Description

The present invention relates to an electronic smokeless cigarette to which a scented sheet is applied.

In recent years, there has been an increasing demand for alternative articles that overcome the shortcomings of traditional cigarettes. For example, there is an increasing demand for devices that generate an aerosol by electrically heating a cigarette stick (eg, cigarette-type electronic cigarettes). Accordingly, research into electrically heated aerosol generators and cigarette sticks (or aerosol-generating articles) applied thereto is actively progressing.

On the other hand, if no visible smoke is generated during smoking, there is an advantage that the user can enjoy smoking without being restricted by the place or environment. In addition, due to these advantages, smokeless tobacco products such as snuff, snus, and chewing tobacco have been developed. However, the exemplified smokeless tobacco products have the disadvantage of not being able to provide the smoking feel of a combustible cigarette or a heated cigarette stick.

On the other hand, the heat-not-burn smokeless tobacco lacks the amount of aerosol that can smoothly transfer the scent, so the conventional TJNS (Trans jet nozzle system) or scent capsule application method is not sufficient to transfer the scent. This is because, due to lack of aerosol, the designed herb is crushed or the desired level of fragrance intensity cannot be transferred.

In particular, in order to provide a custom-made smoking experience due to the recent diversification of user preferences, crushed scent capsules are added to the filter to provide flavor. Depending on whether or not it can be crushed, it is possible to provide a general flavor to the user by including the perfume inside, or it is possible to provide an enhanced flavor to the user. There is also a disadvantage that the expression of flavor decreases toward the latter half, and that it is not possible to provide a precise control function for flavor intensity. A TJNS (Trans jet nozzle system) filter can also be used, but it also has the disadvantage of not being able to provide precise control over flavor intensity.

Another technical problem to be solved through some embodiments of the present invention is to provide an aerosol-generating article that can be used with an aerosol-generating device with smokeless functionality.

Yet another technical problem to be solved through some embodiments of the present invention is to provide an aerosol-generating article that can impart a rich flavor.

The technical problems of the present invention are not limited to the technical problems mentioned above. Other technical problems not mentioned can be clearly understood by those skilled in the art in the technical field of the present invention from the following description.

According to the first aspect of the present invention,

In one embodiment of the present invention, the tobacco rod includes a filter segment and a cavity segment, and one or more of the filter segment and the cavity segment may contain a flavoring agent.

In one embodiment of the invention, said filter segment comprises a first filter segment and a second filter segment, said first filter segment being downstream of said cavity segment and said second filter segment being located downstream of said cavity segment. Located upstream, the cavity segment can be formed by the first filter segment and the second filter segment.

In one embodiment of the invention, the filter rod can include a cooling segment and a mouthpiece segment.

In one embodiment of the present invention, the flavor source is one or more selected from the group consisting of flavored sheets, flavored granules and TJNS filters.

In one embodiment of the present invention, the cavity segment may include at least one of scented granules and scented sheets.

In one embodiment of the present invention, the filter segment may include any one or more of TJNS filter and scented sheet.

In one embodiment of the present invention, the aerosol generator may include a heater for externally heating the tobacco rod.

In one embodiment of the present invention, the aerosol generator may include a heater section for externally heating the cavity segment.

In one specific example of the present invention, the aerosol generator includes a heater section for heating the cavity segment; and a portion of any one of the first filter segment and the second filter segment in contact with the cavity segment. can contain.

According to some embodiments of the invention described above, an aerosol-generating article suitable for implementing smokeless functionality of an aerosol-generating device can be provided. Specifically, provided aerosol-generating articles comprise a tobacco rod having a cavity filled with tobacco granules, wherein the tobacco granules are cut tobacco (eg leaf tobacco cut tobacco, flat leaf cut tobacco), flat tobacco Due to the significantly lower content of moisture and/or aerosol-forming agents compared to tobacco materials such as leaves, visible smoke generation can be greatly reduced. In addition, since the tobacco granules exhibit sufficient smoking taste even at a relatively low temperature compared to other types of tobacco materials, the heating temperature of the aerosol generator can be set relatively low. This allows the generation of visible smoke to be further reduced.

In addition, a scented sheet, scented granules, or TJNS filter is included in the cavity or filter segment, and when heated, the scent intensity and scent persistence are remarkably increased, and the offensive odor is reduced. be.

Also, by providing the smokeless function, the user can use the aerosol generator without being restricted by location or environment. Accordingly, user convenience can be improved.

Also, a cavity segment can be formed by filter segments positioned upstream and downstream of the tobacco rod, and tobacco granules can be filled in the cavity segment. Accordingly, a tobacco rod can be easily manufactured in which the falling-off phenomenon of tobacco granules can be minimized.

Also, the filter segments forming the cavity segments of the tobacco rod can consist of paper filters. In such a case, it is possible to prevent the problem that the physical properties of the filter segment change due to the heating of the heater section.

Also, the tobacco rod can be designed to create vortices inside the cavity segments during the pouf. In this case, since the tobacco granules are well mixed and heated by the generated swirling airflow, a large number of tobacco granules can be uniformly heated, and the smoking taste can be further improved.

Various embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

FIG. 1 is an exemplary drawing for explaining an aerosol generator 1 according to some embodiments of the invention. In particular, FIG. 1 and subsequent drawings show the state in which the aerosol-generating article 2 is inserted (contained) as an example.

