Closure

A closure (1) for a container, the closure (1) comprising a metal annular component (2), the annular component (2) having a sealing panel (3) adapted to support a lid (9) of peelable lidding material bonded to the sealing panel (3) to thereby define an annular bond region, the annular component (2) terminating in an inner peripheral curl (4) extending from the sealing panel (3) to define an access opening for a container, the sealing panel (3) being adjustably tiltable ( ) relative to a plane (5) generally defined by the access opening under the action of a differential pressure (P) acting over the area of the lid (3), characterised in that the sealing panel (3) has radial inner and outer annular portions (3a, 3b), the radial inner portion (3a) extending from the radial inside edge of the sealing panel for one quarter of the width of the sealing panel (3), and the radial outer portion extending for the remaining width of the sealing panel (3), the radial inner portion (3a) of the sealing panel (3) configured with a circumferential hinge (10a, 10b), the circumferential hinge (10a, 10b) provided as one or more annular thinned bands (10a, 10b) formed in the radial inner portion (3a).
