Definitions
- the present invention relates to a smoking article including a multilayer medium portion, and more particularly, to a smoking article including a multilayer medium portion that allows a plurality of tobacco flavors to be tasted in one smoking article.
- Smoke or an aerosol generated in smoking articles moves from upstream to downstream and is delivered to a smoker so that the smoker feels satisfied with smoking. There are several factors that determine smoking satisfaction, but the most important factor is the tobacco flavor that the smoker tastes.
- the present invention is directed to providing a new type of smoking article that allows a smoker to taste various tobacco flavors in one smoking article.
- the present invention is also directed to providing a smoking article capable of allowing the tobacco flavor to gradually change over smoking time, thus increasing a user's satisfaction with smoking.
- An embodiment of the present invention provides a smoking article including a multilayer medium portion, the smoking article including a filter portion and a medium portion including a first smoking material portion and a second smoking material portion, wherein the first smoking material portion and the second smoking material portion are disposed in a form in which the first smoking material portion is surrounded entirely or partially by the second smoking material portion in a longitudinal direction of the medium portion, and tobacco raw materials included in the first smoking material portion and tobacco raw materials included in the second smoking material portion are different.
- the first smoking material portion and the second smoking material portion may further include additives in addition to the tobacco raw materials, and types and composition ratios of the additives included in the first smoking material portion may be different from types and composition ratios of the additives included in the second smoking material portion.
- a transverse cross-section of the first smoking material portion may have one of a circular shape, an elliptical shape, a regular polygon shape, and an irregular polygon shape
- the second smoking material portion may have a shape surrounding the first smoking material portion
- the smoking article may further include a wrapper that wraps around an outer side surface of the first smoking material portion, and the first smoking material portion and the second smoking material portion may be physically partitioned by the wrapper.
- the wrapper may have characteristics of at least one of porous wrapping paper, nonporous wrapping paper, grease-resistant wrapping paper, and water-resistant wrapping paper with a coated surface.
- a resistance to draw of the first smoking material portion and a resistance to draw of the second smoking material portion may be different.
- a packing density of the tobacco raw materials included in the first smoking material portion and a packing density of the tobacco raw materials included in the second smoking material portion may be different.
- the first smoking material portion and the second smoking material portion may include a plurality of tobacco strands produced using tobacco raw materials, and the tobacco strands included in one of the first smoking material portion and the second smoking material portion may be packed to be parallel to each other in the longitudinal direction of the medium portion, and the tobacco strands included in the other one may be packed in random arrays.
- aerosols generated in the first smoking material portion and the second smoking material portion may move in a downstream direction and be mixed in the filter portion, and components of the aerosol generated in the first smoking material portion and components of the aerosol generated in the second smoking material portion may be different.
- an amount of the aerosol generated in the first smoking material portion and an amount of the aerosol generated in the second smoking material portion may be different.
- a smoking article including a multilayer medium portion, there is an effect of allowing a smoker to taste various tobacco flavors in one smoking article.
- smoking article may refer to anything capable of generating an aerosol, such as tobacco (cigarette) and cigar.
- the smoking article may include an aerosol-generating material or an aerosol-forming substrate.
- the smoking article may include a solid material based on tobacco raw materials, such as reconstituted tobacco leaves, shredded tobacco, and reconstituted tobacco.
- a smoking material may include a volatile compound.
- upstream or “upstream direction” refers to a direction moving away from an oral region of a user smoking a smoking article 100
- downstream or “downstream direction” refers to a direction approaching the oral region of the user smoking the smoking article 100
- the smoking article 100 may be a combustion-type cigarette or a heating-type cigarette or the like that is used with an electronic cigarette device.
- FIG. 1 is a partially cut-out perspective view of a smoking article including a multilayer medium portion according to an embodiment of the present invention.
- the smoking article 100 including a multilayer medium portion includes a filter portion 110 and a medium portion 130.
- the filter portion 110 is a region disposed downstream from the medium portion 130 and through which an aerosol material generated in the medium portion 130 passes right before being inhaled by the user.
- the filter portion 110 may be formed of various materials.
- the filter portion 110 may be produced as a cellulose acetate filter, a recessed filter including a hollow, or the like.
- a length of the filter portion 110 may be appropriately selected within a range of 4 mm to 30 mm, and a diameter of the filter portion 110 may be appropriately selected within a range of 5 mm to 8 mm, but the present invention is not limited thereto.

