Abstract

A blister package for a contact lens is provided. A deformable slider supporting a lens is movable via pull-tab or hinge to lift the contact lens out of a lens well. The deformable slider can include a hinge connected to a flexible peel-away top of the blister package or connected to a pull tab that can be pulled to pull taut the deformable slider. A blister package is also provided that includes a hinged shell having a lateral opening opposite the hinge, and a deformable slider that is folded over onto itself and seals both a top chamber and a bottom chamber. By pulling a tongue of the deformable slider, which extends from the lateral opening, the deformable slider can be removed from the closed shell and the closed shell can be opened enabling access to the contact lens.

First claim

What is claimed is:

1. A blister package for a contact lens, the blister package comprising:
a body, the body comprising a handle, a well connected to the handle, and a body top surface, the well having a perimeter and an inner sidewall defining a bottom surface;
a flexible top contacting the body top surface around the perimeter of, and closing, the well, the flexible top having a peel tab and being peelable away from the body to open the well; and
a deformable slider comprising a lens support, wherein the deformable slider is a unitary or multi-layer sheet of material and disposed between the body and the flexible top, the deformable slider is in a loose condition and the lens support is disposed in the well and adjacent the bottom surface, and the deformable slider is configured such that, by pulling the deformable slider, the lens support is lifted away from the bottom surface, wherein the blister package is configured such that, by peeling the flexible top away from the body, the deformable slider is pulled taut to a stretched-out position and the lens support is lifted away from the bottom surface.

2. The blister package of claim 1 , wherein the deformable slider is connected to both the flexible top and the lens support.

3. The blister package of claim 1 , wherein the deformable slider further comprises a hinge, wherein the hinge is connected to both the flexible top and the lens support.

4. The blister package of claim 3 , wherein the blister package is configured such that, by peeling the flexible top away from the body, the hinge is pulled taut causing the lens support to be lifted away from the bottom surface.

5. The blister package of claim 4 , wherein the peel tab of the flexible top contacts the body on a first side of the well, the hinge is connected to the flexible top adjacent a second side of the well, the second side is opposite the first side, and the blister package is configured such that, by peeling the flexible top away from the body, the well is exposed prior to the hinge being pulled taut and pulling the flexible top in a direction from the first side to the second side causes the lens support to be lifted away from the bottom surface.

6. The blister package of claim 1 , wherein the deformable slider is separate from the flexible top and peeling the flexible top away from the body exposes the deformable slider.

7. The blister package of claim 1 , wherein the lens support has a circular shape and a diameter and comprises a compressible foam material.

8. The blister package of claim 1 , wherein the deformable slider comprises a foil material.

9. The blister package of claim 1 , wherein each of the flexible top and the deformable slider independently comprises a foil material.

10. The blister package of claim 1 , further comprising a contact lens in the well and supported by the lens support.

11. A method comprising:
placing a contact lens into a well of a blister package, on top of a lens support of a deformable slider, the blister package comprising a body having a handle, a well connected to the handle, and a body top surface, the well having a perimeter and an inner sidewall defining a bottom surface, wherein the deformable slider is in a loose condition; and
sealing a flexible top to the body top surface to seal the well with the contact lens therein on top of the lens support, the sealing comprising sealing the flexible top such that the flexible top contacts the body top surface around the perimeter of the well and closes the well, the flexible top having a peel tab and being peelable away from the body to open the well,
wherein the lens support is disposed in the well and adjacent the bottom surface, and the deformable slider is configured such that, by pulling the deformable slider taut to a stretched-out position, the lens support is lifted away from the bottom surface.

12. The method of claim 11 , wherein the deformable slider further comprises a hinge, the hinge is connected to the both the lens support and to the flexible top, and the method further comprises pulling the pull tab to (1) peel the flexible top away from the body top surface, (2) open the well, (3) pull taut the hinge, and (4) lift the lens support away from the bottom surface.

13. The method of claim 11 , further comprising:
opening the blister package by peeling away the flexible top; and
pulling taut the deformable slider to a stretched-out position to lift the lens support.

14. The method of claim 11 , wherein the deformable slider is connected to the flexible top, and the method further comprises pulling the pull tab to peel away the flexible top from the body top surface and lift the lens support away from the bottom surface.
