Abstract

Abstract In accordance with the invention, an improved packaging system for protection against the theft of goods by overlabeling comprises a layer of packaging material surrounding the goods, a label adhered to the packaging material, and a transparent film covering the label. In contrast with conventional packaging, the outer surface of the transparent film is provided with an antiadhesive coating to inhibit overlabeling. The transparent film can be smooth or textured. The advantage of texturing, as by embossing, is to reduce the surface area to which an overlabel can adhere. The antiadhesive coating is preferably a composite layer comprising a non-adhesive base coating of silicone and a layer of "tack kill" material such as an acrylic plasticizer for neutralizing a subsequently applied adhesive. The result is that a spurious label applied on the film over the original label readily disengages in the course of ordinary package handling. In addition the adhesive underside of the film can be provided with a recognizable pattern of invisible ink to permit rapid detection of tampering.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 60 words
A labeled package comprising; a package, a label adhered to said package; and covering said label, an adhesive transparent film comprising a film of transparent material having two major surfaces, a coating of adhesive material on one major surface for adhering to said label and a coating of antiadhesive material on the other major surface for resisting theft by overlabeling.
Claim 2
Dependent Claim 60 words
A labeled package comprising; a package, a label adhered to said package; and covering said label, an adhesive transparent film comprising a film of transparent material having two major surfaces, a coating of adhesive material on one major surface for adhering to said label and a coating of antiadhesive material on the other major surface for resisting theft by overlabeling.
Claim 3
Dependent Claim 23 words
The labeled package of claim 1 wherein said transparent film is textured to reduce the area of contact for a subsequently applied label.
Claim 4
Dependent Claim 39 words
The labeling package of claim 1 wherein said coating of antiadhesive material comprises a composite coating comprising a non-adhesive coating of silicone and a coating of tack killing material for neutralizing the adhesive properties of a subsequently applied adhesive.
Claim 5
Dependent Claim 13 words
The labeled package of claim 3 wherein said tack-killing material comprises acrylic plasticizer.
Claim 6
Dependent Claim 22 words
The labeled package of claim 1 wherein a pattern of invisible ink is formed underlying the outer surface of said transparent film.
Claim 7
Dependent Claim 58 words
An adhesive transparent film for protecting a labeled package from theft by overlabeling comprising: an embossed film of transparent polymer, said film having two major surfaces, a coating of adhesive material on one major surface for adhering to said labeled package, and an antiadhesive coating on the other major surface for resisting adherence of a subsequently applied overlabel.
Claim 8
Dependent Claim 58 words
An adhesive transparent film for protecting a labeled package from theft by overlabeling comprising: an embossed film of transparent polymer, said film having two major surfaces, a coating of adhesive material on one major surface for adhering to said labeled package, and an antiadhesive coating on the other major surface for resisting adherence of a subsequently applied overlabel.
Claim 9
Dependent Claim 18 words
A film according to claim 6 further comprising a pattern of invisible ink underlying the antiadhesive coated surface.
Claim 10
Dependent Claim 21 words
A film according to claim 6 wherein said coating of antiadhesive material comprises a composite coating of silicone and acrylic plasticizer.
Claim 11
Dependent Claim 12 words
A film according to claim 6 wherein said transparent polymer comprises polypropylene.
Claim 12
Dependent Claim 23 words
A film according to claim 6 further comprising a layer of silicone-coated paper laminated to the adhesive coated surface for ease of handling.
