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.

L'invention concerne capuchon (1, 50) à fermeture automatique, comprenant une base (2, 60) pourvue d'un ou plusieurs trous (4, 65). Un couvercle (10, 61) est monté amovible autour de ladite base (2, 60), ce couvercle (10, 61) possédant un ou plusieurs trous (11, 66), et pouvant occuper une première position ouverte et une seconde position fermée. En position ouverte, les trous (4, 65) de la base (2, 60) s'alignent avec les trous (11, 66) du couvercle (10, 61). En position fermée, les trous (4, 65) de la base (2, 60) ne s'alignent pas avec les trous (11, 66) du couvercle (10, 61). Un dispositif à ressort (30, 90) est disposé entre la base (2, 60) et le couvercle (10, 61) afin de placer automatiquement ledit couvercle (10, 61) en position fermée. En outre, le dessous du couvercle (10, 61) présente plusieurs saillies (20, 80) qui ferment hermétiquement les trous (4, 65) de la base (2, 60) lorsque le couvercle (10, 61) se trouve en position fermée.
