Home owners will periodically desire to repaint walls in their home. However, there is no current option for quickly, easily, and reliably testing various new paint colors that the home owner may want to test before buying the paint in bulk quantities. Though this issue has presented itself innumerable times for over a century, no solution has been presented in the art. For the foregoing reasons, there is a pressing, but seemingly irresolvable need for quick, easy, and reliable paint tester.
Wherefore, it is an object of the present invention to overcome the above mentioned shortcomings and drawbacks associated with the current technology. The present invention is directed to methods and apparatuses that satisfy the above shortcomings and drawbacks.
The present invention also relates to methods and paint testers comprising a sealed receptacle, an applicator, and a seal cutter. According to a further embodiment the paint tester comprises a cap which removablely encapsulates and provides a substantially fluid tight barrier around the applicator. According to a further embodiment the sealed receptacle includes a base, a receptacle wall, and a channel. According to a further embodiment the channel has a channel walls defining a space in fluid communication with an interior of the receptacle. According to a further embodiment a seal extending over a channel exit provides a fluid tight barrier to the interior of the receptacle. According to a further embodiment the seal cutter engages with an exterior surface of the channel walls. According to a further embodiment the seal cutter has one or more teeth extending in a direction of the seal. According to a further embodiment the seal cutter has a threaded interior surface that mates with a threaded exterior surface of the channel walls, such that when the seal cutter is rotated with respect to the receptacle, the one or more teeth will cut into and break the seal. According to a further embodiment the receptacle has first ratchet teeth that mate with second ratchet teeth on the seal cutter, such that the seal cutter may only be rotated in one direction relative to the receptacle. According to a further embodiment the receptacle has rotationally stationary first stops that engage with second stops on interior surface of the seal cutter, so as to prevent the seal cutter from being rotated relative to the receptacle to a distance sufficient to cut into the seal, until a force greater than a determined breaking force is applied. According to a further embodiment when the cutter is rotated fully, the seal cutter forms a fluid tight barrier with the exterior walls of the channel, but not with the channel exit. According to a further embodiment the seal cutter has a conduit that is aligned with a channel exit of the receptacle. According to a further embodiment the conduit extends into a crevice defined in an interior of the applicator. According to a further embodiment the conduit extends between one half and three fourths a distance from a base of the applicator to a top of the applicator, and a top end of the conduit defines a plurality of crenulations encircling a conduit exit. According to a further embodiment the applicator has a tapered shape, with a base of the applicator multiple times wider than a top of the applicator. According to a further embodiment the applicator is a foam brush. According to a further embodiment the receptacle is made of one of polypropalene or polyethylene. According to a further embodiment the receptacle base is transparent and the receptacle walls are opaque. According to a further embodiment the paint tester includes a volume of paint substantially filling an interior of the receptacle.
The present invention further relates to products and methods of testing paint using a paint tester having a sealed receptacle containing paint, a foam applicator, and a seal cutter, comprising rotating the seal cutter with respect to the receptacle until one or more teeth will cut into and break a seal on the receptacle, applying inward pressure to an exterior surface of a receptacle wall causing paint to flow from the receptacle through a channel exit of the receptacle, through a conduit defined in the seal cutter, out a conduit exit encircled by crenulations, through pores in the applicator, and onto an exterior surface of the applicator, and touching the exterior surface of the applicator to a surface upon which paint is desired.

Turning now to
The receptacle 4 is a preferably elongate container with a base 12, a wall 14 extending from the base 12, and a channel 16, all defining an interior 18 of the receptacle 4. The channel 16 is connected to an upper portion of the wall 14 by a ledge 20. The wall 14 is preferably opaque, to prevent paint 22 held within the receptacle 4 from being exposed to light. In some embodiments, the wall 14 may be all or partly transparent. In some embodiments including an all or partly transparent wall 14, an opaque covering, such as a wrapping, may be included to block light. Where there is an opaque covering, a clear window in the wrapping, preferably with removable an opaque flap, may be provided, to allow a purchaser to see the true color of the paint 22. In other embodiments, the receptacle 4 may have a transparent base 12, and preferably either an opaque wall 14 or a transparent wall 14 with an opaque covering. This would allow a purchaser to lift up the paint tester 2 and turn it over to see the true color of the paint 22, but still block light from reaching the paint 22 if the paint tester 2 was stored in an upright position, with the base 12 adjacent to a base of a storage or display box or other surface.
The wall 14, base 12, and channel 16 are preferably formed of a polymer plastic, such as, for example, polypropylene and polyethylene. Other plastics could include PLA or other biodegradable plastics.
The paint 22 stored inside the paint tester 2 is preferably latex paint. In other embodiments, an oil-based paint 22 could be stored in the paint tester, preferably with a metal or other lining on the inner surface 24 of the receptacle 4 that resists degradation from oil.
The channel 16 has channel walls 26 defining a channel space 28 in fluid communication with a remaining interior 18 of the receptacle 4. A seal 30 extends over a channel exit 32, and provides a fluid tight barrier to the interior 18 of the receptacle 4.
