Description
TECHNICAL FIELD
[0001] The present disclosure provides a cigarette including a
tobacco rod and a filter rod.
BACKGROUND ART
[0002] Recently, the demand for alternative methods to overcome the
shortcomings of general cigarettes has increased. For example,
there is an increasing demand for a method of generating aerosol by
heating an aerosol generating material in cigarettes, rather than
by burning cigarettes.
[0003] A cigarette includes a filter, and the filter is configured
to filter a certain component included in an aerosol or cool the
aerosol. When the filtering performance of the filter is too high,
the amount of aerosol transfer decreases, and when the filtering
performance of the filter is too low, certain components included
in the aerosol are not filtered.
[0004] Accordingly, research is being conducted on a filter having
appropriate performance by changing components constituting the
filter or by changing the structure of the filter.
DESCRIPTION OF EMBODIMENTS
Technical Problem
[0005] Provided is a cigarette using sucrose as a cooling material
configuring a cooling portion. The technical problems of the
present disclosure are not limited to the above-described
description, and other technical problems may be derived from the
embodiments to be described hereinafter.
Technical Solution to Problem
[0006] According to an aspect of the present disclosure, a
cigarette includes a tobacco rod and a filter rod connected to a
downstream end portion of the tobacco rod.
[0007] A portion of the filter rod according to the present
embodiment includes a cooling portion, and the cooling portion
includes sucrose as a cooling material.
Advantageous Effects of Disclosure
[0008] According to the present disclosure, a heated aerosol may be
effectively cooled by using sucrose as a cooling material
configuring a cooling portion of a cigarette. As the heated aerosol
passes through the cooling portion, the temperature of the sucrose
reaches the melting point thereof or higher, and phase change of
sucrose occurs. In this operation, sucrose may absorb the
surrounding heat, thereby cooling the heated aerosol.
[0009] In addition, since sucrose has the characteristic of
absorbing the surrounding moisture, an amount of aerosol may be
increased by adding moisture absorbed by the sucrose to the aerosol
passing through the cooling portion.

[0022] Hereinafter, embodiments of the present disclosure will be
described in detail with reference to the drawings.
[0023] FIGS. 1 through 3 are diagrams showing examples in which a
cigarette is inserted into an aerosol generating device.
[0024] Referring to FIG. 1, the aerosol generating device 10000 may
include a battery 11000, a controller 12000, and a heater 13000.
Referring to FIGS. 2 and 3, the aerosol generating device 10000 may
further include a vaporizer 14000. Also, a cigarette 20000 may be
inserted into an inner space of the aerosol generating device
10000.
[0025] FIGS. 1 through 3 illustrate components of the aerosol
generating device 10000, which are related to the present
embodiment. Therefore, it will be understood by one of ordinary
skill in the art related to the present embodiment that other
general-purpose components may be further included in the aerosol
generating device 10000, in addition to the components illustrated
in FIGS. 1 through 3.
[0026] Also, FIGS. 2 and 3 illustrate that the aerosol generating
device 10000 includes the heater 13000. However, according to
necessity, the heater 13000 may be omitted.
[0027] FIG. 1 illustrates that the battery 11000, the controller
12000, and the heater 130000 are arranged in series. Also, FIG. 2
illustrates that the battery 11000, the controller 12000, the
vaporizer 14000, and the heater 13000 are arranged in series. Also,
FIG. 3 illustrates that the vaporizer 14000 and the heater 13000
are arranged in parallel. However, the internal structure of the
aerosol generating device 10000 is not limited to the structures
illustrated in FIGS. 1 through 3. In other words, according to the
design of the aerosol generating device 10000, the battery 11000,
the controller 12000, the heater 13000, and the vaporizer 14000 may
be differently arranged.
[0028] When the cigarette 20000 is inserted into the aerosol
generating device 10000, the aerosol generating device 10000 may
operate the heater 13000 and/or the vaporizer 14000 to generate an
aerosol from the cigarette 20000 and/or the vaporizer 14000. The
aerosol generated by the heater 13000 and/or the vaporizer 14000 is
delivered to a user by passing through the cigarette 20000.
[0029] According to necessity, even when the cigarette 20000 is not
inserted into the aerosol generating device 10000, the aerosol
generating device 10000 may heat the heater 13000.
[0030] The battery 11000 supplies electric power to be used for the
aerosol generating device 10000 to operate. For example, the
battery 11000 may supply power to heat the heater 13000 or the
vaporizer 14000, and may supply power for operating the controller
12000. Also, the battery 11000 may supply power for operations of a
display, a sensor, a motor, etc. mounted in the aerosol generating
device 10000.
