Abstract (en)
[origin: US4326639A] A screw cap which can be screwed onto the thread of a bottleneck is provided with an outward-projecting collar joined to the cap via shearable links, said shearable links having different flexibility are arranged and formed in such a way that the shearable links of one group can be sheared off only after an angular torsion of the cap relative to the collar which is several times greater than that required for shearing the links of the other group.
