Gusseted Tray Corners for Stronger Non-Nesting Stacks

The patent applies local quality by concentrating reinforcement at the corner regions where stacking stress is most critical. The gusseted corners with extended flaps and reinforced edges provide localized structural enhancement without requiring the entire tray to be made from thicker or more abundant material, thus resolving the contradiction between stacking strength and material quantity.

The patent effectively uses composite material construction by combining corrugated board with additional reinforcing elements such as edge flaps, corner gussets, and potential adhesive bonding layers. This composite approach allows the tray to achieve enhanced stacking strength while maintaining efficient overall material usage, as the reinforcement is applied only where structurally necessary.

The patent applies preliminary anti-action by designing corner gussets and extended flaps that proactively prevent nesting before it occurs. The reinforced corners with extended flaps creating interlocking structures counteract the natural tendency of trays to nest, ensuring stable stacking from the outset and maintaining stacking reliability while enabling efficient storage.

The patent utilizes curved or angled corner designs rather than sharp corners to prevent nesting. The gusseted corners with extended flaps create a geometric configuration that resists nesting forces, using curvature and angular geometry to maintain stacking stability and prevent the trays from sliding into each other during storage.

The patent applies segmentation by dividing the corner reinforcement into distinct functional components: corner gussets, extended flaps, and potential edge reinforcements. This segmentation allows each element to be optimized independently for its specific function while maintaining overall structural integrity, managing complexity through modular design rather than a monolithic reinforcement structure.

The patent resolves the complexity-strength contradiction by applying reinforcement only locally at the corners rather than uniformly across the entire tray. The corner gussets and extended flaps provide the necessary structural enhancement at critical points while leaving the rest of the tray design simple and straightforward, thus managing overall device complexity while achieving the required stacking strength.
