Tobacco product, and filter for tobacco product

Abstract

This filter for a tobacco product has: a fine-powder-containing article in which there is clumped a raw powder including a taste component and/or an aroma component, the fine-powder-containing article being formed into a powder by the application of force; a cavity in which the fine-powder-containing article is disposed; and a suction port filter part installed downstream of the cavity, the suction port filter part enabling communication between the cavity and an end of a suction port and having formed along the axial direction thereof a fine powder supply path for supplying fine powder from the cavity to the end of the suction port. The fine powder supply path includes a central connection part positioned at the center of a cross-section of the suction port filter part, and a plurality of hole parts extending in mutually different directions from the central connection part toward the outer periphery of the cross-section.

What is claimed is: 
     
         1 . A smoking article comprising:
 a tobacco rod including tobacco shreds; and   a filter coupled to an end portion of the tobacco rod via a tipping paper, wherein   the filter includes:   a powder content that includes a lump of base powder including at least either one of a taste component or a flavoring component and is turned into powder by application of an external force;   a cavity where the powder content is accommodated; and   a mouthpiece filter unit that is located continuously at a downstream side of the cavity, and is provided with a powder supply path formed along an axial direction for allowing a mouthpiece end to communicate with the cavity and supplying the powder from the cavity to the mouthpiece end, and   in a cross section of the mouthpiece filter unit, the powder supply path has a central connection portion located at a central side of the cross section of the mouthpiece filter unit and a plurality of holes that extend in mutually different directions from the central connection portion toward an outer peripheral side of the cross section.   
     
     
         2 . The smoking article according to  claim 1 , wherein each of the holes of the powder supply path has a relatively large opening width at an outer peripheral region located at the outer peripheral side of the cross section of the mouthpiece filter unit as compared with at a central region located at the central side of the cross section. 
     
     
         3 . The smoking article according to  claim 1 , wherein the powder supply path has the holes that are at least three and not more than five in number. 
     
     
         4 . The smoking article according to  claim 1 , wherein the plurality of holes of the powder supply path radially extend from the central connection portion. 
     
     
         5 . The smoking article according to  claim 1 , wherein in the cross section of the mouthpiece filter unit, a filter fiber that provides the mouthpiece filter unit is interposed between a distal end of each of the holes of the powder supply path and a wrapping paper of the mouthpiece filter unit. 
     
     
         6 . A filter for a smoking article, the filter comprising:
 a powder content that includes a lump of base powder including at least either one of a taste component or a flavoring component and is turned into powder by application of an external force;   a cavity where the powder content is accommodated; and   a mouthpiece filter unit that is located continuously at a downstream side of the cavity, and is provided with a powder supply path formed along an axial direction for allowing a mouthpiece end to communicate with the cavity and supplying the powder from the cavity to the mouthpiece end, and   in a cross section of the mouthpiece filter unit, the powder supply path has a central connection portion located at a central side of the cross section of the mouthpiece filter unit and a plurality of holes that extend in mutually different directions from the central connection portion toward an outer peripheral side of the cross section.
