Description

Aerosol-generating device providing a customised smoking experience and aerosol-generating article suitable for use with such a device

Technical Field

The present disclosure relates to an aerosol-generating device providing a customised smoking experience and an aerosol-generating article suitable for use with the device. More particularly, the present disclosure relates to an aerosol-generating device capable of providing a customized smoking experience based on user preferences through various adjustment functions of flavour adjustment, aerosol amount adjustment, etc., and aerosol-generating articles designed to be suitable for use with the device.

Background

In recent years, there has been an increasing demand for alternative products that overcome the disadvantages of existing cigarettes. For example, there is an increasing demand for a device for generating aerosol by electrically heating a cigarette and a heated cigarette applied to the device, and thus, research into a heated aerosol-generating device and a heated cigarette is being actively conducted.

In recent years, with diversification of user preferences, research for providing a customized smoking experience is also actively underway.

Hereinafter, various embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

First, aerosol-generating devices 100-1 to 100-3 according to various embodiments of the present disclosure will be explained with reference to fig. 1 to 3.

Figure 1 is a schematic diagram schematically illustrating an aerosol-generating device 100-1 according to some embodiments of the present disclosure. In particular, the aerosol-generating article 150 is illustrated in fig. 1 as being housed in the aerosol-generating device 100-1.

As shown in fig. 1, the aerosol-generating device 100-1 may include a housing, a heater section 140, a battery 130, and a control section 120. However, this is only a preferred embodiment for achieving the object of the present disclosure, and some components may of course be added or deleted as needed. Furthermore, each component of the aerosol-generating device 100-1 as shown in fig. 1 represents a functionally divided functional element, and is implemented in a form in which a plurality of components are integrated with each other in an actual physical environment, or may be implemented in a form in which a single component is divided into a plurality of detailed functional elements. Next, each component of the aerosol-generating device 100-1 will be explained.

The housing may form the appearance of the aerosol-generating device 100-1. Also, the housing may form a receiving space for receiving the aerosol-generating article 150. Preferably, the outer shell is formed of a strong material capable of protecting the internal components.

In some embodiments, a user interface module may be formed on an outer surface of the housing. Further, the aerosol-generating device 100-1 may adjust the heater section 140 based on user input received through the user interface module to provide a customized smoking experience. The user interface module may be implemented in various forms, such as buttons, a touchable display, and the like. The present embodiment will be described in detail later with reference to fig. 4 and the like.

In addition, the heater section 140 may be arranged to heat the aerosol-generating article 150 received in the receiving space. The aerosol-generating article 150 comprises a solid aerosol-forming substrate and may generate an aerosol by heating. The generated aerosol may be inhaled through the mouth of the user. The operation, heating temperature, and the like of the heater section 140 can be controlled by the control section 120.

In some embodiments, the heater part 140 may include a user-controlled heater (hereinafter, simply referred to as a "controlled heater") that can be adjusted based on a user input. For example, the heater section 140 may comprise a basic heater and a control type heater that heat the aerosol-generating article 150 according to a pre-stored temperature profile. The user may enjoy a customized smoking experience by directly controlling the control-type heater. The present embodiment will be described in detail later with reference to fig. 4 and the like.

In addition, the battery 130 may supply power for operating the aerosol-generating device 100-1. For example, the battery 130 may supply power to enable the heater section 140 to heat the aerosol-forming substrate contained in the aerosol-generating article 150, or may supply power required for the operation of the control section 120.

Furthermore, the battery 130 may supply power necessary for the operation of electrical components such as a display (not shown), a sensor (not shown), and a motor (not shown) provided in the aerosol-generating device 100-1.

The control unit 120 may control the operation of the aerosol-generating device 100-1 as a whole. For example, the control unit 120 may control the operation of the heater unit 140 and the battery 130, or may control the operation of other components included in the aerosol-generating device 100-1. The control part 120 may control power supplied from the battery 130, a heating temperature of the heater part 140, and the like. Further, the control portion 120 may determine whether the aerosol-generating device 100-1 is in an operable state by confirming the state of each component of the aerosol-generating device 100-1.

The control part 120 may be implemented by at least one processor (processor). The processor may be implemented by a plurality of logic gate arrays, or may be implemented by a combination of a general-purpose microprocessor and a memory in which a program executable by the microprocessor is stored. It should be noted that the control unit 120 may be implemented by other hardware as long as it is understood by a person of ordinary skill in the art to which the present disclosure pertains.

On the other hand, in various embodiments of the present disclosure, a customized smoking experience may be provided by an additive holder of the aerosol-generating article 150 and a controlled heater for heating the additive holder. In this case, the additive contained in the additive containing portion is a substance that can change the smoking experience, and is also a substance that can change the expression level by heating, and examples thereof include, but are not limited to, a flavoring agent, a moisturizing agent, and a sounding agent. The present embodiment will be described in detail later with reference to fig. 4 and the like.

In the following, other types of aerosol-generating devices 100-2, 100-3 will be explained with reference to fig. 2 and 3.

