US Patent 6964355 Dry food dispensing system

A hermetically sealable dispenser for measuring and dispensing predetermined amounts of a granular product without breakage of the product. The dispenser comprises a container which can be filled with the product, and a flexible, rotatable, paddle wheel fixed within the container. The spacing between paddles of the paddle wheel form measuring compartments. The dimensions of the paddle wheel are such that the wheel forms a hermetic seal near one end of the container. A lid is provided to seal the upper end of the container such that the product is stored in an air-tight compartment prior to dispensing.
