fingers caused by smoking and solve a tipping paper curl issue and
a tipping paper surface contamination problem which occur due to
application of the printing process.
[0021] In addition, since the fragrance material is included in a
carrier and printed, it is possible to reduce the amount of
fragrance that disseminates during simple storage of smoking
articles and increase the amount of fragrance that disseminates
during smoking.
[0022] Further, since ethanol is used as a solvent for ink in a
fragrance carrier printing process, and the extent to which an ink
is dried and the extent to which a curl occurs in the tipping paper
are secured at an equivalent level compared to a case in which the
fragrance carrier printing process is not applied, it is possible
to also secure the workability of printing the fragrance
carrier.

the smoking article 100 illustrated in FIG. 1, a smoking material
portion 120 is disposed upstream or in an upstream direction from a
filter portion 110.
[0033] Further, in the specification, a case in which the smoking
article 100 is a combustion-type cigarette is described as an
example. However, the present invention is not limited thereto, and
the smoking article 100 may also be a heating-type cigarette or the
like that is used together with an aerosol generation device (not
illustrated) such as an electronic cigarette device.
[0034] FIG. 1 is a view illustrating a smoking article to which a
tipping paper is applied according to an embodiment of the present
invention.
[0035] Referring to FIG. 1, the smoking article 100 may include the
filter portion 110 wrapped by a filter wrapper 110a, the smoking
material portion 120 wrapped by a smoking material wrapper 120a,
and a tipping paper 130 configured to combine the filter portion
110 and the smoking material portion 120.
[0036] The filter portion 110 may be disposed downstream from the
smoking material portion 120, and an aerosol material generated in
the smoking material portion 120 may pass through the filter
portion 110 before being inhaled by the user.
[0037] The filter portion 110 may be formed of various materials.
For example, the filter portion 110 may be a cellulose acetate
filter.
[0038] In some embodiments, the filter portion 110 may be a
cellulose acetate filter without being scented with a fragrance
material, but the present invention is not limited thereto. The
filter portion 110 may also be a transfer jet nozzle system (TJNS)
filter scented with a fragrance material.
[0039] In some embodiments, the filter portion 110 may be a tubular
structure including a hollow formed therein. The filter portion 110
may also be manufactured by inserting structures such as films or
tubes formed of the same or different materials (for example, into
the hollow).
[0040] Moreover, a hardness of the filter portion 110 may be
adjusted by controlling the content of plasticizer during
manufacture of the filter portion 110. Triacetin may be applied as
a plasticizer and included at a weight ratio in a range of about 5
to 15% with respect to the total weight of the filter portion 110,
but the type and content of the plasticizer are not limited thereto
and may be properly controlled as necessary.
[0041] The filter portion 110 of the present embodiment is
illustrated as a mono filter formed of a single filter, but the
embodiment is not limited thereto. For example, the filter portion
110 may, of course, be provided as a dual filter, which includes
two acetate filters, a triple filter, or the like in order to
increase filter efficiency.
[0042] Further, a capsule (not illustrated) may be included inside
the filter portion 110. The capsule may have a structure in which a
liquid including a fragrance and filled therein is wrapped by a
film. For example, the capsule may have a spherical or cylindrical
shape. A diameter of the capsule may be in a range of about 2.6 mm
to 3.5 mm, but is not limited thereto. The diameter of the capsule
may vary according to the standard of the smoking article 100.
[0043] Materials forming the film of the capsule may be a natural
material, starch, and/or a gellant. For example, a film made of a
natural material may be composed of agar, pectin, sodium alginate,
glycerin, and the like. Gellan gum or gelatin may be used as the
gellant. Also, a gelation auxiliary agent may be further used as a
material forming the film of the capsule. Here, as the gelation
auxiliary agent, for example, calcium chloride may be used. Also, a
plasticizer may be further used as a material forming the film of
the capsule. Here, as the plasticizer, glycerin and/or sorbitol may
be used. Also, a coloring agent may be used as a material forming
the film of the capsule.
[0044] In some embodiments, as a solvent for the fragrance included
in the liquid filled in the capsule, for example, a medium chain
fatty acid triglyceride (MCTG) may be used. The liquid may also
include other additives such as coloring, an emulsifier, and a
thickener.
[0045] A fragrance such as menthol and an essential oil of plants
may be included in the liquid filled in the capsule, but the
present invention is not limited thereto.
[0046] The filter portion 110 may be wrapped by the filter wrapper
110a. In some embodiments, the filter wrapper 110a may be produced
using grease-resistant wrapping paper in order to prevent a liquid
filled in the capsule in the filter portion 110 passing through the
filter wrapper 110a and being released to the outside of the
capsule due to the smoker crushing the capsule. In some
embodiments, an aluminum foil may be further included at an inner
surface of the filter wrapper 110a.
[0047] The filter portion 110 is disposed downstream of the smoking
material portion 120 and serves as a filter through which an
aerosol material generated in the smoking material portion 120
passes before being inhaled by the user.
[0048] The smoking material portion 120 may contain an
aerosol-generating material. For example, the smoking material
portion 120 may include tobacco strands. The smoking material
portion 120 may have the form of a longitudinally extending rod
which may have various lengths, circumferences, and diameters.
[0049] In some embodiments, the aerosol-generating material may
include at least one of glycerin, propylene glycol, ethylene
glycol, dipropylene glycol, diethylene glycol, triethylene glycol,
tetraethylene glycol, and oleyl alcohol.
