Abstract

Described herein are devices and methods for storage and application of a contact lens. The device includes an applicator cap (102) including a handle portion (106a) having a first end, a second end, and a body that extends between the first end and the second end. The body includes at least one lever surface. The device includes a container (104) having a reservoir configured to house a contact lens and packaging solution. The at least one lever surface is configured to provide at least one leverage point for movement of the applicator cap relative to the container.

First claim

What is claimed is:

1 . A device for storage and application of a contact lens, the device comprising:
an applicator cap comprising a handle portion having a first end, a second end, and a body that extends between the first end and the second end, wherein the body comprises at least one lever surface; and a container having a reservoir configured to house a contact lens and packaging solution,
wherein the at least one lever surface is configured to provide at least one leverage point for movement of the applicator cap relative to the container.

2 . The device of claim 1 , further comprising a seal wrap disposed about the applicator cap and the container, wherein the seal wrap is configured to secure the applicator cap and the container together.

3 . The device of claim 1 , wherein the container comprises at least one seal surface, and
wherein the at least one seal surface of the container abuts the applicator cap when the device is in a closed configuration.

4 . The device of claim 1 , wherein the container comprises at least one seal surface, wherein the at least one seal surface of the container comprises an angular platform.

5 . The device of claim 1 , wherein the container comprises at least one seal surface, wherein the at least one seal surface of the container further comprises threads configured to engage with corresponding grooves of the applicator cap.

6 . The device of claim 1 , wherein the container comprises at least one seal surface, wherein the at least one seal surface of the container comprises a plurality of concentric circular seals.

7 . The device of claim 1 , wherein the container comprises polypropylene.

8 . The device of claim 1 , wherein the applicator cap comprises a convex surface opposite and spaced apart from the handle.

9 . The device of claim 8 , wherein the applicator cap further comprises a plurality of fins that define a plurality of reservoir channels in the convex surface of the applicator cap, and
wherein the reservoir channels are configured to retain packaging solution.

10 . The device of claim 8 , wherein the applicator cap comprises at least one seal surface, and
wherein the at least one seal surface of the applicator cap abuts the container when the device is in a closed configuration.

11 . The device of claim 8 , wherein the applicator cap comprises at least one seal surface, and
wherein the at least one seal surface of the applicator cap comprises a plurality of concentric circular seals.

12 . The device of claim 8 , wherein the applicator cap comprises at least one seal surface, and
wherein the at least one seal surface of the applicator cap comprises threads configured to engage with corresponding grooves of the container.

13 . The device of claim 8 , wherein the applicator cap comprises at least one seal surface, and
wherein the at least one seal surface of the applicator cap is configured to fluidically seal against the container.

14 . The device of claim 1 , wherein the applicator cap comprises polypropylene.

15 . The device of claim 1 , wherein the applicator cap and the container are made of a uniform material.

16 . The device of claim 1 , wherein the at least one lever surface is configured to rotate the applicator cap about an edge of the container.

17 . The device of claim 1 , wherein the handle portion comprises a curved first surface, and a curved second surface opposite and spaced apart from the first curved surface, one of the first and second curved surfaces defining a finger receiver.

18 . The device of claim 16 , wherein the applicator cap further comprises a dimple extending away from the handle portion.

19 . The device of claim 1 , wherein the at least one lever surface is a rotational lever configured to rotate the applicator cap about a central axis of the container in a first direction.

20 . The device of claim 1 , wherein the handle portion comprises a helical first surface and a helical second surface opposite and spaced apart from the helical first surface.

21 . The device of claim 1 , wherein the container further comprises a handle portion having a first end, a second end, and a body that extends between the first end and the second end, wherein the body comprises at least one lever surface;
wherein the at least one lever surface is a rotational lever configured to rotate the container about a central axis of the applicator cap in a second direction opposite of the first direction.

22 . The device of claim 21 , wherein the handle portion of the container comprises a helical first surface and a helical second surface opposite and spaced apart from the helical first surface.

23 . The device of claim 21 , wherein the handle portion of the applicator cap, and the handle portion of the container, are each configured to provide rotational forces opposite each other.

24 . The device of claim 1 , wherein the container comprises a concave surface that defines the reservoir.

25 . A method of applying a contact lens to a wearer's eye the contact lens stored in a package comprising an applicator cap comprising a handle portion having a first end, a second end, and a body that extends between the first end and the second end, wherein the body comprises at least one lever surface; and a container having a reservoir configured to house a contact lens and packaging solution, wherein the at least one lever surface is configured to provide at least one leverage point for movement of the applicator cap relative to the container, and wherein the second end is configured to form a seal against a convex surface of the contact lens, the method comprising:
rotating the handle portion with the leverage point; breaking the seal between the convex surface of the contact lens and the second end of the applicator cap; removing a contact lens from the convex surface; and applying the contact lens to the wearer's eye.

26 . The method of claim 25 , wherein rotating the handle portion further comprises rotating the handle portion about an edge of the container.

27 . The method of claim 25 , wherein rotating the handle portion further comprises rotating the handle portion about a central axis of the container.

28 . A method of packaging a contact lens, comprising:
providing packaging solution in a container; providing a cap with a convex surface that is sealable with the container; providing a contact lens in a convex up orientation in the convex surface forming a seal; and sealing the container by pressing the lid to the container.
