20. A package comprising
a container including a bowl formed to include an interior product-storage region and a brim coupled to an upper portion of the bowl and arranged to border a top opening into the interior product-storage region, the brim including an endless upwardly facing top surface including an endless inner perimeter region bordering and surrounding the top opening and providing an endless temporary sheet-bonding zone thereon and an outer perimeter region surrounding the endless inner perimeter region and providing a ring-support zone thereon,
a membrane sheet coupled to the brim of the container, and
a hermetic steam-venting system that provides a hermetic seal between the membrane sheet and the container until a user separates the membrane sheet from the container or a user applies a predetermined amount of heat to the interior product-storage region to cause sufficient pressure to form in the interior product-storage region so that a pressurized discharge outlet is formed between the membrane sheet and the brim of the container in the endless temporary sheet-bonding zone during heating,
wherein the steam-venting system includes an inner sealed annular ring located in spaced-apart relation to the interior product-storage region and a series of spaced-apart sealed tethers appended to the inner sealed annular ring and arranged to extend outwardly away from the interior product-storage region.
