Abstract
A cartridge configured to be releasably connectable with a housing is provided. The cartridge has a reservoir for containing a fluid composition. The reservoir includes a top surface, a bottom surface vertically opposing the top surface, and a sidewall that joins the top and bottom surfaces. The reservoir also includes a sponge disposed within the reservoir and a microfluidic die disposed adjacent to the sidewall. The fluid composition is gravity fed from the reservoir to the microfluidic die. The microfluidic die is configured to dispense the fluid composition in an upward dispensing direction in opposition to the force of gravity. The microfluidic die may be disposed at an acute angle from the interior of the cartridge and relative to the bottom surface of the reservoir.
