  • Patent number: 5366107
    Abstract: A rectangular container possessing four substantially vertical walls and a horizontal floor molded in one piece of plastic along with a matching waterproof lid molded in another separate piece of plastic is disclosed. At least two of the four vertical walls possess shielded vents comprising apertures through a wall possessing either screening or louvers or both across the entire aperture and rigidly attached to the wall. The uppermost edge of the four walls possesses a preformed U-shaped resilient edge and the lid possesses a preformed U-shaped resilient perimeter. The full engagement of the lid perimeter with the box uppermost edge results in a removable closure of the box interior which is water resistant proof. In one embodiment, the uppermost edge of the front wall is of a constant height which is less than the constant height of the rear wall and the two side walls possess a height inclined from the front elevation to the rear elevation. The slope of the cover sheds precipitation.
