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.

  • 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.

  • 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.

  • 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.
