A container and safety closure therefor includes a hollow container having an externally threaded tubular neck defining a tubular opening into the container. An outer surface area of the container extending outwardly from and adjacent to the neck or portion of the neck or stepped portion thereof or an attached ring has a plurality of recesses extending inwardly. An internal threaded closure adapted to screw on to and off the threaded neck is provided with a web formed integral with a lower edge of the closure and extends outwardly from one side thereof adjacent to the neck. A tab extends upwardly from the web. A pawl formed integrally with either an under surface of the web or in an inwardly facing vertical surface on the web or an outwardly facing surface of the tab is provided to engage the recesses in the container or neck thereof or in the ring when the closure is threadably moved downwardly on the neck. The upstanding tab extends upwardly from distal end of the web. At least one tamper-evident indicating, frangible web connects the upstanding tab to the closure, this web or webs being fracturable by application of a radially, inwardly directed force to the tab which breaks the frangible web or webs and allows disengagement of the pawl from the recesses so that the closure may be removed from the container.
