1. Field of the Invention
Enhancement of surfaces that may be permanently or temporarily re-designed, decorated, and/or re-colored with a design device is disclosed herein.
2. Description of the Background of the Invention
Improving the aesthetics in homes has long been practiced by many consumers. There is a plethora of home products and techniques for cleaning surface areas of soft surfaces such as carpets, rugs, draperies, curtains, upholstery, and the like. However, for more sullied and/or worn surfaces, subtractive processes (for example, a process that chemically or physically removes something from the carpet, such as cleaning or shaving) cannot truly restore the surface to its original state; this is often very frustrating for consumers. Oftentimes, spots and stains reappear after treatment.
Additive processes (for example, a process that layers, covers, or masks something undesirable underneath) and techniques for improving the aesthetics of surfaces include painting, faux painting, stenciling, bordering, wallpapering, tiling, wainscoting, paneling, decorative plastering, adding appliqués (for example, pictures, cut-outs, stickers, or the like), laminating, and molding (for example, crown, shoe, and chair) are also known. However, these products and techniques have not been applied to soft surfaces such as carpets, rugs, draperies, curtains, upholstery, and the like.
According to one aspect of the present disclosure, a kit for applying a design to a desired surface includes a low-slip stencil that inhibits lateral movement of the stencil on the desired surface and a first dispensing device comprising a colorant composition that comprises a liquid carrier and particles. At least one particle comprises a homogeneous mixture of a colorant and a polymer.
In another aspect of the present disclosure, a kit for applying a design to a desired surface includes a low-slip stencil that inhibits lateral movement of the stencil on the desired surface, the stencil including one or more layers and a bottom surface comprising an adhesive. The kit further includes a first dispensing device containing a composition, the composition including a liquid carrier, at least one particle comprising a homogeneous mixture of a colorant and a resin, the resin comprising at least one of an acrylic, an acrylic latex, a polyester, a urethane, or an epoxy, and an optional additive; and an optional second dispensing device containing a sealant composition.
In still another aspect of the present disclosure, a kit for applying a design to a desired surface includes a low-slip stencil having a bottom surface that has an average static coefficient of friction of about 0.3 to about 0.8 and an average kinetic coefficient of friction of about 0.2 to about 0.8 as measured against a bottom surface of another surface having the same bottom surface as the fourth layer. The bottom surface inhibits lateral movement of the stencil on the desired surface. The further includes a container including a colorant composition that includes: a) decor particles having a homogeneous mixture of a colorant and a resin selected from the group consisting of an acrylic, acrylic latex, a polyester, a urethane, and an epoxy; b) an emulsifier, and c) a liquid carrier.
The present disclosure is directed to compositions, methods, apparatuses, kits, and combinations, for permanently or temporarily re-designing, decorating, and/or re-coloring a surface. While several specific embodiments are discussed herein, it is understood that the present disclosure is to be considered only as an exemplification of the principles of the invention, and it is not intended to limit the disclosure to the embodiments illustrated.
For example, a composition useful in the present disclosure includes a décor product that is formulated to be applied and affixed to a surface. The décor product may also be utilized in the form of a kit or in conjunction with a design device, such as a stencil, to control the application of the décor product to create, for example, a pattern on the surface.
Any surface is contemplated to which the décor product may be applied and/or affixed, including, for example, soft surfaces such as carpets, rugs, draperies, curtains, upholstery, and the like. In addition, the décor product may be applied to hard surfaces as well, including, for example, wood, metal, ceramic, glass, a polymer, a hard floor tile, a painted surface, paper, masonry material, rock, a fiber/composite material, rubber, concrete, and the like. It is contemplated that the décor product may be applied to any prepared surface, including, for example, pre-dyed, post-dyed, pre-manufactured, and post-manufactured surfaces. Further, the décor product may be applied during the manufacturing process of a particular good or object that includes a surface in which the décor product may be applied. Surfaces to which the décor product may be applied and/or affixed may be substantially dry, substantially wet, moist, or humid depending on the particular décor product utilized. Further, a décor product of the present disclosure may be applied to a substantially flat, smooth, and/or level surface or any other surface including rough, bumpy, non-smooth, stepped, sloped, slanted, inclined, declined, and/or disturbed surfaces.
