Definitions
- the present invention relates to a low flame-spreading cigarette that is unlikely to cause flame spread from the kindling to the surroundings so as not to allow the ignited cigarette to cause fire by, for example, the carelessness of the smoker.
- Cigarettes have been proposed, including, for example, a cigarette having a cellulose paper band, which is 2 to 20 mm wide, formed on the cigarette paper to impart self-extinguishing property(see Japanese Patent Disclosure (Kokai) No. 63-85200), and a cigarette in which a band coated with a flame retardant substance is formed on the cigarette paper (see Japanese Patent Disclosure (Kokai) No. 7-300795), in order to prevent the spread of flame from the kindling to, for example, the floor, where the cigarette is dropped onto, for example, the floor by the carelessness of the smoker. Further, a cigarette paper having a nonflammable substance pasted thereto is also known.
- a cigarette has been proposed, in which shredded tobacco are wrapped with a cigarette paper having a small amount of loading material used an inner paper and with an ordinary cigarette paper used as an outer paper (see Japanese Patent No. 2,572,488). Also, as a cigarette with a low sidestream smoke, a cigarette has been proposed, in which a smoking material rod having a loading density of 100 to 260 mg/cm 3 is wrapped by a wrapping paper having an air permeability not higher than 7 CORESTA units (see Japanese Patent No.
- the tobacco burn is made nonuniform because the cigarette paper includes a flame retardant region and a flammable region.
- the smoking taste is made nonuniform.
- the flame spread is lowered by lowering the air permeability of the cigarette paper for this purpose.
- the ventilation effect produced by the cigarette paper is lowered so as to increase the amount of the carbon monoxide (CO) contained in the mainstream smoke, increasing the carbon monoxide/tar ratio (C/T ratio).
- CO carbon monoxide
- C/T ratio carbon monoxide/tar ratio
- an object of the present invention is to provide a cigarette, which is substantially equal to an ordinary cigarette in smoking behavior and in the burn rate, and which permits improving the C/T ratio in the mainstream smoke and exhibits low flame spread.
- a cigarette achieving the above object can be obtained merely by setting the inherent air permeability of the cigarette paper wrapping the tobacco filler material rod and the amount of the loading material mixed in the cigarette paper at prescribed values.
- the amount of loading material can be decreased as much as possible within the range of maintaining the static burn by setting the inherent air permeability of the cigarette paper to fall within a prescribed range.
- the present invention is based on these findings.
- a cigarette comprising a tobacco filler material rod and a cigarette paper containing pulp and a loading material, wherein the cigarette paper has an inherent air permeability of more than 20 CORESTA units but 80 CORESTA units or less and contains the loading material in an amount of 1.0 to 5.0 g/m 2 .
- the cigarette of the present invention maintains static burn, and can exhibit a low flame spread property such that, when left to stand on a substrate after static burn over a prescribed distance, a median value of a moving distance of a char line of the cigarette paper in an axial direction of the cigarette until the burn of the cigarette is stopped is not larger than 8 mm.
- a cigarette comprising a tobacco filler material rod and a cigarette paper wrapping the rod, wherein the cigarette paper has an air permeability of more than 20 CORESTA units but 80 CORESTA units or less, contains a loading material in an amount of 1.4 to 3.7 g/m 2 and also contains a burn adjusting agent in an amount of 0 to 0.6% by weight, and the tobacco filler material is loaded at a loading density of 130 to 230 mg/cm 3 .
- a cigarette according to the present invention comprises a tobacco filler material rod and a cigarette paper wrapping the tobacco filler material rod.
- the cigarette of the present invention has an outer appearance and shape similar to those of an ordinary cigarette.
- the tobacco filler material rod used in the cigarette of the present invention is formed of, e.g., ordinary shredded tobacco.
- the shredded tobacco may contain expanded tobacco and regenerated tobacco, and the central vein of tobacco leaf.
- the loading density of the shredded tobacco is 130 to 260 mg/cm 3 . If the loading density fails to fall within the range given above, it may sometime become difficult to suppress sufficiently the flame spread even if the tobacco rod is wrapped in the cigarette paper of the present invention. It is more preferable that the loading density of the tobacco filler material is 130 to 230 mg/cm 3 , further preferably 140 to 230 mg/cm 3 .
- the shredding width of the shredded tobacco to be equal to that of ordinary shredded tobacco. However, in view of low flame spread, it is desirable for the shredding width to be relatively large, i.e., 0.5 to 1.5 mm, more preferably 0.8 to 1.2 mm.
- the cigarette paper used in the present invention is based on ordinary pulp such as flax pulp used for forming ordinary cigarette paper and, thus, contains pulp.
- the cigarette paper used in the present invention has an inherent air permeability (the air permeability of the cigarette paper without any perforations made therein) of more than 20 CORESTA units (C.U.) but 80 CORESTA units or less. If the inherent air permeability of the cigarette paper sheet is not higher than 20 CORESTA units, the C/T ratio is increased in the cigarette mainstream smoke that is generated during the smoking stage. On the other hand, if the inherent air permeability of the cigarette paper exceeds 80 CORESTA units, the nonuniformity of the air permeability is increased.
- the inherent air permeability of the cigarette paper is desirably more than 20 CORESTA units but 60 CORESTA units or less, and is more desirably 25 to 55 CORESTA units.
