Abstract
A container designed for assembly without separable fasteners to comprise a leakproof receptacle or tray for use by meat packers and others. The container is formed from a single blank of corrugated fibreboard having a water-repellent surface. It comprises sides (23, 24) and ends (21, 22) rising from a bottom (10) orthogonally, and interconnected by webbed corners (25, 28). The ends are provided with flaps (30, 40) including lock tabs (31, 32, 41, 42) with tongues (33, 34, 43, 44) which cooperate with the flaps to hold the corners against the outsides of the ends, and the material is crushed, at the lower corners (110) of the container and at the points of action (120) of the tongues, to provide flexibility and prevent damage to the material at sharp folds.
