ABSTRACT:
An end unit of the type including an outer ring and a separately formed cover each having annular channels which interlock to secure the cover in place on the ring and form a seal between the cover and the ring. The interlock is improved selectively by interlocking beads on radially outer walls of the interlocking channels or by a socket in the radially outer wall of the ring channel and a radially inwardly projecting bead on the radially inner wall of the cover channel, the bead projecting into the socket. The interlocks permit greater tolerances in the manufacture of the end unit, particularly the interlocking channels. This also provides for greater tolerances in the application of the cover after the associated container has been filled.