As shown in FIG. 1, an aerosol generator 1 according to an embodiment of the present invention may include a housing, a heater section 13, a battery 11 and a control section 12. As shown in FIG. However, FIG. 1 shows only the components related to the embodiment of the present invention. Accordingly, a person of ordinary skill in the technical field to which the present disclosure pertains will appreciate that general-purpose components can be further included in addition to the components shown in FIG. For example, the aerosol generator 1 has an input module (eg button, touchable display, etc.) for receiving commands from the user, and an input module for outputting information such as the state of the device and smoking information. Output modules (eg LEDs, displays, vibration motors, etc.) may also be included. Each component of the aerosol generator 1 will be described below.

A housing according to embodiments of the present invention can form the exterior of the aerosol generator 1 . The housing can also form a containment space for containing the aerosol-generating article 2 . The housing is preferably implemented with a material capable of protecting internal components.

Next, the heater unit 13 according to the embodiment of the present invention can heat the aerosol-generating article 2 accommodated in the accommodation space. Specifically, when the aerosol-generating article 2 is accommodated in the accommodation space of the aerosol-generating device 1 , the heater section 13 can heat the aerosol-generating article 2 with electric power supplied from the battery 11 .

The heater part 13 may be configured in various forms and/or methods.

For example, heater portion 13 can be configured to include an electrically resistive heating element. For example, the heater part 13 includes an electrically insulating substrate (for example, a substrate made of polyimide) and an electrically conductive track, and includes a heating element that generates heat when an electric current flows through the electrically conductive track. be able to. However, the scope of the present invention is not limited to the above examples, and any heating element that can be heated to a desired temperature is applicable without limitation. Here, the desired temperature can be preset in the aerosol generator 1 (eg, when the temperature profile is stored in advance), or can be set at the desired temperature by the user.

As another example, heater portion 13 can be configured to include a heating element that operates in an induction heating manner. Specifically, the heater part 13 may include an inductor (eg, an induction coil) for heating the aerosol-generating article 2 by induction heating and a susceptor that is induction-heated by the inductor. The susceptor can be located inside or outside the aerosol-generating article 2 .

Further, for example, the heater unit 13 includes a heating element for internally heating the aerosol-generating article 2 (hereinafter abbreviated as "internal heating element"), and a heating element for external heating (hereinafter abbreviated as "external heating element"). or can be configured to include a combination thereof. The internal heating element can be, for example, tubular, needle-shaped, or rod-shaped, and can be arranged to penetrate at least a portion of the aerosol-generating article 2, and the external heating element can be plate-shaped, cylindrical, or the like. At least a portion of the aerosol-generating article 2 of the form can be arranged in an enveloping form. However, the scope of the present invention is not limited thereto, and the shape, number, and arrangement of the heating elements may be designed in various ways. A more detailed description of the heating structure of the heater section 13 will be given later with reference to FIGS.

The battery 11 can then supply the power used to operate the aerosol generator 1 . For example, the battery 11 can supply power so that the heater unit 13 can heat the aerosol-generating article 2 and can supply the power necessary for the control unit 12 to operate.

In addition, the battery 11 can supply power necessary for operating electrical components such as a display (not shown), a sensor (not shown), and a motor (not shown) installed in the aerosol generator 1. .

Next, the controller 12 can generally control the operation of the aerosol generator 1 . For example, the control unit 12 can control the operations of the heater unit 13 and the battery 11 and can also control the operations of other components included in the aerosol generator 1 . The control unit 12 can control the power supplied by the battery 11, the heating temperature of the heater unit 13, and the like. The control unit 12 can also check the state of each configuration of the aerosol generator 1 and determine whether the aerosol generator 1 is in an operable state.

The control unit 12 can be implemented by at least one control unit (processor). The controller may be implemented as an array of logic gates, and may be implemented as a combination of a general-purpose microcontroller and a memory storing a program that can be executed by the microcontroller. can also Also, those who have ordinary knowledge in the technical field to which the present disclosure pertains can readily understand that the control unit 12 can be embodied in other forms of hardware.

The aerosol-generating article 2 can have a structure similar to a typical combustible cigarette. For example, the aerosol-generating article 2 can be divided into a first portion (eg tobacco rod) comprising tobacco material (or aerosol-forming substrate) and a second portion (eg filter rod) comprising filters and the like. can. The entire first portion can be inserted inside the aerosol generator 1 and the second portion can be exposed to the outside. Alternatively, only a portion of the first portion may be inserted into the aerosol generator 1, or the entire first portion and a portion of the second portion may be inserted. The user can smoke while holding the second part in his/her mouth.

The aerosol-generating article 2 according to an embodiment of the present invention may be an article filled with tobacco granules, and this embodiment will be described in detail later with reference to FIG. 2 et seq.

Also, the aerosol generator 1 according to the embodiment of the present invention has a smokeless function (that is, a function that does not generate visible smoke or a function that minimizes the generation of visible smoke during use). Also, the aerosol-generating article 2 may be designed to implement a smokeless function. Specifically, the aerosol-generating article 2 is an article filled with tobacco granules, and the aerosol-generating device 1 is operable to heat the aerosol-generating article 2 at a heating temperature of about 270° C. or less. In such cases, no or minimal visible smoke may be generated during smoking, but this is because the tobacco granules are cut tobacco (e.g. leaf tobacco cut tobacco). This is because the amount of moisture and/or aerosol-forming agent is significantly lower than that of tobacco materials such as leaf-cut tobacco, leaf-cut tobacco, and leaf-shaped leaf, and visible smoke generation can be reduced. In addition, tobacco granules can sufficiently develop a smoking taste even at a heating temperature lower than that of tobacco materials such as cut tobacco and plate-shaped leaves (e.g., the heating temperature of cut tobacco is usually 270° C. or higher) ( That is, the nicotine can be sufficiently transferred, the heating temperature of the heater part 13 can be lowered, and the lower heating temperature can further reduce the generation of visible smoke. be. According to this embodiment, since the smokeless function is provided, the user can use the aerosol generator without being restricted by the location or environment, so that the user's convenience can be greatly improved. This embodiment will be described later in more detail together with the structure of the aerosol-generating article 2 with reference to FIG. 6 and subsequent drawings.

