Abstract
Abstract A safety closure for a vial including a restraining ring rotatably surrounding the vial with its upper face engaging rim of the vial and having a gap in the upper member of the ring for slidably engaging an inwardly projecting lug disposed within a closure member. With the lug disposed through the gap on rotation in relation to the ring, it forms a positive frictional engagement with the lower face of the upper member to form a single unit rotatable about the vial. To gain access to the contents of the vial, it is necessary to rotate the ring in relation to the cap until the lug and gap are in register in order to remove the cap from the restraining ring.
