Definitions
- the present disclosure relates to an aerosol-generating article with improved cooling performance and flavor persistence and a method of producing the same, and more particularly, to an aerosol-generating article which includes a cooling part and is capable of simultaneously improving aerosol cooling performance of the cooling part and improving flavor persistence of the article, thus ensuring high smoking satisfaction, and a method of producing the article.
- the two factors that greatly influence the smoking satisfaction of the heating-type cigarettes are aerosol cooling performance and flavor persistence.
- a heating-type cigarette includes a cooling part to allow a user to inhale an aerosol having an appropriate temperature, and in a case in which the performance of the cooling part is degraded, a high-temperature aerosol may be discharged as it is and smoking satisfaction of the user may be decreased.
- a process of flavoring a heating-type cigarette is performed by directly adding (e.g., spraying) a flavoring liquid to a tobacco material or filter plug.
- a flavoring method has a problem in that, since most of the flavor is expressed at an early stage of smoking, the flavor expressing property is rapidly degraded toward the end of smoking, and thus the smoking satisfaction of the user may be decreased. Further, when a flavoring liquid is added in an excessive amount, a problem in which a wrapper wrapping around the tobacco material or filter plug becomes wet and contaminated may occur.
- Some embodiments of the present disclosure are directed to providing an aerosol-generating article with improved cooling performance and flavor persistence and a method of producing the same.
- Some embodiments of the present disclosure provide an aerosol-generating article including an aerosol-forming substrate part and a cooling part disposed downstream of the aerosol-forming substrate part to cool an aerosol formed in the aerosol-forming substrate part, wherein a sheet-type material may be disposed in a rolled or folded form in the cooling part.
- the sheet-type material may include a polysaccharide material and a flavoring.
- the sheet-type material may be pleated or folded in a longitudinal direction.
- a plurality of holes may be formed in the sheet-type material.
- resistance to draw of the cooling part may be in a range of 0.1 mmH 2 O/mm to 3.5 mmH 2 O/mm.
- the sheet-type material may include, with respect to a total of 100 parts by weight, 20 to 60 parts by weight of the polysaccharide material and 20 to 50 parts by weight of the flavoring.
- the sheet-type material may further include 1 to 10 parts by weight of a plasticizer.
- a thickness of the sheet-type material may be 150 ⁇ m or less.
- a melting point of the flavoring may be 80 °C or lower.
- a sheet-type material including a polysaccharide material and a flavoring can be disposed in (applied to) a cooling part of an aerosol-generating article.
- the polysaccharide material may undergo a phase change and absorb a large amount of heat, and simultaneously, the flavoring covered by the polysaccharide material may be slowly discharged. Accordingly, cooling performance and flavor persistence of the aerosol-generating article can be improved, and smoking satisfaction of a user can be significantly improved.
- the sheet-type material may be disposed in a rolled or folded form in the cooling part.
- a smooth airflow can be ensured in a longitudinal direction, and an area coming into contact with the airflow is increased, thus further improving performance of the cooling part.
- pleats may be formed in the longitudinal direction in the sheet-type material.
- a smooth airflow can be ensured in the longitudinal direction, and an area coming into contact with the airflow is increased, thus further improving the performance of the cooling part.
- processes such as rolling and folding can be easily performed.
- a plurality of holes may be formed in the sheet-type material.
- a smooth airflow can be ensured through the holes formed, and an area coming into contact with the airflow is increased, thus further improving the performance of the cooling part.
- a flavoring whose melting point is 80 °C or lower may be included in the sheet-type material.
- the flavoring may undergo a phase change and further absorb the heat.
- the performance of the cooling part can be further improved.
- an aerosol heating temperature of typical heating-type cigarette products is 80 °C or higher
- the use of the flavoring described above can effectively improve aerosol cooling performance of most aerosol-generating articles.
- the phase-changed flavoring is easily volatilized, the flavor expressing property of the aerosol-generating article can also be improved.
- the cooling part may be designed to have a shorter length as compared to conventional cooling parts, and accordingly, the degree of design freedom of the aerosol-generating article can be improved.
- first, second, A, B, (a), and (b) may be used. Such terms are only used for distinguishing one component from another component, and the essence, order, sequence, or the like of the corresponding component is not limited by the terms.
- a certain component is described as being “connected,” “coupled,” or “linked” to another component, it should be understood that, although the component may be directly connected or linked to the other component, still another component may also be “connected,” “coupled,” or “linked” between the two components.
