CPC B65D 41/3447 (2013.01) [B65D 55/16 (2013.01); B65D 2401/20 (2020.05); B65D 2401/30 (2020.05); B65D 2401/35 (2020.05)] | 17 Claims |
1. A closure in combination with a container having a container neck, the closure comprising a cap, and a retaining ring for retaining the closure on the container neck, a tether is provided between the cap and the retaining ring, one end of the tether is fixedly connected to the cap and the other end is fixedly connected to the retaining ring, the tether is connected to the cap by a root and extends from the root in a clockwise, cap screwing-on direction, the ring is rotatable but exerts a compression force on the container neck whereas the cap is not as impeded in its rotation on the container neck, when the cap is unscrewed and removed for the first time and then re-screwed onto the neck the ring is retarded as it rotates together with the cap and thereby rotates less than the cap causing the tether to buckle and bulge outwards along its length above the retaining ring, thereby providing evidence of tampering.
