Description

  The present invention relates to a cigarette package, and more particularly to a cigarette package that, when smoked, does not significantly reduce the amount of volatile fragrance delivered in cigarette mainstream smoke.

  Cigarettes are stored and sold in packages. The package consists of an outer pack and an inner pack that is contained within the outer pack and directly wraps the cigarette bundle. The outer pack is covered with a thin resin film.

  By the way, many of the cigarettes currently sold are equipped with a filter, and cellulose acetate is used as the filter material. Cellulose acetate is extremely excellent in the filtration and sorption of cigarette mainstream smoke components, but also sorbs volatile perfume components such as menthol contained in cigarettes. Therefore, even if cigarettes are stored in a package and stored, the amount of volatile fragrance delivered to the mainstream smoke when smoking decreases due to sorption by cellulose acetate, as the storage period increases, The decreasing rate tends to increase as the temperature during storage increases.

  Patent Document 1 discloses wrapping a cigarette with a packaging material containing glycerin ester and / or propylene glycol in order to suppress the volatilization of the fragrance in the cigarette after the package is opened. However, the fragrance volatilization when the cigarette accommodated in the package which is not opened is exposed to high temperature is not examined.

Usually, the volatile perfume is l-menthol. Volatile fragrances can be added, for example, to tobacco fillers, filters, or both. Needless to say, a plurality of packages housed in one package are manufactured with the same specifications.

  The porous polysaccharide gel accommodated with the cigarette in the cigarette package contains the same fragrance as the volatile fragrance contained in the cigarette.

  As polysaccharides, carrageenan, agar, gellan gum, tamarind gum, psyllium seed gum or konjac glucomannan alone or carrageenan, locust bean gum, guar gum, agar, xanthan gum, gellan gum, tamarind gum, tara gum, konjac glucomannan, starch Two or more polysaccharides selected from the group consisting of cassia gum and psyllium seed gum can be used in combination. A mixture of gellan gum and tamarind gum is preferred. Since these polysaccharides can be gelled only by heating, a gelling reaction agent for gelling the polysaccharide is unnecessary.

Such a porous polysaccharide gel can be produced by subjecting the perfume-containing polysaccharide gel disclosed in WO2009 / 142159A1 to microwave heating.

  That is, first, the polysaccharide is dissolved in water while being heated to a temperature of 60 to 90 ° C., for example. A volatile fragrance and an emulsifier are added to the obtained aqueous solution and kneaded and emulsified at the above temperature to obtain an emulsified slurry. As the emulsifier, for example, lecithin, sucrose fatty acid ester, glycerin fatty acid ester, sorbitan fatty acid ester and the like can be used.

  The emulsified slurry is then cast on a suitable support and dried to evaporate the water. Drying is performed at a relatively low temperature of, for example, 30 ° C to 40 ° C. The obtained dry polysaccharide gel (sheet) can contain volatile fragrances in an amount of preferably 18% by weight or more, more preferably 60% by weight or more, particularly 70% by weight or more. The content of the volatile fragrance is usually 85% by weight or less. As described in WO2009 / 142159A1, the dried polysaccharide gel containing the volatile fragrance thus obtained hardly releases volatile fragrance even when exposed to a high temperature of 50 ° C., for example.

