ABSTRACT:
A display tray formed from corrugated or solid fiber paper is useful for packaging, shipping, displaying and transportation of various goods. The tray includes a planar bottom which has a central and two extreme sections formed by a pair of parallel score lines. Opposing ends and sides are joined to the bottom and each side includes a pair of vertical and angular score lines which intersect proximate the bottom score lines for folding purposes. The tray can be easily changed from an open to either a partially or fully closed tray by manually bending along the sides at the described score lines to rotate the end assemblies.
