ABSTRACT:
A hair-tinting implement comprises a container containing a tinting medium, and a workhead provided with two tinting-medium outlets. The container is generally cylindrical, and is made of resiliently-deformable plastics material. The workhead is attached to one end of the container, and is provided with a pair of internal ducts which connect the interior of the container to the outlets. The other end of the container is closed off by a screw cap. An air-intake valve is provided in the screw cap, the air-intake valve being such as to open when the pressure in the container is less than that outside the container. The air-intake valve is constituted by a plurality of valve openings passing through the screw cap, a valve seat formed on the interior surface of the screw cap, and a resiliently-deformable valve closure member which overlies the valve seat and the valve openings.