FIG. 1 is a drawing for explaining an aerosol generator 1 according to some other embodiments of the present invention.

Aerosol-generating articles 2 according to embodiments of the present invention are smokeless. The smokeless mode means a mode in which aerosol is generated by the aerosol generator 1 but no visible smoke is generated (or a mode in which visible smoke is minimized). The control unit 12 can operate the heater unit 13 to implement the smokeless mode.

So far, an aerosol generator 1 according to several embodiments of the invention has been described with reference to FIG. An aerosol-generating article 2 according to some embodiments of the present invention will now be described with reference to FIG. 2 et seq.

FIG. 2 is an exemplary drawing that schematically illustrates an aerosol-generating article 2 according to some embodiments of the present invention.

As shown in Figure 2, the aerosol-generating article 2 can include a filter rod 22 and a tobacco rod 21 having a cavity formed therein. However, FIG. 2 shows only the components relevant to the embodiment of the present invention. Accordingly, those of ordinary skill in the art to which the present disclosure pertains will appreciate that other general-purpose components can be included in addition to the components shown in FIG. Each component of the aerosol-generating article 2 will be described below.

The filter rod 22 is located downstream of the tobacco rod 21 and can perform a filtering function for aerosols. To this end, the filter rod 22 may contain a filter material such as paper, cellulose acetate fibers, or the like. Filter rod 22 may further include a wrapper wrapping the filter material.

Filter rod 22 can be made in a variety of shapes. For example, the filter rod 22 may be a cylindrical type rod or a tube type rod containing a hollow inside. Alternatively, the filter rod 22 may be a recessed rod. If the filter rod 22 is composed of multiple segments, at least one of the multiple segments may be manufactured with a different shape.

The filter rod 22 can also be made so that flavors are generated. For example, the perfumed liquid may be sprayed onto the filter rod 22 , or a separate fiber coated with the perfumed liquid may be inserted into the filter rod 22 . As another example, filter rod 22 may include at least one capsule (not shown) containing perfume.

Although FIG. 2 illustrates by way of example that the filter rod 22 is constructed from a single segment, the scope of the invention is not so limited and the filter rod 22 may be constructed from multiple segments. can. For example, as shown in FIG. 3, the filter rod 22 may consist of a cooling segment 222 that performs a cooling function for aerosols and a mouthpiece segment 221 that performs a filtering function for aerosols. Or, optionally, filter rod 22 may further include at least one segment that performs other functions.

As a reference, cooling segment 222 can be manufactured in a variety of forms. For example, the cooling segment 222 may be manufactured in the form of a branch pipe, a cellulose acetate filter with hollows, a cellulose acetate filter with a plurality of holes, a filter filled with polymer or biodegradable polymer, or the like. can be done. However, it is not limited to this, and the cooling segment 222 may be manufactured in any form as long as it can perform the function of cooling the aerosol. The polymer or biodegradable polymer may be, but is not limited to, a polylactic acid (PLA) material fabric.

Also, the mouthpiece segment 221 may be, for example, a cellulose acetate filter (that is, a filter made of cellulose acetate fibers), but is not limited to this. The above description for filter rod 22 can also be applied to mouthpiece segment 221 .

Further, description will be made with reference to FIG.

Tobacco rod 21 can be heated as a tobacco rod comprising a cavity or cavity segment 212 to deliver a tobacco component (or smoking component) such as nicotine. As shown, tobacco rod 21 can include first filter segment 211 , second filter segment 213 and cavity segment 212 formed by first filter segment 211 and second filter segment 213 . The cavity segment 212 can then be filled with tobacco granules (214; ie tobacco material in granule form). Tobacco rod 21 may further include a wrapper wrapping the rod.

The first filter segment 211 can be positioned downstream of the cavity segment 212 as a filter segment forming the cavity segment 212 . The first filter segment 211 may further perform aerosol filtering and cooling functions in addition to the cavity forming function.

In some embodiments, first filter segment 211 can include paper material. In other words, the first filter segment 211 can consist of a paper filter. The paper material is preferably arranged longitudinally to ensure a smooth airflow path. However, it is not limited to this. According to this embodiment, a tobacco rod 21 suitable for the heated aerosol generator 1 can be produced. Specifically, the cellulose acetate fiber melts or shrinks when heated above a certain temperature, so it is difficult to apply the cellulose acetate fiber to the tobacco rod portion heated by the heater part 13 . On the other hand, since the paper material is hardly denatured by heat, it can be easily applied to the tobacco rod portion, and through this, the tobacco rod 21 suitable for the heating type aerosol generator 1 can be manufactured. However, in some other embodiments, the first filter segment 211 can also consist of a cellulose acetate filter. In this case, the effect of improving the removal ability of the first filter segment 211 can be achieved.

