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.

Claims (21)

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 disposed between the body and the flexible top, 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 deformable slider further comprises a pull tab, the flexible top is sealed to the body top surface with the pull tab sealed between the body top surface and the flexible top, and the pull tab is configured such that, after opening the blister package by peeling away the flexible top to expose the pull tab, the pull tab can be pulled to pull taut the deformable slider and lift the lens support.

2. The blister package of claim 1 , wherein the deformable slider comprises a unitary sheet of material.

3. 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.

4. The blister package of claim 1 , wherein the pull tab comprises a rail, the body comprises a groove, the rail is slidable in the groove, and the pulling the pull tab comprises sliding the rail of the pull tab in the groove.

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

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

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

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

9. 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; 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, the lens support is lifted away from the bottom surface, wherein the deformable slider further comprises a pull tab, the sealing the flexible top to the body top surface comprises sealing the pull tab between the body top surface and the flexible top, and the method further comprises:

opening the blister package by peeling away the flexible top; and

pulling the pull tab to pull taut the deformable slider and lift the lens support.

10. The method of claim 9 , further comprising:

opening the blister package by peeling away the flexible top; and

pulling taut the deformable slider to lift the lens support.

11. The method of claim 9 , wherein the pull tab comprises a rail, the body comprises a groove, the rail is slidable in the groove, and the pulling the pull tab comprises sliding the rail of the pull tab in the groove.
