ABSTRACT:
A rectilinear rigid and closable poultry or red meat container assembled by travel of a male forming mandrel pushing a single blank of paperboard past a series of wings and rollers. The container blank is complete with container base, end walls, side walls, bridge tabs and closable lid. The closable lid sections are interconnected with the end walls by a bridge tab between the lid section flanges and the end wall flanges. This bridge tab permits the use of simple machinery heretofore only suitable for assembly of open top containers which therefore are not lid-integral. Additionally, integral with the single blank are side wall flanges and end wall flanges which provide near complete triple thickness side walls upon assembly, imparting increased stacking strength sufficient to permit use of economically advantageous relatively light weight paperboard.