Also, in some embodiments, the first filter segment 211 can include a water or grease resistant paper material. In this case, the problem that smoke components contained in the aerosol (eg, moisture, aerosol-forming agent components) are absorbed while passing through the first filter segment 211 and the amount of visible smoke is reduced is greatly reduced. be done. For example, if the first filter segment 211 comprises a common paper material, the hygroscopic nature of the paper material may absorb the aforementioned smoke constituents and reduce the amount of visible fumes. However, when a water- or oil-resistant paper material is applied, this fume reduction problem can be solved, since little absorption of the smoke components mentioned above occurs.

Also, in some embodiments, the suction resistance of the first filter segment 211 is about 50 mm _H20 /60 mm to 150 mm _H20 /60 mm, preferably about 50 mm _H20 /60 mm to 130 mm _H20 /60 mm, about 50 mm H20/60 mm. _20/60 mm to 120 mm _H20 /60 mm, about 50 mm _H20 /60 mm to 110 mm _H20 /60 mm or about 50 mm _H20 /60 mm to 100 mm _H20 /60 mm. Appropriate sucking properties can be ensured within such a numerical range. In addition, the appropriate suction property increases the vortex generation probability within the cavity segment 212, thereby achieving the effect of uniformly heating a large number of tobacco granules 214. FIG.

Second filter segment 213 can then be positioned upstream of cavity segment 212 as a filter segment forming cavity segment 212 . The second filter segment 213 may further perform a function of preventing the tobacco granules 214 from falling off. In addition, the second filter segment 213 can ensure that the cavity segment 212 is positioned at the appropriate position within the aerosol generating device 1 when the aerosol generating article 2 is inserted into the aerosol generating device 1 . In addition, the second filter segment 213 can prevent the tobacco rod 21 from detaching to the outside, and can also prevent the aerosol liquefied from the tobacco rod 21 from flowing into the aerosol generator 1 during smoking. can.

In some embodiments, second filter segment 213 can include paper material. In other words, the second filter segment 213 can consist of a paper filter. The paper material is preferably arranged longitudinally to ensure a smooth airflow path. However, it is not limited to this. According to this embodiment, a tobacco rod 21 suitable for the heated aerosol generator 1 can be produced. Specifically, the cellulose acetate fibers are melted or shrunk when they come into contact with the internal heating element, thereby accelerating the dropping of the tobacco granules 214 . However, heat-resistant paper materials can greatly mitigate this phenomenon.

Cavity segment 212 can then be positioned between first filter segment 211 and second filter segment 213 as a segment with a cavity. That is, cavity segment 212 can be formed by filter segment 211 and second filter segment 213 .

Cavity segment 212 can be manufactured in a variety of ways. For example, the cavity segment 212 may be manufactured in a form including a tubular structure such as a branch pipe. Alternatively, the cavity segment 212 can be manufactured by wrapping the cavity formed by the two filter segments 211, 213 with a wrapper of suitable material. However, the scope of the present invention is not limited to this, and the cavity segments 212 may be manufactured in any manner as long as the tobacco granules 214 can be filled.

The length of cavity segment 212 can be freely selected within about 8 mm to 12 mm, although the scope of the invention is not limited to such numerical ranges.

As shown, cavity segment 212 may be filled with tobacco granules 214 . Since the tobacco granules 214 can sufficiently develop a smoking taste even at a lower heating temperature than other types of tobacco materials (eg, leaf tobacco, plate-shaped leaves, etc.), the power consumption of the heater unit 13 can be reduced. can be reduced. In addition, the tobacco granules 214 are easier to reduce the content of moisture and/or aerosol-forming agents than other types of tobacco materials (e.g. leaf tobacco, slabs, etc.) tobacco granules with low content or low aerosol-forming agent content), suitable for implementing the smokeless function of the aerosol generating device 1 .

The tobacco granules 214 may have various diameters, densities, packing ratios, composition ratios of constituent materials, heating temperatures, etc., and may vary depending on the embodiment.

In some embodiments, tobacco granules 214 have a diameter of about 0.3 mm to 1.2 mm. Appropriate hardness and manufacturability of the tobacco granules 214 are ensured within this numerical range, and the probability of eddy current generation within the cavity segment 212 may be increased.

Also, in some embodiments, the density of tobacco granules 214 is between 0.5 g/cm ³ and 1.2 g/cm ³ . Within this numerical range, proper hardness of the tobacco granules 214 can be ensured, and the vortex generation probability within the cavity segment 212 can be increased.

Also, in some embodiments, the fill factor of tobacco granules 214 to cavity segment 212 is less than or equal to about 80% by volume, preferably less than or equal to about 70%, 60%, or 50% by volume. Within this numerical range, the vortex generation probability within the cavity segment 212 can be increased. Also, the filling rate of the tobacco granules 214 is preferably about 20% by volume, 30% by volume, or about 40% by volume or more in order to ensure proper smoking taste.

Also, in some embodiments, the tobacco granules 214 may contain less than about 20% moisture by weight, and preferably less than about 15%, 12%, 10%, 7%, or 5% by weight. of moisture. Within this numerical range, the generation of visible smoke can be greatly reduced, and the smokeless function of the aerosol generator 1 can be easily realized. However, in some other embodiments, tobacco granules 214 may contain more than about 20% water by weight.

Also, in some embodiments, the tobacco granules 214 can contain up to about 10% by weight of the aerosol forming agent, and preferably about 7%, 5%, 3% or 1% by weight of the aerosol forming agent. agent. Alternatively, tobacco granules 214 may not contain an aerosol forming agent. Within this numerical range, the generation of visible smoke may be greatly reduced, and the smokeless function of the aerosol generator 1 can be easily realized. However, in some other embodiments, the tobacco granules 214 may contain about 10% or more by weight of the aerosol forming agent.

