ABSTRACT:
An improved pilfer-proof screw-on bottle cap having a ring section attached thereto with frangible bridges, wherein the ring section has at least four inwardly extending molded-in-place hooks. The hooks are circumferentially positioned at the edge of the ring section distal to the cap and engage a radially extending bead on the bottle, thereby preventing upward movement of the ring section together with removal of the bottle cap. The frangible bridges break under continued removal forces, thereby causing the ring section to become detached as an indication of tampering. The frangible bridges are located relative to the radially extending bead of the bottle at a position proximate to and no higher than the lower edge of the bead. Tampering removal of the cap and ring section, as a unit, by deliberate disengagement between the hooks and the bead, caused by squeezing of the ring to swivel the hooks away from the bead, causes the frangible bridges to move to breakage, as a lever against the lower edge of the bead as a fulcrum.
