Abstract

Vaporization devices and methods of operating them. In particular, described herein arc vaporizer cartridges for controlling the power applied to a resistive heater.

What is claimed is: 
     
         1 . A cartridge for a vaporization device, the cartridge comprising:
 a flattened body having a long axis and a short axis;   a mouthpiece at a proximal end of the flattened body;   a reservoir within the flattened body, the reservoir configured to hold a vaporizable material;   a resistive heater comprising a pair of plates extending in the long axis, a wick extending between the pair of plates, and a resistive heating element directly in contact with the pair of plates and with the wick, wherein the wick is configured to contact the vaporizable material from the reservoir; and   a pair of exposed flat contact tabs integrally formed from the plates and folded over an outer surface of a distal end of the cartridge and configured to complete a circuit with the vaporization device when the cartridge is inserted into the vaporization device.   
     
     
         2 . The cartridge of  claim 1 , wherein the flattened body is transparent. 
     
     
         3 . The cartridge of  claim 1 , wherein the pair of exposed contact tabs are configured to mate with a pair of electrical contacts comprising pogo pins in a cartridge receptacle of the vaporization device to complete the circuit. 
     
     
         4 . The cartridge of  claim 1 , wherein the resistive heating element is wound around the wick. 
     
     
         5 . The cartridge of  claim 1 , wherein the resistive heater comprises a condensation chamber. 
     
     
         6 . The cartridge of  claim 1 , further wherein the mouthpiece is fitted onto the proximal end of the flattened body. 
     
     
         7 . The cartridge of  claim 1 , further wherein the mouthpiece is coupled to the flattened body with a snap-fit coupling. 
     
     
         8 . The cartridge of  claim 1 , further comprising an air inlet passage. 
     
     
         9 . The cartridge of  claim 1 , further comprising a channel integral to an exterior surface, wherein the channel forms a first side of an air inlet passage. 
     
     
         10 . The cartridge of  claim 1 , wherein the resistive heating element is attached to the pair of plates. 
     
     
         11 . The cartridge of  claim 1 , wherein the mouthpiece is positioned at least partially over the reservoir and has a notch providing a view into the reservoir. 
     
     
         12 . A cartridge for a vaporization device, the cartridge comprising:
 a flattened body having a long axis and a short axis;   a reservoir within the flattened body holding a vaporizable material;   a mouthpiece at a proximal end of the flattened body;   a resistive heater comprising a pair of plates extending in the long axis and a wick extending between the pair of plates, and a resistive heating element directly in contact with the pair of plates and in thermal contact with the wick, wherein the wick contacts the vaporizable material in the reservoir;   a pair of exposed flat contact tabs integrally formed from the pair of plates, extending from the resistive heater, and folded over an outer surface of a distal end of the flattened body and configured to complete a circuit with the vaporization device when the cartridge is inserted into the vaporization device.   
     
     
         13 . The cartridge of  claim 12 , wherein the flattened body is transparent. 
     
     
         14 . The cartridge of  claim 12 , wherein the resistive heater comprises a condensation chamber. 
     
     
         15 . The cartridge of  claim 12 , wherein the resistive heater encloses a first end of the cartridge. 
     
     
         16 . The cartridge of  claim 12 , further wherein the mouthpiece is fitted onto the proximal end of the flattened body. 
     
     
         17 . The cartridge of  claim 12 , further wherein the mouthpiece is coupled to the flattened body with a snap-fit coupling. 
     
     
         18 . The cartridge of  claim 12 , further comprising a channel integral to an exterior surface, wherein the channel forms a first side of an air inlet passage. 
     
     
         19 . The cartridge of  claim 12 , wherein the resistive heating element is attached to the pair of plates. 
     
     
         20 . A cartridge for a vaporization device, the cartridge comprising:
 a flattened body having a long axis and a short axis;   a reservoir holding a liquid vaporizable material within the flattened body;   a resistive heater at a distal end of the flattened body, the resistive heater comprising a pair of plates extending in the long axis, a wick extending between the pair of plates, and a resistive heating element directly in contact with the pair of plates and in thermal contact with the wick, wherein the wick contacts the vaporizable material in the reservoir;   a pair of exposed flat contact tabs integrally formed from the plates, extending from the resistive heater, and folded over an outer surface of the distal end of the flattened body, the pair of exposed flat contact tabs configured to complete a circuit with the vaporization device when the cartridge is inserted into the vaporization device; and   a mouthpiece at least partially over the reservoir and having a notch providing a view into the reservoir.
