ABSTRACT:
A cap assembly for a threaded neck of a container includes an inner threaded cap which fits closely within an outer cap that is rotatable about the inner cap within defined limits. The outer cap includes a transparent window through which means are displayed to provide a positive indication of a prior usage or tampering. In one embodiment, a drive bar and a series of breakable fins on the outer cap seen through the window are moved into contact with a break and open bar on the inner cap. After the fins are broken, the drive bar engages the break and open bar to permit rotation of the inner cap with the outer cap and removal of the assembly to open the container. Replacement in the opposite direction causes the drive bar to engage a close bar on the inner cap to reseal the container while the broken fins remain visible. A second embodiment has an indicator sleeve instead of fins with a second drive bar to move a SAFE indicia in view of the window during the opening rotation. When the cap is replaced and tightened, a warning symbol moves into view to indicate the prior opening. The original safe position cannot be restored without damaging the cap.
