Background of the Invention
The invention relates to wet storage devices for paint applicators, especially paint brushes and rollers which are used in painting the interiors and exteriors of buildings. Wet storage means the temporary storage of such paint applicators in a sealed container either immersed in a paint dissolving solvent or in an atmosphere of vapors of such solvent which may be turpentine or any other suitable paint thinner.
It is desirable to thoroughly clean a paint brush or roller every time it is used. However, this is time consuming and not always practical, especially if the painting project involves several days work. In such cases, it is much easier to simply store the paint brush or roller in a paint dissolving solvent which keeps the paint bristles and roller soft and pliable and ready for use. Most often, a paint brush is placed in a metal can which is partially filled with a paint thinning liquid. The paint in the brush normally settles to the bottom of the can and forms a sludge which impregnates and hardens on the brush, if the brush is stored for a lengthy period of time. The bristles become curved and distorted and harden in this position, making it impossible to use the brush again. Thus, it can be appreciated that the container in which the paint brush or roller is stored, is crucial to the continued life of the paint applicator.
U.S. Pat. Nos. 1,050,318, 1,110,533 and 3,955,670 are typical of the many patents which disclose a storage device that utilizes some type of metal clip for engaging the brush handle to suspend the paint brush in spaced relation from the bottom of a container which is partially filled with a solvent which keeps the paint bristles soft and pliable. U.S. Pat. Nos. 2,141,531 and 2,262,735 disclose typical storage devices which rely on some type of elastomeric seal for engaging the brush handle to support the paint brush in a container which is also filled with some liquid solvent. The invention is an improvement in such devices in that the container of the invention is much simpler and, therefore, more economical to produce and sell. Further, the seal used to engage and support the paint brush or roller is a wraparound-type seal which can be tightened, by hand, around the brush handle to insure that the brush handle will not slip through the seal into the container. The invention, contrary to the prior art indicated above, is readily adapted for use with paint rollers in addition to paint brushes.
Summary of Invention
Briefly stated, the invention is in a wet storage device which is primarily used to temporarily store a paint brush or roller. The device essentially comprises, (I) a hollow container for holding a paint cleaning solvent, (II) a cover for sealing the open top of the container, the cover having at least one small opening with radially oriented slits cut through the cover, the slits forming between them a plurality of flexible, pie-shaped segments for frictionally engaging and holding the brush or roller handle, and (III) a flexible seal which is tightly, conically wrapped around the brush handle in covering and sealing relation with the opening and slits to support the paint brush or roller in a desired position within the container where the paint bristles or roller are in spaced relation from the bottom of the container.

Description of Invention
With general reference to the drawing for like parts and particular reference to FIGS. 1-4, there is shown a device 10 which is used in the temporary, wet storage of a paint applicator, such as a paint brush 11 or paint roller 12 shown, respectively, in FIGS. 1 and 2. In this case, the brush and roller are placed in an atmosphere of vapor or fumes given off by the paint cleaning solvent 13 which is stored within the device 10.
The storage device 10, when in a vertical position, comprises a hollow, vertically elongated container 14 which may be any suitable shape, e.g. cylindrical as shown, for holding the solvent 13. The hollow cylindrical container 14 is composed of any appropriate material, such as solvent resistant plastic, and has a closed bottom 15 and an open top 16 which is vertically spaced above the bottom 15 which is formed by an integral, solid circular base 17 which has a laterally outstanding annular flange 18 which has an outer diameter that is substantially greater than the outside diameter of the container 14 to stabilize the container and prevent it from tipping over and spilling the solvent 13.
A solid, planar lid or cover 19 with a downwardly directed annular flange 20 for frictionally engaging the adjacent sides of the container 14, is detachably mounted on the open top 16 of the container to seal the solvent holding chamber 21, formed in the container, from the ambient atmosphere. The cover 19 is, likewise, composed of plastic and has at least one small opening 22 (FIG. 3) from which a number of similar slits 23, cut through the cover, extend in radial directions to form between them, a plurality of similar, pie-shaped, flexible segments or tabs 24 which, in effect, are integrally hinged to the cover 19, so that the arcuately-shaped free ends 25 of the segments 24, can be deflected downwardly or upwardly, as shown, out of the plane of the cover 19. The flexible segments 24 converge upwardly above the plane of the cover 19 to frictionally engage and help hold the handle 26 of the paint brush 11 and roller 12 within the chamber 21, so that the paint bristles 27 of the paint brush 11 and the roller 28 of the paint roller 12 are spaced from, and free of, the bottom of the container 14 which is important, since paint, which contaminates the solvent, settles to the bottom and forms a sludge which can adversely impregnate and harden on the bristles 27 or roller 28 to make these particular paint applicators unsuitable for further use.
A flexible seal 30 which is composed of any suitable material, e.g. plastic such as polyvinyl chloride, is tightly wrapped in conical relation around the handle 26 of the paint brush 11 or roller 12 to cover and seal the opening 22 and slits 23 and compressively engage the handle to reinforce holding the paint brush or roller in a desired position within the container 14. In fact, the seal 30 is the main support for the paint applicator. The seal is an arcuately-shaped segment which has a pair of opposing ends 31,32 (FIG. 4) which are detachably joined together in overlapped relation by an suitable means, e.g. Velcro brand fastener 33, when the seal is positioned around the handle 26. The positioned seal 30 is frusto-conically shaped with sides that converge upwardly away from the cover 19. The seal 30, as seen in FIG. 2, is designed to engage the handle of the paint roller 12 just below a 90.degree. bend in the handle to provide adequate support for the roller 28 in the container 14.
In the case of the paint brush 11, a flexible, generally C-shaped clamp or clasp 34 is placed partially around the paint brush handle 26 just above the seal 30 and acts as an abutment which is carried by the brush handle 26 for engagement with the seal to further insure that the brush handle 26 won't slip into the container 14. A short length of slit, polyvinyl chloride tubing was found to have excellent gripping characteristics for use as a clasp 34.
It can be appreciated from a study of the drawing that the wet storage device 10 can be built to accommodate one or a plurality of paint brushes, either alone or in combination with a paint roller. This is precisely the embodiment of FIGS. 5 and 6 which illustrate the wet storage of a paint brush 11, a paint roller 12, and a dauber 35 which is used to periodically wet the bristles 27 of the paint brush 11 and the roller 28 of the paint roller 12 to keep them soft and pliable in cases where the applicators are stored for extended periods of time.
The dauber 35 comprises a long handle 36 with an attached sponge-like, solvent absorbent head 37 which is used to contact and wet the bristles 27 and roller 28. The above-described opening, seal and clasp assembly can be used to hold the dauber 35 in place within the container 14. A larger opening with any suitable cap assembly can be used to greater advantage, since the larger opening will allow greater maneuverability of the dauber 35 within the container 14.
Thus, there has been described a novel wet storage device in which relatively unclean paint brushes and rollers, i.e. not thoroughly cleaned brushes and rollers free from paint, can be temporarily stored until they can be properly cleaned or reused in further painting. The device is simple, in design, and not readily susceptible to wear because of the unique, pliable seal which is wrapped around the handle to seal the container and provide support for the paint brush or roller within the container in spaced relation above the bottom of the container. The unique opening in combination with the surrounding flexible segments or tabs makes the device readily adaptable to a number of different size paint brushes or rollers, contrary to prior art devices which utilize openings which accommodate a limited number of different size brushes, much less any paint rollers.
