Abstract: Embodiments of the present invention include a specimen enclosure apparatus. The specimen enclosure apparatus includes a container having a cavity configured to receive the specimen and an opening extending through a neck of the container to the cavity. An internal flange is positioned intermediate the neck of the container. The specimen enclosure apparatus further includes a closure device configured to be received in the opening. The closure device has a flange seal portion configured to contact the internal flange to form a flange seal proximate the cavity and further has a radial travel limiter integrally formed with the closure device that is configured to contact the container in the opening to limit radial movement of the flange seal portion relative to the internal flange. Containers and closure devices are also provided.
