AbstractA revolving hair coloring chemical dispensing carousel utilizes an identical pair of rounded, generally spaced apart support plates or racks which are rotatably mounted on a stationary base member. The support racks contain a series of passageways that are sized to accommodate either a large diameter container of developer solution or a smaller diameter container of colorizing pigment solution. More particularly, each cylindrical developer and pigment solution container is formed of a generally transparent material, such as clear plastic, and includes a plunger shaft which extends upwardly from the top portion of the container. The end of the plunger shaft positioned within the container housing includes a piston which facilitates the pushing or plunging of fluid confined within the fluid reservoir area of the container housing. The bottom end of the container housing includes a valve fixture, which is preferentially biased in the closed position by a helical biasing spring. When a force great enough to overcome the downward biasing force generated by the helical biasing spring is applied to the exposed tip of the valve fixture, fluid is allowed to flow from the fluid reservoir area of the container housing, through and out of the valve fixture.
