Abstract
A triangular paperboard container for fast foods, particularly pizza slices, is fashioned from two triangular tray halves. The upper tray half is provided with a plurality of manually actuable over center toggle locking tabs which are pushed down and pass between opposed tips of respective notches. The notches are spaced along the upper edges of the bottom tray half side walls. When pushed downwardly, each toggle locking tab engages and distorts opposed points at the entrance to each notch, the opposed points resuming their original position after the tab has passed them, by virtue of the inherent resiliency of paperboard. The locking tabs themselves also distort somewhat when pushing them down. Each notch includes oppositely sloping edges against which opposite sides of a corresponding toggle locking tab engage.
