Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates generally to a manicure treatment apparatus, and more particularly to a fingernail polishing apparatus which comprises in combination a plurality of polishing sheets having specific filing or polishing functions which depend upon the purpose of treating a fingernail, such as rough shaping to final gloss polishing. The sheets may be employed in a stepwise or random way, depending upon the motive of the user. 
     2. Description of the Prior Art 
     Various fingernail filing or polishing devices of the type enclosed herein for use in manicure treatment are known. As it is commonly known, nail scissors or nippers are available specifically for cutting or trimming fingernails. Some include a roughly notched surface on a part of at least one blade member thereof however this provides only a single function of shaping a fingernail roughly, and it is therefore not intended to make the nail smooth and glossy. Another device is in the form of different powdered abrasives which are separately contained in a bag or box. They may serve multiple functions, but have a disadvantage in that they are very difficult to carry it. A further known device has the three-layer form which consists of a base sheet, an intermediate elastic material and a tape-like abrasive media attached by adhesive material. This has a problem in that it is unhandy.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The invention will further be illustrated by the way of example only with reference to the accompanying drawings. In FIG. 1, a first sheet, generally shown by A, has the function of shaping a fingernail roughly and includes a base sheet 1 of a substantially elliptical shape in plane made of elastic material such as, example, foamed styrol and a coating of abrasive or filing media 2 applied to, for example, one face of the base sheet 1. The abrasive media 2 is composed of a mixture of a hard fine particle substance of relatively coarse grain size, a synthetic resin adhesive and a coloring material such as black. The mixture has the form of powder, and is applied to the surface of the base material 1 by means a coating method to form an abrasive layer shown by 2. In an alternative form, the abrasive media 2 may have the form of a tape cut to the shape of the base sheet 1 and applied thereto. A second sheet, generally shown by B, has the function of polishing the fingernail to a medium degree. As particularly shown in FIG. 3, the sheet B includes a base sheet 3 made of elastic material such as foamed styrol and a coating of polishing media 4 applied to one face of the base sheet 3. The polishing media 4 is composed of a mixture of a hard fine particle substances of smaller grain size than the sheet A, a synthetic resin adhesive and a coloring material for example orange. The mixture in the form of powder is applied to the face of the base sheet 3 by a coating method to form a layer of abrasive media 4. In FIG. 5, a third sheet generally shown by C services the functon of making the fingernail smooth and glossy, and includes a base sheet 5 of elastic material such as foamed styrol and a coating of gloss-making media 6 applied to one face of the base sheet 5. The gloss-making media comprises a mixture composed of a hard fine particle substances of the smallest grain size, a synthetic resin adhesive and a coloring material for example pink. As in the two earlier sheets A and B, the mixture has the form of powder, which is applied to the face of the base sheet 5 by a coating method to form a layer of abrasive media 6. The sheets B and C have the similar shape to the sheet A. In the above embodiment, a coating of the abrasive media of various grain sizes is applied to one face of the base sheet, but may be applied to both faces. This may apply to a varied form which will be described later. The sheets A, B, and C forming a set thereof are held in position in a transparent bag, box or the like. In the drawing, reference numeral 8 denotes a slip placed in the bag for illustrating the mode for use. 
     In the above embodiment, a set of three sheets A, B and C of distinct colors such as black, orange and pink according to the different functions of the sheets have been described, but two more sheets of different colors such as green and yellow may be added, and may serve different functions from the earlier sheets A, B and C. In this varied form, the two additional sheets may have a coating of abrasive media which contains a hard fine particle substance of different grain size from those described earlier. In more detail, one (green color) may polish the nail more finely than the sheet B, and the other (yellow color) may polish the nail more finely than the green color sheet. Thus, a set of five sheets may be available and provide a wider choice of the various functions ranging from the initial rough shaping through intermediate polishing steps to final smooth and glossy finishing. In a further varied form of the earlier embodiments, the sheet C may have a coating of leather or cloth attached by adhesive, which can better polish the nail as the finish treatment. In FIG. 7, a varied form of the first sheet A is shown; it has a substantially elliptical shape and is provided with a recessed portion on both sides. This makes it easy for the sheet to be held by fingers and to be manipulated for the fingernail treatment. The other sheets B, C, etc. may have the similar shape. It should be understood that the materials used for the base sheet and abrasive media are not limited to the embodiments described above, respectively. 
     All the sheets according to the present invention have a base sheet of elastic material such as formed styrol cut to appropriate shape and thickness which makes the sheet fit or agree with the fingernails. Because of their snug and uniform contact with the curved edges of the fingernails, the sheets permit a nail polishing treatment with great easiness and accuracy, resulting finally in a smoothly polished nail. Since the coating of abrasive media applied to the base sheets comprises a mixture composed of powdered abrasive substances of varying grain sizes, and can thus be effected with easiness, a less costly manufacture can be achieved on an automatic and mass production basis. A further advantage of the invention is the provision of distinguishing means by color according to the function of the sheets. This eliminates the need of trying any one of the sheets to make sure that it fits the specific needs of the user such as rough shaping, medium polishing and finish polishing. Accordingly, a proper choice can be made without loss of time and error. A still further advantage is the combination of the multi-functions which can be selected according to the step of the treatment. This permits an extremely delicate treatment or care of the fingernails depending upon the condition of the fingernails. As noted from the above, the invention may form a part of the manicure treatment, and offers a tool therefor. 
     Although the invention has been illustrated by showing the several preferred embodiments thereof, it should be understood that various changes and modifications may be made without departing from the spirit and scope of the invention.
