Fastening consists of a ring with an inner annular thrust collar (20), fitted with an optional seal (5) against the end of a container neck, and a skirt (21) which fits over the neck and has lugs (22) to grip it. Each of the lugs has one or more deformation zones (221, 222, 223) causing them to bend inwards when an axial pressure is applied to its free end. Fastening consists of a ring with an inner annular thrust collar (20), fitted with an optional seal (5) against the end of a container neck, and a skirt (21) which fits over the neck and has lugs (22) to grip it. Each of the lugs has one or more deformation zones (221, 222, 223) causing them to bend inwards when an axial pressure is applied to its free end. An outer sleeve (30) fitted over the skirt prevents the lugs from bending outwards. An Independent claim is also included for a preparation of the device. |
