摘要

A locking device is disclosed for locking a cap on a container with a flange including a lid housing a bushing provided with lower inner notches supported under the flange and outer notches engaging with a groove in the lid to secure the bushing to the lid, the lid including a severable frangible zone, the bushing being formed by a ring extended by lugs intended to surround the cap and provided with at least one deformable and severable bridge provided opposite the lugs and capable of being elastically deformed radially to allow the forced insertion of the flange into the bushing and of being broken to allow the removal of the bushing relative to the flange followed by the removal of the cap from the container.

主权项

1. A device for locking a stopper on a container having a flange, the locking device comprising:
a cap with at least one internal groove, the cap being shaped so as to cover the stopper and surround the flange and thereby render the stopper inaccessible; and a collar capable of being housed inside the cap and having lower internal lugs that provide support beneath the flange in order to cause the collar to interlock with the container and the collar having external lugs that engage with the groove in order to cause the collar to interlock with the cap, the cap further including at least one frangible zone capable of rupturing so as to permit the opening of the cap and the withdrawal thereof relative to the flange, the collar being formed from a band that is extended by tenons that surround the stopper, the collar being provided with at least one deformable and breakable bridge that is arranged opposite the tenons and able on the one hand to elastically deform radially in order to permit the forced insertion of the flange into the collar and on the other hand to be broken in order to permit the withdrawal of the collar relative to the flange and then the withdrawal of the stopper from the container.
