A cover assembly including a frame and a lid for placement over the open top of a container. The frame has a circumferential side which fits snugly around the sides of the open container and a relatively short inwardly extending lip along its upper edge to support the frame on the rim of the container. The lip has an inner edge defining an access opening. A portion of the inner edge is set back away from the inside surface of the container so the lip at such portion does not interfere with removal of the contents. A lid, supported by a recessed lid sealing surface on the lip, covers the access opening. The container is typically a rectangular cardboard box having flaps folded up and back down along the sides of the box. The box typically contains a product in a plastic bag conforming to the interior of the box. The bag is sufficiently tall so that the bag opening can be drawn out and cover the downwardly folded flaps. The frame is placed over the open top of the box so that the sides of the frame lie snugly against the outwardly and downwardly folded bag and flaps. Convenient access to the product is thereby achieved.