Figure 2 illustrates an aerosol-generating device 100-2 with a vaporizer 1 and an aerosol-generating article 150 arranged side by side, and figure 3 illustrates an aerosol-generating device 100-3 with a vaporizer 1 and an aerosol-generating article 150 arranged in line. However, the internal structure of the aerosol-generating device is not limited to the structure illustrated in fig. 2 and 3, and the arrangement of the components may be changed according to the design method.

In fig. 2 and 3, the vaporizer 1 may comprise a reservoir for storing a liquid aerosol-forming substrate, a wick (wick) for absorbing the aerosol-forming substrate, and a vaporization member for vaporizing the absorbed aerosol-forming substrate to generate an aerosol. The vaporization element may be implemented in various forms, for example, a heating element, a vibration element, and the like. Furthermore, in some embodiments, the vaporizer 1 may be designed as a structure that does not include a wick.

The aerosol generated by the vaporizer 1 may pass through the aerosol-generating article 150 and be inhaled through the mouth of a user. The vaporizing element of the vaporizer 1 may also be controlled by the control portion 120.

Thus far, aerosol-generating devices 100-1 to 100-3 according to various embodiments of the present disclosure have been described with reference to fig. 1 to 3. In the following, the principles of operation of the aerosol-generating article 150 and the heater section 140, which are capable of providing a customised smoking experience, will be described in detail with reference to the drawings such as figure 4.

First, an aerosol-generating article 150-1 and a heater section 140 according to a first embodiment of the present disclosure will be described with reference to fig. 4 to 5.

Fig. 4 and 5 are schematic diagrams for explaining the detailed structure of the aerosol-generating article 150-1 and the principle of operation of the heater section 140 according to the first embodiment of the present disclosure.

As shown in fig. 4 and 5, an aerosol-generating article 150-1 according to the present embodiment may comprise an aerosol-forming substrate portion 151, a filter portion 152 and an additive-containing portion 153. However, fig. 4 and 5 only show components related to the embodiments of the present disclosure. Accordingly, one of ordinary skill in the art to which this disclosure pertains will appreciate that other general components besides those illustrated may also be included. Furthermore, fig. 4 and 5 illustrate only some examples of aerosol-generating articles according to various embodiments of the present disclosure, and the detailed structure of the aerosol-generating articles may differ from that illustrated. In the following, the components of the aerosol-generating article 150-1 will be described.

The aerosol-forming substrate portion 151 may be located upstream of the filter mouth 152 to perform the function of forming aerosol a. In particular, the aerosol-forming substrate portion 151 may comprise an aerosol-forming substrate, and an aerosol may be formed by the aerosol-forming substrate. The aerosol-forming substrate portion 151 is heated by the heater portion 140 to form an aerosol. The formed aerosol can be delivered to the mouth of the user by suction through the filter mouthpiece 152. The aerosol-forming substrate portion 151 may also comprise a wrapper (wrapper) around the aerosol-forming substrate.

Since the aerosol-forming substrate portion 151 is formed in a rod (rod) shape, it may be referred to as an "aerosol-forming rod 151" or a "cigarette rod 151" as the case may be. Or, it may be referred to as "media part 151" according to circumstances.

In some embodiments, the aerosol-forming substrate portion 151 may also comprise a flavour sheet. For example, cut pieces of flavor chips and cut filler (e.g., cut tobacco leaves, reconstituted cut tobacco leaves) may be mixed and contained in the aerosol-forming substrate portion 151. In this case, as it is heated, the fragrance immobilized within the fragrance sheet is slowly released, and thus the fragrance longevity of the aerosol-generating article 150-1 can be greatly improved. The fragrance sheet will be described in detail later.

In addition, the filter mouth 152 may be located downstream of the aerosol-forming substrate portion 151 to perform a filtering function for the aerosol. To this end, the filter mouthpiece 152 may include a filter material. Examples of the filtering substance may include cellulose acetate fiber, paper, and the like, but are not limited thereto. Further, the filter mouth 152 may be located at a downstream end portion of the aerosol-generating article 150-1 to serve as a mouthpiece for contact with the mouth of a user. The filter plug 152 may also include a wrapper that surrounds the filter material (filter plug).

Since the filter portion 152 is also formed in a rod shape, it may be referred to as a "filter rod 152" according to circumstances, and may be formed in various shapes including a cylindrical shape, a tubular shape including a hollow inside (for example, a tubular cellulose acetate filter), an insertion shape, and the like. Alternatively, the filter portion 152 serves as a mouthpiece, and thus may be referred to as a "mouthpiece portion 152".

The additive container 153 may contain a predetermined additive. The additive can be a substance which can change the smoking experience of a user in any form, and can also be a substance which can adjust the expression degree through heating. For example, the additives may include, but are not limited to, a fragrance capable of changing taste or smell experience elements, a moisturizer (humectant) capable of changing visual experience elements, and a sound emitting agent capable of changing auditory experience elements. The additive containing part 153 may further include a packing paper.

For example, the humectant may include at least one of glycerin, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. However, the present disclosure is not limited thereto. The humectant maintains moisture at a suitable level, softens the inherent taste, and enriches the amount of aerosol.

