The suggested lid ring (2) having a first and second attaching portion as radially inner and radially outer portions and an intermediate linking portion, connecting first and second portions, The first portion having a ring surface adapted to carry a sealed foil (3) as panel, said foil having an outer ring band(3b) for sealing on the ring surface (2b). Said outer portion (2a) adapted to be seamed to an edge of a container body. The linking portion provided and configured as circumferential hinge (30). The first and second portions being tiltable relative to each other upon pressure applied to the sealed foil as panel, sealed on the ring surface of the first portion.
