A first sloping side wall has an edge integrally formed with a first edge of the top wall and extends downwardly and outwardly at an angle from the top wall. A second sloping side wall has an edge integrally formed with a second edge of the top wall and extends downwardly and outwardly at an angle from the top wall and in a direction perpendicular to the direction of the first side wall.
