ABSTRACT:
An intake/outtake arrangement of a container for a material may communicate with a tube, a transfer container or the like. In order to control intake or outtake of the material container, the intake/outtake arrangement is movable relative to wall means of the container between an open position and a closed position whereby an intake/outtake opening is opened and closed. A sealing body is located between the material container and the intake/outtake arrangement, and is elastically deformable. The sealing body has an inner cavity to be connected to a source of fluid. When in communication with the source of fluid, the sealing body expands in outward direction while being supported by a rigid inner wall.
