Exhibiting favorable attributes of both a regular slotted container ("RSC") and an automatic bottom container, a sheet material container is quickly and easily erectable from a knocked-down-flat ("KDF") container precursor. The precursor collapses to a uniform two-layer KDF condition which permits stable, even stacking of multiple precursors for bulk shipping and storage of the same. The precursor is formed from a blank including a plurality of wall panels hingedly attached to each other along fold lines to form a closed loop of wall panels, and a plurality of end flap panels hingedly attached along fold lines to ends of the respective wall panels. A pair of adjacent end flap panels lie in face-to-face relation with each other in the KDF condition. One of the adjacent pairs of panels has a diagonal fold line defining a corner attachment region that attaches to the other end flap panel. As the closed loop of wall panels is erected from the KDF condition to form a rectangular tubular shape, the diagonal fold line and associated attachment of end flap panels cause the end flap panels to pivot inwardly to automatically form an end closure (e.g., bottom) surface of the container.
