Abstract

A cigarette includes a tobacco rod, a support segment located at a downstream end of the tobacco rod, a cooling segment located at a downstream end of the support segment, and a mouthpiece located at a downstream end of the cooling segment. The cigarette further includes a corrugated inner wrapper configured to wrap the mouthpiece and an outer wrapper configured to wrap the corrugated inner wrapper.

1 . A cigarette comprising:
 a tobacco rod;   a support segment located at a downstream end of the tobacco rod;   a cooling segment located at a downstream end of the support segment; and   a mouthpiece located at a downstream end of the cooling segment,   wherein the cigarette   further comprises a corrugated inner wrapper configured to wrap the mouthpiece and an outer wrapper configured to wrap the corrugated inner wrapper.   
     
     
         2 . The cigarette of  claim 1 , wherein a passage through which an aerosol passes is formed between the corrugated inner wrapper and the outer wrapper. 
     
     
         3 . The cigarette of  claim 1 , wherein a width between corrugations of the corrugated inner wrapper is 1 mm to 3 mm, and a depth of the corrugations of the corrugated inner wrapper is 0.3 mm to 1 mm. 
     
     
         4 . The cigarette of  claim 1 , wherein the corrugations of the corrugated inner wrapper are formed by a stamping roller. 
     
     
         5 . The cigarette of  claim 1 , wherein air flows into the cooling segment from the outside through perforations formed in at least a portion of the cooling segment. 
     
     
         6 . The cigarette of  claim 1 , wherein the outer wrapper wraps the cooling segment, and
 the perforations are formed through the outer wrapper and the cooling segment such that air flows into the cooling segment from the outside through the perforations.   
     
     
         7 . A cigarette comprising:
 a tobacco rod;   a first support segment located at a downstream end of the tobacco rod;   a second support segment that is located at a downstream end of the first support segment and has an inner diameter larger than an inner diameter of the first support segment; and   a mouthpiece located at a downstream end of the second support segment,   wherein the cigarette   further comprises a corrugated inner wrapper configured to wrap the mouthpiece and an outer wrapper configured to wrap the corrugated inner wrapper.   
     
     
         8 . The cigarette of  claim 7 , wherein air flows into the second support segment from the outside through perforations formed in at least a portion of the second support segment. 
     
     
         9 . The cigarette of  claim 8 , wherein the outer wrapper wraps the second support segment, and
 the perforations are formed through the outer wrapper and the second support segment such that air flows into the second support segment from the outside through the perforations.
