Description

The present disclosure relates to aerosol-generating articles and aerosol-generating devices.

Recently, there has been an increasing demand for alternative methods that overcome the shortcomings of common cigarettes. One alternative method to overcome the disadvantages of cigarettes is a hybrid aerosol generation system that uses both cartridges and cigarettes.

A hybrid type aerosol generation system is a system that smokes aerosol generated by heating a cigarette and aerosol flowing into the cigarette from the outside.

Hybrid aerosol generation systems generate most of the aerosol that is smoked mechanically directly from the cartridge. The hybrid type aerosol generation system has the advantage of almost no peculiar unpleasant odor generated during the process of heating or steaming cigarettes, has the advantage of a large amount of atomization, and has the advantage of providing the smoking sensation of traditional cigarettes. .

To increase the amount of atomization, most of the aerosol that is smoked is generated mechanically directly from the cartridge, so a hybrid type aerosol generation system is a process in which the mechanically generated aerosol passes through the inside of the cigarette. An important factor in increasing the amount of atomization is to filter as little as possible.

However, in the conventional hybrid type aerosol generation system, a considerable amount of the mechanically generated aerosol is filtered by the tobacco leaves while passing through the cigarette, resulting in a large reduction in the amount of atomization.

In order to solve the above problems, various embodiments provide an aerosol generating article and an aerosol generating device having a structure that can generate a large amount of atomization.

According to one embodiment, a tobacco rod, a front end plug disposed on one side of the tobacco rod, a filter rod disposed on the other side of the tobacco rod, and a filter rod disposed inside the tobacco rod, the front end plug disposed on one side of the tobacco rod; An aerosol generating article can be provided that includes a moving aerosol transfer tube.

As described above, the aerosol generating article and the aerosol generating device according to one aspect of the present disclosure can prevent the amount of atomization from greatly decreasing while the aerosol passes through the inside of the tobacco rod.

Therefore, the user can experience a rich amount of atomization as well as the unique taste and aroma of rolled tobacco.

FIG. 1 is a schematic perspective view of an exposed aerosol-generating article according to a first embodiment of the present disclosure, FIG. 2 is a variation of the front end plug of the first embodiment of the present disclosure, and FIG. 4 is a cross-sectional view of an aerosol-generating article according to a first embodiment of the present disclosure, taken along line BB in FIG. 3; FIG.

Referring to FIGS. 1-4, an aerosol-generating article 100 according to a first embodiment of the present disclosure may include a front end plug 110, a tobacco rod 130, a filter rod 150, an aerosol transfer tube 160, and a wrapper 170. Here, it should be noted that other general-purpose components other than those shown in FIGS. Anyone with knowledge can understand it.

The aerosol generating article 100 according to this example may be inserted into an aerosol generating device 300 (see FIGS. 18 and 19) to be described later and heated. At this time, when the aerosol generating article 100 is heated, mainstream smoke is transmitted to the user. Mainstream smoke is an airflow that flows from upstream to downstream within the aerosol-generating article 100. Here, upstream means the front end plug 110 side, and downstream means the filter rod 150 side. A user of the aerosol-generating article 100 can inhale mainstream smoke through the downstream end of the aerosol-generating article 100.

Aerosol generating article 100 may be formed into a cylindrical shape. Here, the diameter of the aerosol generating article 100 may be 4.7 mm to 9.9 mm. The front end plug 110, tobacco rod 130 and filter rod 150 may also be cylindrical with a diameter of 4.7 mm to 9.9 mm.

Additionally, aerosol generating article 100 may have a length of 35 mm to 60 mm. The length of the front end plug 110 may be between 4 mm and 9 mm. Tobacco rod 130 may have a length of 12 mm to 19 mm, and filter rod 150 may have a length of 19 mm to 32 mm.

Numerical values for the shapes, diameters, and lengths of the aerosol-generating article 100 and components are illustrated, but are not necessarily limited thereto. The formation and dimensions of the aerosol generating article 100 may vary within the skill of those skilled in the art.

