A hopper for use with a hollow cylindrical container open at one end. The open container end has an exposed edge. The hopper comprises a plurality of at least two partial hoppers, the partial hoppers extending generally at right angles to the axis of the container and being disposed one below the other. All partial hoppers are secured together, each partial hopper having an outer periphery of the same shape as the periphery of the open container end. At least the uppermost partial hopper has its peripheral edge secured to the exposed edge of the open container end. All partial hoppers have a common opening spaced inwardly from the peripheries of the partial hoppers and have a common center aligned with the axis of the container.
