ABSTRACT:
A tamper-proof ring for securing a closure over the open end of a container. The closure and container has a projection engageable by the ring which comprises an annular member which before application to a container-closure assembly has a generally cylindrical section of a diameter slightly greater than the greatest transverse dimension of the container. The closure projection and a radially inwardly directed flange at one end of the cylindrical section define a plurality of circumferentially spaced, generally axial score lines extending from the edge of the cylindrical section opposite the one end and terminates at the juncture of the flange and cylindrical section.
