Abstract
Description
- The present invention relates to a cigarette package. More particularly, it relates to a cigarette package which does not significantly reduce the amount of a volatile flavor delivered into the mainstream smoke of the cigarette when it is smoked.
- Cigarettes are accommodated in a package to be stored and sold. The package is formed of an outer pack and an inner pack which is accommodated in the outer pack and directly wraps a cluster of cigarettes. The outer pack is covered with a thin resin film.
- Incidentally, many currently sold cigarettes comprise a filter. Cellulose acetate is used as a material for the filter. Cellulose acetate is very excellent in filtrating and sorbing components of the mainstream smoke of the cigarette, however it also sorbs a volatile flavor component such as menthol contained in the cigarette. Thus, even if the cigarettes are accommodated in the package and stored, the amount of the volatile flavor delivered into the mainstream smoke of the cigarette when it is smoked is reduced by the sorption by the cellulose acetate as the storage period becomes longer. The reduction rate tends to be higher as the temperature during storage is higher.

Patent Literature 1 discloses that cigarettes are wrapped with a packaging material containing glycerol ester and/or propylene glycol to suppress the volatilization of the flavor in the cigarettes after opening the package. However, volatilization of the flavor when the cigarettes accommodated in an unopened package are exposed to high temperatures is not examined. -

Usually, the volatile flavor is 1-menthol. The volatile flavor may be added to, for example, a tobacco filler, a filter or both of them. Needless to say, a plurality of packages to be accommodated in one package is produced in the same specification.
- The porous polysaccharide gel which is accommodated together with cigarettes in the cigarette package contains the same flavor as the volatile flavor contained in the cigarette.
- Polysaccharides such as carrageenan, agar, gellan gum, tamarind gum, psyllium seed gum, and konnyaku glucomannan may be used singly. Alternatively, two or more polysaccharides selected from the group consisting of carrageenan, locust bean gum, guar gum, agar, xanthan gum, gellan gum, tamarind gum, tara gum, konnyaku glucomannan, starch, cassia gum, and psyllium seed gum may be used in combination. A mixture of gellan gum and tamarind gum is preferred. Since these polysaccharides can gel by only heating, it is not necessary to use gelling agent for allowing the polysaccharide to gel.

