Abstract
Abstract A preformed artificial nail is provided having a convex upper surface and a concave undersurface which, together, define a forwardly extending free end and a recessed trailing end which terminates in an arcuate wall formed intermediate the length of the nail. This wall includes a forwardly extending groove positioned above the undersuface of the free end of the nail. A mass of viscous adhesive material is positioned atop the natural nail and the artificial nail is forced downwardly so that the adhesive fills the space between the natural nail and the undersurface of the artificial nail and a small excess thereof is exuded forwardly into the groove.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
82 words
A preformed artificial nail comprising a concavo-convex molded piece having a convex upper surface formed and finished to resemble a natural nail; and a concave undersurface extending from the forward end to the rearward end which, with said upper surface, defines a forwardly extending free end and a recessed trailing end; said recessed trailing end terminating in an arcuate wall formed intermediate the length of said nail, said wall including a forwardly extending groove positioned above the undersurface of said free end.
Claim 2
Dependent Claim
82 words
A preformed artificial nail comprising a concavo-convex molded piece having a convex upper surface formed and finished to resemble a natural nail; and a concave undersurface extending from the forward end to the rearward end which, with said upper surface, defines a forwardly extending free end and a recessed trailing end; said recessed trailing end terminating in an arcuate wall formed intermediate the length of said nail, said wall including a forwardly extending groove positioned above the undersurface of said free end.
Claim 3
Dependent Claim
21 words
A preformed artificial nail as recited in claim 1 in which said nail is constituted by an elongated molded plastic piece.
Claim 4
Dependent Claim
22 words
A preformed artificial nail as recited in claim 2 in which said nail has the shape and appearance of a lady''s nail.
Claim 5
Dependent Claim

A preformed artificial nail as recited in claim 2 in which said nail is a molded piece of methyl methacrylate.
Claim 6
Dependent Claim
29 words
A preformed artificial nail as recited in claim 1 in which said arcuate wall extends forwardly of the nail to about the midpoint along the length of the nail.
Claim 7
Dependent Claim
82 words
A method of applying a preformed artifical nail comprising positioning the recessed trailing end of the artificial nail of claim 1 over a shortened natural nail with the said arcuate wall immediately forward of the natural nail, said natural nail having a mass of viscous adhesive overlying the same, forcing the artificial nail downwardly until said adhesive completely fills the space between the natural nail and the undersurface of the artificial nail, and a small excess thereof exudes forwardly into said groove.
Claim 8
Dependent Claim
29 words
A method as recited in claim 6 in which said artificial nail is a molded piece of methyl methacrylate polymer and said adhesive as a methyl methacrylate monomer-polymer syrup.
