COLLAPSIBLE CONTAINER Russian patent published in 2015 - IPC B65D85/46 

FIELD: packaging industry.

SUBSTANCE: container comprises side barriers (1), each of which is an H-beam consisting of two T-beams (11, 12) interconnected by welding, each of which is part of the I-beam cut along the longitudinal axis. The cutting line is made in the form of identical isosceles trapezoids. The T-beams are interconnected by the small bases of the trapezoids (15, 16), the elements in the form of squares. Along the vertical line of symmetry of the connecting elements on both sides of the wall of the beam the reinforcement ribs (21, 22) are welded with thrust. The ends of the beams are welded to flanges. The side barriers at the ends are rigidly and releasably interconnected by load frames (2) of rigidly and releasably interconnected upper and lower parts, each of which comprises support racks connected at right angle by the cross elements. The lower part of the frame with the support racks (7, 8) is rigidly connected to the flanges of the side barriers. The height of these racks coincides with the height of the side barriers.

EFFECT: increase in rigidity of the structure, the possibility of transportation of long loads in a wide range of longitudinal dimensions, simplification of loading and unloading.
