Description

A CASE FOR PROTECTING THE BRISTLES OF A PAINTBRUSH BACKGROUND OF THE INVENTION

Field of the Invention

[0001] The present invention relates to painting accessories and, in particular, to an improved case for protecting the bristles of a paintbrush.

Description of the Related Art

[0002] Devices for protecting the bristles of a paintbrush when the paintbrush is not being used are well known. The device may be in the form of a bag similar to the type disclosed in United States Patent Number 5,174,445 which issued to Mull on December 29, 1992. Mull discloses a storage bag assembly for storing a paintbrush between uses. The assembly comprises a foil bag for receiving the bristles and the adjacent portion of the ferrule. The bag has a relatively flat bottom for supporting the bag in an upright position and a pair of vertical pleats for permitting an upper edge of the bag to be closed around the ferrule of the paintbrush. The paintbrush is provided with a relatively wide elastic band positioned in a stretched condition around the ferrule of the paintbrush. The elastic band is rollable onto itself to form a band of increased thickness to serve as a drip guard. The paintbrush can also be suspended on the edge of the foil bag by the rolled-up elastic band. The elastic band is unreliable downwardly over the upper edge of the foil bag to secure the bristles of the brush in the bag and seal the contents of the bag therein.

[0003] The device may alternatively be in the form of a case or sheath similar to the type disclosed in United States Patent Number 5,244,090 which issued to Keith on September 14, 1993. Keith discloses a comb and sheath assembly for protecting a paintbrush and maintaining bristles of the paintbrush in good condition between uses. The comb has a support and a series of teeth extending from the support. The sheath has opposed first and second halves. Each half has a base with an inner surface and an outer surface. There are also means for reversibly securing the halves together in a closed condition. Sidewalls extend between the bases of the halves when the sheath is in a closed condition to define, with the inner surfaces, an interior cavity and to define, with the outer surfaces, an exterior space. The sidewalls further define a handle opening therein sized to permit a handle of the paintbrush to extend therethrough. The interior cavity is suitable to receive the bristles and the handle opening is suitable to permit the handle to extend into the exterior space. There is also means for securing the comb and sheath together with the teeth being located in the exterior space. The condition of the bristles is maintained by combing the bristles with the comb.

[0004] The device may still alternatively be in the form of a holder similar to the type disclosed in United States Patent Number 6,757,931 which issued to Nordstrom on July 6, 2004. Nordstrom discloses a protective holder for use with a paintbrush. The holder has a flexible sleeve that is configured to be snuggly positioned about a substantial portion of a paintbrush. The sleeve has an aperture through which the handle of a brush may extend. The sleeve may also include absorbent material that captures liquid that dribbles down from the applicator portion of a paintbrush when the paintbrush is held vertically. The holder also has a protective segmented skirt that is operatively connected to the sleeve. The segments or panels of the skirt may be selectively moved between a protective storage position where the skirt substantially encircles the applicator portion of a brush, and a protective use position where the skirt substantially encircles the handle of a brush. The holder may also have a fastener to maintain the skirt in either of its protective positions. SUMMARY OF THE INVENTION

[0005] It is an object of the present invention to provide an improved case for protecting the bristles of a paintbrush between uses. [0006] It is also an object of the present invention to provide an improved case for protecting the bristles of a paintbrush which minimizes the need to chemically wash the paintbrush and reduces the discharge of paint residue and chemicals into the environment.

[0007] There is accordingly provided a protective case for a paintbrush comprising a releasably engageable body and a cap. The body has a mouth for receiving bristles of the paintbrush. The cap has an end wall and a skirt extending from the end wall. The end wall has an aperture configured to allow a handle of the paintbrush to pass therethrough. The bristles of the paintbrush are enclosed in the protective case when the cap and the body are engaged. [0008] There is also provided a protective case for a paintbrush comprising a body and a cap which are releasably and slidably engageable. The body has a mouth for receiving bristles of the paintbrush. The cap has an end wall and a skirt extending from the end wall. The end wall has an aperture configured to allow a handle of the paintbrush to pass therethrough. There is an absorbent liner disposed about the aperture in the end wall of the cap. The bristles of the paintbrush are enclosed and substantially sealed in the protective case when the cap and the body are engaged.

