Smoking article provided with filter

Abstract

A smoking article provided with a filter including an aerosol generating member, a filter including a filter material and one or more filter wrappers wound around an outer circumferential surface of the filter material, and an outer wrapper wound around the outer circumferential surfaces of an end part of the aerosol generating member and the filter, wherein the outer circumferential surface of the outer wrapper has an arithmetic mean roughness of less than 2.0 μm, and the filter wound with the outer wrapper has a compression recovery of 60% or more after a compression load of 2.5 N is applied to a range of a length of 10 mm in the diameter direction thereof.

What is claimed is: 
     
         1 . A smoking article provided with a filter comprising:
 an aerosol generating member;   a filter comprising a filter material and one or more filter wrappers wound around an outer circumferential surface of the filter material; and   an outer wrapper wound around the outer circumferential surfaces of an end part of the aerosol generating member and the filter,   wherein   the outer circumferential surface of the outer wrapper has an arithmetic mean roughness of less than 2.0 μm, and   the filter wound with the outer wrapper has a compression recovery of 60% or more after a compression load of 2.5 N is applied to a range of a length of 10 mm in the diameter direction thereof.   
     
     
         2 . The smoking article provided with a filter of  claim 1 , wherein the arithmetic mean roughness of the outer circumferential surface of the outer wrapper is 1.0 μm or less. 
     
     
         3 . The smoking article provided with a filter of  claim 1 , wherein a recovery angle after folded of the outer wrapper or the one or more filter wrappers is 60 degrees or more. 
     
     
         4 . The smoking article provided with a filter of  claim 3 , wherein the recovery angle after folded of the outer wrapper or the one or more filter wrappers is 100 degrees or more. 
     
     
         5 . The smoking article provided with a filter of  claim 4 , wherein the recovery angle after folded of the outer wrapper or the one or more filter wrappers is 100 degrees or more and 120 degrees or less. 
     
     
         6 . The smoking article provided with a filter of  claim 1 , wherein the outer wrapper is a sheet including a plurality of layers. 
     
     
         7 . The smoking article provided with a filter of  claim 6 , wherein the sheet including the plurality of layers comprises a base layer composed of a film containing polyolefin or polyester as a main component. 
     
     
         8 . The smoking article provided with a filter of  claim 7 , wherein the base layer is a biaxially-drawn film. 
     
     
         9 . The smoking article provided with a filter of  claim 7 , wherein the sheet including the plurality of layers further comprises a surface layer provided on one surface or both surfaces of the base layer. 
     
     
         10 . The smoking article provided with a filter of  claim 9 , wherein the surface layer contains an inorganic filler. 
     
     
         11 . The smoking article provided with a filter of  claim 1 , wherein a hardness of the filter wound with the outer wrapper is less than 90%. 
     
     
         12 . The smoking article provided with a filter of  claim 1 , wherein a basis weight of the outer wrapper is 100 g/m 2  or more. 
     
     
         13 . The smoking article provided with a filter of  claim 1 , wherein a thickness of the outer wrapper is 100 μm or more. 
     
     
         14 . The smoking article provided with a filter of  claim 1 , wherein the one or more filter wrappers are films containing polyolefin as a main component or films containing polyester as a main component. 
     
     
         15 . The smoking article provided with a filter of  claim 14 , wherein the one or more filter wrappers are biaxially-drawn films. 
     
     
         16 . The smoking article provided with a filter of  claim 14 , wherein a total basis weight of the one or more filter wrappers is 100 g/m 2  or more. 
     
     
         17 . The smoking article provided with a filter of  claim 14 , wherein a total thickness of the one or more filter wrappers is 100 μm or more.
