Abstract

An eye drop applicator includes a main body with a lower portion and an upper portion having a cavity configured to retain a predetermined amount of medication. The lower portion may include an opening configured to snuggly receive a user'"'"'s finger and/or a top of a medication bottle. The eye drop applicator may also include a removable cap configured to attach to the upper portion of the main body to cover the cavity.

Claims

1. An eye drop applicator comprising:

a main body comprising;

(1) a lower portion with an opening configured to receive a user'"'"'s finger, wherein the opening comprises a variable diameter that changes along a height of the main body; and

(2) an upper portion, wherein the upper portion comprises a cavity configured to retain a predetermined amount of liquid medication; and

wherein a majority of a bottom surface of the cavity comprises a continuous flat surface.

2. The eye drop applicator of claim 1, wherein the liquid medication is eye medication.

3. The eye drop applicator of claim 1, wherein the predetermined amount is approximately 1-2 drops.

4. The eye drop applicator of claim 1, wherein the cavity is configured to retain the liquid medication using surface tension.

5. The eye drop applicator of claim 1, wherein the opening comprises a maximum diameter adjacent a lower edge of the main body.

6. The eye drop applicator of claim 1, wherein the opening comprises a first portion with a constant diameter along a section of the height of the main body such that an inner surface of the opening forms a cylindrical shape along the first portion.

7. The eye drop applicator of claim 1, wherein the opening comprises a fourth portion with a decreasing diameter along a section of the height of the main body such that an inner surface of the opening curves and forms a concave shape along the fourth portion.

8. The eye drop applicator of claim 1, wherein the opening comprises a third portion with a linearly decreasing diameter along a section of the height of the main body such that an inner surface of the opening includes a straight taper along the third portion.

9. The eye drop applicator of claim 1, wherein the opening comprises a second portion with a decreasing diameter along a section of the height of the main body such that an inner surface of the opening curves and forms a convex shape along the second portion.

10. The eye drop applicator of claim 8, further comprising a fifth portion comprising a linearly decreasing diameter.

11. The eye drop applicator of claim 1, wherein the opening comprises a top portion that is dome shaped.

12. The eye drop applicator of claim 1, further comprising a removable and replaceable cap configured to cover the cavity, wherein the main body comprises an engagement member configured to engage with one or more features of the removable and replaceable cap to secure the removable and replaceable cap.

13. The eye drop applicator of claim 12, wherein the engagement member comprises an annular protrusion and the one or more features comprises a channel.

22. The eye drop applicator of claim 1, wherein the main body comprises a rim disposed at a perimeter of the cavity such that the rim extends in a direction that is approximately perpendicular to the flat surface.

23. The eye drop applicator of claim 1, wherein the opening comprises:

a first portion with a constant diameter along a section of the height of the main body such that an inner surface of the opening forms a cylindrical shape along the first portion;

a second curved portion with a decreasing diameter along a section of the height of the main body such that the inner surface of the opening curves and forms a concave shape along the second curved portion; and

a third portion with a linearly decreasing diameter along a section of the height of the main body such that the inner surface of the opening includes a straight taper along the third portion.

24. The eye drop applicator of claim 23, wherein the inner surface of the opening transitions directly from the first portion to the second curved portion and from the second curved portion to the third portion.

14. An eye drop applicator comprising:

a main body comprising a cavity configured to retain a predetermined amount of medication and an opening configured to receive a user'"'"'s finger;

wherein;

the cavity comprises a continuous flat surface that is recessed relative to an uppermost portion of the main body; and

the opening comprises a diameter that decreases along a height of the main body toward a top of the main body.

15. The eye drop applicator of claim 14, wherein the cavity is configured to retain the medication using surface tension.

16. The eye drop applicator of claim 14, wherein the opening comprises a maximum diameter adjacent a lower edge of the main body.

17. The eye drop applicator of claim 14, wherein the opening comprises a first portion with a constant diameter along a section of the height of the main body such that an inner surface of the opening forms a cylindrical shape along the first portion.

18. The eye drop applicator of claim 14, wherein the opening comprises a third portion with a linearly decreasing diameter along a section of the height of the main body such that an inner surface of the opening includes a straight taper along the third portion.

19. The eye drop applicator of claim 14, wherein the opening comprises a second portion with a decreasing diameter along a section of the height of the main body such that an inner surface of the opening curves and forms a convex shape along the second portion.

20. The eye drop applicator of claim 14, further comprising a removable and replaceable cap configured to cover the cavity, wherein the main body comprises an engagement member that engages with one or more features of the removable cap to secure the removable and replaceable cap.

21. The eye drop applicator of claim 20, wherein the engagement member comprises an annular protrusion and the one or more features comprises a channel.