The front end plug 110 is located at the upstream end of the aerosol-generating article 100 and can prevent the tobacco rod 130 from detaching from the aerosol-generating article 100. The front end plug 110 may be located at an upstream end of the tobacco rod 130 facing the filter rod 150 with the tobacco rod 130 at the center.

The front end plug 110 prevents impurities from flowing into the tobacco rod 130 from the outside, and prevents aerosol liquefied during smoking from flowing into the aerosol generating device 300 (see FIGS. 18 and 19).

Additionally, when the aerosol generating article 100 is inserted into the aerosol generating device 300, the front end plug 110 can support the aerosol generating article 100 so that the aerosol generating article 100 is fixed to the aerosol generating device 300.

The front end plug 110 may include a crimped sheet (not shown). Here, the crimped sheet may be a sheet made of a polymeric material. For example, the polymeric material may include at least one of paper, cellulose acetate, lyocell, and polylactic acid. However, the polymeric material is not necessarily limited to this, and may not include a crimped sheet depending on the front end plug structure.

The crimped sheet of the front end plug 110 may be impregnated with an aerosol product quality described below. Other additives such as flavoring agents, humectants, and/or organic acids and perfuming liquids may also be included in the front end plug 110 while being absorbed into the crimped sheet.

The aerosol product quality included in the front end plug 110 may exclude nicotine. For example, front end plug 110 includes at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. However, the quality of the aerosol product contained in the front end plug 110 is not necessarily limited thereto. For example, the front end plug 110 may include a mixture of glycerin and propylene glycol in a ratio of about 8:2. However, the mixing ratio is not limited to the above-mentioned mixing ratio.

The front end plug 110 may be a cellulose acetate filter. For example, the front end plug 110 may be made from cellulose acetate tow with a plasticizer, such as triacetin. The cellulose acetate tow may also include the aforementioned aerosol product qualities. As well, other additive substances such as flavoring agents, humectants and/or organic acids may be included. However, the material and type of the front end plug 110 are not necessarily limited thereto, and can be changed within the range that can be adopted by those skilled in the art.

In some embodiments, depending on the material of the front end plug 110, the front end plug 110 may be formed with a hole 111 through which aerosol flows from the outside to form mainstream smoke inside the aerosol generating article 100. . For example, when the front end plug 110 includes cellulose acetate tow, a through hole 111 is formed in the front end plug 110, as shown in FIG. Here, the through hole 111 may have a circular or Y-shaped cross-section, but the cross-sectional shape of the through hole is not necessarily limited thereto, and may have various cross-sectional shapes.

In some embodiments, if the front end plug 110 includes a crimped sheet impregnated with an aerosol product quality, the front end plug 110 may not have a through hole formed therein, as shown in FIG. 1 .

At this time, when a part of the aerosol generating article 100 is inserted into the aerosol generating device 300, the aerosol generated from the aerosol generating device 300 flows into the aerosol generating article 100 through the front end plug 110, and the aerosol is Mainstream smoke can be formed within the aerosol-generating article 100 and transmitted to the user. Also, the aerosol generated inside the front end plug 110 containing the aerosol product quality may form mainstream smoke and be transmitted to the user.

Furthermore, a heating section 370 (see FIG. 19) of the aerosol generating device 300 that heats the aerosol generating article 100 may be inserted into the through hole of the front end plug 110. Although heating portion 370 is shown in FIG. 19 as being disposed around aerosol generating article 100, this disclosure is not limiting. For example, the heater 370 may have a shape corresponding to the through hole 111 of the front end plug 110 and be inserted into the through hole 111 .

Front end plug 110 may further include configuration for identifying aerosol generating article 100. The aerosol-generating article 100 can exhibit various tastes, aromas, etc., and may include a configuration for distinguishing these various types of aerosol-generating articles 100 from each other. For example, the front end plug 110 may include a metal foil for changing the inductance of a coil included in the aerosol generating device 300 to identify the type of aerosol generating article. However, the invention is not necessarily limited thereto, and a structure for identifying the aerosol-generating article 100 may be included in the tobacco rod 130 in addition to the front end plug 110.

