Abstract:
1. A device for vaporizing volatile constituents of various substances comprising: a) an outer vessel having an inside surface, an outside surface, an open proximal end and a closed distal end; said distal end having a heating area comprised of a material that can withstand heat required to vaporize the volatile constituents; b) an inner vessel having an inside surface, an outside surface, both open distal and proximal ends extending within the outer vessel in a concentric manner so as to leave a generally annular space between the outside surface of the inner vessel and the inside surface of the outer vessel over a majority of the length of the outer vessel; when so positioned, the inner and outer vessels together define a portion of an operative pathway for air; c) an air intake vent only in a region at the proximate end of the outer vessel with no vent at the distal end of the outer vessel, that provides a path for ambient air to enter into the annular space between the vessels, thereby comprising the start of the operative pathway; the pathway proceeding through the annular space to an end region, the end region being closed and having a solid air-impervious surface said end region being the closed distal end of the outer vessel, and further to then proceed into the open distal end of the inner vessel and then through the inner vessel to the open proximal end of the inner vessel; further, the air intake vent being sufficiently distant from the heating area such that fumes from a heat source providing heat to the heating area are not substantially drawn into the intake vent; and still further, within the inner vessel having a partition forming at least a partial separation of the distal portion from the proximal portion of the inner vessel, the partition suitable to positionally retain a solid material to be vaporized.
