  • Patent number: 5363978
    Abstract: A vent assembly for the seal of a food container including a vent opening in the seal panel at least partially surrounded by an upperwardly opening recess with the vent opening and recess being below the plane of the upper face of the panel. A vent cover pivotally mounts to the seal and, when selectively closed over the vent hole, partially overlies the recess to allow for engagement of fingers with the cover in the recess for upwardly opening of the cover. The closed cover does not project above the plane of the top panel of the seal as to interrupt the planar nature thereof.
