Abstract
A paint tray cover includes a body having a paint tray receiving cavity. The body includes an outer air impervious layer which extends across the paint tray receiving cavity.
An inner moisture absorbing liner extends across the paint tray receiving cavity. Prior to use, the moisture absorbing liner is exposed to water and absorbs moisture. Air within the paint tray is kept moist by moisture provided by the inner moisture absorbing liner and retained by the outer air impervious layer.
The high humidity slows the rate at which the paint drys.

Description
-TITLE OF THE INVENTION:
paint tray cover NAME OF INVENTOR:
Edmund Jacob Nickel FIELD OF THE INVENTION
The pre~ent invention relates to a paint tray cover.
P~K~ROUND OF THE INVENTION
When a painter takes a break from painting, the paint in his tray, on his roller and on his brush starts to dry. The break is, typically, over a lunch hour or over night. With some types of latex paint this drying is particularly rapid, and sufficient drying can occur over a coffee break to have detrimental effects. When a continuous warm air stream is provided by nature or ventilation, fifteen minutes is more than sufficient time to dry many brands of latex paint. In such conditions, if a paint tray filled with latex paint is left uncovered, a skin or layer starts to form on the surface of the paint. To retard this drying process, paint tray covers are used.
United States Patent 3,406,812 which issued to Henry in 1968 discloses an air impervious bag that is placed around a tray and paint roller. The bag is then sealed to prevent the circulation of air, thereby retarding the drying process.
Although no material is specified, the bag appears to be of polymer plastic.
~185757 -United States Patent 4,541,542 which issued to Florentino in 1985 discloses two further embodiments of paint tray cover.
A first embodiment consists of a flexible semi-rigid polyethylene cover, which provides a snug airtight fit over a paint tray. A second embodiment consists of a cover made from a flexible material which is secured around an edge of a paint tray by an elastic band. Both embodiments have what is described as a "spacial protrusion" to accommodate a handle of a paint brush or roller. The covers are intended to be used when a paint covered brush or roller is to be left overnight is an empty paint tray.
Flexible polymer plastic paint tray covers, have an inherent drawback. In order to place a cover onto and take the cover off of a paint tray, the cover must be flexed. After repeated use, the cover becomes soiled with dried paint.
Flakes of this dried paint fall off the cover and into the paint tray, as the cover is placed on and taken off. In addition, the time duration that a paint tray can be left with a polymer plastic cover i~ severely limited. Even with a polymer plastic cover, paint will dry in a matter of a few days.
SUMMARY OF THE INVENTION
What is required is a paint tray cover that will enable paint to be left in a paint tray for longer periods and which will not shed unwanted flakes of dried paint.
According to one aspect of the present invention there is provided A paint tray cover including a body having a paint tray receiving cavity. The body has an outer air impervious layer extending across the paint tray receiving cavity and an inner moisture absorbing liner extending across the paint tray receiving cavity.
The body can be similar in form to the paint tray cover~
disclosed in the Henry and Florentino references. It is preferred, however, that the paint tray cover be in the form of a frame which defines the paint tray receiving cavity. An outer air impervious layer, preferably of polymer plastic, is secured to the frame and extends across the paint tray receiving cavity. An inner moisture absorbing liner, preferably of cloth, is secured to the frame and extends across the paint tray receiving cavity.
Although beneficial results may be obtained through the use of the paint tray cover, as described above, room is required to accommodate a paint brush or a roller. Even more beneficial results may, therefore, be obtained when an opening is provided along one side of the frame, whereby a handle of either a paint brush or a paint roller is accommodated.
Although beneficial results may be obtained through the use of the paint tray cover, as described above, by merely setting the frame so it overlays the paint tray. In some situations it may be preferred to have the frame secured to the paint tray. Even more beneficial results may, therefore, be obtained when means is provided to secure the frame to a paint tray.
According to another aspect of the invention there is provided a method of preventing paint in a paint tray from drying between uses. Firstly, providing a paint tray cover as described above. Secondly, wetting with water the inner moisture absorbing liner, such that the moisture absorbing liner retains moisture. Thirdly, positioning a paint tray with wet paint within the paint tray receiving cavity. The rate that paint dries is directly related to humidity. Air within the paint tray is kept moist by moisture provided by the inner moisture absorbing liner and retained by the outer air impervious layer.
BRIEF n~RTPTION OF THE DRAWINGS
These and other features of the invention will become more apparent from the following description in which reference is made to the appended drawings, wherein:
FIGURE 1 i8 a perspective view of a paint tray cover made in accordance with the teachings of the present invention.
FIGURE 2 is a side elevation view, in section, of the paint tray cover illustrated in FIGURE 1.
FIGURE 3 is a perspective view of an alternative embodiment of paint tray cover made in accordance with the teachings of the present invention.
DET~TT-~n _ ---PTPTION OF THE l~KK~ EMBODIMENT
The preferred embodiment, a paint tray cover generally identified by reference numeral 10, will now be described with reference to FIGURES 1 through 3.
Referring to FIGURE 2, paint tray cover 10 includes a frame 12 which defines a paint tray receiving cavity 14. An outer air impervious layer of polymer plastic 16 is secured to frame 12 and extends across paint tray receiving cavity 14.
An inner moisture absorbing cloth liner 18 is secured to frame 25 12 and also extends across paint tray receiving cavity 14. An opening 20 is provided along one side 22 of frame 12. Opening 20 can be slotted, as illustrated in FIGURE 1, or can be formed in frame 12, as illustrated in the alternative embodiment of FIGURE 3. Frame 12 will stay in position on a paint tray 26, by virtue of its weight or, optionally, clips 24 may be provided to secure frame 12 to a paint tray 26, as illustrated in FIGURE 2.
The preferred method of use of paint tray cover 10 will now be described with reference to FIGURES 1 through 3. The method includes the following steps. Firstly, providing paint tray cover 10, as described above. Secondly, wetting with -water inner moisture absorbing cloth liner 18, such that cloth liner 18 absorbs and retains moisture. Thirdly, positioning paint tray 26 cont~;n;ng a quantity of paint 28 within paint tray receiving cavity 14. In most cases, there will also be either a paint brush or a paint roller. In FIGURES 1 through 3, a paint roller 30 is illustrated having a handle 32. It is not desirable to leave paint roller 30 immersed in paint 28.
Paint roller 30 is, therefore, pulled toward side 22 of frame 12 with handle 32 of paint roller 30 accommodated by opening 20.
The underlying principle of paint tray cover 10, is that the rate at which paint dries is directly related to humidity.
Air within paint tray 26 is, therefore, kept moist by moisture within cloth liner 18. Polymer plastic layer 16 serves a dual function of ret~;n;ng moisture within paint tray 26 and excluding dry air. If only cloth liner 18 were used, it would dry out rapidly and paint roller 30 would stick to the cloth.
Polymer plastic layer 16 helps slow down the rate at which cloth liner 18 dries. As long as cloth liner 18 remains moist, paint tray cover 10 will function in a manner superior to the previously described prior art paint tray covers. Should cloth liner 18 become soiled by paint, paint will not come off in flakes. If cloth liner 18 becomes so covered in paint that it is no longer absorbent, it should be replaced. Paint tray cover 10 and the described method of use is particularly effective with latex paints, although it also has utility with oil based paints by keeping humidity high to slow the drying process.
It will be apparent to one skilled in the art that modifications may be made to the illustrated embodiment without departing from the spirit and scope of the invention as hereinafter defined in the Claims.
