Filed:

Aug 22, 2000

Appl. No.:

09/643465

Inventors:

Sung Yong Chang - Roslyn Heights NY

Assignee:

KMC Exim Corp. - Port Washington NY

International Classification:

A45D 3100

US Classification:

132200, 132 73, 264222, 264DIG 30

Abstract:

An ornamental accessory for a fingernail comprises an overlay having a reusable pressure-sensitive adhesive layer pre-applied to a bottom surface thereof for application and bonding to the wearers natural nail, and a method of making the same. The adhesive formulation is a copolymer of acrylic ester and vinyl acetate formed from an aqueous acrylic copolymer emulsion. The bottom surface of the overlay to which the adhesive is applied is textured to enhance adhesion of the adhesive layer. A method for forming a pre-glued ornamental fingernail accessory includes the steps of forming an overlay having the shape and size of a natural fingernail and applying an aqueous copolymer emulsion, as described above, to a bottom surface of the overlay. The emulsion is allowed to cure whereby a substantial portion of the water in the emulsion is evaporated to form a reusable pressure-sensitive adhesive layer fixed to the overlay. The pressure-sensitive adhesive layer is reactivated by adding an aqueous solution to the dried aqueous copolymer emulsion.

KMC Exim Corp. - Port Washington NY

International Classification:

A45D 2900

US Classification:

132 73, 132 735

Abstract:

The present invention relates to an artificial nail with excellent antibacterial effects. In addition, the present invention concerns a method for manufacturing the antibacterial nail, wherein ABS resin material and an antibacterial agent are mixed together. The mixture is then compressed to make resin pellets, and the pellets are molded into an artificial nail by injection molding.

International Classification:

B21D 3500

US Classification:

294695, 132 73, 156 61

Abstract:

A method for manufacturing a metallic artificial nail for attachment to a natural nail includes the step of heat-stamping a metallic substrate having a heat-activatable layer to a surface of a contoured nail body whereby the metallic substrate is bonded to the nail body. Also provided is a die set for heat-stamping a metallic substrate onto a contoured nail body to form a metallic artificial nail which includes a die including a first contoured surface substantially corresponding to the contour of a bottom surface of the nail body for supporting the nail body in the die set and a punch including a second contoured surface positioned opposite the first contoured surface. The second contoured surface substantially corresponds to the contour of a top surface of the nail body for conforming the metallic substrate to the contour of the top surface of the nail body during heat-stamping.

International Classification:

A45D031/00

US Classification:

132 73

Abstract:

An artificial nail for attachment to a natural nail includes a nail body having a proximal end sized and shaped to be attachable to the top surface of the natural nail and a distal end opposite the proximal end. Extending outwardly from the distal end of the nail body is an application tab which is adapted to be grasped during attachment of the nail body to the natural nail.
