A sealable container cover includes both an elastic edge and an adhesive edge for sealing the container cover to the wall or walls of a container. The elastic material around the expandable opening of the container cover may be attached directly to the edge of the cover, housed by a hem created at the edge of the cover, or housed by an additional piece of film or other material attached at the edge of the cover.

What is claimed is: 1. A container cover, comprising: a flexible film having an outer surface and an inner surface; elastic material coupled to a periphery of the film and extending in a continuous loop around the periphery of the film, the elastic material forming a primary closure member for attachment of the cover to a container; and an adhesive layer disposed on the inner surface of the film, the adhesive layer being interior to and separate from the elastic material, the adhesive layer forming a continuous loop around the film and forming a secondary closure member for attachment of the cover to a container. 2. The container cover of claim 1, wherein the flexible film is a plastic material. 3. The container cover of claim 1, wherein the flexible film is perforated. 4. The container cover of claim 1, wherein the elastic material is sewn directly to the film. 5. The container cover of claim 1, wherein the elastic material is glued directly to the film. 6. The container cover of claim 1, wherein the elastic material is heat sealed directly to the film. 7. The container cover of claim 1, wherein the elastic material is housed within a fold at the periphery of the film. 8. The container cover of claim 1, wherein a cover layer is attached to the periphery of the film to form a compartment sized to receive the elastic material. 9. The container cover of claim 1, further including a flexible covering provided over the adhesive material, the flexible covering being removable prior to use. 10. The container cover of claim 1, wherein the adhesive material is pressure-sensitive. 11. A method of covering a container, comprising the steps of: providing a flexible film having an outer surface and an inner surface, elastic material coupled to a periphery of the film to define an expandable opening, and an adhesive layer disposed on the inner surface of the film, the adhesive layer being interior to and separate from the elastic material, the elastic material forming a continuous loop around the film and forming a primary closure member for attachment of the cover to a container, the adhesive layer forming a continuous loop around the film and forming a secondary closure member for attachment of the cover to a container; expanding the opening to a size sufficient to receive the container; placing the film over the container so that the opening surrounds a wall of the container; releasing the opening so that the elastic material engages the container wall with the primary closure member; and pressing the outer surface of the film in an area opposite the adhesive layer inwardly toward the container wall, thereby creating a seal between the film and the container wall with the secondary closure member. 12. The method of claim 11, further including removing a flexible covering from the adhesive layer prior to covering the container.