[0050] In some embodiments, the smoking material portion 120 may
also include other additives such as a flavoring agent, a wetting
agent, and/or an acetate compound. For example, the flavoring agent
may include licorice, saccharose, fructose syrup, isosweet, cocoa,
lavender, cinnamon, cardamom, celery, fenugreek, cascarilla, white
sandalwood, bergamot, geranium, honey essence, rose oil, vanilla,
lemon oil, orange oil, mint oil, cinnamon, caraway, cognac,
jasmine, chamomile, menthol, cinnamon, ylang-ylang, sage,
spearmint, ginger, cilantro, coffee, or the like. Also, the wetting
agent may include glycerin, propylene glycol, or the like.
[0051] In some embodiments, the smoking material portion 120 may
include a reconstituted tobacco material which is formed in the
shape of pieces of rods or the like, by grinding tobacco raw
materials, mixing a solvent and various additives with the ground
tobacco raw materials to make a tobacco slurry, drying the tobacco
slurry to form a tobacco sheet, and processing the tobacco sheet.
For example, the smoking material portion 120 may include a
plurality of tobacco material strands, and each strand may have a
length in a range of about 10 mm to 14 mm (for example, 12 mm), a
width in a range of about 0.8 mm to 1.2 mm (for example, 1 mm), and
a thickness in a range of about 0.08 mm to 0.12 mm (for example,
0.1 mm), but the present invention is not limited thereto.
[0052] Since the smoking material portion 120 includes a plurality
of strand materials formed by processing a wide tobacco sheet, a
density of tobacco materials filled in the smoking material portion
120 may increase. Accordingly, the amount of aerosol generated may
be increased, and smoking taste or feature of the smoking material
portion 120 may be improved.
[0053] The smoking material portion 120 may be wrapped by the
smoking material wrapper 120a.
[0054] In some embodiments, the smoking material wrapper 120a may
include a filler. Accordingly, an opacity of the smoking material
wrapper 120a may be increased, porosity may be imparted to the
smoking material wrapper 120a, smoothness and ash integrity of the
cigarette paper may be improved, and whiteness of the cigarette
paper may be increased. Materials such as calcium carbonate,
titanium dioxide, and magnesium oxide may be used as the filler,
but the present invention is not limited thereto.
[0055] Also, although not illustrated, the smoking material wrapper
120a may have a double wrapping paper structure. Specifically, the
smoking material wrapper 120a may include an inner wrapper (not
illustrated) that comes in contact with the smoking material
portion 120 and surrounds the smoking material portion 120 and an
outer wrapper that comes in contact with the inner wrapper and
surrounds an outer portion of the inner wrapper.
[0056] The filter portion 110 wrapped by the filter wrapper 110a
and the smoking material portion 120 wrapped by the smoking
material wrapper 120a may be wrapped together by the tipping paper
130. That is, the tipping paper 130 may wrap around at least a
portion (for example, a partial downstream region) of the smoking
material wrapper 120a and an outer boundary of the filter wrapper
110a. In other words, at least a portion of the smoking material
portion 120 and the filter portion 110 may be further wrapped by
the tipping paper 130 and physically combined.
[0057] In some embodiments, the tipping paper 130 may be produced
using nonporous wrapping paper that is not treated to be
grease-resistant, but the present invention is not limited
thereto.
[0058] The tipping paper 130 may be coated with a sweetener such as
sucralose and citric acid. Also, a predetermined material may be
added into the tipping paper 130. Silicone may be an example of the
predetermined material, but the predetermined material is not
limited thereto. For example, silicone has characteristics such as
being heat-resistant (i.e., not changing much of its
characteristics due to temperature), being oxidation-resistant
(i.e., not being oxidized), being resistant to various chemicals,
being water-repellent, and being electrically insulated. However,
any material other than silicone may be applied or coated on the
tipping paper 130 as long as the material has the above-described
or similar characteristics.
[0059] The tipping paper 130 may prevent a phenomenon in which the
filter portion 110 is combusted. For example, in a case in which
the smoking material portion 120 is combusted up to a portion
thereof adjacent to the filter portion 110, there is a possibility
that the filter portion 110 may also be combusted. Even such a
case, since the tipping paper 130 includes an incombustible
material, the phenomenon in which the filter portion 110 is
combusted may be prevented.
[0060] During the manufacture of the smoking material wrapper 120a,
various attempts have been made as described above, such as
including a filler in the smoking material wrapper 120a using
various compositions and methods, forming the double wrapping paper
structure in the smoking material wrapper 120a, or applying a
water-soluble fragrance carrier that includes a fragrance to the
smoking material wrapper 120a, in order to reduce a tobacco smell
caused by smoke generated during smoking. However, apart from the
sidestream smoke reduction effect or the like of the various
attempts, since the tipping paper 130 is in direct contact with
fingers of a smoker when the smoker smokes, instead of the smoking
material wrapper 120a, one or more embodiments for reducing a
tobacco smell on fingers that may be directly applied to the
tipping paper 130, instead of the smoking material wrapper 120a, to
effectively reduce the tobacco smell on the fingers.
[0061] Thus, the tipping paper 130 of the present invention
includes a fragrance carrier that includes a fragrance material for
masking a tobacco smell and a carrier material including the
fragrance material. The fragrance carrier may be disposed onto the
tipping paper through a process of printing the fragrance carrier
on the tipping paper by using a fragrance carrier ink including
ethanol, the fragrance material, and the carrier material.
