1. Field of the Invention
The present invention relates generally to erasers and more specifically to erasers in the form of silicone rubber bands and/or silicone rubber jewelry, namely bracelets.
2. Background Art
Erasers and the like have been known. Erasers are typically constructed of rubber or synthetic material that allow a user to erase a mark, such as a pencil mark, ink mark, the like, or indicia from a surface. Erasers typically have a rubbery consistency, come in a variety of colors, and are comprised of a single layer of material, such as synthetic rubber, plastic or gum-like materials, synthetic soy-based gum, and may also contain vinyl and pulverized pumice.
Edward Naime, an English engineer, is credited with creating the first rubber eraser, using natural rubber, in 1770. However, such natural rubber erasers were not durable, were perishable, and would go bad over time. Erasers came into common use after Charles Goodyear discovered the process of vulcanization in 1839, a method that cured rubber and made it durable. Hymen Lipman received the first patent on Mar. 30, 1858 (U.S. Pat. No. 19,783) for attaching an eraser to the end of a pencil; however, the patent was later invalidated.
Erasers come in several shapes and sizes; the more common erasers come attached to pencils, conical cap erasers that may be slipped onto the ends of pencils, block and wedge erasers that may be rectangular or block shaped, and barrel erasers contained in a barrel of a retractable cylinder. Novelty erasers are also available that have a variety of colors, shapes, and designs that are primarily intended for their decorative nature more than practical use.
Erasers that may be used for instructional purposes and/or entertainment and that may be used practically for the function of erasing are necessary. Such erasers should have the added convenience and capability of being worn, as jewelry, on or close to the human hand and therefore close to the writing utensil providing marks that may need erasing.
The solution for this lack of convenience and practicality is the invention of an “eraselet,” an eraser made of silicone rubber with an open circular form that may be worn loosely, as jewelry, around the human wrist.
U.S. Pat. No. 6,547,465 (Rago, et al.) discloses a pencil that has a fixed non-replaceable eraser and a moveable sleeve.
U.S. Pat. No. 5,709,491 (Yeh) discloses a tubular eraser for erasing ink or pencil marks comprising an elongated body of a rubber material.
U.S. Pat. No. 4,899,419 (Saleen) discloses a pencil eraser assembly having elongated hollow eraser sleeve formed to align in elemental parallel spaced relationship with both a frustum shaped segment and a portion of a cylindrical barrel segment of a pencil.
U.S. Pat. No. 4,689,858 (Barber) discloses a fastening device comprised of an elastic band permanently attached at one end either in a utilitarian sense or in a static sense and temporarily attached at the other end, of which is adjustable by pulling on this unattached end, to a simple clasp with holes of a similar diameter as the elastic band and of which secures the band to a specific total circumference and range of tensile strength by the force of friction generated between the band and clasp.
For the foregoing reasons, there is a need for silicone rubber erasers with the added convenience and capability of being worn, as jewelry, on or close to the human hand and therefore close to the writing utensil providing marks that may need erasing.
The present invention is directed to an eraser in the form of a silicone rubber band and/or silicone rubber jewelry, namely a bracelet.
Eraselets®, erasers produced in the form of a circular, silicone rubber band and/or silicone rubber jewelry, have elasticity as to not be constricted in form to assist in pulling the Eraselet® over the hand to the wrist were such erasers should be worn and to assist in removing the Eraselet® from the wrist, back over the hand for removal.
Eraselets® have elasticity so that the persons using this eraser can simply stretch the device from their wrist toward the tips of their fingers, to be gripped between their thumb and forefinger or to rest over the ball of their thumb, to make erasing marks, such as pencil and pen markings, more convenient.
Eraselets® can be used in the same manor as traditional bar or wedge erasers; erasing marks, such as pencil and pen markings, by simply holding the present invention in the hand and rubbing out such markings from a surface.
Every part of an Eraselet® may be used to erase a mark, such as a pencil mark, ink mark, the like, or indicia from a surface.
Minimal amounts of dust amass from the use of this form of eraser, making it more environmentally efficient than traditional erasers.
Furthermore, no PVC plastics are used in the production of this eraser, making it more environmentally efficient than some erasers currently in production.
Eraselets® are not consistent in design and can be made in various colors, shapes, objects, patterns, textures, and the combination thereof.
Objects may be in the form of any person, place, or thing.
Injection molds are the most common method used to manufacture silicone rubber based products. Eraselets® are formed by injecting vulcanized silicone rubber into a set mold. Once the silicone rubber has been shaped, a 4-24 hour curing process is required before an Eraselet® is ready for individual use.
These and other features, aspects, and advantages of the present invention will become better understood with regard to the following description, appended claims, and accompanying drawings where:
The preferred embodiments of the present invention will be described with reference to
An Eraselet® has an opening between all sides and is adapted to be worn on the human wrist.
Each surface extends to the center of the Eraselet® meeting the other surfaces of the Eraselet® to comprise a continuous band made of silicone rubber.
Every surface of the Eraselet® has the capability of erasing marks, such as pencil and pen markings by rubbing silicone rubber surfaces against said marks until marks disappear.
Surfaces of the Eraselet® are not constricted by shape and size; An Eraselet® can be made in the form of a continuous rectangle that forms a band, as well as a continuous circle that forms a band, as well any other various shapes that may be conceivable to form a band.
