1. Field of the Invention
The present invention relates to spill containment devices and more particularly pertains to a new spill containment device for containing leakage from an oil tank supplying oil to a heating system.
2. Description of the Prior Art
The use of spill containment devices is known in the prior art. U.S. Pat. No. 5,111,271 describes a device for connecting to and extending around a riser pipe and containing spills that occur when a supply pipe is connected to the riser pipe. Another type of spill containment device is U.S. Pat. No. 5,313,991 for being positioned around loading and unloading connection to catch and retain spillage from the connection during the loading and unloading process. Another type of spill containment device is U.S. Pat. No. 5,313,991 for providing additional containment around access pipe fittings of underground storage tanks.
While these devices fulfill their respective, particular objectives and requirements, the need remains for a device that has certain improved features allowing for containment of an above ground oil tank and containing any leakage from the oil tank to minimize environmental impact and to facilitate reclamation of product leaked from the oil tank.
The present invention meets the needs presented above by generally comprising a container including a bottom wall and a perimeter wall being coupled to and extending upwardly from the bottom wall to define an interior space. An upper edge of the perimeter wall defines an upper open end of the container to permit an oil tank to be placed in the interior space. A lid is hingedly coupled to the upper edge of the perimeter wall. The lid selectively closes the upper open end of the container when the lid is in a closed position over the upper open end. The lid is pivoted away from the upper open end to permit access to the upper open end.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the invention, along with the various features of novelty which characterize the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The invention will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
A reinforcement plate 32 is coupled to an interior surface 34 of the perimeter wall 16. The reinforcement plate 32 reinforces a portion of the rear portion 26 of the perimeter wall 16 to receive a filter 2. The reinforcement plate 32 inhibits the filter 2 from pulling through the perimeter wall 16 when the filter 2 is coupled to the reinforcement plate 32 and the perimeter wall 16.
A lid 36 is hingedly coupled to the upper edge 20 of the perimeter wall 16. The lid 36 selectively closes the upper open end 22 of the container 12 when the lid 36 is in a closed position over the upper open end 22. The lid 36 is pivoted away from the upper open end 22 to permit access to the upper open end 22. The lid 36 comprises a plastic material to resist damage from exposure to environmental elements and exposure to petroleum products. The lid 36 includes a top wall 38 having a front end 40 and back end 42. The back end 42 is hingedly coupled to the rear portion 26 of the perimeter wall 16. The rear portion 26 of the perimeter wall 16 has a thickness greater than the rest of the perimeter wall 16 to support a weight of the lid 36 when the lid 36 is pivoted to allow access to the interior space 18. The front end 40 is positioned adjacent a front portion 44 of the perimeter wall 16 opposite the rear portion 26 when the lid 36 is in the closed position. The top wall 38 has an upper surface 46 being substantially convexly arcuate to inhibit collection of rain and snow on the lid 36 when the lid 36 is in the closed position.
The lid 36 also includes a pair of side walls 48. Each of the side walls 48 is integrally coupled to one of a pair of side edges 50 of the top wall 38. Each of the side walls 48 has a bottom end 52 extending between the front end 40 and the back end 42 of the top wall 38. The bottom end 52 of each of the side walls 48 is positioned adjacent one of the pair of side portions 30 of the perimeter wall 16 when the lid 36 is in the closed position. A lip 54 is coupled to the front end 40 of the top wall 38 and the bottom end 52 of each of the side walls 48. The lip 54 extends outwardly and downwardly from the top wall 38 and the side walls 48 to extend over a portion of the perimeter wall 16 when the lid 36 is in the closed position. A handle 56 is coupled to the top wall 38 adjacent the front end 40. A window 58 is positioned in the top wall 38. The window 58 is positioned adjacent to the front end 40 to permit viewing of status gauges of the oil tank 1 when the lid 36 is in the closed position.
In use, the oil tank 1 is inserted into the interior space 18 of the container 12. The filter 2 is mounted to the reinforcement plate 32 and connected to the oil tank 1. The connection to the heating system is extended through the access aperture 28 and connected to the filter 2. The lid 36 is the pivoted over the upper open end 22 to inhibit rain, dirt and snow from entering the interior space 18 of the container 12. The status gauges of the oil tank 1 can be viewed through the window 58 to determine an amount of oil in the oil tank 1 when the lid 36 is in the closed position. To fill the tank, the lid 36 is opened to allow access to the oil tank 1.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
