Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
144 words
An apparatus for attaching at least one label to the outer surface of a blow-molded article during the formation of said article, said apparatus comprising: (a) means for forming a parison from a heated mass of thermoplastic material, said parison having an outer surface; (b) means for tangentially attaching said label to said outer surface of said parison; (c) means for placing said parison with said tangentially attached label inside a blow mold cavity having an interior surface; (d) means for expanding said parison with said tangentially attached label such that said outer surface of said parison and said tangentially attached label come into contact with said interior surface of said blow mold cavity, whereby said label is attached to said outer surface of said blow-molded article; and (e) means for removing said blow-molded article with said attached label from said blow mold cavity.
Claim 2
Independent Claim
144 words
An apparatus for attaching at least one label to the outer surface of a blow-molded article during the formation of said article, said apparatus comprising: (a) means for forming a parison from a heated mass of thermoplastic material, said parison having an outer surface; (b) means for tangentially attaching said label to said outer surface of said parison; (c) means for placing said parison with said tangentially attached label inside a blow mold cavity having an interior surface; (d) means for expanding said parison with said tangentially attached label such that said outer surface of said parison and said tangentially attached label come into contact with said interior surface of said blow mold cavity, whereby said label is attached to said outer surface of said blow-molded article; and (e) means for removing said blow-molded article with said attached label from said blow mold cavity.
Claim 3
Dependent Claim
16 words
The apparatus recited in claim 1 wherein said means for forming a parison comprises an extruder.
Claim 4
Dependent Claim
17 words
The apparatus recited in claim 1 wherein said means for forming a parison comprises an injection molder.
Claim 5
Dependent Claim
29 words
The apparatus recited in claim 1 wherein said means for expanding said parison with said tangentially attached label comprises a nozzle for injecting said parison with a pressurized gas.
Claim 6
Dependent Claim
25 words
The apparatus recited in claim 1 wherein said means for expanding said parison comprises a source of pressurized gas in fluid communication with said parison.
Claim 7
Dependent Claim
29 words
The apparatus recited in claim 1 wherein said means for expanding said parison comprises a vacuum source in fluid communication with the interior surface of said blow mold cavity.
Claim 8
Independent Claim
183 words
An apparatus for making a blow-molded article having an outer surface with at least one label attached thereto at a final predetermined location, said label having been attached to the outer surface of a parison at an initial predetermined location prior to expanding said parison into said blow-molded article, said apparatus comprising: (a) means for forming said parison from a heated mass of thermoplastic material, said parison having said outer surface; (b) means for tangentially attaching said label to said outer surface of said parison at said initial predetermined location; (c) means for placing said parison with said tangentially attached label inside a blow mold cavity having an interior surface; (d) means for expanding said parison with said tangentially attached label such that said outer surface of said parison and said tangentially attached label come into contact with said interior surface of said blow mold cavity, whereby said label is attached to said outer surface of said blow-molded article at said final predetermined location; and (e) means for removing said blow-molded article having said label attached thereto at said final predetermined location thereto.
Claim 9
Independent Claim
183 words
An apparatus for making a blow-molded article having an outer surface with at least one label attached thereto at a final predetermined location, said label having been attached to the outer surface of a parison at an initial predetermined location prior to expanding said parison into said blow-molded article, said apparatus comprising: (a) means for forming said parison from a heated mass of thermoplastic material, said parison having said outer surface; (b) means for tangentially attaching said label to said outer surface of said parison at said initial predetermined location; (c) means for placing said parison with said tangentially attached label inside a blow mold cavity having an interior surface; (d) means for expanding said parison with said tangentially attached label such that said outer surface of said parison and said tangentially attached label come into contact with said interior surface of said blow mold cavity, whereby said label is attached to said outer surface of said blow-molded article at said final predetermined location; and (e) means for removing said blow-molded article having said label attached thereto at said final predetermined location thereto.

Claim 12
Dependent Claim
29 words
The apparatus recited in claim 7 wherein said means for expanding said parison with said tangentially attached label comprises a nozzle for injecting said parison with a pressurized gas.
Claim 13
Dependent Claim
25 words
The apparatus recited in claim 7 wherein said means for expanding said parison comprises a source of pressurized gas in fluid communication with said parison.
Claim 14
Dependent Claim
29 words
The apparatus recited in claim 7 wherein said means for expanding said parison comprises a vacuum source in fluid communication with the interior surface of said blow mold cavity.