For example, flavorants may include licorice, sucrose, fructose syrup, iso-sugar (isosweet), cocoa, lavender, cinnamon, cardamom, celery, fenugreek, casaria, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon oil, orange oil, peppermint oil, cinnamon, caraway, cognac, jasmine, chamomile, cinnamon, iland ylang, salvia, spearmint, ginger, coriander, clove extract (or clove material), coffee, or the like. However, the present disclosure is not limited thereto.

In some embodiments, a scented sheet may be used as a scent agent. The fragrance sheet may be processed into various forms such as a cut sheet form, a rolled (rolling) form, or a folded (folding) form, to be added to the additive holder 153. With being heated, the fragrance sheet gradually releases the fragrance fixed inside, and the fragrance durability can be greatly improved. The fragrance sheet will be described in detail later.

The sound generator may be a substance that is capable of generating sound when heated. For example, the sound generator may include a scented sheet that is made porous. When the above fragrance sheet is heated, the internal pores (or the film forming the pores) may burst and generate sound. For example, porous fragrance sheets can be made from a sheet composition containing a solvent such as distilled water (water) and/or ethanol, a hydrocolloid material, and an oily fragrance. The fragrance sheet made from the sheet composition described above is porous and therefore can function as a sound generating element in the aerosol-generating article 150-1. For example, porous fragrance tablets can be prepared by forming a plurality of pores in the composition while mixing the hydrocolloid substance and lipophilic fragrance with the solvent, and as the above-described sheet composition is dried. Additional description of the fragrance sheet will be described later.

As shown, the additive containing portion 153 may be located downstream of the aerosol-forming substrate portion 151. In this case, since the high-temperature aerosol formed in the aerosol-forming substrate portion 151 passes through the additive containing portion 153, the contained additive can be smoothly expressed (transferred). However, the scope of the disclosure is not limited in this regard and the additive containing portion 153 may also be located upstream of the aerosol-forming substrate portion 151. For example, when the additive containment 153 comprises a humectant, the additive containment 153 may be located upstream of the aerosol-forming substrate portion 151.

In addition, the heater section 140 may comprise a primary heater 141 for heating the aerosol-forming substrate section 151 and a control type heater 142 for heating the additive containing section 153. The primary heater 141 may be used to heat the aerosol-forming substrate portion 151 to provide a primary (general) smoking experience, and the controlled heater 142 may be controlled based on user input to provide a tailored smoking experience.

As described above, the primary heater 141 may heat the aerosol-forming substrate portion 151 based on a pre-stored temperature profile. In other words, the basic heater 141 may be a heater controlled by the control part 120 based on a temperature profile stored in advance.

The basic heater 141 may be implemented in various forms. For example, the basic heater 141 may be implemented as an internal heating type heater as shown in fig. 4, or may be implemented as an external heating type heater as shown in fig. 5. Further, the basic heater 141 may be implemented as a resistance heater, or may be implemented in an induction heating manner.

In addition, the control-type heater 142 may provide a customized smoking experience by heating the additive holder 153. For example, as shown, the control type heater 142 may be implemented as an external heating type heater to externally heat at least a portion of the additive containing part 153. Further, the control type heater 142 may provide a customized smoking experience by controlling (adjusting) the degree of heating of the additive containing part 153 based on user input (i.e., by adjusting the degree of expression of the contained additive). However, the specific control manner thereof may be different according to the embodiment.

In some embodiments, whether the control type heater 142 is operated or not may be controlled based on user input. For example, the control type heater 142 may be turned on (on) or off (off) according to a user input. In this case, the user can enjoy a customized smoking experience by controlling on/off of the control type heater 142.

Also, in some embodiments, the degree of heating of the control-type heater 142 may be controlled based on user input. For example, the control-type heater 142 may operate at a first heating intensity in response to a first user input, and may operate at a second heating intensity in response to a second user input. In this case, the first user input and the second user input may be the same user input (e.g., a push button). According to this embodiment, the degree of performance (e.g., flavor intensity, level of amount aerosolized) of the additive can be more precisely adjusted to provide a more appropriate customized smoking experience.

Also, in some embodiments, the heating mode of the control type heater 142 may be controlled based on user input. For example, the control-type heater 142 may be operated in a manual mode in response to a first user input and may be operated in an automatic mode in response to a second user input. In this case, the first user input and the second user input may be the same user input (e.g., a push button). In the manual mode, whether the control type heater 142 is operated, the heating intensity, may be controlled based on a user input. In the automatic mode, the control type heater 142 can be operated regardless of the user input. For example, the control part 120 may automatically control the control type heater 142 based on the pumping mode of the user. As a more specific example, when the pumping intensity is increased, the pumping interval is shortened, or the pumping length is increased, the control part 120 may turn on the control type heater 142 or increase the heating intensity. In the opposite case, the control part 120 may turn off the control type heater 142 or reduce the heating intensity. In the automatic mode, the control unit 120 may operate the control type heater 142 according to a temperature profile stored in advance.

On the other hand, the control type heater 142 may be controlled based on user input received through the user interface module. For example, the control part 120 may control the control type heater 142 based on a user input received through the user interface module, but is not limited thereto.

