Abstract
Abstract A transparent, flexible curtain with spaced access points is provided for installation over the opening of a display type open refrigerator of the sort used in retail food markets. The curtain is comprised of a plurality of elongated, flexible, transparent panels secured at one end to the top or rear edge of the refrigerator cabinet and extending in overlapped relation across the cabinet opening. The edges of the panel are tubular and a colored sleeve may be added to make access points between adjacent panels more readily visible. 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reaching in between adjacent panels which separate easily and return to a closed position when the customer's hand is withdrawn.
