Abstract
Closure mechanisms and seal integrity indicators for sterilization containers are provided. For example, a closure mechanism comprising at least one handle and at least two arms is provided with a sterilization container lid to apply a more uniform or evenly distributed force to a container gasket. A container body defines an inner lip on which the gasket and lid are received such that the sealing interface is recessed within the container. Further, 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.
