Abstract:
1. A hair color delivery system, comprising: a flexible bottle; a cap secured to a mouth of the flexible bottle; a bi-directional valve assembly situated between the flexible bottle and the cap and secured to the bottle by the cap, the bi-directional valve assembly including: an input valve defining an input slit, the input valve extending from a first planar surface of a gasket base and including a tapered extension that extends to an entrance surface containing the input slit, thereby defining an input aperture, and an exit valve defining an exit slit, the exit valve extending from a second planar surface of the gasket base in a direction opposite to that of the input valve and including a tapered extension that extends to an exit surface containing the exit slit, thereby defining an output aperture, wherein the first and second planar surfaces are opposing surfaces of the gasket base, and wherein the exit valve is operable in response to pressure in the flexible bottle; and a delivery tube having a proximal end coupled to the output aperture of the exit valve and a distal end that extends into the flexible bottle; wherein the cap includes a nozzle fluidically coupled to the proximal end of the delivery tube by the exit valve.
