ABSTRACT:
A cardboard insert for reinforcing collapsible packages, such as see-through plastic bags, is formed from a onepiece blank in which a number of panels are separated by score lines. The panels are sized and shaped to define the desired form, generally a right paralleliped, and the mating edges of the insert blank are pre-slit - and alternate tabs bent inward to form interlocking fingers. The interleaved projecting tabs define a locked seam which is, additionally, reinforced by the adjoining inward-bent tabs. The seam is formed by bending the several panels along the score lines to form the finished shape of the insert, and interleaving the projecting tabs of the free edges.
