ABSTRACT:
A container or hopper with a flexible weigh container as an inner member, in which the weigh container is supported through at least one weigh cell on a frame. In order to weigh-in a material to be proportioned, a throttling device is provided at the bottom end of the weigh container. To avoid complicated distributing arrangements and assure precise dosing, the flexible weigh container extends further downwardly like a hose through the throttling device and its bottom is attached to a movable spout which in turn is displaceable in such a manner that the flexible, hose-like extension of the weigh container is carried along with it so as to selectively discharge through different outlets of the container or hopper.
