摘要：A prying device, most uful as a plastic cork lifter, compris an elongated member (10) having a handle ction (12) at one end and a prying ction (14) at the other end. The prying ction compris a fork with parated dual tines (16/18) having narrowed inner edges which fit into the groove between the cork (20) and bottle (22), below the head of the cork above the neckband of the bottle. A wire hoop (24) extends out from the prying ction. The wire hoop is looped around the top of the bottle, just below the cork. The hoop is springably retracted toward the prying ction for storage and for aiding in positioning the dual tines in the groove between the bottle and the cork. The hoop is vertically pivotable at the prying ction and is bent by about 90 degrees to form an upright "V" (34) at approximately midway out from the prying ction. The bend forms a fulcrum point which rests against the side of the bottle at a location slightly down from the cork so that the handle can be rotated down about the fulcrum point, causing the fork to rotate up and lift the cork by multiplied lever force.