- the cigarette paper may be perforated mechanically or electrically by the ordinary method.
- the air permeability of the wrapping paper having such holes is not particularly limited.
- the cigarette paper of the present invention contains loading materials.
- the loading materials that are generally used can be used, including a carbonate salt such as calcium carbonate or potassium carbonate and a hydroxide such as calcium hydroxide or magnesium hydroxide.
- the loading material is contained in the cigarette paper in an amount of 1.0 to 5.0 g/m 2 . If the amount of the loading material is smaller than 1.0 g/m 2 , the cigarette goes out during static burn. Also, if the loading material is contained in an amount exceeding 5.0 g/m 2 , low flame spread cannot be achieved. It is desirable for the amount of the loading material to be 1.4 to 3.7 g/m 2 , more desirably, 1.6 to 3.3 g/m 2 . Also, the amount of loading material in the cigarette paper is preferably 6 to 25% by weight, more preferably 7 to 21% by weight, and furthermore preferably 8 to 17% by weight.
- the basis weight of the cigarette paper is preferably 17 to 28 g/m 2 . If the basis weight is smaller than 17 g/m 2 , it tends to be difficult to stably manufacture the cigarette paper sheet. Also, if the basis weight exceeds 28 g/m 2 , flame spread tends to be promoted.
- the basis weight of the cigarette paper is more preferably 18 to 25 g/m 2 , furthermore preferably 18 to 22 g/m 2 .
- a burn adjusting agent such as citric acid or its salt (such as sodium salt or potassium salt) to the cigarette paper.
- the content of the burn adjusting agent is preferably 0 to 1.0% by weight. If the amount of burn adjusting agent exceeds 1.0% by weight, the C/T ratio tends to become high.
- the amount of burn adjusting agent is more preferably 0 to 0.6% by weight, furthermore preferably 0.1 to 0.6% by weight.
- the cigarette paper of the present invention by having a tensile strength of 10 to 20 N/15 mm or more, can make cigarettes, without difficulty, even if applied to a high-speed cigarette making machine that permits manufacturing cigarettes at a rate of 8,000 to 12,000 cigarettes/min.
- the tensile strength of the cigarette paper can be controlled by controlling the beating degree of the pulp or by controlling the amount of pulp used for manufacturing the cigarette paper sheet.
- the tensile strength of the cigarette paper increases with increase in the amount of pulp per unit area of the cigarette paper or in the beating degree of the pulp.
- a cigarette low in flame spread, and generating mainstream smoke having a small C/T ratio is obtained in spite of the relatively high inherent air permeability of the cigarette paper by setting the inherent air permeability of the cigarette paper and the amount of the loading material contained in the cigarette paper to fall within the ranges given above. Also, the cigarette of the present invention permits exhibiting a burn rate substantially equal to that of an ordinary cigarette.
- the low flame-spreading property of the cigarette of the present invention may be such that, when left to stand on a substrate (10 superposed filter paper sheets) after static burn over a prescribed distance, a median value of a moving distance of a char line of the cigarette paper in an axial direction of the cigarette until the burn of the cigarette is stopped is not larger than 8 mm, preferably 4 mm or lees (measured according to ASTM E 2187-02b method).
- the most frequently obtained value of the moving distance of the char line noted above may be 8 mm or less, preferably 4 mm or less.
- Shredded tobacco was wrapped in a flax pulp cigarette paper having the specification shown in Table 1 such that the shredded tobacco had the loading density shown in Table 1 so as to fabricate 40 cigarettes for each case.
- Calcium carbonate was used as the loading material
- sodium citrate was used as the burn adjusting agent.
- Flue-cured shredded tobacco or blended shredded tobacco were used as the shredded tobacco.
- Table 1 also shows the inherent air permeability and the tensile strength of the cigarette paper. Incidentally, the tensile strength shown in Table 1 was measured by using a tensile strength tester STROGPAPHE-S manufactured by Toyo Seiki K.K. in accordance with the method specified in Japanese Industrial Standards (JIS) P 8113-1998 (the size of test piece: 15.0 mm X about 250 mm, the gripping distance: 180 ⁇ 2 mm, and the pulling rate: 50 mm/min).
- JIS Japanese Industrial Standards
- the static burn rates of the cigarettes thus fabricated were measured by the ordinary method in respect of the fabricated cigarette. Also, the percent full length burn on 10 superposed filter paper sheets was measured by the method specified in ASTM E2187-02b. Further, measurement was made of the median value of the moving distance of the char line of the cigarette paper in the axial direction of the cigarette after the ignited cigarette was placed on the filer papers until the cigarette burning is stopped (or went out). Table 2 shows the results.
- TPM total particulate matter
- the cigarette fabricated by using the cigarette paper specified in the present invention and tobacco filler materials exhibits excellent low flame spread and a small C/T ratio.
- the present invention provides a cigarette, which permits a smoking behavior similar to that of an ordinary cigarette, also permits a burn rate substantially equal to that of an ordinary cigarette, further permits exhibiting a low flame spread, and is small in C/T ratio in the generated mainstream smoke. Also, since a special band and a special flame retardant substance are not used in the present invention, the cigarette of the present invention continues to produce a prescribed taste under ordinary smoking behavior.
