  • Patent number: 5713248
    Abstract: An unscrewing device for threaded plastic plugs applied to bottles has a handle formed by a suitably shaped longitudinal element (11). A cylindrical ring (12) departs from the end of the handle, and is interrupted over a suitable length (T) by a free end in proximity to the end of the element (11) from which it extends. A curved element (13) extends outward from the free end and is directed in an opposite direction, practically forming a trigger. Inside the cylindrical ring (12) can be inserted in succession reduced rings (22, 32) that are also interrupted over suitable lengths (T1-T2) and that present diameters that progressively decrease. The plug to be unscrewed is inserted in the internal holes of the rings (12, 22, 32). The user grips the longitudinal element (11) and pulls on the trigger (13) with the index finger, producing scarfing so that rotating the longitudinal element (11) around the axis of the plug unscrews the plug.
