Definitions
- the present invention relates to a low flame-spreading cigarette paper, and particularly, to a cigarette paper exhibiting both a low flame-spreading property and a low C/T ratio.
- a cigarette paper provided with bands formed of a flame retardant substance coated on a base cigarette paper is proposed (Jpn. Pat. Appln. KOKAI Publication No. 7-300795), in order to hardly cause the flame to spread from the kindling to, e.g., the floor when the cigarette is dropped on the floor through, for example, the carelessness of the smoker.
- This technique is based on the idea that when regions having a high combustibility and regions having a low combustibility are formed on a cigarette paper, the ordinary smoking can be performed at the region having a high combustibility, but, if a substance is brought into contact with the cigarette at the regions having a low combustibility, the cigarette is self-extinguished.
- a cigarette paper exhibiting a low flame-spreading property comprising, on one surface of a base cigarette paper containing a filler in an amount of 2 to 6 g/m 2 and having a basis weight of 16 to 22 g/m 2 , burn-suppressing regions coated with a burn-suppressing agent, provided spaced apart from each other, wherein a total coating amount of the burn-suppressing agent corresponds to 0.2 to 1.8 g per m 2 of the coated portion.
- the single FIGURE is a schematic oblique view, partly broken away, exemplifying a construction of a cigarette wrapped with a cigarette paper according to one embodiment of the present invention.
- burn-suppressing regions coated with a burn-suppressing agent are formed apart from each other on one surface of a base cigarette paper.
- the base cigarette paper is based on an ordinary pulp such as flax pulp that is generally used for cigarette papers.
- the base cigarette paper contains a filler in an amount of 2 to 6 g/m 2 , and has a basis weight of 16 to 22 g/m 2 .
- filler use may be made of materials that are used generally including, for example, carbonates such as calcium carbonate and potassium carbonate, and hydroxides such as calcium hydroxide and magnesium hydroxide.
- a burn adjusting agent such as citric acid or a salt thereof (sodium salt or potassium salt) may be added to the cigarette paper.
- These burn-adjusting agents, if added, may be used in an amount of up to 2% by weight in the base cigarette paper.
- burn-suppressing regions which are formed by coating of a burn-suppressing agent, are provided apart from each other.
- the burn-suppressing regions may be provided in the form of a plurality of stripes such that when a tobacco rod is wrapped with the cigarette paper, they extend in the longitudinal direction of the tobacco rod and are spaced apart from each other in the circumferential direction of the tobacco rod.
- the burn-suppressing regions may be provided in the form of a plurality of annular rings such that they extend in the circumferential direction of the tobacco rod and are spaced apart from each other in the longitudinal direction of the tobacco rod.
- the total coating amount of the burn-suppressing agent (dry basis) corresponds to 0.2 to 1.8 g/m 2 per m 2 of the coated region.
- the burn-suppressing agent use may be preferably made of, for example, proteins such as gelatin, casein, albumin, and gluten; polysaccharides exhibiting a viscosity-increasing property such as starch, xanthan gum (echo gum), locust bean gum, guar gum (guar pack), tragacanth gum, tamarind seed polysaccharide (glyroid), karaya gum, gum arabic, pullulan, dextrin, cyclo dextrin (Oligoseven), and gutty; polysaccharides exhibiting a gelling property such as carrageenan, curdlan, agar-agar, gelatin, farselran, pectin, juran gum, and Kelco Gel; a lipid such as lecithin; natural polymer derivatives such as sodium alginate, carboxymethyl cellulose, methyl cellulose, propylene glycol alginate ester, and processed starch (such as starch phosphate
- finely pulverized cellulose, microcrystalline cellulose, flax pulp, and wood pulp have similar effects. These burn-suppressing agents can be used singly or in combination of two or more of these.
- Sodium alginates having various degrees of polymerization are commercially available. In the present invention, sodium alginate having a polymerization degree of 500 to 900 is preferred. Sodium alginate having such a high degree of polymerization exhibits a high burn-suppressing effect even when used in a small amount.
- the low flame-spreading property and the low C/T ratio can be exhibited at the same time by setting the amount of the filler in the base cigarette paper, the basis weight of the base cigarette paper, and the total coating amount of burn-suppressing agent within the ranges described above.
- the low flame-spreading cigarette paper of the present invention is used to wrap a tobacco rod formed of, for example, tobacco shreds, and generally, the surface on which the burn-suppressing agent is coated is brought into contact with the tobacco rod.
- FIG. 1 illustrates a cigarette wrapped with a cigarette paper on which a burn-suppressing agent is coated in the form of annular rings.
- a cigarette 10 comprises a tobacco rod 11 consisting of a tobacco filler 13 that is wrapped with a base cigarette paper 12 in the form of a column.
- the base cigarette paper 12 may have an inherent air permeability of about 10 to 100 CORESTA units.
- the tobacco rod 11 has a circumference of 17 to 26 mm and a length of 49 to 90 mm.
- An ordinary filter 18 may be attached to the proximal end portion (i.e., downstream edge portion in the inhaling direction) of the tobacco rod 11 by using a chip paper 17 according to the ordinary method.
- annular region 14 coated with a burn-suppressing agent is formed on the base cigarette paper 12 , defining a burn-suppressing region. Where a plurality of annular burn-suppressing regions 14 are formed as illustrated in FIG. 1 , these annular regions 14 are formed apart from each other in the longitudinal direction of the tobacco rod.
- An ordinary burn region 15 that is not coated with a burn-suppressing agent is formed between adjacent annular burn-suppressing regions 14 . Since the region 15 is constituted by a part of the base cigarette paper 12 , it can burn under the ordinary smoking state like the base cigarette paper 12 itself. It follows that the region 15 acts as an ordinary burn region. For example, it is possible to form 1 to 3 annular burn-suppressing regions 14 . Also, the annular burn-suppressing region 14 may have a width of 4 to 7 mm in the longitudinal direction and generally have a thickness of 0.1 to 5 ⁇ m. Where a plurality of burn-suppressing regions 14 are formed, distance between the adjacent burn-suppressing regions 14 is preferably 18 to 25 mm.
