The container includes a receptacle having tapered upright walls that are capped by a lid. The receptacle has an abruptly enlarged upper perimeter joined to a lower perimeter by a horizontal ledge, which resists bulging of the walls under heavy loading. The lid has grooves at stacking support surfaces in which reinforcing members are disposed. The reinforcing members can include winged saddles to disposed in indentations in the lid that are designed to better distribute loads through the receptacle.