Tobacco rod 130, located between front end plug 110 and filter rod 150, may include an aerosol-generating tobacco medium 131. As the aerosol that has entered the tobacco rod 130 passes through the tobacco rod 130, the taste and aroma unique to rolled tobacco can be incorporated into the aerosol. More specifically, the tobacco medium of tobacco rod 130 can contain nicotine. As a result, nicotine is mixed into the aerosol in the process of the aerosol passing through the tobacco rod 130, allowing the user smoking mainstream smoke to experience the unique taste and aroma of a rolled cigarette.

For example, the nicotine may be one or more of free base nicotine or nicotine salt, and the nicotine may be naturally occurring nicotine or synthetic nicotine. good.

Nicotine salts are formed by adding a suitable acid, including organic or inorganic acids, to nicotine. The acid for forming the nicotine salt is appropriately selected in consideration of the nicotine absorption rate in the blood, the heating temperature of the heater, the flavor, the solubility, and the like. For example, acids for the formation of nicotine salts include benzoic acid, lactic acid, salicylic acid, lauric acid, sorbic acid, levulinic acid, pyruvic acid, formic acid, acetic acid, propionic acid, butyric acid, valeric acid, caproic acid, caprylic acid, Composed of capric acid, citric acid, myristic acid, palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid, phenylacetic acid, tartaric acid, succinic acid, fumaric acid, gluconic acid, saccharic acid, malonic acid or malic acid It may be a single acid selected from the group or a mixture of two or more acids selected from the group, but is not limited thereto.

Meanwhile, the tobacco medium of the tobacco medium part 110 can be manufactured in various forms. For example, the tobacco medium may be made in sheets or in strands. Further, the tobacco medium 131 may be made of shredded tobacco obtained by cutting a tobacco sheet. Additionally, the tobacco medium 131 may be made in the form of granules containing tobacco.

Tobacco rod 130 may be formed in a cylindrical shape. However, the shape of the tobacco rod 130 is not limited thereto, and may be formed into a bar shape having various cross-sections.

Here, the tobacco rod 130 may be fabricated into a cylindrical shape by folding a tobacco sheet, or may be fabricated by forming tobacco strands, shredded tobacco, or tobacco granules into a cylindrical shape.

When the tobacco rod 130 is made of a plurality of tobacco strands obtained by cutting a tobacco sheet into pieces, the tobacco rod 130 may be formed by combining the plurality of tobacco strands in the same direction (parallel) or randomly. Specifically, the tobacco rod 130 may be formed by combining a plurality of tobacco strands to form a plurality of longitudinal channels through which aerosol can pass. Here, depending on the size and arrangement of the tobacco strands, the longitudinal channels are uniform or non-uniform.

Tobacco rod 130 may further include aerosol product qualities to increase the amount of atomization. For example, the aerosol product quality may include, but is not limited to, at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol.

Tobacco rod 130 may further include flavoring substances to add flavor to the aerosol produced from the tobacco rod. For example, tobacco rod 130 may include other additives such as flavoring agents, humectants, and/or organic acids. Further, a flavoring liquid such as menthol or a humectant can be added to the tobacco rod 130 by spraying it onto the tobacco rod 130.

Here, the flavoring agents are licorice, sucrose, fructose syrup, isosweet, cocoa, lavender, cinnamon, cardamom, celery, fenugreek, cascarilla, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon. It may include oil, orange oil, mint oil, cinnamon, caraway, cognac, jasmine, chamomile, menthol, cinnamon, ylang-ylang, salvia, spearmint, ginger, coriander or coffee. Wetting agents may also include glycerin, propylene glycol, and the like.

Tobacco rod 130 may be wrapped in a thermally conductive material. The thermally conductive material can evenly disperse heat transferred to the tobacco rod 130 and improve the thermal conductivity transferred to the tobacco rod 130, thereby improving the taste of the tobacco. The thermally conductive material may be a metal foil, for example the thermally conductive material may be aluminum. However, the heat conductive material is not necessarily limited to this, and various materials that can be used as heat conductive materials can be used.

Filter rod 150 may be located at the downstream end of aerosol-generating article 100 to cool mainstream smoke containing aerosols or to filter substances contained in the mainstream smoke. The filter rod 150 may be located at the downstream end of the tobacco rod 130 facing the front end plug 110 with the tobacco rod 130 at the center.

