  • Patent number: 7100473
    Abstract: A screw lid opener is disclosed which can be converted in an extremely simple manner from one lid radius to another With a screw lid opener having a lever-like handle with a clamping device thereon for holding a screw lid, the lid radius is set by three clamping cheeks for clamping on a screw lid. The clamping jaws are arranged at a distance from a center between the clamping jaws. In accordance with exemplary embodiments, at least one clamping jaw, whose distance from the center can be changed, is provided. This permits the conversion from one lid radius to another. Advantageously all three clamping jaws are embodied to be movable in the same way. With the same spectrum at various radii of lids, this results in a shorter travel for the individual clamping jaw.
