Abstract (en)
[origin: WO2021076657A2] Microfluidic features regulate the flow of fluids in a cartridge for a vaporizer device. The microfluidic features prevent leaks of liquid vaporizable material and enhance the functioning of the cartridge when there is a differential pressure between a storage chamber containing the liquid vaporizable material and ambient conditions outside the cartridge. Related systems, apparatuses, and processes, are also described.
