) used in the filter body 22 of the filter portion are not limited. As the take-up material 23, a take-up paper used for a general cigarette filter can be used, and it can be a gas-permeable take-up paper or a non-breathable take-up paper. Since the gas permeability of the wound material 23 affects the amount of dilution air introduced from the gap between the first covering portion 15 and the second covering portion 16, it is possible to visually obtain the first covering portion 15 and the second covering portion 16 as desired. The gas permeability of the appropriate coiled material 23 is selected by the amount of dilution air introduced into the gap. The take-up paper used for a general product has a basis weight of 20 to 100 [g/m ² ], a thickness of 30 to 110 [μm], and a gas permeability of 0 to 30,000 [Coresta unit]. As the material of the coiled material 23, generally, a paper made of vegetable fibers can be used, but a non-woven fabric or a polymer system using a chemical fiber (polypropylene, polyethylene, nylon, etc.) may be used. A film of (cellulose, cellulose acetate, polypropylene, polyethylene, nylon, polylactic acid, etc.) or a metal foil such as aluminum foil.

The filter paper (the first covering portion 15 and the second covering portion 16) used in a general product is a paper having a basis weight of 35 to 56 [g/m ² ] and a thickness of 35 to 45 [μm]. The surface which can be used for the printing of a brand name or the like can be easily smoothed, and a filler such as titanium oxide or calcium carbonate can be blended so as not to penetrate and the filter portion can be seen to improve the opacity. The material of the filter paper (the first covering portion 15 and the second covering portion 16) is not limited. In the case of the filter paper, paper made of vegetable fibers is generally used, but a non-woven fabric or a polymer system (cellulose) using a chemical fiber (polypropylene, polyethylene, nylon, etc.) may also be used. For the film of cellulose acetate, polypropylene, polyethylene, nylon, polylactic acid, etc., a metal foil such as aluminum foil can also be used.

The gap between the first covering portion 15 and the second covering portion 16 is adjusted to an extremely small size. Therefore, the amount of air introduced into the filter portion 13 from the gap is extremely small. Further, in the cigarette 11, the wrapper 23 which is non-breathable or has gas permeability but relatively low gas permeability can be used. Thereby, even if a small amount of external air is introduced into the filter portion 13 from the gap, the mainstream smoke is not diluted to a required level or more by the outside air. On the other hand, on the contrary, by applying the above gap and using the relatively high gas permeable material 23, the outside air (air) can be actively guided into the filter portion 13 to dilute the mainstream smoke.

The action of the cigarette 11 of the present embodiment will be described with reference to Fig. 4, Fig. 5 and the like. In the present embodiment, when the smoker wants to change the concentration of the smoke of the cigarette 11, the mouth side portion 13B is rotated with respect to the tobacco portion side portion 13A of the filter portion 13 (the second cover portion 15 is made second) The cover portion 16 is rotated, whereby the concentration of the smoke can be made thicker or lighter.

As shown in Fig. 4, in the state in which the cigarette 11 is taken out from the package, for example, the first portion 17A of the first opening portion 17 is disposed in the second portion 17B with respect to the first opening portion 17. The circumferential direction R of the second covering portion 16 is at the first position P1 at which the position is displaced. At the first position P1, the third portion 18A of the second opening portion 18 is displaced from the fourth portion 18B of the second opening portion 18 in the circumferential direction R of the second covering portion 16. In this state, the smoker can enjoy the rich aroma caused by the concentrated smoke by igniting the front end of the tobacco portion 12 and sucking it from the suction port 24.

The smoker moves the suction port side portion 13B and the second covering portion 16 with respect to the tobacco portion side portion 13A of the filter portion 13, and can move from the first position P1 to the first portion of the first opening portion 17 17A is the second position P2 that is integrated with the second portion 17B of the first opening portion 17. At the second position P2, the third portion 18A of the second opening portion 18 is integrated with the fourth portion 18B of the second opening portion 18. In the present embodiment, as shown in FIG. 4, the suction side portion 13B and the second covering portion 16 are rotated by about 150 in the clockwise direction (the arrow direction in FIG. 4) viewed from the suction opening side 24, for example. It can be moved from the first position P1 shown in Fig. 4 to the second position P2 shown in Fig. 5. In this state, as indicated by the arrow in Fig. 5, The plurality of first opening portions 17 and the plurality of second opening portions 18 actively introduce air into the filter portion 13. Thereby, the smoke flowing through the filter portion 13 can be diluted, and the smoker can enjoy the refreshing scent (sweet taste) caused by the relatively low concentration of smoke.

