ABSTRACT:
A can opener comprising a housing having a handle. There is a cutting wheel with a cutting edge for severing a can wall, the cutting wheel defining a cutting wheel axis. There is a traction wheel having a gripping surface to engage a can, the traction wheel defining a traction wheel axis. A pair of spindles rotatably mount the traction wheel and the cutting wheel in the housing such that their axes are substantially perpendicular and the wheels are positioned adjacent and spaced apart from each other to define a gap adapted to accept a can to be opened. One of the wheels is movable toward the other to close the gap thereby engaging and locking the can between the cutting wheel and the traction wheel such that the cutting wheel acts to sever the can wall and the traction wheel acts to move the can past the cutting wheel. In order to close the gap, a fixed thrust surface associated with the housing, and a spaced, adjacent movable thrust surface associated with the movable wheel are provided. A pivoting lever is introducible between the thrust surfaces such that the movable thrust surface is moved away from the fixed thrust surface to displace the movable wheel with respect to the other wheel. A transverse handle is associated with one of the wheels to effect rotation thereof.
