Abstract
A system including a writing instrument including a body having a marking portion and an eraser portion, wherein the marking portion is configured to dispense a permanent ink and the eraser portion is configured to dispense a solvent which solubilizes the permanent ink.
Description
ERASABLE WRITING SYSTEM
The present invention is directed to an erasable writing system and, more particularly, to an erasable writing system having a marker with a marker portion and an eraser portion for erasing markings made by the marker portion.
BACKGROUND
Permanent markers are typically used in home, classroom or office environments for various marking purposes. Permanent markers allow a user to mark indicia on various substrates, including polymer and plastic based substrates, without the risk of the markings being smudged or accidentally erased. Permanent markers can also be used to mark on various items which cannot be written upon by other writing instruments. For example, plastic and polymer based substrates typically are not capable of being marked upon with nonpermanent inks.
Permanent markers may be advantageous in that the risk of smudging the markings is minimized once the ink has dried, thereby minimizing the risk of transference of ink to items and persons that come into contact with the markings. However, a disadvantage of permanent markers is that the markings cannot easily be erased.
Dry erase markers and the like are often used to provide an erasable marking system. Dry erase markers and the like are not permanent and their markings can easily be removed from a polymeric substrate by the application of frictional forces (i.e. by a hand or by an eraser). However, the easily erasable markings of dry erase markers can accidentally be erased and/or the markings can easily rub off on items or persons coming into contact with the markings.
Accordingly, there is a need for an erasable writing system for marking on a substrate, such as a polymer or plastic based substrate, without smudging, wherein the marking can be erased. There is also a need for a writing instrument which can write with permanent ink and which can also erase permanent ink.

DETAILED DESCRIPTION
With reference to Fig. 1, the marker or writing instrument 10 of the present invention includes a writing instrument body or marker body 12. The marker body 12 may be generally tubular or cylindrical and may have a first portion 18 and a second portion 20. The marker body 12 may include a first reservoir 14 located generally inside of the first portion 18 and a second reservoir 16 located generally inside of the second portion 20, with the first 14 and second 16 reservoirs separated by a divider 15. The marker body 12 may include a first opening 24 that is located at an end of the marker body 12 adjacent to the first portion 18 and in communication with the first reservoir 14. The marker body 12 may also include a second opening 30 that is located at the other of the marker body 12 adjacent to the second portion and in communication with the second reservoir 16.
The marker body 12 includes a first wick 22 generally closely received 15 in the first opening 24 and extending into the first reservoir 14. The first wick 22 has an exposed portion 27 extending out of the first reservoir 14, with the exposed portion 27 having a writing tip 26. The marker body 12 includes a second wick 28 generally closely received in the second opening and extending into the second reservoir 16. The second wick 28 has an 20 exposed portion 29 extending but of the second reservoir 16, with the exposed portion 29 including a tip 34. The wicks 22, 28 may be made from a wide variety of materials, such as felt. Although the marker 10 is illustrated as having a tip 26, 34 at each end, the marker 10 may have a wide variety of other configurations for the tips 26, 34 and/or wicks 22, 28, including 25 having the tips 26, 34, being oriented at various angles, being located in a side-by-side configuration, etc.
The first reservoir 14 may be filled with a permanent or indelible ink solution of any of a wide variety of colors. The permanent ink or permanent ink solution in the first reservoir 14 may be nearly any type of permanent ink 30 or ink solution, such as a traditional organic solvent based permanent ink with a wide variety of pigments, dye, colorants or the like, or an aqueous type permanent ink as described in U.S. Pat. No. 5,131,776. The permanent ink may be an alcohol based (i.e. n-propyl alcohol) or other organic solvent based permanent ink. The permanent ink may be capable of marking on porous surfaces (e.g., paper, wood and the like) and nonporous surfaces (e.g., glass, metal, plastic and other polymer b ased suraces). Ftiuthsr, the petnnazmt ink way be resistent to smearing and xe-weiting al}er application and may resist entau],sification, dissolving or removal with soap and water.
