The present invention relates to the field of buckets, paint trays and other hand-carried containers for liquids and tools, particularly for the carrying and applying of paint.
The standard horizontal paint roller tray has remained in wide use despite many inventions directed at improving the worker's access to paint and at providing a roller paint distributing or spreading surface in convenient proximity to a stable paint-holding reservoir.
Some of the impetus for the present invention comes from the various shortcomings of the standard horizontal roller pan.
The problems with the standard pan include: lack of stability when used on a ladder; small paint capacity; and lack of portability. The instability experienced while a horizontal roller tray is carried has been demonstrated over the years and is known to all those skilled in the art of roller painting. A significant need exists for a more ergonomic alternative to the prevalent prior art.
From the year 1953, U.S. Pat. No. 2,659,917 by Drum teaches an improved surface for distributing paint on a roller for a horizontal paint tray. Drum provides a textured drainable surface where excess paint can be removed from the roller.
Currently it is common practice for people who paint with a roller to use a porous paint screen in a bucket, or to use a standard roller tray. Various specialty buckets are available which offer substantially vertical roller paint distributing elements. Several patents for such devises are listed below as well as other relevant prior art.

Exemplary preferred embodiments of the present invention are disclosed herein with reference to the several drawing figures. It will be understood by one skilled in the art that the various features and elements disclosed herein may be assembled in a multitude of alternative combinations and still fall within the scope of the present invention.
This description of exemplary preferred embodiments is provided as specific examples of embodiments within a group of variations, and it will be understood that this description and disclosure is not intended to limit the scope of the invention except as specifically announced in the claims.
A preferred embodiment of the present invention, as disclosed in
A preferred embodiment may also comprise various additional elements, which can comprise: a lid assembly 200, a pivoting handle assembly 400, a paint spreading grid or screen 70, a carrying strap 700, a removable liner 800, and a tool storage collar stop 850.
In a preferred embodiment, the invention can be laterally symmetrical about a vertical plane passing through the middle of the invention, this provides for complete ambidextrous functionality and can contribute to providing an ergonomic conceptual simplicity.
The container 100 can be capable of holding a quantity of liquid in a reservoir area 101 and/or a plurality of tools on a flange 103. The container can have a rear substantially planar wall 160 that is oriented in a near vertical position when the container is sitting on its bottom and resting normally on a horizontal surface.
There can be an open top side 180 which is at least partially surrounded by a substantially horizontal flange 103 protruding outward from near the top edge of the open top side 180. The flange 103 can contain holes 113, 114, 116, 119, 144 and/or recesses 155 for receiving putty and holding a tool or a plurality of tools. Portions of the tool flange 103 may be substantially vertical, like the side flange 133 and the rear flange 111. The side vertical flange 133 can be configured to hold a tape measure or similar clip-on item, including among other possibilities, a tool-holding pouch.
In an exemplary preferred embodiment, the top opening 180 can slope downward towards the front at an angle of approximately 30 degrees from the horizontal.
A preferred embodiment can comprise a lip 108 extending vertically upward around the periphery of the open top 180 when the container 100 is resting on a horizontal surface. The lip 108 can be capable of receiving a semi-sealing lid assembly 200. In contrast to the prior art for clip-on lids, the lip of the present invention may be vertical while the open top is inclined at approximately 30 degrees from horizontal. Thus removal of the lid occurs in a vertical direction 970, rather than perpendicular to the surface of the open top and lid as is found in the prior art.
The container unit 100 can be molded from a semi-flexible plastic such as high-density polyethylene or polypropylene, and formed with four substantially planar walls: a rear wall 160, two side walls 130; a front wall 140; as well as a bottom 170 and an angled open top 180. An outwardly protruding flange 103 can be provided around the periphery of the open top 180. A vertical, upwardly protruding lip 108 can also be provided around the periphery of the open top 180. The lip 108 can be configured to receive a sealing or semi-sealing lid assembly 200 with suitably shaped extensions 204, 203.