Also, in some embodiments, the heating temperature of the tobacco granules 214 is about 270°C, 260°C, 250°C, 240°C, or 230°C or less. In other words, the heater part 13 can heat the tobacco rod 21 at the heating temperature within the illustrated range. Within this numerical range, the problem that the tobacco granules 214 are overheated and develop a burnt taste can be solved. In addition, the smokeless function of the aerosol generator 1 can be easily implemented by minimizing the generation of visible smoke while ensuring proper smoking taste. Supplementally, tobacco substances such as cut tobacco and plate-shaped leaves do not develop a sufficient smoking taste unless they are heated to about 270° C. or higher. As a result, the power consumption of the heater part 13 can be reduced, and the generation of visible smoke can be easily suppressed. In addition, due to these characteristics, the tobacco granules 214 may be more suitable for implementing the smokeless function of the aerosol generator 1 than other types of tobacco materials.

On the other hand, although not explicitly shown, the aerosol-generating article 2 can be wrapped by at least one wrapper. As an example, the aerosol-generating article 2 can be packaged with one wrapper. As another example, the aerosol-generating article 2 can be superimposed by two or more wrappers. For example, a first wrapper may wrap the tobacco rod 21 and a second wrapper may wrap the filter rod 22 . The tobacco rod 21 and filter rod 22 wrapped by separate wrappers are then combined and the entire aerosol-generating article 2 can be rewrapped by a third wrapper. If each of tobacco rod 21 or filter rod 22 is composed of multiple segments, each segment can be wrapped by an individual wrapper. The entire aerosol-generating article 2 combined with segments wrapped by individual wrappers can then be repackaged by another wrapper. The wrapper may have at least one hole through which external air is introduced and internal gas is discharged.

An aerosol-generating article 2 according to some embodiments of the present invention has now been described with reference to FIGS. 2 and 3. FIG. According to the above, an aerosol-generating article 2 loaded with tobacco granules 214 can be provided. Such an aerosol-generating article 2 can give the user a better smoking and friendly feeling than a cartridge-shaped product (i.e., a cartridge product filled with tobacco granules), and can also reduce manufacturing costs.

Moreover, the aerosol-generating article 2 can be provided with an aerosol-generating article 2 suitable for implementing the smokeless function of the aerosol-generating device 1 . Specifically, the aerosol-generating article 2 comprises a tobacco rod 21 filled with tobacco granules 214, which are cut tobacco (e.g. leaf tobacco cut tobacco, flat leaf cut tobacco), flat leaf tobacco, etc. Visible smoke generation can be greatly reduced due to the significantly lower moisture and/or aerosol-forming agent content compared to tobacco materials such as. In addition, since the tobacco granules 214 exhibit sufficient smoking taste even at a relatively low temperature compared to other types of tobacco materials, the heating temperature of the aerosol generator 1 can be set relatively low. , the lower heating temperature may reduce visible smoke generation.

Also, a cavity segment 212 may be formed by filter segments 211 and 213 positioned upstream and downstream of the tobacco rod 21 , and the cavity segment 212 may be filled with tobacco granules 214 . Accordingly, the tobacco rod 21 in which the falling-off phenomenon of the tobacco granules 214 can be minimized can be easily manufactured.

The filter segments 211, 213 can also consist of paper filters. In this case, the problem that the physical properties of the filter segments 211 and 213 are changed due to the heating of the heater part 13 can be prevented.

On the other hand, the inventors of the present invention confirmed that when a tobacco rod is manufactured so as to contain a flavor source, heating the tobacco rod remarkably increases the flavor intensity and flavor persistence, and reduces the offensive odor and taste.

FIG. 2 is an exemplary diagram illustrating how cavity segments and filter segments are formed in an aerosol-generating article 2 according to some embodiments of the present invention. For ease of understanding, the drawings following FIG. 2 show only the tobacco rod 21 without the filter rod 22 .

As shown in FIG. 2, tobacco rod 21 may contain a flavor source. The flavor source, which is not shown separately in the drawing, is at least one selected from the group consisting of flavored sheets, flavored granules, and TJNS filters.

The fragrant sheet according to some embodiments of the present invention can be used after being processed in various forms such as a carved form, a rolling form, or a folding form. When the scented sheet is heated, it gradually releases the perfume fixed inside, thereby greatly improving the persistence of the scent.

Fragrance-containing granules according to some embodiments of the present invention are not particularly limited as long as the granules contain fragrance, and for example, extruded granules containing menthol or the like may be used. can be, but is not limited to.

The TJNS filter according to some embodiments of the present invention is not particularly limited as long as it is a jet type (TJNS) using a nozzle or the like, and for example, a monocellulose filter or a tube filter that jets a flavor component can be used. It can be, but is not limited to.

In the aerosol-generating article 2 according to some embodiments of the present invention, the tobacco rod includes filter segments 211, 213 and cavity segments 212, wherein any one or more of said filter segments and cavity segments includes a flavoring agent. be able to. In the aerosol-generating article 2 according to some embodiments of the present invention, one or more of the filter segment and the cavity segment includes a flavoring source that is heated from the outside of the tobacco rod by a heater section described below. Thereby, the migration of the aroma contained in the flavor source can be increased.

