Definitions

  • the present invention relates to a thinly rolled cigarette.
  • a thinly rolled cigarette for example, a cigarette called "Superslim", which has a diameter of 5.4 mm, is on the market.
  • a further thinner cigarette called “Microslim” is also known.
  • These thinly rolled cigarettes have a specific problem resulting from their thinness. Namely, thinly rolled cigarette is apt to have an increased draw resistance of the cigarette because of its thinness.
  • the cigarette draw resistance is correlated to the ease of smoking by a smoker, and a cigarette having an excessively high draw resistance is difficult to be smoked. It is generally said that the cigarette draw resistance is desired to be 80 to 150 mmH 2 O.
  • Patent Document 1 discloses a thinly rolled cigarette (diameter: 5 to 7 mm) having a tar amount of 1 mg or less and including a dual-segment filter. Actually, the present inventors analyzed some commercial available thinly rolled cigarettes, but could not find a cigarette having a cigarette draw resistance of 150 mmH 2 O or less and a tar value of 8 mg or more in mainstream smoke.
  • the multi-segment filter when a multi-segment filter is employed in a cigarette, the multi-segment filter has a higher filter draw resistance as compared to a plain filter because the multi-segment filter has a plurality of segments. That is, the multi-segment filter has a larger amount of paper surrounding a filter material as compared to the plain filter, and therefore the filter material should have a smaller diameter.
  • the filter draw resistance greatly increases.
  • a flavor releasing material-containing filter and a multi-segment filter are apt to have an increased filter draw resistance. Therefore, in a thinly rolled cigarette including such a filter, it is further difficult to achieve both a desired low cigarette draw resistance and a high tar amount.
  • an object of the present invention is to provide a thinly rolled cigarette comprising a flavor releasing material-containing filter, the thinly rolled cigarette having a low cigarette draw resistance and a high tar amount.
  • an object of the present invention is to provide a thinly rolled cigarette comprising a flavor releasing material-containing multi-segment filter, the thinly rolled cigarette having a low cigarette draw resistance and a high tar amount.
  • the present inventors have found that even when a flavor releasing material is added to a filter of a thinly rolled cigarette, both a desired low cigarette draw resistance and a high tar amount can be achieved by using as a filter material an acetate tow having a filament denier of 10-13 g/9000 m and a total denier of less than 15000 g/9000 m, leading to completion of the present invention.
  • a cigarette according to claim 1 comprising:
  • the filter is a multi-segment filter including a plurality of filter segments, and at least one of the filter segments contains an acetate tow having a filament denier of 10-13 g/9000 m and a total denier of less than 15000 g/9000 m.
  • the present invention provides a thinly rolled cigarette comprising a flavor releasing material-containing filter, the thinly rolled cigarette having a desired low cigarette draw resistance and a high tar amount.
  • the present invention provides a thinly rolled cigarette comprising a flavor releasing material-containing multi-segment filter, the thinly rolled cigarette having a desired low cigarette draw resistance and a high tar amount.
  • FIG. 1 shows one example of a thinly rolled cigarette.
  • an end of a tobacco rod 10 is cut off so that the inside of the tobacco rod 10 can be seen.
  • the cigarette according to the present invention has a diameter of 3.0 to 6.0 mm, and is thinly rolled.
  • the cigarette according to the present invention has a diameter of, for example, 4.5 mm or 5.4 mm.
  • the cigarette according to the present invention has a structure similar to that of a usual filter-tipped cigarette except that the diameter is small. That is, the cigarette according to the present invention includes the tobacco rod 10 and a filter 20, and the tobacco rod 10 and the filter 20 are connected to each other by a tipping paper 30.
  • the total length of the cigarette according to the present invention may be, for example, 80 to 100 mm.
  • the tobacco rod 10 is formed of a tobacco filler 11 and a cigarette paper 12 wrapped around the periphery of the tobacco filler 11, as in a usual cigarette.
  • the tobacco rod 10 has a diameter of 3.0 to 6.0 mm and may have a length of, for example, 50 to 75 mm.
  • the cigarette paper 12 may have a thickness of 10 to 100 ⁇ m, and a paper having air permeability is generally used as the cigarette paper 12.
  • the filter 20 is disposed at an end of the tobacco rod 10, and is formed of a filter member 21 and a filter wrapping paper 22 wrapped around the periphery of the filter member 21.
  • the filter 20 has a diameter almost equal to that of the tobacco rod 10, and may have a length of, for example, 25 to 30 mm.
  • the filter member 21 shown in FIG. 1 has a single filter structure, so called plain filter structure.
  • the filter wrapping paper 22 which is integrally wrapped around the periphery of the filter member 21 may have a thickness of 10 to 100 ⁇ m, and may or may not have air permeability.
  • the filter wrapping paper 22 has perforations 23 at the same positions as those of the perforations 31 of the tipping paper 30 so that the perforations 23 communicate with the perforations 31.
