  • Can opener
    Patent number: 4648183
    Abstract: A can opener for removing the top of an aluminum can having an upper rim encompassed by a peripheral crimp in the top, the can opener comprising a container having a cushioned can cavity for receiving an aluminum can, and a cover mounting a rotatable abrasive disk for engagement with the can top, the container and cover being threadably connected so that the disk can be positioned for proper engagement with the can top. Rotation of the disk abrades the aluminum of the can until enough of the peripheral crimp in the can top is removed to permit the top to be separated from the can.
