DETAILED DESCRIPTION OF THE INVENTIONS
(8) An embodiment of a urinal screen 10 is illustrated in
(9) In some embodiments, the screen 10 has a polygonal, elliptical, circular, or other overall shape. For example, as illustrated in
(10) The frame 14 and/or posts 22 can be constructed from a polymeric or solid material. For example, the frame 14 and/or posts 22 can be constructed using a 3D printer. In some cases, additives are added to the material of the frame 14 and/or posts 22. Additives can include, for example, bacteria and/or odor neutralizers, silver ions, and other additives or combinations of additives. One method of manufacturing an embodiment of the urinal screen 10 can include providing plastic or EVA material, which may have a melting point of not greater than 250 F., loading the plastic or EVA with at least 15% to about 75% by weight of fragrance material to produce a fragranced plastic or EVA, loading the fragrance at a stage conducted at temperatures such that the fragranced plastic or EVA is from at least 15% by weight fragrance upon completion of the loading stage, and molding the fragranced plastic or EVA into a urinal screen, sized and shaped to be disposed in a urinal, forming openings 18 in the frame 14, and forming posts 22 extending from the frame 14.
(11) The openings 18 can have various shapes, including, but not limited to, polygons (e.g., triangles, rectangles, pentagons, hexagons, etc.), ellipses, and/or some combination thereof. In some embodiments, each of the openings 18 has a substantially identical shape. In some embodiments, one or more of the openings 18 has a different shape from one or more of the other openings.
(12) The openings 18 can occupy a large percentage of the overall surface area of the frame 14 as viewed in
(13) A top surface (e.g., the first surface 26) of the frame 14 can lie on a first plane when the urinal screen 10 is set on a flat surface. In some cases, a bottom surface (e.g., the second surface 30) of the frame 14 can lie on a second plane when the urinal screen is set on a flat surface. In some embodiments, a maximum cross-sectional area of the frame 14 (e.g., the area not occupied by openings 18), as measured on a frame plane through the frame and parallel to the first and/or second planes is less than , less than , less than , less than , less than 1/7, less than , less than 1/9, less than 1/10, less than 1/12, less than 1/15, and/or less than 1/20 of the area defined by the outer perimeter of the frame as measured in the plane. Many variations are possible
(14) As illustrated in
(15) In some cases, the sides 42 and/or corners 46 of the openings 18 have contoured (e.g., convex) upper and/or lower surfaces. The contoured surfaces of the sides 42 and corners 46 can deflect fluid (e.g., urine) to reduce splash in the urinal, toilet, or other environment in which the urinal screen 10 is installed.
(16) In some embodiments, as illustrated in
(17) In some embodiments, the posts 22 extend from the corners 46 of the frame forming openings 18.
(18) As illustrated in
(19) In some embodiments, at least half, at least , at least , at least , at least , at least 9/10, at least and/or at least 1/10 of the first plurality of posts 22a have a same size and shape as at least half, at least , at least , at least , at least , at least 9/10, at least and/or at least 1/10 of the second plurality of posts 22b. In some embodiments, one or more of the posts in the first plurality of posts 22a has a different shape and/or height than one or more of the posts in the second plurality of posts 22b. In some embodiments, the first plurality of posts 22a and/or the second plurality of posts 22b have a plurality of heights. For example, a percentage (e.g., 25%, 50%, 75% or some other percentage) of the posts 22 can be shorter than the remaining posts as measured from the first or second surfaces 26, 30 of the frame 14. In some embodiments, at least , at least , at least , and/or at least of the posts 22 have a height differing from the remaining posts 22. In some embodiments, one or more of the posts 22 is at least , at least 1/10, at least , at least , and/or at least shorter than one or more of the other posts 22. In some cases, each post is at least shorter, at least 1/10 shorter, at least shorter, at least shorter, at least shorter, at least taller, at least taller, at least taller, at least 1/10 taller, and/or at least 1/16 taller than at least one of the 3 closest posts 22, at least one of the 5 closest posts 22, at least one of the 7 closest posts 22, at least one of the 9 closest posts 22, at least one of the 10 closest posts 22, at least one of the 12 closest posts 22, and/or at least one of the 15 closest posts 22. In some embodiments, shortening a percentage of the posts 22 can reduce the likelihood that debris is caught in the urinal screen 10. The posts 22 can extend perpendicularly from the frame 14 (e.g., from the first or second surfaces 26, 30 of the frame 14). In some embodiments, one or more of the posts 22 extends from the frame 14 at a non-perpendicular angle (for example, non-perpendicular angle A of
(20) The frame 14 can have a generally planar or flat shape. In some embodiments, the frame 14 is curved or otherwise shaped in non-planar fashion. For example, the frame 14 can be molded in a non-planar shape to match the contours of a urinal or toilet.
