- 1. Field of the Invention
- The present invention relates generally to dry marker erasers. Specifically, the invention relates to a dry marker eraser having a reusable body and a disposable cleaning sheet removably attached to the body, and to a dispenser for the disposable cleaning sheets.
- 2. Description of the Related Art
- Dry marker erasers have been used for many years to remove multiple color markings from white boards. Conventional handheld felt dry marker erasers are very similar in size to the standard chalkboard type erasers. Such erasers are often supplied for use in cleaning markings off of the whiteboard in order to prepare the whiteboard for another set of markings.
- A problem with conventional dry marker erasers is that after several uses, the user often finds the eraser consumed or saturated with the residue from erased dry markings, such that the eraser is ineffective to remove any more markings. Unlike chalkboard dust, the user cannot simply pat off enough the residue to make the eraser effective again.
- As a result of this problem, the user must periodically seek out a new eraser, usually in the midst of a presentation. The search for a new eraser tends to disrupt the presentation of the user, as well as limiting the time the user has to make his/her presentation. The following references provide examples of the conventional dry marker type erasers.

For example, the attachment means may be a surface coating of a releasable adhesive, or ahook fabric fastener 32 of the type used in hook and loop fastening material. When the attachment means is an adhesive, the adhesive maintains thebottom surface 30 in a tacky state sufficient for adherence of acleaning sheet 34 to thebottom surface 30. When the attachment means is ahook fabric fastener 32, the properties of the fabric from which thecleaning sheet 34 is made permit releasable attachment of thecleaning sheet 34 to thebottom surface 30 without the necessity of adhering a separate sheet of loop fastening material to thecleaning sheet 34. - Each one of the
cleaning sheets 34 has a rectangular form corresponding to or congruent to thebottom surface 30 of theeraser body 22. Referring to asingle sheet 34, the descriptions and properties apply to all of thecleaning sheets 34. Thecleaning sheet 34 has athickness 36, and top and bottom surfaces 38. Thecleaning sheet 34 is formed of woven or non-woven fibrous fabric material. The fibrous material, when formed into thecleaning sheet 34, is a pile type fabric having a plurality of looping eyelets (not shown) along the top and bottom surfaces 38. The looping eyelets of thecleaning sheet 34 mate with thehook fabric fastener 32 in order to attach thecleaning sheet 34 to thebottom surface 30 of theeraser body 22. - When the attachment means is an adhesive coating, the looping eyelets are adhesively attached to the adhesive coating on the
bottom surface 30 of theeraser body 22. When the attachment means is thehook fabric fastener 32, the looping eyelets are attached to thehook fastener 32 as in conventional hook and loop fasteners. In either scenario, thetop surface 38 thecleaning sheet 34 is securely adhered to thebottom surface 30 of theeraser body 22. - The looping eyelets also provide the
bottom surface 38 of thecleaning sheet 34 with the cleaning ability for cleaning whiteboard. Referring to FIG. 4, the eyelets allow thecleaning sheet 34 to completely removemarkings 48 fromwhiteboard 40. The eyelets of thecleaning sheet 34 nonabrasively scour thewhiteboard 40 surface, thereby removing themarkings 48 and collecting the removed markings as marker dust within thethickness 36 of cleaningsheet 34. After using thecleaning sheet 34 several times, thecleaning sheet 34 becomes saturated with, or consumed by, the marker dust and is thusly rendered unusable. Once thecleaning sheet 34 is saturated or consumed, it is discarded and replaced by anew cleaning sheet 34. - According to the present invention, a storage/
dispenser box 12 having a closed bottom (not shown), an open top 14, twoclosed side walls 16, and forward andrear walls 18 is provided. The twoclosed side walls 16 and the forward andrear walls 18 arise from the closed bottom and define a rectangular form. The plurality of cleaningsheets 34 and thesupport member 22 are dimensioned and configured to fit within the rectangular form defined by the storage/dispenser box 12. The rectangular form defined by the storage/dispenser box 12 is sized and configured to hold thecleaning sheets 34 and theeraser body 22 in a vertical stack, such that the interior perimeter of thebox 12 circumscribes the exterior perimeter of thecleaning sheets 34 and theeraser body 22. Thereby, thedispenser box 12 may be used to package both thedry marker eraser 10 and thecleaning sheets 34. - The
dispenser box 12 provides additional utility. In particular, the forward andrearward walls 18, include a centrally disposed substantiallyU-shaped cutout 20. TheU-shaped cutout 20 provides access to theeraser body 22 as it rests atop the vertical stack of cleaningsheets 34. Theeraser body 22 is readily grasped from the top of the stack, theU-shaped cutouts 20 allowing theuser 44 to grasp theeraser body 22 by its side surfaces 26 even though the top of the stack of cleaningsheets 34 is lowered as more cleaning sheets are used and disposed of. Thedispenser box 12 serves to properly align thecleaning sheet 34 with thebottom surface 30 of theeraser body 22 so that theuser 44 does not have to struggle with installation of thecleaning sheet 34 on theeraser body 22. - Another convenience provided by the
box 12, is that the storage/dispenser box 12 is dimensioned to be disposed on aledge 42 of thewhiteboard 40, as shown in FIG. 4. This convenience allows thereplacement cleaning sheets 34 to be readily accessible as theuser 44 works on thewhiteboard 40. If thecleaning sheets 34 were stored in a supply cabinet, each time acleaning sheet 34 is consumed and discarded auser 44 would have to leave the vicinity of thewhiteboard 40 go to the supply cabinet and retrieve anew cleaning sheet 34. The ability to reside on theledge 42 of thewhiteboard 40 clearly makes thedry marker eraser 10 of the present invention user-friendly. - In use, the
dispenser box 12 is placed on theledge 42 ofwhiteboard 40. Auser 44 makesmarkings 48 on thewhiteboard 40 with dry erase markers (not shown). When an error occurs, or whennew markings 48 are to be added to thewhiteboard 40, theuser 44 grasps theeraser body 22 via theU-shaped cutouts 20 from thebox 12. Due to the attachment means on thebottom surface 30 of theeraser body 22, acleaning sheet 34 is securely attached thereto. The user whisks theeraser body 22 across thewhiteboard 40 so that thecleaning sheet 34 rubs over themarkings 48, and removes them, the marker dust being collected within thethickness 36 of cleaningsheet 34. - Upon cleaning
sheet 34 becoming saturated or consumed with the marker dust, the effective cleaning ability is diminished. Promptly, theuser 44 will grasp a corner or end of thecleaning sheet 34 and peel, or otherwise, remove thecleaning sheet 34 from theattachment unit 32. Once removed, thecleaning sheet 34 is preferably discarded in a conveniently located refusereceptacle 46. Theuser 44 then places theeraser body 22,bottom surface 30 down, on the remaining stack of cleaningsheets 34 in thebox 12. The attachment means immediately attaches thesurface 38 of thetopmost cleaning sheet 34, thereby making the eraser ready for immediate usage. - It is to be understood that the present invention is not limited to the embodiments described above, but encompasses any and all embodiments within the scope of the following claims.
