Abstract: A storage container includes a bottom wall, a pair of side walls extending up from the bottom wall, and a pair of end walls extending up from the bottom wall, the bottom wall, side walls, and end walls being interconnected and defining a cargo space. A side rim is disposed on top of the side walls and includes a bottom portion extending outwardly from the side wall and an arch extending upward and downward from the bottom portion. The arch defines a convex upper surface and a concave interior arch surface. A middle portion extends upwardly from the arch, an upper portion extends inward from the middle portion, and a lip extending downward from the upper portion and outside of the cargo space. A plurality of spaced apart ribs extend downward from and traverse the concave interior arch surface.
