Description

    TECHNICAL FIELD
  • The present invention relates to a filter containing built-in capsule in which a tobacco flavor enhancing liquid that can enhance flavor aspects such as taste, aroma, and richness is encapsulated, along with a cigarette and cigarette substitute comprising this filter.
    • BACKGROUND OF THE INVENTION
  • Smokers conventionally smoke cigarettes for a variety of reasons (for example, relaxing, socializing, simple addiction, etc.). Under such circumstances, with antismoking campaigns having become widespread in recent years, numerous smokers who do not want to stop smoking instead continue to smoke low-tar and low-nicotine cigarettes.
  • However, in changing their daily cigarettes to low-tar and low-nicotine cigarettes, smokers feel that the latter cigarettes are actually weak in taste, light, and do not provide a sense of smoking, etc., causing them return to smoking high-tar and high-nicotine cigarettes.
  • On the other hand, Patent Document 1 described below discloses a smoking device with the object of providing an actual low-tar cigarette that provides the same sensation as if smoking a high-tar cigarette. This smoking device includes an additional sensory irritation component at the end of the mouthpiece of the cigarette, with a bittering agent used as this sensory irritation component.
  • However, according to this smoking device, as the sensory irritation component is directly added to the tip paper, this component is in continuous contact with the air. Therefore, it tends to vaporize, resulting in the problem of the taste and aroma likely being lost. In addition, when smokers hold a cigarette, it stimulates the senses directly via the mouth, making it impossible to distinguish between low-tar and high-tar depending on their current mood, etc. Therefore, it does not sufficiently satisfy the taste of smokers as described above.
    • PRIOR ART DOCUMENTS Patent Document
  • Patent Document 1: Japanese Unexamined Patent Application Publication No. 2009-148233
    • BRIEF SUMMARY OF THE INVENTION Problems to be Solved by the Invention
  • The present invention has been created in order to solve such problems, with the object thereof to provide a filter containing built-in capsule that provides, as required, the sensation of a high-tar and high-nicotine cigarette having flavor aspects such as taste, aroma, and richness even in low-tar and low-nicotine cigarettes, along with a cigarette and a cigarette substitute comprising this filter.
    • Means for Solving the Problems
  • As a means of achieving said object, the present invention provides a filter containing built-in capsule, wherein an easily breakable capsule is incorporated in a filter and a tobacco flavor enhancing liquid is encapsulated in a film of this capsule, with the liquid including natural cacao extract but not nicotine and tar, and the cacao extract obtained by adding and immersing cacao beans in an organic solvent at a higher temperature and extracting the cacao beans. Here, the easily breakable capsule is a capsule of a strength such that the film bursts when pinched, exemplified by a seamless capsule. In addition, the natural cacao extract includes an alkaloid compound that not only expresses the intrinsic taste of tobacco but also provides flavor, body, and the true essence of tobacco. Moreover, the tobacco flavor enhancing liquid also includes a natural cacao extract along with other natural extracts or a combination of natural fragrance and synthetic fragrance. Typical examples thereof generally include: coffee, spices, herbs as natural extracts; absolute, resinoid, balsam, etc. as natural fragrances; and food fragrances as synthetic fragrances. Note that the film is preferably formed of a food additive.
  • In addition, as a means of achieving said object, the present invention provides a cigarette including said filter containing built-in capsule. Here, although this cigarette is preferably configured such that said filter containing built-in capsule is preliminarily incorporated in this filter part, it is not limited to this configuration and may be configured such that said filter containing built-in capsule is installed in the filter part of commercially available cigarettes. The present invention also provides a cigarette substitute by inserting said filter containing built-in capsule into the cartridge of an electronic cigarette, etc.
    • Effects of the Invention
  • According to the present invention, when smokers crush a capsule with their fingers, if necessary, the tobacco flavor enhancing liquid encapsulated in the capsule and including natural cacao extract oozes into the filter, thereby providing enhanced taste, aroma, richness, etc. specific to tobacco, which could not be supplemented by a casing source added to cut leaves alone. Consequently, it becomes unnecessary to select a high-tar and high-nicotine tobacco, effectively providing smokers with the same flavor even with a low-tar and low-nicotine tobacco. In addition, when the present invention is used in an electronic cigarette, etc., even such a tobacco not containing tar or nicotine will have the same taste as real tobacco. This effectively allows cigarette substitutes to exert this taste.

    •  EMBODIMENT OF THE INVENTION
  • Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
  • In the cigarette illustrated in FIG. 1, filter containing built-in capsule 1 of the present invention is incorporated in a standard paper-rolled cigarette. This paper-rolled cigarette includes cut leaf 2, rolling paper 3, filter 4, and tip paper 5.