Abstract
Description
- The present invention relates to a smoking article including a multilayer medium portion, and more particularly, to a smoking article including a multilayer medium portion that allows a plurality of tobacco flavors to be tasted in one smoking article.
- Smoke or an aerosol generated in smoking articles moves from upstream to downstream and is delivered to a smoker so that the smoker feels satisfied with smoking. There are several factors that determine smoking satisfaction, but the most important factor is the tobacco flavor that the smoker tastes.
- Meanwhile, since smokers want to enjoy various tobacco flavors in one smoking article, in order to meet the smokers' desire, tobacco manufacturers produce and sell products in which capsules are embedded in smoking article filters. When the capsules embedded in the filters are crushed, the smokers may taste various flavors due to flavoring agents filled in the capsules.
- However, since inherent tobacco flavors of smoking articles vary according to tobacco leaves filled in the smoking articles, there have been limitations in allowing smokers to taste various tobacco flavors just by the capsules embedded in the filters.
- Thus, the need has arisen for new types of smoking articles that allow various tobacco flavors to be tasted in one smoking article.
- The present invention is directed to providing a new type of smoking article that allows a smoker to taste various tobacco flavors in one smoking article.

portion 150 may be variously set according to the shape of thesmoking article 100. For example, the length of the coolingportion 150 may be appropriately selected within a range of 7 mm to 20 mm. Preferably, the length of the coolingportion 150 may be about 14 mm, but the present invention is not limited thereto. - The cooling
portion 150 may be made by weaving polymer fibers. In this case, a flavoring liquid may also be applied to the fibers made of polymer. Alternatively, separate fibers to which a flavoring liquid is applied and fibers made of polymer may be woven together to produce the coolingportion 150. - Alternatively, the cooling
portion 150 may also be formed by a crimped polymer sheet. The polymer according to an embodiment of the present invention may be produced using a material selected from the group consisting of polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), polylactic acid (PLA), cellulose acetate (CA), and aluminum foil. - Since the cooling
portion 150 is formed using the woven polymer fibers or the crimped polymer sheet, the coolingportion 150 may include at least one channel formed in a longitudinal direction of thesmoking article 100. Here, the channel refers to a passage through which air or the aerosol generated in themedium portion 130 passes. - The
support element 170 prevents a phenomenon in which, when thesmoking article 100 is inserted into an electronic cigarette device or the like, the internal elements of thesmoking article 100 are pushed in the downstream direction by a heater or the like included in the electronic cigarette device. Also, thesupport element 170 may cool the aerosol generated in themedium portion 130. - The
support element 170 according to an embodiment of the present invention may be a cellulose acetate filter. For example, thesupport element 170 may be a tubular structure having a hollow formed therein. - The length and diameter of the
support element 170 may be variously set according to the shape of thesmoking article 100.

FIG. 3 is a perspective view of a smoking article including a multilayer medium portion according to still another embodiment of the present invention. - A
smoking article 100 including a multilayer medium portion according to still another embodiment of the present invention may, in addition to including afilter portion 110, amedium portion 130, and asupport element 170, further include afront plug 190. - Since the
filter portion 110, themedium portion 130, and thesupport element 170 of thesmoking article 100 illustrated inFIG. 3 are identical to those described above with reference toFIGS. 1 and 2 , descriptions thereof will be omitted to avoid repeated description. - The
front plug 190 may be a cellulose acetate filter. Alternatively, thefront plug 190 may be formed of a paper filter, a porous molded product, or the like. The length of thefront plug 190 according to an embodiment of the present invention may be in a range of 4 mm to 15 mm, but the present invention is not limited thereto. Thefront plug 190 may be colored or flavored. - The
front plug 190 serves to prevent tobacco raw materials included in themedium portion 130 from being discharged to the outside. - Hereinafter, the structure of the
medium portion 130 of thesmoking article 100 according to an embodiment of the present invention will be described in detail. -
FIG. 4 is a transverse cross-sectional view of a smoking article including a multilayer medium portion according to an embodiment of the present invention. - Specifically,