[0031] The controller 12000 may generally control operations of the
aerosol generating device 10000. In detail, the controller 12000
may control not only operations of the battery 11000, the heater
13000, and the vaporizer 14000, but also operations of other
components included in the aerosol generating device 10000. Also,
the controller 12000 may check a state of each of the components of
the aerosol generating device 10000 to determine whether or not the
aerosol generating device 10000 is able to operate.
[0032] The controller 12000 may include at least one processor. A
processor may be implemented as an array of a plurality of logic
gates or may be implemented as a combination of a general-purpose
microprocessor and a memory in which a program executable in the
microprocessor is stored. It will be understood by one of ordinary
skill in the art that the processor can be implemented in other
forms of hardware.
[0033] The heater 13000 may be heated by the power supplied from
the battery 11000. For example, when the cigarette 20000 is
inserted into the aerosol generating device 10000, the heater 13000
may be located inside the cigarette 20000. Thus, the heated heater
13000 may increase a temperature of an aerosol generating material
in the cigarette 20000.
[0034] The heater 13000 may include an electro-resistive heater.
For example, the heater 13000 may include an electrically
conductive track, and the heater 13000 may be heated when currents
flow through the electrically conductive track. However, the heater
13000 is not limited to the example described above and may include
all heaters which may be heated to a desired temperature. Here, the
desired temperature may be pre-set in the aerosol generating device
10000 or may be set as a temperature desired by a user.
[0035] As another example, the heater 13000 may include an
induction heater. In detail, the heater 13000 may include an
electrically conductive coil configured to heat a cigarette in an
induction heating method, and the cigarette may include a susceptor
which may be heated by the induction heater.
[0036] For example, the heater 13000 may include a tube-type
heating element, a plate-type heating element, a needle-type
heating element, or a rod-type heating element, and may heat the
inside or the outside of the cigarette 20000, according to the
shape of the heating element.
[0037] Also, the aerosol generating device 10000 may include a
plurality of heaters 13000. Here, the plurality of heaters 13000
may be inserted into the cigarette 20000 or may be arranged outside
the cigarette 20000. In addition, some of the plurality of heaters
13000 may be inserted into the cigarette 20000, and the others may
be arranged outside the cigarette 20000. In addition, the shape of
the heater 13000 is not limited to the shapes illustrated in FIGS.
1 through 3 and may include various shapes.
[0038] The vaporizer 14000 may generate an aerosol by heating a
liquid composition and the generated aerosol may pass through the
cigarette 20000 to be delivered to a user. In other words, the
aerosol generated via the vaporizer 14000 may move along an air
flow passage of the aerosol generating device 10000 and the air
flow passage may be configured such that the aerosol generated via
the vaporizer 14000 passes through the cigarette 20000 to be
delivered to the user.
[0039] For example, the vaporizer 14000 may include a liquid
storage, a liquid delivery element, and a heating element, but it
is not limited thereto. For example, the liquid storage, the liquid
delivery element, and the heating element may be included in the
aerosol generating device 10000 as independent modules.
[0040] The liquid storage may store a liquid composition. For
example, the liquid composition may be a liquid including a
tobacco-containing material having a volatile tobacco flavor
component, or a liquid including a non-tobacco material. The liquid
storage may be formed to be attached/detached to/from the vaporizer
14000 or may be formed integrally with the vaporizer 14000.
[0041] For example, the liquid composition may include water, a
solvent, ethanol, plant extract, spices, flavorings, or a vitamin
mixture. The spices may include menthol, peppermint, spearmint oil,
and various fruit-flavored ingredients, but are not limited
thereto. The flavorings may include ingredients capable of
providing various flavors or tastes to a user. Vitamin mixtures may
be a mixture of at least one of vitamin A, vitamin B, vitamin C,
and vitamin E, but are not limited thereto. Also, the liquid
composition may include an aerosol forming substance, such as
glycerin and propylene glycol.
[0042] The liquid delivery element may deliver the liquid
composition of the liquid storage to the heating element. For
example, the liquid delivery element may be a wick such as cotton
fiber, ceramic fiber, glass fiber, or porous ceramic, but is not
limited thereto.