Examples of carpets to which the décor product may be applied and/or affixed include modular tiles and panels such as Milliken LEGATO®, Milliken TESSERAE®, INTERFACEFLOR™, Tandus/C&A floorcovering, and from manufacturers such as Mohawk Industries and Shaw Industries, Inc. Additional examples of carpets include broadloom carpets, cut pile (velvet/plush, Saxony, frieze, shag), loop pile (level loop, multi-level loop, and Berber), and cut and loop pile (random sheared and tip sheared) carpets. Additional examples of soft surfaces to which a décor product may be applied and/or affixed thereto include, for example, area rugs (hand woven or machine woven), draperies, curtains, upholstery, and cellulosic materials, among others. Constituent materials of candidate soft surfaces include, for example, natural fibers such as wool and cotton, or synthetic fibers such as nylon 6, nylon 6-6, polyester, polypropylene (olefin), and acrylic, among others.
Decor products of the present disclosure may be formulated, designed, produced, manufactured, applied, removed, and/or packaged by any formulaic, chemical, and/or physical preparation appropriate for the specific embodiment desired, as would only be limited by the inherent nature of the constituent ingredients. Illustrative formulations of the décor products include a solid that may be dissolved or dispersed in a liquid to make a liquid-based décor product, a liquid carrier, an emulsion, a suspension, a colloid, a sol, a dispersion, a solution, a gel, a paste, a foam, a powder, a spray, a tablet, a solid, a gas, a diluent such as water or other solvent, an aerosol, and combinations thereof. Examples of chemical preparations include polyester polymerizations, latex aggregation, chemical milling, and microencapsulization, and other methods known to those skilled in the art. Physical preparation may consist of physically grinding the décor product ingredients or other means known to those skilled in the art. Decor products may be either synthesized from a molecular route, in which polymer resin molecules incorporate colorants, dyes, and/or pigment particles at the molecular scale, such as in the method of manufacture used in chemically prepared toners, or the resin and pigment particles may be physically blended together and crushed to appropriate size by mechanical means known to those skilled in the art.
Examples of applicators and/or dispensers of the décor product of the present disclosure include, for example, an intermittent pressurized sprayer (such as PULL 'N SPRAY® liquid applicator marketed by The Scotts and Miracle-Gro Company), an actuator spray bottle, a trigger sprayer, a mechanical spray bottle, a pump and/or pump system, a liquid refill containing the décorproduct for a pressurized air chamber, an aerosol barrier pack containing the décorproduct with a driving chamber (with a propellant, for example, carbon dioxide or a hydrocarbon), and a liquid or gel chamber for containing the décorproduct where use would allow pressurized spraying with reduced propellant release to the atmosphere or room being decorated by the user. Other useful sprayers include those disclosed in, for example, U.S. Pat. No. 6,872,444. Yet other dispensers useful in the present invention include those disclosed in, for example, U.S. Ser. No. 12/152,311, filed May 14, 2008.
A stencil may be used to assist in the application of the décorproduct to a surface for the purpose of creating, for example, a pattern on the surface to enhance the aesthetic effect of the décorproduct. Possible décorproduct patterns on surfaces contemplated in the present disclosure include any and all images, patterns, shapes, and/or designs. Preselected or random patterns may also be imparted to a surface using an inherent dispersal pattern from a décorproduct applicator with or without movement of the applicator over a selected surface during application of the décor product. For example, by using a spray applicator with a cone-shaped dispersal pattern, a user may choose to apply discrete spots and/or circles having diameters that are varied by varying the distance from which the applicator is held from the surface during application of the décorproduct. Further, a user may move the applicator during application of the décorproduct over the surface in a predetermined or random pattern to achieve a predetermined or random pattern on the surface. As such, preselected patterns and/or random patterns may be imparted to a surface with or without a design device.
