Vaporizer cartridge

Abstract

A cartridge includes an atomizer assembly, a reservoir, and a mouthpiece. The atomizer assembly may heat a vaporizable material to generate an inhalable vapor. The reservoir may store the vaporizable material and include a wick housing and a reservoir body. The wick housing may surround at least a portion of the atomizer assembly and form a proximal wall of the reservoir. The reservoir body may be coupled to the wick housing and form a distal wall of the reservoir. The mouthpiece may deliver the inhalable vapor.

What is claimed: 
     
         1 . A cartridge configured to operatively couple with a vaporizer, the cartridge comprising:
 a mouthpiece at a proximal end of the cartridge, the mouthpiece configured to deliver an inhalable vapor;   a reservoir configured to store a vaporizable material, the mouthpiece slidably attached to an exterior surface of a proximal end of the reservoir;   a cannula extending from a distal member of the cartridge to a proximal portion of the cartridge; and   an atomizer assembly comprising an atomizer and an atomizer wrapper;   wherein the atomizer wrapper is configured to wick vaporizable material from at least one reservoir opening to the atomizer to enable the atomizer to heat and vaporize the vaporizable material;   wherein the atomizer wrapper and the atomizer both have cylindrical shapes, the atomizer wrapper having an internal cavity with an internal diameter sized to fit an exterior diameter of the atomizer, wherein the atomizer is positioned within the internal cavity of the atomizer wrapper;   wherein the atomizer wrapper has an external diameter sized to fit an interior diameter of an interior cavity of the cannula, wherein the atomizer wrapper, including the atomizer positioned therein, is positioned within an interior cavity of the cannula; and   wherein the atomizer assembly forms an axis that is coaxially aligned with a central axis running through the cartridge and the cannula.   
     
     
         2 . The cartridge of  claim 1 , wherein the distal member comprises a first air inlet receiving a first air flow and a second air inlet receiving a second air flow, wherein the distal member combines the first air flow and the second air flow in an airflow and provides the airflow to a distal opening of the cannula, wherein the atomizer heats the vaporizable material to generate vapor which is carried in the airflow towards a proximal end of the cannula, the airflow exiting the cannula split within the mouthpiece into two flows before exiting at least two openings in the mouthpiece. 
     
     
         3 . The cartridge of  claim 1 , wherein the cannula comprises a cylindrical shape having at a proximal end of the cannula a first diameter and having at a distal end of the cannula a second diameter, wherein a mid-portion of cannula is tapered in diameter from the first diameter to the second diameter. 
     
     
         4 . The cartridge of  claim 3 , further comprising a seal including an opening, wherein the seal plugs the reservoir to prevent leakage of the vaporizable material in the reservoir and the opening is sized for the first diameter of the proximal end of the cannula. 
     
     
         5 . The cartridge of  claim 4 , wherein the seal is sized to have a first size or a second size, such that when the cartridge is assembled the first size is inserted into the reservoir to provide 0.5 grams of vaporizable material and the second size is inserted into the reservoir to provide 1.0 gram of vaporizable material. 
     
     
         6 . The cartridge of  claim 1 , wherein the atomizer comprises at least a first lead and a second lead, wherein the first lead and the second lead respectively make contact with a first receptacle in the distal member and a second receptacle in the distal member, wherein the first receptacle and the second receptacle are configured to receive power from a source of power. 
     
     
         7 . The cartridge of  claim 1  further comprising:
 at least one absorbent pad positioned within an interior volume of the mouthpiece and within a proximal end of the mouthpiece. 
 
     
     
         8 . The cartridge of  claim 1  further comprising:
 at least one absorbent pad positioned in the distal member. 
 
     
     
         9 . The cartridge of  claim 1 , wherein the atomizer comprises a nichrome wire heating element embedded in a ceramic element. 
     
     
         10 . The cartridge of  claim 1 , wherein the at least one reservoir opening comprises two reservoir openings on opposing sides of the cannula. 
     
     
         11 . The cartridge of  claim 10 , wherein the mouthpiece includes at least one notch that is configured to engage with at least one recess on the exterior surface of the reservoir to fixedly attach the mouthpiece and reservoir. 
     
     
         12 . The cartridge of  claim 1 , wherein the atomizer assembly is positioned at a base portion of the reservoir and extends into a central region of the cartridge. 
     
     
         13 . A method of manufacturing a cartridge, the method comprising:
 in response to manufacturing a cartridge configured to contain a first amount of vaporizable material, inserting a first sized silicon seal into a proximal end of a reservoir of a vaporizer cartridge; and   in response to manufacturing the cartridge configured to contain a second amount of vaporizable material, inserting a second sized silicon seal into the proximal end of the reservoir of the vaporizer cartridge.   
     
     
         14 . The method of  claim 13 , further comprising continuing with manufacturing the cartridge. 
     
     
         15 . The method of  claim 13 , wherein the first amount is 1.0 gram of vaporizable material. 
     
     
         16 . The method of  claim 15 , wherein the first sized silicon seal comprises an insertion depth of 2.2 millimeters into the reservoir. 
     
     
         17 . The method of  claim 13 , wherein the first amount is 0.5 grams of vaporizable material. 
     
     
         18 . The method of  claim 17 , wherein the first sized silicon seal comprises an insertion depth of between 7.2 and 9.2 millimeters into the reservoir. 
     
     
         19 . The method of  claim 18 , wherein the reservoir is filled with vaporizable material before the first sized silicon seal or the second sized silicon seal is inserted into the proximal end of the reservoir of the vaporizer cartridge.