[0043] The heating element is an element configured to heat the
liquid composition delivered by the liquid delivery element. For
example, the heating element may be a metal heating wire, a metal
hot plate, a ceramic heater, or the like, but is not limited
thereto. In addition, the heating element may include a conductive
filament such as nichrome wire and may be positioned as being wound
around the liquid delivery element. The heating element may be
heated by a current supply and may transfer heat to the liquid
composition in contact with the heating element, thereby heating
the liquid composition. As a result, aerosol may be generated.
[0044] For example, the vaporizer 14000 may be referred to as a
cartomizer or an atomizer, but it is not limited thereto.
[0045] The aerosol generating device 10000 may further include
general-purpose components in addition to the battery 11000, the
controller 12000, the heater 13000, and the vaporizer 14000. For
example, the aerosol generating device 10000 may include a display
capable of outputting visual information and/or a motor configured
to output haptic information. Also, the aerosol generating device
10000 may include at least one sensor (a puff detecting sensor, a
temperature detecting sensor, a cigarette insertion detecting
sensor, etc.). Also, the aerosol generating device 10000 may be
formed as a structure where, even when the cigarette 20000 is
inserted into the aerosol generating device 10000, external air may
be introduced or internal air may be discharged.
[0046] Although not illustrated in FIGS. 1 through 3, the aerosol
generating device 10000 and an additional cradle may form together
a system. For example, the cradle may be used to charge the battery
11000 of the aerosol generating device 10000. Alternatively, the
heater 13000 may be heated when the cradle and the aerosol
generating device 10000 are coupled to each other.
[0047] The cigarette 20000 may be similar as a general combustive
cigarette. For example, the cigarette 20000 may be divided into a
first portion including an aerosol generating material and a second
portion including a filter, etc. Alternatively, the second portion
of the cigarette 20000 may also include an aerosol generating
material. For example, an aerosol generating material made in the
form of granules or capsules may be inserted into the second
portion.
[0048] The entire first portion may be inserted into the aerosol
generating device 10000, and the second portion may be exposed to
the outside. Alternatively, only a portion of the first portion may
be inserted into the aerosol generating device 10000, or the entire
first portion and a portion of the second portion may be inserted
into the aerosol generating device 10000. The user may puff aerosol
while holding the second portion by the mouth of the user. In this
case, the aerosol is generated by the external air passing through
the first portion, and the generated aerosol passes through the
second portion and is delivered to the user's mouth.
[0049] For example, the external air may flow into at least one air
passage formed in the aerosol generating device 10000. For example,
the opening and closing and/or a size of the air passage formed in
the aerosol generating device 10000 may be adjusted by the user.
Accordingly, the amount of smoke and a smoking impression may be
adjusted by the user. As another example, the external air may flow
into the cigarette 20000 through at least one hole formed in a
surface of the cigarette 20000.
[0050] Hereinafter, an example of the cigarette 20000 will be
described with reference to FIG. 4.
[0051] FIG. 4 illustrates an example of a cigarette.
[0052] Referring to FIG. 4, the cigarette 20000 may include a
tobacco rod 21000 and a filter rod 22000. The first portion
described above with reference to FIGS. 1 through 3 may include the
tobacco rod 21000, and the second portion 32000 may include the
filter rod 22000.
[0053] FIG. 4 illustrates that the filter rod 22000 includes a
single segment. However, the filter rod 22000 is not limited
thereto. In other words, the filter rod 22000 may include a
plurality of segments. For example, the filter rod 22000 may
include a first segment configured to cool an aerosol and a second
segment configured to filter a certain component included in the
aerosol. Also, according to necessity, the filter rod 22000 may
further include at least one segment configured to perform other
functions.
[0054] The cigarette 2000 may be packaged via at least one wrapper
24000. The wrapper 24000 may have at least one hole through which
external air may be introduced or internal air may be discharged.
For example, the cigarette 20000 may be packaged via one wrapper
24000. As another example, the cigarette 20000 may be doubly
packaged via at least two wrappers 24000. For example, the tobacco
rod 21000 may be packaged via a first wrapper, and the filter rod
22000 may be packaged via a second wrapper. Also, the tobacco rod
21000 and the filter rod 22000, which are respectively packaged via
separate wrappers, may be coupled to each other, and the entire
cigarette 20000 may be packaged via a third wrapper. When each of
the tobacco rod 21000 and the filter rod 22000 includes a plurality
of segments, each segment may be packaged via a separate wrapper.
Also, the entire cigarette 20000 including the plurality of
segments, which are respectively packaged via the separate wrappers
and which are coupled to each other, may be re-packaged via another
wrapper.
