Description
SPECIFICATION
This invention relates to a manually operable tool for masking surfaces from paint.
The masking stick comprises a tube which houses a solid masking material and through which the solid masking material is advanced, which masking material temporarily masks a surface from paint, varnish or other coatings by applying a temporary masking coating by rubbing an exposed portion of a solid paint masking material directly onto the surface to be masked, and thereafter removing said masking coating onto which paint varnish or other coating has adhered. The invention also involves a novel process wherein a surface is masked by the application of a temporarily coating by means of rubbing and shearing off the exposed portion of a paint mask solid onto the surface, thereby depositing a film which may thereafter be painted and subsequently removed by wiping it away with a cloth. The present invention meets the need in the art by providing a solid material that renders a convenient and accurately applied paint mask fir windows and other surfaces requiring masking protection from paint or other coatings.
The present invention's ease, non-drip accuracy in application and absence of required drying period overcomes the disadvantages present in spraying, squeezing, rolling and brushing liquid paint and coating masks. lBecause the mask material and paint are simply wiped away with a cloth, the use of razorblades which might damage the underlying surface is avoided.
A preferred embodiment of this masking tool and process involves the painting of windows. Painting window frames is a tedious and time-consuming task as the painter desires to fully cover the window frame while avoiding getting the paint on the window pane itself. Often windowpane glass is separated by narrow dividers known as mullions.
The mullion is a slender member placed between adjacent panes of glass supported by a flange and held in place by putty, caulk or a narrow strip of wood that covers the outside edge of the glass adjacent the mullion. When window frames or mullions are painted, the paint which otherwise gets on the windowpane nnust be thoroughly removed.
Past efforts at keeping paint from gc;tting onto the windowpanes had been accomplished by masking the glass with tape along the perimeter of the pane where glass meets frame or mullion. When masking, an adhesive coating or tape is placed on the windowpane so that the trim or frame material c;an be painted quickly and without regard to the juncture between glass and trim since any excess paint will be applied to the protective coating. However, taping is laborious and time consuming and removing the tape from the glass often presents problems, particularly where the tape hardens or becomes tacky. Where tape has not been employed, paint must be scraped off the glass typically with a razor blade. Another method of masking involves a triangular mask with an adhesive strip around the perimeter. The triangular mask is applied to the glass surface and overlapped to cover the entire surface with a portion of the mask.
Portions that overlay the mullions would need to be cut off so as not to interfere with the painting of the frames. Another device provides a flexible narrow blade with a straight edge that contacts the mullion. The ends of the blade are cut at an oblique angle. Two adjacent blades join at a corner of the window. A rubber vacuum cup attaches to each of the blades for securing the blade to the glass. Another device has a spring clip that engages opposed mullions frictionally. The clip presses a cardboard paint shield firmly against the adjacent windowpane. Another device involves a fitting that permits the application of caulk along the perimeter of the pane which caulk may be peeled off subsequent to painting. Yet another window mask product consists of a razor blade mounted on a squeeze bottle containing a liquid paint mask composed of petroleum distillates, which mask is applied to the window's perimeter through a sponge applicator pad and left to dry. After the mullions and frame are painted the paint and :mask drippings are scraped off with the attached razor blade.
Each of the foregoing paint mask efforts is plagued with drawbacks. The triangular shield designed to fit over the glass must be cut to size and the overlaps of triangular sections leave gaps that allow paint to seep onto the glass. The blade-style shield alluded to are labor intensive and require .accurate positioning of adjacent shields to protect the glass surface. The cardboard shield becomes damp with paint and losses its effectiveness to seal the glass from painting. A spring clamp must be inserted to hold the cardboard sheet to the window. The caulk applicator requires the costly purchase of caulk, the manipulation of a relatively cumbersome caulk applicator, caulk build-up within the applicator, and time-consuming cleanup i:ollowing caulk application. The razor blade/squeeze bottle method suffers the disadvantage of dripping, it requires time to dry onto the protected surface prior to painting, its petroleum distillate composition is an irritant to skin and eyes, and the use of a razor blade to remove paint scratches treated and energy efficient glass.
Commercial efforts at paint masking include the use of masking tape, caulk, masking paper and liquid paint masks. The liduid paint masks are applied by spraying, sponging, brushing or rolling. Hand-held portalble paint mask applicators include a hand-held masking machine which applies masking paper to a desired location, and a fitted nozzle for a caulk gun that permits a bead of caulk to be applied along a window pane's edge and later peeled away. Accordingly, there: is a need in the art for an improved mask for glass to prevent painting the glass while painting mullions.
In the case of masking window panes, tile mask is dispensed as a film along the perimeter of a windowpane and thereafter wiped off along with any errant paint. The paint mask comprises a solid stick, not unlike those found in crayons, lip balms and glue sticks.
The stick may contain glycerin, glycol or other substances that retard paint adhesion, and be of such rigidity that it shears off and leaves a film upon the glass by means of dragging the stick's end along the glass' surface. Following painting, the film disadheres and from the glass by wiping it with a cloth. The solid paint mask may be applied as a crayon, or housed and advanced thorough an applicator resembling a lip balm or glue stick dispenser and which may be manufactured from plastic or some similarly rigid material.
The mouth of the applicator should have at least one corner whose angle measures 90 degrees or less to fit easily into right-angled window frames. Th.e container's cap forms an angle at its tip.
Hence, the cap seals and protects the solid mashing material housed within the container and doubles as a scraper which may be used to remove difficult paint drips.
The method of the present invention will be useful to painting contractors, homeowners, hobbyists, or anyone who paints non-glass materials that are adjacent to glass-like surfaces rapidly and inexpensively.
