Abstract
A half-size sheet metal steam table tray and a lid that may be joined by a sealed double seam to the tray to form a container for packing or canning, processing, storing, shipping, distributing, heating, displaying and serving processed food products in any desired manner, and particularly for use at a steam table. The tray and lid container is desirable for institutional use to replace 105 fluid ounce capacity No. 10 cans for processed foods or frozen food containers. The tray serves as a cooking vessel suitable for heating the food product packed therein after removal of the lid and before serving. The tray becomes a serving container replacing stainless steel serving pans commonly used in volume feeding establishments.