Stencils or other design devices contemplated for use in the present disclosure may be designed, constructed, shaped, and/or reshaped, in a predetermined, ordered, disorganized, and/or random manner by means of laser, knife, die cutting, and/or any other appropriate means as determined by the nature of the stencil material (for example, hardness or softness of the stencil materials) to render a predetermined, ordered, disorganized, and/or random shape that allows a predetermined, ordered, disorganized, and/or random deposition of at least a visual design by introducing a décorproduct on a surface. The stencils may further be laminated and have additional layers applied thereto post-construction and/or post-designing.
The present disclosure also provides kits that contain one or more components herein described, including, for example, a design device and/or a décor product that may be substantially removed from a surface prior to being affixed thereon. A set of instructions may also be included in the kit instructing the user how to apply the design to a soft surface such as a carpet. The kit may further comprise one or more application devices for transferring the décorproduct to the carpet and/or one or more fixative devices for affixing the décorproduct to the surface. In addition, the kit may include a protective covering for protecting the décorproduct after it has been applied to the carpet, especially while it is drying. The kit may further include an iron screen that is used to provide a user with an indication of what areas of the décor product have already been ironed or affixed.
As an example, the kit may be provided having one or more stencils, for example, five stencils, a décorproduct, an application device such as a sprayer, an affixing device such as a heating device (for example, an iron or a radio frequency emitting device), and/or a set of instructions. The kit may also include a system to identify, choose, make, modify, and/or prepare the surface on which the décorproduct is to be applied.
A cross-section along the line A of an embodiment of the stencil 2210 is shown in
When the stencil 2210 is placed on a surface 2228 (for example, a floor and/or a wall), the various layers that comprise the stencil 2210 may be configured to inhibit and/or prevent excess decor product that is applied to the stencil 2210, but does not pass through the cutouts, from reaching the surface 2228. The absorptive layer 2230 acts as a material containment layer that absorbs the excess decor product. For example, one embodiment of the stencil 2210 comprises an absorptive layer 2230 that is able to absorb an amount of liquid equal to several times the weight thereof, such as between about eight to about eleven times the weight of the absorptive layer 2230. The absorptive layer 2230 may be manufactured from, for example, a combination of woven and non-woven, natural and synthetic materials including pulp, paper, synthetic fibers, cotton, cotton fabrics, rayon, polyester, lycocell, lyocel, polypropylene, etc. The absorptive layer 2230 in some embodiments of the stencil 2210 may comprise, by weight, from about 50% to about 90% rayon, from about 60% to about 80% rayon, from about 50% rayon, from about 60% rayon, about 70% rayon, about 80% rayon, or about 90% rayon. Some embodiments of the stencil 2210 comprise an absorptive layer 2230 that may comprise from about 10% to about 50% polyester, from 20% to about 40% polyester, about 10% polyester, about 20% polyester, about 30% polyester, about 40% polyester, or about 50% polyester. In some embodiments, the absorptive layer 2230 may comprise a blend that has a greater portion, by weight, of polyester than rayon. Other embodiments of the absorptive layer 2230 may include a blend having about equal portions, by weight, of rayon and polyester. Illustratively, the absorptive layer 2230 comprises about 70% rayon and about 30% polyester by weight, or about 60% rayon and about 40% polyester by weight, or about 50% rayon and about 50% polyester by weight, or about 40% rayon and about 60% polyester by weight. In another embodiment, the absorptive layer 2230 comprises a spunbond textured (for example, having a 3 mm dot pattern) blend of about 70% rayon (for example, lyocel, manufactured by Lenzing Inc., under the trademark TENCEL®, or other cellulose fabric that is obtained by an organic solvent spinning process) and about 30% polyester by weight. Other components, for example, anti-static materials, may also be incorporated as desired into the absorptive layer 2230 in addition to the woven and/or non-woven materials.
The top surface 2238 of the absorptive layer 2230 may be embossed to reduce overspray that may be generated when a liquid is sprayed thereon. The top surface 2238 may be embossed using a process compatible with the materials that includes the absorptive layer 2230 including, for example, hydro-embossing, heat embossing, and/or mechanical embossing (for example, stamping).
