Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
34 words
Synthetic human nail structure according to claim 1 in which said preformed overlay structure is tapered at its normal inward edge portion to a degree permitting during-application solubilization of the carrier throughout said portion.
Claim 2
Dependent Claim
29 words
Synthetic human nail structure according to claim 1 in which said carrier component is organic solvent soluble and at least one distributed component is insoluble in said carrier solvent.
Claim 3
Dependent Claim
26 words
Synthetic human nail structure according to claim 3 in which said first component is the major component by weight, is resinous and film forming from solution.
Claim 4
Dependent Claim
16 words
Synthetic human nail structure according to claim 4 in which said distributed component is an albuminoid.
Claim 5
Dependent Claim
25 words
Synthetic human nail structure according to claim 5 in which said albuminoid material has an average particle size between about 20 and 400 U.S. mesh.
Claim 6
Dependent Claim
52 words
Synthetic human nail structure according to claim 6 in which said preformed overlay structure is tapered at its normally inward edge portion to a degree permitting obtaining of solution of said first component throughout said portion on nail application whereby the terminus of said nail structure adheres indistinguishably to the human nail.
