ABSTRACT:
A paperboard tray is disclosed that includes pairs of tuck flaps formed between the side and end panels of the tray. The tuck flaps are folded under the ends of the tray and are rigidly locked in position to give the tray great rigidity and leakproof corners. Tuck flap tabs on the tuck flaps are retained in tab holes in an end flap portion of the tray, and the end flap portion folds over and around the folded tuck flaps to doubly secure them in position.
