  • Patent number: 9889670
    Abstract: A fluidic dispensing device has a body that includes a base wall having an exterior base surface, and an interior perimetrical wall that extends from the base wall to define a chamber. The interior perimetrical wall has a perimetrical end surface. The body has an exterior wall extending away from the base wall. The exterior wall has a chip mounting surface defining a first plane, the base wall being oriented along a second plane, the first plane being orthogonal to the second plane. An ejection chip is mounted to the chip mounting surface of the body. A diaphragm is engaged with the perimetrical end surface of the chamber to define a fluid reservoir. A lid is attached to the body, with the diaphragm interposed between the lid and the body. The body and the lid define a split at a juncture of the lid and the body.
