There is disclosed a half-slotted container body and lid, each made from a blank of corrugated paperboard. The lid blank has an additional score to provide a fold-line around the perimeter of the side and end panels at approximately one-half of the depth. This score line defines inner and outer panels of the lid\s perimeter side and end walls. Where this fold-line intersects each of the panel score lines defining the ends of the side and end panels, there are two diagonal scores which radiate from that point in opposite directions extending to the free edge of the inner panels. When the lid is set up, the top flaps are folded inwardly and secured to form a top of the lid, and the inner panels are folded inwardly hinged at the four corners by the diagonal scores. The inner panels are pushed in at the interior four corners of the lid locking the inner panels along the outer panels to provide a two-ply perimeter wall of the lid. The resulting inward bulge of the inner panels of the lid create a secure lock of the lid on the body and provide support for the sides of the body against outwardly bulging under load. The continuous two-ply construction of the sides of the lid provide channeling space between adjoining containers in a stacked pallet load to enhance uniform air flow and cooling of produce, such as bananas and fruits, packed in the containers.

A blank for forming a container lid comprising alternating side and end flaps hinged along one of their sides at a first longitudinal fold-line, said flaps being separated from each other from said fold-line to one longitudinal edge of the blank, a second longitudinal fold line parallel with the first, lateral fold-lines extending from the first longitudinal fold-line to the other longitudinal edge of the blank, said lateral fold-lines defining alternating side and end panels and a tab, said tab being disposed at the end of the blank providing a manufactures joint for fastening the blank into a closed perimeter of the lid, said second longitudinal fold-line forming side-by-side inner and outer panels disposed lengthwise along one side of the blank, two diagonal fold lines provided by scores in the blank extending from the intersection of each lateral fold-line and the second longitudinal fold line to the adjacent other longitudinal edge of the blank, said two diagonal fold-lines having an included angle of 90 degrees and each extending 45 degrees from said second longitudinal fold line, said diagonal fold lines, together with the lateral fold-line adapted to provide a gusset-style corner for the lid upon folding the inner panels inwardly about said second longitudinal fold-line.
