Description:
FIELD OF THE INVENTION 
     The present invention relates to universal paint grids for distributing paint on paint rollers and, more particularly, to a universal paint grid which can be used either with a paint container having an external cover ledge or an internal cover ledge. 
     BACKGROUND OF THE INVENTION 
     Today paint rollers are being used more and more to apply paint to surfaces. Oftentimes, small paint rollers are dunked directly into the cylindrical paint container. To roll off excess paint, a paint distribution plate or paint grid is inserted into the paint container. 
     Briefly, a paint grid comprises a porous plate which is held in the container so that the user can roll the paint roller on the paint grid to remove excess paint from the roller. One of the problems is that paint containers, and particularly gallon containers, have different shapes which preclude the paint grids from being used with all containers, that is, plastic containers typically have an external ledge, while metal containers usually have an internal ledge, and since the paint grid must be held in the paint container, a paint grid which is usable with a container having an internal ledge is not generally usable with a container having an external ledge. 
     The present invention provides a universal paint grid which is usable with paint containers having either internal or external ledges. 
     DESCRIPTION OF THE PRIOR ART 
     U.S. Pat. No. 4,145,789 shows a paint distribution plate for inserting into an open mouth paint bucket with an external ledge. The paint distribution plate includes opposed flanges 32 which have notches therein which fit over the edge of the paint bucket. To hold the distribution plate in the paint bucket, he provides a resilient, U-shaped insert along the interior of his notch. The patent contends that the distribution plate is locked in the paint bucket by the coaction of the side edges of the distribution plate and the arcuate side walls of the paint bucket in conjunction with the lower edge of the distribution plate and the bottom of the paint bucket. It appears that the tight-fitting relationship between the plate and the interior of the paint bucket is primarily used for holding the distribution plate within the paint container. 
     U.S. Pat. No. 2,669,965 shows a flexible woven material such as terrycloth which is immersed in the paint and then pulled up to allow the user to roll the paint roller over the terrycloth. 
     U.S. Pat. No. 4,083,466 shows a a paint container extension with a mesh-like grid having hooks which are fixed over the lip of the paint container extension. 
     U.S. Pat. No. 4,200,949 shows a paint container and a device for wiping excess paint off the paint roller by squeezing on opposite sides of the roller. 
     U.S. Pat. No. 2,723,410 shows an adjustable paint roller feeder which permits adjustment of the depth of the paint roller shield into the paint container. 
     U.S. Pat. No. 2,988,767 shows a paint bucket with side ribs to permit the user to roll excess paint off the paint roller.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     FIG. 1 reference numeral 10 generally identifies the universal paint grid of the present invention. Paint grid 10 includes a grid member 11 comprised of a substantially planar member 11 having a plurality of regularly spaced rectangular openings 12 therein. Grid member 11 has a straight bottom edge 13 for engaging or placing on the bottom of a paint container, and a top edge edge 14 which is integrally connected to a flexible panel 20. Grid member 11 includes a first top lip 14a on one side of grid member 11 and a second top lip 14b on the opposite side of grid member 11. Connected centrally to edge 14 of grid member 11 is flexible panel 20 which includes a first hooked-shaped ear 23 having an internal lip 34 and a lower lip 22 having a reinforcing strip 22a thereon. Ear 23 forms a rectangular shaped opening 21 for encompassing either an internal or external annular ledge on a paint container. The outside of ear 23 forms a guide edge 28 for directing the ear over an external annular ledge on a paint container. 
     Similarly, located on the opposite side of panel 20 is a second hook-shaped ear 24 having an internal lip 33 and a lower lip 26 having a reinforcing strip 26a thereon. Ear 24 similarly forms a rectangular shaped opening 25 for encompassing either an internal or external annular ledge on a paint container. Also, the outside of ear 24 forms a guide edge 27 for directing ear 24 over an external annular ledge of a paint container. 
     Located in flexible panel 20 is a first rim notch 31 and a second rim notch 32 which fit over the edge of a container to partially engage the top edge of the container. 
     The opening 21 has a height designated by h and a width designated by w 2 . The height and width are selected so as to have the opening sufficiently large so that it encompasses the ledge and the top portion of a paint container with either an internal or an external ledge. When paint grid 20 is not in use, the universal paint grid may be hung by placing opening 38 on a nail or the like. A reinforcing member 39 extends around the top portion for reinforcing the top portion of flexible panel 20. The width of the panel is designated by w 1 . Panel 20 projects out beyond grid member 11 which is sufficiently narrow to fit into a paint container. 
