ABSTRACT:
A container cover for sealing containers, such as cylindrical drums, has a removable protective sheet adhered thereto for maintaining the cover clean during filling and warehousing of the container. During formation of the cover, a separating agent is provided between the top surface of the container cover and the removable protective sheet. A second sealer sheet, removably adhered to the bottom cover surface, is optionally utilized to act as a gasket between the container cover and the drum. When the container is sealed with such a cover, the protective sheet may be peeled away during shipping to present a clean cover surface to the customer.