cigarettes 20 is directly wrapped with theinner pack 130 formed of a paper sheet lined with aluminium and accommodated in thebox body 12. Each of thecigarettes 20 has a cigarette rod 201 comprising a tobacco filler rod wrapped with a cigarette paper (not shown). Afilter 202 is attached to one end of the cigarette rod. Thecigarettes 20 are, for example, menthol cigarettes, in which menthol is added to the tobacco filler or the filter. - The volatile-flavor-containing polysaccharide gel porous sheet of the present invention is accommodated in the
cigarette box 12. For example, the porous sheet can be attached to thefront wall 121 of the box body, therear wall 122, theside walls bottom wall 125 using an appropriate adhesive. The porous sheet can be attached to thefront wall 141 of thelid 12, therear wall 142, theside walls 143 and 144 and/or the inner surface of thetop wall 145, in place of or in addition to the inner surface of the box body. InFIG. 1 , a volatile-flavor-containing porouspolysaccharide gel sheet 40 of the present invention is attached to the inner surface of thetop wall 145 of thelid 14. Thecigarette box 10 is usually wrapped with a thin resin film (not shown). -
FIG. 2 shows the same cigarette package shown inFIG. 1 except that a volatile-flavor-containing porouspolysaccharide gel sheet 41 of the present invention is simply inserted into a space between the inner surface of thefront wall 121 of thebox body 12 and the front wall of the inner pack 130 (not adhered to any portion of the cigarette package). - Since the cigarette package of the present invention accommodates the volatile-flavor-containing porous polysaccharide gel, even if it is kept under high temperatures (for example, even if it is placed in a vending machine in summer), the amount of the volatile flavor delivered into the mainstream smoke of the cigarette is not substantially reduced. Examples
- In this example, as polysaccharides, gellan gum (trade name: Kelcogel, manufactured by CP Kelco) and tamarind gum (trade name: Bistop D-2032, manufactured by San-Ei Gen F.F.I., Inc.) were used. As the flavor, l-menthol (reagent menthol, Wako Pure Chemical Industries, Ltd.) was used. As the emulsifier, lecithin (trade name: Sunlecithin A-1, Taiyo Kagaku Co., Ltd.) was used.
- 1 g of gellan gum and 1 g of tamarind gum were added to 100 mL of water and dissolved by heating in a constant temperature water bath at 80°C. 10 g of 1-menthol and 1.6 mL of 5% lecithin aqueous solution were added and the mixture was emulsified with a homogenizer (high-performance mixer DMM, A-Tech Japan). The obtained emulsified slurry was extended into a sheet on a stainless plate and the resulting sheet was dried in a forced-air-circulation drier (EPSF116, manufactured by Isuzu) at 40°C for one week. It was analyzed that the thus obtained dry sheet contained about 85% by weight of menthol. An SEM (JSM5310, manufactured by JEOL Ltd.) photograph of the dry sheet is shown in
FIG. 3 . The dry sheet was placed in a beaker and heated in a microwave oven (ER-V11 (W), manufactured by Toshiba Corporation) at 500 W for 30 seconds to obtain a porous menthol sheet. An SEM (JSM5310, manufactured by JEOL Ltd.) photograph of the obtained porous menthol sheet is shown inFIG. 4 . - The following experiments were performed using or not using the obtained porous menthol sheet.
- Experiment 1: Only commercially available menthol cigarettes with a cellulose acetate filter (about 6 mg of menthol has been added to the shredded tobacco; in this regard, when the distribution state of the menthol was measured immediately before the start of the present experiment, about 4.5 mg of menthol was present in the shredded tobacco and about 1.5 mg of menthol was present in the filter) were placed in sealed glass containers, which were stored at 22°C for 13 days and for 28 days. Thereafter, the cigarettes were automatically smoked and the amount of menthol in the cigarette smoke was measured.
- Experiment 2: Commercially available menthol cigarettes with a cellulose acetate filter (about 6 mg of menthol has been added to the shredded tobacco) and the porous menthol sheet were placed in sealed glass containers, which were stored at 22°C for 13 days and for 28 days. Thereafter, the cigarettes were automatically smoked and the amount of menthol in the cigarette smoke was measured.
- Experiment 3: Only commercially available menthol cigarettes with a cellulose acetate filter (about 6 mg of menthol has been added to the shredded tobacco) were placed in sealed glass containers, which were stored at 55°C for 13 days and for 28 days. Thereafter, the cigarettes were automatically smoked and the amount of menthol in the cigarette smoke was measured.
- Experiment 4: Commercially available menthol cigarettes with a cellulose acetate filter (about 6 mg of menthol has been added to the shredded tobacco) and the porous menthol sheet were placed in sealed glass containers, which were stored at 55°C for 14 days and for 28 days. Thereafter, the cigarettes were automatically smoked and the amount of menthol in the cigarette smoke was measured.
- In automatically smoking the cigarettes, a 20-port linear smoking machine (SM400; ISO authentic machine, manufactured by Filtrona) was used. The puff time was 2 seconds per puff, the puff volume was 35 mL, and the puff interval was 60 seconds. The cigarette was burnt by a length of 53 mm from the distal end thereof. The smoke was collected in a gas bag and the amount of menthol in the smoke was measured by a gas chromatograph (6890N, manufactured by Agilent Technologies Inc.). The results (the amount of menthol in the cigarette smoke per cigarette) are shown in
FIG. 5 . InFIG. 5 , the results ofExperiment 1 are indicated by a white rhombus, the results of Experiment 2 are indicated by a black rhombus, the results of Experiment 3 are indicated by a white triangle, and the results of Experiment 4 are indicated by a black triangle. - As shown in
FIG. 5 , in the case where the menthol cigarette was stored at 22°C, there was no great difference in the amount of menthol in the cigarette smoke between when the porous menthol sheet was coexistent and when it was not coexistent. However, in the case where the menthol cigarette was stored at 55°C, when the porous menthol sheet was not coexistent, the amount of menthol in the cigarette smoke was significantly reduced as compared to the initial amount. However, when the porous menthol sheet was coexistent, the amount of menthol in the cigarette smoke was hardly reduced. These results strongly suggest that the porous menthol sheet releases a small amount of menthol at an ordinary temperature (30°C or less), however it releases a large amount of menthol at high temperatures (50°C or more).