[0009] In one specific embodiment the skirt of the cap may receive the mouth of the body and fit slidable over an end of the body adjacent to the mouth of the body. There may be an outwardly projecting flange on the body functioning as a stop to restrict slidable movement of the cap along the body when the cap and the body are slidable engaged. There may also or alternatively be a contour in the skirt of the cap functioning as a stop to restrict slidable movement of the cap along the body when the cap and the body are engaged. The skirt of the cap may have an inwardly projecting rib and the body may have an outwardly projecting rib, wherein the inwardly projecting rib and outwardly projecting rib function to lock the cap on the body. The body may also have a wedge shaped receptacle portion opposite of the mouth. The wedge shaped receptacle portion may have a transversely sloped thin edge. [0010] In another specific embodiment of the case the mouth of the body may receive the skirt of the cap with the mouth fitting slidably over the skirt. The mouth of the body may have an inwardly projecting rib and the skirt of the cap may have an outwardly projecting rib, wherein the inwardly projecting rib and outwardly projecting rib function to lock the cap on the body. The body may also have a wedge shaped receptacle portion opposite of the mouth. The wedge shaped receptacle portion may have a transversely sloped thin edge.

[0011] The case disclosed herein keeps the bristles of the paintbrush wet with paint allowing a user to go for lunch, or home for the night or weekend, without having to wash the paintbrush or wrap the paintbrush in a paint soaked bag. This extends the life of the paintbrush without the need to wash the paintbrush.

DESCRIPTIONS OF THE PREFERRED EMBODIMENTS

[0023] Referring to the drawings and first to Figure 1 there is shown a protective case 10 for a paintbrush 58 which is shown in Figures 6 and 7. The protective case 10 includes a body 1 and a cap 14 which releasably engages the body. The body 12 has a mouth 16 at a first end 18 thereof and a receptacle portion 20 at a second end 22 thereof. The receptacle portion 20 of the body 12 is wedge shaped as best shown in Figure 4. Peripheral side walls, for example side wall 24 shown in Figure 4 and side wall 26 shown in Figure 1 , extend from the wedge shaped receptacle portion 20 to the mouth 16. There are additional side walls (not shown) opposite to side walls 24 and 26. Referring back to Figure 1 , the cap 14 has a planar end wall 28 and skirt 30 extending from the end wall 28. There is also an aperture 32 extending through the end wall 28 of the cap 14. In this example, and as illustrated by broken lines 100 and 102, the cap 14 is shaped to slidably fit over the mouth 16 of the body 12 with the skirt 30 of the cap 14 receiving the first end 18 of the body inside the cap. In other embodiments the skirt of the cap may be received inside the mouth of the body. [0024] There is an outwardly projecting lateral flange 34 extending about the body 1 of the case 10. The flange 34 functions to strengthen the body 12. The flange also functions as a stop to restrict slidable movement of the cap 14 over the body 12 towards the wedge shaped receptacle portion 20 of the body 12. Slidable movement of the cap 14 along the body 12 may alternatively be restricted by providing the skirt 30 of the cap 14 with a contour 36 which narrows a cross section of the skirt. There is a first plurality of outwardly projecting lateral ribs 38a, 38b and 38c disposed on a front of the body 12 between the flange 34 and the mouth 16 of the body 12. The ribs 38a, 38b and 38c extend substantially parallel to the flange 34 and function to lock the cap 14 on the body 12 through engagement with a corresponding inwardly projecting rib 40 disposed on the skirt 30 of the cap 14.

[0025] Referring now to Figure 2, there is a second plurality of outwardly projecting ribs 42a, 42b and 42c disposed on a rear of the body 12 between the flange 34 and the mouth 16 of the body 12. The ribs 42a, 42b and 42c extend substantially parallel to the flange 34 and function to lock the cap 14 on the body 12 through engagement with a corresponding inwardly projecting rib 44 disposed on the skirt 30 of the cap 14.

