Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
152 words
A decorated, thermoformed article comprising a laminate of a thermoplastic polymer sheet material and a thermoplastic polymer film bonded thereto by heat and pressure, said film having at least one decorative pattern element of an ink composition on the surface thereof adjacent said sheet material and substantially nonadherent to said sheet material, said pattern element having a multiplicity of discrete discontinuities therein each surrounded by said ink composition and spaced about substantially the entire surface thereof and through which said sheet material and film are in direct surface contact and substantially permanently bonded together by heat and pressure, the smallest dimension of each of said discontinuities being about one thirty-second to one-fourth inch, the total void area defined by said discontinuities being about 4.0 to 50.0 percent of the total area of said pattern element, said thermoformed article having at least one wall portion extending at an angle to other portions thereof.
Claim 2
Dependent Claim
152 words
A decorated, thermoformed article comprising a laminate of a thermoplastic polymer sheet material and a thermoplastic polymer film bonded thereto by heat and pressure, said film having at least one decorative pattern element of an ink composition on the surface thereof adjacent said sheet material and substantially nonadherent to said sheet material, said pattern element having a multiplicity of discrete discontinuities therein each surrounded by said ink composition and spaced about substantially the entire surface thereof and through which said sheet material and film are in direct surface contact and substantially permanently bonded together by heat and pressure, the smallest dimension of each of said discontinuities being about one thirty-second to one-fourth inch, the total void area defined by said discontinuities being about 4.0 to 50.0 percent of the total area of said pattern element, said thermoformed article having at least one wall portion extending at an angle to other portions thereof.
Claim 3
Dependent Claim
43 words
The article of claim 1 wherein said discontinuities are of discrete circular configuration having a diameter of about one thirty-second to one-eighth inch and wherein said total void area is about 6.0 to 20.0 percent of the total area of said pattern element.
Claim 4
Dependent Claim
29 words
The article of claim 2 wherein said discontinuities are in a staggered pattern to resist peeling of said film along substantially any radius of substantially any of said discontinuities.
Claim 5
Dependent Claim
12 words
The article of claim 2 wherein said thermoplastic polymers are ethylene polymers.
Claim 6
Dependent Claim
22 words
The article of claim 4 wherein said film is surface treated to enhance the bond with said ink composition and sheet material.
Claim 7
Dependent Claim
13 words
The article of claim 1 wherein said sheet material is about 15- 300-mils-thick.
Claim 8
Dependent Claim
24 words
The article of claim 6 wherein said article is a swimming pool or the like having a bottom wall and a sidewall extending thereabout.
