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 .
