A server lid for a container with an integral tear strip tamper evident feature is presented. A tear strip for the tamper evident feature is molded as an adjunct to a base member which forms the closure. The tear strip is joined to the base by at least one frangible web, and hinges about the frangible web to overlie front edges of one or more flaps formed in the server lid. Ultrasonic welds connect the overlying tear strip to the flaps or adjacent the flaps for providing a tamper evident feature. The shape of the server lid provides stackability in that the base rim of the container will fit over the upper portion of the lid, including frangible webs to allow interfitting of one container bottom with the container closure of the next, to allow the containers to be stacked on a shelf without substantial danger of slipping or tipping.
