A ventilated grape box and a one-piece blank for forming it. The blank is formed from corrugated paperboard and is cut and scored to permit it to be folded into a stackable grape box without the need for fasteners. The upper edges of both ends of the box are provided with upstanding stacking tabs which are adapted to fit in complementary recesses in the lower edges of an identical box stacked above it. Each of two upper closure panels is provided with tabs which frictionally engage certain end panels to thereby maintain the upper closure panels closed after the box is filled with grapes. Certain end forming panels are folded to define a triangular column at each inside corner of the box, to thereby increase stacking strength.

A one-peice blank of stiff, bendable and resilient sheet material, such as corrugated paperboard, said blank being generally rectangular and exhibiting mirror symmetry about both its longitudinal and its transverse axis, said blank having a plurality of cut lines and also having a plurality of score lines about which the sheet material can be bent, to thereby define a plurality of panels each having sides and ends, a bottom panel (18), a side panel (20) secured to each side of said bottom panel by a score line, a top closure panel (22) secured to one side of a respective side panel (20) by a score line, a friction tab (24) carried at each end of each of said top closure panels (22), a first end panel (30) secured to each end of each said side panel (20) by a score line (56), a first stacking tab (32) carried at an edge of said first end panel (30), a second end panel (36) secured to each end of said bottom panel (18) by a score line (50), each of said second end panels (36) carrying a pair of stacking tabs (44), a third end panel (60) connected to a respective said second end panel (36) by a spaced pair of spaced apart, parallel score lines (38, 40), a pair of serially connected post forming panels (62, 64) secured to each side of a respective third end panel (60), said post forming panels (62, 64) and said third end panel (60) being of the same width, a fourth end panel (66) secured to a respective one (64) of said post forming panels, said fourth end panel (66) having a portion thereof which is of the same width as the width of said post forming panel (64) to which it is attached, a pair of stacking tab receiving openings (53) intersecting each score line (50) between saind bottom (18) and second end panels (36), the bottom panel (18) portion of said stacking tab receiving openings (53) having a portion (52) spaced from said score line (50) between said bottom (18) and second end panels (36) a distance equal to three thicknesses of said sheet material, said third panel (60) having a pair of spaced apart locking tabs (70, 70), and wherein each fourth end panel (66) carries a locking tab (72).
