  • Patent number: 4520941
    Abstract: A molded plastic crate for transporting and storing five-gallon water bottles having differing external configurations has the general form of an open-ended square box with reinforced internal corner struts nested within each of the four box corners adjacent a centrally apertured box bottom. Exterior midsection portions of the crate side walls adjacent the upstanding box corners are recessed to accommodate hand-truck pickup when the crate is lying on its side. A set of opposed aligned wide handle openings are provided in each pair of opposed crate side walls with one set being located at a different height above the box bottom than the other set. A separate retaining bar which projects into the crate interior near the perimeter of the box open end to restrain a bottle against unintentional slippage from the crate may be retained in place by a steel ring encircling the perimeter of the box open end.
