Abstract
A fluidic dispensing device for dispensing a fluid has a body having a chamber with a perimetrical end surface. An ejection chip is attached to the body in fluid communication with the chamber. A diaphragm has a dome portion and a perimeter sealing surface. The perimeter sealing surface of the diaphragm is in sealing engagement with the perimetrical end surface of the chamber to define a fluid reservoir that contains the fluid. The diaphragm has a deflection axis that is substantially perpendicular to a plane of the perimeter sealing surface. The diaphragm has a cross-section profile that controls a deflection of the dome portion to collapse along the deflection axis in a direction that is at least one of toward or away from a plane of the perimeter sealing surface as the fluid is depleted from the fluid reservoir.