[0062] The fragrance carrier ink may be produced by sequentially
adding the carrier material, the fragrance material, and a binder
to the ethanol and stirring solutions obtained thereof.
Specifically, the fragrance carrier ink may be produced by: i)
adding the carrier material to ethanol and stirring a solution
obtained thereof for about 30 minutes to 60 minutes; ii) adding the
fragrance material to the solution in which the carrier material is
added to ethanol and stirring a solution obtained thereof for about
15 minutes to 45 minutes; and iii) adding the binder to the
solution in which the carrier material and the fragrance material
are added to ethanol and stirring a solution obtained thereof for
about 15 minutes to 45 minutes.
[0063] When the fragrance carrier ink includes microcapsules, which
will be described below, the method of producing the fragrance
carrier ink may further include, after the step iii), a step of iv)
adding microcapsules to the solution in which the carrier material,
the fragrance material, and the binder are added to ethanol and
stirring a solution obtained thereof for about 15 minutes to 45
minutes.
[0064] The fragrance carrier printing process may be performed by
mixing the fragrance carrier with an ink used in an overprint
varnish (OPV) process that is performed on the tipping paper.
However, preferably, in order to maximize the amount of carried
fragrance that is delivered to the tipping paper, the fragrance
carrier printing process may be performed as a printing process
separate from the OPV process after the OPV process.
[0065] In some embodiments, the fragrance carrier ink may further
include a binder and/or microcapsules. The binder and microcapsules
will be described in detail below.
[0066] The carrier material in the present invention is a material
that is soluble in ethanol, but not soluble in water, isopropyl
alcohol, and the like. For example, the carrier material may be
2-hydroxypropyl-.beta.-cyclodextrin.
[0067] This is because, in reality, a method of applying a
water-soluble fragrance carrier material (for example,
.beta.-cyclodextrin), which includes a fragrance material, to the
above-described smoking material wrapper 120a cannot be applied as
is to the tipping paper 130 that requires printing and drying
processes. Specifically, when applying the water-soluble fragrance
carrier method to the tipping paper 130, water should be used as a
solvent for ink. In this case, the surface energy of the ink may be
increased to about 70 mN/m to 75 mN/m, and thus, a difficulty may
occur in the drying process after the ink is printed on the tipping
paper 130, and problems such as contamination of the tipping paper
and a phenomenon in which the ink peels off due to weakening of a
binding force between the printed ink and the tipping paper may
occur. Further, in a case in which a drying temperature or drying
time is increased to dry the ink of which the surface energy is
increased, a curl of the tipping paper is increased. Unlike the
above, in a case in which a fragrance material is printed on the
tipping paper without applying the carrier method, due to a
characteristic of the tipping paper being disposed at an outermost
portion of the smoking article, the fragrance material may be lost
to the outside of the smoking article during a period in which the
smoking article is stored, or the tipping paper may be discolored
according to storage conditions such as light exposure and humidity
level.
[0068] On the contrary, in a case in which a polymer material, such
as 2-hydroxypropyl-.beta.-cyclodextrin, that is soluble in ethanol
and includes a hydrophobic fragrance material, is applied as the
carrier material that is applied to the tipping paper as in the
present invention, ethanol may be used as a solvent for ink, and
thus, an ink having a surface energy of about 20 mN/m to 50 mN/m
may be used. Accordingly, it is possible to apply the printing and
drying processes of the tipping paper, and not only the workability
of producing smoking articles, but also the stability of storing
the smoking articles may be secured because there is no
discoloration issue.
[0069] In addition, the fragrance material included in the carrier
material may be disseminated or diffused outside the tipping paper
130 (that is, outside the smoking article 100) in response to
moisture, saliva, or friction, and the disseminated fragrance
material may be spread to the fingers of the smoker gripping the
tipping paper portion and serve to mask the tobacco smell on the
fingers.
[0070] Further, since the fragrance material remains in the carrier
material and is not disseminated before moisture or saliva from the
smoker is in contact with the tipping paper or friction is
transmitted to the tipping paper (for example, by the smoker
gripping or rubbing the tipping paper), a problem in that a scent
is lost over the storage period or a problem in that a fragrance is
unnecessarily disseminated while the smoker is not using the
smoking article may be solved.
[0071] The fragrance material in the carrier material may include
one or more materials of vanillin and ethyl vanillin.
[0072] As will be described below with reference to Table 7 and
Table 8, a sum of weight ratios of the vanillin and ethyl vanillin
in consideration of the tipping paper discoloration issue may be
greater than 0% and lower than or equal to 50% with respect to the
total weight of the fragrance material. Preferably, the weight
ratio of vanillin with respect to the total weight of the fragrance
material is greater than 0% and lower than or equal to 30%, and the
weight ratio of ethyl vanillin with respect to the total weight of
the fragrance material is greater than 0% and lower than or equal
to 20%. More preferably, the weight ratio of the vanillin with
respect to the total weight of the fragrance material is in a range
of about 15% to 25%, and the weight ratio of the ethyl vanillin
with respect to the total weight of the fragrance material is in a
range of about 5% to 15%.
[0073] The fragrance material may include various components other
than the vanillin and ethyl vanillin. Table 1 shows a list of
components for the fragrance material which were confirmed to
maximize the effect of reducing the tobacco smell on fingers.

