Abstract

A blister package for a contact lens is provided that can be stacked with other blister packages of the same design. One example of the blister package has a body that includes a dome and a handle. A seal is attached to the top surface of the body and has a seal dome that seals a volume between the outer sidewall of the body dome and the inner sidewall of the seal dome. The handle has a through-hole and the through-hole that accommodates the outer sidewall of the seal dome. Another blister package provided has a handle and a bowl and the handle has a through-hole that accommodates the bowl outer surface. Stacks of blister packages are also provided as is secondary packaging for packaging stacks of tessellating blister packages.

First claim

What is claimed is:

1. A blister package for a contact lens, the blister package comprising:
a body having a top surface and comprising a handle and a body dome connected to the handle, the body dome having a convex sidewall and an opposite concave sidewall; and
a seal attached to the top surface of the body, the seal having a seal top surface and comprising a seal dome having an outer convex sidewall and an inner concave sidewall, the seal sealing a volume between the convex sidewall of the body dome and the inner concave sidewall of the seal dome, the seal dome intersecting the seal top surface at an intersection, the seal dome having a diameter or other maximum dimension at the intersection, the handle having a body through-hole, the seal having a seal through-hole aligned with and a same size as the body through-hole, and the body through-hole and the seal through-hole having a through-hole diameter or other maximum dimension for at least partially accommodating the outer convex sidewall of the seal dome to permit stacking of a plurality of blister packages, wherein
the outer convex sidewall of the seal dome defines a blister package dome.

2. The blister package of claim 1 , further comprising a contact lens having a concave surface positioned on the convex sidewall of the body dome.

3. The blister package of claim 1 , wherein the through-hole diameter or other maximum dimension is the same size as the diameter or other maximum dimension of the blister package dome at the intersection.

4. The blister package of claim 1 , wherein the diameter or other maximum dimension at the intersection forms a maximum dimension of the blister package dome, and the through-hole diameter or other maximum dimension is at least as large as the maximum dimension of the blister package dome.

5. The blister package of claim 1 , wherein the body through-hole and the seal through-hole are circular through-holes, the circular through-holes having a diameter, the blister package dome has a diameter at the intersection, and the diameter of the circular through-holes is large enough to at least partially accommodate the blister package dome.

6. The blister package of claim 5 , wherein the diameter of the circular through-holes is at least 50% of the diameter at the intersection.

7. The blister package of claim 1 , wherein the seal comprises a tab extending into the seal through-hole.

8. The blister package of claim 7 , further comprising a contact lens enclosed within the volume, and wherein the tab is marked with indicia pertaining to a prescription of the contact lens.

9. The blister package of claim 1 , wherein the seal dome is reinforced with a layer of plastic material.

10. The blister package of claim 1 , wherein the body comprises a plastic material and the seal comprises a plastic material.

11. A stack of blister packages, each blister package of the stack comprising a blister package of claim 1 , wherein the body through-hole and the seal through-hole of a first of the blister packages is placed on, and at least partially around, the blister package dome of a second, adjacent, blister package of the blister packages of the stack.

12. The stack of blister packages of claim 11 , and a container, wherein each of the blister packages has an outer circumference, the outer circumferences all have the same profile, the container has an inner circumference having a profile, and the outer circumference profiles are complementary to the profile of the inner circumference.

13. The stack of blister packages of claim 11 , wherein adjacent blister packages of the stack are connected to one another along an edge of each such that the stack comprises a zig-zag configuration.

14. The blister package of claim 1 , wherein the body comprises a foil material and the seal comprises a foil material.

15. The blister package of claim 1 , wherein the body and the seal comprise foil material and the body dome is reinforced with a double layer of foil.
