Abstract
Disclosed is a carton which is especially adapted for heating food products such as pizza, in microwave ovens. The bottom surface of the carton is cut to provide a plurality of tabs, which when bent from the carton, provide legs which space the bottom of the carton from a shelf in the oven, thereby allowing moisture vapor generated during heating to escape. According to a preferred embodiment, a moisture barrier film is releasably adhered to the bottom surface of the carton and a plurality of tabs so that, upon removal of the film prior to heating, the tabs are bent into their operable support position and the vent holes are opened.
