Abstract
A paint preservation device prevents leftover paint from drying by minimizing exposure of the leftover paint to air. The device may have a plunging lid for insertion into a bucket containing paint. A seal is formed between the plunging lid and the sidewall of the bucket. A hole through the lid allows air to escape when a user presses down on the lid, thereby removing the air to prevent the paint from drying. The aperture may be sealed with a cap. A tube may be attached at the aperture of the lid for extracting a smaller volume of paint from the bucket to a small container as a user presses down further on the lid, forcing paint through the tube. A method of use of a paint preservation device is also disclosed.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION
[0028] As discussed above, embodiments of the present invention relate generally to painting tools and particularly to a device for preserving leftover paint during storage.
[0029] Disclosed is a paint preservation device for preserving leftover paint for storage. The device prevents leftover paint from drying so the paint may be preserved for use on future painting projects. An advantage of the present invention is that it minimizes or eliminates exposure of the leftover paint to air, thereby preventing the paint from drying out.
[0030] Referring to the drawings,
[0031] Embodiments of a paint preservation device 10 may further comprise a plunging lid 24 that is configured for insertion into the inner volume of the bucket 12 through the opening 22 of the bucket 12. The plunging lid 24 may comprise a horizontal plate 26 having an outer edge 28 that corresponds to the cross-sectional shape of the inner volume of the bucket 12 to form a seal between the plunging lid 24 and the vertical sidewall 16 of the bucket 12. The plunging lid 24 is held in place within the bucket 12 by friction between the outer edge 28 thereof and the vertical sidewall 16 of the bucket 12. The plunging lid 24 may also comprise an aperture 30 therethrough for allowing air to escape the inner volume of the bucket 12 through the aperture 30 when a user presses the plunging lid 24 downward. The friction between the plunging lid 24 and the vertical sidewall 16 of the bucket 12 may be overcome by a user pressing downward on the plunging lid 24. Pressing downward on the plunging lid 24 increases the pressure of the air within the inner volume of the bucket 12 and under the plunging lid 24, thereby forcing the air out through the aperture 30. In this manner, the air in the bucket 12 may be expelled. When paint 32 is contained within the inner volume of the bucket 12, the air in contact with the top surface 34 of the paint 32 may be thus expelled from the bucket 12 through the aperture 30, by a user pressing downward on the plunging lid 24 until the plunging lid 24 comes into contact with the top surface 34 of the paint 32, thereby minimizing or eliminating contact of the paint 32 with air in the bucket 12. Embodiments of the present invention may further comprise a sealing device, such as a plug or a cap 42 to seal the aperture. The air having been expelled, the paint 32 is thereby left unexposed to the air and remains within the bucket 12 for storage without risk of drying out by exposure to the air.
[0032] In some embodiments, as shown in detail in
[0033] In some embodiments, the sealing device may be a plug (not shown) for plugging the aperture 30. In other embodiments, as shown in
[0034] The sealing devices described above, including a plug and a threaded cap, are not intended to be limiting. The sealing device may be any suitable sealing device known to a person of ordinary skill in the art, now or in the future, for use to seal the aperture 30. It is preferable that the sealing device be reversible, such that a sealed aperture may be unsealed and sealed again.
[0035] It may be desirable for a user to extract a small quantity of stored paint 32 from the bucket 12 without excessively exposing the surface 34 of the paint 32 to the air. Accordingly, referring to
[0036] In embodiments having a rim 38 extending only upward from the outer edge 28 of the horizontal plate 26 of the plunging lid 24, the plunging lid 24 may be pressed all the way down into the bucket 12 until it comes into contact with the bottom plate 14 of the bucket 12 to expel all, or nearly all, the paint 32 from the bucket 12. In embodiments having a rim 38 that extends downward from the outer edge 28 of the horizontal plate 26 of the plunging lid 24, a gap 52 necessarily remains between the horizontal plate 26 of the plunging lid 24 and the bottom plate 14 of the bucket 12, thereby preventing the last remaining volume of paint 32 in the gap 52 from being expelled. Leaving such a small volume of paint 32 in the bottom of the bucket 12 may or may not be desirable, depending on the application for which the paint preservation device 10 is being used.
[0037] In some embodiments, as shown in
[0038] For embodiments in which the tube 44 is a section of hose or other flexible tubing, such as rubber or plastic tubing, or the like, it may be desirable, in operation, to strip the remaining paint 32 from the tube 44 by squeezing the tube 44 between the thumb and a finger, for example, beginning proximate the first end 46 of the tube 44 and sliding toward the second end 48 of the tube 44. This practice may also allow a small remaining amount of paint 32 within the tube 44 to dry out, thus necessitating rinsing of the final remaining paint 32 from the tube 44, as described above.
[0039] In some embodiments, the tube 44 may comprise a sealing device 56 removably coupled to the second end 48 thereof, such as, but not limited to, a plug, a cap, or the like, to prevent any remaining paint 32 within the tube 44 from drying out. Such a sealing device 56 may be alternated between an open position and a closed position.
