Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
153 words
A method of injection molding a composite plastic identification card body comprising: in succession, injecting a first plastic resin portion into an injection mold to delimit a first portion only of the card body, said first portion including a recess; permitting the first resin portion to solidify in the mold; then while the first resin portion is in the mold injecting into the mold at least a second plastic resin portion to delimit at least a portion of the remainder of the card body including filling said recess; then permitting the at least second resin portion to solidify in the mold; then removing the composite card body from the mold, wherein one of the plastic resin portions is incompatible with the other, and whereby one solidified resin portion may be separated from the other after the composite card body is removed from the mold to thereby leave a recess in the card body.
Claim 2
Independent Claim
153 words
A method of injection molding a composite plastic identification card body comprising: in succession, injecting a first plastic resin portion into an injection mold to delimit a first portion only of the card body, said first portion including a recess; permitting the first resin portion to solidify in the mold; then while the first resin portion is in the mold injecting into the mold at least a second plastic resin portion to delimit at least a portion of the remainder of the card body including filling said recess; then permitting the at least second resin portion to solidify in the mold; then removing the composite card body from the mold, wherein one of the plastic resin portions is incompatible with the other, and whereby one solidified resin portion may be separated from the other after the composite card body is removed from the mold to thereby leave a recess in the card body.
Claim 3
Independent Claim
140 words
A method of injection molding a composite plastic identification card body comprising: in succession, injecting a first plastic resin portion into an injection mold and solidifying said first resin portion to form at least a partial first layer of said card body; then while the first resin portion is in the mold injection into the mold a second plastic resin portion and solidifying said second resin portion to form at least a partial second layer of said card body; then injecting into the mold and solidifying a third plastic resin portion to form a third layer of said card body overlying said second layer; said second layer being molded so as to extend through said first and third layers to the respective outer surfaces of said first and third layers; and then removing the composite card body from the mold.
Claim 4
Independent Claim
140 words
A method of injection molding a composite plastic identification card body comprising: in succession, injecting a first plastic resin portion into an injection mold and solidifying said first resin portion to form at least a partial first layer of said card body; then while the first resin portion is in the mold injection into the mold a second plastic resin portion and solidifying said second resin portion to form at least a partial second layer of said card body; then injecting into the mold and solidifying a third plastic resin portion to form a third layer of said card body overlying said second layer; said second layer being molded so as to extend through said first and third layers to the respective outer surfaces of said first and third layers; and then removing the composite card body from the mold.
Claim 5
Dependent Claim
31 words
The method as claimed in claim 2, wherein said second layer is molded so that it extends through said first and third layers at the same location in the card body.
Claim 6
Dependent Claim
41 words
The method as claimed in claim 3, wherein said second resin portion is selected from plastic resins that are transparent when solidified and said first and third plastic resin portions are selected from plastic resins that are not transparent when solidified.
Claim 7
Dependent Claim
41 words
The method as claimed in claim 4, including selecting said first plastic resin portion so that it is opaque when solidified and colored black, and selecting said third plastic resin portion so that it is opaque when solidified and colored white.
Claim 8
Independent Claim
173 words
A method of injection molding a composite plastic identification card body comprising: in succession, injecting a first plastic resin portion into an injection mold to form a transparent first card layer; permitting the first resin portion to solidify in the mold; then while the first resin portion is in the mold injecting into the mold at least a second plastic resin portion to form an opaque second layer extending over said first layer; then permitting the at least second resin portion to solidify in the mold; and injecting and solidifying a third plastic resin portion using a resin that forms a third card layer that is transparent and overlies said second card layer; said second card layer being molded with varied thickness that is opaque to different degrees and thereby exhibits dark and light areas when observed in incident light, with the dark areas being reversed to light areas and the light areas being reversed to dark areas when observed in transmitted light; and then removing the composite card body from the mold.
Claim 9
Independent Claim
173 words
A method of injection molding a composite plastic identification card body comprising: in succession, injecting a first plastic resin portion into an injection mold to form a transparent first card layer; permitting the first resin portion to solidify in the mold; then while the first resin portion is in the mold injecting into the mold at least a second plastic resin portion to form an opaque second layer extending over said first layer; then permitting the at least second resin portion to solidify in the mold; and injecting and solidifying a third plastic resin portion using a resin that forms a third card layer that is transparent and overlies said second card layer; said second card layer being molded with varied thickness that is opaque to different degrees and thereby exhibits dark and light areas when observed in incident light, with the dark areas being reversed to light areas and the light areas being reversed to dark areas when observed in transmitted light; and then removing the composite card body from the mold.
