Description
- The present application Ser. No. relates to the application entitled SLUMPED GLASS SPILL PROOF SHELF FOR AN APPLIANCE AND METHOD OF MANUFACTURING A SHELF, attorney docket no. 237978, filed ______.
- The present invention relates generally to shelf assemblies for appliances such as refrigerators and, more particularly, to spill proof refrigerator shelves which do not require a traditional plastic frame while still maintaining a satisfactory structural integrity and spill proof functionality of the products.
- A refrigerator typically includes a number of shelves for the storage of food and beverage containers of a variety of shapes and sizes. As the containers are retrieved, returned and rearranged on the shelves, occasional leaks and spilling of food and liquid may occur. Extensive cleanup efforts are required since the spill will commonly flow down through the compartment, from shelf to shelf. Therefore, it is desirable to provide containment implements for the refrigerator to limit the area of such a spill.
- Traditionally, a spill proof shelf of a refrigerator requires a plastic frame, a glass pane supported by the frame, and one or more metal support brackets which engage the frame and also mate with the cant tracks of the refrigerator. The cost for molding the plastic frame, including the cost for manufacturing a mold for the frame and the cost for assembling the frame with the glass pane and the support brackets, is high. Furthermore, the plastic frame impedes the lighting of the refrigerator. Accordingly, it is desirable to provide a refrigerator shelf, which does not require the frame while still maintaining the structural integrity and the spill proof functionality of the shelf.