  Next, the obtained volatile flavor-containing dry polysaccharide gel is subjected to microwave heating. By this microwave heating, the dried gel becomes porous. Microwave heating is a heating method in which heat is generated from the inside of a substance by the interaction between the microwave and the substance. Microwave heating is conveniently performed using a microwave oven. The volatile perfume-containing dry polysaccharide gel can be heated, for example, in a microwave oven with a frequency of 2.45 GHz and an output of 500 W (5 A) for 20 seconds to 40 seconds. That is, microwave energy corresponding to a microwave oven having a frequency of 2.45 GHz and an output of 500 W (5 A) can be applied to the volatile perfume-containing dry polysaccharide gel for 20 seconds to 40 seconds. As described above, by this microwave heating, the volatile perfume-containing dry polysaccharide gel becomes porous. The resulting porous polysaccharide gel releases only a small amount of volatile fragrance such as menthol at room temperature (30 ° C or lower), but releases a large amount of volatile fragrance such as menthol at high temperature (50 ° C or higher). Shows temperature-dependent specificity. The volatile perfume-containing porous polysaccharide gel has a plurality or many pores having a size of 100 μm or less, for example. The volatile fragrance-containing porous polysaccharide gel exhibits a porosity that does not significantly reduce the amount of volatile fragrance delivered in the mainstream smoke of cigarette even when the cigarette contained in the package is exposed to high temperature. The porous polysaccharide gel preferably contains volatile fragrance in an amount of 1% or more, usually 10 to 50% of the total amount of volatile fragrance contained in a plurality of cigarettes contained in a cigarette package.

  As mentioned above, the volatile fragrance | flavor containing porous polysaccharide gel of this invention is accommodated in a cigarette package. The porous polysaccharide gel can be accommodated in the cigarette package in the form of a sheet, a lump or the like. For example, a sheet of porous polysaccharide gel can be adhered to cover at least a portion of the inner surface of the outer pack. Alternatively, a sheet of porous polysaccharide gel can simply be inserted into the space formed between the outer pack and the inner pack.

  FIG. 1 is a schematic perspective view showing a hinge lid type cigarette box 10. The cigarette box 10 includes an outer box body 12 and a lid (hinge lid) 14 that is pivotally connected to the box body 12 that opens and closes and opens and closes the opening end of the box body 12. The box body 12 has a front wall 121, a rear wall 122, side walls 123 and 124, and a bottom wall 125. The front wall 121 of the box body 12 is partially cut away (121a) from the upper end. The lid 14 is connected to the rear wall 122 of the lid via a hinge 27 (not shown). The lid 14 has a front wall 141, a rear wall 142, side walls 143 and 144, and a top wall 145. In FIG. 1, the lid 12 is open so that the cigarette 20 in the box can be seen. Similarly, an inner pack 130 described later is also open. The inner pack 130 is partially broken so that the cigarette 20 can be seen.

  A bundle of cigarettes 20 is directly wrapped by an inner pack 130 made of a paper sheet lined with aluminum and accommodated in the box body 12. Each cigarette 20 is provided with a cigarette rod 201 in which a cigarette filler rod is wrapped with wrapping paper (not shown), and a filter 202 is attached to one end of the cigarette rod. Cigarette 20 is, for example, menthol cigarette, and menthol is added to a tobacco filler or filter.

  In the cigarette box 12, the volatile fragrance | flavor containing polysaccharide gel porous sheet of this invention is accommodated. For example, the porous sheet can be attached to the inner surface of the front wall 121, the rear wall 122, the side walls 123, 124 and / or the bottom wall 125 of the box body with a suitable adhesive. Instead of or in addition to the inner surface of the box body, the porous sheet may be attached to the inner surface of the front wall 141, the rear wall 142, the side walls 143, 144 and / or the top wall 145 of the lid 12. In FIG. 1, the volatile perfume-containing porous polysaccharide gel sheet 40 of the present invention is attached to the inner surface of the top wall 145 of the lid 14. The cigarette box 10 is usually wrapped with a thin resin film (not shown).

  FIG. 2 shows that the volatile perfume-containing porous polysaccharide gel sheet 41 of the present invention is simply inserted into the space between the inner surface of the front wall 121 of the box body 12 and the front wall of the inner pack 130 (in the cigarette package). A cigarette package similar to the cigarette package shown in FIG. 1 is shown except that it is not adhered to any part.

  Since the cigarette package of the present invention contains a volatile perfume-containing porous polysaccharide gel, it can be stored at high temperatures (for example, placed in a vending machine in the summer) or in the mainstream smoke of cigarettes. The amount of volatile fragrance delivered from the cigarette to the lip is not substantially reduced.