FIG. 4 illustrates a transverse cross-sectional view of themedium portion 130. As described above, themedium portion 130 may include the firstsmoking material portion 132 and the secondsmoking material portion 134, and the firstsmoking material portion 132 may be surrounded by the secondsmoking material portion 134. - Referring to
FIG. 4 , the firstsmoking material portion 132 disposed inside themedium portion 130 and the secondsmoking material portion 134 surrounding the firstsmoking material portion 132 may have circular cross-sections and concentric cylindrical shapes. However, the shape of the cross-section of the firstsmoking material portion 132 is not limited to the circular shape and may, of course, be various other shapes. For example, the cross-section of the firstsmoking material portion 132 may have an elliptical shape, a regular polygon shape, an irregular polygon shape, or the like. - In the case in which the cross-section of the first
smoking material portion 132 has one of the shapes listed above, the cross-section of the secondsmoking material portion 134 may have a shape surrounding the firstsmoking material portion 132. - Meanwhile, raw materials constituting the first
smoking material portion 132 and raw materials constituting the secondsmoking material portion 134 may be different. Specifically, pieces of tobacco leaves, tobacco stems, and/or fine tobacco powder generated during tobacco processing which are the raw materials of the firstsmoking material portion 132 may be different from those included in the secondsmoking material portion 134. - Also, the first
smoking material portion 132 and the secondsmoking material portion 134 may each include various additives in addition to the tobacco raw materials, and the additives included in the firstsmoking material portion 132 and the secondsmoking material portion 134 may also be different. Alternatively, the additives added to the firstsmoking material portion 132 and the secondsmoking material portion 134 may be the same, but composition ratios thereof may be different. - Therefore, it is possible to achieve an effect of allowing the smoker to taste various tobacco flavors over smoking time.
-
FIG. 5 is a transverse cross-sectional view of a smoking article including a multilayer medium portion according to another embodiment of the present invention. - As described above, the
medium portion 130 according to an embodiment of the present invention includes the firstsmoking material portion 132 and the secondsmoking material portion 134 which are produced using different raw materials. Thus, the raw materials included in the smoking material portions may be mixed during a production process or a distribution process in some cases. - Accordingly, the
medium portion 130 according to an embodiment of the present invention may further include awrapper 136 that wraps around an outer side surface of the firstsmoking material portion 132. Consequently, the firstsmoking material portion 132 and the secondsmoking material portion 134 are physically partitioned by thewrapper 136. - The
wrapper 136 according to an embodiment of the present invention may be produced using general wrapping paper that is not treated to be grease-resistant. In this case, thewrapper 136 may be porous wrapping paper or nonporous wrapping paper. - In the case in which the
wrapper 136 is the porous wrapping paper, the porosity may be, in Cooperation Center for Scientific Research Relative to Tobacco (CORESTA) units (CU), 6,500 CU or higher, and preferably, 24,000 CU or higher. On the other hand, in the case in which the wrapper is the nonporous wrapping paper, the porosity may be in a range of 10 CU to 200 CU. - According to another embodiment of the present invention, the
wrapper 136 may be produced using grease-resistant wrapping paper. This is because, in the case in which additives such as oil and fat are included in at least one of the firstsmoking material portion 132 and the secondsmoking material portion 134, the additives included in the smoking material portions may permeate through thewrapper 136 and mix with each other. - According to still another embodiment of the present invention, the
wrapper 136 may be produced using water-resistant wrapping paper. The mainstream smoke or aerosol generated in themedium portion 130 may contain a wetting agent, moisture, other compounds, and the like. - That is, since the
wrapper 136 may be stained or weakened due to the additives added to the smoking material portions in the process in which themedium portion 130 is combusted, a coating layer for grease resistance or water resistance may be imparted to a surface of thewrapper 136. - The coating layer may consist of at least one of silicone materials, wax materials, and natural materials. For example, the wax materials may correspond to one of paraffin wax, embed, crystal palm, multiwax, carnauba wax, candelia wax, castor wax, microcrystalline wax, gel wax, beeswax, stearic acid, polypropylene wax, polyethylene wax, and polyethylene acrylic wax or a combination of at least two of the above-listed materials, but are not limited thereto.
