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, to enable the seal to be detached. The seal can be attached to the neck of a bottle by a hot melt adhesive. The sheet and membrane can be stamped from a compound sheet and be of the same size. The composite portion can extend up to a line extending across a major portion of the membrane, or in another embodiment it covers a major portion of the membrane. Alternatively, the first sheet and the membrane can have a substantially common periphery in the separated portion of the sealing member forming the tab. A further embodiment provides for a sealing member that is entirely planar.
