Abstract
Abstract A method for forming a reinforced artificial fingernail in situ and the article formed thereby, the invention comprising the application of a layer of polymeric material is disclosed, preferably acrylic polymer, to a fingernail through a mask fitted onto the end of a finger, a reinforcing element such as a rigid pin or sheet formed of "glass" fiber or other similar material being then disposed on the layer so formed. A second layer of polymeric material is then applied over the first layer and the reinforcing element disposed thereon, the mask being subsequently removed to allow the reinforced artificial fingernail to be shaped in a conventional manner such as by means of a nail file.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
153 words
A method for forming a reinforced artificial nail on a natural digital nail, comprising the steps of: disposing a mask on the digit on which the natural digital nail is carried to expose upper surface portions of the natural digital nail through an opening in the mask; applying a first continuous layer of hardenable polymeric material to the exposed upper surface portions of the natural digital nail, and to at least portions of adjacent upper surface portions of the mask to extend the apparent length of the artificial nail beyond the length of the natural digital nail; disposing a reinforcing element on at least portions of the upper surface of the first layer of polymeric material; applying a second continuous layer of hardenable polymeric material to the upper surface of the first layer and over the reinforcing element to enclose the reinforcing element between the first and second layers; and, removing the mask.
Claim 2
Independent Claim
153 words
A method for forming a reinforced artificial nail on a natural digital nail, comprising the steps of: disposing a mask on the digit on which the natural digital nail is carried to expose upper surface portions of the natural digital nail through an opening in the mask; applying a first continuous layer of hardenable polymeric material to the exposed upper surface portions of the natural digital nail, and to at least portions of adjacent upper surface portions of the mask to extend the apparent length of the artificial nail beyond the length of the natural digital nail; disposing a reinforcing element on at least portions of the upper surface of the first layer of polymeric material; applying a second continuous layer of hardenable polymeric material to the upper surface of the first layer and over the reinforcing element to enclose the reinforcing element between the first and second layers; and, removing the mask.
Claim 3
Dependent Claim
25 words
The method of claim 1 and further comprising the step of allowing the first and second layers to harden prior to removal of the mask.
Claim 4
Dependent Claim
24 words
The method of claim 1 and further comprising the steps of: allowing the first and second layers to harden; and, shaping the artificial nail.
Claim 5
Dependent Claim
31 words
The method of claim 1 wherein the step of disposing a reinforcing element comprises disposing an elongated pin member on at least portions of the upper surface of the first layer.
Claim 6
Dependent Claim
31 words
The method of claim 4 wherein the pin member is disposed on the first layer with the longitudinal axis of the pin member parallel to the longitudinal axis of the digit.
Claim 7
Dependent Claim
32 words
The method of claim 1 wherein the step of disposing a reinforcing element comprises disposing a sheet of fiber material on at least portions of the upper surfaces of the first layer.
Claim 8
Dependent Claim
83 words
The method of claim 1 wherein the step of disposing a mask comprises: aligning rear and side edge portions of the opening of the mask in substantially surmounting relation to rear and side edges of the natural digital nail; and, disposing a frontal edge portion of the opening of the mask under the distal end of the natural digital nail, the first continuous layer being applied to upper surface portions of the mask adjacent to the distal end of the natural digital nail.
Claim 9
Dependent Claim
17 words
The method of claim 1 wherein the first layer and the second layer comprise different polymeric materials.
Claim 10
Dependent Claim
14 words
The method of claim 1 wherein the first and second layers comprise acrylic polymer.
Claim 11
Dependent Claim
95 words
A reinforced artificial nail for extending and rendering more ornamental a natural digital nail, comprising: a first layer of polymeric material adhered to the upper surface of the natural digital nail, and shaped substantially in the form thereof, at least portions of the first layer extending beyond perimetric portions of the natural nail; a reinforcing element disposed on the first layer; and, a second layer of polymeric material disposed over and adhered to the upper surface of the first layer and the reinforcing element to enclose the reinforcing element between said first and second layers.
Claim 12
Dependent Claim
95 words
A reinforced artificial nail for extending and rendering more ornamental a natural digital nail, comprising: a first layer of polymeric material adhered to the upper surface of the natural digital nail, and shaped substantially in the form thereof, at least portions of the first layer extending beyond perimetric portions of the natural nail; a reinforcing element disposed on the first layer; and, a second layer of polymeric material disposed over and adhered to the upper surface of the first layer and the reinforcing element to enclose the reinforcing element between said first and second layers.
Claim 13
Dependent Claim
13 words
The artificial nail of claim 10 wherein the reinforcing element is a pin.
Claim 14
Dependent Claim
40 words
The artificial nail of claim 11 wherein the pin is disposed with the longitudinal axis thereof substantially parallel to the longitudinal axis of the digit and the pin is arcuately bent to conform to the curvature of the natural nail.
Claim 15
Dependent Claim
16 words
The artificial nail of claim 10 wherein the reinforcing element is a sheet of fiber material.
Claim 16
Dependent Claim
67 words
A reinforced artificial nail for extending and rendering more ornamental a natural digital nail, comprising: a body of polymeric material shaped substantially in the form of a natural digital nail and having a portion thereof adhered to the upper surface of the natural digital nail, at least portions of the body extending beyond perimetric portions of the natural nail; and, a reinforcing element disposed within the body.
Claim 17
Dependent Claim
67 words
A reinforced artificial nail for extending and rendering more ornamental a natural digital nail, comprising: a body of polymeric material shaped substantially in the form of a natural digital nail and having a portion thereof adhered to the upper surface of the natural digital nail, at least portions of the body extending beyond perimetric portions of the natural nail; and, a reinforcing element disposed within the body.