Specifically, the filter segment includes a first filter segment 213 and a second filter segment 211, the first filter segment 213 located downstream of the cavity segment 212, and the second filter segment 211 located downstream of the cavity. Located upstream of the segment 212 , the cavity segment 212 can be formed by the first filter segment 213 and the second filter segment 211 . Also at this time, any one or more flavor source selected from the group consisting of a scented sheet, granules containing scent, and TJNS filter consists of the first filter segment 213, the second filter segment 211, and the cavity segment 212. Any one or more selected from the group can be included.

In the aerosol-generating article 2 according to some embodiments of the present invention, the cavity segment 212 may include any one or more of scented granules and scented sheets.

In the aerosol-generating article 2 according to some embodiments of the present invention, the first filter segment 213 or the second filter segment 211 may include any one or more of TJNS filter and scented sheet.

It has been described above with reference to FIG. 2 how the flavorants contained in the aerosol-generating article are contained in the aerosol-generating article. Hereinafter, the heating structure of the heater part 13 according to some embodiments of the present invention will be described with reference to FIGS. 4 and 5. FIG.

First, the heating structure of the heater part 13 according to the embodiment of the present invention will be described with reference to FIG.

As shown in FIG. 4, the heater section 13 according to this embodiment can be configured to include an external heating element 131, and the external heating element 131 can be arranged to heat only the cavity segment 212. can. For example, the external heating element 131 can be arranged to wrap at least a portion of the cavity segment 212 . In this case, only the flavor source contained in the cavity segment 212 is heated by the heat of the heater part 13 to provide a special flavor.

Also, as shown in FIG. 5, the heater section 13 according to this embodiment can be configured to include an external heating element 131, and the external heating element 131 is in contact with the cavity segment 212; a portion of any one of the first filter segment 213 and the second filter segment 211; For example, the external heating element 131 can be arranged to enclose at least a portion of the cavity segment 212 and the filter segment. In this case, the first filter segment 213 and the second filter segment 211 in contact with the cavity segment 212 can be heated outside the cavity segment 212 , so that the heat of the heater section 13 can be used to extract the flavor contained in the filter segments 211 and 213 . Raw materials can be heated to provide flavor.

In addition, in the heating structure of the heater part 13 according to another embodiment of the present invention, the heater part 13 can heat the cavity segment 212 by induction heating through a particle-shaped susceptor material (hereinafter referred to as "susceptor particles"). can. Specifically, the heater part 13 can be configured to include an inductor (eg, an induction coil) for induction heating the susceptor material, and a large number of susceptor particles are arranged inside the cavity segment 212 . can In this case, a plurality of susceptor particles are mixed with the tobacco granules 214 inside the cavity segment 212 to heat the tobacco granules 214, so that the tobacco granules 214 can be uniformly heated.

There are various ways to arrange the susceptor particles. For example, susceptor particles can be packed inside cavity segment 212 with tobacco granules 214 . Alternatively, the susceptor particles may form part of the tobacco granules 214 . In other words, the tobacco granules 214 containing susceptor particles can be produced by adding susceptor particles during production of the tobacco granules 214 .

In some embodiments, the flavored sheet can be introduced in chopped form.

In some other embodiments, as shown in FIG. 6, the scented sheet 10 can be introduced in a rolled or folded form. For example, the scented sheet 10 may be rolled or folded in an irregular pattern (see 10-1), spirally (see 10-2), concentrically (see 10-3), or folded many times. It can be put into the filter segments 211 and 213 and the cavity segment 212 in a folded form (see 10-4; e.g. a folded form to secure an airflow path in the longitudinal direction). When the scented sheet 10 is put in the illustrated form, an airflow path is secured in the longitudinal direction, thereby ensuring smooth airflow and appropriate suction resistance. In addition, the contact area between the fragrant sheet 10 and the high-temperature airflow is increased, and the migration amount of the fragrant can be increased.

Also, in some other embodiments, the scented sheet 10 can be applied (e.g. adhered) to the wrapper of the aerosol-generating article. For example, the scented sheet 10 can be placed inside the wrapper of the filter segments 211 , 213 and the cavity segment 212 . If the wrapper includes metal foil, the flavored sheet 10 can be placed inside the metal foil. Alternatively, the scented sheet 10 can constitute at least part of the wrapper. For example, the fragrant sheet 10 itself functions (is used) as a wrapper, or a wrapping material produced by integrating the fragrant sheet 10 and wrapping paper can be used as the wrapper.

In the embodiments described above, the scented sheet 10 may be processed through a predetermined process. However, the specific processing forms are various.

For example, as shown in FIG. 7, the scented sheet 10 is processed so that it can be wrinkled or folded in the longitudinal direction (ie, MD direction) of the aerosol-generating article. For example, the fragrant sheet 10 may be wrinkled or folded by at least one of a crimping process, a pleating process, a folding process, and a gathering process. may be Specifically, the crimping process is a process in which creases are given to the sheet surface through roller pressure and speed difference of a crimping machine, and is divided into a wet process and a dry process. The wet process means a process in which the base paper is wetted with water, softened, crimped, and dried again. A dry process means a drying process with two dryers with different mutual temperatures. Those skilled in the art are already familiar with the pleating process, the folding process, and the gathering process, and thus the description thereof will be omitted. According to this example, a number of channels can be formed in the longitudinal direction of the scented sheet 10 through at least one of the illustrated processes, and smooth air flow and proper suction can be achieved through the formed channels. Resistance can be guaranteed. In addition, the contact area between the fragrant sheet 10 and the high-temperature airflow is increased, and the migration amount of the fragrant material can also be increased.

