  • Patent number: 5052185
    Abstract: An ice box rack designed to keep the stored food and other items dry, while slowing the melting of the ice. The preferred embodiment of the present invention teaches an ice box rack sized and configured to fit the container of a variety of currently sold ice chests, the rack including as a novel and unique feature a planar lower surface to facilitate the uniform application of compressive pressure on the ice. It has been found that this uniform pressure acts to pack the ice, particularly crushed or chipped ice, causing it to melt less quickly, thereby prolonging the cooling process. The present invention may be configured in a variety of different ways, and may be constructed of a number of different materials, including extruded or molded plastics, wood, aluminum, or the like, all with satisfactory results. Further, the rack design of the present invention may be configured to support a variety of differently configured items, such as unpackaged or packaged foods, can beverages, bulk items, etc.
