ABSTRACT:
An electric powered can opener has a housing, a feed gear that is motor connected and rotatably mounted to drive and rotate a can by holding it by its rim. An operating lever is pivoted above the gear on the housing and carries a cutter mechanism to remove the can lid. To this conventional arrangement an improvement is added in the cutter mechanism of a non-round cutter wheel connected to and movable by the lever and having a lobed or flat portion within the periphery and oriented so that the cutter wheel is substantially stationary as it is pulled into the can lid such that the meeting edge of the periphery at the flat and round periphery provides a power pierce whereupon the cutter wheel then rotates for a clean severing of the can lid. The cutter is preferably a dish-shaped cutter with a hollow ground flat or lobe portion. The lever is preferably spring biased for rotation toward the can at all times and has a slidable switch actuator that is linkage-connected to the lever for manual operation.