The seal cutter 6 preferably has threaded radially interior seal cutter walls 34, which matingly engage with threaded exterior channel walls 36. The seal cutter 6 has one or more teeth 38, aligned with and extending in a direction of the seal 30, but preferably initially spaced from the seal 30. When the seal cutter 6 is rotated with respect to the receptacle 4, the mating threaded walls 34, 36 cause the respective rotational motion to also cause linear and downward motion on the seal cutter 6, downward being in a direction toward the base 12 of the receptacle 4. With continued respective rotation, the one or more teeth 38 on the seal cutter 6 will cut into and break the seal 30 that extends over the channel exit 32, and thereby break the fluid tight barrier to the interior 18 of the receptacle 4 and the paint 22 stored within.
When the seal cutter 6 is rotated fully, such that the seal cutter 6 is fully screwed onto the channel 16 and further relative rotation is mechanically prevented, the seal cutter 6 forms a fluid tight barrier with the exterior walls 36 of the channel 16, while providing an opening to the channel exit 32.
Once the seal 30 is opened, the seal cutter 6 is preferably prevented from unscrewing from the channel 16, and thereby failing to maintain a fluid barrier and allowing unintended paint 22 leakage. To prevent relative unscrewing between the seal cutter 6 and the receptacle 4, the receptacle 4 has first ratchet teeth 40 that mate with second ratchet teeth 42 on the seal cutter 6. The respective alignment of the first and second ratchet teeth 40, 42 allow the seal cutter 6 to only be rotated in one direction relative to the receptacle 4, and thus prevent unscrewing of the seal cutter 6.
To prevent the seal cutter 6 from being inadvertently rotated with respect to the receptacle 4—before a paint tester 2 is purchased for example—and thus prematurely cutting into and breaking the seal 30, the receptacle 4 has first stops 44 and full stops 46 disposed on an exterior of the receptacle adjacent to the threaded exterior channel walls 36. The first stops 44, in the form of breakable tabs 44, engage with second stops 48 on a radially interior surface of the seal cutter 6, and resist relative rotation of the seal cutter 6 and receptacle 4 up to a breaking force threshold. Past the breaking force threshold the tabs 44 would break or fold and allow the seal cutter 6 to continue to rotate around the receptacle 4. Thereby, the first and second stops 44, 48 prevent the seal cutter 6 from being inadvertently rotated relative to the receptacle 4 a distance sufficient to cut into the seal 30. The breaking force would be a twisting force or torque of a magnitude large enough to provide substantial tactile feedback, but small enough that an average adult could easily overcome it. The breaking force is preferably between 0.1 and 5.0 Nm, more preferably between 0.5 and 3.0 Nm, and most preferably between 1.0 and 2.0 Nm. The optional full stops 46 would engage the second stops 48 a given distance of rotation past the first stops 44, and fully prevent the seal cutter 6 from being over tightened and striping the treads on the threaded interior seal cutter walls 34 and threaded exterior channel walls 36.
In alternative embodiments, first stops 44 may be more robust, resisting folding or breaking, and be disposed on a removable stop collar that encircles the exterior of the channel walls 26. The stop collar would be rotationally stationary with respect to the receptacle 4, but removable, either by peeling off, or pulling up over the channel exit 32, for example. Thereby, the first and second stops 44, 48 prevent the seal cutter 6 from being rotated relative to the receptacle 4 a distance sufficient to cut into the seal 30, until the stop collar is removed.
The seal cutter 6 has a conduit 50 that is aligned with the channel exit 32 of the receptacle 4. The conduit 50 extends into a crevice 52 defined in an interior of the applicator 8. The conduit 50 preferably extends between one half and three fourths a distance from the applicator base 54 to the applicator top 56, and a conduit top end 58 defines a plurality of crenulations 60 encircling a conduit exit 62. Perforations may be used in place of or in addition to the crenulation 60 to help disperse paint 22 from the conduit exit 62.
A snap fit is preferably formed between the cap 10 and the seal cutter 6, when the cap 10 is fully seated on the seal cutter 6. In the embodiment shown, the snap fit is formed with a circumferential ridge 64 on the exterior circumference of the seal cutter 2 and a mating circumferential grove 66 on the interior circumference of the cap 10. This snap fit provides for a fluid tight barrier around the applicator when the cap is fully seated on the seal cutter 6. In further embodiments the ridge 64 may be on the cap 10 and the grove 66 on the seal cutter 6. In still further embodiments, other fluid tight designs allowing the removable attaching of the cap 10 to the seal cutter 6 may be provided, including mating threaded surfaces.
The applicator 8 preferably has a tapered shape, allowing for even paint 22 dispersion and a more natural painting motion when a user applies the paint 22 to a surface. As shown in
To use the paint tester, the user would first either apply a breaking force to turn the second stops 48 past the tabs 44, as in one embodiment, or would remove the stop collar 46, as in another embodiment. The seal cutter 6 would then be rotated with respect to the receptacle 4 until one or more seal cutter teeth 38 cut into and break the seal 30 on the receptacle 4. The user would then apply an inward pressure to an exterior surface of a receptacle wall 14, such as squeezing the wall 14 inwardly with his or her hand, causing paint 22 to flow from the receptacle 4 through the channel exit 32 of the channel, through the conduit 50 defined in the seal cutter 6, out the conduit exit 62 encircled by crenulations 60, through pores in the applicator 8, and onto an exterior surface of the applicator 8. The user would then touch the exterior surface of the applicator 8 to a surface upon which paint 22 is desired, causing the paint 22 previously stored in the interior of the receptacle to attach to the surface upon which paint 22 is desired.
In the embodiment shown, there is substantial exterior radial symmetry, and the left, right, and back plan view of the paint tester of
