Patent attributes
Cartridges for vaporizer devices are provided. In one exemplary embodiment, a cartridge can include a reservoir housing that includes a reservoir chamber configured to contain a vaporizable material and first and second orifices each in fluid communication with the reservoir chamber. The first orifice is configured to allow at least a portion of the vaporizable material to be withdrawn from the reservoir chamber in response to generation of a first pressure differential across the first orifice that exceeds a first predetermined threshold pressure differential. The second orifice is configured to allow a portion of ambient air that is outside the reservoir housing to enter the reservoir chamber in response to generation of a second pressure differential across the second orifice that exceeds a second predetermined threshold pressure differential during the withdrawal of the vaporizable material from the reservoir chamber. Vaporizer devices and methods are also provided.