- a region 16 covering a distance d from the tip is not coated with a burn-suppressing agent.
- This section at the tip portion, which is not coated with the burn-suppressing agent, also constitutes an ordinary burn region, and can correspond to the region that is combusted by one puff or two puffs in the ordinary cigarette.
- the distance d from the tip 11 a of the tobacco rod can be set at 10 to 25 mm. It is not particularly necessary to form a burn-suppressing region 14 on the inner surface of the cigarette paper corresponding to that portion of the cigarette paper 12 which is covered with the chip paper 17 .
- the cigarette 10 When the cigarette 10 is ignited at the tip 11 a and inhaled to be burnt, the cigarette can burn at the ordinary burn region 15 like an ordinary cigarette and the flavor and taste can be enjoyed. However, if the cigarette 10 under the ignited state is put on a combustible material such as a carpet, a tatami mat, a wooden article, cloths, or clothing, the burn-suppressing region 14 extending in the combusting direction, the heat absorption by the combustible substance, and the expanded tobacco shreds collectively serve to extinguish the cigarette 10 , and prevent the combustible substance from catching fire. Also, the cigarette wrapped with the cigarette paper of the present invention is low in the C/T ratio in the mainstream smoke.
- a base paper (width 27 mm; length 1.500 m) of the specification shown in Table 1 was coated (printed) with an aqueous solution of sodium alginate of various concentrations (0.5 to 20% by weight) at a constant width of 7 mm in the longitudinal direction and a constant spacing of 20 mm in the form of stripes by a direct gravure method, forming a total of 56 burn-suppressing agent-coated regions.
- the total coating amount of sodium alginate was measured according to the procedures described below. The results are shown also in Table 1.
- the total coating amount of the burn-suppressing agent per m 2 of the region coated with the burn-suppressing agent corresponded to 0.2 to 1.8 g in the papers of Examples 1 to 13.
- This coating amount of the burn-suppressing agent can be converted to the amount of the burn-suppressing agent per area of the cigarette paper by being multiplied by 7/27, yielding 0.05 to 0.47 g/m 2 .
- sodium alginate used in each of Examples 5, 8 and 11 was I-S manufactured by KIMIKA (registered trademark) (polymerization degree: 650 to 670; viscosity of its 3% by weight aqueous solution at 25° C.: 29976.9 cP), and sodium alginate used in each of the other Examples was IL-2 manufactured by KIMIKA (registered trademark) (polymerization degree: 30 to 180; viscosity of its 3% by weight aqueous solution at 25° C.: 907.2 cP).
- a tobacco rod consisting of American blend of tobacco shreds (tar amount without a filter: 19 to 20 mg) was wrapped with the cigarette paper obtained above, and was cut such that the first coated region was arranged 5 mm spaced apart from the burn edge of the cigarette.
- Each cigarette was 59 mm long, and had two burn-suppressing agent-coated regions.
- the cigarette thus obtained was subjected to a burn test in accordance with ASTM E-2187-04 so as to measure the value of PFLB (percent full-length burn). Also, the CO amount in the mainstream smoke, the number of puffs and the tar amount for each cigarette sample were measured by the methods described below in respect of these cigarette samples. The results are shown in Table 2.
- the cigarette paper coated with the burn-suppressing agent (1.5000 m; width 27 mm) (about 1.0 g) was cut into pieces each sized at 5 mm square. Then, 40 mL of a 1% by weight aqueous solution of sodium hydrogen carbonate was added thereto, and heated for 5 minutes in a warm water bath at 60° C. Then, the mixture was sufficiently mixed, stirred, and subjected to centrifugal separation (3,500 rotations, 10 minutes; the same applies to the following) to give a supernatant liquor (extracted liquid). The extraction residue was similarly subjected again to the extraction to give a supernatant liquor (extracted liquid).
- the tobacco smoke was collected by using an 8-port linear smoking machine (SM 342) manufactured by FILTRONA Inc.
- SM 342 8-port linear smoking machine
- the suction of 35 mL/2 seconds was carried out at an interval of 60 seconds according to the ISO standards, and the smoke passing through the glass fiber filter was collected in a gas bag.
- the suction of the cigarette sample was stopped when the sample reached the standard burn length (51 mm from the ignition edge of the cigarette (8 mm apart from the tip side as measured from the boundary between the cigarette paper and the chip paper)).
- the number of puffs at this point was counted and recorded.
- the igniting portion was removed and, then, blank puffing was performed three times so as to collect the gas remaining in the cigarette. In this fashion, the gas of the cigarette sample was collected in the gas bag, and the total particulate matter (TPM) was collected at the glass fiber filter.
- TPM total particulate matter
- the CO amount per cigarette sample was measured with a CO measuring apparatus manufactured by FILTRONA Inc., using the gas collected in the gas bag and
- the crude tar amount was weighed, and then the filter was put in a serum bottle and vigorously shaken together with 10 mL of 2-propanol (GC grade, manufactured by Wako Junyaku K.K.). The extracted liquor was filtered and poured into a vial. Then, the extracted liquor was applied to a chromatograph so as to measure the water amount and the nicotine amount. The quantitative determination was carried out by the internal standard method, and the tar amount was obtained by subtracting the water amount and the nicotine amount from the crude tar amount.
- 2-propanol GC grade, manufactured by Wako Junyaku K.K.
- the present invention provides a cigarette paper which exhibits a low flame-spreading property and achieves a low C/T ratio.