[0055] The tobacco rod 21000 may include an aerosol generating
material. For example, 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, but it is not limited
thereto. Also, the tobacco rod 21000 may include other additives,
such as flavors, a wetting agent, and/or organic acid. Also, the
tobacco rod 21000 may include a flavored liquid, such as menthol or
a moisturizer, which is injected to the tobacco rod 21000.
[0056] The tobacco rod 21000 may be manufactured in various forms.
For example, the tobacco rod 21000 may be formed as a sheet or a
strand. Also, the tobacco rod 21000 may be formed as a pipe
tobacco, which is formed of tiny bits cut from a tobacco sheet.
Also, the tobacco rod 21000 may be surrounded by a heat conductive
material. For example, the heat-conducting material may be, but is
not limited to, a metal foil such as aluminum foil. For example,
the heat conductive material surrounding the tobacco rod 21000 may
uniformly distribute heat transmitted to the tobacco rod 21000, and
thus, the heat conductivity applied to the tobacco rod may be
increased and taste of the tobacco may be improved. Also, the heat
conductive material surrounding the tobacco rod 21000 may function
as a susceptor heated by the induction heater. Here, although not
illustrated in the drawings, the tobacco rod 21000 may further
include an additional susceptor, in addition to the heat conductive
material surrounding the tobacco rod 21000.
[0057] The filter rod 22000 may include a cellulose acetate filter.
Shapes of the filter rod 22000 are not limited. For example, the
filter rod 22000 may include a cylinder-type rod or a tube-type rod
having a hollow inside. Also, the filter rod 22000 may include a
recess-type rod. When the filter rod 22000 includes a plurality of
segments, at least one of the plurality of segments may have a
different shape.
[0058] The filter rod 22000 may be formed to generate flavors. For
example, a flavoring liquid may be injected onto the filter rod
22000, or an additional fiber coated with a flavoring liquid may be
inserted into the filter rod 22000.
[0059] Also, the filter rod 22000 may include at least one capsule
23000. Here, the capsule 23000 may generate a flavor or an aerosol.
For example, the capsule 23000 may have a configuration in which a
content containing a flavoring material is wrapped with a film. For
example, the capsule 23000 may have a spherical or cylindrical
shape, but is not limited thereto.
[0060] When the filter rod 22000 includes a segment configured to
cool the aerosol, the cooling segment may include a polymer
material or a biodegradable polymer material. For example, the
cooling segment may include pure polylactic acid alone, but the
material for forming the cooling segment is not limited thereto. In
some embodiments, the cooling segment may include a cellulose
acetate filter having a plurality of holes. However, the cooling
segment is not limited to the above-described example and is not
limited as long as the cooling segment cools the aerosol.
[0061] Although not illustrated in FIG. 4, the cigarette 20000
according to an embodiment may further include a front-end filter.
The front-end filter may be located on a side of the tobacco rod
21000, the side facing the filter rod 22000. The front-end filter
may prevent the tobacco rod 21000 from being detached outwards and
prevent a liquefied aerosol from flowing into the aerosol
generating device 10000 (FIGS. 1 through 3) from the tobacco rod
21000, during smoking.
[0062] FIG. 5 illustrates an example of a cigarette including a
cooling portion according to an embodiment.
[0063] Referring to FIG. 5, a cigarette 5 includes a tobacco rod
510 and a filter rod 520 connected to a downstream end portion of
the tobacco rod 510. The filter rod 520 may include a cooling
portion 521, a tube portion 522, and an acetate portion 523.
[0064] As shown in FIG. 5, in an embodiment, the cooling portion
521 may be connected to the downstream end portion of the tobacco
rod 510, the tobacco rod 510 may be connected to a downstream end
portion of the cooling portion 521, and the acetate portion 523 may
be connected to a downstream end portion of the tube portion 522.
That is, segments may be located in an order of the tobacco rod
510, the cooling portion 521, the tube portion 522, and the acetate
portion 523.
[0065] In another embodiment, the tube portion 522 may be connected
to the downstream end portion of the tobacco rod 510, the cooling
portion 521 may be connected to the downstream end portion of the
tube portion 522, and the acetate portion 523 may be connected to
the downstream end portion of the cooling portion 521. In other
words, segments may be located in an order of the tobacco rod 510,
the tube portion 522, the cooling portion 521, and the acetate
portion 523.
[0066] However, types of filter segments included in the filter rod
520 and arrangement order of filter segments configuring the filter
rod 520 are not limited thereto.
