  • Patent number: 6679271
    Abstract: A nail care apparatus comprises a motor housing having two ends: a handle end and a rotating housing end. A replaceable tip is inserted into the rotating housing so that it rotates along with the housing end. A disposable manicuring cylinder that is comprised of a soft polyurethane rubber in the shape of a hollow cylinder is then secured onto the replaceable tip, allowing it to rotate along with the replaceable tip. A power supply is connected to the housing at the handle end and provides power to an electric motor inside the motor housing such that the operation of the motor causes rotational movement of the rotating housing. The manicuring cylinders would be manufactured by slicing long tubes polyurethane rubber into desired lengths. The outer surface of the manicuring cylinder would be granular due to either a surface coating of sand powder mixed with adhesive or a sandpaper laminate, thus allowing uniform and even buffing and polishing without the risk of unnecessary keratin erosion.
