The bulk material container according to the invention comprises a container (3) which is vertically movable in a frame (1), guided in its movement by at least four guides (5) which can slide or roll along vertical struts (4) of which there are accordingly at least four. The vertical struts (4) are connected to one another by metal side plates (2). The container (3) is reinforced by a plurality of transverse roof-shaped struts (6) which connect two walls of the container (3). On its upper edge the container (3) further comprises a roof-shaped strip (7) which is firstly used to reinforce the edge and secondly prevents bulk material remaining on the edge. An outwardly and downwardly inclined roof-shaped strip (8) extends around the periphery of the container (3), is rigidly connected to the latter, is again used as a reinforcement, and prevents bulk material passing into the space between the container (3) and the metal side plate (2). A plurality of roof-shaped webs (9) extend in the lower region of the frame (1), transversely thereto, and are rigidly connected to the metal side plates. The base of the container likewise contains an appropriate plurality of roof-shaped webs (10) alternating with the webs (9) of the frame (1). The webs (9) of the frame close the apertures between the webs (10) of the container (3) when the container is lowered into the frame. If the container (3) is raised on two pairs of vertical plates (12), the bulk material in the container (3) can run out through said apertures. The frame (1) comprises four load take-up devices (13) at which the container is raised and by means of which it can be locked to another container or to a transport device.