The user interface module may be implemented in various forms, such as buttons, a touchable display, a voice recognition module, and so forth. For example, the user interface module may be implemented as a button formed on an outer surface of a housing of an aerosol-generating device (e.g., aerosol-generating device 150-1). In this case, the user can control the control type heater 142 by a simple input of pressing a button, so that the user's convenience can be improved.

On the other hand, in some embodiments, the control type heater 142 may be implemented as an external heating type heater, and the fragrance may be added to the additive containing portion 153. Also, flavourants (e.g. flavourant tablets) may be added to the wrapper of the additive containing portion 153 or an adjacent segment (e.g. aerosol-forming substrate portion 151, filter portion 152, filter portions 154, filter portions 155, filter portions 158 of fig. 7 or 8, etc.). In this case, as the control type heater 142 is operated, the fragrance of the portion of the wrapper located near the control type heater 142 is rapidly transferred, so that the delay of fragrance transfer can be minimized. In other words, even if the control type heater 142 is operated (turned on) by the user, it may take a certain time to effect the transfer of the fragrance. This is because it takes a while to sufficiently heat the additive containing part 153. In other words, the transfer of the fragrance may be delayed until the control type heater 142 sufficiently heats the additive containing part 153, but according to the present embodiment, the problem can be easily solved.

Thus far, the detailed structure of the aerosol-generating article 150-1 and the principle of operation of the heater section 140 according to the first embodiment of the present disclosure have been explained with reference to fig. 4 and 5. As described above, it is possible to provide the heater 142 as a dedicated heater for the additive containing portion 153 while being controllable by the user. The control type heater 142 heats the additive holder 153 based on user input, so that a customized smoking experience based on user preferences may be provided.

Hereinafter, the detailed structure of the aerosol-generating article 150-2 and the principle of action of the heater section 140 according to the second embodiment of the present disclosure will be described. However, for the sake of clarity of the present disclosure, the description of the contents overlapping with the foregoing embodiments will be omitted.

Fig. 6 is a schematic diagram for explaining the detailed structure of the aerosol-generating article 150-2 and the operating principle of the heater section 140 according to the second embodiment of the present disclosure. For reference, in the drawings such as fig. 6, the basic heater 141 is not illustrated for the sake of easy understanding.

As shown in fig. 6, the aerosol-generating article 150-2 according to the present embodiment may include a plurality of additive containing parts (a first additive containing part 153-1, a second additive containing part 153-2), and the heater part 140 may also include a plurality of control type heaters (a first control type heater 142-1, a second control type heater 142-2). At this time, the first control type heater 142-1 may heat the first additive containing part 153-1, and the second control type heater 142-2 may heat the second additive containing part 153-2.

Fig. 6 illustrates a case where the aerosol-generating article 150-2 has two additive containers (first additive container 153-1 and second additive container 153-2), but the number of additive containers may be three or more. Further, although fig. 6 illustrates a case where a plurality of additive containing parts (first additive containing part 153-1, second additive containing part 153-2) are positioned adjacent to each other, a plurality of additive containing parts (first additive containing part 153-1, second additive containing part 153-2) may not be adjacent. For example, a first additive containing portion 153-1 may be located upstream of the aerosol-forming substrate portion 151 and a second additive containing portion 153-2 may be located downstream of the aerosol-forming substrate portion 151.

The additives added to the respective additive containing parts (the first additive containing part 153-1, the second additive containing part 153-2) may be the same or may be different.

When the same additive is added, the degree of transfer of the additive can be controlled more precisely. For example, when the same fragrance is added to two additive containing parts (first additive containing part 153-1, second additive containing part 153-2), the flavor intensity can be controlled more precisely by two control type heaters (first control type heater 142-1, second control type heater 142-2). For example, a user may feel a very strong fragrance by simultaneously operating (turning on) two control type heaters (the first control type heater 142-1 and the second control type heater 142-2), and a user may feel an intermediate level of fragrance by operating (turning on) only one control type heater (the first control type heater 142-1 or the second control type heater 142-2).

When different additives are added, a colorful smoking experience can be provided for the user. For example, when different scents are added to the two additive containing parts (the first additive containing part 153-1 and the second additive containing part 153-2) and the two control type heaters (the first control type heater 142-1 and the second control type heater 142-2) are simultaneously operated, the two scents may be combined and transferred to the user. Alternatively, when only one control type heater (the first control type heater 142-1 or the second control type heater 142-2) is operated, only the fragrance added to the corresponding additive containing portion (the first additive containing portion 153-1 or the second additive containing portion 153-2) may be strongly transferred. As another example, when a fragrance and a humectant are added to two additive containing parts (first additive containing part 153-1, second additive containing part 153-2) respectively and two control type heaters (first control type heater 142-1, second control type heater 142-2) are simultaneously operated, the fragrance transfer and the atomization amount can be simultaneously enhanced.

Thus far, the detailed structure of the aerosol-generating article 150-2 and the principle of operation of the heater section 140 according to the second embodiment of the present disclosure have been explained with reference to fig. 6. As described above, it is possible to improve the control accuracy by the plurality of additive containing parts (first additive containing part 153-1, second additive containing part 153-2) and the plurality of control type heaters (first control type heater 142-1, second control type heater 142-2) and provide a user with various smoking experiences.

