<p>A beverage can (1) having a base (10) defining a re-entrant bead (17) in which a resilient disc (50) is held captive. The maximum dimension of the disc (50) is designed to be larger than the internal diameter of the re-entrant bead (17) and thus, when the resilient disc (50) is fitted into the re-entrant bead (17), the disc (50) adopts a concave, domed shape. The degree of doming can accommodate any variance between the dimensions of the disc (50) and that of the reformed base (10) of the can (1). One or more drainage ports may be provided on the periphery of the resilient disc (50) so that any liquid trapped between the surfaces of the base (10) and the resilient disc (50) may drain.</p>
