VACUUM LID

摘要

A vacuum lid for sealing a container. The vacuum lid is adapted to seal a container. The lid has a knob, either a twist knob or a push-pull knob, which, when twisted or pushed, forces air inside the container out through evacuation ports. This creates a vacuum inside the container, which aids in maintaining freshness of consumable foods or other substances that degrade over time in the presence of air.
