PURPOSE: An object of the invention is to provide an improved container for storing produce and which will permit gas exchange with the ambient environment to increase the time for which the produce can be stored in a fresh condition. CONSTITUTION: A vented container for produce having a base (12) and a cover (14) which are at least substantially impervious to gas transfer. The base includes a base panel (16) and side walls (18). Preferably two vent apertures (24) are formed through the side wall, and a plug (26) is provided for each vent aperture, to permit the vent apertures (24) to be selectively opened. The plugs (26) may be mounted upon vent toggles (28), such that manual pivoting of the vent toggles (28) will open or close the associated vent aperture (24). 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 (24) closed permits the container to be used as a normal sealed food storage container. The base panel (16) preferably includes an alternating series of hills (44) and troughs (46) to segregate condensate within the container. The troughs (46) may be downwardly concave to further subdivide the condensate within each trough. The hills (44) may include central depressions (48) to act as traps to reduce condensate flow over the hills.
