Abstract

Disclosed are various embodiments for a universal sink stopper and strainer. Various embodiments can include a handle, a plate, and a gasket. The gasket can include a first plurality of holes. The plate can include a protrusion and a second plurality of holes. The protrusion is shaped to extend through a portion of the gasket. The handle is configured to rotate to adjust an alignment of the first plurality of holes of the gasket with respect to the second plurality of holes of the plate.

First claim

Therefore, the following is claimed:

1. A sink stopper, comprising:
a gasket comprising a first plurality of holes;
a plate comprising a protrusion and a second plurality of holes, wherein the protrusion is shaped to extend through a portion of the gasket;
a rotatable handle that, when rotated, adjusts an alignment of the first plurality of holes of the gasket with respect to the second plurality of holes of the plate, wherein the rotatable handle is configured to engage with the protrusion of the plate; and
a container attached to a bottom surface of the plate.

2. The sink stopper of claim 1 , wherein the container comprises a first portion that attaches to a second portion, wherein the first portion is attached to the plate.

3. The sink stopper of claim 2 , wherein the bottom surface of the plate further comprises a fastener that extends away from the bottom surface of the plate, and the fastener attaches to a notch along a perimeter of the first portion of the container.

4. The sink stopper of claim 3 , wherein the fastener of the plate is positioned between two of the second plurality of holes on the plate.

5. The sink stopper of claim 1 , further comprising a biocide placed within the container.

6. The sink stopper of claim 1 , wherein the gasket comprises an aperture surrounded by the first plurality of holes, and the aperture comprises an outside edge and an inside edge.

7. The sink stopper of claim 6 , wherein a shape of the protrusion of the plate corresponds to the outside edge and the inside edge of the gasket.

8. The sink stopper of claim 1 , wherein the rotatable handle further comprises a prong extending from a base of the rotatable handle.

9. The sink stopper of claim 8 , wherein the plate further comprises a notch in the protrusion of the plate, wherein the notch is configured to receive the prong from the rotatable handle.

10. The sink stopper of claim 1 , wherein a bottom surface of the gasket comprises a base rim that forms a cavity for receiving the plate.

11. An apparatus, comprising:
a gasket comprising a first plurality of holes;
a plate comprising a protrusion and a second plurality of holes, wherein the protrusion is shaped to extend through a portion of the gasket; and
a rotatable handle that, when rotated, adjusts an alignment of the first plurality of holes of the gasket with respect to the second plurality of holes, wherein the rotatable handle comprises an inner cavity is configured to engage with the protrusion of the plate.

12. The apparatus of claim 11 , further comprising: a container attached to a bottom surface of the plate, wherein the container comprises a first portion and a second portion.

13. The apparatus of claim 12 , wherein the bottom surface of the plate further comprises a fastener that extends away from the bottom surface of the plate, and the fastener attaches to a notch along a perimeter of the first portion of the container.

14. The apparatus of claim 11 , wherein the rotatable handle further comprises a prong extending from a base of the rotatable handle.

15. The apparatus of claim 14 , wherein the protrusion further comprises a notch that is configured to receive the prong from the rotatable handle.

16. The apparatus of claim 15 , wherein the gasket comprises an aperture, and the aperture comprises an outside edge and an inside edge.

17. The apparatus of claim 12 , further comprising a biological agent placed within the container.

18. The apparatus of claim 11 , wherein a bottom surface of the gasket comprises a base rim that forms a cavity for receiving the plate.

19. The apparatus of claim 11 , wherein a shape of the protrusion of the plate corresponds to a perimeter formed by an outside edge and an inside edge of a center aperture of the gasket.

20. The apparatus of claim 11 , wherein the gasket further comprises:
a flexible skirt expanding from an inner diameter to an outer diameter; and
a first rim extending along an external, lateral surface of the gasket.
