Abstract
Abstract A transparent, flexible curtain with spaced access slits is provided for installation across the opening of display-type, open front and open top coolers, freezers and the like of the sort used in retail food stores. The curtain is comprised of a rectangular sheet of flexible, transparent material secured at one end to the top or rear edge of the cooler cabinet and extending across the cabinet opening. The curtain is formed with a plurality of spaced parallel slits, all extending in the same direction and all originating and terminating within the margins of the sheet. The curtain retains cold air within the refrigerator and allows the food products to be clearly visible to the customer. Goods are removed by the customer reaching through any slit near the product selected. The forward or lower edge of the curtain is weighted in sections to keep the curtain taut across the opening and to allow it to be folded back for loading food into the cooler.
