 wherein the slanted surface of the conically shaped alignment element comprises at least a first groove enabling a flow of evaporated vaporizable material. 
 
   
     
     
         2 . The aerosol generating device according to  claim 1 , further comprising 
 a vaporizable material releasing means configured to enable the vaporizable material to flow from the vaporizable material capsule into a space located between a surface of the conically shaped alignment element and the conically shaped heating element at a time of mating.   
     
     
         3 . The aerosol generating device according to  claim 2  , wherein the vaporizable material capsule further comprises 
 a mesh structure located on the slanted surface of the conically shaped alignment element and configured to receive the vaporizable material by capillarity and enabling an evaporation of vaporizable material when heated. 
 
     
     
         4 . The aerosol generating device according to  claim 1 , wherein 
 the slanted surface of the conically shaped heating element further comprises at least a second groove enabling a flow of evaporated vaporizable material.   
     
     
         5 . The aerosol generating device of any one of  claims 1 to 2  and  4 , further comprising 
 a mesh structure located adjacently to the slanted surface of the conically shaped heating element and configured to receive the vaporizable material by capillarity. 
 
     
     
         6 . The aerosol generating device of any one of  claims 1 to 5 , wherein 
 the conical shape of any of the heating element and alignment element is any one of the list comprising a cone, a frusto-cone, a bullet, a frusto-bullet, an ogival shape, a frusto-ogival shape.   
     
     
         7 . The aerosol generating device according to any one of  claims 1 to 6 , further comprising 
 a body element configured to house a power source for the heat source, and   an attaching means configured to attach the conically shaped heating element to the body element.   
     
     
         8 . The aerosol generating device of  claim 5 , wherein 
 the attaching means is further configured to removably attach the conically shaped heating element to the body element.   
     
     
         9 . A vaporizable material capsule for an aerosol generating device, comprising a reservoir containing a charge of vaporizable material, the capsule further comprising
 a conically shaped alignment element configured to mate with a corresponding conically shaped heating element, and   a mesh structure located on a wall of the conically shaped alignment element and configured to receive vaporizable material from the reservoir by capillarity and enabling an evaporation of vaporizable material when heated by said conically shaped heating element and wherein,   a slanted surface of the conically shaped alignment element comprises at least a groove enabling a flow of evaporated vaporizable material.   
     
     
         10 . The vaporizable material capsule according to of  claim 9  wherein 
 the conically shaped heating element is part of the vaporizable material capsule and comprises electrical connectors to connect said conically shaped heating element to a power source of an aerosol generating device. 
 
     
     
         11 . The vaporizable material capsule according any one of  claims 9  and  10 , wherein 
 the conically shaped heating element comprises at least a groove enabling a flow of evaporated vaporizable material.
