Produce boxes and bags for shipping produce, e.g., bananas, utilize ventilation structures that allow for ventilation therethrough. A method of assembling produce boxes provides for cutouts that serve as ventilation structures in the boxes. When the produce boxes are stacked such as on a shipping pallet, the ventilation structures allow for ventilation of through the stacked boxes. Produce may be packed in a bag, which is closed with a rip cord and inserted into a produce box. The rip cord may be accessed when the box is in a stack such as on a shipping pallet, such that the rip cord may be pulled thereby opening the bag, without removing the box from the stack.

A tray formed of a single piece blank and which has reinforced corners to enable superior stacking capabilities and capacities is presented. The tray includes a base and four panels extending therefrom. Each panel has a major component extending from the base and a minor component extending from opposing sides of the major component. The minor components of the side panels consist of a tab and a freestanding portion. Only the tab is adhesively engaged to an interior surface of an immediately adjacent major component of and adjacent panel. The minor components of front and back panels being adhesively engaged to the major component of the side panels. The reinforced corners having a triangular shape defined by the major component and one minor component of the front panel or back panel and a hypotenuse consisting of one freestanding portion.

A tray made from cardboard sheet material comprising a rectangular bottom and a ring of side walls, i.e., two first opposing side walls, referred to as first walls, at least one of the first walls being connected on either side by first fold lines to end flaps referred to as first flaps, which may or may not themselves be connected respectively at the top part of same to a second flap by a second fold line, and two second opposing side walls, referred to as second walls. The second walls each comprise a rectangular central panel of which the length is less than the length of the bottom, the panel being connected, at each of the lateral ends of same, by a third fold line to a reinforcing member forming a pillar folded and glued to the central panel, and/or to the first flap of the adjacent first wall, i.e., a first reinforcing element located entirely separated from the adjacent first wall, and a second reinforcing element.

A blank of foldable sheet material is provided. The blank includes a bottom panel, a first bottom side panel and a second opposing bottom side panel extending from opposing side edges of the bottom panel, and a front panel extending from a front edge of the bottom panel. The front panel includes opposing side edges. The blank also includes a first and a second diagonal panel extending from a front edge of the first and second bottom side panels, respectively, and a third and a fourth diagonal panel extending from each side edge of the front panel. The third and fourth diagonal panels have a length greater than a length of the first and second diagonal panels. The blank includes a first and a second corner panel, wherein the first corner panel is hingedly connected to the first and third diagonal panels and the second corner panel is hingedly connected to the second and fourth diagonal panels.

A multi-scored corrugated corner element including at least some of a portion of material; a first score mark that provides a line or portion along which the corrugated corner element may be manipulated; a second score mark formed at a spaced apart location from the first score mark that provides a line or portion along which the corrugated corner element may be manipulated; a first corner element leg extending from the first score mark to the second score mark and having one or more alternating ridges and grooves; a second corner element leg extending from the first score mark to the second corner element end and having one or more alternating ridges and grooves; and a third corner element leg extending from the second score mark to the first corner element end and having one or more alternating ridges and grooves.

A packing box has a bottom panel, end panels raised from first edges of the bottom panel, side panels arranged adjacently to the end panels, edge panels connected to side edges of the end panels via outer panel fold lines, fold-back panels arranged on inner side surfaces of the edge panels, inner panels arranged on inner side surfaces of the end panels, and reinforcing panels continuously formed with the fold-back panels via first fold lines and the inner panels via second fold lines. The reinforcing panel 16 is formed in an inwardly projecting manner between the fold-back panel and the inner panel. Any of the first and second fold lines positioned on a side closer to the outer panel fold line than a projecting top portion is arranged away from the outer panel fold line by a distance.

The invention relates to a folding box for packaging, storing or protecting goods, having an outer shell, wherein the outer shell has at least three side walls, an upper side and a bottom side, wherein uprights are at least partially arranged at the corner edges of the side walls and wherein the side walls have connecting elements at the bottom side and/or at the upper side for connecting to the uprights, wherein the connecting elements are adapted to compensate positional tolerances and/or shape tolerances of the uprights.

A blank of foldable sheet material is provided. The blank includes a bottom panel, a first bottom side panel and a second opposing bottom side panel extending from opposing side edges of the bottom panel, and a front panel extending from a front edge of the bottom panel. The front panel includes opposing side edges. The blank also includes a first and a second diagonal panel extending from a front edge of the first and second bottom side panels, respectively, and a third and a fourth diagonal panel extending from each side edge of the front panel. The third and fourth diagonal panels have a length greater than a length of the first and second diagonal panels. The blank includes a first and a second corner panel, wherein the first corner panel is hingedly connected to the first and third diagonal panels and the second corner panel is hingedly connected to the second and fourth diagonal panels.
