Abstract (en)
[origin: EP0729894A2] A closure 10 comprises a cap 11 having a skirt 13 depending therefrom, skirt 13 having an internal screw thread 14 or equivalent for engagement with a complementary formation on a container (not shown), and the closure 10 further comprising a tamper-evident ring 30 attached to skirt 13 by frangible bridges 20 and at least a portion of tamper-evident ring 30 having an undercut profile 32 for engagement behind a prolection on the neck of a container during removal of closure 10. This ensures effective separation of tamper-evident ring 30 from closure 10, with retention of tamper-evident ring on the container neck. Preferably, bridges 20 extend in a non-axial direction from the bottom rim 16 of skirt 13 to the radially innermost extremity of tamper-evident ring 30. Bridges 20 may be narrower in section adjacent skirt 13. Optionally, skirt 13 and tamper-evident ring 30 have complementary formations (46, 36; See Figure 4) which interengage when closure 10 is screwed onto a container. The undercut profile 32 is preferably provided on a series of radially inwardly projecting nibs 31 formed on the inner surface of the ring 30, the nibs being of ratchet configuration for engagement with dogs formed on a container neck. <IMAGE>