Radiused corners 128 of approximately ½ inch radius can be provided where the side walls 130 meet the rear wall 160. When viewed from the top (
As shown in
With reference to
When seen from the front, the ledges 168 can form a series of laterally symmetrical curves that have outer sections that form an upwardly convex curve of approximately 2.5 inch radius, said curves meeting along the invention centerline in a slightly rounded vertex 165, with an upwardly concave radius of about ½ inch. This pattern of ledges can provide extra traction for the roller as it is rolled on the container's substantially planar rear wall. This pattern is provided as a backup measure. For optimal performance, a separate paint spreading screen or grid 70 is provided by the invention.
The paint-spreading screen 70 of the present invention provides a combination of improvements over the prior art. In a preferred embodiment the paint-spreading screen 70 is a substantially planar assembly without any hooks on its top side 71. Hooks on the top edge are the norm in the prior art. Hooks are a versatile means of securing a screen in a variety of buckets, but the hooks tend to interfere with installing a sealing lid 200 on the container. The lid 200 can be useful for temporary storage of paint and painting equipment 60, 20, 30.
In a preferred embodiment of the present invention the paint spreading screen is engaged to fit securely in place within the container 100 by means of two slots 176 formed into both side walls 130 of the container in their respective lower portions. The slots 176 can be formed by the combination of inwardly protruding webs 175 on the side walls and the interior surface of the rear-side corner wall 128. The slots 176 can engage the side beams 72 in their lower portion 73 and the spreading screen assembly 70 is positioned in place as shown in the cross sectional view of
To position the screen 70 in an effective and secure position it can be desirable to provide the lower portions on the screen side beams 73 with a slight curvature 74, which is concave to the side facing rearwards. This curvature 74 can easily be adjusted by hand bending of metal side beams 72. The top 71 and bottom 75 edges of the screen benefit from deburring, but do not generally require supporting beams.
A pivoting bail type handle assembly 400 with special stop elements 117 can be provided by the present invention. The handle can be configured to pivot from a hole 122 in the container 100 vertical side flange 133, along a pivot axis 415. The handle can have a suitable bail 405 length such that the handle grip 410 will swing clear of the lower end of the cloth-holding flange 152 when swung forwards and down for stowage. At the other extreme of its swing travel the bail portion 405 of the handle assembly 400 can be configured to engage stop elements 117 on the container's outward side flanges 132.
By engaging the stops 117, the grip element 410 of the handle assembly 400 is positioned in a location approximately three inches above the corner defined by intersection of the horizontal rear flange 110 and the vertical rear flange 111. In this position, the combination of the handle grip 410, the bail 405 and the two rear flanges 110, 111 can form an ergonomic hand hold for gripping the invention, as depicted in
With reference to
A preferred embodiment of the present invention can be molded from a semi-flexible thermoplastic such as polypropylene and polyethylene. To reduce manufacturing costs and facilitate injection molding, it can be desirable to taper the walls 130, 140, & 160 inward as one moves downward from the open top 180. An inward taper of 2 degrees on each wall has been employed in several embodiments. On the inner face 161 of the rear wall 160 the faces 169 of the pattern can be angled to avoid undercut pulls in the molding process. To assure this, the length of the ledge portion 168 of the pattern can be less than the tangent of the overall wall taper or draft angle times the height of the substantially vertical face 169 between ledges 168. Since the sine of 2 degrees is approximately 0.035 the ledges 168 would need to be less than 0.028 inches wide if separated by a face height 169 of 0.8 inch (0.035″×0.8″>0.028″).
