The invention discloses a light-weight container, and belongs to the technical field of containers. The light-weight container comprises a front end fixing structure, connecting flanges, rotation-prevention pins, air cylinders, binding bands, fixing clamped blocks, a rear end operation box, load transmitting blocks, connecting bolts, M24 nuts, gaskets, container angle elements, vertical columns, cross beams, vertical plates, rib plates, square tube fixing plates, a door, a rear end vertical plate, a framework and M20 nuts. After external threads at two ends of each air cylinder (4) are connected with the connecting flanges (2), the external threads are installed on the vertical plate (16) of the front end fixing structure and a rear end vertical plate (20) of a rear end operation box (7) by 6 M24*80 connecting bolts (10), the M24 nuts (11) and I-shaped gaskets 12; after being installed, the external threads are fixed between the air cylinders (4) and the connecting flanges (2) by the rotation-prevention pins; the external threads of the air cylinders (4) and internal threads of the connecting flanges (2) are all M160*3; the lengths of the connecting threads are 70mm; the air cylinders are arranged in two layers, and three air cylinders are arranged in each layer. The light-weight container has the advantages that not only can the need of increasing the gas transportation amount be met, but also the requirements on each kind of inert force in the transportation process can be met when the container is put on a base plate.