[0067] The cigarette 5 may be packaged via a plurality of wrappers.
The plurality of wrappers may be formed as a general wrapper, and
may be a porous wrapper or a non-porous wrapper.
[0068] For example, the tobacco rod 510 may be packaged via a first
wrapper, and the tube portion 522 may be packaged via a second
wrapper. In addition, the cooling portion 521 may be packaged via a
third wrapper, and the acetate portion 523 may be packaged via a
fourth wrapper.
[0069] A fifth wrapper may be wrapped around outer sides of the
first wrapper, the second wrapper, and the third wrapper. In other
words, the tobacco rod 510, the tube portion 522, and the cooling
portion 521 of the cigarette 5 may be further packaged via the
fifth wrapper. In addition, a sixth wrapper may be wrapped around
at least a portion of the fifth wrapper and an outer side of the
fourth wrapper. That is, at least a portion of the cooling portion
521 of the cigarette 5 and the acetate portion 523 may be further
packaged via the sixth wrapper.
[0070] The diameter of the cigarette 5 may be within a range of 5
mm to 9 mm, and the length of the cigarette 5 may be about 48 mm,
but are not limited thereto. For example, the length of the tobacco
rod 510 may be about 12 mm, the length of the tube portion 522 may
be about 10 mm, the length of the cooling potion 521 may be about
14 mm, and the length of the acetate portion 523 may be about 12
mm, but are not limited thereto.
[0071] The tobacco rod 510 includes an aerosol generating material.
For example, 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.
[0072] In addition, the tobacco rod 510 may include other
additives, such as flavors, a wetting agent, and/or organic acid.
For example, flavors may include licorice, saccharose, fructose
syrup, isosweet, cocoa, lavender, cinnamon, carudamon, celery,
fenugreek, cascarilla, white sandalwood, monarda didyma, geranium,
honey essence, rose oil, vanilla, lemon oil, orange oil, mint oil,
cinnamon, caraway, cognac, jasmine, chamomile, methol, cinnamon,
ylang-ylang, salvia, spearmint, ginger, coriander, coffee, or the
like. In addition, the wetting agent may include glycerin,
propylene glycol, or the like.
[0073] For example, the tobacco rod 510 may be filled with a
reconstituent tobacco sheet. As another example, the tobacco rod
510 may be filled with tiny bits. Herein, the tiny bits may be
generated by finely cutting the reconstituent tobacco sheet. As
another example, the tobacco rod 510 may be filled with a plurality
of tobacco strands in which the consistuent tobacco sheet is finely
cut. For example, the tobacco rod 510 may be formed by combining
the plurality of tobacco strands in the same direction (parallel)
or randomly.
[0074] In addition, before an operation in which the tobacco rod
510 is packaged via a wrapper, a flavored liquid, such as menthol
or a moisturizer, may be injected to the center of the tobacco rod
510.
[0075] The tube portion 522 may include a cellulose acetate filter.
For example, the tube portion 522 may include a tube-type structure
including a hollow inside. The length of the tube portion 522 may
be an appropriate length within a range of about 4 mm to about 30
mm, but is not limited thereto. Preferably, the length of the tube
portion 522 may be 10 mm, but is not limited thereto. The diameter
of the hollow included in the tube portion 522 may be an
appropriate diameter within a range of about 2 mm to 4.5 mm, but is
not limited thereto.
[0076] The hardness of the tube portion 522 may be controlled by
adjusting the content of plasticizer when manufacturing the tube
portion 522. In addition, the tube portion 522 may be manufactured
by inserting a structure such as a film, tube, or the like of the
same or different materials into the inside of the tube portion 522
(for example, the hollow).
[0077] The tube portion 522 may be manufactured by using a
cellulose acetate filter. Accordingly, an internal material of the
tobacco rod 510 may be prevented from being pushed back, and a
cooling effect of an aerosol may be generated.
[0078] Sucrose (or saccharose) may be included in the cooling
portion 521 as a cooling material. The melting point of sucrose is
about 160.degree. C. to about 180.degree. C. When the temperature
of the sucrose reaches the melting point or higher, caramelization
performs, and in this operation, surrounding heat is absorbed.
[0079] The cooling portion 521 cools an aerosol generated by the
heater heating the tobacco rod 510. Accordingly, a user may puff
the aerosol which is cooled to a suitable temperature.
