ABSTRACT:
A structure for use in assembly of a non-square center special slotted container is constructed from a single piece, five panel blank having a full end panel, two side panels, and two partial end panels, each having associated flaps, which is folded to produce overlapping of the partial end panels. The end flaps extending from the partial end panels, and the correspondingly disposed flaps extending from the full end panel each are of a length substantially equal to one-half the length of the front and rear side panels. The full and partial end flaps are of equal length on each side of the blank so that contact of the outer edges of the folded blank by platens or other means in the squaring station of a folder-gluer machine properly aligns the blank and consistently produces properly squared and sealed folded blanks.
