The present invention is a self-closing cap (1, 50) which comprises a base (2, 60) having one or more holes (4, 65). A lid (10, 61) is movably mounted about the base (2, 60), said lid (10, 61) having one or more holes (11, 66), and capable of occupying a first open position and a second closed position. In the first open position, the holes (4, 65) of the base (2, 60) align with the holes (11, 66) of the lid (10, 61). In the second closed position, the holes (4, 65) of the base (2, 60) do not align with the holes (11, 66) of the lid (10, 61). A spring means (30, 90) is provided between the base (2, 60) and the lid (10, 61) in order to automatically place the lid (10, 61) in the closed position. Further, the underside of the lid (10, 61) is provided with one or more protrusions (20, 80) which seal the holes (4, 65) of the base (2, 60) when the lid (10, 61) is in the closed position.
