ABSTRACT:
An improved can opener includes a disk-like cutter having an inwardly furled rim at a lower edge thereof and pivotally connected to a press lever at a slightly slanting angle, the press lever being pivotally connected via a pivot pin to a handle having a serrated disk rotatable by a rotary knob. When the press lever and the handle are pulled away from each other about the pivot pin, the distance between the serrated disk and the cutter is increased so that a top side of the can can be placed therebetween. By pressing the press lever, the cutter will displace towards the serrated disk, with a part of its cutting blade piercing into an outer peripheral portion of the top side of the can. When the rotary knob is turned, the serrated disk is caused to displace along an inner peripheral portion of the can and the cutter is caused to rotatably cut along the outer peripheral portion of the top side of the can. As the cutter is disposed at a slightly slanting angle, the cutting blade may press against the freshly cut edge of the top side of the can and cause it to curl inwardly, thus preventing the cut edge from hurting people.
