Microwave cooking device with improved venting configuration

A microwave cooking device includes a container for holding a food product, a seal for sealing the container to enclose a substantially fixed volume therein, and a venting configuration. The venting configuration includes a steam guide defining a central vent and a pair of steam horns associated with and positioned on either side of the steam guide. The steam guide and associated steam horns weaken a portion of the seal at a predetermined location and are each in fluid communication with the volume enclosed within the container to allow movement of steam from the container into the steam guide and steam horns, such that, steam and pressure are preferentially directed towards the steam guide, causing pressure to be concentrated at the weakened portion of the seal and resulting in the seal being broken at a predetermined location.