[0074] In some embodiments, the fragrance material may have a
component ratio in the order of rosemary
oil>vanillin>fermented ethyl alcohol>lavandin oil>ethyl
vanillin>eucalyptol. A content ratio of the vanillin and
eucalyptol contained in the fragrance material may be in a range of
about 2.5:1 to 3.5:1 (preferably, about 3:1), and a content ratio
of the ethyl vanillin and lavandin oil in the fragrance material
may be in a range of about 0.5:1 to 1.5:1 (preferably, about 1:1),
but the present invention is not limited thereto.
[0075] When the fragrance carrier ink contains more fragrance
material than necessary, a problem may occur in that a fragrance is
spread to other tipping paper, to which the fragrance should not be
applied. In addition to being spread to the tipping paper of the
present invention during a cigarette mass production process, and a
problem may occur in that the tipping paper of the present
invention is discolored while being stored after being
produced.
[0076] To address such problems, a weight ratio of the fragrance
material with respect to the total weight of the fragrance carrier
ink may be greater than 0% and lower than or equal to about 3%, and
a weight ratio of the carrier material with respect to the total
weight of the fragrance carrier ink may be greater than 0% and
lower than or equal to about 30%. Preferably, the weight ratio of
the fragrance material with respect to the total weight of the
fragrance carrier ink may be greater than 0% and lower than or
equal to about 1.5%, and the weight ratio of the carrier material
with respect to the total weight of the fragrance carrier ink may
be greater than 0% and lower than or equal to about 15%. More
preferably, the weight ratio of the fragrance material with respect
to the total weight of the fragrance carrier ink may be in a range
of about 0.4% to 1.3%, and the weight ratio of the carrier material
with respect to the total weight of the fragrance carrier ink may
be in a range of about 5% to 10%.
[0077] The binder that may be included in the fragrance carrier ink
may be an acrylic and starch-based polymer that is soluble in
ethanol. When the binder is included in the fragrance carrier ink,
the residual amount of the fragrance material, which is included in
the fragrance carrier, in the tipping paper may be increased. That
is, the fragrance material or fragrance carrier that may be lost
over the storage period of the smoking article after the smoking
article is produced may be better preserved in the tipping paper by
the binder.
[0078] Moreover, for the binder to also secure the workability of
printing while serving to preserve the fragrance material, an
appropriate viscosity is required for the binder. To this end, the
binder may be a polymer material that has a molecular weight in a
range of about 1,000 to 30,000 and a glass transition temperature
in a range of about 50.degree. C. to 100.degree. C. Preferably, the
binder may be a polymer material that has a molecular weight in a
range of about 3,000 to 20,000 and a glass transition temperature
in a range of about 60.degree. C. to 90.degree. C. This is because,
when the viscosity of the binder is too low, the ink may flow down,
and when the viscosity of the binder is too high, the ink may
become stiff, which may degrade the workability and performance of
the binder itself.
[0079] Also, as will be described below with reference to Table 4,
a fragrance retaining property tends to increase with an increase
in an amount of applied binder, but in a case in which too much
binder is applied, the curl of the tipping paper may be increased,
and there may be difficulty in producing the smoking article.
[0080] To address such a difficulty, a weight ratio of the binder
with respect to the total weight of the fragrance carrier ink may
be greater than 0% and lower than or equal to about 15%.
Preferably, the weight ratio of the binder with respect to the
total weight of the fragrance carrier ink is in a range of about 5%
to 10%.
[0081] The microcapsules that may be included in the fragrance
carrier ink may each include polyvinyl alcohol (PVA), a fragrance,
and a cross-linking agent. Specifically, a core of each
microcapsule may be an ethanol-based fragrance, a shell of each
microcapsule may be PVA, and sodium sulfate (Na.sub.2SO.sub.4) may
be used as the cross-linking agent. The fragrance may be an
ethanol-based fragrance. The microcapsules may each have a diameter
in a range of about 1.5 .mu.m to 5.0 .mu.m.
[0082] In some embodiments, the fragrance may also have the same
composition as the fragrance material included in the fragrance
carrier material.
[0083] In some embodiments, a content ratio of the PVA and the
fragrance in each microcapsule may be in a range of about 1:3 to
1:7. Preferably, the content ratio of the PVA and the fragrance in
each microcapsule is about 1:5. For example, each microcapsule may
be produced by stirring about 5% PVA, about 25% fragrance, and
about 1.5% cross-linking agent.
[0084] In some embodiments, a weight ratio of the microcapsules
with respect to the total weight of the fragrance carrier ink may
be greater than 0% and lower than or equal to about 25%, and
preferably, may be in a range of about 5% to 20%. As such, it is
possible to address a problem where a fragrance is excessively
disseminated before smoking due to breakage of the microcapsules
and/or a problem where the surface of the tipping paper is
contaminated by the shells of the microcapsules and roughens, which
may occur when the fragrance carrier ink contains an excessive
amount of microcapsules.
[0085] In some embodiments, the weight ratio of the binder with
respect to the total weight of the fragrance carrier ink may be in
a range of about 5% to 10%, and the weight ratio of the
microcapsules with respect to the total weight of the fragrance
carrier ink may be in a range of about 5% to 20%. Preferably, the
weight ratios of the binder and the microcapsules with respect to
the total weight of the fragrance carrier ink is about 5%.
