PROBLEM TO BE SOLVED: To provide stacking containers like a carrying container of beverage cans which are used in a vertically stacked manner in a plurality of stages, high in stability in a stacked condition, and easy in judging a top and a bottom. SOLUTION: Fitting structures A and B to be fitted to a top surface and a bottom surface of the containers 1 and 2 are formed. The fitting structures A and B are assumed to provide a projecting surface part 3a of a normal diamond shape in plan view on a center portion of the top surface or the bottom surface, a projecting rib 6a is formed from the center of each side of the projecting surface part 3a to a corner part on one side, a recessed part 7a is formed from the center of each side to a corner part on the other side, the fitting structures A and B are point-symmetrical, and horizontally turned by 90 deg. to overlap the projecting rib 6a on the recessed part 7a. Thus, the fitting structures provided on the top surface and the bottom surface of the upper and lower containers can be fitted to each other even when the containers are stacked in the same direction, inversely in the longitudinal and transverse directions, with the top and the bottom of the containers upside down, or in a staggered manner in the longitudinal and transverse directions. |
