Heat-not-burn device and flavor carrier

Abstract

A flavor carrier for an aerosol-generating device includes an outer housing extending in a longitudinal direction, an inner housing extending in the longitudinal direction, and a flavor chamber between the outer housing and the inner housing. The outer housing includes at least one outer housing perforation defined in a wall of the outer housing. The inner housing includes at least one inner housing perforation defined in a wall of the inner housing. The flavor chamber is configured to contain a flavoring material.

         13 . The aerosol generating device of  claim 1 , wherein the plurality of inner housing perforations is arranged in at least one column. 
     
     
         14 . The aerosol generating device of  claim 1 , further comprising:
 an adapter configured to fit with a portion of the flavor carrier, the adapter being formed of one or more materials including a polymer, a metal, or both a polymer and a metal, the adapter being impermeable to aerosol.   
     
     
         15 . The aerosol generating device of  claim 1 , wherein the plurality of outer housing perforations is aligned with the plurality of inner housing perforations. 
     
     
         16 . The aerosol generating device of  claim 1 , wherein the plurality of outer housing perforations is not aligned with the plurality of inner housing perforations. 
     
     
         17 . A flavor carrier comprising:
 an outer housing extending in a longitudinal direction, the outer housing defining a plurality of outer housing perforations;   an inner housing extending in the longitudinal direction and defining a plurality of inner housing perforations, the inner housing coaxial with the outer housing, the outer housing and the inner housing defining a flavor chamber, the flavor chamber configured to contain a flavoring material;   a cover at a first end of the outer housing; and   a gasket at a second end of the outer housing.   
     
     
         18 . The flavor carrier of  claim 17 , wherein the cover defines a channel therein, the channel in fluid communication with an air passage defined by the inner housing. 
     
     
         19 . The flavor carrier of  claim 17 , wherein
