Abstract
Abstract A tray for the packaging and shipping of fruits and vegetables, such as strawberries. The tray is formed from a generally rectangular blank which may be hand assembled in the field. The interlocking of the various components of the tray assure a rigid construction. The tray includes central supports in the form of separators or partitions, which central supports have upper edges coplanar with the top surfaces of the ends of the trays so as to support the central portion of the next upper tray. The ends of tray are constructed to provide relatively wide upstanding supports which have extending upwardly therefrom locking flaps engageable within openings in the bottom of a next upper tray. The tray also has a double bottom for added strength.