[0080] In detail, when the cigarette 5 is inserted into an aerosol
generating device, the aerosol generating device operates a heater
to heat the tobacco rod 510 of the cigarette 5. When a user bites
the acetate portion 523 of the cigarette 5 inserted into an aerosol
generating device and inhales air, air from the outside flows to
the inside of the cigarette 5, and an aerosol is generated in an
operation in which the introduced air passes through the tobacco
rod 510 heated by a heater.
[0081] As the aerosol generated in the tobacco rod 510 passes
through the cooling portion 521, the temperature of sucrose, which
is a cooling material included in the cooling portion 521, rises.
When the temperature of the sucrose reaches the melting point or
higher, caramelization may perform, and in this operation,
surrounding heat may be absorbed to cool the heated aerosol.
Accordingly, a user may puff the aerosol which is cooled to a
suitable temperature.
[0082] In addition, the sucrose included in the cooling portion 521
has a characteristic of absorbing and not releasing surrounding
moisture. Therefore, moisture absorbed by the sucrose may be added
to the aerosol passing through the cooling portion 521 to increase
an amount of aerosol, and the amount of aerosol may be maintained
until the latter half of smoking.
[0083] In addition, when the sucrose is a sugar concentrate with
high concentration, the sucrose has high preservative properties
due to high osmotic pressure, and thus storage stability may be
ensured.
[0084] In an embodiment, the sucrose included in the cooling
portion 521 may have a bead type, a sheet type, or a block
type.
[0085] The bead-form sucrose may have a spherical shape or a fillet
shape. The sheet-form sucrose may include any one material of a
porous paper or an edible film. The block-form sucrose may have a
cylindrical shape, a tube shape, or a nine-holed briquette
shape.
[0086] The length or diameter of the cooling portion 521 may be
variously determined according to the shape of the cigarette 5. For
example, the length of the cooling portion 521 may be suitably used
within a range of about 7 mm to about 20 mm. Preferably, the length
of the cooling portion 521 may be 14 mm, but is not limited
thereto.
[0087] As shown in FIG. 5, as the cooling portion 521 is located in
the upstream portion of the cigarette 5 than the tube portion 522
and the acetate portion 523, thereby preventing the tube portion
522 and the acetate portion 523 from being melted or contracted by
heat.
[0088] FIG. 6 is an example diagram illustrating a bead-form
cooling material according to an embodiment.
[0089] Referring to FIG. 6, a cooling portion 600 may include a
first filter element 610, a second filter element 620, and a
cooling material 630.
[0090] The first filter element 610 may be located at one side end
portion of the cooling portion 600, and the second filter element
620 may be located at the other side end portion. In addition, the
first filter element 610 and the second filter element 620 may be
spaced apart by a certain distance to form a cavity between the
first filter element 610 and the second filter element 620. The
cooling material 630 including sucrose may be located in the
cavity.
[0091] In an embodiment, the first filter element 610 and the
second filter element 620 may include a tube-type structure
including a hollow inside, but the shape of the first filter
element 610 and the second filter element 620 are not limited
thereto.
[0092] The cooling material 630 located in the cavity between the
first filter element 610 and the second filter element 620 may be a
bead-form. The bead-form cooling material 630 may have a spherical
shape or a fillet shape.
[0093] In an embodiment, the bead-form cooling material 630 may be
manufactured by stacking a sucrose layer on a sucrose seed by using
a tangential spray method or a top spray method. The bead-form
cooling material 630 manufactured in this method may have a
spherical shape or a fillet shape.
[0094] Also, the surface of the bead-form cooling material 630 may
be coated. A film-forming polymer, gum, or starch may be used as a
coating material coating the surface of the cooling material 630.
For example, as the coating material coating the surface of the
cooling material 630, shellac, hyroxypropyl methylcellulose (HPMC),
corn starch, or a combination thereof may be used. Preferably, the
coating material coating the surface of the cooling material 630
may be shellac. Inserting the cooling material 630 into the cooling
portion 600 may become easier and storage property of the cooling
material 630 may be improved by coating the surface of the cooling
material 630.
[0095] In addition, fine protrusions may be formed on at least a
portion of the surface of the cooling material 630. By forming fine
protrusions on the surface of the cooling material 630, an area in
which the cooling material 630 contacts an aerosol passing through
the cooling material 630 may increase. As a result, a cooling
effect of the cooling material 630 may be improved.
[0096] In an embodiment, based on the total volume of the cooling
portion 600, a ratio of the volume occupied by the bead-form
cooling material 630 may be about 30% to about 35%. Also, the
diameter of the bead-form cooling material 630 may be about 3 mm to
about 5 mm, and the weight of the bead-form cooling material 630
may be about 0.3 g to about 1.0 g.
