Abstract: A can opener includes a housing, a driving gear, a reduction transmission device, a cutting wheel, a slide, an idling wheel, a first driven gear, a second driven gear, a torsion spring, a third driven gear, and a cam. The driving gear rotates the cutting wheel and the first driven gear. The first driven gear drives the second driven gear which rotates the third driven gear which rotates the cam which moves the slide which moves the idling wheel, so that the idling wheel is moved toward the cutting wheel to clamp the rim of the lid between the idling wheel and the cutting wheel. The idling wheel and the cutting wheel are moved along the rim of the lid to cut the rim of the lid and to separate the lid from the can to open the can automatically.

Abstract: An easy to operate, extremely quiet, efficient can engagement and opening mechanism is provided for use in an opener for a can, and that provides a pair of missing teeth operating endpoints at opposite ends of its opener cycle, along with an eccentrically operating idler gear and cutter gear urging mechanism that produces a non-jamming foolproof mechanism that can be urged forward to a closed and operating position or reversed to a disengagement and non-operating position.

Abstract: A can opener has first and second operating elements pivotal with respect to one another. The first operating element has a rotatable traction wheel and the second operating element has a cutting assembly. The operating elements pivot such that traction wheel and cutter assembly are moveable between an inoperative position and an operative position. In the inoperative position, the traction wheel and cutter assembly are spaced from one another so that the rim of the can to be opened is locatable between the traction wheel and cutter assembly. In the operative position, the traction wheel and the cutter assembly are in close proximity and engagable with the can to effect opening of the can. The cutter assembly has an axle engaged with the second operating element at a first end and has a thread at a second end. A rotatable circular cutting blade is located on the axle between the first and second ends and is held in place by a nut engaged with the thread. A decorative cover covers the nut.

The can opener has a traction wheel rotatably mounted on the first operating element and a cutter blade rotatably mounted at an inclined angle on the second operating element. At least two abutment surfaces provided on the can opener for engagement with the axially outer edge of the rim of a can. The first abutment surface is operatively forward of the cutter blade and the second abutment surface operatively follows the cutter blade. In use the axially outer edge of the rim can convexly deform proximate the cutter blade. The traction wheel has a radial surface with teeth orientated to engage the radially inner surface of the can rim and an axial surface with teeth orientated to engage the axially outer rim of the can.

Abstract: An ergonomic, electric can opener sits squarely on a kitchen counter and has working features such that the user need not turn the opener to see where to place the can. The housing and working features of the can opener are situated at about a 45 degree angle to the front of the kitchen counter, and a person using the can opener can easily see both an operating lever and a place to insert the can for opening. The can opener is advantageous to persons with arthritic conditions, requiring no orientation in a preferred direction by a user, a minimum of force to operate, and automatic stopping.

Abstract: A dual-handle pump-action can opener that can be operated by either hand and cuts the exterior wall of the seam of a can, rather than the top lip of the can. The dual-handle pump-action can opener includes: (a) a housing having a first handle; (b) a cutting wheel associated with the housing and the first handle and having a cutting edge for severing the exterior wall of the can seam; (c) a traction wheel associated with the housing and the first handle and having a gripping surface for engaging the interior wall of the can seam; and (d) a second handle which is movable towards and away from the first handle. When the second handle is initially moved towards the first handle after the can opener is installed on the seam of the can, it causes the traction wheel to contact the interior wall of the can seam and the cutting wheel to contact the exterior wall of the can seam.

Abstract: A can opener is provided including a housing and an elevator mounted on the housing. Next provided is a blade assembly having a rotating blade. The blade assembly is coupled to the elevator for being moved downwardly upon a can such that the blade engages a lid of the can for removal purposes.

Abstract: An improved outer wall can opener includes a retractable and extendable traction wheel which selectively grips a can to be opened between it and an outer seam wall cutting wheel. The cutting wheel is a ring which is supported by a generally cylindrical stepped bearing which steps outward in increments and also mounts an abutment ring with an outside diameter slightly larger than the outside diameter of the cutting ring. The stepped bearing with the attached cutter ring and abutment ring rotates around a stationary shaft, thus preventing overwear of the cutting ring and allowing wear that does occur to the cutting ring to be uniform and gradual.

