Abstract
A dispensing device for use as a hair dye applicator is provided having a manifold having a first end configured to receive liquid dye and an inside surface and an outside surface. The manifold has a conduit communicating with the inside surface and the first end which provides fluid communication between the first end and at least one orifice extending from the inside surface to the outside surface. The manifold further includes a first lip and a second lip on the outside surface with the first lip surrounding the orifice and the second lip surrounding the first lip. The manifold further includes a flexible fluid dispensing member having an inside surface and an outside surface and a plurality of apertures passing from the inside surface to the outside surface that presents the dye to the hair, the inside surface of the member contacting the outside surface of the manifold including the first and second lips such that a resilient seal is formed until the dye is forced through the orifices when the member allows the dye to pass over the first lip and through the plurality of apertures.
