Definitions

  • the present invention relates generally to chewing gum. More specifically, the present invention relates to methods and compositions for removing chewing gum from surfaces.
  • Chewed gum is easily disposed of in the wrapper that initially houses the chewing gum.
  • chewed gum can be disposed of in other substrates by wrapping the substrate around the chewed gum.
  • chewing gum can be easily disposed of without creating any problems
  • chewing gum that is improperly disposed of can create environmental concerns.
  • the improper disposal of chewing gum i.e., expectorating of chewing gum on a sidewalk, floor, carpeting, or like area
  • Typical chewing gum due to its formulation, after it is chewed, has adhesive-like characteristics. Therefore, chewed gum can stick to surfaces to which it is placed. As the gum residue ages, it becomes hard and brittle making it difficult, if not impossible, to peel away from the surface to which it is attached. Unfortunately, many consumers do not properly dispose of chewed gum.
  • chewed gum is expectorated on sidewalks and like surfaces, stuck on walls, masonry, furniture, carpeting, or other structures. This thereby necessitates the manual removal of stuck chewing gum using a scraping device or other means.
  • a scraping device or other means it may not be possible, using heretofore practiced methods, to easily remove all of the chewed gum from the structure to which it is stuck. Even if the gum is removed, typically, the process of removal will result in a stain or other mark on the surface.
  • a further problem is that if chewed gum is deposited on the ground, sidewalk, or other surface and is stepped on, the chewed gum can attach to a person's shoe. Chewed gum can then be transferred from the person's shoe to another surface such as a upholstery, carpet, or clothing. Chewed gum, due to its adhesive nature, using current prior art methods, may be difficult if not impossible to remove from carpet-like surfaces or clothing. Methods that have been proposed and attempted to remove chewing gum include techniques, such as freezing the gum with freon, propane, and butane. However, such methods are environmentally unsafe. Professional cleaners attempt to remove chewing gum from clothing using solvents, such as petroleum distillates. However, these compounds are flammable or combustible and can be toxic.

  • Pursuant to the present invention methyl salicylate is used to remove the chewing gum from the surface.
  • the methods of the present invention are safe and effective ways to remove chewing gum from surfaces.
  • Methyl salicylate is commonly referred to as oil of wintergreen. It is a readily available composition to consumers (as oil of wintergreen or in pain relief liniments, etc.); the product is available at hardware, drug, and grocery stores. Methyl salicylate is not flammable, combustible, or otherwise harmful to the environment ' . In this regard, it is an "environmentally friendly" composition. It has been discovered that methyl salicylate is a potent gum plasticizer/softener. Because methyl salicylate does not dissolve or soften fabrics including such compositions as nylon, it can be used to safely remove gum from fabrics.
  • methyl salicylate emulsifies easily with soap and water and has an agreeable odor, it can be used to remove chewing gum and is easily removed from the surface without an offensive odor, stain, or residue.
  • methyl salicylate is used to remove chewing gum effectively from any surfaces. Even though, as chewing gum residue ages, the gum residue becomes hard and brittle making it difficult, if not impossible, to peel away, methyl salicylate has been found to soften and plasticize the gum sufficiently so that it can be easily removed from surfaces including fabrics and carpet.