[0086] The microcapsules may be produced by: i) stirring an
ethanol-based fragrance and PVA at room temperature for about 15
minutes to 45 minutes; ii) adding a cross-linking agent, at a level
of about 30% with respect to the PVA, to a solution in which the
ethanol-based fragrance and the PVA are stirred and stirring a
solution obtained thereof at a temperature which is higher than or
equal to about 60.degree. C. and lower than or equal to about
100.degree. C. for about 5 hours to 10 hours; and iii) cooling the
solution in which the ethanol-based fragrance, the PVA, and the
cross-linking agent are stirred, at room temperature for about 30
minutes to 2 hours.
[0087] Hereinafter, the embodiments of the present invention and
the advantageous effects thereto will be described in more detail
using examples and comparative examples. However, the examples are
merely for describing the present invention in more detail, and the
scope of the present invention is not limited by these
examples.
Comparative Example 1
[0088] An OPV printing process was performed on a tipping paper
material produced for testing of examples, which had undergone and
completed a process of printing a first design and a process of
printing a second design different from the first design, and then
a drying process was performed at a drying speed of about 150
m/min.
Comparative Example 2
[0089] A printing process using an ink including a water-soluble
fragrance carrier including a fragrance material was performed on
the tipping paper material of Comparative Example 1, which had
undergone and completed the OPV printing process and the drying
process, and then a drying process was performed at a drying speed
of about 150 m/min. In the water-soluble fragrance carrier printing
process, a fragrance carrier ink, for which water was used as a
solvent and which contained about 1.25% fragrance material(s) of
Table 1 above, about 9% .beta.-cyclodextrin, and about 5%
water-soluble binder, was used.
Comparative Example 3
[0090] A drying process was performed at a drying speed of about 10
m/min on the tipping paper material of Comparative Example 2, which
had undergone and completed the printing process using the ink
including the water-soluble fragrance carrier.
Example 1
[0091] The fragrance carrier printing process of the present
invention was performed on the tipping paper material of
Comparative Example 1, which had undergone and completed the OPV
printing process and the drying process, and then a drying process
was performed at a drying speed of about 150 m/min. In the
fragrance carrier printing process, a fragrance carrier ink, for
which ethanol was used as a solvent and which contained about 1.25%
fragrance material(s) of Table 1 above, about 9%
2-hydroxypropyl-.beta.-cyclodextrin, and about 5% binder, was
used.
Experimental Example 1: Evaluation of Drying and Curl
Characteristics of Tipping Paper after Ink is Printed on Tipping
Paper
[0092] In order to confirm drying and curl characteristics of the
tipping paper produced according to the examples of the present
invention after an ink is printed on the tipping paper, the surface
energy of ink applied to printing, the extent to which the
fragrance carrier is dissolved, the extent to which the ink is
dried, and a curl of the tipping paper were analyzed for each of
the example and comparative examples, and results thereof are shown
in Table 2 below.

Example 3 soluble fragrance carrier(1.25%) + water-soluble

[0093] As shown in Table 2, the extent to which the fragrance
carrier is dissolved was good in all of Example 1 and Comparative
Examples 2 and 3. However, in the tipping paper of Comparative
Example 2 on which the water-soluble fragrance carrier was printed,
it was confirmed that the ink was not completely dried after the
printing and drying processes. This is due to the surface energy of
the ink having a high value of 72.4 mN/m, which is due to using
water as the solvent for the ink when printing the water-soluble
fragrance carrier. In Comparative Example 3 in which the drying
speed was lowered to 10 m/min to completely dry the ink for which
water was used as the solvent, the extent to which the ink is dried
was good, but a curl of the tipping paper occurred at a high
numerical value of about 12 mm. Thus, the tipping paper of
Comparative Example 3 was found to be not applicable to a cigarette
mass production process.
[0094] On the other hand, regarding the tipping paper of Example 1,
in which ethanol was used as the solvent for the ink and to which
the fragrance carrier and binder were applied, the extent to which
the ink is dried was good and a curl of the tipping paper did not
show a statistically significant difference from the numerical
value thereof according to Comparative Example 1 in which the
fragrance carrier printing process was not applied. Thus, it was
confirmed that there was no problem at all in applying the tipping
paper of Example 1 to a cigarette mass production process.
Example 2
[0095] A tipping paper was removed from a cigarette produced for
testing, and a material portion and a filter portion were
separated. A smoking article was produced by combining the
separated material portion and filter portion using a tipping paper
having a porosity of about 100 CU that was produced by applying the
OPV process and the fragrance carrier printing process using an
ethanol-based fragrance carrier ink containing 0.4% fragrance
material.
Example 3
[0096] A smoking article was produced in the same way as in Example
2 except that the ethanol-based fragrance carrier ink contained
0.7% fragrance material.
Example 4
[0097] A smoking article was produced in the same way as in Example
2 except that the ethanol-based fragrance carrier ink contained
1.25% fragrance material.
Example 5
[0098] A smoking article was produced in the same way as in Example
2 except that the ethanol-based fragrance carrier ink contained
1.5% fragrance material.
Comparative Example 4
[0099] A smoking article was produced in the same way as in Example
2 except that, unlike in Examples 2 to 5, the fragrance printing
process was performed by stirring the fragrance material in the ink
without including the fragrance material in a carrier.
