Abstract: A simple hand held label degrading device and method employs a molded polymer ring (collar) having a plurality of molded hardened pointed teeth on the internal circumference projecting radially inward for degrading the label of a prescription bottle or the like inserted therein. A longitudinal slot in the collar allows it to be fitted over a bottle such that simple hand squeezing of the collar compresses the collar around the bottle and engages the pointed teeth against the label. Simple hand twisting of the collar around the bottle in a clockwise or counterclockwise rotation cuts through the plastic composite or paper label and shreds the label rendering sensitive information illegible thus protecting personal health information. The bottles can then be thrown away or recycled without fear of medical identity theft.
