Definitions

  • Common cigarettes and electric heating tobacco products include a filter having functions of adjusting the amount of air that enters when aerosol and the like are inhaled, lessening the flavor, reducing nicotine and tar, and the like.
  • a technique in which an additive is added to a filter in order to impart a function other than the above-described basic functions is known.
  • the ability of the adsorbent including the fat to remove specific hydrocarbon and the effect of the adsorbent to reduce oil stain are as disclosed in International Publication No. 2018/008608 .
  • the ability to remove specific hydrocarbon is an ability produced since the adsorbent includes the fat.
  • the effect to reduce oil stain is an effect produced since the fat has a melting point of 50°C or more.
  • the conditions of the filter are described below.
  • the mode in which the filter includes the above adsorbent is not limited.
  • the filter may include the adsorbent in any mode.
  • the structure of the filter is not limited.
  • the filter include a plain filter including a single filter segment and a multi-segment filter including a plurality of filter segments, such as a dual filter or a triple filter.
  • the above adsorbent may be included in at least one of the segments.
  • the adsorbent may be added to the filter so as to disperse all over the entire filter uniformly, may be added at an intended position in a lump, and may be added to a space interposed between filter segments.
  • the filter may have a section, such as a cavity (e.g., center-hole) or recess, formed therein such that a cross section of the filter taken in the circumferential direction is hollow (i.e., has a hollow space).
  • a cavity e.g., center-hole
  • recess formed therein such that a cross section of the filter taken in the circumferential direction is hollow (i.e., has a hollow space).
  • the airflow resistance of the filter per 120-mm length of the filter when the filter is heated at 100°C for 10 minutes is commonly, but not limited to, 50 mmWG (water gage) or more and 300 mmWG or less, is preferably 70 mmWG or more and 280 mmWG or less, and is more preferably 90 mmWG or more and 260 mmWG or less.
  • the first tobacco filler may include a flavoring agent.
  • the type of the flavoring agent is not limited. In order to impart a good flavor, the following flavoring agents may be used: acetanisole, acetophenone, acetylpyrazine, 2-acetylthiazole, an alfalfa extract, amyl alcohol, amyl butyrate, trans-anethole, a star anise oil, an apple juice, a Peru balsam oil, a beeswax absolute, benzaldehyde, benzoin resinoid, benzyl alcohol, benzyl benzoate, benzyl phenylacetate, benzyl propionate, 2,3-butanedione, 2-butanol, butyl butyrate, butyric acid, caramel, a cardamom oil, a carob absolute, ⁇ -carotene, a carrot juice, L-carvone, ⁇ -caryophyllene, a
  • Examples of a substrate for the sheets include a tobacco material, such as a tobacco powder.
  • a tobacco material is particularly preferable.
  • Tobacco sheets that include substrate sheets composed of a tobacco material and a component capable of generating a flavor which is deposited on the substrate sheets as needed are preferable.
  • the internal structure of the cooling segment desirably has a large total surface area. Therefore, in a preferable embodiment, the cooling segment may be formed of a thin sheet material that has been wrinkled in order to form channels and then pleated, gathered, and folded. The larger the number of folds or pleats per unit volume of the component, the larger the total surface area of the cooling segment.
  • the diameter of the perforations is preferably 100 ⁇ m or more and 1000 ⁇ m or less and is more preferably 300 ⁇ m or more and 800 ⁇ m or less.
  • the perforations are preferably substantially circular or substantially oval. In the case where the perforations are substantially oval, the term "diameter" refers to a major-axis length.
  • the tip paper is not limited and may be common paper. Examples thereof include paper including pulp as a principal component.
  • the tip paper may be paper made of a wood pulp, such as a conifer wood pulp or a broadleaf wood pulp, or paper made of pulp mixture further including nonwood pulp commonly used for producing tip paper for tobacco items, such as a flax pulp, a cannabis pulp, a sisal hemp pulp, or an esparto pulp.
  • the above pulp materials may be used alone. Alternatively, a plurality of types of pulp materials may be used in combination at any ratio.
  • the shape of the tip paper is not limited and may be, for example, square or rectangular.
  • the flavor produced by an electric heating tobacco product is likely to degrade in later stages of use.
  • the degradation of flavor which may occur in later stages of use can be limited compared with the case where a common filter is used.
  • the heater member of the electric heating device produces heat due to the control performed by the control unit.
  • the electric heating tobacco product is an inside heating-type electric heating tobacco product
  • the tabular heater, the pillar-shaped heater, and the cone-shaped heater can be used.
  • the sheet-like heater, the tabular heater, and the tubular heater can be used.
