ABSTRACT:
A container for hot carry-out food includes a container body and a cover, each having flanges and the flanges defining a pair of seals between which is a condensation collecting chamber and radially outboard of an outermost seal is a second condensation collecting chamber which is continuously vented to atmosphere through radial venting passages or channels. Under elevated pressures, as might occur when hot food is packages in the container, the innermost seal opens permitting steam/gasses to vent into the innermost condensation collection chamber in which the steam might condense as condensate. Under higher internal container pressures, the outboardmost seal may also open and vent gasses from the innermost condensation chamber through/into the outermost condensation collection chamber and continuously from the latter to atmosphere through a plurality of continuously open circumferential spaced radial venting passages or channels.
