Abstract (en)
A membrane for bottom-ventilation of a baby bottle (1) containing suckable liquid, having an air inlet cut (22), characterized in that at least one of the facing edges (23,23a) of the cut (22) is formed with surface roughness.The invention solves the problem of progressive healing of the cut formed on the membrane element of a ventilation device to equalize the pressure inside a baby bottle during suction, thereby avoiding the progressive increase of the force required to cause separation of the edges of the cut and the passage of ventilation air.
