Abstract (en)

[origin: US4771904A] A tamperproof closure for a container having a threaded neck comprises a cap having an outside skirt threaded on the inside to be engaged on the neck of the container. The skirt is extended by a tamperproof band which is connected to the skirt by bridges of material that can be cut. The neck of the container is provided with a plurality of circumferentially oriented radial catches. The tamperproof band has a plurality of inside radial lugs having a profile complementary to the neck lugs, the catches and lugs being configured to permit passage of the latter over the former in the direction of screwing, and to oppose passage in the opposite direction. Below the threaded part of the container neck is provided a flange of cross section exhibiting a profile converging toward the bottom of the container. A face of each inside radial lug of the tamperproof band is beveled toward the direction of the cap top. When the flange of the neck of the container is placed axially on the neck, a traction stress is exerted on the tamperproof band in the direction of the bottom of the container.