- Also, the silicone materials may be liquid silicone, but are not limited thereto. In addition, natural material fibers may be flax, but are not limited thereto. The flax has a characteristic in that the strength of the flax increases when the flax absorbs moisture. Thus, the flax may improve the water resistance of the
wrapper 136. - As another example, the coating layer may consist of fine particles. Here, the fine particles may be microcapsules in which the silicone materials or wax materials are formed as a matrix. For example, in the fine particles, a waterproof nanoprotrusion structure may be firstly coated with methyl cellulose acetate to reinforce strength and secondly coated with a wax such as paraffin wax to strengthen the physical properties of powder. Therefore, the coating layer including the fine particles may improve the water resistance of the
wrapper 136. -
FIG. 6 is a longitudinal cross-sectional view of a smoking article including a multilayer medium portion according to an embodiment of the present invention. - The case in which the smoking article is a conventional cigarette will be described as an example with reference to
FIG. 6 . - Referring to
FIG. 6 , the firstsmoking material portion 132 and the secondsmoking material portion 134 are disposed in the longitudinal direction of themedium portion 130, and the firstsmoking material portion 132 is surrounded by the secondsmoking material portion 134. - The aerosols generated in the first
smoking material portion 132 and the secondsmoking material portion 134 move in the downstream direction and are delivered to the smoker through thefilter portion 110. In this case, since the tobacco raw materials included in the firstsmoking material portion 132 and the tobacco raw materials included in the secondsmoking material portion 134 are different, components of the aerosols generated in the smoking material portions may also be different. Therefore, the smoker may taste various tobacco flavors in one smoking article. - Meanwhile, the amount of aerosol generated in the first
smoking material portion 132 and the amount of aerosol generated in the secondsmoking material portion 134 may have to be different to enhance the tobacco flavor in some cases. For example, there may be case in which the tobacco flavor is further enhanced when the amount of aerosol generated in the firstsmoking material portion 132 is larger than the amount of aerosol generated in the secondsmoking material portion 134. - To this end, the resistance to draw (RTD) of the first
smoking material portion 132 and the RTD of the secondsmoking material portion 134 may be made different. This is because, when the smoker puffs thesmoking article 100 with a constant force, the aerosol generated in the smoking material portion with a relatively higher RTD is introduced into thefilter portion 110 in a smaller amount than the aerosol generated in the smoking material portion with a relatively lower RTD, and as a result, the mixed amount of aerosol originating from each smoking material portion may be adjusted. - The RTD of the smoking material portion may be determined by various factors.
- In one example, each smoking material portion is implemented in a form in which tobacco raw materials are packed therein, and the RTD of each smoking material portion may be adjusted by varying the packing density. Thus, according to an embodiment of the present invention, a packing density of the tobacco raw materials included in the first
smoking material portion 132 and a packing density of the tobacco raw materials included in the secondsmoking material portion 134 may be different. - In another example, the tobacco raw materials included in each smoking material portion may be processed into the form of strands and then packed in the smoking material portion. When the tobacco strands are packed to be parallel to each other in the longitudinal direction of the
medium portion 130, air passages may be formed in the smoking material portions and movement of the aerosols is facilitated. On the other hand, when the tobacco strands are packed in random arrays, movement of the stream of aerosols is not facilitated, and thus the RTD relatively increases. - Accordingly, the tobacco strands included in one of the first
smoking material portion 132 and the secondsmoking material portion 134 may be packed to be parallel to each other in the longitudinal direction of themedium portion 130, and the tobacco strands included in the other one may be packed in random arrays. - According to the
smoking article 100 according to an embodiment of the present invention, it is possible to achieve the effect of allowing the user to taste various tobacco flavors in thesmoking article 100. -
FIG. 7 is a view illustrating an example in which a smoking article according to an embodiment of the present invention is used by being inserted into an aerosol generation device. - Referring to
FIG. 7 , anaerosol generation device 200 may include a battery (not illustrated), a controller (not illustrated), and aheater 210. According to an embodiment of the present invention, the battery, controller, and heater constituting theaerosol generation device 200 may be arranged in a row, but the arrangement structure is not limited thereto. Theaerosol generation device 200 may, of course, further include general-purpose elements other than those mentioned above. - The battery supplies power used to operate the
aerosol generation device 200. For example, the battery may supply power to allow the heater to be heated and supply power required for operation of the controller. Also, the battery may supply power required for operation of a display, a sensor, a motor, and the like installed in theaerosol generation device 200. - The controller may control the overall operation of the
aerosol generation device 200. Specifically, the controller may check the states of not only the battery and the heater but also other components of theaerosol generation device 200 and determine whether theaerosol generation device 200 is in an operable state. - The controller may include at least one processor. The processor may be implemented with an array of a plurality of logic gates or implemented with a combination of a general-purpose microprocessor and a memory which stores a program that may be executed by the microprocessor. Also, those of ordinary skill in the art to which the present embodiment pertains should understand that the controller may also be implemented with other forms of hardware.