  • With respect to cut leaf 2, different kinds of leaf tobacco are cut into fine pieces, to which fragrance is added in order to create a taste specific to tobacco when lit. The fragrance to be added to cut leaf 2 is a casing source with the main role of providing the intrinsic taste and aroma of leaf tobacco, along with a top flavor with the role of completing the taste and aroma of each brand. Sugar, cocoa, licorice, etc. are used as the casing source, while menthol, whisky, rum, fruit, vanilla, etc. are used as the top flavor.
  • Rolling paper 3 is paper for rolling up cut leaf 2 into a tube and slowly burning when lit. The material is a paper made of hemp and pulp.
  • Filter 4 plays a role in filtrating smoke and reducing the tar and nicotine in order to mellow the flavor. Examples of filter 4 include: a plain filter made of cellulose acetate; and a charcoal filter combining cellulose acetate with activated carbon (charcoal).
  • In order to connect cut leaf 2 to filter 4, part of tip paper 5 is superimposed and adhered on rolling paper 3 while rolled up in a tube. The material of tip paper 5 is a pulp mainly made of wood. In addition, microscopic vents are opened in tip paper 5, acting to adjust the amount of air passing therethrough in order to decrease the taste or reduce the tar and nicotine.
  • In filter containing built-in capsule 1 of the present invention, easily breakable capsule 6 is incorporated in filter 4. With respect to this capsule 6, film 7 bursts when pinched from outside tip paper 5, causing internal tobacco flavor enhancing liquid 8 to ooze into filter 4 and be absorbed therein.
  • In the present embodiment, a round seamless capsule is used as this capsule 6. The seamless capsule is produced by the falling-drop method, with the content liquid flowed from a double internal nozzle into the liquid, while a film liquid is flowed from an external nozzle into the liquid. Thereby, this 2-layer fluid is cut at predetermined intervals and added dropwise by interfacial tension, after which an external film liquid is gelated and formed into a capsule. Note that the size of capsule 6 is formed so as to have a diameter of approximately 0.5 to 7.0 mm. In addition, the number of capsules 6 incorporated in one filter 4 is not limited to one, but may be multiple.
  • The raw material of film 7 is preferably one that can safely touch the mouth. For example, various food additives and thickening agents can be used. Carrageenan and agar are suitable among various food additives and thickening agents as they tend to burst when formed into capsule 6 in a thickening agent. Carrageenan and agar are slightly soluble in heat and also preferable in terms of heat resistance.
  • Tobacco flavor enhancing liquid 8 that is encapsulated in film 7 is a liquid for enhancing the taste, aroma, richness, etc. specific to tobacco, with natural cacao extract being the main component. The reason for adopting natural cacao extract is that an alkaloid compound having the same structure as nicotine is often used as the casing source of tobacco. Exemplary alkaloid compounds include cacao with theobromine, as well as coffee and tea with caffeine. These are important natural extracts that not only express the intrinsic taste of tobacco but also provide flavor, body, and the true essence of tobacco.
  • Tobacco flavor enhancing liquid 8 uses natural cacao extract as the base, with the extract extracted by various methods such as the immersion-extraction method, reflux-extraction method, solvent extraction method, steam distillation method, counter current extraction method, and carbon dioxide extraction method. As a raw material for obtaining tobacco flavor enhancing liquid 8, cacao beans may be used alone or optionally blended with coffee beans. Exemplary cacao beans include species such as forastero, criollo, and trinitario, which are cacaos of the plant Sterculiaceae (Theobroma cacao L.), that are subjected to roasting. Coffee bean is the generic name of the Rubiaceae Coffea arabica plant, with the main cultivated varieties including arabica and robusta. While the coffee beans used in the present invention are not particularly limited in terms of their species, growing region, brand, quality, processing method, harvest time, etc., their compatibility with the film liquid of capsule 6 is important.
  • Tobacco flavor enhancing liquid 8 includes an extract (natural cacao extract) extracted from cacao beans as a single raw material or a raw material obtained by blending cacao beans and coffee beans. One example of the extraction method of this natural cacao extract is a method of adding an organic solvent to cacao beans as a single raw material or a raw material obtained by blending cacao beans and coffee beans, immersing them at a higher temperature for extraction, extracting the extract, and removing insoluble matter to obtain a solution. Subsequently, an organic solvent of an amount 3 to 20-fold the mass of the single or blended raw material is added and appropriately extracted after stirring for 15 to 120 minutes at 20 to 80° C. While the organic solvent used for extraction is not particularly limited, examples thereof include: alcohols such as methanol, ethanol, propanol, and propylene glycol; esters such as ethyl acetate and methyl acetate; ketones such as acetone and ethyl methyl ketone; hydrocarbons such as hexane and heptane; and edible oils and fats. Ethanol and edible oils and fats are particularly preferable among these in terms of safety.