As described above, in the state of the second position P2, the ratio of the air introduced from the first opening portion 17 and the second opening portion 18 in the mainstream smoke can be, for example, a high value of 60 to 80%. Thus, if high gas permeability can be achieved, it is easy to make the mainstream smoke low in tar. Further, since the smoker can rotate the mouth-portion side portion 13B by a large angle of about 150° from the first position P1 to the second position P2, it is possible to achieve a smoker's interest as a hobby. Construction. Moreover, it is preferable to provide an index (indicator) indicating the rotation direction of the suction port side portion 13B and the second covering portion 16 in the first covering portion 15 or the second covering portion 16.

On the other hand, the smoker can ignite the front end of the tobacco portion 12 in a state where it is located at the second position P2 in advance, thereby enjoying a refreshing savory taste from the beginning. Moreover, the smoker can view the mouth side portion 13B toward the side of the suction port 24 with respect to the tobacco portion side portion 13A of the filter portion 13 when the smoker desires to taste the smoke with a relatively high concentration. The clockwise rotation is, for example, 150°, and returns to the first position P1 from the second position P2. In this way, smokers can also taste the rich flavor of smoke.

In addition, the smoker can rotate the suction port side portion 13B and the second cover portion 16 by a certain angle from the state of the second position P2, and can be plural to the second portion 17B of the plurality of first opening portions 17. The first portion 17A of the first opening portion 17 is only partially overlapped. In this In the state, the third portion 18A of the plurality of second opening portions 18 of the fourth portion 18B of the plurality of second opening portions 18 is partially overlapped. Thereby, the air permeability can be adjusted to a degree of air permeability which is located between the first position P1 and the second position P2.

Next, the manufacturing steps of the cigarette 11 of the present embodiment will be described. First, the tobacco portion 12 (roll) and the filter portion 13 having a length of 2 are manufactured by a general method. Then, the filter portion 13 having a length of 2 pieces is inserted between the two tobacco portions 12. In the filter portion 13, a disk-shaped cutter or the like is used in advance, and a rotating portion 21 is formed inside the notch portion 25. Then, the covering portion (filter paper) arranged in the order of the first covering portion 15, the second covering portion 16, and the first covering portion 15 is rolled up the tobacco portion 12 and the filter portion 13 at a time, thereby forming a connection tobacco portion. 12 and the rod of the filter portion 13. At this time, the second covering portion 16 located at the center has a length corresponding to the cigarettes 11 of the two portions. The two first covering portions 15 and the second covering portion 16 are coated with a bonding material before winding.

Irradiated. A plurality of first opening portions 17 (both the first portion 17A and the second portion 17B) and the second opening portion 18 (the third portion 18A and the plurality of first opening portions 17) are formed in the second covering portion 16 by the pulsed laser light. Part 4, Part 18B). At this time, in the cigarette 11, the positional relationship between the first opening portion 17 and the second opening portion 18 is at the second position P2, the first portion 17A is integrated with respect to the second portion 17B, and the third portion 18A is opposed. In Part 4, 18B is integrated. Then, the filter portion 13 and the second covering portion 16 (filter paper) are cut by a cutter at a central position of the filter portion 13 having a length of two to produce one cigarette 11. Further, the cigarette 11 is rotated from the second position P2 until the first portion 17A and the second portion 17B are displaced in the circumferential direction R (the third portion 18A and the fourth portion 18B are displaced in the circumferential direction R). The first position P1 is packed in the state. The rotation operation from the second position P2 to the first position P1 can cut the filter portion 13 by the cutter at the center position of the filter portion 13 having the length of two in the cigarette manufacturing step. And the step of manufacturing the one cigarette 11 by the second covering portion 16 (filter paper), and then using the rotating mechanism provided in the step after the step; the manual operation may be performed manually; or the packaging device may be used. Part of the rotating mechanism is automated.

Further, the method of manufacturing the plurality of first opening portions 17 and the plurality of second opening portions 18 is not limited to the above. For example, after the normal cigarette 11 is manufactured, a plurality of first opening portions 17 and a plurality of second opening portions 18 may be provided by CO ₂ laser.