In this embodiment, the attachment and barrier layer 2232 enables attachment of the absorptive layer 2230 to the structured layer 2234. The attachment and barrier layer 2232 may be an adhesive material that bonds the absorptive layer 2230 to the structured layer 2234. Alternately or in addition to, the attachment and barrier layer 2232 may include a moisture resistant adhesive and/or a moisture resistant polymer such as polyethylene. In such cases, the attachment and barrier layer 2232 may both bond the absorptive layer 2230 to the structured layer 2234 and/or provide a liquid impermeable layer by providing a barrier that prevents or inhibits liquids absorbed by the absorptive layer 2230 from being released to the structured layer 2234.
A material that combines together the absorptive layer 2230 and the attachment and barrier layer 2232 may also be used. An example of such a material includes the commercially available GOTCHA COVERED® drop cloth by Kimberly-Clark Corp.
If desired, the structured layer 2234 may provide rigidity to the stencil 2210. The structured layer 2234 may also form a moisture barrier that blocks or retards the release of liquids absorbed by the absorptive layer 2230 to the surface 2228. The structured layer 2234 may be comprised of a cellulosic material such as cardboard or paper, polymer-based films such as MYLAR®, a polymer-based foam, a foil film, semi-stiff nonwoven (for example, needle punched) materials, poly-coated nonwoven materials, corrugated board, and combinations thereof In some embodiments, paperboard between about 12-point to about 22-point may comprise the structured layer 2234. For example, 18-point paperboard may be sufficiently rigid for use as a material for the structured layer 2234. For certain applications, described below, the material selected for the structured layer 2234 may allow the stencil 2210 to be folded or to be cut into a desired shape using common tools such as a utility knife or scissors.
In yet other embodiments, the low-slip and flatness coating layer 2236 allows the stencil 2210 to lay flat and remain static on the surface 2228 but has sufficient slip to allow the stencil 2210 to be repositioned by a user by sliding across the surface 2228, as necessary. For example, the low-slip and flatness coating layer 2236 has coefficient of friction properties that prevent or inhibit lateral movement of the stencil 2210 against the surface 2228 sufficient for a user to apply the stencil to the surface and readjust the location thereof as needed, but also to allow the application of the décorproduct thereto without the stencil moving inappropriately before, during, and/or after the application of the décorproduct to the surface. Illustratively, the low-slip and flatness coating layer 2236 is a coating that is applied to the bottom surface of the structured layer 2234. The coating may comprise, for example, a wax, a polymer (for example, polyethylene), a thermoplastic, silicone, and/or polytetrafluoroethylene. Further examples of coatings useful in the present disclosure include water-based coatings, water-based emulsions and dispersions, solvent-borne dispersions, and micronized powders for paper, film and foil packaging, such as those available from Michelman, Inc., Cincinnati, Ohio, including, for example, Michem® Prime, a ethylene-acrylic acid co-polymer dispersion, MILLWHITE™, a non-waxable white coating, SOFTAK®, a water-based coating to increase skid angle, and WAX DISPERSION 40®, a solvent dispersion of paraffin wax. Combinations of the above coating may also be used to achieve the desired slip resistance or static or kinetic coefficient of friction properties.
In one embodiment, the low-slip and flatness coating layer 2236 may comprise a low-tack adhesive that is applied to the bottom surface of the structured layer 2234. In some embodiments, the low-slip and flatness coating layer 2236 may also be liquid impermeable and provide a barrier that prevents or inhibits liquids absorbed by the absorptive layer 2230 from being released to the surface 2228 on which the stencil is placed. For example, by including a moisture resistant material in the low-slip and flatness coating layer 2236.
In one embodiment, a stencil 2210 includes a structured layer 2234 of 16-18 point paperboard and a low-slip and flatness coating layer 2236 formed by coating the structured layer 2234 with about 7 to about 10 pounds per 100 square feet of mirror finished polyethylene. In other embodiments, a low density polyethylene may be used. In still other embodiments, a coated paperboard may be used whereby the paperboard may supply the structured layer 2234 and the coating may supply the low-slip and flatness coating layer 2236. Examples of such coated paperboard products include polyethylene extrusion or wax coated CARTONMATE® bleached boards or coated recycled boards (for example, ANGELCOTE®) manufactured by Rock-Tenn Company, Norcross, Ga.
