ABSTRACT:
Disclosed is a carton which is especially adapted for heating food products in microwave ovens. The bottom surface of the carton is cut to define a plurality of spaced apertures, each of which is closed by removable means. A strip of film is secured to the bottom surface of the carton and the removable means so that, upon removal of the film prior to heating, the means are removed with the film to provide vent holes which allow moisture vapor generated during heating to escape. In a preferred embodiment, the carton has two separable compartments joined by a common top and two common side walls with an intermittent cut line extending across the top and down the common side walls to permit separation of the two compartments. The compartments have individual bottom panels, each of which is cut to provide a plurality of removable tabs held within spaced apertures by spaced nicks.