Hereinafter, the detailed structure of the aerosol-generating article 150-3 and the principle of action of the heater section 140 according to the third embodiment of the present disclosure will be described.

Fig. 7 is a schematic diagram for explaining the detailed structure of the aerosol-generating article 150-3 and the principle of action of the heater section 140 according to the third embodiment of the present disclosure.

As shown in fig. 7, the aerosol-generating article 150-3 according to the present embodiment may comprise an aerosol-forming substrate portion 151, an additive holder 153 and a plurality of filter portions (or filter segments) (first filter portions 154 to third filter portions 156).

The first filter portion 154 may be located downstream of the aerosol-forming substrate portion 151. The first filter mouth 154 may provide a path of movement for an aerosol formed at the aerosol-forming substrate portion 151 and may perform a filtering or cooling function on the aerosol. As shown, the first filter house 154 may be a filter segment formed with a hollow. For example, first filter portion 154 may be a tubular cellulose acetate filter or a paper tube, although the scope of the present disclosure is not limited in this respect.

In addition, the second filter portion 155 may perform a cooling function for the aerosol. The second filter portion 155 may improve the user's smoking satisfaction by delivering an aerosol of an appropriate temperature to the user. The second filter house 155 may be formed of a structure formed with a hollow or hollow space. For example, the second filter mouth portion 155 may be a paper tube or a tubular cellulose acetate filter. However, the present disclosure is not limited thereto.

The second filter portion 155 performs a cooling function, and thus may be referred to as a "cooling portion 155" or a "cooling section 155" according to circumstances.

In addition, the third filter house 156 may correspond to the aforementioned filter house 152. Therefore, the description thereof will be omitted.

Thus far, the detailed structure of the aerosol-generating article 150-3 and the principle of operation of the heater section 140 according to the third embodiment of the present disclosure have been explained with reference to fig. 7. In the following, the detailed structure of the aerosol-generating article 150-4 according to the fourth embodiment of the present disclosure and the principle of action of the heater section 140 will be described.

Fig. 8 is a schematic diagram for explaining the detailed structure of an aerosol-generating article 150-4 and the principle of operation of the heater section 140 according to a fourth embodiment of the present disclosure.

As shown in fig. 8, an aerosol-generating article 150-4 according to the present embodiment may comprise a first filter portion 157, an aerosol-forming substrate portion 151, an additive containment portion 153, a second filter portion 158 and a third filter portion 159.

The first filter portion 157 may be located at an upstream end of the aerosol-generating article 150-4 to prevent egress of the aerosol-forming substrate portion 151 to the exterior. Furthermore, the first filter portion 157 may also prevent aerosol liquefied from the aerosol-forming substrate portion 151 from flowing to an aerosol-generating device (e.g. aerosol-generating device 150-2). Alternatively, the first filter portion 157 may also perform the function of adjusting, when the aerosol-generating article 150-4 is inserted into an aerosol-generating device (e.g. aerosol-generating device 150-2), so that the aerosol-forming substrate portion 151 is in position inside the aerosol-generating device (e.g. aerosol-generating device 150-2).

The first filter portion 157 is located at the forward end of the aerosol-forming substrate portion 151 and may therefore be referred to as a "forward filter portion 157", a "forward filter segment 157" or a "forward insert 157", as the case may be.

In addition, the second filter house 158 and the third filter house 159 may correspond to the aforementioned filter house 155 and the third filter house 156, respectively. Therefore, the description thereof will be omitted.

Thus far, the detailed structure of an aerosol-generating article 150-4 and the principle of operation of the heater section 140 according to a fourth embodiment of the present disclosure have been described with reference to fig. 8.

On the other hand, in the various embodiments described above, the flavourant added to the aerosol-forming substrate portion 151 or the additive containing portion 153 may be a flavourant sheet made into a sheet shape. The fragrance sheet can gradually release the fragrance fixed inside as it is heated, and therefore, more excellent fragrance durability can be ensured compared to the fragrant liquid. However, the specific manner of incorporation and processing of the scented sheet can vary widely.

In some embodiments, the scented sheet (10 in fig. 9) may be added in a chip form. For example, flavour chips 10 may be incorporated into the aerosol-forming substrate portion 151 in a cut-and-fill mixture. Alternatively, the fragrance sheet 10 may be added to the additive containing portion 153 in a sliced form.

In some other embodiments, as shown in fig. 9, the scented sheet 10 may be made in a rolled or folded form. For example, the fragrance sheet 10 may be added to the aerosol-forming substrate portion 151 or the additive containing portion 153 in an irregularly curled or folded form (refer to 10-1), a swirled form (refer to 10-2), a concentric circle form (refer to 10-3), or a multi-folded form (refer to 10-4; for example, a form folded in such a manner as to ensure an airflow path in the long axis direction). When the fragrance sheet 10 is added in the illustrated form, an air flow path can be ensured in the long axis direction, so that smooth air flow and appropriate inhalation resistance can be ensured. In addition, the contact area of the fragrance sheet 10 with the high-temperature airflow is increased, and thus the transfer amount of the fragrance is also increased.