The scented sheet 10 described above can be manufactured through steps of preparing a liquid (eg slurry) sheet composition and drying the prepared sheet composition. Here, the liquid state includes not only a liquid state but also a state in which a liquid and a solid are mixed (eg slurry state). For example, the scented sheet 10 can be produced by stretching (casting) a sheet composition on a predetermined base material and drying it. However, it is not limited to this, and the specific manufacturing method may change.

Although the detailed composition of the sheet composition can be designed in various ways, in some embodiments, distilled water, a solvent such as ethanol, a polysaccharide substance (or hydrocolloid substance), and a fragrance are blended. A sheet composition can be formed. The scented sheet 10 produced from such a sheet composition is excellent in scent retention and scent retention, and can greatly improve the scent expression and scent persistence of the aerosol-generating article. Each component of the sheet composition will be described below.

Solvents such as distilled water and ethanol are factors for adjusting the viscosity of the slurry type sheet composition.

Next, the polysaccharide substance is a substance that coats and fixes the perfume, and at the same time, it is a sheet-forming agent that forms a sheet. Examples of polysaccharide materials include cellulosic materials such as hydroxypropylmethylcellulose (HPMC), methylcellulose (MC), carboxymethylcellulose (CMC), agar, and the like. Since the cellulosic material has a property of absorbing hot air well through a phase change when it comes into contact with a high-temperature air stream, the fragrant sheet 10 can be utilized not only as a fragrant material but also as a cooling material. can be done.

In some embodiments, the sheet composition can include cellulose modified among various polysaccharide materials. Here, "modified cellulose" may mean cellulose in which specific functional groups are substituted in the molecular structure. Examples of modified celluloses include, but are not limited to, HPMC, MC, CMC, EC. For example, HPMC can have a grade within the range of about 4 to 40,000 depending on the degree of hydroxypropyl and methyl (or methoxy) substitution and molecular weight. The grade can determine the viscosity of the modified cellulose. More specifically, the physicochemical properties of HPMC are related to the proportion of methoxy groups, the proportion of hydroxypropyl groups, and the molecular weight. It can be classified into HPMC1828, HPMC2208, HPMC2906, and HPMC2910 according to the ratio. Here, the first two numbers can mean the proportion of methoxy groups, and the last two numbers can mean the proportion of hydroxypropyl groups. As a result of continuous experiments by the present inventors, it was confirmed that the fragrant sheet 10 produced from the sheet composition containing the modified cellulose is excellent in the physical properties of the sheet and in the amount of fragrance retained.

Next, examples of fragrances include menthol, nicotine, nicotine salts, leaf tobacco extracts, leaf tobacco extracts containing nicotine, natural plant flavors (eg cinnamon, sage, herbs, chamomile, hay, Sweet Tea, Clove, Lavender, Cadmom, Clove, Nutmeg, Bell Mot, Geranium, Honey Essence, Rose Oil, Lemon, Orange, Cinnamon, Celery, Jasmine, Ginger, Coriander, Vanilla Extract, Spearmint, Peppermint, Cassia, Coffee, Celery , Cascarilla, sandalwood, cocoa, ylang ylang, fennel, anise, licorice, saint zons bread, plum extract, peach extract, etc.), sugars (eg. glucose, fructose, isomerized sugar, caramel, etc.), cocoa Liquids (powder, extract, etc.), esters (eg, isoamyl acetate, linalyl acetate, isoamyl propionate, linalyl butyrate, etc.), ketones (eg, menthone, oinone, damascenone, ethyl maltol, etc.), alcohols (eg, geraniol, linalool, anethole, eugenol, etc.), aldehydes (eg, vanillin, benzaldehyde, anisaldehyde, etc.), lactones (eg, γ-undecalactone, γ-nonalactone, etc.), animal fragrances (eg mask, ambagrease, civet, castoreum, etc.), and hydrocarbons (eg limonene, pinene, etc.). The perfume may be used as a solid, or dissolved or dispersed in an appropriate solvent such as propylene glycol, ethanol, benzyl alcohol, or triethyl sheetate. In addition, fragrances that are easily dispersed in a solvent by addition of an emulsifier, such as hydrophobic fragrances and oil-soluble fragrances, can be used. These perfumes can be used alone or in mixtures. However, the scope of the present invention is not limited by the examples described above.

In some embodiments, perfumes with a melting point of about 80° C. or less can be utilized. In this case, when the fragrant sheet 10 comes into contact with an air current of 80° C. or higher, the perfume undergoes a phase change and further absorbs hot air, so that the cooling performance of the fragrant sheet 10 can be further improved. Considering that the temperature of heated aerosols is generally 80° C. or higher, the use of such fragrances can effectively enhance the cooling performance of most aerosol-generating articles. Not only that, the ease of volatilization of the phase-changed perfume can also enhance the scent development of the aerosol-generating article. Examples of perfumes having a melting point of about 80° C. or less include, but are not limited to, menthol.

Meanwhile, in some embodiments, the sheet composition may further include LM-pectin (low methoxyl pectin). LM-pectin is a low ester pectin or a low methoxyl pectin with relatively little esterification, specifically pectin containing less than about 50% of carboxyl groups in the molecular structure. can do. Unlike carrageenan, LM-pectin does not gel when left to cool, so it can reduce the viscosity of the slurry-type sheet composition (eg, about 600 cp to 800 cp). At the same time, the slurry-type sheet composition can be produced without emulsifiers, freeing from safety problems caused by emulsifiers.

