Abstract

Urinal screens are provided including an outer ring and a web portion bounded by the outer ring and formed from a plurality of web strings disposed in a mesh pattern, such that a plurality of open areas are defined among the web strings. The web portion includes a vaulted portion. Urinal screen assemblies are also provided and include a urinal screen and a bioenzymatic block containing odor combatting chemistry disposed in a void formed by the vaulted portion of the urinal screen.

Claims

1. A urinal screen, comprising:

an outer ring;

a web portion bounded by the outer ring and having a first face and an opposed second face, the web portion comprising a plurality of web strings disposed in a mesh pattern, such that a plurality of open areas are defined among the web strings; and

a plurality of posts projecting from the first face of the web portion,

wherein the web portion comprises a planar portion and a vaulted portion, with the planar portion extending from the outer ring and surrounding the vaulted portion.

2. The urinal screen of claim 1, wherein the planar portion and the vaulted portion are integrally formed.

3. The urinal screen of claim 1, wherein the vaulted portion comprises a hemisphere, a frustocone, or a cylinder.

4. The urinal screen of claim 1, wherein portions of the web strings forming the first face of the web portion are substantially rounded in profile.

5. The urinal screen of claim 1, wherein the open areas of the web portion have a major dimension of from about 1 mm to about 30 mm in plan view.

6. The urinal screen of claim 1, wherein each of the plurality of posts comprises a substantially rounded tip and a substantially rounded profile.

7. The urinal screen of claim 1, wherein each of the plurality of posts has a height of from about 0.5 mm to 1 cm.

8. The urinal screen of claim 1, wherein the plurality of web strings comprise a first set of the web strings that are substantially parallel to one another and a second set of the web strings that are substantially parallel to one another and are substantially perpendicular to the first set of web strings.

9. The urinal screen of claim 1, wherein the second face comprises an elevational feature configured to elevate at least a portion of the web portion off of a urinal floor, the elevational feature comprising a plurality of posts or ribs projecting from and/or integral with the second face of the web portion.

10. A urinal screen assembly, comprising:

the urinal screen of claim 1; and

a bioenzymatic block containing odor combatting chemistry disposed in a void formed by the vaulted portion.

11. The urinal screen assembly of claim 10, further comprising a plurality of spacer nubs projecting from an inner surface of the vaulted portion, wherein the spacer nubs are effective to space the bioenzymatic block from the web portion.

12. The urinal screen assembly of claim 10, further comprising a cover surrounding the bioenzymatic block.

13. The urinal screen assembly of claim 12, wherein the cover comprises a waterproof upper surface and a base comprising at least one aperture to permit liquid to contact the bioenzymatic block and thereby release the odor combatting chemistry.

14. A urinal screen, comprising:

an outer ring; and

a web portion bounded by the outer ring and having a first face and an opposed second face, the web portion comprising a plurality of web strings disposed in a mesh pattern, such that a plurality of open areas are defined between the web strings,

wherein the web portion comprises a vaulted portion defining a concave inner surface,

wherein a plurality of spacer nubs project from the concave inner surface of the vaulted portion.

15. The urinal screen of claim 14, wherein the web portion comprises a planar portion and a vaulted portion, with the planar portion extending from the outer ring and surrounding the vaulted portion.

16. The urinal screen of claim 15, wherein the planar portion and the vaulted portion are integrally formed.

17. The urinal screen of claim 14, wherein the vaulted portion comprises a hemisphere, a frustocone, or a cylinder.

18. The urinal screen of claim 14, wherein portions of the web strings forming the first face of the web portion are substantially rounded in profile.

19. The urinal screen of claim 14, wherein the plurality of web strings comprise a first set of the web strings that are substantially parallel to one another and a second set of the web strings that are substantially parallel to one another and are substantially perpendicular to the first set of web strings.

20. The urinal screen of claim 14, wherein the second face comprises an elevational feature configured to elevate at least a portion of the web portion off of a urinal floor, the elevational feature comprising a plurality of posts or ribs projecting from or integral with the second face of the web portion.

21. The urinal screen of claim 14, wherein each of the spacer nubs has a height of from about 1 mm to about 1 cm.

22. A urinal screen assembly, comprising:

the urinal screen of claim 14; and

a bioenzymatic block containing odor combatting chemistry disposed in a void formed by the vaulted portion.

23. The urinal screen assembly of claim 22, wherein the spacer nubs are effective to space the bioenzymatic block from the web portion.