  • clockwise and counterclockwise twisting motions are used. In this regard, first a clockwise twist (or counterclockwise twist) of the chewing gum is performed and then a counterclockwise (or clockwise) twist of the chewing gum residue is performed. The twisting motion should remove even the most difficult residue chewing gum from fabrics and carpeting.
  • plastics can be used to create the flexible sheets of material.
  • a low density polyethylene or low density polypropylene blend of plastic is used to create the flexible sheets of plastic.
  • other plastic materials can be used including ethylvinyl acetate, polyvinyl chloride, polyvinylidene chloride and the like. What is important is that the sheets are flexible.
  • the plastic material is also clear so that it is easily visible. This will allow one to easily determine the amount of chewing gum removed.
  • the flexible nature of the plastic sheets allows the material to be sufficiently pliable to penetrate small spaces where the chewing gum may adhere. This is especially advantageous for removing gum from carpeting.
  • the plastic sheets are hydrophobic, the sheets will attract the rubber/fat/resin matrices of the chewing gum residue increasing the effectiveness of the method. It is envisioned that in removing chewing gum from carpeting, the use of flexible sheets may be a preferred method. On the other hand, when removing chewed gum from concrete or clothing, flexible sheets may not be required.
  • a further advantage of the plastic matrix of the sheets is that they will not fall apart in a manner similar to wax paper or paper towels.
  • the sheets thereby provide a convenient substrate for removing and disposing of chewed gum.
  • An additional advantage of using plastic sheets is that they are readily available to consumers. In this regard, consumers can use a variety of different products for obtaining the plastic sheets of material, e.g., plastic bags that are used for lunch and storing food products.
  • EXAMPLE NO. 1 Chewing gum was chewed for twenty minutes and then forced into a carpet sample to create a gum crater. After aging the gum for two hours, approximately 70 to 85% of the gum cud was removed with polyethylene sheets. The gum cud was then heated with a hair blow dryer and another 10% was removed with the polyethylene sheets. The carpet was then washed with soap and water using a brush. The residue gum and carpet was treated with the polyethylene sheets again, dried with a towel, and allowed to air dry. There were small bits of gum left in the carpeting but approximately 90 to 95% of the gum was removed. EXAMPLE NO. 2 Control - The cud was embedded into the carpet but after aging it for two hours there was no attempt to remove it. EXAMPLE NO. 3
  • Chewing gum was again chewed for twenty minutes and then forced into an identical carpet sample as in Examples 1 and 2 to create a gum crater. After aging the gum for two hours, approximately 70 to 85% of the gum cud was removed with the polyethylene sheets. Then 1 ml of methyl salicylate was applied to the gum cud. After waiting 2 minutes, the gum was pulled again using the polyethylene sheets in a circular clockwise, then counter-clockwise motion. Soap and water was applied and then the carpet was brushed, dried with a towel, and treated with more polyethylene sheets. There was 100% gum removal in 5 minutes.
  • EXAMPLE NO. 4 Chewing gum was again chewed for twenty minutes and then forced into a carpet sample to form a crater. After aging for three days, the gum cud was treated in the same way that the sample in Example 3 was treated. The only difference was that a hair dryer was used to heat the gum cud before the methyl salicylate was applied. There was 100% gum removal. Summary
  • Goo Gone ® Magic American Corp., Cleveland, Ohio, containing 95% petroleum distillates
  • Goo Gone ® instructions did not include a warning to wear gloves, yet when it was applied, it removed the oil and moisture from the hands and caused irritation. This material is flammable and combustible although there is no warning for these two attributes.
  • Citrusolv ® from Texon, Cicero, IN, a flammable liquid, was also used to remove four day old chewing gum from carpet but 4-6 ml of Citrusolv ® had to be used and it dissolved the adhesive which holds the backing of the carpet to the carpet fibers.
  • EXAMPLE NO. 8 The following Tables (I-III) set forth test results of the present invention vis-a-vis other methods of attempting to remove chewed gum from a variety of materials.
  • PEEL OFF PEEL OFF. WITH REMOVAL DIFFICULTY + PURPLE STAIN
  • Methyl salicylate removes 100% cud (peels right off after 1-2 minutes of treatment) and washes off with slight wintergreen odor.
  • Methyl salicylate completely removes gum cud residues from synthetic and synthetic/cotton blends without undesirable effects cheap fabrics might experience some bleeding. Freezing can damage fabric upon removal of cud and should not be recommended for cud removal. Cud age (over 3 days) does not effect methyl salicylate effectiveness.

Abstract

La présente invention concerne un procédé, sans flamme ni combustion, de décollage des chewing-gums mâchés adhérant à des surfaces (notamment les tapis et moquettes, le ciment ou les vêtements). Selon le procédé, le décollage du chewing-gum se fait avec du salicylate de méthyle, ledit salicylate de méthyle s'étant avéré capable de décoller efficacement le chewing-gum des surfaces sans laisser de taches sur les tissus (tels que tapis et moquettes ou vêtements) auxquels il peut adhérer. Le procédé de décollage du chewing-gum mâché consiste, selon la présente invention, à mettre en contact le chewing-gum avec une composition intégrant du salicylate de méthyle, puis à décoller le chewing-gum.