Experimental Example 2: Evaluation of Index Materials of Tipping
Paper for Reducing Tobacco Smell on Fingers--No Binder Applied
[0100] In order to measure the effect of reducing a tobacco smell
on fingers when smoking cigarettes according to the examples and
the comparative example, changes in contents of vanillin and ethyl
vanillin in smoke collected from the tipping paper were analyzed,
and results thereof are shown in Table 3 below.
[0101] All of the smoking articles according to the examples and
the comparative example were smoked two weeks after being produced.
Smoking conditions were set as follows: a puff volume of 55 ml, a
puff time of 2 seconds, a puff cycle of 20 seconds, and a puff
number of 12. The analysis of contents of vanillin and ethyl
vanillin was performed by gas chromatography (GC) analysis of smoke
collected by wrapping a Cambridge filter pad (CFP) around the
tipping paper 130.

[0102] As shown in Table 3, vanillin and ethyl vanillin components
were detected in all of the examples. Therefore, it was confirmed
that the detected vanillin and ethyl vanillin components may serve
to mask a tobacco smell on fingers by coming in contact with the
fingers. In addition, from the results of analysis of Example 4 and
Comparative Example 4, it can be confirmed that, while the contents
of the fragrance material in the ink were the same, more vanillin
and ethyl vanillin components were detected in the case in which
fragrance carrier printing was performed by including the fragrance
material in the carrier material (Example 4) as compared to the
case in which fragrance printing was performed without including
the fragrance material in a carrier (Comparative Example 4).
[0103] Further, from the results of analysis of Examples 2 to 5, it
was found that the amounts of vanillin and ethyl vanillin
components in the tipping paper increased with an increase in the
content of the fragrance material in the fragrance carrier ink.
However, in the case of Example 5 in which the content of the
fragrance material included in a carrier was 1.5%, a problem
occurred in that a fragrance spread to other tipping paper, to
which the fragrance should not be applied, in addition to being
spread to the tipping paper of the present invention during a
cigarette mass production process. It was found that, in Example 4
in which the content of the fragrance material included in a
carrier was 1.25%, the effect of reducing a tobacco smell on
fingers caused by smoking was excellent and the tipping paper could
be applied to cigarette mass production without any problems.
Example 6
[0104] A smoking article was produced in the same way as in Example
4 described above with reference to Table 3, except that the
ethanol-based fragrance carrier ink contained 1.0% binder. A
polymer material having a molecular weight of about 18,000 and a
glass transition temperature of about 80.degree. C. was used as the
binder.
Example 7
[0105] A smoking article was produced in the same way as in Example
6 except that the ethanol-based fragrance carrier ink contained
3.0% binder.
Example 8
[0106] A smoking article was produced in the same way as in Example
6 except that the ethanol-based fragrance carrier ink contained
5.0% binder.
Example 9
[0107] A smoking article was produced in the same way as in Example
6 except that the ethanol-based fragrance carrier ink contained
15.0% binder.
Experimental Example 3: Evaluation of Index Materials of Tipping

[0108] In order to measure the effect of reducing a tobacco smell
on fingers when smoking cigarettes according to the examples and
the comparative example, changes in contents of vanillin and ethyl
vanillin in smoke were collected from the tipping paper and
analyzed. The results of the analysis are shown in Table 4

[0109] As shown in Table 4, it was found that the amounts of
vanillin and ethyl vanillin components in the tipping paper
increased with an increase in the content of the binder in the
fragrance carrier ink. However, in the case of Example 9 in which
the content of the binder was 15%, there was a problem in that an
excessive curl occurred in the tipping paper. It was found that,
when the content of the binder was in a range of 5% to 10%, the
effect of reducing a tobacco smell on fingers caused by smoking was
excellent and the tipping paper curl issue could also be
solved.
Example 10
[0110] A smoking article was produced in the same way as in Example
8 described above with reference to Table 4, except that the
ethanol-based fragrance carrier ink contained 5.0% microcapsules.
As the microcapsules, microcapsules each having a diameter in a
range of about 1.5 .mu.m to 5.0 .mu.m were used, wherein a core of
each microcapsule was an ethanol-based fragrance, a shell of each
microcapsule was made of PVA, and Na.sub.2SO.sub.4 was used as a
cross-linking agent.
Example 11
[0111] A smoking article was produced in the same way as in Example
10 except that the ethanol-based fragrance carrier ink contained
10.0% binder.
Example 12
[0112] A smoking article was produced in the same way as in Example
11 except that the ethanol-based fragrance carrier ink contained
15.0% microcapsules.
Example 13
[0113] A smoking article was produced in the same way as in Example
12 except that the ethanol-based fragrance carrier ink contained
25.0% microcapsules.
Experimental Example 4: Evaluation of Index Materials of Tipping

Microcapsules Applied
[0114] In order to measure the effect of reducing a tobacco smell
on fingers when smoking cigarettes according to the examples and
the comparative example, changes in contents of vanillin and ethyl
vanillin in smoke were collected from the tipping paper and
analyzed. The results of the analysis are shown in Table 5
below.

