Claims
- 1. A method of forming an openable closure for a container comprising folding a blank of material to form an inner lid element having a flat bottom and a frame along at least two sides of said bottom, placing said inner lid element into an open end of a filled container with the bottom of the inner lid element facing into the container and the frame releasably bearing against the inner surfaces of the side walls of the container, joining a blank of material for an outer lid element with the frame of the inner lid element and joining the outer lid element to the container with a separable connection to enable separation of the outer lid element from the container together with removal of the entire inner lid element from the container to provide access to the interior of the container.
- 2. A method as claimed in claim 1 comprising folding at least one flap on the blank of the outer lid element to a position against the outer surface of at least one of the side walls of the container and fixing said flap to said one side wall to provide said separable connection of the outer lid element and the container.
- 3. A method as claimed in claim 1 wherein said inner lid element is freely and separably contained, in entirety, within said container.
- 4. A method as claimed in claim 3 wherein said frame of said inner lid element is formed with a U-shaped configuration in cross-section to provide tight engagement with said container when bearing against the inner surfaces of the side walls thereof, the inner lid element being removable from the container, in entirety, by lifting the inner lid element from the container when the outer lid element is separated from the container.
- 5. A method as claimed in claim 1 wherein the container is formed with a perimetral rim which limits the degree of penetration of the inner lid element into the container.
- 6. A method as claimed in claim 5 wherein said frame of said inner lid element is wholly contained within the container.
- 7. A method as claimed in claim 1 wherein said frame of said inner lid element is installed on the container by overlapping one of the walls of the container and being snap-engaged therewith.
- 8. A method as claimed in claim 7 further comprising adhesively joining the frame of the inner lid element with the outer surface of the wall of the container which it overlaps.
- 9. A method as claimed in claim 8 wherein the joining of the outer lid element to the inner lid element is effected by adhesively joining said outer lid element to said inner lid element at the location where the inner lid element overlaps the outer surface of the wall of the container.
- 10. A method as claimed in claim 1 wherein said frame of said inner lid element is installed in the container and overlaps one of the walls of the container, and the outer lid element is joined to the inner lid element adhesively at the location where the inner lid element overlaps the wall of the container.
- 11. A method as claimed in claim 1 wherein the outer lid element is joined to the inner lid element by adhesives.
- 12. A method as claimed in claim 11 wherein said outer lid element is hingeably connected to the container such that separation of the outer lid element is effected by pivotably raising the outer lid element, the inner lid element being pivotably raised with said outer lid element.
- 13. A method as claimed in claim 12 comprising effecting the separable connection of the outer lid element with the container via the inner lid element.
- 14. A method as claimed in claim 12 comprising effecting reclosure of the container by pivotably lowering the outer lid element, together with the inner lid element, onto the container.
