An apparatus for storing and dispensing particulate material, such as bird seed, employs a dispensing valve having a first disk fixedly mounted in a housing and a second disk rotatably mounted in the housing. The first disk has circumferentially spaced first apertures and the second disk has circumferentially spaced second apertures. The boundaries of the first apertures intersect the periphery of the first disk, and the boundaries of the second apertures intersect the periphery of the second disk. The second disk can be rotated to select a desired position, such as a closed position in which the first and second apertures are completely unaligned, a fully open position in which the first and second apertures are completely aligned, or a partially open position in which the first and second apertures are partially aligned.

[ That which is claimed is:] [1.] A valve comprising:a tubular housing having an interior surface and a longitudinal axis;a first disk fixedly and substantially coaxially mounted within the housing and having--a substantially circular first periphery, at least two (hereafter a number "n") circumferentially spaced first apertures of which each has a single first boundary defining the first aperture and intersecting the first periphery, and "n" peripheral first edges defining the first periphery and contacting or being immediately adjacent to the housing interior surface;a second disk rotatably and substantially coaxially mounted within the housing immediately adjacent to the first disk and having--a substantially circular second periphery, "n" circumferentially spaced second apertures of which each has a single second boundary defining the second aperture and intersecting the second periphery, and "n" peripheral second edges defining the second periphery and contacting or being immediately adjacent to the housing interior surface;a control means for rotating the second disk to enable the second disk to be set at--a closed position in which the first and second apertures are completely unaligned, a fully open position in which the first and second apertures are completely aligned, or any intermediate and partially open position between the closed and fully open positions in which the first and second apertures are partially aligned.