[0097] The first filter element 610, the second filter element 620,
and the cooling material 630 included in the cooling portion 600
may be packaged via at least one wrapper 640.
[0098] FIGS. 7A and 7B are example diagrams illustrating a
sheet-form cooling material according to an embodiment.
[0099] A cooling material 710 including sucrose may have a sheet
form.
[0100] In an embodiment, the cooling material 710 may be a porous
paper sheet. The porous paper sheet may be a material having
elasticity and flexibility, and for example, may include a
cellulosic material used in wrappers such as birch and bamboo.
[0101] When the cooling material 710 includes a porous paper sheet,
a coating material including sucrose (for example, sucrose powder),
distilled water, and starch syrup may be coated on the porous paper
sheet. Starch syrup included in the coating material may control
the viscosity of the coating material and suppress the
precipitation of sugar/glucose crystals.
[0102] Materials included in the coating material are not limited
to the above-described examples, and additional materials may be
further added to increase the efficiency of coating operation and
drying operation of the cooling material 710.
[0103] In an embodiment, the concentration of sucrose (for example,
sucrose powder) may be 30% wt to 70% wt relative to the total
concentration of the coating material coated on a porous paper, and
the total weight of starch syrup may be 40% or less relative to the
total weight of the coating material, but are not limited
thereto.
[0104] In another embodiment, the cooling material 710 may be an
edible film.
[0105] The edible film may include a biodegradable film material.
For example, starch or cellulose and derivatives thereof, such as
pectin, alginate, carrageenan, chitosan, or the like, may be used
as the biodegradable film material. Also, pullulan having excellent
coating and film forming ability may be further added.
[0106] The cooling material 710 in an edible form may be formed by
mixing the above-stated biodegradable film material with
sucrose.
[0107] In another embodiment, the cooling material 710 in a sheet
form may have a viscosity such as wax. The cooling material 710 may
include sucrose, an acid-based solution, and distilled water to
have a viscosity such as wax. The acid-based solution may be lemon
juice, vinegar, or the like.
[0108] Referring to FIG. 7A, the cooling material 710 in a sheet
form may be wound. When a wound cooling material 720 is located
inside a cooling portion 700, the wound cooling material 720 may be
located inside the cooling portion 700 in a longitudinal direction
of the cooling portion 700 such that an airflow (for example, an
aerosol) may pass through. In other words, the wound cooling
material 720 may be located inside the cooling portion 700 such
that the longitudinal direction of the wound cooling material 720
is parallel to the longitudinal direction of the cooling portion
700.
[0109] In FIG. 7A, a plurality of wound cooling materials 720 may
be located in the cooling portion 700, such that a honeycomb-shaped
airflow path may be formed inside the cooling portion 700.
[0110] In addition, referring to FIG. 7B, the cooling material 710
in a sheet form may form various patterns and be located in the
cooling portion 700 such that an airflow may pass along the
longitudinal direction of the cooling portion 700. For example, a
cooling material 731 wound in an irregular pattern, a swirling
cooling material 732, or a concentric circle-form cooling material
733 may be located inside the cooling portion 700.
[0111] FIGS. 8A and 8B are example diagrams illustrating a
block-form cooling material according to an embodiment.
[0112] A cooling material including sucrose may have a block form.
In an embodiment, a block-form cooling material may be manufactured
in a method in which syrup or powdered-form sucrose is poured into
a mold to harden.
[0113] Referring to FIG. 8A, the block-form cooling material may
have a circular shape, a tube shape including a hollow inside, or a
nine-holed briquette shape in which a plurality of holes
penetrating the inside are formed. However, the block-form cooling
material is not limited thereto.
[0114] Referring to FIG. 8B, at least one channel may be formed on
an outer circumferential surface of the block-form cooling
material. The at least one channel formed on the outer
circumferential surface of the cooling material may be formed in
the longitudinal direction of the cooling portion such that an
airflow may pass along the longitudinal direction of the cooling
material.
[0115] In an embodiment, the at least one channel formed on the
outer circumferential surface of the cooling material may form a
regular or irregular pattern of a straight line, a curved line,
spiral or zigzag. Also, convex protrusions or concave grooves may
be formed on the outer circumferential surface of the cooling
material to perform a channel function allowing the airflow passing
through.
[0116] FIG. 9 is a diagram explaining a cooling effect of using
sucrose as a cooling material according to an embodiment.
