Abstract
Seal integrity indicators for sterilization containers are provided. For example, a seal indicator may indicate whether the container is sufficiently sealed to prevent an ingress of contaminants into the container. If the container is sufficiently sealed, the seal indicator is visible, but if not, the seal indicator is not visible. Thus, the seal indicator undergoes a change in state when the sterilization container transitions from unsealed to sealed, or vice versa, such that a user may ascertain whether the container is properly sealed to maintain the container's sterility. An exemplary seal indicator includes an invertible projection formed with the container gasket that is not visible from outside the container until inverted, due to force applied by the lid, to extend through an opening in the container body. Closure mechanisms for sterilization containers also are provided.
