Abstract
The dispenser features a container in which a rotary valve operates to dispense quantities of material periodically. The valve rotates on a horizontal axis above the bottom of the dispenser container so that it is at least partly immersed in the material and, during rotation, scoops up material and retains it in one or more pockets until at a preselected angular position of the valve, an opening therein registers with an opening in the front wall of the container to discharge material. The valve has generally the shape of a truncated section of a cone and the sloping walls of the truncated-conical rim cooperate with radial walls to define one or more pockets or cavities for containing material prior to discharge.
