ABSTRACT:
In a multi-chamber container (1), in which is accomodated at least one chamber partition wall (4) movable through the two chambers and having at least one orifice (8) which makes a connection between the two adjacent chambers (2, 3) and interacts with a shutoff member and which can be opened and closed via a tappet (10) actuable from outside, the chamber partition wall (4) sealed off on the inside of the container being movable through the container (1), according to the invention the orifice (8) in the chamber partition wall (4) is equipped to receive a thread of a valve spindle (23) which can be screwed in by means of the tappet and which terminates at a stop (24) interacting with one side (26) of the chamber partition wall (4) and at a valve plate (32) formed by a ring (32) of the rod and ensuring sealing on the opposite side (35) of the chamber partition wall (4), the valve plate (24) and the stop (32) being layable onto their seats (27, 23) as a result of an alternating rotation of the rod (10), and the valve plate (32) closing the connection between the two chambers (2, 3), which, when the valve plates (24, 32) are lifted off, is opened and which is formed by longitudinal grooves (28, 31) of the valve spindle (23), these reaching as far as the stop (24) located at the free end of the spindle (23) and terminating at a distance from the valve plate (32) formed by the ring (32).
