Abstract
A stackable parallelepipedic container comprises an annular peripheral box-shaped profiled top edge portion (9, 10), which is provided at the top portions of the side walls of the container body and has a top portion for supporting a container cover (13). The container is stable, shockproof structure and can be handled in a simple manner and used to store solid and liquid materials. The container cover (13) consists of a flanged blank having lug-like extensions (22), which protrude from the side edges (21) of the cover and are disposed at right angles about the side edges (21) of the cover. Profiled metal strips (26) are welded to the extensions (22) and constitute an annular peripheral profiled edge portion (40) of the cover. The profiled edge portion (40) of the cover is supported by a peripheral sealing ring (12) on the top portion of the profiled top edge portion of the container body. The profiled edge portion (40) of the cover and the profiled top edge portion of the container body are formed with aligned bores and are clamped against each other by clamp screws (17) extending through the bores. The container cover (13) has a central portion provided with an opening which is closed by another cover (43).
