Abstract: An improved stacking wire is provided for use in carrying and supporting stacked produce containers of the type formed from corrugated paperboard or the like to include a pair of double-layer end walls each defining a vertically open slot for receiving a stacking wire. The improved stacking wire is bent to an inverted generally U-shaped configuration and includes a plurality of spacers disposed at different vertical positions therein for maintaining the end wall layers of a plurality of stacked containers in a predetermined spacing relative to each other and in vertical alignment with the end wall layers of other containers in the stack thereby increasing the vertical stacking strength and lateral stability of the stacked containers to prevent damage to the produce during handling, storage, or shipment.

Abstract: A container for produce and the like is formed by a pair of endwalls and a wrapper. The wrapper is divided by score lines into a floor panel, a pair of sidewalls, a pair of cover flaps and a pair of joiner strips by which the flaps are connected to the sidewalls. The joiner strips permit the flaps to be shifted laterally as well as pivotally. Each flap has a tab at each end thereof that is received, when the flap is closed, in a recess between two lugs on one of the endwalls. The tabs can shift laterally as permitted by undercut portions of the recesses, and must be so shifted and then bowed before they can be withdrawn from the recesses so that the flaps can be opened pivotally.

Abstract: A blank is folded to form a box by pressing it into a jig. End and side panels of the blank, along with supplemental panels at the corners, are lifted relative to a floor panel by folding surfaces of the jig. The side panels are lifted first and supplemental end panels are thus positioned inside the end panels. The blank may also include supplemental side panels that are folded outwardly and backwardly by corner guides of the jig.

Abstract: Boxes for produce and the like formed by corrugated paperboard containers having end walls defining vertical slots that are aligned when the containers are stacked. Column-forming members are inserted in the slots and interlocked vertically. The containers are supported primarily by the inserts so that the combined weight of containers above is not borne solely by the end walls.

Abstract: A lug box having cored-out plastic end walls and a wrapper, preferably of corrugated paperboard, that is nailed to the end walls. The wrapper is formed by a single piece including bottom and side panels as well as foldably attached lid flaps that provide a top for the box. Each end wall has parallel ribs extending along its bottom and side edges that receive the nails. Reinforcing ribs in the center sections of the end walls lend added rigidity and strength.

Abstract: A lug box composed of two end walls of generally rectangular conformation, composed of plastic material, and a wrapper extending between and overlapping vertical side edges and bottom of the end walls. The end walls are cored-out for lightness, but also to provide multiple ribbed structures through which nails are driven from the outside to enhance the degree of securement of the wrapper to the end walls.