As shown in
The bottom 170 can be provided with various downwardly extended stiffening webs 173. The webs 173 can beneficially radiate outward from a central boss point 190 where plastic can be injected into the container mold. A downward tapering flange web 177 can extend down from around the periphery of the bottom 170. In an embodiment with legs, cutouts 178 can be provided in the bottom flange 177 for legs 610, 620, 630, 640 to protrude, as shown in
In a preferred embodiment depicted in
In a preferred embodiment one of the tool-holding areas 151 is configured to retain a cleaning cloth 90. The form of the cloth holder 151 can be a curved and approximately ‘V’ shaped hole in a downwardly turned portion 150 of the invention's tool-holding flange 103. In the lower part of the ‘V’ notch 153 the sides of the holder can beneficially become parallel or nearly so, to prevent the cloth 90 from working upward and falling out.
In a preferred embodiment, a portion of the tool-holding flange 103 can have receiving pockets 155 configured to hold a quantity of painter's putty, the putty holding areas can be formed by a pair of shallow recesses 155 located symmetrically on the front flange 150 of the container. For extra strength and rigidity, supporting webs 154 can be provided between the container front wall 140 and the front flange 150.
As shown in
As shown in
The lid assembly 200 can comprise a substantially vertically downward extending pair of lips: an outer lip 203, and an inner lip 204; these lips can be configured to mate with the upwardly extending lip 108 on the container 100 thus forming a substantially vapor-tight seal between the container 100 and the lid 201.
The slot 207 between the inner lip 204 and outer lip 203 of the lid 201 may beneficially comprise a wider gap at the base of the slot 208 and have a narrower gap at the entrance to the slot 209; the gap width near the entrance 209 can beneficially provide a snug fit on the container flange 108.
The container flange 108 may have parallel and vertical wall sides formed with considerable precision, so as to fit well in the slot 207 of the lid element 201. For a snug fit, the gap at the entrance to the slot 209 can be slightly smaller than the thickness of the container flange 108; 0.002″ to 0.005″ of interference fit may be found sufficient to assure a snug seal. The gap at the base of the slot may beneficially be wider than the width of the container flange 108 plus twice the thickness of a removable liner 800. With this dimensional form the lid lips 203, 204 can flex and allow said container lip 108 with a liner 800 installed to be inserted all the way into the base 208 of the lid lip slot 207.
Because of this widening of the gap towards its base 208, the mold surfaces forming the slot 207 may experience an undercut or reverse draft situation. To allow the lid 201 element part to eject from the mold it can be beneficial to put compensatingly large amounts of positive draft on the face 210 of the inner lip opposite to the slot face. The outer face 211 of the outer lid lip 203 can be formed by a second section of mold that joins to the first section containing the lid slot 207 forming plug. As the two mold sections separate, the lid part 201 can stay with the lid slot plug until the outer face 211 of the outer lip has cleared its second mold section. Once clear of this second mold section the outer lip 203 can flex and come off of the lid slot forming plug incorporated in the first mold section.
The lid element 201 may beneficially be molded from a semi-flexible thermo-plastic such as polyethylene. The plastic used for the lid 201 may beneficially be softer or more flexible than the plastic used to mold the container element 100.
A typical wall thickness of approximately 0.090 inches can be used in preferred embodiments of both container and lid.
As shown in
When pivoted away from the notch 206 as seen in
The lid 201, when closing, can utilize protruding tabs 225, which have ridges or extensions that can engage contours at 138 along the edge of the hole 137 in the tool flange 103 around the container body 100. This would provide a ‘snap into place’ function. These protruding tabs 225 can extend downward from the lid 201 when it is closed in the normal resting position of the container. The tabs 225 can engage an outwardly extending ridge 138 formed by the inner edge 138 of the elongated scraper-holding hole 137 in the container's side tool-holding flange 132, 103.
The lid 201 can be provided with a plurality of tabs extending outward from the edges of the lid. Two of the tabs 230 can be configured to insert into and be held securely in correspondingly shaped holes 115 in a horizontal flange 110 extending rearwards from the main container 100 body. The tabs 230 and slots 115 can beneficially be configured to assure that the lid will lie closely along side of the rear planar wall 160 on the exterior of the container 100 when the lid assembly 200 is in a rearward stowed position 202 as shown in
In a preferred embodiment shown in
The beams 72 can be configured to engage the slots 176 in the interior of the container. Slots 176 may beneficially be formed by the following combination: on one edge of the slot by flanges or webs 175 that extend approximately ½ inch inwards from the interior faces of the side walls 130 of the container 100; and on the other edge of the slot 176 by the interior surface of radiused corners 128 of the container 100.
