| 摘要 |
The invention concerns a closure comprising a base part (3) having an outer annular projection (27) and peripheral notches (30) and a part forming a cap designed to be mounted on the base part, comprising a tamperproof strip having an inner annular projection and peripheral notches. The co-operation between the projections and the notches lock the two parts. When it is mounted, the radial clearance between the peripheral zone of the base part where are located its notches and the peripheral zone of the tamperproof strip where are located its notches is reduced, providing slight rotation of the cap relative to the base part, until one notch of the strip is opposite an interval between two neighbouring notches of the base part. |
