Description
TECHNICAL FIELD
[0001] 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
[0002] 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.
[0003] 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.
[0004] 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.
[0005] 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.

BRIEF SUMMARY OF THE INVENTION
Problems to be Solved by the Invention
[0007] 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
[0008] 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.
[0009] 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
[0010] 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
[0018] Hereinafter, embodiments for carrying out the present
invention will be described with reference to the drawings.
[0019] 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.
[0020] 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.
[0021] 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.
[0022] 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).
[0023] 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.
[0024] 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.
[0025] 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.
[0026] 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.
[0027] 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.
[0028] 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.
[0029] 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.degree. 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.
[0030] 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, .alpha.-amyl cinnamaldehyde, methyl anthranilate, ionone,
isoeugenol, isoamyl isovalerate, ethyl isovalerate, allyl
isosulfocyanate, isothiocyanates, indole and its derivative,

butyrate, butyl butyrate, lactones, and linalool. Coffee, spices,
herbs, esters, and pyrazines are particularly suitable in terms of
flavor.
[0031] 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.
[0032] 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.
[0033] 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.
[0034] 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.
[0035] 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.
[0036] 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.
[0037] 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.
[0038] 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.
[0039] 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.
[0040] 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.
[0041] 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.
[0042] 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.
[0043] 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.
[0044] Lastly, the effects of the present invention will be
described based on tests conducted by the inventors.
[0045] <Test 1>
[0046] Objective: a test for determining the base raw material of
the tobacco flavor enhancing liquid
[0047] Method: The three kinds raw materials that were most
effective in terms of testing and research results among many raw
materials were selected, among which a test for determining the
base raw material was conducted. The three kinds of raw materials
were cacao beans, coffee beans, and tea leaves, each of which
contained caffeine. These raw materials were immersed at a higher
temperature and extracted under similar conditions in order to
prepare solutions A, B, and C, which were formed into a seamless
capsule by the falling-drop method, after which each capsule was
incorporated in the tobacco filter (tar: 1 mg, nicotine: 0.1 mg)
produced by Company X. Moreover, the subjects were asked to taste
the flavor of cigarettes lit after crushing the capsule, in
addition to tasting the flavor of cigarettes (tar: 1 mg, nicotine:
0.1 mg) produced by Company X not incorporating the capsule. FIG. 4
summarizes the impressions of the subjects who compared both
flavors. Note that the subjects were 100 general smokers.
[0048] Results: FIG. 4 indicates that while each of A, B, and C
enhanced the flavor of the tobacco, A was the most appropriate with
regard to the object of Test 1. In A, cacao beans were the base raw
material.
[0049] <Test 2>
[0050] Objective: a test for determining the blending ratio of
natural cacao extract
[0051] Method: Based on the results of Test 1, cacao beans were
selected as the base raw material, and three kinds of solutions D,
E, and F with different blending ratios of natural cacao extract
were prepared. The preparation method was the same as that in Test
1, with the following tables indicating the compositions of the
respective solutions.

