Abstract

A blister package for a contact lens is provided and has a body and a seal. The body includes a handle and a deformable bowl. The seal seals the deformable bowl at a bowl top opening. The handle includes a lateral portion and an end portion. The end portion curves downwardly to a distal end that terminates at a plane. The bowl is recessed from a top surface of the body and the outer bottom surface of the bowl is arranged substantially on the same plane as the distal end of the handle. The design provides leverage in holding the blister package while a user deforms and inverts the bowl into a dome, presenting a contact lens on top of the dome in position for direct transfer to a person's finger or for application directly on an eye without the need for any finger contact.

First claim

What is claimed is:

1. A blister package for a contact lens, the blister package comprising a body and a seal, the body comprising a handle and a bowl, the body having a body top surface, a bowl top opening, and an outer bottom surface of the bowl, the seal sealing the bowl at the bowl top opening, wherein
the handle comprises a lateral portion and an end portion, the lateral portion extends laterally away from the bowl, the end portion is connected to the lateral portion and curves downwardly to a distal end, and the distal end of the handle terminates at a plane, and
the bowl is recessed from the body top surface, the outer bottom surface of the bowl is arranged substantially on the plane, the bowl comprises a deformable sidewall, the deformable sidewall is configured such that, with finger pressure, a user can hold the handle and upwardly push-up the bowl into the shape of a dome, and the deformable sidewall comprises a double-wall structure including an inelastically deformable inner wall that maintains the shape of the dome once inverted, and an elastically deformable outer wall that elastically rebounds to an original bowl shape after deformation.

2. The blister package of claim 1 , wherein the deformable sidewall comprises a foil.

3. The blister package of claim 1 , wherein the body top surface defines a bowl perimeter sealing surface, and the seal comprises a sheet of material defining a seal portion and a flap, wherein the seal portion contacts the bowl perimeter sealing surface around the top opening of the bowl, the flap is configured to form a pull tab, and the pull tab is configured to be pulled so that the seal portion can be separated from the bowl perimeter sealing surface and the bowl can be opened.

4. The blister package of claim 3 , wherein the seal portion has a shape and the flap has a shape that mirrors the shape of the seal.

5. The blister package of claim 3 , wherein the seal comprises aluminum foil.

6. The blister package of claim 3 , wherein the handle comprises a top surface and the seal portion is adhered to the body at the body top surface and along a portion of the top surface of the handle.

7. The blister package of claim 3 , wherein the body has a maximum width and the pull tab has a width that is equal to the maximum width.

8. The blister package of claim 1 , wherein the bowl contains a contact lens, and the flap comprises indicia thereon pertaining to a prescription of the contact lens.

9. The blister package of claim 1 , wherein drainage through-holes are formed through the inelastically deformable inner wall, and the blister package is configured such that, after inversion, as the elastically deformable outer wall rebounds to its original position after inversion, a suction is created drawing contact lens solution from the inverted inner wall through the drainage through-holes and into a bowl formed from the once-again-bowl-shaped outer wall.

10. An assembly comprising a plurality of blister packages, each blister package comprising a blister package of claim 1 , wherein each blister package has a bowl end and a handle end, and the blister packages are alternately arranged such that, for each adjacent pair of blister packages, the bowl end of one blister package is arranged next to the handle end of the other blister package of the pair.

11. A method of opening a blister package for a contact lens, the blister package comprising a body and a seal, the body comprising a handle and a bowl, the body having a body top surface, a bowl top opening, and an outer bottom surface of the bowl, the seal sealing the bowl at the bowl top opening, wherein
the handle comprises a lateral portion and an end portion, the lateral portion extends laterally away from the bowl, the end portion is connected to the lateral portion and curves downwardly to a distal end, and the distal end of the handle terminates at a plane, and
the bowl is recessed from the body top surface, the outer bottom surface of the bowl is arranged substantially on the plane, the bowl comprises a deformable sidewall, the deformable sidewall is configured such that, with finger pressure, a user can hold the handle and upwardly push-up the bowl into the shape of a dome, and the deformable sidewall comprises a double-wall structure including an inelastically deformable inner wall that maintains the shope of the dome once inverted and an elastically deformable outer wall that elastically rebounds to an original bowl shape after deformation, and
the method comprises:
pulling the seal to open the bowl at the howl top opening; and
pushing the outer bottom surface of the bowl upwardly and into the shape of a dome.

12. The method of claim 11 , further comprising holding the end portion of the handle between a thumb and a finger of a first hand, wherein the pushing the outer bottom surface of the bowl upwardly and into the shape of a dome comprises pushing with a finger of a second hand.

13. The method of claim 11 , further comprising holding only the end portion of the handle by pinching between a thumb and a finger of a first hand, wherein the pushing the outer bottom surface of the bowl upwardly and into the shape of a dome comprises pushing with a finger of a second hand.

14. The method of claim 11 , wherein the blister package comprises a drain for draining the bowl as the bowl is pushed-up into the shape of a dome, and the method further comprises draining contact lens solution while inverting the bowl into the shape of a dome.