Illustratively, the bottom surfaces 2240 of a plurality of such stencils (for example, the bottom surfaces of the low-slip and flatness coating layers 2236) may have static coefficients of friction that range from about 0.4 to about 0.7 and kinetic coefficients of friction that range from about 0.3 to about 0.5 when measured relative to a bottom surface of another stencil in the manufacturing (grain) direction of the paperboard. The bottom surface 2240 of some embodiments of the stencil 2210 may have a static coefficient of friction from about 0.3 to about 0.8 and a kinetic coefficient of friction from about 0.2 to about 0.6. Static and kinetic coefficient of friction may be determined using methods known in the art including, for example, standardized method such as the ASTM D-2047 or using a frictionometer as known by those skilled in the art.
When measured relative to the bottom surface of another stencil having the same or identical bottom surface in the cross direction of the paperboard, the bottom surface 2240 of an embodiment of the stencil 2210 may have a static coefficient of friction that ranges from about 0.4 to about 1.0, from about 0.3 to about 1.1, or from about 0.2 to about 1.2. Some embodiments of the stencil 2210 may have a bottom surface 2240 that has a kinetic coefficient of friction that ranges from about 0.3 to about 0.9, from about 0.2 to about 1.0, or from about 0.1 to about 1.1.
Some embodiments of the stencil 2210 may have a bottom surface 2240 with an average static coefficient of friction that range from about 0.3 to about 0.8, from about 0.4 to about 0.7, or from about 0.5 to about 0.6. The average kinetic coefficients of friction of the bottom surface 2240 of some embodiments of the stencil 2210 may range from about 0.4 to about 0.6, from about 0.3 to about 0.7, or from 0.2 to about 0.8.
In some embodiments, the layers that comprise the stencil 2210 have substantially identical planar dimensions. In other embodiments, adjusting the sizes of the individual layers that comprise the stencil may retain properties of the stencil (for example, absorbency and rigidity) while optimizing other aspects (for example, material cost) of the stencil. For example,
It should be apparent that the layers that comprise the stencil 2210 do not have to have identical thickness. For example, the absorptive layer 2230 may be thicker than the structured layer 2234, and each of these may be thicker than either the attachment and barrier layer 2232 or the low-slip and flatness coating layer 2236. The thickness of the individual layers and the stencil 2210 as a whole may be optimized according to the environment and application in which the stencil 2210 may be used and/or to the specific composition that is being applied with the stencil 2210 and the liquid content thereof For example, in some applications, the thickness of the stencil 2210 may be minimized to reduce bulk while maintaining the absorptive properties and structural integrity thereof In other applications, the thickness of the stencil 2210 may not matter and production cost may be optimized. In some embodiments, the thickness of the structured layer 2234 may be from about 0.011 inches to 0.025 inches thick, from about 0.013 to about 0.023 inches thick, from about 0.015 to about 0.021 inches thick, from about 0.013 to about 0.015 inches thick, about 0.014 inches thick, about 0.016 inches thick, about 0.018 inches thick, about 0.020 inches thick, or about 0.22 inches thick. In some embodiments, the thickness of the attachment and barrier layer 2232 and/or the low-slip and flatness coating layer 2236 may be from about 0.0002 inches to 0.0008 inches thick, from about 0.0004 inches to about 0.0006 inches thick, about 0.0003 inches thick, about 0.0005 inches thick, or about 0.0007 inches thick.
It is contemplated that any of the layers that comprise the stencil 2210 may be liquid impermeable and prevent or reduce passage of liquid deposited onto the surface of the stencil 2238 from migrating to the surface 2228 onto which the stencil is placed. It is further contemplated that any of the layers that comprise the stencil 2210 may provide structure to the stencil. In addition, any of the layers of the stencil 2210 may have absorptive properties and may provide containment of materials deposited onto the surface of the stencil 2238.
