Abstract
A container such as a sump having a bottom, at least one wall extending upwardly from the bottom, and a flange connected to the at least one wall and projecting therefrom. The flange preferably has apertures extending partially into the interior portion of the flange from its exterior surface. The flange provides structural rigidity to the container and prevents irregularities from being formed in the walls during manufacture. Preferably, the container is a sump having four lower walls, four upper walls integrally connected to the lower walls by the flange, and four entrance walls integrally connected to the upper walls and defining a mouth for receiving fluids. The flange preferably has an upper surface having upper apertures and a lower surface having lower apertures that are axially aligned with the upper apertures. Pins may utilized during manufacture of the sump by rotational molding to form apertures within the flange and aid in preventing irregularities from being formed.
