Abstract

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.

First claim

The invention claimed is:

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.
