Patent ID: 7997280

Claim:
A device for vaporizing volatile constituents of a substance the device comprising: an elongate outer vessel having an inner surface, an outer surface, a proximal end and a closed distal end, said closed distal end formed by a heating body comprising a material that can withstand heat required to vaporize said volatile constituents, said proximal end formed by a venting body; an elongate inner vessel having an inner passage dimensioned to receive the substance an outer surface and open distal and proximal ends and being insertable into said elongate outer vessel and extending within the heating body and the venting body so as to leave a space between adjacent walls of said elongate inner vessel and said heating and venting bodies, and a space between the inner vessel open distal end and the outer vessel closed distal end; one or more body vents located on the venting body away from the heating body for admitting atmospheric air along an airflow pathway formed by the space between the inner surface of the elongate outer vessel and the outer surface of the elongate inner vessel, the space between the distal ends of the elongate inner and outer vessels the inner passage, and the proximal end of the elongate inner vessel; wherein the elongate outer vessel further comprises an elongate shield configured to protect the heating body and prevent inadvertent contact with the heating body; and wherein the elongate shield further comprises one or more shield vents.
