A Liquid Substance Storing Container for an Aerosol Generating Device

Abstract

A liquid substance storing container for an aerosol generating device includes a porous body for storing liquid substance. The porous body includes a closed internal cavity further storing a volume of the liquid substance. The aerosol generating device including the liquid substance storing container may be used as an e-cigarette.

1 . A liquid substance storing container for an aerosol generating device, comprising a porous body for storing liquid substance, wherein said porous body includes a closed internal cavity surrounded by walls of the porous body, said closed internal cavity further storing liquid substance by forming a closed pocket. 
     
     
         2 . The A-liquid substance storing container according to  claim 1 , wherein said porous body is adapted to absorb a volume of liquid substance and to retain said volume of liquid substance until vaporized. 
     
     
         3 . The A-liquid substance storing container according to  claim 1 , wherein the porous body has an open-cell structure. 
     
     
         4 . The liquid substance storing container according to  claim 3 , wherein the open-cell structure of the porous body is adapted to retain the liquid substance in the closed internal cavity in a leak-proof manner when said porous body is maintained below a threshold temperature of 50° C. 
     
     
         5 . The A-liquid substance storing container according to  claim 4 , wherein the open-cell structure of the porous body is adapted to release the liquid substance from the closed internal cavity into the porous body by capillary action when said porous body is heated at or above said threshold temperature. 
     
     
         6 . The A-liquid substance storing container according to  claim 5 , wherein the open-cell structure of the porous body is adapted to release, through an outer surface of said porous body, a vaporized liquid substance when said porous body is heated at or above said threshold temperature. 
     
     
         7 . The liquid substance storing container according to  claim 3 , wherein the pore size of the open-cell structure of said porous body ranges between 0.5 to 100 micrometers. 
     
     
         8 . The liquid substance storing container according to  claim 1 , wherein said porous body is made of porous ceramic, sintered metal, sintered glass or alumina. 
     
     
         9 . The liquid substance storing container according to  claim 1 , wherein said porous body takes the shape of a disk, a cylinder, a hexagonal prism, or sphere. 
     
     
         10 . The liquid substance storing container according to  claim 1 , wherein said porous body takes the shape of a hollow cylinder or a hollow truncated cone. 
     
     
         11 . The liquid substance storing container according to  claim 9 , wherein said closed internal cavity has a three-dimensional shape homothetic to a shape of said porous body. 
     
     
         12 . The liquid substance storing container according to  claim 11 , wherein the three-dimensional shape of the closed internal cavity is concentric with the shape of said porous body. 
     
     
         13 . An aerosol generating device comprising a liquid substance storing container according to  claim 1 ; and a heater adapted to heat said porous body at or above a threshold temperature of 50° C. 
     
     
         14 . The aerosol generating device according to  claim 13 , wherein said heater is adapted to heat an outer surface of said porous body. 
     
     
         15 . The aerosol generating device according to  claim 13 , wherein said porous body has a hollow shape, said heater adapted to heat an inner surface of the hollow porous body. 
     
     
         16 . The liquid substance storing container according to  claim 10 , wherein said closed internal cavity has a three-dimensional shape homothetic to a shape of said porous body.
