BACKGROUND OF THE INVENTION

1. Field of the Invention
This invention relates to paint brushes and, more particularly, to a paint brush protective cover that protects the bristles of paint brushes from being damaged during wet or dry storage or nonuse thereby extending the life of the paint brush.
2. Related Art
In cases where a purchaser opts to purchase a paint brush to perform a painting job, there is a choice of brush shape, size and different filament materials. A professional painter can own many brushes, each with its own use. Typically each project can require several brushes, for large areas a 3 or 4 inch is used for general cutting in large pieces or general use whereas and for trim a 1½ inch works well. On a professional site there may be a crew of painters each using several brushes.
Fine paint brushes are expensive however they are required for a professional job as they apply a smoother finish with less brush strokes and paint faster and with less effort. If properly cleaned and stored they will last for years and conversely if not will have a short life. Inexpensive paint brushes can shed bristles into the finish and are difficult to work with, producing an inferior finish.
Paint brushes are categorized according to the type of coating being applied; water based paints and primers, such as latex or acrylic paints and primer plus water based epoxy; oil based paints and primers, such as alkyd paints and primers plus oil based epoxies; solvent thinned paints and primers; water based clear wood finishes and stains, such as acrylic urethane, water based polyurethane and its variants plus water based wood stains; oil based clear wood finishes and stains; this includes the common varnish and polyurethane plus oil based wood stains; all solvent thinned clear finishes and wood stains; shellac primers and clear finishes, such as tinted and clear shellac is thinned with denatured alcohol.
Each of these “types” of coatings or stains has a specific type of brush that is used. Type of paint brush refers to the filaments used in its construction. These filaments can be synthetic, natural, or a combination of the two. Synthetic refers to different types of plastics used to make the filaments, nylon and polyester or blends of the two. Natural refers to animal hair that is used in the brushes construction, this type of filaments are called bristles. Filaments are designed for specific solvents and will be damaged if used in the wrong solvent or improperly stored.
Synthetic brushes loose there shape in oil base paints and primers, an oil paint brush must be stiff enough to hold its shape and soft enough not to leave to many brush marks. Brush manufactures use a blend of different natural bristles to change the softness and stiffness for performing a job, for example, one having the stiffness for cutting in a straight line and thicker hair for holding more paint or one suited for varnishes, polyurethane and stains or one's for clear wood finishes require a very soft brush for the best results.
Bristle brushes cannot be used with latex paints or be cleaned with water this will ruin the brush. Natural bristle paint brushes absorb water and loose their shape, becoming impossible to control. However, cleaning the brush after every use is not desirable as it takes time and use of costly solvents.
It is desirable to leave the brush wet. Some painters leave the brush in a zip lock bag or in a bucket of paint. While this prevents cleanup, it often results in the disfigurement of the bristles. This is particularly problematic with cut-in brushes which come in a variety of shapes such as angular, flat, and oval, and size ranges from 1-6 inches wide and if disfigured become useless.
Fine paint brushes typically are expensive. User's of fine paint brushes, such as professionals, require excellent coverage from their paint brush, durability from their paint brush, greater efficiency in production, precise lines, proven results for smooth finishes and a lack of bristles or filaments left behind from the paint brush. When a paint brush no longer is capable of producing, the paint brush will be discarded and a new paint brush is purchased to replace the old paint brush.
After a job is finished, the brush must be cleaned in an appropriate solution to remove all of the remaining paint. Sometimes the bristles tend to separate and fray off in non-uniform directions and become a problem for the next usage so care must be taken to store the brush in a manner wherein the bristles can be maintained aligned.
Covers that the paint brushes are sold in are made of paper and are rather flimsy and easily tear and do not last very long. If no protective cover is used, in addition to the above described disfigurement occurring, dust and other particles generally stick and become imbedded inside the bristles. These particles will collect on the paint producing non-uniform streaks of paint during use.
Prior attempts to cover paint brushes include conventional paper or plastic covers which substantially fold about the bristles to maintain the filament shape. Some cases provide for air holes so that the filaments can dry after cleaning is performed.
The problem which is not addressed is that of wet media storage. Painters need a simple and easy cover for both dry and wet storage of the brushes which protects the filaments. There is also a need for quick, safe and easy transportation of brushes. Therefore, a need exists to provide an improved paint brush protective cover. While the inventor has improved the art with his prior inventions, there remains a need to improve paint brush covers in a way to preserve their configuration and make them simple to use, allow for wet and dry storage, easy cleanup and durability and be inexpensive.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring now to the drawings, a paint brush protective cover is generally designated by the numeral 10. The paint brush protective cover 10 includes a single jacket 12 made from an anti-stick polymer plastic, such as polystyrene, so that paint will not readily adhere to the jacket 12. This will aid in the wet storage aspect of the invention.
The jacket 12 can be rectangular in shape and it is contemplated that the jacket 12 can be configured with various shapes and sizes so long as the objectives of the invention can be maintained. The jacket 12 should be sufficient size to contain a lower end 13 of the paint brush 14 and at least part of an upper end 15 of the paint brush 14. By way of example, the jacket 12 is configured for a 2″ brush 14.
The jacket 12 has a hollow interior section 16 which is defined by a first panel 18 and a second panel 20 of the jacket 12 which are removably connectable to one another in a manner to be maintained in a predetermined spaced relation. Each panel 18 and 20 has an upper end 22 and 24, respectively, and a lower end 26 and 28, respectively, which are configured to be complementary connected in a manner with the upper ends 22 and 24 adjacent one another and the lower ends 26 and 28 adjacent one another. Each panel 18 and 20 have transverse exterior ribs 21 and 23 respectively which here are shown as rectangular ribs across upper ends 22 and 24 respectively.
