Abstract
Abstract Various embodiments of an imprintable tape and a preferred method for forming and imprinting the tape are disclosed. Generally, the tape includes an opaque film portion formed from polytetrafluoroethylene and a layer of material of contrasting color laminated to the opaque film so that upon application of compressive force to a selected surface portion of the film, unique characteristics of the polytetrafluoroethylene in the opaque film cause it to become transparent within the selected surface portion and thereby form a contrasting indicia or design by the resulting exposure of the underlying tape or surface. Another embodiment of the tape employs an underlying surface to which the tape is applied for forming the contrasting indicia or design exposed by compressing part of the tape. Various embodiments are disclosed for forming a contrasting colored surface beneath the opaque film. In addition, the embodiments also include an adhesive layer covered by a removable or peelable backing for securing the tape to a surface. The various embodiments also preferably comprise a protective film overlying the opaque polytetrafluoroethylene film.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
112 words
A tape adapted for imprinting of indicia upon selected surface portions thereof, comprising an opaque film formed from polytetrafluoroethylene and having a top surface and a bottom surface, a layer of material being laminated to the bottom surface of said opaque film, said layer having a contrasting color underlying the opaque film in the selected surface portions of the tape whereby, upon application of compression force to the selected surface portions of the laminated tape, corresponding portions of said opaque film are compressed without any lateral displacement and thereby converted to a transparent condition in order to expose the underlying contrasting color of said laminated layer and thereby form the imprinted indicia.
Claim 2
Dependent Claim
112 words
A tape adapted for imprinting of indicia upon selected surface portions thereof, comprising an opaque film formed from polytetrafluoroethylene and having a top surface and a bottom surface, a layer of material being laminated to the bottom surface of said opaque film, said layer having a contrasting color underlying the opaque film in the selected surface portions of the tape whereby, upon application of compression force to the selected surface portions of the laminated tape, corresponding portions of said opaque film are compressed without any lateral displacement and thereby converted to a transparent condition in order to expose the underlying contrasting color of said laminated layer and thereby form the imprinted indicia.
Claim 3
Dependent Claim
24 words
The laminated tape of claim 1 wherein the opaque film is relatively light in color and the laminated layer is relatively dark in color.
Claim 4
Dependent Claim
29 words
The laminated tape of claim 1 further comprising an adhesive surface and a removable backing over the adhesive surface to facilitate application of the tape to a selected surface.
Claim 5
Dependent Claim
34 words
The laminated tape of claim 1 wherein said laminated tape includes an adhesive surface opposite said opaque film and further comprising a peelable backing for selectively exposing the adhesive surface of said laminated layer.
Claim 6
Dependent Claim
42 words
The laminated tape of claim 1 wherein the laminated layer comprises a clear film and a colored adhesive opposite the opaque film and further comprising a peelable backing over the colored adhesive to facilitate application of the tape to a selected surface.
Claim 7
Dependent Claim
19 words
The laminated tape of claim 1 wherein said laminated layer is formed from a film of said contrasting color.
Claim 8
Dependent Claim
30 words
The laminated tape of claim 1 further comprising a clear film laminated to the opaque film opposite the laminated layer to serve as a protective layer for the opaque film.
