Abstract
Vaporizer cartridges and vaporizer apparatuses, and methods for making, using and delivering vapor to a user, that are leak-resistant for use with cannabinoids. In particular, described herein are leak-resistant vaporizer cartridges and apparatuses adapted for use with oil-based vaporizable materials including cannabis oils.
Claims30
A vaporizer cartridge comprising:
- a cartridge body comprising a proximal body end and a distal body end opposite the proximal body end;
- a mouthpiece coupled to the proximal body end, wherein the mouthpiece comprises an outlet;
- a reservoir comprising an internal volume at least partially defined by the cartridge body, wherein the internal volume is configured to hold a vaporizable material;
- a first reservoir seal configured to cover a first reservoir opening exposing the internal volume of the reservoir;
- a second reservoir seal configured to cover a second reservoir opening exposing the internal volume of the reservoir, wherein the first reservoir seal and the second reservoir seal are positioned within an interior of the mouthpiece;
- a bottom cover comprising a bottom portion positioned distally relative to the cartridge body, wherein the bottom portion comprises at least a first air opening;
- a first cartridge electrical contact configured to contact a first body electrical contact on a vaporizer body;
- a second cartridge electrical contact configured to contact a second body electrical contact on the vaporizer body;
- and
- a vaporization chamber comprising:
- a heating element configured to heat the vaporizable material from the reservoir to generate an aerosol
- a wicking material comprising ceramic;
- a housing piece configured to house at least a portion of the wicking material, wherein the housing piece comprises a housing opening into which at least the portion of the wicking material passes into the housing piece;
- and
- an air tube configured to deliver the aerosol to the mouthpiece.
