Abstract
A sealing member for a container has a membrane, e.g., aluminum foil, and a first sheet, e.g. polyester, part of which is bonded to the membrane. The other part of the sheet is free, so as to form a tab having one of a number of possible profiles, to enable the sealing member to be detached as a single unit. At least part of the periphery of the tab is within the periphery of the membrane, to facilitate grasping of the tab. The first sheet and the membrane or foil may have a common periphery where they are bonded together.
