Cartridge for vaporizer device
A vaporizer cartridge is described that is configured for coupling to a vaporizer device body and containing a vaporizable material. Various embodiments of the vaporizer cartridge are described that include one or more features for maximizing a reservoir volume within the vaporizer cartridge for the containing of vaporizable material thereby increasing the output of vaporized vaporizable material from a compact cartridge configuration. Additionally, associated methods of manufacturing are described.
1. A method of manufacturing a vaporizer cartridge, comprising:
filling a first part of a volume of a mold with a first material, wherein the volume defines the vaporizer cartridge and the first part defines a reservoir housing of the vaporizer cartridge, the reservoir housing comprising a reservoir wall;
filling a second part of the volume of the mold with a second material, wherein the second part defines a mouthpiece of the vaporizer cartridge and is separate from the first part, the mouthpiece comprising a mouthpiece wall;
curing the first material and the second material;
contacting a first end of the reservoir wall with a second end of the mouthpiece wall; and
laser welding the first end of the reservoir wall to the second end of the mouthpiece wall such that an inner reservoir surface of the reservoir wall is continuous and co-planar with an inner mouthpiece surface of the mouthpiece wall, wherein the reservoir wall and the mouthpiece wall define at least a part of a reservoir chamber for containing a vaporizable material.
2. The method of claim 1 , wherein an outer reservoir surface of the reservoir wall is co-planar with an outer mouthpiece surface of the mouthpiece wall.
3. The method of claim 1 , wherein the first material is translucent.
4. The method of claim 1 , wherein the second material is opaque.
5. The method of claim 1 , wherein the first part includes a stepped portion defining a stop feature along the reservoir housing.
6. The method of claim 5 , wherein the stop feature is shaped to prevent insertion of the vaporizer cartridge into a vaporizer body past the stepped portion.
7. The method of claim 5 , wherein the stop feature includes an increase in a cross section of the reservoir housing.
8. The method of claim 2 , wherein a wall thickness of the vaporizer cartridge is substantially the same along the reservoir housing and the mouthpiece.
9. The method of claim 1 , further comprising:
filling a second mold with a third material, wherein the second mold defines an air tube assembly.
10. The method of claim 9 , further comprising laser welding the air tube assembly to at least one of the reservoir housing and the mouthpiece.
11. The method of claim 10 , further comprising coupling a seal to a port of the air tube assembly thereby fluidically sealing a reservoir chamber in the reservoir housing.
12. The method of claim 11 , further comprising delivering a vaporizable material to the reservoir chamber.
13. A vaporizer cartridge for coupling to a vaporizer body to form a vaporizer, comprising:
a reservoir housing defining a first part of a reservoir chamber, the reservoir chamber configured to contain a vaporizable material, the reservoir housing comprising a reservoir wall;
a mouthpiece comprising a mouthpiece wall, the mouthpiece wall coupled to the reservoir wall of the reservoir housing such that an inner reservoir surface of the reservoir wall is continuous and co-planar with an inner mouthpiece surface of the mouthpiece wall, wherein the mouthpiece wall defines a second part of a reservoir chamber for containing a vaporizable material; and
an air tube assembly comprising:
a wick housing portion configured to position a wicking element and a heating element in a vaporization chamber for vaporizing the vaporizable material in the vaporization chamber;
a tubing portion comprising a part of an airflow pathway that extends through the vaporization chamber and the mouthpiece thereby allowing vaporized vaporizable material to be inhaled by a user; and
a filter housing portion configured to position a filter adjacent the mouthpiece.
14. The vaporizer cartridge of claim 13 , wherein the air tube assembly is made out of a single molded part.
15. The vaporizer cartridge of claim 13 , wherein the tubing portion is made out of metal.
16. The vaporizer cartridge of claim 15 , wherein the filter housing portion and the wick housing portion is made out of a plastic material.
17. The vaporizer cartridge of claim 13 , wherein an outer reservoir surface of the reservoir wall is co-planar with an outer mouthpiece surface of the mouthpiece wall.
18. The vaporizer cartridge of claim 13 , wherein a first end of the reservoir wall is laser welded to a second end of the mouthpiece wall.
