ABSTRACT:
FIELD OF THE INVENTION
This invention relates generally to painting equipment and, more specifically, to paint retaining containers.
BACKGROUND OF TIE INVENTION
Paint retainer containers have always been necessary to retain a quantity of paint for the ready access of the person doing the painting.
A fundamental problem with respect to all paint retaining containers is that they are generally open to the atmosphere. This allows a significant quantity of volatile hydrocarbon materials within the paint to evaporate into the atmosphere. This is a problem for the painter in that it tends to dry out the paint. It is also a problem for the atmosphere because the evaporated hydrocarbons tend to pollute the air.
Numerous attempts have been made to produce a practical paint retaining container which minimizes the exposure of the paint to the atmosphere. None of these attempts, however, have been wholly successful.
Accordingly, there is a need for a paint retaining container which is simple and inexpensive to manufacture and distribute, while at the same time, being practical and efficient for the user.
SUMMARY
The invention satisfies this need. The invention is a paint tray liner comprising (a) a liner body having a forward end, a rearward end, a bottom wall and side walls, the bottom wall of said liner body being a sloped platform having a raised portion at the forward end of the liner body, and depressed paint well portion at the rearward end of the liner body, the side walls defining a perimeter around the paint tray liner; (b) an outer liner flange located around the perimeter of the liner body; and (c) a cover connector attached to the paint tray liner for connecting a paint tray cover to the paint tray liner. The paint tray liner is typically used in combination with a paint tray cover.
The present paint tray liner may be a one-piece construction or a two-piece construction, depending upon whether the cover is removable, or is attached or affixed to the tray. The paint tray liner invention may accommodate a standard size paint brush, paint roller, or other painting tools, and the cover of the paint tray liner may be closed by the user with the brush, roller, and other tools within said liner. The paint tray liner invention may accommodate standard size painting tools out of the paint tray liner's paint well with the paint tray liner's cover in the closed position.
A primary application of this invention is to offer the manufacturer a paint tray liner which is lightweight, yet strong, and inexpensive to manufacture, stackable when stockpiled in the open position.
Another primary application of this invention is to offer the user a paint tray liner which is inexpensive and therefore disposable, and which may have an attached or unattached liner cover, and that said cover may also close over the liner body, when painting tools are housed within the liner body.
The invention is related to applicant's U.S. Pat. No. 5,645,164, the entirety of which is incorporated herein by this reference.
