[Problem] To provide containers stronger than conventional containers with respect to a lateral load when stacked. [Solution] The containers according to the present invention are configured so that a corner engaging projection and a corner engaging recess are engaged at the four corners on the bottom face and the top face of a top and a bottom container when stacked, thereby allowing such containers to hold up against the lateral load received when stacked by dispersing the lateral load more widely than conventional containers. Thus, the present invention achieves a higher strength with respect to the lateral load when stacked than conventional containers and prevents incidents where a first sidewall and second sidewall would be separated from each other due to the first sidewall or second sidewall being pushed and bent outwards.
