DETAILED DESCRIPTION Embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily practice the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. The drawings and description are to be regarded as illustrative in nature and not restrictive. Like reference numerals designate like elements throughout the specification. In addition, in the case of well-known technology, a detailed description thereof will be omitted.

Cigarette filter according to an embodiment of the present invention is applied to a double ventilated system (double ventilated system). Accordingly, by providing multiple flow passages of air flowing into the cigarette from the outside, the smoke component can be efficiently removed through diffusion, which is an important element of the mechanism for removing the smoke component from the filter. In addition, by appropriately adjusting the amount of air introduced into the cigarette from the outside, it is possible to enhance the amount of smoke transfer during smoking and to maintain a rich taste.

1 and 2, a cigarette 1 includes a cigarette column portion 10 that is burned by a fire and a cigarette filter portion 20 that filters cigarette smoke. It includes. Tobacco grass 10 may include a tobacco grass 11 that is processed in a variety of ways. Tobacco grass 10 may be surrounded by a cigarette paper 19, the cigarette filter 20 may be surrounded by a cigarette filter wrap (29). Tobacco grass 10 and the cigarette filter 20 may be connected by a tipping paper (tipping paper 30).

The tobacco filter unit 20 may include a filter unit 21, and the filter unit 21 may include fibrous or filamentous acetate tow. In addition, the tobacco filter unit 20 may include a flavor material. The flavor material may be contained in the flavor capsule, and the flavor material may be surrounded by the polymer material. In addition, the flavor material may be distributed in the filter portion, or may be contained in the granule-shaped micro flavor capsule. When pressure is applied to the flavor capsule from the outside, the flavor capsule may be broken, and the flavor material may leak out of the flavor capsule into the filter part. In order to have tobacco have more than one taste and aroma, flavor capsules can be usefully used. One or more flavor capsules may be located.

In addition, the tobacco filter unit 20 may include an adsorbent such as activated carbon, a thread in which a flavor substance is immersed, and the like. For example, when the tobacco filter unit 20 is a double filter, each of the two filters may include a flavor capsule and an adsorbent.

2 and 5, the cigarette filter unit 20 is a mono filter including the filter unit 21. In addition, the cigarette filter unit 20 may be a multiple filter. For example, the tobacco filter unit 20 may be a double filter as shown in FIGS. 3 and 6. 3 and 6, the cigarette filter unit 20 includes two filter units 22 and 23. In addition, the cigarette filter unit 20 may be a triple filter, a quadruple filter, or the like. Furthermore, the multiple filter may be a recess filter including one or more space portions or cavity portions. In addition, the length of each sub-filter part included in the multiple filter can be appropriately adjusted. In addition, at least one filter unit in the multiple filter may include at least one of an adsorbent and a flavoring substance.

When the tobacco filter is a double filter, the suction resistance of the filler-directional filter portion may be greater than the suction resistance of the mouth-directional filter portion. Alternatively, the suction resistance of each corner filter unit may be less than or equal to the suction resistance of the bulb filter unit. In addition, the length of each corner filter portion may be smaller than the length of the bend filter portion.

The cigarette filter unit 20 having a dual ventilation system includes a filler-directional ventilated portion 25, a mouth-directional ventilated portion 26, and a connection portion 24. It may include. The keratinocyte vent 25 is a part of the tobacco filter 20 positioned in the direction of the tobacco leg 10. The bent vent part 26 is a part of the cigarette filter part 20 located in the direction in which the mouth and the cigarette filter part 20 contact when smoking. For example, the periphery vent 25 may include ventilated holes 27 in the form of a circular band, and may include one or more vent holes. In addition, the spherical vent 26 may include a circular band-shaped vent hole 28, and may include one or more rows of vent holes. In addition, the periphery vent 25 and the vent vent 26 may include various types of ventilated openings. The connection part 24 is located between the periphery vent part 25 and the old vent part 26, and is a part of the tobacco filter part 20 which connects the two. The connection part 24 does not include the ventilation hole.

As shown in FIG. 1, the periphery vent 25 may include one row of vent holes 27, and the spherical vent 26 may include one row of vent holes 28. Alternatively, as shown in FIG. 4, the periphery vent 25 may include two rows of vent holes 27a and 27b, and the vent vent 26 may include two rows of vent holes 28a and 28b. It may include. In addition, the number of rows of the ventilation holes 27 located in the periphery vent 25 and the number of rows of the ventilation holes 28 located in the old vent 26 may not be the same. For example, the periphery vent 25 may include two or three rows of holes, and the vent vent 26 may include one row of vent holes.

The ventilation holes 27 and 28 are in an off-line method of previously drilling holes in the tip paper 30 before connecting the tobacco leg 10 and the cigarette filter 20 with the tip paper 30. It can be formed as. Alternatively, the ventilation holes 27 and 28 may be formed in an on-line manner to drill holes in the tip paper 30 during the cigarette manufacturing process. The ventilation hole 27 located at the periphery vent 25 and the ventilation hole 28 located at the old vent 26 may be formed in the same manner, and may be formed in different ways.

The length of the connection part 24 may be about 5 mm or more, and may be smaller than the length of the tobacco filter part 20. Dual ventilation may occur when the length of the connection portion 24 is about 5 mm or more, and dual ventilation may not occur when the length of the connection portion 24 is less than about 5 mm. In addition, the vent opening of the bent vent may be located between the ends of the mouth portion of the cigarette at the center of the filter, and the vent opening of the herbaceous vent may be located between the tobacco leg at the center of the filter.

Compared to a cigarette filter comprising a conventional mono ventilated system, a cigarette filter comprising a double vented system can have an increased open suction resistance (UPD) while maintaining an air dilution rate. Here, the air dilution rate is a value representing the amount of air introduced into the cigarette from the outside, and the taste of the cigarette may decrease when the air dilution rate increases. Cigarette filters with a dual ventilation system maintain air dilution, so that a rich tobacco taste can be maintained. When the open suction resistance is lowered, laxness may occur during smoking.

Further, as the ratio of the air dilution rate of the periphery vent 25 to the air dilution rate of the vented vent 26 increases, the open suction resistance UPD may increase.

Low tar cigarettes, including the conventional single ventilation system, may have low open suction resistance and may cause rashes. However, when the dual ventilation system is applied to low-tar cigarettes, the open suction resistance may increase, and thus, the sucking phenomenon may not occur. For example, an open suction resistance (UPD) of a cigarette including a dual ventilation system may be 50 mmH ₂ O or more, and the higher the open suction resistance (UPD), the faster the phenomenon may occur. Furthermore, the open suction resistance (UPD) of the cigarette may be desirable when it is 70 mmH ₂ O or more, and more preferably when it is 80 mmH ₂ O or more.

The air dilution rate of the cigarette including the dual ventilation system may be adjusted based on the porosity of the periphery vent 25 and the vent vent 26. For example, as the porosity increases, the air dilution rate may increase.

The porosity of each corner vent 25 and the sphere vent 26 may be less than 10,000 CU, each may be the same or different.