[0115] As shown in Table 5, it was found that the amounts of
vanillin and ethyl vanillin components in the tipping paper
increased with an increase in the content of the microcapsules in
the fragrance carrier ink. However, in the case of Example 13 in
which the content of the microcapsules was 25%, the intensity of an
external scent generated while a cigarette was stored before being
smoked increased excessively, and the surface of the tipping paper
was contaminated due to breakage of the microcapsules. It was found
that, when the content of the microcapsules is in a range of 10% to
20%, the effect of reducing a tobacco smell on fingers caused by
smoking was excellent and the problems relating to the intensity of
the external scent and contamination of the surface of the tipping
paper could be solved.
Experimental Example 5: Evaluation of Workability of Printing on
Tipping Paper/Workability of Subsequent Process
[0116] In order to confirm workability of printing on the tipping
paper produced according to the examples of the present invention
and workability of a subsequent process for producing cigarettes
after the printing, physical characteristics of the tipping paper
were analyzed, and results thereof are shown in Table 6 below. In
Experimental Example 5, the analysis of physical characteristics of
tipping paper was carried out on tipping paper before the tipping
paper was assembled to each of the smoking articles according to
Example 8 and Examples 10 to 12.

[0117] As shown in Table 6, in all of Example 8 and Examples 10 to
12, the workability of printing on the tipping paper was good.
However, a problem of adhesion between front and rear surfaces of
the tipping paper did not occur, which may occur when the paper is
rolled while the ink is not completely dried and the ink on the
front surface is spread to the rear surface. The slip property was
good without a problem in that the surface of the tipping paper was
too slippery or rough, and a curl of the tipping paper was also
within an appropriate numerical value range. Accordingly, it was
confirmed that, according to the examples, there was no problem in
terms of the workability of fragrance carrier printing using the
fragrance carrier ink including the fragrance material, binder, and
the microcapsules.
Example 14
[0118] A tipping paper was removed from a cigarette produced for
testing of examples, and a material portion and a filter portion
were separated. A smoking article was produced by combining the
separated material portion and filter portion using a tipping paper
having a porosity of about 100 CU that was produced by applying the
OPV process and the fragrance carrier printing process using an
ethanol-based fragrance carrier ink containing 1.25% fragrance
material. Here, the fragrance material contained 5% vanillin and
10% ethyl vanillin.
Example 15
[0119] A smoking article was produced in the same way as in Example
14 except that the fragrance material contained 10% vanillin.
Example 16
[0120] A smoking article was produced in the same way as in Example
14 except that the fragrance material contained 20% vanillin.
Example 17
[0121] A smoking article was produced in the same way as in Example
14 except that the fragrance material contained 30% vanillin.
Example 18
[0122] A smoking article was produced in the same way as in Example
14 except that the fragrance material contained 40% vanillin.
Comparative Example 5
[0123] A smoking article was produced in the same way as in Example
15 except that, unlike in Examples 13 to 17, the fragrance printing
process was performed by stirring the fragrance material in the ink
without including the fragrance material in a carrier.
Experimental Example 6: Evaluation of Color Stability According to
Changes in Content of Vanillin in Fragrance Material
[0124] For evaluation of color stability of the tipping paper
according to changes in content of vanillin in the fragrance
material, the degrees of color change in cigarettes immediately
after production thereof and cigarettes after two months of
production were measured according to color difference (.DELTA.E)
in the CIELAB color space, and results thereof are shown in Table
7. The cigarettes were stored for two months under conditions of a
temperature of about 40.degree. C. and a relative humidity of about
60%.

Example 18 OPV + fragrance carrier(1.25%) [vanillin(40.0%), ethyl
vanillin(10.0%)] 2.20
[0125] From the results of analysis of Examples 14 to 18, it was
found that the degree of discoloration of the tipping paper
increased with an increase in the content of vanillin in the
fragrance material (while the content of ethyl vanillin was fixed
at 10%). Particularly, it can be seen that, in Examples 17 and 18
where the content of vanillin was higher than or equal to 30%, the
degree of discoloration increased sharply at which the
discoloration could even be seen with naked-eyes by visual
inspection. In contrast, the degree of discoloration of the tipping
paper was insignificant in Examples 14 to 16 in which the content
of vanillin was in a range of 5% to 20%. Also, from the results of
analysis of Example 16 and Comparative Example 5, it was confirmed
that, while the contents of vanillin and ethyl vanillin in the
fragrance material were the same, the degree of discoloration was
lower in the case in which fragrance carrier printing was performed
by including the fragrance material in the carrier material
(Example 16) as compared to the case in which fragrance printing
was performed without including the fragrance material in a carrier
(Comparative Example 5).
Example 19
[0126] A smoking article was produced in the same way as in Example
14 described above with reference to Table 7, except that the
fragrance material contained 20% vanillin and 5% ethyl
vanillin.
Example 20
[0127] A smoking article was produced in the same way as in Example
19 except that the fragrance material contained 20% ethyl
vanillin.
Example 21
[0128] A smoking article was produced in the same way as in Example
19 except that the fragrance material contained 30% ethyl
vanillin.
Example 22
[0129] A smoking article was produced in the same way as in Example
19 except that the fragrance material contained 40% ethyl
vanillin.
Experimental Example 7: Evaluation of Color Stability According to
Changes in Content of Ethyl Vanillin in Fragrance Material
[0130] For evaluation of color stability of the tipping paper
according to changes in content of ethyl vanillin in the fragrance
material, the degrees of color change of cigarettes immediately
after production and cigarettes after two months of production were
measured according to color difference (.DELTA.E) in the CIELAB
color space, and results thereof are shown in Table 8. The
cigarettes were stored for two months under conditions of a
temperature of about 40.degree. C. and a relative humidity of about
60%.