My invention employs a novel coating process whereby a solid mask material would, in the course of rubbing it onto glass, shear away and thereby deposit a protective paint masking coating onto the glass. Candle waxes and bars of soap offer this shear-off film-depositing characteristic when dragged over glass. The introduction of paint masking ingredients such as glycols or glycerin into a frictionally coating-dispensing solid that shears away when rubbed onto glass, dispenses a coating that exhibits paint masking qualities characteristic to glycerin and glycols. l;~erivatives of polyhydric alcohols, such as sorbitol and glycerin and polyglycol esters of fatty acids and glycols such as (a) ethylene glycol (b) diethylene glycol (c) triethylene glycol (d) propylene glycol (e) dipropylene glycol and (f) tripropylene glycol, display the hygroscopic property of moisture retention, making them minimally adhesive to materials like glass. These masking materials are currently used in liquid paint masks that are sprayed onto surfaces to be protected. A
solid masking crayon or similar tool containing a hygroscopic glycol, may be dragged upon a surface and thereby provide a precise and uniform masking layer.
Appropriate coating-dispensing mediums into which paint masking agents may be introduced are manufactured in a variety of ways. Conventional alkali salt soaps that are manufactured by traditional saponification processes may be used. Modified soaps referred to in the industry as "syndets" may be used as well. Syndets differ from conventional soaps in that they are not formed totally from fat and alkali as conventional soaps are. Neutrogena® Soap (Neutrogena Corp.) is an example of a transparent, nondetergent modified bar soap consisting of trif;thanolamine,stearic acid, tallow, glycerin, coconut oil, castor oil, sodium hydroxide, oleic acid and cocamide DEA.
Another is Basis.TM. Glycerin Soap (Beiersdorf), which is .a transparent modified bar soap consisting of tallow, coconut oil and glycerin. Syndets provide an appropriate film dispensing medium that shears when rubbed onto glass. The fact that syndets mix well with glycerin and glycols makes them particularly suitable for paint masking purposes.
Ullmann's Industrial Encyclopedia of Industrial Chemistry provides a following listing of ingredients generally used by the cosmetic industry manufacturing syndets:
Component Content Fatty alkyl sulfates 30 - 60 Builders/Plasticizers:
Mono-,di-, and triglycerides Para~ns, microwaxes, fatty alcohols30 - SO
Fillers: starch, talcum, zinc Oxide, titanium oxide 0 - 15 Refatting/superfatting agents:
Lecithins, lanolin, oils, Alkanolamides 1 - 7 Active ingredients: D-panthenol Vitamin E, amino acids, Disinfectants 1 - 3 Water and moisturizers:
Lactates, amino acids, Sorbitol, glycerol 1 - 5 Coloring agents 0 - trace Perfumes 0 - 1 To create an effective paint-masking solid as described in the present invention the syndet is combined with the following materials in the proportions as shown:
syndet 10 grams distilled water 10 grams glycerin 20 grams Liquify the syndet by heating. Stir in 10 grams of distilled water and 20 grams of glycerin.
Let liquid cool to a solid while stirring intermittently.
Syndets currently manufactured often possess a high propylene glycol content, thereby bestowing desirable paint masking qualities to the medium. Syndets manufactured by Surrey, Inc. of Austin, Texas in the United States list ingredients in descending order:
propylene glycol, water, sodium stearate, sodium laureth sulfate, glycerine, sorbitol, sodium tallowate, sodium cocoate, triethanolamine. To this syndet medium are added distilled water and glycerin in proportions described herein to render a masking solid that exhibits appropriate dispensing and paint masking characteristics.
It is anticipated that the paint mask solid will be housed in and advanced through, a hand-held tubular container, to wit; a block-shaped lip balm-type dispenser with a moisture-locking cap and movable base. The b<~se advances the paint mask solid through the dispenser and a cap seals the dispenser's contents. The container's aperture shall be angular and conform to the shape of the tool end of the stick so the paint mask may provide coverage in window corners as well as along the window's perimeter.
The particular embodiment was chosen in that it provides the means to spot mask selected areas with the convenience of a hand-held tool. The paint mask solid as described herein has been found to provide a most convenient protective coating when used prior to brush-painting window mullions and frames. Changes may be made to modify the constituents of the masking solid and various additives may be incorporated into the paint mask composition to impart desirable attributes without altering the essential advantages offered by employing a paint mask in dispensable solid iPorm and its unique method of direct mask application.
The present invention has proven effective in coating and protecting materials other than glass, where the protected surface: offers frictional resistance to the solid coating material dragged upon its surface sufficient to shear off a layer of the coating material. Such materials include metal, wood, painted surfaces, plastic and similar surfaces that permit the shear-off and dispensing of a paint masking film.
Though the present invention has been described above with reference to a preferred embodiment, those skilled in the art will recognize that changes and modifications may be made in this preferred embodiment of both the unique solid masking tool and novel process without departing from the scope of the present invention. Rather any and all changes and modifications, which a.re obvious to those skilled in the art, are intended to be included within the scope of the present invention.
In drawings which illustrate the embodiments of the invention, Figure I is an elevation partly in section of one embodiment. Figure 2 is a top view of this embodiment.
The hand-held tool illustrated comprises a solid paint masking stick material C housed in a tubular container B wherein the solid masking material is advanced through the open-end of the tube as shown in a top view in Figure 2 by a plunger E so that the masking material may be robbed directly onto the surface to be protected. The container's cap A serves to seal the masking contents housed within the container, while its angled tip forms a scraper which may be used to remove paint drips on the surface which are more difficult to remove.
