The invention concerns a device (3) for closing a container (B) comprising a sealing disc (2) capable of being sealed, bonded or locked on the edge (12) of the neck (1) of the container (B) projecting radially outside the neck. It further comprises a cap (4) capable of being mounted on the neck (1) and provided with an inner protrusion for applying on the sealing disc (2) a thrust load in a direction for spacing apart the disc (2) relative to the neck (1). Said inner protrusion is formed by a tab (412) integral with the cap (4) and folded down towards the base (413) of the cap, generally tapering and converging (a) towards the said base (413).
