  • Publication number: 20240002114
    Abstract: Embodiments relate to a container lid with vent holes that are blocked for storage but automatically unblocked when a container attached to the container lid is heated. The heating of the container lid causes the pressure to build in the container, which pushes up an upper portion of the container lid. When the upper portion of the container lid is pushed up, the vent holes are unblocked and enable air or vapor to escape through the vent holes. In this way, the container lid may seal the container during storage but enables automatic venting during the heating of the container to prevent buildup of excessive pressure within the container.
