Abstract
A single piece, molded plastic shelf is configured with spaced channels and ribs having slots to provide upward and downward fluid communication with items stored thereon. A generally flat tray of molded plastic is provided with a flange extending upwardly around its periphery. Rib sections are spaced periodically about the tray, forming generally parallel channels to the rib sections to allow free circulation of air and free drainage of liquids from the underside of stored items. Each rib section extends upwardly a greater extent than the peripheral flange. Slots are provided in each rib section further to allow the free circulation of air or other gases while restricting drainage of liquids.
