ABSTRACT:
A box-shaped container of plastics material, particularly a storage and transport container includes a bottom with a flat upper side and a bottom side which is stabilized by stiffening ribs. Flat webs extending in a plane parallel to the plane of the bottom extend along the rim of the bottom. The flat webs form in the manner of a frame a center field of the bottom. The stiffening ribs in the center field intersect each other in the manner of a grid. The flat webs form support surfaces of the container and rest spaced apart from the plane of the bottom on stiffening ribs arranged transversely of the rim of the bottom. Pocket-shaped free spaces are formed between the bottom side of the container bottom, the upper sides of the flat webs and the transversely extending stiffening ribs, wherein the free spaces are completely open to the side of the rim of the bottom. The stiffening ribs which support the flat webs are not connected to the longitudinally and transversely extending stiffening ribs of the center field of the bottom of the container.
