ABSTRACT:
A spreader for distributing particulate material, particularly adapted for use as both a package for particulates and as a disposable spreader, comprises a dispenser, a pair of wheels mounted at opposite ends of the dispenser and a handle for advancing the spreader along a given path as the dispenser rotates. The dispenser has inner and outer chambers, the inner chamber adapted to act as a reservoir for particulate material, the outer chamber adapted to provide a circumferential passageway for particulate material passing from the inner chamber to the exterior of the spreader. A one-way valve arrangement in the passageway restricts particulate flow to the exterior when the dispenser is rotated in one direction but permits flow when rotated in the opposite direction.