(21) The frame 14 can have a frame thickness 34 (e.g., a distance between the first and second surfaces 26, 30 of the frame 14). The frame thickness 34 can be uniform across the entire frame 14 or can vary in certain portions of the frame 14. An overall thickness 38 of the urinal screen 10 can be measured from a tip of the tallest post 22 extending from the first surface 26 of the frame 14 to a tip of the tallest post 22 extending from the second surface 30 of the fame 14 as measured perpendicularly from the first and second surfaces 26, 30. In some cases, wherein the frame 14 is not planar/flat, the overall thickness 38 of the urinal screen 10 can be determined via the tips of the posts 22 as measured perpendicularly to a tangent plane of the first surface 26 of the frame 14 at a point on the frame 14 where the thicknesses 34, 38 are being measured.
(22) In some embodiments, the frame thickness 34 at a given position on the frame 14 is less than or equal to approximately of the overall screen thickness 38 as measured perpendicularly to the first surface 26 of the frame 14 at the given position. In some embodiments, the frame thickness 34 is less than or equal to , less than or equal to , less than or equal to , less than or equal to , less than or equal to , less than or equal to 2/9, less than or equal to , less than or equal to 1/10, less than or equal to 1/16, and/or less than or equal to 1/32 of the overall screen thickness 38. Use of a thin frame 14 can reduce the overall weight of the urinal screen 10.
(23) In some embodiments, the urinal screen 10 is configured such that a plurality of posts 22 space the frame 14 from the installation surface of a urinal or other fixture onto which the urinal screen 10 is installed. The posts 22 space the frame 14 from the installation surface independent from the orientation of the urinal screen 10. For example, the second plurality of posts 22b can form a base of the urinal screen 10 and can space the frame 14 from the installation surface when the screen 10 is installed with the second surface 30 of the frame 14 facing the installation surface. On the other hand, the first plurality of posts 22a can form a base of the urinal screen 10 and can space the frame 14 from the installation surface when the screen 10 is installed with the first surface 26 of the frame facing the installation surface. In some embodiments, the posts 22 space the frame 14 from the installation surface by at least of the overall thickness 38 of the urinal screen 10. In some embodiments, the posts 22 space the frame 14 from the installation surface by at least , at least 1/7, at least , at least , at least , at least , and/or by at least 4/9 of the overall thickness 38 of the urinal screen 10.
(24) Spacing the frame 14 from the installation surface can reduce the likelihood that the openings 18 are clogged by debris. In some embodiments, the posts 22 positioned between the frame 14 and the installation surface can reduce splashing in the urinal by deflecting urine or other fluids which pass between the frame 14 and the installation surface (e.g., fluid that passes through the openings 18 or around the perimeter of the frame 14).
(25) For expository purposes, the term horizontal as used herein is defined as a plane parallel to the plane or surface of the floor of the area in which the system being described is used or the method being described is performed, regardless of its orientation. The term floor floor can be interchanged with the term ground. The term vertical refers to a direction perpendicular to the horizontal as just defined. Terms such as above, below, bottom, top, side, higher, lower, upper, over, and under, are defined with respect to the horizontal plane.