The second reservoir 16 may be filled with a solvent that can dissolve the permanent ink or ink solution in the first reservoir 14. The solvent in the second reservoir 16 may be any solvent that is capable of solubilizing or dissolving permaztmt ink or a permanent ink solution that has been applied to a surface and allowed to dzy, The solvent may be or include an ctb.yl alcohol, an n-propyl alcohol, or other organic based solvents.
For exanaple, the solvent may be a dry-erase solution typically used izt a dry-erase marker. Thus the solvent may also optionally include a colorant, dye or pigment and a binder resin such that the second portion 20 can operate as a dt'y-erase marker. In this case, when the dry-erase solution is applied to a polymeric or plastxc type surface, the solvent evaporates and the binder resin and colorant remain behind as a friable discontinuous fihn.
The permanent ink solution in the f rst reservoir 14 may be soaked through the first wick 22, or permanent ink dispensing wick 22, and wicked through the permanent ink dispensing wick 22 until the permanent ink solution reaches the writing tip 26. In this rnanner, when the writing tip 26 contacts a substrate to be written upon, ink from the frst reservoir 14 is deposited on the substrate. Sunilarly, the solvent in the second reservoir 16 soaks the second wick 28, or solvent dispensing wick 28, such that the solvent is wicked through the solvent dispensing wick 28 until it reaches the erasing tip 34. When the erasing tip 34 contacts the substrate, solvent from the second reservoir 16 is deposited onto the substrate and solubilizes (or dissolves) any ink deposited by the permanent ink dispending wick contacted by the solvent. Thus the marker 10 may be a double-ended felt-tip marker, although the na,arker 10 may include various other manners of dispensing the petmazteQO;t iutk and solvent, such as ball-point dispensers, gel-type dispensers, etc.
In. auother embodiment of the present invention, the marker 10 includes a cap 40 for coveriuag either the erasing tip 34 (as shown in Fig. 2) or, alternatively or in addition, the writing tip 26. The cap 40 prevent tbe ink and solvent from evaporatiag through the wicks 22, 28 when the marker 10 is not in use. For example, as shown in Fig. 2, the cap 40 may include a body portion shaped to form a tight interference fit or seal with the marker body 12 to seal offthe associated tip 26, 34, The cap 40 may also include am absorbent portion 42 located, for example, on an outer surface, or outer end surface, of the cap 40. The absorbent portion 42 may be made of a felt, cotton, foam, sponge-type matexxal or other absorbent type material. The absorbent portioxx 42 way be used to wipe away markings that are deposited by the writing tip 26 and erasedldissolved by the erasing tip 34. The marker 10 may include two caps 40, with each cap 401ocated on each end of the marker 10, and at least one cV 40 may include an absorbent porti on 42, although both caps 40 may include an absorbent portion 42.
As shown in Fig. 3, a user may mark various marldngs 52 on a writing svrface 50 using the wnitizg tip 26 of the marker 10. The markings 52 may then be allowed to dry. Once dry, the mazidags 52 caunot be erased by simply rubbing the markings by hand, or with soap and water or the 1ike. The pesmanent markings 52 may then be allowed to remain in place for as long as desired Once it is desired to erase the markings 52, the erasing tip 34 is applied to the markings 52 to solubilize/eraseldissolve the markxngs 52. The erasing tip 34 may be moved over the markings 52 such that the solvent contacts the deposited markings 52 and so]ubi],izes the marlouags 52, thereby allowing the marldngs 52 to be erased. A user may then take the cap 40 and apply the absoxbent poztion 42 to the wzitiua,g surface 50 to wipe away or absorb the solubilized markings.
