A heater assembly comprises a container including a cylindrical portion that forms a chamber in which a flavor generating article is contained, and a heater arranged in a peripheral surface of the cylindrical portion. The container includes a first channel extending along a longitudinal direction of the cylindrical portion and located adjacently to the chamber in a direction intersecting with the longitudinal direction of the cylindrical portion, and a second channel extending through the chamber along the longitudinal direction of the cylindrical portion. The first channel is in communication with the second channel.

Heater assembly and container

A tobacco rod for a flavor inhaler includes a cylindrical container, and a flavor source including tobacco filled in the cylindrical container, in which the flavor source is filled in such a manner as to form voids over a longitudinal direction, and the following relationship is satisfied: S/T≤17%, wherein T represents an area of all voids present in a cross-section of the flavor source orthogonal to the longitudinal direction of the cylindrical container, and S represents a total area of voids each having an area of 800000 μmor more in the cross-section.

A heater assembly includes a container including a cylindrical portion that forms a chamber in which a flavor generating article is contained, and a heater arranged in a peripheral surface of the cylindrical portion. The container includes a first channel extending along a longitudinal direction of the cylindrical portion and located adjacently to the chamber in a direction intersecting with the longitudinal direction of the cylindrical portion, and a second channel extending through the chamber along the longitudinal direction of the cylindrical portion. The first channel is in communication with the second channel.

A flavor inhaler includes a tubular holder that extends from a mouthpiece end toward a distal end, a flavor source that is provided in the holder, and a combustion type heat source that is provided at the distal end, and includes a protruding portion protruding from the distal end and a flavorant carried on the protruding portion.

Flavor inhaler and method of manufacturing combustion type heat source

A method of manufacturing a flavor source includes: a step A of adding a basic substance to a tobacco raw material; a step B of heating the tobacco raw material added with the basic substance and releasing an inhaling flavor component into a vapor phase from the tobacco raw material; a step C of collecting the inhaling flavor component released into the vapor phase in the step B; a step D of washing a tobacco residue being the tobacco raw material obtained after the inhaling flavor component is released in the step B, with a washing solvent; a step E of pulverizing or cutting the tobacco residue obtained after being washed in the step D; and a step F of adding the inhaling flavor component collected in the step C to the tobacco residue obtained after pulverized or cut in the step E.

Flavor source manufacturing method

A portable package including an inhaling flavor product including a flavor base material configured by a non-tobacco material, a tobacco raw material that has undergone an alkali treatment and emits an inhaling flavor component as a vapor phase, and a container portion that contains the tobacco raw material and the flavor base material, wherein the container portion limits a movement of at least one of the tobacco raw material and the flavor base material so as to maintain the tobacco raw material and the flavor base material in a non-contacting state, and the tobacco raw material and the flavor base material are arranged within a same space constructed by the container portion.

Method for producing flavor source and package

A method for producing a flavor source that supports an inhaling flavor component contained in a tobacco raw material, comprises: step A of performing an alkali treatment on the tobacco raw material; and step B of arranging an alkali-treated tobacco raw material and a flavor base material configured by non-tobacco material within a same space in such a way that the alkali-treated tobacco raw material and the flavor base material are maintained in a non-contacting state, thereby inducing the flavor base material to support the inhaling flavor component emitted as a vapor phase from the tobacco raw material.

A non-combustion-type flavor inhaler is provided with: a heat source which has a plate-like shape having a pair of main surfaces; a flavor generation source having a plate-like shape having a pair of main surfaces; and a holder for receiving both the heat source and the flavor generation source. The heat source and the flavor generation source are stacked on each other within the holder in such a manner that one of the main surfaces of the heat source and one of the main surfaces of the flavor generation source face each other. The flavor generation source has: an introduction region for introducing air into the flavor generation source; and a delivery region for delivering air from the inside of the flavor generation source. The introduction region and the delivery region are provided on the surfaces of the flavor generation source, which are other than the main surface which faces the heat source.

Non-burning type flavor inhaler

The production process comprises a step (A) in which an alkali-treated tobacco source is heated to make the tobacco source release a flavoring ingredient into a gas phase, a step (B) in which the flavoring ingredient released into the gas phase is brought into contact with a given solvent which is a liquid substance at ordinary temperature, thereby trapping the flavoring ingredient in the given solvent, and a step (C) in which the given solvent is added to a constituent element.

Manufacturing method of composition element of item including flavor component, and composition element of item, including flavor component

An oral tobacco composition in which sensations to the throat and esophagus that are characteristic of raw tobacco are selectively removed, and a production method thereof are provided. Provided is an oral tobacco composition in which the ratio of total content of one or more of citric acid, malic acid, succinic acid, acetic acid and formic acid to the nicotine content (A/N) is 1.30 or less.

Oral tobacco composition and production method thereof

An oral tobacco composition is provided which has a 0.06 or greater ratio (A/N) of the total amount of carboxylic acid with 6 or fewer carbon atoms to the nicotine content, and which has a 20 ng or lower TSNA content per 1 mg of nicotine.

A chewable oral tobacco composition () including a tobacco raw material for eluting a tobacco component and a gum base comprises: a first gum portion () including the tobacco raw material and a first gum base; and a second gum portion () including a second gum base. The second gum portion does not include the tobacco raw material or includes the tobacco raw material in an amount less than an amount of the tobacco raw material included in the first gum portion. A weight of the first gum base is 0.3 g or more. Wt. % of the first gum base is 50 wt. % or more when wt. % of the first gum portion is 100 wt. %. Total wt. % of the first gum base and the second gum base is 50 wt. % or less when wt. % of the oral tobacco composition is 100 wt. %.

Oral tobacco composition

A non-combustion-type flavor inhaler containing a heat source and a holding member for detachably holding the heat source. The heat source includes a latent heat storage material containing a sugar alcohol of four or more carbons atoms.