Filter rod 150 may consist of a single segment or multiple segments. Although the aerosol generating article 100 of FIGS. 1-4 is shown as a single segment, it is not necessarily so limited and may be comprised of multiple segments. For example, when the filter rod 150 is comprised of a plurality of segments, the filter rod 150 includes a segment that cools the aerosol and a segment that filters substances contained in the aerosol generated from the tobacco rod. Additionally, filter rod 150 may further include segments that perform other functions as needed.

If filter rod 150 includes aerosol cooling segments, such segments may be made of polymeric or biodegradable polymeric materials. Here, the polymeric material includes, but is not limited to, gelatin, polyethylene (PE), polypropylene (PP), polyurethane (PU), fluorinated ethylene propylene (FEP), and combinations thereof. In addition, biodegradable polymer substances include polylactic acid (PLA), polyhydroxybutyrate (PHB), cellulose acetate, polyepsilon caprolactone (PCL), polyglycolic acid (PGA), polyhydroxyalkanoates (PHAs), and These include, but are not limited to, starch-based thermoplastic resins.

Additionally, if the filter rod 150 includes segments that filter substances, such segments may be of the same configuration as the front end plug 110 described above. For example, the filter rod 150 may be a cellulose acetate filter, and may be made by adding a plasticizer such as triacetin to cellulose acetate tow. However, the material and type of the segments are not necessarily limited to these, and can be changed within the range that can be adopted by those skilled in the art.

The filter rod 150 may be formed in various shapes. For example, the filter rod 150 may be a cylindrical rod or may be a tubular rod with a hollow inside. Additionally, the filter rod 150 may be a recess type rod. Here, when the filter rod 150 includes a plurality of segments, each of the plurality of segments may have a different shape.

Filter rod 150 can also be fabricated to generate a flavor. For example, a perfumed liquid may be sprayed onto the filter rod 150, and a separate fiber to which the perfumed liquid is applied may be included inside the filter rod 150.

Alternatively, filter rod 150 may include at least one capsule (not shown). Capsules can be flavor-producing or aerosol-producing. For example, a capsule may be structured to enclose a liquid containing a flavor or taste. Here, the capsule may have a spherical or cylindrical shape, but the shape of the capsule is not necessarily limited to this.

According to this embodiment, the aerosol transfer tube 160 is disposed inside the tobacco rod 130, so that the aerosol flowing into the aerosol transfer tube 160 can be directly transferred from the front end plug 110 to the filter rod 150.

Specifically, the aerosol transfer pipe 160 can directly transfer a portion of the aerosol A that has entered from the outside from the front end plug 110 to the filter rod 150 without passing through the tobacco medium 131 of the tobacco rod 130. Here, "aerosol flowing in from the outside" means not an aerosol generated inside the aerosol generating article 100 but an aerosol generated by the aerosol generating device 300 (see FIGS. 18 and 19). Further, the aerosol transfer pipe 160 can directly transfer a part of the aerosol generated inside the front end plug 110 from the front end plug 110 to the filter rod 150 without passing through the tobacco medium 131 of the tobacco rod 130. That is, the aerosol transfer pipe 160 can transfer not only the aerosol A that has flowed in from the outside, but also the aerosol that has been generated inside the front end plug 110 .

The aerosol transfer tube 160 is located inside the tobacco rod 130, and the inlet of the aerosol transfer tube 160 faces the front end plug 110, and the outlet of the aerosol transfer tube 160 faces the filter rod 150. may be done. Here, the inlet of the aerosol transfer pipe 160 is where the aerosol flows in, and the outlet of the aerosol transfer pipe 160 is where the aerosol flows out.

In this embodiment, as long as the inlet and outlet of the aerosol transfer tube 160 are arranged only in the above-described manner, the middle section of the aerosol transfer tube 160 may be arranged in various shapes. For example, the intermediate section of the aerosol transfer tube 160 may be arranged in a straight line (see FIG. 3), bent (see FIG. 17), meandering, or inclined. It may take various forms, such as being arranged in a different form. That is, as long as the inlet and outlet of the aerosol transfer tube 160 are directed toward the front end plug 110 and the filter rod 150, respectively, the intermediate section of the aerosol transfer tube 160 can have any shape. However, as shown in FIG. 3, the aerosol transfer tube 160 may be formed in a straight line parallel to the extending direction of the tobacco rod 130.

