Abstract
Embodiments disclosed herein are directed to a microfluidic refill cartridge having a vent hole and nozzles on a same side of the cartridge. In one or more embodiments, the vent hole and nozzles are located on upper surfaces of the cartridge, such as on a lid that is coupled to a reservoir. In particular, the nozzles and the vent hole may be formed on a microfluidic delivery member that is secured to the lid. A single cover may be used to cover the vent hole and the nozzles. In some embodiments, the single cover may be a flexible material and may adhere to the microfluidic delivery member.
