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.
Claims20
A container lid, comprising:
- a flange configured to attach onto a top end of a container;
- a lower portion extending inward and downward from the flange;
- and
- an upper portion comprising a top portion and a peripheral portion between the top portion and the flange, the peripheral portion switchable between (i) a first state where the peripheral portion is deformed upward to raise the top portion from the lower portion, and (ii) a second state where the peripheral portion is deformed downward to lower the top portion onto the lower portion, the peripheral portion formed with one or more vent holes that are blocked by the lower portion in the second state but opened in the first state, the peripheral portion configured to automatically switch from the second state to the first state when pressure of a gas within the container rises above a threshold to release the gas.
(canceled)
A container assembly comprising:
- a container comprising an open top;
- and
- a container lid configured to attach to the open top of the container, the container lid comprising:
- a flange configured to attach onto a top end of the container;
- a lower portion extending inward and downward from the flange;
- and
- an upper portion comprising a top portion and a peripheral portion between the top portion and the flange, the peripheral portion switchable between (i) a first state where the peripheral portion is deformed upward to raise the top portion from the lower portion, and (ii) a second state where the peripheral portion is deformed downward to lower the top portion onto the lower portion, the peripheral portion formed with one or more vent holes that are blocked by the lower portion in the second state but opened in the first state, the peripheral portion configured to automatically switch from the second state to the first state when pressure of a gas within the container rises above a threshold to release the gas.
