A container. The container is provided with a base and two pairs of opposing side panels, each side panel being foldably connected to the base. The container further includes connecting members provided on both side edges of each side panel. The two adjacent side panels are operatively connected to each other by means of cooperation between the corresponding connecting members, and the sum of the width of each side panel and the width of the connecting members provided on this side panel is less than the distance between the inner wall surfaces of a pair of adjacent side panels.
