A funnel is designed for attachment to one end of a cylindrical drum and includes an inclined funnel surface depending toward a discharge opening passing through an opening adjacent one edge of the drum. Around the inclined surface is a raised flange and outside the flange is a depending skirt. The skirt is attached to the peripheral wall of the drum by screw fasteners. The flange includes a plurality of recesses with each recess defining a horizontal bottom wall which sits on the end of the drum. A lid is also provided for engagement onto the funnel and comprises a dome central section and a peripheral depending section for engaging over the outer surface of the flange of the funnel. The peripheral section includes a plurality of recesses corresponding to the recesses of the flange to act as a friction fit within the recesses to hold the lid in place.
