A valve () is disclosed which is operable to automatically transition from a closed state to an open state in response to heat. The valve () includes: a cover () having at least one opening () therein; at least one adhesive layer () for sealing a perimeter of the cover () to a wall () of a food cooking package () on which the valve () is positioned; and, a deformable element () that shrinks in response to being exposed to heat, the deformable element () having a perimeter which is sealed by an adhesive when the valve () is in its closed state, wherein shrinking of the deformable element () pulls the perimeter of the deformable element () away from a site where it is sealed by the adhesive, thereby breaking the seal about the perimeter of the deformable element () and transitioning the valve () from its closed state to its open state.

Heat and/or steam activated valve and method therefor

A venting device that may be used directly with a container or via a vent cap for a container, includes a venting mechanism having one or more collapsible dome structures and an absorbent material to prevent leakage of liquid or flowable contents from within the container. The construction relies on a combination of venting domed structures and expandable absorbent material to seal one or more openings in a container and or cap.
