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 hand-held can opener is provided with a grip handle, a grip block pivotally mounted to the forward end of the grip handle, a scissor handle pivotally mounted to the grip block and having a one way roller clutch connection with a unidirectionally driven feed wheel. The grip block is provided with a latch. Squeezing of the scissor handle toward the grip handle with pivot the grip block to position the feed wheel relative to the cutter for penetration of the can lid and lock the grip block into this position. Subsequent release and squeezing of the scissor handle will drive the feed wheel undirectionally for advancing the can lid past the cutter.

Abstract: A tool for opening of a can or the like has a first portion and a second portion extending transversely to each other. The second portion has a pointed tip and a cutting edge, whereas the first portion has a cutout with an outlet which is open at the second portion. The second portion partially overlaps and laterally limits the outlet of the cutout of the first portion. When the tool is placed onto a bead of a can, one wall section of the cutout is supported on the bead, and a wall of the can is firmly clamped between another wall of the cutout of the first portion and an overlapping section of the second portion. Thereby, a very clean cut is obtained and a small force is needed for cutting through a cover of the can. Two such second portions may be provided, one of which second portion is suitable for cutting by a right-handed person, whereas the other of said second portions is suitable for cutting by a left-handed person.

Abstract: A can opener has a first flat member provided with two open slots spaced from one another in direction of elongation, and a second member having two oppositely facing cutting edges so that the can opener can be used by both left-handed persons and right-handed persons. The members are separate and connected with one another by connecting unit which allows their movement between unfolded operative position and folded inoperative position. The connecting unit is arranged between the cutting edges. A unit preventing an unintentional movement of the members from the inoperative position is also provided.
