Metering and dispensing closure

Abstract

A metering and dispensing closure for a container wherein two rotatable disks rotate in conjunction with a stationary cap member to afford accurate measuring of a powder material and dispensing of it. The disks and the container cap afford a consistent measuring of the powder material, as well as provide a variety of drive members which can be utilized with the dispensing closure.

1 . A dispensing closure for a container containing granular dispensable materials, the dispensing closure comprising:
 a cap adapted to be received on the container, the cap having an inside face, an outside face, and an aperture extending from the inside face to the outside face through the cap to allow materials within the container to be dispensed, the inside face having a generally concave shape adjacent the aperture to funnel the dispensable materials toward the aperture, the outside face of the cap having a generally planar configuration adjacent the aperture;   a first movable member positioned adjacent the inside face of the cap to selectively block the aperture in the cap, the first movable member being movable between a first position in which the aperture is blocked and a second position in which the aperture is not blocked; and   a second movable member positioned adjacent the outside face of the cap to selectively block the aperture in the cap, the second moveable member being movable between a first position in which the aperture is blocked and a second position in which the aperture is not blocked, movement of the first moveable member and the second moveable member is sequenced such that at least one of the moveable members is always blocking the aperture.