  • the filter member 21 is constituted of an acetate tow having a filament denier of 10-13 g/9000 m and a total denier of less than 15000 g/9000 m.

  • the flavor releasing material 24 contains a flavor component and a component for suppressing volatilization of the flavor component.
  • the flavor releasing material 24 may be in the form of a capsule containing a flavor component.
  • Such a flavor releasing material in the form of a capsule has a diameter size of several ten micrometers, and a large number of flavor releasing materials are dispersively contained in the filter member 21 (see FIG. 1 ) (see, for example, WO 2009/157240 ).
  • the flavor releasing material in the form of a capsule has a diameter size of several millimeters, and one to several flavor releasing materials may be embedded in the filter member 21 (see, for example, WO 2011/024068 ), or may be contained in a cavity formed between two filter segments spaced apart from each other (see, for example, WO 2006/117697 ).
  • the flavor releasing material 24 may be in the form of a thread (string) impregnated with a flavor component, and it is contained so as to pass through the center of the filter (see, for example, Jpn. Pat. Publication No. 63-38187 ).
  • the flavor component contained in the flavor releasing material 24 may be any flavor component used in a cigarette, such as menthol.
  • the flavor releasing material 24 can be added in an amount of 35 mg or more per cigarette, for example 35 to 235 mg per cigarette.
  • the cigarette according to the present invention may further include an adsorbent such as activated carbon in the filter member 21.
  • the tipping paper 30 is bonded by an adhesive so as to cover the whole of the filter wrapping paper 22 and a part of the cigarette paper 12.
  • a portion of the tipping paper 30 which covers the filter wrapping paper 22, is called a "tipping paper of a filter portion".
  • the tipping paper 30 may have a length (width) of 30 to 37 mm in an axis direction of the tobacco rod, and a thickness of 10 to 100 ⁇ m.
  • the tipping paper has perforations 31 for letting air flow into the inside of the cigarette (filter member 21) from the outside during puffing.
  • the perforations for air permeation have a function of letting air flow into the inside of the cigarette therefrom during puffing, and as a result, the air inflow quantity from the cigarette top is decreased to reduce the cigarette draw resistance.
  • the perforations for air permeation are provided in a line along a circumferential direction of the cigarette in FIG. 1 , but may be provided in a plurality of lines along the circumferential direction of the cigarette, or a large number of perforations may be irregularly provided.
  • the perforations 31 are formed so as to pierce the tipping paper of the filter portion and the filter wrapping paper 22.
  • a total air quantity (Q) sucked out from a mouthpiece of the cigarette consists of an air quantity (Qt) flowing in from the cigarette top, an air quantity (Qp) flowing in by passing through the cigarette paper 12, and an air quantity (Qf) flowing in from perforations 31 of the tipping paper 30.
  • a ratio (Vt) of the air quantity (Qt) flowing in from the cigarette top is represented by 100 ⁇ Qt/Q (%); a ratio (Vp) of the air quantity (Qp) flowing in by passing through the cigarette paper is represented by 100 ⁇ Qp/Q (%); and a ratio (Vf) of the air quantity (Qf) flowing in from the perforations of the tipping paper is represented by 100 ⁇ Qf/Q (%).
  • the ratios of the air quantities (Vt, Vp and Vf) can be obtained by measuring the air quantities under standard smoking conditions in accordance with the ISO standard method using a cigarette quality measurement device (ISO 9512).
  • the target tar amount in the cigarette according to the present invention is 8 mg or more.
  • the ratio (Vf) of the air quantity flowing in from the perforations of the tipping paper to the total air quantity (Q) may be appropriately set for the purpose of achieving the target tar amount, and may be set to, for example, 10 to 60%, preferably 20 to 50%.
  • the ratio (Vt) of the air quantity flowing in from the cigarette top to the total air quantity (Q) is generally 28 to 90%
  • the ratio (Vp) of the air quantity flowing in by passing through the cigarette paper to the total air quantity (Q) is generally 0 to 12%.
  • Vf value can be obtained by adjusting the size and number of perforations of the tipping paper by changing the power and pulse length of a laser perforator mounted in a cigarette production machine.
  • the filter wrapping paper 22 has perforations 23 at the same positions as those of the perforations 31 of the tipping paper 30 so that the perforations 23 communicate with the perforations 31, as described above. Therefore, the perforations can be provided by making holes using the laser perforator so as to pierce not only the tipping paper but also the filter wrapping paper. Therefore, the air permeability of the filter wrapping paper does not matter.
  • a paper having an air permeability of 5 to 100 CU, preferably 60 CU or less is used as a raw material of the cigarette paper 12.
  • the cigarette paper 12 may contain a combustion regulator such as citrate in an amount of 1.0% by mass or less based on the mass of the cigarette paper.
