ABSTRACT:
FIELD OF THE INVENTION
This invention relates to a tool for removing adhesive films from substrates. More particularly, the invention relates to a scraper adapted to remove adhesives, adhesive labels, tags, cured and uncured polymer films, such as sealants, paints, and the like from a substrate.
BACKGROUND OF THE INVENTION
Many products are purchased by consumers having adhesive tags, labels and other materials attached to them. Additionally, some products intentionally or unintentionally, have areas of adhesive, paint, pigment, or other coatings on them which must be removed. Removal of such tags, materials and other blemishes from products, especially smooth surfaced or delicate products, has been a problem for many people in the past. This is true for both consumers and businesses.
A tag on a product is sometimes removed by the consumer by a using a fingernail. This often results in incomplete removal of the tag and often leaves a residue of adhesive in place. Sometimes, consumers will attempt to clean paint splatters or adhesive residues from products with a paper towel or sharp implement and water, rubbing alcohol, acetone, other solvents, or the like. The adhesive is sometimes slightly softened by the alcohol and retains portions of the paper towel on the substrate intended to be cleaned. If one is not succeeding with a fingernail or paper towel, one will often turn to a kitchen knife or something more aggressive and dent, scratch or otherwise damage a product or substrate. One often creates a bigger mess than one had to begin with.
People often use some kind of a solvent to remove paint splotches, adhesive marks, tags, stickers, and the like. People also often use scrapers of one kind or another to do this job. However, the two items are often stored separately leaving the consumer to use only one of the two, the solvent or the scraper, because they cannot find the other.
Thus, removal of paint spots, adhesive residue, labels, stickers, and the like from substrates in the past has been a frustrating proposition for most people.
SUMMARY OF THE INVENTION
The present invention provides a tool for removing adhesive, paint splatters, adhesive tags, stickers, decals and/or polymer film from a substrate, the tool comprising a bottle cap having gripping portion and a blade portion, the blade portion having a sharp corner, a straight portion and a rounded portion.
Further in accordance with the invention, the cap is fabricated from a polymeric material which is relatively stiff and the blade is tapered from its base to its leading edge so that a small amount of flexibility with elastic recovery is provided at the leading edge of the blade.
Yet further in accordance with the invention, the cap can be firmly attached to a solvent containing bottle allowing one to use the cap as a tool either on the bottle or off the bottle for working in tight areas.
Still further in accordance with the invention, the tool acts both as a scraping tool and as a closure for a solvent bottle whereby the tool will normally be kept with the solvent bottle and is readily available for use.
Still further in accordance with the invention, the base of the tool provided with ridges around its periphery making the tool easily grippable either on or off the bottle.
It is principal object of the present invention to provide an adhesive removing tool which will cleanly and easily remove adhesive, paint splatters, adhesive tags, and the like from a substrate without damaging the substrate.
It is another object of the present invention to provide an adhesive removing tool which can be used when attached to a bottle of adhesive remover or separately from the bottle of adhesive remover.
It is yet another object of the present invention to provide an adhesive removing tool that can be used in restricted or awkward locations.
It is still another object of the present invention to provide an adhesive removing tool having a scraping edge with a variety of curvatures whereby adhesive, paint, labels, and the like can be removed from substrates with a variety of configurations.
It is another object of the invention to provide an adhesive removing tool which can remove blemishes of irregular shape and tenacious composition.
It is another object of the present invention to provide an adhesive remover tool which is inexpensive to manufacture, easy for the user to maintain, and efficient in use.