[0131] Similar to Example 6, the results of analysis in Examples 19
to 22 show that the degree of discoloration of the tipping paper
increased with the increase in the content of ethyl vanillin in the
fragrance material (while the content of vanillin was fixed at
20%). Particularly, it can be seen that, in Examples 20 to 22 in
which the content of ethyl vanillin was higher than or equal to
20%, the degree of discoloration increased sharply at which the
discoloration could even be seen by naked-eyes by visual
inspection. In contrast, the degree of discoloration of the tipping
paper was insignificant in Examples 16 and 19 in which the content
of ethyl vanillin was in a range of 5% to 10%.
Experimental Example 8: Smoking Sensory Evaluation Using Tipping
Paper to which Fragrance Carrier is Applied
[0132] In order to confirm sensory characteristics of the tipping
paper to which the fragrance carrier is applied according to the
present invention, sensory evaluation was performed with respect to
external scent intensity, tobacco taste intensity, intensity of the
tobacco smell on fingers after smoking, intensity of the scent
remaining on the fingers after smoking, and satisfaction with the
scent remaining on the fingers, for the smoking articles according
to Example 1, Comparative Example 1, and Comparative Example 4.
[0133] The sensory evaluation was performed by a panel of twenty
evaluators using the smoking articles according to Example 1,
Comparative Example 1, and Comparative Example 4, based on a scale
of 8 points.
[0134] FIG. 2 shows results of smoking sensory evaluation relating
to smoking articles stored at room temperature for two weeks after
being produced according to Example 1, Comparative Example 1, and
Comparative Example 4. FIG. 3 shows results of smoking sensory
evaluation relating to smoking articles stored at room temperature
for two months after being produced according to Example 1,
Comparative Example 1, and Comparative Example 4.
[0135] Referring to FIGS. 2 and 3, it can be seen that external
scent intensity (that is, the scent intensity before the cigarette
is rubbed by fingers of a smoker or saliva is delivered from the
smoker's mouth to the cigarette) increased noticeably in the
cigarette according to Comparative Example 4 to which fragrance
printing was applied as compared to the cigarette according to
Comparative Example 1 to which fragrance printing was not applied.
On the other hand, it can be seen that, in the cigarette according
to Example 1 to which fragrance carrier printing was applied, the
external scent intensity somewhat increased as compared to the
cigarette according to Comparative Example 1, but the external
scent intensity had a significantly lower numerical value as
compared to Comparative Example 4.
[0136] It can be seen that the intensity of the scent remaining on
the fingers after smoking increased significantly in Comparative
Example 4 and Example 1 as compared to Comparative Example 1 and
increased slightly in Example 1 as compared to Comparative Example
4. It can be seen that the intensity of the tobacco smell on the
fingers after smoking reduced in Comparative Example 4 and Example
1 as compared to Comparative Example 1 and reduced in Example 1 as
compared to Comparative Example 4.
[0137] Considering together the fact that the external scent
intensity had a lower numerical value in Example 1 as compared to
Comparative Example 4 and the fact that the intensity of the scent
remaining on the fingers after smoking had a higher numerical value
in Example 1 as compared to Comparative Example 4, it can be
confirmed that the amount of fragrance disseminated before smoking
relatively decreased and the amount of fragrance disseminated
during smoking relatively increased in the case in which the
fragrance material was included in a carrier and printed (Example
1) as compared to the case in which the fragrance material was
printed without being included in a carrier (Comparative Example
4).
[0138] Example 1, Comparative Example 1, and Comparative Example 4
showed no significant difference in terms of tobacco taste
intensity. Thus, the taste of tobacco smoke would not be affected
due to applying fragrance printing.
Experimental Example 9: Smoking Sensory Evaluation According to
Whether Microcapsules are Additionally Applied
[0139] In order to confirm changes in sensory characteristics
according to whether the microcapsules are added, sensory
evaluation was performed with respect to external scent intensity,
tobacco taste intensity, intensity of the tobacco smell on fingers
after smoking, intensity of the scent remaining on the fingers
after smoking, and satisfaction with the scent remaining on the
fingers, for the smoking articles according to Examples 10 to 12
and Comparative Example 1. The sensory evaluation was performed by
a panel of twenty evaluators using the smoking articles according
to Example 10 to 12 and Comparative Example 1, based on a scale of
8 points.
[0140] FIG. 4 shows results of smoking sensory evaluation relating
to smoking articles two weeks after production thereof according to
Examples 10 to 12 and Comparative Example 1.
[0141] Referring to FIG. 4, the external scent intensity, intensity
of the scent remaining on the fingers after smoking, and
satisfaction with the scent remaining on the fingers tended to
increase and the intensity of the tobacco smell on the fingers
after smoking tended to decrease with an increase in the content of
the binder and/or microcapsules in the fragrance carrier ink.
[0142] It was confirmed that, in all of Examples 10 to 12, an
increase in the intensity of the scent remaining on the fingers
after smoking as compared to Comparative Example 1 was larger than
an increase in external scent intensity as compared to Comparative
Example 1. Thus, it can be seen that, in all of Examples 10 to 12,
the fragrance was not substantially disseminated during storage of
the cigarettes and then was substantially disseminated according to
the smoking behavior of the smoker.