In some other embodiments, the scent sheet 10 can be adapted (e.g., attached) to a wrapper of an aerosol-generating article (e.g., aerosol-generating article 150). For example, the flavour sheet 10 may be located inside a wrapper of the additive holder 153 or an adjacent segment thereof (e.g. the aerosol-forming substrate portion 151, the filter pods 152, the first filter pod 154, the third filter pod 156 to the third filter pod 159). Where the wrapper comprises a metal foil, the fragranced sheet 10 may be located on the inside of the metal foil. Alternatively, the scented sheet 10 may form at least a portion of a wrapper. For example, the fragrance sheet 10 itself may be used as (or for) a wrapping paper, or a wrapping material prepared in a form in which the fragrance sheet 10 and the wrapping paper are integrated may be used as the wrapping paper.

In the foregoing embodiments, the fragrance sheet 10 may be processed by a prescribed process. However, the specific processing format can be varied.

For example, as shown in fig. 10, the scent sheet 10 can be processed to wrinkle or fold in the long axis direction (i.e., MD direction) of an aerosol-generating article (e.g., aerosol-generating article 150). For example, the flavor sheet 10 can be wrinkled or folded by at least one of a crimping (pleating) process, a folding (folding) process, and a gathering (crimping) process. Specifically, the curling process is a process of imparting a wrinkle (crepep) to a surface of a sheet by a pressure difference and a speed difference of rollers of a curling machine, and is classified into a wet process and a dry process. The wet process is a process of soaking, softening and curling base paper by water, and then drying the base paper. The dry process refers to a drying process performed by two dryers having different temperatures from each other. Those skilled in the art are already familiar with the pleating process, the folding process, and the gathering process, and thus further description thereof will be omitted. According to the present example, a plurality of flow paths can be formed in the long axis direction of the fragrance sheet 10 by at least one of the exemplified processes, and a smooth airflow flow and an appropriate inhalation resistance can be ensured by the formed flow paths. Furthermore, the contact area of the fragrance sheet 10 with the high-temperature airflow increases, and thus the transfer amount of fragrance can also be increased.

As another example, as shown in FIG. 11, the scent sheet 10 can be processed to form a plurality of holes 101 (holes). For example, the plurality of holes 101 may be formed in the fragrance sheet 10 by a punching (punching) process. At this time, the diameter of the hole 101 may be about 0.05mm to 5mm, and preferably, may be about 0.1mm to 3mm, or about 0.2mm to 2.5mm, about 0.3mm to 2.1mm, or about 0.4mm to 1.8mm. Within the above numerical range, smooth flow of air flow and appropriate suction resistance can be ensured. Not only here, the contact area of the fragrance sheet 10 with the high-temperature airflow increases, and thus the transfer amount of the fragrance can also be increased.

On the other hand, in some embodiments, the aroma sheet 10 may be added to filter units (e.g., the second filter units 155, 158) or hollow-type filter units (e.g., the first filter units 154) that perform a cooling function. For example, the aroma patch 10 may be added to the interior of the filter house (e.g., 154, the second filter house 155, the second filter house 158) or attached to the interior wall. In this case, the flavour performance and cooling performance of the aerosol-generating article (e.g. aerosol-generating article 150-3) may be improved. In detail, since the fragrance sheet 10 absorbs heat of high temperature and releases fragrance when it comes into contact with high temperature aerosol, fragrance expression and cooling performance can be improved at the same time.

The preparation steps of the above-described fragrance sheet 10 may include: a step of preparing a liquid (e.g., slurry) sheet composition; a step of drying the prepared sheet composition. The liquid may include a liquid state, and a state in which a liquid and a solid are mixed (for example, a slurry state), among others. For example, the fragrance sheet 10 can be prepared by stretching (casting) the sheet composition on a prescribed substrate and drying the sheet composition. However, the present disclosure is not limited thereto, and specific preparation methods may vary.

The detailed composition of the sheet composition may be designed in various ways, but in some embodiments, the sheet composition may be formed by mixing a solvent such as distilled water (water) and ethanol, a polysaccharide substance (or hydrocolloid substance), and a fragrance. The fragrance sheet 10 made of the sheet composition described above has excellent fragrance retention and fragrance retention, and therefore can greatly increase the fragrance expression and fragrance durability of aerosol-generating articles (e.g., aerosol-generating article 150). Hereinafter, each constituent material constituting the sheet composition will be explained.

A solvent such as distilled water, ethanol, or the like may be a factor for adjusting the viscosity of the slurry sheet composition.

The polysaccharide substance may be a substance for covering and fixing the perfume, and may be a sheet forming agent for forming a sheet. Examples of the polysaccharide substance may include cellulose-based materials such as Hydroxypropylmethylcellulose (HPMC), methylcellulose (MC), carboxymethylcellulose (CMC), agar and the like. These cellulose-based materials have a characteristic of absorbing heat well by phase change when they come into contact with a high-temperature airflow, and therefore the fragrance sheet 10 can be used not only as a fragrance-emitting material but also as a cooling material.