Example 1
In this example, gellan gum (manufactured by CP Kelco, trade name: Kelcogel) and tamarind gum (manufactured by Saneigen FFI, trade name: Bistop D-2032) are used as polysaccharides, and l as a fragrance. -Menthol (Wako Pure Chemicals, reagent menthol) was used, and lecithin (Taiyo Kagaku, trade name: San lecithin A-1) was used as an emulsifier.

  1 g of gellan gum and 1 g of tamarind gum were added to 100 mL of water and heated in a constant temperature water bath at 80 ° C. to dissolve. To this solution, 10 g of 1-menthol and 1.6 mL of a 5% aqueous solution of lecithin were added, and the mixture was emulsified with a homogenizer (Atec Japan, High Performance Mixer DMM). The obtained emulsified slurry was spread in a sheet form on a stainless steel plate and dried at 40 ° C. for 1 week with an air forced circulation dryer (EPSF116 manufactured by Isuzu). The dried sheet thus obtained was analyzed to contain about 85% by weight of menthol. An SEM (JEOL JSM5310) photograph of this dried sheet is shown in FIG. The dried sheet was transferred into a beaker and heated with a microwave oven (ER-V11 (W) manufactured by Toshiba) at 500 W for 30 seconds to obtain a porous menthol sheet. The SEM (JSMOL JSM5310) photograph of the obtained porous menthol sheet is shown in FIG.

  The following experiment was conducted with or without using the obtained porous menthol sheet.

  Experiment 1: Commercially available menthol cigarette with cellulose acetate filter in a sealed glass container (about 6 mg of menthol was added to the tobacco cut; however, when the distribution of menthol was measured immediately before the start of this experiment, menthol was about 4 (5 mg, found to be present in filter about 1.5 mg) and stored at 22 ° C. for 13 and 28 days, the cigarettes were allowed to smoke automatically and the amount of menthol in tobacco smoke was measured.

  Experiment 2: A commercially available menthol cigarette with a cellulose acetate filter (added approximately 6 mg of menthol to tobacco) and the porous menthol sheet were placed in a sealed glass container and stored at 22 ° C. for 13 and 28 days. Was automatically smoked, and the amount of menthol in the tobacco smoke was measured.

  Experiment 3: Put a menthol cigarette with commercially available cellulose acetate filter (added about 6 mg of menthol in tobacco) into a sealed glass container and store it at 55 ° C for 13 and 28 days. The amount of menthol in tobacco smoke was measured.

  Experiment 4: A commercially available menthol cigarette with a cellulose acetate filter (added about 6 mg of menthol in tobacco) and the above porous menthol sheet were placed in a sealed glass container and stored at 55 ° C. for 14 and 28 days. Was automatically smoked, and the amount of menthol in the tobacco smoke was measured.

  For cigarette automatic smoking, use a 20-line linear smoker (Filtrona SM400; ISO standard device), the puff time is 2 seconds per puff, the puff capacity is 35 mL, and the puff interval is It was 60 seconds. The cigarette was burned for a length of 53 mm from the tip of the cigarette. Smoke was collected in the gas bag, and the amount of menthol in the smoke was measured by a gas chromatograph (manufactured by Agilent, 6890N). The results (amount of menthol in cigarette smoke per cigarette) are shown in FIG. In FIG. 5, the results of Experiment 1 are indicated by white diamonds, the results of Experiment 2 are indicated by black diamonds, the results of Experiment 3 are indicated by white triangles, and the results of Experiment 4 are indicated by black triangles.

  As shown in FIG. 5, when menthol cigarettes are stored at 22 ° C., there is no great difference in the amount of menthol in tobacco smoke, whether or not the porous menthol sheet coexists. However, when menthol cigarettes are stored at 55 ° C, the amount of menthol in tobacco smoke is greatly reduced compared to the initial amount when no porous menthol sheet coexists, but the porous menthol sheet coexists. The amount of menthol in tobacco smoke is hardly reduced. These results strongly suggest that the porous menthol sheet releases a small amount of menthol at room temperature (30 ° C. or lower), but releases a large amount of menthol at a high temperature (50 ° C. or higher).
