Field of Use
Rollers come in a variety of shapes, sizes, diameters and lengths and are used for a variety of applications, such as, for example, painting or for applying glue for flooring or sheet goods. Typically, the rollers include a nap that can be impregnated and/or coated with a coating material (e.g., paint, shellac, glue or the like) and then used to coat a surface with the material.
The cleaning of a wet or soiled roller cover after the applying process is a highly undesirable, sometimes impossible with glue(s) and some darker paint colors such as red or yellow, is a very time consuming process and is often ignored by the user leading to the destruction of the paint roller cover as the wet material, sets and are usually thrown away and replaced by new ones for the following day's work.
In many cases the same paint roller cover is intended to be used for the same paint material after a period of time for example while a first coat of a paint material sets or is stored for future touchups of the same color paints. In many glue type applications the roller cover could be stored for the next several projects and thus saving resources.
Paint rollers have three major components: core, adhesive, and fabric. The core is the base of the paint roller. The core can be constructed from a wide range of materials known to one skilled in the art (e.g. plastic, cardboard, and phenolic-impregnated materials). An adhesive is applied to the outside of the core and is utilized to attach the fabric. Typically, the adhesive is epoxy based. Other adhesives known to one skilled in the art are also utilized. The fabric of the roller typically comprises fibers woven or knitted to a backing and adhesively applied to the roller core. Fabrics include natural fibers (e.g. wool, mohair, and lambskin) as well as synthetic fibers (e.g. nylon, polyester, acrylic, rayon, and blends of one or more synthetic fibers).
The present invention provides a simple, inexpensive, and compact means of storing a wet-filled roller, whereby the material will remain fresh and uncured. Prior attempts have been made to achieve this objective.

As discussed in column 3 at line 7, the brush is positioned in a heavy foil bag which is pleated and tapered to provide a relatively large base. The liquid in the bag provides ballast to prevent tipping. The foil from the bag is similar to that in which vacuum packed coffee is sold. Further at line 20, the pleats of the bag are secured together by complementary look and loop fastener members. The bristles of the brush are sealed in the bag by a large wide elastic band such as a rubber band.

The bag as discussed in column 5 at line 33, has a rolled edge or partly rolled with an angular ring of absorbent material covered by the rolled edge. The material for the bag can be a woven, knit or felt cloth and may be fine, course, thick or thin. The coating applicator is applicable for painting, but also renders paint brushes suitable for applying stains, varnishes and the like.

The sachet is sealable around the brush handle, or is provided with means for sealing the open mouth of the sachet around the handle to restrict air into the sachet. In column 5 at line 18, the sealed sachet comprises two multiple lamina, paper laminar layer and a plastic foil laminar layer, such as is commercially available for variety of different purposes in the packaging art. The layers are heat sealed one to the other around the periphery to form a sealed sachet containing a small quantity preservative liquid. At line 25 the inner surfaces of the sachet are metal foil, the outer layers are paper or plastics and suitable for printed advertising matter or instructions or both.

No. 4,765,123 (Caldwell) discloses a process for covering a paint tray so that it may be reused without the necessity of cleaning As discussed in column 2 at line 9, the flexible paint impervious bag has an opening with a girth sufficiently large fit over the floor end of the paint tray. The girth is sufficiently large so that the bag in addition to fitting over the floor end is also large enough so that it lies down into the floor of the tray against the inner surface of the sides. Paint can be held within the tray and along the outer surface of the bag, allowing the tray to be used in a conventional manner but avoiding the necessity of cleaning the tray.
U.S. Pat. No. 4,738,358 (Kehl) discloses a paint roller cover container and extractor assembly simplifying the cleanup process.

The spatial protrusion is performed as a wedged shaped cavity.
U.S. Pat. No. 4,334,416 (Turano) presents an apparatus for soaking and preserving paint roller cover sleeves having an open top receptacle with bottom and side walls for holding a quantity of solvents, and a removable cap for sealing the open top portion of the container together with a post having an enlarged foot at the bottom for engaging the inside bottom of the receptacle to support the post in an upright position.
U.S. Pat. No. 3,757,990 (Buth) discloses a flexible liner for protecting a paint tray and a mechanical means for removing the flexible liner to the tray. The clips for clamping the liner to the walls of the tray act as the mechanical means, or a resilient band/drawstring or adhesive can be used to fix the liner to the tray.
U.S. Pat. No. 3,167,178 (Saunders) discloses a paint brush wrapper whereas discussed in column 1 line 45 an envelope has two sides and is preferably made of plastic material. The envelope is of substantially rectangular configuration and has four edges. Each of the four edges are joined along the other to form the envelope. The first opening is formed in the envelope along one of the edges and is substantially long enough to admit the bristles of the brush and the handle in the longitudinal direction of the handle. The flap as discussed on column 2 line 11 is formed with the envelope, extends from the side, along the edge and is adapted to fold and close the opening. A snap is provided to secure the flap to the side of the envelope.
This invention relates to an encapsulating method and device for storing a hollow roller cover particularly when the cover is wet with material in an unset condition. Unlike any prior art, this encapsulating method comprises using the hollow interior cylindrical portion of a roller cover, an oversized plastic bag, inserting the excess plastic bag into one end of the roller cover then inserting a cylindrical sleeve devise which wedges the plastic between the inner hollow roller cover and the outer cylindrical end of the sleeve devise, thereby hermetically sealing the wet roller cover creating an air tight capsule or enclosure to form an unconventional cylindrical enclosure.
The purpose of the invention is to eliminate the need for bulky, expensive, ineffective and time consuming methods of maintaining a wet hollow roller cover for use at another time. The invention thus saves time, money and supplies for the consumer.
One object of the present invention is to provide a means to store a used hollow roller cover between sessions without the need to clean the roller.
Another object of the present invention is to store a wet hollow roller cover for future use.
Another object of the present invention is to keep the wet material on the hollow roller cover from drying during a period of non-use.
Another object of the present invention is to be inexpensive and manufactured easily.
Another object of the present invention is to be simple to use and store.
Other objects will be apparent from the following Descriptions and Drawings.
