Smoking article with improved flavor persistence and manufacturing method thereof

Abstract

Provided are a smoking article having improved flavor persistence and a manufacturing method thereof, the smoking article including: a smoking material portion: a filter portion: and a wrapper wrapping at least a portion of the smoking material portion, wherein flavor persistence of the smoking article is improved by applying a flavoring sheet including a hydrocolloid material and flavoring to the wrapper.

1 . A smoking article comprising:
 a smoking material portion;   a filter portion; and   a wrapper wrapping at least a portion of the smoking material portion, wherein a flavoring sheet including a hydrocolloid material and flavoring is applied to the wrapper.   
     
     
         2 . The smoking article of  claim 1 , wherein the flavoring sheet is used as the wrapper. 
     
     
         3 . The smoking article of  claim 1 , wherein the flavoring sheet has a thickness of about 40 μm to about 150 μm. 
     
     
         4 . The smoking article of  claim 1 , wherein the flavoring sheet is attached to an inner side of the wrapper. 
     
     
         5 . The smoking article of  claim 4 , wherein the flavoring sheet is attached to the inner side of the wrapper without an adhesive. 
     
     
         6 . The smoking article of  claim 1 , wherein at least a portion of the wrapper is made of metal foil, and the flavoring sheet is arranged on an inner side of the metal foil. 
     
     
         7 . The smoking article of  claim 1 , wherein an inner side of the wrapper is coated with a composition of the flavoring sheet. 
     
     
         8 . The smoking article of  claim 7 , wherein the composition has a coating thickness less than or equal to 70 μm. 
     
     
         9 . The smoking article of  claim 1 , wherein the hydrocolloid material includes methylcellulose. 
     
     
         10 . The smoking article of  claim 1 , wherein the hydrocolloid material includes low methoxyl pectin (LM-pectin), wherein the LM-pectin is a material including a carboxyl group of less than 50% and having a characteristic of not gelating when cooled. 
     
     
         11 . A method of manufacturing a smoking article, the method comprising:
 manufacturing a wrapping material by using a flavoring composition including a hydrocolloid material and flavoring, or by using a flavoring sheet manufactured from the flavoring composition; and   manufacturing a smoking article including a smoking material portion by wrapping at least a portion of the smoking material portion with the manufactured wrapping material.   
     
     
         12 . The method of  claim 11 , wherein the manufacturing the wrapping material comprises laminating the flavoring sheet and wrapping paper by injecting a liquid having no viscosity or adhesiveness. 
     
     
         13 . The method of  claim 11 , wherein the manufacturing the wrapping material comprises applying the flavoring composition onto wrapping paper and drying the flavoring composition.