The writing surface 50 may be made of a typical plastic material such as polypropylene, polyethylene or the like that is capable of being marked upon using permanent ink, but not with typical water based "mks. The wiiting surface 50 may have a glossy finish surface aud/ox a UV
aqueous coating andJor other coatings. Further, the writing surface 50 may have a surface rougbness su.ffi,cient to absorb or receive ink in the creases and recesses, but not exceedingly rough to make it overly difficult to remove the ink. T,zx one embodiment, the writing surface 50 has an average surface roughness of between about 9-100 microns, or between about 50-1000 microns. The writing surface 50, permanent ink and solvent should be selected such that application of the permanent ink or solvent to the writing surface 50 does not significantly alter, destroy or marr the writing surface 50. Proper selection may allow the writing surface 50 to be used many times over for marking and erasing.
The writing surface 50 may be, include, or be part of various devices or products. For example, the writing surface 50 may be formed as part of a bitrdear 60, notebook, folder, divider, portfolio, book cover ox the like for school oz business use (see Fig. 4).
Thus, for example, in school use a user may write certain notes or reminders (i.e. a reminder of a homework assignment) on the outer surface of a binder 60 which includes the writing surface 50, The writing 63 on the binder 60 is written iut permanent ink and therefore resists smudging and accidental erasuxe, even when exposed to water and most common liquids. When the user desires to remove the maxking 63 (i.a when the hoineworlt project is complete or when a new homework assignment is received) the user can remove the marldngs 63 using the erasing tip 34 and absorbent portion 42 of the cap 40.
Rather than being part of a school product, the writing surface 50 may simply be a "stand-alone" boaxd such that the writing surface 50 ca.aopezate as a bulletin board, aud, for example, be coupled to a locker, wall, refrigerator or the like, or be loosely carrier. Thus ttie writin.g surface 50 may include magnets, patches of hook-and loop fastening material (i,e, VELCIZO ), hook or other fasteners located on a rear side thereof to aid in attaching the writing surface 50 to various other components, kluther, the marker 10 (which may include the cap 40) maybe packaged together with the writing surface 50 for sale such that the uiarker 10 and writing surface 50 are marketed and sold together.
Although the invention is shown and described witb respect to certai.n embodiments, it is obvious tbat equivalents and modihcations will occur to those skilled in the arC upon reading and understanding the specification. The present invention includes all such equivalents and modifications and is limited only by the scope of the claims.
What is claimed is:
With reference to Fig. 1, the marker or writing instrument 10 of the present invention includes a writing instrument body or marker body 12. The marker body 12 may be generally tubular or cylindrical and may have a first portion 18 and a second portion 20. The marker body 12 may include a first reservoir 14 located generally inside of the first portion 18 and a second reservoir 16 located generally inside of the second portion 20, with the first 14 and second 16 reservoirs separated by a divider 15. The marker body 12 may include a first opening 24 that is located at an end of the marker body 12 adjacent to the first portion 18 and in communication with the first reservoir 14. The marker body 12 may also include a second opening 30 that is located at the other of the marker body 12 adjacent to the second portion and in communication with the second reservoir 16.
The marker body 12 includes a first wick 22 generally closely received 15 in the first opening 24 and extending into the first reservoir 14. The first wick 22 has an exposed portion 27 extending out of the first reservoir 14, with the exposed portion 27 having a writing tip 26. The marker body 12 includes a second wick 28 generally closely received in the second opening and extending into the second reservoir 16. The second wick 28 has an 20 exposed portion 29 extending but of the second reservoir 16, with the exposed portion 29 including a tip 34. The wicks 22, 28 may be made from a wide variety of materials, such as felt. Although the marker 10 is illustrated as having a tip 26, 34 at each end, the marker 10 may have a wide variety of other configurations for the tips 26, 34 and/or wicks 22, 28, including 25 having the tips 26, 34, being oriented at various angles, being located in a side-by-side configuration, etc.

The permanent ink may be capable of marking on porous surfaces (e.g., paper, wood and the like) and nonporous surfaces (e.g., glass, metal, plastic and other polymer b ased suraces). Ftiuthsr, the petnnazmt ink way be resistent to smearing and xe-weiting al}er application and may resist entau],sification, dissolving or removal with soap and water.
The second reservoir 16 may be filled with a solvent that can dissolve the permanent ink or ink solution in the first reservoir 14.
