Abstract
A cartridge that is releasably connectable with a housing of a microfluidic delivery device is provided. The cartridge has a reservoir for containing a fluid composition and a microfluidic die in fluid communication with the reservoir. The microfluidic die is configured to dispense substantially all of the fluid composition in a horizontal direction or downward direction relative to horizontal. The cartridge also includes an air flow channel disposed below the reservoir. The air flow channel extends from a fan to an air outlet. The air flow channel comprises a first region disposed adjacent to a fan, a second region disposed adjacent to the air outlet, and a third region joining the first and second regions. At least the second region is angled upward to the air outlet, relative to horizontal.
