Abstract
A tray composed of a unitary, continuous blank has an inner surface and an outer surface. The tray comprises a bottom wall, a plurality of sidewalls extending upwardly from the bottom wall and a plurality of minor flaps. Each of the plurality of minor flaps is connected to one of the sidewalls via a fold line and has a respective outer edge. At least one of the minor flaps is connected to a sidewall via a first cut score. The first cut score extends upwardly from the bottom wall without extending to an outer edge of the minor flap. The at least one minor flap is separated from the sidewall via a knife cut. The knife cut extends from near the outer edge of the minor flap downward toward and near the first cut score. The at least one minor flap has a second cut score formed therein. The second cut score extends from near the separation means. The first and second cut scores are formed from opposing surfaces of the blank so as to form a partial web.