The flanges or webs 175 can beneficially additionally perform the function of preventing jamming or locking together when multiple containers 100 are stacked for storage (without grids 70 in place). To effectively achieve this stack-defining function the flanges 175 can terminate in a substantially horizontal top edge 185 located some distance above the bottom of the container, per preferred example: if the lowest extent 179 of the bottom perimeter flange 177 is located 3.4 inches below the top edge 185 of the web 175, the stacking interval will be 3.4 inches. When stacked, the web flange 175 of a lower container will engage the bottom edge 179 of a container stacked above.

In a preferred embodiment shown in
In a position approximately above a magnet 500 an additional supporting element can be provided in the form of an oblong hole 137 in the side flange 132 running along the side of the open top 180 of the container. The perimeter of this hole 137 can provide additional support for a tool 30 attracted to and held by the magnet 500 to the proximal exterior face 520.
In a preferred embodiment, the magnet-equipped side walls 130 of the container can be formed by two substantially parallel elements that are offset laterally 135 from one another by a distance of approximately 0.15 inch. This offset distance can correspond to the approximate thickness of the magnets 500 contained within the walls 130 of the container 100. The offset 135 may provide for easier molding of magnet-holding pockets 550 within a plastic container part. The offset 135 can also contribute structural integrity to the side walls 130.
The magnet pockets 550 can comprise means of securely holding the magnets in position. The form of the magnet holding means can comprise molded plastic pockets 550 within the side walls 130; the pockets 550 being substantially open on the bottom side. The pockets can be additionally equipped each with two downwardly extending, tapered, semi-flexible plastic ‘ears’ or extensions 530 that will hold a magnet 500 firmly in place after the magnet 500 is snapped Into position from below. The taper of the ears 530 helps to ensure that the ears 530 can separate from the mold section that forms them, by means of bending and flexing of the ears 530.
The magnet 500 can be positioned within the side walls 130 such that a relatively thin layer of non-magnetic plastic covers the magnet on both sides 510 and 520. The thickness of the covering layer may taper and can be in the range of approximately 0.015 inch to 0.030 inch. This is in order to provide sufficient structural integrity while providing for a sufficiently short distance between the magnet 500 and a magnetically attracted tool 20, 30. A short distance can assure an adequate holding force between a tool 20, 30 and a magnet 500.
To effectively hold tools, the magnets 500 can be embedded within the side walls 130 of the container 100 in a location approximately one third of the way from the front top lip 108 of the container 100 to the bottom 170, and approximately one quarter of the way from the front wall 140 to the rear wall 160.
In a preferred embodiment bi-functional magnets 500 can be utilized to simultaneously hold a paint brush 20 as well as a scraping tool 30 with the same magnet 500. In the exemplary preferred embodiment, a magnet 500 is inserted into a close-tolerance receiving structure 550 located in the side wall 130 of the container.
The offset 135 in the side wall 130 can allow the magnet 500 to have close proximity to both a paintbrush 20 on the inside 510 of the container and a scraper tool 30 on the outside 520. The offset 135 can make for easier injection molding of the magnet pockets in the container 100. For example: in this preferred embodiment an approximately 0.025″ interior plastic wall between the side of the magnet and the metal band 21 around a paintbrush 20 allows a 0.75 inch diameter magnet 500 to firmly hold a brush 20. On the outside 520 of the magnet enclosure, an approximately 0.025″ thick plastic skirt 120 helps to hold and enclose the magnet, defining the magnetic flux gap spacing for gripping of a scraper tool blade 31.