- The
heater 210 may be heated by the power supplied from the battery. Theheater 210 according to an embodiment of the present invention may be an electrically-resistive heater including an electrically-conductive track and may be heated as current is applied. In another embodiment, the heater 10 may be implemented as an induction heating-type heater. In this case, theheater 210 may include an electrically-conductive coil. - The case in which the
heater 210 is a needle-shaped or rod-shaped heating element is illustrated as an example inFIG. 7 , but the shape of theheater 210 is not limited thereto, and theheater 210 may, of course, be implemented in various other shapes such as a plate shape. - In the case in which the
smoking article 100 according to an embodiment of the present invention is inserted into theaerosol generation device 200, the entiremedium portion 130 may be inserted into theaerosol generation device 200 and thefilter portion 110 may be exposed to the outside. Alternatively, a portion of thefilter portion 110 may be inserted with themedium portion 130, or only a portion of themedium portion 130 may be inserted. - The smoker may, while holding the
filter portion 110 in his or her mouth, inhale the aerosols generated in the firstsmoking material portion 132 and the secondsmoking material portion 134 of themedium portion 130. - In one example, outside air may be introduced through at least one air passage formed in the
aerosol generation device 200. For example, the opening/closing state of the air passage formed in theaerosol generation device 200 or the size of the air passage may be adjusted by the smoker. Accordingly, vapor production, smoking sensation, and the like may be adjusted by the user. In another example, outside air may be introduced into thesmoking article 100 through at least one air hole (not illustrated) formed in a surface of thesmoking article 100. - In the case in which the
smoking article 100 according to an embodiment of the present invention is used by being inserted into the internal heating-typeaerosol generation device 200 illustrated inFIG. 7 , the firstsmoking material portion 132 disposed inside themedium portion 130 is heated first, and an aerosol is intensively generated from the firstsmoking material portion 132. Consequently, the smoker may taste a tobacco flavor from the aerosol generated in the firstsmoking material portion 132 in an early stage of smoking. - As the smoking time elapses, the heat generated by the
heater 210 diffuses from the center of themedium portion 130 toward an outer side surface thereof, and thus an aerosol is generated in the secondsmoking material portion 134. Consequently, the smoker may taste a tobacco flavor originating from the secondsmoking material portion 134 in a later stage of smoking. -
FIG. 8 is a view illustrating another example in which a smoking article according to an embodiment of the present invention is used by being inserted into an aerosol generation device. - Referring to
FIG. 8 , anaerosol generation device 200 may include a battery (not illustrated), a controller (not illustrated), a vaporizer (not illustrated), and aheater 210. - Since the battery and the controller are identical to those described above with reference to
FIG. 7 , descriptions thereof will be omitted to avoid repeated description. - The
heater 210 may be disposed along an outer side surface inside an insertion hole formed in a cylindrical shape at one surface of theaerosol generation device 200. When thesmoking article 100 according to an embodiment of the present invention is inserted into the insertion hole, theheater 210 is operated and performs heating from an outer side surface of thesmoking article 100. - Therefore, the second
smoking material portion 134 disposed at an outer side of themedium portion 130 is heated first, and an aerosol is intensively generated from the secondsmoking material portion 134. Consequently, the smoker may taste a tobacco flavor from the aerosol generated in the secondsmoking material portion 134 in an early stage of smoking. - As the smoking time elapses, the heat generated by the
heater 210 diffuses in an inward direction from the outer side surface of themedium portion 130, and thus the firstsmoking material portion 132 is heated to generate an aerosol. Consequently, the smoker may taste a tobacco flavor originating from the firstsmoking material portion 132 in a later stage of smoking. - Alternatively, the smoker may taste a tobacco flavor that is generated as the aerosol generated in the first
smoking material portion 132 and the aerosol generated in the secondsmoking material portion 134 are mixed. In this case, as the smoking time elapses, the amount of aerosol generated in the secondsmoking material portion 134 gradually decreases while the amount of aerosol generated in the firstsmoking material portion 132 gradually increases. Consequently, the smoker may taste various tobacco flavors. - Those of ordinary skill in the art related to the present embodiments should understand that the present invention may be implemented in modified forms within the scope not departing from essential characteristics of the above description. Therefore, the methods disclosed herein should be considered as illustrative rather than limiting. The scope of the present invention is defined by the claims below rather than by the above description, and all differences within the scope equivalent to the claims should be interpreted as falling within the scope of the present invention.
