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.