[0026] There is also a magnet 46 disposed on the rear of the body 12. As best shown in Figure 3, the magnet 46 is retained within a recess 47 defined by an annular projection 48. The annular projection 48 is circumambient to an elongate projection 50 which is disposed in a center of the annular projection. The elongate projection 50 functions to secure the magnet 46 to the body 12 by engaging an aperture 52 in the magnet. A suitable adhesive may also be used to secure the magnet 26 to the body 12. There are ribs 54a and 54b which each extend along a chord of the annular projection 48. The ribs 54a and 54b are disposed on opposite sides of the elongate projection 50 and function to help maintain the shape of the annular projection 48.

[0027] Referring now to Figure 5, the cap 14 is provided with an inner liner 56 formed of an absorbent material such as polyurethane which is capable of capturing and retaining paint drippings. The inner liner 56 is disposed about the aperture 32 in the end wall 28 of the cap 14. A suitable adhesive is used to secure the inner lining to an inner surface (not shown) of the end wall 28 of the cap 14.

[0028] In operation, and with reference to Figures 6 and 7, the protective case 10 is used to protect the paintbrush 58. The paintbrush 58 is conventional and includes a handle 60, a ferrule 62 and bristles 64. The bristles 64 are received by the body 12 while the cap 14 encircles the ferrule 62 of the paintbrush 58 in a nesting relation. It is possible for the cap 14 to encircle the ferrule 60 because the handle 60 of the paintbrush 58 extends through the aperture 32 in the end wall 28 of the cap 14 with the inner liner 56 sealing the cap against the handle. Accordingly, as best shown in Figure 7, sliding engagement of the body 12 and cap 14 encloses and substantially seals the bristles 62 in the protective case 10. This allows the bristles 62 to dry.

[0029] The wedge shaped receptacle portion 20 of the body 12 of the protective case 10 physically retains the bristles 64 in the form of a new brush and prevent the bristles from splaying. In this example, the body 12 of the protective case 10 is asymmetrical with the wedge shaped receptacle portion 20 having a transversely sloped thin edge 66. The protective case 10 may also be transparent or translucent to allow a user to readily determine the color of paint on the bristles. This allows the user to easily switch brushes depending on the color of paint required for a job when a number of brushes are disposed in corresponding protective cases. The magnet 46 (shown in Figure 2) on each protective case 10 allow the cases to be conveniently mounted on a metallic surface for storage or transport.

[0030] Referring now to Figure 8, a second embodiment of a protective case 80 is shown. The protective case 80 shown in Figure 8 is generally similar to the protective case 10 shown in Figures 1 to 7. However, a body 82 of the protective case 80 is provided with a plurality of inwardly projecting ribs 84a, 84b and 84c while a skirt 86 of a cap 88 of the protective case 80 is provided with an outwardly projecting rib 90. The skirt 86 of the cap 88 is received in a mouth 92 of the body 82 as illustrated by broken lines 106 and 108. The mouth 92 of the body 82 fits slidably over the skirt 86 of the cap 88. The inwardly projecting ribs 84a, 84b and 84c and the outwardly projecting rib 90 function to lock the cap in the body.

[0031] Referring now to Figure 9, a third embodiment of the protective case 110 is shown. The protective case 110 shown in Figure 10 is generally similar to the protective case 10 shown in Figures 1 to 7 with like parts being given like reference numerals in the " 100" series. For example, in Figure 1 the body of the case 10 is called out by reference numeral 1 while in Figure 9 the body of the case 10 is called out by reference numeral 112. However, instead of a plurality of inwardly extending ribs, the body 112 of the protective case 110 is provided with grooves 92a, 92b, and 92c for receiving the inwardly projecting lateral rib 140 disposed on the cap 114. This allows for step locking of the protective case 110.

[0032] Referring now to Figure 10, a fourth embodiment of the protective case 110 is shown. The protective case 180 shown in Figure 10 is generally similar to the protective case 80 shown in Figures 8 with like parts being given like reference numerals in the " 100" series. For example, in Figure 1 the cap of the case 80 is called out by reference numeral 86 while in Figure 10 the cap of the case 180 is called out by reference numeral 186. However, instead of an inwardly extending rib, the cap 186 of the protective case 180 is provided with groove 94 for receiving one of the outwardly projecting lateral ribs 184a, 184b and 184c disposed on the body 112. This allows for step locking of the protective case 180.

[0033] It will be understood by a person skilled in the art that many of the details provided above are by way of example only, and are not intended to limit the scope of the invention which is to be determined with reference to the following claims.
