Abstract: The invention relates to an arrangement for dismantling a container (10) which comprises a circumferential wall (20) and an opening surrounded by said wall and which has a screening cover (14) situated above the opening, and to a dismantling tool for cutting segments (42, 44, 46, 53, 56) out of the circumferential wall. The dismantling takes place in such a way that regions of the circumferential wall which have a hollow cylindrical geometry are successively cut into segments and these segments are then removed. After a segmented region having the hollow cylindrical ring geometry has been removed, an end edge of the remaining circumferential wall is available. The screening cover has a lowering device for successively lowering the screening cover onto a particular available end edge.