LM-pectin can contain less than about 50%, less than about 40%, less than about 30%, less than about 20%, or less than about 10% carboxy groups within the molecular structure. The lower the content of carboxy groups within the molecular structure of LM-pectin, the lower the viscosity of the slurry containing LM-pectin.

Also, in some embodiments, the sheet composition can further include a bulking agent. A bulking agent is a substance that increases the total mass of components other than distilled water (that is, the mass of the building), increases the volume of the fragrant sheet 10 to be manufactured, and does not affect the original function of the fragrant sheet 10. is. Specifically, the bulking agent increases the volume of the scented sheet 10, does not substantially increase the viscosity of the slurry, and does not adversely affect the perfume retaining function of the scented sheet 10. - 特許庁Preferably, the bulking agents are starches, modified starches, or starch hydrolysates. However, it is not limited to this.

Modified starch includes acetic acid starch, oxidized starch, hydroxypropyl distarch phosphate, hydroxypropyl starch, distarch phosphate, monostarch phosphate, distarch phosphate, and the like.

A starch hydrolyzate refers to a material obtained by a process that includes the step of hydrolyzing starch. The starch hydrolyzate includes, for example, a substance obtained by directly hydrolyzing starch (i.e., dextrin), or a substance obtained by hydrolyzing starch after heat treatment (i.e., indigestible dextrin). can be done. The bulking agent may be, for example, a dextrin, more specifically a cyclodextrin.

The starch hydrolyzate is generally a starch hydrolyzate with a DE value in the range of about 2 to about 40, preferably a starch hydrolyzate with a DE value in the range of about 2 to about 20. Examples of starch hydrolysates having a DE value in the range of about 2 to about 20 include Pine Index #100 (Matsutani Chemical Industry Co., Ltd.), Pine Fiber (Matsutani Chemical Industry Co., Ltd.), TK-16 ( Matsutani Chemical Industry Co., Ltd.) can be utilized.

Here, "DE" is an abbreviation for dextrose equivalent, and the DE value indicates the degree of hydrolysis of starch, that is, the dextrose equivalent of starch. The DE value in the present disclosure is a value measured by the Willstatter-Schudel method. The properties of hydrolyzed starch (starch hydrolysate), such as the molecular weight of the starch hydrolyzate and the arrangement of sugar molecules that make up the starch hydrolyzate, are not constant for each starch hydrolyzate molecule. , exist with some distribution or variation. The starch hydrolyzate may exhibit different physical properties (eg, DE value) for each molecule depending on the distribution or variation of the properties of the starch hydrolyzate, or the difference in cut sections. Thus, a starch hydrolyzate is a collection of molecules exhibiting different physical properties. It is treated as a representative value that indicates the degree.

Preferably, the starch hydrolyzate can be selected from the group consisting of dextrins having a DE value of about 2 to about 5, resistant dextrins having a DE value of about 10 to about 15, and mixtures thereof. As a dextrin having a DE value of about 2 to about 5, Paindex #100 (Matsutani Chemical Industry Co., Ltd.), for example, can be utilized. As an indigestible dextrin having a DE value of about 10 to about 15, for example, pine fiber (Matsutani Chemical Industry Co., Ltd.) can be used.

Also, in some embodiments, the sheet composition can further include a plasticizer. The plasticizer can improve the physical properties of the fragrant sheet 10 by imparting appropriate flexibility to the fragrant sheet 10 . Plasticizers can include, for example, but are not limited to, at least one of glycerin and propylene glycol.

Also, in some embodiments, the sheet composition can further include an emulsifier. The emulsifier can increase the amount of scent retained in the scented sheet 10 by allowing the strong fat-soluble flavor and the water-soluble polysaccharide substance to be well mixed. Examples of emulsifiers include, but are not limited to, lecithin.

Meanwhile, the scented sheet 10 manufactured from the above sheet composition may have various content ratios (composition ratios).

In some embodiments, the scented sheet 10 may include about 20 to 60 parts by weight of polysaccharide material and about 10 to 50 parts by weight of perfume based on 100 parts by weight of the total. Of course, the scented sheet 10 can also contain an appropriate amount of water. It has been confirmed that the scented sheet 10 constructed in this manner greatly enhances the scent expression, scent retention and cooling performance of the aerosol-generating article.

In some embodiments, the flavored sheet 10 contains from about 2 to about 15 parts by weight moisture, from about 25 to about 90 parts by weight modified cellulose, and from about 0.1 to about 60 parts by weight of perfume may be included.

Also, in some embodiments, the flavored sheet 10 comprises, based on 100 parts by weight of the total, about 2 to about 15 parts by weight moisture, about 1 to about 60 parts by weight polysaccharide material, and about 1 to about 60 parts by weight. of LM-pectin and from about 0.1 to about 60 parts by weight of perfume.

In some embodiments, the plasticizer may be included in an amount of about 0.1 to about 15 parts by weight, preferably about 1 to 10 parts by weight, based on 100 parts by weight of the entire scented sheet 10. can be included. For example, the scented sheet 10 may contain about 20 to 60 parts by weight of polysaccharide material, about 10 to 50 parts by weight of flavor, and about 1 to 10 parts by weight of plasticizer based on 100 parts by weight of the total. A sheet having appropriate flexibility (physical properties) can be formed within such a numerical range, and the fragrant sheet 10 can be easily processed (eg crimping, rolling, folding, etc.). Workability can be improved. For example, if too little plasticizer is added, the flexibility of the sheet will be reduced and it will be easily damaged during the process, and if too much plasticizer is added, the sheet will not form well. There is also
