ABSTRACT:
A void cap having a stepped configuration converging to a discharge end enhances blending action by disrupting the sliding action of the materials as they pass along the void cap. Sloped angles at each of the stepped configurations facilitate discharge of material. The void cap is particularly adapted for attachment to one or both ends of steel or fiberboard drum containers thereby changing the total volume of such containers to facilitate addition of materials and/or blending of materials.
