Smoking article

Abstract

A smoking article includes an aerosol-generating section and a filter section attached to the aerosol-generating section. The filter section contains a plurality of flavor-releasing particles each containing a water-soluble matrix containing a flavor component. The plurality of flavor-releasing particles has respective particle diameters ranging from 1 to 100 μm and has an average particle diameter of 20 μm or less.

Field of the Invention[0004]The present invention relates to a smoking article, especially a smoking article comprising a filter containing a flavor component.[0005]2. Description of the Related Art[0006]A smoking article, for example, a cigarette, is composed of various materials, such as tobacco shreds, paper, a filter, and activated carbon occasionally filled in the filter. Further, the cigarette and other smoking articles are loaded with various flavor components to create the taste and aroma peculiar to each cigarette product. In recent...

AI Technical Summary

Benefits of technology

[0009]Therefore, it is an object of the present invention to provide a smoking article that can ensure stable retention of a flavor component but immediate release of the flavor component at the time of smoking.

Problems solved by technology

However, it is likely for the cigarette with a filter having a flavor component directly incorporated therein to be unable to ensure stable flavoring because of the migration of the flavor component from the filter section to another tobacco material section due to the adsorption equilibrium within the package through the distribution stage of the cigarette product.

The cigarette with a filter containing porous particles having a flavor component adsorbed thereon cannot attain satisfactory release of the flavor component because of the incomplete desorption of the flavor component from the porous particles at the time of smoking.

However, none of these cigarettes can ensure stable retention of a flavor component during the non-smoking period but immediate release of the flavor component at the time of smoking.
