Abstract

A drain cover includes a base portion including an outer rim and defining a collection area. The drain cover also includes a central portion coupled to the base portion and extending upward from the base portion, wherein the collection area tapers from the central portion toward the outer rim, and wherein the collection area is vertically lower adjacent the central portion relative to an outer periphery of the collection area.

First claim

The invention claimed is:

1. A drain cover comprising:
a base portion including an outer rim and defining a collection area; and
a central portion including a wall extending upward from the base portion,
wherein the collection area continuously tapers from the wall toward the outer rim relative to a horizontal plane extending through opposite sides of the outer rim, and
wherein an upper surface of the collection area is vertically lower adjacent the central portion relative to an outer periphery of the collection area.

2. The drain cover of claim 1 , wherein the base portion is elongated along a longitudinal axis that defines the horizontal plane, and wherein the base portion includes openings oriented across the longitudinal axis.

3. The drain cover of claim 1 , wherein the base portion is elongated along a longitudinal axis defining the horizontal plane, and wherein the collection area is deeper adjacent the central portion than adjacent the outer rim.

4. The drain cover of claim 1 , wherein the wall at least partially defines a column that has openings and that defines a cavity, and wherein the openings permit passage of water through the column into the cavity.

5. The drain cover of claim 4 , wherein the openings are elongated in a vertical direction.

6. The drain cover of claim 4 , wherein the central portion includes a top wall enclosing a top of the column.

7. The drain cover of claim 6 , further comprising a rib disposed in the cavity and attached to one or both of the column and the top wall.

8. The drain cover of claim 7 , wherein the rib divides the cavity into separate areas, and wherein there is no fluid communication between the separate areas through the rib.

9. The drain cover of claim 7 , further comprising another rib extending between the central portion and the outer rim.

10. A drain cover comprising:
a base portion defining a collection area; and
a central portion coupled to the base portion and extending upward from the base portion, the central portion including a column having a top wall and a rib extending from the top wall and including a projection that extends below a lowermost part of the base portion, the projection configured to engage a drain hole to limit rotation of the drain cover relative to the drain hole,
wherein the collection area is oriented to direct water and debris toward the central portion.

11. The drain cover of claim 10 , wherein the base portion is elongated along a longitudinal axis that defines a horizontal plane, and wherein the base portion includes openings oriented across the longitudinal axis.

12. The drain cover of claim 10 , wherein the base portion is elongated along a longitudinal axis that defines a horizontal plane, and wherein the collection area is deeper adjacent the central portion than adjacent the outer rim.

13. The drain cover of claim 10 , wherein the central portion is defined by a column that has openings and that defines a cavity, and wherein the openings permit passage of water through the column into the cavity.

14. The drain cover of claim 13 , wherein the openings are elongated in a vertical direction.

15. The drain cover of claim 10 , further comprising a second rib extending from the central portion to an outer rim of the base.

16. A merchandiser comprising:
a base supporting a product display area and including a drain hole;
a drain cover coupled to the base over the drain hole and including a raised central portion and a base portion, the drain cover defining a collection area adjacent the central portion,
wherein the drain cover is spaced from a surface of the base by a spacer such that water can flow from the collection area through the drain cover and along the surface toward the drain hole.

17. The merchandiser of claim 16 , wherein the spacer is disposed on a lower surface of the base portion and in contact with a surface of the base to separate the base portion from the surface of the base.

18. The merchandiser of claim 17 , wherein the base portion includes an outer rim and is elongated along a horizontal plane that extends through opposite sides of the outer rim, and wherein the lower surface of the base portion and the surface of the base extend at a downward angle relative to the horizontal plane.

19. The merchandiser of claim 16 , wherein the drain cover further includes a projection extending into the drain hole to limit rotation of the drain cover relative to the drain hole.