  • With regard to tobacco flavor enhancing liquid 8, natural cacao extract obtained by said method may be used on its own or in combination with other raw materials. That is, natural cacao extract may be appropriately used in combination with a natural extract other than natural cacao extract, or a natural fragrance and synthetic fragrance. Exemplary natural extracts include: beans such as coffee; spices; spice extracts such as from herbs; tea; nuts; and foreign wines/liqueurs. Exemplary natural and synthetic fragrances include acetoacetic ester, acetophenone, anisic aldehyde, α-amyl cinnamaldehyde, methyl anthranilate, ionone, isoeugenol, isoamyl isovalerate, ethyl isovalerate, allyl isosulfocyanate, isothiocyanates, indole and its derivative, γ-undecalactone, esters, the mixture of 2-ethyl-3,5-dimethylpyrazine and 2-ethyl-3,6-dimethylpyrazine, ethyl vanillin, 2-ethyl pyrazine, 2-ethyl-3-methylpyrazine, 2-ethyl-5-methylpyrazine, ethers, eugenol, octanol, octanal, ethyl octanoate, isoamyl formate, geranyl formate, citronellyl formate, cinnamic acid, ethyl cinnamate, methyl cinnamate, ketones, geraniol, isoamyl acetate, ethyl acetate, geranyl acetate, cyclohexyl acetate, citronellyl acetate, cinnamyl acetate, terpinyl acetate, phenethyl acetate, butyl acetate, benzyl acetate, 1-menthyl acetate, linalyl acetate, methyl salicylate, allyl cyclohexylpropionate, citral, citronellal, citronellol, 1,8-cineole, fat acids, aliphatic higher alcohols, aliphatic higher aldehydes, aliphatic higher hydrocarbons, 2,3-dimethylpyrazine, 2,5-dimethylpyrazine, 2,6-dimethylpyrazine, cinnamyl alcohol, cinnamaldehyde, thioethers, thiols, decanal, decanol, ethyl decanoate, 5,6,7,8-tetrahydroquinoxaline, 2,3,5,6-tetramethylpyrazine, terpineol, limonene, pinene, myrcene, tapinoren, terpene hydrocarbons, 2,3,5-trimethylpyrazine, γ-nonalactone, vanillin, p-methylacetophenone, hydroxycitronellal, hydroxycitronellal dimethylacetal, piperonal, isoamyl phenylacetate, isobutyl phenylacetate, phenyl ethyl acetate, phenol ethers, phenols, furfural and derivatives thereof, propionic acid, isoamyl propionate, ethyl propanoate, benzyl propionate, hexanoic acid, allyl hexanoate, ethyl hexanoate, ethyl heptanoate, 1-perillaldehyde, benzyl alcohol, benzaldehyde, aromatic alcohols, aromatic aldehydes, d-borneol, maltol, N-methyl methyl anthranilate, 5-methylquinoxaline, 6-methylquinoline, methyl β-naphthyl ketone, 2-methylpyrazine, 2-methylbutanol, 3-methyl-2-butanol, 2-methylbutyraldehyde, d1-menthol, 1-menthol, butyric acid, isoamyl butyrate, ethyl butyrate, cyclohexyl butyrate, butyl butyrate, lactones, and linalool. Coffee, spices, herbs, esters, and pyrazines are particularly suitable in terms of flavor.
  • Here, the method of producing tobacco flavor enhancing liquid 8 will be described. First, the natural cacao extract obtained by said method is subjected to filter processing to separate the solid and liquid. Subsequently, the natural cacao extract in the liquid is removed and its quality is controlled. Once measured, natural extract and fragrance are measured and added. Subsequently, these are formulated and stirred, the specific gravity thereof is controlled, and the specific gravity, water content, and pH are controlled in order to form a capsule. Lastly, foreign matter is removed by filter processing, its quality is controlled, and measurement, subdivision, and filling are conducted to produce tobacco flavor enhancing liquid 8. Note that, as is clear from said raw material, tobacco flavor enhancing liquid 8 does not include any nicotine and tar components.
  • Capsule 6 has the above configuration. When smokers crush capsule 6 with their fingers while smoking, film 7 bursts, causing tobacco flavor enhancing liquid 8 to ooze into filter 4 and be absorbed therein. Consequently, the mainstream smoke passing through filter 4 mixes with tobacco flavor enhancing liquid 8 to reach the mouth of the smoker as the bittering component, thereby providing enhanced flavor aspects such as taste, aroma, and richness specific to tobacco, which cannot be supplemented by the casing source added to cut leaf 2.