As shown in
An outward extension 121 of the rear flange 111 can be provided. This extension 121 can form an enclosed area 112 which is capable of holding a strap 700 in place near a rear corner of the container 100. A narrow portion 124 of the area 112 can be narrow enough to grip a strap 700 as it is inserted into or removed from the enclosed area 112. The extension 121 can have a semi-flexible nature allowing it to flex as a strap 700 is inserted through the narrow gap 124. A hole 123 can be provided in the extension 121. By joining a hole 123 with a hole 119 with a length of cord or wire, the narrow portion 124 is effectively closed, preventing the strap 700 from being able to come out of the enclosed area 112.
The carrying strap 700 can comprise a pair of clips 730 (or snap hooks), which can be attached to the lower portion of the strap 750 in positions that enable the clips 730 (or snap hooks) to be detachably fastened to appropriate points on the container body, such as a pair of holes 119 in the rear horizontal flange 110.
As shown in
It is desirable to have the portions of the legs like 613 distal from their respective pivot axes flush or slightly above flush with the lowest portion 179 of the downwardly extending flange 177 that partially surrounds the bottom 170 of the container. When the legs are extended, it is desirable to have their distal portions like 613 below flush with the plane defined by the bottom 179 of the surrounding flange 177. The lower position of the distal ends 613 of the legs when extended helps to overcome any flex or slop in the leg pivots that might otherwise cause the container 100 to rock or wobble when resting on a flat horizontal surface.
The angling of the pivot axes may be achieved by angling the lower edge of a circular flange 612 that surrounds a pivot axis 611 on the container 100. The angle between the pivot axis and the vertical axis 970 of the container 100 can be called A1. The vertical axis of the container can be perpendicular to the plane defined by the bottom edge 179 of the container 100. As shown in
L1−L2=L3*SINE(2*A1)
which shows the convergence distance of two diagonally opposed axes 615, 635. The convergence of the axes causes a lowering of the leg ends 613 when extended. The lowering is shown by the arrows at 616 and 636 in
In a preferred embodiment, a removable liner 800 for the container 100 can be provided. The liner 800 can be formed to fit closely within the container 100, including fitting closely within any interior slots 176 designed to receive a paint spreading grid 70. This helps to assure that the grid 70 will still fit in place with a liner 800 installed.
The tool stop unit 850 can prevent a tool 854 from passing completely through a storage receptacle consisting of a through-hole, like 114, 116, or 144, in a substantially planar support element as may be found on the tool-holding flange 103 of the present container invention.
The stop collar can have a wavy form with the shape defined in polar coordinates, by the equation as a function of polar angle P1:
R1=B1+C1*SINE(N*P1)=interior edge shape
R2=B2+C2*SINE(N*P1)=outline edge shape
The integer N can be varied to provide a varying number of lobes as shown in
A preferred embodiment of the present invention can provide a tape roll holder 900. The tape roll holder 900 can be configured to hold a roll of tape 40, such as masking tape, or a plurality of such tape rolls. The tape roll holder can comprise: a lineal flexible element 910 with a first and a second end (such as a length of nylon cord); a magnetically attractable element 920 (such as a ferrous fob) attached to the first end 911 of said flexible element; means of attaching the second end 912 of said flexible element to the container 100, such as a loop; and a magnet attached to the container 500.
The magnet can be capable of holding the fob 920, and the magnet can be located at a distance from the second end attachment point 903 that is less than the length of the flexible element 910.
To use the tape holder 900, the fob 912 end of the flexible element 910 can be passed though the central hole 41 of a tape roll 40, and then the fob 920 can be attached to the magnet 500. To remove the tape, the fob 920 can be manually detached from the magnet 500 and the tape roll 40 removed from the container 100 assembly.
In the foregoing discussion we make the preferred embodiments exemplary of all the possible features and elements of the present invention. It will be clear to one skilled in the art that embodiments which are limited to employing only some of the features disclosed herein will also fall within the scope of this invention.
