Abstract
Wall panels for a corrugated paper board container have bulge control lines formed therein to control the bending of the wall panels as the container is loaded with contents, such as liquid containing contents. The bulge control lines are configured to control the bending of the wall panels to mitigate the possibility of undesirable spouting that makes the containers more difficult to store.
