Vegetable trays

Abstract

The invention concerns corner posts for use with card blanks to form stacking trays, especially suited to transporting garden produce. Corner posts of the invention are elongated elements of substantially right triangular cross-sectional shape having a widest face and two narrower faces, said widest face being formed with two longitudinally extending slots, said slots each having two parallel sides and a base and opening onto said widest face, said sides of one of said slots extending in planes perpendicular to said sides of the other of said slots, and each of said slots having an abutment surface extending in a plane at right angles to said sides and said base and constituting an end to said respective slot, each slot further including an undercut adjacent its said opening to provide a shoulder facing said base of said slot, said slot having a width substantially twice that of said opening of said slot at points between said shoulder and said base. Corner posts of the invention may be formed with end portions adapted to locate two like posts in axial alignment, so that the trays may be stacked up.