[0040] Referring to
[0041] It is understood that some embodiments do not comprise a bucket 12, but do comprise a plunging lid 24, as shown in
[0042] Many conventional paint buckets comprise a lip or rim that extends inward from the top edge of the vertical sidewall thereof. The lip or rim is typically configured to accept a press-on lid that may be applied by tapping the lid with a mallet until it is pressed onto the lip or rim. In some embodiments, the plunging lid 24 may be configured for use with a conventional paint bucket, wherein the paint bucket has a lip or rim that extends inward from the top edge of the vertical sidewall thereof. For example, the plunging lid may be deformable, sufficient for insertion of the plunging lid into the inner volume of the paint bucket, thereby bypassing the lip or rim thereof. In some embodiments, the plunging lid 24 may be made of a deformable material, or have components, such as the outer portions thereof, made of a deformable material, such that the plunging lid 24 may be deformed for insertion into a conventional paint bucket while maintaining sufficient rigidity for operation of the plunging lid 24 as described above. For example, in some embodiments, only the outer portions of the plunging lid 24 may be deformable, sufficient for insertion of the plunging lid 24, while the center portion remains rigid. It is also contemplated that the plunging lid 24 may comprise any of a variety of mechanical elements (not shown) that are hingedly or slidingly coupled together in such a manner as to allow the diameter of the plunging lid to be variable. In such embodiments, the diameter may be reduced for insertion of the plunging lid 24 into the bucket and increased again to form a seal with the inner surface of the vertical sidewall of the bucket. The advantage of such embodiments is that the plunging lid 24 may be used with any of a variety of existing conventional paint buckets having a lip or rim that extends inward from the top edge of the vertical sidewall thereof.
[0043] One of the disadvantages of any of a variety of conventional paint buckets having a metal lip extending inward from the top edge of the sidewall is that, even when the conventional paint bucket lid is replaced, engaging the metal lip, the metal lip may be subject to corrosion or rust. For example, many such metal lips are made of an iron alloy and the paint within the paint bucket is water-based. Rusting may occur when the metal lip is exposed to air and moisture. For this reason, some embodiments of the present invention, as shown in
[0044] A method of using a paint preservation device is also disclosed. As shown in
[0045] In some embodiments, as further shown in
[0046] In other embodiments, the method may further comprise: disengaging the sealing device; inserting an end of a suction hose of a paint sprayer through the aperture and into the inner volume of the bucket; and extracting paint from the inner volume of the bucket and into the suction hose in response to operation of the paint sprayer.
[0047] In other embodiments, wherein the bucket comprises a rim extending inward from around the top edge of the vertical sidewall thereof, the method may further comprise: deforming the plunging lid until the plunging lid is sufficiently small to pass through the opening of the rim; and restoring the plunging lid to its original form after it has been inserted through the opening of the bucket.
[0048] The components defining any paint preservation device may be formed of any of many different types of materials or combinations thereof that can readily be formed into shaped objects provided that the components selected are consistent with the intended operation of a paint preservation device. For example, the components may be formed of: rubbers (synthetic and/or natural) and/or other like materials; glasses (such as fiberglass) carbon-fiber, aramid-fiber, any combination thereof, and/or other like materials; polymers such as thermoplastics (such as ABS, Fluoropolymers, Polyacetal, Polyamide; Polycarbonate, Polyethylene, Polysulfone, and/or the like), thermosets (such as Epoxy, Phenolic Resin, Polyimide, Polyurethane, Silicone, and/or the like), any combination thereof, and/or other like materials; composites and/or other like materials; metals, such as copper, zinc, magnesium, titanium, copper, iron, steel, carbon steel, alloy steel, tool steel, stainless steel, aluminum, any combination thereof, and/or other like materials; alloys, such as aluminum alloy, titanium alloy, magnesium alloy, copper alloy, any combination thereof, and/or other like materials; any other suitable material; and/or any combination thereof.
[0049] Furthermore, the components defining any paint preservation device may be purchased pre-manufactured or manufactured separately and then assembled together. However, any or all the components may be manufactured simultaneously and integrally joined with one another. Manufacture of these components separately or simultaneously may involve extrusion, pultrusion, vacuum forming, injection molding, blow molding, resin transfer molding, casting, forging, cold rolling, milling, drilling, reaming, turning, grinding, stamping, cutting, bending, welding, soldering, hardening, riveting, punching, plating, and/or the like. If any of the components are manufactured separately, they may then be coupled with one another in any manner, such as with adhesive, a weld, a fastener (e.g. a bolt, a nut, a screw, a nail, a rivet, a pin, and/or the like), wiring, sewing, any combination thereof, and/or the like for example, depending on, among other considerations, the particular material forming the components. Other possible steps might include sand blasting, polishing, powder coating, zinc plating, anodizing, hard anodizing, and/or painting the components for example.