     FIG. 2 shows a side view of paint grid member 11 indicating grid member 11 has a thickness t 1 , and flexible panel 20 has a thickness t 2  which is substantially less than the thickness of t 1  of grid member 11. 
     One of the features of the present invention is that grid member 11 is made from a flexible but resilient material such as polypropylene; however, grid member 11 is made substantially thick so as to have a certain amount of stiffness and rigidity so that it provides sufficient support so that one can roll a paint roller over grid member 11 to remove excess paint from the roller. In contrast, flexible panel 20, while made of the same material, is thinner than grid member 11 so as to have sufficient flexibility to permit engaging of ears 23 and 24 to the top portion of a paint container. 
     FIG. 3 shows a cross-sectional view which illustrates universal paint grid 10 mounted on the external ledge of a plastic paint container. Reference numeral 50 identifies a paint container which may be a gallon plastic bucket on the like. Paint container 50 has an external cylindrical surface 54 with an external annular ledge 51 having an annular underside 51a. The annular top edge of container 50 is identified by reference numeral 52. To illustrate the use of universal paint grid 10 with a paint roller, a paint roller applicator 40 is shown positioned therein with paint roller applicator 40 having a handle 41, a paint roller frame 43 and a roller 42 for rolling on grid member 11, so that any excess paint can fall back into paint 9 located at the bottom of container 50. 
     FIG. 3 also illustrates that grid member 11 is sufficiently rigid so that it provides support to roll roller 42 thereon. As can be observed in FIG. 3, lip 22 of ear 23 hooks on the annular underside 51a of external annular ledge 51 to hold one side of paint grid 10 onto container 50. 
     FIG. 4 shows a front view of container 50 of FIG. 3 illustrating that the opposite ear 24, while shown in phantom, coacts with ear 23 to hold paint grid 10 onto annular lip 51. The recesses 31 and 32 are shown extending around top edge 52 of container 50. As can be envisioned from FIGS. 3 and 4, paint grid 10 is held at an acute angle with respect to the bottom through the use of ears 23 and 24 which engage lip 51 to hold the upper portion of paint grid 10 in position and by edge 13 which rests on the bottom of container 50. 
     FIG. 5 shows the universal paint grid 10 in use with a metal paint container which has an internal annular ledge rather than an external annular ledge as shown in the paint container of FIGS. 3 and 4. Universal paint grid 10 lip 14a fits under internal annular ledge 61 and lip 14b also fits under internal annular ledge 61 to hold paint grid 20 in position in container 60. That is, the width of paint grid 10 is such that the lips 14a and 14b on the top edge of paint grid 10 coact with the underside of internal annular ledge 61. Since flexible panel 20 is more deformable than grid member 11, ears 22 and 27 can be flexed around the external annular ledge of the container to hold the grid in place. 
     FIG. 6 illustrates how ear 23 can flex sufficiently to a nonplanar position to accommodate the positioning of grid member 11 when there is no external annular ledge. 
     FIG. 7 shows a further alternate use of the universal grid 10. In the embodiment, universal paint grid 10 has been flexed by placing flexible panel 20 and by folding ears 23 and 24 to fit inside container 60. The flexibility of panel 20 and ears 23 and 24 permits panel 20 to conform to the interior cylindrical shape of the container while still allowing the grid to maintain its substantially planar shape. This mounting is useful if a person wants to store the universal paint grid in the paint container between painting jobs. 
     FIG. 7 illustrates the side view of grid 10 positioned with bottom edge 13 engaging the internal cylindrical surface 64 of container 60 with the top of panel 20 engaging the underside of internal annular ledge 61. Thus, it can be seen that paint grid 10 is held in position as shown in FIGS. 7 and 8 through the internal annular ledge on container 60. Thus, a feature of the invention is that the grid should have sufficient length so that when placed completely within the container, there is a small amount of flexing to hold grid member 11 in position under internal annular ledge 61. 
     FIG. 8 illustrates a prior art grid 80 having grid member 81 with rectangular shaped openings 82 therein and a handle 83 on the top, for engaging the underside of the lip of a container. The grid shown in FIG. 8 is not usable with the containers having external annular ledges since there is nothing for member 83 to abut against.
