Security packaging
View Patent ↗A security packaging provides multi-layer laminate structure for providing evidence of package tampering. The packaging may include a first panel having an opening therein in planar contact with an insert member and a film layer. The film layer may include a pattern layer that may be adhered to the film layer via an adhesion layer. A second adhesion layer may be placed onto the pattern layer to adhere the pattern layer to the insert member.
1. A tamper evident packaging comprising:
a first panel having an opening therein;
a film with first and second surfaces that is at least partially transparent overlaying the opening in the first panel so that the first surface opposes the first panel;
a pattern layer having a top surface and bottom surface placed onto the second surface of the film via a first adhesion layer that contacts the top surface of the pattern layer adjacent the film;
a second adhesion layer placed in contact with the bottom surface of the pattern layer and a surface of an insert member;
wherein at least a portion of the first and second adhesion layers have a peel strength relative to the pattern layer that is higher than the peel strength relative to an adjacent surface so that upon separation of the insert member from the first panel the first and second adhesion layers each remove a portion of the pattern layer from the film or insert member thereby leaving an indicator visible through the opening and film that such separation has occurred.
2. The packaging of claim 1 further including a second panel so that the first and second panels are joined together.
3. The packaging of claim 1 , wherein cohesive failure is induced between the pattern layer and the film.
4. The packaging of claim 1 , wherein cohesive failure is induced between the pattern layer and the insert member.
5. The packaging of claim 3 , wherein the pattern layer includes a continuous configuration that is disrupted when the cohesive failure is induced between the pattern layer and any adjacent layer.
6. The packaging of claim 5 , wherein the continuous configuration is substantially prevented from being restored after the cohesive failure is induced between the pattern layer and any adjacent layer.
7. The packaging of claim 1 , wherein a portion of the first and second adhesion layers includes a release coating or adhesive deadener to cause the cohesive failure between the pattern layer and any adjacent layer.
8. The packaging of claim 1 , wherein the pattern layer includes a foil material.
9. The packaging of claim 1 , wherein the pattern layer is formed from a holographic foil.
10. The packaging of claim 1 , wherein a third adhesion layer adheres a least a portion of the film to at least a portion of the first panel.
11. The packaging of claim 10 , wherein the first, second and third adhesion layers each include an adhesive portion and cohesive failure portion.
12. The packaging of claim 11 , wherein the cohesive failure portion includes materials selected from a release coat, an adhesive deadener, a film or any combination thereof.
13. A method for packaging comprising:
providing a first panel having an opening therein;
layering a film with first and second surfaces that is at least partially transparent over the opening in the first panel so that the first surface opposes the first panel;
forming a pattern layer on the second surface of the film, a first adhesion layer being placed between the film and the pattern layer;
placing a second adhesion layer between the pattern layer and an insert member;
wherein at least a portion of the first and second adhesion layers have a peel strength relative to the pattern layer that is higher than the peel strength relative to an adjacent surface so that upon separation of the insert member from the first panel the first and second adhesion layers each remove a portion of the pattern layer from the film or insert member thereby leaving an indicator visible through the opening and film that such separation has occurred.
14. The method claim 13 , wherein cohesive failure is induced between the pattern layer and the film.
15. The method of claim 14 wherein cohesive failure is induced between the pattern layer and the insert member.
16. The method of claim 14 , wherein the pattern layer includes a continuous configuration that is disrupted when the cohesive failure is induced between the pattern layer and any adjacent layer.
17. The method of claim 16 , wherein the continuous configuration is substantially prevented from being restored after the cohesive failure is induced between the pattern layer and any adjacent layer.
18. The method of claim 13 , wherein a portion of the pattern layer includes a release coating or adhesive deadener to cause the cohesive failure between the pattern and the film.
19. The method of claim 13 , wherein a third adhesion layer adheres a least a portion of the film to at least a portion of the first panel.
20. A tamper evident packaging comprising:
a first panel having an opening therein;
a film with first and second surfaces that is at least partially transparent overlaying the opening in the first panel so that the first surface opposes the first panel;
a pattern layer having a top surface and bottom surface and a continuous configuration thereon, placed onto the second surface of the film via a first adhesion layer that contacts the top surface of the pattern layer adjacent the film;
a second adhesion layer placed in contact with the bottom surface of the pattern layer and a surface of an insert member;
wherein at least a portion of the first and second adhesion layers:
i. have a peel strength relative to the pattern layer that is higher than the peel strength relative to an adjacent surface so that upon separation of the insert member from the first panel the first and second adhesion layers each remove a portion of the pattern layer from the film or insert member thereby leaving an indicator visible through the opening and film that such separation has occurred;
ii. include an adhesive portion and cohesive failure portion, such that the cohesive failure portion includes materials selected from a release coat, an adhesive deadener, a film or any combination thereof.