In some embodiments, the sheet composition may include modified cellulose of various polysaccharide species. Herein, "modified cellulose" refers to cellulose in which a specific functional group in a molecular structure is substituted. Examples of modified cellulose may include HPMC, MC, CMC, and EC, but are not limited thereto. For example, HPMC may have a grade (grade) in the range of about 4 to 40000, depending on the ratio of hydroxypropyl and methyl (or methoxy) groups substituted and the molecular weight. Depending on the grade, the viscosity of the modified cellulose can be determined. More specifically, the physical and chemical properties of HPMC are related to the ratio of methoxy groups, the ratio of hydroxypropyl groups and molecular weight, and the types of HPMC are classified into HPMC1828, HPMC2208, HPMC2906 and HPMC2910 according to the ratio of methoxy groups to hydroxypropyl groups in the United States Pharmacopoeia (USP). Wherein the first two numbers may represent the ratio of methoxy groups and the last two numbers may represent the ratio of hydroxypropyl groups. The present inventors continuously performed experiments, and as a result, confirmed that the fragrance sheet 10 prepared from the modified cellulose-containing sheet composition is excellent in sheet physical properties and fragrance retention.

In addition, examples of the flavors may include menthol, nicotine salt, tobacco extract containing nicotine, natural plant flavors (e.g., cinnamon of stannum, sage, vanilla, chamomile, pueraria, hydrangea, lily of the valley, lavender, cardamom, clove, nutmeg, bergamot, geranium, honey essence, rose oil, lemon, orange, cinnamon, caraway, jasmine, ginger, coriander, vanilla extract, spearmint, mint, cinnamon, coffee, celery, acerola, sandalwood, cocoa, ylang, fennel, anise, licorice, carob bean, plum extract, peach extract, etc.), saccharides (e.g., glucose, fructose, isomerous sugar, caramel, etc.), cacao (powder, extract, etc.), esters (e.g., isoamyl acetate, linalyl acetate, isoamyl propionate, linalyl butyrate, etc.), ketones (e.g., menthone, ionone, damascone, ethyl maltol, etc.), alcohols (e.g., geraniol, linalool, anethole, eugenol, etc.), aldehydes (e.g., vanillin, benzaldehyde, anisaldehyde, etc.), lactones (e.g., γ -undecalactone, γ -nonalactone, etc.), animal flavors (e.g., musk, ambergris, masked palm beaver, castor bean, etc.), hydrocarbons (e.g., limonene, pinene, etc.). The perfume may be used in solid form or may be dissolved or dispersed in a suitable solvent such as propylene glycol, ethanol, benzyl alcohol or triethyl citrate. Further, a fragrance which is easily dispersed in a solvent by adding an emulsifier, for example, a hydrophobic fragrance, an oil-soluble fragrance, or the like can be used. These perfumes may be used alone or in combination. However, the scope of the present disclosure is not limited to the foregoing examples.

In some embodiments, a fragrance having a melting point of about 80 ℃ or less may be used. In this case, when the fragrance sheet 10 is contacted with an air stream of 80 ℃ or higher, the fragrance may undergo a phase change and absorb more heat, so that the cooling performance of the fragrance sheet 10 can be further improved. Given that the temperature of a heated aerosol is typically above 80 ℃, the cooling performance of most aerosol-generating articles (e.g., aerosol-generating article 150) can be effectively enhanced by the use of the above-described perfume. Furthermore, by making the phase-changed perfume volatile, the aroma performance of the aerosol-generating article (e.g., aerosol-generating article 150) can be increased. Examples of the perfume having a melting point of about 80 ℃ or less may include menthol, but are not limited thereto.

On the other hand, in some embodiments, the sheet composition may further comprise LM-pectin (low methoxyl pectin). LM-pectin is a low ester pectin or a low methoxyl pectin with a low degree of esterification, and in particular may refer to a pectin having a carboxyl group content of less than about 50% in the molecular structure. Unlike carrageenan, LM-pectin does not gel when left to cool, and therefore can reduce the viscosity of the pulp sheet composition (e.g., to the extent of about 600 to 800 cp). Further, the slurry sheet composition can be prepared without using an emulsifier, so that there can be no safety problem caused by the emulsifier.

The LM-pectin may contain less than about 50%, less than about 40%, less than about 30%, less than about 20%, or less than about 10% carboxyl groups in the molecular structure. The lower the carboxyl content in the molecular structure of the LM-pectin, the lower the viscosity of the pulp containing the LM-pectin will be.

Further, in some embodiments, the sheet composition may further comprise a bulking agent. The swelling agent may be a material that can increase the total mass (i.e., dry mass) of the components other than distilled water to increase the volume of the fragrance sheet 10 produced, but may be a material that does not affect the original function of the fragrance sheet 10. Specifically, the bulking agent can have the property of increasing the volume of the scent sheet 10 without substantially increasing the viscosity of the slurry, while not adversely affecting the flavor retention function of the scent sheet 10. Preferably, the swelling agent may be a starch, a modified starch or a starch hydrolysate. However, the present disclosure is not limited thereto.

The modified starch is selected from acetic acid starch, oxidized starch, hydroxypropyl phosphate di-starch, hydroxypropyl starch, phosphoric acid di-starch, phosphoric acid mono-starch, and phosphoric acid di-starch.

