  • Patent number: 6011223
    Abstract: The invention relates to a container with a flexible internal part (6), particularly suitable for weighing bulk material, comprising a closure mechanism within the exit area of the internal part (6) as well as at least two partial exits (18, 19) to be charged, located at the internal part (6) for further processing said bulk material. By means of said locking mechanism, it is practicable to press at least one partial area of the flexible internal part (6) laterally from outside against a sword (14) which is located inside within the exit area of the internal part. This way, said sword (14) separates the partial exits (18, 19) from each other, whereby in each case, one of the partial exits (18, 19) is closable.
