Flavor filler and flavor inhaler

Abstract

The present invention provides a flavor filler for a flavor inhaler, the flavor filler including: porous cellulose particles having a porosity of at least 40%; and flavor layers carried on the outer surfaces of the porous cellulose particles and containing particles containing flavor components.

What is claimed is: 
     
         1 . A flavor filler for a flavor inhaler comprising:
 porous cellulose particles each having a porosity of 40% or more; and   a flavor layer carried on an outer surface of each of the porous cellulose particles and including flavor component-containing particles.   
     
     
         2 . The flavor filler according to  claim 1 , wherein the flavor component-containing particles are tobacco particles. 
     
     
         3 . The flavor filler according to  claim 1 , wherein the flavor component-containing particles are flavorant particles. 
     
     
         4 . The flavor filler according to  claim 1 , wherein the porous cellulose particles each have a porosity of 50% or more. 
     
     
         5 . The flavor filler according to  claim 1 , wherein each of the porous cellulose particles has a plurality of pores extending radially from a center of each of the porous cellulose particles toward the outer surface thereof. 
     
     
         6 . The flavor filler according to  claim 1 , wherein the flavor component-containing particles have an average particle diameter larger than an average pore diameter of the porous cellulose particles. 
     
     
         7 . The flavor filler according to  claim 1 , wherein the flavor layer exists in a larger amount from a center of each of the porous cellulose particles toward the outer surface thereof. 
     
     
         8 . The flavor filler according to  claim 1 , wherein the porous cellulose particles have an average particle diameter of 300 to 2000 μm. 
     
     
         9 . The flavor filler according to  claim 1 , wherein the porous cellulose particles have an average pore diameter of 0.3 to 1000 μm. 
     
     
         10 . The flavor filler according to  claim 1 , wherein the flavor component-containing particles have an average particle diameter of 0.3 to 1000 μm. 
     
     
         11 . The flavor filler according to  claim 1 , further comprising a barrier layer on the flavor layer. 
     
     
         12 . The flavor filler according to  claim 11 , wherein the barrier layer includes a binder but is free from a flavor-contributing substance. 
     
     
         13 . The flavor filler according to  claim 11 , wherein the barrier layer includes a flavor-contributing substance that provides a flavor different from a flavor of the flavor component-containing particles included in the flavor layer. 
     
     
         14 . The flavor filler according to  claim 13 , wherein the flavor component-containing particles are first tobacco particles, and the flavor-contributing substance is either second tobacco particles different from the first tobacco particles or flavorant particles. 
     
     
         15 . The flavor filler according to  claim 13 , wherein the flavor component-containing particles are first flavorant particles, and the flavor-contributing substance is either tobacco particles or second flavorant particles different from the first flavorant particles. 
     
     
         16 . A flavor inhaler comprising the flavor filler according to  claim 1 .
