Abstract: A heavy-duty pallet box for bulk goods and palletized loads. The knockdown box may be folded for storage. To erect it, a flat board comprising a pair of complementary, die-cut blanks, or a unitary blank comprising complementary halves, is unfolded. A central side panel and a pair of adjacent, foldable side panels on each blank are separated by score lines for folding. Suitable flaps project from each blank for gluing them together. A lower, generally trapezoidal segment is formed at each blank bottom, below the central panel. The latter segments, one from each of two blanks, are coupled to form the knockdown bottom of the desired foldable container. Smaller trapezoidal flanges project downwardly from each blank at opposite sides of the larger trapezoidal segment. These flanges include suitable glue tabs. When assembled, the flanges form a shelf that braces the container bottom, reinforcing the structure.

Abstract: A rectangular or square shipping package or wrapper for a picture frame, mirror, or the like, having four corner protective forming elements is made from a one-piece, die-cut blank of corrugated board, paperboard or fiberboard with the corner protectors being defined by four, multi-paneled, fold-out flaps capable of capture from the confines of the blank and foldable into a plurality of corner protective pockets, each of the flaps being located in a separate quadrant of the blank.
