A cover for blending one or more materials in an open topped container. The cover is adapted to close the open top during blending. The cover may have a central hole for passing the shaft of a powered blender and a peripheral opening for pouring materials from the container or into a container, and to view the progress of the mixing. Optionally, the cover may have a third opening and as a further option, a fourth opening, the third and fourth openings adapted to connect to a commercial vacuum device for evacuating dust from the container during blending. The third and fourth openings may be formed as prescored removable portions of the cover. In a further option, the third and fourth openings may be provided with close fitting removable resilient plugs. The upper surface of the cover may be inclined so that liquids flow towards the peripheral opening and into the container.
