## Background
BACKGROUND OF THE INVENTION
The present invention generally relates to a marking device, a method of using the same and an accessory kit for a marking device. More specifically, the present invention relates to a marking device, a method of using the same and an accessory kit for a marking device that provide a sheath that fits over a marking device, such as, for example, a pen, and further relates to an end cap that fits on the end of the marking device. Further, the present invention relates to a marking device, a method of using the same and an accessory kit for a marking device that contains an antimicrobial substance on the sheath for sterilizing the sheath.
It is, of course, generally known to provide a marking device, such as, for example, a pen, a pencil or other like marking device. Further, it is known to design marking devices so that the devices are comfortable to hold. Of course, many writing instruments are difficult and/or uncomfortable to hold and, during use of the same, users often experience the development of calluses or like friction points on the hands or fingers of the users, particularly those fingers which grip the writing instrument. Further, often handicaps or other difficulties arise with certain individuals making it difficult or uncomfortable to hold or grip a writing instrument.
It is also generally known to provide a marking device in, for example, a public area, such as a school, an office, a hospital, a retail store or the like, that may be chained or otherwise connected to a permanent structure such as, for example, a desk or a wall. Many such marking devices are configured to have the chain or connecting device integrally formed and extending from the marking device through an end of the marking device. To remove the marking device from the chain, a link may be removed from the chain thereby separating the marking device and a certain length of chain from the remainder of the chain that is attached to the permanent structure. This may make it difficult to replace the marking device to the connecting device when the marking device no longer functions or otherwise is depleted of writing material such as, for example, ink.
Moreover, marking devices used in, for example, the aforementioned public areas are susceptible to contact with bacteria, viruses and/or other microbes on the surface of the marking device. Subsequent contact with the marking device by other individuals in a public area may increase the likelihood of exposure to the bacteria, viruses and/or the microbes thereby likely causing illness or disease to spread.

The sheath 10 may fit snugly on a barrel of a marking device, such as, for example, a pen, a pencil or other like marking device, that may be apparent to those skilled in the art. Further, the sheath 10 may be removable from the marking device for replacement purposes or for depositing more of the antimicrobial agent to the sheath 10.
FIG. 2 generally illustrates a marking device 50 having a barrel 52. The barrel 52 may have a first end 54 and a second end 56. The marking device 50 may be any device capable of producing a mark with a tip 58, such as a pen, a pencil or any other like marking device. The cross-sectional shape of the barrel 52 may be circular as shown in FIG. 2. However, the barrel 52 may have any other cross-sectional shape that may be apparent to those skilled in the art. For example, the cross-sectional shape of the barrel 52 may be square, triangular-shaped, multi-sided or any other shape that may be apparent to those skilled in the art. Further, the sheath 10, as shown in FIG. 1, may be designed to conform to any shape of the barrel 52.
Still referring to FIG. 2, the barrel 52 may have a sheath 60 secured thereon. The sheath 60 may have a split section 62 and further may have bands 64 that may be utilized to fasten over the sheath 60 to fix the sheath 60 to the barrel 52. The bands 64 may have screws 66 or other like fastening means that may be attached to the band 60 and utilized to tighten or clamp the bands 64 over the sheath 60. The bands 64 may have apertures for the screws 66 to fit therethrough. For example, as shown in FIG. 2, the bands 64 may have ends that overlap thereby allowing the apertures contained within the bands 64 to overlap as well. The screws 66 may fit through the apertures. Tightening of the screws 66 may tighten the sheath 60 to the barrel 52. Any number of bands may be utilized to fix or clamp the sheath 60 onto the barrel 52. Further, any connecting means may be utilized to tighten the bands 64 to the sheath 60 as may be apparent to those skilled in the art.
The sheath 60 may be a rectangular piece of material when laid on a flat surface but may wrap around the barrel 52 of the marking device 50 to be fixed in place by the bands 64. When placed around the barrel 52, the sheath 60 may partially cover the barrel 52. Moreover, when placed around the barrel 52, the sheath 60 may form the split 62 between two ends of the sheath 60. Alternatively, the two ends of the sheath 60 may overlap (not shown).
A tool 68 may be utilized to fasten the screws 66 onto the bands 64 thereby fixing or clamping the sheath 60 to the barrel 52. The tool 68 may be specially designed to aid in attaching the sheath 60 to the barrel 52 or may be any other tool that may aid in this process.
Further, the sheath 60 may contain the antimicrobial agent thereon to kill bacteria, viruses, fungi or any other like microbial substances or disease-causing substances as described in U.S. Pat. No. 6,019,533, the disclosure of which is incorporated by reference herein in its entirety.
Fixed on the second end 56 of the barrel 52 may be an end cap 70 having a connecting lead 72 extending therefrom. The end cap 70 may fit over the second end 56 of the barrel 52. The end cap 70 may have an opening 73 that is slightly larger than the width of the barrel 52. The end cap 70, therefore, may fit snugly over the second end 56 of the barrel 52 thereby fixing the end cap 70 to the marking device 50. Additionally, the end cap 70 may be constructed of a rubberized material having a degree of pliability that may allow the end cap 70 to fit over other shaped barrels. For example, the end cap 70 may have a generally circular-shaped opening 73. However, the end cap 70 may be pliable and may fit over the end of a triangular-shaped barrel or other shape barrel that may be apparent to those skilled in the art.
Alternatively, the end cap 70 may have screw threads therein. The screw threads may engage with screw threads that may be contained on the second end 56 of the barrel 52 thereby causing the end cap to become fixed to the second end 56 of the barrel 52. However, any other attaching means may be utilized to attach the end cap 70 to the marking device 50, and the present invention should not be construed as limited in any way as herein described. Any attaching means may be utilized to connect the end cap 70 to the marking device 50 that may be apparent to those skilled in the art.
The connecting lead 72 may extend from the end cap 70 and may be integrally formed with the end cap 70.
