Abstract

This is a kind of lateral wall of container, including the substrate base, and the cover. The substrate base is made of multi-blocks of substrate base cell through welding. The mentioned substrate base cell is thin plate with cross-section in wave form. The inner lateral side of the wave crest which faces the inner side of the box is leveled up, with the interconnected parts of the adjacent substrate base cells as the wave bottom. Two wave bottoms, after the two-butt welding, form a concave wave which is depressed to the lateral side of the box; the width of the concave waves on the cover and substrate base suit their shape. And the cover is linked to the concave waves. After the connection and installation, the inner side of the cover parallels with that of the wave crest, enabling the inner side of the box in the direction of the mentioned lateral wall to be in continuous evenness. This utility model effectively prevent the whole substrate base form deforming because of the setting of the cover in the concave waves of the substrate base which is concaved to the lateral side of the box. The cover is fixed with the brink of concaved waves. At the same time, the continuous evenness of the inner side of the lateral wall, scratch and block of goods during the in-and-out process can be avoided which is usually seen in the use of traditional wave-type lateral wall.
