Abstract
A can opener for opening cans of the type having a lid joined to the main body by a rim formed of inner and outer lid surfaces folded onto the upper edge of a can wall. A toothed drive wheel rotatably mounted on a housing engages the inner surface of the rim and forces the outer rim surface against a cutter wheel when a drive shaft is rotated by a turning handle. The turning handle is threaded onto the drive shaft so that rotating the handle both rotates the drive wheel and pulls it tightly against the housing which holds a rotatably mounted cutting wheel. This cuts through the outer lid surface to free the lid from the can. The cutting wheel has an outwardly flaring upper cutting edge and the drive wheel has a curved surface for contacting the inner margin of the rim. The two surfaces coact to force the upper cut surface outwardly and the lower cut surface inwardly. Consequently, as the lid is cut free, it is flared outwardly from the can wall for ease of manual removal and replacement. The cut surfaces are not sharp and there is no contact between the opener and the can contents. Any metal shavings would fall outside the can because the cut is outside the wall of the can.