[0052] Three kinds of solutions D, E, and F were formed into a
seamless capsule by the falling-drop method, with each capsule
incorporated in the tobacco filter (tar: 1 mg, nicotine: 0.1 mg)
produced by Company X. Moreover, the subjects were asked to taste
the flavor of cigarettes lit after crushing the capsule, in
addition to tasting the flavor of cigarettes (tar: 1 mg, nicotine:
0.1 mg) produced by Company X not incorporating the capsule. FIG. 5
summarizes the impressions of the subjects who compared both
flavors. Note that the subjects were 100 general smokers.
[0053] Results: FIG. 5 indicates that while each of D, E, and F
exerted the effect of enhancing the flavor of tobacco, F was the
most appropriate with regard to the object of Test 2. In F, the
blending ratio of the natural cacao extract was 75%.
[0054] <Test 3>
[0055] Objective: a test to get smokers of cigarettes produced by
Company X to compare the taste
[0056] Method: Based on the results of Test 2, solution F was
formed into a seamless capsule by the falling-drop method, and each
capsule was incorporated in the tobacco filter (tar: 1 mg,
nicotine: 0.1 mg) produced by Company X. Moreover, the subjects
were asked to taste the flavor of cigarettes lit after crushing the
capsule, in addition to tasting the flavor of cigarettes (tar: 1
mg, nicotine: 0.1 mg) produced by Company X. FIG. 6 summarizes the
impressions of the subjects who compared both flavors. Note that
the subjects were 10 smokers different from the smokers of tests 1,
2. The 10 smokers usually smoke cigarettes (tar: 1 mg, nicotine:
0.1 mg) produced by Company X.
[0057] Results: FIG. 6 indicates the results. In addition, other
impressions of the subjects were as follows.
[0058] Subject 1: It was rich and tasted good.
[0059] Subject 2: It was flavorful.
[0060] Subject 3: It was rich and tasted good.
[0061] Subject 4: It was a little strong, but I can smoke this
cigarette.
[0062] Subject 5: It was strong, but the aroma of the smoke was
good.
[0063] Subject 6: I felt the sensation of smoking tobacco for the
first time in many years.
[0064] Subject 7: The tar was strong, but it tasted good.
[0065] Subject 8: The aftertaste was not that of a low-tar
tobacco.
[0066] Subject 9: It was strong, so I was not able to finish
smoking it.
[0067] Subject 10: The tar was strong.
[0068] The above results clearly proved that solution F could exert
the effect of enhancing the flavor of the tobacco.
[0069] <Test 4>
[0070] Objective: a test to get smokers of cigarettes other than
cigarettes produced by Company X to compare the taste
[0071] Method: Based on the results of test 2, solution F was
formed into a seamless capsule by the falling-drop method, and each
capsule was incorporated in the tobacco filter (tar: 1 mg,
nicotine: 0.1 mg) produced by Company X. Moreover, the subjects
were asked to taste the flavor of cigarettes lit after crushing the
capsule, in addition to tasting the flavor of cigarettes (tar: 1
mg, nicotine: 0.1 mg) produced by Company X not incorporating the
capsule. FIG. 7 summarizes the impressions of the subjects who
compared both flavors. Note that subjects were 10 smokers different
from the smokers of tests 1, 2, 3. The 10 smokers usually do not
smoke cigarettes (tar: 1 mg, nicotine: 0.1 mg) produced by Company
X but smoke cigarettes of other makers.
[0072] Results: FIG. 7 indicates the results. In addition, other
impressions of the subjects were as follows.
[0073] Subject 11: It was a tasty cigarette that I could smoke
normally. . . . smoker of 8 mg tar per day
[0074] Subject 12: I could smoke it normally. . . . smoker of 6 mg
tar per day
[0075] Subject 13: It was strong and worth smoking. . . . smoker of
6 mg tar per day
[0076] Subject 14: I found it to be a strong cigarette because I
usually smoke menthol. . . . smoker of 8 mg tar per day
[0077] Subject 15: I felt that it was strong in my throat. . . .
smoker of 1 mg tar per day
[0078] Subject 16: It tasted like a mild cigarette. . . . smoker of
10 mg tar per day
[0079] Subject 17: The aroma was good but the tar was a little
lacking. . . . smoker of 12 mg tar per day
[0080] Subject 18: As for the smoking flavor, the flavor was good
and there was little aftertaste. . . . smoker of 6 mg tar per
day
[0081] Subject 19: I like a stronger cigarette. . . . smoker of 9
mg tar per day
[0082] Subject 20: The aftertaste in the mouth was cleaner than
other cigarettes. . . . smoker of 10 mg tar per day
[0083] The above results clearly proved that in cigarettes
containing 1 mg of tar along with 0.1 mg of nicotine, the use of
solution F enabled the effective enhancement of the flavor of
cigarettes.