Here, the inlet of the aerosol transfer tube 160 may be located at a portion where the front end plug 110 and the tobacco rod 130 are in contact, and the outlet of the aerosol transfer tube 160 may be located at a portion where the tobacco rod 130 and the filter rod 150 are in contact. More specifically, the inlet and outlet of the aerosol transfer tube 160 may be located at both ends of the tobacco rod 130.

At least one aerosol transfer pipe 160 is disposed inside the tobacco rod 130. As shown in FIG. 4, one aerosol transfer tube 160 is disposed inside the tobacco rod 130, or as in an additional embodiment shown in FIG. Placed. Here, the plurality of aerosol transfer pipes 160 may have the same diameter or different diameters.

When one aerosol transfer tube 160 is disposed inside the tobacco rod 130, the aerosol transfer tube 160 may be disposed at the center of the tobacco rod 130 so that the aerosol is smoothly transferred.

Aerosol transfer tube 160 can have a variety of cross-sectional shapes. For example, the aerosol transfer tube 160 can have a circular cross section, a polygonal cross section, a Y-shaped cross section, etc.

The aerosol transfer tube 160 may be made of various materials such as paper, metal, fabric, and plastic. For example, for metals, aluminum may be used, and for plastics, thermosetting plastics may be used. However, the material of the aerosol transfer tube 160 is not necessarily limited to this.

Regarding the size of the aerosol transfer tube 160, the volume of the aerosol transfer tube 160 can be provided in percentages within a predetermined percentage range relative to the volume of the tobacco rod 130. Specifically, the volume occupied by the aerosol transfer tube 160 may be 10 to 90 volume percent (%) of the total volume of the tobacco rod 130. If the volume occupied by the aerosol transfer tube 160 is less than 10 volume percent (%), a sufficient amount of atomization cannot be expected because the amount of aerosol directly transferred through the aerosol transfer tube 160 is not sufficient. In addition, if the volume occupied by the aerosol transfer pipe 160 exceeds 90 volume percent (%), a large amount of atomization flows out to the outside, but enough of the aerosol passes through the tobacco rod 130 and retains the unique taste and aroma of rolled tobacco. may not be included.

The aerosol that has entered the tobacco rod 130 passes through the tobacco rod 130, and a considerable amount of the aerosol is filtered by the tobacco medium 131 inside the tobacco rod 130, and a mist is passed through the filter rod 150 and discharged to the outside. There is a possibility that the amount of oxidation may be significantly reduced. However, according to this embodiment, at least a portion of the aerosol can directly pass through the filter rod 150 via the aerosol transfer pipe 160 without passing through the tobacco medium 131 and be discharged to the outside. Therefore, it is possible to prevent the amount of atomization from decreasing while the aerosol passes through the aerosol generating article 100. In addition, this allows a user who smokes mainstream smoke to enjoy the rich atomization amount as well as the taste and aroma unique to rolled cigarettes.

In addition, in this embodiment, the inlet and outlet of the aerosol transfer pipe 160 correspond to the ends of the tobacco rod 130, so that the aerosol passes smoothly without passing between the tobacco media 131 of the tobacco rod 130, resulting in a rich mist. can provide a large amount of

Meanwhile, a modification of the aerosol transfer pipe 160 according to the first embodiment of the present disclosure will be described with reference to FIGS. 6 to 8. The aerosol transfer tubes 160A, 160B, and 160C of FIGS. 6 to 8 are located within the tobacco rod 130, and at least one of the inlet and outlet of the aerosol transfer tubes 160A, 160B, and 160C corresponds to the end of the tobacco rod 130. Sometimes I don't.

Referring to FIG. 6, the inlet and outlet of aerosol transfer tube 160A are both spaced from the end of tobacco rod 130. The aerosol transfer tube 160A is located inside the tobacco rod 130, but since the inlet and outlet of the aerosol transfer tube 160A do not correspond to the ends of the tobacco rod 130, a portion of the aerosol is transferred along the aerosol transfer tube 160A. A tobacco medium 131 may be passed through the section.

