Abstract
Abstract A time color indicator and method are provided. The time color indicator includes a base layer segment having a transparent impermeable layer, a substantially non-curing opaque coating, and a release sheet. A portion of the uncoated surface of the transparent layer bears a printed area including a camouflage pattern printed with non-migrating ink and a message segment printed with migrating ink. An indicator layer segment includes a transparent impermeable layer, a substantially non-curing opaque coating, and a release sheet partially folded back to form a finger gripping tab and expose an indicator layer coating portion which contacts and adheres to the base layer adjacent the printed area. The time color indicator is activated by pulling the finger tab to remove the release sheet, causing the indicator layer coating to cover and contact the printed area, with the message segment migrating through the indicator layer coating. In the method of the invention both the base layer segment and indicator layer segment may be formed in the same process steps from a single web of transparent polyester film, the base layer being printed with the message and the indicator layer segment being divided from the web and superimposed over and adhered to the base segment.

Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
99 words
A time color indicator comprising: a base layer bearing on a portion thereof a message printed with an ink containing a migrating agent; an activation layer having a transparent layer, a substantially non-curing coating, and a release sheet covering a portion of said non-curing coating, said activation layer assuming a first, non-activated position with the exposed portion of said coating contacting said base layer adjacent to said printed portion, and said release sheet being disposed adjacent said printed portion, said actuation layer assuming a second, activated position with said release sheet removed and said coating contacting said printed portion.
Claim 2
Dependent Claim
15 words
The apparatus according to Claim 1, wherein said release sheet further comprises a gripping tab.
Claim 3
Dependent Claim
38 words
The apparatus of Claim 1, wherein said base layer further comprises a transparent impermeable layer with a substantially non-curing base layer coating and base layer release sheet disposed on the base layer surface opposite to said printed portion.
Claim 4
Dependent Claim
14 words
The apparatus of claim 3, wherein said transparent impermeable layer is a clear polyester.
Claim 5
Dependent Claim
15 words
The apparatus of Claim 4, wherein said base layer coating is a plasticizer-vinyl-titanium dioxide mixture.
Claim 6
Dependent Claim
13 words
The apparatus of Claim 1, wherein said transparent layer is a clear polyester.
Claim 7
Dependent Claim
15 words
The apparatus of Claim 6, wherein said activation layer coating is a plasticizer-vinyl-titanium dioxide mixture.
Claim 8
Dependent Claim
37 words
The apparatus of Claim 1, wherein said printed portion further comprises a non-migrating printed component printed with an ink not containing a migrating agent and a migrating printed component printed with an ink containing a migrating agent.
Claim 9
Dependent Claim
24 words
The apparatus of Claim 8, wherein said non-migrating printed component camouflages said migrating printed component when said activation layer assumes said first, non-activated position.
Claim 10
Dependent Claim
29 words
The apparatus of Claim 1, wherein said migrating agent migrates through said non-curing coating in less than about ten minutes when said actuation layer assumes said second, activated position.
Claim 11
Independent Claim
115 words
A method of making a time color indicator comprising the steps of: providing a base layer having first and second surfaces; printing a portion of said first base layer surface with an ink containing a migrating agent; forming an indicator layer by, (i) providing a transparent layer; (ii) coating one surface of said transparent layer with a substantially non-curing indicator layer coating; (iii) disposing a release sheet over a portion of said coating; (iv) assembling said base layer and said indicator layer into a first, nonactivated position by contacting the exposed portion of said coating to said base layer adjacent to said printed portion, so that said release sheet is disposed adjacent said printed portion.
Claim 12
Dependent Claim
49 words
The method of Claim 11 further comprising the steps of activating said time color indicator by removing said release sheet and causing said indicator layer coating to substantially overlie said printed portion so that said migrating agent is transferred through said indicator layer coating to display a desired message.
Claim 13
Dependent Claim
59 words
The method of Claim 11 wherein said printing step further comprises: printing a camouflage pattern onto said base layer with an ink not containing a migrating agent; and printing a message to be displayed onto said base layer with an ink containing a migrating agent, said camouflage pattern concealing said message when said activation layer assumes said non-activated position.
Claim 14
Dependent Claim
31 words
The method of Claim 11, wherein said step of forming an indicator layer further comprises the additional step of folding a portion of said release sheet to form a gripping tab.
Claim 15
Dependent Claim
22 words
The method according to Claim 11, wherein said step of providing a transparent indicator layer further comprises providing a clear polyester layer.
Claim 16
Dependent Claim
25 words
The method according to Claim 11, wherein said coating step further comprises coating one surface of said transparent layer with a mixture of plasticizer-vinyl-titanium dioxide.
Claim 17
Dependent Claim
39 words
The method according to Claim 11, wherein said step of providing a base layer further comprises providing a transparent layer having first and second surfaces, and coating said second surface opposite said printed area with a substantially non-curing coating.
Claim 18
Dependent Claim
15 words
The method of Claim 17, wherein said base layer coating is a plasticizer-vinyl-titanium dioxide mixture.
Claim 19
Independent Claim
121 words
A method of making a time color indicator comprising: providing a transparent impermeable web; coating a first surface of said web with a substantially non-curing coating; disposing a release sheet over said coating; printing an area of the second surface of said web, at least a portion of said printed area containing a migrating agent; dividing said web longitudinally to form a base layer segment bearing said printed area and an indicator layer segment; removing a portion of said indicator segment release sheet to expose a portion of said indicator segment coating; disposing said indicator segment over said base layer segment with said exposed indicator segment coating contacting and adhering to said base segment first surface adjacent to said printed area.
Claim 20
Dependent Claim
40 words
The method of Claim 19, wherein said printing step further comprises the steps of: printing a camouflage pattern with an ink not containing a migrating agent; and printing a message to be displayed with an ink containing a migrating agent.
Claim 21
Dependent Claim
