Abstract

See full text

A microwave cooking container includes a bag portion having an open end for access to an interior of the bag and a closure mechanism for sealing the open end having elongated interfitting elements extending adjacent the open end of the bag. The container also includes a valve assembly providing controlled discharge of pressurized fluid from the bag interior when a positive pressure equal to or exceeding a predetermined pressure is created within the bag interior. The valve assembly includes a vent member and a flow limiter. The vent member is located at the open end of the bag adjacent an end of the closure mechanism such that the first end of the internal passage is in fluid communication with the bag interior. The internal passage provides an exit path for discharge of a pressurized fluid from the interior of the bag. The flow limiter may include an end portion of a closure clamp adapted to receive the vent member.