  • As described above, according to the cigarette of the present embodiment, when tobacco flavor enhancing liquid 8 including natural cacao extract is encapsulated in capsule 6, and capsule 6 is incorporated in filter 4, fragrance can be imparted not only to the part of cut leaf 2 but also to tobacco flavor enhancing liquid 8 inside capsule 6. In addition, even if cut leaf 2 is lit during smoking, the fragrance does not vaporize right away, thereby minimizing the influence of heat. This has the effect of yielding a fresher flavor as the top flavor of tobacco.
  • In addition, when tobacco flavor enhancing liquid 8 including fragrance is formed into a capsule, tobacco flavor enhancing liquid 8 is sealed in film 7 and protected so as not to contact the air until smoking. Therefore, more highly-volatile fragrances can be used than when directly imparting fragrance to cut leaf 2, ensuring that the freshness of the aroma is maintained until smoking. In addition, food fragrances are used as the fragrance included in tobacco flavor enhancing liquid 8, with the raw material of film 7 formed from a food additive as in tobacco flavor enhancing liquid 8. This ensures that capsule 6 is safe in the event that it touches the mouth.
  • The cigarette illustrated in FIG. 1 is configured such that filter containing built-in capsule 1 of the present invention originally containing capsule 6 is incorporated in filter 4 of the paper-rolled cigarette. However, instead of this configuration, filter containing built-in capsule 1 of the present invention may be later installed in a commercially available cigarette.
  • The cigarette illustrated in FIG. 2 is smoked such that filter containing built-in capsule 1 of the present invention is installed outside the filter part of the paper-rolled cigarette to smoke. In this filter containing built-in capsule 1, filter 4 is inserted into case 9 made of a soft material, with easily breakable capsule 6 incorporated inside this filter 4. Note that the raw materials of filter 4, film 7 of capsule 6, and tobacco flavor enhancing liquid 8 are the same as mentioned above. As described above, the same effect as that mentioned above can also be achieved by installing filter containing built-in capsule 1 containing capsule 6 into commercially available paper-rolled cigarettes to smoke.
  • As mentioned above, although FIGS. 1 and 2 illustrate an example of applying filter containing built-in capsule 1 of the present invention to real tobacco, filter containing built-in capsule 1 of the present invention is applicable to cigarette substitutes such as in electronic cigarettes.
  • In the example illustrated in FIG. 3, filter containing built-in capsule 1 of the present invention is incorporated in a standard electronic cigarette. As illustrated in FIG. 3, this electronic cigarette includes body 10 and cartridge 11.
  • Body 10 comprises: battery 12 made of a lithium-ion battery; an atomizer 13 that evaporates liquid into a spray by heating a heating wire; electronic circuit 14 to sense the airflow in the body via an airflow sensor to drive battery 12; and indicator 15 including a red LED that lights when powered up. In addition, a refill filter is inserted into cartridge 11, and cartridge 11 is installed in body 10 such that it is detachable. In the present embodiment, filter containing built-in capsule 1 is inserted into this cartridge 11 and used.
  • Battery 12 is preliminarily charged for use by a charger in order to enable the use of this electronic cigarette. Moreover, filter containing built-in capsule 1 is pinched in order to crush capsule 6, and this is inserted into cartridge 11. At this time, tobacco flavor enhancing liquid 8 inside capsule 6 oozes into filter 4 and is absorbed therein.
  • Subsequently, this cartridge 11 is installed in body 10 and suctions suction port 16 at the end of cartridge 12 with the mouth. Then, an airflow sensor inside body 10 responds and power is supplied from battery 12 driven by electronic circuit 14 to atomizer 13. This power is used to heat a heating wire of atomizer 13 and evaporate tobacco flavor enhancing liquid 8 absorbed in filter 4 into a spray water vapor.
  • Moreover, vaporized water is suctioned via filter 4 from suction port 16 to the body and expelled via the mouth such that it looks like smoke. Consequently, the sensation of smoking real tobacco can be enjoyed. In addition, when battery 12 is driven and indicator 15 at the tip of the body lights red, it appears to be on fire, allowing a sensation similar to smoking real tobacco to be achieved.
  • As described above, in the present embodiment, when filter containing built-in capsule 1 is inserted into cartridge 12 of an electronic cigarette and used, it suctions water vapor with tobacco flavor enhancing liquid 8 evaporated therein. Further, flavor aspects such as taste, aroma, and richness having the same flavor as real tobacco can be tasted. Moreover, tobacco flavor enhancing liquid 8 does not include tar and nicotine components, providing a cigarette substitute that is harmless to the body.
  • Lastly, the effects of the present invention will be described based on tests conducted by the inventors.
  • <Test 1>
