Tobacco Product for Oral Use

Abstract

The present invention relates to a flavoured tobacco product for oral use comprising matrices, wherein at least one matrix comprises tobacco, and essentially all flavourants are comprised in matrices not containing tobacco.

1 . A flavoured oral tobacco product, comprising;
 at least two matrices, including:
 at least one matrix that comprises tobacco; and 
 at least one matrix that comprises flavourants but not tobacco, and wherein all tobacco-containing matrices are substantially free from flavourants. 
   
     
     
         2 . The flavoured tobacco product according to  claim 1 , wherein the at least two matrices are formed as layers. 
     
     
         3 . The flavoured tobacco product according to  claim 2 , wherein the layers are in contact with each other. 
     
     
         4 . The flavoured tobacco product according to  claim 1 , wherein the tobacco is ground tobacco. 
     
     
         5 . The flavoured tobacco product according to  claim 4 , wherein the ground tobacco has an average particle size of less than 1 mm. 
     
     
         6 . The tobacco product according to  claim 2 , wherein the average thickness of one individual layer is less than 500 μm. 
     
     
         7 . The tobacco product according to  claim 2 , wherein a surface of the layer comprising tobacco not contacted by another layer has an average surface roughness Ra less than 0.005 μm. 
     
     
         8 . The flavoured tobacco product according to  claim 1 , wherein the product is a film comprising at least two matrices in the form of layers. 
     
     
         9 . A method for producing a flavoured oral tobacco product, comprising:
 casting at least one tobacco-containing matrix; and   casting at least one flavourant-containing matrix, wherein the at least one flavourant-containing matrix comprises flavourants but not tobacco, and wherein all tobacco-containing matrices are substantially free from flavourants.   
     
     
         10 . The method according to  claim 9 , wherein the at least one tobacco-containing matrix is cast on a support. 
     
     
         11 . The method according to  claim 10 , wherein the roughness Ra of the support is less than 0.005 μm. 
     
     
         12 . The method according to  claim 10 , wherein the at least one flavourant-containing matrix is cast on the at least one tobacco-containing matrix. 
     
     
         13 . The method according to  claim 9 , wherein the matrices are formed as layers. 
     
     
         14 . The method according to  claim 13 , wherein the layers are in contact with each other. 
     
     
         15 . The method according to  claim 9 , wherein the tobacco is ground tobacco. 
     
     
         16 . The method according to  claim 15 , wherein the ground tobacco has an average particle size of less than 1 mm. 
     
     
         17 . The method according to 13, wherein the average thickness of one individual layer is less than 500 μm. 
     
     
         18 . The method according to  claim 13 , wherein a surface of the layer comprising tobacco not contacted by another layer has an average surface roughness Ra less than 0.005 μm.
