ABSTRACT:
A tamper-indicating closure for a container includes a cap with removable panels of a top wall of the cap. Each removable panel is connected to a tab on the inside of the cap. The top wall includes inner and outer cams on an inside surface and the tabs underlie the cams. A liner disc is applied inside the cap for sealing against the container. A plurality of spaced-apart ratchet teeth are arranged in one or two circular patterns on the liner disc and sized and located such that the circular pattern of teeth meshes with the two cams. The tabs have a toothed transverse cross-section which allow the tabs to ride over the ratchet teeth in a screwing-on direction to the cap, but the tabs are engaged by the ratchet teeth in a screwing-off direction of rotation of the cap. Since the liner disc and ratchet teeth are stationary with respect to the container, unscrewing of the cap causes the ratchet teeth to separate the panels from the moving cap.
