Cartridges for Vaporizer Devices

Abstract

Cartridges for vaporizer devices are provided. In one exemplary embodiment, the cartridge can include a reservoir housing having at least one inner container that is configured to hold a vaporizable material, and a vaporization chamber in communication with the reservoir housing and including at least one wicking element configured to draw the vaporizable material from the at least one inner container to the vaporization chamber to be vaporized by a heating element, in which the at least one inner container is substantially sealed to the at least one wicking element, and wherein the at least one inner container is configured to collapse as the vaporizable material is withdrawn therefrom. Vaporizer devices are also provided.

What is claimed is: 
     
         1 . A cartridge for a vaporizer device, the cartridge comprising:
 a reservoir housing having at least one inner container that is configured to hold a vaporizable material; and   a vaporization chamber in communication with the reservoir housing and including at least one wicking element configured to draw the vaporizable material from the at least one inner container to the vaporization chamber to be vaporized by a heating element;   wherein the at least one inner container is substantially sealed to the at least one wicking element, and wherein the at least one inner container is configured to collapse as the vaporizable material is withdrawn therefrom.   
     
     
         2 . The cartridge of  claim 1 , wherein the collapsing of the at least one inner container substantially prevents a headspace vacuum from forming as the vaporizable material is being withdrawn from the at least one inner container. 
     
     
         3 . The cartridge of  claim 1 , further comprising at least one vent extending through a wall of the reservoir housing, the at least one vent allowing ambient air to pass therethrough and into the reservoir housing such that a pressure equilibrium is substantially maintained within the reservoir housing as the vaporizable material is being withdrawn from the at least one inner container. 
     
     
         4 . The cartridge of  claim 1 , wherein the vaporization chamber is defined by at least one sidewall of the reservoir housing. 
     
     
         5 . The cartridge of  claim 1 , wherein the vaporization chamber is defined by at least one wall that is coated with or formed of a hydrophobic material. 
     
     
         6 . The cartridge of  claim 1 , wherein the vaporization chamber is defined by at least one wall that is configured to allow at least a portion of airflow to pass therethrough and into the vaporization chamber. 
     
     
         7 . The cartridge of  claim 1 , wherein the wicking element is formed of one or more porous materials. 
     
     
         8 . The cartridge of  claim 1 , wherein the reservoir housing includes a first reservoir chamber and a second reservoir chamber, and wherein each of the first reservoir chamber and the second reservoir chamber has at least one of the at least one inner container disposed therein. 
     
     
         9 . The cartridge of  claim 8 , wherein the vaporization chamber is positioned between the first reservoir chamber and the second reservoir chamber. 
     
     
         10 . A vaporizer device, comprising:
 a vaporizer body;   a cartridge that is selectively coupled to and removable from the vaporizer body, the cartridge including a reservoir housing having at least one inner container that is configured to hold a vaporizable material, and a vaporization chamber in communication with the reservoir housing, the vaporization chamber including at least one wicking element configured to draw the vaporizable material from the at least one inner container to the vaporization chamber to be vaporized by a heating element;   wherein the at least one inner container is substantially sealed to the at least one wicking element, and wherein the at least one inner container is configured to collapse as the vaporizable material is withdrawn therefrom.   
     
     
         11 . The device of  claim 10 , wherein the vaporizer body includes a power source. 
     
     
         12 . The device of  claim 10 , wherein the collapsing of the at least one inner container substantially prevents a headspace vacuum from forming as the vaporizable material is being withdrawn from the at least one inner container. 
     
     
         13 . The device of  claim 10 , further comprising at least one hole that extends through a wall of the reservoir housing to allow ambient air to pass therethrough and into the reservoir housing such that a pressure equilibrium is substantially maintained within the reservoir housing as the vaporizable material is being withdrawn from the at least one inner container. 
     
     
         14 . The device of  claim 10 , wherein the vaporization chamber is defined by at least one sidewall of the reservoir housing. 
     
     
         15 . The device of  claim 10 , wherein the vaporization chamber is defined by at least one wall that is coated with or formed of a hydrophobic material. 
     
     
         16 . The device of  claim 10 , wherein the vaporization chamber is defined by at least one wall that is configured to allow at least a portion of airflow to pass therethrough and into the vaporization chamber. 
     
     
         17 . The device of  claim 10 , wherein the wicking element is formed of one or more porous materials. 
     
     
         18 . The device of  claim 10 , wherein the reservoir housing includes a first reservoir chamber and a second reservoir chamber, and wherein each of the first reservoir chamber and the second reservoir chamber has at least one of the at least one inner container disposed therein. 
     
     
         19 . The device of  claim 18 , wherein the vaporization chamber is positioned between the first reservoir chamber and the second reservoir chamber.
