Definitions

  • the present invention relates to a cigarette filter containing a flavor bead.
  • Flavorants added to cut tobacco include a primary flavorant as a casing sauce, and a secondary flavorant as a top flavor.
  • the components of the secondary flavorant are relatively highly volatile, and are susceptible to pyrolysis. Therefore, the secondary flavorant contained in a cigarette evaporates during storage, which results in a decrease of the flavor during smoking.
  • the secondary flavorant migrates to and is adsorbed on the charcoal filter, which results in a further decrease of the flavor.
  • the charcoal filter having the second flavorant adsorbed has decreased capability to remove the components of tobacco mainstream smoke.
  • Japanese Patent No. 2709077 discloses microcapsulating a secondary flavorant with a natural polysaccharide, and adding the microcapsules to a tobacco filter by a so-called cavity filling process. Since the flavorant is encapsulated in the microcapsules composed of the natural polysaccharide, it will not cause the migration or evaporation of the flavorant during storage, and thus will not deteriorate the capability of the charcoal filter to remove the components of tobacco mainstream smoke.
  • the flavor can be tasted only by crushing or grating them by fingers (application of external force) when smoking.
  • the application of external force is bothersome.
  • the flavor released by the application of external force will not uniformly spread over the filter, which results in erratic taste during smoking.
  • the present invention is intended to provide a cigarette filter which can suppress the evaporation and migration of a flavorant during non-smoking stages, and allow for stable tasting of the flavor during smoking stages without requiring the application of external force.
  • a cigarette filter as defined in claim 1.
  • a flavor bead used in the present invention includes a particulate carrier, a glucan film supported by the particulate carrier, and a flavorant.
  • the flavorant is supported by the flavor bead such that release of flavor from the flavorant is suppressed by the glucan film, but the flavor is released by the glucan film being at least partially dissolved when the glucan film contacts with tobacco mainstream smoke.
  • the glucan film contains the flavorant, and directly covers the surface of the particulate carrier.
  • the flavor bead according to the first embodiment includes the particulate carrier, and the glucan film covering the surface of the particulate carrier and holding the flavorant.
  • the flavorant is a solid flavorant which directly covers the surface of the particulate carrier, and the glucan film covers the solid flavorant film.
  • the flavor beads according to the second embodiment each include the particulate carrier, the menthol film covering the surface of the carrier, and the glucan film covering the surface of the menthol film.
  • the particulate carrier used in the present invention are composed of particles of calcium carbonate or coffee beans.
  • particles having an average particle size of 75 ⁇ m to 2000 ⁇ m, e.g., 75 ⁇ m to 350 ⁇ m may be suitably used.
  • the glucan film is composed of, for example, pullulan, maltodextrin or hydroxypropyl cellulose, and is water-soluble.
  • the flavorant may be one for food or tobacco use.
  • examples of such flavorant include lavender, cinnamon, cardamom, celery, clove, cascarilla, nutmeg, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon, orange, mint, cinnamon, caraway, cognac, jasmine, chamomile, menthol, cassia, ylang ylang, sage, spearmint, fennel, pimento, ginger, anise, coriander, and coffee essential oils.
  • FIG. 1 is an enlarged schematic cross sectional view of a flavor bead 10 according to the first embodiment of the present invention.
  • the flavor bead 10 includes a particulate carrier (core) 12, whose surface is covered by a glucan film 14.
  • the glucan film 14 contains the flavorant.
  • the glucan film 14 containing the flavorant may be formed from an aqueous solution or dispersion of the flavorant and glucan.
  • the flavorant is preferably used in an amount corresponding to 20% or less (but more than 0%) of the weight of the glucan.
  • the glucan film 14 is not particularly limited in its thickness. However, in view of releaseability of the flavor during smoking, the glucan film is preferably formed with glucan in an amount corresponding to 0.25% to 5% of the weight of the finished flavor bead.
  • the flavor bead according to the first embodiment may be produced, for example, by the following method. Namely, the particulate carriers composed of calcium carbonate or the like are charged into a fluidized-bed granulation drier, and an aqueous glucan solution or dispersion containing the flavorant is continuously or intermittently sprayed onto the surface of the particulate carriers while blowing, e.g., warm air at 80°C or lower into the granulation drier, followed by drying. In this case, the carriers are immediately cooled depending on the type of the flavorant or the composition of the glucan solution. In this manner, a glucan film holding the flavorant is formed on the surface of the particulate carrier.
  • the flavorant is contained within the glucan film, which has a low gas permeability, the evaporation and degradation of the flavorant during storage can be suppressed. Only after contact with tobacco mainstream smoke during smoking, the glucan film is partially dissolved mainly by highly polar components (for example, water) in the tobacco mainstream smoke, and releases the flavorant component which disperses into the mainstream smoke, thus allowing stable tasting of the flavor of the flavorant.
  • the flavor bead of the present invention does not require the application of external force to taste the flavor as done in the case of microcapsules.
  • FIG. 2 is an enlarged schematic cross sectional view of a flavor bead 20 according to the second embodiment of the present invention.
  • the entire surface of a particulate carrier (core) 22 is covered by a film 24 of a solid flavorant such as menthol, and the entire surface of the solid flavorant film 24 is covered by a glucan film 26.
