1. A cartridge for a vaporizer device, the cartridge comprising:
a reservoir housing including a reservoir chamber configured to contain a vaporizable material;
a first orifice extending through a first wall of the reservoir housing and in fluid communication with the reservoir chamber, the first orifice being configured to allow at least a portion of the vaporizable material to be withdrawn from the reservoir chamber in response to generation of a first pressure differential across the first orifice that exceeds a first predetermined threshold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; and
a second orifice extending through a second wall of the reservoir housing and in fluid communication with the reservoir chamber, the second orifice being 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.
