A safety closure of the type having a unitary construction with a closed top from which an interiorly threaded skirt depends and a container having an exteriorly threaded neck on which the closure is mounted in sealing relationship. The safety closure has at least one locking member formed integrally therewith which is movable under the action of actuating apparatus between a non-locking position and a locking position in which the locking members engage appropriate corresponding locking elements provided on the neck of the container. The actuating apparatus is constituted by the top of the closure which has a dish-like configuration formed such that the application of a sufficient finger pressure on the top will result in the movement of the locking members from the locking to the non-locking position. The construction and mode of operation of the safety closure renders it especially suited to the incorporation of a device for providing a visual indication of the initial unlocking actuation of the closure thereby indicating a possible unauthorized tampering with the contents of the container should the device indicate such unlocking actuation prior to the sale of the product to the consumer.