  • the solid flavorant film 24 may be formed by finely pulverizing crystals of the solid flavorant such as menthol, mixing the resultant solid flavorant fine particles with the particulate carrier 12, thereby adhering the solid flavorant fine particles to the particulate carrier 22, melting the solid flavorant fine particles on the particulate carrier 22 by heating, and then recrystallizing the solid flavorant by cooling.
  • a crystal growth inhibitor such as a fatty acid, glycerol or propylene glycol be added to the solid flavorant.
  • the crystal growth inhibitor may be used in an amount corresponding to 0.1 to 1.0% of the weight of the solid flavorant such as menthol.
  • the solid flavorant film 14 may contain a flavorant other than the solid flavorant.
  • the solid flavorant film 24 is not particularly limited in its thickness. However, the solid flavorant film 24 is preferably formed with the solid flavorant in an amount corresponding to 1 to 20% of the weight of the finished flavor bead.
  • the glucan film 26 may be formed from an aqueous solution or dispersion of glucan.
  • the glucan film 26 is not particularly limited in its thickness. However, in view of holdability of the flavor of the solid flavorant at non-smoking stages and of releaseability of menthol during smoking, the glucan film 26 is preferably formed with glucan in an amount corresponding to 0.25% to 5% of the weight of the finished flavor bead.
  • the flavor bead according to the second embodiment may be produced by, for example, the following method. Namely, the particulate carriers and fine particles of the solid flavorant crystals, and as necessary, the crystal growth inhibitor and other flavorant are mixed and heated in a ribbon mixer. During the early stages of the mixing, the fine particles of the solid flavorant crystals adhere to the surfaces of the particulate carriers, and the fine particles of the solid flavorant crystals begin melting when the heating temperature reaches the melting point of the solid flavorant (for example, about 42°C for menthol). Stirring and mixing are further continued thereby uniformly applying the molten solid flavorant to the surfaces of the particulate carriers.
  • the melting point of the solid flavorant for example, about 42°C for menthol
  • the particulate carriers are immediately cooled by, for example, cooling the can body of the ribbon mixer, or blowing cold air into the ribbon mixer.
  • the molten solid flavorant is recrystallized by the cooling treatment to cover the surfaces of the particulate carriers as a film.
  • the particulate carriers covered with the solid flavorant films are charged into a fluidized-bed granulation drier, and an aqueous solution or dispersion of glucan is intermittently sprayed onto the particulate carriers while blowing, for example, warm air at 40°C or lower into the granulation drier, followed by cooling. In this manner, a glucan film is formed on the surface of the solid flavorant film formed on the surface of the particulate carrier.
  • the flavor bead according to the second embodiment may also be produced by forming a solid flavorant film on the surfaces of the particulate carriers as described above, and spraying an aqueous solution or dispersion of glucan onto the particulate carriers having the solid flavorant films in a ribbon mixer or a rolling granulator, thereby covering the solid flavorant film with the glucan film, followed by cooling.
  • the solid flavorant film formed on the surface of the particulate carrier is covered by the glucan film, which has a low gas permeability, menthol is prevented from evaporating or adhering to charcoal during storage under ordinary conditions.
  • the glucan film contacts with the hydrophilic components such as water contained in mainstream smoke emitted during smoking of the cigarette, the glucan film is partially deformed and dissolved, whereby the flavor is released from the underlying solid flavorant film and can be tasted.
  • the flavor bead of the present invention does not require the application of external force to taste the flavor as done in the case of microcapsules.
  • a cigarette filter according to the present invention contains the flavor beads .
  • FIGS. 3 and 4 A cigarette provided the filter of the present invention will be described below with reference to FIGS. 3 and 4 .
  • similar elements are designated by the same reference numerals.
  • FIG. 3 is a schematic cross sectional view of a cigarette (filter-tipped cigarette) 30 provided with a cigarette filter according to one embodiment of the present invention.
  • the filter-tipped cigarette 30 includes a cigarette portion 32 composed of a tobacco filler 321 such as cut tobacco wrapped with a cigarette paper 322.
  • the cigarette portion 32 is similar to that included in an ordinary cigarette.
  • a filter portion 34 is attached to one end of the cigarette portion 32.

  • the charcoal filter section 341 is formed by wrapping, e.g., cellulose acetate fibers 341a, in which charcoal particles 341b are dispersed, with a filter wrapping paper 341c.
  • the charcoal filter section 341 is similar to that included in an ordinary charcoal filter.
  • the filter section 342 containing the flavor beads is formed by wrapping, e.g., cellulose acetate fibers 342a, in which flavor beads FB of the present invention are dispersed, with a filter wrapping paper 342b.
  • the filter portion 34 composed of the filter sections 321 and 322 is attached to the cigarette portion 32 with a tipping paper 36.
  • FIG. 4 is a schematic cross sectional view of a cigarette (filter-tipped cigarette) 40 provided with a cigarette filter according to another embodiment of the present invention.
  • a filter portion 42 attached to the cigarette portion 32 with the tipping paper 36 is composed of a charcoal filter section 341 which is directly attached to one end of the cigarette portion 32, and a plain filter section 422 which is provided spaced apart from the charcoal filter section 341.