The first panel 18 includes lateral connecting surfaces 30A and 30B and can be configured to be received inside of the second panel 20 lateral connecting surfaces 32A and 32B. The end 24 includes a retaining member 25 which together with connecting surfaces 32A and 32B provide a receiving area for connecting surfaces 30A and 30B. By way of example, lateral connecting surfaces 30A and 30B fit within retaining members 25 and surfaces 31A and 31B or other friction fit surface to improve connection with connecting surfaces 32A and 32B. A laterally extending tab 34 can be provided on the first panel 18 to aid in separating the panels 18 and 20 once connected.
The jacket panels 18 and 20 are of a length greater than a combined length of filaments and at least a collar part of the paint brush retaining the filaments and preferably a greater than a combined length of filaments (herein referred to as lower end 13 of the brush 14), and collar part of the paint brush retaining the filaments and part of the handle (herein referred to as upper part 15 of the brush 14).
Upper ends 22 and 24 are configured to retain about the upper part 15 of the brush 14 and lower ends 26 and 26 are configured to retain about lower end 13 of the brush 15. A pair of compressible pads 51A and 51B are provided to aid in such retention. The pads 51A and 51B can have a tacky pressure sensitive material adhered to a surface thereof and the pad can be made of compressible open cell foam, for example and thus can be attached to 18 and 20, respectively. Thus, the pads 51A and 51B can be used to retain the collar of the paint brush 14. In this way, the brush 14 can be adequately held in place so that the brush 14 does not slip to a point where bristles/filaments touch the end panel 50 which can result in deformation of the filaments. Each panel 18 and 20 can include a plurality of laterally spaced elongated openings 36 and 38, respectively, which extend from respective upper ends 22 and 24, respectively, and into the lower ends 26 and 28, respectively, terminating at a predetermined distance “X” short of an edge 40 and 42 of each panel 18 and 20, respectively. In this regard, it is important to note that the openings 36 and 38 can preferably not extend to a point beyond the length “L” of the filaments of the brush when stored within the jacket as this could permit the filaments to become disfigured by protruding outside of the openings 36 or 38.
Productivity guide and wear bars 27 and 29 are provided. Openings 36 and 38 extend lengthwise from each the respective upper ends 22 and 24 into the lower ends 26 and 28 respectively terminating a predetermined distance from a lower end edge 40 and 42, respectively, and are defined by top edge 60 and 62, bottom edge 64 and 66, respectively, and side edges 68 and 70, respectively. Productivity guide and wear bars 27 and 29 extend across the respective panels 18 and 20 transversely through the panel openings 36 and 38, respectively, and interconnect the side edges to retain filaments of the brush and serves as a visual productivity guide and wear indicator for filament length as well as lend rigidity and strength to the cover 10.
The productivity guide and wear bars 27 and 29 aid in retaining the filaments 13 of the brush 14. The productivity guide and wear bars 27 and 29 can preferably include a curved rib cross section which aid in guiding the filaments 13, broken and unbroken, into the jacket 12. The productivity guide and wear bars 27 and 29 provide a good visual indication of the productivity remaining of the brush 14 and aid in retaining filaments 13 within the jacket 12.
Accordingly, each lower end 26 and 28 of each panel 18 and 20, respectively, there remains a continuous transverse section to retain the filaments and into which the openings 36 and 38 do not extend. The plurality of openings 36 and 38 are thus located on the jacket 12 for allowing fluid such as paint, solvent, or air to circulate within the protective cover and about the filaments of the brush 14.
A handle opening 44 is formed in end surface 23 of the jacket 12 adjacent the upper ends 22 and 24 of the panels 18 and 20 allowing the handle 15 of the paint brush to protrude out of the jacket 12. The handle opening 44 is formed between laterally extending connecting surfaces 30A, 30B and 32A, 32B and ends 22 and 24 of each of the first and second panels 18 and 20 all of which serve to retain about the handle 15. Sides 32A and 32 B do not extend the panel 20 to permit flow of paint out of the end of the jacket 12 when closed.
One may open the jacket 12 to expose a hollow interior section 16. The interior section 16 is where the bristles of the paint brush 14 will be stored in wet or dry manner. The first panel 18 is connected together the second panel by a junction panel 50 and is characterized as a living hinge which is a special type of connector style that is bent while the plastic piece is still warm right out of the mold. Junction panel 50 includes a plurality of lower spaced openings 41 to readily permit drainage and which are separated by transverse portions 43 of panel 50. Opening the jacket 12 will expose the hollow interior section 16 enabling positioning the paint brush 14 within the jacket 12 and when closed protect the bristle or filament 13 configuration of the brush 14.
The openings 36 and 38 provide for retention of the bristles while being stored in paint in the case of the jacket 12 being submerged into paint with the brush 14 therein as seen in FIG. 1. Upon removal, these openings 36 and 38 provide for quick drainage of paint from the jacket 12 so that the jacket 12 can be readily opened without causing a paint spill. After removal of the brush 14 from the jacket 12, any remaining paint on the jacket 12 should easily drip off. After a job, the brush 14 is cleaned and disposed back in the jacket 12 where the openings 36 and 38 will allow air to circulate therein. The air will allow the bristles of the paint brush 14 dry quickly after being cleaned and prevent mold and mildew from forming inside the jacket 12.
The protective cover 10 can be preferably be molded such as by injection for example. In this way, the components herein described are integrally formed. While the application has made mention of a preferred use with professional paint brushes, it is conceived that the invention can be employed with various sized brushes, such as artist brushes or the like, wherein the protective cover 10 would be reduced in size to accomplish the intended goal of the invention.
While the invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that the foregoing and other changes in form and details may be made therein without departing from the spirit and scope of the invention.
