Abstract: A lid (1) for closing a can having a collar, the lid having a bottom face (2) provided with an annular sealing gasket (4) bearing against said collar when the lid (1) is in the closed state, and being provided with fastener means (14) for fastening the lid (1) to the can, which fastener means (14) comprise at least two catches (141, 142, 143) disposed about the sealing gasket (4) and having an active fastener portion (1411, 1421, 1431) that projects towards the center of the lid (1), and that is positionable under an external radial peripheral rim of the can when a movable one (143) of the catches is in a closer position in which it is closer to the other catches (141, 142).

Abstract: A lid (2) for closing a container (4) of liquid, the lid being provided with a spindle passageway (20) enabling an elongate body (30) of a stirrer member (3) for stirring the liquid to pass through the lid (2), which elongate body is designed to be mounted to rotate in the spindle passageway (20), the spindle passageway including a portion (23) for receiving the elongate body (30) and designed to allow the elongate body (30) of the stirrer member (3) to pass through it, and a portion (21) for receiving a seal (1), which portion has an inside diameter greater than the inside diameter of the portion (23) for receiving the elongate body (30) and receives an annular seal (1) designed to allow the elongate body of the stirrer member to pass through it. The inside peripheral face of the annular seal (1) is provided with a helical lip (120).
