Abstract

A marker eraser system for efficiently combining an eraser with a dry erase marker. The marker eraser system includes a body having a tubular structure and a central aperture extending through the tubular structure. The central aperture extends through an inner end to an outer end of the body. An eraser member is attached to the outer end of the eraser unit to erase a removable ink from a dry erase marker. An outer end of the central aperture frictionally receives an outer portion of a first end of a cap of the dry erase marker to allow a user to removably attach the marker eraser system to the cap of the dry erase marker.

Claims

an eraser unit comprising a body having a tubular structure and a central aperture, wherein said central aperture extends through an inner end to an outer end of said body, and wherein an outer end of said central aperture frictionally receives an outer portion of said first end of said cap;

wherein said eraser member includes an opening that corresponds to said central aperture; and

an eraser member attached to said outer end of said eraser unit.

2. The marker eraser system of claim 1, wherein said eraser member is comprised of a ring structure having an opening.

3. The marker eraser system of claim 1, wherein said outer end includes a receiver channel and wherein said eraser member is attached within said receiver channel.

4. The marker eraser system of claim 3, wherein said outer end includes a perimeter rim that surrounds said receiver channel and an inner rim that surrounds said central aperture.

5. The marker eraser system of claim 1, wherein an inner wall of said eraser unit defining said central aperture includes a plurality of ribs adjacent said outer end.

6. The marker eraser system of claim 5, wherein said plurality of ribs are substantially parallel to one another.

7. The marker eraser system of claim 5, wherein said plurality of ribs frictionally and catchably engage a plurality of raised members, wherein said plurality of raised members extend outwardly from said cap adjacent said first end.

8. The marker eraser system of claim 7, wherein said plurality of raised members are comprised of a cincture structure.

9. The marker eraser system of claim 1, wherein an inner wall of said eraser unit defining said central aperture includes an engaging portion that extends inwardly and includes a plurality of ribs, wherein a rib portion of said plurality of ribs is adjacent said outer end.

10. The marker eraser system of claim 9, wherein said central aperture is comprised of a consistent diameter and wherein said engaging portion extends inwardly with respect to said central aperture.

11. The marker eraser system of claim 1, wherein an outer portion of said body is comprised of a tapering structure.

12. A marker eraser system, comprising:

a writing instrument including a cap, a writing end and a receiver end;

wherein said cap includes a first end and a second end, wherein said first end is removably connectable to said writing end to selectively cover a writing tip and wherein said second end is removably connectable to said receiver end;

an eraser unit comprising a body having a tubular structure and a central aperture, wherein said central aperture extends through an inner end to an outer end of said body, and wherein an inner end of said central aperture frictionally receives an outer portion of said first end of said cap;

wherein said central aperture is comprised of a consistent diameter and wherein an engaging portion of said outer end extends inwardly with respect to said central aperture; and

an eraser member attached to said outer end of said eraser unit, wherein said eraser member is comprised of a ring structure having an opening that corresponds to said central aperture, wherein said opening is similar in shape and size to said central aperture;

wherein said outer end includes a receiver channel and wherein said eraser member is attached within said receiver channel.

13. The marker eraser system of claim 12, wherein said outer end includes a perimeter rim that surrounds said receiver channel and an inner rim that surrounds said central aperture.

14. The marker eraser system of claim 12, wherein an inner wall of said eraser unit defining said central aperture includes a plurality of ribs adjacent said outer end.

15. The marker eraser system of claim 14, wherein said plurality of ribs are substantially parallel to one another.

16. The marker eraser system of claim 14, wherein said plurality of ribs frictionally and catchably engage a plurality of raised members, wherein said plurality of raised members extend outwardly from said cap adjacent said first end.

17. The marker eraser system of claim 16, wherein said plurality of raised members are comprised of a cincture structure.

18. The marker eraser system of claim 12, wherein an inner wall of said eraser unit defining said central aperture includes an engaging portion that extends inwardly and includes a plurality of ribs, wherein a rib portion of said plurality of ribs is adjacent said outer end.

19. An eraser system for a dry erase marker, comprising:

an eraser unit comprising a body having a tubular structure and a central aperture, wherein said central aperture extends through an inner end to an outer end of said body, and wherein an inner end of said central aperture frictionally receives an outer portion of a first end of a cap;

wherein said central aperture is comprised of a consistent diameter and wherein an engaging portion extends inwardly with respect to said central aperture; and

an eraser member attached to said outer end of said eraser unit, wherein said eraser member is comprised of a ring structure having an opening that corresponds to said central aperture, wherein said opening is similar in shape and size to said central aperture;

wherein said outer end includes a receiver channel and wherein said eraser member is attached within said receiver channel;

wherein said outer end includes a perimeter rim that surrounds said receiver channel and an inner rim that surrounds said central aperture;

wherein an inner wall of said eraser unit defining said central aperture includes a plurality of ribs adjacent said outer end, wherein said plurality of ribs form an engaging portion that extends inwardly with respect to said central aperture;

wherein said plurality of ribs frictionally and catchably engage a plurality of raised members, wherein said plurality of raised members extend outwardly from said cap adjacent said first end;

wherein said plurality of raised members are comprised of a cincture structure;

wherein said plurality of ribs are substantially parallel to one another.

20. A marker eraser system, comprising:

a writing instrument including a cap, a writing end and a receiver end;

wherein said cap includes a first end and a second end, wherein said first end is removably connectable to said writing end to selectively cover a writing tip and wherein said second end is removably connectable to said receiver end;