- aerosol-forming substrate may refer to a material that is able to form an aerosol.
- the aerosol may include a volatile compound.
- the aerosol-forming substrate may be a solid or liquid.
- solid aerosol-forming substrates may include solid materials based on tobacco raw materials such as reconstituted tobacco leaves, shredded tobacco, and reconstituted tobacco
- liquid aerosol-forming substrates may include liquid compositions based on nicotine, tobacco extracts, and/or various flavoring agents.
- the scope of the present disclosure is not limited to the above-listed examples.
- aerosol generation device may refer to a device that generates an aerosol using an aerosol-forming substrate in order to generate an aerosol that can be inhaled directly into the user's lungs through the user's mouth.
- aerosol-generating article may refer to an article that is able to generate an aerosol.
- the aerosol-generating article may include an aerosol-forming substrate.
- a typical example of the aerosol-generating article may include a cigarette, but the scope of the present disclosure is not limited thereto.
- puff refers to inhalation by a user, and the inhalation may be a situation in which a user draws smoke into his or her oral cavity, nasal cavity, or lungs through the mouth or nose.
- longitudinal direction may refer to a direction corresponding to a longitudinal axis of an aerosol-generating article.
- sheet may refer to a thin layer component whose width and length are substantially larger than a thickness thereof.
- sheet may be interchangeably used with the term “web” or “film” in the art.
- FIG. 1 is an exemplary view schematically illustrating an aerosol-generating article 100 according to some embodiments of the present disclosure.
- the aerosol-generating article 100 may include an aerosol-forming substrate part 110, a cooling part 120, a filter part 130, and a wrapper 140.
- the aerosol-generating article 100 may further include general-purpose components other than the components illustrated in FIG. 1 .
- FIG. 1 only schematically illustrates some examples of aerosol-generating articles according to various embodiments of the present disclosure, and a specific structure of the aerosol-generating article may be changed from that illustrated in FIG. 1 .
- FIGS. 5 to 8 may be referenced for examples of aerosol-generating articles having different structures.
- each component of the aerosol-generating article 100 will be described.
- the aerosol-forming substrate part 110 may serve to form an aerosol.
- the aerosol-forming substrate part 110 may include an aerosol-forming substrate and may form an aerosol using the aerosol-forming substrate.
- the aerosol-forming substrate part 110 may form an aerosol when heated by an aerosol generation device (e.g., 1000 of FIG. 9 ).
- the formed aerosol may be delivered to the oral region of a user via the cooling part 120 and the filter part 130 by a puff.
- the aerosol-forming substrate part 110 may be disposed upstream of the cooling part 120 and abut an upstream end of the cooling part 120.
- the aerosol-forming substrate part 110 may further include the wrapper 140 that wraps around the aerosol-forming substrate.
- the aerosol-forming substrate part 110 is produced in the form of a rod and thus may also be referred to as "aerosol-forming rod 110" or “tobacco rod 110" in some cases. Alternatively, the aerosol-forming substrate part 110 may also be referred to as "medium portion 110" in some cases.
- the cooling part 120 may serve to cool the aerosol formed in the aerosol-forming substrate part 110.
- the cooling part 120 may allow an aerosol having an appropriate temperature to be delivered to the user, thus improving smoking satisfaction of the user.
- the cooling part 120 may further include the wrapper 140 that wraps around a cooling structure.
- a sheet-type material 10 may be disposed in (applied to) the cooling part 120.
- the sheet-type material 10 is a material in the form of a sheet that contains a polysaccharide material and a flavoring, and by using the property of the polysaccharide material that undergoes a phase change and absorbs a large amount of heat, the sheet-type material 10 may improve performance of the cooling part 120. Further, since the flavoring covered by the polysaccharide material is slowly expressed according to the phase change of the polysaccharide material, flavor persistence of the aerosol-generating article 100 may also be improved.
- the sheet-type material 10 may serve as a cooling material as well as a flavor expressing material in the cooling part 120. Materials constituting the sheet-type material 10 and a method of producing the same will be described in detail below.

- a sheet having appropriate flexibility (physical property) may be formed, and since processing (e.g., crimping, rolling, folding, etc.) of the flavoring sheet 10 is easy, workability may be improved. For example, in a case in which the amount of added plasticizer is too small, flexibility of the sheet may be decreased and thus the sheet may be easily damaged during processes, and in a case in which the amount of added plasticizer is too large, the sheet may not be formed well.
