International Classification:

US Classification:

Abstract:

A dispensing device, having a hollow nipple-shaped stopper configured to act as a one-way valve, for use as a hair dyeing comb is provided. The nipple-shaped stopper has an aperture at its tip end. The aperture opens toward outside when the operator compresses the plastic bottle and closes when the operator releases the plastic bottle. When the aperture is in its closed position, the stopper prevents the liquid hair dye already in the conduit from flowing back to the plastic bag inside the bottle. The purpose of using the stopper here is to keep the air out of the dispensing system in order for the operator to pump the liquid dye efficiently. The stopper and a small aperture at the bottom of the plastic bottle are replacing the one-way valve currently used in many hair dye-dispensing devices. With interchangeable comb heads, the operator can choose the proper comb head for his hair type and different application purpose.
