  • Patent number: 7017587
    Abstract: Unless the nail exposure window of the finger protection sheath is strictly adjusted, the enamel-coated nail portion only is not brought into contact with the spongy member, and the enamel is not reliably and selectively wiped off without hurting the skin. Further, the finger protection sheath does not easily turn unless a large moment of turn is given thereto. The lower rotary shaft of the finger protector sheath of nearly a hollow cylindrical shape is deflected from the finger axis or the center line of the cone in a manner that they meet at ?, enabling the outer diameter portion of the enamel-coated nail surface to be turned like a fan maintaining a radius R(=r+?r) larger than the radius r of the prior art as viewed on a plan view to increase the moment of turn. The nail exposure portion is provided with an automatic cover to thereby also contrive an installation-type device for removing enamel from a multiplicity of nails and a device for removing enamel from the pedicured nails.

  • Patent number: 5613506
    Abstract: A device for removing a manicure coating from a nail at a fingertip is formed of a container, a soft material impregnated with a manicure removing solution and disposed in the container, a closure removably attached to the upper portion of the container for opening and closing the container, an inner closure rotatably attached to the upper portion of the container and having an opening and a cover for closing the opening, and a sheath attached to the inner closure and extending downwardly therefrom to be situated inside the container. The sheath has a side portion, an inner space at least partly surrounded by the side portion and communicating with the opening, and an open portion formed at the side portion. When the fingertip is inserted into the sheath through the opening, the nail can be located in the open portion. In this position, when the finger is turned together with the inner closure, the manicure coating can be removed from the nail by the manicure removing solution contained in the soft material.
