Abstract

A blister package for a contact lens is provided. The blister package includes a body defining a handle and a well, a flexible top contacting the body and closing the well, and a lens cradle that includes a lens support bowl. The lens cradle is attached to the inner surface of the flexible top. By peeling away the flexible top, the lens cradle is lifted away from the bottom surface of the well and the lens is raised out of the well, cradled by the lens support bowl, and presented for easy fingertip manipulation by a user.

First claim

What is claimed is:

1. A blister package for a contact lens, the blister package comprising:
a body, the body having a body top surface and comprising a handle and a well connected to the handle, 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 an inner surface and a peel tab and being peelable away from the body to open the well; and
a lens cradle attached to the inner surface of the flexible top, comprising a lens support bowl, and having an opening along a side thereof between an edge of the lens support bowl and the inner surface of the flexible top, wherein the lens support bowl is shaped and sized to fit within the well, is disposed between the body and the flexible top, and has an inner bowl surface, wherein a cradle volume is defined between the inner bowl surface and the inner surface of the flexible top and is configured to accommodate a portion of a contact lens, and the lens cradle and flexible top are configured such that, by pulling the flexible top away from the body top surface, the lens cradle is lifted away from the bottom surface of the well.

2. The blister package of claim 1 , wherein the inner bowl surface is concave.

3. The blister package of claim 1 , wherein the lens support bowl comprises a plurality of drainage through-holes.

4. The blister package of claim 1 , wherein the cradle volume is large enough to accommodate a major portion of a contact lens.

5. The blister package of claim 1 , wherein the lens cradle comprises a tab portion attached to the lens support bowl and adhered to the inner surface of the flexible top.

6. The blister package of claim 1 , wherein the lens support bowl has a hollow hemispherical shape.

7. The blister package of claim 1 , wherein the lens support bowl has a shape defined by a portion of a hollow hemisphere.

8. The blister package of claim 1 , wherein the lens support bowl has a shape comprising from about 50% to about 75% of a hemisphere.

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

10. The blister package of claim 1 , wherein the flexible top further comprises a peel tab that contacts the body on a first side of the well, and a hinge is connected to the flexible top adjacent a second side of the well, the second side being opposite the first side.

11. The blister package of claim 1 , wherein and the blister package is configured such that, by peeling the flexible top away from the body to expose the well, the lens cradle is lifted away from the bottom surface of the well.

12. The blister package of claim 1 , further comprising a contact lens in the cradle volume.

13. A method of packaging a contact lens in a blister package, the blister package comprising
a body, the body having a body top surface and comprising a handle and a well connected to the handle, the well having a perimeter and an inner sidewall defining a bottom surface,
a flexible top configured to contact the body top surface around the perimeter of the well, the flexible top having an inner surface and, once sealed to the body, a peel tab being peelable away from the body to open the well, and
a lens cradle attached to the inner surface of the flexible top, comprising a lens support bowl, and having an opening along a side thereof between an edge of the lens support bowl and the inner surface of the flexible top, wherein the lens support bowl is shaped and sized to fit within the well, is disposed between the body and the flexible top, and has an inner bowl surface, and a cradle volume is defined between the inner bowl surface and the inner surface of the flexible top, the method comprising:
placing a contact lens in the cradle volume; and
sealing the flexible top to the body top surface to seal the cradle with the contact lens, in the well.

14. The method of claim 13 , further comprising pulling the flexible top away from the body top surface to lift the lens cradle away from the well.

15. The method of claim 13 , further comprising pulling the flexible top away from the body top surface in a direction from the handle toward the well to lift the lens cradle away from the well.

16. The method of claim 13 , wherein the inner bowl surface is concave.

17. The method of claim 13 , wherein the lens support bowl comprises a plurality of drainage through-holes and the method comprises peeling the flexible top away from the body top surface to lift the cradle away from the bottom surface of the well, and draining contact lens solution from the cradle, through the drainage through-holes.
