Abstract: A sterilization indicator for a sterile container includes a shape-memory element in the form of a compression spring, which, when a predetermined temperature is reached or exceeded, subjects an indicating unit to a defined axial compressive force. The indicating unit is biased by a restoring spring in the counter-direction of the shape-memory element by way of a restoring force which is smaller than the defined axial compressive force. A latching mechanism can be actuated by a closing or locking mechanism of the sterile container. Following or during the closing or locking of the sterile container, the latching mechanism retains the indicating unit in a sterile position, once the unit has been moved into the sterile position by the shape-memory element. Upon opening or unlocking of the sterile container below the sterilization temperature, it frees the indicating unit, whereupon the restoring spring moves the indicating unit back into an unsterile position.
