Abstract
Abstract An eight-sided foldable container having a bottom of the glued-automatic variety is disclosed. The container is constructed from a single sheet of foldable material which comprises eight side panels, a plurality of which are provided with bottom panels which extend angularly downwardly from the side panels via fold lines. These bottom panels are folded inwardly at their respective fold lines toward the center of the formed container such that two pairs are bonded together so as to enable the remaining bottom panels to interlock with and be supported by said bonded bottom panels, thereby forming a container bottom capable of supporting substantial weight, as well as being folded to a relatively flat condition. The blanks used for the construction of the container are also disclosed.
