OUTLET VALVE FOR A CONTAINER

An outlet valve (20) for a container, such as a bioreactor container, is described. The outlet valve comprises a membrane (22) and is attachable to the wall of the container such that the membrane is arranged to face the interior volume of the container. The outlet valve further includes an actuator operable to move the membrane from a first position in which the membrane lies substantially within the plane of the wall of the container to a second position in which a portion of the membrane is displaced from the plane of the wall of the container such that the membrane is in a frustoconical shape. 本发明描述了一种用于容器例如生物反应器容器的出口阀(20)。该出口阀包括膜(22)并且该出口阀可附接到容器的壁上，使得膜被布置成面向容器的内部容积。出口阀进一步包括致动器，该致动器可操作以将膜从膜基本上位于容器的壁的平面内的第一位置移动到膜的一部分从容器的壁的平面移位使得膜是截头锥体形状的第二位置。