Abstract: The present invention is a can opener with a manual turning knob and a magnet. The can opener has a first cutting side, second turning side, an upper handle, and a lower handle. The manual turning knob comprises a wheel with indentations. The top of the wheel may be flat, allowing the user to turn the wheel with his or her palm. The manual turning knob is disposed adjacently to the second turning side on a pivot post which intersects the lower handle. Attached on the opposite end of the pivot post is a driving toothed wheel which rotates upon rotation of the manual turning knob. A cutting edge or disk is disposed adjacently to the first cutting side on an upper rivet, the upper rivet extending out from the first cutting side of the upper handle. A magnet is disposed on or adjacent to the cutting disk such that a completely severed lid of a can will rotate toward the magnet. The magnet and cutting edge are angled downward toward the lid of the can.

Abstract: A can opener has two relatively pivotable body portions, one carrying a rotary cutting wheel and the other a rotary traction wheel having parallel axes, the opener being arranged to receive the rim of a can between the two wheels and to orbit the can as the traction wheel is rotated while the cutting wheel makes a peripheral cut, the traction wheel being shaped to distort the rim during cutting and the cutting wheel having an outwardly angled body portion, adjacent its cutting tip, then angled body portion being adapted to contact the outside of the rim below the cut to exert a force in the opposite direction to the traction wheel.

Abstract: A plier-type can opener has two arms 1, 2 that are pivotally connected to one another. The rotatable parts required for the can opener to cut open a lid of a can and to advance the can are combined into preassembled units that are mountable to the arms. The rotatable parts include a cutting wheel 5, a feed wheel 7, a turning handle 4 and toothed wheels 6, 8. The rotatable parts included in the units are respectively mounted in respective cutouts on the arms 1, 2. The cutouts open toward each other and are provided on an inside edge portion of each arm so that after the units are pressed into respective cutouts, then during use of the can opener when the arms are closed to open a can, the closing of the arms enhances retention of the units in their respective cutouts.

Abstract: A can opener of the type in which the can is opened by cutting through an outer part of the rim joining the lid with the main body of the can. Cam means (51) are arranged to engage outside wall of the can immediately beneath the rim, the engagement underneath the rim moving the cam means and cutter wheel (40) against resilient means (54) to a position such that the cutter wheel makes its cut at a substantially constant predetermined distance on the rim. The drive wheel can have an outer cylindrical surface which is toothed and its lower edge bevelled or chamfered.

Abstract: An improved can opener for removing the tops of cans of both straight sided tin can containers and containers having recessed tops such as commonly found in extruded aluminum cans used in the beverage industry. The improvement modifies the conventional hand held, two handle can opener commonly available of the type in which the handles pivotally separate to allow entrance of the can bead for engagement by lower traction wheel and an upper cutting wheel, the improvement being an extended rest protruding perpendicularly outward and against which the recessed top containers may be positioned and held in that position in order to be engaged by the traction wheel upon the lower end of the bead and the cutter wheel through the top.

Abstract: A can opener (10) has a cutter roll (40) for cutting an outer seam wall (49) of a double end seam (41) securing a can end (43) to a can body (45). A traction roll (20) of the opener (10) is engageable with the end seam (41) and is rotatable to drive the cutter roll (40) about the seam (41). An abutment (52) is provided to engage the end seam (41) to position the center (O.sub.c) of the cutter roll (40) behind that (O.sub.T) of the traction roll (20) in the direction of movement of the opener (10). The two rolls (20,40) have skew axes so that in use the cutter roll (40) cuts into the outer seam wall (49) ahead of a plane (P.sub.1) through the traction roll axis and the cutter roll center (O.sub.c), and so that a generator (51) of the cutter roll's curved surface (48 ) is inclined where the cutter roll (40) contacts the outer seam wall (49) from the cutting edge (50) towards a plane (P.sub.5) containing the top (47).

Abstract: An adapter is provided for the conventional can opener which allows the can opener to be used for removing the top of a common aluminum type beverage can. A circular ring sized to slidably fit the outside of a beverage can is held in position by a support member which includes a mounting flange which can be secured to an outward extending flange of a can opener. A clamp or other suitable fastener may be used for attaching the adapter to the can opener. The support member holds the can positioning ring so that the bottom portion of the can is tilted outward and slightly forward from the can opener cutting mechanism. The rotation of the cutting wheel is reversed from normal so that the forward portion of the can is drawn into the cutting edge to permit the can top to be severed and the remaining edge rolled under. The adapter allows the opened beverage can to be used as a beverage glass, a baking pan, or a container for potted plants.
