ABSTRACT:
A novel extended edge tray assembled from a single blank of paper stock is provided, the blank including a major and a minor panel integrally connected along a foldable flange-forming spine. The major panel is dimensionally larger than the minor panel. Other discretely foldable flange-forming members are formed along the edges of the minor panel. To assemble the tray, the flange is formed in the spine and the minor panel is rotated 180.degree. until it overlies the major panel. The minor panel is secured to the major panel and the flanges are formed therein. Means provided for interlocking adjacently abutting flanges and corners defined therebetween are integrally formed with the assembly. None of the cut edges of the blank are exposed in the assembled tray. A suitable cover may be telescoped over the erect flanges for covering the open tray.