Similarly, the portion of the weight that the individual layers of a stencil 2210 comprise may not be identical. For example, in one embodiment of the stencil 2210, the absorptive layer 2230 comprised approximately 25% of the weight of the stencil 2210 and the structured layer 2234 comprised approximately 75% of the weight of the stencil 2210. In some embodiments, the attachment and barrier layer 2232 and/or low-slip and flatness coating layer 2236 may comprise from about 0.5% to about 1.5% of the total weight of the stencil 2210 or, in other embodiments, may comprise less than about 1% of the total weight of the stencil 2210.
Additional layers may be incorporated into the stencil 2210. For example,
The additional support layer 2242 may also be positioned on the top surface 2238 of the absorptive layer 2230. For example, an additional layer 2242 comprising threads may be attached to the top surface 2238 of the stencil 2210. The additional support layer 2242 may be attached either during the manufacture of the stencil 2210 and/or as an additional post processing step. Similarly, the additional support layer 2242 may be added to the bottom surface 2240 of the stencil 2210.
Two or more additional support layers 2242 may also be used. For example, a first additional support layer 2242 may be situated between the absorptive layer 2230 and the attachment and barrier 2232 layer and a second additional support layer 2242 may be situated between the structured layer 2234 and the low-slip and flatness coating layer 2236. In such embodiments, the first and second additional support layers 2242 may be identical or different. For example, the first additional support layer 2242 may be comprised of threads and the second additional support layer may comprise a mesh.
Although not shown, in some embodiments, a web of material used for the absorptive layer 2230 is laminated with the material used for the attachment and barrier layer 2232 to form a first laminated web. Similarly, a web of the material used for the structured layer 2234 is coated with the material used for the low-slip and flatness coating layer 2236 to form a second laminated web. Thereafter the first and second laminated webs may be introduced into a production line that includes a bonding unit for joining the first and second laminated webs together into a web of stencil material. The bonding unit may include a heating unit to activate the adhesive in the attachment and barrier layer 2232. Alternately, the bonding unit may include a pressure unit that activates the adhesive. A combination of heat and pressure may also be used. Other ways of joining the first and second laminate webs to form the web stencil material known in the art may be used. For example, an embodiment of the stencil 2210 comprises a non-woven absorptive layer 2230 laminated (for example, via poly coating, extrusion application, or extrusion lamination using molten polymer) using an attachment and barrier layer 2232 to a 16-18 point paperboard structured layer 2234 substrate that is poly-coated to form a low-slip flatness layer 2236 on an exterior surface. Such embodiment may provide a liquid barrier and a degree of surface tension when placed on a soft surface to reduce movement of the stencil during application of the decor product. The production line may include embossing units to emboss the top surface of the web of stencil material (for example, if the absorptive layer had not been embossed prior to forming the first laminated web). Die cutting units in the production line may be used to form regularly spaced cutouts in the web of stencil material and sheeting units may be used to cut the web of stencil material into individual stencils.
In some embodiments, a roll of uncoated paperboard that comprises the structured layer 2234 may be extrusion laminated to a roll of non-woven material, which comprises the absorptive layer 2230, using molten polyethylene, which comprises the attachment and barrier layer 2232. The laminated material may thereafter be wound up onto a master roll. The master roll may coated on the paperboard side with molten polyethylene, which forms the low-slip and flatness layer 2236, and the coated material may be wound up onto a roll to form a coated master roll. The coated master roll may thereafter be cut into stencil sized sheets (for example, about 20-inches square) and stacked in columns. The stacked columns of cut sheets may thereafter be cut, for example on a flat bed die-cutting machine, to form the cutout portions of the stencil. In other embodiments, the coated master roll may be cut into sheets larger than the stencil and such sheets may be later trimmed to a final size.
Further embodiments of the present disclosure may incorporate value adding chemistries including powder coatings, toner and/or ink chemistries, carpet stain removers and/or maskers, odor eliminators and/or absorbers, bleaching agents. Compositions, methods of carpet stain removing and/or masking, methods of composition affixation, design aids, including stencils, and dispensing devices useful in the present disclosure include those disclosed in U.S. Pat.