Further, the outlet of the aerosol transfer tube 160B in FIG. 7 does not overlap with the end of the tobacco rod 130, and the inlet of the aerosol transfer tube 160C in FIG. 8 does not overlap with the end of the tobacco rod 130. Accordingly, the aerosol transferred along the aerosol transfer pipes 160B and 160C may pass through the tobacco medium 131 in some sections.

A wrapper 170 can wrap the aerosol-generating article 100. At least one perforation (not shown) may be formed in the wrapper 170 to allow external air to enter or internal air to exit the aerosol-generating article 100. Aerosol-generating article 100 can be packaged with a single wrapper, or can be wrapped with multiple wrappers in an overlapping or multiple manner.

Tobacco rod 130 and filter rod 150 may be individually wrapped in separate wrappers. If tobacco rod 130 and filter rod 150 are individually packaged, the individually packaged arrangement can also be repackaged as a whole with another wrapper.

Below, an aerosol generating article according to a second embodiment of the present disclosure and a modification thereof will be described.

FIG. 9 is a cross-sectional view of an aerosol generating article according to a second embodiment of the present disclosure, and FIGS. 10 to 12 are modified examples of the aerosol transfer tube according to the second embodiment of the present disclosure.

Explaining with reference to FIG. 9, the aerosol generating article according to the second embodiment has the same structure as the aerosol generating article 100 according to the first embodiment except for the aerosol transfer pipe 161, so the aerosol generating article according to the second embodiment has the same structure. Duplicate explanations will be omitted.

According to this embodiment, as shown in FIG. 9, the aerosol transfer pipe 161 is not only disposed within the tobacco rod 130, but also may be extended into the front end plug 110. Here, the inlet of the aerosol transfer tube 161 may correspond to the upstream end of the front end plug 110, and the outlet of the aerosol transfer tube 161 may correspond to the downstream of the tobacco rod 130.

Thereby, a part of the aerosol A flowing in from the outside can directly move along the aerosol transfer pipe 161 without passing through the inside of the front end plug 110. Therefore, the reduction of aerosol during the process of passing through the front end plug 110 can be further reduced.

Meanwhile, a modification of the aerosol transfer pipe 161 according to the second embodiment of the present disclosure will be described with reference to FIGS. 10 to 12. The aerosol transfer pipes 161A, 161B, 161C in FIGS. 10 to 12 extend to the front end plug 110, and at least one of the inlets or outlets of the aerosol transfer pipes 161A, 161B, 161C) is at the upstream end of the front end plug 110, respectively. The downstream end of the tobacco rod 130 may not correspond to the downstream end of the tobacco rod 130.

Referring to FIG. 10, the inlet of the aerosol transfer tube 161A is separated from the upstream end of the front end plug 110. In FIG. 11, the inlet and outlet of aerosol transfer tube 161B do not correspond to the upstream end of front end plug 110 and the downstream end of tobacco rod 130, respectively. Further, in FIG. 12, the outlet of the aerosol transfer pipe 161C is separated from the right end of the tobacco rod 130 without overlapping with it.

Below, an aerosol generating article according to a third embodiment of the present disclosure and a modification thereof will be described.

FIG. 13 is a cross-sectional view of an aerosol generating article according to a third embodiment of the present disclosure, and FIGS. 14 to 16 are modified examples of the aerosol transfer tube according to the third embodiment of the present disclosure.

Referring to FIG. 13, the aerosol-generating article according to the third embodiment has the same structure as the aerosol-generating article 100 according to the first embodiment except for the aerosol transfer pipe 166. Duplicate explanation regarding the configuration will be omitted.

According to this embodiment, as shown in FIG. 13, the aerosol transfer tube 166 is not only disposed within the tobacco rod 130 but also extends inside the filter rod 150. Here, the inlet of the aerosol transfer tube 166 corresponds to the upstream end of the tobacco rod 130, and the outlet of the aerosol transfer tube 166 is located inside the filter rod 150.
