  • Patent number: 6367651
    Abstract: A vented container for produce having a base and a cover which are at least substantially impervious to gas transfer. The base includes a base panel and side walls. Preferably two vent apertures are formed through the side wall, and a plug is provided for each vent aperture, to permit the vent apertures to be selectively opened. The plugs may be mounted upon vent toggles, such that manual pivoting of the vent toggles will open or close the associated vent aperture. The selective opening of the vent apertures permits gas exchange between the interior of the container and the ambient atmosphere, providing improve storage for produce. Maintaining the vent apertures closed permits the container to be used as a normal sealed food storage container. The base panel preferably includes an alternating series of hills and troughs to segregate condensate within the container. The troughs may be downward concave to further subdivide the condensate within each trough.
