Description

Perfume Beads and Cigarette Filters {PERFUMED BEADS AND FILTER FOR CIGARETTE}

The present invention relates to a perfume beads and a cigarette filter comprising the same.

The flavor added to the leaf tobacco includes the first flavor as the casing sauce and the second flavor as the top flavor. The component of the second perfume is relatively high in volatility and susceptible to thermal decomposition. Therefore, in the cigarette having the second perfume, the second perfume is volatilized during storage, the flavor at the time of smoking is reduced, and in the cigarette with the charcoal filter, the second perfume is transferred to and absorbed by the charcoal. Taste decreases The charcoal which adsorb | sucked the 2nd fragrance reduces the component removal ability in the mainstream smoke of tobacco.

Patent No. 2709077 discloses microencapsulating a second fragrance with natural polysaccharides and adding the microcapsules to a tobacco filter by so-called cavity filling. Since the fragrance is enclosed in microcapsules made of natural polysaccharides, the fragrance during storage and volatilization do not occur. Therefore, even when used together with a charcoal filter, the charcoal filter reduces the ability to remove components in the mainstream smoke of tobacco. There is no work.

However, the fragrance in the micronized capsule can be tasted only by pressing with a finger at the time of smoking a cigarette, or rubbing it (by applying an external force). However, the application of external force is cumbersome, and the fragrance spilled by the application of external force is not uniformly distributed throughout the filter, and as a result, the taste during smoking is not constant.

DISCLOSURE OF INVENTION

Therefore, this invention can suppress the volatilization and migration of a fragrance at the time of non-smoking, and provides the fragrance beads and the filter for cigarettes which can taste a taste stably without requiring application of an external force at the time of smoking. For the purpose of

According to one aspect of the present invention, the fragrance beads include a particulate carrier, a glucan membrane supported by the particulate carrier, and a perfume, and the perfume is suppressed from being released by the glucan membrane. At least a portion of the glucan membrane is dissolved by contact with tobacco mainstream smoke, so that the fragrance beads are released so that the fragrance beads are supported.

According to another aspect of the present invention, there is provided a cigarette filter comprising the perfume beads of the present invention.

Best Mode for Carrying Out the Invention

EMBODIMENT OF THE INVENTION Hereinafter, various aspects of this invention are demonstrated, referring drawings. Throughout all drawings, the same element is shown with the same code | symbol.

The perfume beads of this invention contain a particulate support, the glucan membrane supported by the said particulate support, and a fragrance | flavor. The fragrance of the perfume is suppressed by the glucan membrane, but the glucan membrane is supported by the perfume beads so that the fragrance is released by dissolving at least a part of the glucan membrane by contact with the mainstream tobacco smoke. .

In the first aspect of the present invention, the glucan film contains a perfume and directly covers the surface of the particulate carrier. The perfume beads by a 1st aspect are provided with the particulate support and the glucan membrane which covered the surface of the said particulate support, and hold | maintained the fragrance.

In the second aspect of the present invention, the perfume is a solid perfume, which directly covers the surface of the particulate carrier, and the glucan membrane covers the solid perfume film. The perfume beads according to the second aspect includes a particulate carrier, a menthol film provided covering the surface of the carrier, and a glucan film provided covering the surface of the menthol film.

The particulate carrier used in the present invention may be composed of calcium carbonate particles, activated carbon particles, sugar crystal particles (for example, granulated sugar), coffee bean particles and the like. As for a particulate-form carrier, what has an average particle diameter of 75 micrometers-2000 micrometers, for example, an average particle diameter of 75 micrometers-350 micrometers can be used suitably.

The glucan membrane is made of, for example, pullulan, maldextrin, hydroxypropyl cellulose and the like and is water-soluble.

Examples of such flavors include lavender, cinnamon, cardamom, serenity, sperm, cascari, nutmeg, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon, orange, mint Essential oils such as cinnamon, caraway, cognac, jasmine, chamomile, menthol, kasha, mockup, sage, spearmint, fennel, pimento, ginger, anise, coriander and coffee.

1 is an enlarged schematic cross-sectional view of the perfume beads 10 according to the first aspect of the present invention. In the perfume beads 10, the glucan membrane 14 covers the surface of the particulate carrier (nucleus) 12. The glucan membrane 14 contains a fragrance.

The glucan film 14 containing the fragrance can be formed from an aqueous solution or a water dispersion of the fragrance and glucan. In this aqueous solution or aqueous dispersion, the perfume is preferably used in an amount (more than 0%) corresponding to 20% or less of the weight of glucan. Although there is no restriction | limiting in particular in the thickness of the glucan membrane 14, It is preferable to form a glucan membrane using the glucan of the quantity equivalent to 0.25%-5% of the weight of a final perfume beads from a viewpoint of the releasing ability of the fragrance at the time of smoking. Do.

