Abstract
A server lid for a container with an integral tear strip tamper evident feature. 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.
