Contact lens blister pack label and method for adjoining blister packs
Contact lens packaging ( 2 ) includes two or more individual, sealed blister packs ( 1 ) coupled together by a connecting label ( 5 ), which includes a uni-axial shear polymer film ( 6 ). The connecting label ( 5 ) is arranged and oriented such that the tear direction of the polymer film ( 6 ) is parallel to a line (A) bisecting adjacent blister packs ( 1 ). Methods of binding together two or more blister packs ( 1 ) are also described.
1. Packaging for contact lenses comprising at least two individual, sealed blister packs and a connecting label comprising a polymer film, each of the at least two individual, sealed blister packs including a plastic base member housing a single contact lens and packaging solution, and a sealing member; wherein the connecting label is adhered to the sealing members of each of the at least two individual, sealed, blister packs to bind the blister packs together; and wherein the polymer film is a uni-axial shear polymer film, the connecting label being arranged and oriented such that a tear direction of the polymer film lies parallel to a line bisecting adjacent blister packs, and wherein said at least two individual, sealed blister packs are not connected together by said sealing members.
2. The packaging of claim 1 wherein the polymer film is a co-extruded, multilayer film.
3. The packaging of claim 1 wherein the uni-axial shear polymer film is a corona treated polyolefin film.
4. The packaging of claim 1 , wherein a surface of the connecting label bears a printed image.
5. The packaging of claim 1 , wherein the connecting label is adhered to the surface members of the blister packs with an adhesive.
6. The packaging of claim 1 , wherein the blister packs have a planar upper surface and the connecting label is adhered to the planar upper surface of the at least two individual, sealed blister packs.
7. The packaging of claim 1 , wherein the connecting label extends across three blister packs.
8. The packaging of claim 1 wherein the connecting label has a longest dimension of at least 70 mm.
9. The packaging of claim 2 wherein the uni-axial shear polymer film is a corona treated polyolefin film.
10. The packaging of claim 2 , wherein a surface of the connecting label bears a printed image.
11. The packaging of claim 2 , wherein the blister packs have a planar upper surface and the connecting label is adhered to the planar upper surface of the at least two individual, sealed blister packs.
12. The packaging of claim 2 , wherein the connecting label extends across three blister packs.
13. A method of binding together at least two individual, sealed contact lens blister packs, each of the at least two individual, sealed blister packs comprising a plastic base member housing a single contact lens, and a sealing member; the method comprising a step of orientating a connecting label, comprising a uni-axial shear polymer film, such that the tear direction of the label lies parallel to a line connecting adjacent blister packs; and applying the label to the sealing members of two or more adjacent blister packs to bind the blister packs together.
14. The method of claim 13 wherein the uni-axial shear polymer film is a co-extruded, multilayer film.
15. The method of claim 13 wherein the uni-axial shear polymer film is a corona treated polyolefin film.
16. The method of claim 13 , wherein a surface of the connecting label bears a printed image.
17. The method of claim 13 , comprising the step of adhering the connecting label to the surface members of the two or more blister packs with an adhesive.
18. The method of claim 13 , wherein the blister packs have a planar upper surface and the connecting label is applied to the planar upper surface of the at least two individual, sealed blister packs.
19. The method of claim 13 , wherein the connecting label is applied across the sealing members of three blister packs.
20. The method of claim 13 , wherein the connecting label has a longest dimension of at least 70 mm.