The perfume beads by a 1st aspect can be manufactured by the following method, for example. That is, a particulate carrier such as calcium carbonate is placed in a fluid granulation drier, for example, by blowing a warm air of 80 ° C. or lower, spraying the aqueous solution of glucan or aqueous dispersion containing the fragrance continuously or intermittently onto the surface of the particulate carrier. And dry. In that case, the kind of perfume is rapidly cooled depending on the composition of the glucan solution. In this way, a glucan film holding a fragrance is formed on the surface of the particulate carrier.

In the perfume beads according to the first aspect, since the perfume is contained in the glucan membrane with low gas permeability, it is possible to reduce volatilization and deterioration of the perfume during storage. When the cigarette is in contact with the mainstream smoke at the time of smoking, the glucan membrane is partially dissolved by the mainly high polar component (moisture, etc.) in the mainstream smoke, and the contained fragrance component diffuses in the mainstream smoke, thereby flavoring the flavor. I can taste it stably. The fragrance beads of this invention do not require application of external force like microcapsules in order to taste a taste.

2 is an enlarged schematic cross-sectional view of the perfume beads 20 according to the second aspect of the present invention. The perfume beads 20 are covered with a solid perfume film 24 such as menthol covering the entire surface of the particulate carrier (nucleus) 22, and the glucan film 26 covers the entire surface of the solid perfume film 24. will be.

As described later, the solid perfume film 24 finely powders a solid perfume crystal such as menthol, mixes it with the particulate carrier 12, adheres the solid perfume fine powder to the particulate carrier 22, and this is a particulate carrier. After heat-melting on (22), it can form by recrystallizing by cooling. It is preferable to add crystal growth inhibitors such as fatty acids, glycerin, and propylene glycol to the solid perfume to prevent the growth of solid perfume such as menthol until it becomes columnar crystals. This crystal growth inhibitor can be used in an amount corresponding to 0.1 to 1.0% of the weight of solid perfume such as menthol. In addition, the solid perfume film 14 may contain perfumes other than solid perfume.

Although there is no restriction | limiting in particular in the thickness of the solid perfume film 24, It is preferable to form the solid perfume film 24 with the solid perfume of the quantity corresponded to 1-20% of the weight of a final perfume beads.

The glucan film 26 can be formed from an aqueous solution of glucan, an aqueous dispersion, or the like. Although there is no restriction | limiting in particular in the thickness of the glucan membrane 26, The glucan membrane 26 is a thing of the final perfume beads from the viewpoint of the fragrance | flavorability of the solid fragrance at the time of non-smoking, and the releasing ability of menthol at the time of smoking. It is preferable to form by glucan in the quantity corresponded to 0.25-5% of a weight.

The perfume beads which concerns on a 2nd aspect can be manufactured by the following method, for example. In other words, the fine powder of the particulate carrier and the solid perfume crystal and, if necessary, the crystal growth inhibitor and the other perfume are mixed and heated with a ribbon mixer. At the beginning of this mixing, the fine powder of the solid perfume crystal adheres to the surface of each particulate carrier, and the fine powder of the solid perfume crystal starts to melt at a temperature where the heating temperature reaches the melting point of the solid perfume (for example, about 42 ° C in menthol). do. By continuing the stirring mixing, the molten solid perfume is uniformly applied to the surface of each particulate carrier. After this warm mixing, the particulate carrier is rapidly cooled by, for example, cooling the ribbon mixer tube or blowing cold air into the ribbon mixer. By this cooling, the molten solid perfume can be recrystallized and the surface of each particulate carrier can be covered with a film. The particulate carrier covered with the solid fragrance film is placed in a fluid granulation dryer, and is sprayed intermittently with an aqueous solution of glucan or an aqueous dispersion of glucan, for example, while blowing a warm air of 40 ° C. or lower. In this way, a glucan film is formed on the surface of the solid perfume film formed on the surface of the particulate carrier.

Alternatively, as described above, after the solid perfume film is provided on the surface of the particulate carrier, the aqueous solution or aqueous dispersion of glucan is sprayed onto the particulate carrier having the solid perfume film in a ribbon mixer or in an electric granulator as it is, and the solid perfume film is coated with the glucan film. After covering with, the perfume beads according to the second aspect can be produced by cooling.

In the perfume beads according to the second aspect, since the solid perfume film provided on the surface of the particulate carrier is covered by a glucan membrane with low gas permeability, menthol is not volatilized or adsorbed by charcoal during normal storage. . When it comes into contact with hydrophilic components such as water in mainstream smoke generated by smoking a cigarette, the glucan membrane changes in part and dissolves, and the fragrance is released from the lower solid perfume membrane, thereby allowing the flavor of the perfume to be tasted. . The fragrance beads of this invention do not require application of external force like microcapsules in order to taste a taste.