[0117] Referring to FIG. 9, each of cigarettes 910 to 970 may
include a tobacco rod, a tube portion, a cooling portion, and an
acetate portion.
[0118] While the tobacco rods of the cigarettes 910 to 970 are
being heated, air is introduced from the outside to the inside of
the cigarettes 910 to 970 whenever a user bites the acetate
portions of the cigarettes 910 to 970 and puffs. An aerosol is
produced in an operation in which the introduced air passes through
the heated tobacco rod.
[0119] Table 1 below is a result of measuring the temperature of
aerosols reaching an upstream end portion of the acetate portions
after the aerosols generated from the tobacco rods have passed
through the cooling portions, by using the cigarettes 910 to 970
according to first to seventh embodiments. In other words, through
Table 1 below, how much the aerosols have cooled by passing through
the cooling portions in each of the first to seventh embodiments
may be confirmed.
[0120] For the measurement of Table 1, the puff volume was set to
55 ml, the puff time was set to 2 seconds, the puff cycle was set
to 20 seconds, and the number of puffs was set to 12. In Table 1,
the maximum temperature refers to an average value of maximum
temperatures during the puff period for each puff, and the average
temperature refers to an average value of average temperatures
during the puff period for each puff.

[0121] Hereinafter, the tube portions and the cooling portions of
the first to seventh embodiments are tube-type structures including
a hollow inside.
[0122] In the first embodiment, the tube portion of the cigarette
910 is cellulose acetate (CA), and the cooling portion is poly
lactic acid (PLA) woven fabric. As a result measuring the
temperatures of aerosols at a measurement position by using the
cigarette 910 of the first embodiment, the maximum temperature was
79.2.degree. C. and the average temperature was 65.8.degree. C.
[0123] In the second embodiment, the tube portion of the cigarette
920 is CA, and the cooling portion is also CA. As a result
measuring the temperatures of aerosols at a measurement position by
using the cigarette 920 of the second embodiment, the maximum
temperature was 68.8.degree. C. and the average temperature was
57.7.degree. C.
[0124] In the third embodiment, the tube portion of the cigarette
930 is a reconsistuent tobacco sheet, and the cooling portion is
CA. As a result measuring the temperatures of aerosols at a
measurement position by using the cigarette 930 of the third
embodiment, the maximum temperature was 86.8.degree. C. and the
average temperature was 69.0.degree. C.
[0125] In the fourth embodiment, the tube portion of the cigarette
940 is a paper, and the cooling portion is CA. As a result
measuring the temperatures of aerosols at a measurement position by
using the cigarette 940 of the fourth embodiment, the maximum
temperature was 69.5.degree. C. and the average temperature was
55.7.degree. C.
[0126] In the fifth embodiment, the tube portion of the cigarette
950 is a CA, and the cooling portion is a reconstituent tobacco
sheet. As a result measuring the temperatures of aerosols at a
measurement position by using the cigarette 950 of the fifth
embodiment, the maximum temperature was 77.3.degree. C. and the
average temperature was 61.8.degree. C.
[0127] In the sixth embodiment, the tube portion of the cigarette
960 is a CA, and the cooling portion is a paper. As a result
measuring the temperatures of aerosols at a measurement position by
using the cigarette 960 of the sixth embodiment, the maximum
temperature was 85.7.degree. C. and the average temperature was
72.7.degree. C.
[0128] In the seventh embodiment, the tube portion of the cigarette
970 is a CA, and the cooling portion is sucrose. As a result
measuring the temperatures of aerosols at a measurement position by
using the cigarette 970 of the seventh embodiment, the maximum
temperature was 47.3.degree. C. and the average temperature was
42.6.degree. C.
[0129] In other words, as a result measuring temperatures of
aerosols at a measurement position by using the cigarettes 910 to
970 according to the first to seventh embodiments, the maximum
temperature and the average temperature of the seventh embodiment
in which the cooling material is sucrose were measured to be the
lowest.
[0130] When the temperature of sucrose included in the cooling
portion reaches the melting point or higher, caramelization may
perform, and in this operation, surrounding heat may be absorbed to
effectively cool the heated aerosol. Accordingly, a user may puff
the aerosol cooled to a suitable temperature.
[0131] Those of ordinary skill in the art related to the present
embodiments may understand that various changes in form and details
can be made therein without departing from the scope of the
characteristics described above. The disclosed methods should be
considered in a descriptive sense only and not for purposes of
