The invention relates to a double valve (1) intended to engage with a lid (9) of an anti-spill cup for children, having a first valve (2) enabling the entry of air inside of the cup, and a second valve (3) enabling the flow of a liquid outward from within the cup. According to the invention, the first valve (2) has at the upper portion thereof a duck beak-shaped shutter (23) enabling air to flow inside said cup, the second valve (3) has an at least partially concave upper outer surface forming a shutter (32) enabling the flow of said liquid outside of said cup. Said first and second valves (2, 3) are directed in opposite directions (SENS1, SENS2), the direction of a valve (2, 3) being defined from the base (21, 35) thereof toward the shutter (23, 32) thereof. |
