Cigarette

Abstract

A cigarette includes a tobacco rod and a filter rod connected to a downstream end portion of the tobacco rod. A portion of the filter rod includes a cooling portion, and the cooling portion includes sucrose as a cooling material.

1 . A cigarette comprising:
 a tobacco rod; and   a filter rod connected to a downstream end portion of the tobacco rod;   wherein a portion of the filter rod comprises a cooling portion, and the cooling portion comprises sucrose as a cooling material.   
     
     
         2 . The cigarette of  claim 1 , wherein the cooling portion comprises a first filter element at one side end portion of the cooling portion and a second filter element at the other side end portion of the cooling portion, and the first filter element and the second filter element are spaced apart by a certain distance to form a cavity between the first filter element and the second filter element, and the cooling material is in the cavity. 
     
     
         3 . The cigarette of  claim 1 , wherein the cooling material has a bead form. 
     
     
         4 . The cigarette of  claim 3 , wherein a surface of the bead-form cooling material is coated. 
     
     
         5 . The cigarette of  claim 4 , wherein fine protrusions are formed on at least a portion of the surface of the cooling material. 
     
     
         6 . The cigarette of  claim 1 , wherein the cooling material has a sheet form. 
     
     
         7 . The cigarette of  claim 6 , wherein the sheet-form cooling material is located in the cooling portion and wound such that an airflow passes through in a longitudinal direction of the cooling portion. 
     
     
         8 . The cigarette of  claim 6 , wherein the sheet-form cooling material comprises any one material of porous paper or edible film. 
     
     
         9 . The cigarette of  claim 1 , wherein the cooling material is a block form. 
     
     
         10 . The cigarette of  claim 9 , wherein the block-form cooling material has any one shape of a cylindrical shape, a tube shape, or a nine-holed briquette shape. 
     
     
         11 . The cigarette of  claim 9 , wherein at least one channel through which an airflow passes through in a longitudinal direction of the cooling portion is formed in an outer circumferential surface of the block-form cooling material. 
     
     
         12 . The cigarette of  claim 11 , wherein the at least one channel forms a regular pattern or an irregular pattern of a straight line, a curved line, a spiral, or a zigzag, and is formed on the outer circumferential surface of the cooling material. 
     
     
         13 . The cigarette of  claim 1 , wherein
 the filter rod comprises a tube portion, a cooling portion, and an acetate portion,   the tube portion is connected to a downstream end portion of the tobacco rod, the cooling portion is connected to a downstream end portion of the tube portion, and   the acetate portion is connected to a downstream end portion of the cooling portion.   
     
     
         14 . The cigarette of  claim 1 , wherein
 the filter rod comprises a cooling portion, a tube portion, and an acetate portion,   the cooling portion is connected to a downstream end portion of the tobacco rod, the tube portion is connected to a downstream end portion of the cooling portion, and   the acetate portion is connected to a downstream end portion of the tube portion.
