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.
Claims10
A void device for a container, said cap having a rigid generally conical shape and having an opening at each end, the larger end of said cap being of sufficient size to be coupled to an open end of a container that contains material and the smaller end being for discharge of the material, said larger end including an axis, the inner surface of the side walls of said cap being comprised of a plurality of side wall portions that are parallel to said axis and a plurality of angular side wall portions, some of said angular side wall portions being disposed at an angle of about 45.degree. relative to said axis, some of said side wall portions being disposed at an angle of about 60.degree. relative to said axis, said angular portions being disposed between said annular portions with said portions angled at 60.degree. being further from said large end than said portions angled at 45.degree. and the juncture of said wall portions is rounded so that said angled side wall portions and said parallel side wall portions cooperate with each other and with said rounded junctures to disrupt the flow of material and cause it to change direction thereby intermixing it as it is discharged from the container through said void cap.
A void cap device comprising a means for containing material to be mixed and first and second void caps, said void caps each having a generally conical shape and being open at each end, the larger end of said caps being coupled to the opposite ends of said containing means and the smaller ends being adapted to discharge material when not closed, the inner surfaces of the side walls of said cap being comprised of a plurality of side wall portions that are parallel to the axis of the larger end of said cap and a plurality of side wall portions that are disposed at an acute angle relative to said axis and at least one of said smaller ends is laterally displaced from said axis.
