Tipping paper to which technology for reducing tobacco smell on fingers is applied and smoking article including the same, and method of producing the tipping paper

Abstract

An embodiment of the present invention provides a tipping paper for smoking articles. The tipping paper includes a fragrance carrier including a fragrance material and a carrier material, the carrier material includes the fragrance material, and the fragrance material included in the carrier material is disseminated from the tipping paper in response to moisture, saliva, or friction, and the carrier material is a material soluble in ethanol.

1 . A method of producing a tipping paper, the method comprising:
 adding a carrier material to ethanol to obtain a first solution and stirring the first solution;   adding a fragrance material to the first solution in which the carrier material is added to the ethanol to obtain a second solution and stirring the second solution;   adding a binder to the second solution, in which the carrier material and the fragrance material are added to the ethanol, to obtain a third solution and stirring the third solution; and   printing the third solution, in which the carrier material, the fragrance material, and the binder are added to the ethanol to be used as a fragrance carrier ink, on the tipping paper.   
     
     
         2 . The method of  claim 1 , wherein the printing the third solution further comprises adding microcapsules to the fragrance carrier ink to obtain a fourth solution and stirring the fourth solution,
 wherein a core of each microcapsule is an ethanol-based fragrance and a shell of each microcapsule is polyvinyl alcohol (PVA), and   the microcapsules are produced by stirring the ethanol-based fragrance and the PVA at room temperature, adding a cross-linking agent to a fifth solution in which the ethanol-based fragrance and the PVA are stirred and stirring the fifth solution at a temperature higher than or equal to 60° C. and lower than or equal to 100° C., and cooling the fifth solution in which the ethanol-based fragrance, the PVA, and the cross-linking agent are stirred.   
     
     
         3 . The method of  claim 1 , wherein the carrier material comprises 2-hydroxypropyl-β-cyclodextrin. 
     
     
         4 . The method of  claim 1 , wherein the fragrance material comprises one or more materials of vanillin and ethyl vanillin. 
     
     
         5 . The method of  claim 4 , wherein:
 a weight ratio of the vanillin with respect to a total weight of the fragrance material is in a range of 15% to 25%, and a weight ratio of the ethyl vanillin with respect to the total weight of the fragrance material is in a range of 5% to 15%.   
     
     
         6 . The method of  claim 1 , wherein:
 a weight ratio of the fragrance material with respect to a total weight of the fragrance carrier ink is greater than 0% and lower than or equal to 1.5%, and   a weight ratio of the carrier material with respect to the total weight of the fragrance carrier ink is greater than 0% and lower than or equal to 15%.   
     
     
         7 . The method of  claim 1 , wherein:
 a weight ratio of the binder with respect to a total weight of the fragrance carrier ink is greater than 5% and lower than or equal to 10%.   
     
     
         8 . The method of  claim 1 , wherein:
 the binder is a polymer material that is soluble in ethanol and has a molecular weight in a range of 3,000 to 20,000 and a glass transition temperature in a range of 60° C. to 90° C.   
     
     
         9 . The method of  claim 1 , wherein:
 the carrier material is insoluble in water and isopropyl alcohol, and   the carrier material is soluble in ethanol.