Starch hydrolysate refers to a material obtained by a process comprising the step of hydrolyzing starch. For example, the starch hydrolysate may include a material obtained by directly hydrolyzing starch (i.e., dextrin), or a material obtained by hydrolyzing starch after heat treatment (i.e., indigestible dextrin). For example, the swelling agent may be dextrin (dextrin), and more specifically, cyclodextrin (cyclodextrin).

Generally, the starch hydrolysate may be a starch hydrolysate having a DE value in the range of about 2 to about 40, preferably, a starch hydrolysate having a DE value in the range of about 2 to about 20. As the starch hydrolysate having a DE value in the range of about 2 to about 20, for example, pinedex #100 (japanese pine grain chemical industry co., ltd.), pinefiber (japanese pine grain chemical industry co., ltd.) and TK-16 (japanese pine grain chemical industry co., ltd.) can be used.

Where "DE" is an abbreviation for dextrose equivalent (dextrose equivalent), and the DE value indicates the degree of hydrolysis of starch, i.e., the saccharification rate of starch. In the present disclosure, the DE value may be a value determined by the Willstatter-Schudel method. With respect to the properties of the hydrolyzed starch (starch hydrolysate), for example, with respect to the molecular weight of the starch hydrolysate or the arrangement of the sugar molecules constituting the starch hydrolysate, each molecule of the starch hydrolysate may be different, existing in a form having a certain distribution or variation (variation). Each molecule of the starch hydrolysate may exhibit different physical properties (e.g., DE value) according to the distribution or change of the characteristics of the starch hydrolysate or the difference of the cut intervals, etc. As described above, the starch hydrolysate is a collection of molecules exhibiting different physical properties, but the measurement result (i.e., DE value) of the willstat-Schudel method is regarded as a representative value representing the degree of hydrolysis of starch.

Preferably, the starch hydrolysate may be selected from the group consisting of dextrins having a DE value of about 2 to about 5, indigestible dextrins having a DE value of about 10 to about 15 and mixtures thereof. As dextrin having a DE value of about 2 to about 5, for example, pinedex #100 (japanese songo chemical industries co., ltd.) can be used. As the indigestible dextrin having a DE value of about 10 to about 15, for example, pinefiber (japanese pine grain chemical industry co., ltd.) can be used.

Further, in some embodiments, the sheet composition may further comprise a plasticizer. The plasticizer can improve the physical properties of the sheet by adding appropriate flexibility to the fragrance sheet 10. For example, the plasticizer may include at least one of glycerin and propylene glycol, but is not limited thereto.

Further, in some embodiments, the sheet composition may further comprise an emulsifier. The emulsifier can increase the fragrance retaining amount of the fragrance sheet 10 by sufficiently mixing a fragrance having high fat solubility and a water-soluble polysaccharide substance. Examples of the emulsifier may include lecithin, but are not limited thereto.

On the other hand, the fragrance sheet 10 made of 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 the polysaccharide material and about 10 to 50 parts by weight of the scent material, based on 100 parts by weight total. Of course, the fragrance sheet 10 may further contain an appropriate amount of moisture. It was confirmed that the fragrance sheet 10 of the above composition greatly increases the fragrance expression, fragrance durability, and cooling performance of the aerosol-generating article (e.g., aerosol-generating article 150).

In some embodiments, the scented sheet 10 may comprise about 2 to about 15 parts by weight moisture, about 25 to about 90 parts by weight modified cellulose, and about 0.1 to about 60 parts by weight perfume, based on 100 parts by weight total.

Further, in some embodiments, the scented sheet 10 may comprise about 2 to about 15 parts by weight moisture, about 1 to about 60 parts by weight polysaccharide material, about 1 to about 60 parts by weight LM-pectin, and about 0.1 to about 60 parts by weight perfume, based on 100 parts by weight total weight.

In some embodiments, the plasticizer may be present 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 total weight of the scent sheet 10. For example, the fragrance sheet 10 may include about 20 to 60 parts by weight of the polysaccharide substance, about 10 to 50 parts by weight of the fragrance, and about 1 to 10 parts by weight of the plasticizer, based on 100 parts by weight of the total weight. Within the above numerical range, a sheet having appropriate flexibility (physical properties) can be formed, processing (e.g., curling, folding, etc.) of the fragrance sheet 10 becomes easy, and thus workability can be improved. For example, if a small amount of plasticizer is added, the sheet is not flexible enough to be easily broken in the process, and if a large amount of plasticizer is added, the sheet may not be formed smoothly.

Thus far, a scent sheet 10 according to some embodiments of the present disclosure has been described.

Although the embodiments of the present disclosure have been described above with reference to the drawings, it will be understood by those skilled in the art to which the present disclosure pertains that the embodiments may be embodied in other specific forms without departing from the technical spirit or essential characteristics of the present disclosure. It is therefore to be understood that the above-described embodiments are illustrative and not restrictive in all respects. The scope of the present disclosure should be determined by the claims and all explanations of technical spirit within the equivalent scope should fall within the scope of the technical idea defined by the present disclosure.
