Abstract
Abstract There is provided a tamper proof label system consisting of an adhesive printable fragile label base and an overlapping transparent adhesive self-supporting protective film. The surface of the label is printable and at least a portion is masked with a material having essentially no adhesivity for the protective film. In use, the label base is printed and applied to a substrate and the adhesive protective film applied as an overlapping overlay to protect but not support the imprinted surface. Removal of the adhesive overlay film will expose the fragile label which cannot be removed from the substrate without destroying the physical integrity of the label base. Simultaneous removal of both results in a separation of the overlay film from the label base.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
147 words
A destructible label system comprising: a. a fragile label base at least one surface of which is imprintable with visual indicia; b. an adhesive layer having first adhesive surface for adhesive contact with the surface opposed to the imprintable surface of the fragile label base and a second adhesive surface for adhesive contact with at least one substrate, the adhesivity of the second adhesive surface to the substrate exceeding the tear strength of said fragile label base; and c. a self-supporting film at least transparent where visual indicia are to appear on said fragile label base said selfsupporting film dimensioned to cover said fragile label base in overlapping relationship and having an adhesive surface for contact with said fragile label base and the substrate a portion of the adhesive surface of said self-supporting film being substantially non-adhesive with respect to a portion of said fragile label base.
Claim 2
Dependent Claim
147 words
A destructible label system comprising: a. a fragile label base at least one surface of which is imprintable with visual indicia; b. an adhesive layer having first adhesive surface for adhesive contact with the surface opposed to the imprintable surface of the fragile label base and a second adhesive surface for adhesive contact with at least one substrate, the adhesivity of the second adhesive surface to the substrate exceeding the tear strength of said fragile label base; and c. a self-supporting film at least transparent where visual indicia are to appear on said fragile label base said selfsupporting film dimensioned to cover said fragile label base in overlapping relationship and having an adhesive surface for contact with said fragile label base and the substrate a portion of the adhesive surface of said self-supporting film being substantially non-adhesive with respect to a portion of said fragile label base.
Claim 3
Dependent Claim
17 words
A destructible label system as claimed in claim 1 in which the fragile base layer is friable.
Claim 4
Dependent Claim
17 words
A destructible label system as claimed in claim 1 in which the fragile base layer is brittle.
Claim 5
Dependent Claim
167 words
A destructible label system comprising: a. a fragile label base at least one surface of which is imprintable with visual indicia; b. a masking surface in contact with a portion of the printable surface; c. an adhesive layer having a first adhesive surface for adhesive contact with the surface of said fragile label base opposed to the imprintable surface and a second adhesive surface adapted for adhesive contact with at least one substrate, the adhesivity of said second adhesive surface to the substrate exceeding the tear strength of said fragile label base; d. a self-supporting film at least transparent where visual indicia are to appear on said fragile label base, said self-supporting film dimensioned to cover said fragile label base in overlapping relationship and having adhesive surface for contact with said masking surface, said fragile label base and the substrate to which the label is to be applied said masking surface preventing adhesive contact of said adhesive surface with the masked portion of said fragile label base.
Claim 6
Dependent Claim
167 words
A destructible label system comprising: a. a fragile label base at least one surface of which is imprintable with visual indicia; b. a masking surface in contact with a portion of the printable surface; c. an adhesive layer having a first adhesive surface for adhesive contact with the surface of said fragile label base opposed to the imprintable surface and a second adhesive surface adapted for adhesive contact with at least one substrate, the adhesivity of said second adhesive surface to the substrate exceeding the tear strength of said fragile label base; d. a self-supporting film at least transparent where visual indicia are to appear on said fragile label base, said self-supporting film dimensioned to cover said fragile label base in overlapping relationship and having adhesive surface for contact with said masking surface, said fragile label base and the substrate to which the label is to be applied said masking surface preventing adhesive contact of said adhesive surface with the masked portion of said fragile label base.
