Abstract

A dispenser assembly includes a dispenser bottle having a nipple for dispensing a solution (e.g., eye drop solution, eye wash solution, eye lid cleaner and/or wash solution), and a cap removably couplable to the dispenser bottle over the nipple. An eye cup is fixedly coupled to the dispenser bottle around the nipple. The eye cup can be supported on or rest on the periphery of the eye socket to facilitate delivery of the solution onto or over a user's eye.

Claims (49)

1. A dispenser assembly, comprising:

a dispenser bottle and a nipple via which a solution is dispensed, the nipple projecting from a surface of the dispenser bottle;

a cap removably couplable over the nipple to a shoulder of the dispenser bottle which circumscribes the surface, the cap comprising:

an outer cap;

an inner cap extending within the outer cap; and

a seal at or proximal an end of the inner cap; and

an eye cup fixedly coupled to the surface of the dispenser bottle and configured to fit within the cap when the cap is coupled to the dispenser bottle, the eye cup comprising:

a circumferential wall disposed around the nipple; and

a distal edge of the circumferential wall defining an oval shape, the distal edge configured to be disposed over an eye socket to facilitate delivery of a solution into a user's eye, wherein the nipple is disposed between the distal edge of the circumferential wall and the surface, and wherein the circumferential wall tapers continuously outward from the surface to the distal edge,

wherein when the cap is coupled to the dispenser bottle, the seal sits adjacent the nipple to inhibit leakage of solution from the nipple and

wherein the eye cup fits within the outer cap when the cap is coupled to the dispenser bottle.

2. The dispenser assembly of claim 1 , wherein the nipple extends within the outer cap when the cap is coupled to the dispenser bottle.

3. The dispenser assembly of claim 1 , wherein the seal is one piece with the inner cap and comprises rubber or plastic.

4. The dispenser assembly of claim 1 , wherein the dispenser assembly is configured to prevent contamination of the nipple and prevent inadvertent contact of the nipple with a user's eye.

5. The dispenser assembly of claim 1 , wherein the distal edge of the eye cup is contoured to fit around a periorbital region.

6. The dispenser assembly of claim 1 , wherein a central axis of the eye cup is aligned with a central axis of the dispenser bottle.

7. The dispenser assembly of claim 1 , wherein a height of the nipple above the dispenser bottle is less than half a height of the distal edge of the eye cup above the dispenser bottle.

8. The dispenser assembly of claim 1 , wherein the cap is couplable to the shoulder with an annular snap fit.

9. A dispenser assembly, comprising:

a dispenser bottle and a nipple via which a solution is dispensed, the nipple projecting from a surface of the dispenser bottle;

a cap removably couplable over the nipple to the surface, the cap comprising:

an outer cap;

an inner cap extending within the outer cap; and

a seal at or proximal an end of the inner cap; and

an eye cup fixedly coupled to the surface of the dispenser bottle and configured to fit within the cap when the cap is coupled to the dispenser bottle, the eye cup comprising:

a circumferential wall disposed around the nipple; and

a distal edge of the circumferential wall defining an oval shape, the distal edge configured to be disposed over an eye socket to facilitate delivery of a solution into a user's eye, wherein the nipple is disposed between the distal edge of the circumferential wall and the surface, and wherein the circumferential wall tapers continuously outward from the surface to the distal edge,

wherein when the cap is coupled to the dispenser bottle, the seal sits adjacent the nipple to inhibit leakage of solution from the nipple and

wherein the eye cup fits within the outer cap when the cap is coupled to the dispenser bottle.

10. The dispenser assembly of claim 9 , wherein the eye cup is configured to inhibit the nipple from touching the user's eye.

11. The dispenser assembly of claim 9 , wherein the dispenser bottle is formed from a resilient material.

12. The dispenser assembly of claim 9 , wherein a distal portion of the inner cap extends past the seal, the distal portion of the inner cap configured to encircle the nipple when the cap is coupled to the dispenser bottle.

13. The dispenser assembly of claim 9 , wherein a distal portion of the inner cap is couplable to the nipple.

14. A dispenser assembly, comprising:

a dispenser bottle and a nipple via which a solution is dispensed, the nipple projecting from a surface of the dispenser bottle;

a cap removably couplable over the nipple to the surface, the cap comprising:

an outer cap;

an inner cap extending within the outer cap; and

a seal at or proximal an end of the inner cap; and

an eye cup fixedly coupled to the surface of the dispenser bottle and configured to fit within the cap when the cap is coupled to the dispenser bottle, the eye cup comprising:

a circumferential wall disposed around the nipple; and

a distal edge of the circumferential wall defining an oval shape, the distal edge configured to be disposed over an eye socket to facilitate delivery of a solution into a user's eye, wherein the nipple is disposed between the distal edge of the circumferential wall and the surface, and wherein the circumferential wall tapers continuously outward from the surface to the distal edge,

wherein when the cap is coupled to the dispenser bottle, the seal sits adjacent the nipple to inhibit leakage of solution from the nipple.

15. The dispenser assembly of claim 14 , wherein the eye cup is configured to inhibit the nipple from touching the user's eye.

16. The dispenser assembly of claim 14 , wherein a height of the nipple above the surface is less than half a height of the distal edge of the eye cup above the surface.

17. The dispenser assembly of claim 14 , wherein the dispenser bottle has a flat base surface.

18. The dispenser assembly of claim 14 , wherein a distal portion of the inner cap is couplable to the nipple.

19. The dispenser assembly of claim 14 , wherein a central axis of the eye cup is aligned with a central axis of the dispenser bottle.

20. The dispenser assembly of claim 14 , wherein the nipple extends within the outer cap when the cap is coupled to the dispenser bottle.
